Granulomatous lobular mastitis is a rare chronic inflammatory disease that has clinical and radiologic findings similar to those of breast cancer. We performed a retrospective analysis of clinical, imaging, and treatment findings in 54 women diagnosed with granulomatous lobular mastitis between January 2000 and April 2008. The imaging findings of granulomatous lobular mastitis overlap with those of malignancy. The most common presentation is a focal asymmetric density on mammography and an irregular hypoechoic mass with tubular extensions on ultrasound. Core biopsy is typically diagnostic. Once the diagnosis is established by tissue sampling, corticosteroids are the first line of treatment.

Interstitial granulomatous dermatitis with arthritis is an uncommon systemic disorder involving the cutaneous and musculoskeletal systems. The eruption may mimic other dermatoses including granuloma annulare, erythema chronicum migrans, and the inflammatory stage of morphea. Key histopathologic characteristics, along with clinical correlation, allow accurate diagnosis. We describe the clinical, serologic, and histologic features in three patients with interstitial granulomatous dermatitis with arthritis. Skin biopsy specimens were examined and correlated with the clinical and laboratory findings. Erythematous, annular, indurated plaques on the extremities were present in two women. An erythematous, papular eruption on the head and neck was present in a third patient. All patients had myalgia and migratory polyarthralgias of the extremities along with various serologic abnormalities. Histologic examination revealed a dense lymphohistiocytic interstitial infiltrate involving primarily the reticular dermis. Foci of necrobiotic collagen were present. Vasculitis was absent. Interstitial granulomatous dermatitis with arthritis is unique multisystem disease with variable cutaneous expression. Abnormal serologic findings indicate a possible connection to collagen vascular disease.

Objective To study idiopathic granulomatous mastitis with respect to its various clinical features, etiologic factors, treatment modalities and complications. Material and methods Retrospective study of all patients who were diagnosed with idiopathic granulomatous mastitis from 1st January 2006 to 31st December 2014 at Kasturba Hospital, Manipal, India (a tertiary care referral centre). The research was performed according to the World Medical Association Declaration of Helsinki. Informed consent was taken from the patient before invasive procedures including surgery. Data was analysed using the Statistical Package for Social Sciences version 16.0 wherever appropriate. Results 73 patients diagnosed with idiopathic granulomatous mastitis during the time period were included. One patient was a male (1.37%), rest were all females (98.63%). The mean age of presentation was 32.67 years (range 23 to 66 years). 70 patients (95.89%) were parous females. Average duration since last childbirth was 4.6 years (range: 3 months to 33 years). 8 patients (10.95%) were lactating. History of oral contraceptive pill use was present in 40 patients (54.79%). The right breast was affected in 44 patients (60.27%), and the left breast in 29 patients (39.73%). None of the patients had bilateral disease. The most common symptom was a painless lump (61.64%). Rest of the patients (38.36%) presented with features of a breast abscess. 19 out of 39 FNACs done (48.72%) were positive for granulomatous mastitis. 59 were primarily managed surgically (lumpectomy/wide excision-33, incision & drainage-26). One patient was treated primarily with prednisolone. 13 patients did not receive specific treatment, and were only kept on regular follow-up. Patients managed with lumpectomy/wide excision had the least rate of complications & recurrence (18.18%). Conclusion Patients with idiopathic granulomatous mastitis can present with a wide variety of symptoms which mimic other more common conditions. Surgical

Idiopathic granulomatous mastitis is a chronic inflammatory disease of the breast, which is often difficult to differentiate both clinically and radiologically from infectious aetiologies such as tuberculosis, fungal infections, and also from malignancy, thus posing a diagnostic dilemma. We present a pictorial review of the commonly encountered imaging findings in idiopathic granulomatous mastitis on mammography and ultrasound. Mammographic and ultrasound findings of histopathologically proven cases of granulomatous mastitis are discussed. Idiopathic granulomatous mastitis has varied and non-specific appearances on ultrasound and mammography. Histopathology is essential to establish diagnosis. • Idiopathic granulomatous mastitis often poses a diagnostic dilemma for the radiologist by mimicking malignancy. • It has varied and non-specific appearances on mammography and ultrasound. • Histopathology is mandatory to establish the diagnosis and decide management.

Granulomatous responses in larval taeniid infections.

PubMed

Díaz, Á; Sagasti, C; Casaravilla, C

2018-05-01

Granulomas are responses to persistent nonliving bodies or pathogens, centrally featuring specialized macrophage forms called epithelioid and multinucleated giant cells. The larval stages of the cestode parasites of the Taeniidae family (Taenia, Echinococcus) develop for years in fixed tissue sites in mammals. In consequence, they are targets of granulomatous responses. The information on tissue responses to larval taeniids is fragmented among host and parasite species and scattered over many decades. We attempt to draw an integrated picture of these responses in solid tissues. The intensity of inflammation around live parasites spans a spectrum from minimal to high, parasite vitality correlating with low inflammation. The low end of the inflammatory spectrum features collagen capsules proximal to the parasites and moderate distal infiltration. The middle of the spectrum is dominated by classical granulomatous responses, whereas the high end features massive eosinophil invasions. Across the range of parasite species, much observational evidence suggests that eosinophils are highly effective at killing larval taeniids in solid tissues, before and during chronic granulomatous responses. The evidence available also suggests that these parasites are adapted to inhibit host granulomatous responses, in part through the exacerbation of host regulatory mechanisms including regulatory T cells and TGF-β. © 2018 John Wiley & Sons Ltd.

We report a case of a rare inflammatory disease, granulomatous lobular mastitis. Two weeks prior to admission the patient, a 43 year-old woman, (gravida 1, para 1) had noticed a left breast mass associated with tenderness. Palpation, gross inspection, and clinical examination, as well as the rapid growth of the mass lesion led us to believe that it was highly suspicious of malignant neoplasm. Mammography, ultrasonography, and computed tomography did not differentiate it from a malignant neoplasm. Aspiration cytology revealed an inflammatory lesion with a few clusters of epithelial cells it was diagnosed as borderline malignancy(class III) by a prudent pathologist, and thus mastectomy was performed. However, the final histologi-cal diagnosis was granulomatous lobular mastitis with no evidence of malignancy. As the clinical manifestations of granulomatous mastitis are similar to those of mammary carcinoma and, as it is an inflammatory lesion of uncertain etiology and pathogenesis, it has often been mistaken clinically for carcinoma and treated as such. Our review of the literature indicated that granulomatous mastitis most often occurs in young patients with a history of childbirth or oral contraceptive usage. Recurrence was documented in 38% of patients, and, accordingly long-term follow-up by aspiration cytology, complete resection, and adequate drug treatment with corticosteroids are recommended.

Objectives: Idiopathic granulomatous mastitis (IGM) is a rare benign disorder of the breast whose aetiology is controversial, and is often misdiagnosed clinically and radiologically as mammary malignancy; as a result, it may be incorrectly treated. Although no standard treatment is available for this chronic disease, surgery with or without corticosteroids has been tried with controversial results. This study discusses the clinical presentation, diagnosis, management, recurrence, and follow-up data of IGM with a review of relevant literature. Methods: From 2009–2012, the Breast Unit at Sultan Qaboos University Hospital, Oman, conducted a clinical study on 20 patients with breast lumps. Their clinical and radiological examinations were indeterminate, and a diagnosis of granulomatous mastitis was established only by histopathology. Results: The majority of the patients were cases of unknown aetiology, who presented with a unilateral breast mass. A few patients had a mass with an abscess, along with axillary lymphadenopathy. A total of 4 patients were suspected of malignancy using radiology. In all patients, sterilised pus was sent for culture and sensitivity. Microscopy showed the characteristic pattern of granulomatous inflammation. All patients were treated with antibiotics for 6 weeks, and the mean follow-up period was 15 months (11–33 months). All patients had complete remission with no further recurrence. Conclusion: This single largest study of cases of IGM in Oman highlights the pitfalls in diagnosing this non-neoplastic disease of unknown aetiology and uncertain pathogenesis. It emphasises IGM’s excellent response to antibiotics, which is crucial, as IGM is a disease which is notoriously difficult and controversial to treat. PMID:23862029

To describe the clinical and paraclinical characteristics of idiopathic granulomatous mastitis, the management of our patients, and review the literature on this topic. Patients referred to our clinic with a presumptive diagnosis of infectious mastitis were only included in the study if they had histopathologic confirmation of granulomatous mastitis. A systemic or infectious etiology was excluded by the testing of tissues and fluids by staining, culture, and polymerase chain reaction methods. Those patients with no reported etiology were categorized as idiopathic granulomatous mastitis and treated with antiinflammatory drugs. All were monitored for signs of recurrence. All 22 patients with a final diagnosis of idiopathic granulomatous mastitis were women with a mean age (± standard deviation) of 32.8 ± 6.2 years. Initial treatment with a prednisone regimen was given in 15 (68.2%) patients, prednisone plus methotrexate (MTX) in six (27.3%), and MTX alone in one (4.5%). Among the total of 22 patients with idiopathic granulomatous mastitis, 12 (54.5%) received MTX either as an initial treatment or as an alternative regimen. Of the 22 patients, three (13.6%) had disease recurrence and four (18.2%) experienced adverse drug reactions. Sixteen (72.7%) patients discontinued the initial treatment regimen with acceptable control of disease activity and without recurrence or adverse drug reactions during the follow-up period. Idiopathic granulomatous mastitis is a distinct benign breast condition of unknown etiology but several triggers are suspected, including inflammatory, infectious, and hormonal factors. Corticosteroids and MTX, with or without surgery, are the treatment of choice in these patients.

Idiopathic granulomatous mastitis, also known as idiopathic granulomatous lobular mastitis, is a benign breast lesion that represents both a diagnostic and therapeutic dilemma. We report two cases of granulomatous mastitis recently evaluated and managed at our institution. To better understand this rare disease, we analyzed treatment outcomes in reported cases of granulomatous mastitis. One hundred sixteen cases were subsequently analyzed. Primary management strategies included observation (n = 9), steroids (n = 29), partial mastectomy (n = 75), and mastectomy (n = 3). Success rates with each treatment were observation, 56 per cent; steroids, 42 per cent; partial mastectomy, 79 per cent; and mastectomy, 100 per cent. Based on this analysis, we propose a clinically useful algorithm for both workup and management of these challenging cases.

Palisaded neutrophilic and granulomatous dermatitis and interstitial granulomatous dermatitis are uncommon granulomatous dermatoses that often arise in association with rheumatoid arthritis. These 2 entities have overlapping features and may exist on a spectrum. We report an intriguing case of a 53-year-old man with advanced rheumatoid arthritis who presented with a large indurated painful truncal plaque with a palpable cord in addition to a papulonodular eruption on his dorsal hands. Furthermore, our patient had a recurrence in a near-identical mirror-image pattern on the contralateral trunk. The constellation of clinical and histopathological findings in our patient further suggests that palisaded neutrophilic and granulomatous dermatitis and interstitial granulomatous dermatitis exist as overlapping disease entities on a continuum. In addition, we propose that recurrence of skin findings may be indicative of the severity of the underlying systemic disease process.

Granulomatous infections are commonly associated with mycobacteria, brucellosis, actinomycosis, nocardiosis, spirochetes, and fungi. Rarely, granuloma formation is a host response to other bacterial infection. Osteomyelitis and osteitis that reactivate many years after the primary episode is a known phenomenon. A reactivation that presents as a granulomatous disease is rare. We present a case of reactivated osteitis due to Moraxella osloensis with consecutive granuloma formation.

To review clinical presentation, revisit patient demographics and imaging findings in granulomatous mastitis and determine the optimal biopsy method for diagnosis. A retrospective study was performed to review the clinical presentation, imaging findings and biopsy methods in patients with granulomatous mastitis. Twenty-seven patients with pathology-proven granulomatous mastitis were included. The average age at presentation was 38.0 years (range, 21-73 years). Seven patients were between 48 and 73 years old. Twenty-four patients presented with symptoms and three patients were asymptomatic. Nineteen patients were imaged with mammography demonstrating mammographically occult lesions as the predominant finding. Twenty-six patients were imaged with ultrasound and the most common finding was a mass lesion. Pathological diagnosis was made by image-guided biopsy in 44 % of patients. The imaging features of granulomatous mastitis on mammography are infrequently described. Our study demonstrates that granulomatous mastitis can occur in postmenopausal or asymptomatic patients, although previously reported exclusively in young women with palpable findings. Presentation on mammography as calcifications requiring mammographically guided vacuum-assisted biopsy has not been previously described. The diagnosis of granulomatous mastitis can easily be made by image-guided biopsy and surgical excision should be reserved for definitive treatment. • Characterizes radiographic appearance of granulomatous mastitis in postmenopausal or asymptomatic patients. • Granulomatous mastitis can present exclusively as calcifications on mammography. • The diagnosis of granulomatous mastitis is made by image-guided biopsy techniques.

Chronic granulomatous disease is a rare inherited disorder of the innate immune system. In patients with a clinical history of recurrent or persistent infections, especially infections caused by uncommon species, chronic granulomatous disease should be considered. We report the case of a 5-year-old boy with a presumptive diagnosis of Crohn's disease with extraintestinal manifestations. Chronic granulomatous disease was suspected in this case after Serratia marcescens was isolated from a skin ulcer culture. Granulomas were confirmed on histology and chronic granulomatous disease was diagnosed. This case emphasizes the importance of high clinical suspicion of an alternative diagnosis of immune deficiency in patients with presumed inflammatory bowel disease and opportunistic infections, especially when disease occurs in early life.

Aims Coexistence of lung cancer and granulomatous inflammation in the same patient confuses clinicians. We aimed to document the prevalence, clinicopathological features, treatment outcomes and prognosis in patients with coexisting granulomatous inflammation undergoing curative lung resection for lung cancer, in a tuberculosis (TB)-endemic country. Methods An observational cohort study of patients with lung cancer undergoing curative resection between 2012 and 2015 in a tertiary centre in Singapore. Results One hundred and twenty-seven patients underwent lung resection for cancer, out of which 19 (14.9%) had coexistent granulomatous inflammation in the resected specimen. Median age was 68 years and 58.2% were males. Overall median (range) survival was 451 (22–2452) days. Eighteen (14%) patients died at median duration of 271 days after surgery. The postsurgery median survival for those alive was 494 (29–2452) days in the whole group. Subgroup analysis did not reveal any differences in age, gender, location of cancer, radiological features, type of cancer, chemotherapy, history of TB or survival in patients with or without coexistent granulomatous inflammation. Conclusions Incidental detection of granulomatous inflammation in patients undergoing lung resection for cancer, even in a TB-endemic country, may not require any intervention. Such findings may be due to either mycobacterial infection in the past or ‘sarcoid reaction’ to cancer. Although all patients should have their resected specimen sent for acid-fast bacilli culture and followed up until the culture results are reported, the initiation of the management of such patients as per existing lung cancer management guidelines does not affect their outcome adversely.

Two cases of a lobular, necrotizing granulomatous process causing a unilateral painful breast mass mimicking carcinoma are presented for comparison. While the morphologic appearance in each case was that of lobular granulomatous mastitis, the etiologic agent in one case appeared to be Histoplasma capsulatum, based on Grocott methenamine silver staining, and represents the second reported case of histoplasmosis involving only breast parenchyma. Awareness of the rare entity, granulomatous mastitis, is important for the pathologist because the definitive diagnosis is made microscopically. Thorough evaluation of the breast tissue is essential for its management and should eventually contribute to the clarification of its etiology.

Sporotrichosis is a subcutaneous mycosis caused by Sporothrix complex, endemic in Abancay, Peru. Is acquired by traumatic inoculation with plant material. Common clinical presentations are lymphatic cutaneous and fixed cutaneous disease. We report 2 cases of fixed cutaneous sporotrichosis with granulomatous appearance. The first case was a patient of 65 years old with no risk factors and the second case was a 67 year old diabetic patient. Subjects underwent mycological culture with Sabouraud agar, with isolation of Sporothrix schenckii and clinical dignosis of fixed cutaneous sporotrichosis with granulomatous appearance. One patient received oral treatment with saturated solution of potassium iodide (SSKI) with a initial dose of 3 drops tid up to a maximum dose of 40 drops tid. Mycological and clinical cure was achieved after 2 months of treatment. We should consider the unusual clinical presentations of fixed cutaneous sporotrichosis with granulomatous appearance that present morphological and clinical features in diabetic and nondiabetic patients older than 60 years from endemic areas and communicate adequate response to treatment with SSKI in one case.

We report a case of idiopathic granulomatous mastitis in a 35-year-old Japanese woman, who came to our hospital complaining of a tender mass in her right breast. Because the results of initial aspiration cytology were considered highly suspicious for carcinoma, modified radical mastectomy was performed. However, the final histological diagnosis was granulomatous lobular mastitis with no evidence of malignancy. Idiopathic granulomatous mastitis is a rare inflammatory breast disease of unknown etiology. Since the clinical manifestations are similar to those of mammary carcinoma, this condition has been misdiagnosed as carcinoma and treated as such. A review of the literature revealed that idiopathic granulomatous mastitis has tended to occur in young patients with a history of childbirth or oral contraceptive usage. Clinical or imaging diagnosis has often been difficult. Complete resection or corticosteroid therapy can be recommended as the optimal treatment. Since 38% of patients experience recurrence, long-term follow-up is indicated.

Granulomatous lobular mastitis (GLM) is a rare disorder that can clinically mimic breast carcinoma. The recommendation for diagnosis and treatment of GLM has not yet been established. To assess a series of GLM patients, including their clinical presentation, diagnosis, treatment and outcome. We retrospectively analyzed the clinical data and treatment of 17 female patients with biopsy-proven GLM. Breast tissue was obtained by a core needle biopsy (15 patients) or open biopsy (2 patients). Images were reviewed by an experienced radiologist. The mean age of the patients at diagnosis was 44.6 ± 12.6 years. Five patients (29%) presented with bilateral disease, and seven (41%) presented with a mass, suggesting the initial diagnosis of breast carcinoma. Treatment comprised observation alone (23%), antibiotics (58.8%) and/or corticosteroids (with or without methotrexate) (35%). At the end of the study 70.6% of the patients demonstrated complete remission. None of the patients developed any systemic (granulomatous) disease or breast carcinoma during the follow-up period (4.7 ± 3.8 years). Core needle biopsy is mandatory for the diagnosis of GLM and the exclusion of breast carcinoma. The recommended treatment modalities are observation alone or corticosteroids; surgery should be avoided. GLM is a benign disease with a high rate of resolution and complete remission.

We searched retrospectively addresses, phone numbers and clinical files of 93 patients whom diagnosed granulomatous mastitis between a decade of January 2001 - December 2010. We noted demographic specialties, ages, gender, medical family history, main complaints, physical findings, radiological and laboratory findings, medical treatments, postoperative complications and surgical procedures if they were operated; morbidity, recurrence and success ratios, complications after treatment for patients discussed above. In this study we evaluated 93 patients, 91 females and 2 males, with granulomatous mastitis retrospectively who applied to General Surgery Department of Atatürk University Medical Faculty between January 2001 and December 2010. Mean age was 34.4 years. The diagnosis was confirmed by histopathologic examination of the lesions. Seventy three patients had idiopathic granulomatous lobular mastitis and 20 patients had specific granulomatous mastitis IGM (18 tuberculosis mastitis, 1 alveolar echinococcosis and 1 silk reaction). All the patients had surgical debridement or antibiotic, and anti-inflammatory treatment with results bad clinical response before applied our clinic. Empiric antibiotic therapy and drainage of the breast lesions are not enough for complete remission of idiopathic granulomatous mastitis. The lesion must be excised completely. In selected patients, corticosteroid therapy can be useful. In the patients with tuberculous mastitis, abscess drainage and antituberculous therapy can be useful, but wide excision must be chosen for the patients with recurrent disease.

Idiopathic granulomatous mastitis (IGM) is a benign, aseptic inflammatory disease of unknown origin, which must be distinguished from tumoral and infectious processes that affect the breast, including tuberculosis. IGM is a rare cause of erythema nodosum, but it is useful for dermatologists to be aware of this association. A 32-year-old nulliparous woman presented with erythema nodosum, arthralgia and fever. On examination, she had a firm and painful mass of 5cm in the right breast with retraction and axillary adenopathy. The breast lump developed gradually over the preceding 4 months. Although two biopsies showed no evidence of atypical cells, inflammatory areas and a granulomatous process were seen. Culture of breast tissue for mycobacteria was negative. A diagnostic of idiopathic granulomatous mastitis was made. Systemic corticosteroids led to a reduction in size of the mass, but relapse occurred in the contralateral breast on dose-reduction of the corticosteroids. IGM is a rare disease of unknown aetiology. Diagnosis is based on characteristic histological features and exclusion of other granulomatous diseases. Extra-mammary signs are rare and include erythema nodosum, arthralgia and episcleritis. Management is poorly codified. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

Pulmonary granulomatous reaction: talc pneumoconiosis or chronic sarcoidosis?

PubMed Central

Tukiainen, P; Nickels, J; Taskinen, E; Nyberg, M

1984-01-01

A chronic pulmonary granulomatous reaction was associated with an almost identical clinical picture in two patients exposed to talc. In both patients lung biopsy showed the deposition of talc particles and a heavy granulomatous reaction. At the time of diagnosis the Kveim test result was negative in both patients, urinary calcium excretion was normal, and there were no extrapulmonary manifestations and no response to steroid treatment. These findings point against sarcoidosis. The serum angiotensin-converting enzyme level, however, was raised in both patients. It was concluded that the patient who was exposed to talc in the rubber industry had a true talc pneumoconiosis. The other patient, who was exposed to cosmetic talcum powder, suffered from chronic sarcoidosis with talc deposition in the lungs, since an enlarged axillar lymph node containing granulomatous inflammation was discovered after two years' follow up. These cases show that it may be extremely difficult to differentiate between chronic sarcoidosis and talc pneumoconiosis even after careful clinical and histological analysis. Images PMID:6691939

Plasma cell cheilitis, also known as plasma cell orificial mucositis is a benign inflammatory condition clinically characterized by erythematous plaque on lips that may be ulcerated. Histopathologically it is characterized by dense plasma cell infiltrates in a band-like pattern in dermis, which corresponds to Zoon's plasma cell balanitis. On the other hand, granulomatous cheilitis, as a part of orofacial granulomatosis, manifests as sudden diffuse or nodular swelling involving lip and cheek. Initial swelling is soft to firm, but with recurrent episodes swelling gradually become firm rubbery in consistency. We hereby report a case of cheilitis in a 52-year-old man with diffuse swelling involving lower lip, which clinically resembles granulomatous cheilitis, but histopathological examination showed diffuse infiltrate of plasma cells predominantly in upper and mid-dermis.

Objective Idiopathic granulomatous mastitis is a breast disease without a definitive etiology. There are no definitive classifications, scoring systems or certitudes. The aim of this study is to define the factors related to the recurrence and design a scoring system. Material and Methods Patients who were admitted to the general surgery department with symptoms of granulomatous mastitis were evaluated by ultrasonography and underwent antibiotic therapy. Granulomatous mastitis is diagnosed by core biopsy and treated with steroid therapy. Patients without improvement underwent surgery and were included in the study. In total, 53 patients were included in the study. There were 8 recurrent cases. Factors related with recurrences were defined. Results Number of births over 2, duration of lactation more than 18 months, body mass index greater than 31, having fistula in physical examination, abscess collection in ultrasonographic examination, and luminal inflammation score over 2 were scored as 1. Severity score in recurrent cases were 5.1±0.6 whereas 1.9±1.0 in nonrecurrent cases. Conclusion Granulomatous mastitis score is a tool targeted at predicting the risk of recurrences. The patients with these factors are more prone for recurrences. PMID:29774320

Granulomatous dermatitis is a distinctive histopathologic cutaneous reaction pattern against various infectious and noninfectious agents. Cytologically, granulomatous dermatitis shows granulomas and multinucleated giant cells. Various etiologic agents of granulomatous diseases can also be identified. We aimed to investigate Tzanck smear findings in granulomatous skin diseases. Patients who had granulomas and/or multinucleated giant cells of Langhans, foreign body- and/or Touton type in Tzanck smear tests were included in the study. In these patients, Tzanck preparations were then further evaluated for additional cytologic findings. Samples stained with May-Grünwald-Giemsa stain were evaluated by the same dermatologist throughout the study. In some patients, methylene blue, Gram and/or Erlich-Ziehl-Nielsen stains were also performed. In all of the study cases, the final diagnosis was established after the evaluation of clinical and laboratory findings (including, when appropriate, potassium hydroxide examination; bacterial, leishmanial, and fungal cultures; histopathology; tuberculosis and leishmania polymerase chain reaction). We also calculated the sensitivity and specificity of the Leishman-Donovan body for cutaneous leishmaniasis. Over a 2-year period, 94 of 950 patients (9.9%) in whom Tzanck smear tests were performed had cytologic findings consistent with a granulomatous reaction. In 74 (78.7%) and 20 (21.3%) patients, the granulomatous reaction was due to infectious and noninfectious causes, respectively. Infectious causes included cutaneous leishmaniasis in 65 patients (87.8%), candidal granuloma in two patients, botyromycosis in two patients, and aspergillosis, blastomycosis, mucormycosis, leprosy, and cutaneous tuberculosis in one patient each. In 58 of 74 patients (78.4%) with infectious granulomatous dermatitis, the causes of the granulomas were identified. Noninfectious granulomatous reactions were due to granuloma annulare in 7 patients, sarcoidosis

Granulomatous Mastitis in a Transgender Patient

Granulomatous mastitis is a rare and benign inflammatory condition of the breast most commonly affecting women of child-bearing age as well as patients on oral contraceptives. This condition is important to identify due to its diagnostic mimicry of malicious entities such as breast carcinoma. Clinical and radiological findings are nonspecific and may overlap with breast carcinomas, thus pathologic confirmation is often necessary for definitive diagnosis. Although cases of granulomatous mastitis have been described in cisgender females, there have been no reported cases in the transgender patient, a growing patient population with few imaging guidelines. Transgender patients are at risk of developing this breast entity due to the use of long-term hormone treatments or presence of residual breast tissue. A trial of antibiotics or steroids may be administered. However, surgical treatment is often necessary in recurrent or refractory cases. PMID:28580069

Background Idiopathic granulomatous mastitis is an uncommon, benign entity with a diagnosis of exclusion. The typical clinical presentation of idiopathic granulomatous mastitis often mimics infection or malignancy. As a result, histopathological confirmation of idiopathic granulomatous mastitis combined with exclusion of infection, malignancy and other causes of granulomatous disease is absolutely necessary. Case Presentation We present a case of a young woman with idiopathic granulomatous mastitis, initially mistaken for mastitis as well as breast carcinoma, and successfully treated with a course of corticosteroids. Conclusion There is no clear clinical consensus regarding the ideal therapeutic management of idiopathic granulomatous mastitis. Treatment options include expectant management with spontaneous remission, corticosteroid therapy, immunosuppressive agents and extensive surgery for refractory cases. PMID:17662130

Sarcoidosis affects multiple organs including lung, heart and kidney. Sarcoidosis causes hypercalcemia, hypergammaglobulinemia, and rarely, granulomatous interstitial nephritis, resulting in renal stromal damage. Granulomatous interstitial nephritis is characterized as interstitial nephritis with noncaseating epithelioid granulomas. Diagnosing granulomatous interstitial nephritis before patient's death is challenging; hence, only few cases proven by renal biopsy have been reported till date. We present a case of acute kidney injury caused by granulomatous interstitial nephritis as a renal manifestation of sarcoidosis proven by renal biopsy, which can be confirmed by 18 F-fluorodeoxyglucose positron emission tomography/computed tomography. Glucocorticoid therapy was helpful for improving and maintaining her renal function over a 6-year period.

A 77-year-old female patient with a medical history significant for hypertension and epilepsy presented with right breast pain of 6-months duration. Examination revealed a hard sub-areola tender mass with irregular borders associated with mild right nipple retraction. Mammography showed a 2.2 x 2.4 cm stellate mass of the right breast. Ultrasound-guided core biopsies of the tumour were performed. Pathological examination revealed a grade II infiltrating ductal carcinoma. The patient underwent right radical mastectomy with homolateral axillary lymphadenectomy. Histological examination of the surgical specimen revealed grade II infiltrating ductal carcinoma concomitant with granulomatous lobular mastitis. To the best of our knowledge, the coexistence of granulomatous lobular mastitis and ductal carcinoma has been described only twice in the English language literature. The theory that chronic inflammation leads to cancer is well documented. Whether our patient had developed cancer from granulomatous lobular mastitis or otherwise is a matter of debate until more cases are encountered and more research is done in the area of breast cancer pathogenesis with regards to it arising from granulomatous lobular mastitis.

Granulomatous slack skin is a very rare subtype of T-cell cutaneous lymphoma, characterized by the slow development of cutaneous sagging, especially on flexural areas. Its behavior is indolent and the treatment, in the majority of cases, disappointing. We report a 54-year-old black patient with granulomatous slack skin, who at the beginning of the investigation showed intense xeroderma and generalized lymph node enlargement. The diagnosis was established based on histopathologic findings long before the disease's characteristic clinical presentation appeared. During the twelve years of follow-up, the clinical manifestation evolved to marked skin looseness, most predominant in flexural regions, illustrating the clinical hallmark of granulomatous slack skin, long after first histological abnormalities were observed.

Granulomatous slack skin syndrome is a rare variant of cutaneous T-cell lymphoma (mycosis fungoides). It is characterized clinically by redundant skin folds, which show a predilection towards flexural areas such as the axilla and the groin. Histologically, it shows a granulomatous T-cell infiltrate and loss of elastic tissue. It has an indolent but progressive course; and is usually refractory to treatment. We report a unique case of slack skin syndrome, sparing the classical sites with rapid and unusual involvement of non-intertriginous areas.

Granulomatous reactions were immunologically induced in guinea pigs by several procedures, including intravenous injections of Bacille Calmette Gúerin (BCG) into animals immunized with complete Freund's Adjuvant and an intravenous injection of agarose beads linked to a specific antigen (dinitrophenylated bovine serum albumin) into immune animals. The tissue extracts obtained from lungs at various stages of granuloma formation were examined for macrophage migration inhibition (MIF) activity. The activity was found in a high incidence during the early stages of the granulomatous response. In contrast, MIF activity could be detected only rarely in granulomatous spleens and not in granulomatous livers. Chemotactic factor activity and mitogenic factor activity were only sporadically detectable. The MIF activity was associated with fractions showing chemical heterogeneity. One fraction was physicochemically indistinguishable from conventional lymphocyte-derived MIF; the other was a substance of large molecular weight. These results demonstrate the presence of biologically active mediators in immune granulomas, which may be related to early events involved in the induction or enhancement of such reactions.

Idiopathic granulomatous mastitis (IGM) is an uncommon breast disease often mistaken for breast infection or abscess. We present a case of IGM diagnosed after prolonged ineffective treatment of presumed infectious mastitis with abscess. Once the diagnosis was made with biopsy and further evaluation to exclude other causes of granulomatous disease, sinus tract debridement and closure by secondary intent resulted in resolution of symptoms in our patient. Many cases of IGM require immunosuppression with steroids, methotrexate or extensive surgery. To prevent morbidity, IGM should be considered in the differential diagnosis when presumed infectious mastitis with breast abscess does not respond to usual treatment.

Granulomatous inflammation of pulmonary squamous cell carcinoma: a rare phenomenon.

PubMed

Tajima, Shogo; Koda, Kenji

2015-01-01

Some neoplasms are associated with granulomatous inflammation. Granuloma formation in tumor tissue is caused by the cytokines derived from either the main tumor or other cells surrounding the tumor. In other instances, granulomatous inflammation is observed in the lymph nodes draining a tumor. This has been recognized as a sarcoid-like reaction. Herein, we report of a 75-year-old man with pulmonary squamous cell carcinoma (SCC), where granulomatous inflammation was observed extensively at the primary site. The carcinoma seemed to partly regress. In the regressing area, tumor cell debris was surrounded by granuloma. In contrast, no granuloma was identified in the dissected regional lymph nodes. To the best of our knowledge, such a case of SCC had not been described thus far. More case studies are required to determine whether tumor-related granuloma is the main cause of regression or whether it is just a secondary phenomenon caused by the attack and destruction of the tumor by lymphocytes.

Using genes to triangulate the pathophysiology of granulomatous autoinflammatory disease: NOD2, PLCG2 and LACC1.

PubMed

Szymanski, Ann Marie; Ombrello, Michael J

2018-04-25

The intersection of granulomatosis and autoinflammatory disease is a rare occurrence that can be generally subdivided into purely granulomatous phenotypes and disease spectra that are inclusive of granulomatous features. NOD2 (nucleotide-binding oligomerization domain-containing protein 2)-related disease, which includes Blau syndrome and early-onset sarcoidosis, is the prototypic example of granulomatous inflammation in the context of monogenic autoinflammation. Granulomatous inflammation has also been observed in two related autoinflammatory diseases caused by mutations in PLCG2 (phospholipase Cγ2). More recently, mutations in LACC1 (laccase domain-containing protein 1) have been identified as the cause of a monogenic form of systemic juvenile idiopathic arthritis, which does not itself manifest granulomatous inflammation, but the same LACC1 mutations have also been shown to cause an early-onset, familial form of a well-known granulomatous condition, Crohn's disease (CD). Rare genetic variants of PLCG2 have also been shown to cause a monogenic form of CD, and moreover common variants of all three of these genes have been implicated in polygenic forms of CD. Additionally, common variants of NOD2 and LACC1 have been implicated in susceptibility to leprosy, a granulomatous infection. Although no specific mechanistic link exists between these three genes, they form an intriguing web of susceptibility to both monogenic and polygenic autoinflammatory and granulomatous phenotypes.

The role of protease activation of inflammation in allergic respiratory diseases.

PubMed

Reed, Charles E; Kita, Hirohito

2004-11-01

Extracellular endogenous proteases, as well as exogenous proteases from mites and molds, react with cell-surface receptors in the airways to generate leukocyte infiltration and to amplify the response to allergens. Stimulation leads to increased intracellular Ca ++ and gene transcription. The most thoroughly investigated receptors, protease-activated receptors (PARs), are 7-transmembrane proteins coupled to G proteins. PARs are widely distributed on the cells of the airways, where they contribute to the inflammation characteristic of allergic diseases. PAR stimulation of epithelial cells opens tight junctions, causes desquamation, and produces cytokines, chemokines, and growth factors. They degranulate eosinophils and mast cells. Proteases contract bronchial smooth muscle and cause it to proliferate. PARs also promote maturation, proliferation, and collagen production of fibroblast precursors and mature fibroblasts. PAR-2, apparently the most important of the 4 PARs that have been characterized, is increased on the epithelium of patients with asthma. Trypsin, a product of injured epithelial cells, and mast cell tryptase are potent activators of PAR-2. Mast cell chymase activates PAR-1. Proteases from mites and molds appear to act through similar receptors. They amplify IgE production to allergens, degranulate eosinophils, and can generate inflammation, even in the absence of IgE. Proteases produced by Aspergillus species to support its growth are presumably responsible for the exuberant IgE, IgG, and granulomatous response of allergic bronchopulmonary aspergillosis. Similar proteases from molds germinating on the respiratory mucosa have been recently been implicated in the pathogenesis of chronic hyperplastic rhinitis and polyps and, by extension, of intrinsic asthma. Finally, proteases from mites and fungi growing in damp, water-damaged buildings might be the basis for the increased prevalence in these buildings of rhinitis, asthma, and other respiratory diseases

Introduction Idiopathic granulomatous lobular mastitis (IGLM) is an inflammatory disease of the breast with an obscure etiology. It occurs mainly in women of reproductive age, and the lesion mimics carcinoma of the breast both clinically and radiologically Case Presentation We present the case of a 29-year-old female who visited our hospital in Kancheepuram, Tamil Nadu, with a 4 × 3 cm lump in the upper outer quadrant of her left breast. The clinical and radiological findings were indicative of a malignant lesion; however, fine-needle aspiration cytology (FNAC) revealed features of granulomatous mastitis, and the subsequent histology of the excised lump confirmed the diagnosis of IGLM. Conclusions IGLM should be considered as one of the differential diagnoses when granulomas are encountered in breast FNAC and biopsy. A definitive diagnosis of IGLM can be made by identifying its characteristic histomorphology and ruling out other causes for granulomatous inflammation. An exact diagnosis is essential since the treatment for different granulomatous conditions of the breast varies. PMID:27437133

Previous studies demonstrated that SAA staining of sarcoidosis granulomas was qualitatively and quantitatively different from other granulomatous diseases. These data suggest that positive SAA staining of granulomatous tissue may have adequate specificity to establish a diagnosis of sarcoidosis. Our objective was to determine the diagnostic specificity of SAA staining for sarcoidosis relative to other granulomatous disorders. Pathological specimens demonstrating granulomatous inflammation were retrospectively identified at one institution, plus 4 specimens were obtained from New York City firefighters with biopsy-confirmed World Trade Center "sarcoidosis-like" pulmonary disease. Specimens were analyzed if specific diagnoses related to the granulomatous inflammation were confirmed through medical record review. SAA staining was performed using previously developed methods. Two pathologists, blinded to each other and the diagnoses, determined if the stained material was SAA positive or negative. Discordant results were adjudicated by the two pathologists. 106 specimens were analyzed from 100 patients, with 36 biopsies (34%) from sarcoidosis tissues and 70 (66%) from other granulomatous disorders. The Cohen Kappa correlation between the two pathologists for SAA staining positivity was excellent (0.85, 0.73-0.98). The overall specificity of SAA staining for the diagnosis of sarcoidosis was 84% (59/70). The sensitivity was 44% (16/36). Although SAA staining of various granulomatous tissues was fairly specific for the diagnosis of sarcoidosis, the specificity was inadequate for SAA staining to be used as a diagnostic test for sarcoidosis in isolation. These data suggest that SAA production may not be a universal mechanism in the development of sarcoidosis. Copyright © 2017 Elsevier Ltd. All rights reserved.

Although granulomatous lobular mastitis is associated with gram-positive bacilli such as Corynebacterium, this association is not well known. We report 3 cases of mastitis caused by gram-positive bacilli. All 3 abscesses were suppurative with distinct enlarged cystic spaces in which rare gram-positive bacilli were identified. Two cases were also granulomatous. Cultures in all 3 cases were negative. All 3 patients recovered after biopsy and tetracycline-based therapy. Infection in the breast by gram-positive bacilli is associated with a distinct histologic pattern, including cystic spaces in the setting of neutrophilic/granulomatous inflammation that can be recognized and should prompt careful search for the organism within enlarged vacuoles.

Granulomatous lobular mastitis is a rare chronic inflammatory disease of the breast. The differential diagnosis with malign breast disease is often not easy. In most cases a surgical biopsy is needed for correct diagnosis. Idiopathic granulomatous mastitis is an exclusion diagnosis, based on the demonstration of a characteristic histological pattern, combined with the exclusion of other possible causes of granulomatous breast lesions. There is still no generally accepted optimal treatment. If surgery forms part of the treatment, a conservative approach seems to be adequate in most cases. Another option is a long-term steroid treatment. It is mandatory to exclude infectious causes of granulomatous mastitis before corticoid therapy is started.

Granulomatous mastitis (GM) is an uncommon benign breast lesion. Diagnosis is a matter of exclusion from other inflammatory, infectious and granulomatous aetiologies. Here, we presented an atypical GM case, which had clinical and radiologic features overlapping with inflammatory breast cancer (IBC). The disease had multiple recurrences. The patient is a 40-year-old Caucasian woman with a sudden onset of left breast swelling accompanied by diffuse skin redness, especially of the subareolar region and malodorous yellow nipple discharge from the left nipple. The disease progressed on antibiotic treatment and recurred after local resection. A similar lesion developed even after bilateral mastectomy. GM may show clinical/radiologic features suggestive of IBC. Multiple recurrences can be occasionally encountered. GM after recurrence could be much more alarming clinically. Pathology confirmation is the key for accurate diagnosis and a multidisciplinary approach is important to rule out IBC. PMID:22715267

Background: Mastitis is an inflammatory disorder in breast tissues due to bacterial factors, mycobacterial infections or autoimmune diseases. Idiopathic granulomatous mastitis (IGM) is a form of mastitis which may be affected by systematic diseases such as sarcoidosis, and infectious causes such as mycobacterium and fungus. This study evaluates the efficacy of medical therapy with a combination of corticosteroid and Azithromycin in patients with IGM. Materials and Methods: This study is a clinical trial research carried out in Alzahra Hospital (Isfahan, Iran) in 2013 on granulomatous mastitis patients. It was administered 250 mg of Azithromycin per 12 hour and 60 mg of Prednisolone per day within 2 weeks. Next, they took 40 mg/day within 8 weeks, and this dosage was tapered during 6 months and the patients clinically and radiologically followed up. The studied patients were examined within 1 week, 2 weeks, 1 month, 3 months, and 6 months, from the beginning of treatment. Results: This study investigated granulomatous mastitis patients in Alzahra hospital in 2013. The mean age of these patients was 33.6 ± 8.9, and their age range was 18–56 years old. Among 26 studied patients, 24 persons (92.3%) according to follow-up the patients by physical examination and sonography responded to treatment of corticosteroid and Azithromycin. The remaining (7.7%) underwent surgery. Treatment periods in case of drug use were respectively, 8.5 ± 0.71 months. Conclusion: Treatment with corticosteroid and Azithromycin is an effective and appropriate treatment for IGM. PMID:28217653

Vitamin D supplementation precipitating hypercalcemic crisis is often the first manifestation in patients with granulomatous disorders. We report our experience on patients presenting with hypercalcemic crisis due to granulomatous disorder and the role of Vitamin D supplementation in the precipitation of hypercalcemic crisis in them. The study included five patients with granulomatous disorders who presented with hypercalcemic crisis. All patients initially presented with nonspecific constitutional symptoms to other health-care centers to receive high-dose Vitamin D supplementation (60,000 U/week or 600,000 U intramuscular single dose). All of these patients presented with hypercalcemic crisis (serum calcium: 16.04 ± 0.3 mg/dl) to our centers after a period of 32.8 ± 9.62 days. Three patients were diagnosed to have sarcoidosis, and two were diagnosed to have tuberculosis. All five patients had parathyroid hormone-independent hypercalcemia with elevated serum 1,25-dihydroxy Vitamin D. Serum angiotensin-converting enzyme level was elevated in all the three patients with sarcoidosis. Fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography was performed in two patients with sarcoidosis which demonstrated diffusely increased tracer uptake in liver. In these two patients, liver biopsy confirmed the diagnosis. High-dose Vitamin D supplementation is most often the underlying cause of hypercalcemic crisis in patients with granulomatous disorders. Hence, high-dose Vitamin D supplementation should be used judiciously.

Abstract Objective: The butyrophilin-like 2 (BTNL2) G16071A gene polymorphism has been implicated in the susceptibility to granulomatous diseases, but the results were inconclusive. The objective of the current study was to precisely explore the relationship between BTNL2 G16071A gene polymorphism and granulomatous disease susceptibility by the meta-analysis including false-positive report probability (FPRP) test. Methods: A systematic literature search in the PubMed, Embase, and Wanfang databases, China National Knowledge Internet, and commercial Internet search engines was conducted to identify studies published up to April 1, 2016. The odds ratio (OR) with 95% confidence interval (CI) was used to assess the effect size. Statistical analysis was conducted using the STATA 12.0 software and FPRP test sheet. Results: In total, all 4324 cases and 4386 controls from 14 eligible studies were included in the current meta-analysis. By the overall meta-analysis, we found a significant association between BTNL2 G16071A gene polymorphism and granulomatous disease susceptibility (A vs G: OR = 1.25, 95% CI = 1.07–1.45, P = 0.005). The meta-regression analyses showed that a large proportion of the between-study heterogeneity was significantly attributed to the ethnicity (A vs G, P = 0.013) and the types of granulomatous diseases (A vs G, P = 0.002). By the subgroup meta-analysis, the BTNL2 G16071A gene polymorphism was associated with granulomatous disease susceptibility in Caucasians (A vs G: OR = 1.37, 95% CI = 1.18–1.58, P < 0.001). Moreover, a significant relationship between the BTNL2 G16071A gene polymorphism and sarcoidosis susceptibility (A vs G: OR = 1.52, 95% CI = 1.39–1.66, P < 0.001) was found. However, to avoid the “false-positive report,” we further investigated the significant associations observed in the present meta-analysis by the FPRP test. Interestingly, the results of FPRP test indicated that the BTNL2

Breastfeeding has been linked to a reduction in the prevalence of allergy and asthma. However, studies on this relationship vary in outcome, which may partly be related to differences in breast milk composition. In particular breast milk composition may differ between allergic and non-allergic mothers. Important components that may be involved are breast milk proteins, as these are known to regulate immune development in the newborn. The objective of this study was therefore to explore differences in the proteins of breast milk from 20 allergic and non-allergic mothers. The results from this comparison may then be used to generate hypotheses on proteins associated with allergy in their offspring. Milk samples from allergic and non-allergic mothers were obtained from the PIAMA project, a prospective birth cohort study on incidence, risk factors, and prevention of asthma and inhalant allergy. Non-targeted proteomics technology, based on liquid chromatography and mass spectrometry, was used to compare breast milk from allergic and non-allergic mothers. Nineteen proteins, out of a total of 364 proteins identified in both groups, differed significantly in concentration between the breast milk of allergic and non-allergic mothers. Protease inhibitors and apolipoproteins were present in much higher concentrations in breast milk of allergic than non-allergic mothers. These proteins have been suggested to be linked to allergy and asthma. The non-targeted milk proteomic analysis employed has provided new targets for future studies on the relation between breast milk composition and allergy.

In the limited number of Crohn disease cases involving the head and neck, there is a predilection for mucosal surfaces and rare reports of involvement in the postauricular region. To our knowledge, in all previously reported cases involving the head and neck, the patients had a known diagnosis of Crohn disease. This case describes a 10-year-old boy with a history of psoriasis and psoriasiform dermatitis who presented with bilateral chronic granulomatous otitis externa, obliteration of the external auditory canal, and fissuring, resulting in separation of the lobule from the preauricular skin.

Risk factors for asthma have been investigated in a large number of studies in adults and children, with little progress in the primary and secondary prevention of asthma. The aim of this investigation was to investigate risk factors associated with allergic and non-allergic asthma in adolescents. In this study, 959 schoolchildren (13-14 years old) answered a questionnaire and performed exhaled nitric oxide (NO) measurements. All children (n = 238) with reported asthma, asthma-related symptoms and/or increased NO levels were invited to a clinical follow-up which included a physician evaluation and skin-prick testing. Asthma was diagnosed in 96 adolescents, whereof half had allergic and half non-allergic asthma. Children with both allergic and non-allergic asthma had a significantly higher body mass index (BMI) (20.8 and 20.7 vs. 19.8 kg/m(2)) (p < 0.05) and a higher prevalence of parental asthma (30% and 32% vs. 16%) (p < 0.05). Early-life infection (otitis and croup) [adjusted odds ratio (OR) (95% confidence interval (CI)): 1.99 (1.02-3.88) and 2.80 (1.44-5.42), respectively], pets during the first year of life [2.17 (1.16-4.04)], window pane condensation [2.45 (1.11-5.40)] and unsatisfactory school cleaning [(2.50 (1.28-4.89)] was associated with non-allergic but not with allergic asthma. This study indicates the importance of distinguishing between subtypes of asthma when assessing the effect of different risk factors. While the risk of both allergic and non-allergic asthma increased with increasing BMI, associations between early-life and current environmental exposure were primarily found in relation to non-allergic asthma.

Neutrophil recruitment by allergens contribute to allergic sensitization and allergic inflammation.

To discuss the presence and role of neutrophils in asthma and allergic diseases, and outline the importance of pollen and cat dander-induced innate neutrophil recruitment in induction of allergic sensitization and allergic inflammation. Uncontrolled asthma is associated with elevated numbers of neutrophils, and levels of neutrophil-attracting chemokine IL-8 and IL-17 in bronchoalveolar lavage fluids. These parameters negatively correlate with lung function. Pollen allergens and cat dander recruit neutrophils to the airways in a toll-like receptor 4, myeloid differentiation protein-2, and chemokine (C-X-C motif) receptor (CXCR) 2-dependent manner. Repeated recruitment of activated neutrophils by these allergens facilitates allergic sensitization and airway inflammation. Inhibition of neutrophil recruitment with CXCR2 inhibitor, disruption of toll-like receptor 4, or small interfering RNA against myeloid differentiation protein-2 also inhibits allergic inflammation. The molecular mechanisms by which innately recruited neutrophils contribute to shifting the airway inflammatory response induced by allergens from neutrophilic to an eosinophilic-allergic is an area of active research. Recent studies have revealed that neutrophil recruitment is important in the development of allergic sensitization and inflammation. Inhibition of neutrophils recruitment may be a strategy to control allergic inflammation.

Idiopathic granulomatous lobular mastitis.

Idiopathic granulomatous lobular mastitis (IGLM) is a rare breast condition with prominent skin findings. It is typically seen in young parous women. Painful breast masses, draining sinuses, scarring, and breast atrophy are the main clinical manifestations. IGLM can resemble a variety of other inflammatory and neoplastic processes of the breast. It is thought to result from obstruction and rupture of breast lobules. Extravasated breast secretions then induce an inflammatory reaction. Corynebacteria have also been implicated in the pathogenesis. Treatment is surgical, but systemic corticosteroids, methotrexate, and antibiotics also play a role. © 2012 The International Society of Dermatology.

The breast infection by M tuberculosis is rare, when it occurs, clinical and histologically confused with other forms of granulomatous inflammation, making it essential to use other diagnostic methods also may be negative. We report a patient with fimica mastitis that originally was treated as idiopathic granulomatous mastitis with apparent satisfactory clinical response. However, frequent relapses forced to look for other etiologies. Fortunately, the PCR showed the cause and was managed with specific treatment with disappearance of the disease. Clinical suspicion should be in mind when faced with a case like ours.

We report a case of granulomatous slack skin, a rare and indolent subtype of mycosis fungoides. It affects mainly men between the third and fourth decades. It is characterized by hardened and erithematous plaques that mainly affect flexural areas and become pedunculated after some years. Histological examination shows a dense infiltrate of small atypical lymphocytes involving the dermis (and sometimes the subcutaneous tissue) associated with histiocytic and multinucleated giant cells containing lymphocytes and elastic fibers (lymphophagocytosis and elastophagocytosis, respectively). Patients affected by this entity can develop secondary lymphomas. There are several but little effective therapeutic modalities described. Despite the indolent behavior of granulomatous slack skin, its early recognition and continuous monitoring by a dermatologist becomes essential for its management and prevention of an unfavorable outcome.

First report of granulomatous mastitis associated with Sjögren’s syndrome

2013-01-01

Granulomatous mastitis is a rare and often considered as idiopathic disease. However, clinical examination and thorough diagnostic investigations have to be carried out in order to identify cases that are secondary to infections or systemic diseases since these forms may be cured with appropriate etiologic treatment. To the best of our knowledge, this report is the first to describe the association of granulomatous mastitis with Sjögren’s syndrome. We discuss the clinical, pathological and therapeutic implications of this association. PMID:24112140

The authors report on four patients aged over 50 with chronic myopathy suggestive of sporadic inclusion body myositis. They present progressive and selective weakness of the quadriceps femoris muscles. Asymmetrical and selective atrophy of the forearm muscles were noted in all, with more severe involvement of the flexors than the extensors. Biopsy revealed granulomatous myositis. Histological features of sporadic inclusion body myositis were lacking. Evidence for systemic sarcoidosis was found in one patient. Corticosteroid treatment was associated with a partial but significant improvement in two patients. Granulomatous myositis may mimic inclusion body myositis and may be steroid-responsive.

Idiopathic granulomatous mastitis: a mimicking disease in a pregnant woman: a case report

PubMed Central

2013-01-01

Background Idiopathic granulomatous mastitis is a rare, benign, inflammatory chronic condition of unclear etiology. This case is reported because it illustrates how idiopathic granulomatous mastitis can mimic other diseases, making it difficult to associate the presenting symptoms and the correct diagnosis; This disease is a challenge for clinicians to diagnose, manage and avoid iatrogenic complications, and requires consultation with experts in several specialties. Case presentation The patient was 30 years old, South-American, eleven weeks pregnant, and with an apparent infectious mastitis. She presented with progressive worsening of her breast symptoms and multiple negative laboratory tests. She suffered different side effects from several prescribed treatments and endured a prolonged recovery. The article emphasizes the need for ruling out common pathologies to arrive at the correct diagnosis such as bacterial and fungal infections; granulomatous conditions like tuberculosis and sarcoidosis; and inflammatory breast carcinoma. It also describes frequently used pharmacological and supplementary forms of treatment for patients with this condition. Conclusion Idiopathic granulomatous mastitis is a rare unusual condition of unknown etiology. Pathological confirmation is required for its diagnosis and optimal management is still unclear. The presentation and management of this case is intended to advance its awareness to physicians from different specialties. PMID:23497626

Background: Growing evidence suggests that pesticide use may contribute to respiratory symptoms. Objective: We evaluated the association of currently used pesticides with allergic and non-allergic wheeze among male farmers. Methods: Using the 2005–2010 interview data of the Agricultural Health Study, a prospective study of farmers in North Carolina and Iowa, we evaluated the association between allergic and non-allergic wheeze and self-reported use of 78 specific pesticides, reported by ≥ 1% of the 22,134 men interviewed. We used polytomous regression models adjusted for age, BMI, state, smoking, and current asthma, as well as for days applying pesticides and days driving diesel tractors. We defined allergic wheeze as reporting both wheeze and doctor-diagnosed hay fever (n = 1,310, 6%) and non-allergic wheeze as reporting wheeze but not hay fever (n = 3,939, 18%); men without wheeze were the referent. Results: In models evaluating current use of specific pesticides, 19 pesticides were significantly associated (p < 0.05) with allergic wheeze (18 positive, 1 negative) and 21 pesticides with non-allergic wheeze (19 positive, 2 negative); 11 pesticides were associated with both. Seven pesticides (herbicides: 2,4-D and simazine; insecticides: carbaryl, dimethoate, disulfoton, and zeta-cypermethrin; and fungicide pyraclostrobin) had significantly different associations for allergic and non-allergic wheeze. In exposure–response models with up to five exposure categories, we saw evidence of an exposure–response relationship for several pesticides including the commonly used herbicides 2,4-D and glyphosate, the insecticides permethrin and carbaryl, and the rodenticide warfarin. Conclusions: These results for farmers implicate several pesticides that are commonly used in agricultural and residential settings with adverse respiratory effects.

Non-caseating granulomatous pulmonary conditions resembling sarcoidosis secondary to industrial/occupation exposure to magnetite iron ore dusts have been rarely documented in the literature. This is a case report of a 58-year-old blast crew member involved in iron ore/magnetite mining who presented with a 12-month history of chronic dry cough. High-resolution computed tomography revealed bilateral interstitial opacities. Lung biopsy demonstrated sarcoid-like granulomatous inflammation. Oral corticosteroid treatment improved the cough. Radiological features did not resolve despite treatment and yet remained stable following no subsequent exposure to iron mining dust.

We aimed to investigate the role of surgical excision in treating granulomatous lobular mastitis. We performed a retrospective chart review of patients with granulomatous lobular mastitis treated from March 2008 to March 2014. We analyzed clinical features and therapeutic modalities and compared the patient outcomes based on treatment. During the study period, a total of 34 patients were diagnosed with granulomatous lobular mastitis and treated. Initial treatments included wide excision (18), oral steroids after incision and drainage (14), and antibiotic therapy (2). The patients receiving only antibiotic therapy showed no improvement after 1 month and wide excision was then performed. Wide excision resulted in nine case of delayed wound healing with fistula. These patients were treated with oral steroids for 1.5-5 months, with subsequent improvement. Overall, 11 out of 20 patients who had underwent wide excision showed improvement without additional treatment. Fourteen patients who had initially received oral steroids for 1 to 6 months (average, 2.8 months) after incision and drainage showed complete remission. During the median follow-up period with 45.5 months (range, 22-98 months), six patients (17.6%) experienced recurrence. Wide excision group experienced recurrence in five (25%) and steroid and drainage group experienced recurrence in one (7.1%). All six recurrences responded to additional steroid therapy for average 3.5 months. Most wide excision group left extensive breast scarring with deformation that was not in steroid and drainage group. Wide excision resulted high recurrence than steroid and drainage group and left extensive scarring. Steroid therapy with or without abscess drainage may be the first choice of treatment for majority cases with granulomatous lobular mastitis.

A palpable abnormality of the breast was found in three women, one aged 57 and two aged 41. The first two patients predominantly showed the characteristics of a purulent inflammation, and on mammogram the third patient appeared to have mastitis carcinomatosa. Histopathological investigation revealed a lobular, non-caseating granulomatous inflammation. They were treated with prednisone and the first and third patients also received azathioprine. After some time, the condition recurred in the contralateral breast in the second and third patients. Once again, medicinal treatment was given. When a palpable tumour of the breast is found the primary goal is to exclude malignancy. Granulomatous lobular mastitis is a rare and benign tumour of the breast that clinically mimics carcinoma. Often, conventional imaging does not lead to the diagnosis. A histological needle biopsy is the best way to reach a diagnosis. Immunosuppressive therapy is effective and is preferred over surgery.

Granulomatous lobular mastitis is a rare chronic inflammatory disease of the breast. Clinical and radiological features may mimic breast carcinoma. Since this entity was first described, several clinical and pathologic features of the disease have been reported, but diagnostic features and treatment alternatives are still unclear. The purpose of this study is to evaluate diagnostic difficulties and discuss the outcome of surgical treatment in a series of 21 patients with granulomatous lobular mastitis. A retrospective review of 21 patients with histologically confirmed granulomatous lobular mastitis treated in our center between January 1995 and May 2005 was analyzed to identify issues in the diagnosis and treatment of this rare condition. The most common presenting symptoms were a mass in the breast and pain. Four patients had no significant mammographic findings (MMG), but on ultrasound (US), 2 had irregular hypoechoic mass, and 2 hypoechoic nodular structures had abnormalities-one parenchymal distortion and 1 mass formation in 2 of these 4 patients' magnetic resonance imaging (MRI). In recurrent cases, limited excision under local anesthesia was performed, as the clinical examination suggested carcinoma. Although some findings on MMG and US are suggestive of benign breast disease, these modalities do not rule out malignancy. MRI may be helpful in patients who do not have significant pathology at MMG or US. Fine-needle aspiration cytology may be useful in some cases but diagnosis is potentially difficult because of its cytologic characteristics. Wide excision, particularly under general anesthesia, can be therapeutic as well as useful in providing an exact diagnosis.

There is no convincing evidence as yet for a key role of immunological processes in the pathogenesis of unspecific colitis. However clinical findings as well as immunological data do support the hypothesis that immune reactions are involved primarily or secondarily in the pathogenesis and the clinical course of ulcerative colitis and granulomatous colitis. In such patients a specific adaptation of humoral and cell-bound immune reactions against antigenic material from the colon and other tissues has been found in peripheral blood, lymphatic tissue and bowel wall. In this context it seems to be especially noteworthy, that lymphocytes taken from patients with colitis lead to disintegration of colon epithelial cells in vitro. This cytotoxic effect of the lymphocytes is lost after colectomy or remission of the disease. Ulcerative and granulomatous colitis do have many clinical and immunological peculiarities in common. This makes one think, that possibly the same noxious factors induce differential local reactions because of different hereditary disposition.

Juvenile sterile granulomatous dermatitis and lymphadenitis is a rare immune-mediated skin disease in young dogs. History, signalment, diagnostics, treatment, and outcome in 10 dogs are described. The age ranged from 8 - 36 weeks. The lymph nodes were enlarged in all dogs, especially the mandibular and prescapular lymph nodes. Systemic signs including fever were present in 8 dogs. Seven dogs suffered from blepharitis and painful edema of the muzzle with hemorrhagic discharge, pustules and papules. Cytology of pustules and lymph node aspirates revealed a pyogranulomatous inflammation. In 7 cases the diagnosis of juvenile sterile granulomatous dermatitis and lymphadenitis was confirmed by histology. Nine dogs were treated with prednisolone (0.5 - 1.25 mg/kg BID), H2-receptor antagonists and analgetics; all dogs were treated with antibiotics. Four dogs were treated with eye ointment containing antibiotics and glucocorticoids. The prednisolone dosage was tapered over 3 - 8 weeks. One dog had a relapse.

In this article, we discuss the link between the environment, DNA methylation and allergic disease, as well as questions of causality inherent to analyses of DNA methylation. From the practical side, we describe characteristics of allergic phenotypes and contrast different epidemiologic study designs used in epigenetic research. We examine methodological considerations, how best to conduct preprocessing and analysis of DNA methylation data sets, and the latest methods, technologies and discoveries in this rapidly advancing field. DNA methylation and other epigenetic marks are firmly entwined with allergic disease, a link that may hold the basis for future allergic disease diagnosis and treatment. PMID:24283882

Canine granulomatous hepatitis is an uncommon morphologic diagnosis that has been associated with a variety of diseases, including a number of systemic infectious etiologies. Formalin-fixed, paraffin-embedded (FFPE) tissues are typically the only source of liver tissue remaining for additional testing for the presence of infectious disease within granulomas. It is unclear if the more common infectious culprits of granulomatous hepatitis can be identified from such specimens. The aim of the current study was to retrospectively investigate archival FFPE liver tissue from dogs with granulomatous hepatitis for the presence of infectious agents. Semiquantitative analysis of copper accumulation in liver specimens was also performed. Medical records were examined for recorded evidence of systemic infectious disease diagnosis. Formalin-fixed, paraffin-embedded liver was prospectively evaluated for infectious agents via differential staining techniques (n = 13), eubacterial fluorescent in situ hybridization (n = 11), and Bartonella polymerase chain reaction assays (n = 15). An infectious cause of granulomatous hepatitis was not identified within liver tissue from any dog using these diagnostic methodologies. Six out of 25 (24%) dogs were diagnosed with concurrent systemic or localized bacterial infections at the time of presentation. Nine out of 17 (53%) dogs had excessive hepatic copper accumulation when evaluated by a semiquantitative histologic grading scheme or quantitative copper analysis. As definitive infectious causes of granulomatous hepatitis were not identified within archival liver biopsy samples, it was concluded that investigation of infectious etiologies within FFPE liver specimens using these diagnostic approaches may be of low yield.

Trehalose 6'6-dimycolate (TDM) is the most abundant glycolipid on the cell wall of Mycobacterium tuberculosis (MTB). TDM is capable of inducing granulomatous pathology in mouse models that resembles those induced by MTB infection. Using the acute TDM model, this work investigates the effect of recombinant human and mouse lactoferrin to reduce granulomatous pathology. C57BL/6 mice were injected intravenously with TDM at a dose of 25 μg·mouse -1 . At day 4 and 6, recombinant human or mouse lactoferrin (1 mg·(100 μL) -1 ·mouse -1 ) were delivered by gavage. At day 7 after TDM injection, mice were evaluated for lung pathology, cytokine production, and leukocyte populations. Mice given human or mouse lactoferrin had reduced production of IL-12p40 in their lungs. Mouse lactoferrin increased IL-6 and KC (CXCL1) in lung tissue. Increased numbers of macrophages were observed in TDM-injected mice given human or mouse lactoferrin. Granulomatous pathology, composed of mainly migrated leukocytes, was visually reduced in mice that received human or mouse lactoferrin. Quantitation of granulomatous pathology demonstrated a significant decrease in mice given human or mouse lactoferrin compared with TDM control mice. This report is the first to directly compare the immune modulatory effects of both heterologous recombinant human and homologous mouse lactoferrin on the development of TDM-induced granulomas.

Allergic rhinitis

Allergic rhinitis is a common disorder that is strongly linked to asthma and conjunctivitis. It is usually a long-standing condition that often goes undetected in the primary-care setting. The classic symptoms of the disorder are nasal congestion, nasal itch, rhinorrhea and sneezing. A thorough history, physical examination and allergen skin testing are important for establishing the diagnosis of allergic rhinitis. Second-generation oral antihistamines and intranasal corticosteroids are the mainstay of treatment. Allergen immunotherapy is an effective immune-modulating treatment that should be recommended if pharmacologic therapy for allergic rhinitis is not effective or is not tolerated. This article provides an overview of the pathophysiology, diagnosis, and appropriate management of this disorder. PMID:22166009

Granulomatous mastitis is a rare condition of the breast that can mimic a carcinoma. There are characteristic histological features, the most important of which is a predominantly lobular inflammatory process. It must be differentiated from known causes of granulomatous inflammation, such as tuberculosis. In the present paper, the clinical and pathological features of 16 patients with granulomatous mastitis seen over a 3-year period in the University Hospital, Kuala Lumpur, are described. A clinical suspicion of malignancy was present in 10 cases. One of the patients was nulliparous. One had an associated hyperprolactinaemia, while two had systemic lupus erythromatosis. One of the patients was pregnant at the time of presentation. Four patients had localized lumps excised, five were treated conservatively because the lesion was too extensive to resect, and seven patients required drainage procedures for abscess formation. Awareness of this condition is important because it mimics a carcinoma, and surgery may not be the best treatment for recurrent disease.

The regulatory role of suppressor of cytokine signaling 1 (SOCS1) in inflammation has been reported. However, its role in allergic inflammation has not been previously reported. SOCS1 mediated in vitro and in vivo allergic inflammation. Histone deacetylase-3 (HDAC3), a mediator of allergic inflammation, interacted with SOCS1, and miR-384 inhibitor, a positive regulator of HDAC3, induced features of allergic inflammation in an SOCS1-dependent manner. miRNA array analysis showed that the expression of miR-122 was decreased by antigen-stimulation. TargetScan analysis predicted the binding of miR-122 to the 3′-UTR of SOCS1. miR-122 inhibitor induced in vitro and in vivo allergic features in SOCS1-dependent manner. SOCS1 was necessary for allergic inflammation-promoted enhanced tumorigenic and metastatic potential of cancer cells. SOCS1 and miR-122 regulated cellular interactions involving cancer cells, mast cells and macrophages during allergic inflammation. SOCS1 mimetic peptide, D-T-H-F-R-T-F-R-S-H-S-D-Y-R-R-I, inhibited in vitro and in vivo allergic inflammation, allergic inflammation-promoted enhanced tumorigenic and metastatic potential of cancer cells, and cellular interactions during allergic inflammation. Janus kinase 2 (JAK2) exhibited binding to SOCS1 mimetic peptide and mediated allergic inflammation. Transforming growth factor- Δ1 (TGF-Δ1) was decreased during allergic inflammation and showed an anti-allergic effect. SOCS1 and JAK2 regulated the production of anti-allergic TGF-Δ1. Taken together, our results show that miR-122-SOCS1 feedback loop can be employed as a target for the development of anti-allergic and anti-cancer drugs. PMID:28968979

Sarcoidosis is a multi-system disease characterized by the presence of non-caseating epithelioid granulomas in affected tissues, including skeletal muscle. These organized collections of immune cells have important pathophysiologic action including cytokine production leading to inflammation as well as enzymatic conversion of cholecalciferol to calcitriol via 1-α hydroxylase. There are limited reports of isolated granulomatous myositis causing hypercalcemia in pediatric patients. Our patient uniquely presented with symptoms from hypercalcemia and renal insufficiency caused by an overwhelming burden of granulomatous myositis in her lower extremities, but was otherwise asymptomatic. A 16 year old Caucasian female presented with protracted symptoms of fatigue, nausea and prominent weight loss with laboratory evidence of hypercalcemia and renal insufficiency. She lacked clinical and physical findings of arthritis, weakness, rash, uveitis, fever, lymphadenopathy or respiratory symptoms. After extensive negative investigations, re-examination yielded subtle soft tissue changes in her lower extremities, with striking MRI findings of extensive myositis without correlative weakness or serum enzyme elevation. Biopsy showed the presence of non-caseating epithelioid granulomas and calcium oxalate crystals. The patient responded well to prednisone and methotrexate but relapsed with weaning of steroids. She reachieved remission with addition of adalimumab. Sarcoidosis should be considered in patients presenting with symptomatic hypercalcemia with no apparent causes and negative routine workup. The absences of decreased muscle strength or elevated muscle enzymes do not preclude the diagnosis of granulomatous myositis.

A 28-year-old male patient presented with circumscribed erythematous loose skin masses, especially in the body folds and which had been relapsing for 4years. Skin biopsy showed a loss of elastic fibers and an atypical granulomatous T-cell infiltrate with epidermotropism, enabling a diagnosis of GSS to be made. A biopsy of a retroperitoneal lymphadenopathy showed testicular seminoma metastasis. Patients suffering from GSS have a statistically higher risk of developing a second primary cancer, especially Hodgkin's lymphoma. The association found between GSS and a lymphoproliferative malignancy requires long-term follow-up and determines the patient's prognosis. It is not possible to prove a formal link between GSS and testicular seminoma. However, this case illustrates the value of screening for a second cancer, particularly where extra-cutaneous lesions appear during GSS treatment. Lymph node biopsy should be performed routinely in the event of GSS with possible lymph node involvement. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Herpes simplex virus encephalitis can manifest as a range of clinical presentations including classic adult, neonatal, and biphasic chronic-granulomatous herpes encephalitis. We report an infant with granulomatous herpes simplex virus type 2 encephalitis with a subacute course and multicystic encephalopathy. A 2-month-old girl presented with lethargy and hypothermia. Computed tomography scan of the head showed multicystic encephalopathy and calcifications. Cerebrospinal fluid analysis by polymerase chain reaction testing for herpes simplex virus 1 and 2, enterovirus, and cytomegalovirus was negative. Normal cerebrospinal fluid interferon-α levels argued against Aicardi-Goutières syndrome. The patient died 2 weeks after presentation. At autopsy, multicystic encephalopathy was confirmed with bilateral gliosis, granulomatous inflammation with multinucleated giant cells, and calcifications. Bilateral healing necrotizing retinitis suggested a viral etiology, but retina and brain were free of viral inclusions and immunohistochemically negative for herpes simplex virus-2 and cytomegalovirus. However, polymerase chain reaction analysis showed herpes simplex virus-2 DNA in four cerebral paraffin blocks. Subsequent repeat testing of the initial cerebrospinal fluid sample using a different polymerase chain reaction assay was weakly positive for herpes simplex virus-2 DNA. Granulomatous herpes simplex virus encephalitis in infants can present with subacute course and result in multicystic encephalopathy with mineralization and minimal cerebrospinal fluid herpes simplex virus DNA load. Infectious etiologies should be carefully investigated in the differential diagnosis of multicystic encephalopathy with mineralization, in particular if multinucleated giant cells are present.

Dentogenous inflammatory diseases can lead to typical dermatological facial symptoms with formation of cutaneous sinuses. Partsch's chronic granulomatous inflammation can result from conducted inflammation of a nonvital tooth via a chronic apical inflammation. In this rare disease, the granulomatous tissue perforates the bone, channels through the overlying skin, and drains via cutaneous or oral sinuses. A frequent localization of the cutaneous sinus is the skin inferior to the body of the mandible, and it is caused by an inflammation of the lower molars. Treatment consists of identifying the responsible teeth and eliminating the focus of infection. Chronically progressive periradicular granuloma and/or radicular cysts can be present with impressive dermatological symptoms. Therefore, X-ray examinations are necessary to exclude possible dentogenic causes in cases of badly healing processes of the face or neck.

Idiopathic granulomatous mastitis (IGM) is a rare inflammatory condition of the breast. The etiology and treatments options of IGM remain controversial. Previous case reports have suggested that Corynebacterium sp., a gram-positive bacillus endogenous to the skin, may be associated with IGM. In the present report, we describe the first case of IGM with a positive culture for Corynebacterium sp. reported in the United States. PMID:21857740

Abstract Rationale: The simultaneous occurrence of pyoderma gangrenosum (PG) and chronic granulomatous disease (CGD) is uncommon and few cases have been reported worldwide. Patient concerns: PG is a rare, chronic, ulcerative, neutrophilic skin disease of unknown etiology that requires immunosuppressive treatment. CGD belongs to Primary Immune Deficiencies in which the main defect lies in an inability of the phagocytic cells to generate superoxide making patients susceptible to serious, potentially life-threatening bacterial and fungal infections. Diagnoses: In this manuscript, we present a case of ulcerative pyoderma gangrenosum in a 28-year-old man with recent diagnosis of chronic granulomatous disease during hospitalization for resistant pulmonary tuberculosis complicated with Aspergillus infection. Interventions: Second-line therapy with dapsone and intravenous immunoglobulin was initially administered but eventually corticosteroids were added to treatment because of disease progression and further ulceration. Outcomes: Patient's ulcers were gradually healed with no side effects. Lessons: Corticosteroids could be used under close monitoring for the treatment of PG in a patient with CGD, despite the increased risk for infections. PMID:28767612

A nestling Derbyan parrot (Psittacula derbiana) was presented with unusual subcutaneous swellings of the thigh regions, and poor growth. Histological examination revealed actinomycetous bacteria associated with multifocal systemic granulomas. The clinical and pathological findings of the case are presented, and some relevant aspects of actinomycetous bacterial infections in mammals and birds are discussed. Although granulomatous disease is encountered at times in avian species, the actinomycetous bacteria (Nocardia and Actinomyces spp.) have rarely been reported in association with multifocal granulomatous disease in birds.

Management of Allergic Rhinitis

Allergic rhinitis is the most common chronic childhood disease. Reduced quality of life is frequently caused by this IgE-mediated disease, including sleep disturbance with subsequent decreased school performance. Asthma and exercise-induced bronchospasm are commonly seen concurrently with allergic rhinitis, and poorly controlled allergic rhinitis negatively affects asthma outcomes. Nonsedating antihistamines or intranasal azelastine are effective agents to manage allergic rhinitis, often in combination with oral decongestants. For moderate to severe persistent disease, intranasal corticosteroids are the most effiective agents. Some patients require concomitant intranasal corticosteroids and nonsedating antihistamines for optimal management. Other available agents include leukotriene receptor antagonists, intranasal cromolyn, intranasal ipratropium, specific immunotherapy, and anti-IgE therapy. PMID:23118635

Granulomatous (lobular) mastitis is a rare inflammatory breast disease affecting parous reproductive-aged women. Once considered idiopathic, there is growing evidence of an association with corynebacteria infection, especially in the setting of a distinct histological pattern termed cystic neutrophilic granulomatous mastitis (CNGM). We describe 15 cases with histological features either confirming (n = 12) or suggesting (n = 3) CNGM, and concurrent microbiological evidence of Corynebacterium species. The organism was detected by culture or 16S rRNA gene sequencing of specimens obtained at surgery or fine needle aspiration. In seven cases, Gram-positive organisms were seen within vacuolated spaces. Speciation was performed in nine cases, with Corynebacterium kroppenstedtii subsequently identified. These cases provide further evidence in support of this association and in doing so highlight the importance of recognising these histological clues as well as the limitations of Gram stain and microbiological culture in detecting this previously under-recognised disease process.

A 41-yr-old multiparous woman presented with a discrete breast lump which proved histologically to be an example of granulomatous lobular mastitis. The clinical and histological features were similar to those noted in previous reports. Additional histological features in the present case were an intense mononuclear cell infiltration of lobular and ductal epithelium, associated with nuclear fragments morphologically suggestive of apoptosis. These appearances, which have not previously been described, are illustrated, together with the more classical features of the condition well demonstrated by the present case. The novel histological features noted here suggest that the development of granulomatous lobular mastitis may be at least in part immunologically mediated, and that the cellular infiltrates seen may be a manifestation of cell-mediated destruction of mammary epithelium.

Rhinitis is a symptomatic inflammatory disorder of the nose with different causes such as allergic, nonallergic, infectious, hormonal, drug induced, and occupational and from conditions such as sarcoidosis and necrotizing antineutrophil cytoplasmic antibodies positive (Wegener's) granulomatosis. Allergic rhinitis affects up to 40% of the population and results in nasal (ocular, soft palate, and inner ear) itching, congestion, sneezing, and clear rhinorrhea. Allergic rhinitis causes extranasal untoward effects including decreased quality of life, decreased sleep quality, obstructive sleep apnea, absenteeism from work and school, and impaired performance at work and school termed "presenteeism." The nasal mucosa is extremely vascular and changes in blood supply can lead to obstruction. Parasympathetic stimulation promotes an increase in nasal cavity resistance and nasal gland secretion. Sympathetic stimulation leads to vasoconstriction and consequent decrease in nasal cavity resistance. The nasal mucosa also contains noradrenergic noncholinergic system, but the contribution to clinical symptoms of neuropeptides such as substance P remains unclear. Management of allergic rhinitis combines allergen avoidance measures with pharmacotherapy, allergen immunotherapy, and education. Medications used for the treatment of allergic rhinitis can be administered intranasally or orally and include oral and intranasal H(1)-receptor antagonists (antihistamines), intranasal and systemic corticosteroids, intranasal anticholinergic agents, and leukotriene receptor antagonists. For intermittent mild allergic rhinitis, an oral or intranasal antihistamine is recommended. In individuals with persistent moderate/severe allergic rhinitis, an intranasal corticosteroid is preferred. When used in combination, an intranasal H(1)-receptor antagonist and a nasal steroid provide greater symptomatic relief than monotherapy. Allergen immunotherapy is the only disease-modifying intervention available.

The majority of tattoo reactions are affiliated to red pigmented areas and often suspected to be allergic in nature. A sizeable series of biopsies of such reactions has not previously been performed. The aim of this study was to type and grade epidermal and dermal changes in tattoo reactions to red/red nuances by microscopy and immunochemistry relevant for the assessment of a possible allergic pathomechanism. Skin biopsies were taken from red tattoo reactions, graded by conventional microscopy and stained for T and B-lymphocytes, Langerhans cells, macrophages and tumour necrosis factor (TNF)-α. The study included 19 biopsies from 19 patients. The culprit colours were red/pink (n = 15) and purple/bordeaux (n = 4). Interface dermatitis was clearly the lead pathology found in 78% of samples, overlapped with granulomatous (in 32%) and pseudolymphomatous reaction patterns (in 32%). Epidermal hyperkeratosis (in 89%) was common as was leakage of red pigment across the dermo-epidermal junction, with transepidermal elimination (in 28%). The dermal cellular infiltration was dominated by T-lymphocytes (in 100%), Langerhans cells (in 95%) and macrophages (in 100%). TNF-α was common. The predominant histological pattern of chronic tattoo reactions in red/red nuances is interface dermatitis. T-lymphocytes and Langerhans cells are increased suggesting an allergic pathomechanism. TNF-α may contribute to reactions. In many cases, overlapping reactive patterns were identified. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Like asthma and atopic dermatitis, allergic rhinitis is an allergic disease, but of the three, it is the only type I allergic disease. Allergic rhinitis includes pollinosis, which is intractable and reduces quality of life (QOL) when it becomes severe. A guideline is needed to understand allergic rhinitis and to use this knowledge to develop a treatment plan. In Japan, the first guideline was prepared after a symposium held by the Japanese Society of Allergology in 1993. The current 7th edition was published in 2013, and is widely used today. To incorporate evidence based medicine (EBM) introduced from abroad, the most recent collection of evidence/literature was supplemented to the Practical Guideline for the Management of Allergic Rhinitis in Japan 2013. The revised guideline includes assessment of diagnosis/treatment and prescriptions for children and pregnant women, for broad clinical applications. An evidence-based step-by-step strategy for treatment is also described. In addition, the QOL concept and cost benefit analyses are also addressed. Along with Allergic Rhinitis and its Impact of Asthma (ARIA), this guideline is widely used for various clinical purposes, such as measures for patients with sinusitis, childhood allergic rhinitis, oral allergy syndrome, and anaphylaxis and for pregnant women. A Q&A section regarding allergic rhinitis in Japan was added to the end of this guideline.

Purpose. The histological diagnosis of Mycobacterium tuberculosis (MTB) remains a diagnostic challenge despite different methods. Immunohistochemistry (IHC) not only could confirm granulomatous tissue involvement but also can demonstrate MTB antigen immunolocalization. This study tries to clarify the details of immunohistochemical staining for MTB with pAbBCG. Materials/Methods. Twenty-three confirmed TB granulomatous tissue samples were studied by Ziehl-Neelsen and immunohistochemistry (IHC) staining with pAbBCG. Samples were selected from the archive of the Department of Pathology, National Research Institute of Tuberculosis and Lung Disease, Tehran, Iran. Results. IHC staining was positive in all samples, whereas Ziehl-Neelsen was positive in 9 cases out of 23 (39.1%). Tissue types used were pleural tissue, lymph nodes, and lung tissue. IHC showed positive coarse granular cytoplasmic and round, fragmented bacillary staining. In this study, epithelioid cells clearly showed more positive staining at the periphery of the granuloma rather than the center of granuloma. There is also positive staining in endothelial cells, fibroblasts, plasma cells, lymphocytes, and macrophages outside the granuloma. Conclusion. Considering the criteria of positive immunohistochemical staining of TB granulomatous reactions, this stain not only highlights the presence of mycobacterial antigens for tissue diagnosis, but also could morphologically localize its distribution in different cells.

Bacille Calmette-Guerin intravesical treatment is the most effective treatment for reducing the recurrence of non-muscle-invasive urothelial carcinomas. This treatment can sometimes have side effects and serious complications. Granulomatous prostatitis is a common histological finding but it rarely has a clinical presentation. We report a case of a 75-year-old, type 2 diabetic, male patient who was diagnosed with urothelial in situ carcinoma, for which he began treatment with Bacille Calmette-Guerin instillations. Five years later the patient presented nocturia, pollakiuria, severe urgency, and intense and recurrent perineal pain associated with marked elevation of prostatic specific antigen. A prostatic biopsy was performed that showed a moderate to severe granulomatous prostatitis related to bacille Calmette-Guerin. The patient received full antituberculosis combination drugs with a favorable clinical response.

Sometimes, mastitis needs to be differentiated from carcinoma because of its association with induration and with ultrasound findings (such as low-echo lesions) that resemble those in carcinoma. The aim was to define this type of mastitis and to examine 18 cases to clarify its clinicopathological features. All cases were categorized into three types: non-specific mastitis with neutrophilic infiltration (n = 7); non-specific mastitis with lymphoplasmacytic infiltration (n = 9); and granulomatous lobular mastitis (n = 2). The three types of mastitis presented similar ultrasound findings and shared certain histological features including fibrosis and diffuse or lobulocentric inflammation. Granulomatous lobular mastitis showed specific clinicopathological features including lobulocentric inflammation with giant cells, diffuse IgG4+ plasma cells, and also a high level of serum IgG4. Granulomatous lobular mastitis could be categorized into IgG4-related and non-IgG4-related granulomatous lobular mastitis. IgG4 immunohistochemistry serum IgG4 might be useful for diagnosis of IgG4-related granulomatous lobular mastitis and could help to avoid overtreatment such as wide excision.

We report 12 cases of granulomatous lobular mastitis occurring in young women, between ages 30 and 47 years, diagnosed at King Faisal Specialist Hospital and Research Centre (KFSH&RC) from 1987 to 1995. The disease was unilateral in 10 cases, while there was a history of involvement of the contralateral breast in two patients. At the time of diagnosis, two patients were lactating, two were pregnant, and two were pregnant and lactating. Histopathological examination in all cases revealed centrilobular granulomas and microabscess formation. Immunohistochemical staining in seven cases for T and B cell markers showed a predominance of T cells in the infiltrate in all cases. The treatment comprised surgical removal of the mass, debridement and antibiotics in some of the cases. In one patient referred from another institution, mastectomy had been performed on the basis of an erroneous histopathologic diagnosis of carcinoma. Preoperative diagnosis was carcinoma in seven cases and benign disease in the remaining five cases. Follow-up of the patients was uneventful in all cases. Granulomatous lobular mastitis is a rare inflammatory disease of the breast, which may clinically and pathologically mimic carcinoma, sometimes leading to misdiagnosis resulting in unnecessary surgery.

The authors summarise the clinical notes and histological findings of 17 patients who had inflammatory changes in their breasts and in whom biopsies showed epithelioid granulation tissues with giant cells. Three separate histological tables have been prepared as well as a review of the literature. The paper shows that mixed granulomatous conditions exist, with the sites of the changes being both in the canals and in the lobules. This gives rise to a discussion about the separateness of the condition, which is presumed to be of an autoimmune origin. It is pointed out that there can be an infectious element present.

The current report describes granulomatous pneumonia due to Spirocerca lupi in 2 free-ranging maned wolves (Chrysocyon brachyurus). Both wolves had multiple, white, 1-1.5 cm in diameter, soft, encapsulated granulomas in the caudal lung lobes, which contained centrally placed parasites on cut sections. Microscopically, there was granulomatous inflammation with numerous intralesional sections of spirurid nematodes. Representative complete adult specimens of nematodes derived from these lesions were submitted for parasitological exam and identified as the spirurid S. lupi. To the authors' knowledge, there have been no published reports of S. lupi in maned wolves. © 2014 The Author(s).

Recent studies have shown that thymosin β4 (Tβ4) stimulates angiogenesis by inducing vascular endothelial growth factor (VEGF) expression and stabilizing hypoxia inducible factor-1α (HIF-1α) protein. Pulmonary tuberculosis (TB), a type of granulomatous disease, is accompanied by intense angiogenesis and VEGF levels have been reported to be elevated in serum or tissue inflamed by pulmonary tuberculosis. We investigated the expression of Tβ4 in granulomatous lung tissues at various stages of active pulmonary tuberculosis, and we also examined the expression patterns of VEGF and HIF-1α to compare their Tβ4 expression patterns in patients' tissues and in the tissue microarray of TB patients. Tβ4 was highly expressed in both granulomas and surrounding lymphocytes in nascent granulomatous lung tissue, but was expressed only surrounding tissues of necrotic or caseous necrotic regions. The expression pattern of HIF-1α was similar to that of Tβ4. VEGF was expressed in both granulomas and blood vessels surrounding granulomas. The expression pattern of VEGF co-localized with CD31 (platelet endothelial cell adhesion molecule, PECAM-1), a blood endothelial cell marker, and partially co-localized with Tβ4. However, the expression of Tβ4 did not co-localize with alveolar macrophages. Stained alveolar macrophages were present surrounding regions of granuloma highly expressing Tβ4. We also analyzed mRNA expression in the sputum of 10 normal and 19 pulmonary TB patients. Expression of Tβ4 was significantly higher in patients with pulmonary tuberculosis than in normal controls. These data suggest that Tβ4 is highly expressed in granulomatous lung tissue with active pulmonary TB and is associated with HIF-1α- and VEGF-mediated inflammation and angiogenesis. Furthermore, the expression of Tβ4 in the sputum of pulmonary tuberculosis patients can be used as a potential marker for diagnosis. Copyright © 2014 Elsevier Ltd. All rights reserved.

Facilitation of Allergic Sensitization and Allergic Airway Inflammation by Pollen-Induced Innate Neutrophil Recruitment.

Neutrophil recruitment is a hallmark of rapid innate immune responses. Exposure of airways of naive mice to pollens rapidly induces neutrophil recruitment. The innate mechanisms that regulate pollen-induced neutrophil recruitment and the contribution of this neutrophilic response to subsequent induction of allergic sensitization and inflammation need to be elucidated. Here we show that ragweed pollen extract (RWPE) challenge in naive mice induces C-X-C motif ligand (CXCL) chemokine synthesis, which stimulates chemokine (C-X-C motif) receptor 2 (CXCR2)-dependent recruitment of neutrophils into the airways. Deletion of Toll-like receptor 4 (TLR4) abolishes CXCL chemokine secretion and neutrophil recruitment induced by a single RWPE challenge and inhibits induction of allergic sensitization and airway inflammation after repeated exposures to RWPE. Forced induction of CXCL chemokine secretion and neutrophil recruitment in mice lacking TLR4 also reconstitutes the ability of multiple challenges of RWPE to induce allergic airway inflammation. Blocking RWPE-induced neutrophil recruitment in wild-type mice by administration of a CXCR2 inhibitor inhibits the ability of repeated exposures to RWPE to stimulate allergic sensitization and airway inflammation. Administration of neutrophils derived from naive donor mice into the airways of Tlr4 knockout recipient mice after each repeated RWPE challenge reconstitutes allergic sensitization and inflammation in these mice. Together these observations indicate that pollen-induced recruitment of neutrophils is TLR4 and CXCR2 dependent and that recruitment of neutrophils is a critical rate-limiting event that stimulates induction of allergic sensitization and airway inflammation. Inhibiting pollen-induced recruitment of neutrophils, such as by administration of CXCR2 antagonists, may be a novel strategy to prevent initiation of pollen-induced allergic airway inflammation.

BACKGROUND AND OBJECTIVES: The relationship between allergic diseases and internalizing disorders has not been well characterized with regard to multiple allergic diseases or longitudinal study. The objective of this study was to examine the association between multiple allergic diseases in early childhood with validated measures of internalizing disorders in the school-age years. METHODS: Children enrolled in the Cincinnati Childhood Allergy and Air Pollution Study underwent skin testing and examinations at ages 1, 2, 3, 4, and 7 years. At age 7, parents completed the Behavior Assessment System for Children, Second Edition (BASC-2), a validated measure of childhood behavior and emotion. The association between allergic diseases at age 4, including allergic rhinitis, allergic persistent wheezing, atopic dermatitis, and allergic sensitization, and BASC-2 internalizing, anxiety, and depression T scores at age 7 was examined by logistic and linear regression, adjusting for covariates. RESULTS: The cohort included 546 children with complete information on allergic disease and BASC-2 outcomes. Allergic rhinitis at age 4 was significantly associated with elevated internalizing (adjusted odds ratio [aOR]: 3.2; 95% confidence interval [CI]: 1.8–5.8), anxiety (aOR: 2.0; 95% CI: 1.2–3.6), and depressive scores (aOR: 3.2; 95% CI: 1.7–6.5) at age 7. Allergic persistent wheezing was significantly associated with elevated internalizing scores (aOR: 2.7; 95% CI: 1.2–6.3). The presence of >1 allergic disease (aOR: 3.6; 95% CI: 1.7–7.6) and allergic rhinitis with comorbid allergic disease(s) (aOR: 4.3; 95% CI: 2.0–9.2) at age 4 had dose-dependent associations with internalizing scores. CONCLUSIONS: Children with allergic rhinitis and allergic persistent wheezing at age 4 are at increased risk of internalizing behaviors at age 7. Furthermore, multiple allergic diseases had a dose-dependent association with elevated internalizing scores. PMID:26715608

The presence of >1 allergic disease (aOR: 3.6; 95% CI: 1.7-7.6) and allergic rhinitis with comorbid allergic disease(s) (aOR: 4.3; 95% CI: 2.0-9.2) at age 4 had dose-dependent associations with internalizing scores. Children with allergic rhinitis and allergic persistent wheezing at age 4 are at increased risk of internalizing behaviors at age 7. Furthermore, multiple allergic diseases had a dose-dependent association with elevated internalizing scores. Copyright © 2016 by the American Academy of Pediatrics.

Facilitation of Allergic Sensitization and Allergic Airway Inflammation by Pollen-Induced Innate Neutrophil Recruitment

Neutrophil recruitment is a hallmark of rapid innate immune responses. Exposure of airways of naive mice to pollens rapidly induces neutrophil recruitment. The innate mechanisms that regulate pollen-induced neutrophil recruitment and the contribution of this neutrophilic response to subsequent induction of allergic sensitization and inflammation need to be elucidated. Here we show that ragweed pollen extract (RWPE) challenge in naive mice induces C-X-C motif ligand (CXCL) chemokine synthesis, which stimulates chemokine (C-X-C motif) receptor 2 (CXCR2)-dependent recruitment of neutrophils into the airways. Deletion of Toll-like receptor 4 (TLR4) abolishes CXCL chemokine secretion and neutrophil recruitment induced by a single RWPE challenge and inhibits induction of allergic sensitization and airway inflammation after repeated exposures to RWPE. Forced induction of CXCL chemokine secretion and neutrophil recruitment in mice lacking TLR4 also reconstitutes the ability of multiple challenges of RWPE to induce allergic airway inflammation. Blocking RWPE-induced neutrophil recruitment in wild-type mice by administration of a CXCR2 inhibitor inhibits the ability of repeated exposures to RWPE to stimulate allergic sensitization and airway inflammation. Administration of neutrophils derived from naive donor mice into the airways of Tlr4 knockout recipient mice after each repeated RWPE challenge reconstitutes allergic sensitization and inflammation in these mice. Together these observations indicate that pollen-induced recruitment of neutrophils is TLR4 and CXCR2 dependent and that recruitment of neutrophils is a critical rate-limiting event that stimulates induction of allergic sensitization and airway inflammation. Inhibiting pollen-induced recruitment of neutrophils, such as by administration of CXCR2 antagonists, may be a novel strategy to prevent initiation of pollen-induced allergic airway inflammation.

Because of its burden on patient's lives and its impact on asthma, allergic rhinitis must be treated properly with more effective and safer treatments. According to guidelines by Allergic Rhinitis and Its Impact on Asthma (ARIA), the classification, pathogenesis, and treatment of allergic rhinitis are well defined. Currently, second-generation antihistamines and inhaled steroids are considered the cornerstone of first-line therapy. However, new formulations of available drugs (e.g., loratadine and rupatadine oral solution, ebastine fast-dissolving tablets, and the combination of intranasal fluticasone propionate and azelastine hydrochloride), recently discovered molecules (e.g., ciclesonide, bilastine, and phosphodiesterase-4 inhibitors), immunologic targets (e.g., omalizumab), and unconventional treatments (e.g., homeopathic treatments) are currently under investigation and represent a new frontier in modern medicine and in allergic rhinitis management. The aim of this review is to provide an update on allergic rhinitis treatment, paying particular attention to clinical trials published within the past 20 months that assessed the efficacy and safety of new formulations of available drugs or new molecules.

Granulomatous Lobular Mastitis Following Drug-Induced Galactorrhea and Blunt Trauma.

1999-11-01

We report a single case of chronic granulomatous lobular mastitis following metoclopramide-related galactorrhea and a blunt trauma in a young parous woman who underwent two conservative operations before becoming symptom-free. We have found only two other literature cases associated with hyperprolactinemia, and our case could be another of this etiologic group. The absence of well-formed granulomas in the first histology specimen in the present case was misleading; it was reinterpreted as granulomatous mastitis only after the second specimen was examined. Reinterpretation was based on the lobular distribution of a lymphoplasmocytic infiltrate (nonspecific chronic lobulitis) and the presence of epithelioid cell sheets and neutrophils in the absence of well-formed granulomas. The case lends further support to the theory of a local immune response initiated by the secreted material or by one of its components in the formation of granulomas. However, contributory factors such as the trauma in this case (a blow from a shovel handle) or systemic disease in others may play a role in the development of the disease, which in some instances may represent a pattern of tissue reactions to different noxious agents.

Background Cesarean delivery may alter neonatal immune responses and increase the risk of atopy. Studies of the relation between cesarean delivery and allergic diseases in children not selected on the basis of a family history of atopy have yielded inconsistent findings. Objective To examine the relation between birth by cesarean delivery and atopy and allergic diseases in children at risk for atopy. Methods We examined the relation between mode of delivery and the development of atopy and allergic diseases among 432 children with parental history of atopy followed from birth to age 9 years. Asthma was defined as physician-diagnosed asthma and wheeze in the previous year and allergic rhinitis as physician-diagnosed allergic rhinitis and naso-ocular symptoms apart from colds in the previous year. Atopy was considered present at school age if there was >=1 positive skin test or specific IgE to common allergens. Stepwise logistic regression was used to study the relation between cesarean delivery and the outcomes of interest. Results After adjustment for other covariates, children born by cesarean section had twofold higher odds of atopy than those born by vaginal delivery (OR=2.1, 95% CI=1.1–3.9). In multivariate analyses, birth by cesarean section was significantly associated with increased odds of allergic rhinitis (OR=1.8, 95% CI=1.0–3.1) but not with asthma. Conclusions Our findings suggest that cesarean delivery is associated with allergic rhinitis and atopy among children with parental history of asthma or allergies. This could be explained by lack of contact with the maternal vaginal/fecal flora or reduced/absent labor during cesarean delivery. Clinical Implications Potential development of allergic diseases should be considered as a potential risk of cesarean delivery among children with parental history of atopy. Capsule Summary Cesarean delivery may lead to an increased risk of allergic rhinitis and atopy in children with parental history of atopy. PMID

Allergic diseases and air pollution.

PubMed

Lee, Suh-Young; Chang, Yoon-Seok; Cho, Sang-Heon

2013-07-01

The prevalence of allergic diseases has been increasing rapidly, especially in developing countries. Various adverse health outcomes such as allergic disease can be attributed to rapidly increasing air pollution levels. Rapid urbanization and increased energy consumption worldwide have exposed the human body to not only increased quantities of ambient air pollution, but also a greater variety of pollutants. Many studies clearly demonstrate that air pollutants potently trigger asthma exacerbation. Evidence that transportation-related pollutants contribute to the development of allergies is also emerging. Moreover, exposure to particulate matter, ozone, and nitrogen dioxide contributes to the increased susceptibility to respiratory infections. This article focuses on the current understanding of the detrimental effects of air pollutants on allergic disease including exacerbation to the development of asthma, allergic rhinitis, and eczema as well as epigenetic regulation.

To evaluate SPECT/CT with radiolabeled somatostatin analogues (RSAs) in systemic granulomatous infections in comparison with gallium-67 ( 67 Ga) citrate scintigraphy. We studied 28 patients with active systemic granulomatous infections, including tuberculosis, paracoccidioidomycosis, pneumocystosis, cryptococcosis, aspergillosis, leishmaniasis, infectious vasculitis, and an unspecified opportunistic infection. Of the 28 patients, 23 had started specific treatment before the study outset. All patients underwent whole-body SPECT/CT imaging: 7 after injection of 99m Tc-EDDA-HYNIC-TOC, and 21 after injection of 111 In-DTPA-octreotide. All patients also underwent 67 Ga citrate imaging, except for one patient who died before the 67 Ga was available. In 20 of the 27 patients who underwent imaging with both tracers, 27 sites of active disease were detected by 67 Ga citrate imaging and by SPECT/CT with an RSA. Both tracers had negative results in the other 7 patients. RSA uptake was visually lower than 67 Ga uptake in 11 of the 20 patients with positive images and similar to 67 Ga uptake in the other 9 patients. The only patient who did not undergo 67 Ga scintigraphy underwent 99m Tc-EDDA-HYNIC-TOC SPECT/CT-guided biopsy of a lung cavity with focal RSA uptake, which turned to be positive for aspergillosis. SPECT/CT with 99m Tc-EDDA-HYNIC-TOC or 111 In-DTPA-octreotide seems to be a good alternative to 67 Ga citrate imaging for the evaluation of patients with systemic granulomatous disease.

To report a case of bilateral granulomatous post-streptococcal syndrome uveitis in association with reactive arthritis as manifestation of post-streptococcal syndrome. To our knowledge, this could represent the first reported case in the literature. A 9-year-old girl, with no past ocular history, presented with a 5-day history of bilateral blurred vision, red eyes, photophobia and walking difficulties because of a right ankle pain. Ophthalmic examination disclosed a visual acuity limited to hand motion, mutton-fat keratic precipitates, anterior chamber cells and posterior synechiae in both eyes. Ocular pressure was normal. Physical examination showed a fever (38 °C), inflammatory ankle arthritis and scarlet fever (streptococcal lesion). Anti-streptococcal lysine O titer was 419 μ/ml. The patient was treated with topical steroids, cycloplegics, high-dose oral steroids and preventive course of penicillin with total improvement and no recurrence. Post-streptococcal syndrome should be considered in the etiology of acute bilateral granulomatous uveitis in children, and anti-streptococcal lysine O titer should be considered in serodiagnostic testing.

The simultaneous occurrence of pyoderma gangrenosum (PG) and chronic granulomatous disease (CGD) is uncommon and few cases have been reported worldwide. PG is a rare, chronic, ulcerative, neutrophilic skin disease of unknown etiology that requires immunosuppressive treatment. CGD belongs to Primary Immune Deficiencies in which the main defect lies in an inability of the phagocytic cells to generate superoxide making patients susceptible to serious, potentially life-threatening bacterial and fungal infections. In this manuscript, we present a case of ulcerative pyoderma gangrenosum in a 28-year-old man with recent diagnosis of chronic granulomatous disease during hospitalization for resistant pulmonary tuberculosis complicated with Aspergillus infection. Second-line therapy with dapsone and intravenous immunoglobulin was initially administered but eventually corticosteroids were added to treatment because of disease progression and further ulceration. Patient's ulcers were gradually healed with no side effects. Corticosteroids could be used under close monitoring for the treatment of PG in a patient with CGD, despite the increased risk for infections.

2014-01-01

Background It has been well known that pediatric allergic rhinitis was associated with poor performance at school due to attention deficit. However, there were no cohort studies for the effect of treatment of allergic rhinitis on attention performance in pediatric population. Thus, the aim of this study was to investigate whether attention performance was improved after treatment in children with allergic rhinitis. Methods In this ARCO-Kids (Allergic Rhinitis Cohort Study for Kids), consecutive pediatric patients with rhinitis symptoms underwent a skin prick test and computerized comprehensive attention test. According to the skin prick test results, the children were diagnosed as allergic rhinitis or non- allergic rhinitis. All of the patients were regularly followed up and treated with oral medication or intranasal corticosteroid sprays. The comprehensive attention tests consisted of sustained and divided attention tasks. Each of the tasks was assessed by the attention score which was calculated by the number of omission and commission errors. The comprehension attention test was repeated after 1 year. Results A total of 797 children with allergic rhinitis and 239 children with non-allergic rhinitis were included. Initially, the attention scores of omission and commission errors on divided attention task were significantly lower in children with allergic rhinitis than in children with non-allergic rhinitis. After 1 year of treatment, children with allergic rhinitis showed improvement in attention: commission error of sustained (95.6±17.0 vs 97.0±16.6) and divided attention task (99.1±15.8 vs 91.8±23.5). Meanwhile, there was no significant difference of attention scores in children with non-allergic rhinitis. Conclusions Our study showed that management of allergic rhinitis might be associated with improvement of attention. PMID:25330316

Regulatory T cells in Allergic Diseases

PubMed Central

Rivas, Magali Noval; Chatila, Talal A.

2016-01-01

The pathogenesis of allergic diseases entails an ineffective tolerogenic immune response towards allergens. Regulatory T cells (TReg) cells play a key role in sustaining immune tolerance to allergens, yet mechanisms by which TReg cells fail to maintain tolerance in allergic diseases are not well understood. We review current concepts and established mechanisms regarding how TReg cells regulate different components of allergen-triggered immune responses to promote and maintain tolerance. We will also discuss more recent advances that emphasize the “dual” functionality of TReg cells in allergic diseases: how TReg cells are essential in promoting tolerance to allergens but also how a pro-allergic inflammatory environment can skew TReg cells towards a pathogenic phenotype that aggravates and perpetuates disease. These advances highlight opportunities for novel therapeutic strategies that aim to re-establish tolerance in chronic allergic diseases by promoting TReg cell and stability function. PMID:27596705

Alkylphenols--potential modulators of the allergic response.

The prevalence of allergic diseases has increased in recent decades. Allergic diseases, particularly asthma, are complex diseases with strong gene-environment interactions. Epidemiological studies have identified a variety of risk factors for the development of allergic diseases. Among them, endocrine-disrupting chemicals (EDCs) play an important role in triggering or exacerbating these diseases. 4-Nonylphenol (NP) and 4-octylphenol (OP)--two major alkylphenols--have been recognized as common toxic and xenobiotic endocrine disrupters. Due to their low solubility, high hydrophobicity, and low estrogenic activity, they tend to accumulate in the human body and may be associated with the adverse effects of allergic diseases. Recently, new evidence has supported the importance of alkylphenols in the in vitro allergic response. This review focuses on the effects of alkylphenols on several key cell types in the context of allergic inflammation. Copyright © 2012. Published by Elsevier B.V.

Immunization of egg-allergic children against measles, mumps, and rubella (MMR) is often deferred or even denied, although the safety of this vaccination has been clearly shown. Moreover, the majority of severe allergic reactions have occurred in egg-tolerant vaccinees. Other allergenic vaccine components have been sought, and gelatin has been suggested as one cause of allergic adverse events. The aim of this study was to further characterize the actual allergenic vaccine components. Serum samples from 36 recipients of MMR vaccine with anaphylaxis, urticaria with or without angioedema, asthmatic symptoms, or Henoch-Schönlein purpura were analyzed by CAP System radioallergosorbent test (RAST) and immunospot methods to detect the allergenic vaccine component. To evaluate the correspondence between the findings in the CAP System RAST or the immunospot and clinical symptoms, histories of allergies and present hypersensitivity symptoms were assessed. Of the 36 participants, 10 were demonstrated to be allergic to gelatin. Seven of them had persistent allergic symptoms, possibly attributable to foods containing gelatin or cross-reactive allergens. The results of the immunospot suggested concomitant allergy to gelatin and egg, chicken, and feathers, as well as cow's milk, or they reflected allergen cross-reactivity. Although severe allergic adverse events attributable to MMR vaccination are extremely rare, all serious allergic reactions should be further assessed to detect the likely causative vaccine component, including gelatin. The current recommendation for immunization of egg-allergic persons according to standard MMR vaccination schedules is reinforced. measles, mumps, and rubella vaccine, immunization, adverse effects, allergic reactions, gelatin allergy, CAP System, radioallergosorbent test, immunospot, immunoglobulin E.

The butyrophilin-like 2 (BTNL2) G16071A gene polymorphism has been implicated in the susceptibility to granulomatous diseases, but the results were inconclusive. The objective of the current study was to precisely explore the relationship between BTNL2 G16071A gene polymorphism and granulomatous disease susceptibility by the meta-analysis including false-positive report probability (FPRP) test. A systematic literature search in the PubMed, Embase, and Wanfang databases, China National Knowledge Internet, and commercial Internet search engines was conducted to identify studies published up to April 1, 2016. The odds ratio (OR) with 95% confidence interval (CI) was used to assess the effect size. Statistical analysis was conducted using the STATA 12.0 software and FPRP test sheet. In total, all 4324 cases and 4386 controls from 14 eligible studies were included in the current meta-analysis. By the overall meta-analysis, we found a significant association between BTNL2 G16071A gene polymorphism and granulomatous disease susceptibility (A vs G: OR = 1.25, 95% CI = 1.07-1.45, P = 0.005). The meta-regression analyses showed that a large proportion of the between-study heterogeneity was significantly attributed to the ethnicity (A vs G, P = 0.013) and the types of granulomatous diseases (A vs G, P = 0.002). By the subgroup meta-analysis, the BTNL2 G16071A gene polymorphism was associated with granulomatous disease susceptibility in Caucasians (A vs G: OR = 1.37, 95% CI = 1.18-1.58, P < 0.001). Moreover, a significant relationship between the BTNL2 G16071A gene polymorphism and sarcoidosis susceptibility (A vs G: OR = 1.52, 95% CI = 1.39-1.66, P < 0.001) was found. However, to avoid the "false-positive report," we further investigated the significant associations observed in the present meta-analysis by the FPRP test. Interestingly, the results of FPRP test indicated that the BTNL2 G16071A gene polymorphism was truly associated

The purpose of this study is to report a case of otopolyposis and middle ear allergic mucin in a patient with allergic fungal rhinosinusitis (AFRS) and no history of middle ear disease and introduce these as possible otologic manifestations of the AFRS. A case of a 31-year-old female with the aforementioned findings is reported. A review of the pertinent literature was performed. We report a case of a 31-year-old female with a history of AFRS but no history of middle ear disease or hearing loss who presented to our institution complaining of aural fullness. Physical exam was significant for middle ear masses of unknown etiology. Surgical exploration revealed the presence of allergic mucin and middle ear polyposis histologically identical to tissue sampled during prior sinonasal surgeries at the same institution. Aspiration of the middle ear space did not resolve the otologic symptoms. Otopolyposis and middle ear allergic mucin are extremely rare but possible otologic manifestations of AFRS. We encourage otolaryngologists to consider this in the clinical differential diagnosis of patients with a history of AFRS with new onset otologic symptoms. © The Author(s) 2016.

Mycobacterium W (Mw) vaccine has been found to be effective in the treatment of leprosy and warts. Despite increasing use of Mw immunotherapy, data on its safety is limited. We report a series of eight patients who developed persisting injection site granulomatous reaction following Mw immunotherapy and were successfully treated with minocycline. Eight patients with persistent nodular swelling at the site of Mw injections were identified. Seven of them had received Mw immunotherapy for cutaneous warts and one for verrucous epidermal nevus. The lesions were firm, erythematous, succulent, non-tender nodules confined to the sites of Mw vaccine injections. In 6 of these patients nodules also involved the previously injected areas. Skin biopsy from all patients showed eosinophil rich inflammation admixed with histiocytes and lymphocytes. In addition granulomas were seen in all with septal and nodular panniculitis in four patients. Broken and granular acid-fast bacilli were identified in two cases. All patients were treated with oral minocycline 100 mg/day for a mean of 9 weeks and showed good clinical response. Granulomatous reaction is a rare but significant adverse effect of Mw immunotherapy at cosmetically and functionally imperative sites. Oral minocycline appears to be effective therapy in this situation. © 2016 Wiley Periodicals, Inc.

Objective To evaluate SPECT/CT with radiolabeled somatostatin analogues (RSAs) in systemic granulomatous infections in comparison with gallium-67 (67Ga) citrate scintigraphy. Materials and Methods We studied 28 patients with active systemic granulomatous infections, including tuberculosis, paracoccidioidomycosis, pneumocystosis, cryptococcosis, aspergillosis, leishmaniasis, infectious vasculitis, and an unspecified opportunistic infection. Of the 28 patients, 23 had started specific treatment before the study outset. All patients underwent whole-body SPECT/CT imaging: 7 after injection of 99mTc-EDDA-HYNIC-TOC, and 21 after injection of 111In-DTPA-octreotide. All patients also underwent 67Ga citrate imaging, except for one patient who died before the 67Ga was available. Results In 20 of the 27 patients who underwent imaging with both tracers, 27 sites of active disease were detected by 67Ga citrate imaging and by SPECT/CT with an RSA. Both tracers had negative results in the other 7 patients. RSA uptake was visually lower than 67Ga uptake in 11 of the 20 patients with positive images and similar to 67Ga uptake in the other 9 patients. The only patient who did not undergo 67Ga scintigraphy underwent 99mTc-EDDA-HYNIC-TOC SPECT/CT-guided biopsy of a lung cavity with focal RSA uptake, which turned to be positive for aspergillosis. Conclusion SPECT/CT with 99mTc-EDDA-HYNIC-TOC or 111In-DTPA-octreotide seems to be a good alternative to 67Ga citrate imaging for the evaluation of patients with systemic granulomatous disease.

Complementary and alternative medicine for allergic rhinitis.

Man, Li-Xing

2009-06-01

Otolaryngologists and other physicians who diagnose and treat allergic rhinitis encounter patients who use complementary medicine and alternative remedies. This article reviews the recent literature regarding complementary and alternative therapies for the treatment of allergic rhinitis. There are a myriad of modalities for treating allergic rhinitis. Few are studied with rigorous randomized, double-blind, placebo-controlled trials for clinical efficacy. Often, the biological mechanisms and adverse effects are even less well understood. A few therapies, including spirulina, butterbur, and phototherapy hold some promise. Thus far, complementary and alternative therapies have not been integrated into the general treatment armamentarium of allergic rhinitis. Several studies report beneficial effects of certain alternative treatments for allergic rhinitis. Additional insight into the mechanisms of action, short-term and long-term effects, and adverse events is needed.

Climate change, aeroallergens, and pediatric allergic disease.

PubMed

Sheffield, Perry E; Weinberger, Kate R; Kinney, Patrick L

2011-01-01

The degree to which aeroallergens are contributing to the global increase in pediatric allergic disease is incompletely understood. We review the evidence that links climate change to changes in aeroallergens such as pollen and outdoor mold concentrations and, subsequently, aeroallergen association with pediatric allergic disease. We specifically explore the evidence on both the exacerbation and the development of allergic disease in children related to outdoor pollen and mold concentrations. Pediatric allergic diseases include atopic dermatitis or eczema, allergic rhinitis or hay fever, and some types of asthma in children, typically defined as < 18 years of age. We discuss how the timing of aeroallergen exposure both in utero and in childhood could be associated with allergies. We conclude that the magnitude and type of health impacts due to climate change will depend on improved understanding of the relationship between climatic variables, multiple allergen factors, and allergic disease. Improved public-health strategies such as adequate humidity control, optimum air filtration and ventilation, and improved anticipatory public-health messaging will be critical to adaptation. © 2011 Mount Sinai School of Medicine.

Reducing Environmental Allergic Triggers: Policy Issues.

PubMed

Abramson, Stuart L

The implementation of policies to reduce environmental allergic triggers can be an important adjunct to optimal patient care for allergic rhinitis and allergic asthma. Policies at the local level in schools and other public as well as private buildings can make an impact on disease morbidity. Occupational exposures for allergens have not yet been met with the same rigorous policy standards applied for exposures to toxicants by Occupational Safety and Health Administration. Further benefit may be obtained through policies by local, county, state, and national governments, and possibly through international cooperative agreements. The reduction of allergenic exposures can and should be affected by policies with strong scientific, evidence-based derivation. However, a judicious application of the precautionary principle may be needed in circumstances where the health effect of inaction could lead to more serious threats to vulnerable populations with allergic disease.

The pathophysiology of allergic disease such as asthma and allergic rhinitis tell the similar story: when the endogenous and exogenous inflammatory mechanisms occur disorder, the body may begin with inflammatory cell activation, namely through the release of cytokine and inflammatory mediator role in the corresponding target cells, activate the sensory nerve fiber, acting on the cell organ specificity effect, clinical symptoms. This article is divided into the following five parts focused on the research progress of allergic inflammatory diseases: (1) inflammatory cells; (2) staphylococcus aureus superantigen; (3) small molecules (cytokines, inflammatory mediators, lipid classes medium); (4) nerve fibers and effect cells; (5) genetic and epigenetic factors.

The histological diagnosis of Mycobacterium tuberculosis (MTB) has long been a diagnostic challenge in the anatomical pathology field despite availability of different laboratory methods. Immunohistochemistry (IHC) could not only confirm granulomatous tissue involvement but also demonstrate MTB antigen immunolocalization. This study tries to clarify the details of IHC staining for MTB with pAbBCG. A total of 50 patients undergoing simultaneous biopsy and tissue culture with positive tissue culture for MTB during 2005-2009 were selected from the MRC Department at Masih Daneshvari Hospital, Tehran, Iran. Using the archives of the Pathology Department of this hospital, which is a referral center for pathological lung lesions, hematoxylin and eosin slides of the selected patients were evaluated. Twenty-three confirmed TB granulomatous tissue samples with adequate tissue and number of granulomas were chosen and studied by Ziehl-Neelsen and IHC staining with pAbBCG. A total of 23 cases were evaluated, of which 17 (73.9%) were males. The types of tissue obtained from study cases were as follows: pleura (9 cases, 39.1%), lymph node (cervical, axillary, and thoracic [9 cases, 39.1%]), and lung tissues (5 cases, 21.7%). IHC staining was positive in all samples, whereas Ziehl-Neelsen staining was positive in nine cases of 23 (39.1%). IHC showed positive coarse granular cytoplasmic and round, fragmented bacillary staining. In this study, epithelioid cells clearly showed more positive staining at the periphery rather than at the center of granuloma. There is also positive staining in endothelial cells, fibroblasts, plasma cells, macrophages, and lymphocytes outside the granuloma. Detection of TB in tissue slides is still based on the histological pattern of the granuloma, which has several differential diagnoses with different treatments. Presence of mycobacterial antigens and tissue morphology can be evaluated using the IHC technique. Considering the criteria of positive IHC

Eosinophilic granulomatous gastrointestinal and hepatic abscesses attributable to basidiobolomycosis and fasciolias: a simultaneous emergence in Iraqi Kurdistan

PubMed Central

2013-01-01

Background Deep eosinophilic granulomatous abscesses, as distinguished from eosinophilic subcutaneous abscesses, are rare. Most reports are from the Far-East and India where the most commonly attributed cause is Toxocara. Sulaimaniyah in Northeastern Iraq has experienced an outbreak of eosinophilic granulomatous liver and gastrointestinal (GI) abscesses beginning in 2009. The purpose of this study was to determine the etiology and guide treatment. Methods The study was an ongoing investigation of patients having a histopathologic diagnosis of eosinophilic granulomatous abdominal abscesses in Sulaimaniyah hospitals from May 2009 to August 2012. Tissues were examined for organisms, and Enzyme Linked Immunoabsorbent Assays (ELISA) were performed for serum antibodies to Fasciola hepatica, Toxocara, and Echinococcus granulosus. Results Fourteen patients had granulomatous inflammation surrounding a central necrotizing eosinophilic exudate identified in surgical pathology specimens from abdominal surgeries. Two children and four adults had abscesses that formed GI masses. These patients included a 39 year old male with oropharyngeal and transverse colon disease, and a 48 year old male with liver and GI abscesses. All sites demonstrated a Zygomycete fungus surrounded by eosinophilic Splendori-Hoeppli material consistent with basidiobolomycosis. Five of the six patients with fungal disease were treated by surgery and 4 to 7 months of itraconozol. One child died of intestinal perforation while receiving IV amphotericin B; two adults required additional surgery for recurrent GI obstruction. Eight patients had isolated liver abscesses with no organisms identified by histopathology: ELISA results for F. hepatica were positive for five, borderline for one, and negative for two patients. These eight patients were treated for fascioliasis by surgical resection of localized abscesses and albendazol. One patient serologically positive for F. Hepatica was found to have a common duct

Allergic eye disease, as in most forms of atopy, ranges in severity among individuals from immediate hypersensitivity to a severe and debilitating chronic disease. Dendritic cells play a key role in stimulating pathogenic T cells in allergen re-exposure, or secondary responses. However, molecular cues by dendritic cells underpinning allergic T cell response levels and the impact that this control has on consequent severity of allergic disease are poorly understood. Here, we show that a deficiency in thrombospondin-1, a matricellular protein known to affect immune function, has subsequent effects on downstream T cell responses during allergy, as revealed in an established mouse model of allergic eye disease. More specifically, we demonstrate that a thrombospondin-1 deficiency specific to dendritic cells leads to heightened secondary T cell responses and consequent clinical disease. Interestingly, whereas thrombospondin-1-deficient dendritic cells augmented activity of allergen-primed T cells, this increase was not recapitulated with naïve T cells in vitro. The role of dendritic cell-derived thrombospondin-1 in regulating secondary allergic T cell responses was confirmed in vivo, as local transfer of thrombospondin-1-sufficient dendritic cells to the ocular mucosa of thrombospondin-1 null hosts prevented the development of augmented secondary T cell responses and heightened allergic eye disease clinical responses. Finally, we demonstrate that topical instillation of thrombospondin-1-derived peptide reduces T cell activity and clinical progression of allergic eye disease. Taken together, this study reveals an important modulatory role of dendritic cell-derived thrombospondin-1 on secondary allergic T cell responses and suggests the possible dysregulation of dendritic cell-derived thrombospondin-1 expression as a factor in allergic eye disease severity.

γ-Tocopherol increases responses to allergen challenge in allergic adult mice, but it is not known whether γ-tocopherol regulates the development of allergic disease. Development of allergic disease often occurs early in life. In clinical studies and animal models, offspring of allergic mothers have increased responsiveness to allergen challenge. Therefore, we determined whether γ-tocopherol augments development of allergic responses in offspring of allergic female mice. Allergic female mice were supplemented with γ-tocopherol starting at mating. The pups from allergic mothers developed allergic lung responses, whereas pups from saline-treated mothers did not respond to allergen challenge. The γ-tocopherol supplementation of allergic female mice increased the numbers of eosinophils twofold in the pup bronchoalveolar lavage and lungs after allergen challenge. There was also about a twofold increase in pup lung CD11b+ subsets of CD11c+ dendritic cells and in numbers of these dendritic cells expressing the transcription factor IRF4. There was no change in several CD11b− dendritic cell subsets. Furthermore, maternal supplementation with γ-tocopherol increased the number of fetal liver CD11b+CD11c+ dendritic cells twofold in utero. In the pups, γ-tocopherol increased lung expression of the inflammatory mediators CCL11, amphiregulin, activin A, and IL-5. In conclusion, maternal supplementation with γ-tocopherol increased fetal development of subsets of dendritic cells that are critical for allergic responses and increased development of allergic responses in pups from allergic mothers. These results have implications for supplementation of allergic mothers with γ-tocopherol in prenatal vitamins. PMID:26801566

Contact-Allergic Reactions to Cosmetics

Contact-allergic reactions to cosmetics may be delayed-type reactions such as allergic and photo-allergic contact dermatitis, and more exceptionally also immediate-type reactions, that is, contact urticaria. Fragrances and preservative agents are the most important contact allergens, but reactions also occur to category-specific products such as hair dyes and other hair-care products, nail cosmetics, sunscreens, as well as to antioxidants, vehicles, emulsifiers, and, in fact, any possible cosmetic ingredient. Patch and prick testing to detect the respective culprits remains the golden standard for diagnosis, although additional tests might be useful as well. Once the specific allergens are identified, the patients should be informed of which products can be safely used in the future. PMID:21461388

Allergic conjunctivitis in Asia.

PubMed

Thong, Bernard Yu-Hor

2017-04-01

Allergic conjunctivitis (AC), which may be acute or chronic, is associated with rhinitis in 30%-70% of affected individuals, hence the term allergic rhinoconjunctivitis (AR/C). Seasonal and perennial AC is generally milder than the more chronic and persistent atopic and vernal keratoconjunctivitis. Natural allergens like house dust mites (HDM), temperate and subtropical grass and tree pollen are important triggers that drive allergic inflammation in AC in the Asia-Pacific region. Climate change, environmental tobacco smoke, pollutants derived from fuel combustion, Asian dust storms originating from central/north Asia and phthalates may also exacerbate AR/C. The Allergies in Asia Pacific study and International Study of Asthma and Allergies in Childhood provide epidemiological data on regional differences in AR/C within the region. AC significantly impacts the quality of life of both children and adults, and these can be measured by validated quality of life questionnaires on AR/C. Management guidelines for AC involve a stepped approach depending on the severity of disease, similar to that for allergic rhinitis and asthma. Topical calcineurin inhibitors are effective in certain types of persistent AC, and sublingual immunotherapy is emerging as an effective treatment option in AR/C to grass pollen and HDM. Translational research predominantly from Japan and Korea involving animal models are important for the potential development of targeted pharmacotherapies for AC.

Granulomatous lobular mastitis is a rare, benign, inflammatory breast condition of unknown aetiology that can clinically mimic breast cancer. Awareness of this condition is important, as the appropriate specimens must be taken to confirm the diagnosis and to rule out an infectious aetiology. While surgical excision has been the traditional therapeutic modality, the most appropriate therapy seems to involve the use of corticosteroids, even in the case of recurrence.

To investigate the likelihood of allergic rhinitis and potential co-morbidities, and to assess whether allergic rhinitis is associated with arterial blood pressure and hypertension. In this population-based study, 369 adults with allergic rhinitis and asthma were assessed via a questionnaire and immunoglobulin E levels. There were four groups: control (n = 90), allergic rhinitis (n = 99), asthma (n = 87) and hypertension (n = 93). Arterial blood pressure was measured in all groups. There were no significant differences in systolic or diastolic blood pressure between males and females in any group. Pairwise comparisons revealed no significant differences between: the control and allergic rhinitis groups, the control and asthma groups, or the allergic rhinitis and asthma groups. The systolic and diastolic blood pressure values of males and females were significantly higher in the hypertension group than the allergic rhinitis group. There were no significant differences in systolic blood pressure or diastolic blood pressure for seasonal and perennial allergic rhinitis patients. Rhinitis was not associated with increased blood pressure. Allergic rhinitis can coincide with asthma and hypertension. The findings do not support the need for blood pressure follow up in allergic rhinitis patients.

Environmental contributions to allergic disease.

Levetin, E; Van de Water, P

The environment is a major contributor to allergic disease, and great effort is being expended to identify the chemical pollutants and allergens that make a significant impact. Exposure to high levels of ozone, sulfur dioxide, nitrogen dioxide, and diesel exhaust particles is known to reduce lung function. Studies continue to delineate the role of these particles as adjuvants and carriers of allergens into the respiratory system. Current studies also show the exacerbation of allergic disease through fungal spore inhalation and continue to document the role of pollen in allergic rhinitis. Pollen also was recently associated with asthma epidemics, especially after thunderstorms. Forecasting models currently are being developed that predict the trajectories of pollen dispersal and may allow increased avoidance of dangerous outdoor conditions.

Immunomodulation: the future cure for allergic diseases.

PubMed

Tsitoura, Daphne C; Tassios, Yannis

2006-11-01

Allergies are the result of aberrant immune reactivity against common innocuous environmental proteins (allergens). A pivotal component of allergic pathogenesis is the generation of allergen-specific Th cells with an effector phenotype. These Th cells activate a complex immune cascade that triggers the release of potent mediators and enhances the mobilization of several inflammatory cells types, which in turn elicit the acute allergic reactions and promote the development of chronic inflammation. The current therapies for allergic diseases focus primarily on pharmacological control of symptoms and suppression of inflammation. This approach is beneficial, but not curative, since the underlying immune pathology is not inhibited. In an attempt to develop more effective therapeutic strategies, the scientific interest has been directed toward methods down-modulating the immune mechanisms that initiate and maintain the allergic cascade. Today, the only widely used disease-modifying form of allergy treatment is the specific immunotherapy with allergen extracts. More recently the use of anti-IgE has been approved for patients with allergic asthma. Other immunomodulatory methods being currently explored are the administration of microbial adjuvants that inhibit Th2 reactivity and the design of molecules that interrupt the activity of key allergic cytokines, chemokines, or other Th2 effector mediators.

House dust mites, pets, microorganisms such as fungi and bacteria are the main causes of indoor allergens. The diseases correlated to the presence of these allergens are of increasing importance in public health as well as in occupational medicine. Indoor allergens are widespread in residential buildings as well as in public and in office buildings. Surveys conducted in Italian office buildings demonstrated detectable allergen concentrations in most of these buildings. In some cases, the concentrations were higher than the proposed risk threshold for allergenic sensitisation or for the elicitation of symptoms in allergic individuals. The health effects of exposure to indoor allergens mainly include allergic asthma and rhinoconjunctivitis caused by IgE reactions in predisposed subjects. Moreover, exposure to indoor biological agents can cause extrinsic allergic alveolitis or other effects such as the so-called "humidifier fever" due to contaminated humidifiers. Standardized methods for the measurement of indoor allergen levels are available, and may be useful for the diagnosis and treatment of individual allergic patients or for group studies in order to evaluate the relationship between allergen indoor levels and health effects or to assess indoor allergen levels in private or public buildings for preventative purposes.

Routine immunization, one of the most effective public health interventions, has effectively reduced death and morbidity due to a variety of infectious diseases. However, allergic reactions to vaccines occur very rarely and can be life threatening. Given the large numbers of vaccines administered worldwide, there is a need for an international consensus regarding the evaluation and management of allergic reactions to vaccines. Following a review of the literature, and with the active participation of representatives from the World Allergy Organization (WAO), the European Academy of Allergy and Clinical Immunology (EAACI), the American Academy of Allergy, Asthma, and Immunology (AAAAI), and the American College of Allergy, Asthma, and Immunology (ACAAI), the final committee was formed with the purpose of having members who represented a wide-range of countries, had previously worked on vaccine safety, and included both allergist/immunologists as well as vaccinologists. Consensus was reached on a variety of topics, including: definition of immediate allergic reactions, including anaphylaxis, approaches to distinguish association from causality, approaches to patients with a history of an allergic reaction to a previous vaccine, and approaches to patients with a history of an allergic reaction to components of vaccines. This document provides comprehensive and internationally accepted guidelines and access to on-line documents to help practitioners around the world identify allergic reactions following immunization. It also provides a framework for the evaluation and further management of patients who present either following an allergic reaction to a vaccine or with a history of allergy to a component of vaccines.

To study the clinicopathologic features of granulomatous lobular mastitis and mammary duct ectasia. The clinicopathologic data from August 2005 to May 2013 of 32 cases of granulomatous lobular mastitis and mammary duct ectasia were retrospectively reviewed. The age of patients ranged from 26 to 45 years. Two patients had no history of delivery. Fourteen patients had no history of lactation or lactational disorder in the lesional side. Most of the remaining patients had history of breast feeding. Gross examination showed that the lesions were poorly circumscribed and varied from 3 to 12 cm in greatest dimension. Tiny abscess cavities, ranging from 0.1 to 0.5 cm in diameter and containing light yellowish to greyish secretion, were demonstrated. Histologic examination showed granuloma formation and ductal dilatation. Eleven patients had received antibiotic treatment. Twelve cases were complicated by sinus formation related to skin incision and drainage. The duration of follow-up ranged from 5 to 90 months. Three cases showed ipsilateral recurrence and 3 cases had similar pathology in the contralateral breast. Four patients defaulted follow-up. Granulomatous lobular mastitis is associated with mammary duct ectasia. Accurate pathologic diagnosis is prudent for clinical management and control of local recurrence.

Q fever is a worldwide distributed zoonotic disease with a mostly benign course, which regularly reoccurs in Germany. This report is about a patient with sporadic serologically proven Q fever, which also showed typical histopathological findings with nonspecific granulomatous hepatitis, usually seen in acute disease. The bone marrow biopsy revealed so-called doughnut granulomas, which are not pathognomonic but a typical finding in Q fever. This case report impressively underlines that the histomorphological findings can make a decisive contribution to the clarification by extended differential diagnostics, even though it plays a subordinate role in the routine diagnostics of disseminated Q fever.

Pulmonary Aspergillus infection in patients with chronic granulomatous disease tends to involve the chest wall and consequently carries a high mortality rate. We report the findings of computed tomography (CT) and magnetic resonance imaging (MRI) in three such cases. One patient underwent both CT and MRI, one, CT only, and one, MRI only. In all three, both CT and MRI demonstrated pulmonary consolidations with direct extension to the adjacent chest wall. In both patients who were examined by CT, scans revealed permeative osteolytic changes of adjacent rib or spine compatible with osteomyelitis. In both patients who were examined by MRI, adjacent chest wall involvement was depicted on T1-weighted images and showed increased signal intensity on T2-weighted images. In one of these patients, the chest wall lesion was well defined on T2-weighted images, an appearance compatible with abscess. Epidural extension was demonstrated on MRI in the other patient, who later developed paraparesis. We suggest that CT and MRI have a complementary role in evaluating chest wall invasion by pulmonary Aspergillus infection in chronic granulomatous disease.

Objective: To report a rare case of incipient granulomatous hypophysitis presenting by atypical trigemino-autonomic cephalalgia (TAC) and Horner syndrome. Methods: The patient was investigated with repeated brain MRI, CSF examination, thoracic CT, Doppler and duplex ultrasound of the cerebral arteries, and extensive serologic screening for endocrine and autoimmune markers. Written informed consent was obtained from the patient for access to clinical files for research purposes and for publication. Results: We present a middle-aged woman with a history of an autoimmune pancreatitis type 2 who had therapy-refractory TAC with Horner syndrome. Initial cerebral MRI showed only indistinct and unspecific signs of a pathologic process. A biopsy revealed a granulomatous hypophysitis. The symptoms disappeared after transsphenoidal subtotal resection of the pituitary mass and anti-inflammatory therapy. Conclusions: This case elucidates that inflammatory pituitary diseases must be taken into account in case of atypical and refractory TAC, especially in patients with a history of autoimmune diseases. To our knowledge, the association between TAC accompanied by Horner syndrome and hypophysitis has not yet been described before. PMID:28243612

The prevalence of allergic rhinitis is increasing globally due to various causes. It affects the quality life of a large group of people in all around the world. Allergic rhinitis still remains inadequately controlled with present medical means. The need of continuous medical therapy makes individuals anxious about the side effects of the drugs. So there is a need for an alternative strategy. Effects of spirulina, tinospora cordifolia and butterbur were investigated recently on allergic rhinitis in just very few investigations. Spirulina represents a blue-green alga that is produced and commercialized as a dietary supplement for modulating immune functions, as well as ameliorating a variety of diseases. This double blind, placebo controlled study, evaluated the effectiveness and tolerability of spirulina for treating patients with allergic rhinitis. Spirulina consumption significantly improved the symptoms and physical findings compared with placebo (P < 0.001***) including nasal discharge, sneezing, nasal congestion and itching. Spirulina is clinically effective on allergic rhinitis when compared with placebo. Further studies should be performed in order to clarify the mechanism of this effect.

Sensitization in adults has not been extensively studied. To investigate patterns of allergen sensitization in parents of food allergic children and to compare self-report of allergic disease with specific IgE (sIgE) measurements. A total of 1,252 mothers and 1,225 fathers of food allergic children answered standardized questionnaires about demographics, home environment, history of atopic diseases, and food allergy. Skin prick testing and sIgE serum tests were performed to 9 foods and 5 aeroallergens. A total of 66.1% of parents were sensitized to either a food or aeroallergen. Mean sIgE levels were low for all foods tested. A total of 14.5% of mothers and 12.7% of fathers reported current food allergy. Only 28.4% had sensitization to their reported allergen. Fathers had significantly higher rates of sensitization to both foods and aeroallergens (P < .01) than mothers. Logistic regression evaluating predictors of self-reported food allergy revealed statistically significant positive associations in fathers with self-reported asthma, environmental allergy, and eczema. For mothers, significant positive associations were found with environmental allergy and having more than 1 food allergic child. This cohort of parents of food allergic children found higher rates of sensitization to foods and aeroallergens compared with the general population. However, food sIgE levels were low and correlated poorly with self-reported food allergy. Sex differences in sensitization to foods and aeroallergens were seen.

Allergic disease may be increased by climate change. Recent reports have shown that typhoon and heavy rain increase allergic disease locally by concentration of airborne allergens of pollen, ozone, and fungus, which are causes of allergic disease. The objective of this study was to determine whether typhoon and heavy rain increase allergic disease in Korea. This study included allergic disease patients of the area declared as a special disaster zone due to storms and heavy rains from 2003 to 2009. The study used information from the Korea Meteorological Administration, and from the National Health Insurance Service for allergic diseases (asthma, allergic rhinitis, and atopic dermatitis). During a storm period, the numbers of allergy rhinitis and atopic dermatitis outpatients increased [rate ratio (RR) = 1.191; range, 1.150-1.232] on the sixth lag day. However, the number of asthma outpatients decreased (RR = 0.900; range, 0.862-0.937) on the sixth lag day after a disaster period. During a storm period, the numbers of allergic rhinitis outpatients (RR = 1.075; range, 1.018-1.132) and atopy outpatients increased (RR = 1.134; range, 1.113-1.155) on the seventh lag day. However, the number of asthma outpatients decreased to RR value of 0.968 (range, 0.902-1.035) on the fifth lag day. This study suggests that typhoon and heavy rain increase allergic disease apart from asthma. More study is needed to explain the decrease in asthma.

Methods Twenty-seven patients (27 eyes) diagnosed with sarcoid- (13 eyes) and TB (14 eyes)-related uveitis were included in this retrospective, cross-sectional study. Over a six-month period, patients diagnosed with sarcoid and TB granulomatous uveitis were scanned using enhanced depth imaging OCT. Clinical and demographical characteristics were recorded, including the method of diagnosis, disease activity, site of inflammation (anterior or posterior), treatments, and visual acuity (VA). Manual segmentation of the choroidal layers was performed using custom image analysis software. Results The main outcome measure was OCT-derived thickness measurements of the choroid and choroidal sublayers (Haller's large vessel and Sattler's medium vessel layers) at the macula region. The ratio of Haller's large vessel to Sattler's medium vessel layer was significantly different at the total macula circle in eyes diagnosed with TB uveitis (1.47 (=140.71/95.72 μm)) compared with sarcoid uveitis (1.07 (=137.70/128.69 μm)) (P=0.001). A thinner choroid was observed in eyes with a VA ≥0.3 LogMAR (Snellen 6/12; 198.1 μm (interquartile range (IQR)=147.0–253.4 μm) compared with those with VA <0.3 LogMAR (292.4 μm (IQR=240.1–347.6 μm)) at the total macula circle (P=0.004). At the foveal central subfield, the median choroidal thickness was 336.8 μm (IQR=272.3–375.4 μm) in active compared with 239.3 μm (IQR=195.3–330.9 μm) in quiescent disease (P=0.04). Conclusion A disproportionately enlarged Sattler's layer may indicate a diagnosis of sarcoid-related uveitis, and choroidal thickening may be a feature of active granulomatous uveitis. PMID:26021867

Idiopathic granulomatous mastitis (IGM) is a rare benign inflammatory breast disease that presents with variable local manifestations. We describe here the different management protocols based on the clinical presentation of these patients. A retrospective review of 20 histopathologic confirmed cases of IGM seen over a period of 10 years was performed. The median age was 34 years (age range: 21-45 years). All were married, parous with history of breast feeding. Ill-defined mass mimicking carcinoma was the commonest presentation (70%); however, with the presence of signs of inflammation like pain (55%), redness (40%), and peau d'orange (40%), an inflammatory process appeared more likely. Axillary lymph node enlargement was infrequently seen (40%). Radiologic findings (mammography and ultrasound) were nonspecific. Histopathology showed the characteristic lobular distribution of granulomatous inflammation in all cases. Surgically, 7 patients had abscess drainage with open biopsy, and 7 patients had lumpectomy. Six patients with diffuse breast involvement were diagnosed by core needle biopsy only. Microbial cultures showed no growth. Antibiotics were given empirically when signs of inflammation where present. Two patients needed further abscess drainage followed by persistent sinus excision 3-6 weeks later. The median follow-up was 24 months (range: 15-42 months). Seventeen patients (85%) were recurrence-free, and 3 patients (15%) were lost to follow-up. Management of IGM cases needs to be tailored according to the clinical presentation. Precise radiologic and pathologic data interpretation by a multidisciplinary breast team will facilitate diagnosis and minimize unnecessary intervention.

Previous published results have revealed that Rhinolight ® intranasal phototherapy is safe and effective in intermittent allergic rhinitis. The present objective was to assess whether phototherapy is also safe and effective in persistent allergic rhinitis. Thirty-four patients with persistent allergic rhinitis were randomized into two groups; twenty-five subjects completed the study. The Rhinolight ® group was treated with a combination of UV-B, UV-A, and high-intensity visible light, while the placebo group received low-intensity visible white light intranasal phototherapy on a total of 13 occasions in 6 weeks. The assessment was based on the diary of symptoms, nasal inspiratory peak flow, quantitative smell threshold, mucociliary transport function, and ICAM-1 expression of the epithelial cells. All nasal symptom scores and nasal inspiratory peak flow measurements improved significantly in the Rhinolight ® group relative to the placebo group and this finding persisted after 4 weeks of follow-up. The smell and mucociliary functions did not change significantly in either group. The number of ICAM-1 positive cells decreased non-significantly in the Rhinolight ® group. No severe side-effects were reported during the treatment period. These results suggest that Rhinolight ® treatment is safe and effective in persistent allergic rhinitis.

Climate change and allergic disease.

Climate change is potentially the largest global threat to human health ever encountered. The earth is warming, the warming is accelerating, and human actions are largely responsible. If current emissions and land use trends continue unchecked, the next generations will face more injury, disease, and death related to natural disasters and heat waves, higher rates of climate-related infections, and wide-spread malnutrition, as well as more allergic and air pollution-related morbidity and mortality. This review highlights links between global climate change and anticipated increases in prevalence and severity of asthma and related allergic disease mediated through worsening ambient air pollution and altered local and regional pollen production. The pattern of change will vary regionally depending on latitude, altitude, rainfall and storms, land-use patterns, urbanization, transportation, and energy production. The magnitude of climate change and related increases in allergic disease will be affected by how aggressively greenhouse gas mitigation strategies are pursued, but at best an average warming of 1 to 2 degrees C is certain this century. Thus, anticipation of a higher allergic disease burden will affect clinical practice as well as public health planning. A number of practical primary and secondary prevention strategies are suggested at the end of the review to assist in meeting this unprecedented public health challenge.

The prevalence of allergic diseases has increased all over the world during the last two decades. Dietary change is considered to be one of the environmental factors that cause this increase and worsen allergic symptoms. If this is the case, an appropriate intake of foods or beverages with anti-allergic activities is expected to prevent the onset of allergic diseases and ameliorate allergic symptoms. Flavonoids, ubiquitously present in vegetables, fruits or teas possess anti-allergic activities. Flavonoids inhibit histamine release, synthesis of IL-4 and IL-13 and CD40 ligand expression by basophils. Analyses of structure-activity relationships of 45 flavones, flavonols and their related compounds showed that luteolin, ayanin, apigenin and fisetin were the strongest inhibitors of IL-4 production with an IC(50) value of 2-5 microM and determined a fundamental structure for the inhibitory activity. The inhibitory activity of flavonoids on IL-4 and CD40 ligand expression was possibly mediated through their inhibitory action on activation of nuclear factors of activated T cells and AP-1. Administration of flavonoids into atopic dermatitis-prone mice showed a preventative and ameliorative effect. Recent epidemiological studies reported that a low incidence of asthma was significantly observed in a population with a high intake of flavonoids. Thus, this evidence will be helpful for the development of low molecular compounds for allergic diseases and it is expected that a dietary menu including an appropriate intake of flavonoids may provide a form of complementary and alternative medicine and a preventative strategy for allergic diseases. Clinical studies to verify these points are now in progress.

Objectives Allergic disease may be increased by climate change. Recent reports have shown that typhoon and heavy rain increase allergic disease locally by concentration of airborne allergens of pollen, ozone, and fungus, which are causes of allergic disease. The objective of this study was to determine whether typhoon and heavy rain increase allergic disease in Korea. Methods This study included allergic disease patients of the area declared as a special disaster zone due to storms and heavy rains from 2003 to 2009. The study used information from the Korea Meteorological Administration, and from the National Health Insurance Service for allergic diseases (asthma, allergic rhinitis, and atopic dermatitis). Results During a storm period, the numbers of allergy rhinitis and atopic dermatitis outpatients increased [rate ratio (RR) = 1.191; range, 1.150–1.232] on the sixth lag day. However, the number of asthma outpatients decreased (RR = 0.900; range, 0.862–0.937) on the sixth lag day after a disaster period. During a storm period, the numbers of allergic rhinitis outpatients (RR = 1.075; range, 1.018–1.132) and atopy outpatients increased (RR = 1.134; range, 1.113–1.155) on the seventh lag day. However, the number of asthma outpatients decreased to RR value of 0.968 (range, 0.902–1.035) on the fifth lag day. Conclusion This study suggests that typhoon and heavy rain increase allergic disease apart from asthma. More study is needed to explain the decrease in asthma. PMID:24159545

Chronic granulomatous disease (CGD) is a primary immunodeficiency that confers a markedly increased risk of bacterial and fungal infections caused by certain opportunistic pathogens. Current evidence supports the use of prophylactic antibacterial, antifungal, and immunomodulatory therapies designed to prevent serious or life-threatening infections in patients with CGD. In this review, we discuss current strategies for the prevention of infections in children and adults with CGD and the evidence that supports those strategies. In addition, we address current challenges and opportunities for future research in this important area.

Asthma is one of the most common of medical illnesses and is treated in part by drugs that activate the beta-2-adrenoceptor (β2-AR) to dilate obstructed airways. Such drugs include long acting beta agonists (LABAs) that are paradoxically linked to excess asthma-related mortality. Here we show that LABAs such as salmeterol and structurally related β2-AR drugs such as formoterol and carvedilol, but not short-acting agonists (SABAs) such as albuterol, promote exaggerated asthma-like allergic airway disease and enhanced airway constriction in mice. We demonstrate that salmeterol aberrantly promotes activation of the allergic disease-related transcription factor signal transducer and activator of transcription 6 (STAT6) in multiple mouse and human cells. A novel inhibitor of STAT6, PM-242H, inhibited initiation of allergic disease induced by airway fungal challenge, reversed established allergic airway disease in mice, and blocked salmeterol-dependent enhanced allergic airway disease. Thus, structurally related β2-AR ligands aberrantly activate STAT6 and promote allergic airway disease. This untoward pharmacological property likely explains adverse outcomes observed with LABAs, which may be overcome by agents that antagonize STAT6.

The allergic rhinitis is the most common immune disorder with a lifetime prevalence of 24% and one of the most common chronic diseases at all--with tendency to rise. It occurs in childhood and influences the patients' social life, school performance and labour productivity. Furthermore the allergic rhinitis is accompanied by a lot of comorbidities, including conjunctivitis, asthma bronchiale, food allergy, neurodermatitis and sinusitis. For example the risk for asthma is 3.2-fold higher for adults with allergic rhinitis than for healthy people.

Disturbances of the upper and lower airways frequently coexist, and the association between allergic rhinitis and asthma is an example of that. The relationship between allergic rhinitis and asthma probably occurs because both, nasal and bronchial mucosas are elements of a "united airway", and on the other hand, allergic rhinitis and asthma are manifestations of a common allergic disease. Allergic rhinitis and asthma are not only statistically associated, but have pathophysiological and clinical similarities. Allergic rhinitis is itself a risk factor for the development of asthma, but additionally may confound the diagnosis of asthma and may exacerbate coexisting asthma. The management of allergic rhinitis, mainly with the use of intranasal corticosteroids, improve asthma symptoms and lung function in asthmatic patients. Several mechanisms have been proposed to link the nose and bronchi, which include: postnasal drip of inflammatory cells and pro-inflammatory molecules; a possible nasobronchial neural reflex; an increased exposure of the lower airways to dry and cold air as well as aeroallergens because the mouth breathing secondary to nasal obstruction; and an increased susceptibility to rhinovirus infection secondary to an increased ICAM-1 expression in the nasal mucosa of patients with allergic rhinitis. A better understanding of the rhinitis-asthma relationship nature might allow the creation of better strategies for the integral treatment of patients with these diseases.

Asthma and allergic diseases continue to increase in prevalence, creating a financial burden on the health care system and affecting the quality of life for those who have these diseases. Many intrinsic and extrinsic factors are involved in the initiation and maintenance of the allergic response. Cytokines are proteins with growth, differentiation, and activation functions that regulate and direct the nature of immune responses. clinicaltrials.gov and PubMed. Relevant clinical trials and recent basic science studies were chosen for discussion. Many cytokines have been implicated in the development and perpetuation of the allergic response. Biologics have been and are continuing to be developed that target these molecules for use in patients with asthma and atopic dermatitis where standard treatment options fail. The current state of cytokine-targeting therapies is discussed. This review focused on cytokines involved in the allergic response with an emphasis on those for which therapies are being or have been developed.

Emerging roles of basophils in allergic inflammation.

PubMed

Miyake, Kensuke; Karasuyama, Hajime

2017-07-01

Basophils have long been neglected in immunological studies because they were regarded as only minor relatives of mast cells. However, recent advances in analytical tools for basophils have clarified the non-redundant roles of basophils in allergic inflammation. Basophils play crucial roles in both IgE-dependent and -independent allergic inflammation, through their migration to the site of inflammation and secretion of various mediators, including cytokines, chemokines, and proteases. Basophils are known to produce large amounts of IL-4 in response to various stimuli. Basophil-derived IL-4 has recently been shown to play versatile roles in allergic inflammation by acting on various cell types, including macrophages, innate lymphoid cells, fibroblasts, and endothelial cells. Basophil-derived serine proteases are also crucial for the aggravation of allergic inflammation. Moreover, recent reports suggest the roles of basophils in modulating adaptive immune responses, particularly in the induction of Th2 differentiation and enhancement of humoral memory responses. In this review, we will discuss recent advances in understanding the roles of basophils in allergic inflammation. Copyright © 2017 Japanese Society of Allergology.

The past 15 years of allergic disease research have produced extraordinary improvements in our understanding of the pathogenesis of airway allergic diseases such as asthma. Whereas it was previously viewed as largely an immunoglobulin E-mediated process, the gradual recognition that T cells, especially Type 2 T helper (Th2) cells and Th17 cells, play a major role in asthma and related afflictions has inspired clinical trials targeting cytokine-based inflammatory pathways that show great promise. What has yet to be clarified about the pathogenesis of allergic inflammatory disorders, however, are the fundamental initiating factors, both exogenous and endogenous, that drive and sustain B- and T-cell responses that underlie the expression of chronic disease. Here we review how proteinases derived from diverse sources drive allergic responses. A central discovery supporting the proteinase hypothesis of allergic disease pathophysiology is the role played by airway fibrinogen, which in part appears to serve as a sensor of unregulated proteinase activity and which, when cleaved, both participates in a novel allergic signaling pathway through Toll-like receptor 4 and forms fibrin clots that contribute to airway obstruction. Unresolved at present is the ultimate source of airway allergenic proteinases. From among many potential candidates, perhaps the most intriguing is the possibility such enzymes derive from airway fungi. Together, these new findings expand both our knowledge of allergic disease pathophysiology and options for therapeutic intervention. PMID:25525732

To evaluate the multi-parametric MRI (mpMRI) findings in patients with biopsy-proven granulomatous prostatitis and prior Bacillus Calmette-Guérin (BCG) exposure. MRI was performed in six patients with pathologically proven granulomatous prostatitis and a prior history of bladder cancer treated with intravesical BCG therapy. Multi-parametric prostate MRI images were recorded on a GE 750W or Philips Achieva 3.0 Tesla MRI scanner with high-resolution, small-field-of-view imaging consisting of axial T2, axial T1, coronal T2, sagittal T2, axial multiple b-value diffusion (multiple values up to 1200 or 1400), and dynamic contrast-enhanced 3D axial T1 with fat suppression sequence. Two different patterns of MR findings were observed. Five of the six patients had a low mean ADC value <1000 (decreased signal on ADC map images) and isointense signal on high-b-value imaging (b = 1200 or 1400), consistent with nonspecific granulomatous prostatitis. The other pattern seen in one of the six patients was decreased signal on the ADC map images with increased signal on the high-b-value sequence, revealing true restricted diffusion indistinguishable from aggressive prostate cancer. This patient had biopsy-confirmed acute BCG prostatitis. Our study suggests that patients with known BCG exposure and PI-RADS v2 scores ≤3, showing similar mpMRI findings as demonstrated, may not require prostate biopsy.

Certain nematode infections induce eosinophil infiltration and granulomatous responses in the lungs. To examine the role of mast cells in the development of lung lesions, normal +/+ and genetically mast cell-deficient Ws/Ws rats were infected with the nematode Nippostrongylusbrasiliensis. In +/+ rats, numbers of eosinophils in bronchoalveolar lavage fluid (BALF) increased significantly 3–7 days after infection, and granulomatous responses composed of histiocytes/macrophages and multinucleate giant cells were triggered in the lungs 3–14 days after infection. Challenge infection, which was carried out on day 28 after primary infection, induced much higher levels of granulomatous response than after primary infection, suggesting that the response is mediated at least in part by an immunological mechanism. In Ws/Ws rats, both the eosinophil percentage in BALF and the size of the granulomas in the lungs were significantly smaller than in +/+ rats after primary as well as after challenge infection. The amount of rat mast cell protease (RMCP) II in +/+ rat BALF was increased 1 day after primary infection and more significantly after challenge infection, suggesting that lung mucosal mast cells were activated more markedly after the challenge infection. In Ws/Ws rats, RMCP II was undetectable throughout the observation period. The time course of nematode migration in the lungs did not differ in +/+ and Ws/Ws rats. These results suggest that mast cell activation might be relevant to eosinophil infiltration and granulomatous response in the lungs, although the responses do not affect lung migration of the nematode.

Treatment with antibiotics had no effect, and after a week the patient was admitted to hospital for drainage of the abscess and further examination. She had then developed reactive arthritis. Histological examination of a specimen from the mamma revealed lobular granulomatous mastitis. This connection has not been described before in the literature. Further examination showed no signs of infectious disease or sarcoidosis. Surgical drainage had only a minor effect on the breast-mass. The patient was treated with prednisone for six months, and after one year of observation the mass has disappeared, but the arthralgias persists.

To describe post-mortem findings of the first case of neuro-Sweet disease. A 44-year-old Japanese man developed recurrent episodes of cerebral and brainstem encephalitis with cutaneous Sweet lesions from the age of 34 years. His HLA typing was B54 and Cw1, and the symptoms and MRI abnormalities markedly subsided following corticosteroid therapy. Histologically, there were multiple lesions of perivascular cuffing of small venules by macrophages without vasculitis in the thalamus, temporal lobe, basal ganglia, pons, leptomeninges or ventricular ependym. The core neuropathological findings were: perivascular cuffing around particularly small veins; absence of granulomatous or necrotic angitis; mainly macrophage infiltration; and the thalamus being most affected. In the present case, the diagnosis of neuro-Sweet disease was made by skin biopsy 5 years after the onset of the central neuron system symptoms. We should pay more attention to skin lesions in steroid responsive recurrent encephalitis in patients who are HLA-B54 or Cw1 positive.

Food and Natural Materials Target Mechanisms to Effectively Regulate Allergic Responses.

PubMed

Shin, Hee Soon; Shon, Dong-Hwa

2015-01-01

An immune hypersensitivity disorder called allergy is caused by diverse allergens entering the body via skin contact, injection, ingestion, and/or inhalation. These allergic responses may develop into allergic disorders, including inflammations such as atopic dermatitis, asthma, anaphylaxis, food allergies, and allergic rhinitis. Several drugs have been developed to treat these allergic disorders; however, long-term intake of these drugs could have adverse effects. As an alternative to these medicines, food and natural materials that ameliorate allergic disorder symptoms without producing any side effects can be consumed. Food and natural materials can effectively regulate successive allergic responses in an allergic chain-reaction mechanism in the following ways: [1] Inhibition of allergen permeation via paracellular diffusion into epithelial cells, [2] suppression of type 2 T-helper (Th) cell-related cytokine production by regulating Th1/Th2 balance, [3] inhibition of pathogenic effector CD4(+) T cell differentiation by inducing regulatory T cells (Treg), and [4] inhibition of degranulation in mast cells. The immunomodulatory effects of food and natural materials on each target mechanism were scientifically verified and shown to alleviate allergic disorder symptoms. Furthermore, consumption of certain food and natural materials such as fenugreek, skullcap, chitin/chitosan, and cheonggukjang as anti-allergics have merits such as safety (no adverse side effects), multiple suppressive effects (as a mixture would contain various components that are active against allergic responses), and ease of consumption when required. These merits and anti-allergic properties of food and natural materials help control various allergic disorders.

A 5-yr-old, captive, hatched, female false gharial (Tomistoma schlegelii) presented with a 1-mo history of cervical spinal curvature. Antemortem diagnostics, including blood work, electromyography, muscle biopsies, and advanced imaging tests, were either within reference ranges or did not identify any specific etiology. Necropsy revealed extensive, marked, chronic granulomatous encephalomyelitis along with neuronal necrosis, rarefaction, gliosis, and astrocytosis of the white and gray matter of the cerebrum, cerebellum, brainstem, and spinal cord. Pan-chlamydiae polymerase chain reaction protocols for the 16S ribosomal RNA and ompA genes were performed on samples of spinal cord and brain, and both resulted in amplicons. Sequencing of the products revealed that they were positive for a novel Chlamydia species. Infections by members of the phylum Chlamydiae have been reported in a diverse range of vertebrate hosts, including crocodilians. Chlamydia spp. infections are likely underdiagnosed because of a paucity of diagnostic techniques specific for detection. This is the first case report of a novel Chlamydia species associated with severe granulomatous encephalomyelitis in a false gharial.

Basophils and allergic inflammation

Basophils were discovered by Paul Ehrlich in 1879 and represent the least abundant granulocyte population in mammals. The relative rarity of basophils and their phenotypic similarities with mast cells resulted in this cell lineage being historically overlooked, both clinically and experimentally. However, recent studies in humans and murine systems have shown that basophils perform non-redundant effector functions and significantly contribute to the development and progression of TH2 cytokine-mediated inflammation. Although the potential functions of murine and human basophils have provoked some controversy, recent genetic approaches indicate that basophils can migrate into lymphoid tissues and, in some circumstances, cooperate with other immune cells to promote optimal TH2 cytokine responses in vivo. This article provides a brief historical perspective on basophil-related research and discusses recent studies that have identified previously unappreciated molecules and pathways that regulate basophil development, activation and function in the context of allergic inflammation. Further, we highlight the unique effector functions of basophils and discuss their contributions to the development and pathogenesis of allergic inflammation in human disease. Finally, we discuss the therapeutic potential of targeting basophils in preventing or alleviating the development and progression of allergic inflammation. PMID:24075190

Background Chronic granulomatous disease (CGD) is a rare inherited disease of the phagocyte NADPH oxidase system that causes defective production of toxic oxygen metabolites, impaired bacterial and fungal killing, and recurrent life-threatening infections, mostly by catalase-producing organisms. We report for the first time, to our knowledge, chronic infections with Actinomyces species in 10 patients with CGD. Actinomycosis is a chronic granulomatous condition that commonly manifests as cervicofacial, pulmonary, or abdominal disease, caused by slowly progressive infection with oral and gastrointestinal commensal Actinomyces species. Treatment of actinomycosis is usually simple in immunocompetent individuals, requiring long-term, high-dose intravenous penicillin, but is more complicated in those with CGD because of delayed diagnosis and an increased risk of chronic invasive or debilitating disease. Methods Actinomyces was identified by culture, staining, 16S ribosomal DNA polymerase chain reaction, and/ or a complement fixation test in 10 patients with CGD. Results All 10 patients presented with a history of fever and elevated inflammatory signs without evident focus. Diagnosis was delayed and clinical course severe and protracted despite high-dose intravenous antibiotic therapy and/or surgery. These results suggest an unrecognized and unanticipated susceptibility to weakly pathogenic Actinomyces species in patients with CGD because these are catalase-negative organisms previously thought to be nonpathogenic in CGD. Conclusions Actinomycosis should be vigorously sought and promptly treated in patients with CGD presenting with uncommon and prolonged clinical signs of infection. Actinomycosis is a catalase-negative infection important to consider in CGD. PMID:19874205

Most studies of stress in children with chronic diseases have been geared toward parents and caregivers have not considered allergic diseases together. This study aimed to identify the stressors associated with allergic diseases in Japanese school-age children. Stressors associated with allergic diseases of 11 school-age children (seven boys and four girls; age range: 9-12 years) were investigated using semi-structured interviews. In the qualitative thematic analysis of stressors about allergic diseases, two themes: allergic disease-specific stressors and common stressors in chronic diseases, and 12 categories were identified. A thematic map was applied to four domains of stressor: physiological factors, psychological factors, social factors, and environmental factors. The results showed that school-age children with allergic diseases have a variety of stressors. Future studies should aim to develop an allergic disease-specific stress management program with school-age children. In children with allergic diseases, not only is stress management in daily life important, but also stress management for disease-specific matters to control the symptoms and maintain mental health. Stress management should be supported for school-age children with allergic diseases. Copyright © 2018 Elsevier Inc. All rights reserved.

Clinical verification in homeopathy and allergic conditions.

PubMed

Van Wassenhoven, Michel

2013-01-01

The literature on clinical research in allergic conditions treated with homeopathy includes a meta-analysis of randomised controlled trials (RCT) for hay fever with positive conclusions and two positive RCTs in asthma. Cohort surveys using validated Quality of Life questionnaires have shown improvement in asthma in children, general allergic conditions and skin diseases. Economic surveys have shown positive results in eczema, allergy, seasonal allergic rhinitis, asthma, food allergy and chronic allergic rhinitis. This paper reports clinical verification of homeopathic symptoms in all patients and especially in various allergic conditions in my own primary care practice. For preventive treatments in hay fever patients, Arsenicum album was the most effective homeopathic medicine followed by Nux vomica, Pulsatilla pratensis, Gelsemium, Sarsaparilla, Silicea and Natrum muriaticum. For asthma patients, Arsenicum iodatum appeared most effective, followed by Lachesis, Calcarea arsenicosa, Carbo vegetabilis and Silicea. For eczema and urticaria, Mezereum was most effective, followed by Lycopodium, Sepia, Arsenicum iodatum, Calcarea carbonica and Psorinum. The choice of homeopathic medicine depends on the presence of other associated symptoms and 'constitutional' features. Repertories should be updated by including results of such clinical verifications of homeopathic prescribing symptoms. Copyright © 2012 The Faculty of Homeopathy. Published by Elsevier Ltd.

Comparative immunology of allergic responses.

PubMed

Gershwin, Laurel J

2015-01-01

Allergic responses occur in humans, rodents, non-human primates, avian species, and all of the domestic animals. These responses are mediated by immunoglobulin E (IgE) antibodies that bind to mast cells and cause release/synthesis of potent mediators. Clinical syndromes include naturally occurring asthma in humans and cats; atopic dermatitis in humans, dogs, horses, and several other species; food allergies; and anaphylactic shock. Experimental induction of asthma in mice, rats, monkeys, sheep, and cats has helped to reveal mechanisms of pathogenesis of asthma in humans. All of these species share the ability to develop a rapid and often fatal response to systemic administration of an allergen--anaphylactic shock. Genetic predisposition to development of allergic disease (atopy) has been demonstrated in humans, dogs, and horses. Application of mouse models of IgE-mediated allergic asthma has provided evidence for a role of air pollutants (ozone, diesel exhaust, environmental tobacco smoke) in enhanced sensitization to allergens.

Necrotizing granulomatous inflammation of the glans penis.

We describe the case of a 73-year-old man who presented with a 10-month history of an ulcerating lesion on the glans penis. Initially this was thought to be an invasive squamous cell carcinoma but a biopsy showed histological features consistent with necrotizing granulomatous inflammation. Extensive serological, immunological and microbiological tests only showed a positive antinuclear and perinuclear antineutrophil cytoplasmic antibodies indicating a possible autoimmune aetiology but an underlying systemic cause was not identified. Treatment with oral corticosteroids limited the inflammatory process but due to the gross destruction of the glans penis, he still required a glansectomy and split-skin graft reconstruction from which he recovered well. Although this patient ultimately required surgery for this rare presentation, this case highlights the differential diagnosis of penile ulceration (that transcends neoplasia) and the importance of performing and interpreting penile biopsies before undertaking potentially mutilating definitive surgery. 2016 BMJ Publishing Group Ltd.

There is no doubt about the beneficial effect of breastfeeding on the newborn's immune system. It is not fully elucidated what the differences are between the colostrum/milk of healthy and allergic mothers and how beneficial breastfeeding by an allergic mother is. The gene expression of selected cytokines was tested in cells isolated from colostra of healthy and allergic mothers using quantitative real-time PCR. Allergic phenotype was evident in colostral cells of allergic mothers: gene expressions of IL-4, IL-13 and EGF were increased and those of IFN-gamma decreased in comparison with colostral cells of healthy mothers. The allergic phenotype of the colostral cells of allergic mothers supporting the bias to a Th2 type response was found. It remains a question if a small number of these cells could influence the immature newborn immune system.

Alveolar macrophages from allergic lungs are not committed to a pro-allergic response and can reduce airway hyperresponsiveness following ex vivo culture

Summary Background We already demonstrated that adoptive transfer of alveolar macrophages (AMs) from non-allergic rats into AM-depleted allergic rats prevents airway hyperresponsiveness (AHR). We also showed that AMs from non-sensitized, but not from sensitized, allergy-prone rats can prevent AHR following allergen challenge in sensitized allergic animals, establishing the importance of rat immunological status on the modulation of AM functions and suggesting that an allergic lung environment alters AM functions. Objective We investigated how the activation of allergic AMs can be modulated to reinstitute them with their capacity to reduce AHR. Methods AMs from sensitized Brown Norway rats were cultured ex vivo for up to 18 h in culture media to deprogram them from the influence of the allergic lung before being reintroduced into the lung of AM-depleted sensitized recipient. AHR and cytokines in bronchoalveolar lavage (BAL) were measured following allergen challenge. AMs stimulated ex vivo with Bacillus Calmette-Guerin(BCG) were used as positive controls as BCG induces a T-helper type 1 activation in AMs. Results AMs ex vivo cultured for 4–18 h reduced AHR to normal level. Interestingly, pro-allergic functions of AMs were dampened by 18 h culture and they reduced AHR even after spending 48 h in an allergic lung microenvironment. Furthermore, transfer of cultured AMs caused an increase in the levels of IFN-γ and IL-12 in BAL when compared with their ovalbumin control. After 18 h of ex vivo culture, AMs expressed reduced levels of TNF, IL-1α, IL-6, and Arginase-2 mRNAs compared with freshly isolated AMs, suggesting that ex vivo culture exempted AMs from lung stimuli that affected their functions. Conclusions There is a significant crosstalk between lung microenvironment and AMs, affecting their functions. It is also the first report showing that sensitized AMs can be modulated ex vivo to reduce lung pro-allergic environment, opening the way to therapies targetting

Background Invasive Aspergillus infections are frequently seen in immunocompromised patients but arthritis is a rare complication of Aspergillus infections in the absence of immune suppressive therapy, trauma or surgical intervention. Case presentation A 17 years old male patient with arthritis and patellar osteomyelitis of the left knee whose further investigations revealed chronic granulomatous disease as the underlying disease is followed. Aspergillus fumigatus was isolated from the synovial fluid and the tissue samples cultures. He was treated with Amphotericin B deoxicolate 0.7 mg/kg/day. Also surgical debridement was performed our patient. Amphotericin B nephrotoxicity developed and the therapy switched to itraconazole 400 mg/day. Itraconazole therapy were discontinued at the 6th month. He can perform all the activities of daily living including. Conclusion We think that, chronic granulomatous disease should be investigated in patients who have aspergillar arthritis and osteomyelitis. PMID:12605719

Interaction between allergic asthma and atherosclerosis

PubMed Central

2015-01-01

Prior studies have established an essential role of mast cells in allergic asthma and atherosclerosis. Mast cell deficiency or inactivation protects mice from allergen-induced airway hyper-responsiveness and diet-induced atherosclerosis, suggesting that mast cells share pathologic activities in both diseases. Allergic asthma and atherosclerosis are inflammatory diseases that contain similar sets of elevated numbers of inflammatory cells in addition to mast cells in the airway and arterial wall, such as macrophages, monocytes, T cells, eosinophils, and smooth muscle cells. Emerging evidence from experimental models and human studies points to a potential interaction between the two seemingly unrelated diseases. Patients or mice with allergic asthma have a high risk of developing atherosclerosis or vice versa, despite the fact that asthma is a Th2-oriented disease, whereas Th1 immunity promotes atherosclerosis. In addition to the preferred Th1/Th2 responses that may differentiate the two diseases, mast cells and many other inflammatory cells also contribute to their pathogenesis by much more than just T cell immunity. Here we summarize the different roles of airway and arterial wall inflammatory cells and vascular cells in asthma and atherosclerosis, and propose an interaction between the two diseases, although limited investigations are available to delineate the molecular and cellular mechanisms by which one disease increases the risk of the other. Results from mouse allergic asthma and atherosclerosis models and from human population studies lead to the hypothesis that patients with atherosclerosis may benefit from anti-asthmatic medications, or that the therapeutic regimens targeting atherosclerosis may also alleviate allergic asthma.

Purpose Idiopathic granulomatous mastitis (IGM) is a rare chronic inflammatory disease of unknown etiology. The diagnosis of IGM requires that other granulomatous lesions in the breast be excluded. Tuberculous mastitis (TM) is also an uncommon disease that is often difficult to differentiate from IGM. The purpose of this study is to develop a new algorithm for the differential diagnosis and treatment of IGM and TM. Methods Medical records of 68 patients (58 with IGM and 10 with TM) between July 1999 and February 2009 were retrospectively reviewed. Results The mean age of the patients was 33.5 (IGM) and 40 (TM) years (p=0.018). The median follow-up was 84 months. Of the total 10 patients with TM, 5 patients had a history of pulmonary tuberculosis. The most common symptoms of the diseases were breast lump and pain. However, axillary lymphadenopathy was more seen in TM (50%) compared to IGM (20.6%) (p=0.048). TM showed more cancer-mimicking findings on radiologic study (p=0.028). In IGM, 48 patients (82.7%) underwent surgical wide excision and 21 patients (36.2%) were managed with corticosteroid therapy and antibiotics. All of the TM patients received anti-tuberculosis medications and 9 patients (90%) underwent wide excision. The mean treatment duration was 2.8 months in IGM and 8.4 months in TM. Recurrence developed in 5 patients (8.6%) in IGM and 1 patient (10%) in TM. Conclusion This study shows different characteristics between IGM and TM. The IGM patients were younger and had more mastalgia symptoms than the TM patients. Axillary lymphadenopathy was seen more often in TM patients. Half of the TM patients had pulmonary tuberculosis or tuberculosis lymphadenitis. Surgical wide excision might be both therapeutic and useful for providing an exact diagnosis. PMID:22493637

Studies addressing the relationship between pet keeping and development of asthma and allergies may be influenced by pet avoidance in families with a history of allergic disease. Following a cohort of 1019 children in Oslo till 10 years of age, we studied the association of pet keeping with socio-economic factors and allergic disease in the family. A family history of asthma and rhinoconjunctivitis was not significantly associated with pet ownership at birth or with pet removal by 10 years. Acquiring cats and dogs was less likely if the child had allergic rhinoconjunctivitis, whereas no association was seen with asthma (in any family member). Single parenthood increased the likelihood of acquiring a cat, smoking parents more often had cats or dogs, and having older siblings was associated with keeping dogs and other furry pets. Among 319 families reporting pet avoidance, 70% never had pets, 8% had given up pets, and 22% avoided a particular type of pet only. Twenty-four per cent of the parents failed to retrospectively report pet keeping during the child's first year of life. Overall, allergic rhinitis, but not asthma was associated with actual pet avoidance, whereas the strongest predictors for keeping pets were found to be socio-economic factors. Allergic disease in a child most often does not lead to the removal of the family's furry pet. Pet avoidance is associated with allergic symptoms, but not asthma. Socio-economic factors like parental education, single parenthood and smoking affects the families' decisions on pet keeping, including the type of pets the families will avoid or acquire. The large recall error demonstrated points to the need for prospective data regarding pet keeping.

Objectives Antimicrobial chemicals are used in a variety of household and personal care products. Exposure to antimicrobial household products has been hypothesized to lead to allergic diseases in children. Methods We investigated antimicrobial household product exposure and allergic symptoms in Korean children. An antimicrobial exposure (AE) score was derived. To examine the symptoms of allergic diseases (current wheeze, current rhinitis, and current eczema) in the past 12 months, we used a questionnaire based on the core module of the International Study of Asthma and Allergies in Children. Complete data for the analysis were available for 25,805 of the 35,590 (72.5%) children. Results The prevalence of current allergic diseases was as follows: wheeze, 5.6%; allergic rhinitis, 32.6%; and eczema, 17.7%. The mean (standard deviation) AE score was 14.3 (9.3) (range: 0-40). Compared with subjects with a low AE score (reference), subjects with a high AE score (fourth quartile) were more likely to have symptoms of wheezing and allergic rhinitis (adjusted odds ratio [aOR] for wheezing 1.24, 95% confidence interval [CI], 1.05-1.45, p for trend=0.24; aOR for allergic rhinitis 1.30, 95% CI, 1.20-1.40, p<0.01). Conclusions These findings suggest that frequent use of antimicrobial household products was associated with current wheeze and current allergic rhinitis. PMID:25420879

Granulomatous dermatitis has been associated with hematologic disorders, including the myelodysplastic syndromes. We describe the first case of granulomatous dermatitis associated with polycythemia vera, presenting as large erythematous nodules mimicking panniculitis. We also present the seventh case associated with myelodysplasia, with erythematous plaques on the face and neck, similar to a neutrophilic dermatosis. We consider it particularly interesting for dermatologists to be aware of this dermatosis as a nonspecific manifestation of various hematologic disorders. We suggest performing additional tests (complete blood count) to exclude the possibility that the skin manifestations are the initial sign of hematologic disease. Furthermore, we propose using the broader term, granulomatous dermatitis, to refer to these disorders as, although there are more reports of interstitial forms, cases with a more nodular presentation have also been published, and the importance of the diagnosis derives not from the subtype but from the relationship with an underlying disease.

Ocular allergy is an inflammatory response of the conjunctival mucosa that also affects the cornea and eyelids. Allergic conjunctivitis includes seasonal allergic conjunctivitis (SAC), perennial allergic conjunctivitis (PAC), vernal keratoconjunctivitis (VKC), atopic keratoconjunctivitis (AKC) and giant papillary conjunctivitis (GPC). In general, allergic conditions involve mast cell degranulation that leads to release of inflammatory mediators and activation of enzymatic cascades generating pro-inflammatory mediators. In chronic ocular inflammatory disorders associated with mast cell activation such as VKC and AKC constant inflammatory response is observed due to predominance of inflammatory mediators such as eosinophils and Th2-generated cytokines. Antihistamines, mast-cell stabilizers, non-steroidal anti-inflammatory agents, corticosteroids and immunomodulatory agents are commonly indicated for the treatment of acute and chronic allergic conjunctivitis. In recent years newer drug molecules have been introduced in the treatment of allergic conjunctivitis. This article reviews recent patents and emerging therapeutics in the treatment of allergic conjunctivitis. PMID:21171952

Antioxidant intakes in pregnancy may influence fetal immune programming and the risk of allergic disease. We investigated associations between maternal intakes of β-carotene, vitamin C, vitamin E, copper and zinc, and infant allergic outcomes. Antioxidant intakes of pregnant women (n = 420) assessed prospectively by a food frequency questionnaire, were examined in relation to allergic outcomes at 1 year of age (n = 300). The main relationships with allergic outcomes were seen with dietary vitamin C and copper. Specifically, higher maternal dietary vitamin C intake was associated with a reduced risk of any diagnosed infant allergic disease and wheeze. After adjustment for potential confounders the relationship with wheeze remained statistically significant. There was also an inverse linear relationship between vitamin C and food allergy. Higher dietary copper intake was associated with reduced risk of eczema, wheeze and any allergic disease. The relationship with wheeze and any allergic disease remained statistically significant in multivariate analysis, and there was also an inverse linear relationship between copper and food allergy. However, these relationships were only seen for nutrients present in food. There were no relationships between β-carotene, vitamin E or zinc and any allergic outcomes. In summary, this study suggests that maternal diet of fresh foods rich in vitamin C is associated with reduced risk of infant wheeze, and that copper intake is associated with reduced risk of several allergic outcomes.

Asparaginase is an important component of pediatric acute lymphoblastic leukemia (ALL) therapy. Unfortunately, this treatment is hampered by hypersensitivity reactions. In general, allergies - regardless of severity - cause complete inactivation of the drug. However, we report atypical allergic reactions without inactivation of asparaginase, here called allergic-like reactions. Patients with an allergic-like reaction, who were treated according to the Dutch Childhood Oncology Group ALL-11 or the CoALL 08-09 protocol, were described. The reactions were identified by continual measurement of asparaginase activity levels. Characteristics, including timing of occurrence, symptoms, grade, and the presence of antiasparaginase antibodies, were compared to those of real allergies. Fourteen allergic-like reactions occurred in nine patients. Five reactions were to PEGasparaginase and nine to Erwinia asparaginase. Allergic-like reactions occurred relatively late after the start of infusion compared to real allergies. Antibodies were absent in all but one patient with an allergic-like reaction, while they were detected in all patients with a real allergy. Symptoms and grade did not differ between the groups. Asparaginase was continued with the same formulation in six patients of whom four finished treatment with adequate activity levels. In conclusion, allergic-like reactions occur relatively late after the start of infusion and without antibodies. Despite these clinical differences, allergic-like reactions can only be distinguished from real allergies by continually measuring asparaginase activity levels. If clinically tolerated, formulations should not be switched in case of allergic-like reactions. Moreover, failure to recognize these reactions may lead to a less favorable prognosis if asparaginase therapy is terminated unnecessarily. © 2016 Wiley Periodicals, Inc.

Bilastine as a potential treatment in allergic rhinitis.

Kowal, Krzysztof; DuBuske, Lawrence

2014-01-01

Allergic rhinitis is a very frequent disease. H1 antihistamines have been used for treatment of allergic rhinitis for more than 5 decades. They differ in chemical structure, pharmacokinetics, pharmacodynamics, clinical efficacy and adverse effects. We performed a detailed analysis of all available publications concerning the new H1-antihistamine bilasitine. Bilastine, a piperidine derivative, is a novel potent H1 antihistamine. It is at least as potent as cetirizine or fexofenadine in in vitro studies. In animal studies it demonstrates dose-dependent antihistaminic and antiallergic effects. In humans its metabolism is not affected by age, gender or renal function but may be affected by coadministration of P glycoprotein inhibitors. Efficacy of bilastine in therapy of allergic rhinitis patients has been documented in several large controlled clinical trials showing bilastine being at least as effective as cetirizine or desloratadine. No significant suppressive effect on central nervous system could be demonstrated when bilastine was used in the recommended doses. Bilastine is a novel H1 antihistamine with anti-allergic properties which is highly effective in the treatment of symptoms of allergic rhinitis. It has a favorable pharmacokinetic and pharmacodynamic profile and is generally well tolerated.

Allergic rhinitis is more than just sneezing and an itchy nose. Complications of this disease are numerous and can have a significant impact, both mentally and physically. That is why it is important not only to detect, investigate and treat allergic rhinitis but also to actively identify potential complications. Mental functions such as learning, sleep and activity levels can deteriorate, and the eustachian tubes, sinuses and airway functions can be affected. Otitis, sinusitis and asthma are overrepresented among individuals who suffer from allergic rhinitis. This article highlights how allergic rhinitis can affect cognitive functions, and what consequences this can have on school performance, work and quality of life. Health professionals and school personnel need to increase their awareness of the ramifications of this disease and actively work to prevent deterioration in both academic achievement and workplace productivity.

We report a rare case of diffuse tracheo-bronchitis as a complication of Crohn's disease. A young man with a long-standing history of Crohn's enterocolitis initially presented with epigastric pain and melena. Upper endoscopy revealed erythematous, edematous, and friable mucosa with erosions, particularly in the pyloric channel, causing gastric outlet obstruction, and a nonbleeding ulcer in the corpus of stomach. Biopsy of these lesions showed chronic gastritis and a noncaseating epithelioid granuloma, consistent with active Crohn's disease. The patient was treated with a course of corticosteroids and the gastric symptoms resolved. A few months later, he developed fever, cough, hemoptysis, and rash. Bronchoscopy demonstrated a markedly thickened and very inflamed trachea with extensive friable, whitish lesions and ulcerations. Histology showed severe noncaseating granulomatous inflammation. The patient improved with a 6-week oral, followed by an additional 4-week inhaled, corticosteroid treatment. Since then, he has been doing well without relapse of pulmonary symptoms for 2 years.

Pregnancy may be complicated by new-onset or preexisting asthma and allergic rhinitis.This article reviews the recognition and management of asthma and allergic rhinitis during pregnancy, paying close attention to the general principles of allergy and use of asthma medication during pregnancy. Both allergic rhinitis and asthma can adversely affect both maternal quality of life and, in the case of maternal asthma, perinatal outcomes. Optimal management is thus important for both mother and baby. This article reviews the safety of asthma and allergy medications commonly used during pregnancy.

Corynebacterium species are increasingly recognized as important pathogens in granulomatous mastitis. Currently, there are no published treatment protocols for Corynebacterium breast infections. This study describes antimicrobial treatment options in the context of other management strategies used for granulomatous mastitis. Corynebacterium spp. isolated from breast tissue and aspirate samples stored from 2002 to 2013 were identified and determined to the species level using matrix-assisted laser desorption ionization–time of flight mass spectrometry (MALDI-TOF MS), 16S RNA sequencing, and rpoB gene targets. The MICs for 12 antimicrobials were performed using Etest for each isolate. Correlations of these with antimicrobial characteristics, choice of antimicrobial, and disease outcome were evaluated. Corynebacterium spp. from breast tissue and aspirate samples were confirmed in 17 isolates from 16 patients. Based on EUCAST breakpoints, Corynebacterium kroppenstedtii isolates (n = 11) were susceptible to seven antibiotic classes but resistant to β-lactam antibiotics. Corynebacterium tuberculostearicum isolates (n = 4) were multidrug resistant. Two nonlipophilic species were isolated, Corynebacterium glucuronolyticum and Corynebacterium freneyi, both of which have various susceptibilities to antimicrobial agents. Short-course antimicrobial therapy was common (median, 6 courses per subject; range, 1 to 9 courses). Patients with C. kroppenstedtii presented with a hot painful breast mass and underwent multiple surgical procedures (median, 4 procedures; range, 2 to 6 procedures). The management of Corynebacterium breast infections requires a multidisciplinary approach and includes culture and appropriate sensitivity testing to guide antimicrobial therapy. Established infections have a poor outcome, possibly because adequate concentrations of some drugs will be difficult to achieve in lipophilic granulomata. Lipophilic antimicrobial therapy may offer a therapeutic

Allergen Avoidance in Allergic Asthma

Cipriani, Francesca; Calamelli, Elisabetta; Ricci, Giampaolo

2017-01-01

Allergic asthma is the most frequent disease among the chronic respiratory disorders in pediatric age with an important social impact. In the last years, many efforts have been made to identify effective preventive approaches to get a better control of symptoms and to obtain the best future outcomes for the patients. In patients with allergic asthma triggered by the exposure to indoor allergens, the avoidance is the first intervention to prevent the appearance or the worsening of bronchial symptoms. This review article summarized the most recent evidence from literature about the efficacy of specific control interventions for the most important allergens. Even if a wide spectrum of interventions has been suggested and may help to reduce exposure to trigger allergy for sensitized patients suffering from respiratory allergy, evidence supporting the efficacy of these approaches is still weak and subject of controversy. However, the exposure control to specific airborne allergens is still widely recommended and may be effective as part of a holistic approach to reduce the severity of allergic respiratory symptoms in sensitized individuals.

Allergic asthma has a global prevalence, morbidity, and mortality. Many environmental factors, such as pollutants and allergens, are highly relevant to allergic asthma. The most important pathological symptom of allergic asthma is airway inflammation. Accordingly, the unique role of reactive oxygen species (ROS) had been identified as a main reason for this respiratory inflammation. Many studies have shown that inhalation of different allergens can promote ROS generation. Recent studies have demonstrated that several pro-inflammatory mediators are responsible for the development of allergic asthma. Among these mediators, endogenous or exogenous ROS are responsible for the airway inflammation of allergic asthma. Furthermore, several inflammatory cells induce ROS and allergic asthma development. Airway inflammation, airway hyper-responsiveness, tissue injury, and remodeling can be induced by excessive ROS production in animal models. Based on investigations of allergic asthma and ROS formation mechanisms, we have identified several novel anti-inflammatory therapeutic treatments. This review describes the recent data linking ROS to the pathogenesis of allergic asthma. PMID:28203435

Allergic diseases, such as asthma, allergic rhinitis, eczema, and food allergy, are preventable diseases. Primary prevention strategies of allergic diseases have been in scrutiny. Effective prevention strategies maybe started prenatally, postnatally, during infancy, and even during childhood. These guidelines have been prepared by the Philippine Society of Allergy, Asthma and Immunology and the Philippine Society for Pediatric Gastroenterology, Hepatology and Nutrition. They aim to provide evidence-based recommendations for the dietary primary prevention of allergic diseases in children. The primary audience of these guidelines is all healthcare practitioners who manage patients with potential allergic conditions. These guidelines are based on an exhaustive review of evidences, mostly systematic reviews, randomized controlled trials, and cohort studies. However, there are still many gaps in the evidence of dietary primary prevention of allergic diseases. PMID:28487842

Endocrine disruptors found in food contaminants enhance allergic sensitization through an oxidative stress that promotes the development of allergic airway inflammation

In the past few decades, there has been a significant increase in incidence of allergic diseases. The hygiene hypothesis may provide some clues to explain this rising trend, but it may also be attributable to other environmental factors that exert a proallergic adjuvant effects. However, there is limited information on the risks of developing allergic asthma and related diseases through the ingestion of environmental chemicals found in food contaminants. In the present study, we have shown that oral administration of tributyltin, used as a model environmental chemical, induced oxidative-stress status in the bronchial lymph node, mesenteric lymph node and spleen,more » but not in the lung, where the initial step of allergic asthma pathogenesis takes place. Mice exposed to tributyltin exhibited heightened Th2 immunity to the allergen with more severe airway inflammation. Tributyltin also induced Treg cells apoptosis preferentially over non-Treg cells. All these effects of tributyltin exposure were canceled by the administration of glutathione monoethyl ester. Meanwhile, tributyltin did not affect airway inflammation of mice transferred with allergen-specific Th2 cells. Collectively, these results suggest that tributyltin exerts its pathological effect during the sensitization phase through oxidative stress that enhances the development of allergic diseases. The current study dissects the pathogenic role of oxidative stress induced by oral exposure to an environmental chemical during the sensitization phase of allergic airway inflammation and would be important for developing therapeutics for prevention of allergic diseases. - Highlights: • Oral exposure to TBT exacerbates airway inflammation. • TBT induces oxidative stress in secondary lymphoid organs, but not in the lung. • TBT preferentially induces regulatory T cell apoptosis over non-Treg cells. • TBT does not enhance pre-existing airway inflammation in sensitized mice. • Chemicals in food

The guidelines on allergic rhinitis aim to update knowledge about the disease and care for affected patients. The initiative called "Allergic Rhinitis and its Impact on Asthma", initially published in 2001 and updated in 2008 and 2010, has been very successful in disseminating information and evidence, as well as providing a classification of severity and proposing a systemized treatment protocol. In order to include the participation of other medical professionals in the treatment of allergic rhinitis, it is important to develop algorithms that accurately indicate what should and can be done regionally. To update the III Brazilian Consensus on Rhinitis - 2012, with the creation of an algorithm for allergic rhinitis management. We invited 24 experts nominated by the Brazilian Association of Allergy and Immunology, Brazilian Association of Otorhinolaryngology and Head and Neck Surgery and Brazilian Society of Pediatrics to update the 2012 document. The update of the last Brazilian Consensus on Rhinitis incorporated and adapted the relevant information published in all "Allergic Rhinitis and its Impact on Asthma" Initiative documents to the Brazilian scenario, bringing new concepts such as local allergic rhinitis, new drugs and treatment evaluation methods. A flowchart for allergic rhinitis treatment has been proposed. Copyright © 2017. Published by Elsevier Editora Ltda.

Background Allergic rhinitis is the most common type of allergy worldwide. The accuracy of skin testing for allergic rhinitis is still debated. This health technology assessment had two objectives: to determine the diagnostic accuracy of skin-prick and intradermal testing in patients with suspected allergic rhinitis and to estimate the costs to the Ontario health system of skin testing for allergic rhinitis. Methods We searched All Ovid MEDLINE, Embase, and Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, CRD Health Technology Assessment Database, Cochrane Central Register of Controlled Trials, and NHS Economic Evaluation Database for studies that evaluated the diagnostic accuracy of skin-prick and intradermal testing for allergic rhinitis using nasal provocation as the reference standard. For the clinical evidence review, data extraction and quality assessment were performed using the QUADAS-2 tool. We used the bivariate random-effects model for meta-analysis. For the economic evidence review, we assessed studies using a modified checklist developed by the (United Kingdom) National Institute for Health and Care Excellence. We estimated the annual cost of skin testing for allergic rhinitis in Ontario for 2015 to 2017 using provincial data on testing volumes and costs. Results We meta-analyzed seven studies with a total of 430 patients that assessed the accuracy of skin-prick testing. The pooled pair of sensitivity and specificity for skin-prick testing was 85% and 77%, respectively. We did not perform a meta-analysis for the diagnostic accuracy of intradermal testing due to the small number of studies (n = 4). Of these, two evaluated the accuracy of intradermal testing in confirming negative skin-prick testing results, with sensitivity ranging from 27% to 50% and specificity ranging from 60% to 100%. The other two studies evaluated the accuracy of intradermal testing as a stand-alone tool for diagnosing allergic rhinitis, with

Objectives In patients with inflammatory bowel diseases (IBD), the presence of non-caseating mucosal granuloma is sufficient for diagnosing Crohn disease (CD) and may represent a specific immune response or microbial-host interaction. The cause of granulomas in CD is unknown and their association with the intestinal microbiota has not been addressed with high-throughput methodologies. Methods The mucosal microbiota from three different pediatric centers was studied with 454 pyrosequencing of the bacterial 16S rRNA gene and the fungal small subunit (SSU) ribosomal region in transverse colonic biopsy specimens from 26 controls and 15 treatment naïve pediatric CD cases. Mycobacterium avium subspecies paratuberculosis (MAP) was tested with real-time PCR. The correlation of granulomatous inflammation with C-reactive protein (CRP) was expanded to 86 treatment naïve CD cases. Results The CD microbiota separated from controls by distance based redundancy analysis (dbRDA; p=0.035). Mucosal granulomata found in any portion of the intestinal tract associated with an augmented colonic bacterial microbiota divergence (p=0.013). The granuloma based microbiota separation persisted even when research center bias was eliminated (p=0.04). Decreased Roseburia and Ruminococcus in granulomatous CD were important in this separation. However, principal coordinates analysis (PCoA) did not reveal partitioning of the groups. CRP levels above 1mg/dl predicted the presence of mucosal granulomata (OR: 28 [6–134.32]; 73% sensitivity, 91% specificity). Conclusions Granulomatous CD associates with microbiota separation and CRP elevation in treatment naïve children. However, overall dysbiosis in pediatric CD appears rather limited. Geographical/center bias should be accounted for in future multi-center microbiota studies. PMID:22699834

Non-pulmonary allergic diseases and inflammatory bowel disease: a qualitative review.

2014-08-28

While the etiological underpinnings of inflammatory bowel disease (IBD) are highly complex, it has been noted that both clinical and pathophysiological similarities exist between IBD and both asthma and non-pulmonary allergic phenomena. In this review, several key points on common biomarkers, pathophysiology, clinical manifestations and nutritional and probiotic interventions for both IBD and non-pulmonary allergic diseases are discussed. Histamine and mast cell activity show common behaviors in both IBD and in certain allergic disorders. IgE also represents a key immunoglobulin involved in both IBD and in certain allergic pathologies, though these links require further study. Probiotics remain a critically important intervention for both IBD subtypes as well as multiple allergic phenomena. Linked clinical phenomena, especially sinonasal disease and IBD, are discussed. In addition, nutritional interventions remain an underutilized and promising therapy for modification of both allergic disorders and IBD. Recommending new mothers breastfeed their infants, and increasing the duration of breastfeeding may also help prevent both IBD and allergic diseases, but requires more investigation. While much remains to be discovered, it is clear that non-pulmonary allergic phenomena are connected to IBD in a myriad number of ways and that the discovery of common immunological pathways may usher in an era of vastly improved treatments for patients.

Macrophage Transactivation for Chemokine Production Identified as a Negative Regulator of Granulomatous Inflammation Using Agent-Based Modeling.

Cellular activation in trans by interferons, cytokines, and chemokines is a commonly recognized mechanism to amplify immune effector function and limit pathogen spread. However, an optimal host response also requires that collateral damage associated with inflammation is limited. This may be particularly so in the case of granulomatous inflammation, where an excessive number and/or excessively florid granulomas can have significant pathological consequences. Here, we have combined transcriptomics, agent-based modeling, and in vivo experimental approaches to study constraints on hepatic granuloma formation in a murine model of experimental leishmaniasis. We demonstrate that chemokine production by non-infected Kupffer cells in the Leishmania donovani -infected liver promotes competition with infected KCs for available iNKT cells, ultimately inhibiting the extent of granulomatous inflammation. We propose trans-activation for chemokine production as a novel broadly applicable mechanism that may operate early in infection to limit excessive focal inflammation.

Nivolumab is a fully human IgG4 monoclonal antibody directed against programmed cell death protein 1 (PD-1). PD-1 inhibition allows T-cell activation and recruitment to destroy cancer cells. Checkpoint inhibitors have shown significant survival advantage and relatively low side-effects in comparison with conventional chemotherapy in several types of advanced cancer. Granulomatous cutaneous reactions have been reported showing sarcoidal and panniculitic morphology. Here we present a case of drug-induced lichenoid and granulomatous dermatitis after checkpoint inhibitor therapy observed in a 63-year-old male treated with nivolumab for advanced glioblastoma. This morphology has not been previously reported. We documented a high number of CD8+ T-cells within the lesions. Additionally, we review the side-effects observed with the use of checkpoint inhibitors, with special focus on cutaneous manifestations. © 2018 John Wiley & Sons A/S.

Ocular symptoms often accompany allergic rhinitis and can be as or even more bothersome for the patient than the actual nasal symptoms. Ocular manifestations of allergic rhinoconjunctivitis may result from both direct allergen-mediated mast cell stimulation on the surface of the eye and naso-ocular reflexes--histamine being one of the mediators of symptoms onset. An H1 antihistamine would be the first line treatment for allergic conjunctivitis. Since allergic conjunctivitis is always (or almost always) accompanied by nasal symptoms, a second-generation H1 antihistamine administered via oral route is the drug of choice for jointly managing both the nasal and the ocular symptoms--minimizing the impact of the effects inherent to first-generation H, antihistamine, including particularly drowsiness. Bilastine is a new H1 antihistamine with an excellent safety profile, developed for the treatment of allergic rhinoconjunctivitis and urticaria, with potency similar to that of cetirizine and desloratadine, and superior to that of fexofenadine. This new drug has been shown to be effective in controlling the ocular symptoms of allergic rhinoconjunctivitis.

We present a case of a 65-year-old woman who was previously diagnosed with idiopathic granulomatous myositis and treated with immunosuppressive therapy for the next 10 years before a clinical diagnosis of inclusion body myositis was made. A review of the previously performed muscle biopsy showed most of the cardinal myopathologic features of sporadic inclusion body myositis, in addition to the granuloma. Her clinical course was strongly suggestive of inclusion body myositis with selective asymmetric weakness of forearm flexor muscles and quadriceps. This report highlights the importance of correlating clinical picture with muscle pathology changes along with judicious use of magnetic resonance imaging and serological studies to establish a definite diagnosis.

Scope and impact of allergic rhinitis.

Allergic rhinitis is estimated to affect as many as 40 million people in the United States on a regular basis, and even more individuals who have occasional symptoms. The disease is associated with a considerable burden on the healthcare system, accounting for a total of $7.9 billion in direct and indirect costs in 1997, and with significant adverse effects on patients' quality of life, including disturbed sleep and impaired function at work and school. The pathophysiology of allergic rhinitis is complex, involving inflammatory mediators and immune cells that produce allergy symptoms via multiple mechanisms. The first principle of clinical management of patients with allergic rhinitis is avoidance of exposure to allergens, but this measure can be very difficult, and most patients require pharmacotherapy. Allergy vaccine therapy may be an appropriate and necessary option in selected patients with allergies refractory to other treatment modalities.

Contact allergic gastritis: an underdiagnosed entity?

Only a few cases of contact allergic gastritis in patients with nickel allergy have been reported. We report a case of probable contact-allergic gastritis in a 46-year-old woman. Clinical examination revealed lichenoid mucosal lesions of the gums adjacent to bridges and crowns that had been implanted several weeks back. Since implantation, the patient had suffered from gastrointestinal complaints (including stomach pain). Gastroscopy showed eosinophilic gastritis. Patch testing done under the diagnosis of contact allergic stomatitis showed positive reactions to: gold sodium thiosulphate; manganese (II) chloride; nickel (II) sulphate; palladium chloride; vanadium (III) chloride and zirconium (IV) chloride. The crowns and bridge contained gold, palladium and zirconium chloride, hence they were replaced by titan-based dentition. Shortly after replacing the artificial dentition, all gastrointestinal symptoms resolved spontaneously without further treatment. Delayed-type allergy against the components of artificial dentition seemed to be the cause of gastritis. PMID:23192576

Idiopathic granulomatous mastitis (IGM) is an uncommon chronic inflammatory lesion of the breast with an uncertain optimal treatment regimen, the physical examination, and radiologic features of which may be confused with breast carcinoma. In this study, we aimed to describe the clinicopathologic characteristics of 33 patients who admitted to our breast policlinic and took the diagnosis of granulomatous (idiopathic and non-idiopathic) mastitis, and report the place of corticosteroids and the timing of surgery in the treatment of patients with IGM. The clinical features of 33 patients who presented to our breast policlinic with the complaint of breast mass and reached the final diagnosis of GM between March 2005 and October 2009 were reported. The most common symptoms were mass (n: 27) and pain (n: 11). Ultrasonography (USG) and biopsy were performed in all of the patients. Mammography (MMG) was performed in 9, and magnetic resonance imaging (MRI) in 10 patients. The diagnosis of idiopathic lobular granulomatous mastitis (ILGM) was made in 25 patients and tuberculous mastitis (non-idiopathic GM) in the remaining 8 patients. Twenty-four patients received steroid treatment except one who was pregnant. After giving birth, she also received steroids. One of the patients who developed recurrence after 11 months repeated the steroid therapy. Eight patients with tuberculous mastitis were placed on a regimen of antituberculosis therapy for 6 months. In the diagnosis of IGM, physical examination, USG, MMG, and even MRI alone may sometimes not be enough. They should be discussed altogether and the treatment should begin after definitive histopathologic result. Fine needle aspiration biopsy for cytology will result in a high level of diagnostic accuracy, however, core biopsy will reinforce the exact result. Corticosteroid therapy has been shown to be efficacious for IGM, but in the existence of complications such as abscess formation, fistulae, and persistent wound infection

Patient: Female, 23 Final Diagnosis: Chronic granulomatous disease Symptoms: Fever • shortness of breath Medication: — Clinical Procedure: Bronchoscopy Specialty: Pulmonology Objective: Unusual clinical course Background: Chronic Granulomatous Disease (CGD) is a rare immunodeficiency disease caused by a genetic defect in the NADPH (nicotinamide adenine dinucleotide phosphate) oxidase enzyme, resulting in increased susceptibility to bacterial and fungal infections. The inheritance can be X-linked or autosomal recessive. Patients usually present with repeated infections early in life. We present an unusual case of a 23-year-old patient diagnosed with CGD. Case Report: A 23-year-old white woman with no previous history of recurrent infections presented with complaints of fever, shortness of breath, and diffuse myalgia. She had been treated twice for similar complaints recently, but without resolution. She was febrile, tachypneic, tachycardic, and hypoxic at presentation. Physical examination revealed diffuse inspiratory rales. Laboratory results showed leukocytosis. Her initial chest X-ray and CT chest showed reticular nodular interstitial lung disease pattern. Despite being on broad-spectrum antibiotics for 5 days, she continued to require supplemental oxygen and continued to be tachypneic, with minimal activity. Initial diagnostic tests, including bronchoscopy with biopsy and lavage, did not reveal a diagnosis. She then underwent a video-assisted thoracoscopic surgery (VATS) lung biopsy. The biopsy slides showed suppurative granulomatous inflammation affecting greater than 50% of the parenchymal lung surface. Fungal hyphae consistent with Aspergillus were present in those granulomas. A diagnosis of CGD was made and she was started on Voriconazole. She improved with treatment. Her neutrophil burst test showed negative burst on stimulation, indicating phagocytic dysfunction consistent with CGD. Autosomal recessive CGD was confirmed by genetic testing. Conclusions

Transcription and translation of the chemokines RANTES and MCP-1 in nasal polyps and mucosa in allergic and non-allergic rhinopathies.

The pathogenetic findings of rhinopathies show an increase in infiltrating cells including eosinophils. RANTES is a beta chemokine in which the cysteines are adjacent (C-C), and it attracts and activates eosinophil. We hypothesize that RANTES is locally produced within the nasal polyp microenvironment and is responsible for the inflammatory cell recruitment present in nasal polyposis. To test this hypothesis, we evaluated nasal polyps and mucosa from allergic and control, non-allergic patients for RANTES content. The relative levels of RANTES and MCP-1 protein in tissue homogenates were quantified using enzyme-linked immunosorbent assay technology, and quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) tests for RANTES and MCP-1 mRNA expression were performed. The results indicate that RANTES expression and production increase in nasal mucosa (septal and turbinate portions) of allergic patients compared to the same mucosa in non-allergic patients. In allergic patients, RANTES levels of nasal polyp homogenates were nearly 12-fold higher than the RANTES levels in mucosa homogenate. In this study, we hypothesize that the particular anatomic structure and physiologic function of the turbinates are more involved in the pathogenesis of rhinitis and may undergo polypoid degeneration in allergic rhinitis than any other anatomical structure of the nose. Our data suggest that RANTES is more involved than MCP-1 in recruiting inflammatory cells in rhinological disease and may reflect the degree of local inflammation as consequence of the specific chemoattractant properties of RANTES. The level of RANTES in nasal polyps could be important in the development of the pathological state.

The hygiene hypothesis proposes that reduced exposure to infections in early life increases the risk of developing allergic conditions including allergic rhinitis. We examined the association between markers of the hygiene hypothesis and allergic rhinitis that developed before 7 years of age and allergic rhinitis that developed after 7 years of age. The Tasmanian Longitudinal Health Study (TAHS) is a population-based cohort (n=8583) study of respiratory disease. Participants have been followed from 7 to 44 years of age. Information on potential risk factors, allergies and respiratory symptoms was collected longitudinally. Using multi-nomial logistic regression, exposure to siblings, infections, tonsillectomy and farm residence during childhood were examined as risk factors for allergic rhinitis that developed before or after 7 years of age. All analyses were adjusted for gender, maternal and paternal atopy, mother's age at participant's birth, paternal socio-economic status in 1968 and personal socio-economic status in 2004. Greater cumulative exposure to siblings before the age of 2 years was strongly inversely associated with early onset allergic rhinitis (<1 year sib exposure: OR=0.6, 95% CI 0.3-1.0; 1-3 years sib exposure: OR=0.6, 95% CI 0.4-0.9; >3 years sib exposure: OR=0.4, 95% CI 0.3-0.8) less so with later onset allergic rhinitis. The risk of early onset allergic rhinitis decreased with increasing viral infections (OR=0.7, 95% CI 0.5-0.9) during childhood. Having a tonsillectomy before 7 years of age increased the risk of early onset allergic rhinitis (OR=1.7, 95% CI 1.2-2.5). None of these factors was associated with later onset allergic rhinitis. Exposures relevant to the hygiene hypothesis were important predictors for the development of early onset but less so for later onset allergic rhinitis. The exact mechanisms by which siblings and infections protect against allergic rhinitis are unclear. The stronger findings for earlier onset allergic rhinitis

Granulomas are collections of histiocytes that develop as an inflammatory response to bacterial and fungal infections, as well as foreign substances. We discuss here the case of a 49-year-old male who presented with a penile and scrotal mass with granulomatous inflammation, after application of a topical cream for enhancement of erectile function. While granuloma formation can often be seen with penile injections, this case presents the rare development of a foreign body granuloma after topical cream application on the penis and scrotum.

To explore the relationship between allergic rhinitis (AR) and personality traits in nonpsychiatric population of allergic status. Subjects were assigned to the allergic (84 cases) or nonallergic health group (37 cases) on the basis of skin prick test (SPT) and allergic symptoms. The psychological aspects of subjects were assessed by using the minnesota multiphasic personality inventory (MMPI). The allergic group scored higher than the nonallergic group on five clinical scales, hypochondriasis (Hs), depression (D), hysteria (Hy), hypomania (Ma), social introversion (Si), and one research scale manifest anxiety scale (Mas). The differences were significant (t value was respectively 2.169, 2.711, 2.010, 2.577, 2.390 and 2.196, all P < 0.05). In addition, the grade of resultant skin wheal was positively correlated with T scores on the Hs, Hy, psychopathic deviance (Pd) and psychasthenia (Pt). The r value was 0.366, 0.449, 0.345 and 0.355 respectively (all P < 0.05). Subjects with AR show poorer psychological functioning, indicating the close relationship between AR and psychological status.

The National Health Interview Survey (NHIS) was used to obtain information on days lost from work and lost productivity due to allergic rhinitis. Wage estimates for occupations obtained from the Bureau of Labor Statistics (BLS) were used to calculate the costs. Productivity losses associated with a diagnosis of allergic rhinitis in the 1995 NHIS were estimated to be $601 million. When additional survey information on the use of sedating over-the-counter (OTC) allergy medications, as well as workers' self-assessments of their reduction in at-work productivity due to allergic rhinitis, were considered, the estimated productivity loss increased dramatically. At-work productivity losses were estimated to range from $2.4 billion to $4.6 billion. Despite the inherent difficulty of measuring productivity losses, our lowest estimate is several times higher than previous estimates of the indirect medical costs associated with allergic rhinitis treatment. The most significant productivity losses resulted not from absenteeism but from reduced at-work productivity associated with the use of sedating OTC antihistamines.

Molecular diagnosis of chronic granulomatous disease.

Patients with chronic granulomatous disease (CGD) suffer from recurrent, life-threatening bacterial and fungal infections of the skin, the airways, the lymph nodes, liver, brain and bones. Frequently found pathogens are Staphylococcus aureus, Aspergillus species, Klebsiella species, Burkholderia cepacia and Salmonella species. CGD is a rare (∼1:250 000 births) disease caused by mutations in any one of the five components of the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase in phagocytes. This enzyme generates superoxide and is essential for intracellular killing of pathogens by phagocytes. Molecular diagnosis of CGD involves measuring NADPH oxidase activity in phagocytes, measuring protein expression of NADPH oxidase components and mutation analysis of genes encoding these components. Residual oxidase activity is important to know for estimation of the clinical course and the chance of survival of the patient. Mutation analysis is mandatory for genetic counselling and prenatal diagnosis. This review summarizes the different assays available for the diagnosis of CGD, the precautions to be taken for correct measurements, the flow diagram to be followed, the assays for confirmation of the diagnosis and the determinations for carrier detection and prenatal diagnosis. © 2013 British Society for Immunology.

Protothecal granulomatous meningoencephalitis in a dog.

A case of central nervous system protothecosis in a dog is reported. A three-year-old male Maremma sheepdog was referred with a two month history of diarrhoea associated with progressive tetraparesis, depression and right circling. Stupor, severe proprioceptive deficits, bilateral decreased thoracic limb flexor reflexes and bilateral deficit of the menace reaction were detected on neurological examination and a multi-focal neurological localisation was suspected. Histopathological evaluation revealed multi-focal granulomatous foci in the thalamus, hippocampus and caudal brainstem containing numerous oval-rounded organisms with a thick, periodic acid-Schiff-positive and Gomori's methenamine silver-positive cell wall, a basophilic cytoplasm and one nucleus. Scattered sporangia containing two to four endospores were also observed. Morphological features were consistent with Prototheca species. Ultrastructurally, numerous degenerated algae were present within macrophages mainly lacking nuclei and cytoplasmic organelles. Generally, protothecosis in dogs is characterised by systemic signs because of a multi-organ involvement, and haemorrhagic colitis or ophthalmologic signs are the most frequent presenting signs. However, protothecosis should be added, also in Europe, to the list of the differential diagnoses in adult dogs with a multi-focal neurological localisation even in absence of other clinical signs.

Allergic rhinitis has become the most frequent chronic disease of upper airways and its prevalence is increasing importantly in countries with systems of western life. To determine the prevalence of allergic rhinitis and its subtypes in inhabitants of Durango, Mexico. Through a descriptive, cross-sectional study, 1,320 inhabitants of Durango were studied. They were chosen randomly and accepted voluntarily to participate. A modification of the Middleton diary symptom questionnaire was used as a tool to determine the prevalence. The prevalence of allergic rhinitis in the general population was of 7.6% (95% CI 6.2-9.2). The prevalence of seasonal rhinitis was of 5.5% (95% CI 4.4-6.9), of perennial rhinitis, 2.1% (95% CI 1.4-3.0), for medical diagnosis, 4.3% (95% CI 3.4-5.8), and for survey, 3.3% (95% CI 2.4-4.4). The highest frequency was found in persons of 5-9 years old (12.5%) and in women (5.1%). The prevalence of allergic rhinitis in Durango, Mexico, is similar to the national mean prevalence, but lower than that reported in developed countries.

Previous reports suggest that parents especially mothers of food-allergic children may have increased anxiety. Studies with an appropriate control group have not been undertaken, and the determinants of such anxiety are not known. We compared measures of anxiety and stress in mothers of food-allergic children and atopic non-food-allergic children, with anxiety and stress in mothers of children with no chronic illness. Cross-sectional study of mothers attending a hospital appointment for their 8- to 16-year-old child. Mothers of children with food allergy, asthma but no food allergy or no chronic illness completed questionnaires including State-Trait Anxiety Inventory, Perceived Stress Scale and measures of anxiety and psychologic adjustment in their child. Forty mothers of food-allergic children, 18 mothers of asthmatic children without food allergy and 38 mothers of children with no chronic illness (controls) were recruited. Mothers of food-allergic children showed increased state anxiety – median anxiety score 38.0 (IQR 30.0, 44.0) food allergy, 27.0 (22.0, 40.0) control p = 0.012; and increased stress – median stress score 18.5 (12.0, 22.0) food allergy, 14.0 (7.5, 19.5)control p = 0.035. No significant differences were seen between mothers in the asthmatic group and controls. In multivariate analysis, previous food anaphylaxis(p = 0.008) and poorly controlled asthma (p = 0.004) were associated with increased maternal anxiety. Child anxiety and adjustment did not differ between food-allergic and control groups. Mothers of food-allergic children have increased anxiety and stress compared with mothers of children with no chronic illness. Anaphylaxis and poorly controlled asthma are associated with maternal anxiety.

Exposure to particulate hexavalent chromium exacerbates allergic asthma pathology

DOE Office of Scientific and Technical Information (OSTI.GOV)

Schneider, Brent C.; Department of Pharmacology and Physiology, The George Washington University, Washington, DC 20037; Constant, Stephanie L.

Airborne hexavalent chromate, Cr(VI), has been identified by the Environmental Protection Agency as a possible health threat in urban areas, due to the carcinogenic potential of some of its forms. Particulate chromates are produced in many different industrial settings, with high levels of aerosolized forms historically documented. Along with an increased risk of lung cancer, a high incidence of allergic asthma has been reported in workers exposed to certain inhaled particulate Cr(VI) compounds. However, a direct causal association between Cr(VI) and allergic asthma has not been established. We recently showed that inhaled particulate Cr(VI) induces an innate neutrophilic inflammatory responsemore » in BALB/c mice. In the current studies we investigated how the inflammation induced by inhaled particulate Cr(VI) might alter the pathology of an allergic asthmatic response. We used a well-established mouse model of allergic asthma. Groups of ovalbumin protein (OVA)-primed mice were challenged either with OVA alone, or with a combination of OVA and particulate zinc chromate, and various parameters associated with asthmatic responses were measured. Co-exposure to particulate Cr(VI) and OVA mediated a mixed form of asthma in which both eosinophils and neutrophils are present in airways, tissue pathology is markedly exacerbated, and airway hyperresponsiveness is significantly increased. Taken together these findings suggest that inhalation of particulate forms of Cr(VI) may augment the severity of ongoing allergic asthma, as well as alter its phenotype. Such findings may have implications for asthmatics in settings in which airborne particulate Cr(VI) compounds are present at high levels. -- Highlights: ► Allergic asthma correlated with exposure to certain inhaled particulate chromates. ► Direct causal association between Cr(VI) and allergic asthma not established. ► Cr exacerbated pathology and airway hyperresponsiveness in an OVA-challenged mouse. �

Allergic manifestations of contact lens wearing.

Solomon, Abraham

2016-10-01

Contact lens-induced papillary conjunctivitis (CLPC) is a common ocular allergic disease in contact lens wearers. In its more severe form, it can cause giant papillary conjunctivitis, resulting in contact lens intolerance and the need to discontinue the use of contact lenses. This review presents the pathogenesis, clinical manifestations and management guidelines of this common disorder. Different types of contact lenses are associated with differences in the severity of CLPC. Refitting patients with silicone hydrogel contact lenses or with daily disposable contact lenses may improve the signs and symptoms of CLPC. The recent introduction of the topical immunomodulatory agent tacrolimus in other severe allergic eye diseases may apply in suppressing the allergic inflammation in CLPC as well. CLPC is a common ocular disorder in contact lens wearers, with a significant impact on the quality of vision. It should be promptly recognized by healthcare practitioners and managed by modifications of the types and wearing schedules of contact lenses, as well as novel treatment options with topical immunomodulators.

Rhinoviruses, Allergic Inflammation, and Asthma

Summary Viral infections affect wheezing and asthma in children and adults of all ages. In infancy, wheezing illnesses are usually viral in origin, and children with more severe wheezing episodes are more likely to develop recurrent episodes of asthma and to develop asthma later in childhood. Children who develop allergen-specific immunoglobulin E (allergic sensitization), and those who wheeze with rhinoviruses (HRV) are at especially high risk for asthma. In older children and adults, HRV infections generally cause relatively mild respiratory illnesses and yet contribute to acute and potentially severe exacerbations in patients with asthma. These findings underline the importance of understanding the synergistic nature of allergic sensitization and infections with HRV in infants relative to the onset of asthma and in children and adults with respect to exacerbations of asthma. This review discusses clinical and experimental evidence of virus/allergen interactions and evaluates theories which relate immunologic responses to respiratory viruses and allergens to the pathogenesis and disease activity of asthma. Greater understanding of the relationship between viral respiratory infections, allergic inflammation, and asthma is likely to suggest new strategies for the prevention and treatment of asthma.

Several authors have commented upon the skills of detection required in making a diagnosis of allergic contact dermatitis. Here, we emphasise the search for clues in a systematic manner. We describe four stages as part of a systematic method for diagnosing allergic contact dermatitis. Firstly, elimination (or inclusion) of non-allergic diagnoses. Secondly, perception: the pre-patch test diagnosis and the 'three scenarios' principle. Thirdly, detection: optimising the sensitivity of the patch test process. Fourthly, deduction: diagnosing allergic contact dermatitis by associating the dermatitis with the allergen exposure. We further compare and contrast the pre-patch test history and examination with the markedly different one ('microhistory' and 'microexamination') used after patch testing. The importance of knowledge of contact dermatitis literature is emphasised with a review of recent publications. Finally, we also highlight the use of contact allergy profiling as an investigative tool in the diagnosis of allergic contact dermatitis.

[Prevention of allergic diseases in childhood: from theory to reality].

2016-06-01

Allergic diseases have an increasing worldwide prevalence and a great impact on the health related costs. The research is focused on the study of etiological and risk factors of allergic diseases that can potentially be modified with primary, secondary and tertiary prevention strategies. Many of these measures do not have a definitively proven effect taking place in a controlled context different to what happens in real life. This paper aims to review the latest evidence on prevention of allergic diseases considering certainties and unresolved issues and focuses mainly on environmental, dietary, pharmacological and immunological preventive strategies for different levels of prevention. It is imperative to have a better understanding of genetic and environmental factors that cause allergic diseases to optimize preventive measures that are effective in reversing the increasing trend in the prevalence of allergic illnesses in childhood.

Background Exposure to the synthetic antimicrobial chemical, triclosan, used in personal care products, has been hypothesized to lead to allergic disease. We investigated whether triclosan exposure was associated with allergic sensitization and symptoms in 10-year old Norwegian children. Methods Urinary concentrations of triclosan were measured in one first morning void from 623 children, collected 2001– 2004. Logistic regression models, controlling for urine specific gravity, parental allergic disease, maternal education, and household income, were fitted for allergic sensitization (either skin prick test positivity or serum specific IgE ≥0.35 kU/L to at least one of 15 evaluated inhalant and food allergens), current rhinitis, and current asthma (questionnaire and exercise challenge test). Results The adjusted odds ratio (aOR) for allergic sensitization among those in the fourth quartile of triclosan concentration was 2.0 (95% confidence interval (CI): 1.1, 3.4) compared with the reference group (< the limit of detection) and the aOR per log10 unit increase in triclosan was 1.2 (95% CI: 1.0, 1.4). The aOR for current rhinitis was 1.9 (95% CI: 1.1, 3.4) for the fourth quartile and 1.2 (95% CI:0.97, 1.4) per log10 unit increase in triclosan. Conclusion Triclosan concentrations were associated with allergic sensitization, especially inhalant and seasonal allergens rather thanfood allergens. Current rhinitis was associated with the highest levels of triclosan, whereas no association was seen for current asthma. These results are consistent with recent findings in other studies and provide additional evidence for an association between triclosan and allergy. PMID:23146048

Therapeutic strategies for allergic diseases

Many drugs are now in development for the treatment of atopic diseases, including asthma, allergic rhinitis and atopic dermatitis. These treatments are based on improvements in existing therapies or on a better understanding of the cellular and molecular mechanisms involved in atopic diseases. Although most attention has been focused on asthma, treatments that inhibit the atopic disease process would have application to all atopic diseases, as they often coincide. Most of the many new therapies in development are aimed at inhibiting components of the allergic inflammatory response, but in the future there are real possibilities for the development of preventative and even curative treatments.

There is conflicting evidence on the protective role of breastfeeding in relation to the development of allergic sensitisation and allergic disease. Studies vary in methodology and definition of outcomes, which lead to considerable heterogeneity. Human milk composition varies both within and between individuals, which may partially explain conflicting data. It is known that human milk composition is very complex and contains variable levels of immune active molecules, oligosaccharides, metabolites, vitamins and other nutrients and microbial content. Existing evidence suggests that modulation of human breast milk composition has potential for preventing allergic diseases in early life. In this review, we discuss associations between breastfeeding/human milk composition and allergy development. PMID:28817095

Allergic reactions to Anisakis found in fish.

PubMed

Nieuwenhuizen, Natalie E; Lopata, Andreas L

2014-08-01

The food-borne parasite Anisakis is an important hidden food allergen. Anisakis is a parasitic nematode which has a third-stage larval form that infects mainly fish, and ingestion of contaminated seafood can result in severe allergic reactions. Symptoms experienced due to exposure to this parasite include gastrointestinal disorders, urticaria, dermatitis, asthma and even anaphylaxis. Accurate prevalence data of allergic sensitisation to Anisakis are difficult to estimate due to the lack of well-designed population-based studies. Current diagnostic approaches rely on the detection of serum IgE antibodies to allergenic proteins, which however demonstrate considerable immunological cross-reactivity to other invertebrate allergens. While exposure to this parasite seems to increase due to the increasing consumption of seafood worldwide, the immunology of infection and allergic sensitization is not fully understood.

To analyse the most recently published studies on the prevalence of allergic conjunctivitis alone or in association with allergic rhinitis, and the clinical and demographic aspects of the disease. Allergic conjunctivitis or conjunctival symptoms are present in 30-71% of patients with allergic rhinitis. Allergic conjunctivitis alone has been estimated in 6-30% of the general population and in up to 30% in children alone or in association with allergic rhinitis. Seasonal allergic conjunctivitis is the most frequent form; however, studies from tertiary, ophthalmology referral centers report that the chronic forms, such as vernal and atopic keratoconjunctivitis, are the most frequently seen by ophthalmologists. A recent large survey performed at a national level involving 304 ophthalmologists showed that the majority of patients with allergic conjunctivitis suffer annually of few episodes of mild ,intermittent conjunctivitis. However, 30% of patients are affected by frequent episodes with intense and persistent symptoms. Treatment is frequently not appropriate. Even though allergic conjunctivitis is often associated to allergic rhinitis, epidemiology studies frequently do not include specific ophthalmological evaluations. An understanding of allergic conjunctivitis disease, its prevalence, demographics and treatment paradigms will provide important information towards understanding its pharmacoeconomics and burden on the national health systems.

Pediatric asthma is heterogeneous with phenotypes that reflect differing underlying inflammation and pathophysiology. Little is known about the national prevalence of certain obesity and allergy related asthma phenotypes or associated characteristics. We therefore assessed the national prevalence, risk factors, and parent-reported severity of four asthma phenotypes: not-allergic-not-obese, allergic-not-obese, obese-not-allergic, and allergic-and-obese. We analyzed data from the 2007-2008 National Survey of Children's Health (NSCH) of 10-17 year-olds with parent-reported asthma. We described sociodemographic and health risk factors of each phenotype and then applied logistic and ordinal regression models to identify associated risk factors and level of severity of the phenotypes. Among 4,427 children with asthma in this NSCH cohort, the association between race and phenotype is statistically significant (p<0.0001); white children with asthma were most likely to have allergic-not-obese asthma while black and Hispanic children with asthma were most likely to have the obese-non-allergic phenotype (p<0.001). ADD/ADHD was more likely to be present in allergic-not-obese children (OR 1.50, CI 1.14-1.98, p = 0.004). The phenotype with the highest risk for more severe compared to mild asthma was the obese-and-allergic asthma phenotype (OR 3.34, CI 2.23-5.01, p<0.001). Allergic-not-obese asthma comprised half of our studied asthma phenotypes, while obesity-related asthma (with or without allergic components) comprised one-fifth of asthma phenotypes in this cohort representative of the U.S. Children with both obese and allergic asthma are most likely to have severe asthma. Future management of childhood asthma might consider more tailoring of treatment and management plans based upon different childhood asthma phenotypes.

2002-01-01

Aims: To investigate the effect of breast feeding on allergic disease in infants up to 2 years of age. Methods: A birth cohort of 4089 infants was followed prospectively in Stockholm, Sweden. Information about various exposures was obtained by parental questionnaires when the infants were 2 months old, and about allergic symptoms and feeding at 1 and 2 years of age. Duration of exclusive and partial breast feeding was assessed separately. Symptom related definitions of various allergic diseases were used. Odds ratios (OR) and 95% confidence intervals (CI) were estimated in a multiple logistic regression model. Adjustments were made for potential confounders. Results: Children exclusively breast fed during four months or more exhibited less asthma (7.7% v 12%, ORadj = 0.7, 95% CI 0.5 to 0.8), less atopic dermatitis (24% v 27%, ORadj = 0.8, 95% CI 0.7 to 1.0), and less suspected allergic rhinitis (6.5% v 9%, ORadj = 0.7, 95% CI 0.5 to 1.0) by 2 years of age. There was a significant risk reduction for asthma related to partial breast feeding during six months or more (ORadj = 0.7, 95% CI 0.5 to 0.9). Three or more of five possible allergic disorders—asthma, suspected allergic rhinitis, atopic dermatitis, food allergy related symptoms, and suspected allergic respiratory symptoms after exposure to pets or pollen—were found in 6.5% of the children. Exclusive breast feeding prevented children from having multiple allergic disease (ORadj = 0.7, 95% CI 0.5 to 0.9) during the first two years of life. Conclusion: Exclusive breast feeding seems to have a preventive effect on the early development of allergic disease—that is, asthma, atopic dermatitis, and suspected allergic rhinitis, up to 2 years of age. This protective effect was also evident for multiple allergic disease. PMID:12456543

Constitution factor plays an important role in the occurrence, development, and transformation of diseases. The occurrence of allergic diseases is mainly caused by the disorganized physiological function and suitability regulation of patients, except for their exposure to outside allergens. Moreover, it represents susceptibility and hypersensitivity to allergens. The current study expresses the concept of allergic constitution from the perspective of Chinese medicine (CM) and presents the criterion of allergic constitution. In addition, the distribution of allergic constitution in population, its factors, and its relation to health-related quality of life (HRQOL) were investigated. The HRQOL scores of allergic constitution were found to be lower than those of the Pinghe constitution. After making a study on the gene expression profile of allergic constitution, the characteristics of up-regulated or down-regulated genes were found. Finally, CM drug was researched and developed to improve allergic constitution. Based on clinical trials and animal experiments, CM is found to have good regulatory effects on allergic constitution.

Background Allergic rhinitis, allergic dermatitis, and food allergy are extremely common diseases, especially among children, and are frequently associated to each other and to asthma. Smoking is a potential risk factor for these conditions, but so far, results from individual studies have been conflicting. The objective of this study was to examine the evidence for an association between active smoking (AS) or passive exposure to secondhand smoke and allergic conditions. Methods and Findings We retrieved studies published in any language up to June 30th, 2013 by systematically searching Medline, Embase, the five regional bibliographic databases of the World Health Organization, and ISI-Proceedings databases, by manually examining the references of the original articles and reviews retrieved, and by establishing personal contact with clinical researchers. We included cohort, case-control, and cross-sectional studies reporting odds ratio (OR) or relative risk (RR) estimates and confidence intervals of smoking and allergic conditions, first among the general population and then among children. We retrieved 97 studies on allergic rhinitis, 91 on allergic dermatitis, and eight on food allergy published in 139 different articles. When all studies were analyzed together (showing random effects model results and pooled ORs expressed as RR), allergic rhinitis was not associated with active smoking (pooled RR, 1.02 [95% CI 0.92–1.15]), but was associated with passive smoking (pooled RR 1.10 [95% CI 1.06–1.15]). Allergic dermatitis was associated with both active (pooled RR, 1.21 [95% CI 1.14–1.29]) and passive smoking (pooled RR, 1.07 [95% CI 1.03–1.12]). In children and adolescent, allergic rhinitis was associated with active (pooled RR, 1.40 (95% CI 1.24–1.59) and passive smoking (pooled RR, 1.09 [95% CI 1.04–1.14]). Allergic dermatitis was associated with active (pooled RR, 1.36 [95% CI 1.17–1.46]) and passive smoking (pooled RR, 1.06 [95% CI 1.01–1

Bilastine: in allergic rhinitis and urticaria.

PubMed

Carter, Natalie J

2012-06-18

Bilastine is an orally administered, second-generation antihistamine used in the symptomatic treatment of seasonal or perennial allergic rhinoconjunctivitis and urticaria. In two well designed phase III trials, 14 days' treatment with bilastine was associated with a significantly lower area under the effect curve (AUEC) for the reflective total symptom score (TSS) than placebo in patients with symptomatic seasonal allergic rhinitis. Additionally, reflective nasal symptom scores were significantly lower in bilastine than placebo recipients in patients with a history of seasonal allergic rhinitis who were challenged with grass pollen allergen in a single-centre, phase II study. Neither bilastine nor cetirizine was effective in the treatment of perennial allergic rhinitis with regard to the mean AUEC for reflective TSS in another well designed phase III trial. However, results may have been altered by differences in some baseline characteristics and placebo responses between study countries. In another well designed phase III trial, compared with placebo, bilastine was associated with a significantly greater change from baseline to day 28 in the mean reflective daily urticaria symptom score in patients with chronic urticaria. There were no significant differences in primary endpoint results between bilastine and any of the active comparators used in these trials (i.e. cetirizine, levocetirizine and desloratadine). Bilastine was generally well tolerated, with a tolerability profile that was generally similar to that of the other second-generation antihistamines included in phase III clinical trials.

Cross-contamination of foods and implications for food allergic patients.

PubMed

Taylor, Steve L; Baumert, Joseph L

2010-07-01

Cross-contamination presents a risk of unknown magnitude for food allergic consumers. Published cases likely represent the tip of a rather large iceberg. Cross-contamination can occur in homes, restaurants, food manufacturing plants, and on farms. The frequency of cross-contamination as the cause of accidental exposures to allergenic foods is unknown. Food allergic individuals can react to ingestion of trace levels of the offending food, although a highly variable range of threshold doses exist among populations of food allergic individuals. The magnitude of the risk posed to food allergic consumers by cross-contamination is characterized by the frequency of exposure to cross-contaminated foods, the dose of exposure, and the individual's threshold dose. The food and food service industry (and food preparers in homes as well) have the responsibility to provide and prepare foods that are safe for food allergic consumers, but quality of life may be improved with the recognition that safe (though very low) thresholds do exist.

The International Study of Asthma and Allergies in Childhood (ISAAC) has reported the prevalence of asthma and allergic diseases in many countries. We used the ISAAC core written questionnaire to examine the prevalence of asthma and allergic diseases in 6- to 14-year old schoolchildren in Tokyo. In 2005, we conducted a cross-sectional survey of all schoolchildren in all public schools located in the Setagaya area of Tokyo. Data were collected from 27,196 children in 95 schools. Prevalence ranged from 10.5% to 18.2% for asthma symptoms and from 10.9% to 19.6% for atopic dermatitis, with both conditions tending to decrease with age. As has been previously reported for all age groups, significantly higher rates of current asthma are observed in boys than in girls. The prevalence of allergic rhinoconjunctivitis exhibited a different pattern from that of asthma and atopic dermatitis, peaking at the age of 10 (34.8%). Prevalence of allergic rhinoconjunctivitis was 1.5 to 2-fold higher than the previous ISAAC studies that were performed in Tochigi and Fukuoka. In all age groups, symptoms of allergic conjunctivitis were more frequent from February to May, which coincides with the Japanese cedar pollen season, and were less frequent between June to September. The prevalence of asthma and atopic dermatitis was higher in younger schoolchildren. Tokyo schoolchildren appear to have extremely high prevalence rates of seasonal allergic rhinoconjunctivitis.

Allergic rhinitis is considered to be a major health problem that impairs quality of life. A possible relationship with psychological stress may exist. The aim of this study is to verify the relationship between persistent allergic rhinitis (PAR) and psychological stress aiming to improve treatment and thereby quality of life (QOL) of patients. Patients with PAR (166) were diagnosed then analyzed using the Kessler Psychological Distress Scale. Patients with allergic rhinitis and who were positive on the Kessler scale (122) were randomly divided equally into a control group which received levocetirizine and a study group which received levocetirizine and imipramine. Nasal symptom assessment and QOL assessment were performed in all patients after treatment. Of the 166 patients with PAR, 122 (73.5 %) were positive on the Kessler Psychological Distress Scale. There was a marked improvement in the study group compared with the control group as regards nasal symptoms with better QOL in the study group (6.93) compared with the control group (2.13). Psychological stress has a strong impact on persistent allergic rhinitis. When stress is controlled by a combined treatment of imipramine and levocetirizine, allergic rhinitis symptoms improved and a better QOL was obtained. 3b.

IgE is the antibody isotype found at the lowest concentration in the circulation. However IgE can undeniably play an important role in mediating allergic reactions; best exemplified by the clinical benefits of anti-IgE monoclonal antibody (omalizumab) therapy for some allergic diseases. This review will describe our current understanding of the interactions between IgE and its main receptors FcεRI and CD23 (FcεRII). We will review the known and potential functions of IgE in health and disease: in particular, its detrimental roles in allergic diseases and chronic spontaneous urticaria, and its protective functions in host defense against parasites and venoms. Finally, we will present an overview of the drugs that are in clinical development or have therapeutic potential for IgE-mediated allergic diseases. Copyright © 2018. Published by Elsevier Inc.

Disturbed sleep: linking allergic rhinitis, mood and suicidal behavior.

PubMed

Fang, Beverly J; Tonelli, Leonardo H; Soriano, Joseph J; Postolache, Teodor T

2010-01-01

Allergic inflammation is associated with mood disorders, exacerbation of depression, and suicidal behavior. Mediators of inflammation modulate sleep , with Th1 cytokines promoting NREM sleep and increasing sleepiness and Th2 cytokines (produced during allergic inflammation) impairing sleep. As sleep impairment is a rapidly modifiable suicide risk factor strongly associated with mood disorders, we review the literature leading to the hypothesis that allergic rhinitis leads to mood and anxiety disorders and an increased risk of suicide via sleep impairment. Specifically, allergic rhinitis can impair sleep through mechanical (obstructive) and molecular (cytokine production) processes. The high prevalence of mood and anxiety disorders and allergy, the nonabating suicide incidence, the currently available treatment modalities to treat sleep impairment and the need for novel therapeutic targets for mood and anxiety disorders, justify multilevel efforts to explore disturbance of sleep as a pathophysiological link.

Granulomatous lung diseases are a heterogeneous group of disorders that have a wide spectrum of pathologies with variable clinical manifestations and outcomes. Precise clinical evaluation, laboratory testing, pulmonary function testing, radiological imaging including high-resolution computed tomography and often histopathological assessment contribute to make a confident diagnosis of granulomatous lung diseases. Differential diagnosis is challenging, and includes both infectious (mycobacteria and fungi) and noninfectious lung diseases (sarcoidosis, necrotising sarcoid granulomatosis, hypersensitivity pneumonitis, hot tub lung, berylliosis, granulomatosis with polyangiitis, eosinophilic granulomatosis with polyangiitis, rheumatoid nodules, talc granulomatosis, Langerhans cell histiocytosis and bronchocentric granulomatosis). Bronchoalveolar lavage, endobronchial ultrasound-guided transbronchial needle aspiration, transbronchial cryobiopsy, positron emission tomography and genetic evaluation are potential candidates to improve the diagnostic accuracy for granulomatous lung diseases. As granuloma alone is a nonspecific histopathological finding, the multidisciplinary approach is important for a confident diagnosis. Copyright ©ERS 2017.

The level of specific class E immunoglobulins (IgE) in tear fluid is a useful diagnostic indicator for allergic conjunctivitis, but it is still unclear whether the measurement of tear fluid IgE is helpful for assessing the severity of allergic conjunctivitis. In this study, we evaluated the relation between tear fluid levels of specific IgE and features of allergic conjunctivitis. A prospective, nonrandomized, cross-sectional study was conducted in patients with allergic conjunctivitis (n = 55, allergic group) and age- and sex-matched healthy control subjects (n = 50, control group). Levels of specific IgE for cedar pollen, cat epithelium/dander and Dermatophagoides pteronyssinus were measured in tear fluid with the Immfast Check J1®. A severity score (0, 1, 2 or 3) was assigned for various changes of the palpebral and bulbar conjunctiva, as well as for limbal and corneal lesions. The levels of specific IgE for both cedar pollen, and D. pteronyssinus were significantly higher in the allergic group compared with the control group (p < 0.0001), while the level of specific IgE for cat epithelium/dander showed no significant difference between the two groups (p = 0.0777). When IgE levels were divided into four classes, the classes for both D. Pteronyssinus and cat epithelium/dander IgE were correlated with four features of allergic conjunctivitis. On the other hand, no correlation was found between the class of cedar pollen IgE and any of the features of allergic conjunctivitis. This study demonstrated that measurement of specific IgE in tear fluid may be useful for determining the severity of allergic conjunctivitis induced by indoor allergens. Although measurement of IgE in tear fluid is only a supplemental tool for evaluating the clinical activity of allergic conjunctivitis, the test can be useful for detecting specific IgE antibodies responsible for this condition.

Changes in the microbial populations on the skin of animals have traditionally been evaluated using conventional microbiology techniques. The sequencing of bacterial 16S rRNA genes has revealed that the human skin is inhabited by a highly diverse and variable microbiome that had previously not been demonstrated by culture-based methods. The goals of this study were to describe the microbiome inhabiting different areas of the canine skin, and to compare the skin microbiome of healthy and allergic dogs. DNA extracted from superficial skin swabs from healthy (n = 12) and allergic dogs (n = 6) from different regions of haired skin and mucosal surfaces were used for 454-pyrosequencing of the 16S rRNA gene. Principal coordinates analysis revealed clustering for the different skin sites across all dogs, with some mucosal sites and the perianal regions clustering separately from the haired skin sites. The rarefaction analysis revealed high individual variability between samples collected from healthy dogs and between the different skin sites. Higher species richness and microbial diversity were observed in the samples from haired skin when compared to mucosal surfaces or mucocutaneous junctions. In all examined regions, the most abundant phylum and family identified in the different regions of skin and mucosal surfaces were Proteobacteria and Oxalobacteriaceae. The skin of allergic dogs had lower species richness when compared to the healthy dogs. The allergic dogs had lower proportions of the Betaproteobacteria Ralstonia spp. when compared to the healthy dogs. The study demonstrates that the skin of dogs is inhabited by much more rich and diverse microbial communities than previously thought using culture-based methods. Our sequence data reveal high individual variability between samples collected from different patients. Differences in species richness was also seen between healthy and allergic dogs, with allergic dogs having lower species richness when compared

Genetically modified (GM) foods are evaluated carefully for their ability to induce allergic disease. However, few studies have tested the capacity of a GM food to act as an adjuvant, i.e. influencing allergic responses to other unrelated allergens at acute onset and in individuals with pre-existing allergy. We sought to evaluate the effect of short-term feeding of GM Bacillus thuringiensis (Bt)-maize (MON810) on the initiation and relapse of allergic asthma in mice. BALB/c mice were provided a diet containing 33% GM or non-GM maize for up to 34 days either before ovalbumin (OVA)-induced experimental allergic asthma or disease relapse in mice with pre-existing allergy. We observed that GM-maize feeding did not affect OVA-induced eosinophilic airway and lung inflammation, mucus hypersecretion or OVA-specific antibody production at initiation or relapse of allergic asthma. There was no adjuvant effect upon GM-maize consumption on the onset or severity of allergic responses in a mouse model of allergic asthma. PMID:25084284

Quercetin is the great representative of polyphenols, flavonoids subgroup, flavonols. Its main natural sources in foods are vegetables such as onions, the most studied quercetin containing foods, and broccoli; fruits (apples, berry crops, and grapes); some herbs; tea; and wine. Quercetin is known for its antioxidant activity in radical scavenging and anti-allergic properties characterized by stimulation of immune system, antiviral activity, inhibition of histamine release, decrease in pro-inflammatory cytokines, leukotrienes creation, and suppresses interleukin IL-4 production. It can improve the Th1/Th2 balance, and restrain antigen-specific IgE antibody formation. It is also effective in the inhibition of enzymes such as lipoxygenase, eosinophil and peroxidase and the suppression of inflammatory mediators. All mentioned mechanisms of action contribute to the anti-inflammatory and immunomodulating properties of quercetin that can be effectively utilized in treatment of late-phase, and late-late-phase bronchial asthma responses, allergic rhinitis and restricted peanut-induced anaphylactic reactions. Plant extract of quercetin is the main ingredient of many potential anti-allergic drugs, supplements and enriched products, which is more competent in inhibiting of IL-8 than cromolyn (anti-allergic drug disodium cromoglycate) and suppresses IL-6 and cytosolic calcium level increase.

Etiologic Aspect of Sarcoidosis as an Allergic Endogenous Infection Caused by Propionibacterium acnes

PubMed Central

2013-01-01

Sarcoidosis is a systemic granulomatous disease of unknown etiology. Propionibacterium acnes is the only microorganism that has been isolated from sarcoid lesions. Many P. acnes have been detected in sarcoid lymph nodes using quantitative PCR and in sarcoid granulomas by in situ hybridization. P. acnes trigger factor protein causes a cellular immune response only in sarcoid patients and induces pulmonary granulomas in mice sensitized with the protein and adjuvant, but only those with latent P. acnes infection in their lungs. Eradication of P. acnes by antibiotics prevents the development of granulomas in this experimental model. Although P. acnes is the most common commensal bacterium in the lungs and lymph nodes, P. acnes-specific antibody detected the bacterium within sarcoid granulomas of these organs. P. acnes can cause latent infection in the lung and lymph node and persist in a cell-wall-deficient form. The dormant form is activated endogenously under certain conditions and proliferates at the site of latent infection. In patients with P. acnes hypersensitivity, granulomatous inflammation is triggered by intracellular proliferation of the bacterium. Proliferating bacteria may escape granulomatous isolation, spreading to other organs. Latent P. acnes infection in systemic organs can be reactivated by another triggering event, leading to systemic sarcoidosis. PMID:23844371

Allergic conjunctivitis: a comprehensive review of the literature

2013-01-01

Ocular allergy represents one of the most common conditions encountered by allergists and ophthalmologists. Allergic conjunctivitis is often underdiagnosed and consequently undertreated. Basic and clinical research has provided a better understanding of the cells, mediators, and immunologic events, which occur in ocular allergy. New pharmacological agents have improved the efficacy and safety of ocular allergy treatment. An understanding of the immunologic mechanisms, clinical features, differential diagnosis, and treatment of ocular allergy may be useful to all specialists who deal with these patients. The purpose of this review is to systematically review literature underlining all the forms classified as ocular allergy: seasonal allergic conjunctivitis, perennial allergic conjunctivitis, vernal keratoconjunctivitis, atopic keratocongiuntivitis, contact allergy, and giant papillary conjunctivitis.

Low-grade inflammation conditions, e.g., type 2 diabetes, have been shown to be associated with an increased risk of rheumatoid arthritis (RA). However, the association between other chronic inflammatory conditions, e.g., asthma, allergic rhinitis, and atopic dermatitis, is still unclear. To investigate the risk of RA in patients with allergic diseases, including asthma, allergic rhinitis, and atopic dermatitis, by using a nationwide health claims database. The Taiwan National Health Insurance Research Database was used to assemble a cohort of 170,570 patients ages 20 years old and older diagnosed with allergic diseases, including asthma, allergic rhinitis, or atopic dermatitis. A comparison cohort of 170,238 patients was constructed from the same data base, with frequency matching for sex, 10-year age group, and year of insurance enrollment. Cox proportional hazards regression analyses were conducted to assess the association between the allergic diseases and incident RA. Asthma (adjusted hazard ratio [AHR] 1.67, [95% confidence interval {CI}], 1.32-2.62) and allergic rhinitis (AHR 1.62 [95% CI, 1.33-1.98]) were significantly associated with the incident RA. These associations remained significant even after excluding patients who had concurrent diagnoses of asthma and allergic rhinitis. Patients with more than one allergic disease had an increased risk of developing RA (AHR 1.98 [95% CI, 1.50-2.62]). Subgroup analysis further indicated that middle-aged and elderly female patients with more than one allergic disease exhibited a high risk of developing RA. Significant associations between common allergic diseases and incident RA was found in this population-based cohort study. Our findings provided support to the hypothesis that allergic diseases and RA might share a similar underlying etiologic pathway related to chronic inflammatory responses.

Histamine is an important mediator in the pathogenesis of asthma. Variation in genes along the histamine production, response, and degradation pathway may be important in predicting response to antihistamines. We hypothesize that differences exist among single-nucleotide polymorphisms (SNPs) in genes of the histamine pathway between children with allergic versus nonallergic asthma. Children (7–18 yr of age; n = 202) with asthma were classified as allergic or nonallergic based on allergy skin testing. Genotyping was performed to detect known SNPs (n = 10) among genes (HDC, HNMT, ABP1, HRH1, and HRH4) within the histamine pathway. Chi square tests and Cochran-Armitage Trend were used to identify associations between genetic variants and allergic or nonallergic asthma. Significance was determined by P < 0.05 and false-positive report probability. After correction for race differences in genotype were observed, HRH1-17 TT (6% allergic versus 0% nonallergic; P = 0.04), HNMT-464 TT (41% allergic versus 29% nonallergic; P = 0.04), and HNMT-1639 TT (30% allergic versus 20% nonallergic; P = 0.04) were overrepresented among children with allergic asthma. Genotype differences specifically among the African-American children were also observed: HRH1-17 TT (13% allergic versus 0% nonallergic; P = 0.04) and HNMT-1639 TT (23% allergic versus 3% nonallergic; P = 0.03) genotypes were overrepresented among African-American children with allergic asthma. Our study suggests that genetic variation within the histamine pathway may be associated with an allergic versus nonallergic asthma phenotype. Further studies are needed to determine the functional significance of identified SNPs and their impact on antihistamine response in patients with asthma and allergic disease. PMID:25909280

We evaluated the profiles of allergic rhino-conjunctivitis and asthma patients annually in Antalya, a Mediterranean coastal city in Turkey. We evaluated patients' allergic clinical status, and recorded the climate and pollens in the city center air, investigating any correlation between pollination, climatic conditions and allergic disorders. The meteorological conditions and the pollen count/cm2 during every month of the year and the concordance of this with the patient's clinical status were evaluated. SPT positivity for plantago lanceolata, aspergillus fumigatus and d. pteronyssinus was significant in patients younger than 40 years old. Pollination levels are consistent from March 2010 to February 2011. In Antalya, high levels occur mostly from April to June, thus we performed skin prick tests mostly in May/June (~30%). During these months meteorological conditions of the city were windy with low humidity, without rain, and lukewarm temperatures, all of which contribute to high-risk conditions for seasonal allergies. The major allergen between April and June was derived from Graminea; between February and March was Cupressus spp; and between March and June was Pinus spp. These results suggest that the pollination is correlated with allergic conditions and thus SPT might be best performed according to the pollen count.

Immunotherapy of allergic contact dermatitis.

PubMed

Spiewak, Radoslaw

2011-08-01

The term 'immunotherapy' refers to treating diseases by inducing, enhancing or suppressing immune responses. As allergy is an excessive, detrimental immune reaction to otherwise harmless environmental substances, immunotherapy of allergic disease is aimed at the induction of tolerance toward sensitizing antigens. This article focuses on the historical developments, present state and future outlook for immunotherapy with haptens as a therapeutic modality for allergic contact dermatitis. Inspired by the effectiveness of immunotherapy in respiratory allergies, attempts were undertaken at curing allergic contact dermatitis by means of controlled administration of the sensitizing haptens. Animal and human experiments confirmed that tolerance to haptens can be induced most effectively when the induction of tolerance precedes attempted sensitization. In real life, however, therapy is sought by people who are already sensitized and an effective reversal of hypersensitivity seems more difficult to achieve. Decades of research on Rhus hypersensitivity led to a conclusion that immunotherapy can suppress Rhus dermatitis, however, only to a limited degree, for a short period of time, and at a high risk of side effects, which makes this method therapeutically unprofitable. Methodological problems with most available studies of immunotherapy of contact allergy to nickel make any definite conclusions impossible at this stage.

Aspergillus myofasciitis is a rare infection of the muscles and their fascial sheaths that has been reported in patients with immune deficiencies of various kinds but, until now, not with chronic granulomatous disease (CGD). Patients affected by CGD are at high risk of invasive aspergillus infections. The case described involves a 14-year-old boy with a severe autosomal recessive CGD who was admitted to hospital with an Aspergillus myofasciitis of the left forearm. He was treated with liposomal amphotericin for 14 days and then with oral voriconazole for three months with an excellent clinical outcome. He did not evidence any recurrence in the following 30 months using itraconazole prophylaxis.

Objective: To observe the clinical characteristics of allergic conjunctivitis, and the correlations with skin prick test results. Methods: A retrospective study. Forty patients with positive skin prick test result were included. Patients underwent an ophthalmologic examination to identify their primary presenting signs and symptoms. The allergy types were divided into 5 groups. All dates were analyzed for the dependence, normality and homogeneity of variance. Chi-square test, Mann-Whitney U test, Kruskal-Wallis H test and Spearman correlation analysis were performed accordingly. Results: Among 40 patients, 18(45.0%) had a clinical diagnosis of seasonal allergic conjunctivitis, 14(35.0%) had perennial allergic conjunctivitis, 5(12.5%) had vernal keratoconjunctivitis, and 2(5.0%) had atopic keratoconjunctivits, and 1(2.5%) had giant papillary conjunctivitis. There was no significant difference in the number of symptoms and signs score among different types of allergic conjunctivitis, the score of itching and hyperemia had a positive relationship with the number of positive allergens ( r =0.74, P< 0.05. r =0.96, P< 0.05). The primary symptoms and signs are itching and hyperemia; dust and pollens are the most common allergens. The more positive result of the test of the allergen, the more symptoms and signs encountered in terms of severity. Conclusion: Seasonal allergic conjunctivitis was the most prevalent disorder, the most important clinical characteristics of allergic conjunctivitis are itching and conjunctival congestion, the main allergens are dust and pollens, patients may be sensitive to multiple allergens.

Respiratory infections cause high morbidity and mortality worldwide. This study aims to estimate the relationship between allergic respiratory diseases with the occurrence of recurrent respiratory infection (RRI) in children and adolescents. The International Study of Asthma and Allergies in Childhood questionnaire and a questionnaire that provides data on the history of respiratory infections and the use of antibiotics were used to obtain data from patients. The relationship between the presence of asthma or allergic rhinitis and the occurrence of respiratory infections in childhood was analyzed. We interviewed the caregivers of 531 children aged 0 to 15 years. The average age of participants was 7.43 years, with females accounting for 52.2%. This study found significant relationship between: presence of asthma or allergic rhinitis with RRI, with prevalence ratio (PR) of 2.47 (1.51-4.02) and 1.61 (1.34-1.93), respectively; respiratory allergies with use of antibiotics for respiratory problems, with PR of 5.32 (2.17-13.0) for asthma and of 1.64 (1.29-2.09) for allergic rhinitis; asthma and allergic rhinitis with diseases of the lower respiratory airways, with PR of 7.82 (4.63-13.21) and 1.65 (1.38-1.96), respectively. In contrast, no relationship between upper respiratory airway diseases and asthma and allergic rhinitis was observed, with PR of 0.71 (0.35-1.48) and 1.30 (0.87-1.95), respectively. RRI is associated with previous atopic diseases, and these conditions should be considered when treating children.

Effects of Isoprene- and Toluene-Generated Smog on Allergic ...

EPA Pesticide Factsheets

Reactions of organic compounds with nitric oxide (NO) and sunlight produce complex mixtures of pollutants including secondary organic aerosol (SOA), ozone (O3), nitrogen dioxide (NO2), and reactive aldehydes. The health effects of these photochemical smog mixtures in susceptible populations including asthmatics are unclear. We assessed effects of smog generated from mixtures of NO with isoprene (IS) or toluene (TL) on allergic inflammatory responses in Balb/cJ mice. House dust mite (HDM)-sensitized or control mice were all challenged with HDM intranasally 1 d prior to whole-body inhalation exposure to IS (chamber average 509 ppb NO2, 246 ppb O3, and 160 g/m3 SOA), TL (217 ppb NO2, 129 ppb O3, and 376 g/m3 SOA), or HEPA-filtered air (4 h/d for 2 days). Mice were necropsied within 3 h after the second exposure (2 d post-HDM challenge). Assessment of breathing parameters during exposure with double-chamber plethysmography showed a trend for increased specific airway resistance and decreased minute volume during the second day of TL exposure in both non-allergic and HDM-allergic mice. HDM-allergic air-exposed mice had significant increases in numbers of bronchoalveolar lavage (BAL) alveolar macrophages (AM) and eosinophils (EO), and trends for increases in BAL indices of lung injury in comparison with non-allergic air-exposed mice. Exposure to either IS or TL attenuated the increases in AM, EO, and lung injury markers in HDM-allergic mice. The results of this

Adenoid hypertrophy (AH) may cause several comorbid conditions including sleep apnea, chronic serous otitis and sinusitis. Such conditions are more common among children with allergic diseases. In our study, we aimed to determine the patient profile associated with higher incidence of adenoid hypertrophy and the related influential factors. The study included 1322 children being treated and followed up for allergic conditions. 100 children with no allergic diseases presenting during the same period to the clinic were included as the control group. Skin prick test for the same allergens was performed for all patients. Adenoid tissue was analyzed by an ENT specialist and the diagnosis was confirmed based on the patient history, endoscopic physical examination and radiology. Of the patients, 765 (57.9%) were males and 557 (42.1%) were females and their mean age was 5.9±3.3 years. In the control group, 56 (56%) children were males and 44 (44%) were females and their mean age was 6.3±4.1 years. Children with allergic disease and control subjects did not differ significantly by age and gender. Adenoid hypertrophy was identified in 164 (12.4%) of the patients with allergic disease and in 3 (3%) of the controls. Allergic children were divided into two groups, as children with and without AH, respectively. The groups did not differ statistically significantly by gender, age or familial history of atopic disease. However, cigarette smoke exposure at home and presence of allergic rhinitis was significantly more frequent in the group of patients with AH. In the logistic model investigating the effect of variables on AH presence (according to age, gender, cigarette smoke exposure, asthma, AR, AD presence, atopy presence, sensitivity to house dust, pollen, epithelium, Alternaria alternata and cockroach), AR presence and cigarette smoke exposure were statistically significant. AH frequency is higher in children with allergic disease compared to controls. The most common

Allergic rhinitis is a common inflammatory nasal mucosal disease characterized by sneezing, watery nasal discharge, nasal obstruction and itching. Although allergen-specific antibodies play a main role in the allergic airway inflammation, neuronal inflammation may also contribute to the symptoms of allergic rhinitis. Neuronal inflammation is primarily caused by the stimulation of sensory nerve endings with histamine. It has been shown that neurotrophins may also have a role in allergic reactions and neuronal inflammation. Nerve growth factor, neurotrophin 3 (NT-3), neurotrophin 4/5 and brain-derived neurotrophic factor are members of the neurotrophin family. Although nerve growth factor and brain-derived neurotrophic factor are well studied in allergic rhinitis patients, the exact role of Neurotrophin-3 is not known. To investigate the possible roles of neurotrophin-3 in allergic rhinitis patients. Case-control study. Neurotrophin-3 levels were studied in the inferior turbinate and serum samples of 20 allergic rhinitis and 13 control patients. Neurotrophin-3 staining of nasal tissues was evaluated by immunohistochemistry and ELISA was used for the determination of serum Neurotrophin-3 levels. Neurotrophin-3 staining scores were statistically higher in the study group than in the control patients (p=0.001). Regarding serum Neurotrophin-3 levels, no statistically significant difference could be determined between allergic rhinitis and control patients (p=0.156). When comparing the serum NT-3 levels with tissue staining scores, there were no statistically significant differences in the allergic rhinitis and control groups (p=0.254 for allergic rhinitis and p=0.624 for control groups). We suggest that Neurotrophin-3 might affect the nasal mucosa locally without being released into the systemic circulation in allergic rhinitis patients.

Cyclooxgenase-2 (COX-2) knock-out mouse experiments showed that COX-2 was necessary for in vivo allergic inflammation, such as passive cutaneous anaphylaxis, passive systemic anaphylaxis, and triphasic cutaneous allergic reaction. TargetScan analysis predicted COX-2 as a target of miR-26a and miR-26b. miR-26a/-26b decreased luciferase activity associated with COX-2–3′-UTR. miR-26a/-26b exerted negative effects on the features of in vitro and in vivo allergic inflammation by targeting COX-2. ChIP assays showed the binding of HDAC3 and SNAIL, but not COX-2, to the promoter sequences of miR-26a and miR-26b. Cytokine array analysis showed that the induction of chemokines, such as MIP-2, in the mouse passive systemic anaphylaxis model occurred in a COX-2-dependent manner. ChIP assays showed the binding of HDAC3 and COX-2 to the promoter sequences of MIP-2. In vitro and in vivo allergic inflammation was accompanied by the increased expression of MIP-2. miR-26a/-26b negatively regulated the expression of MIP-2. Allergic inflammation enhanced the tumorigenic and metastatic potential of cancer cells and induced positive feedback involving cancer cells and stromal cells, such as mast cells, macrophages, and endothelial cells. miR-26a mimic and miR-26b mimic negatively regulated the positive feedback between cancer cells and stromal cells and the positive feedback among stromal cells. miR-26a/-26b negatively regulated the enhanced tumorigenic potential by allergic inflammation. COX-2 was necessary for the enhanced metastatic potential of cancer cells by allergic inflammation. Taken together, our results indicate that the miR26a/-26b-COX-2-MIP-2 loop regulates allergic inflammation and the feedback relationship between allergic inflammation and the enhanced tumorigenic and metastatic potential.

Common variable immunodeficiency (CVID) is typically characterized by hypogammaglobulinemia and often but not always recurrent infections. Paradoxically, 8-22% of patients with CVID develop granulomatous disease. Granulomata have been described in many organs including the lungs, skin, liver, spleen, kidneys, eyes, lymph nodes, and intestines. Data about central nervous system (CNS) involvement in CVID are extremely rare. We aim to describe a case series and include an extensive literature review of CNS involvement in CVID to understand the different features and patterns of the disease. We searched the English Pubmed database for relevant articles between 1950 and 2014 using the Key Words "common variable immunodeficiency", "granulomatous disease", "brain", "sarcoidosis", and "sarcoid-like syndrome". Data from all case series, surveys, systematic reviews, and individual case reports, as well as retrospective studies were extracted. A total of 15 patients were reported in the literature. We combined our experience with four additional patients from The Cleveland Clinic between 2009 and 2014. Demographics, clinical features, laboratory and imaging findings, treatment and follow-up were extracted for the 19 patients and summarized descriptively. Female sex and Caucasian race represented 63.2% (12/19), and 80% of the patients, respectively. The mean age of CVID diagnosis was 24 years; mean age when the CNS disease was diagnosed was 21.5 years. 68.4% of the patients (13/19) had granulomas involving ≥2 organs including the central nervous system, 31.6% (6/19) had CNS granulomas only. Associated granulomatous diseases occurred in lungs (72.7%), lymph nodes (27.2%), spleen (27.2%), eyes (18.1%), liver (18.1%), parotid glands (9%), and skin (9%). Fifty-three percent (10/19) of the patients had documented recurrent infections, all of them being upper respiratory tract infections. CNS manifestations included seizures (31.6%), headaches (21%), vision loss (15.7%), decreased

Mammary glands from cows with protothecal mastitis were examined by light and electron microscopy at 6, 13, 20, and greater than 180 days after infection. With increasing time, there were increases in severity of granulomatous inflammation, number of endospores and sporangia, and ratio of degenerate to intact algae. Algae were found in macrophages but were not seen in neutrophils, epithelial cells, or myoepithelial cells. Macrophages containing algae were markedly enlarged, chiefly from reduplication of the Golgi complex and its associated vesicles. Intracellular algae were degenerate and consisted of intact cell wall profiles which contained membrane fragments but lacked nuclei and cytoplasmic organelles. Degenerate algae in vitro had thin cell walls and did not undergo internal lysis. Cell wall material of intracellular algae stained as an acidic, nonsulfated, carboxylated glycoprotein. These findings suggest that intracellular Prototheca zopfii degenerate by progressive lysis of internal organelles with persistence of cell wall glycans and that development of aberrant cell wall forms occurs as a defective response by host macrophages.

Current Concepts of Hyperinflammation in Chronic Granulomatous Disease

Chronic granulomatous disease (CGD) is the most common inherited disorder of phagocytic functions, caused by genetic defects in the leukocyte nicotinamide dinucleotide phosphate (NADPH) oxidase. Consequently, CGD phagocytes are impaired in destroying phagocytosed microorganisms, rendering the patients susceptible to bacterial and fungal infections. Besides this immunodeficiency, CGD patients suffer from various autoinflammatory symptoms, such as granuloma formation in the skin or urinary tract and Crohn-like colitis. Owing to improved antimicrobial treatment strategies, the majority of CGD patients reaches adulthood, yet the autoinflammatory manifestations become more prominent by lack of causative treatment options. The underlying pathomechanisms driving hyperinflammatory reactions in CGD are poorly understood, but recent studies implicate reduced neutrophil apoptosis and efferocytosis, dysbalanced innate immune receptors, altered T-cell surface redox levels, induction of Th17 cells, the enzyme indolamine-2,3-dioxygenase (IDO), impaired Nrf2 activity, and inflammasome activation. Here we discuss immunological mechanisms of hyperinflammation and their potential therapeutic implications in CGD. PMID:21808651

Shoe allergic contact dermatitis.

2014-01-01

Foot dermatitis is a widespread condition, affecting men and women of all ages. Because of the location, this condition may present as a debilitating problem to those who have it. Allergic contact dermatitis involving the feet is frequently due to shoes or socks. The allergens that cause shoe dermatitis can be found in any constituent of footwear, including rubber, adhesives, leather, dyes, metals, and medicaments. The goal of treatment is to identify and minimize contact with the offending allergen(s). The lack of product information released from shoe manufacturers and the continually changing trends in footwear present a challenge in treating this condition. The aim of this study is to review the current literature on allergic contact shoe dermatitis; clinical presentation, allergens, patch testing, and management will be discussed. PubMed and MEDLINE databases were used for the search, with a focus on literature updates from the last 15 years.

To study the clinical and pathologic features of granulomatous lobular mastitis (GLM). Sixty-eight cases of GLM were retrieved from the archival file. The clinical data and histologic features were retrospectively reviewed. Sixty-eight patients presented with breast mass. Ulceration in overlying breast skin was seen in 9 cases. Most of the patients had history of breast feeding. None of them had evidence of specific infections involving the breast. The clinical and radiologic features mimicked malignancy. Histologically, GLM was characterized by the presence of non-necrotizing granulomas, usually admixed with neutrophils and associated with benign ductolobular units. The ductolobular architecture was still preserved. The duration of follow up ranged from 6 to 36 months. Four patients suffered from disease recurrence. GLM shows clinical and radiologic features reminiscent of breast cancer. Correct diagnosis requires histologic examination of the biopsy specimens.

In previous research, patients with seasonal allergic rhinitis (SAR) showed poorer school and work performance during periods of acute allergic inflammation, supporting the idea of an impact of SAR on cognitive functions. However, the specific cognitive domains particularly vulnerable to inflammatory processes are unclear. In this study, the influence of SAR on memory and multitasking performance, as two potentially vulnerable cognitive domains essential in everyday life functioning, was investigated in patients with SAR. Non-medicated patients with SAR (n = 41) and healthy non-allergic controls (n = 42) performed a dual-task paradigm and a verbal learning and memory test during and out of symptomatic allergy periods (pollen vs. non-pollen season). Disease-related factors (e.g. symptom severity, duration of symptoms, duration of disease) and allergy-related quality of life were evaluated as potential influences of cognitive performance. During the symptomatic allergy period, patients showed (1) poorer performance in word list-based learning (P = 0.028) and (2) a general slowing in processing speed (P < 0.001) and a shift in processing strategy (P < 0.001) in multitasking. Yet, typical parameters indicating specific multitasking costs were not affected. A significant negative association was found between learning performance and duration of disease (r = -0.451, P = 0.004), whereas symptom severity (r = 0.326; P = 0.037) and quality of life (r = 0.379; P = 0.015) were positively associated with multitasking strategy. Our findings suggest that SAR has a differentiated and complex impact on cognitive functions, which should be considered in the management of SAR symptoms. They also call attention to the importance of selecting sensitive measures and carefully interpreting cognitive outcomes. © 2017 John Wiley & Sons Ltd.

Background Many allergic conditions occur more frequently in African-American patients when compared with white patients; however it is not known whether this represents genetic predisposition or disparate environmental exposures. Objective To assess the relationship of self-reported race and genetic ancestry to allergic sensitization. Methods We included 601 women enrolled in a population-based cohort study whose self-reported race was African-American or white. Genetic ancestry was estimated using markers that differentiate West African and European ancestry. We assessed the relationship between allergic sensitization (defined as ≥1 allergen-specific IgE result) and both self-reported race and genetic ancestry. Regression models adjusted for socio-demographic variables, environmental exposures, and location of residence. Results The average proportion of West African ancestry in African-American participants was 0.69, whereas the mean proportion of European ancestry in white participants was 0.79. Self-reported African-American race was associated with allergic sensitization when compared with those who reported being white (adjusted odds ratio [aOR] 2.19; 95% confidence interval [CI] 1.22 – 3.93) even after adjusting for other variables. Genetic ancestry was not significantly associated with allergic sensitization after accounting for location of residence (aOR 2.09 for urban vs. suburban residence, 95% CI 1.32 −3.31). Conclusion Self-reported race and location of residence appeared to be more important predictors of allergic sensitization when compared with genetic ancestry, suggesting that the disparity in allergic sensitization by race may be primarily due to environmental factors rather than genetic differences. Clinical Implications These data suggest that efforts to eliminate disparities in allergic sensitization should focus on contributing environmental factors. PMID:19014772

[Allergic and non-allergic hypersensitivity to non-opioid analgesics, antipyretics and nonsteroidal anti-inflammatory drugs in children: epidemiology, clinical aspects, pathophysiology, diagnosis and prevention].

PubMed

Ponvert, C

2012-05-01

Non-opioid analgesics, antipyretics and nonsteroidal anti-inflammatory drugs are widely used, but suspected allergic reactions to these drugs are rare, especially in children. Most frequent reactions are cutaneous (urticaria, angioedema) and respiratory (rhinitis, asthma). Other reactions (anaphylaxis, potentially harmful toxidermias) are rare. In a few patients, reactions may result from a specific (allergic) hypersensitivity, with positive responses in prick and intradermal tests (anaphylaxis, immediate urticaria and/or angioedema) and in intradermal and patch tests (non-immediate reactions). However, most reactions result from a non-specific (non-allergic) hypersensitivity (intolerance), with a frequent cross-reactivity between the various families of analgesics, antipyretics and nonsteroidal anti-inflammatory drugs, including paracetamol. Based on a convincing clinical history and/or positive responses in challenge tests, intolerance to non-opioid analgesics, antipyretics and nonsteroidal anti-inflammatory drugs has been diagnosed in 13 to 50% of the patients with allergic-like reactions to these drugs. Risk factors are a personal atopy and age. Prevention is based on administration of other (families of) analgesics, antipyretics and nonsteroidal anti-inflammatory drugs in patients with allergic hypersensitivity to these drugs. In patients with non-allergic hypersensitivity, prevention is based on administration of drugs with a low cyclo-oxygenase-1 inhibitory activity (if tolerated). Desensitization is efficient in patients with respiratory reactions, but does not work in patients with mucocutaneous reactions and anaphylaxis. Copyright © 2012 Elsevier Masson SAS.

Bifidobacteria are beneficial bacteria for humans. These bacteria are particularly effective at protecting against infectious diseases and modulating the immune response. It was shown that in newborns, the fecal distribution of the colonizing Bifidobacterium species influences the prevalence of allergic diseases. This study aimed to compare the faecal Bifidobacterium species of allergic children to those of healthy children to detect species level differences in faecal distribution. Stool samples were obtained from 99 children between 0 and 3 years of age whose clinical symptoms and laboratory reports were compatible with atopic dermatitis and allergic asthma. Samples were also obtained from 102 healthy children who were similar to the case group with respect to age and sex. Bifidobacteria were isolated by culture and identified at the genus level by API 20 A. In addition, 7 unique species-specific primers were used for the molecular characterization of bifidobacteria. The McNemar test was used for statistical analyses, and p < 0.05 was accepted as significant. Bifidobacterium longum was detected in 11 (11.1%) of the allergic children and in 31 (30.3%) of the healthy children. Statistical analysis revealed a significant difference in the prevalence of B. longum between these two groups (X(2): 11.2, p < 0.001). However, no significant differences in the prevalence of other Bifidobacterium species were found between faecal samples from healthy and allergic children. (p > 0.05). The significant difference in the isolation of B. longum from our study groups suggests that this species favors the host by preventing the development of asthma and allergic dermatitis. Based on these results, we propose that the production of probiotics in accordance with country-specific Bifidobacterium species densities would improve public health. Thus, country-specific prospective case-control studies that collect broad data sets are needed. Copyright © 2014 Elsevier Ltd. All

Natural polyphenol has been widely believed to be effective in allergy remission. Currently, most of the natural polyphenol products come from terrestrial sources such as tea, grape seeds among others, and few polyphenols have been developed from algae for their anti-allergic activity. The aim of the study was to screen some commercial seaweed for natural extracts with anti-allergic activity. Five algae including Laminaria japonica, Porphyra sp., Spirulina platensis, Chlorella pyrenoidosa and Scytosiphon sp. were extracted with ethanol, and the extracts were evaluated for total polyphenol contents and anti-allergic activity with the hyaluronidase inhibition assay. Results showed that the total polyphenol contents in the ethanol extracts ranged from 1.67% to 8.47%, while the highest was found in the extract from Scytosiphon sp. Hyaluronidase inhibition assay showed that the extracts from Scytosiphon sp. had the lowest IC50, 0.67 mg mL-1, while Chlorella pyrenoidosa extract had the highest IC50, 15.07 mg mL-1. The anti-allergic activity of Scytosiphon sp. extract was even higher than the typical anti-allergic drug Disodium Cromoglycate (DSCG) (IC50 = 1.13 mg mL-1), and was similar with natural polyphenol from Epigallocatechin gallate (EGCG) (IC50 = 0.56 mg mL-1). These results indicated that the ethanol extract of Scytosiphon sp. contains a high concentration of polyphenol with high anti-allergic activity. Potentially Scytosiphon sp. can be developed to a natural anti-allergic compound for allergy remission.

Discovering susceptibility genes for allergic rhinitis and allergy using a genome-wide association study strategy.

Allergic rhinitis and allergy are complex conditions, in which both genetic and environmental factors contribute to the pathogenesis. Genome-wide association studies (GWASs) employing common single-nucleotide polymorphisms have accelerated the search for novel and interesting genes, and also confirmed the role of some previously described genes which may be involved in the cause of allergic rhinitis and allergy. The aim of this review is to provide an overview of the genetic basis of allergic rhinitis and the associated allergic phenotypes, with particular focus on GWASs. The last decade has been marked by the publication of more than 20 GWASs of allergic rhinitis and the associated allergic phenotypes. Allergic diseases and traits have been shown to share a large number of genetic susceptibility loci, of which IL33/IL1RL1, IL-13-RAD50 and C11orf30/LRRC32 appear to be important for more than two allergic phenotypes. GWASs have further reflected the genetic heterogeneity underlying allergic phenotypes. Large-scale genome-wide association strategies are underway to discover new susceptibility variants for allergic rhinitis and allergic phenotypes. Characterization of the underlying genetics provides us with an insight into the potential targets for future studies and the corresponding interventions.

Background Changes in the microbial populations on the skin of animals have traditionally been evaluated using conventional microbiology techniques. The sequencing of bacterial 16S rRNA genes has revealed that the human skin is inhabited by a highly diverse and variable microbiome that had previously not been demonstrated by culture-based methods. The goals of this study were to describe the microbiome inhabiting different areas of the canine skin, and to compare the skin microbiome of healthy and allergic dogs. Methodology/Principal Findings DNA extracted from superficial skin swabs from healthy (n = 12) and allergic dogs (n = 6) from different regions of haired skin and mucosal surfaces were used for 454-pyrosequencing of the 16S rRNA gene. Principal coordinates analysis revealed clustering for the different skin sites across all dogs, with some mucosal sites and the perianal regions clustering separately from the haired skin sites. The rarefaction analysis revealed high individual variability between samples collected from healthy dogs and between the different skin sites. Higher species richness and microbial diversity were observed in the samples from haired skin when compared to mucosal surfaces or mucocutaneous junctions. In all examined regions, the most abundant phylum and family identified in the different regions of skin and mucosal surfaces were Proteobacteria and Oxalobacteriaceae. The skin of allergic dogs had lower species richness when compared to the healthy dogs. The allergic dogs had lower proportions of the Betaproteobacteria Ralstonia spp. when compared to the healthy dogs. Conclusions/Significance The study demonstrates that the skin of dogs is inhabited by much more rich and diverse microbial communities than previously thought using culture-based methods. Our sequence data reveal high individual variability between samples collected from different patients. Differences in species richness was also seen between healthy and allergic

Allergic conjunctivitis (AC) is a very common disease, especially in association with allergic rhinitis but may also occur in isolated presentation. The treatment of AC has long been based on antihistamines, cromones and topical corticosteroids, but none of these drugs completely abolishes the clinical expression of AC. The development of new drugs for AC is analyzed highlighting the recent insights into the pathophysiological mechanisms of the disease. The major aim of development of drugs for AC is to have agents able to prevent the inflammatory effects of the interaction between the allergen and the specific IgE antibodies on mast cell surface. This may be obtained by blocking the effects of histamine (the main mediator of early allergic response) by H1-receptor antagonists, inhibiting the release of soluble factors able to recruit inflammatory cells (that sustain prolonged inflammation) by mast-cell stabilizers, inhibiting the effects of single mediators, inducing tolerance to the allergen by specific immunotherapy or even acting on factors related to activation and differentiation of T lymphocytes such as the toll-like receptors. AC is an underestimated disease for which there is a search of more effective treatments. The availability of the drugs under current evaluation will allow more refined therapeutic strategies to apply according to the characteristics and the clinical severity of AC.

Primary granulomatous angiitis of the central nervous system (CNS) is extremely rare. Its preoperative diagnosis is difficult as the condition displays nonspecific features on routine neuroimaging investigations. In this paper, the authors report findings of magnetic resonance (MR) spectroscopy and fractional anisotropy (FA) with diffusion tensor MR imaging in a case of granulomatous angiitis of the CNS. A 30-year-old man presented with morning headaches and grand mal seizures. An MR image revealed a mass resembling glioblastoma in the right temporal lobe. Magnetic resonance spectroscopy showed a high choline/creatine (Cho/Cr) ratio indicative of a malignant neoplasm, accompanied by a slight elevation of glutamate and glutamine. The FA value was very low, which is inconsistent with malignant glioma. The mass was totally removed surgically. Histologically, the peripheral lesion of the mass consisted of a rough accumulation of fat granule cells, infiltration of inflammatory cells, and distribution of capillary vessels. Some vessels within the lesion were replaced by granulomas. The histological diagnosis was granulomatous angiitis of the CNS. The MIB-1-positive rate of the granuloma was approximately 5%. Both MR spectroscopy and FA were unable to accurately diagnose granulomatous angiitis of the CNS prior to surgery; however, elevated Cho/Cr and glutamate and glutamine shown by MR spectroscopy may indicate the moderate proliferation potential of the granuloma and the inflammatory process, respectively, in this condition. Although the low FA value in the present case enabled the authors to rule out a diagnosis of glioblastoma, FA values in inflammatory lesions require careful interpretation.

Bata-lactam antibiotics are the most commonly used antibiotics which usually cause serious IgE-mediated allergic reactions. Of all bata-lactam antibiotics, penicillins have so far been the best-studied, but the studies of cephalosporins and their cross-reactivity with penicillins are rare. We sought to evaluate the IgE response in vitro and estimate cross-reactivity between penicillins and cephalosporins in patients allergic to penicillins. We studied 87 control subjects and 420 subjects allergic to penicillins. Radioallergosorbent test (RAST) was performed to detect eight types of specific-penicillin IgE and eleven types of specific-cephalosporin IgE. The cross-reactivity and different molecules recognition by IgE were studied with a radioallergosorbent inhibition test. Of 420 patients allergic to penicillins, 95 patients (22.62%) showed specific-cephalosporin IgE positive, 73 patients (17.38%) showed IgEs positive to both penicillins and cephalosporins. In specific-penicillin IgE positive group, the positive rate of specific-cephalosporin IgE was significantly higher than in specific-penicillin IgE negative group (27.14% vs. 14.57%, p < 0.01). In urticaria group, the positive rate of specific-cephalosporin IgE was significantly higher than in other symptoms group (30.65% vs. 8.11%, p < 0.05). The analysis of drugs which have the same or similar side-chains showed that benzylpenicillanyl-IgE (BPA-IgE), ampicillanyl-IgE (APA-IgE), amoxicillanyl-IgE (AXA-IgE) were respectively related to cephalothanyl-IgE (CLA-IgE), cephalexanyl-IgE (CEXA-IgE), cephalexanyl-IgE (CEXA-IgE)in sera of penicillin-allergic patients we studied, and compared with patients who had negative amoxicillin-IgE, the positive rates of specific-ampicillin IgE and specific-cephalexin IgE were significantly higher in patients who had positive amoxicillin-IgE (14.43% vs. 3.72%, 14.00% vs. 2.96%, p < 0.01). Radioallergosorbent test and radioallergosorbent inhibition test confirmed that both nuclear

Clinical patterns in pediatric patients with dry eye syndrome and allergic conjunctivitis were investigated. Children aged 6 to 15 years with dry eye symptoms were included. Slit-lamp examinations including tear film break-up time, Schirmer's test, and fluorescent staining were performed, and subjective symptoms were investigated. Patients with allergic conjunctivitis were subjected to skin prick tests. Tear film break-up time was shorter and the number of symptoms related to dry eyes was higher in pediatric patients with allergic conjunctivitis than in those without allergic conjunctivitis. Patients with allergic conjunctivitis who had higher numbers of positive allergens on the skin prick test also had shorter tear film break-up time. Because pediatric patients with dry eye syndrome tend to complain less about their symptoms than adult patients, dry eye syndrome is commonly overlooked. This study showed that dry eyes tended to be more severe with the presence of allergic conjunctivitis; the more allergens present, the more severe the dry eyes. More attention should be paid to the treatment of pediatric patients with dry eyes accompanied by allergies. Copyright 2013, SLACK Incorporated.

The incidence of asthma and allergic rhinitis (AR) is significantly increased, especially in younger children. Current treatment for children with asthma and allergic rhinitis include allergen avoidance, standard pharmacotherapy, and immunotherapy. Since standard pharmacotherapy is prescribed for symptoms, immunotherapy at present plays an important role in the treatment of allergic diseases. This article presents insights into the up-to-date understanding of immunotherapy in the treatment of children with allergic rhinitis and asthma. PubMed articles published from 1990 to 2014 were reviewed using the MeSH terms "asthma", "allergic rhinitis", "children", and "immune therapy". Additional articles were identified by hand searching of the references in the initial search. Numerous studies have shown that sublingual application of allergen specific immunotherapy (SLIT) is an adequate, safe and efficient substitution to subcutaneous route of allergens administration (SCIT) in the treatment of IgE-mediated respiratory tract allergies in children. According to the literature, better clinical efficacy is connected with the duration of treatment and mono sensitized patients. At least 3 years of treatment and stable asthma before the immunotherapy are positive predictors of good clinical efficacy and tolerability of SLIT. SLIT reduces the symptoms of allergic diseases and the use of medicaments, and improves the quality of life of children with the diseases.

Choi, Yun Ho; Jin, Guang Yu; Guo, Hui Shu

Highlights: Black-Right-Pointing-Pointer Silibinin diminishes ovalbumin-induced inflammatory reactions in the mouse lung. Black-Right-Pointing-Pointer Silibinin reduces the levels of various cytokines into the lung of allergic mice. Black-Right-Pointing-Pointer Silibinin prevents the development of airway hyperresponsiveness in allergic mice. Black-Right-Pointing-Pointer Silibinin suppresses NF-{kappa}B transcriptional activity. -- Abstract: Allergic asthma is a chronic inflammatory disease regulated by coordination of T-helper2 (Th2) type cytokines and inflammatory signal molecules. Silibinin is one of the main flavonoids produced by milk thistle, which is reported to inhibit the inflammatory response by suppressing the nuclear factor-kappa B (NF-{kappa}B) pathway. Because NF-{kappa}B activation plays a pivotal role in the pathogenesismore » of allergic inflammation, we have investigated the effect of silibinin on a mouse ovalbumin (OVA)-induced asthma model. Airway hyperresponsiveness, cytokines levels, and eosinophilic infiltration were analyzed in bronchoalveolar lavage fluid and lung tissue. Pretreatment of silibinin significantly inhibited airway inflammatory cell recruitment and peribronchiolar inflammation and reduced the production of various cytokines in bronchoalveolar fluid. In addition, silibinin prevented the development of airway hyperresponsiveness and attenuated the OVA challenge-induced NF-{kappa}B activation. These findings indicate that silibinin protects against OVA-induced airway inflammation, at least in part via downregulation of NF-{kappa}B activity. Our data support the utility of silibinin as a potential medicine for the treatment of asthma.« less

Background Gly m 5 and Gly m 6 are known to induce severe reactions in soy-allergic patients. For birch pollen (BP)-allergic patients, the Bet v 1 homologous allergen Gly m 4 is also a potential trigger of generalized severe reactions upon soy consumption. Therefore, reliable component-resolved diagnosis of soy allergy is needed. Methods IgE reactivity from sera of 20 patients from a BP environment with reported soy allergy was assessed. Skin prick tests (SPT) with BP and soy drink were performed. Specific IgE for BP, soy, Bet v 1 and Gly m 4 was analyzed by ImmunoCAP. In addition, ISAC microarray profiling was performed. Results Nineteen of 20 patients were BP allergic (positive SPT and/or CAP results for BP extract and Bet v 1). Eighteen soy-allergic patients were tested positive with soy drink in SPT. Soy CAP results were negative in the majority of tests (15/20), whereas 19/20 sera had specific IgE to Gly m 4. In the microarray approach, 14/20 sera displayed Gly m 4-specific IgE, the additional 6 sera had IgE levels below 0.3 ISAC standardized units. The BP-negative serum had Gly m 5- and Gly m 6-specific IgE which correlated with positive soy ImmunoCAP. Conclusions Soy sensitization detected by SPT and Gly m 4 ImmunoCAP were in good qualitative agreement with ISAC results. Soy ImmunoCAP was only specific for Gly m 5 and Gly m 6 sensitization. Gly m 4 ImmunoCAP has a higher sensitivity than ImmunoCAP ISAC. In this patient cohort, Gly m 4 sensitization was linked to the development of severe and generalized allergic reactions upon soy consumption. PMID:23548307

The use of HLA-identical hematopoietic stem cell transplantation (HSCT) demonstrates overall survival rates greater than 75 % for T-B-NK+ severe combined immunodeficiency secondary to pathogenic mutation of recombinase activating genes 1 and 2 (RAG1/2). Limited data exist regarding the use of HSCT in patients with hypomorphic RAG variants marked by greater preservation of RAG activity and associated phenotypes such as granulomatous disease in combination with autoimmunity. We describe a 17-year-old with combined immunodeficiency and immune dysregulation characterized by granulomatous lung disease and autoimmunity secondary to compound heterozygous RAG mutations. A myeloablative reduced toxicity HSCTwas completed using an unrelated bone marrow donor. With the increasing cases of immune dysregulation being discovered with hypomorphic RAG variants, the use of HSCT may advance to the forefront of treatment. This case serves to discuss indications of HSCT, approaches to preparative therapy, and the potential complications in this growing cohort of patients with immune dysregulation and RAG deficiency.

Thalidomide is an effective drug for chronic inflammatory diseases, but the mechanism underlying its immunomodulatory action remains uncertain. Thalidomide has been reported to clinically improve chronic inflammatory granulomatous disorders. In such disorders, the granulomas consist of epithelioid cells, scattered lymphocytes and multinucleated giant cells (MNGC; Langhans-type cells). The present experimental approach permitted the reproduction of MNGC formation from peripheral blood monocytes and examination of thalidomides effect on it. MNGC can be effectively generated from monocytes cultured in the presence of interleukin-4 (IL-4) and macrophage colony-stimulating factor(M-CSF) for 14 days. Thalidomide can inhibit the formation of MNGC in a dose-dependent manner. MNGC formation was partly inhibited by the presence of neutralizing TNF-alpha antibody in the responses induced by IL-4 and M-CSF. Autocrinal TNF-alpha production and modulation of cadhelin expression to regulate cell adhesion might be involved in this inhibitory action of thalidomide. Our results support thalidomides clinical efficacy in the treatment of chronic granulomatous disorders (granulomatosis).

Exogenic allergic alveolitides are caused by organic dusts which contain bacteria, moulds or vegetable and animal antigens. The farmer's lung as a form of the exogenic allergic alveolitis is a rare disease. The uncharacteristic symptomatology in the initial phase and in particular the retarded beginning of the symptom after several hours handicap the timely recognition in an early phase of the disease so that curative therapeutic measures are rarely possible. The cases of the disease are found only at the chronic stage, at the stage of the pulmonary fibrosis. Then the prognosis is unfavourable. In the Central Clinic for Heart and Lung Diseases Bad Berka 1,110 patients with alveolitides and lung fibroses were diagnosed in the period from 1975 to 1988. 306 of them could be clarified as exogenic allergic alveolitis, 61 of them (19.8%) were farmer's lungs.

Methotrexate, a folate antimetabolite, is used to treat atopic dermatitis and psoriasis. Although methotrexate's therapeutic efficacy has been noted in the literature, there are few data on the efficacy of methotrexate treatment for allergic contact dermatitis. To evaluate the efficacy and tolerability of methotrexate in treating allergic contact dermatitis at a single institution, and also to assess methotrexate efficacy in patients with chronic, unavoidable allergen exposure. We performed a retrospective chart review of 32 patients diagnosed with allergic contact dermatitis by positive patch test reactions, and who received treatment with methotrexate from November 2010 to November 2014. Demographic and treatment-associated data were collected from electronic medical records. Ten patients were identified as allergen non-avoiders secondary to their occupation, and were subgrouped as such. Seventy-eight per cent (25/32) of patients showed either a partial or a complete response. Methotrexate had a comparable efficacy rate in the allergen non-avoiders subset, at 10 of 10. Of the 32 patients, 23% (5/22) had complete clearance of their dermatitis, and 1/10 of allergen non-avoiders had complete clearance of their dermatitis. Methotrexate is a well-tolerated and effective treatment for allergic contact dermatitis, and shows comparable efficacy to immunomodulatory agents such as cyclosporine and azathioprine, with robust efficacy despite persistent allergen exposure in patients with allergic contact dermatitis. © 2017 John Wiley & Sons A/S.

Allergic diseases have a significant impact on the quality of life. The aim of the study was to compare sleep parameters of allergic and non-allergic children. Pediatric Sleep Questionnaire was used to asses sleep quality in 202 participants in a 3-year prospective study: in 122 hospitalized (mean age 7.9 +/- 4.7) (F/M 75/47) due to allergic (n = 70) or non-allergic disease (n = 52), and in 80 healthy children (mean age 6.3 +/- 5.0) (F/M 36/44). Of 70 allergic participants, 26 had atopic dermatitis (SCORAD > or = 20); 25 were with bronchial asthma (GINA' criteria) and 19 with IgE-dependent food allergy confirmed by oral food challenge. Of 52 non-allergic patients, 31 children had gastro-esophageal reflux disease and 21 children had recurrent respiratory infection. The group of patients needed significantly more time to fall asleep than controls (17.9 +/- 13.7 vs 12.8 +/- 8.5 min; p < 0.004). Children with food allergy and atopic dermatitis had greatest problems with falling asleep (21.4 +/- 13.8 vs 12.8 +/- 8.5 min; p < 0.006) and 20.4 +/- 14.9 vs 12.8 +/- 8.5 min; p < 0.024). The number of nights of sound sleep without waking up was lower in the study group than in controls (3.5 +/- 2.6 vs 5.0 +/- 2.7; p < 0.0002). Atopic dermatitis and food allergy were found to predispose to sleep disruption most. Snoring history was revealed in 43.4% of patients and in 6.4% of controls (p < 0.0001), being significantly more common in children with bronchial asthma and recurrent respiratory tract infections. Allergic disease was a risk factor for snoring (OR--2.94; 95%CI--1.72-5.05; p < 0.001). As many as 91% of parents did not inform doctors about poor sleep of their children. 1. Allergic diseases are accompanied by different sleep disorders included dyssomnias and parasomnias, e.g. bedtime resistance, disrupted sleep or sleep-disordered breathing. 2.

Hypnosis and the allergic response.

1994-01-01

In recent years our knowledge of the immune system and the pathogenesis of immune disorders has increased. There has been much research on the complex connections between the psyche, the central nervous system and the immune system and the effect of mood on disease processes. This paper reviews the evidence on the effects of hypnosis on the allergic skin test reaction, on allergies, particularly respiratory allergies and hayfever, and on bronchial hyperreactivity and asthma. Hypnosis, which is generally regarded as an altered state of consciousness associated with concentration, relaxation and imagination, and amongst other characteristics an enhanced responsiveness to suggestion, has long been thought to be effective in the amelioration of various bodily disorders. It has seemed that the state of hypnosis is capable of a bridging or mediating function in the supposed dualism between mind and body. There has been great variation in the experimental and clinical procedures such as type of hypnotic intervention employed, the training of subjects and the timing of the intervention. Also, variability in the type of allergen used and its mode of application is evident. But despite these limitations, many of the studies have shown a link between the use of hypnosis and a changed response to an allergic stimulus or to a lessened bronchial hyperreactivity. There is as yet no clear explanation for the effectiveness of hypnosis, but there is some evidence for an influence on the neurovascular component of the allergic response.

Little is known about residence in a rural or farming environment and allergic diseases in Latin America. Cross-sectional study of rural residence and current wheeze, current asthma and current symptoms of allergic rhino-conjunctivitis in 1,804 adolescents (ages 13-14 years) attending 31 schools in urban and rural areas of San Francisco (Córdoba, Argentina). Rural residence was classified as never, previous, and current. Duration of rural residence was categorized as 0, >0 but ≤5 years, and >5 years. Current wheeze, current asthma, and current allergic rhino-conjunctivitis were defined on the basis of responses to an extensively validated questionnaire from the International Study of Asthma and Allergies in Childhood. Logistic regression was used for the multivariable analysis of rural residence and the outcomes of interest. After adjustment for current smoking and other covariates, current rural residence (odds ratio [OR] = 0.15, 95% confidence interval [CI] = 0.03-0.81) and rural residence for >5 years (OR = 0.32, 95%CI = 0.12-0.84) were significantly associated with reduced odds of current wheeze. In a multivariable analysis, current residence in a rural area (OR = 0.52, 95%CI = 0.32-0.86) and rural residence for >5 years (OR = 0.44, 95%CI = 0.26-0.73) were significantly associated with reduced odds of allergic rhino-conjunctivitis. This association was no longer significant after additional adjustment for current residence in a dairy farm, which was significantly associated with reduced odds of allergic rhino-conjunctivitis. Similarly, current regular contact with farm animals was significantly associated with reduced odds of allergic rhino-conjunctivitis. Among Argentinean adolescents, current rural residence and rural residence for >5 years were associated with reduced odds of current wheeze and allergic rhino-conjunctivitis. These potential protective effects may be explained by a dairy farm environment, including regular

Urticaria: "You're Probably Just Allergic to Something".

2016-11-01

Urticaria is a common symptom seen in pediatric patients, and it has multiple allergic and nonallergic causes. Unfortunately, it is far too common that when children present acutely for urticaria, they are told that it is an "allergy." This statement often leads to increased anxiety while the patient waits to be evaluated by an allergist/immunologist. This article discusses the frequency that allergic reactions are involved in urticaria and provides examples of potential nonallergic causes. Additionally, the article discusses approaches to treatment that may be appropriate to initiate in the pediatrician's office or acute setting. This article is intended to provide a broader understanding of urticaria and its management in the outpatient or emergency setting so that we are able to tell our patients more than"you're probably just allergic to something."

Indoor allergens, environmental avoidance, and allergic respiratory disease.

PubMed

Bush, Robert K

2008-01-01

Indoor allergen exposure to sources such as house-dust mites, pets, fungi, and insects plays a significant role in patients with allergic rhinitis and asthma. The identification of the major allergens has led to methods that can quantitate exposure, e.g., immunoassays for Der p 1 in settled dust samples. Sensitization and the development of allergic respiratory disease result from complex genetic and environmental interactions. New paradigms that examine the role of other environmental factors, including exposure to proteases that can activate eosinophils and initiate Th2 responses, and epigenetics, are being explored. Recommendations for specific environmental allergen avoidance measures are discussed for house-dust mites, cockroaches, animal dander, and fungi. Specific measures to reduce indoor allergen exposure when vigorously applied may reduce the risk of sensitization and symptoms of allergic respiratory disease, although further research will be necessary to establish cost-effective approaches.

Multiple chemical sensitivity (MCS) is characterised by adverse effects due to exposure to low levels of chemical substances. The aetiology is unknown, but chemical related respiratory symptoms have been found associated with positive patch test. The purpose of this study was to investigate the relationship between cutaneous reactions from patch testing and self-reported severity of chemical sensitivity to common airborne chemicals. A total of 3460 individuals participating in a general health examination, Health 2006, were patch tested with allergens from the European standard series and screened for chemical sensitivity with a standardised questionnaire dividing the participants into four severity groups of chemical sensitivity. Both allergic and non-allergic cutaneous reactions--defined as irritative, follicular, or doubtful allergic reactions--were analysed in relationship with severity of chemical sensitivity. Associations were controlled for the possible confounding effects of sex, age, asthma, eczema, atopic dermatitis, psychological and social factors, and smoking habits. In unadjusted analyses we found associations between allergic and non-allergic cutaneous reactions on patch testing and the two most severe groups of self-reported sensitivity to airborne chemicals. When adjusting for confounding, associations were weakened, and only non-allergic cutaneous reactions were significantly associated with individuals most severely affected by inhalation of airborne chemicals (odds ratio = 2.5, p = 0.006). Our results suggest that individuals with self-reported chemical sensitivity show increased non-allergic cutaneous reactions based on day 2 readings of patch tests. Copyright © 2011 Elsevier GmbH.

Interstitial granulomatous dermatitis with arthritis (IGDA), also known as Ackerman's syndrome, is a rare cutaneous disease classically characterized by the triad of cutaneous cords, a typical histologic infiltrate mainly constituted by histiocytes and arthritis/connective tissue disease. Here we report the case of IGDA with the typical clinical and histological features in a patient affected by lupus erythematosus. In this article we underline that IGDA may have a variety of different clinical and histological features. The rope sign is typical but infrequent, while histology is usually characteristic and shows a dermal inflammatory infiltrate, with a predominance of histiocytes, localized interstitially and in a palisaded array between collagen fibres, that show signs of degeneration. Clinical and histological differential diagnoses are discussed.

Allergic mice show a reduction in body weight and adiposity with a higher inflammatory response in the adipose tissue similar to obese fat tissue. This study aimed to evaluate whether the low-grade inflammatory milieu of mice with diet-induced mild obesity interferes with the allergic response induced by ovalbumin (OVA). BALB/c mice were divided into four groups: 1) non-allergic (OVA-) mice fed chow diet, 2) allergic (OVA+) mice fed chow diet, 3) OVA- mice fed high-refined carbohydrate-containing (HC) diet, and 4) OVA+ mice fed HC diet. After 5 wk, allergic groups were sensitized with OVA and received a booster 14 d later. All groups received an oral OVA challenge 7 d after the booster. Allergic groups showed increased serum levels of total IgE, anti-OVA IgE, and IgG1; a high disease activity index score; aversion to OVA; and increased intestinal eosinophil infiltration. Non-allergic mild-obese mice also showed aversion to OVA and an increased number of eosinophils in the proximal jejunum. After the allergic challenge, OVA+ mice fed chow diet showed weight loss and lower adiposity in several adipose tissue depots. OVA+ mice fed HC diet showed a loss of fat mass only in the mesenteric adipose tissue. Furthermore, increased levels of TNF, IL-6, and IL-10 were observed in this tissue. Our data show that mild-obese allergic mice do not present severe pathologic features of food allergy similar to those exhibited by lean allergic mice. Mild obesity promoted by HC diet ingestion causes important intestinal disorders that appear to modulate the inflammatory response during the antigen challenge. Copyright © 2016 Elsevier Inc.

Prenatal exposure to bisphenol A (BPA) affects immune system and promotes allergy and asthma in mice, but findings in human studies are limited. We investigated whether prenatal exposure to BPA is associated with increased risk of allergic diseases in infants. We measured BPA concentrations in maternal urine samples collected at delivery from 412 women in Wuhan, China. The occurrence of allergic diseases including eczema and wheeze were assessed at age 6 mo through questionnaires. We used logistic regression to evaluate the association between urinary BPA levels and the risk of allergic diseases. Mothers of infants with allergic diseases had significantly higher urinary BPA levels than those of infants without allergic diseases (median: 2.35 vs. 4.55 µg/l, P = 0.03). Increased risk of infant allergic diseases was associated with creatinine-adjusted maternal urinary BPA concentrations. And this association was limited to females (odds ratio (OR) = 1.36; 95% confidence interval (CI): 1.10-1.79) rather than males. After stratification by maternal age, the association was only significant in infants of mothers who were younger than 25 y old (OR = 1.90; 95% CI: 1.09-3.29). Prenatal exposure to BPA may potentially increase the risk of allergic diseases at very early life in female infants.

The objective of this study was to evaluate the prevalence of asthma, allergic rhinitis, and atopic dermatitis, as well as the risk factors of wheezing among young adults in the Korean military. Young military conscripts in five areas completed a modified International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. For subjects with current wheeze in one sample area, baseline spirometry and bronchodilator response were measured. For subjects without a significant response to bronchodilator (improvement in FEV1 of more than 200 mL and 12%), methacholine challenge tests (MCT) were also performed. Of 3,359 subjects that completed the questionnaire, 354 (10.5%) had current wheeze, 471 (14.0%) had current allergic rhinitis, and 326 (9.7%) had current eczema. Current wheeze was associated with family history of allergic disease, overweight, current smoking, allergic rhinitis, and atopic dermatitis. Of 36 subjects with current wheeze who underwent PFT with or without MCT in the Anyang area, 24 (66.7%) were confirmed to have current asthma. In conclusion, the prevalence of allergic disease in young adults of Korean military is not low, and the risk factors of wheezing include family history of allergic disease, overweight, current smoking, allergic rhinitis, and atopic dermatitis.

1998-08-01

Since the highest risk for the development of atopic disease is in early life, environmental risk factors need to be separated from the genetic component in this high risk period. Adoptees removed at birth and placed in adoptive families present a way to separate environmental and genetic factors at this early susceptible age. An opportunity for a pilot study of asthma and allergic rhinitis in adoptive families was presented when a psychiatrist (RC) was planning a behavioral study of young adult adoptees and their adoptive parents. A detailed questionnaire about allergic rhinitis and asthma was added after the psychiatrists' interview. Placement was not influenced by a history of allergy in adoptive or natural parents. The adoptee and at least one adoptive parent completed questionnaires in 367 families. The adoptees had been removed at birth and placed in the adoptive family within 3 months (83% within 1 month). Compared with adoptive families without asthma or allergic rhinitis, an adoptive mother with asthma or rhinitis, when the adoptive father was not affected, increased the risk for asthma in the adoptee (OR = 3.2, P < .0005). Asthma in the adoptive mother alone (OR = 3.2, P < .005) and allergic rhinitis alone (OR = 3.4, P < .005) increased the risk for asthma in the adoptee. Adoptive father asthma or allergic rhinitis showed a trend toward increased asthma in the adoptee (OR = 1.9, P < .1). This should be considered a pilot or feasibility study since subjects could not be examined or tested. Finding a risk for atopic respiratory disease or asthma associated with adoption by parents with asthma or allergic rhinitis suggests that further well planned adoptee studies should be made.

This survey included questions to focus the investigation in the use of a Iternative medicine for the treatment of any allergic disease. The data analysis was done by descriptive statistics. Four hundred one questionnaires were applied. The average age of the patients was of 14 years (range from 1 to 73 years). Fourty-seven percent (189 patients) were female and 58.2% (212 patients) were male. The diagnoses included: allergic rhinitis in 215 patients (53.6), asthma in 97 (24.2%), rhinitis and asthma in 73 (18.2) and atopic dermatitis in 16 (4%). Out of the patients 34.4% (138) had used at least one type of alternative medicine for the treatment of their allergic disease. Homeopathy was the most commonly used type of alternative medicine (78.2%), followed by the natural medicine (31.5%). Alternative medicine for the treatment of allergic diseases is frequent in patients who attend to this center. Homeopathy and the natural medicine are the most used.

Regulatory T cells (Treg) represent a promising target for novel treatment strategies in patients with inflammatory/allergic diseases. A soluble derivate of the Treg surface molecule glycoprotein A repetitions predominant (sGARP) has strong anti-inflammatory and regulatory effects on human cells in vitro as well as in vivo through de novo induction of peripheral Treg. The aim of this study was to investigate the immunomodulatory function of sGARP and its possible role as a new therapeutic option in allergic diseases using a humanized mouse model. To analyze the therapeutic effects of sGARP, adult NOD/Scidγc(-/-) (NSG) mice received peripheral blood mononuclear cells (PBMC) derived from allergic patients with sensitization against birch allergen. Subsequently, allergic inflammation was induced in the presence of Treg alone or in combination with sGARP. In comparison with mice that received Treg alone, additional treatment with sGARP reduced airway hyperresponsiveness (AHR), influx of neutrophils and macrophages into the bronchoalveolar lavage (BAL), and human CD45(+) cells in the lungs. Furthermore, the numbers of mucus-producing goblet cells and inflammatory cell infiltrates were reduced. To elucidate whether the mechanism of action of sGARP involves the TGF-β receptor pathway, mice additionally received anti-TGF-β receptor II (TGF-βRII) antibodies. Blocking the signaling of TGF-β through TGF-βRII abrogated the anti-inflammatory effects of sGARP, confirming its essential role in inhibiting the allergic inflammation. Induction of peripheral tolerance via sGARP is a promising potential approach to treat allergic airway diseases. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Aeroallergens, Allergic Disease, and Climate Change: Impacts and Adaptation

PubMed Central

Reid, Colleen E.

2009-01-01

Recent research has shown that there are many effects of climate change on aeroallergens and thus allergic diseases in humans. Increased atmospheric carbon dioxide concentration acts as a fertilizer for plant growth. The fertilizing effects of carbon dioxide, as well as increased temperatures from climate change, increase pollen production and the allergen content of pollen grains. In addition, higher temperatures are changing the timing and duration of the pollen season. As regional climates change, plants can move into new areas and changes in atmospheric circulation can blow pollen- and spore-containing dust to new areas, thus introducing people to allergens to which they have not been exposed previously. Climate change also influences the concentrations of airborne pollutants, which alone, and in conjunction with aeroallergens, can exacerbate asthma or other respiratory illnesses. The few epidemiological analyses of meteorological factors, aeroallergens, and allergic diseases demonstrate the pathways through which climate can exert its influence on aeroallergens and allergic diseases. In addition to the need for more research, there is the imperative to take preventive and adaptive actions to address the onset and exacerbation of allergic diseases associated with climate variability and change.

Probiotics for the prevention or treatment of allergic diseases.

PubMed

Prescott, Susan L; Björkstén, Bengt

2007-08-01

This review addresses the effects of probiotic bacteria on immune development and the role in the treatment and prevention of allergic disease. Although there is a sound theoretical basis for anticipating benefits, there are currently insufficient data to recommend probiotics as a part of standard therapy in any allergic conditions. Furthermore, although there have been several studies to show a benefit in prevention of atopic eczema, other studies have failed to support this. None of the studies has shown any clear preventive effect on sensitization, nor any allergic disease other than eczema. The term "probiotic" is often used loosely to include bacterial strains with little documented immunomodulatory capacity or controlled studies to support the claims. It is not known whether effects in experimental systems have any clinical relevance. Finally, very little is known about this large, complex internal ecosystem. Explanations for the varied results between studies include host factors (including genetic differences in microbial responses and allergic predisposition) and other environmental factors, such as general microbial burden, individual microbiota, diet (including consumption of prebiotic substances), and treatment with antibiotics. As more studies are completed, these factors are likely to make robust meta-analyses problematic to perform.

Accumulating evidence is indicating that hormonal factors play a role in new-onset allergic rhinitis and asthma after puberty. To determine whether age at menarche and use of hormonal contraceptives predict new-onset allergic rhinitis and asthma after puberty in young German women. A prospective community-based cohort study followed 1,191 girls 9 to 11 years old to early adulthood (19-24 years old). Self-administrated questionnaires concerning age at menarche, use of hormonal contraceptives, and status and age at onset of physician-diagnosed allergic rhinitis and asthma were collected at 16 to 18 and 19 to 24 years of age. Logistic regression models were used to analyze the incidence of asthma and allergic rhinitis after puberty and pooled estimates were obtained from the final model. Eleven percent of girls developed allergic rhinitis after menarche and 3% reported new-onset asthma. Late menarche (>13 years of age) was statistically significantly inversely related to allergic rhinitis (adjusted odds ratio [OR] 0.32, 95% confidence interval [CI] 0.14-0.74) but did not reach the level of statistical significance for asthma (OR 0.32, 95% CI 0.07-1.42). Use of hormonal contraceptives was inversely associated with new-onset allergic rhinitis (OR 0.14, 95% CI 0.08-0.23) and asthma (OR 0.27, 95% CI 0.12-0.58) after puberty. This study shows that girls with late onset of menarche are less likely to develop allergic rhinitis after puberty compared with those who have menarche at an average age. These findings also suggest that, in addition to endogenous hormones, hormonal contraceptives play a role and might protect young women from allergies and asthma.

Asthma and allergic rhinitis are the two most common chronic disorders in childhood and adolescence. To date, no study has examined the impact of comorbid allergic rhinitis on asthma control in children. To examine the prevalence of allergic rhinitis in children with asthma, and the impact of the disease and its treatment on asthma control. A cross-sectional survey in 203 children with asthma (5-18 years) using validated questionnaires on rhinitis symptoms (stuffy or runny nose outside a cold) and its treatment, and the paediatric Asthma Control Questionnaire (ACQ). Fraction of nitric oxide in exhaled air (FeNO) was measured with a Niox Mino analyser; total and specific IgE levels were assessed by the Immunocap system. 157 children (76.2%) had symptoms of allergic rhinitis but only 88 of these (56.1%) had been diagnosed with the condition by a physician. ACQ scores were worse in children with allergic rhinitis than in those without the condition (p=0.012). An ACQ score ≥ 1.0 (incomplete asthma control) was significantly more likely in children with allergic rhinitis than in those without (OR 2.74, 95% CI 1.28 to 5.91, p=0.0081), also after adjustment for FeNO levels and total serum IgE. After adjustment for nasal corticosteroid therapy, allergic rhinitis was no longer associated with incomplete asthma control (OR 0.72, 95% CI 0.47 to 1.12, p=0.150). Allergic rhinitis is common in children with asthma, and has a major impact on asthma control. The authors hypothesise that recognition and treatment of this condition with nasal corticosteroids may improve asthma control in children, but randomised clinical trials are needed to test this hypothesis.

Little is known about the associations between allergic disease, sleep-disordered breathing (SDB), and childhood nocturnal enuresis (NE). We examined whether allergic disease and SDB were associated with childhood NE. Data were assessed from the 2007-2012 Taiwan National Health Insurance Research Database. We enrolled 4308 children aged 5-18 years having NE diagnosis and age- and sex-matched 4308 children as the control group. The odds ratios of NE were calculated to determine an association with preexisting allergic disease and SDB. A total of 8616 children were included in the analysis. Prevalence of allergic diseases and SDB was significantly higher for the NE group than the control group (all p < 0.001). After adjusting odds ratios for potential confounding factors, except asthma, children with allergic rhinitis, atopic dermatitis, allergic conjunctivitis, and obstructive sleep apnea (OSA) had significantly higher odds of NE compared with children never diagnosed. With stratification for sex, girls with allergic rhinitis, atopic dermatitis, allergic conjunctivitis, OSA, and snoring had significantly higher odds of NE, compared with girls never diagnosed. Only boys with allergic rhinitis and OSA were associated with increased odds of NE. With stratification for age, children aged 5-12 years with allergic rhinitis, atopic dermatitis, allergic conjunctivitis, and OSA had significantly higher odds of NE compared with those never diagnosed. Odds of NE increased with the number of comorbid allergic diseases. Allergic diseases and SDB are associated with increased odds of childhood NE. The odds of NE increased with the number of comorbid allergic diseases present.

Global increases in allergic respiratory disease: the possible role of diesel exhaust particles.

Reading this article will enable the readers to recognize and evaluate i e potential relationship between allergic respiratory disease and polyaromatic hydrocarbons as air pollutants from industrial and automotive fuel sources. In this article we review the long-term trends in the prevalence of allergic airway diseases (rhinitis and asthma). We then examine the epidemiologic and other research data relating to the role that hydrocarbon fuel emissions may have had on allergic respiratory disease. Published literature on the relationship between specific air pollutants and trends in allergic respiratory disease were reviewed. Reports of research on pollutant effects on allergic antibody (IgE) were also studied. In both cases, the Melvyl-Medline database since 1975 was used for literature searches. Older references were identified from the bibliographies of relevant articles and books and with the help of the rare books collection at UCLA's Louis M. Darling Biomedical library. Examination of the historical record indicates that allergic rhinitis and allergic asthma have significantly increased in prevalence over the past two centuries. Although the reasons for this increase are not fully elucidated, epidemiologic data suggest that certain pollutants such as those produced from the burning of fossil fuels may have played an important role in the prevalence changes. Also important are studies showing that diesel exhaust, a prototypical fossil fuel, is able to enhance in vitro and in vivo IgE production. Increased levels of the compounds resulting from fossil fuel combustion may be partly responsible for the increased prevalence of allergic respiratory disease. If the nature of these compounds and the mechanisms by which they exacerbate allergic disease can be identified, steps can be taken to reduce the production or the impact of these allergy producing compounds.

Human Helminths and Allergic Disease: The Hygiene Hypothesis and Beyond

PubMed Central

Santiago, Helton C.; Nutman, Thomas B.

2016-01-01

There is much debate about the interaction between helminths and allergic disease. The “Hygiene Hypothesis,” a very popular concept among scientists and the lay public, states that infections, especially during childhood, can protect against allergic diseases. Indeed, helminth infections are known to induce regulatory responses in the host that can help the control of inflammation (including allergic inflammation). However, these infections also induce type-2-associated immune responses including helminth-specific IgE that can cross-react against environmental allergens and mediate IgE-driven effector responses. Thus, it is the delicate balance between the parasites' anti- and pro-allergenic effects that define the helminth/allergy interface. PMID:27573628

Exposure to Particulate Hexavalent Chromium Exacerbates Allergic Asthma Pathology

Airborne hexavalent chromate, Cr(VI), has been identified by the Environmental Protection Agency as a possible health threat in urban areas, due to the carcinogenic potential of some of its forms. Particulate chromates are produced in many different industrial settings, with high levels of aerosolized forms historically documented. Along with an increased risk of lung cancer, a high incidence of allergic asthma has been reported in workers exposed to certain inhaled particulate Cr(VI) compounds. However, a direct causal association between Cr(VI) and allergic asthma has not been established. We recently showed that inhaled particulate Cr(VI) induces an innate neutrophilic inflammatory response in BALB/c mice. In the current studies we investigated how the inflammation induced by inhaled particulate Cr(VI) might alter the pathology of an allergic asthmatic response. We used a well-established mouse model of allergic asthma. Groups of ovalbumin protein (OVA)-primed mice were challenged either with OVA alone, or with a combination of OVA and particulate zinc chromate, and various parameters associated with asthmatic responses were measured. Co-exposure to particulate Cr(VI) and OVA mediated a mixed form of asthma in which both eosinophils and neutrophils are present in airways, tissue pathology is markedly exacerbated, and airway hyperresponsiveness is significantly increased. Taken together these findings suggest that inhalation of particulate forms of Cr(VI) may augment the severity of ongoing allergic asthma, as well as alter its phenotype. Such findings may have implications for asthmatics in settings in which airborne particulate Cr(VI) compounds are present at high levels. PMID:22178736

Allergic rhinitis is an inflammatory disorder of the nasal mucosa, characterized by symptoms of itching, rhinorrhea, nasal congestion and sneezing induced by an IgE-mediated response. In Mexico we have reports of prevalence, with fluctuations of 5.5% to 47.7% with the question of rhinitis symptoms the past 12 months. To determine the prevalence of allergic rhinitis in schoolchildren from various states of Mexico. A descriptive study of prevalence in which a questionnaire was applied to preschool, elementary-, middle- and high-school population. It was performed in four cities in four states of Mexico: Puebla, Puebla, Tulancingo, Hidalgo, Tlaxcala, Tlaxcala and Cancun, Quintana Roo. Parents answered questionnaires of preschool and elementary school and middle- and high-school students answered their questionnaires. The study was conducted from June 2014 to January 2015. The instrument used was: questionnaire diagnosis of allergic rhinitis for epidemiological studies. Of the surveys, 8,159 completed questionnaires were obtained, in the city of Puebla: 2,267, Tulancingo, Hidalgo: 2,478, Tlaxcala, Tlaxcala: 2,574, Cancun, Quintana Roo: 840; total male: 4,190 (51%). The overall average rate of prevalence of allergic rhinitis among four states including all respondents ages was 15%. With the use of the questionnaire diagnosis of allergic rhinitis for epidemiological studies in the four cities in four different states, we found a prevalence of allergic rhinitis of 15% in ≥13 yearpopulation and 13% in ≤12 year-old children.

Allergic rhinitis is a complex polygenic disorder of the upper respiratory tract. Given that proinflammatory cytokines such as tumor necrosis factor (TNF) and interleukin (IL) 1 seem to play a role in the development of allergic rhinitis, we evaluated the associations between various single-nucleotide polymorphisms (SNPs) of the TNF and IL1 genes in a case-control study. The study population comprised 98 patients with allergic rhinitis. Genotyping was performed using polymerase chain reaction with sequence-specific primers for 2 TNFA promoter variants (rs1800629 and rs361525), 1 variant in the promoter region of IL1A (rs1800587), 2 SNPs in the IL1B gene (rs16944 and rs1 143634), 1 variant in the IL1 receptor (rs2234650), and 1 in IL1RA (rs315952). Patients who were homozygous for the T allele of rs16944 in IL1B had an 8.1-fold greater risk of allergic rhinitis than those with the C allele. In TNFA, a significant relationship was also detected between rs1800629 and rs361525 and allergic rhinitis. Except for rs1800587 in IL1A and rs315952 in IL1RA, significant differences were found between the patient and control groups for all other SNPs. We found that allelic variants in the TNFA and IL1 genes were not only associated with the risk of developing allergic rhinitis, but also affected disease course and severity.

Contact sensitization is common and affects up to 20% of the general population. The clinical manifestation of contact sensitization is allergic contact dermatitis. This is a clinical expression that is sometimes difficult to distinguish from other types of dermatitis, for example irritant and atopic dermatitis. Several studies have examined the pathogenesis and severity of allergic contact dermatitis by measuring the absence or presence of various biomarkers. In this review, we provide a non-systematic overview of biomarkers that have been studied in allergic contact dermatitis. These include genetic variations and mutations, inflammatory mediators, alarmins, proteases, immunoproteomics, lipids, natural moisturizing factors, tight junctions, and antimicrobial peptides. We conclude that, despite the enormous amount of data, convincing specific biomarkers for allergic contact dermatitis are yet to be described. © 2017 John Wiley & Sons A/S.

Phosphodiesterase 3 (PDE3) and PDE4 regulate levels of cyclic AMP, which are critical in various cell types involved in allergic airway inflammation. Although PDE4 inhibition attenuates allergic airway inflammation, reported side effects preclude its application as an antiasthma drug in humans. Case reports showed that enoximone, which is a smooth muscle relaxant that inhibits PDE3, is beneficial and lifesaving in status asthmaticus and is well tolerated. However, clinical observations also showed antiinflammatory effects of PDE3 inhibition. In this study, we investigated the role of PDE3 in a house dust mite–driven (HDM-driven) allergic airway inflammation (AAI) model that is characterized by T helper 2 cell activation, eosinophilia, and reduced mucosal barrier function. Compared with wild-type (WT) littermates, mice with a targeted deletion of the PDE3A or PDE3B gene showed significantly reduced HDM-driven AAI. Therapeutic intervention in WT mice showed that all hallmarks of HDM-driven AAI were abrogated by the PDE3 inhibitors enoximone and milrinone. Importantly, we found that enoximone also reduced the upregulation of the CD11b integrin on mouse and human eosinophils in vitro, which is crucial for their recruitment during allergic inflammation. This study provides evidence for a hitherto unknown antiinflammatory role of PDE3 inhibition in allergic airway inflammation and offers a potentially novel treatment approach. PMID:29367458

Trematodes belonging to the family Eucotylidae are parasites of the kidney and ureter, and affect several bird species. However, psittacines have not been identified as hosts of these parasites. Three birds, an adult female blue and gold macaw (Ara ararauna), an adult female blue-winged macaw (Propyrrhura maracana) and an adult male white-eared parakeet (Pyrrhura leucotis) were admitted at the Veterinary Hospital of the Fundação Zoo-Botânica de Belo Horizonte, Brazil (FZB/BH). All three birds had severe dehydration and cachexia. The blue and gold macaw presented with dyspnea, apathy, and incoordination. Blood cell counts indicated discrete anemia and leucopenia. Blood biochemistry revealed significant increase in levels of uric acid (61 mg/dl) and blood urea nitrogen (22 mg/dl). The bird died within 24 h after admission. The other two birds were admitted with similar clinical signs, but died prior to a complete clinical examination. At the necropsy, in all the three birds, the kidneys were enlarged with brown-yellowish discoloration and irregular cortical surface. On the cut surface, there was a brown-yellowish material with few visible parasites flowing out of the parenchyma. When fragments of the kidneys were placed in 10% formalin, a large number of trematodes came out of the renal parenchyma. The parasites were identified as Paratanaisia robusta infecting all three birds, and P. bragai infecting the blue-winged macaw and the white-eared parakeet. Histologically, there was an interstitial, multifocal to coalescent, lymphoplasmacytic infiltrate with some epithelioid macrophages, and a few heterophils, characterizing a granulomatous nephritis. Adult worms and eggs were observed within dilated tubules and in the renal pelvis. In the blue and gold macaw, some parasite eggs were located interstitially associated with an intense adjacent granulomatous reaction.

Completion of the human genome project and rapid progress in genetics and bioinformatics have enabled the development of large public databases, which include genetic and genomic data linked to clinical health data. With the massive amount of information available, clinicians and researchers have the unique opportunity to complement and integrate their daily practice with the existing resources to clarify the underlying etiology of complex phenotypes such as allergic diseases. The genome itself is now often utilized as a starting point for many studies and multiple innovative approaches have emerged applying genetic/genomic strategies to key questions in the field of allergy and immunology. There have been several successes, which have uncovered new insights into the biologic underpinnings of allergic disorders. Herein, we will provide an in depth review of genomic approaches to identifying genes and biologic networks involved in allergic diseases. We will discuss genetic and phenotypic variation, statistical approaches for gene discovery, public databases, functional genomics, clinical implications, and the challenges that remain.

Allergic responses are enhanced by stress, whereas they are reduced by laughter in atopic eczema patients. Emotion with tears decreases plasma IL-6 levels in patients with rheumatoid arthritis. Thus, the effect of emotion with tears on allergic responses in patients with atopic eczema was studied. Sixty patients with atopic eczema having latex allergy viewed both the weather information video and the heart-warming movie, Kramer vs. Kramer. Just before and immediately after viewing each video, allergic responses to latex were measured. Viewing the weather information video did not cause emotion with tears in any patients, and it failed to modulate allergic responses. In contrast, viewing Kramer vs. Kramer caused emotion with tears in 44 of 60 patients, and it reduced allergic skin wheal responses to latex and latex-specific IgE production in them. Emotion with tears reduced allergic responses, and it may be useful in the treatment of allergic diseases.

Contact dermatitis to cosmetics is a common problem in the general population, although its prevalence appears to be underestimated. We reviewed cases of allergic contact dermatitis to cosmetics diagnosed in our dermatology department over a 7-year period with a view to identifying the allergens responsible, the frequency of occurrence of these allergens, and the cosmetic products implicated. Using the database of the skin allergy department, we undertook a search of all cases of allergic contact dermatitis to cosmetics diagnosed in our department from January 2000 through October 2007. In this period, patch tests were carried out on 2,485 patients, of whom 740 were diagnosed with allergic contact dermatitis and the cause was cosmetics in 202 of these patients (170 women and 32 men), who accounted for 27.3 % of all cases. A total of 315 positive results were found for 46 different allergens. Allergens most often responsible for contact dermatitis in a cosmetics user were methylisothiazolinone (19 %), paraphenylenediamine (15.2 %), and fragrance mixtures (7.8 %). Acrylates were the most common allergens in cases of occupational disease. Half of the positive results were obtained with the standard battery of the Spanish Group for Research Into Dermatitis and Skin Allergies (GEIDAC). The cosmetic products most often implicated among cosmetics users were hair dyes (18.5 %), gels/soaps (15.7 %), and moisturizers (12.7 %). Most patients affected were women. Preservatives, paraphenylenediamine, and fragrances were the most frequently detected cosmetic allergens, in line with previous reports in the literature. Finally, in order to detect new cosmetic allergens, cooperation between physicians and cosmetics producers is needed.

Allergic proctocolitis is a disease that affects infants in the first months. The change in feed is the primary factor for clinical improvement and maintenance of the nutritional status of the infant. Study the anthropometric evolution of infants with allergic proctocolitis at diagnosis and 1 to 6 months after nutritional intervention. A retrospective cohort of infants with allergic proctocolitis diagnosis followed at the Pediatric Gastroenterology Institute of São Paulo (IGASTROPED), Brazil. The database with clinical, therapeutic and anthropometric data was obtained from medical records of outpatient infants. The therapeutic intervention was characterized by 1) exclusive breastfeeding with maternal exclusion diet of the six allergens (EBF-MED) or 2) no breastfeeding and use of hypoallergenic formulas. Of the 44 infants diagnosed with allergic proctocolitis, 23 were female. The median age of the infants was 3.5 months at the time of admission and 6 months after the intervention. The main clinical complaint was hematochezia with or without other symptoms of allergic proctocolitis. No difference was shown in the infants anthropometric evaluation between the two diets. The duration of the allergic proctocolitis did not induce worsening of the infants nutritional status. Importantly, both nutritional interventions were able to keep the infants within the growth channel and resulted in the total clinical symptoms remission. Considering the fundamental mother-child link promoted by breastfeeding, the present data highlights the beneficial role of EBF-MED on the nutritional status of infants diagnosed with allergic proctocolitis in addition to the lower cost that breastfeeding brings compared the use of hypoallergenic formulas.

Angiotensin-converting enzyme (ACE) I/D polymorphism is a risk factor of allergic rhinitis.

Some previous studies and meta-analysis investigated the association between ACE I/D polymorphism and allergic rhinitis risk. However, the results were conflicting. This meta-analysis, therefore, was performed to evaluate the association between ACE I/D polymorphism and allergic rhinitis risk. Online electronic databases (PubMed and EMBASE) were searched. The strength was evaluated by calculating the OR and 95% CI. Five studies were finally included in this meta-analysis. These studies included 681 cases and 629 controls. ACE I/D polymorphism was significantly associated with allergic rhinitis risk (OR = 1.17; 95% CI 1.07 - 1.29; P = 0.001). In the subgroup analysis of race, Asians showed the increased allergic rhinitis risk (OR = 1.15; 95% CI 1.02 - 1.30; P = 0.03). In a stratified analysis by age, adults with ACE I/D polymorphism showed the increased allergic rhinitis risk (OR = 1.16; 95% CI 1.04 - 1.29; P = 0.006). However, children did not have the significantly increased allergic rhinitis risk (OR = 1.24; 95% CI 0.99 - 1.56; P = 0.06). In conclusion, this meta-analysis indicated that ACE I/D polymorphism was significantly associated with allergic rhinitis risk.

Allergic diseases such as asthma, allergic rhinitis, atopic dermatitis, and food allergy, are most common chronic, noncommunicable diseases in childhood. In the past few decades, the prevalence has increased abruptly worldwide. There are 2 possible explanations for the rising prevalence of allergic diseases worldwide, that an increased disease-awareness of physician, patient, or caregivers, and an abrupt exposure to unknown hazards. Unfortunately, the underlying mechanisms remain largely unknown. Despite the continuing efforts worldwide, the etiologies and rising prevalence remain unclear. Thus, it is important to identify and control risk factors in the susceptible individual for the best prevention and management. Genetic susceptibility or environments may be a potential background for the development of allergic disease, however they alone cannot explain the rising prevalence worldwide. There is growing evidence that epigenetic change depends on the gene, environment, and their interactions, may induce a long-lasting altered gene expression and the consequent development of allergic diseases. In epigenetic mechanisms, environmental tobacco smoke (ETS) exposure during critical period (i.e., during pregnancy and early life) are considered as a potential cause of the development of childhood allergic diseases. However, the causal relationship is still unclear. This review aimed to highlight the impact of ETS exposure during the perinatal period on the development of childhood allergic diseases and to propose a future research direction.

Allergic diseases are triggered by Th2-mediated immune reactions to allergens and orchestrated by various immunological factors, including immune cells and cytokines. Although many reports have suggested that childhood is the critical period in the onset of allergic diseases and aging leads to alter the susceptibility of an individual to allergic diseases, age-related changes in various immunological factors in healthy individuals as well as their difference between healthy and allergic children have not yet been established. We investigated the ratio of Th1/Th2 cells and the levels of 22 allergy-related cytokines across all age groups in individuals who were classified as clinically non-atopic and healthy. We also examined their differences between healthy and allergic children to evaluate immunological changes induced by the development of allergic diseases during childhood. The Th1/Th2 ratio rose gradually during the growth period including childhood, reaching peak values in the twenties-thirties age group. Th1/Th2 ratios were significantly lower in allergic children than in healthy controls, whereas 14 of 22 cytokines were significantly higher in allergic children than in healthy controls. On the other hand, there were no differences in Th1/Th2 ratios and cytokines between healthy and allergic adolescents. In this study, age-related changes in Th1/Th2 ratios were found in normal controls across all age groups, and decreases in Th1/Th2 ratio were observed with increasing of 14 cytokines in allergic children. The results of this study may be helpful as reference values for both monitoring immunological changes according to aging in healthy individuals and distinguishing between normal and allergic subjects in terms of immune cells and soluble factors.

Allergic asthma and allergic rhinitis/conjunctivitis are characterized by a T(H)2-dominated immune response associated with increased serum IgE levels in response to inhaled allergens. Because IgE is a key player in the induction and maintenance of allergic inflammation, it represents a prime target for therapeutic intervention. However, our understanding of IgE biology remains fragmentary. This article puts together our current knowledge on IgE in allergic airway diseases with a special focus on the identity of IgE-secreting cells ("who"), their location ("where"), and the circumstances in which they are induced ("when"). We further consider the therapeutic implications of the insights gained. Copyright © 2011 American Academy of Allergy, Asthma & Immunology. Published by Mosby, Inc. All rights reserved.

Allergic diseases cause great impact on the health related quality of life in children and adolescents, resulting in increased school absenteeism and deficiencies in school performance. Although the bibliographic framework on allergic diseases is wide, in our country, there are no guidelines for proper management of the allergic child at school. It is necessary to establish guidelines for coordinated action among the educational community, the families, the pediatrician, the health team and governmental and non-governmental authorities. This position paper aims to provide information about the impact of allergic diseases on school activities, establish standards of competence of the various stakeholders at school and consider the legal framework for the intervention of the school staff about the child with allergies at school.

Granulomatous mastitis is a rare condition of unknown aetiology. The great majority of cases has not been associated with bacterial pathogens if women with mammary tuberculosis are excluded. We noted that some women in Auckland with a histological diagnosis of granulomatous mastitis had both microbiological and histological evidence of corynebacteria infection and aimed to study this further. Thirty-four women were reviewed who presented with inflammatory breast disease and had microbiological specimens from which corynebacteria were isolated and/or histological specimens containing coryneform bacteria. These 34 cases were compared with 28 controls with similar histology but no evidence of corynebacteria infection. Twenty-seven (79%) of the cases and 21 (75%) of the controls had histological and/or cytological evidence of suppurative granulomas. Fourteen of the 34 cases also had Gram-positive bacilli (GPB), recognisable as coryneform bacteria, in histological sections. In all cases the bacilli were confined to empty spaces, consistent with dissolved lipid, and were surrounded by neutrophils and, frequently, suppurative granulomas. Corynebacterium species were isolated from 52 of 116 microbiological specimens taken from the 34 cases. Forty of these 52 cultures were pure. Twenty-four of the cultures were further classified biochemically and using 16S rRNA gene sequencing. Twenty of the 24 were lipophilic Corynebacterium species and 14 were identified as Corynebacterium kroppenstedtii. The cases were more likely to present with fever or neutrophilia and more often formed sinuses than the controls but other clinical features were similar. Maori and Pacific Islanders accounted for 77% of the women across both groups. We suggest granulomatous mastitis can be associated with corynebacteria infection, particularly infection by C. kroppenstedtii. The significance of this finding, which has previously been described in only a single case report, is discussed.

Therapeutic Targeting of Eosinophil Adhesion and Accumulation in Allergic Conjunctivitis

Considerable evidence indicates that eosinophils are important effectors of ocular allergy. Increased worldwide prevalence of allergic eye pathologies has stimulated the identification of novel drug targets, including eosinophils and adhesion molecules. Accumulation of eosinophils in the eye is a key event in the onset and maintenance of allergic inflammation and is mediated by different adhesion molecules. Antihistamines with multiple mechanisms of action can be effective during the early and late phases of allergic conjunctivitis by blocking the interaction between β1 integrins and vascular cell adhesion molecule (VCAM)-1. Small molecule antagonists that target key elements in the process of eosinophil recruitment have been identified and reinforce the validity of α4β1 integrin as a therapeutic target. Glucocorticoids are among the most effective drugs for ocular allergy, but their use is limited by adverse effects. Novel dissociated glucocorticoids can prevent eosinophil accumulation and induce apoptosis of eosinophils, making them promising candidates for ophthalmic drugs. This article reviews recent understanding of the role of adhesion molecules in eosinophil recruitment in the inflamed conjunctiva along with effective treatments for allergic conjunctivitis.

Despite links between maternal and child health status, evidence on the association between gum infection in pregnant mothers and childhood allergies is scarce. We aim to evaluate the risk of developing allergy in children born to periodontal mothers in a nationwide study. We conducted a 9-year population-based, retrospective cohort study using Taiwan's National Health Insurance database. A study cohort of 42,217 newborns born to mothers with periodontal disease during pregnancy was identified in 2001 and matched with 42,334 babies born to mothers without any infection (control) by mother's age at delivery and baby sex. With a follow-up period from 2001 to 2010, we observed the incidence of allergic rhinitis (AR), allergic conjunctivitis (AC), and eczema in these children. Cox proportional hazards regression models were performed with premature deaths as competing risk for the estimation of allergic disease risks. Nine-year cumulative incidences were the highest among children born to periodontal mothers; they reached 46.8%, 24.2%, and 40.4% (vs. 39.5%, 18.3% and 34.8% in control) for AR, AC, and eczema, respectively. Our results showed moderately increased risks for the allergies in children born to periodontal mothers relative to their matched non-inflammatory control (adjusted HRs: 1.17, 95% CI: 1.15-1.20; 1.27, 1.24-1.31; 1.14, 1.12-1.17, respectively). Because the impact of food consumption and living environment cannot be considered using insurance data, we attempted to control it by adjusting for parental income and mother's residential area. Overall cumulative incidence and risks of children born to periodontal mothers for AR, AC, and eczema are significantly higher than those born to non-inflammatory mothers. Gum infection in women during pregnancy is an independent risk factor for allergic diseases in children, thus its intergenerational consequences should be considered in gestational care.

Human Helminths and Allergic Disease: The Hygiene Hypothesis and Beyond.

PubMed

Santiago, Helton C; Nutman, Thomas B

2016-10-05

There is much debate about the interaction between helminths and allergic disease. The "Hygiene Hypothesis," a very popular concept among scientists and the lay public, states that infections, especially during childhood, can protect against allergic diseases. Indeed, helminth infections are known to induce regulatory responses in the host that can help the control of inflammation (including allergic inflammation). However, these infections also induce type-2-associated immune responses including helminth-specific IgE that can cross-react against environmental allergens and mediate IgE-driven effector responses. Thus, it is the delicate balance between the parasites' anti- and pro-allergenic effects that define the helminth/allergy interface. © The American Society of Tropical Medicine and Hygiene.

Idiopathic granulomatous lobular mastitis (IGLM), also known as idiopathic granulomatous mastitis, is a rare chronic inflammatory lesion of the breast that can clinically and radiographically mimic breast carcinoma. The aim of this study was to describe the radiological imaging and clinical features of IGLM in order to better differentiate this disorder from breast cancer. We performed a retrospective analysis of the clinical and radiographic features of 11 women with a total of 12 IGLM lesions. The ages of these women ranged between 29 and 42 years, with a mean age of 34.8 years. Ten patients were examined by both mammography and sonography and one by sonography alone. The sites that were the most frequently involved were the peripheral (6/12), diffuse, (3/12), and subareolar (3/12) regions of the breast. The patient mammograms showed irregular ill-defined masses (7/11), diffuse increased densities (3/11), and one oval obscured mass. In addition, patient sonograms showed irregular tubular lesions (7/12) or lobulated masses with minimal parenchymal distortion (2/12), parenchymal distortion without definite mass lesions (2/12), and one oval mass. Subcutaneous fat obliteration (12/12) and skin thickening (11/12) were also observed in these patients. Contrary to previous reports, skin changes and subareolar involvement were not rare occurrences in IGLM. In conclusion, the sonographic features of IGLM show irregular or tubular hypoechoic masses with minimal parenchymal distortion. Both clinical information and the description of radiographic features of IGLM may aid in the differentiation between IGLM and breast cancer, however histological confirmation is still required for the proper diagnosis and treatment of the disorder.

Allergic fungal rhinosinusitis is a benign and non-invasive sinusal disease related to a hypersensitivity reaction to fungal antigens. This process can cause tissue edema with chronic inflammatory disturbances of the respiratory mucosa. We present the case of a 17 year-old immunocompetent male, with history of seasonal allergic rhinosinusitis, nasal polyps and previous surgery for mucocele of the frontal sinus. Sticky material was removed in the last surgery that revealed pigmented and septed filaments on direct examination, and yielded Curvularia on Sabouraud dextrose agar. After a course of amphotericin B, treatment was switched to itraconazole, with good tolerance and favorable clinical outcome. Copyright © 2011. Published by Elsevier Espana.

A two years retrospective analysis of patients diagnosed as contact allergic dermatitis with positive patch test attending the Dermatology clinic was performed. Of the 346 patients with a positive patch test, 14% had occupational dermatitis. This condition affected mainly young and inexperienced workers. An inverse relationship was seen between age and prevalence of occupational allergic dermatitis. Allergic hand dermatitis was the commonest presentation in occupational allergic dermatitis. This was followed by dermatitis of the exposed skin (face, neck, hands and forearms). The common sensitising agents identified were rubber chemicals and nickel. The two main groups at risk were factory workers and medical personnel. The common allergens found in factory workers were epoxy resin, pewter, nickel and rubber chemicals. Exposure dermatitis occurred in patients working in the pewter industry. Two thirds of medical personnel with hand dermatitis were allergic to rubber gloves. One year follow up after patch testing showed that 19% of patients still suffered from chronic dermatitis. Dermatitis improved in 34% of patients. Forty-seven percent were cured and stopped attending the clinic after patch testing and adequate counselling.

Inhalation of indoor air pollutants may cause airway irritation and inflammation and is suspected to worsen allergic reactions. Inflammation may be due to mucosal damage, upper (sensory) and lower (pulmonary) airway irritation due to activation of the trigeminal and vagal nerves, respectively, and to neurogenic inflammation. The terpene, d-limonene, is used as a fragrance in numerous consumer products. When limonene reacts with the pulmonary irritant ozone, a complex mixture of gas and particle phase products is formed, which causes sensory irritation. This study investigated whether limonene, ozone or the reaction mixture can exacerbate allergic lung inflammation and whether airway irritation is enhanced in allergic BALB/cJ mice. Naïve and allergic (ovalbumin sensitized) mice were exposed via inhalation for three consecutive days to clean air, ozone, limonene or an ozone-limonene reaction mixture. Sensory and pulmonary irritation was investigated in addition to ovalbumin-specific antibodies, inflammatory cells, total protein and surfactant protein D in bronchoalveolar lavage fluid and hemeoxygenase-1 and cytokines in lung tissue. Overall, airway allergy was not exacerbated by any of the exposures. In contrast, it was found that limonene and the ozone-limonene reaction mixture reduced allergic inflammation possibly due to antioxidant properties. Ozone induced sensory irritation in both naïve and allergic mice. However, allergic but not naïve mice were protected from pulmonary irritation induced by ozone. This study showed that irritation responses might be modulated by airway allergy. However, aggravation of allergic symptoms was observed by neither exposure to ozone nor exposure to ozone-initiated limonene reaction products. In contrast, anti-inflammatory properties of the tested limonene-containing pollutants might attenuate airway allergy.

Coumarins from the roots of Angelica dahurica cause anti-allergic inflammation

Allergic inflammation is induced by allergens and leads to various allergic diseases, including rhinitis, asthma and conjunctivitis. Histamine is important in the pathogenesis of an immunoglobulin E-dependent allergic reaction and results in the secretion of cytokines associated with inflammation. Angelica dahurica (A. dahurica) is a medicinal plant widely used in China for the treatment of symptoms related to allergic inflammation. The present study investigated the chemical constituents from A. dahurica and evaluated their reductive effect on allergic inflammation. As a result, 15 compounds including 13 coumarins have been identified as isoimperatorin (1), imperatorin (2), oxypeucedanin (3), oxypeucedanin hydrate (4), bergapten (5), byakangelicin (6), phellopterin (7), byakangelicol (8), isopimpinellin (9), xanthotoxol (10), xanthotoxin (11), pimpinellin (12), scopoletin (13), β-sitosterol (14) and daucosterol (15). Compounds 1–13 were able to reduce the release of histamine, with compounds 4–6 exhibiting the most potent activity. Furthermore, compounds 1–12 were able to inhibit the secretion of tumor necrosis factor-α, interleukin (IL)-1β and IL-4, with compounds 5 and 7 exhibiting the strongest inhibitory effects. These compounds implemented the inhibitory effects on the expression of inflammatory cytokine genes through the inhibition of nuclear factor-κB activation. Virtual screening by a docking program indicated that compound 3 is a potent histamine H1 receptor antagonist. Additionally, the calculated physicochemical properties of these compounds support most furanocoumarins to be delivered to binding sites and permeate the cell membrane. The present findings contribute to understanding how A. dahurica attenuates allergic inflammation. PMID:28673013

To describe the proportion of patients allergic to β-lactam antibiotics and the prevalence of preoperative conjunctival bacteria among those undergoing cataract surgery in our area. Retrospective cross-sectional study of prevalence of β-lactam allergic patients consecutively scheduled for cataract surgery from 11 July 2005 to November 2012. For studying the prevalence of conjunctival bacteria and clinical characteristics in the patients' preoperative examination, those under 18 years and those with cataract surgery combined with other eye surgeries were excluded. Data from the first preoperative examination of the remaining patients were selected. Clinical data were extracted from the database generated in the evaluation made for anesthetic purposes, and the microbiological data from the laboratory database. Both bases were linked through a patient history code. A comparison was made between the prevalence of conjunctival bacteria and clinical characteristics in allergic and non-allergic patients. From 12,409 adults selected for the bacteriological study, 862 (6.96%) were allergic to β-lactams, their mean age (74.45 years) was higher than that of the non-allergic (P=.005). The proportion of women (71.4%) in the allergic patient group was much higher than that of men. The prevalence of pathogenic bacteria (especially Bacillus spp and Pseudomonas aeruginosa), lung disease and heart failure, was higher in allergic patients. The prevalence of allergy to β-lactams in this study is within the range described in other populations. The higher prevalence of pathogenic bacteria and the predominance of women in those allergic to β-lactams are useful data to guide their surgical prophylaxis.

Asthma is a heterogeneous chronic disease with different clinical expressions and responses to treatment. In recent years, several unbiased approaches based on clinical, physiological, and molecular features have described several phenotypes of asthma. Some phenotypes are allergic, but little is known about whether these phenotypes can be further subdivided. We aimed to phenotype patients with allergic asthma using an unbiased approach based on multivariate classification techniques (unsupervised hierarchical cluster analysis). From a total of 54 variables of 225 patients with well-characterized allergic asthma diagnosed following American Thoracic Society (ATS) recommendation, positive skin prick test to aeroallergens, and concordant symptoms, we finally selected 19 variables by multiple correspondence analyses. Then a cluster analysis was performed. Three groups were identified. Cluster 1 was constituted by patients with intermittent or mild persistent asthma, without family antecedents of atopy, asthma, or rhinitis. This group showed the lowest total IgE levels. Cluster 2 was constituted by patients with mild asthma with a family history of atopy, asthma, or rhinitis. Total IgE levels were intermediate. Cluster 3 included patients with moderate or severe persistent asthma that needed treatment with corticosteroids and long-acting β-agonists. This group showed the highest total IgE levels. We identified 3 phenotypes of allergic asthma in our population. Furthermore, we described 2 phenotypes of mild atopic asthma mainly differentiated by a family history of allergy.

Breastfeeding, Childhood Asthma, and Allergic Disease.

PubMed

Oddy, Wendy H

2017-01-01

The worldwide prevalence of childhood asthma has been increasing considerably, and the protection afforded by breastfeeding in its development has been the subject of controversy for more than 80 years. Previous systematic reviews have generally found a protective effect of breastfeeding on allergic outcomes, although many studies have methodological limitations. Although breastfeeding is protective against lower respiratory tract infection during infancy, such protection has not been demonstrated for asthma in all studies. Breastfeeding has health benefits for the mother and child. Exclusive breastfeeding for the first 6 months of an infant's life, with continued breastfeeding for up to 2 years or longer, is recognized as the "gold" standard for infant feeding because human milk is uniquely suited to the human infant, and its nutritional content and bioactivity promote a healthy development. There is increasing concern that the practice of delaying complementary foods until 6 months may exacerbate the risk of allergic disease. Breast milk contains immunological components that protect against infections and allergic disease in infancy. The composition of human breast milk is complex, containing factors that interact with the infant immune system and intestinal milieu including allergens, cytokines, immunoglobulins, polyunsaturated fatty acids, and chemokines. Transforming growth factor β is a cytokine in human milk involved in maintaining intestinal homeostasis, inflammation regulation, and oral tolerance development. Modern day society, with increased standards of hygiene, has changed the gut flora of Western infants, potentially impacting the risk of developing immune-mediated diseases including allergic disease and asthma. Microbial diversity is intrinsic to healthy immune maturation and function. Compared to breastfed infants, formula-fed infants had lower bacterial diversity and an altered intestinal microbiota in the first few weeks of life associated with

Chronic granulomatous disease: a review of the infectious and inflammatory complications

PubMed Central

2011-01-01

Chronic Granulomatous Disease is the most commonly encountered immunodeficiency involving the phagocyte, and is characterized by repeated infections with bacterial and fungal pathogens, as well as the formation of granulomas in tissue. The disease is the result of a disorder of the NADPH oxidase system, culminating in an inability of the phagocyte to generate superoxide, leading to the defective killing of pathogenic organisms. This can lead to infections with Staphylococcus aureus, Psedomonas species, Nocardia species, and fungi (such as Aspergillus species and Candida albicans). Involvement of vital or large organs can contribute to morbidity and/or mortality in the affected patients. Major advances have occurred in the diagnosis and treatment of this disease, with the potential for gene therapy or stem cell transplantation looming on the horizon. PMID:21624140

2007-01-01

Palisaded neutrophilic granulomatous dermatitis (PNGD) is a rare clinical entity of unknown cause. It often coexists with various autoimmune or immunoreactive systemic diseases, and thus it has been reported under multiple names. We describe a patient with quiescent ulcerative colitis, who presented with recurrent small tender papules, nodules and erythematous plaques, located mainly on her hands, together with finger swelling and polyarthralgia. The histopathologic picture indicated an early stage of PNGD with focal degeneration of collagen fibers but without distinct granuloma formation. The differentiation from neutrophilic dermatoses was necessary because of dense and diffuse infiltration of neutrophils with leukocytoclastic debris throughout the dermis, and the association of ulcerative colitis. Dapsone monotherapy was effective in improving the clinical symptoms. PNGD is only rarely associated with ulcerative colitis, and this case suggests that the concept of PNGD, especially in its early stages, might be considered in the wide spectrum of neutrophilic dermatoses.

Association between allergic and nonallergic rhinitis and obstructive sleep apnea.

PubMed

Zheng, Ming; Wang, Xiangdong; Zhang, Luo

2018-02-01

Allergic rhinitis and nonallergic rhinitis (NAR) are common disorders, which have been considered as potential risk factors for obstructive sleep apnea (OSA). This review summarizes the proposed underlying pathophysiological mechanisms to provide a better understanding of the relationship between these conditions. In adults, allergic rhinitis and NAR may be considered as symptoms potentiating, rather than risk potentiating factors in the pathophysiology of OSA, whereas in children, these are considered to be independent predictors for sleep-disordered breathing (SDB) and failure of adeno-tonsillectomy, the recommended first-line therapy for children with OSA. Current advances suggest IL-6 may be important in regulating the sleep-wake cycle, and serum soluble IL-6 receptor (sIL-6R) levels may reflect the severity of OSA. Elevated Th17/Treg ratio correlates positively with apnea-hypopnea index of OSA patients, and Th17 and Treg imbalances caused by allergic rhinitis and OSA, respectively, may possibly promote each other, leading to further imbalance. Moreover, obesity is a strong risk factor for OSA, and leptin plays an important role in ventilatory function and upper airway obstruction. The variant trigeminocardiac reflex and nasotrigeminal reflex may also be involved in the association between rhinitis and OSA. Allergic rhinitis/NAR and OSA are closely associated, and each condition can be detrimental to the other. Thus, clinicians should pay attention to the potential presence of allergic rhinitis/NAR in OSA patients and vice versa.

The awareness of primary immunodeficiency (PID) in Malaysia is still not forthcoming. Certain practical issues such as lack of clinical immunologists and specialized laboratory diagnostic facilities remain to be addressed. However, great efforts taken by passionate clinicians and scientists in the immunology networking have ascertained some prevalence. Despite the limitation, all suspected cases of PID are being properly investigated and competently managed. In this case report we highlighted the obstacles we faced in managing PID patients, particularly preparing for bone marrow transplant. This is the first transplanted case of chronic granulomatous disease in Malaysia, which emphasizes the importance of collaborative work to ensure further morbidities or mortalities are prevented.

Vimang is the brand name of formulations containing an extract of Mangifera indica L., ethnopharmacologically used in Cuba for the treatment of some immunopathological disorders, including bronchial asthma, atopic dermatitis and other allergic diseases. However, the effects of Vimang on allergic response have not been reported until now. In this study, the effects of Vimang and mangiferin, a C-glucosylxanthone isolated from the extract, on different parameters of allergic response are reported. Vimang and mangiferin showed a significant dose-dependent inhibition of IgE production in mice and anaphylaxis reaction in rats, histamine-induced vascular permeability and the histamine release induced by compound 48/80 from rat mast cells, and of lymphocyte proliferative response as evidence of the reduction of the amount of B and T lymphocytes able to contribute to allergic response. In these experiments, ketotifen, promethazine and disodium cromoglicate were used as reference drugs. Furthermore, we demonstrated that Vimang had an effect on an in-vivo model of inflammatory allergy mediated by mast cells. These results constitute the first report of the anti-allergic properties of Vimang on allergic models, as well as suggesting that this natural extract could be successfully used in the treatment of allergic disorders. Mangiferin, the major compound of Vimang, contributes to the anti-allergic effects of the extract.

Allergic rhinitis is a global illness with a well-recognised impact on quality of life and work performance. Comparatively little is known about the extent of its economic impact on society. The TOTALL study estimates the total cost of allergic rhinitis using a sample representing the entire Swedish population of working age. A questionnaire focused on allergic rhinitis was mailed out to a random population of Swedish residents, aged 18-65 years. Health-care contacts, medications, absenteeism (absence from work) and presenteeism (reduced working capacity at work) were assessed, and the direct and indirect costs of allergic rhinitis were calculated. Medication use was evaluated in relation to the ARIA guidelines. In all, 3,501 of 8,001 (44%) answered the questionnaire, and 855 (24%) of these reported allergic rhinitis. The mean annual direct and indirect costs because of allergic rhinitis were €210.3 and €750.8, respectively, resulting in a total cost of €961.1 per individual/year. Presenteeism represented 70% of the total cost. Antihistamines appear to be used in excess in relation to topical steroids, and the use of nasal decongestants was alarmingly high. The total cost of allergic rhinitis in Sweden, with a population of 9.5 million, was estimated at €1.3 billion annually. These unexpectedly high costs could be related to the high prevalence of disease, in combination with the previously often underestimated indirect costs. Improved adherence to guidelines might ease the economic burden on society.

Clinical characteristics of an allergic reaction to a polyether dental impression material.

PubMed

Rafael, Caroline Freitas; Liebermann, Anja

2017-04-01

Allergic and hypersensitivity reactions to dental impression materials may occur throughout dental treatment, with diverse manifestations from slight redness to severe pain and a burning mouth with total stomatitis. Patients are often unaware of these allergic reactions, which makes early identification of the cause almost impossible. In addition, symptoms usually begin after 24 hours and mostly in patients with a preexisting history of allergic responses. This report describes a patient with a suspected allergic reaction to a polyether dental impression material during prosthetic rehabilitation associated with a mandibular telescopic denture. Although instances of such occurrence are rare, clinicians need to be aware of these symptoms and select materials carefully for patients with a history of allergy.

2015-01-01

The prevalence of food allergy and other allergic diseases continues to rise within the industrialized world, yet the cause of this epidemic remains elusive. Environmental factors such as microbial exposures have more recently been implicated as one possible driving factor behind the increasing burden of allergic disease. The impact of gut microbiome on human development, nutritional needs, and disease has become evident with advances in our ability to study these complex communities of microorganisms, and there is a growing appreciation for the role of the microbiome in immune regulation. Several studies have examined associations between changes in the commensal microbiota and the development of asthma, allergic rhinitis, and asthma, but far less have evaluated the impact of the microbiome on the development of food allergy. In this article we review the human gastrointestinal microbiome, focusing on the theory and evidence for its role in the development of IgE-mediated food allergy and other allergic diseases.

Little is known about differential effects of antibiotic use on allergic diseases in rural versus urban environments. To examine whether area of residence in the first year of life modifies the relation between antibiotic use in early life and allergic diseases during childhood. Cross-sectional study of allergic diseases in 1517 children (ages 6-7 years) attending 101 schools in urban and rural areas of San Francisco (Córdoba, Argentina). Current asthma, wheeze, and allergic rhinoconjunctivitis were defined on the basis of responses to a validated questionnaire from the International Study of Asthma and Allergies in Childhood. Multivariate logistic regression was used for the analysis of antibiotic use and allergic diseases. After adjustment for paracetamol use, bronchiolitis, and other covariates, antibiotic use in the first year of life was associated with increased odds of current wheeze (odds ratio [OR], 1.8; 95% CI, 1.3-2.6) and allergic rhinoconjunctivitis (OR, 1.9; 95% CI, 1.3-2.7). After stratification by area of residence, antibiotic use was associated with current wheeze (OR, 2.4; 95% CI, 1.5-4.0) and allergic rhinoconjunctivitis (OR, 2.1; 95% CI, 1.3-3.4) among children who lived in an urban area in their first year of life, but not among those who lived in a rural area in their first year of life. Early-life antibiotic use is associated with current wheeze and allergic rhinoconjunctivitis in Argentinean children who lived in urban areas during their first year of life. Exposure to a rural environment early in life may protect against the adverse effects of antibiotics on atopic diseases in children. Copyright © 2017 American Academy of Allergy, Asthma & Immunology.

Strategies to prevent or reduce allergic disease.

Prescott, Susan; Nowak-Węgrzyn, Anna

2011-01-01

The need for allergy prevention strategies has never been greater. Surging rates of food allergy and eczema are now adding to the already substantial burden of asthma and respiratory allergic diseases. The parallel rise in many other immune diseases suggests that the developing immune system is highly vulnerable to modern environmental changes. These strong environmental pressures may be one reason why simple allergen avoidance strategies have not been successful. Another more recent strategy to curtail the allergy epidemic has been to identify factors associated with modern lifestyle that may be causally linked with allergic disease, in an attempt to restore more favourable conditions for immune tolerance during early development. More hygienic conditions and disruption of microbial exposure have prompted strategies to restore this balance using probiotic and prebiotic supplements. Modern dietary changes linked with allergic diseases have prompted supplementation studies to assess the preventive merits of specific immunomodulatory dietary nutrients such as polyunsaturated fatty acids. Other nutrients such as antioxidants, folate, and vitamin D are also currently under investigation. Modern environmental pollutants have also been associated with adverse effects on immune development and the risk of disease. While many of these avenues have provided some promise, they have not yet translated into specific recommendations. Current evidence-based guidelines for allergy prevention remain limited to avoidance of cigarette smoke, promotion of breastfeeding and the use of hydrolysed formula when breastfeeding is not possible. Allergen avoidance strategies have been largely removed from most guidelines. It is hoped that a number of ongoing studies will help provide clearer recommendations around the use of probiotics, prebiotics, specific dietary nutrients and the role of early introduction of allergenic foods for the promotion of tolerance.

We aim to describe the data collected from India during phase 3 of the International study of asthma and allergy in childhood (ISAAC) study. Prevalence, severity, and population characteristics associated with rhinitis, rhinoconjunctivitis, and eczema were assessed. Children from two age groups (6-7 and 13-14 years) were included in the study as per the ISAAC protocol. The symptoms of allergy and associated features were assessed using a questionnaire. The prevalence of allergic rhinitis among the 6-7 years age group was 11.3%, while it was 24.4% in the 13-14 years age group. The prevalence of allergic rhinoconjunctivitis was 3.9% in the 6-7 years age group and 10.9% in the 13-14 years age group. The prevalence of eczema was 2.8% in the 6-7 years age group and 3.7% in the 13-14 years age group. The passage of trucks near home, parental smoking, use of paracetamol, use of antibiotics, cooking with firewood, and television watching were associated with allergic rhinitis, rhinoconjunctivitis, and eczema. Maternal smoking was the strongest of all the associated features for allergic rhinitis, rhinoconjunctivitis, and eczema, especially in the 6-7 years age group (odds ratio: 1.9, 95% CI: 1.5-2.4; odds ratio: 2.9, 95% CI, 2.2-3.9; and odds ratio: 3.5, 95% CI: 2.6-4.8, respectively). Allergic conditions like allergic rhinitis, rhinoconjunctivitis, and eczema are prevalent among Indian children and are associated with environmental tobacco smoke, paracetamol use, antibiotic use, television watching, and outdoor and indoor air pollution. © 2016 John Wiley & Sons Ltd.

PubMed

Favrot, C; Rostaher, A; Fischer, N

2014-07-01

Allergies are often suspected in cats and they are mainly hypersensitivity reactions against insect bites, food- or environmental allergens. Cats, with non flea induced atopic dermatitis, normally present with one oft he following reaction patterns: miliary dermatitis, eosinophilic dermatitis, selfinduced alopecia or head and neck excoriations. None of these reaction patterns is nevertheless pathognomonic for allergic dermatitis, therefore the diagnosis is based on the one hand on the exclusion of similar diseases on the other hand on the successful response on a certain therapy. Recently a study on the clinical presentation of cats with non flea induced atopic dermatitis was published. In this study certain criteria for diagnosing atopy in cats were proposed. For therapy of allergic cats cyclosporin, glucocorticoids, antihistamines, hypoallergenic diets and allergen specific immunotherapy are used. This article should provide a recent overview on the clinical symptoms, diagnosis and therapy of feline allergic dermatitis.

Unproven diagnostic procedures in IgE-mediated allergic diseases.

Niggemann, B; Grüber, C

2004-08-01

A considerable body of literature on therapeutic aspects of complementary and alternative medicine has been published in recent years, but little is known on diagnostic procedures. This short review lists complementary and alternative diagnostic procedures for the diagnosis of allergic diseases and presents an assessment of their usefulness for the daily practice. The review of the literature revealed that neither the determination of specific immunoglobulin G-antibodies in serum, the hair-analysis, the cytotoxic test, kinesiology, iridology, or electrodermal testing represent useful tests for the daily practice. To date, no complementary or alternative diagnostic procedure can be recommended as a meaningful element in the diagnostic work-up of allergic diseases. This is especially true for food allergy: properly performed oral food challenges still represent the gold standard for implementing specific diets in food allergic individuals. Ineffective diagnostic approaches may be costly for the consumer and delay appropriate therapy.

A clinical decision support system for diagnosis of Allergic Rhinitis based on intradermal skin tests.

Allergic Rhinitis is a universal common disease, especially in populated cities and urban areas. Diagnosis and treatment of Allergic Rhinitis will improve the quality of life of allergic patients. Though skin tests remain the gold standard test for diagnosis of allergic disorders, clinical experts are required for accurate interpretation of test outcomes. This work presents a clinical decision support system (CDSS) to assist junior clinicians in the diagnosis of Allergic Rhinitis. Intradermal Skin tests were performed on patients who had plausible allergic symptoms. Based on patient׳s history, 40 clinically relevant allergens were tested. 872 patients who had allergic symptoms were considered for this study. The rule based classification approach and the clinical test results were used to develop and validate the CDSS. Clinical relevance of the CDSS was compared with the Score for Allergic Rhinitis (SFAR). Tests were conducted for junior clinicians to assess their diagnostic capability in the absence of an expert. The class based Association rule generation approach provides a concise set of rules that is further validated by clinical experts. The interpretations of the experts are considered as the gold standard. The CDSS diagnoses the presence or absence of rhinitis with an accuracy of 88.31%. The allergy specialist and the junior clinicians prefer the rule based approach for its comprehendible knowledge model. The Clinical Decision Support Systems with rule based classification approach assists junior doctors and clinicians in the diagnosis of Allergic Rhinitis to make reliable decisions based on the reports of intradermal skin tests.

Aspergillus spp are ubiquitous in the environment, and inhalation of Aspergillus spores is unavoidable. An intact immune system, with normal airway function, protects most people from disease. Globally, however, the toll from aspergillosis is high. The literature has largely focused on invasive aspergillosis, yet the burden in terms of chronicity and prevalence is higher for noninvasive Aspergillus conditions. This article discusses allergic aspergilloses and provides an update on the diagnosis and management of allergic bronchopulmonary aspergillosis, including in patients with cystic fibrosis, and an update on severe asthma with fungal sensitization. In addition, the presentation, investigation, and management of noninvasive infectious aspergilloses are reviewed. Copyright © 2017 Elsevier Inc. All rights reserved.

Antigen-Specific Induction of Osteopontin Contributes to the Chronification of Allergic Contact Dermatitis

Allergic contact dermatitis is a T cell-mediated immune response, which in its relapsing chronic form is of high socioeconomic impact. The phosphoglycoprotein osteopontin (OPN) has chemotactic and Th1 cytokine functions and in various models is essential for robust T cell-mediated immunity. Here we demonstrate that OPN is abundantly expressed by both effector T cells and keratinocytes in allergic contact dermatitis lesions. T cells from nickel-allergic donors secrete high levels of OPN following antigen-specific stimulation. OPN may substitute for missing IFN-γ secretion in T effector cells because low IFN-γ-producing T cell clones secrete high levels of OPN, and OPN down-modulates their interleukin-4 expression. Furthermore, interferon-γ from T effector cells augments OPN in allergic contact dermatitis by inducing OPN in keratinocytes, which in turn polarizes dendritic cells and attracts inflammatory cells. In the murine contact hypersensitivity (CHS) model for allergic contact dermatitis, OPN is strongly induced in antigen-specific proliferating T cells, and OPN null mice display a reduced chronic CHS inflammatory response due to a decreased influx of effector T cells. Importantly, because of its function for chronic allergic contact dermatitis, OPN may well be a therapeutic target, because anti-OPN antibody treatment in part suppresses established chronic CHS.

As the prevalence of allergic disease dramatically rises worldwide, prevention strategies are increasingly being considered. Given the potential modulatory effect of nutritional factors on disease, altering maternal diet during pregnancy and/or lactation has been considered in preventing allergic disease in offspring. Although there are a number of observational studies that have examined possible associations between maternal diet and allergic outcomes in offspring, interventional trials are limited. Furthermore, there is a paucity of studies that have prospectively studied maternal dietary intake as well as measuring maternal and infant biologic samples (blood, urine, breast milk) and their relation to allergic outcomes in infants. There is also a particular need to define terminology such as 'fruit and vegetables intake', 'healthy diet', and 'diet diversity' in order to make studies comparable. In this review, we discuss current evidence of maternal dietary factors during pregnancy and/or lactation that may play a role in the offspring developing allergic disease, including factors such as overall dietary intake patterns, specific whole food consumption (fish, fruit and vegetables, and common allergic foods), and individual immunomodulatory nutrient intakes. Additionally, we discuss the limitations of previous studies and propose improvements to study design for future investigation. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

A 13-year-old girl with an osteosarcoma was treated by surgery and chemotherapy. During three transfusions of apheresis platelet concentrates allergic reactions occurred, partly in spite of premedication with an antihistamine and a corticoid. As the patient declared to be allergic to some foods, in-vitro tests for allergen-specific IgE antibodies were performed and showed markedly positive results for specific IgE to carrot and celery, less so to hazelnut, peanut and a lot of other food antigens. The donor of one of the unsuitable platelet concentrates remembered when questioned, that he had eaten carrots and chocolate with hazelnuts during the evening before platelet donation. Two washed platelet concentrates were transfused without any problem. Furthermore, transfusions of nine red blood cell concentrates and one unit of virus-inactivated frozen pooled plasma were well tolerated. Patients should be asked for allergies previous to transfusions to be alert to allergic reactions in patients with a positive history of food or drug allergies. If premedication with antihistamines does not prevent severe allergic transfusion reactions, transfusion of washed platelet concentrates and of virus-inactivated frozen pooled plasma can be considered. © Georg Thieme Verlag KG Stuttgart · New York.

Propolis, Colophony, and Fragrance Cross-Reactivity and Allergic Contact Dermatitis.

2016-01-01

Colophony and propolis are among the complex plant resins used in a wide variety of medicinal and personal care products. A number of studies of colophony, propolis, and fragrance mixes suggest that contact with one of these allergens may increase the risk of delayed-type hypersensitivity reactions with additional compounds of significant cross-reactivity. The aims of this study were to determine rates of cross-reactivity between propolis, colophony, and different fragrance mixes and to determine significant cross-reactivity thresholds for which to counsel patient avoidance. Rates of cross-reactivity were calculated from the databases of 2 midwestern US patch testing centers. Rates were calculated both separately and collectively. For patients allergic to colophony, fragrance and propolis may be considered significant cross-reactors. For patients allergic to propolis, fragrance and colophony may be considered significant cross-reactors. Cross-reactions between colophony, propolis, and fragrance mixes are unidirectional so, for patients allergic to fragrance, cross-reaction to propolis or colophony is not significant. Colophony allergy is found in only a small number of fragrance-allergic patients and is not a good indicator for fragrance allergy.

Allergic diseases such as atopic dermatitis, rhinitis, asthma, and anaphylaxis are attractive research areas. Tyrosol (2-(4-hydroxyphenyl)ethanol) is a polyphenolic compound with diverse biological activities. In this study, we investigated whether tyrosol has anti-allergic inflammatory effects. Ovalbumin-induced active systemic anaphylaxis and immunoglobulin E-mediated passive cutaneous anaphylaxis models were used for the immediate-type allergic responses. Oral administration of tyrosol reduced the allergic symptoms of hypothermia and pigmentation in both animal models. Mast cells that secrete allergic mediators are key regulators on allergic inflammation. Tyrosol dose-dependently decreased mast cell degranulation and expression of inflammatory cytokines. Intracellular calcium levels and activation of inhibitor of κB kinase (IKK) regulate cytokine expression and degranulation. Tyrosol blocked calcium influx and phosphorylation of the IKK complex. To define the molecular target for tyrosol, various signaling proteins involved in mast cell activation such as Lyn, Syk, phosphoinositide 3-kinase (PI3K), and Akt were examined. Our results showed that PI3K could be a molecular target for tyrosol in mast cells. Taken together, these findings indicated that tyrosol has anti-allergic inflammatory effects by inhibiting the degranulation of mast cells and expression of inflammatory cytokines; these effects are mediated via PI3K. Therefore, we expect tyrosol become a potential therapeutic candidate for allergic inflammatory disorders.

A series of 18 allergic cats with multifocal Malassezia spp. overgrowth is reported: atopic dermatitis was diagnosed in 16, an adverse food reaction in another and one was euthanized 2 months after diagnosis of Malassezia overgrowth. All the cats were otherwise healthy and those tested (16 out of 18) for feline leukaemia or feline immunodeficiency virus infections were all negative. At dermatological examination, multifocal alopecia, erythema, crusting and greasy adherent brownish scales were variably distributed on all cats. Cytological examination revealed Malassezia spp. overgrowth with/without bacterial infection in facial skin (n = 11), ventral neck (n = 6), abdomen (n = 6), ear canal (n = 4), chin (n = 2), ear pinnae (n = 2), interdigital (n = 1) and claw folds skin (n = 1). Moreover, in two cats Malassezia pachydermatis was isolated in fungal cultures from lesional skin. Azoles therapy alone was prescribed in seven, azoles and antibacterial therapy in eight and azoles with both antibacterial and anti-inflammatory therapy in three of the cats. After 3-4 weeks of treatment, substantial reduction of pruritus and skin lesions was observed in all 11 cats treated with a combined therapy and in five of seven treated solely with azoles. Malassezia spp. overgrowth may represent a secondary cutaneous problem in allergic cats particularly in those presented for dermatological examination displaying greasy adherent brownish scales. The favourable response to treatment with antifungal treatments alone suggests that, as in dogs, Malassezia spp. may be partly responsible for both pruritus and cutaneous lesions in allergic cats.

In this study, we assessed the effect of endonasal phototherapy on quality of life, nasal obstruction and the other symptoms in allergic rhinitis with visual analog scale (VAS), sinonasal outcome test-20 (SNOT-20), and acoustic rhinometry. Twenty-four patients (6 males, 18 females; mean age 41.3±13.0 years; range 20 to 60 years) suffering allergic rhinitis refractory to anti allergic drugs for at least two years were enrolled in the study. Each patient underwent a total of six sessions of endonasal phototherapy with Rhinolight (Rhinolight Ltd, Szeged, Hungary) performed three times a week for two weeks. During course of the investigation, additional therapy was not applied to any of the patients. Before and one month after treatment, patients completed visual analog scale and SNOT-20 forms and nasal obstruction was evaluated with acoustic rhinometry. After the treatment, the mean VAS score and the mean total SNOT-20 score were found lower than the results before the therapy (p=0.0001, p=0.0001). A significant decrease was found in the scores of sneezing, nasal discharge, postnasal drainage, coughing after treatment (p=0.0001). During objective evaluation of nasal obstruction with acoustic rhinometry, no statistically significant difference was found between pre- and post-treatment findings. Endonasal phototherapy is an effective modality in the treatment of symptomatology in allergic rhinitis patients refractory to antiallergic drugs. It is detected that endonasal phototherapy has positive effects on the quality of life. However, no effect on nasal obstruction was found with acoustic rhinometry which is an objective method.

Taking medical history, physical examination, and performing some in vivo and in vitro tests are necessary for the diagnosis of allergy. Skin prick test (SPT) is considered as the standard method and first-line approach for the detection of allergic sensitization. Although mainly SPT is used for the detection of allergic sensitization, intradermal skin test (IDST) may be necessary, especially in patients with a negative SPT result. IDST is quite safe; however, is nowadays seldom used for detection of inhalant allergy and its value remains controversial. We aimed to investigate whether IDST is useful and necessary in diagnosis of respiratory allergies or not. This study involved 4223 patients with allergic rhinitis (AR) and/or bronchial asthma (BA). SPT results were positive in 2419 patients (57%) and negative in 1804 (43%). IDST was applied to 344 patients with marked allergic symptoms and with negative SPT results. Out of 344 patients, 152 (44%) showed allergic sensitization to IDST. The most commonly encountered allergic response was against the house dust mite (HDM) (32.6%). Allergic response against fungal spores was also relatively high (22%), while the pollen allergy rate (4.3%) was quite low. In BA patients with negative prick test, IDST made a significant contribution to the diagnosis of HDM allergy (p=0.003). To avoid missed diagnosis of AR and BA, particularly regarding  the HDM allergy, application of IDST may be beneficial; therefore, IDST should be considered as the next step after SPT for diagnosis of allergy prior to in vitro or provocation tests.

Safety of meropenem in patients reporting penicillin allergy: lack of allergic cross reactions.

Cunha, B A; Hamid, N S; Krol, V; Eisenstein, L

2008-04-01

Over the years, meropenem has become the mainstay of empiric therapy for serious systemic infections in critically ill patients. Although we have had extensive clinical experience since 1996 using meropenem safely in treating hundreds of patients with reported allergic reactions to penicillin without any adverse events, we have not published our experience. This study was conducted to document our clinical practice experience. Accordingly, over a 12-month period we prospectively monitored 110 patients treated with meropenem reporting penicillin allergic reactions for that 12-month period. Since early empiric therapy in such patients is essential, there is often no time for penicillin skin testing. Penicillin skin testing was not done in this "real world" clinical study. Patients were divided into two groups, depending on the nature of their penicillin allergic reactions. During a 12-month period, 110 patients with non-anaphylactic (59) and anaphylactic (51) penicillin allergic reactions tolerated prolonged meropenem therapy (1-4 weeks) safely without any allergic reactions. Based on these data and our previous clinical experience, there appears to be little/no potential cross reactivity between meropenem and penicillins even in patients with a definite history of anaphylactic reactions to penicillins. To the best of our knowledge, this is the first prospective clinical study demonstrating that meropenem may be safely given to patients with known/unknown allergic reactions to penicillin, including those with anaphylactic reactions, without penicillin skin testing. We conclude that meropenem may be given safely to patients reporting a history of non-anaphylactic or anaphylactic allergic reactions to penicillins without penicillin skin testing.

Cockroach protease allergen induces allergic airway inflammation via epithelial cell activation

2017-01-01

Protease allergens are known to enhance allergic inflammation but their exact role in initiation of allergic reactions at mucosal surfaces still remains elusive. This study was aimed at deciphering the role of serine protease activity of Per a 10, a major cockroach allergen in initiation of allergic inflammation at mucosal surfaces. We demonstrate that Per a 10 increases epithelial permeability by disruption of tight junction proteins, ZO-1 and occludin, and enhances the migration of Monocyte derived dendritic cell precursors towards epithelial layer as exhibited by trans-well studies. Per a 10 exposure also leads to secretion of IL-33, TSLP and intracellular Ca2+ dependent increase in ATP levels. Further, in vivo experiments revealed that Per a 10 administration in mice elevated allergic inflammatory parameters along with high levels of IL-33, TSLP, IL-1α and uric acid in the mice lungs. We next demonstrated that Per a 10 cleaves CD23 (low affinity IgE receptor) from the surface of PBMCs and purified B cells and CD25 (IL-2 receptor) from the surface of PBMCs and purified T cells in an activity dependent manner, which might favour Th2 responses. In conclusion, protease activity of Per a 10 plays a significant role in initiation of allergic airway inflammation at the mucosal surfaces. PMID:28198394

Thiamazole is the most used antithyroid drug for thyrotoxicosis in Basedow-Graves' (BG) (autoimmune) disease and in toxic multinodular goitre (TMG) (non-autoimmune). This study aims to find whether allergic reactions to thiamazole occur more frequently during the treatment of BG than of TMG. Retrospective study, of 128 patients newly diagnosed and treated for thyrotoxicosis in the first 6 months of 2006, in the Endocrinology Department of "Elias" Hospital, Bucharest. Cases were all patients treated with thiamazole who developed allergic reactions. Controls were all patients treated with thiamazole without allergic reactions. Risk factor was considered to be the presence of BG. Cases group consisted of 6 patients. All 6 started treatment with thiamazole for BG, and developed allergic reactions after 2-4 weeks of treatment. When thiamazole was withdrawn, allergic symptoms ceased under antihistamines and steroids. In order to control the thyrotoxicosis, antihistamines and oral steroids was administered, together with thiamazole in slow increasing doses. After about 4 weeks under this combination, a tolerance to thiamazole seems to appear. Control group consisted of 122 patients who started thiamazole: 66 for BG and 56 for TMG (without allergic reactions). Allergy to thiamazole was significantly associated with the autoimmune BG, and not with TMG (p = 0.03, OR = 11.04). None of the patients with TMG developed allergic reactions to the drug. Tolerance to this drug may occur.

This review summarizes recent findings on mast cell biology with a focus on IgE-independent roles of mast cells in regulating allergic responses. Recent studies have described novel mast cell-derived molecules, both secreted and membrane-bound, that facilitate cross-talk with a variety of immune effector cells to mediate type 2 inflammatory responses. Mast cells are complex and dynamic cells that are persistent in allergy and are capable of providing signals that lead to the initiation and persistence of allergic mechanisms.

Idiopathic granulomatous mastitis (IGM) is a rare and chronic inflammatory disorder. IGM mimics breast cancer regarding its clinical and radiological features. Etiology of IGM remains unclarified. Our patient was 37-year-old and 14 weeks pregnant. There was pain, redness and swelling in the right breast. The mass suggestive of malignancy was detected in sonography. Serum CA 125 and CA 15-3 levels were high. Genetic analysis was performed for the etiology. methylenetetrahydrofolate reductase (MTHFR) C 677 TT, β-fibrinogen-455 G>A, plasminogen activator inhibitor (PAI)-1 5 G/5 G, angiotensin-converting enzyme (ACE) I/D mutation was found. IGM was diagnosed by cor biopsy. An association was also reported between breast cancer and mutations in MTHFR-C 677 T, PAI-1, ACE genes. Genetic polymorphisms may involve in the development of IGM as it was seen in our case. Further studies should be conducted to better clarify this plausible association. PMID:27619324

Inverse association between allergic conditions and glioma risk has been consistently reported in epidemiological studies with little attention paid to potential environmental confounders; the association with meningioma risk is less consistent. We examined the association between allergy history and risk of glioma and meningioma in adults using data from the CERENAT (CEREbral tumors: a NATional study) multicenter case-control study carried out in 4 areas in France in 2004-2010. Participants' histories of doctor-diagnosed allergic asthma, eczema, rhinitis/hay fever and other allergic conditions were collected at onset through a detailed questionnaire delivered in a face-to-face interview. Conditional logistic regression for matched sets was adjusted for participants' educational level and mobile phone use. A total of 273 glioma cases, 218 meningioma cases and 982 matched controls selected from the local electoral rolls were analyzed. A significant inverse association was found between glioma and a history of any allergy (OR 0.52, 95% CI 0.36-0.75), with a dose-effect relationship with the number of allergic conditions reported (p-trend = 0.001) and a particularly strong association with hay fever/allergic rhinitis (OR 0.46, 95% CI 0.30-0.72). Interestingly, associations with glioma risk were more pronounced in women. For meningioma, no association was observed with overall or specific allergic conditions. Our findings confirmed the inverse association between allergic conditions and glioma risk but questioned the role of allergy in meningioma risk. Future research is needed to clarify the biological mechanism of overall allergy and allergic rhinitis on glioma and to confirm the different effect by gender.

Skin testing is a reliable and safe way to diagnose IgE-mediated allergies, with rare side-effects. Two cases of systemic allergic reactions during skin testing to food allergens are hereby reported. A 28-year-old male reported allergic reactions, mild to moderate in severity, each time he tasted fish in the frame of his professional duties. During SPT and prick-to-prick to raw and cooked fishes, he presented urticaria and tachycardia. A 59-year-old male had a long history of urticaria-angioedema and asthma attacks, following the consumption of mammalian meat. He was skin-tested to various meats and during the 5 last minutes of the test he developed generalized urticaria, allergic rhinitis and conjunctivitis. They were both advised to completely avoid the relative allergens. In conclusion, skin testing, particularly prick-to-prick, may cause anaphylaxis. Tests should be performed only by physicians with proper training in allergy, experienced in treating promptly and properly episodes of anaphylaxis.

Purpose Despite links between maternal and child health status, evidence on the association between gum infection in pregnant mothers and childhood allergies is scarce. We aim to evaluate the risk of developing allergy in children born to periodontal mothers in a nationwide study. Methods We conducted a 9-year population-based, retrospective cohort study using Taiwan’s National Health Insurance database. A study cohort of 42,217 newborns born to mothers with periodontal disease during pregnancy was identified in 2001 and matched with 42,334 babies born to mothers without any infection (control) by mother’s age at delivery and baby sex. With a follow-up period from 2001 to 2010, we observed the incidence of allergic rhinitis (AR), allergic conjunctivitis (AC), and eczema in these children. Cox proportional hazards regression models were performed with premature deaths as competing risk for the estimation of allergic disease risks. Results Nine-year cumulative incidences were the highest among children born to periodontal mothers; they reached 46.8%, 24.2%, and 40.4% (vs. 39.5%, 18.3% and 34.8% in control) for AR, AC, and eczema, respectively. Our results showed moderately increased risks for the allergies in children born to periodontal mothers relative to their matched non-inflammatory control (adjusted HRs: 1.17, 95% CI: 1.15–1.20; 1.27, 1.24–1.31; 1.14, 1.12–1.17, respectively). Because the impact of food consumption and living environment cannot be considered using insurance data, we attempted to control it by adjusting for parental income and mother’s residential area. Conclusions Overall cumulative incidence and risks of children born to periodontal mothers for AR, AC, and eczema are significantly higher than those born to non-inflammatory mothers. Gum infection in women during pregnancy is an independent risk factor for allergic diseases in children, thus its intergenerational consequences should be considered in gestational care.

Skin is a major target organ for allergic reactions to small molecular weight compounds. Drug allergic reactions may be life-threatening such as in the case of anaphylactic reactions or bullous drug reactions and occur in about 5% of all hospitalized patients. Allergic contact dermatitis has an enormous influence on the social life of the patient because it is the most frequent reason for occupational skin diseases and the treatment and prevention of this disease cost approximately Euro 3 billion per year in Germany. The different proposed pathophysiological pathways leading to a drug eruption are discussed in this paper. All majormore » enzymes which are involved in the metabolism of xenobiotica were shown to be present in skin. Evidence supporting the role of metabolism in the development of drug allergy and allergic contact dermatitis is demonstrated in the example of sulphonamides and fragrances.« less

Background: Skin prick test (SPT) is the most effective diagnostic test to detect IgE mediated type I allergic reactions like allergic rhinitis, atopic asthma, acute urticaria, food allergy etc. SPTs are done to know allergic sensitivity and applied for devising immunotherapy as the therapeutic modality. Materials and Methods: This prospective study was conducted in the department of Immunology and Molecular medicine at SKIMS. A total of 400 patients suffering from allergic rhinitis, asthma and urticaria were recruited in this study. SPT was performed with panel of allergens including house dust mite, pollens, fungi, dusts, cockroach, sheep wool and dog epithelia. Allergen immunotherapy was given to allergic rhinitis and asthmatic patients as therapeutic modality. Results: In our study, age of patients ranged from 6 to 65 years. Majority of patients were in the age group of 20-30 years (72%) with Male to female ratio of 1:1.5. Of the 400 patients, 248 (62%) had urticaria, 108 (27%) patients had allergic rhinitis and 44 (11%) patients had asthma. SPT reaction was positive in 38 (86.4%) with allergic asthma, 74 (68.5%) patients with allergic rhinitis and 4 (1.6%) patient with urticaria, respectively. Allergen immunotherapy was effective in 58% patients with allergic rhinitis and 42% allergic asthma. Conclusion: Identifiable aeroallergen could be detected in 86.4% allergic asthma and 68.5% allergic rhinitis patients by SPT alone. Pollens were the most prevalent causative allergen. There was significant relief in the severity of symptoms, medication intake with the help of allergen immunotherapy. PMID:23372205

Airway inflammation is key to the severity and persistence of asthma. Recent studies have revealed novel immune mechanisms that target dendritic cells, T helper 2 cytokines, regulatory T cells, and type 2 innate lymphoid cells in allergic inflammation, as well as novel approaches that target airway smooth muscle in asthma. These advances inform the development of new targeted treatments for allergic inflammation and asthma with the potential to provide therapeutic benefit.

Study of frequency of allergic rhinitis in selected regions of Poland in cities and countryside. 8913 respondents, from Warszawa, Katowice, Lublin and Zamojszczyzna (countryside), answered a questionnaire based on ECRHS II and ISAAC. The respondents were drawn from PESEL ID numbers. They were divided into three groups: 6-7 years, 13-14 and 20-44 years, both sexes. 21-23% adults living in the city and 12% living in the countryside confirmed some type of sensitization, including allergic catarrh. In children the same symptoms are more frequent and reported in 23-27% of those living in city and 17% of those living in the countryside. Sneezing, running or obstructed nose not related to cold, fever or flu were reported by 22% of the adults living in Zamojszczyzna and 33-42% of those living in the cities. The symptoms are reported in 20% children living in the countryside and 29-39% of those living in the cities. All of results are statistical significant. Study of frequency of allergic rhinitis in selected regions of Poland shows that results are similar with analysis on the world. Connection between urban development and occurrence of allergic rhinitis was confirmed. Allergic rhinitis is more frequently in group of people living in cities than people living on countryside. Probably allergic rhinitis is not integrally examined in adults group.

The current study characterizes the mechanism by which the aqueous extract of Lycopus lucidus Turcz. (Labiatae) (LAE) decreases mast cell-mediated immediate-type allergic reaction. The immediate-type allergic reaction is involved in many allergic diseases such as asthma and allergic rhinitis. LAE has been used as a traditional medicine in Korea and is known to have an anti-inflammatory effect. However, its specific mechanism of action is still unknown. LAE was anally administered to mice for high and fast absorption. LAE inhibited compound 48/80-induced systemic reactions in mice. LAE decreased the local allergic reaction, passive cutaneous anaphylaxis, activated by anti-dinitrophenyl (DNP) IgE antibody.more » LAE dose-dependently reduced histamine release from rat peritoneal mast cells activated by compound 48/80 or anti-DNP IgE. Furthermore, LAE decreased the secretion of TNF-{alpha} and IL-6 in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187-stimulated human mast cells. The inhibitory effect of LAE on the pro-inflammatory cytokine was p38 mitogen-activated protein kinase (MAPK) and nuclear factor-{kappa}B (NF-{kappa}B) dependent. LAE attenuated PMA plus A23187-induced degradation of I{kappa}B{alpha} and nuclear translocation of NF-{kappa}B, and specifically blocked activation of p38 MAPK, but not that of c-jun N-terminal kinase and extracellular signal-regulated kinase. Our findings provide evidence that LAE inhibits mast cell-derived immediate-type allergic reactions and involvement of pro-inflammatory cytokines, p38 MAPK, and NF-{kappa}B in these effects.« less

Protease-activated receptor 2 (PAR-2) is a G protein-coupled receptor possibly involved in the pathogenesis of asthma. PAR-2 also modulates ion transport in cultured epithelial cells, but these effects in native airways are controversial. The influence of allergic inflammation on PAR-2-induced changes in ion transport has received little attention. Here, we studied immediate changes in transepithelial short circuit current (I (sc)) induced by PAR-2 activation in the tracheas of naive and allergic mice. Activation of PAR-2 with an apically added activation peptide (AP) induced a small increase in I (sc), while a much larger increase was observed following basolateral AP addition. In ovalbumin-sensitized and -challenged animals used as a model of allergic airway inflammation, the effect of basolateral AP addition was enhanced. Responses to basolateral AP in both naive and allergic mice were not decreased by blocking sodium absorption with amiloride or CFTR function with CFTR(inh)172 but were reduced by the cyclooxygenase inhibitor indomethacin and largely blocked (>80%) by niflumic acid, a calcium-activated chloride channels' (CaCC) blocker. Allergic mice also showed an enhanced response to ATP and thapsigargin. There was no change in mRNA expression of Par-2 or of the chloride channels Ano1 (Tmem16a) and Bestrophin 2 in tracheas from allergic mice, while mRNA levels of Bestrophin 1 were increased. In conclusion, basolateral PAR-2 activation in the mouse airways led to increased anion secretion through apical CaCC, which was more pronounced in allergic animals. This could be a protective mechanism aimed at clearing allergens and defending against mucus plugging.

Allergic conjunctivitis is a common problem that significantly impairs patients’ quality of life. Whether air pollution serves as a risk factor for the development of allergic conjunctivitis remains elusive. In this paper, we assess the relationship between air pollutants and weather conditions with outpatient visits for allergic conjunctivitis. By using a time-series analysis based on the largest dataset ever assembled to date, we found that the number of outpatient visits for allergic conjunctivitis was significantly correlated with the levels of NO2, O3, and temperature, while its association with humidity was statistically marginal. No associations between PM10, PM2.5, SO2, or wind velocity and outpatient visits were seen. Subgroup analyses showed that sex seemed to modify the effects of humidity on outpatient visits for allergic conjunctivitis, but not for NO2, O3, or temperature. People younger than 40 were found to be susceptible to changes of all four parameters, while those older than 40 were only consistently affected by NO2 levels. Our findings revealed that higher levels of ambient NO2, O3, and temperature increase the chances of outpatient visits for allergic conjunctivitis. Ambient air pollution and weather changes may contribute to the worsening of allergic conjunctivitis.

Allergic rhinitis (AR) is especially prevalent among the population of large cities. Immunologically, the airway epithelium is a region where the population of allergen-presenting cells concentrates. These cells actively express a group of receptors of the innate immune system. A specific cytokine profile is its representation. The study was aimed at evaluating the cytokine profile in patients with seasonal and perennial allergic rhinitis. The cytokine profile of nasal secretion and blood serum of 44 patients with AR was studied. 24 of them had seasonal allergic rhinitis (SAR), and 20 patients suffered from perennial allergic rhinitis (PAR). The patients' age ranged from 4 to 60 years. It was determined in our study that the activation of the GM-CSF production retained in patients with PAR sensitized to mite allergen components ( Dermatophagoides pteronyssinus ). There was a higher production profile of TNF- α and TSLP in nasal secretion in the patients with perennial allergic rhinitis and additional high sensitization to SEs. Sensitization to mold fungal allergen components significantly increases in patients with seasonal allergic rhinitis. They demonstrated high level of sensitization to the Aspergillus fumigatus component m3. Thus, along with other clinical trials, the study performed would clarify some aspects of molecular pathogenesis of human allergic rhinitis.

The prevalence of allergic rhinitis and the social burden related to the management of allergic rhinitis have persistently increased. There are many studies investigating the association between the allergic diseases of children and the stress of their parent. However, the relationship between parenting stress and the incidence of allergic rhinitis among children requires further investigation. We aimed to investigate the significance of parenting stress for mothers with children treated for allergic rhinitis. The mothers of 250 children in the second and third grade of elementary school were involved in this study. The Parenting Stress Index-Short Form (PSI-SF) was used to measure parenting stress. Additionally, the monthly household income, treatment history for allergic diseases (atopic dermatitis, asthma, and allergic rhinitis) during the past 12 months, and maternal education status were investigated using the questionnaire. Parenting stress index score was significantly higher among the mothers of children treated for allergic rhinitis (76.41 ± 9.35) compared with the parents of children without treatment history for allergic rhinitis (70.06 ± 13.74). Nonetheless, there were no significant differences between the cases of children with atopic dermatitis and those with asthma. We analyzed the association between allergic rhinitis and parenting stress adjusted for the monthly household income, and maternal education status, and showed that a treatment history of allergic rhinitis was significantly associated with parenting stress (coefficient 7.477, 95% interval 1.703-13.252; p = 0.011). Treatment of the children for allergic rhinitis significantly affects the parenting stress of their mother. We recommend that mothers with children with allergic rhinitis should receive appropriate counseling about parenting stress. Copyright © 2017 Elsevier B.V. All rights reserved.

Based on two clinical observations of adverse reactions during exercise with latex sport bands, we aimed to assess the possible risk for allergic patients posed by this equipment by investigating allergen content and IgE binding potential. Protein extracts of three different latex sport bands were characterized with sera of latex allergic patients. The IgE recognition profile of the allergic patients was identified by component resolved diagnosis and the allergen composition of the extracts was characterized by inhibition assays with the recombinant latex allergens Hev b 1, 3, 5, 6.02, and 8. The sera showed pronounced IgE binding to all three blotted extracts, however with diverse patterns. Inhibition assays revealed the presence of Hev b 1, 3, 5, and 8 in latex sport band extracts. The clinical relevance of contained allergens was demonstrated by strong skin reactions when testing with latex sport bands. From our results we conclude that latex sport bands contain clinically relevant allergens and may cause latex allergic individuals to experience allergic symptoms, potentially amplified by exercise-induced mechanisms. Even though latex is labeled on products, it is important that patients as well as athletic trainers and physical therapists recognize the risk of adverse reactions with these bands.

External exposome and allergic respiratory and skin diseases.

Allergies are complex diseases that result from interactions between multiple genetic and environmental factors. However, the increase in allergies observed in the past decades is explained exclusively by environmental changes occurring in the same period. Presently, the exposome, the totality of specific and nonspecific external environmental exposures (external exposome) to which a subject is exposed from preconception onward and their consequences at the organ and cell levels (internal exposome), is being considered to explain the inception, development, and exacerbations of allergic diseases. Among the best-studied environmental factors of the specific external exposome, indoor and outdoor aeroallergens and air pollutants play a key role in the etiopathogenesis of the inflammatory response to allergens and in clinical manifestations of allergic disease. Climate change, urbanization, and loss of biodiversity affect sources, emissions, and concentrations of main aeroallergens and air pollutants and are among the most critical challenges facing the health and quality of life of the still increasing number of allergic patients today and in the coming decades. Thunderstorm-related asthma is a dramatic example of the effects of combined environmental factors and an in vivo model for understanding the mechanisms at work in respiratory allergy. Environment- or lifestyle-driven aberrancies in the gut and skin microbiome composition represent key mediators of allergic diseases. A better knowledge of the effect of the external exposome on allergy development is crucial for urging patients, health professionals, and policymakers to take actions to mitigate the effect of environmental changes and to adapt to them.

Introduction Utility of various dental materials ranging from diagnosis to rehabilitation for the management of oral diseases are not devoid of posing a potential risk of inducing allergic reactions to the patient, technician and dentist. This review aims to develop a systematic approach for the selection and monitoring of dental materials available in the market thereby giving an insight to predict their risk of inducing allergic reactions. Materials and Methods Our data included 71 relevant articles which included 60 case reports, 8 prospective studies and 3 retrospective studies. The source of these articles was Pub Med search done with the following terms: allergies to impression materials, sodium hypochlorite, Ledermix paste, zinc oxide eugenol, formaldehyde, Latex gloves, Methyl methacrylate, fissure sealant, composites, mercury, Nickel-chromium, Titanium, polishing paste and local anaesthesia. All the relevant articles and their references were analysed. The clinical manifestations of allergy to different dental materials based on different case reports were reviewed. Results After reviewing the literature, we found that the dental material reported to cause most adverse reactions in patients is amalgam and the incidence of oral lichenoid reactions adjacent to amalgam restorations occur more often than other dental materials. Conclusion The most common allergic reactions in dental staff are allergies to latex, acrylates and formaldehyde. While polymethylmethacrylates and latex trigger delayed hypersensitivity reactions, sodium metabisulphite and nickel cause immediate reactions. Over the last few years, due to the rise in number of patients with allergies from different materials, the practicing dentists should have knowledge about documented allergies to known materials and thus avoid such allergic manifestations in the dental clinic.

Concealing emotions at work can cause considerable psychological stress. While there is extensive research on the adverse health effects of concealing emotions and the association between allergic diseases and stress, research has not yet investigated whether concealing emotions at work is associated with allergic rhinitis. Allergic rhinitis is a common disease in many industrialized countries, and its prevalence is increasing. Thus, our aim was to determine the strength of this association using data from three years (2007-2009) of the 4th Korean National Health and Nutrition Examination Survey. Participants (aged 20-64) were 8,345 individuals who were economically active and who had completed the questionnaire items on concealing emotions at work. Odds ratio (OR) and 95% confidence intervals (95% CIs) were calculated for allergic rhinitis using logistic regression models. Among all participants, 3,140 subjects (37.6%) reported concealing their emotions at work: 1,661 men and 1,479 women. The OR (95% CIs) for allergic rhinitis among those who concealed emotions at work versus those who did not was 1.318 (1.148-1.512). Stratified by sex, the OR (95% CIs) was 1.307 (1.078-1.585) among men and 1.346 (1.105-1.639) among women. Thus, individuals who concealed their emotions at work were significantly more likely to have a diagnosis of AR in comparison to those who did not. Because concealing emotions at work has adverse health effects, labor policies that aim to reduce this practice are needed.

Aeroallergen sensitization is related to the coexistence of allergic diseases, but the nature of this relationship is poorly understood. The aim of this study was to clarify the relationship of polysensitization with allergic multimorbidities and the severity of allergic diseases. This study is a cross-sectional analysis of 3,368 Korean children aged 6-7 years-old. We defined IgE-mediated allergic diseases based on structured questionnaires, and classified the sensitivity to 18 aeroallergens by logistic regression and the Ward hierarchical clustering method. The relationship of polysensitization (positive IgE responses against 2 or more aeroallergens classes) with allergic multimorbidities (coexistence of 2 or more of the following allergic diseases: asthma, rhinitis, eczema, and conjunctivitis) and severity of allergic diseases was determined by ordinal logistic regression analysis. The rate of polysensitization was 13.6% (n = 458, 95% CI 12.4-14.8) and that of allergic multimorbidity was 23.5% (n = 790, 95% CI 22.0-24.9). Children sensitized to more aeroallergens tended to have more allergic diseases (rho = 0.248, p < 0.001), although the agreement between polysensitization and multimorbidity was poor (kappa = 0.11, p < 0.001). The number allergen classes to which a child was sensitized increased the risk of wheezing attacks (1 allergen: adjusted odds ratio [aOR] 2.22, 4 or more allergens: aOR 9.39), absence from school (1 allergen: aOR 1.96, 3 allergens: aOR 2.08), and severity of nasal symptoms (1 allergen: aOR 1.61, 4 or more allergens: aOR 4.38). Polysensitization was weakly related to multimorbidity. However, the number of allergens to which a child is sensitized is related to the severity of IgE-mediated symptoms. © 2017 S.

Certain practical issues such as lack of clinical immunologists and specialized laboratory diagnostic facilities remain to be addressed. However, great efforts taken by passionate clinicians and scientists in the immunology networking have ascertained some prevalence. Despite the limitation, all suspected cases of PID are being properly investigated and competently managed. In this case report we highlighted the obstacles we faced in managing PID patients, particularly preparing for bone marrow transplant. This is the first transplanted case of chronic granulomatous disease in Malaysia, which emphasizes the importance of collaborative work to ensure further morbidities or mortalities are prevented.

Cat scratch disease is a common infectious disorder caused by Bartonella henselae that is transmitted primarily by kittens. It typically exhibits a benign and self-limiting course of subacute regional lymphadenopathy and fever lasting two to eight weeks. The most severe complication of cat scratch disease is involvement of the nervous system, such as encephalitis, meningitis, and polyneuritis. Peripheral facial nerve palsy associated with Bartonella infection is rare; few reported pediatric and adult cases exist and the precise pathogenesis is unknown. A previously healthy 7-year-old boy presented with fever, cervical lymphadenopathy, and peripheral facial nerve palsy associated with serologically confirmed cat scratch disease. The stapedius muscle reflex was absent on the left side and brain magnetic resonance imaging revealed a mass lesion at the left internal auditory meatus. The patient's symptoms and imaging findings were gradually resolved after the antibiotics and corticosteroids treatment. The suspected granulomatous lesion was considered to have resulted from the host's immune reaction to Bartonella infection and impaired the facial nerve. This is the first case report providing direct evidence of peripheral facial nerve palsy caused by a suspected granulomatous lesion associated with cat scratch disease and its treatment course.

The prevalence of childhood food allergy and the duration of these allergies, particularly those considered to be transient, like egg and milk allergy, are increasing. The identification of allergic individuals using minimally invasive, non-anaphylaxis-threatening methods is therefore of increasing importance. In this experiment, correlates were sought of an allergic immune response (IR) phenotype in pigs. Using pigs pre-treated with heat-killed bacteria or bacterial components before allergic sensitization with the egg white protein ovomucoid (Ovm), differences were determined in IR phenotype of pigs in the categories treated-allergic, treated-tolerant, control-allergic (CA) and control-tolerant. Phenotype was established by measuring immunoglobulin (Ig)-associated antibody activity (AbA), cytokine profiles and the proportion of blood T-regulatory cells (T-regs) and observing late-phase allergen-specific skin tests (ST). Although 100% of pigs became sensitized to Ovm, only 33% of pigs had clinical signs of allergy after oral challenge with egg white. Pigs without clinical signs were classified as clinically tolerant. Sixty-seven percent of allergic pigs had a positive, late-phase ST classified as very strong or strong, while 84% of clinically tolerant pigs did not have late-phase ST. Treated-allergic pigs and CA pigs had greater total antibody IgG (H+L), IgE and IgG1 AbA than clinically tolerant pigs. Cytokine profiles of allergic pigs and the proportion of circulating T-regs, did not differ significantly between allergic and clinically tolerant pigs. Therefore, measurement of allergen-specific IgG, IgG1 and/or IgE activity and evaluation of late-phase ID ST may be useful in identifying allergic IR phenotypes in swine models of food allergy, which may be extended toward human use.

Rainsford, K D

The severe granulomatous reactions in the liver which occur following infestation by adult Schistosoma mansonii are largely initiated by invading eosinophils and monocytes. The present studies were designed to investigate the possibility that (a) anti-inflammatory drugs could be employed beneficially to attenuate the liver granulomatous reactions in schistosomiasis, and (b) that part of the therapeutic effects of anti-schistosomal (AS) drugs might be due to possible influences on arachidonate metabolism. Therefore the effects were determined of (a) AS as compared with NSAI drugs on eicosanoid metabolism in isolated human peripheral leucocyte populations, and (b) electron-microscopic changes in the livers of mice infected with Schistosoma mansoni in response to AS and/or NSAI drugs. Of the AS drugs only praziquantel (10-100 microM) inhibited 5-HETE production by the 5-lipoxygenase pathway. No effects were observed of this or the other AS drugs on prostaglandin production. In S. mansoni infected mice, praziquantel (250 mg/kg/d), given orally with indomethacin (5 mg/kg/d) for 5 days did not improve the inflammatory reactions around worms or eggs of schistosomes. Furthermore, both indomethacin (5 mg/kg/d) alone and benoxaprofen (20 mg/kg/d for 5 days) elicited liver changes suggestive of specific liver damage by these drugs. These results suggest that liver pathology may be enhanced by NSAI drugs perhaps as a consequence of the liver metabolism of these drugs being compromised. Their use to modify inflammatory reactions at the peak of liver schistosome infections may thus be contraindicated.

The phenomenon of allergy transfer from an allergic donor to a non-allergic recipient via hematopoietic cell transplantation has been described by several reports. However, it could not yet been conclusively shown that allergic reaction of the recipient is elicited by the donor's cells. In the case of a 46-year-old male patient who - for the first time in his life - had two episodes of oral allergic syndrome upon kiwi consumption after having received myeloablative hematopoietic stem cell transplantation (HCT) from his kiwi-allergic sister, we aimed to clarify the origin of allergen reactive cells in the donor. We not only intended to demonstrate if allergy was transferred by HCT but also to present an experimental workup for the analysis of allergy transfer by HCT. Allergic sensitization to kiwi in recipient and donor was proven by ImmunoCAP. Furthermore, origin of peripheral blood mononuclear cells (PBMCs) was analyzed by chromosomal fluorescence in situ hybridization (FISH). To confirm allergic reaction and activation of hematopoietic cells by customized kiwi extract, we performed basophil activation test from whole blood as well as T cell proliferation assays from purified PBMCs of both recipient and donor. Basophil activation upon kiwi extract was demonstrated in both recipient and donor. Besides, we showed proliferation of CD4(+) T cells after incubation with kiwi extract. FISH analysis proved that hematopoietic cells of the male recipient completely originated from the female donor. Exemplified in this patient, we show for the first time that allergy transfer is mediated by the donor's cells. Moreover, our experimental approach using customized kiwi extract to prove contribution of kiwi-specific T and B cells in both kiwi-allergic recipient and donor could serve as a model approach for future studies. © 2016 European Academy of Dermatology and Venereology.

Despite its high prevalence, early onset and chronic nature, the causes of asthma are not clearly established. The present study examined a plausible but untested relationship in the development of non-allergic asthma; an asthma phenotype closely linked to deprivation and other preventable risk factors. Our aim was to determine the mediating role of adiposity in the relationship between socioeconomic position in infancy and non-allergic asthma emergence in mid-childhood. To estimate the causal indirect effect of adiposity we applied the parametric g-computational procedure to 6203 singleton children from the UK Millennium Cohort Study. Adiposity was measured at age 7 by body mass index, waist circumference and waist circumference-to-height ratio. Children who developed non-allergic asthma between the age of 7 and 14 were compared with children without allergies or allergic asthma at these ages. We found no evidence to suggest that adiposity is a mediator in the relationship between socioeconomic position and the development of non-allergic asthma in mid-childhood. After adjustment for risk factors, the direct effect of socioeconomic position remained; children in the lowest tertile of socioeconomic position had a 43% (OR 1.43, 95% CI 1.38 to 1.49) greater odds of developing non-allergic asthma compared with the highest tertile. Adiposity at age 7 does not mediate the relationship between socioeconomic position and non-allergic asthma. The results suggest that improving socioeconomic conditions and promoting healthy weight are both important in reducing the development of non-allergic asthma in early to mid-childhood. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Up to 35% of the population modify their diet for adverse reactions to food. This study described the food choice behaviour of diagnosed food-allergic (DFA), self-reported food-allergic or intolerant (SFA) and nonfood-allergic (NFA) consumers, and explored differences between them. Six focus groups with adults (n = 44) were conducted. Data analysis was performed using thematic content analysis. Compared to NFA participants, DFA consumers were deprived of satisfaction and pleasure from foods, experienced difficulties finding safe foods and had to be organized with eating. SFA participants faced similar problems, but to a lesser degree; their food choices were strongly influenced by emotional factors or health awareness. Food-allergic consumers' food choices are influenced by a number of factors that differ to those of NFA consumers. It is therefore important to offer people with food allergies or intolerances advice that goes beyond how to avoid allergens. © 2012 John Wiley & Sons A/S.

Do air cleaners make a difference in treating allergic disease in homes?

PubMed

Reisman, R E

2001-12-01

The purpose of this review is to objectively critique available data regarding the clinical benefits of room air cleaners and to provide physicians and patients with a reasonable recommendation of their utility in treatment of inhalant allergic disease. Data were obtained from published studies and reviews. The specific reviewed studies met the following criteria: 1) selection of patients with clinical allergic disease confirmed by detection of allergen-specific immunoglobulin E; 2) use of an effective air filter; 3) clinical and laboratory evaluation of results; and 4) measurement of the results of air filtration on environmental allergen or airborne particulate levels. The studies were conducted in a double-blind manner. Conclusions of two previous reviews are also incorporated in this paper. The results of the published studies and summary reviews show minimal, if any, effectiveness of room air cleaners in treatment of allergic respiratory disease. Room air cleaners should not be recommended for people with inhalant allergic disease.

Cocamide DEA (CAS no. 68603-42-9) is a non-ionic surfactant frequently used in industrial, household and cosmetic products for its foam-producing and stabilizing properties. Contact allergy has been reported quite rarely in the past, but recently several cases were published, raising the question of an increase in the frequency of allergic dermatitis caused by this substance. To describe cocamide DEA-allergic patients and their characteristics observed in our department. Medical charts of patients, investigated between 1990 and December 2015, were retrospectively reviewed for cocamide DEA-allergy. Demographic characteristics and patch test results were analyzed. Out of 1767 patients tested, 18 (1%) presented with an allergic reaction to cocamide DEA, all of them at least with hand dermatitis. Twelve patients had (past) occupational exposure to cocamide DEA. Out of the 18 patients, 15 showed (most often) multiple positive reactions and 7 also suffered from atopic dermatitis. Cocamide DEA allergy is relatively rare, despite frequent use, and an increasing trend was not observed. Reactions to cocamidopropyl betaine and cocamide MEA only occurred in some of the subjects tested. Shampoos and liquid hand soaps/cleansers dominated as sources of exposure. All patients presented with an impaired skin barrier due to atopic and/or previous contact dermatitis. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

PULMONARY MYCOTIC INFECTIONS—Allergic and Immunologic Factors

PubMed Central

Keeney, Edmund L.

1954-01-01

The mechanisms of immunity and allergy, at play in every infectious disease, must be comprehended before the pathogenesis of an infection can be appreciated. Immunity, allergy and serology are concerned with specific antigen-antibody reactions. In immunity the principal concern is with the final disposition of antigen (agglutination, lysis, and phagocytosis). In allergy attention is focused upon tissue damage resulting from antigen-antibody union. In serology interest is devoted to the presence of antibody as evaluated by certain visible in vitro reactions—precipitin, agglutination, opsonization and complement fixation tests. There are two types of allergic reaction—the immediate or anaphylactic type and the delayed type or the allergic disease of infection. Neither kind takes part in the mechanism of immunity. At this time the allergic antibody and the immune antibody must be considered as two different and distinct antibodies. Skin and serologic tests are important diagnostic aids in certain pulmonary mycotic infections—for example, coccidioidomycosis, blastomycosis, histoplasmosis and moniliasis. Clinical expressions of allergy may appear in coccidioidomycosis, histoplasmosis and moniliasis. Pulmonary mycoses are divided into three groups, that is, the endogenous mycoses (actinomycosis, moniliasis, geotrichosis), the endogenous-exogenous mycoses (cryptococcosis, aspergillosis, mucormycosis) and the exogenous mycoses (nocardiosis, coccidioidomycosis, histoplasmosis, North American blastomycosis). The diagnosis and treatment of the important mycotic infections that invade lung tissue are discussed. PMID:13209369

The characteristics of mesenchymal stem cells (MSCs) derived from human turbinates (hTMSCs) have not been investigated in allergic rhinitis. We evaluated the influence of allergic state of the donor on the characteristics, proliferation, and differentiation potential of hTMSCs, compared with hTMSCs derived from non-allergic patients. hTMSCs were isolated from five non-allergic and five allergic patients. The expression of toll-like receptors (TLRs) in hTMSCs was measured by FACS, and cell proliferation was measured using a cell counting kit. Cytokine secretion was analyzed using multiplex immunoassays. The osteogenic, chondrogenic, and adipogenic differentiation potentials of hTMSCs were evaluated by histology and gene expression analysis. In allergic patients, FACS analysis showed that TLR3 and TLR4 were more highly expressed on the surface of hTMSCs than TLR2 and TLR5. The proliferation of hTMSCs was not influenced by the presence of TLR priming. The expression of IL-6, IL-8, IL-12, IP-10, and RANTES was upregulated after the TLR4 priming. The differentiation potential of hTMSCs was not influenced by TLR priming. These characteristics of hTMSCs were similar to those of hTMSCs from non-allergic patients. We conclude that the allergic condition of the donor does not influence TLR expression, proliferation, or immunomodulatory potential of hTMSCs. PMID:26376485

The allergen challenge test has been the mainstay of diagnosis of allergic diseases for a long time since it offers a direct proof of the clinical relevance of a particular allergen for the allergic disease symptoms and severity. Standardisation and availability for daily practice (including safety issues) are still to be refined but most of the challenge tests have safely crossed the border from research tools to diagnostic tests available for daily practice for a well trained clinical staff. © 2015 John Wiley & Sons A/S.

Allergic colitis shows overlap with classic inflammatory bowel disease (IBD). Clinically, allergic colitis is associated with dysmotility and abdominal pain, and mucosal eosinophilia is characteristic. We thus aimed to characterise mucosal changes in children with allergic colitis compared with normal tissue and classic IBD, focusing on potential interaction between eosinophils and mast cells with enteric neurones. A total of 15 children with allergic colitis, 10 with Crohn disease (CD), 10 with ulcerative colitis (UC), and 10 histologically normal controls were studied. Mucosal biopsies were stained for CD3 T cells, Ki-67, eotaxin-1, and eotaxin-2. Eotaxin-2, IgE, and tryptase were localised compared with mucosal nerves, using neuronal markers neurofilament protein, neuron-specific enolase, and nerve growth factor receptor. Overall inflammation was greater in patients with CD and UC than in patients with allergic colitis. CD3 T-cell density was increased in patients with allergic colitis, similar to that in patients with CD but lower than in patients with UC, whereas eosinophil density was higher than in all other groups. Eotaxin-1 and -2 were localised to basolateral crypt epithelium in all specimens, with eotaxin-1+ lamina propria cells found in all of the colitis groups. Eotaxin-2+ intraepithelial lymphocyte (IEL) density was significantly higher in allergic colitis specimens than in all other groups. Mast cell degranulation was strikingly increased in patients with allergic colitis (12/15) compared with that in patients with UC (1/10) and CD (0/1). Tryptase and IgE colocalised on enteric neurons in patients with allergic colitis but rarely in patients with IBD. Eotaxin-2+ IELs may contribute to the periepithelial eosinophil accumulation characteristic of allergic colitis. The colocalisation of IgE and tryptase with mucosal enteric nerves is likely to promote the dysmotility and visceral hyperalgesia classically seen in allergic gastrointestinal inflammation.

2018-01-01

Allergic diseases are chronic inflammatory disorders in which there is failure to mount effective tolerogenic immune responses to inciting allergens. The alarming rise in the prevalence of allergic diseases in recent decades has spurred investigations to elucidate the mechanisms of breakdown in tolerance in these disorders and means of restoring it. Tolerance to allergens is critically dependent on the generation of allergen-specific regulatory T (Treg) cells, which mediate a state of sustained non-responsiveness to the offending allergen. In this review, we summarize recent advances in our understanding of mechanisms governing the generation and function of allergen-specific Treg cells and their subversion in allergic diseases. We will also outline approaches to harness allergen-specific Treg cell responses to restore tolerance in these disorders. PMID:29375821

Nondietary exposure to milk proteins may be a risk for children who do not outgrow milk allergy by school age. To study the allergenicity of casein containing chalk. A 6-year-old, milk allergic child developed asthma and rhinoconjunctivitis while in school. The suspected cause was dust-free chalk containing casein. To study the relationship of dust-free chalk containing casein with asthma and rhinoconjunctivitis, 13 additional milk allergic patients were studied: 3 school-aged children, 8 preschool-aged infants, and 2 children with outgrown milk allergy. Skin tests and/or specific IgE with chalk and casein were performed. A chalk use test was performed in older children. Milk allergens contained in chalk were characterized by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, immunoblot, and IgE inhibition experiments. All school-aged, milk allergic children were exposed to chalk and reported symptoms attributed to chalk exposure. The skin test result to chalk was positive in 5 of 12 cases, and the specific IgE test result was positive in all 12 study participants in which it was performed. Casein strongly inhibited the binding of IgE to chalk. Chalk sodium dodecyl sulfate-polyacrylamide gel electrophoresis showed proteins with molecular weight similar to caseins. Immunoblot demonstrated strong binding of IgE to chalk in a blurred pattern and a band at 30 kDa, inhibited by casein. The chalk challenge test result was positive in 2 school-age children who had a positive skin test result to chalk. Their symptoms improved after avoidance of chalk in the school. In 2 other cases in which the challenge test result was negative, chalk was reintroduced without problems. Inhalation of chalk dust containing casein can induce asthma symptoms in milk allergic patients. Hidden and nondietary sources of exposure should always be considered in food allergic patients.

It has been hypothesized that n-3 PUFA in breast milk may assist immune and lung development. There are very limited data on possible long-term effects on allergic disease and lung function. The aim was to investigate associations of n-3 and n-6 PUFA levels in colostrum and breast milk with allergic disease and lung function at ages 12 and 18 years. Polyunsaturated fatty acids were measured in 194 colostrum samples and in 118 three-month expressed breast milk samples from mothers of children enrolled in the Melbourne Atopy Cohort (MACS) Study, a high-risk birth cohort study. Associations with allergic diseases, skin prick tests and lung function assessed at 12 and 18 years were estimated using multivariable regression. Higher levels of n-3 but not n-6 PUFAs in colostrum were associated with a trend towards increased odds of allergic diseases, with strong associations observed for allergic rhinitis at 12 (OR = 5.69[95% CI: 1.83,17.60] per weight%) and 18 years (4.43[1.46,13.39]) and eczema at 18 years (9.89[1.44, 68.49]). Higher levels of colostrum n-3 PUFAs were associated with reduced sensitization (3.37[1.18, 9.6]), mean FEV 1 (-166 ml [-332, -1]) and FEV 1 /FVC ratio (-4.6%, [-8.1, -1.1]) at 12 years. Higher levels of colostrum n-3 PUFAs were associated with increased risks of allergic rhinitis and eczema up to 18 years, and sensitization and reduced lung function at 12 years. As residual confounding may have caused these associations, they should be replicated, but these results could indicate that strategies that increase maternal n-3 PUFA intake may not aid in allergic disease prevention. © 2016 John Wiley & Sons A/S.

Pinocembrin (5, 7- dihydroxy flavanone) is the most abundant chiral flavonoid found in propolis, exhibiting antioxidant, antimicrobial and anti-inflammatory properties. However, the effect of Pinocembrin on allergic response is unexplored. Thus, current study aimed at investigating the effects of Pinocembrin on IgE-mediated allergic response in vitro. A special emphasis was directed toward histidine decarboxylase (HDC) and other pro-allergic and pro-inflammatory mediators. Preliminary studies, using a microbiological model of Klebsiella pneumoniae, provided first evidences that suggest Pinocembrin as a potential thermal stable inhibitor for HDC. Applying docking analysis revealed possible interaction between Pinocembrin and mammalian HDC. In vitro studies validated the predicted interaction and showed that Pinocembrin inhibits HDC activity and histamine in IgE-sensitized RBL-2H3 in response to dinitrophenol (DNP)-bovine serum albumin (BSA) stimulation. In addition, Pinocembrin mitigated the damage in the mitochondrial membrane, formation of cytoplasmic granules and degranulation as indicated by lower β-hexoseaminidase level. Interestingly, it reduced range of pro-inflammatory mediators in the IgE-mediated allergic response including tumor necrosis factor (TNF)-α, interleukin (IL)-6, nitric oxide (NO), inducible NO synthase (iNOS), phosphorylation of inhibitory kappa B (IкB)-α, prostaglandin (PGE)-2 and cyclooxygenase (COX)-2. In conclusion, current study suggests Pinocembrin as a potential HDC inhibitor, and provides the first evidences it is in vitro anti-allergic properties, suggesting Pinocembrin as a new candidate for natural anti-allergic drugs.

Endoplasmic reticulum (ER) stress-induced unfolded protein response plays a critical role in inflammatory diseases, including allergic airway disease. However, the benefits of inhibiting ER stress in the treatment of allergic airway disease are not well known. Herein, we tested the therapeutic potential of a chemical chaperone, tauroursodeoxycholic acid (TUDCA), in combating allergic asthma, using a mouse model of house dust mite (HDM)-induced allergic airway disease. TUDCA was administered during the HDM-challenge phase (preventive regimen), after the HDM-challenge phase (therapeutic regimen), or therapeutically during a subsequent HDM rechallenge (rechallenge regimen). In the preventive regimen, TUDCA significantly decreased HDM-induced inflammation, markers of ER stress, airway hyperresponsiveness (AHR), and fibrosis. Similarly, in the therapeutic regimen, TUDCA administration efficiently decreased HDM-induced airway inflammation, mucus metaplasia, ER stress markers, and AHR, but not airway remodeling. Interestingly, TUDCA administered therapeutically in the HDM rechallenge regimen markedly attenuated HDM-induced airway inflammation, mucus metaplasia, ER stress markers, methacholine-induced AHR, and airway fibrotic remodeling. These results indicate that the inhibition of ER stress in the lungs through the administration of chemical chaperones could be a valuable strategy in the treatment of allergic airway diseases.

Severe allergic reactions of unknown etiology,necessitating a hospital visit, have an important impact in the life of affected individuals and impose a major economic burden to societies. The prediction of clinically severe allergic reactions would be of great importance, but current attempts have been limited by the lack of a well-founded applicable methodology and the wide spatiotemporal distribution of allergic reactions. The valid prediction of severe allergies (and especially those needing hospital treatment) in a region, could alert health authorities and implicated individuals to take appropriate preemptive measures. In the present report we have collecterd visits for serious allergic reactions of unknown etiology from two major hospitals in the island of Crete, for two distinct time periods (validation and test sets). We have used the Normalized Difference Vegetation Index (NDVI), a satellite-based, freely available measurement, which is an indicator of live green vegetation at a given geographic area, and a set of meteorological data to develop a model capable of describing and predicting severe allergic reaction frequency. Our analysis has retained NDVI and temperature as accurate identifiers and predictors of increased hospital severe allergic reactions visits. Our approach may contribute towards the development of satellite-based modules, for the prediction of severe allergic reactions in specific, well-defined geographical areas. It could also probably be used for the prediction of other environment related diseases and conditions.

It could also probably be used for the prediction of other environment related diseases and conditions. PMID:25794106

Environmental factors have been found to be associated with allergic diseases, but it is unclear which environmental factor during which exposure window causes what kind of allergic diseases. We investigated association between exposure to some predominant outdoor and indoor environmental factors during preconceptional, prenatal, and postnatal periods and allergic diseases/symptoms in 2598 children in China. Children's lifetime incidence of allergic diseases and current prevalence of allergic symptoms and exposure to indoor new furniture/redecoration and mold/dampness was surveyed by a questionnaire. Exposure to outdoor air pollutants was estimated by the concentrations measured at air quality monitoring stations. Multiple logistic regression model was used to evaluate the associations between outdoor air pollutants and indoor environmental factors and allergic diseases (asthma, allergic rhinitis, and eczema) and symptoms (wheezing, night cough, and rhinitis-like). We found that preconceptional, prenatal, and postnatal exposure to outdoor industrial and traffic air pollutants were significantly associated with increase in the risk of childhood asthma, and also positively associated with allergic rhinitis and eczema. However, we cannot distinguish the effect of outdoor air pollutants and exposure windows because of their high correlations. New furniture was associated with eczema and allergic rhinitis during postnatal exposure, but redecoration associated with asthma and eczema during prenatal exposure. Indoor visible mold/damp stains was significant for eczema during prenatal exposure and asthma during postnatal exposure respectively, but window condensation was significant for all childhood allergic diseases during both prenatal and postnatal exposures. Allergic symptoms in children were found to be associated with exposure to indoor factors only.

Allergen immunotherapy for allergic respiratory diseases

PubMed Central

Cappella, Antonio; Durham, Stephen R.

2012-01-01

Allergen specific immunotherapy involves the repeated administration of allergen products in order to induce clinical and immunologic tolerance to the offending allergen. Immunotherapy is the only etiology-based treatment that has the potential for disease modification, as reflected by longterm remission following its discontinuation and possibly prevention of disease progression and onset of new allergic sensitizations. Whereas subcutaneous immunotherapy is of proven value in allergic rhinitis and asthma there is a risk of untoward side effects including rarely anaphylaxis. Recently the sublingual route has emerged as an effective and safer alternative. Whereas the efficacy of SLIT in seasonal allergy is now well-documented in adults and children, the available data for perennial allergies and asthma is less reliable and particularly lacking in children. This review evaluates the efficacy, safety and longterm benefits of SCIT and SLIT and highlights new findings regarding mechanisms, potential biomarkers and recent novel approaches for allergen immunotherapy.

Chapman, Martin D.; Wünschmann, Sabina

2016-01-01

Purpose of review The purpose of this review is to evaluate the most recent findings on indoor allergens and their impact on allergic diseases. Recent findings Indoor allergens are present inside buildings (home, work environment, school), and given the chronic nature of the exposures, indoor allergies tend to be associated with the development of asthma. The most common indoor allergens are derived from dust mites, cockroaches, mammals (including wild rodents and pets), and fungi. The advent of molecular biology and proteomics has led to the identification, cloning, and expression of new indoor allergens, which have facilitated research to elucidate their role in allergic diseases. This review is an update on new allergens and their molecular features, together with the most recent reports on their avoidance for allergy prevention and their use for diagnosis and treatment. Summary Research progress on indoor allergens will result in the development of new diagnostic tools and design of coherent strategies for immunotherapy. PMID:27184001

Occupational contact allergic dermatitis in dentistry.

Dental professionals may be at increased risk of developing occupational allergic diseases specially to methacrylates that can permeate protective disposable gloves. We presented a case of occupational allergic contact dermatitis in a 28-year-old dental technician. The patient had complained of itching and cracking of fingers for 6 months. The dermatitis improved over weekends. Skin erythema and scaling were present with primarily involvement of the fingertips. Patch testing with dental series gave positive vesicular reaction to methyl methacrylate. Follow-up after 6 months of allergen avoidance showed a complete regression of dermatitis. Methacrylates serve as bases for acrylic resins which are used in prosthetics. Methyl methacrylate as a small molecular acrylate can permeate thin protective disposable gloves. Using adequate personal protective equipment, like nitrile rubber gloves, is the most important preventive measure in this occupation. Health practitioners should recognize possible occupational hazards in dentistry and implement appropriate preventive measures to protect health of workers.

Introduction The III Brazilian Consensus on Rhinitis (2012) defines allergic rhinitis as a nasal mucosa inflammation, mediated by immunoglobulin E, after exposure to allergens. The classic signs and symptoms of allergic rhinitis are nasal obstruction, watery rhinorrhea, sneezing, and nasal itching, often reversible either spontaneously or with treatment, and mouth breathing (breathing predominantly through the mouth, regardless of the cause, due to a nasal breathing impairment) in some cases. Objective To evaluate the literature on masticatory changes in children with mouth breathing due to allergic rhinitis. Methods We conducted a search of the past 10 years, at Bireme and MEDLINE databases, for articles that covered masticatory changes in children with mouth breathing secondary to allergic rhinitis. Results We found 1,986 articles, including 15 repeated in databases, but only two articles met the inclusion criteria fully. Discussion We found few studies to answer the question raised in this review, and those studies have some methodological limitations. Most articles claimed no have statistically significant differences in masticatory changes in this population. Conclusion A better controlled study (isolating diseases, exposure time), with a larger sample (sample calculation appropriate), would be necessary to examine such changes.

Herbert, Linda J; Dahlquist, Lynnda M

2008-12-01

This study examined autonomy, anxiety, depression, and perceptions of parental behavior in 86 food allergic young adults and 344 healthy young adults between the ages of 18 and 22. Participants completed an online survey measuring self-reported autonomy, anxiety, depression, and perceptions of parental behavior. Results indicated that, as a group, food allergic young adults did not differ from healthy peers. However, food allergic young adults who reported having experienced an anaphylactic reaction described their disease as more severe, reported more worry about their disease, and rated their parents as more overprotective than food allergic young adults who reported never having experienced anaphylaxis. The experience of anaphylaxis may be a reliable indicator of food allergic individuals who are at risk for psychological distress.

Fetal growth and risk of childhood asthma and allergic disease

2012-01-01

Introduction Early genetic and environmental factors have been discussed as potential causes for the high prevalence of asthma and allergic disease in the western world, and knowledge on fetal growth and its consequence on future health and disease development is emerging. Objective This review article is an attempt to summarize research on fetal growth and risk of asthma and allergic disease. Current knowledge and novel findings will be reviewed and open research questions identified, to give basic scientists, immunologists and clinicians an overview of an emerging research field. Methods PubMed-search on pre-defined terms and cross-references. Results Several studies have shown a correlation between low birth weight and/or gestational age and asthma and high birth weight and/or gestational age and atopy. The exact mechanism is not yet clear but both environmental and genetic factors seem to contribute to fetal growth. Some of these factors are confounders that can be adjusted for, and twin studies have been very helpful in this context. Suggested mechanisms behind fetal growth are often linked to the feto-maternal circulation, including the development of placenta and umbilical cord. However, the causal link between fetal growth restriction and subsequent asthma and allergic disease remains unexplained. New research regarding the catch-up growth following growth restriction has posited an alternative theory that diseases later on in life result from rapid catch-up growth rather than intrauterine growth restriction per se. Several studies have found a correlation between a rapid weight gain after birth and development of asthma or wheezing in childhood. Conclusion and clinical relevance Asthma and allergic disease are multifactorial. Several mechanisms seem to influence their development. Additional studies are needed before we fully understand the causal links between fetal growth and development of asthma and allergic diseases. PMID:22994341

Orthodontists frequently treat children with mouth breathing. The purpose of the present study was to examine dental positions, skeletal effects and the pharyngeal airway space of children with chronic allergic rhinitis, when compared with a control group exhibiting a normal breathing pattern. Seventy Caucasian children from Santa Maria University Hospital - North Lisbon Hospital Center were evaluated, between September 2009 and February 2013. The study group comprised of 35 children with chronic allergic rhinitis, both genders, aged 5 - 14, with positive reaction to allergens, mouth breathing and malocclusion. The control group was composed of 35 children, both genders, displaying normal nasal breathing and malocclusion, who resorted to the orthodontic department. Measures of Ricketts, Steiner and McNamara's analysis were used and the t- Student test was applied to the data obtained. Statistically significant differences were observed between the oral and nasal breathers, respectively: lower facial height (49.1/45.9 mm), Frankfurt â mandibular plane angle (30.1/26.9º) and Sela-Nasion - oclusal plane angle (17.3/15º), maxillary length (78.4/82.4 mm), mandibular length (102.4/107 mm), overbite (0.8/3.1mm) and overjet (4/4.7 mm). Comparison between the allergic rhinitis and control group showed that there is an increased lower facial height, larger Frankfurt â mandibular plane angle and Sela-Nasion oclusal plane angle in children with chronic allergic rhinitis. This group also had a shorter maxillary and mandibular length, less overbite and decreased upper airway space. Children with allergic rhinitis and mouth breathing have longer faces, shorter maxillas and mandibles and a narrowed pharyngeal airway space. No statistical differences between the groups in sagital relationships or in dental inclinations were found.

Allergic Reaction to Ketamine as Monotherapy for Procedural Sedation.

PubMed

Nguyen, Tammy T; Baker, Bethany; Ferguson, Jeffrey D

2017-04-01

Ketamine is a cyclohexamine derivative that acts as a noncompetitive N-methyl D-aspartate receptor antagonist. Its use for procedural sedation is recommended by national clinical policy. However, its immunogenic potential is not well documented. We report a case of allergic reaction associated with the administration of intravenous ketamine for procedural sedation in a 16-year-old male. Minutes after administration, the patient developed a morbilliform, erythematous rash that extended to the upper and lower torso and resolved with intravenous diphenhydramine. It is most likely that this allergic reaction was caused by a ketamine-induced histamine release that has been described in vitro. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This is the first case report in which ketamine was used as monotherapy in the emergency department for the facilitation of procedural sedation that resulted in an allergic reaction. Supportive measures, including advanced airway procedures and hemodynamic support, may be necessary in more severe anaphylactic cases. Providers should be aware of this potential adverse effect when using ketamine for procedural sedation. Copyright © 2016 Elsevier Inc. All rights reserved.

2007-01-01

The purpose of this study was to analyze the relation between clinical picture of allergic disease and the level of pollen count the patients are exposed to. We analyzed the severity of allergic rhinitis, conjunctivitis and bronchial asthma in a group of 640 subjects from Warsaw area with hypersensitivity to hazel, alder, grass, mugwort, plantain, nettle, Alternaria and Cladosporium allergens. Aerobiological measurements, patients' symptoms score cards and the results of physical examination were analyzed. First symptoms in patients allergic to grass were visible during exposure to the concentration of 20 pollen grains in 1 m3 of air (25% subjects sensitised to grass pollen). Symptoms were noted in all the subjects sensitized to grass pollen at a concentration of approximately 50 grains/m3 of air. During exposure to the concentration of 65 pollen grains per m3 the symptoms were strengthened. Several hours' exposure to grass pollen concentration exceeding 120 grains/m3 cause dyspnoea in some patients. Similar intensive symptoms occurred after exposure to alder, birch and mugwort pollen. Patients with positive skin prick tests to plantain and nettle pollen allergens experienced symptoms of low intensity or even none symptoms during pollination period. Subjects with hypersensitivity to Alternaria allergens experienced symptoms during exposure to the concentration of approximately 80 spores in 1 m3 of air, while patients sensitised to Cladosporium allergens, during exposure to the concentration of over 2800 spores in 1 m3 of air. The dominant symptom occurring in patients sensitized to fungal allergens was loss of nasal patency, and dyspnoea as well as recurring cough at higher concentrations. Clinical symptoms of allergic disease were connected to the concentration and the kind of aeroallergen the subjects were exposed to.

The active contribution of Toll-like receptors to allergic airway inflammation.

Epithelia lining the respiratory tract represent a major portal of entry for microorganisms and allergens and are equipped with innate and adaptive immune signaling receptors for host protection. These include Toll-like receptors (TLRs) that recognize microbial components and evoke diverse responses in cells of the respiratory system. TLR stimulation by microorganism-derived molecules activates antigen presenting cells, control T helper (Th) 1, Th2, and Th17 immune cell differentiation, cytokine production by mast cells, and activation of eosinophils. It is clear that TLR are involved in the pathophysiology of allergic airway diseases such as asthma. Dendritic cells (DCs), a kind of antigen presenting cells, which play a key role in the induction of allergic airway inflammation, are privileged targets for pathogen associated molecular patterns (PAMPs). During the allergic responses, engagement of TLRs on DCs determines the Th2 polarization of the T cells. TLR signaling in mast cells increases the release of IL-5, and TLR activation of airway epithelial cells forces the generation of proallergic Th2 type of cytokines. Although these responses aim to protect the host, they may also result in inflammatory tissue damage in the airway. Under certain conditions, stimulation of TLRs, in particular, TLR9, may reduce Th2-dependent allergic inflammation by induction of Th1 responses. Therefore, understanding the complex regulatory roles of TLRs in the pathogenesis of allergic airway inflammation should facilitate the development of preventive and therapeutic measures for asthmatic patients.

[Allergic Rhinitis and its Impact on Asthma (ARIA) in Latin America].

PubMed

Baena-Cagnani, Carlos E

2002-01-01

Allergic rhinitis is the commonest chronic respiratory disorder in children and young adults having an important impact for those suffering this condition, as well as for the public health. Allergic rhinitis is frequently associated to other co-morbidities, particularly asthma and conjunctivitis but, also, sinusitis and otitis media. Most of patients suffering rhinitis are cared by GPs and pediatricians and there are evidences that allergic rhinitis is undertreated, particularly the moderate/severe persistent forms. Clinical guidelines have become an important tool providing recommendations for diagnosis and treatment of different medical conditions. They help the process of decision making for GPs and pediatricians, and many of them, contain an update on basic science and epidemiology. In respiratory medicine, guidelines on asthma and rhinitis are available; however, they do not look at the patients globally and focus the disorder on an organ-specific basis without recommendations on co-morbidities. ARIA, Allergic rhinitis and its impact on asthma, has not been developed only to update specialists in allergy/immunology, otorhinolaryngology and neumology on rhinitis and its comorbidities but, also, to provide recommendations for non-specialists. A new classification and severity of allergic rhinitis is proposed replacing the classic perennial and seasonal forms for persistent and intermittent, mild to moderate/severe. ARIA is an initiative in collaboration with the World Health Organization and the master document has been endorsed by many national and international scientific societies and organizations. ARIA is an evidence-based document also stressing on pediatric aspects and providing recommendations for low-income countries.

Objectives Stress is considered a causal factor in many diseases, allergic disease being one of them. The prevalence of allergic disease is increasing in Korea, but the relationship between allergic symptoms and stress is not empirically well known. We aimed to evaluate the relationship between allergy-related symptoms and stress in children and adolescents. Methods We investigated 698 children and adolescents living in Gwangyang Bay, Korea, using a multi-stage cluster sampling method. Using the International Study of Asthma and Allergies in Childhood and the Psychosocial Well-being Index, these subjects were surveyed on allergy-related symptoms and psychosocial stressors in their lives, respectively. We used a multivariate logistic analysis for odds ratios for the complaint rate of allergic symptoms, after adjusting for age, gender, household income, body mass index, and residence. Results After adjustments, lifetime rhinitis (odds ratio [OR], 1.024), rhinoconjunctivitis (OR, 1.090), diagnosis of itchy eczema (OR, 1.040), treatment of itchy eczema (OR, 1.049), 12-month allergic conjunctivitis (OR, 1.026), diagnosis of allergic conjunctivitis (OR, 1.031), and treatment of allergic conjunctivitis (OR, 1.034) were found to be significantly associated with stress. Conclusions Our results support the notion that there is a relationship between stress and allergic symptoms in children and adolescents. Further research into any causal relationship between stress and allergies, as well as preventative public health plans for decreasing stress in children and adolescents are needed. PMID:23230467

To present the author's experience with various treatment methods of granulomatous lobular mastitis (GLM) and to determine effective treatment methods of GLM. Fifty patients who were diagnosed with GLM were classified into five groups based on the initial treatment methods they underwent, which included observation (n = 8), antibiotics (n = 3), steroid (n = 13), drainage (n = 14), and surgical excision (n = 12). The treatment processes in each group were examined and their clinical characteristics, treatment processes, and results were analyzed respectively. Success rates with each initial treatment were observation, 87.5%; antibiotics, 33.3%; steroids, 30.8%; drainage, 28.6%; and surgical excision, 91.7%. In most cases of observation, the lesions were small and the symptoms were mild. A total of 23 patients underwent surgical excision during treatment. Surgical excision showed particularly fast recovery, high success rate (90.3%) and low recurrence rate (8.7%). The clinical course of GLM is complex and the outcome of each treatment type are variable. Surgery may play an important role when a lesion is determined to be mass-forming or appears localized as an abscess pocket during breast examination or imaging study.

Background. Asthma and allergic rhinitis are highly prevalent conditions that cause major illness worldwide. This study aimed to assess the association between allergic rhinitis and asthma control in Peruvian school children. Methods. A cross-sectional study was conducted among 256 children with asthma recruited in 5 schools from Lima and Callao cities. The outcome was asthma control assessed by the asthma control test. A score test for trend of odds was used to evaluate the association between allergic rhinitis severity and the prevalence of inadequate asthma control. A generalized linear regression model was used to estimate the adjusted prevalence ratios of inadequate asthma control. Results. Allergic rhinitis was present in 66.4% of the population with asthma. The trend analysis showed a positive association between allergic rhinitis and the probability of inadequate asthma control (P < 0.001). It was associated with an increased prevalence of inadequate asthma control, with adjusted prevalence ratios of 1.53 (95% confidence interval: 1.19−1.98). Conclusion. This study indicates that allergic rhinitis is associated with an inadequate level of asthma control, giving support to the recommendation of evaluating rhinitis to improve asthma control in children.

Sarcoidosis (SARC) and extrinsic allergic alveolitis (EAA) share certain markers, making a differential diagnosis difficult even with histopathological investigation. In lung tissue, proteinase-activated receptor-2 (PAR-2) is primarily investigated with regard to epithelial and inflammatory perspectives. Varying levels of certain chemokines can be a useful tool for distinguishing EAA and SARC. Thus, in the present study, differences in the levels of transforming growth factor (TGF)-β1, tumor necrosis factor (TNF)-α, interleukin-4 receptor (IL-4R) and PAR-2 in bronchoalveolar lavage fluid (BALF) were compared, using an ELISA method, between 14 patients with EAA and six patients with SARC. Statistically significant higher levels of IL-4R, PAR-2 and the PAR-2/TGF-β1 and PAR-2/TNF-α ratios were observed in EAA patients as compared with SARC patients. Furthermore, the ratios of TNF-α/total protein, TGF-β1/PAR-2 and TNF-α/PAR-2 were significantly lower in EAA patients than in SARC patients. The results indicated a higher detection of PAR-2 in EAA samples in association with TNF-α and TGF-β levels. As EAA and PAR-2 in parallel belong to the Th2-mediated pathway, the results significantly indicated an association between this receptor and etiology. In addition, the results indicated that SARC is predominantly a granulomatous inflammatory disease, thus, higher levels of TNF-α are observed. Therefore, the detection of PAR-2 and investigated chemokines in BALF may serve as a useful tool in the differential diagnosis between EAA and SARC.

Intestinal epithelial stress or damage may contribute to allergic sensitization against certain food antigens. Hence, the present study investigated whether impairment of intestinal barrier integrity by the mycotoxin deoxynivalenol (DON) contributes to the development of whey-induced food allergy in a murine model. C3H/HeOuJ mice, orally exposed to DON plus whey once a week for 5 consecutive weeks, showed whey-specific IgG1 and IgE in serum and an acute allergic skin response upon intradermal whey challenge, although early initiating mechanisms of sensitization in the intestine appeared to be different compared with the widely used mucosal adjuvant cholera toxin (CT). Notably, DON exposure modulated tight-junction mRNA and protein levels, and caused an early increase in IL-33, whereas CT exposure affected intestinal γδ T cells. On the other hand, both DON- and CT-sensitized mice induced a time-dependent increase in the soluble IL-33 receptor ST2 (IL-1R1) in serum, and enhanced local innate lymphoid cells type 2 cell numbers. Together, these results demonstrate that DON facilitates allergic sensitization to food proteins and that development of sensitization can be induced by different molecular mechanisms and local immune responses. Our data illustrate the possible contribution of food contaminants in allergic sensitization in humans.

Iron Supplementation Decreases Severity of Allergic Inflammation in Murine Lung

2012-01-01

The incidence and severity of allergic asthma have increased over the last century, particularly in the United States and other developed countries. This time frame was characterized by marked environmental changes, including enhanced hygiene, decreased pathogen exposure, increased exposure to inhaled pollutants, and changes in diet. Although iron is well-known to participate in critical biologic processes such as oxygen transport, energy generation, and host defense, iron deficiency remains common in the United States and world-wide. The purpose of these studies was to determine how dietary iron supplementation affected the severity of allergic inflammation in the lungs, using a classic model of IgE-mediated allergy in mice. Results showed that mice fed an iron-supplemented diet had markedly decreased allergen-induced airway hyperreactivity, eosinophil infiltration, and production of pro-inflammatory cytokines, compared with control mice on an unsupplemented diet that generated mild iron deficiency but not anemia. In vitro, iron supplementation decreased mast cell granule content, IgE-triggered degranulation, and production of pro-inflammatory cytokines post-degranulation. Taken together, these studies show that iron supplementation can decrease the severity of allergic inflammation in the lung, potentially via multiple mechanisms that affect mast cell activity. Further studies are indicated to determine the potential of iron supplementation to modulate the clinical severity of allergic diseases in humans. PMID:23029172

Background/Aim: Acute allergic rhinoconjuctivitis is the most common form of ocular allergies. The pathogenetic mechanisms are based on an immunoglobulin E (IgE)-mediated hypersensitivity reaction. On the other hand, tear osmolarity has been suggested to be an index of ocular surface damage and inflammation. These data were the motive to investigate the levels of tear osmolarity in subjects with acute allergic rhinoconjuctivitis, before and after administration of artificial tears. Patients and Methods: Forty-five subjects with acute allergic rhinoconjuctivitis were randomly divided into three groups, based on the type of artificial tears that they received: Group A (Thera tears), Group B (Wet therapy) and Group C (Tears Naturale free). The eye drops were administered six times a day for 60 days and all subjects underwent grading of subjective symptoms and clinical examination at baseline and at the end of the treatment. Results: The diagnosis of severe eye disease, which was based on ocular surface disease index (OSDI; Allergan, Inc, Irvine, CA, USA) and tear osmolarity values, concerned all patients at baseline. Although the administration of artificial tears significantly ameliorated the symptoms and the ocular variables in all groups, the results were better in the first group. Tear osmolarity was strongly and negatively correlated with tear film breakup time (BUT) and Schirmer I test at 2 months. Contrariwise, symptoms were eliminated, when tear osmolarity was decreased. Conclusion: Acute allergic rhinoconjuctivitis is characterized by tear hyperosmolarity, which can be rehabilitated with the administration of hypotonic artificial tears. PMID:29475928
