    A 35 year female with a previous history of asthma came to our observation about 10 months ago. She was dyspneic, showed small nodules (2 to 5 mm) in arms, hands and legs and had radiological evidence of pulmonary granulomatosis and pleural effusion. Diagnosis was made by means of cutaneous biopsy showing a necrotic granulomatous vasculitic lesions with eosinophilic infiltration and giant cells, consistent with allergic granulomatosis of Churg-Strauss syndrome. Steroid therapy alone (prednisone 1 mg/kg/die) led to a rapid and complete clinical and humoral remission. The patient is still doing an alternate day prednisone therapy (15 mg) and is well after a 10 months follow-up. PMID:2572542

    Cerebral mycotic angitis takes place as a secondary disease to inflammation which is precipitated on the arterial wall to the artery, most frequently the vasa vasorum, as a result of settlement of infectious embolus into there, and it is usually seen in the patient with cardiac disease. The middle cerebral artery is a major region where the lesion takes place in multitude, and it is only rarely seen in the patient having infection in the brain or dura mater. We have recently experienced a very rare case in which false aneurysm was induced in the internal carotid artery by angitis due to Aspergillus, and this report deals with case. A 26-year-old office-man: He was attacked by loss of consciousness, aphesia, right hemiparesis during work in his office. As left CAG demonstrated evidence of arteriovenous malformation, redical operation was performed. He took a favorable course postoperatively, but developed meningitis on 10th day, when massive antibiotic therapy was started. During treatment, however, his consciousness rapidly decreased, and it was found on left CAG that there was false aneurysm in the cisternal segment of the left internal carotid artery which has previously been completely healthy. Operation was practiced once again to reinforce the wall of the left internal carotid artery, but the patient died of aggravated meningitis. Autopsy demonstrated a very fragile left internal carotidartery associated with perporation which was surrounded byprominent coagula. Histological examinations indicated that the perforation of the vascular wall had been caused by angitis due to Aspergillus infection. PMID:1242793

    Granuloma formation is usually regarded as a means of defending the host from persistent irritants of either exogenous or endogenous origin. Noninfectious granulomatous disorders of the skin encompass a challenging group of diseases owing to their clinical and histologic overlap. Drug reactions characterized by a granulomatous reaction pattern are rare, and defined by a predominance of histiocytes in the inflammatory infiltrate. This review summarizes current knowledge on the various types of granulomatous drug eruptions, focusing on the 4 major types: interstitial granulomatous drug reaction, drug-induced accelerated rheumatoid nodulosis, drug-induced granuloma annulare, and drug-induced sarcoidosis.

    Idiopathic granulomatous mastitis (IGM) is a rare localized granulomatosis of unknown aetiology that usually affects women of childbearing age. It often mimics breast carcinoma or abscess. Histopathologic evaluation and elimination of the others aetiologies of granuloma play a crucial role in the diagnosis. Its etiopathogeny remains poorly understood, but Corynebacteria might be involved. The disease course is usually protracted, with a significant impact on quality of life. The management of IGM remains controversial, but corticosteroids are usually the first-line treatment. PMID:22981187

    The case history is detailed of a 55-year-old woman who was investigated for persistent pyrexia and anaemia. A liver biopsy specimen showed an unusual lesion of the small intrahepatic arteries. Many of these vessels showed circumferential replacement of their adventitial coat by a non-caseating granuloma whilst others showed localized granulomata focally interrupting the adventitial coat. The medial and intimal coats of the affected arteries were normal. This was an intrahepatic granulomatous arteriopathy of unknown origin. The patient responded promptly and completely to steroid therapy. ImagesFig. 1Fig. 2 PMID:5648674

    Granulomatous interstitial nephritis (GIN) is a rare entity detected in ∼0.5–0.9% of all renal biopsies. GIN has been linked to several antibiotics such as cephalosporins, vancomycin, nitrofurantoin and ciprofloxacin. It is also associated with NSAIDs and granulomatous disorders such as sarcoidosis, tuberculosis, fungal infections, and granulomatosis with polyangiitis. Renal biopsy is critical in establishing this diagnosis, and the extent of tubular atrophy and interstitial fibrosis may aid in determining prognosis. Retrospective data and clinical experience suggest that removal of the offending agent in conjunction with corticosteroid therapy often results in improvement in renal function. We describe a patient with a history of multiple spinal surgeries complicated by wound infection who presented with confusion and rash with subsequent development of acute kidney injury. Urinalysis demonstrated pyuria and eosinophiluria, and renal biopsy revealed acute interstitial nephritis with granulomas. These findings were attributed to doxycycline treatment of his wound infection. This review explores the clinical associations, presentation, diagnosis, and treatment of this uncommon cause of acute kidney injury. PMID:26413275

    Background: Chronic granulomatous disease (CGD) is an uncommon primary immunodeficiency that can be inherited in an X-linked (XL) or an autosomal recessive (AR) manner. We reviewed our large, single-center US experience with CGD. Methods: We reviewed 27 patients at Ann & Robert H. Lurie Children’s Hospital of Chicago from March 1985 to November 2013. Fisher exact test was used to compare differences in categorical variables, and Student t test was used to compare means for continuous variables. Serious infections were defined as those requiring intravenous antibiotics or hospitalization. Results: There were 23 males and 4 females; 19 were XL and 8 were AR. The average age at diagnosis was 3.0 years; 2.1 years for XL and 5.3 years for AR inheritance (P = 0.02). There were 128 serious infections. The most frequent infectious agents were Staphylococcus aureus (n = 13), Serratia (n = 11), Klebsiella (n = 7), Aspergillus (n = 6) and Burkholderia (n = 4). The most common serious infections were pneumonia (n = 38), abscess (n = 32) and lymphadenitis (n = 29). Thirteen patients had granulomatous complications. Five patients were below the 5th percentile for height and 4 were below the 5th percentile for weight. Average length of follow-up after diagnosis was 10.1 years. Twenty-four patients were compliant and maintained on interferon-γ, trimethoprim-sulfamethoxazole and an azole. The serious infection rate was 0.62 per patient-year. Twenty-three patients are alive (1 was lost to follow-up). Conclusions: We present a large, single-center US experience with CGD. Twenty-three of 27 patients are alive after 3276 patient-months of follow-up (1 has been lost to follow-up), and our serious infection rate was 0.62 per patient-year. PMID:26181896

    Chronic Granulomatous Disease (CGD) is an inherited immunodeficiency disorder characterized by defective functioning of NADPH oxidase enzyme in the phagocytes. This leads to recurrent infections by catalase positive organisms and later, granuloma formation in multiple organs. This condition usually presents in the age group of 2-5 y and is uncommon in neonates. In this case report, we describe a rare case of CGD in a 40-day-old male child who initially presented with a history of erythematous pustular rash on left forearm and refusal to feeds. He remained unresponsive to regular antibiotics. CT chest and abdomen revealed multiple ill-defined lesions suggestive of granulomas or developing abscesses. Immunodeficiency workup showed negative Nitroblue Tetrazolium test and positive Dihydrorhodamine test (flow cytometry). A diagnosis of CGD was then made and treated accordingly. The aim of this report is to highlight the fact that although it is rare for CGD to present at such an early age, but in a neonate with multiple granulomas or abscesses, it should be considered as a differential and worked up accordingly. Early diagnosis and treatment can significantly improve the prognosis. PMID:26155526

    Chronic granulomatous disease (CGD) is the most common symptomatic phagocytic defect. It is caused by mutations in genes encoding protein subunits of the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex. CGD is characterized by a defective intracellular killing of phagocytosed organisms due to a defective oxidative burst in the neutrophils and macrophages. It is inherited in either X-linked recessive or autosomal recessive pattern. Staphylococcus aureus and Aspergillus species are the most common organisms reported. Infections with Burkholderia, Serratia, and Nocardia warrant a screen for CGD. Suppurative lymphadenitis, cutaneous abscesses, pneumonia and diarrhea constitute the most common problems in children with CGD. A small percentage of children develop autoimmune manifestations (e.g., rheumatoid arthritis, systemic lupus erythematosus, colitis, autoimmune hepatitis) and warrant immunosuppression. X-linked carriers of CGD are at an increased risk of developing autoimmune diseases. Nitroblue-tetrazolium dye reduction test and dihydro-rhodamine assay by flow cytometry are the screening tests for this disorder. While most children do well on long term antibiotic and antifungal prophylaxis, those with severe forms warrant hematopoietic stem cell transplant. The role of regular interferon-γ injections is debatable. Evidence for white cell transfusions is sparse, and gene therapy is under trial.This current review highlights various aspects and studies in CGD. X-linked form of CGD has been noted to carry a poorer prognosis compared to autosomal recessive variants. However, recent evidence suggests that outcome in CGD is determined by the amount of residual NADPH oxidase activity irrespective of mode of inheritance. PMID:26865172

    Allergic rhinitis is a very frequent disease with a prevalence of 15-20%. Symptoms are most pronounced in young people while, for some unknown reason, the elderly become clinically hyposensitized. Pollen is the cause of seasonal allergic rhinitis, and house dust mite and animals are the main causes of perennial allergic rhinitis. Histamine is the main cause of sneezing and hypersecretion, while other mediators probably also play a role in nasal blockage. In polyposis, a local denervation is an important cause of vascular leakage, edema and polyp formation. Antihistamines have a positive effect on sneezing and hypersecretion, but not on blockage. As they have a quick onset of action they are useful in patients with mild and occasional symptoms. A nasal steroid is preferable in patients with persistent symptoms, since it is more effective on all nasal symptoms. Short-term use of a systemic steroid can be a valuable adjunct to topical treatment, especially in nasal polyposis, when there is a temporary failure of topical treatment in a blocked nose. A nasal vasoconstrictor can be added for short-term treatment, and an ipratropium spray can be beneficial in perennial non-allergic rhinitis, when watery secretion is the dominant symptom. Immunotherapy can be added in allergic rhinitis, when pharmacotherapy is insufficient. This chapter is based on the author's personal experience with allergic rhinitis, as a patient, a doctor and a researcher. Therefore, it is not a balanced review and the references will be highly selected as they largely consist of the author's own publications. As the text is mainly based on personal research, steroids are described in detail, while, with regard to immunotherapy, the reader is referred to another chapter. In addition to allergic rhinitis, nasal polyposis will be described. It was formerly believed to be an allergic disease, but we now know that it is not.

    Gallbladder granulomas are exceedingly rare, reported in association with tuberculosis or sarcoidosis. Here we report a case of gallbladder granulomatous cholecystitis occurring in the context of sarcoidosis. A 70-years old man presented with abdominal pain, nausea and vomiting. The medical history revealed sarcoidosis diagnosed more than 20-years previously. 2-years previously the patient showed renal lithiasis, hypercalcemia and, increased angiotensin converting enzyme. The imaging features suggested thoraco-abdominal sarcoidosis. Prednisone was given at 1.2 mg/kg/day initially, than decreased, being at 2.5 mg/day at present. The ultrasound examination showed gallbladder lithiasis. A cholecystectomy was performed. Microscopy showed subacute and chronic cholecystitis with several epithelioid and giant cell granulomas some of them perineural. In conclusion, we report a case of granulomatous cholecystitis occurring in the course of treated sarcoidosis. The perineural location of granulomas may give further insights into the pathogenesis of gallbladder dysmotility. PMID:27162601

    Interstitial granulomatous dermatitis with arthritis is a rare dermatologic disorder seen in patients suffering from diseases in which circulating immune complexes occur. The typical cutaneous signs are linear cords usually located on the lateral aspect of the trunk. The characteristic, although not specific, histology reveals a dense diffuse infiltrate composed mostly of histiocytes, accompanied by neutrophils and eosinophils, and degenerated collagen surrounded by palisades of histiocytes. We discuss this disorder and its differential diagnosis. PMID:10743580

    2016-01-01

    Introduction Granulomatous prostatitis is a rare inflammatory condition of the prostate. Granulomatous prostatitis is important because, it mimics prostatic carcinoma clinically and hence the diagnosis can be made only by histopathological examination. Aim To study the histomorphological features and to know the prevalence of granulomatous prostatitis. Materials and Methods Histopathological records of 1,203 prostatic specimens received in the Department of the Pathology over a period of five years (June 2009 – June 2014). Seventeen cases of histopathologically, diagnosed granulomatous prostatitis were retrieved and reterospective data was collected from the patient’s records. Results Out of 17 cases of granulomatous prostatitis, we encountered 9 cases of non-specific granulomatous prostatitis, 5 cases of xanthogranulomatous prostatitis and 3 cases of specific tubercular prostatitis. The common age ranged from 51-75 years (mean 63 years) with mean PSA level of 15.8ng/ml. Six patients showed focal hypoechoic areas on TRUS and 11 cases revealed hard and fixed nodule on DRE. Conclusion Non-specific granulomatous prostatitis is the most common type of granulomatous prostatitis. There is no specific pattern of clinical, biochemical and ultrasound findings that allows the diagnosis of granulomatous prostatitis or differentiates it from prostatic carcinoma. Hence, histomorphological diagnosis is the gold standard in differentiating various prostatic lesions. PMID:27014642

    The terms "palisaded neutrophilic and granulomatous dermatitis," "interstitial granulomatous dermatitis," and the subset "interstitial granulomatous drug reaction" are a source of confusion. There exists substantial overlap among the entities with few strict distinguishing features. We review the literature and highlight areas of distinction and overlap, and propose a streamlined diagnostic workup for patients presenting with this cutaneous reaction pattern. Because the systemic disease associations and requisite workup are similar, and the etiopathogenesis is poorly understood but likely similar among these entities, we propose the simplified unifying term "reactive granulomatous dermatitis" to encompass these entities.

    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

    Among the atopic disorders, allergic rhinitis is the most prevalent. Patients who suffer from allergic rhinitis sustain significant morbidity and loss of productivity. Cardinal symptoms include nasal congestion, rhinorrhea, sneezing, and nasal itching, although multiple related symptoms may occur. Causes should be ruled out with a thorough history and physical examination, with particular attention to red flag or atypical symptoms. Skin testing or serum sampling can confirm diagnosis and also guide therapy. Therapy is multimodal, tailored to a particular patient's symptom burden and quality of life. PMID:27545735

    Granulomatous interstitial nephritis has been observed in <1% of native renal biopsies. Here, we describe two patients with granulomatous interstitial nephritis in relation to Crohn's disease. Circulating helper and cytotoxic T cells were highly activated, and both cell types predominated in the interstitial infiltrate, indicating a cellular autoimmune response. After immunosuppressive treatment, renal function either improved or stabilized in both patients. In conclusion, granulomatous interstitial nephritis is a genuine extraintestinal manifestation of Crohn's disease, the treatment of which should include immunosuppressive agents. PMID:27478596

    A 45-year-old male presented with a 6 month history of an enlarging smooth, erythematous plaque over the central part of his face. Mild erythema of both eyes was present. Sarcoidosis, Hansen disease, lupus vulgaris, cutaneous leishmaniasis, pseudolymphoma, foreign body granuloma, granuloma faciale, discoid lupus erythematosus, and granulomatous rosacea were considered in the differential diagnosis. CBC, urinalysis, renal function tests, liver function tests, serum electrolytes, and blood sugar were all normal. Chest X-ray and ECG revealed no abnormality. Serology for syphilis and HIV, and mantoux test were negative. Slit-skin smear, tissue smear and culture for AFB and fungi were negative. Skin biopsy revealed multiple non-caseating epitheloid granulomas around the pilosebaceous unit suggestive of granulomatous rosacea. Granulomatous rosacea, a rare entity comprising only about 10 percent of cases of rosacea can mimic many granulomatous conditions both clinically and histologically making the diagnosis an enigma. It usually presents as yellowish brown-red discrete papules on the face; non-caseating epithelioid granulomas are seen on histology examination. We herein report the case because it presented in atypical fashion, as a solitary indurated plaque on the nose, likely representing Morbihan's disease or solid persistent facial edema of rosacea (rosacea lymphedema).

    Extrinsic allergic alveolitis and pulmonary sarcoidosis are granulomatous diseases of the lung for which clinical presentation and anatomic site of granuloma formation differ. Extrinsic allergic alveolitis is caused by inhaled antigens, whereas the nature and source of the inciting antigen in sarcoidosis is unknown. To test the hypothesis that the route via which antigen is introduced to the lung contributes to the clinicopathological presentation of pulmonary granulomatous disease, rats immunized with intravenous (i.v.) Corynebacterium parvum were challenged after 2 weeks with either intratracheal (i.t.) or i.v. C. parvum. The granulomatous inflammation elicited by i.t. challenge predominantly involved alveolar spaces and histologically simulated extrinsic allergic alveolitis. In contrast, the inflammation induced by i.v. challenge was characterized by granulomatous angiitis and interstitial inflammation simulating sarcoidosis. Elevations of leukocyte counts and TNF levels in bronchoalveolar fluid, which reflect inflammation in the intra-alveolar compartment, were much more pronounced after i.t. than after i.v. challenge. Tumor necrosis factor, interleukin-6, CC chemokine, CXC chemokine, and adhesion molecule mRNA and protein expression occurred in each model. In conclusion, i.t. or i.v. challenge with C. parvum in sensitized rats caused pulmonary granulomatous inflammation that was histologically similar to human extrinsic allergic alveolitis and sarcoidosis, respectively. Although the soluble and cellular mediators of granulomatous inflammation were qualitatively similar in both disease models, the differing anatomic source of the same antigenic challenge was responsible for differing clinicopathological presentations.

  16. Interstitial granulomatous drug reaction with a histological pattern of interstitial granulomatous dermatitis.

    The interstitial granulomatous drug reaction (IGDR) is a novel drug-associated entity, characterized by violaceous plaques with a predilection for skin fold areas. Light microscopically, it resembles the incipient diffuse interstitial phase of granuloma annulare. Differentiating light microscopic features include the absence of complete collagen necrobiosis, the presence of interface dermatitis, and variable lymphoid atypia. The lack of vasculitis rules out the extravascular necrotizing granuloma (Winkelmann granuloma) associated with systemic disease. The differential diagnosis with interstitial granulomatous dermatitis with arthritis as defined by Ackerman et al. has not been studied until now. Our aim was to determine the histologic criteria allowing us to differentiate IGDR without interface dermatitis and lymphoid atypia from interstitial granulomatous dermatitis. We report three patients with IGDR triggered, in two cases by respectively angiotensin convertin enzyme (ACE) inhibitors and furosemide, and in one case by the association of an ACE inhibitor, furosemide, and fluindione. Histologic examination showed a histological pattern of interstitial granulomatous dermatitis. We found a dense, diffuse histiocytic infiltrate distributed interstitially and in palisaded array within the reticular dermis. Eosinophils and some neutrophils were scattered throughout the infiltrate. In some tiny foci, enveloped by histiocytes, thick collagen bundles associated with basophilic nuclear debris or "flame figures" were seen. Vasculitis, interface dermatitis, or lymphoid atypia were absent. Our study allowed us to expand the histological spectrum of IGDR including a histological pattern similar to interstitial granulomatous dermatitis. The lack of degenerated collagen could be a subtle clue in favor of interstitial granulomatous dermatitis triggered by a drug. PMID:11481519

    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.

Retrospective review of imaging data of 10 patients with biopsy proven granulomatous mastitis. The patients were divided into 3 groups according to their initial imaging presentation. Temporal evolution of imaging findings was observed separately for each group. Ratios, proportions, and percentages were used for data analysis. Results. Upon initial presentation, 75% of women who underwent mammogram showed an area of mass like architectural distortion. 25% demonstrated focal asymmetry. Complex cystic lesion was seen 40%. Multiple abscesses with sinus tract formation tracking into surrounding tissues were seen in 2 cases. Four out of 10 patients presented as edematous changes. Three out of this group progressed to develop complex cystic lesions/abscess formation. 25% presenting with complex cystic lesions or abscess at presentation showed spontaneous resolution. The remainder needed surgical treatment. The patients with abscess formation and sinus tract formation needed surgical management. Conclusion. Initial imaging findings in granulomatous mastitis can be variable but the eventual course and outcome is similar in most patients with surgical management required in most cases. PMID:27051554

    Chronic granulomatous mastitis is known as a benign and relatively rare disorder that is often difficult to differentiate from breast carcinoma. We highlight the case of a 34-year-old woman who had recurrent episodes of right breast swelling and abscess for 8 years. These were proven to be chronic granulomatous mastitis by tissue biopsies on 3 different occasions. Her condition improved on similar courses of antibiotics and high-dose prednisolone. However, she subsequently developed progressive loss of vision due to an orbital tumour. She then underwent a craniotomy and left orbital decompression with excision of the tumour, which proved to be a metastatic carcinoma. A trucut biopsy of the right breast was then done and showed features consistent with an infiltrating ductal carcinoma. This case illustrates the possibility that chronic granulomatous mastitis could be a precursor for malignancy and the difficulty in differentiating one from the other. The possible mechanisms of development and the implications for future management are also discussed. PMID:22973142

    Palisaded neutrophilic granulomatous dermatitis (PNGD) is an entity that has not been clearly defined either clinically or histopathologically. It is seen in patients with rheumatoid arthritis and other connective tissue diseases. In the past, many cases of PNGD have been described under several different names including palisaded neutrophilic and granulomatous dermatitis, linear subcutaneous bands, interstitial granulomatous dermatitis with cutaneous cords and arthritis, rheumatoid papules, and Churg-Strauss granuloma. We report 7 additional cases of PNGD. Clinically, 6 patients presented with erythematous to violaceous plaques, papules, and nodules on multiple body sites; one presented with subcutaneous linear bands on the shoulder. Five had rheumatoid arthritis; one had adult-onset Still's disease; and one showed clinical signs of rheumatoid arthritis, although serologically the rheumatoid factor was negative. On histologic examination, a spectrum of changes was observed ranging from urticaria-like infiltrates to leukocytoclastic vasculitis and granuloma annulare with neutrophils. We report these cases to expand the histologic spectrum of this entity and to further delineate the different forms of clinical presentation. PMID:12140472

    We present four cases of cerebral amebae infection treated at our neurosurgical department. Patient 1 was a 12-year-old male with skin lesions of 2 years' progression involving the midface. He received a corticosteroid course, and, after that, he presented a right body hemiparesis. Patient 2 was a 5-year-old male, with a past surgical history of fibula fracture and osteomyelitis of 1-year evolution, associated with lesions of the surrounding skin that presented with partial seizures. Patient 3 was a 3-year-old female who presented with a stroke-like episode and with partial seizures. Patient 4 was a 6-year-old male who had ulcerative lesions in the face of 1-year evolution. After a corticosteroid course, he presented with right-body hemiparesis. All patients were human immunodeficiency virus-negative and died 1 month or less after surgery because of progressive evolution of the disease. Histopathology revealed granulomatous amebic encephalitis. All patients revealed infection from Balamuthia mandrillaris (Leptomyxiidae). Treatment consisting of pentamidine, clarithromycin, fluconazole, and 5-fluorocytosine was ineffective. Although extremely uncommon, granulomatous amebic encephalitis should be considered in the differential diagnosis of cerebral lesions while nonspecific, associated granulomatous skin lesions support the diagnosis of amebiasis.

    Granulomatous reactions to tattoo ink are most commonly associated with mercury sulfide, a component of red pigments. Treatment options show limited results. Allopurinol, an inhibitor of xanthine oxidase, has been reported as a successful alternative treatment to granulomatous disorders, such as sarcoidosis and granulomatous reactions to fillers and tattoos. We report a case of granulomatous reaction to red tattoo pigment treated with allopurinol for 6 months. Good clinical improvement could be noticed during this time. Two months after we stopped the treatment, the lesion recurred. Allopurinol emerges as an important drug for the management of granulomatous reactions caused by tattoo pigments. Based on the significant clinical improvement noticed during its use, we recommend new studies to elucidate all the potential benefits of the use of allopurinol for the treatment of granulomatous reactions to tattoo ink.

    The prevalence of childhood allergic diseases, such as allergic asthma, allergic rhinitis, and atopic dermatitis, has increased exponentially. In Singapore, the prevalence of asthma at all ages exceeds 20%, and around 50% of Singaporean children show features of an underlying allergy. The exact environmental causes for the increase of allergic diseases have not yet been identified, but most researchers agree that a decreased bacterial load in young children may be one of the reasons for the increase. However, the causes of allergy are multiple, and the development of an allergic disease is the result of complex interactions between genetic constitution and environmental factors. In this review article, different aspects of allergic sensitization are covered, including prenatal and postnatal sensitization. The phenomenon of the "allergic march" (switching from one clinical expression of allergy to another) and its underlying mechanisms are discussed. The last part of this review article is on prevention and treatment of allergic diseases, including the role of bacterial products (probiotics, prebiotics, and synbiotics) and the role of immunotherapy, including sublingual immunotherapy.

    Aim To investigate and compare the presentation of granulomatous lesions in optical coherence tomography (OCT) images and compare this to previous studies of nonmelanoma skin tumors. Methods Two patients with granulomas, tophi and granuloma annulare (GA), respectively, were photographed digitally, OCT-scanned and biopsied in the said order. Normal skin was OCT-scanned for comparison, but not biopsied. The OCT images from each lesion were compared with their histologic images as well as with OCT images with similar characteristics obtained from nonmelanoma skin tumors. Results The OCT images of the tophi showed hyperreflective, rounded cloud-like structures in dermis, their upper part sharply delineated by a hyporeflective fringe. The deeper areas appeared blurred. The crystalline structures were delineated by a hyporeflective fringe. OCT images of GA showed two different structures in dermis: a hyporeflective rounded one, and one that was lobulated and wing-like. Conclusion Granulomatous tissue surrounding urate deposits appeared as a clear hyporeflective fringe surrounding a light, hyperreflective area. The urate crystals appeared as hyperreflective areas, shielding the deeper part of dermis, meaning OCT could only visualize the upper part of the lesions. The lobulated, wing-like structure in GA may resemble diffuse GA or a dense lymphocytic infiltrate as seen on histology. The rounded structure in GA may represent an actual granuloma or either diffuse GA or a dense lymphocytic infiltrate as described above. This case suggests that OCT images granulomatous tissue as absorbent, hyporeflective areas, and urate crystals appear as reflective areas, obscuring the underlying tissue. In GA a new image shape looking like a wing has been found. The frequency, specificity and sensitivity of this new pattern in OCT imaging will require further studies. PMID:22493578

    Allergic disease development is affected by both genes and the environment, and epigenetic mechanisms are hypothesized to mediate these environmental effects. 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

    Granulomatous arteritis characterizes the pathology of giant cell arteritis, granulomatous aortitis, and intracerebral varicella zoster virus (VZV) vasculopathy. Because intracerebral VZV vasculopathy and giant cell arteritis are strongly associated with productive VZV infection in cerebral and temporal arteries, respectively, we evaluated human aortas for VZV antigen and VZV DNA. Using 3 different anti-VZV antibodies, we identified VZV antigen in 11 of 11 aortas with pathologically verified granulomatous arteritis, in 1 of 1 cases of nongranulomatous arteritis, and in 5 of 18 control aortas (28%) obtained at autopsy. The presence of VZV antigen in granulomatous aortitis was highly significant (P = .0001) as compared to control aortas, in which VZV antigen was never associated with pathology, indicating subclinical reactivation. VZV DNA was found in most aortas containing VZV antigen. The frequent clinical, radiological, and pathological aortic involvement in patients with giant cell arteritis correlates with the significant detection of VZV in granulomatous aortitis.

    Abstract Idiopathic granulomatous hypophysitis (IGH) is a rare inflammatory disease of the pituitary that commonly presents with enlargement of the pituitary gland. Clinically and radiologically, IGH is a rare sellar entity easily to be misdiagnosed as a pituitary adenoma. Through such a case, we aim to present this rarity and emphasize the importance to correctly diagnose confusing pituitary lesions comprehensively by clinical presentations, radiological signs, and biopsy. We present an uncommon case of IGH in a 19-year-old man. The patient was admitted to the hospital with severe headache, vomiting, and vision's sharp decline. Magnetic resonance imaging showed a sellar lesion with obvious cystic change and ring enhancement. The disease course including diagnosis and treatment was presented and analyzed in detail. The pertinent literature is reviewed regarding this uncommon entity. The patient underwent surgical exploration and partial resection via the transsphenoidal approach. The pathologic findings suggested IGH giving no significant evidences of systemic granulomatous disease and venereal disease. Large dose methylprednisolone was then used. The pituitary function recovered, but there was no apparent improvement of his vision. IGH is a rarely occurred inflammatory disease of unknown etiology. It is difficult to diagnose preoperatively and is often misdiagnosed. Although rare, IGH should be kept in mind in terms of differential diagnosis of sellar region lesions. PMID:26181544

    Background: Idiopathic granulomatous mastitis (IGM) is an uncommon benign chronic inflammatory breast disease, and erythema nodosum (EN) is an extremely rare systemic manifestation of IGM. Here, we report a rare case of IGM accompanied by EN. Case Report: A 32-year-old patient was admitted to our clinic with a history of a tender mass in the right breast. On physical examination, the right breast contained a hard, tender mass in the lower half with indrawing of the nipple. She had florid EN affecting both legs. She was evaluated with mammography, ultrasound, power Doppler ultrasound, non-enhancing magnetic resonance imaging (MRI), dynamic contrast-enhanced MRI, fine needle aspiration biopsy (FNAB) and excisional biopsy. Time-intensity curves showed a type II pattern on dynamic contrast-enhanced MRI, which has an intermediate probability for malignancy. The FNAB reported a benign cytology suggestive of a granulomatous inflammation, which was also supported by the histopathological findings. A partial mastectomy was performed following medical treatment. There was no recurrence at 1-year follow-up. Conclusion: IGM should be considered in the differential diagnosis of EN. Although histopathological examination remains the only method for the definite diagnosis of IGM, MRI can be helpful in the diagnosis or differentiation of benign lesions from malignant ones.

    Allergic asthma refers to a chronic reversible bronchoconstriction influenced by an allergic trigger, leading to symptoms of cough, wheezing, shortness of breath, and chest tightness. Allergic bronchopulmonary aspergillosis is a complex hypersensitivity reaction, often in patients with asthma or cystic fibrosis, occurring when bronchi become colonized by Aspergillus species. The clinical picture is dominated by asthma complicated by recurrent episodes of bronchial obstruction, fever, malaise, mucus production, and peripheral blood eosinophilia. Hypersensitivity pneumonitis is a syndrome associated with lung inflammation from the inhalation of airborne antigens, such as molds and dust. PMID:27545731

    Allergies are generally thought to be a detrimental outcome of a mistargeted immune response that evolved to provide immunity to macroparasites. Here we present arguments to suggest that allergic immunity has an important role in host defence against noxious environmental substances, including venoms, haematophagous fluids, environmental xenobiotics and irritants. We argue that appropriately targeted allergic reactions are beneficial, although they can become detrimental when excessive. Furthermore, we suggest that allergic hypersensitivity evolved to elicit anticipatory responses and to promote avoidance of suboptimal environments. PMID:22538607

    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

    The allergic diseases are complex phenotypes for which a strong genetic basis has been firmly established. Genome-wide association studies (GWAS) has been widely employed in the field of allergic disease, and to date significant associations have been published for nearly 100 asthma genes/loci, in addition to multiple genes/loci for AD, AR and IgE levels, for which the overwhelming number of candidates are novel and have given a new appreciation for the role of innate as well as adaptive immune-response genes in allergic disease. A major outcome of GWAS in allergic disease has been the formation of national and international collaborations leading to consortia meta-analyses, and an appreciation for the specificity of genetic associations to sub-phenotypes of allergic disease. Molecular genetics has undergone a technological revolution, leading to next generation sequencing (NGS) strategies that are increasingly employed to hone in on the causal variants associated with allergic diseases. Unmet needs in the field include the inclusion of ethnically and racially diverse cohorts, and strategies for managing ‘big data’ that is an outcome of technological advances such as sequencing.

    Idiopathic granulomatous mastitis (IGM) is a rare chronic inflammatory condition of the breast which although benign can mimic carcinoma. Establishing a diagnosis can be challenging and requires a high index of suspicion with exclusion of infective and autoimmune breast diseases. IGM is characterized histologically by noncaseating granulomas which are of a lobulo-centric pattern and often associated with microabscess formation. Management of confirmed cases remains controversial with proponents of initial surgical or medical therapies - each has its associated problems which can be worse than the original symptoms of IGM. However, many patients require more than one modality of treatment to completely resolve IGM lesions and careful judgment is necessary to ensure optimal type and sequencing of treatments.

    Chronic Granulomatous Disease (CGD) is a primary immunodeficiency caused by abnormities in the NADPH Oxidase that is involved in the respiratory burst responsible for initiating the killing of microbes ingested by phagocytic cells. The hallmark of CGD is recurrent infection but the inflammatory complications can prove difficult to treat. New insights into the mechanisms responsible for the inflammatory complications have led to new therapies. The treatment of CGD colitis with an anti-tumour necrosis alpha agent has been shown to be successful but associated with significant infectious complications. Haematopoietic stem cell transplants offer the possibility of cure for those with ether a matched or unrelated donor transplant, with results of the latter improving significantly over recent years. Gene Therapy offers the promise of cure without the need for a transplant but better vectors are required. PMID:25264161

    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.

    The case of a 20-year-old Japanese man, diagnosed as having autosomal recessive chronic granulomatous disease (CGD), who was being treated with corticosteroids for intractable unclassified colitis, is described. He died from multiple organ failure following disseminated intravascular coagulation secondary to disseminated varicella-zoster virus (VZV) infection. He was diagnosed as an index case of CGD when 2 years old, was inoculated against VZV at the age of 5 years and had had an unremarkable course for 19 years. He was admitted to hospital because of a third episode of recurrent bloody diarrhoea. Clinical remission for each episode was achieved by intravenous corticosteroid therapy. Unclassified colitis associated with CGD was diagnosed based on a colonic biopsy demonstrating characteristic macrophages with lipofuscin deposits. From a treatment viewpoint, idiopathic inflammatory bowel disease (IBD) should be differentiated from secondary IBD occurring in CGD, in which immunosuppressive drugs including corticosteroids, still the mainstay of IBD treatment, should be avoided.

    Albumin lung-scanning agents have a proven high degree of safety, with the only contraindication to their use being allergic hypersensitivity. We have used these agents to investigate the physiologic effects of high G/sub z/ acceleratory forces on pulmonary perfusion using the miniature swine. Multiple doses of human macroaggregated albumin and human-albumin microspheres were given to a miniature swine at various levels of centrifugal acceleration over a 6-wk period. The dosages given were the same per kilogram as those used for routine clinical human studies. The animal subsequently died from a severe granulomatous interstitial pneumonia. The granulomatous lesions suggest that the pathogenesis may have involved a cell-mediated delayed hypersensitivity. This interstitial pneumonia may represent the end point in a chronic hypersensitivity response to the human-albumin lung-scanning agents.

    Phenytoin was introduced in 1938 for the control of seizure disorders and remains widely used today. Since that time, many cases of phenytoin-induced allergic reactions and clinical pulmonary disease have been reported. However, pulmonary vascular pathology from phenytoin use has been only very rarely described. We report a case of phenytoin-associated vasculitis in a 39-year-old African American man presenting with progressive dyspnea and abnormal chest imaging. The importance of reviewing the medication history along with familiarity with the array of drug-associated lung diseases is crucial to recognize and treat pneumotoxicity. PMID:24247101

    This article reviews the history of allergic fungal rhinosinusitis and the clinical, pathologic, and radiographic criteria necessary to establish its diagnosis and differentiate this disease from other types of chronic rhinosinusitis. Allergic fungal rhinosinusitis is a noninvasive fungal form of sinus inflammation characterized by an often times unilateral, expansile process in which the typical allergic "peanut-butter-like" mucin contributes to the formation of nasal polyps, hyposmia/anosmia, and structural changes of the face. IgE sensitization to fungi is a necessary, but not sufficient, pathophysiologic component of the disease process that is also defined by microscopic visualization of mucin-containing fungus and characteristic radiological imaging. This article expounds on these details and others including the key clinical and scientific distinctions of this diagnosis, the pathophysiologic mechanisms beyond IgE-mediated hypersensitivity that must be at play, and areas of current and future research.

It has gained attention over last decade and can affect patients from all countries, ethnic groups and ages, impairing their quality of life, and is frequently associated with conjunctivitis and asthma. Diagnosis is based on clinical history, the demonstration of a positive response to nasal allergen provocation test and/or the detection of nasal sIgE. A positive basophil activation test may support the diagnosis. Recent studies have demonstrated that allergen immunotherapy is an effective immune-modifying treatment, highlighting the importance of early diagnosis. PMID:27083105

    Chronic granulomatous disease (CGD) is a primary immunodeficiency caused by a defect in production of phagocyte-derived reactive oxygen species, which leads to recurrent infections with a characteristic group of pathogens not previously known to include methylotrophs. Methylotrophs are versatile environmental bacteria that can use single-carbon organic compounds as their sole source of energy; they rarely cause disease in immunocompetent persons. We have identified 12 infections with methylotrophs (5 reported here, 7 previously reported) in patients with CGD. Methylotrophs identified were Granulibacter bethesdensis (9 cases), Acidomonas methanolica (2 cases), and Methylobacterium lusitanum (1 case). Two patients in Europe died; the other 10, from North and Central America, recovered after prolonged courses of antimicrobial drug therapy and, for some, surgery. Methylotrophs are emerging as disease-causing organisms in patients with CGD. For all patients, sequencing of the 16S rRNA gene was required for correct diagnosis. Geographic origin of the methylotroph strain may affect clinical management and prognosis. PMID:26886412

    Chronic granulomatous disease (CGD) is a primary immunodeficiency (PID) characterized by the inability of phagocytes to produce reactive oxygen intermediates (ROIs) due to a defect in the NADPH oxidase complex. Recent studies have revealed that ROIs are involved in inflammatory signaling in phagocytes, illuminating the underlying mechanisms of hyper-inflammation in CGD. CGD patients frequently suffer from CGD-associated bowel inflammation, granuloma, and life-threatening infections. Based on the discovery of the regulatory function of ROIs in the immune response, therapeutic methods for excessive inflammation focusing on inflammatory cytokines are being developed for CGD. Although hematopoietic stem cell (HSC) transplantation (HSCT) is a curative therapy for CGD, successful transplants greatly depend on HSC source selection and the degree of matching of potential donors. Gene therapy trials for PID have been performed on over 120 patients with no HLA identical donor for HSCT, and have demonstrated clinical benefits. Genotoxicity in HSC gene therapy trials has expanded our knowledge on the mechanisms of vector-associated clonal expansion of gene-modified cells, which will advance gene therapy development using self-inactivating retrovirus and lentivirus vectors. We will discuss the complications of HSCT for CGD. We will then outline the status of gene therapy approaches in the treatment of CGD. PMID:25748127

    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.

    With the purpose of facilitating clinical studies of this infrequent disease, an expert panel published research criteria for birdshot retinochoroiditis (RCBRC). The aim of our study was to investigate the sensitivity of the exclusion criteria of the RCBRC as applied to all patients seen in our center with a diagnosis of BRC. This was a single center retrospective study involving all patients with an ocular inflammatory disease seen at the Centre for Ophthalmic Specialized Care, Lausanne, Switzerland, between 1995 and 2012. The percentage of patients with a diagnosis of BRC was identified. The exclusion criteria of the RCBRC were applied to all patients and the percentage of patients with absence of keratic precipitates (KPs) and absence of posterior synechiae were calculated. Out of 1,504 new patients, 25 patients (1.66 %; 19 female, 6 male) were diagnosed with BRC and 19 patients had sufficient data to be included in the study (1.26 %, 13 female). All patients were positive for HLA-A29 testing. The sensitivity of the RCBRC with respect to the exclusion criteria applied to our patient cohort was 84.2 % due to the exclusion of three patients showing KPs. Our study supports the motion to re-evaluate the RCBRC, since granulomatous KPs can be present and are more frequent than previously estimated and stringent application of the criteria would lead to a substantial loss of study patients.

    Idiopathic granulomatous hypophysitis (GH) is an uncommon inflammatory disease of the pituitary with impairment of pituitary gland function due to infiltration by lymphocytes, plasma cells and macrophages. We report the case of a 39-year-old woman who presented with worsening of headaches for 1 month and blurring of vision over 5 days. An MRI revealed a homogeneous supra-sellar mass evoking a pituitary tumour with bulky pituitary stalk extending into the left and right cavernous sinuses. Hormonal investigations showed anterior pituitary hormone deficiencies; meanwhile histopathological examination revealed an aspect of hypophysitis. Clinical and radiological remission occurred immediately postglucocorticoid therapy with the addition of a steroid-sparing agent later in view of recurrence of symptoms on glucocorticoid dose reduction. GH has important diagnostic and therapeutic implications, as clinical and radiological features ameliorate via medical treatment. With further understanding and recognition of the disease, we hope to highlight a case of GH, in which signs and symptoms improved after initiation of corticosteroids. PMID:27613264

    Granulomatous mastitis (GM) is a relatively uncommon inflammatory breast lesion with multiple suggested etiologies. Although most GM cases show association with lactation and pregnancy, a minority of cases have been linked to hyperprolactinemia caused by either dopamine antagonist medications or with intracranial lesions, such as pituitary adenoma. The goal of this study is to review the GM cases reported in the literature with a specific emphasis on those cases associated with hyperprolactinemia and prolactinomas and to identify cases of GM seen at the Cleveland Clinic Florida which demonstrate co-occurrences of GM and intracranial lesions. CoPath and Epic data bases at Cleveland Clinic Florida were searched for cases describing inflammatory breast lesions in patients with pituitary pathology. Chart reviews were conducted and pertinent medical history was extracted for case reports. H&E-stained paraffin-embedded sections retrieved from Cleveland Clinic Florida pathology storage were evaluated by light microscopy. Four cases showing a co-occurrence of GM and hyperprolactinemia were consequently identified. A prolactin-secreting pituitary adenoma was present in two of the three GM cases. The third case demonstrated a concomitant craniopharyngioma, which was also associated with a rise in serum prolactin. This phenomenon was presumably attributable to compression, resulting in compromised transport of dopamine to the adenohypophysis and subsequent disinhibition of prolactin secretion by lactotrophs. The fourth patient with GM had a similar history of elevated prolactin. Classical histopathological features of GM were found in all four cases, including noncaseating granulomas, multinucleated giant cells, epithelioid histiocytes, and chronic inflammation. Intriguingly, complete resolution of inflammatory breast lesions along with normalization of prolactin levels occurred following the surgical excision of the craniopharyngioma, suggesting that intracranial lesion

    Idiopathic granulomatous mastitis is a rare inflammatory breast disease of unknown etiology. It manifests as breast mass of 6 cm on average (range 2-10 cm), often in upper outer quadrant of left breast, in another quadrant, right or bilateral breast. Clinical diagnosis by ultrasound or mammography and fine needle aspiration confuses with carcinoma; histopathology (gold standard) confirm the diagnosis after ruling out causes of granulomatous inflammation, mainly tuberculosis. Steroid treatment achieve complete remission, but adverse reactions and relapses after the descent and suspension. Methotrexate or azathioprine is added from the start to maintain remission. We report three cases of idiopathic granulomatous mastitis diagnosis and treatment based on prednisone until clinical improvement and methotrexate as maintenance therapy. Complete remission was obtained in three patients. The rheumatologist knows and handles autoimmune/inflammatory with these drugs, therefore, is suggested the multidisciplinary treatment of this disease with oncologists and gynecologists.

    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.

    Pseudomonas cepacia was recovered from a number of infected sites in three patients with chronic granulomatous disease of childhood. The organisms were identified on the basis of their oxidative utilization of a variety of carbohydrates and their positive beta-galactosidase and oxidase activities. They were resistant to most antimicrobial agents and moderately susceptible to chloramphenicol. Peripheral blood leukocytes isolated from two siblings with chronic granulomatous disease, including one of the patients in this series, failed to kill P. cepacia in vitro. Prolonged prophylactic and antimicrobial therapy may well have played a significant role in the colonization and infection of these patients with P. cepacia. PMID:1176612

    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 human subjects and murine systems have shown that basophils perform nonredundant 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. Furthermore, 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

    Allergic inflammation is associated closely with parasite infection but also asthma and other common allergic diseases. Despite the engagement of similar immunologic pathways, parasitized individuals often show no outward manifestations of allergic disease. In this perspective, we present the thesis that allergic inflammatory responses play a primary role in regulating circadian and environmental inputs involved with tissue homeostasis and metabolic needs. Parasites feed into these pathways and thus engage allergic inflammation to sustain aspects of the parasitic life cycle. In response to parasite infection, an adaptive and regulated immune response is layered on the host effector response, but in the setting of allergy, the effector response remains unregulated, thus leading to the cardinal features of disease. Further understanding of the homeostatic pressures driving allergic inflammation holds promise to further our understanding of human health and the treatment of these common afflictions.

    Granulomatous lung lesions were produced in rats by 5 intravenous or intratracheal injections of the killed BCG suspension as an antigen. On the basis of immunocomplex and cell-mediated immunopathological reactions this condition may be considered as a chronic allergic form of alveolitis. Granulomas were formed along the arteries when the antigen was administered intravenously and along the bronchi after its intratracheal administration. In both cases there were single granulomas in the alveolar septa interstitium. The microcirculatory bed was studied in semithin sections and morphometrically in thick sections after impregnation with an Indian ink and 5% gelatin. The alveolar septa capillaries in control rats were shown to form a network the parameters ow which rather correspond to the "sheet-blow" model (Fung and Sobin, 1969). In chronic allergic alveolitis, a reduction of the capillary network develops at the zone of granulomatous inflammation while in the relatively normal zone a network type of the microcirculatory bed is preformed into the main one with the formation of predominant routes of circulation that provide the blood filling of the heart cavities.

    Business and tourist journeys by air contribute to exposure of the body to multiple environments. The allergic patient, considered rightly to be a sentry of the environment, has many reasons to care about his journeys and to take precautions that are adapted to his case under the impetus of advice and information from his physician and his specialist. Some advice falls within a simple logic that is enough to remember when planning the journey while the others measures must follow a correct preventative strategy for allergy risks as much as those that concern the modalities before leaving as a drive taken on the ground. It is important therefore to know how to give advice and information on the different risks linked to the allergic condition and to the field of allergy and help the patient to orientate his choice of place of the journey, the methods of lodging, of transport and the programme of the journey. The advice should also include the preventative measures as a function of the known pathology under the form of medical equipment before, during the stay and on return. Finally some advice relative to medical equipment for prevention and cure would appear to be judicious. PMID:10524269

    Varicella zoster virus (VZV) causes the common childhood disease chickenpox (varicella), or upon reactivation, the dermatomal vesiculopustular eruption seen in shingles (herpes zoster). The clinical course of herpes zoster in immunocompromised patients is often recurrent, protracted and multidermatomal, and it can result in myelitis, meningoencephalitis, and cerebral or small-vessel vasculopathic or vasculitic changes. Commonly, the vesicular rash settles with aciclovir therapy and does not involve motor neuropathy. We report a 63-year-old man with a prolonged, multidermatomal, nonvesicular rash, and limb paresis secondary to brachioplexitis. PCR for VZV was positive, and the histological results were consistent with granulomatous vasculopathy. Prolonged treatment with valaciclovir was required to resolve the eruption and help improve the patient's motor function. We discuss the problems faced in clinical decision-making about immunosuppressive treatment of granulomatous vasculopathy and motor neuropathy, when any increase in immunosuppressive therapy may increase the likelihood of central nervous system complications.

    The Leishmania granuloma shares some, though not all, properties with that formed following mycobacterial infection. As a simplified, noncaseating granuloma composed of relatively few and largely mononuclear cell populations, it provides a tractable model system to investigate intra-granuloma cellular dynamics, immune regulation, and antimicrobial resistance. Here, the occurrence of granulomatous pathology across the spectrum of leishmaniasis, in humans and animal reservoir hosts, is first described. However, this review focuses on the process of hepatic granuloma formation as studied in rodent models of visceral leishmaniasis, starting from the initial infection of Kupffer cells to the involution of the granuloma after pathogen clearance. It describes how the application of intravital imaging and the use of computational modeling have changed some of our thoughts on granuloma function, and illustrates how host-directed therapies have been used to manipulate granuloma form and function for therapeutic benefit. Where appropriate, lessons that may be equally applicable across the spectrum of granulomatous diseases are highlighted. PMID:26678994

    Blau syndrome is a rare hereditary granulomatous disease presenting in patients of young age with exanthema, granulomatous arthritis and uveitis. Genetic analysis has shown an autosomal dominant inheritance and a number of specific mutations on chromosome 16q in codon 334, of which the most predominant are R334W and R334Q. Blau syndrome exists in Caucasian, Asian and Afro-American families, and de novo mutations have been reported. The estimated minimum incidence in Denmark is 0.05 per 100,000 person-years. Blau syndrome has pathological, clinical and therapeutic features in common with sarcoidosis but rarely involves the lungs or other parenchymatous organs. Discrimination between Blau syndrome and early-onset sarcoidosis should rely on chromosome analysis. PMID:17069723

    Interstitial granulomatous dermatitis is a rare entity characterized by cutaneous linear strands (the "rope sign") and rheumatoid arthritis. In the past years, 12 other cases have been described with variable cutaneous symptoms. All showed similar histological features, resembling those of granuloma annulare or 'palisaded neutrophilic and granulomatous dermatitis', suggesting a wide spectrum for a single entity. A 60-year-old patient presented with erythematous patches with an indurated, violaceous border resembling the "rope sign" on both flanks. The histological investigation revealed dense diffuse interstitial inflammatory infiltrates composed of eosinophils, neutrophils, lymphocytes, macrophages and multinucleated giant cells in the superficial and deep dermis. In the deep dermis, prominent eosinophilic degenerated collagen fibres with surrounding macrophages ('floating sign') occurred. In contrast to most previously described patients, our patient did not have arthralgias. The skin findings cleared following therapy with hydroxychloroquine. PMID:16285183

    Granulomatous reactions to dermal fillers for tissue augmentation is a rare but possible late complication occurring both with permanent (more frequent) and biodegradable or resorbable products. Predictions cannot be made for possible late reactions, sometimes occurring even after 18 years. Although clinical diagnosis seems to be an easy task, the issue is sometimes challenging if cosmetic intervention is denied or not mentioned by the patient or by the referring physician. Identifying the filler is therefore difficult and experts may be called in trials to solve the problem. Histopathology is the best means to obtain the correct diagnosis and to identify the type of filler particles. In fact, the particular configuration of the vacuoles and cystic structures inside the granulomas reflects the shape of the injected implants particles. The clinical and microscopic features, the pathogenesis and the treatment of the granulomatous reactions to dermal fillers for tissue augmentation will be presented and discussed. PMID:18442665

    From the experience above, it may be concluded that corticosteroid therapy in allergic disease has become more effective than ever before. The expected variations in usage of new important pharmacologic agents is seen with special clarity in the use of corticosteroids. The wide acclaim for the "miracle drug of the 1950's", which followed penicillin of the 1940's, soon gave away to anguish about side-effects that threatened to abolish its use entirely in the late 1950's. The 1960's brought alternate day therapy for chronic usage and recognition that short term usage was relatively safe. The 1970's saw proliferation of topically active steroids similar to those so important to the practice of Dermatology in the previous decade. Results in treating asthma and nasal diseases have been excellent and extensive research for adverse effects has been largely unrevealing. PMID:6793795

    Local or systemic injection of peptidoglycan-polysaccharide polymers, which are the primary structural components of cell walls of nearly all bacteria, leads to acute inflammation, which can develop into chronic, spontaneously relapsing, granulomatous inflammation in a number of organs. Evolution into chronic granulomatous inflammation is dependent upon persistence of poorly biodegradable cell wall polymers within tissues, genetically determined host susceptibility, and generation of a T-lymphocyte-mediated immune response. Intraperitoneal injection of peptidoglycan-polysaccharide fragments from group A streptococci or selected intestinal bacteria into susceptible Lewis rats leads to chronic, spontaneously reactivating erosive arthritis and hepatic granulomas. Subserosal (intramural) injection of poorly biodegradable cell wall fragments into the distal intestine of Lewis rats induces chronic, spontaneously relapsing granulomatous enterocolitis with associated arthritis, hepatic granulomas, anemia, and leukocytosis. Chronic inflammation does not occur in T-lymphocyte-deficient rats and is prevented by cyclosporin-A therapy and degradation of peptidoglycan by the muralytic enzyme, mutanolysin. Moreover, resistant Buffalo and Fischer F344 rats, the latter sharing identical MHC antigens with Lewis rats, develop only acute inflammation with no chronic granulomatous response. Peptidoglycan-polysaccharide polymers activate almost every limb of the inflammatory response. Blockade of specific pathways suggests that interleukin-1, transforming growth factor-beta, plasma kallikrein, and T lymphocytes are dominant mediators of peptidoglycan-polysaccharide-induced arthritis, hepatic granulomas, and enterocolitis. Because of the similarity of immune mechanisms of these rat models to human disease, bacterial cell wall-induced inflammation provides unique opportunities to study pathogenic mechanisms of granuloma formation in response to ubiquitous microbial agents and to test

    Shortly after removal of an engorged tick from the left ear, a 4-year-old Greyhound was referred for evaluation of fever and a rapidly enlarging mass in the region of the left submandibular lymph node. Histopathologic evaluation of the lymph node resulted in a diagnosis of severe granulomatous lymphadenitis. An 11-year-old mixed-breed dog was referred for evaluation of a 6-week history of serous nasal discharge. Histologic examination of a surgical biopsy from a nasal mass indicated multifocal granulomatous inflammation with fibrosis. Serum samples obtained from both dogs were reactive by immunofluorescent assay to Bartonella vinsonii subsp. berkhoffii antigens (reciprocal titers of 128). Although Bartonella organisms were not isolated by lysis centrifugation blood culture, Bartonella DNA was amplified from tissue samples obtained from each dog (lymph node biopsy from dog 1 and nasal biopsy from dog 2) using primers that amplify a portion of the 16S rRNA gene followed by Southern blot hybridization using a genus-specific probe. Additionally, restriction fragment length polymorphism (RFLP) analysis of a Bartonella-specific citrate synthase gene product obtained from dog 2 resulted in a restriction pattern identical to B. vinsonii subsp. berkhoffii. This is the 1st report of granulomatous disease in dogs associated with Bartonella infection. PMID:10668815

    Chronic granulomatous disease in males is familial and its transmission is is usually clearly x-linked. The mode of inheritance in females with the syndrome is unknown and the carrier state difficult to identify. Defective polymorphonuclear leukocyte bactericidal activity in this disease is associated with an absence of the respiratory burst generated in stimulated phagocytes and may be detected by the chemiluminescence assay. Polymorphonuclear leukocytes from three of four females with chronic granulomatous disease had extremely low chemiluminescence production, their asymptomatic mothers had intermediate values, and their fathers were normal. Polymorphonuclear neutrophils of two affected males in these kinships generated no chemiluminescence, whereas two of seven female relatives had intermediate values, and all nonaffected males had normal values. In the three families in which leukocytes were studied by nitroblue tetrazolium reduction, two populations of neutrophils were demonstrated for the female patients and/or their mothers. The wide phenotypic variability for clinical disease, evidence of two leukocyte populations in the patients or their mothers, and low but detectable leukocyte chemiluminescence in the affected females is consistent with the Lyon hypothesis of x-chromosome inactivation in these families. The findings suggest an x-linked inheritance in these females with chronic granulomatous disease. Images PMID:7400319

    Purpose The acute host response to histoplasma capsulatum infection varies according to exposure and susceptibility. Late sequelae include calcifications in the lung, thoracic lymphatics, and spleen. Determinants of calcified granuloma formation are poorly studied and may differ from those affecting acute response. We examined the occupational associations and familial aggregation of radiographic calcified granulomatous disease to characterize the determinants of calcified granuloma formation. Methods We analyzed prospectively collected cross-sectional data including computed tomograms from 872 adult members of the Old Order Amish of Lancaster County. Results Granulomas were present in 71 % of participants. Granulomas were present in the lung of 57 % of participants, in the hilar or mediastinal lymph nodes of 55 % of participants, and in the spleen of 29 % of participants. No significant differences were observed in the presence of granulomas between men and women. Each year of age was associated with 4 % higher odds of splenic calcifications, and a primary occupation of farming was associated with an 84 % higher odds of splenic calcifications. A compelling pattern of familial aggregation was not observed. Conclusions Calcified granulomatous disease does not appear to aggregate in families. Determinants influencing patterns of granulomatous disease include occupation, age, and geographic location. PMID:25038755

    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

    Skin findings in childhood sarcoidosis vary greatly, but only a few occurrences have been published in which the histopathology has been characterized well. We describe a child with sarcoidosis in whom the cutaneous findings were atypical, resembling granuloma annulare. Histologic examination of these cutaneous lesions, however, revealed areas of sarcoid-like epithelioid cell granulomas, a palisading granulomatous process with features of granuloma annulare, as well as palisading neutrophilic and granulomatous dermatitis and interstitial granulomatous dermatitis. This underscores the variability of skin findings in childhood sarcoidosis--even within the same patient--and suggests that sarcoidosis should be considered in the differential diagnosis of children initially diagnosed with granulomatous skin lesions, such as granuloma annulare, palisading neutrophilic, and granulomatous dermatitis or interstitial granulomatous dermatitis, who demonstrate associated signs of systemic disease.

    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.

    Paralleling the overall trend in allergic diseases, Eosinophilic Esophagitis is rapidly increasing in incidence. It is associated with food antigen-triggered, eosinophil-predominant inflammation and the pathogenic mechanisms have many similarities to other chronic atopic diseases, such as eczema and allergic asthma. Studies in animal models and from patients over the last 15 years have suggested that allergic sensitization leads to food-specific IgE and T-helper lymphocyte type 2 cells, both of which appear to contribute to the pathogenesis along with basophils, mast cells, and antigen-presenting cells. This review will outline our current understandings of the allergic mechanisms that drive eosinophilic esophagitis, drawing from clinical and translational studies in humans as well as experimental animal models.

    Granulomatous diseases have a varied etiology that includes autoimmune, infectious, idiopathic, and hereditary causes. The unifying factor in these diseases is the formation of granulomas, which histologically are mononuclear inflammatory cells or macrophages surrounded by lymphocytes. Granulomatous diseases often have systemic manifestations that affect organs throughout the body. Granulomatous diseases with head and neck manifestations include granulomatosis with polyangiitis, Churg-Strauss syndrome, Behçet disease, chronic granulomatous disease, and sarcoidosis. Infectious causes include tuberculosis, cat-scratch disease, syphilis, leprosy, actinomycosis, rhinoscleroma, and fungal infections. In the head and neck, granulomatous disease may affect the orbits, sinonasal cavities, salivary glands, aerodigestive tract, temporal bone, or skull base. Imaging findings include sinonasal opacification, ocular and other soft-tissue masses, osseous erosion, airway narrowing, lymphadenopathy, and salivary gland infiltration. Vascular involvement may also be evident, with displacement, narrowing, or occlusion of arteries and veins. Some radiologic findings of granulomatous processes have a considerable overlap with findings of malignancy, and a radiologic differential diagnosis inclusive of both is critical to avoid incorrect clinical treatment. Without the benefit of a prior clinical diagnosis, laboratory findings, or suggestive clinical signs and symptoms, granulomatous diseases may be difficult to differentiate radiologically. Although individual granulomatous diseases may have overlapping findings at imaging, certain radiologic findings should prompt the inclusion of granulomatous diseases in the differential diagnosis, thus facilitating appropriate clinical management.

    Epicutaneous patch testing is the gold standard method for the diagnosis of allergic contact dermatitis. Despite this knowledge, many clinical dermatologists do not offer patch testing in their offices or offer testing with only a limited number of allergens. Introduced in 1995, the Thin-Layer Rapid Use Epicutaneous Test originally contained 23 allergens and one control. In 2007, five additional allergens were added. This United States Food and Drug Administration-approved patch testing system made patch testing more convenient, and after its introduction, more dermatologists offered patch testing services. However, the number of allergens in the Thin-Layer Rapid Use Epicutaneous Test remains relatively low. Every two years, the North American Contact Dermatitis Group collects and reports the data from patch testing among its members to a standardized series of allergens. In 2005-2006, the Group used a series of 65 allergens. Of the top 30 allergens reported in 2005-2006, 10 were not included in the Thin-Layer Rapid Use Epicutaneous Test. Knowledge of and testing for additional allergens such as these may increase patch testing yield. PMID:20967194

    There remains lack of agreement on diagnostic criteria and approaches to treatment of patients with Allergic Bronchopulmonary Aspergillosis (ABPA). The results of a survey of AAAAI members regarding these 2 issues are presented and compared for concordance with published recommendations. The literature was reviewed for pertinent reports and an electronic survey was conducted of AAAAI members and fellows regarding diagnostic criteria, numbers of patients evaluated for ABPA, and treatment approaches. From 508 respondents to the survey sent to 5155 U. S. physicians in the AAAAI database of members and fellows, 245 (48%) health professionals had treated at least 1 patient with ABPA in the previous year. For the diagnosis of ABPA, there was a difference in the threshold concentration of total serum IgE as 44.9% used ≥ 417 kU/L whereas 42.0% used ≥ 1000 kU/L. These findings suggest that ABPA might be underdiagnosed. Regarding pharmacotherapy, oral steroids were recommended for 97.1% of patients and oral steroids + inhaled corticosteroids + anti-fungal agent were utilized in 41.2% of patients. The armamentarium for treatment of ABPA includes oral corticosteroids as the initial treatment with inhaled corticosteroids used for management of persistent asthma. Azoles remain adjunctive. Published experience with omalizumab has been limited. PMID:25439360

    Anaphylaxis is characterized by the sudden onset of acute allergic symptoms involving two or more organ systems. An acute allergic emergency is a challenge for physicians due to its life-threatening potential. The incidence of anaphylactic reactions has increased in recent years. Most frequent elicitors of mast cell and primarily histamine dependent anaphylactic reactions are food, insect venom or drugs. Allergic -reactions are graded into four groups according to the classification by Ring and Messmer; grade I is defined by the onset of cutaneous symptoms only whereas grade IV is characterized by cardiovascular shock as well as cardiac and/or respiratory arrest. The treatment of allergic reactions should be guided by the severity of the reaction. Initially an intramuscular epinephrine injection into the lateral thigh should be given if cutaneous, mucosal and cardiovascular/respiratory symptoms occur. Additionally, the patient should receive intravenous antihistamines and corticosteroids. For self-treatment in the case of an allergic emergency, oral antihistamines and corticosteroids should be prescribed to the patient. PMID:24673732

    Pulmonary nocardiosis is a granulomatous disease with high mortality that affects both immunosuppressed and immunocompetent patients. The mechanisms leading to the establishment and progression of the infection are currently unknown. An animal model to study these mechanisms is sorely needed. We report the first in vivo model of granulomatous pulmonary nocardiosis that closely resembles human pathology. BALB/c mice infected intranasally with two different doses of GFP-expressing Nocardia brasiliensis ATCC700358 (NbGFP), develop weight loss and pulmonary granulomas. Mice infected with 109 CFUs progressed towards death within a week while mice infected with 108 CFUs died after five to six months. Histological examination of the lungs revealed that both the higher and lower doses of NbGFP induced granulomas with NbGFP clearly identifiable at the center of the lesions. Mice exposed to 108 CFUs and subsequently to 109 CFUs were not protected against disease severity but had less granulomas suggesting some degree of protection. Attempts to identify a cellular target for the infection were unsuccessful but we found that bacterial microcolonies in the suspension used to infect mice were responsible for the establishment of the disease. Small microcolonies of NbGFP, incompatible with nocardial doubling times starting from unicellular organisms, were identified in the lung as early as six hours after infection. Mice infected with highly purified unicellular preparations of NbGFP did not develop granulomas despite showing weight loss. Finally, intranasal delivery of nocardial microcolonies was enough for mice to develop granulomas with minimal weight loss. Taken together these results show that Nocardia brasiliensis microcolonies are both necessary and sufficient for the development of granulomatous pulmonary nocardiosis in mice. PMID:27303806

    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.

The microscopic changes caused by such deposits and the histologic methods of identifying medicines are presented. The authors point to the role of aspiration in deposit formation and to the pseudomiliary granulomatous nature of subsequent changes. It is proposed to define the alterations as a separate form of aspiratory lesion in children. PMID:3296546

    We report a case of acute kidney injury as the initial manifestation of sarcoidosis. A 55-year-old male was sent from his primary care physician's office with incidental lab findings significant for hypercalcemia and acute kidney injury with past medical history significant for nephrolithiasis. Initial treatment with intravenous hydration did not improve his condition. The renal biopsy subsequently revealed granulomatous interstitial nephritis (GIN). Treatment with the appropriate dose of glucocorticoids improved both the hypercalcemia and renal function. Our case demonstrates that renal limited GIN due to sarcoidosis, although a rare entity, can cause severe acute kidney injury and progressive renal failure unless promptly diagnosed and treated.

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.

    Granulomatous interstitial nephritis (GIN) is a rare histologic disease. Various causes have been reported in the literature, including drugs, sarcoidosis, and infections. Other incidents have no discernible cause and are identified as idiopathic. We report a 68-year-old white man who presented with acute kidney injury and was given a diagnosis of idiopathic GIN. Mycophenolate mofetil treatment was elected because of steroid toxicity. He responded well to mycophenolate mofetil and has been in remission for more than 3 years. To our knowledge, this is the first report of successful treatment with mycophenolate mofetil of an adult patient with idiopathic GIN. PMID:24315767

    Granulomatous interstitial nephritis (GIN) is an uncommon cause of renal failure, which may be caused by drugs. Levetiracetam is an increasingly used anti-epileptic medication that is not known to cause renal toxicity in adults. To our knowledge, levetiracetam has not previously been reported as a cause of GIN. We report the case of a 69-year-old woman who developed haemodialysis-requiring acute renal failure after commencement of treatment with levetiracetam, which was shown to be GIN by renal biopsy. She made a complete recovery with cessation of levetiracetam and treatment with steroids. PMID:26069773

    2010-01-01

    Perforating folliculitis is characterized by asymptomatic skin-coloured or erythematous scattered and aggregated follicular papules with a central keratotic plug. Histologically, a superficial type can be distinguished from the profound type where perforations and rupture of the follicular wall take place at different levels of the hair follicle. This goes along with a granulomatous reaction of the entire pilary complex with destruction of the follicle epithelium and sebaceous gland. Often cases are associated with systemic disorders such as renal diseases or diabetes mellitus. We describe two patients with the profunda type of perforating folliculitis with scarring that manifested in early adulthood without any underlying disorders. PMID:20176545

    We here provide an update on the literature regarding local allergic rhinitis (LAR). In reviewing LAR, we have included an updated definition, classifications, mechanisms, comorbidities, and recommendations for diagnosis and treatment for LAR, as well as the defined research areas for future evidence-based studies. LAR is a localised nasal allergic response in the absence of systemic atopy characterised by local production of specific IgE (sIgE) antibodies, a TH2 pattern of mucosal cell infiltration during natural exposure to aeroallergens, and a positive nasal allergen provocation test response, with the release of inflammatory mediators. The localised allergic response of LAR is an important topic for the study of allergies. This review provides an update on the current knowledge of LAR. PMID:27368453

    Objective. To determine the prevalence of herbal treatment of allergic rhinitis. Methods. In this prospective study, patients who were diagnosed with perennial allergic rhinitis were questioned about their use of natural products/herbal therapies for their symptoms. Results. In total, 230 patients were enrolled. Overall, 37.3% of the patients stated that they had used natural products/herbal therapies at least once. Women were more likely than men to use herbal supplements (38.3% versus 32.4%). Ten different types of herbal supplements were identified, with stinging nettle (Urtica dioicath), black elderberry (Sambucus nigra), and Spirulina being the most common (12.6%, 6.1%, and 5.7%, resp.). Conclusion. This study found a high prevalence of herbal treatment usage for the relief of allergic rhinitis symptoms in Turkey. The herbal products identified in this study and in the literature are discussed. PMID:24324897

    Eosinophils are circulating granulocytes involved in pathogenesis of asthma. A cascade of processes directed by Th2 cytokine producing T-cells influence the recruitment of eosinophils into the lungs. Furthermore, multiple elements including interleukin (IL)-5, IL-13, chemoattractants such as eotaxin, Clara cells, and CC chemokine receptor (CCR)3 are already directly involved in recruiting eosinophils to the lung during allergic inflammation. Once recruited, eosinophils participate in the modulation of immune response, induction of airway hyperresponsiveness and remodeling, characteristic features of asthma. Various types of promising treatments for reducing asthmatic response are related to reduction in eosinophil counts both in human and experimental models of pulmonary allergic inflammation, showing that the recruitment of these cells really plays an important role in the pathophysiology of allergic diseases such asthma.

    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.

  17. Deficient autophagy unravels the ROS paradox in chronic granulomatous disease.

    Autophagy defects resulting in inflammation appear to be a key feature in the pathogenesis of Crohn colitis. An inflammatory colitis indistinguishable from Crohn disease is described in patients with chronic granulomatous disease (CGD). Patients with CGD have a mutated NADPH complex and are therefore deficient in reactive oxygen species (ROS) production; however, the underlying mechanism for the inflammatory colitis in CGD remained unknown. In a recent study, our group reported that NADPH-dependent ROS deficiency results in autophagic dysfunction that subsequently contributes to increased IL1B/interleukin 1β production. Mice deficient in the NADPH-complex component NCF4/p40phox, and CGD patients with a defect in NCF4 display minimal recruitment of LC3 to phagosomes in response to internalized bacteria and fungi. Human monocytes from patients with CGD with defective LC3 recruitment show increased IL1B production after LPS stimulation. Blocking IL1 protects NCF4-deficient mice from experimental colitis; importantly, improved clinical outcome in 2 CGD patients with colitis is also observed with IL1 blockade. Moreover, blocking IL1 restores defective autophagy in CGD mice and cells from patients with CGD. Thus, autophagic dysfunction underlies the pathogenesis of granulomatous colitis in CGD, and blocking IL1 can be used to treat CGD colitis. PMID:24879159

    Non-necrotic epithelioid granulomas have been reported in association with neoplasms including Hodgkin and non-Hodgkin lymphoma. We report a case of diffuse large B cell lymphoma with chronic granulomatous inflammation to highlight awareness of obscure tumour cells within the granuloma, to avoid delay in diagnosis and management of lymphoma. A 39-year-old Malay lady with no past medical history, presented with a 2-month history of progressive worsening of difficulty in breathing, cough, low-grade fever, loss of weight and loss of appetite. Chest X-ray showed an anterior mediastinal mass and computed tomography (CT)-guided biopsy was reported as chronic granulomatous inflammation suggestive of tuberculosis. After 2 months of anti-TB treatment, her symptoms were not relieved. The patient underwent another CT-guided biopsy of the anterior mediastinal mass in another hospital and the histopathology revealed diffuse large B cell lymphoma. The patient was referred for treatment. On histopathological review, the first sample showed noncaseating granulomas engulfing tumour cells and large abnormal lymphoid cells which were CD20 positive and with high Ki-67 proliferative index. The patient was diagnosed with diffuse large B cell lymphoma stage IV B IPSS score 3. She underwent chemotherapy (R-EPOCH) and responded well to treatment. PMID:27126666

    Chronic granulomatous disease (CGD) is a primary immunodeficiency caused by lack of phagocyte nicotinamide adenine dinucleotide phosphate (NADPH) oxidase, which results in inflammatory dysregulation and increased susceptibility to infections. Patients with CGD may develop severe obstructive disorders of the digestive tract as a result of their dysregulated inflammatory response. Despite a growing focus on inflammatory manifestations in CGD, the literature data on obstructive complications are far less extensive than those on infectious complications. Diagnosis and management of patients with concomitant predispositions to infections and hyperinflammation are particularly challenging. Although the inflammatory and granulomatous manifestations of CGD usually respond rapidly to steroid treatment, second-line therapies (immunosuppressants and biologics) may be required in refractory cases. Indeed, immunosuppressants (such as anti-tumor necrosis factor agents, thalidomide, and anakinra) have shown some efficacy, but the value of this approach is controversial, given the questionable risk-to-benefit ratio and the small numbers of patients treated to date. Significant progress in allogeneic hematopoietic stem cell transplantation (the only curative treatment for CGD) has been made through better supportive care and implementation of improved, reduced-intensity conditioning regimens. Gene therapy may eventually be an option for patients lacking a suitable donor; clinical trials with new, safer vectors are ongoing at a few centers. PMID:27299584

    2011-01-01

    Rhinitis is a global problem and is defined as the presence of at least one of the following: congestion, rhinorrhea, sneezing, nasal itching, and nasal obstruction. The two major classifications are allergic and nonallergic rhinitis (NAR). Allergic rhinitis occurs when an allergen is the trigger for the nasal symptoms. NAR is when obstruction and rhinorrhea occurs in relation to nonallergic, noninfectious triggers such as change in the weather, exposure to caustic odors or cigarette smoke, barometric pressure differences, etc. There is a lack of concomitant allergic disease, determined by negative skin prick test for relevant allergens and/or negative allergen-specific antibody tests. Both are highly prevalent diseases that have a significant economic burden on society and negative impact on patient quality of life. Treatment of allergic rhinitis includes allergen avoidance, antihistamines (oral and intranasal), intranasal corticosteroids, intranasal cromones, leukotriene receptor antagonists, and immunotherapy. Occasional systemic corticosteroids and decongestants (oral and topical) are also used. NAR has 8 major subtypes which includes nonallergic rhinopathy (previously known as vasomotor rhinitis), nonallergic rhinitis with eosinophilia, atrophic rhinitis, senile rhinitis, gustatory rhinitis, drug-induced rhinitis, hormonal-induced rhinitis, and cerebral spinal fluid leak. The mainstay of treatment for NAR are intranasal corticosteroids. Topical antihistamines have also been found to be efficacious. Topical anticholinergics such as ipratropium bromide (0.03%) nasal spray are effective in treating rhinorrhea symptoms. Adjunct therapy includes decongestants and nasal saline. Investigational therapies in the treatment of NAR discussed include capsaicin, silver nitrate, and acupuncture. PMID:21738880

    Cetaceans are well known definitive hosts of parasitic nematodes of the genus Anisakis (Nematoda: Anisakidae). Anisakid nematodes are also a health hazard for humans, potentially causing gastrointestinal infections or allergic reactions following the consumption of infected fish. In marine mammals, the nematodes develop from third-stage larvae to adults in the stomachs. In the first (or fore-) stomach, these parasites are typically associated with mucosal ulceration; parasites have not been identified in other organs. Two small cetaceans, a bottlenose dolphin Tursiops truncatus and a harbour porpoise Phocoena phocoena, presented marked gastric A. simplex infection, as well as chronic granulomatous and ulcerative dermatitis with intralesional nematodes, bordered by epithelial hyperplasia. Nematodes in the skin of the bottlenose dolphin were morphologically similar to Anisakis spp. Morphology of the parasitic remnants in the skin lesion of the harbour porpoise was indistinct, but molecular identification confirmed the presence of A. simplex. This is the first report of Anisakis spp. infection in the skin of marine mammals. PMID:25590777

    Granulomatous nephritis can be triggered by diverse factors and results in kidney failure. However, despite accumulating data about granulomatous inflammation, pathogenetic mechanisms in nephritis remain unclear. The DNA-binding high-mobility group box-1 protein (HMGB1) initiates and propagates inflammation when released by activated macrophages, functions as an “alarm cytokine” signaling tissue damage. In this study, we demonstrated elevated HMGB1 expression in renal granulomas in rats with crystal-induced granulomatous nephritis caused by feeding an adenine-rich diet. HMGB1 levels were also raised in urine and serum, as well as monocyte chemoattractant protein-1 (MCP-1), a mediator of granulomatous inflammation. Injection of HMGB1 worsened renal function and upregulated MCP-1 in rats with crystal-induced granulomatous nephritis. HMGB1 also induced MCP-1 secretion through mitogen-activated protein kinase (MAPK) and phosphoinositide-3-kinase (PI3K) pathways in rat renal tubular epithelial cells in vitro. Hmgb1+/− mice with crystal-induced nephritis displayed reduced MCP-1 expression in the kidneys and in urine and the number of macrophages in the kidneys was significantly decreased. We conclude that HMGB1 is a new mediator involved in crystal-induced nephritis that amplifies granulomatous inflammation in a cycle where MCP-1 attracts activated macrophages, resulting in excessive and sustained HMGB1 release. HMGB1 could be a novel target for inhibiting chronic granulomatous diseases. PMID:20231821

    Granulomatous amebic encephalitis is a life-threatening central nervous system (CNS) infection caused by the free-living amoebae Acanthamoeba spp., Balamuthia mandrillaris and Sappinia pedata. The disease has a subacute to chronic onset affecting commonly the immunocompromised population with high mortality rate. The diagnosis of this disease entity requires high suspicion with appropriate sample collection and testing by the laboratory experts. Radiological investigations are nonspecific and commonly confused with CNS tuberculosis, neurocysticercosis, disseminated encephalomyelitis, viral encephalitis etc., delaying the accurate diagnosis of these cases. Early diagnosis plays a crucial role in the survival of these cases since appropriate management can be initiated. No single drug is effective; hence multiple antibiotics targeting various proteins or receptors are required for successful treatment. A combination of surgical and medical interventions involving multiple specialty experts is required to prevent death and morbidity in survivors. PMID:25709949

    Sarcoidosis is a systemic granulomatous disease of unclear etiology with characteristic pulmonary lesions. We describe 2 unique cases of sarcoidosis where after approximately 20 years of clinical quiescence, patients developed interstitial opacities on chest CT scan and an increase in shortness of breath. With lack of therapeutic response to a course of prednisone, both patients underwent a surgical lung biopsy that revealed a pattern consistent with Usual Interstitial Pneumonia (UIP) with honeycombing and fibroblastic foci. Postoperatively, the course of the disease was consistent with what would be expected in Idiopathic Pulmonary Fibrosis. Ultimately the disease progressed with one patient needed lung transplantation and the other requiring high-flow oxygen supplementation. In conclusion, we present two patients in whom a diagnosis of sarcoidosis preceded the diagnosis of UIP by 20 years or more. The subsequent course of disease in both patients was consistent with Idiopathic Pulmonary Fibrosis. PMID:26278696

    Chronic Granulomatous Disease (CGD) is an inherited primary immunodeficiency disease which increases the body's susceptibility to infections caused by certain bacteria and fungi. CGD is a rare disease, caused by four genes, one type is 1X linked and the other three are "autosomal recessive". Although clinical presentation is variable, but characteristic features are recurrent pneumonia, lymphadenitis, hepatic or other abscesses. Gastrointestinal tract symptoms are common in x-linked recessive form of CGD. These include gastric and esophageal obstruction and inflammatory bowel disease. GI involvement including small and large intestines, the findings of luminal narrowing and the presence of granuloma can make it difficult to distinguish from Crohn's disease. On the other hands according to the literature ulcerative colitis is rarely reported in patients with CGD. Our case presented with ulcerative colitis with CGD. PMID:26328046

We report a 41-year-old man with lateral medullary infarction who developed rapidly progressive renal failure. He was diagnosed with GPA based on positive serum c-ANCA and antiproteinase 3 antibodies and demonstration of pauci-immune crescentic glomerulonephritis on kidney biopsy. He was treated with Coumadin, pulse steroids, cyclophosphamide, and plasmapheresis. He had resolution of his neurologic deficits and improvement in renal function. This case report highlights the importance to consider GPA vasculitis in the differential diagnosis of stroke in patients with development of acute kidney injury. PMID:24128976

    Leishmaniasis recidiva cutis (LRC) is an unusual form of acute cutaneous leishmaniasis. Herein, we present a case of LRC of the lips mimicking granulomatous cheilitis. An 8-year-old, Syrian child admitted with a swelling and disfigurement of his lips for 4 years. Abundant intra and extracellular Leishmania amastigotes were determined in the smear prepared from the lesion with Giemsa stain. Histopathology showed foamy histiocytes and leishmania parasites within the cytoplasm of macrophages in the epidermis and a dense dermal mixed type inflammatory cell infiltrate composed of lymphocytes, foamy histiocytes with multinucleated giant cells. On the basis of anamnestic data, the skin smears results, clinical and histopathologic findings, LRC was diagnosed. The patient was treated with meglumine antimoniate intramuscularly and fluconazole orally. Cryotherapy was applied to the residual papular lesions. The lesion improved markedly at the first month of the treatment. PMID:25814756

    Cosmetic tattooing involves implantation of pigments into the dermis in order to create a permanent makeup. Here, we report a case of sarcoidal granulomatous reaction to old cosmetic tattoos after an intense pulsed light (IPL) treatment for facial skin rejuvenation. We consider this case as a peculiar example of photo-induced reaction to tattoo. In addition, we hypothesize that an underlying immune dysfunction was present, and acted as a predisposing factor for this unusual response, as the patient had suffered from an episode of acute pulmonary sarcoidosis 15 years before. Overall, our observation suggests that IPL treatment should be used cautiously in patients with tattoos, especially when a history of autoimmune disease is present. PMID:21175859

    BACKGROUND--Bladder instillations with Bacillus Calmette-Guerin (BCG) are commonly used as immunotherapy for bladder carcinoma. Sometimes patients experience serious systemic side effects, such as sepsis or pneumonitis. Granulomatous hepatitis is a rare serious side effect, which has been considered a hypersensitivity reaction to BCG. PATIENT--The first case of granulomatous hepatitis after BCG bladder instillation in which mycobacteria were identified by staining techniques and mycobacterial DNA was detected in liver tissue using the polymerase chain reaction is reported. CONCLUSION--The granulomatous hepatitis was caused by BCG infection of the liver after haematogenous dissemination of BCG, rather than hypersensitivity. Images p617-a PMID:8707098

    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

    2010-01-01

    Chronic granulomatous disease (CGD) is a rare primary immunodeficiency with x-linked or autosomal recessive inheritance involving defects in genes encoding phox proteins which are the subunits of the phagocyte NADPH oxidase. This results in failure to produce superoxide anion and downstream antimicrobial oxidant metabolites and to activate antimicrobial proteases. Affected patients are susceptible to severe, life-threatening bacterial and fungal infections and excessive inflammation characterized by granulomatous enteritis resembling Crohn's disease and genitourinary obstruction. Early diagnosis of CGD and rapid treatment of infections are critical. Prophylaxis with antibacterial and mould-active antifungal agents and the administration of interferon-γ has significantly improved the natural history of CGD. Currently, the only cure is allogeneic hematopoietic cell transplant (HCT) although there remains controversy as to which patients with CGD should get a transplant. Allele-based HLA typing of alternative donors, improved supportive care measures and use of reduced toxicity conditioning have resulted in EFS of at least 80% even with an unrelated donor and even better when the patient has no active infections/inflammation. Gene correction of CGD would eliminate the risks of GVHD and the immunoablative chemotherapy required for allogeneic HCT. Based on gene therapy trials in patients with SCID-X1, ADA-SCID and the early experience with CGD, it is clear that at least some degree of myeloablation will be necessary for CGD as there is no inherent selective growth advantage for gene-corrected cells. Current efforts for gene therapy focus on use of lentivector constructs which are thought to be safer from the standpoint of insertional mutagenesis and more efficient in transducing hematopoietic stem cells.

    Eosinophils form 50% of cells in the host granulomatous response to Schistosoma mansoni eggs, but their functional role in these granulomas and their relation to egg destruction is unknown. We have studied the course of S. mansoni infection in mice treated with normal rabbit serum (NRS) or depleted of their eosinophils by monospecific anti-eosinophil serum (AES). At 6-wk of infection (after 2 wk of egg deposition) the AES-treated animals were similar to NRS-treated controls with the exception that hepatic granulomas in the AES-treated animals were 50% smaller and devoid of eosinophils. At 8 wk of infection, AES-treated mice had significantly higher mortality, spleen weight, portal pressure, and 80% more eggs retained in their livers. These data suggest that eosinophil depletion delayed egg destruction. We subsequently studied destruction of eggs injected into the pulmonary microvasculature of sensitized mice. 2,000 S. mansoni eggs were intravenously injected into the tail veins of mice treated with NRS, anti-neutrophil serum, AES or ATG (anti-thymocyte globulin); at time intervals the remaining eggs were recovered from the lungs by tissue digestion. Egg recovery from NRS- or anti-neutrophil serum-treated mice began to decrease by day 16 and the percent recovery of eggs at day 24 was 55 and 52%, respectively. In contrast, animals treated with AES had smaller lung granulomas that were devoid of eosinophils and a marked delay of egg destruction was seen. It took until day 44 for 50% of the eggs to be destroyed. In ATG-treated animals smaller granulomas were seen that had diminished lymphocytes and also 75% less eosinophils. ATG treatment apparently slowed egg destruction but was not statistically significant. Our data define the role of the eosinophils in destruction of schistosome eggs in vivo and delineates the protective function of these cells within the host granulomatous response. PMID:7440710

    2011-01-01

    Allergic Aspergillus sinusitis (AAS) is a three decade old clinicopathologic entity in which mucoid impaction akin to that of allergic bronchopulmonary aspergillosis (ABPA) occurs in the paranasal sinuses. Features such as radiographic evidence of pansinusitis, passage of nasal plugs and recurrent nasal polyposis in patients with an atopic background is suggestive of AAS. Histopathlogic confirmation from the inspissated mucus is a sine qua non for the diagnosis. Heterogeneous densities on computed tomography of the paranasal sinuses are caused by the 'allergic mucin' in the sinuses. Many patients give a history of having undergone multiple surgical procedures for symptomatic relief. The current approach to treatment appears to include an initial surgical debridement followed by postoperative oral corticosteroids for long durations. Although both ABPA and AAS are classified as Aspergillus-related hypersensitivity respiratory disorders, their co-occurrence appears to be an infrequently recognised phenomenon. This could perhaps be attributed to the fact that these two diseases are often treated by two different specialties. A high index of suspicion is required to establish the diagnoses of ABPA and AAS. All patients with asthma and/or rhinosinusitis along with sensitisation to Aspergillus antigens are at an increased risk of developing ABPA and/or AAS. ABPA must be excluded in all patients with AAS and vice versa. Early diagnosis and initiation of appropriate therapy could plausibly alter the course of the disease processes and prevent the possible development of long term sequelae. PMID:22053309

    Allergy either results from a pathological excessive immune reaction, or from the defective induction of tolerance to otherwise harmless antigens. Allergic reactions are mounted by mechanisms of innate and adaptive immunity. The development of an allergic response can be divided in sensitization and elicitation phases. Immediate type allergic reactions (e.g. anaphylaxis, urticaria, rhinoconjunctivitis allergica, allergic asthma) are mediated by IgE antibodies which are produced by B cells stimulated by allergen-specific Th2 cells. Crosslinking of allergen-specific IgE on membrane surfaces of mast cells and basophilic granulocytes leads to release of soluble mediators which may cause systemic symptoms within minutes to hours. The following infiltration of eosinophilic granulocytes and Th2 cells directs chronic inflammation. Humoral cytotoxic immune reactions (e.g. drug induced cytopenia) are mediated by IgG and IgM antibodies which are directed against membrane associated antigens. IgG and IgM antibodies directed against soluble antigens elicit immune complex mediated cytotoxicity (e.g.drug induced vasculitis). Delayed type immune reactions (e.g.contact dermatitis) are based on the activation of antigen specific CD4(+) and CD8(+) T cells and need 24 h to 48 h to develop. Upon recurrent contact with identical antigens, recruitment of CD4(+) and CD8(+) T cells cause inflammation and cytotoxic induced apoptosis in target cells as well as cytokine mediated leukocyte infiltration. Subsequent immigration of CD4(+) Th2 cells provides anti-inflammatory mechanisms leading to resolution of the inflammatory response and tissue repair. PMID:17976144

    Allergic rhinitis (AR) clinically expressed by sneezing, rhinorrhea, nasal itching and congestion is an allergen-driven mucosal inflammatory disease which is modulated by immunoglobulin E. Epidemiological studies have indicated that prevalence of AR continues to increase, and it has been a worldwide health problem that places a significant healthcare burden on individuals and society. Given the evolving understanding of the process by which an allergen is recognized and the roles of mediators which account for AR progress, the pathogenesis of AR has become clearer. Current studies have demonstrated local allergic rhinitis (LAR) that patients with both sug- gestive symptoms of AR and a negative diagnostic test for atopy may have local allergic inflammation is a prevalent entity in patients evaluated with rhinitis, but further research remains needed. Management of AR includes aller- gen avoidance, pharmacological treatment and allergen-specific immunotherapy. Recently montelukast has exhibited previously undocumented anti-inflammatory properties, leukotriene receptor antagonists therefore may serve a more important role in the treatment of AR. Not only has immunotherapy proved its efficacy, but also been able to alter disease course and thereby mitigate progression to asthma. Thus immunotherapy can be initiated while receiving pharmacotherapy, especially in children with AR. As clinical guidelines, the ARIA (Allergic Rhinitis and its Impact on Asthma) provides basic principles of effective treatment of AR. Besides, choosing an appropriate treatment strategy should be based on the severity and chronicity of patient's symptom. The aim of this review was to provide an update mainly on the pathophysiology, epidemiology, and management of AR. PMID:26012287

    2016-01-01

    Allergic diseases such as asthma and rhinitis, as well the early phase of atopic dermatitis, are characterized by a Th2-skewed immune environment. Th2-type cytokines are upregulated in allergic inflammation, whereas there is downregulation of the Th1-type immune response and related cytokines, such as interferon-x03B3; (IFN-x03B3;). The latter is a strong inducer of indoleamine 2,3-dioxygenase-1 (IDO-1), which degrades the essential amino acid tryptophan, as part of an antiproliferative strategy of immunocompetent cells to halt the growth of infected and malignant cells, and also of T cells - an immunoregulatory intervention to avoid overactivation of the immune system. Raised serum tryptophan concentrations have been reported in patients with pollen allergy compared to healthy blood donors. Moreover, higher baseline tryptophan concentrations have been associated with a poor response to specific immunotherapy. It has been shown that the increase in tryptophan concentrations in patients with pollen allergy only exists outside the pollen season, and not during the season. Interestingly, there is only a minor alteration of the kynurenine to tryptophan ratio (Kyn/Trp, an index of tryptophan breakdown). The reason for the higher tryptophan concentrations in patients with pollen allergy outside the season remains a matter of discussion. To this regard, the specific interaction of nitric oxide (NO∙) with the tryptophan-degrading enzyme IDO-1 could be important, because an enhanced formation of NO∙ has been reported in patients with asthma and allergic rhinitis. Importantly, NO∙ suppresses the activity of the heme enzyme IDO-1, which could explain the higher tryptophan levels. Thus, inhibitors of inducible NO∙ synthase should be reconsidered as candidates for antiallergic therapy out of season that may abrogate the arrest of IDO-1 by decreasing the production of NO∙. Considering its association with the pathophysiology of atopic disease, tryptophan metabolism may

    Twenty percent of the recent Australian Olympic athletes have had an allergic disorder. Because of the ban on all sympathomimetic drugs except some beta 2-agonists. Olympic team physicians have a major responsibility to ensure that no competitor is disqualified for infringing on the antidoping rules of the Medical Commission of the International Olympic Committee. Inadvertent contravention of these regulations may occur because numerous banned sympathomimetics are available to athletes and their coaches without medical prescription and are frequently contained in combination preparations. The unbroken 24 yr in which asthmatics have won Olympic medals have been both before and after the introduction of drug tests. Currently a comprehensive range of preventive and therapeutic medications are available for asthmatics to compete with minimal respiratory disadvantage. It was, however, during a period of unnecessary restriction that an American swimmer forfeited his gold medal because of prerace ingestion of a banned sympathomimetic agent. Should adverse air quality be encountered during the Los Angeles Olympics, allergic competitors will be among the most inconvenienced . Athletes with allergic rhinitis and sinusitis will be the most disadvantaged because sympathomimetic vasoconstrictors remain banned. It is strongly recommended that the Medical Commission of the International Olympic Committee meet with an appropriate body of experts (i.e., the American Academy of Allergy and Immunology) to review this ban on vasoconstrictor agents.

    Allergic rhinitis (AR) is a high-prevalence disease, triggered by an IgE-mediated reaction, and sustained by a complex inflammatory network of cells, mediators, and cytokines. When the exposure to allergens persists, the inflammatory process becomes chronic. The current therapeutic strategy is based on allergen avoidance when possible, drugs and allergen immunotherapy. The main drugs are oral and topical antihistamines and nasal steroids. They are overall effective in controlling symptoms, but do not modify the immune background that leads to allergic inflammation. In addition, safety concerns may be present, especially for prolonged treatments. Thus, efforts are currently made to improve the existing molecules and to develop new drugs, in order to achieve greater clinical efficacy with a better tolerability. Also, attempts are made to selectively block relevant signal pathways of the allergic reaction by means of specific anti-mediators. Specific immunotherapy, in addition to the clinical effect, is capable of modifying the Th2-biased immune response. Thus, an intense research activity is presently ongoing with the aim of improving the characteristics and modes of action of this treatment. PMID:20001557

    Granulomatous mastitis is a rare benign inflammatory condition of the breast and is known to be associated with pregnancy. A 25-year-old Hispanic G2P1 at 17 weeks gestation presented to the emergency department with findings consistent of a breast abscess. The abscess failed to resolve with incision and drainage followed by multiple courses of antibiotic therapy. A biopsy was then obtained and yielded a diagnosis of granulomatous lobulitis. The patient was treated with steroids and her symptoms resolved. Granulomatous lobulitis may present with characteristics of various clinical entities including neoplasm or, as in this case, abscess. Clinicians should consider a diagnosis of granulomatous mastitis in cases of recalcitrant breast abscess.

    The increase in allergic airways disease has been linked to modern urbanization and lifestyle. Recent evidence suggests that the associated reduction in microbial exposure, reduction in dietary fibre intake and increased antibiotic use may cause early dysbiosis in infancy, which predisposes to immune dysregulation and allergic airways disease later in life. This implies that there may be a window of opportunity for primary prevention strategies aimed to protect or restore the microbiome early in life and thereby decrease the risk of developing allergic airways disease. Alternatively, strategies that correct dysbiosis may aid in the treatment of established allergic airways disease. PMID:27012478

    To our knowledge, we report the first case of sarcoid-like granulomatous reaction induced by nivolumab, a fully human IgG4 anti-programmed death 1 (PD-1) immune checkpoint inhibitor antibody. A 57-year-old man was treated with nivolumab 3 mg/kg for 2 weeks for a desmoplastic melanoma stage III American Joint Commission on Cancer, with no BRAF, NRAS, and cKit mutations. At 10 months, although melanoma complete response was achieved, he developed sarcoid-like granulomatous reaction in the mediastinal lymph node and skin, which resumed after nivolumab arrest. Melanoma did not relapse after 12 months of follow-up. Considering the recently demonstrated role of activated PD-1/PDL-1 axis in sarcoidosis, granulomatous reaction in the patient seems to be a paradoxical reaction, but similar observations have been reported with ipilimumab, another immune checkpoint inhibitor. Sarcoid-like granulomatous reaction during immunotherapy treatment could be a manifestation of cell-mediated immunity induced by these drugs. Impact of granulomatous reaction induced by immune checkpoint inhibitor on melanoma progression is not known and requires further study. Melanoma patients treated by immunotherapy (anti-cytotoxic T-lymphocyte-associated protein-4/anti-PD-1) should be considered for developing sarcoid-like granulomatous reaction that must not be confused with tumor progression.

    Chronic granulomatous disease (CGD) is a primary immunodeficiency caused by failure of superoxide production in phagocytic cells. The disease is characterised by recurrent infections and inflammatory events, frequently affecting the lungs. Improvement of life expectancy now allows most patients to reach adulthood. We aimed to describe the pattern of pulmonary manifestations occurring during adulthood in CGD patients. This was a retrospective study of the French national cohort of adult patients (≥16 years old) with CGD. Medical data were obtained for 67 adult patients. Pulmonary manifestations affected two-thirds of adult patients. Their incidence was significantly higher than in childhood (mean annual rate 0.22 versus 0.07, p=0.01). Infectious risk persisted despite anti-infectious prophylaxis. Invasive fungal infections were frequent (0.11 per year per patient) and asymptomatic in 37% of the cases. They often required lung biopsy for diagnosis (10 out of 30). Noninfectious respiratory events concerned 28% of adult patients, frequently associated with a concomitant fungal infection (40%). They were more frequent in patients with the X-linked form of CGD. Immune-modulator therapies were required in most cases (70%). Respiratory manifestations are major complications of CGD in adulthood. Noninfectious pulmonary manifestations are as deleterious as infectious pneumonia. A specific respiratory monitoring is necessary. PMID:25614174

    Infection of humans with Mycobacterium tuberculosis remains frequent and may still lead to death. After primary infection, the immune system is often able to control M. tuberculosis infection over a prolonged latency period, but a decrease in immune function (from HIV to immunosenescence) leads to active disease. Available vaccines against tuberculosis are restricted to BCG, a live vaccine with an attenuated strain of M. bovis. Immunodeficiency may not only be associated with an increased risk of tuberculosis, but also with local or disseminated BCG infection. Genetic deficiency in the reactive oxygen species (ROS)-producing phagocyte NADPH oxidase NOX2 is called chronic granulomatous disease (CGD). CGD is among the most common primary immune deficiencies. Here we review our knowledge on the importance of NOX2-derived ROS in mycobacterial infection. A literature review suggests that human CGD patient frequently have an increased susceptibility to BCG and to M. tuberculosis. In vitro studies and experiments with CGD mice are incomplete and yielded - at least in part - contradictory results. Thus, although observations in human CGD patients leave little doubt about the role of NOX2 in the control of mycobacteria, further studies will be necessary to unequivocally define and understand the role of ROS.

    Chronic Granulomatous Disease (CGD), caused by genetic defects in components of the phagocyte NADPH oxidase pathway, leads to recurrent life-threatening bacterial and invasive fungal infections. While a number of unique pathogens have been associated with this disease, the causative organisms may be difficult to identify. Here, we present a 24 year old male with known X-linked CGD who concurrently developed a cervical abscess and an abscess in the subcutaneous tissues of the right hip, both of which were surgically drained. Cultures failed to identify any organisms. He was treated empirically with ertapenem but the hip abscess recurred at the original site and in contiguous dependent areas in the posterior thigh and knee. A filamentous organism was observed microscopically, initially considered a contaminant, but on culture yielded a mold growth, identified as Phellinus tropicalis (synonym: Inonotus tropicalis) based on phenotypic and molecular methods. This is the third case report of human infection with P. tropicalis, all in subjects with CGD. The patient was treated with voriconazole with resolution of his symptoms. PMID:24310980

    2014-01-01

    Based on their studies and literature analysis, the authors offer a hypothesis for the adaptive pattern of chronic immune granulomatous inflammation occurring in infectious diseases that are characterized by the development of non-sterile immunity. The authors' proposed hypothesis holds that not every chronic inflammation is a manifestation of failing defenses of the body exposed to a damaging factor. By using tuberculosis and leprosy as an example, the authors show the insolvency of a number of existing notions of the pathogenesis and morphogenesis of epithelioid-cell and leprous granulomas. Thus, the authors consider that resident macrophages in tuberculosis maintain their function to kill mycobacteria; thereby the immune system obtains information on the antigenic determinants of the causative agents. At the same time, by consuming all hydrolases to kill mycobacteria, the macrophage fails to elaborate new lysosomes for the capacity of the pathogens to prevent them from forming. As a result, the lysosome-depleted macrophage transforms into an epithelioid cell that, maintaining phagocytic functions, loses its ability to kill the causative agents. It is this epithelioid cell where endocytobiosis takes place. These microorganisms destroy the epithelioid cell and fall out in the area of caseating granuloma necrosis at regular intervals. Some of them phagocytize epithelioid cells to maintain non-sterile immunity; the others are killed by inflammatory macrophages. The pathogenesis and morphogenesis of leprous granuloma, its tuberculous type in particular, proceed in a fundamentally similar way. Thus, non-sterile immunity required for tuberculosis, leprosy, and, possibly, other mycobacterioses is maintained. PMID:25306624

    We present a case of refractory pneumonia in an adult patient with underlying chronic granulomatous disease (CGD). Her lobectomy tissue grew B urkholderia cepacia and histopathology revealed diffuse severe pneumonic consolidation with suppurative/necrotizing granulomata. An initial attempt to find an underlying immune deficiency was unsuccessful. Following recurrent invasive infections, repeat immunological assessment revealed reduced neutrophil function, demonstrating skewed carrier status (lyonization) for X-linked CGD (only 3% normal cells). A pathogenic mutation in the CYBB gene was found on sequencing. CYBB gene encodes the gp91phox, a catalytic subunit of nicotinamide adenine dinucleotide phosphate-oxidase that produces reactive oxygen species in phagocytes. Lyonization increases with age, explaining the delayed clinical CGD. CGD is a rare neutrophil disorder that usually presents in early life with recurrent infections due to bacteria and fungi primarily involving lungs and skin. It is secondary to a defective NADPH oxidase system needed to kill intracellular organisms and activate the formation of neutrophil extracellular traps. PMID:26090111

    The prevalence of allergic rhinitis (AR) has been estimated at 10% to 40%, and its economic burden is substantial. AR patients develop specific immunoglobulin E (IgE) antibody responses to indoor and outdoor environmental allergens with exposure over time. These specific IgE antibodies bind to high-affinity IgE receptors on mast cells and basophils. Key outcome measures of therapeutic interventions include rhinitis symptom control, rescue medication requirements, and quality-of-life measures. A comprehensive multiple modality treatment plan customized to the individual patient can optimize outcomes. PMID:27083101

    Pneumocystis jirovecii pneumonia (PJP) in patients with HIV infection can, in rare cases, present with pulmonary nodules that histologically involve granulomatous inflammation. This report describes an intriguing case of granulomatous PJP with pulmonary nodules after commencing antiretroviral therapy (ART) in an HIV-infected patient without respiratory signs or symptoms. Diagnosis of granulomatous PJP was only achieved through thoracoscopic lung biopsy. This case suggests that granulomatous PJP should be considered in the differential diagnosis of pulmonary nodules in HIV-infected patients for unmasking immune reconstitution inflammatory syndrome manifestation after initiation of ART.

    During the last few decades, the prevalence of allergic disease has increased dramatically. The development of allergic diseases has been attributed to complex interactions between environmental factors and genetic factors. Of the many possible environmental factors, most research has focused on the most commonly encountered environmental factors, such as air pollution and environmental microbiota in combination with climate change. There is increasing evidence that such environmental factors play a critical role in the regulation of the immune response that is associated with allergic diseases, especially in genetically susceptible individuals. This review deals with not only these environmental factors and genetic factors but also their interactions in the development of allergic diseases. It will also emphasize the need for early interventions that can prevent the development of allergic diseases in susceptible populations and how these interventions can be identified. PMID:25228995

    Allergic diseases, which have escalated in prevalence in recent years, arise as a result of maladaptive immune responses to ubiquitous environmental stimuli. Why only certain individuals mount inappropriate type 2 immune responses to these otherwise harmless allergens has remained an unanswered question. Mounting evidence suggests that the epithelium, by sensing its environment, is the central regulator of allergic diseases. Once considered to be a passive barrier to allergens, epithelial cells at mucosal surfaces are now considered to be the cornerstone of the allergic diathesis. Beyond their function as maintaining barrier at mucosal surfaces, mucosal epithelial cells through the secretion of mediators like IL-25, IL-33, and TSLP control the fate of downstream allergic immune responses. In this review, we will discuss the advances in recent years regarding the process of allergen recognition and secretion of soluble mediators by epithelial cells that shape the development of the allergic response.

    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.

Various diseases have also been suggested, including tuberculosis, sarcoidosis, Crohn's disease, and Yersinia pseudotuberculosis. A case of primary granulomatous inflammation of the appendix is presented, and 61 cases reported in the literature since 1953 are reviewed. Patients presented with pain in the right lower quadrant of the abdomen frequently associated with a mass and a protracted preoperative course. Of the 61 patients, 31 were men, 24 were women, and the sex of six of the patients was not reported. The median age of patients was 21 yr. The majority (77%) underwent simple appendectomy. Of patients undergoing ileocolectomy, five of 14 (36%) had concurrent granulomatous ileal involvement. The majority of specimens exhibited appreciable transmural thickening with fibrosis, noncaseating granulomas, formation of Langhans giant cells, and mucosal ulceration. No operative deaths and no postoperative fecal fistulas occurred. In patients without concurrent or synchronous granulomatous disease elsewhere who were followed from 1 to 16.8 yr (mean 5.2 yr), the incidence of recurrence approximated 14%. Therefore, patients with granulomatous appendicitis appear to have a favorable prognosis but require careful long-term observation. PMID:3962954

    Granulomatous inflammations are a particular type of chronic septic or aseptic inflammation, in which infectious or non-infectious agents are difficult to eliminate by the immune system. These are type IV hypersensitivity reactions mediated by pre-sensitized T-lymphocytes cells CD4+ and CD8+ lymphocytes. Disorders included in this category are: tuberculosis, leprosy, syphilis, sarcoidosis, type I diabetes, multiple sclerosis, Crohn's disease and rheumatoid arthritis. At cutaneous level, this pattern of granulomatous reaction is characterized by a chronic inflammation with formation of granulomas consisting of a variable number of histiocytes, multinucleated giant cells and lymphocytes. Granulomatous dermatoses should be differentiated from other primary or secondary lesions affecting the skin such as inflammation or tumors. Often granulomatous dermatoses can be confused with other skin disorders, both clinically and histological. Histopathology examination can add important information and clarify the diagnosis. This paper presents a series of three clinical cases of granulomatous skin occurring in the elderly patients confirmed at histology examination. Clinical and histology criteria were analyzed, along with specific differential diagnosis, based on data from the literature. PMID:27516029

    Background: Granulomatous amebic encephalitis (GAE) is rare, but often fatal. The infection has been documented predominantly among the immunocompromised population or among those with chronic disease. To date, however, there have only been eight cases regarding the infection following hematopoietic stem cell transplantation (HSCT). Case Description: A 62-year-old female with a history of relapsed diffuse large B-cell lymphoma, recently underwent peripheral blood autologous stem cell transplant after BEAM conditioning (day 0). On day +15, she began to exhibit worsening fatigue, generalized weakness, and fever. Symptoms progressed to nausea, emesis, somnolence, confusion, and frontal headaches over the next few days. Imaging demonstrated multifocal ill-defined vasogenic edema with patchy enhancement. The patient was started on broad antibiotics, antifungals, and seizure prophylaxis. Evaluation for bacterial, fungal, mycobacterial, and viral etiologies was fruitless. Her mental status progressively deteriorated. On day +22, she exhibited severe lethargy and went into pulseless electrical activity arrest, requiring chest compressions. The episode lasted <2 min and her pulse was restored. She was taken to the operating room for a brain biopsy. Postoperatively, her right pupil began to dilate compared to the left; she demonstrated extensor posturing in her upper extremities and withdrawal in her lower extremities. Repeat computed tomography demonstrated progressive edema. Given poor prognosis and poor neurological examination, the family opted for withdrawal of care. Final pathology was consistent with Acanthamoeba GAE. Conclusion: The authors report the third case of GAE after autologous stem cell transplant, and the ninth case overall after HSCT. This case is unusual due to its rapid clinical presentation after HSCT compared to prior literature. The case highlights the need for high suspicion of Acanthamoeba infection in this patient population. PMID:26539322

    Chronic granulomatous disease (CGD) is a primary immunodeficiency that leads to severe recurrent infection and inflammatory complications that are usually difficult to diagnose and treat. Several hyperinflammation mechanisms, such as decreased neutrophil apoptosis, toll-like receptor activation imbalance, Th17 cell induction, Nrf2 activity deficiency, and inflammasome activation, have been described in CGD patients However, there have been no reports of chronic recurrent multifocal osteomyelitis as an inflammatory complication in CGD, and the differential diagnosis of this condition with infectious osteomyelitis is challenging. Thalidomide has been used to treat several inflammatory manifestations in CGD patients with good clinical results. Here, we report the case of a previously asymptomatic 11-year-old boy who consulted for difficulty walking and pain at the back of the right thigh, with increased inflammatory markers. Multifocal bone involvement was seen on bone scintigraphy, and acute-phase reactants were elevated. On the basis of a suspected diagnosis of infectious osteomyelitis, broad-spectrum antibiotic therapy was started, with no clinical response. Bone biopsy and microbiological tests yielded negative results; at that point, chronic recurrent multifocal osteomyelitis was suspected. The patient was unresponsive to nonsteroidal antiinflammatory drugs and corticosteroids. Thalidomide was started, and within 6 months, clinical and radiologic resolution of the condition was achieved with no adverse effects. More than 1 year after stopping thalidomide, the patient remained free of symptoms and inflammatory parameters are within normal levels. Thalidomide has a favorable safety profile compared with other alternatives and could be considered a feasible therapeutic option for this type of condition in selected patients. PMID:27436506

    Chronic granulomatous disease (CGD) is a primary immunodeficiency characterized by recurrent infections and a dysregulated inflammatory response. Infection-triggered hemophagocytic lymphohistiocytosis (HLH), which manifests itself as pathologic hyperactive inflammation, has been observed in subjects with CGD. However, there have been no reports of HLH as the initial presentation with subsequent diagnosis of CGD. Furthermore, the primary therapeutic strategy for HLH focuses on immunosuppressive therapies, which limits immune-mediated tissue damage. With immunodeficiency, this therapeutic strategy may worsen the outcome. This article discusses an 8-week-old Hispanic male who presented with fever of unknown origin. The initial diagnostic evaluation demonstrated pathologic hyperactive inflammation, meeting the HLH-2004 diagnostic criteria without an identified infectious etiology. Immunosuppressive therapy was initiated, with subsequent disseminated candida septic shock and sepsis-induced multisystem organ failure. Additional evaluations ultimately established the diagnosis of CGD. We transitioned to an immune-enhancing strategy with granulocyte and immunoglobulin infusions, and intensified antifungal therapies. These interventions ultimately led to the clearance of the fungal infection and the resolution of the hyperactive inflammatory state. This case represents the first reported case of HLH as the presenting finding leading to the subsequent diagnosis of CGD. It serves as a reminder that both immunodeficiency and inflammatory disorders may share features of pathologic hyperactive inflammation and highlights the conundrum that clinicians face when treating HLH in the setting of an unresolved infection. In this case report, we demonstrate that immune-enhancing therapies may aid in the control and the clearance of the infection, thus paradoxically decreasing the pathologic hyperactive inflammatory response.

    Groups of beagle dogs were exposed by inhalation to attain either low or high initial lung burdens (ILB) of BeO calcined at 500 degrees or 1000 degrees C. Dogs were killed at 8, 32, 64, 180, and 365 days after exposure for evaluation of beryllium tissue burdens and histopathologic examination. Histologic lesions were characterized by perivascular and peribronchiolar infiltrates of lymphocytes and macrophages 8 days after exposure. These lesions progressed to distinct microgranulomas accompanied by patchy granulomatous pneumonia. Lesions were more severe in dogs exposed to 500 degrees C BeO. Additional dogs were sampled by bronchoalveolar lavage at 3, 6, 7, 11, 15, 18, and 22 months after exposure for characterization of lung cytology and lung immune responses. Lymphocyte percentages and numbers were increased in lavage samples 3 months after exposure in dogs with both the high and low ILB of 500 degrees C. Values for both parameters decreased rapidly thereafter. Dogs with either low or high ILB of 1000 degrees C-treated BeO displayed negligible to low and variable changes in both lymphocyte percentages and numbers. In vitro lymphocyte stimulation by beryllium was increased 180 and 210 days after exposure in dogs with the high ILB 500 degrees C BeO only. A marked degree of individual variation in both histologic lesions and lymphocyte responses among dogs was noted. Less soluble 1000 degrees C-treated BeO was retained in the lung longer than the more soluble 500 degrees C-treated material that was cleared almost entirely by 1 year after exposure. Because these changes are similar to those reported in humans with chronic beryllium disease, these data suggest that the beagle represents a good model to study histologic and immunologic aspects of this disease syndrome.

    Chronic granulomatous disease (CGD) is a rare primary immunodeficiency caused by defects in the genes encoding any of the NADPH oxidase components responsible for the respiratory burst of phagocytic leukocytes. CGD is a genetically heterogeneous disease with an X-linked recessive (XR-CGD) form caused by mutations in the CYBB gene encoding the gp91(phox) protein, and an autosomal recessive (AR-CGD) form caused by mutations in the CYBA, NCF1, NCF2, or NCF4 genes encoding p22(phox) , p47(phox) , p67(phox) , and p40(phox) , respectively. Patients suffering from this disease are susceptible to severe life-threatening bacterial and fungal infections and excessive inflammation characterized by granuloma formation in any organ, for instance, the gastrointestinal and genitourinary tract. An early diagnosis of and the prompt treatment for these conditions are crucial for an optimal outcome of affected patients. To prevent infections, CGD patients should receive lifelong antibiotics and antifungal prophylaxis. These two measures, as well as newer more effective antimicrobials, have significantly modified the natural history of CGD, resulting in a remarkable change in overall survival, which is now around 90%, reaching well into adulthood. At present, hematopoietic stem cell transplantation (HSCT) is the only definitive treatment that can cure CGD and reverse organ dysfunction. Timing, donor selection, and conditioning regimens remain the key points of this therapy. In recent years, gene therapy (GT) for XR-CGD has been proposed as an alternative to HSCT for CGD patients without a matched donor. After the failure of the first trials performed with retroviral vectors, some groups have proposed the use of regulated SIN-lentiviral vectors targeting gp91(phox) expression in myeloid cells to increase the safety and efficacy of the GT protocols.

    Textile dermatitis is only one example of adverse health effects due to clothing. It may present with a wide spectrum of clinical features, but the main mechanisms are irritant dermatitis, often observed in atopics intolerant to wool and synthetic fibers, and allergic contact dermatitis, usually caused by textile finishes and dyes. The newer azo dyes Disperse Blue 106 and 124 in particular are potent sensitizers that have caused significant problems, most recently in the form of "leggins dermatitis". Although severe textile dermatitis appears to be a rare event, more systematic population-based research is needed since many oligosymptomatic cases are probably overlooked. Criteria for healthy textiles are an optimum combination of efficacy (regulation of skin temperature and humidity and protection from environmental damage) and safety (lack of carcinogenicity, toxicity and allergenicity). If potentially allergenic substances are used in textiles, they should be declared as in the case of cosmetics. PMID:8115841

    The present report describes a case of granulomatous pneumonia and hepatitis in a male crocodile monitor lizard (Varanus salvadorii). During the necropsy of the monitor lizard, multifocal to coalescing pale yellow lesions were observed in both lung lobes, as well as similar, though milder, changes in the liver, and an ulcerative lesion on the food pad of the right hindlimb. Histopathologically, the presence of multiple necrotising, chronic granulomas containing bacterial clumps were observed in the parenchyma of the lung and the liver. By microbiological examination of the pathologically altered lung tissues, Providencia rettgeri was identified. Altogether, our findings indicate that the bacterial infection resulting in extensive chronic necrotising granulomatous inflammation was the primary cause of the reptile's death. To our knowledge, this is the first report of Providencia rettgeri-associated granulomatous pneumonia and hepatitis in the monitor lizard. PMID:23439291

    We report herein on a case of osteomyelitis with a granulomatous lesion caused by Salmonella enterica subsp. enterica serovar Infantis (Salmonella Infantis). A 30-year-old Japanese man presenting with a 3-week history of left ankle pain was suspected to have either a tumor or osteomyelitis, on the basis of imaging study findings. He underwent a surgical resection of the lesion. Histopathological examination revealed a granuloma. However, S. Infantis was cultured from the biopsy sample. Cefazolin was initially administered as empirical therapy. We switched the antibiotic to ampicillin on the basis of the anitibiotic-susceptibility test results. Six weeks after intravenous ampicillin therapy, we switched to oral ciprofloxacin. He has had no recurrence in the 3 years after treatment completion. Salmonella osteomyelitis is rare and this pathogen seldom causes a granulomatous lesion. According to the findings in our case, Salmonella spp. should be considered as one of the differential diagnoses for granulomatous lesions in the bone. PMID:26554224

    Herein we report a 52-year-old man with subacute right-sided proptosis and diffuse intraconal enhancing abnormality on MRI. Orbital biopsy revealed granulomatous inflammation consistent with idiopathic orbital inflammatory syndrome (IOIS), or orbital pseudotumor. However, further examination under polarizing light microscopy also revealed acetate fiber fragments within the orbit. Prominent speckles within the acetate fibers were identified as titanium by Energy Dispersive X-ray Analysis (EDXA). Acetate impregnated with titanium (as a delustrant) is a common synthetic fiber used in textile and clothing manufacture. The mechanism for entrance into the orbit in this case is not known. Granulomatous idiopathic orbital inflammatory syndrome without local or systemic cause is an uncommon clinical entity, with less than 50 cases reported in the literature. Predominance of lacrimal gland (and thus superficial) involvement in granulomatous IOIS suggests the possibility of occult foreign body in such cases. PMID:20497088

    There are multiple clinical and histopathologic presentations of cutaneous metastases. We report 3 cases of visceral malignancies metastasizing to the skin and histopathologically mimicking interstitial granulomatous processes, including granuloma annulare and interstitial granulomatous dermatitis. Histopathologic examination of skin biopsy specimens, from our patients with established histories of cancer, revealed malignant carcinoma-derived cells organized in an interstitial pattern. Of note, some of the lesional cells appeared relatively bland without significant cellular atypia. When examining a skin biopsy of a new lesion from a patient with a history of internal malignancy, it is important to perform immunohistochemical staining to evaluate for metastatic disease, even if the histological pattern is suggestive of a benign interstitial granulomatous process.

Environmental factors including stress-induced corticosterone and vitamin E isoforms during pregnancy regulate the risk for offspring development of allergy. In this review, we discuss mechanisms for the development of allergic disease early in life, environmental factors that may impact the development of risk for allergic disease early in life, and how the variation in global prevalence of asthma may be explained, at least in part, by some environmental components.

    Objective: In this study we aimed to define clinical, radiologic and pathological specialties of patients who applied to General Surgery Department of Atatürk University Medical Faculty with granulomatous mastitis and show medical and surgical treatment results. With the help of this study we will be able to make our own clinical algorithm for diagnosis and treatment. Materials and Methods: 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. Results: 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. Conclusion: 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

    Background Chronic granulomatous disease is a rare immunodeficiency complicated by dysregulated inflammation and granulomatous complications of the gastrointestinal tract. The management of chronic granulomatous disease colitis presents the dilemma of an immunocompromised host requiring immunosuppressive therapy which can potentiate fatal infections. Objective To identify the types of gastrointestinal surgery performed in patients and determine the role of surgery in the management of refractory colitis. Design and Settings A retrospective single institution chart review was performed. Patients Of 268 patients with chronic granulomatous disease treated at the National Institutes of Health between 1985 and 2011, 98 (37%) were identified as having colitis; 27 (10%) had a history of gastrointestinal luminal surgery. Main outcome measures Patient characteristics, type of gastrointestinal surgery and clinical outcomes were documented. Results A total of 62 gastrointestinal luminal surgeries were performed in 27 patients with chronic granulomatous disease and colitis. All 27 had a history of perineal disease requiring intervention. Four (15%) had additional surgery performed for reasons other than colitis. Otherwise, 12 (44%) had surgery limited to the perineum, 2 (7%) had a segmental resection and 13 (48%) underwent fecal diversion with ileostomy or colostomy. Despite local procedures, 7 (58%) patients in the perineal only group remained symptomatic. Both patients with a segmental resection had persistent perineal disease and 1 had a recurrent colovesicular fistula. Of the 13 ostomy patients, 11 initially received a diverting ostomy. Eight (73%) of these ultimately required additional procedures for refractory disease and 4 (36%) developed peristomal pyoderma gangrenosum. Four patients who underwent proctocolectomy with end ileostomy, either initially (2) or as a definitive procedure (2), experienced resolution of colitis and perineal disease.

    Reporting two of our cases we wanted to point to a great dilemma related to the final diagnosis. Recently, such cases have been more frewuently seen, since in all patients with allergic rhinitis conditions of the lower airways is examined before the administration of the specific immunotherapy. Therefore, we may see patients who are still free of pulmonary sings, despite of positive specific and/or non specific bronchoprovocative tests. The presented cases with evidenced allergic rhinitis are probably in the phase of development of allergic bronchial asthma, the phase of "allergic inflammation" of the lower airways, not clinically manifested yet.

    Two patients with histologically diagnosed starch induced granulomatous peritonitis (SGP) have been shown to have cell mediated immunity to corn starch using the techniques of macrophage migration inhibition and lymphocyte DNA synthesis. Control groups of normal subjects, patients with uncomplicated laparotomy, and patients with Crohn's disease were negative in both tests. Lymphocytes from two patients with band adhesions, one of whom had biopsy evidence of a granulomatous reaction to starch, were sensitized to starch. Cell mediated immunity to starch may contribute to the pathogenesis of SGP, and some band adhesions may be a chronic low grade manifestation of this disorder. PMID:1269987

    Leprosy and tuberculosis are chronic mycobacterial infections that elicit granulomatous inflammation. Both infections are curable, but granulomatous injury to cutaneous structures, including cutaneous nerves in leprosy, may cause permanent damage. Both diseases are major global concerns: tuberculosis for its high prevalence and mortality, and leprosy for its persistent global presence and high rate of neuropathic disability. Cutaneous manifestations of both leprosy and tuberculosis are frequently subtle and challenging in dermatologic practice and often require a careful travel and social history and a high index of suspicion.

    Granulomatous diseases are caused by multiple infectious and noninfectious causes. Deep fungal infections can present in the skin or extracutaneously, most commonly with lung manifestations. An Azole or amphotericin B is the universal treatment. Blastomycosis-like pyoderma is a clinically similar condition, which is caused by a combination of hypersensitivity and immunosuppression. Successful treatment has been reported with antibiotics and, more recently, the vitamin A analog, acitretin. Granuloma inguinale and lymphogranuloma venereum cause ulcerative genital lesions with a granulomatous appearance on histology.

    Allergic disorders are very common in the pediatric age group. While the exact etiology is unclear, evidence is mounting to incriminate environmental factors and an aberrant gut microbiota with a shift of the Th1/Th2 balance towards a Th2 response. Probiotics have been shown to modulate the immune system back to a Th1 response. Several in vitro studies suggest a role for probiotics in treating allergic disorders. Human trials demonstrate a limited benefit for the use of probiotics in atopic dermatitis in a preventive as well as a therapeutic capacity. Data supporting their use in allergic rhinitis are less robust. Currently, there is no role for probiotic therapy in the treatment of bronchial asthma. Future studies will be critical in determining the exact role of probiotics in allergic disorders. PMID:19946408

    The pathogenesis of allergic diseases entails an ineffective tolerogenic immune response to allergens. Regulatory T (Treg) cells play a key role in sustaining immune tolerance to allergens, yet mechanisms by which Treg cells fail to maintain tolerance in patients with 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 patients with allergic diseases: how Treg cells are essential in promoting tolerance to allergens but also how a proallergic inflammatory environment can skew Treg cells toward a pathogenic phenotype that aggravates and perpetuates disease. These advances highlight opportunities for novel therapeutic strategies that aim to re-establish tolerance in patients with chronic allergic diseases by promoting Treg cell stability and function.

    The history of allergic disease goes back to 1819, when Bostock described his own ‘periodical affection of the eyes and chest’, which he called ‘summer catarrh’. Since they thought it was produced by the effluvium of new hay, this condition was also called hay fever. Later, in 1873, Blackley established that pollen played an important role in the causation of hay fever. Nowadays, the definition of allergy is ‘An untoward physiologic event mediated by a variety of different immunologic reactions’. In this review, the term allergy will be restricted to the IgE-dependent reactions. The most important clinical manifestations of IgE-dependent reactions are allergic conjunctivitis, allergic rhinitis, allergic asthma and atopic dermatitis. However, this review will be restricted to allergic rhinitis. The histopathological features of allergic inflammation involve an increase in blood flow and vascular permeability, leading to plasma exudation and the formation of oedema. In addition, a cascade of events occurs which involves a variety of inflammatory cells. These inflammatory cells migrate under the influence of chemotactic agents to the site of injury and induce the process of repair. Several types of inflammatory cells have been implicated in the pathogenesis of allergic rhinitis. After specific or nonspecific stimuli, inflammatory mediators are generated from cells normally found in the nose, such as mast cells, antigen-presenting cells and epithelial cells (primary effector cells) and from cells recruited into the nose, such as basophils, eosinophils, lymphocytes, platelets and neutrophils (secondary effector cells). This review describes the identification of each of the inflammatory cells and their mediators which play a role in the perennial allergic processes in the nose of rhinitis patients. PMID:18475703

    Allergic rhinitis a chronic inflammatory disease of the upper airways that has a major impact on the quality of life of patients and is a socio-economic burden. Understanding the underlying immune mechanisms is central to developing better and more targeted therapies. The inflammatory response in the nasal mucosa includes an immediate IgE-mediated mast cell response as well as a latephase response characterized by recruitment of eosinophils, basophils, and T cells expressing Th2 cytokines including interleukin (IL)-4, a switch factor for IgE synthesis, and IL-5, an eosinophil growth factor and on-going allergic inflammation. Recent advances have suggested new pathways like local synthesis of IgE, the IgE-IgE receptor mast cell cascade in on-going allergic inflammation and the epithelial expression of cytokines that regulate Th2 cytokine responses (i.e., thymic stromal lymphopoietin, IL-25, and IL-33). In this review, we briefly review the conventional pathways in the pathophysiology of allergic rhinitis and then elaborate on the recent advances in the pathophysiology of allergic rhinitis. An improved understanding of the immune mechanisms of allergic rhinitis can provide a better insight on novel therapeutic targets. PMID:22053313

    Diagnosis early in life, sensitization, asthma endotypes, monitoring of disease and treatment progression are key motivations for the exploration of biomarkers for allergic rhinitis and allergic asthma. The number of genes related to allergic rhinitis and allergic asthma increases steadily; however, prognostic genes have not yet entered clinical application. We hypothesize that the combination of multiple genes may generate biomarkers with prognostic potential. The current review attempts to group more than 161 different potential biomarkers involved in respiratory inflammation to pave the way for future classifiers. The potential biomarkers are categorized into either epithelial or infiltrate-derived or mixed origin, epithelial biomarkers. Furthermore, surface markers were grouped into cell-type-specific categories. The current literature provides multiple biomarkers for potential asthma endotypes that are related to T-cell phenotypes such as Th1, Th2, Th9, Th17, Th22 and Tregs and their lead cytokines. Eosinophilic and neutrophilic asthma endotypes are also classified by epithelium-derived CCL-26 and osteopontin, respectively. There are currently about 20 epithelium-derived biomarkers exclusively derived from epithelium, which are likely to innovate biomarker panels as they are easy to sample. This article systematically reviews and categorizes genes and collects current evidence that may promote these biomarkers to become part of allergic rhinitis or allergic asthma classifiers with high prognostic value.

    Purpose of review To discuss the presence and role of neutrophils in asthma and allergic diseases, and outline importance of pollen and cat dander-induced innate neutrophil recruitment in induction of allergic sensitization and allergic inflammation. Recent findings Uncontrolled asthma is associated with elevated numbers of neutrophils, and levels of neutrophil-attracting chemokine IL-8 and IL-17 in BAL fluids. These parameters negatively correlate with lung function. Pollen allergens and cat dander recruit neutrophils to the airways in a TLR4, MD2 and CXCR2-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 TLR4, or siRNA against MD2 also inhibits allergic inflammation. The molecular mechanisms by which neutrophils shift the inflammatory response of the airways to inhaled allergens to an allergic phenotype is an area of active research. Summary Recent studies have revealed that neutrophil recruitment is important in development of allergic sensitization and inflammation. Inhibition of neutrophils recruitment may be strategy to control allergic inflammation. PMID:26694038

    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.

    Chronic granulomatous disease is an inherited immunodeficiency in which phagocytes fail to generate superoxide and its metabolites, resulting in severe recurrent infections and frequent hospitalizations. Chronic illness and frequent hospitalizations can affect growth and development as well as social and educational opportunities. Since no data have been reported on cognitive functioning in patients with this illness, the authors sought to examine cognitive function in a group of patients with chronic granulomatous disease. A retrospective chart review of 26 patients seen and followed at the National Institutes of Health who had received cognitive testing at the request of parent or staff was performed. Demographic information including medical, psychiatric, and developmental histories was gathered. Six patients (23%) were found to have an IQ of 70 or below, indicative of cognitive deficits, and all of those patients had defects in the membrane-linked cytochrome b558. The prevalence of cognitive deficits in this selected population of chronic granulomatous disease patients was high. The determination of the true distribution of cognitive functioning in the general chronic granulomatous disease population is important, since cognitive deficits have implications for educational planning and potential therapies such as transplantation and gene therapy in children.

    Feline infectious peritonitis (FIP) is a fatal, coronavirus (CoV)-induced systemic disease in cats, characterized by granulomas in organs and granulomatous vasculitis. This study describes the morphologic features of granulomatous vasculitis in FIP as well as its development in the course of monocyte-associated feline CoV (FCoV) viremia in five naturally infected Domestic Shorthair cats with FIP. Monocyte-associated FCoV viremia was demonstrated by immunohistology, RNA in situ hybridization, and electron micropscopy. Granulomatous phlebitis at different stages of development was observed. Vasculitic processes ranged from attachment and emigration of FCoV-infected monocytes to vascular/perivascular granulomatous infiltrates with destruction of the vascular basal lamina. Monocytes as well as perivascular macrophages were activated because they were strongly positive for CD18 and expressed cytokines (tumor necrosis factor-alpha and interleukin-1beta) and matrix metalloproteinase-9. In addition, general activation of endothelial cells, represented by major histocompatibility complex II upregulation, was observed in all cases. These results confirm FIP as a monocyte-triggered systemic disease and demonstrate the central role of activated monocytes in FIP vasculitis. PMID:15872378

    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

    In recent years, to the list of classic pet animals (dogs and cats) as allergens we must now add the "new pet animals" (NPAs). This group of animals, referred to by the Anglo-Saxons as "pets", includes both those previously recognized (rabbit, guinea pig, hamster, birds) and the "truly new NPAs"; by general agreement "NPA" will include all animals other than cats and dogs. Some rather rare animals are regularly added to this list. The emergence of "NPAs" can be related to a social phenomenon, in particular, to the fashion and need for the exotic (http://www.aquadesign.be). They are a very diverse group: warm-blooded animals, spiders, batrachia (frogs, toads, salamanders, etc.) and reptiles. Besides the physical risks from their natural aggressive behaviour, the "NPAs" can be an allergic risk factor and this risk has a tendency to increase. Allergists and paediatricians have a role to play in the diagnosis and prevention of these allergies by giving advice on the choice of pet animals. This review concerns allergies to rodents, reptiles, batrachians, spiders, etc. PMID:19195854

  11. The burden of allergic rhinitis.

    Nathan, Robert A

    2007-01-01

    Although formerly regarded as a nuisance disease, allergic rhinitis (AR) has a considerable effect on quality of life and can have significant consequences if left untreated. The total burden of this disease lies not only in impaired physical and social functioning but also in a financial burden made greater when considering evidence that AR is a possible causal factor in comorbid diseases such as asthma or sinusitis. Compared with matched controls, patients with AR have an approximate twofold increase in medication costs and 1.8-fold the number of visits to health practitioners. Hidden direct costs include the treatment of comorbid asthma, chronic sinusitis, otitis media, upper respiratory infection, and nasal polyposis. Nasal congestion, the most prominent symptom in AR, is associated with sleep-disordered breathing, a condition that can have a profound effect on mental health, including increased psychiatric disorders, depression, anxiety, and alcohol abuse. Furthermore, sleep-disordered breathing in childhood and adolescence is associated with increased disorders of learning performance, behavior, and attention. In the United States, AR results in 3.5 million lost workdays and 2 million lost schooldays annually. Patients struggle to alleviate their misery, frequently self-adjusting their treatment regimen of over-the-counter and prescription medications because of lack of efficacy, deterioration of efficacy, lack of 24-hour relief, and bothersome side effects. Ironically, health care providers overestimate patient satisfaction with therapy. Therefore, improvement in patient-practitioner communication may enhance patient adherence with prescribed regimens.

  12. Surfactant and allergic airway inflammation.

    PubMed

    Winkler, Carla; Hohlfeld, Jens M

    2013-01-01

    Pulmonary surfactant is a complex mixture of unique proteins and lipids that covers the airway lumen. Surfactant prevents alveolar collapse and maintains airway patency by reducing surface tension at the air-liquid interface. Furthermore, it provides a defence against antigen uptake by binding foreign particles and enhancing cellular immune responses. Allergic asthma is associated with chronic airway inflammation and presents with episodes of airway narrowing. The pulmonary inflammation and bronchoconstriction can be triggered by exposure to allergens or pathogens present in the inhaled air. Pulmonary surfactant has the potential to interact with various immune cells which orchestrate allergen- or pathogen-driven episodes of airway inflammation. The complex nature of surfactant allows multiple sites of interaction, but also makes it susceptible to external alterations, which potentially impair its function. This duality of modulating airway physiology and immunology during inflammatory conditions, while at the same time being prone to alterations accompanied by restricted function, has stimulated numerous studies in recent decades, which are reviewed in this article.

    Natural killer (NK) cells are cytotoxic cells that are able to rapidly kill viruses, tumor cells, parasites, bacteria, and even cells considered “self”. The activity of NK cells is controlled by a fine balance of inhibitory and activating signals mediated by a complex set of different receptors. However, the function of NK cells is not restricted only to the killing of target cells, NK cells also possess other properties such as the secretion of proangiogenic factors during pregnancy. Here, we demonstrate another unique NK-cell activity, namely the regulation of T-cell mediated allergic responses, which is dependent on the NK-cell specific receptor NKp46 (Ncr1 in mice). Using mice in which the Ncr1 gene has been replaced with a green fluorescent protein, we demonstrate reduced delayed-type hypersensitivity and airway hypersensitivity. Interestingly, we show that this reduction in airway hypersensitivity is due to differences in the stimulation of T cells resulting in an altered cytokine profile. PMID:23878025

    2015-10-01

    Eosinophilic oesophagitis (EoE) is characterized by oesophageal dysfunction and oesophageal eosinophilia refractory to proton-pump-inhibitor treatment. EoE is a food allergy, as elimination of food trigger(s) abrogates the disease, while trigger reintroduction causes recurrence. The allergic mechanism of EoE involves both IgE and non-IgE processes. There is a break in oral tolerance, the immune mechanism allowing enteric exposure to food and micro-organisms without causing deleterious immune responses. Changes in life-style, alterations in gut flora and use of antibiotics may be increasing disease prevalence. Mouse models of EoE and human studies revealed the role of regulatory T-cells and iNKT-cells in the pathogenesis. Th2-cytokines like IL-4, IL-5 and IL-13, and other cytokines like TGFβ and TSLP are involved, but perhaps no one cytokine is critically important for driving the disease. Control of EoE may require a pharmaceutical approach that blocks more than one target in the Th2-inflammatory pathway. PMID:26552770

    Allergic rhinitis (AR), the most common chronic disease in childhood is often ignored, misdiagnosed and/or mistreated. Undertreated AR impairs quality of life, exacerbates asthma and is a major factor in asthma development. It can involve the nose itself, as well as the organs connected with the nose manifesting a variety of symptoms. Evidence-based guidelines for AR therapy improve disease control. Recently, paediatric AR guidelines have been published by the European Academy of Allergy and Clinical Immunology and are available online, as are a patient care pathway for children with AR and asthma from the Royal College of Paediatrics and Child Health. Management involves diagnosis, followed by avoidance of relevant allergens, with additional pharmacotherapy needed for most sufferers. This ranges, according to severity, from saline sprays, through non-sedating antihistamines, oral or topical, with minimally bioavailable intranasal corticosteroids for moderate/severe disease, possibly plus additional antihistamine or antileukotriene. The concept of rhinitis control is emerging, but there is no universally accepted definition. Where pharmacotherapy fails, allergen-specific immunotherapy, which is uniquely able to alter long-term disease outcomes, should be considered. The subcutaneous form (subcutaneous immunotherapy) in children has been underused because of concerns regarding safety and acceptability of injections. Sublingual immunotherapy is both efficacious and safe for grass pollen allergy. Further studies on other allergens in children are needed. Patient, carer and practitioner education into AR and its treatment are a vital part of management. PMID:25838332

    The parenchymal lung diseases caused by metal inhalation include interstitial fibrosis, giant cell interstitial pneumonitis, chemical pneumonitis, and granulomatous disease, among others. We reported two cases of granulomatous lung disease with occupational exposure to metal dusts other than beryllium. They had worked in the battery manufacturing industry for 7 years and in an aluminum-processing factory for 6 years, respectively. Chest high-resolution computed tomography showed diffuse micronodules, and histology of video-assisted lung biopsy specimens revealed granulomatous lesions in the pulmonary interstitium. Results of microscopic examination of the tissue with special stains for mycobacteria and fungi were negative. Analysis by an electron probe microanalyzer with a wavelength-dispersive spectrometer (EPMA-WDS) confirmed the presence of silicon, iron, aluminum, and titanium in the granulomas. In particular, aluminum was distributed in a relatively high concentration in the granulomatous lesions. Although chronic beryllium disease is well known as an occupational granulomatous lung disease, much less is known about the other metals that cause granulomatous reactions in humans. Our report pointed out manifestations similar to beryllium disease after other metal dust exposures, in particular aluminum exposure. To our knowledge, this is the first report showing two-dimensional images of elemental mapping in granulomatous lesions associated with metal inhalation using EPMA-WDS. PMID:27330955

    We established a murine model of multiwall carbon nanotube (MWCNT)-induced chronic granulomatous disease, which resembles human sarcoidosis pathology. At 60 days after oropharyngeal MWCNT instillation, bronchoalveolar lavage (BAL) cells from wild-type mice exhibit an M1 phenotype with elevated proinflammatory cytokines and reduced peroxisome proliferator-activated receptor γ (PPARγ)-characteristics also present in human sarcoidosis. Based upon MWCNT-associated PPARγ deficiency, we hypothesized that the PPARγ target gene, ATP-binding cassette (ABC) G1, a lipid transporter with antiinflammatory properties, might also be repressed. Results after MWCNT instillation indicated significantly repressed ABCG1, but, surprisingly, lipid transporter ABCA1 was also repressed, suggesting a possible second pathway. Exploration of potential regulators revealed that microRNA (miR)-33, a lipid transporter regulator, was strikingly elevated (13.9 fold) in BAL cells from MWCNT-instilled mice but not sham control mice. Elevated miR-33 was also detected in murine granulomatous lung tissue. In vitro studies confirmed that lentivirus-miR-33 overexpression repressed both ABCA1 and ABCG1 (but not PPARγ) in cultured murine alveolar macrophages. BAL cells of patients with sarcoidosis also displayed elevated miR-33 together with reduced ABCA1 and ABCG1 messenger RNA and protein compared with healthy control subjects. Moreover, miR-33 was elevated within sarcoidosis granulomatous tissue. The findings suggest that alveolar macrophage miR-33 is up-regulated by proinflammatory cytokines and may perpetuate chronic inflammatory granulomatous disease by repressing antiinflammatory functions of ABCA1 and ABCG1 lipid transporters. The results also suggest two possible pathways for transporter dysregulation in granulomatous disease-one associated with intrinsic PPARγ status and the other with miR-33 up-regulation triggered by environmental challenges, such as MWCNT.

    Granulomatous disorders are chronic cell-mediated immune responses histologically characterized by collections of macrophages, epithelioid cells, and multinucleated giant cells. This disease spectrum often has an infectious origin, but sometimes neither an infective agent nor an inciting antigenic stimulus can be identified. The skin may be a preferential target for these disorders, especially in the areas that have been damaged by various forms of skin injury (eg, herpetic infections, trauma, thermal or solar burns, vaccinations, tattoos). These damaged skin sites frame the new concept of an immunocompromised cutaneous district (ICD), which defines a skin area with acquired immune dysregulation that can pave the way for the local onset of opportunistic disorders, such as infections, tumors, and granulomatous disorders. Sarcoidosis, granuloma annulare (GA), and forms of granulomatous vasculitis, such as Churg-Strauss syndrome (CSS) and Wegener's granulomatosis (WG), are the most common granulomatous disorders that occur in an ICD and may share common pathogenic mechanisms. Recent studies have found clinical and pathologic overlapping features across noninfectious granulomas. Although no unifying etiology exists, the development of granulomatous processes in the ICD has often been reported and the literature contains various hypotheses to explain it: (1) overactive immune response in a previously injured region with or without loss of immune tolerance; (2) overall reduced immune response; (3) retention of an exogeneous antigen or foreign body; (4) altered neural signaling; and (5) a combination of all the aforementioned processes. T helper cells, T regulatory cells, and macrophages, as well as a number of antigenic proteins, have been identified as potential contributing factors. In addition, a genetic predisposition and an intact systemic immune system are both instrumental for the persistence of local granuloma formation in the ICD. PMID:25160106

  20. Beta-escin has potent anti-allergic efficacy and reduces allergic airway inflammation

    PubMed Central

    2010-01-01

    Background Type I hypersensitivity is characterized by the overreaction of the immune system against otherwise innocuous substances. It manifests as allergic rhinitis, allergic conjunctivitis, allergic asthma or atopic dermatitis if mast cells are activated in the respective organs. In case of systemic mast cell activation, life-threatening anaphylaxis may occur. Currently, type I hypersensitivities are treated either with glucocorticoids, anti-histamines, or mast cell stabilizers. Although these drugs exert a strong anti-allergic effect, their long-term use may be problematic due to their side-effects. Results In the course of a routine in vitro screening process, we identified beta-escin as a potentially anti-allergic compound. Here we tested beta-escin in two mouse models to confirm this anti-allergic effect in vivo. In a model of the early phase of allergic reactions, the murine passive cutaneous anaphylaxis model, beta-escin inhibited the effects of mast cell activation and degranulation in the skin and dose-dependently prevented the extravasation of fluids into the tissue. Beta-escin also significantly inhibited the late response after antigen challenge in a lung allergy model with ovalbumin-sensitized mice. Allergic airway inflammation was suppressed, which was exemplified by the reduction of leucocytes, eosinophils, IL-5 and IL-13 in the bronchoalveolar lavage fluid. Histopathological examinations further confirmed the reduced inflammation of the lung tissue. In both models, the inhibitory effect of beta-escin was comparable to the benchmark dexamethasone. Conclusions We demonstrated in two independent murine models of type I hypersensitivity that beta-escin has potent anti-allergic properties. These results and the excellent safety profile of beta-escin suggest a therapeutic potential of this compound for a novel treatment of allergic diseases. PMID:20487574

  1. Epigenetic regulation of asthma and allergic disease

    PubMed Central

    2014-01-01

    Epigenetics of asthma and allergic disease is a field that has expanded greatly in the last decade. Previously thought only in terms of cell differentiation, it is now evident the epigenetics regulate many processes. With T cell activation, commitment toward an allergic phenotype is tightly regulated by DNA methylation and histone modifications at the Th2 locus control region. When normal epigenetic control is disturbed, either experimentally or by environmental exposures, Th1/Th2 balance can be affected. Epigenetic marks are not only transferred to daughter cells with cell replication but they can also be inherited through generations. In animal models, with constant environmental pressure, epigenetically determined phenotypes are amplified through generations and can last up to 2 generations after the environment is back to normal. In this review on the epigenetic regulation of asthma and allergic diseases we review basic epigenetic mechanisms and discuss the epigenetic control of Th2 cells. We then cover the transgenerational inheritance model of epigenetic traits and discuss how this could relate the amplification of asthma and allergic disease prevalence and severity through the last decades. Finally, we discuss recent epigenetic association studies for allergic phenotypes and related environmental risk factors as well as potential underlying mechanisms for these associations.

  2. Allergic and asthmatic reactions to alcoholic drinks.

    Alcoholic drinks are capable of triggering a wide range of allergic and allergic-like responses, including rhinitis, itching, facial swelling, headache, cough and asthma. Limited epidemiological data suggests that many individuals are affected and that sensitivities occur to a variety of drinks, including wine, beer and spirits. In surveys of asthmatics, over 40% reported the triggering of allergic or allergic-like symptoms following alcoholic drink consumption and 30 - 35% reported worsening of their asthma. Sensitivity to ethanol itself can play a role in triggering adverse responses, particularly in Asians, which is due mainly to a reduced capacity to metabolize acetaldehyde. In Caucasians, specific non-alcohol components are the main cause of sensitivities to alcoholic drinks. Allergic sensitivities to specific components of beer, spirits and distilled liquors have been described. Wine is clearly the most commonly reported trigger for adverse responses. Sensitivities to wine appear to be due mainly to pharmacological intolerances to specific components, such as biogenic amines and the sulphite additives. Histamine in wine has been associated with the triggering of a wide spectrum of adverse symptoms, including sneezing, rhinitis, itching, flushing, headache and asthma. The sulphite additives in wine have been associated with triggering asthmatic responses. Clinical studies have confirmed sensitivities to the sulphites in wine in limited numbers of individuals, but the extent to which the sulphites contribute to wine sensitivity overall is not clear. The aetiology of wine-induced asthmatic responses may be complex and may involve several co-factors. PMID:12745410

  3. Chlorination products: emerging links with allergic diseases.

    2007-01-01

    Exposure of the human population to chlorination products has considerably increased during the 20(th) century especially after the 1960s with the development of public and leisure pools. The present article summarizes current knowledge regarding the human exposure to chlorination products and reviews studies suggesting that these chemicals might be involved in the development or exacerbation of allergic diseases. Populations regularly in contact with chlorination products such as swimmers, lifeguards or workers using chlorine as cleaning or bleaching agent show increased risks of allergic diseases or of respiratory disorders frequently associated with allergy. Experimental evidence suggests that chlorination products promote allergic sensitization by compromising the permeability or the immunoregulatory function of epithelial barriers. These findings led to the chlorine hypothesis proposing that the rise of allergic diseases could result less from the declining exposure to microbial agents (the hygiene hypothesis) than from the increasing and largely uncontrolled exposure to products of chlorination, the most widely used method to achieve hygiene in the developed world. Giving the increasing popularity of water recreational areas, there is an obvious need to assess the effects of chlorine-based oxidants on human health and their possible implication in the epidemic of allergic diseases.

    The prevalence of asthma and other allergic diseases is still increasing both in developed and developing countries. Allergic sensitization against common inhalant allergens is common and, although not sufficient, a necessary step in the development of allergic diseases. Despite a small number of proteins from certain plants and animals being common allergens in humans, we still do not fully understand who will develop sensitization and to which allergens. Environmental exposure to these allergens is essential for the development of sensitization, but what has emerged clearly in the literature in the recent years is that the adjuvants to which an individual is exposed at the same time as the allergen are probably an equally important determinant of the immune response to the allergen. These adjuvants act on all steps in the development of sensitization from modifying epithelial barriers, to facilitating antigen presentation, to driving T-cell responses, to altering mast cell and basophil hyperreactivity. The adjuvants come from biogenic sources, including microbes and the plants and animals that produce the allergens, and from man-made sources (anthropogenic), including unintended by-products of combustion and chemicals now ubiquitous in modern life. As we better understand how individuals are exposed to these adjuvants and how the exposure influences the likelihood of an allergic response, we may be able to design individual and community-level interventions that will reverse the increase in allergic disease prevalence, but we are not there yet.

    Allergic- and non-allergic rhinitis are very common diseases in childhood in industrialized countries. Although these conditions are widely trivialized by both parents and physicians they induce a major impact on quality of life for the affected children and a substantial drainage of health care resources. Unfortunately, diagnostic specificity is hampered by nonspecific symptom history and lack of reliable diagnostic tests which may explain why the pathology behind such diagnoses is poorly understood. Improved understanding of the pathophysiology of allergic- and non-allergic rhinitis in young children may contribute to the discovery of new mechanisms involved in pathogenesis and help direct future research to develop correctly timed preventive measures as well as adequate monitoring and treatment of children with rhinitis. Asthma is a common comorbidity in subjects with allergic rhinitis and epidemiological surveys have suggested a close connection between upper and lower airway diseases expressed as the "united airways concept". Furthermore, an association between upper and lower airway diseases also seems to exist in non-atopic individuals. Nevertheless, the nature of this association is poorly understood and there is a paucity of data objectivizing this association in young children. The aim of this thesis was to describe pathology in the upper and lower airways in young children from the COPSAC birth cohort with investigator-diagnosed allergic- and non-allergic rhinitis. Nasal congestion is a key symptom in both allergic- and non-allergic rhinitis, and eosinophilic inflammation is a hallmark of the allergic diseases. In paper I, we studied nasal eosinophilia and nasal airway patency assessed by acoustic rhinometry in children with allergic rhinitis, non-allergic rhinitis and healthy controls. Allergic rhinitis was significantly associated with nasal eosinophilia and irreversible nasal airway obstruction suggesting chronic inflammation and structural remodeling

  9. Allergic contact dermatitis from oxygen cannulas.

    PubMed

    McLaughlin, A J

    1980-10-01

    A patient experienced allergic contact dermatitis on two occasions two months apart as a result of wearing the same brand of polyvinyl chloride oxygen cannula. In one instance the cannula was removed and not replaced, as continuing oxygen was unnecessary; on the other occasion the original cannula was replaced by a cannula of another brand. In both cases the dermatitis disappeared after removal of the original cannula. The reaction was probably to a resin remaining in the polyvinyl chloride after the curing process in the manufacture of the plastic from which the cannula was made. Allergic reactions to plastics have been documented in other medical products but have not previously been reported in respiratory therapy plastic appliances. Because of variability in residual resins in different brands and batches of plastics, and because of varying individual sensitivity, therapists and others should be alert to the possibility of allergic contact dermatitis from respiratory therapy devices.

    2015-06-01

    Increasing evidence suggests an important role for platelets and their products (e.g., platelet factor 4, β-thromboglobulin, RANTES, thromboxane, or serotonin) in the pathogenesis of allergic diseases. A variety of changes in platelet function have been observed in patients with asthma, such as alterations in platelet secretion, expression of surface molecules, aggregation, and adhesion. Moreover, platelets have been found to actively contribute to most of the characteristic features of asthma, including bronchial hyperresponsiveness, bronchoconstriction, airway inflammation, and airway remodeling. This review brings together the current available data from both experimental and clinical studies that have investigated the role of platelets in allergic airway inflammation and asthma. It is anticipated that a better understanding of the role of platelets in the pathogenesis of asthma might lead to novel promising therapeutic approaches in the treatment of allergic airway diseases.

    Genetic predisposition and indoor exposure to allergens-especially during the very early childhood years are major factors for the development of allergic diseases later in life. The present study analyzed the association between allergic sensitization in children aged 5 to 14 years and residing since birth in homes of different building types. A cross-sectional study of 811 children aged 5 to 14 years who resided in the same home since birth investigated indoor factors using a questionnaire and allergic sensitization assessed by skin prick test. The prevalence of allergic sensitization was compared between children who lived since birth in five different building types. After adjustment for age, gender, parental education and study area the odds of allergic sensitization were higher among children who lived in prefabricated concrete slab buildings built after 1970 (OR 1.56, 95% CI: 1.02-2.38) and among children who lived in new brick buildings (OR 1.75, 95% CI: 0.88-3.47) than among children who lived in old brick buildings. Moreover, the odds of pollen sensitization was higher among children who lived in the new building types (prefabricated slab buildings: OR 1.68, 95% CI: 1.04-2.72; new brick buildings: OR 1.48, 95% CI: 0.64-3.42) while living in timber-framed houses was associated with a higher odds of sensitization against mites (OR 1.63, 95% CI: 0.77-3.44). The step by step inclusion of single indoor factors like type of heating, numbers of building storeys, number of persons per room, environmental tobacco smoke, use of gas for cooking purposes, dampness of the home or visible moulds in the logistic regression model only marginally changed the odds ratios. Modern living conditions are associated with a higher odds of allergic sensitization. PMID:9789357

    Background: The united allergic airway is a theory that connects allergic rhinitis (AR), chronic rhinosinusitis, and asthma, in which seemingly disparate diseases, instead of being thought of separately, are instead viewed as arising from a common atopic entity. Objective: This article describes patients with such diseases; explores ideas suggesting a unified pathogenesis; elucidates the various treatment modalities available, emphasizing nasal corticosteroids and antihistamines; and provides an update of the literature. Methods: A literature review was conducted. Conclusion: The aggregation of research suggests that AR, asthma, and chronic rhinosinusitis are linked by the united allergic airway, a notion that encompasses commonalities in pathophysiology, epidemiology, and treatment.

    We suggest a new micro cell isolation column of basophils for an allergic diagnostic system for detecting human basophils activations. Surface plasmon resonance imaging (SPRI) biosensors using human basophils allow allergic diagnosis of less than 1 ml of peripheral blood. However, an isolation of basophils from a small amount of blood is not easy. In this study, we constructed a new micro cell isolation column for basophils with poly(dimethylsiloxane) (PDMS) microflow pass including magnetic particles. Furthermore, we determined whether leukocytes were captured by the micro cell isolation column from a small amount of blood. We can isolate basophils from other leukocytes by using the micro cell isolation column.

    Histamine is the primary mediator involved the pathophysiology of allergic rhinitis and chronic urticaria, and this explains the prominent role that histamine H(1)-receptor antagonists have in the treatment of these disorders. However, histamine is clearly not the only mediator involved in the inflammatory cascade. There is an emerging view that drugs which can inhibit a broader range of inflammatory processes may prove to be more effective in providing symptomatic relief in both allergic rhinitis and chronic urticaria. This is an important consideration of the Allergic Rhinitis and its Impact on Asthma (ARIA) initiative which provides a scientific basis for defining what are the desirable properties of an 'ideal' antihistamine. In this review of rupatadine, a newer dual inhibitor of histamine H(1)- and PAF-receptors, we evaluate the evidence for a mechanism of action which includes anti-inflammatory effects in addition to a powerful inhibition of H(1)- and PAF-receptors. We assess this in relation to the clinical efficacy (particularly the speed of onset of action) and safety of rupatadine, and importantly its longer term utility in everyday life. In clinical trials, rupatadine has been shown to be an effective and well-tolerated treatment for allergic rhinitis and chronic idiopathic urticaria (CIU). It has a fast onset of action, producing rapid symptomatic relief, and it also has an extended duration of clinical activity which allows once-daily administration. In comparative clinical trials rupatadine was shown to be at least as effective as drugs such as loratadine, cetirizine, desloratadine and ebastine in reducing allergic symptoms in adult/adolescent patients with seasonal, perennial or persistent allergic rhinitis. Importantly, rupatadine demonstrated no adverse cardiovascular effects in preclinical or extensive clinical testing, nor negative significant effects on cognition or psychomotor performance (including a practical driving study).

    Background: Granulomatous dermatoses are common skin pathology, often need histopathological confirmation for diagnosis. Histologically six sub-types of granulomas found in granulomatous skin diseases- tuberculoid, sarcoidal, necrobiotic, suppurative, foreign body & histoid type. The aims of the present study were clinico-pathological evaluation of granulomatous skin lesions and their etiological classification based on histopathological examination. Methods: It was a five years (Jan 2009- Dec 2013) retrospective study involving all the skin biopsies. Detailed clinical and histopathological features were analyzed and granulomatous skin lesions were categorized according to type of granuloma & etiology. Special stains were used in few cases for diagnostic purpose. Results: Among 1280 skin biopsies, 186 cases (14.53%) were granulomatous skin lesions with a ratio 1:24. In histopathological sub-typing, tuberculoid granuloma was most common type (126 cases, 67.74%). Most common etiology of granuloma in the study was leprosy (107 cases, 57.52%). Other etiologies were cutaneous tuberculosis, foreign body granulomas, fungal lesions, cutaneous leishmaniasis, sarcoidosis and granuloma annulare. Conclusion: Histopathology is established as gold standard investigation for diagnosis, categorization and clinico-pathological correlation of granulomatous skin lesions. PMID:26870144

    Physical and psychological stressors have been implicated in acute asthma exacerbation. The objective of the current study was to determine the effects of forced swimming stress (FST) on allergic pulmonary inflammation in BALB/c mice. Eighty female mice were allocated to one of four treatments arranged in a 2 x 2 factorial consisting of two levels of allergy and two levels of stress. The effects of stress and allergy were assessed by examination of cytokines and leukocyte differentials in the bronchoalveolar lavage fluid, corticosterone and immunoglobulin (Ig) E in the plasma, leukocyte differentials in the peripheral blood, natural killer cytotoxicity, and histopathology of the lungs. Behavior was recorded during the FST. Stress and allergy increased plasma corticosterone in mice. Allergy increased IgE concentrations and pulmonary inflammation. Interleukin-4 was greater among allergic stressed and non-stressed mice and stressed, non-allergic mice compared with non-stressed, non-allergic mice. Interleukin-5 (IL-5) and 6 (IL-6) were greater among allergic stressed and non-stressed mice compared with non-allergic mice. Interleukin-5 and 6 were reduced among stressed-allergic mice compared with non-stressed, allergic mice. Stress and allergy shifted mice towards a T-helper 2 response as shown by increased interleukin-4. Stress reduced IL-5 and IL-6 in allergic mice but not non-allergic mice. Pulmonary inflammation was not reduced among allergic stressed mice in spite of elevated glucocorticoids. Mice induced to be allergic responded to FST differently than non-allergic mice. Our findings suggest that stress induces a differential response among allergic and non-allergic mice. PMID:19527741

At the National Institute of Pediatrics of Mexico a project for facilitating the diagnosis of the disease was implemented by us in 2009. From the start of such project up to date 68 cases have been studied; 80% of those are X-linked forms (LX) and moreover, it has become noticeable the diagnosis at a younger age. The new challenge we are facing its to provide a successful treatment to those patients diagnosed with chronic granulomatous disease (CGD). We are reporting the case of a one-month old newborn patient diagnosed with CGD-LX that was successfully transplanted in Mexico. PMID:26943834

    In this review we focus on 2 of the noninfectious granulomatous dermatitides, granuloma annulare and interstitial granulomatous dermatitis (the remaining 6 will be discussed in Parts 2 and 3), with an overview of their clinical and histological presentations, differential diagnoses, and treatment options. The disorders we discuss are polymorphic in their clinical and histopathological presentations, follow chronic or undulating disease courses, and are typically recalcitrant to therapeutic interventions. Although the clinical history may be helpful, careful and thorough histopathological examination is required. Established treatment algorithms for these disorders are lacking, and no randomized, placebo-controlled studies have been published. Future investigations should focus on the evaluation of larger cohorts, not only to establish treatment recommendations in randomized, placebo-controlled trials, but also to reach a greater understanding of disease pathogenesis and clinical-pathological presentation.

    Scleromyxedema is the generalized and sclerodermoid form of lichen myxedematosus. Its typical histological features include a diffuse deposition of mucin in the papillary and mid reticular dermis, an increased of collagen deposition, and a proliferation of irregularly arranged fibroblasts. We describe a 76-year-old man presenting with scleromyxedema associated with IgGlambda monoclonal gammopathy whose biopsy showed histological features of an interstitial granulomatous-like process consistent with interstitial granuloma annulare. The significance of these unusual granulomatous findings in the setting of scleromyxedema are unknown and have been described only once in the literature. This observation expands the spectrum of scleromyxedema and highlights the difficulty in diagnosing this disabling condition. PMID:19638067

    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. PMID:27391977

    This paper presents a case history and discussion of a man with an autosomal recessive form of chronic granulomatous disease (CGD) of childhood. Because studies indicated that this patient's monocytes increased production of superoxide after in vitro stimulation with recombinant human interferon gamma, he received subcutaneous injections every other day. Steady improvement resulted. The importance of oxidative metabolism has prompted considerable attention to a group of patients with disorders of phagocyte oxidative metabolism, known as the CGDs of childhood.

    Chronic granulomatous disease (CGD) often presents with infectious illness, such as repeating bacterial and fungal infections, due to the inability to generate superoxide, which would destroy certain infectious pathogens, and is usually diagnosed in childhood. We describe a CGD case diagnosed in neonatal period, who initially presented with invasive aspergillosis. Neonatal invasive pulmonary aspergillosis is very rare and, to the best of our knowledge, this might be the youngest case in Japan. PMID:24674387

    Sporothrix schenckii lymphadenitis was identified in a 33 month old male with X-linked chronic granulomatous disease (CGD). S. schenckii is a dimorphic catalase producing fungus found in the soil of temperate and tropical climates. Host defense against S. schenckii relies primarily on innate and cellular responses and gp91(phox-/-) mice are susceptible to disseminated infection. This case represents the first report of susceptibility to sporotrichosis in a patient with CGD. PMID:24241583

    Patients with chronic granulomatous disease are predisposed to fungal infections and are therefore routinely prescribed antifungal prophylaxis. We report a case where acremonium was responsible for causing a cutaneous infection (mycetoma) despite antifungal prophylaxis. Treatment with voriconazole was initiated and the infection gradually resolved. This case highlights the need for careful clinical follow-up and thorough investigation of patients who have a neutrophil immunodeficiency. PMID:27022493

    Granulomatous amoebic encephalitis due to Acanthamoeba is a chronic disease that almost always results in death. Hematogenous spread is a pre-requisite followed by amoebae invasion of the blood-brain barrier to enter the central nervous system. Given the systemic nature of this infection, a significant latent period of several months before the appearance of clinical manifestations is puzzling. Based on reported cases, here we propose pathogenetic mechanisms that explain the above described latency of the disease. PMID:26276705

  11. A dual role for complement in allergic asthma.

    PubMed

    2007-06-01

    Complement is an ancient danger-sensor system of innate immunity, providing first-line defence against pathogens. Concordant with its pro-inflammatory properties, complement contributes to airway inflammation, hyperresponsiveness and mucus production during the effector phase of allergic asthma. In contrast to these pro-allergic properties, complement can also protect from the development of the maladaptive Th2-biased immune response that drives airway inflammation and hyperreactivity in allergic asthma. As such, selective targeting of pro-allergic complement pathways appears an attractive therapeutic option in allergic asthma. PMID:17475559

    Granulomatous slack skin (GSS) represents an extremely rare variant of mycosis fungoides with only 70 cases reported in the literature to date. It is characterized clinically by the occurrence of bulky, pendulous skinfolds, usually located in flexural areas and histologically by an infiltrate composed of small neoplastic T-lymphocytes joined by granulomatous inflammation with scattered multinucleated giant cells containing nuclei arranged in a wreath-like fashion. Since its first description, very rare cases of GSS with muscle involvement, large vessels involvement, or necrobiotic changes have been reported. We present an extraordinary case of GSS with all these unusual features developing in the lesions of the same patient. The long follow-up of seven years allowed us to document the evolution of each lesion. Some lesions appeared and evolved in a manner very reminiscent of those of "parapsoriasis en plaques", others were classical GSS lesions, and still others developed large ulcerated lesions. These ulcerated lesions consistently failed to respond to conventional wound therapy, skin directed therapy [retinoids + psoralen combined with ultraviolet A (PUVA)-therapy], and interferon-alpha therapy. Remarkably, the ulcers completely healed when systemic corticosteroids were added. We hence postulate that the ulcers appeared because of large vessel vasculitis rather than tumoral direct destruction. PMID:27516031

    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 pathogenesis 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.

  14. Bilastine: in allergic rhinitis and urticaria.

    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.

    Skin dynamic termography supplemented by a mathematical model is presented as an objective and sensitive indicator of the skin prick test result. Termographic measurements were performed simultaneously with routine skin prick tests. The IR images were acquired every 70 s up to 910 s after skin prick. In the model histamine is treated as the principal mediator of the allergic reaction. Histamine produces vasolidation and the engorged vessels are responsible for an increase in skin temperature. The model parameters were determined by fitting the analytical solutions to the spatio-temporal distributions of the differences between measured and baseline temperatures. The model reproduces experimental data very well (coefficient of determination = 0.805÷0.995). The method offers a set of parameters to describe separately skin allergic reaction and skin reactivity. The release of histamine after allergen injection is the best indicator of allergic response. The diagnostic parameter better correlates with the standard evaluation of a skin prick test (correlation coefficient = 0.98) than the result of the thermographic planimetric method based on temperature and heated area determination (0.81). The high sensitivity of the method allows for determination of the allergic response in patients with the reduced skin reactivity.

    1987-04-01

    A few patients (6-7%) with a verified type I allergic reaction do not respond with histamine release after challenge of their basophils with specific antigen (non-responding basophils from allergic patients). Sera from these non-responding patients were used for passive sensitization of responding cells from healthy controls. When these sensitized cells were challenged with specific antigen, histamine release was observed indicating that the non-responding allergic patients have circulating antigen-specific IgE capable of binding to Fc-receptors on the basophils. These findings suggest the possibility that non-responding basophils have impaired cell functions. We therefore examined the influence of enhanced IgE receptor stimulation on histamine release in non-responding basophils. This was made by stimulating protein kinase C activity by a phorbol ester (phorbol 12-myristate 13-acetate). When the non-responding cells were incubated with the phorbol ester and challenged with either anti-IgE or specific antigen, the cells released histamine. These findings support the hypothesis that the unresponsiveness of basophils in some allergic patients is associated with impaired IgE receptor complex activation or subcellular functioning and not with a lack of cell-bound IgE.

    BACKGROUND AND AIMS: Interleukin 10 (IL10) inhibits monocyte/macrophage and T lymphocyte effector functions. This study examined the effect of systemically administered IL10 on acute and chronic granulomatous enterocolitis, hepatitis, and arthritis in a rat model. METHODS: Lewis rats were injected intramurally with streptococcal peptidoglycan-polysaccharide (PG-APS) polymers. Beginning 12 hours before PG-APS injection, rats were treated daily with subcutaneous murine recombinant IL10 or vehicle for three or 17 days. RESULTS: IL10 attenuated acute enterocolitis in a dose dependent fashion (p < 0.01). Protective effects were more profound in the chronic granulomatous phase with decreased enterocolitis and markedly inhibited leucocytosis, hepatic granulomas, and chronic erosive arthritis (p < 0.001). IL10 downregulated tissue IL1, IL6, tumour necrosis factor alpha, and interferon gamma gene expression, consistent with the in vitro effects of IL10 on PG-APS-stimulated splenocytes. Caecal IL1 protein concentrations and IL2 and interferon gamma secretion by in vitro stimulated mesenteric lymph nodes were downregulated in IL10 treated animals. CONCLUSIONS: These results indicate that exogenous IL10 can inhibit experimental granulomatous inflammatory responses and suggest that IL10 treatment could be an effective new therapeutic approach in human disorders such as Crohn's disease, rheumatoid arthritis, and sarcoidosis.

    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.

    Idiopathic granulomatous myocarditis is extremely rare, particularly since the introduction of drugs effective against tuberculosis (TB), viruses, fungi and the effective treatment of sarcoidosis. Here is a case of a 65-year-old female prisoner having history of sudden collapse and ultimately death. Autopsy findings of various viscera on histopathological examination show granulomatous pathology, that is, in spleen, liver and in the left ventricular wall of heart. Ziehl-Neelsen staining of the sections show the absence of acid fast bacilli, negative for fungal staining as most of the granulomas are noncaseating type with presence of giant cells having no asteroid body and Schuamann body, real-time polymerase chain reaction for TB is negative. Idiopathic giant cell myocarditis is a disease of relatively young adults, that is, between 3 rd and 4 th decade of life. So, this case is strongly considered to be a case of sudden death due to myocarditis as a result of idiopathic systemic granulomatous pathology, a rare case in in literature. PMID:25673606

    Granulomatous interstitial nephritis (GIN) is an uncommon pathologic lesion encountered in 0.5% to 5.9% of renal biopsies. Drugs, sarcoidosis, and infections are responsible for most cases of GIN. Malignancy is not an established cause of GIN. Here, we report a series of 5 patients with GIN secondary to chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). Patients were mostly elderly white males with an established history of CLL/SLL who presented with severe renal impairment (median peak serum creatinine, 7.3 mg/dL), leukocyturia, and mild proteinuria. One had nephromegaly. In 2 patients, the development and relapse of renal insufficiency closely paralleled the level of lymphocytosis. Kidney biopsy in all patients showed GIN concomitant with CLL/SLL leukemic interstitial infiltration. Granulomas were nonnecrotizing and epithelioid and were associated with giant cells. One biopsy showed granulomatous arteritis. One patient had a granulomatous reaction in lymph nodes and skin. Steroids with/without CLL/SLL-directed chemotherapy led to partial improvement of kidney function in all patients except 1 who had advanced cortical scarring on biopsy. In conclusion, we report an association between CLL/SLL and GIN. Patients typically present with severe renal failure due to both GIN and leukemic interstitial infiltration, which tends to respond to steroids with/without CLL/SLL-directed chemotherapy. The pathogenesis of GIN in this clinical setting is unknown but may represent a local hypersensitivity reaction to the CLL/SLL tumor cells. PMID:25795422

    2015-01-01

    Anti-allergic agents are used to treat a great variety of diseases which usually involve an inflammation reaction. These compounds act by inhibiting the release and the effects of inflammatory mediators (e.g. histamine) in the target tissue. The purpose of anti-allergy therapy is to deliver the drug to its local of action in a therapeutic concentration, minimizing the undesired side effects. In order to solve some of the anti-allergic agents' physicochemical drawbacks and the limitations associated to conventional pharmaceutical formulations (e.g. poor solubility and absorption, skin permeation, stability), novel drug delivery systems, such as cyclodextrins, liposomes, micelles, microemulsions, nano and microparticles, have been developed. Depending on the allergic condition, several administration routes are used to deliver anti-allergic agents, each with its own disadvantages to overcome. In the literature, there are a vast number of papers concerning novel delivery systems for anti-allergic agents, making it difficult to evaluate the information and the promising outcomes. The aim of the present review article is to compile the recent (i.e. in the new millennium) improvements of novel drug delivery technology focusing on the achievement of anti-allergic therapeutic delivery. The potential intrinsic benefits of these systems will reflect an increased therapeutic adherence and better patients' life quality. A critical prospect of future clinical trial directions will also be discussed. PMID:25895551

    Background and Objectives: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is the procedure of choice for the evaluation of mediastinal/hilar lymph node enlargements. Granulomatous inflammation of the mediastinal/hilar lymph nodes is often identified on routine histology. In addition, mediastinal lymphadenopathy may be present with undiagnosed infection. We sought to determine the usefulness of routine cultures and histology for infectious etiologies in a fungal endemic area when granulomatous inflammation is identified. Materials and Methods: We identified 56 of 210 patients with granulomatous inflammation on EBUS-TBNA biopsies from October 2012 through October 2014. An onsite cytologist evaluated all biopsies and an additional TBNA pass for microbiologic stains and cultures were obtained in those with granulomatous inflammation. Results: Of the 56 patients with granulomatous inflammation, 20 patients had caseating (necrotizing) granulomas while noncaseating (nonnecrotizing) granulomas were detected in 36 of the remainder patients. In patients with caseating granulomas, fungal elements were identified in 6 of 20 (30%) patients (histoplasma; N = 5, blastomyces; N = 1) on Grocott methenamine silver (GMS) stain. Lymph node cultures identified 3 of 20 (20%) patients as being positive for Mycobacterium tuberculosis (N = 1), Histoplasma capsulatum (N = 1), and Blastomyces dermatitidis (N = 1). Among patients with noncaseating granulomas, only 2 out of 36 (5%) were positive for fungal elements on GMS stain, identified as Histoplasma, although the lymph node cultures remained negative. Conclusion: The incidence of granulomatous inflammation of mediastinal lymph nodes was 26.6% in our series. Of these patients, noncaseating granulomas were more common (64% vs. 36%). Infectious organisms, fungal or acid-fast bacilli (AFB), on either staining or lymph node culture were rarely identified in noncaseating granulomas, 5% and none, respectively

    Pollen is the most common aeroallergen to cause seasonal conjunctivitis. The result of allergen exposure is a strong Th2-mediated response along with conjunctival mast cell degranulation and eosinophilic infiltration. Oleanolic acid (OA) is natural a triterpene that displays strong anti-inflammatory and immunomodulatory properties being an active anti-allergic molecule on hypersensitivity reaction models. However, its effect on inflammatory ocular disorders including conjunctivits, has not yet been addressed. Hence, using a Ragweed pollen (RWP)-specific allergic conjunctivitis (EAC) mouse model we study here whether OA could modify responses associated to allergic processes. We found that OA treatment restricted mast cell degranulation and infiltration of eosinophils in conjunctival tissue and decreased allergen-specific Igs levels in EAC mice. Th2-type cytokines, secreted phospholipase A2 type-IIA (sPLA2-IIA), and chemokines levels were also significantly diminished in the conjunctiva and serum of OA-treated EAC mice. Moreover, OA treatment also suppressed RWP-specific T-cell proliferation. In vitro studies, on relevant cells of the allergic process, revealed that OA reduced the proliferative and migratory response, as well as the synthesis of proinflammatory mediators on EoL-1 eosinophils and RBL-2H3 mast cells exposed to allergic and/or crucial inflammatory stimuli such as RWP, sPLA2-IIA or eotaxin. Taken together, these findings demonstrate the beneficial activity of OA in ocular allergic processes and may provide a new intervention strategy and potential therapy for allergic diseases.

    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.

    Allergic contact dermatitis resulting from exposure to a chemical or chemicals is a common diagnosis in the dermatologist's office. We are exposed to hundreds of potential allergens daily. Patch testing is the criterion standard for diagnosing the causative allergens responsible for allergic contact dermatitis. Patch testing beyond standard trays is often needed to fully diagnose patients, but not all dermatology practices have access to this testing procedure or these allergens. In order to adequately evaluate patients, physicians must understand the pathophysiology of the disease process and be well versed in the proper evaluation of patients, indications for patch testing, proper testing procedure, and other diagnostic tools available and be aware of new and emerging allergens.

    Lung nociceptors initiate cough and bronchoconstriction. To elucidate if these fibers also contribute to allergic airway inflammation, we stimulated lung nociceptors with capsaicin and observed increased neuropeptide release and immune cell infiltration. In contrast, ablating Nav1.8(+) sensory neurons or silencing them with QX-314, a charged sodium channel inhibitor that enters via large-pore ion channels to specifically block nociceptors, substantially reduced ovalbumin- or house-dust-mite-induced airway inflammation and bronchial hyperresponsiveness. We also discovered that IL-5, a cytokine produced by activated immune cells, acts directly on nociceptors to induce the release of vasoactive intestinal peptide (VIP). VIP then stimulates CD4(+) and resident innate lymphoid type 2 cells, creating an inflammatory signaling loop that promotes allergic inflammation. Our results indicate that nociceptors amplify pathological adaptive immune responses and that silencing these neurons with QX-314 interrupts this neuro-immune interplay, revealing a potential new therapeutic strategy for asthma.

    Afferent nerves, derived from the trigeminal ganglion, and postganglionic autonomic nerves, derived from sympathetic and parasympathetic ganglia expressing many different neurotransmitters, innervate the nose. Reflexes that serve to optimize the air-conditioning function of the nose by altering sinus blood flow, or serve to protect the nasal mucosal surface by mucus secretion, vasodilatation, and sneezing, can be initiated by a variety of stimuli, including allergen, cold air, and chemical irritation. Activation of nasal afferent nerves can also have profound effects on respiration, heart rate, blood pressure, and airway caliber (the diving response). Dysregulation of the nerves in the nose plays an integral role in the pathogenesis of allergic rhinitis. Axon reflexes can precipitate inflammatory responses in the nose, resulting in plasma extravasation and inflammatory cell recruitment, while allergic inflammation can produce neuronal hyper-responsiveness. Targeting the neuronal dysregulation in the nose may be beneficial in treating upper airway disease. PMID:11918862

    Although the concept of united airway disease has been widely accepted, most scholars emphasize only the effect of rhino-sinusitis while ignoring the pharyngeal factors to the lower airway, especially to the allergic pharyngitis (AP), which still lacks enough awareness. First of all, absence of unified diagnostic standard leads to the lack of epidemiological data, which, results in doctors' personal experience but no guideline in treatments. In addition, it is still not clear that the role of AP in the allergic airway diseases and its relationship with asthma. However, the number of patients with AP has been increasing obviously in daily clinic practice. Combined with the previous observation, this paper does a systematic review about the clinical problems of AP, expecting to give a hand to the clinical diagnosis and treatment of AP. PMID:26685417

    Asthma is a multifactorial disease in which the hereditary component has been demonstrated by familial and identical twin studies. Allergy is important in the aetiology of asthma and is characterized by a hyperreaction to allergens triggering predominantly the immunoglobulines E. The levels of these antibodies are found to be elevated even in non allergic asthmatics. The majority of genetic research in this area is focused on either the genes of the specific immune response or that of the non allergic response. These are the genes of the class II MHC, and the APY gene on chromosome 11q respectively. The modern techniques of molecular genetics and in particular those of inverse genetics have recently contributed to a more comprehensive understanding of this disease. PMID:8316547

  11. Mast Cells in Allergic Diseases and Mastocytosis

    Mast cells with their stores of vasoactive and chemotactic mediators are central to the pathogenesis of allergic diseases. The cross-linking of receptorbound IgE molecules on the surface of mast cells initiates a complex chain of events, including calcium ion influx, phospholipid methylation and turnover and cyclic nucleotide metabolism, ultimately resulting in the release of mediators of immediate hypersensitivity. These mast cell mediators are important in smooth muscle reactivity, in the recruitment of eosinophilic and neutrophilic leukocytes and in the generation of secondary chemical mediators. Histologic evidence of mast cell degranulation, biochemical evidence of mast cell mediators in blood and tissues and clinical evidence of signs and symptoms reproducible by these mediators have strongly supported the crucial role of mast cells in asthma, urticaria, anaphylaxis, rhinitis and mastocytosis. Because of their unique location at host environment interfaces, mast cells may both participate in allergic diseases and promote homeostasis. ImagesFigure 1.Figure 2.Figure 3. PMID:6293204

    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.

    Shirasaki, Hideaki; Himi, Tetsuo

    2016-01-01

    Cysteinyl leukotrienes (CysLTs) are lipid mediators that have been implicated in the pathogenesis of allergic rhinitis. Pharmacological studies using CysLTs indicate that two classes of receptor exist: CysLT1 receptor (CysLT1R) and CysLT2 receptor (CysLT2R). The CysLT1R is a high-affinity leukotriene D4 receptor with lower affinity for leukotriene C4 that is sensitive to the CysLT1R antagonist currently used to treat asthma and allergic rhinitis. Our previous immunohistochemical and autoradiographic studies have demonstrated the presence of anti-CysLT1R antibodies labeled in eosinophils, mast cells, macrophages, neutrophils and vascular endothelial cells in human nasal mucosa. Furthermore, we have revealed that the novel radioactive CysLT1R antagonist [3H]-pranlukast bound specifically to CysLT1R in human inferior turbinates and its binding sites were localized to vascular endothelium and the interstitial cells. These data suggest that the major targets of CysLT1R antagonists in allergic rhinitis are the vascular bed and infiltrated leukocytes such as mast cells, eosinophils and macrophages. Clinical trials have demonstrated that CysLT1R antagonists are as effective as antihistamines for the treatment of allergic rhinitis; however, they are less effective than intranasal steroids. The use of CysLT1R antagonists in combination with antihistamines has generally resulted in greater efficacy than when these agents were used alone. PMID:27115997

    High-conductive calcium-sensitive potassium channels (BK+Ca) and ATP-sensitive potassium (K+ATP) channels play a significant role in the airway smooth muscle cell and goblet cell function, and cytokine production. The present study evaluated the therapeutic potential of BK+Ca and K+ATP openers, NS 1619 and pinacidil, respectively, in an experimental model of allergic inflammation. Airway allergic inflammation was induced with ovalbumine in guinea pigs during 21 days, which was followed by a 14-day treatment with BK+Ca and K+ATP openers. The outcome measures were airway smooth muscle cells reactivity in vivo and in vitro, cilia beating frequency and the level of exhaled NO (ENO), and the level of pro-inflammatory cytokines in the plasma and bronchoalveolar lavage fluid. The openers of both channels decreased airway smooth muscle cells reactivity, cilia beating frequency, and cytokine levels in the serum. Furthermore, NS1619 reduced ENO and inflammatory cells infiltration. The findings confirmed the presence of beneficial effects of BK+Ca and K+ATP openers on airway defence mechanisms. Although both openers dampened pro-inflammatory cytokines and mast cells infiltration, an evident anti-inflammatory effect was provided only by NS1619. Therefore, we conclude that particularly BK+Ca channels represent a promising new drug target in treatment of airway's allergic inflammation. PMID:25315623

    The pathogenesis, epidemiology, presentation, diagnosis, and management of allergic rhinitis and asthma in the recreational and elite athlete are discussed in this study. There is an increased prevalence of allergic rhinitis and asthma in the elite athlete related to the enhanced ventilation with entrainment of inhalants including allergens as well as irritants such as pollutants in the urban athlete, chlorine in the swimmer, and cold air in the hockey player in the training environment. The history as well as objective exercise challenge and skin-prick tests to inhalants or in vitro allergen testing are essential in conjunction with a comprehensive physical exam to diagnosis of allergic rhinitis and/or asthma in the athlete. This is particularly necessary for the elite or competitive athlete who often has poor insight into the symptoms. Management is with appropriate inhaled steroids and/or leukotriene antagonists for the upper (nasal) and lower airways with avoidance of inhaled allergens and/or appropriate immunotherapy where relevant. The optimal management of the athlete results in minimum medication with minimum adverse side effects and optimal outcome. Proper adherence to antidoping regulations and application for use exemption in competitive athletes is recommended. The athlete should be encouraged to pursue the selected sports activity without limitations. PMID:16724626

    Respiratory allergies include allergic rhinitis, sinusitis and asthma. Increasing attention on pathogenesis of allergic airway diseases has given rise to "atopic march" hypothesis i.e. clinical features of atopic eczema occur first and precede the development of asthma and allergic rhinitis. The "hygiene hypothesis" proposes that the increase in allergic diseases reflects a decrease in infections during childhood. Clinical trials also suggest that the exposure to microbes through the gastrointestinal tract powerfully shapes immune function. Probiotics are live organisms which exert a beneficial effect in the prevention as well as treatment of allergic diseases through modification of immune system of host via gut ecosystem. Intestinal microbiota differs in infants who later develop allergic diseases, and feeding probiotics to infants at risk has been shown to reduce their rate of developing eczema. This has prompted studies of feeding probiotics in prevention as well as treatment of respiratory allergy. We hereby discuss the status of probiotics in respiratory allergy. PMID:19725896

    Background European legislators and wine producers still debate on the requirement for labeling of wines fined with potentially allergenic food proteins (casein, egg white or fish-derived isinglass). We investigated whether wines fined with known concentrations of these proteins have the potential to provoke clinical allergic reactions in relevant patients. Methods In-house wines were produced for the study, fined with different concentrations of casein (n = 7), egg albumin (n = 1) and isinglass (n = 3). ELISA and PCR kits specific for the respective proteins were used to identify the fining agents. Skin prick tests and basophil activation tests were performed in patients with confirmed IgE-mediated relevant food allergies (n = 24). A wine consumption questionnaire and detailed history on possible reactions to wine was obtained in a multinational cohort of milk, egg or fish allergic patients (n = 53) and patients allergic to irrelevant foods as controls (n = 13). Results Fining agents were not detectable in wines with the available laboratory methods. Nevertheless, positive skin prick test reactions and basophil activation to the relevant wines were observed in the majority of patients with allergy to milk, egg or fish, correlating with the concentration of the fining agent. Among patients consuming wine, reported reactions were few and mild and similar with the ones reported from the control group. Conclusion Casein, isinglass or egg, remaining in traces in wine after fining, present a very low risk for the respective food allergic consumers. Physician and patient awareness campaigns may be more suitable than generalized labeling to address this issue, as the latter may have negative impact on both non-allergic and allergic consumers.

    The prevalence of allergic respiratory diseases such as bronchial asthma has increased in recent years, especially in industrialized countries. A change in the genetic predisposition is an unlikely cause of the increase in allergic diseases because genetic changes in a population require several generations. Consequently, this increase may be explained by changes in environmental factors, including indoor and outdoor air pollution. Over the past two decades, there has been increasing interest in studies of air pollution and its effects on human health. Although the role played by outdoor pollutants in allergic sensitization of the airways has yet to be clarified, a body of evidence suggests that urbanization, with its high levels of vehicle emissions, and a westernized lifestyle are linked to the rising frequency of respiratory allergic diseases observed in most industrialized countries, and there is considerable evidence that asthmatic persons are at increased risk of developing asthma exacerbations with exposure to ozone, nitrogen dioxide, sulphur dioxide and inhalable particulate matter. However, it is not easy to evaluate the impact of air pollution on the timing of asthma exacerbations and on the prevalence of asthma in general. As concentrations of airborne allergens and air pollutants are frequently increased contemporaneously, an enhanced IgE-mediated response to aeroallergens and enhanced airway inflammation could account for the increasing frequency of allergic respiratory allergy and bronchial asthma. Pollinosis is frequently used to study the interrelationship between air pollution and respiratory allergy. Climatic factors (temperature, wind speed, humidity, thunderstorms, etc) can affect both components (biological and chemical) of this interaction. By attaching to the surface of pollen grains and of plant-derived particles of paucimicronic size, pollutants could modify not only the morphology of these antigen-carrying agents but also their allergenic

    PubMed

    Experimental mouse models of allergic asthma established almost 10 years ago offered new opportunities to study disease pathogenesis and to develop new therapeutics. These models focused on the factors governing the allergic immune response, on modeling clinical behavior of allergic asthma, and led to insights into pulmonary pathophysiology. Although mouse models rarely completely reproduce all the features of human disease, after sensitization and respiratory tract challenges with antigen, wild-type mice develop a clinical syndrome that closely resembles allergic asthma, characterized by eosinophilic lung inflammation, airway hyperresponsiveness (AHR), increased IgE, mucus hypersecretion, and eventually, airway remodeling. There are, however, differences between mouse and human physiology that threaten to limit the value of mouse models. Three examples of such differences relate to both clinical manifestations of disease and underlying pathogenesis. First, in contrast to patients who have increased methacholine-induced AHR even when they are symptom-free, mice exhibit only transient methacholine-induced AHR following allergen exposure. Second, chronic allergen exposure in patients leads to chronic allergic asthma, whereas repeated exposures in sensitized mice causes suppression of disease. Third, IgE and mast cells, in humans, mediate early- and late-phase allergic responses, though both are unnecessary for the generation of allergic asthma in mice. Taken together, these observations suggest that mouse models of allergic asthma are not exact replicas of human disease and thus, question the validity of these models. However, observations from mouse models of allergic asthma support many existing paradigms, although some novel discoveries in mice have yet to be verified in patients. This review presents an overview of the clinical aspects of disease in mouse models of allergic asthma emphasizing (1). the factors influencing the pathophysiological responses during

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.

    Chronic granulomatous disease (CGD) results from an inherited defect in the phagocytic cells of the immune system. It is a genetically heterogenous disease caused by defects in one of the five major subunits of the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex. There is a paucity of data from India on CGD. We herein describe the clinical features in 17 children with CGD from a single tertiary referral center in India. A detailed analysis of the clinical features, laboratory investigations and outcome of 17 children 7 with X-linked (XL) and 10 with autosomal recessive (AR) form was performed. Diagnosis of CGD was based on an abnormal granulocyte oxidative burst evaluated by either Nitroblue Tetrazolium (NBT) test or flow cytometry based Dihyrorhodamine 123 assay or both. The molecular diagnosis was confirmed by genetic mutation analysis in 13 cases. The mean age at diagnosis and the age at onset of symptoms was significantly lower in children diagnosed with XL- CGD compared those with AR disease. Mutations were detected in CYBB gene in 6 patients with XL-CGD and NCF-1 gene mutations were observed in 7 cases of AR- CGD. The course and outcome of the disease was much worse in children diagnosed with X-linked form of disease compared to AR forms of the disease; 4/7 (57%) children with X-CGD were dead at the time of data analysis. This is one of the largest series on chronic granulomatous disease from any developing country. PMID:24276928

Although liver abscess is a common manifestation of CGD, its management in CGD patients is not well-defined. In addition, the generalized guidelines for treating liver abscesses do not necessarily apply to CGD patients. Corticosteroids are commonly used to control granulomatous complications, such as inflammatory gastrointestinal and genitourinary lesions, in patients with CGD, Corticosteroids have also been used in combination with antimicrobials to treat refractory infections in patients with CGD. Because corticosteroids are capable of suppressing symptomatic inflammation, all potential infections must be adequately controlled prior to corticosteroid initiation. We report 3 typical CGD cases with liver abscesses refractory to conventional treatments that were successfully treated with the concomitant use of corticosteroid and antimicrobials. It remains unclear whether corticosteroid therapy is required for liver abscesses in CGD refractory to conventional treatments. However, based on our observations, use of corticosteroids in combination with optimal antimicrobials should be considered for refractory liver abscesses in CGD. PMID:27186231

We report 3 typical CGD cases with liver abscesses refractory to conventional treatments that were successfully treated with the concomitant use of corticosteroid and antimicrobials. It remains unclear whether corticosteroid therapy is required for liver abscesses in CGD refractory to conventional treatments. However, based on our observations, use of corticosteroids in combination with optimal antimicrobials should be considered for refractory liver abscesses in CGD. PMID:27186231

    A 77-year-old Japanese woman was transported to a nearby hospital due to sudden abdominal pain and transient loss of consciousness. Abdominal computed tomography (CT) suggested hemoperitoneum and hepatic nodule. She was conservatively treated. Contrast-enhanced CT two months later revealed an increased mass size, and the enhancement pattern suggested the possibility of hepatocellular carcinoma (HCC). Under a clinical diagnosis of HCC, transcatheter arterial chemoembolization (TACE) was performed. A subsequent imaging study revealed that most of the lipiodol used for the embolization was washed out. Therefore, surgical resection was performed. Histologically, the nodule contained numerous inflammatory cells including small lymphocytes, plasma cells and macrophages. Notably, epithelioid granulomatous features with multinucleated giant cells were observed in both the nodule and background liver. Some of the multinucleated giant cells contained oil lipid. Among the infiltrating inflammatory cells, spindle-shaped, histiocytoid or myoid tumor cells with eosinophilic cytoplasm were found. The tumor cells were positive for Melan A and HMB45. The nodule contained many IgG4-positive plasma cells; these were counted and found to number 72.6 cells/HPF (range: 61-80). The calculated IgG4:IgG ratio was 33.2%. The nodule was finally diagnosed as previously ruptured inflammatory angiomyolipoma modified by granulomatous reaction after TACE. PMID:26327777

    Granulomatous mastitis (GM) is a rare benign mammary lesion in which autoimmunity and hyperprolactinemia are considered possible etiological factors. GM has a high frequency of relapse and may lead to chronic ulceration and fistula if not treated properly. Here we report a case of a 22-year-old systemic lupus erythematosus (SLE) patient with three years' disease duration, stable on prednisone and hydroxychloroquine, who was found to have prolactinoma and recurrent GM after she discontinued medication on her own accord. The patient subsequently recovered and remained free of GM relapse under treatment of prednisone, hydroxychloroquine and bromocriptine. Though autoimmune disorders and prolactinoma were reported in GM, a coexisting condition of SLE, prolactinoma, and granulomatous mastitis has rarely been observed in one patient. We suggest our case as an illustrative example of the complex interaction between autoimmunity, neuroendocrine dysfunction, and manifestations in the breast: Immunological disturbances in the background of SLE, coupled with elevated prolactin levels secondary to a prolactinoma, may have predisposed the patient to the development of GM. The mammary lesion recovered and maintained free of relapse under immunosuppressive and antiprolactinemic therapy. PMID:24446305

    Cutaneous manifestations associated with myelodysplastic syndromes (MDS) are uncommon and can occur as specific or nonspecific lesions. Recognizing these cutaneous manifestations is important as they can precede blood or bone marrow transformation to leukemia. Granulomatous reactions have rarely been described as nonspecific lesions of MDS. These rare cases histologically resembled granuloma annulare, sarcoid, and a generalized dermal interstitial granulomatous dermatitis (IGD) which were not associated with leukemic infiltration. The authors report an interesting case of an IGD-like eruption evolving over the course of MDS with eventual progression to systemic leukemia. IGD is an inflammatory reaction that refers to a varied spectrum of histologic patterns and is associated with a variety of systemic illnesses and hypersensitivity reactions, including lymphoma and leukemia. In patients with MDS, surveillance for leukemia is a critical component of their follow-up care. Normally, this surveillance occurs through serial peripheral blood smears and bone marrow studies. IGD-like eruptions are a cutaneous reaction pattern that may serve as an additional clinical indicator of leukemic progression in patients with MDS. Although primarily a reactive pattern, this entity can rarely harbor leukemic blasts. PMID:23221468

    A 1.5-year-old female Mississippi sandhill crane (Grus canadensis pulla) was presented and managed for a polyarthritis of the intertarsal and tarsophalangeal articulations. Results of aerobic bacterial cultures, Mycoplasma species culture, and polymerase chain reaction testing of articular fluid did not identify any causative organisms. Results of radiographs and cytologic examination of articular fluid were consistent with an inflammatory, nonerosive polyarthritis. The arthritis did not improve with systemic anti-inflammatory and antibiotic treatment and with joint lavage. A large necrotic granulomatous mass was detected on the right shoulder area from which Staphylococcus aureus and Enterococcus species were isolated as opportunistic pathogens. Two days after surgical resection of the mass, the distal polyarthritis resolved. Histopathologic examination of the mass was consistent with granulomatous vasculitis with abscess formation of unknown origin. In this crane, the unresponsiveness to standard therapy, the presence of an infected and inflammatory mass, and the resolution of the polyarthritis after the resection of the mass strongly supported a diagnosis of reactive immune-mediated nonerosive polyarthritis. Analysis of this case suggests that immune-mediated idiopathic arthritis should be a differential diagnosis of distal polyarthritis in cranes and that an inciting source remote from the joints should be investigated in case of lack of response to standard therapy.

    Although polyethylene wear-induced osteolysis is a common complication of hip arthroplasty, extensile osteolysis developing into a large granulomatous thigh mass at a site distant from the joint is rare. We report a case of a thigh pseudotumor 25 years after cemented bipolar hemiarthroplasty, in which x-rays revealed a radiolucent line around the stem at the proximal site only, not at the diaphysis of the femur. We initially suspected a real tumor because it had a unique appearance, as if the mass resorbed the posterior cortex of the femur, and it was located at a site distant from the proximal osteolytic lesions. We clearly showed the existence of a connection between the thigh mass and the joint space by performing intra-articular injection of contrast medium with continuous pressure. It seemed that polyethylene wear particles were transported distally along the stem-cement interface by fluid pressure, and an osteolytic reaction against polyethylene wear particles had occurred at the posterior middle third of the stem where the cement mantle was nonuniform and polyethylene particles first came into contact with the bone. Our findings suggest that nonuniform cemented prosthesis with osteolysis, even if it is low grade in a limited area, carries the risk of extensile osteolysis with asymptomatic development of an extra-articular granulomatous mass.

    Prevalence of allergic rhinitis (AR) in elderly population in Turkey is not known. Studies on the prevalence and features of allergy in older adults are needed to identify safe and effective diagnostic/therapeutic methods for elderly AR patients. We aimed to identify the clinical and allergic characteristics of sensitization to aeroallergens among individuals aged ≥60 years with allergic rhinitis admitted to an allergy outpatient clinic in Istanbul. Of 109 patients, 33.9 % were atopic. Sixty-five percent of subjects were sensitized to Dermatophagoides pteronyssinus, 17 % to a grass-pollen mixture, 8 % to Aspergillus fumigatus, and 8 % to Blattella germanica. There was no difference between mono- and polysensitized patients in terms of the duration of rhinitis and symptom severity. No significant difference was observed between the two groups according to age, sex, smoking status, AR onset (<40 or ≥40 years), or duration/severity of disease. There was no significant difference between the two groups in the prevalence of asthma and conjunctivitis, (p = 0.256). Atopic dermatitis/eczema was more prevalent in those with AR (p = 0.046). Clinical characteristics of AR in the elderly could be different from those in non-allergic patients, and the prevalence of allergy may be higher than expected. PMID:25680346

    Several allergen-specific plasma proteins, such as IgE and IgG subclasses, are commonly used for the evaluation of grade of allergy. In the present investigation, we compared the concentration of various nonspecific plasma proteins, mostly known as inflammation markers, in an allergic and a healthy population. Plasma from 130 children with single inhalation allergies to grass pollen, birch pollen, or house dust mites as well as from 42 healthy children was obtained during the symptom-free period. Patients showed symptoms including allergic rhinitis, dermatitis, and asthma with one single radioallergosorbent test (RAST) class 3 or higher. Plasma concentrations of soluble intercellular adhesion molecule-1(sICAM-1), soluble interleukin-2 receptor(sIL-2R), sE-selectin, and soluble vascular cell adhesion molecule-1 (1sVCAM-1) were analyzed by enzyme linked immunosorbent assay (ELISA) technique. Concentrations of sICAM-1 and sE-selectin were significantly increased in all patients compared to controls. In the single allergen groups, sICAM-1 elevation was significant in the grass and mite groups, but not in the birch group; while sE-selection increase was significant in the birch and mite groups, but not in the grass group. The elevation of sIL-2R in the allergic patients was obvious in each single allergen group, but not significant. No difference was observed in sVCAM-1 expression. In two groups of patients with mean age of 9.5 years versus 17.5 years, the analyzed parameters were not age dependent. The increased proteins may be useful as additional markers for efficacy and follow-up investigations of allergy therapies. PMID:12861853

    In susceptible individuals, inhalation of Aspergillus spores can affect the respiratory tract in many ways. These spores get trapped in the viscid sputum of asthmatic subjects which triggers a cascade of inflammatory reactions that can result in Aspergillus-induced asthma, allergic bronchopulmonary aspergillosis (ABPA), and allergic Aspergillus sinusitis (AAS). An immunologically mediated disease, ABPA, occurs predominantly in patients with asthma and cystic fibrosis (CF). A set of criteria, which is still evolving, is required for diagnosis. Imaging plays a compelling role in the diagnosis and monitoring of the disease. Demonstration of central bronchiectasis with normal tapering bronchi is still considered pathognomonic in patients without CF. Elevated serum IgE levels and Aspergillus-specific IgE and/or IgG are also vital for the diagnosis. Mucoid impaction occurring in the paranasal sinuses results in AAS, which also requires a set of diagnostic criteria. Demonstration of fungal elements in sinus material is the hallmark of AAS. In spite of similar histopathologic features, co-existence of ABPA and AAS is still uncommon. Oral corticosteroids continue to be the mainstay of management of allergic aspergillosis. Antifungal agents play an adjunctive role in ABPA as they help reduce the fungal load. Saprophytic colonization in cavitary ABPA may lead to aspergilloma formation, which could increase the severity of the disease. The presence of ABPA, AAS, and aspergilloma in the same patient has also been documented. All patients with Aspergillus-sensitized asthma must be screened for ABPA, and AAS should always be looked for. PMID:27126721

    Objectives The internet has become an important source of medical information and a great amount of information related to allergic rhinitis (AR) is available on the internet. However, the quality of this information is still a matter of debate. Therefore, this study was conducted to assess the AR-related information on Korean websites. Methods The key word "allergic rhinitis" was entered into 4 popular search engines, and this led to identifying 40 websites. After being categorized according to authorship, the informational value of these websites was evaluated using 4 different assessment tools such as the Journal of the American Medical Association (JAMA) benchmarks, the DISCERN questionnaire, the Allergic Rhinitis and its Impact on Asthma (ARIA) 2008 Update and the Health On the Net (HON) code. Results The 40 websites containing AR-related information were categorized according to their authorship as Western physician: 20, Oriental physician: 14, commercial: 1, and others: 5. The mean citation frequencies of the JAMA benchmarks and the ARIA 2008 Update concepts was 1.23 out of 4 and 4.33 out of 8, respectively, while the mean DISCERN score was 1.92 out of 5. When the websites were evaluated based on the type of authorship, the mean citation frequencies of the ARIA 2008 Update concepts were Western physician: 5.35, Oriental physician: 2.64. Additionally, three websites authored by Western physicians and 13 authored by Oriental physicians contained unreliable information. Among these 16 websites, only 3 websites met the requirements for the HON code "Justification". Conclusion AR-related information available on Korean websites is of variable quality and not all of the information provided is justifiable. Thus, performing surveillance of the medical information on these websites is necessary. Furthermore, common criteria that can be used to evaluate the websites created by both Western and Oriental physicians are also needed. PMID:20379400

    Allergic contact dermatitis is a common diagnosis resulting from exposure to a chemical or chemicals in a patient's personal care products, home, or work environment. Once patch testing has been performed, the education and management process begins. After the causative allergens have been identified, patient education is critical to the proper treatment and management of the patient. This must occur if the dermatitis is to resolve. Detailed education is imperative, and several resources are highlighted. Photoallergic contact dermatitis and occupational contact dermatitis are other considerations a clinician must keep in mind.

    Ornamental plants (OPs) can lead to immediate-type sensitization and even asthma and rhinitis symptoms in some cases. This study aimed to evaluate sensitization to OPs in patients with asthma and/or allergic rhinitis and to determine the factors affecting the rate of sensitization to OPs. A total of 150 patients with asthma and/or allergic rhinitis and 20 healthy controls were enrolled in the study. Demographics and disease characteristics were recorded. Skin-prick tests were performed with a standardized inhalant allergen panel. Skin tests by "prick-to-prick" method with the leaves of 15 Ops, which are known to lead to allergenic sensitization, were performed. Skin tests with OPs were positive in 80 patients (47.1%). There was no significant difference between OP sensitized and nonsensitized patients in terms of gender, age, number of exposed OPs, and duration of exposure. Skin test positivity rate for OPs was significantly high in atopic subjects, patients with allergic rhinitis, food sensitivity, and indoor OP exposure, but not in patients with pollen and latex allergy. Most sensitizing OPs were Yucca elephantipes (52.5%), Dieffenbachia picta (50.8%), and Euphorbia pulcherrima (47.5%). There was significant correlation between having Saintpaulia ionantha, Croton, Pelargonium, Y. elephantipes, and positive skin test to these plants. Sensitivity to OPs was significantly higher in atopic subjects and patients with allergic rhinitis, food allergy, and indoor OP exposure. Furthermore, atopy and food sensitivity were found as risk factors for developing sensitization to indoor plants. Additional trials on the relationship between sensitization to OPs and allergic symptoms are needed. PMID:24717779

    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

    The aim of current study is to describe clinical similarities and differences between atopic and non-atopic asthma in children. In a cross-sectional study, 95 asthmatic children (75 allergics and 20 nonallergics) were included in the study. Demographic, clinical, and familial history were compared between two groups. There was no significant differences between variables like sex, age of onset (p=0.75), severity (p=0.70), and family history among the two groups (p=0.42). Patients with allergic asthma were significantly older than those with non- allergic asthma (11.28 ± 3.19 and 9.75 ± 2.35 years, respectively, p=0.02). The controversy lingers over the presence of a completely distinct phenotype of non-atopic asthma in children. Our study suggested that phenotypes of allergic and non-allergic asthma in children were not entirely distinct. PMID:25150079

    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.

    One of the severe toxicities of pegaspargase (PEG) is the development of allergic reactions. This study retrospectively assessed 311 PEG doses administered to 139 acute lymphoblastic leukemia patients from May 1, 2008 to July 30, 2014 for allergic reactions based on the Common Terminology Criteria for Adverse Events (CTCAE) version 4.03. Fourteen reactions were recorded in 13 patients (9.4%). The rate of reaction did not differ between patients who received pre-medications and those who did not (p = 0.939). Patients who received only IV PEG doses had a higher rate of reaction compared to only IM PEG (14.0% vs 1.6%; p = 0.010). Six of the seven patients with CTCAE grade 4 reactions received a majority of IV doses, suggesting that severity of reactions may increase with IV administration. Capped doses at 3750 units only had a reaction rate of 2.3%, while uncapped doses over 3750 units were found to have a 6.0% reaction rate (p = 0.194). PMID:26461960

    Purpose of review This review highlights recent findings regarding the immune regulation of allergic conjunctivitis (AC). Mouse models have facilitated prospective studies that have not been possible in patients. The availability of gene knockout mice and the wealth of monoclonal antibodies have permitted exquisite dissection of the pathophysiology and immune regulation of AC. Recent findings New insights have emerged in three areas: a) role of costimulatory molecules in the induction of Th2 immune responses; b) crucial role of interferon-γ (IFN-γ) in the expression of AC; and c) the function of T regulatory cells in shaping conjunctival inflammation once the immune response has been initiated. Summary Allergic conjunctivitis involves early phase and late phase reactions. The early phase reaction (EPR) is IgE antibody-dependent, while the late phase reaction (LPR) is IgE-independent and is mediated by inflammatory cells, especially eosinophils. Recent studies in mouse models of AC have provided important insights into the immune regulation of both the EPR and LPR of AC. Mounting evidence suggests that IFN-γ is crucial for optimum expression of AC. Costimulatory molecules influence the induction of Th2 immune responses and the EPR while regulatory T cells shape the expression of the LPR of AC. PMID:18769204

    2014-01-01

    Allergic sensitization is a multifactorial process that is not only influenced by the allergen and its biological function per se but also by other small molecular compounds, such as lipids, that are directly bound as ligands by the allergen or are present in the allergen source. Several members of major allergen families bind lipid ligands through hydrophobic cavities or electrostatic or hydrophobic interactions. These allergens include certain seed storage proteins, Bet v 1–like and nonspecific lipid transfer proteins from pollens and fruits, certain inhalant allergens from house dust mites and cockroaches, and lipocalins. Lipids from the pollen coat and furry animals and the so-called pollen-associated lipid mediators are codelivered with the allergens and can modulate the immune responses of predisposed subjects by interacting with the innate immune system and invariant natural killer T cells. In addition, lipids originating from bacterial members of the pollen microbiome contribute to the outcome of the sensitization process. Dietary lipids act as adjuvants and might skew the immune response toward a TH2-dominated phenotype. In addition, the association with lipids protects food allergens from gastrointestinal degradation and facilitates their uptake by intestinal cells. These findings will have a major influence on how allergic sensitization will be viewed and studied in the future. PMID:24880633

    Atopic disorders are a major global health problem. The prevalence of asthma, allergic rhinitis and atopic dermatitis has been increasing over the last four decades, both in the industrialized and developing countries. It seems to be related to changes in the social structure, increasing industrialization, pollution and dietary changes. Many hypotheses link the allergy epidemic to stringent hygiene, dominance of a westernized lifestyle and an accelerated pace of life. Dietary antioxidants, lipids, sodium, vitamin D seem also to be implicated. We endeavour to review the most relevant theories with a special emphasis on the hygiene, antioxidative, lipid and air pollution hypotheses. It is however important to note that none of them explains all the aspects of unprecedented rise in the prevalence of allergic disorders. A complex interplay between host's immune response, invading pathogens, diversity of environmental factors and genetic background seems to be of a particular importance. Current allergy epidemic is multifactorial and basic and epidemiologic studies are warranted to further our understanding of this phenomenon. PMID:25097472

    New allergic diseases can “emerge” because of exposure to a novel antigen, because the immune responsiveness of the subject changes, or because of a change in the behavior of the population. Novel antigens have entered the environment as new pests in the home (e.g., Asian lady beetle or stink bugs), in the diet (e.g., prebiotics or wheat isolates), or because of the spread of a biting arthropod (e.g., ticks). Over the last few years, a significant new disease has been identified, which has changed the paradigm for food allergy. Bites of the tick, Amblyomma americanum, are capable of inducing IgE antibodies to galactose-alpha-1,3-galactose, which is associated with two novel forms of anaphylaxis. In a large area of the southeastern United States, the disease of delayed anaphylaxis to mammalian meat is now common. This disease challenges many previous rules about food allergy and provides a striking model of an emerging allergic disease. PMID:24095162

    An 86-year-old man, diagnosed as having mycosis fungoides in May 2008 and treated with repeated radiation therapy, was admitted to our hospital for initiation of hemodialysis due to end-stage renal disease (ESRD) in April 2012. On admission, his corrected serum calcium level was 9.3 mg/dL, and his intact parathyroid hormone level was 121.9 pg/mL (normal range 13.9-78.5 pg/mL), indicating secondary hyperparathyroidism due to ESRD. After starting hemodialysis, urinary volume diminished rapidly. The serum calcium level increased (12.7 mg/dL), and the intact parathyroid hormone level was suppressed (< 5 pg/mL), while the 1,25-dihydroxyvitamin D3 (calcitriol) level increased (114 pg/mL, normal range: 20.0-60.0 pg/mL) in June 2012. The possibilities of sarcoidosis and tuberculosis were ruled out. Skin biopsies from tumorous lesions revealed a diagnosis of granulomatous mycosis fungoides. The serum soluble interleukin-2 receptor levels and the degrees of skin lesions went in parallel with the increased serum calcium and calcitriol levels. Therefore, the patient was diagnosed as having calcitriol-induced hypercalcemia possibly associated with granulomatous mycosis fungoides. Granulomatous mycosis fungoides is rare, and its association with calcitriol-induced hypercalcemia has not been reported. Careful attention to calcium metabolism is needed in patients with granulomatous mycosis fungoides, especially in patients with ESRD. PMID:24175265

    Aim The aim of this study is to characterise the choroidal features of patients diagnosed with sarcoid- and tuberculosis (TB)-associated granulomatous uveitis using spectral domain optical coherence tomography (OCT). 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 chronic benign inflammatory disease of the breast with unknown etiology. It is an important diagnostic and therapeutic challenge, as most patients were initially misdiagnosed by their primary care physicians, leading to diagnostic confusion and heightened anxiety. Although several triggers have been proposed for development of IGM, the etiologic association of neither of them has been documented. Three main hypotheses about the possible causes of IGM have been suggested, including autoimmune response, infectious disease, and hormonal disruption. Here, we discuss a hypothetical perspective of IGM to explain the possible role of autoinflammation in the pathogenesis of the disease. We also reviewed the previously published literature on pathogenesis of IGM. PMID:26829298

    Common variable immune deficiency (CVID) and chronic granulomatous disease (CGD) are two of the well-characterized primary immune deficiencies with distinct pathologic defects. While CVID is predominantly a disorder of the adaptive immune system, in CGD, innate immunity is impaired. In both syndromes, the clinical manifestations include an increased susceptibility to infections and a number of non-infectious, inflammatory conditions including systemic autoimmunity, as well as organ-specific pathology. Among the organ-associated disorders, gastrointestinal (GI) manifestations are one of the most intractable. As such, non-infectious inflammatory disorders of the GI tract are clinically challenging as they have protean manifestations, often resembling inflammatory bowel disease (IBD) or celiac disease, are notoriously difficult to treat, and hence are associated with significant morbidity and mortality. Therefore, assessing the pathogenesis and defining appropriate therapeutic approaches for GI disease in patients with CVID and CGD is imperative. PMID:26951230

    Hematopoietic cell transplantation (HCT) is the only available curative therapy for chronic granulomatous disease (CGD), but its use is limited by transplant-related mortality (TRM) in patients who often come to transplant with existing infections or organ dysfunction. Reduction in the intensity of the preparative regimen mitigates these risks, but increases the potential for mixed donor-recipient chimerism (MC) that may progress to graft loss. Recently a busulfan-based reduced-intensity conditioning (RIC) regimen has been described with excellent survival and little MC. We report our experience with a similar RIC regimen at our institution, demonstrating problems with donor chimerism and graft loss. Pediatr Blood Cancer © 2014 Wiley Periodicals, Inc. PMID:25175046

    We present a case of nonspecific granulomatous prostatitis (GP), a clinical mimic of prostate adenocarcinoma. A 54-year-old man presented with lower urinary tract symptoms and raised prostate-specific antigen. Magnetic resonance imaging showed features consistent with prostate cancer, including low T2-signal intensity in the peripheral and transition zones with signs of extracapsular extension. Diffusion-weighted imaging showed high-signal intensity, with low apparent diffusion coefficient values, whereas dynamic contrast enhancement demonstrated a type 3 washout curve, similar to that found in prostate cancer. Transperineal sector-guided prostate biopsy confirmed nonspecific GP, and the patient was treated conservatively. We discuss and compare nonspecific, chronic GP as a radiologic mimic of prostate adenocarcinoma patient. PMID:27257455

    Chronic granulomatous disease (CGD) is a rare inherited condition rendering neutrophils incapable of killing invading pathogens. This condition is due to the failure of a multicomponent microbicidal oxidase that normally yields a low-midpoint-potential b cytochrome (cytochrome b{sub 245}). Although defects in the X chromosome-linked cytochrome account for the majority of CGD patients, as many as 30% of CGD cases are due to an autosomal recessive disease. Of these, {gt}90% have been shown to be defective in the synthesis of a 47-kDa cytosolic component of the oxidase. The authors demonstrate here in three unrelated cases of autosomal recessive CGD that the identical underlying molecular lesion is a dinucleotide deletion at a GTGT tandem repeat, corresponding to the acceptor site of the first intron - exon junction. Slippage of the DNA duplex at this site may contribute to the high frequency of defects in this gene.

    A 61-year-old woman presented with longstanding cough and progressive dyspnoea. She underwent an extensive evaluation and was diagnosed with common variable immunodeficiency (CVID) with granulomatous lymphocytic interstitial lung disease (GLILD). She was initially treated with subcutaneous immunoglobulin therapy, having declined intravenous immunoglobulin (IVIG) therapy. She also declined treatment with oral glucocorticoids. Over several months, she became increasingly symptomatic and developed increased pulmonary infiltrates, pleural effusions, mediastinal adenopathy, splenomegaly, pancytopenia and ascites. An interdisciplinary team composed of an immunologist, pulmonologist and haematologist deliberated over a therapeutic management approach. The patient received a recently reported immunotherapy regimen with azathioprine and rituximab. The therapy led to rapid improvement of her constitutional and respiratory symptoms, with clinical and radiographic improvement in her interstitial lung disease, lymphadenopathy, pleural effusions and ascites. This case report reviews the literature surrounding the diagnosis and management of GLILD. PMID:27335365

    A 34-year-old immunocompetent man weighing 95 kg was operated for a small left parietal scalp swelling in the year 2002. He was well until 2008, when he developed chronic diffuse headache, vomiting and drowsiness. The left parietal dura and overlying vault biopsy showed evidence of granulomatous pachymeningitis with osteomyelitis secondary to nocardiosis. He had responded well to inadequate antibiotic therapy. After a dormant period of 3 years, there was recrudescence of severe raised intracranial tension symptoms in 2011. Magnetic resonance imaging showed diffuse pachymeningeal thickening mainly involving the occipital dura, posterior falx, and tentorium cerebelli. In addition, well-defined small nodules with hypointense signals on both T1- and T2-weighted images were seen in occipital lobes. Patient was treated with three drug regime with good recovery at 3 months follow-up. This is a rare case of central nervous system nocardiosis with skull vault osteomyelitis and a protracted clinical course. PMID:24943782

    This report describes 2 genetically related paint mares, case Nos. 1 and 2, presented to the Oklahoma State University Boren Veterinary Medical Teaching Hospital for chronic weight loss and abnormal gait, respectively. Notable findings in both cases included marked persistent eosinophilia and multiple intramuscular lateral thoracic masses. Histologic examination of masses revealed eosinophilic, centrally necrotic granulomas and marked eosinophilic myositis. Granulomas in case No. 1 also contained intralesional Sarcocystis sp material, and adjacent muscle fibers contained intact protozoal cysts. Case No. 1 developed severe refractory muscle pain and recurrent esophageal dysphagia. At necropsy, disseminated, grossly visible granulomas were present throughout all examined striated muscles. Nested polymerase chain reaction of the 18S rRNA gene revealed >99% homology with Sarcocystis fayeri. Sarcocystis spp are apicomplexan protozoa that infect striated muscle of many omnivorous species, typically without inciting clinical disease. Sarcocystosis should be considered a rare cause of granulomatous eosinophilic myositis and choke in horses. PMID:25957356

    Chronic granulomatous disease (CGD) is a disorder of phagocytes that is usually inherited as an X chromosome-linked trait. Previous family studies suggested that the CGD locus resides on the distal short arm (Xp22-Xpter). Using cloned, polymorphic DNA probes we have performed a linkage analysis within CGD families that suggests a more proximal location (Xp21). In addition, the CGD locus is proximal to the Duchenne muscular dystrophy locus and lies within a broad region of Xp in which recombination appears to be greater than anticipated on the basis of physical distance between markers. Regional localization of the X chromosome CGD locus should facilitate molecular cloning of the CGD gene and molecular dissection of the phagocyte oxidase system. Images PMID:3010296

    Chronic granulomatous disease (CGD), a primary immunodeficiency caused by impaired phagocyte killing of intracellular pathogens, is characterized by recurrent, life-threatening, bacterial and fungal infections. As a result of improvements in microbiologic culture and identification techniques, a number of unique filamentous fungi have been reported as significant pathogens in patients with CGD. We report a case of subcutaneous basidiomycete Phellinus mori infection in a patient with CGD. To the best of our knowledge, this is the first reported case of human infection by this fungus. The causative fungus was identified on the basis of its morphological characteristics and nucleotide sequence on the internal transcribed spacer region of the ribosomal RNA gene. This is the fifth case report of filamentous basidiomycetes infecting a patient with CGD; all of these cases have been caused by Phellinus species. We highlight the importance of recognizing filamentous basidiomycetes Phellinus species as possible agents of non-Aspergillus fungal infections in patients with CGD. PMID:25600930

    Malignant melanoma is the most aggressive cutaneous malignancy with dismal prognosis in the advanced setting. The food and drug administration approval of ipilimumab, the monoclonal antibody against cytotoxic T-lymphocyte antigen 4, has significantly changed treatment strategies for this disease. However, the spectrum of immune-related adverse events secondary to ipilimumab therapy is a growing area of research, and clinical observations of rare immune events as a result of such therapies continue to be reported since the approval. The co-occurrence of disease progression along with an immune-related adverse event is extremely rare. We here present the first case, to our knowledge, of diffuse nonnecrotizing granulomatous lymphadenopathy occurring simultaneously with disease progression in a patient with metastatic melanoma after receiving the second dose of ipilimumab.

    Interstitial granulomatous dermatitis (IGD), a rare disease, is well known to be associated with connective tissue disorders, malignancies and several drugs. We describe this first case of IGD in association with chronic lymphocytic leukaemia/small lymphocytic lymphoma (CLL/SLL). A 66-year-old woman with a 6-year history of untreated CLL/SLL, presented with a 2-month history of progressively worsening eruption of the left thigh, along with fatigue, lymphadenopathy and night sweats. Skin biopsy showed findings consistent with IGD and infiltration of CLL. The eruption was non-responsive to treatment with antibiotics and local steroids. There was a significant improvement in the rash after an initial cycle of chemotherapy (combination therapy with bendamustine and rituximab) and complete resolution by the third cycle, for the treatment of her CLL. We suggest that the possibility of an underlying haematological malignancy should be investigated in patients with a skin rash non-responsive to conventional therapy. PMID:27194675

    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

    Mycobacterium bovis is the causative agent of bovine tuberculosis. The diagnostic laboratory confirmation is made through bacterial isolation. The aim of interlaboratory tests is to assess the performance of each participant in comparison with other of similar capacities. The test objective was to determine the efficiency of isolation of M. bovis. Four laboratories were part of the test and processed 25 blind tissue samples from granulomatous lesions and with previous M. bovis isolation. The laboratory that had the highest proportion of isolates was A (68%), followed by C (60%) and then B and D (both with 52%). The greatest concordance was observed between B-D and B-C laboratories (68%). The differences could be due to specific factors in each laboratory procedures. This type of interlaboratory tests highlights errors in the bacteriology and identifies critical points in the process to detect M. bovis accurately. PMID:27237425

    The presence of Tropheryma whippelii was demonstrated in the PAS-negative mesenteric granulomatous lymph nodes of a patient affected by Whipple disease. Ultrastructurally a few bacteria, enclosed by a membrane characteristic of Tropheryma whippelii, were found in the extracellular spaces and remnants of bacteria were found in the phagocytic vacuoles of macrophages. The scarce number of bacilli, probably due to the fact that the disease was at an initial phase, could explain the absence of PAS positivity. This case confirms the role of the electron microscopy in the diagnosis of Whipple disease, especially for extra-intestinal lesions and at the initial phase of the disease, when the characteristic PAS-positive macrophages can be absent.

    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

    Perennial and seasonal allergic rhinitis affect many million Americans and account for close to $2 billion annually in medical costs and lost productivity. The symptoms of allergic rhinitis, including sneezing, rhinorrhea, nasal congestion, and pruritus are, at best, very annoying and may be quite debilitating in some patients, causing irritability, insomnia, and fatigue. Moreover, allergic rhinitis is often not self-limiting and can contribute to serious medical complications such as sinusitis and otitis. Aggressive medical management of allergic rhinitis is important in the therapy for chronic sinusitis and otitis media and may prevent progression to more serious disease. Accurate diagnosis and initiation of environmental control measures to reduce exposure to causative factors should accompany initiation of pharmacotherapy. Antihistamines form the cornerstone of pharmacologic therapy, and use of the newer nonsedating antihistamines such as loratadine, terfenadine, and astemizole is not associated with the sedation produced by the classic antihistamines. Both loratadine and terfenadine are available in combination with a decongestant. Topical intranasal corticosteroids are another important component of pharmacologic management of allergic rhinitis. Allergen immunotherapy (hyposensitization) is used in those patients not adequately managed with pharmacotherapy. The relative safety and convenient dosing schedule of the newer medications should be accompanied by enhanced patient compliance and, hence, better control of allergic symptoms, halting progression of allergic rhinitis to serious medical complications.

    The present study aimed to describe and characterize the cellular components during the evolution of chronic granulomatous inflammation in the teleost fish pacus (P. mesopotamicus) induced by Bacillus Calmette-Guerin (BCG), using S-100, iNOS and cytokeratin antibodies. 50 fish (120±5.0 g) were anesthetized and 45 inoculated with 20 μL (40 mg/mL) (2.0 x 106 CFU/mg) and five inoculated with saline (0,65%) into muscle tissue in the laterodorsal region. To evaluate the inflammatory process, nine fish inoculated with BCG and one control were sampled in five periods: 3rd, 7th, 14th, 21st and 33rd days post-inoculation (DPI). Immunohistochemical examination showed that the marking with anti-S-100 protein and anti-iNOS antibodies was weak, with a diffuse pattern, between the third and seventh DPI. From the 14th to the 33rd day, the marking became stronger and marked the cytoplasm of the macrophages. Positivity for cytokeratin was initially observed in the 14th DPI, and the stronger immunostaining in the 33rd day, period in which the epithelioid cells were more evident and the granuloma was fully formed. Also after the 14th day, a certain degree of cellular organization was observed, due to the arrangement of the macrophages around the inoculated material, with little evidence of edema. The arrangement of the macrophages around the inoculum, the fibroblasts, the lymphocytes and, in most cases, the presence of melanomacrophages formed the granuloma and kept the inoculum isolated in the 33rd DPI. The present study suggested that the granulomatous experimental model using teleost fish P. mesopotamicus presented a similar response to those observed in mammals, confirming its importance for studies of chronic inflammatory reaction.

    Introduction Idiopathic granulomatous mastitis (IGM) is becoming more commonly recognized and reported more often. Currently, many recommend corticosteroids in its management. Presentation of case A 34-year-old G3P2 Hispanic female, 28 weeks pregnant, presented with a 19 cm right breast mass. She had a known prolactinoma treated with bromocriptine which was discontinued during her pregnancy. Ultrasound guided core biopsy procedure revealed granulomatous mastitis. The patient was told that the mass would resolve with observation. The patient seen at another institution by an infectious disease specialist who started treatment with amphotericin for presumptive disseminated coccidioidomycosis. Repeated titers were negative for coccidioides antibody. Repeat cultures were negative as well. Due to the persistence of the infectious disease specialist, tissue cultures were performed on fresh tissue specimens, which did not grow bacterial, fungal, nor acid fast organisms. The amphotericin regimen resulted in no improvement of her breast mass after 10 weeks. Within two weeks of stopping the antifungal therapy, however, the mass diminished to 6 cm. The patient delivered at 39 weeks. Bromocriptine was restarted, and within 4 weeks, the lesion was no longer palpable. She had not shown signs of recurrence for 32 months. Discussion Treatment recommendations for IGM vary widely but antibiotics and antifungal medications are not recommended. Corticosteroid treatment is most commonly recommended, however, outcomes may not be different from management with observation. Prolactin may be involved in the pathophysiology of the process. Conclusion IGM is becoming recognized more frequently. Observation and patience with natural history can be an effective management. PMID:25781920

    Sarcoidosis, a chronic granulomatous disease of unknown cause, has been linked to several environmental risk factors, among which are some that may favor carbon nanotube formation. Using gene array data, we initially observed that bronchoalveolar lavage (BAL) cells from sarcoidosis patients displayed elevated mRNA of the transcription factor, Twist1, among many M1-associated genes compared to healthy controls. Based on this observation we hypothesized that Twist1 mRNA and protein expression might become elevated in alveolar macrophages from animals bearing granulomas induced by carbon nanotube instillation. To address this hypothesis, wild-type and macrophage-specific peroxisome proliferator-activated receptor gamma (PPARγ) knock out mice were given oropharyngeal instillation of multiwall carbon nanotubes (MWCNT). BAL cells obtained 60 days later exhibited significantly elevated Twist1 mRNA expression in granuloma-bearing wild-type or PPARγ knock out alveolar macrophages compared to sham controls. Overall, Twist1 expression levels in PPARγ knock out mice were higher than those of wild-type. Concurrently, BAL cells obtained from sarcoidosis patients and healthy controls validated gene array data: qPCR and protein analysis showed significantly elevated Twist1 in sarcoidosis compared to healthy controls. In vitro studies of alveolar macrophages from healthy controls indicated that Twist1 was inducible by classical (M1) macrophage activation stimuli (LPS, TNFα) but not by IL-4, an inducer of alternative (M2) macrophage activation. Findings suggest that Twist1 represents a PPARγ-sensitive alveolar macrophage M1 biomarker which is induced by inflammatory granulomatous disease in the MWCNT model and in human sarcoidosis.

    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. PMID:17418949

    Background: Xanthii Fructus (XF) is widely used in traditional anti-bacterial and anti-inflammatory Asian medicine. Allergic rhinitis is a common inflammatory disease characterized by markedly increased levels of anti-inflammatory factors and the recruitment of inflammatory cells into the nasal mucosa. We investigated the effects of XF in the allergen-induced rhinitis model. Materials and Methods: Following ovalbumin (OVA)/alum intraperitoneal injection on days 0, 7 and 14, the BALB/c mice (albino, laboratory-bred strain of the house mice) were challenged intranasally with OVA for 10 days a week after the last sensitization. The number of sneezes was recorded for 10 days; additionally, the levels of cytokines, histamine, immunoglobulin E (IgE) and OVA-specific serum IgE were estimated. Eosinophil infiltration, thickness of nasal mucosa and expression of caspase-1 were determined by immunohistochemistry. We also evaluated the effect of XF on the phosphorylation of nuclear factor kappa-B (NF-κB) and inhibitor of nuclear factor kappa B-alpha (IκB-α) in human mast cell-1 (HMC-1), by Western blotting. Results: The administration of XF significantly decreased sneezing and the serum levels of histamine, IgE, OVA-specific IgE, and cytokines such as tumor necrosis factor-alpha (TNF-α), interleukine-1 beta (IL-1β), IL-5, IL-6, monocyte chemoattractant protein-1 (MCP-1) and macrophage inflammatory protein-2 (MIP-2). XF inhibited the changes in thickness of the nasal septum, influx of eosinophils and expression of capase-1. In addition, XF inhibited the phosphorylation of IκB-α and NF-κB in phorbol-myristate-acetate plus calcium ionophore A23187 (A23187) stimulated HMC-1. Conclusion: This study suggests that XF acts a potent anti-allergic drug which alleviates the allergic responses in ovalbumin-sensitized mouse allergic rhinitis model. PMID:26664025

    Two experiments were performed during the pollen season to study the activity of different antiallergic drugs in the treatment of seasonal allergic rhinitis. Nasal allergen challenge (NAC) was performed to mimic an acute attack of allergic rhinitis and to objectively evaluate the effect of the drugs on the early-phase reaction during the season. The first study assessed the effect of H1 (Cetirizine 10 mg a day) and of a combination of H1 (Cetirizine 10 mg) plus H2 (Cimetidine 800 mg a day) antagonists on nasal symptoms, mediator release and eosinophil count in a group of 16 patients with seasonal allergic rhinitis. During the same season a second study compared in a randomized way (2 parallel groups) the effect of Budesonide (Rhinocort Aqua) and Azelastine (Allergodil nasal spray) in a group of 14 patients. Results showed that both antihistamines, applied topically of dosed orally, reduced sneezing even when significant increases of histamine concentration in nasal secretions were evidenced immediately after NAC. When a combination of Cetirizine and Cimetidine was administered, a significant (p < 0.01) reduction of nasal airway resistance and increase of nasal airflow after NAC were demonstrated as well. In addition, topical application of Budesonide showed a strong (p < 0.01) effect on the infiltration and activation of eosinophils during the season, and on tryptase release after NAC. These effects lasted at least for one week after therapy. PMID:8669268

  7. The anatomical and functional relationship between allergic conjunctivitis and allergic rhinitis

    PubMed Central

    Bielory, Leonard

    2013-01-01

    There are numerous anatomic connections between the allergic conjunctivitis and allergic rhinitis. The most obvious reason is the physical connection via the nasolacrimal apparatus. However, a closer look at innervation, circulatory, lymphatic, and neurogenic systems reveals much more than a physical connection. The eye is richly innervated by parasympathetic nerves that enter the eyes after traveling in conjunction with the parasympathetic input to the nasal cavity. Parasympathetic innervation governing the tear film and nasal secretion can intersect at the pterygopalatine ganglion. Neurogenic inflammation affects both the eye and the nose as evidenced by the presence of the same neurogenic factors. Venous flow is in the SOV area connecting the eye and the nose, once thought to be without valves. In the past, this thinking is the basis for concern about the danger triangle of the face. Recent literature has shown otherwise. Although valves are present, there are still pathways where bidirectional flow exists and a venous connection is made. The most likely area for venous communication is the pterygoid plexus and cavernous sinus. The venous flow and connections also offers a pathway for allergic shiners. Understanding the mutual connections between the nasal mucosa and the ocular surface can also affect treatment strategies. PMID:24498515

    Abietic acid (AA), one of the terpenoids isolated from Pimenta racemosa var. grissea, has been reported to have anti-inflammatory and immunomodulatory effects. However, the anti-allergic effects of AA remain unclear. The aim of this study was to investigate the anti-allergic effects of AA in an ovalbumin (OVA)-induced asthma murine model. The model of mouse asthma was established by induction of OVA. AA (10, 20, 40mg/kg) was administered by oral gavage 1h after the OVA treatment on days 21 to 23. At 24h after the last challenge, bronchoalveolar lavage fluid (BALF) and lung tissues were collected to assess pathological changes, cytokines production, and NF-κB expression. The results showed that AA attenuated lung histopathologic changes, inflammatory cells infiltration, and bronchial hyper-responsiveness. AA also inhibited OVA-induced the nitric oxide (NO), IL-4, IL-5, IL-13, and OVA-specific IgE production, as well as NF-κB activation. In conclusion, the current study demonstrated that AA exhibited protective effects against OVA-induced allergic asthma in mice and the possible mechanism was involved in inhibiting NF-κB activation.

    Several fruits have been reported to crossreact with latex antigen in latex allergy patients but little is known regarding tropical fruits in particular. Here we report the case of a 34-year old nurse who developed anaphylaxis following the ingestion of dried jackfruit (Artocarpus heterophyllus). The patient had a history of chronic eczema on both hands resulting from a regular wear of latex gloves. She and her family also had a history of atopy (allergic rhinitis and/or atopic dermatitis). The results of skin prick tests were positive for jackfruit, latex glove, kiwi and papaya, but the test was negative for banana. While we are reporting the first case of jackfruit anaphylaxis, further research needs to be conducted to identify the mechanisms underlying it. In particular, in-vitro studies need to be designed to understand if the anaphylaxis we describe is due to a cross reactivity between latex and jackfruit or a coincidence of allergy to these 2 antigens.

    Experimental allergic encephalomyelitis (EAE) can be readily induced passively by transfer of lymphocytes from neuroantigen immunized rats to naive recipients. This passively induced disease runs an acute, monophasic, self-limiting course, much the same as is usually seen in actively induced diseases. Here we examine the mechanisms regulating passive EAE. We report that splenectomy, thymectomy, and increasing age of recipients, manipulations which have been reported to influence recovery from actively induced EAE, have no effect on passively induced disease. EAE effector cells are not inactivated when transferred into recipients that have been actively sensitized and are beginning their recovery from clinical signs; this being a time when recovery associated suppressor cells are thought to be present. Finally, in the absence of suppressor T cells in both the recipient and in the transfer cell population, recovery from passive EAE still occurs. We conclude that suppressor T cells play no role in regulating passively induced EAE. PMID:2936807

    Occupational contact dermatitis in hair dressers and beauticians has increased in importance in the past years. Type IV-allergies against glyceryl monothioglycate components of permanent waves are most common. Other occupational allergens include bleach components such as ammonium persulfate and hair dye ingredients such as p-phenylenediamine (PPD) and p-toluylene-diamine (PTD) base. Allergies to hair dyes in customers of hair dressers have rarely been observed. Two female patients developed allergic contact dermatitis of the scalp and face after repeated use of Polycolor intensivtönung schwarz and of Movida color. We also review the current literature on type IV-allergies to components of hair dressing products components. PMID:11405157

    A 36-year-old female kitchenworker twice developed eczematous lesions corresponding exactly to the area around her neck where she had worn a wooden necklace. Contact dermatitis lasted longer than 1 week. The necklace consisted of 42 brown wooden beads and 63 other wooden parts, 0.5 to 3 cm diameter. Most parts could be identified as Cocobolo wood, Brazilian and East Indian rosewood, and teak. Patch tests with the pure constituents gave +3-reactions to three dalbergions and obtusaquinone, which are known to be the sensitizers of Cocobolo and the above-mentioned rosewoods. Because of these test results, the identification of the species by eye examination could be corroborated. Further detailed questioning revealed that the patient had played a recorder, probably made from Cocobolo (Dalbergia retusa), when a child, to which she unknowingly became allergic. PMID:9249295

    Allergic contact dermatitis (ACD) is a common skin disease that has significant socio-economic impact. ACD is mediated by a T-cell mediated inflammatory reaction. Langerhans cells (LCs) are an epidermal DCs subset specialized in antigen presentation. After hapten exposure, LCs play a major role as in induction adaptive immune response against allergens. LCs recognize, take up and process haptens and migrate to the local draining lymph nodes. However, LCs specific functions and the LCs migration to local draining lymph nodes are not yet clearly defined. Recent advance in the knowledge of LCs function has increased in the past decades including the evidence for a tolerogenic function of LCs. The present review will focus on the role for LCs response to contact allergens. PMID:21139551

    Foreign body neglected in the nasal cavity for many years leads to the formation of a rhinolith, which gradually increases in size. Nasal obstruction and persistent foul smelling nasal discharge usually are the main presenting symptoms, although some might be silent. This paper presents and discuss a case of 19-year-old female patient whose main complaint was nasal obstruction for many years and treated as allergic rhinitis. Diagnosis was confirmed with computed tomography scan, and it was removed endoscopically without complications. We think that proper examination, which includes endoscopic evaluation, should be done to reach the diagnosis. A computed tomography scan confirmed the diagnosis and helped in planning the best treatment option. PMID:27053994

    Glues based on cyanoacrylates are widely used as contact adhesives for metal, glass, rubber, plastics and textiles, as well for biological materials, including binding tissues and sealing wounds in surgery. In this paper, an apprentice cobbler with an occupational allergic contact dermatitis from an ethyl cyanoacrylate glue, in which the major monomer was shown to be the sensitizer, is reported. Initial patch testing with the cyanoacrylate glue dissolved in acetone with the Finn Chamber (aluminium) technique yielded false-negative reactions. Positive test reactions were obtained with the same preparations using Van der Bend chambers. With petrolatum as vehicle for the glue, there was no difference between Finn Chamber technique and Van der Bend chamber technique. The role of aluminium in the false-negative reactions is discussed.

    Platinum is used as a catalyst in the manufacture of silicone breast implants. Because platinum is recognized as a potent sensitizer in certain circumstances, some have expressed concern that women with silicone breast implants are exposed to platinum, which is causing allergic reactions. We searched the literature for information on the level of platinum in breast implants and reports of sensitization that clearly related to platinum in women with breast implants. We found no published report with convincing evidence that platinum causes allergic reactions in women with breast implants or that women with breast implants are any more likely to have allergic reactions than women without breast implants.

    Molecular topology has been applied to the search of QSAR models able to identify the anti-allergic activity of a wide group of heterogeneous compounds. Through the linear discriminant analysis and artificial neural networks, correct classification percentages above 85% for both the training set and the test set have been obtained. After carrying out a virtual screening with a natural product library, about thirty compounds with theoretical anti-allergic activity have been selected. Among them, hesperidin, naringin, salinomycin, sorbitol, curcumol, myricitrin, diosmin and kinetin stand out. Some of these compounds have already been referenced as having anti-allergic activity.

    The Allergic Rhinitis and its Impact on Asthma (ARIA) initiative has had a significant impact, by raising awareness of allergic rhinitis (AR) and improving the diagnosis and treatment of AR sufferers. ARIA classifies the severity of AR as "mild" or "moderate/severe" on the basis of "yes"/"no" answers to four questions. This two-point classification has been criticized as providing little guidance on patient management; patients with "mild" AR are unlikely to consult a physician, whereas the group of patients with "moderate/severe" seen by specialists is heterogeneous. These perceived shortcomings have prompted attempts to improve the ARIA classification or, by analogy with the Global Initiative for Asthma (GINA), adopt approaches based on "disease control" in AR. Even though "disease severity", "disease control" and "responsiveness to treatment" are different (albeit related) metrics, they are not mutually exclusive. Currently, there is no single, accepted definition, but we propose that "disease control" in AR can combine (i) measurements of the severity and/or frequency of daily or nocturnal symptoms, (ii) impairments in social, physical, professional and educational activities, (iii) respiratory function monitoring and (iv) exacerbations (e.g. unscheduled medical consultations and rescue medication use). Although control-based classifications have a number of limitations (e.g. their dependence on treatment compliance and the patient's psychological status), these instruments could be used as an adjunct to the ARIA severity classification and regional practice parameters. Here, we assess the strengths and weaknesses of the current two-level ARIA classification, analyze published proposals for its modification and review the literature on instruments that measure AR control. We conclude that there is a need for research in which severity is compared with control in terms of their effects on patient management. PMID:23419058

    Concomitant allergic reactions to multiple drugs are uncommon. We report the case of a 66-year-old woman who presented with concomitant sensitization to inhaled budesonide and oral nystatin presenting as allergic contact stomatitis and systemic allergic contact dermatitis. It is notable that one of the reactions was caused by oral nystatin, which generally is not considered to be allergenic due to its poor intestinal absorption. Diagnoses were confirmed on patch testing with histologic examination along with oral challenge testing. We also used challenge testing to rule out cross-reactivity among nystatin and other macrolide drugs, both antifungals and antibiotics. PMID:26919353

    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. -- 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. ► Particulate Cr

    Evidence suggests that possible imbalances in intestinal microbiota composition may be implicated in the occurrence of allergic diseases. Although several studies published until 2006 indicated a correlation between microbiota composition and allergic symptoms, it has not been possible to distinguish protective microorganisms from those associated with increased risk of allergic diseases. Therefore, the objective of this study was to review the studies published since 2007 that address the intestinal microbiota in allergic diseases. Twenty-one studies were identified after excluding those that performed a clinical intervention before stool collection. In the early microbiota of children who later developed allergies, lower bacterial diversity was observed, with a predominance of Firmicutes; a higher count of Bacteroidaceae; a higher prevalence of the anaerobic bacteria Bacteroides fragilis, Escherichia coli, Clostridium difficile, Bifidobacterium catenulatum, Bifidobacterium bifidum, and Bifidobacterium longum; and a lower prevalence of Bifidobacterium adolescentis, B. bifidum, and Lactobacillus. In the microbiota of allergic children whose intestinal microbiota was assessed at the onset of allergic symptoms, there was a higher count of Bacteroides; a lower count of Akkermansia muciniphila, Faecalibacterium prausnitzii, and Clostridium; a higher prevalence of B. adolescentis; a lower prevalence of B. catenulatum and Staphylococcus aureus; and a lower bacterial diversity.

    PubMed

    Modena, Brian D; Dazy, Kristen; White, Andrew A

    2016-08-01

    In a process known as overt degranulation, mast cells can release all at once a diverse array of products that are preformed and present within cytoplasmic granules. This occurs typically within seconds of stimulation by environmental factors and allergens. These potent, preformed mediators (ie, histamine, heparin, serotonin, and serine proteases) are responsible for the acute symptoms experienced in allergic conditions such as allergic conjunctivitis, allergic rhinitis, allergy-induced asthma, urticaria, and anaphylaxis. Yet, there is reason to believe that the actions of mast cells are important when they are not degranulating. Mast cells release preformed mediators and inflammatory cytokines for periods after degranulation and even without degranulating at all. Mast cells are consistently seen at sites of chronic inflammation, including nonallergic inflammation, where they have the ability to temper inflammatory processes and shape tissue morphology. Mast cells can trigger actions and chemotaxis in other important immune cells (eg, eosinophils and the newly discovered type 2 innate lymphocytes) that then make their own contributions to inflammation and disease. In this review, we will discuss the many known and theorized contributions of mast cells to allergic diseases, focusing on several prototypical allergic respiratory and skin conditions: asthma, chronic rhinosinusitis, aspirin-exacerbated respiratory disease, allergic conjunctivitis, atopic dermatitis, and some of the more common medication hypersensitivity reactions. We discuss traditionally accepted roles that mast cells play in the pathogenesis of each of these conditions, but we also delve into new areas of discovery and research that challenge traditionally accepted paradigms.

    2016-01-01

    Allergic rhinitis is estimated to affect 10%-20% of pediatric population and it is caused by the IgE-sensitization to environmental allergens, most importantly grass pollens and house dust mites. Allergic rhinitis can influence patient’s daily activity severely and may precede the development of asthma, especially if it is not diagnosed and treated correctly. In addition to subcutaneous immunotherapy, sublingual immunotherapy (SLIT) represents the only treatment being potentially able to cure allergic respiratory diseases, by modulating the immune system activity. This review clearly summarizes and analyzes the available randomized, double-blinded, placebo-controlled trials, which aimed at evaluating the effectiveness and the safety of grass pollen and house dust mite SLIT for the specific treatment of pediatric allergic rhinitis. Our analysis demonstrates the good evidence supporting the efficacy of SLIT for allergic rhinitis to grass pollens in children, whereas trials regarding pediatric allergic rhinitis to house dust mites present lower quality, although several studies supported its usefulness.

    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. PMID:26605551

    2016-02-01

    Allergic rhinitis is estimated to affect 10%-20% of pediatric population and it is caused by the IgE-sensitization to environmental allergens, most importantly grass pollens and house dust mites. Allergic rhinitis can influence patient's daily activity severely and may precede the development of asthma, especially if it is not diagnosed and treated correctly. In addition to subcutaneous immunotherapy, sublingual immunotherapy (SLIT) represents the only treatment being potentially able to cure allergic respiratory diseases, by modulating the immune system activity. This review clearly summarizes and analyzes the available randomized, double-blinded, placebo-controlled trials, which aimed at evaluating the effectiveness and the safety of grass pollen and house dust mite SLIT for the specific treatment of pediatric allergic rhinitis. Our analysis demonstrates the good evidence supporting the efficacy of SLIT for allergic rhinitis to grass pollens in children, whereas trials regarding pediatric allergic rhinitis to house dust mites present lower quality, although several studies supported its usefulness.

    Allergic diseases are sustained by a T-helper 2 polarization leading to interleukin-4 secretion, IgE-dependent inflammation, and mast cell and eosinophil activation. HLA-G molecules, both in membrane-bound and in soluble forms, play a central role in modulation of immune responses. Elevated levels of soluble HLA-G (sHLA-G) molecules are detected in serum of patients with allergic rhinitis to seasonal and perennial allergens and correlate with allergen-specific IgE levels, clinical severity, drug consumption, and response to allergen-specific immunotherapy. sHLA-G molecules are also found in airway epithelium of patients with allergic asthma and high levels of sHLA-G molecules are detectable in plasma and bronchoalveolar lavage of asthmatic patients correlating with allergen-specific IgE levels. Finally, HLA-G molecules are expressed by T cells, monocytes-macrophages, and Langerhans cells infiltrating the dermis of atopic dermatitis patients. Collectively, although at present it is difficult to completely define the role of HLA-G molecules in allergic diseases, it may be suggested that they are expressed and secreted by immune cells during the allergic reaction in an attempt to suppress allergic inflammation.

    The recent identification of genetic mutations leading to dysfunction of inflammatory and apoptotic pathways, has allowed to characterise a group of diseases, recognised as monogenic autoinflammatory syndromes. Among those, Blau syndrome (BS) and early-onset sarcoidosis (EOS) have been identified as familial and sporadic phenotypes of the same non-caseating granulomatous form. Both the diseases are caused by mutations in the CARD15/NOD2 gene, encoding the cytosolic NOD2 protein, one of the key molecules in the regulation of innate immunity. Clinical onset is typically located in the first years of life and phenotype is characterised by simultaneous or less articular, cutaneous and ocular non-caseating granulomatous inflammation, which can be variably associated with a heterogeneous systemic spectrum. The CARD15/NOD2 gene has also been identified as one of the genes linked to susceptibility to Crohn's disease (CD), a common polygenic inflammatory granulomatous bowel disease. The heightened nuclear factor-κB activity, found in the intestinal tissue of patients affected by CD, has probably a genetic cause related to several CARD15/NOD2 polymorphisms. Other substitutions in the CARD15/NOD2 gene have also been found in a recently described disorder, called NOD2-associated autoinflammatory disease, which shares several clinical characteristics with BS and EOS. This review attempts to describe these diseases on the basis of the most recent evidences. We described genetic and clinical aspects, mainly focusing on BS and EOS, the most representative diseases of autoinflammatory granulomatous diseases, with the ultimate purpose to expand their knowledge.

    Experiments were carried out to examine relationships between alveolar macrophage maturity and amounts of tissue factor (Clotting Factor III) in these cells under physiologic conditions and during immunologically induced pneumonitis. Using discontinuous density gradient centrifugation, alveolar macrophages from healthy rabbits were rapidly isolated into five subpopulations at different stages of maturation, as demonstrated by morphologic and morphometric evaluation. Very large amounts of tissue factor activity were found in fully mature cells that were purified in the lowest density subpopulation and assayed without preliminary in vitro stimulation or culture. In the remaining four subpopulations of increasing density, amounts of tissue factor were found to progressively diminish in direct correlation with declines of cell maturity. These differences at mean levels were as great as 35-fold. In addition, blood monocytes had less than 1/219 and less than 1/6 of the activity of the fully mature and the least mature subpopulations, respectively. After 16 h culture of the five isolated subpopulations in the absence of lymphokines or of significant numbers of lymphocytes, tissue factor activity increased in inverse correlation with the preincubation stage of cell maturity (2,387 and 109% in the least mature and most mature subpopulations, respectively). These increases required protein synthesis and were accompanied by morphologic and morphometric changes which indicated cellular maturation during the period of tissue factor activity generation in vitro, thus further demonstrating relationships between macrophage maturity and tissue factor content. In additional experiments, direct correlations between cell maturity and tissue factor activity content were also found in activated alveolar macrophage populations from rabbits with Bacillus Calmette Guering (BCG)-induced granulomatous pneumonitis. However, as compared with controls, the BCG populations had increased total

    Invasive aspergillosis is an important cause of morbidity and mortality in immunocompromised patients. Among primary immunodefiencies, chronic granulomatous disease (CGD) has the highest prevalence of invasive fungal diseases. Voriconazole is recommended for the primary treatment of invasive aspergillosis in most patients. In patients whose aspergillosis is refractory to voriconazole, therapeutic options include changing class of antifungal, for example using an amphotericin B formulation, an echinocandin, combination therapy, or further use of azoles. Posaconazole is a triazole derivative which is effective in Aspergillosis prophylaxis and treatment. Rarely, surgical therapy may be needed in some patients. Lesions those are contiguous with the great vessels or the pericardium, single cavitary lesion that cause hemoptysis, lesions invading the chest wall, aspergillosis that involves the skin and the bone are the indications for surgical therapy.Chronic granulomatous disease (CGD) is an inherited immundeficiency caused by defects in the phagocyte nicotinamide adenine dinucleotidephosphate (NADPH) oxidase complex which is mainstay of killing microorganisms. CGD is characterized by recurrent life-threatening bacterial and fungal infections and by abnormally exuberant inflammatory responses leading to granuloma formation, such as granulomatous enteritis, genitourinary obstruction, and wound dehiscence. The diagnosis is made by neutrophil function testing and the genotyping.Herein, we present a case with CGD who had invasive pulmonary aspergillosis refractory to voriconazole and liposomal amphotericine B combination therapy that was controlled with posaconazole treatment and pulmonary surgery.

    2016-01-01

    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

    α-Tocopherol blocks responses to allergen challenge in allergic adult mice, but it is not known whether α-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 α-tocopherol blocked development of allergic responses in offspring of allergic female mice. Allergic female mice were supplemented with α-tocopherol starting at mating. The pups from allergic mothers developed allergic lung responses, whereas pups from saline-treated mothers did not respond to the allergen challenge, and α-tocopherol supplementation of allergic female mice resulted in a dose-dependent reduction in eosinophils in the pup bronchoalveolar lavage and lungs after allergen challenge. There was also a reduction in pup lung CD11b+ dendritic cell subsets that are critical to development of allergic responses, but there was no change in several CD11b− dendritic cell subsets. Furthermore, maternal supplementation with α-tocopherol reduced the number of fetal liver CD11b+ dendritic cells in utero. In the pups, there was reduced allergen-induced lung mRNA expression of IL-4, IL-33, TSLP, CCL11, and CCL24. Cross-fostering pups at the time of birth demonstrated that α-tocopherol had a regulatory function in utero. In conclusion, maternal supplementation with α-tocopherol reduced fetal development of subsets of dendritic cells that are critical for allergic responses and reduced development of allergic responses in pups from allergic mothers. These results have implications for supplementation of allergic mothers with α-tocopherol. PMID:25015974

    Respiratory and cutaneous adverse reactions to mint can result from several different mechanisms including IgE-mediated hypersensitivity, delayed-type hypersensitivity (contact dermatitis), and nonimmunologic histamine release. Reactions to cross-reacting plants of the Labiatae family, such as oregano and thyme, as well as to the chemical turpentine, may clue the clinician in on the diagnosis of mint allergy. Contact dermatitis can result from menthol in peppermint. Contact allergens have been reported in toothpastes, which often are mint-flavored. Allergic asthma from mint is less well-recognized. A case of a 54-year-old woman with dyspnea on exposure to the scent of peppermint is presented in whom mint exposure, as seemingly innocuous as the breath of others who had consumed Tic Tac candies, exacerbated her underlying asthma. This case highlights the importance of testing with multiple alternative measures of specific IgE to mint, including skin testing with mint extract, and skin testing with fresh mint leaves. Additionally, this cases suggests that asthma can result from inhaling the scent of mint and gives consideration to obtaining confirmatory pre- and postexposure pulmonary function data by both impulse oscillometry and spirometry.

    The rapid rise in childhood allergies (atopy) in Westernized nations has implicated associated environmental exposures and lifestyles as primary drivers of disease development. Culture-based microbiological studies indicate that atopy has demonstrable ties to altered gut microbial colonization in very early life. Infants who exhibit more severe multisensitization to food- or aero-allergens have a significantly higher risk of subsequently developing asthma in childhood. Hence an emerging hypothesis posits that environment- or lifestyle-driven aberrancies in the early-life gut microbiome composition and by extension, microbial function, represent a key mediator of childhood allergic asthma. Animal studies support this hypothesis. Environmental microbial exposures epidemiologically associated with allergy protection in humans confer protection against airway allergy in mice. In addition, gut microbiome-derived short-chain fatty acids produced from a high-fiber diet have been shown to protect against allergy via modulation of both local and remote mucosal immunity as well as hematopoietic antigen-presenting cell populations. Here we review key data supporting the concept of a gut-airway axis and its critical role in childhood atopy. PMID:27027953

    Exposure to hair dye is the most frequent route of sensitisation to para-phenylenediamine (PPD), a common contact allergen. International studies have examined the profile of PPD, but Australian-sourced information is lacking. Patients are often dissatisfied with advice to stop dyeing their hair. This study examines patients' characteristics, patch test results and outcomes of PPD allergy from a single Australian centre, through a retrospective analysis of patch test data from 2006 to 2013 at the Liverpool Hospital Dermatology Department. It reviews the science of hair dye allergy, examines alternative hair dyes and investigates strategies for hair dyeing. Of 584 patients, 11 were allergic to PPD. Our PPD allergy prevalence rate of 2% is at the lower end of international reported rates. About half these patients also react to para-toluenediamine (PTD). Affected patients experience a significant lifestyle disturbance. In all, 78% tried alternative hair dyes after the patch test diagnosis and more than half continued to dye their hair. Alternative non-PPD hair dyes are available but the marketplace can be confusing. Although some patients are able to tolerate alternative hair dyes, caution is needed as the risk of developing an allergy to other hair dye ingredients, especially PTD, is high. PMID:25302475

    Treatment with beclomethasone dipropionate aerosol (BDA), 50 mug four times daily in each nostril, was compared with placebo therapy in a double-blind non-crossover trial of 30 matched patients with allergic rhinitis induced by ragweed pollen. The trial was started at the beginning of the ragweed season and continued for 42 days. Response to treatment was assessed from information on daily diary cards, weekly objective measurements of nasal patency and measurement of total eosinophil count (TEC) before treatment and at week 4. Patients in the BDA group had significantly less (P less than 0.05) sneezing, rhinorrhea and nasal stuffiness at 36 days, cough at 10 days and antihistamine consumption at 17 days. There was no significant difference between the groups in eye symptoms, nasal airway inspiratory resistance, maximum inspiratory nasal flow or TEC. Overall comparison with previous pollen seasons by the patients indicated moderate to great improvement in 86% of the BDA group and in 13% of the placebo group (P less than 0.01). Minor side effects were noted by two patients in each group. PMID:782679

    Allergen immunotherapy is effective in patients with allergic rhinitis (AR) and, unlike antiallergic drugs, has been shown to modify the underlying cause of the disease, with proved long-term benefits. Subcutaneous immunotherapy (SCIT) has been the gold standard, whereas sublingual immunotherapy (SLIT) has emerged as an effective and safe alternative. Previous Cochrane systematic reviews and meta-analyses have confirmed that both SLIT and SCIT are effective in patients with seasonal AR, whereas evidence for their efficacy in patients with perennial disease has been less convincing. Recent large, adequately powered trials have demonstrated reductions in both symptoms and use of rescue medication in patients with seasonal and those with perennial AR. Here we appraise evidence for SCIT versus SLIT based on indirect evidence from Cochrane reviews and recent well-powered double-blind, randomized controlled trials versus placebo and the limited direct evidence available from randomized blind head-to-head comparisons. At present, based on an overall balance of efficacy and side effects, the patient is in equipoise. Pending definitive comparative trials, choice might be determined largely by the local availability of SCIT and SLIT products of proved value and personal (patient) preference. PMID:26853126

    Olfactory dysfunction is a key symptom in patients with allergic rhinitis (AR). Despite the implications for quality of life, relatively few articles have tested olfactory function in their investigations. The current systematic review aimed to investigate the following 2 questions: (1) What does AR do to human olfaction? (2) How effective is the treatment of AR in restoring the sense of smell? A comprehensive literature search was performed, and human studies of any design were included. A total of 420 articles were identified, and 36 articles were considered relevant. Data indicate that the frequency of olfactory dysfunction increases with the duration of the disorder, and most studies report a frequency in the range of 20% to 40%. Although olfactory dysfunction does not appear to be very severe in patients with AR, its presence seems to increase with the severity of the disease. There is very limited evidence that antihistamines improve olfactory function. In addition, there is limited evidence that topical steroids improve the sense of smell, especially in patients with seasonal AR. This is also the case for specific immunotherapy. However, many questions remain unanswered because randomized controlled trials are infrequent and only a few studies rely on quantitative measurement of olfactory function. PMID:26409662

    Asthma is characterized by lung inflammation caused by complex interaction between the immune system and environmental factors such as allergens and inorganic pollutants. Recent research in this field is focused on discovering new biomarkers associated with asthma pathogenesis. This review illustrates updated research associating biomarkers of allergic asthma and their potential use in systems biology of the disease. We focus on biomolecules with altered expression, which may serve as inflammatory, diagnostic and therapeutic biomarkers of asthma discovered in human or experimental asthma model using genomic, proteomic and epigenomic approaches for gene and protein expression profiling. These include high-throughput technologies such as state of the art microarray and proteomics Mass Spectrometry (MS) platforms. Emerging concepts of molecular interactions and pathways may provide new insights in searching potential clinical biomarkers. We summarized certain pathways with significant linkage to asthma pathophysiology by analyzing the compiled biomarkers. Systems approaches with this data can identify the regulating networks, which will eventually identify the key biomarkers to be used for diagnostics and drug discovery. PMID:24409194

    Allergic rhinitis is a widespread allergic disease, with 35-40% prevalence in the world population. It is characterized with increasing frequency, particularly in children's population. Goal of the work - study of psycho-emotional profile in adolescents with allergic rhinitis of different severity. Single-stage research was conducted, in compliance with the ethical norms. Study included 86 children (41% girls and 45% boys) of age from 11 to 13 years with allergic rhinitis of different severity and 30 healthy children. For the purpose of study of the patients' psychological profile Esenek Personality Questionnaire (EPQ) intended for assessment of characterological and individual psychological features in children and adolescents (10-15 years) was used. Psycho-emotional sphere of the adolescents with allergic rhinitis was assessed also by Psychopathologic Symptom Checklist (Symptom Checklist-90-Revised-SCL-90-R). Clinical scale of self-assessment of psychical condition is widely applied in ambulatory and hospital practice. At the final stage of research the mathematical-statistical data processing was provided by means of SPSS/v12 software package. According to the research results, susceptibility to significant and mild introversion was identified in severe and average AR cases. Such patients are often locked into their inner world. These children are reserved, communicate with the parents and close friends only. They make decisions with due care, love order, control their emotions, are pessimistic and rarely aggressive. Results of neuroticism study by G. Esenek techniques are provided in Table. Neuroticism is associated with the lability of nervous system, characterizes emotional condition or emotional lability (emotional stability or instability). According to the research results, allergic rhinitis is characterized with emotional instability, anxiety, as manifested by unsatisfactory adaptation, instable nature, depression, low resistance to the stress situations

    Necrotising meningoencephalitis (NME) and granulomatous meningoencephalitis (GME) are idiopathic inflammatory diseases of the canine central nervous system (CNS). Typical NME occurs predominantly in small breeds of dogs, such as Pug, Maltese and Yorkshire terriers. Although there is no specific breed predisposition to GME, toy and terrier breeds appear to be overrepresented. Recent molecular investigations have identified genetic risk factors for NME in Pug, Maltese and other toy breed dogs; however, details of the pathogenesis of this disease remain to be clarified. NME is characterised pathologically by necrotic lesions with mononuclear cell infiltration in the meninges and perivascular spaces. On the basis of the distribution pattern of major necrotic foci, NME can be divided into cortex dominant and white matter dominant types; the latter is designated necrotising leucoencephalitis (NLE). Lesions in GME are characterised by the accumulation of lymphocytes and macrophages with epithelioid morphology, forming granulomas around blood vessels. Some common genetic factors and/or some additional triggers, such as infection or vaccination, may play a role in the pathogenesis of NME, NLE and GME; however, the host immune responses may define the pathological phenotypes. Different cytokine and chemokine responses are seen in NME, NLE and GME, whilst autoantibodies against astrocytes are detected predominantly in NME. This review focuses on the pathological and immunological characteristics of these canine idiopathic inflammatory CNS disorders. PMID:27240919

    Background: Chronic granulomatous invasive fungal rhinosinusitis (CGIFRS) is a rare disease. The underlying immune responses that drive the development of CGIFRS, as opposed to successful pathogen clearance and controlled inflammation, are not currently known. Objective: To characterize the immune responses associated with CGIFRS. Methods: In addition to a battery of basic investigations, more in-depth immunologic testing involves ex vivo whole-blood stimulation with the polyclonal T-cell mitogen phytohemagglutinin and fungal antigens with interleukin (IL) 12, was undertaken to investigate cell-mediated immune responses associated with CGIFRS. Results: Ex vivo whole-blood stimulation with the polyclonal T-cell mitogen phytohemagglutinin and fungal antigens with IL-12 identified reduced interferon gamma and increased IL-17A levels within the supernatant, which indicated increased in vivo T-helper (Th)17 responses and impaired Th1 responses compared with healthy controls. Conclusion: These findings suggest that the development of CGIFRS may be associated with an abnormally exaggerated host Th17 response, which caused failure to clear the fungal pathogen with refractory fungal infection of mucosal membranes, resulting in chronic tissue inflammation.

    Chronic granulomatous disease (CGD), a rare inherited disorder of the innate immune system, results from mutations in any one of the five genes encoding the subunits of the nicotinamide adenine dinucleotide phosphate-oxidase (NADPH) oxidase enzyme, and is characterized by recurrent life-threatening bacterial and fungal infections. Molecular analysis of 14 Omani CGD patients from 10 families, diagnosed to have CGD on clinical (recurrent infections) and biochemical grounds (positive for both the nitroblue tetrazolium (NBT) test and the dihydrorhodamine (DHR-1,2,3 assay), revealed that only one patient had X-linked CGD, with a large deletion involving both the gp91-phox gene (CYBB) and the McLeod gene (XK). The remaining 13 patients were all homozygotes from a previously described c.579G>A (p.Trp193X) mutation in the NCF1 gene on chromosome 7, responsible for autosomal recessive CGD (AR-CGD). Although X-linked CGD is the most common type of CGD disorder in most population groups, AR-CGD is the most prevalent type in Oman. PMID:24446915

    Chronic granulomatous disease (CGD) is a primary immunodeficiency disorder characterized by defective microbial killing in phagocytes. Long-term prognosis for CGD patients is generally poor, highlighting the need to develop minimally toxic, curative therapeutic approaches. We here describe the establishment of a mouse model in which X-linked CGD can be cured by allogeneic bone marrow transplantation. Using a combination of non-myeloablative-dose total body irradiation and a single injection of anti-CD40 ligand monoclonal antibody, transplantation of whole bone marrow cells achieved long-lasting mixed chimerism in X-linked CGD mice in a haploidentical transplantation setting. Stable mixed chimerism was maintained for up to 1 year even at a low range (<20 % donor cells), indicating induction of donor-specific tolerance. The regimen induced mild myelosuppression without severe acute complications. Stable chimerism was therapeutic, as it suppressed cutaneous granuloma formation in an in vivo test suited for evaluation of treatment efficacy in murine CGD models. These results warrant future development of a simplified allogeneic hematopoietic cell transplantation regimen that would benefit CGD patients by allowing the use of haploidentical donor grafts without serious concerns of severe treatment-related toxicity.

    A girl presented during childhood with a single course of extensive chickenpox and moderate albeit recurrent pneumonia in the presence of idiopathic CD4+ T lymphocytopenia (ICL). Her clinical condition remained stable over the past 10 years without infections, any granulomatous disease, or autoimmunity. Immunophenotyping demonstrated strongly reduced naive T and B cells with intact proliferative capacity. Antibody reactivity on in vivo immunizations was normal. T-cell receptor-Vβ repertoire was polyclonal with a very low content of T-cell receptor excision circles (TRECs). Kappa-deleting recombination excision circles (KRECs) were also abnormal in the B cells. Both reflect extensive in vivo proliferation. Patient-derived CD34+ hematopoietic stem cells could not repopulate RAG2(-/-)IL2Rγc(-/-) mice, indicating the lymphoid origin of the defect. We identified 2 novel missense mutations in RAG1 (p.Arg474Cys and p.Leu506Phe) resulting in reduced RAG activity. This report gives the first genetic clue for ICL and extends the clinical spectrum of RAG mutations from severe immune defects to an almost normal condition. PMID:21502542

    Chronic granulomatous disease (CGD) is an inherited group of disorders in which phagocytic leukocytes (neutrophils, eosinophils, monocytes, and macrophages) fail to undergo a respiratory burst when stimulated. The products of the respiratory burst, which include superoxide and hypochlorous acid, play a critical role in killing pathogenic bacteria, fungi, and parasites. As a result of the failure to activate the respiratory burst in their phagocytes, most CGD patients suffer from severe recurrent infections. While all CGD patients share this severe defect, there is substantial heterogeneity in the molecular mechanisms responsible. The enzyme that catalyzes the respiratory burst, NADPH oxidase, has been extensively characterized and found to consist of at least four subunits: gp91-phox and p22-phox (the two subunits of a low potential cytochrome b that is the terminal electron carrier of the oxidase) as well as p47-phox and p67-phox (two cytosolic oxidase components). CGD is caused by a defect in any one of these four components, thus explaining the previously confusing genetic heterogeneity of this disorder. In approximately thirty reported cases, the underlying mutations involving these oxidase components have been identified. The current understanding of the molecular basis of CGD is reviewed in the context of a recently completed Phase III clinical trial establishing the efficacy of recombinant human interferon gamma in the treatment of CGD.

    Hyper-immunoglobulin (Ig)E syndrome (HIES) is a primary immunodeficiency associated with mutations in STAT3 resulting in impaired development of T helper type 17 (Th17) lymphocytes. HIES patients with a reduced frequency of Th17 cells present with infections caused by Staphylococcus aureus and/or Candida strains. The same spectrum of pathogens is present in patients with chronic granulomatous disease (CGD).We analysed the characteristics of the Th17 compartment in HIES and CGD. HIES patients showed very low numbers of Th17 cells. By contrast, the frequency of Th17 cells and production of Th17-derived cytokines was significantly higher among CGD patients when compared to both control samples and HIES. Naive CD4(+) cells in CGD patients had a normal capacity to differentiate into IL-17-producing cells and the numbers of Th17 cells in the CGD patients normalized following successful bone marrow transplantation. Our findings complement recent data on the importance of Th17 cells for elimination of infections with C. albicans and S. aureus. PMID:21910722

    Schistosoma mansoni egg-induced inflammation is accompanied by TH2 cell polarization and development of fibrotic granulomas in host tissue. The interleukin (IL)-4 receptor α (IL-4Rα), which mediates IL-4 and IL-13 signaling, is essential for granulomatous pathology through a putative CD4+ T-cell-dependent mechanism. In this study, we asked whether CD4+ T-cell-specific IL-4Rα-deficient mice (LckCreIL-4Rα−/lox) developed granulomas and egg-driven collagen production. Although eosinophilia and goblet cell hyperplasia were impaired in LckCreIL-4Rα−/lox mice, there was no reduction in size or collagen content of lung and liver granulomas. The lack of CD4+ T-cell IL-4Rα expression caused significant increases in interferon-γ-producing cells, inducible nitric-oxide synthetase production, and hepatic damage, compared with similarly infected wild-type mice. Interestingly, this TH1-associated liver injury did not lead to premature mortality in this strain. Instead, lower levels of serum endotoxin in LckCreIL-4Rα−/lox mice suggest that intestinal barrier function may be the dominant factor for survival during natural infection. PMID:17071593

    Blau syndrome (MIM 186580), first described in a large, three-generation kindred, is an autosomal, dominantly inherited disease characterized by multiorgan, tissue-specific inflammation. Its clinical phenotype includes granulomatous arthritis, skin rash, and uveitis and probably represents a subtype of a group of clinical entities referred to as {open_quotes}familial granulomatosis.{close_quotes} It is the sole human model with recognizably Mendelian inheritance for a variety of multisystem inflammatory diseases affecting a significant percentage of the population. A genomewide search for the Blau susceptibility locus was undertaken after karyotypic analysis revealed no abnormalities. Sixty-two of the 74-member pedigree were genotyped with dinucleotide-repeat markers. Linkage analysis was performed under dominant model of inheritance with reduced penetrance. The marker D16S298 gave a maximum LOD score of 3.75 at {theta} = .04, with two-point analysis. LOD scores for flanking markers were consistent and placed the Blau susceptibility locus within the 16p12-q21 interval. 46 refs., 3 figs., 3 tabs.

    Recent advances in targeting BRAF mutations, which occur in roughly 50% of the melanomas, have improved response rates and overall survival in patients with advanced disease. With the increasingly extensive use of the drug, new, nonpreventable, cutaneous and noncutaneous toxicities keep arising as infrequent adverse effects. We report a 55-year-old man with a history of metastatic melanoma treated with the dabrafenib who presented, 10 months after the initiation of the treatment, with erythematous, slightly squamous, round plaques on his upper trunk and on his left upper arm. Two skin biopsies from the lesions revealed a granulomatous dermatitis in the superficial reticular dermis. One of them showed admixed abundant melanophages from tumoral melanosis. No melanoma cells were seen in any of the specimens. No interruption of the treatment was necessary. Our observation indicates that such a response may represent a positive immune activation triggered by BRAF inhibitors. The erythematous rash was initially concerning for progression of metastatic disease, which suggests that a close monitoring of the patients with advanced melanomas treated with vemurafenib is advisable to prevent unnecessary discontinuation of the therapy.

    Background. Chronic granulomatous disease (CGD) is an inherited disorder of the nicotinamide adenine dinucleotide phosphate oxidase that leads to defective production of microbicidal superoxide and other oxidative radicals, resulting in increased susceptibility to invasive infections, especially those due to fungi. Methods. Geosmithia argillacea was identified from cultured isolates by genomic sequencing of the internal transcribed spacer region. Isolates previously identified as Paecilomyces variotii, a filamentous fungus closely resembling G. argillacea, were also examined. Results. We identified G. argillacea as the cause of invasive mycosis in 7 CGD patients. In 5 cases, the fungus had been previously identified morphologically as P. variotii. All patients had pulmonary lesions; 1 had disseminated lesions following inhalational pneumonia. Infections involved the chest wall and contiguous ribs in 2 patients and disseminated to the brain in 1 patient. Four patients with pneumonia underwent surgical intervention. All patients responded poorly to medical treatment, and 3 died. Conclusions. We report the first cases of invasive mycosis caused by G. argillacea in CGD patients. G. argillacea infections in CGD are often refractory and severe with a high fatality rate. Surgical intervention has been effective in some cases. G. argillacea is a previously underappreciated and frequently misidentified pathogen in CGD that should be excluded when P. variotii is identified morphologically. PMID:21367720

    Background: Chronic granulomatous disease (CGD) is an immune disorder that affects phagocytes. It is characterized by recurrent or persistent bacterial and fungal infections. Reports of tuberculosis (TB) in patients with CGD are rare. In developing countries, where TB is endemic, possibility of other chronic infections is often overlooked by physicians. Case Description: We report the case of a 4-year-old boy who had recurrent respiratory infections and episodes of headache. He was put on antituberculosis (ATT) drugs without microbiological or pathological evidence 2 months prior to presentation. The child did not improve and was brought to our hospital where a computed tomography scan revealed multiple cerebral abscesses. These abscesses were excised. The microbiological specimen was determined to be positive for Aspergillus fumigatus. His tracheal aspirate was positive for Mycobacterium tuberculosis polymerase chain reaction assay. Further work-up confirmed the diagnosis of CGD in the child. Conclusion: This report describes the course of the patient's illness in order to highlight the challenges associated with the management of these infections. We also aim to stress on the importance of pathological diagnosis before starting a therapy. PMID:27308089

    Chronic granulomatous disease (CGD) is a clinical syndrome of recurrent bacterial and fungal infections caused by a rare disorder of phagocytic cells. In CGD, the phagocytes are unable to generate oxygen radicals after stimulation of these cells, due to a defect in the NADPH oxidase system. This NADPH oxidase is a multicomponent enzyme of at least four subunits, of which the β-subunit of cytochrome b558, gp91-phox, is encoded by an X-linked gene (called CYBB). We report here five patients from two families; in each family we found a different mutation in the promoter region of CYBB. Both mutations prevented the expression of gp91-phox in the patients' neutrophils and thus caused inability of these cells to generate oxygen radicals. However, the mutations left the gp91-phox expression and the function of the NADPH oxidase in the patients' eosinophils intact. The relatively mild course of the CGD in these patients can probably be attributed to the fact that the eosinophils have retained their oxidative capacity. Furthermore, our results indicate that neutrophils and eosinophils differ in their regulation of gp91-phox expression. PMID:11122248

    Summary Background The aim of this study is to compare the clinical course of idiopathic granulomatous mastitis (IGM) treated with low-dose oral corticosteroid therapy alone as opposed to treatment with low-dose corticosteroid therapy followed by surgery. Patients and Methods 37 patients were treated with an approach that consisted of methylprednisolone at a dose of 0.5 mg/kg/day followed by wide excision, and 23 patients were treated with an approach that consisted only of methylprednisolone. The treatment efficacy was compared between the two groups. Results Clinical and radiological regression was reported in all patients with steroid therapy, and the regression rate had a median of 75% (25–100%). No recurrence was observed in patients who were treated with wide surgical excision after steroid therapy during the median follow-up period of 38 (22–78) months. The control group of 23 patients was treated only with steroid therapy, and 7 (30%) of these patients experienced recurrence in the follow-up period (p < 0.001). Conclusions Steroid therapy was effective in the treatment of IGM by reducing the lesion size and extent. With regard to the current treatment options available for IGM, surgical excision after steroid therapy seems the better treatment option compared to steroid therapy without surgical excision. This treatment sequence reduces the rate of recurrence. PMID:25759614

    We present 20 patients in whom drug therapy was associated with interstitial histiocytic infiltrates with variable degeneration of collagen and elastic fibers mimicking early lesions of granuloma annulare (GA). Most patients had a reproducible clinical presentation comprising erythematous-to-violaceous, nonpruritic plaques, often with an annular pattern, predominantly involving inner aspects of the arms, medial thighs and intertriginous areas. The most frequent clinical differential diagnoses included cutaneous T cell lymphoma, erythema annulare centrifigum (EAC), GA, and lupus erythematosus. A drug reaction was suspected in only 3 cases. The implicated drug classes included calcium channel blockers, angiotensin converting enzyme inhibitors, beta-blockers, lipid-lowering agents, antihistamines, anticonvulsants and antidepressants. Patients were often on two or more of these drugs; all have been associated with pseudolymphomatous infiltrates of the skin, the presumptive basis of which is iatrogenic pertubation of immune function. The defining histomorphology was diffuse infiltration of the interstitium by lymphocytes and histiocytes with piecemeal fragmentation of collagen and elastic fibers in concert with a vacuolar interface dermatitis. Ten cases showed intermediate and transformed lymphocytes with hyperchromatic convoluted nuclei disposed interstitially within the dermis or along the dermoepiderma junction with variable epidermotropism. In the 15 patients who discontinued the implicated drug, lesional resolution occurred. We propose the designations interstitial granulomatous drug reaction for this novel cutaneous reaction pattern.

    Invasive aspergillosis is a major threat to patients suffering from impaired neutrophil function, with Aspergillus fumigatus being the most common species causing this life-threatening condition. Patients with chronic granulomatous disease (CGD) not only develop infections with A. fumigatus, but also exhibit a unique susceptibility to infection with the normally nonpathogenic species Aspergillus nidulans. In this study, we compared the inflammatory cytokine response of peripheral blood mononuclear cells (PBMCs) from healthy and CGD patients to these two fungal species. CGD patients displayed evidence for a chronic hyperinflammatory state as indicated by elevated plasma IL-1β and TNF-α levels. PBMCs isolated from CGD patients secreted higher levels of IL-1β and TNF-α in response to A. nidulans as compared with A. fumigatus. The presence or absence of melanin in the cell wall of A. nidulans did not alter the cytokine release by healthy or CGD PBMCs. In contrast, A. fumigatus mutants lacking melanin stimulated higher levels of proinflammatory cytokine release from healthy, but not CGD PBMCs. Purified cell wall polysaccharides of A. nidulans induced a much higher level of IL-1β secretion by CGD PBMCs than did cell wall polysaccharides isolated from A. fumigatus. Using modified A. nidulans strains overexpressing galactosaminogalactan, we were able to show that the increased secretion of inflammatory cytokines by CGD PBMCs in response to A. nidulans are a consequence of low levels of cell wall-associated galactosaminogalactan in this species.

    Granulomatous mastitis (GM) is a rare chronic inflammatory breast condition with unknown etiology. There is still no generally accepted optimal treatment for GM. Corticosteroid treatment and/or wide excision is most commonly reported in the literature. Incision and drainage or limited excision alone has little benefit because of a strong tendency of recurrence. Corticosteroids also have a high failure rate and possible side effects. In the current series, we treated GM patients without corticosteroids, except for one patient. We also devised multidirectional deep drainage for advanced and complicated abscesses, which are characteristic of GM. This retrospective study included 13 women who met the required histologic criteria of GM. The mean age of the patients was 41 years. All of the patients were premenopausal. Six patients had breast-fed in the last 5 years. Five patients were under medication with antidepressants. A total of 11 patients developed abscesses during the clinical course, and the abscesses penetrated the retromammary space in 4 patients. We treated 2 of these 4 patients with multidirectional deep drainage and obtained complete remission in 5 and 6.5 months, respectively. These times were much shorter than those in the other 2 patients. The time to resolution in 11 patients was 4 to 28 months. This overall outcome was comparable with that of corticosteroid treatment reported in the literature. Because the natural history of GM is thought to be self-limiting, close observation and minimally required drainage of abscesses without corticosteroid administration remain the treatment modality of choice.

    Tuberculosis (TB) is a dangerous infectious disease characterized by a tight interplay between mycobacteria and host cells in granulomatous lesions (granulomas) during the latent, asymptomatic stage of infection. Mycobacterium-host cell relationships were analyzed in granulomas obtained from various organs of BALB/c mice with chronic TB infection caused by in vivo exposure to the Bacillus Calmette-Guérin (BCG) vaccine. Acid-fast BCG-mycobacteria were found to be morphologically and functionally heterogeneous (in size, shape, and replication rates in colonies) in granuloma macrophages, dendritic cells, and multinucleate Langhans giant cells. Cord formation by BCG-mycobacteria in granuloma cells has been observed. Granuloma macrophages retained their ability to ingest damaged lymphocytes and thrombocytes in the phagosomes; however, their ability to destroy BCG-mycobacteria contained in these cells was compromised. No colocalization of BCG-mycobacteria and the LysoTracker dye was observed in the mouse cells. Various relationships between granuloma cells and BCG-mycobacteria were observed in different mice belonging to the same line. Several mice totally eliminated mycobacterial infection. Granulomas in the other mice had mycobacteria actively replicating in cells of different types and forming cords, which is an indicator of mycobacterial virulence and, probably, a marker of the activation of tuberculous infection in animals.

    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

    Background There is conflicting evidence that traffic-related air pollution is a risk factor for allergic conditions. Few studies have investigated this in adults. In adults, a high proportion of asthma, rhinitis and eczema is triggered by non-allergic factors. We investigated traffic as a risk factor for allergic versus non-allergic asthma and rhinitis, and eczema, in adults. A questionnaire from 2000 (n = 9319, 18–77 years) provided individual data about disease outcome and self-reported traffic exposure. Additional exposure assessments were obtained using Geographical Informations Systems (GIS). Residential addresses were linked to the national Swedish Road Database and to a pollutant database with modelled annual means of NOx (Nitrogen Oxids). Results Living within 100 m from a road with a traffic intensity of >10 cars/min (24 hour mean) was associated with prevalence of current asthma reported to be triggered by allergic factors (OR = 1.83, 95% CI = 1.23–2.72) and with allergic rhinitis (OR = 1.30, 95%CI = (1.05–1.61). No relation was seen with asthma or rhinitis triggered by other factors. Living within 100 m of a road with >10 cars/min was also associated with hand-eczema during the last 12 months (OR = 1.63, 95% CI = 1.19–2.23), but not with allergic eczema or diagnosed hand-eczema. Consistent results were seen using self-reported traffic, but the associations with NOx were less consistent. Conclusion Exposure to traffic was associated with a higher prevalence of allergic asthma and allergic rhinitis, but not with asthma or rhinitis triggered by non-allergic factors. This difference was suggested by the overall pattern, but only clear using GIS-measured traffic intensity as a proxy for traffic exposure. An association was also found with hand-eczema during the last 12 months. We suggest that asthma and rhinitis should not be treated as homogenous groups when estimating effects from traffic in adults. PMID:19419561

    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

    The prevalence of allergic disease has increased dramatically in Western countries over the past few decades. The hygiene hypothesis, whereby reduced exposure to microbial stimuli in early life programs the immune system toward a Th2-type allergic response, is suggested to be a major mechanism to explain this phenomenon in developed populations. Such microbial exposures are recognized to be critical regulators of intestinal microbiota development. Furthermore, intestinal microbiota has an important role in signaling to the developing mucosal immune system. Intestinal dysbiosis has been shown to precede the onset of clinical allergy, possibly through altered immune regulation. Existing treatments for allergic diseases such as eczema, asthma, and food allergy are limited and so the focus has been to identify alternative treatment or preventive strategies. Over the past 10 years, a number of clinical studies have investigated the potential of probiotic bacteria to ameliorate the pathological features of allergic disease. This novel approach has stemmed from numerous data reporting the pleiotropic effects of probiotics that include immunomodulation, restoration of intestinal dysbiosis as well as maintaining epithelial barrier integrity. In this mini-review, the emerging role of probiotics in the prevention and/or treatment of allergic disease are discussed with a focus on the evidence from animal and human studies. PMID:23049509

    Type III interferons (IFNs), or IFN-λ, are known to have potent antiviral and antiproliferative activities. It inhibits viral replication and upregulates cytotoxic responses to virally infected cells. Besides these characteristics, IFN-λ also has additional activities in the immune system. In fact, it induces the proliferation of Foxp3-expressing regulatory T cells mediated in part by dendritic cells and inhibit the production of IL-5 and IL-13 in vitro. Regulatory T cells and the Th2 cytokines like IL-5 and IL-13 play important roles in the pathogenesis of allergic asthma. In humans, there seems to be an inverse link between IFN-λ and the severity of allergic asthma and allergic asthma exacerbations. Asthmatic patients, without a detectable viral infection show an inverse correlation between IL-28 and IL-29 mRNA levels and severity of allergic responses in the airways. These additional features of IFN-λ that affect the adaptive immune system make it a potential immunotherapeutic agent for the treatment of allergic asthma. PMID:25592858

    Phospholipase A2 (sPLA2), pivotal for allergic and inflammatory response, hydrolyses phosphatidylcholine (PC) to lysophosphatidylcholine (LPC). In present study, the role of LPC in allergic airway disease manifestation was studied using mouse model. Balb/c mice were immunized using cockroach extract (CE) and LPC release was blocked by sPLA2 inhibitor. Airway hyperresponse (AHR), lung-histology, total and differential leukocyte count (TLC&DLC), Th2 type cytokines, sPLA2 activity and LPC levels in bronchoalveolar lavage fluid (BALF) were measured. Exogenous LPC was given to the mice with or without CE sensitization, to demonstrate its role in allergic airway disease manifestation. Anti-CD1d antibody was given to study the involvement of natural killer T (NKT) cells in LPC induced response. AHR, lung-inflammation, TLC, DLC, Th2 type cytokines, sPLA2 activity and LPC levels were increased on CE challenge. sPLA2 activity and LPC release was blocked by sPLA2-inhibitor, which decreased AHR, and inflammatory parameters. Exogenous LPC with or without CE sensitization increased above parameters. CE challenge or LPC exposure increased LY49C+TCRβ+ NKT cells in BALF and spleen, which was reduced by anti-CD1d antibody, accompanied with reduction in AHR and allergic airway inflammation parameters. Conclusively, LPC induces allergic airway disease manifestation and it does so probably via CD1d-restricted LY49C+TCRβ+ NKT cells. PMID:27282246

    Purpose of review The purpose is to review the important recent advances made in how innate immune cells, microbes, and the environment contribute to the expression of allergic disease, emphasizing the allergen-related signals that drive allergic responses. Recent findings The last few years have seen crucial advances in how innate immune cells such as innate lymphoid cells group 2 and airway epithelial cells and related molecular pathways through organismal proteinases and innate immune cytokines, such as thymic stromal lymphopoietin, IL-25, and IL-33 contribute to allergy and asthma. Simultaneously with these advances, important progress has been made in our understanding of how the environment, and especially pathogenic organisms, such as bacteria, viruses, helminths, and especially fungi derived from the natural and built environments, either promote or inhibit allergic inflammation and disease. Of specific interest are how lipopolysaccharide mediates its antiallergic effect through the ubiquitin modifying factor A20 and the antiallergic activity of both helminths and protozoa. Summary Innate immune cells and molecular pathways, often activated by allergen-derived proteinases acting on airway epithelium and macrophages as well as additional unknown factors, are essential to the expression of allergic inflammation and disease. These findings suggest numerous future research opportunities and new opportunities for therapeutic intervention in allergic disease. PMID:26658015

    The most common allergic diseases, and especially the respiratory disorders such as rhinitis and asthma, are closely related to the allergic inflammation elicited by the causative allergen. This makes inflammation the main target of anti-allergic therapies. Among the available treatments, allergen specific immunotherapy (AIT) has a patent effect on allergic inflammation, which persists also after its discontinuation, and is the only therapy able to modify the natural history of allergy. The traditional, subcutaneous route of administration was demonstrated to modify the allergen presentation by dendritic cells (DCs) that in turn correct the phenotype of allergen-specific T cells, switching from the Th2-type response, typical of allergic inflammation and characterized by the production of IL-4, IL-5, IL-13, IL-17, and IL-32 cytokines to a Th1-type response. This immune deviation is related to an increased IFN-gamma and IL-2 production as well as to the anergy of Th2 or to tolerance, the latter being related to the generation of allergen-specific T regulatory (Treg) cells, which produce cytokines such as IL-10 and TGF-beta. Anti-inflammatory mechanisms observed during sublingual AIT with high allergen doses proved to be similar to subcutaneous immunotherapy. Data obtained from biopsies clearly indicate that the pathophysiology of the oral mucosa, with particular importance for mucosal DCs, plays a crucial role in inducing tolerance to the administered allergen.

    We have investigated the exocytotic characteristics of neutrophils from allergic patients and healthy volunteers employing the whole cell membrane capacitance (Cm) measurement. The mean serum IgE level from allergic patients (423.75 +/- 12.75 IU/ml) determined by chemiluminescence immunoassay was much higher than that of healthy volunteers (28.47 +/- 16.68 IU/ml). Intracellular dialysis of buffered Ca2+ and GTPgammaS triggered biphasic exocytosis. The total capacitance increment displayed a steep dependence on pipette free Ca2+ concentration ([Ca2+]p), with maximal stimulation achieved at 10 microM. A significant decrease in the total capacitance increment was observed in the allergic group at [Ca2+]p >10 microM. Moreover, at submaximal stimulatory [Ca2+]p of 1 microM, the maximal rate of exocytosis in allergic patients (Vmax = 20.75 +/- 6.19 fF/s) was much faster than that of the healthy control group (Vmax = 7.97 +/- 2.49 fF/s). On the other hand, the Ca2+-independent exocytosis stimulated by GTPgammaS displayed no significant difference in either the total membrane capacitance increments or the maximal rate of exocytosis. The results suggest that hypersecretion of neutrophils in allergic diseases may involve the development of abnormal Ca2+-dependent exocytosis. PMID:15205559

    The response of peripheral neutrophils was studied in 16 patients with allergic asthma after challenge with birch/grass pollen allergen, in order to identify inflammatory markers associated with only the early asthmatic reaction and those associated with both early and late asthmatic reactions. The allergen challenge proceeded until the patients had an early asthmatic reaction with 100% increase in specific airway resistance. Bronchoconstriction after allergen challenge was monitored hourly over 9 h and finally after 18 h, by measurement of the forced expiratory volume in 1 s. Seven patients had a late reaction, defined as a decrease in forced expiratory volume in 1 s of more than 15%. Blood samples were taken before and 18 h after challenge. After allergen challenge (18 h) the blood concentration of neutrophils in patients with a late asthmatic reaction was 1.4 times higher than before challenge and there was a tendency for increased Fc gamma receptor-mediated chemiluminescence. Lewis X-antigen (CD 15), which is associated with endothelial adhesion and extravasation, significantly decreased at the same time. Neutrophils were incubated with the tetrapeptide arginine-glycine-aspartate-serine before and 18 h after allergen challenge. Both patient groups showed an increased Fc gamma receptor-mediated chemiluminescence and a decreased Fc gamma receptor membrane expression following allergen challenge, suggesting a preactivation. In conclusion, patients with a dual asthmatic reaction show a sustained primed inflammatory response and primed neutrophils compared with patients with only an early reaction when measured after the decline of clinical symptoms provoked by allergen challenge.

    The gastrointestinal (GI) tract microbiota is required for optimal digestion of foods, for the development of resistance against pathogens (termed colonization resistance), for the development of mucosa-associated lymphoid tissue, and for local as well as systemic immune homeostasis. Certain constituents of the GI tract microbiota are widely recognized as critical regulators and modulators of their host's immune response. These include bacterial members of the microbiota as well as parasitic nematodes. Immune regulation by immunomodulatory members of the GI microbiota primarily serves to subvert host antimicrobial immune defenses and promote persistent colonization, but as a side effect may prevent or suppress immunological disorders resulting from inappropriate responses to harmless antigens, such as allergy, colitis or autoimmunity. Many of the best understood GI-resident immunomodulatory species have co-evolved with their mammalian hosts for tens of thousands of years and masterfully manipulate host immune responses. In this review, we discuss the epidemiological evidence for the role of the GI tract microbiota as a whole, and of specific members, in protection against allergic and other immunological disorders. We then focus on the mechanistic basis of microbial immunomodulation, which is presented using several well-understood paradigmatic examples, that is, helminths, Helicobacter pylori, Bifidobacteria and Lactobacilli. In a final chapter, we highlight past and ongoing attempts at harnessing the immunomodulatory properties of GI microbiota species and their secreted products for intervention studies and describe the promises and limitations of these experimental approaches. The effects of pro- and prebiotics, bacterial lysates, as well as of fecal microbiota transplantation are presented and compared. PMID:27028536

  2. Allergic contact sensitizing chemicals as environmental carcinogens.

    1997-01-01

    Chemicals that were bioassayed by the National Toxicology Program (NTP) and that also produce allergic dermatitis (ACD) in humans were evaluated for their tumorigenic characteristics. The impetus for the study was that most contact sensitizers, i.e., those that produce ACD, and genotoxic carcinogens are chemically similar in that they are electrophilic, thereby producing adducts on macromolecules including protein and DNA. This similarity in chemical behavior suggests that many contact sensitizers might be environmental carcinogens. All of the published NTP bioassays by early 1996 that had both genotoxicity and carcinogenicity studies were included in this analysis. The NTP chemicals had been chosen for bioassay without regard to their ability to produce ACD. Of the 209 chemicals that were bioassayed, there were 36 (17%) that were known to be human contact sensitizers; about half of these were positive on tumor bioassays. The contact sensitizers differed from the NTP sample as a whole by having a proportionately larger number of nongenotoxic chemicals by the Ames Salmonella assay, presumably because more of them were selected on the basis of widespread usage rather than structural resemblance to known carcinogens. Compared to the nongenotoxic chemicals, the genotoxics were stronger carcinogens in that they had a higher incidence of positive tumor bioassays, with twice the number of organs in which tumors were induced. The nongenotoxic chemicals had a preference for tumor induction in parenchymal tissues in contrast to epithelial tissues. The contact sensitizers showed essentially the same characteristics as the whole NTP sample when stratified according to genotoxicity. Judging by the chemicals that were chosen primarily for their widespread use rather than for their structural resemblance to carcinogens, the addition of a test for contact sensitization to the Ames test as a screening tool would increase the tumorigenic detection efficiency by about 40% because of

    Allergic contact dermatitis due to citrus fruits is rare, but has been reported in cooks and bartenders. We report an interesting case of a bartender with hand dermatitis who had an allergic contact sensitivity to lime peel, fragrance mix I, and fragrance mix II. Most reported cases of citrus peel allergy are due to d-limonene, which makes up the majority of the peel oil. However, our patient had an allergic reaction to geraniol, which is a minor component of the peel oil and is present in fragrance mix I. It is important to consider a contact sensitivity to citrus in patients who have positive reactions to fragrance mix I and II and who are occupationally exposed to citrus fruits. An initial positive reaction to fragrance mixes should prompt further testing to citrus in these individuals. PMID:20646673

    Serum albumin (SA) constitutes an intriguing puzzle that is involved in allergic sensitizations from different sources and induces different clinical manifestations. In this article, we describe the role of sensitization to SAs in inducing allergic diseases and the complex interactions and cross-reactivity between SA resulting from its presence in various mammalian tissues and fluids. SAs alone are an uncommon cause of allergic sensitization in airways, but these allergenic proteins likely play a significant role as cross-reacting allergens in individuals sensitized to several types of animal dander. SAs are a minor allergen in milk but a major allergen in meats. Recently, bovine SA has been added to the culture medium of spermatozoids used for artificial insemination. As a consequence, some case reports have shown that bovine SA may be a causative agent in severe anaphylaxis after standard intrauterine insemination or in vitro fertilization. PMID:21809117

    Summary Allergic asthma is a chronic inflammatory condition of the lung characterized by reversible airway obstruction, high serum immunoglobulin (Ig) E levels, and chronic airway inflammation. A number of cells including mast cells, T-cells, macrophages and dendritic cells play a role in the pathogenesis of the disease. Janus Kinase (JAK) −3, a nonreceptor protein tyrosine kinase, traditionally known to mediate cytokine signaling, also regulates functional responses of these cells. In this review the role of JAK-3 in regulating various pathogenic processes in allergic asthma is discussed. We propose that targeting JAK-3 is a rationale approach to control the inflammatory responses of multiple cell types responsible for the pathogenesis of allergic asthma. PMID:20430118

    Allergies are a widespread group of diseases of civilization and most patients are still undertreated. Since histamine is considered to be the most important mediator in allergies such as allergic rhinitis and urticaria, the most commonly used drugs to treat these disorders are antihistamines acting on the histamine 1 (H1) receptor. The currently available antihistamines, however, have significant differences in their effects and safety profiles. Furthermore, the Allergic Rhinitis and its Impact on Asthma initiative calls for additional desirable properties of antihistamines. Here, we review the profile of rupatadine, a new dual platelet-activating factor and H1-receptor antagonist that fulfils these criteria and therefore offers an excellent option for the treatment of allergic diseases.

    Allergic rhinitis (AR) is a common respiratory disease, and its prevalence is increasing all over the world, both in adults and in children. Patients experience symptoms that may negatively impact on physical, social and psychological well-being. Hence, if left untreated, allergic rhinitis may significantly affect quality of life. Under current guidelines, intranasal corticosteroids are considered the most effective drugs and they are recommended as first-line therapy. Among the several corticosteroid intranasal sprays available, beclomethasone dipropionate is one of the most prescribed. Recently, new intranasal hydrofluoroalkane-propelled formulations with little or no impact on the ozone layer have been developed for the treatment of AR. The use of these devices might improve patients' adherence to treatment, avoiding some of the most common side effects associated with aqueous formulations. This review provides the most recent evidence for the efficacy and safety of beclomethasone dipropionate hydrofluoroalkane nasal aerosol in the treatment of allergic rhinitis. PMID:26558604

    After more than a decade of use, topical minoxidil solution has proven to be a safe and effective treatment for androgenetic alopecia. However, some patients present with complaints of pruritus and scaling of the scalp. The most common causes of these symptoms include irritant contact dermatitis, allergic contact dermatitis, or an exacerbation of seborrheic dermatitis. Patients suffering from allergic contact dermatitis may benefit from patch testing to determine the causative allergen. Among the patients we patch tested, propylene glycol was found to be the contactant in a majority of cases, not the minoxidil itself. Many of these patients may be candidates for treatment with alternative formulations using other solvents, such as butylene glycol, polysorbate, or glycerol. Although predictive, patch testing results do not ensure that the compounded preparations will be tolerated. Unfortunately, patients found to be allergic to minoxidil are no longer candidates for topical treatment of their alopecia with any preparations of minoxidil. PMID:11807448

    The involvement of autonomic imbalance has been reported in the pathogenesis of hypersensitivity reactions. Allergic diseases are more frequent in children and some of predisposing factors may be changed according to the increasing age, but the involvement of autonomic imbalance has not been investigated in pediatric population. In this cross-sectional, case-control study, we evaluated the autonomic system by measuring heart rate variability (HRV) in pediatric patients with allergic rhinitis. Thirty-five pediatric patients with allergic rhinitis and 36 healthy children (mean age 11 +/- 2.7, and 12 +/- 3 years, respectively) were enrolled in the study. Age and gender were not different between the groups. The diagnosis of allergic rhinitis was based on the history, symptoms, and skin prick tests. Participants with acute infection, nasal polyposis, bronchial asthma, and any other medical problems, assessed by history, physical examination and routine laboratory tests, were excluded. Twenty-four hour ambulatory electrocardiographic recordings were obtained, and the time domain and frequency domain indices of HRV were analyzed. We found significant increase in calculated HRV variables in children with allergic rhinitis compared to controls, which reflect parasympathetic tones, such as number of R-R intervals exceeding 50 ms, root mean square of successive differences between normal sinus R-R intervals, the percentage of difference between adjacent normal R-R intervals, and high frequency. These results indicate that HRV is increased, which implies sympathetic withdrawal and parasympathetic predominance. We propose that autonomic imbalance may be involved in the pathophysiology of allergic rhinitis in pediatric patients. PMID:19851046

    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

    Although allergic rhinitis is considered a raising medical problem in many countries it is often undertreated. The reasons for this phenomenon are not completely clear.The aim of this study is to evaluate factors associated with allergic rhinitis under-/no treatment.A sample of 518 allergic rhinitis patients recruited by their primary care physicians, as a part of the ARGA study, were invited to fill in a specific questionnaire regarding rhinitis symptoms, treatment, and rhinitis-related work/social disability. Chi-square test and logistic regression were performed to assess risk factors for allergic rhinitis under-/no treatment.Over one out of four patients had no treatment despite the symptoms and 13.5% were inadequately treated. Participants with asthma (OR 0.47, 95% CI 0.30-0.75) and conjunctivitis (0.44, 95% CI 0.27-0.71) were at lower risk of allergic rhinitis under-/no treatment: in asthmatics this reduction was related mainly to the concomitant asthma treatment (OR 0.19, 95% CI 0.10-0.37).Asthmatics with under-/not treated rhinitis had the highest prevalence of rhinitis-related quality of life impairment.Under-/no treatment for allergic rhinitis is still rather frequent despite the relevance of this disease. The simultaneous presence of asthma and an anti-asthmatic therapy are able to influence positively the treatment. Targeted interventions toward a better characterization and a tight follow-up of rhinitis patient without asthma are needed. PMID:26680255

    Allergic rhinitis (AR) is a chronic inflammatory disease of rhino-ocular mucosa, affecting up to 40% of population worldwide. Chinese herbal medicines and Acupuncture, adopted thousands of years in China, has good effect on allergic rhinitis. This study evaluates the effects of Moxibustion with Chinese herbal in treating patients with allergic rhinitis over a 1-year follow-up. A randomized controlled trial was conducted in a sample of 355 participants recruited from Guangdong general hospital of China. After baseline measurements, participants were randomly assigned to treatment-group or control group. Treatment group received Moxibustion with Chinese herbal. Control group received Loratadine. The main outcomes, including symptom severity and quality of life were measured using the Allergic Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ). Both moxibustion with Chinese herbal and Loratadine improve nose symptoms such as stuffy/blocked, sneezing, runny nose, itchy nose, sore nose and post-nasal drip in patients with AR. Symptoms fatigue, loss of taste, afraid of cold/wind and cold limb were improved significantly in moxibustion with Chinese herbal group. The mean quality of life scores decreased in both groups after treatment. Compare to control group, moxibustion with Chinese herbal is more effective than Loratadine in improving the quality of life in patients with AR. The results show moxibustion with Chinese herbal was effective to reduce symptoms and enhance quality of life in patients with allergic rhinitis. It is a simple, convenient and economic therapy for patients with AR. Further controlled trials of its effects in patients with allergic rhinitis are recommended. PMID:26629174

    Non-infectious granulomatous diseases of the skin are a broad group of distinct reactive inflammatory conditions that share important similarities. As a group, they are relatively difficult to diagnose and distinguish both clinically as well as histologically. Many of these disorders have significant associations with systemic diseases that impact the patient's overall prognosis. In this update, we offer a discussion of emerging concepts and controversies in this field, as presented through evidence-based answers to seven important clinical questions regarding palisading and epithelioid granulomata. These questions offer an opportunity to review ten non-infectious granulomatous conditions that have implications for systemic disease: granuloma annulare, annular elastolytic giant cell granuloma, necrobiosis lipoidica, methotrexate-induced accelerated rheumatoid nodulosis, necrobiotic xanthogranuloma, interstitial granulomatous dermatitis, interstitial granulomatous drug reaction, palisaded neutrophilic granulomatous dermatitis, sarcoidosis, and metastatic Crohn disease. Recent clinical, epidemiologic, and laboratory studies have shed some light on these diseases, the association of these conditions with systemic disorders, and their overall prognoses. PMID:20184390

    Chronic granulomatous disease (CGD) can be cured by allogeneic hemopoietic stem cell transplantation (HSCT). Complications include graft failure, graft-versus-host disease (GVHD), infection, and transplant-related mortality; therefore, reduced-intensity conditioning regimens are being used to improve outcomes. In this retrospective study, the aim was to determine the outcome of treosulfan-based conditioning in HSCT for pediatric patients with CGD. The following data were collected: risk features pre-HSCT, additional conditioning agents, donor type and stem cell source, toxicity, engraftment, GVHD, chimerism, viral reactivation, post-HSCT complications, length of follow-up, and outcome. Seventy patients (median age, 107 months; interquartile range [IQR], 46-232 months) from 16 centers worldwide were transplanted between 2006 and 2015. Ninety-one percent had high-risk features. Fifty-seven HLA-matched donors, 12 HLA-mismatched donors, and 1 CD3(+)TCR αβ/CD19 depleted parental haploidentical transplants were performed. No major toxicity was reported. Median times to neutrophil and platelet engraftment were 17 (IQR, 15-35) and 16 (IQR, 13-50) days. At a median follow-up of 34 months (IQR, 13-102 months), the overall survival was 91.4%, and event-free survival was 81.4%. The cumulative incidence of acute grade III-IV GVHD was 12%. Nine patients developed chronic GVHD. When split cell chimerism was available, 95% or more myeloid donor chimerism was documented in 80% of surviving patients. Secondary graft failure occurred in 12% of patients. Treosulfan-containing conditioning regimens can be used safely in HSCT for children with CGD and high-risk clinical features, achieving excellent survival with high myeloid chimerism. Further studies are needed to compare with other regimens and evaluate the long-term outcome, particularly on fertility. PMID:27216217

    Background Granulomatous amoebic encephalitis due to Acanthamoeba is often a fatal human disease. However, the pathogenesis and pathophysiology of Acanthamoeba encephalitis remain unclear. In this study, the role of extracellular Acanthamoeba proteases in central nervous system pathogenesis and pathophysiology was examined. Results Using an encephalitis isolate belonging to T1 genotype, we observed two major proteases with approximate molecular weights of 150 KD and 130 KD on SDS-PAGE gels using gelatin as substrate. The 130 KD protease was inhibited with phenylmethylsulfonyl fluoride (PMSF) suggesting that it is a serine protease, while the 150 KD protease was inhibited with 1, 10-phenanthroline suggesting that it is a metalloprotease. Both proteases exhibited maximal activity at neutral pH and over a range of temperatures, indicating their physiological relevance. These proteases degrade extracellular matrix (ECM), which provide structural and functional support to the brain tissue, as shown by the degradation of collagen I and III (major components of collagenous ECM), elastin (elastic fibrils of ECM), plasminogen (involved in proteolytic degradation of ECM), as well as casein and haemoglobin. The proteases were purified partially using ion-exchange chromatography and their effects were tested in an in vitro model of the blood-brain barrier using human brain microvascular endothelial cells (HBMEC). Neither the serine nor the metalloprotease exhibited HBMEC cytotoxicity. However, the serine protease exhibited HBMEC monolayer disruptions (trypsin-like) suggesting a role in blood-brain barrier perturbations. Conclusion Overall, these data suggest that Acanthamoeba proteases digest ECM, which may play crucial role(s) in invasion of the brain tissue by amoebae. PMID:16672059

    Introduction Infectious Granulomatous Dermatoses (IGDS) have various aetiological factors with a considerable overlap in the histopathological and clinical features, thus posing a diagnostic dilemma for dermatologists and pathologists. Aim We aimed at determining the histopathological profile of IGDS correlating it with clinical features with an attempt to find the aetiology. Materials and Methods In a cross-sectional study conducted in a tertiary referral center of Mumbai over two years, out of 1872 skin biopsies received, 239 histopathologically diagnosed cases of IGDS were studied for histopathological features of granuloma. A clinico-histopathological correlation was attempted. Chi-square test was used for comparison of proportions of different groups. Results Leprosy (211 cases) and tuberculosis (28 cases) were the commonest histopathologically diagnosed IGDS. Leprosy spectrum included BT (30.33% cases), followed by TT (21.32%), BL and LL and 21.79% cases of lepra reactions. Skin TB biopsies on histopathology showed lupus vulgaris (53.85% cases), scrofuloderma (15.38%), TBVC and papulonecrotic tuberculid (11.54% each). In leprosy maximum clinico-pathological agreement was seen at tuberculoid pole (TT 72.7% and BT 56.6%). Among tuberculosis cases, scrofuloderma (100%) and lupus vulgaris (53.8%) showed maximum agreement. Conclusion Leprosy and skin TB are the commonest IGDS in Mumbai region though difficult to diagnose and subcategorize with certainty during initial stages. Histopathology plays the important role to elucidate the dilemma. This being a single center study, more such studies with a larger sample size are recommended to get more elaborate data and regional prevalence of these IGDS for a better overall approach to prevention, treatment and control.

    Chronic granulomatous disease (CGD) is a rare hereditary disorder that is characterized by a greatly increased susceptibility to life-threatening bacterial and fungal infections. CGD is caused by mutations in any one of the genes encoding subunits of phagocyte NADPH oxidase. X-linked CGD, more than half of all CGD cases, is caused by mutations in CYBB gene encoding gp91-phox subunit. We identified the mutations in the CYBB gene of 29 Korean patients with X-linked CGD from 26 unrelated families. Twenty-three mutations were identified: five splice site mutations (c.45 + 1G > C, c.141 + 5G > A, c.897 + 2T > C c.1461 + 1G > T, c.1586 + 2T > A), four frameshift mutations (c.27dupG, [c.737A > C; c.742delA], c.742dupA, c.1636 del C), seven non-sense mutations (c217C > T, c.469C > T, c.676C > T, c.868C > T, c.1222G > T, c.1272G > A, c.1281T > A), five missense mutations (c.164 C > A, c.422T > C, c.665 A > G, c.1012C > T, c.1461G > T) and two gross deletions. Eight out of 23 mutations identified in this study are novel mutations: two splice mutations(c.897 + 2T > C, c.1586 + 2T > A), two frame shift mutations ([c.737A > C; c.742delA], c.1636 del C), two nonsense mutations (c.1222G > T, c.1281T > A), one missense mutation (c.1461G > T), one gross deletion (c.1667_1629 del.). Our results confirmed that mutations of CYBB gene in the X-CGD are very heterogeneous and not show the peculiarity of the ethnic group. PMID:24999735

    INTRODUCTION Granulomatous cervicofacial lymphadenitis (GCL) is not uncommon in children. Nontuberculous mycobacteria (NTM) seem to be the predominant cause. We sought to study the clinical and microbiological profile of patients with GCL, and identify features that may impact outcome. METHODS Children aged < 16 years who presented to KK Women’s and Children’s Hospital, Singapore, between January 1998 and December 2006, and who had GCL were identified from laboratory records. Clinical and laboratory data was collected and analysed for risk factors for patients with positive lymph node cultures, and for patients with and without recurrence after treatment. RESULTS In all, 60 children were identified, with a median age of 56 (interquartile range [IQR] 34–101) months. Median duration of symptoms before presentation was 5 (IQR 4­–8) weeks. The majority presented with single (73.3%) or unilateral (96.7%) lymphadenopathy, located in the submandibular, preauricular/parotid or infra-/post-auricular region (76.7%). Out of 51 patients, 26 (51.0%) had a tuberculin skin test reading of ≥ 10 mm. Out of 52 patients, 10 (19.2%) had positive mycobacterial cultures, which included seven isolates of NTM. Out of 34 cases, tuberculous polymerase chain reaction was positive in 11 (32.4%). With regard to recurrence after initial treatment, age < 5 years at presentation was found to be a predictor for recurrence (p = 0.008), while initial complete excision of affected nodes predicted no recurrence (p = 0.003). CONCLUSION In our study, younger age was noted to be associated with a higher chance of recurrence, while complete excision of the involved node at initial presentation predicted non-recurrence.

    Background Lung cancer and tuberculosis (TB) are two major public health problems. They can coexist or appear sequentially. In patients with TB, lung cancer risk is increased. However, vice versa is not crystal clear. In this study, we aimed to determine the development of TB in patients with resectabled non-small cell lung cancer (NSCLC) in a 2-year postoperative follow-up period. Material/Methods We conducted a retrospective cohort study at three university hospitals. Patients who had NSCLC surgery between 2009 and 2013 were included and patient records were reviewed for the presence of necrotizing granulomatous inflammation (NGI) in resected specimens. Demographic properties, tumor type, stage, location, type of surgery, tuberculosis history, and thorax CT findings were recorded. We searched for the development of tuberculosis within a 2-year period after surgery. Results A total of 1027 patient cases were reviewed, of which 48 patients had NGI. The median age was 63 years. The most common type of cancer was squamous carcinoma; and lobectomy was the preferred operation (70.8%). Cancer involvement most commonly included the right lung (61.8%) and upper lobes (47,9%). Only 11 patients had anti-TB treatment postoperatively, which was based on radiological findings. Prior tuberculosis or anti-TB history, type, stage or localization of cancer, and adjuvant/neoadjuvant therapy were not found to be related to TB treatment. None of the study population had TB during the two-year follow-up period. Treatment decisions appeared mostly related to physician experience. There was no difference in the risk of developing TB between patients with or without treatment. This finding may change the management of our patients. Conclusions Every NGI discovered in NSCLC resected material does not always require anti-TB treatment. PMID:27064420

    Allergic contact dermatitis from the topical use of essential oils is not widely recognized as an occupational hazard. Four cases of allergic contact dermatitis to essential oils occurring in three aromatherapists and one chemist with a particular interest in aromatherapy are described. All presented with predominantly hand dermatitis and demonstrated sensitization to multiple essential oils. One patient developed a recurrence of cutaneous symptoms following ingestion of lemongrass tea. Workers within this industry should be aware of the sensitization potential of these products and the risk of limiting their ability to continue employment. PMID:12121401

    Human exposure to fungi results in a wide range of health outcomes, from invasive disease or allergy to immune tolerance. Inhaled fungi contact airway epithelial cells as an early event, and this host:fungal interaction can shape the eventual immunological outcome. Emerging evidence points to exposure to fungal cell wall carbohydrates in the development of allergic airway disease. Herein, we describe determinants of fungal allergenicity, and review the responses of airway epithelial cells to fungal carbohydrates. A greater understanding of the recognition of and response to fungal carbohydrates by airway epithelial cells may lead to the development of targeted therapies that ameliorate allergic airway disease.

    Allergic rhinitis (AR) results from a complex allergen-driven mucosal inflammation in the nasal cavity. Current guideline-based therapy for allergic rhinitis include oral and nasal antihistamines, topical and systemic glucocorticoids, decongestants, antimuscarinic agents, mast cell stabilizing drugs, leukotriene-receptor antagonists, and others. In spite of guideline recommendations, most patients are using multiple therapies in an attempt to achieve symptom control. Therefore, more effective therapies for the management of AR are clearly required. Recently, a novel fixed dose combination containing azelastine and fluticasone propionate has successfully been introduced. At present, it represents the only meaningful topical drug combination. Perhaps, it will be followed by others. PMID:24974572

    Thymic stromal lymphopoietin (TSLP) is an interleukin (IL) 7–like cytokine that triggers dendritic cell–mediated T helper (Th)2 inflammatory responses. TSLP is highly expressed by keratinocytes in skin lesions of patients with atopic dermatitis and is associated with dendritic cell activation in situ, suggesting that TSLP might be a master switch for allergic inflammation at the epithelial cell–dendritic cell interface. New reports now establish a direct link between TSLP expression and the pathogenesis of atopic dermatitis and asthma in vivo, and begin to reveal the molecular mechanisms underlying TSLP-induced allergic inflammation.

    Asthma is described as a chronic inflammatory disorder of the conducting airways. It is characterized by reversible airway obstruction, eosinophil and Th2 infiltration, airway hyper-responsiveness and airway remodeling. Our findings to date have largely been dependent on work done using animal models, which have been instrumental in broadening our understanding of the mechanism of the disease. However, using animals to model a uniquely human disease is not without its drawbacks. This review aims to examine some of the key mediators and cells of allergic asthma learned from animal models and shed some light on emerging mediators in the pathogenesis allergic airway inflammation in acute and chronic asthma.

    Background Texture analysis is a computer tool that enables quantification of gray-level patterns, pixel interrelationships, and spectral properties of an image. It can enhance visual methods of image analysis. Primary lung cancer and granulomatous nodules have identical CT imaging features. The purpose of this study was to assess the sensitivity and specificity of CT texture analysis in differentiating lung cancer and granulomas. Methods This retrospective study evaluated 55 patients with primary lung cancer and granulomatous nodules who had contrast-enhanced (CE) and/or non-contrast-enhanced (NCE) CT within 3 months of biopsy. Textural features were extracted from 61 nodules. Mann-Whitney U tests were used to compare values for nodules. Receiver operating characteristic (ROC) curves were constructed and the area under the curve (AUC) calculated with histopathology as outcome. Combinations of features were entered as predictors in logistic regression models and optimal threshold criteria were used to estimate sensitivity and specificity. Results The model generated by sum of squares, sum difference, and sum entropy features for NCE CT yielded 88% sensitivity and 92% specificity (AUC =0.90±0.06, P<0.0001). For nodules with fluorodeoxyglucose positron emission tomography (FDG-PET)/CT, sensitivity for detection of lung cancer was 79.2% (CI: 57.8–92.9%), specificity was 38.5% (CI: 13.9–68.4%) and accuracy was 64.8%. Conclusions Quantitative CT texture analysis has the potential to differentiate primary lung cancer and granulomatous lesions. PMID:26981450

    Breast milk contains several components that provide specific immunity and affect the maturation of the infant's immune system. The aim of this study was to analyze the effects of breast milk, on mitogen- and allergen-induced cytokine production from cord blood mononuclear cells (CBMC), and if those effects differ between allergic and non-allergic mothers. The cells were incubated for 96 h with phytohemagglutinin (PHA), ovalbumin or cat dander in the presence of various dilutions of colostrum. Colostrum inhibited both mitogen- and cat-induced IFN-gamma and mitogen-induced interleukin-4 (IL-4) production. The inhibition on IFN-gamma production was to some extent caused by TGF-beta, as the effect was modified when an anti-TGF-beta antibody was added to the cultures. In contrast, colostrum enhanced allergen-induced production of the Th2-like cytokines IL-5 and IL-13, and this was accompanied with increased production of IL-10. No differences were found between allergic and non-allergic mothers. The inhibitory effect of breast milk on IFN-gamma production, which was partly due to the high levels of TGF-beta, together with the enhancing effect on IL-10 secretion, confirm that breast milk is anti-inflammatory. Although the production of IL-5 and IL-13 was enhanced by colostrum, this was accompanied with an increased production of IL-10. Together with the high levels of TGF-beta in breast milk and inhibitory effect of colostrum on IL-4 production, this suggests a possible mechanism whereby breast-feeding may protect against the development of allergy. Despite differences in the composition of breast milk between allergic and non-allergic mothers, the effects of breast milk on cytokine production from CBMC were independent of the atopic status of the mothers.

    Chronic granulomatous disease (CGD) is a primary immunodeficiency disease characterized by recurrent life-threatening bacterial and fungal infections with granuloma formation. Species of the genus Fusarium are opportunistic environmental microorganisms that are rarely pathogenic in humans. We report here the first case of X-linked CGD complicated with epidural abscess caused by Fusarium falciforme infection. The abscesses extended along the dura mater for >7 years and finally resulted in fatal meningitis and cervical myelitis. Early intervention with hematopoietic stem cell transplantation should be considered, especially in patients with severe CGD, before the development of serious infectious complication. PMID:25711271

    Although macrophage activation syndrome (MAS) develops in some patients with chronic granulomatous disease (CGD), all of the reported cases have been associated with pathogenic microbial infections. We report a 2-year-old boy with CGD-associated colitis who suffered from MAS without any clinical signs of a microbial infection. He was treated with 1 course of methylprednisolone pulse therapy and the clinical symptoms improved; however, the colitis was difficult to control even with immunosuppressive drugs, and he eventually required hematopoietic stem cell transplantation 1 year after the onset of MAS. It is likely that MAS develops in patients with CGD colitis independent of microbial infections. PMID:23652865

    Pulmonary manifestations associated with food allergy are rich in variety. We report the first case of food-induced granulomatous interstitial pneumonia mimicking hypersensitivity pneumonitis (HP). A 77-year-old woman with respiratory symptoms was referred to our hospital. We performed a surgical lung biopsy, which showed the features of granulomatous interstitial pneumonia. Her clinical history resembled those observed in HP. However, avoidance of exposure to the causative antigens did not improve her symptoms. Moreover, the patient had some features inconsistent with HP, such as elevated serum IgE levels, blood eosinophilia, intrathoracic lymphadenopathies and pleural effusion. Therefore, we pursued another extrinsic non-inhaled antigen as the cause of pulmonary involvements. We noted that she had been eating homemade rice bran pickles, and pulmonary involvements were induced by an ingestion challenge test. We suggest that granulomatous interstitial pneumonia may be a rare subtype of the pulmonary manifestations associated with food allergy. PMID:25858927

    Knowing the incidence of allergic diseases and their relationship with allergens is a crucial requirement for therapeutic judgment. We present our experience on the incidence, clinical features and allergens of the allergic diseases detected by multiple allergosorbent chemiluminescent assay (MAST-CLA) in children from 1997 to 1999 at the Taipei Veterans General Hospital. The incidence of bronchial asthma, allergic rhinitis and atopic dermatitis are significantly different when stratified by age groups. Among the enrolled 2008 patients, 980 (48.8%) patients have positive MAST-CLA results. Of these, 562 (57.3%) are male and 418 (42.7%) are female. A significant increase among patients with positive allergens is also found when stratified by age group. Inhalant allergen is the major allergen detected in our patients. House dust mites Dermatophagoides pteronyssinus (Dp) and Dermatophagoides farinae (Df), cockroaches, feathers, and dog dander show the highest incidence in the 7- to 12-year-old group. In the fungal group, Aspergillus and Penicillium also show a significant difference in the incidence among different age groups. Pollen allergens, on a whole, show significant difference in incidence among different age groups. The food allergen group shows variable significant difference in incidence. Crab, milk, and egg white show the highest significant incidence in the 2- to 6-year-old group. These results suggest that the incidence of allergens detected in allergic diseases varies among different age groups. PMID:11269366

    The so-called local allergic rhinitis (LAR) has been proposed as a phenotype of rhinitis with Th2-driven prominent local allergic inflammation, nasal synthesis of specific IgE and a positive response to a nasal allergen provocation test, in the absence of 'systemic' atopy (negative skin prick test and serum allergen-specific IgE antibodies). To date, available data on LAR are mostly focused on adults. The purpose of this 'Rostrum' was to critically discuss data and implications of the 'LAR concept' in paediatrics. In the natural history of rhinitis due to IgE-mediated reactions triggered by exposure to allergens, a 'LAR' can be either the initial, transient stage of classical allergic rhinitis or a stable phenotype never evolving to 'systemic' IgE sensitization. Given the present difficulties in performing routinely nasal allergen provocation test in children, the development of sensitive and specific tests to detect IgE in the child's nasal secretions is a research priority. We suggest also the hypothetical role of allergen immunoprophylaxis or immunotherapy in LAR. Last, the term 'local allergic rhinitis' may be inappropriate, as rhinitis is always 'local', while IgE sensitization can be either 'local' or 'systemic'. PMID:27098888

    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.

    2009-01-01

    The intestinal microbiota plays an important role in immune development and may play a role in the development of allergic disorders. Manipulation of the intestinal microbiota may therefore offer an approach to the prevention or treatment of allergic diseases. Probiotics and prebiotics, used alone or together (synbiotics), can influence the intestinal microbiota and modulate immune responses in vitro and in vivo. Clinical studies suggest a potential role for selected probiotics (alone or in combination with prebiotics) in the prevention of atopic eczema. A prenatal component of treatment appears important for beneficial effects. Effects are dependent upon the specific bacteria and characteristics of the study population. One study reported beneficial effects for prebiotics in the prevention of eczema in high-risk infants, however, further studies are required to confirm this. The use of probiotics in the treatment of allergic disease is less promising. A Cochrane meta-analysis concluded that probiotics are not effective for the treatment of atopic dermatitis. Probiotic effects in the treatment of asthma and allergic rhinitis are conflicting. Probiotics, prebiotics and synbiotics offer potential treatments for the prevention of atopic eczema; however, there is currently insufficient evidence to recommend their use in clinical practice. Studies to clarify the optimal dose, bacterial species/strains, whether there is added benefit with synbiotics, the optimal timing for intervention, and the patient populations who would benefit most from such therapies are warranted.

    Platelet activation is associated with multiple immune responses and the pathogenesis of various immune-related diseases. However, the exact role and the underlying mechanism of platelets in the progression of allergic asthma remain largely unclear. In this study, we demonstrate that during antigen sensitization, platelets can be activated by ovalbumin (OVA) aerosol via the upregulation of CD154 (CD40L) expression. Platelet transfer promoted allergic asthma progression by inducing more severe leukocyte infiltration and lung inflammation, elevated IgE production and strengthened T helper 2 (Th2) responses in asthma-induced mice. Accordingly, platelet depletion compromised allergic asthma progression. Cd154-deficient platelets failed to promote asthma development, indicating the requirement of CD154 for platelets to promote asthma progression. The mechanistic study showed that platelets inhibited the induction of Foxp3(+) regulatory T cells both in vivo and in vitro at least partially through CD154, providing an explanation for the increase of Th2 responses by platelet transfer. Our study reveals the previously unknown role of platelet CD154 in the promotion of asthma progression by polarizing Th2 responses and inhibiting regulatory T-cell generation and thus provides a potential clue for allergic disease interventions.

    Allergic asthma is characterized by bronchial hyperresponsiveness, a defective barrier function, and eosinophilic lower airway inflammation in response to allergens. The inflammation is dominated by Th2 cells and IgE molecules and supplemented with Th17 cells in severe asthma. In contrast, in healthy individuals, allergen-specific IgA and IgG4 molecules are found but no IgE, and their T cells fail to proliferate in response to allergens, probably because of the development of regulatory processes that actively suppress responses to allergens. The presence of allergen-specific secretory IgA has drawn little attention so far, although a few epidemiological studies point at a reverse association between IgA levels and the incidence of allergic airway disease. This review highlights the latest literature on the role of mucosal IgA in protection against allergic airway disease, the mechanisms described to induce secretory IgA, and the role of (mucosal) dendritic cells in this process. Finally, we discuss how this information can be used to translate into the development of new therapies for allergic diseases based on, or supplemented with, IgA boosting strategies. PMID:23690823

    BACKGROUND: The increasing prevalence of allergic diseases and atopy is affected by sex, age and lifestyle factors. Obesity and excess weight are reported to be potential risk factors for atopy and specifically for asthma symptoms in children and adults. OBJECTIVE: To assess the relation between body mass index (BMI) and allergic diseases in patients of both genders, as well as association of BMI with atopy in healthy subjects. METHODS: BMI (kg/m2), skin-prick test and total serum immunoglobulin E levels were assessed in 139 subjects: 109 were patients with allergic diseases (M to F ratio was 51:58) and 30 were healthy controls (M to F ratio was 6:24). RESULTS: The study population was grouped into asthma, asthmarhinitis, rhinitis, Urticaria oreczema and controls by BMI and sex. Females with the highest BMI were in asthma and urticaria/eczema group. Males with the highest BMI were in asthmarhinitis and urticariaeczema group. High BMI was associated with atopy in both genders of healthy controls. High levels of total IgE were in male allergic patients. CONCLUSION: High BMI was associated with asthma in females, urticaria/eczema in both genders and atopy in both genders of healthy controls. Higher levels of total IgE were concluded in male patients.

    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.

    Allergen-specific immunotherapy (AIT) is the only curative way that can change the immunologic response to allergens and thus can modify the natural progression of allergic diseases. There are some important criteria which contributes significantly on efficacy of AIT, such as the allergen extract used for treatment, the dose and protocol, patient selection in addition to the severity and control of asthma. The initiation of AIT in allergic asthma should be considered in intermittent, mild and moderate cases which coexisting with other allergic diseases such as allergic rhinitis, and in case of unacceptable adverse effects of medications. Two important impact of AIT; steroid sparing effect and preventing from progression to asthma should be taken into account in pediatric asthma when making a decision on starting of AIT. Uncontrolled asthma remains a significant risk factor for adverse events and asthma should be controlled both before and during administration of AIT. The evidence concerning the efficacy of subcutaneous (SCIT) and sublingual immunotherapy (SLIT) for treatment of pediatric asthma suggested that SCIT decreases asthma symptoms and medication scores, whereas SLIT can ameliorate asthma symptoms. Although the effectiveness of SCIT has been shown for both seasonal and perennial allergens, the data for SLIT is less convincing for perennial allergies in pediatric asthma. PMID:27489785

    Allergic diseases comprise a genetically heterogeneous group of chronic, immunomediated diseases. It has been clearly reported that the prevalence of these diseases has been on the rise for the last few decades, but at different rates, in various areas of the world. This paper discusses the epidemiology of allergic diseases among children and their negative impact on affected patients, their families, and societies. These effects include the adverse effects on quality of life and economic costs. Medical interest has shifted from tertiary or secondary prevention to primary prevention of these chronic diseases among high-risk infants in early life. Being simple, practical, and cost-effective are mandatory features for any candidate methods delivering these strategies. Dietary therapy fits this model well, as it is simple, practical, and cost-effective, and involves diverse methods. The highest priority strategy is feeding these infants breast milk. For those who are not breast-fed, there should be a strategy to maintain beneficial gut flora that positively influences intestinal immunity. We review the current use of probiotics, prebiotics, and synbiotics, and safety and adverse effects. Other dietary modalities of possible potential in achieving this primary prevention, such as a Mediterranean diet, use of milk formula with modified (hydrolyzed) proteins, and the role of micronutrients, are also explored. Breast-feeding is effective in reducing the risk of asthma, allergic rhinitis, and atopic eczema among children. In addition, breast milk constitutes a major source of support for gut microbe colonization, due to its bifidobacteria and galactooligosaccharide content. The literature lacks consensus in recommending the addition of probiotics to foods for prevention and treatment of allergic diseases, while prebiotics may prove to be effective in reducing atopy in healthy children.

    Enhanced reactive oxygen species production in allergic airways is well described and correlates with increased airway contractions, inflammatory cell infiltration, goblet cell metaplasia, and mucus hypersecretion. There is also an abundance of interleukin-4/interleukin-13 (IL-4/IL-13)- or interleukin-5-secreting cells that are thought to be central to the pathogenesis of allergic asthma. We postulated that the dual oxidases (DUOX1 and DUOX2), members of the nicotinamide adenine dinucleotide phosphate oxidase family that release hydrogen peroxide (H2O2) in the respiratory tract, are critical proteins in the pathogenesis of allergic airways. DUOX activity is regulated by cytokines, including IL-4 and IL-13, and DUOX-mediated H2O2 influences several important features of allergic asthma: mucin production, IL-8 secretion, and wound healing. The objective of this study was to establish the contribution of DUOXs to the development of allergic asthma in a murine model. To accomplish this goal, we utilized a DUOXA-deficient mouse model (Duoxa(-/-)) that lacked maturation factors for both DUOX1 and DUOX2. Our results are the first to demonstrate evidence of DUOX protein and DUOX functional activity in murine airway epithelium. We also demonstrate that DUOXA maturation factors are required for airway-specific H2O2 production and localization of DUOX to cilia of fully differentiated airway epithelial cells. We compared wild-type and Duoxa(-/-) mice in an ovalbumin exposure model to determine the role of DUOX in allergic asthma. In comparison to DUOX-intact mice, Duoxa(-/-) mice had reduced mucous cell metaplasia and lower levels of TH2 cytokine levels in bronchoalveolar fluid. In addition, increased airway resistance in response to methacholine was observed in Duoxa(+/+) mice, as expected, but was absent in Duoxa(-/-) mice. Surprisingly, Duoxa(-/-) mice had decreased influx of neutrophils in bronchoalveolar fluid and lung tissue sections associated with a lower level of the

    We previously reported the anti-allergic effect of high molecular weight form of hyaluronic acid (HMW-HA). In doing so, HA targets CD44 and inhibits FcεRI signaling and cross-talk between epidermal growth factor receptor (EGFR) and FcεRI. We previously reported the role of histone deacetylases (HDACs) in allergic inflammation and allergic inflammation-promoted enhanced tumorigenic potential. We reported regulatory role of HA in the expression of HDAC3. In this review, we will discuss molecular mechanisms associated with anti-allergic effect of HA in relation with HDACs. The role of microRNAs (miRNAs) in allergic inflammation has been reported. We will also discuss the role of miRNAs in allergic inflammation in relation with HA-mediated anti-allergic effects.

    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

    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

    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

    The objective of this study was to evaluate humoral immunity of allergic respiratory children with chronic/recurrent sinusitis. Twenty-seven allergic respiratory (persistent mild/moderate asthma and persistent allergic rhinitis) children (7-15-year old) with chronic or recurrent sinusitis were evaluated. Patients had symptoms and abnormal computer tomography scan even after two adequate treatments (long-lasting antibiotics, decongestants, and short-term oral corticosteroids). clinical examination, sweat test, total blood cell count, measurement of serum levels of: total and specific IgE, immunoglobulins (G, M, A), IgG subclasses, antibodies to Haemophilus influenza type b (IgG anti-Ps Hib) and pneumococcal serotypes (IgG anti-Ps 1, 3, 5, 6B, 9V, and 14) before and after active immunization (Act-Hib and Pneumo23, Aventis Pasteur SA, Lyon, France), Rubella neutralizing antibody titers and human immunodeficiency virus antibodies. Specific IgE to inhalant allergens higher than class III were observed in 24/27 patients. One patient had IgA plus IgG2 deficiency and other an IgG3 deficiency. Eight and 12 of 27 patients had IgG2 and IgG3 serum levels below 2.5th percentile, respectively. Immunological responses to protein and polysaccharide antigens were normal in all patients. Although our patients have been appropriately treated of their allergic diseases, they persisted with chronic/recurrent sinusitis and 60% of them had a documented osteomeatal complex blockade. In spite of the diagnosis of IgA plus IgG2 deficiency and an isolated IgG3 deficiency, in all patients an adequate response to Ps antigens was observed. Primary and/or secondary humoral immunodeficiency seems not to be the main cause of chronic/recurrent sinusitis in patients with respiratory allergic disease. PMID:16176402
