    Sarcoidosis is one of the leading causes of inflammatory eye disease. Ocular sarcoidosis can involve any part of the eye and its adnexal tissues and may cause uveitis, episcleritis/scleritis, eyelid abnormalities, conjunctival granuloma, optic neuropathy, lacrimal gland enlargement, and orbital inflammation. Glaucoma and cataract can be complications from inflammation itself or adverse effects from therapy. Ophthalmic manifestations can be isolated or associated with other organ involvement. Patients with ocular sarcoidosis can present with a wide range of clinical presentations and severity. Multidisciplinary approaches are required to achieve the best treatment outcomes for both ocular and systemic manifestations.

    Ocular involvement occurs in sarcoidosis (Sar) patients mainly in the form of uveitis. This study was designed to determine if uveitis in Sar patients is associated with vascular impairment. We enrolled 82 Sar patients and 77, age and sex matched, control subjects (Cl). Sar patients were divided into those with ocular sarcoidosis (OS) and those without ocular sarcoidosis (WOS). Endothelial function was evaluated by flow-mediated dilation (FMD). Pulse wave velocity (PWV) was measured as an index of aortic stiffness and augmentation index (AIx) as a measure of arterial wave reflections. Although there was no significant difference in sex, age and mean arterial pressure, patients with OS compared to WOS patients and Cl subjects had impaired FMD (p<0.001), increased AIx (p=0.02) and increased PWV (p=0.001). Interestingly, impaired FMD in Sar patients was independently, from possible covariates (age, sex, smoking habits, arterial hypertension, dyslipidemia), associated with increased odds of ocular involvement (odds ratio=1.69, p=0.001). More precisely ROC curve analysis revealed that FMD had a significant diagnostic ability for the detection of OS (AUC=0.77, p<0.001) with a sensitivity of 79% and a specificity of 68% for an FMD value below 6.00%. To conclude in the present study we have shown that ocular involvement in Sar patients is associated with impaired endothelial function and increased arterial stiffness. These results strengthen the vascular theory which considers uveitis a consequence of vascular dysfunction in Sar patients and reveals a possible clinical importance of the use of endothelial function tests.

    Sarcoidosis is a multisystemic disorder of unknown cause characterized by the formation of immune granulomas in involved organs. It is an ubiquitous disease with incidence (varying according to age, sex, race and geographic origin) estimated at around 16.5/100,000 in men and 19/100,000 in women. The lung and the lymphatic system are predominantly affected but virtually every organ may be involved. Other severe manifestations result from cardiac, neurological, ocular, kidney or laryngeal localizations. In most cases, sarcoidosis is revealed by persistent dry cough, eye or skin manifestations, peripheral lymph nodes, fatigue, weight loss, fever or night sweats, and erythema nodosum. Abnormal metabolism of vitamin D3 within granulomatous lesions and hypercalcemia are possible. Chest radiography is abnormal in about 90% of cases and shows lymphadenopathy and/or pulmonary infiltrates (without or with fibrosis), defining sarcoidosis stages from I to IV. The etiology remains unknown but the prevailing hypothesis is that various unidentified, likely poorly degradable antigens of either infectious or environmental origin could trigger an exaggerated immune reaction in genetically susceptible hosts. Diagnosis relies on compatible clinical and radiographic manifestations, evidence of non-caseating granulomas obtained by biopsy through tracheobronchial endoscopy or at other sites, and exclusion of all other granulomatous diseases. The evolution and severity of sarcoidosis are highly variable. Mortality is estimated at between 0.5–5%. In most benign cases (spontaneous resolution within 24–36 months), no treatment is required but a regular follow-up until recovery is necessary. In more serious cases, a medical treatment has to be prescribed either initially or at some point during follow-up according to clinical manifestations and their evolution. Systemic corticosteroids are the mainstay of treatment of sarcoidosis. The minimal duration of treatment is 12 months. Some

    Purpose To study the impact of soluble IL2 receptor (sIL2R), chest x-ray (CxR), and angiotensin-converting enzyme (ACE) as markers for sarcoidosis in uveitis patients. Design Retrospective study. Methods Serum concentrations of sIL2R and ACE were measured in patients with active uveitis. Those with elevated sIL2R and /or ACE values were examined for suspected systemic sarcoidosis. Main Outcome Measure Our main outcome parameters were the specificity and sensitivity of sIL2R, CxR and ACE in screening for ocular sarcoidosis. Results We measured 261 patients with uveitis for sarcoidosis using sIL2R and ACE between January 2008 and November 2011; sarcoidosis was been diagnosed using other tests (e.g. computer tomography, brochoalveolar lavage, biopsy) in 41 of 53 patients with elevated sIL2R values (>639 U/ml) and in one patient with normal sIL2R (582 U/ml). Their mean sIL2R value was 1310 U/ml, extending from 582 to 8659 U/ml. Only 9 patients, however, presented elevated ACE (>82 U/l). Their mean ACE value was 116.4 U/l, ranging from 84.1 to 175.5 U/l. IL2R specificity was 94% with 98% sensitivity. In contrast, ACE had a specificity of 99.5%, but a sensitivity of only 22%; the chest x-ray had a specificity of 100% with 50% sensitivity in detecting sarcoidosis. We observed the entire spectrum of uveitis: sixteen patients suffered from anterior, 8 from intermediate, 16 from posterior, and 2 from panuveitis. Conclusions An elevated level of soluble IL2R suggests sarcoidosis with uveitis more convincingly than ACE, making sIL2R a more effective marker parameter for sarcoidosis than ACE or chest x-ray in uveitis patients.

    Sarcoidosis is a rare granulomatous disease mainly affecting lymph nodes and the lungs but joints, bones, muscles and other organs can also be affected. Sarcoidosis therefore represents an important differential diagnosis to various rheumatic diseases. For the diagnosis and differential diagnostic clarification, bronchoscopy including endobronchial ultrasound-guided fine needle aspiration of mediastinal and hilar lymph nodes represent the main procedures. Because of the high spontaneous remission rate initiating a therapy requires a therapeutic goal defined by sarcoidosis-associated functional organ impairment, especially for acute sarcoidosis. Cortisone represents the most commonly administered medication whereas methotrexate and azathioprine are well-established second-line medications. Antibodies which neutralize tumor necrosis factors (TNF) are a potential third-line therapy. PMID:27146405

    Sarcoidosis is a disease characterized by noncaseating granulomatous infiltration of 1 or more organs. In North America, after the lungs and thoracic lymph nodes, the skin is the next most commonly involved organ. Data from multiple studies indicate a coaction between genetic and environmental factors in immunologically susceptible hosts. The disease's many clinical manifestations and course vary greatly and are influenced by race, ethnicity, and gender. In the skin, the lesions of sarcoidosis are classified as specific when noncaseating granulomas are present, and nonspecific when there is an inflammatory reaction pattern devoid of granulomas.

    Introduction Sarcoidosis is a multi-organ system granulomatous disease of unknown origin with an incidence of 1–40/100,000. Though pulmonary manifestations are predominant, ocular sarcoidosis (OS) affects 25–50% of patients with sarcoidosis and can lead to blindness. Methods A retrospective, single-center chart review of sarcoidosis cases investigated variables associated with the development of OS. Inclusion criteria were biopsy-proven sarcoidosis, disease duration greater than 1 year, documented smoking status on chart review and documentation of sarcoid-related eye disease. Multivariate analysis identified independent risk factors for OS. Results Of 269 charts reviewed, 109 patients met inclusion criteria. The OS group had a significantly higher proportion of smokers (71.4%) than without OS (42.0%, p=0.027) with no difference (p=0.61) in median number of pack years. Male sex was significantly higher in the OS group (57.1% versus 26.1%, p=0.009). Median duration of sarcoidosis was higher in the OS group (10 versus 4 years, p=0.031). Multivariate regression identified tobacco exposure (OR=5.25, p=0.007, 95% CI 1.58–17.41), male sex (OR=7.48, p=0.002, 95% CI 2.15–26.01), and age (OR=1.114, p=0.002, 95% CI 1.04–1.19) as concomitant risk factors for the development of OS. Conclusion To date, there are few dedicated investigations of risk factors for OS, especially smoking. This investigation identified male sex, age, and tobacco exposure as independent risk factors for OS. Though disease duration did not withstand regression analysis in this moderately sized group, age at chart review suggests screening for OS should not remit but rather intensify in aging patients with sarcoidosis.

    Sarcoidosis is a chronic multisystem disorder characterized by an accumulation of T lymphocytes and mononuclear phagocytes, non-caseating epitheliod granulomas and derangement of normal tissue architecture in affected organs. Sarcoidosis can affect any organ system, however approximately 90% of patients with sarcoidosis have pulmonary, lymph node, cutaneous or ocular manifestations. Renal involvement in sarcoidosis is rare and clinically significant renal dysfunction even less common. We present a case of isolated renal sarcoidosis which manifested with progressively worsening renal function and hypercalcemia. A systematic diagnostic approach with pertinent laboratory studies, imaging and renal biopsy elucidated the diagnosis of renal sarcoidosis without any evidence of systemic involvement.

    Background: Psoriasiform lesions are an established, but rare, manifestation of sarcoidosis. Only 0.9 percent of patients with cutaneous sarcoidosis develop this form of the disease. Observation: The authors present a case of a 61-year-old woman with a history of pulmonary sarcoidosis who presented to their dermatology clinic with thick plaques resembling psoriasis. Biopsy of one of the lesions revealed sarcoidal granulomas in association with psoriasiform changes. Conclusion: Psoriasiform lesions are a rare manifestation of sarcoidosis. The authors theorize that the co-expression of TNF-α in both entities is a possible explanation of the psoriasiform expression of sarcoidosis. PMID:27462388

    Sarcoidosis is a multisystem granulomatous disease, of unknown cause, characterised by non-caseating granulomas. The most common organs involved are the lung, thoracic lymph nodes, skin and eyes. Ophthalmic involvement occurred in approximately 30% of the patients and could be the first manifestation of the disease and preceding pulmonary involvement for many years. If anterior uveitis is the most common ocular manifestation, the posterior segment involvement (intermediate uveitis, vasculitis, choroidal granuloma, macular oedema...) is less common but more visually disabling. The non specific ocular manifestations of the disease make it as a difficult diagnosis. The "suspected sarcoidosis" diagnosis is made with regards to clinical, radiological and (or) biological criteria and the "definitive diagnosis" require the demonstration of a non-caseating, granulomatous, non-infectious inflammation process on biopsy.

    Sarcoidosis is a multi-organ granulomatous disorder of unknown cause. Skin sarcoidosis occurs in about 25% of patients with systemic disease and may also arise in isolation. A wide range of clinical presentations of cutaneous sarcoidosis is recognised. The diagnosis rests on the presence of non-caseating granulomas on skin biopsy and the exclusion of other granulomatous skin disease. The treatment and overall prognosis of cutaneous sarcoidosis is primarily dependent on the degree of systemic involvement. In patients with aggressive disease limited to the skin immunosuppressive therapy may be indicated.

    Background: Coagulase negative Staphylococci (CoNS) are common inhabitants of human skin and mucous membranes. With the emergence of these organisms as prominent pathogens in patients with ocular infections, investigation has intensified in an effort to identify important virulence factors and to inform new approaches to treatment and prevention. Aim: To isolate CoNS from ocular specimens; to study the possible virulence factors; speciation of coagulase negative staphylococci (CoNS) which were isolated from ocular complications; antibiotic susceptibility testing of ocular CoNS. Materials and Methods: The specimens were collected from the target patients who attended the Microbiology Laboratory of a tertiary care eye hospital in Coimbatore, Tamilnadu state, India. The isolates were subjected to tube and slide coagulase tests for the identification of CoNS. All the isolates were subjected to screening for lipase and protease activities. Screening for other virulence factors viz., slime production on Congo red agar medium and haemagglutination assay with use of 96-well microtitre plates. These isolates were identified upto species level by performing biochemical tests such as phosphatase test, arginine test, maltose and trehalose fermentation tests and novobiocin sensitivity test. The isolates were subjected to antibiotic susceptibility studies, based on the revised standards of Clinical and Laboratory Standards Institutes (CLSI). Results: During the one year of study, among the total 260 individuals who were screened, 100 isolates of CoNS were obtained. Lipolytic activity was seen in all the isolates, whereas 38 isolates showed a positive result for protease. A total of 63 isolates showed slime production. Of 100 isolates, 30 isolates were analyzed for haemagglutination, where 4 isolates showed the capacity to agglutinate the erythrocytes. The results of the biochemical analysis revealed that of the 100 isolates of CoNS, 43% were Staphylococcus epidermidis. The other

    Sarcoidosis is a multisystem disease characterized by the presence of non-caseating granulomas in affected organs. Pulmonary involvement is the most common site of disease activity. However, hepatic involvement is also common in sarcoidosis, occurring in up to 70% of patients. Most patients with liver involvement are asymptomatic. Therefore, the majority of cases are discovered incidentally, frequently by the finding of elevated liver enzymes. Pain in the right upper quadrant of the abdomen, fatigue, pruritus, and jaundice may be associated with liver involvement. Portal hypertension and cirrhosis are complications linked to long-standing hepatic sarcoidosis. Liver biopsy is usually required to confirm the diagnosis. It is important to differentiate hepatic sarcoidosis from other autoimmune and granulomatous liver diseases. Not all cases of hepatic sarcoidosis require treatment. For symptomatic patients, the first line treatment includes corticosteroids or ursodeoxycholic acid. Various immunosuppressant agents can be used as second line agents. Rarely, severe cases require liver transplantation.

    Sarcoidosis is seen in different parts of India and other developing countries with almost similar frequency as in the West. It was largely due to lack of awareness and non-availability of investigations for diagnosis that the disease was reported to be rare in the past. A combination of clinical, radiologic, and histologic criteria are used to diagnose sarcoidosis. A confident exclusion of other causes of granuloma formation, especially tuberculosis, is required. Absence of mycobacteria and of caseation in the histologic specimens and presence of skin anergy to tuberculin help make a diagnosis. Transbronchial lung biopsy obtained with the help of fiberoptic bronchoscopy is positive in about 80% of patients. Corticosteroids are used to treat patients with symptoms and those showing active organ involvement. Aggressive treatment is required for patients with acute and severe pulmonary, cardiac, ocular, or neurologic involvements.

    In sarcoidosis, reduction in mortality and the prevention of disability due to major organ involvement are treatment goals. Thus, it is important to recognize severe disease and identify patients at higher risk of progression to severe disease. In this article, fibrotic lung disease and cardiac sarcoidosis are reviewed as the major contributors to sarcoidosis mortality and morbidity. In the absence of a standardized definition of severe pulmonary disease, a multidisciplinary approach to clinical staging is suggested, based on symptoms, pulmonary function tests, and imaging findings at presentation, integrated with the duration of disease and longitudinal disease behavior during early follow-up.

    Studies suggest clinically manifest cardiac involvement occurs in 5% of patients with pulmonary/systemic sarcoidosis. The principal manifestations of cardiac sarcoidosis (CS) are conduction abnormalities, ventricular arrhythmias, and heart failure. Data indicate that an 20% to 25% of patients with pulmonary/systemic sarcoidosis have asymptomatic (clinically silent) cardiac involvement. An international guideline for the diagnosis and management of CS recommends that patients be screened for cardiac involvement. Most studies suggest a benign prognosis for patients with clinically silent CS. Immunosuppression therapy is advocated for clinically manifest CS. Device therapy, with implantable cardioverter defibrillators, is recommended for some patients.

    Sarcoidosis is a multisystem granulomatous disease of unknown etiology. Tumor necrosis factor (TNF)-alpha is an important player in granuloma formation, and recent clinical trials have investigated the efficacy of TNF-alpha inhibitors in sarcoidosis. Paradoxically, there are several case reports in the medical literature describing the development of sarcoidosis in patients treated with TNF-alpha inhibitors. We describe 3 cases of TNF-alpha antagonist-induced sarcoidosis: 1 case of pulmonary, ocular and cutaneous sarcoidosis developing in a patient receiving infliximab for erosive rheumatoid arthritis, 1 case of etanercept-induced sarcoidosis in a patient with seronegative rheumatoid arthritis, and 1 case of sarcoidosis developing in a patient receiving etanercept for erosive rheumatoid arthritis. We also provide a brief discussion on the role of TNF alpha in granuloma formation and implications in the use of TNF-alpha antagonists in autoimmune disease.

    Sarcoidosis is a multisystem disease of unknown aetiology. Histological evidence of non-caseating granulomas represents the main finding. It affects mostly young people, targeting primary the lung and hilar lymph nodes although liver involvement is often encountered. Hepatic sarcoidosis covers a broad spectrum from asymptomatic hepatic granulomas formation and slightly deranged liver function tests to clinically evident disease with cholestasis or, in advanced cases, cirrhosis and portal hypertension. Other granulomatous diseases (mainly systemic infections like tuberculosis) should be excluded prior to treatment, as longstanding corticosteroid administration is the main stem of therapy. In advanced cases, liver transplantation represents the ultimate therapeutic option.

    Sarcoidosis is characterized by formation of epithelioid-cell tubercules, without caseation, of the affected organ systems. The mediastinum, peripheral lymph nodes and eyes, in addition to the skin, are most frequently affected. Between 10% and 30% of patients with systemic sarcoidosis in Japan have skin lesions. Skin sarcoidosis is morphologically classified into three basic groups, erythema nodosum, scar sarcoidosis and skin sarcoid. Skin sarcoid is characterized by specific cutaneous lesions of sarcoidosis, and may take nodular, plaque, angiolupoid, subcutaneous and some other forms. Clinical manifestations of the cutaneous lesions are usually asymptomatic and polymorphous. Skin biopsy is, however, often highly useful for confirming a diagnosis of sarcoidosis.

    Abstract Sarcoidosis is a granulomatous disease that most frequently affects the lungs with pulmonary infiltrates and/or bilateral hilar and mediastinal lymphadenopathy. An association of sarcoidosis and lymphoproliferative disease has previously been reported as the sarcoidosis-lymphoma syndrome. Although this syndrome is characterized by sarcoidosis preceding lymphoma, very few cases of sarcoidosis following lymphoma have been reported. We describe the clinical, biological, and radiological characteristics and outcome of 39 patients presenting with sarcoidosis following lymphoproliferative disease, including 14 previously unreported cases and 25 additional patients, after performing a literature review. Hodgkin lymphoma and non-Hodgkin lymphoma were equally represented. The median delay between lymphoma and sarcoidosis was 18 months. Only 16 patients (41%) required treatment. Sarcoidosis was of mild intensity or self-healing in most cases, and overall clinical response to sarcoidosis was excellent with complete clinical response in 91% of patients. Sarcoidosis was identified after a follow-up computerized tomography scan (CT-scan) or 18fluorodeoxyglucose-positron emission tomography/computerized tomography (18FDG-PET/CT) evaluation in 18/34 patients (53%). Sarcoidosis is therefore a differential diagnosis to consider when lymphoma relapse is suspected on a CT-scan or 18FDG-PET/CT, emphasizing the necessity to rely on histological confirmation of lymphoma relapse.

    Sarcoidosis is a chronic systemic disease of unknown origin and uncertain prognosis that most commonly affects young adults, and frequently presents with bilateral hilar lymphadenopathy, pulmonary infiltrates and ocular and skin lesions. The diagnosis is established when characteristic clinical-radiological features are supported by compatible histopathology of epithelioid cell granulomas, following exclusion of known causes of granulomatous inflammation. Indeed, sarcoidosis belongs to a large family of disorders that share granuloma formation as common denominator. Since its first description by Jonathan Hutchinson in 1869, sarcoidosis has generated enormous interest and considerable controversy. In Hutchinson's day, it was considered a dermatological condition, which gradually evolved into a multisystem disorder associated in the majority of cases with respiratory abnormalities. With time, it has also become clear that sarcoidosis occurs throughout the world, affecting individuals of both genders and all races, although its prevalence varies widely across ethnic and racial groups. In recent years, advances in different disciplines, particularly biochemistry, genetics, immunology and molecular biology, have improved dramatically our understanding of the disease. Yet, the critical questions regarding who gets sarcoidosis and whether it has an infectious origin remain unanswered. Sarcoidosis has a distinguished medical history that covers the last 150 years. Right from the time of seminal contributions by Hutchinson, Besnier and Boeck medical discussion on sarcoidosis has always been animated and to a certain extent emotional. Such discussions will inevitable continue until the true cause of the disease has been found, hopefully in the near future.

    During the last decade, many biochemical and immunologic advances have been made in the treatment and understanding of sarcoidosis. These studies have helped us to understand the basic mechanisms involved in granuloma formation, and many clinicians have used the information to diagnose and assess the activity of sarcoidosis. Further studies are needed to clearly establish the role of these advances in the everyday management of patients with sarcoidosis.

    Sarcoidosis is a disease with highly variable presentation and progression; although it is hypothesized that disease phenotype is related to genetic variation, how much of this variability is driven by genetic factors is not known. The HLA region is the most strongly and consistently associated genetic risk factor for sarcoidosis, supporting the notion that sarcoidosis is an exposure-mediated immunologic disease. Most of the genetic etiology of sarcoidosis remains unknown in terms of the specific variants that increase risk in various populations, their biologic functions, and how they interact with environmental exposures.

    Sarcoidosis is a multisystem granulomatous disease of unknown etiology that most commonly affects the lungs. Treatment of sarcoidosis can be challenging as it is often difficult to measure disease activity and distinguish active inflammation from fibrosis. Identifying the inflammatory mediators in sarcoidosis has led to the development and use of novel therapeutic agents. The goal of pharmacotherapy is to decrease granuloma accumulation, ameliorate symptoms and improve organ function. Systemic corticosteroids remain the first line treatment. Other immunosuppressive agents may be considered for the patients who respond poorly to corticosteroids or who experience significant adverse effects. An overview of pharmacotherapy of sarcoidosis is provided here.

    Corticosteroids are the drug of choice for the treatment of sarcoidosis. Because the natural course of sarcoidosis may be self-limiting and/or cause no long-term harm, treatment is not mandatory. Corticosteroids are usually effective for all forms of sarcoidosis, and they work quickly. However, because of the potential toxicities of corticosteroids, alternative medications often need to be considered. Efforts should be made to minimize the corticosteroid dose while keeping the risk of toxicity as low as possible. This article outlines the indications for corticosteroid therapy for sarcoidosis, discusses various dosing regimens, and suggests when alternative corticosteroid agents should be considered.

    Sarcoidosis is a systemic, clinically heterogeneous disease characterized by the development of granulomas. Any organ system can be involved, and patients may present with any number of rheumatologic symptoms. There are no U.S. Food and Drug Administration-approved therapies for the treatment of sarcoidosis. Diagnosing sarcoidosis becomes challenging, particularly when its complications cause patients' symptoms to mimic other conditions, including polymyositis, Sjögren syndrome, or vasculitis. This review presents an overview of the etiology of and biomarkers associated with sarcoidosis. We then provide a detailed description of the rheumatologic manifestations of sarcoidosis and present a treatment algorithm based on current clinical evidence for patients with sarcoid arthritis. The discussion will focus on characteristic findings in patients with sarcoid arthritis, osseous involvement in sarcoidosis, and sarcoid myopathy. Arthritic conditions that sometimes coexist with sarcoidosis are described as well. We present two cases of sarcoidosis with rheumatologic manifestations. Our intent is to encourage a multidisciplinary, translational approach to meet the challenges and difficulties in understanding and treating sarcoidosis.

    Since sarcoidosis was first described more than a century ago, the etiologic determinants causing this disease remain uncertain. Studies suggest that genetic, host immunologic, and environmental factors interact together to cause sarcoidosis. Immunologic characteristics of sarcoidosis include non-caseating granulomas, enhanced local expression of T helper-1 (and often Th17) cytokines and chemokines, dysfunctional regulatory T-cell responses, dysregulated Toll-like receptor signaling, and oligoclonal expansion of CD4+ T cells consistent with chronic antigenic stimulation. Multiple environmental agents have been suggested to cause sarcoidosis. Studies from several groups implicate mycobacterial or propionibacterial organisms in the etiology of sarcoidosis based on tissue analyses and immunologic responses in sarcoidosis patients. Despite these studies, there is no consensus on the nature of a microbial pathogenesis of sarcoidosis. Some groups postulate sarcoidosis is caused by an active viable replicating infection while other groups contend there is no clinical, pathologic, or microbiologic evidence for such a pathogenic mechanism. The authors posit a novel hypothesis that proposes that sarcoidosis is triggered by a hyperimmune Th1 response to pathogenic microbial and tissue antigens associated with the aberrant aggregation of serum amyloid A within granulomas, which promotes progressive chronic granulomatous inflammation in the absence of ongoing infection.

    Sarcoidosis, a systemic granulomatous disease of undetermined etiology, is characterized by a variable clinical presentation and course. During the past decade, advances have been made in the study of sarcoidosis. The multicenter ACCESS (A Case Control Etiologic Study of Sarcoidosis) trial recruited > 700 subjects with newly diagnosed sarcoidosis and matched control subjects. Investigators were unable to identify a single cause of sarcoidosis, but ACCESS paved the way for subsequent etiologic studies. The Mycobacterium tuberculosis catalase-peroxidase protein has been identified as a potential sarcoidosis antigen. Genetic aspects of the disease have been elucidated further. Genome-wide scans have identified candidate genes. Gene expression analyses have defined cytokine dysregulation in sarcoidosis more clearly. Although the criteria for diagnosis have not changed, sarcoidosis remains a diagnosis of exclusion best supported by a tissue biopsy specimen that demonstrates noncaseating granulomas in a patient with compatible clinical and radiologic features of the disease. Endobronchial ultrasound-guided transbronchial needle aspiration of mediastinal lymph nodes has facilitated diagnosis, often eliminating the need for more invasive procedures, such as mediastinoscopy. PET scanning has proven valuable in locating occult sites of active disease. Currently, no reliable prognostic biomarkers have been identified. The tumor necrosis factor inhibitors, a relatively new class of agents, have been used in patients with refractory disease. It is unclear whether phosphodiesterase-5 inhibitors, prostaglandin analogs, or endothelin antagonists should be used for the treatment of sarcoidosis-associated pulmonary hypertension.

    Sarcoidosis is a chronic, inflammatory, multi-organ disease of unknown origin that is characterized by non-caseating granuloma formation in affected organs. Cutaneous involvement is reported in 25% of patients with sarcoidosis. Scar sarcoidosis is rare but is clinically specific for skin sarcoidosis. Systemic involvement is seen in most patients with scar sarcoidosis. We present a case of scar sarcoidosis in a 30-year-old male that developed infiltrated nodules on old scars, including on his penile shaft, which is rare, and that also had pulmonary involvement. Scar sarcoidosis should be considered in the differential diagnosis of changes in all scar areas and should be investigated for systemic involvement.

    Sarcoidosis is a multisystem granulomatous disease of unknown etiology. The organs that are involved by sarcoidosis include the lungs in which the granuloma is seen in more than 90% of patients to the pituitary, which is only rarely affected. There are many hypotheses as to the cause of sarcoidosis. Some of them rely on the similarities seen between sarcoidosis and the other granuloma-forming diseases such as tuberculosis, berylliosis, pine pollen inhalation and acute and chronic bacterial and viral infections, while others find similarities between sarcoidosis and immune reactions observed in autoimmune disorders. Still other explanations implicate a genetic predisposition or a still-unknown agent as the underlying cause of the granuloma formation. Images PMID:3310401

    The diagnostic imaging contributes significantly to the diagnosis and management of sarcoidosis. Imaging techniques are widely employed in the assessment of thoracic and extra-thoracic involvement from sarcoidosis. For the diagnosis of sarcoidosis, chest radiograph has been the cornerstone of sarcoidosis since 1961, when Scadding proposed a standardized staging system. Currently, computed tomography (CT) represents the reference standard for the assessment of both mediastinal lymph nodes and pulmonary findings. In particular, high-resolution computed tomography (HRCT) is more accurate compared to chest radiography for the detection of subtle parenchymal involvement, and provides comprehensive overview of anatomical detail and abnormalities of lung structures. Notably, HRCT allows for accurate differentiation between reversible and irreversible lung disease, which is cornerstone of prognostication. Radionuclide imaging (gallium-67 and (18)F-fluorodeoxyglucose) provides information about activity of the disease and is also useful for diagnostic workup of patients with unexplained persistent disabling symptoms. Magnetic resonance is sensitive for the detection of sarcoidosis granulomata within myocardium, thus providing detailed roadmap for biopsy. For the management of sarcoidosis, CT is of paramount importance in the detection and differential of most common complications, such as vascular disease and suspicious nodular lesions. Conversely, the role of CT in the follow-up of asymptomatic subjects is still under debate. This review focuses on the role of diagnostic imaging in the diagnosis and follow-up of sarcoidosis.

    Sarcoidosis is a multisystem inflammatory disorder of unknown cause. It most commonly affects the pulmonary system but can also affect the musculoskeletal system, albeit less frequently. In patients with sarcoidosis, rheumatic involvement is polymorphic. It can be the presenting symptom of the disease or can appear during its progression. Articular involvement is dominated by nonspecific arthralgia, polyarthritis, and Löfgren's syndrome, which is defined as the presence of lung adenopathy, arthralgia (or arthritis), and erythema nodosum. Skeletal manifestations, especially dactylitis, appear mainly as complications of chronic, multiorgan sarcoidosis. Muscle involvement in sarcoidosis is rare and usually asymptomatic. The diagnosis of rheumatic sarcoidosis is based on X-ray findings and magnetic resonance imaging findings, although the definitive diagnosis is made by anatomopathological study of biopsy samples. Musculoskeletal involvement in sarcoidosis is generally relieved with nonsteroidal anti-inflammatory drugs or corticosteroids. In corticosteroid-resistant or -dependent forms of the disease, immunosuppressive therapy, such as treatment with methotrexate or anti-TNF-α, is employed. The aim of this review was to present an overview of the various types of osteoarticular and muscle involvement in sarcoidosis, focusing on their diagnosis and management. PMID:24831403

    The cochleovestibular tract is seldom involved by sarcoidosis (about 50 cases have been described since 1948). As a clinical expression of sarcoidosis, deafness is fluctuant in 50% of all cases, bilateral, and most often associated with facial palsy and uveitis, the vestibular reflexes being reduced. The histological studies demonstrate lesions at all levels from the cochlea to be brain stem, but the main mechanism is an infiltration of the arachnoid vessels. The prognosis of sarcoidosis deafness is usually poor in spite of corticosteroid therapy. This paper is illustrated by 3 cases observed in Avicenne Hospital.

    The diagnosis of sarcoidosis, a systemic granulomatous disease, is based on a compatible clinical-radiological picture and the histological evidence of noncaseating granulomas. Other diseases mimicking sarcoidosis, mostly infections and other granulomatoses, have to be excluded. There is no single test for sarcoidosis, and the presence of granulomas alone does not establish the diagnosis. Symptoms of sarcoidosis are not specific and can be markedly different according to organ involvement and disease course. Respiratory symptoms and fatigue are the most common symptoms at any stage of disease. Histological confirmation is not needed for Löfgren's or Heerfordt's syndrome and asymptomatic bihilar lymphadenopathy. The radiological staging system is still based on chest radiography, and computed tomography is not mandatory for routine follow-up. (18)F-fluorodeoxyglucose positron emission tomography may be of value in special cases. For assessment of lung involvement and follow-up, pulmonary function tests are necessary with vital capacity being the most important single parameter and diffusion capacity the most sensitive. Bronchoscopy with biopsy is the most common procedure for detection of granulomas, when there is no easier biopsy site like skin or peripheral lymph nodes. Endobronchial ultrasonography-guided transbronchial needle aspiration has replaced mediastinoscopy for evaluation of mediastinal and hilar lymph nodes with a high diagnostic yield. Despite numerous studies, no single biomarker can be reliably used for correct diagnosis or exclusion of sarcoidosis. Genetic testing, despite promising advances, has still not been included in routine care for sarcoidosis patients. The long-term prognosis of sarcoidosis depends on the different organ manifestations: Cardiac or central nervous involvement, together with respiratory complications, is critical. A multidisciplinary approach is necessary for comprehensive care of the sarcoidosis patient.

    Sarcoidosis is a chronic multisystemic inflammatory disorder of unknown etiology, characterized by the presence of non-necrotizing epithelioid and giant cell granulomas. Various renal manifestations have been reported in patients with sarcoidosis. Disorders of bone and mineral metabolism related to the overexpression of 25-hydroxyvitamin-D1α-hydroxylase by alveolar and granuloma macrophages are frequently associated with sarcoidosis. Hypercalcemia and hypercalciuria are a major cause of renal injury predisposing to pre renal azotemia, acute tubular necrosis, nephrolithiasis and nephrocalcinosis. Therapeutic management of hypercalcemia includes preventive measures (limited sunlight exposure, limited vitamin D and calcium intakes, and adequate hydration) and specific treatment in cases of severe hypercalcemia (corticosteroid therapy, chloroquine or ketoconazole). Granulomatous tubulointerstitial nephritis is the most common renal lesion associated with sarcoidosis leading to end stage renal disease in some patients. In these cases, interstitial fibrosis seems to appear early in the course of sarcoidosis and is a major prognostic factor requiring rapid corticosteroid therapy to reduce the risk of severe renal impairment. Membranous nephropathy seems to be the most frequent glomerular disease that may occur in association with sarcoidosis. Among kidney allograft recipients, the risk of recurrence of granulomatous tubulointerstitial nephritis is high and may have a negative impact on the graft survival.

    Sarcoidosis is an inflammatory disease of unknown etiology. Most commonly it results in the formation of non-caseating granulomas in intrathoracic lymph nodes and lung parenchyma, but the clinical course and picture may be complicated by extrapulmonary involvement and many non-respiratory signs and symptoms which are directly related to the disease. In addition, sarcoidosis patients may suffer from a plethora of symptoms of uncertain or unknown origin. Fatigue is one of these symptoms, and according to some authors it is reported by the majority of patients with active sarcoidosis, but also by a smaller proportion of patients with inactive sarcoidosis, or even with complete clinical and radiological remission. Therefore the term fatigue syndrome is frequently used to name this clinical problem. The definition of fatigue syndrome in sarcoidosis is imprecise and the syndrome is usually recognized by use of validated questionnaires. In this review the uptodate knowledge in this field was presented and different challenges connected with this syndrome were described.

    Introduction. Sarcoidosis is a rare multisystemic granulomatous inflammatory disease of unknown etiology affecting the respiratory system, skin, and eyes. Sarcoidosis outside the lacrimal gland is rare. The case study concerns a patient with a final diagnosis of orbital sarcoidosis. Case Report. A 37-year-old male patient went to the ophthalmic emergency room complaining of pain in the left eye, diplopia, and decreased visual acuity. An external eye examination showed hard and cold edema of the lower eyelid, ocular motility with limitation of adduction, and discreet ipsilateral proptosis. Magnetic resonance of the orbit showed left eye proptosis and thickening and increase of soft tissues associated with heterogeneous impregnation of contrast in the infralateral region of the left eyelid. A biopsy of the lesion showed a chronic inflammatory process, with numerous compact nonnecrotizing granulomas surrounded by lamellar hyaline collagen, providing histological confirmation of sarcoidosis. Discussion. A biopsy of the orbital tumor is essential for the diagnosis of sarcoidosis, in addition to the search for systemic findings such as hilar adenopathy or parenchymal lung disease found in 90% of patients.

    Abstract Background: Cryptococcal meningitis is an uncommon but severe complication of sarcoidosis. Methods: We present 2 patients with cryptococcal meningitis complicating sarcoidosis and compared findings with 38 cases reported in the literature. Results: When analyzing our patients and 38 cases reported in the literature, we found that median age of sarcoidosis patients with cryptococcal meningitis was 39 years (range 30–48); 27 of 33 reported cases (82%) had a history of sarcoidosis. Only 16 of 40 patients (40%) received immunomodulating therapy at the time of diagnosis of cryptococcal meningitis. The diagnosis of cryptococcal meningitis was delayed in 17 of 40 patients (43%), mainly because of the initial suspicion of neurosarcoidosis. Cerebrospinal fluid (CSF) examination showed mildly elevated white blood cell count (range 23–129/mm3). Twenty-nine of 32 cases (91%) had a positive CSF culture for Cryptococcus neoformans and 25 of 27 cases (93%) had a positive CSF C neoformans antigen test. CD4 counts were low in all patients in whom counts were performed (84–228/mL). Twelve patients had an unfavorable outcome (32%), of which 7 died (19%) and 24 patients (65%) had a favorable outcome. The rate of unfavorable outcome in patients with a delayed diagnosis was 7 of 17 (41%) compared to 5 of 28 (21%) in patients in whom diagnosis was not delayed. Conclusion: Cryptococcal meningitis is a rare but life-threatening complication of sarcoidosis. Patients were often initially misdiagnosed as neurosarcoidosis, which resulted in considerable treatment delay and worse outcome. CSF cryptococcal antigen tests are advised in patients with sarcoidosis and meningitis. PMID:27583871

    Sarcoidosis is a disease involving abnormal collection of inflammatory cells forming nodules, called granulomas. Such granulomas occur in the lung and the mediastinal lymph nodes, in the heart, and in other vital and nonvital organs. The origin of the disease is unknown, and there are only limited clinical data on lung tissue of patients. No current model of sarcoidosis exists. In this paper we develop a mathematical model on the dynamics of the disease in the lung and use patients’ lung tissue data to validate the model. The model is used to explore potential treatments.

    A woman was referred to our hospital with the working diagnosis of ovarian malignancy. While she was undergoing both clinical and radiological evaluation and monitoring, a decrease in the size of the ovarian mass was noted. After further evaluation via laboratory findings and tissue biopsy, we arrived at a final diagnosis of sarcoidosis, which is very unusual in the ovaries. Our case places emphasis on the importance of considering rare entities, such as ovarian sarcoidosis, and the importance of radiologic changes in solid ovarian mass dimensions over time.

    Sarcoidosis is a multisystem disorder of unknown cause(s). Less specific disabling symptoms, including fatigue and physical impairments, may have a major influence on the daily activities and the social and professional lives of the patients, resulting in a reduced quality of life. A multidisciplinary approach focusing on somatic and psychosocial aspects is recommended. Patients self-perceived knowledge about the importance of exercise and lifestyle should be improved. Developing the most appropriate therapeutic approach for sarcoidosis requires careful consideration of the possible impact of fatigue, small fiber neuropathy related symptoms, pain, cognitive functioning, and coping strategies. Personalized medicine and appropriate communication are beneficial. PMID:26593145

    We reported about intrathoracic changes and prognosis of 686 patients with sarcoidosis diagnosed in our hospital between 1963 and 1988. We evaluated CT findings in 135 patients with sarcoidosis and found pulmonary involvements in 81. We analyzed CT findings according to the classification by Tuengerthal which classified radiographic findings combining ILO classification of pneumoconiosis and characteristic findings of bronchovascular sheath with sarcoidosis. The CT findings were as follows: small opacities (44 out of 81 cases, 54.3%), large opacities (37 cases, 46.7%). Additional findings were as follows: peribronchial marking (42 cases, 51.9%), contraction (17 cases, 21.0%), pleural involvement (9 cases, 11.1%), bulla (5 cases, 6.2%). The characteristic CT findings of serious sarcoidosis were extasis of bronchus, thickening of the bronchial wall, unclearness of vascular shadow, atelectasis and thickening of pleura. Concerning the prognosis of pulmonary involvement, according to age, patients younger than 30 years old at initial diagnosis were better than those of 30 years and over in terms of disappearance of pulmonary involvements. According to stage, patients of stage I and stage II were better than those of stage III. Among the patients we were able to observe chest X-ray findings during five years according to the character of shadow, ill-defined shadow of small opacities and rounded shadows of large opacities had a higher disappearance rate of pulmonary involvements than irregular shadows of large opacities, atelectasis and contraction.

    IMPORTANCE Sarcoidosis is a major cause of ocular or periocular inflammation. The pathogenesis of sarcoidosis is incompletely understood and diagnosis often requires a biopsy. OBJECTIVE To determine how gene expression in either orbital adipose tissue or the lacrimal gland affected by sarcoidosis compares with gene expression in other causes of orbital disease and how gene expression in tissue affected by sarcoidosis compares with gene expression in peripheral blood samples obtained from patients with sarcoidosis. DESIGN, SETTING, AND PARTICIPANTS In a multicenter, international, observational study, gene expression profiling of formalin-fixed biopsy specimens, using GeneChipp U133 Plus 2 microarrays (Affymetrix), was conducted between October 2012 and January 2014 on tissues biopsied from January 2000 through June 2013. Participants included 12 patients with orbital sarcoidosis (7 in adipose tissue; 5 affecting the lacrimal gland) as well as comparable tissue from 6 healthy individuals serving as controls or patients with thyroid eye disease, nonspecific orbital inflammation, or granulomatosis with polyangiitis. In addition, results were compared with gene expression in peripheral blood samples obtained from 12 historical individuals with sarcoidosis. MAIN OUTCOMES AND MEASURES Significantly differentially expressed transcripts defined as a minimum of a 1.5-fold increase or a comparable decrease and a false discovery rate of P < .05. RESULTS Signals from 2449 probe sets (transcripts from approximately 1522 genes) were significantly increased in the orbital adipose tissue from patients with sarcoidosis. Signals from 4050 probe sets (approximately 2619 genes) were significantly decreased. Signals from 3069 probe sets (approximately 2001 genes) were significantly higher and 3320 (approximately 2283 genes) were significantly lower in the lacrimal gland for patients with sarcoidosis.

    Sarcoidosis is a multisystem granulomatous disorder invariably affecting the lungs. It is a disease with noteworthy variations in clinical manifestation and disease outcome and has been described as an “immune paradox” with peripheral anergy despite exaggerated inflammation at disease sites. Despite extensive research, sarcoidosis remains a disease with undetermined aetiology. Current evidence supports the notion that the immune response in sarcoidosis is driven by a putative antigen in a genetically susceptible individual. Unfortunately, there currently exists no reliable biomarker to delineate the disease severity and prognosis. As such, the diagnosis of sarcoidosis remains a vexing clinical challenge. In this review, we outline the immunological features of sarcoidosis, discuss the evidence for and against various candidate etiological agents (infective and noninfective), describe the exhaled breath condensate, a novel method of identifying immunological biomarkers, and suggest other possible immunological biomarkers to better characterise the immunopathogenesis of sarcoidosis.

This case emphasises the importance of including sarcoidosis in the differential diagnosis of bilateral parotid swelling. PMID:22533935

    Sarcoidosis is a chronic granulomatous disease of unknown aetiology. It can affect any part of the organism, although the lung is the most frequently affected organ. Upper airway involvement is rare, particularly if isolated. Sarcoidosis is a diagnosis of exclusion, established by histological evidence of non-caseating granulomas and the absence of other granulomatous diseases. The authors report a case of a man with sarcoidosis manifesting as a chronic inflammatory stenotic condition of the upper respiratory tract and trachea.

    Three cases of micropapular sarcoidosis are reported. Two of the cases have a history of tuberculosis and all three cases have atypical patterns of Kveim and Mantoux reactivity. The similarities between this form of sarcoidosis and lichen scrofulosorum or lichenoid tuberculid are observed and the evidence is presented for a tuberculoid aetiology in certain forms of sarcoidosis.

    The objective of this review is to highlight the clinical utility of FDG-PET/CT for evaluation of patients with chronic sarcoidosis. The emphasis was on the potential advantages and disadvantages of this technique in these patients based on which recommendations were made. The advantage of FDG-PET/CT technique is that it can visualize FDG accumulation in activated inflammatory cells and simultaneously provide PET and CT images. Of particular interest is the use of FDG-PET/CT for the staging and identification of occult sites and sites suitable for biopsy and for the assessment of inflammatory active sarcoidosis in patients with prolonged symptoms, especially when other markers of the disease are within normal values. FDG-PET/CT also provides a better visualization of extrathoracic sites of active sarcoidosis, such as in the bones, liver, spleen, and retroperitoneal lymph nodes. The use of FDG-PET/CT is of special interest in cardiac sarcoidosis because this potentially life-threatening disease is sometimes present in asymptomatic patients. FDG-PET/CT also has a role in the clinical management of patients with chronic persistent sarcoidosis, such as for planning treatment, monitoring response, and long-term follow-up. The limitations of FDG-PET/CT in patients with sarcoidosis are discussed in the context of a "sarcoidosis-lymphoma syndrome" and potentially excessive radiation exposure. Further prospective multicentre studies are needed to refine the clinical applications of FDG-PET/CT in patients with sarcoidosis and drive the field forward.

    A patient who had had pulmonary sarcoidosis for 11 years developed multiple symmetrical lesions with ulcerations on the lower legs. The lesions showed the typical clinical picture of necrobiosis lipoidica and could not be differentiated histologically with certainty. Three years later persistent reddish plaques appeared on both arms, which allowed clinical and histological diagnosis of cutaneous sarcoidosis.

    Sarcoidosis is a granulomatous disorder of unknown cause, affecting multiple organs, but mainly the lungs. The exact order of immunological events remains obscure. Reviewing current literature, combined with careful clinical observations, we propose a model for granuloma formation in pulmonary sarcoidosis. A tight collaboration between macrophages, dendritic cells, and lymphocyte subsets, initiates the first steps toward granuloma formation, orchestrated by cytokines and chemokines. In a substantial part of pulmonary sarcoidosis patients, granuloma formation becomes an on-going process, leading to debilitating disease, and sometimes death. The immunological response, determining granuloma sustainment is not well understood. An impaired immunosuppressive function of regulatory T cells has been suggested to contribute to the exaggerated response. Interestingly, therapeutical agents commonly used in sarcoidosis, such as glucocorticosteroids and anti-TNF agents, interfere with granuloma integrity and restore the immune homeostasis in autoimmune disorders. Increasing insight into their mechanisms of action may contribute to the search for new therapeutical targets in pulmonary sarcoidosis. PMID:24339826

    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

    Sarcoidosis is an inflammatory disorder characterized by noncaseating granulomas infiltrating affected organs. Any organ system can be involved, and more than 90 % of patients have a primary pulmonary manifestation. The incidence of radiographically evident bone involvement has been reported over a wide range: from 3 to 39 % depending on the population studied and imaging modalities used. Any bone may be affected in osseous sarcoidosis. Bilateral involvement of the phalanges of the hand and feet is most common. However, reports of long bone, skull, rib and vertebral involvement have appeared. To date, there are no specific tools for the assessment of skeletal disease activity in sarcoidosis. Plain radiograph picks lesions in the small bones of hands and feet greater than does in other bones. Bone scan is useful for defining the extent of the skeletal disease and bone marrow involvement. Magnetic resonance imaging usually demonstrates multifocal lesions within the vertebrae that are hypointense on T1-weighted images and hyperintense on T2-weighted images. In cases of multifocal bone lesions and an established diagnosis of sarcoidosis, a diagnosis of bone sarcoidosis should be considered in the differential diagnosis. Optimal treatment of osseous sarcoidosis remains controversial. We present five cases of multisystem sarcoidosis with skeletal involvement including long bones and vertebrae and a description of immunosuppressive therapies used in our patients. A literature review highlighting the diagnostic approach using radiographic imaging, as well as treatment strategies, is provided.

    Sarcoidosis is characterized by noncaseating granulomas containing CD4(+) T cells with a Th1 immunophenotype. Although the causative antigens remain unknown, independent studies noted molecular and immunologic evidence of mycobacterial virulence factors in sarcoidosis specimens. A major limiting factor in discovering new insights into the pathogenesis of sarcoidosis is the lack of an animal model. Using a distinct superoxide dismutase A peptide (sodA) associated with sarcoidosis granulomas, we developed a pulmonary model of sarcoidosis granulomatous inflammation. Mice were sensitized by a subcutaneous injection of sodA, incorporated in incomplete Freund's adjuvant (IFA). Control subjects consisted of mice with no sensitization (ConNS), sensitized with IFA only (ConIFA), or with Schistosoma mansoni eggs. Fourteen days later, sensitized mice were challenged by tail-vein injection of naked beads, covalently coupled to sodA peptides or to schistosome egg antigens (SEA). Histologic analysis revealed hilar lymphadenopathy and noncaseating granulomas in the lungs of sodA-treated or SEA-treated mice. Flow cytometry of bronchoalveolar lavage (BAL) demonstrated CD4(+) T-cell responses against sodA peptide in the sodA-sensitized mice only. Cytometric bead analysis revealed significant differences in IL-2 and IFN-γ secretion in the BAL fluid of sodA-treated mice, compared with mice that received SEA or naked beads (P = 0.008, Wilcoxon rank sum test). ConNS and ConIFA mice demonstrated no significant formation of granuloma, and no Th1 immunophenotype. The use of microbial peptides distinct for sarcoidosis reveals a histologic and immunologic profile in the murine model that correlates well with those profiles noted in human sarcoidosis, providing the framework to investigate the molecular basis for the progression or resolution of sarcoidosis.

    Sarcoidosis is a chronic granulomatous disease of unknown cause that is seen worldwide and occurs mainly in patients between the ages of 20 and 60 years. It can be difficult to diagnose because it can mimic many other diseases including lymphoproliferative disorders and granulomatous infections and because there is no specific test for diagnosis, which depends on correlation of clinicoradiologic and histopathologic features. This review will focus on recent discoveries regarding the pathogenesis of sarcoidosis, common clinical presentations, diagnostic evaluation, and indications for treatment. This review is aimed largely at general practitioners and emphasizes the importance of differentiating pulmonary sarcoidosis from its common imitators. PMID:27378039

    Technetium-99m (/sup 99m/Tc)-labeled pyrophosphate or diphosphonate compounds and gallium-67 citrate (/sup 67/Ga) are two radionuclide scanning agents that are in widespread use in clinical practice. Technetium-99m pyrophosphate is used extensively for bone scanning to detect metastatic bone disease, benign bone tumors, osteomyelitis, benign hypertrophic osteoarthropathy, and Paget's disease. Only two reports describe abnormal /sup 99m/Tc/ pyrophosphate bone scans in four patients with osseous sarcoidosis. Gallium-67 scans are used primarily to localize neoplastic or inflammatory lesions anywhere in the body. In recent years /sup 67/Ga scans have also been used to detect the presence of both pulmonary and extrapulmonary sarcoidosis, but there are no reports describing abnormal uptake of gallium in patients with osseous sarcoidosis. This report describes experience with radioisotope scanning in two patients with osseous sarcoidosis.

    Background: Increased production of nitric oxide (NO) by the lower respiratory tract is viewed as a marker of airway inflammation in asthma and bronchiectasis. NO is a potentially important immune modulator, inhibiting the release of several key pro-inflammatory cytokines. As sarcoidosis is characterised by granulomatous airway inflammation, we hypothesised that exhaled NO levels might be raised in sarcoidosis and correlate with the morphological extent and functional severity of disease. Methods: Fifty two patients with sarcoidosis (29 men) of mean age 42 years underwent thin section computed tomography (CT), pulmonary function tests, and measurement of exhaled NO. Results: Exhaled NO levels (median 6.8 ppb, range 2.4–21.8) did not differ significantly from values in 44 control subjects, and were not related to the extent of individual CT abnormalities or the level of pulmonary function impairment. Conclusion: Exhaled NO levels are not increased in pulmonary sarcoidosis. PMID:16244094

    Pulmonary disease due to talc, a group of hydrous magnesium silicates, is almost exclusively encountered secondary to occupational exposure or intravenous drug abuse. Talcosis or talc pneumoconiosis is one of the rarer forms of silicate-induced lung disease. It is seen in workers exposed during its production, and occasionally, in users of cosmetic talc and in intravenous drug addicts. Very often, the history of exposure is not recognised by the patient, and it is only the finding of granulomatous cellular interstitial lesions containing birefringent crystals which indicates considerable talc exposure. We report a 38-year-old woman who was initially diagnosed with sarcoidosis, until a bronchoscopic biopsy revealed the presence of numerous foreign body giant cells and birefringent particles forming non-caseating granulomas. There was no history of occupational exposure to talc or intravenous drug abuse. The patient responded to oral corticosteroid treatment. Talcosis is generally considered to be relatively benign.

A wide range of clinical presentations of cutaneous sarcoidosis is recognised. The diagnosis rests on the presence of non-caseating granulomas on skin biopsy. Treatment and overall prognosis of cutaneous sarcoidosis is primarily dependent on the degree of systemic involvement.

    A 40-year-old Caucasian man presented to the dermatology clinic at Baylor College of Medicine, Houston, Texas, in February 2003, for the evaluation of three nonhealing ulcers. The patient's past medical history was significant for hypothyroidism and pulmonary sarcoidosis, the diagnosis of which was made in June 2000. In March 2000, the patient had complained of cough and shortness of breath. A purified protein derivative (PPD) (Mantoux text) was negative. Computed tomography (CT) scans of the chest revealed diffuse hilar and mediastinal adenopathy and bilateral interstitial and alveolar infiltrates. Although consistent with sarcoidosis, these findings were insufficient to exclude other etiologies, including disseminated fungal infection. Cultures and stains of subsequent bronchoscopy specimens failed to reveal any organisms, and histopathologic evaluation of the specimens was nondiagnostic. Based on the imaging studies and the negative cultures, a diagnosis of sarcoidosis was made, and the patient was started on therapy with prednisone. Before coming to our clinic, the patient had been on several courses of prednisone. In May 2002, the patient had presented to a private dermatologist with a 1-year history of a nonhealing 2.4 cm x 2.0 cm ulcer on the left medial forearm. Two biopsies were reported as nondiagnostic. The patient's presentation was interpreted as most consistent with Mycobacterium marinum infection, and so he was empirically treated with minocycline. This treatment was continued for almost 3 months without improvement in the ulcer. A few months after the minocycline had been discontinued, the patient was treated empirically for 2 months with ciprofloxacin. This treatment was also unsuccessful in ameliorating the ulcer. In between the two courses of antibiotics, specimens from the lesion were sent for bacterial and fungal cultures, which revealed normal skin flora. In January 2003, the patient returned to his private dermatologist with three ulcerations

    Patients with hepatic sarcoidosis rarely require orthotopic liver transplantation (OLT). Progression of granulomatous activity involving other organs after OLT has rarely been described. We describe a 32-year-old woman who underwent liver transplantation for sarcoidosis-associated end-stage liver disease. She presented 4 years later with shortness of breath, hilar lymphadenopathy, and interstitial lung abnormalities. Liver functions were normal. Open lung biopsy results revealed granulomata compatible with sarcoidosis. The patient made a complete recovery after corticosteroid treatment. To the best of our knowledge, this is a first description of severe exacerbation of pulmonary sarcoidosis in an immunosuppressed patient who underwent liver transplantation for sarcoidosis-associated liver disease.

There was multisystem involvement with marked hepatosplenomegaly, generalized lymphadenopathy, parotid fullness and chronic uveitis. Pulmonary infiltrates were seen on the chest X-ray. Histology of a skin biopsy showed naked noncaseating granulomata and PCR for Mycobacterium tuberculosis was negative. A clinical diagnosis of sarcoidosis was made. The patient was treated with oral prednisolone (2 mg/kg per day). An excellent clinical response with resolution of the rash and improvement of extracutaneous signs was noted within 3 months and she remains well on low-dose prednisolone on alternate days. We discuss the presentation and management of sarcoidosis in children, and highlight the potential difficulty in differentiating this from disseminated tuberculosis.

    Sarcoidosis is a systemic non caseous granulomas disease. Liver is a common location but usually asymptomatic. Evidence based guidelines for this location treatment is lacking and the effect of corticosteroids may be inadequate. The aim of our study was to describe the clinical, biochemical, radiological and therapeutic features of seven patients with systemic sarcoidosis and liver involvement. A retrospective and descriptive monocentric study, over 3 years, including seven patients with systemic sarcoidosis and liver involvement. We included 5 women and 2 men with an average age of 43 years. Hepatic localization revealed sarcoidosis in 5 cases. Hepatomegaly was observed in all patients as well as abnormal serum liver function test reflected by anicteric cholestasis. Liver biopsy, showed in all granulomatous lesions consistent with sarcoidosis and severe fibrosis in 2 cases. Extra-hepatic manifestations were present in all patients represented mainly by pulmonary location. All patients were treated, five by corticosteroid and two with ursodeoxycholic acid (UDCA). Complete response was observed in one case, partial response in another case and corticosteroid refractoriness in one case. In two cases, corticosteroid therapy was introduced for less than 1 month, not allowing assessment of response. Antimalarials in combination with UDCA were used successfully in a patient with steroid-resistant liver disease. Liver involvement can reveal systemic sarcoidois. Given the risk of progression to severe liver disease, it must be screened in all patients with systemic sarcoidosis. Treatment is not systematic, and still based on corticosteroid therapy. In the absence of prospective randomized controlled trials, the efficacy of UDCA need to be proven. PMID:27795804

    Neuromyelitis optica (NMO) is an autoimmune disorder diagnosed by an elongated spinal cord lesion associated with unilateral or bilateral optic neuritis and anti-aquaporin 4 (AQP4) antibodies in the serum. It is triggered by or associated with several autoimmune diseases, but not with sarcoidosis. It responds to immunomodulators better than to steroid treatment. Sarcoidosis is an autoimmune disorder which manifests as non-caseating granulomas, usually in the lung parenchyma, but also in other tissues, including the brain. The involvement of the central nervous system in neurosarcoidosis differs considerably from that in neuromyelitis optica and the association of these two diseases concurrently in the same patient is unusual.

    Cardiac sarcoidosis is one of the most serious and unpredictable aspects of this disease state. Heart involvement frequently presents with arrhythmias or conduction disease, although myocardial infiltration resulting in congestive heart failure may also occur. The prognosis in cardiac sarcoidosis is highly variable, which relates to the heterogeneous nature of heart involvement and marked differences between racial groups. Electrocardiography and echocardiography often provide the first clue to the diagnosis, but advanced imaging studies using positron emission tomography and MRI, in combination with nuclear isotope perfusion scanning are now essential to the diagnosis and management of this condition. The identification of clinically occult cardiac sarcoidosis and the management of isolated and/or asymptomatic heart involvement remain both challenging and contentious. Corticosteroids remain the first treatment choice with the later substitution of immunosuppressive and steroid-sparing therapies. Heart transplantation is an unusual outcome, but when performed, the results are comparable or better than heart transplantation for other disease states. We review the epidemiology, developments in diagnostic techniques and the management of cardiac sarcoidosis.

    Cavitation in pulmonary sarcoidosis is rather unusual and even rarer in the alveolar form of the disease. A review of the literature revealed only 13 documented patients with cavitating alveolar sarcoidosis. Of the 13 patients, clinical information was available in only eight cases. Aspergilloma complicating cavitary alveolar sarcoidosis has been documented only once before. A 38-year-old woman with progressive dyspnoea for 3 years presented owing to a bout of haemoptysis. Imaging prior to presentation demonstrated mediastinal lymphadenopathy and coalescent parenchymal alveolar opacities along with air bronchograms, suggestive of alveolar sarcoidosis. On presentation, cavitations were visible in both lungs within the consolidation along with an intracavitary mass in the left upper lobe, which on evaluation was recognised as an aspergilloma. Bronchoscopy disclosed non-caseating granulomas on histopathology confirming pulmonary sarcoidosis. Cavitary alveolar sarcoidosis with aspergilloma formation can result in a diagnostic dilemma, especially in endemic tuberculous areas. PMID:25326564

    Sarcoidosis is a multisystem inflammatory disorder of unknown etiology. It shows a great variety of clinical presentation, organ involvement, and disease progression. Lungs and lymphoid system are the most common sites involved with a frequency of 90% and 30%, respectively. Extrapulmonary involvement of sarcoidosis is reported in 30% of patients and abdomen is the most frequent site. Furthermore, peritoneal involvement is extremely rare in sarcoidosis. The case presented here described peritoneal manifestations of sarcoidosis without involvement of lungs. A 78-year-old woman possessing signs of malignancy on blood test and abdominal magnetic resonance imaging underwent laparatomy with a suspicion of ovarian malignancy. The macroscopic interpretation during surgery was peritoneal carcinomatosis. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, peritoneal biopsies, total omentectomy, and appendectomy were performed. Final histopathological result revealed the diagnosis of sarcoidosis. Clinicians must keep in mind that peritoneal sarcoidosis can mimic intra-abdominal malignancies. PMID:26558122

    Sarcoidosis is a multisystemic disease of unknown etiology. Up to 30% of patients develop cutaneous manifestations, either specific or nonspecific. Ulcerating sarcoidosis leading to leg ulcers is a rare observation that may lead to confusions with other, more common types of chronic leg ulcers. We report the case of a 45-year-old female patient with chronic multisystemic sarcoidosis presenting with pretibial leg ulcers. Other etiology could be excluded. Histology revealed nonspecific findings. Therefore, the diagnosis of nonspecific leg ulcers in sarcoidosis was confirmed. Treatment consisted of oral prednisolone and good ulcer care. Complete healing was achieved within 6 months. Sarcoidosis is a rare cause of leg ulcers and usually sarcoid granulomas can be found. Our patient illustrates that even in the absence of sarcoid granulomas, leg ulcers can be due to sarcoidosis. PMID:27272316

    Sarcoidosis is a systemic granulomatous disease of undetermined etiology characterized by a variable clinical presentation and disease course. Although clinical granulomatous inflammation may occur within any organ system, more than 90% of sarcoidosis patients have lung disease. Sarcoidosis is considered an interstitial lung disease that is frequently characterized by restrictive physiologic dysfunction on pulmonary function tests. However, sarcoidosis also involves the airways (large and small), causing obstructive airways disease. It is one of a few interstitial lung diseases that affects the entire length of the respiratory tract - from the nose to the terminal bronchioles - and causes a broad spectrum of airways dysfunction. This article examines airway dysfunction in sarcoidosis. The anatomical structure of the airways is the organizational framework for our discussion. We discuss sarcoidosis involving the nose, sinuses, nasal passages, larynx, trachea, bronchi and small airways. Common complications of airways disease, such as, atelectasis, fibrosis, bullous leions, bronchiectasis, cavitary lesions and mycetomas, are also reviewed. PMID:22082167

    Gingivitis due to sarcoidosis is a relatively rare condition. Gingivitis or isolated gingival involvement may be the first sign of systemic sarcoidosis. We report the case of a 37 year-old woman with isolated gingivitis due to sarcoidosis confirmed by biopsy. Following treatment with a systemic corticosteroid (prednisolone 40 mg/day), all clinical and radiologic findings were completely improved. In cases of chronic and intractable gingivitis, systemic sarcoidosis should be suspected. It should be confirmed with a biopsy, and the patient should be referred to a chest disease clinic to exclude other organ involvement.

    A 70-year-old woman with an 8-year history of systemic sarcoidosis developed round, red-brown eruptions, with central atrophic lesions on her lower legs. The features of the biopsy specimen resembled those of necrobiosis lipoidica (NL), but although necrobiosis was present there were well-formed non-necrotizing granulomas in the dermis. The histological diagnosis was cutaneous sarcoidosis. Systemic sarcoidosis presenting with NL has rarely been reported. The histological features of cutaneous sarcoidosis sometimes mimic those of other granulomatous diseases, including NL and granuloma annulare, which are difficult to distinguish. We discuss the novel association between sarcoidosis and other granulomatous diseases. PMID:22363160

    The sera of 50 patients with sarcoidosis were tested for the presence of circulating immune complexes using polyethylene glycol precipitation, followed by single radial immuno diffusion for the amounts of Clg, IgG, IgM, and double diffusion for the presence of IgA. Complexes were detected in 29 (58%) patients. No correlation could be found between the presence of these complexes and the length of history stage, or activity of disease, nor to steroid therapy. Rheumatoid factor was detected in 14 patients (28%), 13 of whom had circulating immune complexes, and 12 of whom had active disease. Total serum C3, CH50, and Clq were normal, as were immunoglobulin levels. In patients with extrathoracic sarcoidosis, especially skin or joint involvement, complexes were commonly found. The aetiological significance of these complexes remains uncertain. PMID:7434270

    More than 140 years since its recognition as a clinical entity, sarcoidosis remains enigmatic. Its classification as a disease vs. a syndrome is uncertain. Its etiology remains undefined. The "immune paradox" (delayed type hypersensitivity anergy in a setting of exuberant systemic granulomatous response) resists explanation. Its relationship to the Kveim test is poorly understood. Its prognostic determinants and treatment indications are among the unsolved or disputed problems. Immunological investigations generated the thesis that the characterizing systemic granuloma arise as a fallback reaction to inefficient cellular immune processing, due most often to impaired myeloid dendritic cell function of unknown cause. The concept that sarcoidosis represents a (genetically conditioned) default to a more primitive immunological response provides a unifying explanation for its development in persons with a variety of antigenic exposures and in individuals with cellular immune deficiencies. It furnishes a coherent explanation for the apparent paradox that individuals exhibiting the most intense cellular response experience the most favorable outcomes and for the adverse effect of corticosteroid-suppression in recent onset sarcoidosis.

    Sarcoidosis is a multisystem granulomatous disease of unknown cause that can affect the heart. Cardiac sarcoidosis may be present in as many as 25% of patients with systemic sarcoidosis, and it is frequently underdiagnosed. The early and accurate diagnosis of myocardial involvement is challenging. Advanced imaging techniques play important roles in the diagnosis and management of patients with cardiac sarcoidosis.

    Diseases responsive to glucocorticoids, like sarcoidosis, are rarely masked by Cushing's syndrome. An ACTH secreting pituitary adenoma is a possible cause of Cushing's syndrome and its resection can make a subclinical sarcoidosis clear. Only few cases of sarcoidosis following the treatment of hypercortisolism are reported in literature. We report a case of sarcoidosis after the resection of an ACTH secreting pituitary adenoma.

    We present a case of probable pulmonary sarcoidosis associated with the use of etanercept for psoriatic arthritis. Other cases of etanercept-induced granulomas and skin sarcoidosis were recently published in the medical literature, but we found only one case that involved lung sarcoidosis during etanercept therapy. We describe a 40-year-old man who was receiving etanercept for severe psoriatic arthritis and was admitted to the hospital with dyspnea and subfebrile illness several months after the start of treatment. His diagnosis was consistent exclusively with sarcoidosis. The patient's symptoms improved when etanercept was discontinued, but they did not resolve completely. Treatment with prednisone 40 mg led to complete improvement of his pulmonary disease. Etanercept therapy can induce or exacerbate sarcoidosis. The disease disappears when etanercept is discontinued, although treatment with corticosteroids is sometimes required, as in our patient. Use of the Naranjo adverse drug reaction probability scale revealed a probable likelihood (score of 6) that the adverse reaction was related to etanercept. The association of etanercept with sarcoidosis is still a rare finding. This case highlights the importance of monitoring and possibly discontinuing the drug when sarcoidosis is suspected. Patients should be monitored during and after etanercept therapy for manifestations suggesting sarcoidosis, and we recommend patients receive baseline chest radiography at the start of therapy with follow-up of respiratory symptoms.

    Sarcoidosis is a multisystem disorder of unknown cause, and cardiac sarcoidosis affects at least 25% of patients and accounts for substantial mortality and morbidity from this disease. Cardiac sarcoidosis may present with heart failure, left ventricular systolic dysfunction, AV block, atrial or ventricular arrhythmias, and sudden cardiac death. Cardiac involvement can be challenging to detect and diagnose because of the focal nature of the disease, as well as the fact that clinical criteria have limited diagnostic accuracy. Nevertheless, the diagnosis of cardiac sarcoidosis can be enhanced by integrating both clinical and imaging findings. This article reviews the various roles that different imaging modalities provide in the evaluation and management of patients with known or suspected cardiac sarcoidosis.

  4. Shortfalls in imputing sarcoidosis to occupational exposures.

    PubMed

    Reich, Jerome M

    2013-04-01

    The cause of sarcoidosis remains elusive. Reports of elevated sarcoidosis incidence in New York City firefighters and World Trade Center disaster responders have been advanced to support a causal relationship. This inference is open to question due to methodological differences in assessing and computing sarcoidosis incidence in populations versus putative occupational exposures. The magnitude of the odds ratio (OR; ca. 1.5) of causal candidates in the ACCESS case-control study of occupational and environmental exposures is sufficiently small that it might easily be attributable to confounders. Additionally, multiplicity of comparisons, difficulty in assembling a valid control population and the potential for recall bias critically limit causal inferences. A possible explanation for etiological elusiveness and multiplicity of elevated OR is that individuals with sarcoidosis, lacking components of efficient cellular immunity, respond with systemic granulomas to a variety of ubiquitous, frequently unidentifiable environmental antigens. Epidemiological methods for the identification of sarcoidosis causal candidates are potentially misleading and are unlikely to prove useful.

    Gastrointestinal sarcoidosis is a rare form of extrapulmonary sarcoidosis. Most of the cases are represented by gastric involvement. We describe a patient with previous systemic sarcoidosis who presented with non-specific abdominal complaints. The workup showed the unusual combination of isolated active gastric sarcoidosis and quiescent activity of the disease elsewhere. We briefly review the clinical, diagnostic and therapeutic aspects of gastric sarcoidosis. We hope to increase awareness about this rare disease.

    2015-05-01

    Cardiac sarcoidosis is a potentially life-threatening condition characterized by formation of granulomas in the heart, resulting in conduction disturbances, atrial and ventricular arrhythmias, and ventricular dysfunction. The presentation of cardiac sarcoidosis ranges from asymptomatic with an abnormal imaging scan, to palpitations, syncope, symptoms of congestive heart failure, and sudden cardiac death. Screening for cardiac sarcoidosis has not been standardized, but the presence of cardiac symptoms on medical history and physical examination, and an abnormal electrocardiogram (ECG), Holter monitoring, or echocardiogram has been shown to be highly sensitive for detecting cardiac sarcoidosis. A signal-averaged ECG might also have a role in screening for cardiac sarcoidosis in asymptomatic patients. Although endomyocardial biopsies are highly specific for the diagnosis of cardiac sarcoidosis, procedural yield is very low and appropriate findings on cardiac MRI or PET are, therefore, often used as diagnostic surrogates. Treatment for cardiac sarcoidosis usually involves immunosuppressive therapy, particularly corticosteroids. Additional therapy might be required, depending on the clinical presentation, including implantation of an internal defibrillator, antiarrhythmic agents, and catheter ablation.

    Sarcoidosis is a multisystem inflammatory disease of unknown etiology. The lungs and the lymphoid system are the most commonly involved organs. Extrapulmonary involvement is reported in 30% of patients, and the abdomen is the most common extrapulmonary site with a frequency of 50%–70%. Although intra-abdominal sarcoidosis is usually asymptomatic, its presence may affect the prognosis and treatment options. The lesions are less characteristic and may mimick neoplastic or infectious diseases such as lymphoma, diffuse metastasis, and granulomatous inflammation. The liver and spleen are the most common abdominal sites of involvement. Sarcoidosis of the gastrointestinal system, pancreas, and kidneys are extremely rare. Adenopathy which is most commonly found in the porta hepatis, exudative ascites, and multiple granulomatous nodules studding the peritoneum are the reported manifestations of abdominal sarcoidosis. Since abdominal sarcoidosis is less common and long-standing, unrecognized disease can result in significant morbidity and mortality. Imaging contributes to diagnosis and management of intra-abdominal sarcoidosis. In this report we reviewed the cross-sectional imaging findings of hepatobiliary, gastrointestinal, and genitourinary sarcoidosis. PMID:25512071

    Sarcoidosis is a complex disorder that often times involves the head and neck. Despite the presence of strong clinical evidence, tissue diagnosis and imaging is needed for confirmation of the disease. Although typically managed medically, when found in the sinonasal tract or intracranially, it may necessitate the intervention of a rhinologist-skull base surgeon. This article seeks to provide a comprehensive review of head and neck sarcoidosis, as this fascinating disorder often poses a diagnostic and therapeutic challenge. A brief discussion of surgical treatment for pituitary lesions is also provided. Articles from 1997 to 2013 were selected and reviewed by three researchers utilizing the most recent literature regarding sarcoidosis in the head and neck. PubMed searches were conducted using search terms such as "sarcoidosis", "neurosarcoid", and "extra-pulmonary sarcoid", among many others. A large collection of articles was generated and reviewed by the team of authors, and appropriate information was extracted to compose a thorough and expansive review of the subject. 10-15 % of patients with sarcoidosis have head and neck manifestations. Sinonasal and pituitary sarcoidosis presents a diagnostic challenge owing to its non-specific symptoms. Although systemic steroid therapy is often the first time treatment, endoscopic surgery is commonly used to treat advanced pituitary sarcoidosis refractory to medical management. As tissue diagnosis and imaging is key, a multi-disciplinary team approach is advantageous. Our study collates the available literature on head and neck sarcoidosis to provide a comprehensive review of the subject. This provides helpful information to guide all practitioners involved in the care of these challenging patients, namely pathologists, radiologists, otolaryngologists, and skull base surgeons, in the workup and management of head and neck sarcoidosis.

  10. Interrelationship between sleep-disordered breathing and sarcoidosis.

    PubMed

    Lal, Chitra; Medarov, Boris I; Judson, Marc A

    2015-10-01

    Sleep-disordered breathing (SDB) has a high prevalence in sarcoidosis. This high prevalence may be the result of increased upper airways resistance from sarcoidosis of the upper respiratory tract, corticosteroid-induced obesity, or parenchymal lung involvement from sarcoidosis. OSA is a form of SDB that is particularly common in patients with sarcoidosis. Sarcoidosis and SDB share many similar symptoms and clinical findings, including fatigue, gas exchange abnormalities, and pulmonary hypertension (PH). Sarcoidosis-associated fatigue is a common entity for which stimulants may be beneficial. Sarcoidosis-associated fatigue is a diagnosis of exclusion that requires an evaluation for the possibility of OSA. Hypercapnia is unusual in a patient with sarcoidosis without severe pulmonary dysfunction and, in this situation, should prompt evaluation for alternative causes of hypercapnia, such as SDB. PH is usually mild when associated with OSA, whereas the severity of sarcoidosis-associated PH is related to the severity of sarcoidosis. PH caused by OSA usually responds to CPAP, whereas sarcoidosis-associated PH commonly requires the use of vasodilators. Management of OSA in sarcoidosis is problematic because corticosteroid treatment of sarcoidosis may worsen OSA. Aggressive efforts should be made to place the patient on the lowest effective dose of corticosteroids, which involves early consideration of corticosteroid-sparing agents. Because of the significant morbidity associated with SDB, early recognition and treatment of SDB in patients with sarcoidosis may improve their overall quality of life.

  11. A critical analysis of sarcoidosis incidence assessment.

    PubMed

    Reich, Jerome M

    2013-01-01

    Valid sarcoidosis incidence assessment is contingent on access to medical care, thoroughness of reportage, assiduity of radiographic interpretation, employment and health care screening policies, misclassification, and population ethnicity. To diminish ambiguity and foster inter-population comparison, the term "sarcoidosis incidence" must be modified to convey the methodology employed in compiling the numerator. In age-delimited cohorts, valid comparison to population incidence requires age adjustment due to the age-dependency of incidence. The "true incidence" of sarcoidosis is a notional concept: more than 90% of cases are subclinical and radiographically inevident. Occupational causal inference based on incidence differential vs. populations has been undermined by methodological differences in ascertainment and computation.

    We studied the high resolution CT (HRCT) scans of 15 patients with biopsy-proven sarcoidosis and correlated the findings with pulmonary function tests (12 patients), 67Ga scans (10 patients), bronchoalveolar lavage (five patients), recent transbronchial biopsy (six patients), and recent open lung biopsy (three patients). The HRCT features included small nodules, thickened interlobular septa, patchy focal increase in lung density, honeycombing, and central conglomeration of vessels and bronchi. Active alveolitis was present by gallium scanning criteria in 5 of 10 cases. By bronchoalveolar lavage criteria, activity was present in three of five cases. Patchy increase in density may correlate with active alveolitis as seen on /sup 67/Ga scanning. High resolution CT was better than chest X-radiography for demonstration of patchy increase in density and for distinguishing nodules from septal thickening. Both nodules and patchy density were partly reversible following therapy. Nodular densities seen on CT correlated with the presence of granulomata on histology. Resting pulmonary function tests correlated poorly with presence and extent of lung disease on HRCT. The presence on HRCT of focal fine nodules, patchy focal increase in lung density, and central crowding of bronchi and vessels should suggest the diagnosis of sarcoidosis. In some patients, HRCT can identify unsuspected parenchymal lung disease and document the reversible components of sarcoid lung disease.

    Sarcoidosis is a systemic inflammatory disease characterized by the development of noncaseating granulomas in multiple organ systems. Many hematologic malignancies and solid tumors, including melanoma, have been associated with sarcoidosis. We describe the clinical and pathologic findings of a 54-year-old man with melanoma-associated sarcoidosis. In addition, we not only review the literature describing characteristics of other melanoma patients with sarcoidosis, but also the features of melanoma patients with antineoplastic therapy-associated sarcoidosis. Sarcoidosis has been described in 80 melanoma patients; sufficient information for analysis was provided in 39 of these individuals. In 43.6% of individuals (17 out of 39), sarcoidosis was directly associated with melanoma; in 56.4% of oncologic patients (22 out of 39), sarcoidosis was induced by antineoplastic therapy that had been administered for the treatment of their metastatic melanoma. The discovery of melanoma preceded the development of sarcoidosis in 12 of the 17 (70.5%) individuals who did not receive systemic treatment. Pulmonary and/or cutaneous manifestations of sarcoidosis were common among both groups of patients. Most patients did not require treatment for sarcoidosis. Melanoma patients—either following antineoplastic therapy or without systemic treatment—may be at an increased risk to develop sarcoidosis. In antineoplastic therapy naive melanoma patients, a common etiologic factor—such as exposure to ultraviolet light—may play a role in their developing melanoma and sarcoidosis. PMID:26083934

    Subcutaneous sarcoidosis is the specific subset of cutaneous sarcoidosis frequently associated with systemic disease. However, the disease activity, severity, and prognosis have not yet been elucidated due to the limited number of reported cases. The purpose of this study was to identify the clinical, laboratory, and prognostic differences between subcutaneous sarcoidosis and other type of cutaneous sarcoidosis. All patients with sarcoidosis diagnosed histopathologically from 2000 to 2012 at our institution were enrolled. The clinical, laboratory, chest X-ray, and pulmonary function test results were retrospectively evaluated in the patients with cutaneous sarcoidosis. In the 130 patients with sarcoidosis, cutaneous sarcoidosis was diagnosed in 37 patients (28.4 %), and 9 (6.9 %) of these patients had subcutaneous sarcoidosis. The serum levels of soluble interleukin-2 receptor (sIL-2R) were significantly elevated in the group of patients with subcutaneous sarcoidosis in comparison to the patients with other types of cutaneous sarcoidosis, whereas there was no significant difference in the severity score between the two groups. Following a 2-year observation period, three patients were in remission, five patients demonstrated stable disease, and one patient had progressive disease. Subcutaneous sarcoidosis may be associated with the disease activity, although it was not found to be associated with the disease severity and it was not a predictive factor for the prognosis. Furthermore, the prevalence of subcutaneous sarcoidosis may be higher than that in previously reported series. PMID:27449952

    Background: leishmaniasis infection might manifest as sarcoidosis; on the other hand, some evidences propose an association between sarcoidosis and leishmaniasis. Most of the times, it is impossible to discriminate idiopathic sarcoidosis from leishmaniasis by conventional histopathologic exam. Aim: We performed a cross-sectional study to examine the association of sarcoidosis with leishmaniasis in histopathologically diagnosed sarcoidal granuloma biopsy samples by polymerase chain reaction (PCR). Materials and Methods: We examined paraffin-embedded skin biopsy samples obtained from patients with clinical and histopathological diagnosis as naked sarcoidal granuloma, referred to Skin Research Center of Shaheed Beheshti Medical University from January 2001 to March 2010, in order to isolate Leishmania parasite. The samples were reassessed by an independent dermatopathologist. DNA extracted from all specimens was analyzed by the commercially available PCR kits (DNPTM Kit, CinnaGen, Tehran, Iran) to detect endemic Leishmania species, namely leishmania major (L. major). Results: L. major was positive in PCR of Eight out of twenty-five examined samples. Conclusion: Cutaneous leishmaniasis may be misinterpreted as sarcoidosis; in endemic areas, when conventional methods fail to detect Leishmania parasite, PCR should be utilized in any granulomatous skin disease compatible with sarcoidosis, regardless of the clinical presentation or histopathological interpretation.

    A 36-year-old man visited our hospital because of blurred vision and redness of the conjunctiva. Slit-lamp examination showed panuveitis. Two days later, he suddenly experienced dizziness, speech disturbance, paralysis of his right extremities, and gait disturbances. Neurological examinations suggested that his symptoms were caused by a left lateral medullary lesion. He also had erythema mainly on his trunk. Magnetic resonance imaging (MRI) of his brain demonstrated a small infarct on the left side of the medulla oblongata. Clinical presentation and MRI findings were consistent with the diagnosis of a Wallenberg's syndrome. He also had bilateral hilar lymphadenopathy. A skin biopsy showed granulomatous nodular dermatitis compatible with sarcoidosis. He was treated with steroid pulse therapy and his neurological and ocular symptoms immediately improved. Only seven similar cases of intracranical sarcoidosis have been reported, but none had been treated with steroid pulse therapy. We recommend that steroid pulse therapy be considered to treat patients with sarcoidosis with signs of lesions in the central nervous system. PMID:22431930

    Subcutaneous sarcoidosis occurs infrequently among cases of cutaneous sarcoidosis. To our knowledge, few studies have described the sonographic characteristics of subcutaneous sarcoidosis. Here we report the sonographic characteristics of 3 cases of this condition. Our results revealed 4 features: (1) an irregular hypoechoic appearance, (2) heterogeneous echogenicity, (3) perilesional hyperechoic changes, and (4) abnormal Doppler signals. Sonography is a rapid, simple, and noninvasive procedure that is useful for initial evaluation of granulomatous lesions such as subcutaneous sarcoidosis.

    PubMed

    1986-01-01

    Torticollis can arise from nonocular (usually musculoskeletal) and ocular conditions. Abnormal head position for ocular reasons is usually assumed in order to maintain binocularity and/or to optimize visual acuity. A variety of conditions may be responsible. The sensory organ of position sense, the labyrinth, lies within the inner ear and it relates to eye movement in both a dynamic and static fashion. The Bielschowsky head tilt test is based on the functioning of the otolithic apparatus and is the primary test in evaluating abnormal head position. Treatment is usually surgical, with extent and location dependent upon on the underlying cause. While corrective surgery has usually been done on an elective basis for cosmetic purposes, there is evidence that uncorrected torticollis can cause musculoskeletal problems. This review describes the physiological bases for ocular torticollis and the diagnosis and treatment of its various underlying causes.

    2015-07-01

    Perineural granulomas in cutaneous sarcoidosis have been rarely reported and their clinical significance has yet to be evaluated. Recently, a 27-year-old male presented with multiple pink papules on the flank and lower back, accompanied by a painful, burning sensation. Biopsies revealed well-defined granulomas, consistent with sarcoidosis, in the dermis and involving small cutaneous nerves. We hypothesized that perineural granulomas may be an under-recognized feature of cutaneous sarcoidosis and may be responsible for sensory disturbances. We reviewed cases from 29 consecutive patients with cutaneous sarcoidosis. Perineural granulomas were identified in 18/29 (62%) patients and in 22/40 (55%) biopsies. Perineural granulomas were identified in 7/9 biopsies from the proximal upper extremity, 1/3 from the distal upper extremity, 7/12 from the head and the neck, including 4/4 from the nose, 5/9 from the back, 1/2 from the flank and 1/1 from the proximal lower extremity and 0/4 from the distal lower extremity. The anatomical distribution is similar to sarcoidosis small-fiber neuropathy (SSFN), in which sarcoidosis patients without evident skin lesions experience sensory disturbances of unknown etiology involving the face, the proximal extremities and the trunk. Our results indicate perineural granulomas in cutaneous sarcoidosis are more common than previously appreciated, primarily involve the head, the proximal upper extremities and the back, and may be responsible for neurological manifestations.

    Sarcoidosis is a multisystem disorder of unknown origin, characterized by the accumulation of lymphocytes and mononuclear histiocytes inducing the formation of noncaseating "naked" epithelioid granulomas. The lungs, lymphatic system, and skin are most often affected, but sarcoidosis may affect any organ. Cutaneous involvement of sarcoidosis is often the sentinel sign of the disease, with the skin sometimes being exclusively affected. We present a case of a 54-year-old African American woman with long-standing history of pulmonary sarcoidosis that presented with multiple verrucous cutaneous lesions on the upper and lower extremities mimicking carcinoma. The initial cutaneous biopsy was superficial in nature, and the pathologist raised the consideration of a possible keratoacanthoma. A deeper skin shave biopsy was performed, and the histopathology showed verrucous pseudoepitheliomatous epidermal hyperplasia with scattered noncaseating granulomas in the superficial dermis. Stains (acid-fast bacillus, Periodic acid-Schiff, and Gomori-Grocott methenamine silver stains) were negative for microorganisms. Given the clinical setting and histomorphology of the cutaneous lesions, the diagnosis of verrucous sarcoidosis was rendered. Verrucous sarcoidosis is a rare cutaneous manifestation of sarcoidosis that could be easily misdiagnosed if it is not appropriately biopsied. This hinders the precise evaluation of the histological specimen, overall clinical picture, and administration of appropriate therapy. PMID:23344007

  1. The Clinical Features of Sarcoidosis: A Comprehensive Review.

    PubMed

    Judson, Marc A

    Sarcoidosis has innumerable clinical manifestations, as the disease may affect every body organ. Furthermore, the severity of sarcoidosis involvement may range from an asymptomatic state to a life-threatening condition. This manuscript reviews a wide variety of common and less common clinical characteristics of sarcoidosis. These manifestations are presented organ by organ, although additional sections describe systemic and multiorgan presentations of sarcoidosis. The lung is the organ most commonly involved with sarcoidosis with at least 90 % of sarcoidosis patients demonstrating lung involvement in most series. The skin, eye, liver, and peripheral lymph node are the next most commonly clinically involved organs in most series, with the frequency of involvement ranging from 10 to 30 %. The actual frequency of sarcoidosis organ involvement is probably much higher as it is frequently asymptomatic and may avoid detection. This is particularly common with lung, liver, cardiac, and bone involvement. Cardiac sarcoidosis is present in 25 % of all sarcoidosis but only causes clinical problems in 5 % of them. Nevertheless, unlike sarcoidosis involvement of most other organs, it may be suddenly fatal. Therefore, it is important to screen for cardiac sarcoidosis in all sarcoidosis patients. All sarcoidosis patients should also be screened for eye involvement as asymptomatic patients may have eye involvement that may cause permanent vision impairment. Pulmonary fibrosis from sarcoidosis is usually slowly progressive but may be life-threatening because of the development of respiratory failure, pulmonary hypertension, or hemoptysis related to a mycetoma or bronchiectasis. Some manifestations of sarcoidosis are not organ-specific and probably are the result of a release of mediators from the sarcoid granuloma. Two such manifestations include small fiber neuropathy and fatigue syndromes, and they are observed in a large percentage of patients.

    Sarcoidosis has innumerable clinical manifestations, as the disease may affect every body organ. Furthermore, the severity of sarcoidosis involvement may range from an asymptomatic state to a life-threatening condition. This manuscript reviews a wide variety of common and less common clinical characteristics of sarcoidosis. These manifestations are presented organ by organ, although additional sections describe systemic and multiorgan presentations of sarcoidosis. The lung is the organ most commonly involved with sarcoidosis with at least 90 % of sarcoidosis patients demonstrating lung involvement in most series. The skin, eye, liver, and peripheral lymph node are the next most commonly clinically involved organs in most series, with the frequency of involvement ranging from 10 to 30 %. The actual frequency of sarcoidosis organ involvement is probably much higher as it is frequently asymptomatic and may avoid detection. This is particularly common with lung, liver, cardiac, and bone involvement. Cardiac sarcoidosis is present in 25 % of all sarcoidosis but only causes clinical problems in 5 % of them. Nevertheless, unlike sarcoidosis involvement of most other organs, it may be suddenly fatal. Therefore, it is important to screen for cardiac sarcoidosis in all sarcoidosis patients. All sarcoidosis patients should also be screened for eye involvement as asymptomatic patients may have eye involvement that may cause permanent vision impairment. Pulmonary fibrosis from sarcoidosis is usually slowly progressive but may be life-threatening because of the development of respiratory failure, pulmonary hypertension, or hemoptysis related to a mycetoma or bronchiectasis. Some manifestations of sarcoidosis are not organ-specific and probably are the result of a release of mediators from the sarcoid granuloma.

    Purpose of review Non-necrotizing granulomas in the affected organ are the hallmark of sarcoidosis. This review summarizes most recent genetic findings in sarcoidosis with a focus on genes that might influence granuloma formation or resolution. Specific results in multiple ethnic groups and certain clinical subphenotypes, such as extra-pulmonary organ involvement, are discussed. Recent findings Associations of genetic variants in antigen-presenting molecules (HLA-DRB1) were shown to confer risk to sarcoidosis and certain disease phenotypes in populations of different ethnic origin. Specific DRB1 alleles, such as *0301 and *0302, appear to confer protection against chronic disease, but in an ethnic-specific manner illustrating the extensive genetic heterogeneity and complexity at this locus. Mechanistic studies of putative sarcoid antigens lend further credence to a role of HLA-DRB1 in disease pathogenesis. With relevance to granuloma formation, genes involved in apoptotic processes and immune cell activation were further confirmed (ANXA11 and BTNL2) in multiple ethnicities; others were newly identified (XAF1). Linking mechanism to clinical application, a TNF variant was shown to correlate with anti-TNF response in sarcoidosis patients. Summary The investigation of known and novel risk variants for sarcoidosis and specific clinical phenotypes in various ethnicities highlights the genetic complexity of the disease. Detailed subanalysis of disease phenotypes revealed the potential for prediction of extra-pulmonary organ involvement and therapy response based on the patient's genotype. PMID:26164297

    Sarcoidosis is a multisystem disease characterized by non-caseating granulomas present in the involved organ systems. The disease is believed to result from an interaction among genetic factors, antigens, and the immune response. Environmental exposures and infectious agents have been implicated as potential causes. Cutaneous sarcoidosis presents clinically in many forms and the lesions are classified as either specific or non-specific. Non-specific lesions show a nondescript inflammatory process whereas specific lesions display typical, non-caseating granulomas. There are many different forms of specific lesions with some being more common than others. Psoriasiform lesions are uncommon. The literature suggests that as few as 0.9% of patients display this type of cutaneous sarcoidosis. Some of these patients present solely with cutaneous sarcoidosis, but others have systemic involvement with pulmonary involvement being the most common concomitant presentation. Plaques appear as round or oval, brownish, red infiltrated lesions, frequently involving the extensor surface of the extremities, face, scalp, back, and buttocks. Multiple configurations, including discrete, confluent, annular, and polycyclic, have been reported. Despite the clinical resemblance to psoriasis, on histological examination, only non-caseating granulomas are seen in the dermis. In rare cases both psoriasiform sarcoidosis and psoriasis were present.

    Introduction Sarcoidosis is a multisystemic, idiopathic disease. It has a highly variable clinical course. It has been reported to present in association with malignancy. Coexistence of sarcoidosis and thyroid cancer is rarely reported in the literature. Presentatioin of the case We present a case with neck swelling for 3 months, and symmetrical painless thyroid enlargement without fixation to deep tissues of the neck. Multiple nodules on the both thyroid lobes, hard irregular, grade two goiter with lymphadenopathy all over anterior neck compartments. Fine needle aspiration cytology was done under ultrasound guide from right thyroid nodule and showed papillary thyroid carcinoma. Excisional biopsy of the neck lymphnode showed picture typical for sarcoidosis. Discussion Most researchers believe that patients with pulmonary sarcoidosis are predisposed to develop malignancies, less than a dozen of cases are reported in the literature to be associated with PTC with a very wide range of presentations and clincal coarses. An interesting finding of our case is that in contrast to what is reported, both diseases were not known by the physician until the time of presentation. Conclusion Cervical lymphadenopathy in association with goiter could be metastasis, sarcoidosis or mixed, therefore should be seperately biopsied. PMID:26432997

    Sarcoidosis is a granulomatous disease of unknown etiology, most commonly involving the lung, skin, lymph node, and eyes. Molecular and immunologic studies continue to strengthen the association of sarcoidosis with infectious antigens. Independent studies report the presence of microbial nucleic acids and proteins within sarcoidosis specimens. Complementary immunologic studies also support the role of infectious agents in sarcoidosis pathogenesis. Case reports and clinical trials have emerged regarding the efficacy of antimicrobials. They support increasing efforts to identify novel therapeutics, such as antimicrobials, that will have an impact on the observed increase in sarcoidosis morbidity and mortality.

    Summary Sarcoidosis is a chronic multisystem disorder without any defined etiology. Cardiac sarcoidosis (CS) is detected in 2–7% of patients with sarcoidosis and more than 20% of the cases of sarcoidosis are clinically silent. Cardiac involvement in systemic sarcoidosis (SS) and isolated cardiac sarcoidosis (iCS) are associated with arrhythmia and severe heart failure (HF) and have a poor prognosis. Early diagnosis of CS and prompt initiation of corticosteroid therapy with or without other immunosuppressants is crucial. Electrocardiography, Holter monitoring, and Doppler echocardiography with speckle tracking imaging can serve as the initial steps to diagnosis of CS. Cardiac magnetic resonance (CMR) imaging and positron emission tomography (PET) are promising techniques for both diagnosis and follow-up of CS. This review discusses the main aspects of cardiac involvement in sarcoidosis. PMID:26668777

  8. Advances in the diagnosis and treatment of sarcoidosis

    PubMed Central

    2014-01-01

    This manuscript outlines recent advances in the diagnosis and treatment of sarcoidosis. The diagnosis of sarcoidosis can occasionally be made on clinical grounds without a confirmatory biopsy when very specific clinical findings are present. Otherwise, the diagnosis requires histologic evidence of granulomatous inflammation, exclusion of alternative causes, and evidence of systemic disease. Because there is no available diagnostic test for sarcoidosis, the diagnosis is never completely secure. Instruments have been developed to establish the presence of sarcoidosis in a second organ and hence establish the systemic nature of the disease. Corticosteroids remain the drug of choice for the treatment of sarcoidosis. Additional sarcoidosis medications are most commonly used as corticosteroid-sparing agents. Recent clinical sarcoidosis drug trials have exposed important issues that may confound trial results, including selecting patients with active disease, identifying study drug effects in patients receiving concomitant corticosteroids, and establishing proper study endpoints.

    A 59-year-old woman with skin sarcoidosis was admitted to hospital for assessment of complete atrioventricular block. Cross-sectional echocardiography showed that the apical free wall of the right ventricle was thin and dyskinetic with dilation of the right ventricle. Thallium-201 myocardial imaging revealed a normal distribution. Both gallium-67 and technetium-99m pyrophosphate scintigraphy revealed no abnormal uptake in the myocardium. Right ventriculography showed chamber dilation and dyskinesis of the apical free wall, whereas left ventriculography showed normokinesis, mimicking right ventricular dysplasia. Cardiac sarcoidosis was diagnosed on examination of an endomyocardial biopsy specimen from the right ventricle. A permanent pacemaker was implanted to manage the complete atrioventricular block. After steroid treatment, electrocardiography showed first-degree atrioventricular block and echocardiography revealed an improvement in the right ventricular chamber dilation. Reports of cardiac sarcoidosis mimicking right ventricular dysplasia are extremely rare and as this case shows, right ventricular involvement may be one of its manifestations.

    2013-01-01

    Sarcoidosis is a multisystem inflammatory disease of unknown etiology affecting multiple organs. Earlier reports suggested that sarcoidosis was a disease of the developed world. However, recent reports suggest that the disease is found in the developing countries as well. Clinical, radiological, and histopathological similarities with tuberculosis pose a great challenge in countries endemic for tuberculosis. Mantoux test, high resolution computed tomography, and transbronchial lymph node and lung biopsies are diagnostic modalities, which play an important role in the diagnosis of sarcoid. In this review, we look at the epidemiology of sarcoid in tuberculosis-endemic regions, the sarcoidosis-tuberculosis link, clinical profile, diagnostic modalities, dilemma in the diagnosis, and the treatment of this disease.

    The left ventricle (LV) is affected in 20-25% of patients with sarcoidosis and its involvement is associated with morbidity and mortality. However, effects of sarcoidosis on the right ventricle (RV) are not well documented. Our aims were to investigate the prevalence of RV dysfunction in patients with sarcoidosis and determine whether it is predominantly associated with direct cardiac involvement, severity of lung disease, or pulmonary hypertension (PH). We identified 50 patients with biopsy-proven extra-cardiac sarcoidosis and preserved LV function, who underwent echocardiography, pulmonary function (PF) testing, and cardiovascular magnetic resonance. RV function was quantified by free wall longitudinal strain. Tricuspid valve Doppler and estimated right atrial pressure were used to estimate systolic pulmonary artery pressure. Myocardial late gadolinium enhancement was considered diagnostic for cardiac sarcoidosis and assumed to involve both ventricles. Of the 50 patients, 28 (56%) had RV dysfunction, 4 with poorly defined PF status. Of the remaining 24 patients, 16 (67%) had lung disease, 8 (33%) had PH, and 10 (42%) had LV involvement. Ten patients had greater than one of these findings, and 4 had all 3. In contrast, in 4/24 patients (17%), RV dysfunction could not be explained by these mechanisms, despite severely reduced RV strain. In conclusion, RV dysfunction is common in patients with sarcoidosis and is usually associated with either direct LV involvement, lung disease, or PH, but may occur in the absence of these mechanisms, suggesting the possibility of isolated RV involvement and underscoring the need for imaging protocols that would include RV strain analysis.

    Clinically evident sarcoidosis involving the heart has been noted in at least 2 to 7% of patients with sarcoidosis, but occult involvement is much higher (> 20%). Cardiac sarcoidosis is often not recognized antemortem, as sudden death may be the presenting feature. Cardiac involvement may occur at any point during the course of sarcoidosis and may occur in the absence of pulmonary or systemic involvement. Sarcoidosis can involve any part of the heart, with protean manifestations. Prognosis of cardiac sarcoidosis is related to extent and site(s) of involvement. Most deaths due to cardiac sarcoidosis are due to arrhythmias or conduction defects, but granulomatous infiltration of the myocardium may be lethal. The definitive diagnosis of isolated cardiac sarcoidosis is difficult. The yield of endomyocardial biopsies is low; treatment of cardiac sarcoidosis is often warranted even in the absence of histologic proof. Radionuclide scans are integral to the diagnosis. Currently, 18F-fluorodeoxyglucose positron emission tomography/computed tomography and gadolinium-enhanced magnetic resonance imaging scans are the key imaging modalities to diagnose cardiac sarcoidosis. The prognosis of cardiac sarcoidosis is variable, but mortality rates of untreated cardiac sarcoidosis are high. Although randomized therapeutic trials have not been done, corticosteroids (alone or combined with additional immunosuppressive medications) remain the mainstay of treatment. Because of the potential for sudden cardiac death, implantable cardioverter-defibrillators should be placed in any patient with cardiac sarcoidosis and serious ventricular arrhythmias or heart block, and should be considered for cardiomyopathy. Cardiac transplantation is a viable option for patients with end-stage cardiac sarcoidosis refractory to medical therapy. PMID:25007089

    Whole-body PET scanning was performed using {sup 18}F-fluorodeoxyglucose (FDG) in two patients with hilar lymphadenopathy in whom the clinical differential diagnosis was between sarcoidosis and lymphoma. Both patients were later proven to have sarcoidosis. Uptake of {sup 18}FDG was seen in both intra- and extrathoracic lesions as well as in associated erythema nodosum. One patient underwent a repeat scan after steroid therapy where a marked decrease in hilar uptake was seen. Fluorine-18-fluorodeoxyglucose uptake is observed in lymph nodes with sarcoid involvement. Further investigation is necessary to assess if quantitative differences exist between sarcoid and malignant lymphadenopathy. 30 refs., 3 figs.

    Ocular or thermal burns account for 7.7%-18% of ocular trauma. The majority of victims are young. The burns occur in the setting of accidents at work or in the home, or during a physical attack. Chemical burns by strong acids or bases are responsible for the most serious injuries. Associated with the destruction of limbal stem cells, they present as recurrent epithelial ulcerations, chronic stromal ulcers, deep stromal revascularization, conjunctival overlap, or even corneal perforation. The initial clinical exam is sometimes difficult to perform in the presence of burning symptoms. Nevertheless, it enables the physician to classify the injury, establish a prognosis, and most importantly, guide the therapeutic management. The Roper-Hall modification of the Hughes classification system is the most widely utilized, broken down into stages based on the size of the stromal opacity and the extent of possible limbal ischemia. This classification is now favorably supplemented by those proposed by Dua and Wagoner, which are based on the extent of the limbal stem cell deficiency. The prognosis of the more serious forms of ocular burns has markedly improved over the last decade because of a better understanding of the physiology of the corneal epithelium. Surgical techniques aimed at restoring the destroyed limbal stem cells have altered the prognosis of severe corneal burns. In order to decrease the incidence of burns, prevention, particularly in industry, is essential. PMID:18971859

    Sarcoidosis is a systemic disease characterized by the development of noncaseating epithelioid granulomas in multiple organs. Despite extensive investigations over a long period of time, the etiology of this disease remains unknown. Cardiac involvement of this disease is the most ominous complication leading to fatal outcome. Recently, attention has been focused on isolated cardiac sarcoidosis, which exists without clinically apparent sarcoidosis elsewhere. One of the critical issues of isolated cardiac sarcoidosis is difficulty in diagnosis, since existence of the cardiac lesion should be detected from cardiac manifestations alone. Because specificity of biomarkers or sensitivity of histological examination of biopsied sample is very low, diagnosis of isolated cardiac sarcoidosis mainly depends on imaging modalities. In this review article we summarized current knowledge on the pathogenesis of sarcoidosis, clinical features of cardiac sarcoidosis especially that isolated to the heart by showing some typical cases. Utilities and problems of diagnostic imaging tests for this condition including echocardiography, cardiac magnetic resonance imaging, and fluorodeoxyglucose-positron emission tomography are discussed. Advances in pharmacological and nonpharmacological treatment for cardiac sarcoidosis have improved the prognosis of cardiac sarcoidosis to a great deal; however, there are many issues that remain to be solved in the management of isolated cardiac sarcoidosis.

    Sarcoidosis is a granulomatous disease that mainly affects the lungs and intrathoracic lymph nodes; however, virtually any organ can be affected. As an orphan disease, recommendations are mainly based on observational or small randomized studies as well as experts' opinion. Diagnosing sarcoidosis requires proof of non-necrotizing granulomas in patients with a compatible symptomatic pattern and the exclusion of other granulomatous diseases. Granulomas can be detected best in the lungs or intrathoracic lymph nodes. Therefore, bronchoscopy and endobronchial ultrasound with biopsies of lymph nodes are the major tools to diagnose sarcoidosis. Frequently, close follow-up and symptomatic therapy are sufficient to allow for spontaneous resolution. In case of functional organ impairment, cardial or CNS involvement, or other complications, steroid therapy is necessary with a starting dose of 0.5 mg/kg body weight that should be tapered-off over 6-12 months. Steroid-refractory disease can be treated by adding methotrexate or azathioprine, two drugs long known in sarcoidosis treatment. Monoclonal antibodies against TNF and lung transplantation are further therapeutic options.

    Sarcoidosis involving the gastrointestinal tract is extremely rare. Clinically recognizable gastrointestinal system involvement occurs in 0.1% to 0.9% of patients with sarcoidosis. We encountered a 22-year-old African American female admitted to Johns Hopkins Hospital (Baltimore, Maryland) for a 2-week history of fever, chills, eye pain, and abdominal pain. Her abdominal CT scan showed multiple subcentimeter retroperitoneal lymph nodes. An upper endoscopy was performed and discovered an antral nodule that measured about 7 mm and antral gastritis in which biopsies showed active chronic necrotizing granulomatous gastritis. Biopsies of the antral polyp showed focal intestinal metaplasia and active chronic necrotizing granulomatous pattern. Stains for Helicobacter pylori, acid fast, and fungi were negative. A small-bowel series showed no abnormality. Ophthalmologic evaluation revealed panuveitis with bilateral optic disc edema. The patient was later prescribed 60 mg of prednisone by mouth once a day and subsequently her abdominal pain and fever resolved during follow-up 2 months later. This literature review demonstrates the importance in the diagnosis, pathophysiology, clinical manifestations, types of gastric sarcoidosis, major endoscopic findings, and management of gastric sarcoidosis.

    Sarcoidosis is a systemic granulomatous disease predominantly affecting the lungs. It is believed to be caused by exposure to pathogenic antigens in genetically susceptible individuals but the causative antigen has not been identified. The formation of non-caseating granulomas at sites of ongoing inflammation is the key feature of the disease. Other aspects of the pathogenesis are peripheral T-cell anergy and disease progression to fibrosis. Many T-cell-associated cytokines have been implicated in the immunopathogenesis of sarcoidosis, but it is becoming apparent that IL-12 cytokine family members including IL-12, IL-23, IL-27, and IL-35 are also involved. Although the members of this unique cytokine family are heterodimers of similar subunits, their biological functions are very diverse. Whilst IL-23 and IL-12 are pro-inflammatory regulators of Th1 and Th17 responses, IL-27 is bidirectional for inflammation and the most recent family member IL-35 is inhibitory. This review will discuss the current understanding of etiology and immunopathogenesis of sarcoidosis with a specific focus on the bidirectional impact of IL-12 family cytokines on the pathogenesis of sarcoidosis.

    There are dermatological symptoms in up to 25% of patients with sarcoidosis, and the appearance of specific subcutaneous nodules as a manifestation of this entity is rare. They may even predate other manifestations of sarcoidosis. We present the case of a 38-year-old woman with asymptomatic subcutaneous nodules in the limbs, which corresponded to deep sarcoid granulomas in the histological study. She did not present with any extracutaneous indications. The imaging tests performed revealed right paratracheal adenopathies. This led to the diagnosis of sarcoidosis, in both its subcutaneous and pulmonary forms (stage I). Subcutaneous sarcoidosis is probably an underdiagnosed entity, as fewer than 40 cases are reflected in literature. Its value lies in the fact that it may be the first manifestation of extracutaneous or systemic sarcoidosis, which means that this form of sarcoidosis must be considered in the differential diagnosis of subcutaneous nodular lesions; close follow-up of these patients is also necessary.

    Spectrally resolved white-light interferometry (SRWLI) was used to measure the wavelength dependence of refractive index (i.e., dispersion) for various ocular components. The accuracy of the technique was assessed by measurement of fused silica and water, the refractive indices of which have been measured at several different wavelengths. The dispersion of bovine and rabbit aqueous and vitreous humor was measured from 400 to 1100 nm. Also, the dispersion was measured from 400 to 700 nm for aqueous and vitreous humor extracted from goat and rhesus monkey eyes. For the humors, the dispersion did not deviate significantly from water. In an additional experiment, the dispersion of aqueous and vitreous humor that had aged up to a month was compared to freshly harvested material. No difference was found between the fresh and aged media. An unsuccessful attempt was also made to use the technique for dispersion measurement of bovine cornea and lens. Future refinement may allow measurement of the dispersion of cornea and lens across the entire visible and near-infrared wavelength band. The principles of white- light interferometry including image analysis, measurement accuracy, and limitations of the technique, are discussed. In addition, alternate techniques and previous measurements of ocular dispersion are reviewed.

    Several case reports deal with the relationship between hepatitis C virus (HCV) infection and pulmonary or hepatic sarcoidosis. Most publications describe interferon α-induced sarcoidosis. However, HCV infection per se is also suggested to cause sarcoidosis. The present case report describes a case of biopsy-verified lung and liver sarcoidosis and HCV infection, and the outcome of antiviral therapy. In March 2009, a 25-year-old man presented with moderately elevated liver enzymes without any clinical symptoms. The patient was positive for HCV antibodies and HCV RNA of genotype 1b. Four months later the patient became dyspnoic and pulmonary sarcoidosis was diagnosed by lung biopsy and radiography. A short course of corticosteroid treatment relieved symptoms. Three months later, liver biopsy showed noncaseating granulomas consisting of epithelioid histiocytes and giant cells with a small amount of peripheral lymphocyte infiltration, without any signs of fibrosis. Chronic HCV infection with coexistence of pulmonary and hepatic sarcoidosis was diagnosed. Antiviral therapy with peginterferon α and ribavirin at standard doses was started, which lasted 48 wk, and sustained viral response was achieved. A second liver biopsy showed disappearance of granulomas and chest radiography revealed normalization of mediastinal and perihilar glands. The hypothesis that HCV infection per se may have triggered systemic sarcoidosis was proposed. Successful treatment of HCV infection led to continuous remission of pulmonary and hepatic sarcoidosis. Further studies are required to understand the relationship between systemic sarcoidosis and HCV infection. PMID:23155326

    Of the glomerulonephritis associated with sarcoidosis, membranous nephropathy (MN) is the most prevalent. Coincidence or a causal relationship between these two diseases is unclear. Here, we present for the first time a high prevalence of PLA2R-related MN among patients with MN associated with active sarcoidosis. Our results suggest some causal link between sarcoidosis and PLA2R-related MN. Detection of anti-PLA2R antibodies in serum or PLA2R antigen in biopsy should not be taken as evidence against a secondary cause, particularly sarcoidosis. This important observation can affect treatment decision in these patients.

    The treatment of sarcoidosis is not standardized. Because sarcoidosis may never cause significant symptoms or organ dysfunction, treatment is not mandatory. When treatment is indicated, oral corticosteroids are usually recommended because they are highly likely to be effective in a relative short period of time. However, because sarcoidosis is often a chronic condition, long-term treatment with corticosteroids may cause significant toxicity. Therefore, corticosteroid sparing agents are often indicated in patients requiring chronic therapy. This review outlines the indications for treatment, corticosteroid treatment, and corticosteroid sparing treatments for sarcoidosis. PMID:23596348

These lesions were biopsied and the histological examination indicated sarcoidosis. The patient had a history of headache and syncope that lasted for about 1 h. Brain CT showed masses measuring 37×20 mm in both frontal lobes. Thoracic and abdominal CT showed many pathologically enlarged lymph nodes. The patient was diagnosed with cutaneous, lung and neuronal sarcoidosis, and treated with 20 mg/day methylprednisolone, 15 mg/week methotrexate, 10 mg/week folic acid, 400 mg/day hydroxychloroquine and 800 mg/day carbamazepine. One month later, the patient's neurological symptoms had improved and her skin lesions had decreased. At 6-month follow-up, the size of the cranial masses had markedly regressed.

    A female patient suffering from the ulcerative form of skin sarcoidosis is described and the literature dealing with this problem is reviewed. Peculiar features of this case are described: ulceration of the nodes, which is an extremely rare phenomenon; no involvement of other organs, lungs included, was detectable, which is not typical of ulcerative sarcoidosis; small-nodular elements are parallelled by nodes (Boeck's small-nodular sarcoid and Darier-Roussy's subcutaneous sarcoids) in this patient, this evidencing an uniform pathologic process in the skin and subcutaneous fat. Ulceration in this patient is explained by the development of allergic vasculitis of the immediate hypersensitivity type (leukocytoclastic vasculitis and manifest increase of the level of circulating immune complexes). Prednisolone therapy has resulted in an excellent clinical effect.

    A case of sarcoidosis limited to the central nervous system is described in which the diagnosis was suggested by high Ga-67 uptake in the cranial and spinal meninges. The diagnosis was confirmed by meningeal biopsy. Treatment with oral corticosteroids resulted in clinical improvement and marked reduction in Ga-67 uptake in the meninges. This is the first reported case of the central nervous system sarcoid diagnosed by Ga-67 imaging.

    Susceptibility to most human diseases is polygenic, with complex interactions between functional polymorphisms of single genes governing disease incidence, phenotype, or both. In this context, the contribution of any discrete gene is generally modest for a single individual, but may confer substantial attributable risk on a population level. Environmental exposure can modify the effects of a polymorphism, either by providing a necessary substrate for development of human disease or because the effects of a given exposure modulate the effects of the gene. In several diseases, genetic polymorphisms have been shown to be context-dependent, i.e. the effects of a genetic variant are realized only in the setting of a relevant exposure. Since sarcoidosis susceptibility is dependent on both genetic and environmental modifiers, the study of gene-environment interactions may yield important pathogenetic information and will likely be crucial for uncovering the range of genetic susceptibility loci. However, the complexity of these relationships implies that investigations of gene-environment interactions will require the study of large cohorts with carefully-defined exposures and similar clinical phenotypes. A general principle is that the study of gene-environment interactions requires a sample size at least several-fold greater than for either factor alone. To date, the presence of environmental modifiers has been demonstrated for one sarcoidosis susceptibility locus, HLA-DQB1, in African-American families. This article reviews general considerations obtaining for the study of gene-environment interactions in sarcoidosis. It also describes the limited current understanding of the role of environmental influences on sarcoidosis susceptibility genes. PMID:17560304

    In an effort to detect extrapulmonary sites of radiogallium accumulation in cases of sarcoidosis, 145 separate Ga-67 citrate studies of 114 patients with biopsy-proven sarcoidosis were examined. The most characteristic extrapulmonary radiogallium uptake pattern was the panda sign in 47 patients (41%). The most common site of prominent extrapulmonary radiogallium uptake was the lacrimal glands in 101 patients (88%). Second most common was activity in one or more superficial lymph node regions such as the cervical, axillary, femoral, or inguinal in 19 patients (17%). Other extrapulmonary sites included breast uptake in 6 out of 80 women (8%), prominent splenic and nasal uptake in 9 (8%) patients, periportal accumulation in 7 (6%), and cutaneous/subcutaneous activity in 4 (4%). Because many of these individuals were receiving corticosteroids, the natural (untreated) prevalence of extrapulmonary findings may be even higher. Although the sensitivity and specificity of extrapulmonary radiogallium accumulation has still to be determined, many of the sites may be accessible to biopsy both for diagnostic purposes and to follow the effects of medications. It is therefore suggested that whole-body imaging be performed when radiogallium is administered to patients with suspected or known sarcoidosis.

    Gastrointestinal sarcoidosis is a rare disease with very limited data in children. Here we report the first pediatric case of successful treatment with infliximab. The first case was an 8-year-old Saudi girl who presented with fever, weight loss, and abdominal pain that was followed in a few months with hematemesis and development of hepatosplenomegaly. The second case was a 9-year-old Sudanese boy who manifested with vomiting, epigastric pain, and weight loss. On upper endoscopy, both cases demonstrated severe erosive nodular gastric mucosa. Gastric and esophageal biopsies had shown noncaseating granulomatous inflammation. The first case had histopathological evidence of granulomatous hepatitis, and both cases demonstrated lung nodularity on computed tomography chest. The boy had elevated angiotensin-converting enzyme level. Given the multisystem involvement with significant chest findings, tissue findings of granulomatous disease, and negative workup for other causes of granulomatous inflammation, both cases were diagnosed with active disseminated sarcoidosis, and treated with corticosteroids. The girl continued to be symptom-free for 4 years after tapering steroid therapy. The boy had relapses off steroids and the disease was brought into remission for 5 years off steroid therapy by infliximab. Pediatric GI sarcoidosis is a rare disease that exhibits heterogeneity in natural course. The chronic relapsing progressive form of the disease might benefit from infliximab therapy. PMID:27748327

    Sarcoidosis is a granulomatous disease of unknown cause. This proteiform disease is characterized by an almost constant and often predominant lung involvement. The natural history of disease is difficult to predict at presentation. Diagnosis is based on a compatible clinical and radiological presentation and evidence of non-caseating granulomas. Exclusion of alternative diseases is also required according to clinical presentation. Biopsy samples of superficial lesions should be considered before other sites like per-endoscopic bronchial biopsies or endobronchial ultrasound-guided transbronchial needle aspiration. Therapeutic strategy for lung disease has to take into account the possible spontaneous resolution observed in newly diagnosed patients. Corticosteroids are the first choice when a treatment is decided, which concerns half of patients. Second and third line therapy are based respectively on immunosuppressive drugs and anti-TNFα drugs. Sarcoidosis mortality and morbidity are mainly linked to advanced pulmonary sarcoidosis - lung fibrosis, pulmonary hypertension, bronchial stenosis and chronic pulmonary aspergillosis. "Non anti-inflammatory" treatments have to be considered as well. Clinicians have an essential role in treatment indication, end-point targets and evaluation of response to treatment during follow-up and in finding the best benefice to risk balance. Progress made on pharmacogenetics may offer more personalized treatments for the patients. PMID:26897112

Because lesions assume a vast array of morphologies, a classification dividing them into specific (with presence of typical granulomas in the biopsy) or nonspecific (not containing granulomas) has been proposed. In the first group the variant morpheaform is considered exceptional. We review the cases reported in the literature and describe the possible differential diagnosis. We highlight the importance of recognizing the very atypical presentation of sarcoidosis and its ability to mimic morpheaform or sclerosis diseases in our patients. PMID:27084558

    Abstract The association between cancer and sarcoidosis is controversial. Some epidemiological studies show an increase of the incidence of cancer in patients with sarcoidosis but only few cases of sarcoidosis following cancer treatment have been reported. We conducted a retrospective case study from internal medicine and oncology departments for patients presenting sarcoidosis after solid cancer treatment. We also performed a literature review to search for patients who developed sarcoidosis after solid cancer. We describe the clinical, biological, and radiological characteristics and outcome of these patients. Twelve patients were included in our study. Various cancers were observed with a predominance of breast cancer. Development of sarcoidosis appeared in the 3 years following cancer and was asymptomatic in half of the patients. The disease was frequently identified after a follow-up positron emission tomography computerized tomography evaluation. Various manifestations were observed but all patients presented lymph node involvement. Half of the patients required systemic therapy. With a median follow-up of 73 months, no patient developed cancer relapse. Review of the literature identified 61 other patients for which the characteristics of both solid cancer and sarcoidosis were similar to those observed in our series. This report demonstrates that sarcoidosis must be considered in the differential diagnosis of patients with a history of malignancy who have developed lymphadenopathy or other lesions on positron emission tomography computerized tomography. Histological confirmation of cancer relapse is mandatory in order to avoid unjustified treatments. This association should be consider as a protective factor against cancer relapse. PMID:26181571

    Sarcoidosis is a systemic granulomatous disease that affects numerous organs, commonly manifesting at the lungs and skin. While corticosteroids remain the first line of treatment, tumour necrosis factor alpha (TNF-α) inhibitors have been investigated as one potential steroid sparing treatment for sarcoidosis. TNF-α is one of many components involved in the formation of granulomas in sarcoidosis. While there have been larger scale studies of biologic TNF-α inhibition in systemic sarcoidosis, studies in cutaneous disease are limited. Paradoxically, in some patients treated with biologic TNF-α inhibitors for other diseases, treatment can induce the development of sarcoidosis. In the light of this complexity, we discuss the role of TNF-α in granuloma formation, the therapeutic role of TNF-α inhibition and immunologic abnormalities following treatment with these TNF-α inhibitors including drug-specific alterations involving interferon-γ, lymphotoxin-α, TNF receptor 2 (TNFR2) and T-regulatory cells.

    Assessment of gallium-67 ({sup 67}Ga) uptake in the salivary and lacrimal glands and intrathoracic lymph nodes was made in 605 consecutive patients including 65 with sarcoidosis. A distinctive intrathoracic lymph node {sup 67}Ga uptake pattern, resembling the Greek letter lambda, was observed only in sarcoidosis (72%). Symmetrical lacrimal gland and parotid gland {sup 67}Ga uptake (panda appearance) was noted in 79% of sarcoidosis patients. A simultaneous lambda and panda pattern (62%) or a panda appearance with radiographic bilateral, symmetrical, hilar lymphadenopathy (6%) was present only in sarcoidosis patients. The presence of either of these patterns was particularly prevalent in roentgen Stages I (80%) or II (74%). We conclude that simultaneous (a) lambda and panda images, or (b) a panda image with bilateral symmetrical hilar lymphadenopathy on chest X-ray represent distinctive patterns which are highly specific for sarcoidosis, and may obviate the need for invasive diagnostic procedures.

    Cardiac sarcoidosis is an infiltrative, granulomatous inflammatory disease of the myocardium. Generally, it can be difficult to diagnose cardiac sarcoidosis clinically because of the non-specific nature of its clinical manifestations. This property can be based on the presence of any clinical evidence of sarcoidosis in the other organs. We present two cases of cardiac sarcoidosis so as to demonstrate its different clinical manifestations. The first patient displayed no cardiac symptoms; the electrocardiogram showed an incidental right bundle branch block. Her cardiac magnetic resonance imaging (CMRI) revealed late-phase opaque material enhancement involving the inferior and inferoseptal segment of the left ventricle. The second patient was severely symptomatic in terms of cardiac involvement, and a transthoracic echocardiogram revealed global hypokinesia and septal brightness; his ejection fraction decreased to 45%. These cases highlighted the challenges encountered in the diagnosis and treatment of cardiac sarcoidosis. CMRI should be considered in all patients who have suspected findings for cardiac involvement.

    This is the first case report of acute sarcoidosis with increased serum thymidine kinase (TK) activity. A 43-year-old male presented fever, swelling of parotid glands, lymphadenopathy, and peripheral neuropathy. Sarcoidosis was pathologically diagnosed by lung and parotid gland biopsy. His serum TK, which was increased to 11.2 U/l at diagnosis (normal <5 U/l), normalized after glucocorticoid therapy. Serum TK has been considered as a good marker of the proliferative activity of various types of neoplasms. Its rise in sarcoidosis has, however, not been described. Because acute sarcoidosis sometimes resembles malignant lymphoma, the possible rise of serum TK in sarcoidosis may be worthy of note. PMID:11868600

    Chronic beryllium disease (CBD) is a granulomatous lung disease that may be pathologically and clinically indistinguishable from pulmonary sarcoidosis, except through use of immunologic testing, such as the beryllium lymphocyte proliferation test (BeLPT). Similar to sarcoidosis, the pulmonary manifestations of CBD are variable and overlap with other respiratory diseases. Definitive diagnosis of CBD is established by evidence of immune sensitization to beryllium and diagnostic bronchoscopy with bronchoalveolar lavage and transbronchial biopsy. However, the diagnosis of CBD can also be established on a medically probable basis in beryllium-exposed patients with consistent radiographic imaging and clinical course. Beryllium workers exposed too much higher levels of beryllium in the past demonstrated a much more fulminant disease than is usually seen today. Some extrapulmonary manifestations similar to sarcoidosis were noted in these historic cohorts, although with a narrower spectrum. Extrapulmonary manifestations of CBD are rare today. Since lung-predominant sarcoidosis can very closely resemble CBD, CBD is still misdiagnosed as sarcoidosis when current or past exposure to beryllium is not recognized and no BeLPT is obtained. This article describes the similarities and differences between CBD and sarcoidosis, including clinical and diagnostic features that can help physicians consider CBD in patients with apparent lung-predominant sarcoidosis.

    Sarcoidosis is a systemic granulomatous disease of undetermined etiology in which the immune system is overstimulated. Management of the patient with sarcoidosis entails continuity of patient care far beyond disease, even into remission. Care is comprehensive, including all involved organ systems, coordination of specialty consultations and services, and includes diagnostic tests. Therapeutic decisions are the responsibility of the primary care practitioner. Prognosis of sarcoidosis is not uniformly good. Patients can die. Subacute sarcoidosis patients usually do not require pharmacologic therapy. Chronic sarcoidosis may require long-term treatment for years to indefinitely. Corticosteroids are still the drugs of choice and other therapy is now available. Health organizations and private nonprofit support groups are available for patient education and assistance. Close support must still come from the family unit. Sarcoidosis may occur in family members in different cohorts at all ages in life and in any racial or ethnic group. The second in a two-part series on management of the patient with sarcoidosis, this article describes coordination of care and considers community, prevention, and family aspects of the disease.

    Sarcoidosis is a systemic granulomatous disease of unknown etiology. Granulomatous inflammation in sarcoidosis may affect multiple organs, including the lungs, skin, CNS, and the eyes, leading to severe morbidity and mortality. The underlying mechanisms for sustained inflammation in sarcoidosis are unknown. We hypothesized that metabolic changes play a critical role in perpetuation of inflammation in sarcoidosis. 1H nuclear magnetic resonance (NMR)-based untargeted metabolomic analysis was used to identify circulating molecules in serum to discriminate sarcoidosis patients from healthy controls. Principal component analyses (PCA) were performed to identify different metabolic markers and explore the changes of associated biochemical pathways. Using Chenomx 7.6 NMR Suite software, we identified and quantified metabolites responsible for such separation in the PCA models. Quantitative analysis showed that the levels of metabolites, such as 3-hydroxybutyrate, acetoacetate, carnitine, cystine, homocysteine, pyruvate, and trimethylamine N-oxide were significantly increased in sarcoidosis patients. Interestingly, succinate, a major intermediate metabolite involved in the tricyclic acid cycle was significantly decreased in sarcoidosis patients. Application of integrative pathway analyses identified deregulation of butanoate, ketone bodies, citric cycle metabolisms, and transmethylation. This may be used for development of new drugs or nutritional modification. PMID:27489531

    Sarcoidosis is a systemic disorder of unknown aetiology characterised by its pathological hallmark of non-caseating granuloma. Definitive diagnosis requires compatible clinical and imaging features as well as pathogenic identification of non-caseating granulomas in at least one organ. The disease has a wide variety of clinical and radiological manifestations but is associated with low mortality. However, cardiac involvement which is clinically only identified in 5% significantly worsens prognosis due to complications such as congestive heart failure, ventricular tachyarrhythmia, pulmonary hypertension or conduction disturbance leading to sudden death. Cardiac involvement is implicated in 77-85% of deaths directly related to sarcoidosis. Autopsy series in sarcoidosis patients show cardiac involvement with sarcoidosis in up to 79% cases. This case details the clinical course of a 56-year-old female who had experienced refractory cardiac dysrhythmias for many years in the context of also having biopsy proven pulmonary sarcoidosis. She had failed multiple antiarrhythmics as well as pacemaker and implantable cardioverter defibrillator placement. It was not until she presented as a potentially fatal ventricular tachycardia that the possibility of cardiac involvement from her sarcoidosis was entertained as the aetiology of her cardiac problems. Confirmation of myocardial sarcoidosis with PET CT imaging and subsequent treatment with prednisone resulted in her clinical improvement.

    Sarcoidosis is a multisystem granulomatous disease of unknown origin. All organs may be affected. Liver involvement is common but it is rarely symptomatic. Only a few cases of Budd-Chiari syndrome (BCS) secondary to a hepatic sarcoidosis have been described so far. We describe a case of multisystemic sarcoidosis presenting with BCS. A 42-year old female was referred to our department for chronic and anicteric cholestasis. Laboratory and imaging investigations disclosed features of chronic BCS associated with multisystemic sarcoidosis. The positive diagnosis was based on microscopic features, which showed hepatic, gastric and cutaneous non-caseating granulomas. Screening for an underlying thrombophilic disorder was negative. The diagnosis of BCS complicating hepatic sarcoidosis was the most likely. She was put on corticosteroids and anticoagulation therapy. To our knowledge, few cases of sarcoidosis-related BCS have been reported in the literature. In addition to being an uncommon presentation of sarcoidosis, this case illustrates the importance of recognizing an unusual cause of BCS and its therapeutic difficulties. PMID:26900444

The frequency of signs or symptoms of hepatic involvement is very low. Case Report We present a case of symptomatic granulomatous liver disease secondary to sarcoidosis, mimicking a metastatic disease on ultrasonography and CT. Conclusions Hepatic involvement in sarcoidosis might be a perplexing diagnostic problem. The decisive CT finding with respect to the differential diagnosis was the absence of a mass effect and intact vascular architecture around the lesions. PMID:25908950

    ABSTRACT We present a patient with Cushing disease apparently suppressing sarcoidosis, which was unmasked following surgical resection of a pituitary adrenocorticotropin (ACTH)-producing microadenoma. Case report and a short review of the literature published in this area. A 46-year-old Caucasian woman presented with symptoms of hypercortisolism such as progressive weight gain, Cushingoid appearance, proximal myopathy, easy bruising, and amenorrhea. Blood testing including inferior petrosal sinus sampling uncovered an ACTH-producing microadenoma in the right aspect of the anterior pituitary gland for which the patient underwent transphenoidal resection. Maintenance corticosteroid therapy was implemented, and the signs and symptoms of Cushing disease began to resolve. Three months after surgery, multiple erythematous painful nodules developed on the patient's arms. Erythema nodosum (EN) was diagnosed clinically and a suspicion of underlying sarcoidosis was substantiated by lung imaging and elevated plasma interleukin (IL)-2 receptor. One month later, the lesions spontaneously resolved without therapy other than maintenance glucocorticoid replacement. Physicians should be aware that patients undergoing successful treatment of Cushing syndrome may have a flare-up or emergence of a corticosteroid-responsive disease. PMID:27375832

    Objective: To identify and follow a series of 52 patients with optic neuropathy related to sarcoidosis. Methods: Prospective observational cohort study. Results: The disorder was more common in women and affected a wide age range. It was proportionately more common in African and Caribbean ethnic groups. Two clinical subtypes were identified: the more common was a subacute optic neuropathy resembling optic neuritis; a more slowly progressive optic neuropathy arose in the remaining 17%. Sixteen (31%) were bilateral. Concurrent intraocular inflammation was seen in 36%. Pain arose in only 27% of cases. An optic perineuritis was seen in 2 cases, and predominate involvement of the chiasm in one. MRI findings showed optic nerve involvement in 75% of cases, with adjacent and more widespread inflammation in 31%. Treatment with corticosteroids was helpful in those with an inflammatory optic neuropathy, but not those with mass lesions. Relapse of visual signs arose in 25% of cases, necessitating an increase or escalation of treatment, but relapse was not a poor prognostic factor. Conclusions: This is a large prospective study of the clinical characteristics and outcome of treatment in optic neuropathy associated with sarcoidosis. Patients who experience an inflammatory optic neuropathy respond to treatment but may relapse. Those with infiltrative or progressive optic neuropathies improve less well even though the inflammatory disorder responds to therapy. PMID:27536707

    We present a patient with Cushing disease apparently suppressing sarcoidosis, which was unmasked following surgical resection of a pituitary adrenocorticotropin (ACTH)-producing microadenoma. Case report and a short review of the literature published in this area. A 46-year-old Caucasian woman presented with symptoms of hypercortisolism such as progressive weight gain, Cushingoid appearance, proximal myopathy, easy bruising, and amenorrhea. Blood testing including inferior petrosal sinus sampling uncovered an ACTH-producing microadenoma in the right aspect of the anterior pituitary gland for which the patient underwent transphenoidal resection. Maintenance corticosteroid therapy was implemented, and the signs and symptoms of Cushing disease began to resolve. Three months after surgery, multiple erythematous painful nodules developed on the patient's arms. Erythema nodosum (EN) was diagnosed clinically and a suspicion of underlying sarcoidosis was substantiated by lung imaging and elevated plasma interleukin (IL)-2 receptor. One month later, the lesions spontaneously resolved without therapy other than maintenance glucocorticoid replacement. Physicians should be aware that patients undergoing successful treatment of Cushing syndrome may have a flare-up or emergence of a corticosteroid-responsive disease. PMID:27375832

    Sarcoidosis is a systemic granulomatous disease of unknown aetiology. The frequency of cardiac involvement (cardiac sarcoidosis (CS)) varies in the different geographical regions, but it has been reported that it is an absolutely important prognostic factor in this disease. Complete atrioventricular block is the most common, and ventricular tachycardia/ventricular fibrillation the second most common arrhythmia in this disease, both of which are associated with cardiac sudden death. Diagnosing CS is sometimes difficult because of the non-specific ECG and echocardiographic findings, and CS is sometimes misdiagnosed as dilated cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy or an idiopathic ventricular aneurysm, and therefore, endomyocardial biopsy is important, but has a low sensitivity. Another problem is the recognition of isolated types of CS. Recently, MRI and (18)F-fluorodeoxyglucose positron emission tomography have been demonstrated to be useful tools for the non-invasive diagnosis of CS as well as therapeutic evaluation tools, but are still unsatisfactory. Treatment of CS is usually done by corticosteroid therapy to control inflammation, prevent fibrosis and protect from any deterioration of the cardiac function, but the long-term outcome is still in debate. Despite the advancement of non-pharmacological approaches for CS (pacing, defibrillators and catheter ablation) to improve the prognosis, there are still many issues remaining to resolve diagnosing and managing CS. Here, we attempt a review of the clinical evidence, with special focus on the current understanding of this disease and showing the current strategies and remaining problems of diagnosing and managing CS.

    The liver is one of the most commonly involved extrapulmonary sites in sarcoidosis. Hepatic sarcoidosis has a broad range of presentations from scattered, asymptomatic noncaseating granulomas with normal liver enzymes, which are very common in patients with known pulmonary sarcoidosis, to portal hypertension and cirrhosis, which are relatively uncommon. Diagnosis is based on a combination of clinical, laboratory and histological manifestations. The authors' protocol for management of patients with suspected sarcoidosis of the liver without focal lesions includes a transjugular liver biopsy with portal pressure measurements to confirm the diagnosis, rule out coexisting liver diseases and to identify select patients with fibrosis or portal hypertension for consideration of immunosuppression. Steroids and azathioprine are the preferred agents and methotrexate is not recommended.

    Propionibacterium acnes has been repeatedly suggested as a candidate causative agent of sarcoidosis. It is the only microorganism that has been isolated from sarcoid lesions by bacterial culture so far and this has been described in Japanese patients only. We report two non-Japanese patients in whom mediastinoscopy was performed in order to obtain lymph node tissue for histopathology, which was suggestive for sarcoidosis. Bacterial culture of these uncontaminated mediastinal lymph nodes revealed P. acnes in both patients. As shown in these two cases, P. acnes can be isolated from sterile biopsied sarcoid lymph nodes of non-Japanese patients and supports the belief that there is an etiologic link between P. acnes sarcoidosis. Further elucidation could provide an opening to novel strategies using antibiotics for treating sarcoidosis.

Incidence of masses due to Sarcoidosis in upper extremity is low and most cases present in association with involvement of pulmonary hilary lymph nodes. In this article we present a rare case of Sarcoidosis which presented as a single soft tissue mass in hand without osseous or pulmonary hillary lymph node involvement. Incidence of involvement of musculoskeletal system is 1-5 %, mostly it occurs in small bones in hands and feet. In most cases involvement of soft tissue in extremities is accompanied with bone lesions. Those cases of soft tissue involvement are generally coincide with pulmonary lymph nodules. To the authors` knowledge, this is the first case of Sarcoidosis that presents without spreading in bones or pulmonary hilar lymph nodes. PMID:26894226

The evidence linking sarcoidosis with environmental triggers such as metals is increasing. We describe the case of a 44 year old female with a history. of smoking since age 30 and previous mercury dental filling who presented at physical examination with numerous subcutaneous nodules. Laboratory data showed accelerated erythrocyte sedimentation rate and high titer of anti-U1 ribonucleoprotein antibodies (U1 RNP). Skin biopsy and chest X-ray suggested the diagnosis of sarcoidosis. In this report we illustrate the different causes involved in the onset of sarcoidosis. PMID:27228643

    Association between sarcoidosis and antiphospholipid syndrome (APS) is rare with few reported cases. We sought to systematically review the published cases of APS with sarcoidosis to better characterize the demographics, clinical characteristics, treatment, and the outcome of this association. Systematic electronic search for case report, case series, and related articles published until May 2014 was carried out and relevant data were extracted and analyzed. Four cases of APS with sarcoidosis were identified exclusively in females. These cases were seen in the sixth decade of life. Pulmonary embolism and central retinal artery occlusion were the presenting thrombotic events. All the patients were treated with lifelong anticoagulation with warfarin. During the median follow-up period of 5.5 months, additional thrombotic events were not observed. Although rare, sarcoidosis may be associated with APS. Further reporting of the cases will help to better establish this association, elucidate pathogenesis, and define clinical characteristics and outcomes. PMID:26605200

    Double-labelling immunofluorescence analysis within the CD4+ cell subset was carried out in 27 bronchoalveolar lavage fluids and 11 peripheral blood samples of sarcoidosis patients with anti-TQ1, anti-2H4 and anti-4B4 monoclonal antibodies. Helper/inducer CD4+TQ1-/4B4+ cells were strongly increased in the lung and slightly, but significantly, decreased in the blood of sarcoidosis patients with respect to normal controls. No differences were found in the number of both lung and blood CD4+2H4+ cells between sarcoidosis patients and controls. The findings are further evidence for a compartmentalization of T cell subsets in sarcoidosis. PMID:3263230

    Hepatic sarcoidosis is usually asymptomatic but rarely leads to adverse liver-related outcome. Co-existence of viral hepatitis and hepatic sarcoidosis is a rare, but recognised phenomenon. Obtaining a balance between immune suppression and anti-viral therapy may be problematic. Immunosuppression in the presence of viral hepatitis can lead to rapid deterioration of liver disease. Similarly, anti-viral therapy may exacerbate granulomatous hepatitis. Here we present two cases of viral hepatitis co-existing with sarcoidosis that illustrate successful management strategies. In one, hepatitis B replication was suppressed with oral anti-viral therapy before commencing prednisolone. In the second, remission of hepatic sarcoidosis was achieved with prednisolone, before treating hepatitis C and obtaining a sustained virological response with pegylated interferon and ribavirin therapy.

    We explored the relationship between erythema nodosum (EN) and sex, age, serum angiotensin converting enzyme (ACE), bronchoalveolar lavage lymphocytosis (BAL-I), interstitial granulomas and radiological stage in patients presenting with pulmonary sarcoidosis in Ireland. Sixty-nine patients diagnosed with sarcoidosis between 2003 and 2006 were studied. Forty one patients (59%) were male. Sixteen patients (23%) presented with EN. Forty one patients of 65 (63%) had transbronchial biopsies demonstrating non-caseating granulomas. Patients with sarcoidosis presenting with EN were more likely to be female (p=0.042), younger (p=0.012) and have earlier stage pulmonary disease (p=0.02). There were no correlations between serum ACE, interstitial granulomas and disease stage. BAL-I did however predict increasing disease radiological stage (p=0.042). In this study, one quarter of patients with sarcoidosis presented with EN among their presenting features. These patients were more likely to be young females with early stage radiological disease.

    Cutaneous lesions are a part of common manifestation in multi-systemic sarcoidosis and skin involvement occurs in 20% to 35% of the patients with systemic disease. An exclusive cutaneous involvement is rare and it is reported in about 4%-5% of the patients of sarcoidosis. These lesions have been classified into specific and non-specific, depending on the presence of non- caseating granulomas, on histopathologic studies. In the present study, we are reporting two cases of isolated cutaneous sarcoidosis without systemic manifestations, which is a rare presentation. Sarcoidosis will continue to challenge even the most experienced clinicians with respect to a high degree of suspicion and further investigations for diagnosing and treating this disorder.

    Sarcoidosis is a disease with reported familial clustering, but a putative hereditary component has not been established. We analyzed 33 sarcoid index cases with a positive family history and their 596 1st and 2nd degree relatives to determine if the distribution of disease was consistent with a genetic etiology. Prevalence of sarcoidosis was twice as high in 1st degree relatives of index cases compared to 2nd degree relatives (8.5% vs. 3.9%; p=0.016). Recurrence risk ratios (defined as the risk of disease in relatives divided by the population prevalence) were calculated in 2nd degree relatives after making an ascertainment correction. A single gene model fit the observed results better than a polygenic model for a range of sarcoidosis prevalance. A greater shared environment among siblings compared to parents and offspring did not appear to increase risk of sarcoidosis based on a higher prevalance of disease in the latter (7.1% vs. 10.7%; p=0.313). However, the age of diagnosis in affected parent-offspring pairs was more consistent with a combined genetic and environmental etiology than either component alone. In summary, these results suggest a genetic component, possibly a single gene, increases disease risk in family members of sarcoidosis cases. A segregation analysis is planned to more thoroughly evaluate the evidence for both genetic and non-genetic transmission of sarcoidosis in these families.

    Roentgenograms and gallium-67 scans and gallium-67 counts of BAL fluid samples, together with differential cell counts, have proved to be useful in assessing activity and lung involvement in sarcoidosis. In active pulmonary sarcoidosis gallium-67 scans are usually positive. Quantitation of gallium-67 uptake in lung scans, however, may be difficult. Because gallium-67 uptake and cell counts in BAL fluid may be correlated, we set out to investigate gallium-67 activity in BAL fluid recovered from patient of different groups. Sixteen patients with recently diagnosed and untreated sarcoidosis, nine patients with healthy lungs, and five patients with CFA were studied. Gallium-67 uptake of the lung, gallium-67 activity in the lavage fluid, SACE and LACE levels, and alpha 1-AT activity were measured. Significantly more gallium-67 activity was found in BAL fluid from sarcoidosis patients than in that from CFA patients (alpha = .001) or patients with healthy lungs (alpha = .001). Gallium-67 activity in BAL fluid could be well correlated with the number of lymphocytes in BAL fluid, but poorly with the number of macrophages. Subjects with increased levels of SACE or serum alpha 1-AT showed higher lavage gallium-67 activity than did normals, but no correlation could be established. High gallium-67 activity in lavage fluid may be correlated with acute sarcoidosis or physiological deterioration; low activity denotes change for the better. The results show that gallium-67 counts in BAL fluid reflects the intensity of gallium-67 uptake and thus of activity of pulmonary sarcoidosis.

    Sarcoidosis is a multi-system disease pathologically characterized by the accumulation of T-lymphocytes and mononuclear phagocytes into the sine qua non pathologic structure of the noncaseating granuloma. Cardiac involvement remains a key source of morbidity and mortality in sarcoidosis. Definitive diagnosis of cardiac sarcoidosis, particularly early enough in the disease course to provide maximal therapeutic impact, has proven a particularly difficult challenge. However, major advancements in imaging techniques have been made in the last decade. Advancements in imaging modalities including echocardiography, nuclear spectroscopy, positron emission tomography, and magnetic resonance imaging all have improved our ability to diagnose cardiac sarcoidosis, and in many cases to provide a more accurate prognosis and thus targeted therapy. Likewise, therapy for cardiac sarcoidosis is beginning to advance past a “steroids-only” approach, as novel immunosuppressant agents provide effective steroid-sparing options. The following focused review will provide a brief discussion of the epidemiology and clinical presentation of cardiac sarcoidosis followed by a discussion of up-to-date imaging modalities employed in its assessment and therapeutic approaches.

    Sarcoidosis is typically characterized as a non-caseating granulomatous disease that has the ability to affect multiple different organ systems. Although extra-thoracic sarcoidosis can occur in the presence and also without lung involvement, isolated extra-pulmonary disease is rare. The liver is the third most commonly affected organ system after the lungs and lymph nodes. When discussing hepatic sarcoidosis it is important to keep in mind that many patients in this population may not present as one would typically expect since most of the patients are asymptomatic or have mild presentations. Therefore, the diagnosis can be difficult at times since no single laboratory or imaging study can definitively diagnose this systemic disease. In the rare case of some patients where there is difficulty in discerning between different pathologies, the use of image-guided tissue biopsy may be necessary to establish a diagnosis. At the current time, there are no clear guidelines for the management of hepatic sarcoidosis and are mostly dependent on a patient's clinical status at time of presentation. The current body of research in regard to treatment suggests steroids to be the mainstay of therapy. However, there is a role for additional immunosuppressive therapy in cases where the initial treatment is refractory to steroids. In this manuscript, we discussed the pathogenesis of liver sarcoidosis and context of its presentation. In addition, the differential diagnosis and imaging evaluation in this population is discussed. Finally, treatment options are reviewed in setting of previous studies for liver sarcoidosis. PMID:27175775

    Sarcoidosis is a systemic disease characterized by noncaseating granulomatous inflammation with tremendous clinical heterogeneity and uncertain pathobiology and lacking in clinically useful biomarkers. The Genomic Research in Alpha-1 Antitrypsin Deficiency and Sarcoidosis (GRADS) study is an observational cohort study designed to explore the role of the lung microbiome and genome in these two diseases. This article describes the design and rationale for the GRADS study sarcoidosis protocol. The study addresses the hypothesis that distinct patterns in the lung microbiome are characteristic of sarcoidosis phenotypes and are reflected in changes in systemic inflammatory responses as measured by peripheral blood changes in gene transcription. The goal is to enroll 400 participants, with a minimum of 35 in each of 9 clinical phenotype subgroups prioritized by their clinical relevance to understanding of the pathobiology and clinical heterogeneity of sarcoidosis. Participants with a confirmed diagnosis of sarcoidosis undergo a baseline visit with self-administered questionnaires, chest computed tomography, pulmonary function tests, and blood and urine testing. A research or clinical bronchoscopy with a research bronchoalveolar lavage will be performed to obtain samples for genomic and microbiome analyses. Comparisons will be made by blood genomic analysis and with clinical phenotypic variables. A 6-month follow-up visit is planned to assess each participant’s clinical course. By the use of an integrative approach to the analysis of the microbiome and genome in selected clinical phenotypes, the GRADS study is powerfully positioned to inform and direct studies on the pathobiology of sarcoidosis, identify diagnostic or prognostic biomarkers, and provide novel molecular phenotypes that could lead to improved personalized approaches to therapy for sarcoidosis.

    2009-02-01

    Pulmonary fibrosis is an unusual "end stage" in patients with sarcoidosis. Fibrosis occurs in a minority of patients, and presents with a unique physiologic combination of airways dysfunction (obstruction) superimposed on the more common restrictive dysfunction. Imagin techniques are essential to the diagnosis, assessment and treatment of pulmonary fibrosis. Standard chest radiographs and CT scans may reveal streaks, bullae, cephalad retraction of the hilar areas, deviation of the trachea and tented diaphragm. Positive gallium and PET scans indicate residual reversible granulomatous disease and are important guides to therapy decisions. Treatment, usually with corticosteroids, is effective in those patients with positive scans, but fibrosis does not improve with any treatment. With severe functional impariment and patient disability, pulmonary hypertension and right heart failure may supervene for which the patient will require treatment. Oxygen, careful diuresis, sildenafil and bosentan may be salutary. These patients are candidates for lung transplantation. PMID:19170216

    Sarcoidosis is a common multisystem granulomatous condition of unknown aetiology, predominantly involving the respiratory system. Tracheal stenosis has been described but we believe that we present the first case of a tracheo-oesophageal fistula secondary to chronic sarcoidosis. A 57-year-old woman with sarcoidosis, a known tracheal stricture and a Polyflex(®) stent in situ presented with stridor. Bronchoscopy confirmed in-stent stenosis, by exuberant granulation tissue. The stent was removed and the granulation tissue was resected accordingly. Postoperatively, the patient was noticed to have an incessant cough and video fluoroscopy raised the suspicion of a tracheo-oesophageal fistula. A repeat bronchoscopy demonstrated marked granulation tissue, accompanied by a fistulous connection with the oesophagus at the mid-lower [middle of the lower] third of the trachea. Three Polyflex(®) stents were sited across the entire length of the trachea. Sarcoidosis presents with varying clinical manifestations and disease progression. Tracheal involvement appears to be a rare phenomenon and usually results in stenosis. To date, there has been little or no documented literature describing the formation of a tracheo-oesophageal fistula resulting from sarcoidosis. Early reports documented the presence of sarcoidosis induced weakening in the tracheal wall, a process termed tracheal dystonia. Weaknesses are more apparent in the membranous aspect of the trachea. Despite the rare nature of such pathology, this case report highlights the need to consider the presence of a tracheo-oesophageal fistula in sarcoidosis patients presenting with repeat aspiration in the absence of an alternate pathology.

    OBJECTIVE: To determine the frequency of and the factors related to delayed diagnosis of sarcoidosis in Brazil. METHODS: We evaluated patients with a biopsy-proven diagnosis of sarcoidosis, using a questionnaire that addressed the following: time since symptom onset and since the first medical visit; and the number and specialty of the physicians visited. We divided the patients by the timeliness of the diagnosis-timely (< 6 months) and delayed (≥ 6 months)-comparing the two groups in terms of systemic and pulmonary symptoms; extrathoracic involvement; spirometric data; radiological staging; level of education; income; and tuberculosis (diagnosis and treatment). RESULTS: We evaluated 100 patients. The median number of physicians consulted was 3 (range, 1-14). In 11 cases, sarcoidosis was diagnosed at the first visit. In 54, the first physician seen was a general practitioner. The diagnosis of sarcoidosis was timely in 41 patients and delayed in 59. The groups did not differ in terms of gender; race; type of health insurance; level of education; income; respiratory/systemic symptoms; extrathoracic involvement; and radiological staging. In the delayed diagnosis group, FVC was lower (80.3 ± 20.4% vs. 90.5 ± 17.1%; p = 0.010), as was FEV1 (77.3 ± 19.9% vs. 86.4 ± 19.5%; p = 0.024), misdiagnosis with and treatment for tuberculosis (≥ 3 months) also being more common (24% vs. 7%, p = 0.032, and 20% vs. 0%; p = 0.002, respectively). CONCLUSIONS: The diagnosis of sarcoidosis is often delayed, even when the imaging is suggestive of sarcoidosis. Delayed diagnosis is associated with impaired lung function at the time of diagnosis. Many sarcoidosis patients are misdiagnosed with and treated for tuberculosis. PMID:24310626

    Sarcoidosis is a systemic granulomatous disease characterized by the presence of non-caseating granulomas. Its etiology remains obscure. A plausible hypothesis suggests that a complex interplay of host factors, infectious processes, and non-infectious environmental factors, matched with a susceptible genetic background, results in a pathway that leads to systemic granulomatous inflammation. Although presentations of sarcoidosis vary enormously, multi-organ involvement is a common feature. Cutaneous involvement occurs in about 25% of patients with protean manifestations and variable prognoses. Skin manifestations are divided into specific lesions with histopathologically evident non-caseating granulomas and nonspecific lesions arising from a reactive process that does not form granulomas. A peculiar form of cutaneous sarcoidosis is represented by sarcoidal lesions at sites of trauma that has caused scarring. The pathogenesis of scar sarcoidosis remains unknown. Scar sarcoidosis is also associated with herpes zoster infection, surgery, and tattooing. Such heterogeneous events, along with those at the sites of chronic lymphedema, thermal burns, radiation dermatitis, and vaccinations, occur on areas of vulnerable skin labeled "immunocompromised districts". Numerous options are available for the treatment of cutaneous sarcoidosis. Although corticosteroids remain the treatment of choice for initial systemic therapy, other nonsteroidal agents have proven effective and therefore useful for long-term management. Tumor necrosis factor-α antagonists such as infliximab may have a role in the treatment of cutaneous sarcoidosis, especially in refractory cases that are resistant to standard regimens. Elucidation of the relationship of sarcoidal granulomas with malignancy and immunity may facilitate a better understanding of some pathomechanisms operating in neoplastic and immunity-related disorders.

    Sarcoidosis is a multisystem chronic inflammatory condition of unknown etiology that has the potential to involve every tissue in the body. Sarcoidosis in the gastrointestinal system, and particularly the colon, is very rare. Here, we report the case of a 57-year-old man with no previous diagnosis of sarcoidosis who presented with new onset of abdominal pain and constipation. A colonoscopy revealed that the abdominal pain was caused by an obstructing lesion in the cecum-ascending colon and lacked a clear histologic diagnosis. Radiologic investigation revealed concentric wall thickening of the cecum-ascending colon with multiple satellite lymphadenopathies, highly suggestive of a malignancy. The patient underwent a laparotomy and a right hemicolectomy was performed. A diagnosis of colonic sarcoidosis was made after the resected specimen was examined. Additionally, a chest computed tomography scan revealed lung involvement with atypical radiologic features in the absence of respiratory symptoms. Only histologic examination of the surgical specimen can yield a diagnosis of gastrointestinal sarcoidosis due to the non-specificity of endoscopic and radiologic findings.

    Subcutaneous sarcoidosis (also known as 'Darier-Roussy sarcoid') is a cutaneous condition characterized by numerous deep-seated nodules on the trunk and extremities. Coexistence of sarcoidosis and breast cancer are reported in the literature, but there will always be a chance of misdiagnosis. It is very crucial to obtain a tissue diagnosis of suspicious metastatic lesions. We report a case of breast cancer presenting with a subcutaneous sarcoid lesion masquerading as a metastatic lesion. A 50-year-old female patient, who had had cancer of the left breast, was on hormone therapy 2 years after treatment with surgery, radiotherapy and chemotherapy. The patient presented with a sudden onset of a forehead subcutaneous swelling mimicking metastasis which on excision biopsy was proved to be sarcoidosis. In India, sarcoidosis is reported rarely. We have to keep in mind that there is a chance of the metastatic lesions being of sarcoidosis origin or another granulomatous disease. To avoid misdiagnosis, it is better to obtain a tissue diagnosis. PMID:20737045

    The diagnostic accuracy achieved by taking bronchial mucosal and lung biopsies through flexible fiberoptic bronchoscopes was compared with scalene lymph node biopsy in 55 patients with sarcoidosis. The diagnostic yield with flexible fiberoptic bronchoscopy was 62 per cent in the whole material and increased to 76 per cent in patients with stage II sarcoidosis. Scalene lymph node biopsy was positive in 80 per cent. Flexible fiberoptic bronchoscopy is a useful method for obtaining biopsy material in sarcoidosis, especially in stage II sarcoidosis. We consider flexible fiberoptic bronchoscopy and scalene lymph node biopsy the methods of choice in the diagnosis of sarcoidosis. PMID:6628338

    Sarcoidosis is a systemic granulomatous disorder of unknown origin commonly affecting the lung, the lymphoid system and the skin. We report here two cases of cutaneous sarcoidosis in two former intravenous drug users following interferon (IFN)-α and ribavirin therapy for chronic hepatitis C. Both patients developed skin sarcoidosis along venous drainage lines of both forearms, coinciding with the areas of prior drug injections. The unique distribution of the skin lesions suggests that tissue damage induced by repeated percutaneous drug injections represents a trigger for the local skin manifestation of sarcoidosis. Interestingly, skin damage was recently found to induce the local expression IFN-α, a well-known trigger of sarcoidosis in predisposed individuals. Here we review the literature on sarcoidosis elicited in the context of IFN-α therapy and propose a new link between the endogenous expression of IFN-α and the induction of disease manifestations in injured skin.

    Sarcoidosis is a granulomatous disease that most frequently affects the lungs with pulmonary infiltrates and/or bilateral hilar and mediastinal lymphadenopathy. An association of sarcoidosis and lymphoproliferative disease has previously been reported as the sarcoidosis-lymphoma syndrome. Although this syndrome is characterized by sarcoidosis preceding lymphoma, very few cases of sarcoidosis following lymphoma have been reported. We describe the clinical, biological, and radiological characteristics and outcome of 39 patients presenting with sarcoidosis following lymphoproliferative disease, including 14 previously unreported cases and 25 additional patients, after performing a literature review. Hodgkin lymphoma and non-Hodgkin lymphoma were equally represented. The median delay between lymphoma and sarcoidosis was 18 months. Only 16 patients (41%) required treatment. Sarcoidosis was of mild intensity or self-healing in most cases, and overall clinical response to sarcoidosis was excellent with complete clinical response in 91% of patients. Sarcoidosis was identified after a follow-up computerized tomography scan (CT-scan) or fluorodeoxyglucose-positron emission tomography/computerized tomography (FDG-PET/CT) evaluation in 18/34 patients (53%). Sarcoidosis is therefore a differential diagnosis to consider when lymphoma relapse is suspected on a CT-scan or FDG-PET/CT, emphasizing the necessity to rely on histological confirmation of lymphoma relapse.

    Sarcoidosis is an inflammatory systemic disease that may present in many different ways. The pathophysiological mechanisms are not still well known, although sarcoidosis results from an exaggerated Th1 immune response. About 30% of sarcoidosis patients may suffer from skin lesions during the course of the disease and, occasionally, psoriasiform lesions have been observed. Sarcoidosis may present associated with other diseases and psoriasis is actually one of them, even though not particularly frequent. Few cases of patients who showed clinical and histological features compatible with both pulmonary sarcoidosis and psoriasis vulgaris have been reported. We report an interesting case of a patient affected by sarcoidosis at the onset of psoriasis and discuss immunopathogenetic mechanisms that can be associated with these conditions. Recent data confirm that sarcoidosis is a Th1/Th17 multisystem disorder. These clarifications may be helpful in the management of the diseases and in identifying patients at risk.

    Sarcoidosis is a chronic disorder that can virtually affect any organ system in the body. Histologically, it is characterized by the presence of T lymphocytes, mononuclear phagocytes, and noncaseating granulomas. Most commonly affected are the intrathoracic structures, with 90% of the reported cases involving the lungs. Esophageal involvement in sarcoidosis is extremely rare. Dysphagia is the most common presentation in these patients and can be attributed to various mechanisms such as direct esophageal wall infiltration, extrinsic compression, cranial neuropathy, and brainstem involvement. A thorough online literature review revealed only 23 reported cases of esophageal involvement in sarcoidosis. This paper reviews these reported cases in detail along with newer diagnostic and treatment options, including direction of future therapy. PMID:23533794

    A female patient presented with asymptomatic swellings in old blue-black tattoo marks of her forearms. On careful skin examination, few raised erythematous, circular plaques were also found on the non-tattooed skin on her back, about which she was unaware. The diagnosis of cutaneous and systemic sarcoidosis was confirmed after classical histopathological findings from skin lesions from her non tattooed back and from papulonodular tattooed lesions, ruling out other causes of granulomas and supported by a negative Mantoux test, raised serum angiotensin converting enzyme level, high resolution computed tomography thorax, etc. She responded well to oral steroid therapy. The importance of a careful skin examination, easy access provided by skin lesions in suspected cases of cutaneous/systemic sarcoidosis, the value of sudden tattoo changes in the diagnosis here and the possible contribution of tattoos toward the causation of cutaneous and/or systemic sarcoidosis are highlighted.

    Sarcoidosis is a systemic inflammatory disorder characterised by tissue infiltration by mononuclear phagocytes and lymphocytes with associated non-caseating granuloma formation. Originally described as a disorder of the skin, sarcoidosis can involve any organ with wide-ranging clinical manifestations and disease course. Recent studies have provided new insights into the mechanisms involved in disease pathobiology, and we now know that sarcoidosis has a clear genetic basis largely involving human leukocyte antigen (HLA) genes. In contrast to Mendelian-monogenic disorders--which are generally due to specific and relatively rare mutations often leading to a single amino acid change in an encoded protein--sarcoidosis results from genetic variations relatively common in the general population and involving multiple genes, each contributing an effect of varying magnitude. However, an individual may have the necessary genetic profile and yet the disease will not develop unless an environmental or infectious factor is encountered. Genetics appears also to contribute to the huge variability in clinical phenotype and disease behaviour. Moreover, it has been established that sarcoidosis granulomatous inflammation is a highly polarized T helper 1 immune response that starts with an antigenic stimulus followed by T cell activation via a classic HLA class II-mediated pathway. A complex network of lymphocytes, macrophages, and cytokines is pivotal in the orchestration and evolution of the granulomatous process. Despite these advances, the aetiology of sarcoidosis remains elusive and its pathogenesis incompletely understood. As such, there is an urgent need for a better understanding of disease pathogenesis, which hopefully will translate into the development of truly effective therapies. PMID:25791751

    The incidence and clinical features of sarcoidosis were studied in a retrospective survey of 156 patients attending two South London hospitals between 1969 and 1982. Sixty-eight patients were Caucasian, 59 were Black West Indian or African immigrants and 29 were immigrants racially derived from Indo-Pakistan (Asians). The annual incidence of sarcoidosis in the local community in 1977-78 was 19.8 per 10(5) for Blacks and 16.8 per 10(5) for Asians compared with 1.5 per 10(5) for Caucasians. Erythema nodosum was a more common presenting feature in Caucasians than in Blacks (P less than 0.001) or Asians (P less than 0.05). Blacks developed sarcoidosis at a later age than Caucasians (P less than 0.05) and were less likely to present as a chance finding on a chest radiograph (P less than 0.05). They had more widespread extrathoracic disease than Caucasians (P less than 0.001) and were more commonly treated with corticosteroids (P less than 0.001). In the Asians there was a male predominance compared with Caucasians (P less than 0.01). Asians also had more extrathoracic sarcoidosis than Caucasians (P less than 0.001) and more of them were treated with corticosteroids (P less than 0.05). A stage 2 chest radiograph at presentation (P less than 0.05) and skin sarcoidosis (P less than 0.05) were less common in Asians than in Blacks, but otherwise there were no significant differences between the two groups. In this study the incidence of sarcoidosis in Asians approached that in Blacks, while the clinical features were intermediate in severity between Blacks and Caucasians. In both Blacks and Asians the disease was more common, more severe and more extensive than in Caucasians.

    A method of direct quantitation of /sup 67/Ga uptake in the lung is described. The attenuation coefficient requires calculation and is obtained simply for each patient by transmission using a planar radionuclide source. The validity of the method was tested with a phantom (error less than 10%). Forty-three patients with pulmonary and/or mediastinal sarcoidosis were classified. The different groups of patients as defined clinically and radiographically (controls, nonactive, and active sarcoidosis) were well-differentiated (p less than 0.001).

    Sarcoidosis is a multisystem disorder that is characterized by noncaseous epithelioid cell granulomas, which may affect almost any organ. Thoracic involvement is common and accounts for most of the morbidity and mortality associated with this disease. The diagnosis is based on exhaustive exclusion of differential diagnoses, particularly granulomatous infections. We report data on eight patients with paracoccidioidomycosis mimicking sarcoidosis. Five patients presented with a chronic pulmonary type infection and three had a disseminated form after immunosuppressive treatment. The mycological diagnosis in noncaseating granulomas is emphasized and reviewed.

    The application of radioisotope scanning to osseous involvement from systemic sarcoidosis has been infrequently described in the scientific literature. Most commonly, the small bones of the hands and feet are affected if sarcoidosis involves the skeleton. Nonetheless, there are also occasional manifestations of sarcoid in the skull, long bones, and vertebral bodies. This paper describes a case of sarcoid involving the lung parenchyma with multiple lesions in the skull and ribs demonstrated by bone scanning with Tc-99m MDP. Following treatment with steroids, the bone scan showed complete resolution of the rib lesions and almost complete resolution of the lesions in the calvarium.

    Sarcoidosis is a multisystem granulomatous disorder with a high prevalence of cardiac involvement. Cardiac sarcoidosis (CS) may be life threatening due to end-stage cardiomyopathy and sudden cardiac death. The frequent absence of specific symptoms and lack of a diagnostic 'gold standard' pose challenges in the diagnosis of CS. Endomyocardial biopsy, although specific, has an unacceptably low sensitivity. Non-invasive cardiac imaging has a huge role in the assessment of patients with known or suspected CS. This comprehensive review compares the diagnostic accuracy, along with advantages and disadvantages, of established and emerging imaging modalities for CS.

    Angiotensin-converting enzyme is used as a marker for sarcoid activity. We describe a case of remission of cutaneous and lymphatic sarcoidosis in a patient treated with an ACE inhibitor for congestive heart failure and hypertension; the remission has continued over 4 years of follow-up. Because this is a report of only one case, there is a possibility of sampling error. Whether the patient's remission in this case was a serendipitous spontaneous remission that happened to occur during ACE inhibitor therapy or whether ACE inhibitor therapy can play a role in the treatment of sarcoidosis needs to be determined in a large clinical trial.

    A 10-year-old female was diagnosed as having early-onset sarcoidosis (EOS) after a prolonged skin disease. A granuloma emerged on the face at age 2 and massive lesions extended to the rest of the body. Repeated biopsies indicated histiocytic proliferation. At age 7, fever, disseminated macular eruptions, and multinucleated giant cells in the bone marrow prompted vinblastine and prednisolone therapy. Five months after stopping therapy, hypercalcemic crisis occurred along with fever, cytopenias, and interferon-gamma-nemia indicating a macrophage activation syndrome. A biopsy of nodules confirmed the diagnosis of sarcoidosis. The atypical EOS should be differentiated from histiocytosis.

    Sarcoidosis is a systemic granulomatous disease with a wide range of clinical manifestations. Skin involvement is an early, frequent and accessible location for a histopathological study. Several risk factors have been described to determine the likelihood of systemic involvement of an apparent cutaneous condition. Early diagnosis and systemic treatment could prevent future complications. A series of three cases is presented in which the initial diagnosis was cutaneous sarcoidosis, but it was actually the first manifestation of a systemic disease. A review of this topic is also presented. PMID:25823568

    As the driving population ages, the number of drivers with visual impairment resulting from ocular disease will increase given the age-related prevalence of ocular disease. The increase in visual impairment in the driving population has a number of implications for driving outcomes. This review summarises current research regarding the impact of common ocular diseases on driving ability and safety, with particular focus on cataract, glaucoma, age-related macular degeneration, hemianopia and diabetic retinopathy. The evidence considered includes self-reported driving outcomes, driving performance (on-road and simulator-based) and various motor vehicle crash indices. Collectively, this review demonstrates that driving ability and safety are negatively affected by ocular disease; however, further research is needed in this area. Older drivers with ocular disease need to be aware of the negative consequences of their ocular condition and in the case where treatment options are available, encouraged to seek these earlier for optimum driving safety and quality of life benefits.

    Environmental microbial assays of industrial microscope eyepieces were conducted following reports of multiple intershift ocular infections. Pathogenic Staphylococcus aureus was identified among the microorganisms cultured. This paper suggests that direct contact with industrial microscope eyepieces provides a potentially significant route of transmission of both bacterial and viral ocular infections. An industrial hygiene ocular health questionnaire was distributed to a first and second shift manufacturing operation to assess the incidence of ocular infections. These data were compared to the questionnaire responses of 122 control manufacturing workers who did not use microscopes. Based on self-reporting by employees, those who used microscopes were found to have statistically significant incidence of sites and conjunctivitis that was 8.3 times that of the control group. Sterilization of eyepieces by ethylene oxide, formaldehyde and isopropyl alcohol were considered, but ultimately rejected. These biocides were found respectively to damage ocular lens coatings, contribute to volatile organic emissions, or be ineffective against spore-forming bacteria. This article presents a detailed evaluation of a commercially available ultraviolet sanitization unit (manufactured by the King Bactostat Corp., 7115 Armistad Street, El Paso, TX 79912). This ultraviolet disinfection process proved to be rapid and emission free; it also yielded eyepieces free of residual chemical biocides that have the potential for ocular irritation. Field tests involving 60 eyepieces demonstrated effective disinfection by a Chi-Square statistical comparison, at values greater than 95% confidence level, as compared to unirradiated eyepieces.

    2014-01-01

    Sarcoidosis is a chronic systemic disease of unknown etiology that is characterized by the presence of noncaseating epithelioid granulomas, usually in multiple organs. Several studies have shown that sarcoidosis might be the result of an exaggerated granulomatous reaction after exposure to unidentified antigens in genetically susceptible individuals. Cardiac involvement may occur and lead to an adverse outcome: the heart mechanics will be affected and that causes ventricular failure, and the cardiac electrical system will be disrupted and lead to third degree atrioventricular block, malignant ventricular tachycardia, and sudden cardiac death. Thus, early diagnosis and treatment of this potentially devastating disease is critically important. However, sensitive and accurate imaging modalities have not been established. Recent studies have demonstrated the promising potential of cardiac magnetic resonance imaging (MRI) and 18F-fluoro-2-deoxyglucose positron emission tomography (18F-FDG PET) in the diagnosis and assessment of cardiac sarcoidosis (CS). In this review, we discuss the epidemiology, etiology, histological findings, and clinical features of sarcoidosis. We also introduce advanced imaging including 18F-FDG PET and cardiac MRI as more reliable diagnostic modalities for CS. PMID:25250336

    The sarcoidosis is a systemic granulomatosis affecting most frequently the lungs and the mediastinum. An acute renal failure reveals exceptionally this disease. It's a retrospective study implicating 12 cases of sarcoidosis complicated of acute renal failure. The aim of this study is to determine epidemiological, clinical, biological and histological profile in these cases and then to indicate the interest to consider the diagnosis of sarcoidosis in cases of unexplained renal failure. Extra-renal complications, therapeutic modalities and the outcome were determined in all patients. Our series involved 12 women with an average age of 40 years. Biological investigations showed an abnormal normocalcemia in 7 cases, a hypercalcemia in 5 cases, a hypercalciuria in 10 cases and polyclonal hypergammaglobulinemia in 7 cases. An acute renal failure was found in all patients with a median creatinin of 520 umol/L. For all patients, the renal echography was normal however, the kidney biopsy showed tubulo-interstitial nephritis. The extra-renal signs highlighting pulmonary interstitial syndrome in 5 cases, a sicca syndrome in 4 cases, mediastinal lymph nodes in 2 cases, a lymphocytic alveolitis in 3 cases, an anterior granulomatous uveitis in 2 cases and a polyarthritis in 5 cases. Five patients benefited of hemodialysis. The treatment consisted of corticosteroid in all cases. The follow up was marked by complete resolution of clinical and biological signs. The diagnosis of renal sarcoidosis must be done quickly to prevent renal failure.

    OBJECTIVES: The possibility of an association between exposure to silica and autoimmune diseases has recently come under discussion. In the following case-referent study, a cohort exposed to diatomaceous earth and cristobalite provided an opportunity to evaluate such an exposure with reference to sarcoidosis. METHODS: The inhabitants of a district served by a single healthcare centre and a hospital formed the study base. A diatomaceous earth plant is located in this community and the medical institutions are responsible for primary and secondary health care of the population. Cases of sarcoidosis were identified from the hospital records according to certain clinical, radiological, and histological criteria. Referents were selected randomly from the population of the district. Information on exposure to crystalline silica, cristobalite, was obtained by record linkage of the cases and referents with a file which included all present and past workers at the diatomaceous earth plant and those who had worked at loading vessels with the product from the plant. RESULTS: Eight cases of sarcoidosis were found, six of which were in the exposed group. Of the 70 referents, 13 were exposed. The odds ratio (95% confidence interval) was 13.2 (2.0 to 140.9). CONCLUSION: The odds ratios were high and there were some indications of a dose-response relation which will hopefully encourage further studies. To our knowledge this is the first study to indicate a relation between sarcoidosis and exposure to the crystalline silica, cristobalite.   PMID:9930085

    Pulmonary sarcoidosis is reported to have complication of lymphoproliferative disease such as malignant lymphoma, but the complication of multicentric Castleman's disease (MCD) is rarely reported. In our case of a 60-year-old woman, bilateral hilar lymphadenopathy was noted in her chest X-ray. We performed a transbronchial lung biopsy. She was diagnosed as having pulmonary sarcoidosis (Stage II). The shadow on chest X-ray disappeared without treatment. However, after 8 years, swelling of the mediastinal and abdominal lymph node, thickened bronchovascular bundle, and multiple nodular shadows were identified, and a thoracoscopic lung biopsy was performed. Based on the histopathological findings and elevated serum interleukin-6 level (75.7 pg/mL), she was diagnosed with pulmonary sarcoidosis complicated by MCD. When a change in chest X-ray findings are found during monitoring of pulmonary sarcoidosis, it is important to proceed with a thoracoscopic lung biopsy, because of the possibility of the rare complication of MCD.

The rarity of the situation prompted us to report this patient who was a 51-year-old woman with a 2-years history of breathlessness, cough with expectoration, chest pain and backache. Initial evaluation revealed mild anemia, increased alkaline phosphatase with chest skiagram showing both lower zone non homogenous opacities with calcified hilar lymph nodes. CECT chest showed mediastinal with bilateral hilar lymphadenopathy, parenchymal fibrosis, traction bronchiectasis, ground glass opacities, septal and peribronchovascular thickening affecting mid and lower lung zones bilaterally. MRI Dorsolumbar spine was suggestive of marrow infiltrative disorder. EBUS FNA of intrathoracic nodes, EBB and TBLB confirmed sarcoidosis. PET CT revealed hyper metabolic activity in lung, multiple lymph nodes and lytic bone lesions. Serum protein electrophoresis and immunofixation revealed a monoclonal paraprotein, immunoglobulin IgG kappa type. Bone marrow biopsy revealed an increase in plasma cells (15%), but no granulomas. Diagnosis of Indolent or multiple myeloma with sarcoidosis was established. 12 cases of sarcoidosis and multiple myeloma have been reported in literature, and mostly preceding the onset of multiple myeloma by many years, in our case both were diagnosed concurrently.

    To update current knowledge on the pathology and etiology of sarcoidosis, here we review previous epidemiological research and discuss age-related differences and historical changes in the clinical characteristics of sarcoidosis we identified over the last four decades in Japan. Extrathoracic lymph node involvement was more common in young patients, while extrathoracic involvement of non-lymphatic organs and hypercalcemia were more common in older patients. Most patients in their 20s presented with bilateral hilar lymphadenopathy, but this was consistently less common among older patients. Over time, the distribution of age at diagnosis has shifted toward the older age group in the United States, Denmark, and Japan. In Japan, the incidence rate has been decreasing among young people, but there has consistently been a second peak among postmenopausal women. Age-related differences in the clinical presentation of sarcoidosis may reflect the pathways of causative antigens and the strengthening of immunoregulatory mechanisms with age. Internal and external environmental factors, such as exposure to diverse microorganisms, ovarian insufficiency, and active vitamin D deficiency, that may contribute to the onset of sarcoidosis must be identified in order to develop strategies for prevention and treatment.

    Background Pulmonary hypertension (PH) is a rare complication of sarcoidosis, although it is not uncommon in advanced disease. Methods A retrospective series of 22 sarcoidosis patients (16 men) of mean (SD) age 46 (13) years with PH was divided into two groups depending on the absence (stage 0: n = 2, stage II: n = 4, stage III: n = 1) or presence (n = 15) of radiographic pulmonary fibrosis at the time of PH diagnosis. Results In both groups PH was moderate to severe and there was no response to acute vasodilator challenge. In non‐fibrotic cases no other cause of PH was found, suggesting a specific sarcoidosis vasculopathy, although no histological specimens were available. In cases with fibrosis there was no correlation between haemodynamics and lung volumes or arterial oxygen tensions, suggesting other mechanisms for PH in addition to pulmonary destruction and hypoxaemia. These included extrinsic arterial compression by lymphadenopathies in three cases and histologically proven pulmonary veno‐occlusive disease in the five patients who underwent lung transplantation. Ten patients received high doses of oral prednisone for PH (stage 0: n  =  1, stage II: n  =  4 and stage IV: n  =  5); three patients without pulmonary fibrosis experienced a sustained haemodynamic response. Survival of the overall population was poor (59% at 5 years). Mortality was associated with NYHA functional class IV but not with haemodynamic parameters or with lung function. Conclusion Two very different phenotypes of sarcoidosis combined with PH are observed depending on the presence or absence of pulmonary fibrosis. PH is a severe complication of sarcoidosis.

    Summary Background Sarcoidosis is an inflammatory disease that affects multiple organs. Before widespread use of computed tomography (CT), the severity of sarcoidosis was assessed based on chest X-ray abnormalities. HRCT can distinguish between active inflammatory changes and irreversible fibrosis. In this study, we analyzed different ACE levels in 148 patients diagnosed with sarcoidosis. Material/Methods We categorized these patients based on their HRCT results into four groups: 1) patients diagnosed with chronic disease; 2) patients diagnosed with non-chronic disease; 3) patients who exhibited typical HRCT changes; and 4) patients who exhibited atypical HRCT changes. Afterward the mean ACE level of each group was calculated and compared. Result The HRCT scans of chronic sarcoidosis patients tended to show more atypical sarcoidosis patterns. Moreover, there was a reverse correlation between chronicity and ACE level (P-value <0.05). Conclusions HRCT is another modality which would be useful when the diagnosis of sarcoidosis is not definite. PMID:27733890

    Sarcoidosis is a multisystem granulomatous disorder. The lungs are the principal organs affected, however, extrapulmonary involvement including disorders of the pituitary and thyroid glands has been reported but presentation with multiple endocrine manifestations is rare. We report the case of a 36-year-old African-American woman who presented with hypercalcaemia, abnormal thyroid function studies and secondary amenorrhoea. On workup including laboratory, radiological testing and biopsy she was diagnosed with sarcoidosis with multi-organ involvement. Endocrine manifestations included non-parathyroid hormone mediated hypercalcaemia related to sarcoidosis, thyroid involvement with sarcoidosis and hypothalamic-pituitary involvement with a sellar and suprasellar mass associated with secondary adrenal insufficiency, secondary hypogonadism, growth hormone deficiency and secondary hypothyroidism. We report to the best of our knowledge the first case of simultaneous multiple endocrine manifestations of sarcoidosis that included hypercalcaemia, hypopituitarism and sarcoidosis of the thyroid gland.

It is important to screen for ocular tumors both for visual prognosis and also for systemic implications. The phakomatosis comprise of multitude of benign tumors that are aysmptomatic but their detection can aid in the diagnosis of the syndrome. Retinoblastoma is the most common malignant intraocular tumor in childhood and with current treatment modalities, the survival is more than 95%. It is transmitted as an autosomal dominant fashion and hence the offsprings of all patients with the germline retinoblastoma need to be screened from birth.

    2014-12-01

    Ocular neovascularization can affect almost all the tissues of the eye: the cornea, the iris, the retina, and the choroid. Pathological neovascularization is the underlying cause of vision loss in common ocular conditions such as diabetic retinopathy, retinopathy of prematurity and age-related macular neovascularization. Glycosylation is the most common covalent posttranslational modification of proteins in mammalian cells. A growing body of evidence demonstrates that glycosylation influences the process of angiogenesis and impacts activation, proliferation, and migration of endothelial cells as well as the interaction of angiogenic endothelial cells with other cell types necessary to form blood vessels. Recent studies have provided evidence that members of the galectin class of β-galactoside-binding proteins modulate angiogenesis by novel carbohydrate-based recognition systems involving interactions between glycans of angiogenic cell surface receptors and galectins. This review discusses the significance of glycosylation and the role of galectins in the pathogenesis of ocular neovascularization. PMID:25108228

    It is a known fact that cutaneous sarcoidosis is a great imitator in dermatology. We report three cases of cutaneous sarcoidosis without systemic involvement and with varied dermatologic presentation with regard to age and morphology. Lesions mimicked various common dermatologic conditions, causing great confusion for the diagnosis and posing problems for management. Awareness of these varied morphologic presentations is essential for the early diagnosis and management of the master mimicker - cutaneous sarcoidosis. PMID:22121281

    Many ocular emergencies are difficult to diagnose in the emergency setting with conventional physical examination tools. Additionally, persistent efforts to re-examine the eye may be deleterious to a patient's overall condition. Ultrasound is an important tool because it affords physicians a rapid, portable, accurate, and dynamic tool for evaluation of a variety of ocular and orbital diseases. The importance of understanding orbital anatomy, with attention to the firm attachment points of the various layers of the eye, cannot be understated. This article describes the relevant eye anatomy, delves into the ultrasound technique, and illustrates a variety of orbital pathologies detectable by bedside ultrasound.

    An asymptomatic 40-year-old woman with a first-degree atrioventricular block presented a right atrial mass in transthoracic echocardiograms. Transesophageal echocardiograms showed abnormally thickened tissue on the interatrial septum, which extended around the aortic annulus. Multimodality examinations demonstrated lesions in the heart, lungs, liver, and spleen, suggesting sarcoidosis. She was diagnosed with cardiac sarcoidosis after we detected granulomas in a lung specimen. A right atrial mass shrunk following steroid therapy. We should therefore consider the possibility of cardiac sarcoidosis when we see wall thickening and a mass echo in the atrium. These signs may point to an early-phase lesion of cardiac sarcoidosis.

    We herein describe a case of sarcoid myositis with anti-Ku antibody positivity. Pathological findings of the muscle were compatible with sarcoidosis, but could not be completely distinguished from myositis diseases that arise from other causes. According to a physical examination, pathological findings, the detection of anti-Ku antibody and the human leukocyte antigen (HLA)-DPB1 allele, we strongly suspected that the patient developed both sarcoidosis and polymyositis. Sarcoidosis is often complicated by autoimmune diseases. This case suggests the possibility that sarcoidosis and other autoimmune diseases may have common causal genetic factors.

    The diagnosis of sarcoidosis, a multisystem granulomatous disease of unknown etiology, is established when clinicoradiological findings are supported by histological evidence of non-caseating epithelioid cell granulomas. For pathological diagnosis, an endobronchial biopsy of normal-appearing bronchial mucosa in combination with transbronchial lung biopsy (TBLB) has been reported to be useful for sarcoidosis patients in Europe or the U.S. This is the first report assessing the utility of endobronchial biopsy for diagnosis of Japanese patients with sarcoidosis. Eighteen consecutive patients with strongly suspected sarcoidosis were evaluated by endobronchial biopsy of normal-appearing bronchial mucosa, together with TBLB and bronchoalveolar lavage. The TBLB specimens demonstrated non-caseating epithelioid cell granulomas in the lungs of 11 patients (61.1%), but not any specific findings in those of other 7 patients. In contrast, endobronchial biopsy specimens confirmed a diagnosis of sarcoidosis in only one patient that required steroid therapy for deterioration of pulmonary sarcoidosis. All 18 patients of this study, including 5 patients with pathological findings obtained from extrapulmonary sites, met the pathological or clinical diagnostic criteria. In conclusion, endobronchial biopsy of normal-appearing bronchial mucosa in combination with TBLB does not improve the diagnostic capacity for detecting sarcoidosis in Japanese patients, despite earlier reports. Thus, this method is of limited usefulness as a conventional diagnostic modality for Japanese patients with suspicious sarcoidosis. The present study also suggests the racial difference in the endobronchial involvement in pulmonary sarcoidosis.

    The prevalence of sarcoidosis in the United States is unknown, with estimates ranging widely from 1 to 40 per 100,000. We sought to determine the prevalence of sarcoidosis in our health system compared to other rare lung diseases and to further establish if the prevalence was changing over time. We interrogated the electronic medical records of all patients treated in our health system from 1995 to 2010 (1.48 million patients) using the common ICD9 codes for sarcoidosis (135), lung cancer (162), and several other lung diseases characterized, like sarcoidosis, as "rare lung diseases". The patient demographic information (race, gender, age) was further analyzed to identify signature data patterns. The prevalence of sarcoidosis in our health system increased steadily from 164/100,000 in 1995 to 330/100,000 in 2010, and this trend could not be ascribed simply to changes in patient demographics or patient referral patterns. We further estimate that the prevalence of sarcoidosis exceeds 48 per 100,000 in Franklin County, Ohio, the demographic profile of which is nearly identical to that of the U.S. Sarcoidosis prevalence increased over time relative to lung cancer, a benchmark disease with stable disease prevalence, and exceeded that of other rare lung diseases. We postulate that the observed 2-fold increase in sarcoidosis disease prevalence in our health system is primarily related to improved detection and diagnostic approaches, and we conclude that the actual prevalence of sarcoidosis in central Ohio greatly exceeds current U.S. estimates.

    We report a case of fulminant sarcoidosis in a 28-year-old man presenting with skin nodules, multifocal small and large joint arthralgias, and blurred vision. Characteristic bone, soft tissue, articular, and CNS findings were evident on multimodality imaging. Bony abnormalities included near-complete destruction of a distal phalanx, "lace-like" lucent lesions, erosive arthritis, lytic lesions with and without sclerotic margins, and bone marrow replacement visible only on MRI. The extent of bony disease at time of presentation was unusual. We review the widely varying reported prevalence of imaging findings of bony sarcoidosis in the literature, and discuss reasons for this variability. We found that musculoskeletal findings at US and MRI were less specific than radiographic and CT findings, but were useful in quantifying extent of disease.

    Images were obtained with Ga-67 and bronchopulmonary lavage performed in 21 patients with sarcoidosis (31 studies). The Ga-67 index, a semiquantitative criterion, was compared to a quantitative computer index based on lung:liver activity ratios; accuracy in predicting active alveolitis (defined by lavage lymphocyte counts) was assessed and differences between 24- and 48-hour studies examined. Computer activity ratios correlated well with the Ga-67 index, which had a sensitivity of 64%, specificity of 71%, 82%, and 77%, respectively, for the computer scores. Scores at 24 and 48 hours were similar. These results suggest that (a) Ga-67 scanning is useful in staging activity in pulmonary sarcoidosis, (b) quantitative computer scores are accurate in predicting disease activity, and (c) scanning can be performed 24 or 48 hours after injection.

    A 48-year-old non-smoking man with a 6-year history of pulmonary cavitary sarcoidosis presented with acute onset of haemoptysis of approximately 600 ml. Prior episodes of haemoptysis had resolved only after serial upper lobe wedge resections bilaterally and steroids. A chest CT identified bilateral upper lobe cavitary lesions with extravasation of contrast from a large right upper lobe cavity. The patient underwent urgent bronchial angiography and subsequent bronchial artery embolisation of a left bronchial artery and three right bronchial arteries. He was started on methotrexate and steroids for refractory sarcoidosis. Two years after embolisation, the patient remained haemoptysis-free with his sarcoid well controlled on methotrexate monotherapy. PMID:23355590

    Pulmonary radioaerosol clearance rate of /sup 99m/Tc diethylenetriamine pentacetate (DTPA) in 14 patients with untreated sarcoidosis was compared with /sup 67/Ga lung scan and increased lymphocytes in the bronchoalveolar lavage (BAL) fluid. Nine healthy nonsmoking subjects had a mean DTPA clearance rate of 1.18%/min (range, 0.54 to 1.60%/min). Eight of 14 patients with sarcoidosis had clearance rates greater than 1.60%/min. Of those 8 patients with abnormal DTPA clearance, 4 had positive gallium scans, 4 had more than 17% lymphocytes in the BAL fluid, and 3 had both tests positive. To study the cause of abnormal DTPA clearance, 23 subjects (including 3 normal controls, all 14 patients with sarcoidosis, and 6 patients with localized disease on chest roentgenogram) underwent both DTPA clearance studies and BAL for quantitation of the amount of albumin in lung fluid. There was a positive correlation between the rate of DTPA clearance and the albumin concentration in lung fluid (r = 0.87, p less than 0.01).

    Gallium-67 scans have been widely employed in patients with sarcoidosis as a means of indicating alveolitis and the need for corticosteroid therapy. Observation of 32 patients followed 3 or more years after gallium scans showed no correlation between findings and later course: of 10 patients with pulmonary uptake, 7 recovered with minor residuals; of 18 patients with mediastinal of extrathoracic uptake, 10 had persistent or progressive disease; of 4 patients with negative initial scans, 2 had later progression. The value of gallium-67 scans as an aid to diagnosis was studied in 40 patients with extrapulmonary sarcoidosis. In 12 patients, abnormal lacrimal, nodal, or pulmonary uptake aided in selection of biopsy sites. Gallium-67 scans and serum ACE levels were compared in 97 patients as indices of clinical activity. Abnormal gallium-67 uptake was observed in 96.3% of the tests in active disease, and ACE level elevation occurred in 56.3%. In 24 patients with inactive or recovered disease, abnormal gallium-67 uptake occurred in 62.5% and ACE level elevation in 37.5%. Gallium-67 scans have a limited but valuable role in the diagnosis and management of sarcoidosis.

    The histopathologic diagnosis of sarcoidosis requires the presence of noncaseating granulomas. Transbronchoscopic lung biopsy (TBLB) has been considered the procedure of choice when less invasive tissue samples are unavailable. A total of 51 consecutive patients suspected of having sarcoidosis underwent combined TBLB and flexible transbronchial needle aspirate (TBNA). In 18 of the 30 patients (60 percent) with stage I disease, the diagnosis was confirmed by TBLB and 16 (53 percent) were confirmed by TBNA. The combined use of both procedures increased the diagnostic yield to 83 percent. The remaining 21 patients with stage II disease had their diagnosis confirmed in 16 (76 percent) cases by TBLB and 10 (48 percent) by TBNA with a combined diagnostic yield of 86 percent. Seven (23 percent) patients with stage I disease and 2 (10 percent) with stage II disease had their conditions diagnosed by TBNA. We conclude that combining TBNA with TBLB increases the diagnostic yield in pulmonary sarcoidosis; TBNA should complement TBLB in the diagnosis of this disease. PMID:8082345

  17. Sarcoidosis in a dental surgeon: a case report

    PubMed Central

    2010-01-01

    Introduction Although the causes of sarcoidosis are still unknown, past and current studies have provided evidence that this disease may be associated with occupational exposure to specific environmental agents. We describe a case of sarcoidosis in a dental surgeon with long exposure to inorganic dusts. To the best of our knowledge, this is the first report of this kind in the literature. Case presentation At the beginning of 2000, a 52-year-old Caucasian man, who worked as a dental surgeon, presented with shortness of breath during exercise, cough and retrosternal pain. After diagnosis of sarcoidosis, a scanning electronic microscopy with X-ray microanalysis of biopsy specimens was used in order to determine whether the disease could be traced to an occupational environmental agent. Results showed the presence of inorganic dust particles within sarcoidotic granulomas, and demonstrated that the material detected was identical to that found in a powder used by our patient for several years. Conclusions Although these results cannot be considered as definitive proof, they do however provide strong evidence that this disease may be associated with material used by dental surgeons.

    The reason why the cutaneous form of sarcoidosis is well known in the literature is because of its spectrum of manifestations granting it the fame of a Great Imitator. The mystery shrouding the pathogenesis of this rare cutaneous disease is still there (in spite of the fundamental progress of the various diagnostic methods in current day medicine). The production of the morphological substrate - the epithelioid cell granuloma - which is considered to be characteristic of skin sarcoidosis, could, however, also be the end result of a reaction to i) various specific infectious agents such as Leishmaniasis cutis, coccidioidomycosis, etc., ii) certain residual bacterial or other mycobacterial antigens which, at the moment of setting the diagnosis are - by definition - non-infectious but still immunogenic, as well as iii) different tumor antigens in lesional tissue or other location. Often, differentiating between sarcodiosis and a sarcoid-like reaction, based on the updated criteria for cutaneous sarcoidosis, is problematic to downright impossible. A future characterization of the genetic signature of the two conditions, as well as the implementation of additional mandatory panels for i) the identification of certain infectious or ii) non-infectious but immunogenic and iii) tumor antigens in the epithelioid cell granuloma (or in another location in the organism), could be a considerable contribution to the process of differentiating between the two above-mentioned conditions. This will create conditions for greater accuracy when setting the subsequent therapeutic approaches.

    In this paper we report the autopsy findings of a 57 year old woman who died unexpectedly at home. She had been complaining of shortness of breath, episodes of dry coughing, and nausea. Her past medical and social history was unremarkable. She had no previous history of any viral or bacterial disease and no history of oncological disorders. Autopsy revealed multiple grayish-white nodular lesions in the pleura and epicardial fat and areas resembling fibrosis on the cut surface of the anterior and posterior wall of the left ventricle and interventricular septum. Histological examination of the lungs and heart revealed multiple well-formed noncaseating epithelioid cell granulomas with multinucleated giant cells. Death was attributed to myocardial ischemia due to vasculitis of intramural coronary artery branches associated with sarcoidosis. Sarcoidosis is a multisystemic disease of unknown etiology characterized by the formation of noncaseating epithelioid cell granulomas in the affected organs and tissues. The diagnosis of sarcoidosis in this case was established when other causes of granulomatous disease such as tuberculosis, berylliosis, hypersensitivity pneumonitis, and giant cell myocarditis had been reasonably excluded.

    Heerfordt's syndrome is a rare manifestation of sarcoidosis characterized by the presence of facial nerve palsy, parotid gland enlargement, anterior uveitis, and low grade fever. Two cases of Heerfordt's syndrome and a literature review are presented. Case  1. A 53-year-old man presented with swelling of his right eyelid, right facial nerve palsy, and swelling of his right parotid gland. A biopsy specimen from the swollen eyelid indicated sarcoidosis and he was diagnosed with incomplete Heerfordt's syndrome based on the absence of uveitis. His symptoms were improved by corticosteroid therapy. Case  2. A 55-year-old woman presented with left facial nerve palsy, bilateral hearing loss, and swelling of her bilateral parotid glands. She had been previously diagnosed with uveitis and bilateral hilar lymphadenopathy. Although no histological confirmation was performed, she was diagnosed with complete Heerfordt's syndrome on the basis of her clinical symptoms. Swelling of the bilateral parotid glands and left facial nerve palsy were improved immediately by corticosteroid therapy. Sarcoidosis is a relatively uncommon disease for the otolaryngologist. However, the otolaryngologist may encounter Heerfordt's syndrome as this syndrome presents with facial nerve palsy and swelling of the parotid gland. Therefore, we otolaryngologists should diagnose and treat Heerfordt's syndrome appropriately in cooperation with pneumologists and ophthalmologists. PMID:26885424

    A case of chronic pulmonary sarcoidosis and hypercalciuria complicated by bilateral renal stones is reported. Urinary stones were pulverized by extracorporeal shockwave lithotripsy (ESWL) as the patient had declined any surgical procedure. The use of ESWL in conjunction with corticosteroids appears to be the treatment of choice in the management of renal stones secondary to abnormalities of calcium metabolism in sarcoidosis.

    Background Tuberculosis and sarcoidosis are chronic diseases that rarely occur concomitantly. Sarcoidosis is a multisystem granulomatous disorder characterized pathologically by the presence of non-caseating granulomas in involved tissues. Tuberculosis is infectious disease caused by Mycobacterium tuberculosis characterized by granulomas with caseous necrosis. Case presentation We present a case of 43-year-old female refugee from Kosovo with microbiological confirmation of pulmonary tuberculosis and pulmonary and skin sarcoidosis at the same time. Three weeks after corticosteroid therapy for pulmonary sarcoidosis was introduced, positive finding of mycobacterium culture of bronchial aspirate was observed. Based on these results, corticosteroid therapy was excluded and antituberculous therapy was introduced for six months. In the meantime, new nodes on face and nose appeared and skin sarcoidosis was diagnosed. The patient was given corticosteroids and colchicine according to the skin and pulmonary sarcoidosis therapy recommendation. Conclusion The authors of this study suggest that in cases when there is a dilemma in diagnosis between tuberculosis and sarcoidosis we should advance with corticosteroid therapy until we have microbiological confirmation of mycobacterium culture. This case is remarkable because this is a third described case of sarcoidosis and tuberculosis together (the first reported in Asia, the second in South Africa), and to authors knowledge, this is a first case report in Europe.

    Sarcoidosis is a multiorgan granulomatous disease of unknown origin, which frequently involves the lung and the eyes. It is rare that sarcoidosis causes cervical lymphadenopathy and a chronic continuous salivary gland swelling. In the present study, we examined how to diagnose sarcoidosis in patients complaining of a cervical mass and its clinical presentation according to 8 cases which we experienced. We undertook biopsy of the cervical lymph nodes in 7 cases, and biopsy of the parotid gland in 1 case. In cases non-caseating epithelioid cell granuloma was proved, diagnosed as sarcoidosis histopathlogically. In 6 patients, the sarcoidal lesion was in other organs, whereas in 2 patients the sarcoidal lesion was confined in the head and neck. Bilateral hilar lymphadenopathy and an elevated level of angiotensin-converting enzyme which are typical in sarcoidosis were confirmed in only one of our patients. Therefore, the diagnostic value of these tests is low for the diagnosis of sarcoidosis in the patients whose chief complaint is a cervical mass. Because 4 out of 7 cases were positive for the tuberculin test, it is imperative to distinguish between sarcoidosis and cervical tuberculous lymphadenitis by combining the culture of acid-bacilli and TB-PCR with histopathological evaluation of the biopsy specimen. We experienced one patient in whom the sarcoidal lesion developed in the skin and the eyes 20 years after the onset of cervical lymphadenopathy. It is important to follow the patients carefully, even if we diagnose the disease as sarcoidosis confined in the head and neck.

    Background In patients with sarcoidosis, sudden death is a leading cause of mortality, which may represent unrecognized cardiac involvement. Delayed-enhancement cardiovascular magnetic resonance (DE-CMR) can detect minute amounts of myocardial damage. We sought to compare DE-CMR with standard clinical evaluation for the identification of cardiac involvement. Methods and Results Eighty-one consecutive patients with biopsy proven extra-cardiac sarcoidosis were prospectively recruited for a parallel and masked comparison of cardiac involvement between: (1) DE-CMR, and (2) standard clinical evaluation using consensus criteria (modified Japanese Ministry of Health [JMH] guidelines). Standard evaluation included 12-lead electrocardiography and at least one dedicated non-CMR cardiac study (echocardiography, radionuclide scintigraphy, or cardiac catheterization). Patients were followed 21±8 months for major adverse events (death, defibrillator shock, or pacemaker requirement). Patients were predominantly middle-aged (46±11 years), female (62%), African-American (73%), had chronic sarcoidosis (median, 7 years), and preserved LVEF (median, 56%). DE-CMR identified cardiac involvement in 21 patients (26%) and JMH criteria in 10 (12%, 8 overlapping), a more than two-fold higher rate for DE-CMR (p=0.005). All patients with myocardial damage on DE-CMR had coronary disease excluded by x-ray angiography. Pathology evaluation in 15 patients (19%) identified 4 with cardiac sarcoidosis; all 4 were positive by DE-CMR whereas 2 were JMH positive. On follow-up, 8 had adverse events including 5 cardiac deaths. Patients with myocardial damage on DE-CMR had a 9-fold higher rate of adverse events and a 11.5-fold higher rate of cardiac death than patients without damage. Conclusion In patients with sarcoidosis, DE-CMR is more than twice as sensitive for cardiac involvement than current consensus criteria. Myocardial damage detected by DE-CMR appears to be associated with future adverse

    Biopharmaceuticals are making increasing impact on medicine, including treatment of indications in the eye. Macromolecular drugs are typically given by physician-administered invasive delivery methods, because non--invasive ocular delivery methods, such as eye drops, and systemic delivery, have low bioavailability and/or poor ocular targeting. There is a need to improve delivery of biopharmaceuticals to enable less-invasive delivery routes, less-frequent dosing through controlled-release drug delivery and improved drug targeting within the eye to increase efficacy and reduce side effects. This review discusses the barriers to drug delivery via various ophthalmic routes of administration in the context of macromolecule delivery and discusses efforts to develop controlled-release systems for delivery of biopharmaceuticals to the eye. The growing number of macromolecular therapies in the eye needs improved drug delivery methods that increase drug efficacy, safety and patient compliance. PMID:24998941

    Toll-like receptor 3 (TLR3) may be associated with T helper 1 immune response. This study aimed to investigate the role of a functional TLR3 single nucleotide polymorphism (SNP) in sarcoidosis. We genotyped 220 Japanese patients with sarcoidosis and 140 controls for TLR3 SNP rs3775291 to analyze its association with susceptibility to sarcoidosis and assessed its relationship to clinical features in 172 patients over 2 years. The TLR3 rs3775291 genotype was not significantly associated with disease susceptibility. However, patients with cardiac sarcoidosis (CS) significantly more frequently had the TT genotype (p < 0.01) or the T allele (p < 0.05) than those patients without CS. We conclude that TLR3 SNP rs3775291 may affect cardiac involvement in Japanese patients with sarcoidosis.

    Genetic ocular diseases are inherited Mendelian conditions (prevalence 1/1000) in which any tissue of the eye could be involved (cornea, lens, iridocomeal angle, vitrous, retina, choroid, sclera). More than 200 genes are responsible for inherited retinal dystrophies and even more genes remain to be identified. These genes belong to many metabolisms essential to the photoreceptor function. Gene therapy and retinal prosthesis are the two most promising therapeutic strategies currently in clinical trials which are expected to provide visual improvement in short term.

    Sarcoidosis is a systemic chronic granulomatous disease of unknown etiology. It predominantly involves the lungs but can affect many organs or tissues in the body, such as the lymphatic system, skin, eyes, and liver. Typical histopathological lesions are noncaseating granulomas in the affected organ or tissue. Indications, type of treatment, and duration of sarcoidosis treatment is currently debated. Despite studies showing that anti–tumor necrosis factor-α (TNF-α) treatment can successfully be used in refractory sarcoidosis, there are some case reports regarding the development of sarcoidosis with these agents. There have been reports of 47 anti-TNF-associated cases of sarcoidosis until 2012. The patient is a 54-year-old Caucasian male. During routine examinations of the patient who had been followed for psoriasis vulgaris for 20 years and who had been on several anti-TNF regimens thereafter, new pulmonary pathologies due to sarcoidosis were detected. We present here a case of sarcoidosis that developed after infliximab treatment and showed obvious radiologic regression with discontinuation of treatment. During anti-TNF treatment, it should be kept in mind that autoimmune and granulomatous diseases may develop and particular care should be given to patient follow-ups. PMID:26425632

    Background: Diagnosing cutaneous sarcoidosis and necrobiotic granulomas is challenging. Objective: Assessing the value of dermoscopy in differentiating cutaneous sarcoidosis from necrobiotic granulomas and evaluating whether their dermoscopic features will be altered after treatment. Methods: Nineteen cutaneous sarcoidosis and 11 necrobiotic granuloma patients (2 necrobiosis lipoidica, 4 granuloma annulare and 5 rheumatoid nodule) were included in this study. The diagnosis was confirmed by skin biopsy. The lesions were examined using non-contact polarized dermoscope (Dermlite 2 HR-Pro; 3Gen, San Juan Capistrano, CA). Results: Ten out of 19 cutaneous sarcoidosis patients and 7/11 necrobiotic cases group were receiving treatments (topical, intralesional or systemic steroids ± chloroquine) but still have cutaneous lesions. Treatment duration in the sarcoidosis group ranged from 2 months to 10 years (median 3 years) and in the necrobiotic cases group ranged from 3 months to 16 years (median 2 years). Pink homogenous background, translucent orange areas, white scar-like depigmentation and fine white scales were significantly associated with the cutaneous sarcoidosis compared to necrobiotic cases group. On the other hand mixed pink, white and yellowish background was significantly associated with the necrobiotic cases group. No significant difference in the dermoscopic findings was detected between treated and non-treated patients. Conclusion: Some dermoscopic findings are shared between the cutaneous sarcoidosis group and the necrobiotic cases group, yet dermoscopy could be a useful aid in differentiating them even after treatment.

    Sarcoidosis is an antigen-mediated disease of unknown aetiology, characterized by the presence of non-caseating epithelioid cell granulomas in multiple organs. Cutaneous involvement in sarcoidosis is classified as specific, when biopsy reveals non-caseating granulomas, and non-specific, typically erythema nodosum. Granulomatous skin lesions occur in 9% to 37% of patients. The skin is the second most commonly involved organ after the lung. A skin biopsy is easy to perform and enables an early diagnosis with a minor invasive procedure. Some types of specific lesions have prognostic significance and may help to predict the outcome of the systemic disease. Maculopapules, subcutaneous nodules and scar sarcoidosis are usually transient or tend to follow the course of the systemic disease. Skin plaques and lupus pernio are associated with chronic sarcoidosis. Although most cutaneous lesions of sarcoidosis do not cause significant morbidity and do not require treatment, some have cosmetic importance because they may be disfiguring and can have a strong psychosocial impact. Treatment of these lesions is a challenge since they do not respond well to conventional treatments. This manuscript reviews the clinical characteristics of the more frequent types of specific cutaneous lesions of sarcoidosis, the relationship between cutaneous involvement and systemic disease, the prognostic significance of lesions and the present state of treatment of difficult cases of cutaneous sarcoidosis.

    Sarcoidosis is an immune-mediated multisystem disease characterized by the formation of non-caseating granulomas. The pathogenesis of sarcoidosis is unclear, with proposed infectious or environmental antigens triggering an aberrant immune response in susceptible hosts. Multiple pro-inflammatory signaling pathways have been implicated in mediating macrophage activation and granuloma formation in sarcoidosis, including IFN-γ/STAT-1, IL-6/STAT-3, and NF-κB. It is difficult to distinguish sarcoidosis from other granulomatous diseases or assess disease severity and treatment response with histopathology alone. Therefore, development of improved diagnostic tools is imperative. Herein, we describe an efficient and reliable technique to classify granulomatous disease through selected gene expression and identify novel genes and cytokine pathways contributing to the pathogenesis of sarcoidosis. We quantified the expression of twenty selected mRNAs extracted from formalin-fixed paraffin embedded (FFPE) tissue (n = 38) of normal lung, suture granulomas, sarcoid granulomas, and fungal granulomas. Utilizing quantitative real-time RT-PCR we analyzed the expression of several genes, including IL-6, COX-2, MCP-1, IFN-γ, T-bet, IRF-1, Nox2, IL-33, and eotaxin-1 and revealed differential regulation between suture, sarcoidosis, and fungal granulomas. This is the first study demonstrating that quantification of target gene expression in FFPE tissue biopsies is a potentially effective diagnostic and research tool in sarcoidosis.

    Renal involvement by sarcoidosis in native and transplanted kidneys classically presents as non caseating granulomatous interstitial nephritis. However, the incidence of sarcoidosis in native and transplant kidney biopsies, its frequency as a cause of end stage renal disease and its recurrence in renal allograft are not well defined, which prompted this study. The electronic medical records and the pathology findings in native and transplant kidney biopsies reviewed at the Johns Hopkins Hospital from 1/1/2000 to 6/30/2011 were searched. A total of 51 patients with a diagnosis of sarcoidosis and renal abnormalities requiring a native kidney biopsy were identified. Granulomatous interstitial nephritis, consistent with renal sarcoidosis was identified in kidney biopsies from 19 of these subjects (37%). This is equivalent to a frequency of 0.18% of this diagnosis in a total of 10,023 biopsies from native kidney reviewed at our institution. Follow-up information was available in 10 patients with biopsy-proven renal sarcoidosis: 6 responded to treatment with prednisone, one progressed to end stage renal disease. Renal sarcoidosis was the primary cause of end stage renal disease in only 2 out of 2,331 transplants performed. Only one biopsy-proven recurrence of sarcoidosis granulomatous interstitial nephritis was identified. Conclusions Renal involvement by sarcoidosis in the form of granulomatous interstitial nephritis was a rare finding in biopsies from native kidneys reviewed at our center, and was found to be a rare cause of end stage renal disease. However, our observations indicate that recurrence of sarcoid granulomatous inflammation may occur in the transplanted kidney of patients with sarcoidosis as the original kidney disease.

    The pathogenesis of sarcoidosis, a multisystem granulomatous disorder, is mediated through immunoregulatory pathways. While sarcoidosis clusters in families, inherited risk factors remain undefined. In search of possible sarcoidosis susceptibility genes, we examined anonymous polymorphic genetic markers tightly linked to six different candidate gene regions on chromosomes 2q13, 5q31, 6p23-25, 7p14-15, 14q11 and 22q11. These candidate regions contain T cell receptor, interleukin (IL) and interferon regulatory factor (IRF) genes. Our study population consisted of 105 African-American sarcoidosis cases and 95 unrelated healthy controls. The allelic frequency distribution of two out of the six markers, IL-1 alpha marker (p = 0.010) on 2q13 and the F13A marker (p = 0.0006) on 6p23-25, was statistically significantly different in cases compared with controls. The two alleles most strongly associated with sarcoidosis were IL-1 alpha*137 (Odds Ratio (OR) = 2.60; 95% confidence interval (CI) = 1.36-4.98) and F13A*188 (OR = 2.42; 95% CI = 1.37-4.30). Individuals that had both of these alleles were at a six-fold increased risk for sarcoidosis (OR = 6.19; 95% CI = 2.54-15.10). Restricting the analysis to cases with at least one first or second-degree relative affected with sarcoidosis increased the OR to 15.38. IL-1 levels are elevated in sarcoidosis and the F13A marker is tightly linked to a gene that codes for a newly identified interferon regulatory factor protein (IRF-4), which is thought to play a role in T cell effector functions. Our results suggest genetic susceptibility to sarcoidosis may be conferred by more than one immune-related gene that act synergistically on disease risk.

  19. Ocular tuberculosis: current perspectives

    The World Health Organization currently estimates that nearly two billion people, or one-third of the world’s population, are infected by tuberculosis, and that roughly 10% of the infected people are symptomatic. Tuberculosis affects the lungs in 80% of patients, while in the remaining 20% the disease may affect other organs, including the eye. Uveitis can be seen concurrently with tuberculosis, but a direct association is difficult to prove. Ocular tuberculosis is usually not associated with clinical evidence of pulmonary tuberculosis, as up to 60% of extrapulmonary tuberculosis patients may not have pulmonary disease. The diagnosis of tuberculous uveitis is often problematic and in nearly all reported cases, the diagnosis was only presumptive. Tuberculous uveitis is a great mimicker of various uveitis entities and it can be considered in the differential diagnosis of any type of intraocular inflammation. It is still unknown if ocular manifestations result from a direct mycobacterium infection or hypersensitivity reaction and this is reflected on the management of tuberculous uveitis. Prevalence of tuberculosis as an etiology of uveitis may reach up to 10% in endemic areas. Tuberculous uveitis is a vision-threatening disease that inevitably leads to blindness if not properly diagnosed and treated. The aim of this review is to illustrate the various clinical features and management of presumed tuberculous uveitis. The current review focuses on the diagnostic criteria, significance of tuberculin skin test, and use of systemic corticosteroids in the management of tuberculous uveitis as recommended in recent publications.

    Objectives: To describe the clinical characteristics of ocular injuries sustained in hurling in the south of Ireland and to investigate reasons for non-use of protective headgear and eye wear. Results: Hurling related eye injuries occurred most commonly in young men. Fifty two patients (17%) required hospital admission, with hyphaema accounting for 71% of admissions. Ten injuries required intraocular surgical intervention: retinal detachment repair (5); macular hole surgery (1); repair of partial thickness corneal laceration (1); repair of globe perforation (1); enucleation (1); trabeculectomy for post-traumatic glaucoma (1). Fourteen eyes (4.5%) had a final best corrected visual acuity (BCVA) of <6/12 and six (2%) had BCVA <3/60. In the survey, 63 players (48.5%) reported wearing no protective facemask while playing hurling. Impairment of vision was the most common reason cited for non-use. Conclusions: Hurling related injury is a significant, and preventable, cause of ocular morbidity in young men in Ireland. The routine use of appropriate protective headgear and faceguards would result in a dramatic reduction in the incidence and severity of these injuries, and should be mandatory. PMID:16046328

    Ocular drug delivery has been a major challenge to pharmacologists and drug delivery scientists due to its unique anatomy and physiology. Static barriers (different layers of cornea, sclera, and retina including blood aqueous and blood-retinal barriers), dynamic barriers (choroidal and conjunctival blood flow, lymphatic clearance, and tear dilution), and efflux pumps in conjunction pose a significant challenge for delivery of a drug alone or in a dosage form, especially to the posterior segment. Identification of influx transporters on various ocular tissues and designing a transporter-targeted delivery of a parent drug has gathered momentum in recent years. Parallelly, colloidal dosage forms such as nanoparticles, nanomicelles, liposomes, and microemulsions have been widely explored to overcome various static and dynamic barriers. Novel drug delivery strategies such as bioadhesive gels and fibrin sealant-based approaches were developed to sustain drug levels at the target site. Designing noninvasive sustained drug delivery systems and exploring the feasibility of topical application to deliver drugs to the posterior segment may drastically improve drug delivery in the years to come. Current developments in the field of ophthalmic drug delivery promise a significant improvement in overcoming the challenges posed by various anterior and posterior segment diseases. PMID:20437123

    Autoimmune haemolytic anaemia is not a well-recognised complication of sarcoidosis. We describe the case of a 30-year-old female who presented with acute warm haemolytic anaemia and widespread lymphadenopathy. Sarcoidosis was diagnosed on lymph node biopsy and further investigation. The haemolytic anaemia responded only to a high dose of steroids. Evidence regarding treatment of steroid refractory autoimmune haemolysis secondary to sarcoidosis is lacking. Based on the emergent evidence that both disorders share common immunopathogenic mechanisms involving Th1 and Th17 lymphocytes, our patient was given rituximab and mycophenolate mofetil to successfully suppress the haemolysis and sarcoid activity.

    Sarcoidosis is a multisystem granulomatous disease of unknown aetiology characterized by increased inflammation, and results from gene-environment interactions. Proteinase-activated receptor-1 mediates the interplay between coagulation and inflammation. The rs2227744G > A promoter single nucleotide polymorphism has been linked to inflammation, cardiovascular disease and chronic obstructive pulmonary disease exacerbations. Using a case-control study (184 cases with sarcoidosis and 368 controls), we show that the rs2227744A allele significantly associates with protection from sarcoidosis (P = 0.003, OR = 0.68 (0.52-0.88)).

    Renal sarcoidosis embraces a wide variety of clinical patterns. Renal vascular involvement has seldom been reported and usually in the setting of systemic vasculitis. We report the case of a 22-year-old patient in whom inaugural manifestation of renal sarcoidosis consisted of severe hypertension associated with bilateral perfusion defects and tumour-like nodules. In the setting of renal sarcoidosis, our case suggests that renin-dependant hypertension may arise from renal ischaemia as a result of extrinsic compression of kidney blood vessels due to severe granulomatous inflammation.

Follow-up FDG PET/CT with a 3-day pretest diet modification showed suppression of overall myocardial uptake of FDG but with multifocal abnormal FDG uptake in the myocardium regions corresponding to the previous MRI findings. Additional noncardiac active sarcoidosis involving multiple organ and lymph nodes were also visualized on FDG PET/CT. PMID:26544904

    Sarcoidosis is a granulomatous disease of unknown etiology, which may affect multiple organ systems. The skin is involved in up to one-third of cases. The development of granulomatous lesions within tattoos is a well-recognized phenomenon in patients with sarcoidosis. The characteristic histology shows non-caseating granulomas; however similar findings may be seen in foreign body granulomas. We report on a patient, who developed sarcoidal granulomas within the black pigment of his tattoos. This subsequently led to the diagnosis of pulmonary sarcoidosis.

    Sarcoidosis is an autoimmune disease of unknown etiology characterized by the presence of non-caseating epithelioid cell granulomas in multiple organs. Cutaneous sarcoidosis occurs in approximately 25% of the cases. Sarcoid reactions on old scars, traumatized skin sites and around embedded foreign material have long been observed. For the past 70 years, sarcoidal granulomas on tattoos and permanent make-up have also been documented. Granulomatous and sarcoidal tattoo reactions may be the first and sometimes only cutaneous manifestation of systemic sarcoidosis. This review summarizes the currently available data on this topic and discusses the issues related to the diagnosis, management and physiopathogeny of sarcoidal reactions on tattoos.

    A report is given of a rare case of vertebral sarcoidosis with negative conventional spinal x-ray films, yet with typical cystic lesions of the spine found incidentally during abdominal computerized axial tomography (CAT). The patient was a 28-year-old black man, who was admitted for evaluation of a 1 1/2-year history of diffuse myalgias, intermittent fever to 102 F orally, bilateral hilar adenopathy, and leukopenia. A technetium polyphosphate bone scan revealed diffuse areas of increased uptake over the sternum, entire vertebral column, and pelvis. Conventional x-ray films of the cervical, thoracic, and lumbar spine, and an AP view of the pelvis were all normal. Chest x-ray film revealed only bilateral hilar adenopathy. During the course of an extensive negative evaluation for infection, an abdominal CAT scan was done, showing multiple, small, sclerotic-rimmed cysts at multiple levels of the lower thoracic and lumbar spine. Bone marrow biopsy revealed only changes consistent with anemia of chronic disease. Mediastinal lymph node biopsy revealed noncaseating granulomas. A tentative diagnosis of sarcoidosis was made, and treatment with prednisone, isoniazid and rifampin was begun. Within two weeks of initiation of prednisone therapy, the patient was symptom-free. A repeat technetium polyphosphate bone scan revealed only a small residual area of mildly increased uptake over the upper thoracic vertebrae.

    Classic studies of tuberculosis (TB) revealed morphologic evidence of considerable heterogeneity of macrophages (MØs), but the functional significance of this heterogeneity remains unknown. We have used newly available specific antibodies for selected membrane and secretory molecules to examine the phenotype of MØs in situ in a range of South African patients with TB, compared with sarcoidosis. Patients were human immunodeficiency virus-negative adults and children, and the examined biopsy specimens included lung and lymph nodes. Mature pulmonary MØs (alveolar, interstitial, epithelioid and multinucleated giant cells) selectively expressed scavenger receptor type A and a novel carboxypeptidase-like antigen called carboxypeptidase-related vitellogenin-like MØ molecule (CPVL). CPVL did not display enhanced expression in sarcoidosis, vs. TB patients, as observed with angiotensin-converting enzyme (ACE), a related molecule. Immunocytochemical studies with surfactant proteins (SP)-A and -D showed that type II alveolar cells expressed these collectins, as did MØs, possibly after binding of secreted proteins. Studies with an antibody specific for the C-terminus of fractalkine, a tethered CX3C chemokine, confirmed synthesis of this molecule by bronchiolar epithelial cells and occasional endothelial cells. These studies provide new marker antigens and extend previous studies on MØ differentiation, activation and local interactions in chronic human granulomatous inflammation in the lung. PMID:14748748

    Multiplex protein technology has the potential to identify biomarkers for the differentiation, classification and improved understanding of the pathogenesis of interstitial lung disease. The aim of this study was to determine whether a 30-inflammatory biomarker panel could discriminate between healthy controls, sarcoidosis and systemic sclerosis (SSc) patients independently of other clinical indicators. We also evaluated whether a panel of biomarkers could differentiate between the presence or absence of lung fibrosis in SSc patients. We measured 30 circulating biomarkers in 20 SSc patients, 21 sarcoidosis patients and 20 healthy controls using Luminex bead technology and used Fisher's discriminant function analysis to establish the groups of classification mediators. There were significant differences in median concentration measurements between study groups for 20 of the mediators but with considerable range overlap between the groups, limiting group differentiation by single analyte measurements. However, a 17-analyte biomarker model correctly classified 90% of study individuals to their respective group and another 14-biomarker panel correctly identified the presence of lung fibrosis in SSc patients. These findings, if they are corroborated by independent studies in other centres, have potential for clinical application and may generate novel insights into the modulation of immune profiles during disease evolution.

    Diabetes mellitus (DM) is a important health problem that induces ernestful complications and it causes significant morbidity owing to specific microvascular complications such as, retinopathy, nephropathy and neuropathy, and macrovascular complications such as, ischaemic heart disease, and peripheral vasculopathy. It can affect children, young people and adults and is becoming more common. Ocular complications associated with DM are progressive and rapidly becoming the world’s most significant cause of morbidity and are preventable with early detection and timely treatment. This review provides an overview of five main ocular complications associated with DM, diabetic retinopathy and papillopathy, cataract, glaucoma, and ocular surface diseases. PMID:25685281

    Ocular neuromyotonia is a paroxysmal monocular deviation that results from spasm of eye muscles secondary to spontaneous discharges from third, fourth, or sixth nerve axons. We observed this rare disorder in four patients who had been treated with radiation for tumors in the region of the sella turcica and cavernous sinus. Based on these cases and four others identified in the literature it would appear that radiation predisposes to a cranial neuropathy in which ocular neuromyotonia may be the major manifestation. Radiation appears to be the most common cause of ocular neuromyotonia.

  16. Ocular Screening System

    1987-01-01

    Used to detect eye problems in children through analysis of retinal reflexes, the system incorporates image processing techniques. VISISCREEN's photorefractor is basically a 35 millimeter camera with a telephoto lens and an electronic flash. By making a color photograph, the system can test the human eye for refractive error and obstruction in the cornea or lens. Ocular alignment problems are detected by imaging both eyes simultaneously. Electronic flash sends light into the eyes and the light is reflected from the retina back to the camera lens. Photorefractor analyzes the retinal reflexes generated by the subject's response to the flash and produces an image of the subject's eyes in which the pupils are variously colored. The nature of a defect, where such exists, is identifiable by atrained observer's visual examination.

A 2-year-old girl was brought to our outpatient clinic with a complaint of irritable crying after being taken to a stream in Hualien 1 day previous, where she played in the water. The parents noticed that she rubbed her right eye a lot. Upon examination, the girl had good fix and follow in either eye. Slit-lamp examination showed conjunctival injection with a moving dark black–brown foreign body partly attached in the lower conjunctiva. After applying topical anesthetics, the leech, measuring 1 cm in length, was extracted under a microscope. The patient began using topical antibiotic and corticosteroid agents. By 1 week after extraction, the patient had no obvious symptoms or signs, except for a limited subconjunctival hemorrhage, and no corneal/scleral involvement was observed. PMID:25784786

Eye reflex is recorded on color film when the eyes are exposed to a flash of light. The photographs are compared with predetermined standards to detect eye defects. The base structure of the ocular screening system is a folding interconnect structure, comprising hinged sections. Attached to one end of the structure is a head positioning station which comprises vertical support, a head positioning bracket having one end attached to the top of the support, and two head positioning lamps to verify precise head positioning. At the opposite end of the interconnect structure is a camera station with camera, electronic flash unit, and blinking fixation lamp, for photographing the eyes of persons being evaluated.

    Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive procedure with a low rate of complications. It is used in the diagnosis of malignant and benign disease such as sarcoidosis. We report a case a 42-year-old man who had undergone EBUS-TBNA for diagnosis of mediastinal and hilar lymph node enlargement. Sarcoidosis was diagnosed on cytologic examination. Three weeks after the procedure, he developed a mediastinal abscess secondary to EBUS-TBNA. Sarcoidosis may be a risk factor for mediastinal infection complication. A local immune defect related to sarcoidosis may explain this risk. Our case underlines the importance of considering and recognizing this complication, and its possibility should be taken into account when undertaking the procedure for benign disease.

    Sarcoidosis is a multi-system inflammatory disorder of unknown etiology that is manifested by the presence of non-caseating granulomas. Multiple pulmonary nodules are rare presentations of sarcoidosis. We report a case of nodular sarcoidosis in a young male of Middle-East origin who had initially presented with bilateral painful ankle edema. His chest X-ray showed multiple bilateral pulmonary nodules. A high resolution computed tomography scan of the chest demonstrated multiple pulmonary nodular lesions and also mediastinal and hilar lymphadenopathy. Subsequent biopsies revealed non-necrotizing granuloma with multi-nucleated giant cells indicative of sarcoidosis. An appropriate work-up was done to confirm the true nature of the nodules and facilitate treatment. PMID:27757192

    In a series of 34 patients with sarcoidosis affecting the upper respiratory tract and nose, 26 had lupus pernio (LP) and 17 had sarcoidosis of the upper respiratory tract (SURT). In nine patients these features coexisted. A patient presenting with SURT carried a 50% risk of developing LP although one feature could be present without the other. Both were disorders of women of the child-bearing years of life. SURT, like LP, was an indicator of chronic fibrotic sarcoidosis, developing insidiously and progressing indolently over the years. It was complicated by ulceration, septal perforation, and LP. Three patients had nasal septal perforations, in two instances following submucous resection. This operation is contraindicated in patients with active sarcoidosis, particularly when granulomas are found on nasal biopsy. The Kveim-Siltzbach skin test was positive in all patients with SURT, making it invaluable in the differential diagnosis of granuloma of the nasal cavity. PMID:1013937

    Sarcoidosis is a common multi-system disease characterized histolopathologically by the formation of non-caseating granulomas in the affected tissues. The oral involvement of sarcoidosis is relatively rare with less than 70 reported cases in literature while an oral lesion as the initial presenting sign is even less common. Oral lesions of sarcoidosis may mimic the lesions of other serious systemic diseases including Crohn's disease and tuberculosis as well as lesions localized to the orofacial region such as orofacial granulomatosis. This report presents a case of non-progressive sarcoidosis where the initial presenting symptom was a lesion in the buccal vestibule attached to the gingivae. A brief review of the pathology and clinical features is also presented.

    Sarcoidosis can cause fatal diffuse lung fibrosis in the end stage, so its early diagnosis and treatment can prevent the progression of fibrosis. Predominant ground glass opacity on high-resolution CT (HRCT) scans is a rare presentation of sarcoidosis. We report the case of a patient who presented with very few symptoms and signs of sarcoidosis; HRCT revealed large-scale ground glass opacity and minor lymphadenopathy. Bronchoalveolar lavage fluid contained turbid liquid. Sarcoidosis could be confirmed only based on pathological examination of the resected tissue. The patient was administrated prednisone at 40 mg/d orally with tapering of the dose. Lung HRCT scans taken 6 months after the prednisone treatment showed ablation of the ground glass opacity. This case report sheds light on an atypical HRCT presentation of sarcoidosis; the findings here will be useful for the early diagnosis of sarcoidosis and prevention of fatal complications.

    Ga-67 and Tl-201 SPECT was performed to evaluate cardiac sarcoidosis in a 15-year-old boy. Tl-201 SPECT imaging showed decreased uptake in the inferior to lateral wall and Ga-67 accumulation in the area of decreased Tl-201 uptake. These findings suggested cardiac sarcoidosis, and cardiac biopsy confirmed this diagnosis. After corticosteroid therapy, myocardial uptake of Ga-67 disappeared and myocardial TI-201 uptake became more homogeneous.

    Two patients with myocardial sarcoidosis are presented, both of whom underwent SPECT imaging with Tl-201 and Ga-67. The first had Ga-67 myocardial uptake with a Tl-201 defect, which disappeared with corticosteroid therapy. The second had multiple Tl-201 defects without Ga-67 uptake, which persisted despite corticosteroid therapy. Therefore, the combination of Tl-201 and Ga-67 imaging may be useful for recognizing myocardial sarcoidosis and for predicting the response to corticosteroid therapy.

The patient was treated successfully with systemic corticosteroids and azathioprine. She later developed cutaneous, lymphatic, and pulmonary granulomatous disease. Isolated biliary disease is a rare initial presentation of systemic sarcoidosis. PMID:27761479

    Sarcoidosis is a multisystem inflammatory disorder of unknown cause which can affect any organ system. Autosomal dominant lysozyme amyloidosis is a very rare form of hereditary amyloidosis. The Arg64 variant is extraordinarily rare with each family showing a particular pattern of organ involvement, however while Sicca syndrome, gastrointestinal involvement and renal failure are common, lymph node involvement is very rare. In this case report we describe the first reported case of sarcoidosis in association with hereditary lysozyme amyloidosis. PMID:24351625

    The aim of our work is to promote the awareness about the development of sarcoidosis after antineoplastic therapy in order to avoid diagnostic errors with FDG-PET/CT findings. We report the observation of three women with breast, cervix and stomach treated cancers who developed a sarcoidosis after the end of anti-neoplastic therapy. The utility of FDG-PET/CT is in pinpointing the organs candidates for diagnostic biopsy and not distinguishing between the malignancy and granulomatous or inflammatory diseases.

    Sarcoidosis is an inflammatory disease with multisystem involvement characterized by the presence of noncaseating granulomas. It can affect virtually every organ of the body, with lung involvement being most common occurring in >90% of patients. Other organs affected are skin, eye and liver. Skin involvement is common, affecting 25-35%. Here we present a rare case of a 15 year-old male with isolated oculocutaneous sarcoidosis without systemic involvement.

    Sarcoidosis is a multisystemic disease of unknown origin characterized by the formation of non-caseating granulomas. Thoracic involvement is the most common presentation; however, sarcoidosis can involve almost any other organ. To the best of our knowledge there have been only 10 cases of splenic sarcoidosis reported in the English literature, with no reports of sarcoidosis of an accessory spleen. The present study reports a case of isolated sarcoidosis of an accessory spleen in the greater omentum, which was identified postoperatively in a 44-year-old female. Chest X-ray results were normal. Gastric endoscopy demonstrated an ulcer in the antrum, which was confirmed to be a signet-ring cell carcinoma via biopsy. Computed tomography of the abdomen revealed mild thickening of the posterior antrum, and a mass in the inferior pole of the left kidney. Intraoperatively, no masses were detected in the liver and spleen. Moreover, no enlarged lymph nodes were detected in the abdominal cavity, pelvic cavity, mesenteric and para-aorta. Following a radical distal gastrectomy and left radical nephrectomy, postoperative pathology demonstrated signet-ring cell carcinoma in the antrum, left renal clear cell cancer and a red lesion measuring 0.5×0.5 cm in the greater omentum, which was similar to the spleen in the splenic cavity and was regarded as an accessory spleen. Following exclusion of fungi and acid-fast bacilli as causative agents, sarcoidosis of the accessory spleen in the greater omentum was confirmed. The patient recovered uneventfully and was discharged on day 8 postoperation. The patient remained alive after two-year follow-up without sarcoidosis and malignant tumor recurrence. The present case demonstrated that, intraoperatively, comprehensive exploration should be conducted to exclude the accessory spleen, which may also suffer from sarcoidosis. PMID:27284324

    To study the occurrence and incidence of different ocular manifestations in rheumatoid arthritis a random cross-sectional study was carried out among 54 patients with active rheumatoid arthritis. The patients were examined thoroughly to detect any ocular disease associated with rheumatoid arthritis. Complete ocular examination with special emphasis on anterior segment evaluation and tearfilm study was done. Two-thirds of the patients examined had some kind of visual problem at presentation. Three patients (5.55%) had marked dry eye with another 20 (37.03%) having borderline tear deficiency. Two cases ( 3.70% ) of episcleritis were also seen. No cases of scleritis or retinopathy were found. The most common ocular association with rheumatoid arthritis was secondary Sjogren's syndrome. Other conditions include episcleritis and marginal keratitis.

    2013-01-01

    SUMMARY Respiratory viruses (including adenovirus, influenza virus, respiratory syncytial virus, coronavirus, and rhinovirus) cause a broad spectrum of disease in humans, ranging from mild influenza-like symptoms to acute respiratory failure. While species D adenoviruses and subtype H7 influenza viruses are known to possess an ocular tropism, documented human ocular disease has been reported following infection with all principal respiratory viruses. In this review, we describe the anatomical proximity and cellular receptor distribution between ocular and respiratory tissues. All major respiratory viruses and their association with human ocular disease are discussed. Research utilizing in vitro and in vivo models to study the ability of respiratory viruses to use the eye as a portal of entry as well as a primary site of virus replication is highlighted. Identification of shared receptor-binding preferences, host responses, and laboratory modeling protocols among these viruses provides a needed bridge between clinical and laboratory studies of virus tropism.

    Previous reports identified an association between sarcoidosis and an insertion/deletion (I/D) polymorphism in angiotensin-converting enzyme. Our meta-analysis of articles published between March 1996 and June 2013 identified studies in the PubMed, EMBASE, and the China National Knowledge Infrastructure databases. We examined whether angiotensin-converting enzyme polymorphisms influence sarcoidosis susceptibility. The strength of the association between I/D polymorphisms and sarcoidosis risk was measured based on the odds ratio and 95% confidence interval. Analysis was based on recessive and dominant models. Ethnic subgroup analysis from 18 articles (1882 cases and 3066 controls) showed that DD homozygote carriers were at a slightly increased risk of sarcoidosis compared with II homozygotes and DI heterozygotes (P = 0.03). Comparison of DD plus DI vs II revealed no significant association with sarcoidosis in group and ethnic subgroup analysis. We found that the I/D polymorphism in the angiotensin-converting enzyme gene was not associated with a major risk of sarcoidosis. PMID:25966127

    Sarcoidosis is a multi-system inflammatory disease with organ involvement that varies by race and sex. Family studies indicate that genes play a role in the etiology and extent of organ involvement in sarcoidosis. In this study, we evaluated whether 25 variants distributed in 19 genes with a known role in inflammation were associated with erythema nodosum status in 659 sarcoidosis patients and 658 controls from A Case–Control Etiologic Study of Sarcoidosis (ACCESS). We found no association with affectation status; however, a variant in the promoter of tumor necrosis factor (TNF) at position −308 was found to be associated with erythema nodosum in Caucasian sarcoidosis patients (study-wide P = 0.027). When separated by sex, a variant in intron 1 of lymphotoxin-α (LTA), a gene adjacent to TNF, was associated with erythema nodosum in female Caucasian sarcoidosis patients (study-wide P = 0.027). These DNA variants frequently occur together in Caucasians, and each variant has individually been associated with erythema nodosum in sarcoidosis patients. These results confirm that variation in the LTA/TNF gene cluster modifies a major skin manifestation of sarcoidosis and may explain the higher rate of erythema nodosum in females with sarcoidosis.

    Histologic and electron microscopic study of the epidermis in, respectively, 30 and 4 patients with skin sarcoidosis has revealed that atrophy of the epidermis is the most incident condition, whose severity depends on microcirculation disorders that are explained by the location of the epithelioid-cell granulomas relative to skin microcirculatory bed. Moderate atrophy involves the following ultrastructural changes in the keratinocytes: increased count of ribosomes and mitochondria, tonofibril condensation, perinuclear vacuolization, separation of individual cellular contact sites. If atrophy is well manifest, basal keratinocytes grow in size and the nuclei in them are positioned apically. These data suggest that drugs improving the microcirculation be prescribed to such patients in order to obliterate possible cosmetic defects.

    A 60 year old male with a medical history of pulmonary sarcoidosis and chronic low testosterone presented to his allergist for excessive lacrimation. Computed tomography (CT) scan of sinuses ordered for possible blocked nasolacrimal duct revealed an abnormal expansion of the sella turcica. Magnetic resonance imaging suggested a homogeneously enhancing 4 cm soft tissue mass enveloping the internal carotid and abutting the optic nerves. Since the patient indicated no symptoms, it was felt to be consistent with a pituitary incidentaloma. Laboratory investigation showed only minimally elevated prolactin. Visual field testing at the office was normal but computed campimetry was suggestive of few minimally depressed points in the supra-temporal quadrant on the right. Even with high suspicion of neurosarcoidosis, the patient had a surgical indication so he underwent transsphenoidal excision of the mass with no complications. Pathology was consistent with a null-cell pituitary adenoma. PMID:25147632

    Exposure to Beryllium (Be) can cause sensitization (BeS) and chronic beryllium disease (CBD) in some individuals.  Even relatively low exposures may be sufficient to generate an asymptomatic, or in some cases a symptomatic, immune response. Since the clinical presentation of CBD is similar to that of sarcoidosis, it is helpful to have information on exposure to beryllium in order to reduce misdiagnosis. The purpose of this pilot study is to explore the occurrence of Be surface deposits at worksites with little or no previous reported use of commercially available Be products.  The workplaces chosen for this study represent a convenience sample of businesses in eastern Iowa. One hundred thirty-six surface dust samples were collected from 27 businesses for analysis of Be. The results were then divided into categories by the amount of detected Be according to U.S. Department of Energy guidelines as described in 10 CFR 850.30 and 10 CFR 850.31. Overall, at least one of the samples at 78% of the work sites tested contained deposited Be above the analytical limit of quantitation (0.035 µg beryllium per sample).  Beryllium was detected in 46% of the samples collected. Twelve percent of the samples exceeded 0.2 µg/100 cm² and 4% of the samples exceeded a Be concentration of 3 µg/100 cm². The findings from this study suggest that there may be a wider range and greater number of work environments that have the potential for Be exposure than has been documented previously.  These findings could have implications for the accurate diagnosis of sarcoidosis.

    Ocular pathology in the first European case of human bat-borne rabies is described. The patient was a 30-year-old bat scientist who seven weeks after bat bite developed neurological symptoms and died 23 days later. Rabies virus antigens were detected in brain smears. After extensive virological studies the virus turned out to be a rabies-related virus, closely resembling the Duvenhage virus isolated from bats in South Africa in 1980. By light microscopy focal chronic inflammatory infiltration of the ciliary body and of the choroid was found. PAS-positive exudate was seen in the subretinal and in the outer plexiform layers of the retina, and retinal veins showed endothelial damage and perivascular inflammation. Many of the retinal ganglion cells were destroyed. The presence of rabies-related viral antigen in the retinal ganglion cells was shown by positive cytoplasmic immunofluorescence, though electron microscopy failed to identify definite viral structures in the retina. By immunohistochemistry glial fibrillary acidic protein was observed in the Müller's cells, which are normally negative for this antigen but express it as a reactive change when the retina is damaged. Synaptophysin, a constituent of presynaptic vesicles of normal retinal neurons, was not detected in the retina. Images PMID:2920157

    The BTNL2 gene is a member of the B7 receptor family that probably functions as a T-cell costimulatory molecule. It resides in the class II major histocompatibility complex (MHC) region of chromosome 6p and has recently been associated with sarcoidosis susceptibility in a white German population. We sought to replicate the BTNL2 association in an African American family-based study population (n=219 nuclear families) and two case-control populations—one African American (n=295 pairs) and one white (n=366 pairs). Ten SNPs were detected within a 490-bp region spanning exon/intron 5 of BTNL2. Haplotype variation within this region was significantly associated with sarcoidosis in all three study populations but more so in whites (P=.0006) than in the African American case-control (P=.02) or family-based (P=.03) samples. The previously reported BTNL2 SNP with the strongest sarcoidosis association, rs2076530, was also the SNP with the strongest association in our white population (P<.0001). The A allele of rs2076530 results in a premature exon-splice site and increases risk for sarcoidosis (odds ratio=2.03; 95% confidence interval 1.32–3.12). Although rs2076530 was not associated with sarcoidosis in either African American sample, a three-locus haplotype that included rs2076530 was associated with sarcoidosis across all three study samples. Multivariable logistic regression analyses showed that BTNL2 effects are independent of human leukocyte antigen class II genes in whites but may interact antagonistically in African Americans. Our results underscore the complexity of genetic risk for sarcoidosis emanating from the MHC region. PMID:16080124

  7. [Hypercalcemia in sarcoidosis--case report, prevalence, pathophysiology and therapeutic options].

    PubMed

    2007-05-01

    Hypercalcemia is a highly prevalent complication of sarcoidosis. A medical history of a patient with sarcoidosis is shown as case report. Depending on the population studied about 2-63% of sarcoidosis patients show hypercalcemia. The major difference in the prevalence of hypercalcemia may be in part due to the undulating course of subacute sarcoidosis, so hypercalcemia may be missed when serum calcium is not frequently measured. Hypercalciuria appears to be twice as prevalent then hypercalcemia and should be looked for in every sarcoidosis patient. Hypercalcemia in sarcoidosis is due to the uncontrolled synthesis of 1,25-dihydroxyvitamin D3 by macrophages. 1,25-dihydroxyvitamin D3 leads to an increased absorption of calcium in the intestine and to an increased resorption of calcium in the bone. Immunoregulatory properties have been ascribed to 1,25-dihydroxyvitamin D3. It is an important inhibitor of interleukin-2 and of interferon-gamma-synthesis, two cytokines that are important in granuloma formation in sarcoidosis. It is thought that 1,25-dihydroxyvitamin D3 counterregulates uncontrolled granuloma formation. Treatment of hypercalcemia depends on the serum level of hypercalcemia and its persistence. Generally sarcoidotic patients should be advised to avoid sun exposition to reduce vitamin D3 synthesis in the skin, to omit fish oils that are rich of vitamin D and to produce more than two liters urine a day by adapting fluid intake. Although severe hypercalcemia seems to be rare, glucocorticosteroid treatment should be started if corrected total calcium level rises beyond 3 mmol/l. If hypercalcemia is symptomatic, treatment should be started even at lower levels. Glucocorticosteroids act by inhibition of the overly 1alpha-hydroxylase activity of macrophages. Alternatively, treatment with chloroquine or ketoconazole can be established. If isolated hypercalciuria without hypercalcemia is present with evidence for recurrent nephrolithiasis, patients can be treated

    Introduction Sarcoidosis is an incurable, chronic granulomatous disease primarily involving the lungs and lymph nodes of unknown aetiology, treated with non-specific anti-inflammatory/immunosuppressive drugs. Persistently symptomatic patients worsen with a disabling, potentially fatal clinical course. To determine a possible infectious cause, we correlated in a case-control study the clinical information with the presence of bacterial DNA in sarcoidosis mediastinal lymph nodes compared with control lymph nodes resected during cancer surgery. Methods We retrospectively studied formalin-fixed, paraffin-embedded, mediastinal lymph nodes from 30 patients with sarcoidosis and 30 control patients with lung cancer. Nucleic acids were extracted from nodes, evaluated by ribosomal RNA PCR for bacterial 16S ribosomal DNA and the results were sequenced and compared with a bacterial sequence library. Clinical information was correlated. Results 11/30 (36.7%) of lymph nodes from patients with sarcoidosis had detectable bacterial DNA, significantly more than control patient lymph nodes (2/30, 6.7%), p=0.00516. At presentation, 19/30 (63.3%) patients with sarcoidosis were symptomatic including all patients with detectable bacterial DNA. Radiographically, there were 18 stage I and 12 stage II patients. All stage II patients were symptomatic and 75% had PCR-detectable bacteria. After a mean follow-up of 52.8±32.8 months, all patients with PCR-detectable bacteria in this series were persistently symptomatic requiring treatment. Discussion 36.6% of patients with sarcoidosis had detectable bacterial DNA on presentation, all of these patients were quite symptomatic and most were radiographically advanced stage II. These findings suggest that bacterial DNA-positive, symptomatic patients have more aggressive sarcoidosis that persists long term and might benefit from antimicrobial treatment directed against this presumed chronic granulomatous infection.

    Background Assessment of the clinical course of sarcoidosis requires long-term observation. However, the appropriate period of follow-up for sarcoidosis remains unclear, especially in patients without indication of corticosteroid therapy at the time of diagnosis. Objective This study aimed to clarify the cumulative incidence and identify risk factors for disease progression in corticosteroid-naïve sarcoidosis patients. Methods The clinical courses of 150 Japanese patients with sarcoidosis, who were followed for more than 2 years and had no indication for corticosteroid therapy at diagnosis, were retrospectively reviewed. Disease progression was defined as worsening of pulmonary sarcoidosis, development of new organ involvement, or extrapulmonary organ damage. The cumulative incidence of progression was estimated by generating a cumulative incidence curve with the Fine and Gray method. Results The median follow-up duration was 7.7 years (interquartile range, 4.7–13.6 years). Thirty-two (21%) patients experienced disease progression. New organ involvement appeared in 16 patients (11%). The 6-month, and 1-, 5-, 10-, and 15-year cumulative incidence of progression was 2%, 5%, 15%, 28%, and 31%, respectively. The number of organs involved at diagnosis was an independent predictor for progression with a multifactorial adjusted hazard ratio of 1.71 (95% confidence interval, 1.11–2.62). The optimal cut-off of the number of organs involved at diagnosis to identify future progression was three. Conclusions In corticosteroid-naïve sarcoidosis patients, the risks of disease progression are comparable from 0–5 years and 5–10 years after diagnosis. The number of organs involved at diagnosis is a useful predictor for progression of sarcoidosis. PMID:26575272

    What are the consequences of suddenly legalizing fireworks sales in a largely rural society? Would the spectrum of ocular injuries caused by fireworks differ from those found in the Western world? This is the first study on ocular injuries caused by fireworks conducted in the Republic of South Africa. We analyzed the presenting features and prospectively followed up all patients who presented to the casualties served by our ophthalmic department over the New Year celebrations of 1996-1997. The sale of fireworks to the public had been deregulated the previous year. Ocular injuries caused by fireworks had not been reported before 1995. We found that ocular injuries caused by fireworks occurred mainly in young male patients. The injuries were usually unilateral and responded to treatment. This mirrors worldwide studies that show that it is children who are frequently harmed by fireworks injury. Two of our patients were blinded by their injuries. Our findings echo those found in Western countries where fireworks have not been restricted by law. We suggest that young boys, regardless of race, nationality, literacy, or social circumstances, are at risk for ocular injuries caused by fireworks. Countries planning to unban fireworks should aim their education program at this target group.

  11. Purinergic Receptors in Ocular Inflammation

    PubMed Central

    Guzman-Aranguez, Ana; Gasull, Xavier; Diebold, Yolanda; Pintor, Jesús

    2014-01-01

    Inflammation is a complex process that implies the interaction between cells and molecular mediators, which, when not properly “tuned,” can lead to disease. When inflammation affects the eye, it can produce severe disorders affecting the superficial and internal parts of the visual organ. The nucleoside adenosine and nucleotides including adenine mononucleotides like ADP and ATP and dinucleotides such as P1,P4-diadenosine tetraphosphate (Ap4A), and P1,P5-diadenosine pentaphosphate (Ap5A) are present in different ocular locations and therefore they may contribute/modulate inflammatory processes. Adenosine receptors, in particular A2A adenosine receptors, present anti-inflammatory action in acute and chronic retinal inflammation. Regarding the A3 receptor, selective agonists like N6-(3-iodobenzyl)-5′-N-methylcarboxamidoadenosine (CF101) have been used for the treatment of inflammatory ophthalmic diseases such as dry eye and uveoretinitis. Sideways, diverse stimuli (sensory stimulation, large intraocular pressure increases) can produce a release of ATP from ocular sensory innervation or after injury to ocular tissues. Then, ATP will activate purinergic P2 receptors present in sensory nerve endings, the iris, the ciliary body, or other tissues surrounding the anterior chamber of the eye to produce uveitis/endophthalmitis. In summary, adenosine and nucleotides can activate receptors in ocular structures susceptible to suffer from inflammatory processes. This involvement suggests the possible use of purinergic agonists and antagonists as therapeutic targets for ocular inflammation. PMID:25132732

    1999-01-01

    BACKGROUND—The spectrum of diseases caused by Bartonella henselae continues to expand and ocular involvement during this infection is being diagnosed with increasing frequency.
METHODS—The clinical features and visual prognosis for 13 patients with intraocular inflammatory disease and laboratory evidence of bartonellosis were investigated. There were nine patients with neuroretinitis and four with panuveitis with positive antibody titres against B henselae determined by an enzyme immunoassay (IgG exceding 1:900 and/or IgM exceeding 1:250).
RESULTS—Positive IgG levels were found for eight patients and positive IgM levels for five. Despite animal exposure of 10 patients, only two (IgG positive) cases had systemic symptoms consistent with the diagnosis of cat scratch disease. Pathological fluorescein leakage of the optic disc was observed in all affected eyes. At 6 months' follow up, 3/18 (17%) affected eyes had a visual acuity of less than 20/100, owing to optic disc atrophy and cystoid macular oedema. 12 patients (17 eyes) were treated with antibiotics; visual acuity improved two or more Snellen lines for 9/17 (53%) eyes.
CONCLUSIONS—The possibility of B henselae infection should be considered in patients with neuroretinitis and panuveitis (especially in cases with associated optic nerve involvement) even in the absence of systemic symptoms typical for cat scratch disease.

    2013-01-01

    Allergic conjunctivitis (AC) is an inflammation of the conjunctiva secondary to an immune response to exogenous antigens, usually called allergens. In fact, AC is a syndrome that involves the entire ocular surface, including conjunctiva, lids, cornea, and tear film. The signs and symptoms of AC have a meaningful effect on comfort and patient health, and could be influenced by environment, genetics and immune regulation mechanisms, all of which work together in a complex immunological homeostasis. Dysregulation in such immune responses could turn into a variety of ocular allergic diseases (OAD). This review describes some of the current understanding of cellular and molecular pathways involved in different OAD.

    The association between cancer and sarcoidosis is controversial. Some epidemiological studies show an increase of the incidence of cancer in patients with sarcoidosis but only few cases of sarcoidosis following cancer treatment have been reported. We conducted a retrospective case study from internal medicine and oncology departments for patients presenting sarcoidosis after solid cancer treatment. We also performed a literature review to search for patients who developed sarcoidosis after solid cancer. We describe the clinical, biological, and radiological characteristics and outcome of these patients. Twelve patients were included in our study. Various cancers were observed with a predominance of breast cancer. Development of sarcoidosis appeared in the 3 years following cancer and was asymptomatic in half of the patients. The disease was frequently identified after a follow-up positron emission tomography computerized tomography evaluation. Various manifestations were observed but all patients presented lymph node involvement. Half of the patients required systemic therapy. With a median follow-up of 73 months, no patient developed cancer relapse. Review of the literature identified 61 other patients for which the characteristics of both solid cancer and sarcoidosis were similar to those observed in our series. This report demonstrates that sarcoidosis must be considered in the differential diagnosis of patients with a history of malignancy who have developed lymphadenopathy or other lesions on positron emission tomography computerized tomography. Histological confirmation of cancer relapse is mandatory in order to avoid unjustified treatments. This association should be consider as a protective factor against cancer relapse.

    2016-01-01

    Allografts are afforded a level of protection from rejection within immune-privileged tissues. Immune-privileged tissues involve mechanisms that suppress inflammation and promote immune tolerance. There are anatomical features, soluble factors, membrane-associated proteins, and alternative antigen-presenting cells (APC) that contribute to allograft survival in the immune-privileged tissue. This review presents the current understanding of how the mechanism of ocular immune privilege promotes tolerogenic activity by APC, and T cells in response to the placement of foreign antigen within the ocular microenvironment. Discussed will be the unique anatomical, cellular, and molecular mechanisms that lessen the chance for graft destroying immune responses within the eye. As more is understood about the molecular mechanisms of ocular immune privilege greater is the potential for using these molecular mechanisms in therapies to prevent allograft rejection.

    A prospective evaluation of all patients presenting with a sports-related ocular injury during a 1-year (4-season) period was conducted. Of the 202 patients evaluated, 28 (13.8%) required hospitalization and 11 (5.6%) required intraocular surgery. Twenty-six patients (12.8%) sustained permanent ocular sequelae including seven (3.5%) who suffered visual loss. Basketball accounted for 28.7%, baseball/softball 19.8%, and racquetball 11.4% of all injuries. At the time of injury, 5.1% of patients had worn protective eye wear, whereas on follow-up only 31% had used eye protection. These results indicate that sports trauma remains a significant cause of ocular morbidity.

    Background Sarcoidosis is characterised by up-regulation of cytokines and chemokine ligands/receptors and proteolytic enzymes. This pro-inflammatory profile is regulated post-transcriptionally by RNA-binding proteins (RBPs). We investigated in vivo expression of six RBPs (AUF1, HuR, NCL, TIA, TIAR, PCBP2) and two inhibitors of proteolytic enzymes (RECK, PTEN) in pulmonary sarcoidosis and compared it to the expression in four control groups of healthy individuals and patients with other respiratory diseases: chronic obstructive pulmonary disease (COPD), asthma and idiopathic interstitial pneumonias (IIPs). Methods RT-PCR was used to quantify the mRNAs in bronchoalveolar (BA) cells obtained from 50 sarcoidosis patients, 23 healthy controls, 30 COPD, 19 asthmatic and 19 IIPs patients. Flow cytometry was used to assess intracellular protein expression of AUF1 and HuR in peripheral blood T lymphocytes (PBTLs) obtained from 9 sarcoidosis patients and 6 healthy controls. Results Taking the stringent conditions for multiple comparisons into consideration, we consistently observed in the primary analysis including all patients regardless of smoking status as well as in the subsequent sub-analysis limited for never smokers that the BA mRNA expression of AUF1 (p<0.001), TIA (p<0.001), NCL (p<0.01) and RECK (p<0.05) was decreased in sarcoidosis compared to healthy controls. TIA mRNA was also decreased in sarcoidosis compared to both obstructive pulmonary diseases (COPD and asthma; p<0.001) but not compared to IIPs. There were several positive correlations between RECK mRNA and RBP mRNAs in BA cells. Also sarcoidosis CD3+, CD4+ and CD8+ PBTLs displayed lower mean fluorescence intensity of AUF1 (p≤0.02) and HuR (p≤0.03) proteins than control healthy PBTLs. Conclusion mRNA expressions of three RBPs (AUF1, TIA and NCL) and their potential target mRNA encoding RECK in BA cells and additionally protein expression of AUF1 and HuR in PBTLs were down-regulated in our sarcoidosis

    Background Sarcoidosis is a granulomatous disease, the etiology of which is currently unknown. The role of mycobacteria in the etiology of sarcoidosis has been extensively investigated. In this meta-analysis, we assessed the immunological evidence of the possible role of mycobacteria in the pathogenesis and development of sarcoidosis. Methods We performed a systematic search of relevant articles from PubMed, Embase and Cochrane Library databases published between January 1990 and October 2015. Data extracted from the articles were analyzed with Review Manager 5.3 (Cochrane Collaboration, Oxford, UK). Results In this meta-analysis, 13 case-control studies (733 participants) were considered eligible according to our criteria. Methodological quality was assessed using the Newcastle-Ottawa Scale (NOS). The positivity incidence of the immune response (either the cell-mediated response or humoral response) in sarcoidosis patients was significantly higher than that in controls, as determined using fixed-effects model. The odds ratio (OR) of the positivity incidence of T-cell response in the patients with sarcoidosis versus the controls with PPD- or unknown PPD status was 5.54 (95% CI 3.56–8.61); the ORs were 16.70 (95% CI 8.19–34.08) and 1.48 (95% CI 0.74–2.96) for the two subgroups with PPD- controls and unknown PPD status respectively. However, the OR of the positivity incidence in patients with sarcoidosis versus PPD+ controls (latent tuberculosis infection; LTBI) was 0.26 (95% 0.10–0.66). Regarding the humoral response, pooled analysis of the positivity incidence revealed an OR (95%CI) of 20.43 (5.53–75.53) for the patients with sarcoidosis versus controls; the ORs were 11.93 (95% CI 2.15–66.27) and 41.97 (95% CI 5.24–336.15) in two subgroups of controls with PPD- and unknown PPD statuses respectively. Data on heterogeneity and evidence of publication bias were examined. Conclusions This meta-analysis confirmed the existence of an association between

    PURPOSE: This investigation retrospectively examined ocular injuries associated with air bag deployment to gain a better appreciation of potential risk factors in motor vehicle accidents. National statistics regarding the efficacy of air bags were reviewed. METHODS: Review of the literature from 1991 to 1998 identified 44 articles describing 97 patients with air-bag-induced ocular injuries. Variables extracted from each case were age, sex, height, position in the car, eye wear, vehicle impact speed, visual acuity, and specific ocular injuries. RESULTS: Corneal abrasions occurred in 49% of occupants, hyphemas in 43%, vitreous or retinal hemorrhages in 25%, and retinal tears or detachments in 15%. The globe was ruptured in 10 patients. Patients involved in higher-speed accidents (over 30 mph) sustained a greater percentage of vitreous or retinal hemorrhages and traumatic cataracts, while those at slower speeds were more prone to retinal tears or detachments. In a subset of 14 patients with serious ocular injuries, the impact speed of 11 patients was recorded at 30 mph or less. Slower speed may be a risk factor for some ocular injuries. Occupant height was not a significant factor. National statistics confirm that air bags reduce fatalities in motor vehicle accidents. However, children sitting in the front seat without a seat belt and infants in passenger-side rear-facing car seats are at risk for fatal injury. CONCLUSION: Air bags combined with seat belts are an effective means of reducing injury and death in adults during motor vehicle accidents. However, this study has documented a wide variety of ocular injuries associated with air bag deployment. It is hoped that researchers can develop modifications that continue to save lives while minimizing additional harm.

    Cellular characteristics of BAL were investigated in 18 patients with proved extrathoracic sarcoidosis (that is, sarcoidosis that affected the skin, eyes, parotid glands, stomach, nose, kidneys, or meninges) without clinical or radiological mediastinopulmonary involvement. Computed tomography of the thorax was performed on five patients: four patients were normal, and one had enlarged lymph nodes (these enlargements were not detectable on the patient's chest roentgenogram). The results of pulmonary function tests were normal in all patients. The total BAL cell count did not differ significantly between controls and patients. Abnormal percentages of alveolar lymphocytes (from 18 to 87%) were noted in 15 out of 18 patients. SACE levels were normal in 15 patients. No pulmonary gallium uptake was detected. The chemiluminescence of AM's, whether spontaneous or PMA induced, was increased in five out of seven patients. The percentages of T3+ lymphocytes in sarcoidosis patients did not significantly differ from those in controls. The T4+:T8+ ratio was normal in four patients and slightly increased in one. Follow-up of patients showed that alveolar lymphocytosis is as lasting as extrathoracic involvement. Our data demonstrate increased percentages of lymphocytes and activated AM's in the BAL of patients with extrathoracic sarcoidosis. This may be due to the initial involvement of the respiratory tract in extrathoracic sarcoidosis or to the diffusion of activated macrophages and lymphocytes from an extrathoracic site into the lung.

    Patient: Male, 26 Final Diagnosis: Sarcoidosis Symptoms: Disseminated lung parenchymal changes Medication: — Clinical Procedure: — Specialty: Pulmonology Objective: Rare disease Background: Sarcoidosis is a granulomatous inflammatory disease that is induced by unknown antigen(s) in a genetically susceptible host. Although the direct link between Mycobacterium tuberculosis (MTB) infection and sarcoidosis can be excluded on the basis of a current knowledge, the non-infectious mechanisms may explain the causative role of mycobacterial antigens. The co-incidence of tuberculosis (TB) and sarcoidosis, and higher incidence of mycobacterial DNA in biological samples of sarcoid patients, have been reported by many authors. Case Report: We present a case in which MTB infection in 1 family member triggered a sarcoid reaction in the infected subject and 2 other non-infected family members. We discuss different aspects of diagnosis and differentiation, as well as up-to-date hypotheses on the possible mechanisms leading to sarcoid inflammation in patients exposed to MTB. Conclusions: This case series documents the possibility of familial spreading of sarcoidosis, and points to MTB as a potential etiological factor. PMID:24847413

    Sarcoidosis is a systemic disease of unknown etiology that may affect any organ in the body. The nervous system is involved in 5-16% of cases of sarcoidosis. Here, we report a case of intramedullary sarcoidosis presenting with delayed spinal cord swelling after laminoplasty for the treatment of compressive cervical myelopathy. A 56-year-old woman was admitted to our hospital complaining of upper extremity pain and gait disturbance. The patient had undergone laminoplasty for compressive cervical myelopathy 3 months previously. Follow-up magnetic resonance imaging revealed a large solitary intramedullary lesion with associated extensive cord swelling, signal changes, and heterogeneous enhancement of spinal cord from C2 to C7. Spinal cord biopsy revealed non-necrotizing granulomas with signs of chronic inflammation. The final diagnosis of sarcoidosis was based upon laboratory data, imaging findings, histological findings, and the exclusion of other diagnoses. Awareness of such presentations and a high degree of suspicion of sarcoidosis may help arrive at the correct diagnosis. PMID:25535524

    A number of adhesion molecules participate in the recruitment of inflammatory cells to the site of inflammation, and selectins together with their ligands are important in the early transient adhesion phase. In this study, we evaluated the role of L-selectin in T lymphocyte alveolitis in patients with active pulmonary sarcoidosis. We measured serum and bronchoalveolar lavage fluid (BALF) concentrations of soluble (s)L-selectin using an ELISA. Serum and BALF concentrations of sL-selectin were significantly elevated in patients with sarcoidosis compared with control healthy subjects and idiopathic pulmonary fibrosis (IPF) patients (P < 0.05 and P < 0. 01, respectively). The lymphocyte surface marker was also examined in peripheral blood and BALF by flow cytometric analysis. The percentage of CD3+CD62L+ cells (L-selectin-bearing T lymphocytes) was significantly lower in peripheral blood of sarcoidosis than in that of healthy subjects (P < 0.01). In contrast, the percentage of CD3+CD62L- cells (L-selectin-negative T lymphocytes) in BALF of patients with sarcoidosis was significantly higher than in healthy subjects (P < 0.05) and IPF patients (P < 0.01). Furthermore, there was a significant correlation between serum concentrations of sL-selectin and the number of L-selectin-negative T lymphocytes in BALF (r = 0.535, P < 0.01). Our results suggest that L-selectin may be involved in T lymphocyte alveolitis in patients with active pulmonary sarcoidosis. PMID:10886252

  5. Evaporation from the ocular surface.

    PubMed

    Mathers, William

    2004-03-01

    Evaporation from the ocular surface is dramatically reduced by the lipid layer which covers it. With this layer intact, evaporation represents a small loss of water for which the lacrimal gland easily compensates. When tear production is compromised evaporation becomes important, especially since evaporation in almost all ocular surface disease states and any surface perturbation, including contact lens wear, increases evaporation significantly. How the barrier function of the lipid layer accomplishes this reduction in evaporation is not understood and is probably quite complex as is the structure of the lipid layer. Improving this barrier function remains an important and elusive goal.

    Vaccinations are very effective measures for prevention of infections but are also associated with a long list of possible side effects. Adverse ocular effects following vaccination have been rarely reported or considered to be related to vaccinations. Conjunctivitis is a frequent sequel of various vaccinations. Oculorespiratory syndrome and serum sickness syndrome are considered to be related to influenza vaccinations. The risk of reactivation or initiation of autoimmune diseases (e. g. uveitis) cannot be excluded but has not yet been proven. Overall the benefit of vaccination outweighs the possible but very low risk of ocular side effects.

    We discuss the case of a 38-year-old black man who presented at our hospital with his first episode of syncope, recently developed atrial arrhythmias refractory to pharmacologic therapy, and a left atrial thrombus. He was diagnosed with primary cardiac sarcoidosis characterized by predominant involvement of the epicardium that caused atrial fibrillation and atrial flutter. Histologic analysis of his epicardial lesions yielded a diagnosis of sarcoidosis. This patient's atrial arrhythmia was successfully treated with a hybrid operation that involved resection of his atrial appendage, an Epicor maze procedure, and radiofrequency ablation during a catheter-based electrophysiologic study. The cardiac sarcoidosis was successfully managed with corticosteroid therapy. Our case report shows that sarcoidosis can initially manifest itself as syncope with new-onset atrial arrhythmia. Sarcoidosis is important in the differential diagnosis because of its progressive nature and its potential for treatment with pharmacologic, surgical, and catheter-based interventions. PMID:27303240

    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.

    Early diagnosis of cardiac sarcoidosis remains difficult in the absence of specific symptoms. The evolution and prognosis of the disease are strongly correlated to an early and appropriate treatment. The multi-modality assessment based on cardiac MRI and positron emission tomography associated with computed tomography (PET/CT) has significantly improved the detection of cardiac sarcoidosis over the last two decades. These approaches appear as useful and suitable imaging strategy for the early diagnosis, the assessment of the disease extent as well as the management and therapeutic follow-up. This article is a didactic review on cardiac sarcoidosis, with a special focus on recent diagnostic and therapeutic modalities, prognosis and interest of imaging techniques.

    We correlated the results of parotid gland biopsy, chest roentgenograms, and gallium citrate scintigraphy in 24 patients evaluated for possible systemic sarcoidosis. Of 19 patients ultimately proven to have sarcoidosis, 11 (57.9 percent) had positive parotid gland biopsy. The yield of parotid gland biopsy in patients with abnormal gallium parotid activity was only marginally higher (64.7 percent). Abnormal parotid gland uptake of gallium citrate was seen in 17 of these 19 patients (89.5 percent) and was always associated with abnormal lung or perihilar activity. The parotid gland biopsy is a useful technique for obtaining the tissue diagnosis of sarcoidosis; however, gallium scintigraphy should not be performed to select patients as this will only marginally increase the biopsy yield.

In the past he had undergone two angioplasties, multiple stenting, and a triple aorto-coronary bypass. The patient also experienced a painful enlargement of the thyroid gland with bilateral multiple lymphoadenopathies and thyrotoxicosis. Thyroid histology revealed interstitial non-caseating granulomas that are typical of thyroid sarcoidosis. The finding ofgranulomas in the thyroid allowed us to interpret the clinical manifestations of our patient leading to the diagnosis of sarcoidosis.

    We describe a rare case of recurrent laryngeal nerve neuritis secondary to sarcoidosis. A 40-year-old woman presented with persistent dysphonia. This was her first episode of dysphonia with no reports of laryngeal trauma. Fibre-optic laryngoscopy revealed a normal nasal passage, nasopharynx and pharynx. The supraglottic structures were all unremarkable; however, inspection of the true vocal cords revealed a left vocal cord palsy that was identified as being in a paramedian position. Radiological investigation showed mediastinal adenopathy that measured up to 20 mm in the short axis diameter. Histological examination showed granulomatous lymphadenitis of the lymph node with a central area of sclerosis surrounded by discrete, non-caseating granuloma. Stains for acid-fast bacilli were negative. The morphological features were suggestive of sarcoidosis. The lymphadenopathy distribution and size did not suggest left recurrent laryngeal nerve compression, giving a subsequent diagnosis of recurrent laryngeal nerve neuritis secondary to sarcoidosis.

Ocular disease associated with viral pathogens is not unusual, particularly with viruses causing upper respiratory tract disease in cats, such as feline herpesvirus type 1 and feline calicivirus. These agents mainly cause ocular surface disease. Other viruses, such as feline immunodeficiency virus and feline coronavirus, can cause uveitis, while feline leukemia virus can induce ocular lymphosarcoma.

    Purpose The purpose of this study is to describe a case of ocular rosacea with a very complex evolution. Rosacea is a chronic dermatological disease that may affect the ocular structures up to 6-72% of all cases. This form is often misdiagnosed, which may lead to long inflammatory processes with important visual consequences for affected patients. Therefore, an early diagnosis and an adequate treatment are important. Methods We report the case of a 43-year-old patient who had several relapses of what seemed an episode of acute bacterial conjunctivitis. Two weeks later, he developed a corneal ulcer with a torpid evolution including abundant intrastromal infiltrators and calcium deposits. He was diagnosed with ocular rosacea and treated with systemic doxycycline and topical protopic. Results A coating with amniotic membrane was placed in order to heal the ulcer, but a deep anterior lamellar keratoplasty to restore the patient's vision because of the corneal transparency loss was necessary. Conclusions Ocular rosacea includes multiple ophthalmic manifestations ranging from inflammation of the eyelid margin and blepharitis to serious corneal affectations. A delayed diagnosis can result in chronic inflammatory conditions including keratinization and loss of corneal transparency, which lead to important visual sequelae for affected patients.

    Takayasu arteritis (TA) is a rare manifestation of systemic large vessel vasculitis which affects predominantly the aorta and its main branches, but often remains unrecognised owing to delayed diagnosis and non-characteristic clinical features. Sarcoidosis, too, is a systemic inflammatory disease which can affect virtually any organ system. Reports about the coincidence of both diseases have appeared.
  The case presented here is characterised by a significant time lag between detection of TA and appearance of clinical signs of sarcoidosis. The woman, now 39 years old, had erythema nodosum, circumscript alopecia, and recurrent uveitis, which dated back to 1980 and was attributed to sarcoidosis. At least 12 years later aortic valve insufficiency with progressive cardiac failure developed. Histology performed at the time of aortic valve prosthesis in 1997 disclosed a diagnosis of TA, which was confined to the aortic root. Incidentally, sarcoidosis was diagnosed in adjacent lymph nodes. A thorough check up failed to detect further manifestations of TA; thus, possibly, the patients had aortitis similar to, but not identical with, TA.
Several related cases previously reported are discussed, suggesting that both diseases may be inherently related as they are characterised by certain non-specific, immunoinflammatory abnormalities. This case report suggests that the prevalence of TA, or related forms of arteritis, may be higher than expected and should be considered, especially in younger patients with non-characteristic cardiovascular symptoms and suspected systemic inflammatory disease. Moreover, the association with sarcoidosis in this and other previously described cases suggests that the two diseases may be related and that TA or TA-like vasculitis may even be a complication of sarcoidosis.

    Background Studies have reported a high diagnostic yield of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for the diagnosis of sarcoidosis. We sought to review the yield of EBUS-TBNA for the diagnosis of sarcoidosis at our institution over time, and examine factors that may influence this yield. Methods Patients who underwent EBUS-TBNA for suspected sarcoidosis between December 2008 and November 2011 were identified. EBUS was performed without rapid on-site evaluation (ROSE) of samples. The final diagnosis was based on the results of all invasive diagnostic procedures and/or clinical follow-up. Logistic regression analysis was used to examine the effect of various factors on yield. Results 43 patients underwent 45 EBUS-TBNA procedures for suspected sarcoidosis. A total of 115 lymph nodes were sampled. The 21 G needle was used in 51% of procedures. The mean number of lymph node stations sampled was 2.6 (SD 0.7) and the mean number of needle passes per procedure was 7.8 (SD 2.0). Non-necrotising granulomatous inflammation was detected in EBUS-TBNA samples from 34/45 (76%) procedures. The overall diagnostic yield increased to 36/45 (80%) following a cytopathology review for this study. Needle gauge, number of lymph node stations sampled and number of needle passes were not associated with diagnostic yield. The yield of EBUS-TBNA increased significantly after the first 15 procedures performed for suspected sarcoidosis; the 2 additional cases diagnosed after the cytopathology review were part of this early experience. Conclusions EBUS-TBNA is a valuable technique for the diagnosis of sarcoidosis when performed without ROSE. The yield of the procedure improved significantly over time, based on operator and cytopathologist experience. PMID:27547408

    Sarcoidosis disease expression differs along racial/ethnic lines and black race has been cited as a poor prognostic factor. Besides genetic, healthcare, and socioeconomic factors, comorbid illnesses may influence sarcoidosis disease expression. We set out to investigate the association between comorbid illnesses and chest radiographic severity in a population of African-American sarcoidosis patients. The study was designed as a retrospective database analysis. The hospital and outpatient databases of the Grady Health System were searched to capture adult patients between November 1999 and December 2003 with the ICD-9 codes of 135 or 519.8, along with all associated secondary and tertiary diagnostic codes. Patient electronic pathology and radiographic reports were reviewed for tissue biopsies showing noncaseating granulomas and for chest radiographic Scadding stage. A total of 165 African-American patients were identified (64% female, 43 +/- 10 years old). Ninety percent (149/165) had comorbid illnesses. The most frequent chronic comorbid illnesses were hypertension (39%), diabetes mellitus (19%), anemia (19%), asthma (15%), gastroesophageal reflux disease (15%), depression (13%), and heart failure (10%). Females had increased frequency and clustering of chronic illnesses. Chest radiographic stages were more severe in patients with anemia, depression, and those less than 40 years old. Males, within each chronic illnesses category, had more severe CXR stages compared to females; however, significance was not achieved. We concluded that most adult patients with sarcoidosis have comorbid illnesses and these, in addition to gender differences, may influence sarcoidosis disease expression. Screening for comorbid illnesses should be an important aspect of sarcoidosis patient management.

    An unusual case of a patient with a long-standing fever of unknown origin (FUO) is presented whose gallium-67 ({sup 67}Ga) images revealed increased activity only in the calf muscles bilaterally. Other imaging modalities also failed to show chest or other abnormal findings. Subsequent biopsy of the right gastrocnemius muscle revealed noncaseating granulomas consistent with the diagnosis of sarcoidosis. When using {sup 67}Ga to evaluate a patient with a FUO, imaging of the extremities should always be included. Also, when abnormal Ga-67 uptake is present in the extremities, sarcoidosis should be included in the differential diagnosis.

    Results of bronchoalveolar lavage (BAL), 67Ga scanning, and serum angiotensin-converting enzyme (SACE) assay are compared in the assessment of pulmonary involvement in ten cases of extrathoracic sarcoidosis. Standard clinical, radiologic, and pulmonary function tests detected no pulmonary changes in these patients, but BAL demonstrated an increased alveolar lymphocytosis in eight of ten cases. SACE levels were increased in two cases, and the thoracic gallium uptake was normal in all cases. BAL appears to be the best technique for diagnosing latent pulmonary involvement in extrathoracic sarcoidosis.

    We have described three patients with clinical evidence of myocardial sarcoidosis to illustrate the utility of thallium-201 scintigraphy in demonstrating the myocardial lesions. Both the symptomatic and asymptomatic individuals studied showed the characteristic reverse redistribution phenomenon. No abnormalities were seen during the exercise phase of the thallium study, but myocardial defects were detected in each patient when repeat studies were obtained at rest six hours later. Steroid therapy resolved the defects in each case. We propose thallium-201 scintigraphy of the heart as a safe and useful tool for documenting myocardial involvement in sarcoidosis and following the effects of therapy.

    The authors describe a 38-year-old man who was referred to the nuclear medicine department because of pain and swelling of his fingers in both hands. Tc-99m MDP and Tl-201 scans were performed to evaluate the lesions. A Tc-99m MDP bone scan showed hyperemia and increased uptake in the lesions. A Tl-201 scan showed marked uptake in both early and delayed images in the lesions of his fingers. Bone biopsy and histologic examination confirmed sarcoidosis. This case indicates that Tl-201 uptake can be seen in bone lesions resulting from sarcoidosis. PMID:11353294

    Anti-TNF-alpha agents have been tried in cases of refractory sarcoidosis, giving favourable results. Thus, the occurrence of a granulomatous disease in a patient receiving such drug seems paradoxical. We describe 2 patients with inflammatory rheumatic disease, the first with ankylosing spondylitis, the second with rheumatoid arthritis, under anti-TNF-alpha treatment (infliximab and etanercept respectively) who developed non-caseating granulomas of the lungs and lymph nodes consistent with the diagnosis of sarcoidosis. Limited and various similar cases have been reported. It is generally considered that these granulomatous diseases are related to the anti-TNF-alpha agent.

    Sarcoidosis is a benign systematic granulomatous disorder of unknown etiology and is associated with various malignancies. However, granulomatous and metastatic lymph node lesions are difficult to distinguish even when using precise and modern diagnostic methods, such as positron emission tomography. Thus, histological verification is the only method that can be used to accurately describe the nature of this disease. In this article, we report a case of non-luminal HER-2/neu-positive breast cancer in a patient without history of sarcoidosis and suspected to have metastatic disease. PMID:27807507

    The paper is devoted to an analysis of combined x-ray findings supplemented by CT findings in patients with sarcoidosis detected for the first time with early signs of this disease. A conclusion has been made that apart from lymph node enlargement, sarcoidosis is characterized by lung parenchymal changes which manifest themselves as symptoms of broncho-alveolitis. Characteristic x-ray symptom complexes are described. Roentgeno-semiotics of these changes were compared with the results of morphological investigation of transbronchial puncture specimens. Roentgenologically detectable changes showed good correlation with morphology findings. The authors have also emphasized the importance of morphological verification of this disease at early stages.

    OBJECTIVE: To evaluate the frequency of ocular complications and the clinical outcomes of these complications in patients with various stages of HIV infection. METHODS: Retrospective review of all HIV-infected patients seen in an AIDS ophthalmology clinic from November 1983 through December 31, 1992. RESULTS: Eleven-hundred sixty-three patients were seen for ophthalmologic evaluation. Of these, 781 had the acquired immune deficiency syndrome (AIDS), 226 had symptomatic HIV infection (AIDs-related complex [ARC]), and 156 had asymptomatic HIV infection. Non-infectious HIV retinopathy was the most common ocular complication, affecting 50% of the patients with AIDS, 34% of the patients with ARC, and 3% of the patients with asymptomatic HIV infection. Cytomegalovirus (CMV) retinitis was the most common opportunistic ocular infection, affecting 37% of the patients with AIDS. Other opportunistic ocular infections, including ocular toxoplasmosis, varicella zoster virus retinitis, and Pneumocystis choroidopathy were all much less common, each occurring in < or = 1% of the patients with AIDS. Treatment of CMV retinitis with either foscarnet or ganciclovir was successful in initially controlling the retinitis. However, relapse represented a significant problem and required frequent re-inductions. As a consequence of the retinal damage associated with relapse, loss of visual acuity occurred. The median time to a visual acuity of 20/200 or worse for all eyes with CMV retinitis was 13.4 months, and the median time to a visual acuity of 20/200 or worse in the better eye was 21.1 months. At last follow-up, 75% of the patients had a final visual acuity of 20/40 or better in at least one eye. Retinal detachments were a frequent ophthalmologic complication of CMV retinitis with a cumulative probability of a retinal detachment in at least one eye of 57% at 12 months after the diagnosis of CMV retinitis. Herpes zoster ophthalmicus developed in 3% of the overall series and was seen in

We describe three cases in which ocular foreign bodies have masqueraded as ocular malignant melanoma. Methods Interventional case reports. Results Case 1 describes diathermy-induced carbon particle implantation, during plaque therapy for the treatment of uveal melanoma, mimicking recurrence with extra-scleral invasion. Case 2 shows a foreign body called ‘mullite' mimicking conjunctival melanoma. Case 3 demonstrates a conjunctival foreign body called ‘illite' that mimicked a limbal melanocytic lesion, clinically thought to be either melanocytoma or melanoma. Conclusion This report highlights the importance of careful history taking, examination, and appropriate biopsy in cases of suspected malignant melanoma, to prevent unnecessary and potentially radical treatment.

    Background Sarcoidosis is an idiopathic granulomatous disease with pathologic and immunologic features similar to tuberculosis. Routine histologic staining and culture fail to identify infectious agents. An alternative means for investigating a role of infectious agents in human pathogenesis involves molecular analysis of pathologic tissues for microbial nucleic acids, as well as recognition of microbial antigens by the host immune system. Molecular analysis for superoxide dismutase A (sodA) allows speciation of mycobacteria. SodA is an abundantly secreted virulence factor that generates cellular immune responses in infected hosts. The purpose of this study is to investigate if target antigens of the sarcoidosis immune response can be identified by molecular analysis of sarcoidosis granulomas. Methods We detected sodA amplicons in 12 of 17 sarcoidosis specimens, compared to 2 of 16 controls (p = 0.001, two-tailed Fisher's exact test), and 3 of 3 tuberculosis specimens (p = 0.54). Analysis of the amplicons revealed sequences identical to M. tuberculosis (MTB) complex, as well as sequences which were genetically divergent. Using peripheral blood mononuclear cells (PBMC) from 12 of the 17 sarcoidosis subjects, we performed enzyme-linked immunospot assay (ELISPOT) to assess for immune recognition of MTB sodA peptides, along with PBMC from 26 PPD- healthy volunteers, and 11 latent tuberculosis subjects. Results Six of 12 sarcoidosis subjects recognized the sodA peptides, compared to one of 26 PPD- controls (p = 0.002), and 6/11 PPD+ subjects (p = .68). Overall, 10 of the 12 sarcoidosis subjects from whom we obtained PBMC and archival tissue possessed molecular or immunologic evidence for sodA. Conclusion Dual molecular and immunologic analysis increases the ability to find infectious antigens. The detection of Th-1 immune responses to sodA peptides derived from molecular analysis of sarcoidosis granulomas reveals that these are among the target antigens contributing to

  16. Ocular effects of radiofrequency energy.

    Elder, J A

    2003-01-01

    Radiofrequency (RF) energy has been reported to cause a variety of ocular effects, primarily cataracts but also effects on the retina, cornea, and other ocular systems. Cataracts have been observed in experimental animals when one eye was exposed to a localized, very high RF field and the other eye was the unexposed control. The results show that 2450 MHz exposures for >or=30 min at power densities causing extremely high dose rates (>or=150 W/kg) and temperatures (>or=41 degrees C) in or near the lens caused cataracts in the rabbit eye. However, cataracts were not observed in the monkey eye exposed to similar exposure conditions, reflecting the different patterns of energy absorption (SAR, specific absorption rate) distribution, due to their different facial structure. Since the monkey head is similar in structure to the human head, the nonhuman primate study showed that the incident power density levels causing cataracts in rabbits and other laboratory animals cannot be directly extrapolated to primates, including human beings. It is reasonable to assume that an SAR that would induce temperatures >or=41 degrees C in or near the lens in the human eye would produce cataracts by the same mechanism (heating) that caused cataracts in the rabbit lens; however, such an exposure would greatly exceed the currently allowable limits for human exposure and would be expected to cause unacceptable effects in other parts of the eye and face. Other ocular effects including corneal lesions, retinal effects, and changes in vascular permeability, have been observed after localized exposure of the eye of laboratory animals to both continuous wave (CW) and pulsed wave (PW) exposures, but the inconsistencies in these results, the failure to independently confirm corneal lesions after CW exposure, the failure to independently confirm retinal effects after PW exposure, and the absence of functional changes in vision are reasons why these ocular effects are not useful in defining an

    Ocular Toxocariasis is a parasitosis caused by Toxocara catis/canis larvae localized in the eye. The most frequent clinical manifestations are the central retinal granuloma, peripheral retinal granuloma and chronic endophthalmitis. Secondary complications due to the presence of parasite in the posterior segment of the eye may have significant consequences on visual function. We present the case of a 23 years old patient, admitted for progressive decrease of the right eye BCVA during the last 6 months. After performing clinical examination and serological tests we established the diagnosis of ocular Toxocariasis. The patient presented a particular form of the disease consisting in the presence of both a central retinal granuloma and a peripheral one. We performed 23G pars plana vitrectomy and membrane peeling. VA improved as soon as the first month after surgery.

    We describe 16 cases of ocular and, in some patients, associated CNS toxoplasmosis in AIDS patients. T gondii is commonly associated with infection in the immunocompromised host. The lesions are most often seen in the CNS and eyes; involvement in the brain, heart, lung, liver, spleen, and lymph nodes may be observed. CNS involvement by toxoplasmosis may be an initial manifestation of AIDS and may be associated with discrete or diffuse lesions. CT scan and MR imaging may demonstrate a multitude of lesions often displaying the characteristic ring-shaped enhancement after contrast injection. Ocular involvement by toxoplasmosis, though less common than CNS involvement, is characterized by several features. These may be manifested as single or multifocal retinal lesions in one or both eyes or massive areas of retinal necrosis. Invariably these lesions are unassociated with a pre-existing retinochoroidal scar suggesting that the lesions are a manifestation of acquired rather than congenital disease. Presence of IgM antibodies may support this observation although antibody levels in AIDS patients may not reflect the magnitude of disease. Vitreous reaction is often minimal. Anterior uveitis has been reported in one case. Treatment of the ocular infection with pyrimethamine, clindamycin and sulfadiazine is effective in over 75% of patients. Once resolution of the ocular infection is observed, maintenance therapy is continued as relapses occur in the absence of treatment. Corticosteroid treatment is unnecessary and its use has been associated with the development of CMV retinitis. Other retinal infections in AIDS patients which should be considered in the differential diagnosis include CMV, herpetic-associated ARN and syphilis. Concomitant CMV and toxoplasmosis in the same eye have been seen.

    HSCT has been linked to the development of an assortment of ocular surface complications with the potential to lead to permanent visual impairment if left untreated or if not treated early in the course of disease. Strategies for therapy include maintenance of lubrication and tear preservation, prevention of evaporation, decreasing inflammation, and providing epithelial support. The ultimate aim of treatment is to prevent permanent ocular sequelae through prompt ophthalmology consultation and the use of advanced techniques for ocular surface rehabilitation.

    Torticollis can arise from nonocular (usually musculoskeletal) and ocular conditions. Some facial asymmetries are correlated with a history of early onset ocular torticollis supported by the presence of torticollis on reviewing childhood photographs. When present in an adult, this type of facial asymmetry with an origin of ocular torticollis should help to confirm the chronicity of the defect and prevent unnecessary neurologic evaluation in patients with an uncertain history. Assessment of facial asymmetry consists of a patient history, physical examination, and medical imaging. Medical imaging and facial morphometry are helpful for objective diagnosis and measurement of the facial asymmetry, as well as for treatment planning. The facial asymmetry in congenital superior oblique palsy is typically manifested by midfacial hemihypoplasia on the side opposite the palsied muscle, with deviation of the nose and mouth toward the hypoplastic side. Correcting torticollis through strabismus surgery before a critical developmental age may prevent the development of irreversible facial asymmetry. Mild facial asymmetry associated with congenital torticollis has been reported to resolve with continued growth after early surgery, but if asymmetry is severe or is not treated in the appropriate time, it might remain even with continued growth after surgery.

    Ocular drug therapy has always been considered as a major challenge in the field of drug delivery. The presence of blood ocular barriers and efflux pumps has imposed a great concern as well. Various vision threatening disorders require a long term therapy of drug molecules, especially for the diseases that affect the posterior segment. Pharmaceutical companies and other research institutes have adopted a multidisciplinary approach to meet the current challenges which is evidenced by the trends seen in the published and filed U.S. patents. Various strategies have been employed to achieve long term sustained and targeted delivery for both the anterior and the posterior segments of the ocular diseases. These strategies include formulating drugs into implant, micro or nanoparticulate systems and hydrogel-based systems. Transporter targeted approach has also allowed scientists to deliver drugs to both the segments of the eye. Recent developments such as delivery of drugs utilizing ultrasound, iontophoresis and microneedle based devices have been promising. Gene-based therapeutics has opened a new avenue for vision threatening disorders. In all, the current developments in the entire field have been very exciting for finding out new strategies to treat vision threatening disorders. PMID:22493994

    Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome (ACS), cardiac tamponade and sudden cardiac death that typically affects young women in the postpartum period. Rarely, it can be caused by systemic inflammatory conditions such as sarcoidosis. Sarcoidosis is an inflammatory disease most often affecting the lung and lymph nodes that can sometimes affect the heart. The authors report a case of sudden cardiac death caused by SCAD in the context of undiagnosed and subclinical cardiac sarcoidosis. The decedent was a 47-year-old male with a relatively innocuous past medical history. He was found dead in bed. At autopsy, there was a lethal hemopericardium resulting in cardiac tamponade. Gross examination of the heart revealed dissection of the posterior descending coronary branch of the right coronary artery. Histologically, the coronary artery showed acute and organizing dissection with evidence of vasculitis. A chronic inflammatory infiltrate consisting of lymphocytes, histiocytes, eosinophils and giant cells was seen. Sections of the myocardium showed myocarditis with a nonnecrotizing granuloma. The death was attributed to cardiac tamponade secondary to SCAD in the context of systemic sarcoidosis. The presented case demonstrates two concurrent rare pathologies and highlights the importance of considering SCAD in cases of sudden cardiac death at autopsy.

    Obstruction of the thoracic duct may lead to accumulation of a lymphatic fluid rich in triglycerides named chyle. When chyle accumulates in the pleural cavity, it becomes a chylothorax. Malignancy, particularly lymphoma, is the most common cause of chylothorax; however, any pathology leading to obstruction or destruction of the thoracic duct can lead to a chylothorax. This particular case investigates an incidence of chylothorax in sarcoidosis. A 54-year-old African American woman with a medical history of sarcoidosis, congestive heart failure, and smoking presented to the emergency department with complaints of bilateral foot swelling and exertional shortness of breath 3 days in duration. Physical examination was positive for bilateral crepitations with decreased air entry, abdominal ascites, and bilateral 2+ pitting edema. Both chest X-ray and chest CT were positive for stable bilateral pleural effusions (when compared to imaging done 3 years previously), and thoracocentesis and paracentesis were positive for chylous fluid accumulation. Chylothorax was diagnosed, and based on the previous medical history, the lymphadenopathy of sarcoidosis was determined to cause the occlusion of the thoracic duct. Lymphoscintigraphy and surgical intervention were advised; however, the family decided on conservative management and the patient expired intubated in the ICU. Chylothorax is a rare manifestation of sarcoidosis and high index of suspicion should be there to diagnose this, as there is high morbidity and mortality associated with it. PMID:26333861

    Diagnostics of intrathoracic sarcoidosis in people with an occupational injury or an annoyance of respiratory organs are frequently connected with additional difficulties. The first roentgenological manifestations of a silicosis caused during the period of dry drilling especially in ore metal mining, are frequently bilaterally increased shadows of the hilum without any worth mentioning findings in the parenchyma. The radiograph of diffuse restiform and speckled shadows in people exposed to dust without a sufficient load or in younger age always demands a search for sarcoidosis. Granulomatoses of the lungs caused by organic dusts, berillium and other things may develop difficulties not only in the interpretation of clinical data but also in the bioptic findings for instance after an endoscopic antalgic biopsy of the bronchomucosa. The authors summarize their experiences with the application of bioptic methods (skin biopsy, according to the Kveim-test, scalenobiopsy, explorative thoracotomy) in workers suspected to suffer from a sarcoidosis, who--as to their profession--had been influenced by noxious substances in respect to their lungs. Two typical cases are briefly discussed. The signification of the synopsis of clinico roentgenological, industriohygienical and bioptical data is stressed especially in case of a suspicion on the combination of pneumoconiosis and sarcoidosis.

When dermal changes are suspected of sarcoidosis, a dermatologist should examine the patient and, if there are some doubts about the nature of dermal elements, biopsy and histological study should be made since the morphological verification of the diagnosis primarily requires the use of extrapulmonary sites of the process, namely superficial peripheral lymph nodes, as well as the skin. The findings suggest that skin sarcoidosis characterized by the long-term chronic or progressive course is encountered at different (X-ray) stages of sarcoidosis of respiratory organs and is of poor prognostic value. The severity of dermal manifestations is no less and, in individual cases, more significant than pulmonary symptoms. Great or ugly skin lesions require prednisolone treatment. In some cases, long-term therapy cannot yield a result. Delagil treatment of dermal manifestations remains to be effective.

    A 62-year-old woman with skin sarcoidosis was admitted to our hospital to ascertain whether she had cardiac involvement. Although she displayed no cardiac signs or symptoms, the electrocardiogram showed first-degree atrioventricular block, right bundle branch block with left anterior fascicular block, and giant negative T waves in the V3 lead. Echocardiography revealed marked hypertrophy localized in the basal portion of the interventricular septum (IVS) without systolic dysfunction, mimicking hypertrophic cardiomyopathy (HCM). Exercise thallium-201 myocardial imaging revealed redistribution in the anteroseptal region. Both gallium-67 (67Ga) and technetium-99m pyrophosphate (99mTc-PYP) scintigraphy revealed abnormal uptake in the myocardium. These findings disappeared after 2 months of steroid treatment. Reports of cardiac sarcoidosis mimicking HCM are rare. However, hypertrophy in the basal portion of the IVS is an important sign of early cardiac involvement in sarcoidosis. 67Ga and 99mTc-PYP scintigraphy were useful and necessary to differentiate this type of cardiac sarcoidosis from HCM.

    Background and Objectives. Sarcoidosis is an inflammatory disease with increased levels of inflammatory cytokines. Previous studies have shown a relation between the degree of granuloma infiltration and serum cytokine levels, except for interleukin- (IL-) 10. The aim of the study was to further investigate the serum levels of IL-10 in patients with sarcoidosis and relate them to fungal exposure in terms of the amount of fungi in the air of their homes and β-glucan in bronchoalveolar lavage (BAL) fluid. Methods. Patients with sarcoidosis (n = 71) and healthy controls (n = 27) were enrolled. IL-10 was determined in serum. BAL was performed and the amount of β-glucan was measured. Domestic exposure to fungi was determined by measuring airborne β-N-acetylhexosaminidase (NAHA) in the bedrooms. Results. At high levels of fungal exposure (domestic fungal exposure and β-glucan in BAL), serum IL-10 values were lower than at low and intermediate exposure levels. Conclusion. The low serum IL-10 values at high fungal exposure suggest that fungal cell wall agents play a role in granuloma formation in sarcoidosis by inhibiting the secretion of the anti-inflammatory cytokine IL-10.

    Sarcoidosis is a multi-systemic inflammatory disease of unknown origin characterized by the presence of noncaseating epitheloid cell granulomas in multiple organs. Diagnosis is made on the basis of a compatible clinical-radiological scenario and the histological demonstration of the typical granulomas in the affected tissues. Interferons are immuno-modulators that have been used in a wide range of diseases, including hepatitis C virus infection, multiple sclerosis, and multiple myeloma and other types of tumours, including leukemia, lymphomas, Kaposi's sarcoma, and melanoma. Interferon-alpha-induced sarcoidosis has been reported repeatedly and there are two reports in the literature of cases of pulmonary sarcoidosis treated with interferon-1b therapy: one for advanced renal cell carcinoma and the other for multiple myeloma. A 35-year-old man on chronic immune-modulant Interferon-1b-based therapy for multiple sclerosis presented to the Neurology Unit with mild dyspnoea, dry cough, and transient pain to right upper abdomen. Lungs, spleen, liver, and almost all lymphnode stations of abdomen and mediastinum were clearly involved on ultrasound examination, chest X-ray, and computed tomography. A transbronchial biopsy showed non-caseating granuloma on histopathologic evaluation of the lungs. To the best of our knowledge, this is the first report of a chronic multisystemic sarcoidosis that was associated with interferon-beta treatment.

    Purpose/Objectives To review common tyrosine kinase inhibitors, as well as their ocular side effects and management. Data Sources A comprehensive literature search was conducted using cINahl®, Pubmed, and cochrane databases for articles published since 2004 with the following search terms: ocular toxicities, tyrosine kinase inhibitors, ophthalmology, adverse events, eye, and vision. Data Synthesis Tyrosine kinase inhibitors can cause significant eye toxicity. Conclusions Given the prevalence of new tyrosine kinase inhibitor therapies and the complexity of possible pathogenesis of ocular pathology, oncology nurses can appreciate the occurrence of ocular toxicities and the role of nursing in the management of these problems. Implications for Nursing Knowledge of the risk factors and etiology of ocular toxicity of targeted cancer therapies can guide nursing assessment, enhance patient education, and improve care management. Including a review of eye symptoms and vision issues in nursing assessment can enhance early detection and treatment of ocular toxicity. PMID:26906134

    Ocular hypertension is popular among people, with a prevalence of 3% to 10% in those older than 40 years old. Without proper intervention, over 10% of the patients with ocular hypertension would develop glaucoma in the following 5 to 10 years. Glaucoma has become one of the leading causes of blindness all over the world, which makes it essential for us to pay enough attention to the prevention and treatment of ocular hypertension. However, it is not cost-effective to treat all the patients with ocular hypertension. Certain side effects may also be caused with long-term medical treatment. Therefore, it is of great importance for ophthalmologists to identify the right time and use appropriate therapeutic methods. To introduce the knowledge of ocular hypertension, the definition, epidemiology, diagnosis, risk factors and treatment of ocular hypertension are reviewed in this article.

    The ocular surface is continuously exposed to the environment and, therefore, it is surprising that it harbors only few commensals with low degree of diversity. This unique aspect of the ocular surface physiology prompts the question whether there are core ocular commensal communities and how they affect ocular immunity. The purpose of this review is to provide an overview of what is known about the ocular surface commensals in health and disease and what we would like to learn in the near future. In addition, we discuss how microbiota at sites other than the eye may influence ocular immune responses. The information discussed in the review has been gathered using PubMed searches for literature published from January 1982 to December 2015.

    Abstract Cardiac sarcoidosis (CS) is a life-threatening and underdiagnosed manifestation of the disease, which requires a complicated and expensive diagnostic pathway. There is a need for simple tool for practitioners to determine the risk of CS without access to specialized equipment. The aim of study was to determine the prevalence of CS in a group of patients diagnosed with or followed up because of sarcoidosis. A secondary objective was the search for factors associated with heart involvement. We performed a prospective case–control study (screening analysis) in consecutive sarcoidosis patients collected from October 2012 to September 2015. Cardiac magnetic resonance (CMR) imaging was performed to confirm or exclude cardiac involvement in all patients. The study was conducted in a hospital-based referral center for patients with sarcoidosis and other interstitial lung diseases. Analysis was performed in a group of 201 patients (all white) with biopsy-proven sarcoidosis, mean age 41.4 ± 10.2, 121 of them (60.2%) males. Four patients with previously recognized cardiac diseases, which make CMR imaging for CS inconclusive, were not included. Cardiac involvement was detected by CMR in 49 patients (24.4%). Factors associated with an increased risk of CS (univariate analyses) included male sex (odds ratio [OR]: 2.5; 1.21–5.16, P = 0.01), cardiac-related symptoms (OR: 3.53; 1.81–6.89, P = 0.0002), extrathoracic sarcoidosis (OR: 3.48; 1.77–6.84, P = 0.0003), elevated serum NT-proBNP (OR: 3.82; 1.55–9.42, P = 0.004), any electrocardiography abnormality (OR: 5.38; 2.48–11.67, P = 0.0001), and contemporary radiological progression sarcoidosis in the lungs (OR: 2.98; 1.52–5.84, P = 0.001). Abnormalities in echocardiography and Holter ECG were also risk factors, but not significant in multivariate analyses. A CS Risk Index was developed using a multivariate model to predict CS, achieving an accuracy of 82%, sensitivity of 50

    Sarcoidosis is a multisystem disease with an unpredictable and sometimes fatal course while the underlying pathomechanism is still unclear. Reasons of the increasing hospitalization rate and mortality in the United States remain in dispute but incriminated are a number of distinct comorbidities and risk factors as well as the application of more aggressive therapeutic agents. Studies reflecting the recent development in central Europe are lacking. Our aim was to investigate the recent mortality and hospitalization rates as well as the underlying comorbidities of hospitalized sarcoidosis patients in Switzerland. In this longitudinal, nested case-control study, a nation-wide database provided by the Swiss Federal Office for Statistics enclosing every hospital entry covering the years 2002–2012 (n = 15,627,573) was analyzed. There were 8,385 cases with a diagnosis of sarcoidosis representing 0.054% (8,385 / 15,627,573) of all hospitalizations in Switzerland. These cases were compared with age- and sex-matched controls without the diagnosis of sarcoidosis. Hospitalization and mortality rates in Switzerland remained stable over the observed time period. Comorbidity analysis revealed that sarcoidosis patients had significantly higher medication-related comorbidities compared to matched controls, probably due to systemic corticosteroids and immunosuppressive therapy. Sarcoidosis patients were also more frequently re-hospitalized (median annual hospitalization rate 0.28 [IQR 0.15-0.65] vs. 0.19 [IQR 0.13-0.36] per year; p < 0.001), had a longer hospital stay (6 [IQR 2-13] vs. 4 [IQR 1-8] days; p < 0.001), had more comorbidities (4 [IQR 2-7] vs. 2 [IQR 1-5]; p < 0.001), and had a significantly higher in-hospital mortality (2.6% [95% CI 2.3%-2.9%] vs. 1.8% [95% CI 1.5%-2.1%] (p < 0.001). A worse outcome was observed among sarcoidosis patients having co-occurrence of associated respiratory diseases. Moreover, age was an important risk factor for re-hospitalization. PMID

    Vitamin-D insufficiency and sarcoidosis are more common and severe in African Americans (AA) than Caucasians. In sarcoidosis, substrate-dependent extrarenal 1,25-dihydroxyvitamin-D (1,25-(OH)2D) production is thought to contribute to hypercalciuria and hypercalcemia, and vitamin-D repletion is often avoided. However, the anti-inflammatory properties of vitamin-D may also be beneficial. We prospectively examined serum vitamin-D levels, calcium balance, and the effects of vitamin-D repletion in 86 AA and Caucasian patients with biopsy-proven active sarcoidosis from the USA (US) and Italy (IT) in university-affiliated outpatient clinics. Clinical features, pulmonary function, and calciotropic hormones were measured. 16 patients with vitamin-D deficiency and normal serum ionized calcium (Ca(2+)) were treated with oral ergocalciferol (50,000 IU/week) for 12 weeks. Baseline mineral parameters were similar in US (93% AA) and IT (95% Caucasian) patients irrespective of glucocorticoid treatment. Pulmonary dysfunction was less pronounced in IT patients. Nephrolithiasis (in 11% US, 17% IT patients) was associated with higher urinary calcium excretion. Vitamin-D deficiency was not more prevalent in patients compared to the respective general populations. As serum 25-hydroxyvitamin-D (25-OHD) rose postrepletion, serum 1,25-(OH)2D, γ-globulins, and the previously elevated angiotensin converting enzyme (ACE) levels declined. Asymptomatic reversible increases in Ca(2+) or urinary calcium/creatinine (Ca/Cr) developed in three patients during repletion. In conclusion, Caucasian and AA patients show similar calcium and vitamin D profiles. The higher prevalence of hypercalciuria and nephrolithiasis in sarcoidosis is unrelated to endogenous vitamin-D levels. Vitamin-D repletion in sarcoidosis is generally safe, although calcium balance should be monitored. A hypothesis that 25-OHD repletion suppresses granulomatous immune activity is provided.

    A bone biopsy specimen in a long-term hemodialysis patient with sarcoidosis coexisting with severe hypoparathyroidism has demonstrated that a persistent near physiological level of 1,25-dihydroxyvitamin D3 contributes to the preservation of bone remodeling and has the potential to retard the development of vascular calcification and atherosclerosis. Sarcoidosis-related hypercalcemia and hypoparathyroidism, which is characterized by 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) overproduction, is rarely seen in hemodialysis patients. Herein, we describe a 60-year-old Japanese woman on hemodialysis for 35 years who presented with malaise and hypercalcemia. Severe hypoparathyroidism without parathyroidectomy and a preserved 1,25(OH)2D3 level were detected. Computed tomography showed bilateral axillary lymphadenopathy and minimal aortic and soft tissue calcification. The axillary node biopsy led to a definite diagnosis of sarcoidosis. A bone biopsy specimen obtained from the right iliac crest showed remodeling of normal lamellar bone with scalloped cement lines and clear double labeling by tetracycline on fluorescence microscopy. Histomorphometric analysis revealed that the bone formation rate was preserved (30.0 %/year), together with a decrease of osteoid volume (5.75 %) and fibrous volume (0 %), indicating that the patient did not have adynamic bone disease and only showed mild disease. This is the first documented case of sarcoidosis-related hypercalcemia associated with severe hypoparathyroidism in a long-term hemodialysis patient who underwent bone histomorphometry. Our findings suggest that, in hemodialysis patients with sarcoidosis coexisting with severe hypoparathyroidism, a persistent near physiological level of 1,25(OH)2D3 contributes to the preservation of bone remodeling and has the potential to retard the development of vascular calcification and atherosclerosis.

    Introduction. The association between the level of systemic inflammation and systemic hypertension (sHTN) among subjects with sarcoidosis has not been previously explored. Methods. A retrospective study was conducted to investigate the relation between the level of systemic inflammation in sarcoidosis, measured by various serum inflammatory markers, and sHTN. Results. Among a total of 108 cases with sarcoidosis (mean age: 53.4 years, 76.9% females), 55 (50.9%) had sHTN and 53 (49.1%) were normotensive. ESR was highly associated with sHTN. The patients with sHTN had higher mean ESR levels compared with normotensives (48.8 ± 35 versus 23.2 ± 27 mm/hr, resp.; P = 0.001). ROC curve analysis for ESR revealed an AUC value of 0.795 (95% CI: 0.692–0.897; P = 0.0001). With regard to CRP, there was a trend towards higher mean values in sHTN group (3.4 versus 1.7 mg/L; P = 0.067) and significantly higher prevalence of sHTN in the highest CRP quartile compared to the lowest one (69.6% versus 30%; OR 4.95; P = 0.017). ROC curve analysis for CRP revealed an AUC value of 0.644 (95% CI: 0.518–0.769; P = 0.03). On multivariate analysis, ESR and the CRP remained independent predictors for sHTN among subjects with sarcoidosis. Conclusion. Systemic inflammation is associated with the presence of sHTN in sarcoidosis. PMID:27433355

    Several clinical and experimental studies have demonstrated that ocular surface disease is common in glaucoma patients receiving chronic glaucoma drops, and that the preservatives in these drops play a major role in the occurrence of ocular surface disease. These ocular surface changes may induce both symptoms reported by the patients and anterior segment clinical signs, and should be systematically assessed by history and exam in all glaucoma patients. In these patients with ocular surface disease, reducing the amount of preservatives administered to the eye should be strived for, rather than adding additional eye drops to alleviate or mask the side effects of the glaucoma drops.

    The major challenge faced by today’s pharmacologist and formulation scientist is ocular drug delivery. Topical eye drop is the most convenient and patient compliant route of drug administration, especially for the treatment of anterior segment diseases. Delivery of drugs to the targeted ocular tissues is restricted by various precorneal, dynamic and static ocular barriers. Also, therapeutic drug levels are not maintained for longer duration in target tissues. In the past two decades, ocular drug delivery research acceleratedly advanced towards developing a novel, safe and patient compliant formulation and drug delivery devices/techniques, which may surpass these barriers and maintain drug levels in tissues. Anterior segment drug delivery advances are witnessed by modulation of conventional topical solutions with permeation and viscosity enhancers. Also, it includes development of conventional topical formulations such as suspensions, emulsions and ointments. Various nanoformulations have also been introduced for anterior segment ocular drug delivery. On the other hand, for posterior ocular delivery, research has been immensely focused towards development of drug releasing devices and nanoformulations for treating chronic vitreoretinal diseases. These novel devices and/or formulations may help to surpass ocular barriers and associated side effects with conventional topical drops. Also, these novel devices and/or formulations are easy to formulate, no/negligibly irritating, possess high precorneal residence time, sustain the drug release, and enhance ocular bioavailability of therapeutics. An update of current research advancement in ocular drug delivery necessitates and helps drug delivery scientists to modulate their think process and develop novel and safe drug delivery strategies. Current review intends to summarize the existing conventional formulations for ocular delivery and their advancements followed by current nanotechnology based formulation developments

    We investigated surface antigens and spontaneous cytokine production of T cells from bronchoalveolar lavage fluid (BALF) and aqueous humor (AH) from pulmonary sarcoidosis patients for a better understanding of the role of T cells in granuloma formation. The levels of CD3, CD11b, and CD28 antigen expression on freshly isolated T cells in the BALF of patients were significantly lower than those in peripheral blood lymphocytes (PBL) of either sarcoidosis patients or healthy donors (HD). In contrast, the levels of CD80 (B7/B7-1) and CD86 (B70/B7-2) antigen expression were significantly higher on these T cells and alveolar macrophages in the BALF of patients. Fifty-three T cell clones (TCC) established from the BALF and AH of the three sarcoidosis patients displayed primarily either CD4+ CD11b+ CD28+ or CD4+ CD11b- CD28- phenotypes. Most (61-90%) of these TCC spontaneously produced greater amounts of IL-1 alpha, IL-10, tumour necrosis factor (TNF), and granulocyte-macrophage colony-stimulating factor (GM-CSF) than did TCC from the PBL from sarcoidosis patients or HD (P < 0.05). Interferon-gamma (IFN-gamma), IL-6, and IL-2, but not IL-4, were also produced by 40-48% of these TCC. These results suggest that CD4+ T cells of the affected organs of sarcoidosis patients are activated and involved in the immunopathogenesis of sarcoidosis through production of various cytokines.

    The optically transparent nature of the human eye has motivated numerous Raman studies aimed at the non-invasive optical probing of ocular tissue components critical to healthy vision. Investigations include the qualitative and quantitative detection of tissue-specific molecular constituents, compositional changes occurring with development of ocular pathology, and the detection and tracking of ocular drugs and nutritional supplements. Motivated by a better understanding of the molecular mechanisms leading to cataract formation in the aging human lens, a great deal of work has centered on the Raman detection of proteins and water content in the lens. Several protein groups and the hydroxyl response are readily detectable. Changes of protein compositions can be studied in excised noncataractous tissue versus aged tissue preparations as well as in tissue samples with artificially induced cataracts. Most of these studies are carried out in vitro using suitable animal models and conventional Raman techniques. Tissue water content plays an important role in optimum light transmission of the outermost transparent ocular structure, the cornea. Using confocal Raman spectroscopy techniques, it has been possible to non-invasively measure the water to protein ratio as a measure of hydration status and to track drug-induced changes of the hydration levels in the rabbit cornea at various depths. The aqueous humor, normally supplying nutrients to cornea and lens, has an advantageous anterior location for Raman studies. Increasing efforts are pursued to non-invasively detect the presence of glucose and therapeutic concentrations of antibiotic drugs in this medium. In retinal tissue, Raman spectroscopy proves to be an important tool for research into the causes of macular degeneration, the leading cause of irreversible vision disorders and blindness in the elderly. It has been possible to detect the spectral features of advanced glycation and advanced lipooxydation end products in

Patients treated at the Institut Curie - Centre de Protonthérapie in Orsay, France, received radiation therapy to cure ocular and skull-base cancers. Sixty percent of the patients treated for choroidal melanomas using 73 MeV protons report anomalous phosphenes. Delivering a radiation dose on the retina only is not sufficient to trigger the light flash. The present study may be the first indication of phosphenes triggered by protons of few tens of MeV.

    Sarcoidosis is a multisystem granulomatous disease of unknown etiology that primarily affects the lungs. Our previous work indicates that activation of p38 plays a pivotal role in sarcoidosis inflammatory response. Therefore, we investigated the upstream kinase responsible for activation of p38 in sarcoidosis alveolar macrophages (AMs) and PBMCs. We identified that sustained p38 phosphorylation in sarcoidosis AMs and PBMCs is associated with active MAPK kinase 4 but not with MAPK kinase 3/6. Additionally, we found that sarcoidosis AMs exhibit a higher expression of IRAK1, IRAK-M, and receptor interacting protein 2 (Rip2). Surprisingly, ex vivo treatment of sarcoidosis AMs or PBMCs with IRAK1/4 inhibitor led to a significant increase in IL-1β mRNA expression both spontaneously and in response to TLR2 ligand. However, a combination of Rip2 and IRAK-1/4 inhibitors significantly decreased both IL-1β and IL-6 production in sarcoidosis PBMCs and moderately in AMs. Importantly, a combination of Rip2 and IRAK-1/4 inhibitors led to decreased IFN-γ and IL-6 and decreased percentage of activated CD4(+)CD25(+) cells in PBMCs. These data suggest that in sarcoidosis, both pathways, namely IRAK and Rip2, are deregulated. Targeted modulation of Rip2 and IRAK pathways may prove to be a novel treatment for sarcoidosis.

    The purpose of this review was to systematically analyze publications related to the role of meibomian gland disease in ocular surface inflammation, with special reference to meibomitis as an inflammatory form of meibomian gland dysfunction (MGD). Meibomian gland inflammation is often present with the ocular surface inflammation in conditions such as blepharokeratoconjunctivitis, ocular rosacea, and phlyctenular keratitis, but its contribution is often overlooked, especially in younger subjects. This can result in misdiagnosis, mistreatment, and, sometimes, severe visual impairment. We identified a related disease entity, seen predominantly in young patients, of ocular surface inflammation associated with meibomitis, which we termed meibomitis-related keratoconjunctivitis. Its specific clinical features are similar to those observed in the above-mentioned diseases, and the inflammatory form of MGD was found to be closely involved in the ocular surface inflammation seen in those four diseases, based on our statistical evaluation. The diagnosis and management of meibomitis, an inflammatory form of MGD, is vital for the successful treatment of the induced ocular surface inflammation. We propose that the ocular surface and the adnexal meibomian glands should be considered as one unit, i.e., the "meibomian gland and ocular surface" (MOS), when encountered in the clinical setting.

    Ocular adnexal lymphoma (OAL) is a relatively common lesion in the practice of ophthalmic oncology. Although OALs are usually primary tumors, secondary involvement of the ocular adnexae by systemic lymphoma is also possible. The clinical and radiological features of OAL are non-specific. Thorough morphological evaluation, aided by immunostaining, cytogenetic studies and molecular testing, are necessary for accurate diagnosis. PMID:26972223

    We investigated the associations between latitude and the incidence of two different types of ocular melanoma, external ocular melanoma (exposed to sunlight) and internal melanoma (not exposed to sunlight), separately. Using 1992-2002 data from the Surveillance, Epidemiology, and End Results (SEER) Program of National Cancer Institute, we identified 2142 ocular melanoma cases in non-Hispanic whites, and then regressed the incidences of various types of ocular melanomas with latitude. Our analysis indicated that the higher the latitude (away from the equator, the less sun exposure), the lower the risk of external ocular melanoma (eyelid and conjunctival melanomas) among non-Hispanic whites (P for trend = 0.018). The incidence increased 2.48 fold from 47-48 degrees to 20-22 degrees. This trend is very similar to that of skin melanoma. The incidence of internal ocular melanoma (uveal melanoma) increased significantly with increasing latitudes (the less sun exposure, P for trend < 0.0001), it increased 4.91 fold from 20-22 degrees to 47-48 degrees. The latitudinal patterns of ocular melanomas may reflect the dual effects of sunlight exposure, i.e. a mutagenic effect of direct solar radiation on external ocular melanomas and a protective effect for internal uveal melanoma, which is similar to the sun radiation protective effects for various internal malignant tumors that are not exposed to the sunlight.

    Background & objectives: Growing body of literature on sarcoidosis in India has led to an increased awareness of the disease. With the advent of better imaging tools hitherto under-recognized manifestations of sarcoidosis are likely to be better recognized. We sought to study the rare clinical and radiological manifestations (<5%) in patients with sarcoidosis. Methods: Retrospective review of records of 164 patients with histopathologically proven sarcoidosis seen over six years in a tertiary care centre in north India, was done. Results: Fifty four rare manifestations were observed in 164 patients. Acute presentation in the form of Lofgren syndrome was seen in eight (4.9%) and Heerfordt's syndrome in two (1.2%) patients. Musculoskeletal manifestations included chronic sarcoid arthritis in three (1.8%), deforming arthritis and bone erosion in one (0.6%) each. Rare initial presentation with dilated cardiomyopathy in one (0.6%), complete heart block in two (1.2%), bilateral sequential facial nerve palsy in two (1.2%), and pyrexia of unknown origin was seen in one (0.6%) patient. Other rare manifestations included chronic respiratory failure in one (0.6%), dysphagia in one (0.6%), sicca syndrome in five (3%), massive splenomegaly in one (0.6%), portal hypertension in two (1.2%), hypersplenism, gastric sarcoidosis, ninth and tenth cranial nerve palsies, moderate pericardial effusion and nephrocalcinosis in one (0.6%) each, and pulmonary artery hypertension in two (1.2%) patients. Rare radiological manifestations included moderate pleural effusion in two (1.2%), pleural thickening in five (3%), calcification of intrathoracic lymph nodes in four (2.4%), alveolar (nodular) sarcoidosis in three (1.8%), and myocardial uptake of 18F-fluorodeoxyglucose (F-18 FDG) in two (1.2%) patients. Fourteen patients had airways obstruction and behaved typically like seasonal bronchial asthma with excellent response to corticosteroids. Interpretation & conclusions: Increased awareness of

    Many factors, such as environmental, microbial and endogenous stress, antigen localization, can trigger the immunological events that affect the ending of the diverse spectrum of ocular disorders. Significant advances in understanding of immunological and molecular mechanisms have been researched to improve the diagnosis and therapy for patients with ocular inflammatory diseases. Some kinds of ocular diseases are inadequately responsive to current medications; therefore, immunotherapy may be a potential choice as an alternative or adjunctive treatment, even in the prophylactic setting. This article first provides an overview of the immunological and molecular mechanisms concerning several typical and common ocular diseases; second, the functions of immunological roles in some of systemic autoimmunity will be discussed; third, we will provide a summary of the mechanisms that dictate immune cell trafficking to ocular local microenvironment in response to inflammation.

    Purpose. To discuss an unusual presentation of ocular toxocariasis. Methods. Case report. Results. A 40-year-old woman presented with decreased vision in the left eye with a long history of recurrent red eye from uveitis. Eosinophilia and positive ELISA titers for Toxocara canis favored the diagnosis of ocular toxocariasis. Over 3 months, an anterior scleral mass had a rapid growth raising the possibility of medulloepithelioma, which rarely can mimic uveitic syndromes. Surgical plan changed from local excision to enucleation. Histopathology demonstrated a large homogeneous mass of chronic inflammatory cells with inflammation of the overlying thinned out sclera, medial rectus insertion, and limbal cornea. The triad of peripheral granuloma, eosinophilia, and positive blood serology established the diagnosis of ocular toxocariasis. Conclusions. Ocular toxocariasis can mimic ocular malignancy such as medulloepithelioma in adults and rarely presents as an anterior scleral mass. PMID:25371681

    We investigated the effects of refractive correction and refractive defocus on the assessment of sensory ocular dominance. In 25 healthy subjects (4 males and 21 females) aged between 20 and 31 years, a quantitative measurement of sensory ocular dominance was performed with refractive correction and the addition of a positive lens on the dominant eye. Sensory ocular dominance was measured with a chart using binocular rivalry targets. The reversal point changed after the addition of a +1.00 D lens on the dominant eye in all subjects. However, sighting ocular dominance and stereopsis did not change after the addition of a positive lens on the dominant eye ( P > 0:05, Wilcoxon test). These results suggest that refractive correction affects sensory ocular dominance, indicating the possible development of a new type of occlusion for amblyopia in the future.

    The ophthalmologic findings associated with frontonasal dysplasia have not been defined previously in a large series of untreated children. We reviewed the ophthalmic manifestations of a series of patients with frontonasal dysplasia who were seen as part of their craniofacial evaluation. All had undergone a complete ophthalmologic examination before any manipulation of either the orbits or the soft tissues of the orbital contents. From 1986 to 1991, 23 patients with frontonasal dysplasia were seen; ophthalmologic abnormalities were found in 20 (87 percent). Abnormalities included significant refractive errors, strabismus, nystagmus, and eyelid ptosis. Three patients had amblyopia, a treatable cause of visual loss, from strabismus or anisometropia. Ten eyes in seven patients (30 percent) had severe structural anomalies, such as optic nerve hypoplasia, optic nerve colobomas, microphthalmia, cataract, corneal dermoid, or inflammatory retinopathy, that resulted in an acuity of 20/100 or worse. The high incidence of ocular abnormalities indicates that early assessment by an ophthalmologist should be part of the initial evaluation of patients with frontonasal dysplasia to detect treatable visual or ocular problems.

    A detailed ophthalmic evaluation including slitlamp biomicroscopy, measurement of corneal sensitivity using Cochet and Bonnet aesthesiometer, Schirmer's test and Goldmann applanation tonometry was carried out in 89 patients of Hansen's disease attending the leprosy clinic with or without ocular symptoms and willing to undergo eye evaluation. Thirty-one patients had lepromatous leprosy (8 with erythema nodosum leprosum), 56 patients had borderline disease (13 with reversal reactions) and 2 had tuberculoid disease. In addition to the well documented changes of lagophthalmos (6.7%), uveitis (7.3%) and cataracts (19%), we noted prominent corneal nerves in 133 eyes (74.7%), beaded corneal nerves in 19 eyes (10.7%), corneal scarring in 10 eyes (5.6%), corneal hypoaesthesia in 51 eyes (28%) and dry eye in 18 eyes (13%). Beaded corneal nerves and/or stomal infiltrates occurred mainly in the lepromatous group (75%). Ocular hypotony (IOP less than 12 mm Hg) was not seen more frequently in Hansen's as compared to age and sex matched controls with refractive errors or cataracts (33.7%, vs. 37.8%, p = 0.33). Our study highlights the primary corneal involvement with corneal neuropathy as the predominant feature of Hansen's disease.

    The intensity of gallium-67 scintiscans, lymphocyte counts in bronchoalveolar lavage fluid, and pathologic changes were studied in 26 patients with untreated pulmonary sarcoidosis. Noncaseating granulomas were recognized with significantly greater frequency in stage 2 (80 percent; 8/10 cases) than in stage 1 (43 percent; 6/14 cases). Alveolitis showed little relation to the roentgenographic stage. There was a strong correlation between the intensity of gallium uptake in pulmonary parenchyma and the detection rate of granuloma; however, the detection rate of alveolitis was not statistically different from the intensity of gallium uptake. A highly significant correlation was revealed between the lymphocyte counts in bronchoalveolar lavage fluid and the intensity of alveolitis. These observations suggest that the gallium uptake reflects mainly the presence of granuloma, and the lymphocyte count in bronchoalveolar lavage fluid reflects the intensity of alveolitis in patients with pulmonary sarcoidosis.

    Sarcoidosis is a granulomatous disorder mostly could involve intrathoracic structures. The gastric involvement is rare and the symptoms may be non-specific. We herein report a case of a 56-year-old female patient who was admitted due to chest tightness and discomfort. Computed tomography (CT) of the thorax revealed bilaterally nodular lesions in the lower lobes of the lung and pleural effusion on the left side. Positron emission tomography/CT showed lung nodules and gastric involvement with mesenteric lymphadenomegalies with pathological uptake of 18F-fluoro-2-deoxy-d-glucose. Pathological examination of the lung biopsy taken by thoracotomy demonstrated non-caseating granulomas. The gastric biopsies taken by endoscopy also showed non-caseating granulomas consistent with a diagnosis of sarcoidosis. PMID:26487882

Procedures A 39-year-old male with uveitic glaucoma presented with decreased vision and throbbing pain in his right eye. His intraocular pressure was elevated, and his vision was reduced to hand motion. Due to persistently elevated intraocular pressure refractory to medical treatment, the patient underwent a glaucoma drainage device procedure. During the procedure, a yellow, nodular conjunctival growth was noted and biopsied. Results Histopathological examination revealed multiple nonnecrotizing granulomata, some of which contained polarizable material. Conclusions Biopsies of patients with sarcoidosis may contain polarizable material without evidence of foreign body inoculation. PMID:27239467

    A 79-year-old woman was admitted complaining of progressive weakness and numbness of the right hand. The patient was otherwise healthy. The patient's history was unremarkable. Clinical and electrophysiological examination revealed a compression of the ulnar nerve in the ulnar sulcus and in Guyon's canal. Ultrasound evaluation showed a suspicious tumour proximal to the elbow close to the ulnar nerve. The ulnar sulcus was then released and an epineural and perineural lesion 3–4 cm proximal to the sulcus was excised under microscope. The histopathology confirmed the lesion as non-caseating sarcoid granulomas. The patient showed no other signs of systemic sarcoidosis, as neuropathy was the only symptom and the condition improved postoperatively. Sensory deficits and paraesthesia resolved fully. The extension of the minor finger remained slightly inferior compared with the not affected side. Sarcoid neuropathy is a rare neurological complication of sarcoidosis and has to be included in differential diagnosis of nerve conduction impairments. PMID:23192580

    A 70-year-old woman was admitted to our hospital because of the right limb pain and gait disturbance. (67)Ga scintigraphy showed an increased uptake in the spinal cord, mediastinal lymph node and right tibialis anterior muscle. Based on the histopathological findings of epithelioid cell granuloma in endobronchial ultrasound-guided transbronchial needle aspiration of lymph node, she was diagnosed as having probable spinal cord/muscular sarcoidosis. After she was treated with oral prednisolone, her limb pain and gait disturbance improved. Furthermore, uptake in (67)Ga scintigraphy was reduced after the treatment. In conclusion, (67)Ga scintigraphy is useful not only for diagnosis, but also for estimating the efficiency of the treatment for sarcoidosis involving multiple organs such as the spinal cord and skeletal muscle.

    Twenty-eight patients with skin sarcoidosis were treated with thymalin, thymogen, levamisole, dimocifon, with due consideration for their immune status. Immunostimulating therapy has failed. Plaquenil, phthivazide and duplex therapy did not result in noticeable improvement either. An individual pattern of mononuclear phagocyte response to various immunoregulators was revealed. The highest sensitivity to human interferon, hydrocortisone, and prospidine was determined in vitro. The highest effect was achieved by a combination of corticosteroids with prospidine, though in 20 percent of cases the disease recurred within 2 years. Since these drugs are not harmless for the body, the major indications for their prescription to patients with skin sarcoidosis (provided there are no direct indications because of other conditions) are the process activity and dissemination, cosmetic defects because of the disease. In case of a local involvement and uneventful course of the process a follow-up is advisable.

    In order to clarify the significance of anginal pain and myocardial thallium-201 scan defects in cardiac sarcoidosis, the pharmacologic effect of dipyridamole on myocardial perfusion was assessed by planar thallium-201 myocardial scintigraphy in patients with sarcoidosis. Thallium-201 myocardial scintigraphy was performed at rest and after 0.56 mg/kg intravenous dipyridamole during four minutes in 16 patients with sarcoidosis. The myocardial scan (45-degree and 70-degree left anterior oblique, and anterior views) was divided into 15 segments. Results were evaluated by the number of segmental defects and with a global perfusion score (from 0 to 60) by a semi-quantitative index depending on the size and severity of myocardial thallium-201 defects. Thirteen of the 16 patients showed partial or total reversion of their thallium-201 defects on redistribution scanning either at rest or after dipyridamole. The mean (+/- SD) number of myocardial perfusion defects that were present in all the patients decreased from 5.31 +/- 1.78 at rest to 3.25 +/- 2.52 after redistribution (p less than 0.001) and to 2.19 +/- 2.10 after dipyridamole (p less than 0.001). The mean global perfusion score increased from 53.2 +/- 3.0 at rest to 56.2 +/- 2.9 after redistribution (p less than 0.001) and to 57.2 +/- 2.7 after dipyridamole (p less than 0.001). A significant correlation (r = 0.82, p less than 0.001) was found between the increase of global perfusion score on redistribution and after dipyridamole. The reversibility of myocardial scan defects is a common finding in sarcoidosis. It makes unlikely the role of scar fibrosis or extensive confluent granulomas as a mechanism for such defects. The effect of dipyridamole suggests the presence of reversible disorders lying at the coronary microvascular level.

    Sarcoidosis is characterised by non-caseating granulomas that secrete pro-inflammatory cytokines, including interleukin (IL)-12, IL-23, and tumour necrosis factor (TNF)-α. Ustekinumab and golimumab are monoclonal antibodies that specifically inhibit IL-12/IL-23 and TNF-α, respectively. Patients with chronic pulmonary sarcoidosis (lung group) and/or skin sarcoidosis (skin group) received either 180 mg ustekinumab at week 0 followed by 90 mg every 8 weeks, 200 mg golimumab at week 0 followed by 100 mg every 4 weeks, or placebo. Patients underwent corticosteroid tapering between weeks 16 and 28. The primary end-point was week 16 change in percentage predicted forced vital capacity (ΔFVC % pred) in the lung group. Major secondary end-points were: week 28 for ΔFVC % pred, 6-min walking distance, St George's Respiratory Questionnaire (lung group), and Skin Physician Global Assessment response (skin group). At week 16, no significant differences were observed in ΔFVC % pred with ustekinumab (-0.15, p = 0.13) or golimumab (1.15, p = 0.54) compared with placebo (2.02). At week 28, there were no significant improvements in the major secondary end-points, although a nonsignificant numerically greater Skin Physician Global Assessment response was observed following golimumab treatment (53%) when compared with the placebo (30%). Serious adverse events were similar in all treatment groups. Although treatment was well tolerated, neither ustekinumab nor golimumab demonstrated efficacy in pulmonary sarcoidosis. However, trends towards improvement were observed with golimumab in some dermatological end-points.

    We report on a 72-year-old male patient who developed sarcoidosis of the mediastinal lymph nodes, the liver, and the prostate 11 years ago. Seven years later, he underwent transurethral resection of the prostate by laser due to hematuria. Pathology of the resected chips showed a ‘granulomatous prostatitis with epitheloid cells’. Malignancy was histologically excluded at that time. Four years later, he was diagnosed with an undifferentiated prostate carcinoma, with a Gleason score of 5 + 4 = 9. After initiation of antihormonal therapy, he underwent radical prostatectomy and pelvic lymphadenectomy, which revealed a pT3b pN1 carcinoma with infiltrated resection margins. Three months later, the prostate-specific antigen level was 1.4 ng/ml, and a local recurrence was suspected by ultrasound; consequently, a 68Ga-prostate-specific membrane antigen (PSMA) PET/CT was performed. This examination seemed to confirm the local recurrence, a right pelvic lymph node metastasis, and a hepatic metastasis. However, ultrasound with contrast medium could not confirm the metastatic spread to the liver. In palliative intention, radiotherapy of the pelvis was done. After 50 Gy, the supposed recurrence had markedly shrunk, and an additional boost dose with 16.2 Gy was applied. Two years later, the patient is still free of disease. Due to this clinical development, we doubt the diagnosis of a fulminant progression of the prostate cancer as suspected by PSMA-PET/CT. Instead, we suspect a recurrence of the previously proven sarcoidosis leading to false-positive results. Our focus in this report is on the interaction between PSMA-PET/CT and sarcoidosis. Another report on a case of sarcoidosis of the spleen seems to confirm this possibility [Kobe et al: Clin Nucl Med 2015;40: 897–898]. PMID:27721768

    Sarcoidosis is a chronic systemic disease with a wide array of clinical findings. Given that the clinical symptoms are not pathognomonic, chest radiographs have become essential to the initial diagnosis and choice of treatment modality. Diagnosis hinges on ruling out alternative diagnoses; sometimes, advanced radiologic techniques and histopathology are required. On this occasion, we present a case of a patient with generalized symptoms, no significant chest radiograph findings and lymphadenopathy where advanced imaging and pathology assisted in the diagnosis.

    Sarcoidosis is a granulomatous disease with an increased accumulation of T cells in lungs as a result of on-site proliferation and chemotaxis induced by chemokines. It has already been demonstrated that CCL3-5 levels were increased in BAL fluid of sarcoidosis patients. To analyze the expression of CCL3-5 chemokines by T-cell subtypes (CD4+, CD8+, Th1, Th2, Tc1 or Tc2) in the lungs of sarcoidosis patients, fifteen untreated sarcoidosis patients and eighteen control subjects were enrolled in this study. CD4+ and CD8+ cells were isolated from BAL fluid by positive magnetic selection. The expression of CCL3-5 and other cytokines in CD4+ and CD8+ cells were measured by flow cytometry. The percentage of CD4+ or CD8+ cells expressing CCL4 were significantly higher in sarcoidosis patients (22.3% and 58.1%) compared to those seen in healthy subjects (11.1% and 16.5%, P = 0.04 and P = 0.02, respectively). In addition, the expression of CCL3, CCL4 and CCL5 was significantly elevated in CD8+ cells (8.9%, 58.1% and 2.1%) compared to CD4+ cells (2.1%, 22.3% and 0.7%; P = 0.04, P = 0.009 and P = 0.04, respectively), whereas CCL4 was expressed by significantly more Tc1 than Th1 cells in sarcoidosis patients (P = 0.006). Our study shows the possible role of CD8+ cells and CD4+ cells in recruiting T cells to the site of inflammation in sarcoidosis through the release of CCL4, either alone or together with Th1/Tc1-associated cytokines.

    The appearances of the lungs on radiographs and computed tomographic (CT) scans were correlated with degree of uptake on gallium scans and results of pulmonary function tests (PFTs) in 27 patients with sarcoidosis. CT scans were evaluated both qualitatively and quantitatively. Patients were divided into five categories on the basis of the pattern of abnormality at CT: 1 = normal (n = 4); 2 = segmental air-space disease (n = 4); 3 = spherical (alveolar) masslike opacities (n = 4); 4 = multiple, discrete, small nodules (n = 6); and 5 = distortion of parenchymal structures (fibrotic end-stage sarcoidosis) (n = 9). The percentage of the volume judged to be abnormal (CT grade) was correlated with PFT results for each CT and radiographic category. CT grades were also correlated with gallium scanning results and percentage of lymphocytes recovered from bronchoalveolar lavage (BAL). Patients in CT categories 1 and 2 had normal lung function, those in category 3 had mild functional impairment, and those in categories 4 and 5 showed moderate to severe dysfunction. The overall CT grade correlated well with PFT results expressed as a percentage of the predicted value. In five patients, CT scans showed extensive parenchymal disease not seen on radiographs. CT grades did not correlate with the results of gallium scanning or BAL lymphocytes. The authors conclude that patterns of parenchymal sarcoidosis seen at CT correlate with the PFT results and can be used to indicate respiratory impairment.

    Gallium 67 citrate scans and serum angiotension converting enzyme (ACE) levels were obtained in 54 patients with sarcoidosis and analyzed in relation to clinical manifestation. /sup 67/Ga scans were abnormal in 97% of patients with clinically active disease (n = 30) and in 71% of patients with inactive disease (n = 24). Serum ACE levels were abnormally high (2 standard deviations above the control mean) in 73% of patients with clinically active disease and in 54% of patients with inactive disease. Serum ACE levels correlated significantly with /sup 67/Ga uptake score (r = .436; p < .005). The frequency of abnormal /sup 67/Ga scans and elevated serum ACE levels suggests that inflammatory activity with little or no clinical expression is common in sarcoidosis. Abnormal /sup 67/Ga scans were highly sensitive (97%) but had poor specificity (29%) to clinical disease activity. The accuracy of negative prediction of clinical activity by normal scans (87%) was better than the accuracy of positive prediction of clinical activity by abnormal scans (63%). /sup 67/Ga scans can be used to support the clinical identification of inactive sarcoidosis.

    Bronchoalveolar lavage was carried out in 36 subjects with sarcoidosis and 20 control subjects undergoing bronchoscopy for routine diagnostic purposes. The proportion of mast cells in the lavage fluid of subjects with sarcoidosis (mean (SE) 0.84% 0.09%; p less than 0.01) when compared with that of controls (mean 0.32% (0.05%); p less than 0.01). This increase was greatest in subjects with positive gallium scans but was not correlated with the percentage recovery of lymphocytes or radiographic stage. Anti-IgE induced histamine release from the bronchoalveolar cells of 15 subjects with sarcoidosis was significantly increased at all effective doses of anti-IgE. This accentuation of histamine release was significantly greater in patients with positive gallium scans and correlated directly with the percentage recovery of lymphocytes (r = 0.7, p less than 0.005). The dose-response curve of anti-IgE induced histamine release from bronchoalveolar cells of subjects with more than 20% of lymphocytes in the lavage cell population was significantly greater than the dose-response curves of subjects with fewer than 20% of lymphocytes and of controls.

    Cardiac sarcoidosis (CS) affects less than 5% of patients with pulmonary or systemic sarcoidosis, but when present is often associated with a spectrum of clinically significant conduction abnormalities and arrhythmias. The cardinal manifestations of CS include conduction disturbances, arrhythmias, or congestive heart failure. Less commonly, there is concealed subclinical disease. The electrophysiologic evaluation for CS includes a history and physical exam, ECG, and echocardiogram for all sarcoidosis patients, along with MRI, PET/nuclear scans, and EPS for certain subsets of patients. Despite variable data to support their efficacy, glucocorticoids should still be considered in the treatment plan of CS. Antiarrhythmics in isolation are often ineffective in controlling ventricular arrhythmias. Cardiac pacemakers have provided important therapy for patients with conduction defects and implantable cardioverter defibrillator (ICD) therapy provides the strongest insurance to prevent fatal arrhythmias from CS. A recent consensus statement provides guidance for clinicians on the diagnosis and management of arrhythmias associated with CS including indications for ICDs. The use of pacemakers, ICD implantation and early implementation of corticosteroid therapy have led to an improvement in the overall prognosis and clinical outcomes of CS.

    By observing the real-time behavior of focal liver lesions at three vascular phases (arterial, portal-venous, and late), contrast-enhanced ultrasound (CEUS) has been successfully applied to differentiate benign from malignant hepatic nodules. In recent years, numerous studies highlighted the usefulness of CEUS also for other applications such as abdominal trauma, renal, pancreatic, thyroid, and inflammatory bowel diseases, supporting its role even in differentiating benign from malignant splenic nodules. Therefore, the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) recently updated the guidelines for the use of ultrasound contrast agents in clinical practice, pointing out the indication to characterize splenic parenchymal inhomogeneity or suspected lesions found on conventional ultrasound (BUS). We describe the case of a patient with a history of colon cancer and finding, at BUS and CEUS, of hypoechoic lesions with a highly suggestive pattern for metastases, subsequently histologically proved to be splenic localizations of a benign and multisystemic granulomatous disease such as sarcoidosis. We therefore reviewed the current literature focusing on the role of CEUS in differentiating benign from malignant splenic lesions, emphasizing on the lack of data and numerical shortage of sarcoidosis derived-lesions in the available studies. We conclude that sarcoidosis remains a diagnosis of exclusion and new studies are needed before defining precise indications of CEUS in these patients.

    Chronic beryllium disease (CBD) is clinically similar to other granulomatous diseases such as sarcoidosis. It is often misdiagnosed if a thorough occupational history is not taken. When appropriate, a beryllium lymphocyte proliferation tests (BeLPT) need to be performed. We aimed to search for CBD among currently diagnosed pulmonary sarcoidosis patients and to identify the occupations and exposures in Ontario leading to CBD. Questionnaire items included work history and details of possible exposure to beryllium. Participants who provided a history of previous work with metals underwent BeLPTs and an ELISPOT on the basis of having a higher pretest probability of CBD. Among 121 sarcoid patients enrolled, 87 (72%) reported no known previous metal dust or fume exposure, while 34 (28%) had metal exposure, including 17 (14%) with beryllium exposure at work or home. However, none of these 34 who underwent testing had positive test results. Self-reported exposure to beryllium or metals was relatively common in these patients with clinical sarcoidosis, but CBD was not confirmed using blood assays in this population.

    In this article, we present a rare case of calcified deep vein thrombosis in a 42-year-old female patient with frequent relapses of pulmonary sarcoidosis since 1995, for which she was on maintenance therapy with corticosteroids and with consequential secondary diabetes. Recent femoral vein thrombosis was diagnosed with color Doppler in 2012. At the same time, calcified occlusive thrombus in vena cava inferior from the level of renal vein to the confluence of hepatic veins was diagnosed on abdominal multi-slice computed tomography (MSCT). Digital subtraction venography (DSV) revealed a well-developed collateral circulation through the paravertebral veins, azygos and hemiazygos vein. There were no risk factors for thrombosis other than sarcoidosis and diabetes. Deep vein thrombosis is rarely described with sarcoidosis, but according to literature reports, it usually appears as a recurrence and simultaneously at multiple locations. According to the current knowledge, we cannot say for sure whether it is a disease with an increased risk of deep vein thrombosis or there is a combination of multiple risk factors present simultaneously.

    Sixty seven patients with biopsy proven pulmonary sarcoidosis were prospectively studied to determine whether single point bronchoalveolar lavage cell counts were a useful indicator of functional outcome and whether repeated lavage helped in management. The mean follow up period was 25 (range 13-37) months. No patient was having corticosteroid treatment at the time of initial bronchoalveolar lavage. "High intensity alveolitis" (lymphocyte count greater than or equal to 28%) was present at the initial lavage in 42 patients. These patients showed a significant improvement in their pulmonary function and chest radiographs over the follow up period whereas patients with "low intensity alveolitis" did not. Of the 42 patients with high intensity alveolitis, 31 had chronic sarcoidosis (duration over two years, mean 80 months). These patients showed a significant improvement in FVC but not in TLCO. Corticosteroids resulted in greater functional and radiological improvement in the patients with high intensity alveolitis than in those with low intensity alveolitis. Repeat bronchoalveolar lavage in 34 patients, mean 8.4 months after the original lavage, showed a weak inverse relation between a reduced lymphocyte count and change in forced vital capacity and isotope uptake on a gallium scan. These correlations were too weak to make repeated cell counts useful in management. Our results suggest that high intensity alveolitis may be a favourable prognostic factor for lung function in pulmonary sarcoidosis, even in patients with chronic disease, but that repeat lavage adds little to the management of the individual patient.

    The aim of the present study was to investigate to what extent interstitial lung disease (ILD) in common variable immunodeficiency disorder (CVID)-associated granulomatous disease (GD) is similar to pulmonary sarcoidosis 20 patients with CVID/GD were included in a retrospective study conducted by the Groupe Sarcoïdose Francophone. Medical records were centralised. Patients were compared with 60 controls with sarcoidosis. Clinical examination showed more frequent crackles in patients than controls (45% versus 1.7%, respectively; p<0.001). On thoracic computed tomography scans, nodules (often multiple and with smooth margins), air bronchograms and halo signs were more frequent in patients than controls (80% versus 42%, respectively; p=0.004) as well as bronchiectasis (65% versus 23%, respectively; p<0.001). The micronodule distribution was perilymphatic in 100% of controls and in 42% of patients (p<0.001). Bronchoalveolar lavage analysis showed lower T-cell CD4/CD8 ratios in patients than in controls (mean ± sd 1.6 ± 1.1 versus 5.3 ± 4, respectively; p<0.01). On pathological analysis, nodules and consolidations corresponded to granulomatous lesions with or without lymphocytic disorders in most cases. Mortality was higher in patients than controls (30% versus 0%, respectively) and resulted from common variable immunodeficiency complications. ILD in CVID/GD presents a specific clinical picture and evolution that are markedly different from those of sarcoidosis. PMID:22903958

    Serum angiotensin converting enzyme activity is increased in many patients with pulmonary sarcoidosis and has been proposed as a measure of disease activity. Assay of serum angiotensin converting enzyme, bronchoalveolar lavage, and gallium scans were performed in 27 patients with biopsy proved pulmonary sarcoidosis. There was a positive correlation between serum angiotensin converting enzyme activity and an index of pulmonary gallium uptake assessed by the National Institutes of Health method (r = 0.7, p less than 0.001). There was no significant relationship (r = 0.19) between serum angiotensin converting enzyme activity and bronchoalveolar lavage lymphocytes expressed as a proportion of cells recovered. Increase in the enzyme activity had a sensitivity of 50% as a means of detecting high intensity alveolitis but specificity was only 45%. There was no significant difference in mean angiotensin converting enzyme activity between the following groups: those with positive and those with negative gallium scans; those with bronchoalveolar lavage lymphocyte counts less than or equal to 28% and those with counts greater than 28%. Although there was a significant correlation between the enzyme activity and one component of the alveolitis of sarcoidosis, the data suggest that serum angiotensin converting enzyme activity alone is neither sensitive nor specific enough for high intensity alveolitis.

    CD14 expression on alveolar macrophages (AM) was studied in patients with sarcoidosis using immunocytochemistry and cytometric analysis. Compared with healthy control donors, patients had elevated percentages of CD14-positive AM (22 percent vs 34 percent), and the antigen density was threefold higher (92 vs 297 channels). Furthermore, soluble serum CD14 (ssCD14) was significantly elevated in patients with sarcoidosis with an average of 5.3 +/- 1.6 mg/L vs 3.2 +/- 0.7 mg/L in healthy control subjects. Follow-up of one patient, whose lung function test results improved during therapy with corticosteroids, revealed a concomitant decrease of CD14 staining on AM and of ssCD14. Statistical analysis revealed a negative correlation between CD14 expression on AM and PO2 at rest (p = 0.0005), and after labor (p = 0.02). Levels of ssCD14 gave a positive correlation to reduction of Dco (p = 0.006) and VC (p = 0.05). These data suggest that CD14 expression is related to severity of disease and that it may be useful for monitoring in sarcoidosis. PMID:7508361

    A subset of beryllium-exposed workers develop beryllium sensitisation (BeS) which precedes chronic beryllium disease (CBD). We conducted an in-depth analysis of differentially expressed candidate genes in CBD.We performed Affymetrix GeneChip 1.0 ST array analysis on peripheral blood mononuclear cells (PBMCs) from 10 CBD, 10 BeS and 10 beryllium-exposed, nondiseased controls stimulated with BeSO4 or medium. The differentially expressed genes were validated by high-throughput real-time PCR in this group and in an additional group of cases and nonexposed controls. The functional roles of the top candidate genes in CBD were assessed using a pharmacological inhibitor. CBD gene expression data were compared with whole blood and lung tissue in sarcoidosis from the Gene Expression Omnibus.We confirmed almost 450 genes that were significantly differentially expressed between CBD and controls. The top enrichment of genes was for JAK (Janus kinase)-STAT (signal transducer and activator of transcription) signalling. A JAK2 inhibitor significantly decreased tumour necrosis factor-α and interferon-γ production. Furthermore, we found 287 differentially expressed genes overlapped in CBD/sarcoidosis. The top shared pathways included cytokine-cytokine receptor interactions, and Toll-like receptor, chemokine and JAK-STAT signalling pathways.We show that PBMCs demonstrate differentially expressed gene profiles relevant to the immunnopathogenesis of CBD. CBD and sarcoidosis share similar differential expression of pathogenic genes and pathways. PMID:27103383

    Collagen was studied by biochemical and immunohistochemical means in 5 patients with granuloma annulare (GA) and 3 with cutaneous sarcoidosis (SA). The solubility of collagen from the lesional skin in acetic acid was higher than that of collagen from unaffected skin from both patients and control subjects. Collagen concentration in the skin lesions, measured in terms of hydroxyproline content, was reduced in 3 patients with granuloma annulare and one with sarcoidosis, but the ratio of type III/I collagen was unchanged vis-à-vis non-affected skin. The collagen concentration in non-affected skin of both GA and SA-patients was also lower than in controls. The most typical immunohistochemical finding was the association of type III procollagen and fibronectin with granulomas in the lesional skin of both GA and SA cases. The activity of prolyl hydroxylase, a key enzyme in collagen biosynthesis, was markedly increased in the lesional skin, indicating that collagen synthesis in vivo was also increased. Surprisingly, collagen synthesis was not increased in cell culture studies. This could be due to cell selection as observed previously in scleroderma. Another possibility could be that various mediators released in vivo from inflammatory cells activate fibroblasts. However, when cells are subcultivated, this effect is not maintained. In conclusion, marked changes in collagen could be observed in granuloma annulare and skin sarcoidosis, reflecting increased turnover of collagen in vivo.

    A devastating consequence of autoimmune-mediated, aqueous tear deficiency is pathological keratinization of the ocular surface. It is setoff by an aberrant immune response that promotes a program of altered mucosal epithelial cell differentiation. The management of keratinizing ocular surface disease is challenging. Topical therapies are largely inadequate for acute exacerbations, and progressive disease often requires systemic immunosuppression. A combination of translational and basic science research is necessary to understand the link between aberrant immunity and pathological keratinization. I review recent research and future directions aimed to develop targeted therapies that control or prevent ocular surface keratinization.

    The increasing understanding of immune mechanisms changed our perception of the ocular surface, which is now considered a compartment of the common mucosal immune system. It offered the possibility to alter the physiological immune response on the ocular surface and effectively combat inflammation, which impairs stability of the tear film and causes tear hyperosmolarity, causing symptoms of dry eye disease. The paper provides an overview of ocular surface anatomy and physiology, explains the underlying mechanisms of dry eye disease and discusses novel and promising treatment modalities, such as cyclosporine A, biological therapies using autologous serum and various growth factors as well as experimental treatment methods which are currently being investigated.

    Ocular inflammatory disorders disproportionately affect women, and the majority of affected women are of childbearing age. The role of sex or reproductive hormones has been proposed in many other inflammatory or autoimmune disorders, and findings from non-ocular autoimmune diseases suggest a complex interaction between sex hormones, genetic factors and the immune system. However, despite the age and sex bias, factors that influence this disparity are complicated and unclear.

    The definition of the term 'immune privilege' has evolved over the last century. Current usage refers to a state within a particular organ or tissue in which elements of normal immunity are absent. The fact that this deficiency is thought to be generally beneficial has compelled others to go a step further and venture that immune privilege acts to minimize expression of immunopathology. The purpose of this article is to review which parts of the eye hold immune privileged status, what mechanisms contribute to it, and what clinical benefits may have driven the development of these unique immune environments. The article ends with an examination of recent studies which have sought to use components of ocular immune privilege to prevent systemic autoimmune disease.

    The shape of the eye prostheses depends on the plastic surgery type. Standard prostheses with thin but not sharp edges are used to recreate the conjunctival cavity, prostheses with a deep retraction or flat ones are employed for a delayed introduction into the stump, prostheses with a 'swelling' at the upper edge are of use in surgery to correct the upper eyelid falling in, prostheses with a flattened lower edge and a 'shelf' at the upper edge are used to fortify the lower eyelid. Individual prostheses are recommended after plastic surgery. The prostheses should not prevent free closing and blinking of the eyelids, retaining the identical opening of the eyes. An inadequately chosen prosthesis brings to nothing the tremendous work made by the surgeon. Ocular prosthetics may be regarded as the final stage stabilizing the results of plastic surgery.

    Ocular melanoma is the most common adult primary intraocular tumour. Although <1% of patients have metastatic disease at the time of initial diagnosis, most will develop metastasis at varying lengths of time. Metastasis surveillance is therefore critical in the follow-up of patients with ocular melanoma. Liver is the most common site of metastasis and prognosis is based on the treatment of liver metastasis. Hence, imaging of liver metastasis is vital. MRI is the most specific modality for imaging liver metastasis and is at least as sensitive as CT. Extrahepatic metastasis such as retroperitoneal nodules and bone metastases are also better evaluated on MRI. Gadolinium-based contrast agents are extremely helpful for detecting liver lesions. In particular, newer hepatobiliary contrast agents which offer an additional hepatobiliary phase of excretion help in the detection of even tiny liver metastases. Diffusion-weighted imaging is helpful when an i.v. contrast cannot be administered. Treated lesions are also better evaluated with MRI. CT is useful for evaluating lung nodules, large liver metastasis or in patients in whom MRI is medically contraindicated. The disadvantage lies in its inability to detect small liver metastasis and the radiation dose involved. The lesions treated with iodized oil as part of chemoembolization procedures can be followed on CT. Ultrasound can be used only for detecting hepatic metastases. However, it is heavily operator dependent, technically challenging and time consuming especially in patients who are large. Extrahepatic metastasis cannot be seen on ultrasound. Its utility is primarily for the biopsy of liver lesions. Positron emission tomography (PET)-CT can detect lung nodules and large liver lesions but is insensitive to small liver lesions. Moreover, the high radiation dose is a major disadvantage. PMID:27168029

    The custom-made ocular prosthesis contributes to enhanced tissue health of the anophthalmic socket. For this purpose, an acrylic resin ocular prosthesis may be modified, by using an appropriate dental impression material and being adapted closely to the anophthalmic socket. The modeling impression material is subsequently replaced by acrylic resin. This article describes the application of a viscoelastic tissue conditioner material, as an impression medium for prosthetic modification of an ocular prosthesis. The tissue conditioner material exhibits favorable tissue compatibility, adhesion to acrylic resin, and detailed surface registration. These advantages facilitate the clinical procedure and evaluation of modifications made to the ocular prosthesis.

    Current concepts of the pathogenesis of sarcoidosis suggest that the alveolitis of this disorder is related to increased numbers of mononuclear phagocytes and activated T-lymphocytes within the lung. To determine if 67Ga scanning, a procedure commonly used in the evaluation of inflammation, would be useful in staging the alveolitis of sarcoidosis, we studied 41 patients with this disorder and correlated estimates of pulmonary 67Ga accumulation with clinical, roentgenographic, physiologic, and bronchoalveolar lavage studies in these patients. Although 65% of patients with sarcoidosis showed increased amounts of 67Ga accumulation in the lung compared with control subjects, only weak correlations (r less than +/- 0.42, all comparisons) were found between the degree of gallium uptake and the clinical, roentgenographic, or physiologic data. In contrast, there was a strong correlation of 67Ga uptake and the number of lymphocytes and T-lymphocytes recovered from the lungs of these patients by bronchoalveolar lavage (p less than 0.0001, r greater than or equal to 0.67, both comparisons). This data suggested that gallium uptake reflects the intensity of the T-lymphocytes mediated component of the alveolitis in sarcoidosis. Because 67Ga scans are noninvasive, simple to perform, and widely available, they should prove useful to stage the activity of sarcoidosis and to make decisions regarding therapy directed against the alveolitis of the disease.

    A novel technique for the study of human eye movements was used to investigate the frequency components of ocular drift and microtremor in both eyes simultaneously. The tangential components of horizontal eye accelerations were recorded in seven healthy subjects using light-weight accelerometers mounted on scleral contact lenses during smooth pursuit movements, vestibulo-ocular reflexes and eccentric gaze with and without fixation. Spectral peaks were observed at low (up to 25 Hz) and high (60-90 Hz) frequencies. A multivariate analysis based on partial coherence analysis was used to correct for head movement. After correction, the signals were found to be coherent between the eyes over both low- and high-frequency ranges, irrespective of task, convergence or fixation. It is concluded that the frequency content of ocular drift and microtremor reflects the patterning of low-level drives to the extra-ocular muscle motor units. PMID:10422719

    Diabetes mellitus (DM) is a metabolic disease defined by elevated blood glucose (BG). DM is a global epidemic and the prevalence is anticipated to continue to increase. The ocular complications of DM negatively impact the quality of life and carry an extremely high economic burden. While systemic control of BG can slow the ocular complications they cannot stop them, especially if clinical symptoms are already present. With the advances in biodegradable polymers, implantable ocular devices can slowly release medication to stop, and in some cases reverse, diabetic complications in the eye. In this review we discuss the ocular complications associated with DM, the treatments available with a focus on localized treatments, and what promising treatments are on the horizon. PMID:27119078

    The present paper describes a technique to quantify eye rotations about the visual axis (ocular torsion). Two digitized polar transformed images of the iris are displayed on a video monitor in order to facilitate a visual comparison and manual interaction. Emphasis is placed on error analysis and the method's simplicity when applied to static ocular torsion measurement. The implementation, applying averaging over ocular torsion determined in partitioned iris images, yields a theoretical resolution of 5' of arc. In a control experiment with an artificial eye, the accuracy showed to be better than 14' of arc. In practice, the measuring device was validated with the data from the literature by means of an experiment about ocular torsion in humans during tilt and hypergravity conditions (up to 3 g).

    Familial amyloid polyneuropathy (FAP) or transthyretin (TTR) amyloid polyneuropathy is a progressive sensorimotor and autonomic neuropathy of adult onset, which is transmitted as an autosomal dominant trait. In addition to neurologic symptoms, FAP may be associated with weight loss, cardiac and renal failure and ocular complications. FAP is a devastating disease, causing death within 10years after the first symptoms. The TTR Val30Met mutation is the most common of more than 100 amyloidogenic mutations identified worldwide. Liver transplantation (LT) is currently the only treatment for preventing synthesis of the amyloidogenic variants of TTR. LT can halt progression of the neuropathy in up to 70% of cases and doubles the overall median survival of young Val30Met patients. Oral administration of tafamidis, which prevents deposition of mutated TTR, is now available to delay neurologic complications in early stages of the disease. Ocular manifestations of FAP are frequent and mainly include keratoconjunctivitis sicca, secondary glaucoma, vitreous deposits and pupillary abnormalities. Retinal and choroidal vascular abnormalities are more rare. Since ocular TTR is synthesized, at least in part, in the retinal pigment epithelium, LT does not influence the course of ocular involvement. The effects of tafamidis on the latter are still unknown. Because LT and symptomatic treatments greatly improve life expectancy of patients with FAP, ocular involvement is becoming a more frequent challenge to address. This review summarizes the pathophysiology, clinical findings and possible treatments of ocular manifestations of FAP. PMID:24144522

    In multiple sclerosis (MS), nystagmus or internuclear ophthalmoplegia (INO) are the usual ocular motor dysfunctions. However, in patients with focal brainstem lesions, other rare manifestations may be observed, such as an isolated ocular motor nerve palsy or complex ocular motor disturbances. We report five MS patients with unusual ocular motor disturbances (bilateral third nerve palsy [n = 2], opsoclonus, Horner's syndrome and one-and-a-half syndrome). We discuss possible correlations between clinical disturbances and MRI abnormalities. Patients were seen in two MS centres. They had a confirmed diagnosis of MS and underwent a brain MRI and a complete neuro-ophthalmological work-up. In one case (opsoclonus), ocular motor manifestations were the first manifestation of MS. In the other four cases they occurred 3 months (Horner syndrome), 6 years and 12 years (bilateral third nerve palsy) and 2 years (one-and-a-half syndrome) after the disease onset, respectively. Four out of five patients were still in a relapsing-remitting form of MS. In the opsoclonus case, there was no evidence of a brainstem lesion. A gadolinium-enhanced lesion (2 cases) or a new T2-weighted lesion located in the brainstem correlated with the clinical presentation. All patients completely or partially recovered after corticosteroid infusions. Our study shows some rare or previously undescribed complex ocular motor symptoms in MS. PMID:16466746

    Giant cell myocarditis, but not cardiac sarcoidosis, is known to cause fulminant myocarditis resulting in severe heart failure. However, giant cell myocarditis and cardiac sarcoidosis are pathologically similar, and attempts at pathological differentiation between the two remain difficult. We are presenting a case of fulminant myocarditis that has pathological features suggestive of cardiac sarcoidosis, but clinically mimicking giant cell myocarditis. This patient was treated with cyclosporine and prednisone and recovered well. This case we believe challenges our current understanding of these intertwined conditions. By obtaining a sense of severity of cardiac involvement via delayed hyperenhancement of cardiac magnetic resonance imaging, we were more inclined to treat this patient as giant cell myocarditis with cyclosporine. This resulted in excellent improvement of patient's cardiac function as shown by delayed hyperenhancement images, early perfusion images, and SSFP videos. PMID:24826266

The PubMed database was searched using the keywords "axial length" (AL), "anterior chamber depth" (ACD), "corneal astigmatism," "corneal topography" and "trabeculectomy." The extracted studies were categorized based on the evaluated parameters and the biometry method (contact and non-contact). Comparable studies with respect to their sample size were combined for statistical analysis. Twenty-five studies including 690 individuals which met the inclusion criteria were selected. After trabeculectomy, a significant and persistent AL reduction, with a range of 0.1-0.19 and 0.1-0.9 mm measured with contact and non-contact methods, respectively, was observed. With respect to topographic changes, 0.38-1.4 diopters (D) with-the-rule (WTR) astigmatism was induced postoperatively. All studies revealed ACD reduction immediately after surgery, which gradually deepened and approximated its preoperative levels on day 14. ACD reduction was not significant after that period in the majority of cases. In conclusion, changes in ACD is of small amount and of short period, thus it can be ignored; however, reported changes in AL and keratometry are of sufficient magnitude and can affect the refractive prediction of combined cataract surgery and trabeculectomy.

    The overall goal was the development of a Cockpit Ocular Recording System (CORS). Four tasks were used: (1) the development of the system; (2) the experimentation and improvement of the system; (3) demonstrations of the working system; and (4) system documentation. Overall, the prototype represents a workable and flexibly designed CORS system. For the most part, the hardware use for the prototype system is off-the-shelf. All of the following software was developed specifically: (1) setup software that the user specifies the cockpit configuration and identifies possible areas in which the pilot will look; (2) sensing software which integrates the 60 Hz data from the oculometer and heat orientation sensing unit; (3) processing software which applies a spatiotemporal filter to the lookpoint data to determine fixation/dwell positions; (4) data recording output routines; and (5) playback software which allows the user to retrieve and analyze the data. Several experiments were performed to verify the system accuracy and quantify system deficiencies. These tests resulted in recommendations for any future system that might be constructed.

    Patents (pts) with pulmonary sarcoidosis will often have frequent gallium (Ga) studies to assess the response of alveolitis to corticosteroid therapy. Since many pts are young and the cumulative radiation burden significant the authors have evaluated the ability of computer based Ga lung imaging to reliably quantify Ga activity using a 0.5 mCi dose of Ga. Twelve pts with biopsy proven pulmonary sarcoidosis received 0.5 mCi of Ga-67 citrate intravenously and had a posterior view of the chest including a portion of the liver obtained at 24 hrs post injection. At 24 hrs the pts received an additional 2.5 mCi and were then imaged at 48 and 72 hrs. A gallium score (GS) was computer generated as follows: regions of interest (ROI's) were manually created for the lungs, liver and background. Following a 9 point spatial smooth and background subtraction, the images were scaled so that the liver activity was assigned an arbitrary value of 400 counts per pixel. The resulting average counts per pixel for the lungs were then summed for the GS. Using a paired T-test there was only a borderline significant difference (0.05sarcoidosis who commonly have serial studies.

    Digestive tract sarcoidosis (DTS) is rare and case-series are lacking. In this retrospective case-control study, we aimed to compare the characteristics, outcome, and treatment of patients with DTS, nondigestive tract sarcoidosis (NDTS), and Crohn disease.We included cases of confirmed sarcoidosis, symptomatic digestive tract involvement, and noncaseating granuloma in any digestive tract. Each case was compared with 2 controls with sarcoidoisis without digestive tract involvement and 4 with Crohn disease.We compared 25 cases of DTS to 50 controls with NDTS and 100 controls with Crohn disease. The major digestive clinical features were abdominal pain (56%), weight loss (52%), nausea/vomiting (48%), diarrhea (32%), and digestive bleeding (28%). On endoscopy of DTS, macroscopic lesions were observed in the esophagus (9%), stomach (78%), duodenum (9%), colon, (25%) and rectum (19%). As compared with NDTS, DTS was associated with weight loss (odds ratio [OR] 5.8; 95% confidence interval [CI] 1.44-23.3) and the absence of thoracic adenopathy (OR 5.0; 95% CI 1.03-25). As compared with Crohn disease, DTS was associated with Afro-Caribbean origin (OR 27; 95% CI 3.6-204) and the absence of ileum or colon macroscopic lesions (OR 62.5; 95% CI 10.3-500). On the last follow-up, patients with DTS showed no need for surgery (versus 31% for patients with Crohn disease; P = 0.0013), and clinical digestive remission was frequent (76% vs. 35% for patients with Crohn disease; P = 0.0002).The differential diagnosis with Crohn disease could be an issue with DTS. Nevertheless, the 2 diseases often have different clinical presentation and outcome. PMID:27442665

    Six patients with biopsy-proven renal sarcoidosis presented with renal failure of unknown origin; in none was the diagnosis of sarcoidosis initially considered. The serum creatinine concentration at the time of presentation ranged from 265 to 1380 μmol/l (3.0 to 15.6 mg/dl), with a mean of 787 μmol/l (8.9 mg/dl). Although only two patients were hypercalcemic at the time of presentation, the 24-hour urinary excretion of calcium was increased in three of the four patients in whom it was measured, and renal calculi were present in one case. Renal biopsy revealed interstitial nephritis and tubular atrophy in all cases, as well as nephrocalcinosis in three cases and noncaseating granulomas negative for acid-fast bacilli in four cases. In each patient steroid therapy led to a rapid improvement in renal function (mean post-treatment serum creatinine level 274 μmol/l [3.1 mg/dl]). The follow-up period ranged from 8 months to 8 years (mean 3.0 years). In three patients renal function remained stable with low-dose steroid therapy. In two cases recurrent hypercalcemia and deteriorating renal function accompanied steroid withdrawal but resolved with its reinstitution. In one additional case reversible deterioration in renal function accompanied tapering of the steroid dose; however, there was no hypercalcemia. This report emphasizes the importance of considering sarcoidosis in the differential diagnosis of acute renal failure of unknown origin. Long-term follow-up of such patients is essential, as relapse is common. ImagesFIG. 1FIG. 2FIG. 3 PMID:519562

    Cardiopulmonary exercise testing (CPET) plays an important role in the assessment of functional capacity in patients with interstitial lung disease. The aim of this study was to identify CPET measures that might be helpful in predicting the vital capacity and diffusion capacity outcomes of patients with thoracic sarcoidosis. A longitudinal study was conducted on 42 nonsmoking patients with thoracic sarcoidosis (median age = 46.5 years, 22 females). At the first evaluation, spirometry, the measurement of single-breath carbon monoxide diffusing capacity (DLCOsb) and CPET were performed. Five years later, the patients underwent a second evaluation consisting of spirometry and DLCOsb measurement. After 5 years, forced vital capacity (FVC)% and DLCOsb% had decreased significantly [95.5 (82-105) vs 87.5 (58-103) and 93.5 (79-103) vs 84.5 (44-102), respectively; P < 0.0001 for both]. In CPET, the peak oxygen uptake, maximum respiratory rate, breathing reserve, alveolar-arterial oxygen pressure gradient at peak exercise (P(A-a)O2), and Δ SpO2 values showed a strong correlation with the relative differences for FVC% and DLCOsb% (P < 0.0001 for all). P(A-a)O2 ≥22 mmHg and breathing reserve ≤40% were identified as significant independent variables for the decline in pulmonary function. Patients with thoracic sarcoidosis showed a significant reduction in FVC% and DLCOsb% after 5 years of follow-up. These data show that the outcome measures of CPET are predictors of the decline of pulmonary function. PMID:22331135

    Ocular and adnexal congenital disorders are those that manifest at birth and could involve single or multiple tissues. Several abnormalities have been reported in literature affecting reptilian ocular and/or adnexal tissues. The objectives of this review are: (i) review those disorders previously reported in reptile literature; (ii) present new cases; (iii) provide a basic classification of them according to the moment of occurrence and (iv) indirectly, encourage the clinician dealing with these cases to go further in their diagnosis. The authors consider that categorizing ocular and adnexal congenital disorders could help the clinician to deal with them. The categorization of these disorders required an intense review of cases previously reported in literature and allows the authors suspect that some of them could not have been accurately diagnosed according to the definitions of the anomalies and/or not accurately described. The authors consider that ocular and adnexal congenital disorders could have been underestimated in reptiles and further studies could be helpful to promote the description of new disorders and to expand the knowledge about those previously reported. The review will first describe abnormalities reported during organogenesis (describing possible etiopathogenesis, cases reported, an approach to their diagnosis and recommended therapeutic options).Then a mention of the ocular disorders occurring after organogenesis is made. These disorders are divided when possible in those affecting all or most part of the globe and those affecting only specific tissues (surface ectoderm, neurocrest and mesenchyma and neuroectoderm).

However, there has been a significant increase in the number of reports on systemic drug-induced ocular complications. If such complications are left untreated, then it may cause permanent damage to vision. Hence, knowledge of most recent updates on ever-increasing reports of such toxicities has become imperative to develop better therapy while minimizing toxicities. Areas covered The article is mainly divided into anterior and posterior segment manifestations caused by systemically administered drugs. The anterior segment is further elaborated on corneal complications where as the posterior segment is focused on optic nerve, retinal and vitreous complications. Furthermore, this article includes recent updates on acute and chronic ocular predicaments, in addition to discussing various associated symptoms caused by drugs. Expert opinion Direct correlation of ocular toxicities due to systemic drug therapy is evident from current literature. Therefore, it is necessary to have detailed documentation of these complications to improve understanding and predict toxicities. We made an attempt to ensure that the reader is aware of the characteristic ocular complications, the potential for irreversible drug toxicity and indications for cessation. PMID:22803583

    Ocular ischemic syndrome, also known as hypoperfusion/ hypotensive retinopathy or as ischemic oculopathy is a rare ocular disease determined by chronic arterial hypoperfusion through central retinal artery, posterior and anterior ciliary arteries. It is bilateral in 20% of the cases. Most often it appears due to severe occlusion of the carotid arteries (ICA, MCA>ECA), described in 1963 by Kearns and Hollenhorst. Occasionally it can be determined by the obstruction of ophtalmic artery or some arterities (Takayasu, giant cell arteritis). The risk factors are: age between 50-80 years, males (M:F = 2:1), arterial hypertension, diabetes, coronary diseases (5% of the cases develop ocular ischemic syndrome), vascular stroke, hemodialysis. The case we present is of an 63 years old man known with primary arterial hypertension, hypercholesterolemia, diabetes type 2 non insulin dependent and diagnosticated with ischemic cerebral stroke and bilateral obstruction of internal carotid arteries in march 2010, who is presenting for visual impairment in both eyes. The imaging investigations show important carotid occlusion and at the ophthalmologic evaluation there are ocular hypertension and rubeosis iridis at the right eye, optic atrophy at both eyes (complete in the right eye and partial in the left eye), with superior altitudinal visual field defect in left eye. The following diagnosis was established: Chronic ocular ischemic syndrome in both eyes with Neovascular glaucoma at the right eye, Anterior ischemic optic neuropathy at the left eye and laser panphotocoagulation at the right eye was started.

    Objective To describe the ocular signs and symptoms of patients complaining of eye irritation due to volcanic fog (vog). Methods The study utilized a non-comparative, retrospective chart review of 30 patients who had a chief complaint of eye irritation, which the subjects attributed to vog. Ocular signs and symptoms are described and related to the ambient concentration of sulfur dioxide (SO2), particulate matter sized 2.5 microns (PM2.5), and vog visibility in O‘ahu during the period of the study. Results Ocular signs noted were conjunctival injection (100%), clear mucous discharge (100%), papillary reaction (100%), punctal edema (80%), eyelid swelling (73.3%) and chemosis (63.3%). Ocular symptoms were itchiness (100%), foreign body sensation (100%), tearing (96.6%) and burning sensation (90%). All patients had concurrent respiratory symptoms. During the period of study, the highest 24-hour average concentration of particulate matter sized 2.5 microns (PM2.5) was 49.04 µg/m3 and vog was visually present. Conclusions Patients complaining of eye irritation due to vog have observable ocular signs and symptoms. PMID:22187513

    Mycobacterial spindle cell pseudotumours (MSP) are benign lesions characterised by local proliferation of spindle-shaped histiocytes caused by mycobacterial infections. Cerebral MSP due to Mycobacterium avium intracellulare (MAI) infection is rare, and is often misdiagnosed clinically and radiologically as a brain tumour. We present a case with underlying sarcoidosis and known pulmonary MAI infection presenting with partial seizures and headaches. Imaging of the brain revealed a solitary extra axial tumour within the right temporal area. Biopsy of the tumour showed evidence of MPS due to MAI infection. Prolonged treatment with antituberculous therapy showed complete resolution of the cerebral lesion.

    A 53-year-old woman was referred for ventricular fibrillation with resuscitation. A CT-angiography showed signs of a right ventricular enlargement without obvious cause. A cardiac MRI demonstrated a dilated and hypokinetic right ventricle with extensive late gadolinium enhancement. Arrhythmogenic right ventricular dysplasia (ARVD) was suspected according to the "revised ARVD task force criteria". An endomyocardial biopsy was inconclusive. The patient developed purulent pericarditis after epicardial ablation therapy and died of toxic shock syndrome. The post-mortem pathologic examination demonstrated sarcoidosis involving the heart, lungs, and thyroid gland. PMID:25995699

    A 37-year-old man with a history of chronic skin sarcoidosis had the classic triad of lupus pernio. Each of the lesions (nose, ears, and hands) revealed avid radiogallium accumulation. In addition, both the panda sign and the lambda sign of hilar-mediastinal lymph node uptake of radiogallium were present, despite normal results of chest radiography. Several other lymph node chains were also involved. The case can serve as a baseline to determine if other instances of lupus pernio have such a wide systemic distribution of radiogallium uptake.

    We estimated the effectiveness and safety of methotrexate monotherapy of sarcoidosis in 63 patients refractory to the previous treatment. Methotrexate was given weekly at a dose of 5-20 mg. 54% of the patients reported improvement of their condition. Parameters of spirogram and the ray picture improved in 63.2 and 54% of the cases respectively. Methotrexate proved safe and had to be discontinued only in 12.6% of the patients. It is concluded that methotrexate can be used at least in half of the cases as a safe alternative to systemic steroid therapy.

    Ganoderma lucidum (reishi mushroom) has been used in traditional Chinese and Japanese medicine as a herbal remedy for over 2000 years. Studies have shown that G. lucidum has anti-allergic, anti-oxidant, anti-tumor, anti-viral, and anti-inflammatory properties. A review of the literature revealed that there were no studies examining the use of G. lucidum for the treatment of skin diseases. Here, we report the case of a 44-year-old male patient who used soap enriched with G. lucidum and goat's milk for 3 days in treating annular cutaneous sarcoidosis. The patient showed almost complete regression of the lesions.

    Objectives Pulmonary sarcoidosis is an immune-mediated disease, and some patients can be effectively treated with corticosteroids. However, nearly half of all sarcoidosis patients relapse after corticosteroid withdrawal. Different subsets of CD4+ helper T cells participate in the immunopathogenesis of sarcoidosis. Thus, the aims of our study were to investigate whether the circulating subsets of CD4+ helper T cells were associated with sarcoidosis relapse and with its remission after retreatment. Additionally, we identified a useful biomarker for predicting the relapse and remission of sarcoidosis patients. Methods Forty-two patients were enrolled in the present study who had previously been diagnosed with pulmonary sarcoidosis and treated with corticosteroids. The patients were allocated into either a stable group if they exhibited sustained remission (n = 22) or a relapse group if they experienced clinical or radiological recurrence after treatment withdrawal (n = 20). Peripheral blood cells were collected from these patients and analyzed to determine the frequencies of subsets of circulating CD4+ helper T cells by flow cytometry. The patients in the relapse group were retreated with corticosteroids and immunosuppressive agents and were then reevaluated to determine the frequencies of dynamic subsets of circulating CD4+ helper T cells after remission. Results The frequencies of circulating Tregs were significantly increased concomitant with a decrease in the circulating Th17 cell frequency in the relapsed patients compared with the stable patients. The Treg/Th17 ratio was negatively correlated with sarcoidosis activity and was sensitive to retreatment. In addition, the percentage of isolated CD45RO+Ki67+ Tregs was higher in the patients who were stable and in those who recovered after retreatment than in those who relapsed. Conclusions An imbalance between Tregs and Th17 cells is associated with pulmonary sarcoidosis relapse after corticosteroid withdrawal. The

    Purpose Del22q11.2, also known as DiGeorge syndrome, has a spectrum of ocular, facial and systemic features. Despite features of T cell dysfunction, infection and autoimmunity (including juvenile idiopathic arthritis), uveitis has not been described in patients with DiGeorge syndrome. Methods We describe a case of a 25-year-old male with bilateral granulomatous panuveitis who after initial investigation and treatment for an infectious cause was determined to have autoimmune-related uveitis with evidence on clinical, laboratory and imaging assessments suggestive of ocular sarcoidosis. Results The patient was found to have a normal T cell count and T cell proliferative response that was compared to a control patient, and phenotypes determined by flow cytometry were normal. However, the CD4/CD8 ratio in this patient was slightly lower than normal and the number of CD28 negative T cells, in both CD4 and CD8 populations, were significantly higher than a control. Conclusions The significance of these T cell abnormalities is unknown in the context of this patient’s uveitis but is suggestive of a role in autoimmunity, which is a known phenomenon in del22q11.2 syndrome, although autoimmune-related uveitis is not a previously described feature.

    The proficiency of nonophthalmologists with direct ophthalmoscopy is poor, which has prompted a search for alternative technologies to examine the ocular fundus. Although ocular fundus photography has existed for decades, its use has been traditionally restricted to ophthalmology clinical care settings and textbooks. Recent research has shown a role for nonmydriatic fundus photography in nonophthalmic settings, encouraging more widespread adoption of fundus photography technology. Recent studies have also affirmed the role of fundus photography as an adjunct or alternative to direct ophthalmoscopy in undergraduate medical education. In this review, the authors examine the use of ocular fundus photography as an educational tool and suggest future applications for this important technology. Novel applications of fundus photography as an educational tool have the potential to resurrect the dying art of funduscopy.

    The use of platelet-rich preparations has experienced a significant increase in recent years due to its role in tissue-repair and regeneration. The aim of this study is to examine the available evidence regarding the application of plasma rich in growth factors, and its variations, on the ocular surface. A review is also presented on the effects of platelet-derived growth factors, the implications of the preparation methods, and the existing literature on the safety and efficacy of these therapies in ocular surface diseases. Despite the widespread use of platelet preparations there is no consensus on the most appropriate preparation method, and growth factors concentration vary with different systems. These preparations have been used in the treatment of ocular surface diseases, such as dry eye or persistent epithelial defects, among others, with good safety and efficacy profiles, but further studies are needed to compare to the currently available alternatives.

    Lymphocytes from individuals with inactive macular disciform lesions of presumed ocular histoplasmosis challenged with three histoplasmin antigens incorporated tritiated thymidine at a significantly higher rate than histoplasmin-stimulated lymphocytes of matched control and peripheral scar groups. This finding is consistent with the etiologic association of the disciform ocular syndrome and previous systemic infection with Histoplasma capsulatum. The disciform group had a higher mean response than the other two groups to pokeweed mitogen but not to phytohemagglutinin and had higher mean counts per minute to the specific antigens Toxoplasma gondii, Blastomyces dermatitidis, Cryptococcus neoformans, Mycobacterium tuberculosis, M battery, and M gaus, but not to Candida albicans. These data would suggest that individuals with the disciform lesion of presumed ocular histoplasmosis have a hyperreactive cellular immune response; this response may play an important role in the development of the disciform.

    We report a case series of neuroretinitis in ocular bartonellosis and describe the serologic verification for Bartonella henselae. This is a retrospective interventional case series of four patients who presented in the ophthalmology clinic of Hospital Universiti Sains Malaysia from June 2012 to March 2013. All four patients had a history of contact with cats and had fever prior to ocular symptoms. Each patient presented with neuroretinitis characterized by optic disc swelling with macular star. Serology analysis showed strongly positive for B. henselae in all of the patients. All patients were treated with oral azithromycin (except case 4, who was treated with oral doxycycline), and two patients (case 1 and case 3) had poor vision at initial presentation that warranted the use of oral prednisolone. All patients showed a good visual outcome except case 3. Vision-threatening ocular manifestation of cat scratch disease can be improved with systemic antibiotics and steroids. PMID:25120352

    When an enucleation or exenteration procedure removes the entire orbital contents but not the eyelids, an abnormally large orbital socket is created that would require an equally sized volume enhancing, flush fitting ocular prosthesis. The solid acrylic prosthesis would rest on or in the lower fornix and owing to its weight, causes distortion of the lower eyelid and/or asymmetrical alignment of the entire palpebral fissure. The aim of this article was to describe a method of fabricating a pneumatic light weight custom ocular prosthesis using lost wax technique to overcome the deteriorating effects of conventional solid ocular prosthesis.

    Inflammation of the eye is often times seen in association with systemic inflammatory diseases. Understanding the various forms of ocular involvement in these conditions is important as untreated ophthalmic involvement can lead to severe vision loss. In addition to providing a basic framework for diagnosis and treatment, this review will highlight the ocular manifestations of the following systemic inflammatory conditions: rheumatoid arthritis, systemic lupus erythematosus, Wegener's granulomatosis, Sjögren's syndrome, polyarteritisnodosa, primary antiphospholipid syndrome, Behçet's syndrome, Kawasaki disease, Cogan's syndrome and relapsing polychondritis.

    Lacrimal dysfunction syndrome (LDS) and meibomian gland dysfunction (MGD) are common pathologies of the ocular surface both characterized by quantitative and/or qualitative tear film changings. They may result in symptoms of eye irritation, clinically apparent inflammation and ocular surface disease. Recent researches about the chronic inflammatory nature of dry eye, revealed the possibility to develop new treatments for LDS like new immunological drugs. MGD, alone or if it occurs contemporary to LDS, can be treated with a thermal pulsation system, a useful tool to alleviate symptoms.

    Laser hazards on the modern battlefield include numerous applications with the potential for eye damage from both pulsed and high luminance continuous energy laser devices. The multitude of laser devices deployed both by friendly and threat forces represent a significant hazard to vision, and consequently duty performance. Increased application of high luminance devices for tactical use may result in accidental exposure and temporary or persistent symptoms. These symptoms may be confounded by ongoing ocular retinal disorders. The management of these patients requires additional laser training to prevent injury as well as more experience and training for first responders in order to triage individuals with vision disturbances thought secondary to ocular laser exposure.

    Objective Instability of ocular alignment may cause surgeons to delay surgical correction of childhood esotropia. We investigated the stability of ocular alignment over 18 weeks in children with infantile esotropia (IET), acquired non-accommodative esotropia (ANAET), or acquired partially-accommodative esotropia (APAET). Design Prospective observational study Participants Two hundred thirty-three children aged 2 months to <5 years with IET, ANAET, or APAET of less than 6 months duration Methods Ocular alignment was measured at baseline and at six-week intervals for 18 weeks. Main Outcome Measure Using definitions derived from a nested test-retest study and computer simulation modeling, ocular alignment was classified as ‘unstable’ if there was a change of ≥ 15 prism diopters (PD) between any two of the four measurements, as ‘stable’ if all four measurements were within ≤ 5 PD of one another, or as ‘uncertain’ if neither criteria was met. Results Of those who completed all three follow-up visits within time windows for analysis, 27 (46%) of 59 subjects with IET had ocular alignment classified as unstable (95% confidence interval (CI) = 33 to 59%), 20% as stable (95% CI = 11 to 33%), and 34% as uncertain (95% CI = 22 to 47%). Thirteen (22%) of 60 subjects with ANAET had ocular alignment classified as unstable (95% confidence interval (CI) = 12 to 34%), 37% as stable (95% CI = 25 to 50%), and 42% as uncertain (95% CI = 29 to 55%). Six (15%) of 41 subjects with APAET had ocular alignment classified as unstable (95% CI = 6 to 29%), 39% as stable (95% CI = 24 to 56%), and 46% as uncertain (95% CI = 31 to 63%). For IET, subjects who were older at presentation were less likely to have unstable angles than subjects who were younger at presentation (risk ratio for unstable vs. stable per additional month of age = 0.85, 99% CI = 0.74 to 0.99). Conclusions Ocular alignment instability is common in children with IET, ANAET and APAET. The impact of this finding
