    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. Multi-disciplinary approaches are required to achieve the best treatment outcomes for both ocular and systemic manifestations. PMID:26593141

    Many studies include elevated activity of angiotensin-converting enzyme (ACE) in serum in sarcoidosis and in ocular sarcoidosis as well, but there are only a few analyzing ACE activities in aqueous humor. The aim of this study is to illuminate the diagnostic value of ACE in aqueous humor in patients with ocular sarcoidosis. We analyzed twenty patients with ocular sarcoidosis and 18 patients with nonocular involvement. All patients have biopsy-positive sarcoidosis of the lungs and/or mediastinal lymph nodes. Blood samples for ACE serum levels were obtained from all patients. Aqueous humor samples were taken by paracentesis with a 25-gauge needle in local anesthesia. With appropriate statistical tests, we compared ACE activity in serum and aqueous humor in patients with and without ocular sarcoidosis. The majority of our patients with ocular sarcoidosis were female (12/20), also in the group with systemic sarcoidosis and without ocular involvement (12/6). Mean age of the whole analyzed group of sarcoidosis patients was 45 ± 6 years. There is no statistically significant difference in ACE activity in serum between two groups of patients (with and without ocular sarcoidosis). There is statistically significant difference in ACE activity in aqueous humor among patients with ocular and nonocular sarcoidosis. ACE activity in aqueous humor is significantly higher in patients with ocular sarcoidosis. Increased ACE activity in aqueous humor can point to a diagnosis of ocular sarcoidosis, without the need for ocular biopsy.

    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 systemic granulomatous disease of unknown cause affecting young and middle-aged adults. Patients commonly present with bilateral hilar lymphadenopathy, pulmonary infiltrates, and ocular and skin lesions. The heart, liver,spleen, salivary glands, muscles,bones, kidneys, and central nervous system also may be involved. Diagnosis is based on clinicoradiologic findings plus histologic evidence of noncaseating epithelioid granulomas, and exclusion of other granulomatous diseases. Prognosis correlates with mode of onset, host characteristics, initial clinical course, and extent of disease. The optimal management of sarcoidosis has not been well defined. Although corticosteroids remain the mainstay of treatment, there is little evidence for the optimal initiation, dosage, or duration of therapy. Topical steroids maybe considered for treatment of anterior uveitis and skin lesions. Systemic steroids are indicated for treatment of cardiac, nervous system, severe ocular, and symptomatic or progressive pulmonary involvement. There is little evidence for the efficacy of inhaled steroids. Cytotoxic agents and immunomodulators usually are reserved for treatment of complex or refractory disease. Of these agents, methotrexate is used more frequently because of its safety profile and possible steroid-sparing effects. Antimalarial agents are used frequently for skin lesions, and they have limited success in the treatment of pulmonary disease. Lung and cardiac transplantation is reserved for end-stage disease. Monitoring for symptoms of drug toxicity is essential, and prevention of osteoporosis must be addressed in patients taking long-term oral corticosteroids. It is not known if current therapy alters disease progression.

    Full Text Available Abstract 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

    Sarcoidosis is a systemic disease of unknown cause that is characterised by the formation of immune granulomas in various organs, mainly the lungs and the lymphatic system. Studies show that sarcoidosis might be the result of an exaggerated granulomatous reaction after exposure to unidentified antigens in individuals who are genetically susceptible. Several new insights have been made, particularly with regards to the diagnosis and care of some important manifestations of sarcoidosis. The indications for endobronchial ultrasound in diagnosis and for PET in the assessment of inflammatory activity are now better specified. Recognition of unexplained persistent disabling symptoms, fatigue, small-fibre neurological impairment, cognitive failure, and changes to health state and quality of life, has improved. Mortality in patients with sarcoidosis is higher than that of the general population, mainly due to pulmonary fibrosis. Predicted advances for the future are finding the cause of sarcoidosis, and the elucidation of relevant biomarkers, reliable endpoints, and new efficient treatments, particularly in patients with refractory sarcoidosis, lung fibrosis, and those with persistent disabling symptoms.

    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.

      To describe the gross and histopathological ocular findings in a horse following suspected lightning injury.   The eyes of a 2-year-old thoroughbred gelding were clinically and histopathologically evaluated following a severe lightning storm following euthanasia because of visual impairment.   Severe corneal edema and hydrops were noted clinically oculus dexter. Indirect ophthalmoscopy revealed bilateral symmetrical raised hyporeflective peripapillary geographic lesions. Histopathologic evaluation revealed corneal edema in the right eye with normal corneal endothelium. Posterior segment evaluation revealed localized, pericentral choroidal lesions characterized by the presence of hemorrhage, early fibrosis, and minimal lymphoplasmacytic, neutrophilic, and histiocytic inflammation with spindle cell proliferation. The retinas overlying the choroidal lesions were necrotic and mostly absent. Peripheral to the focal lesion, the retina abruptly returned to normal architecture peripheral to a zone of apoptotic photoreceptors. Centrally, swollen axons extended into the optic disc.   There have been few descriptions of ocular lesions in animals following suspected lightning injury. We believe these findings to be unique because of the type of thermal injury that may be characteristic of lightening injury. We do not know whether these lesions would have progressed over time. © 2011 American College of Veterinary Ophthalmologists.

    To investigate whether lacrimal gland uptake on (67)Ga-gallium citrate scintigraphy correlates with histopathologic evidence of sarcoidosis. A retrospective, pilot study of 31 patients with suspected sarcoidosis who underwent gallium scintigraphy and lacrimal gland biopsy. Lacrimal gland gallium uptake was assessed by subjective visual scoring (SVS) and lacrimal uptake ratio (LUR). Eleven (36%) patients had lacrimal gland biopsies containing noncaseating granulomas. A statistically significant correlation was found between lacrimal gland gallium uptake and biopsy positivity using SVS (p = 0.03) or LUR (p = 0.01). Using SVS, biopsy positivity rate increased from 0 to 50% in patients with mild to intense uptake. Using LUR, biopsy positivity rate increased linearly as the ratio increased from 13% (LUR  8). Lacrimal biopsy positivity rate significantly correlated with gallium uptake on scintigraphy. Both SVS and LUR methods appear to correlate with histologic results and may potentially aid in patient selection for biopsy.

    Sarcoidosis is a multisystemic inflammatory disease that commonly affects the eye and less often the neuro-ophthalmic pathways. The manifestations can be quite variable but can have characteristic signs and clinical features. This review provides a comprehensive overview of the various ocular and neuro-ophthalmic manifestations of sarcoidosis, emerging diagnostic measures and approach to treatment. Particular focus is given to recent advances in diagnostic approach and available treatment options. Laboratory investigations, chest and nuclear medicine imaging remain important techniques for helping to diagnose sarcoidosis. Recent evidence suggests a role for aqueous humor analysis in the diagnosis of ocular sarcoidosis. Characteristic neuroimaging may help differentiate neurosarcoidosis from other causes. The role of blind conjunctival biopsy for suspected neurosarcoidosis is discussed. The emerging role and use of biologics is delineated for the treatment of both ocular and neuro-ophthalmic sarcoidosis. Sarcoidosis can affect any part of the visual system: the most common ocular manifestation is uveitis and the most common neuro-ophthalmic manifestation is optic neuropathy. Although diagnosis remains challenging, recent advancements in diagnosis are promising. Emerging biologics with particular efficacy for ocular and neuro-ophthalmic disease provide expanding treatment options for sight-threatening disease.

    High-mobility group box-1 (HMGB1) is a nonhistone DNA-binding nuclear protein released from necrotic cells, which is also secreted by activated leukocytes and acts as a primary proinflammatory cytokine. In this study, we compared vitreous HMGB1 levels in ocular sarcoidosis with those in noninflammatory vitreoretinal diseases and evaluated its association with Th cell-related and proinflammatory cytokines. The study group consisted of 24 patients with ocular sarcoidosis. The control group consisted of 27 patients with proliferative diabetic retinopathy (PDR) and 24 with idiopathic epiretinal membrane (ERM). Vitreous fluid samples were obtained at the beginning of vitrectomy. Vitreous levels of HMGB1 and IL-1β, IL-4, IL-6, IL-10, IL-17A, IL-17F, IL-21, IL-22, IL-23, IL-25, IL-31, IL-33, IFN-γ, soluble CD40 ligand (sCD40L), and TNFα were measured. High-mobility group box-1 was detected in the vitreous of 23 of 24 patients (95.8%) with ocular sarcoidosis. Mean vitreous level of HMGB1 was the highest in the sarcoidosis group, followed by the PDR and ERM groups, with significant differences between the three groups. In the sarcoidosis group, vitreous levels of IL-6, IL-10, IL-31, IFN-γ, sCD40L, and TNFα were significantly higher than those in the idiopathic ERM group, and IFN-γ and sCD40L were significantly higher than those in the PDR group. Vitreous HMGB-1 level correlated significantly with IL-10, IFN-γ, and sCD40L levels but not with IL-6, IL-17, IL-31, or TNFα levels. The vitreous level of HMGB1 is elevated in ocular sarcoidosis and is associated with vitreous levels of Th1- and regulatory T-related cytokines, but not with proinflammatory or Th17-related cytokines.

    To evaluate the diagnostic value of delayed contrast-enhanced computed tomography (DE-CT) for cardiac sarcoidosis (CS) in patients with or without implantable devices, including a quantitative comparison with late gadolinium enhancement cardiac magnetic resonance (LGE-CMR). Twenty-four patients (mean age, 64 ± 9 years; 17 women) with known or suspected CS underwent retrospective electrocardiogram-gated DE-CT at 80 kV with knowledge-based iterative model reconstruction. Fourteen patients without implantable devices also underwent LGE-CMR, while ten with pacemakers or implantable cardioverter-defibrillators did not. The presence of hyperenhanced myocardium was assessed visually and quantitatively using a 5-standard deviation threshold above the mean of remote myocardium. Inter-observer agreement for visual detection of hyperenhanced segments on DE-CT was excellent in patients with implantable devices and in those without (κ = 0.91 and κ = 0.94, respectively). Comparisons of the percent area of hyperenhanced myocardium between DE-CT and LGE-CMR on both per-patient and per-segment analyses showed good correlations (r = 0.96 and r = 0.83, respectively; p < 0.001). The sensitivity and specificity of DE-CT for the diagnosis of CS were 94% and 33%. The extent of hyperenhanced lesion with DE-CT showed good agreement with LGE-CMR results. DE-CT showed high sensitivity for detecting CS and may be useful particularly in patients with contraindications to CMR. (orig.)

    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 multisystem inflammatory disease defined histologically by the formation of noncaseating granulomas. The etiology of sarcoidosis remains unknown. Heart involvement in the course of sarcoidosis concerns about 5% of patients. The most common manifestation of cardiac sarcoidosis are conduction abnormalities, arrhythmias and heart failure. The diagnostic algorithm includes performing a clinical history, a 12-lead electrocardiogram (ECG) and an echocardiogram. If any of the initial screening investigations yields an abnormality, diagnostics should be continue using advanced imaging techniques: cardiovascular magnetic resonance (CMR) or fluorodeoxyglucose positron emission tomography (FDG-PET). Nowadays endomyocardial biopsy is not performed routinely.The clinical picture of cardiac sarcoidosis is highly variable. Screening for cardiac sarcoidosis should be performed in all patients diagnosed with extracardiac sarcoidosis. Cardiac sarcoidosis should also be suspected in young patients without a diagnosis of sarcoidosis who present with conduction abnormalities of unknown etiology, because cardiac sarcoidosis may be the first or the only manifestation of the disease. © 2016 MEDPRESS.

    Full Text Available Systemic imaging of patients with suspect ocular tuberculosis include chest X-rays and computed tomography (CT scans. Reports have suggested a role for 18 fluorodeoxyglucose-positron emission tomography/CT (FDG-PET/CT scans. We report on the clinical utility of 18 FDG PET/CT in two patients. Case 1: A 38-year-old female patient presented with recurrent anterior uveitis. A 18 FDG-PET scan revealed metabolically active supraclavicular and chest lymph nodes. An aspiration cytology of the cervical lymph node revealed caseating granulomas suggestive of tuberculosis. Case 2: A 58-year-old female patient presented with recurrent anterior uveitis. A 18 FDG-PET scan revealed metabolically active lymph nodes in the neck. A biopsy of the cervical lymph node revealed epithelioid granulomas suggestive of tuberculosis. Both patients were started on standard antitubercular therapy with a subsequent marked reduction of activity. PET/CT scans may suggest the sites of safe high-yield biopsies.

    Cryptococcus neoformans is an infrequent cause of septic arthritis. Cryptococcal infections have been linked to sarcoidosis because of both inherent immunologic consequences of the disease and its typical immune modulating treatments. Cryptococcal infections should be suspected in patients with underlying immune deficiencies, and a high degree of vigilance should be exercised to avoid misdiagnosis, dissemination of infection, and meningitis.

    Full Text Available During the last two decades many advances have been made in the field of sarcoidosis. The disease is now recognised as a multisystem disorder occurring in patients with a genetic predisposition and an exposure to yet unknown transmissible environmental agent/s. The diagnosis is based on a compatible clinical and/or radiological picture, histological evidence of non-caseating granuloma and exclusion of other diseases capable of producing a similar clinical or histological picture. Treatment primarily consists of administration of corticosteroids, although there are valuable alternative drugs. Treatment should be considered in symptomatic patients with evidence of radiologic or lung function deterioration. The patients with extra-pulmonary involvement particularly with ocular, myocardial, and neuro-sarcoidosis almost always need treatment. For asymptomatic pulmonary sarcoidosis patients no therapy is needed.

  7. Evidence for Mycobacteria in Sarcoidosis

    2011-01-01

    Despite its recognition as a distinct granulomatous disease for over a century, the etiology of sarcoidosis remains to be defined. Since the early 1900s, infectious agents have been suspected in causing sarcoidosis. For much of this time, mycobacteria were considered a likely culprit, yet until recently, the supporting evidence has been tenuous at best. In this review, we evaluate the reported association between mycobacteria and sarcoidosis. Historically, mycobacterial infection has been investigated using histologic stains, cultures of lesional tissue or blood, and identification of bacterial nucleic acids or bacterial antigens. More recently, advances in biochemical, molecular, and immunological methods have produced a more rigorous analysis of the antigenic drivers of sarcoidosis. The result of these efforts indicates that mycobacterial products likely play a role in at least a subset of sarcoidosis cases. This information, coupled with a better understanding of genetic susceptibility to this complex disease, has therapeutic implications. PMID:21659662

    Sarcoidosis is an idiopathic disease which presents in anatomic areas of concern to otorhinolaryngologists. It can cause dysfunction of both auditory and vestibular systems. In patients known previously to have sarcoidosis, this disease should be seriously considered. In patients presenting with otologic disorders and associated facial nerve paralysis or other neuropathies, uveitis, granulomatous meningitis or diabetes insipidus, sarcoidosis should be suspected. An examination of the eyes as well as a chest X-ray is imperative. Sudden and fluctuating neurosensory hearing loss has been reported. There is a great need for the study of temporal bones from sarcoidosis patients.

    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. Copyright © 2013 Elsevier Inc. All rights reserved.

    We report a case of optic disc granuloma due to sarcoidosis. A 64-year-old, caucasian female with a history of pulmonary sarcoidosis presented with a vision loss on her left eye. The ophthalmologic examination revealed a discrete optic disc infiltrate compatible with the diagnosis of optic disc granuloma. Fluorescein angiography showed diffusion and impregnation of the granuloma without vascularitis. The optical coherence tomography demonstrated a homogenous and isoreflective lesion at the optic disc. The patient recovered her visual acuity after systemic corticosteroid treatment. Isolated optic disc granuloma is a rare condition of ocular sarcoidosis. Copyright © 2016 Elsevier Masson SAS.

    The cutaneous signs of sarcoidosis are extremely polymorphous and may be classified under several different headings. Herein, we report the case of a 51-year-old female patient presenting bilateral livedo of the knees accompanied by systemic signs with polyarthralgia, impaired general state of health, weight loss, and a sensation of dyspnoea. Skin biopsy revealed giant-cell granuloma around the dermal vessels, with no caseous necrosis. Histopathological examination of the patient's blood vessels revealed no abnormalities. Laboratory tests showed high levels of angiotensin converting enzyme (1.5×ULN), bilateral mediastinal adenomegaly and incipient pulmonary fibrosis. Systemic sarcoidosis was diagnosed on the basis of the overall clinical and laboratory picture. The patient subsequently presented hepatic involvement and hypercalcaemia associated with the sarcoidosis; systemic corticosteroid therapy (prednisone) was initiated, with slow dose-reduction. The outcome was favourable with a return to normal laboratory values, regression of the adenomegaly and subsidence of the livedo. The literature contains reports of a number of cases of livedo heralding sarcoidosis. The majority of such cases involved young or middle-aged female patients of Asian origin presenting systemic sarcoidosis, with a high frequency of ocular and neural involvement. Livedo could be accounted for by the specific disposition of granulomas around the arterioles, resulting in disturbance of local blood flow, which was probably associated with the mechanical compression of vessels and with the micro-thrombi noted at histology. Livedo may be considered a clinical sign of cutaneous sarcoidosis. Laboratory tests to screen for sarcoidosis may be proposed in the exploration of atypical livedo.

    Tuberculosis and sarcoidosis share similar histopathological findings. An aetiological connection between these diseases has been discussed. We report a case of pulmonary sarcoidosis, which occurred shortly after an isoniazid (INH)-resistant spinal tuberculosis was diagnosed which was suspected to be a miliary tuberculosis. This report illustrates the need to sensitise clinicians to two possible important causes of lung parenchyma alterations under tuberculostatic therapy.

    Sarcoidosis is a granulomatous disease which can affect multiple organ systems. Clinical and radiologic manifestations depend on the organ system involved and the chronicity of disease. Nail involvement in sarcoidosis is rare, but is clinically relevant as it indicates chronic systemic disease. Nail abnormalities can be identified radiographically, and when seen in patients with known or suspected sarcoidosis, should prompt careful evaluation of the underlying bone for osseous involvement. We describe a case of sarcoidosis with radiographic findings in the nails and distal phalangeal tufts, which were indicative of nail and osseous sarcoid involvement and strongly supported the presence of chronic systemic disease. Although the nail findings resolved clinically and on radiographs after treatment, the osseous findings showed only minimal improvement. To our knowledge, the radiographic findings of nail sarcoidosis have not been previously addressed in the literature. (orig.)

    Chopra, Amit; Kalkanis, Alexandros; Judson, Marc A

    2016-11-01

    Numerous biomarkers have been evaluated for the diagnosis, assessment of disease activity, prognosis, and response to treatment in sarcoidosis. In this report, we discuss the clinical and research utility of several biomarkers used to evaluate sarcoidosis. Areas covered: The sarcoidosis biomarkers discussed include serologic tests, imaging studies, identification of inflammatory cells and genetic analyses. Literature was obtained from medical databases including PubMed and Web of Science. Expert commentary: Most of the biomarkers examined in sarcoidosis are not adequately specific or sensitive to be used in isolation to make clinical decisions. However, several sarcoidosis biomarkers have an important role in the clinical management of sarcoidosis when they are coupled with clinical data including the results of other biomarkers.

    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. PMID:20665396

    Cutaneous lesions of sarcoidosis present with various manifestations including specific and non-specific cutaneous lesions. Ichthyosiform sarcoidosis is a rare form of cutaneous sarcoidosis, presenting with asymptomatic, adherent, polygonal scales, mainly appearing on the lower limbs.  Ichthyosiform sarcoidosis has a predilection for dark-skinned races, and cases affecting Japanese patients have rarely been reported in English literature.  We herein describe three Japanese cases of ichthyosiform sarcoidosis on the lower limbs. All of the patients were female, with an age range of 57-69 years old.  Histologically, sarcoidal granulomas were located in the mid- to lower dermis.  All cases had scar sarcoidosis on the knees.  Furthermore, Case 1 presented with papular sarcoidosis on the back, and Case 3 presented with subcutaneous nodules on the buttock as well as erythema nodosum-like lesions on the lower legs.  All patients had lung sarcoidosis, but ocular sarcoidosis was seen in only Case 2. Case 3 showed Heerfordt syndrome with facial nerve paralysis. Histological features showed that the granular layers were scarcely detected in the overlying epidermis; however, filaggrin expression was not decreased.  Sarcoidal granulomas accumulated around the sweat glands in one case, whereas those features were not detected in the other two cases. In conclusion, ichthyosiform cutaneous sarcoidosis may be overlooked or misdiagnosed as xerotic dry skin which is frequently found in elderly people, and ichthyosiform cutaneous lesions may be more prevalent than previously estimated.

    2014-01-01

    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

    Opportunistic infections (OI) are uncommon in sarcoidosis (1 to 10%) and mostly occur in patients with previously diagnosed disease or can rarely be the presenting manifestation. The most common OIs are, in descending order: aspergillosis, cryptococcosis, and mycobacterial infections. Treatment with corticosteroids is the most frequent risk factor for OI occurrence during sarcoidosis but immunosuppressive drugs and therapy with anti-TNFα are also risk factors. Overall, clinical presentation, treatment, and outcome are identical to that occur in other conditions complicated with the occurrence of OIs. However, some atypical presentations of OIs can mimic sarcoidosis exacerbation and misdiagnosis may lead clinicians to increase immunosuppression, causing worsening of the OI. The meticulous collection of patient's history along with factors differentiating OI from sarcoidosis exacerbation is key factor to optimally manage these patients.

    Cardiac involvement in systemic sarcoidosis sometimes provokes life-threatening ventricular tachyarrhythmia. Steroid administration is one of the fundamental anti-arrhythmia therapies. For an indication of steroid therapy, a definitive diagnosis of sarcoidosis is required.1) However, cases that are clearly suspected of cardiac sarcoidosis based on their clinical courses sometimes do not meet the current diagnostic criteria and result in the loss of an appropriate opportunity to perform steroid therapy.Here we report a case that was diagnosed as sarcoidosis by incidental biopsy of an inguinal lymph node during cardiac resuscitation for cardiac tamponade.2) While the inguinal lymph node was not swollen on computed tomography, a specimen obtained from an incidental biopsy during the exposure of a femoral vessel for the establishment of extracorporeal cardio-pulmonary resuscitation showed a non-caseating granuloma.This findings suggest a non-swelling lymph node biopsy might be an alternative strategy for the diagnosis for sarcoidosis if other standard strategies do not result in a diagnosis of sarcoidosis.

    2015-10-01

    Full Text Available Sarcoidosis is a chronic, multisystemic disease commonly affecting the lungs and lymphatic system and is characterized by the formation of noncaseating granulomas. Although several reports are available on cases developing both sarcoidosis and cancer metachronously, cases of simultaneous diagnosis of these diseases have rarely been reported. A 67-year-old woman diagnosed with endometrial cancer had developed systemic lymph node swelling, including bilateral hilar, paraaortic, and a few pelvic lymph nodes, as observed on preoperative imaging. During surgery, frozen sections of a paraaortic lymph node were examined, revealing noncaseating granulomas compatible with sarcoidosis. Next, modified radical hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymphadenectomy were performed. Postoperative pathological analysis revealed endometrioid adenocarcinoma of the uterus, and no metastasis but noncaseating granulomas were detected in the resected lymph nodes. Postoperatively, we identified cutaneous sarcoidosis and uveitis in the presence of a tuberculin-negative test. On the basis of these findings, we diagnosed the patients with endometrial cancer complicated by sarcoidosis. She underwent adjuvant chemotherapy, and at the 1-year follow-up, the lymph node swelling due to sarcoidosis was stable, and no recurrence of the cancer was observed. This turned out to be a case of early endometrial cancer mimicking advanced cancer by sarcoidosis. Histological confirmation and additional examination for sarcoidosis are necessary in cancer patients suspected of sarcoidosis.

    2014-01-01

    Purpose of review None of the medications used in clinical practice to treat sarcoidosis have been approved by the regulatory authorities. Understanding how to use disease-modifying antisarcoid drugs, however, is essential for physicians treating patients with sarcoidosis. This review summarizes the recent studies of medications used for sarcoidosis with a focus on nonsteroidal therapies. Studies from 2006 to 2013 were considered for review to update clinicians on the most relevant literature published over the last few years. Recent findings Several recently published pieces of evidence have helped expand our ability to more appropriately sequence second-line and third-line therapies for sarcoidosis. For instance, methotrexate and azathioprine may be useful and well tolerated medications as second-line treatment. Mycophenolate mofetil might have a role in neurosarcoidosis. TNF-α blockers and other biologics seem to be well tolerated medications for the most severely affected patients. Summary Corticosteroids remain the first-line therapy for sarcoidosis as many patients never require treatment or only necessitate a short treatment duration. Second-line and third-line therapies described in this article should be used in patients with progressive or refractory disease or when life-threatening complications are evident at the time of presentation.

    Korsten, P; Chehab, G

    2017-06-01

    Musculoskeletal manifestations in the context of sarcoidosis are frequently observed. The rheumatologist regularly encounters this disease in clinical practice. In the present review, we aim to give a current overview of the manifestations and treatments relevant to the practicing rheumatologist. The most frequently encountered manifestation is Lofgren's syndrome, which is characterized by bilateral ankle periarthritis, bilateral hilar lymphadenopathy, and erythema nodosum and has an excellent prognosis. Chronic arthropathy most commonly manifests as oligoarthritis, which sometimes hampers its differentiation from spondylarthropathies, especially when sacroiliitis, enthesitis or dactylitis are simultaneously present. Isolated vertebral granulomas are rare and require infectious and malignant disorders to be excluded, since there are no specific imaging findings that are exclusively found in vertebral sarcoidosis. The presence of granulomas in skeletal muscle is common in muscle biopsies, whereas clinically overt myopathy is present in only around 1-2% of patients. Therapeutic responses vary among the different clinical phenotypes. Non-steroidal anti-inflammatory drugs and low to medium dose glucocorticoids are the first-line therapy for musculoskeletal manifestations and often lead to adequate disease control in acute sarcoidosis. When these are ineffective or not tolerated, steroid-sparing agents are increasingly used in chronic sarcoidosis. Evidence for all medications used in sarcoid-related arthritis is comparatively scant. When supplementing vitamin D, the possible development of hypercalcemia, even at standard doses, needs to be considered; the optimal therapeutic levels for the prevention of medication-induced osteoporosis in sarcoidosis have not been firmly established.

  12. Fatigue syndrome in sarcoidosis.

    Science.gov (United States)

    Górski, Witold; Piotrowski, Wojciech J

    2016-01-01

    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.

    Sarcoidosis is a systemic disease that may present as tattoo granulomas. A patient with systemic sarcoidosis who developed a granulomatous reaction within a tattoo is presented to stimulate interest in this unusual phenomenon. A patient with a 6-year history of pulmonary sarcoidosis developed sarcoidal granulomas restricted to one pigment of a tattoo. Previous reports of sarcoidal granulomas within tattoos are reviewed, and information about the pathogenesis of this process is explored. Sarcoid granulomas may develop in tattoos as an isolated local reaction or as the presenting sign of systemic sarcoidosis. The reaction itself may provide insight into further understanding the pathogenesis of sarcoidosis.

    Sulavik, S.B.; Palestro, C.J.; Spencer, R.P.; Swyer, A.J.; Goldsmith, S.J.; Tierstein, A.S. (Univ. of Connecticut Health Center, Farmington (USA))

    1990-12-01

    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.

    2017-03-01

    Sarcoidosis is a debilitating, inflammatory, multiorgan, granulomatous disease of unknown cause, commonly affecting the lung. In contrast to other chronic lung diseases such as interstitial pulmonary fibrosis or pulmonary arterial hypertension, there is so far no widely accepted or implemented animal model for this disease. This has hampered our insights into the etiology of sarcoidosis, the mechanisms of its pathogenesis, the identification of new biomarkers and diagnostic tools and, last not least, the development and implementation of novel treatment strategies. Over past years, however, a number of new animal models have been described that may provide useful tools to fill these critical knowledge gaps. In this review, we therefore outline the present status quo for animal models of sarcoidosis, comparing their pros and cons with respect to their ability to mimic the etiological, clinical and histological hallmarks of human disease and discuss their applicability for future research. Overall, the recent surge in animal models has markedly expanded our options for translational research; however, given the relative early stage of most animal models for sarcoidosis, appropriate replication of etiological and histological features of clinical disease, reproducibility and usefulness in terms of identification of new therapeutic targets and biomarkers, and testing of new treatments should be prioritized when considering the refinement of existing or the development of new models.

    2017-09-01

    Full Text Available Background Sarcoidosis is a chronic inflammatory disease with a myriad of clinical manifestations. Treatment involves immunosuppression with corticosteroids or steroid-sparing agents. A proportion of patients does not respond to or are intolerant to therapy. Targeted immunotherapy with biologic agents has emerged as a novel approach with plausible mechanistic reasons to warrant study. Aims The aim of this review was to evaluate the evidence for the efficacy of biological therapy in sarcoidosis. Methods We conducted a systematic literature review and meta-analysis of all published randomised-controlled trials (RCT evaluating biological therapy in sarcoidosis, using MEDLINE and Embase databases, through to September 2017. The search terms included sarcoidosis, infliximab, adalimumab, etanercept, golimumab, certolizumab, rituximab, abatacept, tocilizumab, anakinra, ustekinumab, secukinumab. Only articles reporting RCTs were selected. Improvements in respiratory disease were assessed by changes in forced vital capacity (FVC by weighted mean difference (WMD. There were insufficient data on outcome measures in other organ systems to comparatively assess efficacy. Results The search identified 2,324 studies of which only 5 provided relevant and original data. This comprised a total of 364 patients, evaluating pulmonary, cutaneous and ocular sarcoidosis. One study in pulmonary disease and one study in cutaneous disease demonstrated improvements in the primary outcome. In pulmonary disease, meta-analysis of the treatment effect of anti-TNF therapy versus placebo on FVC revealed a WMD of 1.69 per cent (95 per cent confidence interval, 1.44–1.94. Conclusion There are insufficient data to suggest the long-term efficacy of anti-TNFα inhibitors in the treatment of sarcoidosis. This may be due to heterogeneity, small sample sizes and the lack of consistent reporting of outcome measures.

  1. Immune aspects of sarcoidosis.

    OpenAIRE

    Poulter, L W

    1988-01-01

    Although the initiating factor(s) is unknown, it is now accepted that pulmonary sarcoidosis develops as a result of an over-stimulated local cellular immune response. Starting as a lymphocytic alveolitis, there is a progression to granuloma formation within the interstitium as stimulated T lymphocytes release mediators capable of attracting and activating monocytes to differentiate into macrophages and epithelioid cells. We are also aware that macrophage-like cells must act as antigen present...

    A 35-year-old man presented with a 3-year history of arthralgia and purple coloration of the skin of his fingers and feet. Hand and foot radiography showed cystic bone lesions on phalanges suggestive of sarcoidosis. Lab tests revealed increased liver enzymes. Liver MRI evidenced an enlarged liver and retroperitoneal lymphadenopathy. Histological analysis of the finger skin, lymph nodes and liver demonstrated the presence of granulomas, confirming the diagnosis of sarcoidosis. The patient started prednisolone with rapid improvement of the symptoms. Skin lesions are divided into two groups: specific for sarcoidosis (with granulomas, lupus pernio-like) and nonspecific (without granulomas, erythema nodosum-like). Specific cutaneous lesions usually cause no other symptoms beyond cosmetic changes. Lupus pernio stands out for having distinctive features but, to the best of our knowledge, the simultaneous involvement of both hands and feet has never been reported.

    Purpose of Review Chronic sarcoidosis is a complex disease with numerous comorbid conditions and can be fatal in some cases. Recognizing causes of morbidity and mortality is important to effectively select treatments, manage symptoms, and improve outcomes. The purpose of this review is to examine emerging knowledge on morbidity and mortality in sarcoidosis. Recent Findings Approximately one to five percent of patients with sarcoidosis die from complications of sarcoidosis. Recent population studies indicate that mortality may be increasing over the past decade. The reasons behind these trends are unclear, but could include increasing incidence, detection rates, severity of disease, or age of the population. Morbidity of sarcoidosis is reflected by a trend of increased hospitalizations over recent years and increased use of healthcare resources. Morbidity can be caused by organ damage from granulomatous inflammation, treatment complications, and psychosocial effects of the disease. Recent studies are focused on morbidity related to cardiopulmonary complications, bone health, and aging within the sarcoidosis population. Last, sarcoidosis is associated with autoimmune diseases, pulmonary embolism, and malignancy; however, the underlying mechanisms linking diseases continue to be debated. Summary Morbidity in sarcoidosis is significant and multifactorial. Mortality is infrequent, but may be increasing over the years. PMID:25029298

    Pulmonary hypertension (PH) is a severe complication of sarcoidosis, with an unknown prevalence. The aetiology is multifactorial, and the exact mechanism of PH in the individual patient is often difficult to establish.

    Ethnicity is strongly associated with variable clinical presentation in sarcoidosis but the association between ethnicity and clinical characteristics has not previously been described in patients of Polynesian ancestry, Maori and Pacific Islander (PI). The objective of this study was to describe the clinical characteristics of sarcoidosis in Maori and PI patients and determine if those were different to European patients. A retrospective review of the medical records of 406 patients (69 Maori/PI) attending a specialist interstitial lung disease (ILD) clinic. The population (207 females, mean age at presentation: 36) reflected the current New Zealand census data (2013) with only people of Indian ethnicity over-represented. Parenchymal lung involvement was uncommon in Maori and PI patients (21% Scadding stage 2, 2% stage 3), and no patient had extensive pulmonary fibrosis (stage 4). Computed tomography (CT) patterns of sarcoid parenchymal lung involvement were less commonly reported for Maori/PI. There were no differences in respect of baseline lung function or requirement for treatment. Ocular and skin involvement occurred more frequently in Maori and PI (P = 0.0045, P = 0.03), and erythema nodosum was more common in Caucasians (P = 0.0008). People of Polynesian ancestry appear to have less pulmonary and more extra-pulmonary manifestations of sarcoidosis. This adds to our knowledge that sarcoidosis heterogeneity is influenced by ethnicity. © 2016 Asian Pacific Society of Respirology.

    PURPOSE: Psoriasis is a chronic inflammatory disease characterized by a systemic immunological response which is mainly driven by activated T helper (Th) 1 and Th17 lymphocytes. Like psoriasis, sarcoidosis is a chronic inflammatory disorder with Th1/Th17-driven inflammation. Therefore, we...... investigated the risk of sarcoidosis in patients with psoriasis compared to the background population in a nationwide cohort. METHODS: The study included the entire Danish population aged ≥10 years followed from 1st January 1997 until diagnosis of sarcoidosis, death or 31st December 2011. Patients...... with a history of psoriasis and/or sarcoidosis at baseline were excluded. Information on comorbidity and concomitant medication was identified by individual-level linkage of administrative registers. Incidence rates of sarcoidosis were calculated and adjusted hazard ratios (HRs) were estimated by multivariable...

    Sarcoidosis is a systemic granulomatous inflammation of unknown etiology, and seems to involve the liver parenchyma in most cases. However, sarcoidosis-associated hepatocellular carcinoma is rare. We report here a case in which a hepatocellular carcinoma occurred within the liver, which was probably involved as a result of systemic sarcoidosis. A 57-year-old Japanese man had been followed up for 2 years because of diabetic nephropathy and sarcoidosis. On admission for pneumonia, imaging studies revealed an unexpected hepatic tumor. Histology revealed a hepatocellular carcinoma accompanied by T-lymphocytic infiltration and marked granulomatous inflammation, which was surrounding some tumor nodules. The background liver parenchyma exhibited a moderate degree of fibrosis with granulomatous inflammation. The patient had no other apparent liver disease such as viral hepatitis, steatohepatitis, or primary biliary cirrhosis. Therefore, in the present case, sarcoidosis may be considered the probable background etiology for hepatocarcinogenesis.

  9. Granuloma formation in pulmonary sarcoidosis

    2013-12-01

    Full Text Available 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 towards 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.

    Full Text Available 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.

  11. Acquired Functional Asplenia in Sarcoidosis

    Stone, Richard W.; McDaniel, Willie R.; Armstrong, Earl M.; Young, Roscoe C.; Higginbotham-Ford, Edith A.

    1985-01-01

    Sarcoidosis is a recently identified cause of functional asplenia that can be diagnosed by radionuclide imaging. A 31-year-old woman with a five-year history of histologically compatible sarcoidosis was found to have nonvisualization of the spleen on technetium 99m sulfur colloid (radiopharmaceutical) liver-spleen scan. This scintigraphic finding was accompanied by poikilocytosis and Howell-Jolly bodies in the peripheral blood smear. A subsequent gallium 67 citrate scan reflected an abnormal increase in concentration of activity in the spleen, suggesting an active inflammatory process. Based upon this constellation of findings, it was concluded that acquired functional asplenia is the result of reticuloendothelial cell replacement via infiltration of the spleen by epithelioid cell granulomas of active sarcoidosis. This case also illustrates the reversibility of functional asplenia of sarcoidosis following adrenocorticosteroid therapy. Functional asplenia in sarcoidosis is now found to have a recognizable radionuclide imaging pattern. ImagesFigure 1Figure 2Figure 3 PMID:3908697

    Full Text Available Here, we report a patient with sarcoidosis who developed edematous erythema and interstitial lung disease. At the initial visit, clinically amyopathic dermatomyositis (CADM with rapidly progressive interstitial lung disease (RP-ILD was suspected because he had progressive dyspnea but no muscle weakness. The presence of anti-CADM-140/MDA5 autoantibodies was immediately assessed to facilitate a precise diagnosis, with negative results. Thereafter, skin and transbronchial lung biopsies revealed noncaseating granuloma with Langhans giant cells in both specimens, leading to a diagnosis of sarcoidosis. In this case, clinical features of skin and lung were unable to distinguish DM (including CADM from sarcoidosis, but the lack of anti-CADM-140/MDA5 antibody was useful for differentiating CADM with RP-ILD mimicking sarcoidosis from bona fide sarcoidosis.

    Full Text Available Abstract Background Sarcoidosis is a chronic, systemic granulomatous disease of unknown etiology that features noncaseating granulomas in many body regions. Sinonasal involvement is rare but is also suspected to be underreported. Case presentation We present the case of a 39-year-old woman who was incidentally diagnosed with isolated sarcoidosis involving the middle turbinates. Histopathologic examination of resected concha bullosa material and an extensive panel of diagnostic tests revealed a diagnosis of isolated sarcoidosis. Since no systemic manifestations were detected, topical corticosteroid (nasal spray was administered in the postoperative period. Throughout the 12 months after surgery, the patient remained free of symptoms and all nasal endoscopy examinations were normal. Conclusion Although isolated nasal involvement of sarcoidosis is rare, otorhinolaryngologists should consider this condition in a differential diagnosis for sinonasal complaints.

    We evaluated the magnetic resonance imaging (MRI) of the lacrimal gland in 18 patients with sarcoidosis. All the cases were imaged by conventional spin-echo technique using a 1.5 T super-conductive MR system by General Electric. We identified enlargement of the lacrimal gland in 7 patients. The signal intensity of lacrimal glands in these cases were characterized by isointensity on T1-weighted and proton density image and by high intensity on T2-weighted images. Hilar lymphadenopathy was present in 5 of them. Other ocular disorders related to sarcoidosis were present in 15 patients. Enlargement of the lacrimal gland was correlated with retinal vasculitis and not with hilar lymphadenopathy. (author).

    Objective For lung cancer complicated with sarcoidosis, there are no exact features that indicate whether lymphadenopathy is metastatic. This makes the validity of surgery uncertain for clinicians. The aim of this study was to clarify the clinical features of pulmonary sarcoidosis complicated by lung cancer, especially from the viewpoint of evaluating lymphadenopathy. Methods We retrospectively reviewed medical records from 2004 to 2013 at our institution, and 18 patients who were diagnosed with sarcoidosis and lung cancer were thus found to be eligible. We investigated the relationship between the clinical and pathological findings of their swollen lymph nodes. Results Of 18 patients, 11 conducted surgery, and the postoperative pathological evaluation of swollen lymph nodes was done in 8 of the patients. Postoperative N factor in all these patients was 0, even though lymphatic metastasis had been suspected preoperatively because of the unbalanced distribution of lymphadenopathy or the accumulation of fluorodeoxyglucose. Conclusion In patients with lung cancer complicated by sarcoidosis, the clinical assessment of the state of lymphadenopathy is difficult to make. However, as many of them tend to be benign, we suggest that surgical resection should be considered for a complete cure in the absence of any remote metastasis.

    Sarcoidosis is an unexplained systemic granulomatosis. Bone localizations of the disease are rare. We report a maxillary localization. A 35-year-old patient consulted for facial dysmorphia first observed 2 years before. This swelling was associated to nodular panniculitis lesions and xerostomia. The facial asymmetry was due to maxillary gingival and alveolar swelling. It was associated with scarring in the legs and a purple nodular facial lesion. Lip and jaw biopsies revealed epithelioid and giant cell granulomas without caseous necrosis. The panoramic dental X-ray showed diffuse horizontal alveolar ridge lysis and CT scan revealed an osteolytic lesion of the right maxilla associated to a bone-condensing lesion of the left hemi-mandible. The diagnosis of sarcoidosis is made in case of epithelioid and giant cell granulomas without caseous necrosis and the ruling out of other possible diagnoses, including tuberculosis. Bone involvement is rare; face and maxillary localization are extremely rare. The recommended treatment is corticosteroids. Facial remodeling surgery is not recommended.

    Sarcoidosis is a juvenile systemic granulomatosis. Its polymorphic clinical presentation depends on its different localisations, thoracic and extrathoracic. The role of imaging is very important for all localisations; but for mediastinopulmonary involvement, which is the most frequent (>90% of cases), it plays a major role in detecting the disease, diagnosing it, its prognosis, decision-making regarding treatment of it and in the monitoring of its development. Standard radiography, which sometimes detects the disease, forms the basis for its four-stage prognostic classification. CT scanning enables the study of mediastinal and hilar lymphadenopathy and the study of parenchyma, making it possible to identify micronodules of lymphatic distributions, alveolar opacities, septal lines, ground-glass hyperintensities, nodules surrounded by a ring of satellite micronodules, peribronchovascular thickening; all potentially reversible lesions. Elsewhere, it highlights irreversible fibrous lesions: hilar peripheral linear opacities; septal linear opacities; bronchial distortion, honeycomb destruction or even perihilar fibrotic masses. Less frequently we can visualise bronchiolar or cystic involvement. Benign in most cases, the sarcoidosis prognosis becomes bleaker in the event of hemoptysis, Aspergillus colonisation or before the onset of pulmonary hypertension.

    Full Text Available Most of the studies have shown a higher risk for subclinical and clinical hypothyroidism, antithyroid autoantibodies [overall antithyroid peroxidase antibodies (TPOAb], and in general, thyroid autoimmunity, overall in the female gender in patients with sarcoidosis (S. A significantly higher prevalence of clinical hypothyroidism and Graves’ disease was also described in female S patients with respect to controls. Gallium-67 (Ga-67 scyntigraphy in S patients, in the case of thyroid uptake, suggests the presence of aggressive autoimmune thyroiditis and hypothyroidism. For this reason, ultrasonography and thyroid function should be done in the case of Ga-67 thyroid uptake. In conclusion, thyroid function, TPOAb measurement, and ultrasonography should be done to assess the clinical profile in female S patients, and the ones at high risk (female individuals, with TPOAb positivity, and hypoechoic and small thyroid should have periodically thyroid function evaluations and suitable treatments.

    Full Text Available The present report describes a 60-year-old Caucasian woman who presented with progressive dyspnea, cough and wheeze. A computed tomography scan of the chest showed innumerable bilateral inflammatory pulmonary nodules with bronchovascular distribution and a mediastinal and hilar infiltrative process with calcified lymphadenopathy leading to narrowing of lobar bronchi and pulmonary arteries. An echocardiogram revealed pulmonary hypertension. Bronchoscopy showed left vocal cord paralysis and significant narrowing of the bilateral bronchi with mucosal thickening and multiple nodules. Transbronchial biopsy was compatible with sarcoidosis. Despite balloon angioplasty of the left lower lobe and pulmonary artery, and medical therapy with oral corticosteroids, her symptoms did not significantly improve. To the authors’ knowledge, the present report describes the first case of pulmonary sarcoidosis resulting in major airway, vascular and nerve compromise due to compressive lymphadenopathy and suspected concurrent granulomatous infiltration. Its presentation mimicked idiopathic mediastinal fibrosis.

    TNF α antagonists (anti-TNF α) are widely used in inflammatory rheumatic diseases: rheumatoid arthritis (RA) and spondylarthropathy (SpA). The efficacy of the anti-TNF α monoclonal antibodies was also observed in unresponsive sarcoidosis to conventional therapy. In contrast, sarcoidosis in patients with inflammatory rheumatic disease treated with anti-TNF α keep on growing, with a suspected role of anti-TNF α in this pathological process. We presented here two cases of sarcoidosis developing while the patient was on adalimumab (ADA) therapy for inflammatory rheumatic disease. In one case, the reintroduction of ADA led to increase in symptomatology. We also analyzed the 16 other cases of sarcoidosis developing under ADA treatment published in literature, mostly in RA patients. These cases show a possible paradoxical effect of ADA in sarcoidosis development in patients treated with anti-TNFα monoclonal antibodies. The iatrogenic mechanism remains unclear. These cases underline the importance of a drug-induced etiology survey facing any symptomatology suggesting the development of sarcoidosis in patients treated with anti-TNF α for an inflammatory rheumatic disease.

    2012-10-01

    Full Text Available Abstract Background Scar sarcoidosis is a rare and uncommon but specific cutaneous manifestation of sarcoidosis. In general it arises in pre-existing scars deriving from mechanical traumas. As most surgeons dealing with scars might not be aware of cutaneous sarcoidosis and its different types of appearance the appropriate staging and treatment might be missed or at least delayed. To our knowledge this is the first case in literature of scar sarcoidosis on a finger. Case presentation We present a case of a 33-year-old carpenter who developed scar sarcoidosis on his right index finger 4 years after the tendon of the long digital flexor got accidentally cut by an angle grinder. He was referred due to a swelling of the finger suspected to be a malignant soft tissue tumour. The circumference of the affected finger had almost doubled, adding up to 94 mm. Incision biopsy revealed typical noncaseating granulomas. Further investigation showed a systemic extent of the disease with involvement of the lung. A systemic treatment with oral steroids led to an almost full regression of the swelling with restoration of function and resolution of lung infiltrates. Conclusion In case of a suspicious and/or progressive swelling a definite diagnosis should be achieved by biopsy within a short time to enable a proper treatment. If scar sarcoidosis is proven further investigation is necessary to exclude a systemical involvement. A surgical treatment of the swelling is not indicated.

    2013-04-01

    Acute vision loss is a devastating problem for patients and a challenging diagnostic dilemma for Emergency Physicians. This chief complaint is one in which we must be adept at quickly evaluating and initiating either care or referral. This case reviews the approach to acute vision loss and shows the importance of expanding the differential in atypical and complex presentations. A 31-year-old, previously healthy, white woman presented to the Emergency Department (ED) with 1 day of painless right eye vision loss. Ocular ultrasound and slit-lamp examination were unremarkable. Fundoscopic examination revealed retinal hemorrhages and papillitis. Her chest X-ray study was significant for bilateral hilar adenopathy, and subsequent lymph node biopsy confirmed the diagnosis of sarcoidosis. Although sarcoidosis is more common in African Americans, it must be considered in all patients in the appropriate clinical context. Sarcoidosis is an important diagnosis to include on the differential of many chief complaints that present to the ED, including acute vision loss and dyspnea. Published by Elsevier Inc.

    Full Text Available To evaluate retrobulbar blood flow characteristics of glaucoma suspects with glaucomatous optic disc appearance (GODA in comparison to healthy control group (CG and primary open angle glaucoma patients (POAG and assess the effect of age.145 patients from a single glaucoma clinic were enrolled and classified into two diagnostic groups (GODA and POAG. Third group of subjects consisted of 67 age matched individuals (CG. Retrobulbar blood velocity measurement in central retinal artery was performed using color Doppler imaging (CDI. CDI images were processed in custom software leading a range of parameter estimates from a continuous waveform signal. The effect of age on the estimated parameters was evaluated with the stepwise forward regression and ANCOVA in which age was used as a continuous factor. One-way ANOVA was used to test for the differences in the CDI parameters between the three considered groups. Correlation between restive index (RI and pulsatility index (PI was assessed with a bilinear fitting guaranteeing no discontinuities in RI intercept estimate. Fisher test was used to assess the applicability of a bilinear PI/RI relationship, while the statistics of the RI intercept estimate were evaluated using the bootstrap.ANCOVA showed significant interaction between age and group (p<0.05 for five out of nine considered CDI parameters. The RI intercept for CG and GODA groups was 0.602±0.047, and 0.574±0.044 respectively, while the RI intercept of 0.934±0.066 was found for the POAG.The observed similarity of CG and GODA group and dissimilarity between GODA and POAG groups in terms of PI/RI relationship is remarkable. Age may play some role in the different mechanisms occurring in blood velocity dynamics in GODA and POAG subjects but it is not a strongly determining factor.

    Presentation of the etiology, pathology, clinical course, radiology and differential diagnostics of skeletal sarcoidosis. Noncaseating epithelioid cell granulomas can trigger solitary, multiple or disseminated osteolysis, reactive osteosclerosis and/or granulomatous synovitis. The incidence of sarcoidosis is 10-12 per 100,000 inhabitants per year. Skeletal involvement is approximately 14 %. Skeletal involvement occurs almost exclusively in the stage of lymph node and pulmonary manifestation. Most cases of skeletal involvement are clinically asymptomatic. In the case of synovial involvement, unspecific joint complaints (arthralgia) or less commonly arthritis can occur. Typical skin alterations can be diagnostically significant. Punch out lesions osteolysis, coarse destruction and osteosclerosis can occur, which are best visualized with projection radiography and/or computed tomography. Pure bone marrow foci without interaction with the bone can only be detected with magnetic resonance imaging (MRI) and more recently with positron emission tomography (PET), mostly as incidental findings. There is a predeliction for the hand and trunk skeleton. Skeletal tuberculosis, metastases, multiple myeloma, Langerhans cell histiocytosis and sarcoid-like reactions in solid tumors must be differentiated. The key factors for correct diagnosis are thorax radiography, thorax CT and dermatological manifestations. (orig.)

    The lesions of sarcoidosis generally show relatively high Ga-67 uptake and the usefulness of scintigraphy using this agent in the evaluation of lesion activity is well known. In this report, we assessed characteristic uptake of Ga-67 in intrathoracic lymph nodes, the shape of which resembled the Greek letter Lambda (Lambda sign) and a symmetrical accumulation in bilateral lacrimal and salivary glands which resembled a Panda face (Panda sign) in patients with sarcoidosis. Our review of Ga-67 scans obtained from 15 patients with sarcoidosis and 1,779 patients with other disorders during the past 3 years revealed that the simultaneous presence of both Lambda and Panda signs was specific to patients with sarcoidosis and was not found in patients with various other disorders, although one of these signs might be observed in patients without sarcoidosis. When Lambda-like sign was observed, chest radiogram or CT was necessary for the differential diagnosis of sarcoidosis. Panda sign was observed frequently among patients who had previously received irradiation of the neck. Our results confirmed that sarcoidosis must be suspected when both Lambda and Panda signs were observed. (author).

    To report two patients with sarcoidosis initially presenting with cicatrizing conjunctivitis. Both patients with chronic conjunctivitis were referred for further management. The first patient had conjunctival granulomas, subepithelial fibrosis, and forniceal foreshortening. The second patient had extensive upper and lower conjunctival scarring with forniceal foreshortening and symblepharon formation of both eyes. Conjunctival biopsy specimens revealed noncaseating granulomas. Immunofluorescein studies were negative for immunoreactant deposition in the basement membrane. Because of further diagnostic evaluations, sarcoidosis was determined to be the final cause of the cicatrizing conjunctivitis. Sarcoidosis should be included in the differential diagnosis of cicatrizing conjunctivitis. Recognition of the characteristic noncaseating granulomas in the conjunctival biopsy and initiation of the appropriate evaluations are essential in establishing the diagnosis and determining the extent of systemic involvement.

    A 66-year-old woman, who was diagnosed with iritis, visited our hospital due to general malaise. A blood analysis revealed hypercalcemia. Computed tomography revealed mediastinal and hilar lymph node hyperplasia. Moreover, 67Gallium scintigraphy demonstrated strong accumulation in the lesions, suggesting sarcoidosis. A core needle biopsy (CNB) of the hypoechoic areas of the thyroid was performed because the patient refused to undergo a bronchoscopic examination. The scattering of slightly acidophilic epithelioid cell granulomas was observed in the pathological examination of the biopsy specimen. Based on this finding, the patient was diagnosed with sarcoidosis. Although sarcoidosis rarely involves the thyroid gland, in the present case, thyroid CNB was an alternative diagnostic method that allowed a pathological diagnosis to be obtained. PMID:28781308

    Full Text Available Sarcoidosis is a Greek word (Sarco means flesh and Eido means type or like. Cutaneous sarcoidosis occurs in up to one third of patients with systemic sarcoidosis. This disease is characterised by the presence of non – caseating epitheloid cell granulomas in the skin. Cutaneous sarcoidosis presents as a diagnostic challenge to the dermatopathologists due to its varied presentations and almost identical histologic pictures. Hence, exclusion of infectious causes and compatibility with clinical and radiologic picture serve as significant criteria to come up to a diagnosis. Sometimes; skin lesions are the first manifestation of systemic sarcoidosis. This is not a contagious or allergic disease. There is a risk of development of systemic manifestations at a later date; for which a close follow up is a must. We are presenting a case of cutaneous sarcoidosis, which later on progress to sarcoidosis with systemic manifestations.

    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.

    Disorders of calcium metabolism, especially hypercalcemia and hypercalceuria, are common in sarcoidosis. They are caused by extra renal unsuppressed production of 1,25 dihydroxy vitamin D at the level of the sarcoid granuloma. Hormonal changes during pregnancy have a physiological synergistic effect on this mechanism, which is primarily parathyroid hormone (PTH) dependant. However, the combination of primary hypoparathyroidism with hypocalcemia and sarcoidosis is rare. Di George syndrome, is a dysmorphic disorder characterised by aplasia\\/hypoplasia of thymus and parathyroid glands in addition to aortic arch anamolies and facial dysmorphia.

    Sarcoidosis represents a non-caseating, granulomatous disorder of unknown aetiology whose clinical manifestation is heterogeneous and frequently multisystemic. The portion of patients needing systemic treatment varies: though many patients may undergo spontaneous remission, organ-threatening courses demand systemic therapy. Corticosteroids are the first-line treatment option; however, disease´s progression and/or major corticosteroid side effects may require second- and third-line therapeutics. A current stepwise therapeutic algorithm to sarcoidosis that characterizes additive and alternative therapeutic agents is given in the following review. © Georg Thieme Verlag KG Stuttgart · New York.

    Sarcoidosis involving the nervous system probably occurs in about 4% of patients. The usefulness of brain scintigraphy in these cases has been suggested. In this case of cerebral sarcoid granuloma, gallium imaging demonstrated the lesion before treatment and showed disappearance of the lesion after corticosteroid treatment, which correlated with the patient's clinical improvement.

    This study sought to perform a systematic review and meta-analysis to understand the prognostic value of myocardial scarring as evidenced by late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR) imaging in patients with known or suspected cardiac sarcoidosis. Although CMR is increasingly used for the diagnosis of cardiac sarcoidosis, the prognostic value of CMR has been less well described in this population. PubMed, Cochrane CENTRAL, and metaRegister of Controlled Trials were searched for CMR studies with ≥1 year of prognostic data. Primary endpoints were all-cause mortality and a composite outcome of arrhythmogenic events (ventricular arrhythmia, implantable cardioverter-defibrillator shock, sudden cardiac death) plus all-cause mortality during follow-up. Summary effect estimates were generated with random-effects modeling. Ten studies were included, involving a total of 760 patients with a mean follow-up of 3.0 ± 1.1 years. Patients had a mean age of 53 years, 41% were male, 95.3% had known extracardiac sarcoidosis, and 21.6% had known cardiac sarcoidosis. The average ejection fraction was 57.8 ± 9.1%. Patients with LGE had higher odds for all-cause mortality (odds ratio [OR]: 3.06; p sarcoidosis, the presence of LGE on CMR imaging is associated with increased odds of both all-cause mortality and arrhythmogenic events.

    2015-01-01

    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

  6. Dual diagnosis of sarcoidosis and lymphoma.

    2013-06-01

    Sarcoidosis is a multisystem granulomatous disease of unknown origin with pulmonary and extrapulmonary manifestations. Worldwide it is most often diagnosed in the third and fourth decades and most often affects Swedish, Danish and black patients. The association between malignancy and sarcoidosis has not been conclusively proven. Cancer can eventually occur in patients who have an established diagnosis of sarcoidosis for example, in sarcoidosis-lymphoma syndrome. Sarcoidosis can also subsequently develop in an oncology patient. There are multiple obstacles to confirming epidemiologically the linkage between sarcoidosis and malignancy. Histological verification and clinical acumen are needed to avoid misdiagnosis. The 18 fluorodeoxyglucose (18-FDG) PET has failed to provide a non invasive diagnostic method to differentiate neoplasia from benign sarcoid lesions and tissue diagnosis is essential before commencing a new therapeutic intervention in patients with lymphoma.

    Sarcoidosis is a systemic granulomatous disorder with a variety of clinical presentations and radiological appearances. Although it primarily affects the lungs and lymphatics, sarcoidosis potentially involves essentially every organ system. On imaging, sarcoidosis can mimic different disease entities, including primary and metastatic neoplasms, vasculitis, and other granulomatous infections. Definitive diagnosis often requires a combination of clinical, radiological, and histologic information. Imaging plays a crucial role in diagnosis and evaluating response to therapy. This review covers imaging findings in sarcoidosis within each organ system, with an emphasis on the use of imaging in the diagnosis and management of this condition. Copyright © 2016 Elsevier Inc.

    A 61-year-old woman complained of a subcutaneous mass in her right knee. MR images revealed a well-defined subcutaneous mass in the prepatellar region, containing some fluid and foci of short T2. The lesion showed some marginal contrast uptake after an administration of meglumine gadopentetate (Gd-DTPA), consistent with prepatellar bursitis. The pathological specimen, however, revealed subcutaneous sarcoidosis involving the bursa. (orig.)

    The patient was an 8-years-old girl with bilateral hilar lymphadenopathy (BHL) on chest roentogenogram and negativity of tuberculin reaction, but without superficial lymphadenopathy. Serum angiotensin-converting enzyme (ACE) and serum lysozyme were elevated. So sarcoidosis was suspected and WXGa scan, liver biopsy and ophthalmologic examination were performed. WXGa scan disclosed the abnormal accumulation to BHL, but liver biopsy and ophthalmologic examination were negative. Taking into account absence of superficial lymphadenopaty and the patient's age, lymphnode biopsy and another invasive examinations were not performed. None of the examinations suggested malignant disease. Though histological diagnosis was failed, the results of noninvasive examinations as WXGa scan, serum ACE and serum lysozyme intensively supported the diagnosis of sarcoidosis. And after a while, with improvement of BHL and tuberculin reaction, WXGa scan, serum ACE and serum lysozyme were normalized and the inactive change of disease was considered. These noninvasive examinations would be repeatable and more sensitive. So the combination of these noninvasive examinations as WXGa scan, serum ACE and serum lysozyme was considered to be available to diagnosis of sarcoidosis and as an index of disease activity in sarcoidosis.

    Equine sarcoidosis is a rare disorder usually characterized by exfoliative dermatitis, moderate to severe wasting, and sarcoidal granulomatous inflammation of multiple organ systems. It has an unknown aetiopathogenesis. The condition is not related to equine sarcoid. This case report describes generalized cutaneous and systemic sarcoidosis in an 11-year-old Trakehner mare (case A) and in a 7-year-old Dutch Warmblood gelding (case B). Case A was presented with cutaneous sarcoidosis on the head and body and was diagnosed on the basis of histological examination of skin. Case B presented with multiple subcutaneous nodules (2-15 cm in diameter) and the diagnosis was established at postmortem examination. Both horses showed distinctive histology of the skin with extensive lymphohistiocytic infiltration and Langhans-type multinucleated giant cells. Haematology and biochemistry revealed a normal total white blood cell count with a right shift in both horses. Case B was anaemic and had a slightly elevated total protein concentration with hyperglobulinaemia. Both horses were unresponsive to corticosteroids and were euthanized.

  16. Laser therapy for cutaneous sarcoidosis: A review

    2016-03-01

    Full Text Available Sarcoidosis is a systemic, multi-organ disease of unknown etiology characteristically defined by the development of non-caseating granulomas. The development of sarcoidosis has been associated with a number of environmental and microbacterial factors coupled with genetic susceptibility. Depending on the type, location and distribution of disease, sarcoidosis can cause functional impairment, symptomatic distress, scarring and disfigurement. The advent of lasers as precise, minimally destructive surgical tools has allowed for their development as promising alternatives that minimize the morbidity associated with current therapies.In this paper, we reviewed the role of laser therapy in the treatment of cutaneous sarcoidosis. A comprehensive search of the Cochrane Library, MEDLINE and PUBMED databases was performed to identify relevant literatures investigating the role of laser therapy in the treatment of cutaneous sarcoidosis. In our opinion, laser therapy, particularly PDL, appears to be an effective, safe and generally well-tolerated modality for the treatment of cutaneous sarcoidosis and should be considered in patients with localized cutaneous disease that is refractory to conventional treatments. Less is known about the efficacy and tolerability of ablative laser therapy for the treatment of cutaneous sarcoidosis, though the limited data appears promising as well. With that said, however, the data is limited and warrants a need for additional larger, randomized controlled studies to further investigate the utility and efficacy of laser therapy in the treatment of cutaneous sarcoidosis.

    Bone sarcoidosis is rare manifestation of disease usually accompanied with pulmonary involvement. Until today, exact prevalence of bone sarcoidosis is not known, since reported prevalence varies widely depending on the studied population and the used diagnostic techniques. To determine the prevalence of bone involvement and distribution pattern in active chronic sarcoidosis by using FDG PET/CT. Between January 2010 and December 2011, 98 patients with chronic sarcoidosis and presence of prolonged symptoms or other findings suggestive of active disease were referred to FDG PET/CT examination. Active disease was found in 82 patients, and they all were screened for presence of bone sarcoidosis on FDG PET/CT. All patients also underwent MDCT and assessment of serum ACE level. Bone sarcoidosis was present in 18/82 patients with active sarcoidosis. FDG uptake in bones was focal in 8 (44.4%), diffuse in 6 (33.3%) and both diffuse and focal in 4 (22.2%) patients. CT indicated bone abnormalities only in 5% patients. Osseous involvement was present in: pelvis (61.1%), vertebrae (44.4%), ribs (27.8%) and bone marrow (16.7%). Some patients had two or more locations of disease. Follow-up FDG PET/CT showed normal findings in two patients, same localization of active disease in four patients and progression of disease in one. In patients with active chronic sarcoidosis 22% of patients had osseous abnormalities on FDG PET/CT that mostly were not detected on CT.

    2011-01-01

    Full Text Available Purpose: To report an undiagnosed case of systemic sarcoidosis manifesting with bilateral acute posterior multifocal placoid pigment epitheliopathy (APMPPE. Case Report: A 26-year-old Caucasian man was referred for management of unilateral visual loss together with a paracentral scotoma developing 2 weeks after a flu-like syndrome. Clinical signs and ancillary diagnostic investigations suggested APMPPE. Laboratory tests demonstrated elevated serum angiotensin converting enzyme and lysozyme levels. Chest CT-scan disclosed moderate hilar lymph node calcifications but QuantiFERON-TB gold test was negative and bronchoalveolar lavage and biopsies were unremarkable. Accessory salivary gland biopsy disclosed epithelioid and gigantocellular granuloma formation without caseum, confirming a diagnosis of sarcoidosis. The fellow eye was involved a few days later and the patient complained of dyspnea. Echocardiography disclosed severe granulomatous myocardial infiltration and high dose corticosteroids and intravenous cyclophosphamide were initiated. Systemic treatment controlled both cardiac and ocular lesions, and was tapered accordingly. Conclusion: The constellation of "white dot syndromes" and systemic symptoms necessitates a general work-up to exclude granulomatous disorders such as sarcoidosis or tuberculosis. Delayed diagnosis of cardiac sarcoidosis may have life-threatening consequences and the ophthalmologist may be the first physician to diagnose the condition.

    Sarcoidosis is a systemic disorder of unknown cause that is characterized by the presence of noncaseating granulomas. The radiological findings associated with sarcoidosis have been well described. The findings include symmetric, bilateral hilar and paratracheal lymphadenopathy, with or without concomitant parenchymal abnormalities (multiple small nodules in a peribronchovascular distribution along with irregular thickening of the interstitium). However, in 25% to 30% of cases, the radiological findings are atypical and unfamiliar to most radiologists, which cause difficulty for making a correct diagnosis. Many atypical forms of intrathoracic sarcoidosis have been described sporadically. We have collected cases with unusual radiological findings associated with pulmonary sarcoidosis (unilateral or asymmetric lymphadenopathy, necrosis or cavitation, large opacity, ground glass opacity, an airway abnormality and pleural involvement) and describe the typical forms of the disorder as well. The understanding of a wide range of the radiological manifestations of sarcoidosis will be very helpful for making a proper diagnosis.

    Sarcoidosis is an inflammatory disease characterized by non-caseating granulomas in the absence of other autoimmune processes, infectious diseases, or foreign agents. The etiology of sarcoidosis is not completely understood. Several organ systems can be affected, of which the most frequently involved include the lungs and lymph nodes. Intra-abdominal sarcoidosis is less common, but can be found in the absence of pulmonary or lymphatic disease. Intra-abdominal sarcoidosis is most often asymptomatic. However, long-standing unrecognized disease can result in life-threatening complications. The identification, monitoring and prevention of these complications will be discussed, with emphasis on both clinical and histological presentations of intra-abdominal sarcoidosis.

    In recent years we have observed with increasing frequency granulomatous papular lesions involving the knees, for which we proposed the term papular sarcoidosis of knees. To evaluate the clinicopathological features of papular sarcoidosis of the knees. Patients with papular lesions of the knees and histopathologically sarcoid granulomas were included in the study. Systemic sarcoidosis was investigated in all cases. Clinical charts were retrospectively retrieved. Biopsy specimens were evaluated under polarized light to detect foreign bodies. Fifty-three patients fulfilled inclusion criteria. In 36 cases systemic sarcoidosis was diagnosed and these cases were considered as papular sarcoidosis of the knees. Foreign particles were observed in 21 of these 36 patients. In only 9/36 patients did the activity of systemic disease persist over two years. In 17 cases sarcoidosis could not be demonstrated during follow-up. Papular sarcoidosis of the knees can be considered a relatively frequent form of cutaneous sarcoidosis usually present at the beginning of the disease that can be useful for the diagnosis of sarcoidosis. It is mainly observed in acute forms of sarcoidosis and can be considered a sign of good prognosis.

    Sarcoidosis is a multisystem inflammatory disease that manifests as noncaseating granulomas, commonly in the lungs and intrathoracic lymph nodes. Subcutaneous manifestations of sarcoidosis that are caused by granulomas are referred to as specific for sarcoidosis, whereas other lesions are considered nonspecific. The authors present "sarcoidosis nodule formation on the lateral nasal osteotomy lines" in a sarcoidosis patient undergoing rhinoplasty surgery as a rare patient. V.

    Laryngeal sarcoidosis is a rare manifestation of systemic sarcoidosis. It affects mainly the supraglottic larynx. Involvement of the glottic and subglottic levels are exceptional. We present the case of a 56-year-old man with a 2-year history of systemic sarcoidosis, involving the mucosa of paranasal sinuses, a joint, and mediastinal lymph nodes, who developed laryngeal sarcoidosis. We emphasize the CT appearance of laryngeal sarcoidosis. (orig.)

    Sarcoidosis and amyloidosis are both multisystem disorders, which may involve the heart; however, isolated cardiac disease is rare. Diagnosis of cardiac sarcoidosis and amyloidosis is crucial because the patient prognosis is dependent on cardiac involvement and early treatment. Echocardiography is the first line imaging modality in the diagnostic work-up of both diseases, possibly giving hints towards the correct diagnosis. Besides myocardial biopsy and radionuclide studies cardiac magnetic resonance imaging (MRI) is routinely performed in patients suspect of having infiltrative cardiomyopathy. The T1 mapping procedure is currently being evaluated as a new technique for detection and quantification of global myocardial enhancement, as seen in cardiac amyloidosis. Sensitivities and specificities for detection of cardiac sarcoidosis and amyloidosis can be significantly improved by MRI, especially with late gadolinium enhancement (LGE) imaging. In cardiac sarcoidosis the use of LGE is outcome-related while in amyloidosis analysis of T1-mapping may be of prognostic value. If cardiac involvement in sarcoidosis or amyloidosis is suspected cardiac MRI including LGE should be performed for establishing the diagnosis. (orig.)

    Full Text Available Primary mammary fibromatosis is a rare skin condition which can arise after trauma or previous surgery. The exact etiology is unknown. Very few cases have been reported in literature and the main emphasis is to differentiate this condition from breast carcinoma. We report here an unusual case of a 60 year old female who presented with skin lesion which clinically looked sarcoid with history suggestive of sarcoidosis, but on histopathology fibromatosis of breast was revealed. Complete work up ruled out any carcinomatous changes. Surgical excision of the lesion was done with no recurrence seen in one year follow up period.

    The molecular basis of sarcoidosis phenotype heterogeneity and its relationship to effective treatment of sarcoidosis have not been elucidated. Peripheral samples from sarcoidosis subjects who participated in a Phase II study of golimumab [anti-tumour necrosis factor (TNF)-α] and ustekinumab [anti-interleukin (IL)-12p40] were used to measure the whole blood transcriptome and levels of serum proteins. Differential gene and protein expression analyses were used to explore the molecular differences between sarcoidosis phenotypes as defined by extent of organ involvement. The same data were also used in conjunction with an enrichment algorithm to identify gene expression changes associated with treatment with study drugs compared to placebo. Our analyses revealed marked heterogeneity among the three sarcoidosis phenotypes included in the study cohort, including striking differences in enrichment of the interferon pathway. Conversely, enrichments of multiple pathways, including T cell receptor signalling, were similar among phenotypes. We also identify differences between treatment with golimumab and ustekinumab that may explain the differences in trends for clinical efficacy observed in the trial. We find that molecular heterogeneity is associated with sarcoidosis in a manner that may be related to the extent of organ involvement. These findings may help to explain the difficulty in identifying clinically efficacious sarcoidosis treatments and suggest hypotheses for improved therapeutic strategies. © 2017 British Society for Immunology.

    Pulmonary sarcoidosis which predominantly affects the lower lung fields is relatively rare. We performed this study to clarify the clinical manifestations of this type of sarcoidosis. Over a period of 13 years, we diagnosed pulmonary sarcoidosis in 119 patients. Among these, we reviewed the clinical characteristics of 9 patients (3 men, 6 women, mean age 62 years) with pulmonary lesions predominantly affecting the lower lung fields. Four patients had a history of dust inhalation and 6 had symptoms of dyspnea. All patients had ocular lesions and 5 had cutaneous lesions. Serum KL-6 levels were elevated in all patients, whereas angiotensin-converting-enzyme (ACE) levels were elevated in 3. Pulmonary function tests revealed stenosis in 4 patients, and decreased diffusion capacity in 7. Chest CT findings in the lower lung fields revealed bronchovascular thickening, micronodular opacities in the vessels and chest wall, and interlobular septal thickening in 8 patients; ground-glass opacities in 5; curvilinear shadows in 4; and patchy shadows, traction bronchiectasis, and pleural effusion in 3. Histopathologic findings of lung biopsy specimens featured granulomas in all patients, and pulmonary interstitium fibrosis and small round-cell infiltration in the alveoli of most patients. Patients with sarcoidosis affecting the lower lung fields often had symptoms of dyspnea, extrapulmonary lesions in the eye and/or on the skin, and elevated serum KL-6 levels but not ACE. Chest CT showed findings typical of sarcoidosis, such as lymphatic distribution, but also showed unusual findings such as ground-glass opacities, curvilinear shadows, patchy shadows, traction bronchiectasis and pleural effusion. We speculated that 1 patient with ground-glass opacities and traction bronchiectasis without lymphatic distribution on CT, and fibroblastic foci with active alveolitis histopathologically, had complications of a different type of interstitial pneumonia.

  12. Sarcoidosis, cancer and molecular mimicry.

    2013-01-01

    Molecular mimicry seems to be the most important factor for the heterogeneous clinical presentation and the immunopathogenesis of sarcoidosis. Molecular mimicry may occur as a result of altered activity of oncogenes. This can lead to crossed-type mediated body reactions targeting structurally similar sections or regions from the tissue homeostasis. Available data suggest that structural analogy between tissue and foreign or de novo-appearing peptides is not always reliable. Nevertheless, lack of amino acid identity between the tissue and the de novo-generated tumour antigens does not exclude the phenomenon of molecular mimicry as the major generator of sarcoidosis. There is growing evidence of the mimicry phenomena, caused not only by the similarity between the amino acids but also between the elements which connect segments in the immunological cascade and which may also be affected by external factors. Molecular mimicry may occur between two identified peptides having similar antigenic surfaces (transitory or not), in the absence of a primary homology in amino acid sequence. As far as tumour antigens are concerned, a structural analogy to the de novo-appearing tumour antigens is more likely than transitory imitation resulting from the additional interference of other physical forces. Further research should be performed to confirm, or reject, the transitory imitation thesis or hypothesis.

    A 52-year-old man was admitted to our hospital with chief complaints of fever, general fatigue, and weight loss. A chest roentgenogram showed hyperinflation and many small nodular shadows in both lung fields. A chest CT scan showed centrilobular shadows distributed equally over all lung fields. Examination of a transbronchial lung biopsy specimen revealed a small non-caseating granuloma composed of a giant cell of Langhans type, epithelioid cells, and a few lymphocytes. There was a dark red eruption about 1 cm in diameter on the right forearm, which had been present for a few years, to the best of the patient's memory. Examination of a skin biopsy specimen revealed many non-caseating granulomas composed of epithelioid cells. Uveitis developed about 2 months after admission. Our diagnosis was sarcoidosis. Steroid therapy was started. The patient's symptoms rapidly disappeared and a chest roentgenogram showed remarkable improvement. We believe this was a very peculiar case of sarcoidosis: the patient had systemic symptoms only, and roentgenographic examinations showed hyperinflation and centrilobular shadows distributed over all lung fields.

    Despite accumulating reports on the clinical value of {sup 18}F-fluoro-2-deoxyglucose positron emission tomography ({sup 18}F-FDG PET) and magnetic resonance imaging (MRI) in the assessment of cardiac sarcoidosis, no studies have systematically compared the images of these modalities. Twenty-one consecutive patients with suspected cardiac sarcoidosis underwent cardiac examinations that included {sup 18}F-FDG PET and MRI. The association of {sup 18}F-FDG PET and MRI findings with blood sampling data such as serum angiotensin converting enzyme levels was also evaluated. Eight of 21 patients were diagnosed as having cardiac sarcoidosis according to the Japanese Ministry of Health and Welfare Guidelines for Diagnosing Cardiac Sarcoidosis. Sensitivity and specificity for diagnosing cardiac sarcoidosis were 87.5 and 38.5%, respectively, for {sup 18}F-FDG PET, and 75 and 76.9%, respectively, for MRI. When the {sup 18}F-FDG PET and MRI images were compared, 16 of 21 patients showed positive findings in one (n = 8) or both (n = 8) of the two modalities. In eight patients with positive findings on both images, the distribution of the findings differed among all eight cases. The presence of positive findings on {sup 18}F-FDG PET was associated with elevated serum angiotensin-converting enzyme levels; this association was not demonstrated on MRI. Both {sup 18}F-FDG PET and MRI provided high sensitivity for diagnosing cardiac sarcoidosis in patients with suspected cardiac involvement, but the specificity of {sup 18}F-FDG PET was not as high as previously reported. The different distributions of the findings in the two modalities suggest the potential of {sup 18}F-FDG PET and MRI in detecting different pathological processes in the heart. (orig.)

    Although, the diagnosis and evaluation of sarcoidosis has traditionally remained confined to the chest, its multi-system nature has been widely recognized. Radiological features of pulmonary sarcoidosis are well known but extra-pulmonary manifestations can produce a plethora of non-specific imaging findings that can affect subcutaneous tissue, and the neurological, cardiac, gastrointestinal, urological, liver, spleen, and skeletal systems. In the literature, there are various case reports and specific system reviews but there are few reviews that encompass all the extra-pulmonary manifestations. In this paper, we comprehensively review the imaging features of extra-pulmonary sarcoidosis with characteristic features as well as atypical presentations. In addition, we discuss the emerging role of nuclear medicine in sarcoidosis.

    Gastric involvement is the least rare among digestive localizations of sarcoidosis, as well in adults as in children. When it is to be seen at the beginning of the disease, it may cause difficulties in the diagnostic, especially with Crohn's disease. Gastric ulcers were detected in a 12 year-old girl, of African origin, who complained about epigastric pain. Eighteen months later, diarrhea, poor growing, uveitis and inflammatory biological signs led to a probable diagnostic of Crohn's disease. Endoscopy seemed to confirm this diagnostic with granulomatous lesions on gastric biopsies. The absence of radiological anomalies of the digestive tract and the poor efficiency of the medical treatment led to question this diagnosis and to assert that of sarcoidosis. This case allows to emphasize the rare involvement of the digestive tract in sarcoidosis and the aspects common both to Crohn's disease and sarcoidosis.

    Full Text Available Abstract Childhood sarcoidosis is a rare multisystemic granulomatous disorder of unknown etiology. In the pediatric series reported from the southeastern United States, sarcoidosis had a higher incidence among African Americans. Most reported childhood cases have occurred in patients aged 13–15 years. Macrophages bearing an increased expression of major histocompatibility class (MHC II molecules most likely initiate the inflammatory response of sarcoidosis by presenting an unidentified antigen to CD4+ Th (helper-inducer lymphocytes. A persistent, poorly degradable antigen driven cell-mediated immune response leads to a cytokine cascade, to granuloma formation, and eventually to fibrosis. Frequently observed immunologic features include depression of cutaneous delayed-type hypersensitivity and a heightened helper T cell type 1 (Th1 immune response at sites of disease. Circulating immune complexes, along with signs of B cell hyperactivity, may also be found. The clinical presentation can vary greatly depending upon the organs involved and age of the patient. Two distinct forms of sarcoidosis exist in children. Older children usually present with a multisystem disease similar to the adult manifestations, with frequent hilar lymphadenopathy and pulmonary infiltrations. Early-onset sarcoidosis is a unique form of the disease characterized by the triad of rash, uveitis, and arthritis in children presenting before four years of age. The diagnosis of sarcoidosis is confirmed by demonstrating a typical noncaseating granuloma on a biopsy specimen. Other granulmatous diseases should be reasonably excluded. The current therapy of choice for sarcoidosis in children with multisystem involvement is oral corticosteroids. Methotrexate given orally in low doses has been effective, safe and steroid sparing in some patients. Alternative immunosuppressive agents, such as azathioprine, cyclophosphamide, chlorambucil, and cyclosporine, have been tried in adult cases

    A 59-year-old woman with maturity-onset diabetes presented with symmetrical transient polyarthralgia and acido-cetosis. Bilateral hilar adenopathy and erythematous rash on lower limbs were demonstrated. While low-grade chronic meningeal irritation supervened, lymph node biopsy showed typical sarcoidosis. Administration of corticosteroids resulted in reduction of cerebrospinal fluid albumin content and of lymphocytosis in bronchoalveolar lavage. In this patient, sarcoidosis was therefore associated with Löfgren's syndrome and meningitis.

    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

    Full Text Available 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.

    Sarcoidosis is a systemic granulomatous disorder of unknown aetiology with a wide spectrum of radiological appearances and almost invariably pulmonary involvement. Lung involvement accounts for most of the morbidity and much of the mortality associated with sarcoidosis. Imaging contributes significantly to the diagnosis and management of patients with sarcoidosis. In typical cases, chest radiography may be sufficient to establish the diagnosis with little margin of error and CT is not necessary. However, CT can play a critical role in several clinical settings: atypical clinical and/or radiographic findings; normal or near-normal chest radiograph but clinical suspicion of sarcoidosis; and detection of complications. Moreover, in many patients, CT findings are atypical and unfamiliar to most radiologists (e.g. sarcoidosis mimicking other lung diseases and vice versa), and in these cases histological confirmation of the diagnosis is recommended. CT is also useful in assessing disease extent and may help to discriminate between reversible and irreversible lung disease, thus providing critical prognostic information. This review concentrates on the more difficult imaging aspects of sarcoidosis, in particular differential diagnosis and disease complications. (orig.)

  6. Mechanism of granuloma formation in sarcoidosis.

    The formation of noncaseating granuloma is a hallmark of pulmonary sarcoidosis. This review summarizes recent progress made to explain the cellular dynamics within the granuloma structure that may considerably differ between the two clinically distinct variants, that is, acute and chronic sarcoidosis. Compelling evidence exists that in acute but not chronic sarcoidosis CD4 T lymphocytes specifically recognizing the auto-antigen vimentin on human leukocyte antigen-DR3 molecules accumulate in sarcoid granuloma. These so-called TH17.1 cells produce high amounts of the TH17-related cytokines interleukin-17 (IL-17) and IL-22 in addition to interferon-γ. Moreover, regulatory T cells from patients with acute sarcoidosis are ICOS, providing a mechanistic link to the comparably high concentration of IL-10 exclusively found in the airways of these patients. Next to obvious differences in T effector cell and Treg subsets, alveolar macrophages harbor a functional mitochondrial system in acute sarcoidosis patients, while this system is impaired in patients with chronic disease. We provide a comprehensive update on the cellular components and their functional implications in sarcoid granuloma formation, with special emphasis on the specific characteristics of granuloma in acute versus chronic sarcoidosis. Moreover, the specific antigens thought to be involved in both forms of the disease are discussed.

    Severe thoracic sarcoidosis includes manifestations with significant clinical and functional impairment and a risk of mortality. Severe thoracic sarcoidosis can take on various clinical presentations and is associated with increased morbidity. The purpose of this article was to describe the CT findings in severe thoracic sarcoidosis and to explain some of their mechanisms. Subacute respiratory insufficiency is a rare and early complication due to a high profusion of pulmonary lesions. Chronic respiratory insufficiency due to pulmonary fibrosis is a frequent and late complication. Three main CT patterns are identified: bronchial distortion, honeycombing and linear opacities. CT can be helpful in diagnosing some mechanisms of central airway obstruction such as bronchial distortion due to pulmonary fibrosis or an extrinsic bronchial compression by enlarged lymph nodes. An intrinsic narrowing of the bronchial wall by endobronchial granulomatous lesions may be suggested by CT when it shows evidence of bronchial mural thickening. Pulmonary hypertension usually occurs in patients with end-stage pulmonary disease and is related to fibrotic destruction of the distal capillary bed and to the resultant chronic hypoxemia. Several other mechanisms may contribute to the development of pulmonary hypertension including extrinsic compression of major pulmonary arteries by enlarged lymph nodes and secondary pulmonary veno-occlusive disease. Aspergilloma colonization of a cavity is the main cause of hemoptysis in sarcoidosis. Other rare causes are bronchiesctasis, necrotizing bronchial aspergillosis, semi-invasive pulmonary aspergillosis, erosion of a pulmonary artery due to a necrotic sarcoidosis lesion, necrosis of parenchymal sarcoidosis lesions and specific endobronchial macroscopic lesions.

    Full Text Available Tuberculosis (TB is a disease caused by Mycobacterium tuberculosis. Despite the availability of novel therapeutic approaches, TB is considered as one of the leading causes of death due to infectious diseases worldwide. Alveolar macrophages are the first line of defense against M. tuberculosis; they ingest and sequester the bacilli within granulomatous structures. Control and resolution of the infection requires activated T lymphocytes as well as Th1 cytokines. There are two forms of TB: active TB and latent TB. Latent TB is a state in which M. tuberculosis survives in the body without causing overt signs and symptoms. People with latent TB are noncontagious. However, M. tuberculosis can become active in the body, multiply, and cause overt TB. Sarcoidosis, on the other hand, is an autoimmune disease of unknown etiology which can affect multiple systems of the body. Nonspecific constitutional symptoms, such as fever, fatigue, malaise, and weight loss, are present in approximately one-third of patients. Chest X-ray usually shows hilar and mediastinal lymphadenopathy. Although the lungs are the most common sites of inflammation, sarcoidosis can also involve other organs, such as the eyes (intraocular and adnexal, skin, lymph nodes, salivary glands, heart, spleen, liver, and the nervous system. Recent investigations have provided further insights into the genetic basis of sarcoidosis and the way genotype determines the clinical presentation and phenotype of patients. Histopathologic features are usually insufficient for diagnosis of sarcoidosis. Diagnosis of sarcoidosis in endemic areas for TB can become a great challenge. Both TB and sarcoidosis are granulomatous diseases; TB is characterized by caseating granulomas, whereas sarcoidosis is characterized by noncaseating granulomas. New cases of sarcoidosis are increasingly being diagnosed in areas endemic for TB due to increased orientation of physicians and availability of diagnostic modalities

    Full Text Available 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.

    2013-04-01

    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.

    2012-01-01

    Sarcoidosis is a systemic granulomatous disease that primarily affects the lung and lymphatic systems of the body. The diagnosis of sarcoidosis is established on the basis of compatible clinical and radiologic findings, supported by histologic evidence in one or more organs of noncaseating epithelioid-cell granulomas. A diagnosis of sarcoidosis is reasonably certain without biopsy in patients who present with Löfgren's syndrome. In confirmation of sarcoidosis scale lymph node biopsy, endobronchial biopsy, mediastinoscopy, blind tranbronchial needle aspiration and transbronchial lung biopsy or broncho-alveolar lavage were used with diagnostic yields between 60-85%. At present in stage I and II of sarcoidosis the novel technics such as Endoscopic ultrasound-guided, fine-needle aspiration of intrathoracic lymph nodes (EBUS-FNA) and esophageal ultrasound-guided fine-needle aspiration (EUS-FNA) are performed. The combination of these two methods has been reported to provide a diagnostic yield of above 83-90% with about 100% specificity and may obviate the need for mediastinoscopy.

    Sarcoidosis is a multisystem granulomatous disease affecting nervous system in 5% to 10% of patients. Magnetic resonance imaging (MRI) is accepted as the most sensitive method for detecting neurosarcoidosis. However, the most common findings in MRI are the nonspecific white matter lesions, which may be unrelated to sarcoidosis and can occur because of hypertension, diabetes mellitus, smoking, and other inflammatory or infectious disorders, as well. Autopsy studies report more frequent neurological involvement than the ante mortem studies. The aim of this study is to assess electroencephalography (EEG) in sarcoidosis patients without neurological findings in order to display asymptomatic neurological dysfunction. We performed EEG on 30 sarcoidosis patients without diagnosis of neurosarcoidosis or prior neurological comorbidities. Fourteen patients (46.7%) showed intermittant focal and/or generalized slowings while awake and not mentally activated. Seven (50%) of these 14 patients with EEG slowings had nonspecific white matter changes while the other half showed EEG slowings in the absence of MRI changes. We conclude that EEG slowings, when normal variants (psychomotor variant, temporal theta of elderly, frontal theta waves) are eliminated, may be an indicator of dysfunction in brain activity even in the absence of MRI findings. Hence, EEG may contribute toward detecting asymptomatic neurological dysfunction or probable future neurological involvement in sarcoidosis patients. © EEG and Clinical Neuroscience Society (ECNS) 2016.

    Full Text Available Sarcoidosis is classified as an acquired systemic granulomatous disease. Because of the fact that sarcoidosis affects multiple tissues and organs, it is characterized by many potential signs and symptoms, as well as by the presence of non-caseating granulomas in the organs involved. Although oral sarcoidosis is relatively rare, it may however, present in the oral cavity. This report presents a rare case of sarcoidosis with the initial presenting symptom as severe generalized gingival enlargement. The gingival enlargement was treated by gingivectomy.

    Pleural involvement in sarcoidosis is uncommon and appears in several forms. To document the incidence and characteristics of pleural effusion in sarcoidosis patients, a review of the cases diagnosed in our centre between January 2001 and December 2012 was carried out. One hundred and ninety-five patients with sarcoidosis were identified; three (two men and one woman) presented with unilateral pleural effusion (1.5%): one in the right side and two in the left. Two were in stageii and one was in stageiv. The pleural fluid of the two patients who underwent thoracocentesis was predominantly lymphocytic. One of these patients presented chylothorax and the other had high CA-125levels. In general, these effusions are lymphocyte-rich, paucicellular, serous exudates (sometimes chylothorax) and contain proportionally higher levels of protein than LDH. Most cases are treated with corticosteroids, although it may resolve spontaneously. Copyright © 2013 SEPAR. Published by Elsevier Espana. All rights reserved.

    Sarcoidosis is a systemic granulomatous disease of unknown origin that mainly involves lung and skin, but rarely involves subcutaneous tissue. While some studies have reported on CT or MR imaging findings of subcutaneous sarcoidosis, there is only one report on sonographic findings of subcutaneous sarcoidosis, recently published in the US. Familiarity with ultrasonographic findings of subcutaneous sarcoidosis might be helpful for the early diagnosis in patient with palpable nodules and image follow-up for subcutaneous sarcoidosis. Here we report on the sonographic appearance of subcutaneous sarcoidosis involving dermal and subcutaneous tissue over axilla and sole, a case diagnosed as sarcoidosis and improved by steroid treatment, along with a review of the relevant literature.

    Sarcoidosis is a systemic granulomatous disorder of unknown cause. Apparition or flare of previously diagnosed sarcoidosis following hematopoietic stem cell transplantation (HSCT) has rarely been reported. We report a 62-year-old woman who presented a radiological flare of sarcoidosis post-autologous stem cell transplantation for a POEMS syndrome. Imaging findings and lymph node histology, which revealed non-caseating granuloma, were consistent with the sarcoidosis diagnosis. The patient was asymptomatic and was kept free of treatment. Sarcoidosis must be considered ahead of compatible clinicoradiological presentation occurring after HSCT. Sarcoidosis can mimic metastatic cancer or lymphatic relapse. Tissue biopsies and exclusion of differential diagnosis of granuloma diseases are warranted to confirm sarcoidosis diagnosis. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI).

    Full Text Available Five cases of ocular rosacea (one male and four females are reported in this paper. Two of the patients were with keratoconjunctivitis sicca, one with conjunctivitis chronica and blepharitis, one with conjunctivitis chronica and meibomitis, and one with reccurent corneal erosions with meibomitis and chordeloum. In four patients ocular symptoms preceded the occurence of skin lesions. The treatment with oral tetracyclines significantly improved the state of ocular rosacea in four patients, while in one case the changes of the anterior eye segment progressed in more severe state of ulcerative keratitis. It is considered that in almost 20% of the patients with rosacea ocular lesions may precede the skin changes, representing a diagnostic problem. Thus, in those cases multidisciplinary approach is suggested. Such approach is particularly important because of the decrease of morbidity and the prevention of the onset of the eye complications such as drastic worsening of visual acuity, i.e., the blindness.

    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

    Because of the rarity of neuro-ophthalmic sarcoidosis, there are no therapeutic guidelines based on evidence-based medicine for this disorder. Review of literature combined with personal experience. Corticosteroids are the preferred initial therapy for neuro-ophthalmic sarcoidosis. If patients cannot tolerate the requisite dose of corticosteroid needed to control their disease, or if corticosteroids fail to adequately control the disease process, the choices of a second agent are based on the consideration of rapidity of clinical response and the safety profile. Although methotrexate and mycophenolate mofetil are the medications that are often selected after corticosteroid failure, more rapidly acting agents that have been used are infliximab and intravenous cyclophosphamide.

    Sarcoidosis is a systemic disease that histologically typically shows non-caseating granulomas. The most common radiologic finding is hilar and mediastinal adenopathy. Patients with widely disseminated disease may show involvement of the peripheral appendicular skeleton in 1-13% of such cases. A primary skeletal presentation without other manifestations typical of the disease is rare. We present a case of sarcoidosis in a middle-aged Caucasian man in whom the disease presented with widespread lytic lesions in the axial skeleton and long bones, mimicking metastatic disease. There was no involvement of the peripheral skeleton, skin or lungs. (orig.)

    1983-10-01

    Sarcoidosis is a chronic systemic disease of unknown etiology characterized by non-caseating granulomatous inflammation of various organs. The records of 2319 patients with the diagnosis of sarcoidosis were reviewed to determine the incidence of nasal involvement. Seventeen patients or approximately 1% of the patients with sarcoidosis had histologically proven nasal mucosa involvement. These patients had symptoms of nasal crusting, congestion, epistaxis, pain, or anosmia. The clinical findings in these patients included friable nasal mucosa, nasal polyps, or a characteristic submucosal nodularity. Most patients also had abnormal sinus roentgenograms with either thickening of the sinus mucosa or opacification of the sinuses. Biopsy of the nasal mucosa shows typical non-caseating granulomas, but care must be exercised to exclude other causes of granulomatous inflammation of the nasal mucosa including tuberculosis, fungal infections, and other idiopathic granulomatous diseases such as Wegener's granulomatosis and Churg-Strauss syndrome. The treatment of nasal sarcoidosis has consisted of systemic steroids and in some cases topical beclomethasone dipropionate.

    We describe the first case of mediolateral episiotomic sarcoidosis of the deep vaginal tissue, without involvement of the pulmonary parenchyma or pulmonary symptoms. A 68-year-old female was admitted with a vaginal mass that had developed about 1 month prior. On bimanual examination, we found a painful solid mass approximately 4 cm in diameter on the episiotomy line of the deep vaginal tissue. The patient underwent pelvic magnetic resonance imaging on suspicion of a malignancy, and a vaginal true-cut biopsy was performed. The biopsy specimen exhibited non-caseating, granulomatous inflammation and many multinucleated giant cells, strongly suggesting sarcoidosis. We had excluded other granulomatous diseases; a final diagnosis was made of stage-1 sarcoidosis in the deep vaginal mass. A 3-month course of methotrexate (2.5 mg/week) was commenced to treat a flare-up of rheumatoid arthritis. The vaginal mass resolved. To the best of our knowledge, this is the first case of sarcoidosis in a deep vaginal mass without pulmonary parenchymal or other solid-organ involvement.

    Background Sarcoidosis is a chronic multisystem disease of unknown etiology characterized by noncaseating granulomas that most often involves the lungs, but frequently has extrapulmonary manifestations, which might be difficult to treat in individual patients. Objective To review different disease manifestations, focusing on extrapulmonary organ systems, and to provide treatment options for refractory cases. Materials and methods We performed a literature search using Medline and Google Scholar for individual or combined keywords of “sarcoidosis, extrapulmonary, treatment, kidney, neurosarcoidosis, cardiovascular, gastrointestinal, transplantation, musculoskeletal, rheumatology, arthritis, and skin”. Peer-reviewed articles, including review articles, clinical trials, observational trials, and case reports that were published in English were included. References from retrieved articles were also manually searched for relevant articles. Results and conclusion Isolated involvement of a single organ or organ system is rare in sarcoidosis, and thus all patients must be thoroughly evaluated for additional disease manifestations. Cardiac sarcoidosis and neurosarcoidosis may be life-threatening. Clinicians need to assess patients comprehensively using clinical, laboratory, imaging, and histopathological data to recommend competently the best and least toxic treatment option for the individual patient.

    We hypothesized that the prevalence of allergic disorders, characterized by the release of type 2 cytokines (IL-4, IL-5, IL-10), would be lower in sarcoidosis in which there is a dominant type 1 immune response (IL-2, interferon-gamma). The objective was to measure the prevalence of atopy and self-reported asthma in patients with sarcoidosis. Sarcoidosis patients (n = 136, 72 M, age range 22-75), recruited in the outpatient setting, completed a modified European Community Respiratory Health Survey. 123 of these patients provided blood for allergy testing. For the cohort as a whole the self-reported prevalence of asthma ever (21.5%) and asthma attack in the last 12 months (7.5%), was high as was wheezing (42.1%), breathlessness with wheeze (22.3%) and use of an asthma medication (13.1%). The prevalence of atopy was 34%. These data are not different from the previously reported prevalence of asthma and atopy in New Zealand. The same prevalence of asthma symptoms and atopy as in the normal population suggests that the immune system is not skewed away from mounting T helper type 2 immune responses in sarcoidosis. © 2011 The Authors.

We present a 58-year-old African American man with a complicated medical history including long-standing sarcoidosis that has caused him chronic, unrelenting pain for two decades. He initially underwent placement of an intrathecal morphine pump, but recently began complaining of increasing pain. Consequently, he was seen at our hospital for interrogation of his pain pump by the interventional radiologist, and was incidentally noted to have bilateral calcified hilar lymphadenopathy on fluoroscopic imaging. A dedicated chest x-ray confirmed the abnormality, which was consistent with his known diagnosis of sarcoidosis. Sarcoidosis is a complex disease process characterized by noncaseous granulomas that can affect various organ systems, with pulmonary involvement in up to 90% of cases (1. Though sarcoidosis is a diagnosis of exclusion, clinicians should recognize that bilateral hilar lymphadenopathy is highly concerning for the underlying noncaseating granulomatous disease (2.

    Sarcoidosis is a granulomatous disorder of unknown cause characterized by non-caseating granuloma in young adults. Cardiac involvement is rare and range from 2 to 75% depending on diagnostic criteria. Cardiac involvement in sarcoidosis may be asymptomatic or may manifest as rhythm/conduction troubles or congestive heart failure. The diagnosis and treatment of cardiac sarcoidosis may be challenging. However, advances have come in recent years from the use of cardiac MRI and 18FDG-TEP scanner, as well as from the stratification of the risk of ventricular tachycardia/fibrillation. Due to the rarity of the disease, there is no reliable prospective large study to guide therapeutic strategy for cardiac sarcoidosis. Corticosteroids are probably efficacious, in particular in case of atrio-ventricular block or moderate heart failure. Immunosuppressive drugs have not been largely studied but methotrexate could be helpful. In refractory forms, TNF-α antagonists have been used with success.

    The value of high-resolution computed tomography (HRCT) in diagnosing and assessing inflammatory activity in sarcoidosis is well established. The aim of the present study was to address the intra- and inter-observer agreements of the HRCT score by Oberstein et al. [8], and to evaluate the relationship between HRCT findings and disease severity expressed in respiratory functional impairment in sarcoidosis. The clinical records of 80 known sarcoidosis patients visiting the outpatient clinic between January 2000 and August 2001, who underwent a HRCT as well as lung function tests (including exercise testing), were reviewed. Two readers scored the first 60 HRCT images twice. Weighted kappa and intra-class correlation coefficient were used to assess the reliability of the HRCT scoring system. Spearman's rank correlation coefficients and multiple regression analyses were performed to evaluate the relationship between HRCT findings (first reading, reader A) and respiratory functional impairment. Intra- and inter-reader reliability demonstrated good agreement. All HRCT subscores, except enlargement of lymph nodes, were correlated to the FEV{sub 1}, FVC, DLco, Pao{sub 2}max (all p<0.05) and A-aPo{sub 2}max (p <0.001). Furthermore, HRCT abnormalities, but not the chest radiographic stage, were strongly associated with functional parameters. Abnormal changes of lung parenchyma, established by HRCT features, were associated with respiratory functional impairment in sarcoidosis. Moreover, compared with the radiographic stages, HRCT findings appeared to be much more sensitive in depicting respiratory disability, especially abnormal gas exchange. (orig.)

    Sarcoidosis is a granulomatous inflammatory disorder of unclear etiology, which is known to affect multiple organ systems including the lungs, heart, skin, central nervous system, and eyes, among others. For this reason, sarcoidosis represents a systemic medical disorder that is clinically relevant to multiple medical sub-specialties. Despite extensive research, the etiology of sarcoidosis has yet to be elucidated, although most evidence supports that the pathogenetic mechanism of sarcoidosis is an aberrant immune response, driven by an unidentified antigen (or antigens) in genetically susceptible individuals. Multiple candidate etiologic agents, including microbial organisms and environmental agents, have been investigated, but study results are inconclusive. In this review, we describe the known histologic and immunologic features of sarcoidosis and discuss the evidence supporting a role for infectious processes in the pathogenesis of sarcoidosis.

    This review of recent articles on ocular toxicology concentrates on undesirable effects on the eye induced by systemically used xenobiotics. These include color vision deficiencies or visual field deterioration related to antiepileptic drugs, elevated intraocular pressure associated with inhaled corticosteroids, retinal detachments associated with systemic corticosteroids, rifabutin-induced uveitis, cocaine-related retinal hemorrhagic lesions in utero, deferoxamine-related decreases in vision, ocular allergy to bovine-derived collagen, and a large case study of hydroxychloroquine retinotoxicity. Other publications reviewed include a controlled study showing that glucose levels do not seem to alter color vision, a report that intravenous methotrexate can reach clinically meaningful levels in the aqueous humor, and a study showing the effect of systemic pentoxifylline on ocular blood flow and diabetes. With respect to systemic effects of topical ocular medications, there was a case report of apparent systemic exposure to pilocarpine from an Ocusert (Alza Corp., Palo Alto, CA), generalized urticaria after a single application of 1% cyclopentolate, and asthma induced with topical ketorolac. Readers are reminded that no drug achieves ultimate efficacy or ultimate safety. Thus, the decision to employ a given therapy involves a physician's evaluation of its therapeutic index, that is, the ratio between efficacy and toxicity.

    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

    Objective: To analyze radiological findings observed at high-resolution computed tomography in patients with sarcoidosis, and establishing their correlation with pathological findings. Materials and Methods: High-resolution computed tomography findings in ten patients with sarcoidosis were reviewed and correlated with findings in specimens obtained by surgical biopsy or at necropsy of four of such patients. Results: The most frequently observed finding was presence of nodules with perilymphatic distribution, predominating along bronchovascular sheaths and pleural surface, with subpleural nodules and nodular scissurae. Other less frequent findings were ground-glass attenuation and interlobular septa thickening. Conclusion: In general, all the mentioned findings demonstrated anatomopathological correlation with development of granulomas in these regions. (author)

    Sarcoidosis is a multisystem granulomatous disorder of unknown aetiology. The diagnosis is suggested on the basis of wide ranging clinical and radiological manifestations, and is supported by the histological demonstration of non-caseating granulomas in affected tissues. This review highlights the multisystem radiological features of the disease across a variety of imaging methods including multidetector computed tomography (CT), magnetic resonance imaging (MRI) as well as functional radionuclide techniques, particularly 2-[{sup 18}F]-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography/computed tomography (PET/CT). It is important for the radiologist to be aware of the varied radiological manifestations of sarcoidosis in order to recognize and suggest the diagnosis in the appropriate clinical setting.

An electrocardiogram showed first-degree atrioventricular block with complete right bundle branch block. Chest X-ray showed cardiomegaly. Echocardiography showed diffuse and severe hypokinesis of the left ventricle (LV and biventricular enlargement with severe tricuspid regurgitation. Myocardial scintigraphy disclosed a perfusion defect at the ventricular septum and hypoperfusion at the posterior wall and the apex. On cardiac catheterization, pulmonary capillary wedge pressure, right ventricular, and right atrial pressures were elevated. Coronary angiograms were normal. Myocardial biopsy of the right ventricle histologically revealed epithelioid cell granuloma with infiltration of fibrous cells. The patient's symptom and LV function were improved with conventional medical therapy for heart failure. This is a rare case of cardiac sarcoidosis resulting in biventricular failure.

    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.

    TNF blockers are widely used to treat inflammatory rheumatic diseases and also in the treatment of extrapulmonary sarcoidosis. TNFα plays a major role in the development and persistence of sarcoid granulomata. However, recent studies have reported the involvement of anti-TNF therapies in the development of granulomatosis associated with the clinical and radiological features of sarcoidosis. A 54-years-old man with ankylosing spondylitis was treated with etanercept for two years. He was admitted with symptoms of bronchitis associated with radiological evidence of bilateral pulmonary nodules and a right upper lobe infiltrate. Anti-TNF therapy was stopped even though the patient had received 3 months of prophylactic treatment with rifampicin and isoniazid before starting etanercept. Bronchoalveolar lavage excluded infection, particularly tuberculosis. The chest CT-scan showed bilateral pulmonary nodules with peribronchovascular micronodules and enlarged mediastinal lymph nodes. Surgical lung biopsy was performed and revealed non-caseating granulomata. All the data were consistent with a diagnosis of pulmonary sarcoidosis. The patient remained symptomatic despite discontinuation of etanercept for ten months. Corticosteroids were then introduced, leading to a clinical, functional and radiological improvement. This case report underlines the importance of studying the pulmonary complications of TNF blockers. The first priority is to exclude tuberculosis but a diagnosis of sarcoid-like granulomatosis has to be considered. Twenty-three cases have been described in the literature to date.

    Sarcoidosis is an idiopathic multisystem granulomatous disease that commonly involves the skin in 25% of affected patients. 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.

    Introduction. Sarcoidosis, which is a chronic inflammatory granulomatous disease, can mimic different rheumatologic diseases including connective tissue diseases. Antinuclear antibodies are the markers used for connective tissue diseases. Aim. To determine antinuclear antibody frequency and any possible correlation with clinical and laboratory data in sarcoidosis patients. Material and Method. Forty-two sarcoidosis patients, 45 rheumatoid arthritis patients, and 45 healthy volunteers who were followed up in rheumatology outpatient clinic were included in this study. Demographic, clinical, serological, and radiological data of all patients were recorded. Antinuclear antibodies were determined with indirect immunofluorescent method and 1/100 titration was accepted as positive. The cases that were ANA positive were evaluated with immunoblot method. Results. Average age of the 42 patients (10 males) with sarcoidosis was 45.2 (20-70 years), and average disease duration was 3.5 years. ANA positivity was detected in 12 (28.5%) patients with sarcoidosis (1/100 in 10 patients, 1/320 in two patients), in 19 of RA patients (42.2%), and in two of healthy volunteers in low titer (P syndrome and scleroderma diagnosis, respectively. Discussion. The prevalence of ANA in patients with sarcoidosis was found to be significantly higher than healthy control group and lower than RA patients. This result shows that ANA may have an important role in the pathogenesis of sarcoidosis and also could be important in revealing the overlap syndromes of sarcoidosis-connective tissue diseases. Further studies with larger series are necessary in this subject.

    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 disease of unknown etiology, in which granulomas develop in various organs, including the skin, lungs, eyes, or heart. It has been reported that patients with sarcoidosis are more likely to develop panic disorder than members of the general population. However, there are many unknown factors concerning the causal relationship between these conditions. We present the case of a 57-year-old woman who appeared to have panic disorder, as she experienced repeated panic attacks induced by transient complete atrioventricular block, associated with cardiac sarcoidosis. Psychotherapy and pharmacotherapy were not effective in the treatment of her panic attacks. However, when we implanted a permanent pacemaker and initiated steroid treatment for cardiac sarcoidosis, panic attacks were ameliorated. Based on these findings, we diagnosed the patient's symptoms as an anxiety disorder associated with cardiac sarcoidosis, rather than panic disorder. This report highlights the importance of considering cardiac sarcoidosis in the differential diagnosis of panic disorder. This cardiac disease should be considered especially in patients have a history of cardiac disease (e.g., arrhythmia) and atypical presentations of panic symptoms. Panic disorder is a psychiatric condition that is typically diagnosed after other medical conditions have been excluded. Because the diagnosis of sarcoidosis is difficult in some patients, caution is required. The palpitations and symptoms of heart failure associated with cardiac sarcoidosis can be misdiagnosed as psychiatric symptoms of panic disorder. The condition described in the current case study appears to constitute a physical disease, the diagnosis of which requires significant consideration and caution.

    Sarcoidosis is a multisystem, granulomatous disease that most often affects the lungs. The clinical course is highly variable; many patients undergo spontaneous remission, but up to a third of patients progresses to a chronic disease course. The development of pulmonary fibrosis (PF) in a subset of patients with chronic disease has a negative impact on morbidity and mortality. While sarcoidosis-associated PF can be progressive, it is often referred to as “burnt out” disease, a designation reflecting inactive granulomatous inflammation. The immune mechanisms of sarcoidosis-associated PF are not well understood. It is not clear if fibrotic processes are active from the onset of sarcoidosis in predisposed individuals, or whether a profibrotic state develops as a response to ongoing inflammation. Transforming growth factor β (TGF-β) is an important profibrotic cytokine, and in sarcoidosis, distinct genotypes of TGF-β have been identified in those with PF. The overall cytokine profile in sarcoidosis-associated PF has not been well characterized, although a transition from a T helper 1 to a T helper 2 signature has been proposed. Macrophages have important regulatory interactions with fibroblasts, and the role of alveolar macrophages in sarcoidosis-associated PF is a compelling target for further study. Elucidating the natural history of sarcoidosis-associated PF will inform our understanding of the fundamental derangements, and will enhance prognostication and the development of therapeutic strategies.

    Sarcoidosis is a systemic granulomatous disease which predominantly affects the lungs, although granulomas can also involve all other organs, including the heart. Cardiac sarcoidosis (CS) may occur at any stage of the disease and may be the cause of sudden cardiac death, even in a previously asymptomatic patient. The aim of this study was to evaluate the incidence of CS in a large group of patients diagnosed or followed up due to sarcoidosis. We performed a retrospective analysis of patients at our institution discharged with the final diagnosis "sarcoidosis" (ICD-10: D86) from January 2008 to October 2012. Only those with biopsy (from respiratory tract or lymph nodes) confirmed diagnosis of sarcoidosis were included. We then selected the subset of patients with cardiac involvement due to sarcoidosis confirmed by positive magnetic resonance imaging. The study covered 1375 consecutive sarcoidosis patients (51 % men), who were hospitalized during 5 years. Multiorgan disease was detected in 160 cases (11.7 %), and cardiac involvement was found in 64 patients (4.7 % of all), 70.3 % of whom were men. Twelve of those with CS were in stage I, 48 in stage II, and four in stage III. The odds ratio for having cardiac involvement in men compared to women was 2.3 (95 % CI 1.36-4.0, p = 0.002). Cardiac involvement in sarcoidosis was diagnosed in the similar percentage as in previously published data but was significantly more frequently in men.

    2016-09-01

    Up to twenty percent of patients with sarcoidosis develop pulmonary fibrosis, transforming an often benign disease into a highly morbid and potentially fatal one. We highlight the fibrotic pulmonary sarcoidosis phenotype as an area of intense clinical and translational investigation, review recent developments in treatment, and provide a roadmap for future research in sarcoidosis associated pulmonary fibrosis. Granulomatous inflammation in a lymphatic distribution is the hallmark finding of pulmonary sarcoidosis and the nidus for fibrosis. Recent research demonstrates that fibrotic sarcoidosis begins in the setting of persistent, uncontrolled inflammation, and is aided by pro-fibrotic genetic features and immune responses. Comparison to other fibrotic lung diseases also reveals key features that inform our understanding of common pathways in fibrosis. Understanding the mechanisms of fibrotic transformation in sarcoidosis enhances clinical care and facilitates development of novel therapeutic options. The impact of these findings in fibrotic sarcoidosis may be amplified through application to other interstitial lung diseases marked by inflammatory to fibrotic transformation. Important aspects of clinical management of fibrotic sarcoidosis include surveillance for co-morbidities, such as pulmonary hypertension, airway disease, and infection, and assessment for pulmonary disease activity that may benefit from immunosuppression.

  11. Rapidly Progressive Atrioventricular Block in a Patient with Sarcoidosis

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Cardiac sarcoidosis is a major cause of death in patients with systemic sarcoidosis. Cardiac manifestations are seen in 2.3% of the patients. Atrioventricular (AV block is one of the common manifestations of cardiac sarcoidosis. Other presentations of cardiac involvement include congestive heart failure, ventricular arrhythmias, and sudden cardiac death. The presence of AV block in young patients should raise the suspicion of sarcoidosis. AV block may be the only manifestation and patients may not have clinical evidence of pulmonary involvement. Here we describe a young male presented with exercise induced AV block rapidly progressing to complete heart block with recurrent syncope needing urgent pacemaker implantation. Factors that suggested an infiltrative process included his young age, rapidly progressive conduction abnormalities in the ECG in the absence of coronary disease, and previous history of cutaneous sarcoidosis.

  12. Recognition of distinctive patterns of gallium-67 distribution in sarcoidosis

    Sulavik, S.B.; Spencer, R.P.; Weed, D.A.; Shapiro, H.R.; Shiue, S.T.; Castriotta, R.J. (Univ. of Connecticut School of Medicine, Farmington (USA))

    1990-12-01

    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.

    2014-05-01

    Full Text Available The association of sarcoidosis with multiple myeloma is not well known. Including this case report, 12 cases of patients with both sarcoidosis and multiple myeloma have been reported in the literature. The skeletal lesions of both conditions have many clinical and radiological similarities, and unless clinicians are aware of the association and the possibility of dual pathologies, the diagnosis of multiple myeloma in patients known with sarcoidosis may be missed. We present a case of a patient known with longstanding sarcoidosis who was found to have multiple lesions on magnetic resonance imaging (MRI involving the pelvis and both proximal femurs. Histological analysis revealed the presence of both non-necrotising granulomas consistent with sarcoidosis, and sheets of plasma cells consistent with a plasma cell neoplasm.

    Purpose Sarcoidosis is a non-caseating granulomatous disease for which a role for infectious antigens continues to strengthen. Recent studies have reported molecular evidence of mycobacteria or propionibacteria. We assessed for immune responses against mycobacterial and propionibacterial antigens in sarcoidosis bronchoalveolar lavage (BAL) using flow cytometry, and localized signals consistent with microbial antigens with sarcoidosis specimens, using matrix-assisted laser desorption ionization imaging mass spectrometry (MALDI-IMS). Methods BAL cells from 27 sarcoidosis, 14 PPD- controls, and 9 subjects with nontuberculosis mycobacterial (NTM) infections were analyzed for production of IFN-γ after stimulation with mycobacterial ESAT-6 and Propionibacterium acnes proteins. To complement the immunological data, MALDI-IMS was performed to localize ESAT-6 and Propionibacterium acnes signals within sarcoidosis and control specimens. Results CD4+ immunologic analysis for mycobacteria was positive in 17/27 sarcoidosis subjects, compared to 2/14 PPD-subjects, and 5/9 NTM subjects (p=00.008 and p=00.71 respectively, Fisher's exact test). There was no significant difference for recognition of P. acnes, which occurred only in sarcoidosis subjects that also recognized ESAT-6. Similar results were also observed for the CD8+ immunologic analysis. MALDI-IMS localized signals consistent with ESAT-6 only within sites of granulomatous inflammation, whereas P. acnes signals were distributed throughout the specimen. Conclusions MALDI-IMS localizes signals consistent with ESAT-6 to sarcoidosis granulomas, whereas no specific localization of P. acnes signals is detected. Immune responses against both mycobacterial and P. acnes are present within sarcoidosis BAL, but only mycobacterial signals are distinct from disease controls. These immunologic and molecular investigations support further investigation of the microbial community within sarcoidosis granulomas. PMID:22552860

    To determine the specific high-resolution CT features of sarcoidosis in which the observed pattern is predominantly pseudoalveolar. We retrospectively reviewed the HRCT findings in 15 cases in which chest radiography demonstrated pseudoalveolar consolidation. In all 15, sarcoidosis was pathologically proven. The distribution and characterization of the following CT features was meticulously scrutinized: distribution and characterization of pseudoalveolar lesions, air-bronchograms, micronodules, thickening of bronchovascular bundles and interlobular septa, lung distortion, ground-glass opacities and combined hilar and mediastinal lymphadenopathy. Follow-up CT scans were available in three cases after corticosteroid administration. Between one and 12 (mean, 5.6) pseudoalveolar lesions appeared as dense homogeneous or inhomogeneous opacities 1-4.5 cm in diameter and with an irregular margin located either at the lung periphery adjacent to the pleural surface or along the bronchovascular bundles, with mainly bilateral distribution (n=14, 93%). An air-bronchogram was observed in ten cases. Micronodules were observed at the periphery of the lesion or surrounding lung, which along with a thickened bronchovascular bundle was a consistent feature in all cases. Additional CT features included hilar and mediastinal lymphadenopathy (n=14, 93%), thickened interlobular septa (n=12, 80%), and ground-glass opacity (n=10, 67%). Lung distortion was noted in only one case (7%). After steroid administration pseudoalveolar lesions decreased in number and size in all three cases in which follow-up CT was available. The consistent HRCT features of pseudoalveolar sarcoidosis are bilateral multifocal dense homogenous or inhomogenous opacity and an irregular margin located either at the lung periphery adjacent to the pleural surface or along the bronchovascular bundles. Micronodules are present at the periphery of the lesion or surrounding lung. The features are reversible administration.

    The Japanese Ministry of Health and Welfare guidelines (JMHWG) are currently the standard used to diagnose cardiac sarcoidosis. JMHWG incorporate (67)Gallium scintigraphy as a minor criterion, while fasting (18)fluorine-2-fluoro-2-deoxy-D-glucose (FDG) PET is not included. As there is no published data comparing the accuracy of prolonged fasting FDG PET-CT (PF-PET) and Gallium scintigraphy for detecting active cardiac sarcoidosis, we sought to compare these two modalities. We retrospectively reviewed medical records and nuclear images of 76 patients with suspected cardiac sarcoid who had either PF-PET or Gallium scintigraphy between January 2004 and August 2008. Eleven patients were excluded due to inadequate fasting for PF-PET, incomplete records or diagnosis other than sarcoid. Cardiac catheterizations, electrocardiogram interpretations, echocardiography reports, pathology reports, therapeutic interventions, and follow-up findings were correlated to PF-PET and Gallium scintigraphy results. Nuclear images of all patients including controls were reviewed independently by two experienced nuclear physicians blinded to results. Using JMHWG as reference standard, sensitivity, specificity, and accuracy of PF-PET were 85%, 90%, and 86.7% and for Gallium scintigraphy were 15%, 80%, and 42.8%. Relative to Gallium scintigraphy, PF-PET appears to provide greater accuracy for detecting cardiac sarcoidosis. Our findings also highlight the importance of revising JMHWG to incorporate PF-PET and the importance of adequate prolonged fasting prior to FDG PET imaging.

  19. The etiologic role of infectious antigens in sarcoidosis pathogenesis

    2015-01-01

    Sarcoidosis is a granulomatous disease of unknown etiology, characterized by a Th1 immunophenotype, most commonly involving the lung, skin, lymph node and eyes. Molecular and immunologic studies continue to strengthen the association of sarcoidosis with infectious antigens, particularly those derived from Propionibacterium and Mycobacterium species. 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. Th-1 immune responses directed against mycobacterial virulence factors have been detected within sarcoidosis diagnostic bronchoalveolar lavage (BAL). Th1 and Th17 immune responses against propionibacteria have also been reported. More recently, case reports and clinical trials from Japanese, European and American investigators have emerged regarding the efficacy of antimicrobials against Propionibacterium and Mycobacterium species on pulmonary and cutaneous sarcoidosis. While these clinical investigations are not conclusive, they support increasing efforts to identify novel therapeutics, such as antimicrobials, that will impact the observed increase in sarcoidosis morbidity and mortality.

    In this article we describe a 39-year-old man who presented with non-scarring non-scalp alopecia of his limbs as the initial presentation of sarcoidosis. Alopecia is a rare cutaneous manifestation of sarcoidosis. A literature review has found only one other example of sarcoidosis presenting as non-scarring non-scalp alopecia in an area other than the scalp in a patient who was otherwise asymptomatic. Several reported cases have described scarring alopecia of the scalp, which is the area of skin most commonly affected by sarcoidosis. There has been one documented case of sarcoidosis manifesting as total body non-scarring alopecia in a patient who had systemic symptoms of sarcoidosis. Other cases have presented rare cutaneous manifestations of sarcoidosis but in all these cases several other organ systems have been involved, and the patient has had systemic symptoms on presentation or the cutaneous presentation did not include non-scalp non-scarring alopecia. © 2015 The Australasian College of Dermatologists.

    Sarcoidosis is a systemic inflammatory disease of unknown etiology. Osteopontin (SPP1, OPN) is an extra cellular matrix glycoprotein and cytokine with a known role in granuloma formation and in autoimmune and inflammatory diseases. To determine whether plasma OPN levels are elevated in patients with sarcoidosis and compare the frequency of four single nucleotide polymorphism (SNPs) variants in the OPN gene in sarcoidosis patients compared to healthy controls. Demographic and clinical information, radiological studies and pulmonary function tests were evaluated in 113 patients with sarcoidosis and in 79 healthy controls. Blood samples were analyzed for SNPs of the OPN gene and for plasma OPN and CRP levels. Association between clinical features of disease and OPN levels as well as SNP frequencies was determined. Plasma OPN levels were higher in sarcoidosis patients than in healthy subjects, (median: 217 vs 122ng/ml, psarcoidosis patients and controls in the frequency of any of the SNPs evaluated. Presence of lung parenchymal involvement was associated with SNP distribution at rs1126772 (p = 0.02). We found no correlation between SNPs distribution and plasma OPN levels. Osteopontin protein levels are elevated in sarcoidosis. We found no evidence for an association between SNPs on the osteopontin gene and plasma OPN levels or the presence of sarcoidosis, however, an association between genotype and several phenotypic clinical parameters of disease was observed.

    Sarcoidosis is a multisystemic disorder of unknown cause that is characterized pathologically by noncaseating granulomas and predominantly affects the lungs and the lymphatic system, especially intrathoracically. Diagnosis is based on the association of a compatible clinical and radiological presentation, the presence of characteristic histopathological lesions and the exclusion of other potential causes of granuloma. Although the lungs and mediastinal lymph nodes are almost involved, endobronchial nodular lesions of sarcoidosis with lung involvements are rare. We report a case of sarcoidosis with lung involvements and endobronchial nodules as confirmed by bronchial biopsy. © 2014 John Wiley & Sons Ltd.

    2007-09-01

    To present data on hemodynamic changes during dental extractions in 5 patients with cardiac sarcoidosis, performed with electrocardiogram, heart rate, and blood pressure monitoring throughout the procedures, and to discuss the problems relating to the disease and dental extraction. The medical data for 5 patients, including medical records, physician correspondence, and laboratory data before the treatments, were assessed. Seven dental extractions were then performed while monitoring and recording the hemodynamic conditions. Heart rate, blood pressure, rate pressure products, and electrocardiographic findings were analyzed. Finally, posttreatment evaluations of the general and local conditions of the patients were conducted. All dental extractions were performed in nonactive stable periods, with no remarkable hemodynamic changes or complications, while maintaining a stable hemodynamic state throughout the extraction procedure. All patients received a pretreatment supplement of corticosteroid. Wound healing was similar to that in normal patients under antibiotic prophylaxis against infection originating from the dental extraction wound and the original dental lesion. Pretreatment general evaluation of patients with cardiac sarcoidosis should be performed through various examinations and physician consultation, and a stable hemodynamic change during the surgical procedure should be maintained under any hemodynamic monitors. Corticosteroid supplement and antibiotic coverage are also necessary for safe dental extraction and suitable healing.

    2016-01-01

    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.

  6. Coexistence of systemic sclerosis and sarcoidosis.

    Godziszewska, Sabina; Widuchowska, Małgorzata; Kopeć-Mędrek, Magdalena; Kucharz, Eugeniusz Józef

    Coexistence of systemic sclerosis (SSc) and sarcoidosis (SA) is rarely reported; 21 cases only were reported in the English medical literature before 2011. It is suggested that low incidence of overlap syndrome of SSc with SA is resulted from different immune mechanisms involved in pathogenesis of the diseases. In SSc patients, a role of Th2 lymphocytes is suggested while in patients with SA such role is attributed to Th1 lymphocytes. The paper presents a 47-year-old woman suffering from SSc for over 6 years. CT scan of the lungs revealed the nodulus of the right lung and enlarged mediastinal lymphatic nodes. Pathologic evaluation of the nodulus provided basis for diagnosis of sarcoidosis. Diagnosis of SSc was based on clinical and capilaroscopic evaluation as well as detection of anti-topoisomerase I antibodies. In the course of the disease, fibrosis of the lung, pulmonary hypertension and cardiac abnormalities with rhythm disturbances were developed. Treatment included cyclophosphamide, mycophenolate mofetil, sildenafil, losartan. Stabilization of the general state of the patient was achieved.

    2011-05-01

    Full Text Available Depending on the location, dermatoses can produce blemishes that severely impair quality of life and require highly effective treatment that is otherwise used for extensive skin involvement. We report the case of a 39-year-old, otherwise healthy male disfigured by an 8 × 7-cm hypopigmented and centrally atrophic annular plaque with erythematous indurated borders in an area of scar tissue on his forehead. Skin biopsies revealed non-caseating granulomas, and hilar involvement was identified, leading to the diagnosis of systemic sarcoidosis stage II with cutaneous involvement. The lesions proved resistant to multiple therapies, but responded within 4 months to adalimumab with regression of the lesion and inflammatory infiltrate. The visual analogue scale of disease activity decreased from 7/10 to 3.5/10, and the Dermatology Life Quality Index from 16/30 to 3/30 points. In conclusion, TNF-α inhibition can control inflammation and disfigurement by cutaneous sarcoidosis and restore quality of life.

    2017-11-01

    Sarcoidosis is a chronic, multisystemic, granulomatous disorder. Our patient was a 2-year-old girl with multiple airway conditions and a partial response to inhaled and systemic steroids. She was positive for acute phase reactants and negative for antibodies. Polymerase chain reaction revealed atypical Mycobacteria and she was negative for Mycobacterium tuberculosis. Laryngeal sarcoidosis was diagnosed by histopathology in a biopsy of larynx that revealed a chronic granulomatous inflammatory process with Langhans giant cells and acute and ulcerated areas with changes compatible with tuberculosis. Treatment consisted of monthly gammaglobulin for 6 months at doses of 2g/kg body weight, accompanied by Valmetrol™ and methotrexate. Immunomodulation with gammaglobulin was prescribed, with subsequent use of methotrexate-based immunosuppression. Currently, bronchoscopy shows no evidence of granulomas and she is negative for acute-phase reactants.

    Full Text Available Sarcoidosis is a granulomatous disease, characterized microscopically by noncaseating granulomas, which may involve multiple organs; however, the lung, skin, and lymph nodes are commonly affected. Sarcoidosis is a great imitator; in the skin, it presents with different cutaneous manifestations including lupus pernio, infiltrated plaques, maculopapular eruptions, infiltration of old scars, and subcutaneous sarcoidosis. Lymphedema as an initial presentation is extremely rare; cases are reported in African-American but not Asian patients. Lymphedema associated with sarcoidosis may result from lymphatic obstruction by infiltrating sarcoidosis. We present a case where the symptoms and signs of sarcoidosis were improved after treatment with systemic steroids.

    The uptake of gallium-67 by pulmonary sarcoidosis was noted by Langhammer et al. in 1972 and by McKusick et al. in 1973. Heshiki et al. studied the application of this procedure in the diagnosis of sarcoidosis and concluded that although gallium-67 uptake in lungs and hilar regions correlated poorly with clinical activity, its measurement might prove useful in the diagnosis of sarcoidosis and in the measurement of response to therapy. We have undertaken to evaluate further the clinical usefulness of this technique. Thirty-six patients, 27 of whom had sarcoidosis, were given intravenous injections of 3 ml of commercially obtained (/sup 67/Ga) citrate. None were receiving corticosteroid therapy at the time of the initial study. Three days later simultaneous anterior and posterior scans of the thorax and the upper abdomen were performed in the supine position. 1 table.

    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.

  17. Diffuse bronchiectasis as the primary manifestation of endobronchial sarcoidosis

    Paul D. Hiles

    2017-01-01

    Full Text Available Sarcoidosis is an idiopathic disease that most commonly involves the lungs and is characterized by granulomatous inflammation. Bronchiectasis is one pulmonary manifestation of sarcoidosis, although it is almost always observed as traction bronchiectasis in the setting of fibrotic lung disease. A 50-year-old woman was evaluated for chronic cough and bronchiectasis with a small amount of peripheral upper lobe honeycombing and no significant pulmonary fibrosis or lymphadenopathy. After an extensive laboratory and imaging evaluation did not identify a cause of her bronchiectasis, bronchoscopy was performed to assess for primary ciliary dyskinesia and revealed a diffuse cobblestone appearance of the airway mucosa. Endobronchial biopsies and lymphocyte subset analysis of bronchoalveolar lavage fluid were consistent with a diagnosis of sarcoidosis. We believe endobronchial sarcoidosis should be included in the differential diagnosis of patients presenting with bronchiectasis.

    Sarcoidosis is a systemic idiopathic disease characterized by the presence of noncaseating epithelioid granulomas in multiple organs. Thoracic involvement occurs in nearly all patients at some time during the course of the disease. We describe the findings in our patients with this disease using conventional computed tomography (CT) and high resolution CT (HRCT). We analyzed retrospectively the CT studies performed in our unit in 43 patients diagnosed as having sarcoidosis on the basis of biopsy and/or bronchoalveolar lavage. We classified the findings according to their intra parenchymal or extra parenchymal location, observing infrequent features such as pleural and pericardial thickening, lymphadenopathies presenting calcification or at uncommon sites, splenomegaly, laveolar pattern, trabecular pattern and air trapping. In patients with sarcoidosis, conventional CT and HRCT are more useful than plain radiology for the detection and study of the extension of intra parenchymal and extra parenchymal lesions and for the assessment of the disease course. It also serves to guide trans thoracic biopsy, should this procedure be necessary. (Author) 11 refs.

  20. The Prevalence of Antinuclear Antibodies in Patients with Sarcoidosis

    Full Text Available Introduction. Sarcoidosis, which is a chronic inflammatory granulomatous disease, can mimic different rheumatologic diseases including connective tissue diseases. Antinuclear antibodies are the markers used for connective tissue diseases. Aim. To determine antinuclear antibody frequency and any possible correlation with clinical and laboratory data in sarcoidosis patients. Material and Method. Forty-two sarcoidosis patients, 45 rheumatoid arthritis patients, and 45 healthy volunteers who were followed up in rheumatology outpatient clinic were included in this study. Demographic, clinical, serological, and radiological data of all patients were recorded. Antinuclear antibodies were determined with indirect immunofluorescent method and 1/100 titration was accepted as positive. The cases that were ANA positive were evaluated with immunoblot method. Results. Average age of the 42 patients (10 males with sarcoidosis was 45.2 (20–70 years, and average disease duration was 3.5 years. ANA positivity was detected in 12 (28.5% patients with sarcoidosis (1/100 in 10 patients, 1/320 in two patients, in 19 of RA patients (42.2%, and in two of healthy volunteers in low titer (P<0.001. In the subgroup analysis made by immunblot test, one patient had anticentromere antibody, one had anti-Ro antibody, one had anti-Scl-70 antibody, one had anti-dsDNA antibody, and eight patients were negative. The two patients who had anticentromere and anti-Scl-70 antibodies had also Sjögren’s syndrome and scleroderma diagnosis, respectively. Discussion. The prevalence of ANA in patients with sarcoidosis was found to be significantly higher than healthy control group and lower than RA patients. This result shows that ANA may have an important role in the pathogenesis of sarcoidosis and also could be important in revealing the overlap syndromes of sarcoidosis-connective tissue diseases. Further studies with larger series are necessary in this subject.

  1. Cardiac Sarcoidosis: Sorting Fact from Fiction in This Rare Cardiomyopathy

    Directory of Open Access Journals (Sweden)

    Indranee Rajapreyar, MD

    2015-10-01

    Full Text Available Sarcoidosis is a rare condition of granulomatous infiltration of many tissues of the body, including the heart. Cardiac sarcoidosis has been challenging to study, as it is often asymptomatic, although the initial presentation can be sudden cardiac death. The incidence and prevalence rates have been difficult to establish and no expert agreed upon guidelines for diagnosis and management of cardiac sarcoidosis exist, and clinical manifestations are varied. The pathophysiology of granuloma formation in the myocardium as well as other tissues is governed by immune response to some environmental antigen. Genetics is also thought to play a role, although gene alterations have not been extensively studied, and no specific set of genetic mutations has been identified to aid in identification of individuals at risk of developing disease. Epigenetic factors likely play a significant role in modulation of gene expression with respect to immune response. There is no standardized screening tool for the identification of cardiac sarcoidosis. The presence of systemic sarcoidosis and new-onset third-degree heart block or ventricular arrhythmias warrants further investigation for cardiac sarcoidosis. MRI and PET are useful in helping to identify cardiac sarcoidosis but are not stand-alone tests. Endomyocardial biopsy is the gold standard but has a low yield owing to the patchy nature of granuloma formation in the myocardium. Therapy should be instituted early and involves immunosuppressive therapy with predominant use of corticosteroids. Arrhythmias, either ventricular or high-grade heart blocks, are managed with device therapy. Clinical presentation may warrant use of antiarrhythmic agents and/or catheter ablation. Survival and disease prognosis are dependent on early diagnosis and treatment. This review details the current understanding of cardiac sarcoidosis and highlights diagnostic strategies and treatment with the aim of guiding the clinician to early

    2015-01-01

    BACKGROUND: The clinical presentation and outcome of sarcoidosis varies by race. However, the race difference in mortality outcome remains largely unknown. METHODS: We studied mortality related to sarcoidosis from 1999 through 2010 by examining data on multiple causes of death from the National Center for Health Statistics. We compared the comorbid conditions between sarcoidosis-related deaths with deaths caused by car accidents (previously healthy control subjects) and rheumatoid arthritis (chronic disease control subjects) in both African Americans and Caucasians. RESULTS: From 1999 through 2010, sarcoidosis was reported as an immediate cause of death in 10,348 people in the United States with a combined overall mean age-adjusted mortality rate of 2.8 per 1 million person-years. Of these, 6,285 were African American and 3,984 Caucasian. The age-adjusted mortality rate for African Americans was 12 times higher than for Caucasians. African Americans died at an earlier age than Caucasians. African Americans living in the District of Columbia and North Carolina and Caucasians living in Vermont had higher mortality rates. Although the total sarcoidosis age-adjusted mortality rate had not changed over the 12 year period studied, this rate increased for Caucasians (R = 0.747, P = .005) but not for African Americans. Compared with the control groups, pulmonary hypertension was significantly more common in individuals with sarcoidosis. CONCLUSIONS: This nationwide population-based study exposes a significant difference in ethnicity and sex among people dying of sarcoidosis in the United States. Pulmonary hypertension investigation should be considered in all patients with sarcoidosis, especially African Americans. PMID:25188873

    2012-04-01

    Full Text Available Abstract Background Sarcoidosis is a granulomatous disease characterized by a seemingly exaggerated immune response against a difficult to discern antigen. Dendritic cells (DCs are pivotal antigen presenting cells thought to play an important role in the pathogenesis. Paradoxically, decreased DC immune reactivity was reported in blood samples from pulmonary sarcoidosis patients. However, functional data on lung DCs in sarcoidosis are lacking. We hypothesized that at the site of disease DCs are mature, immunocompetent and involved in granuloma formation. Methods We analyzed myeloid DCs (mDCs and plasmacytoid DCs (pDCs in broncho-alveolar lavage (BAL and blood from newly diagnosed, untreated pulmonary sarcoidosis patients and healthy controls using 9-color flowcytometry. DCs, isolated from BAL using flowcytometric sorting (mDCs or cultured from monocytes (mo-DCs, were functionally assessed in a mixed leukocyte reaction with naïve allogeneic CD4+ T cells. Using Immunohistochemistry, location and activation status of CD11c+DCs was assessed in mucosal airway biopsies. Results mDCs in BAL, but not in blood, from sarcoidosis patients were increased in number when compared with mDCs from healthy controls. mDCs purified from BAL of sarcoidosis patients induced T cell proliferation and differentiation and did not show diminished immune reactivity. Mo-DCs from patients induced increased TNFα release in co-cultures with naïve allogeneic CD4+ T cells. Finally, immunohistochemical analyses revealed increased numbers of mature CD86+ DCs in granuloma-containing airway mucosal biopsies from sarcoidosis patients. Conclusion Taken together, these finding implicate increased local DC activation in granuloma formation or maintenance in pulmonary sarcoidosis.

    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 ...

    Measuring corneal biomechanical properties may help detect keratoconus suspect corneas and eliminate the risk of ectasia after LASIK. Data of 504 eyes separated into three groups were retrospectively reviewed: normal (n = 252), keratoconus suspect (n = 80), and keratoconus (n = 172). Corneal hysteresis (CH) and corneal resistance factor (CRF) were measured with an ocular biomechanics analyzer. Mean corneal hysteresis was 10.6 +/- 1.4 (SD) mm Hg in the normal group, compared with 10.0 +/- 1.6 mm Hg in the keratoconus suspect group and 8.1 +/- 1.4 mm Hg in the keratoconus group. The mean CRF was 10.6 +/- 1.6 mm Hg in the normal group compared with 9.7 +/- 1.7 in the keratoconus suspect group and 7.1 +/- 1.6 mm Hg in the keratoconus group. Mean CH and CRF were significantly different between the three groups (P corneas. Analyzing signal curves obtained with the biomechanics analyzer may provide additional valuable information for selecting qualified patients for refractive surgery.

    A 49-year-old man with cardiac sarcoidosis is presented. He suffered from congestive heart failure, and left ventricular asynergy and reduced function was evident by echocardiogram and left ventriculogram. A light microscopic examination of the endomyocardial biopsy revealed nonspecific myocarditis without giant cells or noncaseating granulomas. Under an electron microscope, however, several epithelioid cells were found in the specimen. The serum level of lysozyme was elevated. The patient had a past history of sarcoidosis of the eyes and lungs 22 years previously. Cardiac diseases presenting epithelioid cells other than sarcoidosis were clinically ruled out. Thus, the diagnosis of cardiac sarcoidosis was made based on both clinical and ultrastructural findings, and corticosteroid therapy was initiated. In the second biopsy, performed 4 months later, a noncaseating granuloma was found. Generally, the incidence of histological diagnosis of cardiac sarcoidosis by light microscopy is relatively low in endomyocardial biopsy specimens. The present case suggests that the addition of an ultrastructural examination may improve the diagnostic usefulness of the endomyocardial biopsy in cardiac sarcoidosis, since electron microscopy can clearly identify the presence of even one epithelioid cell.

    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.

    Conclusion: Co-existence of sarcoidosis, CD and APS is extremely rare. APS should be recognized as an accompanying disorder of sarcoidosis and antiphospholipids measured especially when there is a history of thrombosis or miscarriages. CD should not be overlooked in association to sarcoidosis, given the shared immunological and genetic background, even in the absence of a typical presentation of the disease.

    The association between sarcoidosis and autoimmune comorbidities has been reported, however, it has seldom been confirmed by a large nationwide study. Our study aimed to clarify the association between sarcoidosis and autoimmune comorbidities in the Taiwanese. A total of 1237 patients with sarcoidosis and 4948 age- and sex-matched control subjects were selected from the National Health Insurance Research Database of Taiwan from 1997 to 2010. Multiple logistic regressions were performed to calculate the odds of comorbidities between the two groups. The prevalence of sarcoidosis was 2.17/100 000 individuals in Taiwan. Sarcoidosis patients tended to run a higher risk of autoimmune comorbidities than the control group (17.6% vs 9.4%, P sarcoidosis. The sex-stratified analyses were carried out to demonstrate a significant association of sarcoidosis with ankylosing spondylitis in both sexes, but with autoimmune thyroid disease in male patients and with Sjögren's syndrome female patients, respectively. Besides, the diagnosis of the autoimmune comorbidities strongly associated with sarcoidosis tended to be established after that of sarcoidosis. This study demonstrated that patients with sarcoidosis tended to have autoimmune thyroid disease, Sjögren's syndrome and ankylosing spondylitis, and the diagnosis of sarcoidosis usually preceded that of associated comorbidities. Clinicians should be alert to autoimmune comorbidities in patients with sarcoidosis. © 2016 Japanese Dermatological Association.

    Sarcoidosis is a granulomatous disorder of unknown etiology. Infection, genetic factors, autoimmunity and an aberrant innate immune system have been explored as potential causes of sarcoidosis. The etiology of sarcoidosis remains unknown, and it is thought that it might be caused by an infectious agent in a genetically predisposed, susceptible host. Inflammation results from recognition of evolutionarily conserved structures of pathogens (Pathogen-associated molecular patterns, PAMPs) and/or from reaction to tissue damage associated patterns (DAMPs) through recognition by a limited number of germ line-encoded pattern recognition receptors (PRRs). Due to the similar clinical and histopathological picture of sarcoidosis and tuberculosis, Mycobacterium tuberculosis antigens such early secreted antigen (ESAT-6), heat shock proteins (Mtb-HSP), catalase-peroxidase (katG) enzyme and superoxide dismutase A peptide (sodA) have been often considered as factors in the etiopathogenesis of sarcoidosis. Potential non-TB-associated PAMPs include lipopolysaccharide (LPS) from the outer membrane of Gram-negative bacteria, peptidoglycan, lipoteichoic acid, bacterial DNA, viral DNA/RNA, chitin, flagellin, leucine-rich repeats (LRR), mannans in the yeast cell wall, and microbial HSPs. Furthermore, exogenous non-organic antigens such as metals, silica, pigments with/without aluminum in tattoos, pesticides, and pollen have been evoked as potential causes of sarcoidosis. Exposure of the airways to diverse infectious and non-infectious agents may be important in the pathogenesis of sarcoidosis. The current review provides and update on the role of PPRs and DAMPs in the pathogenesis of sarcoidsis. Copyright © 2017 Elsevier B.V. All rights reserved.

    The chronic granulomatous inflammation of sarcoidosis has been hypothesized to depend on the CD4+ T-helper lymphocyte. HIV infection, which depletes these cells, has been reported to attenuate the manifestations of sarcoidosis. We asked whether the development of symptomatic sarcoidosis in the context of preexisting HIV infection was dependent on the CD4+ lymphocyte count. We performed a retrospective standardized chart review of all patients who developed granulomatous inflammation following HIV infection at an urban academic referral center. We identified seven patients with sarcoidosis within this cohort and compared their CD4+ lymphocyte count to that in a cohort of 16 patients in whom similar granulomatous inflammation was found but who did not have sarcoidosis. We then compared our cases to all reported cases using a systematic literature review. The CD4+ lymphocyte count was > 200 cells/ microL in all of our patients with HIV infection when they developed subsequent sarcoidosis. In contrast, specific etiologies for granulomatous inflammation were found in all 10 HIV-infected patients who presented with granulomatous inflammation and a CD4+ lymphocyte count of 200 cells/ microL. We conclude that the development of the chronic granulomatous inflammation of sarcoidosis appears to depend on the preservation or restoration of the peripheral CD4+ lymphocyte count and that in most cases the CD4+ lymphocyte count exceeds 200 cells/ microL. Furthermore, alternative specific etiologies of granulomatous inflammation are generally identifiable in HIV-infected patients with peripheral CD4+ lymphocyte counts of < 200 cells/ microL.

  17. Copy number variation of FCGR genes in etiopathogenesis of sarcoidosis.

    Directory of Open Access Journals (Sweden)

    Marlena Typiak

    Full Text Available We have previously revealed that, in contrast to polymorphism of FCGR2B and FCGR3B, polymorphism of FCGR2A, FCGR2C and FCGR3A genes, encoding receptors for Fc fragment of immunoglobulin G (Fcγ receptors, play a role in increased level of circulating immune complexes with occurrence of Mycobacterium tuberculosis heat shock proteins in patients with sarcoidosis. However, this immunocomplexemia might also be caused by decreased clearance by immune cells due to a changed copy number of FCGR genes. Thus, the next step of our study was to evaluate copy number variation of FCGR2A, FCGR2B, FCGR2C, FCGR3A and FCGR3B in this disease. The analysis was carried out by real-time quantitative PCR on 104 patients and 110 healthy volunteers. Despite previously detected variation in allele/genotype frequencies of FCGR in sarcoidosis and its particular stages, there was no copy number variation of the tested genes between sarcoidosis or its stages and healthy control, as well as between stages themselves. A relevant increase in copy number of FCGR2C and FCGR3B in Stage IV of sarcoidosis vs. other stages and controls was detected, but this observation was based on a limited number of Stage IV patients. Hence, polymorphism of FCGR genes seems to be more important than their copy number variation in etiopathogenesis of sarcoidosis in patients from the Polish population.

    Sarcoidosis is known to be involved in diseases with vasculitis as sarcoid vasculitis. However, vasculitis in cutaneous sarcoidal lesions is extremely rare. Here we describe a case of sarcoidosis with multiple annular skin lesions with granulomatous vasculitis. A 62-year-old female was diagnosed with sarcoidosis by chest-abdominal computed tomographic examination and laboratory tests. The skin lesions had appeared on her lower limbs 2 years before. Physical examination showed multiple infiltrated annular eruptions on the lower extremities. A skin biopsy of an area of erythema showed multiple non-caseating epithelioid cell granulomas in the dermis and subcutaneous fat and granulomatous vasculitis with fibrinoid degeneration in the subcutaneous fat. There are two types of vasculitis in sarcoidosis: leukocytoclastic and granulomatous vasculitis. Ulcers and livedo were more common in granulomatous vasculitis than in leukocytoclastic vasculitis. The present case had unique annular skin lesions of sarcoidosis with granulomatous vasculitis. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Abstract Background Sarcoidosis is a multisystem disease of unknown origin characterized by the formation of noncaseating granulomas, in particular in the lungs, lymph nodes, eyes, and skin. Systemic treatment for cutaneous sarcoidosis can be used for large disfiguring lesions, generalized involvement, or recalcitrant lesions that did not respond to topical therapy. Case presentations We report three patients with recalcitrant cutaneous sarcoidosis who were treated with oral fumaric acid esters (FAE. Three female patients presented with cutaneous sarcoidosis that have proved to be refractory to various therapies, including corticosteroids and chloroquine. We treated the patients with FAE in tablet form using two formulations differing in strength (Fumaderm® initial, Fumaderm®. Dosage of FAE was performed according to the standard therapy regimen for psoriasis patients. After treatment with FAE (4–12 months, a complete clearance of skin lesions was achieved in the three patients. The side effects observed in this trial correspond to the well-known spectrum of adverse effects of FAE (flush, minor gastrointestinal complaints, lymphopenia. Conclusions On the basis of our findings FAE therapy seems to be a safe and effective regimen for patients with recalcitrant cutaneous sarcoidosis. Nevertheless further investigations are necessary to confirm our preliminary results.

    Sarcoidosis and idiopathic pulmonary fibrosis (IPF) are two common forms of interstitial lung disease. Fatigue is a recognised feature of sarcoidosis but an association between IPF and fatigue has not been investigated. To investigate the frequency and severity of fatigue in these groups, and variables affecting fatigue scores. A cross-sectional questionnaire study of patients with sarcoidosis and IPF followed-up at a single hospital was undertaken. Questionnaire data included validated measures of fatigue, anxiety, depression, sleepiness and dyspnoea, plus measures of disease severity including spirometry data. Questionnaires were administered to 232 patients (82 healthy volunteers, 73 sarcoidosis patients and 77 IPF patients). Sarcoidosis patients had statistically higher sleepiness scores but no significant difference was seen between overall measures of fatigue, anxiety or depression. Stratification by severity revealed a non-statistically significant tendency towards more severe fatigue scores in sarcoidosis. Regression analysis failed to identify any significant predictor variables measured in the sarcoidosis cohort, though in the IPF group both dyspnoea and sleepiness scores were significant predictors of fatigue (R2=0.74). Both sarcoidosis and IPF patients suffer with fatigue, although sarcoidosis patients tended towards reporting more severe fatigue scores, suggesting a subgroup with severe fatigue. The fatigue experienced by the two groups appears to be different; sarcoidosis patients report greater frequency of mental fatigue whereas IPF patients appear to suffer exhaustion, potentially related to dyspnoea. Dyspnoea and sleepiness scores modeled the majority of fatigue in the IPF group, whereas no single factor was able to predict fatigue in sarcoidosis.

    Sarcoidosis is a multisystemic immune disorder of unknown cause characterized by the formation of epithelioid granuloma in involved organs particularly the lung and the lymphatic system. Consistent recent advances have been made on the clinical, therapeutical and pathogenetic aspects. Various clinical phenotypes are better characterized and efforts to grade the severity could facilitate genetic studies and therapeutic trials. Pulmonary hypertension and some infrequent or atypical pulmonary manifestations as well as some rare extrapulmonary localizations have been thoroughly studied. Sarcoidosis-like granulomatosis due to identified causes constitute interesting models and have to be differentiated from sarcoidosis. THERAPEUTICAL ASPECTS: Anti-TNFalpha drugs have been investigated and infliximab has been proved efficient even though some limits to its efficiency have to be taken into account. PATHOGENETIC ASPECTS: Finally, advances concerning the pathogenesis, particularly genetic predisposing factors and phenotype/genotype correlations have been made.

    Full Text Available Even tiny despicable skin signs may eventually unveil systemic illnesses enabling a prompt start of medication and better prognosis. Here, we present a case of a 28-year-old female patient who came to the office complaining of a „minor irritation” on the left eyebrow that was a discrete and asymptomatic 5mm infiltrated apple jelly coloured papule that had started 6 months earlier. Biopsy of a second similar lesion discovered on left forearm showed granulomatous features of sarcoidosis. Under subsequent systemic investigation, the presence of sarcoidosis in other organs was found to be positive as stage II pulmonary sarcoidosis, and also with reticulo-endothelial involvement manifested by enlarged mediastinal lymph nodes. This case highlights the skin as a mirror to internal multisystemic disease and also the importance of investigating even small and discrete lesions with care and in depth.

    The diagnosis of cardiac sarcoidosis, particularly when there is no overt systemic involvement, is frequently delayed because of its varied manifestations. Focal left ventricular wall motion abnormalities were recognised in five patients with sarcoidosis. Three patients showed abnormal regional wall motion in the basal portion of the ventricular septum and free wall with sparing of the apex. The angiographic appearances supported the echocardiographic findings which were atypical of ischaemic heart disease. The remaining two patients both had diffuse left ventricular hypokinesia, with a focal abnormality that was most pronounced in the anteroapical region; this pattern is often seen with coronary disease. The recognition by echocardiography or angiography of focal abnormalities of wall motion affecting the basal portion of the ventricular septum should suggest the possibility of myocardial sarcoidosis even in the absence of recognised systemic manifestations.

    Familial Blau syndrome and sporadic early-onset sarcoidosis (EOS) are both systemic granulomatous diseases evoked by the spontaneous activation of mutated NOD2. In Japan, the R334W amino acid substitution is more frequently identified, whereas the R334Q mutation is rare and, in contrast to western countries where disease causing mutations are typically hereditary, most Japanese cases derive from sporadic mutations. Recently, a case with a six-base deletion in the NOD2 gene was reported. This Blau syndrome/EOS patient presented with the unpainful soft swelling of the dorsal side of the wrist and ankles, as well as flexion contracture at the proximal interphalangeal joint that gradually appeared during their clinical course. These features are useful for the differential diagnosis of Blau syndrome/EOS from juvenile idiopathic arthritis. Owing to their characteristic clinical symptoms, Blau and EOS patients can be identified earlier if medical experts become more acquainted with these distinctions. Even though specific treatment based on pathophysiologic mechanism has not been explored yet, early diagnosis will prevent the progression to severe impairment, which can severely affect patients' lives.

    Sarcoidosis is characterized by the appearance of noncausating, epitheloid cell granulomas, primarily in skin and lung. Hereditary disposition is well known; additional infection-associated triggers play a role for the development of inflammation mediated by T helper (Th)1 cells. Clinically, various disease courses can be observed that are characterized by the formation of skin papules at typical sites of the body which differ in their tendency to be associated with systemic organ involvement. Systemic disease without skin affections is also possible. The diagnosis is based on the typical clinical appearance, biopsy of affected tissue (e.g. skin, lung) and laboratory investigations. Additional systemic involvement needs to be excluded. In most cases, the disease is self-limited, but can also be life threatening due to organ fibrosis. The degree of (extra-)cutaneous involvement and level of discomfort are used to select the type of treatment, which ranges from topical immune suppressive agents to systemic therapy with corticosteroids. In nonresponders, additional modern immunosuppressive/immunomodulating therapeutic options are available.

    This study was undertaken to assess whether {sup 123}I-MIBG scintigraphy is useful to detect cardiac involvements of sarcoidosis. In 45 patients with sarcoidosis, dual SPECT with {sup 123}I-MIBG and {sup 201}Tl-Cl(Tl) were performed, and the findings were compared with electrocardiogram (ECG), 24 hour Holter ECG and ultrasound echocardiography. In order to evaluate cardiac involvements, Tl and MIBG extent score (E.S.) and severity score (S.S.) were calculated by a Bull`s eye map in addition to visual evaluation. Abnormal findings were recognized in 8.9% of all subjects in echocardiography, in 22.2% of those in ECG and Holter ECG, in 40% of those in Tl scintigraphy, and in 64.4% of those in MIBG scintigraphy. All of the Tl and MIBG abnormalities were detected in left ventricles, especially at the basal septal wall. At the inferior wall, abnormalities were observed more frequently by MIBG than by Tl. Tl E.S., Tl S.S. and MIBG E.S. were significantly higher in 10 patients with abnormal ECG findings than in 35 patients with normal ECG findings. Also, all of 10 patients with abnormal ECG findings had abnormal MIBG image, but 3 of them showed normal Tl images. 11 of 35 patients with normal ECG findings showed abnormal Tl and MIBG images (group A), 8 of 35 patients showed normal Tl images and abnormal MIBG images (group B), and 16 of 35 patients showed normal Tl and MIBG images (group C). MIBG S.S. of group A (11.3{+-}7.8) was significantly higher than that of group B (5.3{+-}3.1) or group C (2.6{+-}3.2). Furthermore, in group A, MIBG S.S. was significantly higher than Tl S.S. (5.5{+-}2.8). In a case of normal ECG with abnormal MIBG images, we seriously suspect cardiac involvements and recommend repeated Holter ECG tests as necessary in order to detect critical arrythmia. MIBG scintigraphy appeared to be a sensitive and useful method for the early detection of cardiac sarcoidosis. (J.P.N.)

    Sarcoidosis is a granulomatous multisystemic disorder that rarely involves subcutaneous tissue. We describe the MR imaging findings of a subcutaneous sarcoidosis in a patient that presented with a nontender, palpable soft tissue mass on the left buttock, which was confirmed after surgical excision. The MR images showed the presence of a subcutaneous mass that breached the adjacent fascia with an irregular outline and homogeneous, slightly higher signal intensity than the surrounding muscle as seen on a T2-weighted image and with homogeneous enhancement after contrast injection. The lesion could not be differentiated from a sarcoma or a malignancy.

    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.

    The purpose of this study was to compare combined PET/MRI with PET/CT and cardiac MRI in the evaluation of cardiac sarcoidosis and myocarditis. Ten patients (4 men and 6 women; 56.1 ± 9.6 years old) were prospectively enrolled for evaluation of suspected cardiac sarcoidosis or myocarditis. Written informed consent was obtained. Following administration of 9.9 ± 0.9 mCi F-FDG, patients underwent standard cardiac PET/CT followed by combined PET/MRI using a simultaneous 3-T scanner. Cardiac MRI sequences included ECG-triggered cine SSFP, T2-weighted, and late gadolinium-enhanced imaging. Myocardial involvement was assessed with separate analysis of combined PET/MRI, PET/CT, and cardiac MRI data using dedicated postprocessing software. Estimates of radiation dose were derived from the applied doses of F-FDG and CT protocol parameters. Imaging was acquired with a delay from F-FDG injection of 90.2 ± 27.4 minutes for PET/CT and 207.7 ± 40.3 minutes for PET/MRI. Total scan time for PET/MRI was significantly longer than for PET/CT (81.4 ± 14.8 vs 12.0 minutes, P PET/MRI compared with PET/CT (6.9 ± 0.6 vs 8.2 ± 1.1 mSv, P = 0.007). There was no significant difference in the number of positive cases identified between combined PET/MRI (n = 10 [100%]), PET/CT (n = 6 [60%]), and cardiac MRI (n = 8 [80%]), P = 0.091. Simultaneous cardiac PET/MRI is feasible in the evaluation of cardiac sarcoidosis and myocarditis achieving diagnostic image quality.

    Blau syndrome/early-onset sarcoidosis (Blau/EOS) is an autoinflammatory disease characterized by granulomatous arthritis, uveitis, and skin rash. It has been shown that gain-of-function NOD2 mutations cause Blau/EOS. In this paper, we describe a patient with a gain-of-function NOD2 mutation who developed infantile Takayasu arteritis, which is rare in Blau/EOS, but who has not yet had significant granulomatous changes in joints, eyes, or skin. We suspect that this case is an unusual phenotype of Blau/EOS.

    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 normaln 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. PMID:26834928

    Full Text Available Sarcoidosis is a multisystem granulomatous disorder of unknown etiology and it may rarely be associated with a second disorder. Celiac disease is an immune-mediated enteropathy characterized with malabsorption caused by gluten intolerance, and several reports indicate an association between celiac disease and sarcoidosis. In addition, although celiac disease is associated with several extraintestinal pathologies, venous thrombosis has been rarely reported. Herein we present a rare case report of a patient with a diagnosis of sarcoidosis, celiac disease and deep venous thrombosis because of the rare association of these disorders. The patient was admitted with abdominal pain, weight loss, chronic diarrhea and a 5-day history of swelling in her right leg. A diagnosis of deep venous thrombosis was achieved by doppler ultrasonographic examination. The diagnosis of celiac disease was made by biopsy of duodenal mucosa and supported with elevated serum level of anti-gliadin IgA and IgG, and a diagnosis of sarcoidosis was achieved by transbronchial needle aspiration from the subcarinal lymph node during flexible bronchoscopy.

    Sarcoidosis is a granulomatous multisystem disorder of unclear etiology that involves any organ, most commonly the lung and the lymph nodes. It is hypothesized that the disease derives from the interaction between single or multiple environmental factors and genetically determined host factors. Multiple potential etiologic agents for sarcoidosis have been proposed without any definitive demonstration of causality.We report the case of two patients, husband (57 years old) and wife (55 years old), both suffering from sarcoidosis. They underwent a lymph node biopsy by mediastinoscopy which showed a "granulomatous epithelioid giant cell non-necrotising chronic lymphadenitis". They had lived up to 3 years ago in the country in a farm, in contact with organic dusts, animals such as dogs, chickens, rabbits, pigeons; now they have lived since about 3 years in an urban area where there are numerous chemical industries and stone quarries. The aim of this case report was to focus on environmental factors that might be related to the pathogenesis of the sarcoidosis.

  1. Assessment of Cardiac Sarcoidosis with Advanced Imaging Modalities

    Akasaka, Takashi

    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

    2016-08-01

    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.

    Full Text Available Literature on concurrent association of sarcoidosis with lymphoproliferative malignancies other than lymphoma e.g. multiple myeloma is meager. 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.

    Full Text Available Autoimmune endocrinopathies and, less commonly, thyroid autoimmune disease have been reported in patients with sarcoidosis. Similarities exist in the pathogenesis of these two conditions. Concomitant sarcoidosis in the thyroid gland in patients with Graves′ disease may contribute to the resistance to antithyroid drugs and radioiodine therapy. We present the clinical, laboratory, imaging, and pathologic findings of a patient with Graves′ disease who was unresponsive to medical management. This 37-year-old man presented with thyrotoxicosis. Thyroid hormone assays and 99m Technitium findings were consistent with Graves′ disease. He was also found to have hilar lymphadenopathy. Patient failed to achieve remission with high doses of antithyroid drugs and 2 sessions of radioiodine ablative therapy.Histopathology of lymph nodesdisclosed noncaseating granulomas, consistent with sarcoidosis. Patient′s thyrotoxicosis subsided only following steroid administration. The histopathology of the thyroid gland on aspiration and the subsidence of symptoms with steroids reiterate the possibility of thyroid sarcoidosis. This diagnosis needs biopsy for confirmation, which our patient didn′t consent for.

    The aim of this case-control study was to investigate the prevalence of exercise intolerance, muscle weakness and fatigue in sarcoidosis patients. Additionally, we evaluated whether fatigue can be explained by exercise capacity, muscle strength or other clinical characteristics (lung function tests, radiographic stages, prednisone usage and inflammatory markers). 124 sarcoidosis patients (80 males) referred to the Maastricht University Medical Centre (Maastricht, the Netherlands) were included (mean age 46.6±10.2 yrs). Patients performed a 6-min walk test (6MWT) and handgrip force (HGF), elbow flexor muscle strength (EFMS), quadriceps peak torque (QPT) and hamstring peak torque (HPT) tests. Maximal inspiratory pressure (P(I,max)) was recorded. All patients completed the Fatigue Assessment Scale (FAS) questionnaire. The 6MWT was reduced in 45% of the population, while HGF, EFMS, QPT and HPT muscle strength were reduced in 15, 12, 27 and 18%, respectively. P(I,max) was reduced in 43% of the population. The majority of the patients (81%) reported fatigue (FAS ≥22). Patients with reduced peripheral muscle strength of the upper and/or lower extremities were more fatigued and demonstrated impaired lung functions, fat-free mass, P(I,max), 6MWT and quality of life. Fatigue was neither predicted by exercise capacity, nor by muscle strength. Besides fatigue, exercise intolerance and muscle weakness are frequent problems in sarcoidosis. We therefore recommend physical tests in the multidisciplinary management of sarcoidosis patients, even in nonfatigued patients.

    Rationale: Genetic variation plays a significant role in the etiology of sarcoidosis. However, only a small fraction of its heritability has been explained so far. Objectives: To define further genetic risk loci for sarcoidosis, we used the Immunochip for a candidate gene association study of immune-associated loci. Methods: Altogether the study population comprised over 19,000 individuals. In a two-stage design, 1,726 German sarcoidosis cases and 5,482 control subjects were genotyped for 128,705 single-nucleotide polymorphisms using the Illumina Immunochip for the screening step. The remaining 3,955 cases, 7,514 control subjects, and 684 parents of affected offspring were used for validation and replication of 44 candidate and two established risk single-nucleotide polymorphisms. Measurements and Main Results: Four novel susceptibility loci were identified with genome-wide significance in the European case-control populations, located on chromosomes 12q24.12 (rs653178; ATXN2/SH2B3), 5q33.3 (rs4921492; IL12B), 4q24 (rs223498; MANBA/NFKB1), and 2q33.2 (rs6748088; FAM117B). We further defined three independent association signals in the HLA region with genome-wide significance, peaking in the BTNL2 promoter region (rs5007259), at HLA-B (rs4143332/HLA-B*0801) and at HLA-DPB1 (rs9277542), and found another novel independent signal near IL23R (rs12069782) on chromosome 1p31.3. Conclusions: Functional predictions and protein network analyses suggest a prominent role of the drug-targetable IL23/Th17 signaling pathway in the genetic etiology of sarcoidosis. Our findings reveal a substantial genetic overlap of sarcoidosis with diverse immune-mediated inflammatory disorders, which could be of relevance for the clinical application of modern therapeutics PMID:26051272

    Full Text Available Aim: To review a general hospital′s experience with sarcoidosis and the clinical pattern of the disease among Saudis. Methods: A retrospective file review was carried out on all patients with a proven diagnosis of sarcoidosis in a general hospital in Eastern Saudi Arabia over a period of 11 years (1998-2008. Results: Sixty-nine patients, of whom 33 cases were included in the analyses, were diagnosed to have sarcoidosis during the study period. There were 18 females and 15 males. The mean age was 44.5 years (SD 17. The most common presentations were cough (48%, dyspnea (21%, joint pain (18%, splenomegaly (12%, hepatomegaly (9%, and lymphadenopathy (5%. The biochemical analysis showed elevated calcium levels in 6% and elevated angiotensin converting enzyme (ACE in 14 (46.7%. The tuberculin skin test was negative in all tested patients (n = 29 except one patient. The patients were classified using the modified Scadding classification system. None of the patients was in stage 0, 39.4% were in stage 1, 45% were in stage 2 and 15% were in stage 3.. The diagnosis in all patients was proven histologically. The outcome was favorable in most patients (85%, and in 6% of the patients, the course was chronic and progressive, although 66% received active treatment. Conclusion: Sarcoidosis does occur in native Saudis. The clinical presentation of these patients was similar to the western pattern of disease with some differences such as relative lack of cardiac, eye, parotid, and central nervous system involvement. The rarity of cardiac and central nervous system involvement was comparable with other Middle Eastern studies. Sarcoidosis, though rare in our community, should still be considered in the differential diagnosis of patients with the typical presentation after excluding tuberculosis.

    Sarcoidosis is a granulomatous disease of unknown cause, which affects all systems, especially the lungs and the lymphatic system. Genetic and environmental factors are held accountable for the etiology. Based on the general opinion, sarcoidosis develops after exposure to a specific environmental agent by genetically susceptible individuals.  The present study aimed to evaluate the disease susceptibility of the GSTT1 and GSTM1 gene polymorphisms in the patients with sarcoidosis. The present study included 78 patients; 38 patients with histopathologically verified sarcoidosis and 40 control subjects. Multiplex PCR method was used to determine the GSTT1 and GSTM1 gene polymorphisms. The genotype was determined based on the bands formed in the agarose gel electrophoresis. The statistical analysis was done using the chi-square test. The positive/negative genotype rates were 79%/21% and 53%/47%, respectively in the case group for the GSTT1 and GSTM1 gene polymorphisms, whereas the positive/negative genotype rates were 77%/23% and 55%/45% in the control group. There was no statistically significant difference in the positive and negative genotypes compared with the case group and the control group for the GSTT1 and GSTM1 gene polymorphisms (p > 0.05). The results from the present study suggest that there is not any association with the control group for the disease susceptibility of the GSTT1 and GSTM1 gene polymorphisms in patients with sarcoidosis, and this result should be supported by large-scale studies because of the limited number of cases in the present study.

    Sarcoidosis is a systemic disease of unknown cause characterized by the formation of immune granulomas which most often involve the lung and the lymphatic system. Sarcoidosis may encompass numerous different clinical presentations. Typical presentations often prompt a rapid diagnosis while in 25 to 50% of cases, diverse and less typical presentations may lead to delayed diagnosis. The mediastinopulmonary sphere is involved in 85 to 95% of cases, associated with extrapulmonary localizations in half of cases while extrapulmonary localizations without lung involvement may be seen in 5 to 15% of cases. Bilateral hilar lymphadenopathy is the most typical sign at chest radiography. Computed tomography (CT) is essential face for atypical manifestations of the disease to avoid confusion with differential diagnoses and, sometimes, comorbidities. CT typically evidences diffuse pulmonary perilymphatic micronodules, with a perilobular and fissural distribution and upper and posterior predominance, even when an atypical CT pattern is predominant. CT allows deciphering pulmonary lesions in cases of pulmonary fibrosis, pulmonary hypertension, and airflow limitation. Pulmonary function tests generally correlate with the overall disease process. Forced vital capacity is the simplest and most accurate parameter to reflect the impact of pulmonary sarcoidosis. Cardiopulmonary exercise testing helps in understanding the mechanism behind dyspnea of uncertain origin. Endoscopic transbronchial needle aspiration is an extra tool to support diagnosis in addition to more classical biopsy means. Bronchoalveolar lavage (BAL) may be used for individual patients while it is not really decisive for the diagnosis of sarcoidosis for most patients. Diagnosis relies on compatible clinical and radiological presentation, evidence of noncaseating granulomas and exclusion of other diseases with a similar presentation or histology. The probability of diagnosis at presentation is variable from case to case

    Differentiation between tuberculosis (TB) and sarcoidoisis is sometimes extremely difficult. Sequential occurrence of sarcoidosis and TB in the same patient is uncommon. We present the case of a young man, with a proven diagnosis of sarcoidosis who later developed TB after completion of treatment for sarcoidosis. A 32-year-old male patient presented with low-grade fever since two months. Physical examination revealed cervical lymphadenopathy. Initial fine needle aspiration cytology (FNAC) of the cervical lymph node was suggestive of granulomatous inflammation; the chest radiograph was normal. Repeat FNAC from the same lymph node was suggestive of reactive lymphoid hyperplasia. The patient was treated with antibiotics and followed-up. He again presented with persistence of fever and lymphadenopathy and blurring of vision. Ophthalmological examination revealed uveitis, possibly due to a granulomatous cause. His repeat Mantoux test again was non-reactive; serum angiotensin converting enzyme (ACE) levels were raised. This time an excision biopsy of the lymph node was done which revealed discrete, non-caseating, reticulin rich granulomatous inflammation suggestive of sarcoidosis. The patient was treated with oral prednisolone and imporved symptomatically. Subsequently, nearly nine months after completion of corticosteroid treatment, he presented with low-grade, intermittent fever and a lymph node enlargement in the right parotid region. FNAC from this lymph node showed caseating granulomatous inflammation and the stain for acid-fast bacilli was positive. He was treated with Category I DOTS under the Revised National Tuberculosis Control Programme and improved significantly. The present case highlights the need for further research into the aetiology of TB and sarcoidosis.

    Six cases of ocular injury following paintball injuries sustained during war games are described. A CO2-powered rifle shoots a 14 mm plastic-coated paintball at participants. The muzzle velocity of the gun is 250 ft/sec (76 m/sec). Locally manufactured paintballs are harder than the more expensive imported varieties and may account for the severity of our reported injuries. Six patients presented to a retinal specialist with various ocular injuries, predominantly of the posterior pole. All patients were young males. There were no cases of ocular penetration. A variety of retinal pathologies was noted, with three cases requiring surgery; however this did not significantly improve the visual outcome. These cases highlight the severe ocular injuries that may occur from paintball injuries. Recommendations to avoid ocular injury are made.

    Full Text Available Sarcoidosis, a systemic granulomatous syndrome invariably affecting the lung, typically spontaneously remits but in ~20% of cases progresses with severe lung dysfunction or cardiac and neurologic involvement (complicated sarcoidosis. Unfortunately, current biomarkers fail to distinguish patients with remitting (uncomplicated sarcoidosis from other fibrotic lung disorders, and fail to identify individuals at risk for complicated sarcoidosis. We utilized genome-wide peripheral blood gene expression analysis to identify a 20-gene sarcoidosis biomarker signature distinguishing sarcoidosis (n = 39 from healthy controls (n = 35, 86% classification accuracy and which served as a molecular signature for complicated sarcoidosis (n = 17. As aberrancies in T cell receptor (TCR signaling, JAK-STAT (JS signaling, and cytokine-cytokine receptor (CCR signaling are implicated in sarcoidosis pathogenesis, a 31-gene signature comprised of T cell signaling pathway genes associated with sarcoidosis (TCR/JS/CCR was compared to the unbiased 20-gene biomarker signature but proved inferior in prediction accuracy in distinguishing complicated from uncomplicated sarcoidosis. Additional validation strategies included significant association of single nucleotide polymorphisms (SNPs in signature genes with sarcoidosis susceptibility and severity (unbiased signature genes - CX3CR1, FKBP1A, NOG, RBM12B, SENS3, TSHZ2; T cell/JAK-STAT pathway genes such as AKT3, CBLB, DLG1, IFNG, IL2RA, IL7R, ITK, JUN, MALT1, NFATC2, PLCG1, SPRED1. In summary, this validated peripheral blood molecular gene signature appears to be a valuable biomarker in identifying cases with sarcoidoisis and predicting risk for complicated sarcoidosis.

    2013-01-01

    Background Extrapulmonary involvement by sarcoidosis is observed in about 30–40% of patients with sarcoidosis. Little is known about the frequency and clinical characteristics of sinonasal sarcoidosis. Methods We retrospectively analyzed 12 cases of biopsy-proven sinonasal sarcoidosis. Patients were identified from a patient population of 1360 patients with sarcoidosis at the Outpatient Clinic for Sarcoidosis and Rare Lung Diseases at LungClinic Grosshansdorf, a tertiary care hospital for respiratory medicine. Results The most frequent signs and symptoms were nasal polyps (4 cases), epistaxis (3 cases), nasal crusts (8 cases) and anosmia (5 cases). Pulmonary sarcoidosis of the patients was staged as stage I (n = 1) and stage II (n = 11) on chest radiographs. Spirometry was normal in 11 patients. 7 patients had a diffusion capacity of the lung for carbon monoxide of less than 90% of predicted. Other organs were affected in 8 patients. All patients received systemic corticosteroid treatment and most patients received topical steroids. 5 patients received steroid sparing agents. Repeated sinus surgery had to be performed in 4 patients. Conclusions Sinonasal involvement is a rare disease manifestation of sarcoidosis with a frequency slightly lower than 1% in our patient population. The clinical course of sinonasal sarcoidosis can be complicated by relapse despite systemic immunosuppressive treatment and repeated sinus surgery. PMID:24070015

    Sarcoidosis is a systemic disease characterized by the formation of granulomas in various organs, mainly lungs and lymphatic system. Joint, muscle, and bone involvement is also rather common. Recent studies on its pathogenesis and therapeutic management are reviewed here. The pathogenesis of sarcoidosis is not fully elucidated. An exaggerated granulomatous reaction after exposure to unidentified antigens in genetically susceptible individuals evokes a clinical situation which we call sarcoidosis. No firm guidelines exist on whether, when, and how treatment should be started. Treatment is dependent on the presentation and the distribution, extensiveness and severity of sarcoidosis. Treatment of Löfgren's triad-related symptoms starts with NSAIDs; in other more extensive manifestations of sarcoidosis, the initiating dosage of glucocorticosteroids is approximately 20 mg daily. In terms of evidence-based treatment for sarcoidosis, only a few randomized controlled trials have been done. There is no cure for chronic sarcoidosis, and treatment only changes the granulomatous process and its clinical consequences. Identified associations of certain polymorphisms with severity of the disease and treatment response suggest future research questions as well as finding the cause(s) of sarcoidosis, and the elucidation of relevant biomarkers and new efficient treatments. Between 20 and 70% of patients need systemic therapy. The increased awareness of long-term side-effects of glucocorticosteroids and the emergence of new drugs have changed the treatment of sarcoidosis. Alternative or additional options to corticosteroids should be assessed.

    Purpose To evaluate the subjective and objective measures of ocular surface disease in patients with glaucoma. Design Cross-sectional study. Participants Sixty-four glaucoma subjects with bilateral visual field (VF) loss and 59 glaucoma suspects with normal VFs. Methods Consecutive patients were recruited prospectively from the Wilmer Eye Institute Glaucoma Clinic. Main Outcome Measures Tear film breakup time (TBUT), corneal staining score (0–15), and Schirmer’s test results were included as objective metrics, whereas the Ocular Surface Disease Index (OSDI) questionnaire was administered to assess symptoms. Total OSDI score, vision-related subscore (derived from questions about vision and task performance), and discomfort-related subscore (derived from questions about ocular surface discomfort) were calculated for each subject. Results Seventy-five percent (48/64) of glaucoma subjects and 41% (24/59) of glaucoma suspects were receiving topical medications. The corneal staining grade was greater in glaucoma subjects than in glaucoma suspects (6.4 vs. 4.1; P0.20 for both). Multivariate regression models showed that topical glaucoma therapy burden was associated with a significantly higher total corneal staining grade (β, +0.9 for each additional glaucoma drop; 95% confidence interval [CI], 0.5–1.3; P0.20 for both). Glaucoma subjects had significantly higher total OSDI scores than glaucoma suspects (16.7 vs. 7.9; Pglaucoma group (11.1 vs. 3.3; Pglaucoma therapy burden was not associated with higher total OSDI score or vision- or discomfort-related subscore (P>0.20 for all). Conclusions Glaucoma is associated with significant ocular surface disease, and topical glaucoma therapy burden seems predictive of corneal staining severity. However, OSDI is a poor metric for capturing ocular surface disease in glaucoma because symptoms seem to be related largely to VF loss. PMID:23714318

    "Red eye" is used as a general term to describe irritated or bloodshot eyes. It is a recognizable sign of an acute/chronic, localized/systemic underlying inflammatory condition. Conjunctival injection is most commonly caused by dryness, allergy, visual fatigue, contact lens overwear, and local infections. In some instances, red eye can represent a true ocular emergency that should be treated by an ophthalmologist. A comprehensive assessment of red eye conditions is required to preserve the patients visual function. Severe ocular pain, significant photophobia, decreased vision, and history of ocular trauma are warning signs demanding immediate ophthalmological consultation. Copyright © 2017 Elsevier Inc.

    Ocular recognition is a new area of biometric investigation targeted at overcoming the limitations of iris recognition performance in the presence of non-ideal data. There are several advantages for increasing the area beyond the iris, yet there are also key issues that must be addressed such as size of the ocular region, factors affecting performance, and appropriate corpora to study these factors in isolation. In this paper, we explore and identify some of these issues with the goal of better defining parameters for ocular recognition. An empirical study is performed where iris recognition methods are contrasted with texture and point operators on existing iris and face datasets. The experimental results show a dramatic recognition performance gain when additional features are considered in the presence of poor quality iris data, offering strong evidence for extending interest beyond the iris. The experiments also highlight the need for the direct collection of additional ocular imagery.

  12. Ocular rosacea: a review

    Directory of Open Access Journals (Sweden)

    Ana Carolina Cabreira Vieira

    2012-10-01

    Full Text Available Rosacea is a prevalent chronic cutaneous disorder with variable presentation and severity. Although considered a skin disease, rosacea may evolve the eyes in 58-72% of the patients, causing eyelid and ocular surface inflammation. About one third of the patients develop potentially sight-threatening corneal involvement. Untreated rosacea may cause varying degrees of ocular morbidity. The importance of early diagnosis and adequate treatment cannot be overemphasized. There is not yet a diagnostic test for rosacea. The diagnosis of ocular rosacea relies on observation of clinical features, which can be challenging in up to 90% of patients in whom accompanying roseatic skin changes may be subtle or inexistent. In this review, we describe the pathophysiologic mechanisms proposed in the literature, clinical features, diagnosis and management of ocular rosacea, as well as discuss the need for a diagnostic test for the disease.

    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. (orig.)

    Early onset sarcoidosis is a granulomatous disease which is characterized by synovitis, polyarthritis, skin and eye involvement. We report the skeletal features of one patient with a family history and clinical symptoms suggestive of early onset sarcoidosis (EOS) which was confirmed by skin biopsy. Radiographs reveal postarthritic deformities of the MCP joints, contractures, a coarsened trabecular pattern at the PIP joints and small bone cysts resembling osteitis cystoides multiplex. Similar lesions were described in radiographs of the older sister and an uncle of our patient. This is the first report demonstrating bone cysts and erosions which could be a diagnostic feature in this rare disease and may help to differentiate other rheumatoid disorders. (orig.)

    2017-07-01

    Sarcoidosis is a systemic granulomatous disease of unknown aetiology, which is characterized by bilateral hilar lymphadenopathy and pulmonary disease. Clinically detected cardiac involvement occurs in 5% of sarcoid patients, although cardiac manifestations are discovered in 25% of the cases at autopsy. Sarcoid heart disease frequently causes atrioventricular block. The authors present the case of a 44-year-old man with bradycardia. On admission, second degree Mobitz II, then third degree atrioventricular block was diagnosed. Coronarography showed normal coronary arteries. 2.5 years following artificial Biotronik Entovis DR type pacemaker implantation, sudden cardiac death occurred. Autopsy revealed sarcoidosis with cardiac, pulmonary, splenic, renal and lymph node involvement. In case of young or middle-aged patients with atrioventricular block, it is best to search for other causes if the most common coronary origin can be excluded. Orv Hetil. 2017; 158(27): 1067-1070.

    The first manifestation of sarcoidosis is usually at the pulmonary level. The case is described of a 40-year-old female patient, who presented with an increased volume of the lacrimal gland and mechanical ptosis of upper left eyelid as the first expression of this disease. The diagnosis of systemic sarcoidosis with primary presentation of the lacrimal gland was made after performing several immunological studies with negative results, imaging studies, and taking of glandular and lymph node biopsies. A favourable response was achieved with oral methotrexate treatment. Copyright © 2017 Sociedad Española de Oftalmología. Publicado por Elsevier España, S.L.U. All rights reserved.

    Vertebral involvement in sarcoidosis is rare and its clinical and imaging features are non-specific. Indeed, because the lesions are hard to differentiate from metastatic disease based on imaging alone, a histological confirmation is advised. Fatty replacement is a well-known finding indicating stabilization and healing in both benign and malignant conditions. It can be used as an indicator of a favorable disease course and response to treatment. We report the case of a 43-year-old woman with multifocal vertebral sarcoidosis lesions and long-term follow-up showing progressive and gradual fatty involution on magnetic resonance imaging (MRI) during 4 years of steroid treatment with a final favorable outcome.

    Full Text Available Cranial palsies are a very rare feature of SLE. Similarly, peripheral sensory-motor axonal neuropathy is very uncommon in SLE. The combination of the two as the presenting symptoms of SLE is a diagnostic challenge particularly in an elderly male patient with a known diagnosis of sarcoidosis. This case serves to highlight the diagnostic considerations in such a patient. The lack of response to standard therapy and the presence of subtle clues like anemia, proteinuria, and mild serositis should prompt the physician to look for alternate diagnoses. The potential association of SLE and sarcoidosis is also discussed. SLE can be present in elderly male patients with cranial and peripheral neuropathy.

    2013-01-01

    Rationale Sarcoidosis is a granulomatous disease of unknown etiology. Many patients with sarcoidosis demonstrate antigen-specific immunity to mycobacterial virulence factors. Th-17 cells are crucial to the immune response in granulomatous inflammation, and have recently been shown to be present in greater numbers in the peripheral blood and bronchoalveolar lavage (BAL) fluid (BALF) of sarcoidosis patients than healthy controls. It is unclear whether Th-17 cells in sarcoidosis are specific for mycobacterial antigens, or whether they have similar functionality to control Th-17 cells. Methods Flow cytometry was used to determine the numbers of Th-17 cells present in the peripheral blood and BALF of patients with sarcoidosis, the percentage of Th-17 cells that were specific to the mycobacterial virulence factor ESAT-6, and as well as to assess IFN-γ expression in Th-17 cells following polyclonal stimulation. Results Patients with sarcoidosis had greater numbers of Th-17 cells in the peripheral blood and BALF than controls and produced significantly more extracellular IL-17A (p=0.03 and p=0.02, respectively). ESAT-6 specific Th-17 cells were present in both peripheral blood and BALF of sarcoidosis patients (psarcoidosis patients produced less IFN-γ than healthy controls. Conclusions Patients with sarcoidosis have mycobacterial antigen-specific Th-17 cells peripherally and in sites of active sarcoidosis involvement. Despite the Th1 immunophenotype of sarcoidosis immunology, the Th-17 cells have reduced IFN-γ expression, compared to healthy controls. This reduction in immunity may contribute to sarcoidosis pathogenesis. PMID:23073617

    Sarcoidosis is a multi-system inflammatory disorder characterized by the presence of non-caseating granulomas in involved organs. Patients with sarcoidosis have a reduced quality-of-life and are at an increased risk for several comorbidities. Little is known about the direct and indirect cost of sarcoidosis following the initial diagnosis. To provide an estimate of the healthcare resource utilization (HCRU) and costs borne by commercial payers for sarcoidosis patients in the US. Patients with a first diagnosis of sarcoidosis between January 1, 1998 and March 31, 2015 ("index date") were selected from a de-identified privately-insured administrative claims database. Sarcoidosis patients were required to have continuous health plan enrollment 12 months prior to and following their index dates. Propensity-score (1:1) matching of sarcoidosis patients with non-sarcoidosis controls was carried out based on a logistic regression of baseline characteristics. Burden of HCRU and work loss (disability days and medically-related absenteeism) were compared between the matched groups over the 12-month period following the index date ("outcome period"). A total of 7,119 sarcoidosis patients who met the selection criteria were matched with a control. Overall, commercial payers incurred $19,714 in mean total annual healthcare costs per sarcoidosis patient. The principle cost drivers were outpatient visits ($9,050 2015 USD, 46%) and inpatient admissions ($6,398, 32%). Relative to controls, sarcoidosis patients had $5,190 (36%) higher total healthcare costs ($19,714 vs $14,524; p economic burden to payers in the first year following diagnosis.

    Background and aim Sarcoidosis is a systemic granulomatous inflammatory disease whose causes are still unknown and for which epidemiological data are often discordant. The aim of our study is to investigate prevalence and spatial distribution of cases, and identify environmental exposures associated with sarcoidosis in an Italian province. Methods After georeferentiation of cases, the area under study was subdivided with respect to Municipality and Health Districts and to the altitude in order to identify zonal differences in prevalence. The bioaccumulation levels of 12 metals in lichen tissues were analyzed, in order to determine sources of air pollution. Finally, the analysis of the correlation between metals and between pickup stations was performed. Results 223 patients were identified (58.3% female and 41.7% male of total) and the mean age was 50.6±15.4 years (53.5±15.5 years for the females and 46.5±14.4 for the males). The mean prevalence was 49 per 100.000 individuals. However, we observed very heterogeneous prevalence in the area under study. The correlations among metals revealed different deposition patterns in lowland area respect to hilly and mountain areas. Conclusions The study highlights a high prevalence of sarcoidosis cases, characterized by a very inhomogeneous and patchy distribution with phenomena of local aggregation. Moreover, the bioaccumulation analysis was an effective method to identify the mineral particles that mostly contribute to air pollution in the different areas, but it was not sufficient to establish a clear correlation between the onset of sarcoidosis and environmental risk factors.

    2015-04-01

    Full Text Available Sarcoidosis is a granulomatous inflammatory disease, diagnosed through tissue biopsy of involved organs in the absence of other causes such as tuberculosis (TB. No specific serologic test is available to diagnose and differentiate sarcoidosis from TB. Using a high throughput method, we developed a T7 phage display cDNA library derived from mRNA isolated from bronchoalveolar lavage (BAL cells and leukocytes of sarcoidosis patients. This complex cDNA library was biopanned to obtain 1152 potential sarcoidosis antigens and a microarray was constructed to immunoscreen two different sets of sera from healthy controls and sarcoidosis. Meta-analysis identified 259 discriminating sarcoidosis antigens, and multivariate analysis identified 32 antigens with a sensitivity of 89% and a specificity of 83% to classify sarcoidosis from healthy controls. Additionally, interrogating the same microarray platform with sera from subjects with TB, we identified 50 clones that distinguish between TB, sarcoidosis and healthy controls. The top 10 sarcoidosis and TB specific clones were sequenced and homologies were searched in the public database revealing unique epitopes and mimotopes in each group. Here, we show for the first time that immunoscreenings of a library derived from sarcoidosis tissue differentiates between sarcoidosis and tuberculosis antigens. These novel biomarkers can improve diagnosis of sarcoidosis and TB, and may aid to develop or evaluate a TB vaccine.

  4. Biopsy proven pituitary sarcoidosis presenting as a possible adenoma.

    Sarcoidosis is a well-recognized systemic granulomatous process which involves the central nervous system in 5-15% of patients. One of the more frequent sites of central nervous system involvement is the pituitary and hypothalamic region. Involvement of the sellar region by sarcoidosis is overall an infrequent occurrence, comprising less than 1% of all intrasellar lesions. Patients typically present with an infiltrative lesion on imaging studies and clinically with symptoms related to diabetes insipidus or hyperprolactinemia. This report describes a 38-year-old woman who initially presented with a variety of symptoms including headaches, light sensitivity, nausea and vomiting, acute visual changes, cold intolerance, amenorrhea, decreased libido, fatigue and galactorrhea. She had an elevated serum prolactin level and evidence of oligoclonal bands in the cerebrospinal fluid. Imaging studies discovered a 1.8cm mass involving the pituitary gland and compressing the optic chiasm. The lesion was excised and microscopically was marked by a chronic inflammatory cell infiltrate and scattered nonnecrotizing granulomas. Stains and microbiologic cultures failed to demonstrate microorganisms. There was no evidence of other organ involvement on postoperative imaging. She was treated with prednisone with improvement of symptoms and subsequently required methotrexate to treat left eye pain and blurred vision, 29months after her surgery. Achieving treatment control in patients with pituitary and hypothalamic improvement in sarcoidosis still remains a challenge. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract 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.

  6. Anomalies in the dominant sarcoidosis paradigm justify its displacement.

    Reich, Jerome M

    2017-04-01

    The prevailing paradigm defines sarcoidosis as a disease of unknown etiology characterized by a systemic noncaseating epithelioid granulomatous response (SGR). This formulation fails to account for the elusiveness of the etiological agent, the nature of the Kveim response, the paradox of cutaneous delayed type hypersensitivity anergy in a setting of intense immune response and the appearance of SGR, indistinguishable from sarcoidosis, in persons with lymphohematogenous and solid neoplasms and a variety of cellular immune deficiencies. Displacing this formulation with an evidence-based alternative in which the SGR is viewed as an etiologically diverse, primitive immunological fallback due to inefficient cellular immune processing eliminates these shortcomings, providing a unifying accounting for the puzzles and violations of expectations associated with the prevailing paradigm. Its clinical import resides in the reported annual three-percent increase in sarcoidosis mortality in the past two decades (Swigris et al., 2011), which may be attributable, in part, to unneeded suppressive treatment.

    The antigen pathway of cutaneous sarcoidosis remains obscure. We have investigated topographic involvement of inflammatory cells and lymphatic vessels. Eleven cutaneous biopsies from eight patients were studied, along with controls from other granulomatous disorders and various skin lesions. Markers for lymphocytes, dendritic cells (DCs), and lymphatic vessel endothelial cells were detected using immunohistochemistry. S100(+) and CD1a(+) immature DCs (Langerhans cells) occurred more frequently within the epidermis, whereas S100(+), fascin(+), or CD83(+) maturing DCs occurred more frequently beneath the epithelium in cutaneous sarcoidosis cases than in controls (e.g. CD83, cutaneous sarcoidosis vs. other granulomatous disorders: r = 0.557, p = 0.011). Fascin(+) and CD83(+) mature DCs were often closely attached to CD3(+) T-lymphocytes around dermal granulomas. D2-40(+) lymphatic vessels were often found surrounding dermal granulomas, especially those located in the deeper dermis, in contrast to fascin(+) blood vessels. Antigen-capturing by immature DCs seems to take place initially in the epidermis, followed by maturation of DCs. These mature DCs may present the processed antigen to T-lymphocytes that cause dermal granulomas either in the interstitium of the upper dermis, or in or around lymphatic vessels of the lower dermis. Environmental antigen could be verified by skin test.

    New approaches to define factors underlying the immunopathogenesis of pulmonary diseases including sarcoidosis and tuberculosis are needed to develop new treatments and biomarkers. Comparing the blood transcriptional response of tuberculosis to other similar pulmonary diseases will advance knowledge of disease pathways and help distinguish diseases with similar clinical presentations. To determine the factors underlying the immunopathogenesis of the granulomatous diseases, sarcoidosis and tuberculosis, by comparing the blood transcriptional responses in these and other pulmonary diseases. We compared whole blood genome-wide transcriptional profiles in pulmonary sarcoidosis, pulmonary tuberculosis, to community acquired pneumonia and primary lung cancer and healthy controls, before and after treatment, and in purified leucocyte populations. An Interferon-inducible neutrophil-driven blood transcriptional signature was present in both sarcoidosis and tuberculosis, with a higher abundance and expression in tuberculosis. Heterogeneity of the sarcoidosis signature correlated significantly with disease activity. Transcriptional profiles in pneumonia and lung cancer revealed an over-abundance of inflammatory transcripts. After successful treatment the transcriptional activity in tuberculosis and pneumonia patients was significantly reduced. However the glucocorticoid-responsive sarcoidosis patients showed a significant increase in transcriptional activity. 144-blood transcripts were able to distinguish tuberculosis from other lung diseases and controls. Tuberculosis and sarcoidosis revealed similar blood transcriptional profiles, dominated by interferon-inducible transcripts, while pneumonia and lung cancer showed distinct signatures, dominated by inflammatory genes. There were also significant differences between tuberculosis and sarcoidosis in the degree of their transcriptional activity, the heterogeneity of their profiles and their transcriptional response to treatment.

    To investigate if there are dust particles in the cells of granulomas of sarcoidosis and analyze its composition and the possible correlation between the sarcoidosis and the composition of dust particles. The samples of 50 patients with sarcoidosis and 6 patients with silicosis as control were collected by biopsy and/or autopsy sampling. The pathological varieties of the granulomas and the situation of the dust particles within the cells of granulomas were observed using hematoxylin and eosin staining, Warthin-Starry silver staining, immunohistochemistry staining as well as the transmission electron microscope, and the X-Ray spectrum chemical element analysis in the samples from these two kinds of diseases. The dust particles containing silicon as the main chemical element were present in epithelioid cells and multinucleate giant cells in all the samples. The quantity of the particles deposited in sarcoidosis was less than that in the silicosis. Moreover, the dust cells were found in the granulomas and the visceral pleural lymphatic vessels in the pleura and the hilar pulmonary lymph nodes in sarcoidosis and silicosis. The pathological varieties of the granulomas in sarcoidosis and silicosis were similar. There are less silicon dust particles in the cells of granulomas of sarcoidosis than in those of the silicotic nodules, which indicates that the silicon dust particles may be related to the sarcoidosis.

    Dieterich, M; Brandt, T

    1995-02-01

    Recent animal and clinical studies on the vestibulo-ocular reflex deal with a number of physiological and clinical aspects from which three were chosen for this review: (1) the torsional vestibulo-ocular reflex and its disorders; (2) the otolith contribution to the vestibulo-ocular reflex; and (3) neurotransmitters, neuropharmacological aspects, and medical treatment. Disorders of the vestibulo-ocular reflex can be classified according to the three major planes of action, yaw plane, pitch plane, and roll plane, which equate with horizontal nystagmus, upbeat or downbeat nystagmus, and torsional nystagmus, respectively. The particular interest in the torsional vestibulo-ocular reflex arises from new methods for measuring ocular torsion, especially the three-dimensional eye-movement recordings with scleral coils. These methods make it possible to do three-dimensional analysis of the differential effects of horizontal and vertical semicircular canal function and their individual disorders of the torsional vestibulo-ocular reflex. Otolith and semicircular canal inputs converge at the level of the vestibular nuclei to subserve static graviceptive and dynamic torsional and pitch function. The elaboration of the particular sensorial weight of the input from either the otoliths or the semicircular canal is currently a challenge for both physiologists and neurologists. Disorders of otolith function, still absent from the diagnostic repertoire of most neurologists, are increasingly being reported. The most promising developments in therapeutic measures may come from research on vestibular neurotransmitters, their agonists and antagonists. A number of pharmacological agents are effective suppressants of pathological eye movements. However, systematic prospective studies are needed.(ABSTRACT TRUNCATED AT 250 WORDS)

    Sarcoidosis is a granulomatous disease of unknown etiology affecting any organ, microscopically characterized by noncaseating granulomata. Cardiac involvement in sarcoidosis has been reported. It might be symptomatic or not and even revealed by sudden death. Heart conduction system is rarely investigated at autopsy, even in cases of sudden cardiac death. We present a case of a 32-year-old woman who died suddenly. The examination of the heart conduction system revealed a cardiac sarcoidosis that could explain the sudden death. The review of clinical data of the patient revealed some symptoms consistent/in agreement with this hypothesis. Cardiac sarcoidosis remains a diagnostic challenge and can be easily missed, clinically and pathologically. The retrospective analysis of clinical data and autopsy results of fatal and unusual cases might help to better understand sarcoidosis and its clinical presentations.

    was investigated in granulomas from sarcoidosis patients with the use of immunohistochemistry. RESULTS: The HLA-G*010102/-G*0106 alleles were observed more often in sarcoidosis patients (39.4%) than in controls (26.4%), p = 0.025 (Fisher's exact test); however, not significant after correction (p(c) = 0.15). When...... HLA-G expression was investigated by immunohistochemistry in granulomas from sarcoidosis patients, weak HLA-G expression was observed in only one patient. CONCLUSIONS: HLA-G alleles that include a 14-bp sequence polymorphism in exon 8 of the HLA-G gene are observed more often in sarcoidosis patients...... than in controls. The sequence variation may influence HLA-G mRNA stability and influence the expression of soluble isoforms of HLA-G. Only rare and weak expression of HLA-G was observed in granulomas from sarcoidosis patients. More studies are needed to further elucidate the possible role for HLA...

    Sarcoidosis is a systemic disease of unknown cause, characterized by widespread non-caseating granulomas. There is a wide spectrum of radiologic manifestations in pulmonary sarcoidosis, providing challenges to radiologists. However, recognition of the key features of sarcoidosis with knowledge of its pathologic background can often allow for specific diagnosis. In this review, we describe the variety of high-resolution CT findings in pulmonary sarcoidosis along with its pathologic features as the basis for radiographic manifestations, and discuss the key features on high-resolution CT for the specific diagnosis of pulmonary sarcoidosis.

    2004-01-01

    To report two cases of ocular perforation during chalazion removal procedures leading to severe vision loss. Observational case series. Two patients presented with unilateral decreased vision after chalazion removal procedures. Complete ophthalmologic examinations were performed. Examination revealed a cherry red spot and perforation site in the first patient. In the second patient, there was an intraocular gas bubble and ischemic retina. Local anesthetic injections for procedures such as chalazia removal can result in ocular perforation. We postulate that the intraocular injections led to extremely high pressures, compromising the blood supply to the retina and optic nerve. Anesthetic injections for all procedures, even chalazia removal, should be done with great caution. It is imperative to avoid injection if ocular perforation is suspected, as the high pressure may cause the majority of the visual morbidity.

    Pediatric genetic ocular tumors include malignancies like retinoblastoma and phakomatosis like neurofibromatosis, tuberous sclerosis, von Hippel-Lindau syndrome, and nevoid basal cell carcinoma syndrome. 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. This review discusses the various pediatric genetic ocular tumors discussing the clinical manifestation, diagnosis and treatment.

    2005-04-01

    To describe the presentation and treatment of a Taser penetrating ocular injury. Case report. A 50-year-old man with a Taser injury 1.5 cm below the right lower eyelid margin was admitted to the emergency department of a tertiary hospital. The case report describes the ophthalmic assessment, investigation, treatment, and outcome of the Taser barb penetrating ocular injury. The Taser has a fish hook barb that caused a full-thickness wound adequately large for vitreous to escape when the Taser was removed. Consequently, the scleral wound was repaired and cryopexy was performed. The affected eye made a satisfactory recovery, and the visual acuity was 6/9 with a pinhole 1 week after operation. Any Taser injury around the orbits should raise the suspicion of a penetrating ocular injury. In likely cases, removal of the Taser should be performed in an operating theater under general anesthesia.

    Feline ocular emergencies include any ophthalmic condition that has rapidly developed or is the result of trauma to the eye or periocular structures. Common feline emergencies include proptosis, lid lacerations, corneal ulcers, and foreign bodies. Complete ophthalmic examination including procurement of the minimal ophthalmic database (Schirmer tear test, fluorescein stain, and intraocular pressure measurement) should be obtained whenever possible to ensure that the complete and correct diagnosis is made. Concern for the patient's vision and ocular comfort should guide the practioner's diagnostic and therapeutic plan. This article reviews some of the more common feline ocular emergencies, including conditions affecting the orbit and globe, adnexa, conjunctiva, and cornea. Feline uveitis, glaucoma, and lenticular diseases are covered more thoroughly elsewhere in this issue.

    2006-02-01

    Sarcoidosis is a multisystemic disease having unknown cause, characterized by non-caseating granulomatous inflammation of the organs involved. It predominantly affects the respiratory tract, with preference for the lower tract and less frequently affects the upper respiratory tract (nose, paranasal sinuses and larynx). It manifests non-specifically, with symptoms secondary to the obstruction of the airway. It can be confused with other more common disorders in our setting, such as tuberculosis. We conduct a review, fundamentally focusing on the diagnosis and treatment due to their difficulty.

    The HLA class II (DRB1 and DQB1) associations with sarcoidosis have been studied by several groups but often without consistent results. In this paper, we consider the hypothesis that observed inconsistencies relate to distinct, genetically encoded disease phenotypes which differ in prevalence between centres. We therefore typed HLA-DRB1 and DQB1 in 340 UK, 139 Dutch and 163 Japanese sarcoidosis patients and, respectively, 354, 218 and 168 healthy controls from these populations. We applied consistent phenotyping and genotyping and investigated associations between HLA class II alleles and distinct disease phenotypes within and between ethnic groups. DRB1*01 and DQB1*0501 are protective against all manifestations of sarcoidosis. Lung-predominant sarcoidosis is associated with DRB1*12 and *14. Löfgren's syndrome is a common sarcoidosis phenotype in the Dutch and is strongly associated with the DRB1*0301 allele. This phenotype is not seen among the Japanese in whom DRB1*0301 is absent. The same allele is protective for UK uveitis. Sarcoid uveitis is common in Japan. The DRB1*04–DQB1*0301 haplotype is a risk factor for this disease manifestation in Japanese and UK subjects but protective for sarcoidosis overall. We show that distinct sarcoidosis phenotypes have similar genetic associations across ethnic groups. The disease case mix differs between centres and may be explained by different ethnic allelic frequencies. PMID:20685690

    Since the introduction of anti-tumour necrosis factor [TNF] therapy in inflammatory diseases, paradoxical reactions are increasingly being reported. One of these paradoxical reactions is the development of sarcoidosis-like lesions. This presentation is paradoxical since anti-TNF therapy can also be therapeutic in refractory cases of sarcoidosis. We report two cases of sarcoidosis-like lesions under anti-TNF therapy. Both were patients with inflammatory bowel disease [IBD], treated successfully with adalimumab. Next, we reviewed the literature for similar cases. Medical subject heading terms 'adalimumab', 'infliximab', 'etanercept', 'golimumab' or 'certolizumab', and 'sarcoidosis' were used to perform key word searches of the PubMed database. We identified 90 reported cases of sarcoidosis-like lesions, which developed during anti-TNF therapy. In most cases, the anti-TNF drug involved was etanercept. The median age was 43 years and there was a predominance of female patients. The underlying disease was rheumatoid arthritis in most cases, followed by ankylosing spondylitis and psoriasiform arthritis. In six cases, the underlying disease was IBD. In 71 cases there was at least a partial resolution by discontinuation of the anti-TNF treatment, initiation of steroids or both. Re-initiation of anti-TNF therapy gave relapse in seven out of 20 cases. Sarcoidosis-like lesions are increasingly reported during anti-TNF treatment. Vigilance is appropriate when patients present with symptoms compatible with sarcoidosis.

    Full Text Available 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.

    2015-01-01

    Full Text Available Introduction. The splenic involvement is common in sarcoidosis, but its real frequency is still obscure, depending doubtless on the method of splenomegaly detection. Splenomegaly may be accompanied with pain or anemia, leucopenia and thrombocytopenia. Objective. The aim of this study was to investigate the frequency of splenomegaly related to clinical characteristics of sarcoidosis and to solve the dilemma - whether to introduce medicaments, and when to perform splenectomy. Methods. The method of the study is a retrospective and prospective analysis of the patients’ material. Results. The study included 540 patients with sarcoidosis in a 20-year period. Of them, 26% had splenomegaly detected by computerized tomography screening. Splenomegaly was more frequently registered in the patients with a longer history of sarcoidosis (38%, as compared to those with a shorter history of the disease (23% (p<0.05. Splenomegaly was more frequently registered in the patients with other extrapulmonary lesions detected (33% than in those who had no extrapulmonary manifestations of sarcoidosis (17% (p<0.01. Indications, possible benefits and complications of splenectomy were analysed in 11 sarcoidosis patients undergoing this intervention for various reasons, of which the follow-up period ranged from one to 20 years. Conclusion. Splenomegaly was more frequent in chronic cases or in the patients with established sarcoid lesions of other extrapulmonary organs. The primary treatment of uncomplicated symptomatic splenic sarcoidosis includes medicamentous therapy. Occasionally, splenectomy is required. Prognostically, splenomegaly indicates an unfavorable course of the disease.

  15. Immune response CC Chemokines, CCL2 and CCL5 are associated with Pulmonary Sarcoidosis

    Palchevskiy, Vyacheslav

    2011-04-04

    Abstract Background Pulmonary sarcoidosis involves an intense leukocyte infiltration of the lung with the formation of non-necrotizing granulomas. CC chemokines (chemokine (C-C motif) ligand 2 (CCL2)-CCL5) are chemoattractants of mononuclear cells and act through seven transmembrane G-coupled receptors. Previous studies have demonstrated conflicting results with regard to the associations of these chemokines with sarcoidosis. In an effort to clarify previous discrepancies, we performed the largest observational study to date of CC chemokines in bronchoalveolar lavage fluid (BALF) from patients with pulmonary sarcoidosis. Results BALF chemokine levels from 72 patients affected by pulmonary sarcoidosis were analyzed by enzyme-linked immunosorbent assay (ELISA) and compared to 8 healthy volunteers. BALF CCL3 and CCL4 levels from pulmonary sarcoidosis patients were not increased compared to controls. However, CCL2 and CCL5 levels were elevated, and subgroup analysis showed higher levels of both chemokines in all stages of pulmonary sarcoidosis. CCL2, CCL5, CC chemokine receptor type 1 (CCR1), CCR2 and CCR3 were expressed from mononuclear cells forming the lung granulomas, while CCR5 was only found on mast cells. Conclusions These data suggest that CCL2 and CCL5 are important mediators in recruiting CCR1, CCR2, and CCR3 expressing mononuclear cells as well as CCR5-expressing mast cells during all stages of pulmonary sarcoidosis.

    2005-01-01

    Full Text Available Leptospiral uveitis is a common entity in tropical countries. Ocular manifestations are noted in the second phase of illness, but these remain under-diagnosed mainly because of the prolonged symptom-free period that separates the systemic manifestations from detection of ocular manifestations.Varying ophthalmic presentations and the intrinsic nature of different types of uveitis to mimic one another also challenge the accuracy of the diagnosis. Of the individual ocular signs, the combination of acute, non-granulomatous, panuveitis, hypopyon, vasculitis, optic disc edema, membranous vitreous opacities and absence of choroiditis or retinitis have high predictive value for the clinical diagnosis of leptospiral uveitis. Geographic location of the patient, occupation, socio-economic status, risk factors related to exposure, past history of fever or jaundice also aid in diagnosis.Steroids are the mainstay of treatment for leptospiral uveitis. Depending upon the severity and anatomical location of inflammatory lesion, topical, peri-ocular and/or systemic steroids are given. The prognosis is generally good, even when the inflammation is severe.

  1. Clinicopathological study of glomerular diseases associated with sarcoidosis: a multicenter study

    Science.gov (United States)

    2013-01-01

    Background The association between sarcoidosis and glomerular diseases has not been extensively investigated in a large series and the potential features of this uncommon association remain to be determined. Methods We retrospectively identified 26 patients with biopsy-proven glomerular lesions that occurred in a sarcoidosis context. Potential remission of glomerular disease and sarcoidosis under specific treatment (steroid and/or immunosuppressive agents) was recorded for all patients. Demographic, clinical and biological characteristics were assessed at the time of kidney biopsy for each patient. Therapeutic data were analyzed for all patients. Results Glomerular disease occurred after the diagnosis of sarcoidosis in 11 of 26 cases (42%) (mean delay of 9.7 years). In six patients (23%), the glomerulopathy preceded the sarcoidosis diagnosis (mean delay 8 years). In the last nine patients (35%), both conditions occurred simultaneously. The most frequent glomerular disease occurring in sarcoidosis patients was membranous nephropathy in eleven cases. Other glomerular lesions included IgA nephropathy in six cases, focal segmental glomerulosclerosis in four patients, minimal change nephrotic syndrome for three patients and proliferative lupus nephritis in two patients. Granulomatous interstitial nephritis was associated with glomerular disease in six patients and was exclusively found in patients in whom the both disease occurred simultaneously. In nine patients with simultaneous glomerular and sarcoidosis diseases, we observed a strong dissociation between glomerular disease and sarcoidosis in terms of steroid responsiveness. At the end of the follow-up (mean of 8.4 years), six patients had reached end-stage renal disease and three patients had died. Conclusions A wide spectrum of glomerular lesions is associated with sarcoidosis. The close temporal relationship observed in some patients suggests common causative molecular mechanisms of glomerular injury but

    BACKGROUND Laryngeal sarcoidosis is a rare extrapulmonary manifestation of sarcoidosis, accounting for 0.33-2.1% of cases. A life-threatening complication of laryngeal sarcoidosis is upper airway obstruction. In this report we describe our experience in the acute and chronic care of a patient who required an emergent tracheostomy, with the aim to provide further insight into this difficult to manage disease. CASE REPORT A 37-year-old African American female with a 10-year history of stage 1 sarcoidosis presented with severe dyspnea. Laryngeal sarcoidosis was diagnosed three years previously, and she remained stable on low-dose prednisone until six months prior to admission, at which time she self-discontinued her prednisone for the homeopathic treatment Nopalea cactus juice. Her physical examination was concerning for impending respiratory failure as she presented with inspiratory stridor and hoarseness. Laryngoscopy showed a retroflexed epiglottis obstructing the glottis with edematous arytenoids and aryepiglottic folds. Otolaryngology performed an emergent tracheostomy to secure her airway and obtained epiglottic biopsies, which were consistent with sarcoidosis. She was eventually discharged home on prednisone 60 mg daily. Following months of corticosteroids, a laryngoscopy showed the epiglottis continuing to obstruct the glottis. The addition of methotrexate to a tapered dosage of prednisone 10 mg daily was unsuccessful, and she remains on prednisone 20 mg daily for disease control. CONCLUSIONS Laryngeal sarcoidosis, a rare extrapulmonary manifestation of sarcoidosis, uncommonly presents as the life-threatening complication of complete upper airway obstruction. As such, laryngeal sarcoidosis is associated with significant morbidity and mortality, requiring a high index of suspicion for timely diagnosis and treatment.

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

    The role of surgery in the onset of sarcoidosis is unclear. We investigated whether surgery is an internal environmental factor for sarcoidosis onset within the Japanese population. We enrolled 222 patients diagnosed with sarcoidosis (78 men, 144 women) who were admitted to our department between 1984 and 2012. We also enrolled 529 control subjects (251 men, 278 women), who were matched for sex, age at admission, and year of admission. Surgical history, family history, and smoking status were evaluated. Multivariate analysis correlated history of appendectomy (OR, 1.55; 95% CI, 1.05-2.29) and tonsillectomy (OR, 2.79; 95% CI, 0.91-8.56) with the occurrence of sarcoidosis; other surgical procedures had no correlation. In women, appendectomy had a stronger association with sarcoidosis (OR, 1.69; 95% CI, 1.05-2.73), as opposed to that in men (OR, 1.39; 95% CI, 0.68-2.85). This association was greater in women aged ≥45 years than in those aged sarcoidosis in women (OR, 3.30; 95% CI, 0.88-12.39), than in men (OR, 1.26; 95% CI, 0.10-16.52). ORs for sarcoidosis were 5.55 (95% CI, 2.02-15.27) and 0.97 (95% CI, 0.52-1.84) in women aged ≥45 years with a history of appendectomy at sarcoidosis onset, suggesting their potential protective role against sarcoidosis development. Further studies are needed to minimize possible confounding factors. Copyright © 2017 The Japanese Respiratory Society. Published by Elsevier B.V. All rights reserved.

    2014-01-01

    Full Text Available Introduction: The differential diagnosis of sarcoidosis creates a challange due to tuberculosis also having lung and lymph node involvement. Because both diseases show granulomatous inflammation, it may not be possible to distinguish tuberculosis and sarcoidosis in pathological specimens. As a result of the complexity in the differential diagnosis of sarcoidosis and tuberculosis, new markers for differentiation are being investigated. Objective: The aim of our study is to investigate the value of neutrophil/lymphocyte ratio (NLR as a possible marker in differentiating sarcoidosis and tuberculosis. Materials and Methods: In our study, 51 acid-fast bacilli (AFB positive and/or culture-positive patients with pulmonary tuberculosis, ​​40 patients with biopsy-proven sarcoidosis and a control group consisting of 43 patients were included. In our study, information was collected retrospectively based on hospital records. Results: Leukocyte and neutrophil counts, NLR, erythrocyte sedimentation rate (ESR, C-reactive protein (CRP were significantly higher, and albumin was significantly lower in the tuberculosis group compared with sarcoidosis (for all parameters P < 0.001. The most appropriate cut-off value of NLR to distinguish tuberculosis from sarcoidosis was determined as 2.55. For this cut-off value of NLR there was 79% sensitivity, 69% specificity, 73% positive predictive value (PPV, 75% negative predictive value (NPV, and area under the curve (AUC was 0.788. For differentiation of sarcoidosis from tuberculosis, accuracy of the NLR test according to this cut-off value was found as 76%. Conclusion: NLR as a little known marker in respiratory medicine was found to be supportive in differentiation of tuberculosis and sarcoidosis. More studies on this issue is needed.

    Fraction of end tidal exhaled nitric oxide (FeNO) has been introduced as a non-invasive marker of airway inflammation in patients with asthma and may have value in monitoring disease activity in patients with sarcoidosis. This pilot study explored: 1) feasibility of the multiple flow rates maneuver to estimate alveolar (C(AlV)NO) and airway wall (J(AW)NO) NO in patients with sarcoidosis; and 2) utility of exhaled NO (FeNO, C(Alv)NO and J(AW)NO) measurements to detect and monitor treatment response in patients with active pulmonary sarcoidosis. Patients with sarcoidosis (n = 42) and healthy non-smokers (n = 20) underwent FeNO measurement at 7 flow-rates (50 to 400 ml/s). Using the Tsoukias and George (1998) model, C(Alv)NO and J(AW)NO were estimated. Both patients and healthy non-smokers were able to perform the multiple flow rates maneuver without discomfort, with first measurement success rate of 57% and 65%, respectively. No significant difference was found between patients with sarcoidosis and healthy non-smokers in exhaled NO. None were correlated with pulmonary function tests, except a significant negative correlation between C(Alv)NO and FVC% (p = 0.001) and DLCO% (p = 0.012). In 8 patients with active sarcoidosis, FeNO, C(Alv)NO or J(AW)NO were not different from those of patients with inactive sarcoidosis. Treatment of active sarcoidosis using oral prednisone and methotrexate did not show any consistent pattern of changes in C(Alv)NO or J(AW)NO. Due to a large inter-subject variability and difficulty controlling use of the inhaled corticosteroids, exhaled NO measurement did not appear to be a clinically useful method of monitoring disease progression in sarcoidosis.

    To investigate the risk of malignancy in patients with sarcoidosis in a population-based cohort. A cohort of Olmsted County, Minnesota, residents diagnosed with sarcoidosis between January 1, 1976 and December 31, 2013 was identified based on individual medical record review. For each sarcoidosis subject, 2 sex- and age-matched comparator subjects without sarcoidosis were randomly selected. Cases and comparators were then cross-indexed with the Mayo Clinic Cancer Registry, which collected data on every type of malignancy except for nonmelanoma skin cancer, for malignancy ascertainment. A total of 345 incident cases of sarcoidosis and 690 comparators were identified. There was no difference in the prevalence of malignancy at the index date between the 2 groups (4.3% among cases and 4.3% among comparators; P = 1.0). During followup, 36 patients with sarcoidosis and 91 subjects without sarcoidosis developed malignancy, with a cumulative incidence at 10 years of 3.8% and 7.1%, respectively. The difference corresponded to a hazard ratio (HR) of 0.72 (95% confidence interval [95% CI] 0.49-1.06). The cumulative incidences at 10 years for individual types of malignancy were also similar between the 2 groups, with nonsignificant HRs. However, subgroup analysis found that cases with extrathoracic involvement were at higher risk of incident hematologic malignancy compared with cases without extrathoracic involvement (HR 1.87 [95% CI 1.09-3.22]). Risk of malignancy was similar among patients with sarcoidosis compared to nonsarcoidosis subjects. However, the risk of incident hematologic malignancy was significantly higher among patients with sarcoidosis with extrathoracic involvement compared to patients without extrathoracic disease. © 2016, American College of Rheumatology.

    Purpose: To evaluate the potential of ECG-gated breath-hold MRI in diagnosing acute myocardidits. Material and methods: Cardiac MRI was performed on 21 consecutive patients with suspected myocarditis. ECG-gated breath-hold T2-weighted images with fat suppression were acquired in 3 standard views. T1-weighted imaging (FLASH) was performed 10 min after IV administration of Gd-DTPA. Laboratory data included creatine kinase, troponin T and serological tests, ECG findings and echocardiography. Imaging findings were retrospectively compared to the discharge diagnoses. Signal alterations were semiquantitatively classified. Results: Acute myocarditis was diagnosed in 9 patients and cardiac sarcoidosis in 2 patients. Late enhancement was observed in 4 patients with acute myocarditis and in both patients with cardiac sarcoidosis. Semiquantitative evaluation revealed 9 true positive, 9 true negative, 1 false positive and 2 false negative results. Conclusion: Cardiac MRI has the potential to detect acute myocarditis and to diagnose cardiac sarcoidosis. Late enhancement of Gd-DTPA can be found in both viral myocarditis and cardiac sarcoidosis.

    Full Text Available Although pulmonary arterial hypertension is usually associated with advanced stages of sarcoidosis, its occurrence in early stage disease is rare. Herein, a case of associated pulmonary arterial hypertension in the setting of Hashitoxicosis and stage II pulmonary sarcoidosis is reported. The case of associated pulmonary arterial hypertension occurred in a young female without clinically significant medical history and who completely recovered after receiving oral corticotherapy only. Furthermore, this case report suggests the presence of an interaction between pulmonary arterial hypertension, sarcoidosis and Hashitoxicosis.

    Full Text Available Sarcoidosis is a multi-systemic disorder of unknown etiology, although commonly believed to be immune-mediated. Histologically, it is characterized by noncaseating granuloma which contrasts against the caseating granuloma seen in tuberculosis (TB, an infectious disease that closely mimics sarcoidosis, both clinically as well as radiologically. In TB-endemic regions, the overlapping clinico-radiological manifestations create significant diagnostic dilemma, especially since the management options are markedly different in the two entities. Part 1 of this review aims to summarize the clinical, laboratory, and imaging features of sarcoidosis, encompassing both typical and atypical manifestations, in an attempt to distinguish between the two disease entities.

    2013-08-01

    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.

    Full Text Available Purpose: To compare ocular biometric parameters in primary angle closure suspects (PACS, primary angle closure glaucoma (PACG and acute primary angle closure (APAC. Methods: This cross-sectional study was performed on 113 patients including 33 cases of PACS, 45 patients with PACG and 35 subjects with APAC. Central corneal thickness (CCT, axial length (AL, anterior chamber depth (ACD and lens thickness (LT were measured with an ultrasonic biometer. Lens-axial length factor (LAF, relative lens position, corrected ACD (CACD and corrected lens position were calculated. The parameters were measured bilaterally but only data from the right eyes were compared. In the APAC group, biometric parameters were also compared between affected and unaffected fellow eyes. Logistic regression analysis was performed to identify risk factors. Results: No statistically significant difference was observed in biometric parameters between PACS and PACG eyes, or between affected and fellow eyes in the APAC group (P>0.05 for all comparisons. However, eyes with APAC had thicker cornea (P=0.001, thicker lens (P<0.0001, shallower ACD (P=0.009, shallower CACD (P=0.003 and larger LAF (P<0.0001. Based on ROC curve analysis, lower ACD, and larger LT, LAF and CCT values were associated with APAC. In the APAC group, LAF (P<0.0001 and CCT (P=0.001 were significant risk factors. Conclusion: This study revealed no significant difference in biometric characteristics in eyes with PACS and PACG. However, larger LAF and CCT were predictive of APAC.

  15. Ocular allergy and keratoconus

    Directory of Open Access Journals (Sweden)

    Namrata Sharma

    2013-01-01

    Full Text Available Keratoconus is the most common corneal ectatic disorder, the cause of which is largely unknown. Many factors have been implicated, and the ocular allergy is being one of them. The commonly proposed pathogenesis includes the release of inflammatory mediators due to eye rubbing which may alter the corneal collagen and lead to corneal ectasias. The onset of keratoconus is often early in cases associated with allergy and routine corneal topography may detect subtle forms of keratoconus. These cases may require early keratoplasty and are at an increased risk of having acute corneal hydrops. Surgical outcomes are similar to primary keratoconus cases. However, post-operative epithelial breakdown may be a problem in these cases. Control of allergy and eye rubbing is the best measure to prevent corneal ectasias in cases of ocular allergy.

    2017-07-01

    Sclerodermatomyositis is an overlap syndrome of myositis and scleroderma, with dermatological, muscular and joint involvement, but may also present with ocular manifestations. A 57 year-old woman presented with ophthalmological manifestations, including scleral thinning 360°, and the presence of cells in the anterior and posterior chamber. Oriented physical examination and laboratory studies led to the diagnosis, with the need for systemic treatment. Sclerodermatomyositis is a rare disease. Its diagnosis needs thorough clinical and laboratory studies, and its management should be multidisciplinary when inflammatory ocular manifestations may be present.

  18. Microsporidia: Emerging Ocular Pathogens

    Directory of Open Access Journals (Sweden)

    Joseph J

    2005-01-01

    Full Text Available Microsporidia are eukaryotic, spore forming obligate intracellular parasites, first recognized over 100 years ago. Microsporidia are becoming increasingly recognized as infectious pathogens causing intestinal, ocular, sinus, pulmonary, muscular and renal diseases, in both immunocompetent and immunosuppressed patients. Ocular microsporidiosis, though uncommon, could be isolated or part of systemic infections. It occurs mainly in two forms: keratoconjunctivitis form, mostly seen in immunocompromised individuals; stromal keratitis form seen in immunocomptetant individuals. Recent reports indicate increasing number of cases of ocular microsporidiosis in immunocompetent individuals. The ocular cases present as superficial keratitis in AIDS patients, and these differ in presentation and clinical course from the cases seen in immunocompetent individuals which mainly appear to be as deep stromal keratitis. For most patients with infectious diseases, microbiological isolation and identification techniques offer the most rapid and specific determination of the etiologic agent, however this does not hold true for microsporidia, which are obligate intracellular parasites requiring cell culture systems for growth. Therefore, the diagnosis of microsporidiosis currently depends on morphological demonstration of the organisms themselves, either in scrapings or tissues. Although the diagnosis of microsporidiosis and identification of microsporidia by light microscopy have greatly improved during the last few years, species differentiation by these techniques is usually impossible and electron microscopy may be necessary. Immuno fluorescent-staining techniques have been developed for species differentiation of microsporidia, but the antibodies used in these procedures are available only at research laboratories at present. During the last 10 years, molecular techniques have been developed for the detection and species differentiation of microsporidia.

    2016-01-01

    Full Text Available Intraorbital sarcoidosis presenting externally as a solitary eyelid mass has been described in the literature as isolated case reports. We describe a rare case of asymptomatic sarcoidosis with orbital mass as the presenting feature in a young woman. The lesion was excised with the clinical possibility of a thrombosed varix. On histology, the lesion was characterized by numerous nonnecrotizing epithelioid cell granulomas with several multinucleated giant cells containing abundant asteroid bodies and oxalate crystals. No tubercular bacilli were detected. A diagnosis of sarcoidosis was rendered and on further clinical work-up, she was detected to have hilar lymphadenopathy. Sarcoidosis should be considered in the differential diagnosis of orbital mass as it could be the initial manifestation of the disease process.

    Full Text Available Abstract Introduction Takayasu arteritis (TA is a chronic vasculitis of unknown origin, affecting mainly the aorta and its main branches. As a result of the inflammation, stenosis, occlusion or dilatation of the involved vessels may occur and cause a wide range of symptoms. It has been described in association with various auto-immune disorders (mainly inflammatory digestive tract diseases. However, only few cases of TA associated with sarcoidosis have been reported, raising the question of an association by chance. Case report We report a case of a 34 year-old woman, with one year history of sarcoidosis, who presented with asymmetric high hypertension revealing inflammatory humeral, axillary and subclavian arteritis related to TA, successfully treated by steroid and immunosuppressive therapy(MethotrexateR. Conclusion TA and sarcoidosis may be related, rising the hypothesis that TA or Takayasu arteritis-like granulomatous vasculitis may be, in fact, a complication of sarcoidosis.

    The distinction between ocular sebaceous carcinoma, poorly differentiated ocular squamous cell carcinoma and ocular basal cell carcinoma can be challenging. An appropriate immunohistochemical panel may help to differentiate these lesions. To determine the distribution and use of several immunostains in these specimens, formalin-fixed, paraffin-embedded tissue from several of each was studied using an immunohistochemical technique. Positive staining for cytokeratin (CK)7 was seen in 100% of sebaceous carcinomas, 77.8% of basal cell carcinomas and 67.7% of squamous cell carcinomas. One hundred percent of sebaceous and basal cell carcinomas were positive for cytokeratin CAM 5.2, while only 83.3% of squamous cell carcinomas were positive. Using epithelial membrane antigen (EMA), 100% of squamous cell carcinomas and 80% of sebaceous carcinomas were positive, while basal cell carcinomas were uniformly negative. One hundred percent of basal cell carcinomas and 80% of sebaceous carcinomas were positive for Ber-EP4, while all squamous cell carcinomas were negative. Finally, 77.8%, 20% and 16.7% of basal cell carcinomas, sebaceous carcinomas and squamous cell carcinomas showed immunoreactivity for the androgen receptor. An EMA positive, Ber-EP4 positive immunophenotype supports sebaceous carcinoma, EMA positive, Ber-EP4 negative result supports squamous cell carcinoma and an EMA negative, Ber-EP4 positive result supports basal cell carcinoma.

    Flynn, T H

    2012-02-03

    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. METHODS: Retrospective review of the case notes of 310 patients who attended Cork University Hospital or Waterford Regional Hospital between 1 January 1994 and 31 December 2002 with ocular injuries sustained during a hurling match. A confidential questionnaire on reasons for non-use of protective headgear and eye wear was completed by 130 players. 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.

    2016-01-01

    Background: One of the most alarming ocular injury trends in recent years has been the proliferation of paintball guns and the proportional increase in the number of ocular eye injuries caused by paintballs. To describe five cases of paintball eye injuries that resulted in loss of functional vision in four of them. We conducted a retrospective review of the clinical course in five patients with paintball eye injuries treated in the ophthalmology departments of two medical centers. Five young males were evaluated for paintball injuries caused by blunt trauma. There was one case of full-thickness laceration (globe rupture). Four patients required one to five surgical interventions: three of these involved the removal of traumatic cataract including two eyes with significant zonular dehiscence treated by lens capsule conservation using anchoring devices, one retinal surgery and two glaucoma filtration surgeries. However, final visual outcome was not favorable due to irreversible retinal damage. Paintball trauma often results in significant ocular injury and loss of functional vision despite successful surgical intervention. Most injuries occur in under-supervised settings and are easily preventable. Improved safety measures, strict regulation enforcement and appropriate public education could prevent such serious damage.

    Data on clinical manifestations and outcome of hepatic sarcoidosis are scarce. This study aimed to use a population-based cohort of patients with incident sarcoidosis to better describe the characteristics of hepatic sarcoidosis. A cohort of incident cases of sarcoidosis in Olmsted County, MN, USA, from 1976 to 2013 was identified from the database. Diagnosis was verified by individual medical record review. Confirmed cases of sarcoidosis were then reviewed for liver involvement. Data on clinical manifestations, imaging study, liver biochemical tests, treatment, and outcome were collected. Cumulative incidence of cirrhosis adjusted for the competing risk of death was estimated. A total of 345 cases of incident sarcoidosis were identified. Of these, 19 cases (6%) had liver involvement (mean age 46.1 years, 53% female and 79% Caucasian). Most patients had asymptomatic liver disease and were discovered in pursuit of abnormal biochemical tests and imaging studies. Alkaline phosphatase (ALP) and gamma-glutamyl transferase (GGT) were elevated in the majority of patients (88 and 90%, respectively). Elevated transaminases were less common and less severe. About half of patients had abnormal imaging study with hypodense nodular lesions being the most common abnormality (six patients) followed by hepatomegaly (three patients). Liver biopsy revealed non-caseating granuloma in 88% (14 of 16 patients). A total of four patients developed cirrhosis. Involvement of the liver by sarcoidosis was seen in 6% of patients with sarcoidosis. The majority of patients were asymptomatic. Elevated ALP and GGT were the most common abnormal biochemical tests. Liver biopsy revealed non-caseating granuloma in almost all cases. Cirrhosis was seen in a significant number of patients. Generalizability of the observations to other populations may be limited, as the studied population was predominantly Caucasian. The prevalence of liver disease may be higher in more diverse populations.

    Sarcoidosis is a chronic, multisystemic disease commonly affecting the lungs and lymphatic system and is characterized by the formation of noncaseating granulomas. Although several reports are available on cases developing both sarcoidosis and cancer metachronously, cases of simultaneous diagnosis of these diseases have rarely been reported. A 67-year-old woman diagnosed with endometrial cancer had developed systemic lymph node swelling, including bilateral hilar, paraaortic, and a few pelvic...

    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 ...

    To assess the clinical characteristics, diagnosis, and outcome of cardiac sarcoidosis in a single institution sarcoidosis clinic. Patients with cardiac sarcoidosis were identified using refined World Association of Sarcoidosis and Other Granulomatous Diseases (WASOG) criteria of highly probable and probable. Patient demographics, local and systemic treatments, and clinical outcome were collected. Of the 1,815 patients evaluated over a 6-year period, 73 patients met the WASOG criteria for cardiac sarcoidosis. The median age at diagnosis was 46 years, with a median follow-up of 8.8 years. Reduced left ventricular ejection fraction (LVEF) was the most common manifestation (54.8%). Patients with arrhythmias experienced ventricular tachycardia or severe heart block, (35.6% and 19.2%, respectively) with or without reduced LVEF. A total of 45 (61.6%) patients underwent cardiac PET scan and/or MRI, with 41 (91.1%) having a positive study. During follow-up, 10 patients (13.7%) either underwent transplant (n = 3) or died (n = 7) from sarcoidosis. Kaplan-Meier survival curves revealed 5- and 10-year survival rates of 95.5% and 93.4%, respectively. Univariate factors of age at diagnosis  40% were associated with improved survival. Cox regression analysis demonstrated that age ≥ 46 years and lack of an implanted pacemaker or defibrillator were the only independent predictors of mortality. The new WASOG criteria were able to characterize cardiac involvement in our sarcoidosis clinic. Age and lack of pacemaker or defibrillator were the significant predictors of mortality for cardiac sarcoidosis, and reduced LVEF < 40% was associated with worse prognosis.

    Full Text Available RATIONALE: New approaches to define factors underlying the immunopathogenesis of pulmonary diseases including sarcoidosis and tuberculosis are needed to develop new treatments and biomarkers. Comparing the blood transcriptional response of tuberculosis to other similar pulmonary diseases will advance knowledge of disease pathways and help distinguish diseases with similar clinical presentations. OBJECTIVES: To determine the factors underlying the immunopathogenesis of the granulomatous diseases, sarcoidosis and tuberculosis, by comparing the blood transcriptional responses in these and other pulmonary diseases. METHODS: We compared whole blood genome-wide transcriptional profiles in pulmonary sarcoidosis, pulmonary tuberculosis, to community acquired pneumonia and primary lung cancer and healthy controls, before and after treatment, and in purified leucocyte populations. MEASUREMENTS AND MAIN RESULTS: An Interferon-inducible neutrophil-driven blood transcriptional signature was present in both sarcoidosis and tuberculosis, with a higher abundance and expression in tuberculosis. Heterogeneity of the sarcoidosis signature correlated significantly with disease activity. Transcriptional profiles in pneumonia and lung cancer revealed an over-abundance of inflammatory transcripts. After successful treatment the transcriptional activity in tuberculosis and pneumonia patients was significantly reduced. However the glucocorticoid-responsive sarcoidosis patients showed a significant increase in transcriptional activity. 144-blood transcripts were able to distinguish tuberculosis from other lung diseases and controls. CONCLUSIONS: Tuberculosis and sarcoidosis revealed similar blood transcriptional profiles, dominated by interferon-inducible transcripts, while pneumonia and lung cancer showed distinct signatures, dominated by inflammatory genes. There were also significant differences between tuberculosis and sarcoidosis in the degree of their

    The purpose of this study was to evaluate the efficacy of combined albendazole and steroid treatment for uveitis caused by Toxocara canis in immunocompetent patients. Five patients (7 eyes) with ocular larva migrans syndrome (OLM) were used in this study. Toxocariasis was suspected based on clinical manifestations and confirmed by anti-toxocara IgG and Western blot analysis. Systemic albendazole (adults: 800 mg b.i.d.; children: 400 mg b.i.d.) was given in conjunction with steroids. Visual acuity before and after therapy, inflammatory response, side effects and toxicity were evaluated. Treatment resulted in an improved visual acuity in all patients. Mean initial Snellen visual acuity was 20/40, and mean final acuity was 20/20. There were no recurrences of uveitis throughout the observation period (average: 13.8 months; range: 3 days to 24 months). These findings suggest that albendazole, in combination with systemic steroids, is a useful regimen to treat ocular larva migrans syndrome.

    Sarcoidosis is an important diagnostic consideration in patients with ventricular tachycardia (VT) of unknown origin. The clinical course of VT as the primary presentation in patients with sarcoidosis is mostly unknown. This study aimed to investigate the incidence of life-threatening VT and mortality during long term follow-up in patients with sarcoidosis. We analyzed the epidemiological features of sarcoidosis in Taiwan using the National Health Insurance Research Database from 2000 to 2004. Patients with sarcoidosis were identified, and healthy controls without prior histories of structural heart disease were matched with a 1:1 propensity-score to the sarcoidosis group. The risk of life-threatening VT and mortality with sarcoidosis was analyzed. A total of 2237 sarcoidosis cases were enrolled with a matching number of healthy controls, and the baseline characteristics between the two groups were similar. After a mean follow-up of 11.4±2.15years (IQR: 12, 11.3-12), the VT incidence in the sarcoidosis group was higher than in healthy controls (0.94% [85 per 100,000 person-year] in the sarcoidosis group, and 0.09% [8 per 100,000 person-year] in healthy controls). After a multivariate adjustment including the sex, age, and other comorbidities, the VT risk was still higher in the sarcoidosis group (hazard ratio: 12.7, 95% confidence interval: 2.82-56.9; PSarcoidosis may increase the predisposition to ventricular arrhythmias with a cumulative incidence of 0.94% during a very long term follow-up of nearly 10years from initially diagnosing sarcoidosis.

    Sarcoidosis is a chronic systemic granulomatous disease of unknown etiology. Previous studies demonstrated that patients with sarcoidosis had high rates of depression and anxiety, and high magnitude of stressful life events. To date, however, studies have not examined the anxiety sensitivity in sarcoid patients and the relationship between psychopathology and symptom severity of sarcoidosis.The aims of this study were to evaluate prevalence of depression and anxiety in sarcoid patients, to assess their relationship with the disease symptom severity, and to investigate the relationship between sarcoidosis and anxiety sensitivity. Thirty three sarcoid patients and thirty three control subjects completed the following:Hospital Anxiety and Depression Scale, Anxiety Sensitivity Index-3. The prevalence of depression (29%) and anxiety (31%) was high among patients and comparable to results from other research groups. Anxiety was significantly correlated with symptom severity and was the main covariate of physical symptoms reported by sarcoid patients. Patients exhibited an increase of their total anxiety sensitivity index and had an increased number of physical concerns. These data confirmed earlier reports that anxiety and depression are common in patients with sarcoidosis and expanded on the previous results by showing that patients exhibited increased anxiety sensitivity and a fear of physical sensations. These results, together with the findings that anxiety was associated with sarcoidosis symptom severity, suggest that targeting anxiety and the physical health concerns may be important in the diagnosis and management of this disease.

    Background Recent studies show that various inflammatory diseases are regulated at the level of RNA translation by small non-coding RNAs, termed microRNAs (miRNAs). We sought to determine whether sarcoidosis tissues harbor a distinct pattern of miRNA expression and then considered their potential molecular targets. Methods and Results Genome-wide microarray analysis of miRNA expression in lung tissue and peripheral blood mononuclear cells (PBMCs) was performed and differentially expressed (DE)-miRNAs were then validated by real-time PCR. A distinct pattern of DE-miRNA expression was identified in both lung tissue and PBMCs of sarcoidosis patients. A subgroup of DE-miRNAs common to lung and lymph node tissues were predicted to target transforming growth factor (TGFβ)-regulated pathways. Likewise, the DE-miRNAs identified in PBMCs of sarcoidosis patients were predicted to target the TGFβ-regulated “wingless and integrase-1” (WNT) pathway. Conclusions This study is the first to profile miRNAs in sarcoidosis tissues and to consider their possible roles in disease pathogenesis. Our results suggest that miRNA regulate TGFβ and related WNT pathways in sarcoidosis tissues, pathways previously incriminated in the pathogenesis of sarcoidosis. PMID:22209793

    Sarcoidosis is a complex disease of unknown etiology characterized by the presence of granulomatous inflammation. Though various immune system pathways have been implicated in disease, the relationship between the genetic determinants of sarcoidosis and other inflammatory disorders has not been characterized. Herein, we examined the degree of genetic pleiotropy common to sarcoidosis and other inflammatory disorders to identify shared pathways and disease systems pertinent to sarcoidosis onset. To achieve this, we quantify the association of common variant polygenic risk scores from nine complex inflammatory disorders with sarcoidosis risk. Enrichment analyses of genes implicated in pleiotropic associations were further used to elucidate candidate pathways. In European-Americans, we identify significant pleiotropy between risk of sarcoidosis and risk of asthma (R2=2.03%; P=8.89 × 10-9), celiac disease (R2=2.03%; P=8.21 × 10-9), primary biliary cirrhosis (R2=2.43%; P=2.01 × 10-10) and rheumatoid arthritis (R2=4.32%; P=2.50 × 10-17). These associations validate in African Americans only after accounting for the proportion of genome-wide European ancestry, where we demonstrate similar effects of polygenic risk for African-Americans with the highest levels of European ancestry. Variants and genes implicated in European-American pleiotropic associations were enriched for pathways involving interleukin-12, interleukin-27 and cell adhesion molecules, corroborating the hypothesized immunopathogenesis of disease.

  1. Upregulation of neurokinin-1 receptor expression in the lungs of patients with sarcoidosis.

    2012-02-03

    Substance P (SP) is a proinflammatory neuropeptide that is secreted by sensory nerves and inflammatory cells. Increased levels of SP are found in sarcoid bronchoalveolar lavage fluid. SP acts by binding to the neurokinin-1 receptor and increases secretion of tumor necrosis factor-alpha in many cell types. We sought to determine neurokinin-1 receptor expression in patients with sarcoidosis compared with normal controls. Neurokinin-1 receptor messenger RNA and protein expression were below the limits of detection by reverse transcriptase-polymerase chain reaction and immunohistochemistry in peripheral blood mononuclear cells of healthy volunteers (n = 9) or patients with stage 1 or 2 pulmonary sarcoidosis (n = 10), but were detected in 1\\/9 bronchoalveolar lavage cells of controls compared with 8\\/10 patients with sarcoidosis (p = 0.012) and 2\\/9 biopsies of controls compared with 9\\/10 patients with sarcoidosis (p = 0.013). Immunohistochemistry localized upregulated neurokinin-1 receptor expression to bronchial and alveolar epithelial cells, macrophages, lymphocytes, and sarcoid granulomas. The patient in whom neurokinin-1 receptor was not detected was taking corticosteroids. Incubation of the type II alveolar and bronchial epithelial cell lines A549 and SK-LU 1 with dexamethasone downregulated neurokinin-1 receptor expression. Upregulated neurokinin-1 receptor expression in patients with sarcoidosis may potentiate substance P-induced proinflammatory cytokine production in patients with sarcoidosis.

  2. Imbalance between Th17 and Regulatory T-Cells in Sarcoidosis

    Full Text Available Sarcoidosis is a systemic granulomatous disease, which is thought to result from an aberrant immune response. CD4+ T lymphocytes play an important role in the development of granulomas. Previously, the immunopathogenesis of sarcoidosis was focused on Th1/Th2 disturbances. The aim of this study was to evaluate the balance between newer CD4+ T lymphocytes, i.e., Treg and Th17 cells. In our studies, a decrease in Treg cells and an increase in Th17 cells were observed in the peripheral blood and BALF of sarcoidosis patients. A significant increase in the Th17/Treg cell ratio was observed in sarcoidosis patients. After treatment with prednisone, the expression of Foxp3 mRNA was elevated in the peripheral blood, and expression of (RORγt mRNA showed a downward trend. These findings suggest that sarcoidosis is associated with an imbalance between Th17 and Treg cells in peripheral blood and BALF. Therefore, targeting the cytokines that affect the Th17/Treg ratio could provide a new promising therapy for pulmonary sarcoidosis.

    Full Text Available Sarcoidosis involves abnormal collections of inflammatory cells (granulomas which may form as nodules in multiple organs. 90% of affected patients have respiratory tract abnormalities. We present a 61-year-old male with sarcoidosis who was admitted for respiratory distress. Fibrosing mediastinitis was seen in the chest computograph. Management was conservative and included steroids, antibiotics, and oxygen therapy. Sarcoidosis and fibrosing mediastinitis are rare. Fibrosing mediastinitis is more commonly seen with histoplasmosis. We explore the clinical similarities between histoplasmosis and sarcoidosis. We also explore the potential cause and effect relationship and workup for each disease entity.

    Full Text Available PURPOSE: To determine the timing of spontaneous venous pulsation (SVP relative to the ocular circulatory cycle by using the movie tool of confocal scanning laser ophthalmoloscope. METHODS: A video recording of the fundus was obtained using a confocal scanning laser ophthalmoscope (Spectralis HRA, Heidelberg Engineering, Heidelberg, Germany at 8 frames/s in 47 eyes (15 glaucoma patients and 32 glaucoma suspects with visible pulsation of both the central retinal artery (CRA and vein (CRV. The timing of the maximum and minimum diameters of the CRA (CRA(max and CRAmin, respectively and CRV (CRV(max and CRV(min, respectively was identified during four pulse cycles. The interval between CRV(min and CRA(min, and between CRV(max and CRA(max was expressed as the number of frames and as a percentage of the ocular circulatory cycle. RESULTS: The ocular circulatory cycle (from one CRA(max to the next lasted 7.7 ± 1.0 frames (958.8 ± 127.2 ms, mean ± SD, with a mean pulse rate of 62.6 beats/min. The diameter of the CRA was increased for 2.4 ± 0.5 frames (301.9 ± 58.8 ms and decreased for 5.3 ± 0.9 frames (656.9 ± 113.5 ms. CRV(max occurred 1.0 ± 0.2 frames after CRA(max (equivalent to 13.0% of the ocular circulatory cycle, while CRV(min occurred 1.1 ± 0.4 frames after CRA(min (equivalent to 14.6% of the ocular circulatory cycle. CONCLUSIONS: During SVP, the diameter of the CRV began to decrease at early diastole, and the reduction persisted until early systole. This finding supports that CRV collapse occurs during ocular diastole.

    Dysphagia is a rare manifestation of sarcoidosis. It is more commonly the result of esophageal compression by enlarged mediastinal lymph nodes rather than direct esophageal involvement and rarely secondary to neurosarcoidosis and oropharyngeal dysphagia. We report a 54 year old female presenting with a six month history of worsening dysphagia. She denied respiratory symptoms. Physical exam was normal. ESR was 61 mm/hr. Serum ACE level was 65 mcg/L. Chest X-ray was normal. Esophagram revealed a large amount of contrast pooling in pharyngeal recesses with intermittent laryngeal aspiration. Swallow videofluorography showed a decreased retraction of the base of the tongue, limited laryngeal elevation, and a large amount of contrast pooling in pharyngeal recesses with intermittent laryngeal aspiration. EGD showed a normal opening of the upper esophageal sphincter and the cricopharyngeus appeared normal. Proximal esophageal biopsies were normal. Brain MRI with gadolinium was normal. Lumbar puncture was performed. CSF showed a moderate pleocytosis, a WBC count of 19 with 97% lymphocytes, an elevated total protein level of 85 mg/dl (15-60). Neck CT scan showed no oropharyngeal tissue thickening or infiltration, no masses or enlarged lymph nodes. Chest CT scan showed enlarged intrathoracic lymph nodes and no esophageal compression. Bronchoscopy showed the vocal cords to be intact, and the CD4/CD8 ratio in BAL was 5.3. Subcarinal lymph node EBUS biopsy revealed non caseating granulomas. The patient was started on IV methylprednisolone. Three days later, the swallow videofluorography showed a near complete response to steroids. The patient tolerated regular consistency diet with thin liquids, and she was discharged on a slow taper of prednisone over a period of three months. A unique case of isolated dysphagia unmasking bulbar neurosarcoidosis and pulmonary sarcoidosis is herein reported. Copyright © 2014 Arab Journal of Gastroenterology. Published by Elsevier Ltd. All

    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.

    Kveim-reagent (Kv) skin testing was a historical method of diagnosing sarcoidosis. Intradermal injection of treated sarcoidosis spleen tissue resulted in a granuloma response at injection site by 4-6 weeks. Previous work indicates proteins as the possible trigger of this reaction. We aimed to identify Kv-specific proteins and characterise the ex vivo response of Peripheral Blood Mononuclear Cells (PBMCs) from sarcoidosis, tuberculosis and healthy control patients when stimulated with both Kv and selected Kv-specific proteins. Kv extracts were separated by 1D-SDS-PAGE and 2D-DIGE and then underwent mass spectrometric analysis for protein identification. Sarcoidosis and control PBMCs were first stimulated with Kv and then with three selected recombinant protein candidates which were identified from the proteomic analysis. PBMC secreted cytokines were subsequently measured by Multiplex Cytokine Assay. We observed significantly increased IFN-γ and TNF-α secretion from Kv-stimulated PBMCs of sarcoidosis patients vs. PBMCs from healthy volunteers (IFN-γ: 207.2 pg/mL vs. 3.86 pg/mL, p = 0.0018; TNF-α: 2375 pg/mL vs. 42.82 pg/mL, p = 0.0003). Through proteomic approaches we then identified 74 sarcoidosis tissue-specific proteins. Of these, 3 proteins (vimentin, tubulin and alpha-actinin-4) were identified using both 1D-SDS-PAGE and 2D-DIGE. Data are available via ProteomeXchange with identifier PXD005150. Increased cytokine secretion was subsequently observed with vimentin stimulation of sarcoidosis PBMCs vs. tuberculosis PBMCs (IFN-γ: 396.6 pg/mL vs 0.1 pg/mL, p = 0.0009; TNF-α: 1139 pg/mL vs 0.1 pg/mL, psarcoidosis PBMCs compared to PBMCs from healthy controls (IFN-γ: 396.6 pg/mL vs. 0.1 pg/mL, p = 0.014; TNF-α: 1139 pg/mL vs 42.29 pg/mL, p = 0.027). No difference was found in cytokine secretion between sarcoidosis and control PBMCs when stimulated with either tubulin or alpha-actinin-4. Stimulation with both Kveim reagent and vimentin induces a specific pro

    Full Text Available Allogeneic hematopoietic stem cell transplantation (HSCT is a well-established therapeutic option for a range of inherited and acquired hematological disorders. However, graft-versus-host disease (GVHD remains the leading cause of non-relapse mortality in allogeneic HSCT recipients. Ocular involvement occurs in up to 80% of chronic GVHD patients. In our cases, the diagnosis of vitamin A deficiency was suspected for GVHD patients. Serum vitamin A measurements were conducted to confirm clinical suspicions. Our study revealed significant decrease in serum levels of vitamin A in chronic liver GVHD patients. Although there have been many studies evaluating ocular manifestations in patients with GVHD, the present study is, to our knowledge, the first to study the relationship between vitamin A and ocular manifestations of GVHD in humans. Our data suggest that vitamin A deficiency affects the severity of ocular GVHD in adults.

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.

    Ocular myiasis though rare, is usually found in association with basal cell carcinoma. It is rarer still in tumors other than basal cell carcinoma. We report a case of ocular myiasis in a glioma which is hitherto unreported to the best of our knowledge. A 50 year old male presented with bleeding and maggots emanating from a tumourous outgrowth which had replaced his right eye. He complained of swelling and pain in his right eye for the last 2 years. Manual removal of maggots was carried out following which he underwent total excision of the mass and local debridement. Biopsy of the mass was consistent with astrocytoma. Myiasis though rare should be suspected in long standing neglected lesions with suggestive history. Infection, ischemic necrosis and malignancy coupled with overcrowding, poor living conditions, presence of excessive arthropods in the locality and low levels of hygiene drastically increase the risk of myiasis. © NEPjOPH.

    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 sarcoidosis patients having co-occurrence of associated respiratory diseases. Moreover, age was an important risk factor for re-hospitalization. PMID:26987059

    It is vital to identify cardiac involvement (CI) in patients with sarcoidosis as the condition could initially lead to sudden cardiac death. Although the T wave amplitude in lead aVR (TWAaVR) is reportedly associated with adverse cardiac events in various cardiovascular diseases, only scarce data are available concerning the utility of lead aVR in identifying CI in patients with sarcoidosis. We retrospectively investigated the diagnostic values of TWAaVR in patients with sarcoidosis in comparison with conventional electrocardiography parameters such as bundle branch block (BBB). From January 2006 to December 2014, 93 consecutive patients with sarcoidosis were enrolled (mean age, 55.7 ± 15.7 years; male, 31 %; cardiac involvement, n = 26). TWAaVR showed the greatest sensitivity (39 %) and specificity (92 %) in distinguishing between sarcoidosis patients with and without CI, at a cutoff value of -0.08 mV. The diagnostic value of BBB for cardiac involvement was significantly improved when combined with TWAaVR (sensitivity: 61-94 %, specificity: 97-89 %, area under the curve: 0.79-0.92, p = 0.018). Multivariate logistic regression analysis indicated that TWAaVR and BBB were independent electrocardiography parameters associated with CI. In summary, we observed that sarcoidosis patients exhibiting a high TWAaVR were likely to have CI. Thus, the application of a combination of BBB with TWAaVR may be useful when screening for CI in sarcoidosis patients.

    Full Text Available In this study, we sought to identify differentially expressed proteins in the serum of patients with sarcoidosis or tuberculosis and to evaluate these proteins as markers for the differential diagnosis of sarcoidosis and sputum-negative tuberculosis.Using protein microarrays, we identified 3 proteins exhibiting differential expression between patients with sarcoidosis and tuberculosis. Elevated expression of these proteins was verified using the enzyme-linked immunosorbent assay (ELISA and was further confirmed by immunohistochemistry. Receiver operating characteristic (ROC curve, logistic regression analysis, parallel, and serial tests were used to evaluate the diagnostic efficacy of the proteins.Intercellular Adhesion Molecule 1(ICAM-1 and leptin were screened for differentially expressed proteins relevant to sarcoidosis and tuberculosis. Using ROC curves, we found that ICAM-1 (cutoff value: 57740 pg/mL had an area under the curve (AUC, sensitivity, and specificity of 0.718, 62.3%, and 79.5% respectively, while leptin (cutoff value: 1193.186 pg/mL had an AUC, sensitivity, and specificity of 0.763, 88.3%, and 65.8%, respectively. Logistic regression analysis revealed that the AUC, sensitivity, and specificity of combined leptin and ICAM-1 were 0.787, 89.6%, and 65.8%, respectively, while those of combined leptin, ICAM-1, and body mass index (BMI were 0.837, 90.9%, and 64.4%, respectively, which had the greatest diagnostic value. Parallel and serial tests indicated that the BMI-leptin parallel with the ICAM-1 serial was the best diagnostic method, achieving a sensitivity and specificity of 86.5% and 73.1%, respectively. Thus, our results identified elevated expression of ICAM-1 and leptin in serum and granulomas of sarcoidosis patients.ICAM-1 and leptin were found to be potential markers for the diagnosis of sarcoidosis and differential diagnosis of sarcoidosis and sputum-negative tuberculosis.

    Sarcoidosis is a multiorgan granulomatous disease of unknown etiology that primarily involves the lungs and the lymphatic system. Extrapulmonary sarcoidosis is common, occurring in 30 to 50% of patients. In this review, we describe and illustrate the role of F-FDG PET/CT and MR imaging in patients with extrapulmonary sarcoidosis. FDG-PET/CT and MR can improve the accuracy of the diagnosis of extrapulmonary involvement, specify the respective contributions of active and fibrotic components of lesions, guide the selection of the biopsy site, provide prognostic information, and guide therapeutic management. We focus on suggestive patterns that help to improve lesion characterization, especially when these lesions are clinically occult. In cardiac sarcoidosis, the combined use of FDG-PET/CT and cardiac MR may provide optimal detection of the disease by enabling the differentiation between patients with active granulomatous inflammation and those with fibrous lesions. In cases with central nervous system involvement, the T2 hypointensity of the dural and parenchymal lesions is helpful for identifying sarcoidosis. Granulomatous bone marrow infiltration in the axial skeleton can be sensitively detected by both FDG-PET/CT and MR. Muscular sarcoidosis can have a characteristic appearance with the "dark star" sign on MR and a thick linear FDG uptake that predominantly involves the lower legs, designated as the "tiger man" sign. Extrathoracic lymphadenopathy is commonly observed on FDG-PET/CT imaging; however, its features are not specific, and the differentiation of extrathoracic lymphadenopathy from metastatic disease, tuberculosis, or lymphoma may be difficult. Familiarity with the functional imaging features in extrapulmonary sarcoidosis in various anatomical locations plays a crucial role in the diagnosis and management of patients.

    Sarcoidosis is a multisystem disease that commonly affects the lung, eye, skin, and lymphatic systems. Organ function has been a major focus of treatment outcome with less attention given to more subjective impacts, such as health-related quality of life (HRQL). The purpose of this paper is to present a conceptual model of HRQL in sarcoidosis, which was developed through patient and clinician input. We surveyed sarcoidosis clinical experts (n = 5) regarding disease-specific symptoms and their impact on their patient's lives. We also conducted three sarcoidosis patient focus groups (n = 22) that reflected major sarcoidosis typologies (lung, skin, and eye). Data were coded and summarized using qualitative methodologies. Clinicians highlighted the following domains as being important (relative frequencies for comments are in parentheses): emotional distress (17%), lung problems (14%), pain (14%), physical limitations (14%), fatigue (10%), social limitations (10%), eye problems (7%), skin problems (7%), sleep disturbance (3%), and constitutional symptoms (3%). Similarly, patients highlighted the following domains: social limitations (14%), skin problems (12%), pain (10%), coping (10%), emotional distress (9%), lung problems (8%), eye problems (7%), negative impact of corticosteroids (7%), physical limitations (6%), fatigue (6%), sleep disturbance (3%), constitutional symptoms (2%), comorbidities (2%), other systems affected (2%), environmental factors (1%), and positive impact of corticosteroids (1%). Clinician and patient responses overlapped in several domains, including emotional distress, physical and social limitations, and sarcoidosis-specific impacts, such as eye, skin, and lung problems. These findings support the HRQL impact of sarcoidosis and provide the basis for a conceptual model which has the potential to inform new patient-reported outcomes measures for this population.

    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.

    Sarcoidosis is considered an idiopathic granulomatous disease, although similar immunological and clinical features with tuberculosis (TB) suggest mycobacterial involvement in its pathogenesis. High-content peptide microarrays (HCPM) may help to decipher mycobacteria-specific antibody reactivity in sarcoidosis. Serum samples from patients with sarcoidosis, Löfgren's syndrome, and TB, as well as from healthy individuals (12/group), were tested on HCPM containing 5964 individual peptides spanning 154 Mycobacterium tuberculosis proteins displayed as 15-amino acid stretches. Inclusion/exclusion and significance analyses were performed according to published methods. Each study group recognized 68-78% M. tuberculosis peptides at least once. M. tuberculosis epitope recognition by sarcoidosis patient sera was 42.7%, and by TB patient sera was 39.1%. Seven and 16 peptides were recognized in 9/12 (75%) and 8/12 (67%) sarcoidosis patient sera but not in TB patient sera, respectively. Nine (75%) and eight (67%) out of twelve TB patient sera, respectively recognized M. tuberculosis peptides that were not recognized in sarcoidosis patient sera. Specific IgG recognition patterns for M. tuberculosis antigens in sarcoidosis patients re-affirm mycobacterial involvement in sarcoidosis, providing biologically relevant targets for future studies pertaining to diagnostics and immunotherapy.

    Conclusion: TRACP5a protein is expressed abundantly in the granulomatous tissues and may be elevated in a significant proportion of sarcoidosis patients. These findings further support our hypothesis that serum TRACP5a is derived from systemic inflammatory MΦ and thereby may be a biomarker of inflammation for sarcoidosis and also reflect its disease activity.

    Full Text Available Background: Sarcoidosis is a systemic granulomatosis commonly affecting respiratory system. Variable and often unpredictable flow of the disease provides rationale for the development of prognostic algorithm. Aim: To detect predictive parameters in pulmonary and thoracic lymph nodes sarcoidosis; to develop prognostic algorithm. Materials and methods: The results of examination of 113 patients (85 women and 28 men, 19–77 years old with morphologically verified sarcoidosis has been assessed. Clinical manifestations, functional, radiographic (including CT numerical scores and morphological features of the disease were analyzed against 3-year outcomes in prednisolon/hydroxychloroquine-treated or treatment-naive patients. Results: Radiographic stage, CT-pattern scores, several parameters of pulmonary function tests (DLCO, RV, FEV1, FVC and dyspnoe had the greatest prognostic significance for disease flow. Prognostic accuracy was 87.8% and increased to 94.5% after one-year dynamics of symptoms was taken into account. Therapy with systemic glucocorticosteroids did not influence outcomes in sarcoidosis with asymptomatic enlargement of thoracic lymph nodes. Conclusion: We have developed an algorithm for prognosis assessment in pulmonary sarcoidosis. Taking into account the results of patients follow-up significantly improves the accuracy of the prognosis.

  9. Local and Systemic CD4+ T Cell Exhaustion Reverses with Clinical Resolution of Pulmonary Sarcoidosis

    2017-01-01

    Full Text Available Investigation of the Th1 immune response in sarcoidosis CD4+ T cells has revealed reduced proliferative capacity and cytokine expression upon TCR stimulation. In other disease models, such cellular dysfunction has been associated with a step-wise, progressive loss of T cell function that results from chronic antigenic stimulation. T cell exhaustion is defined by decreased cytokine production upon TCR activation, decreased proliferation, increased expression of inhibitory cell surface receptors, and increased susceptibility to apoptosis. We characterized sarcoidosis CD4+ T cell immune function in systemic and local environments among subjects undergoing disease progression compared to those experiencing disease resolution. Spontaneous and TCR-stimulated Th1 cytokine expression and proliferation assays were performed in 53 sarcoidosis subjects and 30 healthy controls. PD-1 expression and apoptosis were assessed by flow cytometry. Compared to healthy controls, sarcoidosis CD4+ T cells demonstrated reductions in Th1 cytokine expression, proliferative capacity (p<0.05, enhanced apoptosis (p<0.01, and increased PD-1 expression (p<0.001. BAL-derived CD4+ T cells also demonstrated multiple facets of T cell exhaustion (p<0.05. Reversal of CD4+ T cell exhaustion was observed in subjects undergoing spontaneous resolution (p<0.05. Sarcoidosis CD4+ T cells exhibit loss of cellular function during progressive disease that follows the archetype of T cell exhaustion.

    Cardiac sarcoidosis (CS) is associated with high morbidity and sudden death. The absence of specific symptoms and lack of diagnostic gold standard technique is challenging. New imaging methods could improve the diagnosis of CS. The aim of our study was to assess the role of left ventricular (LV) longitudinal and circumferential strain as estimated by 2D speckle-tracking imaging in patients with diagnosed sarcoidosis without cardiac involvement according to the current guidelines. We investigated the prevalence of LV strain impairment in this population and assessed its relationship with clinical outcomes, composite of mortality, heart failure, arrhythmia and/or secondarily development of CS and cardiac device implantation. We performed a prospective case-control longitudinal study including 35 patients with diagnosed sarcoidosis and normal cardiac function as assessed by standard transthoracic echocardiography and 35 healthy age- and gender-matched controls. All patients underwent a comprehensive echocardiographic study. Mean age of patients was 47.9±14.8years old (22 women). Compared with controls, global LV longitudinal strain (LV GLS) was reduced in sarcoidosis patients: (-17.2±3.1 vs -21.3±1.5%, psarcoidosis patients that was associated with outcomes. LV GLS may represent an early marker of myocardial involvement in sarcoidosis patients that needs to be studied further. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    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.

    To determine inter-rater reliability of sarcoidosis-related computed tomography (CT) findings that can be used for scoring of thoracic sarcoidosis. CT images of 51 patients with sarcoidosis were scored by five chest radiologists for various abnormal CT findings (22 in total) encountered in thoracic sarcoidosis. Using intra-class correlation coefficient (ICC) analysis, inter-rater reliability was analysed and reported according to the Guidelines for Reporting Reliability and Agreement Studies (GRRAS) criteria. A pre-specified sub-analysis was performed to investigate the effect of training. Scoring was trained in a distinct set of 15 scans in which all abnormal CT findings were represented. Median age of the 51 patients (36 men, 70 %) was 43 years (range 26 - 64 years). All radiographic stages were present in this group. ICC ranged from 0.91 for honeycombing to 0.11 for nodular margin (sharp versus ill-defined). The ICC was above 0.60 in 13 of the 22 abnormal findings. Sub-analysis for the best-trained observers demonstrated an ICC improvement for all abnormal findings and values above 0.60 for 16 of the 22 abnormalities. In our cohort, reliability between raters was acceptable for 16 thoracic sarcoidosis-related abnormal CT findings. (orig.)

    Core-needle biopsy guided by ultrasound can be performed for investigating peripheral lymph node (PLN). The aim of this study was to determine the efficacy of this technique in sarcoidosis. Retrospective review of files of all patients in the database of the radiology department of Avicenne university hospital who underwent PLN biopsies guided by ultrasound from January 2008 to June 2011 (n=292). Cases with either granulomas at histology with the procedure or with a final diagnosis of sarcoidosis were included in the study. The histological specimens were adequate in 282 out of 292 cases (96%) showing non-caseating granulomas in 22 cases (n=20 patients with a final diagnosis of sarcoidosis and n=2 patients with tuberculosis). After reviewing clinical files of the 282 patient, 22 were confirmed to have sarcoidosis, at initial presentation (n=19) or later during flare-up or relapse (n=3) with only 2 patients having no granuloma on PLN biopsy. PLN were palpable in 18 cases and only detected by (18F)FDG-PET/CT showing increased PLN uptake in 4 cases. The sensitivity and specificity of adequate biopsy were 91 and 99% and the positive and negative predictive values were 91 and 99%, respectively. Core-needle biopsy guided by ultrasound has a high efficacy for evidencing granulomas in sarcoidosis patients with PLN involvement either clinically palpable or in the presence of (18F)FDG-PET/CT uptake.

    For patients with sarcoidosis, no consensus exists about the management of osteoporosis, whether related or unrelated to glucocorticoid therapy. We report the first series of 4patients with histologically documented sarcoidosis who received teriparatide therapy for severe osteoporosis manifesting as a fracture cascade with multilevel vertebral fractures. When teriparatide was started, 1patient was receiving 10mg of prednisone equivalents per day, 1 was progressively tapering glucocorticoid dose, 2 had never received any glucocorticoid treatment. In all 4patients, teriparatide was effective in halting the fracture cascade, including in the 2patients who remained on long-term glucocorticoid therapy. None of the patients developed hypercalcemia. During teriparatide therapy, 3patients underwent a flare or a complication of sarcoidosis. Only the patient on stable glucocorticoid treatment did not present any adverse event. Before teriparatide initiation, sarcoidosis had been well controlled in all 3patients for several years. Even if the implication of teriparatide is unclear, the appearance of adverse events in 3 out of 4patients in this small series suggest caution in the use of teriparatide in patients with sarcoidosis.

    Full Text Available Objective To improve the ability of clinicians in the recognition, diagnosis and treatment of sarcoidosis with renal damage through analyzing the clinical data of one case of sarcoidosis with renal damage and literature review. Methods One case of sarcoidosis with renal damage was reported. The case history, clinical manifestations, pathological features, diagnosis and treatment of the patient were analyzed, and the related literature published domestically and abroad was reviewed to summarize the experiences in diagnosis and treatment of the disease. Results The patient was a 39 years old woman. The primary main clinical manifestations were cough and fever. Renal damage manifesting proteinuria and microscopic hematuria appeared one month later, and chest CT showed mediastinum and bilateral hilar lymphadenectasis. Renal and tracheal mucosa biopsy revealed noncaseating necrotized granuloma, so the diagnosis of sarcoidosis with renal damage was confirmed. Administration of glucocorticoid combined with cyclophosphamide achieved good therapeutic effect: hypercalciuria and proteinuria that lymph nodes in were abated with urinary calcium and protein returned to normal level, and microscopic hematuria disappeared. Chest CT showed mediastinum and hilum on both sides reduced significantly in size compared with those before the treatment. Conclusion  Sarcoidosis with renal damage is a rare disease with atypical clinical manifestations. Early diagnosis and timely treatment may achieve good effects.

    Background Ocular infestation with Toxoplasma gondii, a parasite, may result in inflammation in the retina, choroid, and uvea and consequently lead to complications such as glaucoma, cataract, and posterior synechiae. Objectives The objective of this systematic review was to assess the effects of adjunctive use of corticosteroids for ocular toxoplasmosis. Search methods We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2012, Issue 9), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE, (January 1950 to October 2012), EMBASE (January 1980 to October 2012), Latin American and Caribbean Literature on Health Sciences (LILACS) (January 1982 to October 2012), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We searched the reference lists of included studies for any additional studies not identified by the electronic searches. We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 11 October 2012.

    Full Text Available IntroductionThe purpose of this article is to examine the emerging role of whole-body positron emission tomography (PET with 18F-fluorodeoxyglucose (FDG in patients with sarcoidosis.Materials and methodsWe reviewed the literature on the use of FDG-PET in patients with sarcoidosis to identify how this technique is being applied in clinical practice.Results and discussionOur review shows that: 1 sarcoidosis is commonly associated with increased FDG uptake. Therefore, positive findings should be interpreted with caution when FDG-PET is being used to distinguish benign from malignant abnormalities; 2 FDG-PET seems to be a very useful molecular imaging method for staging sarcoidosis, identification of occult sites of involvement, guiding biopsy procedures, and monitoring patients’ responses to treatment; and 3 in patients with sarcoidosis, the diagnostic accuracy of FDG-PET is superior to that of 67Ga scintigraphy.

    To present a novel case of ocular argyrosis mimicking conjunctival melanoma. A 48-year-old man who is a jewelry manufacturer presented with raised pigmented lesions in the inferior fornices of both eyes. Brown-black colored, follicle-like, masses were observed in both fornices. An incisional biopsy confirmed the presence of silver and the diagnosis of ocular argyrosis. Despite its limited negative health effects, ocular argyrosis should be considered in the differential diagnosis of conjunctival pigmented lesions because of the potential for misidentification of neoplastic growth.

    questions asked to the patient and the analysis of the clinical picture, it was suspected that the patient was affected by myasthenia gravis, and then he was referred to the clinician and the neurologist. The studies based on the neuroimaging analysis, the tomography and the electroencephalogram did not show any alteration. It was decided to evaluate the case with the assistance of the neurophthalmology service in our center and the Institute of Neurology; the diagnosis was confirmed.

    Sarcoidosis is, from historical data, suggested to be more prevalent among patients with tattoo reactions. We aimed to evaluate this association in a systematic study. This is a consecutive study of patients with tattoo complications, diagnosed in the "Tattoo Clinic" at Bispebjerg University Hospital in Copenhagen, Denmark, from 2008 to 2015, based on clinical assessment and histology. From the overall group of 494 tattoo complications in 406 patients, 92 reactions in 72 patients showed a papulo-nodular pattern studied for local and systemic sarcoidosis, since sarcoidosis is expected to be nodular. Of the 92 reactions with a papulo-nodular pattern, 27 (29%) reactions in 19 patients were diagnosed as cutaneous or systemic sarcoidosis, supported by histology; 65 (71%) were diagnosed as non-sarcoidosis due to histology and no clinical sarcoid manifestations. "Rush phenomenon" with concomitant reaction in many other black tattoos, triggered by a recent tattoo with a papulo-nodular reaction, was observed in 70% in the sarcoidosis group and 28% in the non-sarcoidosis group, indicating a predisposing factor which may be autoimmune and linked with sarcoidosis. Agglomerates of black pigment forming foreign bodies may in the predisposed individual trigger widespread reaction in the skin and internal organs. Black tattoos with papulo-nodular reactions should be seen as markers of sarcoidosis. Papulo-nodular reactions may, as triggers, induce widespread reactions in other black tattoos - a "rush phenomenon" - depending on individual predisposition. Sarcoidosis is estimated to be 500-fold increased in papulo-nodular reactions compared to the prevalence in the general population, and the association with black tattoos is strong. © 2017 S.

    Sarcoidosis is a multisystemic disorder of unknown etiology, characterised by the presence of non-caseating granulomas in target organs. In ninety percent of cases, there is thoracic involvement. Fifty to seventy percent of pulmonary sarcoidosis patients will experience acute, self-limiting disease. For the subgroup of patients who develop persistent disease, no targeted therapy is currently available. To investigate the potential of the single nucleotide polymorphism (SNP), Toll-like receptor 3 Leu412Phe (TLR3 L412F; rs3775291), as a causative factor in the development of, and in disease persistence in pulmonary sarcoidosis. To investigate the functionality of TLR3 L412F in vitro in primary human lung fibroblasts from pulmonary sarcoidosis patients. Cohorts of Irish sarcoidosis patients (n = 228), healthy Irish controls (n = 263) and a secondary cohort of American sarcoidosis patients (n = 123) were genotyped for TLR3 L412F. Additionally, the effect of TLR3 L412F in primary lung fibroblasts from pulmonary sarcoidosis patients was quantitated following TLR3 activation in the context of cytokine and type I interferon production, TLR3 expression, and apoptotic- and fibroproliferative-responses. We report a significant association between TLR3 L412F and persistent clinical disease in two cohorts of Irish and American Caucasians with pulmonary sarcoidosis. Furthermore, activation of TLR3 in primary lung fibroblasts from 412F-homozygous pulmonary sarcoidosis patients resulted in reduced IFN-β and TLR3 expression, reduced apoptosis- and dysregulated fibroproliferative-responses compared with TLR3 wild-type patients. This study identifies defective TLR3 function as a previously unidentified factor in persistent clinical disease in pulmonary sarcoidosis and reveals TLR3 L412F as a candidate biomarker.

  2. Ocular Blood Flow Autoregulation Mechanisms and Methods

    Full Text Available The main function of ocular blood flow is to supply sufficient oxygen and nutrients to the eye. Local blood vessels resistance regulates overall blood distribution to the eye and can vary rapidly over time depending on ocular need. Under normal conditions, the relation between blood flow and perfusion pressure in the eye is autoregulated. Basically, autoregulation is a capacity to maintain a relatively constant level of blood flow in the presence of changes in ocular perfusion pressure and varied metabolic demand. In addition, ocular blood flow dysregulation has been demonstrated as an independent risk factor to many ocular diseases. For instance, ocular perfusion pressure plays key role in the progression of retinopathy such as glaucoma and diabetic retinopathy. In this review, different direct and indirect techniques to measure ocular blood flow and the effect of myogenic and neurogenic mechanisms on ocular blood flow are discussed. Moreover, ocular blood flow regulation in ocular disease will be described.

  3. Electrophysiological Features of Atrial Flutter in Cardiac Sarcoidosis: A Report of Two Cases

    2012-11-01

    Full Text Available We report two cases of systemic sarcoidosis with atrial flutter as the clinical manifestation. In one patient, who had symptoms of shorter duration, the arrhythmia was no longer inducible after a course of glucocorticoid therapy. Electroanatomical mapping in the other case revealed patchy fibrosis of the left atrial myocardium and multiple macro-reentrant circuits. Sinus rhythm could be restored with ablation of these reentrant circuits. To our knowledge, this is the first report on the demonstration of atrial scarring in a patient with sarcoidosis using 3-D electroanatomical mapping. These two cases illustrate that the inflammation of atrial myocardium is the primary mechanism of atrial arrhythmias in patients with cardiac sarcoidosis.

    Alveolar macrophages differ from their percursors in blood, monocytes, by expressing strong activity of the tartrate resistant variant of acid phosphatase (TAcP). A study was carried out to analyse the expression of this enzyme cytochemical marker by alveolar macrophages from bronchoalveolar lavage cells from 34 patients with sarcoidosis and 12 control subjects. Alveolar macrophages from control subjects displayed a strong and homogeneous staining pattern and only 0.1% of cells were negative after staining. Macrophages from patients with sarcoidosis showed reduced TAcP activity and up to 7% of the cells were negative. The percentage of TAcP negative macrophages was correlated with the percentage of lymphocytes and with the ratio of CD4 to CD8 lymphocytes among cells recovered by bronchoalveolar lavage. The reduced TAcP activity in alveolar macrophages from patients with sarcoidosis may be due to an increased recruitment of immature precursors from blood.

    The occurrence of a sarcoidosis associated with Hodgkin's disease is an infrequent but well-described event. Moreover it has been described for many decades that some malignancies may present with simultaneous granulomatous manifestations named sarcoid-like reactions. To differentiate sarcoidosis from the sarcoid-like reactions is not an easy step in the final diagnosis. No author in the past has included the use of 2-deoxy-2[18F]fluoro-D-glucose positron emission tomography (FDG-PET) in order to help in this differentiation. We report two patients with Hodgkin's disease complicated with a typical form of sarcoidosis and with diffuse sarcoid-like reactions. We discuss the use of FDG-PET as a tool in the making of the final diagnosis and the difficulties associated with this technique in the interpretation of different hypermetabolic tissues.

  6. Genotyping in the MHC locus: potential for defining predictive markers in sarcoidosis

    2001-10-01

    Full Text Available Abstract In sarcoidosis, host genetic factors are discussed as contributing to disease susceptibility and course. Since tumor necrosis factor (TNF-α is a central mediator of granuloma formation and since elevated TNF-α levels are found during active phases of sarcoidosis, genetic polymorphisms correlating with influences on TNF-α levels are of special interest. The complete sequencing of the MHC region and the increase in the number of identified gene polymorphisms in this locus associated with TNF-α production offer the opportunity of detecting new genes associated with sarcoidosis and perhaps of defining disease-associated haplotypes that bear the potential of serving as predictive markers for this disease.

    Full Text Available Sarcoidosis is a chronic multisystemic granulomatous disease that is triggered by an autoimmune process. Nowadays, this pathology represents a well-recognized but uncommon complication for antiviral treatment in hepatitis C virus (HCV infection. Herein, we report a remarkable case of 47-year-old woman treated for chronic HCV infection; the patient has developed interferon alfa-induced sarcoidosis involving the central nervous system. The evolution was fatal despite disrupting the antiviral therapy and initiating a high-dose corticotherapy. This complication of interferon alfa treatment was reported in the literature in only one case. Through this case and a review of the literature, we aim to underline the importance of screening for sarcoidosis before and during the follow-up of HCV patients undergoing antiviral therapy.

    Full Text Available Sarcoidosis is an inflammatory disease that affects mostly the lungs and lymph glands. Renal involvement is rare and especially vasculitis. We report a case who presented an acute kidney failure and had sarcoidosis with vasculitis and nodular splenic involvement. A 35-year-old woman presenting a Lofgren syndrome was hospitalized for acute renal failure with cervical lymphadenopathy without other clinical findings. Laboratory data disclosed elevated angiotensin converting enzyme serum level. Abdominal ultrasound showed a multinodular spleen. Renal histology revealed granulomatous interstitial nephritis with necrotizing vasculitis. Outcome was favorable after the institution of high dose corticosteroids along with cyclophosphamide. Renal involvement is rare in sarcoidosis. However, the diagnostic delay should be avoided to improve the outcome.

    Full Text Available Thoracic sarcoidosis is a common disease, with well-described and recognizable radiographic features. Nevertheless, most physicians are not familiar with the rare atypical often-confusing manifestations of thoracic sarcoid. Although these findings have been previously reviewed, but more recent advances in imaging and laboratory science, need to be incorporated. We present a review of literature and illustrate the review with unpublished data, intended to provide a more recent single comprehensive reference to assist with the diagnosis when atypical radiographic findings of thoracic sarcoidosis are encountered. Thoracic involvement accounts for most of morbidity and mortality associated with sarcoidosis. An accurate timely identification is required to minimize morbidity and mortality. It is essential to recognize atypical imaging findings and relate these to clinical manifestations and histology.

    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.

  11. Genetic Variation in Osteopontin Gene Is Associated with Susceptibility to Sarcoidosis in Slovenian Population

    Full Text Available Sarcoidosis is a systemic inflammatory disease characterised by appearance of granulomas. Precise etiology has not been elucidated. Osteopontin (Opn is a Th1 cytokine whose levels have been found increased in granulomas and serum samples from patients with sarcoidosis. We investigated whether genetic variation in Osteopontin gene (OPN gene contributes to susceptibility to sarcoidosis. Haplotype-block structure in the OPN gene region was investigated using data from HapMap project. Three representative SNPs have been selected from each block of SNPs in linkage disequilibrium (rs11730582-C/T, rs11728697-C/T and rs4754-C/T. Genotyping was performed using TaqMan SNP Genotyping Assays on a sample of 165 patients and 284 controls. Statistical analyses of association were performed using Chi-Square test and algorithms implemented in the haplo.stats and PHASE packages. Genotyping analysis revealed a significant difference in genotype frequencies at rs4754 polymorphism in groups of patients and controls under recessive genetic model (p=0.036, OR=1.99, 95%CI=1.04-3.82, CC homozygotes being significantly over-represented in the patients group. However these results failed to reach significance after correction for multiple testing (p=0.25. The frequencies of predicted haplotypes differed between patient and control groups, frequency of TTT haplotype was found to be significantly decreased in the group of patients with sarcoidosis (p=0.014, OR=0.40, 95%CI=0.20-0.79. Our results suggest that variation in the OPN gene might be significantly associated with sarcoidosis and that the TTT haplotype in OPN may act as a protective factor in sarcoidosis.

    Sarcoidosis is a systemic autoimmune disease where an inflammatory reaction involving alveolar macrophages, T-helper lymphocytes, and epitheloid cells is mounted against unknown antigens. A genetic predisposition for sarcoidosis is supposed by studies in twins, by geographical and racial distribution. In the current investigation we compared the expression patterns between slow onset and acute sarcodosis using a whole-genome cDNA array. Bronchoalveolar lavage was performed in six patients with slow onset sarcoidosis and four patients with acute sarcoidosis (Löfgren's disease) and obtained cells were used for gene expression profiling. The results were confirmed by RT- and Taqman-PCR. In addition, protein expression was examined on paraffin sections of sarcoid granulomas by immunohistochemistry. In T-helper lymphocytes and alveolar macrophages we found an upregulation of genes belonging to the phosphoinositol-3-kinase/v-akt murine thymoma viral oncogene homolog/signal transducer and activator of transcription 3 pathway, as well as a downregulation of genes of the extrinsic and intrinsic apoptotic signaling cascades. In addition an upregulation of the genes encoding fatty acid binding protein 4 and 5, as well as peroxisome proliferative activated receptor delta in Löfgren's disease was detected. Differences in gene expression between slow onset sarcoidosis and Löfgren's syndrome were found mainly within genes of the major histocompatibility complex. In sarcoidosis enhanced cell proliferation and decreased apoptosis result in accumulation and prolonged survival of antigen-primed T-helper lymphocytes and activated macrophages. This is enhanced in Löfgren's disease, probably by hyper-stimulation via the peroxisome proliferation signaling, providing a larger pool of antigen-primed immune cells.

    Pulmonary sarcoidosis (PS) is characterized by the formation of granulomas in the lungs and has been associated with infection by microorganisms. Triggering receptor expressed on the surface of myeloid cells (TREM)-1 is overexpressed in response to infection while TREM-2 is involved in granuloma formation. We hypothesized that these receptors are overexpressed in PS and might be useful for diagnostic testing. Cell surface TREM-1 and TREM-2 expression in cells obtained at bronchoalveolar lavage (BAL) was measured in individuals with sarcoidosis (n = 26) and compared with that seen in individuals with other interstitial lung diseases (ILD) (n = 27). TREM-1 and TREM-2 expression was significantly increased in sarcoidosis compared with other ILD: total number of TREM-1, P = 0.0039 (23.81 vs 13.50 cells/μl), TREM-2, P < 0.0001 (32.81 vs 7.76 cells/μl); percentage of TREM-1: P = 0.0002 (41.30% vs 15.70%), TREM-2: P < 0.0001 (34% vs 9.60%); and mean fluorescence of TREM-1: P = 0.0005 (5.43 vs 1.96), TREM-2: P = 0.0011 (6.85 vs 2.77). Increase in both of these receptors seems to be typical for PS. In discriminating sarcoidosis from other ILD, the specificity (96%) and sensitivity (72%) of the combination of TREM-1 and TREM-2 was high. Increased TREM-1 and TREM-2 cell surface expression is observed in sarcoidosis. Evaluation of BAL cell expression of both of these receptors may serve as a diagnostic marker for sarcoidosis. © 2013 The Authors. Respirology © 2013 Asian Pacific Society of Respirology.

    Full Text Available Abstract Background There is increasing evidence that exposure to moulds (fungi may influence the development of sarcoidosis. To assess the influence of the environmental exposure, a study was undertaken to determine the exposure to fungi in homes of subjects with sarcoidosis. Methods Subjects were patients with clinically established sarcoidosis recruited during the period September 2007 till June 2010. Of these 55 were newly diagnosed and currently under treatment for less than one year, 25 had been treated and had no recurrence and 27 had been treated but had recurrence of the disease. Controls were healthy subjects without any respiratory symptoms (n = 30. Samples of air (about 2.5 m3 were taken in the bedroom of the subjects using a portable pump and cellulose ester filters. The filters were analysed for the content of the enzyme N-acetylhexosaminidase (NAHA as a marker of fungal cell biomass, using a specific substrate and a fluorescent technique and expressed as NAHA units (U/m3. Results Compared to controls, subjects undergoing treatment of the disease (newly diagnosed or with recurrence had significantly higher activities of NAHA in their homes than controls (33.6 and 39.9 vs 10.0 U/m3, p 3. In homes of subjects with newly diagnosed disease with treatment less than one year, values above 14 NAHA U/m3 were found among 35 out of 55 and among those with recurrent disease among 18 out of 27. Conclusions The higher activities of NAHA enzyme found in homes of subjects with active and recurrent sarcoidosis suggest that exposure to fungi is related to the risk of sarcoidosis. Further environmental studies to assess the importance of this exposure for subjects with sarcoidosis are warranted. The results suggest that remedial actions in homes with high levels of fungi may be justified.

  15. An in silico modeling approach to understanding the dynamics of sarcoidosis.

    Directory of Open Access Journals (Sweden)

    Baltazar D Aguda

    Full Text Available BACKGROUND: Sarcoidosis is a polygenic disease with diverse phenotypic presentations characterized by an abnormal antigen-mediated Th1 type immune response. At present, progress towards understanding sarcoidosis disease mechanisms and the development of novel treatments is limited by constraints attendant to conducting human research in a rare disease in the absence of relevant animal models. We sought to develop a computational model to enhance our understanding of the pathological mechanisms of and predict potential treatments of sarcoidosis. METHODOLOGY/RESULTS: Based upon the literature, we developed a computational model of known interactions between essential immune cells (antigen-presenting macrophages, effector and regulatory T cells and cytokine mediators (IL-2, TNFα, IFNγ of granulomatous inflammation during sarcoidosis. The dynamics of these interactions are described by a set of ordinary differential equations. The model predicts bistable switching behavior which is consistent with normal (self-limited and "sarcoidosis-like" (sustained activation of the inflammatory components of the system following a single antigen challenge. By perturbing the influence of model components using inhibitors of the cytokine mediators, distinct clinically relevant disease phenotypes were represented. Finally, the model was shown to be useful for pre-clinical testing of therapies based upon molecular targets and dose-effect relationships. CONCLUSIONS/SIGNIFICANCE: Our work illustrates a dynamic computer simulation of granulomatous inflammation scenarios that is useful for the investigation of disease mechanisms and for pre-clinical therapeutic testing. In lieu of relevant in vitro or animal surrogates, our model may provide for the screening of potential therapies for specific sarcoidosis disease phenotypes in advance of expensive clinical trials.

    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.

    Blau syndrome (BS) and early onset sarcoidosis (EOS) are, respectively, the familial and sporadic forms of the pediatric granulomatous autoinflammatory disease, which belong to the group of monogenic autoinflammatory syndromes. Both of these conditions are caused by mutations in the NOD2 gene, which encodes the cytosolic NOD2 protein, one of the pivotal molecules in the regulation of innate immunity, primarily expressed in the antigen-presenting cells. Clinical onset of BS and EOS is usually in the first years of life with noncaseating epithelioid granulomas mainly affecting joints, skin, and uveal tract, variably associated with heterogeneous systemic features. The dividing line between autoinflammatory and autoimmune mechanisms is probably not so clear-cut, and the relationship existing between BS or EOS and autoimmune phenomena remains unclear. There is no established therapy for the management of BS and EOS, and the main treatment aim is to prevent ocular manifestations entailing the risk of potential blindness and to avoid joint deformities. Nonsteroidal anti-inflammatory drugs, corticosteroids and immunosuppressive drugs, such as methotrexate or azathioprine, may be helpful; when patients are unresponsive to the combination of corticosteroids and immunosuppressant agents, the tumor necrosis factor-α inhibitor infliximab should be considered. Data on anti-interleukin-1 inhibition with anakinra and canakinumab is still limited and further corroboration is required. The aim of this paper is to describe BS and EOS, focusing on their genetic, clinical, and therapeutic issues, with the ultimate goal of increasing clinicians' awareness of both of these rare but serious disorders.

    Early-onset sarcoidosis (EOS), which occurs in children younger than 5 years of age, is associated with granulomatous lesions and a sporadic genetic mutation of the nucleotide-binding oligomerization domain 2 that causes constitutive NF-kappaB activation. The symptoms of EOS can be uncontrollable, progressive, and associated with profound complications. However, appropriate therapy is still under investigation. The aim of this study was to assess the efficacy of thalidomide in patients with severe EOS, based on etiology supporting an initial role of NF-kappaB in activation of this disease. Thalidomide was given to 2 patients with EOS (a 16-year-old girl and an 8-year-old boy) at an initial dosage of 2 mg/kg/day, and the dosage was increased if necessary. To elucidate the mechanism of the drug, peripheral blood monocytes were isolated from the patients and stimulated with cytokines (macrophage colony-stimulating factor, tumor necrosis factor alpha, and interleukin-4), and their ability to form multinucleated giant cells (MGCs) and osteoclasts was measured. Both patients showed dramatic improvement of their clinical symptoms (alleviation of fever and optic nerve papillitis, achievement of a response according to the American College of Rheumatology Pediatric 50 and Pediatric 70 criteria) and laboratory findings. Monocytes from patients with EOS had a greater ability to survive and induce MGCs and osteoclasts than those from healthy control subjects. The formation of MGCs and osteoclasts was inhibited by the presence of thalidomide. The ability of thalidomide to improve clinical symptoms and laboratory findings in patients with EOS indicates a central role for NF-kappaB activity in this disorder. Inhibition of IKK might be a pharmacologic action by which thalidomide down-regulates NF-kappaB signaling. Thalidomide may be an effective medication in patients with severe complications of EOS, including ocular involvement.

    Blau syndrome and its sporadic counterpart, early-onset sarcoidosis (EOS), share a phenotype featuring the symptom triad of skin rash, arthritis, and uveitis. This systemic inflammatory granulomatosis is associated with mutations in the NOD2 gene. The aim of this study was to describe the clinical manifestations of Blau syndrome/EOS in Japanese patients and to determine whether the NOD2 genotype and its associated basal NF-kappaB activity predict the Blau syndrome/EOS clinical phenotype. Twenty Japanese patients with Blau syndrome/EOS and NOD2 mutations were recruited. Mutated NOD2 was categorized based on its basal NF-kappaB activity, which was defined as the ratio of NF-kappaB activity without a NOD2 ligand, muramyldipeptide, to NF-kappaB activity with muramyldipeptide. All 9 mutations, including E383G, a novel mutation that was identified in 20 patients with Blau syndrome/EOS, were detected in the centrally located NOD region and were associated with ligand-independent NF-kappaB activation. The median age of the patients at disease onset was 14 months, although in 2 patients in Blau syndrome families (with mutations R334W and E383G, respectively) the age at onset was 5 years or older. Most patients with Blau syndrome/EOS had the triad of skin, joint, and ocular symptoms, the onset of which was in this order. Clinical manifestations varied even among familial cases and patients with the same mutations. There was no clear relationship between the clinical phenotype and basal NF-kappaB activity due to mutated NOD2. However, when attention was focused on the 2 most frequent mutations, R334W and R334Q, R334W tended to cause more obvious visual impairment. NOD2 genotyping may help predict disease progression in patients with Blau syndrome/EOS.

    Ocular chemical burns are common and serious ocular emergencies that require immediate and intensive evaluation and care. The victims of such incidents are usually young, and therefore loss of vision and disfigurement could dramatically affect their lives. The clinical course can be divided into immediate, acute, early, and late reparative phases. The degree of limbal, corneal, and conjunctival involvement at the time of injury is critically associated with prognosis. The treatment starts wit...

    Full Text Available Se realizó una revisión sobre el trauma ocular y su manejo en pacientes politraumatizados. Entre las causas más frecuentes de trauma ocular se encuentran los accidentes domésticos, laborales, juegos, actividades recreativas y deportivas. Involucran en un alto por ciento a niños y jóvenes, y predomina el sexo masculino en casi todos los trabajos revisados. No solo en Cuba sino en el mundo, el trauma ocular es fuente importante de ceguera unilateral o bilateral. Se presenta un breve compendio de los términos y definiciones actuales que son utilizados para el manejo del trauma ocular, su clasificación y la ventaja que ofrece aplicar el Puntaje del Trauma Ocular, OTS (Ocular Trauma Score, para el pronóstico de la agudeza visual final de acuerdo a los hallazgos clínicos encontrados en la evaluación inicial. Se hace referencia a los pacientes con politrauma y los aspectos a tener en cuenta por el oftalmólogo para tomar conducta cuando estos presentan heridas penetrantes o perforantes y tienen compromiso vital. En estos casos se hace necesaria la colaboración urgente de múltiples especialistas para primero mantener al paciente con vida y luego disminuir las complicaciones que repercuten en su pronóstico visual.A review was made on the ocular trauma and its management in multitrauma patients. The most common causes comprise domestic and occupational accidents, games, recreational and sport activities. It involves more frequently a high percentage of young people, with male prevalence in almost all the reviewed papers. Ocular trauma is an important source of unilateral or bilateral blindness not only in Cuba but worldwide as well. A brief summary of the current terms and definitions used to manage ocular trauma, their classification and the advantage of the Ocular Trauma Score (OTS to know the possible final visual acuity, according to the clinical findings at the emergency room, were presented.

    Full Text Available PURPOSE: To establish current definition, classification and staging, and to develop diagnosis and treatment recommendations for ocular allergy, by using Delphi approach. METHODS: Ten Latin American experts on ocular allergy participated in a 4-round Delphi panel approach. Four surveys were constructed and answered by panelists. A two-thirds majority was defined as consensus. Definition, classification, staging and diagnosis and treatment recommendations were the main outcomes. RESULTS: "Ocular allergy" was proposed as the general term to describe ocular allergic diseases. Consensus regarding classification was not reached. Signs and symptoms were considered extremely important for the diagnosis. It was consensus that a staging system should be proposed based on the disease severity. Environmental control, avoidance of allergens and the use of artificial tears were recommended as first line treatment. The secondary treatment should include topical anti-histamines, mast cell stabilizers and multi actions drugs. Topical non-steroidal anti-inflammatory and vasoconstrictors were not recommended. Topical corticosteroids were recommended as third line of treatment for the most severe keratoconjunctivitis. Consensus was not reached regarding the use of systemic corticosteroids or immunosuppressant. Surgical approach and unconventional treatments were not recommended as routine. CONCLUSION: The task of creating guidelines for ocular allergies showed to be very complex. Many controversial topics remain unsolved. A larger consensus including experts from different groups around the world may be needed to further improve the current recommendations for several aspects of ocular allergy.

    To evaluate the ocular effects of blunt trauma due to injury from a paintball pellet. Noncomparative case series. Thirteen patients who suffered ocular injury from paintballs are described. The patients presented to six different civilian and military emergency departments in tertiary care medical centers. Patients were treated for the ocular injury. Patients were evaluated for initial and final visual acuity. The reason for persistent loss of vision was delineated. There were 12 males and 1 female with an average age of 21 years (range, 12-33 years). Eleven of the 13 had no ocular protection at the time of the ocular injury. On initial examination, nine patients had a hyphema, nine had a vitreous hemorrhage, six had a retinal tear or detachment, three had corneal or corneal-scleral ruptures, and one had traumatic optic neuropathy. The final visual acuity was 20/40 or better in two patients, 20/50 to 20/150 in three patients, and 20/200 or worse in eight patients. Injuries due to paintball pellets can result in severe ocular damage and significant loss of vision. Eyecare professionals should be aware of the risks of this sport and must strongly advise participants to wear adequate protection when involved in this activity.

    2014-01-01

    Full Text Available Dual atrioventricular nodal nonreentrant tachycardia (DAVNNT occurs due to concurrent antegrade conduction over fast and slow atrioventricular nodal pathways and is treated by slow pathway modification. We describe a unique case of a patient with cardiac sarcoidosis who received inappropriate ICD shocks for DAVNNT. Atrial and ventricular device electrograms satisfied both rate and V>A criteria for ventricular tachycardia. We postulate that alterations in refractoriness and conduction as is seen in cardiac sarcoidosis (CS may have contributed to occurrence of DAVNNT.

    Examination of the ocular fundus is a critical aspect of the neurological examination. For example, in patients with headache the ocular fundus examination is needed to uncover “red flags” suggestive of secondary etiologies. However, ocular fundus examination is infrequently and poorly performed in clinical practice. Non-mydriatic ocular fundus photography provides an alternative to direct ophthalmoscopy that has been studied as part of the Fundus photography vs. Ophthalmoscopy Trial Outcomes in the Emergency Department (FOTO-ED) study. Herein, we review the results of the FOTO-ED study with a particular focus on the study's implications for the acute care of patients presenting with headache and focal neurologic deficits. In headache patients, we not only observed optic disc edema and optic disc pallor as would be expected, but also a large number of abnormalities associated with hypertension. Based upon subjects with focal neurological deficits, the FOTO-ED study suggests that the ocular fundus examination may assist with the triage of patients presenting with suspected transient ischemic attack. Continued advances in the ease and portability of non-mydriatic fundus photography will hopefully help to restore ocular fundus examination as a routinely performed component of all neurological examinations.

    2016-07-01

    A group of 32 Friesian and four Hereford calves, 3-4 months old with body weights between 100-120 kg, were purchased from a weaner sale. On arrival at the property the Hereford calves were treated with a combination anthelmintic containing 2 g/L abamectin and 80 g/L levamisole hydrochloride. Shortly afterwards they developed tremors and frothing from the mouth, and two died overnight. The Friesian calves were treated with the same anthelmintic on the following day, when some showed hypersalivation and frothing from the mouth. Examination of the three most severely affected Friesian calves revealed severe nicotinic-type symptoms including hypersalivation, frothing from the mouth, muscle tremors, recumbency, rapid respiration, hyperaesthesia, and central nervous system depression. Other calves showed mild to moderate signs of intoxication including restlessness, tail switching, salivation, tremors, frequent defaecation, mild colic and jaw chomping. Two calves died shortly afterwards. An adverse drug event investigation revealed that the formulation and quality of the anthelmintic was within the correct specification, and that the drench gun was functioning correctly. Suspected levamisole intoxication due to a combination of possible overdosing, dehydration, and stress caused by transportation and prolonged yarding. Susceptibility to levamisole toxicity in New Zealand calves can be increased if factors like dehydration or stress are present. Levamisole has a narrow margin of safety, and overdosing in calves can easily occur if the dose rate is not based on their actual weight or health status.

  11. Purinergic Receptors in Ocular Inflammation

    Directory of Open Access Journals (Sweden)

    Ana Guzman-Aranguez

    2014-01-01

    Full Text Available 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.

    Introduction. Sarcoidosis is a multisystemic granulomatous disorder characterized by multiple noncaseating granulomas involving intrathoracic lymph nodes and lung parenchyma. Recently, the use of anti-tumor necrosis factor alpha (anti-TNFα) agents has been introduced for therapy of chronic and refractory sarcoidosis with controversial results. Infliximab (Remicade) is a chimeric monoclonal antibody (mAb) that recognizes and binds TNFα, neutralizing its biological effects. In the present study,   99mTc labelled infliximab was used to study the expression of TNFα in sarcoid lesions and to evaluate its role as a predictive marker in response to therapy with Remicade. Material and Methods. A total of 10 patients with newly diagnosed sarcoidosis were enrolled together with 10 control patients affected by rheumatoid arthritis. All patients were studied by planar imaging of the chest with   99mTc-infliximab at 6 h and 24 h and total body [18F]-FDG PET/CT. Regions of interest were drawn over the lungs and the right arm and target-to-background ratios were analysed for   99mTc-infliximab. SUVmean and SUVmax were calculated over lungs for FDG. Results and Discussion. Image analysis showed low correlation between T/B ratios and BAL results in patients despite positivity at [18F]-FDG PET. Conclusion. In conclusion, patients with newly diagnosed pulmonary sarcoidosis, with FDG-PET and BAL positivity, showed a negative   99mTc-infliximab scintigraphy. PMID:25866780

    National surveys conducted in Japan between 1960 and 2004 suggest a gradually increasing incidence of sarcoidosis in women >50 years old with increased involvement of the eye, skin, and heart. However, whether this involvement is due to the increased age at diagnosis is still unclear. We aimed here to identify the age-related differences in organ involvement in sarcoidosis in Japan, as well as the historical changes in clinical characteristics and the age-specific distribution of cases at diagnosis. We reviewed 588 consecutive Japanese patients newly diagnosed with sarcoidosis between 1974 and 2012 at Jichi Medical University Hospital. We compared organ involvement between subgroups differentiated by sex and age (lymphatic extrathoracic organs such as the eye, heart, muscle, and kidney. The age at diagnosis has consistently increased over the past four decades. The monophasic distribution in men has tended to become biphasic, and the biphasic distribution in women monophasic. Increasing trends were apparent for hypercalcemia and involvement of the gastrointestinal tract, skin, nervous system, muscle, and kidney. Elderly patients at diagnosis had various extrathoracic involvement including eye, skin, and cardiac lesions. Moreover, the age at diagnosis of sarcoidosis has continued to increase in both sexes, influencing the recent trends in clinical characteristics. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available 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.

    Full Text Available We conducted a comparative survey of incidence and prevalence of pulmonary sarcoidosis in Southern (Crimean AR and Northern (Zhytomyr region regions of Ukraine by means of analysis of self-referred cases and cases, revealed at prophylactic radiological examination in 2011. The incidence of sarcoidosis in Crimea was 1.08 per 100 000 adult inhabitants; the prevalence was 4,59 per 100 000. In Zhytomyr region the incidence value (2,62 per 100 000 exceeded an equivalent value in Crimea by 2,4 times. The prevalence (7,86 per 100 000 was also higher than in Crimea by 1,7 times. Taking into account a significant impact of climate factor on sarcoidosis epidemiology, the incidence and prevalence of disease in Northern and Southern regions should be considered polar as for the regions of Ukraine. This makes it possoble to conclude that mean incidence of sarcoidosis in Ukraine ranges from 1,1 to 2,6 per 100 000 adult population, whereas the prevalence – from 4,6 to 7,9 per 100 000, which is equivalent to the level of Southern European countries.

    Gastric sarcoidosis with noncaseating granuloma is rare. Although corticosteroid produces a dramatic clinical response, it is unknown whether azathioprine show efficacy in prednisolone-dependent cases. Here, we report a case of gastric sarcoidosis in a 25-year-old man with severe epigastlargia. Gastroendoscopy revealed multiple map-like ulcerations. Histological examination showed multiple noncaseating granulomatous lesions in gastric mucosa, which were incompatible with diagnoses of Crohn's disease or tuberculosis. He was started on prednisolone at 30 mg/d, and his symptoms improved within 7-d. The prednisolone was gradually tapered by 5 mg every 2-wk, but oral azathioprine at 50 mg was added after symptoms recurred at tapered dose of 10 mg. Endoscopy 4-wk later showed healing ulcers, and, lymphocytic infiltration was absent. The efficacy of additional azathioprine in gastric sarcoidosis is not well defined. Here, we report a case of prednisolone-dependent gastric sarcoidosis that improved after additional azathioprine, and also review the literature concerning the treatment, especially for prednisolone-dependent cases.

    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.

    Aim: {sup 67}Ga citrate has been used long and successfully to diagnose and stage sarcoidosis. {sup 18}F-fluorodeoxyglucose ({sup 18}F-FDG) has been suggested as a positron emission tomography (PET) tracer for sarcoidosis imaging. This study aimed to analyze possible advantages of {sup 18}F-FDG-PET over {sup 67}Ga citrate scintigraphy during the primary assessment of patients with sarcoidosis. Patients and methods: twenty-four patients (11 men, 13 women, aged 52 years {+-} 12.4) with histologically proven sarcoidosis were investigated with {sup 18}F-FDG and {sup 67}Ga citrate. Equipment included a full-ring PET scanner (ECAT EXACT HR+, Siemens/CTI, Knoxville TN, USA) and a double-headed gamma camera (ECAM, Siemens, Illinois, USA) for scintigraphy. The mean time difference between the two studies was 6.5 days (range: 5-8 days). Results: there was a significant difference in the detection of pulmonary and nonpulmonary sarcoidosis lesions between planar {sup 67}Ga citrate scans and {sup 18}F-FDG-PET images (< 0.0021). A total of 64 lesions were detected with {sup 67}Ga citrate scans in the thorax and elsewhere with a mean of 2.6 lesions (4%) per patient, while 85 lesions were found with {sup 18}F-FDG-PET, with a mean of 3.5 lesions (4.1%) per patient. There was complete agreement between {sup 18}F-FDG and {sup 67}Ga citrate in thoracic manifestations in four (16.6%) patients, and in non-thoracic manifestations in five (20.8%) patients. The interobserver variability showed a kappa value of 0.79. Conclusion: {sup 67}Ga citrate and {sup 18}F-FDG are useful tracers for diagnostic evaluation of thoracic sarcoidosis. {sup 18}F-FDG seems to be more suitable for imaging the mediastinum, the bi-hilar lymph nodes, the posterior regions of the lungs and non-thoracic lesions. Further prospective studies are needed to clarify the role of both tracers in early diagnosis and staging of sarcoidosis, and to resolve questions concerning medical treatment and follow-up. (orig.)

    Ocular chemical burns are common and serious ocular emergencies that require immediate and intensive evaluation and care. The victims of such incidents are usually young, and therefore loss of vision and disfigurement could dramatically affect their lives. The clinical course can be divided into immediate, acute, early, and late reparative phases. The degree of limbal, corneal, and conjunctival involvement at the time of injury is critically associated with prognosis. The treatment starts with simple but vision saving steps and is continued with complicated surgical procedures later in the course of the disease. The goal of treatment is to restore the normal ocular surface anatomy and function. Limbal stem cell transplantation, amniotic membrane transplantation, and ultimately keratoprosthesis may be indicated depending on the patients' needs.

    Full Text Available An intact cerebellum is a prerequisite for optimal ocular motor performance. The cerebellum fine-tunes each of the subtypes of eye movements so they work together to bring and maintain images of objects of interest on the fovea. Here we review the major aspects of the contribution of the cerebellum to ocular motor control. The approach will be based on structural-functional correlation, combining the effects of lesions and the results from physiologic studies, with the emphasis on the cerebellar regions known to be most closely related to ocular motor function: 1 the flocculus/paraflocculus for high-frequency (brief vestibular responses, sustained pursuit eye movements and gaze-holding, 2 the nodulus/ventral uvula for low-frequency (sustained vestibular responses, and 3 the dorsal oculomotor vermis and its target in the posterior portion of the fastigial nucleus (the fastigial oculomotor region for saccades and pursuit initiation.

    Our study aimed to determine the clinical, therapeutic and prognostic features of ocular involvement in patients with Behçet's disease treated in our Department of ophthalmology. We conducted a retrospective data collection from medical records of 20 patients treated at the military hospital in Laayoune. All patients underwent complete ophthalmological examination and fluorescein angiography if necessary. OCT exam was performed in two patients. Ten patients had anterior uveitis, complicated in one case by ocular hypertonia; two patients had intermediate uveitis; eight patients had posterior segment involvement complicated in one case by intravitreal hemorrhage. Behcet's Disease (BD) is an systemic idiopathic inflammatory disease currently classified within primary non-necrotizing vasculitis. Ocular involvement is common and severe in Behçet's disease, with the potential to compromise the visual prognosis. Behcet's disease is common in Morocco. It can compromise patient's visual prognosis making the collaboration between ophthalmologists and internists particularly important.

    To evaluate ophthalmic ultrasound findings in the three presentation forms of ocular toxocariasis (peripheral or posterior pole granulomas and chronic endophthalmitis), in patients with confirmed diagnosis of ocular toxocariasis. 11 patients (11 eyes) with clinical and confirmed diagnosis of active ocular toxocariasis, presented positive ELISA test, were analyzed, prospectively, in the study. The patients were submitted to an ocular ultrasound examination (10-MHz transducer, contact technique). In the series of 11 patients, mean age was 7.9 years-old (range from 2 to 17 y), 73% male, referring previous contact with dogs (91%), and with the soil (50%), no referral of appetite perversion. In the analyses of compromised eyes (11 eyes), the ophthalmoscopic examination revealed the following distribution of the 3 forms of ocular toxocariasis: 7 cases (63.6%), posterior pole granuloma; 1 (9.1%), chronic endophthalmitis; 2 (18.2%), peripheral granuloma; and 1 (9.1%), posterior pole granuloma associated with chronic endophthalmitis. Visual acuity impairment: no light perception (3 eyes, 27.3%); hand motion (4 eyes, 36.4%); counting fingers at 10 cm (1 eye, 9.1%); 20/200 (1 eye, 9.1%); 20/70 (1 eye, 9.1%); undefined (1 eye, 9.1%). Serology was positive to Toxocara canis (ELISA test) in 100% of the cases. Ophthalmoscopy was difficult or impossible in 64% of the cases due to the media opacity. Ultrasound findings noted were vitreous membranes with retinal attachment (100%); parietal lesions (granulomas) with high (80%) or medium (20%) reflectivity. The most consistent ultrasound finding in the eye with toxocariasis was a high-reflectivity retinal mass, located in posterior pole or periphery, which may be calcified, and which has as main characteristic the adherence of vitreous membranes. In addition to clinical history, systemic evaluation and serology, the ultrasound can help in the diagnosis of ocular toxocariasis, especially in media opacities.

    Full Text Available Sarcoidosis is a multisystem disease that most commonly involves the lungs and the lymph nodes, but with genitourinary tract involvement, can easily mimic testicular cancer with metastasis to the lungs. We describe the case of a 30-year-old African-American male who presented with complaints of a headache, skin lesions, and a scrotal mass. A computed tomography scan of the head showed lesions in the frontotemporal and pons region, causing obstructive hydrocephalus. An ultrasound of the scrotum showed an enlarged epididymis bilaterally as well as a solid hypoechoic ill-defined mass on the right side, separate from the intact testis. Given the high suspicion for testicular malignancy with brain metastasis, a right orchiectomy was completed. The pathology revealed non-caseating necrotizing granulomas that stained negative for tubercular and fungal organisms, which was consistent with sarcoidosis. Additionally, the patient’s skin and central nervous system (CNS lesions improved on steroids that had been started for cerebral edema. Given the predilection of testicular cancer for CNS metastasis, neurosarcoidosis can also be mistaken for testicular cancer metastasis to the CNS, as seen in our case. Differentiating testicular cancer from genitourinary sarcoidosis is difficult but can be clarified using a combination of clinical presentation, epidemiology, serum markers (ACE, AFP, B-HCG, biopsies from skin/lymph nodes, and sometimes imaging. It is critical to differentiate genitourinary sarcoidosis from malignancy, as a misdiagnosis can lead to unnecessary surgical interventions, which have important implications for future fertility. There can also be a coexistence of as well as an association between testicular cancer and sarcoidosis, which should be recognized by health care providers. Both authors contributed equally to the manuscript.

    Tumor necrosis factor-alpha (TNF-α) inhibitors are regarded as the third-line therapy in sarcoidosis, the first choice generally being infliximab. To date, data regarding response to adalimumab in sarcoidosis patients intolerant to infliximab are lacking. The objective of this retrospective observational study was to establish if adalimumab could achieve stabilization or improvement of the disease in refractory sarcoidosis patients who developed intolerance to infliximab. Sarcoidosis patients referred to St Antonius Interstitial Lung Diseases Center of Excellence, Nieuwegein, The Netherlands, between January 2008 and April 2015 who switched from infliximab to adalimumab were included. Changes in organ function, inflammatory biomarker levels, and adverse events were retrieved from medical records. Out of 142 infliximab treated patients, 18 (13%) had to discontinue treatment due to antibody formation or severe adverse events and switched to adalimumab therapy. Organ function improved in 7 patients (39%), was stable in 6 patients (33%), and worsened in 5 patients (28%) after 12 months of treatment or after 6 months if evaluation after 12 months was not available (n = 4). In none of the patients biomarker levels of soluble interleukin-2 receptor (sIL-2R) deteriorated. Median decrease in sIL-2R was 3614 pg/mL. Most reported adverse event was infection (n = 10). Adalimumab is an effective alternative for patients intolerant to infliximab. The switch to adalimumab achieved clinical improvement in 39% and stabilization in 33% of patients intolerant to infliximab. Further research is needed to develop guidelines on how to use adalimumab for sarcoidosis in terms of dosing regimen. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available This paper presents a case of ocular changes in leishmaniasis in a dog brought in for examination because of visible changes in the eyes. An ocular manifestation in leishmaniasis can be bilateral or unilateral. Changes most often occur on the conjunctive and the front segment of the eye, the cornea and iris. From 70 to 80% of dogs diseased with leishmaniasis exhibit frontal uveitis, and dry eye, keratoconjunctivitis sicca, is also a frequent finding. Based on the clinical picture and the positive immunochromatographic rapid test it was established that the dog was diseased with leishmaniasis.

    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.

Solo cerca del 10 % de las personas que tienen una o más lesiones metastásicas intraoculares son detectadas clínicamente antes de la muerte. A menudo, el carcinoma metastásico ocular es diagnosticado por el oftalmólogo ante la presencia de síntomas oculares. Las lesiones están localizadas con preferencia en coroides. Nos motivo a realizar la presentación de este caso la presencia de lesiones intraoculares múltiples tumorales metastásicos en un paciente cuyo síntoma de presentación fue la disminución de la agudeza visualThe eye metastatic carcinoma is considered the most frequently found intraocular malignant neoplasia. Only 10 % of the persons with one or more metastatic intraocular injuries are clinically detected before death. The metastatic ocular carcinoma is often diagnosed by the ophthalmologist in the presence of ocular symptoms. The injuries are preferably located in the choroid. The appearance of multiple metastatic intraaocular tumoral injuries in a patient whose chief complaint was the reduction of visual acuity motivated us to presente this case
