SARCOIDOSIS 2015

Sarcoidosis is a systemic, inflammatory, granulomatous disease of unknown origin that can involve any organ. More than 90% of patients have thoracic sarcoidosis, which most frequently presents with bilateral hilar lymphadenopathy. In approximately 20% of patients with thoracic sarcoidosis there is involvement of the lung parenchyma as well as mostly asymptomatic cardiac sarcoidosis in up to 55% of patients. Most patients are asymptomatic and the diagnosis is an incidental finding on chest X-ray or during clarification of unspecific symptoms, such as fatigue or cough...

Sarcoidosis is a multisystem granulomatous disorder. Neurological manifestations as a presenting symptom are relatively rare. A 26-year-old male presented with a five-week history of headache suggestive of raised intracranial pressure. He subsequently developed transient episodes of mild right-sided hemiparesis and numbness. Magnetic resonance imaging (MRI) of brain revealed widespread inflammatory white matter lesions, an ischaemic focus in the left corona radiata, and widespread microhaemorrhages consistent with a more diffuse vasculopathy...

Sarcoidosis is a multisystem granulomatous disease of unknown etiology that most commonly affects the lungs. Treatment of sarcoidosis can be challenging as it is often difficult to measure disease activity and distinguish active inflammation from fibrosis. Identifying the inflammatory mediators in sarcoidosis has led to the development and use of novel therapeutic agents. The goal of pharmacotherapy is to decrease granuloma accumulation, ameliorate symptoms and improve organ function. Systemic corticosteroids remain the first line treatment...

INTRODUCTION: Very few cases of scar sarcoidosis affecting the eyes and bone together have been reported in the last few years. CASE PRESENTATION: We report a case of a 49-year-old Spanish man with recurrent bilateral granulomatous uveitis and a fistulous nodular lesion in the left pre-tibial region (scar granuloma) on the site of an 8-year-old scar. He presented with bilateral hilar adenopathies and elevation of inflammatory markers and angiotensin-converting enzyme...

BACKGROUND: Although thyroid eye disease is a common complication of Graves' disease, the pathogenesis of the orbital disease is poorly understood. Most authorities implicate the immune response as an important causal factor. We sought to clarify pathogenesis by using gene expression microarray. METHODS: An international consortium of ocular pathologists and orbital surgeons contributed formalin fixed orbital biopsies. RNA was extracted from orbital tissue from 20 healthy controls, 25 patients with thyroid eye disease (TED), 25 patients with nonspecific orbital inflammation (NSOI), 7 patients with sarcoidosis and 6 patients with granulomatosis with polyangiitis (GPA)...

We report herein a case of laryngeal sarcoidosis that was refractory to systemic corticosteroids, but that improved spontaneously. A 49-year-old woman complained of dysphagia and hoarseness with accompanying edematous swellings of both arytenoid regions. She was referred to our hospital after systemic corticosteroid therapy failed to achieve any improvement. Laryngoscopy showed marked edema of the epiglottis and both arytenoid regions. The flow-volume curve on spirometry showed flattening of the expiratory flows...

PURPOSE OF REVIEW: Sarcoidosis is a multisystem inflammatory disease, characterized by the presence of noncaseating granulomas. Ocular inflammation is often the first manifestation of the disease, and uveitis can be the driving force for treatment. The goal of this review was to provide an update on the relationship between ocular and systemic disease, with a particular focus on cardiac sarcoidosis. RECENT FINDINGS: Chest radiograph remains the best imaging tool for sarcoidosis, although newer modalities, such as whole-body PET scan, cardiac MRI, and chest computed tomography (CT), may provide additional valuable information in select populations...

AIM: The aim of this study was to investigate the clinical and pathological features of hepatic sarcoidosis in symptomatic cases. METHODS: Twenty-two symptomatic hepatic sarcoidosis cases were included in the study. Hepatic sarcoidosis was determined by typical imaging, histopathology, and high angiotensin-converting enzyme levels. Demographic data, laboratory data, imaging findings, liver biopsies, and clinical findings were analyzed. Portal hypertension (PH) was defined by the presence of ascites and/or varices; imaging findings suggestive of PH-splenomegaly (> 12 cm on longest axis); portal vein dilation (> 13 mm); collateral vessel formation; and hepatic venous pressure gradient ≥ 6 mmHg...

OBJECTIVES: Systemic diseases form a rare heterogeneous group of diseases, with important morbidity caused by disease evolution and/or treatment. We describe the clinical features and outcome of patients with these diseases admitted to a referral hospital intensive care unit (ICU). METHOD: We conducted a retrospective case review of all patients with systemic diseases (n = 86) admitted to the medical ICU of Leuven University Hospital between May 2007 and September 2012...

Sarcoidosis is a systemic disorder of unknown etiology, which may involve various tissues and organs and is characterized by a noncaseating granuloma reaction. While pathogenesis is not yet clear, cellular immune system activation and nonspecific inflammatory response occur secondarily to several genetic and environmental factors. T helper 1-cells and macrophage-derived pro-inflammatory cytokines stimulate the inflammatory cascade and formation of granuloma occurs as a result of tissue permeability, cell influx, and local cell proliferation...

AIM: Sarcoidosis is a chronic multisystem disease that usually has a good prognosis but in some cases, especially when cardiac involvement occurs, the outcome is fatal. Cardiac sarcoidosis is insidious to diagnose because it is usually asymptomatic and when clinically apparent, it may have a wide variety of manifestations. The aim of this study was to investigate the possible cardiac involvement in cutaneous sarcoidosis patients. METHODS: Diagnosis of cutaneous sarcoidosis was confirmed by skin biopsy, laboratory tests and radiological findings in 13 Caucasian Patients...

Sarcoidosis is a granulomatous disorder that frequently affects the lungs. Cough is commonly reported by patients and can significantly reduce health-related quality of life. The mechanism of cough is unknown but airway inflammation, mechanical distortion from pulmonary fibrosis and disruption of the vagus nerve are possible. Recent evidence suggests cough reflex hypersensitivity may also be an important mechanism and predictor of the frequency of cough. The investigation of cough should evaluate common causes such as asthma, gastro-oesophageal reflux and rhinitis...

Although the most feared cardiac manifestation in cardiac sarcoidosis is the onset of ventricular arrhythmia, some patients may present with supraventricular arrhythmias. We present a rare case of cardiac sarcoidosis associated with double tachycardia manifesting as atrial flutter and ventricular tachycardia.

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...

Sarcoidosis is a systemic granulomatous disease of unclear etiology with characteristic pulmonary lesions. We describe 2 unique cases of sarcoidosis where after approximately 20 years of clinical quiescence, patients developed interstitial opacities on chest CT scan and an increase in shortness of breath. With lack of therapeutic response to a course of prednisone, both patients underwent a surgical lung biopsy that revealed a pattern consistent with Usual Interstitial Pneumonia (UIP) with honeycombing and fibroblastic foci...

We present a case of a 50-year-old woman with multiple occupations in the liver. Liver cancer was strongly suspected initially according to the results of imaging examination. However, sarcoidosis was confirmed subsequently by liver biopsy, so methylprednisolone was then prescribed and the patient showed favorable therapeutic response. This case report suggests that hepatic mass in Chinese patients without any history of hepatitis virus infection should be carefully investigated before giving a diagnosis of liver cancer...

There are many differential diagnoses in investigating patients who present with retinal vasculitis, and the laboratory investigations used to investigate this have low-to-moderate sensitivity and/or specificity. Diagnoses include conditions such as tuberculosis or sarcoidosis, which may require long courses of antibiotics or immunosuppression. Influenza vaccination has been recognised as a cause of vasculitis for decades, although a purely ocular presentation is rare. We present a case of a 78-year-old Caucasian woman presenting with a single vessel arterial vasculitis of the right eye 8 weeks following influenza vaccination at her local general practitioner practice...

Sarcoidosis is an idiopathic inflammatory disorder characterized by noncaseating granulomas, which can affect any organ system. The lungs are most commonly affected but extrapulmonary sites may cause the initial and/or sole symptoms. In this review, the disease manifestations and treatment are described, with particular emphasis on the management of each affected organ system. Diagnosis and management can be difficult and greatly affect quality of life, but despite these challenges, it is possible to successfully manage patients with sarcoidosis in the primary care setting...

PURPOSE: The distinction between tuberculosis (TB), a worldwide infectious granulomatosis requiring specific antibiotic therapy, and sarcoidosis, a rare granulomatous disease that may require corticosteroids is not straightforward and may result in diagnostic and therapeutic delay. METHODS: We prospectively and consecutively evaluated the presence of epithelioid granulomas in minor salivary gland biopsy of 65 consecutive patients with TB. RESULTS: In our study, 10...
