Clinical Features and Prognostic Significance of Limited and Diffuse Endobronchial Sarcoidosis.

Aims: Airway involvement is a common feature of sarcoidosis and mucosal abnormalities may be evident in the respiratory tract. However, firm data establishing the clinical features and prognosis of sarcoidosis in these patients is lacking although the incidence of endobronchial disease is high. The purpose of this study was to evaluate the clinical features of the patients with limited, diffuse and no endobronchial involvement. Another aim was to investigate the prognostic differences between these patients. Methods: We conducted a retrospective study to evaluate the clinical and laboratory findings of 48 patients with endobronchial sarcoidosis and 50 patients without endobronchial involvement seen at our institution. The patients fulfilled the clinical, radiologic or both features of sarcoidosis supported by the histopathologic evidence of noncaseiting granulomas. Six to ten bronchial biopsies were taken from each patient. The sample was considered positive if it demonstrated noncaseiting granulomas with negative fungal and mycobacterial cultures. The patients were classified into three groups according to the histopathologic biopsy results: 1) No endobronchial involvement, 2) Limited endobronchial involvement: One biopsy site positive and 3) Diffuse endobronchial involvement: Two or more biopsy sites positive for noncaseaiting granulomas. Results: Bronchial biopsy was positive in 82% of the abnormal appearing airways while it was diagnostic in 36% of the normal appearing mucosa. The most frequent bronchoscopic appearence was miliary infiltration. Nodular, erythematous lesions and edematous mucosal swelling were other bronchoscopic findings. There were no significant differences between the three groups for FEV1, FVC, TLC, DLCO/VA serum and 24 h urinary calcium levels. Serum ACE levels were significantly higher (p<0.001) in patients with limited and diffuse bronchial involvement compared to patients with no endobronchial disease. The extrapulmonary organ involvement (p<0.001) and progressive disease incidence was more frequent (p<0.001) in patients with limited and diffuse endobronchial disease. Conclusions: Endobronchial involvement in sarcoidosis appears to be a significant predictive risk factor for progressive disease. Patients with limited or diffuse endobronchial disease have more severe extrapulmonary organ involvement and a worse prognosis than patients without endobronchial disease. Bronchoscopy may identify such patients carrying a risk factor for progressive sarcoidosis.

A Case of Sarcoidosis Presenting as Cirrhosis and Portal Hypertension.

Sarcoidosis is a systemic granulomatous disease of unknown etiology that can involve nearly all organs. Liver is the third most commonly affected organ following the lungs and the lymph nodes. Cases with liver sarcoidosis are usually silent clinically while a few can progress to cirrhosis and portal hypertension in less than 1% of the patients. A 56 year old female was referred for ecchymosis, protuberant abdomen, bilateral pretibial and ankle edema. Medical history did not reveal any previous disease. Ascites, hepatomegaly, splenomegaly, and facial telengiectasies were present on physical examination. Chest x-ray and CT were normal. Papules and plaques on the knees developed six days after admission. Skin biopsy revealed granulomatous dermatitis. Serum ACE was 250 IU/L. Liver biopsy showed non-caseiting granulomas, severe hepatitis and fibrosis. Sarcoidosis was confirmed based on high serum ACE, histopathologic findings of the skin and liver biopsy samples that revealed non-caseiting granulomas. We report a case of sarcoidosis complicated by cirrhosis as the initial manifestation of the disease without lung involvement. An extensive literature review of sarcoidosis, focusing on case reports, which presented with cirrhosis and portal hypertension without lung involvement, was made.

The Value of Cytology in the Diagnosis of Pleural Effusions.

The aim of this study is to assess the value of cytology in the diagnosis of pleural effusions. It is a retrospective review of the patients with pleural effusions admitted at our clinic in a 8-year period. We evaluated the cytological and diagnostic results of 470 patients. Male to female ratio was 3:1 with a mean age of 38.6 years (range 18-76 years). Samples were processed and evaluated according to the standard methods. Cytology results were reviewed and the patients were stratified according to the their final diagnosis of the 470 effusions, 40 were transudates. Among 430 exudates, 190 (74.8%) were malignant on pleural fluid analysis alone. Adenocarcinoma was the most common malignancy. Tuberculosis was the second most frequent etiology for the exudative effusions. Cells in benign or malignant effusions were easily recognized without further invasive evaluation, contributing to diagnosis and therapeutic decisions. Diagnostic power of cytology was high and showed a good correlation with the eventual pathologic diagnosis, with an overall 70.6% sensitivity. Cytologic examination of the pleural fluid is a simple minimally invasive procedure as an initial step in the diagnostic work-up of patients with pleural effusions. It does not only provide high diagnostic sensitivity but also leads the clinician in the correct algorithm as the most informative and leading test even when not diagnostic on its own.

Role of Anxiety on Patient Intolerance during Bronchoscopy.

Aims: There are no current data about the adverse effects of anxiety on patient intolerance during bronchoscopy.The aim of our study was to assess the correlation between anxiety and patient intolerance during bronchoscopy. Study Design: Retrospective research study Place and Duration of Study: Department of Pulmonary Diseases, Cerrahpasa Medical Faculty, between January 2010 and 2013 March. Methodology: Data from 94 patients were analyzed. The mean age of the patients was 59 years. Bronchoscopy was performed for lung cancer in 54, pulmonary nodules in 26 and pulmonary infiltration in 14 patients. Hospital Anxiety Depression scale was used to appraise the anxiety symptoms. Cytologic examination of bronchoalveolar lavage, and sputum samples were performed in each patient when available. Results: The anxiety or fear profile of the patients before bronchoscopy were as follows: dyspnea (78%), malignant disease (74%), nasal, laryngeal or tracheal irritation (70%), bronchoscopic findings (68%), and hemorrhage (42%). Bronchoscopic examination was intolerable in 14 cases while there was great difficulty to perform the procedure in 18 patients. Cytologic analysis revealed severe in 18, moderate in 22, and mild dysplasia in 25 patients while it was normal in 29 subjects. Hospital Anxiety Depression scale was over eight in 33 patients. The scale was over eight in 13 out of 14 patients who were intolerant to bronchoscopy. Cytology revealed severe in one and moderate dysplasia in another patient intolerant to bronchoscopy. Conclusions: Anxiety appears to be the predominant factor for patient intolerance during bronchoscopy. Pulmonary function, atypical or dysplastic cytomorphological changes in sputum or bronchoalveolar lavage cytology did not show correlation with patient performance.
