Evaluation of quality of life in sarcoidosis patients.

Health-related quality of life (QOL) has become an important topic in health care. However, hardly any attention has been paid to QOL in sarcoidosis. Therefore, the aim of this study was to assess the impact of sarcoidosis on QOL. Sixty-four sarcoidosis patients completed the World Health Organization Quality of Life assessment instrument (WHOQOL-100) and the Beck Depression Inventory (BDI). For the WHOQOL-100 a matched group of healthy controls was selected. Patients were divided into two groups: group I (n = 37) consisted of patients with actual symptoms, group II (n = 27) consisted of asymptomatic patients. The WHOQOL-100 revealed a number of areas in which sarcoidosis patients, especially those with current symptoms, experienced problems. A major symptom in both groups of sarcoidosis patients was fatigue. No association between the facet fatigue and the domain psychological health was found. Depressive symptoms (BDI) were associated with psychological function (WHOQOL-100). No association between pulmonary function tests and QOL was found. In conclusion, this study shows that sarcoidosis has a considerable impact on the QOL of patients. The WHOQOL-100 appeared to be a sensitive instrument to measure fatigue--one of the most common symptoms in sarcoidosis--which otherwise is difficult to assess objectively.

Diagnosis of Pneumocystis carinii Pneumonia in HIV-Positive Patients

OBJECTIVEnTo evaluate the contribution of bronchoalveolar lavage (BAL) and bronchial brushing (BB) and the use of different tinctorial stains in the detection of Pneumocystis carinii (PC) in human immunodeficiency virus (HIV)-positive patients.nnnSTUDY DESIGNnIn a retrospective study, 195 HIV-positive patients suspected of a pulmonary infection underwent bronchoscopy with BAL. In 143 cases subsequent BB was performed. On 135 BAL fluid cytocentrifuge preparations four staining techniques were applied simultaneously: May-Grünwald-Giemsa (MGG), toluidine blue-O (TOL), Papani-colaou (PAP) and Grocott methenamine silver (GRO).nnnRESULTSnPC was recovered in 79 (40.5%) cases. The yields of MGG and TOL were identical (33.3%). PAP and GRO showed lower results, 31.1% and 29.6%, respectively. These differences were not statistically significant. The combination of BAL and BB revealed 64 cases of PC infection. BAL was positive in the vast majority of cases (63, 44.1%). BB was positive in 54 (37.8%). The combination of positive BB with negative BAL was present in one case. However, 10 cases of PC were found with the use of BAL and not detected by BB (P < .01).nnnCONCLUSIONnThe results of this study indicate that to confirm a PC infection in HIV-positive patients, the use of bronchoalveolar lavage with a single staining technique is appropriate. Bronchial brushing seems to be of limited additional value.
