          Abstract

          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.

          Sarcoidosis.

          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.

              Prognostic determinants of long-term survival in Japanese patients with cardiac sarcoidosis treated with prednisone.

              Cardiac involvement is an important prognostic factor in sarcoidosis, but reliable indicators of mortality risk in cardiac sarcoidosis are unstudied in a large number of patients. To determine the significant predictors of mortality and to assess the efficacy of corticosteroids, we analyzed clinical findings, treatment, and prognosis in 95 Japanese patients with cardiac sarcoidosis. Twenty of these 95 patients had cardiac sarcoidosis proven by autopsy; none of these patients had received corticosteroids. We assessed 12 clinical variables as possible predictors of mortality by Cox proportional hazards model in 75 steroid-treated patients. During the mean follow-up of 68 months, 29 patients (73%) died of congestive heart failure and 11 (27%) experienced sudden death. Kaplan-Meier survival curves showed 5-year survival rates of 75% in the steroid-treated patients and of 89% in patients with a left ventricular ejection fraction > or = 50%, whereas there was only 10% 5-year survival rate in autopsy subjects. There was no significant difference in survival curves of patients treated with a high initial dose (> 30 mg) and a low initial dose (> or = 30 mg) of prednisone. Multivariate analysis identified New York Heart Association functional class (hazard ratio 7.72 per class I increase, p = 0.0008), left ventricular end-diastolic diameter (hazard ratio 2.60/10 mm increase, p = 0.02), and sustained ventricular tachycardia (hazard ratio 7.20, p = 0.03) as independent predictors of mortality. In conclusion, the severity of heart failure was one of the most significant independent predictors of mortality for cardiac sarcoidosis. Starting corticosteroids before the occurrence of systolic dysfunction resulted in an excellent clinical outcome. A high initial dose of prednisone may not be essential for treatment of cardiac sarcoidosis.
