title: [Kidney failure as a consequence of sarcoidosis].
abstract: A 27-year-old man was admitted to hospital because of weight loss, fatigue and lack of appetite over the previous few weeks and cervical lymphadenopathy. Chest X-ray demonstrated several patchy infiltrates in both lungs. There was also evidence of progressive renal failure (creatinine concentration: 3,0 mg/dl) and hypercalcaemia (2,8 mmol/l). Bronchoalveolar lavage and renal biopsy confirmed sarcoidosis. Fundoscopy revealed eye involvement (several circumscribed, partly confluent, whitish nodules). Wegener's granulomatosis was excluded because no anticytoplasmic antibodies were demonstrated. Administration of steroids (at first daily 60 mg methylprednisolone) quickly resulted in a normal blood calcium level and normal renal function. These findings suggest that the early stage of sarcoidosis consists of in principle reversible functional changes. The differential diagnosis from systemic diseases is often difficult. If sarcoidosis is suspected one must search for rare organ manifestations so that therapy can be started as soon as possible.
