Membranous nephropathy (MN) accounts for about 20 percent of cases of the nephrotic syndrome. The importance of renal biopsy in establishing the diagnosis is emphasized. In the great majority of MN patients, no etiologic factor can be discerned. In a significant minority, MN appears to be a manifestation of sarcoidosis, diabetes, lupus, syphilis, malaria, or toxicity from heavy metals or drugs. In some cases the "cause" is neoplasia (including lymphoma) or a viral infection. Massive proteinuria, hypoproteinemia and edema are the principal manifestations of MN, finally resulting in renal failure. Treatment consists chiefly of diet and diuretic drugs. In the more pronounced cases, corticosteroids may have a favorable effect and in very resistant cases, cyclophosphamide is indicated. Judicious use of these modalities if often associated with the diminution or disappearance of the clinical signs of MN.

Six patients with severe and complicated falciparum malaria (6.7 +/- 2.7 WHO criteria) were admitted to our Intensive Care Unit. All patients acquired the disease while travelling in tropical Africa without appropriate chemoprophylaxis. The clinical manifestations included hyperpyrexia (all patients), chills (4), sweating (2), asthenia (3), anorexia (2), headache (1), arthralgias (1), vomiting (4), diarrhoea or abdominal discomfort (3), jaundice (2) and disturbances of consciousness (4). All patients had anemia, thrombocytopenia, hyponatremia, hypoproteinemia, hypoalbuminemia, hypocalcemia and acute renal failure, in one case associated with anuria. A low grade parasitemia was observed in two patients and a high grade parasitemia (20%-58% of erythrocytes) in four. Exchange transfusion was performed only in high parasitemic patients and all of them survived. All patients were treated with quinine, a sulfonamide and pyrimethamine. Additionally, five patients received oxytetracycline, doxycycline or clindamycin. Three patients required hemodyalisis. Five patients had delirium, coma or seizures. All patients had at least one sign of hepatic impairment: liver enlargement, jaundice or increased bilirubin or aminotransferase levels. Two patients had spleen enlargement. Laboratory findings suggested disseminated intravascular coagulation in four patients. Four patients developed pulmonary changes and three of them required mechanical ventilation. A Swan-Ganz catheter was placed in four patients. In three of them (two with pulmonary edema) the pulmonary capillary wedge pressure was initially increased, which suggested a cardiogenic or hypervolemia mechanism, but soon returned to normal level. One patient with low grade parasitemia died because of adult respiratory distress syndrome after 18 days. In our series, the degree of parasitemia was not related to the severity of the disease.
