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.

The authors report a case of sarcoidosis associated with protein losing enteropathy. The diagnosis of intrathoracic stage I sarcoidosis was based on x-ray and biopsy of mediastinal lymph nodes. Enteric protein loss was suspected because of edema lasting for 2 yr, hypoproteinemia, decreased concentrations of serum immunoglobulins, and lymphopenia involving mainly T-cells and proved by 51CrCl3 test (21%/120 hr). Lymphography was consistent with granulomatous involvement of retroperitoneal lymph glands while small bowel biopsy showed blunt villi and dilated lacteals. All the pathological parameters normalized after 6 mo of prednisone treatment. In some cases of sarcoidosis, when abdominal lymph glands are involved, cellular and humoral immunologic derangements may be caused or potentiated by excessive enteric protein and lymphocyte loss.
