Protein-losing enteropathy in systemic lupus erythematosus.

A 33-year-old woman presented a recurrent steroid-sensitive protein-losing enteropathy as the major manifestation of systemic lupus erythematosus. An increased capillary permeability for proteins is considered to be the most likely explanation.

Sclerosing peritonitis with mural bowel fibrosis in a patient on long-term CAPD.

A 66 year old white woman developed an incomplete small-bowel obstruction after 3 years of CAPD with lactate containing solutions. There were six episodes of peritonitis. The bowel obstruction was not due to a "sclerosing obstructive" (encapsulating) peritonitis but to a diffuse sclerosis of the serosal membranes extending into the muscle layers of the small and large bowels ("mural fibrosis").

Transient acute renal failure due to tumor-lysis-induced severe phosphate load in a patient with Burkitt's lymphoma.

A patient who developed acute renal failure during a period of acute tumor lysis is reported. Evidence is presented that hyperphosphatemia and/or hyperphosphaturia caused the acute renal failure. The literature on the subject is reviewed and pathogenetic mechanisms are discussed.
