It is likely that sufficient doses of mannitol may lead to ARF. Limitation of dose may prevent and treatment with hemodialysis may reverse ARF in these instances.

Two male patients with thrombotic thrombocytopenic purpura (TTP) were found to have antibodies to the human immunodeficiency virus (HIV). In one patient, platelet-associated antibody levels were measured serially and were found to be initially elevated, but the levels decreased with initiation of successful therapy. The simultaneous occurrence of these two conditions in two of three patients admitted for TTP within the previous 2 years at this institution suggests an association between the two diseases. The precise nature of this association remains speculative inasmuch as the pathogenesis of TTP remains uncertain.

In senior salt-sensitive patients with hypertension, coadministration of misoprostol with diclofenac attenuated the blood pressure elevation and renal vasoconstrictive effects of diclofenac and was well tolerated.

A patient with renal failure due to myeloma kidney and coincident digitalis intoxication due to prescribed daily digoxin administration was treated with digoxin-specific antibody fragments and plasmapheresis. Rapid response to therapy was noted, removal of digoxin-antidigoxin antibody complexes was confirmed, and prevention of delayed rebound toxicity was documented. We suggest that this is the therapy of choice in similar individuals.
