Polyclonal gammopathy with beta-globulin-gamma-globulin bridging. Two unusual cases.

Polyclonal gammopathy with beta-globulin-gamma-globulin (beta-gamma) bridging has been classically, though not exclusively, described with cirrhosis. We studied two unusual cases that exhibited polyclonal gammopathy with beta-gamma bridging. In the first case, the coexistence of Kaposi's sarcoma appeared with angioimmunoblastic lymphadenopathy. In the second, liver disease developed as a complication of alpha 1-antitrypsin deficiency and retroperitoneal malignant fibrous histiocytoma involving the porta hepatis.

Serum high-density lipoprotein cholesterol concentrations in hypo- and hyperthyroidism.

We studied alterations in the concentration of high-density lipoprotein cholesterol and of other lipid categories (total cholesterol, low-density lipoprotein cholesterol, very-low-density lipoprotein cholesterol, and triglycerides) in serum in hypo- and hyperthyroid states, and compared these findings with those of a control group. In the latter group the lipids showed an age-related increase in concentration but with a decrease in the eighth decade in all categories. In untreated hypo- and hyperthyroid subjects, all of the lipid values differed significantly from those of the controls but promptly returned to normal values upon treatment. In hypothyroid patients who are prone to develop coronary heart disease, the concentrations of high-density lipoprotein cholesterol were high, suggesting protection against heart disease, while the ratio to total cholesterol indicated the contrary. The exact opposite of these relationships was seen in hyperthyroid disorders. This apparent paradox suggests that the low-density lipoprotein cholesterol in serum, with its established atherogenic effect, should be given at least equal, if not more, weight than the concentration of high-density lipoprotein cholesterol in serum, with its alleged protective effect.

Pre-renal azotemia mimicking chronic renal failure in a hypotensive patient.

A 56-year-old Samoan man with a documented history of hypertension, who presented with atrial fibrillation and hypotension, quickly developed renal failure with a serum urea nitrogen of 1.370 g/L and a serum creatinine of 92 mg/L. After hydration of the patient, the creatinine value became normal in two days, the urea nitrogen in four days. The urinary creatinine output during the first 24 h of hospitalization was 3.7 g. This case illustrates the rapidity with which unusually large amounts of creatinine (more commonly seen in chronic renal failure) can accumulate and be excreted in pre-renal failure. It also reaffirms the usefulness of the urea nitrogen/creatnine ratio in evaluating the causes of azotemia.
