The nonerythropoietic component of early labeled bilirubin in plasma and bile was studied in 7 patients with acute infectious hepatitis during the late convalescent stage, in 13 patients with Laennec-type liver cirrhosis, and in 7 control subjects after intravenous injection of a tracer dose (2.5 muCi) of 4-14C-delta-aminolevulinic acid (14C-deltaALA). All subjects were examined during the nonicteric stage. In control subjects, the mean cumulative radioactivity readings in 4 hours were 29.6 +/- 4.7 X 10(3) d.p.m. per milligram times 4 hours in plasma and 27.0 +/- 1.2 X 10(3) d.p.m. per milligram times 4 hours in bile. In acute infectious hepatitis patients, the mean cumulative radioactivity readings for both plasma and bile in 4 hours were approximately twice that found in control subjects. In mild cirrhotic patients with enlarged liver on scintigram, the mean cumulative radioactivity readings for both plasma and bile were approximately 1.4 times that in control subjects. In patients with more advanced cirrhosis and markedly small livers on scintigram, the mean cumulative radioactivity readings for both plasma and bile were as low as approximately 0.5 that of control subjects. These findings seem to indicate the important role of the liver in the production of the nonerythropoietic component of early bilirubin in man.

50 children under the age of 15 years were studied who had been hospitalized in two hospitals in the Dominican Republic with HIV diagnosed by the presence of biphasic hyperbilirubinemia and elevation of glutamic-pyruvic and glutamic-oxalacetic transaminases. The sera of the patients were examined for the presence of leptospirotic immunoglobulin M (IgM) antibodies by means of the enzymatic immunoassay method (UREASA-ELISA). The Leptospira-positive sera were also investigated for the presence of hepatitis B surface antigen (HBsAg) and for the IgM antibody (ab) of the hepatitis A virus (ab-HAV) by ELISA. 5 cases were positive for IgM Leptospira antibodies (10%), not finding in this percentage the presence of HBsAg; 3 of the 5 Leptospira-positive samples demonstrated the presence of ab-HVA-IgM. Only 2 cases (4%) presented IgM Leptospira antibodies. Out of the 5 cases with IgM antibodies, males predominated (3/5). When compared to negative cases, however, there were more rural elements among them than in negative cases: regarding origins (10% vs. 16%), agricultural workers (40% vs. 20%), contact with cattle and fresh water (80% vs. 40%), and daily contact with humid soil in living quarters (60% vs. 48%). The clinical picture of the 5 positive cases featured myalgia (p = 0.05) and abdominal pain (p = 0.05). The stiffness of neck was relatively more frequent in positive cases (20%) than in negative cases (7%); also, fever (100% vs. 80%), vomiting (60% vs. 22%), headache (80% vs. 56%), constipation (20% vs. 9%), and hepatomegaly (100% vs. 71%). There was clear evidence that leptospirotic infection must be watched and also its association with acute infectious hepatitis.
