Liver disease in blood donors with raised transaminases.

1000 consecutive blood donors had their liver functions studied. 110 donors (11%) were found to have raised ALT of more than twice normal levels. 29 donors had liver biopsies done. Histologically 23 had fatty change, 5 had chronic persistent hepatitis and 1 had liver cirrhosis. Fourteen out of the 23 donors with fatty change also had hypercholesterolemia and hypertriglyceridemia. Viral serology of the 110 donors showed that 3 donors were HBsAg positive, 5 donors were Anti-HAV (IgM) positive and 20 donors were Anti-HBc (IgM) positive. Majority of donors with raised ALT had fatty liver on biopsy with only 6 donors having significant findings of chronic persistent hepatitis and cirrhosis. Serologically, most of the donors (74.5%) with raised ALT had no markers of Hepatitis A, Hepatitis B, CMV or EBV. An interesting finding is the high incidence (18%) of positive, Anti HBc (IgM) in donors with raised ALT.

Liver biopsies from psoriatics treated with methotrexate.

To study the effects of Methotrexate (MTX) on the liver, light microscopic examination of liver biopsies from 18 consecutive patients with moderate to severe psoriasis receiving MTX seen between 1981-1985, were carried out. All patients received MTX (mean dosage of 1808 gm, mean duration of 88 months) prior to biopsy. There were 12 males, 6 females, with mean age of 55.1 yrs (range 39-77 yrs). All patients were HBsAg negative, non diabetic, and with no significant drug history or alcohol intake. Twenty liver biopsies were examined. Attempts to correlate severity of histological changes to dosage and duration of MTX therapy; and to the levels of raised SGPT at biopsy, failed to show any definite relationship. A variety of histological changes were seen in liver biopsies of MTX treated psoriatics, with 2 patients showing progression of histological changes following repeat biopsy.

The pattern of hydatidiform moles in Singapore.

Hydatidiform mole is common in Singapore, and the the incidence of malignant trophoblastic neoplastic neoplasia is significantly higher than in Western countries. Within a 10-year period (1968-1977), 538 cases of hydatidiform mole were diagnosed. On retrospective study, 498 (92.6%) were considered to be complete and 40 (7.4%) partial. The ratios of complete to partial moles were similar for the major population groups. In the present study, only complete moles were found to give rise to persistent trophoblastic disease. The lack of such association in partial hydatidiform moles is in keeping with their known low malignant potential. Occasional abnormal post-evacuation hCG curves, however, are being described from other centres, and while the underlying pathology remains largely undocumented, partial moles have to be dealt with on an empirical basis in the light of the hCG follow-up levels.
