Outpatient drug-induced parenchymal liver disease requiring hospitalization.

A case-history study of drug-induced liver disorders requiring hospitalization was carried out at the Group Health Cooperative of Puget Sound, a health maintenance organization with about 280,000 members, for the five-year period from January 1, 1977 to December 31, 1981. During this time, there were 12 instances of hospitalization for liver disorders judged to be probably (nine cases) or possibly (three cases) attributable to outpatient drug ingestion (other than antitumor agents). The rate was on the order of one per 100,000 person-years at risk. Drugs implicated as probable causes were ampicillin (two cases), carbamazepine (one case), erythromycin (one case), methyldopa (one case), sulfasalazine (one case), quinidine (one case), trimethoprim/sulfamethoxazole (one case), and multiple drugs (one case).

Long-term follow-up study of cimetidine.

In a 5-year follow-up study of 8553 recipients of cimetidine at Group Health Cooperative of Puget Sound, we examined the frequency of uncommon serious illness requiring hospitalization that may have been drug induced. With the possible exception of one patient with probable drug-induced liver disease, we did not find any instances of serious illness requiring hospitalization that could be attributed with reasonable certainty to cimetidine. This large study provides reassurance that cimetidine is a relatively safe medication.

Certain nonsteroidal antiinflammatory drugs and hospitalization for upper gastrointestinal bleeding.

In this follow-up study we attempted to estimate the risk of hospitalization for upper gastrointestinal bleeding (exclusive of bleeding from duodenal ulcer) caused by taking certain nonsteroidal antiinflammatory drugs (NSAIDs) in people below the age of 65 years. The final figures represent our best estimate, taking into account all of the available information, and suggest that NSAIDs (excluding aspirin) rarely cause gastrointestinal bleeding from the stomach that requires hospitalization in this age group. A formal analysis of the data according to classic techniques was not feasible since numerous important confounding factors could not be controlled. Indeed, the results indicated that such formal analysis is unnecessary. The data as they stand are of considerable value in providing a reasonable estimate of attributable risk for the drugs studied.
