Serum pancreatic enzymes in HIV-seropositive patients.
Serum concentrations of trypsin and elastase I were determined in 109 HIV Ab-positive patients (52 asymptomatic HIV-infected patients, 25 with lymphadenopathy syndrome, and 32 with acquired immunodeficiency syndrome) to assess the prevalence of possible pancreatic damage in these patients. Serum trypsin was abnormally elevated in 46 of the 109 patients (42.2%): 19 of the 52 asymptomatic HIV-infected patients (36.6%), 9 of the 25 with lymphadenopathy syndrome (36%), and 18 of the 32 with acquired immunodeficiency syndrome (56.3%). Serum elastase 1 was elevated in 14 of the 109 HIV Ab-positive patients (12.8%): 3 of the 52 asymptomatic HIV-infected patients (5.8%), 3 of the 25 with lymphadenopathy syndrome (12%), and 8 of the 32 with acquired immunodeficiency syndrome (25%). None of the patients with abnormally high serum pancreatic enzyme concentrations had clinically evident pancreatic disease. There was no statistically significant difference in serum levels of trypsin and elastase I between drug addicts and nonaddicts, between alcoholics and nonalcoholics, or between those with cytomegalovirus infection and those without. A significant inverse relationship was found between serum enzyme concentrations and the number of CD4+ lymphocytes. The results of this study show that high levels of serum trypsin and elastase are present in an elevated percentage of patients with acquired immunodeficiency syndrome, suggesting that the pancreas is frequently damaged in this disease. The finding of abnormally high serum enzyme concentrations not only in patients with AIDS, but also in asymptomatic carriers and in patients with lymphadenopathy syndrome suggests an association between HIV infection and the development of pancreatic lesions.
