Hyperamylasaemia in asymptomatic HIV patients.

We studied serum amylase and its isoenzymes prospectively in 163 consecutive asymptomatic patients, 149 men and 14 women, infected with HIV and attending an HIV out-patient clinic. Six patients were receiving dideoxyinosine (DDI), a drug known to cause pancreatitis. No patient, however, had clinical signs suggestive of pancreatitis. Serum total amylase was increased in 39 of 163 patients (24%), in 11 of whom (28%), this was due to increased pancreatic (P) isoamylase alone, in 17 (42%) it was due to salivary (S) type alone and in six (17%) it was due to increase of both P and S fractions. In five patients (13%), macroamylase was detected. Pancreatic amylase was elevated in four of the six patients on DDI. The remaining two had macroamylase. Our results show that asymptomatic hyperamylasaemia is a common finding in HIV patients and that it appears to be heterogenous, i.e. elevation may be due to increase in P or S, both enzyme fractions or macroamylase. The high incidence of macroamylasaemia in HIV patients was an unexpected finding.
