Abstract

OBJECTIVE:

To evaluate the prevalence, associated factors, and time-course changes of abnormal liver enzyme serum levels in adult patients with Salmonella enteritidis enterocolitis.

METHODS:

The clinical records of 104 patients (age range 15-86 years, 46.2% males) admitted to hospital because of S. enteritidis enterocolitis were reviewed. The prevalence of abnormal liver enzyme levels was evaluated, as well as its possible relationship to data of systemic inflammatory response, severe sepsis, and bacteremia. In addition, time-course changes in serum levels of liver enzymes were studied in 16 cases with available follow-up after hospital discharge.

RESULTS:

In patients without a pre-existing cause for liver enzyme abnormalities (n = 84), the prevalence of serum AST elevation was 23.0% (95% CI 15.4-34.5%), of serum ALT elevation was 17.9% (95% CI 0.6-20.0%), and of GGT elevation was 19.0% (95% CI 11.6-29.3%). The prevalence of abnormality for any of these enzymes (AST, ALT, or GGT) was 35.7% (95% CI 25.7-46.8%). The prevalence of altered serum alkaline phosphatase was lower. Alteration in liver enzyme serum levels was moderate in the majority of cases, and was found in association with the presence of fever. Serum enzyme levels decreased during the convalescence period after hospital discharge.

CONCLUSIONS:

Abnormalities in liver enzyme levels are frequent during severe enterocolitis due to S. enteritidis in adult patients. These abnormalities are moderate and self-limited.
