Enzymatic determinations in cerebrospinal fluid (CSF) of aspartate aminotransferase (AST), lactic dehydrogenase (LDH), gammaglutamyl transpeptidase (GGT), creatine phosphokinase (CPK) and creatine kinase BB (CK-BB) were performed in 16 patients with aseptic meningitis (AM), in 25 children with bacterial meningitis (BM) and in 15 patients with meningism. The activity of AST and GGT was significantly higher in patients with BM on admission compared with those with AM and meningism (p < 0.05 and p < 0.005, respectively) and decreased with therapy. The highest concentration of AST and LDH appeared in patients with poor outcome as well as in those with ventriculomegaly on neurosonography (p < 0.05). The concentration of CK-BB increased in all patient groups on admission and remained higher on termination of therapy. The present study confirms the high activity of AST and GGT in BM patients in the CSF whereas the increased activity of AST and LDH reflects the extent of brain injury. Nevertheless, the prognosis for individual patients cannot be established on the basis of enzyme activity alone, but depends on several factors.

There is little information on the diverse infectious causes of jaundice and hepatitis in the Asiatic tropics. Serology (hepatitis A, B, C and E, leptospirosis, dengue, rickettsia), antigen tests (dengue), PCR assays (hepatitis A, C and E) and blood cultures (septicaemia) were performed on samples from 392 patients admitted with jaundice or raised transaminases (> or =x3) to Mahosot Hospital, Vientiane, Laos over 3 years. Conservative definitions suggested diagnoses of dengue (8.4%), rickettsioses (7.3%), leptospirosis (6.8%), hepatitis B (4.9%), hepatitis C (4.9%), community-acquired septicaemia (3.3%) and hepatitis E (1.6%). Although anti-hepatitis A virus (HAV) IgM antibody results suggested that 35.8% of patients had acute HAV infections, anti-HAV IgG antibody avidity and HAV PCR suggested that 82% had polyclonal activation and not acute HAV infections. Scrub typhus, murine typhus or leptospirosis were present in 12.8% of patients and were associated with meningism and relatively low AST and ALT elevation. These patients would be expected to respond to empirical doxycycline therapy which, in the absence of virological diagnosis and treatment, may be an appropriate cost-effective intervention in Lao patients with jaundice/hepatitis.
