Clinical Status of Lactate Dehydrogenase Activity in Cerebrospinal Fluid with Age and Sex Distribution in Different Types of Meningitis

Aim: The cerebrospinal fluid concentrations of Lactate dehydrogenase (LDH) were studied in patients with pyogenic, tubercular and viral meningitis in different age and sex group. Material and methods: A total of 160 cases, aged between 1 month and 60 years, including patients with bacterial meningitis (n=50), pyogenic meningitis (n=46), viral meningitis (n=24) and a control group (n=40), were analyzed on the basis of data from the initial clinical examinations. Results:Significant increase in LDH level (P<0.001) were observed in the test group when compared to the control group. Bacterial meningitis is more common than non bacterial meningitis. Pyogenic meningitis is more prevalent under 1 year of age group while tuberculous meningitis is seen most frequently betweens 3 to 5 year of age. Conclusion:The maximum prevalence of different types of meningitis was in the age group of 1 to 10 years age. The LDH level did rise quite significantly in pyogenic meningitis.
