BACTERIOLOGICAL PROFILE OF PATIENTS WITH ACUTE PYOGENIC MENINGITIS - A HOSPITAL BASED STUDY
Journal Title: Journal of Evidence Based Medicine and Healthcare - Year 2016, Vol 3, Issue 19
Abstract
BACKGROUND Pyogenic meningitis is one of the most common infectious disease emergencies involving the central nervous system with higher incidence in developing countries than developed nations. Despite the large number of pathogens that have been reported to cause acute pyogenic meningitis, certain microorganisms are isolated with higher frequency depending on patient’s age, immune status and geography. Present study was aimed to determine the trends in aetiology and spectrum of the bacteriological profile in adult patients with suspected pyogenic meningitis in North-East India. MATERIALS 50 CSF samples from as many patients of Acute Bacterial Meningitis over a period of one year were processed for cell counts, biochemical analysis, gram staining, culture, antigen detection by latex agglutination test and antibiotic susceptibility tests, as per standard techniques. OBSERVATION CSF cell counts showed neutrophilic predominance in all cases along with high protein and low sugar levels. 44% of the cases were culture positive and latex agglutination test was positive in 46.4% of the cases where culture was negative. S. pneumonia was the predominant pathogen identified in the present study in 12(24%) cases, followed by Pseudomonas and E. coli in 5(10%) cases each. Gram stain indicated the causative organisms in 68.2% of the culture positive cases. Among the culture negative patients gram stain indicated the causative organism in 3(10.7%) cases and these three cases were positive by LAT also. CONCLUSION Simple, rapid, inexpensive tests like gram staining remain significant means for diagnosis of acute pyogenic meningitis in developing countries. LAT goes a long way in identifying the organisms where the cultures are negative. This study thus paves the way for larger studies in this region for better recognition of the predominant organisms and the empirical antibiotic regimens.
