| Popis: | Rapid diagnosis of tuberculous meningitis (TBM) is crucial as the disease outcome depends on the stage at which the treatment is initiated. The reliability of the available tests has not been established; thus, the present study was conducted to evaluate the conventional diagnostic tests as compared to the newer methods. Cerebrospinal fluid was collected from 100 children, and analyzed for various biochemical and cytological tests. The samples were subjected to Ziehl-Neelsen (Z-N) staining, Lowenstein-Jensen (L-J) culture, BACTEC culture and polymerase chain reaction (PCR). Twenty-two patients could be identified as definitive TBM based on the demonstration of Mycobacterium tuberculosis by BACTEC culture and PCR. Of these 22 cases, Z-N staining was positive in only two and L-J culture in six cases. Both the BACTEC culture and PCR had 100% agreement in the diagnosis of TBM. However, BACTEC culture could be a better diagnostic test as drug sensitivity can also be performed by this method. |
