Background: Body fluids are commonly used for diagnosis as sputum is not reliable in children. Hence it is essential to study efficacy of body fluids in comparison to GeneXpert which is a new diagnostic modality. Objectives of this study was to incidence of rifampicin resistance, HIV status and efficacy of fluid analysis among tuberculosis suspect pediatric cases.

Methods: Present study was hospital based cross sectional study carried out over a period of two years at Department of Pediatrics, ACPM Medical College and Hospital from February 2016 to January 2018 among children with suspected tuberculosis. Rifampicin resistance was determined by using GeneXpert. Body fluids like CSF, pleural fluid, gastric aspirate etc were analyzed and compared with GeneXpert results.

Results: Rifampicin resistance was present in 5 cases i.e. 3.3%. 15.15% Patients were HIV positive and in them 12 were GeneXpert positive with 1 Rif resistance. Different Fluid analysis showed maximum positivity with pleural fluid >TB Lymphadenitis >TBM. GeneXpert done on different body fluids showed extra case detection in different fluid analysis negative patients i.e. 28.6% extra case detection in CSF (2 cases), 87.9% in gastric aspirate (25 cases), 85.4% in induced sputum (35 cases), 14.3% in Lymph node aspirate (1 case), 50% in pleural fluid (2 case).

Conclusions: : Rifampicin resistance found in present study is alarming. Among body fluids, FNAC, CSF and pleural fluids can be used reliably for diagnosis of tuberculosis where GeneXpert is not available.
