Socio-clinico-radiological profile of smear-positive pulmonary tuberculosis patients in association with sputum conversion and baseline hsCRP levels.

Our was an observational follow-up study where the aim was to assess the baseline high-sensitivity C-reactive protein levels in 50 smear-positive pulmonary tuberculosis patients in association with socio-clinico-radiological profile and microbiological conversion. Smear and culture conversion of sputum samples at the end of intensive phase of anti-tubercular treatment were recorded. Baseline serum high-sensitivity C-reactive protein estimation was done by ELISA. Mean high-sensitivity C-reactive protein levels at baseline, smear/culture converted and delayed converters were 68.1 ± 22.2 mg/l, 66.7 ± 22.0 mg/l and 91.6 ± 6.7 mg/l, respectively; high-sensitivity C-reactive protein levels were significantly higher in delayed converters as compared to sputum converters. Significantly higher baseline high-sensitivity C-reactive protein levels were seen in patients with bilateral chest X-ray lesions, cavitations, evening rise of temperature, haemoptysis and dyspnoea as compared to those without these features. high-sensitivity C-reactive protein, being a non-specific inflammatory marker could be an adjunct tool for TB prognosis.
