ABSTRACT
Urinary lipoarabinomannan [LAM] detection is a promising approach for the rapid diagnosis of active tuberculosis [TB]. To assess the diagnostic accuracy of urine LAM among TB patients either pulmonary or extra pulmonary. This study was carried out on 85 cases [46 male and 39 female] with active tubercular infection divided into three groups; pulmonary [n = 40], extra pulmonary [n = 30] and disseminated tuberculosis [n = 15]. Twenty-five normal individuals were included as the control group. LAM level was measured in urine by enzyme-linked immunosorbant assay [ELISA]. TB Patients with disseminated disease had a higher urine LAM level [1.75 +/- 1.65 ng/ ml] than that for patients with pulmonary [0.58 +/- 0.53 ng/ml] or extra pulmonary TB [0.17 +/- 0.1 Ing/ml] [P < 0.001]. Patients with smear positive specimens had a higher urine LAM level [0.63 +/- 0.54 ng/ml] than that of smear negative [0.040 +/- 0.06 ng/ml] [P < 0.001]. Quantitative urine LAM test results positively correlate with the degree of bacillary burden. Advanced age, immunosuppressant state and advanced radiological lesion were significant factors that were associated with higher quantitative urine LAM [P < 0.05]. Urine LAM test is a simple, rapid, and reliable diagnostic modality for active pulmonary or extra pulmonary tuberculosis. Quantitative LAM detection results increasedprogressively with bacillary burden and immunosuppression. Patients with disseminated TB are target populations for urine LAM detection
