The novel urine LAM point-of-care strip test offers potential clinical utility to improve TB diagnosis in HIV co-infected patients. Urine LAM strip test performance improves with increasing illness severity and more advanced immunosuppression, thus offering the greatest potential utility in hospitalised HIV-infected patients with advanced immunosuppression (CD4 cell count less than 200). However, in the context of high rates of empiric treatment and the availability of other novel TB diagnostics, the clinical impact of the urine LAM strip test is unknown. This study will investigate the impact of the urine LAM strip test. The study hypothesis is that the urine LAM strip test, when combined with standard TB diagnostics (smear microscopy and culture) will significantly improve TB treatment-related outcomes (TB-related mortality, morbidity and length of hospital stay) in HIV-infected hospitalized patients when compared to standard TB diagnostics alone.

Primary Outcome Measures:
  • All-cause mortality [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
    All-cause mortality at 8-weeks after study enrollment

Secondary Outcome Measures:
  • Change in TB-related morbidity score [ Time Frame: Baseline and 8 weeks ] [ Designated as safety issue: No ]
    Comparative change in TB score between baseline and 8 weeks after enrollment

  • Change in Karnofsky performance index [ Time Frame: Baseline and 8 week ] [ Designated as safety issue: No ]
    Comparative changes in the Karnofsky performance index between baseline and 8 weeks following enrollment

  • Hospital length of stay [ Time Frame: Date of hospital discharge (max 8 weeks) minus date of admission ] [ Designated as safety issue: No ]
    This is the number of days of hospital admission for enrolled patients up to a maximum of 8 weeks post enrollment.

  • Diagnostic accuracy of urine LAM strip test [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
    Diagnostic accuracy (sensitivity, specificity, predictive values and likelihood ratios) of the urine LAM strip test using TB culture as the diagnostic reference standard

Estimated Enrollment: 2400
Study Start Date: January 2013
Estimated Study Completion Date: March 2015
Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: LAM plus standard care
Patients allocated to this study arm will receive urine LAM strip testing in addition to the standard TB diagnostic tools WHO approved and available at each site
Device: Urine LAM strip test
This is a point-of-care lateral flow strip test to detect the presence of lipoarabinomannan (LAM) in patient urine samples. Only patients with a grade 2-5 visual band intensity will be considered positive and commenced on treatment
Other Name: Determine TB urine LAM Antigen strip test
No Intervention: Standard care
Patients allocated to this study arm will receive standard TB diagnostics currently WHO approved and available at the study site
