Diagnosis of tuberculosis in an era of HIV pandemic: a review of current status and future prospects.
HIV and tuberculosis co-infection interact in fundamentally important ways. This interaction is evident patho-physiologically, clinically and epidemiologically. There are several differences between HIV-infected and HIV-uninfected patients with tuberculosis (TB) that have practical diagnostic implications. TB is more likely to be disseminated in nature and more difficult to diagnose by conventional diagnostic procedures as immunosuppression progresses. As TB rates continue to increase in HIV-endemic regions, improved diagnostic techniques merit consideration as TB-control strategies. There is a need to develop more user friendly techniques, which can be adapted for use in the high-burden and low-income countries. This review focuses on the diagnostic challenges in HIV-TB co-infection with an update on the current techniques and future prospects in an era of HIV pandemic.
