Results: The confirmed causes of death were TB (39%), acquired immune deficiency syndrome
(AIDS)-related opportunistic infections other than TB (AOI) (29%), and other systemic
diseases which were neither TB nor AIDS-related opportunistic infections (nonTB-nonAOI)
(16%). The definitive cause could not be confirmed in the remaining 16% of deaths. After
starting the TB treatment, deaths caused by TB occurred earlier compared with deaths caused
by AOI, which occurred steadily throughout the course of TB treatment, whilst deaths caused
by non-TB-nonAOI increased gradually in later months
