Background: Achieving the long terms goals of antiretroviral treatment (ART) requires a careful approach during treatment initiation that takes into account patient’s psychosocial state, availability and accessibility of treatment combinations, and adherence support. Adverse drug reactions that occur during the initial phases have a bearing on treatment outcomes and thus need to be monitored and treated. Objective: This study was done to assess length of time (survival time) it took for clinically significant adverse drug reactions to occur in patients taking Nucleoside Reverse Transcriptase Inhibitors (N(t)RTI) available for treatment of Human Immunodeficiency Virus (HIV) infection in Zimbabwe. Methods: A retrospective cohort of patient data collected from January 2009 to December 2012 was extracted from an Electronic Health Record database. Data from patients who were initiated on antiretroviral (ARV) drug regimens containing N(t)RTI drugs were analysed for survival time. A sample of 205 patient files was extracted for the time period for survival analysis using adverse drug reactions due to N(t)RTI drugs. Results: After data extraction, a total of 205 patient records were used in determining the time to event analysis of ADR’s in the cohort. The age range for the patients included in the study was 9 - 76 with a mean of 41 years (s.d = 14.8). Patients initiated on stavudine had a lower survival time before a clinically significant ADR compared to tenofovir (-365 days, p-value < 0.0005). Patients on zidovudine also had a less time before a significant reaction compared to those on tenofovir (-230 days;p-value = 0.008). Patients on zidovudine fared better compared to those on stavudine (-134 days;p-value < 0.0005). The mean survival time was highest for tenofovir (618 days), followed by zidovudine (388 days), and then stavudine (254 days).Conclusion: Patients on tenofovir have a longer survival time before a clinically significant adverse reaction. Treatment programmes need to continue commencing patients on

Contexte:?The fight against HIV/AIDS epidemics is one of the greatest challenges of this century. The epidemic affects generally under-developed countries, and Sub-Saharan Africa are the most concerned. The combined marketed form known as Triomune was used as first-line treatment in several sub-Saharan African Countries (60% of VIH infected people), including Chad. However, no evaluation has been done for that treatment in the country. Objective: To evaluate the efficacy and safety immuno-virological of Triomune at the General Hospital in N’Djamena/Chad. Methods: 48 HIV-1 positive patients eligible for ARV treatment were enrolled in our study, and they have been then followed for 8 months. We have measured in these patients the CD4 cell count before treatment and at the 8th month of treatment. After 8 months of treatment, we have also evaluated the Lymphocyte T CD4 and the plasma viral load (VL). Comparisons of means of CD4 lymphocytes and plasma CV (≥1000 copies/ml) were used to define treatment failure.?Results:?48 patients were under Triomune regime. The average CD4 count was decreased from 462 ± 179.22 [56 - 981] cells/mm3?before treatment to 327.23 ± 153.77 [10 - 1008] cells/mm3?at the 8th month of treatment. The mean plasma viral load for patients was 66008.62 copies/ml. The failure rate to Triomune was 43.75% (21/48).?Conclusion:?Aside from the side effects already described for Triomune, our study reveals a high treatment failure rate. Hence, there is the need of regular revisions of therapeutic regime administer in the first intention.
