Predictors of first-line antiretroviral therapy failure amongst HIV-infected adult clients at Woldia Hospital, Northeast Ethiopia.

ABSTRACT: Due to the limited availability of viral load testing for treatment outcome monitoring in resource limited settings, identifying predictive factors of antiretroviral treatment failure will help in selecting clients who will benefit most from the targeted use of viral load monitoring. Little is known about the predictors of treatment failure in the study area. This study was conducted to determine factors that predict first-line antiretroviral therapy failure among HIV-infected adult clients at Woldia Hospital, Northeast Ethiopia. For this study, antiretroviral therapy treatment failure was defined as the fulfillment of clinical and/or immunological criteria set by WHO.Case-control study was carried out from November to December 2014. Cases were adult clients who were on failing first line regimen and on active follow up while controls were those adult clients on a non-failing first-line regimen for 36 months and above and on active follow up. Data was entered in to Epi Info version 7 and was exported to SPSS version 20 for analysis. Binary logistic regression model was used to identify predictors of ART failure.A total of 59 cases and 245 controls were included in the analysis. Sixty three percent of the participants were females and the median age at ART enrollment was 33 years (IQR; 28, 40). The median baseline CD4count was not significantly different among cases and controls (105 (IQR = 60-174)vs.131 (IQR = 72.5-189.0); p = 0.301). The median peak CD4 count in the failure group (230 (IQR = 123-387)) was significantly low compared to the non-failure group (463 (IQR = 348.5-577)) [p < 0.001]. High peak CD4count (AOR = 0.993; 95% CI 0.990, 0.996) and longer duration on ART (AOR = 0.923; 95% CI 0.893, 0.954) were protective of treatment failure. In addition stavudine based regimen (AOR = 3.47; 95% CI 1.343, 10.555), low baseline BMI (AOR = 2.75; 95% CI 1.012, 7.457), unemployment (AOR = 4.93; 95% CI 1.493, 16.305) and formal educational level (AOR = 5.15; 95% CI 1.534, 17.276) were independently significant predictors of treatment failure.In this setting low peak CD4count, shorter duration on first line ART, d4T based regimen, low baseline BMI, unemployment and formal educational level were significantly associated with increased treatment failure. Retaining patients on their initial first line regimen with appropriate follow up and improving their socioeconomic status through various livelihood initiatives should be strengthened.

Project description:BackgroundTreatment failure defined as progression of disease after initiation of ART or when the anti-HIV medications can't control the infection. One of the major concerns over the rapid scaling up of ART is the emergence and transmission of HIV drug resistant strains at the population level due to treatment failure. This could lead to the failure of basic ART programs. Thus this study aimed to investigate the predictors of treatment failure among adult ART clients in Bale Zone Hospitals, South east Ethiopia.MethodsRetrospective cohort study was employed in four hospitals of Bale zone named Goba, Robe, Ginir and Delomena. A total of 4,809 adult ART clients were included in the analysis from these four hospitals. Adherence was measured by pill count method. The Kaplan Meier (KM) curve was used to describe the survival time of ART patients without treatment failure. Bivariate and multivariable Cox proportional hazards regression models were used for identifying associated factors of treatment failure.ResultThe incidence rate of treatment failure was found 9.38 (95% CI 7.79-11.30) per 1000 person years. Male ART clients were more likely to experience treatment failure as compared to females [AHR = 4.49; 95% CI: (2.61-7.73)].Similarly, lower CD4 count (<100 m3/dl) at initiation of ART was found significantly associated with higher odds of treatment failure [AHR = 3.79; 95% CI: (2.46-5.84).Bedridden [AHR = 5.02; 95% CI: (1.98-12.73)] and ambulatory [AHR = 2.12; 95% CI: (1.08-4.07)] patients were more likely to experience treatment failure as compared to patients with working functional status. TB co-infected clients had also higher odds to experience treatment failure [AHR = 3.06; 95% CI: (1.72-5.44)]. Those patients who had developed TB after ART initiation had higher odds to experience treatment failure as compared to their counter parts [AHR = 4.35; 95% CI: (1.99-9.54]. Having other opportunistic infection during ART initiation was also associated with higher odds of experiencing treatment failure [AHR = 7.0, 95% CI: (3.19-15.37)]. Similarly having fair [AHR = 4.99 95% CI: (1.90-13.13)] and poor drug adherence [AHR = 2.56; 95% CI: (1.12-5.86)]were significantly associated with higher odds of treatment failure as compared to clients with good adherence.ConclusionThe rate of treatment failure in Bale zone hospitals needs attention. Prevention and control of TB and other opportunistic infections, promotion of ART initiation at higher CD4 level, and better functional status, improving drug adherence are important interventions to reduce treatment failure among ART clients in Southeastern Ethiopia.

Project description:BackgroundEarly initiation of antiretroviral therapy (ART) reduces the development of acquired immunodeficiency syndrome (AIDS), non-AIDS related comorbidities and mortality, and prevents transmission. However, the prevalence of delayed ART initiation amongst prisoners in sub-Saharan African countries is high and the contributing factors to this are relatively unknown.MethodsQualitative interviewing was employed to understand the prisoners' lived world with regard to initiating ART and associated barriers and facilitators in the South Ethiopian prison system. We interviewed seven (five male and two female) inmates living with HIV (ILWH) and eleven stakeholders who had a role in human immunodeficiency virus (HIV) care provision for incarcerated people. A phenomenological approach was used to analyse the interview data in which meaning attributed to the lived experiences of the participants was abstracted.ResultsIn this study, participants discussed both barriers to, and facilitators of, early ART initiation during incarceration. The barriers included a lack of access to voluntary counselling and testing (VCT) services, poor linkage to care due to insufficient health staff training, uncooperative prison security systems and loss of privacy regarding disclosure of HIV status. Insufficient health staff training and uncooperative prison security systems both contributed to a loss of patient privacy, ultimately resulting in treatment refusal. Although most participants described the importance of peer education and support for enhancing HIV testing and treatment programs amongst prisoners, there had been a decline in such interventions in the correctional facilities. Service providers suggested opportunities that a prison environment offers for identification and treatment of HIV infected individuals and implementation of peer education programs.ConclusionsOur study identified crucial barriers to and facilitators of early ART initiation amongst prisoners, a key HIV priority population group. Interventions that address the barriers while strengthening the facilitators may enhance a greater utilisation of ART.

Project description:BackgroundContemporary data on the immunologic, haematologic and virologic responses and predictors of virologic failure after initiation of free antiretroviral treatment in Cameroon are needed to evaluate the current treatment-monitoring algorithm and to complement efforts to scale-up and improve on the management of HIV infections.MethodsThis was a cross-sectional study conducted between October 2010 and June 2012. A total of 951 participants aged 18-74 years were recruited from selected approved HIV treatment centres of the Northwest and Southwest regions. This comprised 247 males and 704 females. Demographic, self-reported risk behaviours and socioeconomic data were obtained using a structured questionnaire. Full blood and CD4 + T-cell counts were done using standard automated techniques. Determination of viral load (VL) was done using Abbott RealTime HIV-1 m2000™ system. Data was analysed using SPSS version 17. The statistical significance level was P < 0.05.ResultsThe median duration of antiretroviral therapy (ART) was 24 months. The population mean CD4 + T-cell count was 255.3 cells/μL [95% CI, 236.8 - 273.9]. Overall, 45.9%, 43.8% and 10.2% of the participants had CD4 + T-cell counts of < 200 cells/μL, 200-499 cells/μL and > 500 cells/μL respectively. Anaemia was present in 26.2% of the participants with 62.3%, 25.7% and 12% described as mild, moderate and severe anaemia respectively. Virologic failure occurred in 23.2% of the participants with 12.3% having VL > 10,000 RNA copies/mL. Meanwhile 76.8% of patients attained adequate viral suppression with 40.8% having undetectable viral load. The age group 18-29 years (p = 0.024), co-infection with tuberculosis (p = 0.014), anaemia (p = 0.028) and distance from the treatment centre (p = 0.011) independently predicted virologic failure.ConclusionThe majority of the participants achieved adequate viral suppression after ≥ 6 months of ART. Despite these favourable immuno-haematologic and virologic outcomes, the National AIDS Control Program should step-up efforts to improve on antiretroviral drug distribution, as well as proper assessment and management of anaemia, foster early diagnosis and treatment of tuberculosis and enhance treatment adherence counselling especially in younger patients.

Project description:BackgroundOpportunistic infections (OIs) are illnesses that attack people with weakened immune systems, such as HIV patients, more frequently and severely. The majority of opportunistic infections (OIs) are the leading causes of morbidity and mortality in HIV/AIDS patients, emerging at the end of the illness. The objective of this study was to assess the incidence and risk factors of opportunistic infections (OIs) in HIV-infected children receiving antiretroviral therapy in public hospitals in Northeast Ethiopia.MethodsA multicenter retrospective follow-up study was undertaken at public hospitals in northeast Ethiopia from September 1, 2010, to January 30, 2022. A total of 341 HIV-infected children on antiretroviral therapy were included in the study. Data was entered using Epi-Data Manager version 4.6.1, and it was analyzed using STATA version 16.1. The opportunistic infection free-survival time was estimated using the Kaplan-Meier survival curve. Bivariable and multivariable Cox proportional hazard models were used to investigate the determinants of opportunistic infections.ResultsThe overall incidence rate of opportunistic infections (OIs) was 6.0 (95% CI: 5.0-7.1) per 100 child-years of observation. This study's participants were observed for a minimum of 9 months and a maximum of 122 months, for a total of 21,629 months, or 1802.4 years. Children with WHO clinical stages III and IV (AHR: 1.77; 95% CI: 1.13, 2.77), non-users of Cotrimoxazole Preventive Therapy (CPT) (AHR: 2.10; 95% CI: 1.40, 3.08), and low hemoglobin levels (10 mg/dl) (AHR: 1.88; 95% CI: 1.25, 2.82) were identified as significant predictors of opportunistic infection.ConclusionIn this study, the incidence rate of opportunistic infections among HIV-infected children was found to be high when compared to other studies. Low hemoglobin levels (10 mg/dl), low CD4 counts or percentages, clinical stages III and IV, and non-users of CPT were all associated with higher rates of opportunistic infection.

Project description:BackgroundAlthough antiretroviral therapy has significantly altered the natural history of human immunodeficiency virus infection and improved the quality of life of patients, there are conflicting reports regarding its impact on hematological outcomes. Thus, this study aimed at investigating the prevalence and predictors of anemia among adults on antiretroviral therapy in Northeast Ethiopia.Materials and methodsA retrospective cohort study was carried out among adults who began antiretroviral treatment between September 2005 and January 2019 at two governmental hospitals in Dessie town. Data were collected from patients' medical records using a pretested data extraction instrument. Anemia was the primary outcome variable of the study. It was defined based on WHO criteria after adjustment for altitude and smoking status of measured values. Data were entered and validated using EpiData Version 3.1 and then exported to SPSS Version 20.0 for analysis. Descriptive analysis was done for prevalence and binary logistic regression was carried out to assess whether covariates were associated with experiencing anemia. Statistical significance has been considered at p-value <0.05.ResultsMedical records of 392 patients (mean age: 35.58 ± 9.46 years) were reviewed. Of the total 392 patients, 218 (55.6%) were females, 261 (66.6%) were categorized under WHO clinical stage III/IV and 134 (34.2%) had a baseline CD4 cell count of <100 cells/mm3. The mean baseline CD4 cell count was 179 cells/mm3 (range: 2 to 853 cells) and 230 (58.7%) of the participants were on zidovudine-based regimen. Anemia was diagnosed among 162 (41.3%) patients. After adjustment for other confounding factors, risk of anemia was significantly associated with low baseline CD4 cell count (AOR 1.80, 95% CI 1.05-3.06) and tenofovir based regimen (AOR 2.05, 95% CI 1.31-3.21). On the other hand, being educated was found to be protective (AOR 0.40, 95% CI 0.21-0.78).ConclusionIn this research, the prevalence of anemia was relatively high. Low baseline CD4 cell count and tenofovir based regimen were independent predictors of anemia; while being educated was protective. Treatment programs should focus on early diagnosis and treatment of HIV as well as routine screening and proper treatment of anemia.

Project description:BackgroundHuman immunodeficiency virus (HIV) infection is a major public health concern globally, especially in sub-Saharan African countries. Even though determining the incidence of treatment failure and its predictor is a crucial step to reduce the problem, there is limited information indicating the incidence and predictors of treatment failure among children in Ethiopia. Therefore, this study was conducted to assess the incidence and predictors of treatment failure among children on first-line antiretroviral therapy (ART) in Amhara Region referral hospitals, Northwest Ethiopia.MethodsAn institution-based retrospective follow-up study was conducted from January 30, 2011, to January 30, 2018. A total of 402 children on first-line antiretroviral therapy were selected with a simple random sampling method in Amhara Region Referral Hospitals, Northwest Ethiopia. Data were extracted by reviewing patients' ART intake and follow-up forms using pretested and structured checklists. The collected data were entered into Epidata Version 4.2 and analysis was done using STATA Version 13. Bivariable and multivariable Cox proportional hazards regression models were fitted to identify predictors of treatment failure.ResultsA total of 402 records of children on antiretroviral therapy (ART) were reviewed and treatment failures rate within the follow-up period were 12.19% (95% CI: 8.5, 15.88). This study also found that the overall incidence density rate was 3.77% per 100 person-years observation. Virologic failure accounts 48.98% followed by immunologic (28.57%) and mixed failures (22.44%). Poor ART adherence (AHR: 4.6, 95%CI: 1.61, 13.20), drug regimens, AZT-3TC-NVP (AHR: 5.2, 95%CI: 1.9, 14.26), and AZT-3TC-EFV (AHR: 6.26, 95% CI: 1.88, 20.87), Children whose both parent were died (AHR: 2.8, 95%CI: 1.07, 7.37) and world health organization (WHO) clinical stage-4 (AHR: 2.95, 95%CI: 1.04, 8.366) were found to be predictors for treatment failure among children.ConclusionThe proportion of treatment failure among children on first-line ART in Amhara Region referral hospitals, Northwest Ethiopia was found to be high. Nearly half of the children experienced Virologic failure. Poor ART adherence, children whose parents`died without parents, WHO clinical stage-4 at baseline and type of regimen patients took were found to be predictors of first-line ART treatment failure. Therefore, expanding access to routine viral load, CD4 and clinical monitoring is mandatory to detect and early intervene of treatment failures' to improve outcomes for children on ART. Patient caregivers or parents should strictly support children on medication adherence. Training to health professionals should be given time-based on revised guidelines, and follow up of treatment outcome should be monitored nationally to take the appropriate intervention.
