Development and validation of a risk prediction model for lost to follow-up among adults on active antiretroviral therapy in Ethiopia: a retrospective follow-up study

This study was aimed at developing a risk score prediction model for bacteriologically confirmed tuberculosis (TB) among adults with HIV receiving antiretroviral therapy in Ethiopia. An institutional-based retrospective follow-up study was conducted among 569 adults with HIV on ART. We used demographic and clinical prognostic factors to develop a risk prediction model. Model performance was evaluated by discrimination and calibration using the area under the receiver operating characteristic (AUROC) curve and calibration plot. Bootstrapping was used for internal validation. A decision curve analysis was used to evaluate the clinical utility. Opportunistic infection, functional status, anemia, isoniazid preventive therapy, and WHO clinical stages were used to develop risk prediction. The AUROC curve of the original model was 87.53% [95% confidence interval (CI): 83.88-91.25] and the calibration plot ( P -value = 0.51). After internal validation, the AUROC curve of 86.61% (95% CI: 82.92-90.29%) was comparable with the original model, with an optimism coefficient of 0.0096 and good calibration ( P -value = 0.10). Our model revealed excellent sensitivity (92.65%) and negative predictive value (NPV) (98.60%) with very good specificity (70.06%) and accuracy (72.76%). After validation, accuracy (74.85%) and specificity (76.27%) were improved, but sensitivity (86.76%) and NPV (97.66%) were relatively reduced. The risk prediction model had a net benefit up to 7.5 threshold probabilities. This prognostic model had very good performance. Moreover, it had very good sensitivity and excellent NPV. The model could help clinicians use risk estimation and stratification for early diagnosis and treatment to improve patient outcomes and quality of life.

BackgroundPeople living with HIV/AIDS (PLWHA) are frequently confronted with severe social issues such as rejection, abandonment, criticism, and stigma. This would negatively affect their quality of life. Several studies have been conducted so far to assess factors affecting the health-related quality of life among people living with HIV/AIDS who are on antiretroviral therapy (ART) in Ethiopia. However, to our knowledge, there is no previous study that has summarized the results of the studies that investigated health-related quality of life (HRQOL) among PLWHA in Ethiopia. Therefore, the purpose of this review was to estimate the pooled prevalence of HRQOL and its association with social support among people living with HIV/AIDS (PLWHA) on ART in Ethiopia.MethodsA systematic search was carried out using several electronic databases (PubMed, Science Direct, Web of Science, and Cochrane electronic), Google Scholar, Google, and a manual search of the literature on health-related quality of life among people living with HIV/AIDS who are on ART. A Microsoft Excel data extraction sheet was used to extract pertinent data from an individual study. To assess the heterogeneity of primary articles, the Cochrane Q test statistics and the I2 test were carried out, and a random effects meta-analysis was used to estimate the pooled prevalence of HRQOL.ResultOut of the 493 articles reviewed, ten with a total of 3257 study participants were eligible for meta-analysis. The pooled prevalence of HRQOL among people living with HIV/AIDS who are on antiretroviral therapy in Ethiopia was 45.27%. We found that strong perceived social support was significantly associated with higher levels of subjectively perceived HRQOL. PLWHA who were on ART and had good social support were four times more likely to report higher HRQOL when compared to their counterparts [AOR = 4.01, 95% CI 3.07–5.23].ConclusionA substantial number of PLWHA had poor HRQOL in Ethiopia. Social support was significantly associated with HRQOL among people living with HIV/AIDS. Hence, it’s recommended to encourage suitable intervention at every follow-up visit, and psycho-social support is also warranted to improve the quality of life.

The effect of dolutegravir (DTG)-based regimens on reducing attrition from care among women enrolled in the prevention of mother-to-child transmission (PMTCT) care program is unknown. Therefore, this study aimed to compare the incidence of attrition among women exposed to DTG-based with those exposed to efavirenz (EFV)-based first-line antiretroviral therapy (ART) in Ethiopia. An uncontrolled before-and-after study was conducted involving 932 women (with 466 on EFV-based and 466 on DTG-based regimens) who were enrolled in the PMTCT care program from September 2015 to February 2023. The outcome variable was attrition (i.e., maternal death or loss to follow-up before their infants' final HIV status was determined). A Kaplan-Meier estimator was employed to estimate the probability of attrition. The Cox proportional hazards regression model was fitted to identify predictor variables. The adjusted hazard ratio (aHR) with the corresponding 95% confidence interval (CI) was calculated to examine the risk difference in the comparison groups. The cumulative incidence of attrition among women was 5.2% (3.0% for those placed in the DTG-based regimen arm and 7.3% for those placed in the EFV-based regimen arm). Women on DTG-based regimens had a 57% (aHR: 0.43; 95% CI: 0.23-0.80) lower risk of attrition from care compared to those on EFV-based regimens. Women who delivered their infants at home (aHR: 2.35; 95% CI: 1.14-4.85), had poor/fair adherence (aHR: 3.23; 95% CI: 1.62-6.45), had unsuppressed/unknown viral load status (aHR: 2.61; 95% CI: 1.42-4.79), and did not disclose their status to partners (aHR: 2.56; 95% CI: 1.34-4.92) had a higher risk of attrition from PMTCT care compared to their counterparts. The cumulative incidence of attrition among women receiving PMTCT care is optimal. In addition, the risk of attrition among women receiving DTG-based regimens is lower than that among women receiving EFV-based regimens. Thus, DTG-based first-line ART regimen supplementation should be sustained to achieve a national retention target of 95% and above.

Background: Treatment failure (TF) among patients receiving antiretroviral therapy (ART) against human immunodeficiency virus (HIV) impacts on treatment outcome and is becoming a public health concern globally. However, magnitude of TF and factors leading to it are poorly defined in the context of Ethiopia. Thus, the aim of this study was to determine the magnitude of TF and assess its determinants among HIV-infected patients on ART in Ethiopia. Methods: A prospective and retrospective study was conducted from March 2016 to 2017. Retrospective clinical and laboratory data were captured from patients’ medical record. Socio-demographics and explanatory variables of participants were collected using pre-tested structured questionnaire and study participants were followed for additional 6 month after baseline viral load has been done to classify virologic failure (VF). Multiple logistic regression was conducted to assess risk factors associated with TF. Statistical significance was set at P-value less than 0.05. Results: A total of 9,284 adults taking ART from a nationally representative 63 health facilities were included in the study. Viral Load Suppression (VLS) (VL1000 copies/ml at baseline of the study were re-suppressed after six months of enhanced adherence and counseling, leading TF among population on ART in Ethiopia to be 983 (11%). Immunologic and clinical failure was significantly improved from 21.5% and 16.5% at ART initiation to 576 (6.2%) and 470 (5.0%) at baseline of the study, respectively. Medication adherence, disclosure of HIV status, missed appointment to ART, history of ART exposure prior to initiation, residency and marital status had significant association with TF. Conclusions: The high level of VLS (88.1%) could explain the success of ART program in Ethiopia towards achieving the UNAIDS global target on viral suppression. TF among population taking ART in Ethiopia is still a public health concern, since 11% of virally failed population is maintained on failed first-line regimen. However, a significant improvement on immunologic and clinical outcome after ART initiation was maintained. Close follow-up of medication adherence, ensuring disclosure of HIV status, regular appointment follow-up to ART could significantly improve the treatment outcome of population on ART in Ethiopia.

Achieving viral load suppression is crucial for the prevention of complications and deaths related to HIV infection. Ethiopia has embraced the worldwide 95-95-95 target, but there is no national representative information regarding virological suppression. Therefore, this review aims to determine the pooled virological suppression rate and identify the pooled effect of contributing factors of viral suppression for HIV-positive patients on antiretroviral therapy in Ethiopia. We systematically searched websites and databases, including online repositories, to obtain primary studies. Two reviewers assessed the quality of the included articles using the Newcastle-Ottawa Scale appraisal checklist. Publication bias was checked using Egger's regression test, the heterogeneity of the studies was assessed using I2 statistics and Q statistics, and a sensitivity analysis was performed to identify any outlier results in the included studies. The Der Simonian Laird random-effects model was used to estimate the overall proportion of viral suppression, and STATA 17 statistical software was used for all types of analysis. A total of 21 eligible articles primarily conducted in Ethiopia using HIV program data were used for this quantitative synthesis. The overall pooled virological suppression rate was 71% (95% CI, 64%-77%). The pooled effects of poor adherence to ART (adjusted odds ratio [AOR], 0.33; 95% CI, 0.28-0.40), body mass index (18.5-24.9 kg/m2; AOR, 1.8; 95% CI, 1.37-2.36), disclosure (AOR, 1.41; 95% CI, 1.05-1.89), absence of opportunistic infection (AOR, 1.68; 95% CI, 1.43-1.97), and high baseline viral load count (AOR, 0.65; 95% CI, 0.52-0.81) were identified as significant predictors of viral suppression. The overall pooled percentage of virological suppression was low compared with the global target of viral suppression and the Ethiopian Public Health Institute report. Poor adherence, normal body mass index, disclosure, absence of opportunistic infection, and high baseline viral load count were factors contributing to viral suppression in Ethiopia. Responsible stakeholders should maximize their efforts to achieve the global target of virological suppression by addressing significant predictors.

IntroductionAttrition from antiretroviral therapy (ART) programmes is a critical challenge among children receiving care in resource-limited settings. Our objective was to determine the rates and predictors of attrition among children on ART in Ethiopia.MethodsBetween December 2014 and September 2016, we conducted a prospective cohort study in eight health facilities in Ethiopia. Eligibility criteria included age 3 months–14 years; being on ART for not more than a month. Outcome was attrition due to death and/or loss to follow-up. Predictor variables were child clinical and socio-demographic characteristics, and caregiver socio-demographic characteristics. We used Cox Regression analyses to examine the association between predictors and outcome.ResultsOf 309 children, 304 were included, 52% were male. Their median age was 9 years (Inter-quartile range, IQR, 6–12). At ART initiation, their median CD4 was 362 cells/mm3 (IQR 231–499); and 74.3% had WHO stage 1 or 2 disease. During 287.7 person-years of observation (PYO), 24 attritions were recorded, yielding an attrition rate of 8.3 per 100 PYO (95% CI 5.4–12.1). Of these, six children were reported dead, leading to a mortality rate of 2.1 per 100 PYO (95% CI 0.8–4.3). Eighteen were lost to follow-up (LTFU) leading to LTFU rate of 6.26 per 100 PYO (95% CI: 3.83–9.70). The majority, 14 (58%) of attrition occurred during the first six months of treatment.Age below three years [aHR] = 5.14 (95% CI: 2.07–12.96), rural residence (aHR = 3.97, 95% CI: 1.34–11.78) and baseline Hgb in g/dl < 10 g/dl [aHR] = 5.68 (95% CI: 2.03–6.23) predicted higher risk of attrition. Baseline Hgb < 10 g/dl (aHR = 16.63, 95% CI: 1.64–168.4) and WHO stage III or IV (aHR = 12.25, 95% CI: 1.26–119.05) predicted the death of the child. Higher attrition was documented among children of both biological parents alive and biologically related close family caregivers.ConclusionYounger children, those from rural areas, and children with anaemia were at higher risk of attrition, especially during the early months of treatment, and therefore should be prioritized during treatment follow-up. Further studies should examine underlying reasons for higher attrition.

The aim of this study was to evaluate HIV-1 drug resistance among patients failing first-line antiretroviral therapy in Ethiopia. A total of 699 adults infected with HIV (aged ≥15 years) who failed first-line Antiretroviral Therapy (ART) were recruited between 2017 and 2019 from 63 ART-providing sites in Ethiopia. Treatment failure was defined as patients with two consecutive viral loads (VLs) ≥1000 copies/mL within six months of follow-up. The pol gene region of HIV-1 was amplified and sequenced using an in-house assay of the Chinese Center for Disease Prevention and Control. The Stanford HIVDB v9.0 algorithm was used for identification of resistance mutations. Resistance mutations were characterized according to the 2019 International AIDS Society-USA mutation list. P values of <0.05 were considered statistically significant during multivariate analysis, which was done using SPSS v26.0 (SPSS Inc., Chicago, IL). Overall, HIV drug resistance (HIVDR) among patients failing first-line therapy in Ethiopia was 77.8%. Non-nucleoside/tide reverse transcriptase inhibitors (NNRTI) and NRTI resistance were 75.7% and 71.2%, respectively. Neverapine (NVP) and Efavirenz (EFV) accounted for 74.2% and 60.8% of HIVDR, respectively. About half (48.1%) of NRTI-associated mutations were responsible for Abacavir resistance, while 34% were responsible for multi-NRTI resistance. Mutations responsible for resistance to the commonly used EFV and NVP accounted for 62.9%, while resistance to Etravirine, Doravirine, and Rilivirine, which were not part of the country's ART program, were 37.1%, and can be explained by cross-resistance within the drug class. Protease Inhebitor(PI)associated resistance was detected in only 1.6% of the study's participants. The most common mutations identified were M184V (30.1%), K103N (18.7%), Y181C (13.6%), and K65R (12.1%). In a multivariate logistic regression analysis, predictors of HIVDR were prior ART exposure (adjusted odds ratio [AOR]=2.3; 95% confidence interval [CI]=1.8, 3.6), absence of HIV status disclosure (AOR=2.05; 95%CI=1.26, 3.35), CD4 count of ≤200 cells/mm3 (AOR=1.94; 95%CI=1.21, 3.12), and bedridden status (AOR=4.16; 95% CI=3.21, 5.16). The high-levels of HIVDR among patients with failure of first-line ART in Ethiopia calls for individualized HIVDR testing. Mutations associated with multi-NRTI and NNRTI cross-resistance may alert the program for considering drugs of higher genetic barrier targeting protease and other regions. Patients with low CD4 count and those who are bedridden should be given special attention for the potential development of HIVDR during clinical management.

IntroductionHuman immunodeficiency virus (HIV) infection results in a gradual depletion of immune function, particularly CD4 cells. The CD4 assessment plays a significant role in assessing treatment responses and clinical decision-making for patients on combination antiretroviral therapy (ART) in resource-limited settings. However, new data on CD4 count changes are scarce; the volatility of CD4 counts after initiation of ART over time remains largely uncharacterized. This study aimed to identify the predictors of CD4 changes over time among HIV-infected children who began ART in Amhara, Ethiopia.MethodsA retrospective follow-up study was performed. A total of 983 HIV-infected children who initiated ART in government hospitals in the Amhara region between 2010 and 2016 were included using a simple random sampling technique. Data were extracted using a structured checklist. An exploratory data analysis was carried out to explain individual and average profile plots. The linear mixed model was used to identify the CD4 change count predictors over time. Variables with p value < 0.05 were considered statistically significant in a multivariable linear mixed regression analysis.ResultsThe mean CD4 count of the participants was 465.1 cells/mm3 with an average CD4 count increase of 30.06 cells/mm3 over 6 months from baseline CD4 count and ART initiation. Childhood age (β = − 0.015; 95% Cl − 0.021, − 0.009), opportunistic infection at ART initiation (β = − 0.044, 95% CI − 0.085, − 0.004), hemoglobin level (β = 0.013; 95% CI 0.004, 0.022), and baseline WHO clinical stage II (β = − 0.046, 95% CI − 0.091, − 0.0003) were significant predictors of CD4 changes over time.ConclusionsThe average CD4 count increase was sufficient in HIV patients who began combined antiretroviral therapy over time. The younger age of the infant, the higher baseline level of hemoglobin, the baseline WHO clinical stage II, and opportunistic infections led to changes in CD4 counts. As a result, timely diagnosis and treatment of opportunistic infections will reduce the risk of opportunistic infections.

Loss to follow-up (LTFU) from antiretroviral therapy (ART) remains a major public health concern worldwide, including in Ethiopia. However, nationally representative pooled cohort data on LTFU among adults receiving ART are limited. To address this gap, we conducted a meta-analysis to estimate the incidence and identify predictors of LTFU among adults on ART in Ethiopia. This systematic review and meta-analysis adhered to the PRISMA guidelines. Relevant studies were identified through a comprehensive search of multiple databases, including PubMed, CINAHL, Scopus, EMBASE, and Google Scholar. Data analysis for pooled estimates of incidence and predictors was performed using STATA version 17 with the DerSimonian and Laird random-effects model. Heterogeneity was assessed using Cochrane’s Q-test and the I² statistic, while publication bias was evaluated using funnel plots and Egger’s test. Out of 1,245 studies identified, 24 met the inclusion criteria, comprising a total of 24,637 participants. The pooled incidence rate of LTFU among adults on ART was 8 per 100 person-years (95% CI: 7–10), and the pooled median time to LTFU was 27.77 months (95% CI: 19.22–36.32). Moreover, variation in study sample size (R² = 34.10%) contributed substantially to the high level of heterogeneity among the included studies. Predictors of LTFU included not receiving isoniazid prophylaxis (HR = 1.39, 95% CI: 1.30–1.49), fair or poor ART adherence (HR = 1.56, 95% CI: 1.49–1.64), WHO clinical stages III–IV (HR = 1.29, 95% CI: 1.21–1.38), undisclosed HIV status (HR = 1.34, 95% CI: 1.24–1.45), CD4 count < 200 cells/mm³ (HR = 1.28, 95% CI: 1.19–1.33), BMI < 18.5 kg/m² (HR = 1.34, 95% CI: 1.27–1.43), and age 15–24 years (HR = 1.31, 95% CI: 1.22–1.41). The median time to LTFU among adults on ART in Ethiopia was close to the national target, suggesting the need to enhance retention strategies. Targeted interventions should focus on young adults, undernourished patients, and those with poor adherence. Strengthening adherence support and preventive care, including isoniazid prophylaxis, is essential to improve ART retention outcomes.

Introduction Depression is the most common mental health problem in people living with the human immune virus. It ranges from 11% to 63% in low- and middle-income countries. Depression was high in people living with HIV/AIDS in developing countries, especially in the Ethiopian context. Even though depression has negative consequences on HIV-positive patients, the care given for depression in resource-limited countries like Ethiopia is below the standard in their HIV care programs. Method International databases (Google Scholar, PubMed, Hinari, Embase, and Scopus) and Ethiopian university repository online have been covered in this review. Data were extracted using Microsoft Excel and analyzed by using the Stata version 14 software program. We detected the heterogeneity between studies using the I2 test. We checked publication bias using a funnel plot test. Results The overall pooled depression prevalence among adult HIV/AIDS patients attending antiretroviral therapy in Ethiopia was 36.3% (95% CI: 28.4%, 44.2%) based on the random effect analysis. Adult HIV/AIDS patients having CD4count < 200(AOR = 5.1; 95% CI: 2.89, 8.99), widowed marital status (AOR = 3.7; 95% CI: 2.394, 5.789), medication nonadherence (AOR = 2.3; 95% CI: 1.63, 3.15), poor social support (2.986) (95% CI: 2.139, 4.169), perceived social stigma (2.938) (2.305, 3.743), opportunistic infections (3.010) (2.182, 4.151), and adverse drug reactions (4.013) (1.971, 8.167) were significantly associated with depression among adult HIV/AIDS patients on antiretroviral therapy, in Ethiopia. Conclusion and Recommendation. The pooled depression prevalence among adult HIV/AIDS patients attending antiretroviral therapy in Ethiopia was higher than the general population and is alarming for the government to take special consideration for HIV-positive patients. Depression assessment for all HIV-positive patients and integrating with mental health should be incorporated to ensure early detection, prevention, and treatment. Community-based and longitudinal study designs mainly focusing on the incidence and determinants of depression among adult HIV/AIDS patients should be done in the future.

Background: High rates of disease progression and HIV drug resistance (HIVDR) among adults taking highly active antiretroviral treatment (HAART) in Sub-Saharan Africa were previously documented. However, children were generally not considered despite their greater risk. Hence, this study was aimed to evaluate HIV-1 disease progression and drug resistance mutation among children on first-line antiretroviral therapy in Ethiopia. Method: A longitudinal study was conducted among 551 HIV-positive children (<15 years old) recruited between 2017 and 2019 at 40 antiretroviral treatment delivery sites in Ethiopia. Disease progression was retrospectively measured over a 12-year (2007-2019) follow-up as the progress towards immunosuppression. Two consecutive viral load (VL) tests were conducted in 6-month intervals to assess virologic failure (VF). For children with VF, HIV-1 genotyping and sequencing was performed for the pol gene region using in-house assay validated at the Chinese Center for Disease Control and Prevention, and the Stanford HIVDB v9.0 algorithm was used for identification of drug resistance mutations. The Kaplan-Meier analysis and Cox proportional hazards regression model were used to estimate the rate and predictors of disease progression, respectively. Results: The disease progression rate was 6.3 per 100 person-years-observation (95% CI = 4.21-8.53). Overall immunosuppression (CD4 count < 200 cells/mm3) during the 12-year follow-up was 11.3% (95% CI = 7.5-15.1). Immunosuppression was significantly increased as of the mean duration of 10.5 (95% CI = 10.1-10.8) years (38.2%) to 67.8% at 12 years (p < 0.001). Overall, 14.5% had resistance to at least one drug, and 6.2% had multi-drug resistance. A resistance of 67.8% was observed among children with VF. Resistance to non-nucleotide reverse transcriptase inhibitors (NNRTI) and nucleotide reverse transcriptase inhibitors (NRTI) drugs were 11.4% and 10.1%, respectively. Mutations responsible for NRTI resistance were M184V (30.1%), K65R (12.1%), and D67N (5.6%). Moreover, NNRTI-associated mutations were K103N (14.8%), Y181C (11.8%), and G190A (7.7%). Children who had a history of opportunistic infection [AHR (95% CI) = 3.4 (1.8-6.2)], vitamin D < 20 ng/mL [AHR (95% CI) = 4.5 (2.1-9.9)], drug resistance [AHR (95% CI) = 2.2 (1.4-3.6)], and VF [AHR (95% CI) = 2.82 (1.21, 3.53)] had a higher hazard of disease progression; whereas, being orphan [AOR (95% CI) = 1.8 (1.2-3.1)], history of drug substitution [(AOR (95% CI) = 4.8 (2.1-6.5), hemoglobin < 12 mg/dL [AOR (95% CI) = 1.2 (1.1-2.1)] had higher odds of developing drug resistance. Conclusions: Immunosuppression was increasing over time and drug resistance was also substantially high. Enhancing routine monitoring of viral load and HIVDR and providing a vitamin-D supplement during clinical management could help improve the immunologic outcome. Limiting HAART substitution is also crucial for children taking HAART in Ethiopia.

IntroductionAdverse drug reactions are a major global public health concern and an important cause of hospitalization, discontinuation of the drug, morbidity and mortality. Even though the prevalence in Ethiopia was declining at a moderate rate, still, far too many people are suffering and dying unnecessarily due to adverse drug reactions.ObjectiveThe aim of this study was to determine the incidence of adverse drug reaction and its predictors among adult patients on antiretroviral therapy.MethodsA retrospective follow-up study was conducted at Nigist Elleni Mohamed Memorial Comprehensive Specialized Hospital, Southern Ethiopia. Data were extracted from patients’ medical records. The Weibull model with gamma frailty distribution was fitted. Statistical significance was employed at a 5% level of significance and adjusted hazard ratio with 95% confidence interval was used.ResultsOut of the total 376 participants followed for 1988 person years of observations, 96 developed adverse reaction with the incidence rate of 4.820/100 per (95%CI: 4.102–5.317). The univariate frailty was statistically significant (theta=0.306, 95%CI: 0.102–0.521). Baseline CD4 count (AHR: 0.997, 95%CI: 0996–0.998), fair adherence (AHR: 2.358, 95%CI: 1.133–4.904), poor adherence (AHR: 3.069, 95%CI: 1.730–5.445), HIV/TB coinfection (AHR: 2.069, 95%CI: 1.115–3.843), WHO stage II (3.128, 95%CI: 1.414–6.916), WHO stage III (AHR: 2.709, 95%CI: 1.048–7.025) and WHO stage IV (1.516, 10.352) were associated with the incidence adverse reaction.ConclusionMost of the ADR cases occurred within two years after initiation of ART. Advanced clinical stage, TB coinfection, CD4 count, and poor adherence were predictors of ADRs. Continuous counseling for clients in advanced clinical stage and patients with TB coinfection need to get close follow-up to prevent the associated ADRs by the concerned parties.

Introduction: Diabetes mellitus (DM) is an important chronic comorbid condition that occurs in people living with the human immunodeficiency virus (HIV). It is associated with increased morbidity and mortality. Many cases of comorbidities with diabetes mellitus have been reported, particularly in areas of the world where the prevalence of HIV is high. The rate of diabetes hospitalizations among HIV-infected individuals increased from 3.9 to 8.4 per 100 hospitalizations. Although the cost of HIV care has increased, the burden of DM among people living with HIV has economic consequences. Objectives: This study aimed to assess the incidence of DM among HIV patients receiving ART in the Asella Referral and Teaching Hospital, Oromia Regional State, Ethiopia. Methods: Ten years retrospective follow-up study was conducted among 268 HIV patients receiving ART at Asella Referral and Teaching Hospital. HIV patients receiving ART between January 01/2013 and Dec 31/2022 were enrolled in this study. A systematic sampling technique was used to select patients’ medical charts. Data were extracted from the patients’ medical chart records from March 21 to March 23, 2023, using a data extraction format. Data were entered into Epi Data version 4.6.0.0, and exported to STATA version 14.2 for statistical analysis. Results: A total of 268 medical charts of HIV patients receiving ART were included in the final analysis, which provided a response rate of 98.52%. The mean age of participants was 38.17 years. Among 268 HIV patients followed for 10 years, 142 (52.99%) were female, 33(49.63%) were aged between 30-40 years. Approximately 154 (57.46%) of them were urban residents. The incidence density rate (IDR) of DM in the cohort of HIV patients receiving ART during 1291.33 person-year observation was 6.20 per 1000 [95% CI: 3.10, 12.39] person-years. The cumulative incidence proportion of DM among HIV patients receiving ART was 2.99% [95% CI: 1.49, 5.88] within the 10 years follow-up period. Conclusion: The incidence of DM among HIV patients receiving ART was relatively high. It is important to emphasize HIV patients receiving ART for early screening of DM among these patients.

BackgroundThere is very little data on long-term immune recovery responses in patients on suppressive antiretroviral therapy (ART) in the setting of sub-Saharan Africa (SSA). Thus, we sought to determine CD4+ T-cell, CD8+ T-cell and CD4/CD8 ratio responses in a cohort of HIV infected individuals on sustained suppressive ART followed up for more than a decade.MethodsThe cohort comprised adult patients who started ART between 2001 and 2007 and followed for up to 14 years. Trends in median CD4+ T-cells, CD8+ T-cells and CD4/CD8 ratio were reviewed retrospectively. Poisson regression models were used to identify factors associated with achieving normalized T-cell biomarkers. Kaplan-Meier curves were used to estimate the probability of attaining normalized counts while on suppressive ART.ResultsA total of 227 patients with a median duration of follow-up on ART of 12 (IQR: 10.5–13.0) years were included. CD4 cell count increased from baseline median of 138 cells (IQR: 70–202) to 555 cells (IQR: 417–830). CD4 cell increased continuously up until 5 years, after which it plateaued up until 14 years of follow up. Only 69.6% normalized their CD4 cell count within a median of 6.5 (IQR: 3.0–10.5) years. In addition, only 15.9% of the cohort were able to achieve the median reference CD4+ T-cell threshold count in Ethiopians (≈760 cells/μL). CD8+ T-cell counts increased initially until year 1, after which continuous decrease was ascertained. CD4/CD8 ratio trend revealed continuous increase throughout the course of ART, and increased from a median baseline of 0.14 (IQR: 0.09–0.22) to a median of 0.70 (IQR: 0.42–0.95). However, only 12.3% normalized their ratio (≥ 1.0) after a median of 11.5 years. In addition, only 8.8% of the cohort were able to achieve the median reference ratio of healthy Ethiopians.ConclusionDetermination of both CD4+ and CD8+ T-cells, along with CD4/CD8 ratio is highly relevant in long-term follow-up of patients to assess immune recovery. Monitoring ratio levels may serve as a better biomarker risk for disease progression among patients on long-term ART. In addition, the findings emphasize the relevance of initiation of ART at the early stage of HIV-1 infection.
