Abstract
OBJECTIVE HIV/AIDS mortality remains significantly high in sub-Saharan Africa, mostly driven by opportunistic infections and advanced HIV disease (AHD). This study aimed to assess CD4 + cell count recovery following ART initiation and factors associated with immune reconstitution. METHODS We conducted a prospective cohort study between 2015 and 2016. HIV-infected adults (≥18 years) with AHD (CD4 + cell count ≤100 cells/μl) receiving care at 20 outpatient HIV treatment facilities in Harare, Zimbabwe were enrolled. CD4 + cell count recovery (CD4 + cell count >200 cells/μl) was assessed following 12-month ART initiation and factors associated with immune reconstitution were investigated using logistic regression analysis. All statistical analyses were performed on Statistical Package for the Social Sciences (SPSS) version 23. RESULTS 1320 participants were enrolled and 56.4% were males. The median (interquartile range, IQR) age was 37 (32-43) years. Tuberculosis was seen in 16.0%. Of the 739 participants that had CD4 + cell count at 12 months, CD4 + cell count recovery above 200 cells/μl was observed in 163 (22.1%) participants. Median (IQR) CD4 + cell count at 12-months increased to 127 (75-190) cells/μl from 31 (14-55) at baseline. Factors associated with CD4 + cell count recovery were younger age at baseline [odds ratio (OR) ≥40/<40 = 0.58, 95% confidence interval (CI): 0.40-0.85, P = 0.005), sex (OR female/male = 2.07, 95% CI: 1.44-2.99, P < 0.0001) and baseline CD4 + cell count (OR ≥50/<50 = 1.60, 95% CI: 1.10-2.33, P = 0.013). CONCLUSION A significant proportion (77.9%) of patients seeking care with AHD in a resource limited setting failed to recover a CD4 + cell count >200 cells/μl. Male sex, older age and low CD4 + cell count at ART initiation were factors associated with poor immune reconstitution. Better differentiated care deliveries targeting this vulnerable population are critical for improving clinical outcomes and quality of life of the patients.

Abstract
Background Globally, approximately 35 million people are infected with HIV infection. Sub-Saharan countries contributed 71% of global burden. Women are the most affected groups accounting for 51% of global infection and 90% of HIV infections in children (<15 years) are a result of mother to child transmission. In the absence of any intervention, mother-to-child transmission has been estimated to 30-40% that could occur at various periods like during pregnancy, delivery, and post-partum, via breastfeeding. For future generations to be born HIV-free, evidences on the level of viremia and contributing factors in pregnant mothers is important. Objective The objective of this study is to determine the magnitude of viral non-suppression rate among pregnant women and identify the risk factors associated with viral non-suppression. Methods A cross-sectional study was conducted from July 01, 2021 to June 30, 2022, in pregnant women who are on antiretroviral treatment and attending HIV viral load testing in Amhara region viral load testing sites, North West Ethiopia. Socio-demographic, clinical, and HIV-1 RNA viral load data were collected from the excel database. The data were analyzed in SPSS 23.0 statistical software. Results Overall viral non-suppression rate was 9.1%. In other words, the viral suppression rate was 90.9%. Pregnant women being at AIDS stages III and IV and with fair treatment adherence and suspected testers were statistically associated with increased viral non-suppression rate. Conclusion Relatively low viral non-suppression rate among pregnant mothers that had almost met the third 90 of UNAIDS target. But, still, some mothers received a non-suppressed viral replication specifically the odds of having a non-suppressed viral load was higher in pregnant women with poor treatment adherence and WHO Stage III and IV and suspected testers.

Abstract
Background CD4+ cell count recovery after effective antiretroviral therapy (ART) is an important determinant of both AIDS and non-AIDS morbidity and mortality. Data on CD4+ cell count recovery after initiation of ART are still limited in Sub-Saharan Africa. The aim of this study was to assess CD4+ cell count recovery among HIV-infected adults initiating ART in an Ethiopian setting. Methods A retrospective cohort study of HIV-infected adults initiating ART between September 2008 and June 2019 was carried out. CD4+ cell count recovery was defined as an increase in CD4+ cell count of >100 cells/mm3 from baseline or achievement of a CD4+ cell count >500 cells/mm3 at 12 months after ART initiation. Factors associated with CD4+ cell count recovery were evaluated using logistic regression analysis. Results Of the 566 patients included in this study, the median baseline CD4+ cell count was 264 cells/mm3 (IQR: 192–500). At 12 months after ART initiation, the median CD4+ cell count increased to 472 cells/mm3, and the proportion of patients with CD4+ cell count < 200 cells/mm3 declined from 28.3 to 15.0%. A total of 58.0% of patients had an increase in CD4+ cell count of >100 cells/mm3 from baseline and 48.6% achieved a CD4+ cell count >500 cells/mm3 at 12 months. Among patients with CD4+ cell counts < 200, 200–350 and >350 cells/mm3 at baseline, respectively, 30%, 43.9% and 61.7% achieved a CD4+ cell count >500 cells/mm3 at 12 months. In multivariable analysis, poor CD4+ cell count recovery (an increase of ≤100 cells/mm3 from baseline) was associated with older age, male sex, higher baseline CD4+ cell count and zidovudine-containing initial regimen. Factors associated with poor CD4+ cell count recovery to reach the level >500 cells/mm3 included older age, male sex and lower baseline CD4+ cell count. Conclusions CD4+ cell count failed to recover in a substantial proportion of adults initiating ART in this resource-limited setting. Older age, male sex and baseline CD4+ cell count are the dominant factors for poor CD4+ cell count recovery. Novel therapeutic approaches are needed focusing on high risk patients to maximize CD4+ cell count recovery and improve outcomes during therapy.

Abstract
Purpose This study was conducted to investigate the drug resistance mutations and genetic diversity of HIV-1 in ART experienced patients in South Omo, Ethiopia. Patients and Methods A cross-sectional study conducted on 253 adult patients attending ART clinics for ≥6 months in South Omo. Samples with VL ≥1000 copies/mL were considered as virological failures (VF) and their reverse transcriptase gene codons 90–234 were sequenced using Illumina MiSeq. MinVar was used for the identification of the subtypes and drug resistance mutations. Phylogenetic tree was constructed by neighbor-joining method using the maximum likelihood model. Results The median duration of ART was 51 months and 18.6% (47/253) of the patients exhibited VF. Of 47 viraemic patients, the genome of 41 were sequenced and subtype C was dominant (87.8%) followed by recombinant subtype BC (4.9%), M-09-CPX (4.9) and BF1 (2.4%). Of 41 genotyped subjects, 85.4% (35/41) had at least one ADR mutation. Eighty-one percent (33/41) of viraemic patients harbored NRTI resistance mutations, and 48.8% (20/41) were positive for NNRTI resistance mutations, with 43.9% dual resistance mutations. Among NRTI resistance mutations, M184V (73.2%), K219Q (63.4%) and T215 (56.1%) complex were the most mutated positions, while the most common NNRTI resistance mutations were K103N (24.4%), K101E, P225H and V108I 7.5% each. Active tuberculosis (aOR=13, 95% CI= 3.46–29.69), immunological failure (aOR=3.61, 95% CI=1.26–10.39), opportunistic infections (aOR=8.39, 95% CI= 1.75–40.19), and poor adherence were significantly associated with virological failure, while rural residence (aOR 2.37; 95% CI: 1.62–9.10, P= 0.05), immunological failures (aOR 2.37; 95% CI: 1.62–9.10, P= 0.05) and high viral load (aOR 16; 95% CI: 5.35 51.59, P <0.001) were predictors of ADR mutation among the ART experienced and viraemic study subjects. Conclusion The study revealed considerable prevalence of VF and ADR mutation with the associated risk indicators. Regular virological monitoring and drug resistance genotyping methods should be implemented for better ART treatment outcomes of the nation.

Long-Term Immunological and Virological Outcomes in Children Receiving Highly Active Antiretroviral Therapy at Hawassa University College of Medicine and Health Sciences, Southern Ethiopia. J Immunol Res 2021; 2021:2498025. [PMID: 33928167 PMCID: PMC8053046 DOI: 10.1155/2021/2498025] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Revised: 02/14/2021] [Accepted: 03/10/2021] [Indexed: 11/22/2022] Open
Abstract
Purpose To determine immunological and virological failure and associated factors among children infected with human immunodeficiency virus receiving antiretroviral treatments at Hawassa University Hospital, Southern Ethiopia. Methods A hospital-based cross-sectional study was conducted among 273 HIV-infected children from July 1 to December 1, 2019. Data were collected using a structured questionnaire and review of patient records. Blood samples for viral load and CD4 count were collected. Data were analyzed using SPSS version 20. Significance group comparison was done by the Kaplan-Meier log-rank test. The Cox proportional hazard model was used to select significant factors of the variability between groups. Results A total of 273 children, between the age ranges of 1 to 14 years, were included. Of these, 139 (50.9%) and 134 (49.1%) were males and females, respectively. Children from the rural area were almost five times more vulnerable for virological and immunological failure than those children from the urban area (AOR = 4.912, (1.276-8.815), P = 0.032). The overall viral load suppression was 196 (71.8%) with a good adherence of 226 (82.9%). Nonsuppressed HIV viral load was found to be 77 (28.2%) which had two times more viral load copies (AOR = 2.01, (1.21–2.66), P = 0.001) when compared to those who had suppressed viral load copies. The proportions of children who had immunological nonresponse were 45.6% (21 out of 46), 30.4% (14 out of 46), and 23.9% (11 out of 46) among children with baseline CD4 of <200, 201-500, and >500 cells/μl, respectively. Unimproved outcomes among females were noted for immunological and virological failure in this study (AOR = 1.901, (1.038-3.481), P = 0.038). Conclusion In conclusion, the highly active antiretroviral treatment appeared highly effective in terms of immunological and virological long-term outcomes. However, viral suppression (71.8%) in our study was far apart from the UNAIDS target of 90% in 2020. For that reason, strengthening adherence counseling and early initiation of HAART is important.

Abstract
OBJECTIVE This study aimed to identify determinants of immunological recovery following highly active antiretroviral therapy (HAART) among severely immunosuppressed patients at enrolment to care in Northern Ethiopia. METHODS A retrospective study. SETTING The study was done in Tigray Region, Northern Ethiopia. PARTICIPANTS The study was done among severely immunosuppressed (<200 CD4 cells/mm3) individuals at initial enrolment to care and whose samples were sent for viral load determination from April 2015 to March 2019 in Tigray Health Research Institute. MAIN OUTCOMES The main outcome variable was immunological recovery, modelled using binary logistic regression. RESULTS Among the 9687 patients with severe immunosuppression at enrolment, 2746 (28.35%, 95% CI 27.45% to 29.26%) had immunological recovery following HAART for at least 6 months. Male gender (adjusted OR (AOR)=0.50, p<0.001), age 20-34 years old (AOR=0.33, p<0.001), age ≥50 years old (AOR=0.26, p<0.001), WHO clinical stage III (OR=0.68, p=0.036) and viral non-suppression (AOR=0.38, p<0.001) were strong predictors of immunological failure. CONCLUSIONS Immunological recovery following HAART was low among severely immunosuppressed individuals at enrolment to care. Gender, age, WHO stage III and viral non-suppression were determinants of immunological recovery. Male patients, adolescents and virally non-suppressed patients should be identified as groups at higher risk for immunological failure. Therefore, greater support and intensive counselling should be prioritised among adolescents, men and virally non-suppressed patients for better immunological recovery.

Abstract
PURPOSE After the initiation of highly active antiretroviral therapy (HAART), successful HAART is characterized by an increase in the CD4+ count. Several factors affect the CD4+ T-cell count. This study aimed to assess the immunological response during HAART and determinants of the current CD4+ T-cell count among HIV/AIDS patients on HAART. PATIENTS AND METHODS A hospital-based cross-sectional study was conducted from February 1 to April 1, 2017. A total of 423 HIV/AIDS patients on HAART were enrolled using simple random sampling. Descriptive statistics, and bivariate and multiple regression analyses were conducted. Variables with p-value <0.2 in the bivariate analysis were entered in the multiple regression models. p-Values <0.05 and 95% confidence intervals were used to identify determinants of the current CD4+ T-cell count. RESULTS The mean CD4+ T-cell count gradually increased until 8 years on HAART but declined thereafter. An increased current CD4+ T-cell count was observed among patients with an initial regimen of pediatric d4T-3TC-NVP [β=185.5, 95% CI (8.8, 362.2)] (p=0.040), with increased baseline CD4+ T-cell count [β=0.468, 95% CI (0.342, 0.594)] (p<0.0001), and with long duration on HAART [β=18.0, 95% CI (9.9, 26.1)] (p<0.0001), whereas a decreased level of current CD4+ T-cell count was observed among males [β=-72.7, 95% CI (-114.5, -30.9)]) (p<0.0001) and those with poor baseline adherence [β=-108.9, 95% CI (-210.9, -7.0)] (p=0.036) and viral load >1000 copies [β=-189.2, 95% CI (-243.5, -134.9)] (p<0.0001). CONCLUSION The trend in immunological response was not increased linearly throughout the HAART duration. Sex, type of initial regimen, baseline adherence, baseline CD4+ count, viral load, and duration on HAART were independent determinants of current CD4+ count. These determinants could be addressed by regular monitoring of HIV patients on HAART, and special attention should be paid to male patients.

Abstract
The study reports the response of first-line antiretroviral therapy (ART) by assessing
CD4 and CD8 T-lymphocyte and viral load (VL) among Bangladeshi people living with HIV
(PLHIV). This observational approach was conducted on 100 PLHIVs, grouped into therapy
naive (n = 33), therapy initiators with CD4 T-cell count of <350 cells/µL (n = 33), and
therapy receivers for >1 year prior to the study period (n = 34). Therapy initiators
who continued the study (n = 20) were followed up after 12 and 24 weeks of therapy
initiation. The CD4 and CD8 T-lymphocyte count estimation and (VL) were quantified. The
mean CD4 T-lymphocyte count was significantly reduced among the therapy initiators in
comparison to therapy naive and therapy receivers. Similar findings were observed for CD8
T-lymphocyte count among the study groups. The mean HIV-1 RNA VL among therapy initiators
showed a significant decrease after 12 and 24 weeks, and 85% patients in this group
obtained undetectable VL status indicating the good therapeutic outcome.

Abstract
Background:
Pediatric antiretroviral treatment failure is an under-recognized issue that receives inadequate attention in the field of pediatrics and within HIV treatment programs. Despite the reduction in morbidity and mortality, a considerable proportion of patients fail to achieve a sustained virologic response to therapy. Thus virological failure is an increasing concern globally.
Objective:
This study aimed to assess the virological failure and associated risk factors among HIV/AIDS pediatric patients at Antiretroviral Treatment (ART) follow up clinic of Jimma University Medical Center, southwest Ethiopia.
Methods:
An institution based cross-sectional study was conducted at the ART follow-up clinic of Jimma University Medical Center. A structured English version checklist was developed and used for data extraction from patients’ charts from April -May 2019. Then the data was coded and entered using epi data 4.2 and exported to statistical package for social science (SPSS version 22) for analysis. Descriptive analysis was conducted for categorical as well as continuous variables. Multivariable logistic regression was performed in a backward, step-wise manner until a best-fit model was found.
Results:
Of 140 HIV/AIDS pediatric patients enrolled in this study, 72(51.4%) were male and the mean age was 9.7±3.3 Years. ABC-3TC-NVP was the commonly used ART medication in this population, which was 37.1% followed by AZT-3TC-EFV(32.1%). The mean duration of antiretroviral treatment (ART) follow-up was 63.8±29.4 months. Among the study population, 11.0% of them had virological failure. Weight at ART initiation [OR=1.104, 95 CI% [1.013-1.203], p=0.024] and WHO clinical stage 3 [AOR=0.325, 95CI, 0.107-0.991,P=0.048] were the significant risk factors for the virological failure.
Conclusion:
A significant proportion of HIV/AIDS pediatric patients had virological failure. Weight at ART initiation and patients having WHO clinical stage 3 were risk factors associated with virological failure in this study. Governmental and non-governmental concerned bodies should invest their effort to devise strategies for the achievement of HIV/AIDS treatment targets.

Abstract
Background Antiretroviral therapy has resulted in significant reductions in HIV-associated complications by recovering the CD4+ T cell count. Some patients may not be successful in attaining this result, and some may achieve it only after many years of treatment. Objective This study aimed to assess CD4+ T cell recovery and non-response patterns among HAART experienced HIV-positive patients at the Arsi Negelle health center. Methods This was a retrospective cross-sectional study conducted among HAART experienced HIV/AIDS patients at Arsi Negelle Health Center from January 01, 2014 to January 06, 2019. Data were documented to a data retrieval form and analyzed with SPSS version 20. Linear regression analysis was used to identify predictors of CD4 count change. A P-value of <0.05 was considered significant. Results The total median of CD4+ T cells increased from 257 cells/uL at the baseline to 382 cells/uL after 6 months, then to 591 cells/uL after 60 months of treatment. The non-response rate was 22.1% and 23.8% among the total study participants and children of less than 15 years, respectively. Only baseline CD4+ T cell was associated with a change in CD4+ T cell count. Conclusion From our study, we can conclude that CD4+ T cell count has recovered in most of the study participants after HAART initiation. The immunological non-response rate of study participants was 22.1% after 12 months on HAART and 7.2% at the end of the study.

HIV virological non-suppression and factors associated with non-suppression among adolescents and adults on antiretroviral therapy in northern Ethiopia: a retrospective study. BMC Infect Dis 2020; 20:4. [PMID: 31898535 PMCID: PMC6941313 DOI: 10.1186/s12879-019-4732-6] [Citation(s) in RCA: 46] [Impact Index Per Article: 11.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2019] [Accepted: 12/24/2019] [Indexed: 01/19/2023] Open
Abstract
Background Despite the benefits of Antiretroviral Therapy (ART), there is a growing concern of treatment failure. This study aimed to assess viral non suppression rate and factors associated with HIV viral non suppression among adolescents and adults on ART in Northern Ethiopia. Methods A retrospective cross sectional study was done on 19,525 study subjects. All the data in the database of Tigray Health Research Institute was exported to Microsoft excel 2010 and then data verification and filtration were done before exporting to STATA 14.0 for analysis. Generalized Estimating Equation (GEE) logistic regression was used for statistical modeling of viral non suppression. Results A total of 5153 (26.39%; 95%CI (25.77%, 27.02)) patients had no viral suppression despite being on ART. Being male (AOR = 1.27, 95% CI: 1.18, 1.37), 15–19 years of age (AOR = 4.86, 95%CI: 3.86, 6.12), patients from primary hospital (AOR = 1.26, 95%CI: 1.05, 1.52), WHO staging II (AOR = 1.31, 95%CI: 1.10, 1.54), poor ART adherence level (AOR = 2.56, 95%CI: 1.97, 3.33), fair ART adherence level (AOR = 1.61, 95%CI: 1.36, 1.90), baseline CD-4 count of < 200 cells/micro liter (AOR = 1.33, 95%CI: 1.14, 1.54), recent CD-4 count of < 200 cells/micro liter (AOR = 3.78, 95%CI: 3.34, 4.27), regimen types: 1c (AZT-3TC-NVP) (AOR = 1.32, 95%CI: 1.22, 1.44), 2 h (TDF-3TC-ATV/R) (AOR = 1.79, 95%CI: 1.27, 2.52) and declined immunological responses after ART initiation (AOR = 1.45, 95%CI: 1.30, 1.61) were significantly associated with viral non-suppression. Conclusions The virological non suppression was high which makes it less likely to achieve the third 90 UNAIDS target. Being male, patients with WHO staging II and poor ART adherence level were significantly associated with viral non suppression. Therefore, intensive adherence support and counseling should be provided. It is also a high time to determine the antiretroviral drugs resistance pattern given the fact that a large number of patients had virological non suppression.

Abstract
Background This study was aimed to assess immunological recovery, failure, and factors associated with CD-4 T-cells progression over time, among adolescents and adults living with HIV on Antiretroviral Therapy in Northern Ethiopia. Methods A retrospective cross sectional study was done on 19,525 HIV patients on ART. Data were collected using a data retrieval checklist from a database. All eligible data in the database were exported to Microsoft excel 2010 and then data verification and filtration were done before exporting to STATA 14.0 for analysis. Factors associated with recent CD-4 count were modeled by using Generalized Linear Model poison family. Results Among the patients with advanced HIV infection (< 200 CD-4 T-cell/ mm3) at baseline, only 28.35%, 95% CI (27.45–29.26) of them had immunological recovery (≥ 500 T-cells/mm3). Only 2.14%, 95%CI (1.94%- 2.35%) of the patients had immunological failure. Baseline CD-4 count (Incidence Rate Ratio (IRR) = 1.0007, 95%CI = 1.00069–1.00078), patients from military health care facility (IRR = 1.11, 95%CI = 1.06–1.16), good adherence (IRR = 1.12, 95%CI = 1.04–1.21) and viral load suppression (IRR = 1.31, 95%CI = 1.28–1.33) were positively associated with recent CD-4 count in the full model. Whereas, being male (IRR = 0.85, 95%CI = 0.83–0.86), patients with on Anti-Retroviral Therapy (ART) regimen of 1e (TDF-3TC-EFV), 2f (AZT-3TC-ATV/r), and 2h (TDF-3TC-ATV/r) (IRR = 0.92, 95%CI = 0.91–0.94), (IRR = 0.65, 95%CI = 0.55–0.76) and (IRR = 0.71, 95%CI = 0.63–0.81) respectively were negatively associated with the recent CD-4 count in the full model. Conclusions Immunological recovery was achieved by 1/3 of the patients despite being on highly active ART (HAART). Therefore, intensive adherence counseling, follow-up and support should be focused on patients with viral non suppression to enhance immunological recovery.

Abstract
There is limited data on virologic outcome and its correlates among HIV-infected children in resource-limited settings. We investigated rate and correlates of virologic outcome among treatment naïve HIV-infected Ethiopian children initiating cART, and were followed prospectively at baseline, 8, 12, 24 and 48 weeks using plasma viral load, clinical examination, laboratory tests and pretreatment HIV drug resistance (PDR) screening. Virologic outcome was assessed using two endpoints–virological suppression defined as having “undetectable” plasma viral load < 150 RNA copies/mL, and rebound defined as viral load ≥150 copies/mL after achieving suppression. Cox Proportional Hazards Regression was employed to assess correlates of outcome. At the end of follow up, virologic outcome was measured for 110 participants. Overall, 94(85.5%) achieved virological suppression, of which 36(38.3%) experienced virologic rebound. At 48 weeks, 9(8.2%) children developed WHO-defined virological treatment failure. Taking tenofovir-containing regimen (Hazard Ratio (HR) 3.1-[95% confidence interval (95%CI) 1.0–9.6], p = 0.049) and absence of pretreatment HIV drug resistance (HR 11.7-[95%CI 1.3–104.2], p = 0.028) were independently associated with earlier virologic suppression. In conclusion, PDR and cART regimen type correlate with rate of virologic suppression which was prominent during the first year of cART initiation. However, the impact of viral rebound in 38.3% of the children needs evaluation.

Adherence to antiretroviral treatment among children and adolescents in Tanzania: Comparison between pill count and viral load outcomes in a rural context of Mwanza region. PLoS One 2019; 14:e0214014. [PMID: 30897131 PMCID: PMC6428300 DOI: 10.1371/journal.pone.0214014] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2018] [Accepted: 03/05/2019] [Indexed: 01/06/2023] Open
Abstract
BACKGROUND AND OBJECTIVES Adherence to antiretroviral treatment is a key challenge for paediatric HIV care. Among children and adolescents living with HIV, lower levels of adherence have been reported compared to adults. Individual, caregiver-, health services-related and sociocultural factors were shown to impact on these outcomes. Study objectives were to assess adherence in a paediatric population in rural Tanzania comparing two measurement methods, and to investigate the association between virologic suppression and demographic, clinical, drug- and family-related factors. METHODS This cross-sectional study was conducted among children and adolescents enrolled in Bukumbi HIV Care and Treatment Clinic (Misungwi district, Mwanza region) in the north of Tanzania, where the HIV prevalence is 7.2%. Adherence was measured through viral load and pill count. Kappa statistics assessed the level of agreement between the methods; bivariate and multivariable analyses identified factors independently associated with virologic suppression. RESULTS N = 72 participants (n = 49 children; n = 23 adolescents) with a median age of eight years were enrolled. 62.5% and 65.3% of the individuals presented an optimal adherence according to viral load and pill count respectively, but among 40% viral load results diverged from the pill count method. In multivariable analysis, living outside Misungwi district and having CD4 counts above 500/μl were significantly associated with optimal adherence. CONCLUSION Children and adolescents living with HIV in Mwanza show high rates of suboptimal adherence. The poor agreement between pill count and viral load results raises concerns about the interpretation of these measurements in clinical practice.

Abstract
OBJECTIVE To investigate the incidence and predictors of viraemia among individuals on antiretroviral therapy (ART) in Harare, Zimbabwe. METHODS Children (0-19 years) and adults (>19 years) starting ART between 2013 and 2015 were followed for a median of 2.8 and 2.7 years, respectively. The incidence rates of virological failure (VF), low-level viraemia (LLV), and viral blips were assessed and the predictors of viraemia were determined using logistic and parametric survival regression analyses. RESULTS A total of 630 individuals initiated ART, and 19.7% of children and 5.6% of adults did not achieve viral suppression by 12 months. Younger age and CD4 count ≤200 cells/mm3 at baseline were associated with not being virally suppressed at 12 months in adults. Among those who achieved viral suppression during the follow-up period, the incidence of VF was higher in children (4.0/100 person-years vs. 0.4/100 person-years in adults; p<0.001), as was the incidence of LLV (1.9/100 person-years vs. 0.3/100 person-years in adults; p=0.03). The incidence rate of blips was 10.9 per 100 person-years in children and 4.0 per 100 person-years in adults. CONCLUSIONS Children are less likely to reach viral suppression and are at higher risk of viraemia while on ART than adults. The significance of LLV and blips needs further study.

Abstract
Clinical monitoring of pediatric HIV treatment remains a major challenge in settings where drug resistance genotyping is not routinely available. As a result, our understanding of drug resistance, and its impact on subsequent therapeutic regimens available in these settings, remains limited. We investigate the prevalence and correlates of HIV-1 drug resistance among 94 participants of the Ethiopia Pediatric HIV Cohort failing first-line combination antiretroviral therapy (cART) using dried blood spot-based genotyping. Overall, 81% (73/90) of successfully genotyped participants harbored resistance mutations, including 69% (62/90) who harbored resistance to both Nucleoside Reverse Transcriptase Inhibitors (NRTIs) and Non-nucleoside Reverse Transcriptase Inhibitors (NNRTIs). Strikingly, 42% of resistant participants harbored resistance to all four NRTIs recommended for second-line use in this setting, meaning that there are effectively no remaining cART options for these children. Longer cART duration and prior regimen changes were significantly associated with detection of drug resistance mutations. Replicate genotyping increased the breadth of drug resistance detected in 34% of cases, and thus is recommended for consideration when typing from blood spots. Implementation of timely drug resistance testing and access to newer antiretrovirals and drug classes are urgently needed to guide clinical decision-making and improve outcomes for HIV-infected children on first-line cART in Ethiopia.

Abstract
Objectives Kenya is one of the first African countries to scale up a national HIV viral load monitoring program. We sought to assess program scale up using the national database and identify areas for systems strengthening. Methods Data from January 2012 to March 2016 were extracted from Kenya’s national viral load database. Characteristics of 1,108,356 tests were assessed over time, including reason for testing, turnaround times, test results, treatment regimens, and socio-demographic information. Results The number of facilities offering viral load testing increased to ~2,000 with >40,000 tests being conducted per month by 2016. By March 2016, most (84.2%) tests were conducted for routine monitoring purposes and the turnaround time from facility-level sample collection to result dispatch from the lab was 21(24) [median (IQR)] days. Although the proportions of repeat viral load tests increased over time, the volumes were lower than expected. Elevated viral load was much more common in pediatric and adolescent patients (0-<3 years: 43.1%, 3-<10 years: 34.5%, 10-<20 years: 36.6%) than in adults (30-<60 years: 13.3%; p<0.001). Conclusions Coverage of viral load testing dramatically increased in Kenya to >50% of patients on antiretroviral therapy (ART) by early 2016 and represents a relatively efficient laboratory system. However, strengthening of patient tracking mechanisms and viral load result utilization may be necessary to further improve the system. Additional focus is needed on paediatric/adolescent patients to improve viral suppression in these groups. Kenya’s national viral load database has demonstrated its usefulness in assessing laboratory programs, tracking trends in patient characteristics, monitoring scale-up of new policies and programs, and identifying problem areas for further investigation.

[PMID: 29095936 PMCID: PMC5667926 DOI: 10.1371/journal.pone.0187694] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2016] [Accepted: 10/24/2017] [Indexed: 02/03/2023] Open
Abstract
BACKGROUND 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. METHODS 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. RESULTS 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. CONCLUSIONS 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.

Abstract
PURPOSE There have been hardly any reports on the human immunodeficiency virus type 1 (HIV-1) drug-resistance profile from northern Ghana since antiretroviral therapy (ART) was introduced over a decade ago. This study investigated prevailing HIV-1 subtypes and examined the occurrence of drug resistance in ART-experienced patients in Tamale, the capital of the Northern Region of Ghana. METHODOLOGY A cross-sectional study was carried out on HIV-infected adult patients receiving first-line ART. HIV viral load (VL) and CD4+ T-cell counts were measured. The pol gene sequences were analysed for genotypic resistance by an in-house HIV-1 drug-resistance test; the prevailing HIV-1 subtypes were analysed in detail.Results/Key findings. A total of 33 subjects were studied. Participants comprised 11 males (33.3 %) and 22 (66.7 %) females, with a median age of 34.5 years [interquartile range (IQR) 30.0-40.3]. The median duration on ART was 12 months (IQR 8.0-24). Of the 24 subjects successfully genotyped, 10 (41.7 %) viruses possessed at least one mutation conferring resistance to nucleoside or non-nucleoside reverse-transcriptase inhibitors (NRTIs/NNRTIs). Two-class drug resistance to NRTI and NNRTI was mostly detected (25 %, 6/24). The most frequent mutations were lamivudine-resistance M184V and efavirenz/nevirapine-resistance K103N. HIV-1 subtype CRF02_AG was predominant (79.2 %). Other HIV-1 subtypes detected were G (8.3 %), A3 (4.2 %) and importantly two (8.3 %) unique HIV-1 recombinant forms with CRF02_AG/A3 mosaic. CONCLUSION HIV-1 shows high genetic diversity and on-going viral genetic recombination in the study region. Nearly 42 % of the patients studied harboured a drug-resistant virus. The study underscores the need for continued surveillance of HIV-1 subtype diversity; and of drug-resistance patterns to guide selection of second-line regimens in northern Ghana.

Abstract
Background The emergence, accumulation and spread of HIV-1 drug resistance strains in Africa could compromise the effectiveness of HIV treatment programs. This study was aimed at determining the incidence of virological failure and acquired drug resistance mutations overtime and identifying the most common mutational pathways of resistance in a well characterized HIV-1C infected Ethiopian cohort. Methods A total of 320 patients (220 ART naïve and 100 on first lines ART) were included and followed. ART initiation and patients’ monitoring was based on the WHO clinical and immunological parameters. HIV viral load measurement and genotypic drug resistance testing were done at baseline (T0-2008) and after on average at a median time of 30 months on ART at three time points (T1-2011, T2-2013, T3-2015). Findings The incidence of virological failure has increased overtime from 11 at T1 to 17 at T2 and then to 30% at T3. At all time point’s almost all of the patients with virological failure and accumulated drug resistance mutations had not met the WHO clinical and immunologic failure criteria and continued the failing regimen. A steep increase in the incidence and accumulation of major acquired NRTI and NNRTI drug resistance mutations have been observed (from 40% at T1 to 64% at T2 and then to 66% at T3). The most frequent NRTIs drug resistance associated mutations are mainly the lamivudine-induced mutation M184V which was detected in 4 patients at T1 and showed a 2 fold increase in the following time points (T2: n = 8) and at (T3: n = 12) and the thymidine analogue mutations (such as D67N, K70R and K219E) which were not-detected at baseline T0 and T1 but were increased progressively to 10 at T2 and to 17 at T3. The most frequent NNRTIs associated mutations were K103N, V106M and Y188C. Conclusions An upward trend in the incidence of virological failure and accumulation of NRTI and NNRTI associated acquired antiretroviral drug resistance mutations are observed. The data suggest the need for virological monitoring, resistance testing for early detection of failure and access for TDF and PI containing drugs. Population-level and patient targeted interventions to prevent the spread of mutant variants is warranted.

Risk Factors for Mortality among Adult HIV/AIDS Patients Following Antiretroviral Therapy in Southwestern Ethiopia: An Assessment through Survival Models. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2017; 14:ijerph14030296.

Abstract
Introduction: Efforts have been made to reduce HIV/AIDS-related mortality by delivering antiretroviral therapy (ART) treatment. However, HIV patients in resource-poor settings are still dying, even if they are on ART treatment. This study aimed to explore the factors associated with HIV/AIDS-related mortality in Southwestern Ethiopia. Method: A non-concurrent retrospective cohort study which collected data from the clinical records of adult HIV/AIDS patients, who initiated ART treatment and were followed between January 2006 and December 2010, was conducted, to explore the factors associated with HIV/AIDS-related mortality at Jimma University Specialized Hospital (JUSH). Survival times (i.e., the time from the onset of ART treatment to the death or censoring) and different characteristics of patients were retrospectively examined. A best-fit model was chosen for the survival data, after the comparison between native semi-parametric Cox regression and parametric survival models (i.e., exponential, Weibull, and log-logistic). Result: A total of 456 HIV patients were included in the study, mostly females (312, 68.4%), with a median age of 30 years (inter-quartile range (IQR): 23–37 years). Estimated follow-up until December 2010 accounted for 1245 person-years at risk (PYAR) and resulted in 66 (14.5%) deaths and 390 censored individuals, representing a median survival time of 34.0 months ( IQR: 22.8–42.0 months). The overall mortality rate was 5.3/100 PYAR: 6.5/100 PYAR for males and 4.8/100 PYAR for females. The Weibull survival model was the best model for fitting the data (lowest AIC). The main factors associated with mortality were: baseline age (>35 years old, AHR = 3.8, 95% CI: 1.6–9.1), baseline weight (AHR = 0.93, 95% CI: 0.90–0.97), baseline WHO stage IV (AHR = 6.2, 95% CI: 2.2–14.2), and low adherence to ART treatment (AHR = 4.2, 95% CI: 2.5–7.1). Conclusion: An effective reduction in HIV/AIDS mortality could be achieved through timely ART treatment onset and maintaining high levels of treatment adherence.

Abstract
OBJECTIVE To describe pediatric ART scale-up in Ethiopia, one of the 21 global priority countries for elimination of pediatric HIV infection. METHODS A descriptive analysis of routinely collected HIV care and treatment data on HIV-infected children (<15 years) enrolled at 70 health facilities in four regions in Ethiopia, January 2006-September 2013. Characteristics at enrollment and ART initiation are described along with outcomes at 1 year after enrollment. Among children who initiated ART, cumulative incidence of death and loss to follow-up (LTF) were estimated using survival analysis. RESULTS 11 695 children 0-14 years were enrolled in HIV care and 6815 (58.3%) initiated ART. At enrollment, 31.2% were WHO stage III and 6.3% stage IV. The majority (87.9%) were enrolled in secondary or tertiary facilities. At 1 year after enrollment, 17.9% of children were LTF prior to ART initiation. Among children initiating ART, cumulative incidence of death was 3.4%, 4.1% and 4.8%, and cumulative incidence of LTF was 7.7%, 11.8% and 16.6% at 6, 12 and 24 months, respectively. Children <2 years had higher risk of LTF and death than older children (P < 0.0001). Children with more advanced disease and those enrolled in rural settings were more likely to die. Children enrolled in more recent years were less likely to die but more likely to be LTF. CONCLUSIONS Over the last decade large numbers of HIV-infected children have been successfully enrolled in HIV care and initiated on ART in Ethiopia. Retention prior to and after ART initiation remains a major challenge.

Abstract
BACKGROUND Virologic and immunologic responses to antiretroviral treatment (ART) in infants may differ from older children due to immunologic, clinical, or epidemiologic characteristics. METHODS Longitudinal ART responses were modeled and compared in HIV-infected infants and children enrolled in cohorts in Nairobi, Kenya. Participants were enrolled soon after HIV diagnosis, started on ART, and followed for 2 years. Viral load decline was compared between infant and child cohorts using a nonlinear mixed effects model and CD4% reconstitution using a linear mixed effects model. RESULTS Among 121 infants, median age at ART was 3.9 months; among 124 children, median age was 4.8 years. At baseline, viral load was higher among infants than children (6.47 vs. 5.91 log10 copies/ml, P < 0.001). Infants were less likely than children to suppress viral load to less than 250 copies/ml following 6 months of ART (32% infants vs. 73% children, P < 0.0001). CD4% was higher at baseline in infants than children (19 vs. 7.3%, P < 0.001). Older children had more rapid CD4% reconstitution than infants, but failed to catch up to infant CD4%. CONCLUSION Despite substantially higher CD4% at ART initiation, viral suppression was significantly slower among infants than older children. New strategies are needed to optimize infant outcomes on ART.

Abstract
This study assessed adherence to antiretroviral therapy (ART) among people living with HIV/AIDS in Ethiopia and explored the sociocultural context in which they relate to their regimen requirements. Data were collected through semi-structured in-depth interviews with 105 patients on ART and observations held at the study clinic. We analyzed data using both qualitative and quantitative methods. Our findings indicate that study participants are highly adherent to dose but less adherent to dose schedule. Strict dose time instructions were reported as stressful and unrealistic. The discrepancy between adherence to dose and dose schedule could be explained by time perception, difficulty with the strictness of medication regimens, or beliefs about dose timing adherence. Care providers should acknowledge the complexities of medication practices and engage in shared decision-making to incorporate patients' perspectives and identify effective interventions.

Abstract
Background Treatment 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. Methods Retrospective 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. Result The 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. Conclusion The 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.

Abstract
CD4 T lymphocyte and plasma HIV RNA parameters have been used to monitor disease progression, and predict clinical course in HIV infection. Initial evaluation of these parameters was conducted in the western countries where accessible ARVs, circulating HIV subtypes and mode of transmission are different from the situation in Nigeria. This study appraised these parameters, and efficacy of generic ARVs. Consenting 106 HIV infected ARV naïve patients were enrolled. CD4 T lymphocyte and plasma HIV RNA levels were determined at interval for 24 months. Ninety eight (92.5%) of the patients who completed the follow up in strict adherence to therapy guideline were included in the analysis. Baseline median CD4 T lymphocyte increased from 114 (Range: 6-330) to highest 357 (Range: 15-1036) cells/ μ L at 18 months of therapy, while baseline median plasma viral RNA declined from 4.6 (Range: 2.6-6.0) Log10 copies/mL to undetectable level within three months of therapy. Significant CD4 T-cell restoration and plasma viral RNA decline in the study population demonstrate efficacy of the generic HAART. The importance of combined use of both parameters for evaluation of immunologic and virologic responses to ART was confirmed.

Abstract
The emergence of HIV-1 drug resistance mutations has mainly been linked to the duration and composition of antiretroviral treatment (ART), as well as the level of adherence. This study reports the incidence and pattern of acquired antiretroviral drug resistance mutations and long-term outcomes of ART in a prospective cohort from Northwest Ethiopia. Two hundred and twenty HIV-1C infected treatment naïve patients were enrolled and 127 were followed-up for up to 38 months on ART. ART initiation and patients’ monitoring was based on the WHO clinical and immunological parameters. HIV viral RNA measurement and drug resistance genotyping were done at baseline (N = 160) and after a median time of 30 (IQR, 27–38) months on ART (N = 127). Viral suppression rate (HIV RNA levels ≤ 400 copies/ml) after a median time of 30 months on ART was found to be 88.2% (112/127), which is in the range for HIV drug resistance prevention suggested by WHO. Of those 15 patients with viral load >400 copies/ml, six harboured one or more drug resistant associated mutations in the reverse transcriptase (RT) region. Observed NRTIs resistance associated mutations were the lamivudine-induced mutation M184V (n = 4) and tenofovir associated mutation K65R (n = 1). The NNRTIs resistance associated mutations were K103N (n = 2), V106M, Y181S, Y188L, V90I, K101E and G190A (n = 1 each). Thymidine analogue mutations and major drug resistance mutations in the protease (PR) region were not detected. Most of the patients (13/15) with virologic failure and accumulated drug resistance mutations had not met the WHO clinical and/or immunological failure criteria and continued the failing regimen. The incidence and pattern of acquired antiretroviral drug resistance mutations is lower and less complex than previous reports from sub Saharan Africa countries. Nevertheless, the data suggest the need for virological monitoring and resistance testing for early detection of failure. Moreover, adherence reinforcement will contribute to improving overall treatment outcomes.

Abstract
Background Helminths infections have been suggested to worsen the outcome of HIV infection by polarizing the immune response towards Th2. The purpose of this study is to determine the activity of Th2 immune response by measuring total serum IgE level during symptomatic and asymptomatic HIV infection with and without helminths co-infection and to define the role of deworming and/or ART on kinetics of serum IgE. Methods This prospective comparative study was conducted among symptomatic HIV-1 infected adults, treatment naïve asymptomatic HIV positive individuals and HIV negative apparently healthy controls with and without helminths co-infection. Detection and quantification of helminths and determination of serum IgE level, CD4+, and CD8+ T cell count were done at baseline and 12 weeks after ART and/or deworming. Results HIV patients co-infected with helminths showed a high level of serum IgE compared to HIV patients without helminths co-infection (1,688 [IQR 721–2,473] versus 1,221 [IQR 618–2,289] IU/ml; P = 0.022). This difference was also markedly observed between symptomatic HIV infected patients after with and without helminths infection (1,690 [IQR 1,116–2,491] versus 1,252 [703–2,251] IU/ml; P = 0.047). A significant decline in serum IgE level was observed 12 weeks after deworming and ART of symptomatic HIV infected patients with (1,487 versus 992, P = 0.002) and without (1,233 versus 976 IU/ml, P = 0.093) helminths co-infection. However, there was no significant decrease in serum IgE level among asymptomatic HIV infected individuals (1,183 versus 1,097 IU/ml, P = 0.13) and apparently health controls (666 IU/ml versus 571, P = 0.09) without helminths co-infection 12 weeks after deworming. Conclusions The significant decline of serum IgE level 12 weeks after deworming of both symptomatic and asymptomatic patients indicate a tendency to down-regulate the Th2 immune response and is additional supportive evidence that deworming positively impacts HIV/AIDS diseases progression. Thus, deworming should be integrated with ART program in helminths endemic areas of tropical countries.

Abstract
Immunological monitoring is part of the standard of care for patients on antiretroviral treatment. Yet, little is known about the routine implementation of immunological laboratory monitoring and utilization in clinical care in Ethiopia. This study assessed the pattern of immunological monitoring, immunological response, level of immunological treatment failure and factors related to it among patients on antiretroviral therapy in selected hospitals in southern Ethiopia. A retrospective longitudinal analytic study was conducted using documents of patients started on antiretroviral therapy. Adequacy of timely immunological monitoring was assessed every six months the first year and every one year thereafter. Immunological response was assessed every six months at cohort level. Immunological failure was based on the criteria: fall of follow-up CD4 cell count to baseline (or below), or CD4 levels persisting below 100 cells/mm3, or 50% fall from on-treatment peak value. A total of 1,321 documents of patients reviewed revealed timely immunological monitoring were inadequate. There was adequate immunological response, with pediatric patients, females, those with less advanced illness (baseline WHO Stage I or II) and those with higher baseline CD4 cell count found to have better immunological recovery. Thirty-nine patients (3%) were not evaluated for immunological failure because they had frequent treatment interruption. Despite overall adequate immunological response at group level, the prevalence of those who ever experienced immunological failure was 17.6% (n=226), while after subsequent re-evaluation it dropped to 11.5% (n=147). Having WHO Stage III/IV of the disease or a higher CD4 cell count at baseline was identified as a risk for immunological failure. Few patients with confirmed failure were switched to second line therapy. These findings highlight the magnitude of the problem of immunological failure and the gap in management. Prioritizing care for high risk patients may help in effective utilization of meager resources.

Abstract
BACKGROUND With the advent of highly active antiretroviral therapy (HAART), HIV infection has become a chronic condition in children with improved survival and quality of life. Reports on long term effectiveness of non-nucleoside reverse transcriptase inhibitor based HAART in HIV-infected children in developing countries are limited. METHODS A chart review was conducted and children who received at least six months of HAART between 2004-2011 at All India Institute of Medical Sciences (AIIMS), Delhi were included. The clinical, immunological and virological responses to HAART were documented. Factors predicting non-adherence and non-response to treatment were described. RESULTS One seventy five children (boys: 74.9%) were included in the study, with a median follow up of 43 (IQR: 17, 68) months. The median age at diagnosis was 119 (IQR: 75, 156) months. The median CD4 count at start of HAART was 340 cells/μL (IQR: 185,704), which increased to 924 cells/μL (IQR: 591,1278) at 48 months after HAART and plateaued at 749 (IQR: 542,1056) cells/ μL after 90 months of therapy. The weight for age (WAZ) and height for age (HAZ) z score both showed improvement with time after HAART initiation [baseline: WAZ -2.8 (IQR: -4,-1.6), HAZ -2.1 (IQR: -3.4,-0.69); at 42 months of therapy: WAZ -1.2 (IQR: -2.1, 0.01), HAZ -0.75(IQR: -1.6,-0.37)]. Adverse events were reported in 21 (12%) children. Non-adherence to therapy, treatment failure and death were noted in 35 (20%), 9 (5.1%) and 6 (3.4%) children respectively. CONCLUSIONS Our experience shows that HAART in HIV-infected children is effective, safe and is associated with good immunological and virological response as well as improvement in growth parameters.

Abstract
Background Antiretroviral therapy (ART) reduces HIV-related mortality and morbidity substantially in children. The clinical characteristics, immunological and virological outcomes were evaluated in HIV-infected children receiving ART. Methods Twenty-six HIV-1-infected children receiving ART in Hubei province, China, were enrolled retrospectively in this study. During the period of ART, plasma viral load, lymphocyte phenotype of CD4 and CD8 cells and clinical events were assessed. Results The median duration of ART was 41 months (18–72.3 months). In children showing clinical improvement, high viral suppression rate below log10 (2.7) copies/ml by the third months of ART was observed. The median CD4 cell counts reached to 820.5/μl by 12 months and the median ratio of CD4/CD8 increased to 0.6 by 21 months. The counts of peripheral white blood cells and red blood cells decreased in the first 12 months, while Hb concentration, MCV and MCH increased (P < 0.001). Conclusions Despite the limited small sample size, ART is an effective strategy for inhibiting HIV replication and reconstructing the immunological response in children with AIDS.

BMC Infect Dis 2014; 14:158. [PMID: 24655349 PMCID: PMC3976149 DOI: 10.1186/1471-2334-14-158] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2014] [Accepted: 03/18/2014] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Despite the increasing use of antiretroviral treatment (ART) recent data on frequency and pattern of drug resistance mutations in Ethiopia is not available. Furthermore with increasing mobility of people HIV-1 subtypes other than the predominant subtype C may likely be introduced from the neighbouring countries. This study was aimed to determine the molecular characterization and pre-antiretroviral treatment resistance mutations among HIV-1 chronically infected ART naïve patients after the roll out of ART in Ethiopia. METHODS Viral RNA was determined in 160 baseline plasma samples. The entire PR and the first 335 codons (76%) of the RT regions of the pol gene of the HIV-1 genome (N = 160) were amplified and sequenced using an in-house assay. Genotypic drug resistance was defined as the presence of one or more resistance-related mutations as specified by the consensus mutation of Stanford University HIVDB and the International Antiviral Society (IAS) mutation lists. RESULTS A predominance of HIV-1 subtype C (98.7%) was observed. The level of drug resistance is found to be 5.6% and 13.1% according to the Stanford University HIVDB drug resistance interpretation algorithms and the International Antiviral Society mutation lists, respectively. Mutations conferring simultaneous resistance to NRTIs and NNRTIs were not detected and no major PR mutation was found. However, a high rate of polymorphic changes both in PR and RT regions were observed. Moreover, twenty four (15%) monophyletic transmission clusters with bootstrap value of 99% were found. CONCLUSIONS Strong evidence for consistent HIV-1C clade homogeneity and low influx of other variant into the country was found. The level of drug resistance observed in chronically infected treatment naïve patients which exceeds the WHO estimates suggests the need for incorporation of HIV-1 drug resistance testing prior to ART initiation. The occurrence of monophyletic transmission clusters affecting (24/160) individuals indicates their potential risk related practice. Thus, an intensified public health intervention program and monitoring of HIV drug resistance testing appears indispensible.
