[PMID: 38880895 PMCID: PMC11181533 DOI: 10.1186/s40001-024-01934-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Accepted: 06/09/2024] [Indexed: 06/18/2024] Open
Abstract
BACKGROUND Adverse drug events (ADEs) represent challenges affecting Africa's healthcare systems owing to the increased healthcare expenditure and negative health outcomes of ADEs. OBJECTIVES We aimed to systematically review published studies on ADEs and synthesize the existing evidence of ADE prevalence in Africa. METHODS Studies reporting on ADE occurrence in African settings and published from Jan 1, 2000 to Oct 1, 2023 were identified by searching PubMed, EBSCO, Science Direct, and Web of Science. Studies that either articulately investigated ADEs caused by clinical condition (such as HIV patients) or ADEs caused by exposure to specific drug(s) (such as antibiotics) were considered specific and the remaining were general. Grouped ADE prevalence rates were described using median and interquartile range (IQR). PROSPERO registration (CRD42022374095). RESULTS We included 78 observational studies from 15 African countries that investigated the prevalence of ADEs leading to hospital admissions (17 studies), developed during hospitalizations (30 studies), and captured in the outpatient departments (38 studies) or communities (4 studies). Twelve studies included multiple settings. The median prevalence of ADE during hospitalization was 7.8% (IQR: 4.2-21.4%) and 74.2% (IQR: 54.1-90.7%) in general and specific patients, respectively. The ADE-related fatality rate was 0.1% and 1.3% in general and specific patients. The overall median prevalence of ADEs leading to hospital admissions was 6.0% (IQR: 1.5-9.0%); in general, patients and the median prevalence of ADEs in the outpatient and community settings were 22.9% (IQR: 14.6-56.1%) and 32.6% (IQR: 26.0-41.3%), respectively, with a median of 43.5% (IQR: 16.3-59.0%) and 12.4% (IQR: 7.1-28.1%) of ADEs being preventable in general and specific patients, respectively. CONCLUSIONS The prevalence of ADEs was significant in both hospital and community settings in Africa. A high ADE prevalence was observed in specific patients, emphasizing important areas for improvement, particularly in at-risk patient groups (e.g., pediatrics, HIV, and TB patients) in various settings. Due to limited studies conducted in the community setting, future research in this setting is encouraged.

Evaluation of Adverse Drug Events in Patients on Anti-Retroviral Therapy Regimen at Omdurman Voluntary Counselling and Testing and Anti-Retroviral Therapy Center in Sudan - A Cross-Sectional Study. HIV AIDS (Auckl) 2024; 16:153-164. [PMID: 38659445 PMCID: PMC11042483 DOI: 10.2147/hiv.s449900] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Accepted: 04/13/2024] [Indexed: 04/26/2024] Open
Abstract
Background Anti-retroviral therapy-related adverse drug events are accounted as a main cause of anti-retroviral therapy non-adherence. In Sudan, pharmacovigilance studies are relatively rare and obstructed by the problem of under-reporting. It is a well-defined issue worldwide and is highly reported in developing countries. This study aimed to evaluate the prevalence of adverse events associated with anti-retroviral therapy among adult patients with immunodeficiency virus at Omdurman Voluntary Counselling and Testing and Anti-retroviral Therapy Center. Methods The study was a descriptive cross-sectional study conducted through direct interviews with 429 patients at the selected center using the Adverse Drug Events (ADEs) reporting form. The collected data were analyzed by The Statistical Package for Social Sciences. Results More than half (55.5%) of the participants experienced adverse events, with 48.7% having experienced them at the beginning of treatment. Central nervous system manifestations were the most common adverse events. By using the Naranjo scale, most adverse events showed a "probable" relationship to anti-retroviral medicines. Based on the chi-square test, medication regimen was significantly associated with the presence of ADEs (namely abdominal pain and jaundice) (p values = 0.03 and 0.001), respectively. Conclusion This study clearly stated that ART-related ADEs are common among Sudanese PLHIV and with central nervous system being the main adverse events. More pharmacovigilance studies and efforts by healthcare providers should be applied targeting ART-related ADEs under-reporting in Sudanese healthcare facilities.

Understanding the role of religious beliefs in adherence to antiretroviral therapy among Pentecostal Christians living with HIV in sub-Saharan Africa: a scoping review. BMC Public Health 2023; 23:1768. [PMID: 37697279 PMCID: PMC10494378 DOI: 10.1186/s12889-023-16616-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Accepted: 08/25/2023] [Indexed: 09/13/2023] Open
Abstract
BACKGROUND Optimum adherence to antiretroviral therapy (ART) is crucial in managing HIV. However, some people's religious beliefs can influence how they deal with HIV and the psychosocial factors influencing their adherence to ART, such as disclosure, acceptance of HIV status, belief in ART, and depression. In sub-Saharan Africa (SSA), the role of religious beliefs in ART adherence is underexplored. We aimed to identify and conceptualize the literature on religious beliefs concerning ART adherence among Pentecostal Christians living with HIV in SSA. METHODS We conducted a scoping review of the literature on religious beliefs and ART adherence. We searched papers from PubMed, Web of Science, Medline, Sabinet, Academic Search Complete, CINAHL Plus, Health Source/Nursing Academic, Scopus, and Google Scholar and published papers from conference proceedings and dissertations. Data were extracted according to a predetermined population, concept, context framework, and eligibility criteria for selecting or rejecting studies. We used a narrative synthesis to summarize the data on evidence and the impact of religious beliefs on ART adherence. RESULTS Seven papers published between January 2010 and February 2022 met the inclusion criteria. Nineteen aspects of religious beliefs were identified as negatively influencing ART adherence, while eight aspects facilitated optimal adherence. "Being saved" or "born again" enhanced coping strategies for optimal adherence through actions such as less alcohol use, fidelity to a sexual partner(s), disclosure, acceptance of HIV status, reduced depression, and facilitated PLHIV to access social support from church members or other institutions. CONCLUSION Religious beliefs are integral to Pentecostal Christians living with HIV and affect their adherence to ART. While some Pentecostal Christians living with HIV on ART use their religious beliefs and practices to access psychosocial support from other church members or organizations and achieve good clinical outcomes, others apply their religious beliefs and practices differently and compromise their commitments to taking ART as prescribed, thus experiencing poor viral suppression and clinical outcomes. However, more research is required to understand and theorize how religious beliefs impact ART adherence among Pentecostals living with HIV to inform guidelines for practitioners.

Optimizing Antiretroviral Therapy in Heavily ART-Experienced Patients with Multi-Class Resistant HIV-1 Using Proviral DNA Genotypic Resistance Testing. Viruses 2023; 15:1444. [PMID: 37515133 PMCID: PMC10384096 DOI: 10.3390/v15071444] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 06/20/2023] [Accepted: 06/22/2023] [Indexed: 07/30/2023] Open
Abstract
Resistance to multiple antiretroviral drugs among people living with HIV (PLWH) can result in a high pill burden, causing toxicity and drug interactions. Thus, the goal is to simplify treatment regimens while maintaining effectiveness. However, former resistance analysis data may not be current or complete. The use of proviral DNA genotyping may assist in selecting appropriate treatment options. A retrospective study was carried out on individuals belonging to the Cologne HIV cohort with a resistance history to two or more antiretroviral (ARV) classes and on non-standard antiretroviral therapy (ART). Patients required former viral RNA and a recent proviral DNA resistance test to be available prior to the switch to ART. Potential discrepancies between resistance test results obtained through RNA and proviral DNA methods and the consequent virological and clinical outcomes following ART adjustments were analyzed. Out of 1250 patients, 35 were eligible for inclusion in this study. The median length of known HIV infection was 27 years, and the median duration of ART was 22 years. Of the 35 participants, 16 had received all five ARV classes. Based on proviral DNA genotyping results, ART was simplified in 17 patients. At the last follow-up examination after changing therapy, 15 patients had HIV RNA <50 copies/mL (median 202 days, range 21-636). The mean number of pills per day decreased from eight to three, and the median intake frequency decreased from two to one time/day (ranges 1-2). Our study supports the use of proviral DNA genotyping as a safe strategy for switching to simplified ART regimens. However, the lack of extensive research on the advantages of proviral DNA genotyping makes it challenging to fully assess its benefits in terms of treatment selection.

Abstract
INTRODUCTION There are presently over four million people living with HIV (PLHIV) in the South African national antiretroviral therapy (ART) programme. However, some ART programmes are battling poor ART adherence emanating from patient-related factors, including their religious beliefs. In this paper, we outline a study protocol to understand the adherence behaviours of Pentecostal Christians living with HIV to ART and to develop guidelines that can be used to strengthen ART adherence. METHODS AND ANALYSIS We propose an exploratory multimethod research design. In phase 1, a scoping review will be conducted. The data captured in this phase will be put into charting forms, analysed qualitatively, and then collated and summarised to hypothesise the relationship between religious beliefs and ART adherence. In phase 2, an explanatory qualitative approach will be used. Semistructured interviews will be conducted with purposefully selected religious leaders, Pentecostal Christians living with HIV who are not adhering to ART and healthcare workers delivering ART at selected healthcare facilities in the Milnerton subhealth district. The qualitative data obtained in this phase will be transcribed verbatim and analysed thematically using the ATLAS.ti V.8 software program towards strengthening the hypothesised relationship between religious beliefs and ART adherence. In phase 3, intervention mapping and nominal group techniques will be applied with purposefully selected stakeholders to develop guidelines to strengthen ART adherence among PLHIV. ETHICS AND DISSEMINATION Phase 1 of the study will not require ethics approval. Ethics approval for phases 2 and 3 has been received from the University of the Western Cape Biomedical Research and Ethics Committee and the Western Cape Department of Health. Informed consent forms will be obtained from all participants at the different phases of the study. The study findings will be disseminated through publications in scientific journals, presentations at conferences and workshops aimed at improving ART adherence.

Abstract
Background The proportion of HIV patients on second-line antiretroviral therapy is becoming a growing public health concern, especially in a low-income country setting. However, unlike first-line therapy, to date, very little is known about the outcomes of second-line therapy in the Ethiopia context. Thus, this study was conducted to determine the rate of treatment failure, death, and their predictors among HIV patients receiving second-line therapy. Methods A retrospective cohort study was conducted on 642 people living with HIV in Dessie Comprehensive Specialized Hospital from October 2016 to November 2019. Poisson and competitive risk survival models were computed to explore predictors of treatment failure and death, respectively. Results During follow-up period, 39 (6.87%, 95% CI: 5–9.2%) of 568 patients had second-line treatment failure with 4.07 per 100 person-year rate of failure. Being on anti-TB treatment [Rate ratio, RR = 2.57 (95% CI: 1.25–5.25)], not having optimal medication adherence [RR = 2.29 (95% CI: 1.09–4.78)], and not timely switched [RR = 5.89 (95% CI: 1.36–25.54)] were positively associated with treatment failure. Similarly, 44 (6.85%, 95% CI: 5–9%) of 642 patients died with 4.5 per 100 person-year rate of death. Being on advanced clinical condition [Sub distribution Hazard ratio, SHR = 2.49 (95% CI: 1.31–4.74)], not having optimal medication adherence [SHR = 2.65 (95% CI: 1.31–4.74)], lower CD4 cell counts, and high viral load measurement were positively associated with death. Conclusions A significant number of patients had failed to respond to second-line therapy. A large number of patients had also died. Patient medical profile and monitoring practice were associated with treatment failure and death. Hence, patient-centered monitoring and interventions should be strengthened, besides treatment switch.

Abstract
INTRODUCTION Sub-Saharan Africa continues to be disproportionately affected by HIV/AIDS. As such, several countries in sub-Saharan Africa are implementing the UNAIDS' recommendation to test and treat people living with HIV (PLHIV) irrespective of their CD4 count. However, most of the antiretroviral treatment (ART) programmes, in this region, continue to struggle with poor adherence to treatment stemming from patient-related factors including their religious beliefs. Unfortunately, the role of religious beliefs on ART adherence has been underexplored in the literature. In this study protocol, we propose the steps of a scoping review to explore, identify and map the literature on the impact of religious beliefs on adherence to ART among Pentecostals living with HIV in sub-Saharan Africa. METHODS AND ANALYSIS We will use Arksey and O'Malley's framework and the Joanna Briggs Institute methodology guidelines to conduct this scoping review. The following databases will be searched for relevant literature: Web of Science, PubMed/Medline, Psych-ARTICLES, Academic Search Complete, Cumulative Index of Nursing, Allied Health, Google Scholar and published articles from conference proceedings. Studies published between January 2010 and February 2022 will be eligible. The identified literature will be independently screened for eligibility by two reviewers based on predetermined inclusion and exclusion criteria. An Excel form will be designed to electronically capture data from studies that meet the inclusion criteria. Finally, we will use a narrative synthesis to summarise the data extracted to report on the nature of existing evidence and the impact of religious beliefs on ART adherence. ETHICS AND DISSEMINATION Ethical approval will not be required for the scoping review since it will entail synthesising information from already published articles and conference proceedings. The study findings will be disseminated through publication in a scientific journal and presented at conferences and workshops aimed at improving adherence to ART in PLHIV.

Abstract
Background In Ethiopia, first-line antiretroviral therapy failure is growing rapidly. However, unlike first-line therapy, to date, very little is known about the outcomes of second-line therapy. Thus, this study assessed the rate of viral re-suppression and attrition to care and their predictors among people living with HIV on second-line therapy. Methods A retrospective cohort study was conducted on 642 people living with HIV at Dessie Comprehensive Specialized Hospital from October 2016 to November 2019. A proportional Cox regression model was computed to explore predictors of viral re-suppression (viral load less than 1000 copies/mL) and attrition to care. Results Out of 642 subjects, 19 (3%), 44 (6.9%), 70 (10.9%), and 509 (79.3%) patients were lost to follow up, died, transferred out, and alive on care, respectively. Similarly, 82.39% (95% CI: 79.24–85.16%) of patients had achieved viral re-suppression, with 96 per 100 person-year rate of re-suppression. Patients who switched timely to second-line therapy were at a higher rate of viral re-suppression than delayed patients [adjusted hazard rate, AHR = 1.43 (95% CI: 1.17–1.74)]. Not having drug substitution history [AHR = 1.25 (95% CI: 1.02–1.52)] was positively associated with viral re-suppression. In contrast, being on anti-TB treatment [AHR = 0.67 (95% CI: 0.49–0.91)] had lower likelihood with viral re-suppression. In the current study, attrition to care was 11% (95% CI: 8.7–13.9%). Ambulatory or bedridden patients were more at risk of attrition to care as compared with workable patients [AHR = 2.61 (95% CI: 1.40–4.87)]. Similarly, being not virally re-suppressed [AHR = 6.87 (95% CI: 3.86–12.23)] and CD4 count ≤450 cells/mm3 [AHR = 2.61 (95% CI: 1.40–4.87)] were also positively associated with attrition to care. Conclusion A significant number of patients failed to achieve viral re-suppression and attrition from care. Most identified factors related to patient monitoring. Hence, patient-centered intervention should be strengthened, besides treatment switch.

Abstract
The human immunodeficiency virus (HIV) is a viral infection that destroys the human immune system resulting in acquired immunodeficiency syndrome (AIDS). The Zambia HIV prevalence rate (11.3%) remains among the highest in the sub-Saharan Africa. In the treatment of HIV-naive patients, a problem that relates to the transmitted drug resistance mutation strains (TDRMs) occurs in the administration of antiretroviral (ARV) drugs. To address this problem, we propose the use of transition probabilities when prescribing a switch from the first-line to the second-line or to the third-line regimen on the ARV drugs combination. We formulate a statistical technique to determine an optimal ARV drugs combination. To compute a transition probability matrix chart on ARV drugs combinations of the first-line and second-line regimens, we apply a beta-binomial hierarchical model on HIV data. The transition probability matrices corresponding to the ARV drugs combinations TDF+ETC+NVP, TDF+FTC+EFV, AZT+3TC+NVP, AZT+3TC+EFV, D4T+3TC+NVP, and D4T+3TC+EFV provide an upper triangular matrix of probabilities. We observe a higher probability of remaining in the same regimen state than moving to another state. A transition probability chart provides information on the most effective combination to prescribe to a patient in the presence of transmitted drug resistance mutation (TDRM) test results. The transmission probabilities play a major role in aiding the physicians make an informed decision to prescribe an optimal ARV drugs combination. We suggest a TDRM test to be carried out to all newly diagnosed HIV individuals before prescribing any of the ARV drugs combination.

Abstract
Background Besides its contribution in the treatment of Human Immunodeficiency Virus-infected patients, anti-retroviral drugs may also cause mild to serious adverse effects. It is the main causes for poor drug adherence, treatment discontinuation and changes in Anti-Retroviral Treatment (ART) regimens. Thus, the aim of this study was to assess the incidence and predictors of adverse drug reaction among adult Human Immunodeficiency Virus positive patients on anti-retroviral treatment from January 1, 2013 up to December 30, 2018 at Arba Minch town public health facilities, Southern Ethiopia. Methods An institution based retrospective cohort study was conducted on 456 charts. Secondary data was collected by structured questionnaire. Data were entered in Epi-data version 4.4.2 software and exported to STATA Version 14 for analysis. The Kaplan-Meier survival curve with Log-rank was used to estimate survival time. Bi-variable and multivariable Cox proportional hazard regression models were fitted to identify predictors of adverse drug reaction. In the bi-variable analysis, the variables with p-value < 0.25 were eligible for multivariable analysis. Finally, variables with p-values less than 0.05 in the multivariable Cox regression were considered as independent predictors. The statistical significance was declared at p-value<0.05. Results Out of 456 patients observed for 14,903 person-months (pm), 79 experienced adverse drug reactions and the overall incidence density rate was 0.53/100 pm, CI: 0.42–0.66/100 person’s month or 6.36 per 100 Pearson year of observation. Females were at higher risk of experiencing adverse drug reactions (ADRs) compared to males [AHR = 2.35; CI (1.18, 4.69)]. The risk of experiencing ADRs among patient with advanced WHO clinical stage (stage III and IV) was higher compared to stage I and II [AHR = 3.0, CI (1.22, 7.37)]. The risk of experiencing an ADR was at any given time higher among AZT and NVP containing regimens compared to TDF and EFV containing regimens. Finally, the risk of ADR among those patients from the health center was reduced by 59% compared to hospital patients, [AHR = 0.41, CI (0.17, 0.97)]. Conclusion and recommendation The incidence rate of ADRs was reduced among patients on ARVs compared to previous studies and it was high during the early years of ART initiation. HIV patients should be closely followed in the early years of ART initiation, since this is the time of highest risk ADRs and emphasis should be given for female and clinically advanced patients.

A Case -Control Study. HIV AIDS (Auckl) 2020; 12:749-756. [PMID: 33239920 PMCID: PMC7680783 DOI: 10.2147/hiv.s267629] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2020] [Accepted: 10/29/2020] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND Virological failure is defined as having viral load measurement greater or equal to 1000 copies/mm3 after at least six-month exposure to antiretroviral therapy. According to the Joint United Nations Programme on HIV/AIDS (UNAIDS-2018) report, globally nearly one in five patients on first-line antiretroviral therapy had experienced virological failure. In line with this, Ethiopia federal ministry of health also reported that one in four patients had experienced virological failure in the year 2016. To date, very little is known about the predictors of virological failure in the local context. Therefore, this study intended to address the determinants of virological failure among patients on a first-line antiretroviral regimen. METHODS A case-control study was conducted among clients on first-line antiretroviral therapy in Amhara regional state, January 2019 with a sample of 257 clients; of these, 86 clients were cases. Data were collected via patient interview and chart extraction for clinical profiles using standardized tools. Binary logistic regression was computed to identify the determinants of virological failure using Stata version 14 and the result was displayed using adjusted odds ratio with a 95% confidence interval. RESULTS Out of the proposed samples, 255 clients were considered for final analysis. The odds of virological failure are higher among poor medication adherence (AOR: 10.2:95% CI [4.1-25.8]), age<35 years (AOR: 3.07 95% CI 1.4-6.8), low baseline CD4 (AOR 3.9: 95% CI 1.6-9.6), and Khat chewers (AOR: 9.5:95% CI 2.8-32.4) as compared with their counterparts. CONCLUSION Being a young age, poor immunity at the initiation of antiretroviral, Khat chewer, and poor medication adherence significantly associated with virological failure.

Abstract
PURPOSE Adverse drug reactions (ADRs) have an appreciable impact on patients' health. Little is known however about ADR reporting in ambulatory care environments especially in low- and middle-income countries. Consequently, our aim was to determine knowledge, attitudes and practices (KAP) among health care professionals (HCPs) towards ADR reporting in primary health care (PHC) facilities in South Africa. The findings will be used to direct future activities. METHODS Descriptive, cross-sectional design using quantitative methodology among 8 public sector community health care centres and 40 PHC clinics in the Tshwane Health District, Gauteng Province. A self-administered questionnaire was distributed to 218 HCPs, including all key groups. RESULTS A total of 200 responses were received (91.7%). Although an appropriate attitude towards ADR reporting existed, the actual frequency of ADR reporting was low (16.0%). Of the respondents, 60.5% did not know how to report, where to report or when to report an ADR and 51.5% said the level of their clinical knowledge made it difficult to decide whether or not an ADR had occurred. Over 97.5% stated they should be reporting ADRs with 89% feeling that ADR reporting is a professional obligation and over 70% that ADR reporting should be compulsory. When results were combined, the overall mean score in terms of positive or preferred practices for ADR reporting was 24.6% with pharmacists having the highest scores. CONCLUSION Under-reporting of ADRs with gaps in KAP was evident. There is a serious and urgent need for education and training of HCPs on ADR reporting in South Africa.

Abstract
Background Treatment failure has become a significant challenge in patients taking antiretroviral therapy (ART). The aim of the present study was to identify risk factors for first-line ART failure among patients attending clinical follow-up. Methods A 1:2 matched case-control study (by age, sex, and treatment duration since initiated on ART) was conducted from June 2015 to July 2017 on adult patients (aged ≥15 years) who were on ART for at least 6 months. Cases were selected from patients who were switched to second-line ART after first-line ART failure (viral load ≥1000 copies/mL). Controls were randomly selected from patients on first-line ART with viral load < 50 copies/mL. Data were collected using an interview questionnaire, reviewing chart and electronic health records and laboratory tests. Multivariate logistic regression analysis was performed to identify risk factors for treatment failure. Results Of the 273 patients who participated in this study, 55% were males. Ninety-one cases were compared with 182 controls. The median age of participants was 40 years and the median duration of treatment since initiated on ART was 69 months. Independent risk factors associated with first-line antiretroviral treatment failure were discontinuation of ART (adjusted odds ratio (AOR) = 9.8, 95% confidence interval (CI): 4.0–23.8), baseline CD4 lymphocyte count ≤50 cells/mm3 (AOR = 3.8, 95% CI: 1.5–9.6) and persistent diarrhea (AOR = 4.4, 95% CI: 1.5–13.2). The risk of ART failure was high and comparable whether the duration of ART discontinuation was greater or less than 1 month (crude odds ratio (COR) = 6.3 and 8. 5 respectively, p-value < 0.001). Frequent eating of a diet containing wheat or barley (AOR = 2.3, 95% CI: 0.9–5.4) showed a trend to be a risk factor for first-line ART failure (p-value = 0.064). Conclusions Our findings underscore the importance of avoiding ART discontinuation of any duration, early initiation of ART and diarrhea management to prevent first-line ART failure.
