Incidence of common opportunistic infections among HIV-infected children on ART at Debre Markos referral hospital, Northwest Ethiopia: a retrospective cohort study

Survival analysis and predictors for hemoglobin level and time-to-default from HIV treatment among first-line female HIV-positive patients within the reproductive age group

Ethiopia has the highest proportion of the HIV population receiving ART of any African country. The objective of this study was to identify survival analysis and predictors for hemoglobin level and time-to-default from HIV treatment among first-line female HIV-positive patients within the reproductive age group. Secondary data source conducted at the University of Gondar Comprehensive Specialized Hospital from September 2015 to March 2022. In this study, the generalized linear mixed model and the Cox PHs model were jointly used to get a wide range of information about female HIV data. The mean (standard deviation) of white blood cells and red blood cells was 6.11 (1.8) and 4.02 (1.26), respectively. Out of 201 study participants, 27.9% defaulted from treatment, and the remaining were considered censored. In this study, the association parameter (gamma_1) for hemoglobin level and default from HIV treatment is negative and statistically significant ([Formula: see text]) at the 5% level of significance. These findings suggested that the patient's association parameter had an inverse link with hemoglobin and treatment default. The result of the study also shows low red blood cell and white blood cells lead to low hemoglobin levels and a high hazard of defaulting. Likewise, patients under the categories of World Health Organization (WHO) clinical stage III and IV, ambulatory, bedridden, primary education, Opportunistic Infections (OIs), and substance abuse were at high hazard of being defaulters. Conversely, secondary and tertiary education and patients expressing diseases status to family members were low hazards for defaulters. In addition, WHO clinical stage III and IV patients, bedridden patients, primary educators, OIs, and substance abusers had low hemoglobin level concentrations, and tertiary education and disclosing the diseases to family members were high hemoglobin level concentrations. Healthcare workers in similar settings should pay more attention to clients related to hemoglobin levels and time to default from medication based on these important factors.

Inflammation-related indices as markers for mortality in people living with HIV co-infected with Talaromyces Marneffei: a retrospective analysis

Talaromyces marneffei (T. marneffei) co-infection remains a significant cause of mortality in people living with HIV (PLWH). Although early detection of individuals at high risk is essential, there remains a lack of markers to predict outcomes. This multicenter retrospective study analyzed 282 PLWH (95 treatment-naïve T. marneffei co-infected, 187 without opportunistic infections) to evaluate six inflammatory indices: systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), neutrophil-to-platelet ratio (NPR), and pan-immune inflammation value (PIV). Multivariate logistic regression and ROC analysis were performed to identify risk factors and prognostic performance. The results revealed that T. marneffei group exhibited significantly elevated levels of SII, NPR, NLR, and PLR (P <0.001), with lower LMR (P <0.001) and PIV levels (P =0.014). Logistic regression identified thrombocytopenia (P =0.026), hypoalbuminemia (P =0.031), and lower CD4+ T-cell counts (P =0.011) as independent predictors of HIV-TM coinfection. Among the T. marneffei group, survivors (n=80) and non-survivors (n=15) exhibited distinct inflammatory profiles: NLR demonstrated optimal mortality prediction (AUC=0.788, P <0.001), outperforming NPR (AUC=0.671, P <0.001). Multivariate analysis confirmed NLR as the sole mortality predictor (P =0.041), with restricted cubic spline analysis indicating a non-linear NLR-mortality relationship. In conclusion, we found that NLR represents a reliable prognostic marker for PLWH co-infected with T. marneffei.

Incidence and predictors of common opportunistic infections among children less than 15 years of age on antiretroviral therapy in Ethiopia: a systematic review and meta-analysis

BACKGROUND

Despite significant efforts to enhance access to antiretroviral therapy (ART), opportunistic infections among children on ART remain a major concern in low-income countries, including Ethiopia. Currently, there are no pooled estimates of opportunistic infections incidence among children on ART in Ethiopia. Consequently, this review aimed to determine the pooled incidence and identify the predictors of opportunistic infections among children under 15 years of age on ART, addressing the existing information gap.

METHODS

This systematic review followed the PRISMA guidelines, and relevant studies were obtained from the PubMed, CINAHL, Scopus, EMBASE, and Google Scholar databases. Data analysis for pooled estimates of incidence and predictors of opportunistic infections was conducted via STATA 17 software with random-effects model. Heterogeneity was evaluated via Cochrane's Q-test and the I2 statistic, and publication bias was assessed through funnel plots and Egger's test.

RESULTS

Of the 5,631 studies identified, 20 studies involving 9,196 participants were included in the meta-analysis. The pooled incidence of opportunistic infections among children under 15 years of age on antiretroviral therapy was 5.61 per 100 person-years (95% CI: 4.37-6.86), based on 36,716.4 person-years of observation. Predictors of opportunistic infections included advanced WHO clinical stage (HR 1.45, 95% CI: 1.35-1.55), poor ART adherence (HR 1.49, 95% CI: 1.35-1.63), lack of isoniazid (HR 1.56, 95% CI: 1.40-1.74) and cotrimoxazole preventive therapy (HR 1.56, 95% CI: 1.38-1.66), malnutrition (HR 1.50, 95% CI: 1.34-1.67), and severe immunosuppression (HR 1.39, 95% CI: 1.27-1.51).

CONCLUSION

The incidence of opportunistic infections in this review was high, highlighting the need for intensified efforts to achieve the 2030 target. Moreover, advanced WHO clinical stage, poor adherence, lack of isoniazid and cotrimoxazole preventive therapy, malnutrition, and severe immunosuppression were identified as predictors of opportunistic infections. This suggests that early initiation of ART, regular nutritional assessments, intensive follow-up and monitoring, and a multidisciplinary approach need be prioritized to address the identified predictors.

Prevalence of Opportunistic Infections and Determinants Among HIV-Positive Patients in Ethiopia: A Systematic Review and Meta-Analysis

Background and Aims

Opportunistic infections (OIs) associated with HIV are the primary cause of morbidity and mortality among individuals living with HIV/AIDS. Evaluating the extent of OIs at the national level is essential for developing targeted interventions and effective control measures. Therefore, the aim of this study was to evaluate the pooled prevalence and identify the associated factors of OIs among HIV-positive individuals across all age groups.

Methods

This systematic review and meta-analysis was conducted following the PRISMA guidelines. It included studies published in English, research articles conducted in Ethiopia, and articles released between 2013 and 2023. A systematic search of articles on the prevalence and determinants of OIs among patients living with HIV in Ethiopia was conducted across four databases (PubMed, ScienceDirect, Scopus, and the Cochrane Library). To evaluate heterogeneity and publication bias, the study employed Cochran's Q, inverse variance (I2), sensitivity analysis, funnel plots, and Begg and Egger regression tests. The meta-analysis was executed using STATA software, version 14.

Results

Of the 207 articles examined, only 26 met the inclusion requirements. The overall prevalence of OIs among HIV-positive patients was 42.71% (95% CI: 36.87-48.56). OIs among HIV-positive individuals were significantly associated with baseline WHO clinical stage II and above (OR: 2.83; 95% CI: 1.93-3.73), khat chewers (OR: 1.94; 95% CI: 1.21-2.66), poor adherence to ART (OR: 2.32; 95% CI: 1.51-3.13), and individuals with an initial CD4 number less than 200 cells/mm3 (OR: 2.32; 95% CI: 1.55-3.09).

Conclusion

Chewing khat, poor adherence, low CD4 count, and WHO stage II and above were found to be predictors of OIs. A constant state of awareness is required for healthcare providers to improve decisions about the proper diagnosis and management of OIs among HIV-positive individuals.

Opportunistic infections among schoolchildren who were on antiretroviral therapy in Ethiopia: a systematic review and meta-analysis

Introduction

The most common and severe cause of morbidity and mortality among HIV- positive children is opportunistic infections (OIs). All HIV-infected children are at risk of developing a variety of OIs. Healthcare workers, programmers, and other stakeholders are in doubt about using the onset and predictors of OIs among schoolchildren on antiretroviral therapy (ART) due to the presence of conflicting results found in the primary studies. Hence, this study was conducted to provide a single figure of onset and specific predictors of OIs by overcoming the existing heterogeneity in Ethiopia.

Methods

The included studies were searched from different national and international databases systematically. The included studies were cohort in design and published in English between 2015 and 2022. The data were extracted using a validated Microsoft Excel tool after the quality of the included studies was assured. The extracted data were exported to Stata Version 17.0 for further management and analysis. The presence of heterogeneity across studies was checked using the Chi-square test and quantified using the I 2 test. Various methods, including forest plots, publication bias assessment, sensitivity tests, subgroup analysis, and meta-regression, were employed to determine the source of heterogeneity, but none were successful. The overall onset of OIs was estimated by pooling the incidence of primary studies using a random-effects meta-analysis model. The predictors were identified using meta-regression and the presence of significant association was declared using a p-value of 0.05 with 95% CI. The strength of association was reported using an adjusted hazard ratio with 95% CI.

Results

Eleven studies were included in this systematic review and meta-analysis. The onset of OIs among schoolchildren on ART in Ethiopia was 5.58 (95% CI: 4.50, 6.67) per 100 children-years of OI-free observations. Those children who had no parents had a 1.41 (95% CI: 1.10, 1.80) times higher chance of getting OIs when compared with those children having one or both parents. Children who had poor ART adherence had a 2.96 (95% CI: 1.66, 5.29) times higher chance of experiencing OIs than children who had good ART adherence. Finally, the chance of experiencing OIs among rural children was 2.15 (95% CI: 1.63, 2.83) times higher than their counterparts in Ethiopia.

Conclusions

Three in every 33 schoolchildren on ART developed OIs in Ethiopia. Predictors of OIs included schoolchildren without parents, those with poor adherence to ART, and rural residents. This suggests that social support, medication adherence, and access to healthcare services may play important roles in preventing and controlling OIs among schoolchildren living with HIV in rural areas.

Incidence and predictors of opportunistic infections among HIV-infected children on antiretroviral therapy at public health facilities of Southwest Ethiopia People Regional State, 2023: a multicenter retrospective follow-up study

BACKGROUND

Opportunistic infections (OIs) pose a significant threat to children infected with HIV. Despite advancements in antiretroviral therapy (ART), these infections continue to be a public health concern. However, there is limited evidence regarding the incidence and predictors of OIs among HIV-infected children in Ethiopia, particularly in the study area. Therefore, the objective of this study was to assess the incidence and predictors of OIs among HIV-infected children on ART at public health facilities of Southwest Ethiopia People Regional State.

METHODS

The study employed an institution-based retrospective cohort design, conducted from July 1, 2018 to July 31, 2023, among HIV-infected children aged less than 15 years. Data were extracted using the national ART intake and follow-up forms. KoboCollect version 2023.2.4 and STATA version 14.0 were used for data collection and analysis, respectively. The Kaplan-Meier survival curve was used to estimate the probability of OI-free survival time. Variables with P-value < 0.25 in the bivariable Cox proportional hazard model were selected as candidates. In multivariable analysis, P-value < 0.05 and adjusted hazard ratio (AHR) with 95% confidence interval (CI) were used to declare statistically significant predictors.

RESULTS

Of the total 409 HIV infected children, 122(29.8%) developed at least one OI, contributing to 954.95 person-years of risk. The overall incidence rate was 12.8 (95% CI: 10.7, 15.2) per 100 person-years. The OI-free survival probability at the end of the follow-up period was 0.277(95% CI: 0.139, 0.434). The commonest OI was pulmonary tuberculosis, 30.33% (95% CI: 22.7, 39.2). Non-disclosing HIV status (AHR: 2.56, 95% CI: 1.42, 4.63), children aged 10-14 years (AHR: 2.34, 95% CI: 1.10, 4.95), no history of prevention of mother-to-child transmission of HIV (AHR: 2.33, 95% CI: 1.48, 3.66), hemoglobin level < 10 mg/dL (AHR: 2.26, 95% CI: 1.37, 3.75), fair or poor adherence to ART (AHR: 1.74, 95% CI: 1.09, 2.79), and having past history of OIs (AHR: 1.61, 95% CI: 1.03, 2.55) were statistically significant predictors of OIs.

CONCLUSION AND RECOMMENDATIONS

The incidence of OIs was high in the study area. Hence, health facilities need to regularly monitor hemoglobin, enhance ART adherence, provide OI prophylaxis for at-risk children, reinforce PMTCT programs for early OI detection and management, and encourage timely and age-appropriate HIV status disclosure. Caregivers of HIV-infected children are also required to oversee and assist their children in adhering to the ART.

Incidence and predictors of common opportunistic infections among children living with HIV at Bahir Dar City, Ethiopia

Despite the dramatic decline in the incidence of common opportunistic infections (OIs) after antiretroviral therapy initiation, they remain a significant cause of morbidity and mortality among children with HIV. For better interventions, information regarding the incidence and predictors of common OIs is essential for Children living with HIV. Still, there is a lack of studies in low and middle-income countries, including Ethiopia. Therefore, this study aims to assess the incidence and predictors of common OIs among Children living with HIV on anti-retroviral therapy (ART) at public health institutions in Bahir Dar City, Northwest Ethiopia. The reasons for excluding children not on ART is we want to study the effectiveness of chronic HIV care service, ART drugs and OIs prophylaxis drugs for the prevention of common OIs because it is obvious that the occurrence of OIs in children not on ART and OIs prophylaxis drugs is high. A health institution-based retrospective cohort study was done among 403 Human Immunodeficiency Virus-infected children at public health institutions in Bahir Dar City from 2010 to 2020. Data was entered using Epi-data version 4.6 and analyzed using STATA 14.0. A bivariable Cox-proportional hazards regression model was employed to appreciate the relationship between each explanatory variable with the outcome variable. In the bivariable analysis, variables with a p-value of less than 0.25 were candidates for the multivariable proportional hazard model. The Cox proportional hazards model was used to determine predictors of common opportunistic infections at a 5% significance level. The overall incidence rate of common opportunistic infections was 7.06 with a 95% confidence interval ((CI) 5.78, 9.75) per 100 person-years of observation. Statically significant predictors were World Health Organization (WHO) clinical stage III and IV (adjusted hazard ratio (AHR) = 1.90; (95% CI 1.34, 2.75), having fair/poor adherence to anti-retroviral therapy (ART) (AHR) = 1.80; (95% CI 1.25, 2.94) and hemoglobin level < 10 g/dl (AHR) = 2.00; (95% CI 1.36, 2.89). The overall incidence rate of common OIs among children living with HIV on ART was high. Independent predictors of common OIs among children on ART were advanced-stage of HIV disease, poor ART adherence, and lower hemoglobin level. Therefore, we recommend strongly working on the prevention of advanced stages of HIV disease and improving poor ART adherence to prevent the incidence of OIs among children living with HIV on ART.

Incidence of loss to follow-up and its predictors among HIV-infected under-five children after initiation of antiretroviral therapy in West Amhara Comprehensive Specialized Referral Hospitals, Northwest Ethiopia: a multicenter retrospective follow-up study

BACKGROUND

Loss to follow-up (LTFU) among under-five children from HIV care profoundly affects the treatment outcomes of this vulnerable population. It is a major factor that negatively affects the benefits of antiretroviral therapy (ART). Current information about LTFU among HIV-positive under-five children on ART is essential for effective treatments. To far, nevertheless, limited research has been done in Ethiopia to address this issue. Thus, this study aimed to assess the incidence and predictors of LTFU among HIV-infected under-five children receiving ART in West Amhara Comprehensive Specialized Referral Hospitals.

METHODS

A multicenter institution-based retrospective follow-up study was conducted among 435 HIV-infected under-five children on ART selected by simple random sampling from January 1, 2010 to December 31, 2019, and data were collected between December 1, 2021, and January 31, 2022. A standardized data extraction tool adapted from the ART entry and follow-up forms was used. The event of interest for this study was LTFU, whereas the absence of LTFU was censored. Before being transferred to STATA version 14 for analysis, the data were entered into Epi-Data version 3.1. The Kaplan‒Meier curve was used to estimate an individual's survival-free probability at each specific point in time. The Cox proportional hazards model was used to identify predictors of LTFU.

RESULTS

Among the 420 records included in the final analysis, 30 (7.14%) of the individuals were LTFUs. The incidence rate of LTFU was 3.4 per 1000 person-months of observation (95% CI: 2.43-4.87). The survival probabilities of children after 12, 24, 36, and 48 months were 0.97, 0.92, 0.88, and 0.77, respectively. The independent predictors of LTFU were HIV infection in under-five children who lived in rural areas (AHR = 3.64; 95% CI: 1.41, 9.37), poor adherence to ART (AHR = 4.37; 95% CI: 1.59, 12.02), not receiving cotrimoxazole preventive therapy (AHR = 3.75; 95% CI: 1.39, 10.08), not receiving isoniazid prophylaxis (AHR = 3.4; 95% CI: 1.29, 9.01), and having a severe WHO clinical stage (AHR = 5.43; 95% CI: 1.38, 11.43).

CONCLUSION AND RECOMMENDATION

The incidence of loss to follow-up was high, especially in the first two years after ART initiation. The risk of LTFU was greater for those who were rural residents, had poor adherence, lacked cotrimoxazole preventive therapy, not given isoniazid prophylaxis, and presented with WHO clinical stages III and IV. Therefore, clinicians should emphasize for cotrimoxazole preventive therapy and isoniazid prophylaxis, for those living in rural areas, who present with poor adherence and WHO clinical stages III and IV.

Predictors for the incidence of pneumonia among HIV-infected children on antiretroviral therapy in Amhara Regional State Comprehensive Specialized Hospitals, Ethiopia: a multicenter retrospective follow-up study

BACKGROUND

Human Immune deficiency Virus (HIV) infected children are at higher risk of developing pneumonia. Particularly, in the early phase of HIV infection, the risk of acquiring pneumonia is high, and it remains a major public health problem even after the test and treatment strategy. There is no clear evidence of the overall incidence of pneumonia among HIV-infected children in Amhara region. Aimed to assess the incidence of pneumonia and its predictors among HIV-infected children receiving Antiretroviral therapy in Amhara Region Comprehensive Specialized Hospitals, 2022.

METHODS

A multicenter retrospective follow-up study was conducted from June 10, 2014, to February 28, 2022, among 430 HIV-positive children receiving antiretroviral therapy. A simple random sampling technique was used. The data was taken from the national antiretroviral intake and follow-up forms. The data were collected via the KoBo toolbox and analyzed using Stata version 17. The Kaplan-Meier curve and log-rank test were employed. Bivariable and multivariable Cox regression was carried out to identify predictors of pneumonia and a P-value < 0.05 was considered significant in to multivariable analysis.

RESULTS

A total of 407 children with a record completeness rate of 94.7% were analyzed in the study. The incidence rate of pneumonia was 4.55 (95% CI; 3.5, 5.92) per 100 person-years observation. The mean survival time was 77.67 months and the total times at risk during follow-up period were yielding 1229.33 person-year observations. Having CD4 cell count below threshold [AHR; 2.71 (95% CI: 1.37, 5.35)], WHO stage III and IV [AHR: 2.17 (95% CI: 1.15, 4.08)], ever had fair and poor treatment adherence [AHR: 2.66 (95% CI: 1.45, 4.89)], and not initiated antiretroviral therapy within seven days [AHR: 2.35 (95% CI: 1.15, 4.78)] were the positive predictors for incidence of Pneumonia.

CONCLUSIONS

In this study, the incidence of pneumonia was lower than the previous studies. CD4 cells below the threshold, ever had fair and poor adherence to antiretroviral therapy, WHO stage III and IV, and not initiated antiretroviral therapy within seven days were significant predictors. Therefore,, it is crucial to detect baseline assessment and give attention to those identified predictors promptly, and timely initiation of antiretroviral therapy need special attention.

Opportunistic Infections in HIV-Infected Children on Treatment in Southern Morocco: A 12-Years Retrospective Follow-up Study

BACKGROUND

Human immunodeficiency virus (HIV) infection in children is a significant public health concern, increasing the risk of infant mortality. Immunodeficiency caused by HIV favors the development of opportunistic infections (OIs), which are responsible for over 90% of HIV-related deaths. This study seeks to determine the primary OIs in children with HIV followed at the Hassan II Regional Hospital Center in Sous Massa, during the period from 2012 to 2023.

MATERIALS AND METHODS

This retrospective study is the first in Morocco to investigate OIs among HIV-infected children. It analyzed 76 complete medical records, using a data collection form designed based on existing literature.

RESULTS

This study revealed that 37% of participants were suffering from OIs, mainly diarrhea (11%), tuberculosis (9%) and pneumonia (7%).There was a significant correlation between OIs and HIV clinical stage (P=0.001), age (P=0.007), and anemia (P=0.001). Despite progress in management, the presence of OIs remains a risk factor for infant morbidity and mortality.

CONCLUSION

The study highlights the importance of early detection, prevention, and adherence to treatment in reducing this burden. Management of anemia is essential.

Proportion of active tuberculosis among HIV-infected children after antiretroviral therapy in Ethiopia: A systematic review and meta-analysis

Despite effectiveness of antiretroviral therapy in reducing mortality of opportunistic infections among HIV infected children, however tuberculosis (TB) remains a significant cause for morbidity and attributed for one in every three deaths. HIV-infected children face disproportionate death risk during co-infection of TB due to their young age and miniatures immunity makes them more vulnerable. In Ethiopia, there is lack of aggregated data TB and HIV mortality in HIV infected children. We conducted an extensive systematic review of literature using Preferred Reporting of Systematic Review and Meta-Analysis (PRISMA) guideline. Five electronic databases were used mainly Scopus, PubMed, Medline, Web of Science, and Google scholar for articles searching. The pooled proportion of TB was estimated using a weighted inverse variance random-effects meta-regression using STATA version-17. Heterogeneity of the articles was evaluated using Cochran's Q test and I2 statistic. Subgroup analysis, sensitivity test, and Egger's regression were conducted for publication bias. This met-analysis is registered in Prospero-CRD42024502038. In the final met-analysis report, 13 out of 1221 articles were included and presented. During screening of 6668 HIV-infected children for active TB occurrence, 834 cases were reported after ART was initiated. The pooled proportion of active TB among HIV infected children was found 12.07% (95% CI: 10.71-13.41). In subgroup analysis, the Oromia region had 15.6% (95%CI: 10.2-20.6) TB burden, followed by southern Ethiopia 12.8% (95%CI: 10.03-15.67). During meta-regression, missed isoniazid Preventive therapy (IPT) (OR: 2.28), missed contrimoxazole preventive therapy (OR: 4.26), WHO stage III&IV (OR: 2.27), and level of Hgb ≤ 10gm/dl (OR = 3.11.7) were predictors for active TB. The systematic review found a higher proportion of active TB in HIV-infected children in Ethiopia compared to estimated rates in end TB strategy. To prevent premature death during co-infection, implement effective TB screening and cases tracing strategies in each follow up is needed.

Incidence and predictors of tuberculosis among HIV-infected children after initiation of antiretroviral therapy in Ethiopia: A systematic review and meta-analysis

BACKGROUND

Globally, Tuberculosis (TB) is the main cause of morbidity and mortality among infectious disease. TB and Human Immune Virus (HIV) are the two deadly pandemics which interconnected each other tragically, and jeopardize the lives of children; particularly in Sub-Saharan Africa. Therefore, this review was aimed to determine the aggregated national pooled incidence of tuberculosis among HIV- infected children and its predictors in Ethiopia.

METHODS

An electronic search engine (HINARI, PubMed, Scopus, web of science), Google scholar and free Google databases were searched to find eligible studies. Quality of the studies was checked using the Joanna Briggs Institute (JBI) quality assessment checklists for cohort studies. Heterogeneity between studies was evaluated using Cochrane Q-test and the I2 statistics.

RESULT

This review revealed that the pooled national incidence of tuberculosis among children with HIV after initiation of ART was 3.63% (95% CI: 2.726-4.532) per 100-person-years observations. Being Anemic, poor and fair ART adherence, advanced WHO clinical staging, missing of cotrimoxazole and isoniazid preventing therapy, low CD4 cell count, and undernutrition were significant predictors of tuberculosis incidence.

CONCLUSION

The study result indicated that the incidence of TB among HIV- infected children is still high. Therefore, parents/guardians should strictly follow and adjust nutritional status of their children to boost immunity, prevent undernutrition and opportunistic infections. Cotrimoxazole and isoniazid preventive therapy need to continually provide for HIV- infected children for the sake of enhancing CD4/immune cells, reduce viral load, and prevent from advanced disease stages. Furthermore, clinicians and parents strictly follow ART adherence.

Incidence rate of tuberculosis among HIV infected children in Ethiopia: systematic review and meta-analysis

BACKGROUND

Tuberculosis is one the leading causes of death from a single infectious disease, caused by the bacillus mycobacterium tuberculosis. In Ethiopia, even though several primary studies have been conducted on the incidence of tuberculosis among HIV-infected children, the pooled incidence rate of tuberculosis among HIV-infected children (aged 0-14 years) is unknown. Therefore, the main objectives of this systematic review and meta-analysis are to estimate the pooled incidence rate of tuberculosis among HIV-infected children and its predictors in Ethiopia.

METHOD

International electronic databases such as PubMed, HINARI, Science Direct, Google Scholar, and African Journals Online were searched using different search engines.  Quality of primary studies was checked using the Joanna Briggs Institute checklist. The heterogeneity of studies was tested using I-square statistics. Publication bias was tested using a funnel plot and Egger's test. Forest plots and tables were used to present the results. The random effect model was used to estimate the pooled incidence of tuberculosis among children living with HIV.

RESULT

A total of 13 studies were included in this systematic review and meta-analysis. The pooled incidence of tuberculosis among HIV-infected children was 3.77 (95% CI: 2.83, 5.02) per 100-person-year observations. Advanced HIV disease (HR: 2.72, 95% CI: 1.9; 3.88), didn't receive complete vaccination (HR: 4.40, 95% CI: 2.16; 8.82), stunting (HR: 2.34, 95% CI: 1.64, 3.33), underweight (HR: 2.30, 95% CI: 1.61; 3.22), didn't receive Isoniazid preventive therapy (HR: 3.64, 95% CI: 2.22, 5.96), anemia (HR: 3.04, 95% CI: 2.34; 3.98), fair or poor antiretroviral therapy adherence (HR: 2.50, 95% CI: 1.84; 3.40) and didn't receive cotrimoxazole preventive therapy (HR: 3.20, 95% CI: 2.26; 4.40) were predictors of tuberculosis coinfection among HIV infected children.

CONCLUSION

This systematic review and meta-analysis concluded that the overall pooled incidence rate of tuberculosis among HIV-infected children was high in Ethiopia as compared to the END TB strategy targets. Therefore, emphasis has to be given to drug adherence (ART and Isoniazid) and nutritional counseling. Moreover, early diagnosis and treatment of malnutrition and anemia are critical to reduce the risk of TB coinfection.

Follow-up for 3 years of a pediatric population diagnosed in 2018 with mother-to-child transmission of HIV in 8 Latin American countries in the PLANTAIDS cohort

INTRODUCTION

The frequency of mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV) in Latin America has decreased considerably. However, new infections continue to be recorded, and the pediatric population remains one of the most vulnerable groups in this region. The main objective of the study was to describe the clinical, epidemiological and psychosocial characteristics of new diagnoses of HIV MTCT in 2018 in the PLANTAIDS network (Paediatric Network for Prevention, Early Detection and Treatment of HIV in Children) during the 3 years following diagnosis.

METHODOLOGY

Retrospective, multicenter, descriptive study based on a 3-year follow-up of patients diagnosed with HIV infection due to MTCT in 2018 in 10 hospitals in 8 Latin American countries (Costa Rica, Ecuador, Mexico, Honduras, El Salvador, Panama, Guatemala and Venezuela). The hospitals belonged to the PLANTAIDS network, which is included in CYTED (Ibero-American Programme of Science and Technology for Development).

RESULTS

The study population comprised 72 pediatric patients (38.9% male). The median age at diagnosis was 2.4 years (IQR: 0.8-5.4). There were 35 cases of opportunistic infections corresponding to 25 patients (34.7%), with tuberculosis being the most common. Adequate childhood vaccination coverage was achieved in 80.5%. There were 3 cases of acute SARS-CoV-2 infection, and these were asymptomatic or mildly symptomatic. According to the Centers for Disease Control and Prevention (CDC) classification, the most frequent clinical-immunological stage at all check-ups was C1. Three patients died from opportunistic infections and/or advanced HIV infection.

CONCLUSIONS

It is important to diagnose HIV infection early in pediatrics, since early initiation of ART is associated with a decrease in mortality. Despite this, HIV infection has a poor prognosis in children, necessitating adequate follow-up to ensure adherence to health care and ART, although it can sometimes prove difficult in children.

Time to develop adverse drug reactions and associated factors among children HIV positive patients on antiretroviral treatment in North West Amhara Specialized Hospitals: Retrospective cohort study, 2022

Introduction

Adverse drug reactions (ADRs) are harmful and unintended reactions to medicines given at standard doses through a proper route of administration for the purpose of prophylaxis, diagnosis, or treatment.

Objective

The objective of this research paper was to assess median time to development of ADRs and associated factors among children HIV positive patients on antiretroviral treatment (ART) in North West Amhara Specialized Hospitals.

Methods

The adverse drug effect survival time was estimated using the Kaplan-Meier survival method and log-rank test curves was applied for analyze "time-to-event" data. Cox regression model was used to identify the associated factors. Adjusted hazard ratios with their respective 95% confidence intervals (CIs) were estimated and a value of p less than 0.05 was used to declare the presence of a significant association.

Result

The overall incidence of ADRs was 0.67 (95% CI: 3.74-4.44) per 10,000 person-year observation, with a median of 57 months. Adults are presenting with opportunistic Infections (OIs) experiences, baseline CD4 < 200 cells/µL counts, 1e, tenofovir disoproxil fumarate-lamivudine-efavirenz ART regimen, bedridden baseline functional status, World Health Organization (WHO) clinical stage II and III were notably associated with the incidence of ADRs development.

Conclusion

ADRs were uncommon in this study. predictors, such as OIs experiences, a low CD4 count, ART regimen, an advanced WHO stage, and bedridden functional status were significantly associated with ADRs.

Predictors associated with CD4 cell count changes over time among HIV-infected children on anti-retroviral therapy follow-up in Mekelle General Hospital, Northern Ethiopia, 2019: a retrospective longitudinal study

INTRODUCTION

AIDS continues to be a serious global public health issue. It targets CD4 cells and immunological cells, which are in charge of the body's resistance against pathogenic pathogens. In situations with limited resources, CD4 cell measurement is essential for assessing treatment responses and clinical judgments in HIV-infected children receiving Anti-Retroviral Therapy (ART). The volatility of CD4 cells during ART follow-up is still largely uncharacterized, and there are few new datasets on CD4 cell changes over time. Therefore, the purpose of this analysis was to identify the factors that were predictive of CD4 cell count changes over time in children who started ART at Mekelle General Hospital in northern Ethiopia.

METHODS

A retrospective follow-up study was done. 437 patients in Mekelle general hospital, northern Ethiopia, from 2014-2016 were involved. All patients who have started anti-retrieval treatment (ART) and measured their CD4 cell count at least twice, including the baseline and those who initiated ART treatment, were included in the study population. An exploratory data analysis and linear mixed model analysis were used to explore the predictors of CD4 cell count change in patients and consider variability within and between patients.

RESULTS

This study found the correlation variation explained in cells accounted for between patients was 61.3%, and the remaining 38.7% variation existed within. This indicates that there is a substantial change in random slope and intercept between and within patients. WHO clinical stage IV (β = -1.30, 95% CI: -2.37, -0.23), co-infection HIV/TB (β = -1.78, 95% CI: -2.58, -0.98), children aged 2-5 (β = -0.43; 95% CI: -0.82, -0.04), and 6-14 years (β = -1.02; 95% CI: -1.47, -0.56), non-opportunistic infection (β = 1.33, 95% CI: 0.51, 2.14), and bedridden functional status (β = -1.74, 95% CI: -2.81, -0.68) were predictors of cell changes over time.

CONCLUSIONS

This study found that patients receiving ART experienced a significant change in CD4 cells over time. Because 61.3% of the variation in CD4 cells explained between patients and the remaining 38.7% within patients, such nested data structures are often strong correlation evidence. Co-infection of HIV/TB, functional status, age category of children, WHO clinical stage, and opportunistic infections are potential predictors of CD4 cells count change. Hence, special guidance and attention is also required, especially for those patients who have an opportunistic infections, higher WHO clinical stages, co-infections with HIV and TB, and bedridden functional status.

Tuberculosis and its associated risk factors among HIV-positive pregnant women in northwest Ethiopia: A retrospective follow-up study

Background

People living with the human immunodeficiency virus have a higher risk of developing active tuberculosis disease. Human immunodeficiency virus infected pregnant women are at a much higher risk of getting active tuberculosis infection, partly due to immune modulation. However, very little is known about the epidemiology of tuberculosis among pregnant women infected with the virus, particularly in resource-limited settings where the burdens of these infections are substantial. Hence, this study aimed to estimate tuberculosis incidence and identify its risk factors among human immunodeficiency virus infected pregnant women in northwest Ethiopia.

Methods

An institutional-based retrospective follow-up study was conducted among pregnant women who were enrolled in option B+ prevention of mother to child transmission service between June 2013 and April 2021 in Pawe district. The Kaplan-Meier survival curve and Weibull regression model were used to estimate survival probability and identify risk factors of tuberculosis, respectively. The best model between the Cox and parametric models was chosen using the Akaike and Bayesian information criteria.

Result

Out of 289 human immunodeficiency virus infected pregnant women included in the final analysis, 29 (10.03 %) developed active tuberculosis. The overall incidence of tuberculosis was 17.4 per 1000 person-months of observation (95 % CI: 12.1, 25.1). Lack of isoniazid preventive therapy (AHR: 6.68, 95 % CI: 2.67, 16.7), new enrollment to care (AHR: 2.62, 95 % CI: 1.14, 6.03), under-nutrition (AHR: 5.09, 95 % CI: 2.02, 12.83), low CD4 count (AHR: 2.61, 95 % CI: 1.01, 6.78), and suboptimal antiretroviral therapy adherence (AHR: 3.17, 95 % CI: 1.46, 6.86) were predictors of tuberculosis among HIV-positive pregnant women.

Conclusion

This study found a high incidence of tuberculosis among human immunodeficiency virus infected pregnant women. Thus, strengthening the provision of tuberculosis preventive therapy, reinforcing adherence support, and controlling under-nutrition should be considered to decrease the risk of tuberculosis.

Incidence and predictors of tuberculosis among children receiving antiretroviral therapy in the Wolaita Zone: A retrospective cohort study

BACKGROUND

Tuberculosis is the leading cause of morbidity and mortality among children living with the human immunodeficiency virus (HIV), mainly in sub-Saharan Africa, including Ethiopia. Tuberculosis remains a significant health concern for HIV-positive children in Ethiopia. There is a paucity of data on the incidence and predictors of tuberculosis among children living with HIV on antiretroviral therapy in the Wolaita zone. Hence, this study aimed to assess the incidence and predictors of tuberculosis among children living with HIV on antiretroviral therapy in the Wolaita zone between January 2010 to December 2020.

METHODS

A retrospective cohort study was conducted among 389 children receiving antiretroviral therapy in Wolaita zone health facilities between January 2010 to December 2020. The checklist was adapted from the standardized antiretroviral treatment (ART) follow-up form currently used by the institutions' ART clinics. The Kaplan-Meier survival function and Log-rank were used to estimate the survival for each categorical variable to compare the survival between different exposure groups. Both bivariable and multivariable parametric survival Gompertz models were fitted to identify predictors of tuberculosis among HIV-positive children. The association was summarized using an adjusted hazard ratio (AHR), and statistical significance was declared at 95% CI and p-value < 0.05. The goodness of the model fit was assessed using a Cox-Snell residual plot.

RESULTS

The incidence rate of tuberculosis among children living with HIV was 3.5 (95% CI 2.7-4.5) per 100 child years. World Health Organization clinical stage III or IV (AHR = 2.31, 95% CI [1.26, 4.22]), hemoglobin level <10 g/dL (AHR = 2.87, 95% CI [1.51, 5.45]), fair or poor ART adherence (AHR = 4.4, 95% CI[2.18, 9.05]), underweight (AHR = 2.55, 95% CI [1.45, 4.51]), age >10 years (AHR = 3.62; 95% CI [1.29, 10.0]), and cotrimoxazole preventive therapy (AHR = 0.23; 95% CI [0.08, 0.60]) were among the independent predictors of TB occurrence.

CONCLUSION

The incidence of tuberculosis among children on ART was high. HIV-positive children presenting with advanced disease staging (III and IV), anemia, "fair" and "poor" ART adherence, underweight, age above ten years, and not receiving cotrimoxazole preventive therapy were at higher risk of TB. Therefore, counseling on ART adherence, early diagnosis, and prompt treatment of anemia and malnutrition are recommended to avert tuberculosis.

The Burden of Pneumocystis Pneumonia Infection among HIV Patients in Ethiopia: A Systematic Review

Pneumocystis pneumonia (PCP) is a leading cause of death among patients with AIDS worldwide, but its burden is difficult to estimate in low- and middle-income countries, including Ethiopia. This systematic review aimed to estimate the pooled prevalence of PCP in Ethiopia, the second most densely populated African country. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were used to review published and unpublished studies conducted in Ethiopia. Studies that reported on the prevalence of PCP among HIV-infected patients were searched systematically. Variations between the studies were assessed by using forest plot and I-squared heterogeneity tests. Subgroup and sensitivity analyses were carried out when I2 > 50. The pooled estimate prevalence with 95% CI was computed using a random-effects model of analysis. Thirteen articles, comprising studies of 4847 individuals living with HIV, were included for analysis. The pooled prevalence of PCP was 5.65% (95% CI [3.74-7.56]) with high heterogeneity (I2 = 93.6%, p < 0.01). To identify the source of heterogeneity, subgroup analyses were conducted by study design, geographical region, diagnosis methods, and year of publication. PCP prevalence differed significantly when biological diagnostic methods were used (32.25%), in studies published before 2010 (32.51%), in cross-sectional studies (8.08%), and in Addis Ababa (14.05%). PCP prevalence differences of 3.25%, 3.07%, 3.23%, and 2.29% were recorded in studies based on clinical records, published since 2017, follow-up studies, and north-west Ethiopian studies, respectively. The prevalence of PCP is probably underestimated, as the reports were mainly based on clinical records. An expansion of biological diagnostic methods could make it possible to estimate the exact burden of PCP in Ethiopia.

Predictors of a high incidence of opportunistic infections among HIV-infected children receiving antiretroviral therapy at Amhara regional state comprehensive specialized hospitals, Ethiopia: A multicenter institution-based retrospective follow-up study

Introduction

Globally, opportunistic infections are the leading causes of morbidity and mortality among HIV-infected children, contributing to more than 90% of HIV-related deaths. In 2014, Ethiopia launched and began to implement a "test and treat" strategy aiming to reduce the burden of opportunistic infections. Despite this intervention, opportunistic infections continue to be a serious public health issue, with limited evidence available on their overall incidence among HIV-infected children in the study area.

Objective

The study aimed to assess the incidence of opportunistic infections and to identify predictors of their occurrence among HIV-infected children receiving antiretroviral therapy at Amhara Regional State Comprehensive Specialized Hospitals in 2022.

Methods

A multicenter, institution-based retrospective follow-up study was conducted among 472 HIV-infected children receiving antiretroviral therapy at Amhara Regional State Comprehensive Specialized Hospitals from May 17 to June 15, 2022. Children receiving antiretroviral therapy were selected using a simple random sampling technique. Data were collected using national antiretroviral intake and follow-up forms via the KoBo Toolbox. STATA 16 was used for data analyses, and the Kaplan-Meier method was used to estimate probabilities of opportunistic infection-free survival. Both bi-variable and multivariable Cox proportional hazard models were employed to identify significant predictors. A P-value <0.05 was taken to indicate statistical significance.

Results

Medical records from a total of 452 children (representing a completeness rate of 95.8%) were included and analyzed in the study. The overall incidence of opportunistic infections among children receiving ART was 8.64 per 100 person-years of observation. The predictors of elevated incidence of opportunistic infections were: a CD4 cell count below a specified threshold [AHR: 2.34 (95% CI: 1.45, 3.76)]; co-morbidity of anemia [AHR: 1.68 (95% CI: 1.06, 2.67)]; ever having exhibited only fair or poor adherence to ART drugs [AHR: 2.31 (95% CI: 1.47, 3.63)]; never having taken tuberculosis-preventive therapy [AHR: 1.95 (95% CI: 1.27, 2.99)]; and not having initiated antiretroviral therapy within 7 days of HIV diagnosis [AHR: 1.82 (95% CI: 1.12, 2.96)].

Conclusion

In this study, the incidence of opportunistic infections was high. Early initiation antiretroviral therapy has direct effect on boosting the immunity, suppressing viral replications and increases the CD4 count, so that the occurrence of opportunistic infection will reduce the incidence of OIs.

Association Between Body Mass Index Variation and Early Mortality Among 834 Ethiopian Adults Living with HIV on ART: A Joint Modelling Approach

INTRODUCTION

Body mass index (BMI) is a simple and cost-effective tool for monitoring the clinical responses of patients living with human immunodeficiency virus (HIV) after antiretroviral therapy (ART) initiation, especially in resource-limited settings where access to laboratory tests are limited. Current evidence on the association between longitudinal BMI variation and clinical outcomes among adults living with HIV receiving ART is essential to inform clinical guidelines. Therefore, this study examines the association between BMI variation and premature mortality in adults living with HIV on ART.

METHODS

An institution-based retrospective cohort study was conducted among 834 adults living with HIV receiving ART from June 2014 to June 2020 at Debre Markos Comprehensive Specialized Hospital in Northwest Ethiopia. We first identified predictors of mortality and BMI variation using proportional hazards regression and linear mixed models, respectively. Then, the two models were combined to form an advanced joint model to examine the effect of longitudinal BMI variation on mortality.

RESULTS

Of the 834 participants, 49 (5.9%) died, with a mortality rate of 4.1 (95% CI 3.1, 5.4) per 100 person-years. A unit increase in BMI after ART initiation corresponded to an 18% reduction in mortality risk. Patients taking tuberculosis preventive therapy (TPT), mild clinical disease stage, and changing ART regimens were at lower risk of death. However, patients with ambulatory/bedridden functional status were at higher risk of death. Regarding BMI variation over time, patients presenting with opportunistic infections (OIs), underweight patients, patients who started a Dolutegravir (DGT)-based ART regimen, and those with severe immunodeficiency had a higher BMI increase over time. However, patients from rural areas and overweight/obese patients experienced a lower BMI increase over time.

CONCLUSION

BMI improvement after ART initiation was strongly associated with a lower mortality risk, regardless of BMI category. This finding implies that BMI may be used as a better predictor tool for death risk in adults living with HIV in Ethiopia. Additionally, patients who took a DGT-based ART regimen had a higher BMI increase rate over time, which aligns with possible positive effects, such as weight gain, of the DGT-based ART regimen in developing countries.

Incidence and predictors of opportunistic infections in adolescents and adults after the initiation of antiretroviral therapy: A 10-year retrospective cohort study in Ethiopia

Background

Opportunistic infections (OIs) are the leading cause of morbidity and mortality in people living with the human immunodeficiency virus (PLHIV). However, there are few robust recent data on the rates of OIs and the risk factors that contribute to their occurrence. Therefore, the current study sought to determine the incidence of OIs and identify predictors among adolescents and adults after the initiation of antiretroviral therapy (ART) at Wolaita Sodo University Comprehensive Specialized Hospital (WSUCSH), Southern Ethiopia.

Methods

A retrospective cohort study design was employed. The study population was adolescents and adults who initiated ART between 1 January 2012 and 31 December 2021. A simple random sampling technique was used to select 537 participants' records. We reviewed the medical records of the sampled individuals from 1 May 2022 to 15 June 2022. KoboCollect version 2021.2.4 and STATA version 14.0 software were used for data collection and analysis, respectively. We calculated the incidence rate per 100 person-years of observation (PYO) with 95% confidence intervals (CIs) for the occurrence of any OIs. The Weibull regression model was fitted after the goodness-of-fit test for the Cox proportional hazard model was deemed inadequate. An adjusted hazard ratio (AHR) with 95% CI was used to identify a significant predictor of OIs. The statistical significance was made at a 5% significance level.

Results

A total of 515 participants contributed to 1,829 person-years of risk, of whom 164 (31.84%) exhibited at least one OI. The overall incidence rate of OIs was 8.97 cases (95% CI: 7.69, 10.44) per 100 PYO. The independent predictors of OIs were being female [AHR: 1.65 (95% CI (1.15, 2.36), P = 0.007)], individuals classified as World Health Organization (WHO) HIV clinical stage III [AHR: 1.98 (95% CI (1.12, 3.51), P = 0.019)], individuals who did not take cotrimoxazole preventive therapy (CPT) [AHR: 2.58 (95% CI (1.62, 4.11), P < 0.001)], mild malnutrition [AHR: 1.62 (95% CI (1.06, 2.54), P = 0.035)], and poor adherence to ART [AHR: 4.21 (95% CI (2.39, 7.44), P < 0.001)].

Conclusion

The rate of OIs after the initiation of ART was still high. Moreover, being female, not taking CPT, poor adherence to ART, mild malnutrition, and advanced HIV disease at presentation were found to increase the hazards of developing OIs.

Survival time and predictors of death among HIV infected under five children after initiation of anti -retroviral therapy in West Amhara Referral Hospitals, Northwest Ethiopia

BACKGROUND

Acquired immune deficiency syndrome is an infectious disease caused by the human immunodeficiency virus (HIV) that primarily targets an individual's immune system. In Ethiopia, nearly 24% of HIV-related deaths occur in children under the age of five. However, studies regarding the survival time of HIV-positive under-five children after anti-retroviral therapy initiation are limited with poor evidence of predictors of death.

OBJECTIVE

To assess survival time and predictors of death among HIV infected under-five children after initiation of anti-retroviral therapy in West Amhara Referral Hospitals, Northwest Ethiopia, 2021.

METHODS

A multicenter institution-based retrospective follow-up study was conducted among 432 HIV-positive under-five children on anti-retroviral therapy selected by simple random sampling from January 2010 to December 2019. A standardized data extraction tool was employed, which was adapted from anti-retroviral therapy entry and follow-up forms. The event of interest for this study is death, whereas the absence of experience of death is censored. Data were entered into Epi-Data version 3.1 and exported to STATA version 14. The Kaplan-Meier curve was used to estimate the survival probability. The Cox regression model was used to identify independent predictors of death.

RESULTS

Among the 415 records included in the final analysis, 25 (6.02%) of the individuals were died. The incidence rate of death was found to be 2.87 per 1000 child-months (95%CI: 1.94-4.25). The cumulative survival probabilities of children after 6, 12, 24, and 36 months were 0.97, 0.95, 0.92, and 0.85 respectively. HIV-infected under-five children who lived in rural areas (AHR 3.32:-95% CI 1.17-9.39), with poor adherence to anti-retroviral therapy (AHR = 3.36; CI: 1.06, 10.69), without Isoniazide prophylaxis (AHR = 3.15; CI: 1.11, 8.94) and with anemia (AHR: 3.05, 95% CI: 1.16, 8.03) were at higher risk of death.

CONCLUSION AND RECOMMENDATION

Death of HIV-infected under-five children on anti-retroviral therapy is high within the first one year after enrolment. Living in rural area, had poor adherence, lacked Isoniazide prophylaxis, and anemia were predictors of death. Therefore, clinicians shall emphasize for those specific risk factors of death and take action accordingly.

HIV positive children living in orphanages and home care: Assessment of nutritional deficiencies and opportunistic infections

Objectives

With the introduction of antiretroviral treatment (ART), opportunistic infections (OIs) reduced a lot and most HIV-associated OIs are preventable and treatable with safe cost-effective interventions. But however, in order to prevent and early diagnosis, we need to have baseline estimation of OIs among HIV positive children and other factors associated, especially nutritional deficiencies.

Methodology

A cross-sectional study was carried out in pediatric outpatient department (OPD) of a large multicentric hospital among 106 children. Data were collected by means of pretested predesigned semi-structed questionnaire prepared on consultation with experts in the subjects and clinical assessment was done in day light to detect signs of nutritional disorders. Institutional ethical clearance was taken, and strict confidentiality was maintained.

Results

Majority (39.6%) of the children belong to 5-9 years. Children were equitably distributed between orphanage and family care giver. Bitot's spots, cheilosis, and gum bleeding were found to be more than twice as common in subjects living with family, as compared to those living in orphanage while aphthous ulcer, knock knee, bow leg were found to be more than twice as common in female subjects as compared males. The prevalence of Pneumonia, Mumps, Herpes zoster, Pulmonary Tuberculosis, Oral candidiasis, and recurrent upper respiratory tract infections (URTI) was found to be about twice as common in subjects living with family, as compared to those living in orphanage while males had more Chicken pox, Herpes zoster, Pulmonary Tuberculosis, Oral candidiasis, and Recurrent URTI as compared to those in females.

Conclusion

Vitamin deficiencies and opportunistic infections were higher than the prevalence reported by the various studies done on normal children. All efforts to be made to improve adequate nutrition to HIV positive children and ensure protection against opportunistic infections especially for children in home-based care.

Immuno-virological status and its associated factors among HIV-positive patients receiving highly active antiretroviral therapy at delgi primary hospital, northwest Ethiopia, 2020/2021: A cross-sectional study

Background

Highly active antiretroviral therapy (HAART) improves clinical outcomes by suppressing viral replication and allowing immune reconstitution. It also reduces HIV-related complications including morbidity, mortality, and extended hospitalizations for HIV-positive individuals. Regular assessment for antiretroviral treatment response is fundamentally important to address the factors associated with the poor clinical outcome including immunologic failures among HIV-positive patients on HAART. Therefore, this study aimed to investigate the immuno-virological status and describe its determinants among HIV-positive patients receiving HAART at Delgi primary hospital, Northwest Ethiopia.

Methods

A hospital-based cross-sectional study was conducted at Delgi primary hospital from October 25th through June 19th 2021 among a total of 442 study participants. A systematic random sampling technique was employed to enrol participants in the study. Socio-demographic and clinically related data were collected using a semi-structured questionnaire. About 3–5 ml of venous blood was collected aseptically for CD4⁺ T cell count and viral load test. SPSS version 20 software was used for statistical analysis. Bivariate and multivariate logistic regression analyses were conducted to determine the factors associated with immuno-virologic status among HIV-positive patients on HAART. The odds ratio with 95% CI was computed to determine the strength of association. Then, a p-value < 0.05 was considered a statistically significant association. For this study, the results were presented by using frequency summary tables, and texts.

Results

Among the total study participants, 283 (64%) were males and the mean age of the study participants was 37 ± 11.5. The overall immunological and virological failure among highly active antiretroviral therapy (HAART) receiving participants was found to be 9.5% (42/442, 95%CI:3.23–15.09) and 12.2% (54/442, 95% CI: 2.81–23.04) respectively. In the multivariate analysis, study participants with age ≥50 years old [AOR = 1.97, p = 0.01, 95%CI (0.02–4.03)], participants having current viral load count greater ≥1000 copies/ml [AOR = 3.97, p = 0.03, 95%CI (1.09–5.01)] and having TB-co-infection [AOR = 2.51, p = 0.05, 95%CI (1.02–7.51)] were statistically associated with increased risk of immunological failure. Similarly, TB-coinfected participants were 1.88 (95%CI = 0.89–10.02) times at greater risk for virological failure.

Conclusion

In this study, the magnitude of immuno-virological failure is alarming. This may be shown the need for integrated and substantial commitment to enhancing patient antiretroviral treatment adherence in the study area. Also, regular assessment for antiretroviral treatment response is fundamentally important to address the determinants associated with virological and immunologic failures among HIV-positive patients taking HAART. Furthermore, early initiation of HAART may be imperative to achieve favourable virological suppression and immunological reconstitution.

Time to occurrence, predictors, and patterns of opportunistic infections incidence among HIV-positive patients attending Antiretroviral Therapy Clinic of Salale University Comprehensive Specialized Hospital: A retrospective cohort study

Opportunistic infections (OIs) in HIV patients are infections that are more common or more severe as a result of HIV-mediated immunosuppression. The advances in the capacity of antiretroviral therapy (ART) have diminished the incidence of OIs. However, even in the ART era, HIV-related OIs continue to be major causes of hospitalization and mortality. Therefore, this study aims to identify time to occurrence, predictors, and patterns of OIs incidence among HIV-positive patients attending ART clinic of Salale University Comprehensive Specialized Hospital, Ethiopia. A retrospective cohort study was conducted between 1st September 2016 and 1st September 2021. All 419 patients diagnosed during the study period were recruited. Data were extracted from both patient medical records and ART logbooks. Stata-16 was used for data analysis. Follow-up time was calculated from the date of HIV diagnosis to the date of OIs occurrence or censoring. Cox proportional hazards regression model was used to identify the predictors of OIs incidence. The total person-time of the follow-up was 8656 person-months of observation. During the follow-up time, 199 (47.49%) of the patients had developed OIs. The incidence rate of OIs was 23 (95%CI: 20, 26) per 1000 person-months of observation. The median OIs free survival time was 36 (95%CI: 31, 40) months. Predictors such as residence, cd4 category, baseline hemoglobin level, ART side effects, isoniazid preventive therapy, and chronic disease comorbidity were significantly predicted OIs incidence. The study area's OIs incidence remained high, requiring prompt action. To reduce the morbidity and mortality associated with OIs, HIV-positive patients with the predictors of rural residence, low CD4 category, low baseline hemoglobin level, ART side effects, not taking IPT, and baseline chronic disease comorbidity necessitate close follow-up and monitoring. Thus, we recommend focused and evidence-informed strategies to address OIs burden and improve outcomes.

Severe Recurrent Bacterial Pneumonia Among Children Living With HIV

BACKGROUND

Bacterial pneumonia imparts a major morbidity and mortality burden on children living with HIV, yet effective prevention and treatment options are underutilized. We explored clinical factors associated with severe recurrent bacterial pneumonia among children living with HIV.

METHODS

Children enrolled in the TREAT Asia Pediatric HIV Observational Database were included if they started antiretroviral therapy (ART) on or after January 1st, 2008. Factors associated with severe recurrent bacterial pneumonia were assessed using competing-risk regression.

RESULTS

A total of 3,944 children were included in the analysis; 136 cases of severe recurrent bacterial pneumonia were reported at a rate of 6.5 [95% confidence interval (CI): 5.5-7.7] events per 1,000 patient-years. Clinical factors associated with severe recurrent bacterial pneumonia were younger age [adjusted subdistribution hazard ratio (aHR): 4.4 for <5 years versus ≥10 years, 95% CI: 2.2-8.4, P < 0.001], lower weight-for-age z-score (aHR: 1.5 for <-3.0 versus >-2.0, 95% CI: 1.1-2.3, P = 0.024), pre-ART diagnosis of severe recurrent bacterial pneumonia (aHR: 4.0 versus no pre-ART diagnosis, 95% CI: 2.7-5.8, P < 0.001), past diagnosis of symptomatic lymphoid interstitial pneumonitis or chronic HIV-associated lung disease, including bronchiectasis (aHR: 4.8 versus no past diagnosis, 95% CI: 2.8-8.4, P < 0.001), low CD4% (aHR: 3.5 for <10% versus ≥25%, 95% CI: 1.9-6.4, P < 0.001) and detectable HIV viral load (aHR: 2.6 versus undetectable, 95% CI: 1.2-5.9, P = 0.018).

CONCLUSIONS

Children <10-years-old and those with low weight-for-age, a history of respiratory illness, low CD4% or poorly controlled HIV are likely to gain the greatest benefit from targeted prevention and treatment programs to reduce the burden of bacterial pneumonia in children living with HIV.

Incidence of Pneumonia and Predictors Among Human Immunodeficiency Virus Infected Children at Public Health Institutions in the Northwest Part of Ethiopia: Multicenter Retrospective Follow-Up Study

Introduction

Pneumonia is an inflammation of the lung parenchymal structure secondary to hematogens spread of pathogens, inhalation, or aspiration. It is also one of the most frequently occurring opportunistic infections in HIV-infected children. In Ethiopia, data on the incidence and predictors of opportunistic infection, especially pneumonia, among HIV-infected children is very limited. Hence, this study aimed to assess the incidence of pneumonia and predictors among HIV-infected children at public health institutions in the Northwest part of Ethiopia.

Methods

An institution-based retrospective cohort study was conducted among 342 HIV-infected children at public health institutions from January 1, 2013 to December 30, 2020. Log rank test was used to compare the survival curves between different explanatory variables. Bivariable Cox proportional hazards regression model was employed for each explanatory variable to check the association with the outcome variable. Variables found to have a p-value of < 0.25 in the bivariable analysis were candidates for the multi-variable proportional hazard model. Cox proportional hazards model was used at 5% level of significance to identify predictors of pneumonia.

Results

This study included 342 records of HIV-infected children who started antiretroviral therapy between the periods of January 1, 2013 to December 30, 2020. The overall incidence rate of pneumonia during the follow-up time was 5.57 (95% CI: 4.4, 7.0) per 100 child-years of observation. Those children who did not take cotrimoxazole preventive therapy (AHR: 3, 95% CI: 1.40, 6.44), being underweight at baseline (AHR: 2.6, 95% CI: 1.41, 4.86), having baseline advanced disease (clinical stages III and IV) (AHR: 2.8, 95% CI: 1.30, 6.04), and presenting with recently detected viral load (AHR: 5.9, 95% CI: 2.53, 14.06), were more likely to develop pneumonia.

Conclusion

Pneumonia incidence rate was high. Providing prophylaxis and nutritional supplementation for those children with baseline advanced disease stage, low weight for age and detectable viral load would reduce pneumonia occurrence.

The demographic and clinical characteristics of women living with HIV and the opportunistic infections they experience in Manokwari Regency, West Papua

The number of women living with HIV (WLHIV) in Indonesia, especially Papua, is increasing yearly, along with the increasing number of men who transmit HIV to their partners. WLHIV are susceptible to opportunistic infections, leading to increased morbidity and mortality. This study, aiming to identify the characteristics and opportunistic infections among WLHIV in Manokwari Regency, West Papua, was descriptive with a cross-sectional study design involving 70 WLHIV who routinely received antiretroviral treatment at the VCT of RSUD Manokwari as respondent. Data on demographic and clinical variables were obtained through interviews using structured questionnaires. Data were analyzed by fisher exact tests to measure the association of opportunistic infections with demographic and clinical variables. The results showed that the demographic characteristics of WLHIV: aged18-35 years (47.1%), high school education (42.9%), private employment (47.1%), married (65.7%), ethnic Papuan (65.7%), and heterosexual risk factor (97.1%). Meanwhile, their clinical characteristics were clinical stage III (62.9%), CD4+ ≥350 cell/mm3 (62,9%), detectable viral load (55,7%), and underweight (38.6%). The most opportunistic infections among them were pulmonary tuberculosis (58.6%). The clinical stage of HIV and CD4+ cells was significantly associated with opportunistic infections among WLHIV. For these reasons, it is necessary to intervene by applying antiretroviral administration strategies and specific antimicrobial therapy.

Levels of Adherence and Associated Factors Among Children on ART Over Time in Northwest, Ethiopia: Evidence from a Multicenter Follow-Up Study

Background

Despite the increased availability of antiretroviral therapy (ART), its success depends on a high level of adherence to a life-long antiretroviral therapy. However, the extent and factors associated with adherence to ART are not well known, especially in the current study setup. Therefore, this study aimed to assess the level of adherence and associated factors among children on ART in Northwest, Ethiopia.

Methods

A retrospective follow-up study was conducted on human immunodeficiency virus (HIV)-infected children receiving ART at South Gondar public hospitals. Children receiving ART from January 1, 2015, to November 30, 2020, were included in the study. A computer-generated simple random sampling technique was employed. The data were entered into the EpiData version 3.1 and analyzed by STATA 14 statistical software. Bivariable logistic regression was fitted for each predictor variable. Moreover, those variables having a p-value ≤0.25 in bivariate analysis were fitted into a multivariable logistic regression model. P-value <0.05 was used to declare significance.

Results

A total of 363 HIV-infected children were involved in the study. From 363 HIV-infected children, the level of adherence to ART was found to be 78.2%, 95% CI (73.6, 82.2). TB co-infection [adjusted odds ratio (AOR) = 3.8, 95% CI (1.41, 10.1)], short duration on ART (AOR = 3.4, 95% CI (1.60, 7.20)), treatment failure (AOR = 10.2, 95% CI (3.95, 26.2)), and Zidovudine containing ART regimen (AOR = 3.5, 95% CI (1.1, 10.9)) were significant predictors of poor adherence.

Conclusion

The current study showed that the level of adherence to ART was found to be low TB co-infection, short duration of ART, Zidovudine-containing ART regimen, and treatment failure were found to be significantly associated with poor adherence. Further studies on adherence rate and its determinants with multiple adherence measurements using prospective and multicenter studies were recommended.

Different Trends of Distinct Time Points of AIDS Events Following HIV Diagnosis in Various At-risk Populations: A Retrospective Nationwide Cohort Study in Taiwan

Introduction

Acquired immune deficiency syndrome (AIDS) events at distinct time points after human immunodeficiency virus (HIV) diagnosis require various AIDS prevention strategies. However, no nationwide epidemiological surveillance studies have been conducted to explore the trends of distinct AIDS event time points in various at-risk populations. The aim of this study was to explore the issues and characterize the determinants of AIDS status after HIV diagnosis.

Methods

This nationwide cohort study enrolled HIV-positive Taiwanese during 1984–2016. AIDS events were classified into three time points (≤ 3, 4–12, > 12 months) by their occurrence time after HIV diagnosis. The periods of HIV/AIDS diagnosis were divided into six categories according to the calendar year of HIV/AIDS diagnosis: 1984–1991, 1992–1996, 1997–2001, 2002–2006, 2007–2011, and 2012–2016. HIV-positive Taiwanese during 1984–2011 were then selected to determine the factors associated with four AIDS statuses within 5 years after HIV diagnosis (no AIDS, AIDS ≤ 3 months, within 4–12 months, > 12 months) using multinomial logistic regression.

Results

Of 33,142 cases, we identified 15,254 (46%) AIDS events. The overall AIDS incidence (events/100 person-years) peaked during 1992–1996 (20.61), then declined, and finally stabilized from 2002 (8.96–9.82). The evolution of the proportion of distinct time points of AIDS events following HIV diagnosis changed significantly in heterosexuals and intravenous drug users (IDUs) during 1984–2016 (decline at ≤ 3 months in IDUs, decline at 4–12 months in IDUs, and increase at > 12 months in heterosexuals and IDUs) but not among men who have sex with men (MSM). Time points at ≤ 3 months remained at > 50% among MSM and at > 55% among heterosexuals. In multinomial logistic regression, IDUs (vs. men who have sex with men; MSM) had a lower risk of all AIDS statuses; heterosexuals (vs. MSM) had a higher risk of AIDS events ≤ 3 months after HIV diagnosis.

Conclusion

The magnitude of AIDS in Taiwan has been stable since 2002. Enhancing early diagnosis among people with sexual contact and optimizing the HIV care continuum among heterosexuals and IDUs should be priorities for further AIDS prevention strategies.

Incidence of advanced opportunistic infection and its predictors among HIV infected children at Debre Tabor referral Hospital and University of Gondar Compressive specialized hospitals, Northwest Ethiopia, 2020: A multicenter retrospective follow-up study

Background

This study is aimed to assess the incidence of advanced opportunistic infections (OIs) and its predictors among Human Immunodeficiency Virus (HIV) infected children at Debre Tabor referral Hospital and University of Gondar Compressive specialized Hospitals, Northwest Ethiopia, 2020.

Methods

A retrospective follow-up study was conducted from June 1, 2010, to May 30, 2020. A total of 349 children under the age of 15 who had received Anti-Retroviral Therapy (ART) were included in the study. Data were entered into Epi info version 7.2 and then exported to Stata 14.0 for analysis. Kaplan Meier curve and Log-rank test were used to determine the median survival time and the discrepancy of different categorical variables. The Cox regression model was used to identify the predictors of advanced opportunistic infections. The Adjusted hazard ratio (AHR) at 95% confidence interval (CI) was used to declare statistical significance.

Result

The incidence rate of advanced opportunistic infection was 5.53 per 100 (95% CI: 4.7, 6.9) Person per year observation (PYO). The median survival time was 113 months and the total follow-up periods were yielding 18882 months. Children presenting with treatment failure, Cotrimoxazole Preventive Therapy (CPT) non-user, low hemoglobin level (<10 mg/dl), and poor/fair level of adherence to ART were less free survival time as compared to their counterparts for advanced opportunistic infections.

Conclusion

In this study, the median of advanced OIs free survival time was found to be low and the incidence rate was found to be high. The incidence advanced OIs was associated with anemia, treatment failure, and poor/fair level of adherence, cotrimoxazole preventive therapy non-users. Further research should conduct to evaluate and to improve the quality of care in the study area.

Time to detection of anemia and its predictors among children living with HIV at Debre Tabor and University of Gondar Compressive Specialized Hospitals, 2020: a multicentre retrospective follow-up study

BACKGROUND

Even though antiretroviral therapy access for HIV infected children increased dramatically, anemia have been continued as a challenge regardless of a cluster of differentiation (CD4) count and viral load. Hence, this study aimed to assess the time to detection of anemia and its predictors among children living with HIV at Debre Tabor and university of Gondar compressive specialized hospital, 2020.

METHODS

A retrospective follow-up study was conducted from January 2010 to December 2018. A total of 372 children under the age of 15 who had received ART were included in the study. Data were collected from children's medical charts and ART registration logbook using a standard checklist. Besides, the data were entered into Epi data 4.2.2 and then exported to Stata 14.0 for further analysis. The Cox regression model, the variables having P-value ≤.05 with 95% CIs in multivariable analysis were declared as statistically significant for anemia.

RESULT

The mean (±SD) of follow-up periods were 56.6 ± 1.7 SD months. The overall median survival time free from anemia was 137 months, and the incidence rate of anemia was 6.9 per 100 PYO (95% CI: 5.3, 7.8). Moreover, WHO clinical staging of III/IV [AHR: 4.2, 95% CI: 1.80, 11.1], low CD4 count below threshold [AHR: 1.9, 95% CI: 1.09, 3.37], cotrimoxazole preventive therapy non-users, and poor level of adherence [(AHR: 2.4, 95% CI: 1.20, 4.85] were the main predictors of the time to detection of anemia.

CONCLUSION

The incidence rate of anemia in our retrospective cohort was high. The risk of anemia is present in children living with HIV infection but the risk for anemia is increased based on (WHO clinical staging III and IV, CD4 count below the threshold level, CPT non-users, and poor level of adherence). Since many of these risk factors are present routinely, even within one single patient, our clinical monitoring for anemia quarterly was fully justified as was our routine switch from standard therapies such as AZT to another regimen upon lab confirmation of anemia. Additional methods to improve cotrimoxazole preventative therapy and level of adherence are also needed.

Biofilm-Producing Candida Species Causing Oropharyngeal Candidiasis in HIV Patients Attending Sukraraj Tropical and Infectious Diseases Hospital in Kathmandu, Nepal

Introduction

Oropharyngeal candidiasis are the commonest fungal infections among HIV-positive patients. The main objective of this study was to explore biofilm-producing Candida species causing oropharyngeal infections among HIV patients attending Sukraraj Tropical and Infectious Diseases Hospital (STIDH) in Kathmandu, Nepal.

Methods

Oropharyngeal swabs were collected from the HIV-positive patients between July and December 2019. A total of 174 oropharyngeal swabs were cultured on Sabouraud Dextrose Agar (SDA). All samples were inoculated on SDA slants supplemented with chloramphenicol and underwent incubation at 37°C for 24-48 hours. Any visible growth reported was processed for the identification of the species. Candida species were differentiated based on the growth and colour of the isolates on CHROM agar candida. Biofilm production in Candida species was determined by the microtiter plate method (MPM). Antifungal susceptibility testing was performed using the disc diffusion method.

Results

Among 174 oropharyngeal samples, 23.6% (n=41/174) of them had oropharyngeal infections and 36.6% of the oropharyngeal infections (15/41) had CD4 T-lymphocytes count below 200 cells/mm³ who were also active tobacco users (p<0.05). Among Candidial growth, 61% (25/41) were Candida albicans and 39% (16/41) were non-albicans. Of 41 Candida spp., 65% (27/41) were biofilm producers. An equal proportion of Candida albicans (4 isolates) and non-albicans (4 isolates) were strong biofilm producers. C. albicans isolates were sensitive towards clotrimazole (96%; 24/25) and fluconazole (92%; 23/25), whereas sensitivity towards ketoconazole was only 48% (12/25). Non-albicans Candida was highly sensitive to amphotericin-B (62.5%; 10/16) followed by clotrimazole (56.2%; 9/16). The biofilm-producing Candida isolates showed the highest resistivity (51.9%; 14/27) to ketoconazole and lowest (22.2%; 6/27) to clotrimazole.

Conclusion

Oropharyngeal candidiasis is a common opportunistic infection among HIV-infected individuals. The majority of cases of oropharyngeal candidiasis are caused by biofilm producers Candida albicans and non-albicans Candida. Biofilm producers Candida were more resistant towards commonly used antifungal drugs.
