Risk Factors for Mortality among Adult HIV/AIDS Patients Following Antiretroviral Therapy in Southwestern Ethiopia: An Assessment through Survival Models

The estimation of long and short term survival time and associated factors of HIV patients using mixture cure rate models

BACKGROUND

HIV is one of the deadliest epidemics and one of the most critical global public health issues. Some are susceptible to die among people living with HIV and some survive longer. The aim of the present study is to use mixture cure models to estimate factors affecting short- and long-term survival of HIV patients.

METHODS

The total sample size was 2170 HIV-infected people referred to the disease counseling centers in Kermanshah Province, in the west of Iran, from 1998 to 2019. A Semiparametric PH mixture cure model and a mixture cure frailty model were fitted to the data. Also, a comparison between these two models was performed.

RESULTS

Based on the results of the mixture cure frailty model, antiretroviral therapy, tuberculosis infection, history of imprisonment, and mode of HIV transmission influenced short-term survival time (p-value < 0.05). On the other hand, prison history, antiretroviral therapy, mode of HIV transmission, age, marital status, gender, and education were significantly associated with long-term survival (p-value < 0.05). The concordance criteria (K-index) value for the mixture cure frailty model was 0.65 whereas for the semiparametric PH mixture cure model was 0.62.

CONCLUSION

This study showed that the frailty mixture cure models is more suitable in the situation where the studied population consisted of two groups, susceptible and non-susceptible to the event of death. The people with a prison history, who received ART treatment, and contracted HIV through injection drug users survive longer. Health professionals should pay more attention to these findings in HIV prevention and treatment.

Joint Modeling of Longitudinal Outcome and Competing Risks: Application to HIV/AIDS Data

BACKGROUND

Tuberculosis (TB) and human immunodeficiency virus (HIV) are major public health challenges globally, and the number of TB infections and death caused by HIV are high because of HIV/ TB co-infection. On the other hand, CD4 count plays a significant role in TB/HIV co-infections. We used a joint model of longitudinal outcomes and competing risks to identify the potential risk factors and the effect of CD4 cells on TB infection and death caused by HIV in HIV-infected patients.

STUDY DESIGN

This was a retrospective cohort study.

METHODS

The current study was performed on 1436 HIV+patients referred to Behavioral Diseases Counseling Centers in Kermanshah Province during 1998-2019. In this study, joint modeling was used to identify the effect of potential risk factors and CD4 cells on TB and death caused by HIV.

RESULTS

The results demonstrated that the decreasing CD4 cell count was significantly associated with an increased risk of death, while it had no significant relation with the risk of TB. In addition, patients with TB were at a higher risk of death. Based on the results, a significant relationship was found between CD4 count and sex, marital status, education level, antiretroviral therapy (ART), time, and the interaction between time and ART. Further, people infected with HIV through sexual relationships were at higher risk of TB, while those with a history of imprisonment who received ART or were infected with HIV through drug injection had a lower risk of TB.

CONCLUSION

The findings revealed that the decreasing CD4 count had a significant association with an increased risk of death caused by HIV. However, it was not significantly related to the risk of TB. Finally, patients with TB were at higher risk of death caused by HIV.

Survival analysis and predictors of mortality among adult HIV/AIDS patients initiated antiretroviral therapy from 2010 to 2015 in Dubti General Hospital, Afar, Ethiopia: A retrospective cohort study

Background

Although antiretroviral therapy (ART) is well accepted to increase survival of patients with HIV/AIDS, AIDS related deaths continue to be a major problem in sub-Saharan Africa like Ethiopia. Studies have showed variable findings in the survival status of patients with HIV/AIDS initiating ART, and there was no such study in the study area. Therefore, purpose of this study was to determine the survival and predictors of mortality among HIV/AIDS patients starting taking ART in Dubti General Hospital, Afar, Ethiopia.

Methods

A 5 year retrospective cohort study was performed among 702 HIV/AIDS patients aged ≥15 years that started ART between December 31, 2010, and December 31, 2015 in Dubti General Hospital, Afar, Ethiopia. A simple random sampling technique was used to select the study subjects from each WHO stage based stratum. Socio-demographic, clinical and survival status data were extracted by reviewing patients' records. Data were analyzed by using SPSS Version 21. Kaplan-Meier and Cox-regression models were used to estimate survival, and explore predictors of mortality. Variables with a p value of <0.05 in multivariate Cox regression analysis were considered statistically significant.

Results

Among 702 study participants, 82 (11.7%) died during follow up, and the overall incidence rate of mortality was 5.81 per 100 person-years. Identified predictors of mortality were being not married (AHR = 3.71, 95% CI: 1.97-6.99), had no formal education (AHR = 2.33, 95% CI: 1.33-4.38), bedridden functional status (AHR = 5.91, 95% CI: 2.71-12.88), advanced WHO stage III and IV (AHR = 4.36, 95% CI: 2.20-8.64), BMI 16-18.4 kg/m² (AHR = 3.03, 95% CI: 1.50-6.13), and BMI<16.0 kg/m² (AHR = 5.47; 95% CI: 2.85-10.50), CD4 count ≤50 cells/mm³ (AHR = 6.62, 95% CI: 4.73-8.52), hemoglobin <8 g/dl (AHR = 5.21; 95% CI: 2.64-10.26), not used cotrimoxazole prophylaxis therapy (AHR = 2.78, 95% CI: 1.61-4.73), stavudine based regimen (AHR = 2.34, 95% CI: 1.32-4.13), and zidovudine based regimen (AHR = 2.49, 95% CI: 1.41-4.39).

Conclusion

High mortality was observed in this cohort, and participants with stage III and IV, low CD4 count, low hemoglobin level, bed ridden functional status, low BMI should be closely monitored even with the scarce resources. In addition, the use of cotrimoxazole prophylaxis therapy should be more encouraged to increase survival.

Construction and validation of a prognostic nomogram for predicting the survival of HIV/AIDS adults who received antiretroviral therapy: a cohort between 2003 and 2019 in Nanjing

BACKGROUND

Great achievements have been achieved by free antiretroviral therapy (ART). A rapid and accurate prediction of survival in people living with HIV/AIDS (PLHIV) is needed for effective management. We aimed to establish an effective prognostic model to forecast the survival of PLHIV after ART.

METHODS

The participants were enrolled from a follow-up cohort over 2003-2019 in Nanjing AIDS Prevention and Control Information System. A nested case-control study was employed with HIV-related death, and a propensity-score matching (PSM) approach was applied in a ratio of 1:4 to allocate the patients. Univariable and multivariable Cox proportional hazards analyses were performed based on the training set to determine the risk factors. The discrimination was qualified using the area under the curve (AUC) and concordance index (C-Index). The nomogram was calibrated using the calibration curve. The clinical benefit of prognostic nomogram was assessed by decision curve analysis (DCA).

RESULTS

Predictive factors including CD4 cell count (CD4), body mass index (BMI) and hemoglobin (HB) were determined and incorporated into the nomogram. In the training set, AUC and C-index (95% CI) were 0.831 and 0.798 (0.758, 0.839), respectively. The validation set revealed a good discrimination with an AUC of 0.802 and a C-index (95% CI) of 0.786 (0.681, 0.892). The calibration curve also exhibited a high consistency in the predictive power (especially in the first 3 years after ART initiation) of the nomogram. Moreover, DCA demonstrated that the nomogram was clinically beneficial.

CONCLUSION

The nomogram is effective and accurate in forecasting the survival of PLHIV, and beneficial for medical workers in health administration.

Statistical Analysis on Determinant Factors Associated with Time to Death of HIV/TB Co-Infected Patients Under HAART at Debre Tabor Referral Hospital: An Application of Accelerated Failure Time-Shared Frailty Models

Background

Human immune virus/tuberculosis co-infection in one's immune system potentiates each other and hastening the weakening of the host's immunological capabilities while growing active TB, which will increase susceptibility to primary contamination, re-contamination, and/or reactivation for sufferers with latent TB. The goal of this study was to identify determinant factors associated with the survival time to death of HIV/TB co-infected adult patients under HAART at Debre Tabor referral hospital.

Methods

A retrospective follow-up analysis was undertaken for 243 HIV/TB co-infected patients who were receiving ART treatment and had follow-ups between January 2014 and December 2019. To compare the survival experiences of different patient groups, the Log rank test was performed. The Weibull accelerated failure time gamma shared frailty model was used to find determinants of HIV/TB co-infected patients' survival time.

Results

Among HIV/TB co-infected patients, 87 (35.39%) died of whom 77 (88.5%) patients were females. The Weibull AFT gamma shared frailty model showed that sex, baseline age, adherence status, educational status of respondents, functional status, WHO clinical stage, baseline hemoglobin and type of TB were among the potential determinants of survival time of HIV/TB co-infected patients. Furthermore, the findings of this study demonstrated that there is a clustering impact on patient time to death that results from the residency of HIV/TB co-infected patients' survival time.

Conclusion and Recommendation

The majority of patients reside in rural area, have poor adherence to treatment, and have low CD4 cell counts. Educational status, WHO clinical stages, adherence status, and hemoglobin levels of patients are all important determinants of HIV/TB co-infected patients' survival. As a result, to improve the survival of HIV/TB co-infected patients at the start of and during some stages of anti-TB treatment, the concerned body, FMOH, in collaboration with Regional Health Bureau, should emphasize the importance of following treatment for HIV/TB co-infected patients with poor adherence status, advanced WHO clinical stages, and a low CD4+ count.

Predictors of Mortality Among Adult HIV-Infected Patients Taking Antiretroviral Therapy (ART) in Harari Hospitals, Ethiopia

Introduction

Despite the world has made efforts, the reduction of acquired immunodeficiency syndrome (AIDS) related mortality by giving antiretroviral therapy (ART), still HIV/AIDS is killing people while they are on ART. However, the current progress and associated factors of mortality among ART-taking patients are hardly available. Therefore, this study was aimed to determine predictors of mortality among HIV-infected adult patients after starting antiretroviral therapy in Harar Hospitals, Harari region, Ethiopia.

Methods

A facility-based retrospective cohort study was employed with randomly selected 610 medical records of HIV patients on antiretroviral therapy (ART). Adjusted hazard ratio (AHR) with 95% confidence interval (CI) was used to identify predictors of mortality using multivariate Cox proportional hazard model.

Results

Among 610 medical records analyzed with a total of 1410.7 follow-up years, 67 (11%) deaths were found giving an overall mortality rate of 4.75 per 100 person-years. The independent predictor of mortality identified was ambulatory/bedridden functional status (AHR=2.48; 95% CI: 1.43-4.28), taking other than Tenofovir-based regimen (AHR=2.5,95% CI; 1.04-5.94), not taking isoniazid preventive therapy (IPT) (AHR=2.8; 95% CI: 1.61,4.71), hemoglobin <11g/dl (AHR=3.33,95% CI 1.94-5.69), and poor adherence to ART (AHR= 3.62, 95% CI: 1.87-7.0).

Conclusion

This study demonstrated that poor ART adherence, not taking IPT, and initiating ART with a non-Tenofovir-based regimen and low hemoglobin count were significantly associated with the risk of death. For this reason, addressing these all significant predictors is essential to prevent early death.

High HIV prevalence among decedents received by two high-volume mortuaries in Kisumu, western Kenya, 2019

Background

Accurate data on HIV-related mortality are necessary to evaluate the impact of HIV interventions. In low- and middle-income countries (LMIC), mortality data obtained through civil registration are often of poor quality. Though not commonly conducted, mortuary surveillance is a potential complementary source of data on HIV-associated mortality.

Methods

During April-July 2019, we assessed HIV prevalence, the attributable fraction among the exposed, and the population attributable fraction among decedents received by two high-volume mortuaries in Kisumu County, Kenya, where HIV prevalence in the adult population was estimated at 18% in 2019 with high ART coverage (76%). Stillbirths were excluded. The two mortuaries receive 70% of deaths notified to the Kisumu East civil death registry; this registry captures 45% of deaths notified in Kisumu County. We conducted hospital chart reviews to determine the HIV status of decedents. Decedents without documented HIV status, including those dead on arrival, were tested using HIV antibody tests or polymerase chain reaction (PCR) consistent with national HIV testing guidelines. Decedents aged less than 15 years were defined as children. We estimated annual county deaths by applying weights that incorporated the study period, coverage of deaths, and mortality rates observed in the study.

Results

The two mortuaries received a total of 1,004 decedents during the study period, of which 95.1% (955/1004) were available for study; 89.1% (851/955) of available decedents were enrolled of whom 99.4% (846/851) had their HIV status available from medical records and post-mortem testing. The overall population-based, age- and sex-adjusted mortality rate was 12.4 per 1,000 population. The unadjusted HIV prevalence among decedents was 28.5% (95% confidence interval (CI): 25.5–31.6). The age- and sex-adjusted mortality rate in the HIV-infected population (40.7/1000 population) was four times higher than in the HIV-uninfected population (10.2/1000 population). Overall, the attributable fraction among the HIV-exposed was 0.71 (95% CI: 0.66–0.76) while the HIV population attributable fraction was 0.17 (95% CI: 0.14–0.20). In children the attributable fraction among the exposed and population attributable fraction were 0.92 (95% CI: 0.89–0.94) and 0.11 (95% CI: 0.08–0.15), respectively.

Conclusions

Over one quarter (28.5%) of decedents received by high-volume mortuaries in western Kenya were HIV-positive; overall, HIV was considered the cause of death in 17% of the population (19% of adults and 11% of children). Despite substantial scale-up of HIV services, HIV disease remains a leading cause of death in western Kenya. Despite progress, increased efforts remain necessary to prevent and treat HIV infection and disease.

Effect of the Test and Treat Strategy on Mortality Among HIV-Positive Adult Clients on Antiretroviral Treatment in Public Hospitals of Addis Ababa, Ethiopia

Background

The primary goal of antiretroviral therapy is to prevent human immune deficiency virus (HIV)-related morbidity and mortality. Deferring antiretroviral therapy (ART) until CD4 counts decline puts individuals with HIV at risk of HIV-related morbidity and mortality.

Objective

This study aims to assess the effect of the test and treat strategy on mortality among HIV-positive clients on ART in public hospitals in Addis Ababa.

Methods

A retrospective cohort study was conducted at five selected public hospitals in Addis Ababa. A cohort of 216 ART clients taken as an exposed group (test and treat" strategy) from 2017 to 2019 and 216 ART clients as an unexposed group taken from 2014 to 2017; totally, 432 clients were included in the study. Multivariate Cox regression was used to estimate the effect of the test and treat strategy on the survival of ART clients adjusting for other covariates.

Results

The 432 clients contributed to a total of 1025.17 person-years follow-up. Ninety-one (21.06%) of them died, 14.3% were unexposed and 6.7% were exposed (test and treat). The incidence of death was 92.4 and 81.8/1000 person-years in the unexposed group and exposed group, respectively, with an overall mortality rate of 88.8/1000 person-years. Besides, test and treat strategy (AHR: 0.31; 95% CI: 0.19, 0.52), baseline CD4 counts >350 cells/mm3 (AHR 0.40; 95%: CI: 0.20, 0.80), bedridden functional status (AHR 2.46; 95% CI: 1.41, 4.27), poor adherence (AHR 3.25; 95% CI: 1.410-7.51), moderate malnutrition on last visit (AHR 2.56; 95% CI: 1.30-5.04) and staying on original regimen (AHR 4.68; 95% CI 2.72, 8.07) were independent predictors of mortality.

Conclusion

Mortality among HIV patients on treatment decreased significantly since the start of the test and treat strategy. Therefore, test and treat strategy should be strengthened in all public and private facilities throughout the country.

Rate and Predictors of Mortality Among Adults on Antiretroviral Therapy at Debre Markos Referral Hospital, North West Ethiopia

Background

Human immunodeficiency virus/Acquired immunodeficiency syndrome is a chronic communicable disease with devastating global socio-economic, and political impacts commonly affecting the young and early adult populations. Ethiopia is doing well in controlling HIV/AIDS epidemic infection among African countries. This study set out to determine the mortality rate and its predictors among adults on antiretroviral therapy at Debre Markos Referral Hospital, northwest Ethiopia.

Methods

A hospital-based retrospective follow-up study was conducted from February to March 2018. A computer-generated simple random sample selected 480 cards of patients on antiretroviral therapy who were enrolled between February 2010 to January 2018. Epi-data Version 4.2 software was used for data entry and SPSS Version 25 for management and analysis. An adjusted hazard rate with a 95% confidence interval was used to identify significant predictors of mortality.

Results

The mortality rate was about 3.9 per 100 person-years. Cotrimoxazole prophylactic therapy (AHR: 2.99; 95% CI: 1.58, 5.70), being single (AHR: 2.37: 95% CI: 1.15, 4.87), non-disclosed status (AHR: 7.77; 95% CI: 3.76, 16.06), anemia (AHR: 2.16; 95% CI: 1.14, 4.09), bedridden (AHR: 6.11; 95% CI: 2.42, 15.41) or ambulatory (AHR: 2.16; 95%: 1.04, 4.51), presence of opportunistic infections (OIs) (AHR: 5.02; 95% CI: 1.70, 14.83) and tuberculosis (TB) co-infection (AHR: 5.57; 95% CI: 2.23, 13.88) were the significant predictors.

Conclusion and Recommendation

This study had a high mortality rate. Being single, bedridden, TB coinfection, anemia, and cotrimoxazole prophylaxis were the predictors of mortality. Therefore, psychological support and close follow-up for single, non-disclosed, non-adherent patients and early detection and treatment of anemia, tuberculosis, and OIs to reduce mortality is recommended.

Incidence of Mortality and Its Predictors Among HIV Positive Adults on Antiretroviral Therapy in University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia

Background

Despite the accessibility and higher coverage of antiretroviral therapy (ART), HIV/AIDS is a leading cause of morbidity and mortality in low- and middle-income countries. Ethiopia also shares the high burden of HIV/AIDS-related morbidity and mortality. Therefore, this study aimed to assess the incidence of mortality and its predictors among adult HIV patients on ART in the University of Gondar Comprehensive Specialized Hospital, northwest Ethiopia.

Patients and Methods

A retrospective follow-up study was conducted from January 2015 to January 2019 at the University of Gondar Comprehensive Specialized Hospital. A total of 475 patients who were on follow-up in this Hospital were included. The Cox proportional hazard model was fitted to assess the predictors of mortality. Both crude and adjusted hazard ratio (AHR) with their 95% confidence interval (CI) were calculated to show the strength of association. In multivariable analysis, variables with a P-value <0.05 were considered as statistically significant predictors of mortality.

Results

In this study, a total of 45 (9.5%) patients died with an incidence rate of 5.3 [95% CI: 3.4–7.1] per 100 person-years of observation. In the multivariable Cox regression analysis, the last known WHO stage III/IV [AHR= 15.02; 95% CI: 5.79–38.92], being anemic at baseline [AHR = 2.21; 95% CI: 1.02–4.78], and fair last known adherence level [AHR = 3.29; 95% CI: 1.39–7.78] were found to be significant predictors of mortality.

Conclusion

In this study, the incidence of mortality was relatively high. The rate of mortality may be minimized by paying particular attention to individuals with advanced WHO stage, anemia at the baseline, and those with adherence problems.

Survival and Predictors of Mortality Among Adult HIV/AIDS Patients Initiating Highly Active Antiretroviral Therapy in Debre-Berhan Referral Hospital, Amhara, Ethiopia: A Retrospective Study

Background

Acquired immune deficiency syndrome is one of the most destructive epidemics the world has ever witnessed. An estimated 36.9 million people were living with HIV in 2017. HIV/AIDS is the major contributing factor for morbidity and mortality in low- and middle-income countries. Although different studies on survival and predictors of mortality among HIV/AIDS patients after initiation of antiretroviral therapy were conducted, there are inconsistencies in the findings of those studies. Furthermore, to the authors’ knowledge, there was a dearth of studies conducted in this study area.

Purpose

The purpose of this study was to assess the survival and predictors of mortality among adult patients starting highly active antiretroviral therapy at Debre Berhan Referral Hospital, North Showa, Amhara, Ethiopia.

Patients and Methods

An institution-based retrospective study was conducted among the medical records of 447 study subjects’ selected using simple random sampling from January 1t, 2013 to December 30, 2018. The data was collected using a structured data abstraction checklist and analyzed using Kaplan–Meier statistics and Cox regression models.

Results

Among 447 adult patients, 54 patients (12.1%) had died, giving a crude death rate of 4.18 per 100 person years (95% CI=3.20–5.45). The overall estimated survival rate after initiation of antiretroviral therapy was 81.7% (95% CI=75.36–86.54%) at 72 months of follow-up. The independent predictors of mortality were clinical stage IV (HR=15.6, 95% CI=6.609–36.948), baseline opportunistic infections (HR=1.86, 95% CI=1.048–3.330), baseline Hgb<10 mg/dL (HR=4.655, 95% CI=2.253–9.619), baseline CD4<200 cells/µL (HR=4.71, 95% CI=2.275–9.751), the presence of comorbidity (HR=2.56 95% CI=1.391–4.740), being widowed (HR=3.475, 95% CI=1.412–8.550), and bedridden functional status (HR=3.069, 95% CI=1.111–8.480).

Conclusion

Patients with opportunistic infections, advanced clinical stage disease, bedridden functional status, baseline Hgb<10 mg/dL, baseline CD4<200 cells/µL, and comorbidity should be given special care.

Epidemiology of survival pattern and its predictors among HIV positive patients on highly active antiretroviral therapy in Southern Ethiopia public health facilities: a retrospective cohort study

BACKGROUND

In resource poor countries like Ethiopia, little is known about the survival of patients treated with antiretroviral therapy which depends on different factors. Evidence shows that mortality has been high particularly in the first 3 to 6 months of initiating antiretroviral therapy. Hence, the study aimed to assess the Epidemiology of survival pattern and its determinants among adult HIV positive patients on highly active antiretroviral therapy.

METHODS

Retrospective cohort study was employed among a total of 455 records of patients who were enrolled on antiretroviral therapy from September 2006 to August 2010. Socio-demographic, clinical, immunological, behavioral, and date of antiretroviral treatment initiation including date of follow up status were extracted. Significant predictor variables were identified by fitting Cox's proportional hazard model using a backward stepwise method and statistical significance variables were declared based on a p-value less than 0.05.

RESULTS

A total of 455 adult HIV/AIDS patients on ART contributed to 886.05-person-year of observation and 65.7% were alive and on treatment, 17.1% were lost to follow up and 7.5% died. The study showed that the estimated mortality was 4.4%, 5.3%, 6.1%, 7%, 7.5% and 7.5% at 6, 12, 24, 36, 48 and 60 months of follow up period, respectively. The overall incidence rate of mortality was 4.2 per 100 person-years of observation. In multivariate analysis age 45 and above (AHR: 3.72, 95% CI 1.21-11.4), bedridden functional status (AHR: 17.4, 95% CI 6.21-48.79), poor ART drug adherence (AHR: 4.52,95% CI 2.05-9.96), Tuberculosis co-infection (AHR: 4.1, 95% CI 1.84-9.13), non-disclosure (AHR: 4.9, 95% CI 1.82-12.89) and severe anemia (AHR: 5.1, 95% CI 1.81-14.21) were found predictors.

CONCLUSION

Patients with older age, tuberculosis infection, bedridden patients and severe anemia were predictors. Tracing poorly adhered patients and giving drug counseling as well as encouraging them for disclosure to their families is crucial to improve their survival.

Effect of tuberculosis infection on mortality of HIV-infected patients in Northern Tanzania

Background

TB and HIV are public health problems, which have a synergistic effect to each other. Despite the decreasing burden of these two diseases they still make a significant contribution to mortality. Tanzania is among the 30 high TB and HIV burden countries.

Methods

Routine data over 6 years from people living with HIV (PLHIV) attending health facilities in three regions of Northern Tanzania were analyzed, showing mortality trends from 2012 to 2017 for HIV and HIV/TB subpopulations. Poisson regression with frailty model adjusting for clustering at health facility level was used to analyze the data to determine mortality rate ratios (RR) and 95% confidence intervals (95%CI).

Results

Among all PLHIV the overall mortality rate was 28.4 (95% CI 27.6–29.2) deaths per 1000 person-years. For PLHIV with no evidence of TB the mortality rates was 26.2 (95% CI 25.4–27.0) per 1000 person-years, and for those with HIV/TB co-infection 57.8 (95% CI 55.6–62.3) per 1000 person-years. After adjusting for age, sex, residence, WHO stage, and bodyweight, PLHIV with TB co-infection had 40% higher mortality than those without TB (RR 1.4; 95% CI 1.24–1.67).

Conclusions

Over the 6-year period mortality rates for HIV/TB patients were consistently higher than for PLHIV who have no TB. More efforts should be directed into improving nutritional status among HIV patients, as it has destructive interaction with TB for mortality. This will improve patients’ body weight and CD4 counts which are protective against mortality. Among PLHIV attention should be given to those who are in WHO HIV stage 3 or 4 and having TB co-infection.

Adherence to antiretroviral therapy among HIV infected pregnant women in public health sectors: a pilot of Chilenje level one Hospital Lusaka, Zambia

Introduction

regular use of Antiretroviral Therapy (ART) in pregnancy and breastfeeding reduces the odds of Mother-to-Child HIV Transmission (MTCT). However, adherence to ART is critical for MTCT to be successful. The present study investigated factors that influence adherence to ART among HIV infected pregnant women in Zambia.

Methods

a cross-sectional study design was conducted involving 71 HIV infected pregnant women who were advised to join the Prevention of Mother-to-Child HIV Transmission (PMTCT) program during their routine Antenatal clinic (ANC) visit and were on ART for more than six months. We used the Medication Possession Ratio (MPR) to quantify adherence levels. We used logistic regression to establish factors that influence adherence to ART.

Results

a total of 71 HIV infected pregnant women with a median age of 27years (IQR, 25-30) were enrolled in the study. There was evidence of a difference in adherence levels between pregnant women above 30 years and ones between 15 years and 30 years (P<0.001). Median adherence levels in this group were found to be at 96%(IQR 89-97). The main predictor of adherence in this population was marital status (being on separation) and age. The women who were on separation were 0.14 times less likely to adhere to option B+ compared to married women.

Conclusion

adherence to option B+ among pregnant women is low. Adherence was significantly influenced by marital status (being on separation) and age. Efforts to improve adherence should be directed towards women on separation and young adults (< 30 years of age).

Effect of cardio-metabolic risk factors on all-cause mortality among HIV patients on antiretroviral therapy in Malawi: A prospective cohort study

Background

Cardiovascular disease (CVD) risk among people living with HIV is elevated due to persistent inflammation, hypertension and diabetes comorbidity, lifestyle factors and exposure to antiretroviral therapy (ART). Data from Africa on how CVD risk affects morbidity and mortality among ART patients are lacking. We explored the effect of CVD risk factors and the Framingham Risk Score (FRS) on medium-term ART outcomes.

Methods

A prospective cohort study of standardized ART outcomes (Dead, Alive on ART, stopped ART, Defaulted and Transferred out) was conducted from July 2014—December 2016 among patients on ART at a rural and an urban HIV clinic in Zomba district, Malawi. The primary outcome was Dead. Active defaulter tracing was not done and patients who transferred out and defaulted were excluded from the analysis. At enrolment, hypertension, diabetes and dyslipidemia were diagnosed, lifestyle data collected and the FRS was determined. Cox-regression analysis was used to determine independent risk factors for the outcome Dead.

Results

Of 933 patients enrolled, median age was 42 years (IQR: 35–50), 72% were female, 24% had hypertension, 4% had diabetes and 15.8% had elevated total cholesterol. The median follow up time was 2.4 years. Twenty (2.1%) patients died, 50 (5.4%) defaulted, 63 (6.8%) transferred out and 800 (85.7%) were alive on ART care (81.7% urban vs. 89.9% rural). In multivariable survival analysis, male gender (aHR = 3.28; 95%CI: 1.33–8.07, p = 0.01) and total/HDL cholesterol ratio (aHR = 5.77, 95%CI: 1.21–27.32; p = 0.03) were significantly associated with mortality. There was no significant association between mortality and hypertension, body mass index, central obesity, diabetes, FRS, physical inactivity, smoking at enrolment, ART regimen and WHO disease stage.

Conclusions

Medium-term all-cause mortality among ART patients was associated with male gender and elevated total/HDL cholesterol ratio.

Acute kidney injury and other factors associated with mortality in hiv-infected patients

OBJECTIVE

HIV-related mortality is still high, especially in developed countries. The aim of this study is to investigate factors associated to death in HIV-infected patients.

METHODS

This is a cross-sectional study with all HIV adult patients admitted to a tertiary infectious diseases hospital in Fortaleza, Northeast Brazil, from January 2013 to December 2014. Patients were divided into two groups: survivors and non-survivors. Demo-graphical, clinical and laboratory data were compared and a logistic regression was performed in order to investigate risk factors for death. P values ≤0.05 were considered statistically significant.

RESULTS

A total of 200 patients with mean age of 39 years were including in the study, 69.5% males. Fifteen patients (7.5%) died. Non-survivors presented a higher percentage of males (93.3 vs. 67.3%, p = 0.037). Non-survivors presented AKI (73.3 vs. 10.3%, p < 0.001), liver dysfunction (33.3 vs. 11.5, p = 0.031), dyspnea (73.3 vs. 33.0%, p = 0.002) and disorientation (33.3 vs. 12.4%, p = 0.025) more frequently. Non-survivors also had higher levels of urea (73.8 ± 52.7vs. 36.1 ± 29.1 mg/dL, p < 0.001), creatinine (1.98 ± 1.65 vs. 1.05 ± 1.07 mg/dL, p < 0.001), aspartate aminotransferase (130.8 vs. 84.8 U/L, p = 0.03), alanine aminotransferase (115.6 vs. 85.4 U/L, p = 0.045) and lactate dehydrogenase (LDH) (1208 vs. 608 U/L, p = 0.012), as well as lower levels of bicarbonate (18.0 ± 4.7 vs. 21.6 ± 4.6 mEq/L, p = 0.016) and PCO2 (27.8 ± 7.7 vs. 33.0 ± 9.3 mmHg, p = 0.05). In multivariate analysis, disorientation (p = 0.035, OR = 5.523, 95%CI = 1.130 - 26.998), dyspnoea (p = 0.046, OR = 4.064, 95%CI = 1.028 - 16.073), AKI (p < 0.001, OR = 18.045, 95%CI = 4.308 - 75.596) and disseminated histoplasmosis (p = 0.016, OR = 12.696, 95%CI = 1.618 - 99.646) and LDH > 1000 U/L (p = 0.038, OR = 4.854, 95%CI = 1.093 - 21.739) were risk factors for death.]CONCLUSION: AKI and disseminated histoplasmosis (DH) were the main risk factors for death in the studied population. Neurologic and respiratory impairment as well as higher levels of LDH also increased mortality in HIV-infected patients.
