Treatment for anemia in people with AIDS

Time to detection of anaemia and its predictors among women of reproductive-age living with HIV/AIDS initiating ART at public hospitals, Southwest Ethiopia: a multicentre retrospective follow-up study

OBJECTIVE

To assess the time to development of anaemia and its predictors among women of reproductive-age receiving antiretroviral therapy (ART) in public hospitals, Southwest Ethiopia.

DESIGN

Hospital-based retrospective follow-up study SETTING: Mizan-Tepi University Teaching Hospital, and Gebretsadik Shawo General Hospital Southwest Ethiopia.

PARTICIPANTS

A total of 389 records of women living with HIV/AIDS at public hospitals were reviewed using a systematic sampling method. The data were entered using Epi-Data Manager V.4.2 and exported to STATA V.14 for data analysis. A Cox-regression model was used and variables with a p-value of <0.05% and 95% confidence level in multivariable analysis were declared as statistically significant predictors for anaemia.

PRIMARY OUTCOME

Time to development of anaemia and its predictors among women of reproductive-age on ART in public hospitals.

RESULTS

Of 370 records of women of reproductive-age, 203 (54.86%, 95% CI (49.77% to 59.96%)) were anaemic with an incidence rate of 12.07 per 100 person months of observation, and the overall median survival time of 60 months. The total of 2.97%, and 80.26% of women were developed anaemia within the first 6 months and the last 6 months period of follow-up, respectively. Moreover, non-employed women, women with advanced WHO stage, women with baseline opportunistic infections and women who were on ART for long-duration were significantly associated with anaemia among women living with HIV/AIDS.

CONCLUSION

In this study, the incidence rate of anaemia was significantly high. The development of anaemia among women on ART was also increased with increased follow-up time. The risk of anaemia is increased in women living with HIV/AIDS due to advanced baseline WHO staging, presence of OIs at baseline, an increased duration on ART and low occupational status. Therefore, early identification and treatment of opportunistic infections and other coinfections are required to decrease the incidence of anaemia among women living with HIV/AIDS.

The impact of the 2014 Ebola epidemic on HIV disease burden and outcomes in Liberia West Africa

BACKGROUND

Detailed longitudinal studies of HIV-positive individuals in West Africa are lacking. Here the HIV prevalence, incidence, all-cause mortality, and the proportion of individuals receiving treatment with cART in two cohorts of participants in Ebola-related studies are described.

SETTING

Individuals of all ages were enrolled and followed at four sites in the area of Monrovia, Liberia.

METHODS

Two cohorts identified in response to the Ebola epidemic are described to provide insights into the current state of the HIV epidemic. HIV testing was performed at baseline for participants in both cohorts and during follow-up in one cohort.

RESULTS

Prevalence and incidence of HIV (prevalence of 3.1% for women and 1.4% for men and incidence of 3.3 per 1,000) were higher in these cohorts compared to 2018 national estimates (prevalence of 1.3% and incidence of 0.39 per 1,000). Most participants testing positive did not know their status prior to testing. Of those who knew they were HIV positive, 7.9% reported being on antiretroviral treatment. The death rate among those with HIV was 12.3% compared to 1.9% in HIV-negative individuals (adjusted odds ratio of 6.87). While higher levels of d-dimer were associated with increased mortality, this was not specific to those with HIV, however lower hemoglobin levels were associated with increased mortality among those with HIV.

CONCLUSION

These findings point to a need to perform further research studies aimed at fulfilling these knowledge gaps and address current shortcomings in the provision of care for those living with HIV in Liberia.

A possible role for hepcidin in the detection of iron deficiency in severely anaemic HIV-infected patients in Malawi

Introduction

Iron deficiency is a treatable cause of severe anaemia in low-and-middle-income-countries (LMIC). Diagnosing it remains challenging as peripheral blood markers poorly reflect bone-marrow iron deficiency (BM-ID), especially in the context of HIV-infection.

Methods

Severely anaemic (haemoglobin ≤70g/l) HIV-infected adults were recruited at Queen Elizabeth Central Hospital, Blantyre, Malawi. BM-ID was evaluated. Accuracy of blood markers (including hepcidin, mean corpuscular volume, mean cellular haemoglobin concentration, serum iron, serum ferritin, soluble transferrin receptor (sTfR), sTfR index, sTfR–ratio) to detect BM-ID was evaluated by ROC area under the curve (AUC^ROC).

Results

Seventy-three patients were enrolled and 35 (48.0%) had BM-ID. Although hepcidin and MCV performed best (AUC^ROC of 0.593 and 0.545 respectively) all markers performed poorly in identifying BM-ID (ROC<0.6). The AUC^ROC of hepcidin in males was 0.767 (sensitivity 80%, specificity 78%) and in women 0.490 (sensitivity 60%, specificity 61%).

Conclusion

BM-ID deficiency was common in severely anaemic HIV-infected patients. It is an important and potential treatable contributor to severe anaemia but lack of definitive biomarkers makes it difficult to accurately assess iron status in these patients. Further investigation of the potential of hepcidin is needed, including exploration of the differences in hepcidin results between males and females.

Severe anaemia complicating HIV in Malawi; Multiple co-existing aetiologies are associated with high mortality

BACKGROUND

Severe anaemia is a major cause of morbidity and mortality in HIV-infected adults living in resource-limited countries. Comprehensive data on the aetiology are lacking but are needed to improve outcomes.

METHODS

HIV-infected adults with severe (haemoglobin ≤70g/l) or very severe anaemia (haemoglobin ≤ 50 g/l) were recruited at Queen Elizabeth Central Hospital, Blantyre, Malawi. Fifteen potential causes and associations with anaemia severity and mortality were explored.

RESULTS

199 patients were enrolled: 42.2% had very severe anaemia and 45.7% were on ART. More than two potential causes for anaemia were present in 94% of the patients including iron deficiency (55.3%), underweight (BMI<20: 49.7%), TB infection (41.2%) and unsuppressed HIV infection (viral load >1000 copies/ml) (73.9%). EBV/CMV co-infection (16.5%) was associated with very severe anaemia (OR 2.8 95% CI 1.1-6.9). Overall mortality was high (53%; 100/199) with a median time to death of 17.5 days (IQR 6-55) days. Death was associated with folate deficiency (HR 2.2; 95% CI 1.2-3.8) and end stage renal disease (HR 3.2; 95% CI 1.6-6.2).

CONCLUSION

Mortality among severely anaemic HIV-infected adults is strikingly high. Clinicians should be aware of the urgent need for a multifactorial approach including starting or optimising HIV treatment, considering TB treatment, nutritional support and optimising renal management.
