Abstract
Medical professionals, particularly in regions with a high burden of human immunodeficiency virus (HIV), should be alert to the hematological complications of HIV, which may include cytopenias, malignancy, and coagulation disturbances. Patients may present with these conditions as the first manifestation of HIV infection. Hematological abnormalities are often multifactorial with opportunistic infections, drugs, malignancy, and HIV infection itself contributing to the clinical presentation, and the diagnosis should consider all these factors. Life-threatening hematological complications requiring urgent diagnosis and management include thrombotic thrombocytopenic purpura, superior mediastinal syndrome, spinal cord compression, and tumor lysis syndrome due to aggressive lymphoma. Antiretroviral therapy is the therapeutic backbone, including for patients with advanced HIV, in addition to specific therapy for the complication. This article reviews the impact of HIV on the hematological system and provides a clinical and diagnostic approach, including the role of a bone marrow biopsy, focusing on perspectives from sub-Saharan Africa.

Front Immunol 2023; 14:1296575. [PMID: 38193074 PMCID: PMC10773876 DOI: 10.3389/fimmu.2023.1296575] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Accepted: 12/04/2023] [Indexed: 01/10/2024] Open
Abstract
Hemophagocytic lymphohistiocytosis (HLH) is a rare but potentially life-threatening condition caused by excessive immune activation. Secondary HLH is usually triggered by infection, most often from viral infection or malignancy. Here, we present a case of secondary HLH, complicated by multiple organ dysfunction syndrome triggered by critical aseptic encephalitis. A 27-year-old man without any underlying disease presented to our hospital with fever, disturbance of consciousness, and generalized seizures. The patient was diagnosed with aseptic encephalitis with super-refractory status epilepticus. Although antiseizure medications and immunoglobulins were administered, the patient developed multiple organ dysfunction syndrome. HLH was later diagnosed based on hypertriglyceridemia, hyperferritinemia, splenomegaly, cytopenia, and phagocytosis of nucleated cells, as shown by a blood smear of bone marrow aspiration. Treatment with pulse steroid therapy and plasmapheresis was initiated rather than chemotherapy because of the patient's critical condition. However, the patient died of profound shock and multiple organ failure. Diagnosis of HLH is challenging in patients with severe infections because of similar clinical manifestations and laboratory findings. The early recognition of HLH provides patients with the opportunity to receive appropriate treatment, which can lead to increased survival and remission rates.

Prevalence, severity and associated risk factors of anemia among human immunodeficiency virus-infected adults in Sawla General Hospital, Southern Ethiopia: A facility-based cross-sectional study. PLoS One 2023; 18:e0284505. [PMID: 38085717 PMCID: PMC10715647 DOI: 10.1371/journal.pone.0284505] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Accepted: 11/06/2023] [Indexed: 12/18/2023] Open
Abstract
BACKGROUND Anemia is a significant public health problem in HIV/AIDS patients worldwide. This study is aimed to determine the prevalence of anemia and its risk factors among HIV-infected adults in Sawla General Hospital, southern Ethiopia. METHODS A facility-based cross-sectional study involving HIV-infected adults was conducted in ART clinic of Sawla General Hospital from April 01 to May 31, 2019. A systematic random sampling technique was employed to recruit the study participants. Socio-demographic and clinical data were collected using a structured questionnaire and checklist. Hemoglobin concentration from venous blood was determined by HemoCue® 301 analyzer. Descriptive and inferential statistics, by Statistical Package for Social Science version 26.0, were applied; p-values ≤ 0.05 in the multivariable logistic regression analysis were considered statistically significant. RESULTS A total of 220 HIV-infected adults participated in this study. The prevalence of anemia was 38.6%, from which 90.6, 7.1, and 2.3% are mild, moderate, and severe anemia, respectively. Anemia among HIV-infected adults was significantly associated with CD4 cell count below 200 cells/mm3 (AOR: 4.32; 95% CI: 2.10-8.86), clinical stage III or above (AOR: 4.20; 95% CI: 1.06-16.62), five or more years duration of HIV infection (AOR: 2.32; 95% CI: 1.08-4.94) and BMI below 18.5 kg/m2 (AOR: 3.82; 95% CI: 1.83-8.00). CONCLUSION Anemia is a moderate public health problem among the study population. Longer duration of HIV infection, advanced clinical stage, lower CD4 cell count, and BMI are risk factors for anemia. Therefore, early ART enrolment for HIV-infected adults with nutritional support and rigorous monitoring of CD4 cell count are essential to lower the prevalence.

Anemia in HIV Patients Attending Highly Active Antiretroviral Therapy Clinic at Hoima Regional Referral Hospital: Prevalence, Morphological Classification, and Associated Factors. HIV AIDS (Auckl) 2023; 15:621-632. [PMID: 37849793 PMCID: PMC10578157 DOI: 10.2147/hiv.s425807] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Accepted: 10/07/2023] [Indexed: 10/19/2023] Open
Abstract
Purpose To determine the prevalence of anemia, the morphological classification and to assess the factors associated with anemia among HIV patients attending Highly Active Antiretroviral Therapy (HAART) clinic at Hoima Regional Referral Hospital. Methods This was a cross-sectional study among 340 participants attending the HAART clinic at Hoima Regional Referral Hospital. Participants were recruited using a simple random sampling technique. A complete blood count (CBC) was performed using the Sysmex XN-550 hematology analyzer. Thick films were made and examined for malaria parasites, while thin films were examined for the morphological classification of anemia. Bivariate and multivariate logistic analyses were conducted using SPSS (version 23). Results Out of the 340 study participants, 255 (75%) were females, and the median age was 39 years (range: 6-76 years). The overall prevalence of anemia among the study participants was 16.8% (95% CI 13.1-21.1). Normocytic normochromic anemia was the most prevalent form of anemia (47.4%). The logistic regression at multivariate analysis showed that age groups (18-27 years, p = 0.017; 28-37 years, p = 0.005; and ≥38 years, p = 0.009), divorced marital status (p = 0.024), the presence of chronic disease (p = 0.010), a family history of anemia (p = 0.007), and the presence of malaria in the past one month (p = 0.001), presence of opportunistic infection (OR = 58, p = 0.000), use of antihelminthic drug in the past 3 months (OR = 0.10, p = 0.003) and unsuppressed viral load (OR = 10.74, p = 0.000) had a significant association with anemia. Conclusion Anemia is prevalent in HIV/AIDS patients who receive treatment at Hoima Regional Referral Hospital. Age, marital status, the presence of chronic illnesses, a family history of anemia, experiencing malaria in the past 3 months, the presence of opportunistic infections, the use of antihelminthic drugs in the past 3 months, and an unsuppressed viral load were significantly associated with anemia.

Abstract
Dysregulation of the bone marrow niche resulting from the direct and indirect effects of HIV infection contributes to haematological abnormalities observed in HIV patients. The bone marrow niche is a complex, multicellular environment which functions primarily in the maintenance of haematopoietic stem/progenitor cells (HSPCs). These adult stem cells are responsible for replacing blood and immune cells over the course of a lifetime. Cells of the bone marrow niche support HSPCs and help to orchestrate the quiescence, self-renewal and differentiation of HSPCs through chemical and molecular signals and cell-cell interactions. This narrative review discusses the HIV-associated dysregulation of the bone marrow niche, as well as the susceptibility of HSPCs to infection by HIV.

Abstract
Background Anemia has up to 87% prevalence in high tuberculosis (TB) and human immunodeficiency virus (HIV) burden settings of the sub-Saharan Africa (SSA) including Ethiopia. It increases lost to follow-up (LTFU) rate, reduces quality of life, and shortens the survival of TB/HIV coinfected patients. However, there is limited information on severity level and determinants of anemia in TB/HIV coinfected adults in the study setting in particular. Therefore, this study is aimed to assess severity level and determinants of TB/HIV-associated anemia. Methods A hospital based retrospective study was conducted among 305 TB/HIV coinfected adults who enrolled for antiretroviral therapy (ART) from January, 2009 to December, 2016 in two public hospital of Mekelle, Ethiopia, by reviewing ART register. A multiple logit model was fitted to identify the baseline determinants of anemia using 95% confidence level or 5% level of significance for adjusted odds ratio (AOR). Results In the current study, the cumulative baseline prevalence of anemia was 59.0% (95% CI: 53.3%-64.6%). Considering severity level, the prevalence was 6.2%, 28.2%, and 24.6% for severe, moderate, and mild anemia, respectively. Being female (AOR = 0.380; 95% CI: 0.226-0.640), body mass index (AOR = 0.913; 95% CI: 0.836-0.998) reduces the odds of developing anemia whereas baseline ambulatory functional status (AOR = 2.139; 95% CI: 1.189-3.846), bedridden functional status (AOR = 2.208; 95% CI: 1.002-4.863), HIV clinical stage III (AOR = 2.565; 95% CI: 1.030-6.384), and HIV clinical stage IV (AOR = 2.590; 95% CI: 1.006-6.669) increased the odds of developing anemia for TB/HIV coinfected adults. Conclusions In the current study, significant TB/HIV-associated severe anemia was assessed which accounted for nearly one-ninth of all anemia cases while nearly half were moderate anemia. Therefore, curious attention has to be given for the management of TB/HIV-associated severe anemia in particular and anemia in general to reducing anemia associated bad outcomes most importantly death.

Abstract
Thrombocytopenia is one of the complications in human immunodeficiency virus (HIV) patients. To improve the health outcomes of patients living with HIV, it is important to understand the prevalence and pattern of associated key clinical markers globally. This meta-analysis, therefore, aimed to estimate the pooled prevalence of and associated clinical marker of thrombocytopenia globally. Methodology: The meta-analysis was conducted as per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. All statistical analyses were conducted using Stata. Twelve full-text papers out of 454 were eligible for meta-analysis. Results: Among 6686 participants, overall pooled prevalence of thrombocytopenia was 10.90% (95% CI: 7.91, 13.88) I2 = 93.62%. In addition, thrombocytopenia was more prevalent by 25.11% (95% CI: 13.33, 36.88) in patients with CD + T < 200 cells/μL, and less prevalent in patients with CD + T < 200 cells/μL 10.10% (95% CI: 7.37, 12.83), respectively. Conclusions and recommendations: This meta-analysis established the prevalence of thrombocytopenia among patients living with HIV, and that it may be more prevalent in patients with CD + T < 200 cells/μL indicating the necessity of routine screening for various haematological markers and a careful treatment plan for HIV patients.

Abstract
Background Pancytopenia is a manifestation of numerous disease entities. The causes of pancytopenia differ with geographic region, socio-economic factors and HIV prevalence. Awareness of the common causes of pancytopenia may aid timely diagnosis. Objective This study aimed to determine the aetiology of pancytopenia in a South African population. Methods A retrospective observational study of adult patients presenting with pancytopenia at Tygerberg Academic Hospital, South Africa, from January 2016 to December 2017 was performed. Data on pancytopenia cases were obtained from the laboratory information system and utilised to determine the causes of pancytopenia. Results A total of 673 cases of pancytopenia were identified. The most common causes of pancytopenia were chemoradiation therapy (25%), sepsis (18%), haematological malignancy (9%), advanced HIV (7%), and megaloblastic anaemia (6%). The diagnostic yield of bone marrow examinations (BME) was 57% (n = 52/91). The aetiology of pancytopenia differed according to age, with malignancy being a more common cause of pancytopenia among the elderly. Conclusion Several easily recognisable and treatable conditions can manifest as pancytopenia. Prompt management of such conditions, notably sepsis and megaloblastic anaemia, can result in the resolution of the cytopenias and negate the need for a BME. However, haematological malignancy and unexplained pancytopenia strongly rely on a BME to establish a diagnosis. Pancytopenia investigations, when guided by appropriate clinic-laboratory findings, can promptly identify the underlying aetiology, while also identifying cases where an expedited BME is required. This is valuable in resource-conscious medicine.

Abstract
Background Hematologic abnormalities are common complications of patients infected with HIV associated with accelerated deterioration in CD4+ cell counts, disease progression, poor quality of life and death. Few studies have evaluated the magnitude of cytopenias at the initiation of antiretroviral therapy (ART) in sub-Saharan Africa. The aim of this study was to determine the prevalence and predictors of cytopenias among HIV-infected adults at initiation of ART in a resource-limited setting in Ethiopia. Methods A cross-sectional study was conducted among HIV-infected adults initiating ART at the HIV care and treatment clinic of Mehal Meda Hospital between September 2008 and June 2019. Demographic, clinical and laboratory data of patients were collected from medical records. Anemia was defined according to WHO guidelines as hemoglobin concentration <12 g/dl for non-pregnant females and <13 g/dl for males. Leucopenia was defined as total white blood cell count <4.0 × 103 cells/μL and thrombocytopenia as platelet count <150 × 103 cells/μL. Logistic regression analysis was used to determine factors associated with the presence of cytopenias. Results Out of the total 566 patients included, 36.6% (95% CI 32.7–40.6%) had anemia, 17.1% (95% CI 14.2–20.4%) had leucopenia and 14.5% (95% CI 11.8–17.6%) had thrombocytopenia. A total of 53.2% (95% CI 49.1–57.3%) of patients had at least one form of cytopenia, 14.1% (95% CI 11.4–17.2%) had bicytopenia, and only 0.5% had pancytopenia. Factors associated with the presence of any cytopenia in multivariable analysis were male sex, advanced clinical disease stage, low CD4+ cell count, low BMI, and decreased renal function. Conclusion A substantial burden of cytopenias was detected among HIV-infected adults enrolled for care and treatment services in our setting. Patients with HIV infection should be screened for hematological abnormalities at initiation of ART because of its potential for morbidity and mortality during ART.

Abstract
Background Although antiretroviral therapy has significantly altered the natural history of human immunodeficiency virus infection and improved the quality of life of patients, there are conflicting reports regarding its impact on hematological outcomes. Thus, this study aimed at investigating the prevalence and predictors of anemia among adults on antiretroviral therapy in Northeast Ethiopia. Materials and methods A retrospective cohort study was carried out among adults who began antiretroviral treatment between September 2005 and January 2019 at two governmental hospitals in Dessie town. Data were collected from patients’ medical records using a pretested data extraction instrument. Anemia was the primary outcome variable of the study. It was defined based on WHO criteria after adjustment for altitude and smoking status of measured values. Data were entered and validated using EpiData Version 3.1 and then exported to SPSS Version 20.0 for analysis. Descriptive analysis was done for prevalence and binary logistic regression was carried out to assess whether covariates were associated with experiencing anemia. Statistical significance has been considered at p-value <0.05. Results Medical records of 392 patients (mean age: 35.58 ± 9.46 years) were reviewed. Of the total 392 patients, 218 (55.6%) were females, 261 (66.6%) were categorized under WHO clinical stage III/IV and 134 (34.2%) had a baseline CD4 cell count of <100 cells/mm3. The mean baseline CD4 cell count was 179 cells/mm3 (range: 2 to 853 cells) and 230 (58.7%) of the participants were on zidovudine-based regimen. Anemia was diagnosed among 162 (41.3%) patients. After adjustment for other confounding factors, risk of anemia was significantly associated with low baseline CD4 cell count (AOR 1.80, 95% CI 1.05–3.06) and tenofovir based regimen (AOR 2.05, 95% CI 1.31–3.21). On the other hand, being educated was found to be protective (AOR 0.40, 95% CI 0.21–0.78). Conclusion In this research, the prevalence of anemia was relatively high. Low baseline CD4 cell count and tenofovir based regimen were independent predictors of anemia; while being educated was protective. Treatment programs should focus on early diagnosis and treatment of HIV as well as routine screening and proper treatment of anemia.

Abstract
Background Patients with HIV have a higher prevalence of thrombocytopenia than those without HIV infection, increasing their risk of substantial perioperative blood loss (PBL) during total hip arthroplasty (THA). This study aimed to evaluate PBL risk factors in HIV-infected patients undergoing THA. Methods Eighteen HIV+ patients (21 hip joints) and 33 HIV− patients (36 joints) undergoing THA were enrolled in this study. PBL was calculated using the Gross equation, which comprises total blood loss (TBL), dominant blood loss (DBL), and hidden blood loss (HBL). Risk factors for post-THA PBL in both patient populations was evaluated using multivariable linear regression. Results At baseline, the HIV+ patients were younger, more likely to be male and to have elevated hemoglobin and albumin levels, and lower erythrocyte sedimentation rates than HIV− patients. There were no differences in the T-lymphocyte subsets or coagulation function between the two groups. Age and albumin level were identified as potential HBL risk factors after THA, and albumin level was associated with higher TBL. The unadjusted linear regression analysis showed that the HBL and TBL were significantly higher in HIV+ patients than in HIV− patients. However, after adjusting for other factors, no differences in DBL, HBL, or TBL were observed between HIV− and HIV+ patients. Conclusion PBL was similar in both groups undergoing THA, regardless of their HIV-infection status. THA surgery is a safe and effective procedure in HIV+ patients.

Abstract
BACKGROUND Anemia is the most frequent hematologic abnormality among people living with human immunodeficiency virus (HIV) (PLWHIV) and is associated with HIV disease progression and higher risk of mortality of the patients. However, there is a wide variation of the prevalence of anemia among PLWHIV in different clinical settings. We aimed to obtain more precise estimates of prevalence of anemia and severity of anemia among PLWHIV, which may be important for patients, caregivers, researchers and health policy-makers. METHODS We systematically searched PubMed, EMBASE, Web of Science, and Cochrane Library for original articles reporting the prevalence of anemia defined using age and sex-specific hemoglobin levels according to World Health Organization criteria among PLWHIV from inception to August 31, 2021. We used DerSimonian-Laird random-effects meta-analyses to obtain pooled prevalence and 95% confidence intervals (CIs) of anemia and severity of anemia among PLWHIV. A univariable meta-regression has been conducted to assess the association between anemia prevalence and study characteristics, including study design, median year of sampling, geographical region, World Bank Income level, and proportion of antiretroviral therapy (ART). FINDINGS We included 63 observational studies covering 110,113 PLWHIV. The pooled prevalence of anemia was 39.7% (95% CI: 31.4%-48.0%) for children living with HIV aged <15 years, 46.6% (95% CI: 41.9%-51.4%) for adults (men and non-pregnant women) living with HIV aged ≥15 years, and 48.6% (95% CI: 41.6%-55.6%) for pregnant women living with HIV. Among adults living with HIV, the pooled prevalence of severity of anemia was 21.6% (95% CI: 19.9%-23.3%), 22.6% (95% CI: 14.8%-30.4%), and 6.2% (95% CI: 4.4%-8.1%) for mild, moderate and severe anemia, respectively. Compared with East Africa, anemia prevalence among adults living with HIV was higher in Southern Africa (p = 0.033). INTERPRETATION Anemia is prevalent among PLWHIV. Thus, policies, strategies, and programs should be considered to identify the predictors of anemia among PLWHIV to reduce the burden of anemia among patients in the ART era.

Abstract
Background At present, the thrombocyte abnormality is not well described before and after the initiation of antiretroviral therapy (ART). The purpose of this research is to investigate the dynamic changes and related risk factors of thrombocytopenia and thrombocytosis in HIV-infected individuals. Methods We performed a real-world observational study among 6637 HIV patients who started ART from January, 2013 to August, 2020 at the Beijing Ditan Hospital. Hazard indicators linked with thrombocytopenia and thrombocytosis were analyzed by logistic/Cox regression. Results The prevalence of thrombocytopenia and thrombocytosis was 2.65% and 5.85% among ART-naïve patients, respectively. Correlated risk factors: (thrombocytopenia) older age, coinfection with HBV, leucopenia, anemia, and CD4 count <350 cells/uL; (thrombocytosis) WBC level ≥4.0 x 109/L, anemia, NLR ≥2.0, and CD4 count ≥350 cells/uL. As for the recovery rate, it was 86.6/54.2, 83.4/46.3, 66.0/35.1, and 65.3/ 33.9 per 100 PYFU in thrombocytopenia/thrombocytosis at different treatment period (12m, 24m, 36m, and 48m). While the new-onset incidence of thrombocytopenia/thrombocytosis at different ART period (12m, 24m, 36m, 48m, 60m, 72m, and 84m) was 0.25/7.2, 0.19/6.31, 0.16/4.74, 0.16/4.55, 0.16/4.48, 0.15/4.41, and 0.15/4.39. And the driving forces of thrombocytosis were antiretroviral treatment, female, overweight, and WBC level ≥ 4.0 x 109/L. Conclusion In the medical practice, while paying attention to thrombocytopenia, clinicians should be highly vigilant about the thrombocytosis of HIV/AIDS patients, and related treatment strategies need to be further studied.

Abstract
BACKGROUND HIV can interrupt the normal development of bone marrow cell lines. Bone marrow aspiration/biopsy (BMA/B) has been described as a diagnostic tool in AIDS patients with fever of unknown origin (FUO). In this review, we aimed to study patients with AIDS who had undergone a BMA/B to investigate FUO and describe the pathologies diagnosed in the biopsy. METHODS Thirty-four BMA/B samples were collected from AIDS patients admitted for work-up of FUO to the infectious disease ward of a tertiary referral HIV center in Tehran, Iran, between September 2014 and September 2015. Data including age, sex, duration of disease, CD4 cell counts, hepatitis B (HBV) and C (HCV) coinfection, the primary presentation of AIDS, and the treatment history were retrieved and analyzed. Patients underwent BMA/B. An expert pathologist reviewed the BMA/B specimens. RESULTS The mean age of the patients was 37.5 years (range, 26-56), and 27 (79%) were men. Twenty-seven (79%) patients contracted HIV from injection drug use, and 7 (21%) via sexual transmission. Only 3 (9%) of the BMA/B examinations were normal. Hypocellular bone marrow was diagnosed in 22 (65%) patients. Other pathologies included granulomas in 6 (18%), hematologic malignancies in 2 (6%), and leishmaniasis Aspergillosis, each in 1 (3%) patient. Six (17%) of the specimens were found to have tuberculosis infections. CONCLUSION Hypocellular bone marrow was the most common pathology on BMA/B examinations, followed by the presence of granulomas. Tuberculosis, Aspergillosis, and Leishmaniasis the opportunistic infections diagnosed on BMA/B specimens. Our results support BMA/B as an appropriate diagnostic tool for early diagnosis of opportunistic infections and malignancies in AIDS. BMA/B is indispensable in the armament of diagnostic tools of the physicians managing AIDS patients.

Abstract
Hematologic changes are frequent complications in people living with HIV/AIDS (PLWHA). Anemia and thrombocytopenia are the most frequent multifactorial hematologic abnormalities and are associated with a low quality of life and high death rates. This study aims to describe the prevalence of anemia and thrombocytopenia in PLWHA and to identify the main clinical characteristics that aggravate these conditions in studies published in the last 10 y. A comprehensive search was performed on the PUBMED database, using the terms ‘HIV infection and anemia’ and ‘HIV infection and thrombocytopenia’. Additional searches were made in the reference lists of articles covering the theme. The selected studies reported an overall prevalence of anemia from 7.2% to 84% and of thrombocytopenia from 4.5% to 26.2%. The prevalence of thrombocytopenia and anemia were aggravated by a CD4+ T lymphocyte count of <200 cells/μL, increased viral load and coinfections or opportunistic infections. Antiviral therapy (ART) shows a beneficial effect, reducing the frequencies of thrombocytopenia and anemia, except in a zidovudine-based ART regimen, which worsens the anemic condition. Because anemia and thrombocytopenia are treatable comorbidities associated with increased mortality among PLWHA, physicians should monitor these risk factors in order to establish better interventions and reduce morbidity and mortality in PLWHA.

Abstract
Objectives Hematological abnormalities of the major blood cell lines are frequently reported in patients with HIV-1 infection, in patients without antiretroviral therapy, and during the advanced stages of the disease. Chronic immune activation and inflammation results in the progressive depletion of CD4+ T-cells play a significant role in the clinical progression and pathogenesis of this infection. This study was aimed at assessing the prevalence of hematological abnormalities and their associated factors before and after the initiation of antiretroviral therapy in adults with HIV-1 infection in a referral hospital. Methods The study was conducted from 1 April to 30 June 2018, at Goba Referral Hospital. A total of 308 HIV-positive adults on treatment were enrolled during the study period. Socio-demographic and clinical data were collected using a structured questionnaire, with pre-highly active antiretroviral therapy data were extracted from medical records while post-treatment immuno-hematological measurements were done on blood samples collected at the time of enrollment. Results The prevalence of anemia, leukopenia, and thrombocytopenia before initiation of antiretroviral treatment was higher, although anemia and thrombocytopenia decreased correspondingly after initiation of treatment leukopenia increased by 4%. Mean values of immuno-hematological parameters before and after treatment initiation were significant (p < 0.05). CD4+ T-cell count <200 cells/µL was the only independent risk factor for anemia and leukopenia before highly active antiretroviral therapy, while stage IV disease, female sex, zidovudine, lamivudine, and nevirapine treatment, and intestinal parasite infection were predictors of anemia after treatment initiation. Conclusion The study revealed that hematological abnormalities are common in HIV infection, while the occurrence of abnormalities after highly active antiretroviral therapy initiation. Different risk factors are associated with hematological abnormalities at pre- and post-highly active antiretroviral therapy with regular monitoring of risk factors, adherence to the early initiation of highly active antiretroviral therapy, and conduct of further longitudinal studies are recommended.

Abstract
Introduction Hematologic abnormalities are frequent among persons living with HIV (PLWH). The bone marrow aspirate (BMA) and biopsy (BMB) are commonly performed in the diagnostic approach of patients with unexplained cytopenias. Changes in antiretrovirals, supportive therapy and increased life expectancy have modified the distribution and etiology of cytopenias, questioning their use. Our aim was to analyze the diagnostic yield of BMA, BMB and marrow cultures for the evaluation of cytopenias in PLWH. Methods This was a retrospective cohort of ≥ 18-year-old PLWH undergoing bone marrow assessment (MA) for the evaluation of cytopenias between January 2002 and December 2015. Results A total of 236 cytopenic events were analyzed, 47.9% being PLWH who had a longstanding diagnosis (≥ 1 year). Adherence to antiretrovirals was 63.5%. Anemia was seen in 91.9% and pancytopenia in 39%. Common presentations included fever (52.1%), weight loss (42.8%) and adenopathies (28.8%). Median days from detection to MA was 5 (0 – 63 days). Most common etiologies were non-HIV infectious diseases (31.4%) and benign/malignant hematologic diseases (26.3%). The diagnostic yield was 16.1% for BMA, 20.3% for BMB, 30.5% for both and 35.6% when cultures were added. Patients most likely to have conclusive MA were those with moderate/severe thrombocytopenia (p = 0.007). Fever, splenomegaly, and low CD4+ counts were associated with infectious etiologies, while hematologic diagnoses were related to the presence of adenopathies. Conclusion As a minimally invasive intervention, the MA has a high yield for identifying the etiology of cytopenic events in PLWH, being conclusive in one in three patients. Early performance could lead to prompt diagnosis and timely therapy initiation.

Abstract
This paper has proposed an effective intelligent prediction model that can well discriminate and specify the severity of Coronavirus Disease 2019 (COVID-19) infection in clinical diagnosis and provide a criterion for clinicians to weigh scientific and rational medical decision-making. With indicators as the age and gender of the patients and 26 blood routine indexes, a severity prediction framework for COVID-19 is proposed based on machine learning techniques. The framework consists mainly of a random forest and a support vector machine (SVM) model optimized by a slime mould algorithm (SMA). When the random forest was used to identify the key factors, SMA was employed to train an optimal SVM model. Based on the COVID-19 data, comparative experiments were conducted between RF-SMA-SVM and several well-known machine learning algorithms performed. The results indicate that the proposed RF-SMA-SVM not only achieves better classification performance and higher stability on four metrics, but also screens out the main factors that distinguish severe COVID-19 patients from non-severe ones. Therefore, there is a conclusion that the RF-SMA-SVM model can provide an effective auxiliary diagnosis scheme for the clinical diagnosis of COVID-19 infection.

Effects of undernutrition on mortality and morbidity among adults living with HIV in sub-Saharan Africa: a systematic review and meta-analysis. BMC Infect Dis 2021; 21:1. [PMID: 33390160 PMCID: PMC7780691 DOI: 10.1186/s12879-020-05706-z] [Citation(s) in RCA: 195] [Impact Index Per Article: 65.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2020] [Accepted: 12/11/2020] [Indexed: 01/04/2023] Open
Abstract
Background Undernutrition is one of the most common problems among people living with HIV, contributing to premature death and the development of comorbidities within this population. In Sub-Saharan Africa (SSA), the impacts of these often inter-related conditions appear in a series of fragmented and inconclusive studies. Thus, this review examines the pooled effects of undernutrition on mortality and morbidities among adults living with HIV in SSA. Methods A systematic literature search was conducted from PubMed, EMBASE, CINAHL, and Scopus databases. All observational studies reporting the effects of undernutrition on mortality and morbidity among adults living with HIV in SSA were included. Heterogeneity between the included studies was assessed using the Cochrane Q-test and I2 statistics. Publication bias was assessed using Egger’s and Begg’s tests at a 5% significance level. Finally, a random-effects meta-analysis model was employed to estimate the overall adjusted hazard ratio. Results Of 4309 identified studies, 53 articles met the inclusion criteria and were included in this review. Of these, 40 studies were available for the meta-analysis. A meta-analysis of 23 cohort studies indicated that undernutrition significantly (AHR: 2.1, 95% CI: 1.8, 2.4) increased the risk of mortality among adults living with HIV, while severely undernourished adults living with HIV were at higher risk of death (AHR: 2.3, 95% CI: 1.9, 2.8) as compared to mildly undernourished adults living with HIV. Furthermore, the pooled estimates of ten cohort studies revealed that undernutrition significantly increased the risk of developing tuberculosis (AHR: 2.1, 95% CI: 1.6, 2.7) among adults living with HIV. Conclusion This review found that undernutrition has significant effects on mortality and morbidity among adults living with HIV. As the degree of undernutrition became more severe, mortality rate also increased. Therefore, findings from this review may be used to update the nutritional guidelines used for the management of PLHIV by different stakeholders, especially in limited-resource settings.

Abstract
Introduction Hematologic abnormalities are common in HIV and involve all blood cell lineages. A study on cytopenias, as correlated with disease progression, can be valuable in resource-limited settings. This study aimed to determine the hematologic profile of HIV patients and its association with CD4 count and antiretroviral (ARV) treatment. Methods This is a retrospective cohort study involving adult Filipino HIV patients with complete blood count (CBC) and CD4 count determinations prior to the initiation of ARV treatment and after ≥6 months of ARV treatment. Logistic regression was performed to determine the association between cytopenias and a CD4 count <200 cells/µL. Results The study included 302 patients. Anemia was the most common cytopenia. Anemia and leukopenia were associated with an increased likelihood of having a CD4 count <200 cells/µL in ARV-naïve patients. In ARV-treated patients, leukopenia was associated with an increased probability of having a CD4 count <200 cells/µL. An increase in hemoglobin, white blood cell (WBC) and platelet counts was observed after ≥6 months of ARV treatment. Conclusion Anemia and leukopenia can be used as markers of immune status in HIV-infected individuals and improvement in the CBC parameters can be used to assess response to ARV treatment. Routine monitoring of hematologic parameters is recommended.

Prevalence of cytopenia and its associated factors among HIV infected adults on highly active antiretroviral therapy at Mehal Meda Hospital, North Shewa Zone, Ethiopia. PLoS One 2020; 15:e0239215. [PMID: 32931523 PMCID: PMC7491728 DOI: 10.1371/journal.pone.0239215] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2020] [Accepted: 09/01/2020] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Cytopenias affect the outcomes of highly active anti-retroviral therapy that results in higher morbidity, mortality, and impaired quality of life. The purpose of this study was to assess the prevalence of cytopenia and its associated factors among HIV infected adults on highly active antiretroviral therapy at Mehal Meda Hospital, North Shewa Zone, Ethiopia. METHOD A cross-sectional health facility based study was conducted among 499 consecutively selected adult HIV infected patients taking HAART for at least six months from January to April 2018. The study participant's socio-demographic and clinical information was collected using a pre-tested questionnaire and reviewing of medical records by trained clinical nurses. Complete blood count and CD4 T cell count were determined by Sysmex KX-21 N and BD FACS count respectively. Bivariate and multivariate analysis was performed to identify the independently associated factors of cytopenia and prevalence ratios and their 95% confidence intervals were estimated using Poisson regression model with robust error variance to quantify the strength of statistical association. In all cases, a P value less than 0.05 was considered statistically significant. RESULT Out of the total study participants, 39.9% had at least one form of cytopenia, 23.2% had anemia, 13.8% had leukopenia, 12.4% had thrombocytopenia, 11.62% had bi-cytopenias, and only 1% had pancytopenia. In multivariate analysis, cytopenia was independently associated with older age groups, male gender, ZDV based regimen, and CD4 count less than 200 cells/mm3. CONCLUSIONS In this study, the magnitude of any cytopenia was 40% among adult HIV infected patients taking highly active antiretroviral therapy and the prevalence increased as the CD4 count decreases. Therefore, these warrant the need for monitoring hematological parameters of HIV infected patients on HAART to reduce morbidity and mortality.

Abstract
The association between opportunistic infection (OI) and anaemia among HIV-infected patients remains to be studied. We investigated the prevalence and risk factors of anaemia in hospitalised HIV-infected patients to reveal the association between OI and anaemia. We conducted a retrospective study of HIV-positive hospitalised patients from June 2016 to December 2017 in Mengchao Hepatobiliary Hospital of Fujian Medical University. Patients’ information on socio-demographic and clinical characteristics were carefully collected. The comparison of anaemia prevalence between groups was conducted with χ2 test. A logistic regression model was carried out to analyse the predictors of anaemia. The total prevalence of anaemia in hospitalised HIV-infected patients was 55.15%. The prevalence of mild, moderate and severe anaemia was 41.42%, 11.08% and 2.64%, respectively. Predictors independently associated with anaemia were: CD4 counts <50 cells/μl (odds ratio (OR): 6.376, 95% confidence interval (CI) = 1.916–21.215, P = 0.003), CD4 counts 50–199 cells/μl (OR: 6.303, 95% CI = 1.874–21.203, P = 0.003), co-infection with tuberculosis (TB) (OR: 2.703, 95% CI = 1.349–5.414, P = 0.005) or Penicillium marneffei (PM) (OR: 7.162, 95% CI = 3.147–15.299, P < 0.001). In Fujian, China, more than half inpatients with HIV were anaemic, but severe anaemia is infrequent. Lower CD4 counts, co-infection with TB or PM were independent risk factors for anaemia. Chinese HIV patients especially with TB, PM infection and low CD4 level should be routinely detected for anaemia to improve therapy.

Abstract
Background Bone marrow aspiration and trephine biopsy (BMAT) are widely performed in adults to evaluate haematological and malignant conditions. However, the diagnostic yield from the procedure in unselected patients in the South African public sector has not previously been described. Objectives We identified the main indications and most common diagnoses encountered for BMAT and described the demographic and blood profiles of patients, including HIV-positive patients, who had undergone the procedure at a tertiary hospital in KwaZulu-Natal. Methods We retrospectively reviewed laboratory data from January 2016 to December 2016 for all patients aged ≥ 13 years who underwent the procedure and stratified findings by demographic data. Results Among 120 BMAT biopsies studied, 80 (67%) cases were performed to evaluate suspected malignancy and a further 40 (33%) cases for non-malignant indications. The main indications for bone marrow examination were: cytopenias 38 (32%), lymphoma 35 (29%), leukaemia 21 (18%), and multiple myeloma 17 (14%). BMAT results revealed that 60 cases (50%) were malignant in origin, 30 cases (25%) were non-malignant and 30 cases (25%) were classified as normal. The common diagnoses were: leukaemia, 24 (20%); multiple myeloma, 16 (13%) and lymphoma, 13 (11%). Cases aged ≥ 50 years were more likely to have a malignant diagnosis (odds ratio: 5.8 (95% confidence interval: 2.2–17.1) p-value < 0.001). Conclusion The diagnostic yield of BMAT was high, with significant abnormalities detected in three quarters of cases. Haematological malignancy was the more common diagnosis. Increasing age was associated with an increase in reporting of haematology malignancy.

Abstract
Background Cytopenia is a frequent hematological disorder in patients with human immunodeficiency virus (HIV) infection. However, the distribution and risk factors of cytopenia in patients starting highly active anti-retrovirus treatment (HAART) and the effect of HAART on cytopenia were not fully investigated. Methods From November 2004 to August 2016, a retrospective study was conducted to evaluate the prevalence of cytopenia in 4325 HAART-naïve patients. Risk factors of cytopenia at baseline and on recovery from cytopenia were analyzed using logistic regression analysis after 24 months of HAART in Beijing Ditan Hospital. Results The prevalence of cytopenia was 19.1% in HIV-naïve patients. Risk factors for cytopenia in HAART-naïve patients were a CD4 cell count<200 cells/μL, femaleness, WHO stage IV, coinfection with hepatitis B virus (HBV), BMI <18.5 kg/m2, a viral load ≥100,000 copies/ml, and age ≥40 years. In total, 70.2% and 76.4% of patients with cytopenia recovered after 6 and 24 months of HAART, respectively. The predictors of patients without normal blood cells after 24 months HAART were a CD4 cell count of <200 cells/μL, femaleness, WHO stage IV, coinfection with hepatitis B virus (HBV), BMI <18.5 kg/m2, a viral load ≥100,000 copies/ml, and age ≥40 years. In total, 70.2% and 76.4% of patients with cytopenia recovered after 6 and 24 months of HAART, respectively. The predictors of patients without normal blood cells after 24 months HAART were a CD4 cell count of <200 cells/ Conclusion Early detection could decrease the prevalence of HIV-related cytopenia, while starting HAART as early as possible seems to be effective for normalization of the blood cells in HIV-infected patients.

Evolution of Anemia Types During Antiretroviral Therapy-Implications for Treatment Outcomes and Quality of Life Among HIV-Infected Adults. Nutrients 2019; 11:nu11040755. [PMID: 30935133 PMCID: PMC6521252 DOI: 10.3390/nu11040755] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2019] [Revised: 03/24/2019] [Accepted: 03/27/2019] [Indexed: 12/13/2022] Open
Abstract
This study examined whether the type of anemia in persons living with HIV/AIDS (PLWHA) changed from the beginning of highly antiretroviral therapy (HAART) and had implications for treatment outcomes and quality of life (QOL). If present, the anemia-type was defined as microcytic, macrocytic or anemia of chronic disease (ACD) at study months 0, 6, 12, and 18. Multinomial logistic regression quantified sociodemographic and HIV-treatment factors associated with incident microcytic anemia or ACD over 18 months. Repeated measures linear regression models estimated the anemia-type associated change in the CD4 cell-count, QOL, body mass index (BMI) and frailty over 18 months. Cox proportional hazard models estimated associations between anemia-type and time to (a) gain at least 100 CD4 cells/L and (b) hospitalization/death. Analyses were implemented in Statistical Analysis Software (v.9.4) from which odds ratios (ORs) mean differences (β) and corresponding 95% confidence intervals (CI) were estimated. At enrollment, ACD, macrocytic and microcytic anemia was present in 36.8% (n = 147), 11.3% (n = 45) and 9.5% (n = 38), respectively with 42% (n = 170) anemia-free. By the study end, only 23% (n = 115) were without anemia. Among the 251 with anemia at the study end, 53.3% (n = 195) had macrocytic anemia, 12.8% (n = 47) had ACD and 2.5% (n = 9) had microcytic anemia. Incident macrocytic anemia was positively associated with baseline hyperferritinemia (OR = 1.85, 95%CI: 1.03⁻3.32), inversely associated with wealth (OR = 0.87, 95%CI: 0.67⁻1.03) and inversely associated with efavirenz-containing HAART (OR = 0.42, 95%CI: 0.21⁻0.85). ACD incidence decreased by 53% (95%CI: 0.27⁻0.79) per 100 cells/L increase in baseline CD4-cell count and decreased by 90% (95%CI: 0.01,0.87) among adults treated with nevirapine-containing HAART. ACD was associated with a lower BMI at months 6 (β = -0.33, 95% CI: -0.64, -0.01) and 12 (β = -0.41, 95%CI: -0.73, -0.09), with lower QOL (β = -3.2, 95%CI: -5.94, -0.53) at month 12 and with elevated frailty (β = 1.2; 95%CI: 0.46, 1.86) at month 12. Macrocytic anemia did not predict a post-enrollment change in CD4, BMI or QOL during follow-up. However, the time to gain 100 CD4 cells/L was 43% slower (p < 0.05) and the frailty was higher at month 12 for PLWHA with the baseline or sustained macrocytic vs. no anemia. A substantial decline in ACD and microcytic anemia occurred in tandem with large increase in the macrocytic anemia over 18 months on HAART. Interventions to mitigate all anemia-particularly ACD, is expected to improve the immune recovery rate, lower frailty, and enhanced QOL.

Abstract
Background Hematologic abnormalities involving peripheral blood cell cytopenias are strong predictors of morbidity, mortality and poor antiretroviral therapy (ART) outcomes of HIV infected individuals. However, limited studies are conducted in resource-limited settings of sub-Saharan Africa that have addressed the magnitude and associated factors of cytopenias. This study aimed to investigate the magnitude and associated factors of cytopenias among ART naïve HIV infected adult Ethiopians. Materials and methods A cross-sectional study was conducted among ART naïve HIV infected individuals attending at ART unit of Dessie Referral Hospital between November 01, 2015 and April 30, 2016. A total of 402 adults were included using consecutive sampling. Socio-demographic, clinical and laboratory data of patients were collected. The data were entered to Epi Info version 3.4.3 and analyzed using SPSS version 20 software (SPSS INC, Chicago, IL, USA). Factors associated with cytopenias were analyzed first using bivariate and then multivariate logistic regression models. An odds ratio with 95% confidence interval was used to measure the strength of association. For all statistical significant tests, the cut-off value was set at P<0.05. Results In this study, the overall magnitude of any cytopenia, anemia, leucopenia and thrombocytopenia were 63.4%, 43.5%, 24.4% and 18.7%, respectively. In multivariate logistic regression analysis, severe immunosuppression and WHO clinical stage IV HIV disease were significantly associated with increased prevalence of cytopenias. In addition, older age and younger age showed significant association with increased prevalence of anemia and leucopenia, respectively. Conclusion Frequent occurrence of cytopenias was independently associated with severe immunosuppression and WHO clinical stage IV HIV disease. Further longitudinal multicenter studies are recommended to bolster the findings of this study in order to suggest the need of routine assessment and management of hematological abnormalities for optimal choice of initial antiretroviral agents and prevention of further morbidities.

Abstract
INTRODUCTION Few studies have examined cytopaenia among HIV positive pregnant women. OBJECTIVES To assess burden of cytopaenia among HIV positive pregnant women. METHODOLOGY This cross-sectional study of women on HAART ≤6months, defined anemia as hematocrit <33%, leucopenia as total white blood cell count <3,000 cells/mm3 and thrombocytopenia as absolute platelet count <100,000 cells/mm3. Univariate and bivariate analyses were performed. RESULTS Over 8 years, of 1,197 women, the mean age was 29.02(±5.4) years and mean gestational age 25.9(±8.1) weeks. Prevalence of anaemia was 76.8%, leucopaenia 6.9% and thrombocytopenia 4.7%. The mean haematocrit was 28.5%(±4.5); median white blood count 5,500/mm3 ; median platelet count 200,000/mm3 and median CD4 323 cells/mm3. Mean haematocrit was highest (29.7%±5.3) in women in the first trimester but lowest (28.4% ±4.6) in women in second trimester (p=0.04). Compared with earlier trimesters, women in the third trimester had higher median white blood count (5,600 cells/mm3), higher neutrophil (61.0% ±11.2) but lower lymphocytes (28.3%± 9.2) (p=0.18; 0.00, 0.00). Median absolute platelet count was highest (206,000 cells/mm3) in the first trimester but lowest (195,000 cells/mm3) in third trimester (0.04). Women with lower CD4 had higher prevalence of cytopaenias. CONCLUSION Cytopaenias are not uncommon in this population especially with lower CD4.

Abstract
Aim/objective To assess the common hematological abnormalities among HIV-antiretroviral therapy (ART) naïve clients attending an immune suppression syndrome (ISS) clinic at Mbarara Regional Referral Hospital (MRRH), southwestern Uganda. Patients and methods This was a cross-sectional study carried out during the months of March to August 2016 at the ISS clinic of MRRH. We collected approximately 4.0 mL of EDTA anticoagulated blood samples, which were assayed for complete blood count, CD4+ cell count and thin film examination. Correlation of the hematological abnormalities with CD4+ cell counts was done using correlation coefficient (r) and analysis of variance (F), and the p-value was set at ≤0.05. Results A total of 141 clients were enrolled. Of these, 67.38% (95/141) were anemic, 26.24% (40/141) had thrombocytopenia while 26.95% (38/141) had leucopenia. Of the 95 participants with anemia, 89.47% (85/95) presented with normocytic-normochromic anemia, 8.42% (8/95) with microcytic-hypochromic anemia and 2.11% (2/95) with macrocytic-hypochromic anemia. Anemia was not different across the several World Health Organization (WHO) stages of HIV infection disease progression (p>0.05). Statistically significant differences were present among participants with leucopenia (p<0.05). Also, leucopenia was more prevalent (11/38) among participants in WHO stage 4 of HIV infection. CD4+ cell counts correlated with thrombocytopenia (r=0.24, p<0.05) and leucopenia (r=0.15, p<0.05). Conclusion People living with HIV/AIDS (PLWHIV/AIDS) ought to be routinely monitored and treated for the occurrence of hematological abnormalities. Early initiation of ART can help to prevent some hematological abnormalities.

Abstract
Background Hematological abnormalities are common in HIV positive patients. Of these, thrombocytopenia is a known complication which has been associated with a variety of bleeding disorders. However, its magnitude and related factors have not been well-characterized in the era of highly active antiretroviral therapy (HAART) in Ethiopia. Therefore, this study aimed to assess the prevalence of thrombocytopenia before and after initiation of HAART among HIV positive patients attending Black Lion Specialized Hospital, Addis Ababa, Ethiopia. Methods A cross sectional study was conducted from February to April 2017 in Black Lion Specialized Hospital, Addis Ababa, Ethiopia. A total of 176 patients on HAART were selected using simple random sampling techniques. Socio-demographic and clinical characteristics of the study patients were collected using structured questionnaire. Measurements of platelet counts and CD4 + T cell counts were made using Sysmex XT 2000i hematology analyzer and BD FACS Count CD4 analyzer, respectively. Statistical analysis of the data (Paired T- test and binary logistic regression) was done using SPSS version 20. P-value < 0.05 was considered as statistically significant. Results A total of 176 patients (Age > 18 years old) were enrolled in this study and had a mean age of 40.08 ± 9.38 years. There was significant increase in the mean values of platelet counts (218.44 ± 106.6 × 103/μl vs 273.65 ± 83.8 × 103/μl, p < 0.001) after six months of HAART initiation compared to the baseline. Prevalence of thrombocytopenia before and after HAART initiation was 25 and 5.7% respectively. HIV patients whose CD4 counts < 200 Cells/μl were more likely to have thrombocytopenia than HIV patients whose CD4 count ≥350 Cells/μl. However, it was not statistically associated with prevalence of thrombocytopenia. Conclusions This study has shown that the prevalence of thrombocytopenia after HAART initiation was decreased significantly. Based on our results, a number of study participants still had thrombocytopenia after initiation of HAART. Therefore, continuous screening for thrombocytopenia among HIV infected patients should be performed to decrease the risk of morbidity and mortality.

Abstract
Background Anemia is the most common hematological abnormality in Human immunodeficiency virus (HIV) positive patients and a significant predictor of its progression to AIDS or death. This study was aimed to assess the prevalence of anemia before and after initiation of antiretroviral therapy (ART) among HIV positive patients attending Black Lion Specialized Hospital, Addis Ababa, Ethiopia. Methods A cross sectional study was conducted from January to April, 2017 in Black Lion Specialized Hospital, Addis Ababa, Ethiopia. A total of 255 patients on ART were selected using simple random sampling techniques. Socio-demographic and clinical characteristics of the study subjects were collected using structured questionnaire. Measurements of complete blood cell counts and CD4 + T cell counts were made using Sysmex XT 2000i hematology analyzer and BD FACS Count CD4 analyzer, respectively. Statistical analysis of the data (Chi-square, paired T-test, logistic regression) was done using SPSS version 20. A p-value < 0.05 was considered as significant. Results Prevalence of anemia before and after ART initiation was 41.9 and 11.4% respectively. There are a significance differences in CD4 + T cell count, RBC count, hemoglobin values and RBC indices in HIV patients before and after ART initiation (p-value < 0.05). WHO clinical stages and CD4+ T cell counts were found to be associated with the prevalence of anemia before ART initiation. Among the total number of anemic cases, normocytic normochromic anemia was present in 71% of the cases before ART and in 58.6% of the cases after ART. The prevalence of macrocytic normochromic anemia before and after ART initiation was 4.7 and 27.6% respectively. Conclusions It is evident from this study that there is a remarkable reduction in the prevalence of anemia after ART initiation. However, a significant proportion of HIV patients remained anemic after 6 months of ART initiation suggesting the need for routine screening and proper treatment of anemia to mitigate its adverse effects.

Abstract
Background Anemia is common among people living with HIV infection and is frequently associated with poor quality of life and poor prognosis. It has been well described in antiretroviral naïve individuals and those on non-nucleoside reverse transcriptase inhibitor-based first line antiretroviral therapy (ART) regimens. However there is limited information on anemia for ART experienced individuals on protease inhibitor-based second line ART regimens in resource limited settings. Our objective was to describe the prevalence and risk factors of anemia in this ART experienced population in Malawi. Methods We conducted a cross-sectional study using routine facility data at two HIV clinics in Lilongwe, Malawi. The analysis included individuals receiving protease inhibitor-based second line ART. Clinical and laboratory data were collected at routine clinic visits. We used descriptive statistics, two-sample t-tests and multivariate logistic regression for data analysis. Results Three hundred seventy-seven records were included in this analysis (37% male, median age 41 years, median CD4 count 415 cells/μL). The prevalence of anemia was 125/377 (33.2%) − mild, moderate and severe anemia was 17.5%, 13.8%, and 1.9% respectively. Female participants had a higher prevalence than male participants (43.6% vs. 15.7%, p < 0.001). In multivariate logistic regression, female sex (adjusted odds ratio (aOR) 5.3; 95% CI 2.9–9.5) and a CD4 count <200 cell/ul (aOR 3.1; 95%CI 1.6–6.0) were associated with increased risk of having anemia while a BMI ≥30 kg/m2 (aOR 0.8; 95% CI 0.6–1.0) and being on ART for more than 10 years (aOR 0.4; 95% CI 0.2–0.9) were associated with reduced risk of anemia. Being on a zidovudine- containing ART regimen was not associated with anemia. Conclusion Anemia is common in people on second line ART in Lilongwe, Malawi. Screening for anemia in this population would be a useful strategy; especially for female patients, those who are underweight and have a low CD4 cell counts.

Abstract
BACKGROUND HIV/AIDS causes high morbidity and mortality through both immunosuppression and complications not directly related to immunosuppression. Haematological abnormalities, including various cytopenias, occur commonly in HIV through immune and non-immune pathways. Though these complications could potentially cause serious clinical implications, published literature on the magnitude of this problem and its associated factors in Tanzania is scarce. This study aimed at determining the prevalence and risk factors of HIV-associated cytopenias among ART-naive patients enrolling for care and treatment services at Bugando Care and Treatment Centre (CTC) in Mwanza, Tanzania. METHODS This was a cross-sectional clinic-based study done between March 2015 and February 2016, involving all antiretroviral therapy (ART)-naive adult HIV-positive patients enrolling for care and treatment services at Bugando CTC. Patients younger than 18 years and those with missing data were excluded. Data were analysed using Stata version 11 to determine the prevalence and risk factors of cytopenias. RESULTS A total of 1205 ART-naive patients were included. Median age was 41 years (interquartile range [IQR] 32 to 48). Most participants were female (n = 789; 65.6%), with a female-to-male ratio of 2:1. The median baseline CD4 count was 200 cells/µL (IQR 113 to 439). About half (49%) of the study participants had baseline CD4 counts less than 200 cells/µL. Anaemia, leucopenia, and thrombocytopenia were found in 704 (58.4%), 285 (23.6%), and 174 (14.4%) participants, respectively, and these were strongly associated with advanced HIV infection. CONCLUSIONS The magnitude of cytopenias is high among ART-naive HIV-positive adults, and cytopenias are more marked with advanced HIV infection. Early diagnosis of HIV and timely initiation of ART could potentially reduce the number of people living with advanced HIV disease and its associated complications, including the cytopenias investigated in this study. Patients with cytopenias should undergo thorough screening for tuberculosis, which is an important and treatable correlate of cytopenia, in addition to close follow-up for any potential negative outcomes.

Abstract
INTRODUCTION There are few studies on the hematologic parameters of HIV-infected individuals in Ethiopia; of these, almost all studies researched adults. Our current study is unique in that it mainly focused on the pediatric population and compared both pre- and post-antiretroviral therapy (ART) children. Inference from this study can be used for other developing countries where the burden of HIV disease is high. OBJECTIVE The aim of this study was to identify hematologic abnormalities in HIV-infected children before and after initiation of ART. METHODOLOGY A cross-sectional study was conducted on HIV-infected children from June 1 to August 30, 2015. Data were collected using a pretested and structured questionnaire. Statistical analysis was performed using SPSS 20 version. RESULTS The median age of study subjects was 10 years with an interquartile range (IQR) of (6, 12). Two-thirds (74.3%) of study subjects received ART for >1 year. The median of CD4 count before ART was 490 cells/mm3 with an IQR of (286, 765); this increased to 663 cells mm3 with an IQR of (499, 908) after ART. Likewise, the median of hemoglobin before ART was 11.5 mg/dL with an IQR of (9.9, 13), which increased after ART to 13 mg/dL with an IQR of (11.8, 14). The prevalence of anemia was 42.8% before and 18.9% after ART initiation. The median of absolute neutrophil count before ART was 3×103 with an IQR of (2.1, 4.6) and after ART, it became 3×103 with IQR of (1.9, 4.2). Age <5 years (adjusted odds ratio [AOR]: 2.76; 95% CI: 1.5, 5.0), an advanced stage of AIDS (AOR: 2.8; 95% CI: 1.4, 5.6) and CD4% <25% (AOR: 2.4; 95% CI: 1.2, 4.9) were significantly associated with anemia before ART initiation, while opportunistic infections were associated with anemia after initiation of ART (AOR: 2.3; 95% CI: 1.08, 4.8). CONCLUSION ART positively or negatively affects the hematologic profile of HIV-infected children. The current study demonstrated a significant reduction of anemia after initiation of ART.

Abstract
BACKGROUND Acute kidney injury (AKI) is commonly associated with HIV infection. OBJECTIVES To describe the profile of AKI in HIV infected versus non-infected persons. PATIENTS AND METHODS This is a prospective study that was carried out during the study period from January 2010 to December 2015 in the department of nephrology-internal medicine D of Treichville University Hospital (Côte d'Ivoire). RESULTS The prevalence of HIV infection was 35.2% in the population of AKI. The average age of patients was 42±18 years in the HIV positive group against 51±18 years in the HIV negative group (P=0.0001). Etiologies were infections in 65.1% in the HIV positive group against 38.8% in the HIV negative group (P=0.0001) and water loss in 24.7% in the HIV positive group against 7.8% in the HIV negative group (P=0.0001). Factors such as the AIDS stage (P=0.002), severe sepsis (P=0.002) and acute pyelonephritis (P=0.001) were associated with mortality in HIV positive patients against severe anemia (P=0.0001) and severe sepsis (P=0.0001) in the HIV-negative group. CONCLUSION HIV positive patients are younger with a female predominance. The mortality rate is identical in both groups.

Abstract
Background Anemia is a major public health problem in HIV patients around the world. It has a negative effect on the quality of life of HIV patients and progression of the HIV disease. In the sub-Saharan African setting, including Ethiopia where both HIV infection and under-nutrition are expected to be high, there is a paucity of data on the matter. This study was aimed to reveal the magnitude and factors associated with anemia among adult HIV patients in Debre-Tabor Hospital, northwest Ethiopia. Methods A hospital-based cross-sectional study was used among adult HIV patients in Debre-Tabor Hospital from April 1 to May 30, 2015. The diagnosis of anemia was made following the 2011 World Health Organization recommendation on hemoglobin cut-off points. Univariable and multivariable logistic regression was carried out to assess factors associated with anemia. Results A total of 377 patients’ charts were reviewed. Most of the participants (n=237, 62.9%) were taking antiretroviral treatment (ART). The overall prevalence of anemia was 23% (95% CI: 19.1, 27.6). Being ART-naïve (adjusted odds ratio [AOR]: 3.37; 95% CI: 1.59, 7.14), having treatment history with anti-tuberculosis (TB) drug (AOR: 3.2; 95% CI: 1.19, 8.67), taking zidovudine (ZDV)-containing ART regimen (AOR: 2.14; 95% CI: 1.03, 4.57), and having recent CD4+ T-lymphocytes count of <200 cells/μL (AOR: 2.13; 95% CI: 1.04, 4.36) were associated with occurrence of anemia among adult HIV patients. Conclusion and recommendation Anemia continues to be a major co-morbidity among adult HIV patients in Ethiopia. Adult HIV patients who are taking ZDV-containing ART, with a history of TB treatment, have a low CD4+T-lymphocytes count and are ART-naïve should be carefully screened and treated for anemia.

Abstract
BACKGROUND Malaria and human immunodeficiency virus are the two most devastating global health problems causing more than two million deaths each year. Hematological abnormalities such as anemia, thrombocytopenia and leucopenia are the common complications in malaria and HIV co-infected individuals. The aim of this study was to determine the effect of malaria infection on hematological profiles of people living with HIV attending Gambella Hospital ART clinic, Southwestern Ethiopia. OBJECTIVE To determine the effect of malaria infection on hematological profiles of people living with HIV attending Gambella Hospital ART clinic, Southwestern Ethiopia. METHODS A facility based comparative cross-sectional study was conducted from May 25 to November 11, 2014 in Gambella Hospital. A total of 172 adult people living with HIV (86 malaria infected and 86 malaria non-infected) participants were included in the study. Demographic, anthropometric and clinical data were collected. Venous blood samples and stool specimen were collected for laboratory analysis. Microscopic examination of peripheral blood films was done for detection of malaria parasites. Descriptive statistics, student T- test, bivariable and multivariable analyses were performed using SPSS V-20. Statistical significance was set at p < 0.05. RESULTS A total of 172 adult people living with HIV were included in the study. The prevalence of anemia, thrombocytopenia and leucopenia in malaria and HIV co-infected participants were 60.5%, 59.3%, and 43.0%, respectively. Resident (AOR: 4.67; 95% CI: 1.44, 15.14), malaria infection (AOR: 2.42; 95% CI: 1.16, 5.04) and CD4 + count were predictors for anemia. A predictor for thrombocytopenia was malaria infection (AOR: 9.79; 95% CI: 4.33, 22.17). Malaria parasitic density (AOR: 0.13; 95% CI: 0.03, 0.57) and CD4 + count (AOR: 4.77; 95% CI: 1.23, 18.45) were predictors of leucopenia. CONCLUSIONS Findings suggest that the prevalence of anemia and thrombocytopenia were significantly higher in the malaria and HIV coinfected participants than the HIV mono-infected participants. Mean values of hematological profiles were significantly different in the two groups. Future prospective studies with larger sample size from other settings are needed to substantiate the findings.

Abstract
Anemia is one of the most important complications of HIV infection. In China, the prevalence, risk factors, and association between anemia and prognosis in HIV-infected patients are poorly elucidated. We analyzed data from 3452 HIV-infected patients not yet on combined antiretroviral therapy (cART) attending Beijing Ditan Hospital from June, 2003 to December, 2015. The overall prevalence of anemia was 9.8% (7.6% mild, 1.9% moderate, and 0.2% severe anemia). Female sex (odds ratio [OR] = 3.71, 95% confidence interval [CI]: 1.46-6.51, p = 0.003), age 40-59 years (OR = 2.54, 95% CI: 1.59-4.05, p < 0.001), body mass index < 18.5 kg/m2 (OR = 2.23, 95% CI: 1.31-3.79, p = 0.003), baseline HIV RNA CI: 1.32-5.99, p = 0.007) were risk factors for anemia. Age 40-59 years (adjusted hazard ratio [AHR] = 5.76, 95% CI: 1.62-20.55, p = 0.007), and anemia ‒ mild (AHR = 7.46, 95% CI: 1.48-37.50, p = 0.015), moderate (AHR = 9.89, CI: 1.35-72.38, p = 0.024), and severe (AHR = 28.29, 95% CI: 2.75-290.54, p = 0.005) anemia ‒ were associated with an increased hazard of death. In this cohort, mild anemia was most common. Anemia was associated with female sex, older age, lower body mass index, lower baseline CD4 count, and higher viral load. Moreover, anemia was associated with an increased risk of death. These findings should promote awareness among physicians to make a timely diagnosis of HIV and to help physicians prioritize prevention and intervention strategies for anemia in HIV-infected patients.

Abstract
We conducted a cross-sectional study to determine the prevalence and risk factors of leukopenia and thrombocytopenia among Chinese adults with newly diagnosed HIV/AIDS. One thousand nine hundred and forty-eight newly diagnosed HIV-infected patients were enrolled between 2009 and 2010. Serum samples obtained from each individual were collected for complete blood count. Factors associated with the presence of leukopenia and thrombocytopenia were analyzed by multiple logistic regression. The overall prevalence of leukopenia and of thrombocytopenia was 33.2% and 15.6%, respectively. The prevalence of leukopenia was higher among females than among males (39.4% versus 31.2%). The prevalence of leukopenia increased with decreasing CD4 count (8.2%, 26.5%, 33.4%, and 41.5% among patients with CD4 count of ≥ 350, 200-349, 50-199, and < 50 cells/mm3 respectively). The prevalence of thrombocytopenia also showed an increasing trend with decreasing CD4 count (5.8%, 12.2%, 17.8%, and 17.5% among patients with CD4 count of ≥ 350, 200-349, 50-199, and < 50 cells/mm3, respectively). Logistic analysis showed that female sex, lower CD4 count, and Han ethnicity were significantly associated with an increased risk of leukopenia, and that lower CD4 count, and HIV transmission by blood were significantly associated with an increased risk of thrombocytopenia. The study reflects that leukopenia and thrombocytopenia are common among Chinese adults with newly diagnosed HIV/AIDS; and lower CD4 count is associated with an increased risk of both leukopenia and thrombocytopenia. We propose that a routine assessment of these parameters is necessary for timely and adequate clinical management.

Profile of HIV-Infected Hispanics with Pancytopenia. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2015; 13:ijerph13010038. [PMID: 26703689 PMCID: PMC4730429 DOI: 10.3390/ijerph13010038] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/15/2015] [Revised: 10/27/2015] [Accepted: 11/05/2015] [Indexed: 12/18/2022]
Abstract
Pancytopenia is seen in late HIV infection; it is associated with medical complications and with decreased survival. We determined the prevalence of pancytopenia at baseline in a cohort of HIV-positive Hispanics living in Puerto Rico, and compared their socio-demographic, immunological and clinical characteristics. A total of 1202 patients enrolled between 2000 and 2010 were included. They were grouped according to pancytopenia status, defined by having: platelets <150,000 μL, white cell count <4000 μL, and hemoglobin <12 g/dL (women) or <13 g/dL (men). Differences were evaluated using Student's t-test, Chi-square test and Kaplan-Meier method. The prevalence of pancytopenia was 8.7%. Patients with pancytopenia had lower BMI and lower CD4 count, as well as higher HIV viral load and higher proportions of unemployment, clinical AIDS and antiretroviral treatment (ART) use (p < 0.05). One-year mortality rate was significantly higher in patients with pancytopenia (18.1% vs. 5.1%, p < 0.001). When stratifying for ART this association persisted for patients who did not receive ART (41.4% vs. 5.2%, p < 0.001), but it was not seen in patients who received treatment (9.2% vs. 5.6%, p = 0.196). Pancytopenia was associated with elements of advanced stages of HIV. ART could reduce the mortality of HIV-patients with pancytopenia to levels comparable to patients without the disorders.

Abstract
Early in the human immunodeficiency virus (HIV) epidemic, infected patients presented to medical attention with striking abnormalities in each of the major blood cell lineages. The reasons for these derangements remain complex and multifactorial. HIV infects multipotent haematopoietic progenitor cells and establish latent cellular reservoirs, disturbs the bone marrow microenvironment and also causes immune dysregulation. These events lead to cytokine imbalances and disruption of other factors required for normal haematopoiesis. Activation of the reticulo-endothelial system can also result in increased blood cell destruction. The deleterious effects of medications, including first and second generation anti-retroviral agents, on haematopoiesis were well documented in the early years of HIV care; in the current era of HIV-care, the advent of newer and less toxic anti-retroviral drugs have had a more beneficial impact on haematopoiesis. Due to impaired regulation of the immune system and potential side effects of one or more anti-retroviral agents, there is also an increase in coagulation abnormalities such as thromboembolism, and less frequently, acquired disorders of coagulation including thrombotic thrombocytopenic purpura, immune thrombocytopenic purpura and acquired inhibitors of coagulation. In this article we review the epidemiology and aetiology of select non-oncological haematological disorders commonly seen in people living with HIV-acquired immune deficiency syndrome.

Abstract
Background Ethiopia is one of the most seriously HIV affected countries in Sub-Saharan Africa. Anemia is a known predictor of disease progression and death among HIV infected patients. In this study, we investigated the magnitude and correlates of anemia among HIV infected patients receiving HAART at a referral hospital in Ethiopia. Methods A retrospective cohort study was conducted from November 2011 to February 2012 in Zewditu Memorial Hospital, Addis Ababa, Ethiopia. Records of 1061 patients on HAART were selected using simple random sampling technique. Socio-demographic and clinical characteristics of the study patients were collected using standardized data extraction instrument. Data were analyzed using STATA version 11.0. Odds ratios with 95% confidence intervals were used to quantify the strength of association between anemia and its potential predictors. Results The prevalence of anemia at baseline was 42.9%. However, the prevalence significantly decreased to 20.9% at 6 months (p < 0.001) and to 14.3% at 12 months (p = 0.001) after HAART initiation. At baseline, male sex (AOR = 1.55; 95% CI: 1.18-2.03), clinical stage III/IV (AOR = 2.03; 95% CI: 1.45-2.83) and TB co-infection (AOR = 1.52; 95% CI: 1.08-2.13) were independently associated with the odds of being anemic. After 6 months of HAART, male sex (AOR = 1.59; 95% CI: 1.13-2.23), baseline anemia (AOR = 2.38; 95% CI: 1.71-3.33) and TDF-based HAART (AOR = 2.87; 95% CI: 1.80-4.60) were independently associated with the odds of being anemic. Besides, anemia was independently associated with older age at 6 months. After 12 months of HAART, baseline anemia (AOR = 2.01; 95% CI: 1.36-2.97), age group 25–34 years (AOR = 5.92; 95% CI: 1.39-25.15), age group 45–54 years (AOR = 4.78; 95% CI: 1.07-21.36), CD4 count below 200 cells/mm3 (AOR = 2.15; 95% CI: 1.21-3.82) and 200–350 cells/mm3 (AOR = 1.91; 95% CI: 1.13-3.25) were independently associated with the odds of being anemic. Conclusions Although a remarkable reduction in the prevalence of anemia was observed following initiation of HAART, a significant proportion of HIV patients remained anemic after 12 months of HAART suggesting the need for routine screening and proper treatment of anemia to mitigate its adverse effects.

Abstract
Aims/objectives We aimed to determine the prevalence and correlates of thrombocytopenia among people living with human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) and to assess occurrence of antiplatelet antibodies, among thrombocytopenic HIV clients at Mbarara Regional Referral Hospital, southwestern Uganda. Materials and methods This was a retrospective review of hematologic results at enrollment to HIV care from 2005 to 2013. The prevalence and correlates of thrombocytopenia were estimated based on the Immune Suppressed Syndrome (ISS) Clinic electronic database. A cross-sectional study determined the occurrence of antiplatelet antibodies, using the monoclonal antibody-specific immobilization of platelet antigens (MAIPA) technique. Results We reviewed 15,030 client records. The median age was 35.0 (range 18–78; interquartile range [IQR] 28–42) years, and there were 63.2% (n=9,500) females. The overall prevalence of thrombocytopenia was 17.4% (95% confidence interval [CI]: 16.8%–18.0%). The prevalence of thrombocytopenia was 17.8% (95% CI: 17.1%–18.4%) among antiretroviral therapy (ART)-naïve clients (n=2,675) and was 13.0% (95% CI: 0.3%–21.9%) for clients who were on ART (n=6). The study found a significant association between thrombocytopenia and other cytopenias, CD4 counts, ART, and deteriorating HIV stage (P<0.05). Two of the 40 participants (5.0%) had antiplatelet antibodies. Conclusion This study has showed a high prevalence of HIV-related thrombocytopenia. Antiplatelet antibodies were found in 5.0% of HIV-infected thrombocytopenic participants. Our study shows a significant association of thrombocytopenia burden in a high-HIV study population (Southwest Uganda); therefore, there is need to monitor platelet counts and initiate platelet transfusion in our blood banking practices, to avert possible risks of bleeding.
