Association between fetal hemoglobin, lactate dehydrogenase, and disease severity in patients with sickle cell disease at Bugando Medical Centre, Mwanza, Tanzania.

INTRODUCTION: There is a wide range of clinical manifestations in sickle cell disease (SCD). Despite having the same condition, each person's response to disease complications differs greatly. Individuals can be categorized according to the severity of their diseases to determine which group they fall into and receive the appropriate care based on their needs. The relationship between fetal hemoglobin (HbF), lactate dehydrogenase (LDH), and disease severity in Tanzania is little understood. This investigation sought to ascertain the relationship between HbF, LDH, and disease severity in SCD patients at the Bugando Medical Center. METHOD: This cross-sectional study was carried out on SCD patients aged 6 months and older at the Bugando Medical Center in Mwanza, Tanzania. A total of 130 SCD patients were enrolled. The clinical history and laboratory test results for SCD patients were recorded on a specially constructed patient report form. RESULTS: The majority of participants (56.9%) were men. For the population under study, more than half (60.8%) of participants had a moderate clinical phenotype (MCP), followed by 31.5% of asymptomatic participants and 7.7% of people with severe clinical phenotypes (SCP). Participants with SCP had substantially higher levels of LDH, with a mean level of 810.97IU/L (95% CI: 559.31-1062.64) and a p-value of 0.005. The severe clinical phenotype exhibited a significantly higher mean HbF score value of 10.09% (95% CI: 7.44-13.74%) with a p-value of 0.024 when compared to the asymptomatic and moderate clinical phenotypes. CONCLUSION: In SCD patients with SCP compared to ACP and MCP, the HbF levels were higher, but did not show a protective effects, and LDH can be used to predict the severity of SCD.

Anemia in HIV Patients Attending Highly Active Antiretroviral Therapy Clinic at Hoima Regional Referral Hospital: Prevalence, Morphological Classification, and Associated Factors.

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.

Association Between Helicobacter pylori Infection and Anemia Among Adult Dyspeptic Patients Attending Kiryandongo General Hospital, Uganda.

Purpose: To determine the prevalence of anemia and its association with Helicobacter pylori infection among adult dyspeptic patients. Patients and Methods: A cross-sectional study was conducted among 283 dyspeptic patients at Kiryandongo General Hospital, in Uganda. A structured questionnaire was administered to capture demographic and clinical characteristics of study participants. Four milliliters of blood were then collected into an EDTA vacutainer for Complete Blood Count (CBC) and analyzed using HUMA COUNT 30TS, and peripheral blood smears were made and stained using Giemsa stain. Anemia was defined as hemoglobin levels <12g/dl in females and <13g/dl in men according to the World Health Organization (WHO). Helicobacter pylori (H. pylori) stool antigen test was performed using Whole power H. pylori Ag rapid test device, and saline stool preparation was examined for intestinal parasites. Chi-squared test and Logistic regression were performed to determine association, and a p-value of ≤0.05 was considered statistically significant. Results: The overall prevalence of Helicobacter pylori infection was 42.4% (120/283). The prevalence of anemia among H. pylori-infected patients was 25.8% (31/120) and 15.3% (25/163) among H. pylori-negative counterparts. H. pylori infection was significantly associated with anemia (p-value 0.042), age (p-value 0.02, 0.009), water sources (p-value 0.0049,) and intestinal parasitic infestation (p-value 0.02), respectively. Conclusion: This study has shown that the prevalence of H. pylori infection and anemia is high among dyspeptic patients at Kiryandongo General Hospital. H. pylori infection was found associated with anemia, age, water sources, and intestinal parasitic infestation. Routine screening of anemia in H. pylori-infected individuals and further studies to explore the relationship between anemia and H. pylori disease is highly recommended.

Asymptomatic malaria infection, associated factors and accuracy of diagnostic tests in a historically high transmission setting in Northern Uganda.

BACKGROUND: Asymptomatic malaria infections are important parasite reservoirs and could sustain transmission in the population, but they are often unreported. A community-based survey was conducted to investigate the prevalence and factors associated with asymptomatic malaria infections in a historically high transmission setting in northern Uganda. METHODS: Using a cross-sectional design, 288 children aged 2-15 years were enrolled and tested for the presence of malaria parasites using rapid diagnostic tests (RDTs) and blood smear microscopy between January to May 2022. Statistical analysis was performed using the exact binomial and Fisher's exact test with p ≤ 0.05 indicating significance. The logistic regression was used to explore factors associated with asymptomatic malaria infections. RESULTS: Overall, the prevalence of asymptomatic infection was 34.7% (95% CI 29.2-40.5) with the highest observed in children 5-10 years 45.9% (95% CI 35.0-57.0). Gweri village accounted for 39.1% (95% CI 27.6-51.6) of malaria infections. Median parasite density was 1500 parasites/µl of blood. Plasmodium falciparum was the dominant species (86%) followed by Plasmodium malariae (5%). Factors associated with asymptomatic malaria infection were sleeping under mosquito net (Adjusted Odds Ratio (aOR) 0.27; 95% CI 0.13-0.56), p = 0.001 and presence of village health teams (VHTs) (aOR 0.02; 95% CI 0.01-0.45), p = 0.001. Sensitivity and specificity were higher for the P. falciparum/pLDH RDTs compared to HRP2-only RDTs, 90% (95% CI 86.5-93.5) and 95.2% (95% CI 92.8-97.7), p = 0.001, respectively. CONCLUSION: Asymptomatic malaria infections were present in the study population and this varied with place and person in the different age groups. Plasmodium falciparum was the dominant parasite species however the presence of P. malariae and Plasmodium ovale was observed, which may have implication for the choice and deployment of diagnostic tools. Individuals who slept under mosquito net or had presence of functional VHTs were less likely to have asymptomatic malaria infection. P.f/pLDH RDTs performed better than the routinely used HRP2 RDTs. In view of these findings, investigation and reporting of asymptomatic malaria reservoirs through community surveys is recommended for accurate disease burden estimate and better targeting of control.

Anaemia, Morphological Classification and Its Associated Risk Factors Among Lactating Mothers at Mbarara City Council Health Centre IV, Southwestern Uganda.

Purpose: The objectives of this study were to determine the prevalence of anaemia, morphological classification and its associated risk factors among the lactating mothers accessing postnatal care at Mbarara City Health Centre IV, Southwestern Uganda. Patients and Methods: A cross-sectional study was conducted at Mbarara City Health Centre IV among 264 participants. A structured questionnaire was used to capture characteristics of study participants. 4 mL of venous blood was collected from each participant for complete blood count (CBC) and peripheral blood smear (PBS). CBC was done using hematology analyzer (BC-2800 Mindray Hematology Analyzer) while PBS were taken for participants with hemoglobin (Hb) <12.0g/dl and stained using Giemsa-Maygrunwald stain. Bivariate analysis and multivariate logistic regression were used to determine the associations between factors and anaemia. A p-value of <0.05 was considered significant. Results: The overall prevalence of anaemia was 65 (24.6%), with mean hemoglobin (Hb) concentration of 12.5g/dL. Out of the anaemic participants (24.6%), morphological classifications of anaemia were as follows: normocytic normochromic 27 (41.5%), microcytic hypochromic 20 (30.8%), normocytic hypochromic 16 (24.1%) and macrocytic normochromic 2 (3.1%). According to the severity of anaemia, majority had mild anaemia 52 (80%), moderate anaemia was 11 (16.9%), and severe anaemia was 2 (3.1%). The following risk factors were significantly associated with anaemia: duration of lactation (between 5 to 8 months, p-value 0.017, 95% CI (0.12-0.82) and alcohol consumption (p-value 0.032, 95% CI (1.12-12.16). The rest of the variables had no association with anaemia. Conclusion: The prevalence of anaemia among lactating mothers is high and it is a moderate public health problem as defined by WHO. Nutrition promotion, and health education, may be the ideal way to reduce the prevalence of anaemia in this region.

Prevalence, Morphological Classification, And Factors Associated With Anemia Among Pregnant Women Accessing Antenatal Clinic At Itojo Hospital, South Western Uganda.

PURPOSE: The study aimed to determine the prevalence, morphological classification, and risk factors of anemia among pregnant mothers attending antenatal clinic at Itojo hospital, Ntungamo district, southwestern Uganda. PATIENTS AND METHODS: After obtaining an informed consent, 5mL of blood was collected from the vein of each participant for complete blood count (CBC) and peripheral film report. The CBC was performed using HumaCount 80 hematology analyzer (HUMAN Gesellschaft für Biochemica und Diagnostica mbH Max-Planck-Ring 21 65,205 Wiesbaden Germany). Peripheral blood smears were made and stained using Wright's Romanowsky stain and examined under ×1000 magnification for morphological classification of anemia. Structured questionnaires were administered to each participant to collect information on patients' demography and risk factors of anaemia in pregnancy. The data generated were prepared in EXCEL and later transferred to SPSS version 20 for analysis. Univariate logistic regression and multivariate logistic regression were used to evaluate the association of socio-demographic characteristics of the participants with anemia. A 95% confidence level was used and statistical significance was reached at p<0.05. RESULTS: One hundred and sixty-three participants (n=163) were recruited for the study with the median age of 25 years and range of (17 to 40 years). The overall prevalence of anemia was 12 (7.4%), the morphological classification was 1 (8.3%) normocytic normochromic anemia, 6 (50%) microcytic hypochromic anemia, and 5 (41.7%) macrocytic anemia. Spouse occupation (p=0.03), household income (p=0.04), use of insecticide-treated mosquito nets (p=0.001), history of urinary tract infection (p=0.002), use of haematinics (p≤0.001), and history of postpartum hemorrhage (p=0.03) were significantly associated with anemia in pregnancy. CONCLUSION: Despite the reported high prevalence of anemia in pregnancy in other areas within the country, anemia prevalence was low in this study. Routine screening for anemia at all antenatal care clinics countrywide is recommended.

Antimicrobial resistance in pathogenic aerobic bacteria causing surgical site infections in Mbarara regional referral hospital, Southwestern Uganda.

Surgical site infections (SSI) remain a common postoperative complication despite use of prophylactic antibiotics and other preventive measures, mainly due to increasing antimicrobial resistance. Here, we present antimicrobial resistance rate of bacteria isolated in clinical cases of SSI. A hospital based descriptive cross sectional study was conducted on 83 consented postoperative patients with clinical SSI. Data on patients was obtained using structured data collection form. Two swabs were collected aseptically from each patient. Bacteriological culture examination and identification was done following standard microbiological techniques. Antibiotic susceptibility test was done by Kirby-Bauer disc diffusion method. Gram negative bacteria (GNB) were predominant (65.59%) with the dominant being Klebsiella species (29.03%). Overall 86% of aerobic bacteria isolated were multidrug resistant (MDR) where 65.63% and 96.72% of Gram positive and Gram negative isolates were MDR respectively. All the isolates with exception of Enterococci species were resistant to ampicillin. GNB showed high resistance to ceftriaxone, sulfamethoxazole/trimethoprim and gentamicin. All the isolated Klebsiella spp were MDR. S. aureus were all resistant to oxacillin. The isolation rate was higher in emergency, males and dirty wounds in relation to nature of surgery, gender and class of surgical wound respectively. These findings necessitate judicious antibiotic use and calls for surveillance of SSIs periodically as well as strict adherence to good sanitation practice to reduce spread of drug-resistant pathogens.

Assessment of the quality of stored blood for transfusion at Mbarara Regional Referral Hospital, Southwestern Uganda.

Aim and objective: To assess the quality of blood stored for transfusion at Mbarara Regional Referral Hospital (MRRH) regarding bacterial contamination, malaria infection, and laboratory audit status. Materials and methods: Whole blood and packed red blood cells at MRRH were critically inspected for visual anomalies, and a portion of this blood was aseptically collected and analyzed for Plasmodium species and bacterial contamination using culture methods. For culture positive samples, drug susceptibility testing (DST) was done using the Kirby-Bauer disc diffusion method. An audit using Stepwise Laboratory quality Improvement Process Towards Accreditation (SLIPTA) quality checklist was conducted. The obtained data were analyzed as frequencies and proportions at 95% confidence interval (CI), and significance levels of relatedness were set at p-values<0.05. Results: Of the 202 samples analyzed, 6 (3%) had bacteria while 3 (1.5%) had Plasmodium falciparum trophozoites. The bacterial isolates were Staphylococcus aureus (N=4, 66.7%); Corynebacterium spp (N=1, 16.7%) and Micrococcus spp (N=1, 16.7%). Staphylococcus aureus showed sensitivity to chloramphenicol, oxacillin, amikacin, and gentamycin. Thirty (14.9%) of these units had visually detectable anomalies, and the laboratory audit score was 53.8%. Conclusion: The quality of some blood stored for transfusion at MRRH was inadequate, and the laboratory quality standard based on SLIPTA was low. Based on this, it is crucial to always insist on aseptic measures at all stages (phlebotomy, processing, transporting, and blood storage) and consider more assessment of the donor risk to minimize transfusion-transmitted malaria. It is plausible to standardize the hospital blood transfusion laboratory and revive hemovigilance by the hospital transfusion committee.

Prevalence and Risk Factors of Helicobacter pylori Infection among Children Aged 1 to 15 Years at Holy Innocents Children's Hospital, Mbarara, South Western Uganda.

BACKGROUND: Helicobacter pylori infection affects more than half of the world's population. The infection is generally acquired during childhood but can remain asymptomatic, with long-term clinical sequelae including gastritis, peptic ulcer disease, and stomach cancer. METHODS: The study was approved by Institutional Review Committee of Mbarara University of Science and Technology. After obtaining informed consent from parents/legal guardians, illegible children who presented with gastrointestinal complaints at Holy Innocents Children's Hospital were recruited; structured questionnaires were administered to the parents/guardians to collect information on sociodemographic data and risk factors of H. pylori infection. Four (4) millilitres of blood was collected from each child and tested for H. pylori blood Antibody test and stool specimens were used for H. pylori antigen test. RESULTS: The prevalence of H. pylori infection among the study participants was 24.3%. The infection rate increased with increase in age of the participants, from 16.2% among 1to 5 years old to 27.2% among 6 to 10 years. Infections were higher among school going children (68/74, p=0.003, OR 3.9; CI: 1.5 to 10.6) and children from crowded households (59/74, p<0.001, OR 2.6, and CI 1.3 to 5.0), unsafe source of drinking water at schools (46/74, p=0.003), and lack of sanitary facility at homes (57/74, p=0.001, and OR 1.6 CI 0.7 to 3.6). CONCLUSION: The prevalence of H. pylori infection among children aged 1 to 15 years at Holy Innocents Children's Hospital was high and increases with age. School attendance, lack of sanitary facility, lack of safe drinking water, and overcrowding were the risk factors associated with H. pylori infection.

Hematological abnormalities in HIV-antiretroviral therapy naïve clients as seen at an immune suppression syndrome clinic at Mbarara Regional Referral Hospital, southwestern Uganda.

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.

Biochemical changes in stored donor units: implications on the efficacy of blood transfusion.

BACKGROUND: Blood transfusion with allogeneic blood products is a common medical intervention to treat anemia or prepare patients for surgical procedures. Generally, the blood units are secured and stored prior to expected transfusion. During storage, a number of biochemical changes occur (generally known as storage lesion), which can affect the efficacy of blood transfusion. The aim of the study was to evaluate the biochemical changes that occur in blood units during storage and to project the impact of these changes on transfusion. METHODS: The study protocol was approved by the Faculty of Medicine Research Ethics committee of Mbarara University of Science and Technology. A total of 200 blood recipients were categorized into two study arms: group I received fresh blood (n=100) and group II received old blood (n=100), who were formally consented and recruited consecutively. A total of 2 mL of venous blood was collected from each participant in EDTA tubes before transfusion (for pre-transfusion hemoglobin [Hb] estimation) and after transfusion (for post-transfusion Hb estimation). Each crossmatched unit was sampled to collect plasma for pH, lactate and potassium assays. Data were analyzed with STATA version 12.0. RESULTS: A total of 200 blood transfusion recipients aged 1-60 years were enrolled in the study. Up to 60% of the participants were females. The pH of the stored blood dropped from 7.4 to 7.2 in the first 3 days to ~7.0 by day 11 and to <7.0 by day 35 (p=0.03). The average rise in lactate level was 25 g/dL in blood stored for 0 to 11 days and 32.4 g/dL in blood stored for 21-35 days. The highest increase was encountered in blood stored beyond 28 days: 40-57 g/dL by 35 days (p=0.001). Potassium levels equally increased from ~4.6 mmol/L in the first 5 days of storage to ~14.3 mmol/L by 11 days. From the third week of blood storage and beyond, there was exponential increase in potassium levels, with the highest record in blood units stored from 30 to 35 days (p=0.068). CONCLUSION: Whole blood stored for >14 days has reduced efficacy with increased markers of red cell storage lesion such as increased potassium level, lactate and fall in pH. These lesions increase the length of hospital stay.

Rhesus blood group haplotype frequencies among blood donors in southwestern Uganda.

AIM/OBJECTIVE: The study was undertaken to determine the Rhesus blood group system and Rhesus haplotype frequencies among blood donors at Mbarara Regional Blood Bank. MATERIALS AND METHODS: We included ethylene-diaminetetra-acetic acid-containing plasma samples and serum samples from recruited consented blood donors. The Rh blood group system and the Rh haplotypes was established by the incubation of appropriate antisera (anti-D, anti-E, anti-C, anti-e, and anti-c) and cells at a temperature of 24°C in microplates for 1 hour and the reaction was read by gentle shaking and examining for agglutinations. Donors were asked to fill in questionnaires, after we obtained the informed consent, to assess their demographics. RESULTS: Among the 386 participants, 233 were males (60%) and 153 (40%) females. The Rh negative blood group percentage was 3.8%, while the Rh haplotype frequencies were as follows: Dce dce 68.1%, dce dce 2.8%, CD. dce 13%, cDE dce 12.4%, DC. DcE 1.6%, DcE DcE 1%, dC. dce 0.8%, and DcE DC. 0.3%. CONCLUSION: Given this frequency, a high prevalence of anti-D alloantibody formation among those transfused is possible and could cause diverse effects, especially in the Rh D positive women. We recommend additional research studies on the role of autoimmunity to the transfused on the occurrence of Rh D variants plus their implications on hemolytic disease of the fetus and newborn in Uganda. This study recommends that the blood bank includes Rhesus haplotyping in its protocols and that the finding be disseminated to donors and blood users.

Occurrence of anti-D alloantibodies among pregnant women in Kasese District, Western Uganda.

OBJECTIVES: This study was undertaken to determine the distribution of ABO/RhD (rhesus D antigen) blood phenotypes, prevalence of anti-D alloantibodies, and the risk factors for alloimmunization among pregnant women in Kasese District, Western Uganda. MATERIALS AND METHODS: Ethylenediamine tetraacetic acid-containing plasma samples and serum samples were taken from pregnant women attending the antenatal clinic. The blood groups were identified using the microplate grouping method, while the presence of anti-D alloantibodies was detected by the indirect antiglobulin test (IAT). Data were also collected from the pregnant women on the risk factors associated with anti-D alloantibody formation. RESULTS: Among the 726 participants, the blood group distribution was as follows: O: 356 (49.%); A: 190 (26.%); B: 152 (21%); and AB: 28 (4%). A total of 28 (3.86%) pregnant women were RhD negative. Anti-D alloantibodies were detected in 88 (12.1%) of the participants; and of these, 13 (14.8%) were RhD negative. Statistically significant risk factors for anti-D alloimmunization included miscarriage, stillbirth, and postpartum hemorrhage. CONCLUSION: Blood group O was the most common among the pregnant women in this study and the prevalence of Rh negativity was 3.8%. The frequency of anti-D alloimmunization among pregnant women in Kasese District was 12.12%, with 85.5% of these being RhD positive. Risk factors such as a history of stillbirths, miscarriages, and incidence of postpartum hemorrhage were significantly associated with anti-D alloimmunization. There is a need to routinely carry out antenatal blood grouping and IAT screening on pregnant women in Uganda to detect anti-D alloimmunization. Given the high prevalence of anti-D alloantibody formation among RhD-positive women, we recommend additional research studies on the role of autoimmunity among antigen-positive women, as well as the occurrence of RhD variants plus their implications on hemolytic disease of the fetus and newborn, in Uganda.

Prevalence of HIV-related thrombocytopenia among clients at Mbarara Regional Referral Hospital, Mbarara, southwestern Uganda.

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.
