RESUMO

BACKGROUND: Malaria affects the intravascular environment, leading to abnormal coagulation activation, prolonged prothrombin time, and activated partial thromboplastin time. Despite the high prevalence of malaria in the study area, there has been little published research on the effects of Plasmodium infection on coagulation parameters. OBJECTIVE: The aim was to assess the effect of malaria on basic coagulation parameters among patients attending Dembia Primary Hospital and Makisegnit Health Center. METHODS: A cross-sectional study was carried out from January to March 2020. The study involved 120 participants. Blood specimens were collected, which were analyzed using a Huma Clot Due Plus analyzer. The collected data were entered into EpiData and exported to SPSS version 21 for analysis. Non-parametric statistical methods were employed to analyze the data. The results were considered statistically significant if the p-value was less than 0.05. RESULTS: Individuals infected with Plasmodium exhibit coagulation disorders with elevated levels of PT (Prothrombin Time), APTT (Activated Partial Thromboplastin Time), and INR (International Normalization Ratio) in comparison to healthy controls. The median PT, APTT, and INR values for infected cases were measured at 20.5 [8.6], 39.5 [17.9], and 1.8 [0.9], respectively, while healthy controls had measurements of 15.1 [2.5], 28.8 [8.3], and 1.3 [0.2] (p ≤ 0.001). The severity of coagulation disorders increased with an increase in parasitemia levels. The type of Plasmodium species present had a significant impact on PT and INR values (p ≤ 0.001), whereas APTT did not show any significant impact across the Plasmodium species (p > 0.05). CONCLUSION: The results of this study found that malaria has a substantial impact on various blood clotting parameters, including PT, APTT, and INR. Parasitemia severity is significantly associated with extended PT and INR, implying that the higher the parasitemia, the longer it takes for blood to clot. Furthermore, the study discovered that the PT and INR levels differed based on the type of Plasmodium species responsible for the infection.

RESUMO

BACKGROUND: Children in refugee camps, due to their living conditions, are the most vulnerable groups to suffer from anemia. Nutritional deficiencies, especially iron deficiency is the most common causes of anemia. However, there is limited information on the prevalence and associated factors of anemia in Ethiopia. Hence, this study aimed to assess the prevalence and associated factors of anemia among internally displaced children at Debark refugee camp, Northwest Ethiopia. METHODS: A cross-sectional study was conducted on 354 internally displaced children, at Debark refugee camp from March to May 2022. A systematic sampling technique was employed. The socio demographic characteristics were collected by using structured questionnaire via face-to-face interview with the caregivers. The hemoglobin level was determined using HemoCue301+. Form anemic children, venous blood sample was collected for iron profile analysis. Parasitological and anthropometric measurements were also done. The data were entered using Epi-data version 4.6.0.6 and exported to STATA version 14 for analysis. Bi-variable and multivariable binary logistic regression analysis were done. Both crude odds ratio and adjusted odds ratio with the corresponding 95% confidence interval were calculated to measure the strength of association. P-Value < 0.05 was considered as statistically significant association. RESULTS: From the total of 354 children included in this study, more than half (54.8%) of them were male. The median age of children was 7 years with interquartile range of (4-10) years. The total prevalence of anemia in this study was 33.62% (95% CI:28.7, 38.7). Moderate type anemia was predominant in this study. From anemic children 30 (25.2%) had iron deficiency anemia. In this study, low dietary diversity (AOR = 4.9; 95% CI: 2.0, 11.7), duration in the camp more than six months (AOR = 4.2; 95% CI:1.9, 9.4), presence of diarrhea (AOR = 2.7; 95% CI:1.3, 5.7), fever (AOR = 3.4; 95% CI:1.6, 7.1), and wasting (AOR = 3.6; 95% CI:1.3, 10.3) were significantly associated with the prevalence of anemia. CONCLUSION: Anemia was moderate public health problem in the current study. Focused policies and strategies towards to internally displaced children should be designed to reduce anemia, by preventing the significant risk factors associated with anemia.

RESUMO

BACKGROUND: Liver disease is any condition that affects the liver cells and their function. It is directly linked to coagulation disorders since most coagulation factors are produced by the liver. Therefore, this study aimed to assess the magnitude and associated factors of coagulation abnormalities among liver disease patients. METHODS: A cross-sectional study was conducted from August to October 2022 among 307 consecutively selected study participants at the University of Gondar Comprehensive Specialized Hospital. Sociodemographic and clinical data were collected using a structured questionnaire and data extraction sheet, respectively. About 2.7 mL of venous blood were collected and analyzed by the Genrui CA51 coagulation analyzer. Data were entered into Epi-data and exported to STATA version 14 software for analysis. The finding was described in terms of frequencies and proportions. Factors associated with coagulation abnormalities were analyzed by bivariable and multivariable logistic regression. RESULT: In this study, a total of 307 study participants were included. Of them the magnitude of prolonged Prothrombin Time (PT) and Activated Partial Thromboplastin Time (APTT) were 68.08% and 63.51%, respectively. The presence of anaemia (AOR = 2.97, 95% CI: 1.26, 7.03), a lack of a vegetable feeding habit (AOR = 2.98, 95% CI: 1.42, 6.24), no history of blood transfusion (AOR = 3.72, 95% CI: 1.78, 7.78), and lack of physical exercise (AOR = 3.23, 95% CI: 1.60, 6.52) were significantly associated with prolonged PT. While the presence of anaemia (AOR = 3.02; 95% CI: 1.34, 6.76), lack of vegetable feeding habit (AOR = 2.64; 95% CI: 1.34, 5.20), no history of blood transfusion (AOR = 2.28; 95% CI: 1.09, 4.79), and a lack of physical exercise (AOR = 2.35; 95% CI: 1.16, 4.78) were significantly associated with abnormal APTT. CONCLUSION: Patients with liver disease had substantial coagulation problems. Being anemic, having a transfusion history, lack of physical activity, and lack of vegetables showed significant association with coagulopathy. Therefore, early detection and management of coagulation abnormalities in liver disease patients are critical.

RESUMO

BACKGROUND: Asthma is a diverse disease with various etiologic bases. Severe asthma can be associated with increased mortality, hospitalization, and decreased quality of life for asthma patients. High blood eosinophil counts were associated with severe asthma, but recent studies have failed to confirm this as a marker of severe asthma among adult asthma patients. As a result, the purpose of this study was to determine the association between the severity of asthma and high blood eosinophil count. METHODOLOGY: A simple random sampling technique was used to select 291 asthmatic patients for an institution-based cross-sectional study. Socio-demographic, behavioral, and clinical characteristics were collected by using a pre-tested structured questionnaire. Four milliliters of venous blood were collected from asthmatic patients for complete blood count and peripheral morphology assessment. The eosinophil count was analyzed by the Unicel DxH 800 (Beckman Coulter, Ireland) analyzer. A statistical package for social science version 20 (SPSS) software was used to analyze the data. The non-parametric (Mann-Whitney U) test was used to compare the eosinophil count with different background variables. A binary logistic regression analysis was used to assess the factors associated with eosinophilia. A p-value less than 0.05 in multivariable logistic regression analysis was considered statistically significant. RESULT: In this study, the overall magnitude of eosinophilia was 19.6% (95% CI = 14.8-24.1). Being admitted to the emergency department (AOR = 0.25; 95% CI: 0.09-0.69, p = 0.007) and being female (AOR = 0.49; 95% CI: 0.26-0.9, p = 0.025) were shown to have a statistically significant association with eosinophilia. Moreover, the absolute eosinophil count was significantly higher among asthmatic patients infected with intestinal parasitic infection (p < 0.045). CONCLUSION: Being female and admission to the emergency department were negatively associated with eosinophilia. Lack of eosinophilia can be related to the low-T2 asthma phenotype. The absolute eosinophil counts were higher among intestinal parasite-infected patients. Therefore, different biomarkers will be considered for the proper diagnosis and management of adult asthma patients.

RESUMO

BACKGROUND: Automated hematology analyzers deliver accurate and reliable hemoglobin measurement but they are expensive to afford for most of the developing countries like Ethiopia. Point of care hemoglobin analyzer like HemoCue301+ has potential to alleviate such problems. The main aim of this study was to compare the hemoglobin concentration measured by HemoCue301+ with the Sysmex KX-21N method at University of Gondar Com-prehensive Specialized Hospital, Gondar, Ethiopia, 2020. METHODS: A hospital based cross-sectional study with convenient sampling technique was employed from November to December 2020. Institutional ethics approval was obtained prior to sample utilization. A total of 147 specimens were analyzed by HemoCue301+ and Sysmex KX-21N hematology analyzer to compare the hemoglobin concentration measured by the two methods. Paired sample t-test and Bland-Altman plot were used to arrive at conclusions. SPSS version 20 and MedCalc software were used for analysis of the data. RESULTS: The paired sample t-test indicated the mean difference of the two measurements was 0.08299 with a standard deviation of 0.82332 and t-test: 1.222 at 146 degrees of freedom. There was no significant difference between the two measurements with a p-value of 0.224. The concordance correlation coefficient of the two methods was 0.956 (95% CI: 0.940 - 0.968, p < 0.0001). From the Bland-Altman plot, the limit of agreement was -1.50 - 1.70 g/dL with the mean difference of 0.08299 (95% CI: -0.05121 - 0.2172). CONCLUSIONS: There was no significant difference in the hemoglobin measurement by the HemoCue and Sysmex KX-21N (coef = -0.127, 95% CI: -0.379 - 0.634). The HemoCue301+ may be used interchangeably with Sysmex-KX-21N automated hematology analyzers.

RESUMO

BACKGROUND: Immune hemolytic anemia commonly affects human immune deficiency infected individuals. Among anemic HIV patients in Africa, the burden of IHA due to autoantibody was ranged from 2.34 to 3.06 due to drug was 43.4%. IHA due to autoimmune is potentially a fatal complication of HIV which accompanies the greatest percent from acquired hemolytic anemia. OBJECTIVE: The main aim of this study was to determine the magnitude and associated factors of immune hemolytic anemia among human immuno deficiency virus infected adults at university of Gondar comprehensive specialized hospital north west Ethiopia from March to April 2021. METHODS: An institution-based cross-sectional study was conducted on 358 human immunodeficiency virus-infected adults selected by systematic random sampling at the University of Gondar comprehensive specialized hospital from March to April 2021. Data for socio-demography, dietary and clinical data were collected by structured pretested questionnaire. Five ml of venous blood was drawn from each participant and analyzed by Unicel DHX 800 hematology analyzer, blood film examination and antihuman globulin test were performed to diagnosis of immune hemolytic anemia. Data was entered into Epidata version 4.6 and analyzed by STATA version 14. Descriptive statistics were computed and firth penalized logistic regression was used to identify predictors. P value less than 0.005 interpreted as significant. RESULT: The overall prevalence of immune hemolytic anemia was 2.8% (10 of 358 participants). Of these 5 were males and 7 were in the 31 to 50 year age group. Among individuals with immune hemolytic anemia, 40% mild and 60% moderate anemia. The factors that showed association were family history of anemia (AOR 8.30 at 95% CI 1.56, 44.12), not eating meat (AOR 7.39 at 95% CI 1.25, 45.0), and high viral load 6.94 at 95% CI (1.13, 42.6). CONCLUSION AND RECOMMENDATION: Immune hemolytic anemia is less frequent condition in human immunodeficiency virus infected adults, and moderate anemia was common in this population. The prevalence was increased with a high viral load, a family history of anemia, and not eating meat. In these patients, early detection and treatment of immune hemolytic anemia is necessary.

RESUMO

BACKGROUND: Breast cancer is the most frequent and fatal cancer type globally. The fatality rate of breast cancer is mostly due to disease complications like hematological alterations. Therefore, this study aimed to assess the hematological abnormalities before, during, and after the initiation of cancer treatment in breast cancer patients at the University of Gondar comprehensive specialized hospital. METHODOLOGY: Hematological profiles were collected from 267 breast cancer patients who attended the cancer treatment center from September 2017 to August 2021. A data extraction sheet was used to extract data from the patient's medical chart, including sociodemography, clinical, and hematological profiles. EPI info version 3.5.1 and SPSS Version 25 softwares were used for data entrance and analysis, respectively. Descriptive statistics were summarized using frequency and percentage. The Friedman test followed by a Wilcoxon signed rank test was used to compare the mean difference between the hematological profiles at zero and after the 4th and 8th cycles of treatment. RESULT: Of the total participants, 91% were females, and the median age of the study participants was 45 (IQR = 36, 55) years. Red blood cell, white blood cell, and lymphocyte counts, as well as hematocrit and hemoglobin values, were significantly reduced after the initiation of cancer treatment, while the platelet count and red cell distribution width were significantly increased. The prevalence of anemia was 21.7% (95% CI: 16.6, 26.8), 22.7% (95% CI: 17.6, 27.8), and 26.4% (95% CI: 21.3, 31.5) before, during, and after the initiation of cancer treatment, respectively. The prevalence of leukopenia before, during, and after treatment was 9.7%, 18.8%, and 15.1%, respectively. Finally the prevalence of thrombocytopenia was 6.3%, 3.4%, and 8% at before, during, and after treatment, respectively. CONCLUSION: This study concluded that many hematological parameters were significantly affected by the breast cancer treatment. Therefore, proper patient follow-up and provide appropriate interventions related to their hematological abnormalities is crucial. It is also important to conduct further prospective studies to confirm the findings of this study.

RESUMO

BACKGROUND: Neonatal sepsis is one of the leading causes of neonatal morbidity and mortality in developing countries like Ethiopia. The investigation of neonatal sepsis needs the application of inclusive diagnostic tools. Therefore, this study aimed to assess the role of CBC parameters in diagnosing neonatal sepsis. METHODS: A comparative cross-sectional study was conducted from September 2020 to November 2021 at the University of Gondar Comprehensive Specialized Hospital. A total of 250 neonates were included using a convenient sampling technique. A structured questionnaire and a data collection sheet were used to obtain the socio-demographic and clinical characteristics of the study participants. A venous blood sample was collected for CBC and blood culture tests. Epi-Info Version 7 and SPSS Version 25 were used for data entry and analysis, respectively. The data distribution was checked by the Shapiro-Wilk test. Then, an independent t-test was conducted to compare CBC parameters, and the significant parameters were recruited for the ROC curves analysis. The Younden index test was used to determine the cutoff point for the sensitivity and specificity. A p-value of <0.05 was considered statistically significant. RESULTS: Out of 250 study participants, 144 (57.6%) were males, with a median age of 6 days (IQR = 4 days). Early-onset and late-onset sepsis were developed in about 29.6% (37/250) and 70.4% (88/250) of the neonates, respectively. The TLC and ANC parameters were significantly lower in cases than in control groups. The TLC, Hgb, lymphocyte count, and ANC parameters have a sensitivity of 64.8, 68, 33.6, and 49.6%, respectively. Their specificity in the diagnosis of neonatal sepsis was 64.8, 53.6, 83.2, and 90.4%, respectively. CONCLUSION: Total leucocyte count, ANC, and platelet count all showed significant associations with neonatal sepsis. Besides, the TLC, ANC, and platelet counts had good sensitivity and specificity in diagnosing neonatal sepsis. Therefore, these parameters can be used as a diagnostic tool for neonatal sepsis in resource-limited areas.

RESUMO

BACKGROUND: Asthma is a chronic inflammatory disease that affects the lungs. Variation in whole blood cell lines is caused by the progression and severity of asthma. Common hematological abnormalities encountered during asthma include eosinophilia, neutrophilia, leukocytosis, and increased erythrocyte sedimentation rate. The main aim of this study was to assess the selected hematological abnormalities and their associated factors among asthmatic patients in Northwest Ethiopia from March to May 2021. METHODOLOGY: A hospital-based cross-sectional study was conducted on a total of 320 asthmatic patients in Northwest Ethiopia. A simple random sampling technique was employed to select study participants. A pre-tested structured questionnaire and a checklist were used to collect data. Blood samples were collected from asthmatic patients for complete blood count and erythrocyte sedimentation rate determination. Hematological profiles were analyzed by Unicel DxH 800 (Beckman Coulter, Ireland). The erythrocyte sedimentation rate was determined by using the Westergren method. The data were entered into EpiData version 3.0.4 and analyzed with a statistical package for social science version 20 software. The bi-variable and multi-variable binary logistic regression models were used to assess the factors associated with hematological abnormalities. A p value of less than 0.05 in the multivariable logistic regression analysis was considered statistically significant. RESULTS: The overall prevalence of neutrophilia, eosinophilia, thrombocytopenia, leukocytosis, and basophilia was 35.3%, 20%, 11.9%, 10.3%, and 4.1%, respectively. Neutrophilia was associated with a lack of physical activity (AOR = 3.25; 95% CI 1.43-7.37) and a history of taking non-asthmatic drugs within the previous three months (AOR = 2.63; 95% CI 1.22-5.65). Being admitted to the emergency department (AOR = 0.27; 95% CI 0.11-5.67) was found to be associated with eosinophilia. In addition, being admitted to the emergency department (AOR = 5.44; 95%CI: 2.6-11.3) was associated with thrombocytopenia. CONCLUSION: The current study demonstrated the predominant prevalence of neutrophilia, followed by eosinophilia, among asthma patients. Therefore, hematological abnormalities should be taken into account for proper monitoring and management of asthmatic patients.

RESUMO

BACKGROUND: Knowledge of the ABO and RhD group distribution is essential for blood banks inventory and assuring quality blood transfusion services. The objective of this study was to determine the frequency of ABO and RhD phenotype, allele, and genotype among blood donors at North Gondar District Blood Bank from 2010 to 2012, Northwest Ethiopia. METHODS: The data of the current study were obtained from registration logbooks of blood donors registered. The ABO and RhD grouping was done by using commercially available monoclonal antibodies (anti-A, anti-B and anti-D) by slide methods. Results with no agglutination by anti-D antibody were confirmed using anti-human globulin test. Descriptive statistics were analyzed using SPSS version 20. The allele and genotype frequency of the donors was determined by Hardy-Weinberg equilibrium assumption. The difference between the observed and expected frequency was tested by online Chi-square calculator. P-value of <0.05 was considered statistically significant. RESULTS: Among 6471 blood donors, 82.1%, 94.1% and 55.4% were males, replacement donors and in the age group of 21-30 years, respectively. Blood group O (47.04%) and blood group AB (4.81%) were the dominant and least common, respectively. The distribution of the RhD negative blood group was 5.76%. The distribution of A, B and O alleles was 0.1714, 0.1433 and 0.6859, respectively. Moreover, the genotype frequency of AA, AO, BB, BO, AB and OO was 0.0294, 0.2350, 0.0205, 0.1966, 0.0491 and 0.4704, respectively. The genotype frequency of DD, Dd and dd was 0.5774, 0.3649 and 0.0576, respectively. The result showed that there was no statistically significant difference between observed and expected allele and genotype frequency (P-value >0.05). CONCLUSION: Blood group O and AB were the most and least prevalent, respectively. The allele and genotype frequency of the population was fulfilled the Hardy-Weinberg equilibrium assumption. This finding might be useful for blood transfusion services.

RESUMO

BACKGROUND: Anemia is an adverse outcome and common complication in chronic kidney disease patients. This is usually associated with iron deficiency, inflammation and blood loss. However, little is known about the prevalence of anemia and its predictors among chronic kidney disease patients in Southern Ethiopia. This study aimed to determine anemia and its predictors among adult non-dialysis chronic kidney disease patients in Southern Ethiopia. METHODS: A cross-sectional study was conducted on 384 chronic kidney disease patients from February to April 2019. Socio-demographic and clinical data were collected using questionnaires and medical records. Adjusted hemoglobin was taken to define anemia using the level of Hgb <13 mg/dL for males and <12 mg/dL for females; and blood films and serum ferritin were done for anemic participants. SPSS version 25.0 was used for data analysis. Frequency distribution tables and graphs were used to describe descriptive statistics. A bivariate logistic regression model was used to determine the predictors; p <.05 was considered statistically significant. RESULTS: Overall prevalence of anemia was 44.0% (95% CI: 39.0%, 48.9%); of which 7.1%, 62.1% and 30.8% of anemic patients had mild, moderate and severe anemia, respectively. The prevalence of anemia increased from 20.6% in stage 2 to 100% in stage 5. Morphologically, normocytic normochromic anemia was the most predominant type. Cardiovascular disease (AOR = 2.37, 95% CI: 1.35, 4.16), diabetes mellitus (AOR = 2.77, 95% CI: 1.08, 7.14), stage 3b chronic kidney disease (AOR = 2.74, 95% CI: 1.31, 5.73) and stage 4 and 5 chronic kidney disease patients (AOR = 7.11, 95% CI: 3.22, 15.72) showed significant association with anemia. CONCLUSION: Anemia was a severe public health problem and associated with cardiovascular disease, diabetes mellitus and stages of chronic kidney disease. Thus, early diagnosis, treatment and prevention of anemia are recommended.

RESUMO

BACKGROUND: Transfusion transmissible infections (TTIs) remain a major public health problem in developing countries including Ethiopia. In Ethiopia, comprehensive information about sero-epidemiology of major TTIs is lacking at the national level. Therefore, this systematic review and meta-analysis was aimed at providing the pooled estimate of human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV) and syphilis among blood donors in Ethiopia. METHODS: Relevant studies published until May 31, 2019 were searched through PubMed/Medline, EMBASE, SCOPUS, HINARI, Cochrane database library, Web of Science, Google Scholar and Google. The methodological quality of articles was assessed using Joanna Brigg's Institute critical appraisal checklist for prevalence and analytical studies. The pooled sero-epidemiology of HIV, HBV, HCV and syphilis were determined using the random-effects model. Heterogeneity between the studies was assessed using the I2 statistics. Publication bias was assessed by visual inspection of the funnel plot and Egger's statistics. RESULTS: A total of 7921 articles were retrieved, and 7798 were screened for eligibility after duplicates removed. Forty-nine full-text articles were assessed for eligibility; of which 45 were eligible for qualitative and quantitative synthesis: categorized as 36, 34, 31 and 23 studies for estimations of HBV, HIV, HCV and syphilis, respectively. In the random-effects model, the pooled sero-epidemiology of HBV, HIV, HCV and syphilis was 5.20, 2.83, 0.93 and 1.50%, respectively. Moreover, being a male blood donor was significantly associated with HBV and syphilis infection, whereas being a replacement blood donor was significantly associated with a high burden of HIV, HBV and HCV infections. CONCLUSION: The pooled sero-epidemiology of major TTIs among blood donors was high. Therefore, there is a need to design prevention and control strategies in a comprehensive approach to reduce the burden.

RESUMO

BACKGROUND: Erythropoiesis stimulating agents are exogenous erythropoietin medications that are used to stimulate the bone marrow red blood cells' production for the management of anemia of chronic kidney disease, some anticancer drugs, myelodysplastic syndrome, and others. Currently, there are different erythropoiesis stimulating agents accessible in the market. The objective of this narrative literature review is to summarize the role of some erythropoiesis stimulating agents in the treatment of anemia. METHODS: The following method was used to prepare this narrative literature review. The comprehensive computerized search of literatures was carried out using PubMed, Cochrane library, Google scholar, and Science direct. Keywords such as recombinant human erythropoietin, epoetin, darbepoetin, continuous erythropoietin receptor agonist, pegzyrepoetin alfa, erythropoiesis stimulating agents in combination with anemia/anaemia were used. The pertinent original and review full articles which are written in the English language were included in this narrative review. RESULTS: From the discussions of the literature, erythropoiesis stimulating agents that are produced by different biosimilar manufacturers have different clinical characteristics and stabilities as a result of their chemical modifications. The chemical modifications of erythropoiesis stimulating agents like glycosylation and polyethylene glycosylation determine the half-life, affinity to erythropoietin receptor, and immune response of the agents. Erythro-poiesis stimulating agents are categorized as short-acting and long-acting agents due to their chemical structures that influence the clinical efficacy and safety of the agents. CONCLUSIONS: The effectiveness of the agents is different in different patients depending on the individual characteristics and etiologies of anemia. The agents not only have the benefits but also, they have the risks for the patients. Hence, the risks and benefits of erythropoiesis stimulating agents must be given special consideration in the managements of anemia to get maximum efficacy for anemic patients. The treatment is dependent on hemoglobin levels of individual patients. The physician must follow the patients during and after therapy using erythropoiesis stimulating agents.

RESUMO

BACKGROUND: Isolated or multi lineage cytopenia are the most common clinicopathological features and independently associated with increased risk of disease progression and death among human immunodeficiency virus infected children. In the study area, there is scarcity of data about the magnitude of various cytopenia. OBJECTIVES: Aimed to determine the magnitude and associated factors of peripheral cytopenia among HIV infected children at the University of Gondar Specialized Referral Hospital ART clinic, Northwest Ethiopia. METHODS: Institutional based cross-sectional study was conducted on 255 HIV infected children from January- April 2020. None probable convenient sampling technique was used to select the study participant. Socio demographic data were collected by pre tested structured questionnaire via face-to-face interview and their medical data were obtained from their follow-up medical records. Moreover, blood specimens were collected and examined for complete blood count, viral load and blood film, whereas stool specimens were collected and examined for intestinal parasites. Bi-variable and multi-variable logistic regression models were fitted to identify associated factors of cytopenia. P-Value <0.05 was considered as statistically significant. RESULT: The overall magnitude of peripheral cytopenia was 38.9%. Anemia, leukopenia, lymphopenia, thrombocytopenia and bi-cytopenia were 21.2%, 12.2%, 11%, 1.6% and 3.9% respectively. Being in the age group of 2-10 years (AOR = 5.38, 95%CI 2.33-12.46), AZT based regimen (AOR = 5.44, 95%CI: 2.24-13.21), no eating green vegetables (AOR = 2.49, 95% CI: 1.26-4.92) and having plasma viral load >1000 copies /ml (AOR = 5.38, 95%CI: 2.22-13.03) showed significant association with anemia. CONCLUSION: Anemia was the predominant peripheral cytopenia among HIV infected children in this study. It was strongly associated with AZT based drug type, age below 10 years and high viral load. Critical stress should be given for early investigation and management of cytopenia in addition to the use of alternative drug which leads to higher viral suppression and lower risk of toxicity issue.

RESUMO

BACKGROUND: Human immunodeficiency virus (HIV) and intestinal parasites co-infections are the most common causes of clinical illness and death, especially for children living in resource constrained setting. Therefore, the aim of this study was to determine the prevalence and associated factors of intestinal parasites among highly active anti-retroviral therapy (HAART) initiated children. METHODS: Cross-sectional study was conducted among 255 HAART initiated HIV-infected children at the University of Gondar Comprehensive Specialized Hospital from January to April 2020. Socio-demographic characteristics were collected using a structured questionnaire via a face-to-face interview. Clinical data of the children were collected by reviewing the medical records. Venous blood was collected for complete blood counts, viral load determination, and blood film examination. Flotation concentration technique was done in addition to direct wet mount for parasitological examination. Bi-variable and multi-variable logistic regression analysis were used to check the presence of significant association, and P-value<0.05 was considered as statistically significant. RESULTS: The overall prevalence of intestinal parasite infection (IPI) among the study participants was 22.4% (95% CI=17-28%). The presence of opportunistic infection (AOR=2.09 95% CI=1.81-5.43), no eating under-cooked animal products (AOR=0.38 95% CI=0.16-0.94), male sex (AOR=0.45 95% CI=0.22-0.90), viral load rate >1,000 copies/mL (AOR=1.80 95% CI=1.67-4.19), and cytopenia (AOR=2.71 95% CI=1.59-12.25) showed significant association with the prevalence of IPI. CONCLUSION: Entamoeba histolytica and Ascaris lumbricoides were the most prevalent intestinal parasites among HAART initiated children. Among HAART initiated children, IPI were associated with gender, cytopenia, viral load, undercooked animal products, and the presence of opportunistic infections. Therefore, health education, prompt treatment, and regular deworming should be implemented to alleviate the burden of intestinal parasites in HIV-infected children.

RESUMO

Purpose: Platelet parameter alteration such as platelet count and platelet indices are more common than in other blood cell lines due to diverse causative pathophysiological mechanisms in severe malaria infection. In malaria patients, no more studies evaluated platelet indices in relation to disease severity and prognosis. Therefore, this review assessed the current scientific knowledge on the potential role of platelet indices for the diagnostic marker of severe malaria infection. Results: Hence, after reviewing recent literatures, elevation of mean platelet volume and platelet distribution width in addition to decreased plateletcrit and platelet counts is the known potential risk factor associated with warning signs of severe malaria. Thus, thrombocytopenia < 150 × 109/L, MPV ≥ 9.05 fL, and PDW ≥ 14.550% as well as significantly higher P-LCR and decrease in PCT are shown significant sensitivity and specificity as they are used as diagnostic and prognostic values in severe malaria infection. Conclusion: Platelet indices are useful predictors of malaria severity. Immature platelet fraction (IPF%) is raised in the case of severe malaria, and it was significantly more useful than MPV. Advanced research will further investigate the platelet index abnormality associated with specific age and gender among specific malaria species.

RESUMO

BACKGROUND: Globally, anemia affects one-fourth of the world population including 30% of nonpregnant reproductive-aged women. It has a number of causes including micronutrient deficiencies and chronic infections, inherited or acquired disorders of hemoglobin synthesis and red blood cell production, or survival alterations. The aim of this study was to assess the prevalence and associated factors of anemia among reproductive-aged women in Sayint Adjibar town, South Wollo Zone, Northeast Ethiopia. METHODS: A community-based cross-sectional study was conducted from February to April among 359 reproductive-aged women (RAW). Systematic random sampling technique was implemented to select study participants. Sociodemographic, socioeconomic, and reproductive histories of study participants were collected using the structured and pretested questionnaire. Capillary blood and stool samples were collected from each study participant for hemoglobin and parasitological analysis, respectively. Data were entered into Epi Info version 7 and transferred to SPSS version 20 for analysis. Both bivariable and multivariable binary logistic regression models were fitted to identify associated factors of anemia. p value <0.05 was considered as statistically significant. RESULT: The median age of the study participants was 25 years. The overall prevalence of anemia was 24.2%. Among those anemic individuals, 49 (56.3%) were mildly anemic. Age category 36-49 years (AOR = 2.64; 95% CI: 1.05, 6.60), no formal educational status (AOR = 2.28; 95% CI: 1.06, 4.92), food insecurity (AOR = 1.92; 95% CI: 1.01-3.65), and body mass index of above 25 kg/m2 (AOR = 0.27; 95% CI: 0.08-0.87) were found to be statistically significant with anemia. CONCLUSION: The prevalence of anemia in this study was found as a moderate public health problem. The prevalence was significantly associated with women who had no formal education and were of older age group and those women living with household food insecurity and with higher body mass index. Therefore, it is better to design appropriate interventional strategies to reduce reproductive-aged women anemia. These include information, education, and communication activities focused on reproductive-aged women with no formal education and life-cycle-focused food security rather than targeted to only infants and young children or pregnant women.

RESUMO

INTRODUCTION: Acute transfusion reactions are adverse events occurring within 24 hrs of transfusion and cause simple-to-severe complications. They may vary with the blood component transfused and recipient factors. In Ethiopia, there is a limited evidence about the incidence and associated factors of transfusion reactions. OBJECTIVE: To determine the proportion of acute transfusion reactions and associated factors among adult transfused patients. METHODS: A total of 384 study participants were included in the study. Structured questionnaires were used for socio-demographic and past medical history data collection. Vital signs were measured as a baseline for every study participants and monitored and followed for 24 hrs. Laboratory tests like complete blood count, direct anti-human globulin test and urine hemoglobin were done as a baseline for suspected patients. Cross-match, blood grouping, and blood culture for patients and donors sample were also done for suspected patients. Descriptive statistics, bivariable and multivariable binary logistic regression were analyzed using SPSS version 20. P-value of <0.05 in the multivariable model was considered as statistically significant. RESULTS: Acute transfusion reactions were observed in 5.2% of patients. Of total cases of acute transfusion reaction, the majority developed allergic reactions (65%) and febrile non-hemolytic transfusion reaction (30%). It was significantly associated with transfusion history (AOR=3.4; 95% CI: 1.2-9.7), abortion history (AOR=5.0; 95% CI: 1.5-16.4), longer blood storage time (AOR=5.1; 95% CI: 1.7-15.2) and receiving three or more unit of blood (AOR= 4.1; 95% CI: 1.5-11.2). CONCLUSION: Acute transfusion reactions were observed in 5.2% of patients (allergic reactions (65%), febrile non-hemolytic transfusion reaction (30%) and alloimmunization (5%)). Patients with a history of transfusion, abortion, transfused with blood stored ≥14 days and multi-transfused patients should be closely monitored.

RESUMO

BACKGROUND: Tuberculosis (TB) and HV have been intertwined and makeup a deadly human syndemic worldwide, especially in developing countries like Ethiopia. Previous studies have reported different TB incidences and its association with CD4+ T cell counts among HIV positive patients in Ethiopia. Thus, the goal of this meta-analysis was, first, to determine pooled incident TB among adult HIV positive patients, and second, to assess the association between incident TB and baseline CD4+ T cell count strata's. METHODS: We searched PubMed, Cochrane library, Science Direct and Google scholar databases from June 1 to 30, 2018. The I2 statistics and Egger's regression test was used to determine heterogeneity and publication bias among included studies respectively. A random effects model was used to estimate pooled incident TB and odds ratio with the respective 95% confidence intervals using Stata version 11.0 statistical software. RESULTS: A total of 403 research articles were identified, and 10 studies were included in the meta-analysis. The pooled incident TB among adult HIV infected patients in Ethiopia was 16.58% (95% CI; 13.25-19.91%). Specifically, TB incidence in Pre-ART and ART was 17.16% (95% CI; 7.95-26.37%) and 16.24% (95% CI; 12.63-19.84%) respectively. Moreover, incident TB among ART receiving patients with baseline CD4+ T cell count < and > 200 cells/mm3 was 28.86% (95% CI; 18.73-38.98%) and 13.7% (95% CI; 1.41-25.98%) correspondingly. The odds of getting incident TB was 2.88 (95% CI; 1.55-5.35%) for patients with baseline CD4+ T cell count < 200 cells/mm3 compared to patients with baseline CD4+ T cell count > 200 cells/mm3. CONCLUSION: High incident TB among adult HIV positive patients was estimated, especially in patients with CD4+ T cell count < 200 cells/mm3. Therefore, Early HIV screening and ART initiation, as well as strict compliance with ART and increasing the coverage of TB preventive therapy to more risky groups are important to prevent the problem.

RESUMO

BACKGROUND: The diagnosis of iron deficiency anemia is still complicated and most of the tests have drawbacks. Bone marrow examination, the gold standard for the diagnosis of iron deficiency and iron deficiency anemia, is a painful, invasive, and costly procedure. Other methods are also used to diagnose iron deficiency and iron deficiency anemia; soluble transferrin receptor, serum iron, serum ferritin, and transferrin saturation are most common biomarkers of iron status that are frequently affected by inflammation, chronic diseases, and in the normal aging process (except soluble transferrin receptor). All are less available compared to complete blood count with reticulocyte hemoglobin content (CHr). Reticulocytes have a normal life span of one or two days in the circulation. CHr is a good indication of iron availability and an early marker of iron deficient erythropoiesis which can be obtained readily using automated blood cell analyzers. Therefore, the main objective of the current review is to assess the role of CHr for diagnosis of iron deficiency, iron deficiency anemia, and monitoring of iron therapy. METHODS: Studies published in English were searched using the National Library of Medicine, PubMed, and Google scholar databases. RESULTS: According to this review, CHr has a moderate sensitivity and specificity for diagnosing iron deficiency, and is less affected by inflammation than serum iron, transferrin saturation, and ferritin and is an early predictor of treatment response. It is used in screening of iron deficiency, diagnosis of iron deficiency anemia, and diagnosis of functional iron deficiency anemia in acute or chronic diseases or inflammation. CHr is also important in treatment monitoring. It is useful for early measurement of response to iron therapy, increasing within days of the initiation of iron therapy. It helps monitoring of intravenous iron supplementation, recombinant human erythropoie¬tin therapy, and oral iron therapy in hemodialysis and non-hemodialysis patients, and children. CONCLUSIONS: It is easy to analyze, less time consuming, and less expensive than bone iron examination and iron biochemical tests. However, there is no standardized cutoff point and different researchers use varying cutoff values which affects its accuracy in diagnosing iron deficiency and it should therefore be standardized. Moreover, since CHr can be affected with any conditions that cause iron restricted erythropoiesis, further analysis may be needed.
