Exploring coagulation parameters as predictive biomarkers of Plasmodium infection: A comprehensive analysis of coagulation parameters.

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.

Effect of Malaria and Schistosoma mansoni Coinfection on Selected Biochemical Profiles among Patients Attending Selected Health Institutions at Dembiya, Northwest Ethiopia.

Background: Malaria and schistosomiasis are infectious diseases that cause biochemical abnormalities. Malaria and Schistosoma mansoni coinfection causes exacerbations of health consequences and comorbidities. The study area is found in Ethiopia, where coinfection of malaria and S. mansoni is common. However, there is limited data on the biochemical profiles of patients coinfected with malaria and S. mansoni schistosomiasis in the study area. Hence, this study aimed to assess the effect of malaria and S. mansoni schistosomiasis coinfection on selected biochemical profiles. Methods: An institutional-based comparative cross-sectional study was conducted from March 30 to August 10, 2022. Using a convenient sampling technique, 70 participants (35 cases and 35 controls) were enrolled in the study. Schistosoma mansoni was detected in stool samples using the wet mount and the Kato Katz method. To detect Plasmodium, both thick and thin blood films were prepared and stained with Giemsa. The blood sample was processed for the analysis of biochemical profiles. All data were analyzed using SPSS version 25. A p value of less than 0.05 was considered statistically significant. Results: The mean values of alanine aminotransferase and aspartate aminotransferase (37.1 U/L and 41.9 U/L, respectively) in coinfected participants were significantly higher than in the healthy control participants (17.4 U/L and 22.0 U/L, respectively) (p < 0.05). Also, the median values of creatinine, total bilirubin, and direct bilirubin (1.51 mg/dL, 2.35 mg/dL, and 0.91 mg/dL, respectively) in coinfected participants were significantly higher than in the healthy control participants (0.85 mg/dL, 0.42 mg/dL, and 0.12 mg/dL, respectively) (p < 0.05). However, median values of total protein (4.82 g/dL) and mean values of glucose (66.6 mg/dL) in coinfected participants were significantly lower than in the healthy control participants (total protein (7.64 g/dL) and glucose (91.9 mg/dL)) (p < 0.05). The results of biochemical profiles in healthy participants were significantly different from those with light, moderate, and heavy S. mansoni infection intensity in malaria and S. mansoni coinfection (p < 0.05). Schistosoma mansoni infection intensity had a positive correlation with biochemical profiles except for total protein and glucose, which correlated negatively in coinfected participants (p > 0.05). Conclusion: Biochemical profiles in coinfection were significantly changed as compared to healthy individuals. As a result, biochemical profile tests should be utilized to monitor and manage coinfection-related problems, as well as to reduce coinfection-related morbidity and death.

Plasmodium falciparum histidine-rich protein 2 and 3 genes deletion in global settings (2010-2021): a systematic review and meta-analysis.

BACKGROUND: The usefulness of histidine-rich protein-2/3 (HRP2/3)-based rapid diagnostic tests of malaria due to Plasmodium falciparum has been threatened by the appearance of mutant PfHRP2/3 genes. This study was undertaken to determine the global pooled estimates of PfHRP2/3gene deletions. METHODS: Relevant publications were identified from electronic databases such as; PubMed, EMBASE, and MEDLINE online. Besides, all the relevant literatures were retrieved through Google and Google Scholar. STATA software was used for data analysis. The pooled estimates were calculated using random effect model. The summary estimates were presented using forest plots and tables. RESULTS: A total of 27 studies were included in the systematic review. However, only 24 and 17 studies were included for PfHRP2 and 3 gene deletion meta-analysis, respectively. The prevalence of PfHRP2 gene deletion across the individual studies ranged from the highest 100% to the lowest 0%. However, the meta-analysis result showed that the global pooled prevalence of PfHRP2 and PfHRP3 gene deletions were 21.30% and 34.50%, respectively. The pooled proportion of PfHRP2 gene deletion among false negative PfHRP2-based RDTs results was found to be 41.10%. The gene deletion status was higher in South America and followed by Africa. The pooled estimate of PfHRP2 gene deletion among studies, which did not follow the WHO PfHRP2/3 gene deletion analysis protocol was higher than their counter parts (21.3% vs 10.5%). CONCLUSIONS: This review showed that there is a high pooled prevalence of PfHRP2/3 gene deletions in Plasmodium falciparum confirmed isolates and also a high proportion of their deletions among false-negative malaria cases using PfHRP2-based RDT results. Hence, malaria diagnosis based on PfHRP2-based rapid tests seems to be less sensitive and warrants further evaluation of PfHRP2/3 gene deletions.

The Prevalence of Malaria among Children in Ethiopia: A Systematic Review and Meta-Analysis.

BACKGROUND: Malaria is one of the most public health important and life-threatening parasitic infections caused by the protozoan parasite. Since children are immunologically naive to the malaria parasite, they are the main vulnerable groups. During malaria infection, they might have a complication of anemia, cerebral malaria, coma, respiratory distress, and a decrease in cognitive and behavioral improvement. Therefore, this review was aimed at determining the pooled prevalence of malaria among children in Ethiopia. METHODS: The current systematic review and meta-analysis were conducted based on the guideline of Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement guideline. Electronic bibliographic databases such as Google Scholar, PubMed, and Science Direct were used for searching relevant literature. Besides, the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI) was used for critical appraisal of studies. Using the STATA 14 software, the pooled Meta logistic regression was computed to present the pooled prevalence with a 95% confidence interval (CI). RESULT: The overall estimated pooled prevalence of malaria among children in Ethiopia was 9.07 (95% CI: 6.32, 11.82). Subgroup analysis based on malaria signs and symptoms showed that the pooled prevalence of malaria among asymptomatic and symptomatic children was 6.67% (95% CI: 0.36, 12.98) and 27.17% (95% CI: 18.59, 35.76), respectively. CONCLUSION: The findings revealed a high prevalence of malaria among children in Ethiopia. As a result, still there is a need of improving and rechecking the existing malaria prevention and control measures of the country.

Evaluation of Intestinal Parasite Infection in Low and High Coverage of Graduated Households, Northwest Ethiopia: A Comparative-Based Crosssectional Study.

Intestinal parasite infections are widely distributed and affect various segments of the population in Ethiopia as in many developing countries. The government launched an innovative program called Health Extension Program to increase the coverage of primary health care services, mainly by producing model households using model-family training. The aim of this study was to evaluate the intestinal parasite infection in low and high coverage of graduated households. Method. A community-based crosssectional study was conducted from February to June, 2019. A total of 478 participants were enrolled in this study by using a multistage sampling technique. Data were collected by using pretested and semistructured questionnaire. Five grams of stool specimen was collected, and samples were processed using a direct wet mount and Kato Katz technique. Data were coded, entered, and cleaned using statistical package for social science (SPSS) version 20. A Chi-square test was employed to compare the two groups. P value < 0.05 were taken as statistically significant. Result. The prevalence rate of IPIs was 39% and 20.5% in LCGHH and HCGHH, respectively. A. lumbricoides was the predominant parasite, detected in 14.6% and 8.8% followed by S. mansoni 6.3% and 2.1% in LCGHH and HCGHH districts, respectively. LCGHH had significantly higher prevalence of A. lumbricoides, S. mansoni, and hookworm infections than the HCGHH district (P < 0.05). Thirteen (18.8%) study participants in LCGHH and four (11.7%) in HCGHH showed heavy infection with the four common soil-transmitted helminths (A. lumbricoides, S. mansoni, hookworm, and T. trichiura). Among study participants who were positive for S. mansoni, 53.3% in LCGHH and 20% in HCGHH had heavy infection for the Kato thick smear used. Conclusion. The prevalence of IPIs is significantly higher in LCGHH than in the HCGHH district. Producing more model households by giving model family training to nonmodel households and strengthening the information, education, and communication package are crucial in the implementation of the HEP to decrease the prevalence of IPIs especially in LCGHH districts.

Evaluation of Hookworm Diagnosis Techniques from Patients in Debre Elias and Sanja Districts of the Amhara Region, Ethiopia.

BACKGROUND: Inappropriate diagnosis could intimidate the prevention and control of hookworm infection. Thus, this study was aimed at evaluating the performance of hookworm diagnosis methods. METHODS: An institution-based cross-sectional study was conducted from patients in Debre Elias and Sanja districts of the Amhara region, Ethiopia, from November 2019 to January 2020. The study subjects were selected conveniently. After the data was entered into Statistical Package for the Social Sciences (SPSS), sensitivity, specificity, predictive values, test accuracy, and agreement of the different hookworm diagnosis methods, namely, test tube flotation technique (TFT), McMaster (MM), formol-ether concentration (FEC), Kato-Katz (KK), and direct wet mount microscopy (DWMM), were calculated by using SPSS software. The composite reference standard (CRS) was used as the gold standard method. The kappa (κ) test was used to measure the level of agreement between diagnosis tests. RESULT: A total of 389 stool samples were collected from patients in the study. The overall prevalence of hookworm was 63.24%. The test tube flotation technique (TFT) was found to be the highest both in terms of sensitivity and diagnostic accuracy (100%). McMaster (MM) was the second most sensitive test (68.7%), followed by FEC (44.3%) and KK (38.2%). On the other hand, DWMM had the lowest sensitivity (37.4%), and its diagnostic accuracy was also the least (60%). Only TFT had a perfect agreement (agreement = 100%, kappa = 1) with the CRS. The sensitivity of DWMM, KK, and FEC showed a kind of linear function with the intensity of infection, but TFT and MM methods were not affected by the infection intensity. CONCLUSION: Hookworm is still a public health problem in the study area. TFT is by far more sensitive than MM, FEC, KK, and DWMM techniques.

Prevalence and Associated Factors of Intestinal Helminths Among Kindergarten Children in Gondar Town, Northwest Ethiopia.

BACKGROUND: Intestinal parasitic infections (IPIs) are small organisms that infect the gastro-intestinal tract of human beings. Causes malnutrition, iron deficiency anemia, impairment of physical and mental development in children. The aim of this study was to determine the prevalence of intestinal helminthiasis and associated factors among Kindergarten (KG) children in Gondar Town, northwest Ethiopia. METHODS: Institution-based cross-sectional study was conducted on 390 Kindergarten children in Gondar town, Northwest, Ethiopia from March to May 2019. Study subjects were selected using systematic random sampling method. Data were gathered through direct interview by using a pretested questionnaire. Stool specimens were collected and examined using Kato Katz technique. Chi square was used to assess the association between variables and p-value less than 0.05 was taken as a statistical significance. RESULTS: The overall prevalence of intestinal helminthiasis was 16.7%, while those of participants infected by soil-transmitted helminths (STHs) and intestinal Schistosomiasis were 13.8% and 5.9%, respectively. Ascaris lumbricoides was the predominant STHs (9%) followed by Trichuris trichiura (2.3%) and hookworm (1.5%). Light infection was observed in almost all of the infected study participants. Intestinal helminthiasis was found to be significantly associated with age, KG level of children, maternal occupation, and educational status of parents. CONCLUSION: A significant number of children were infected by intestinal parasites in the study area. A. lumbricoides and intestinal Schistosomiasis were the most predominant of the isolated parasites.

The Prevalence of Intestinal Parasites and Their Associated Factors among Diabetes Mellitus Patients at the University of Gondar Referral Hospital, Northwest Ethiopia.

BACKGROUND: Worldwide, more than one-sixth of the population is infected by intestinal parasites, of which the majority live in developing countries. On the other hand, the prevalence of diabetes mellitus has been increasing over recent decades in developing countries. Patients with diabetes mellitus encountered impaired immunity and suffer from the consequences of infection particularly intestinal parasitic infection. OBJECTIVE: This study is aimed at assessing the prevalence of intestinal parasites and associated factors among diabetes mellitus patients at the University of Gondar Referral Hospital, Northwest Ethiopia. METHODS AND MATERIALS: An institutional-based cross-sectional study was conducted at the University of Gondar Comprehensive Specialized Referral Hospital from February 15 to March 30, 2018. A total of 234 diabetes mellitus patients were enrolled. A systematic random sampling technique was used to select study participants. Sociodemographic and clinical data were collected using a semistructured questionnaire. A 5-gram stool sample was collected to identify parasitic infection using a direct wet mount and formal-ether concentration technique. Data was entered and analyzed by using SPSS version 20. A p value of ≤0.05 was considered as statistically significant. RESULT: In the current study, the overall prevalence of intestinal parasite infection among diabetics was 45 (19.2%). The parasites identified in this study were Ascaris lumbricoides 15 (6.41%), Entamoeba histolytica/dispar 9 (3.85%), Hookworm 9 (3.85%), Schistosoma mansoni 7 (3%), Enterobius vermicularis 3 (1.3%), and Giardia lamblia 2 (0.9%). Poor educational background (AOR = 3.62; 95% CI (1.038, 12.65); p = 0.043), poor hygiene and sanitation (AOR = 4.67; 95% CI (1.82, 12.07); p = 0.001), and inappropriate latrine usage (AOR = 5.41; 95% CI (1.43, 20.56); p = 0.013) were significantly associated with the prevalence of intestinal parasitic infection among diabetes mellitus patients. CONCLUSION: The overall prevalence of intestinal parasitic infection among diabetes mellitus patients was relatively high. There should be continued prevention, control, and management of intestinal parasitic infection in such a study population.

Prevalence, Intensity, and Associated Factors of Schistosoma mansoni among School Children in Northwest Ethiopia.

BACKGROUND: Schistosomiasis is one of the Neglected Tropical Diseases in Ethiopia, and its burden may show variations from time to time across different regions. Thus, this study was aimed at determining the prevalence, intensity, and associated risk factors of Schistosoma mansoni (S. mansoni) among schoolchildren in Northwest Ethiopia. METHODS: A school-based cross-sectional study was conducted. A multistage sampling technique was used to select the study participants. Stool specimens were collected and examined using two-slide Kato-Katz method. Data were analyzed using SPSS version 20 software. Multivariate logistic regression analysis was used to identify risk factors. p values less than 0.05 were taken as statistically significant. RESULT: A total of 786 schoolchildren were participated in this study. The prevalence of S. mansoni was 33.5%. The mean egg count of the parasite among the infected study participants was 523.665 eggs per gram (epg) of stool. Thirty-seven, 42, and 21 percent of the study participant's infection were due to light, moderate, and heavy infection intensities, respectively. Age of 8-11 years old (AOR = 1,687, 95%CI = 1.163, 2.892), 5th-8th grade level (AOR = 2.280, 95%CI = 1.348, 3.856), residing in Chuahit District (AOR = 95.559, 95%CI = 12.945, 705.419), and using untreated water for domestic supply (AOR = 1.724, 95%CI = 1.457, 2.148) were found to be risk factors for S. mansoni infection. CONCLUSION: High prevalence of S. mansoni and relatively higher proportion of moderate intensity of infection in this study imply that schistosomiasis is still one of the major public health problems in Northwest Ethiopia. It is also highlighted that study sites, provision of water supply, age, and grade level of the schoolchildren were identified as a risk factors for the disease.

Knowledge, Attitudes and Practices Toward Prevention and Early Detection of COVID-19 and Associated Factors Among Religious Clerics and Traditional Healers in Gondar Town, Northwest Ethiopia: A Community-Based Study.

BACKGROUND: COVID-19 control measures efforts are affected by the knowledge, attitudes, and practices of the public, particularly religious clerics and traditional healers, who have close contact and are widely accepted by a significant number of community members. METHODS: A community-based cross-sectional study was conducted to determine knowledge, attitudes and practices towards COVID-19 and its associated factors among religious clerics and traditional healers in Gondar town. Study participants who met our inclusion criteria were selected using a simple random sampling technique. Data were collected by trained data collectors through face-to-face interviews. The reliability of the questionnaire was assessed using Cronbach's alpha. Knowledge, attitudes and practices scores were calculated to give the overall knowledge, attitude and practice score. Binary logistic regression was fitted to identify associated factors and odds ratio was used to measure the strength of the association. RESULTS: A total of 410 religious clerics and traditional healers were included in the study with a response rate of 97.1%. Of the total participants, 60.7% (95%: CI (56-65%)) had good knowledge, 34.1% (95%: CI (30-39%)) had a positive attitude and 15.6% (95%: CI (12-19%)) had good practices towards prevention and early detection of COVID-19. Less than one third of the participants practiced physical distancing (28%) and facemask use (17.8%). In multivariate logistic regression, age, educational status and marital status were significantly associated with knowledge score. Likewise, age and marital status were significantly associated with the positive attitude score. In addition, age, educational status, and the presence of underlying disease were significantly associated with the good practice score. CONCLUSION: Majority of the participants had poor practice and negative attitudes. Therefore, there should be a sensitization program to fill the gap in the knowledge, attitudes and practice measures of COVID-19 especially for elderly and illiterates.

A 7-Year Trend of Malaria at Primary Health Facilities in Northwest Ethiopia.

BACKGROUND: Malaria is a severe parasitic disease that can progress to complications of the nervous system, respiratory distress, renal problems, metabolic acidosis, and hypoglycemia which can result in death in case of delay or absence of appropriate treatment. Even though health service facilities and vector control strategy in the community are implemented as control measures, variations in temperature and rainfall that can affect the life cycle of parasite are among the factors of malaria prevalence over the years. The aim of this trend analysis was to assess the prevalence and the impact of malaria over the seasons and years. METHODS: A cross-sectional study using retrospective information was conducted at two health centers Gorgora and Chuahit in Dembia district. The data was collected from lab logbooks routinely diagnosed and registered for seven years. A systematic sampling technique was used by taking patient results from lab logbooks during the first ten days of every month. Data were entered directly into the EpiData Entry software version 3.1 and analysed with the SPSS software version 20. Moreover, a chi-square test with a level of significance set at less than 5% was used. RESULTS: From a total of 11,879 clients that participated, 56.6% were males. The overall malaria prevalence in the last seven years was 21.8%, and the dominant parasite was P. falciparum which accounted for 15.6% of the participants which was threefold higher than P. vivax in the seven-year trend. Moreover, at Gorgora health center, the prevalence which was 15% at the beginning of the study (2012) rose to 33.9% and 30.5% in 2017 and 2018, respectively. In the analysis of the seven years, October and September in which the prevalence of malaria was 32.6% and 27.2%, respectively, constituted the peak months. High malaria prevalence was observed in autumn (September to November) season, and the least was observed in spring (March to May) with the prevalence of (17.8%) (p ≤ 0.001). Malaria attack showed significant variability among different age groups, and the age group 15-29 and males were the most affected (p ≤ 0.001). CONCLUSION: In this study, malaria transmission remained high, which affected males more than females. Thus, appropriate season-based bed net use, health education, immediate patient treatment, and stagnant water drainage methods are needed to alleviate the problem.

Malaria Parasitemia in Febrile Patients Mono- and Coinfected with Soil-Transmitted Helminthiasis Attending Sanja Hospital, Northwest Ethiopia.

BACKGROUND: Malaria is a life-threatening disease associated with high morbidity and mortality. Helminths are among the most widespread infectious agents prevalent in tropical and subtropical regions of the developing world. Malaria and soil-transmitted helminthiasis (STHs) are coendemic and major public health problems in Ethiopia. The effects of helminth coinfection on malaria parasitemia remained poorly understood. Therefore, the objective of this study was to assess malaria parasitemia among malaria-monoinfected and malaria-soil-transmitted helminthiasis-coinfected febrile patients attending Sanja Hospital, Northwest Ethiopia. METHODS: A cross-sectional study with parallel groups was conducted to assess malaria parasitemia among malaria-monoinfected and malaria-soil-transmitted helminthiasis-coinfected febrile patients in Sanja Hospital from January to March 2019. Double population proportion formula was used for sample size calculation, and convenient sampling technique was used to select 134 study participants. Data were entered and analyzed by using the Statistical Package for Social Sciences (SPSS) version 20. Descriptive statistics, independent t-test, and one-way analysis of variance (ANOVA) were performed. A P value of <0.05 was considered as statistically significant. RESULTS: From 134 malaria-positive study participants, 67 were malaria-monoinfected and 67 were malaria-STHs-coinfected patients. Out of 67 malaria STHs-coinfected patients, 54 (80.6%) were infected with hookworm followed by Ascaris lumbricoides 11 (16.4%) and Strongyloides stercoralis 2 (3%). The mean Plasmodium parasite density was significantly higher in malaria-STHs-coinfected patients than in patients infected with only Plasmodium parasite density was significantly higher in malaria-STHs-coinfected patients than in patients infected with only P value of <0.05 was considered as statistically significant. Plasmodium parasite density was significantly higher in malaria-STHs-coinfected patients than in patients infected with only F = 6.953, P value of <0.05 was considered as statistically significant. CONCLUSIONS: Infections with STHs, especially hookworm, were positively associated with Plasmodium parasite density. The current study finding also revealed that increased worm burden of hookworm as expressed by egg intensity had significantly increased Plasmodium parasite density.Plasmodium parasite density was significantly higher in malaria-STHs-coinfected patients than in patients infected with only Plasmodium parasite density was significantly higher in malaria-STHs-coinfected patients than in patients infected with only.

The Prevalence of Metabolic Syndrome in Ethiopian Population: A Systematic Review and Meta-analysis.

Background: The metabolic syndrome is a clustering of hyperglycemia/insulin resistance, hypertension, dyslipidemia, and obesity which are risk factors for cardiovascular disease, type 2 diabetes and stroke, and all-cause mortality. The burden of metabolic syndrome is emerging alarmingly in low- and middle-income countries such as Ethiopia; however, there is lack of comprehensive estimation. This study aimed to determine the pooled prevalence of metabolic syndrome in Ethiopia. Methods: This systematic review and meta-analysis included original articles of observational studies published in the English language. Searches were carried out in PubMed, Google Scholar, and Africa Journals from conception to August 2020. A random-effects model was used to estimate the pooled prevalence of metabolic syndrome in Ethiopia. Heterogeneity was assessed using the I 2 statistic. Subgroup analysis was also conducted based on sex/gender and study subjects. Egger's test was used to assess publication bias. Results: Electronic and gray literature search retrieved 942 potentially relevant papers. After removing duplicates and screening with eligibility criteria, twenty-eight cross-sectional studies were included in this meta-analysis. The pooled prevalence of metabolic syndrome in Ethiopia was found to be 34.89% (95% CI: 26.77, 43.01) and 27.92% (95% CI: 21.32, 34.51) by using NCEP/ATP III and IDF criteria, respectively. The weighted pooled prevalence of metabolic syndrome was higher in females 36.74% (95% CI: 20.72, 52.75) and 34.09% (95% CI: 26.68, 41.50) compared to males 22.22% (95% CI: 14.89, 29.56) and 24.82% (95% CI: 18.34, 31.31) by using IDF and NCEP/ATP III criteria, respectively. Subgroup analysis based on the study subjects using NCEP/ATP III showed that the weighted pooled prevalence was 63.78%(95% CI: 56.17, 71.40), 44.55% (95% CI: 30.71, 52.38), 23.09% (95% CI: 19.74, 26.45), 20.83% (95% CI: 18.64, 23.01), and 18.45% (95% CI: 13.89, 23.01) among type 2 diabetes patients, hypertensive patients, psychiatric patients, HIV patients on HAART, and working adults, respectively. The most frequent metabolic syndrome components were low HDL-C 51.0% (95% CI: 42.4, 59.7) and hypertriglyceridemia 39.7% (95% CI: 32.8, 46.6). Conclusions: The findings revealed an emerging high prevalence of metabolic syndrome in Ethiopia. Therefore, early intervention is required for the primary prevention of the occurrence of metabolic syndrome and the further reduction of the morbidity and mortality related to it.

Sero-prevalence of Toxoplasma gondii and associated risk factors among psychiatric outpatients attending University of Gondar Hospital, Northwest Ethiopia.

BACKGROUND: Toxoplasmosis is caused by an obligatory intracellular coccidian protozoan organism, Toxoplasma gondii. It has a worldwide distribution, affecting one-third of the world population. Psychiatric patients have a higher risk of exposure to Toxoplasma gondii infection due to lack of good personal hygiene. The burden of toxoplasmosis among psychiatric patients in Ethiopia has not been studied extensively. Thus, the study aimed to determine the seroprevalence of Toxoplasma gondii and associated risk factors among psychiatric outpatients at the University of Gondar Comprehensive and Specialized Hospital Psychiatric clinic. METHODS: A cross-sectional study was conducted at the University of Gondar Comprehensive and Specialized Hospital from February to May 2018. Venous blood was collected from 304 study participants (152 psychiatric outpatients and 152 control groups). Anti-toxoplasma antibodies were determined using Onsite Toxo immunoglobulin G (IgG) and immunoglobulin M (IgM) Rapid Test. A Chi-square test was carried out to compare the two groups and a logistic regression analysis was conducted to check the association between variables. P-value less than 0.05 was taken as statistically significant. RESULTS: The seroprevalence rate of anti-Toxoplasma gondii IgG antibodies was 33.6, and 16.4% in the psychiatric outpatients and the control samples, respectively. Anti-Toxoplasma gondii IgM sero-prevalence was 1.3% in the former patients and 3.9% in the latter group. Owing cat (AOR = 2.862 95% CI = 1.445-5.666 P = 0.003), cleaning cat excreta (AOR = 2.966 95% CI = 1.317-2.652 P = 0.007), and farming (AOR = 2.058 95% CI = 1.018-4.163 P = 0.045) were found to be significantly associated with the sero-prevalence of anti-Toxoplasma gondii IgG antibody. CONCLUSIONS: This study highlighted that, the prevalence of anti-Toxoplasma gondii IgG antibodies was significantly higher in psychiatric outpatients than the control group (p = 0.001). Cat ownership, cleaning of cat excreta, and farming were found to be statistically significantly associated with the seroprevalence of anti-Toxoplasma gondii IgG antibody.

Prevalence and Reinfection Rates of Schistosoma mansoni and Praziquantel Efficacy against the Parasite among Primary School Children in Sanja Town, Northwest Ethiopia.

BACKGROUND: Schistosomiasis is among the most widespread chronic infections in the world. The magnitude of the infection may show variations across different areas with respect to time. Praziquantel is a first line drug of choice for the treatment of schistosomiasis although its low cure rate has been reported in different parts of the world. Thus, an assessment of the magnitude of the diseases, the efficacy of currently available drugs, and reinfection rates is crucial. OBJECTIVE: Our principal objective is to determine the prevalence and reinfection rates of Schistosoma mansoni and to evaluate the efficacy of PZQ against Schistosoma mansoni. METHOD: A school-based cross-sectional study was conducted on Sanja Elementary Schools, Sanja town, northwest Ethiopia. Stool specimens were examined using Kato-Katz method. Schoolchildren who tested positive for intestinal schistosomiasis and fulfilled the inclusion criteria took part in the efficacy and reinfection study. Positive participants were treated with 40 mg/kg of Praziquantel. Cure and egg reduction rates were evaluated three weeks after treatment. The intensity of infection was determined following the WHO's guideline. Moreover, the reinfection rate of those who were cured was evaluated after a six-month posttreatment period. Data were analyzed using SPSS version 20. RESULTS: At baseline, 130 (35%) of the 372 schoolchildren were found infected with Schistosoma mansoni. Out of the 130 infected schoolchildren, 112 (86.2%) had moderate infection intensity. Among the S. mansoni positive schoolchildren, 80 were included as study participants for the evaluation of PZQ efficacy, based on the inclusion criteria established by WHO. The cure and egg reduction rates were found to be 90% (72/80) and 99.5%, respectively. Of the seventy-two schoolchildren considered for the determination of reinfection rate, after 6 months of posttreatment, 13.9% were found to be reinfected. CONCLUSION: The schoolchildren in the three primary schools of Sanja are at moderate risk of the infection caused by S. mansoni. Although the therapeutic potency of PZQ at 40 mg/kg was efficient against S. mansoni, a high rate of reinfection was reported in the study site, suggesting the need for integrated schistosomiasis control measures.

The Prevalence of Malaria among Pregnant Women in Ethiopia: A Systematic Review and Meta-Analysis.

BACKGROUND: Malaria during pregnancy remains a major public health concern in tropical and subtropical countries. Moreover, malaria is increasingly associated with unwanted pregnancy outcomes such as an increased risk of abortion, stillbirth, premature delivery, and low-birthweight infants. Since pregnant women are most vulnerable to malaria, implementation of the appropriate prevention and control measures among this group is very important. Therefore, the current review was designed to assess the prevalence of both symptomatic and asymptomatic malaria among pregnant women in Ethiopia. METHOD: In this systematic review and meta-analysis we have followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. The databases used were PubMed, Google Scholar, HINARI, and Science Direct literature. Search terms used were "prevalence", "malaria", "pregnant women", and "Ethiopia". Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI) was used for critical appraisal of studies. The meta-analysis was conducted using STATA 14 software. The pooled meta-logistic regression was computed to present the pooled prevalence with a 95% confidence interval (CI). RESULT: Among a total of 10207 studies, seven studies were included in this analysis. The estimated pooled prevalence of malaria among pregnant women in Ethiopia was 12.72% (95% CI: 7.45, 17.98). In subgroup analysis, the prevalence of malaria showed a significant variation between asymptomatic and symptomatic cases, which was 7.83% (95% CI: 2.23, 13.43) and 17.97% (95% CI: 7.31, 28.92), respectively. CONCLUSION: The current systematic review and meta-analysis showed that the pooled prevalence of malaria among pregnant women was found to be relatively higher compared with the general population. Therefore, the existing prevention and control measures should be strengthen.

Prevalence of Intestinal Parasites and Associated Factors among Pulmonary Tuberculosis Suspected Patients Attending University of Gondar Hospital, Gondar, Northwest Ethiopia.

INTRODUCTION: Intestinal parasitic infections are among the major public health problems in developing countries. Hence, it is significant to explore coinfection with intestinal parasites and pulmonary tuberculosis because coinfection increases the complexity of control and prevention of pulmonary tuberculosis and parasitic diseases. OBJECTIVE: To assess the prevalence of intestinal parasites among pulmonary tuberculosis suspected patients. METHOD: Institutional based cross-sectional study was conducted at University of Gondar Hospital from March to May, 2017. Stool samples were taken from each participant and examined by direct microscopy and concentration technique. Descriptive statistics was performed and chi-square test was used to show the association between variables. P values of <0.05 were considered statistically significant. RESULTS: Intestinal parasites were detected in 50 (19.6%) among a total of 256 pulmonary tuberculosis suspected patients who were included in the study, whereas the prevalence of pulmonary tuberculosis was 16.8% (43/256). Pulmonary tuberculosis and intestinal parasite coinfection was detected in 5 (2.0%) of the participants. The most prevalent intestinal parasites infection in this study was Ascaris lumbricoides, 15 (5.85%), followed by Entamoeba histolytica/dispar, 14 (5.46%), and Hookworm, 13 (5.1%). CONCLUSION: The prevalence of intestinal parasites and their coinfection rate with pulmonary tuberculosis among pulmonary tuberculosis suspected patients were considerable.

Magnitude of Helicobacter pylori among Dyspeptic Patients Attending at University of Gondar Hospital, Gondar, Northwest Ethiopia.

BACKGROUND: Helicobacter pylori (H.pylori) infection is predominantly acquired in childhood from family members. The infection can cause dypepepsia, chronic and acute gastritis and gastric cancer. Dyspepsia is the most common illness in the Ethiopian population visiting outpatient department of health facilities, and it has also been associated with H.pylori infection. The aim of this study was to assess the magnitude of H.pylori and its associated factors among dyspeptic patients who visited University of Gondar Hospital Outpatient Department. MATERIALS AND METHODS: An institutional-based cross-sectional study was conducted on 354 dyspeptic patients. A systematic random sampling technique was employed to select study participants. Data were collected by using structured questionnaire via face-to-face interview. H.pylori infection was diagnosed using stool antigen test method. The data were entered into Epi info version 3.5.3 and transferred to Statistical Package for Social Sciences version 20. Both Bivariable and multivariable binary logistic regression analyses were performed to see the effect of independent variables on the dependent variable. RESULT: Of the total study participants, 201(56.8%), 195(55.1%) and 182(51.4%) were married, urban residents and females, respectively. The overall magnitude of H.pylori infection was 37.6%. In bivariable logistic regression analysis, sex and marital status were significantly associated with H.pylori infection, but in multivariable logistic regression analysis only marital status was significantly associated with H.pylori infection. CONCLUSION: The magnitude of H.pylori infection is high indicating that it is a public health problem in the study to area. According to this study, none of the variables were significantly associated with H.pylori infection. Hence, effective preventive, control and screening strategies need to be designed to reduce the burden of the disease.

Schistosoma mansoni and soil-transmitted helminths among preschool-aged children in Chuahit, Dembia district, Northwest Ethiopia: prevalence, intensity of infection and associated risk factors.

BACKGROUND: Intestinal schistosomiasis and soil-transmitted helminthiasis are the major public health problems globally. Compared with any other age group, pre-school aged children and school-aged children are the most exposed. There are few studies showing the burden of intestinal schistosomiasis, and soil-transmitted helminthiasis among pre-school aged children in Ethiopia. Hence, this study aimed to assess the prevalence of schistosoma mansoni and soil-transmitted helminths and associated risk factors among preschool aged children of Chuahit and surrounding Kebeles, Northwest Ethiopia. METHODS: A community based cross sectional study was conducted from February 2 to March 27 2015. Four hundred one preschool-aged children were included in the study by using two stage cluster sampling technique. Pretested structured questionnaire was employed to collected data via face-to-face interview technique. A single stool specimen was collected, and a portion of the sample was processed by Kato Katz method. RESULTS: Of the total children, 141 (35.2 %) harbored one or more intestinal helminthes. Schistosoma mansoni was found in 45 (11.2 %) of preschool age children. Ascaris lumbricoides was the predominant isolate, 77 (19.2 %) followed by S. mansoni, 45 (11.2 %). The least parasites isolated were Tania species, 2 (0.5 %). After adjusting for other variables, being mothers who did not have the habit of washing hands after toilet (AOR = 7.3, 95%CI: 2.97-17.95), being occupationally housewife mothers (AOR = 8.9, 95%CI: 2.27-25.4), using protected spring water as a main family source of water (AOR = 3.9, 95%CI: 1.2-12.3) and child habit of not wearing shoe (AOR = 1.91, 95%CI: 1.01-3.64) were significantly associated with high prevalence of soil-transmitted helminthiasis among preschool-age children in Chuahit. CONCLUSION: The current study showed that relatively higher level of STH and S. mansoni among preschool-aged children in Chuahit. This finding calls for a need of public health education, promotion of women education and provision of safe water to reduce the burden of soil-transmitted intestinal helminthiasis and schistosomiaisis.
