Survival and associated factors of mortality of preterm neonates admitted to Felege Hiwot specialized hospital, Bahir Dar, Ethiopia.

BACKGROUND: The complication of prematurity is the second commonest cause of under-five mortality in Ethiopia. Amhara region has the highest neonatal mortality rate in the country. There was no previous study and this study aimed to assess the survival of preterm neonates and its associated factors of preterm neonatal mortality admitted to Felege Hiwot Specialized Hospital, Bahir Dar, Ethiopia, to take necessary action to maximize survival of preterm babies in developing countries. METHODS: A retrospective cross-sectional study was conducted among 686 preterm neonates admitted in Felege Hiwot Specialized Hospital from 1 August 2017 to 30 July 2018. Kaplan-Meier survival curve was used to show the survival rate of preterm neonates and the multivariate Cox proportional hazards model was used to identify covariates of survival of preterm neonates. Those variables having a p-value less than 0.05 were statistically significant for the survival of preterm neonates. RESULT: Out of 686 preterm neonates admitted from 1 August 2017 to 30 July 2018, 49.1% neonates were improved and discharged and 36.1% died. The survival rate was 0%, 19.4%, 46.7% and 75% for gestational age <28 weeks, 28-31 + 6 weeks, 32-33 + 6 weeks and 34-36 + 6 weeks, respectively. In the multivariate Cox regression model, respiratory distress syndrome, necrotizing enterocolitis, asphyxia, hospital-acquired infection, birth weight, gestational age and place of delivery were significantly associated with time to death of preterm neonates at 95% confidence level (p < 0.05). CONCLUSION: The mortality rate (36.1%) of preterm neonates is unacceptably high in Felege Hiwot hospital compared to other similar hospitals in Ethiopia. More than 50% of preterm neonatal deaths can be prevented with available resources. Neonatal units with adequate and committed manpower, using a strict aseptic technique, proper follow-up, early detection and timely management of complications, are recommended to improve the survival of preterm neonates.

Bacterial isolates and their antimicrobial susceptibility patterns among pediatric patients with urinary tract infections.

OBJECTIVE: Urinary tract infection is a common pediatric problem with the potential to produce long-term morbidity. Therefore, appropriate diagnosis and prompt treatment is required. However, studies about magnitude of uropathogenicity and antimicrobial resistance pattern of pediatric urinary tract infection (UTI) are lacking in resource limited countries including Ethiopia. This study was aimed to determine bacterial isolates, antimicrobial susceptibility pattern among pediatric patients with UTI. MATERIAL AND METHODS: A cross- sectional study was conducted. Pathogenic bacterial isolates were identified by culture and biochemical methods following standard procedures. Antimicrobial susceptibility testing of the isolates for commonly used antibiotics was done using the standard disc diffusion method on Muller Hinton agar. Associations between dependent and independent variables were measured using chi-square test and within 95% confidence interval. P values <0.05 were considered as statistically significant. RESULTS: A total of 310 pediatric patients were included in the study, and 82 (26.45%) bacterial isolates were detected. Gram- negative bacteria were predominant etiologic agents of UTI in this study. E. coli was the most frequently occurring pathogen (n=45; 54.88%) followed by S. aureus and P.aeruginosa (n=8; 9.75% for both), P. vulgaris, P.aeruginosa (n=4; 4.88%, for both) and Enterococcus species (n=3; 3.66%). All K. pneumoniae, P. mirabilis, and K. ozanae straines were 100% resistance to ampicillin, followed by P. aeruginosa (87.5%) and E. coli (69%). While all Gram- positive bacterial isolates were 100% sensitive to ciprofloxacin. Malnutrition, history of catherization and previous history of UTI were independently associated with UTI (p=0.000). CONCLUSION: There was a high prevalence of uropathogenic bacteria and drug resistance particularly to ampicillin (72%) and tetracycline (37.80%). This condition indicates that antibiotic selection should be based on knowledge of the local prevalence of bacterial organisms and antibiotic sensitivities rather than empirical treatment.

Magnitude of cytopenias among HIV-infected children in Bahir Dar, northwest Ethiopia: a comparison of HAART-naïve and HAART-experienced children.

BACKGROUND: AIDS, caused by HIV, is a multisystem disease that affects hematopoiesis. The aim of this study was to assess cytopenias among HIV-infected children who had a follow-up at Felege Hiwot Referral Hospital, Bahir Dar, northwest Ethiopia. METHODS: An institution-based cross-sectional study was conducted between April and May 2013. Systematic random sampling method was used to select the study participants. Descriptive statistics, independent t-test as well as chi-square and logistic regression were used for analysis. A p-value <0.05 was considered as statistically significant. RESULTS: A total of 224 children (112 highly active antiretroviral therapy [HAART]-naïve and 112 HAART-experienced) participated in the study. The magnitude of anemia, thrombocytopenia, neutropenia, leukopenia and pancytopenia among HAART-naïve HIV-infected children were 30.4%, 9.8%, 8%, 4.5% and 1.8%, respectively. The overall prevalence of anemia, neutropenia, thrombocytopenia, leukopenia and pancytopenia were 29.5%, 8.9%, 8%, 4.5% and 1.4%, respectively. Cluster of differentiation-4 percentage and mean corpuscular volume were significantly different between HAART-experienced and HAART-naïve children. Being of younger age and severely immunosuppressed were risk factors of anemia. CONCLUSION: Anemia was the most common cytopenia, followed by neutropenia. Severe immunosuppression and younger age were significantly associated with anemia. Therefore, emphasis should be given for investigation and management of cytopenias in HIV-infected children, particularly for those who are immunosuppressed and of younger age.

The detection and antimicrobial susceptibility profile of Shigella isolates from meat and swab samples at butchers' shops in Gondar town, Northwest Ethiopia.

Food borne pathogens are major causes of deaths, illnesses and billions of dollars of expenses. The burden of food borne illness is worsened by the ever increasing rate of antimicrobial resistance microbes. Shigella, a bacterial pathogen associated with food, is reported to account for higher prevalence rates of food borne illness in different settings. A cross-sectional study was conducted from February 10 to June 30, 2013, at the butcher houses of Gondar town in the Northwest of Ethiopia to assess the prevalence and antimicrobial susceptibility pattern of Shigella. Cattle raw meat and swab samples from selected critical control points, including knives, chopping boards, and the hands and noses of butchers, were collected and analyzed. The identification of Shigella was carried out using colony characteristics, the Gram reaction, and biochemical tests. Antimicrobial susceptibility testing was performed using the Kirby-Bauer disc diffusion method. The overall hygienic status of the butcher shops was also assessed using a checklist. An observational analysis revealed that the sanitary condition of the butcher shops and their premises was poor. Of 306 samples screened, 10.5% were positive for Shigella. Approximately 7.4% of meat samples and 10.2% of swab samples were contaminated with Shigella. Out of the total Shigella isolates, 90.6%, 46.9%, 18.8% and 9.4% were resistant to ampicillin, amoxicillin, ceftriaxone and tetracycline, respectively. A multidrug resistance pattern was recorded in 27.8% of the isolates. In conclusion, the safety of meat sold at Gondar butchers houses was poor. The identified Shigella isolates showed high levels of drug resistance and multidrug resistance patterns for commonly used antimicrobials in veterinary and human medicine. Practicing wise use of antimicrobials and strict sanitary interventions at different critical control points is strongly recommended, in addition to further in-depth studies to prevent unprecedented consequences from shigellosis.

Prevalence and associated risk factors of anemia among HIV infected children attending Gondar university hospital, Northwest Ethiopia: a cross sectional study.

BACKGROUND: Anemia is the most common hematological abnormalities in HIV patients and it is a wide spread public health problem. The World Health Organization estimates that over 2 billion people are anemic worldwide with more than 100 million of these anemic children living in Africa. In Ethiopia, there is limited information about the prevalence and factors associated with anemia among HIV positive children. Thus, this study aimed to determine the prevalence and associated factors of anemia among HIV infected children aged 6 months to 14 years in Gondar university Hospital antiretroviral treatment clinic. METHODS: A cross-sectional study was conducted on 265 HIV infected children from February to June 2013 on HIV infected children attending Gondar university Hospital ART clinic. The study subjects were selected with systematic random sampling technique. Data of socio demographic characteristics and clinical conditions of the study subjects was collected using a structured pretested questionnaire. Hemoglobin value and CD4 counts were determined by cell Dyne 1800 and FACS count machine respectively. WHO Cut off value of hemoglobin was taken and adjusted to altitude to define anemia. Data was analyzed by using the SPSS version 20 statistical software and bivariate and multivariate logistic regression was used to identify predictors. RESULTS: Anemia was present in 16.2 % (43 /265) of children, 60.5 % of them had mild anemia, 37.2 % had moderate anemia and 2.3 % had severe anemia. About 46.5 % of anemic children had normocytic-normochromic anemia followed by macrocytic-normochromic anemia (39.5 %). In this study, anemia was associated with eating green leafy vegetables (OR = 0.43, 95 % CI (0.188-0.981) and being on cotrimoxazole treatment (OR = 2.169, 95 % CI (1.047-4.49). But there was no significant association with age, sex, WHO clinical stage, opportunistic infections, intestinal parasitic infection and CD4 count percentage. CONCLUSIONS: The majority of HIV positive children in Northwest Ethiopia have a mild type of anemia and the increase in prevalence of anemia is due to being on cotrimoxazole and eating green leafy vegetables. Therefore, early diagnosis and treatment of anemia is essential in these patients.

Bacterial isolates and their antimicrobial susceptibility pattern among patients with external ocular infections at Borumeda hospital, Northeast Ethiopia.

BACKGROUND: Bacteria are major cause of ocular infections and possible loss of vision. The emergence of antimicrobial resistant bacteria increases the risk of treatment failure with potentially serious consequences. The aim of this study was to determine the prevalence of bacterial isolates and their antimicrobial susceptibility pattern among patients with external ocular infections. METHODS: A cross sectional study was conducted among 160 patients with external ocular infections at Borumeda hospital, Northeast Ethiopia. Socio-demographic and clinical data were collected using structured questionnaire. External ocular specimens were collected using sterile swabs and inoculated on MacConkey agar, Chocolate agar and Blood agar culture Medias. Presumptive isolates were further identified by a series of biochemical tests. The antimicrobial susceptibility patterns of the isolates were determined by disk diffusion method. RESULT: The overall prevalence of bacterial pathogens among external ocular samples was 59.4 %. The majority of the isolates (93.7 %; 89/95) were Gram positive and the other 6.3 % (6/95) Gram negative bacteria. The proportion of coagulase negative Staphylococci among the Gram positive bacterial isolates was 53.7 % (n = 51/95). All Gram positive isolates were susceptible for vancomycin but 67.4 % (n = 60/95) of them were resistant against amoxicillin. Moreover, drug resistance to tetracycline, norfloxacylin, ceftriaxone and ciprofloxacin were observed among Gram negative bacteria isolates. CONCLUSION: The prevalence of bacterial pathogens among external ocular samples was high and the predominant isolate was coagulase negative Staphylococci. Exceptionally high amoxicillin resistance was observed among Gram positive bacterial isolates that may dictate to conduct drug susceptibility test routinely.

Prevalence and antimicrobial susceptibility patterns of Salmonella isolates in association with hygienic status from butcher shops in Gondar town, Ethiopia.

BACKGROUND: Salmonella has been recognized as a major cause of food borne illness associated with meat products worldwide. The wide spread of antimicrobial-resistant Salmonella has been a serious global human and animal health problem. The aims of this study were to estimate the prevalence and antimicrobial susceptibility pattern of Salmonella isolates from butcher shops of Gondar town, Ethiopia. METHODS: A cross-sectional study was conducted from February to June, 2013 in Gondar town. After receiving written consent from the study participants, raw meat and swab samples from butcher shops' utensils and meat handlers were collected and tested using standard bacteriological methods. The isolates were identified using colony characteristics, Gram-reaction, biochemical reaction and sugar tests. Antimicrobial susceptibility test was performed using Kirby-Bauer disc diffusion method. Check list was used to record general hygienic conditions and practices in the butcher shops. The data was entered and analyzed using SPSS version 20.0. RESULTS: Butcher shop premises and utensils sanitation and personnel's hygiene were poor. The overall prevalence of Salmonella was 17.3 %. Salmonella was detected in 32 (35.6 %) meat samples, 13 (23.2 %) hand swabs, 5 (9.1 %) knife swabs, and 3 (5.6 %) chopping board surface swabs. Of the total 53 Salmonella isolates subjected to antimicrobial susceptibility test, 47 (88.7 %), 35 (62.3 %), 19 (35.8 %), 17 (32.1 %) and 16 (30.2 %) of them exhibited resistance to Ampicillin, Amoxicillin, Nitrofuranthoin, Tetracycline, and Sulfamethoxazole-Trimethoprime, respectively. Furthermore; 15 (28.3 %) of the isolates were multidrug-resistant from which highest isolation was recorded from meat samples and 40 (75.5 %) isolates of Salmonella showed resistance to two or more antimicrobial agents tested. Interestingly, all of the isolates were susceptible to Gentamycin and Ceftriaxone. CONCLUSION: The general sanitary condition of the butcher shops and utensils used and personnel hygiene were not to the recommended standards. Contamination of meat, knives, and meat handlers hand with Salmonella was found high. Furthermore; multidrug-resistant Salmonella is circulating in the butchers' shop which is strong enough to warrant the revision of butcher shops sanitation policy and treatment regimen for infections implicated by Salmonella in the study area. Further in-depth study including serotyping and antimicrobial resistant gene identification is recommended.

Magnitude of HIV and syphilis seroprevalence among pregnant women in Gondar, Northwest Ethiopia: a cross-sectional study.

BACKGROUND: Human immunodeficiency virus (HIV) and syphilis are major public health problems in sub-Saharan Africa, causing numerous adverse pregnancy outcomes. The aim of study was to assess the magnitude of HIV and syphilis seroprevalence among pregnant women at University of Gondar Teaching Hospital. METHOD: The study was conducted between March and May, 2012. Sociodemographic data were collected through face-to-face interview. HIV1/2 was tested following current national HIV1/2 testing algorithm. Syphilis infection was also tested using the rapid plasm reagin test for screening and Treponema pallidum hemagglutination as a confirmatory test. Both bivariate and multivariate analysis were used to identify factors associated with HIV and syphilis seroprevalence from selected sociodemographic variables. RESULTS: Of 300 women, 31 (10.33%), eleven (3.7%), and three (1%) were seroreactive for HIV, syphilis, and HIV-syphilis coinfection, respectively. High seroprevalence of HIV was found in women ages 25-30 years (13.4%), and women whose husbands attended primary school (19.7%). Syphilis was high in women occupationally housewives (15.2%) and whose husbands were illiterate (11.5%). HIV was associated with husband illiteracy (AOR [adjusted odds ratio] of 4.13, 95% CI [confidence interval] [1.01, 16.95]) and primary educational level of husbands (AOR [95% CI] =3.83 [1.50, 9.90]), whereas syphilis was associated with illiteracy of husband (AOR [95% CI] =7.25 [1.74, 30.30]). CONCLUSION: Seroprevalence of HIV and syphilis was high. Low husband educational status was a risk factor for HIV and syphilis. Therefore, substantial efforts have to be made to reinforce prevention strategies and to screen as early as possible to prevent mother-to-child and further horizontal transmission.

Prevalence of smear positive pulmonary tuberculosis in Gondar prisoners, North West Ethiopia.

OBJECTIVE: To assess the prevalence and risk factors of smear positive pulmonary tuberculosis among Gondar town prisoners, North West Ethiopia. METHODS: A cross sectional study was conducted from February to July, 2008 in Gondar Prison. Prisoners with cough duration of more than two weeks were involved in the study by giving three sputum samples and filling the questionnaires prepared for risk factor assessment. Acid fast staining technique was employed to detect the presence of the Mycobacterium tuberculosis bacilli in the sputum samples. Data was analyzed using SPSS version13 computer software and presented in table. Chi-square test was used to assess associations and a P-value less than 0.05 was taken as significant. RESULTS: A total of 384 prisoners, 349 male and 35 females, with a mean age of 33.3 years were involved in the study. The prevalence of smear positive pulmonary tuberculosis among those prisoners with cough duration of more than two weeks was 8.59%. Only the length of imprisonment had a significant association (χ (2)= 18.82, P-value<0.0001) with the prevalence of tuberculosis. CONCLUSIONS: This study indicated that tuberculosis among prisoners with cough duration of more than two weeks in Gondar prison is very high. Therefore Periodic screening of the prisoners and screening of newly introduced prisoners should be practiced so as to minimize the burden of tuberculosis in prisoners.

Metabolic syndrome among hypertensive patients at University of Gondar Hospital, North West Ethiopia: a cross sectional study.

BACKGROUND: Data is sparse concerning the magnitude of metabolic syndrome (MetS) in developing countries like Ethiopia whose major health problem had long been under-nutrition and infectious diseases rather than non-communicable diseases (NCDs) including hypertension, obesity and MetS. However, it is obvious that the NCDs are recently taking over and becoming the major health care concerns in the developing countries. This pattern could be partly explained by the nation's sustained economical growth in the last few decades in addition to the increasing globalization related adoption of western lifestyle. The aim of this study was to assess the prevalence of metabolic syndrome and associated factors among hypertensive patients in North West Ethiopia. METHOD: A cross sectional study was conducted on 300 hypertensive individuals who get follow-up care at University of Gondar Hospital after diagnosed as hypertensive. The WHO STEP-wise approach to surveillance of NCD was used. Fasting blood glucose level, triglyceride and high density lipoprotein cholesterol were determined using standardized laboratory procedures. RESULT: The prevalence of metabolic syndrome was 40.7% and 39.3% according to the modified NCEP-ATP III and IDF criteria respectively. Low HDL-c was found to be the most frequently encountered (81.3%) component of MetS other than the hypertension. Being female was significantly associated with MetS (AOR = 4.34; 95% CI: 2.09, 8.99) using IDF and (AOR = 3.30; 95% CI: 1.66, 6.58) using NCEP-ATP III criteria. Abnormal BMI which included both high and low BMI was found to have significant association with MetS (AOR = 3.10; 95% CI: 1.73, 5.58) using IDF and (AOR = 1.84; 95% CI: 1.05, 3.22) as diagnosed using the NCEP-ATP III criteria. CONCLUSION: We recommend a comprehensive medical care approach to hypertensive patients to adequately assess and address the additional components of MetS which are known to potentiate the risks of cardiovascular diseases among hypertensive patients.

Helicobacter pylori infection and its association with anemia among adult dyspeptic patients attending Butajira Hospital, Ethiopia.

BACKGROUND: Helicobacter pylori infection is associated with anemia. Understanding the magnitude of H. pylori infection and its association with anemia is important in the management of anemic patients. The aim of this study was to assess the association between H. pylori infection and anemia among dyspeptic patients. METHODS: A cross-sectional study was conducted in Butajira Hospital, Southern Ethiopia among 401 systematically dyspeptic patients. A structured questionnaire was used to collected data about the patient characteristics. Blood samples were analyzed for red blood cell parameters. Stool samples were assessed for the presence of H. pylori antigens and the presence of intestinal helminthes. Data were summarized in frequencies (%) and mean (SD) as appropriate. Chi-square test, logistic regression and independent t-tests were used in the analysis as needed. In all cases P-value <0.05 was considered as statistically significant. RESULTS: The overall prevalence of H. pylori infection was 52.4% and it was significantly associated with age, presence of intestinal parasites, smoking habit, alcohol drinking habit and body mass index. The prevalence of anemia among H. pylori infected patients (30.9%) was significantly (P < 0.001) higher than uninfected patients (22.5%). The mean (SD) values of HGB, MCV, MCH, MCHC, HCT and RBC count was significantly different between H. pylori infected and uninfected patients. CONCLUSION: This study showed high prevalence of H. pylori infection among dyspeptic patients and this was associated with age and some behavioral characteristics of the patients. H. pylori infected patients showed high rate of anemia prevalence as compared to their H. pylori unifected counter parts. From this study it can be recommended that intervention activities related to the behavioral characteristics and prevention of intestinal parasitic infections should be in place. The cross sectional nature of the study has a limitation to show cause and effect associations and hence association between H. pylori infections with anemia need to be investigated in cohort type studies.

Determination of hematological and immunological parameters among HIV positive patients taking highly active antiretroviral treatment and treatment naïve in the antiretroviral therapy clinic of Gondar University Hospital, Gondar, Northwest Ethiopia: a comparative cross-sectional study.

BACKGROUND: Anemia, leucopenia and thrombocytopenia are the commonest hematological abnormalities resulting from human immunodeficiency virus infection. The use of antiretroviral drugs could positively or negatively affect these disorders. Thus a specific diagnosis and a determination of hematological and immunological parameters are required for initiating and monitoring early treatment to avert disease progression. Therefore, this study aimed to compare hematological and immunological parameters in HIV positive patients taking antiretroviral therapy and those treatment naïve patients in Gondar University Hospital. METHODS: A comparative cross-sectional study was conducted on a total of 290 HIV patients from February to May 2012 in Gondar University Hospital. Study subjects were divided in to two groups: 145 HIV positive treatment naïve and 145 on HAART. Data of socio demographic characteristics and clinical conditions of the study subjects was collected using structured pretested questionnaire at their follow up date. Hematological and immunological parameters were collected and processed by cell Dyne 1800 and BD FACS count respectively. The variables compared here were Hematological parameters (Total and differential WBC, RBC, Hgb, HCT, MCV, MCH, MCHC, RDW, PLT, and MPV) and CD4 count. In order to compare means independent sample T-test was conducted using SPSS version 20 statistical software. P- Value < 0.05 was considered as significant. RESULT: Prevalence of anemia, leucopenia, thrombocytopenia, neutropenia and lymphopenia were 11.7%, 35.9%, 4.1%, 28.3% and 2.1% in patients on HAART and 29.7%, 16.6%, 9%, 14.5% and 2.1% in HAART naïve patients respectively. There was a significant difference in total WBC, RBC, Hgb, MCV, MCH, MCHC, MPV and CD4 counts between patients on HAART and HAART naïve patients. CONCLUSION: Prevalence of anemia was high in HAART naïve patients while leucopenia and neutropenia prevalence was higher in patients on HAART and their prevalence increased as the CD4 count decreased. HIV Patients should be investigated for hematological and immunological changes following with appropriate therapeutic interventions.

Prevalence and Predictors of Maternal Anemia during Pregnancy in Gondar, Northwest Ethiopia: An Institutional Based Cross-Sectional Study.

Background. Anaemia is a global public health problem which has an eminence impact on pregnant mother. The aim of this study was to assess the prevalence and predictors of maternal anemia. Method. A cross-sectional study was conducted from March 1 to April 30, 2012, on 302 pregnant women who attended antenatal care at Gondar University Hospital. Interview-based questionnaire, clinical history, and laboratory tests were used to obtain data. Bivariate and multivariate logistic regression was used to identify predictors. Result. The prevalence of anemia was 16.6%. Majority were mild type (64%) and morphologically normocytic normochromic (76%) anemia. Anemia was high at third trimester (18.9%). Low family income (AOR [95% CI] = 3.1 [1.19, 8.33]), large family size (AOR [95% CI] = 4.14 [4.13, 10.52]), hookworm infection (AOR [95% CI] = 2.72 [1.04, 7.25]), and HIV infection (AOR [95% CI] = 5.75 [2.40, 13.69]) were independent predictors of anemia. Conclusion. The prevalence of anemia was high; mild type and normocytic normochromic anemia was dominant. Low income, large family size, hookworm infection, and HIV infection were associated with anemia. Hence, efforts should be made for early diagnosis and management of HIV and hookworm infection with special emphasis on those having low income and large family size.

Current status of soil transmitted helminths and Schistosoma mansoni infection among children in two primary schools in North Gondar, Northwest Ethiopia: a cross sectional study.

BACKGROUND: School age children are one of the groups at high risk for intestinal parasitic infections especially in developing countries like Ethiopia as the supply of good quality drinking water and latrine coverage are poor. Though there are previous data on the prevalence of soil transmitted helminths (STHs) and Schistosoma mansoni infection among these high risk groups current status in the study area is unknown. Therefore, the aim of this study was to determine the current prevalence and associated risk factors of STHs and S. mansoni infections among school children. METHODS: A cross-sectional study was carried out in Gorgora and Chuahit towns, North Gondar Zone, North West Ethiopia from January 20 to February 25, 2012 involving 261 school children. A pre-tested and structured questionnaire was used to collect socio-demographic data and possible risk factors. Stool samples were collected and examined for intestinal parasites using Kato Katz method. Chi-square test was used to see if there is association between sociodemographic factors and other risk factors for STH and S. mansoni infection and odds ratio with 95% CI was computed as measures of association. P < 0.05 was taken as statistically significant. RESULTS: Out of the 261 study participants, 174 (66.7%) were infected with one or more species of intestinal parasites. Ascaris lumbricoides was the predominant isolates (39.8%) followed by Trichuris trichiura (6.1%) and Hookworms (4.9%). Schistosoma mansoni was detected in 33.7% of the children. Among infected individuals, 9.5% were coinfected by S. mansoni and A. lumbricoides and 1.5% with S. mansoni and T. trichiura. Swimming habit (OR: 2.536, 95% CI: 1.122, 5.737, P = 0.022) was significantly associated with S. mansoni infection. CONCLUSION: The prevalence of STH and S. mansoni was high among school children. This should call for implementation of an integrated strategy to reduce morbidity and control of transmission of STH and S. mansoni.

Knowledge, attitude and practice towards voluntary counseling and testing among university students in North West Ethiopia: a cross sectional study.

BACKGROUND: Voluntary counseling and testing (VCT) is one among different approaches which have been implemented as an attempt to slow the spread of HIV infection and minimize its impact at the individual, family and society level. VCT is perceived to be an effective strategy in risk reduction among sexually active young people like tertiary level students. Ethiopia as a country with high burden of HIV started responding to the epidemic by preparing and updating guidelines on VCT. The objective of this study was to assess the level of knowledge, attitude and practice of Voluntary Counseling and Testing (VCT) for HIV among university students in North West Ethiopia. METHODS: A cross sectional study was conducted from February to May 2010 using a stratified sampling method to enroll students from different faculties into the study. A total of 330 university students filled in a self-administered questionnaire with response rate of 97.3%. Main outcome measures included level of knowledge, attitude and practice of VCT for HIV. A chi-square test was used to determine an association between a number of independent factors and dependant variables. RESULT: About 66.1% of the study participants were males with a mean age of 20 years. Majority (75.6%) of the respondents were Orthodox with 63% reported living in urban areas before joining the university. From the study participants 86.3% were knowledgeable on VCT, 73.3% had positive attitude towards VCT for HIV and 61.8% had had VCT for HIV in the past. Previous residence before joining the university, level of education, sex and religion were among the sociodemographic variables that showed statistically significant association with the one or more of the outcome variables. Fear of positive results, stigma and discrimination following the positive results were reported as main barriers for VCT uptake. CONCLUSION: The findings reveal important barriers for VCT uptake and suggest strategies to reduce stigma and discrimination.

Physicians' and nurses' satisfaction with the clinical laboratory service of Gondar University Hospital, northwest Ethiopia.

OBJECTIVES: To assess physicians' and nurses' satisfaction with the service provided by the laboratory at Gondar University Hospital. METHODS: We conducted a cross-sectional study involving 196 nurses and physicians. RESULTS: Overall level of satisfaction was 51.1% for nurses and 51.5% for physicians. Lack of consistency in the quality of laboratory work, absence of a timely report of critical values, test turnaround time, acceptability of results released, and reporting of reference ranges with test results were areas mentioned as sources of dissatisfaction. CONCLUSIONS: The study showed wide room for improvement. In addition to taking intervention, root causes of dissatisfaction need to be investigated and means of improving the satisfaction level should be designed and implemented.

Bacteriological safety of blood collected for transfusion at university of gondar hospital blood bank, northwest ethiopia.

Background. Transfusion associated bacterial infection has remained more frequent with a sever risk of morbidity and mortality. This study assessed the bacteriological safety of blood collected for transfusion. Method. A cross-sectional study was conducted at University of Gondar hospital blood bank from December 2011 to June 2012. Bacterial isolation, identification, and antimicrobial susceptibility tests were done as per the standard procedure. Chi-square test and P value were used to assess associations between risk factors and the bacterial isolation rate. Results. Twenty-one (15.33%) blood units were found contaminated with bacteria, and 95.24% contamination was due to external sources. The commonly isolated bacteria were Staphylococcus aureus, Coagulase negative Staphylococci, Escherichia coli, Klebsiella species, Streptococci species, Enterobacter species, and Citrobacter species. All of the bacteria isolated were 100% sensitive to Gentamicin, Chloramphenicol, Amoxicillin, and Doxycycline. Multiple antimicrobial resistances were observed in 66.7% of the isolates. Not using glove by phlebotomist, touching disinfected phlebotomy site and double puncture at the same hand or both hands of a donor were found to be risk factors for bacterial contamination. Conclusion. Bacterial contamination of blood to be transfused is a common problem in the hospital. So attention should be given to activities performed at the blood bank for safe transfusion practices.

Assessment of knowledge, attitude and practice towards post exposure prophylaxis for HIV among health care workers in Gondar, North West Ethiopia.

BACKGROUND: HIV/AIDS infection in health care facility has become a major health problem. Especially in resource poor setting health care workers are managing huge number of HIV infected patients that made them to be more exposed to HIV infection. This situation makes the use of post exposure prophylaxis for HIV very important. Therefore the aim of the study was to assess knowledge, attitude and practice of health care workers towards post exposure prophylaxis for HIV. METHODS: Cross-sectional study was conducted among 195 health care workers from February 15 to June 20, 2012. Data was collected using self-administered questionnaire and entered and analyzed using SPSS-20 version. Results were summarized in percentages and presented in tables. RESULTS: Significant proportions of respondents, 72 (36.9%), were found to have inadequate knowledge about post exposure prophylaxis for HIV. However the majority of respondent 147 (75.4%) had good attitude toward the PEP and significant number of the respondents, 66 (33.8%), had been exposed to blood, body fluids, needles or sharp objects once or more times while giving care for patients. Among these exposed, 49 (74.2%) took PEP but the rest 17 (25.7%) didn't take PEP. From these exposed respondents that took PEP, 23 (46.9%) correctly started taking of PEP at exact initiation time, but the rest started after the recommended initiation time. Among those who took PEP, 39 (79 .6%) completed taking the drug, however 10 (20.4%) didn't complete the PEP regimen. CONCLUSION: As a conclusion, significant proportion of study subjects had less knowledge and practice even though the majority of respondents had favorable attitude towards PEP. Therefore, a formal training for all HCWs regarding PEP for HIV and also establishing a 24 hour accessible formal PEP centre with proper guideline is recommended.

Effect of malaria on HIV/AIDS transmission and progression.

Malaria and HIV are among the two most important global health problems of developing countries. They cause more than 4 million deaths a year. These two infections interact bidirectionally and synergistically with each other. HIV infection increases the risk of an increase in the severity of malaria infection and burdens of malaria, which in turn facilitates the rate of malaria transmission. Malaria infection is also associated with strong CD4+ cell activation and up-regulation of proinflammatory cytokines and it provides an ideal microenvironment for the spread of the virus among the CD4+ cells and for rapid HIV-1 replication. Additionally, malaria increases blood viral burden by different mechanisms. Therefore, high concentrations of HIV-1 RNA in the blood are predictive of disease progression, and correlate with the risk of blood-borne, vertical, and sexual transmission of the virus. Therefore, this article aims to review information about HIV malaria interactions, the effect of malaria on HIV transmission and progression and the implications related to prevention and treatment of coinfection.

Prevalence of dyslipidemia among HIV-infected patients using first-line highly active antiretroviral therapy in Southern Ethiopia: a cross-sectional comparative group study.

BACKGROUND: Data on lipid profile abnormalities among patients receiving highly active antiretroviral treatment in Ethiopia are very limited. The aim of this study was to determine the prevalence of dyslipidemia and characteristics of lipid profiles among patients living with human immunodeficiency virus (HIV) using first-line highly active antiretroviral therapy (HAART) in Southern Ethiopia. METHODS: This cross sectional comparative group study was conducted between March and May 2012, and included 113 HIV infected patients treated for a minimum of one year with first-line HAART regimens that included Efavirenz and Nevirapine (HAART group) and others 113 who had never received HAART (pre-HAART group). Serum lipid profiles were determined after overnight fasting and dyslipidemia was assessed according to the United State National Cholesterol Education program-III guideline. For statistical analysis Chi-square, student's t-test, and logistic regression were used using Statistical Package for Social Sciences (SPSS) Version 20. RESULT: Ninety-three (82.3%) of HAART and 87 (76.9%) pre-HAART patients had at least one laboratory abnormality, which is compatible with a diagnosis of dyslipidemia. Total cholesterol ≥ 200 mg/dl occurred in 43.4% of HAART and 15.9% pre-HAART patients (p=<0.0001), whereas HDL-cholesterol below 40 mg/dl occurred in 43.4% and in 63.7% respectively, (p=0.002). The LDL-cholesterol ≥ 130 mg/dl occurred in 33.6% of HAART and 15% pre-HAART patients (p=0.001), while triglycerides ≥ 150 mg/dl occurred in 55.8% and 31.0% respectively, (p=0.001). Receiving of HAART was significantly and positively associated with raised total cholesterol, LDL-cholesterol, and triglycerides. The adjusted odds ratio (95% CI) of HAART-treated vs. pre-HAART was 3.80 (1.34-6.55) for total cholesterol ≥ 200 mg/dl; 2.64 (1.31-5.32) for LDL- cholesterol ≥ 130 mg/dl and 2.50 (1.41-4.42) for triglycerides ≥150 mg/dl. CONCLUSION: Use of first-line antiretroviral therapy regimens that contain Efavirenz and Nevirapine were associated with raised total cholesterol, LDL-cholesterol, and triglycerides, an established atherogenic lipid profiles. Lipid profiles should be performed at baseline before commencement of antiretroviral therapy and then periodically through treatment follow-up to monitor any rising trends.
