RESUMO

BACKGROUND: Noroviruses (NoVs) are the leading cause of diarrheal disease among all age groups worldwide, with an increased burden in developing countries. As there is no surveillance, epidemiological data is limited in Ethiopia. Hence, this study aimed to investigate the prevalence and associated factors of NoV infection among patients with diarrhea in the Amhara National Regional State, Ethiopia. METHODS: A prospective health facility-based cross-sectional study was conducted from May 2021 to November 2021. A total of 550 study participants of all age groups with symptoms of diarrhea were proportionately assigned to the four study areas, area with three health facilities. Study participants were systematically sampled in each health facility. A fecal sample from each case was collected. The RNA was extracted and tested for NoV by one-step RT-PCR. Sociodemographic and other variables were gathered using a pre-tested questionnaire. A descriptive analysis was performed. Both binary and multiple logistic regressions were utilized to identify factors associated with NoV infection. Variables with a p-value < 0.05 in the final model were considered statistically significant. RESULTS: Five hundred nineteen out of 550 samples were analyzed (94.4% response rate). The overall prevalence of NoV was 8.9% (46/519). The positivity rates were higher among the elderly (33.3%) and under-5 children (12.5%). Both genogroup I and genogroup II (GII) were identified, with GII being the predominant, at 82.6% (38/46). Of all participants, only 20% reported a history of vomiting. Norovirus infection was more prevalent among participants from Debre Tabor (AOR = 4, 95%CI: 1.2-14) and Bahir Dar areas (AOR = 3.6, 95%CI: 1.04-11) compared to Debre Markos. Additionally, older adults (AOR = 7, 95% CI: 2-24) and under-5 children (AOR = 3.5, 95% CI: 2.8-12) were disproportionately affected compared to adults. The previous history of diarrhea (AOR = 3.6, 95% CI: 1.7-7) was a significant factor contributing to NoV infections. Moreover, the odds of NoV infection were higher among individuals with a high frequency of diarrhea (AOR = 15.3, 95%CI: 7.6-43) and vomiting (AOR = 3.5, 95%CI: 1.5-8). CONCLUSIONS: The prevalence of NoV was considerably high, with the predominance of NoV-GII. The positivity rate was higher among the extreme age groups and varied across the study areas. To obtain a comprehensive understanding of the virus`s epidemiology and its genetic diversity, further research is warranted.

RESUMO

BACKGROUND: The initiation of highly active antiretroviral therapy (HAART) plays a significant role in the clinical management of HIV infected people by preventing morbidity and mortality. This benefit becomes, the most terrible when treatment failure develops. Thus, this research aims to assess the prevalence and associated factors of treatment failure among HIV/AIDS patients on HAART attending University of Gondar Referral Hospital Northwest Ethiopia. RESULTS: Patients on ART with a minimum of 6 months and up to 12 years of treatment were being enrolled. The prevalence of treatment failure, immunological failure and virological failure among people living with HIV/AIDS attending University of Gondar referral hospital were 20.3, 13.2, and 14.7%, respectively. Patients who had no formal education (Adjusted odds ratio (AOR): 3.8; 95% CI, 1.05-13.77), primary level education (AOR: 4.2; 95% CI, 1.16-15.01) and duration on ART < 6 years (AOR: 2.1; 95%CI, 1.12-3.81) were a significant risk factor. However, initial adult regimen D4T +  3TC+ EFV (AOR: 0.025; 95% CI, 0.002-0.36), AZT +3TC + NVP (AOR: 0.07; 95% CI, 0.01-0.71), AZT +  3TC + EFV (AOR: 0.046; 95% CI, 0.004-0.57) andTDF+3TC + EFV (AOR: 0.04; 95% CI, 0.004-0.46) were significantly protective for treatment failure. CONCLUSIONS: Timely and early identification of associated factors and monitoring antiretroviral therapy treatment failure should be done to enhance the benefit and to prevent further complication of the patients. It is preferable to initiate ART using any one of the following ART regimens: AZT +3TC + NVP, AZT + 3TC + EFV and TDF + 3TC + EFV to prevent treatment failure. Since the prevalence of this treatment failure and its associated factor may be different from other ART centers and community in Ethiopia, further national representative institutional based cross-sectional researches are needed across all ART centers of Ethiopia in order to determine the prevalence of treatment failure and its associated factors.

RESUMO

BACKGROUND: Despite availability of effective treatment and the implementation of focused antenatal care (ANC), still the prevalence of syphilis persists in Ethiopia. Yet, data is not found in southern Ethiopia. Therefore, this study was conducted to determine the seroprevalence and associated factors of syphilis among pregnant women in Yiregalem Hospital, Southern Ethiopia. METHODS: A cross-sectional study was conducted among pregnant women from October 2015 to August 2016. Data on socio-demography and obstetric conditions of pregnant women were collected using a structured questionnaire. Serum samples were screened for syphilis using rapid plasma regain (RPR) test and those found seropositive were further confirmed by Treponema pallidum haemagglutination assay (TPHA) test following the manufacturer's instruction. HIV results were reviewed from records. The data were analyzed using SPSS version 20 software. RESULTS: Of 494 pregnant women, 204(41.3%) were first ANC visit attenders. Of these, 123(60.3%) were after the 12th gestational week. Sero-prevalence of syphilis and HIV was found to be 5.1% (25/494; 95 CI, 3.2-7.1%) and 10.3% (51/494; 95 CI, 7.7-13.2%), respectively. The overall prevalence of syphilis and HIV co-infection was 2.2% (11/494). Women with HIV infection were significantly more likely to be syphilis-seropositive (AOR = 10.3, 95%CI, 4.213-25.185) than HIV negatives. CONCLUSIONS: High seroprevalence of syphilis particularly among HIV positive women and late first ANC visit attenders in the study area calls for further ramping up of current intervention measures. Like integration of syphilis testing and treatment to the already established HIV prevention program and creating awareness about early ANC visit and follow-up.

RESUMO

BACKGROUND: Dengue is one of the most common arboviral diseases with increased outbreaks annually in tropical and subtropical areas. In Ethiopia, there are no data regarding clinical, hematological and biochemical parameters which are very important in the clinical management of dengue patients. Hence this study was carried out to provide the first baseline data of clinical, hematological and biochemical profiles of patients infected with dengue virus. METHODS: A cross-sectional study was carried out among febrile patients in northwest Ethiopia from March 2016 to May 2017. Blood samples were collected from dengue presumed cases and tested against dengue specific IgM antibody by enzyme-linked immunosorbent assay (ELISA). Those study participants who fulfilled the inclusion criteria were enrolled in the study. Clinical examination findings were recorded, hematological and biochemical parameters tests were done. RESULTS: During the study period, a total of 102 dengue cases were included in the study. Of these, there were 16 (15.7%) children and 86 (84.3%) adults between 1 and 76 year age. The most common clinical presentations followed by fever (100%) were a headache 89 (87.3%), myalgia 82 (80.4%), nausea/vomiting 71 (69.6%). The common hematological findings were thrombocytopenia 61 (59.8%), followed by anemia 45 (44.1%) and leucopenia 27 (26.5%) and the elevated levels of biochemical parameters were AST 46 (45.1%) and ALT in 18 (17.6%). CONCLUSIONS: This study highlights the most common clinical and laboratory profiles of dengue viral infections that could alert physicians to the likelihood of dengue virus infections in the study area.

RESUMO

BACKGROUND: Many women die from complications related to pregnancy and childbirth. In developing countries particularly in sub-Saharan Africa and Asia, where access to emergency obstetrical care is often limited, obstetric fistula usually occurs as a result of prolonged obstructed labour. Obstetric fistula patients have many social and health related problems like urinary tract infections (UTIs). Despite this reality there was limited data on prevalence UTIs on those patients in Ethiopia. Therefore, the aim of this study was to determine the prevalence, drug susceptibility pattern and associated risk factors of UTI among obstetric fistula patients at Gondar University Hospital, Northwest Ethiopia. METHODS: A cross sectional study was conducted from January to May, 2013 at Gondar University Hospital. From each post repair obstetric fistula patients, socio-demographic and UTIs associated risk factors were collected by using a structured questionnaire. After the removal of their catheters, the mid-stream urine was collected and cultured on CLED. After overnight incubation, significant bacteriuria was sub-cultured on Blood Agar Plate (BAP) and MacConkey (MAC). The bacterial species were identified by series of biochemical tests. Antibiotic susceptibility test was done by disc diffusion method. Data was entered and analyzed by using SPSS version 20. RESULTS: A total of 53 post repair obstetric fistula patients were included for the determination of bacterial isolate and 28 (52.8%) of them had significant bacteriuria. Majority of the bacterial isolates, 26 (92.9%), were gram negative bacteria and the predominant ones were Citrobacter 13 (24.5%) and E. coli 6 (11.3%). Enterobacter, E.coli and Proteus mirabilis were 100% resistant to tetracycline. Enterobacter, Proteus mirabilis, Klebsella pneumonia, Klebsella ozenae and Staphylococcus aureus were also 100% resistant to ceftriaxone. CONCLUSION: The prevalence of bacterial isolates in obstetric fistula patients was high and majority of the isolates were gram negative bacteria. Even thought the predominant bacterial isolates were Citrobacter and E. coli, all of the bacterial isolates had multiple antibiotic resistance patterns which alert health profession to look better treatment for these patients.

RESUMO

Background: Globally, viral hepatitis is a leading cause of death and is highly prevalent in Ethiopia. Military personnel are more vulnerable to hepatitis B virus (HBV) and hepatitis C virus (HCV) infections, and there are no data on such populations in the study area. Therefore, this study aimed to determine the seroprevalence of HBV and HCV infections and their associated factors among military personnel in military camps in Central Gondar, Ethiopia. Materials and Methods: This institutional-based cross-sectional study was conducted with 277 military personnel from April to August 2022 at military camps in Central Gondar, Ethiopia. A systematic random sampling technique was used to select the study participants. Sociodemographic and other relevant data were collected using a structured questionnaire. Five milliliters of venous blood were collected using a vacutainer tube and tested for hepatitis B surface antigens and anti-hepatitis C virus antibodies using an enzyme-linked immunosorbent assay. Data were analyzed using STATA version 14 software and logistic regression models were used to determine the association between HBV/HCV infection and risk factors. Results: Out of 277 participants, the overall seroprevalence of HBV and HCV infections was 19 (6.9%) and 9 (3.3%), respectively. The rate of HBV and HCV co-infection was 2 (0.7%). Having multiple sexual partners (p = 0.048), frequent alcohol use (p = 0.034), hospitalization (p = 0.014), and history of receiving injections from traditional practitioners (p = 0.040) were significant predictors of HBV infection. In contrast, a history of blood transfusion (p = 0.048) and sexually transmitted infections (p = 0.039) were significant risk factors for HCV infection. Conclusion and Recommendations: An intermediate prevalence of HBV and HCV infections was observed among the military personnel. Continuous screening, adherence to healthcare service guidelines, and strengthening of vaccination are crucial for preventing HBV and HCV infections.

RESUMO

BACKGROUND: Norovirus (NoV) is the leading cause of diarrheal disease worldwide and the impact is high in developing countries, including Ethiopia. Moreover, there is a significant and fluctuating global genetic diversity that varies across diverse environments over time. Nevertheless, there is a scarcity of data on the genetic diversity of NoV in Ethiopia. OBJECTIVE: This study was aimed to assess the genetic diversity and distribution of NoVs circulating in the Amhara National Regional State, Ethiopia, by considering all age groups. METHODS: A total of 519 fecal samples were collected from diarrheal patients from May 01/2021 to November 30/ 2021. The fecal samples were screened for the presence of NoVs using real-time RT-PCR by targeting a portion of the major capsid protein coding region. The positive samples were further amplified using conventional RT-PCR, and sequenced. RESULTS: The positivity rate of NoV was (8.9%; 46/519). The detection rate of NoV genogroup II (GII) and genogroup I (GI) was 38 (82.6%) and 8 (17.4%), respectively. Overall, five distinct GII (GII.3, GII.6, GII.10, GII.17, and GII.21) and two GI (GI.3 and GI.5) genotypes were detected. Within the GII types, GII.3 was the predominant (34.2%) followed by GII.21 (15.8%), GII.17 (10.5%), GII.6 and GII.10 each (2.6%). Norovirus GII.21 is reported for the first time in Ethiopia. The genetic diversity and distribution of NoVs were significantly different across the four sampling sits and age groups. The phylogenetic analysis revealed close relatedness of the current strains with published strains from Ethiopia and elsewhere. CONCLUSION: The distribution and genetic diversity of NoV was considerably high, with predominance of non-GII.4 genotypes. The GII.21 genotype is a new add on the growing evidences on the genetic diversity of NoVs in Ethiopia. Future nationwide surveillance studies are necessary to gain comprehensive data in Ethiopia.

RESUMO

BACKGROUND: Children with under-five year age disproportionally affected with foodborne illness. Campylobacteriosis is the most common foodborne disease next to Norovirus infection. Macrolides are commonly prescribed as the first line of treatment for Campylobacter gastroenteritis, with fluoroquinolone and tetracycline as secondary options. However, resistance to these alternatives has been reported in various regions worldwide. OBJECTIVE: To determine the prevalence, associated risk-factors and antimicrobial resistance of Campylobacter jejuni and C. coli among under-five children with diarrhea. METHODS: Institution-based cross-sectional study was conducted from November, 2022 to April 2023. The study sites were selected using a random sampling technique, while the study subjects were included using a convenient sampling technique. The data were collected using a structured questionnaire. Stool samples were inoculated onto modified charcoal cefoperazone deoxycholate agar and incubated for 48 hours. The suspected colonies were analyzed using matrix-assisted laser desorption ionization-time of flight mass spectrometry to confirm the species. Antimicrobial susceptibility testing was performed using a disc diffusion technique. All potential covariates (independent variables) were analyzed one by one using bivariate logistic regression model to identify candidate variables with P value < 0.25. Multivariable logistic analysis was used to identify potential associated factors using the candidate variables. A p value ≤ 0.05 at a 95% confidence interval was statistically significant. RESULT: Among the 428 samples, 7.0% (CI: 4.5-9.3) were confirmed Campylobacter species. The prevalence of C. jejuni and C. coli among under-five children was 5.1% (CI: 3.0-7.0) and 1.9% (CI: 0.7-3.3), respectively. C. jejuni (73.3%) was dominant over C. coli (26.7%). The resident, contact with domestic animals, and parents/guardians education level were significantly associated with campylobacteriosis among under-five children. One-third of the Campylobacter isolates (33.3%, 10/30) were resistant to ciprofloxacin and tetracycline whereas 10.0% (3/30) were resistant to erythromycin. Furthermore, 3.3% (1/30) of the Campylobacter were found to be multidrug-resistant. CONCLUSION: The prevalence of Campylobacter species was 7.0%. The resistance rate of Campylobacter species of ciprofloxacin and tetracycline-resistance strains was 33.3%. Peri-urban residence, contact with domestic animals, and low parental educational statuses were significantly associated factors with increased risk of Campylobacter infection. Continuous surveillance on antimicrobial resistance and health education of personal and environmental hygiene should be implemented in the community.

RESUMO

BACKGROUND: Ear infection is a common problem for both children and adults especially in developing countries. However in Ethiopia particularly in the study area, there is no recent data that shows the magnitude of the problem. The aim of this study was to determine the bacterial isolates and their drug susceptibility patterns from patients who had ear infection. METHOD: A retrospective study was conducted from September, 2009 to August, 2012 at Gondar University Hospital, Northwest Ethiopia. Ear discharge samples were cultured on MacConkey agar, blood agar and chocolate agar plates. A standard biochemical procedure was used for full identification of bacterial isolates. Antimicrobial susceptibility tests were done on Mueller-Hinton agar by using disk diffusion method. Data were entered and analyzed by using SPSS version 20 software and P-value of < 0.05 was considered statistically significant. RESULT: A total of 228 ear discharge samples were tested for bacterial isolation and 204 (89.5%) cases were found to have bacterial isolates. From the total bacterial isolates, 115 (56.4%) were gram negative bacteria and the predominant isolate was proteus species (27.5%). Of individuals who had ear infection, 185 (90.7%) had single bacterial infection while 19 (9.3%) had mixed infections. Under five children were more affected by ear infection. The prevalence of ear infection was significantly high in males (63.7 vs 36.3%) (P = 0.017). Of all bacterial isolates, 192 (94.1%) had multiple antibiotic resistant pattern. Non Lactose Fermenter Gram Negative Rods (46.0%), Klebsella species (47.7%) and Pseudomonas species (48.5%) were resistant against the commonly used antibiotics. CONCLUSION: The prevalence of ear infection was very high in the study area. Majority of the bacterial isolates were resistant to multiple antibiotics. Hence antibiotics susceptibility test is mandatory before prescribing any antibiotics.

RESUMO

Background: Streptococcus pyogenes (S. pyogenes) or group A streptococcus is a common cause of bacterial pharyngitis in children. Since it is difficult to distinguish between viral and bacterial pharyngitis using solely signs and symptoms, culture-based diagnosis and treatment are critical for avoiding serious complications. Therefore, this study aimed to determine the prevalence, antimicrobial susceptibility patterns, and associated factors of S. pyogenes among pediatric patients with acute pharyngitis. Methods: A hospital-based cross-sectional study was conducted at the University of Gondar Comprehensive Specialized Hospital from April to June 2021. Standard microbiological procedures were used to collect and process throat swabs and to isolate and identify S. pyogenes. The disc diffusion method was used for antimicrobial susceptibility testing (AST). Results: A total of 215 children with acute pharyngitis were included in this study. Of these, 23 (10.7%) were culture positive for S. pyogenes. The presence of an inflamed tonsil, tonsillar exudate, scalariform rash, and dysphagia were associated with streptococcal pharyngitis. Children aged 5 to 15 were more susceptible to streptococcal throat infection than younger children. Penicillin, vancomycin, chloramphenicol, clindamycin, and ceftriaxone were effective against 100%, 95.7%, 95.7%, 91%, and 87% of isolates, respectively. In contrast, 56.5%, 39.1%, and 30.4% of isolates showed at least reduced susceptibility to tetracycline, erythromycin, and azithromycin, respectively. Conclusion: Streptococcus pyogenes is responsible for 10.7% of acute pharyngitis cases among pediatric patients in the study area. Although all isolates remain sensitive to penicillin, many showed reduced susceptibility to tetracycline and macrolides. Therefore, prior to antibiotic prescription, screening children with acute pharyngitis for S. pyogenes and testing the antibiotic susceptibility of isolates is recommended.

RESUMO

BACKGROUND: The high cost of CD4 count estimation in resource-limited countries is a major challenge in initiating patients on highly active antiretroviral therapy (HAART). Therefore, assessment of inexpensive and simple laboratory diagnostic marker is mandatory to diagnose immuno-suppression. OBJECTIVE: To evaluate utility of total lymphocyte count (TLC) as surrogate marker for CD4 count in HIV-infected patients. MATERIALS AND METHODS: In this cross sectional study, 400 ART-naive HIV-positive patients enrolled in Gondar University Hospital, from March 2011 to May 2011, were tested for CD4 count & TLC. The cutoffs were determined as: 200 cells/µL for CD4 count and 1200 cells/µL for TLC by using BD FACS count and CELL DYN 1800 Flow Cytometrys respectively. Spearman correlation between TLC and CD4 cell count were assessed. Sensitivity, specificity, positive and negative predictive values for different age a group, TLC ≤1200 was computed for CD4 count ≤200 cells/cu.mm. RESULTS: Among 400 ART naive HIV infected patients, 278 (69.5%) were females. The mean age of the study participants was 33.7. TLC and CD4 count were positively correlated (r = 0.33, p = 0.001). A TLC of ≤1200 cells/m m3 was found to have a sensitivity (32.86%), specificity (95.33%), PPV (79.7%), and NPV (71.9%) for predicting a CD4 count of <200 cells/mm3. CONCLUSION: This study showed that low sensitivity and specificity of TLC as a surrogate measure for CD4 count. Moreover, CD4 cell counts of < 200 cells/mm3 were found in 96 cases (24%) with TLCs of ≤1200 cells/mm3. Thus, 1 in 4 individuals would have been deprived of needed treatment. Therefore, we recommend keep on expansion of access to CD4 counter.

RESUMO

BACKGROUND: Hepatitis B virus (HBV) and hepatitis C virus (HCV) are hepatotropic viruses whose primary replication occurs in the liver. Despite the significant clinical importance of early screening of hepatitis B and C virus infection in decreasing the hepatotoxicity effect of anti-tuberculosis drugs, screening of hepatitis B and C virus among tuberculosis (TB) patients before treatment has not been practiced in Ethiopia. Thus, this study was conducted to determine the seroprevalence and associated factors of HBV and HCV infections among pulmonary TB (PTB) patients attending health facilities in Gondar, Northwest Ethiopia. METHODS: A cross-sectional study was conducted among 145 bacteriologically confirmed PTB patients from January 1 to May 30, 2019. After obtaining a signed informed consent from each participant, data on socio-demographic, clinical, and associated factors were collected using a structured pre-tested questionnaire. Besides, a blood sample was collected to determine HBsAg and HCV antibodies by enzyme linked immune sorbent assay (ELISA). The data were entered and analyzed using SPSS version 21. A Fisher's exact test was used to see the relationship between dependent and independent variables, and a p-value ≤0.05 was considered as statistically significant. RESULTS: Out of the 145 PTB patients screened, 5 (3.4%) patients tested positive for HBsAg, yet none of them were found to be positive for anti-HCV. Besides, the proportion of HIV-positive was 12 (8.3%). History of hospital admission (P= 0.005), tattooing (P= 0.009) and dental extraction (P=0.003) were significantly associated with HBsAg. CONCLUSION: Although anti-HCV antibodies were not detected, the prevalence of HBV was relatively high in tuberculosis patients. This study highlights the need for the introduction of routine screening of viral hepatitis markers for all TB patients before anti-TB treatment for better management of patients. Likewise, further clinical and epidemiological studies are needed.

RESUMO

BACKGROUND: Chikungunya virus (CHIKV) infection has similar clinical presentations to malaria. Hence, febrile illnesses are often misdiagnosed as malaria. Therefore, this study aimed to generate baseline data on CHIKV infection in northwest Ethiopia where malaria is endemic. METHODS: A hospital-based cross-sectional study was conducted among febrile patients presenting at the Metema and Humera Kahsay Abera hospitals from March 2016 to May 2017. Data on socio-demographic, clinical presentations, and possible risk factors were collected using a structured questionnaire. Serum samples were screened for immunoglobulin-M (IgM) and IgG antibodies to CHIKV infections using enzyme-linked immunosorbent assay. Logistic regression analysis was used to determine the strength of association. RESULTS: Of 586 samples screened, the overall seroprevalence of CHIKV infection was 23%. Of the total study participants, 22.5% had CHIKV-specific IgM, indicating recent CHIKV infection. During monsoon and post-monsoon periods, increased prevalence of anti-CHIKV IgM seropositivity was found. The most common clinical presentation observed was fever, followed by headache and joint pain. Men had twice the likelihood of CHIKV infection. The presence of stagnant water near the residence almost doubled the risk for CHIKV infection. CONCLUSIONS: Most of the study participants had recent infection with CHIKV, suggesting the need to design disease prevention and intervention strategies.

RESUMO

OBJECTIVE: Intestinal parasites are present throughout the world in varying degrees of prevalence due to many factors. The aim of this study was to determine the 5-year trend prevalence of intestinal prevalence among patients who had been suspected for intestinal parasite infections. A retrospective study was conducted from 2009 to 2013 at Poly Health Center Gondar, Northwest Ethiopia. Samples were examined using direct saline wet mount methods. Statistical analysis was done using SPSS version 20 software and a P-value of < 0.05 was considered statistically significant. The results were presented in tables and graphs. RESULTS: During the study period, a total of 13,329 stool samples were requested for intestinal parasite diagnose and 5510 (41.3%) laboratory-confirmed cases were reported with a fluctuating trend. Ten different parasites were reported in each year with Entamoeba histolytica/dispar (16.8%) being the predominant parasite followed by Giardia lamblia (11.4%) and Ascaris lumbricoides (6.7%). Both males (49%) and females (51%) were equally affected (P = 0.14). The intestinal parasite was reported in all age groups in the area but the highest and the lowest prevalence were reported in age groups of 20-29 years and 40-49 years, respectively (26.5% vs 6.4%) (P < 0.001).

RESUMO

OBJECTIVE: Although typhoid fever is a major public health problem in Ethiopia, data is not available in the study area. Therefore, this study aimed to determine the prevalence, clinical presentation at the time of diagnosis and associated factors of typhoid fever among febrile patients visiting Shashemene Referral Hospital, southern Ethiopia. A cross-sectional study was conducted from January 1, 2016, to October 30, 2016. Socio-demographic and clinical data were collected using a structured questionnaire. A blood sample was collected and inoculated into Tryptic soy broth. RESULTS: A total of 421 adult febrile patients suspected of typhoid fever were included in the study. Of these, the overall prevalence of culture-confirmed typhoid fever was 5.0% (21/421). The prevalence of typhoid fever was significantly associated with rural residence (8.4%). As compared to the urban resident, the rural resident was 3.6 times more likely found to have culture-confirmed typhoid fever. The prevalence of typhoid fever was significantly associated with those patients whose water source was spring 7 (12.3%) and river 7 (13.2%). All of those study participants who used treated water were culture negative. Fever for ≥ 5 days, abdominal pain, and skin rash independently predicted blood culture-confirmed typhoid fever.

RESUMO

BACKGROUND: Rubella virus infection in early pregnancy lead to serious multi-organ birth defects known as congenital rubella syndrome (CRS). The incidence of CRS varies in different populations and the highest burden is found in developing countries in which rubella vaccination is not included in their national immunization programs. In Ethiopia, there is scarcity of data about congenital rubella syndrome. Therefore, the aim of this study was to determine the burden of CRS-related birth defects and its incidence in the pre-vaccine era in Amhara Regional State, Ethiopia. MATERIALS AND METHODS: A cross sectional study was conducted in Dessie, Felege-Hiwot and University of Gondar Referral Hospitals, from December 2015 to August 2017. After getting informed assent from each parent/guardian, blood was collected from infants < 1 year of age for laboratory determination of anti-rubella virus antibodies. Their socio-demographic data and clinical information compatible with congenital rubella syndrome were collected using WHO guideline. RESULTS: During the study period, a total of 50 infants suspected for congenital rubella syndrome were included in the study. All infants suspected for CRS were tested against rubella specific IgM and IgG [for infants ≥ 6 months of age] antibodies using ELISA method. Of these, 9/50 (18%) and 4/14 (28.6%) of them were laboratory confirmed and potential CRS cases, respectively. In the present study, the most common laboratory confirmed defect was ocular manifestations 6 (66.7%) followed by heart related problems 5 (55.6%). In the present study, most of the laboratory confirmed cases (66.7%) were reported among 1-5 months of age infants. In addition, 5 (55.6%) of the infants with laboratory confirmed CRS cases were male and 6 (66.7%) of them were from urban settings. In this study, the incidence of CRS was 0.4 per 1000 live births. CONCLUSION: In this study, nearly one fifth of the infants had laboratory confirmed congenital rubella syndrome and most of them had multiple rubella associated congenital defects at a time. Most of these congenital anomalies were reported among infants ≥ 1 month of age. Based on our result, the incidence of the CRS was line with the global incidence of the CRS in the pre-vaccine era. Therefore, establishing strong rubella/CRS surveillance system as well as introducing the rubella containing vaccine in the national immunization program might be important to reduce the burden of rubella and CRS in the country.

RESUMO

OBJECTIVE: Malaria and human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) are the major medical challenges of priority faced by the sub-Saharan African countries in general and Ethiopia in particular. Thus, the aim of this study was to determine the prevalence and associated risk factors of HIV and malaria infections among febrile illness patients. METHODS: A cross-sectional study was conducted from November 1, 2014 to May 30, 2015 at Kolla-Diba Health Center, Northwest Ethiopia. After obtaining informed consent, blood samples were collected from each febrile patient for the laboratory determination of HIV and malaria infections. Sociodemographic data and other associated factors for HIV and malaria infections were collected using a structured questionnaire. RESULTS: Of the total of 384 febrile illness patients, 23.7% (91/384) were positive for Plasmodium species. Of these, the most prevalent was P. falciparum, 56.0% (51/91), followed by Plasmodium vivax infection, 38.5% (35/91). In this study, 13.8% (53/384) of the participants were positive for HIV. Furthermore, 3.13% (12/91) of the participants were coinfected with HIV and malaria. According to the findings of the present study, genital ulcer patients and those who do not use bed net were significantly associated with HIV and malaria infections, respectively. CONCLUSION: Malaria and HIV are still common challenges independently occurring in the study area. The coexistence of the two diseases cannot be underestimated. Hence, health professionals should strengthen the provider initiative counseling and testing (PICT) program as a means of HIV/AIDS prevention and control strategy. Furthermore, approaching the febrile illness patients for both malaria and HIV diagnoses may help in having a joint HIV and malaria prevention and control strategy.

RESUMO

BACKGROUND: Hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) positive mother has up to 90% likelihood of mother-to-child transmission (MTCT) of hepatitis B virus (HBV) to newborns in the absence of any prophylaxis or antiviral therapy utilization. However, routine antenatal screening and intervention strategies are not yet practiced in Ethiopia. Therefore, this study was conducted to determine the prevalence, infectivity, and associated risk factors of HBV among pregnant women. METHODS: A cross-sectional study was conducted from October 2015 to August 2016 in Yirgalem Hospital. A total of 475 pregnant women were recruited, and data on sociodemography and potential risk factors were collected using a structured questionnaire. In addition, blood samples were tested for HBsAg, and HBsAg positive samples were retested for HBeAg using commercially available strip test. The status of HIV was collected from the records. RESULTS: The seroprevalence of HBsAg was 34 (7.2%), of whom 13 (38.8%) were positive for HBeAg. The prevalence of HIV infection was 10.1% (48/475). Ten out of 34 HBV positive cases (29.4%) were coinfected with HIV. The overall HBV/HIV coinfection rate was 2.1% (10/475). Women with history of multiple sexual partners and being HIV positive were significantly associated with HBsAg positivity. Among the study participants, 35.4% were aware of MTCT of HBV and only 12 (2.5%) have taken HBV vaccine. CONCLUSIONS: High prevalence of HBsAg and HBeAg as well as low awareness and practices of HBV prevention methods suggests that perinatal transmission of HBV might be the prevailing mode of HBV transmission in the study area. Thus, screening of all pregnant women, particularly those who had history of multiple sexual partners and HIV coinfection, and provision of health education about HBV prevention methods are inevitable.
