RESUMO

Campylobacteriosis disproportionately affects children under five in low-income countries. However, epidemiological and antimicrobial resistance (AMR) information at the children-animal interface is lacking. We hypothesized that Campylobacter is a major cause of enteritis in children in Ethiopia, and contact with animals is a potential source of transmission. The objective of the study was to determine Campylobacter occurrence and its AMR in children under five with diarrhea, backyard farm animals, and companion pets. Stool from 303 children and feces from 711 animals were sampled. Campylobacter was isolated through membrane filtration on modified charcoal cefoperazone deoxycholate agar plates under microaerobic incubation, and the technique showed to be feasible for use in regions lacking organized laboratories. Typical isolates were characterized with MALDI-TOF MS and multiplex PCR. Of 303 children, 20% (n = 59) were infected, with a higher proportion in the 6 to 11-month age group. Campylobacter occurred in 64% (n = 14) of dogs and 44% (n = 112) of poultry. Campylobacter jejuni was present in both a child and animal species in 15% (n = 23) of 149 households positive for Campylobacter. MICs using the gradient strip diffusion test of 128 isolates displayed resistance rates of 20% to ciprofloxacin and 11% to doxycycline. MICs of ciprofloxacin and doxycycline varied between C. coli and C. jejuni, with higher resistance in C. coli and poultry isolates. Campylobacter infection in children and its prevalent excretion from backyard poultry and dogs is a understudied concern. The co-occurrence of C. jejuni in animals and children suggest household-level transmission As resistance to ciprofloxacin and doxycycline was observed, therapy of severe campylobacteriosis should consider susceptibility testing. Findings from this study can support evidence-based diagnosis, antimicrobial treatment, and further investigations on the spread of AMR mechanisms for informed One Health intervention.

RESUMO

BACKGROUND: Catheter-associated urinary tract infections (CAUTIs) due to multidrug-resistant Gram-negative bacilli (GNB) is a common concern globally. Investigating the incidence of CAUTI and associated antibiotic resistance has paramount importance from the health care associated infections perspective. This study therefore assessed the incidence of CAUTIs due to GNB and the production of extended-spectrum beta-lactamase (ESBL) and carbapenemase among inpatients in specialized hospitals of Northwest, Ethiopia. METHODS: A total of 363 patients with indwelling urinary catheters who were admitted in the hospital for > 48 h were consecutively enrolled and followed from 3 to 18 days. Data were collected through interviewing and review of medical records. Patients who developed at least one of the following: fever (> 38 OC), suprapubic tenderness, or costovertebral angle pain, coupled with a GNB positive urine culture of ≥ 103 CFU/mL with no more than two bacterial species were defined as CAUTI. The ESBL and carbapenemase production were detected and identified by chromogenic medium. Logistic regression analysis was done to identify associated factors. RESULTS: From 363 patients followed, the incidence rate of CAUTI was 27.8 per 1000 catheter days. Catheterization for ≥ 8 days (AOR = 10.6, 95%CI:1.8-62.1) and hospitalization for > 10 days (AOR = 8.1, 95%CI: 2.4-27.2) were the factors significantly associated with CAUTIs. E. coli (n = 18, 34.6%), Proteus species (n = 7, 13.5%), and P. aeruginosa (n = 6, 11.5%) were the most frequent GNB. Isolates revealed high rates of resistance to amoxicillin-clavulanic acid (100%), cefazolin (n = 51, 98%), ceftazidime (n = 47, 90%) and cefotaxime (n = 46, 88%). Most of the GNB isolates (86.5%) were multidrug-resistant. Overall, 19.2% and 5.8% of GNB isolates were ESBL and carbapenemase producers, respectively. CONCLUSIONS: Incidence of CAUTI with Gram-negative bacilli is high. As most of the GNB isolates are MDR and showed a super high rate of resistance to amoxicillin-clavulanic and third-generation cephalosporins, empirical treatment with these substances is virtually ineffective in patients with suspected GNB infection in Ethiopia. The expression of ESBL and carbapenemase among GNB isolates is also a concern. Therefore, improved infection prevention and control measures, careful use of catheters and third generation of cephalosporins are needed to improve patient outcomes and reduce the burden of CAUTIs and the spreading of antimicrobial resistance.

RESUMO

Introduction: Tonsillitis is the third most frequently diagnosed infection in the pediatric age and is associated with significant morbidity and loss of school attendance. Throat swab cultures are useful for the confirmation of children with a clinically suspected tonsillitis. However, Somaliland is one of the underdeveloped countries with a low standard of sanitation and poor health seeking culture. Treatment of tonsillitis with antibiotics is irrational and not empirical. This study determined the bacterial throat swab culture positivity and antibiotic resistance profiles of the bacterial isolates among children 2-5 years of age with suspicion of tonsillitis at Hargeisa Group of Hospital, Somaliland. Materials and Methods: A cross-sectional study was conducted from March to July 2020. A total of 374 children from 2 to 5 years of age suspicion of tonsillitis was included using a convenient sampling method. Throat swabs were collected, and bacterial isolation and identification were done using standard bacteriological procedures. Antimicrobial susceptibility testing was done using the disk diffusion method. Data on demographic variables and clinical profiles were collected using structured questionnaires. Logistic regression analysis was computed to identify factors associated with bacterial tonsillitis. Results: Overall, 120 (32.1%) (95% CI 27.4-36.8%) of children were positive for bacterial throat cultures. Of these, 23 (19.2%) were mixed bacterial isolates. The most frequent bacterial isolates were beta-hemolytic streptococci 78 (55%), Staphylococcus aureus 42 (29%), and Streptococcus pneumoniae 10 (7%). Isolates revealed 83.3-100% rate of resistance to ampicillin. Beta-hemolytic streptococci isolates were 94.9% resistant to ampicillin. S. aureus was resistant to clarithromycin (38%) while S. pneumoniae isolates were 100% resistant to ampicillin. History of tonsillitis (AOR = 0.12; 95% CI = 0.06-0.21), difficulty in swallowing (AOR = 6.99; 95% CI = 3.56-13.73), and attending schools (AOR = 2.98; 95% CI = 1.64-5.42) were found to be associated with positive throat culture. Conclusions: Resistance to ampicillin and MDR among beta-hemolytic streptococci and other isolates of throat colonizers in children with clinically suspected of bacterial tonsillitis are major concerns in Hargeisa, Somaliland. Therefore, treatments of cases are recommended to be guided by regular culture and antimicrobial susceptibility testing to prevent complications of tonsillitis and associated antibiotic resistance.

RESUMO

BACKGROUND: World Health Organization identified some Enterobacteriaceae as superbugs because of their high production and spread of extended-spectrum beta-lactamases (ESBL) and carbapenemases. Moreover, their resistance against commonly prescribed antibiotics left few choices of drugs to treat infection. This study is aimed at determining the magnitude of ESBL and carbapenemase-producing Enterobacteriaceae pathogens and their antimicrobial resistance pattern. MATERIALS AND METHODS: A hospital-based cross-sectional study was carried out from February to April 2019 in the Northwestern Ethiopia region. A total of 384 patients presumptive for bacterial infections were conveniently enrolled in the study. Specimens were collected and processed following standard bacteriological procedures. Drug susceptibility tests were performed using disk diffusion technique. ESBL and carbapenemase enzymes were tested by double disk diffusion and modified carbapenem inhibition methods, respectively. The data obtained were analyzed using SPSS version 22 software, and descriptive statistics were summarized in tables and graphs. RESULTS: Out of 384 clinical specimens processed 100 (26%) were culture positive for Enterobacteriaceae. The proportion of Enterobacteriaceae infection was relatively higher among in-patients 86 (32.6%) than out-patients 14 (11.7%). Overall, Escherichia coli 35 (9.1%) was the leading isolate followed by Klebsiella pneumoniae 31 (8.1%). Klebsiella pneumoniae 15 (15.6%) was the most frequent isolate from bloodstream infection and is the leading isolate from intensive care unit patients 15 (38.3%). Overall, 44 (44%) of Enterobacteriaceae were extended-spectrum beta-lactamase producers. Among them, Citrobacter spp. was the leading one 4 (80%) followed by Enterobacter cloacae 6 (60%) and K. pneumoniae 18 (58.1%). Furthermore, 6 (6%) of Enterobacteriaceae were carbapenemase-producers, in which 5 (50%) of E. cloacae and 3 (9.7%) of K. pneumoniae had highest percentage. Conclusions. ESBL and carbapenemase-producing isolates of Enterobacteriaceae are alarmingly spreading in the study area. Thus, improving the infection prevention strategy and further screening at the national level is recommended to develop the optimal use of antibiotics.

RESUMO

BACKGROUND: Group B streptococci (GBS) is an important pathogen involved in stillbirths, neonatal deaths and neurological defects, and the occurrence of multi-drug resistance (MDR) is an alarming issue. This study determined the prevalence of GBS colonization in pregnant women and newborns, the proportion of vertical transmission, antimicrobial susceptibility profiles of isolates, and the factors associated with colonization and vertical transmission. METHODS: A cross-sectional study was conducted from March 1, 2021 to June 30, 2021, at selected health facilities of Bahir Dar city. Vaginal-recto swabs from 292 pregnant women and pooled ear, nasal and umbilical swabs from 292 newborns were collected. GBS were identified following standard microbiological protocols. Antimicrobial susceptibility testing was performed using modified Kirby-Bauer disk diffusion method and interpreted by the accepted 2020 CLSI M100 guidelines. Logistic regression analysis was computed. RESULTS: Overall, 54 (18.5%) of pregnant women and 22 (7.5%) of newborns had GBS colonization. The proportion of GBS vertical transmission was 22 (40.7%). Group B Streptococcus isolates scored susceptibility to penicillin, ampicillin and vancomycin with 88.9%, 90.7%, and 96.3% for pregnant women and 86.4%, 90.9% and 95.9% for newborns, respectively. A high percentage of non-susceptibility was found for clindamycin and erythromycin with 33.3% and 25.9% for pregnant women and 31.8% and 22.7% from newborns, respectively. Besides, 19 (35.2%) GBS from pregnant women and 8 (36.4%) from newborns were MDR. Group B streptococci colonization was significantly associated with delivery before 37th week of gestation (AOR=2.77, 95% CI 1.14-6.68) and history of stillbirth (AOR=3.13, 95% CI 1.13-8.70). CONCLUSION: Pregnant women vaginal-recto GBS colonization and transmission to newborns connected with MDR are a matter of concerns. Although non-susceptible GBS isolates are obtained, penicillin and vancomycin are relatively effective. The use of clindamycin, erythromycin and ceftriaxone should be guided by antimicrobial susceptibility testing. Genetic analysis is recommended to exactly identify the epidemiology of GBS strains, vertical transmission and antimicrobial resistance at the country level.

RESUMO

BACKGROUND: Infections with multi-drug resistant (MDR) bacteria are serious threats to many low-income countries associated with overuse and misuse of antibiotics. This study determined the antibiogram profiles of bacteria isolated from different body site infections among patients admitted to GAMBY Teaching General Hospital, Bahir Dar, Northwest Ethiopia. METHODS: A hospital-based cross-sectional study was done between November 2015 and May 2018. Various clinical specimens were sampled from patients and analyzed for aerobic bacterial isolation and Kirby-Bauer disk diffusion susceptibility testing. Chi-square test was calculated to see association among variables, and P-value <0.05 was taken as a cutoff value for statistical significance. RESULTS: From the 716 clinical specimens processed, 134 (18.7%) were culture-positive for aerobic bacterial pathogens. Culture-confirmed positivity was higher in ear discharge (27.3%) and urine (26.3%) samples. The prevalence of infection was significantly highest among females (P = 0.001). Escherichia coli 63 (47.4%) and 10 (7.4%) of Klebsiella spp. from Gram-negative bacteria were the predominant bacterial isolates, while Staphylococcus saprophyticus 17 (12.6%) and S. aureus 14 (10.4%) were from Gram-positive bacteria. Overall, 61.8% of the isolates were found to be MDR. The proportion of MDR among Klebsiella spp., S. aureus and E. coli isolates was 90.9%, 60.9% and 50%, respectively. Gram-positive bacteria demonstrated 20%, 48.6% and 100% of resistance against norfloxacin, ciprofloxacin and clindamycin, respectively. Gram-negative bacteria also revealed from 20% resistance for the antibiotic nitrofurantoin and 100% of resistance for ampicillin and penicillin. CONCLUSION: Infections with bacterial isolates resistant to the majority of antibiotics are a major issue in the study area. Most of the identified bacteria were resistant to the routinely used antibiotics, and MDR isolates are alarmingly high. Therefore, clinicians should practice rational choice of antibiotics and treatment should be guided by antimicrobial susceptibility testing.

RESUMO

INTRODUCTION: Typhoid fever (TF) is a febrile global health problem caused by Salmonella enterica serovar Typhi (S. Typhi) with relatively high prevalence in low- and middle-income countries including Ethiopia. Identifying local prevalence and gaps in knowledge, attitude, and practice (KAP) towards TF is recommended by the World Health Organization to implement preventive measures. Therefore, this study determined the prevalence of S. Typhi and KAP of febrile patients towards TF in Injibara General Hospital, Northwest Ethiopia. METHODS: Hospital-based cross-sectional study was conducted from January to March 2020. A total of 237 patients were included conveniently. Data on KAP and demographic variables were collected using a structured questionnaire by face-to-face interview. After the interview, 5 ml venous blood was collected and processed using the Widal test following the manufacturer's instruction. Mean scores and percentages were used to determine the level of KAP. Multivariable analysis was done to correlate KAPs with TF. P value < 0.05 was considered statistically significant. RESULTS: The overall prevalence of S. Typhi was 25.7%. The highest seroprevalence was observed among the age group of 30-34 years (33.3%) and patients with no education. The majority of participants know the major ways of TF transmission (59.1-90.7%) and prevention (81.4%) methods. However, the misconception on the route of TF transmission was observed in 13.5-36.7% of participants. About 65.4% and 67.5% of study participants were considered knowledgeable and had good preventive practice towards TF, respectively. Being a student (AOR = 0.227, CI = 0.053 - 0.965) and considering mosquito bite as transmission routes (AOR = 2.618, CI = 1.097 - 6.248) were significantly associated with TF. CONCLUSION: High S. Typhi prevalence was observed in the study area. Moreover, the misconception on the transmission of typhoid fever and educational level was a risk factor for TF. Thus, health facilities should incorporate topics on typhoid fever as part of their health education system within health facilities and in the community.

RESUMO

BACKGROUND: Ocular infections are a serious public health problem in Ethiopia with increased incidence of morbidity and blindness. Empirical therapy with topical ophthalmic broad spectrum antibiotic formulations is also a prevailing practice. The aim of this study was to determine the bacterial causes of external ocular infections (EOIs), antimicrobial resistance and its associated risk factors among patients at Felege Hiwot Referral Hospital, Northwest Ethiopia. METHODS: A hospital based cross - sectional study was conducted from 1 February to 30 April 2019. Patients with EOIs were consecutively included from 1 February to 30 April, 2019. Data were collected using structured questionnaire by face-to-face interview and complemented with patient card review. Conjunctival, eyelid margin and lacrimal sac swabs were collected aseptically. Bacterial species were identified using standard bacteriological techniques. Antimicrobial susceptibility testing was done using Kirby-Bauer disk diffusion method. Binary logistic regression analysis was calculated to identify the factors associated with EOIs. P.value (p) < < 0.05 was considered as statistically significant. RESULTS: A total of 360 patients took part in the study and majority of them were males (64.7%). The median age of study participants was 59.5 years. Overall, 208(57.8%) (95%CI = 52.6- - 62.8%) of patients had culture confirmed bacterial EOIs. The proportion of culture confirmed EOIs was 60.4% among conjunctivitis cases and 55.8% among blepharitis. Ocular trauma (P < < 0.001), ocular disease (P < < 0.001) and having eye allergy (P = 0.027) were significantly associated with EOIs. The most frequent isolates were S. aureus (37%), K. pneumoniae (13.5%), Proteus(7.2%) spp., S. pneumoniae (4.3%), Citrobacter spp. (3.4%) and P. aeruginosa (2.9%). Gram positive isolates were resistant to penicillin in 87% and ampicillin in 86.2%. Gram negative isolates were resistant to ampicillin (87.5%). P.aeruginosa isolates (85.3%) were resistant to piperacillin and 50% were resistant to tobramycin. Overall, 45.2% of the isolates were multi-drug resistant. The percentage of multi-drug resistance was 80% among Enterobacter isolates and 64.3% among K. pneumoniae. CONCLUSIONS: Bacterial external ocular infections linked with multi-drug resistance and resistance to penicillin, ampicillin, tetracycline and piperacillin are high. Therefore, empirical treatment of eye infections in the study area needs to be monitored by regular antimicrobial-susceptibility testing of isolates.

RESUMO

BACKGROUND: Owing to the specific risk profile of its residents, intensive care units (ICUs) are the best place for selection pressure and the epicenter for resistance development and dissemination. Infections with ß-lactamase releasing Gram-negative bacilli (GNB) at ICUs are an emerging global threat. This study dogged the magnitude of extended-spectrum ß-lactamase (ESBL) and carbapenemase releasing Gram-negative bacilli infections and associated factors among patients in the ICUs of Felegehiwot Referral Hospital, Ethiopia. METHODS: A cross-sectional study was done through February to June 2020. Wound swabs, urine, blood and sputum samples were collected from patients in the ICUs symptomatic for infections while excluding those under coma and shock. Bacterial species were verified using standard microbiological methods. Carbapenemase and ESBL production were identified using modified carbapenem inactivation and combined disk diffusion methods, respectively. Multivariable analysis was calculated for factors associated with ESBL production. P-value < 0.05 was taken as cut-off for statistical significance. RESULTS: Out of 270 patients in the ICU, 67 (24.8%) and 14 (5.2%) had infections with ESBL and carbapenemase releasing GNB, respectively. The most frequent ESBL producing isolates were P. aeruginosa (100%), E. cloacae (100%), K. pneumoniae (82.8%) and E. coli (64%). The predominant carbapenemase producer isolates were K. pneumoniae (27.6%) and E. cloacae (33.3%). Overall, 77 (81.1%) of species were multi-drug resistant. All GNB species were 100% resistant to tetracycline and ampicillin. They are also resistant to cefuroxime, ceftazidime, sulfamethoxazole-trimethoprim and cefotaxime. Prior hospitalization (AOR = 5.5, CI = 2.63-11.46), support with medical care devices (AOR = 23.7, CI = 4.6-12) and arterial intravenous catheterization (AOR = 2.7, CI = 1.3-5.3) had significant association with ß-lactamase producing GNB infection. CONCLUSION: Infection with ESBL and carbapenemase producing Gram-negative bacilli linked with an alarming degree of multi-drug resistant isolates is a major healthcare threat among patients in ICUs. Hence, strict adherence to infection prevention practices and wise use of antibiotics are recommended to slow the spread of antimicrobial resistance.

RESUMO

BACKGROUND: Antibiotic resistant bacteria particularly extended-spectrum beta lactamase (ESBL) producing are of major concern for management of outpatients. They can spread rapidly and are associated with poor patient outcome. However, there is scarcity of information on ear infection with ESBL producing bacteria in Ethiopia. Therefore, this study investigates the prevalence of ear infection with ESBL producing bacteria among outpatients attending Felegehiwot Referral Hospital, Northwest Ethiopia. METHODS: A hospital based cross-sectional study was conducted from May, 2018 to January, 2019. Demographic and clinical data were collected with face to face interview and were complemented with patient card review. Ear discharge specimens were collected from study participants using swab technique. All ear swab specimens were cultured using standard microbiological techniques. The ESBL producing bacteria were detected by double disc synergy test and interpreted based on Clinical and laboratory Standards Institute Guidelines. Chi-square and fisher's exact tests were calculated to check association between variables. RESULTS: A total of 236 patients (male = 138 and female = 98) with ear infection took part in the study. The median age of the participants was 20years. Overall, 10 (4.23%, 95%CI; 2.3-7.6%) of patients had ear infection with ESBL producing bacteria. Other chronic illnesses (p = 0.003), history of hospital visit and treatment (p = 0.006) and history of antibiotic use without physician's prescription (p<0.001) had significant association with prevalence of ESBL producing bacteria in ear infection. The proportion of ear infection with ESBL producing P.mirabilis, P.aeruginosa and K.pneumoniae were 4 (1.7%), 3 (1.3%) and 2 (0.8%), respectively. All ESBL producing isolates were MDR (100%). Overall, 58 (43%) species were MDR. P.aeruginosa was the leading MDR isolate 29 (53.7%).For all bacterial isolates of ear infection, ampicillin(93.3%) and amoxicillin-clavulanic acid (58.5%) revealed high level of resistance whereas low resistance rates were observed for ciprofloxacin (5.2%), third generation cephalosporin (11.9-20%) and aztreonam (16.3%). CONCLUSIONS: Ear infection due to ESBL producing bacteria coupled with high levels of MDR is becoming a growing concern for outpatients in the study area. Regular detection of these bacteria and wise use of antibiotics are needed to stop the spread of this form of resistance.

RESUMO

BACKGROUND: Intestinal parasitic infections are the major causes of morbidity and mortality in sub-Saharan countries. The disease burden of these parasites is significantly high among pregnant women in developing countries like Ethiopia. Poor living conditions, sanitation, and hygiene are believed to be the contributing factors. The aim of this study was to determine the magnitude of intestinal parasitic infection and factors associated with pregnant women. METHODS: A cross-sectional study was conducted from February 2017 to June 2017. A structured questionnaire was used to obtain the sociodemographic and other explanatory variables via face-to-face interviews. Stool samples were collected and examined using formol ether concentration technique. The magnitude of parasitic infection was calculated using descriptive statistics. The association between intestinal parasitic infection and determinant factors was assessed by logistic regression. The differences were considered to be statistically significant if the p value was less than 0.05. RESULTS: From a total of 743 pregnant women, the overall prevalence of intestinal parasitosis was 277 (37.3%). The prevalence of hookworm 138 (18.6%) was the leading cause of intestinal parasitosis followed by E. histolytica/dispar 113 (15.2%). Dwelling in rural area (AOR: 2.9 (95% CI: 1.85-4.85)), being a farmer (AOR: 1.91 (95% CI: 1.20-3.03)), eating raw vegetables (AOR: 1.45, 95% CI:0.09-0.24), lack of proper use of latrine (AOR: 2.89 (95%1.18-7.08)), poor environmental sanitation (AOR: 0.19 (95%: CI:0.08-0.47)), habit of soil eating (AOR: 0.42 (95% CI: 0.25-0.72)), having irrigation practice (AOR: 0.47 (95% CI: 0.29-0.77)), and lack of health education (AOR: 0.32 (95% CI: 0.13-0.77)) were significantly associated with intestinal parasitic infections. CONCLUSIONS: Intestinal parasitic infection is a major problem among pregnant women in the study area. High parasitic infection is associated with poor hygienic and sanitation practices. Therefore, awareness creation through health education should be given to pregnancy on intestinal parasitic infection and associated factors.

RESUMO

BACKGROUND: Even though there are different tuberculosis (TB) prevention and control measures implemented globally including Ethiopia, TB is still major public health problem. This is partly due to compromised quality of care delivered for tuberculosis patients in health facilities (HFs) during diagnosis, treatment and follows-up. Thus this study is intended to determine the quality of care delivered for TB patients in all public HFs of Debre Tabor town, Northwest Ethiopia. METHODS: Cross sectional study was conducted from January to May 2018. Data were collected with face-to-face interview and TB registration book review using structured questionnaire and checklist respectively. Collected data was entered and processed using SPSS and P value <0.05 was considered statistically significant. The quality of care for each HF was graded as very good, good, moderate, poor and very poor if HFs achieve [90-100%], [80-90%), [70-80%), [60-70%) and <60% of performance indicators respectively using Donabedian structure, process and outcome model of health care quality. RESULTS: All HFs have sputum collection area, enough microscopic slide, at least one functional microscope and sufficient anti TB drug supply. But HFs lack backup laboratory stains. Overall structural aspects of quality of care in all HFs were very poor achieving 42.5-52.9% structural performance indicators out of 100%. Similarly the overall process aspects of quality of care was poor in all public HFs which achieved 60-68.9% of the scores out of 100%. In the study; 68.9%, 54.5% and 80.6% of Medical Laboratory, pharmacy and other healthcare workers (HWs) provided correct response respectively on TB causative agent, risk factor, transmission, treatment, prevention, case management and case finding strategies. HWs who knew at least two TB case finding strategies in DTH was significantly higher than those HWs working in Health Centers (P = 0.004). On the other hand, except Ginbot 20 HC, HFs was graded as good by scoring 86.6-89.3% of performance indicators on the outcome aspects of quality of care. In all HFs studied, all TB patients' unit TB registration number, sex, age, TB category, treatment initiation date and intensive phase treatment start year were properly registered. Moreover 110 (78%) and 147 (69%) contact person address in DTH and HCs was properly registered on TB unit register book respectively with no statistical difference in hospital and HCs (P = 0.063). There was proper TB patients' address registration in hospital than HCs studied (P< 0.001). CONCLUSIONS: The outcome aspects of quality of care for TB patients in all HFs were promising. But structural & process aspects of quality of care was compromised which necessitate different corrective actions to be taken by different stakeholders to enhance quality of care for TB patients in public HFs studied. Moreover based on the study findings, continuous supply of drugs, laboratory equipment and reagents, availing current guideline/s in HFs, providing up-to-date training for HWs on TB and proper documentation are important to improve quality of care provided for TB patients.

RESUMO

BACKGROUND: Intestinal schistosomiasis is a disease caused by infection with one of the blood flukes called Schistosoma mansoni. The distribution of Schistosoma mansoni infection is high in Sub-Saharan Africa due to water source, sanitation and hygiene problems. This study aimed to determine the effect of water source, sanitation and hygiene on the prevalence of schistosomiasis among school-age children in Northwest Ethiopia. METHODS: A cross-sectional study was conducted from Apr 2016 to Aug 2016. Children were selected by systematic random sampling and Formol Ether Concentration Technique (FECT) was used to identify Schistosoma mansoni infection. Statistical analysis was done using descriptive statistics and strength of association of schistosomiasis with determinant factors was calculated by bivariate analysis. RESULTS: Among 333 children, 7% were infected with Schistosoma mansoni. Using surface water for drinking, poor hand wash habit and latrine utilization were significantly associated (P<0.05) with Schistosoma mansoni infection. CONCLUSION: Absence of safe water for bathing, washing and swimming, poor sanitation and hygiene practices were major risk factors for schistosomiasis. Therefore, health education should be given on the transmission of S. mansoni infection, pure water, sanitation and hygiene in S. mansoni endemic areas.

RESUMO

The aetiology of diarrhoea with Cryptosporidium species and pathogenic bacteria has not been identified in the Ethiopian primary healthcare system. Thus, antibiotic consumption for unconfirmed pathogenic diarrhoea is not infrequent. A total of 344 children aged <5 years with diarrhoea were included in the present study to determine protozoal or bacterial aetiology and antibiotic use. Overall, 47.1% of children with diarrhoea had either protozoan or bacterial pathogens. The prevalence of Cryptosporidium species was 12.8% while bacterial pathogens were 13.1%. Based on direct microscopic stool examination, 77.6% (267/344) of children with diarrhoea were treated with antimicrobials. Of these, 16.7%-51.4% of prescribed antimicrobials were appropriate. None of the children with Cryptosporidium diarrhoea were treated with the appropriate antimicrobial. Enteric bacterial pathogens showed a resistance of 51.6% to cotrimoxazole. Empirical treatments are not appropriate for the majority of child cases of diarrhoea.

RESUMO

BACKGROUND: Multi-drug resistant (MDR) Acinetobacter baumannii and Pseudomonas aeruginosa are major causes of nosocomial infections globally. They are the current World Health Organization critical priority pathogens for resistance, Antimicrobial resistance (AMR) surveillance and discovery of new antibiotics. However, there is paucity of data on nosocomial infections (NIs) caused by such superbugs in Ethiopia. Therefore, this study determined the magnitude and profile of nosocomial MDR A. baumannii and P. aeruginosa infections among patients hospitalized at Felegehiwot referral hospital, Northwest Ethiopia. METHODS: A cross-sectional study was conducted at Felegehiwot referral hospital from April 1 to July 31, 2018. A total of 238 patients with blood stream, urinary tract and surgical site NIs were enrolled conveniently. Either blood, urine and wound swab specimens were collected and processed using standard bacteriological procedures. A. baumannii and P. aeruginosa isolates were identified using standard bacteriological techniques and confirmed by automated Vitek2 Compact. Antimicrobial susceptibility testing on isolates was performed using the disk diffusion technique. The results were interpreted as per the standard zone sizes of Clinical and Laboratory Standards Institute.Chi-square test was done to determine associations among variables. P value < 0.05 was considered statistical significant. RESULTS: The median age of participants was 29 years. Overall,20(8.4%) of patients had nosocomial MDR A. baumannii and P. aeruginosa infections. The proportion of nosocomial MDR blood stream, urinary tract and surgical site infections were 13(8.9%), 5(8.3%) and 2 (6.3%), respectively. Patients with NI had lower mean age (24.9 years) (P = 0.035). All isolates of NIs were from patients with intravenous catheterization. The frequency of NI was 9(3.8%) for MDR A. baumannii and 11(4.6%) for MDR P.aeruginosa. A. baumannii and P. aeruginosa isolates were 100% MDR. All isolates of A. baumannii and P. aeruginosa were 100% resistant to ampicillin and piperacillin.A. baumannii isolates were 33.3 and 44.5% resistance against meropenem and ciprofloxacin, respectively while P.aeruginosa isolates revealed 36.4 and 45.5% resistance against ciprofloxacin and meropenem, respectively. CONCLUSIONS: Health care associated infections of MDR A.baumannii and P. aeruginosa are critical problems in the study area. Therefore, urgent focused interventions required to contain the spreading of MDR NIs. Treatment of NIs for patients on health care should be guided by antimicrobial susceptibility testing.

RESUMO

BACKGROUND: Anaemia is a low blood haemoglobin concentration and has been shown to be a public health problem affecting both developing and developed countries. Pregnant women are the most vulnerable groups to anaemia due to several factors, including parasitic infection and feeding habits during their pregnancy. The aim of this study was to assess the prevalence and determinant factors of anemia in pregnant women in Northwest Ethiopia. METHODS: A cross-sectional study was conducted among pregnant women from February, 2017 to June, 2017. The data on determinant factors were collected using a structured questionnaire. The hemoglobin level and intestinal parasites were determined using Hemocue HB 201 and formol ether concentration techniques, respectively. Data was entered and analyzed using SPSS version 23 statistical software. Bivariate and multivariate regressions were computed and odds ratio was determined at 95% confidence interval. RESULTS: The study consists of 743 participants with a median age of 25 years were included. The prevalence of anemia among pregnant women was 79 (10.6%). The prevalence of mild, moderate and severe anaemia were 78 (99.8%), 1 (0.1%) and 1 (0.1%), respectively. Pregnant women of rural dwellers (AOR = 3.72, CI =1.51-9.18), farmer in occupation (AOR = 3.51, CI = 1.75-7.01), and not educated (AOR = 2.25, CI = 1.13-4.48) were significantly associated with increased risk of anemia. CONCLUSION: Anaemia is still a problem amongst pregnant women in the study area though much has been done to increase the hemoglobin level during pregnancy. Health education should be given on factors that aggravate anaemia during pregnancy.

RESUMO

BACKGROUND: Hookworm infection is a common parasitic infection in sub-Saharan Africa. The prevalence of hookworm infection is influenced by different determinant factors. This study aimed to determine the prevalence of hookworm infection and determinant factors among school age children in North West Ethiopia. METHODS: A cross-sectional study was conducted from April 2016 to August 2016. Children were selected by systematic random sampling and Formoleether concentration technique was used to identify hookworm infection. We conducted descriptive and logistic regression analysis for categorical variables. The adjusted odds ratio was calculated at 95% confidence interval. RESULTS: Among 333 children, 49 (14.7%) were infected with hookworm parasites. Eating raw vegetables, not wearing shoes, absence of regular wearing of shoes and hand washing habit, absence of proper utilization of latrines, absence of deworming were significantly associated (p<0.05) with hookworm infection. CONCLUSION: The prevalence of hookworm infection was high among school age children. Walking with bare foot, hand washing habit, and absence of proper latrine utilization are the major determinant factors for the high prevalence of hookworm infection. Therefore, community mobilization and health education should be done to decrease hookworm infection among school age children in Jawe district.

RESUMO

BACKGROUND: Clinical Rabies is a widely distributed almost 100% fatal viral zoonotic disease. Most human rabies cases occur in developing countries, especially in Asia and Africa. It can be prevented by immunization, post exposure prophylaxis. Ethiopia is assumed to be among African countries with high incidence of human rabies exposure cases. However, there is limited documented data on the incidence of human rabies exposure in the study area in particular and in Ethiopia in general. Thus, this study aimed to determine the Incidence of Human Rabies Virus exposure in Northwestern Amhara, Ethiopia. METHODS: Retrospective cross-sectional study was conducted during August and September, 2017. The study was conducted at Addis Alem Hospital, a district level hospital in Bahir Dar. Data on human rabies exposure cases registered from September 1, 2015 to August 31, 2017 were collected from anti-rabies post exposure prophylaxis registration log book. Data was collected using a structured data collection questionnaire developed for this purpose. Descriptive statistics was used to describe relevant variables. THE RESULTS: A total of 924 human rabies exposure cases was recorded. The overall human rabies incidence per 100, 000 population was 6.5 in 2015 and 7.5 in 2016. Males (55.2%, 510/924) and children of age less than fifteen (46.3%, 428/924) were most affected groups. The majority of human rabies exposure cases (71.9%, 664/924) were from rural settings. Dogs were the principal sources of exposure (96.3%) followed by cat (1.5%) and donkey (1.3%). High incidence rate of rabies exposure was reported during spring (360, 39%) and summer (244, 26.4%) seasons. There was significant difference between rural and urban exposure cases (p = 0.001) in respect to the time of arrival to the hospital. CONCLUSION: Taking these into account, a significant proportion of the population was exposed to rabies virus during the study years. There was high human rabies exposure rate in children and in the rural community. This shows the need for organizing preventive and control strategies and to build community awareness.

RESUMO

BACKGROUND: According to the Ethiopian national malaria indicator survey of 2015, the highest burden of Plasmodia infection resided among the school-age children. Even though several studies revealed various determinant factors of childhood malaria, consistent findings are not reported across the nation and elsewhere. This in turn creates obstacles in implementing exactprevention and control measures in the study area in particular and the country at large. OBJECTIVES: The aim of this study is to determine the incidence of Plasmodium and determinant factors among febrile children in Northwest Ethiopia. METHODS: This cross-sectional study was conducted from April-August 2016. Blood samples were collected from febrile children selected by systematic random sampling. Thin and thick blood films were prepared and stained with Giemsa. Statistical analysis was done via SPSS version 20 statistical software and data were summarized with percentages and frequencies. The bi-variate and multi-variate logistic regressions were used to measure strength of association between Plasmodium infection and determinant factors, and to rule out confounders, respectively. RESULT: Among a total of 333 febrile children, 146 (43.8%) were positive for the Plasmodia. The prevalence of plasmodium infection was 47%, 50%, and 40%, among the age groups of 6-8, 9-10 and 11-14 years, respectively. Prevalence of plasmodium among male and female children was 44.2% and 43.5%, respectively. Shorter distance from stagnant water (AOR (adjusted odds ratio) =43, 95% CI (confidence interval):2.8-680.7; P < 0.01), family size (AOR =14.7, 95% CI:(1.4-151.2; P = 0.02), outdoor sleeping (AOR =36.6, 95% CI:2.4-554.2; P < 0.01, irregular bed net use (AOR =21.1, 95% CI:2.9-154.7; P < 0.01), and late bed time (AOR =31.9, 95% CI:2.8-371.3; P < 0.01) showed statistically significant association with plasmodium infection. CONCLUSION: The incidence of Plasmodium infection is high among febrile children in the study area. Shorter distance from stagnant water, larger family size, outdoor sleeping, irregular bed net use, and late night sleeping are the major determinant factors for the high incidence of malaria. Therefore, community mobilization and health education should focus on the specific determinant factors of plasmodium infection to alleviate incidence of malaria among the school children.

RESUMO

Plasmodium coinfection with hookworm and/or Schistosoma mansoni has detrimental effects on human's hemoglobin level. This study aimed to determine the effects of plasmodium, hookworm, and S. mansoni infections on hemoglobin level among febrile school age children in Northwest Ethiopia. A cross-sectional study was conducted from April 2016 to August 2016. Plasmodium and helminths infections were detected using Giemsa stain and formol-ether concentration techniques, respectively. Hemoglobin level was determined using Hemocue method. Among 333 children, 143 (42.9%), 49 (14.75%), and 22 (6.6%) had Plasmodium, hookworm, and Schistosoma mansoni infections, respectively. The prevalence of Plasmodium-hookworm and Plasmodium-Schistosoma mansoni coinfections was 18 (12.6%) and 4 (2.8%) in children, respectively. The overall prevalence of anaemia in children was 41.4%. Effect of Plasmodium, hookworm, and Schistosoma mansoni on hemoglobin level was high. Therefore, febrile children should be screened for Plasmodium, hookworm, Schistosoma mansoni, and anaemia simultaneously in malaria endemic areas.
