Nutritional assessment and associated factors in children with congenital heart disease-Ethiopia.

INTRODUCTION: Worldwide, congenital heart disease is the principal heart disease in children and constitutes one of the major causes of infant mortality, particularly in developing countries. Infants and children with congenital heart disease exhibit a range of delays in weight gain and growth. In some instances, the delay can be relatively mild, whereas in other cases, cause the failure to thrive. OBJECTIVES: To determine the nutritional status and associated factors of pediatric patients with congenital heart disease. MATERIAL AND METHOD: A cross sectional analytical study conducted over a period of 6 months (Feb to Jul 2020). A total of 228 subjects with congenital heart disease who visited the cardiac center during the study period where included until the calculated sample size attained. Data is collected from patient's card and their care giver. Data was then analyzed using Statistical Package for Social Sciences (SPSS) for windows version 25.0. Odds Ratio with 95% Confidence Interval (CI) was used to determine the effect of the independent variables on the outcome variable and P-value less than 0.05 was considered statistically significant. RESULTS: A total of 228 children ranging from 3month to 17yrs of age with mean age of 4.7 years (SD = 3.8 years) were included in the study. Most of the subjects had acyanotic heart disease accounting for 87.7%. The overall prevalence of wasting, underweight and stunting were 41.3%, 49.1% and 43% respectively. Children with congenital heart disease and having pulmonary hypertension, were found more likely to develop wasting compared to those without pulmonary hypertension with an odds of 1.9 (95% CI: 1.0-3.4) and also have greater chance of stunting with an odds of 1.9 (95% CI: 1.0-3.4). Children 5 to 10 years of age were 2.3 times more likely to be underweight. CONCLUSION: Malnutrition is a major problem in pediatric patients with congenital heart disease. Pulmonary hypertension and older age are associated with increased risk of undernutrition.

Secondary prevention of rheumatic heart disease in Ethiopia: a multicenter study.

BACKGROUND: Ethiopia has a high acute rheumatic fever (ARF) and rheumatic heart disease (RHD) prevalence, and to our knowledge, there are no data on the status of secondary prevention in children with RHD. This study describes the status of secondary RHD prevention. METHODS: A multicenter, prospective study was performed on children aged 5-17 years with RHD in Ethiopia. Good adherence was defined as at least 80% completion of benzathine penicillin (BPG) or oral Amoxicillin within the previous year. The primary outcome measure was adherence to prophylaxis, expressed as a proportion. Socio-demographics, severity of RHD, and ARF recurrence were evaluated. RESULTS: A total of 337 children with a mean age of 12.9 ± 2.6 years were included. The majority (73%) had severe aortic/mitral disease. Participants were on BPG (80%) or Amoxicillin (20%) prophylaxis. Female sex (P = 0.04) use of BPG (0.03) and shorter mean duration of prophylaxis in months (48.5 ± 31.5 vs. 60.7 ± 33, respectively, P < 0.008) predicted good adherence. Running out of medications (35%), interrupted follow-up (27%), and the COVID-19 pandemic (26%) were the most common reasons for missing prophylaxis. Recurrence of ARF was higher in participants on Amoxicillin compared with BPG (40% vs. 16%, P < 0.001) and in those with poor adherence compared with good adherence (36.8% vs. 17.9%, respectively, P = 0.005). Type and duration of prophylaxis (OR 0.5, CI = 0.24, 0.9, P = 0.02; OR = 1.1, CI = 1.1, 1.2, P = 0.04, respectively), and sex (OR = 1.9, CI = 1.1, 3.4, P = 0.03) were independent predictors of poor adherence. CONCLUSION: Poor adherence is prevalent in Ethiopian children living with RHD. Amoxicillin is a suboptimal option for prophylaxis as its use is associated with lower adherence and a higher rate of ARF recurrence.

Contemporary outcomes of aortic and mitral valve surgery for rheumatic heart disease in sub-Saharan Africa.

OBJECTIVES: Rheumatic heart disease is endemic in sub-Saharan Africa. There is a paucity of data on the outcomes of valvular surgery for rheumatic heart disease in the developing world. The objective of this study was to evaluate the outcomes of aortic and mitral valve surgery for rheumatic heart disease in Ethiopia. METHODS: Between 2009 and 2017, 240 consecutive patients with rheumatic heart disease underwent aortic and/or mitral surgery at the Cardiac Center of Ethiopia in Addis Ababa. These surgeries were performed in the context of 22 international humanitarian missions. Median follow-up was 2.3 (interquartile range, 0.5-4.0) years and 96% complete. Outcomes were compared between patients who underwent mechanical valve implantation (n = 90, 38%), bioprosthetic valve implantation (n = 58, 24%), and valve repair (n = 92, 38%). RESULTS: Mean age of patients was 19 ± 8 years, and 136 patients (57%) were female. Operative mortality occurred in 5 patients (2.1%) and was not significantly different between the groups. Eleven additional patients (5%) died at follow-up, and 55 patients (23%) had at least 1 major adverse valve-related event. Propensity score-adjusted Cox regression analysis demonstrated higher rates of death in the bioprosthetic group compared with the mechanical group (hazard ratio, 8.82; 95% confidence interval, 1.64-47.39; P = .011). Survival was not significantly different between the repair and mechanical groups (hazard ratio, 1.09; 95% confidence interval, 0.17-7.16; P = .93). Likewise, rates of major adverse valve-related event were higher in the bioprosthetic group compared with the mechanical group (hazard ratio, 2.71; 995% confidence interval, 1.13-6.49; P = .025), but not significantly different between the repair and mechanical groups (hazard ratio, 1.98; 95% confidence interval, 0.89-4.39; P = .092). CONCLUSIONS: Left-sided valve surgery for rheumatic heart disease in sub-Saharan Africa is associated with acceptable perioperative outcomes, but a high incidence of major adverse valve-related event at follow-up. The use of bioprosthetic valves is associated with poor outcomes in this patient population.

Antimicrobial suceptibility of V. cholerae in north west, Ethiopia.

OBJECTIVES: Various Vibrio cholerae serogroups cause cholera, which occurs as major epidemic disease in most developing countries. This study was aimed at determining the antimicrobial susceptibility patterns of V. cholerae and its serotypes from cholera cases. METHODS: The study was undertaken during cholera epidemics in North West Ethiopia from August 2006 to September 2008. Diarrheic stool samples were processed per the standard microbiology procedures at Bahir Dar Regional Health Research Laboratory. Antimicrobial susceptibility tests were performed using disc diffusion technique per Kirby-Bauer method. RESULTS: Eighty one V. cholerae 01 serotype Inaba were isolated from stools of cholera cases. Antibiograms of V. cholerae 01 Inaba showed that 71.6% of isolates were resistant against two, 18.4% to three and 5% to four antibiotics. All V. cholerae Inaba isolates were resistant to co-trimoxazol 81 (100%). High levels of resistance were also shown to chloramphenicol 76 (94%) and ampicillin 72 (89%) with least resistance to erythromycin 12 (15%), tetracycline 5 (6.2) and ciprofloxacilin 1 (1.2%). However, all isolates remain susceptible to doxycycline 81 (100%). CONCLUSION: In the study area, doxycycline or ciprofloxacilin could be used for treatment of adult cholera cases whereas erythromycin is alternative for young children. Antimicrobial susceptibility tests are strongly recommended for V. cholerae strains in treatment intervention during epidemics.

Evaluation of Determine HIV-1/2 rapid diagnostic test by 4th generation ELISA using blood donors' serum at Felege Hiwot Referral Hospital, northwest Ethiopia.

OBJECTIVE: The study aims to evaluate the HIV-1/2 rapid diagnostic test kit is routinely used to screen HIV infection for safe blood transfusion and VCT services in many parts of Ethiopia. METHODS: A total of 324 sera were collected from consecutive blood donors from February to May 2006. All samples were screened for HIV infection using Determine HIV-1/2 (Abbott Japan) at hospital blood bank laboratory. Blindly, all serums were retested at Regional Health Research Laboratory using 4th generation ELISA (Vironostika HIV Uni-Form II AG/Ab) and Determine HIV-1/2 (Abbott lab). Discordant samples were repeatedly retested using the same ELISA and Determine HIV-1/2 to avoid technical errors. Finally, discordant results were resolved using Western Blot at the National HIV/AIDS Laboratory. RESULTS: Determine HIV-1/2 and ELISA showed 94.4% concordance in HIV antibody testing with fair Cohen's Kappa statistic value (0.68) among blood donors. The sensitivity, specificity, positive and negative predictive values of Determine HIV-1/2 were 60.5%, 98.9%, 88.5% and 94.9% respectively. CONCLUSION: As a rapid HIV screening test for blood donors, Determine HIV-1/2 showed poor sensitivity. Further evaluation at multiple centres is recommended to test its validity as a routine HIV screening test in blood donors. Use of a combination of rapid assays is also recommended for screening of HIV infection among the donor population.

Conjoined twins sharing major organs and with discordant congenital anomaly.

Thoraco-omphalopagus conjoined twins born to a 25-year-old para one Ethiopian lady are presented. Prenatal diagnosis was not made until elective cesarean section delivery was done for severe preeclampsia and twin pregnancy with breech presentation. Detailed autopsy results and relevant literature reviews are described. To the best of our knowledge, these are the second-documented cases of conjoined twins in this country.
