BackgroundThe emergence of resistance to first line antiretroviral therapy (ART) regimen leads to the need for more expensive and less tolerable second line drugs. Hence, it is essential to identify and address factors associated with an increased probability of first line ART regimen failure. The objective of this article is to report on the predictors of first line ART regimen failure, the detection rate of ART regime failure, and the delay in switching to second line ART drugs.MethodsA retrospective cohort study was conducted from 2005 to 2011. All HIV infected children under the age of 15 who took first line ART for at least six months at the four major hospitals of Addis Ababa, Ethiopia were included. Data were collected, entered and analyzed using Epi info/ENA version 3.5.1 and SPSS version 16. The Cox proportional-hazard model was used to assess the predictors of first line ART failure.ResultsData of 1186 children were analyzed. Five hundred seventy seven (48.8%) were males with a mean age of 6.22 (SD = 3.10) years. Of the 167(14.1%) children who had treatment failure, 70 (5.9%) had only clinical failure, 79 (6.7%) had only immunologic failure, and 18 (1.5%) had both clinical and immunologic failure. Patients who had height for age in the third percentile or less at initiation of ART were found to have higher probability of ART treatment failure [Adjusted Hazard Ratio (AHR), 3.25 95% CI, 1.00-10.58]. Patients who were less than three years old [AHR, 1.85 95% CI, 1.24-2.76], chronic diarrhea after initiation of antiretroviral treatment [AHR, 3.44 95% CI, 1.37-8.62], ART drug substitution [AHR, 1.70 95% CI, 1.05-2.73] and base line CD4 count below 50 cells/mm3 [AHR, 2.30 95% CI, 1.28-4.14] were also found to be at higher risk of treatment failure. Of all the 167 first line ART failure cases, only 24 (14.4%) were switched to second line ART with a mean delay of 24 (SD = 11.67) months. The remaining 143 (85.6%) cases were diagnosed to have treatment failure retrospectively by the authors based on their records. Hence, they were not detected and these patients were not offered second line ARTs.ConclusionsHaving chronic malnutrition, low CD4 at base line, chronic diarrhea after initiation of first line ART, substitution of ART drugs and age less than 3 years old were found to be independent predictors of first line ART failure in children. Most of the first line ART failure cases were not detected early and those that were detected were not switched to second line drugs in a timely fashion. Children with the above risk factors should be closely monitored for a timely switch to second line highly active anti-retroviral therapy.

BackgroundMicroscopic diagnosis of Giemsa stained thick and thin blood films by skilled microscopists has remained the standard laboratory method for the diagnosis of malaria. However, detection and identification of malaria parasites require well trained laboratory personnel.The objective of the study was to evaluate the performance of laboratory technologists and technicians in detecting and identifying malaria parasites in Hawassa town, Southern Ethiopia.MethodsA cross-sectional study design was employed among a total of 80 laboratory professionals working in public and private health facilities. A standardized pre-validated slide panel and questionnaires were distributed to laboratory professionals working at eleven health facilities in Hawassa town, Southern Ethiopia. The panels included ten slides for diagnosis, [slide1:P.falciparum, 104/μl; slide 2:P.falciparum, 53404/μl; slide 3 and 4: mixed infection (both P. falciparum and P. vivax); slide 5:P.vivax, 23503/μl; slide 6:P.vivax, 400/μl; and slides 7, 8, 9 and 10: negative slides]. Participants were asked to return the responses which were compared with expert microscopist. Agreement in detecting and identifying malaria parasites between participants and expert microscopists was estimated using the Kappa score.ResultsThe mean age of the participants was 27 (SD = 4.1) years. More than half of the participants (56.9%) were female. Fourteen (19.4%) of the participants correctly reported all the ten distributed slides, whereas 58(80.6%) missed at least one slide. Overall, the sensitivity and specificity of participants in detection of malaria parasites were 82% and 96.5% respectively. The overall agreement between participants and reference readers on detection of malaria parasite was 88% (Kappa = 0.76) while on identification of malaria species was 74.3% (kappa = 0.63). Lower agreement on detection and identification of slides with low parasitic density and mixed infection were observed. Agreement was relatively lower for government health centers (69%; kappa = 0.56). None of the participants reported parasitic load per micro liter method.ConclusionAgreement of the participants with expert microscopist in the detection of malaria parasites was better than agreement in the identification of different species of malaria. Poor agreement was reported in detection of parasites at a low density and mixed infections.

BACKGROUND:There is a lack of evidence on description of burden and cases of childhood poisoning in developing countries. This study aimed to assess the characteristics of children with acute poisoning, and factors for time of presentation to health facility and nature of poisoning. METHODS:A cross-sectional study was conducted at three major pediatric referral hospitals in Addis Ababa, Ethiopia. Description of demographics of children with acute poisoning and factors associated with time to presentation and nature of poisoning were analyzed. Data were entered to Epi info 3.5.3 and analyzed with SPSS version 20. RESULTS:Over three years, we retrieved records of a total of 128 children admitted for acute poisoning. The mean age of victims was 5.46 (SD, standard deviation=4.48) years. The majority (29.7%) were poisoned by prescribed drugs. Most poisoning incidents (73.5%) were unintentional in nature. The median time to health facility visit was 15.5 hours. Age less than 2 years was related to earlier presentation to health facility (P=0.010, OR=0.28, 95%CI=0.10-0.74). Children with age more than 5 years was more likely to have intentional poisoning (χ 2 =25.06, P<0.0001). None of the victims was provided psychosocial evaluation and counseling.CONCLUSION: Most poisoning incidents are unintentional. Prescribed drugs are the commonest causes. Psychosocial counseling and care for the affected children is lacking. Family and community education should be given on prevention of poisoning. We recommend that caregivers take the required action in keeping prescribed drugs at home. Psychosocial support should be part of care and treatment of children with poisoning.

BackgroundCockroaches have been described as potential vectors for various pathogens for decades; although studies from neonatal intensive care units are scarce. This study assessed the vector potential of cockroaches (identified as Blatella germanica) in a neonatal intensive care unit setup in Tikur Anbessa Hospital, Addis Ababa, Ethiopia.MethodsA total of 400 Blatella germanica roaches were aseptically collected for five consecutive months. Standard laboratory procedures were used to process the samples.ResultsFrom the external and gut homogenates, Klebsiella oxytoca, Klebsiella pneumoniae, Citrobacter spp. Enterobacter cloacae, Citrobacter diversus, Pseudomonas aeruginosa, Providencia rettgeri, Klebsiella ozaenae, Enterobacter aeruginosa, Salmonella C1, Non Group A streptococcus, Staphylococcus aureus, Escherichia coli, Acinetobacter spp. and Shigella flexneri were isolated. Multi-drug resistance was seen in all organisms. Resistance to up to all the 12 antimicrobials tested was observed in different pathogens.ConclusionCockroaches could play a vector role for nosocomial infections in a neonatal intensive care unit and environmental control measures of these vectors is required to reduce the risk of infection. A high level of drug resistance pattern of the isolated pathogens was demonstrated.

BackgroundDiabetic retinopathy is one of the micro vascular complications of diabetes mellitus. To date there are no studies that show the magnitude of diabetic retinopathy in the pediatric population of Ethiopia with only very few in Africa. The purpose of this study was to determine the prevalence of diabetic retinopathy in children and adolescents at a tertiary center in Ethiopia.MethodsThis cross-sectional hospital based descriptive study included children aged between 9 and 17 years attending the endocrine follow-up clinic of Tikur Anbesa Specialized Hospital. A structured questionnaire was used for evaluating sociodemographic data and information pertinent to diabetes. The prevalence of diabetic retinopathy was determined by fundus photography of each eye.ResultsA total of 86 patients were examined with a mean age of 13.7 (SD = 1.8) years. At onset of diabetes, 95.6 % of children presented with diabetic ketoacidosis(DKA); 22 children (25.6 %) had at least two episodes of DKA, and 45 children (52.3 %) had poor glycemic control. Background retinopathy was present in four children (4.7 %) with a mean age of 14.25 (SD = 1.89) years and two of them also had maculopathy.ConclusionAlthough there are some methodological limitations, this study highlights the difficulties of achieving good glycemic control and the early occurrence of diabetic retinopathy in Ethiopian diabetic children.
