Anthropometric Improvement among HIV Infected Pre-School Children Following Initiation of First Line Anti-Retroviral Therapy: Implications for Follow Up.

BACKGROUND: Antiretroviral therapy (ART) is a lifesaving intervention for HIV infected children. There is a scarcity of data on immunological recovery and its relation with growth indicators among HIV infected young children. The current study aims to assess the pattern of anthropometric Z-score improvement following initiation of first-line ART among under-five children and the relationship between anthropometric Z-score improvement and immunologic recovery. METHODS: We included under-five children who were on first-line ART at five major hospitals in Addis Ababa, Ethiopia. We measured anthropometry and collected clinical and laboratory data at follow up, and we retrieved clinical and anthropometric data at ART initiation from records. Z-scores for each of the anthropometric indices were calculated based on WHO growth standards using ENA for SMART 2011 software. Linear regression was used to assess the relationship between time on ART and anthropometric Z-score improvement; and the relationship between anthropometric Z-score improvement and immunologic recovery. Multiple linear regression was used to assess the independent predictors of anthropometric Z-score change. RESULTS: The median age of the participants was 4.1 (Interquartile range (IQR): 3.3-4.9) years. More than half (52.48%) were female. The median duration of follow up was 1.69 (IQR: 1.08-2.63) years. There was a significant improvement in all anthropometric indices at any follow up after initiation of first-line ART (underweight; 39.5% vs16.5%, stunting; 71.3% vs 62.9% and wasting; 16.3% vs 1.0%; p-value< 0.0001). There was an inverse relationship between improvement in weight for age Z-score (WAZ) and duration of ART (R2 = 0.04; F (1, 158); p = 0.013). Height for age Z-score (HAZ) both at the time of ART initiation and follow up has a positive linear relationship with CD4 percentage at follow up (Coef. = 1.92; R2 = 0.05; p-value = 0.002). Duration on ART (Std. Err. = 0.206, t = -1.99, p-value = 0.049) and level of maternal education (Std. Err. = 0.290, t = 2.64, p-value = 0.009) were the only independent predictors of the change in WAZ and change in HAZ at any follow up visit respectively. CONCLUSION: There was a significant improvement in all anthropometric indices at any follow-up after initiation of first-line ART among under-five children. HAZ was linearly related with immunologic recovery following ART initiation. The findings indicate that anthropometric indices could be taken as proxy indicators of immunologic recovery for under-five children.

High Gastrointestinal Colonization Rate with Extended-Spectrum ß-Lactamase-Producing Enterobacteriaceae in Hospitalized Patients: Emergence of Carbapenemase-Producing K. pneumoniae in Ethiopia.

We investigated the gastrointestinal colonization rate and antibiotic resistance patterns of Extended-Spectrum Beta-Lactamase (ESBL)- producing Escherichia coli and Klebsiella pneumoniae in hospitalized patients admitted at Ethiopia's largest tertiary hospital. Fecal samples/swabs from 267 patients were cultured on chrome agar. ESBL. Bacterial species identification, verification of ESBL production and antibiotic susceptibility testing were done using Vitek 2 system (bioMérieux, France). Phenotype characterization of ESBL-E.coli and ESBL- K.pneumoniae was done using Neo-Sensitabs™. ESBL positivity rate was much higher in K. pneumoniae (76%) than E. coli (45%). The overall gastrointestinal colonization rate of ESBL producing Enterobacteriaceae (ESBL-E) in hospitalized patients was 52% (95%CI; 46%-58%) of which, ESBL-E. coli and K.pneumoniae accounted for 68% and 32% respectively. Fecal ESBL-E carriage rate in neonates, children and adults was 74%, 59% and 46% respectively. Gastrointestinal colonization rate of ESBL-E.coli in neonates, children and adults was 11%, 42% and 42% respectively. Of all E. coli strains isolated from adults, children and neonates, 44%, 49% and 22% were ESBL positive (p = 0.28). The prevalence of ESBL-K.pneumoniae carriage in neonates, children and adults was 68%, 22% and 7% respectively. All K. pneumoniae isolated from neonates (100%) and 88% of K. pneumoniae isolated from children were ESBL positive, but only 50% of K.pneumoniae isolated from adults were ESBL positive (p = 0.001). Thirteen patients (5%) were carriers of both ESBL-E.coli and ESBL-KP. The overall carrier rate of ESBL producing isolates resistant to carbapenem was 2% (5/267), all detected in children; three with E.coli HL cephalosporinase (AmpC), resistant to ertapenem and two with K. pneumoniae Carbapenemase (KPC) resistant to meropenem, ertapenem and impenem. We report a high gastrointestinal colonization rate with ESBL-E and the emergence of carbapenems-resistant K. pneumoniae in Ethiopia. Urgent implementation of infection control measures, and surveillance are urgently needed to limit the spread within healthcare facilities and further to the community.

PATTERN AND OUTCOME OF RENAL DISEASES IN HOSPITALIZED CHILDREN IN TIKUR ANBESSA SPECIALIZED TEACHING HOSPITAL, ADDIS ABABA, ETHIOPIA.

Background: Renal diseases are major causes of morbidity and mortality in pediatric practice. Pediatric patients with renal disease, especially younger ones may present with nonspecific signs and symptoms unrelated to the urinary tract. Unexplained fever or failure to thrive may be the only manifestation. Most children with renal diseases in our hospital arrive very late either because of inadequate health awareness among the parents or failure of recognizing the symptoms of renal diseases at a lower health care level. This review will highlight the symptoms of renal diseases at presentation and outcomes of treatment in children in a major referral hospital. Methods: A cross-sectional retrospective chart review was done over a period of 3 years (June, 2012 to May, 2015) in 381 admitted children (Birth-17 years) at Tikur Anbessa Specialized Teaching Hospital in Addis Ababa, Ethiopia. Results: Out of 14521 pediatric ward admissions in the study period, kidney diseases accounted for 473 admissions in 381 children, accounting for 3.3% of all admissions. The three most common renal diseases observed were congenital anomalies of the kidney and urinary tract (CAKUT) seen in 127 children (26.8%), followed by nephrotic syndrome in 80 children 16.9% and acute glomerulonephritis in 58 children (12.2%). Other renal diseases observed were urinary tract infection 8.0%, urolithiasis 6.7%, Wilm's tumor 6.3%, acute kidney injury 4.2% and chronic kidney disease 4.0%. Other less frequently detected diseases were bladder exstrophy, lupus nephritis, Henock shonlein Purpura nephritis and prune-belly syndrome. Out of 381 children 207 (54.3%) recovered normal renal function, 20(5.2%) remained with proteinuria, 13(3.4%) progressed to chronic kidney disease and 11(2.9%) died. Sixty one nephrotic children (76.3%) achieved remission but 17 children (21.3%) remained with proteinuria; one steroid resistant child died of end stage renal disease. Ten children (2.6%) with different renal diseases were lost to follow-up and 5 (1.3%) discharged against medical advice. Conclusions: This data reflects that many of the renal diseases are preventable or potentially curable. Therefore, improvement of pediatric renal services and training of health workers would help in early detection and treatment of these conditions leading to reduction in their morbidity and mortality.

Reference Ranges for Head Circumference in Ethiopian Children 0-2 Years of Age.

BACKGROUND: Head circumference (HC) charts are important for early detection of hydrocephalus during childhood. In low-income countries where population-based HC charts are rarely available, hydrocephalus occurs more commonly than in developed countries, and is usually not diagnosed early enough to prevent severe brain damage. This applies to Ethiopia as well. The World Health Organization (WHO) has provided standard HC charts advocated for global use, but recent studies cast doubts whether these charts are equally applicable in various populations. The aim of the study was therefore to establish reference ranges for early childhood HC in Ethiopia. METHODS: In this prospective, observational cross-sectional study, measurements of HC were collected from healthy children of different ethnicities between birth and 24 months, in health centers situated in 5 Ethiopian cities. Reference ranges for HC were estimated using the LMS method and compared with those recommended by WHO. RESULTS: A total of 4019 children were included. Overall, 6.7% of boys and 7.1% of girls were above the +2 standard deviation (SD) of the WHO reference ranges, whereas the corresponding figures below -2 SD were 2.8% and 2.1%. Similarly, the +2 SD lines of the Ethiopian reference curves were considerably higher than those of the WHO growth standards, whereas the median and -2 SD lines were more comparable. CONCLUSIONS: Ethiopian HC reference ranges for children from birth to 24 months of age were found to differ significantly from those established by WHO and should correspondingly be considered as the first choice for screening for hydrocephalus in that population.

Adrenocortical carcinoma in a 3% years old girl with hetro-sexual precocity.

Adrenocortical carcinoma is a rare neoplasm in children. Hetro-sexual precocious puberty could be the initial presentation of a rare adrenocortical neoplasm in the pediatric age group. Features of hetro-sexual precocious puberty in a girl should alert the possibility of such a rare disease. We report a rare case of adrenocortical carcinoma in a three years and six months old girl who presented with hetro-sexual precocious puberty of two years duration. Left adrenalectomy was done and histopathology revealed adrenocortical carcinoma.

Febrile illnesses of different etiology among outpatients in four health centers in Northwestern Ethiopia.

Fever of different etiology is common in tropical and subtropical countries of the world. Etiological agents of febrile illnesses were assessed in 653 acute febrile patients aged 3 to 17 years who attended the outpatient departments of Dembecha Health Center, Jiga Health Center, Quarit Health Center, and Finoteselam Hospital in western Gojjam zone, northwestern Ethiopia. Malaria was the most prevalent illness, infecting 62% of all cases. Its prevalence varied significantly from 52% (Dembecha) to 72.7% (Quarit) (chi(2)=15.02, P=0.000). Plasmodium falciparum was the first cause of malaria (47.3%) followed by P. vivax (23%). Mixed infection of both P. falciparum and P. vivax was found in 7.2% of the cases. The other febrile infections were pneumonia (7%), typhoid (5.8%), typhus (5.1%), and brucellosis (2.6%). The availability of diagnostic facilities and the awareness of the community regarding the prevalence of non-malaria febrile illnesses are very low, and these illnesses are diagnosed clinically. As these illnesses are nonspecific, especially during the early stages of onset, misdiagnosis and mistreatment can occur. Therefore, it is recommended that the necessary diagnostic materials and awareness should be in place for prompt treatment of febrile cases in these districts.

Clinical profile of acute renal failure in children admitted to the department of pediatrics, Tikur Anbessa Hospital.

Case records of 30 pediatric patients with the diagnosis of acute renal failure (ARF) admitted to Tikur Anbessa Hospital in Addis Ababa between October 1997 and October 2001 were analyzed There were 15 females and 15 males. Three patients had glomerulonephritis, in two patients the cause of acute renal failure was not known, one child had obstructive uropathy. Twenty-three patients had post-diarrheal hemolytic uremic syndrome. The age ranges of post-diarrheal hemolytic uremic syndrome cases were between 0.6 years and 7 years with a median age of 2.2 years. Fourteen patients died of acute renal failure among this hemolytic urmic syndrome contributed to the death of 9 patients. The commonest clinical presentation was severe oligo-anuria in (25 patients), edema in (22 patients), and bloody diarrhea in (21 patients). From stool cultures of 16 patients with hemolytic uremic syndrome, there were five isolates of Shigella species, two isolates of E. coli, and two isolates of Salmonella species. Five patients had non-oliguric acute renal failure. Hemolytic uremic syndrome is the leading cause of acute renal failure in infants and young children in our series. Vigorous resuscitation and early dialysis will reduce mortality rate.
