Prevalence and factors associated with rotavirus diarrhea among children aged 3-24 months after the introduction of the vaccine at a referral hospital in Uganda: a cross-sectional study.

BACKGROUND: Rotavirus has a significant morbidity and mortality in children under two years. The burden of rotavirus diarrhea 4 years post introduction of rotavirus vaccine in Uganda is not well established. This study aimed to determine the prevalence, severity of dehydration and factors associated with rotavirus diarrhea among children aged 3 to 24 months after the introduction of the vaccine at Fort Portal Regional Referral hospital. METHODS: This was a cross-sectional hospital-based study in which children with acute watery diarrhea were included. A rectal tube was used to collect a stool sample for those unable to provide samples. Stool was tested for rotavirus using rapid immunochromatographic assay. Data was analysed using SPSS version 22 with logistic regression done to determine the factors. RESULTS: Out of 268 children with acute watery diarrhea, 133 (49.6%) were females. Rotavirus test was positive in 42 (15.7%), majority of whom had some dehydration 28(66.7%). The factors that were independently associated with rotavirus diarrhea were; age < 12 months (AOR = 8.87, P = 0.014), male gender (AOR = 0.08, P = 0.001), coming from a home with another person with diarrhea (AOR = 17.82, P = 0.001) or a home where the water source was a well (AOR = 50.17, P = 0.002). CONCLUSION: The prevalence of rotavirus diarrhea was three times less in the post rotavirus vaccination period compared to pre-rota vaccination period. Majority of the participants with rotavirus diarrhea had some dehydration. There is need for provision of safe water sources to all homes. Surveillance to determine the cause of the non rota diarrhea should be done.

Prevalence and Factors Associated with Iron Deficiency Anaemia among Children Aged 6-23 Months in Southwestern Uganda.

Iron deficiency anaemia is still a global public health concern with the highest burden among children 6 to 23 months due to their rapid growth spurt exceeding breastmilk supply. Therefore, nutritional supply is a key source of iron to attain the required nutrients for better growth and development. This was a cross-sectional descriptive study done at Ishaka Adventist Hospital (IAH) and Kampala International University Teaching Hospital (KIUTH) from April to July 2022. Participants were consecutively enrolled in the study. Structured questionnaires, 24-hour dietary recall, and clinical assessment were used to obtain data. Data analysis was done using the statistical package for social scientists (SPSS) V22.0. Bivariable and multivariable analyses were done using logistic regression for associations with significance set at P value < 0.05. A total of 364 participants were enrolled, with the majority being males (198, 54.4%) and born at term (333, 91.5%). The modal age was 12-17 months [163(44.8%)] with a mean age of 14.1 months (SD 5.32). The overall prevalence of IDA was 151/364 (41.5%). The factors associated with IDA included male sex (aOR 1.61), current episode of diarrhoea (aOR 1.71), poor meal frequency (aOR 1.78), no vegetable consumption (aOR 2.47), and consuming fruits once (aOR 1.97) in 7 days preceding the study. The study finds a high prevalence of IDA among infants 6-23 months with at least four in 10 being affected. Screening for IDA should be recommended in male children with current diarrhoea, poor intake of fruits and vegetables, and poor meal frequency. The Mentzer index is an equally good alternative screening test for IDA.

Prevalence and Outpatient Clinical Diagnostic Approaches for Common Acute Respiratory Tract Infections in Children Under Five Years of Age: A Cross-Sectional Study.

Background: Acute respiratory tract infections are among the leading causes of child morbidity and mortality worldwide. Although the diagnosis of acute respiratory tract infections requires simple outpatient medical techniques and care, it is still misdiagnosed among primary care physicians, leading to delayed treatment and increased mortality. This study described the prevalence of common acute respiratory tract infections and simple techniques that effectively detect and diagnose children presenting with acute respiratory symptoms to primary healthcare physicians in remote settings. Patients and Methods: This descriptive cross-sectional study was conducted at the pediatric outpatient clinic of a tertiary hospital in western Uganda in April, May and June 2019. A total of 896 children aged 2-59 months attending the clinic were recruited consecutively into the study and examined for the presence of acute respiratory infection. Participants' sociodemographic and clinical data were collected through history taking and clinical examination using a validated Uganda Ministry of Health Uganda outpatient clinical checklist (FORM 5). The outcome variable was the presence of an acute upper or lower respiratory condition. Data was analyzed using STATA version 13.0 (StataCorp, College Station, USA) and summarized using descriptive statistics. Results: The overall period prevalence of acute respiratory tract infections among children aged 2 to 59 months was 36.9% (36,942 per 100,000 population). Upper respiratory tract infections with a prevalence of 24.8% were more common than lower respiratory tract infections. The most frequent upper respiratory tract infection in this setting was common cold (52%), followed by tonsillopharyngitis (10.7%), while pneumonia (26%) was the most frequent lower respiratory tract infection. Conclusion: Acute respiratory tract infections contribute to the high burden of disease in pediatric outpatient clinics. Simple, affordable, and approved diagnostic clinical techniques that involve physical examination of the upper and lower respiratory systems can precisely diagnose acute respiratory tract infections in resource-limited settings where there is no access to sophisticated diagnostic equipment.

Factors Associated with Acute Kidney Injury among Children with Severe Malaria at Kiryandongo General Hospital, Uganda.

Background: Malaria remains one of the leading health problems of the developing world, and acute kidney injury (AKI) is a well-recognized complication of severe malaria in adults; but the clinical importance of AKI in paediatric severe malaria is not well documented. Knowledge of the prevalence and factors associated with AKI among children with severe malaria is among the key strategies, which can help to reduce the burden of AKI among this vulnerable group. Methodology. A hospital-based prospective cross-sectional descriptive and analytic study of children with severe malaria was carried out at Kiryandongo General Hospital. The study involved 350 children with severe malaria attending the study site from August to October 2021. Questionnaires were administered to caretakers to obtain sociodemographic characteristics. Medical data were obtained through physical examination followed by laboratory tests. Blood samples were tested for creatinine and blood smear for malaria. Data were analyzed using binary logistic regression (bivariate and multivariate) to assess for the factors associated with AKI. A p value < 0.05 was considered statistically significant. Results: The mean age of children with severe malaria was 7.0 ± 3.8 years, and 54.3% of them were male. Of the 350 children enrolled, 167 had AKI, giving an overall AKI prevalence of 47.7% (95% CI: 42.5-53.0). The factors that were significantly associated with AKI among children with severe malaria included caretaker with no formal education (aOR = 21.0, 95% CI: 1.68-261.18, p = 0.018), caretaker with primary education level (aOR = 4.5, 95% CI: 1.41-14.12, p = 0.011), age of child < 5 years (aOR = 1.8, 95% CI: 1.07-2.88, p = 0.025), history of receiving NSAIDs (aOR = 5.6, 95% CI: 2.34-13.22, p < 0.001), moderate anemia (aOR = 3.1, 95% CI: 1.39-6.94, p = 0.006), and severe anemia (aOR = 3.8, 95% CI: 1.66-8.55, p = 0.002). Conclusion: The prevalence of AKI was high among children with severe malaria in Kiryandongo General Hospital. Acute kidney injury among children with severe malaria was associated with low level of education of caretakers, age of children less than 5 years, history of receiving NSAIDs, and anemia. The management of severe malaria should include screening for AKI especially in children under five years of age, anemic, and those who have received NSAIDs.

Bacteriology and Antibiotic Susceptibility Patterns among Neonates Diagnosed of Omphalitis at a Tertiary Special Care Baby Unit in Western Uganda.

BACKGROUND: Newborn infections remain a major cause of morbidity and mortality among neonates in low-income countries. Clinical diagnosis for omphalitis in such settings is possible but this does not depict the microbiological characteristics of the involved organisms, and clinicians have often prescribed empirical antibiotics in neonates with omphalitis, despite an increasing burden of antibiotic resistance. METHODS: A hospital-based cross-sectional study was conducted to evaluate the bacteriology and antibiotic susceptibility patterns among neonates diagnosed with omphalitis at the special care baby unit (SCBU) of Kampala International University-Teaching Hospital (KIU-TH), western Uganda from March to June 2019. Sixty-five (65) neonates with a clinical diagnosis of omphalitis were consecutively recruited in the study. Cord swabs were taken under sterile (aseptic) precautions from all neonates, and antibiotic susceptibility tests performed using the Kirby Bauer disk diffusion technique with commercially available antibiotics disks of ampicillin, cloxacillin, gentamicin, amikacin, cefotaxime, ceftriaxone, vancomycin, and imipenem on Mueller Hinton agar plates. The data was analyzed using STATA version 13.0, frequencies and proportions used to describe the variables. RESULTS: Fifty-five, 55 (84.6%), neonates with suspected omphalitis had positive cord swab culture. Staphylococcal aureus (58.2%) was the commonest cause of omphalitis followed by Neisseria spp (16.4%), E. coli 6 (10.9%), Proteus spp (5.5%), Klebsiella spp (3.6%), Citrobacter spp (3.6%), and Haemophilus spp (1.8%) in decreasing frequency. Isolates were resistant to ampicillin (87.7%), gentamicin (54.4%), and cloxacillin (34.4%), the drugs recommended for use in neonates with suspected omphalitis. CONCLUSIONS: Staphylococcal aureus is still the predominant cause of omphalitis among neonates. There was high resistance to the commonly used antibiotics in the treatment of omphalitis among newborns. This study reemphasizes that clinicians should do cord swabbing for both culture and susceptibility tests among newborns with suspected omphalitis before initiation of antibiotics.

Preterm Neonatal Mortality and Its Determinants at a Tertiary Hospital in Western Uganda: A Prospective Cohort Study.

BACKGROUND: Prematurity contributes greatly to the neonatal mortality burden in sub-Saharan Africa. This study evaluated the proportion of preterm neonatal death, medical conditions at admission, and determinants of mortality of preterm neonates in the neonatal intensive care unit (NICU) of a tertiary hospital in Western Uganda. MATERIALS AND METHODS: A prospective cohort study of 351 consecutively enrolled preterm neonates was conducted from March to June 2019. Interviewer-administered questionnaires and physical assessment of neonates were used to obtain socio-demographic and clinical data for mothers and their preterm neonates. Descriptive statistics for participants' characteristics were generated, while bivariate and multivariate logistic regression models were fitted so as to establish the determinants of mortality outcome. A p-value <0.05 was considered statistically significant. RESULTS: In-hospital neonatal mortality of 31.6% (95% CI: 26.9-36.7) was noted, with 65.8% of deaths occurring within 72 hours from admission. The most common medical conditions at admission were: hypothermia (67.2%), respiratory distress syndrome (43.0%), small for gestational age (15.7%), and perinatal asphyxia (14.5%). Under multivariate regression modelling, maternal age ≥35 years (AOR: 4.5; 95% CI: 1.35-15.31), no antenatal care (AOR: 4.7; 95% CI: 1.05-21.21), >4 ANC visits (AOR: 5.3; 95% CI: 1.88-15.21), neonatal resuscitation (AOR: 3.4; 95% CI: 1.66-6.82), outborn status (AOR: 2.3; 95% CI: 1.20-4.50), singleton pregnancy (AOR: 3.7; 95% CI: 1.74-7.89), <28 weeks' gestation (AOR: 12.0; 95% CI: 2.24-64.27), and male sex (AOR: 2.0; 95% CI: 1.04-3.74), respiratory distress syndrome (AOR: 2.6; 95% CI: 1.22-5.70), apnea (AOR: 6.2; 95.5% CI: 1.09-35.38), hypothermia (AOR: 2.3; 95% CI: 1.09-4.92), and small for gestational age (AOR: 4.7; 95% CI: 2.06-10.74) were significantly associated with mortality. CONCLUSION AND RECOMMENDATIONS: In-hospital mortality of preterm neonates was high. We identified various maternal and neonatal risk factors, indicating a need for stakeholders to enhance efforts towards prevention of preterm-associated complications and optimize facility-based continuum of care.

Predictors of Premature Rupture of Membranes among Pregnant Women in Rural Uganda: A Cross-Sectional Study at a Tertiary Teaching Hospital.

BACKGROUND: Premature rupture of membranes (PROM) is a common condition in developed and developing countries and poses a serious threat to the maternal and fetal well-being if not properly managed. This study delineated the prevalence and predictors of PROM in the western part of Uganda so as to guide specific preventive measures. METHODS: A cross-sectional study design was conducted in the months of September 2019 to November 2019. A total of 334 pregnant women above 28 weeks of gestation admitted at the maternity ward of KIU-TH were consecutively enrolled. Interviewer-administered questionnaires were used to obtain the data. Descriptive statistics followed by binary logistic regression were conducted. All data analyses were conducted using STATA 14.2. RESULTS: Of the 334 pregnant women enrolled, the prevalence of PROM was found to be 13.8%. The significant independent predictors associated with lower odds of PROM were no history of urinary tract infection (UTI) in the month preceding enrollment into the study (aOR = 0.5, 95% CI: 0.22-0.69, p = 0.038) and gestational age of 37 weeks or more (aOR = 0.3, 95% CI: 0.14-0.71, p = 0.038) and gestational age of 37 weeks or more (aOR = 0.3, 95% CI: 0.14-0.71, p = 0.038) and gestational age of 37 weeks or more (aOR = 0.3, 95% CI: 0.14-0.71. CONCLUSIONS: Majorly urinary tract infections, low gestational age, and abortions influence premature rupture of membranes among women. There is a great need for continuous screening and prompt treatment of pregnant women for UTI especially those with history of 3 or more abortions at less than 34 weeks of gestation.

Sclerema Neonatorum in a Term Infant: A Case Report and Literature Review.

Sclerema neonatorum (SN) is a rare form of panniculitides with an obscure incidence, aetiology, and pathogenesis. This condition is peculiar to preterm neonates, especially those with comorbidities such as sepsis, congenital anomalies, congenital heart disease, and gastrointestinal and respiratory diseases. Usually, it presents within the first seven days of life, but may develop a few weeks later. Typically, SN manifests with diffuse hardening of the skin and subcutaneous tissues that subsequently bind to the underlying muscle and bone, often beginning in the buttocks, thighs, or trunk, and progressing to other body parts, but sparing the soles, palms, and genitalia. Diagnosis is based on clinical characteristics. It has been associated with a high mortality, despite aggressive use of various treatment modalities such as antibiotics, steroids, fresh blood transfusion, exchange blood transfusion, and intravenous immunoglobins. This is a report of a macrosomic term neonate who presented with typical clinical and histopathological features of SN.

Characteristics of HIV-Infected Children at Enrollment into Care and at Antiretroviral Therapy Initiation in Central Africa.

BACKGROUND: Despite the World Health Organization (WHO) regularly updating guidelines to recommend earlier initiation of antiretroviral therapy (ART) in children, timely enrollment into care and initiation of ART in sub-Saharan Africa in children lags behind that of adults. The impact of implementing increasingly less restrictive ART guidelines on ART initiation in Central Africa has not been described. MATERIALS AND METHODS: Data are from the Central Africa International Epidemiologic Databases to Evaluate AIDS (IeDEA) pediatric cohort of 3,426 children (0-15 years) entering HIV care at 15 sites in Burundi, DRC, and Rwanda. Measures include CD4 count, WHO clinical stage, age, and weight-for-age Z score (WAZ), each at enrollment into HIV care and at ART initiation. Changes in the medians or proportions of each measure by year of enrollment and year of ART initiation were assessed to capture potential impacts of changing ART guidelines. RESULTS: Median age at care enrollment decreased from 77.2 months in 2004-05 to 30.3 months in 2012-13. The median age at ART initiation (n = 2058) decreased from 83.0 months in 2004-05 to 66.9 months in 2012-13. The proportion of children ≤24 months of age at enrollment increased from 12.7% in 2004-05 to 46.7% in 2012-13, and from 9.6% in 2004-05 to 24.2% in 2012-13 for ART initiation. The median CD4 count at enrollment into care increased from 563 (IQR: 275, 901) in 2004-05 to 660 (IQR: 339, 1071) cells/µl in 2012-13, and the median CD4 count at ART initiation increased from 310 (IQR:167, 600) in 2004-05 to 589 (IQR: 315, 1113) cells/µl in 2012-13. From 2004-05 to 2012-13, median WAZ improved from -2 (IQR: -3.4, -1.1) to -1 (IQR: -2.5, -0.2) at enrollment in care and from -2 (IQR: -3.8, -1.6) to -1 (IQR: -2.6, -0.4) at ART initiation. DISCUSSION AND CONCLUSION: Although HIV-infected children ≤24 months of age accounted for half of all children enrolling in care in our cohort during 2012-13, they represented less than a quarter of all those who were initiated on ART during the same period. Further research is needed to identify barriers to timely diagnosis, linkage to care, and initiation of ART among children with HIV infection.

HIV infection among children and adolescents in Burundi, Cameroon, and the Democratic Republic of Congo.

Evidence demonstrates a substantial HIV epidemic among children and adolescents in countries with long-standing generalized HIV epidemics, where availability of prevention of mother-to-child transmission services has historically been limited. The objective of this research was to explore factors associated with antiretroviral therapy (ART) initiation and morbidity among HIV-infected surviving children 2-17 years of age attending HIV programs in Central Africa. Programmatic data from 404 children attending HIV programs in Burundi, Cameroon, and the Democratic Republic of Congo (DRC) were included in our evaluation. Children were followed prospectively from 2008 to 2011 according to each clinic's standard of care. Diagnosis at a reference hospital was significantly associated with not having initiated ART (adjusted odds ratio, AOR = 0.40; 95% confidence interval, CI, 0.24-0.67). Being seen at a clinic in Cameroon (AOR = 0.45; 95%CI = 0.24-0.85) and being in school were associated with decreased risk (AOR = 0.55; 95%CI = 0.31-0.96). Being ART-naïve (AOR = 1.88; 95%CI = 1.20-2.94) and being diagnosed at a reference hospital (AOR = 2.39; 95%CI = 1.29-4.41) or other testing facility (AOR = 2.86; 95%CI = 1.32-6.18) were associated with increased risk of having a morbid event at the initial visit. In longitudinal analysis of incident morbidity, we found a decreased risk associated with attending clinics in Cameroon (adjusted hazard ratio, AHR = 0.23; 95%CI = 0.11-0.46) and the DRC (AHR = 0.46; 95%CI = 0.29-0.74), and an increased risk associated with being ART-naïve (AHR = 1.83; 95%CI = 1.12-2.97). We found a high burden of HIV-related health problems among children receiving care in this setting. Children face significant barriers to accessing HIV services, and the HIV epidemic among surviving children in the Central African region has not been adequately evaluated nor addressed.

HIV type 1 diversity and antiretroviral drug resistance mutations in Burundi.

In 2002, an HIV surveillance study was performed among more than 5500 individuals representing the general population of urban and rural districts in Burundi. In this report, we genetically characterized a subset of the HIV-1-positive samples identified during this survey, including all the HIV-positive samples from Bujumbura, the capital city, and samples from one semiurban and one rural district. One hundred and nineteen samples were genetically characterized in the V3-V5 region of the env gene and/or in the protease and reverse transcriptase region of the pol gene. Phylogenetic analysis of 101 env/pol sequences revealed that the HIV-1 epidemic in Burundi was driven by subtype C (81.2%), followed by subtype A (7.9 %) and polC/envA recombinants (5.9%). One major mutation associated with resistance to antiretroviral drugs (ARVs) in the pol gene, as defined by the International AIDS Society Resistance Testing-USA panel, was observed in one individual, but many minor resistance-associated mutations were also present in the majority of the samples.
