Time to full enteral feeds in hospitalised preterm and very low birth weight infants in Nigeria and Kenya

Background: Preterm (born < 37 weeks’ gestation) and very low birthweight (VLBW; <1.5kg) infants are at the greatest risk of morbidity and mortality within the first 28 days of life. Establishing full enteral feeds is a vital aspect of their clinical care. Evidence predominantly from high income countries shows that early and rapid advancement of feeds is safe and reduces length of hospital stay and adverse health outcomes. However, there are limited data on feeding practices and factors that influence the attainment of full enteral feeds among these vulnerable infants in sub-Saharan Africa. Aim: To identify factors that influence the time to full enteral feeds, defined as tolerance of 120ml/kg/day, in hospitalised preterm and VLBW infants in neonatal units in two sub-Saharan African countries. Methods: Demographic and clinical variables were collected for newborns admitted to 7 neonatal units in Nigeria and Kenya over 6-months. Multiple linear regression analysis was conducted to identify factors independently associated with time to full enteral feeds. Results: Of the 2280 newborn infants admitted, 484 were preterm and VLBW. Overall, 222/484 (45.8%) infants died with over half of the deaths (136/222; 61.7%) occurring before the first feed. The median (inter-quartile range) time to first feed was 46 (27, 72) hours of life and time to full enteral feeds (tFEF) was 8 (4.5,12) days with marked variation between neonatal units. Independent predictors of tFEF were time to first feed (unstandardised coefficient B 1.69; 95% CI 1.11 to 2.26; p value <0.001), gestational age (1.77; 0.72 to 2.81; <0.001), the occurrence of respiratory distress (-1.89; -3.50 to -0.79; <0.002) and necrotising enterocolitis (4.31; 1.00 to 7.62; <0.011). Conclusion: The use of standardised feeding guidelines may decrease variations in clinical practice, shorten tFEF and thereby improve preterm and VLBW outcomes

Prospective observational study of the challenges in diagnosing common neonatal conditions in Nigeria and Kenya

Objectives: Accurate and timely diagnosis of common neonatal conditions is crucial for reducing neonatal deaths. In low/middle-income countries with limited resources, there is sparse information on how neonatal diagnoses are made. The aim of this study was to describe the diagnostic criteria used for common conditions in neonatal units (NNUs) in Nigeria and Kenya. Design: Prospective observational study. Standard case report forms for suspected sepsis, respiratory disorders, birth asphyxia and abdominal conditions were co-developed by the Neonatal Nutrition Network (https://www.lstmed.ac.uk/nnu) collaborators. Clinicians completed forms for all admissions to their NNUs. Key data were displayed using heatmaps. Setting: Five NNUs in Nigeria and two in Kenya comprising the Neonatal Nutrition Network. Participants: 2851 neonates, which included all neonates admitted to the seven NNUs over a 6-month period. Results: 1230 (43.1%) neonates had suspected sepsis, 874 (30.6%) respiratory conditions, 587 (20.6%) birth asphyxia and 71 (2.5%) abdominal conditions. For all conditions and across all NNUs, clinical criteria were used consistently with sparse use of laboratory and radiological criteria. Conclusion: Our findings highlight the reliance on clinical criteria and extremely limited use of diagnostic technologies for common conditions in NNUs in sub-Saharan Africa. This has implications for the management of neonatal conditions which often have overlapping clinical features. Strategies for implementation of diagnostic pathways and investment in affordable and sustainable diagnostics are needed to improve care for these vulnerable infants

Case Report: An unusual case of bee envenomation presenting with acute kidney injury, cavernous venous thrombosis and multiple episodes of convulsions

Bee stings are common in the tropics and cause minor problems but may occasionally cause severe anaphylactoid reactions.Summary of clinical case: We present a case of M.O.O., an 8-year-old boy who was stung three times on the face and developed severe manifestations including acute kidney injury, cavernous sinus thrombosis and multiple convulsions but recovered without sequelae.Discussion: There is an association between the severity of reaction and the number of bee stings but this case was unique in the sense that we had only 3 stings reported and we developed life threatening clinical manifestations.</p

Molecular surveillance reveals widespread colonisation by carbapenemase and extended spectrum beta-lactamase producing organisms in neonatal units in Kenya and Nigeria

AbstractObjectivesNeonatal sepsis, a major cause of death amongst infants in sub-Saharan Africa, is often gut derived. Impairments in immunity and the gut barrier in sick neonates allow colonisation by opportunistic pathogens such as Enterobacteriaceae to progress to blood stream infection. Colonisation by Enterobacteriaceae producing extended spectrum beta-lactamase (ESBL) or carbapenemase enzymes is particularly problematic and can lead to antimicrobial-resistant (AMR) or untreatable infections. We sought to explore the rates of colonisation by ESBL or carbapenemase producers and their genotypes in two neonatal units (NNUs) in West and East Africa.MethodsStool and rectal swab samples were taken at multiple timepoints from newborns admitted to the NNUs at the University College Hospital, Ibadan, Nigeria and the Jaramogi Oginga Odinga Teaching and Referral Hospital, Kisumu, western Kenya. Samples were tested for ESBL and carbapenemase genes using a previously validated qPCR assay with high resolution melt analysis. Kaplan-Meier survival analysis was used to examine colonisation rates at both sites.ResultsA total of 119 stool and rectal swab samples were taken from 42 infants admitted to the two NNUs. Six (14.3%) infants were extremely preterm (gestation &lt;28 weeks), 19 (45.2%) were born by Caesarean section and 3 (8.6%) mothers were HIV positive. Median (IQR) duration of admission was 12.5 (5-26) days and 12 (28.6%) infants died. Overall, colonisation with ESBL (37 infants, 89%) was more common than with carbapenemase producers (26, 62.4%; P = 0.093). Median survival time before colonisation with ESBL organisms was 7 days and with carbapenemase producers 16 days (P=0.035). The majority of ESBL genes detected belonged to the CTX-M-1 (36/38; 95%), and CTX-M-9 (2/36; 5%) groups. The most prevalent carbapenemase was blaNDM (27/29, 93%). Single blaVIM (1/32, 3%) and blaOXA-48 genes (1/32, 3%) were also detected.ConclusionsGut colonisation of neonates by AMR organisms was common and occurred rapidly in NNUs in Kenya and Nigeria. Active surveillance of colonisation will improve the understanding of AMR in these settings and guide infection control and antibiotic prescribing practice to improve clinical outcomes.HighlightsColonisation with extended spectrum beta-lactamase (ESBL) or carbapenemase producing bacteria was common in two neonatal units in Kenya and NigeriaESBL colonisation occurred in 89% of neonates, with a median colonisation time of 7 daysColonisation with carbapenemase producers occurred in 62% of neonates, with a median time to colonisation of 16 daysThe most common ESBL genes detected were of the CTX-M-1 family, whilst the most common carbapenemase detected was blaNDM</jats:sec

Enteral Feeding Practices for Very Preterm and Very Low Birth Weight Infants in Nigeria and Kenya

Background:Optimizing nutrition in very preterm (28–32 weeks gestation) and very low birth weight (VLBW; 1,000 g to &amp;lt;1,500 g) infants has potential to improve their survival, growth, and long-term health outcomes.AimTo assess feeding practices in Nigeria and Kenya for very preterm and VLBW newborn infants.MethodsThis was a cross-sectional study where convenience sampling was used. A standard questionnaire was sent to doctors working in neonatal units in Nigeria and Kenya.ResultsOf 50 respondents, 37 (74.0%) were from Nigeria and 13 (26.0%) from Kenya. All initiated enteral feeds with breastmilk, with 24 (48.0%) initiating within 24 h. Only 28 (56.0%) used written feeding guidelines. Starting volumes ranged between 10 and 80 ml/kg/day. Median volume advancement of feeds was 20 ml/kg/day (IQR 10–20) with infants reaching full feeds in 8 days (IQR 6–12). 26 (52.0%) of the units fed the infants 2 hourly. Breastmilk fortification was practiced in 7 (14.0%) units, while folate, iron, calcium, and phosphorus were prescribed in 42 (84.0%), 36 (72.0%), 22 (44.0%), 5 (10.0%) of these units, respectively. No unit had access to donor breastmilk, and only 18 (36.0%) had storage facilities for expressed breastmilk. Twelve (24.0%) used wet nurses whilst 30 (60.0%) used formula feeds.ConclusionFeeding practices for very preterm and VLBW infants vary widely within Nigeria and Kenya, likely because of lack of locally generated evidence. High quality research that informs the feeding of these infants in the context of limited human resources, technology, and consumables, is urgently needed.</jats:sec
