Clinical and bacteriological profiles of neonatal sepsis in a tertiary hospital, south-western Nigeria.

Introduction: Antibiotic-resistant bacteria complicate treatment options in neonatal sepsis, especially in developing countries. This study determined the epidemiology and bacteriological characteristics of neonatal sepsis at a tertiary hospital, in southwest Nigeria. Methods: This was a cross-sectional study from December 2017 to April 2019 among admitted babies with clinical neonatal sepsis. Blood culture was performed by semi-automated system, sepsis biomarker assay (serum procalcitonin) by a semi-quantitative kit while proforma was used to capture clinico-demographic data. Bacterial identification, antibiotic susceptibility patterns, determination of genetic elements mediating resistance, were performed by standard methods and polymerase chain reaction protocols, respectively. Quantitative data were expressed as frequencies, mean; bivariate and multivariate analyses were performed by Chi-square or Fishers' exact test and logistic regression. Results: Of the 192 cases of neonatal sepsis enrolled, 42.7% (82/192) were blood culture positive. Factors associated with blood culture positivity included respiratory rate ≥60 bpm (60/82; p<0.03), lethargy/unconsciousness (59/82; FE=7.76; p<0.001), grunting respiration (54/82; p=0.04), meconium passage before birth (17/82; p=0.03) and prolonged rupture of membranes ≥24 hours (50/82; FE=6.90; p=0.01). On the other hand, mortality in the neonates was associated with elevated serum procalcitonin assay (>0.5 ng/mL) χ2=13.58; p=0.03] and Gram-negative bacteremia (χ2=24.64; p<0.001). The most common bacterial isolates were Staphylococcus aureus (42/82), coagulase-negative Staphylococcus spp. (17/82), Enterobacter spp. (8/82), and Acinetobacter spp. (6/82). Methicillin resistance was present in 85.7% (36/42) of Staphylococcus aureus and 52.9% (9/17) of coagulase-negative Staphylococcus, while extended-spectrum beta-lactamase (ESBL) and AmpC enzymes were present in (21.1%; 4/19) of the Gram-negative bacilli. Conclusions: Almost half of the cases of clinically diagnosed neonatal sepsis have bacterial etiologic confirmation of sepsis. Gram-negative bacteremia and high serum procalcitonin predict mortality in neonatal sepsis. There was high resistance to common antibiotics for the treatment of neonatal sepsis in our settings.

Rectal carriage of extended-spectrum ß-lactamase-producing Enterobacteriales among neonates admitted into a special care baby unit, southwest Nigeria.

BACKGROUND: The intestinal microbiota of neonates can be colonised by extended-spectrum ß-lactamase-producing Enterobacteriales (ESBL-PE) with the risks of subsequent infections. The antimicrobial resistance profile of the gut flora of neonates is not well defined in Nigeria. This study determined the burden of rectal carriage of ESBL-PE among neonates. METHODS: We conducted a prospective longitudinal study among neonates admitted into a tertiary hospital from September 2019 to November 2019. Stools were sampled at admission and weekly until exit and processed by standard laboratory methods including polymerase chain reaction to identify ESBL genes. The ESBL-PE colonisation period prevalence at admission and acquisition rate were determined. RESULTS: The period prevalence of the ESBL-PE colonisation and acquisition rate were 46.5% (59/127) and 34.6% (36/104), respectively. Prolonged rupture of the amniotic membrane (PROM; >24 h; p=0.004, odds ratio [OR] 0.297), number of neonates on admission in the same room (p<0.001, OR 0.053) and presence of an ESBL-PE colonisers (p=0.004, OR 0.272) were independent risk factors for ESBL-PE rectal colonisation. ESBL-PE colonisation did not correlate with mortality (Fisher's exact test 1.342, p=0.196). CONCLUSIONS: The rate of ESBL-PE neonatal rectal colonisation is high in our settings and this underscores the need for a review of neonatal admission protocols, embracing of antibiotic stewardship in the management of PROM, resistance surveillance and implementation of infection prevention and control in the neonatal unit.

Children and adolescents with type 1 diabetes mellitus in Nigeria: clinical characteristics and compliance with care.

OBJECTIVES: The prevalence of type 1 diabetes mellitus (T1DM) is increasing in most developed and developing countries. This study described the clinical characteristics and compliance with care among Nigerian children and adolescents with T1DM. METHODS: This was a cross-sectional descriptive multi-center study of children seen at the paediatric endocrinology clinic of seven selected tertiary health facilities in Nigeria. Information was collected on socio-demographics, clinical characteristics and compliance of the children with dietary recommendations and insulin therapy. Compliance with dietary recommendations and insulin therapy was graded as either good or poor based on defined criteria. RESULTS: The mean age of children was 13.1 ± 4.7 years. The mean age of children at the diagnosis of T1DM was 9.9 ± 4.2 years. Sixty-nine (60%) children were female while about half (47.8%) of the children were from the lower socioeconomic class. Compliance with insulin administration was good in 39.1% of the children and was significantly associated with the father's (p=0.001) and mother's educational status (p=0.024) while compliance with dietary recommendations was good in 20.0% of the children and was significantly associated with mother's educational status (p=0.034) and family socioeconomic class (p=0.010). Only the mother's level of education was independently and significantly associated with compliance to recommendations on insulin therapy (OR 4.2, 95% CI=1.5-11.6, p=0.007). CONCLUSIONS: The compliance of children with dietary recommendations and insulin therapy was poor. Efforts should be strengthened at all healthcare facilities to educate parents on the need for compliance with management guidelines.

Intracranial abscesses in children at Ile-Ife, Nigeria: a case series and review of literature.

PURPOSE: Central nervous system (CNS) infections are significant causes of morbidities and mortalities in children with some being prone to the development of abscesses which can either be within the brain parenchyma or located in extracranial structures. We aimed to describe the clinical profile and outcome of children with cranial abscesses at the Obafemi Awolowo University Teaching Hospital Complex (OAUTHC). METHODS: Consecutive cases presenting at the Children Emergency Ward of OAUTHC Ile-Ife were recruited. The pattern of presentation, predisposing factors and outcome of these children were studied. RESULTS: Among the 641 children admitted within a 6-month period, six were diagnosed with cranial abscess giving a hospital prevalence of 0.9%. The mean duration of symptom prior to presentation was 12.7 ± 13.4 days. Five (83.3%) of the patients had intracranial abscesses which were multiple in two (33.3%) children. One patient had Pott's puffy tumour following frontal sinusitis. Surgical management was done for two (33.3%), and this was by craniotomy and evacuation. Two of the patients died with a case fatality rate of 33.3%. CONCLUSION: Though uncommon, cranial abscesses remain life threatening in children especially in resource-poor settings. Early presentation and early treatment of local infections will improve outcome.
