Presentation and outcomes of early and late onset neonatal sepsis in a Nigerian Hospital.

BACKGROUND: Neonatal Sepsis remains a major cause of morbidity and mortality in neonates despite great advances in antimicrobial therapy and life support measures. OBJECTIVES: To compare the aetiology, risk factors, presentation and outcomes of care between early onset neonatal sepsis (EOS) and late onset neonatal sepsis (LOS). METHODS: Bacterial isolates were identified using blood cultures and antibiotic susceptibility testing was done using disc diffusion method. The risk factors, clinical presentation, laboratory findings and neonatal outcomes of the babies with EOS were compared with LOS. Statistical significance was set at P <0.05. RESULTS: Neonatal Sepsis was responsible for 16% of Special Care Baby Unit (SCBU) admissions. Of the 72 babies with sepsis, 56 (77.8%) had EOS as against 16 (22.2%) who had late-onset sepsis. Low birth weight (p=0.01) and perinatal asphyxia (p=0.01) were significantly associated with EOS while for LOS, delivery outside the health facility (p=0.01) was the only significant risk factor. Respiratory distress was more significantly observed in EOS (p = 0.01). Neonatal deaths occurred in 32% of babies with EOS while all babies with culture positive LOS survived. CONCLUSION: Early onset neonatal sepsis is associated with high likelihood of neonatal mortality. Unsupervised delivery, birth asphyxia and low birth weight are risk factors associated with neonatal sepsis. Efforts to ensure supervised hospital delivery and improvement in neonatal resuscitation may reduce the incidence of neonatal sepsis and its attendant complications.

Invasive bacteria isolates from children with severe infections in a Nigerian hospital.

BACKGROUND: Little information is available about the aetiology and epidemiology of serious bacterial infections in Nigeria. This study determined bacterial isolates from blood and cerebrospinal fluid (CSF) of children presenting in the emergency room of a teaching hospital in Nigeria. METHOD: From October 2005 to December 2006, children aged two to 60 months presenting with signs of acute systemic infections were recruited. Blood culture and CSF specimens were collected and processed using standard microbiological protocols. Data were analysed using SPSS version 11 software. RESULTS: Two hundred and two blood and 69 CSF samples were cultured. Fifty-five (27%) of the blood cultures yielded Gram-negative bacilli and Gram-positive cocci in almost equal proportions. The most common isolates from the blood cultures were Staphylococcus aureus, 26 (12.9%) and atypical coliforms, 13 (6.5%). Others are Klebsiella spp, 3 (1.5%); Klebsiella pneumonia, 2 (1.0%); Escherichia coli, 3 (1.5%); Enterobacter agglomerans, 2 (1.1%); Proteus mirabilis, 2(1%); Pseudomonas spp, 2 (1.0%); Haemophilus influenza, 1 (1.0%); and Coagulase-negative Staphylococcus, 1 (1.0%). Fourteen out of 67 (20.9%) of the CSF samples yielded bacterial isolates: Streptococcus pneumonia, 3 (4.5%); Haemophilus influenza, 8 (11.9%); Hemophilus spp, 1 (1.5%); E. Coli, 1 (1.5%); and atypical coliform, 1 (1.5%). Gram-negative coliform isolates were predominantly resistant to penicillin based antibiotics and co-trimoxazole but sensitive to third-generation cephalosporins and quinolones. A high percentage of S. aureus isolates were multi-drug resistant. CONCLUSIONS: Bacterial infections contribute to the significant morbidity among children in our environment. S. aureus was more frequently isolated in sepsis while H. influenzae appears to play a major role in meningitis. Appropriate use of antibiotics is needed to manage affected children effectively. We also recommend improved vaccine coverage of children under the age of five years.

Effectiveness of dried Carica papaya seeds against human intestinal parasitosis: a pilot study.

The tropical fruit Carica papaya and its seeds have proven antihelminthic and anti-amoebic activities. To determine the effectiveness of air-dried C. papaya seeds on human intestinal parasitosis, 60 asymptomatic Nigerian children with stool microscopic evidence of intestinal parasites received immediate doses (20 mL) of either an elixir composed with air-dried C. papaya seeds and honey (CPH) or honey alone (placebo) in two randomized treatment groups. Repeat stool microscopic examinations were conducted 7 days postintervention for intestinal parasites. Significantly more subjects given CPH elixir than those given honey had their stools cleared of parasites [23 of 30 (76.7%) vs. five of 30 (16.7%); z = 4.40, P = .0000109]. There were no harmful effects. The stool clearance rate for the various types of parasites encountered was between 71.4% and 100% following CPH elixir treatment compared with 0-15.4% with honey. Thus, air-dried C. papaya seeds are efficacious in treating human intestinal parasites and without significant side effects. Their consumption offers a cheap, natural, harmless, readily available monotherapy and preventive strategy against intestinal parasitosis, especially in tropical communities. Further and large-scale intervention studies to compare C. papaya with standard antiparasitic preparation are desirous.
