Abstract

Necrotizing enterocolitis (NEC) is an extremely severe clinical entity in whose pathogenesis at least two of the following factors are involved: intestinal ischaemia, pathogenic bacterial colonization and excessive substrate in the intestinal contents. Common risk factors are prematurity, rapid increase of feeding volume, polycythemia and perinatal asphyxia. Clinical features are abdominal distention, gastric retention, bloody stools and intestinal wall pneumatosis; while its complications are bowel perforation, peritonitis and shock. Early diagnosis allows prompt medical treatment based upon intestinal rest, no oral feeding, parenteral hydration and nutrition, nasogastric intubation, broad spectrum antibiotics and close surveillance. Surgery is kept to treat complications. Prevention includes feeding with human milk in prematures with slow increase of partial and total volumes, early initial fastening in cases of asphyxia and careful and close surveillance of high-risk newborns.

Epidemiology and outcome of "early-onset" vs "late-onset" necrotizing enterocolitis.

OBJECTIVE: We hypothesized that among neonates with necrotizing enterocolitis (NEC), important epidemiologic and outcome differences exist between those with early-onset vs. those with late-onset NEC. METHODS: We reviewed all records of neonates cared for in the King Fahad University Hospital during the past ten years who had the diagnosis of NEC. We separated cases into two groups depending on age at diagnosis. Specifically, we termed "early-onset" those cases diagnosed during the first seven days of life, and "late-onset" those diagnosed thereafter. We compared, in the two groups, gestational age, clinical signs at onset, laboratory data, surgical findings, complications, and mortality. RESULTS: From 1989 to 1999, 37 cases of stage IIa (or higher) NEC were diagnosed; 25 "early-onset" and 12 "late-onset". Neonates with "early-onset" NEC were more mature (35.4 +/- 2.5 weeks gestation) than those with "late-onset" (27.7 +/- 2.8 weeks, P=0.0001), were more likely to have feedings begun in the first 48 hours of life (P = 0.0002), and more likely to have feeding increments of >25 ml/kg/day (P=0.03). Neonates with "late-onset" NEC were more likely to present with vomiting (P=0.003) and apnea (P=0.001), and were more likely to have ileal rather than colonic necrotic lesions, short bowel syndrome, and mortality (P=0.03). CONCLUSION: During the past 10 years at the King Fahad University Hospital, cases of early- and late-onset NEC have had distinct epidemiologic and outcome features. Recognizing these differences may be useful in prognostication and counseling.

Recurrent pseudomembranous colitis as a cause of recurrent severe sepsis.

Clostridium difficile (C. difficile) colitis accounts for nearly 15-20 % of antibiotic-associated diarrhea. Manifestations include asymptomatic carriage, self-limited diarrhea, and pseudomembranous colitis, which is sometimes life-threatening. Despite effective therapy with metronidazole and vancomycin relapse rates are 15-33 %. Although colitis is seen in critically ill patients treated with combinations of broad-spectrum antibiotics, reports describing severe sepsis as a result of C. difficile infection are limited. We describe the case of recurrent severe sepsis due to recurrent local intestinal C. difficile infection as the only identifiable etiology. The mechanism of severe sepsis may be a derangement of the gastrointestinal barrier function. This could result in absorption of microbes or endotoxin or activation of inflammatory cascades in the submucosa of the intestine or liver. In general, for successful treatment of C. difficile infections other than anticlostridial antibiotics should be discontinued. However, in the present case bacterial translocation from the intestine is an attractive explanation for severe sepsis and therefore additional antibiotics had been administered.
