ABSTRACT
Objective From May 2010 to May 2013 and from June 2013 to June 2016, we compared the clinical analysis of patients with necrotizing enterocolitis (NEC) in the Department of Pediatrics, studied incidence rate of NEC and the relationship between stages of NEC and prognosis, and compared the prognosis between the two three-year periods to provide the experience of diagnosis and treatment for clinical practice in the future. Methods The clinical data of patients diagnosed with NEC were retrospectively analyzed according to the diagnostic criteria of modified Bell staging classification using SPSS statistical software package. Early diagnosis rate and prognosis were compared between the two three-year periods. P＜0.05 showed that statistical significance was found. Results From May 2010 to May 2013, 40 cases of NEC were diagnosed in our hospital, among which 8 was in the first stage (20%),24 in the second stage (60%),and 8 in the third stage (20%) . The number of premature infants was 32, accounting for 80% , among which 25 cases were infants with very low birth weight accounting for 62.5% and 8 cases were full-term infants, accounting for 20% (P＜0.05) . In the study, 32 cases (80%) received traditional treatment, which was effective in stage Ⅰ. During the second stage, two abandoned the treatment was confirmed death in the follow-up, two underwent surgery successfully due to the progression of the disease and four (25%) died in the hospital. Statistic significance of treatment of internal medicine was found when comparing stage Ⅰ with stage Ⅱ (P＜0.05) . Ten children underwent surgery, among which one gave up treatment after the surgery because of financial problems and was found dead in the follow-up and four (60%) died in the hospital. The comparison of surgical treatment in patients in stage Ⅱ and Ⅲ showed no statistical significance (P＞0.05) . Fatality rates were statistically significant (P＜0.05) . From June 2013 to June 2016, 41 children were diagnosed with NEC in our hospital, including 24 cases in stage Ⅰ (59%), 14 in stage Ⅱ (34%), and 3 in stage Ⅲ (7%) . The number of premature infants was 33, accounting for 80%, among which 26 cases were infants with very low birth weight accounting for 62.5% and 8 cases were full-term infants, accounting for 20% (P＜0.05) . In the study, 35 cases (85.3%) received traditional treatment, which was effective in stage Ⅰ. During the second stage, one underwent surgery successfully due to the progression of the disease. Statistic significance of treatment of internal medicine was found when comparing stage Ⅰ with stage Ⅱ (P＜0.05) . Four children underwent surgery, among which one gave up treatment after the surgery because of financial problems and was found dead in the follow-up and the surgery was successful in other three. The comparison of surgical treatment in patients in stage Ⅱ and Ⅲ showed statistical significance (P＜0.05) . Fatality rates were statistically significant comparing the two three-year periods (P＜0.05) . The comparison of the rates of early diagnosis in the two three-year periods showed statistically significance (P＜0.001) . Conclusion Early diagnosis of NEC is the key to reduce mortality. Intestinal fatty acid binding protein (I-FABP) is a serological marker for early diagnosis of NEC. As an important factor, the reduction of the incidence of premature birth will result in the drop in the incidence of NEC.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the clinical value of intestinal fatty acid-binding protein (I-FABP) in full-term newborn infants with necrotizing enterocolitis (NEC).</p><p><b>METHODS</b>Forty-one full-term infants with a confirmed diagnosis of NEC from February 2012 to January 2014 were recruited as case group (stage I: 24 cases; stage II-III: 17 cases). Sixty-two children diagnosed with non-digestive diseases in the same period were recruited as the control group. Serum levels of I-FABP and C-reactive protein (CRP) were determined by enzyme-linked immunosorbent assay. The diagnostic value of I-FABP for NEC was assessed using the receiver operating characteristic (ROC) curve.</p><p><b>RESULTS</b>Stage I and stage II-III cases in the case group had significantly higher serum I-FABP levels than the control group (P<0.05), and stage II-III cases had significantly higher serum I-FABP levels than stage I cases (P<0.05). The area under the ROC curve for serum I-FABP was 0.85 (95% CI: 0.78-0.92), with the optimal cut-off point of 2.25 ng/mL. Under this cut-off point, the sensitivity and specificity were 80.49% and 70.19%, respectively. There was no significant difference in serum CRP level between the case and control groups (P>0.05).</p><p><b>CONCLUSIONS</b>In newborn infants with NEC, serum I-FABP level increases significantly in stage I , and it is correlated with the disease severity. Therefore, serum I-FABP can be used as a biomarker for the diagnosis of NEC.</p>
