[Nutritional impact of inflammatory bowel diseases on children and adolescents]

Nutritional characteristic of children with inflammatory bowel disease in the nationwide inflammatory bowel disease registry from the Mediterranean region

BACKGROUND/OBJECTIVES

We analyzed the nationwide pediatric inflammatory bowel disease (PIBD) registry (1998-2016), to evaluate the nutritional status at the time of diagnosis.

SUBJECTS/METHODS

Nine types of nutritional status by the combination of weight-for-length (<2 years)/body mass index (>2 years) and length/height-for-age with three categories (<-2, -2 to 2, and >2 SD) were described. Malnutrition was defined by WHO criteria. Univariate and multivariate regression analysis was used to identify risk factors for malnutrition.

RESULTS

In total, 824 IBD patients (498 Ulcerative colitis (UC); 289 Crohn's Disease (CD); 37 Indeterminate Colitis (IC); 412 male; the median age 12.5 years) were eligible. The prevalence of eutrophy, wasting/thinness, stunting, overweight, tall stature, concurrent wasting/thinness and stunting, tall stature with overweight, tall stature with wasting/thinness, and short stature with overweight were 67.4%, 14.9%, 6.6%, 3.1%, 3.2%, 3.3%, 1.1%, 0.4%, and 0.1%, respectively. The prevalence of malnutrition was 32.7%, indicating a higher prevalence in CD (p < 0.001). Incidence of overweight was less common in the CD than UC and IC (p < 0.001). Multivariate analysis revealed that age of onset (>10 years), prepubertal stage, severe disease activity, perianal involvement, and high C reactive protein level were independently associated with malnutrition in pediatric IBD.

CONCLUSION

We showed the frequency of nutritional impairment in PIBD. The percentage of overweight subjects was lower than the other studies. The age of onset, disease activity, CRP level, perianal involvement, and pubertal stage were associated with a higher risk for developing malnutrition. Our results also confirmed that CD patients are particularly vulnerable to nutritional impairment.

The impact of abnormal BMI on surgical complications after pediatric colorectal surgery

BACKGROUND/PURPOSE

While childhood obesity is a growing problem, the implications of BMI on elective pediatric surgery remains poorly described. This study evaluates the impact of obesity on surgical outcomes after elective colorectal procedures.

METHODS

Children ages 2-18 years undergoing elective colorectal surgery for IBD were identified from the NSQIP-Pediatric database. Patients were classified as underweight (UW), normal weight (NW), overweight (OW) and obese (OB) based on their age- and sex-adjusted BMI. Postoperative complications were compared between cohorts.

RESULTS

858 patients (14.8% UW, 64.3% NW, 13.1% OW, 7.8% OB) were identified, with overall complications occurring in 15.3% and SSI in 10.1%. Obese/overweight patients had higher rates of deep incisional SSI (4.5%OB, 4.5%OW, 0%NW, p=0.002) and superficial wound disruption (5.4%OB, 5.8%OW, 1.6%NW, p=0.04). Incremental increase in BMI by 1.0kg/m² was associated with 4.3% increased likelihood of developing deep incisional SSI and 2.3% increase of superficial wound disruption. Obese/overweight children also had increased incidence of septic shock and UTI, as well as longer operative times, days of mechanical ventilation and LOS.

CONCLUSIONS

Increasing BMI was associated with increased wound complications in IBD patients undergoing elective intestinal surgery. Preoperative optimization and weight loss strategies may potentially reduce SSI and other infectious complications.

Pediatric Crohn's Disease in Bahrain

OBJECTIVES

Our study aimed to report the epidemiology, clinical presentations, diagnostic and therapeutic approaches, and outcomes of Crohn's disease (CD) in pediatric patients in Bahrain.

METHODS

We conducted a retrospective review of the medical records of patients with CD diagnosed in the pediatric department, Salmaniya Medical Complex, Bahrain, between 1984 and 2017. We used the data to calculate the annual incidence and cumulative prevalence. Data about gender, nationality, clinical presentation, age at presentation and diagnosis, duration of illness, consanguinity, family history, contact with smokers, and comorbidities were gathered. Results of hematological, biochemical, and serological tests were also collected. All radiological, endoscopic, and histopathological findings were reviewed. Data about medical therapy, relapse episodes, hospital admissions, complications, and outcomes were collected.

RESULTS

Of 108 pediatric patients diagnosed with inflammatory bowel disease (IBD), 51 (47.2%) patients had CD. The annual incidence was 1 in 100 000 per year (range = 0-5 patients/year) with significant rise on comparing the three decades (p = 0.0001). Prevalence was 9.32 patients per 100 000 pediatric populations. Thirty-four patients (66.7%) were males, and the median age was 18.5 years (range = 6.4-35.0). Common clinical presentations were recurrent abdominal pain and weight loss. Family history of IBD was found in 10 patients. One patient had positive antineutrophil cytoplasmic antibody. The terminal ileum was involved in 68.1%, colon in 63.8%, and perianal area in 17.0% patients. Biological therapy was used in five patients. Surgical intervention was required in six patients. The mean follow-up period was 9.2±5.6 years.

CONCLUSIONS

The clinical characteristics of our population are comparable to that reported in neighboring countries and worldwide.
