The Risk of Adverse Neonatal Outcomes With Maternal Inflammatory Bowel Disease: A Systematic Review and Meta-analysis.

BACKGROUND: Patients with inflammatory bowel disease (IBD) may be at increased risk of adverse neonatal outcomes. The aim of this study was to determine pooled incidences and risk factors for these outcomes. METHODS: Medline, Embase, and Cochrane Library were searched through May 2019 for studies reporting adverse neonatal outcomes in IBD. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. RESULTS: The pooled incidence of preterm birth, low birth weight, congenital anomalies, and infants transferred to the neonatal intensive care unit was 8.6% (95% CI, 7.0%-10.1%), 8.9% (95% CI, 7.3%-10.5%), 2.1% (95% CI, 1.6%-2.6%), and 4.9% (95% CI, 2.9%-6.9), respectively. Compared with healthy controls, patients with IBD were more likely to deliver infants with low birth weight (<2500 grams; OR, 2.78; 95% CI, 1.16-6.66) and infants admitted to the intensive care unit (OR, 3.33; 95% CI, 1.83-6.05). Patients with Crohn's disease had an increased incidence of congenital anomalies (OR, 3.03; 95% CI, 1.43-6.42). Among IBD patients, active disease was associated with increased incidence of preterm birth (OR, 2.06; 95% CI, 1.21-3.51), low birth weight (OR, 2.96; 95% CI, 1.54-5.70), and small for gestational age (OR, 2.62; 95% CI, 1.18-5.83). Antitumor necrosis factor (anti-TNF) use during pregnancy was associated with an increased incidence of neonatal intensive care unit admission (OR, 2.42; 95% CI, 1.31-4.45) and low birth weight (OR, 1.54; 95% CI, 1.01-2.35). CONCLUSIONS: Patients with IBD, particularly with active disease or requiring anti-TNF therapy, may be at increased risk of developing adverse neonatal outcomes.

Risk Factors for Developing Hidradenitis Suppurativa in Patients With Inflammatory Bowel Disease: A Retrospective Case-Control Study.

BACKGROUND: Hidradenitis suppurativa (HS) is associated with inflammatory bowel disease (IBD), though risk factors remain to be determined. AIM: To characterize HS among a cohort of IBD patients and identify risk factors for its development. METHODS: This was a retrospective case-control study at the ambulatory IBD centre at Mount Sinai Hospital from inception to May 2019. Patients with IBD who developed HS were included. Cases were matched 5:1 by age, gender (male versus female) and IBD type (ulcerative colitis [UC] or Crohn's disease [CD]) to controls who had IBD without HS. Conditional logistic regression was used to calculate odds ratios (ORs) with 95% confidence intervals (95% CIs). RESULTS: Twenty-nine cases of HS (19 CD and 10 UC) and 145 controls were included. Of the 29 patients with HS, 11 (37.9%) were male and 18 (62.1%) were female. The severity of HS was mild in 10 (34.5%), moderate in 16 (55.2%) and severe in 3 (10.3%) patients. Patients with HS and IBD were more likely to be active (OR 10.3, 95% CI 2.0 to 54.0, P = 0.006) or past (OR 8.4, 95% CI 2.7 to 25.8, P < 0.005) smokers. Patients with HS and IBD were also more likely to have active endoscopic disease (OR 3.8, 95% CI 1.2 to 12.2, P = 0.022). Furthermore, those with HS and CD were more likely to have active perianal disease (OR 21.1, 95% CI 6.2 to 71.9, P < 0.005). CONCLUSIONS: Active IBD, perianal disease and smoking may be associated with HS in IBD. Larger studies are needed to better characterize this morbid condition.

Systematic review with meta-analysis: risk of adverse pregnancy-related outcomes in inflammatory bowel disease.

BACKGROUND: The effect of inflammatory bowel disease (IBD) on pregnancy-related outcomes remains unknown. AIM: To determine the risk of adverse maternal, placental and obstetric outcomes in IBD METHODS: We searched Medline, Embase and Cochrane library through May 2019 for studies reporting adverse maternal, placental and obstetric outcomes in patients with IBD. Odds ratios (OR) with 95% confidence intervals (CI) were calculated for these outcomes in patients with IBD compared to healthy controls. RESULTS: Fifty-three studies were included (7917 IBD pregnancies and 3253 healthy control pregnancies). Caesarean delivery was more common in patients with IBD compared to healthy controls (OR 1.79, 95% CI, 1.16-2.77). This remained significant for UC (OR 1.80, 95% CI, 1.21-2.90) but not CD (OR 1.48, 95% CI, 0.94-2.34). Similarly, gestational diabetes occurred more commonly in IBD (OR 2.96, 95% CI, 1.47-5.98). The incidences of placental diseases were 2.0% (95% CI, 0.9%-3.1%) for pre-eclampsia, 3.3% (95% CI, 0%-7.2%) for placental abruption, 0.5% (95% CI, 0.2%-0.9%) for placenta previa and 0.3% (95% CI, 0%-0.5%) for chorioamnionitis. Patients with IBD were more likely to experience preterm prelabour rupture of membranes (OR 12.10, 95% CI, 2.15-67.98), but not early pregnancy loss (OR 1.63, 95% CI 0.49-5.43). Anti-tumour necrosis factor therapy was not associated with chorioamnionitis (OR 1.12, 95% CI, 0.16-7.67), early pregnancy loss (OR 1.49, 95% CI, 0.83-2.64) or placenta previa (OR 1.58, 95% CI, 0.30-8.47). CONCLUSIONS: Gestational diabetes and preterm prelabour rupture of membranes occurs more commonly in patients with IBD, although the incidence of placental diseases remains low.

Pill-Induced Esophagitis From Intake of Dietary Supplements.

Cases of pill-induced esophagitis can be associated with significant acute symptoms leading to hospitalization and have resulted in mediastinal penetration and hemorrhage. Clinicians often consider the diagnosis in patients taking classically associated medications. However, because many patients take dietary supplements, it is important to consider these as a potential etiology in a patient presenting with esophageal symptoms. We present a case of pill-induced esophagitis in a 40-year-old woman after the ingestion of l-arginine, selenium, and vitamin E supplements. Literature review revealed 6 cases of l-arginine-induced esophagitis reported, and no previous cases associated with vitamin E or selenium.
