Acid Suppression/C difficile and Adrenal Suppression/Topical Steroids

Briefly noted:

J Jimenez et al. (JPGN 2015; 61: 208-11) provide more data that gastric acid suppression is associated with an increase risk of Clostridium difficile infection (CDI). This was a retrospective case-control study with 138 children with CDI and 276 controls. After adjustment, acid-suppression therapy had a 1.8 Odds Ratio association with CDI.

S Harel et al. (JPGN 2015; 61: 190-3) in this retrospective ‘pilot’ study of  patients receiving topical budesonide for eosinophilic esophagitis, 6 of 14 (43%) had mild biochemical evidence of adrenal suppression, as measured by ACTH testing. Bottomline: a prospective study is likely needed to confirm or refute these findings. In the meanwhile, stress steroid coverage could be considered in patients on prolonged budesonide.

How to Incorporate Budesonide Foam into UC Treatment Algorithm

A recent study (Sandborn WJ, et al. Gastroenterol 2015; 148: 740-50, editorial 701-4) shows that budesonide foam can be helpful for patients with ulcerative proctitis and ulcerative proctosigmoiditis.

Design: Two identical randomized, double-blind, placebo-controlled trials examined the use of budesonide foam in 546 patients with mild to moderate ulcerative proctitis or ulcerative proctosigmoiditis.  Patients had at least 5 cm of involved mucosa but no more than 40 cm. Dosing: 2 mg/25 mL twice daily for 2 weeks, then once daily for 4 weeks. The primary endpoint of remission was defined as an endoscopy subscore of ≤1, rectal bleeding subscore of 0, and improvement or no change from baseline in stool frequency subscore of the Mayo score. It is noted that about 90% of patients had moderate Mayo endoscopy subscore at baseline.

Key findings:

  • Combining the results of the studies, 41.2% achieved the primary end point of remission at the end of 6 weeks, compared with 24.0% of placebo patients.
  • There were 10 patients (3.7%) with low morning cortisol (compared with 0.7% of placebo-treated patients) and 14% who had abnormal ACTH testing at 6 weeks (compared with 4% of placebo-treated patients), though there no reported signs/symptoms of adrenal suppression present.

The associated editorial suggests that budesonide could be implemented in patients who did not respond to 5-ASA topical therapy (suppository for proctitis and enema for proctosigmoiditis).  In addition, the editorial questions whether a single night-time administration may be more effective by maximizing adherence.

Bottomline: Budesonide foam was superior to placebo in this study and may eliminate the need for systemic steroid use.  As the editorial suggests, 5-ASA topical therapy likely should be considered as first-line treatment.
