Efficacy and safety of biologic therapy in microscopic colitis: systematic review and meta-analysis.

BACKGROUND: This systematic review and meta-analysis sought to evaluate the effectiveness and safety of biologic therapy in the treatment of steroid-refractory microscopic colitis (MC). METHODS: We searched MEDLINE, Embase, Web of Science, and Cochrane Central to identify articles and abstracts reporting efficacy or safety data on biologic use (infliximab, adalimumab, certolizumab, golimumab, vedolizumab, ustekinumab, and tofacitinib) for induction and maintenance of remission in MC. We assessed clinical remission and response rates and all reported adverse events (AEs). RESULTS: A total of 376 studies were screened yielding 13 articles (including four abstracts) with a combined information on 78 patients for efficacy and safety outcomes. Most studies were case series. Vedolizumab was used in five studies, adalimumab in three, and a combination of infliximab and adalimumab in five studies. The rates of remission were 66.08% (95% CI, 36.79-95.37%; I2 , 71%) at weeks 3-6 and 54.20% (95% CI, 39.39-69.01%; I2 , 0%) at weeks 12-16. Clinical response rates were 100% (95% CI, 88.04-100%; I2 , 0%) at weeks 3-6 and 67.20% (95% CI, 47.72-86.69%; I2 , 52%) at weeks 12-16. Most frequent AE was medication discontinuation with a pooled incidence of 16.1% (95% CI, 5.9-37.5%). No deaths attributable to biologic use were reported. The overall quality of evidence was very low due to the high risk of biases. CONCLUSION: Low-quality evidence supports the short-term efficacy of biologics in budesonide refractory MC. While our findings represent the most comprehensive evaluation of biologic therapy in severe MC, further research including randomized clinical trials is needed to better define the role of specific agents and long-term therapy.

Poisoned child: emergency room management.

Poisoning is one of the commonest pediatric emergencies. Most of poisonings in children below 5 years of age, are accidental and fortunately trivial, related to their exploratory nature. However a poisoned child may present as an acute emergency with or without multisystem involvement. The initial phase of management focuses on support of airways, breathing and cardiac function (ABCD of Resuscitation). The second phase includes Evaluation and Detoxification phase. The Evaluation phase involves identification and severity of toxic exposure. Recognizing a Toxidrome (constellation of the signs and symptoms seen with the ingestion of a particular poison) is particularly very helpful when the child presents with an unknown poisoning. Detoxification should proceed simultaneously. The current literature suggests that activated charcoal is the mainstay of GI decontarmination. Whole bowel Irrigation is a new addition to the armamentarium of GI decontamination. At present antidotes are available for few toxins only so the management remains supportive for most poisons.
