BACKGROUND
Vedolizumab is a humanized gut selective drug that specifically targets α4β7 integrin and has been used successfully in the treatment of Inflammatory Bowel Disease (IBD). Although Vedolizumab is an effective treatment for IBD and acts specifically on the gastrointestinal system, some studies have reported extraintestinal manifestations as adverse events. One of the most frequently reported non-infectious adverse events is articular manifestations. However, it is difficult to know for sure whether the joint symptoms are due to the vedolizumab adverse event or due to extraintestinal symptoms of the disease itself.
AIMS
This systematic review and meta-analysis aimed to assess the incidence of extraintestinal manifestations in patients receiving Vedolizumab and to investigate whether these adverse events are indeed drug-related.
METHODS
Pubmed, Cochrane, and Scopus were searched for randomized clinical trials reporting the incidence of articular events in patients with Crohn’s Disease or Ulcerative Colitis who were treated with Vedolizumab. The considered outcomes were new-onset or worsening of pre-existing joint manifestations. We used Revman to calculate the pooled incidence of the reported outcomes and their corresponding 95% confidence intervals (95% CI).
RESULTS
The search strategy yielded 4.206 articles. After removal of duplicates and screening of results, 4 randomized studies met the inclusion criteria (Figure 1).
A total of 2.466 patients with moderately to severe IBD were included. Of those, 1822 were randomized to intervention group, with Vedolizumab administration, and 644 to placebo. In the intervention group, 232 patients developed arthritis or arthralgia of any kind, versus 66 patients of placebo group (95% CI 0.7%-1.3%; Figure 2). Of those patients, 73,8% and 33% had prior treatment with anti-TNF and immunomodulators, respectively. 63% and 15% also had prior anti-TNF and immunomodulators previous failure, respectively.
CONCLUSION
The meta-analysis presented above shows a result without statistical significance to say that vedolizumab is responsible for the manifestations previously described. Therefore, it is necessary to hypothesize that the new onset of worsening arthritis and arthralgia may be associated with the course of the disease itself, the body's response to the drugs or the exclusion of corticosteroids or anti-TNF from concomitant treatment with Vedolizumab. More studies with larger samples are needed, especially randomized clinical trials comparing Anti-TNF, corticosteroids and immunomodulators to assess the incidence of joint manifestations and even other rheumatologic manifestations in patients with Inflammatory Bowel Disease.
Sarcoidosis is a multisystemic noncaseating granulomatous disease of unknown etiology. Cardiac sarcoidosis clinical presentation is diverse, and syncope is one of the possible primary events. Due to its variable natural history and initial presentation associated with lacking sensitive and specific diagnostic tests, it still represents a challenging diagnosis. This article presents the case of a 51-year-old female patient with intermittent syncope events associated with torsades de pointes and dilated cardiomyopathy compatible with sarcoidosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
