In addition to further increasing the risk of developing cardiovascular diseases (CVDs) in this group of patients, obesity is associated with higher disease activity and a lower response to drug therapy. This case series showed that in those patients with rheumatoid arthritis or psoriatic arthritis with a substantial weight loss of &gt;10% of body mass, median Disease Activity Score 28 joints score decreased with 0.9. This reduction in disease activity resulted in an increase in the percentage of patients achieving remission from 6% to 63%. This reduction in disease activity was obtained without intensification of medical treatment in 87% of the patients. This case series supports the current evidence that weight reduction has positive effects on the course of the disease and thus also on the CVD risk profile in these patients. Therefore, weight loss can serve as a non-pharmacological treatment option in obese patients with IRDs.<\/jats:p>","DOI":"10.1136\/rmdopen-2020-001498","type":"journal-article","created":{"date-parts":[[2021,1,27]],"date-time":"2021-01-27T12:11:05Z","timestamp":1611749465000},"page":"e001498","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":24,"title":["Effect of significant weight loss on disease activity: reason to implement this non-pharmaceutical intervention in daily clinical practice"],"prefix":"10.1136","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9756-9639","authenticated-orcid":false,"given":"Julia M","family":"Weijers","sequence":"first","affiliation":[{"name":"Department of IQ Healthcare, Radboudumc, Nijmegen, Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wieland D","family":"M\u00fcskens","sequence":"additional","affiliation":[{"name":"Department of IQ Healthcare, Radboudumc, Nijmegen, Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Piet L C M","family":"van Riel","sequence":"additional","affiliation":[{"name":"Department of IQ Healthcare, Radboudumc, Nijmegen, Netherlands"},{"name":"Department of Rheumatology, Ziekenhuis Bernhoven, Uden, Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2021,1,27]]},"reference":[{"key":"2025090312245195000_7.1.e001498.1","unstructured":"World Health Organization .
