The aim of this study is to assess the usefulness of determining levels of myostatin (MSTN) and activin A (Act A) as potential markers of disease activity and occurrence of sarcopenia in Crohn\u2019s disease and ulcerative colitis patients. The case-control study included 82 patients with Inflammatory Bowel Disease. The control group consisted of 25 healthy volunteers. The serum levels of myostatin and activin A were determined by the quantitative sandwich enzyme-linked immunosorbent assay. Sarcopenia was diagnosed based on the EWGSOP2 criteria. The study found lower levels of myostatin and activin A in the IBD patients. There were significantly lower levels of myostatin (80.6 pg\/mL vs. 186.2 pg\/mL; p = 0.0364) as well as activin A (32.1 pg\/mL vs. 35.2 pg\/mL; p = 0.0132) in the IBD patients with sarcopenia compared to those without sarcopenia. Positive correlations were found between MSTN levels and Muscle Mass Index (rho = 0.31; p &lt; 0.005) and hand grip strength (rho = 0.34, p &lt; 0.05) in the IBD patients. The determination of serum levels of MSTN and Act A may be useful in the early diagnosis of sarcopenia in IBD patients.<\/jats:p>","DOI":"10.3390\/nu16060810","type":"journal-article","created":{"date-parts":[[2024,3,12]],"date-time":"2024-03-12T12:17:16Z","timestamp":1710245836000},"page":"810","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Myostatin and Activin A as Biomarkers of Sarcopenia in Inflammatory Bowel Disease Patients"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3579-8537","authenticated-orcid":false,"given":"Ma\u0142gorzata","family":"Godala","sequence":"first","affiliation":[{"name":"Department of Nutrition and Epidemiology, Medical University of Lodz, 90-752 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7568-3502","authenticated-orcid":false,"given":"Ewelina","family":"Gaszy\u0144ska","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Epidemiology, Medical University of Lodz, 90-752 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Konrad","family":"Walczak","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine and Nephrodiabetology, Medical University of Lodz, 90-549 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1825-1807","authenticated-orcid":false,"given":"Ewa","family":"Ma\u0142ecka-Wojciesko","sequence":"additional","affiliation":[{"name":"Department of Digestive Tract Diseases, Medical University of Lodz, 90-153 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Green, N., Miller, T., Suskind, D., and Lee, D.
