A PhD thesis in the Department of Biology investigated some immune-physiological vital signs in obese people associated with rheumatoid arthritis in Al-Najaf Governorate.
The thesis presented by the Hassanein Fadel Muhammad included measuring some biochemical markers such as insulin growth factor type I, lactoferrin, neopterin, and protein associated with retol-1, before and after gastric sleeve, as well as measuring some criteria associated with arthritis, including factors associated with arthritis (e.g. rheumatoid factor and ACCP protein.(
The results of the thesis showed that these vital signs and criteria are related to obesity and have complications such as diabetes, heart and arterial diseases, low immunity and arthritis, which indicates the possibility of predicting infection in obese people, while there was an improvement in those biochemical parameters after the sleeve gastrectomy and follow-up for nine months.
