Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Obesity is an important public health problem worldwide. There are large regional differences in the prevalence of overweight and obesity. Obesity is a growing problem in both developed and low-income countries. Obesity is a common condition characterized by excessive fat accumulation in adipose tissue. It is associated with metabolic, hematological and musculoskeletal complications, increased risk of dyslipidemia, heart disease, diabetes and some malignancies, leading to a shortened life span. Inflammation from adipose tissue has been identified as the main source of systemic inflammation and may also be associated with insulin resistance. Adipocytes and adipose tissue-related macrophages from obese individuals are an important source of inflammatory mediators such as TNF-α, IL-6, IL-1 and MCP-1. It has also been shown that decreased levels of IL-10, an anti-inflammatory cytokine, are associated with obesity and metabolic syndrome.We aimed to evaluate changes in 13 different proinflammatory and anti-inflammatory cytokines in patients who underwent sleeve gastrectomy or gastric bypass.

Obesity is an important public health problem worldwide. There are large regional differences in the prevalence of overweight and obesity. Obesity is a growing problem in both developed and low-income countries. Obesity is a common condition characterized by excessive fat accumulation in adipose tissue. It is associated with metabolic, hematological and musculoskeletal complications, increased risk of dyslipidemia, heart disease, diabetes and some malignancies, leading to a shortened life span. Inflammation from adipose tissue has been identified as the main source of systemic inflammation and may also be associated with insulin resistance. Adipocytes and adipose tissue-related macrophages from obese individuals are an important source of inflammatory mediators such as TNF-α, IL-6, IL-1 and MCP-1. It has also been shown that decreased levels of IL-10, an anti-inflammatory cytokine, are associated with obesity and metabolic syndrome.There are many studies examining the changes in the weight and blood values of patients after bariatric surgery. Among these blood values, cytokines, which are inflammation mediators, were evaluated. However, in these studies, either sleeve gastrectomy or gastric bypass was evaluated separately and generally focused on TNF-α, IL-6, IL-1, IL10, and MCP-1 cytokines. There are conflicting results regarding the parameters examined in these studies. In some studies, no difference was found in the cytokines examined, while some regression was observed in proinflammatory cytokines. The situation is similar for IL10, which is one of the anti-inflammatory cytokines. An increase in IL10 values was observed in a study evaluating patients who underwent gastritic bypass, whereas no difference was found in a study evaluating sleeve gastrectomy patients.We aimed to evaluate changes in 13 different proinflammatory and anti-inflammatory cytokines before and 6 month after the surgery in patients who underwent sleeve gastrectomy or gastric bypass
