The role of hydrogen sulfide in the progression mechanisms of non-alcoholic steatohepatitis and chronic kidney disease.

OBJECTIVE

Introduction: The steady increase in the incidence of non-alcoholic steatohepatitis (NASH) on the background of obesity and chronic kidney disease (CKD) in people of working age in Ukraine. The aim: To establish the role of hydrogen sulfide in the mechanisms of mutual burden and progression of non-alcoholic steatohepatitis and chronic kidney disease in patients with obesity.

METHODS

Materials and methods: 114 patients with NASH were examined on the background of obesity of І-ІІ degree, including: 52 patients with NASH (group 1) (without accompanying CKD), 62 patients with NASH with a comorbid CKD І-ІІ degree (group 2). The control group consisted of 20 practically healthy persons (PHPs) of the corresponding age and sex.

RESULTS

Results: The obtained data testify that a significant increase in the synthesis of collagen and glycoproteins in patients with NASH, which arose on the background of obesity, that comorbid with CKD, which was accompanied by an ineffective resorption of newly formed collagen due to insufficient activation of collagenolysis and proteolysis, a significant imbalance in the system of connective tissue metabolism.

CONCLUSIONS

Conclusions: A significant increase in the synthesis of collagen and glycoproteins (fibronectin) in patients with NASH, which was observed on the background of obesity, was established, which is accompanied by an ineffective resorption of newly formed collagen due to inhibition of collagenolysis against activation of proteinase inhibitors (α2-MG).
