Changes in the cytokine status in women with chronic liver pathology during reproductive losses in the first trimester

Research objective: to determine the level of serum cytokines in the pregravidar period in women with chronic diseases of the hepatobiliary system and reproductive losses in the first trimester in the anamnesis. Materials and methods. 90 patients of reproductive age with chronic pathology of the hepatobiliary system (liver steatosis and non-alcoholic steatohepatitis) were examined. All patients had spontaneous miscarriages in the early stages of gestation in anamnesis. The research was conducted during the pregravid preparation period. The laboratory research included an additional study of the interleukins (ІL-2, ІL-6, ІL-8, ІL-10) and tumor necrosis factor (TNFα) in the blood serum using enzyme immunoferment assay. 8 female donors were examined to determine the reference norm of cytokines in the blood serum. Results. The cytokine status in patients with chronic pathology of the hepatobiliary system against the background of early miscarriage was characterized by an increase in proinflammatory cytokines (TNFα in 2,29 times more, ІL-2 in 1,46 times, ІL-6 in 1,84 times and ІL-8 in 1,50 times) and anti-inflammatory cytokines (ІL-10 in 1,31 times). The integral indices that are characterizing the oppositional cytokines ratio increased (TNFα/ІL-10, ІL-2/ІL-10 and ІL-6/ІL-10) which indicates an inflammatory process in the body. Minimal changes were registered in patients with signs of steatosis – a moderate increase in proinflammatory cytokines (TNFα is 1,34 times more, ІL-2 in 1,18 times, ІL-6 in 1,33 times and ІL-8 in 1,13 times) and preservation within the reference norm of ІL-10. The maximum imbalance of serum cytokines was observed in the exacerbation of non-alcoholic steatohepatitis – a significant increase in proinflammatory cytokines (TNFα is 3,66 times more, ІL-2 in 1,95 times, ІL-6 in 2,57 times and ІL-8 in 2,18 times) against the background of a moderate increase in ІL-10 (1,30 times). In patients with clinical and laboratory signs of remission of non-alcoholic steatohepatitis a moderate increase in proinflammatory (TNFα is 1,87 times more, ІL-2 in 1,20 times, ІL-6 in 1,61 times and ІL-8 in 1,20 times) and anti-inflammatory (ІL-10 in 1,51 times) cytokines was diagnosed. The analysis of the integral indices of oppositional cytokines showed a tendency to increase their values in patients with liver steatosis and non-alcoholic steatohepatitis in the phase of clinical and laboratory remission. During the period of the non-alcoholic steatohepatitis exacerbation a considerable increase in the studied coefficients was revealed. Conclusions. Changes in the cytokine status are noted in patients with early spontaneous miscarriages in anamnesis and chronic diseases of the hepatobiliary system, which are characterized by the severity of inflammatory reactions and progression of the pathological process in liver. Obtained results can be used to predict miscarriage and be taken into account in the program of drug preparation in the pregravid period
