Correlation analysis of serum cytokine levels and immune inflammatory factors in cirrhotic portal hypertension.

BACKGROUND: To investigate alterations in immune-inflammatory factors and variables, including procalcitonin(PCT), prostaglandin E (PGE), and serum C-reactive protein (CRP) in individuals with cirrhotic portal hypertension. METHODS: From March 2020 to March 2025, 81 patientswith cirrhotic portal hypertension and 50 healthy volunteerswere hospitalised to our hospital. These people were divided into two groups: the portal hypertension group and thecontrol group. Aspartate aminotransferase (AST), albumin(ALB), total bilirubin (TBIL), alanine aminotransferase(ALT), and portal vein inner diameter (Pvd) were measured.Serum cytokines, including CRP PCT, and PGE, weremeasured, as well as the percentages of CD 4+/CD 8+ Tcells and CD 3+ , CD 4+ , and CD8+ T lymphocytes. RESULTS: The group with portal hypertension had considerablylower ALB than the control group (P< 0.05), whereas indicators including ALT, AST, TBIL, and Dpv were significantlyhigher in the portal hypertension group than in the controlgroup (P< 0.05). While cytokine markers, including CRPPCT, and PGE, were higher in the portal hypertension groupthan in the control group (P< 0.05), the numbers of CD3 +and CD4+ T lymphocyte subsets and CD4+/CD8+ T lymphocytes were considerably lower in the portal hypertensiongroup. With increasing liver function classification, the proportions of CD3+ and CD4+ T lymphocyte subsets, as wellas CD4+/CD 8+ T lymphocytes, decreased in patients. However, there was a statistically significant (P<0.05) increase in the levels of serum PCT, PGE, and CRP Spearmancorrelation analysis revealed that liver function classificationwas negatively correlated with immune indicators. CRP PCTand PGE levels were favourably connected with CD4+ andCD4+/CD 8+ values (P < 0.05). Dpv was shown to have anegative association with CD4+/CD8+ T cells and a positive correlation with PCT and PGE levels (P<0.05) accordingto Pearson correlation analysis. CONCLUSIONS: Patients with cirrhotic portal hypertensionmay experience immune dysfunction and cytokine disorders. These changes are related to liver function and portalvein pressure and can be used as reference indicators forevaluating a patient's condition in clinical practice.
