Haemodialysis in Diabetic Patients Modulates Inflammatory Cytokine Profile and T Cell Activation Status

Area of Science:

• Immunology
• Nephrology
• Clinical Medicine

Background:

• Diabetic nephropathy (DN) is a severe diabetes complication requiring renal replacement therapy.
• Patients with DN undergoing hemodialysis (HD) often experience immune system anomalies and infections.

Purpose of the Study:

• To evaluate T cell activation markers (CD25, CD69, CD71) and inflammatory cytokines (IL-12p70, IL-8, IL-10, IL-1β, TNF-α, IL-6) before and after a single HD session in DN patients.

Main Methods:

• Blood samples were collected from DN patients on HD before and after one session.
• T cell activation markers were analyzed using flow cytometry.
• Cytokine levels were quantified using the cytometric bead array technique.

Main Results:

• HD altered the CD4/CD8 T cell ratio.
• Significant increases in CD25+ T cells and CD8+ CD25+ cells were observed post-HD.
• Decreases in CD69 T cells, CD25 mean fluorescence intensity on CD4+ T cells, and CD71 expression were noted.
• IL-10 and IL-6 levels increased, while IL-8 levels decreased after HD.

Conclusions:

• A single hemodialysis session significantly affects T cell activation status in DN patients.
• HD differentially modulates the production of inflammatory cytokines in this patient group.
