Abstract

Objective

To investigate the immune profiles in benign prostatic hyperplasia, changes in the absolute number of lymphocyte subsets and the proportion of T lymphocyte subsets were detected.

Methods

Absolute value of lymphocyte subsets in peripheral blood (T, B and NK cells) and the proportion of T lymphocyte (native CD4+ T cell, memory CD4+ T cell, CD8+CD28+ T cell, CD8+CDDR+ T cells and CD8+CD38+ T cell) were measured by flow cytometry.

Results

The absolute values of CD3+ T cell (972.55±330.31 vs 1757.99±439.38), CD4+ T cell (656.43±252.39 vs 899.30±262.10), and CD8+ T cell (301.97±147.76 vs 728.45±230.34) in patients with benign prostatic hyperplasia were significantly reduced (all P<0.05). There was no significant difference in NK cell (285.58±182.84 vs 528.92±208.17) and B cell (186.66±86.62 vs 334.17±130.46). The proportion of naive CD4+ T cell (3.75±0.50 vs 8.54±1.61) in T lymphocyte subsets in patients with BPH was significantly reduced (P<0.05). There was no significant difference in memory CD4+ T cell (87.9±6.37 vs 92.63±5.94), CD8+CD28+ T cell (60.52±13.86 vs 64.32±12.78), CD8+CDDR+ T cell (36.58±12.87 vs 31.92±8.54) and CD8+CD38+ T cell (2.1±1.90 vs 2.55±2.01).

Conclusion

Immune dysfunction raised the risk of viral infection, inflammatory stimulation, and tumor induction in prostate cells, leading to hyperplasia, and immune non-response was potentially a key factor in the transformation of BPH into prostate cancer.

Ethics Approval

The study protocols were conducted according to the principles of the Declaration of Helsinki and were approved by the Scientific and Medical Ethical Committee of the Second Affiliated Hospital of Shantou University Medical College.
