Abstract:
OBJECTIVE:To explore the expression of CD40/CD40L in multiple myeloma(MM) patients and its influence on prognosis.
METHODS:Thirty patients with MM treated in Cangzhou People's Hospital from May 2016 to June 2017 were selected and divided into MM group, then 30 healthy people with a physical examination in our hospital at the same time were selected as the normal group. The serum CD40/CD40L levels of the patients in the two groups was detected by flow cytometry, and its correlation with the lymphocyte population, pathological grade and prognostic significance of MM patients was anaysis.
RESULTS:The expression of CD40 in serum of the patients in MM group was significantly higher than those in normal group (P<0.05). The expression of CD40L in serum of the patients in MM group showed no significant difference as compared with those in normal group (P>0.05). The levels of CD40 and CD40L in the patients before and after chemotherapy showed no difference(P>0.05). The levels of Ts and NK cells in the patients of MM group were lower than those in normal group (P<0.05). The proportion of total B lymphocytes, Th and Th/Ts cells between the two groups showed no significant difference (P>0.05). The CD40 level was correlated with the serum total B lymphocyte level of the patients in MM group (r=0.877, P=0.005). There was a correlation with CD40L and Th cells in the serum of MM patients (r=-0.783, P=0.035). The expression of serum CD40 in the patients at phase III-IV was higher than those of the patients at phase I-II, the levels of serum CD40L in MM patients at different periods showed no significant difference(P>0.05). The survival rate of MM patients with high CD40 expression was lower than that of MM patients with low CD40 expression (χ
CONCLUSION:The increasing of CD40 level in MM patients is related to the pathological grade of the patients. Chemotherapy can reduce the level of CD40. The increasing of CD40 is an important factor for the poor prognosis of MM patients. CD40L level is not meaningful for MM treatment and prognosis.
