ABSTRACT

The over-activation of phosphatidylinositol 3-kinase (PI3K) signaling pathway is closely related to the occurrence and development of malignant tumors. The abnormal expression of this pathway is involved in the regulation of cell growth, malignant transformation, apoptosis and metastasis. The targeted therapy for specific sites of PI3K signaling pathway is a new research hotspot. A variety of different types of PI3K inhibitors have been marketed or entered clinical trials and have shown considerable efficacy in the treatment of malignant lymphomas. In this view, the recent advances in activation patterns of PI3K signaling pathway in lymphoma and PI3K inhibitors are summarized.

ABSTRACT

Objective Toevaluateefficacyandsafetyoftwodifferentbiologicalsinimmunologic inductiontherapyonrenaltransplantrecipients.Methods Clinicaldataof78renaltransplantrecipientswho received biological immunologic induction therapy in Department of Urology of the 452nd Hospital of Chinese People's Liberation Army from June 2008 to April 2013,were retrospectively analyzed. According to different biological immunologic induction therapy,the recipients were divided into two groups,monoclonal antibody group (group A,n=35,received treatment of basiliximab)and polyclonal antibody group [group B,n=43, received treatment of antithymocyte globulin (ATG)]. And the other recipients who didn't receive immunologic induction therapy in the hospital during the corresponding period were chosen as control group (group C,n=32). The survival rates of recipient and kidney in 3 groups at 12th weeks after transplantation were analyzed.The levels of serum creatinine (Scr)of recipients in 3 groups were monitored at 7,14,30,60 d after transplantation. The occurrence rates of complications including acute rejection,delayed graft function and infectionwerecomparedamong3groups.Results At12thweeksaftertransplantation,thesurvivalratesof recipient and kidney in 3 groups were 100% and 100% in group A,97.7% and 97.7% in group B,100%and 96.9% in group C. There was no significant difference among 3 groups (all in P>0.05 ). Compared with group C,the Scr levels in group A and B decreased significantly at 7,14 d after transplantation (all in P<0.05 ). Compared with group C,the incidence rates of acute rejection decreased in group A and B(all in P<0.05 ). There was no significant difference in the incidence rates of delayed graft function among 3 groups (all in P>0.05 ). The incidence rate of infection in group B was significantly higher than those in group A and C (allinP<0.05).Conclusions Immunologicinductiontherapyissafeandeffectiveintheapplicationon renal transplant recipients.

ABSTRACT

BACKGROUND:At present, biological agent-involved immunologic induction therapy gradual y became a key component in immunosuppression therapy of kidney transplantation. It can effectively prevent acute rejection and avoid the appearance of complications. OBJECTIVE:To evaluate the effect of different biological agents on immune state and functional status of transplanted kidney in immunologic induction therapy. METHODS:Clinical data of 110 recipients with kidney transplantation were retrospectively analyzed. In accordance with the conditions of immunologic induction therapy, recipients in the monoclonal antibody group (n=35) received basiliximab. Recipients in the polyclonal antibody group (n=43) underwent rabbit anti-human antithymocyteglobulin. Recipients in the control group (n=32) did not receive immunologic induction therapy. Absolute value of lymphocytes and the number of CD4+T lymphocyte subsets in peripheral blood were comparatively analyzed among three groups at 1, 4 and 12 weeks after kidney transplantation. Functional status of the transplanted kidney and complications of infection were evaluated at 12 weeks after transplantation.RESULTS AND CONCLUSION:The incidence of acute rejection was lower in the monoclonal antibody group and polyclonal antibody group than in the control group (P<0.05). The incidence of infectious complications was higher in the polyclonal antibody group than in the monoclonal antibody group and control group (P<0.05). The absolute value of lymphocytes was lower in the monoclonal antibody group and polyclonal antibody group at 1, 4 and 12 weeks after transplantation than in the control group (P<0.05). The number of CD4+T lymphocyte subsets in peripheral blood was lower in the polyclonal antibody group than in the monoclonal antibody group and control group at 1, 4 and 12 weeks after transplantation (P<0.05). These results suggested that biological agents participate in immunologic induction therapy of kidney transplantation, can effectively suppress the functional status of activated T lymphocytes, and decrease the occurrence of early acute rejection of the transplanted kidney. However, the incidence of infectious complications was higher after the use of rabbit anti-human antithymocyteglobulin.
