ABSTRACT
Objective:To investigate the role of short-term use of mycophenolate mofetil (MMF) in EB viral infection and acute graft-versus host disease (GVHD) in patients receiving haploidentical hematopoietic stem cell transplantation (haplo-HSCT) .Method:Adult patients (≥14 years) who were diagnosed with hematological malignancies received haplo-HSCT in Peking University Institute of Hematology from May 2016 to December 2017 were retrospectively reviewed. The median age was 30 (14-60) years old. A total of 498 patients including 277 males and 221 females were enrolled. Donors' median age was 38 (8-66) years old. All patients were classified into long-term use of MMF ( n=199), which was defined as 500 mg every 12 hours from day 9 pre-transplant to 250 mg every 12 hours from day 30 after transplant then withdrawal on day 45 to 60 after transplant, and short-term use of MMF ( n=299), which was defined as 500 mg every 12 hour from day 9 pre-transplant then withdrawal till neutrophil engraftment. Kaplan-Meier model was used to analyze the cumulative incidence of EBV infection, and the Cox proportional regression model for multivariate analysis. Result:Characteristics including sex, age, disease types, mismatched HLA loci, donor-recipient relationship, donor-recipient blood type, donor age, and donor sex were comparable between two groups (all P＞0.05). According to once, the incidence of EBV viremia, defined as EBV＞10 3 copies/ml at least once, in short-term group and long-term group was 19.4% (58/299) and 27.6% (55/199) respectively ( P=0.046).Donor age and the duration of MMF prophylaxis (short-term group as reference) were associated with EBV viremia according to multivariate analysis [ HR=1.022(95% CI 1.006-1.038),1.600(95% CI 1.059-2.418); P=0.006 and 0.026, respectively]. The incidence of grade Ⅱ-Ⅳ and Ⅲ/Ⅳ acute GVHD in long-term and short-term group was 32.2% (64/199) versus 20.7% (62/299)( P=0.005) and 10.1% (20/199) versus 8.0% (24/299) ( P=0.427), respectively. Donor sex (female as reference) and duration of MMF prophylaxis (short-term group as reference) were associated with grade Ⅱ-Ⅳ acute GVHD [ HR=1.908(95% CI 1.079-3.373),1.752(95% CI 1.161-2.643); P=0.026 and 0.008, respectively].There were no statistical differences in the incidence of CMV viremia, refractory CMV viremia and hemorrhagic cystitis (all P＞0.05) between the two groups. Conclusion:Short-term use of MMF can reduce EBV viremia without increasing the development of acute GVHD in haplo-HSCT patients.
ABSTRACT
Objective To observe the effects of compound Sophorae Flavescentis Radix (Kushen) Injection on immune function and quality of life in ovarian cancer patients with chemotherapy. Methods Sixty cases of ovarian cancer patients with chemotherapy were randomly divided into the observation group and the control group. Patients in the observation group were treated with paclitaxel plus carboplatin chemotherapy plus compoundKushen Injection for intravenous injection, while the patients in the control group were treated with paclitaxel plus carboplatin chemotherapy for three cycles. Changes in peripheral venous blood, the level of T cell subsets and NK cell, body weight, quality of life of 1 day before chemotherapy and 1 week after chemotherapy were observed.Results The mean values of CD3+, CD4+, CD4+/CD8+ and NK cells in the observation group improved to certain different degrees, with statistical significance compared with the control group (P0.05). Karnofsky score of the observation group increased after chemotherapy (P0.05).Conclusion CompoundKushen Injection can effectively enhance the immune function of ovarian cancer patients with chemotherapy, increase the weight of patients, and improve their quality of life.
