BACKGROUND: Recombinant human thrombopoietin (rh-TPO) and eltrombopag are two distinct TPO receptor agonists (TPO-RAs) with different mechanisms. During the pandemic, when immunosuppressive medications are controversial, switching to another TPO-RA may be worth exploring in patients who do not benefit from their first TPO-RA. We investigated the outcomes of switching from rh-TPO to eltrombopag or vice versa in immune thrombocytopenia (ITP) patients. METHODS: This prospective, open-label, observational investigation included 96 adult ITP patients who needed to switch between rh-TPO and eltrombopag between January 2020 and January 2021 at Peking University People's Hospital in China. The study evaluated response rates and platelet counts at different time points after the switch, bleeding events, time to response, duration of response, and adverse events. RESULTS: At 6 weeks after switching, response was observed in 21/49 patients (43%) who switched for inefficacy and 34/47 patients (72%) who switched for non-efficacy-related issues. In the inefficacy group, 9/27 patients (33%) responded to eltrombopag, and 12/22 patients (55%) responded to rh-TPO. In the non-efficacy-related group, 21/26 (81%) and 13/21 (62%) patients in the eltrombopag and rh-TPO groups maintained their response rates at 6 weeks after switching, respectively. Response at 6 months was achieved in 24/49 patients (49%) switching for inefficacy and 37/47 patients (79%) switching for non-efficacy issues. In the inefficacy group, 13/27 patients (48%) responded to eltrombopag, and 11/22 patients (50%) responded to rh-TPO. In the non-efficacy-related group, 22/26 patients (85%) and 15/21 patients (71%) in the eltrombopag and rh-TPO groups maintained their response rates at 6 months after switching, respectively. Both eltrombopag and rh-TPO were well tolerated. CONCLUSIONS: Our study confirmed the safety and effectiveness of switching between rh-TPO and eltrombopag for ITP patients who had no response to or experienced adverse events with their first TPO-RA. When the switch was motivated by other reasons, including patient preference and platelet count fluctuations, the probability of response was high. REGISTRATION ClinicalTrials.gov, NCT04214951.

OBJECTIVE: To investigate the effect of recombinant human granulocyte colony stimulating factor (rhG-CSF) on the clinical efficacy and flow cytometry (FCM) minimal residual disease (MRD) of patients with acute myeloid leukemia (AML) after initial induction therapy in the real world. METHODS: The clinical data of 44 AML patients who were diagnosed for the first time in the Department of Hematology, The Second Hospital of Anhui Medical University, and received the initial induction therapy were retrospectively analyzed. According to whether rhG-CSF was used after treatment, these patients were divided into control group and therapy group. The complete remission (CR) rate, duration of neutropenia, incidence of infection, duration of fever, cost of antibiotics drugs, length of hospital stay, FCM MRD, and relapse-free survival (RFS) time were compared between the two groups. RESULTS: The CR rate in the control group was 60%, and 74% in the therapy group (P=0.3429). The duration of neutropenia was (21.28±7.91) days in the control group and (14.79±3.07) days in the therapy group (P=0.0016). The duration of fever was (12.80±7.31) days in the control group and (9.11±7.48) days in the therapy group (P=0.0136). While, there were no statistically significant differences between the two groups in the incidence of infection, cost of antibacterial drugs, length of hospital stay and RFS time (all P>0.05). In addition, it is particularly noteworthy that among the patients who finally obtained CR in the therapy group, 66% of them had myeloid precursor cells detected by peripheral blood FCM (accounting for 2.25%±0.99%) at the time of the first release of neutropenia, which was easy to be misdiagnosed as MRD positive. CONCLUSION rhG-CSF not only don't affect the clinical remission rate after the initial induction treatment of AML, but also significantly shortens the time of duration of neutropenia and fever, however, it may affect the analysis of peripheral blood FCM MRD detection results when the neutropenia is released for the first time.

OBJECTIVES: To observe the efficacy and adverse reactions of the combination of endostar with chemotherapy in the treatment of advanced (IVb) and recurrent metastatic cervical cancer. METHODS: Forty-four patients with recurrent and metastatic cervical cancer, who were admitted to the Second Xiangya Hospital, Central South University from December 2016 to December 2018 were randomly divided into an experimental group and a control group (22 cases in each group). The control group was given gemcitabine plus cisplatin (GP) or docetaxel plus cisplatin (DP) treatment, the experimental group was treated with endostar on the basis of the control group. RESULTS: The objective response rate (ORR) was 42.9% in the experimental group and 22.7% in the control group. There was no significant difference between the 2 groups ( CONCLUSIONS Compared with chemotherapy alone, endostar combined with chemotherapy can prolong the median progression-free survival, with higher ORR and similar adverse reactions.

Objective: To compare the time of the recovery of neutrophils or leukocytes by pegylated recombinant human granulocyte stimulating factor (PEG-rhG-CSF) or common recombinant human granulocyte stimulating factor (rhG-CSF) in the myelosuppressive phase after induction chemotherapy in newly diagnosed acute myeloid leukemia (AML) patients. At the same time, the incidences of infection and hospitalization were compared. Methods: A prospective randomized controlled trial was conducted in patients with newly diagnosed AML who met the enrollment criteria from August 2014 to December 2017. The patients were randomly divided into two groups according to a 1:1 ratio: PEG-rhG-CSF group and rhG-CSF group. The time of neutrophil or leukocyte recovery, infection rate and hospitalization interval were compared between the two groups. Results: 60 patients with newly diagnosed AML were enrolled: 30 patients in the PEG-rhG-CSF group and 30 patients in the rhG-CSF group. There were no significant differences in age, chemotherapy regimen, pre-chemotherapy ANC, WBC, and induction efficacy between the two groups (P>0.05) . The median time (range) of ANC or WBC recovery in patients with PEG-rhG-CSF and rhG-CSF were 19 (14-35) d and 19 (15-26) d, respectively, with no statistical difference (P=0.566) . The incidences of infection in the PEG-rhG-CSF group and the rhG-CSF group were 90.0%and 93.3%, respectively, and there was no statistical difference (P=1.000) . The median days of hospitalization (range) was 20.5 (17-49) days and 21 (19-43) days, respectively, with no statistical difference (P=0.530) . Conclusions: In AML patients after induction therapy, there was no significant difference between the application of PEG-rhG-CSF and daily rhG-CSF in ANC or WBC recovery time, infection incidence and hospitalization time.

Chronic hepatitis C virus (HCV) infection is a major cause of liver cirrhosis and hepatocellular carcinoma. Combination therapy of pegylated interferon-alpha (PEG-IFN-α) and ribavirin (RBV) is a current standard treatment for chronic HCV infection in Korea, which has considerable adverse effects. Acute pancreatitis is a rare complication of PEG-IFN-α administration. We report a case of a 62-year-old female who experienced acute pancreatitis after 4 weeks of PEG-IFN-α-2a and RBV combination therapy for chronic HCV infection. The main cause of the acute pancreatitis in this case was probably PEG-IFN-α rather than RBV for several reasons. A few cases have been reported in which acute pancreatitis occurred during treatment with PEG-IFN-α-2b. This is the first report of acute pancreatitis associated with PEG-IFN-α-2a in Korea.

OBJECTIVETo explore the safety and efficacy of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in preventing chemotherapy-induced neutropenia in patients with breast cancer and non-small cell lung cancer (NSCLC), and to provide the basis for clinical application.

METHODSAccording to the principle of open-label, randomized, parallel-group controlled clinical trial, all patients were randomized by 1∶1∶1 into three groups to receive PEG-rhG-CSF 100 μg/kg, PEG-rhG-CSF 6 mg, or rhG-CSF 5 μg/kg, respectively. The patients with breast cancer received two chemotherapy cycles, and the NSCLC patients received 1-2 cycles of chemotherapy according to their condition. All patients were treated with the combination chemotherapy of TAC (docetaxel+ epirubicin+ cyclophosphamide) or TA (docetaxel+ epirubicin), or the chemotherapy of docetaxel combined with carboplatin, with a 21 day cycle.

RESULTSThe duration of grade 3-4 neutropenia in the PEG-rhG-CSF 100 μg/kg and PEG-rhG-CSF 6 mg groups were similar with that in the rhG-CSF 5 μg/kg group (P>0.05 for all). The incidence rate of grade 3-4 neutropenia in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group, and G-CSF 5 μg/kg group were 69.7%, 68.4%, and 69.5%, respectively, with a non-significant difference among the three groups (P=0.963). The incidence rate of febrile neutropenia in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group and G-CSF 5 μg/kg group were 6.1%, 6.4%, and 5.5%, respectively, showing no significant difference among them (P=0.935). The incidence rate of adverse events in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group and G-CSF 5 μg / kg group were 6.7%, 4.1%, and 5.5%, respectively, showing a non-significant difference among them (P=0.581).

CONCLUSIONSIn patients with breast cancer and non-small cell lung cancer (NSCLC) undergoing TAC/TA chemotherapy, a single 100 μg/kg injection or a single fixed 6 mg dose of PEG-rhG-CSF at 48 hours after chemotherapy show definite therapeutic effect with a low incidence of adverse events and mild adverse reactions. Compared with the continuous daily injection of rhG-CSF 5 μg/kg/d, a single 100 μg/kg injection or a single fixed 6 mg dose of PEG-rhG-CSF has similar effect and is more advantageous in preventing chemotherapy-induced neutropenia.

BACKGROUND/AIMS: The relationship between patient survival and biopsy-proven acute rejection (BPAR) in liver transplant recipients with hepatitis C remains unclear. The aims of this study were to compare the characteristics of patients with and without BPAR and to identify risk factors for BPAR. METHODS: We retrospectively reviewed the records of 169 HCV-RNA-positive patients who underwent LT at three centers. RESULTS: BPAR occurred in 39 (23.1%) of the HCV-RNA-positive recipients after LT. The 1-, 3-, and 5-year survival rates were 92.1%, 90.3%, and 88.5%, respectively, in patients without BPAR, and 75.7%, 63.4%, and 58.9% in patients with BPAR (P<0.001). Multivariate analyses showed that BPAR was associated with the non-use of basiliximab and tacrolimus and the use of cyclosporin in LT recipients with HCV RNA-positive. CONCLUSION: The results of the present study suggest that the immunosuppression status of HCV-RNA-positive LT recipients should be carefully determined in order to prevent BPAR and to improve patient survival.

PURPOSE: Beroctocog alfa is a second generation recombinant factor VIII manufactured by removing the B-domain from factor VIII. This prospective clinical trial was conducted to evaluate the efficacy, safety, and pharmacokinetics of beroctocog alfa in patients of ages > or =12 years previously treated for severe hemophilia A. MATERIALS AND METHODS: Seventy subjects received beroctocog alfa as an on-demand treatment for acute hemorrhage. RESULTS: The final hemostatic effect was excellent in 35 subjects (50%) and good in 26 subjects (37.1%). The drug showed an overall efficacy rate of 87.1%. The majority of acute hemorrhages was treated by administering the study drug once (86.2%) or twice (10.0%), and the mean dose administered per single infusion was 28.55+/-6.53 IU/kg. Ten subjects underwent 12 surgical procedures, and hemostatic efficacy was excellent in seven cases (58.3%) and good in five cases (41.7%), showing a 100% efficacy rate. A total of 52 of 88 subjects (59.0%) experienced 168 adverse events. There were 18 serious adverse events (10.7%) in 11 subjects, and two (mild dyspnea and facial edema) in one subject were related to the study drug. Only one subject formed a de novo factor VIII inhibitor, for an occurrence rate of 1.4% (one-sided 95% upper confidence limit: 3.85%). The final elimination half-life was 13.3 h and 12.6 h at baseline and 6 months after administration, respectively. CONCLUSION: Our results suggest that beroctocog alfa is safe and efficacious as either an on-demand treatment for acute hemorrhage or a surgical prophylaxis in patients with hemophilia A.

BACKGROUND/AIMS: Chronic hepatitis C (CHC) is a major comorbidity in patients with hemophilia. However, there are no published data on the efficacy of antiviral therapy in Korea. We assessed the safety and efficacy of combination therapy with peginterferon alpha-2a plus ribavirin for CHC in hemophilia. METHODS: Patients (n=115) were enrolled between March 2007 and December 2008. Seventy-seven patients were genotype 1 or 6, and 38 patients were genotype 2 or 3. We evaluated rapid virologic responses (RVRs), early virologic response (EVRs), end-of-treatment response (ETRs), sustained virologic response (SVRs), and relapses. Safety evaluations included adverse events and laboratory tests. RESULTS: Eleven patients were excluded from the study because they had been treated previously. Among the remaining 104 treatment-naive patients, RVR was achieved in 64 (60.6%), ETR was achieved in 95 (91.3%), and SVR was achieved in 89 (85.6%). Relapse occurred in eight patients (8.9%). Common adverse events were hair loss (56.7%) and headache (51.0%). Common hematologic adverse events were neutropenia (22.1%), anemia (27.9%), and thrombocytopenia (3.8%). However, there were no serious adverse events such as bleeding. RVR was the only predictor of SVR in multivariate analysis. CONCLUSIONS: Peginterferon alpha-2a plus ribavirin combination treatment produced a favorable response rate in CHC patients with hemophilia without serious adverse events.

OBJECTIVETo evaluate the clinical efficacy of Yiqi Jianpi Recipe (YJR) in treating cancer-related fatigue (CRF) after chemotherapy in lung cancer patients. Methods Totally 124 lung cancer patients were assigned to the treatment group (63 cases) and the control group (61 cases) according to random digit table. All patients received pre-set chemotherapy regimens according their conditions. Patients in the treatment group took YJR Decoction from the 1st day of chemotherapy, one dose per day for 2 successive weeks, while those in the control group took no Chinese medical decoction. Changes of each dimensional scoring and the total scoring were observed by cancer fatigue scale (CFS) in the two groups one day before chemotherapy, on the 3rd day and the 14th day after chemotherapy. The degree of bone marrow depression and recombinant human granulocyte colony-stimulating factor (rhG-CFS) doses were also observed after chemotherapy.

RESULTSCompared with one day before chemotherapy in the same group, scorings for emotional, perceptional, and somatologic dimensions, and the total scoring significantly increased on the 3rd day in the treatment group, as well as on the 3rd and the 14th day in the control group (P <0. 01). Scorings for emotional, perceptional, and somatologic dimensions, and the total scoring significantly decreased more at the fourteenth day after chemotherapy than at the 3rd day after chemotherapy (P <0. 01). There was statistical difference in the scoring for perceptional dimension at day 3 between the treatment group and the control group (P <0.01). However, scorings for emotional, perceptional, and somatologic dimensions, and the total scoring significantly decreased more at the fourteenth day after chemotherapy in the treatment group, with statistical difference when compared with those in the control group (P <0. 01). The occurrence rate of bone marrow depression was 70. 97% (44/62) in the treatment group and 68. 85% (42/61) in the control group. There was no significant difference in the occurrence rate between the two groups (χ2=0. 540, P >0.05). There was no statistical difference in rhG-CFS doses between the two groups (χ2=0. 696, P >0. 05).

CONCLUSIONYJD could significantly relieve CRF after chemotherapy in lung cancer patients, and obviously attenuate the effect of CRF on their daily life.
