OBJECTIVE: To investigate the clinical efficacy of calcitriol combined with sirolimus in the treatment of chronic primary immune thrombocytopenia (cITP) patients. METHODS: A total of 146 adult cITP patients reated in the First Affiliated Hospital of Hebei North University from March 2017 to March 2020 were randomly divided into observation group (73 cases) and control group (73 cases) according to random number table. The control group was treated with oral sirolimus capsule, the observation group was treated with oral calcitriol capsule combined with sirolimus capsule, and the curative effect of the 2 groups was evaluated after continuous treatment for 6 weeks. The changes of World Health Organization (WHO) bleeding grade, laboratory related index, including peripheral blood regulatory T cell (Treg), serum 1,25-dihydroxy-vitamin D RESULTS: The total effective rate of the observation group was 79.5% (58/73), which was significantly higher than 64.4% (47/73) of the control group (P<0.05). The revised WHO bleeding grades after treatment were significantly better than those before treatment in the 2 groups (P<0.05), but the observation group was improved more significantly than the control group (P<0.05). After treatment, platelet count (PLT), peripheral blood Treg cell ratio, and serum 1,25(OH) CONCLUSION The overall efficacy of calcitriol combined with sirolimus in the treatment of cITP in adults is satisfactory, which can effectively alleviate patient's condition, improve the quality of life, further increase the platelet level and decrease the expression of VDR in peripheral blood lymphocyte, the mechanism may be related to increasing the level of serum 1,25(OH)

Kaposi sarcoma (KS) has attracted much attention recently because of its high incidence among patients with acquired immune deficiency syndrome. Other groups with a high risk of developing KS are renal transplant recipients treated with immunosuppressive drugs and, to a lesser extent, patients with autoimmune diseases. We report the case of a patient who developed KS during corticosteroid therapy for idiopathic thrombocytopenic purpura, which subsequently regressed with combination chemotherapy.

OBJECTIVE: To investigatc the curative efficacy of low dose rituximab for glucocorticoid ineffective on dependent ITP patients and its relation with sensitivity to glucocorticoid so as to provide reference basis for rational use of drugs in clinical treatmant. METHODS: Seventy-ninth ITP patients enrolled in this study included the glucocorticoid-ineffective patients (19 cases) and glucocorticoid-dependent patients (60 cases). All ITP patients were treated with regimen consisted of high dose dexamethasone plus low dose rituximab (dexal-methasone 40 mg/d for 4 days per os, ritaximab 100 mg by intravenous infusion at D7, 14, 21 and 28 respectively). The patients after treatment were followed-up for 12 month, and the relation of patients sensitivity to glucocorticoid with therapentic response of rituximab was analyzed. The changes of Treg cell ratio and BAFF, IL-2 and sCD40L levels before and after treatment were detected by flow cytometry and ELISA respectively. RESULTS: The overall response rate (ORR) of patients treated with above- mentioned regemen at 1, 3, 6 and 12 months after treatment was 79.7% (63/79), 69.6% (55/79), 63.3% (50/79) and 60.8% (48/79) respectivcly, out of which the ORR of glucocorticoid ineffective and glucocorticoid-dependent ITP patients treated with above-mentioned regimen at 1, 3, 6 and 12 months after treatment was 47.4% (9/19) vs 90.0% (54/60), 36.8% (7/19) vs 80.0% (48/60), 21.1% (4/19) vs 76.7% (46/60), 21.1% (4/19) vs 73.3% (44/60), and the difference between 2 groups was statistically significant. The detection of T reg cell showed that the T reg cell ratio in glucocorticoid- ineffective and dependent patients at 1, 3, 6 and 12 months after treatment was (1.70±0.43)% vs (3.47±0.72)%, (1.66±0.33)% vs (4.29±0.91)%, (1.71±0.37)% vs (4.44±0.97)%, (3.36±0.54)% vs (4.29±1.04)%, respectively. The detection of cytokines showed that the levels of BAFF, IL-2 and sCD40L in plasma of glucocorticoid-dependent patients at 1 month after treatment significanlly decreased (P＜0.05), the levels of BAFF, IL-2 and sCD40L in plasma of glucocorticoid-ineffective patients although decreased at 1 mouth after treatment, but there was no statistical difference as compared with glucocosticoid-depenment patients. CONCLUSION The treatment of glucocorticoid-dependent ITP patients with rituximab is more effective. The regulatory effect of rituximab on the T-reg cells, BAFF, IL-2 and sCD40L may be one of its mechanisms.

OBJECTIVE: To compare the effect of Sheng-Xue-Xiao-Ban Capsule (SXXBC) and indirubin to the peripheral platelets of the Idiopathic thrombocytopenic purpura (ITP) model mouse. METHODS: The ITP mouse model was established by the method of passive immunization. SXXBC and indirubin were used for intervention treatment. Then the hemorrhagic phenomena of ITP mice were observed and the numbers of peripheral platelets, hemoglobin and white blood cells, bone marrow megakaryocytes and their classification and coagulation function were detected and compared. RESULTS: The improvement rate of hemorrhage in SXXBC group was 40% for small dose, 60% for medium dose and 80% for high dose, while the improvement rate of hemorrhage in indirubin group was 30% for small dose, 50% for medium dose and 60% for high dose. There was no statistically significant difference in the improvement rate of hemorrhage between the two groups (P＞0.05). Compared with the model control group, PLT and Hb increased in different doses of SXXBC and indirubin group 4th-8th day after drug intervention (P＜0.05, 0.01). However, there was no significant difference between the different doses of SXXBC group and indirubin group (P＞0.05). Compared with the model control group, the WBC in each group was significantly lower (P＜0.05, 0.01) on the 4th-8th day after drug intervention; However, there was no statistical significance between the two groups of SXXBC and indirubin (P＞0.05). Compared with the model control group, the total number of megakaryocytes in each treatment group were decreased (P＜0.05, P＜0.01), in which the number of primary megakaryocytes in the large and medium dose groups of SXXBC and indirubin were decreased (P＜0.05, 0.01), and the number of juvenile megakaryocytes in the large dose group of SXXBC and indirubin were also decreased (P＜0.05). The number of granular megakaryocytes were decreased in each intervention groups (P＜0.05, 0.01), and the number of thromocytogenic megakaryocyte was increased in the high and medium dose groups of SXXBC and indirubin (P＜0.01). The time of prothrombin was shortened in the high and medium dose groups of SXXBC and indirubin (P＜0.05), and the fibrinogen (FIB) content in the high and medium dose groups of SXXBC was close to that of the normal control group. CONCLUSION Both of the SXXBC and the indirubin standard all show good hemostatic effects. Indirubin shows a positive effect on increasing the peripheral platelet and hemoglobin in ITP model mice, regulating the immune response, reducing the total number of bone marrow megakaryocytes, increasing the thromocytogenic megakaryocyte, and increasing coagulation function.

Primary immune thrombocytopenia (ITP) is a blood system disease mediated by autoimmune mechanism. Currently, the goal of treatment for primary ITP is to keep patients' peripheral platelet count at a safe level to prevent severe bleeding. Recently, avatrombopag and fostamatinib have been approved by the FDA for the treatment of primary ITP in adults, while new drugs such as rozanolixizumab, efgartigimod, PRTX-100, decitabine and atorvastatin have shown efficacy in early clinical trials. This review summarizes the current accepted therapies for the clinical treatment of primary ITP in adults, and briefly discuss the progress of new therapies.

Objective: To observe the efficacy and adverse reactions of a combination therapy regimen based on bortezomib and glucocorticoids in recurrent/refractory immune thrombocytopenic purpura (iTTP) . Methods: Six patients with recurrent/refractory TTP were included and treated with a glucocorticoid and two courses of bortezomib-based regimen. The clinical remission status of patients, changes in ADAMTS13 activity/ADAMTS13 inhibitor, and the occurrence of treatment-related adverse reactions were observed. Results: Of the 6 patients, 2 were males and 4 were females, with a median age of 21.5 (18-68) years. Refractory TTP was found in 1 case and recurrent TTP in 5 cases. Glucocorticoids were administered with reference to prednisone at 1 mg·kg(-1)·d(-1), and gradually reduced in dosage after achieving clinical remission. Bortezomib is subcutaneously administered at 1.3 mg/m(2) on days 1, 4, 8, and 11 with a 28-day treatment course consisting of 2 courses. Six patients achieved clinical remission after receiving bortezomib as the main treatment. ADMATS13 activity returned to normal in all patients with TTP after treatment, and the ADAMTS13 inhibitor turned negative. Thrombocytopenia is the most common adverse reaction after treatment, with other adverse reactions, including peripheral neuritis and abdominal pain, but ultimately all patients returned to normal. In a median follow-up of 26 (9-41) months, 5 patients maintained sustained remission, and 1 patient relapsed after 16 months of bortezomib treatment. Conclusion: Combination therapy of bortezomib and glucocorticoids has a satisfactory therapeutic effect and controllable adverse reactions for recurrent/refractory iTTP.
