[Evaluation of the Efficacy of Cyclosporin A Combined with Recombined Human Erythropoietin in the Treatment of Patients with Chronic Aplastic Anemia].

Objective To compare the efficacy and safety of cyclosporin A(CsA)and CsA combined with recombined human erythropoietin(rhEPO)in the treatment of patients with chronic aplastic anemia(CAA).Methods Data of 79 patients with CAA treated at Department of Hematology,PUMC Hospital between January 2016 and June 2018 were collected for retrospective analysis.Forty-five patients were treated with CsA+rhEPO,and the other 34 patients with CsA alone.All the enrolled patients were treated for at least 1.5-2.0 years and followed for at least 1.0 year.The efficacy,side effects,long-term outcomes were compared between the two groups,and factors that may influence the efficacy were analyzed.Results The patients treated with CsA+rhEPO included 14 males and 31 females,with a median age of 43(19,73)years old.The median treatment duration of CsA and rhEPO was 26(12,38)and 4(3,6)months,respectively,and the median followed-up time was 24(12,42)months.The patients treated with CsA alone included 16 males and 18 females,with a median age of 36(16,85)years old.The median CsA treatment duration was 24(12,40)months and the median follow-up time was 25(12,40)months.There was no statistical difference in baseline characteristics between the two groups(all P>0.05).After 6 months of treatment,CsA+rhEPO group had higher overall response(OR)rate(55.6% vs. 31.3%;χ 2=4.456,P=0.040)and partial response(PR)rate(53.3% vs. 25.0%;χ2=6.181,P=0.019)than CsA group,and the complete response(CR)rate showed no statistical difference between the two groups(2.2% vs. 6.3%;χ2=0.810,P=0.567).The CR,PR,and OR rates showed no statistical difference between the two groups after 3 and 12 months of treatment and at the end of follow-up(all P>0.05).Similarly,the hemoglobin level at the sixth month of treatment with CsA+rhEPO was higher than that with CsA alone [(102.6±24.0)g/L vs.(90.3±29.1)g/L;t=2.017,P=0.047].However,it showed no significant difference between the two groups at other time points(all P>0.05).The side effects,including an increase in serum creatinine,slight increase in bilirubin,increase in aminotransferase,mild to moderate gingival hyperplasia,gastrointestinal reaction,and muscular fibrillation,had no significant differences between the two groups(all P>0.05),except that 11.1%(5/45)patients in the CsA+rhEPO group reported soreness at the injection site.The two groups showed similar rates of clonal revolution during the follow-up period and no death.No clinical factor was found for prediction of the efficacy of CsA+rhEPO. Conclusion CsA+rhEPO has higher OR rate and hemoglobin level than CsA alone at the sixth month of treatment,and it has similar side effects compared with CsA alone.

Treatment of Chronic Aplastic Anemia with Chinese Patent Medicine Pai-Neng-Da Capsule () for Replacing Androgen Partially: A Clinical Multi-Center Study.

OBJECTIVE: To evaluate the efficacy and safety of Pai-Neng-Da Capsule (, panaxadiol saponins component, PNDC) in combination with the cyclosporine and androgen for patients with chronic aplastic anemia (CAA). METHODS: A total of 79 CAA patients was randomly divided into 2 groups by a random number table, including PCA group [43 cases, orally PNDC 320 mg/d plus cyclosporine 5 mg/(kg·d) plus andriol 80 mg/d] and CA group [36 cases, orally cyclosporine 5 mg/(kg·d) plus andriol 160 mg/d]. All patients were treated and followed-up for 6 treatment courses over 24 weeks. The complete blood counts, score of Chinese medical (CM) symptoms were assessed and urine routine, electrocardiogram, hepatic and renal function were observed for safety evaluation. Female masculinization rating scale was established according to the actual clinical manifestations to evaluate the accurate degree of masculinization in female CAA patients treated by andriol. RESULTS: The effective rates were 88.1% (37/42) in the PCA group and 77.8% (28/36) in the CA group based on the standard for the therapeutic efficacy evaluation of hematopathy. There was no significant difference in the white blood cell (WBC) counts, platelet counts and hemoglobin concentration of peripheral blood between two groups after 6 months treatment. The masculinization score of female patient in the PCA group was significantly lower than the CA group (P<0.05). The mild abdominal distention was observed in 1 cases in the PCA group. In CA group, the abnormalities in the hepatic function developed in 2 cases and the renal disfunction was found in 1 case. CONCLUSION: The PNDC possesses certain curative effects in the treatment of CAA without obvious side-effects and can partially replace andriol thereby to reduce the degree of masculinization [Registried at Chinese Clinical Trial Registry (ChicTR1900028153)].

Clinical study of pai-neng-da capsule in the treatment of chronic aplastic anemia.

OBJECTIVE: To evaluate the efficacy and safety of Pai-Neng-Da Capsule (panaxadiol saponins component, PND), a new Chinese patent medicine, on patients with chronic aplastic anemia (CAA) and to explore the optimal therapeutic regimen for CAA. METHOD: A total of 36 patients with CAA were enrolled and divided into three groups: the AP group (20 cases, andriol 120 mg/day + PND 240 mg/day), the ACP group (13 cases, andriol 120 mg/day + cyclosporine 3-6 mg kd(-1) day(-1) + PND 240 mg/day), and the PND group (3 cases, PND 240 mg/day). All patients were treated and followed up for 6 months. Peripheral blood counts, renal and hepatic function and Chinese medical (CM) symptoms of patients were assessed and all indices were gathered at the beginning and end of the study. RESULT: In the AP group, no significant hematologic difference was observed at the end of 6-month treatment comparing with the beginning. In the ACP group, the blood counts were maintained at the same level after the 6-month treatment. In the PND group, trilineage hematologic improvement was displayed at the end of 6-month treatment comparing with the beginning. No significant difference was showed in renal and hepatic function in all patients. All patients' clinical symptom improved according to CM symptom score. The effective rates were 95%, 73% and 100%, respectively. CONCLUSION: PND improved the efficacy and decreased side effects by cutting down the dosage of andriol, and it could also improve patients' clinical symptom and quality of life. PND were effective and safe in the treatment of CAA, it could be used alone or in combination with pharmacological agents such as andriol and cyclosporine.

Role of heteroplasmic mutations in the mitochondrial genome and the ID4 gene promoter methylation region in the pathogenesis of chronic aplastic anemia in patients suffering from Kidney yin deficiency.

OBJECTIVE: To analyze changes in gene amplification in the mitochondrial genome and in the ID4 gene promoter methylation region in patients with chronic aplastic anemia (CAA) suffering from Kidney (Shen) yin deficiency or Kidney yang deficiency. METHODS: Bone marrow and oral epithelium samples were collected from CAA patients with Kidney yin deficiency or Kidney yang deficiency (20 cases). Bone marrow samples were collected from 20 healthy volunteers. The mitochondrial genome was amplified by polymerase chain reaction (PCR), and PCR products were used for sequencing and analysis. RESULTS: Higher mutational rates were observed in the ND1-2, ND4-6, and CYTB genes in CAA patients suffering from Kidney yin deficiency. Moreover, the ID4 gene was unmethylated in bone marrow samples from healthy individuals, but was methylated in some CAA patients suffering from Kidney yin deficiency (positive rate, 60%) and Kidney yang deficiency (positive rate, 55%). CONCLUSIONS: These data supported that gene mutations can alter the expression of respiratory chain enzyme complexes in CAA patients, resulting in energy metabolism impairment and promoting the physiological and pathological processes of hematopoietic failure. Functional impairment of the mitochondrial respiration chain induced by gene mutation may be an important reason for hematopoietic failure in patients with CAA. This change is closely related to maternal inheritance and Kidney yin deficiency. Finally, these data supported the assertion that it is easy to treat disease in patients suffering from yang deficiency and difficult to treat disease in patients suffering from yin deficiency.
