ABSTRACT

Objective:To analyze the efficacy and safety of Daratumumab for the treatment of primary AL light chain systemic amyloidosis.Methods:Twenty one patients who were diagnosed as primary AL light chain systemic amyloidosis and treated with Daratumumab from 7 centers were retrospectively analyzed. Daratumumab was administrated as first line therapy in seven patients and 14 patients with relapsed settings. Hematological response, safety and survival were analyzed.Results:All 7 patients achieved very good partial response (VGPR) or better with first-line application of daratumumab. Three patients died, and the other four achieved organ remission. Among 14 relapsed patients, 2 patients had a difference of free light chain (dFLC) less than 20 mg/L before treatment, and 9 with a dFLC of more than 50 mg/L. All patients reached partial response (PR) or better, including 4 patients with complete response (CR), 3 with VGPR and 2 with PR. The response rate was 100% in 3 patients with dFLC 20-50 mg/L at baseline. The organ remission rate was 50% in patients with heart involvement and 58.3% in patients with kidney impairment. The overall median follow-up period was 5.3 months, and 11 months in surviving patients. One patient died of severe infection and disseminated intravascular coagulation (DIC) with stable amyloidosis. One patient switched to other regimens because dFLC elevated but did not fulfill progressive disease after 2 year application. As to safety, no grade 3/4 infusion reaction developed, and grade 1 infusion reaction occurred in 3 cases during the first infusion. Lymphocytopenia was seen in 75% patients including grade 3 or more in 30% patients.Conclusion:Daratumumab is effective to eliminate serum free light chain in both newly diagnosed and relapsed patients with systemic amyloidosis.

ABSTRACT

Objective@#To investigate the association between the preterm birth and low birth weight and parental thalassemia.@*Methods@#Pregnant women and their husbands receiving prenatal examination in local hospitals or maternal and child health centers in Jingxi and Debao in Guangxi from January to December 2017 were selected as study subjects. A total of 758 pregnant women with pregnancy outcomes and their husbands, who were both or alone diagnosed with thalassemia through thalassemia gene detection, were selected as case group and 758 pregnant women with pregnancy outcomes and their husbands, who were negative in thalassemia gene detection and hemoglobin electrophoresis test were selected as control groups. The case group were further divided into mother group, father group and both mother and farther group. Clinical and pregnancy outcome data of the study subjects were collected for the analysis on the association between parental thalassaemia and preterm birth or low birth weight by the independent sample t test, χ2 test and Cox regression analysis.@*Results@#The incidence of preterm birth in case group and control group was about 6.5% and 1.6% and the incidence of low birth weight in case group and control group was about 7.3% and 0.8%. After adjusting for possible confounding factors, Cox regression analysis results showed that mother suffering from thalassemia (aRR=3.45, 95%CI: 1.35-8.81, P=0.010), fathers suffering from thalassemia (aRR=4.93, 95%CI: 2.16-11.21, P<0.001) and both mother and farther suffering from thalassemia (aRR=5.13, 95%CI: 2.62-10.04, P<0.001) were associated with preterm birth. Mother suffering from thalassemia (aRR=12.98, 95%CI: 4.91-34.30, P<0.001), fathers suffering from thalassemia (aRR=9.40, 95%CI: 3.40-25.95, P<0.001) and both mother and farther suffering from thalassemia (aRR=10.74, 95%CI: 4.44-26.00, P<0.001) were associated with low birth weight. The newborn whose parent all suffered from thalassemia had higher risks for preterm birth (χ2=22.72, P<0.001)and low birth weight (χ2=34.03, P<0.001) compared with those only with mother or father suffering from thalassemia.@*Conclusion@#Parental thalassaemia, including both sides and single side, might increase the risks of preterm birth and low birth weight for newborn, and the risks might be higher in newborn with both mother and father suffering from thalassaemia.

ABSTRACT

Objective@#To investigate the efficacy and safety of IA regimen which contains idarubicin (IDA) 8 mg/m2, 10 mg/m2 or 12 mg/m2 as induction chemotherapy for adult patients with de-novo acute myeloid leukemia (AML) .@*Methods@#A total of 1 215 newly diagnosed adult AML patients, ranging from May 2011 to March 2015 in the First Affiliated Hospital of Soochow University and other 36 clinical blood centers in China were enrolled in the multicenter, single-blind, non-randomized, clinical controlled study. To compare the response rate of complete remission (CR) , adverse events between different dose idarubicin combined with cytarabine (100 mg/m2) as induction chemotherapy in newly diagnosed patients of adult AML.@*Results@#Of 1 207 evaluable AML patients were assigned to this analysis of CR rate. The CR rates of IDA 8 mg/m2 group, IDA 10 mg/m2 group and IDA 12 mg/m2 group were 73.6% (215/292) , 84.1% (662/787) and 86.7% (111/128) , respectively (P<0.001) . After adjusted for age, blast ratio of bone marrow, FAB classification and risk stratification, the odds ratios (95% CI) of IDA 10 mg/m2 group and IDA 12 mg/m2 group were 0.49 (0.34-0.70) and 0.36 (0.18-0.71) , as compared with the IDA 8 mg/m2 group (P<0.001, P=0.003) . In the intermediate and favorable groups, CR rates was 76.5% (163/213) , 86.9% (506/582) and 86.1% (68/79) in different doses of IDA (P=0.007) . Interestingly, IA regimen with IDA 10 mg/m2 was the only beneficial factor affecting CR in this group after adjusted for age, blast ratio of bone marrow and FAB classification[OR=0.47 (95% CI 0.31-0.71) , P<0.001]. CR rates in adverse group was 50.0% (18/36) , 60.6% (43/71) and 81.8% (18/22) respectively (P=0.089) . However, the odds ratios (95% CI) of IDA 12 mg/m2 when compared with the IDA 8 mg/m2 was 0.22 (0.06-0.80) , after adjusted for age, blast ratio of bone marrow and FAB classification. The median time (days) of neutrophil count less than 0.5×109/L in IDA 8 mg/m2 group, IDA 10 mg/m2 group and IDA 12 mg/m2 group were 14 (11-18) , 15 (11-20) and 18 (14-22) , respectively (P=0.012) and of platelet count lower than 20×109/L were 14 (7-17) , 15 (11-20) and 17 (15-21) , respectively (P=0.001) . The incidences of lung infection in the three groups were 9.8%, 13.5% and 25.2%, respectively (P<0.001) .@*Conclusions@#For young adult patients (aged 18-60 years) with AML in China, intensifying induction therapy with idarubicin 10 mg/m2 is clinically superior to IDA 8 mg/m2 and IDA 12 mg/m2 in favorable intermediate AML subgroup. However, idarubicin 12 mg/m2 is more suitable to adverse AML subgroup.

ABSTRACT

Objective To analyze the correlation between the expression of HIF-1α in multiple myeloma (MM) and clinical indexes in order to illustrate the expression and implication of HIF-1α gene in MM. Methods RQ-PCR method was used to amplify HIF-1α mRNA of bone marrow mononuclear cells isolated from 28 cases of MM patients and the control group. β-actin was used as internal standard. HIF-1α mRNA expression was analyzed by SDS software and the ratios of HIF-1α/ β-actin were calculated. Results The relative expression level of HIF-1α mRNA in MM bone marrow mononuclear cells was 12.68 times as that in control group. HIF-1α mRNA was positively correlated with β2-MG (r =0.575, P =0.000), ESR (r =0.522,P =0.000), LDH (r=0.286, P=0.044) and CRP (r =0.356, P =0.011). There was a negative correlation between HIF-1α mRNA and Hb (r =-0.556, P =0.000). Conclusion The expression of HIF-1α mRNA was up-regulated and HIF-1α was related to a number of clinical indexes. HIF-1α may be used to estimate the progress of MM and hopeful to be a new molecular target in cancer therapy.

ABSTRACT

Objective To investigate the status of expression and gene polymorphism of cytotoxic T lymphocyte-associated molecule4(CTLA4)on peripheral blood mononuclear cells(PBMCs)from patients with psoriasis.Methods Expression of CTLA4mRNA/antigen and polymorphism of CTLA4gene were analyzed in33and133patients with psoriasis confirmed clinically and/or pathologically,respectively.Expression of CT-LA4mRNA and antigen was detected by in situ hybridization and immmunohistochemistry.CTLA4exon1and3'untranslated region were amplified by polymerase chain reaction(PCR)and the amplified products were identified by single-stand conformation polymorphism(SSCP),restriction fragment length polymorphism(RFLP)or sequencing.Results Expression of both mRNA and antigen of CTLA4was significantly weaker on PBMCs induced by staphytococcal enterotoxin B(SEB)in patients with psoriasis than that in normal con-trols,without a regular pattern.The guanine49on exon1in association with fragment106bp of3'untranslat-ed region was shown to be linked to the susceptibility of psoriasis.Conclusion Defective translation and ex-pression of CTLA4take place in patients with psoriasis,which is possibly related to the polymorphism of CT-LA4.Our results suggest that CTLA4may be one of the candidate genes which cause autoimmunity in psoria-sis.
