ABSTRACT
Objective:To identify the association of sex hormone and sex hormone-binding globulin (SHBG) levels in patients with Graves′ disease.Methods:Between December 2017 and July 2019, 152 patients with Graves′ disease were enrolled in the Department of Endocrinology and Metabolism of Zhongshan Hospital, Fudan University. Parameters such as height, weight, thyroid function, sex hormone, fasting blood glucose, insulin, C-peptide, glycosylated albumin, HbA 1C, and liver function were collected. The associations between SHBG and bioclinical characteristics were analyzed. Results:The glycosylated albumin level was negatively associated with SHBG in all subjects ( β=-0.308, P<0.01), while this association was not significant after the adjustment for thyroid hormones. Male patients had significantly lower SHBG level than female patients ( P<0.01). In male patients, SHBG was associated with luteinizing hormone ( r=0.465, P<0.01), estradiol ( r=0.629, P<0.01), testosterone ( r=0.786, P<0.01). While in female patients, SHBG was also associated with testosterone ( r=0.191, P<0.05). In multivariate linear regression analysis, estradiol was independently associated with SHBG ( β=0.329, P<0.01) in male subjects. Conclusion:The hypogonadism and infertility in Graves′ disease patients could partially be attributed to the association between SHBG and Graves′ disease.
ABSTRACT
Objective@#To investigate the incidence, risk factors and survival of bronchiolitis obliterans syndrome (BOS) in patients who had undergone haplo-hematopoietic stem cell transplantation (haplo-HSCT) .@*Methods@#This study retrospectively analyzed clinical data of 444 consecutive patients who underwent haplo-HSCT and survived at least 100 days after transplantation in the First Affiliated Hospital of Soochow University between January 2013 and December 2015.@*Results@#By the end of follow-up on January 1, 2018, 25 patients (5.63%) had BOS (BOS group) . The median onset time of BOS was 448 (165-845) d post transplantation, the 1-year, 2-year and 3-year cumulative incidence of BOS was 1.6% (95%CI 1.5%-1.6%) , 4.8% (95%CI 4.7%-4.8%) and 5.8% (95%CI 5.7%-5.8%) , respectively. Among patients with chronic graft-versus-host disease (cGVHD) , the cumulative incidence at the same intervals was 2.8% (95%CI 2.7%-2.8%) , 9.5% (95%CI 9.4%-9.5%) and 11.5% (95%CI 11.4%-11.6%) , respectively. In the multivariate analysis, the risk factors for BOS were high-risk primary disease, Ⅱ-Ⅳ aGVHD and preceding cGVHD with other organs. The 3-year overall survival (OS) was lower among patients with than those without BOS, but the difference was not significant [71.8% (95%CI 53.9%-89.6%) vs 72.4% (95%CI 68.1%-76.7%) , P=0.400]. Overall 1-year, 3-year survival of patients with BOS from the time of diagnosis was 78.4% (95%CI 61.5%-95.3%) and 37.0% (95%CI 2.5%-71.5%) , respectively, significantly less than those without (93.9% and 89.3%, from day 448 after transplantation, respectively, P<0.001) . Furthermore, we found a significantly higher incidence of transplantation-related mortality (TRM) in patients with compared with patients without BOS (28.2% vs 10.9%, P<0.001) . The main risk factor for OS of BOS patients was the severity of pulmonary impairment at the time of diagnosis. Patients who developed severe BOS had a worse OS than those with moderate and mild BOS (P=0.049) .@*Conclusion@#BOS is a severe pulmonary complication of haplo-HSCT. High-risk primary disease, Ⅱ-Ⅳ aGVHD and preceding cGVHD were independent risk factors for BOS. Patients who developed BOS had a worse OS than those without BOS. The main risk factor for OS of BOS patients was the severity of pulmonary impairment.
ABSTRACT
Objective@#To investigate herpesvirus infection in early stage of hematopoietic stem cell transplantation (HSCT) by multiplex polymerase chain reaction (PCR), and to explore the association between multiple herpesviruses infection and clinical characteristics in HSCT patients and its impact on post-transplant complications and prognosis.@*Methods@#A total of 734 peripheral blood samples were collected from 90 patients undergoing HSCT in the Department of Hematology, the First Affiliated Hospital of Soochow University between February 2017 and August 2017. The peripheral blood specimens were obtained before and within 90 days after transplantation at different time points. Lab-Aid824 Nucleic Acid Extraction Mini Reagent was used to extract DNA and multiplex PCR assay was used to simultaneously detect 8 kinds of human herpesviruses from genomic DNA. The incidence of various herpesvirus infections, its correlation with clinical features and effects on post-transplant complications and prognosis were analyzed.@*Results@#The median follow-up time was 192 (range: 35-308) days. Among the 90 patients before transplantation, the incidence of herpes virus infection was 35.6% (32/90), including 12.2% (11/90) with one herpes virus infection and 23.3% (21/90) with multiple viruses infection. The incidence of herpes virus infection after transplantation was 77.8% (70/90), including 20.0% (18/90) with one herpes virus infection and 57.8% (52/90) with multiple herpes virus infection. Among the 52 patients with multiple herpes viruses infection, 30 (57.7%) patients were infected by 2 kinds of viruses, 18 (34.6%) patients by 3 kinds of viruses and 4 (7.7%) patients by 4 kinds of viruses. There was a correlation between HHV-6 and HHV-7 herpesvirus infection (OR=13.880, Q=0.026). EBV infection was related to HHV-7 infection (OR=0.093, Q=0.044). The age of patients was correlated with the incidence of HHV-1 infection before transplantation. There were 24 patients in our study experienced clinical symptoms associated with viral infection. The main manifestations were hemorrhagic cystitis (HC), interstitial pneumonia, enteritis, viral encephalitis and fever of unknown origin. EBV infection was related to HLA incompatibility and the inconsistent of the ABO blood group and grade Ⅱ-Ⅳ aGVHD after transplantation. HLA incompatibility and the unrelated donor and grade Ⅱ-Ⅳ aGVHD were related to multiple viruses infection.@*Conclusion@#Multiple herpesviruses were common in patients undergoing HSCT, which were closely related to HLA mismatch, unrelated donor and grade Ⅱ-Ⅳ aGVHD.
ABSTRACT
Objective@#To explore the efficacy and safety of chimeric antigen receptor T (CAR-T) cells in the treatment of central nervous system leukemia (CNSL).@*Methods@#Two leukemia patients with CNSL were treated with CD19-CAR-T cells. The process and results of the entire treatment is reported and related literature review is conducted.@*Results@#The patients were diagnosed as acute myeloid leukemia (AML)-M2 with B lymphoid antigen expression and B cell acute lymphoblastic leukemia(B-ALL) by morphology and immunophenotype assay. The immunophenotype was consistent with the abnormal manifestations of AML-M2 and B-ALL. Their clinical manifestations and laboratory tests met the diagnostic criteria of CNSL. The diagnosis was clear and the two patients were treated with CD19-CAR-T cell immunotherapy. Central nervous system symptoms were relieved. The imaging abnormalities of patient one has disappeared but cytokines release syndrome (CRS) occurred during the treatment. Cerebrospinal fluid of patient two was negative and no obvious CRS reaction was found.@*Conclusions@#CAR-T cell immunotherapy is likely to induce the remission of CNSL and improve the prognosis.

ABSTRACT
Objective21 -hydroxylase deficiency ( 21-OHD) patients are at high risk of developing metabolic syndrome.Low dose of glucocorticoid is crucial in the treatment.This study is to investigate the effect of glucocorticoid therapy on potential metabolic disorders.Methods Thirty-two treated and 31 untreated 21-OHD patients were recruited.The components of metabolic syndrome were investigated in both groups.Results Serum testosterone [ (0.61 ±0.12 vs 4.10±0.66) ng/ml,P＜0.01 ],17-(OH) progesterone[ 17-OHP,( 14.83±3.48 vs 48.52±4.72 )ng/ml,P＜0.01 ],dehydroepiandrosterone sulfate[ DHEAS,(55.7±23.6 vs 405.2±65.7 ) μg/dl,P＜0.01 ],and ACTH[ ( 105.8±44.7 vs 617.4± 163.3 ) pg/ml,P＜0.01 ] levels were significantly reduced,whereas body mass index [ ( 23.2±0.9 vs 21.1 ±0.5 ) kg/mz,P＜0.05 ],systolic blood pressure [ ( 120.5 ± 1.3 vs 115.5 ± 1.8 ) mm Hg,P＜0.05,1 mm Hg =0.133 kPa ],serum triglyceride [ ( 1.8±0.2 vs 1.1 ±0.1 ) mmol/L,P＜0.05 ],and homeostasis model assessment for insulin resistance [ HOMA-IR,( 2.07 ± 0.27 vs 1.16 ± 0.12 ),P ＜ 0.01 ] were markedly increased in glucocorticoid treated group.Multivariates regression analysis showed that body mass index was the most important risk factor for HOMA-IR.The correlation of glucocorticoid replacement and HOMA-IR was not observed after adjustment of age and body mass index.ConclusionGlucocorticoid treatment increases body weights,which leads to insulin resistance and metabolic disorders for 21-OHD patients.More attention should be paid to control BMI and metabolic disturbances in 21-OHD patients.
ABSTRACT
The clinical and genetic characteristics in a patient with 46,XY complete gonadal dysgenesis was investigated. Clinical features and laboratory data were collected from the patient and the family. The exon of SRY gene was amplified by PCR and sequenced. The patient presented with primary amenorrhea, nonambiguous female external genitalia, slight breast development, and no axillary hair or pubic hair. The female internal reproductive organs consisted of uterus and streaks of ovarian tissue. Howerver, the chromosome karyotype was 46,XY. A missense mutation of A66T in SRY gene was identified, which was not previously reported. The novel SRY mutation caused the sex reversal in this 46,XY female patient.

There was significant difference except for the incidence of cGVHD.Conclusion Allogeneic hematopoietic cell transplantation may be appropriate for older patients with malignant hematological diseases.
ABSTRACT
Objective To illustrate the clinical relevance of distinct PML-RARα fusion gene isoforms in acute promyelocytic leukemia (APL). Methods The nested reverse transcriptase polymerase chain reaction (RT-PCR) was used to detect the long (L) or short (S) PML-RARα fusion gene isoforms in 92 newly diagnosed APL so as to evaluate the clinical feature, therapeutic reaction and prognosis of the two fusion gene isoforms. Results PML-RARα fusion gene was positive in all 92 APL patients, of which 52(56.5 %) was L type and 40 (43.5 %) was S type. There were no significant differences between L type and S type in the aspect of sex, age, white blood cell count,the percentage of bone marrow blasts plus promyeloeytes and chromosome before treatment. And there were no significant differences between the two isoforms in complete remission (CR) rate, the time of getting CR as well as the occurrence of retinoic acid syndrome (RAS), disseminated intravascular coagulation (DIC), intraeranial hemorrhage. Also, there were no significant differences in overall survival rate (OS) and relapse-free survival rate (RFS) between the two isoforms. Conclusion PML-RARα fusion gene isoforms in APL were not correlated with clinical therapeutic effect or prognosis.
ABSTRACT
Objective To investigate the clinical and laboratory features of acute promyelocytic leukemia (APL).Methotis 513 APL patients in the last two decades were retrospectively analyzed in this research.We investigated the clinical features including age,sex,abnormality of peripheral hemogram before treatment.therapeutic effect and follow-up and laboratory data such as morphology,immunology,cytogenetics and molecular biology(MICM).Results The median age of the APL patients was 33 years old and the ratio of male and female was 1.21:1.Before treatment,the median level of WBC was 4.3×109/L and the deteetion rate of abnormal promyelocyte on blood film was 85.8%;with immunophenotypie detection,the expression levels of CD117、CD34、HLA-DR、CD7、CD14 and CD19 in APL were found to be lower and the expression 1evels of CD2、CD33 and MPO higher than those in other subtypes of acute myelocytie leukemia(AML)(beth P<0.01).Specific abnormal chromosome t(15;17)was detected in 91.7%of the patients,of whom 75.9%had standard translocation of t(15;17),being the most common one and 15.8% of the patients had t(15;17)with additional abnormal chromosome.There was only 7.5%of the patients with nolnlal karyotype.However,the presence of both simple translocation and complex translocation was seldom seen.With molecular biological detection.PML/RARα fusion gene positive rate was 99.6%.In a relativelv long clinical follow-up,we found that the complete remission(CR)rate in APL patients was 84.7%.incidence of DIC was 13.4%and five-year survival rate was 30.7%.111e median count of WBC in CR group was lower than that non-remission group(P<0.01).There were no significant differences on expressions of CD34 and CD2 and changes of cytogenetics between the two groups(P>0.05).Conclusions Comprehensive evaluation of MICM could be of important significance in the diagnosis and prognosis iudgrnent for APL patients.The CR rate in these patients with high WBC eount was considerable low.
