Steroid-refractory (SR) acute graft-versus-host disease (aGVHD) is one of the leading causes of early mortality after allogeneic hematopoietic stem cell transplantation (allo-HSCT). We investigated the efficacy, safety, prognostic factors, and optimal therapeutic protocol for SR-aGVHD patients treated with basiliximab in a real-world setting. Nine hundred and forty SR-aGVHD patients were recruited from 36 hospitals in China, and 3683 doses of basiliximab were administered. Basiliximab was used as monotherapy (n = 642) or in combination with other second-line treatments (n = 298). The cumulative incidence of overall response rate (ORR) at day 28 after basiliximab treatment was 79.4% (95% confidence interval [CI] 76.5%-82.3%). The probabilities of nonrelapse mortality and overall survival at 3 years after basiliximab treatment were 26.8% (95% CI 24.0%-29.6%) and 64.3% (95% CI 61.2%-67.4%), respectively. A 1:1 propensity score matching was performed to compare the efficacy and safety between the monotherapy and combined therapy groups. Combined therapy did not increase the ORR; conversely, it increased the infection rates compared with monotherapy. The multivariate analysis showed that combined therapy, grade III-IV aGVHD, and high-risk refined Minnesota aGVHD risk score before basiliximab treatment were independently associated with the therapeutic response. Hence, we created a prognostic scoring system that could predict the risk of having a decreased likelihood of response after basiliximab treatment. Machine learning was used to develop a protocol that maximized the efficacy of basiliximab while maintaining acceptable levels of infection risk. Thus, real-world data suggest that basiliximab is safe and effective for treating SR-aGVHD.

To analyze the characteristics of gene mutation and overexpression in newly diagnosed multiple myeloma (NDMM) patients.Bone marrow cells from 208 NDMM patients were collected and analyzed. The gene mutation of 28 genes and overexpression of 6 genes was detected by DNA sequencing. Chromosome structure abnormalities were detected by fluorescence in situ hybridization (FISH).Gene mutations were detected in 61 (29.33%) NDMM patients. Some mutations occurred in 5 or more cases, such as NRAS, PRDM1, FAM46C, MYC, CCND1, LTB, DIS3, KRAS, and CRBN. Overexpression of six genes (CCND1, CCND3, BCL-2, CCND2, FGFR3, and MYC) were detected in 83 (39.9%) patients, and cell cycle regulation gene was the most common. Single nucleotide polymorphisms (SNP) changes were detected in 169 (81.25%) patients, the TP53 P72R gene SNP (70.17%) was the most common. Abnormality in chromosome structure was correlated to gene overexpression. Compared to the patients with normal chromosome structure, patients with 14q32 deletion showed higher proportion of CCND1 overexpression. Similarly, patients with 13q14 deletion showed higher proportion of FGFR3 overexpression, whereas patients with 1q21 amplification showed higher proportion of CCND2, BCL-2 and FGFR3 overexpression.There are multiple gene mutations and overexpression in NDMM. However, there is no dominated single mutation or overexpression of genes. The most common gene mutations are those in the RAS/MAPK pathway and the genes of cyclin family CCND are overexpression.初治多发性骨髓瘤患者的基因突变及表达异常.分析初治多发性骨髓瘤（NDMM）患者常见基因的突变及表达异常.取208例NDMM患者的骨髓细胞，用DNA测序法检测6种基因的表达水平及28种基因的突变状态。应用FISH法检测多发性骨髓瘤常见的细胞遗传学异常.61例（29.33%）NDMM患者检测到基因突变，≥5例患者发生突变的基因包括NRAS、PRDM1、FAM46C、MYC、CCND1、LTB、DIS3、KRAS和CRBN。83例（39.90%）患者检测到6种基因的过表达，以细胞周期调节基因的过表达为主，分别是CCND1、CCND3、BCL-2、CCND2 FGFR3和MYC。169例（81.25%）患者检测到基因单核苷酸多态性改变，主要为TP53基因P72R多态性 (70.17%)。染色体结构异常与基因表达异常有一定相关性，与染色体结构正常者相比较，14q32缺失患者中CCND1基因过表达比例更高，13q14缺失患者中FGFR3过表达比例更高，而1q21扩增患者中CCND2、BCL-2、FGFR3基因过表达比例更高.NDMM患者存在多种基因突变和表达异常，但是缺乏主要的单个基因突变或表达异常。累及RAS/MAPK通路的基因突变及细胞周期蛋白CCND的过表达是常见的基因异常.

Background: Allogeneic stem-cell transplantation (SCT) is a well-established immunotherapeutic strategy for multiple myeloma (MM) with a potent and often sustained graft-vs.-myeloma effect. This multicenter investigation aimed to analyze the complications and survival of haploidentical SCT in patients with MM, and compare the main outcomes with matched-related donors (MRDs). Methods: Haploidentical and MRD SCT was identified from a cohort of 97 patients with MM who received a myeloablative transplantation in 13 hospitals from May 2001 to December 2017. A matched-pair analysis was designed. For each haplo recipient, the recipients were randomly selected from the MRD group and were matched according to the following criteria: year of the hematopoietic SCT (±2 years), disease status at transplantation, and the length of follow-up. Results: Seventy cases received MRD and 27 received haploidentical transplantation. The two groups showed no significant differences regarding age, gender, cytogenetic risk, and diagnostic stage. The cumulative incidences of non-relapse mortality (NRM) at 1 and 3 years based on donor type were 20.5% (95% confidence interval [CI], 10.90–30.10%) and 24.2% (95% CI, 13.81–34.59%) for the MRD group and 16.80% (95% CI, 1.71–31.89%) and 28.70% (95% CI, 8.71–48.69%) for the haplo group, respectively. Cumulative incidence of NRM did not differ significantly between the two groups (χ2 = 0.031, P = 0.861). The cumulative incidences of progression-free survival (PFS) and 1 year and 3 years by type of donors were 59.8% (95% CI, 48.24–71.36%) and 45.4% (95% CI, 33.44–57.36%), and 65.6% (95% CI, 47.18–84.02%) and 26.8% (95% CI, 7.59–46. 01%) for MRD and haploidentical donor, respectively. Cumulative incidence of PFS did not differ significantly between the two groups (χ2 = 0.182, P = 0.670). In multivariate analyses, no statistically significant differences were observed between haploidentical and MRD for relapse, NRM, PFS, and overall survival. There were no statistically differences on main outcomes after haploidentical and MRD. Conclusion: Haploidentical SCT could be performed safely and feasibly for patients with MM in need. Key words: Allogeneic stem-cell transplantation; Multiple myeloma

In untreated ALL, the expression of lncRNA RP11-69I8.3 in children is significantly lower than that in adult. In B-ALL patients, the lncRNA RP11-69I8.3 is not relevant with the immunophenotype.

Polydatin (PD), a natural precursor of resveratrol, has a variety of biological activities, including anti‑tumor effects. However, the underlying molecular mechanisms of the anti-cancer activity of PD has not been fully elucidated. The present study demonstrated that PD significantly inhibited the proliferation of the MOLT-4 leukemia cell line in a dose‑ and time-dependent manner by using Cell Counting Kit‑8 assay. PD also dose-dependently increased the apoptotic rate and caused cell cycle arrest in S phase in MOLT‑4 cells, as revealed by flow cytometry. In addition, PD dose-dependently decreased the mitochondrial membrane potential and led to the generation of reactive oxygen species in MOLT-4 cells. Western blot analysis revealed that the expression of anti‑apoptotic protein B-cell lymphoma 2 (Bcl-2) was decreased, whereas that of pro‑apoptotic protein Bcl‑2‑associated X was increased by PD. Furthermore, the expression of two cell cycle regulatory proteins, cyclin D1 and cyclin B1, was suppressed by PD. Of note, the pro‑apoptotic and cell cycle‑inhibitory effects of PD were potentiated by Janus kinase 2 (JAK2) inhibition. In conclusion, the results of the present study strongly suggested that PD is a promising therapeutic compound for the treatment of leukemia, particularly in combination with JAK inhibitors.

In 27 cases of ALL, IncRNA RP11-87C12.5 expression significantly increased in cCD79a low expression group, compared with cCD79a high expression group (P=0.004). IncRNA RP11-87C12.5 expression did not relate with other CD molecules of immunoclassification.The expression of LncRNA RP11-87C12.5 is high in newly diagnosed ALL group and low in complete remission ALL group. In B-ALL, the expression of IncRNA RP11-87C12.5 significantly enhances in cCD79a low expression group. In newly diagnosed ALL group, compared with low expression group, lncRNA RP11-87C12.5 high expression group have higer remission rate and relapse rate, but the difference was not statistically significant.

To analyze the clinical characteristics of cytomegalovirus(CMV) infection after allogenic hematopoietic stem cell transplantation(allo-HSCT) and the effect of preemptive therapy.A total of 134 patients who underwent allo-HSCT from March 2010 to March 2015 in the Department of Hematology of our hospital were enrolled in this study. The CMV infection rate, the median time of CMV infection occurence, and the risk factors for CMV infection after allo-HSCT, the response rate of preemptive treatment and the median time of CMV-DNA turning negative were analyzed. Five-year overall survival rate was compared between the patients with or without CMV infection.The incidence of CMV viremia was 55.2％(74／134), and the median time for the CMV with CMV-DNA positive for the first time was 34 days(14-283) after allo-HSCT．Both univariate and multivariate analysis showed that the thymoglobulin(ATG) used in conditioning regimen and Ⅱ-Ⅳ grade of aGVHD were the risk factors for CMV viremia. After preemptive treatment the 85.1% of patient with CMV viremia turned negative, and the median time of CMV-DNA turning negative were 15 days(5-82), only 2 patients died of CMV pneumonia. Five-year overall survival rate of the patients with or wihout CMV viremia was 49% and 66.3% respectively, and the difference between the 2 groups was significant(P=0.041）.The ATG used in conditioning regimen and Ⅱ-Ⅳ grade of aGVHD may increase the incidence of CMV infection after allo-HSCT, and the preemptive thrapy can effectively prevent the CMV viremia turning to CMV disease.

To explore the clinical features of multiple myeloma with different renal pathology, and to evaluate its prognosis.Clinical features and prognosis of 46 multiple myeloma patients with different renal pathology were analyzed retrospectively. According to renal pathology, the 46 patients were divided into 3 groups: cast nephropathy (24 cases), amyloidosis (15 cases) and other type (7 cases).By durie-Salmon staging system, 70.8% cases (17/24) in the cast nephropathy group were in Phase III, 90.9% (20/24) were in subtype B, while in amyloidosis group 53.3% (8/15) were in Phase I, 40% (6/15) were in subtype B, and in other types group, 71.4% (5/7) were in phase III, 57.1% (4/7) were in subtype B, the differences among them were statisticaily significant (P0.05). In cast nephropathy group, the monoclonal immunoglobulin could not be detected in 75% (18/24) cases, which was light chain type, while immunoglobulin in amyloidosis and other type groups were mainly IgG type in 73.3% (11/15) and 71.4% (5/7) respectively, the difference among them also was statistically significant (P0.05). The median survival time of patients in cast nephropathy group was 11 months, while that in amyloidosis and other type groups was 19 and 18 months, the differences among 3 groups were not significant (P0.05).In renal pathologic types, the cast nephropathy is the most common, followed by amylordosis. The multiple mycloma patients with defferent renal pathology show different clinical features. The multiple myeloma patients with renal amyloidosis have slighter clinical manifestations possibly with a better prognosis. Meanwhile, the non-amyloidosis types, especially cast nephropathy may predict a more serious manifications with poor prognosis.

To investigate the CD25 expression in patients with acute myeloid leukemia (AML) and its significance.Clinical data of 168 newly diagnosed AML patients (except APL) were collected. The expression of CD25 in AML patients and its clinical characteristics were retrospectively analyzed.The leukemia cells of 29 out of 168 cases (17.26%) expressed CD25 antigen. Most of CD25 positive AML patients were occurred in patients with unfavourable or normal karyotype, higher WBC and Plt count at diagnosis and higher percentage of blasts in peripheral blood and bone marrow. Compared with CD25(-) AML patients, CD25(+) AML patients had lower CR rate (the CR rate of 1 course of treatment were 49.02% and 16.00%, respectively, P0.05, the CR rate of 2 courses of treatment were 74.60% and 46.67%, respectively, P0.05), and the OS time of CD25(+) AML patients were obviously shorter (P0.05). The OS in CD25(+) AML patients with unfavorable karyotype were not significantly different from that in patients with intermediate karyotype (P0.05).The CD25(+) AML patients have some typical clinical features, and the expression of CD25 in AML is an risk factor independent of the chromosome karyotype in terms of low complete remission rate and short survival time.

To evaluate the clinical characteristics of multiple myeloma (MM) combined with renal amyloidosis and its curative efficacy and prognosis.The clinical data of 22 cases of newly diagnosed multiple myeloma combined with renal amyloidosis treated in our hospital from November 2011 to July 2015 were analyzed retrospectively.According to Intenational Staging System (ISS), among above-menthioned 22 patients the ISS II accounted for 77.2% (17/22), ISS III accounted for 22.8% (5/22). The patients with renal impairment accounted for 36.4% (8/22), with anemia 40.9% (9/22), with serum album35 g/L 86.4% (19/22), with urinary protein positive 100% (22/22). The evaluation of the curative efficacy of the 22 cases was as follows: CR 13.6% (3/22); VGPR 4.5% (1/22); PR 22.8% (5/22); SD 45.5% (10/22); PD 13.6% (3/22). Out of 9 patients with effective treatment, 3 cases (3/9, 33.3%) achieved "improved" in renal amyloidosis, 4 cases (4/9, 44.5%) achieved stable in renal amyloidosis, 2 cases (2/9, 2%) achieved "worsened" in renal amyloidosis. Among 17 cases who were followed up, 7 cases died, 10 cases survived, the average duration of follow-up for these cases was 11 (1-37) months, the median overall survival (OS) time was 19 (95% CI 9.2-28.8) months.MM with renal amyloidosis is rare, refractory and has a poor prognosis. Whether there is impairment of kidney function or not, renal amyloidosis shall be taken into consideration if the MM patients got massive proteinuria especially nephritic syndrome. Bortezomib may improve the curative efficacy.

The expression of N-Cadherin in bone marrow CD38⁺/CD138⁺ cells from multiple myeloma patients was detected by flow cytometry. The relationship between N-Cadherin expression and clinical prognostic factors was analyzed.Among 64 cases of MM, the expression of N-Cadherin in 17 patients (26.56%) was high (20%), while that in 47 cases (73.44%) was low (20%); The differences of N-Cadherin expression in disease staging and classification, known prognostic factors, myeloma cell antigen expression and bone damage between patients with high and low N-Cadherin expression were not statistically different; the difference N-Cadherin expression in genetic abnormalities such as D13S319 deletion, RB1 deletion and IGH gene rearrangement between above-methioned two groups was not significant. The 1q21 amplification rate in the group with high expression of N-Cadherin was enhanced significently; the overall survival (OS) times of patients with abnormally high and low expression levels of N-Cadherin were 26.7 months and 55.5 months respectively, and the difference was statistically significant (P0.05).The high expression of N-Cadherin in multiple myeloma may be one of the indicator for poor prognosis of MM, which may be related with 1q21 amplification.

The aim of this study was to explore the reversing effect of cinobufacini on multidrug resistance of Raji/ADR cells and its mechanisms. The growth inhibitory rate, half inhibitory concentration (IC50), reversing multiples to adriamycin- resistance were detected by MTT, and the curve of growth inhibitory rate was drawn; the MDR-1 and MRP-1 gene transcription was determined by RT-PCR; the expressions of P-gp and MRP-1 proteins were assayed by Western blot and flow cytometry. The results showed that the inhibitory rates of cinobufacini on Raji and Raji/ADR cells at 72 h were 75.6% and 69.3% respectively, the IC50 were 3.9 mmol/L and 4.6 mmol/L without significant difference (P0.05). The reversing multiples to adriamycin-resistance were 255.7 multiples, the transcription of mdr-1 and mrp-1 genes and the expression of P-gp and MRP-1 proteins significantly decreased (P0.05) in Raji/ADR cells after the treatment with cinobufotalin. It is concluded that cinobufotalin can reverse the adriamycin-resistance in Raji/ADR cells and the expression of P-gp and MRP-1 proteins were down-regulated through the transcriptional pathway. The cinobufotalin is an effective reversal agent for the multidrug resistance of tumors.

To investigate the risk factors, clinical features, efficacy and adverse reactions in patients of hematologic diseases with invasive fungal infections (IFI).The risk factors and clinical features were retrospectively analyzed to compare the efficacy and safety of itraconazole with amphotericin B in treatment of IFI in 76 patients with hematologic diseases.Of the 76 patients, 68 (89.5%) used broad-spectrum antibiotics, 64 (84.2%) were treated with more than 2 courses chemotherapy, 43 (56.6%) were under agranulocytosis, 34 (44.7%) were using glucocorticoid for long terms, 27 (35.5%) were with peripheral or central venous catheter. The overall effective rates of itraconazole and amphotericin B were 60.5% and 61.5% respectively (P = 0.929). There was a significant difference between itraconazole and amphotericin B in hypokalemia (14.0% vs 42.4%, P = 0.005) while no other differences in adverse reactions were found.The risk factors of patients in hematologic diseases with IFI include chemotherapy, using broad septum antibiotics and agranulocysis. The therapeutic effect of itraconazole and amphotericin B in treatment of IFI is similar. The adverse reactions of itraconazole is less and slighter than amphotericin B.

To elucidate the clinical features, response rate, prognosis and clonal evolution of aplastic anemia (AA) with macrocytic anemia (mAA).The clinical features at initial diagnosis and data in follow up of mAA hospitalized from January 2000 to October 2011 were analyzed retrospectively.(1) Of 153/568 (26.9%) cases of mAA at initial diagnosis, 114(74.5%)were non-severe AA (NSAA), 39(25.5%)severe AA (SAA) and 0 very severe AA (VSAA), while the proportion was 16.2%, 45.2%, and 38.6% in 376 normocytic anemia AA (nAA), and the difference is statistically significant(χ(2) = 181.390; P = 0.000). The median age of mAA was significantly higher than that of nAA \[30(4 - 70)years vs 19 (3 - 68) years, P = 0.001\]. (2) There were no statistical difference in hemoglobin, absolute neutrophil count (ANC), platelet count (PLT), response rate after 6 months treatment and overall survival (OS) between mAA and nAA grouped in SAA and NSAA respectively. In SAA, the reticulocyte count (Ret) of mAA was significantly higher than that of nAA \[23.90(2.99 - 61.00)×10(9)/L vs 13.1(0 - 70.60)×10(9)/L, P = 0.000\] and the proportion of erythroid cells in bone marrow of mAA was also higher \[23.5 (0 - 58) vs 14.5 (0 - 65), P = 0.043\], while they did not differ significantly in NSAA. (3) The proportion of AA with PNH clones or abnormal cytogenetics did not differ significantly in mAA and nAA groups before treatment. The incidences of AA evolved to PNH in mAA and nAA was not statistically significant (7/153 vs 9/376, χ(2) = 1.099, P = 0.294) and so was the incidence of evolution to MDS/AML(3/153 vs 13/376, χ(2) = 0.399, P = 0.528).In presented with macrocytic anemia at initial diagnosis of AA, higher proportion of NSAA, elderly age, higher Ret and proportion of erythroid cells are features, but being no statistical difference in the response rate, OS, and proportion of clonal evolution.

This study was purposed to analyze the clinical features and evaluate the efficacy of thalidomide combined with VAD regimen for treatment of osteosclerotic myeloma (POEMS syndrome). The data of 27 patients with POEMS syndrome in the First Affiliated Hospital of Zhengzhou University were analyzed retrospectively, including clinical manifestations, laboratory tests, treatments and prognosis. The results showed that the polyneuropathy was observed in 27 patients (27/27), hepato-spleno-lymphadenectasis was found in 15 patients (15/27), endocrinopathy was found in 24 patients (24/27), skin changes was observed in 22 patients (22/27). M protein was found in 23 patients (23/27); in addition to these clinical manifestations, the papilledema serous cavity effusion and sclerotic bone lesion were also frequently observed in patients with POEMS syndrome. The remission rates of treatment of POEMS syndrome with thalidomide combined with VAD regimen for organomegaly, edema, skin changes, and endocrinopathy were 60, 58.3, 41 and 45.8 respectively. The level of serum M protein and the nervous system ODSS value decreased greatly after treatment (P0.01). It is concluded that the clinical characteristics of POEMS syndrome are complicated and easy to be misdiagnosed, and the evidence of monoclonal plasma cell hyperplasia should be actively searched for those patients whose serum M protein is negative. Thalidomide combined with VAD regimen for treatment of patients with POEMS syndrome has advantages such as significant curative effects, less side-effects, good tolerance, and higher safety and can be chosen as a preferred approach.

The purpose of this study was to investigate the immunophenotyping characteristics of adult acute lymphoblastic leukemia (ALL) patients in groups of different ages. Immunophenotyping was performed in 260 ALL patients by flow cytometry using a panel of monoclonal antibodies and CD45/SSC gating. The results indicated that (1) all the 82 cases of T-cell acute lymphoblastic leukemia (T-ALL) expressed CD7 (100%) while the positive rate of CD2 remarkably decreased with aging. The positive rate of CD2 in patients aged 14 to 18 years (adolescents) was 91.67%, which is significantly higher than that in cases aged 19 to 35 years (young adults) and35 years (older adults) (65.71% and 43.48% respectively, p0.05); the positive rate of CD34 and HLA-DR increased with aging, there was significant difference of the HLA-DR expression between the older adults group (39.13%) and the other two groups (4.17% in adolescents and 11.43% in young adults respectively (p0.05). Moreover, there were significant differences of the myeloid antigen (MyAg) and CD13 expression between the older adults and younger adults (p0.05). (2) As to adult B-cell acute lymphoblastic leukemia (B-ALL), the positive rates of CD19 and HLA-DR in 178 cases were 100%; the positive rate of CD33 in young adults was significant higher than that in adolescents (p0.05), the differences of the other marker expressions failed to reach statistical significance in adult B-ALL patients. It is concluded that the immunophenotypes of adult T-ALL are evidently heterogeneous in different ages, and expression with more aberrant phenotypes indicates poor prognostic significance in patients older than 35 years. There is no significant association of immunophenotypes with ages among different age groups of adult B-ALL.

Hematopoietic stem cell transplantation could improve the prognosis of malignant hematologic diseases. Peripheral blood stem cell transplantation (PBSCT) has been gradually used as an alternative to bone marrow transplantation (BMT). This study was to observe the efficacy of allogeneic PBSCT (allo-PBSCT) or autologous PBSCT (auto-PBSCT) on malignant hematologic diseases.From Jul. 2003 to May 2006, 53 patients with malignant hematologic diseases underwent PBSCT in the First Affiliated Hospital of Zhengzhou University. PBSCs were mobilized with granulocyte colony-stimulating factor (G-CSF) or chemotherapy combined with G-CSF. Auto-PBSCT group received infusion of CD34+ cells at a median of 3.0x10(6) cells/kg; allo-PBSCT group received infusion of CD34+ cells at a median of 6.2x106 cells/kg. MAC regimen was used in auto-PBSCT group as conditioning regimen; amended BU/CY regimen was used in allo-PBSCT group. Methotrexate (MTX) combined with cyclosporine A (CsA) and MMF was used for graft-versus-host disease (GVHD) prophylaxis. Antilymphocyte globulin (ALG) was used in 1 patient with 1 mismatched locus in allo-PBSCT group.The median time for neutrophils to reach 0.5x10(9)/L and platelets to reach 20x10(9)/L were 13 days and 19 days in auto-PBSCT group, 12 days and 15 days in allo-PBSCT group. In allo-PBSCT group, grade I-III acute GVHD occurred in 31.4% cases, and chronic GVHD developed in 71.4% cases. The relapse rate was 38.9% in auto-PBSCT group and 5.7% in allo-PBSCT group. The 700-day disease-free survival rate (DFS) was 57.9% in auto-PBSCT group, and 69.5% in allo-PBSCT group.PBSCT can provide rapid hematopoietic reconstitution. It is a better choice for the cure of malignant hematologic diseases.

To evaluate cord blood stem cell transplantation (CBT) in the treatment of X-linked agammaglobulinemia, and observe the courses of the hematopoietic and immune reconstitution.A 14-year-old male patient with agammaglobulinemia received CBT from a 1/6 HLA-mismatched unrelated cord blood. The conditioning regimen was Bu/Cy/anti-CD3 antibody. CsA was given together with MMF and MTX for prophylaxis of GVHD. The patient received 0.42 x 10(8) nucleated cells/kg, containing 0.35 x 10(6) CD34(+) cells/kg.The recipient showed hematopoietic reconstitution on day 30 post-transplantation when ANC was 0.5 x 10(9)/L and BPC 20 x 10(9)/L. Sex chromosome analysis showed engraftment (donor 46, XX/recipient 46, XY = 4:1) on day 45. The recipient's blood group changed from AB to O, IgG from 1.1 g/L to 3.5 g/L, sex chromosome from 46, XY to full 46, XX, and mature B cells in peripheral blood from 0 to 5% on day 100, indicating immune reconstitution. At the last follow-up of 360 days, the patient without acute or chronic GVHD showed normal hemogram and myelogram, IgG 13.5 g/L and 10% mature B cells in peripheral blood, indicating the hematopoiesis and immune persistent reconstitution. No acute or chronic GVHD was developed.This is the first case report of successful treatment of X-linked agammaglobulinemia by HLA-mismatched unrelated CBT.
