ABSTRACT

OBJECTIVE: To investigate the risk factors of oral ulcers and bloodstream infection in patients with hematopoietic stem cell transplantation.

METHODS: The clinical data of 401 hematopoietic stem cell transplant patients in the First Affiliated Hospital of Zhengzhou University from January 2020 to December 2021 were retrospective analyzed, and the risk factors of oral ulcers and bloodstream infection statistical and analyzed.

RESULTS: Among the 401 patients, the incidence of oral ulcers was 61.3% (246/401), and the incidence of bloodstream infection was 9.0% (36/401). A total of 40 strains of pathogenic bacteria were isolated from 36 patients, including 26 strains of Gram negative strains (65%), 13 strains of Gram positive strains (32.5%), and 1 strain of fungi (2.5%). Single-factor analysis showed that oral hygiene was associated with the occurrence of bloodstream infection, and the Multi-factor analysis showed that age ≥14 years old, disease diagnosis of leukemia, and allogeneic hematopoietic stem cell transplantation were risk factors for oral ulcers.

CONCLUSION: The incidence of oral ulcers in patients with hematopoietic stem cell transplantation is high. The age ≥14 years, disease diagnosis of leukemia, and allogeneic hematopoietic stem cell transplantation were risk factors for oral ulcers in patients, and oral hygiene was associated with the occurrence of bloodstream infection.

ABSTRACT

AbstractObjective: To analysis the clinical data of patients after single-center hematopoietic stem cell transplantation (HSCT) and construct a predictive model for metabolic syndrome (MS) diagnosis.

METHODS: Ninety-three hematology patients who underwent HSCT at the First Hospital of Lanzhou University from July 2015 to September 2022 were selected to collect basic data, transplantation status and postoperative data, the clinical characteristics of patients with and without MS after transplantation were compared and analyzed. Logistic regression model was used to analyze the influence fators of MS after transplantation, and a predictive model of HSCT-MS diagnosis was constructed under the influence of independent influence factors. The model was evaluated using the ceceiver operating characteristic curve (ROC curve).

RESULTS: Metabolic syndrome occurred in 36 of 93 HSCT patients and did not occur in 57. Compared with non-HSCT-MS group, HSCT-MS had significantly higher fasting blood glucose (FBG) levels before transplantation, shorter course before transplantation, and higher bilirubin levels after transplantation (P<0.05). The statistically significant clinical indicators were subjected to multi-factor logistic regression analysis, and the results showed that pre-transplant high FBG, pre-transplant short disease course and post-transplant high bilirubin were independent influence factors for HSCT-MS. The standard error of predicting the occurrence of HSCT-MS based on the clinical model was 0.048, the area under the curve AUC=0.776, 95% CI :0.683-0.869, the optimal threshold was 0.58 based on the Jorden index at maximum, the sensitivity was 0.694, and the specificity was 0.772, which has certain accuracy.

CONCLUSION: A clinical prediction model for HSCT-MS based on logistic regression analysis is constructed through the analysis of clinical data, which has certain clinical value.

ABSTRACT

OBJECTIVE: To investigate the predictive value of complete blood count (CBC) and inflammation marker on the recurrence risk in children with Henoch-Schönlein purpura (HSP).

METHODS: One hundred and thirty-three children with HSP admitted to Cangzhou Central Hospital from February 2017 to March 2019 were enrolled. The clinical data of the children were collected, at the time of admission CBC and C-reactive protein (CRP) were detected. After discharge, the children were followed up for 1 year, the clinical data of children with and without recurrence were compared, and multivariate logistic regression was used to analyze the risk factors affecting HSP recurrence. Receiver operating characteristic (ROC) curve should be drawn and the predictive value of CBC and CRP on HSP recurrence should be analyzed.

RESULTS: In the follow-up of 133 children, 8 cases were lost and 39 cases recurred, with a recurrence rate of 31.20% (39/125). The age, skin rash duration, proportion of renal damage at the initial onset, percentage of neutrophils, percentage of lymphocytes, platelet count (PLT), mean platelet volume (MPV) and neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), MPV/PLT ratio (MPR), and CRP level of patients with recurrence were statistically different from those without recurrence (P <0.05). Multivariate logistic regression analysis showed that long skin rash duration, renal damage at the initial onset, increased PLR, high PLT, increased MPV and elevated CRP level were independent risk factors for recurrence in children with HSP (P <0.05). The ROC curve analysis showed that the area under the curve (AUC) of the combination of the four blood and inflammation marker (PLT, MPV, PLR and CPR) in the early prediction of HSP recurrence was 0.898, which was higher than the initial renal damage (AUC=0.687) and persistent skin rash time (AUC=0.708), with a sensitivity of 84.62% and a specificity of 83.72%.

CONCLUSION: Observation of CBC and CPR can predict the risk of HSP recurrence early and guide early clinical intervention.

ABSTRACT

OBJECTIVE: To investigate the risk factors and prognosis of cardiovascular damage in hypereosinophilia (HE).

METHODS: The clinical data of 62 patients with HE in Gansu Provincial Hospital from January 2015 to December 2020 were retrospectively analyzed, including clinical characteristics and laboratory indicators, and the influencing factors of survival and prognosis were also analyzed.

RESULTS: In this study, there were 34 males and 28 females, with a median age of 53.5 (20-79) years, 35 patients without cardiovascular damage, 27 patients with cardiovascular damage, including 22 patients with abnormal electrocardiogram (ECG) (81.5%), 18 patients with abnormal echocardiography (ECHO) (66.7%), 9 patients with single ECG abnormality, 5 patients with single ECHO abnormality, and other 13 patients with multiple abnormalities. In cardiovascular damage group, peripheral white blood cell count, absolute value of eosinophils, troponin T (TNT), N-terminal pro-B-type natriuretic peptide (NT-proBNP), interleukin (IL)-4 and IL-5 levels at initial diagnosis were significantly higher than those in the non-cardiovascular damage group (P <0.01), while hemoglobin, IL-2 and interferon-γ levels were significantly lower (P <0.01). There were no significant differences in age, sex, course of disease, etiological classification, platelet count, serum creatine kinase, serum creatine kinase isoenzyme and lactate dehydrogenase between the two groups (P >0.05). The 5-year overal survival rate of patients with cardiovascular damage was 88.9%, and that of patients without cardiovascular damage was 100%, the difference was statistically significant (P =0.012). The 5-year event-free survival (EFS) rate of patients with cardiovascular damage was 59.3%, and the median time was 37 (21-52) months, while that of patients without cardiovascular damage was 80%, and the median time was 63 (51-74) months (P =0.002). Age (>60 years old), course of disease (>24 months), NT-proBNP (>3 000 pg/ml), TNT (>100 ng/L), elevated IL-4 and IL-5 were associated with EFS shortening in patients with cardiovascular damage, which were independent risk factors for EFS.

CONCLUSION: The EFS rate in HE patients without cardiovascular damage is significantly higher than patients with cardiovascular damage. Age, course of disease, NT-proBNP, TNT, IL-4 and IL-5 are independent risk factors affecting EFS of patients with cardiovascular damage.

ABSTRACT

OBJECTIVE: To investigate the correlation between serum interleukin-33 (IL-33), β₂microglobulin (β₂-MG) levels and Durie-Salmon (DS) stage in patients with multiple myeloma (MM).

METHODS: 100 MM patients admitted to the First Affiliated Hospital of Fujian Medical University from March 2019 to January 2021 were selected and divided into stage I, stage II and stage III groups according to the DS staging system. A baseline data questionnaire of patients was designed, then the relevant baseline data and laboratory test results of patients were recorded. The levels of serum IL-33 and β₂-MG of all patients were detected, and the correlation between serum IL-33, β₂-MG levels and DS stage of MM patients was analyzed.

RESULTS: Among the 100 patients with MM, there were 32 cases in stage I, 39 cases in stage II and 29 cases in stage III. The levels of serum CRP and β₂-MG of patients in stage III were significantly higher than those of patients in stage I and II, and the levels of serum CRP and β₂-MG of patients in stage II were significantly higher than those of patients in stage I, the differences were statistically significant (P <0.05). The level of serum IL-33 of patients in stage III was significantly lower than that of patients in stage I and II, and the level of serum IL-33 of patients in stage II was significantly lower than that of patients in stage I, the differences were statistically significant (P <0.05). There was no statistical significant difference in other data between groups (P >0.05). Kendall’s tau-b correlation analysis showed that the levels of serum CRP and β₂-MG were positively correlated with DS stage in MM patients (r =0.534, 0.776), the level of serum IL-33 was negatively correlated with DS stage in MM patients (r =-0.759). Ordered logistic regression analysis and forest plot showed that the low level of serum IL-33 and the high level of β₂-MG were the influencing factors of high DS stage in MM patients (P <0.05 ).

CONCLUSION: DS stage of MM patients is closely related to the levels of serum IL-33 and β₂-MG, that is, the lower the serum IL-33 level and the higher the β₂-MG level, and the higher the DS stage of MM patients.

ABSTRACT

OBJECTIVE: To analyze the effect of CD56 expression on the prognosis of newly diagnosed multiple myeloma (MM) patients and explore the relationship between CD56 with clinical characteristics.

METHODS: In this retrospective study, the clinical data and laboratory parameters of 175 newly diagnosed MM patients from February 2015 to December 2020 in the Second Hospital of Anhui Medical University were collected. The patients were divided into CD56⁺ and CD56^– groups based on the expression of CD56, and the general data and laboratory parameters of the two groups were compared. The patients were followed up to June 30, 2021, and progression-free survival (PFS) and overall survival (OS) were recorded. PFS and OS curves of the two groups were plotted respectively, and the survival differences were compared. Univariate and multivariate Cox regression analyses were performed to analyze the effect of CD56 on the prognosis of newly diagnosed MM patients.

RESULTS: In 175 newly diagnosed MM patients, 57(32.6%) cases were in the CD56^–group and 118 (67.4%) cases in the CD56⁺ group. There was significant correlation between CD56 expression and ISS stage, ECOG score, platelets, β₂-microglobulin, creatinine, and extramedullary disease (all P <0.05). The incidence of extramedullary disease in the CD56^– group was significantly higher than that in the CD56⁺ group (29.8% vs 12.7%, P =0.006). The median follow-up time of the whole cohort was 23.6 (1.0-78.6) months. The median PFS of patients in CD56⁺ group and CD56^– group were 18.6 (1.2-77.6) and 12.2 (1.0-49.0) months, respectively, and the median OS of the two groups were 27.6 (1.4-77.7) and 19.7 (1.0-78.6) months, respectively. The 2-year PFS rate in the CD56⁺ group was significantly higher than that in the CD56^– group (57.6% vs 36.8%, P =0.010), and the 2-year OS rate in the CD56⁺ group was higher than that in the CD56^– group, but it didn’t reach statistical significance (74.6% vs 64.9%, P =0.158). The results of univariate Cox regression analysis showed that the PFS was significantly shorter in newly diagnosed MM patients with advanced age, type IgG, high ECOG score, decreased platelet count, increased lactate dehydrogenase level, extramedullary disease, and CD56^– (all P <0.05), the OS was significantly shorter in patients with high ECOG score, decreased platelet count, increased lactate dehydrogenase level, extramedullary disease, and CD56^– (all P <0.05). The results of multivariate Cox regression analysis showed that advanced age, type IgG, elevated lactate dehydrogenase level, extramedullary disease, and CD56^– were independent prognostic factors for poor PFS (all P <0.05); and decreased platelet count, elevated lactate dehydrogenase level, and extramedullary disease were independent adverse prognostic factors for OS (all P <0.05), while there was no significant independent correlation between CD56 and OS (P >0.05).

CONCLUSION: Most of the newly diagnosed MM patients have positive expression of CD56. Loss of CD56 expression was associated with unfavorable biological and clinical parameters and poor prognosis, suggesting that CD56 has important clinical value in the prognosis of newly diagnosed MM patients.

ABSTRACT

OBJECTIVE: To analyze the clinical characteristics of the patients with B-cell chronic lymphoproliferative disease（B-CLPD） in the new drug era and the effect of new drug treatment on efficacy and survival.

METHODS: The clinical and laboratory data of 200 cases B-CLPD patients diagnosed between April 2015 and August 2021 were analyzed retrospectively. The clinical efficacy and survival of the patients under different treatments including Bruton tyrosine kinase（BTK） inhibitors， rituximab， and chemotherapy alone were analyzed. The prognostic factors affecting the survival of patients were analyzed by univarite analysis and multivariate analysis.

RESULTS: There were 119 male（59.5％） and 81 female（40.5%） in 200 cases B-CLPD patients， the sex ratio(male/female) was 1.5∶1 with median age of 61（30- 91） years old. The distribution of subtypes were as fallows: 51 cases (25.5%) of chronic lymphocytic leukemia/small lymphocytic lymphoma（CLL/SLL）， 64（32.0%） cases of follicular lymphoma（FL）， 40（20.0%） cases mantle cell lymphoma（MCL）， 30（15.0%） cases of marginal zone lymphoma（MZL）， 10（5%） cases of lymphoplasmacytic lymphoma/waldenstrom macroglobulinemia（LPL/WM）， 5（2.5%） cases of B cell chronic lymphoproliferative disorders unclassified（B-CLPD-U） . The main clinical manifestation of 102 patients was lymph node enlargement, 32 cases were complicated with B symptoms. Among CLL/SLL patients， there were 12（23.5%） cases in Binet A and 39（76.5%） cases in Binet B/C. There were 29 patients（20.9%） in Ann Arbor or Lugano stage I-II and 110 cases（79.1%） in stage III-IV of other subtypes. The complete remission（CR） rate was 43.1%（25/58）， 40.2%（39/97）， 7.1%（1/14）， and overaIl response rate（ORR） was 87.9%（51/58）， 62.9%（61/97）， 28.6%（4/14） in the groups of BTK inhibitors， rituximab-based therapy， and chemotherapy alone. The 3-year OS rate and PFS rate in all patients was 79.2% and 72.4% respectively. The 3-year OS rate of patient with MZL, CLL/SLL, FL,WM was 94.7%, 87.7%, 86.8% and 83.3% respectively, while the 3-year OS rate of MCL was only 40.6%, which was significantly lower than other subtypes. The median OS of patients treated with BTK inhibitors and rituximab-based therapy was 20.5 and 18.5 months respectively， and the 3-year OS rate was 97.4% and 90.7%. However， the median PFS of patients receiving chemotherapy alone was 4 months， and the 1-year OS rate was 52.7%， which was statistically significant compared with the other two groups（P<0.05）. Univarite analysis showed that anemia， elevated lactate dehydrogenase， elevated β2-microglobulin， and splenomegaly were the poor prognostic factors for OS（P<0.05）， elevated lactate dehydrogenase was also poor prognostic factors for PFS（P<0.05）. Multifactor analysis showed that anemia and elevated lactate dehydrogenase were the independent poor prognostic factors for survival（P<0.05）.

CONCLUSION: The clinical features of B-CLPD was various， anemia and elevated lactate dehydrogenase are the prognostic factors for poor survival. BTK inhibitors and new immunotherapy can improve the survival and prognosis of patients in the new drug era.

ABSTRACT

OBJECTIVE: To investigate the clinical characteristics, therapeutic response and prognosis of patients with plasma cell leukemia (PCL) and improve the understanding of this disease.

METHODS: The clinical manifestations, laboratory tests and treatment response of 27 patients with plasma cell leukemia treated in The Second Hospital of Shanxi Medical University from December 2010 to August 2019 were analyzed retrospectively, and their clinical characteristics were summarized. Kaplan-Meier method was used for survival analysis.

RESULTS: There were 18 cases of primary plasma cell leukemia (pPCL) and 9 cases of secondary plasma cell leukemia (sPCL). The male to female ratio was 1.7∶1. The median age was 62 years old. The first manifestations were bone pain, fatigue, fever, splenomegaly and bleeding, and a large number of plasma cell infiltration was observed in the morphological examination of peripheral blood and bone marrow cells. 13 cases were detected by immunotyping and all of them expressed CD38/CD138. 8 cases underwent karyotype analysis, and 3 cases were normal, clonal abnormalities occurred in 5 cases. FISH detection was performed in 12 cases, of which 8 cases were abnormal. In 17 cases of bortezomib based chemotherapy, the ovevall response rate was 52.9%, which was higher than that in the non-bortezomib group, but there was no significant difference between the two groups (P =0.242). The overall median survival time of 27 patients was 6.4 months, the median progression-free survival time was 3.5 months, and the median survival time of patients with pPCL and sPCL was 8.2 months and 2.4 months, respectively, the difference between the two groups was statistically significant (P =0.031).

CONCLUSION: PCL is highly invasive and has diverse clinical manifestations, and is not sensitive to traditional chemotherapy. The median survival time of patients with pPCL is relatively longer than that of patients with sPCL. The chemotherapy regimen based on bortezomib improves the treatment effectiveness and prolongs the survival time of PCL patients.

ABSTRACT

OBJECTIVE: To investigate the expression and significance of regulatory T cells (Tregs), FoxP3 and transforming growth factor-β (TGF-β) in different phase of chronic myeloid leukemia (CML).

METHODS: Peripheral blood of 73 CML patients in Department of Hematology, Heze Municipal Hospital from March 2018 to March 2021 were collected. According to patient’s period in CML, they were divided into ND CML group (newly diagnosed), CP CML group (chronic period), and BP CML group (blast phase). The percentage of Tregs, expression level of FoxP3 mRNA and TGF-β were detected by flow cytometry, RT-qPCR, and ELISA, respecitively. The roles of above indices in clinical pathogenesis of patients with CML were analyzed.

RESULTS: The proportion of Treg in the ND CML group was slightly higher than the CP CML group, but the difference was not statistically significant (P =0.695), while the BP CML group was significantly higher than the other two groups (P =0.008, P <0.001). The expression levels of FoxP3 mRNA in ND CML group, CP CML group and BP CML group were 11.61±2.21, 6.46±1.35 and 8.54±2.13, respectively. Significant difference in FoxP3 mRNA levels was observed among patients in different phases of CML (F =55.199, P <0.001). The expression levels of FoxP3 mRNA both in ND CML group and BP CML group were significantly higher than that in CP CML group (P <0.001), and the ND CML group was the highest (P <0.001). However, the expression levels of TGF-β in different phases of CML showed no statistical differences (H =0.634, P =0.728).

CONCLUSION: The abnormal distribution of Treg subset in different phases of CML and the significant increase of the expression level of FoxP3 mRNA in the new onset and blast phase of CML suggest that Tregs may promote the occurrence and progression of CML through immune regulation.

ABSTRACT

OBJECTIVE: To study the cerebrospinal fluid (CSF) status and prognosis value in patients with newly diagnosed acute lymphoblastic leukemia (ALL) by flow cytometry (FCM).

METHODS: The clinical features of the 75 newly diagnosed ALL patients from September 2020 to December 2021 in our centre were retrospective analyzed, as well as the bone marrow (BM) and CSF minimal residual disease (MRD) data, and the CSF conventional cytology data. Central nervous system infiltration(CNSI) positive was as CSF MRD positive by FCM or leukemia cells detected by conventional cytology. The status of CSF were compared and analyzed by FCM and conventional cytology, the clinical features and the prognosis value of different CNSI status in these patients were analyzed.

RESULTS: Among 75 newly diagnosed ALL, 16 cases (21%) with CNSI positive (CNSI⁺) were detected by FCM, while only 2 positive cases (3%) were detected by conventional cytology. The CNSI⁺ rate detected by FCM was significantly higher than conventional cytology(P<0.05). Compared with CNSI^– ALL patients, the median age of CNSI⁺ ALL patients was significantly younger, and the median platelet count was significantly lower, the difference was statistically significant (P<0.05). Up to follow-up time (August 31, 2022), four ALL patients were died, including 3 patients were CNSI^– and 1 patient was CNSI⁺. Furthermore, three cases were primary disease relapse, including 1 case was CNSI⁺. There was no significant difference in overall survival (OS) rate and relapse-free survival (RFS) rate of the patients with different CNSI status.

CONCLUSION: Compared with conventional cytology, FCM is a more sensitive assay to evaluate the central nervous system status in ALL patients. After active treatment, there was no significant difference in OS and RFS between patients with different CNSI status at diagnosis.
