Early predictor for differentiation syndrome in newly diagnosed acute promyelocytic leukaemia patients treated with single-agent arsenic trioxide.

Differentiation syndrome (DS) is the second leading cause of death in acute promyelocytic leukaemia (APL) patients. Few studies have tested predictors of DS events. This study aimed to identify optimized predictors of DS events related to APL. The data of 298 consecutive patients who were newly diagnosed with APL between December 2012 and June 2023 were retrospectively investigated. A systematic review of computer-based patient medical records was conducted to obtain clinical data, including baseline characteristics, routine blood examination findings, biochemical indices and clinical manifestations of DS. Among the 298 patients, 158 were classified into the no-DS group, while 140 had DS. Compared with those of patients without DS, the peripheral blast count, age, and WBC count at each time point were significantly different in patients with DS (P < 0.05 for all time points). Generalized linear mixed models (GLMMs) revealed that WBC Double (Coeff. 0.442, P = 0.000) and WBCPeak (Coeff. 0.879, P = 0.000) were independent risk factors for DS. The frequencies of clinical manifestations of unexplained fever (P = 0.003), dyspnoea (P = 0.002), weight gain of more than 5 kg (P = 0.006), pleural effusion (P = 0.001), pulmonary infiltrates (P < 0.001), pericardial effusion (P = 0.002) and renal failure (P = 0.006) were considerably lower in moderate DS patients than in severe DS patients. The WBCDouble occurs earlier than the WBCpeak occurrence, so WBC Double might be a new indicator of DS.

[Effect of Circulating Plasma Cells on the Prognosis of Patients with Multiple Myeloma].

OBJECTIVE: to analyze the effect of circulating plasma cells(CPC) on the prognosis of patients with multiple myeloma(MM) in the era of new drugs, and to explore the new definition standard of primary plasma cell leukemia(pPCL). METHODS: The clinical data of 321 patients with newly diagnosed MM and 21 patients with pPCL admitted to our hospital from January 2014 to May 2022 were retrospectively analyzed. According to the proportion of CPC in peripheral blood smears, all patients were divided into 4 groups: CPC 0% group(211 cases), CPC 1%-4% group(69 cases), CPC 5%-19% group(41 cases) and CPC≥20% group(21 cases). The clinical features of patients in each group were compared and the prognosis fators was analyzed. RESULTS: The median OS of the four groups were 44.5,21.3,24.6 and 12.8 months, respectively. Among them, 295 patients(86.3%) were treated with new drugs, and the median OS of the four groups were not reached, 26.7, 24.6 and 14.9 months, respectively. As the survival curves of CPC 5%-19% group and CPC≥20% group were similar, the patients were divided into CPC<5% group and CPC≥5% group, the median OS of CPC<5% group was better than that in CPC≥5% (43.5 vs 22.3 months, P<0.001). In addition, the median OS of patients in the CPC 1%-4% group was also significantly lower than that in the CPC 0% group and similar to that in the CPC≥5% group. Multivariate analysis showed that 1%-4% CPC was an independent risk factor for the OS of patients with CPC<5%. The patients with CPC<5% were stratified by R-ISS staging, and the OS of R-ISS stage Ⅰ or stage Ⅱ with 1%-4% CPC was similar to that of R-ISS stage Ⅲ. The newly defined pPCL patients showed increased tumor load and obvious invasive characteristics. Multivariate analysis showed no independent prognostic factors for pPCL, and high-risk cytogenetic abnormalities(HRCA) had no significant effect on the prognosis. CONCLUSION: The validity of IMWG's new pPCL definition standard was verified, and it was found that the survival of MM with 1%-4% CPC also is poor and the prognosis is very close to pPCL. In addition, the newly defined pPCL has unique clinical and biological characteristics.

Serum Human Epididymis Protein 4 Combined with Carbohydrate Antigen 125 for Endometrial Carcinoma Diagnosis: A Meta-Analysis and Systematic Review.

Objective: To evaluate the overall diagnostic value of human epididymis protein 4 (HE4) combined with carbohydrate antigen 125 (CA125) in endometrial carcinoma (EC) based on a meta-analysis of all eligible studies. Methods: The PubMed, Cochrane, Embase, CNKI, VANFUN, and VIP databases were searched by index words to identify eligible studies and also to search for relevant literature sources that had been published by January 2019. Eligible studies included prospective cohort studies or cross-sectional studies. The heterogeneity of the included studies was used to select appropriate effect models to calculate summary weighted sensitivity, specificity, and diagnostic odds ratios (DORs). The summary receiver operational characteristic (SROC) analysis was summarized for the EC. Results: In total, 25 studies that had explored the diagnostic accuracy of HE4 combined with CA125 for EC were included in this meta-analysis. Nine were from English language articles and 16 from Chinese language articles. The global sensitivity and specificity of HE4 combined with CA125 for EC were as follows: 66% (95% CI: 60-72) and 92% (95% CI: 88-95), respectively. The global positive likelihood ratio and global negative likelihood ratio of HE4 combined with CA125 for EC were as follows: 8.03 (95% CI: 5.36-12.04) and 0.37 (95% CI: 0.31-0.44), respectively. The global DOR was19.59 (95% CI: 12.25-31.32) for IL-6. The area under the SROC was high for HE4 combined with CA125 (AUC = 0.86; 95% CI: 0.83-0.89). Conclusion: This study provides a systematic review and meta-analysis of the diagnostic accuracy of HE4 combined with CA125 for EC. The results indicate that HE4 combined with CA125 is highly accurate for the diagnosis of EC.

Psychometric properties of the Chinese version of the Functioning Assessment Short Test (FAST) in bipolar disorder.

OBJECTIVES: Bipolar disorder (BD) is often associated with significant functional impairment. However, there is currently no valid and reliable instrument for this variable that is both brief and easy to administer in China. We thus aimed to evaluate the psychometric properties of the Chinese version of the Functioning Assessment Short Test (FAST) in Chinese adults with BD. METHODS: In this sample of adult subjects, 176 with BD and 53 healthy controls were included. The Chinese version of the FAST, the Young Mania Rating Scale (YMRS), the 17-item Hamilton Depression Rating Scale (HDRS-17) and the Global Assessment Functioning (GAF) were administered, and the psychometric analysis of the FAST was conducted. RESULTS: The internal consistency (Cronbach's alpha) was 0.89 and 0.88 for the FAST at the baseline and week 1, respectively. Four domains (occupational functioning, cognitive functioning, interpersonal relationship and financial issues) at baseline had high item-total correlations. The FAST assessments at baseline and week 1 were highly correlated, indicating high test-retest reliability. The FAST total score was strongly associated with GAF total scores at week 0 (r  = -0.952, p < 0.001), HDRS (r = 0.575, p < 0.001) and YRMS (r = 0.394, p < 0.001) and at week 1 (r  = -0.945, p < 0.001; r  = 0.582, p < 0.001; r  = 0.363, p < 0.001), respectively, suggesting high concurrent validity. The FAST showed four dimensional measurement properties in exploratory factor analysis at baseline. CONCLUSIONS: The Chinese version of the FAST has satisfactory psychometric properties in terms of validity and reliability in Chinese adults with BD.
