Clinical Outcomes In Chinese Patients Research Articles

Real-world clinical outcomes in Chinese patients with EGFR-mutated NSCLC progressed from first-line EGFR-TKI: A prospective multicenter study.

e20547 Background: EGFR-TKIs is standard of care for treatment-naïve EGFR mutated ( EGFRm) advanced NSCLC (aNSCLC). The clinical outcome after 1L EGFR-TKI in clinical practice is not well studied prospectively. Herein, we reported the real-world clinical outcomes in Chinese EGFRm aNSCLC progressed from 1L EGFR-TKI. Methods: This prospective, observational study enrolled 300 Chinese patients (pts) from 16 sites between March, 2020 and August, 2021. At data cut-off date of August 27, 2023. 291 eligible pts were included into the full analysis set (FAS) and 225 pts in FAS received second-line EGFR-TKI or chemotherapy were included into outcome analysis set (OAS). The clinical outcome (PFS and OS, measured from 2nd line treatment) were presented. Results: The median age of 291 pts in FAS was 62 years, 57.0% was females and 29.3% pts with brain metastasis. EGFR mutation included 19del (143 pts, 49.1%), L858R (126 pts, 43.3%) and others (22 pts, 7.6%). 273 (93.8%) and 18 (6.2%) pts progressed from 1L 1G/2G EGFR-TKIs and 3G EGFR-TKIs, respectively. In OAS, overall mPFS and mOS in T790M + patients (90 pts) who received 2L 3G EGFR-TKIs were 14.7 (10.40-18.0) and 32 (25.20-NE) months, respectively. The mPFS and mOS by type of sample and T790M test results were presented in table. 85 pts with T790M- who progressed from 1L 1/2G EGFR-TKIs, including 51, 9 and 25 pts received 3G EGFR-TKIs, prior EGFR-TKIs plus local therapy, and chemotherapy as 2L therapy, respectively. The corresponding mPFS were 7.60 (95% CI, 4.70-10.40), 10.20 (2.30-14.90), and 4.90 (2.50-6.90) months, respectively. The corresponding mOS were 21.20 (12.10-NE), 16.60 (6.00-28.60), and 15.00 (9.40-NE) months, respectively. For T790M- patients with 19del (21 pts) and L858R (26 pts) mutation who received 2L 3G EGFR-TKIs, the mPFS was 21.00 (2.60-NE), and 8.00 (5.00-10.40) months, respectively. mOS was NE (21.00-NE) and 16.60 (8.20-24.60) months, respectively. 12 pts progressed from 1L 3G EGFR-TKIs, 10 and 2 pts received chemotherapy-based regimen and prior EGFR-TKIs plus local therapy as 2L therapy, respectively. The corresponding overall mPFS were 8.40 (95% CI: 1.20-11.80) months. The overall mOS was 14.20 (2.80-NE) months. Conclusions: The real-world treatment pattern and corresponding prognosis of EGFR-mutated NSCLC progressed from first-line EGFR-TKI were diverse, and among them those who received 3G EGFR-TKI at progression showed a better clinical outcome. These results supplemented the clinical evidence for the use of 3G EGFR-TKIs in EGFRm aNSCLC pts who progressed from 1L 1/2G EGFR-TKIs in the real-world setting.

Associations of comorbid depression with cardiovascular-renal events and all-cause mortality accounting for patient reported outcomes in individuals with type 2 diabetes: a 6-year prospective analysis of the Hong Kong Diabetes Register.

Psychosocial status and patient reported outcomes (PRO) [depression and health-related quality-of-life (HRQoL)] are major health determinants. We investigated the association between depression and clinical outcomes in Chinese patients with type 2 diabetes (T2D), adjusted for PRO. Using prospective data from Hong Kong Diabetes Register (2013-2019), we estimated the hazard-ratio (HR, 95%CI) of depression (validated Patient Health Questionnaire 9 (PHQ-9) score≥7) with incident cardiovascular disease (CVD), ischemic heart disease (IHD), chronic kidney disease (CKD: eGFR<60 ml/min/1.73m2) and all-cause mortality in 4525 Chinese patients with T2D adjusted for patient characteristics, renal function, medications, self-care and HRQoL domains (mobility, self-care, usual activities, pain/discomfort, anxiety/depression measured by EQ-5D-3L) in linear-regression models. In this cohort without prior events [mean ± SD age:55.7 ± 10.6, 43.7% women, median (IQR) disease duration of 7.0 (2.0-13.0) years, HbA1c, 7.2% (6.6%-8.20%), 26.4% insulin-treated], 537(11.9%) patients had depressive symptoms and 1923 (42.5%) patients had some problems with HRQoL at baseline. After 5.6(IQR: 4.4-6.2) years, 141 patients (3.1%) died, 533(11.8%) developed CKD and 164(3.6%) developed CVD. In a fully-adjusted model (model 4) including self-care and HRQoL, the aHR of depression was 1.99 (95% confidence interval CI):1.25-3.18) for CVD, 2.29 (1.25-4.21) for IHD. Depression was associated with all-cause mortality in models 1-3 adjusted for demographics, clinical characteristics and self-care, but was attenuated after adjusting for HRQoL (model 4- 1.54; 95%CI: 0.91-2.60), though HR still indicated same direction with important magnitude. Patients who reported having regular exercise (3-4 times per week) had reduced aHR of CKD [0.61 (0.41-0.89)]. Item 4 of PHQ-9 (feeling tired, little energy) was independently associated with all-cause mortality with aHR of 1.66 (1.30-2.12). Depression exhibits significant association with CVD, IHD, and all-cause mortality in patients with diabetes, adjusting for their HRQoL and health behaviors. Despite the association between depression and all-cause mortality attenuated after adjusting for HRQoL, the effect size remains substantial. The feeling of tiredness or having little energy, as assessed by item Q4 of the PHQ-9 questionnaire, was found to be significantly associated with an increased risk of all-cause mortality after covariate adjustments. Our findings emphasize the importance of incorporating psychiatric evaluations into holistic diabetes management.

Efficacy and Safety of Asciminib in Chinese Patients with Philadelphia Chromosome(Ph)-Positive Leukaemias

Background Asciminib is a first-in-class STAMP (Specifically Targeting the ABL Myristoyl Pocket) tyrosine kinase inhibitor (TKI). Its efficacy and safety profile in patients with chronic-phase chronic myeloid leukaemia (CML) have been shown in the Phase 3 ASCEMBL study, comparing asciminib 40 mg twice daily versus bosutinib 500 mg once daily. However, asciminib use in Chinese patients has hitherto not been reported. Moreover, the safety of high-dose asciminib (≥150 mg twice daily) in the Asian population is yet to be addressed. Here we present the real-world clinical outcomes of Chinese patients with Ph+ leukaemias in Hong Kong who received asciminib through a Managed Access Program (MAP). Methods Queen Mary Hospital (QMH) is a university-affiliated tertiary hospital in Hong Kong. Patients with Ph+ leukaemias under the care of QMH for whom asciminib was requested through MAP were included. Details on patient demographics, disease history, prior treatment lines, asciminib usage, adverse events, efficacy and death were collected. Results At data cut-off for analysis on 30 June 2023, 13 patients for whom asciminib was approved had data available. One patient passed away before the commencement of asciminib, and thus was excluded (Table 1). There were 7 patients with CML, who on diagnosis were all in chronic phase at a median age of 53 (22-70) years. All had received imatinib and at least one newer generation TKI, with 5 patients (71%) having received ponatinib. The majority (5 patients, 71%) received asciminib because of lack of efficacy of prior treatment, with 4 patients also having the T315I mutation. The median age at asciminib treatment (median dose: 400 mg, 80-400 mg) was 64 (28-76) years, with a median time from diagnosis of 81 (13-314) months. Two patients received imatinib concomitantly. The median duration of treatment was 12 (6-38) months. Two patients were already in at least major molecular response (MMR) before treatment, and have maintained that response. Two patients had ≥ 1-log reduction of BCR::ABL1 transcript level. Three patients had stable disease. There was one death unrelated to CML (Figure 1). There were 5 patients with Ph-positive acute lymphoblastic leukaemia (ALL), at a median age of 57 (18-68) years at diagnosis. All had received prior chemotherapy in combination with a TKI (imatinib, N=3; dasatinib, N=5; ponatinib, N=5), with 3 patients having undergone allogeneic haematopoietic stem cell transplantation (allo-HSCT). Three patients had detectable kinase domain mutation (T315I, N=2; E255K + E459K, N=1). The majority (3 patients, 60%) received asciminib because of lack of efficacy of prior treatment. The median age at asciminib treatment (median dose: 240 mg, 80-400 mg) was 58 (19-72) years, with a median time from diagnosis of 22 (7-47) months. The median duration of treatment was 16 (2-19) months. Four patients received another ATP-competitive TKI concomitantly (imatinib, N=1; dasatinib, N=1; ponatinib, N=2). For patients receiving asciminib due to prior treatment failure (N=3), complete molecular response (CMR) was achieved in 2 patients with measurable residual BCR:: ABL1; 1 patient with frank leukaemia achieved complete remission with incomplete hematologic recovery with molecular response at 0.06%. For two patients receiving asciminib because of intolerance to prior treatment, one further improved from MR4 to CMR while pre-existing CMR was maintained in the other patient. There were 3 deaths; 2 due to COVID-19 and 1 due to refractory leukaemia (Figure 1). Asciminib showed an acceptable safety profile, with raised lipase leading to dose reduction only in 1 patient. Grade 3 or above toxicities were all haematological, observed in 5 patients, 2 of whom had previous allo-HSCT. One patient on asciminib-ponatinib treatment developed grade 2 renal impairment. Conclusion Asciminib demonstrated promising clinical efficacy with satisfactory tolerance in this cohort of Ph+ leukaemias failing multiple lines of therapy. Further investigation of its therapeutic role in Ph+ ALL is warranted.

Prediction Score for Clinical Outcome of Chinese Patients with Cerebral Venous Thrombosis.

Although numerous prognostic markers for cerebral venous thrombosis (CVT) have been reported, inconsistencies exist in their predictive values, leading to contradictory forecasts. This study was designed to develop a comprehensive clinical outcome prediction score for Chinese patients with CVT, integrating key prognostic markers to furnish an overall prognosis. Participants were selected from the CCC cohort, a multicenter study encompassing 26 tertiary hospitals across mainland China. Between January 2021 and May 2022, 170 patients with CVT were prospectively recruited. Potential prognostic markers were extracted from the CCC database and subsequently analyzed. Age, diastolic blood pressure (DBP), neutrophil-to-lymphocyte ratio (NLR), and neuron-specific enolase (NSE) emerged as significant prognostic markers for CVT after a multivariate logistic analysis. Specific cut-off values were identified: Age > 27.5 years, DBP > 79.5 mmHg, NLR > 6.6, and NSE >16.5 ng/mL. The points assigned were: one each for age and NSE level, two for DBP, and three for NLR, based on the adjusted odds ratio. A positive correlation was found between the baseline CVT outcome score and the mRS at six months' follow-up. A CVT outcome score of 3.5 served as an effective cut-off value for predicting CVT clinical outcomes. Further analysis revealed that patients with CVT outcome scores > 3 exhibited significantly higher mRS scores than those with scores ≤ 3. This study led to the development of the CVT outcome score, consisting of age, DBP, NLR, and NSE level, specifically for Chinese patients with CVT. The baseline CVT outcome score positively correlated with the mRS score at the six-month follow-up. A CVT outcome score of > 3 serves as a reliable indicator to identify patients at a higher risk of unfavorable clinical outcomes. These patients may benefit from additional care and early interventions to avert potential deterioration.

Performance of DAPT Score and ESC Criteria for Predicting Clinical Outcomes in Chinese Patients with Acute Coronary Syndrome.

The values of European Society of Cardiology (ESC) criteria and dual antiplatelet therapy (DAPT) score in the stratification of ischemic risk were assessed in this study. A total of 489 patients with acute coronary syndrome who received DAPT at discharge between June 2020 and August 2020 were enrolled. The primary endpoint was the occurrence of major adverse cardiovascular events (MACE), which included recurrent ACS or unplanned revascularization, all-cause death, or ischemic stroke during a 27-month follow-up period. Patients with ESC-defined high-risk showed a significantly higher risk of MACE (HR 2.75, 95% CI 1.78-4.25), all-cause death (HR 2.49, 95% CI 1.14-5.43), and recurrent ACS or unplanned revascularization (HR 2.80, 95% CI 1.57-4.99) than those with ESC-defined low/medium-risk during follow-up. The results of landmark analysis showed that patients in the high-risk group had a significantly higher risk of MACE (HR 2.80,95 CI% 1.57-4.97), recurrent ACS or unplanned revascularization (HR 3.19,95 CI% 1.47-6.93) within one year, and a higher risk of MACE (HR 2.69,95 CI% 1.38-5.23) after one year. There was no significant difference in the incidence of MACE between patients with a DAPT score ≥2 and a DAPT score <2. The C-indices of ESC criteria and DAPT score for prediction of MACE were 0.63 (95% CI 0.57-0.70) and 0.54 (95% CI 0.48-0.61), respectively. The predictive value of ESC criteria for MACE was better than the DAPT score according to the DeLong test (z-statistic=2.30, P=0.020). Patients with ESC-defined high-risk had a higher risk of MACE compared to those with ESC-defined low/medium-risk. The discriminant ability of the ESC criteria was better than the DAPT score for MACE. The ESC criteria demonstrated moderate discriminatory capacity of MACE in ACS patients treated with DAPT.

Clinical outcomes of patients with metastatic breast cancer treated with eribulin: A real-world evidence study from China.

e13126 Background: Eribulin is a novel synthetic analog of halichondrin B that acts as a microtubule inhibitor and inhibits the G2-M growth phase. Eribulin was approved for metastatic breast cancer (MBC) based on the landmark phase 3 EMBRACE trial (Cortes et al, Lancet 2011; NCT00388726); however, only a small number of Asian patients were included in that trial. Therefore, in this real-world study, we retrospectively assessed the clinical outcomes of Chinese patients with MBC who received eribulin. Methods: Adult patients with MBC who received eribulin as several lines of therapy were retrospectively analyzed. Socio-demographic, clinical, pathology, imaging, and therapy records were reviewed. Progression-free survival (PFS) and tumor response were evaluated. Results: A total of 85 patients were included. The median age was 45 years (range, 21–63). Eribulin was used as a first, second, third, and fourth or more chemotherapy agent in 13 (15.3%), 16 (18.8%), 11 (12.9%) and 45 (52.9%) of patients with MBC, respectively. Eribulin was monotherapy in 32.9% of patients; eribulin plus anti-HER2 targeted therapy was used in 9.4% of patients; eribulin plus immunotherapy was used in 5.9% of patients; eribulin plus other chemotherapy was used in 36.5% of patients, and eribulin plus antiangiogenic therapy was used in 9.4% of patients. The objective response rate (ORR) was 28.2% overall. By number of lines of therapy, the first-line ORR was 38.5% and the second-line ORR was 37.5%. On subgroup analysis, ORR of patients with liver metastasis and lung metastasis was 43.9% and 38.6 %, respectively. By molecular classification, the ORR of patients with HR+/HER2− disease was 66.7%; among patients with HER2+ disease, 32.6%; and among patients with triple-negative BC, 13.3%. The 6-month PFS rate was 33.6% overall. By number of lines of therapy, the 6-month PFS rate among patients who received eribulin as first-line treatment was 67.7% and among patients who received eribulin as second-line treatment, 38.3%. Among patients who received eribulin monotherapy, the 6-month PFS rate was 21.4% and among patients who received eribulin combination therapy, 41.2%. No adverse reactions related to neutrophils were reported. Conclusions: This real-world retrospective study suggests that eribulin was effective in Chinese patients with MBC with a range of prior lines of chemotherapy, supporting the use of eribulin in the treatment of Chinese patients with MBC.

17th International Conference on Malignant Lymphoma, Palazzo dei Congressi, Lugano, Switzerland, 13 - 17 June, 2023.

Background: Axi-cel was approved by NMPA to treat R/R LBCL adult patients who had received 2 or more prior treatments in 2021 June. For better understanding the efficacy and safety of commercial Axi-cel in Chinese R/R NHL patients in real world setting, we conducted this multi-center, non-interventional study (ChiCTR2100047990). The accrual goal is 200 patients, and the primary endpoint is median OS. Here we made an interim analysis and reported clinical outcomes of Chinese patients treated by commercial CAR-T products in real world for the first time. Methods: R/R NHL patients treated with commercial Axi-cel in 17 authorized treatment centers from 11/2021 to 02/2023 were included. All patients signed written informed consents. We reported best objective response rate (bORR), best complete response (bCR) rate and adverse events. Results: A total of 101 R/R NHL patients were efficacy-evaluable. The median age was 56.8 years old, and 25 (24.8%) patients were ≥65 years. Fifty-nine patients were male. Baseline characteristics, including 80 (79.2%) with DLBCL, 4 (4.0%) with PMBCL, and 6 (5.9%) with high grade B-cell lymphoma. Forty-two (44.2%) patients had IPI ≥3 and 18 (24.3%) patients ECOG PS were ≥2. The median prior lines of therapy was 2, including 36 (35.6%) patients got ≥3 previous treatments and 10 patients had history of ASCT. Eighty-four patients were resistant to previous therapy, and the primary refractory subgroup reached 47 (46.5%). Bridging therapy was given in 56 (55.4%) patients, while combination therapy in 29 (28.7%) patients. The median follow-up was 9.2 months. The bORR and bCR was 83.2% (95% CI, 74.4 to 89.9) and 58.4% (95% CI, 48.2 to 68.1) respectively (Figure 1A). Response rates were consistent across key covariates, including disease type, disease stage, IPI score, cell-of-origin subtype, etc. Patients ≥65 years had favorable ORR [92.0% (95% CI, 74.0–99.0)] and CR rate [80.0% (95% CI, 59.3–93.2)]. Median PFS was 12.0 months (95% CI, 7.3 to NA). The median DOR and OS were not reached. No new safety signal was observed in Chinese patients. The most common ≥ grade 3AE were white-cell count decreased (in 87.6% of the patients), neutropenia (in 82.9%), pyrexia (in 73.3%). Eighty-one patients experienced cytokine release syndrome (CRS) of any grade, and 16 (15.2%) patients occurred grade 3 or higher. Any grade of neurologic events (NE) occurred in 17 (16.2%) patients, and only 1 (1.0%) patients were grade 4. No grade 5 CRS or NE appeared (Figure 1B-C). Fifty-five percent received tocilizumab and 52% received glucocorticoids to manage CRS and/or NE. The median cumulative cortisone-equivalent corticosteroid dose was 2000 mg, which was similar to ZUMA-1 cohort6 and much smaller than ZUMA-1 cohort1+2.

Impact of primary tumor side on clinical outcomes of first-line cetuximab plus FOLFOX-4 in RAS wild-type metastatic colorectal cancer.

Aim: To examine the impact of tumor sidedness on clinical outcomes in Chinese patients with metastatic colorectal cancer treated with folinic acid/fluorouracil/oxaliplatin (FOLFOX-4)±cetuximab in the TAILOR trial. Patients & methods: Clinical data from 391 patients were evaluated for tumor sidedness. Results: Patients with left-sided tumors who received cetuximab plus FOLFOX-4 had a significantly longer overall survival (medians: 22.0 vs 18.3months; p=0.007) and progression-free survival (medians: 9.3 vs 7.9months; p=0.006) compared with FOLFOX-4 alone. Overall survival (medians: 11.5 vs 9.4months; p=0.664) and progression-free survival (medians: 7.4 vs 4.5months; p=0.068) also improved in patients with right-sided tumors. Conclusion: Adding cetuximab to first-line FOLFOX-4 in patients with metastatic colorectal cancer improved clinical outcomes irrespective of primary tumor side.

Clinical outcomes following discontinuation of renin-angiotensin-system inhibitors in patients with type 2 diabetes and advanced chronic kidney disease: A prospective cohort study.

Renin-angiotensin-system inhibitors (RASi), that include angiotensin converting enzyme inhibitors (ACEis) and angiotensin receptor blockers (ARBs) reduce proteinuria, delay chronic kidney disease (CKD) progression, protect against cardiovascular events and heart failure hospitalizations. We examined the associations of discontinuation of ACEi/ARBs with risk of clinical outcomes in Chinese patients with type 2 diabetes (T2D) and advanced-CKD (estimated-glomerular filtration rate [eGFR] <30ml/min/1.73m2). We conducted a prospective, population-based cohort study including 10,400 patients with T2D in Hong Kong stratified by continuation of ACEi/ARBs within 6 months after reaching eGFR <30ml/min/1.73m2 from January 01, 2002 to December 31, 2018 and observed until December 31, 2019. The primary outcomes were death, major-adverse cardiovascular events (MACE), heart failure, end-stage kidney disease (ESKD), and all-cause mortality. Cox-model with time-dependent exposure and covariates was used to estimate the hazard ratio (HR) of outcomes in a propensity-score overlap-weighted cohort. The risk of occurrence of hyperkalemia (plasma potassium >5.5mmol/L) in discontinued-ACEi/ARBs versus continued-ACEi/ARBs users was assessed in a register-based cohort. In the population-based cohort of 10,400 ACEi/ARBs users with new-onset eGFR<30ml/min/1.73m2, 1766 (17.0%) discontinued ACEi/ARBs and 8634 (83.0%) persisted with treatment. During a median follow-up of 3.6 (interquartile range, IQR: 2.11-5.8) years (41,623 person-years), 13.5%, 12.9%, and 27.6% had incident MACE, heart failure and ESKD respectively, and 35.8% died. Discontinued-ACEi/ARBs use was associated with higher risk of MACE (HR=1.27, 95% CI: 1.08-1.49), heart failure (HR=1.85, 95% CI: 1.53-2.25) and ESKD (HR=1.30, 95% CI: 1.17-1.43), and neutral risk of all-cause mortality (HR=0.93, 95% CI: 0.86-1.01) compared to counterparts with continued use. In the register-based cohort (583 discontinued-ACEi/ARBs users and 3817 continued-ACEi/ARBs users), discontinued-ACEi/ARBs had neutral risk of hyperkalemia (HR=0.95, 95% CI: 0.84-1.08). Discontinuation of ACEi/ARBs was associated with increased risk of cardiovascular-renal events supporting their continued use in patients with T2D and advanced-CKD.

The MODIFY Study Protocol: An Open-Label, Single-Arm, Multicenter, Prospective Pragmatic Study of Ixazomib-Based Triple-Drug Therapy in Chinese Patients with Multiple Myeloma.

Although the bortezomib-based triple-drug therapy is considered as a front-line therapy for multiple myeloma (MM) in Chinese patients, increased level of toxicity leads to treatment dissatisfaction. Treatment with ixazomib, an oral proteasome inhibitor, has demonstrated better efficacy and safety profile without increasing the toxicity. In this study, we investigate the safety and clinical outcomes of Chinese patients with newly diagnosed MM (NDMM) who transitioned from a bortezomib-based triple-drug therapy to an ixazomib-based triple-drug therapy in a real-world clinical setting. This will be an open-label, single-arm, multicenter, prospective, observational study will recruit Chinese patients (aged ≥ 18years) diagnosed with NDMM using International Myeloma Working Group (IMWG) criteria and who have received a bortezomib-based triple-drug therapy for more than two cycles as initial therapy. The previous bortezomib-based triple-drug therapy may include bortezomib, cyclophosphamide, and dexamethasone or lenalidomide, bortezomib, and dexamethasone or bortezomib, doxorubicin, and dexamethasone or bortezomib, thalidomide, and dexamethasone. At the time of enrollment, patients must have achieved at least partial response as defined by IMWG criteria. Approximately 320 eligible patients at 15 top MM hospitals in China will be treated with ixazomib triple-drug therapy and followed up once every 3months for 24months, unless specified. The primary endpoint is to assess progression-free survival at 2years for Chinese patients with NDMM who have transitioned from a bortezomib-based triple-drug therapy to ixazomib-based triple-drug therapy. The clinical effectiveness, safety and tolerability, patient-reported outcomes, and health economic/resource utilization will be evaluated as secondary endpoints. The results from this study may provide evidence to verify the benefits of transitioning from bortezomib-based triple-drug therapy to ixazomib-based triple-drug therapy in Chinese patients with NDMM in a real-world clinical setting. The study has been registered at clinicalTrials.gov (NCT05013190).

Validation of plasma D-dimer in Chinese patients with acute non-ST segment elevation myocardial infarction.

To analyze the predictive values of D-dimer in Chinese patients with non-ST-segment elevation myocardial infarction (NSTEMI). We retrospectively retrieved consecutive patients hospitalized due to acute NSTEMI from January 2015 to December 2018 from the Electronic Medical Record (EMR) library. Clinical and follow-up data were collected. The primary endpoint was major adverse composite cardiovascular events (MACEs), such as all-cause death, non-fatal myocardial infarction, and non-fatal stroke. The secondary endpoints included all-cause death, non-fatal myocardial infarction, non-fatal stroke, heart failure, and severe arrhythmias. The Cox regression model was used to evaluate the association between risk factors and clinical outcomes in Chinese patients with NSTEMI. A total of 673 patients were included; the median age was 64.0 (53.0-75.0) years old and 76.2% were men. Patients with higher D-dimer levels were more often women, older, had a higher Charlson Comorbidity Index, and had a higher incidence of MACEs (59.9 vs. control 9.0%; p < 0.001) and all-cause death (49.1 vs. control 2.2%; p < 0.001). The multivariate Cox analysis suggested that the D-dimer level was an independent predictor of MACEs (hazard ratio [HR]: 1.069, 95% CI: 1.010-1.132, p = 0.021). The receiver operating characteristic (ROC) analysis suggested that D-dimer levels were better than the Charlson Comorbidity Index in all-cause death. In Chinese patients with acute NSTEMI, higher D-dimer levels on admission suggest a poor long-term prognosis.

Clinical features and outcomes of patients with follicular lymphoma: A real-world study of 926 patients in China.

BackgroundThe data about the clinical features and outcomes of Chinese patients with follicular lymphoma (FL) are limited. Here, we conducted a retrospective study to explore the initial treatment strategies and clinical outcomes of Chinese patients with FL in the real world.MethodThis study included FL patients who were newly diagnosed in Tianjin Medical University Cancer Institute and Hospital from March 2002 to August 2020.ResultsA total of 926 FL patients were enrolled. The median age was 54 years old, and the majority of the Chinese FL patients had advanced-stage disease and Eastern Cooperative Oncology Group(ECOG) <1 but less frequently infiltrated bone marrow. After a median of 38-month follow-up, the 5-year progressive-free survival (PFS) and overall survival (OS) of grade1–3a were 57.8% and 88.7%, respectively, which both are similar to those reported in previous Chinese and Western studies. The co-existence at diagnosis of FL and diffuse large B-cell lymphoma (DLBCL) components (FL/DLBCL) was associated with poor outcomes. The FL grades and proportion of DLBCL component in FL/DLBCL did not have an impact on PFS and OS. The most common regimen with great efficacy and risk–benefit was RCHOP-like followed by R maintenance regimen. The 5-year cumulative hazard of histological transformation (HT) was 4.7% (95% CI, 3.5–5.9); median time to transformation was 23.5 months (range, 2–146 months) after diagnosis. Three-year survival following transformation was 55% (95% CI, 40–70). Patients with stage III–IV, elevated β2 microglobulin (β2-MG), and B symptoms seemed to be more prone to progress within 24 months of frontline therapy (POD24). The FLIPI-2 showed the highest specificity to predict POD24, reflecting the prediction of correctly classifying as low-risk patients, but the FLIPI had the highest sensitivity to predict the risk of progression for critical patients.ConclusionsWe revealed the clinical characteristics and outcomes of FL patients in the real world in China, which may provide novel data on prognostic factors and primary treatment of FL, applicable to routine clinical practice.

Use of a new off-the-shelf 3D-printed trabecular titanium acetabular cup in Chinese patients undergoing hip revision surgery: Short- to mid-term clinical and radiological outcomes

BackgroundRevision total hip arthroplasty (THA) has been a challenge for surgeons. The purpose of this study was to explore the short-to mid-term clinical and radiological outcomes of Chinese patients who underwent revision THA using a new off-the-shelf three-dimensional (3D)-printed trabecular titanium (TT) acetabular cup by comparison with a conventional porous coated titanium acetabular cup, to provide a reference for the recommendation of this prostheses.MethodsA retrospective analysis of 57 patients (57 hips) who received revision THA was performed from January 2016 to June 2019. A total of 23 patients received 3D-printed cups (observation group) and 34 patients received non-3D-printed cups (control group). Clinical scores including Visual Analogue Scale (VAS), Harris Hip Score (HHS) and Short Form 36 (SF-36), upward movement of the hip center of rotation(HCOR)and limb-length discrepancy (LLD), stabilization and bone ingrowth of cups were compared between two groups. The multivariate linear regression was used to determine the factors potentially influencing the HHS score. Postoperative complications in the two groups were also recorded.ResultsAll 57 patients were routinely followed up. The average follow-up durations in the control and observation groups were 43.57 ± 13.68 (24–65) months and 41.82 ± 11.44 (24–64) months, respectively (p = 0.618). The postoperative clinical scores significantly improved in both groups compared to the preoperative scores (p < 0.001). The VAS score did not significantly differ between the groups at 3 (p = 0.946) or 12 (p = 0.681) months postoperatively, or at the last follow-up (p = 0.885). The HHS score did not significantly differ between the groups at 3 months (p = 0.378) postoperatively but differed at 12 months (p < 0.001) postoperatively and the last follow-up (p < 0.001). The SF-36 score did not significantly differ between the groups at 3 months (p = 0.289) postoperatively, but was significantly different at 12 months (p < 0.001) postoperatively and the last follow-up (p < 0.001). Compared with the control group, the postoperative recovery of HCOR and LLD was better in the observation group. All cups remained stable, with no loosening throughout the follow-up period. But the observation group had a significantly better rate of bone ingrowth compared to the control group (p = 0.037). Multivariate linear regression analysis showed that different cup types, upward movement of the HCOR, and LLD influenced the HHS score at the last follow-up (p < 0.001, p = 0.005, respectively). None of the patients exhibited severe postoperative complications.ConclusionThe new off-the-shelf 3D-printed TT acetabular cup demonstrated encouraging short-to mid-term clinical outcomes in Chinese patients. It can effectively relieve pain, improve hip function, provide satisfactory biological fixation and high survival rate. But further follow up is necessary to assess its long-term outcomes.

Impact of the PEAR1 polymorphism on clinical outcomes in Chinese patients receiving dual antiplatelet therapy after percutaneous coronary intervention.

Background: Patients might still experience major adverse cardiovascular events even with dual antiplatelet therapy after percutaneous coronary intervention. Our study aimed to explore the impact of gene polymorphism on clinical outcomes in one-year follow-up. Methods: A total of 171 patients treated with dual antiplatelet therapy afterpercutaneous coronary intervention from April to December 2020 in the first hospital of Jilin University enrolled in this study. Results: PEAR1 genetic polymorphisms was associated with the arachidonic acid(AA) and adenosine diphosphate(ADP) platelet aggregation. Hyperglycemia was associated with the rate of major adverse cardiovascular events. PEAR1GA+AA genetic genetic polymorphisms is associated with hyperglycemia. Conclusion:PEAR1 GG is a risk factor for AA and ADP platelet aggregation. Hyperglycemia can effect the one-year outcome. PEAR1 GA+AA genetic polymorphisms are associated with hyperglycemia.

Effect of Obesity on Left Ventricular Remodeling and Clinical Outcome in Chinese Patients With Hypertrophic Cardiomyopathy: Assessed by Cardiac MRI.

Obesity is highly prevalent in patients with hypertrophic cardiomyopathy (HCM) and believed to influence its phenotype. To explore the effects of obesity on left ventricular (LV) remodeling and long-term clinical course in Chinese patients with HCM. Longitudinal. A total of 247 patients with HCM classified according to body mass index (BMI) (normal weight: BMI=18.0-22.9kg/m2 [N=90]; overweight: BMI=23.0-24.9kg/m2 [N=58]; and obese: BMI ≥ 25 kg/m2 [N=99]). 3.0 T/Balanced steady-state free precession sequence and phase-sensitive inversion recovery late gadolinium enhancement (LGE) sequence. LV function and geometry were measured. LV peak strain analysis was performed. The presence and percentage of LGE in the LV were recorded. The endpoints including heart failure, sudden cardiac death, and overall composite outcome were assessed during a median follow-up of 4.1 years (interquartile range, 3.0-6.2 years). One-way analysis of variance, Kruskal-Wallis test, or chi-square test; Pearson correlation coefficient (r); multivariable linear regression analysis; Kaplan-Meier survival analysis; and Cox proportional hazards model analysis were conducted. A two-tailed P-value < 0.05 was considered statistically significant. Obese patients exhibited a significant progressive increase in LV mass compared with normal-weight patients. The magnitude of all LV strain indices gradually and significantly decreased as BMI increased, whereas LV ejection fraction was not significantly different among BMI groups (P=0.364). Multivariable linear regression analysis showed that obesity had a significant association with impaired strain indices as well as with indexed LV mass. Multivariable Cox model analysis retained obesity as an independent marker for future endpoints, and conveyed a > 3-fold increase in risk compared with patients with normal weight (hazard ratio, 3.04; 95% confidence interval, 1.07-6.57). Obesity is an important environmental modifier that is associated with adverse LV remodeling and is independently associated with future clinical outcomes in Chinese patients with HCM. 3 TECHNICAL EFFICACY: Stage 2.

Association of Mild Thyroid Dysfunction and Adverse Prognosis Among Chinese Patients With Acute ST Segment Elevation Myocardial Infarction.

AimsThyroid hormones widely affect the cardiovascular system, but the effects of mild thyroid dysfunction on the clinical prognosis of patients with acute ST segment elevation myocardial infarction (STEMI) remains unclear. Our aims were to analyze the relations between mild thyroid dysfunction at admission and clinical outcomes in Chinese patients with STEMI.MethodsA total of 1,176 STEMI patients with the available data of thyroid function and follow-up were analyzed, including 348 patients with mild thyroid dysfunction [subclinical hypothyroidism (n=81), hyperthyroidism (SHyper) (n=51), and low triiodothyronine syndrome (LT3S) (n=216)] and 828 patients with euthyroid function. During a median 4.4-year follow-up, in-hospital mortality, cardiac and all-cause mortalities were subsequently compared among the four groups.ResultsCompared with the euthyroid group, STEMI patients in the SHyper and LT3S groups faced obviously increased risks of in-hospital death [odds ratio (OR): 5.007, 95% confidence interval (CI): 1.246–20.124, p = 0.023 and OR: 2.491, 95% CI: 1.054–5.887, p = 0.037, respectively) even after adjustment for various confounding factors. During a median 4.4-year follow-up, STEMI patients with LT3S at baseline had higher cardiovascular mortality [hazard ratio (HR): 1.880, 95% CI: 1.178–2.998, p = 0.008] and all-cause mortality HR: 1.647, 95% CI: 1.072–2.531, p = 0.023] than those with euthyroid at baseline, whereas no significantly increased mortality was found for STEMI patients with SCH and SHyper at baseline.ConclusionsSTEMI patients with SHyper at admission had increased risk of in-hospital mortality, and STEMI patients with LT3S at baseline had worse prognosis and higher incidences of in-hospital mortality and cardiovascular and all-cause deaths compared with euthyroid patients.

Expert Consensus on Cognitive Dysfunction in Diabetes

The incidence of diabetes is gradually increasing in China, and diabetes and associated complications, such as cognitive dysfunction have gained much attention in recent time. However, the concepts, clinical treatment, and prevention of cognitive dysfunction in patients with diabetes remain unclear. The Chinese Society of Endocrinology investigated the current national and overseas situation of cognitive dysfunction associated with diabetes. Based on research both in China and other countries worldwide, the Expert Consensus on Cognitive Dysfunction in Diabetes was established to guide physicians in the comprehensive standardized management of cognitive dysfunction in diabetes and to improve clinical outcomes in Chinese patients. This consensus presents an overview, definition and classification, epidemiology and pathogenesis, risk factors, screening, diagnosis, differential diagnosis, treatment, and prevention of cognitive dysfunction in patients with diabetes.

Comparison of Different Dosages of Alteplase in Atrial Fibrillation-Related Acute Ischemic Stroke After Intravenous Thrombolysis: A Nationwide, Multicenter, Prospective Cohort Study in Taiwan.

BackgroundInsufficient evidence is available for patients with acute ischemic stroke with atrial fibrillation (AF) to determine the efficacy and safety of different dosages of intravenous thrombolysis treatment. This study examined clinical outcomes in Chinese patients with stroke with and without AF after intravenous thrombolysis treatment with different intravenous thrombolysis doses.Methods and ResultsThis multicenter, prospective cohort study recruited 2351 patients with acute ischemic stroke (1371 with AF and 980 without AF) treated with intravenous thrombolysis using alteplase. The Totaled Health Risks in Vascular Events score is a validated risk‐scoring tool used for assessing patients with acute ischemic stroke with and without AF. We evaluated favorable functional outcome at day 90 and symptomatic intracranial hemorrhage within 24 to 36 hours and outcomes of the patients receiving different doses of alteplase. Compared with the non‐AF group, the AF group exhibited a 2‐ to 3‐fold increased risk of symptomatic intracranial hemorrhage according to the National Institute of Neurological Disorders and Stroke standard (relative risk [RR], 2.10 [95% CI, 1.35–3.26]). Favorable functional outcome at 90 days and symptomatic intracranial hemorrhage rates according to the European Cooperative Acute Stroke Study II and the Safe Implementation of Thrombolysis in Stroke‐Monitoring Study standards did not significantly differ between the AF and non‐AF groups. In addition, the low‐dose alteplase subgroup exhibited an increased risk of symptomatic intracranial hemorrhage according to the National Institute of Neurological Disorders and Stroke standard (RR, 2.84 [95% CI, 1.63–4.96]). A validation study confirmed these findings after adjustment for scores determined using different stroke risk‐scoring tools.ConclusionsDifferent alteplase dosages did not affect functional status at 90 days in the AF and non‐AF groups. Thus, the adoption of low‐dose alteplase simply because of AF is not recommended.

Short-acting beta-2 agonist prescription patterns and clinical outcomes in Chinese patients with asthma: an observational study in mainland China for the SABINA programme.

Objectives:The SABINA CHINA study aimed to determine prescription data for asthma medication with a focus on SABA and ICS in a representative population of patients with asthma in China.Methods:SABINA China was a multicentre, observational, cross-sectional study with data collected retrospectively from a convenience sample of 25 tertiary centres across China. Patients (age ⩾ 12 years) with ⩾3 consultations/year were enrolled. Data were collected on clinical characteristics, asthma severity, and symptom control (as per GINA 2017), treatment and history of severe exacerbations over the past year. SABA over-prescription was defined as ⩾3 SABA canisters/year. Descriptive statistics are presented.Results:Between March and August 2020, 498 patients were included in the outcome analysis. Mean (SD) age was 48.7 (15.0) years, 57.9% were female and 91% had moderate-to-severe asthma (n = 453). Overall, 12.5% (n = 62) and 26.4% (n = 131) of patients had uncontrolled and partly controlled asthma, respectively. SABA add-on was prescribed to 20.3% (n = 101) of patients; one patient with moderate-to-severe asthma was prescribed SABA-alone. SABA over-prescription in the overall population was 4.0% (n = 20; all with moderate-to-severe asthma) and 19.8% (20/101) among those prescribed SABA add-on. In the mild asthma group, 50% (n = 22) were prescribed ICS/LABA and 43.2% (n = 19) were prescribed LTRA. Among those with moderate-to-severe asthma, 97.4% (n = 441) were prescribed ICS/LABA and 55.0% (n = 249) were prescribed LTRA. Approximately 30% of patients (n = 149) experienced ⩾1% and 6.6% (n = 33) ⩾3 severe exacerbations in the preceding year; mean annual number of severe exacerbation/patient was 0.6 (1.2). Among those prescribed SABA add-on, ICS/LABA and LTRA (non-mutually exclusive groups due to overlapping prescriptions), 54.5%, 29.9%, and 35.3% had ⩾1 severe exacerbations, respectively.Conclusion:Among patients with predominantly moderate-to-severe asthma managed in tertiary care and were prescribed SABA, 1 in 5 received ⩾3 canisters/year. Fewer patients who received ICS/LABA prescriptions experienced annual exacerbations than those prescribed SABA add-on.
