ABSTRACT
Objective:To investigate the correlation between triglyceride-glucose (TyG) index and high on-treatment platelet reactivity (HTPR) during clopidogrel treatment in patients with ischemic stroke.Methods:Patients with ischemic stroke who received maintenance dose of clopidogrel (75 mg/d) in the Department of Neurology, Guangdong Provincial Hospital of Chinese Medicine from January 2017 to March 2021 were retrospectively included. The highest quartile (Q4) of the TyG index was defined as insulin resistance. Platelet reactivity was assessed by thromboelastogram and clopidogrel HTPR was defined as the clot strength induced by adenosine diphosphate (MA ADP) >47 mm. Multivariate regression model was used to analyze the independent correlation between TyG index and platelet reactivity. Results:A total of 83 patients were included. The TyG index showed a linear correlation with MA ADP. The patients were divided into 4 groups according to the quartile of TyG index. The incidence of clopidogrel HTPR increased significantly with the increase of the quartile of the TyG index ( Ptrend=0.017). Multivariate analysis showed that there was a significant independent correlation between insulin resistance and clopidogrel HTPR (odds ratio 4.597, 95% confidence interval 1.285-16.446; P=0.019). Conclusions:In patients with ischemic stroke treated with clopidogrel, the incidence of clopidogrel HTPR gradually increases with the increase of the quartile of the TyG index. The insulin resistance assessed by the TyG index is independently associated with clopidogrel HTPR.
ABSTRACT
Essential palatal tremor is relatively rare in clinical practice, which manifests involuntary and rhythmic contraction of soft-palate along with auditory click. The cause is unknown and there is no specific treatment at present. This article reports a female patient with essential palatine tremor, who presented with involuntarily beating of soft palate, disappeared during sleep, had sensory tricks, and gradually developed mental and psychological problems such as anxiety disorders. After treatment with integrated traditional Chinese and Western medicine, the symptoms improved. The clinical features of the case were analyzed, relevant literature was reviewed, and the possible etiology and characteristics of the disease were explored, so as to provide reference for clinical diagnosis and treatment.
ABSTRACT
Objective To explore the outcome of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for relapsed/refractory acute myeloid leukemia (AML) patients in nonremission (NR) status and its related risk factors.Methods Thirty-nine relapsed/refractory AML patients in NR status who received allo-HSCT between Jan.2006 and Dec.2016 were retrospectively analyzed.Major end points of study included overall survival (OS),disease free survival (DFS),and relapse rate.Results All patients achieved hematopoietic reconstitution.Median time to neutrophil and platelet engraftment was 13 (11 20) and 16 (10-58) days,respectively.Acute graft-versus-host disease (aGVHD) occurred in 25 (64.1％) patients,and 11 (31.4％) patients developed chronic GVHD.During a median follow-up period of 9.1 (1.6-93.8) months,11 (28.9％) cases survived,10(26.3％) survived without leukemia,and 21 (53.8％) relapsed.The estimated 2 year OS and DFS were 30.0％ ± 8.0％ and 26.7％ ± 7.7％,and cumulative incidence of relapse and transplantation related mortality at 2 years was 56.63％ (95％ CI 37.84％-71.71％),19.7％ (95％ CI 8.3％-34.5％),respectively.The multivariate analysis revealed that the number of bone marrow blasts≥25％ or any level of blasts in peripheral blood was significantly associated with worse OS (HR =11.91,P=0.003),DFS (HR =10.75,P =0.002) and higher rate of relapse (70.83％ versus 20.22％,P =0.002).In addition,the development of grade Ⅱ-Ⅳ aGVHD also predicted an inferior OS (HR =3.18,P =0.039).Conclusion Salvage therapy with allo-HSCT can induce long-term survival in part refractory/relapsed AML patients.Decrease in the pre-transplant disease burden is the key to reduce relapse and improve survival.
