ABSTRACT
OBJECTIVE To reevaluate systematic reviews/meta-analysis of efficacy and safety of tolvaptan for hyponatremia. METHODS Retrieved from CNKI， Wanfang Data， VIP， CBM， PubMed， Embase and the Cochrane Library database， systematic reviews/meta-analysis about tolvaptan for the treatment of hyponatremia were included from the inception to June 15， 2022. After screening literature and extracting data， the PRISMA statement， AMSTAR 2 scale and GRADE method were used to evaluate the reporting quality， methodological quality and evidence quality of the included literature， respectively. RESULTS A total of 6 articles were included， of which 1 was systematic review and 5 were meta-analysis， including 56 outcome indicators. All of the 6 studies had PRISMA scores ranging from 15.0 to 20.5， and the quality of them was moderate. Results of the AMSTAR 2 scale showed that the methodological quality of 5 literatures were very low， and the quality of 1 literature was low. The quality of GRADE evidence showed that there were 6 moderate-quality indicators， 13 low-quality indicators， 35 very low-quality indicators， and 2 indicators that could not be assessed due to missing data. The main factors causing degradation were limitations， inconsistency， imprecision and publication bias. In terms of efficacy， tolvaptan could effectively increase the level of serum sodium， increase urine volume， reduce body weight， reduce abdominal circumference， relieve edema， and reduce alaninetransaminase level. In terms of safety， the incidence of total adverse drug reaction induced by tolvaptan was controversial； it may increase the risk of dry mouth， thirst， frequent urination or excessive correction of serum sodium. CONCLUSIONS Tolvaptan has great efficacy in the treatment of hyponatremia， but serum sodium overcorrection should be avoided in terms of safety. Relevant systematic reviews/meta-analysis have shortcomings of low reporting quality， methodological quality and evidence quality， which may reduce the reliability of the results， so the results should be treated with caution.
ABSTRACT
OBJECTIVE@#To investigate the classification of idiopathic inflammatory myopathies (IIM) based on clinical manifestations and myositis- specific antibodies using cluster analysis.@*METHODS@#We retrospectively analyzed the data of patients with IIM admitted in Nanfang Hospital in 2015-2019. The clinical data of the patients including serum creatine kinase (CK), interstitial lung disease (ILD), cancer, and myositis-specific antibodies were collected for two-step cluster analysis to identify the distinct clusters of patients, whose clinical characteristics were subsequently analysed.@*RESULTS@#A total of 71 patients with IIM were included in this study, including 30 (42.3%) with polymyositis (PM), 20 (28.2%) with classic dermatomyositis (DM), 16 (22.5%) with amyopathic dermatomyositis (CADM), and 5 (7.0%) with immune-mediated necrotizing myopathy (IMNM). Two-step cluster analysis identified 3 distinctive subgroups: Cluster 1 of 15 (51.7%) patients characterized by rash, positive anti-MDA5 antibody and hypoproteinemia ( < 0.05) with normal or slightly elevated CK level, mainly corresponding to CADM; Cluster 2 of 4 (57.1%) patients with significantly elevated CK and positive anti-SRP antibody ( < 0.001) corresponding to IMNM; and Cluster 3 of 17 (48.6%) patients consisting primarily of patients with PM, characterized by positivity for anti- aminoacyl transfer RNA synthetases antibodies (=0.022) corresponding to antisynthetase syndrome (ASS).@*CONCLUSIONS@#Patients with IIM can be divided into 3 subgroups based on their clinical and serological characteristics (especially myositis-specific antibodies), and among them ASS may represent an independent IIM subgroup with unique clinical characteristics.

Objective Based on the medical records and follow-up records of hospitalized patients who received anti-tuberculosis therapy in the Third People' s Hospital of Zhenjiang in Jiangsu province from 2006 to 2012,we investigated the incidence and outcome of anti-tuberculosis drug induced hepatotoxicity (ATDH) and provided evidence for the prevention of ATDH.Methods According to tuberculosis patients' medical information and liver function test records,ATDH patients were diagnosed according to the criteria of International Consensus Meeting and American Thoracic Society respectively,then the related factors and outcomes were analyzed.Results A total of 1 967 hospitalized tuberculosis patients were reviewed retrospectively,in which 1 403 (71.3％) were men,1 790 (91.0％) were pulmonary tuberculosis patients,1 528 (77.8％) were patients receiving initiative treatment,979 (49.8％) were sputum smear-positive patients,and 1 297 (65.9％) had other complicated diseases.According to the criterion of International Consensus Meeting,the incidence of ATDH was 16.5％,the median time of onset was 25 days.According to the criterion of American Thoracic Society,the incidence of ATDH was 8.3％,the median time of onset was 23 days.The incidence of ATDH was significantly higher in males and HRZE therapy group (P＜0.05).Under the two liver criteria,69.5％ and 70.1％ of the patients changed primary therapy respectively after ATDH occurred.89.8％ and 88.4％ patients' liver function returned to normal range after changing or stopping therapy.Conclusion According to two liver injury criteria,the incidences of ATDH were 16.5％ and 8.3％ in hospitalized tuberculosis patients respectively,and ATDH mainly occurred in the furst month of anti-tuberculosis treatment.The monitoring of liver function should be strengthened in males and HRZE therapy group to reduce the incidence of ATDH.
