RESUMO
Objective@#To analyze the clinical characteristics of cases of novel coronavirus pneumonia and a preliminary study to explore the relationship between different clinical classification and liver damage.@*Methods@#Consecutively confirmed novel coronavirus infection cases admitted to seven designated hospitals during January 23, 2020 to February 8, 2020 were included. Clinical classification (mild, moderate, severe, and critical) was carried out according to the diagnosis and treatment program of novel coronavirus pneumonia (Trial Fifth Edition) issued by the National Health Commission. The research data were analyzed using SPSS19.0 statistical software. Quantitative data were expressed as median (interquartile range), and qualitative data were expressed as frequency and rate.@*Results@#32 confirmed cases that met the inclusion criteria were included. 28 cases were of mild or moderate type (87.50%), and four cases (12.50%) of severe or critical type. Four cases (12.5%) were combined with one underlying disease (bronchial asthma, coronary heart disease, malignant tumor, chronic kidney disease), and one case (3.13%) was simultaneously combined with high blood pressure and malignant tumor. The results of laboratory examination showed that the alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (ALB), and total bilirubin (TBil) for entire cohort were 26.98 (16.88 ~ 46.09) U/L and 24.75 (18.71 ~ 31.79) U/L, 39.00 (36.20 ~ 44.20) g/L and 16.40 (11.34- ~ 21.15) mmol/L, respectively. ALT, AST, ALB and TBil of the mild or moderate subgroups were 22.75 (16.31- ~ 37.25) U/L, 23.63 (18.71 ~ 26.50) U/L, 39.70 (36.50 ~ 46.10) g/L, and 15.95 (11.34 ~ 20.83) mmol/L, respectively. ALT, AST, ALB and TBil of the severe or critical subgroups were 60.25 (40.88 ~ 68.90) U/L, 37.00 (20.88 ~ 64.45) U/L, 35.75 (28.68 ~ 42.00) g/L, and 20.50 (11.28 ~ 25.00) mmol/L, respectively.@*Conclusion@#The results of this multicenter retrospective study suggests that novel coronavirus pneumonia combined with liver damage is more likely to be caused by adverse drug reactions and systemic inflammation in severe patients receiving medical treatment. Therefore, liver function monitoring and evaluation should be strengthened during the treatment of such patients.
RESUMO
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.

RESUMO
Objective To validate the association between genetic polymorphisms of nucleotide binding oligomerization domain 2 (NOD2) gene and the risk of tuberculosis in Chinese population.Methods A validation case-control study was performed with a total of 1043 pulmonary tuberculosis patients and 808 healthy controls.All controls had no history of tuberculosis or malignancy,and were matched with cases by sex and age.Genomic DNA from the peripheral blood samples of participant was extracted.Single nucleoside polymorphisms (SNP) of rs3135499,rs7194886,rs8057341,and rs9302752 in the NOD2 gene were genotyped using a TaqMan-based allelic discrimination system.The chi-square test was used to analyze categorical data and Logistic regression model was used to calculate the odds ratio (OR) and 95％ confidence interval (CI).Results When all patients as the cases were included in the analysis,no significant association was found between the four SNP of NOD2 gene and the risk of pulmonary tuberculosis.In a subgroup analysis by restricting cases to sputum culture positive patients,the variant genotypes of rs7194886 were significantly associated with an altered risk of tuberculosis.Compared with the CC genotype,individuals carrying the CT/TT genotype of rs7194886 had an increased risk (OR =1.35,95％ CI:1.05-1.72) for sputum culture positive tuberculosis.After adjusted for potential confounders,the increased risk of CT/TT genotype was still observed (OR=1.35,95％CI:1.05-1.73).Stratification analysis revealed that the effect of the SNP rs7194886 (CT/TT vs TT) was significant among men (OR=1.44,95％CI:1.08-1.92),individuals with age ＜55 years (OR=1.51,95％CI:1.05-2.16),smokers (OR=1.53,95％CI:1.07-2.18),and alcohol drinkers (OR=1.84,95％CI:1.01-3.33).But the heterogeneity test was not significant.Haplotype analysis showed that the rs9302752C-rs7194886T haplotype was associated with an increased risk of sputum culture positive tuberculosis (x2 =4.27,P=0.039).Conclusion In summary,genetic polymorphisms of rs7194886 in the NOD2 gene may be associated with the risk of pulmonary tuberculosis in the Chinese population.
