ABSTRACT
Objective:To investigate the antiviral efficacy of direct-acting antiviral agents (DAAs) in the treatment of liver transplantation (LT) recipients with hepatitis C virus (HCV) infection.Methods:Twenty-two HCV-infected LT recipients treated with DAAs at Fifth Medical Center of Chinese PLA General Hospital from December 2014 to June 2018 were retrospectively analyzed, Twenty cases of HCV RNA gene type 1b were treated with sofosbuvir (400 mg/d) + ledipasvir (90 mg/d) or sofosbuvir (400 mg/d) + daclatasvir (60 mg/d) for 12 weeks or 24 weeks; 2 cases of gene type 2a were treated with sofosbuvir (400 mg/d) for 12 weeks. The effect of antiviral treatment, adverse reactions during treatment, and laboratory indicators such as HCVRNA quantification, blood routine, liver and kidney function during treatment and follow-up were studied.Results:The LT recipients of HCV infection included 16 males and 6 females, with a median age of 61.5 (36-71) years old, and the median time of antiviral treatment was 48 (2-117) months after transplantation. Among the 22 patients, 16 received a 12-week course of treatment. Except for 2 patients who did not get HCVRNA negative conversion at 4-week, all achieved a negative HCV RNA at 4-week and the end of the treatment. Six LT recipients received a 24-week course of treatment (gene type 1b), and HCVRNA was negative at 4-week and the end of treatment. All patients achieved end of treatment virological response and a sustained virological response (SVR) rate of 100% at 12 weeks and 24 weeks after the end of treatment. The serum levels of alanine aminotransferase (ALT) and creatinine were 71.5 (30, 110) U/L and (89.4±25.7) mmol/L before treatment, respectively. ALT decreased to 22 (17.8, 28.5) U/L after 4 weeks of treatment, and serum creatinine decreased to (77.4±11.5) mmol/L at 24 weeks after the end of treatment. The differences before and after treatment were statistically significant (all P<0.05). No serious adverse events occurred during the treatment. Conclusions:DAAs have a definite antiviral effect in the treatment of LT recipients with HCV infection, and long-term SVR can be obtained.
ABSTRACT
Objective:To investigate and analyze the epidemiological and clinical characteristics of 46 patients with corona virus disease 2019 (COVID-19) in Beijing City.Methods:A retrospective study was conducted to analyze the data of 46 patients with COVID-19 in Beijing from 20th January 2020 to 8th February 2020 at the Fifth Medical Center of the PLA General Hospital in Beijing City. Twelve, 23 and 11 patients were assigned to the mild group, common group and severe group, respectively. The epidemiological history, clinical characteristics, laboratory tests and imaging inspections were analyzed. Statistical analysis used Fisher exact test. If P<0.05, post- hoc test was used for pairwise comparison, and the statistics were corrected by Bonferroni test. Results:Among the 46 patients included in this study, 27 were male and 19 were female. The age range was between 3-79 years old, and the age was (41.8±16.3) years old. The average incubation period was (4.85±3.00) days. A total of 26 cases (56.5%) were clustered patients, and 26 cases had a history of staying in Wuhan, 10 cases had contact with Wuhan personnel. Fever (39 cases, 84.8%), cough (27 cases, 58.7%), and fatigue (25 cases, 54.3%) were the main clinical symptoms for these patients. The decrease in white blood cell counts occurred in 12 patients, four had the decrease in T lymphocyte percentage, 17 had the decrease in CD4 + T lymphocyte counts, seven had the decrease in CD8 + T lymphocyte counts, 21 had the increase level of C reactive protein (45.7%), and interleukin-6 (IL-6) level increased in 32 cases (69.6%), erythrocyte sedimentation rate (ESR) increased in 23 cases (50.0%), serum ferritin level increased in 26 cases (56.5%), and blood lactic acid level increased in nine cases. There were statistically significant differences in the proportion of cases with decreased absolute value of CD8 + T lymphocytes and T lymphocytes counts among the mild, common and severe groups (all P<0.05). Comparing the proportion of cases in the three groups with elevated C reactive protein, IL-6, ESR, serum ferritin and blood lactic acid levels, the differences were statistically significant (all P<0.05). The proportion of cases with elevated C reactive protein levels in severe group was higher than those in mild and common groups. The proportion of cases with elevated IL-6, ESR, and serum ferritin levels in severe and common group were higher than those in mild group. The proportion of cases with elevated blood lactic acid levels in severe group was higher than those in mild group. The differences between the above groups were statistically significant (all adjusted P<0.017). Analysis of chest X-rays results showed that 34 patients (73.9%) had inflammation in the lungs. Conclusions:The epidemiological characteristics of patients with COVID-19 in Beijing City are mainly imported cases and clustered cases. The clinical manifestations are mainly fever, fatigue and cough. C reactive protein, IL-6, ESR, serum ferritin and blood lactic acid levels are higher in severe patients.
ABSTRACT
BACKGROUND:Prolonged therapy with lamivudine has been associated with tyrosine-methionine-aspartate-aspartate mutation, which results in hepatitis B recurrence. Recently, antiviral agents, such as entecavir, have high efficacy and low resistance rate in hepatitis B-related liver disease. However, the researches on the effect of entecavir in preventing hepatitis B recurrence after liver transplantation are rare. OBJECTIVE:To investigate the effect of entecavir combined with low-dose hepatitis B immunoglobulin in preventing hepatitis B recurrence after liver transplantation. METHODS:The fol ow-up data of 253 patients who had liver transplantation for hepatitis B virus related liver disease were retrospectively analyzed. Al patients received nucleoside analogues therapy formal y before liver transplantation. The effects of entecavir+hepatitis B immunoglobulin and lamivudine+hepatitis B immunoglobulin were compared in al the patients and the patents with hepatitis B recurrence risk factors (positive preoperative HBeAg, DNA-positive hepatitis B virus, hepatoma and tyrosine-methionine-aspartate-aspartate mutation). RESULTS AND CONCLUSION:A total of 253 patients received hepatitis B virus-related liver transplantation, and 29 patients died. There were 202 patients in lamivudine group in which 26 patients were dead and 16 patients had hepatitis B virus recurrence, and the recurrence rate was 7.92%(16/202). However, entecavir group had 51 patients without hepatitis B virus recurrence in which three patients were dead. There were significant differences in the mortality rate and recurrence rate between two groups. Compared with the lamivudine+hepatitis B immunoglobulin, entecavir+hepatitis B immunoglobulin could effectively reduce the recurrence rate of the patients with hepatitis B virus-related risk factors. Hepatitis B immunoglobulin was terminated and nucleoside analogues were modulated when recurrence appeared. Al patients hepatitis B virus DNA were control ed less than 500 IU/mL and liver function returned to normal level. Log-rank test showed that there was no significant difference in the long-term survival rate after timely treatment of hepatitis B virus recurrence. With the prevention of nucleoside analogues combined with hepatitis B immunoglobulin therapy, timely treatment of hepatitis B recurrence has little influence on the prognosis. Entecavir combined with hepatitis B immunoglobulin can effectively prevent the hepatitis B recurrence. For the patients with hepatitis B virus-related risk factors, entecavir combined with hepatitis B immunoglobulin can better reduce the recurrence rate of hepatitis B than lamivudine+hepatitis B immunoglobulin after liver transplantation.
