RESUMO
Objective:To explore the clinical significance of hepatitis B virus (HBV) DNA detection in screening patients with hepatitis B.Methods:Clinical data of 682 331 hepatitis B patients were retrospectively analyzed. The HBV DNA of these patients was detected in the Fifth Medical Center of the PLA General Hospital from January 2017 to December 2021, there were 481 159 males and 201 172 females in this cohort, the average age was (41.34±16.13) years. Patients were divided into HBV DNA positive group (219 879 cases) and HBV DNA negative group (462 452 cases). Clinical characteristics, data of five serologic markers of hepatitis B and hepatitis B surface antigen quantification (HBsAg-QN), liver function, alpha fetoprotein (AFP) and prothrombin time (PT) results were collected and analyzed and compared between the two groups.Results:The positive rate of HBV DNA was 32.22% (219 879/682 331) in this cohort. Among the different age groups, the positive rate of HBV DNA was the highest (40.34%, 128 038/317 380) in young people aged 18-44 years. The proportion of patients was lower among aged <1, 45-59 and ≥60 years patients in HBV DNA positive group than that in HBV DNA negative group, while the proportion of patients was higher among aged 1-17 and 18-44 years patients in HBV DNA positive group than that in HBV DNA negative group (all P<0.001). Among 2 291 <1-year-old infants tested for HBV DNA, 71 infants were HBV DNA positive. The positive rates of HBV DNA from 2017 to 2021 were 4.86% (27/556), 3.68% (14/380), 3.47% (17/490), 1.55% (6/386) and 1.46% (7/479) respectively, showing a downward trend year by year. The positive rate of HBV DNA in acute hepatitis B (AHB) patients was the highest (49.88%, 208/417) among 680 040 patients with hepatitis B. The proportion of AHB patients (0.09%, 208/219 808) and chronic hepatitis B (80.44%, 176 806/219 808) in HBV DNA positive group was higher than that in HBV DNA negative group [0.05% (209/460 232) and 65.45% (301, 216/460 232)], while the proportion of patients with HBV-related liver cirrhosis (11.28%, 24 793/219 808), HBV-related liver cancer (6.72%, 14 775/219 808), liver cancer surgery (1.39%, 3 055/219 808) and liver transplantation (0.08%, 171/219 808) were lower than that in HBV DNA negative group [22.99% (105 813/460 232), 7.25% (33 385/460 232), 3.50% (16 129/460 232) and 0.76% (3 480/460 232)] (all P<0.001). At the same time, positive rate of hepatitis B surface antigen (HbsAg), HBsAg-QN, hepatitis B e antigen (HbeAg), level of total bilirubin, total bilirubin, AFP and PT were higher in HBV DNA positive group than those in HBV DNA negative group, while the age, male ratio and albumin results in HBV DNA positive group were lower than those in HBV DNA negative group (all P<0.01). The HBV DNA loads were higher in HBsAg positive group, hepatitis B surface antibody positive group and HBeAg positive group than those in respective negative groups, while the HBV DNA loads were lower in hepatitis B e antibody positive group and hepatitis B core antibody positive group than those in respective negative groups (all P<0.001). Conclusions:The mother to child transmission rate of<1-year-old infants decreases year by year. HBV DNA is an important factor for the progression of hepatitis B disease. HBV DNA positive hepatitis B patients with higher HBsAg-QN values are more likely to have abnormal serum markers such as liver dysfunction. HBV DNA detection is therefore of clinical importance in screening patients with hepatitis B.
RESUMO
【Objective】 To investigate the preoperative anemia and perioperative blood transfusion in patients with duodenal papillary carcinoma who underwent Whipple surgery. 【Methods】 The clinical data of 1 959 cases with duodenal papillary carcinoma, subjected to Whipple surgery, were retrospectively analyzed. 【Results】 The rate of anemia in preoperative patients with duodenal papillary carcinoma was 54.87%(1 075/1 959). The incidence rate of anemia in the three age groups from low to high was 44.92% (≤50 years old, 190/423), 52.82% (51~64 years old, 506/958), and 65.57% (≥65 years old, 379/578) (P<0.05), and the highest rate of anemia occurred in patients aged above 65. There was a significant statistical difference among patients with different body mass index (BMI)(P<0.05). Patients with moderate or severe anemia received more red blood cells than patients with mild anemia during the perioperative period (P<0.05). The average hospitalization time of the blood transfusion patients was 27.25 days, and that of non-transfusion patients was 22.22 days (P<0.05). The amount of blood loss and hospitalization time of patients underwent laparoscopic and robotic surgery were significantly lower than those underwent open surgery patients (P <0.05). There were only 24.09%(186/772) treated with drugs for anemia intervention and the majority of patients (75.91%, 586/772) were treated with blood transfusions to interfere with anemia during hospitalization. 【Conclusion】 There are significant differences in the incidence rate of preoperative anemia among patients with duodenal papillary carcinoma who undergone Whipple surgery. Low BMI, abnormal WBC, and perioperative blood transfusion are high-risk factors for prolonged hospital stay, whereas anemia is not associated with prolonged hospital stay.
