RESUMO
Objective:To investigate Helicobactor pylori (H. pylori) infection status and interfamilial transmission pattern in Zhengzhou area. Methods:A cross-sectional study was conducted from September 2020 to march 2021, among 731 individual from 266 families randomly selected from 9 communities of Zhengzhou area. H. pylori infection status was determined by serum antibody tests, and 13C-urea breath test was performed in the previously eradicated population to clarify the current infection status. The individual and familial infection rate, infection status for couples and children and adolescent were analyzed. Results:Among 731 individuals from 266 families, 397 of them were H. pylori positive. The individual infection rate was 54.31% (397/731); among infected individuals 77.83% (307/397) were infected with type Ⅰ strain, 22.67% (90/397) were infected by type Ⅱ strain. Annual household income ( χ2=0.419, 0.410, 0.213, all P>0.05), smoking history (χ 2=0.071, P>0.05), drinking history ( χ2=0.071, P>0.05), dining place ( χ2=0.009, P>0.05), gastrointestinal symptoms ( χ2=0.047, P>0.05), family history of gastric disease ( χ2=0.069, P>0.05), and history of gastric cancer ( χ2=0.004, P>0.05) had no significant differences between H. pylori-positive and -negative groups, but the infection rate in individuals with higher education level was lower ( χ2=4.449, P<0.05). The infection rate was significantly higher in≥18 age groups compared with<18 age groups ( χ2=6.531, 23.362, 20.671, 24.244, 37.948, 14.597 and 5.170, all P<0.05). The familial H. pylori infection rate was 87.59% (233/266), and in 61 families all member were infected (26.18%, 61/233). The positive rate was 23.08% (6/26) in 50 families with children under 18 years when both parents were infected. Among 231 coupled families, both couples were infected in 78 families (33.76%), one couple was infected in 113 families (48.92%), and both couples were not infected in 40 (17.32%). With the increase of marriage time, the infection rate of both spouses increased significantly ( χ2=7.775, 12.662, 15.487, all P<0.05). Conclusions:The distribution of H. pylori infection presents a family cluster pattern, and intrafamilial infection is an important transmission rout of H. pylori. The type I strain of H. pylori is the dominate strain in this area.
RESUMO
Objective To evaluate the prognosis of the decompensated liver cirrhosis by means of MELD-Na score combined with serum cholesterol and endotoxin concentration.MethodsData of 156 hospitalized patients with decompensated liver cirrhosis was retrospectively analyzed.Patients were divided into survival and death group according to follow-ups at 6 months,12 months and 24 months.MELD-Na score was made among 156 patients by detecting relevant indicators.Serum cholesterol and cholesterol levels were measured,too.The relationship between decompensated liver cirrhosis prognosis and MELD-Na score combined with serum cholesterol and endotoxin concentration was analyzed.ResultsNinteen patients died at the follow-up for 6 months.Fifty nine patients died at the followe-up for 12 months.Seventy seven patients died at the follow-up for 24 months.There was significant difference on MELD-Na score,endotoxin concentration and serum cholesterol between the survival group and the death group (t =-9.68,-9.22,11.4,-4.65,-19.60,16.20,-20.0,-18.7,17.3,respectively,P ＜0.05).The best critical value of MELD-Na score to predicate death in patients with decompensated liver cirrhosis was 32 points.The risk of death would rise if MELD-Na score increased.The best critical value of plasma endotoxin to predicate death in patients with decompensated liver cirrhosis was ≥ 12 ng/L.The best threshold value of serum cholesterol to predict death in patients with decompensated liver cirrhosis was ≤ 1.70 mmol/L.ConclusionMELD-Na score,serum cholesterol and serum endotoxin were of higher prognostic value to judge the prognosis of patients with decompensated liver cirrhosis.
