RESUMO
Objective:To investigate the pathogens and drug resistance of bacterial enteritis in children, analyze the clinical characteristics of bacterial enteritis in children, and provide basis for clinical diagnosis and treatment.Methods:The fecal culture strain and drug sensitivity of patients with bacterial enteritis admitted to our hospital from January 2016 to December 2020 were analyzed and summarized, and the clinical characteristics of patients who were infected by Salmonella and Escherichia coli were compared.Results:There were a total of 173 patients, aged from 21 days to 15 years, with a median age of 2.00(1.10, 3.54)years.Bacterial enteritis was most likely to occur in summer and autumn, and the incidence rate was 40.5% and 29.5%, respectively.One hundreds and seventy-three strains of bacteria were cultured in feces, including 148 strains of Salmonella(85.5%), 18 strains of Escherichia coli(10.4%), five strains of Staphylococcus aureus and two strains of Shigella.One hundreds and one of 141 patients who were infected with Salmonella were detected for leukocytes of in feces(71.6%), and four of 16 patients with Escherichia coli were detected for leukocytes(25.0%). The difference was significant( χ2=14.1, P<0.001). Eighty-eight of 113 patients(77.9%) who were infected by Salmonella with increased CRP(CRP>8 mg/L)and the proportion in Escherichia coli infection cases was 6/13(46.2%). There was significant difference( χ2=4.63, P=0.03). The drug sensitivity of Salmonella and Escherichia coli was summarized.There was no carbapenem resistant strain cultured; The sensitivity to piperacillin/tazobactam and cefoperazone/sulbactam was higher than 85%; The sensitivity to cefepime, ceftazidimeand ceftriaxone was higher than 75%; The sensitivity to ampicillin was lower than 30%, and the sensitivity to quinolones was between 20%-40%. Conclusion:Children aged 1-3 years are prone to bacterial enteritis in summer and autumn.The most common pathogens causing bacterial enteritis are Salmonella and Escherichia coli.White blood cells are more easily detected in feces of patients with Salmonella infection, and the increase rate of C-reactive protein in peripheral blood is higher.Patients with bacterial enteritis are recommended to use the third-generation cephalosporins and aforementioned antibiotics and piperacillin/tazobactam for empirical treatment.The sensitivity to quinolones is reduced, and may not be suitable for clinical application.
RESUMO
Objective To investigate the clinical effect of cefixime on the treatment for patients with acute bacterial enteritis and the influence on serum inflammatory factors .Methods A total of 92 cases with acute bacterial enteritis ,treated in our hospital from June 2015 to September 2016 ,were selected as the research object ,and randomly divided into cefixime group and cefaclor group , with 46 cases in each group .The cefixime group was given treatment of cefixime ,and cefaclor group was given treatment of cefa-clor ,for 5 to 7 consecutive days .Observation of clinical treatment effect was performed .Results On the first three days after treat-ment ,the number of diarrhea of cefixime group is lower than the one of cefaclor group ,and the difference was statistically significant (P<0 .05);after Day 3 of treatment ,the levels of CRP ,CER ,AAG ,IL-8 ,PCT ,TNF-alpha of cefixime group were lower than those of cefaclor group ,and the difference was statistically significant (P<0 .05);after Day 3 of treatment ,efficiency rate ,effective rate and invalid rate of cefixime group were 50 .0% ,47 .83% and 2 .17% ,respectively ;efficiency rate ,effective rate and invalid rate of cefaclor group were 32 .61% ,56 .52% and 10 .87% respectively ;the treatment effect of cefixime group is better than that of cefaclor group ,and the difference was statistically significant (P<0 .05) .Conclusion The clinical effects of cefixime on the treatment for patients with acute bacterial enteritis is better than that of cefaclor .
RESUMO
Objective To analysis effect of Bifidobacterium tetravaccine tablets ( live ) combined with cefixime on C-reactive protein, ceruloplasmin, haptoglobin and α1-acid glycoprotein in patients with Bacterial enteritis.Methods 58 patients who were diagnosed with Bacterial enteritis were collected.All patients were randomly divided into experimental group and control group, 29 cases in each group, On the basis of conventional treatment, the control group was treated with cefixime, and the experimental group was treated with Bifidobacterium tetravaccine tablets ( live) on the basis of control group.After treatment, the serum levels of CRP, CER, HPT, AAG and clinical curative effect were detected in all patients.Results After treatment, CRP, CER, HPT, AAG levels were lower than before treatment (P<0.05),compared with control group, CRP, CER, HPT, AAG levels were lower than in the experimental group( P<0.05);the total effective rate was higher in the experimental group (χ2 =4.35, P<0.05).Conclusion Bifidobacterium tetravaccine tablets(live) combined with cefixime can significantly reduce the serum CRP, CER, HPT, AAG levels in patients with bacteria enteritis, improve the clinical efficacy, have guidance significance for clinic.
