Objective To explore the pathogen distribution and the characteristics of antibiotics use of patients with positive bile culture in order to provide evidence for appropriate antibiotic use. Methods Using a patient-based approach, the clinical and laboratory data of patients with positive bile culture between December 1st 2016 and November 30th 2017 were retrospectively analyzed. The pathogen distribution and antibiotics use of patients with bililary duct infections and colonizations were analyzed. Multidrug-resistant organism infections of patients with bililary duct infections were studied. Results There were 299 submitted bililary samples and in which 158 were culture-positive (52.8%). One hundred and ten strains of pathogens were found in 79 patients with positive bile culture, including 66 strains of Gram-negative (G–) organisms (60.0%), 37 strains of Gram-positive (G+) organisms (33.6%), and 7 strains of fungi (6.4%). The top three G– organisms were Escherichia coli (25 strains, 22.7%), Klebsiella pneumoniae (9 strains, 8.2%), and Acinetobacter baumanii (7 strains, 6.4%). The top three G+ organisms were Enterococcus faecium (10 strains, 9.1%), Enterococcus faecalis (6 strains, 5.5%), and coagulase negativeStaphylococcus (6 strains, 5.5%). The number of patients with bililary duct infections and colonizations were 42 and 37, respectively, with pathogens occupied mainly by G– bacteria. Ten strains of multidrug-resistant organisms were isolated from patients with bililary duct infections. Compared to patients with non-multidrug-resistant organism infections, the length of antibiotics use was longer in patients with multidrug- resistant organism infections (t=2.129, P=0.039). The rate of target therapy for antibiotics in patients with bililary duct infections was 76.2%. The rate of proper antibiotics use was 16.2% before positive bile culture and 78.4% after positive bile culture in patients with bililary duct colonizations. Conclusions Pathogens isolated from bile culture of infection and colonization are predominantly G– organisms. The bile culture and blood culture should be done for patients with suspected bililary duct infection. Infection and colonization should be distinguished for positive bile culture and antibiotic should be chosen according to drug susceptibility test results.

Methods A total of 16 reported cases of antimicrobial agents-induced TDP were analyzed. Results The 16 cases including 3 males and 13 females at the age of 17-88 years with the mean age of 54. Six patients suffered from heart disease. The antimicrobial agents included moxifloxacin, sparfloxacin, cefradine, cefoperazone, fosfomycin, clindamycin, amphoterincin B, fluconazole, and itraconazole; which were used frequently, as well as some less frequently-used ones liked erythromycin, ketoconazole. The mean time from medication to onset of TDP was (5.1±6.6) days. Patients usually presented with palpitations at first following by prolonged QTc intervals, and then TDP appeared. Conclusion Clinical physicians and pharmacists should pay attention to antimicrobial agents-induced TDP.
ObjectiveTo investigate the clinical settings, antibiotic susceptibilities, management and outcomes of streptococcal endophthalmitis. MethodsA retrospective observational case series study. Fifty six eyes of 56 patients diagnosed with streptococcal endophthalmitis in Eye & ENT Hospital, Fudan University from 2012 to 2022 were collected. The treatment followed the general principles of relevant guidelines, including pars plana vitrectomy (PPV), vitreous injection of antibiotics (IVI), vitreous injection of glucocorticoids and systemic application of antibiotics. The follow-up time was (11.9±17.0) months. Patients' clinical characteristics, pathogenic distribution and antibiotic susceptibilities, treatment and outcomes in their medical records were retrospectively collected and analyzed. ResultsAll 56 patients had monocular onset, including 39 (69.6%, 39/56) males and 17 (30.4%, 17/56) females, 26 (46.4%, 26/56) with left eyes involved and 30 (53.6%, 30/56) with right eyes involved. Their average age was (25.0±24.4) years. Ocular trauma was the leading cause of streptococcal endophthalmitis (73.2%, 41/56), followed by ophthalmic surgery (23.2%, 13/56) and endogenous infection (3.6%, 2/56). The streptococcal species included Streptococcus viridans (50.0%, 28/56), Streptococcus pneumoniae (18/56, 32.1%) and β-hemolytic Streptococcus (17.9%, 10/56). The susceptibility rates of Streptococcus to penicillin, cefatriaxone, vancomycin and levofloxacin were 66.0%, 57.1%, 94.1% and 92.4%, respectively. Patients received PPV+IVI and IVI as initial treatment were 49 eyes (87.5%, 49/56) and 7 eyes (12.5%, 7/56), respectively. Vitreous injection of glucocorticoids were performed in 17 eyes (30.4%, 17/56); and systemic antibiotics were applied in 52 cases (92.9%, 52/56). At the final follow-up, 47 eyes were recorded with visual acuity. Twenty (35.7%, 20/56) had best corrected visual acuity (BCVA)≥0.05 and 27 (48.2%, 27/56) had BCVA ＜0.05, of which 1 (1.8%, 1/56) had an eyeball enucleation. The etiology of endophthalmitis, streptococcal species, initial treatment with PPV, vitreous injection of glucocorticoids, and systemic antibiotics did not significantly affect patients' visual outcomes (P＞0.05). Timely visit to the hospital after the onset of symptoms (≤3 days) was significantly associated with achieving a final BCVA above 0.05 (P=0.025). ConclusionsOcular trauma was the primary cause of streptococcal endophthalmitis. Streptococcus viridans is the most common pathogenic bacterium. Streptococci had high susceptibility to vancomycin, but patients' visual outcomes were poor.
Objective To systematically assess the efficacy and clinical significance of antibiotic prophylaxis in severe acute pancreatitis (SAP), so as to provide references for its rational clinical application. Methods For collecting the randomized controlled trials (RCTs) about antibiotic prophylaxis in SAP, a search was conducted in MEDLINE, EMbase, Cochrane Central Register of Controlled Trials, CBM and CNKI from the date of their establishment to August, 2010. After the clinical studies meeting the inclusive criteria were extracted and their quality was assessed. Meta-analysis was conduced by using RevMan 5.0 software. Results Twelve RCTs were included with a total of 777 patients. The results of Meta-analysis showed compared with the control group, the antibiotic prophylaxis group was not associated with a statistically significant reduction in mortality (RR=0.75, 95%CI 0.50 to 1.12), in the incidence of infected pancreatic necrosis (RR 0.82, 95%CI 0.63 to 1.09), in surgical interventions (RR=0.97, 95%CI 0.74 to 1.26), and in the incidence of nonpancreatic infections (RR=0.73, 95%CI 0.48 to 1.10). Conclusion Antibiotic prophylaxis for SAP does not reduce mortality, infected necrosis, or surgical intervention.

ObjectivesTo systematically review the efficacy of prophylactic antimicrobial use on preventing infections after arthroscopy.MethodsPubMed, EMbase, The Cochrane Library, CNKI, CBM and WanFang Data databases were electronically searched to collect clinical studies on the efficacy of prophylactic antimicrobial use on preventing infections after arthroscopy from January 1990 to September 2020. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies; then, meta-analysis was performed by using RevMan 5.3 software and Stata 15.0 software.ResultsA total of 8 retrospective cohort studies and 1 randomized controlled trial involving 60 136 subjects were included. The results of the meta-analysis showed that: there was no difference in the post-operational infection rate among patients with and without antimicrobial prophylaxis for arthroscopies (OR=0.51, 95%CI 0.25 to 1.04, P=0.06). For knee arthroscopies, the post-operational infection rate had no difference between patients with and without antimicrobial prophylaxis (OR=0.89, 95% CI 0.65 to 1.23, P=0.48). However, for shoulder arthroscopies, the post-operational infection rate in the antimicrobial prophylaxis group was significantly lower than that in the group without the antimicrobial prophylaxis(OR=0.18, 95%CI 0.08 to 0.37, P<0.000 01).ConclusionsCurrent evidence shows that there is no association between preoperative antimicrobial prophylaxis and a decreased infection rate for knee arthroscopies. Antimicrobial prophylaxis appears to lead to fewer infections after shoulder arthroscopies. Due to the limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
