Importance of Source Control in the Subgroup of Intra-Abdominal Infections for Septic Shock Patients: Analysis of 390 Cases.

Background: This study aimed to evaluate the epidemiology of septic shock (SS) associated with intraabdominal infections (IAI) as well as associated mortality and efficacy of early source control in a tertiary-care educational hospital. Methods: Patients who had SS with IAI and consulted by Infectious Diseases consultants between December 2013 and October 2022 during night shifts in our centre were analyzed retrospectively. Results: A total number of 390 patients were included. Overall, 30-day mortality was 42.5% on day 3, while day 14 and 30 mortality rates were 63.3% and 71.3%, respectively. Source control by surgical or percutaneous operation was performed in 123 of 390 cases (31.5%), and the mortality rate was significantly lower in cases that were performed source control at any time during SS (65/123-52.8% vs 213/267-79.8%, p<0.001). In 44 of 123 cases (35.7%), source control was performed during the first 12 hours, and mortality was significantly lower in this group versus others (24/44-54.5% vs 254/346-73.4%, p=0.009). On the other hand, female gender (p<0.001, odds ratio(OR)= 2.943, 95%CI=1.714-5.054), diabetes mellitus (p= 0.014, OR=2.284, 95%CI=1.179-4.424), carbapenem-resistant Gram-negative etiology (p=0.011, OR=4.386, 95%CI=1.398-13.759), SOFA≥10 (p<0.001, OR=3.036, 95%CI=1.802-5.114), lactate >3 mg/dl (p<0.001, OR=2.764, 95%CI=1.562-4.891) and lack of source control (p=0.001, OR=2.796, 95%CI=1.523-5.133) were significantly associated with 30-day mortality in logistic regression analysis. Conclusion: Source control has a vital importance in terms of mortality rates for IAI-related septic shock patients. Our study underscores the need for additional research, as the present analysis indicates that early source control does not manifest as a protective factor in logistic regression.

Carbapenem-resistant Gram-negative pathogens associated with septic shock: a review of 120 cases.

This study aimed to evaluate the influencing variables for outcomes in patients with septic shock having culture-proven carbapenem-resistant Gram-negative pathogens. It included 120 patients (mean age 64.29 ± 1.35 years and 58.3% female). The mean Sequential Organ Failure Assessment score during septic shock diagnosis was found to be 11.22 ± 0.43 and 9 ± 0.79 among the patients with mortality and among the survivors, respectively (P = 0.017). The logistic regression analysis showed that empirical treatment as mono Gram-negative bacteria-oriented antibiotic therapy (P = 0.016, odds ratio (OR) = 17.730, 95% confidence interval (CI): 1.728-182.691), Charlson Comorbidity Index >2 (P = 0.032, OR = 7.312, 95% CI: 5.7-18.3), and systemic inflammatory response syndrome score 3 or 4 during septic shock diagnosis (P = 0.014, OR = 5.675, 95% CI: 1.424-22.619) were found as independent risk factors for day 30 mortality. Despite early diagnosis and effective management of patients with septic shock, the mortality rates are quite high in CRGNP-infected patients.

Systematic review of Lyme disease in Turkey.

A systematic review was conducted with the aim of describing the demographical data, features and outcomes of patients with Lyme disease (LD), reported from Turkey. Three international database (electronic PubMed, Web of Science and Scopus) and two national database (Ulakbim and Turkmedline) searches were performed using the following keywords (['Lyme' or 'Borrelia burgdorferi' or 'Borrelia' or 'Borreliosis'] and 'Turkey [and/country]'). National Notifiable Diseases Surveillance System (NNNDS) of Centers for Disease Control and Prevention (CDC) criteria were used for classification. A PRISMA-based algorithm was used for systematic review. There were a total of 75 LD cases in 36 different reports. Studies related to LD are confined to case reports. We believe that LD is an important healthcare problem in Turkey and to our knowledge this is the first systematic review from this country.
