AI Article Synopsis
- The study analyzed Clostridioides difficile infections (CDIs) and recurrences (rCDIs) from 2015 to 2019 in Germany, utilizing health insurance data.
- A total of 15,402 CDI episodes were recorded; 77% of patients were aged 65 or older, and the incidence of CDI decreased by 38% during the study period.
- Despite the decline, rCDIs occurred in 19% of patients, significantly increasing the risk of complications such as sepsis and colectomy with each additional recurrence.
Article Abstract
Background: This real-world study assessed the epidemiology and clinical complications of Clostridioides difficile infections (CDIs) and recurrences (rCDIs) in hospital and community settings in Germany from 2015 - 2019.
Methods: An observational retrospective cohort study was conducted among adult patients diagnosed with CDI in hospital and community settings using statutory health insurance claims data from the BKK database. A cross-sectional approach was used to estimate the annual incidence rate of CDI and rCDI episodes per 100,000 insurants. Patients' demographic and clinical characteristics were described at the time of first CDI episode. Kaplan-Meier method was used to estimate the time to rCDIs and time to complications (colonic perforation, colectomy, loop ileostomy, toxic megacolon, ulcerative colitis, peritonitis, and sepsis). A Cox model was used to assess the risk of developing complications, with the number of rCDIs as a time-dependent covariate.
Results: A total of 15,402 CDI episodes were recorded among 11,884 patients. The overall incidence of CDI episodes declined by 38% from 2015 to 2019. Most patients (77%) were aged ≥ 65 years. Around 19% of CDI patients experienced at least one rCDI. The median time between index CDI episode to a rCDI was 20 days. The most frequent complication within 12-months of follow-up after the index CDI episode was sepsis (7.57%), followed by colectomy (3.20%). The rate of complications increased with the number of rCDIs. The risk of any complication increased by 31% with each subsequent rCDI (adjusted hazard ratio [HR]: 1.31, 95% confidence interval: 1.17;1.46).
Conclusions: CDI remains a public health concern in Germany despite a decline in the incidence over recent years. A substantial proportion of CDI patients experience rCDIs, which increase the risk of severe clinical complications. The results highlight an increasing need of improved therapeutic management of CDI, particularly efforts to prevent rCDI.

Article Synopsis
- The study aimed to assess infection risks and characteristics in multiple myeloma patients receiving new therapies, involving 155 patients from a hospital over 5 years.
- The analysis identified 242 infection episodes, predominantly clinically defined infections, with lower respiratory tract being the most affected area.
- Key risk factors for developing infections included having advanced disease (ISS stage III), receiving multiple lines of treatment, and being frail.
Background: The most severe complications of antibiotic use are clostridial infection (CDI) and pseudomembranous colitis (PMC). There is a need for further study of these conditions and identification of their triggers.
Aim: To identify risk factors for severe forms of antibiotic-associated diarrhea caused by .

Background/objectives: , an anaerobic bacillus ubiquitous in nature, is the leading cause of hospital-acquired diarrhoea and one of the main causes of mortality by nosocomial infections. We aimed to identify the main predictors of the risk of dying and the characteristics of a three-year cohort of patients hospitalised in our clinic that eventually had an unfavourable outcome.
Methods: We collected retrospectively available data for all patients hospitalised between January 1, 2021, and December 31, 2023.
