Characteristics, Risk Factors, and Prevalence of Clostridioides difficile Among Hospitalized Patients in a Tertiary Care Hospital in Palestine.

PURPOSE: Clostridioides difficile is one of the most important nosocomial infection pathogens. It is linked with many risk factors. Unfortunately, many studies have been conducted in different countries to address the Clostridioides difficile infections (CDI), and no studies have been conducted in Palestine. This study aims to identify the prevalence and possible risk factors associated with CDI. PATIENTS AND METHODS: This was a retrospective descriptive study conducted at the An-Najah National University Hospital (NNUH) in Palestine. Data were collected for patients diagnosed with CDI who tested positive for GDH, toxins A and B between January 2018 and April 30, 2021. In addition, patient characteristics and risk factors associated with CDI were analyzed. RESULTS: A total of 593 participants were included in the study; 53% had hospital-acquired CDI. There was an insignificant association between participant age and CDI risk. Most patients had mild to moderate infections. Sixty-three percent of the participants were immunocompromised. About 58.5% used an antibiotic agent two weeks before CDI, and 67% were on a proton pump inhibitor (PPI). About 61.3% of patients were treated according to IDSA 2017 guidelines, and 94% responded adequately to the treatment provided. CONCLUSION: There was an increased prevalence of community-acquired CDI, with a prevalence almost equal to that of hospital-acquired. In addition, most of the participants were immunocompromised. The risk factors for CDI, such as antibiotics and PPI use, were also observed with high prevalence among positive patients. Antimicrobial stewardship and the appropriate use of acid suppressors are warranted.

Trends in Clostridium difficile infection and risk factors for hospital acquisition of Clostridium difficile among children with cancer.

OBJECTIVES: To study the trend of Clostridium difficile infection (CDI) and risk factors for hospital acquired CDI (HA-CDI) among children with cancer. STUDY DESIGN: We analyzed 33 095 first pediatric hospitalizations for malignancy among 43 pediatric hospitals between 1999 and 2011. The effect of demographics, disease characteristics, and weekly drug exposure (antibiotics, antacids, and chemotherapy) on HA-CDI was assessed with multivariate Cox regression. CDI was defined by the combination of International Classification of Diseases, 9th edition-Clinical Modification (ICD-9CM), CDI diagnostic assay billing code, and concurrent administration of a CDI-active antibiotic. HA-CDI was defined as CDI with assay occurring after the sixth hospital day. RESULTS: A total of 1736 admissions with CDI were identified, of which 380 were HA-CDI. CDI incidence increased from 1999-2006 (P = .01); however, CDI testing frequency and disease decreased from 2006-2010 (P < .05). Admissions with HA-CDI had longer lengths of stay compared with those without HA-CDI (35 days vs 12 days, P < .01) and greater risk of inpatient mortality (relative risk 2.3, P < .01). Increased risk of HA-CDI (hazard ratio [95% CI]) was seen after exposure to the following drugs: aminoglycoside (1.357 [1.053-1.749]), third generation cephalosporin (1.518 [1.177-1.959]), cefepime (2.383 [1.839-3.089]), and proton pump inhibiting agent (1.398 [1.096-1.784]) in the prior week, and chemotherapy (1.942 [1.491-2.529]) in the 8-14 days prior to HA-CDI onset. Histamine-2 receptor antagonist exposure in the prior week was associated with decreased risk of HA-CDI (0.730 [0.584-0.912]). CONCLUSIONS: Despite an apparent decrease in CDI incidence from 2006-2010, HA-CDI remains prevalent and morbid among children with cancer. Recent exposure to chemotherapy, proton pump inhibitor, and certain antibiotics were independent risk factors for HA-CDI.
