Abstract
PURPOSE The clinical significance of negative toxin enzyme immunoassays (EIA) for Clostridioides difficile infections (CDIs) is unclear. Our study aimed to investigate the significance of toxin EIA-negative in the diagnosis and prognosis of CDI. METHODS All stool specimens submitted for C. difficile toxin EIA testing were cultured to isolate C. difficile. In-house PCR for tcdA, tcdB, cdtA, and cdtB genes were performed using C. difficile isolates. Stool specimens were tested with C. difficile toxins A and B using EIA kit (RIDASCREEN Clostridium difficile toxin A/B, R-Biopharm AG, Darmstadt, Germany). Characteristics and subsequent CDI episodes of toxin EIA-negative and -positive patients were compared. RESULTS Among 190 C. difficile PCR-positive patients, 83 (43.7%) were toxin EIA-negative. Multivariate analysis revealed independent associations toxin EIA-negative results and shorter hospital stays (OR = 0.98, 95% CI 0.96-0.99, p = 0.013) and less high-risk antibiotic exposure in the preceding month (OR = 0.38, 95% CI 0.16-0.94, p = 0.035). Toxin EIA-negative patients displayed a significantly lower white blood cell count rate (11.0 vs. 35.4%, p < 0.001). Among the 54 patients who were toxin EIA-negative and did not receive CDI treatment, three (5.6%) were diagnosed with CDI after 7-21 days without complication. CONCLUSION Our study demonstrates that toxin EIA-negative patients had milder laboratory findings and no complications, despite not receiving treatment. Prolonged hospitalisation and exposure to high-risk antibiotics could potentially serve as markers for the development of toxin EIA-positive CDI.

Antibiotics (Basel) 2024; 13:51. [PMID: 38247610 PMCID: PMC10812669 DOI: 10.3390/antibiotics13010051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Revised: 12/29/2023] [Accepted: 01/02/2024] [Indexed: 01/23/2024] Open
Abstract
Clostridioides difficile (C. difficile) is a predominant nosocomial infection, and guidelines for improving diagnosis and treatment were published in 2017. We conducted a single-center, retrospective 10-year cohort study of patients with primary C. difficile infectious disease (CDID) at the largest referral Lithuanian university hospital, aiming to evaluate the clinical and laboratory characteristics of CDID and their association with the outcomes, as well as implication of concordance with current Clinical Practice Guidelines. The study enrolled a total of 370 patients. Cases with non-concordant CDID treatment resulted in more CDID-related Intensive Care Unit (ICU) admissions (7.5 vs. 1.8%) and higher CDID-related mortality (13.0 vs. 1.8%) as well as 30-day all-cause mortality (61.0 vs. 36.1%) and a lower 30-day survival compared with CDID cases with concordant treatment (p < 0.05). Among cases defined by two criteria for severe CDID, only patients with non-concordant metronidazole treatment had refractory CDID (68.8 vs. 0.0%) compared with concordant vancomycin treatment. In the presence of non-concordant metronidazole treatment for severe CDID, only cases defined by two severity criteria had more CDID-related ICU admissions (18.8 vs. 0.0%) and higher CDID-related mortality (25.0 vs. 2.0%, p < 0.05) compared with cases defined by one criterion. Severe comorbidities and the continuation of concomitant antibiotics administered at CDID onset reduced (p < 0.05) the 30-day survival and increased (p = 0.053) 30-day all-cause mortality, with 57.6 vs. 10.7% and 52.0 vs. 25.0%, respectively. Conclusions: CDID treatment non-concordant with the guidelines was associated with various adverse outcomes. In CDID with leukocytes ≥ 15 × 109/L and serum creatinine level > 133 µmol/L (>1.5 mg/dL), enteral vancomycin should be used to avoid refractory response, as metronidazole use was associated with CDID-related ICU admission and CDID-related mortality. Severe comorbidities worsened the outcomes as they were associated with reduced 30-day survival. The continuation of concomitant antibiotic therapy increased 30-day all-cause mortality; thus, it needs to be reasonably justified, deescalated or stopped.

First Clostridioides difficile Recurrence Is Highest Following Concomitant Antimicrobial Administration During and Within 30 Days of Treatment. Dig Dis Sci 2023; 68:4221-4229. [PMID: 37665427 DOI: 10.1007/s10620-023-08091-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Accepted: 08/21/2023] [Indexed: 09/05/2023]
Abstract
BACKGROUND Clostridioides difficile infection (CDI) is an epidemic with the strongest risk factor being antibiotic usage. Patients who get CDI frequently require concomitant antibiotics for other indications around the time of their infection. AIMS To assess the recurrence of CDI (rCDI) in patients receiving concomitant antibiotics at the same time or shortly thereafter treatment of CDI. METHODS We retrospectively reviewed records for patients with their first inpatient CDI episode. Patients were grouped into those who didn't receive concomitant antibiotics (noABx), those receiving antibiotics at the same time as treatment of CDI (ABxDURING), those receiving antibiotics within 30-days of completion of CDI therapy (ABxAFTER) and those who received antibiotics both during and after CDI treatment (ABxDuringAfter). Our primary outcome was recurrence within 14-90 days; other outcomes included ICU stay at the time of diagnosis, 30-day ICU transfer, 30-day colectomy, and readmission. RESULTS 457 patients had CDI during admission (mean age: 66.4 years, 51.9% female). 64.1% were exposed to concomitant antibiotics. Recurrence rates were 4.3%, 6.1%, 13.8% and 19.1%, for noABx, ABxDURING, ABxAFTER and ABxDuringAfter, respectively. Patients with ABxDuringAfter had the highest rates of rCDI when compared to noABx [OR 5.67, 95% CI (2.18-14.72)]. CONCLUSIONS There is a high rate of utilization of non-CDI antibiotics during or shortly after completing CDI treatment with high rates of recurrence within 90-days. Concomitant antimicrobials alter the opportunity for the microbiota to re-grow and worsens dysbiosis leading to increases in recurrence. Concomitant antimicrobial stewardship remains important in patients being treated for CDI and shortly after treatment.

INFECTIOUS DISEASES 2022; 22:e336-e340. [PMID: 35617982 DOI: 10.1016/s1473-3099(22)00274-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Revised: 01/16/2022] [Accepted: 04/20/2022] [Indexed: 06/15/2023]
Abstract
Antibiotics are modifiable risk factors for Clostridioides difficile infection (CDI), driving pathogenesis via gut microbiome disruption. The management of patients with CDI prescribed concomitant non-CDI antibiotics is problematic and influences CDI outcome and recurrence risk. Though an assessment of the ongoing requirement for concomitant antibiotics is essential, discontinuation is often not possible. Antibiotics for other reasons might also need to be commenced during CDI therapy. Attempts to minimise the number and duration of antibiotics with a change to a low-risk class are recommended. Fidaxomicin might be preferable to vancomycin due to it having less effect on the gut microbiome; however, vancomycin is also acceptable. Metronidazole should be avoided and proton pump inhibitors discontinued. Access to fidaxomicin might be limited; hence, it should be prioritised for patients at high risk of recurrence. There is insufficient evidence to support extending anti-CDI therapy duration and concerns regarding microbiome effect remain. The addition of bezlotoxumab might be considered if multiple additional risk factors for recurrent CDI exist, though the amount of evidence is low. Investigational approaches to reduce the effect of concomitant antibiotics on the gut microbiome could further optimise CDI treatment in the presence of concomitant antibiotic use in the future.

Validation of Clinical Risk Models for Clostridioides difficile -Attributable Outcomes. Antimicrob Agents Chemother 2022; 66:e0067622.

Abstract
Clostridioides difficile is the leading health care-associated pathogen, leading to substantial morbidity and mortality; however, there is no widely accepted model to predict C. difficile infection severity. Most currently available models perform poorly or were calibrated to predict outcomes that are not clinically relevant. We sought to validate six of the leading risk models (Age Treatment Leukocyte Albumin Serum Creatinine (ATLAS), C. difficile Disease (CDD), Zar, Hensgens, Shivashankar, and C. difficile Severity Score (CDSS)), guideline severity criteria, and PCR cycle threshold for predicting C. difficile-attributable severe outcomes (inpatient mortality, colectomy/ileostomy, or intensive care due to sepsis). Models were calculated using electronic data available within ±48 h of diagnosis (unavailable laboratory measurements assigned zero points), calibrated using a large retrospective cohort of 3,327 inpatient infections spanning 10 years, and compared using receiver operating characteristic (ROC) and precision-recall curves. ATLAS achieved the highest area under the ROC curve (AuROC) of 0.781, significantly better than the next best performing model (Zar 0.745; 95% confidence interval of AuROC difference 0.0094–0.6222; P = 0.008), and highest area under the precision-recall curve of 0.232. Current IDSA/SHEA severity criteria demonstrated moderate performance (AuROC 0.738) and PCR cycle threshold performed the worst (0.531). The overall predictive value for all models was low, with a maximum positive predictive value of 37.9% (ATLAS cutoff ≥9). No clinical model performed well on external validation, but ATLAS did outperform other models for predicting clinically relevant C. difficile-attributable outcomes at diagnosis. Novel markers should be pursued to augment or replace underperforming clinical-only models.

Abstract
The risk of metronidazole treatment failure in Clostridium difficile infection (CDI) patients with chronic kidney disease (CKD) or end-stage renal disease in Korea has not been established. We evaluated 481 patients who had been admitted to two secondary hospitals with a diagnosis of, and treatment for, CDI during 2010–2016. CDI patients were divided into three groups according to CKD status: non-CKD (n = 363), CKD (n = 55) and those requiring dialysis (n = 63). Logistic regression analyses were performed to examine the association of CKD status with treatment failure. CDI patients receiving dialysis tended to have increased odds of metronidazole and overall treatment failure compared to non-CKD patients; adjusted odds ratios and 95% confidence intervals were 2.09 (1.03–4.21) and 2.18 (1.11–4.32) for metronidazole and overall treatment failure, respectively. However, CKD patients did not have increased odds of metronidazole or overall treatment failure compared to non-CKD patients, even where severe CDI was more prevalent in CKD patients. The incidence of symptomatic ileus or toxic megacolon did not differ among groups. Our results suggest that initial metronidazole therapy may be considered in CDI patients with non-dialysis CKD, but should not be considered in CDI patients undergoing dialysis.
