Perception of quality of life in people experiencing or having experienced a Clostridioides difficile infection: a US population survey.

ABSTRACT: BACKGROUND:Although the incidence, severity and mortality of Clostridioides (Clostridium) difficile infection (CDI) have been increasing, patients' quality of life changes resulting from CDI have not been studied thoroughly. This study aimed at exploring the consequences of CDI on quality of life through patients' perspective. METHODS:An observational, cross-sectional study involving 350 participants with a self-reported CDI diagnosis was conducted through an online self-administered survey. Participants were grouped into those who had active disease ("Current CDI") and those who had a history of CDI ("Past CDI"). RESULTS:One hundred fifteen participants (33%) reported Current CDI and 235 (67%) reported Past CDI. A large majority of participants admitted that their daily activities were impacted by the infection (93.9% and 64.7% of Current and Past CDI respondents respectively, p?

Project description:BackgroundThe health-related quality of life (HrQoL) can be substantially affected in patients with recurrent Clostridioides difficile infection (rCDI) but the impact of effective treatment of the infection remains unclear. This study aimed to evaluate the HrQoL in patients with rCDI and estimate the gain in HrQoL associated with effective treatment of rCDI.MethodsPatients' HrQoL was estimated based on EuroQol 5-Dimensions 3-Levels (EQ-5D-3L) questionnaires obtained from a Danish randomised controlled trial (RCT). In the RCT, 64 patients with rCDI were randomised to receive either vancomycin (n = 16), fidaxomicin (n = 24) or faecal microbiota transplantation (FMT) preceded by vancomycin (n = 24). The primary outcome in the RCT was rCDI resolution. Patients were closely monitored during the RCT, and rescue FMT was offered to those who failed their primary treatment. Patients' HrQoL was measured at baseline and at 8- and 26-weeks follow-up. Linear regression analyses conditional on the differences between baseline and follow-up measurements were used to assess statistical significance (p < 0.05).ResultsWithin 26 weeks of follow-up, 13 (81%) patients treated with vancomycin, 12 (50%) patients treated with fidaxomicin, and 3 (13%) patients treated with FMT had a subsequent recurrence and received a rescue FMT. The average HrQoL for untreated patients with rCDI was 0.675. After receiving effective treatment, this value increased by 0.139 to 0.813 (p < 0.001) at week 8 and by 0.098 to 0.773 (p = 0.003) at week 26 of follow-up compared with baseline.ConclusionThe HrQoL was adversely affected in patients with an active episode of rCDI but increased substantially after receiving an effective treatment algorithm in which rescue FMT was provided in case of a primary treatment failure.Trial registrationThe RCT was preregistered at EudraCT (j.no. 2015-003004-24, https://www.clinicaltrialsregister.eu/ctr-search/trial/2015-003004-24/results) and at ClinicalTrials.gov (study identifier NCT02743234, https://clinicaltrials.gov/ct2/show/NCT02743234).

Project description:The response to iron limitation of several bacteria is regulated by the ferric uptake regulator (Fur). The Fur-regulated transcriptional, translational and metabolic networks of the Gram-positive, pathogen Clostridioides difficile were investigated by a combined RNA sequencing, proteomic, metabolomic and electron microscopy approach. At high iron conditions (760 g/l) the C. difficile fur mutant displayed a growth deficiency compared to wild type C. difficile cells. Several iron transporters were found induced by Fur regulation during low iron (11 g/l) conditions. The major adaptation to low iron conditions was observed for the central energy metabolism. Most ferredoxin-dependent amino acid fermentations were found significantly down regulated (had, etf, acd, grd, trx, bdc, hbd). The substrates of these pathways phenylalanine, leucine, glycine and some initial intermediates (phenylpyruvate, oxo-isocaproate, 3-hydroxy-butanoyl-CoA, crotonyl-CoA) were found accumulated, while some end product like isocaproate and butanoate were found reduced. Flavodoxin (fldX) formation and riboflavin biosynthesis (rib) were found enhanced, most likely to replace the missing ferredoxins. Proline reductase (prd), the corresponding ion pumping RNF complex (rnf) and the reaction product 5-aminovalerate were significantly enhanced. An ATP forming ATPase (atpCDGAHFEB,) of the F0F1-type was found induced while the formation of a V-type, mostly proton-pumping, ATP-consuming ATPase (atpDBAFCEKI, was decreased. The [Fe-S] enzyme-dependent pyruvate formate lyase (pfl), formate dehydrogenase (fdh) and hydrogenase (hyd) branch of glucose utilization and glycogen biosynthesis (glg) were significantly reduced, leading to an accumulation of glucose and pyruvate. The formation of [Fe-S] enzyme carbon monoxide dehydrogenase (coo) was inhibited. An intensive remodeling of the cell wall was observed most likely to increase antibiotic resistance. Polyamine biosynthesis (spe) was found induced leading to an accumulation of spermine, spermidine and putrescine. The fur mutant lost most of its flagella. Finally, the CRISPR/Cas and a prophage encoding operon were downregulated. Fur binding sites were found upstream of 20 of the regulated genes. Overall, adaptation to low iron conditions in C. difficile focused on an increase of iron import, significant decrease in metabolic iron utilization and protection during the complex transition.
