Screening for Candida auris in patients admitted to eight intensive care units in England, 2017 to 2018

Background Candida auris is an emerging multidrug-resistant fungal pathogen associated with bloodstream, wound and other infections, especially in critically ill patients. C. auris carriage is persistent and is difficult to eradicate from the hospital environment. Aim We aimed to pilot admission screening for C. auris in intensive care units (ICUs) in England to estimate prevalence in the ICU population and to inform public health guidance. Methods Between May 2017 and April 2018, we screened admissions to eight adult ICUs in hospitals with no previous cases of C. auris, in three major cities. Swabs were taken from the nose, throat, axilla, groin, perineum, rectum and catheter urine, then cultured and identified using matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI-TOF MS). Patient records were linked to routine ICU data to describe and compare the demographic and health indicators of the screened cohort with a national cohort of ICU patients admitted between 2016 and 2017. Results All C. auris screens for 921 adults from 998 admissions were negative. The upper confidence limit of the pooled prevalence across all sites was 0.4%. Comparison of the screened cohort with the national cohort showed it was broadly similar to the national cohort with respect to demographics and co-morbidities. Conclusion These findings imply that C. auris colonisation among patients admitted to ICUs in England is currently rare. We would not currently recommend widespread screening for C. auris in ICUs in England. Hospitals should continue to screen high-risk individuals based on local risk assessment.

Recent Emergence

Abstract Background Recent emergence of Candida auris as a multidrug resistant fungal pathogen, is a serious concerns for public health. However, there is a paucity of reported cases from Oman. Literature search resulted in finding only 7 cases from Oman, reporting C. auris infections in the articles first published in 2017. However, the rate of isolatin is increasing. Methods In this study, we included the results of all positive blood cultures of C. auris in Suhar teaching hospital from May 2018 (date of first detection) till end of April 2019. Further confirmation of the species was performed by MALDI-TOF and antibiotic susceptibility test (AST) by Vitek 2 in central public health laboratory (CPHL) of Oman. Results We detected 13 patients (9 females, 4 males). The mean age was 58.61% years (28–76 years). All candidemic patients had serious underlying conditions, including prolonged hospital stay or extensive and prolonged antimicrobial exposure or medical comorbidities (8 of 13). The time from hospital admission to onset of C. auris candidemia was 8–49 days, with a median of approximately 27 days. The most common isolated co- pathogen from blood culture was K. pneumonia (without regard to Coagulase-negative staphylococci). As average, every patient received 4.8 kind of different antibiotics in mean 88 doses before candidemia developed and piperacillin–tazobactam was the most common used antibiotics. AST was done just for 5 patients and revealed high-level resistance to fluconazole and Amphotricin B while, Echinocandins (anidulafungin, caspofungin) were fully sensitive and voricunazole had intermediate sensitivity. Mean duration of anti-fungal treatment was 12.5 days (5 – 26 days). 8 patients treated by Echinocandins (4/8 died), 4 by Fluconazole (3/4 died) and one without treatment discharged. 30-day all-cause mortality was 61.5%. Conclusion In Oman, C. auris has been reported from many hospitals. Resistance to several antifungal agents and persistence in the hospital environment make this organism a potential menace for the treating physician and the infection control personnel. In our hospital, every candidemic patient should be treated with Echinocandins and assumed to be resistant to Fluconazole until proven otherwise according to results of AST.

Abstract Background Chlorhexidine digluconate (CHG), the most widely used antiseptic, has recently been applied to patient washing to decolonize the multidrug-resistant organisms (MDROs), but there are little data on susceptibilities of MDROs to CHG. The purpose of this study was to evaluate CHG resistance among MDROs before and after the intervention of daily CHG bathing in adult intensive care units (ICUs). Methods The intervention of daily body washing with 2% CHG cloths were taken in adult patients the medical or surgical ICU of 23-bed by a crossover manner for 6 months (MICU, July to December 2017; SICU, January to June 2018) in a 1,050-bed, university hospital in the Republic of Korea. Available MDRO isolates were randomly selected from clinical cultures of ICU patients within 6 months before, during and after the intervention, including MRSA, MR-CoNS, VRE, Carbapenem-resistant Pseudomonas aeruginosa (CR-PA), CR-Acinetobacter baumannii (CR-AB). Minimum inhibitory concentrations (MICs) were determined using the broth microdilution method set by the Clinical Laboratory Standards Institute. Determination of the minimum bactericidal concentrations (MBCs) was performed by subculturing 10 µL from each well without visible microbial growth. Cumulative amounts of CHG used in both ICUs was estimated across the study period from January 2008 to June 2018. Results The cumulative CHG consumption from both ICUs increased sharply from 27,503 g to 29,556 g after one-year intervention. The ranges of MICs and MBCs of CHG among MDRO clinical isolates selected by a 6-month phase are summarized in Table 1. Particularly, CR-PA and CR-AB isolates revealed four to eight times higher MICs and MBCs compared with the majority of Gram-positives excepting some VRE isolates. On the other hand, neither MICs and MBCs ranges of CHG from the MDRO isolates nor the monthly incidence of the MDROs from both ICUs were significantly increased before and after the intervention of daily CHG bathing. Conclusion This study indicates that some Gram-negative MDRO isolates with higher MICs and MBCs of CHG might be from longstanding exposure to CHG or efflux pumps. Although 2% daily CHG bathing uses over 1,000 times higher concentrations than the lethal concentration, it might be needed to monitor CHG resistance among MDROs.

Tract Infections

Background: Lower respiratory tract infections are one of the most common infections among the patients in Intensive Care Units (ICUs). Admission in ICUs and use of life supporting devices increase the risk of infection with multidrug resistant pathogens. Aims and Objectives: This study was aimed to determine the prevalence and antibiograms ofthe bacterial pathogens causing lower respiratory tract infectionsamong patients of ICUs. Materials and Methods: A total of 184 specimens from patients admitted in ICUswith lower respiratory tract infections were included in this study. Isolation, identification and antibiotic susceptibility testing of the isolates was performed by standard microbiological techniques. Carbapenamase detection was performed by modified Hodge test method.Detection of metallo beta lactamase (MBL) was tested by imipenem and imipenem/EDTA disc. Detection of Klebsiellapneumoniaecarbapenamase (KPC) was performed by imipenem and imipenem/phenyl boronic acid. Results: Out of 184 samples, 131 showed significant growth of bacterial pathogens. Acinetobacter species (42.6%), Staphylococcus aureus (16.9%) and Pseudomonasaeruginosa(13.9%)were the three most common isolates. Out of 22 imipenem resistant isolates of Acientobacter species, 9 were KPC producer, 4 were MBL producers and 3 isolates were positive for MBL and KPC both. Among the Acinetobacter species, 5.1% isolates were resistant to tigecycline and colistin. One isolate of Pseudomonas aeruginosa was positive for MBL. Conclusions:High prevalence of multidrug resistant bacteria in ICUs was recorded. Gram negative bacilli were predominantly associated with LRTI among ICU patients;Acinetobacterspecies being most common isolate. Detection of carbapenamase among the Acinetobacterand emergence of tigecycline resistancelimits the therapeutic options.Regular monitoring of such resistant isolates would be important for managing infection control in critical units.

Health Care Associated Infections

Antibiotic-resistant pathogens and nosocomial infections constitute common and serious problems for neonates admitted to neonatal intensive care units worldwide. Chryseobacterium indologenes is a non-lactose-fermenting, gram-negative, health care-associated pathogen (HCAP). It is ubiquitous and intrinsically resistant to several antibiotics. Despite its low virulence, C. indologenes has been widely reported to cause life-threatening infections. Patients on chronic immunosuppressant drugs, harboring invasive devices and indwelling catheters become the nidus for C. indologenes. Typically, C. indologenes causes major health care-associated infections such as pneumonia, empyema, pyelonephritis, cystitis, peritonitis, meningitis, and bacteremia in patients harboring central venous catheters. Management of C. indologenes infection in neonates is not adequately documented owing to underreporting, particularly in India. Because of its multidrug resistance and the scant availability of data from the literature, the effective empirical treatment of C. indologenes is challenging. We present an uncommon case of bacteremia caused by C. indologenes in a preterm newborn baby with moderate respiratory distress syndrome who was successfully treated. We also provide a review of infections in the neonatal age group. Henceforth, in neonates receiving treatments involving invasive equipment use and long-term antibiotic therapy, multidrug resistant C. indologenes should be considered an HCAP.
