mupirocin and Candidiasis

Urinary tract infections (UTIs) are common health-care-associated infections. Bacteriuria commonly precedes UTI and is often treated with antibiotics, particularly in hospital intensive care units (ICUs). In 2013, a cluster-randomised trial (REDUCE MRSA Trial [Randomized Evaluation of Decolonization vs Universal Clearance to Eradicate MRSA]) showed that body surface decolonisation reduced all-pathogen bloodstream infections. We aim to further assess the effect of decolonisation on bacteriuria and candiduria in patients admitted to ICUs.. We did a secondary analysis of a three-group, cluster-randomised trial of 43 hospitals (clusters) with patients in 74 adult ICUs. The three groups included were either meticillin-resistant Staphylococcus aureus (MRSA) screening and isolation, targeted decolonisation (screening, isolation, and decolonisation of MRSA carriers) with chlorhexidine and mupirocin, and universal decolonisation (no screening, all patients decolonised) with chlorhexidine and mupirocin. Protocol included chlorhexidine cleansing of the perineum and proximal 6 inches (15·24 cm) of urinary catheters. ICUs within the same hospital were assigned the same strategy. Outcomes included high-level bacteriuria (≥50 000 colony forming units [CFU]/mL) with any uropathogen, high-level candiduria (≥50 000 CFU/mL), and any bacteriuria with uropathogens. Sex-specific analyses were specified a priori. Proportional hazards models assessed differences in outcome reductions across groups, comparing an 18-month intervention period to a 12-month baseline period.. 122 646 patients (48 390 baseline, 74 256 intervention) were enrolled. Intervention versus baseline hazard ratios (HRs) for high-level bacteriuria were 1·02 (95% CI 0·88-1·18) for screening or isolation, 0·88 (0·76-1·02) for targeted decolonisation, and 0·87 (0·77-1·00) for universal decolonisation (no difference between groups, p=0·26), with no sex-specific reductions (HRs for men: 1·09 [95% CI 0·85-1·40] for screening or isolation, 1·01 [0·79-1·29] for targeted decolonisation, and 0·78 [0·63-0·98] for universal decolonisation, p=0·12; HRs for women: 0·97 [0·80-1·17] for screening and isolation, 0·83 [0·70-1·00] for targeted decolonisation, and 0·93 [0·79-1·09] for universal decolonisation, p=0·49). HRs for high-level candiduria were 1·14 (0·95-1·37) for screening and isolation, 0·99 (0·83-1·18) for targeted decolonisation, and 0·83 (0·70-0·99) for universal decolonisation (p=0·05). Differences between sexes were due to reductions in men in the universal decolonisation group (HRs: 1·21 [95% CI 0·88-1·68] for screening or isolation, 1·01 [0·73-1·39] for targeted decolonisation, and 0·63 [0·45-0·89] for universal decolonisation, p=0·02). Bacteriuria with any CFU/mL was also reduced in men in the universal decolonisation group (HRs 1·01 [0·81-1·25] for screening or isolation, 1·04 [0·83-1·30] for targeted decolonisation, and 0·74 [0·61-0·90] for universal decolonisation, p=0·04).. Universal decolonisation of patients in the ICU with once a day chlorhexidine baths and short-course nasal mupirocin could be a potential preventive strategy in male patients because it significantly decreases candiduria and any bacteriuria, but not for women..

To assess the efficacy and clinical outcome of 2% mupirocin in a polyethylene glycol base and nystatin cream as treatment regimens in diaper candidosis.. A prospective randomized comparative study.. In vitro. The susceptibility of 20 clinical isolates of Candida albicans to 2% mupirocin, nystatin, and five additional antifungal agents was evaluated using the Nathan agar-well diffusion assay. The minimum inhibitory concentration (MIC) of mupirocin against the Candida species was determined using a tube dilution method. In vivo. Twenty patients (mean age, 12 months; range, 1 month to 4 years) with moderate to severe Monilia diaper dermatitis either had mupirocin ointment or nystatin cream applied to the infected area every 8 h or after every diaper change for a period of 7 days. Microscopic examination of skin scrapings and mycologic and microbiological cultures were performed before treatment and daily for 7 days, and progress was clinically assessed.. In vitro. Topical mupirocin produced a greater zone of inhibition than nystatin cream, i.e. a mean of 27.2 mm (SD 1.55) compared with a mean of 17.3 mm (SD 1.08) for nystatin cream. MIC for mupirocin of 512 microg/mL in one case, 256 microg/mL in six cases, 200 microg/mL in 10 cases and 400 microg/mL in three cases were obtained for the 20 clinical isolates. C. albicans also displayed a universal sensitivity to mupirocin and nystatin. In vivo. Eradication of all Candida organisms was achieved within 2-6 days (mean, 2.6 days) in 10 patients receiving topical mupirocin therapy with rapid healing of the excoriated wounds (mean, 4.7 days). Both Gram-positive and Gram-negative bacteria were eradicated from the infected area within the trial period. Ten patients received topical nystatin cream and, in each case, Candida was successfully cleared within 5 days (mean, 2.8 days). Only three wounds were clinically healed within the trial period, however. The remaining seven wounds showed evidence of improved, but ongoing excoriated dermatitis and a heavy growth of polymicrobial organisms.. Both agents eradicated Candida, the major difference being the marked response of the diaper dermatitis to mupirocin. Mupirocin should be applied topically 3-4 times daily or with each diaper change and is an excellent antifungal agent.
