Abstract
Introduction Infections in haemodialysis (HD) patients are an important cause of morbidity, hospitalization, and mortality. Patients undergoing HD are more prone to develop bacterial infections by multidrug-resistant organisms (MDROs). Objectives This study is aimed to detect MDROs colonization in HD patients and its associated risk factors and outcome. Methodology A total of 62 nasal swabs and 124 rectal swabs were collected from 62 patients coming to the haemodialysis unit from of March to May 2021 and were further screened for MRSA, VRE and CRE. Results Out of 62 patients, 22.59% showed the presence of methicillin-resistant staphylococcus aureus (MRSA) while VRE was present in four patients (4/62). CRE was found as 24.2% (15/62). Duration of dialysis was found as a significant risk factor-associated MRSA carriage, Whereas Charlson index and drug and medication were found as significant risk factor for VRE carriage. Discussion & Conclusion HD patients are particularly vulnerable to life threatening infections. Therefore, continuous epidemiological surveillance for these MDROs, including genotypic analysis and implementation of adequate decolonization strategies, is crucial and will reduce the possibility of autoinfection as well as disrupt transmission of multi-resistant isolates to others.

Abstract
Chronic kidney disease (CKD) is now a global epidemic, and the prevalence is increasing worldwide. Hemodialysis is one of the ways to treat by kidney function replacement. Infection is the number two cause of death in patients with hemodialysis (HD). Methicillin-resistant Staphylococcus aureus (MRSA) is a common cause of bacteriemia in patients with dialysis. The epidemiological data of MRSA carriers in CKD in Indonesia are still scarce. This study was to determine the prevalence of MRSA carriers in patients at The Kidney and Hypertension Outpatient-clinic and Hemodialysis Installation at Dr. Soetomo Academic General Hospital, Surabaya Indonesia. The study design was descriptive-analytic with a cross- sectional study design. Sampling was collected consecutively. Data on the general characteristics of the research subjects will be analyzed using a Chi-Squared test. There were 150 CKD stage five patients included in this study, the number of patients has MRSA carrier were 6 (4%), among them, subjects underwent HD MRSA carrier were 2 subjects(2.7%), while for non-HD patients with MRSA were 4 subjects (5.3 %). There were no significant differences in MRSA carriers between HD and non HD groups (p=0.404). Comorbid factors that accompany MRSA carriers are diabetes mellitus, hypertension, kidney stones, gout, and systemic lupus erythematosus (SLE). This study found, there were no significant differences in the incidence of MRSA carriers in stage five CKD non HD or HD groups. MRSA colonization exists in stage five CKD sufferers, so awareness of MRSA colonization

Abstract
Staphylococcus aureus is an important infectious agent in hemodialysis patients. This study was conducted to determine the frequency of S. aureus nasal carriage in hemodialysis patients (HD) and health-care workers (HCW) at the main dialysis center of Bam city, located in southeast of Iran. In this cross-sectional study, a total of 52 nasal swabs were obtained from health-care workers and hemodialysis patients to detect methicillin-sensitive S. aureus (MSSA) isolates. The resistance to different antibacterial agents was determined by disk diffusion method. Also, Panton-Valentine Leukocidin (PVL) - encoding gene as well as Staphylococcal protein A (spa) type were determined. The nasal carriage rate of S. aureus was found to be 24.4% and 18.8% in patients on hemodialysis and health-care workers, respectively. Among identified isolates, no methicillin-resistant S. aureus (MRSA) was found. Only two MSSA isolates (16.7%) were resistant to trimethoprim/sulfamethoxazole. One isolate (8.6%) was positive for pvl gene. Moreover, 8 spa types were found. According to BURP analysis, six out of the 12 S. aureus isolates (50%) belonged to the same clone, indicating a prevalence of a major clone among MSSA in carriage, including patients and HCW. Mupirocin is still the appropriate drug for reducing nasal colonization in our setting. Accumulation of isolates from patients and staff in one spa clonal complex is alarming for the necessity of more serious infection control in this center. Therefore, it is necessary to screen patients and health-care workers as a health priority, in order to prevent cross transmission.

Abstract
BACKGROUND Patients on dialysis are particularly vulnerable to meticillin-resistant Staphylococcus aureus (MRSA) infections and MRSA colonization is associated with increased risk for severe infections in this population. AIM Determination of risk factors for MRSA colonization among dialysis patients. METHODS This is a systematic review and meta-analysis of studies reporting risk factors of MRSA colonization. We performed a PubMed and EMBASE literature search to identify all studies on risk factors for MRSA colonization among patients undergoing dialysis treatment. Previous hospitalization, type of dialysis access, comorbid conditions, dialysis vintage, gender, length of time on dialysis, and previous antibiotic use were extracted and assessed for possible association with MRSA colonization in this population. FINDINGS Ten out of 8252 articles, presenting data on 2364 dialysis patients, were included. We found that hospitalization within the previous 12 months [odds ratio (OR): 1.93; 95% confidence interval (CI): 1.04-3.58] and the use of temporary dialysis access (relative risk: 1.66; 95% CI: 1.06-2.60) were associated with a significantly higher risk of MRSA colonization. MRSA carriage was associated with lower serum albumin levels compared to non-carriage (OR: 0.8; 95% CI: 0.68-0.95) and was higher among patients with chronic lung disease (OR: 2.16; 95% CI: 1.04-4.51). There were no data on patients undergoing peritoneal dialysis. CONCLUSION Active surveillance approaches, including potential decolonization strategies, are suggested to focus on these subgroups of haemodialysis patients with hospitalization within the previous year, temporary dialysis access, lower serum albumin levels, and chronic lung disease comorbidity.

Abstract
Patients undergoing dialysis are particularly vulnerable to methicillin-resistant Staphylococcus aureus (MRSA) infections. We performed a meta-analysis of published studies to estimate the prevalence of MRSA colonization in dialysis patients, time trends, and long-term risk of subsequent MRSA infections. Our search of the PubMed and Embase databases returned 5743 nonduplicate citations, from which we identified 38 relevant studies that included data on 5596 dialysis patients. The estimated prevalence of MRSA colonization was 6.2% (95% confidence interval [95% CI], 4.2% to 8.5%). The prevalence increased over time but remained stable after 2000. Stratification of patients according to dialysis modality and setting revealed that 7.2% (95% CI, 4.9% to 9.9%) of patients on hemodialysis were colonized with MRSA compared with 1.3% (95% CI, 0.5% to 2.4%) of patients on peritoneal dialysis (P=0.01), and that a statistically significant difference existed in the percentage of colonized inpatients and outpatients (14.2% [95% CI, 8.0% to 21.8%] versus 5.4% [95% CI, 3.5% to 7.7%], respectively; P=0.04). Notably, the risk of developing MRSA infections increased among colonized hemodialysis patients compared with noncolonized patients (relative risk, 11.5 [95% CI, 4.7 to 28.0]). The long-term (6-20 months) probability of developing a MRSA infection was 19% among colonized hemodialysis patients compared with only 2% among noncolonized patients. In summary, 6.2% of dialysis patients are MRSA colonized, and the average prevalence of colonization has remained stable since 2000. Colonization in hemodialysis patients is associated with increased risk of MRSA infection.

Abstract
Background Nasal colonization with methicillin-resistant Staphylococcus aureus (MRSA) is a well defined risk factor for subsequent bacteremia and death in various groups of patients, but its impact on outcome in patients receiving long-term hemodialysis (HD) is under debate. Methods This prospective interventional cohort study (performed 2004 to 2010) enrolled 289 HD outpatients of an urban dialysis-unit. Nasal swab cultures for MRSA were performed in all patients upon first admission, at transfer from another dialysis facility or readmission after hospitalisation. Nasal MRSA carriers were treated in a separate ward and received mupirocin nasal ointment. Concomitant extra-nasal MRSA colonization was treated with 0.2% chlorhexidine mouth rinse (throat) or octenidine dihydrochloride containing antiseptic soaps and 2% chlorhexidine body washes (skin). Clinical data and outcome of carriers and noncarriers were systematically analyzed. Results The screening approach identified 34 nasal MRSA carriers (11.7%). Extra-nasal MRSA colonization was observed in 11/34 (32%) nasal MRSA carriers. History of malignancy and an increased Charlson Comorbidity Index were significant predictors for nasal MRSA carriers, whereas traditional risk factors for MRSA colonization or markers of inflammation or malnutrition were not able to discriminate. Kaplan-Meier analysis demonstrated significant survival differences between MRSA carriers and noncarriers. Mupirocin ointment persistently eliminated nasal MRSA colonization in 26/34 (73.5%) patients. Persistent nasal MRSA carriers with failure of this eradication approach had an extremely poor prognosis with an all-cause mortality rate >85%. Conclusions Nasal MRSA carriage with failure of mupirocin decolonization was associated with increased mortality despite a lack of overt clinical signs of infection. Further studies are needed to demonstrate whether nasal MRSA colonization represents a novel predictor of worse outcome or just another surrogate marker of the burden of comorbid diseases leading to fatal outcome in HD patients.

Abstract
Staphylococcus aureus, which has its ecological niche in the anterior nares, has been shown to cause a variety of infectious diseases mainly for patients in hemodialysis units. We performed this study to evaluate the prevalence of nasal S. aureus carriage among hemodialysis outpatients, to determine the antimicrobial susceptibility of isolates, to characterize the virulence genes, and to identify associated risk factors. Nares swab specimens were obtained from 70 outpatients on hemodialysis between March and June 2010. Samples were plated immediately onto S. aureus specific media and pattern of antibacterial sensitivity was determined using disk diffusion method. Polymerase chain reaction was used to detect nuc, mecA, and genes encoding staphylococcal toxins. Medical record of patients was explored to determine S.aureus carriage risk factors. Nasal screening identified 42.9% S. aureus carriers with only one (3.3%) methicillin-resistant S. aureus isolate. Among the methicillin-susceptible S. aureus isolates, high rate of penicillin resistance (81.8%) has been detected. The identified risk factors were male gender and age ≤ 30 years. Research of virulence factors showed a high genetic diversity among the 30 S. aureus isolates. Twenty-one (70%) of them had at least one virulence gene, of which 3.3% were Panton-Valentine leukocidin (lukS/F-PV) genes. S. aureus carriage must be screened for at regular intervals in hemodialysis patients. Setting up a bacterial surveillance system is one of the strategies to understand the epidemiology of methicillin-resistant S. aureus, to guide local antibiotic policy and prevent spread of antibiotic-resistant S. aureus.
