It has approximately 2,000 beds and is divided into 6 buildings. The dermatology unit has 20 beds, which are distributed across 10 rooms of one, two, or four beds each. This unit is used for the hospitalization of patients with severe dermatologic conditions. On average, there are 30 admissions per month and 4,500 patient-days each year.</p><span id="cesec30" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle80">Surveillance cultures of patients</span><p id="para40" class="elsevierStylePara elsevierViewall">Over a period of 26 weeks that began on May 31, 2005, weekly surveillance cultures for MRSA were obtained from all of the patients admitted to the unit. These samples were collected from the anterior nares and skin lesions. Patients who were positive for MRSA were not followed for further surveillance cultures. Patients who were negative for MRSA were cultured weekly until their discharge from the unit.</p><p id="para50" class="elsevierStylePara elsevierViewall">Due to the high proportion of patients who tested positive on the first surveillance culture, patients were cultured upon admission and then weekly from the 13th week of the study onward.</p><p id="para60" class="elsevierStylePara elsevierViewall">The swabs from the anterior nares were collected by introducing a swab into the nasal vestibulum and then rubbing with light pressure. The swabs were transported in sterile tubes containing culture medium and were sent immediately to the laboratory for further processing and analysis.

Through the enforcement of these measures, we expected to halt the nosocomial transmission of MRSA. Community-acquired MRSA (CA-MRSA) has been rarely described in Brazil and has been shown to occur mainly in the southern region of the country<a class="elsevierStyleCrossRefs" href="#bib19">19,20</a> near the border with Uruguay, which is a country in which CA-MRSA is a significant problem. In addition, in a previous study of MRSA isolates obtained from bloodstream infections,<a class="elsevierStyleCrossRef" href="#bib21">21</a> there were six cases of hospital-acquired MRSA bacteremia the dermatology unit. Thus, we expected most of the cases of MRSA colonization to be hospital acquired. However, in our dermatology unit, we observed that approximately half of the colonization cases were hospital-acquired and that a significant proportion of patients were positive for MRSA at the time of admission. Our results suggest that many patients are colonized by community-acquired MRSA or are colonized at other healthcare facilities and may be a source of MRSA transmission to other patients in the hospital. There was a significantly higher proportion of patients with pemphigus and other bullous diseases among MRSA carriers, which suggested that disseminated bullous disease is a risk factor for MRSA colonization.</p><p id="para370" class="elsevierStylePara elsevierViewall">During the entire study period, nosocomial transmission of MRSA occurred as well as admission of colonized patients. This likely generated or increased colonization pressure and made control more difficult despite the efforts directed to prevent nosocomial MRSA transmission. Over the six-month study period, the frequency of nosocomial-acquired cases tended to decrease, but the colonization pressure increased from 13% to 59%. We attributed this decrease in the nosocomial acquisition of MRSA to the extensive efforts of the staff, which included improving the isolation conditions and the infection control measures. Our original goal was the complete eradication of nosocomial transmission, but this goal was not achieved. The colonization pressure was first evaluated for vancomycin-resistant enterococci.<a class="elsevierStyleCrossRef" href="#bib22">22</a> This type of resistance has been studied in MRSA and has been shown to play a role as a risk factor for nosocomial transmission.<a class="elsevierStyleCrossRef" href="#bib23">23</a> In one study, a colonization pressure above 30% led to a 5-fold increase in the risk of MRSA colonization.<a class="elsevierStyleCrossRef" href="#bib24">24</a></p><p id="para380" class="elsevierStylePara elsevierViewall">Due to the large number of patients who are colonized at the time of admission, the use of routine surveillance cultures and the placement of colonized patients into cohorts may not affect the rates of colonization unless all patients are immediately placed under contact precautions even before the surveillance cultures are analyzed. Furthermore, the success of MRSA control that is based mainly on the identification of carriers through the analysis of surveillance cultures depends on the sensitivity of these cultures, which may not be sufficiently high to detect all colonized patients. Some authors have reported that the lack of throat culturing may lead to an underestimation of the percentage of MRSA carriers by as much as 8 to 18%.<a class="elsevierStyleCrossRefs" href="#bib25">25,26</a></p><p id="para390" class="elsevierStylePara elsevierViewall">The clinical impact and the relevance of routine patient culturing may be contested because, despite a high proportion of colonized patients, there were only two cases of bloodstream infection in our six-month study period. Routine culturing and the use of patient cohorts and private rooms for positive patients are expensive and labor-intensive measures. In our hospital, most rooms are meant to hold two or four patients, and there are very few private rooms. During patient isolation, the rooms are not used at full capacity, which is a problem because there is a nationwide shortage of hospital beds. In addition, although the carriage of <span class="elsevierStyleItalic">S. aureus</span> is considered a risk factor for the development of infection,<a class="elsevierStyleCrossRef" href="#bib10">10</a> one prospective study found that nasal colonization with MRSA was a poor predictor of the subsequent occurrence of MRSA respiratory tract or bloodstream infection.<a class="elsevierStyleCrossRef" href="#bib27">27</a></p><p id="para400" class="elsevierStylePara elsevierViewall">This study also addressed the role of HCWs in the transmission of MRSA. Among HCWs, MRSA was observed in 15% of the cultures. Only three HCWs were positive on both occasions, but two HCWs harbored different molecular types of MRSA at each culture, suggesting transient carriage. Interestingly, half of the HCWs who were positive for MRSA harbored isolates of subtypes that were not present among the patients. This result suggests that a large proportion of the HCW colonizations were acquired outside of the hospital, either in the community or at other institutions.</p><p id="para410" class="elsevierStylePara elsevierViewall">MRSA with SCC<span class="elsevierStyleItalic">mec</span> type III was multidrug resistant and belonged to the Brazilian Endemic Clone (BEC). Molecular typing by pulsed-field gel electrophoresis (PFGE) revealed three different types and one predominant type (79%). Within this predominant type, there were nine different subtypes. The BEC has been endemic in Brazil for more than a decade.<a class="elsevierStyleCrossRef" href="#bib28">28</a> During this time, it is likely that changes occurred that made Tenover's criteria<a class="elsevierStyleCrossRef" href="#bib17">17</a> inadequate to interpret its clonality. In this situation, multilocus sequence typing (MLST) is more useful because it evaluates seven housekeeping genes that are more stable over time.<a class="elsevierStyleCrossRef" href="#bib29">29</a> BEC presents as sequence type ST-239,<a class="elsevierStyleCrossRef" href="#bib28">28</a> and all of the SCC<span class="elsevierStyleItalic">mec</span> type III isolates tested in our study also belonged to this ST.</p><p id="para420" class="elsevierStylePara elsevierViewall">The presence of MRSA with SCC<span class="elsevierStyleItalic">mec</span> type IV at our hospital is a more recent phenomenon than the existence of the BEC. Therefore, the PFGE typing reflected clonality that was similar although not identical to the MLST.<a class="elsevierStyleCrossRef" href="#bib21">21</a> Furthermore, we expected that the SCCmec type IV would be mainly community acquired. However, similar to other geographic areas,<a class="elsevierStyleCrossRef" href="#bib30">30</a> it seems as though this type has crossed hospital borders and circulates not only in the community but also in the hospital environment.</p><p id="para430" class="elsevierStylePara elsevierViewall">As observed in other studies conducted at our hospital,<a class="elsevierStyleCrossRefs" href="#bib21">21,31</a> SCCmec type IV MRSA isolates from dermatologic patients did not express the Panton-Valentine leukocidin (PVL) virulence factor. The <span class="elsevierStyleItalic">tst</span> gene was also absent from all of the isolates. This finding is interesting because PVL-producing clones have been associated with skin and soft tissue infections<a class="elsevierStyleCrossRefs" href="#bib32">32,33</a> and because TSST-1 is the cause of skin lesions. On the other hand, in a hospital environment, where patients are severely ill and have many diseases, a virulent strain of <span class="elsevierStyleItalic">S. aureus</span> would probably not be successful because it would cause severe infection and high mortality, as it does in the community.</p><p id="para440" class="elsevierStylePara elsevierViewall">Our study has limitations. First, it was our original intention to use the CDC definitions, but the necessary information was not available for a large proportion of the included patients. Because of this lack of information, we had to introduce the “indeterminate” category. There was a large proportion of patients for which the origin of colonization was deemed indeterminate, which was in part due to the fact that surveillance culturing immediately upon admission was only initiated halfway into the study. In addition, we did not observe SCC<span class="elsevierStyleItalic">mec</span> types other than types I to IV, and there were a few isolates for which we could not determine the type. Finally, it was not possible to perform MLST analyses on each of the PFGE subtypes.</p><p id="para450" class="elsevierStylePara elsevierViewall">In summary, almost half of the dermatology patients in this study were colonized by MRSA at the time of hospital admission or acquired MRSA while in the hospital. Half of the nosocomial MRSA cases were SCC<span class="elsevierStyleItalic">mec</span> type IV. Nosocomial MRSA colonization continued throughout the study period despite the identification of colonized patients, the use of contact precautions and patient cohorting or the placement of patients in private rooms based on their surveillance cultures. Colonization pressure continuously increased during the study period, which may partly explain the difficulty in controlling the spread of MRSA. Pemphigus and other bullous diseases were significantly associated with MRSA colonization. The healthcare workers were predominantly colonized by SCC<span class="elsevierStyleItalic">mec</span> type IV MRSA, and this colonization was found to be transient and predominantly community acquired.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:7 [ 0 => array:2 [ "identificador" => "xpalclavsec1582406" "titulo" => "KEYWORDS" ] 1 => array:2 [ "identificador" => "cesec10" "titulo" => "INTRODUCTION" ] 2 => array:3 [ "identificador" => "cesec20" "titulo" => "METHODS" "secciones" => array:7 [ 0 => array:2 [ "identificador" => "cesec30" "titulo" => "Surveillance cultures of patients" ] 1 => array:2 [ "identificador" => "cesec40" "titulo" => "Definitions" ] 2 => array:2 [ "identificador" => "cesec50" "titulo" => "Control measures" ] 3 => array:2 [ "identificador" => "cesec60" "titulo" => "Surveillance cultures of healthcare workers (HCWs)" ] 4 => array:2 [ "identificador" => "cesec70" "titulo" => "Ethics" ] 5 => array:2 [ "identificador" => "cesec80" "titulo" => "Analysis of data" ] 6 => array:3 [ "identificador" => "cesec90" "titulo" => "Microbiological methods" "secciones" => array:5 [ 0 => array:2 [ "identificador" => "cesec100" "titulo" => "Detection of MRSA" ] 1 => array:2 [ "identificador" => "cesec110" "titulo" => "Susceptibility testing" ] 2 => array:2 [ "identificador" => "cesec120" "titulo" => "Molecular typing" ] 3 => array:2 [ "identificador" => "cesec130" "titulo" => "SCCmec typing" ] 4 => array:2 [ "identificador" => "cesec140" "titulo" => "Detection of genes for virulence factors" ] ] ] ] ] 3 => array:2 [ "identificador" => "cesec150" "titulo" => "RESULTS" ] 4 => array:2 [ "identificador" => "cesec160" "titulo" => "DISCUSSION" ] 5 => array:2 [ "identificador" => "xack639316" "titulo" => "ACKNOWLEDGMENTS" ] 6 => array:1 [ "titulo" => "REFERENCES" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2011-07-03" "fechaAceptado" => "2011-08-29" "PalabrasClave" => array:1 [ "en" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "KEYWORDS" "identificador" => "xpalclavsec1582406" "palabras" => array:5 [ 0 => "Transmission" 1 => "Surveillance culture" 2 => "Molecular typing" 3 => "MRSA" 4 => "Hospital infection" ] ] ] ] "tieneResumen" => true "resumen" => array:1 [ "en" => array:2 [ "resumen" => "<span id="ceabs10" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle10">OBJECTIVE:</span><p id="spara110" class="elsevierStyleSimplePara elsevierViewall">The aim of this study was to characterize <span class="elsevierStyleItalic">Staphylococcus aureus</span> (MRSA) carriage in a dermatology unit.</p></span> <span id="ceabs20" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle20">METHODS:</span><p id="spara120" class="elsevierStyleSimplePara elsevierViewall">This was a prospective and descriptive study.
