Antimicrobial Photodynamic Therapy in the Nasal Decolonization of Maintenance Hemodialysis Patients

The objective of this study will be to evaluate the effect of Antimicrobial Photodynamic Therapy (aPDT) in the Nasal Decolonization of Dialytic Chronic Renal Patients, Staphylococcus Aureus (S.aureus) Carriers This is a 3-months follow-up, randomized, single-blind, prospective controlled trial, single-center and will happen in 02 phases: Phase 1 - Epidemiological Evaluation - A researcher will invite the research participants who are undergoing treatment at the Hemodialysis Service of Clinical Hospital and explain its contents. After reading and signing the informed consent, this same researcher (calibrated for the experiment) will perform nasal secretion microbiological collections to identify patients colonized by S.aureus in the anterior nostril (nasal carrier) - baseline T0 and the application of the questionnaire that identifies possible factors that may be considered as risk for colonization and possible development of diseases related to S. aureus. In the laboratory of Microbiology, the strains will be identified and the colonized patients will be invited to continue the study (Phase 2). Non-carrier patients will only be counseled with infection prevention care. Phase 2 - Parallel clinical trial with two intervention groups (aPDT or Mupirocin) - Patients with nasal aureus (thirty-four colonized patients aged over 18 years) will be treated with aPDT (experimental group) or mupirocin (control group). A trained researcher will collect new aliquots of nasal discharge after completion of nostril treatment (T1) to check for decolonization by culture. A new collection will be performed at 1 (T2) and 3 (T3) months after treatment to assess recolonization. It was evaluated intervention safety (photodynamic therapy) through a directed and open questionnaire about adverse effects.
