Purpose To determine whether the use of mupirocin ointment for preoperative eradication of nasal bacterial carriage was effective in reducing conjunctival bacterial flora. (41%) in the control group (< .05). Even after povidone-iodine preparation, eight of 22 eyes (36%) in the control group demonstrated persistent positive cultures, whereas one (6.7%) of the treatment eyes exhibited growth (< .05). Conclusions Prophylactic use of mupirocin nasal ointment resulted in significant reduction of conjunctival 957116-20-0 IC50 flora with or without preoperative topical 5% povidone-iodine preparation. The use of mupirocin nasal ointment prior to intraocular surgery or intravitreal injections is a novel method for reducing conjunctival contamination rates, which theoretically should reduce the incidence of endophthalmitis. INTRODUCTION Bacterial endophthalmitis is a rare, but serious, complication of intraocular surgery. The reported incidence varies depending on the type of surgery, with culture-positive endophthalmitis in one study observed in 0.30% of secondary intraocular lens implantations and 0.051% of vitrectomy cases.1 A number of different sources have been implicated as origins of possible infection. Some of these include the eyelids, eyelashes, conjunctiva, and nasal secretions. One study demonstrated that organisms isolated through the vitreous had been indistinguishable from those retrieved through the eyelids genetically, conjunctiva, or nasal area in 14 of 17 instances of endophthalmitis.2 Gram-positive microorganisms 957116-20-0 IC50 are area of the regular flora of your skin, nares, and conjunctiva, and interestingly the Endophthalmitis Vitrectomy Research demonstrated that 94% of isolates recovered from eye with postoperative endophthalmitis had gram-positive microorganisms, 70% which were because of coagulase-negative staphylococci.3 Mupirocin (Bactroban) is a distinctive antibiotic that exerts bactericidal actions by interfering using the actions of isoleucyl-transfer RNA synthetase. Mupirocin can be energetic against gram-positive microorganisms, including and varieties. It is obtainable like a nose ointment and can be used for the eradication of methicillin-resistant was removed in 91% of colonized health care employees 2 to 4 times pursuing treatment with mupirocin ointment.5 Nose carriage of gram-positive organisms is a well-established risk factor for surgical site infections. In a big multicenter research of bacteremia, higher than 80% from the bloodstream isolates were similar to the people through the anterior nares.6 Perioperative elimination of nasal carriage using mupirocin ointment significantly decreased the surgical site infection price in a single research of cardiothoracic medical procedures individuals.7 Additionally, 957116-20-0 IC50 the usage of mupirocin nose ointment was effective in reducing the incidence of infections in hemodialysis individuals, as well as with those individuals who undergo continuous ambulatory peritoneal dialysis (CAPD).8,9 There is certainly evidence in the literature of nonophthalmologic specialties how the rates of surgical site infections could be decreased with mupirocin nasal ointment. Consequently, we wanted to see whether using mupirocin ointment to remove nose bacterial carriage ahead of intraocular medical procedures was effective in reducing conjunctival bacterial flora. If effective, we hypothesize that prices of postoperative endophthalmitis could possibly be decreased with improved sterilization from the ocular surface. METHODS The study was carried out with the approval of the University of Chicago School of Medicine Institutional Review Board. Thirty-seven adult patients, age range 26 to 83 years (57 14 years), undergoing elective cataract or pars plana vitrectomy surgery between November 2005 and April 2006 at the University of Chicago were included in this prospective, blinded, randomized study (Table). Exclusion criteria included the following: known sensitivity or allergy to any of the constituents of mupirocin ointment, active ocular infection at the time of surgery, or concurrent use of any antibiotic (systemic or topical). The 37 eyes in this study were randomized to either control or treatment groups. TABLE PATIENT Mouse monoclonal to CD64.CT101 reacts with high affinity receptor for IgG (FcyRI), a 75 kDa type 1 trasmembrane glycoprotein. CD64 is expressed on monocytes and macrophages but not on lymphocytes or resting granulocytes. CD64 play a role in phagocytosis, and dependent cellular cytotoxicity ( ADCC). It also participates in cytokine and superoxide release DEMOGRAPHICS WITH BREAKDOWN OF THOSE WHO DID NOT USE MUPIROCIN NASAL OINTMENT (CONTROL GROUP) AND THOSE WHO RECEIVED NASAL OINTMENT (TREATMENT GROUP) PRIOR TO 957116-20-0 IC50 OCULAR SURGERY After informed consent was obtained, 22 patients were enrolled in the control group and received no nasal medication. Fifteen patients were enrolled in the treatment group and were asked to self-administer mupirocin ointment to each nostril twice daily for 5 days prior to surgery (Figure 1). Nasal cultures were obtained in all patients using a cotton swab moistened with sterile balanced saline solution (BSS, Alcon Laboratories, Inc). In the treatment group, nasal cultures were obtained prior to the administration of mupirocin ointment. FIGURE 1 Technique for administering mupirocin nasal ointment prior to ocular surgery.
