Acticoat (Smith and Nephew, Istanbul, Turkey), chlorhexidine acetate 0.5%, and silver sulfadiazine 1% were compared to assess the antibacterial effect of their application on experimental burn wounds in contaminated with Pseudomonas aeruginosa in rats. All treatment modalities were effective against P. aeruginosa because there were significant differences between treatment groups and control groups. The mean eschar concentrations did not differ significantly between Acticoat and chlorhexidine acetate groups, but there were significant differences between the silver sulfadiazine group and the other treatment groups, indicating that silver sulfadiazine significantly eliminated P. aeruginosa more effectively in the tissues than did the other two agents. All treatment modalities were sufficient to prevent the P. aeruginosa from invading to the muscle and from causing systemic infection. In conclusion, silver sulfadiazine is the most effective agent in the treatment of the P. aeruginosa-contaminated burn wounds; Acticoat can be considered as a treatment choice because of its peculiar ability of limiting the frequency of replacing wound dressings. 相似文献

The addition of 1% chlorhexidine digluconate to 1% silver sulfadiazine cream (CDSS) was compared with 1% silver sulfadiazine (SS) alone to assess the antibacterial effect of a once-daily application of the therapies on an experimental rat model with a 20% full-thickness burn wound seeded with 10(8) microorganisms originally isolated from infected wounds of burn patients. Separate series evaluated Staphylococcus aureus, Pseudomonas aeruginosa, Enterobacter cloacae, and Streptococcus faecalis. The mean concentration of all four organisms recovered after one week from biopsy specimens of full-thickness eschar was less in the CDSS-treated animals compared with the SS-treated animals. Microbial invasion into subjacent muscle was less frequent in animals seeded with S faecalis, while the mean concentration of bacteria recovered from muscle of animals seeded with S aureus and E cloacae was less in animals treated with CDSS compared with those treated with SS (P less than 0.05). The addition of 1% chlorhexidine digluconate to 1% silver sulfadiazine increased the antibacterial effectiveness of the latter agent. 相似文献

Wound bacterial colonization in 118 patients treated with chlorhexidine digluconate 0.2% in silver sulfadiazine 1% applied daily to the burn wounds was compared to that of 135 comparable patients similarly treated with silver sulfadiazine 1%. With chlorhexidine digluconate 0.2% in silver sulfadiazine 1%, colonization by Staphylococcus aureus was less frequent (38%) than with silver sulfadiazine (54%, p = 0.016). No statistical difference was found for colonization by Enterococcus faecalis, Pseudomonas aeruginosa, or Enterobacter cloacae. Washing of the wounds of 65 patients with chlorhexidine gluconate 4% during daily dressing changes was associated with reduced wound colonization by S. aureus (35% versus 51%, p = 0.03) and P. aeruginosa (8% versus 16%, p = 0.08) when compared to the 188 washed with nonantibacterial soap. Chlorhexidine, whether added to the topical agent silver sulfadiazine (chlorhexidine digluconate 0.2%) or in the bath soap (chlorhexidine gluconate 4%), decreased colonization by S. aureus. 相似文献

Leukopenia in non-septic burn patients receiving topical 1% silver sulfadiazine cream therapy: a survey 总被引:1,自引:0,他引:1
The cause of early postburn leukopenia (EPBL) is unknown. The evidence suggests that treating burn wounds with 1% silver sulfadiazine cream (SSD) is contributory, but that other factors exist, possibly including burn stress. Differences of opinion exist as to whether SSD applications to the wounds of non-septic burn patients should be discontinued if EPBL develops. A survey of opinion in 101 North American burn treatment facilities and a review of the literature show a strengthening of the perception that EPBL, whether caused by SSD or not, holds little risk for the burn patient. The majority of burn patients are now being assigned to treatment strategies in which the onset of EPBL requires discontinuance of SSD only at WBC counts lower than 2,000/cu mm or not at all. This is significantly lower (p less than .02) than the mean of the values recorded in the literature. There is now substantial experience with continuing the SSD therapy in this setting regardless of the WBC count. No complications are reported therefrom. 相似文献

Combined topical use of silver sulfadiazine and antibiotics as a possible solution to bacterial resistance in burn wounds 总被引:2,自引:0,他引:2
The superior efficacy of quinolones (norfloxacin, pefloxacin, and enoxacin) in controlling burn wound infections signals the discovery of new topical agents. However, there are a few reports on the emergence of resistant mutants to quinolones. Since attempts to develop AgSD resistant strains in vitro were unsuccessful and the emergence of AgSD resistance in vivo is a rare occurrence, we decided to investigate if the combined use of AgSD with other effective antibiotics, especially quinolones, would minimize the development of resistant bacteria. Our in vitro results indicate that when Ps. aeruginosa cultures were serially transferred 10 times through subinhibitory concentrations of norfloxacin, pefloxacin, etc., the MIC increased 40 times while when the cultures were passed through a combination of AgSD and these quinolones, the MIC of quinolones increased only tenfold. In vivo, when burned mice infected with either AgSD sensitive or resistant Ps. aeruginosa strains were treated with a topical cream containing 10mM silver sulfadiazine and 5mM norfloxacin or 5mM pefloxacin, the mortality was much lower than that of 10mM silver sulfadiazine alone or 5mM quinolones alone. Thus, combined use of silver sulfadiazine and quinolones appears to diminish the ability of Ps. aeruginosa strains to form resistant mutants. Furthermore, when the combination is used as a topical agent in burn wounds, lesser amounts of the individual drug are needed to control infection thereby reducing the toxic effects, if any, associated with these drugs. This combination does not in any way interfere with the antifungal or antibacterial properties of these individual drugs. 相似文献

The in-vitro activities of the topical agents azelaic acid, nitrofurazone, silver sulphadiazine and mupirocin have been determined against 80 strains of MRSA collected from worldwide sources. MICs were determined by agar dilution (with an inoculum of approximately 5.0 x 10(5) cfu) in Iso-Sensitest agar, and MBCs were measured by replica-plating from MIC plates using velvet pads. The agents tested were uniformly active against MRSA, mupirocin being the most active (MIC50 0.15 mg/L) followed by nitrofurazone (MIC50 19 mg/L), silver sulphadiazine (MIC50 85 mg/L) and azelaic acid (MIC50 850 mg/L). Concentrations of azelaic acid, nitrofurazone and silver sulphadiazine close to the MIC were bactericidal, but mupirocin was only bactericidal at concentrations substantially greater than the MIC. In time-kill experiments, azelaic acid and nitrofurazone were gradually bactericidal, silver sulphadiazine was rapidly bactericidal and mupirocin was not bactericidal. Silver sulphadiazine killed sulphonamide-sensitive and sulphonamide-resistant strains equally rapidly. No resistant mutants were found to azelaic acid, nitrofurazone or silver sulphadiazine in an inoculum of 10(9) cfu, but two strains yielded (frequency: 1.0 x 10(-9)) mutants resistant to mupirocin. Our in-vitro results suggest azelaic acid, nitrofurazone and silver sulphadiazine could be of use for clearing staphylococcal carriage. 相似文献

Mupirocin is a topically applied drug that is very active in the eradication of nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA). However, studies designed to compare mupirocin treatment with other antimicrobial regimens are lacking. We therefore conducted an open, prospective, randomized, controlled trial to compare the efficacy and safety of mupirocin versus those of oral co-trimoxazole plus topical fusidic acid (both regimens with a clorhexidine scrub bath) for the eradication of MRSA from nasal and extranasal carriers of MRSA. The eradication rates with mupirocin and co-trimoxazole plus fusidic acid at 2, 7, 14, 21, 28, and 90 days were 93 and of 93, 100 and 100, 97 and 94, 100 and 92, 96 and 95, and 78 and 71%, respectively, for nasal carriage. At 7, 14, and 28 days the eradication rates for extranasal carriage by the two regimens were 23 and 74, 83 and 76, and 45 and 69%, respectively. The efficacies and safety of both regimens were similar. The MRSA isolates were not resistant to the study drugs either at the baseline or at follow-up. These results suggest that mupirocin and co-trimoxazole plus fusidic acid, both used in conjunction with a chlorhexidine soap bath, are equally effective and safe for the eradication of MRSA from nasal and extranasal MRSA carriers. Mupirocin was easier to use but was more expensive. 相似文献

One percent silver sulfadiazine has been commonly used as a topical antimicrobial agent after a burn injury. Incidence of burn wound colonization by Staphylococcus aureus in patients treated with silver sulfadiazine has spurred research for other agents. A topical preparation that contains zinc and sulfadiazine (Zad-G) was evaluated for in vitro antibacterial spectrum and in vivo efficacy. Muscle biopsy specimens of rats treated with Zad-G appear to have fewer colonies of S. aureus than groups treated with silver sulfadiazine. Topical therapy with Zad-G for patients with burns was comfortable, reduced wound infection, and was comparable to therapy with silver sulfadiazine. A topical Zad-G preparation that contains zinc sulfadiazine appears to be an effective alternative to silver sulfadiazine in the treatment of burn wounds. 相似文献

Introduction
Burns are widespread in the developed world, and expensive burn dressings are not universally available. Most burn patients suffer from a partial thickness burn that can be treated conservatively. Nevertheless, the ideal dressing for the burn wound has not been identified. We performed an animal experiment to compare the healing of partial thickness burns treated with silver sulfadiazine (SSD) and olive oil.Methods
A randomized controlled animal experiment was conducted on 3 anesthetized domestic pigs in which 51 partial thickness burns were created using a metal bar heated to 400°C and applied to the dorsum of the animals for 20 seconds. The burns were treated every other day with SSD cream (n = 16), purified olive oil (n = 20), or no topical therapy at all (n = 15). Assessment of wound healing was done by drawing and scanning the margins of the wound at the endpoint of the experiment. The remaining open wound area was then calculated using Scion Image version beta 4.0.2 (Scion, Frederick, Md), and the results were analyzed using a 1-way ANOVA test.Results
Burns treated with SSD healed faster than control burns (P < .05). There were no differences in the healing rates of wounds treated with olive oil versus controls or SSD. There were no wound infections in any of the 3 study groups.Conclusions
Treatment of partial thickness burns with purified olive oil did not result in faster healing when compared with SSD or dry gauze in a porcine model. 相似文献12.

XF-73 is a dicationic porphyrin drug with rapid Gram-positive antibacterial activity currently undergoing clinical trials for the nasal decolonization of Staphylococcus aureus, including methicillin-resistant Staphylococcus aureus (MRSA). In multistep (55-passage) resistance selection studies in the presence of subinhibitory concentrations of XF-73, retapamulin, mupirocin, fusidic acid, and vancomycin against four Network on Antimicrobial Resistance in Staphylococcus aureus MRSA strains, there was no >4-fold increase in the MIC for XF-73 after 55 passages. In contrast, there was an increase in the MICs for retapamulin (from 0.25 μg/ml to 4 to 8 μg/ml), for mupirocin (from 0.12 μg/ml to 16 to 512 μg/ml), for fusidic acid (from 0.12 μg/ml to 256 μg/ml), and for vancomycin (from 1 μg/ml to 8 μg/ml in two of the four strains tested). Further investigations using S. aureus NRS384 (USA300) and daptomycin demonstrated a 64-fold increase in the MIC after 55 passages (from 0.5 μg/ml to 32 μg/ml) with a >4-fold increase in the MIC obtained after only five passages. Sequencing analysis of selected isolates confirmed previously reported point mutations associated with daptomycin resistance. No cross-resistance to XF-73 was observed with the daptomycin-resistant strains, suggesting that whereas the two drugs act on the bacterial cell membrane, their specific site of action differs. XF-73 thus represents the first in a new class of antibacterial drugs, which (unlike the comparator antibiotics) after 55 passages exhibited a ≤4-fold increase in MIC against the strains tested. Antibacterial drugs with a low propensity for inducing bacterial resistance are much needed for the prevention and treatment of multidrug-resistant bacteria both within and outside the hospital setting. 相似文献

Carriers of methicillin-resistant Staphylococcus aureus (MRSA) in hospital constitute a reservoir of infections and increase the risk of bacteremia and wound infection. In this prospective randomized trial, we tested the effectiveness of oral fusidic acid for eradication of MRSA colonization. From March 1997 through February 1998, patients with MRSA colonization in medical intensive care units in a large urban teaching hospital were randomly assigned to receive fusidic acid 500 mg q8h orally for 7 days or no anti-staphylococcal treatment. Twenty-three MRSA carriers were found during the study period and 16 were eligible for evaluation; six of them received fusidic acid. MRSA colonization was cleared in only two of the six patients with fusidic acid treatment, and later recurred in one of them. MRSA disappeared for 1, 2, 7, 7, and 8 weeks, respectively, in five of the 10 patients without treatment. MRSA persisted in the other five cases. Although all MRSA isolates found in the initial surveillance culture were susceptible to fusidic acid (MIC = 2 microg/mL), seven isolates from two patients after fusidic acid treatment demonstrated high fusidic acid resistance (MIC 64 to >/= 256 microg/mL). Pulsed-field gel electrophoresis pattern analysis showed that the resistant strains were genetically identical to the susceptible strains isolated from the same patient before fusidic acid treatment, in both cases. However, genetically distinct strains colonized in the same individual during follow-up were found in four out of 16 cases. We conclude that oral fusidic acid alone is not suitable for eradication of MRSA colonization, and may lead to the emergence of resistant strains. 相似文献

Objectives
This work was conducted to study the prophylactic efficacy of 2 topical antibiotic ointments (mupirocin and nitrofurazone) against wound infection in experimental contaminated crush wounds.Methods
Male Wistar rats underwent two 2-cm incisions at the back side and randomized into 3 groups—placebo (n = 14), mupirocin (n = 14), and nitrofurazone (n = 14)—and infected with either Staphylococcus aureus or S pyogenes. All wound edges were crushed for 5 seconds with hemostats to simulate crush injury before inoculation of the microorganisms. Half of the wounds were sutured and the other half left open. These wounds were treated 3 times daily for 6 days with topical mupirocin, nitrofurazone, or petrolatum (as placebo). At the end of 6 days, excisional biopsies were taken from wound edges and histopathologic assessments were made based on neutrophilic infiltration, edema formation, myofibroblastic proliferation, and granulation tissue formation. For the microbiologic assessments, quantitative tissue cultures were made.Results
In S aureus-inoculated wounds, mupirocin showed higher antibacterial activity against bacterial colonization and reduced infection rates compared to placebo groups. The same effect was observed for the infection rates in S pyogenes-inoculated wounds. In S pyogenes-inoculated open wounds, nitrofurazone showed higher antibacterial activity against infection, but this effect was not observed in closed wounds. In S pyogenes- and S aureus-infected wounds, mupirocin treatment significantly lowered infection rates compared to nitrofurazone treatment. Histopathologic examination showed higher myofibroblastic proliferation and higher volume of granulation tissue in the nitrofurazon groups compared to the mupirocin groups.Conclusion
Topical mupirocin application was effective against crush wound infections inoculated with S pyogenes and S aureus. Nitrofurazone provides better granulation tissue formation, but did not effectively prevent bacterial colonization and infection in crush contaminated wounds. 相似文献15.

Wound care is painful for the patient with a burn injury and tedious for the burn unit staff but necessary to remove exudates and debris and to limit infections. In an effort to circumvent daily dressing changes while ensuring optimal wound protection, Sildimac (Marion Laboratories, Kansas City, Mo.), a new drug delivery system for silver sulfadiazine, was developed. When silver sulfadiazine, a topical antimicrobial commonly used for the treatment of burns, is incorporated into the delivery system, the drug is released in a sustained fashion. We report here the results of a multicenter evaluation of the safety and efficiency of Sildimac for treatment of full-thickness burn wounds. Sildimac, when left in place for up to 4 days, appears to be as effective as twice-daily wound cleansing and application of Silvadene cream 1% (Marion Laboratories, Kansas City, Mo.) for the treatment of full-thickness burns. 相似文献

The effect of topical application of silver sulfadiazine cream on the natural killer (NK) cell cytotoxicity was studied in a rat model of thermal injury. The rats were given a 30% total body surface area scald injury and the NK cell cytotoxicity was studied in rats at different days postinjury with or without treatment with silver sulfadiazine. The NK cell activity was observed to be significantly (P less than .0025) suppressed at day 7 postinjury in nontreated burned rats compared with control sham burned animals. Interestingly, in rats treated with silver sulfadiazine twice daily, no suppression in NK cell activity was observed. The application of base cream (without silver sulfadiazine) did not have any significant effect on the NK cell activity in burned rats. The data show that the effect of silver sulfadiazine on NK cell activity may be due to the sulfadiazine component, since the serum levels of sulfadiazine (33.7 +/- 1.9 micrograms/dL) were observed to be maximal at day 7 postinjury. 相似文献

Topical antimicrobial therapy has the potential to limit the mortality and morbidity of contaminated battlefield injuries. Many agents available are ill-suited for use on the battlefield; however, mafenide acetate solution (MAS) has known efficacy as a burn dressing adjunct, and previous work with mafenide as a direct chemotherapeutic has shown promise. A total of 71 male Sprague-Dawley rats underwent a 20% TBSA full-thickness scald. Wounds were inoculated with a solution containing 1 x 10 colony-forming units per milliliter of Pseudomonas aeruginosa 1244 (ATCC 27317). Treatments with 10% mafenide acetate cream (MAC), 5% MAS, 5% mafenide hydrochloride solution (MHS), and 4% chlorhexidine gluconate solution (CHG) were established. Agents were applied directly to the wound daily for 10 days. Animals were monitored for 21 days and euthanized if they manifested a moribund state as a result of sepsis. Survival to study completion in the negative control group (no treatment) was 25% (3/12). Survival in the positive control group (MAC) was 100%. None of the test agent groups demonstrated significant survival over the untreated controls; MAS resulted in 5/12 (42%) survival (P = .67), CHG in 4/12 (33%) survival (P = 1.0), and MHS resulted in 2/12 (17%) survival (P = 1.0). There were no significant differences in group weights on day 1. By day 6, all test agent groups were significantly underweight compared with the MAC group. This trend resolved as underweight animals died. We did not demonstrate significant prevention of wound sepsis with these agents as we used them. These techniques should not be substituted for established burn care. Aqueous direct topical antimicrobial agents have logistical advantages over creams and dressing soaks for field use, and the search for a battlefield-expedient agent for use at or near the point of wounding should continue. 相似文献

Flucloxacillin, fosfomycin, fusidic acid, teichomycin, and vancomycin were tested against 50 clinical isolates of methicillin-resistant Staphylococcus aureus by a broth macrodilution technique. Teichomycin had a narrow range of activity, similar to that of vancomycin (0.5 to 2.0 micrograms/ml). Fusidic acid had the lowest range of inhibitory activity, with 50 and 90% MICs of 0.19 and 0.35 micrograms/ml, respectively. Flucloxacillin and fosfomycin showed less activity, with MICs up to 32 micrograms/ml. 相似文献

In a previous study, the authors found persistent presence of acute inflammation markers such as C-reactive protein and complement factors locally in burn wounds. This persistence of acute inflammation may not only delay local burn wound healing but also have a systemic effect, for instance on the heart. Here, the effects of C1 esterase inhibitor (C1inh), an inhibitor of complement activation, on burn wound progression and the heart were analyzed in rats. Dorsal full-thickness burn wounds (2 × 4 cm) were induced on female Wistar rats (n = 14). The rats were divided into two groups (n = 7): a control group (just burns) and a C1inh group. C1inh was administered daily intravenously for 14 days. The burn wound, healthy skin from the hind leg (internal control), and the heart were then fixed in formalin. Tissues were analyzed for granulation tissue formation, reepithelialization, amount and type of infiltrating inflammatory cells (granulocytes and macrophages), and inflammatory markers (complement factors C3 and C4). C1inh treatment significantly reduced the amount of granulation tissue and significantly increased reepithelialization. C1inh also significantly reduced macrophage infiltration. Burns induced infiltration of macrophages into the ventricles of the heart and remarkably also into the atria of the heart. This effect could be counteracted by C1inh. These data show that systemic treatment with C1inh acts at different levels resulting in improved healing locally in burn wounds and systemically reduced inflammation in the heart. Therefore, C1inh might be a possible therapeutic intervention for burn wound patients. 相似文献
