Randomized controlled trial of topical mupirocin versus mupirocin with sucralfate combination in chronic skin ulcers

Comparison of topical sucralfate with dexpanthenol in rat wound model

Wound healing is a dynamic process initiated in response to injury. There are many factors that have detrimental effects on the wound healing process. Numerous studies have been conducted for improving wound healing processes. Dexpanthenol is widely used to accelerate wound healing. Sucralfate is used for the treatment of peptic ulcers. We aimed to compare the efficacy of topical Dexpanthenol and Sucralfate in an experimental wound model in rats via histopathological examinations and immune histochemical determinations, as well, to evaluate their effects on EGF levels. Three different groups were formed: the Control Group, the Dexpanthenol Group and the Sucralfate Group. Full-thickness skin wounds were created on the back of each rat and isotonic saline was applied to the wounds of the rats in the control group, Bepanthol^® cream was applied in Dexpanthenol Group and 10% Sucralfate cream was applied in Sucralfate Group, once a day. On the 7th, 14th and 21st days the wounds were measured and seven rats from each group were sacrificed and the wounds were excised for histopathological examination. Sucralfate increased wound healing rates by increasing neovascularization, fibroblast activation, reepithelialization and collagen density, as well as dexpanthenol. Our study revealed that the dexpanthenol and sucralfate groups were better than the control group in terms of their effects on wound healing, however there was no statistically significant difference among these two groups. Sucralfate improves EGF expression in skin wounds and has positive results on skin wound healing comparable to dexpanthenol.

Topical sucralfate for treatment of mucocutaneous conditions: A systematic review on clinical evidence

Sucralfate is an aluminum salt of sucrose octasulfate, generally considered safe in terms of adverse effects. Systemic sucralfate is FDA-approved for the treatment of duodenal ulcers. Since 1991, topical sucralfate has been used in various mucocutaneous conditions, but it is not approved by the FDA yet. In this systematic review, the online databases were searched with appropriate keywords, and the papers were screened by the authors. After screening steps, the relevant articles were selected according to the inclusions and exclusions criteria. Finally, the full texts of 18 articles were included for final evaluations. In conclusion, topical sucralfate has some clinical benefit in several mucocutaneous conditions, including mucocutaneous inflammatory conditions (e.g., post-radiotherapy reaction, diaper dermatitis, keratoconjunctivitis sicca, etc.), mucocutaneous infectious disorders (e.g., peristomal wound reaction / Infection); ulcers; burns, and also pain relief.

Sucralfate enemas reduce the oxidative tissue damage and preserves the contents of E-cadherin and ?-catenin in colonic mucosa without fecal stream

PURPOSE

To evaluate the effects of sucralfate enemas in tissue contents of E-cadherin and ?-catenin in an experimental diversion colitis.

METHODS

Thirty-six male Wistar rats were submitted to a proximal colostomy and a distal mucous fistula. They were allocated into three groups: first group received daily saline enemas (2 mL/day) and the two other groups daily enemas with sucralfate at dosage of 1 or 2 g/kg/day, respectively. Six animals of each group were euthanized after two weeks and six animals after four weeks. The inflammation of the excluded mucosa was evaluated by histological analysis. The oxidative damage was quantified by measurement of malondialdehyde tissue levels. The expression of E-cadherin and ?-catenin was identified by immunohistochemistry, and its contents were quantified by computer-assisted image analysis.

RESULTS

Sucralfate enemas reduced inflammation in animals subjected to treatment with 2 g/kg/day by four weeks, and the levels of oxidative damage in mucosa without fecal stream irrespective of concentration and time of intervention. E-cadherin and ?-catenin content increased in segments without fecal stream in those animals subjected to treatment with sucralfate.

CONCLUSIONS

Sucralfate reduces the inflammation and oxidative stress and increases the tissue content of E-cadherin and ?-catenin in colonic mucosa devoid to the fecal stream.
