Efficacy of topical calcineurin inhibitors in psoriasis

BACKGROUND

Topical calcineurin inhibitors (tacrolimus and pimecrolimus) are indicated for the treatment of atopic dermatitis but have also been studied in the treatment of psoriasis.

OBJECTIVE

To define the efficacy of topical calcineurin inhibitors in the treatment of psoriasis.

METHODS

We searched for English-language articles published since 1990 in PubMed, Ovid/Cochrane, and Embase using "tacrolimus," "pimecrolimus," or "topical calcineurin inhibitors" and "psoriasis."

RESULTS

Nine double-blind and 13 open studies demonstrated the efficacy of topical tacrolimus in psoriasis, especially for facial, genital, and intertrigious psoriasis, and four double-blind and one open study demonstrated the efficacy of topical pimecrolimus.

CONCLUSIONS

The evidence (double-blind and open studies) is strong that topical tacrolimus and, to a lesser extent, pimecrolimus have efficacy in the treatment of psoriasis. Since these agents do not cause cutaneous atrophy, they likely have a special role in facial, genital, and intertriginous psoriasis. Further studies would help define their roles in psoriasis.

Pimecrolimus, yet another intriguing topical immunomodulator

Pimecrolimus, yet another intriguing local immunomodulator, has been approved for use in atopic dermatitis in individuals of more then 2 years of age. However, its indications are now being extended to include a variety of inflammatory dermatoses, which are identified in the current article with a proviso that their use should be considered only as an alternative when conventional modalities have failed.

Management of childhood psoriasis

Treating children with psoriasis represents one of the most rewarding yet constantly challenging endeavors in dermatology. These patients require time, energy, enthusiasm, empathy, and current, comprehensive knowledge of the unique clinical presentations in children and available therapies, including clinical action spectrum, mechanism of action, potential toxicity, and monitoring. Longitudinal trials examining the epidemiology and natural history of psoriasis, as well as the safety and efficacy of current and emerging treatments, are desperately needed in the pediatric population. Partner with the patient, family, and other multidisciplinary providers to form an educational and therapeutic alliance. Early in the course of disease, schedule frequent visits for reinforcement of the therapeutic plan, education, clinical and treatment monitoring, and support. As the disease and the patient's physical, psychosocial and emotional level of functioning evolve, so too will the requirement for follow-up and monitoring. Patient advocacy and education groups, such as the National Psoriasis Foundation (www.psoriasis.org; 800-723-9166) are excellent resources and can serve as an extension of your comprehensive care.

Use of pimecrolimus cream in disorders other than atopic dermatitis

BACKGROUND

Pimecrolimus is indicated for treatment of atopic dermatitis and has been evaluated in many other disorders.

OBJECTIVE

To review the efficacy of pimecrolimus in treatment of disorders other than atopic dermatitis.

METHODS

We performed a PubMed search of the English-language literature using the key word "pimecrolimus." We reviewed articles reporting the use of pimecrolimus in disorders other than atopic dermatitis and classified them by the type of study used to evaluate efficacy.

RESULTS

Randomized, double-blind studies have shown that pimecrolimus is superior to vehicle in treatment of seborrheic dermatitis, hand dermatitis, and asteatotic eczema but have yielded conflicting results regarding intertriginous psoriasis and vitiligo. Open-label studies involving four or more patients have shown favorable results in many disorders, including contact dermatitis, rosacea, lichen sclerosus, and oral and genital lichen planus. Case reports have shown that topical pimecrolimus may be useful in cutaneous graft-versus-host disease, lichen striatus, cutaneous lichen planus, and many other disorders.

CONCLUSIONS

Topical pimecrolimus appears to be an effective treatment for many disorders other than atopic dermatitis, especially seborrheic dermatitis, hand dermatitis, and asteatoic eczema. It may be effective in many other disorders, but its role in these disorders remains to be clarified by additional studies.
