Background

Scalp seborrheic dermatitis is a chronic type of inflammatory dermatosis that is associated with sebum secretion and proliferation of Malassezia species. Ketoconazole or zinc-pyrithione shampoos are common treatments for scalp seborrheic dermatitis. However, shampoos comprising different compounds are required to provide patients with a wider range of treatment options.

Objective

This study was designed to evaluate a new-formula shampoo that contains natural ingredients-including extract of Rosa centifolia petals and epigallocatechin gallate (EGCG)-that exert antioxidative, anti-inflammatory, and sebum secretion inhibitory effects, and antifungal agents for the treatment of scalp seborrheic dermatitis.

Methods

Seventy-five patients were randomized into three treatment groups; new-formula shampoo, 2% ketoconazole shampoo, and 1% zinc- pyrithione shampoo. The clinical severity scores and sebum levels were assessed by the same dermatologists at baseline (week 0), and at 2 and 4 weeks after using the shampoo. User satisfaction and irritation were also assessed with the aid of a questionnaire.

Results

The efficacy of the new-formula shampoo was comparable to that of both the 1% zinc-pyrithione shampoo and the 2% ketoconazole shampoo. Furthermore, it was found to provide a more rapid response than the 1% zinc-pyrithione shampoo for mild erythema lesions and was associated with greater user satisfaction compared with the 2% ketoconazole shampoo. However, the new-formula shampoo did not exhibit the previously reported sebum inhibitory effect.

Conclusion

Extract of R. centifolia petals or EGCG could be useful ingredients in the treatment of scalp seborrheic dermatitis.  相似文献

Background Seborrheic dermatitis is a common inflammatory skin disorder. Yeasts of the genus Malassezia have been implicated in the etiology of seborrheic dermatitis, although this connection remains controversial. Ciclopirox is a synthetic, hydroxypyridone‐derived, broad‐spectrum antifungal agent with anti‐inflammatory properties. Methods A total of 499 US patients with seborrheic dermatitis of the scalp were randomized to apply either ciclopirox shampoo 1% or vehicle twice weekly for 4 weeks. The main efficacy parameters were based on 6‐point ordinal scales describing the disease's signs and symptoms (scaling, erythema and itching) and a 6‐point scale providing a global evaluation of the status of seborrheic dermatitis. Results Ciclopirox was significantly better than vehicle in effectively treating seborrheic dermatitis. ‘Effective treatment’ (score of 0 or 1 for disease status, scaling and erythema) was achieved in 26.0% of ciclopirox‐treated patients compared with 12.9% of vehicle‐treated patients (P = 0.0001; OR: 2.383, 95% CI: 1.494–3.799). The majority of subjects experienced adverse events that were mild in intensity, with skin and appendage reactions the most commonly reported, at similar frequency in both groups. Conclusions Ciclopirox shampoo 1% is effective and safe in the treatment of seborrheic dermatitis of the scalp.  相似文献

BACKGROUND: Recent studies of antidandruff shampoos or tonics containing antifungal or antibacterial agents produced effects suggestive of a potential hair growth benefit. OBJECTIVES: The purpose of this 6-month, 200-patient, randomized, investigator-blinded, parallel-group clinical study was to assess the hair growth benefits of a 1% pyrithione zinc shampoo. The efficacy of a 1% pyrithione zinc shampoo (used daily), was compared with that of a 5% minoxidil topical solution (applied twice daily), a placebo shampoo and a combination of the 1% pyrithione zinc shampoo and the 5% minoxidil topical solution. METHODS: Two hundred healthy men between the ages of 18 and 49 years (inclusive) exhibiting Hamilton-Norwood type III vertex or type IV baldness were enrolled. Total hair counts, the primary efficacy measure, were obtained using fibre-optic microscopy and a computer-assisted, manual hair count method. Secondary measures of efficacy included assessments of hair diameter, as well as patient and investigator global assessments of improvement in hair growth. These were based on photographs of the scalp using both midline and vertex views. RESULTS: Hair count results showed a significant (P < 0.05) net increase in total visible hair counts for the 1% pyrithione zinc shampoo, the 5% minoxidil topical solution, and the combination treatment groups relative to the placebo shampoo after 9 weeks of treatment. The relative increase in hair count for the 1% pyrithione zinc shampoo was slightly less than half that for the minoxidil topical solution and was essentially maintained throughout the 26-week treatment period. No advantage was seen in using both the 5% minoxidil topical solution and the 1% pyrithione zinc shampoo. A small increase in hair diameter was observed for the minoxidil-containing treatment groups at week 17. Assessments of global improvements by the patients and investigator generally showed the benefit of 5% minoxidil. The benefit of the 1% pyrithione zinc shampoo used alone tended (P < 0.1) to be apparent only to the investigator. CONCLUSIONS: Hair count results show a modest and sustained improvement in hair growth with daily use of a 1% pyrithione zinc shampoo over a 26-week treatment period.  相似文献

Ketoconazole (KET) and zinc pyrithione (ZPT) are compounds active against the Malassezia spp. yeasts, which are believed to play a major role in dandruff and seborrheic dermatitis. We compared the efficacy and safety of KET 2% and ZPT 1% in shampoo formulations for the alleviation of severe dandruff and seborrheic dermatitis. This open randomized, parallel-group trial began with a 2-week run-in phase during which subjects applied a neutral non-antidandruff shampoo. It was followed by a 4-week randomized treatment phase and a subsequent 4-week follow-up phase without treatment. Shampooing during the treatment period was carried out twice weekly for the KET group and at least twice weekly for the ZPT group in accordance with the label instructions. A total of 343 subjects were recruited to enter the trial. Of the 331 eligible volunteers, 171 were randomized to KET 2% and 160 to ZPT 1%. Clinical assessments were performed. Beneficial effects were evidenced for both medicated shampoos, but the effect was significantly better for KET 2%, which achieved a 73% improvement in the total dandruff severity score compared with 67% for ZPT 1% at week 4 (p < 0.02). The recurrence rate of the disease was also significantly lower following KET 2% treatment than following ZPT 1% treatment. As a consequence, the overall clearing of the skin condition at the end of treatment and follow-up phase was in favor of the KET 2% formulation (p = 0.004). Side effects were minimal. It is concluded that after a 4-week treatment, KET 2% shampoo was significantly superior to ZPT 1% shampoo in the treatment of subjects with severe dandruff or seborrheic dermatitis of the scalp. It is our assumption that this difference is noticeable for the patient and as a consequence relevant. Both formulations were well tolerated.  相似文献

Ciclopiroxolamine (CPO) and Zinc Pirythione (ZP) antifungals are efficient at treating scalp seborrheic dermatitis.This multicentre, single-blind, clinical study was conducted to evaluate the efficacy of a shampoo containing the 1.5% CPO/1% ZP association compared to the vehicle shampoo and to 2% ketoconazole foaming gel in the treatment of seborrheic dermatitis.In 189 patients randomised to apply 1 of the 3 products twice a week for 28 days, the global lesional score, erythema, pruritus, global efficacy, quality of life (SF12 and DLQI questionnaires) and tolerance were measured at 0, 7, 14 and 28 days.The 3 products reduced lesional score, erythema and pruritus from day 7 (p < 0.0001). The 2 antifungal treatments were significantly more efficient than the vehicle in reducing lesional score, erythema and pruritus at day 14 (p < 0.0001). At day 7, the CPO/ZP shampoo was more efficient in reducing pruritus than ketoconazole gel and vehicle (p = 0.032 and p < 0.001, respectively). The global efficacy of the 2 antifungal treatments assessed at day 28 by both investigator and patient was significantly better than that of the vehicle. Only the CPO/ZP shampoo improved all DLQI questionnaire dimensions.The CPO/ZP shampoo was as rapid and efficient as ketoconazole gel in SD treatment.  相似文献

Seventy patients with seborrhoeic dermatitis of the scalp, participated in a double-blind clinical trial using a tar/zinc pyrithione shampoo versus a placebo shampoo. Fifty-seven patients were evaluated after 6 weeks of treatment. Seventeen of twenty-seven using active shampoo and seven of thirty who used the placebo had no itching or scaling at the conclusion of the trial (P9 < O.01). No significant differences between the active and placebo shampoos were found for the parameters of erythema, seborrhoea and excoriations.  相似文献

Atopic dermatitis (AD) is a common, chronic, relapsing, severely pruritic, eczematous skin disease. Topical steroids are the mainstay of treatment. However, the adverse effects of steroids on hormonal function are the major obstacle for their use as long-term topical therapy. Intermittent dosing with potent topical steroids and/or combination therapy with steroid and tacrolimus have been frequently used in the daily management of AD to overcome the problems accompanying the long term use of steroids. We compared the clinical effects of topical steroid/tacrolimus and steroid/emollient combination treatments in 17 patients with AD. An intermittent topical betamethasone butyrate propionate/tacrolimus sequential therapy improved lichenification and chronic papules of patients with AD more efficiently than an intermittent topical betamethasone butyrate propionate/emollient sequential therapy after four weeks of treatment. Only one out of 17 patients complained of a mild, but temporary, burning sensation after tacrolimus application. The intermittent topical steroid/tacrolimus sequential therapy may be a useful adjunctive treatment for AD.  相似文献

Shampoo-induced allergic contact dermatitis is difficult to diagnose clinically because it can involve multiple and variable areas where the shampoo flows. Zinc pyrithione is a common active agent in medicated shampoo that is known to have good anti-dandruff and antifungal effects. Despite its low risk of sensitization, cases of allergic contact dermatitis still occur because of the popularity of such products. We report a 33-year-old man who developed pruritic rash on his scalp, face, neck, and hands after using a new shampoo containing zinc pyrithione. A patch test revealed a positive reaction to zinc pyrithione and personal shampoo containing zinc pyrithione.  相似文献

Background  Dandruff is a common scalp disorder affecting almost half of the post-pubertal population of any ethnicity and both genders. It is one of the major reasons for patients to consult a dermatologist and it is the cause of significant psychological and social distress.
Aims  The aim of this open study was to evaluate the benefit of a 4-week treatment with a shampoo containing 0.1% lipohydroxyacid (LHA) and 1.3% salicylic acid on the scalp condition and on the quality of life of 275 volunteers with seborrheic dermatitis (SD) ( n  = 226) or light-to-moderate scalp psoriasis (SP) ( n  = 49).
Methods  The clinical benefit of the treatment was assessed by scoring the following parameters, i.e., severity of the dermatosis, scaling, itching, excoriations, and superficial burning sensation. The impact on the quality of life was assessed using the Scalpdex, a questionnaire specially developed by Chen et al. for patients with scalp dermatitis, which includes 23 questions regarding the symptoms, functioning and emotions affected by scalp dermatosis.
Results  The shampoo used in this study was well tolerated. After a 4-week treatment, dermatologists noticed a significant clinical improvement of all the scalp parameters evaluated (i.e., the composite lesional score was improved in 91% and 77% of the patients with SD or SP respectively). The symptoms, functioning and emotions scores of quality of life were also significantly improved in relation to the improvement of scalp condition.
Conclusion  This study not only allowed a better understanding of the SD and SP patient's profile but also demonstrated that the shampoo evaluated is a convenient, efficient, safe, and well-tolerated cosmetic treatment of SD and light-to-moderate SP improving greatly the quality of life of the treated patients.  相似文献

Pityriasis (tinea) versicolor and seborrheic dermatitis are two very common skin diseases. Pityriasis versicolor is a chronic superficial fungal disease usually located on the upper trunk, neck, or upper arms. In pityriasis versicolor, the lipophilic yeast Malassezia (also know as Pityrosporum ovale or P. orbiculare) changes from the blastospore form to the mycelial form under the influence of predisposing factors. The most important exogenous factors are high temperatures and a high relative humidity which probably explain why pityriasis versicolor is more common in the tropics. The most important endogenous factors are greasy skin, hyperhidrosis, hereditary factors, corticosteroid treatment and immunodeficiency. There are many ways of treating pityriasis versicolor topically. Options include propylene glycol, ketoconazole shampoo, zinc pyrithione shampoo, ciclopiroxamine, selenium sulfide, and topical antifungals. In difficult cases, short term treatment with fluconazole or itraconazole is effective and well tolerated. To avoid recurrence a prophylactic treatment regimen is mandatory. Seborrheic dermatitis is characterized by red scaly lesions predominantly located on the scalp, face and upper trunk. There are now many studies indicating that Malassezia plays an important role in this condition. Even a normal number of Malassezia will start an inflammatory reaction. Mild corticosteroids are effective in the treatment of seborrheic dermatitis. However, the disease recurs quickly, often within just a few days. Antifungal therapy is effective in the treatment of seborrheic dermatitis and, because it reduces the number of Malassezia, the time to recurrence is increased compared with treatment with corticosteroids. Antifungal therapy should be the primary treatment of this disease.  相似文献

A case of allergic contact dermatitis to a shampoo containing zinc pyrithione associated with an eruption of pustular psoriasis is reported. The patient had had stable psoriasis for 5 years, and never any other skin disease. Within 1 week, she developed severe generalized pustular psoriasis with many lesions where the shampoo was applied. Treatment with cyclosporin, 200 to 300 mg daily, cleared the eruption within 4 weeks, except for psoriasis of the scalp. Extensive patch testing revealed a relevant sensitization to zinc pyrithione. This case illustrates that a generalized pustular psoriasis can be provoked by a substance present in a hair shampoo. Short-term treatment with cyclosporin is valuable in exacerbations of psoriasis caused by allergic contact dermatitis.  相似文献

Background

Seborrheic dermatitis is a common chronic inflammatory skin disorder that affects the scalp and is characterized by erythema and oily scales. It could perhaps be difficult to control and could seriously degrade one's quality of life. The study's objective is to assess the effectiveness of intradermal administrations of QR678 Neo® hair growth factor therapy for the treatment of scalp seborrheic dermatitis in both men and women.

Method

Forty male and female patients with clinically diagnosed seborrheic dermatitis of the scalp in the age 18–45 years, not satisfactorily responding to standard therapy for at least 6 months, were included. 1 mL solution of QR678 Neo® was administered in the scalp skin of all patients at 3-week interval till eight sessions. Patients were advised to continue with antifungal shampoo and topical antifungal solution with steroid combination which they had been on during the treatment. Assessment of disease severity, dermoscopic evaluation, and self-assessment were done at baseline and at the end of the fourth and the eighth sessions.

Results

Improvement was observed in adherent scalp flaking score after eighth session (mean = 12) compared to baseline (mean = 60). The dermoscopic evaluation showed a noticeable difference from baseline (mean = 11) in erythema and scaling with the Seborrheic Dermatitis Scalp Severity Index tool at the end of treatment (mean = 2). A high satisfaction score was given for the efficiency in the self-assessment questionnaire.

Conclusion

Our study proved that treatment with QR678 Neo® led to an improvement in the overall scalp condition by the resolution of flaking and inflammation.  相似文献

Zinc pyrithione is a shampoo ingredient that has been shown to be safe and effective for dandruff and scalp psoriasis. It is thought to decrease the cell turnover rate in hyperproliferative dermatoses such as psoriasis, and also has fungistatic and antimicrobial activity, although its exact mode of action is unknown. In psoriasis, external factors, such as trauma, infection and drugs, may provoke aggravated manifestations of psoriatic skin lesions. Rarely, irritant or allergic mechanisms are likely causes of psoriatic flare and Kobnerization. A patient had had stable psoriasis for 25 years and no any other skin disease. Within 20 days, she developed an aggravated scaly erythematous patch on the scalp, where a shampoo had been applied, and simultaneously developed pustular psoriasis on both forearms. Patch testing showed a relevant sensitization to zinc pyrithione, and we observed symptomatic aggravation by provocation testing with zinc pyrithione shampoo. We report a rare case of psoriasis aggravated by the induction of allergic contact dermatitis from zinc pyrithione after using antidandruff shampoo.  相似文献

OBJECTIVE: To demonstrate the efficacy, safety, and tolerance of ciclopirox shampoo for treatment and prophylaxis of seborrheic dermatitis of the scalp. DESIGN: Multicenter, randomized, double-blind, vehicle-controlled study. After treatment with ciclopirox shampoo once or twice weekly or vehicle for 4 weeks (study segment A), responders were randomized to a 12-week prophylactic study arm (segment B). SETTING: Forty-five medical centers in Germany (n = 19), France (n = 15), the United Kingdom (n = 8), and Austria (n = 3).Patients A total of 1000 patients with stable or exacerbating seborrheic dermatitis of the scalp.Interventions A total of 949 patients were randomized to receive ciclopirox treatment once or twice weekly or vehicle for 4 weeks. Thereafter, 428 responders received either ciclopirox prophylaxis once weekly or every 2 weeks or vehicle for 3 months. MAIN OUTCOME MEASURES: Primary and secondary: response of "effectively treated" and "cured," with investigators and patients rating acceptability and tolerance. RESULTS: Ciclopirox twice and once weekly produced response rates of 57.9% and 45.4%, respectively, compared with 31.6% for vehicle. Relapses occurred in 14.7% of patients using prophylactic ciclopirox once weekly, 22.1% of those in the prophylactic group shampooing once every 2 weeks, and 35.5% in the vehicle group. The few adverse events were evenly distributed among groups. Local tolerance and cosmetic acceptability were "good" in more than 85% of subjects. CONCLUSIONS: Seborrheic dermatitis of the scalp responds well to 1% ciclopirox shampoo once or twice weekly for 4 weeks. A low relapse rate is maintained by once-weekly shampooing or shampooing once every 2 weeks. These treatments are safe and well-tolerated.  相似文献

IntroductionThe clinical characteristics of seborrheic dermatitis (SD), therapeutic strategies employed in current clinical practice and impact on the quality of life in the Spanish population are described.MethodsAn epidemiological, multicenter, transversal study in patients older than 16 years with seborrheic dermatitis. We evaluated the intensity of symptoms (scale 0-4), and impact on the quality of life by the Skindex-29 questionnaire (scale 0-100).ResultsTwo thousand one hundred and fifty nine patients participated, the mean age was 43,6 years, 55% were men and 42 % had a family history of seborrheic dermatitis. Diagnosis is usually carried out at a mean age of 33,7 years. The median number of outbreaks in the last year is three. The median duration of each outbreak is 14 days. The most involved areas are the face (88%) and scalp (70%). The mean intensities are as follows: scaling 1.9, erythema 1.89, pruritus 1.73, oily skin 1.52, and induration 0.87. Ninety-eight percent of patients report a trigger factor for outbreaks, namely stress/depression/fatigue (76%) and seasonal variation (44%). Acne is the most common concomitant disease (35%). The most common treatments are topical steroids (60%), imidazole antifungals (35%) and hydratating/nutritive products (31%). The mean Skindex-29 global score is 20.5.ConclusionsThe most common clinical profile of seborrheic dermatitis is a 40-year-old patient with facial/scalp involvement of mild to moderate intensity with a history of stress/depression/fatigue prior to the outbreak. The most common treatments in the daily clinical practice are topical steroids and imidazole antifungals. The impact of seborrheic dermatitis in the quality of life is low.  相似文献

Vitiligo is a common acquired idiopathic hypomelanotic disorder characterized by circumscribed depigmented maculae. The conventional treatments are limited by their inconsistent and incomplete responses, relapse rate, inconvenience to apply, side-effects and especially long-term effects. The aim of the present study was to determine the efficacy and safety of topical tacrolimus as monotherapy for the treatment of face/neck vitiligo in Taiwan. This was a multicenter, open-label, non-comparative study. Patients were at least 16 years old and had vitiligo lesions with Vitiligo Index of Disease Activity score +1 or more on face or neck. Patients received a monotherapy with 0.1% of tacrolimus ointment twice daily for 12 weeks. The efficacy was measured by the percentage of repigmentation of target lesion, which was graded as minimal (1–25%), mild (26–50%), moderate (51–75%) or excellent (76–100%). Patients who had at least mild repigmentation were defined as responders. A total of 61 patients were enrolled in this investigation. Most of the patients showed repigmentation at week 4. At the end of treatment, all patients showed repigmentation and 45.9% of patients were responders. During the study, 15 adverse events related to the ointment were reported. All the reported adverse events were mild and similar to the well-known adverse effect of tacrolimus in the treatment of atopic dermatitis. Tacrolimus ointment is effective and well tolerated for the treatment of patients with vitiligo in Taiwan. It will be another drug of choice for persons with vitiligo who are unable to receive regular phototherapy and fear the side-effects of topical steroid in long-term use.  相似文献

Background Improper long‐term, even low‐dose, topical corticosteroids, especially application to the face, could induce steroid dermatitis, which was refractory and detrimental to the quality of life. Objective To evaluate the quality of life in patients with facial steroid dermatitis before and after the treatment of doxycycline and indomethacin plus support therapy. Study design A prospective study. Setting Outpatients of the Department of dermatology, the Third Hospital of Hangzhou, from August 2, 2004, to April 20, 2005. Subjects Fifty consecutive outpatients completed the treatment. Intervention The intervention is doxycycline 10 mg twice a day and indomethacin 25 mg twice a day for 4 weeks, cetirizine or loratadine 10 mg daily if pruritic, topical white petroleum if feeling dry and wet dressing if burning and oedema, plus psychological support and health education. Main outcome measure The efficacy of the treatment was quantified using a 24‐point steroid clinical score. The detriment of the quality of life was quantified using a 30‐point Dermatology Life Quality Index. Results The steroid dermatitis clinical score decreased significantly from 15.06 ± 4.61 at baseline to 4.52 ± 3.39 at 2 weeks after the end of treatment (week 6; P < 0.001). Twenty‐one patients underwent a rebound phenomenon and the steroid dermatitis clinical score increased significantly from 13.71 ± 4.33 at baseline (week 0) to 19.24 ± 3.40 at 1 week after treatment (week 1; P < 0.001). Quality of life score decreased significantly from 13.76 ± 7.68 at baseline to 3.44 ± 2.57 at 2 weeks after the end of treatment (week 6; P < 0.001). Conclusions The quality of life was profoundly affected by facial steroid dermatitis. Doxycycline and indomethacin plus support therapy might be effective in patients with facial steroid dermatitis.  相似文献
