Validation of a melasma quality of life questionnaire for Brazilian Portuguese language: the MelasQoL-BP study and improvement of QoL of melasma patients after triple combination therapy
Background Pigmentation disorders, such as melasma, greatly influence the quality of life (QoL) of affected individuals who usually consider the disorder to be more severe than the objective clinical scores. Several instruments have been successfully developed to evaluate QoL. However, they must be adapted to the target population in terms of language and cultural diversity. the first, specific QoL questionnaire for melasma (MelasQoL) was developed for English speaking patients.Objectives To validate the Brazilian Portuguese version of the MelasQoL evaluation questionnaire for patients with melasma (MelasQoL-BP) and to assess the impact of treatment with a triple combination cream (hydroquinone, fluocinolone acetonide and tretinoin) on the QoL of patients with moderate-to-severe melasma.Methods and Results Three hundred individuals from the five Brazilian geographic regions took part in this multicentre study. Their mean age was 42 years and skin phototype distribution was: type II 7.0% of patients, III 23.7%, IV 42.7% and V 22.7%. Melasma Area and Severity Index (MASI), MelasQoL-BP and the short version of the QoL assessment instrument from the World Health Organization (WHOQOL-BREF) were used to assess melasma severity and QoL at baseline. MelasQoL-BP was previously translated and culturally adapted from the English version, with participation of the authors and according to the standards of the World Health Organization (WHO). From the original sample, we randomized150 volunteers to treat melasma and repeated the evaluation after 8 weeks. the analysis of the MelasQoL-BP baseline answers demonstrated an important impact of the disease on skin appearance (65% of patients were bothered all the time or most of the time), frustration (55%), embarrassment (57%) and influence of the disease on interpersonal relationships (42%). Forty-three per cent of patients felt not attractive or even dirty due to their skin condition. MelasQoL-BP results showed significant internal consistency (Cronbach's alpha coefficient 0.919; P < 0.001) and good correlation with MASI scores. After treatment, the global assessment showed good or excellent results in 91.4% of the patients. the clinical outcome was not associated with the initial MASI score (P = 0.814; chi-square), skin colour (P = 0.449; probability ratio) or skin pigmentation (P = 0.814; chi-square). There was also a significant reduction on MelasQoL-BP scores (Wilcoxon test; P < 0.001) after treatment, with the mean +/- SD results shifting from 44.4 +/- 14.9 at baseline to 24.3 +/- 15.5 after treatment. the analysis of the MelasQoL-BP before and after treatment showed an important effect of the impact of treatment on a number of QoL measures. of note, skin appearance (69.8 vs. 10.1% of patients were bothered all the time or most of the time, respectively), frustration (59.7% vs. 12.2%, respectively), embarrassment (56% vs. 9.3%, respectively) and influence of the disease on interpersonal relationships (35.3% vs. 5.8%, respectively) were greatly improved.Conclusion This study demonstrates that MelasQoL-BP is a valid instrument and can be used to evaluate the quality of life and response to melasma treatment in Brazilian patients. the triple combination treatment produced significant results, regarding both clinical severity and quality of life.Univ Fed Rio Grande Sul, Hosp Clin, Dept Dermatol, Porto Alegre, RS, BrazilDermatol Clin Doris Hexsel, Porto Alegre, RS, BrazilMaria de Lourdes Viegas Dermatol Clin, Rio de Janeiro, BrazilSanta Casa Misericordia Rio de Janeiro, Dermatol Ctr, Rio de Janeiro, BrazilUniversidade Federal de São Paulo, Cosmiatry & Surg Div, São Paulo, BrazilHosp Servidor Publ Municipal São Paulo, São Paulo, BrazilHosp Univ Prof Edgar Santos, Salvador, BA, BrazilUniv Para State, Dept Dermatol, Belem, Para, BrazilFed Univ Ceara, Hosp Univ Walter Cantidio, Fortaleza, Ceara, BrazilUniv Goias, Dept Dermatol, Goiania, Go, BrazilUniversidade Federal de São Paulo, Cosmiatry & Surg Div, São Paulo, BrazilWeb of Scienc

Preventing melasma recurrence: prescribing a maintenance regimen with an effective triple combination cream based on long-standing clinical severity
Background the relapsing nature of melasma emphasizes the need to maintain efficacy achieved after acute treatment.Objective To compare clinical efficacy and safety of two 6-month Triple Combination (TC; containing fluocinolone acetonide, hydroquinone and tretinoin) maintenance regimens in subjects with moderate to severe melasma, after daily treatment up to 8 weeks.Methods This randomized, investigator-blinded, controlled study had a maintenance phase of 6 months. Sixteen centres in Brazil and Mexico enrolled 242 subjects 18 years or older attaining no or mild melasma after 8 weeks of daily TC applications. Subjects were randomized to receive TC in a twice weekly or tapering regimen [3/week (1st month), 2/week (2nd month), 1/week (4th month)].Efficacy and safety measurements included median time to relapse and relapse-free rate, Global Severity Score, Melasma Area and Severity Index score (MASI), subject's assessment, quality of life questionnaire (MelasQol), and adverse events.Results the majority (78.8%) had no or mild melasma (GSS <= 1) at week 8 and entered maintenance phase. After 6 months, 53% of patients remained relapse-free with improved quality of life, and time to relapse was similar between groups (about 190 days). Melasma severity at study entry, not maintenance baseline, influenced relapse rate. the twice weekly regimen tended to show better effectiveness in postponing relapse in severe melasma. Both regimens were safe.Conclusions After resolution of melasma with TC, maintenance therapy over 6 months was successful in preventing relapse in over half of the patients who entered maintenance phase. Prescribing medicines should be adapted to patients based on melasma severity.Hosp Gen Mexico OPD, Mexico City, DF, MexicoUniv Rio Grande Sul, Hosp Clin Porto Alegre, Porto Alegre, RS, BrazilHosp Univ Jose E Gonzalez, Monterrey, MexicoInst Dermatol & Estet Rio de Janeiro, Rio de Janeiro, BrazilHosp Univ Onofre Lopes, Petropolis, BrazilHosp Clin FMUSP, São Paulo, BrazilHosp Servidor Publ Estado São Paulo, São Paulo, BrazilHosp Servidor Publ Municipal São Paulo, São Paulo, BrazilUniv Fed Bahia, BR-41170290 Salvador, BA, BrazilUniversidade Federal de São Paulo, São Paulo, BrazilUniversidade Federal de São Paulo, EPM, São Paulo, BrazilWeb of Scienc
