Assessment and Comparison of Quality of Life in Patients with Melasma and Vitiligo.

Background Melasma is an acquired hyperpigmentary condition that is characterized by development of irregular brown to black macules occurring predominantly on the face. Vitiligo is an acquired depigmenting skin disease characterized by progressive loss of inherited skin colour, which leads to appearance of white patches. Both the conditions occur more frequently in people with racially pigmented skin resulting in psychological morbidities and impacting the quality of life. Objective To evaluate and compare the quality of life in patients suffering from melasma or vitiligo, which represent two opposite ends of pigmentary disorders using the Dermatology Life Quality Index (DLQI). Method This was a hospital based cross sectional study that was conducted at the Department of Dermatology and Venereology, Tribhuwan University Teaching Hospital from September 2016 to August 2017. The study population included adult patients of either sex with melasma or vitiligo, who consented to participate in the study. Result There were a total of 100 patients each in both melasma and vitiligo groups. While females outnumbered their male counterparts by a ratio of 9:1 in melasma, the gender distribution was more equal in vitiligo. Melasma had a mean DLQI score of 5.64 ± 5.41 and a median score of 4 while vitiligo had a mean DLQI score of 4.13 ± 3.74 and a median score of 3. Conclusion Melasma patients had a higher impairment in quality of life compared to vitiligo patients. The quality of life in both the conditions varied based on age, gender, duration and distribution.
