Summary

The objective of the study was to compare the level of serum FT4 and TSH in patients with mild melasma and moderate-severe melasma. The determination of melasma lesion could also be known by using Janus II facial analysis UV light and polarization light to analyze the pattern of hyperpigmentation on melasma. This was a descriptive-analytic study used a cross-sectional method that was performed in 2019 at two different dermatology and venerology clinics in Indonesia, Cipto Mangunkusumo Hospital Jakarta and Gatot Subroto Army Hospital Jakarta. Forty-eight subjects with melasma, 50% diagnosed with mild melasma and 50% with moderate-severe melasma according to the modified melasma area and severity index (mMASI) score. The level of serum FT4 and TSH were then measured in both groups of the patients.

Detailed description

Melasma has been suspected to be linked with thyroid hormone. There is no study that explains the association of thyroid hormone level with melasma severity. This study aims to find the difference in the levels of thyroid hormone in varying severity of melasma. This was a descriptive-analytic study used a cross-sectional method that was performed in 2019 at two different dermatology and venerology clinics in Indonesia, Cipto Mangunkusumo Hospital Jakarta and Gatot Subroto Army Hospital Jakarta. Forty eight patients participated in this study, 50% diagnosed with mild melasma and 50% with moderate-severe melasma. Subjects are chosen consecutively based on mMASI and Janus II measurement. The level of serum FT4 and TSH were then measured in both groups of the patients. The data is tabulated and a comparative analysis of serum FT4 and TSH levels with mild and moderate-severe melasma is done. In addition, this study also analyzes the level of serum FT4 and TSH with the result of Janus II facial analysis system scoring. The same method of analysis was done to know the association between mMASI and examination by using Janus II facial analysis system. This study aims to find the difference in the levels of thyroid hormone in varying severity of melasma.
