- Vitiligo affects 1% of the world population and is a psychologically devastating disease especially when visible areas are affected, such as the face.
- Psoriasis is associated with the so-called named “metabolic syndrome” (MS): abdominal (central) obesity, elevated blood pressure, elevated fasting plasma glucose, high serum triglycerides, and low high-density cholesterol (HDL) levels)
- Metabolic syndrome is the result of insulin resistance
- This prospective case-control study from India included 35 patients with vitiligo aged 20 to 50 with at least 5% of body surface involvement were included. 30 healthy aged matched controls were included.
- Measurements of the following were done: fasting glucose, total cholesterol. triglycerides, HDL, and insulin levels.
- results show in a statistically significant way that:
- waist circumference (96cm vs 87cm) and Body Mass Index (25 vs 22) were significantly higher than controls
- hypertension was present in 40% of patients with vitiligo (vs 3.3% of controls)
- Serum triglycerides (142mg/dl vs 111) and insulin levels (7.8mg/dl vs 5.6) were raised.
- HDL was less than 50mg/dl in males and less than 40 in females
- There were no differences in plasma glucose and total cholesterol levels
- Although more studies are needed, this study suggests that monitoring lipid profiles, sugar levels and other signs of metabolic syndrome is warranted in patients with vitiligo.
