Definitions
- Vitiligo is neither contagious nor painful but it can cause significant psychological distress. Note that people with dark skin particularly suffer from it because this condition is even more visible in them. However, the impact on quality of life is significant for all affected people. Vitiligo is still insufficiently treated by doctors.
- the disease progresses at an unpredictable pace and can stop or spread continuously or most often in flare-ups. Vitiligo can thus progress in phases, with worsening sometimes occurring after a psychological or physical triggering event. In very rare cases, the plaques disappear on their own. These people also have a greater likelihood of suffering from other autoimmune diseases, including autoimmune dysthyroidism.
- the subject it is a mammal and, preferably, a human.
- lysate we mean a culture of such a bacterial strain which has been subjected to cell lysis.
