World Psoriasis Day


October 29 is World Psoriasis Day, promoted by IFPA (International Federation of Psoriasis Associates). Psoriasi

In this day, every year, a theme is chosen: for 2022 it is the mental health. Indeed, a quarter of people living with psoriatic disease experience depression. Talking about anxiety, the number rises to 48%.
In fact, very often cutaneous manifestations are object of fixed gazes, hesitations, abnormal attitudes and behaviors toward affected people.
Psoriasis is a chronic inflammatory disease of the skin characterized by hyperproliferation of keratinocytes with inflammation of the epidermis and dermis. The etiology is multifactorial: genetic predisposition, immune and environmental factors (stress, trauma, drugs, alcohol, abuse of nicotine). To date there is not cure.

Did you know that…

There is an association between psoriasis and hyperhomocysteinemia.

In fact, several studies show that in patients with psoriasis there are:

  • Higher homocysteine plasma levels than the control: probably for a reduction of folic acid and vitamin B12, which are involved in the homocysteine metabolism [1];
  • Direct proportionality between the severity of the disease and homocysteine plasma levels [2-5];
  • Alterations of the production of hydrogen sulfide (H2S) which is involved in dermatological diseases, including psoriasis [6]; H2S participates in various functions at the cutaneous level such as the control of itching or the reduction of neutrophils at the site of the lesion. In case of hyperhomocysteinemia, the activity of the enzymes involved in the production of cysteine is reduced and consequently the levels of H2S are lower [1].



Discover “ENDOMOX 600”, food supplement of Pizeta Pharma, containing many of the actors involved in homocysteine metabolism (Betaine, B12, B6, B2 Vitamins, folate as Quatrefolic®) and N-Acetil-L-cisteina, a sulphidric groups (-SH) donor, able to reduce plasma homocysteine.
