Composition for use in the treatment of Psoriasis

The present invention relates to a composition for use in the treatment of Psoriasis.

Psoriasis is linked to chronic inflammation of the skin and occurs in people who are genetically predisposed, usually due to an additional physical or psychological factor. In other words and more specifically, Psoriasis is a common chronic erythematosquamous dermatosis. This pathology is characterized by a disorder of epidermal homeostasis (hyperproliferation and disorders of keratinocyte differentiation) as well as by complex dermo-epidermal inflammatory phenomena responsible for an accelerated renewal of the epidermis induced by extrakeratinocyte proliferation factors or by intrinsic keratinocyte abnormalities.

Extrakeratinocyte factors could be produced by neutrophils (which migrate in the stratum corneum and participate in the histological signs of Psoriasis) or by CD4 lymphocytes which, after activation by classical antigens or activated superantigens, would produce various cytokines stimulating turnover turnover. keratinocytes.

Regarding intrakeratinocyte factors, various anomalies of transduction from the membrane to the nucleus have been described in Psoriasis (protein kinase A, C pathway, cyclic nucleotides, ...). There is an increase in the expression of different receptors to EGF (Epidermal Growth Factor), various anomalies in the adhesion molecules, a disturbance of various growth factors and differentiation of keratinocytes (TGF alpha, IL-6,. ..) and various anomalies in the genes involved in the response to vitamin D and vitamin A which participate in proliferation and epidermal differentiation.

In addition to extrakeratinocyte and intrakeratinocyte factors, etiological factors are also put forward for Psoriasis, such as environmental factors, genetic predispositions, infectious factors, taking certain drugs, psychological factors and aggravating factors such as tobacco and alcohol.

The diagnosis of Psoriasis is primarily clinical and is based on the observation of elementary lesions in the form of well-defined erythematous-scaly spots, rounded, oval or polycyclic. Generally, Psoriasis is localized in areas exposed to friction (elbows, knees, legs, lumbo-sacral region, scalp and nails). There are several clinical forms of Psoriasis, including scalp psoriasis, nail psoriasis, erythrodermic psoriasis, arthropathic psoriasis, pustular psoriasis or even psoriasis in children.

The evolution of Psoriasis is a chronic dermatosis and occurs by relapses interspersed with periods of remission of varying durations during which the lesions are generally minimal. These remissions are more frequent in summer due to the effect of ultraviolet rays. Flares, often unpredictable, are also sometimes triggered by psychological factors, stress, drugs, ENT infections or even a skin attack.

Note that Psoriasis is a frequent disease since it affects around 3 to 5% of the European population, this at all ages. If it is mostly a mild illness, Psoriasis can be disabling, especially for aesthetic reasons. As indicated above, Psoriasis is due to chronic inflammation of the skin, the precise origin of which, however, is not yet known. This inflammation leads to a significant proliferation of cells in the epidermis, the keratinocytes which, instead of being renewed in 28 days, are renewed in 3 days. This accelerated renewal of the epidermis is accompanied by an abnormality of the cells which do not have time to properly finalize their normal maturation.

If the causes of an onset / remission of Psoriasis are not well determined to date, it is generally accepted that it is a multifactorial pathology and that at least the following factors are involved: inflammation , oxidation (oxidative stress) and the immune system. In addition, Psoriasis has a wide variety of phenotypes due to a complex and varied multifactorial combination of immunological mechanisms, a polygenic profile and cellular abnormalities in the skin.

Among the treatments for Psoriasis, a distinction is made between local treatments which are based on the use of dermocorticoids, analogs of vitamin D3 or on a combination of these two products. Dermocorticoids are generally used as an ointment or cream. However, these treatments are responsible for numerous and non-negligible side effects, which is why it is recommended to perform these treatments for a limited time and to closely monitor the amounts used. In addition, vitamin D analogs like calcipotriol (Daivonex), tacalcitol (Apsor) and calcitriol (Silkis) exhibit slower activity than dermocorticoids and may be responsible for skin irritations (in the face and in the folds of the skin).

Other topical treatments also exist such as baths and emollients used to strip lesions and relieve pruritus. Salicylic acid is also used (in a fatty excipient) to scour very scaly lesions but this is contraindicated in children (risk of salicylated poisoning). Tazarotene (Zorac), a topical retinoid, is also used but an irritant effect can be observed and it is contraindicated in case of pregnancy.

Various phototherapies are also used to treat Psoriasis: PUVA therapy and UVB narrow spectrum phototherapy (TL-01) at the rate of 3 sessions per week, which makes this therapy restrictive.

If the treatments mentioned above prove to be ineffective, more general treatments are then applied and are carried out essentially by the oral intake of drugs of which there are four families:

- your retinoids (derivatives of vitamin A synthesis) which are formally contraindicated in young women without effective contraception due to the risk of serious malformations in the fetus;

- methotrexate preventing the multiplication of cells. Regular monitoring of liver enzymes and white blood cells by blood test is necessary as well as a chest x-ray before starting treatment;

- ciclosporin, an immunosuppressant whose administration cannot be considered beyond a year or two at the most, because of the risks of renal damage. Its prescription requires monitoring of blood pressure and renal function; and

- your biotherapies reserved for severe forms that have not responded or that have a contraindication to at least two other prior treatments including phototherapy, methotrexate and ciclosporin.

These are treatments which require a certain number of examinations to be carried out before they are started, in particular an X-ray of the lungs and an intradermal reaction to tuberculin to eliminate the existence of latent tuberculosis, as well than a blood test to rule out kidney failure and / or liver failure.

Biotherapies are more specifically anti-TNF or T-lymphocyte aimed by inhibiting the LFA1-ICAM1 link.

In practice, it appears that current treatments are responsible for side effects such as dry skin and mucosa, scaling, hair loss, liver or lung fibrosis, nephrotoxicity or even high blood pressure. More particularly, with regard to general treatments, it is advisable to resort to them exceptionally and to monitor them scrupulously in view of significant side effects.

All the treatments mentioned above (local and general) therefore have certain limits on the one hand because of the significant side effects observed but also on the other hand because they do not intervene in a global manner on the three main causes recognized Psoriasis, that is to say on inflammation, on oxidative stress and on the immune system.

To date, there is therefore unfortunately no drug treatment proposing a composition intervening in a global and simultaneous manner on your three main recognized causes of Psoriasis, this without danger for health and by allowing at the same time an elimination of the symptoms and a decrease in the frequency of acute phases of Psoriasis (remission of Psoriasis).

There is therefore a real need to develop and formulate a composition for the treatment of Psoriasis, this composition being both safe for health and effective for treating in a global and simultaneous manner your three main recognized causes of Psoriasis in order to reduce in particular the frequency of remission of Psoriasis.

To solve this problem, there is provided according to the invention, a composition as indicated at the beginning, said composition comprising:

at least one antioxidant, in particular at least one antioxidant of the superoxide dismutase (SOD) type,

- Turmeric or at least one extract of Turmeric, in particular Curcuma longa or an extract of Turmeric longa, and

- from Boswellia or at least one extract from Boswellie, in particular Boswellia serrata or at least one extract from Boswellia serrata.

Turmeric (especially Turmeric longa) is known for its antioxidant properties helping the body to fight oxidative stress and maintain the effectiveness of natural defenses. It is also used as an anti-inflammatory and is arguably the most powerful natural anti-inflammatory identified to date.

Boswellia (in particular Boswellia serrata) is a tree whose resin constitutes a natural health product, in particular for treating inflammatory intestinal diseases (Crohn's disease, etc.) or joints. The effects of Boswellia are linked to boswellic acids, compounds in the resin that can reduce inflammation.

In the context of the present invention, it has been surprisingly determined that the three constituents of the composition, namely at least one antioxidant, Turmeric or at least one extract of Turmeric and Boswellia or at least one extract Boswellie, act in synergy so that the composition according to the invention treats in a global and simultaneous way the three main recognized causes of Psoriasis, this without danger for health and allowing at the same time an elimination of the symptoms and a reduction of the frequency of the acute phases of Psoriasis (remission of Psoriasis). It has therefore been determined that a composition according to the invention, in which each of the constituents is present in a bio-available form, allows a global and simultaneous treatment of all the inflammatory pathways responsible for Psoriasis, this for several types of Psoriasis.
