Definitions
- the present invention relates to the field of rosacea treatment.
- the invention aims to provide new pharmaceutical compositions, more particularly dermatological, useful for the treatment of rosacea and comprising as active agent a compound modifying and / or inhibiting the secretion of at least one interleukin chosen from the group comprising Interleukin 5, Interleukin 6 and Interleukin 10.
- Rosacea is a common chronic and progressive inflammatory dermatosis linked to vascular relaxation. It mainly affects the central part of the face and is characterized by reddening of the face or hot flushes, facial en / theme, papules, pustules, and telangiectasia. In severe cases, especially in humans, the soft tissue in the nose can swell and produce a bulbous swelling called rhinophyma.
- Rosacea usually occurs between the ages of 25 and 70, and is much more common in fair skinned people. It affects more particularly women, although this condition is generally more severe in men. Rosacea is chronic and persists for years with periods of exacerbation and remission.
- Rosacea was originally called "acne rosacea” because its papules (slight raised skin) and inflammatory pustules (scabs of pus) are very similar to those of acne vulgaris.
- the etiology of which is based on both abnormal keratinization, increased sebum production and bacterial inflammation, inflammation of rosacea is vascular in nature and poorly understood.
- the result of this facial vascular anomaly is a permanent edema of the dermis which could accompany increased colonization by Demodex folliculorum, a mite that is usually found in the follicles of the face.
- Demodex folliculorum has an etiological role in rosacea (Erbagi et al., 1998, Int J Dermatol, vol.37, pages 421-425; Purcell et al, 1986, J Am Acad Dermatol, vol.15, pages 1159-1162; Sibenge et al., 1992, J Am Acad Dermatol, vol. 26, pages 590-593). It seems that Demodex folliculorum causes or worsens inflammatory reactions, resulting in papules and pustules, by blocking the pilosebaceous follicles of the face (Roihu et al., 1998, J Cutan Pathol, vol.25, pages 550-552 ).
- rosacea The pathogenesis of rosacea is poorly understood. Many factors can be involved without necessarily inducing this condition. These are for example psychological factors, gastrointestinal disorders, environmental factors (exposure to the sun, temperature, humidity) and emotional factors (stress), food (alcohol, spices), hormonal, vascular, or even infection with Helicobacter pilori.
- stage 2 erythematato-telangiectatic (around 30 years).
- the malar areas are diffusely red.
- the chin and the middle part of the forehead can be affected.
- the work of the Applicant has made it possible to highlight the involvement of certain interleukins in rosacea, and more particularly the involvement of interleukin 5, interleukin 6 and interleukin 10 in rosacea.
- the humoral immune response involves activation of type 2 helper T cells (Th2).
- Th2 type 2 helper T cells
- the differentiation of naive T cells into Th2 cells is induced by interleukin 6.
- Th2 cells then produce interleukin 4, interleukin 5 and interleukin 10, which stimulate the activation of B cells and the production of antibody.
- Interleukin 5 also called "eosinophil colony stimulating factor”
- eosinophil colony stimulating factor is secreted by T lymphocytes. It can be classified as hematopoietic growth factors because it stimulates growth, differentiation and activity eosinophils which play an important role in the fight against parasitic infections.
- Interleukin 5 also acts on eosinophils as an agent chemotactic. IL-5 induces the proliferation of B lymphocytes and their secretion of immunoglobulins.
- Interleukin 6 also called “hepatocyte stimulating factor”, “hybridoma growth factor” or “B cell stimulating factor” is a glycoprotein secreted in particular by T cells, monocytes and fibroblasts. It stimulates the growth and differentiation of B cells into plasma cells and increases the generation of platelets. It activates, by activation of hepatocytes, the secretion of inflammation proteins such as fibrinogen and reactive protein C. It has a pro-inflammatory role.
- Interleukin 10 is produced by T cells, B cells and mast cells. IL-10 acts in particular at the level of B lymphocytes: increase in the viability of small B lymphocytes and increase in the expression of HLA class II molecules. This interleukin is also involved in the regulation of mast cell proliferation.
- the work of the Applicant has made it possible to demonstrate the usefulness of the compounds modifying the secretion of at least one interleukin chosen from the group comprising interleukin 5, interleukin 6 and interleukin 10 in the treatment of rosacea. .
- This has been noted by the use of metronidazole which results in a modification of the secretion of interleukins, and more particularly of the secretion of IL-5, IL-6 and IL-10. It has also been found that the use of metronidazole results in an inhibition of the secretion of interleukins, and more particularly of the secretion of IL-5, IL-6 and IL-10.
- the invention aims to offer a new method of treating rosacea consisting in administering to a subject suffering from rosacea, an effective amount of a compound modifying and / or inhibiting the secretion of at least one chosen interleukin in the group comprising IL-5, IL-6 and IL-10.
- the invention relates more particularly to the use of a compound which modifies, and advantageously inhibits, the secretion of at least one interleukin chosen from the group comprising IL-5, IL- 6 and IL-10, for the preparation of a pharmaceutical composition intended for the treatment of rosacea.
- the invention also relates to the use of a compound modifying, and advantageously inhibiting, the secretion of two or three interleukins chosen from the group comprising IL-5, IL-6 and IL- 10, for the preparation of a pharmaceutical composition intended for the treatment of rosacea.
