Definitions
- the present invention relates to avocado unsaponifiable or to a composition comprising avocado unsaponifiable for its use in the prevention and/or treatment of pathologies and disorders induced by a yeast of the Malassezia genus.
- the present invention also relates to the cosmetic use of avocado unsaponifiable or a composition comprising avocado unsaponifiable for the prevention and/or treatment of dandruff.
- the invention relates to a process for preparing avocado unsaponifiable.
- the human microbiome includes multiple and diverse microorganisms such as bacteria, viruses and fungi.
- the yeast Malassezia which is part of the Basidiomycetes, is part of the human commensal flora, particularly on the scalp. This yeast releases hydrolases, such as lipases and phospholipases C, which allow the production of fatty acids from the lipids of the yeast host.
- hydrolases such as lipases and phospholipases C, which allow the production of fatty acids from the lipids of the yeast host.
- the yeast Malassezia invades the stratum corneum and the free fatty acids generated by the release of lipases cause an inflammatory process.
- Inflammation leads to hyper-proliferation of the stratum corneum and incomplete differentiation of comeocytes, which impairs the functions of the stratum corneum, notably its barrier function, resulting in easier access for the yeast Malassezia.
- the Malassezia yeast is involved in many skin conditions, such as seborrheic dermatitis, Malassezia folliculitis, scalp dandruff, pityriasis capitis and even pityriasis versicolor.
- Seborrheic dermatitis is a fairly common benign chronic erythemato-scaly inflammatory dermatosis which develops in outbreaks and most often affects the scalp and face, particularly the nasolabial folds and eyebrows.
- One of the typical forms affects infants and manifests itself as yellow crusts of the scalp (cradle cap) or face.
- Cradle Cap is a form of infantile seborrheic dermatitis (ISD) presenting erythematous plaques with fatty scales of the scalp and whose incidence is highest in the third month of the patients' life.
- ISD infantile seborrheic dermatitis
- the factors for the appearance of cradle cap are diverse. Hyperproduction of sebum can be one of these factors without being a necessary cause of their appearance: it causes the adhesion of dead comeocytes to the surface of the skin and prevents their physiological desquamation. Invasion of the stratum corneum by the yeast Malassezia as described above is another of these factors.
- the therapeutic strategy used in the treatment of seborrheic dermatitis aims to regulate the production of sebum, calm inflammation of the skin and reduce the development of the Malassezia yeast.
- This treatment involves the use of anti-inflammatories such as topical corticosteroids and antifungals such as ketoconazole, lithium gluconate or cyclopiroxo lamin.
- Treatment may also involve emollients such as mineral or olive oils or petroleum jelly and keratolytics such as salicylic acid.
- the treatments of choice for pathologies and disorders induced by a yeast of the Malassezia genus are antifungal and anti-inflammatory treatments.
- the action on sebum production is generally not sufficient to treat pathologies and disorders induced by yeast of the Malassezia genus.
- seborrheic production does not prevent the start of an abnormal growth cycle of yeasts of the Malassezia genus.
- a treatment acting solely on the production of sebum for example by inhibiting the activity of 5-alpha reductase, cannot constitute a treatment of choice for these disorders.
- sebum production is not only controlled by the 5-alpha reductase pathway, it can be activated by other pathways or other causes such as physical or psychological stress.
- Prolonged use of corticosteroids may result in side effects such as skin atrophy, striae, telangiectasia, folliculitis, hypopigmentation, and habituation, and prolonged use of antifungals may result in side effects such as contact dermatitis; in addition, other treatments have limitations of use; for example, lithium gluconate is only indicated in the treatment of immunocompetent adults.
