Tolerance and efficacy of a new celastrol-containing balm as adjunct care in psoriasis

Exploring the Therapeutic Potential of Natural Compounds in Psoriasis and Their Inclusion in Nanotechnological Systems

Psoriasis is a chronic inflammatory disease that affects around 2-3% of the world's population. The treatment for this autoimmune disease still remains centered around conventional methods using synthetic substances, even though more recent advancements focus on biological therapies. Given the numerous side effects of such treatments, current research involves plant extracts and constituents that could prove useful in treating psoriasis. The aim of this narrative review is to highlight the most known representatives belonging to classes of natural compounds such as polyphenols (e.g., astilbin, curcumin, hesperidin, luteolin, proanthocyanidins, and resveratrol), alkaloids (e.g., berberine, capsaicin, and colchicine), coumarins (psoralen and 8-methoxypsoralen), and terpenoids (e.g., celastrol, centelloids, and ursolic acid), along with plants used in traditional medicine that could present therapeutic potential in psoriasis. The paper also provides an overview of these compounds' mechanisms of action and current inclusion in clinical studies, as well as an investigation into their potential incorporation in various nanotechnological systems, such as lipid-based nanocarriers or polymeric nanomaterials, that may optimize their efficacy during treatment.

Tripterygium wilfordii Hook. F. and Its Extracts for Psoriasis: Efficacy and Mechanism

Psoriasis is an inflammatory autoimmune skin condition that is clinically marked by chronic erythema and scaling. The traditional Chinese herb Tripterygium wilfordii Hook. F. (TwHF) is commonly used in the treatment of immune-related skin illnesses, such as psoriasis. In clinical studies, PASI (Psoriasis Area and Severity Index) were dramatically decreased by TwHF and its extracts. Their benefits for psoriasis also include relief from psoriasis symptoms such as itching, dryness, overall lesion scores and quality of life. And the pathological mechanisms include anti-inflammation, immunomodulation and potentially signaling pathway modulations, which are achieved by modulating type-3 inflammatory cytokines including IL-22, IL-23, and IL-17 as well as immune cells like Th17 lymphocytes, γδT cells, and interfering with IFN-SOCS1, NF-κB and IL- 36α signaling pathways. TwHF and its extracts may cause various adverse drug reactions, such as gastrointestinal responses, aberrant hepatocytes, reproductive issues, and liver function impairment, but at adequate doses, they are regarded as an alternative therapy for the treatment of psoriasis. In this review, the effectiveness and mechanisms of TwHF and its extracts in psoriasis treatment are elucidated.

[Influence of an adjuvant treatment with an emollient containing 10 % urea, ceramides, glycerin und glyceryl glucoside in patients with psoriasis vulgaris]

BACKGROUND

Guidelines generally recommend an adjuvant treatment with emollients for patients suffering from psoriasis. However evidence for this purpose is limited.

PATIENTS AND METHODS

We performed a prospective observational study with an emollient containing 10% urea, ceramides, glycerin and glyceryl glucoside in patients suffering from mild to moderate psoriasis. The patients had to be stable for at least 12 weeks on prior antipsoriatic therapy including topical therapy, systemic treatment or phototherapy which was continued during the trial.

RESULTS

A 4-week daily application of the emollient resulted in significant improvement regarding quality of life (measured by DLQI, Dermatology Life Quality Index) and clinical outcome (measured by local PASI, Psoriasis Area and Severity Index) among the treated patients.

CONCLUSION

The trial results show that a daily adjuvant treatment with emollients can support a basic antipsoriatic therapy both in aspects of clinical efficacy and quality of life in mild to moderate patients suffering from psoriasis.
