Psoriasis and AMD: a new study suggests an increased eye risk

Psoriasis and AMD: a new study suggests an increased eye risk

A US retrospective study (University of Rochester, TriNetX network, 22,901 patients >55, EADV 2025 congress) associates psoriasis with an increased risk of age-related macular degeneration (AMD): up to +56% overall risk depending on the control group, +40% wet AMD, +13% dry AMD. Patients on biologics had a 27% lower risk. Observational study: it shows an association, not causation, and shares common factors (age, smoking, inflammation, metabolic disorders). No universal screening recommended at this stage; visual vigilance and control of risk factors in older patients.

Biologic treatments and hair loss: adverse effect, paradoxical immune reaction or consequence of the disease?

Biologic treatments and hair loss: adverse effect, paradoxical immune reaction or consequence of the disease?

Hair loss under biologic treatment is real but rare and heterogeneous: telogen effluvium, paradoxical alopecia areata, inflammatory scalp psoriasis, infection or (rarely) scarring alopecia. The best-established signal concerns anti-TNF drugs (French pharmacovigilance: 52 cases, reporting odds ratio 3.0), rather a class effect. Dupilumab, on the contrary, can promote regrowth in some atopic patients. The right question is not 'should the biologic be stopped?' but 'which alopecia is it, is there another cause, and is the follicle threatened?'.
