The itch-inflammation loop
Barrier disruption, type-2 inflammation, sensory-nerve sensitisation and scratching damage can reinforce one another. The 2026 PLA2G2F/P-LPE study suggests epidermal lipid metabolism may add another amplification layer.
Research targets are not ready-made treatments
Moisturisers, topical anti-inflammatory treatment, biologics and JAK inhibitors are selected according to age, severity, site, infection and comorbidity. A new laboratory target does not replace established care.
Useful notes before a consultation
- Sleep disruption and itch frequency
- Affected sites, duration and triggers
- Names, amounts and frequency of topical medicines
- Oozing, pain or fever suggesting infection
FAQ
Should severe itch simply be tolerated?
No. It can disrupt sleep and worsen scratching damage, and should be discussed with a clinician.
Can supplements target this pathway?
The study does not show that supplements reproduce a therapeutic effect.
