Moderate-to-severe plaque psoriasis - Modern management for GPs
This clinical guide for general practitioners outlines the modern management of moderate-to-severe plaque psoriasis. It emphasizes the link between psoriasis and cardiovascular disease, metabolic syndrome, and mental health, while providing criteria for specialist referral.
Why it matters
Improving primary care management of chronic skin conditions can significantly reduce long-term health complications and improve patient quality of life.
Plaque psoriasis affects ~2% of the population and is linked to cardiovascular disease (CVD), psoriatic arthritis (PsA), metabolic syndrome, NAFLD, and depression/anxiety—burdens that rise with skin severity
Contemporary reviews and meta-analyses consistently associate psoriasis with increased CVD events; major societies now treat psoriasis as a CVD risk enhancer warranting aggressive risk-factor control.
Recognising moderate–to–severe disease in clinic Severity is more than “% BSA”. Practical triggers to consider systemic therapy and/or refer include:
Rule of thumb: if plaques are painful/itchy, recurrently infected/fissured, or function-limiting (manual work, sexual function), treat as ≥moderate regardless of BSA and refer.
Ask about joint pain/swelling, enthesitis, back pain, and nail disease. Use PEST (5 questions; ≥3 → refer to rheumatology).
Treat psoriasis as a CVD risk enhancer: measure BP, lipids, HbA1c; stop smoking; weight management; consider statin/ACEI per standard indications.
Depression/anxiety are common and improve with effective skin control; screen and treat per guidelines.
