Psoriasis

Warning

Psoriasis: A common, chronic, inflammatory skin disorder that is characterized by scaly plaques affecting scalp, elbows, knees and sacrum but in more severe forms can affect any part of the body. Incidence up to 2% of the UK population. Nail changes including pitting, onycholysis and sub-ungual hyperkeratosis may be seen in 50% and an inflammatory polyarthritis in up to 14%. Palmoplantar pustulosis (PPP) is characterized by crops of sterile pustules on the palms and soles that erupt repeatedly over months or years and is strongly associated with smoking. Guttate psoriasis consists of a widespread eruption of many small scaly plaques and often follows a streptococcal throat infection. Generalised pustular psoriasis with background erythema studded with small pustules is a rare but severe form of psoriasis that may be life threatening. Psoriasis is a systemic disorder associated with an increased risk of cardiovascular disease; always assess cardiovascular risk factors. 

Not all treatment options may be listed in this guidance. Please refer to local formulary for a complete list.

Treatment/ therapy

Mild: localised plaques with limited impact on quality of life usually managed with topical treatment 

Assess lifestyle factors that may precipitate or aggravate psoriasis i.e. smoking, alcohol, obesity, certain medications and infections. 

 

Emollients – prescribe to soften scale (use fingertip measurement) 

 

Vitamin D with Steroid combined: 

  • Ointment, Cream, Gel, Foam: Apply OD for 4 weeks, review and repeat as necessary 

Calcipotriol with Betamethasone preparations:  

Non-branded ointment

NB: Calcitriol and Tacalcitol may be less irritating than Calcipotriol and may be more suitable for sensitive areas like face and genitals. 

 

Topical Corticoteroids: 

  • Mild: OD facial psoriasis 

Moderately potent: OD face and flexural areas 

Potent:  OD trunk/limbs, BD palms/soles 

 

Coal Tar Preparations: 

  • Cream-Psoriderm® apply OD/BD

Cocois® ointment 100G apply up to OD 

Sebco® ointment 100G apply up to OD

Moderate psoriasis: Localised site or more widespread psoriasis > 10% body area 

Scalp psoriasis:  

  • Prescribe a regimen of coconut, tar and salicylic ointment (Sebco/Cocois) applied OD for an hour or overnight and wash off with tar-based shampoo to soften and remove thick scale. Reduce frequency as improves. 
  • Apply potent or very potent topical corticosteroid scalp solution / gel / foam (e.g. betamethasone +/- salicylic acid, clobetasol) OD after shampooing or, Vitamin D preparation, gel / foam OD, or corticosteroid + vitamin D (e.g. Dovobet® gel). 

 

Facial/Flexural psoriasis: 

  • Steroids: mild/moderate potency topical corticosteroid OD 

Vitamin D preparations: Calcitriol / Tacalcitol OD/BD may be used as less irritant than Calcipotriol

Calcipotriol with Betamethasone combination ointment OD 

 

Guttate Psoriasis: 

  • Widespread small plaques, self-limiting, often triggered 7-10 days after streptococcal URTI.  

Will often resolve spontaneously in weeks to months, useful treatments include: 

Mildly potent topical corticosteroid OD 

Vitamin D preparations OD 

Coal tar preparations OD 

 

  • Refer to secondary care for consideration of phototherapy and/or first line systemic therapy with Methotrexate, Ciclosporin or Acitretin for moderate to severe psoriasis failing to respond to treatment. 

 

Treatment failures with phototherapy and first line systemic therapies may require novel systemic therapy with phosphodiesterase type-4 inhibitor (Apremilast) or biologic therapies. 

Severe psoriasis: Widespread inflamed psoriasis or severe localised recalcitrant psoriasis (e.g. palms and soles) or affecting high impact sites like face or groin. 

Refer same day to dermatology/ emergency care for erythrodermic or generalised pustular psoriasis 

 

Refer to rheumatology if any evidence of psoriatic arthropathy. 

Referral Management

Mild: localised plaques with limited impact on quality of life usually managed with topical treatment 

  • Manage in primary care.  

Moderate psoriasis: Localised site or more widespread psoriasis > 10% body area 

  • Refer routinely to secondary care service if failure of appropriate topical treatment after 4 weeks  

Severe psoriasis: Widespread inflamed psoriasis or severe localised recalcitrant psoriasis (e.g. palms and soles) or affecting high impact sites like face or groin.

  • Consider referring urgently if psoriasis is very widespread and inflamed 
  • Emergency referral is indicated for erythrodermic or generalised pustular psoriasis. 
  • Refer to rheumatology if any evidence of psoriatic arthropathy.

Clinical tips

  • Patient preference for type of topical preparation should guide effective treatment 
  • Psoriasis is a systemic disorder associated with an increased risk of cardiovascular disease; always assess cardiovascular risk factors.
