Senile / xerotic pruritus

Xerotic pruritus · winter itch · pruritus senilis · asteatotic pruritus · pruritus of the elderly

Senile pruritus is generalised itch in the elderly without primary cutaneous lesions, most commonly attributable to xerosis (asteatosis), neurogenic deconditioning, polypharmacy and concurrent systemic disease. Up to 50% of adults over 65 report chronic itch. While many cases reflect xerosis, >6 weeks of generalised itch warrants exclusion of underlying malignancy (Hodgkin, CTCL, internal carcinoma), cholestatic / renal disease and iron deficiency.

Pathogenesis

  • Age-related changes:
    • Xerosis: reduced sebaceous and sweat gland activity, decreased filaggrin / NMF; impaired barrier.
    • Reduced cutaneous nerve density; rerouted neurogenic itch pathways.
    • Reduced sensitivity to cooling sensation contributes to relative warming-itch.
  • Risk factors:
    • Polypharmacy (PPIs, opioids, statins, calcium-channel blockers, ACEi).
    • Chronic renal failure (uraemic itch).
    • Cholestatic liver disease.
    • Thyroid disease.
    • Iron deficiency.
    • Cancer (Hodgkin, CTCL, internal).
    • Cognitive impairment may mask depression-related itch / neuropathic disease.
    • Winter / dry indoor heating.

Clinical features

  • Generalised itch without primary skin lesions.
  • Secondary lichenification, excoriation, prurigo nodules can develop.
  • Xerosis (eczema craquelé pattern — crazy-paving) on lower legs / extensor arms.
  • Itch worse at night, after bath, during winter, in central-heating environments.
  • No fever, weight loss, lymphadenopathy (if present, prompt malignancy workup).
  • Affects up to 50% of UK adults >65 years; chronic course.

Workup

  • Full clinical history, drug history, review of systems.
  • Examination — lymphadenopathy, hepatosplenomegaly, jaundice, neurology, skin lesions.
  • Bloods: FBC + blood film, U&E, LFT, calcium, ferritin, B12, folate, TFT, ESR, CRP, LDH.
  • Serum protein electrophoresis if myeloma suspected.
  • HIV, hepatitis screen.
  • Chest X-ray if persistent itch >6 weeks or lymphadenopathy.
  • CT chest / abdomen / pelvis if systemic features.
  • Skin biopsy if any lesional component, especially with TCR gene rearrangement to exclude MF.
  • Age-appropriate cancer screening.

Differentials

  • Bullous pemphigoid (pre-bullous urticarial phase) — common in elderly; consider DIF if pruritus is intense.
  • Scabies, pediculosis.
  • Mycosis fungoides — biopsy + TCR.
  • Pruritus of malignancy.
  • Atopic / asteatotic / contact dermatitis.
  • Drug-induced pruritus.
  • Brachioradial pruritus, notalgia paraesthetica — neuropathic, regional.
  • Iron deficiency / anaemia.
  • Psychogenic / depression-associated itch.

Management

  • General measures:
    • Lukewarm short baths / showers; avoid hot water.
    • Soap substitutes (aqueous cream alternatives; emollient cleansers).
    • Liberal emollients with humectants (urea 5-10%; lactic acid 5%).
    • Humidify rooms; avoid central heating extremes.
  • Drug review: rationalise polypharmacy.
  • Topical:
    • Mid-potency topical corticosteroid 1-2 weeks for excoriated areas.
    • Menthol 1-2% in aqueous cream for cooling effect.
    • Capsaicin 0.025-0.075% for localised itch.
    • Topical calcineurin inhibitors (tacrolimus / pimecrolimus) for steroid-sparing.
  • Systemic:
    • Sedating antihistamines for sleep (hydroxyzine, doxepin) — caution in elderly (falls).
    • Gabapentin 100-1200 mg daily for neuropathic / uraemic itch.
    • Mirtazapine 15-30 mg nocte for refractory.
    • Dupilumab for refractory chronic pruritus (off-label; emerging evidence).
    • Treat underlying systemic cause.
  • Phototherapy: NBUVB for refractory cases.
  • Counsel:
    • Chronic relapsing course.
    • Vigilance for emergence of primary lesions (CTCL, BP, MF).
    • Address bath / shower / heating environment.
