Psoriasis and gout
  1. J. N. Fordham,

    Ten cases of gouty arthritis are described in association with psoriasis. Eight were receiving intensive inpatient treatment for their skin condition. Diagnosis was based on clinical grounds or, in 3 cases, by compensated polarizing microscopy (CPM) of synovial fluid. All patients were male and 5 of them had conditions other than psoriasis known to predispose to hyperuricaemia. The patients appeared to fit into three groups: five had typical lower limb gout occurring in conjunction with long-standing extensive psoriasis; 3 patients had preceding features of inflammatory synovitis, one of whom subsequently developed typical distal interphalangeal involvement of peripheral psoriatic arthritis; two patients appeared to have coincident gout and psoriasis.

    We believe that an association of gout with extensive long-standing psoriasis may exist particularly in male patients with an additional cause for hyperuricaemia. Long-term studies of a large population of psoriatics are required. Previous reports may have underestimated the incidence of gout because of failure to examine synovial fluid for crystals particularly from those patients with a subacute large joint arthropathy.
