Polyarthritic forms are indicated if 5 or more joints are affected within the
first 6 months of the disease.
Psoriatic arthritis is a kind of arthritis with psoriatic lesions of the skin and
nails, especially at the joints of fingers and toes.
Psoriasis is a common chronic skin disease, characterised by red patches
covered by thick, dry, silvery, adherent scales.

people] cause a sharp fall in white blood cells (agranulocytosis) and
severe bone marrow suppression
unexpected bleeding, e.g. bleeding gums, blood in the urine,

number of blood platelets caused by severe courses of bone marrow
depression [very rare - may affect up to 1 in 10,000 people]
severe skin rash or blistering of the skin (this can also affect your
mouth, eyes and genitals); these may be signs of the very rare [may
