Although the relationship between streptococcal tonsillitis and acute
guttate psoriasis is well recognized, its relationship to chronic form
s of psoriasis is less established. In order to explore this further,
the authors questioned 35 patients with severe psoriasis and 35 age-ma
tched eczema controls about their history of significant sore throats
(i.e, requiring a GP visit) and any resultant worsening of the skin co
ndition. A third of the psoriasis patients reported recurrent sore thr
oats which worsened their skin condition. This was true of only one (3
%) of the 35 eczema controls. The authors discuss these findings in th
e context of recent laboratory work on the association between strepto
coccal infection and psoriasis.
