Guttate psoriasis is a skin condition in which small, red, scaly teardrop-shaped spots with a silvery scale appear on the arms, legs, and middle of the body. In addition to strep throat, the following may trigger an attack of guttate psoriasis:. Sometimes, it may become a chronic (lifelong) condition, or worsen to the more common plaque-type psoriasis. Figure 1 Acute guttate psoriasis on arms and trunk. One such trigger is infection, and one of the more common infectious agents is group A -hemolytic streptococcus (GABS). COM) More than 50 years ago, a study showed that in a series of 32 patients with acute guttate psoriasis (AGP; Figure 2), 56 had an antistreptolysin O (ASO) titer of 200 or more, and 31 had a history of sore throat 1 to 3 weeks before the appearance of the rash.7. Although the association between streptococcal infection and AGP is perhaps the most well described,8,10 strep infection has been shown to be associated with plaque11 as well as with pustular psoriasis.4. Guttate psoriasis is a type of psoriasis that looks like small salmon-pink drops on the skin. The trigger to the disease is often a streptococcal (bacterial) sore throat followed within two to three weeks by the eruption. The disease may recur if the person is a strep carrier (always carries streptococcal bacteria in his respiratory system). Psoriasis Psoriasis is a common and chronic skin disorder. Learn more.
Guttate psoriasis may be chronic and unrelated to streptococcal infection. Epidemiology. It is more common in individuals younger than 30 years. It is most often associated with streptococcal infection – two thirds have evidence of a recent streptococcal throat infection – but may also be associated with stress, trauma (K bner’s phenomenon) or drugs – eg, antimalarials, lithium, non-steroidal anti-inflammatory drugs, beta-blockers. Can talcum powder cause cancer? Guttate psoriasis causes a rash formed of drop-shaped salmon-pink areas on the chest, arms, legs and scalp. However, some people with guttate psoriasis develop the most common form of psoriasis, called plaque psoriasis. The trigger for the condition is usually a streptococcal (bacterial) throat infection. Small, salmon-pink (or red) spots usually appear suddenly on the skin two to three weeks after a streptococcal infection, such as strep throat or tonsillitis. Guttate psoriasis is characterized by the acute onset of small, 1-10 mm diameter, droplike, erythematous-to-salmon-pink papules, usually with a fine scale, as demonstrated in the images below. Guttate psoriasis is more common in individuals younger than 30 years. The sudden appearance of the papular lesions in response to streptococcal infection could either be the first manifestation of psoriasis in a previously unaffected individual or an acute exacerbation of long-standing plaque psoriasis. Lotus et al demonstrated that guttate psoriasis patients expressing the HLA-Cw 0602 allele were twice as likely to have positive streptococcal throat cultures.
Psoriasis, especially guttate forms, may be provoked or aggravated by streptococcal infection. Streptococci pneumoniae (pneumococci) are bacteria important in pneumonia and meningitis but rarely cause skin disease. Guttate psoriasis can cause numerous smaller lesions that have the same features as those of plaque psoriasis. For example, if you are infected with a streptococcal infection, the immune system generates antibodies to counter streptolysin-0 which is present on the bacteria causing the infection. Upper respiratory and strep throat infection are common, but not everyone suffering from them contracts guttate psoriasis. Guttate psoriasis is most often triggered by upper respiratory infections (for example, a sore throat caused by streptococcal bacteria). However, many other conditions, including colds, chicken pox and tonsillitis, have been found to trigger attacks of guttate psoriasis.

Proposed criteria for the diagnosis includes evidence of prior strep infection, a non migratory arthritis, recurrent or protracted arthritis and arthritis not highly responsive to NSAIDs. Streptococcal infection is the most common identifiable cause in children. EN occur 2-3 weeks after streptococcal infections, obtaining throat cultures, ASO and Anti DNAse B titers at presentation is important. Guttate psoriasis is characterized by sudden onset of diffuse red scaly papules that often resolve spontaneously but at times progress to chronic plaque psoriasis.122 The etiology is unknown.
