The role of streptococcal infection in the initiation of guttate psoriasis

Frequency of streptococcal upper respiratory tract infections and HLA- Cw*06 allele in 70 patients with guttate psoriasis from northern Poland

“…The frequency of HLA- Cw*06 allele in the present study group was 70% vs. 30% in controls ( p = 0.001). Seven out of 34 (21%) patients with streptococcal induced guttate psoriasis did not carry HLA- Cw*06 allele, which is concordant with other studies [ 6 , 13 ].…”

Antibiotic Exposure, Infection, and the Development of Pediatric Psoriasis

“…However, the imprecise estimates from this small model (<25% of the overall cohort) did not significantly differ from one another. Overall, our findings support prior literature that infections may play a role in the development of psoriasis 5,7,9 but suggest that antibiotics do not substantially, independently contribute to this risk.…”

“…Our data also support previous research linking group A pharyngitis specifically with guttate psoriasis. 4,5 In addition, skin infections were associated with psoriasis in our study. It is unclear to what extent this finding reflects misdiagnosis of early psoriasis as infection, misdiagnosis of an infection-related skin diseaseas psoriasis (eg, molluscum contagiosum dermatitis, pityriasis rosea), or whether skin infections may trigger psoriasis in children.…”

Association of Streptococcus with Guttate Psoriasis: An Observational Study at Two Tertiary Care Hospitals in Dhaka

“…Among these above mentioned studies showed significant difference in culture results in AGP versus controls. Culture result of this present study were nearly similar with above mentioned others studies findings 4,6,12,15 . Confirmation of Streptococcal infections in psoriasis may be difficult because patients are often seen in the convalescent phase when antibiotics have already been taken and throat swab culture are more likely to be negative.…”
