CASE PRESENTATION: Here we describe two pediatric cases of S. pyogenes endocarditis with associated toxic shock. Case 1 was a previously well Caucasian 6-year-old female who presented with sepsis. [ncbi.nlm.nih.gov]

• Varicella-Zoster Virus Infection

  Despite the dramatic increase in invasive Streptococcus pyogenes infections associated with varicella zoster virus infections in recent years, post-varicella S. pyogenes meningitis occurs very rarely. [ncbi.nlm.nih.gov]

• Severe Clinical Course

  Most importantly, it is concluded that recurrent otitis media has to be treated carefully following appropriate identification of the causing organism in order to prevent severe clinical courses of streptococcal infections. [ncbi.nlm.nih.gov]

• Systolic Murmur

  In spite of the improvement of her unconscious state, she developed a new-onset systolic murmur on day 13, and echocardiography revealed severe mitral valve regurgitation with vegetation. [ncbi.nlm.nih.gov]

• Retinal Lesion

  However, after the discontinuation of the antibiotics and prednisolone, the retinal lesion became more vasoproliferative and caused leakage to reduce the vision again. The leakage was remedied by laser photocoagulation to the retinal lesion. [ncbi.nlm.nih.gov]

• Intertrigo

  Abstract We report a 12-month-old infant girl with cervical intertrigo caused by Streptococcus pyogenes. This form of intertrigo has been reported in only five children, but it is clearly underestimated. [ncbi.nlm.nih.gov]

• Salpingitis

• HLA-Cw6

  Moreover, a higher TH17 response was observed in cells isolated from patients with flares associated with a streptococcal tonsillitis and with the HLA-Cw6 allele (cohort 1). [ncbi.nlm.nih.gov]

Eleven strains caused recurrent pharyngitis within 40 days after the last treatment, all of them showing the same PFGE-type as the primary strains. Eight of the strains caused recurrence more than 40 days after the treatment. [ncbi.nlm.nih.gov]

The pathogenesis of this invasive infection, as well as predictors of poor prognosis are discussed. [ncbi.nlm.nih.gov]

It is the etiological factor of the upper respiratory tracts infections (pharyngitis, otitis media, sinusitis, pneumonia), as well as skin and soft tissues infections, which may lead to necrotising fasciitis, arthritis and meningitis. [czytelniamedyczna.pl]

The Thomsen- Friedenreich antigen (T antigen) plays a role in the pathophysiology of pneumococcal HUS. We describe the case of a 3-year-old boy with GAS-associated HUS and show how T-antigen exposure was implicated in this case. [ncbi.nlm.nih.gov]

Further studies are needed to determine whether ProT is the pathophysiological target zymogen of SfbX(1-312), to delineate the natural substrate of the SfbX(1-312)·ProT complex, and to elucidate the role of SfbX in the pathology of S. pyogenes infection [bloodjournal.org]
