Clinical characteristics of rare Streptococcal pneumonia disease in children / 中华实用儿科临床杂志

The clinical manifestations of Streptococcus pneumoniae disease(SPD) are various, and some patients with rare SPD types have a worse prognosis.Among them, the mortality is up to 70% after 48-72 hours of the onset of Streptococcus pneumoniae (SP)-related overwhelming post-splenectomy infection(OPSI). Purpura fulminans of SP(SP-PF) is often characterized by extensive purpura, fever, hypotension and disseminated intravascular coagulation, and prognosis of the patients without prodromal symptoms is poor.Infectious endocarditis has a mortality rate of 20.7% in SP-related cardiovascular diseases, and Austrian syndrome has a fatality rate of 43.5%.The mortality rate of bacterial pericarditis was 13.56%.At present, SP vaccine can not completely cover the 7 serotypes reported.Vasculitis mainly occurs in the thoracic and abdominal aorta and its branches, middle cerebral artery and so on.Of the 8 cases of hemophagocytic syndrome, 2 cases died.Early anti-infection, methylprednisolone shock and surgical treatment can improve the prognosis.Vaccination and drug prophylaxis can help those with under-lying diseases such as splenic dysfunction to reduce the incidence of SPD, such as SP-OPSI.
