The value of serum amyloid protein A in the early diagnosis of neonatal sepsis and necrotizing enterocolitis / 中国感染控制杂志

ABSTRACT

Early/late onset sepsis(EOS/LOS)and necrotizing enterocolitis(NEC)are common diseases during the neonatal period,with poor prognosis in severe cases.The early clinical manifestations are not specific,the diag-nosis is difficult,currently-used non-specific laboratory tests(C-reactive protein,procalcitonin,etc.)have disad-vantages,which may lead to missed diagnosis or misdiagnosis.Serum amyloid A(SAA)is a novel acute phase re-actant that increases significantly in the early stage of EOS/LOS and NEC,and lasts for a long time,it is related to the severity of the disease and can reflect the therapeutic effect,thus it can be used as a biomarker for diagnosis and treatment of these two diseases.This paper reviews SA A and its value in the early diagnosis of EOS/LOS and NEC,providing new references for the diagnosis and treatment of such diseases.
