| 1 | 西宾夕法尼亚州风湿热病例持续高发现象的研究:对于可能导致风湿病的化脓性链球菌进行emm分型显示文摘Objective:To evaluate the occurrence of cases of acuterheumatic fever (ARF) in western Pennsylvania although there has been a marked reduction of cases of ARF in the United States overall. Study design:From 1994 to 2003,the cases of ARF evaluated at Children’s Hospital of Pittsburgh were reviewed. In addition,throat cultures were performed on asubset of these children and their family members beginning in 1995. Molecular typing was performed on isolates of the group A streptococcus (GAS) recovered,using field inversiongel electrophoresis (FIGE) and emm typing. Results:There were 121 new cases of ARF from 1994 to 2003. Of these,57%were male. The median age was 10 years. The majority of children (57%) had carditis with or without another manifestation of ARF. The results of throat cultures were available for 231 persons; 36%(30/84) of the children with ARF and 14%(20/147) of family members were positive for GAS. Eight emm types were observed (emm 1,2,6,12,18,28,75,and 89).Data suggest that emm type 12 may be a rheumatogenic strain.Conclusion:ARF remains a problem in western Pennsylvania.Identification of emm types associated with cases should enlighten vaccine development. | Martin J.M.
