Group A streptococcus (GAS) causes a variety of human infections. It is also an uncommon but serious cause of postpartum infections. In contrast to group B streptococcus (GBS) infection, which causes illness and death in newborns disproportionately more often than it does in mothers, perinatal GAS infection primarily affects mothers . Invasive GAS infection is defined by the isolation of GAS from a normally sterile site (e.g., blood) or by the isolation of GAS from a nonsterile site in the presence of the streptococcal toxic shock syndrome or necrotizing fasciitis. A postpartum case of invasive GAS is defined as isolation of GAS during the postpartum period, in association with a clinical postpartum infection (e.g., endometritis) or from either a sterile site or a wound infection.
Because of the burden and severity of invasive GAS infection, the Centers for Disease Control and Prevention (CDC) hosted a meeting in to formulate guidelines for responding to postpartum and postsurgical GAS infections. However, we could not find any recommendations for long-term follow-up of patients who had GAS infection subsequent to delivery or gynaecological procedures, or further recommendations regarding subsequent delivery or gynaecological invasive procedures. It is possible that women who had GAS as a cause of vaginal infection may have a tendency to be carriers of this organism, but this has never been proven. We believe it is of importance to determine if women who have had one infection may be long-term carriers which may pose a risk during future pregnancies.
The objective of the present study is to evaluate the incidence of long term gynaecological carrier state of patients who had GAS invasive infection following delivery, and to provide guidelines for follow-up and treatment of such patients.
The proposed study may answer the question whether this endogenous GAS origin represents chronic GAS carrier state, similar to the known GBS carrier state. As some of these patients had severe infections (sometimes life threatening) a protocol for long-term follow up and management is necessary in case an invasive procedure is done (IUD insertion, endometrial biopsy, curettage or delivery) in order to prevent recurrent infection. The information collected in the study will enable us to afford recommendations for follow up and prophylaxis in the future.
Research plan The study population will include patients diagnosed with GAS invasive infection following delivery or gynaecological procedures (such as endometrial biopsy, D&C or IUD insertion) at Hadassah university hospitals, and patients in whom an isolation of GAS from the vagina without infection was reported. The study will consist of two parts, prospective and retrospective.
