Â
I'd have to dig up all the research I originally did 3 years ago, but here are some results from some Googling:
Â
http://mothering.com/pregnancy-birth/treating-group-b-strep
Â
"Some studies have shown a decrease in GBS infection in newborns whose mothers accepted IV antibiotics during labor, but no decrease in the incidence of death.8, 9 Still other research has found that preventive use of antibiotics is not always effective.10 In fact, one study found no decrease in GBS infection or deaths among newborns whose mothers were given IV antibiotics during labor.11"
Â
The article sites is sources, so you can refer directly to the studies.
Â
"6 percent of those who develop a GBS infection will die"
Â
http://www.aafp.org/afp/2006/0901/p875.html
(They are getting the below from this CDC report:)
http://www.cdc.gov/mmwr/preview/mmwrhtml/mm5447a2.htm
Â
"Of term infants, 4 percent with early-onset infections died, whereas no infants with late-onset infection died."
Â
(again, that is of those who DID get infected & we've already agreed taht the % of babies who will actually become infected with GBS to an untreated mother is relatively low.)
Â
http://www.merckmanuals.com/professional/sec19/ch279/ch279m.html
"The overall mortality rate of early-onset sepsis is 3 to 40% (that of early-onset GBS infection is 2 to 30%) and of late-onset sepsis is 2 to 20% (that of late-onset GBS is about 2%). More recent studies have shown lower mortality rates."
Â
--------I was briefly browsing, but I don't think they're separating out premies vs. term neonates here, which would explain the huge range. Prematurity is a secondary risk factor in addition to a positive swab and, as I've said, I personally would take ABTs if I had 2 risk factors (the way it's managed in the UK.)
Â
Â
Interesting, maybe I'm over-analyzing, but this sounds to me like they are saying, 'Um, we're not entirely sure this guideline is the right thing to be 'doing.'
Â
"Continued examination is needed to evaluate the effects of the 2002 guideline revision on early-onset infections and to determine the long-term effects of intrapartum use of antimicrobial agents on neonatal GBS infection."
Â
Came across this in the Mothering article which I find interesting & relevant to this thread:
"Late-onset GBS infection is more complex and has not been convincingly tied to the GBS status of the mother. Late-onset GBS infection in infants occurs between seven days and three months of age."
Â
From that AAFP article linked above:
"The CDC found that the incidence of early-onset GBS infection in 2004 decreased 31 percent from 2000 and 2001, the period just before the universal screening was implemented. The incidence of late-onset GBS infection remained the same from 1996 to 2004."
Â
Interesting. That, to me, might seem to confirm the above statement that late-onset GBS is really unrelated to status of mother and/or intrapartum ABT treatment.
Â
(Incidentally, early-onset GBS dropping only 31% is, IMO, a rather negligible improvement for a treatment with such substantial risks.)
