“…RCOG recommend cephalosporin use in mild penicillin allergy, and vancomycin in severe penicillin allergy [9]. ACOG advice differs slightly from this in the management of severe penicillin allergy; they recommend clindamycin, but only if the GBS isolate is known to be susceptible to clindamycin; otherwise, vancomycin is recommended [13].

“…A review of GBS policies worldwide showed that the majority (63%) of countries surveyed had an IAP policy, over half (58%) used microbiological screening, and many (42%) used a clinical risk-factor-based policy [11]. In the USA, the Center for Disease Control (CDC), American College of Obstetricians and Gynaecologists (ACOG) and American Society for Microbiology (ASM) recommend universal antenatal screening, comprising culture testing for GBS at 36-38 weeks and providing IAP for those who are positive, in addition to the use of IAP because of GBS bacteriuria in the current pregnancy or a history of previous GBS-infected neonate [8,12,13]. This approach is also recommended by the Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) [14] and has been implemented by several European countries, including France [15].…”

Background: Early onset group B streptococcal (GBS) disease can cause significant neonatal morbidity and mortality. There is currently no Irish national guideline for GBS screening, and protocols vary across maternity units. Polymerase chain reaction (PCR) testing at induction or labour onset informs triage for antibiotic prophylaxis; however, there are human and infrastructural resource requirements to enable widespread implementation. Aim: Our aim was to identify current standard practices for GBS prevention in Irish obstetric and neonatal services and to utilise this data to inform the need for, and potential impact of implementation of, a national guideline. Methods: A questionnaire on GBS screening, management and existing resources was completed by an informed staff member from each of the 19 Irish maternity units, including questions regarding timing and method of screening, antibiotic usage, and neonatal management. Results: One unit (5.2%) performs routine GBS screening at 35–37 weeks of gestation. Twelve units (63%) screen for GBS following spontaneous rupture of membranes (SROM) after 37 weeks, of which two (17%) perform PCR and ten (83%) culture testing. Seventeen units (89.3%) have access to a GeneXpert PCR machine, and of these, two (11.7%) use the machine for rapid GBS testing. Two units screen patients for GBS at either the start of labour or induction of labour. Four units (21%) use the neonatal early onset sepsis (EOS) calculator. Sixteen units (84%) do not treat asymptomatic infants born to GBS-positive mothers. Conclusion: There is a lack of consistency in the methods for GBS screening and disease prevention across the country, highlighting the need for a national guideline accompanied by an implementation plan and budget to standardise care.

Background Group B streptococcus (GBS) is a leading cause of morbidity and mortality in newborns. Maternal GBS colonization rates vary depending on geographic area, ethnic and social conditions worldwide. Many studies suggested the continuous surveillance of GBS to provide data to guide decision-making and planning prevention and control strategies. Here, we report the rate and the antimicrobial susceptibility pattern of GBS from Vietnamese pregnant women over 5 year period. Methods We worked with 3863 Vietnamese pregnant women at < 37 weeks of gestation at the National Hospital of Obstetrics and Gynecology, Hanoi, Vietnam from Jan 2016 to Dec 2020. The data were recorded and retrieved from the computerized laboratory database. GBS was identified according to the American Society for Microbiology’s guidelines. Antimicrobial susceptibility was tested by the VITEK 2 system or E-test strips. The results were calculated according to the MIC breakpoints recommended by the Clinical and Laboratory Standards Institute. Results The positivity for GBS was 8.02% (310/3863) and the highest resistance rate was to tetracycline 89.66% (234/261), followed by 76.23% (202/265) for erythromycin, 58.21% (156/268) for clindamycin. The multidrug-resistance rate was 59.19% (161/272), and 8.46% (23/272) of isolates were resistant to 6 to 7 of the 12 antibiotics. Resistance to clindamycin in the absence of erythromycin resistance was found in 6/272 (2.2%) samples. The resistance rate to clindamycin was significantly increased (p < 0.01) over the time study period. Nevertheless, all isolates were sensitive to penicillin, ampicillin, ceftriaxone, cefotaxime, quinupristin/dalfopristin, and vancomycin. Conclusion Our results indicate that penicillin and ampicillin are currently the drugs of choice for the prevention and treatment of GBS-related diseases for Vietnamese pregnant women. However, antibiotic resistance to erythromycin and clindamycin was high. Thus, it reinforces the need for continuous surveillance of GBS to provide data to guide planning prevention and control strategies.
