RESUMO

BACKGROUND AND OBJECTIVES: Early onset sepsis (EOS) in neonates is a scourge that contributes to morbidity and mortality. Prominent stakeholders recommend universal screening of antenatal women for Group B Streptococcus (GBS) and intrapartum antibiotic prophylaxis (IAP) for those who are carriers. However, there are controversies. Other guidelines allow region-specific protocols due to sociodemographic, geographical and ethnic differences. We planned to analyze the prevalence of GBS rectovaginal carriage at 36-37 weeks gestation and its effect on early neonatal status. METHODS: This prospective multidisciplinary study (Obstetrics, Perinatology, Neonatology, Microbiology and Infectious diseases) was conducted in our tertiary care center between February 2020 and May 2021. RESULTS: In our study group which included 966 mothers who delivered at the hospital, 4.8% of mothers who were screened by genito-rectal swabs were positive for GBS at 36-37 weeks gestation. All these mothers were given IAP as per protocol. Other organisms detected on screening mothers were Candida and Gram-negative bacteria. None of the neonates born to these mothers required any intensive care unit admission or therapy for systemic illness. There was no difference in clinically relevant outcomes between neonates who were born to GBS-positive mothers as compared to those born to negative screen result mothers. CONCLUSIONS: GBS prevalence in our cohort was lower than most scientific reports. The neonates born to carrier mothers did not present with signs of early-onset sepsis.

RESUMO

Background: Viridans Group Streptococci (VGS) are a group of distinct species that can cause bacteraemia and other invasive infections. They are also among the common organisms causing infective endocarditis. Data on the epidemiology and clinical profile of VGS is limited, especially from India. Methods: We conducted an electronic medical record-based retrospective analysis of patients with VGS bacteraemia admitted to our hospital between January 2012 to December 2021. Blood cultures were incubated by BacT/ALERT system and bacterial identification and susceptibility testing were done by using the VITEK 2 microbial identification system. Susceptibility test reporting was as per Clinical and Laboratory Standards Institute (CLSI) guidelines. The incidence, clinical profile, source of bacteraemia, co-morbidities and antimicrobial resistance among VGS bacteraemia were analyzed. Results: VGS were isolated in 219 patients, accounting for 3.2% of positive blood cultures during the period studied. The median age of the patients was 58 years and 69% were males. Diabetes mellitus was the most common co-morbidity (55%) followed by chronic kidney disease and chronic liver disease. Patients with haematological malignancy and neutropenia were few. Intra-abdominal infections were the most common source of infection and was noted in 26%. Infective endocarditis was diagnosed in only 10% of the cases. Streptococcus mitis was the most common species isolated followed by S. gallolyticus and S. sanguinis. 9.58% of the isolates could not be identified up to the species level. Overall penicillin susceptibility was 71% and ceftriaxone susceptibility was 92%, with individual species variation. In-hospital mortality was 19%. Conclusions: VGS are an important cause of bacteraemia and was associated with 19% mortality in our study. High rates of penicillin and ceftriaxone resistance are a reason of concern. Molecular diagnostics like matrix assisted laser desorption ionization-time of flight (MALDI-TOF) identification must be increasingly applied for species identification considering that a substantial number of isolates were not identified to species level.
