“…Most of our patients had a secondary source of bacteremia, and the most common source of that was SSTI, which accounted for 48% of the cases, followed by primary bacteremia in 20% and UTI in 12%. These percentages were similar to those in a study of 126 patients in the United States that noted primary bacteremia accounted for 12.9% of cases [13]. The same study reported a mortality rate of 13.4% due to invasive GBS bacteremia [13], which was somewhat lower than the 90-day mortality rate of 22% in our patients.…”

Background Invasive disease due to group B Streptococcus (GBS) infection in adult males and nonpregnant females can cause various diseases, such as primary bacteremia, endocarditis, skin and soft tissue infection (SSTI), and meningitis. Especially in older people, invasive GBS infection has a high case fatality rate. In Saudi Arabia, little is known about the clinical signs and symptoms of GBS bacteremia and the associated risk factors and mortality rate. Methodology We performed a retrospective study at King Abdulaziz University Hospital in Jeddah, Saudi Arabia, a large tertiary hospital, to investigate clinical disease, potential risk factors, susceptibility patterns, and mortality related to GBS in adult males and nonpregnant females diagnosed with GBS bacteremia. All patients ≥14 years of age with GBS-positive blood cultures from January 1, 2015, until December 31, 2022, were included. Patient data such as age, sex, comorbidities, hospital ward, length of hospital stay, monomicrobial versus polymicrobial bloodstream infection, antimicrobials used for treatment, complications, whether an infectious disease specialist had seen them, and outcomes were extracted from the electronic health records. Results A total of 50 patients with GBS bacteremia met the inclusion criteria. The mean age of these patients was 57.0 years (SD = 16.0), and 27 (54%) were female. The 90-day mortality was 11 (22%). In total, 34 (68%) patients had a monomicrobial infection, and among those with polymicrobial infection, methicillin-resistant Staphylococcus aureus was the most common co-infection (56%, n = 9/16). The most common source of infection was SSTI and wound infection in 24 (48%) patients. Most patients had one or more comorbidities; the mean Charlson comorbidity index was 3.8 (SD = 2.4). The most prevalent comorbidity was diabetes mellitus in 35 (70%) patients. Of all variables analyzed, only age was significantly associated with mortality (p = 0.016), and age had a predictive value for mortality (p = 0.035). Conclusions In Saudi Arabia, as in other countries, GBS is an important pathogen, especially in older people, that should be considered when encountering a patient with bacteremia. In addition, in patients over 65 years old, GBS bacteremia carries a high risk for mortality.

“…Skoff et al ( 1 ) suggest that the increasing prevalence of chronic medical conditions might explain the increasing incidence of GBS disease among adults. Most patients in our cohort had underlying conditions, as has been noted previously ( 1 , 17 – 19 ). Skin/soft tissue infections were present in 43%, and the presentation was nonfocal for 16%, usually in patients with hepatic disease ( 1 , 2 ).…”
