Yes, it is necessary to treat Group B strep (Streptococcus agalactiae) urinary tract infections in non-pregnant females. Treatment is recommended when GBS is found in significant quantities in urine (typically ≥10,000 CFU/mL) or when a patient has symptoms of UTI with GBS as the causative organism. The standard treatment is a 5-7 day course of antibiotics, with amoxicillin (500 mg three times daily) being the first-line option due to GBS's consistent sensitivity to penicillins 1. For patients with penicillin allergies, alternatives include cephalexin (500 mg four times daily), nitrofurantoin (100 mg twice daily), or trimethoprim-sulfamethoxazole (160/800 mg twice daily), though resistance patterns should be considered. Fluoroquinolones like ciprofloxacin are generally reserved for complicated cases or when other options aren't suitable. Untreated GBS UTIs can lead to complications such as pyelonephritis, recurrent infections, or rarely, systemic infection. Unlike in pregnant women where GBS colonization alone requires treatment to prevent neonatal transmission, in non-pregnant women, treatment is based on the presence of actual infection rather than mere colonization. Some studies suggest that non-antibiotic treatments, such as non-steroidal anti-inflammatory drugs (NSAIDs), may be beneficial in reducing symptoms, but they are not a replacement for antibiotic therapy in cases of confirmed GBS UTI 2. It's essential to note that the management of UTIs, including those caused by GBS, should be guided by the most recent clinical guidelines and the patient's specific clinical presentation. Given the potential for complications and the importance of appropriate antibiotic use, treatment decisions should be made on a case-by-case basis, considering factors such as the severity of symptoms, the presence of underlying medical conditions, and local resistance patterns. In general, the approach to treating UTIs in non-pregnant women emphasizes the use of antibiotics when the infection is confirmed, with the choice of antibiotic depending on factors like susceptibility patterns and patient tolerance 3, 4, 5.
