Antibiotic therapy remains a cornerstone of treatment of both medical and surgical presentations of necrotizing enterocolitis (NEC). However, guidelines regarding the administration of antibiotics for the treatment of NEC are lacking and practices vary amongst clinicians. Although the pathogenesis of NEC is unknown, there is consensus that the infant gastrointestinal microbiome contributes to the disease. The presumed connection between dysbiosis and NEC has prompted some to study whether early prophylactic enteral antibiotics can prevent NEC. Yet others have taken an opposing approach, studying whether perinatal antibiotic exposure increases the risk of NEC by inducing a state of dysbiosis. This narrative review summarizes what is known about antibiotics and their association with the infant microbiome and NEC, current antibiotic prescribing practices for infants with medical and surgical NEC, as well as potential strategies to further optimize the use of antibiotics in this population of infants.

Antibiotics are first-line therapy for pouch inflammation, increasing the potential for gut colonization with multi-drug resistant organisms (MDRO). Fecal microbial transplant (FMT) is being studied in the treatment of pouchitis and in the eradication of MDRO.

Objectives: Considering the importance of patient-centered care, we aimed to evaluate the impact of systemic antibiotics on oral health-related quality of life during nonsurgical periodontal treatment. This controlled trial addresses a gap in understanding how systemic antibiotics influence patient-reported outcomes, focusing on Stage III periodontitis.

Materials And Methods: Sixty-one adults participated in a double-blind, randomized clinical trial, with participants divided into two groups: the test group, which received antibiotics, and the control group.
