There are no symptoms that reliably predict the presence of bacteria in children with conjunctivitis. Most kids with conjunctivitis get better with or without antibiotics, even if bacteria are present.
Synopsis
This study investigates the etiology and outcomes of acute infectious conjunctivitis in children, emphasizing the role of Haemophilus influenzae as the primary bacterial pathogen associated with conjunctivitis cases, as shown through polymerase chain reaction (PCR) analysis. In this multicenter study of 194 cases and 196 controls, H. influenzae was the only microorganism significantly linked to conjunctivitis. Despite frequent antibiotic use, resolution rates by day five were high regardless of treatment, highlighting the self-limiting nature of the condition and the limited efficacy of antibiotics, which were associated with adverse events in 20% of cases.

More isn’t always more
This case-control study adds to a growing evidence about pediatric conjunctivitis and the ongoing debate of viral vs. bacterial. Here, the authors looked at differences in pathogens, symptoms, and disease course in children with conjunctivitis vs. healthy controls and controls with URI but without any conjunctival symptoms. The only significant bacteria isolated in conjunctivitis was H. Influenzae, although it was also isolated in some healthy controls. Currently, many clinicians practice using symptoms to differentiate between bacterial and viral conjunctivitis, and thus the need for antibiotics; however, there were no symptoms found in this study that reliably predicted the presence of bacteria, calling this practice into question. That said, the authors did not consider the relevance of unilateral vs. bilateral symptoms, something which is frequently considered in the clinical setting. Unsurprisingly, this study further emphasizes prior work on the need for judicious antibiotic prescription not only for antibiotic stewardship purposes, but also to avoid harmful side effects. Notably, this was not a randomized controlled trial, so these results should be interpreted with some caution. Personally, I’ll be even more likely to recommend observation without antibiotics, especially after seeing that rate of complications from antibiotic therapy. Finally, the study only included children 6 months to 17 years; thus, findings cannot be applied to younger infants.
