Moving Past the Routine Use of Macrolides —Reviewing the Role of Combination Therapy in Community-Acquired Pneumonia

AbstractPurpose of ReviewDespite advances in diagnostic microbiology and sepsis management, community-acquired pneumonia (CAP) remains a significant cause of morbidity and mortality. Current recommendations regarding the use of beta-lactams in combination with macrolides published in clinical practice guidelines are variable and based on low-quality evidence that is frequently retrospective, observational, and heterogeneous in nature. While population-based studies have historically suggested improved clinical outcomes with the routine use of macrolide combination therapy in hospitalized patients with CAP, emerging evidence from recent randomized controlled trials has challenged this practice. In this article, we discuss the historical rationale and current evidence for combination macrolide therapy in the management of CAP.Recent FindingsRecent randomized controlled trials have assessed the non-inferiority of beta-lactam monotherapy compared to beta-lactam/macrolide combination therapy in adult patients hospitalized with CAP. Beta-lactam monotherapy was associated with equivalent clinical outcomes in patients with mild to moderate CAP. Patients with severe CAP managed with beta-lactam monotherapy have demonstrated worse clinical outcomes when compared to patients treated with combination therapy. In addition, previous beta-lactam exposure prior to hospitalization has not been shown to negatively impact outcomes in patients managed with beta-lactam monotherapy in the hospital...
