Abstract Background Methicillin-resistant Staphylococcus aureus (MRSA) causes >70,000 invasive infections annually in the United States, and recurrent infections pose a major clinical challenge. We examined risk factors for recurrent MRSA infections. Methods We identified patients with an initial invasive MRSA infection (isolation from a normally sterile body site) from 2006 to 2013, through active, population-based surveillance in selected counties in nine states through the Emerging Infections Program. Recurrence was defined as invasive MRSA isolation >30 days after initial isolation. We used logistic regression with backwards selection to evaluate adjusted odds ratios (aOR) associated with recurrence within 180 days, prior healthcare exposures, and initial infection type, controlling for patient demographics and comorbidities. Results Among 24,478 patients with invasive MRSA, 3,976 (16%) experienced a recurrence, including 61% (2,438) within 180 days. Risk factors for recurrence were: injection drug use (IDU) (aOR; 1.38, 95% confidence interval [CI]: 1.15–1.65), central venous catheters (aOR; 1.35, 95% CI: 1.22–1.51), dialysis (aOR; 2.00, 95% CI: 1.74–2.31), and history of MRSA colonization (aOR; 1.35, 95% CI: 1.22–1.51) (figure). Recurrence was more likely for bloodstream infections (BSI) without another infection (aOR; 2.08, 95% CI: 1.74–2.48), endocarditis (aOR; 1.46, 95% CI: 1.16–1.55), and bone/joint infections (aOR; 1.38, 95% CI: 1.20–1.59), and less likely for pneumonia (aOR: 0.75, 95% CI: 0.64–0.89), compared with other initial infection types. When assessed separately, the presence of a secondary BSI with another infection increased the odds of recurrence over that infection without a BSI (aOR: 1.96, 95% CI: 1.68–2.30). Conclusion Approximately one in six persons with invasive MRSA infection had recurrence. We identified potential opportunities to prevent recurrence through infection control (e.g., management and early removal of central catheters). Other possible areas for preventing recurrence include improving the management of patients with BSI and bone/joint infections (including both during and after antibiotic treatment) and mitigating risk of infection from IDU.

Community-acquired (CA) methicillin-resistant Staphylococcus aureus (MRSA) rates have rapidly increased in the general population; however, little data on recent incidence rates and risk factors of CA-MRSA infections among HIV patients appear in the literature. A retrospective study was conducted from 1993 through 2005 among patients at a large HIV clinic. Trends in CA-MRSA infection incidence rates, clinical characteristics and risk factors for CA-MRSA were evaluated. Seven percent of our cohort developed a CA-MRSA infection during the study period. The rate of CA-MRSA infections among HIV-infected population significantly increased since 2003, with an incidence of 40.3 cases/1000 person-years in 2005, which was 18-fold higher than the general population served at our facility. In all, 90% of infections were skin/soft tissue infections with a predilection for buttock or scrotal abscess formation; 21% of patients experienced a recurrent infection. Risk factors included a low CD4 count at the time of infection (odds ratio [OR] per 100 CD4 cells 0.84, P = 0.03), high maximum log10 HIV viral load (OR 4.54, P<0.001), recent use of β-lactam antibiotics (OR 6.0 for receipt of two prescriptions, P<0.001) and a history of syphilis (OR 4.55, P = 0.01). No patient receiving trimethoprim-sulfamethoxazole prophylaxis developed a CA-MRSA infection. Over the study period, CA-MRSA accounted for an increasing percentage of positive wound cultures and Staphylococcus aureus isolates, 37% and 65%, respectively, during 2005. In conclusion, CA-MRSA infections have rapidly increased among HIV-infected patients, a group which has a higher rate of these infections than the general population. Risk factors for CA-MRSA among HIV-infected patients include low current CD4 cell count, recent β-lactam antibiotic use and potentially high-risk sexual activity as demonstrated by a history of syphilis infection.
