Predictors of primary breast abscesses and recurrence

Area of Science:

• Medical research
• Infectious diseases
• Surgical pathology

Background:

• Investigated patient and microbiological risk factors for primary breast abscesses and recurrence.
• Identified risk factors predisposing to breast abscess development and subsequent infections.

Purpose of the Study:

• To identify patient and microbiological risk factors for primary breast abscesses.
• To determine factors associated with recurrent breast abscesses.

Main Methods:

• Retrospective review of 89 patients with primary breast abscesses requiring surgical therapy (2000-2006).
• Defined recurrent breast abscess as repeated drainage within 6 months.
• Compared patient characteristics to the general population and between recurrent and non-recurrent groups.

Main Results:

• Nonlactational abscesses had a 57% recurrence rate, compared to 0% for lactational abscesses.
• Patients with primary breast abscesses were predominantly African American (64%), obese (43%), and smokers (45%).
• Tobacco smoking was the only significant factor associated with recurrence (P=0.003); recurrent cases showed higher rates of mixed bacteria, anaerobes, and Proteus, with lower rates of Staphylococcus.

Conclusions:

• African American race, obesity, and tobacco smoking are risk factors for primary breast abscesses.
• Smokers with mixed bacterial and anaerobic infections are more likely to experience recurrent breast abscesses.
• Broader antibiotic coverage is recommended for high-risk groups.
