Recurrent Erysipelas: Clinical Challenges and Strategies for Prevention-A Narrative Literature Review.

Recurrent erysipelas is a common and clinically significant condition that poses challenges for both patients and healthcare systems. Each episode may damage lymphatic vessels, leading to chronic lymphedema, which perpetuates the risk of further relapses. Recurrence rates remain high, ranging from 11% in outpatients during the first year to up to 46% of hospitalized patients within three years. The lower limbs are the most frequent site, although recurrences may also occur in other regions, such as the upper limb after mastectomy with lymph node dissection. This review summarizes current knowledge on risk factors, preventive measures, and chemoprophylaxis in recurrent erysipelas. Modifiable risk factors such as obesity, diabetes, venous insufficiency, tinea pedis, and poor hygiene play an important role, while non-modifiable factors include age, sex, and a history of prior episodes. Non-pharmacological strategies-weight reduction, glycemic control, smoking cessation, compression therapy, and meticulous skin care-form the cornerstone of prevention and may reduce the need for long-term antibiotics. Antibiotic prophylaxis, most commonly with oral penicillin V or intramuscular benzathine penicillin, has been shown to lower recurrence rates. However, efficacy may be reduced in patients with chronic edema or severe obesity. Macrolides serve as alternatives in penicillin-allergic patients, but concerns remain about resistance, adverse effects, and drug-drug interactions. In conclusion, recurrent erysipelas requires a multifaceted approach. While antibiotic prophylaxis is effective, its long-term success depends on simultaneous management of underlying conditions. Further studies are needed to define optimal regimens, treatment duration, and non-antibiotic alternatives.
