Cellulitis in patients with chronic lower-limb lymphedema due to HIV-related Kaposi sarcoma.

Chronic Lower Limb Lymphedema (CL-LL) secondary to Kaposi sarcoma (KS) has not been recognized as a risk factor for cellulitis. The aim was to describe the clinical spectrum and use of antimicrobial prophylaxis in patients with cellulitis and CL-LL due to KS. HIV patients with KS, CL-LL, and at least one episode of cellulitis seen at the AIDS Cancer Clinic at INCan in Mexico from 2004 to 2019 were included. Demographic and clinical data were obtained from medical records. Thirty-nine men all with CL-LL were included. Clinical factors associated with cellulitis were groin and/or lymph-node KS infiltration (69.2%), onychomycosis and/or tinea pedis (44.7%), ulcerated lesions (38.4%), and obesity (2.5%). Eighteen (46.1%) were hospitalized in the first episode and eight (20.5%) in recurrence. Six (25.3%) died, two of toxic shock syndrome (TSS), and one of septic shock. Fourteen (35.8%) had at least one recurrent episode of cellulitis. Twenty-five (64.1%) received prophylaxis. Patients without prophylaxis had significantly more unfavorable outcomes (hospitalization and recurrences) than those with prophylaxis. CL-LL due to KS is a risk factor for cellulitis and severe complications in patients with a long life expectancy. Antimicrobial prophylaxis needs to be explored as it could prevent complications.
