Successful Treatment of Saksenaea sp. Osteomyelitis by Conservative Surgery and Intradiaphyseal Incorporation of Amphotericin B Cement Beads
International audienceOsteoarticular mucormycosis cases are quite rare and challenging infections that are mostly due to direct inoculation during traumatic injury among immu-nocompetent patients. Classic management includes a combination of aggressive surgical debridement, which may lead to amputation, and long-term systemic lipo-somal amphotericin B therapy. This article describes the successful treatment of Sak-senaea sp. osteomyelitis in a patient with diabetes mellitus, using a combination of systemic antifungal therapy and conservative surgery with insertion of amphotericin-impregnated cement beads. KEYWORDS Mucorales, amphotericin B, antifungal agents, osteomyelitis M ucorales osteomyelitis still presents diagnostic and therapeutic challenges and is associated with high mortality rates despite a combined therapeutic strategy involving antifungal treatment and surgery (1). Members of the order Mucorales are present in soil and plant debris and could be responsible for osteoarticular mucormy-cosis as a consequence of contamination through disrupted cutaneous barriers after traumatic injury (2). Surgical management is classically aggressive and complicated, with poor functional outcomes or even amputation. We report the first successful conservative orthopedic treatment of Saksenaea sp. osteomyelitis in a patient with diabetes mellitus, using in situ amphotericin-impregnated cement beads in combination with systemic posaconazole therapy. A 63-year-old man was admitted for a painful and swollen right ankle. He had well-controlled diabetes mellitus, hypertension, and degenerative arthritis. He lived in France and had never travelled overseas. Seven years earlier, he had suffered ankle trauma due to a rockfall and developed a necrotic subcutaneous abscess and a diaphyseal periosteal reaction seen on X-ray films. He underwent surgical drainage of the abscess; the sample cultures remained sterile and the surgical wound outcome was marked by a purple painless cutaneous infiltration. Seven years after the first operation, the patient's ankle became painful again and a bone biopsy was performed, which revealed no microorganisms in cultures. Empirical broad-spectrum antibiotherapy was initiated, without efficacy. Lower leg pain, erythema, and edema worsened and a satellite, 4-cm, right inguinal area of lymphadenopathy appeared. The patient was afebrile and had moderate biological inflammatory syndrome (C-reactive protein level, 50 mg/liter). Magnetic resonance imaging (MRI) showed decreased signal intensity on Citation Parize P, Mamez A-C, Garcia-Hermoso D, Dumaine V, Poirée S, Kauffmann-Lacroix C, Jullien V, Lortholary O, Lanternier F. 2019.

Last Generation Triazoles for Imported Eumycetoma in Eleven Consecutive Adults
the French Mycosis Study GroupInternational audienceBackground: Optimal management of eumycetoma, a severely debilitating chronic progressive fungal infection of skin, disseminating to bone and viscera, remains challenging. Especially, optimal antifungal treatment and duration are ill defined.Methodology/Principal Findings: We conducted a monocentric retrospective study of 11 imported cases of eumycetoma treated by voriconazole or posaconazole for at least 6 months. Response to treatment was assessed through evolution of clinical and magnetic resonance imaging (MRI). (1→3) ß-D-glucan (BG) and positron emission tomography using [18F] fluorodeoxyglucose (PET/CT) results were also assessed. Identified species were Fusarium solani complex (n = 3); Madurella mycetomatis, (n = 3), and Exophiala jeanselmei, (n = 1). Moreover, two coelomycetes and one phaeohyphomycetes strains without species identification were retrieved. Serum BG and PET/CT were abnormal in 7/8 and 6/6 patients tested, respectively. Patients received last generation azoles for a mean duration of 25.9±18 months. Complete response (major clinical and MRI improvement) was observed in 5/11 patients, partial response (minor MRI improvement or stable MRI findings) in 5 and failure (MRI evidence of disease progression) in one, with a 73±39 [6–132] months mean follow-up. Relapse occurred in 2 patients after treatment discontinuation. Optimal outcome was associated with fungal species, initiation of last generation triazole therapy (<65 months since first symptoms), negative serum BG and PET/CT normalization.Conclusions/Significance: MRI, PET/CT and serum BG appear as promising tools to assess optimal time of antifungal treatment for eumycetoma
