We report a case of implantable cardioverter-defibrillator infection due to Scedosporium apiospermum. This infection persisted despite systemic antifungal treatment with voriconazole and was controlled after removal of the foreign device and replacement of the involved tricuspid valve. This case underscores the importance of a combined surgical and medical approach for this complicated infection. Scedosporium species should be considered in the differential diagnosis of cardiac or intravascular device-related infections. 相似文献

Infection of Scedosporium apiospermum is very rare but is now emerging as an important cause of both localized and disseminated infections in immunocompromised patients. A 62-year-old woman, who had undergone steroid therapy for refractory idiopathic thrombocytopenic purpura and had a history of diffuse large B cell lymphoma, developed a deep skin ulcer complicated with lymphangitis. After culture study demonstrated the presence of S. apiospermum, voriconazole (VRCZ) was administered and prompt improvement was observed. Because it is difficult to distinguish S. apiospermum from Aspergillus by histopathology and S. apiospermum is resistant to amphotericin B, VRCZ should be selected as the first choice of antifungal agent when mold is considered to be the causative organism. 相似文献

Abstract: Transplant recipients receive a number of immunosuppressive medications that result in an increased risk of infection, including infections with microbes that are normally not pathogenic. We describe a patient with end-stage renal disease who underwent kidney transplantation. Six months postoperatively, he presented with a lesion on his ankle, multiple thigh nodules, and right testicular pain. Biopsy of the ankle lesion demonstrated Pseudallescheria boydii ( Scedosporium apiospermum ), a common environmental fungus. Following orchiectomy, multiple fungal elements were found that were initially described as Aspergillus species, but later identified as P. boydii . In addition, multiple brain abscesses were found on magnetic resonance imaging. Despite treatment with multiple antifungal medications, the patient died of cardiac dysrhythmia. Current diagnostic and therapeutic alternatives for P. boydii are reviewed. 相似文献

Scedosporium apiospermum is a widely distributed fungus that can be found in the soil, manure and decaying vegetation. Human infection with this fungus is facilited by immunodepression. A 65-year-old man, who was taking oral methylprednisolone for rheumatoid polyarthritis had for a few months ulcerated or suppurative nodules whose incision discharged a thick honey-colored exudate. An ulceration over the first right metatarsophalangian articulation had left the bone exposed. The treatment for Pseudomonas aeruginosa, initially isolated in the exudate was unsuccessful. Other microbiology samples exhibited Scedosporium apiospermum, without bacteria. The pathogenic nature of the infection was proven on a skin and bone (head of the first metatarsian) biopsy showing numerous branching and septate hyphae. The patient was successfully treated by itraconazole. Scedosporium apiospermum is the cause of a growing number of human infections due to widespread use of immunosuppressors. Skin and lung localizations predominate. Osteoarticular infection is relatively rare, which contributes to the originality of this observation. Treatment is not well defined and essentially combines surgical drainage with antifungals like itraconazole. This emergent fungal infection, which has non specific clinical manifestations, must be considered in immunocompromised patients. 相似文献

We present a case of cerebral Scedosporium apiospermum infection presenting with intestinal manifestations in a 64-year-old male patient on immunosuppression for orthotopic liver transplantation. At admission, the patient’s chief complaint was chronic watery diarrhea and he was found to have colonic ulcers on endoscopy. His hospital course was complicated by a tonic–clonic seizure caused by a left frontal brain abscess, with the causative agent being identified by culture. He was treated with lobectomy, high-dose intravenous voriconazole, and liposomal amphotericin with clinical, endoscopic, and histologic improvement. To our knowledge, S. apiospermum has not been previously described as a cause of colitis. The septate branching appearance of the Scedosporium species is similar to the more common Aspergillus species. This case of gastrointestinal Scedosporium brings into question previously reported cases of isolated gastrointestinal aspergillosis diagnosed by histopathology. Clinical suspicion for S. apiospermum must be maintained in immunosuppressed patients presenting with neurologic and gastrointestinal symptoms. 相似文献

A disseminated Scedosporium apiospermum infection was diagnosed in a woman with severe asthma and treated with corticosteroids. This fungi is resistant to fluconazole and amphotericin B. The infection was refractory to itraconazole, but responded successfully to voriconazole. A review of the literature is provided. 相似文献

A 69-year-old man treated with corticosteroids and immunosuppressive agents for acutely exacerbated interstitial pneumonia was found to have an ingrown nail in the left big toe and that suppurated despite treatment by dermatologists. Culture of the pus expressed from the toe yielded Scedosporium apiospermum. The patient suffered liver dysfunction a few days later when treated with intravenous voriconazole (VRCZ), which was discontinued due to the high plasma VRCZ concentration. Discrete erythema and subcutaneous nodules developed in left leg 2 or 3 weeks later. Ultrasonography showed tubular structures with substantial echoes that were not connected to veins in the subcutaneous tissue of the left leg. These findings suggested a nodular lymphangitic pattern of spreading of S. apiospermum soft tissue infection. Oral VRCZ at 100 mg/day was started, and increased to 200 mg/day after the plasma VRCZ concentration was measured. VRCZ was stopped after about 2 months, by which time the man had fully recovered. Because VRCZ-induced liver dysfunction was reported significantly associated with plasma level, we treated this case safely by administering VRCZ while measuring the plasma concentration. 相似文献

A case of lymphadenitis caused by Scedosporium apiospermum in a 25-year-old immunocompetent woman had been misdiagnosed as tuberculous lymphadenitis. Clinical response to itraconazole therapy was obtained in 6 months; to our knowledge, this is the first report of lymphadenitis caused by S. apiospermum in humans. 相似文献

Four cases of respiratory tract intracavitary colonization (fungus ball) due to Scedosporium apiospermum (teleomorph, Pseudallescheria boydii) are reported. The need for a careful search for anneloconidia, in order to establish the etiologic diagnosis in the clinical specimen by microscopy, is emphasized. 相似文献

Scedosporium apiospermum fungemia in a lung transplant recipient 总被引:1,自引:0,他引:1
Scedosporium apiospermum, the asexual anamorph of the cosmopolitan fungus Pseudallescheria boydii, is emerging as an important cause of disseminated infection in immunocompromised patients. We present our experience with the first reported case of S apiospermum fungemia in a lung transplant patient. Disseminated infection resulted in sepsis, multiorgan failure, and death. Review of the literature highlights the diagnostic difficulties related to the similarities between S. apiospermum and Aspergillus sp. This superficial resemblance has a significant impact on clinical outcomes considering the inherent resistance of Scedosporium to amphotericin B, the traditional antifungal of choice for disseminated hyalohyphomycoses. 相似文献

We report two cases of nasosinusal infection caused by Scedosporium apiospermum and involving the nasal fossa in one case and the maxillary sinus in the other. The course of the disease varied according to the patient's immune status. The otherwise healthy patient (case n. 1) was completely cured by surgery, whereas the immunosuppressed patient (case n. 2) had local extension with pseudotumoral symptoms and lysis of the inter-sinusonasal septum; an early surgical treatment combined with local administration of a specific antifungal agent resulted in an apparent cure, but the patient died a few months later. A review of the literature confirms the invasive potential of this fungus which in immunosuppressed patients (by therapeutic immunosuppressants or by a debilitating disease) becomes a dangerous opportunistic organism. Cultures on Sabouraud's medium provide an accurate diagnosis and enable antifungal drugs to be tested, miconazole being the most regularly effective of them. In healthy subjects surgery is the sole treatment of nasal or sinusal lesions, while in all immunocompromised patients it must be combined with an antifungal treatment. 相似文献
