    Rhinomaxillary Mucormycosis in a Renal Transplant Recipient: Case Report
    (Başkent Üniversitesi, 2012-12) Azarpira, Negar; Khademi, Bighan; Kazemi, Kourosh; Ashraf, Mohamd Javad
    Objectives: Rhinomaxillary mucormycosis is a clinical manifestation of zygomycosis in solid-organ transplant recipients. Without proper diagnosis and treatment, rhino-orbital-cerebral zygomycosis, particularly a central nervous system disease, will develop with substantial complications. Case report: A 42-year-old man who had undergone renal transplant was admitted to our otolaryngology department with unilateral bloody nasal discharge. Mucormycosis was detected in the necrotic tissue of the maxillary sinus. Surgical ablation of the infected parts, along with antifungal treatment, restricted extension of the infection. Conclusions: Early detection of opportunistic infections in transplant recipients plays an important role in preventing dissemination. Fungal infections, including zygomycosis, should be considered in all solid-organ recipients, especially in persons with local unusual manifestations. Early diagnosis and successful treatment reduce mortality.

    Procalcitonin and C-reactive Protein Serum Levels After Hematopoietic Stem-Cell Transplant
    (Başkent Üniversitesi, 2009-06) Azarpira, Negar; Daraie, Masumeh; Aghdaie, Mahdokht; Ramzi, Mani
    Objectives: Hematopoietic stem-cell transplant is a curative therapy for several malignant and nonmalignant disorders. The purpose of this study was to investigate the association of serum levels of high-sensitivity C-reactive protein and procalcitonin with complications such as acute graft-versus-host disease, veno-occlusive disease, and infection after hematopoietic stem-cell trans­plant. Materials and Methods: Serum high-sensitivity C-reactive protein and procalcitonin levels were sequentially measured with an enzyme-linked immunosorbent assay and a semiquantitative immunochromatographic assay in 35 patients who had undergone hematopoietic stem-cell trans­plant. Results: The high-sensitivity C-reactive protein serum level was increased in patients with acute graft-versus-host disease and in those with sepsis. Increased procalcitonin levels were associated only with bacterial infection. Only procalcitonin levels differentiated patients with infection from those with another transplant-related complication. Veno-occlusive disease did not alter C-reactive protein or procalcitonin levels. Conclusions: Our results support theories that serum levels of high-sensitivity C-reactive protein and procalcitonin are biomarkers for transplant-related complications such as graft-versus-host disease or infection and that the procalcitonin level can differentiate patients with infection from those with graft-versus-host disease.
