    Wegener Granulomatosis Complicated by Brain Abscess Caused by Nocardia spp.
    (2016) Sahin, Sevgi; Balcan, Baran; Kiziltas, Safak; Aydin, Mehtap; Y-1366-2018; A-4721-2018
    Wegener granulomatosis is a multisystemic disease associated with high mortality rate and characterized by necrotizing granulomatous vasculitis predominantly in the respiratory tract and kidneys. Presence of kidney failure at the time of diagnosis describes a poor prognostic marker. We presented a Wegener granulomatosis case complicated with brain abscess caused by Nocardia.

    The Distribution and Antimicrobial Susceptibility Profiles of Etiologic Agents Isolated From Bacteremia Episodes Among Immunocompromised Patients
    (2017) Demirkaya, Melike Hamiyet; Yesilkaya, Aysegul; Akcil-Ok, Mehtap; Kurt-Azap, Ozlem; 0000-0002-3171-8926; AAK-4089-2021
    Objective: Bacteremia is the leading cause of morbidity and mortality among immunocompromised patients. The aim of this study is to evaluate the etiology of bacteremia and the antibiotic susceptibilities of etiologic agents among immunocompromised patients followed up from January 1, 2012 to July 30, 2013. Methods: Immunocompromised patients, both inpatient and outpatient treated in our hospital, were followed prospectively. The definition of "immunocompromised patients" consisted of solid organ (kidney, liver) transplantation recipients and hemato-oncologic malignancy patients with a history of chemotherapy in the previous month before bacteremia. Results: This prospective study comprised of 167 bacteremia episodes of 130 consecutive immunocompromised patients. The most isolated group of bacteria was Gram-negative bacteria. Escherichia coli was the most commonly (30.8%) isolated bacteria and the second was coagulase-negative staphylococci (15.1%). Fifty one percent of the E. coli isolates were extended-spectrum beta-lactamasepositive. Acinetobacter baumannii was the second most common bacteria of Gram-negative agents and the ratio of multiple drug-resistant (MDR) isolates among Acinetobacter isolates was 73%. Conclusions: Gram-negative bacteria are the most common causative agents of bacteremia in immunocompromised patients in our hospital. The rising ratio of MDR A. baumannii is a striking problem which causes difficult-to-treat infections.

    Renal transplantasyon hastalarında kaposi sarkomu: klinik özellikler ve insan herpes virüsü-8'in varlığı
    (Türkderm ,39 ,4 ,249-253, 2005) Saray, Yasemin; Seçkin, Deniz; Butros, Reha; Haberal, Mehmet
    Renal transplantasyon hastalarında Kaposi sarkomu sıklığı artmıştır. Bu çalışmada, renal transplantasyon hastalarında gelişen Kaposi sarkomunun prevelansı, klinik özellikleri ile insan herpesvirusu-8'in etyolojideki rolü araştırıldı. Kaposi sarkomu tanısı alan renal transplantasyon hastalanın dosyaları incelendi. Altı hastada lezyonlu deride insan herpesvirusu-8 DNA'sı araştırıldı. Kaposi sarkomu prevelansı %1.2 idi. Mukokütanöz tutulum %76.9'unda, viseral tutulum %61.5'inde saptanmıştı. Tedavi ile hastaların %61.5'inde remisyon, %23.1'inde parsiyel remisyon izlenmişti. Viseral tutulum olanların %25'i ölümle sonuçlanmıştı. Altı hastanın tümünde virusa ait DNA saptandı. Renal transplantasyon hastalarında gelişen Kaposi sarkomunda viseral tutulum sıktır ve mortaliteyi arttırır. Etyopatogenezde, immünosüpresyon ile birlikte insan herpesvirusu-8 rol oynamaktadır. Background and Design: The frequency of Kaposi's sarcoma is increased in renal transplantation patients. The prevalence, clinical features and the etiopathological role of human herpesvirus-8 in Kaposi's sarcoma in renal transplantation patients were investigated in this study. Patients and Methods: Files of renal transplantation patients who were diagnosed as Kaposi's sarcoma have been examined. Human herpesvirus-8 DNA was investigated in the lesional skin of 6 patients. Results: The prevalence of Kaposi's sarcoma was 1.2%. Mucocutaneous and visceral involvement was noted in 76.9% and 61.5% of the patients, respectively. In 61.5% of the patients total remission, in 23.1% partial remission was observed. Twent-five percen[ of the patients with visceral involvement were died. Viral DNA was detected in all of the 6 patients. Conclusion: Visceral involvement is common in Kaposi's sarcoma developing in renal transplant recipients and increases the mortality. Immunosuppresion with human herpesvirus-8 play roles in etiopathogenesis
