Item A Novel Therapeutic Approach for Renal Transplant Recipient with Septic Shock and Acute Kidney Injury: A Case Report(2021) Yesiler, Fatma Irem; Yurtsever, Beyza Meltem; Gedik, Ender; Zeyneloglu, Pinar; Haberal, Mehmet; 0000-0002-0612-8481; 0000-0002-4737-7660; 0000-0002-7175-207X; 0000-0002-3462-7632; AAJ-4212-2021; ABI-2971-2020; AAJ-8097-2021Extracorporeal blood purification (EBP) therapies, using oXiris (R) haemofilter, are popular and used globally in intensive care units for management of patients with septic acute kidney injury (AKI). Herein, we present a case of an immunocompromised renal transplant recipient with sepsis and AKI who was treated with continuous renal replacement therapy (CRRT) using oXiris (R) haemofilter. A 45-year-old female who underwent cadaveric renal transplantation in 2015 was admitted due to septic shock secondary to Escherichia coli urinary tract infection (bacteraemia) and acute respiratory distress syndrome (ARDS). Her acute physiology and chronic health assessment score was 23, sepsis-related organ failure score was 11 and Glasgow coma scale was 15. She was intubated because of moderate ARDS and administered vasopressors due to hemodynamic instability. For immunosuppressive therapy, methylprednisolone (40 mg q12h) was administered. Antimicrobial therapies, including intravenous meropenem, linezolid, trimethoprim-sulfamethoxazole, voriconazole and oseltamivir, were administered. She exhibited metabolic acidosis and septic AKI and was classified as Kidney Disease Improving Global Outcomes stage 3. Therefore, CRRT with oXiris (R) haemofilter was administered at the 11th hour after admission. A full recovery of transplant renal function and diuresis was observed 7 days after admission. She was transferred to ward after 9 days and discharged after 2 weeks, without the requirement of RRT. EBP is proposed as an adjuvant therapy for sepsis and AKI. Solid organ transplant recipients with septic AKI may benefit from early usage of oXiris (R) haemofilter with CRRT as a novel approach for improving survival and clinical outcomes.Item Evaluation of extensively drug-resistant gram-negative bacteremia among solid-organ transplant recipients: a multicenter study(2021) Yanik Yalcin, Tugba; Azap, Ozlem; Kose, Adam; Bayindir, Yasar; Saricaoglu, Elif Mukime; Cinar, Gule; Uygun Kizmaz, Yesim; Kursun, Ebru; Aliskan, Hikmet Eda; Tezer Tekce, Yasemin; Eren Kutsoylu, Oya Ozlem; Egeli, Tufan; Ari, Alpay; Albayrak, Yurdagul; Cabadak, Hatice; Deniz, Secil; Demir Onder, Kubra; Kizilates, Filiz; Ozger, Selcuk; Guzel Tunccan, Ozlem; Haberal, Mehmet; 0000-0001-9060-3195; 0000-0002-3462-7632; 33865241; AAE-2282-2021; AAJ-8097-2021Background/aim: The aim of this study is to evaluate the distribution, sources, clinical features, and mortality rates of bacteremia due to evaluation of extensively drug-resistant (XDR) gram negative among solid-organ transplant (SOT) recipients. Materials and methods: A retrospective study of SOT recipients with bacteremia due to XDR gram-negative pathogens in 11 centers between 2016 and 2018 was conducted. Patients' records were evaluated. Results: Of 171 bacteremia that occurred in 164 SOT recipients, 93 (56.7%) were liver, 46 (28%) kidney, 14 (8.5%) heart, and 11 (6.7%) lung recipients. Bacteremia episodes were recorded in the first year in 63.7% of the patients (n = 109), early-onset bacteremia was recorded in 45% (n = 77) of the episodes. In multivariate analysis, catheter-associated bacteremia was an independent risk factor for 7-day mortality (p = 0.037), and early-onset bacteremia was found as an independent risk factor for 30-day mortality (p = 0.017). Conclusion: Difficult-to-treat infections due to XDR bacteria in SOT recipients shadow the success of transplantation. Central venous catheters seem to be the main risk factor. Judicious use of medical devices is of pivotal importance.Item Analysis of Quality of Life, Depression, and Sexual Function in Patients on the Liver Transplant List(2021) Fidan, Cihan; Akdur, Aydincan; Kirnap, Mahir; Selcuk, Haldun; Yildirim, Sedat; Moray, Gokhan; Haberal, Mehmet; 0000-0002-3462-7632; 0000-0002-8726-3369; 34609310; AAJ-8097-2021; AAA-3068-2021Background: I he only treatment in patients developing liver failure is liver transplantation. According to the Ministry of Health, the number of patients waiting for a liver transplantation is 2141, the average waiting period for liver transplantation is approximately 5 years, and 15-18% of these patients lose their life while waiting for transplantation. In these patients, limitations in daily activities and depression-anxiety are commonly found. The aim of this study was to analyze life quality, depression symptoms, and existence of sexual functional disorders of patients waiting for liver transplantation. Methods: A total of 74 patients, who were registered in Baskent University Hospital between 2015 and 2018, were included into the study. Short Form-36, Beck Depression Inventory, and Arizona Sexual Experiences Scale were applied to 56 patients who approved study. Results: Most of the patients were male (64.3%), and the mean age was 46 (18-64). Short Form-36 scores were low in all patients. The mean Beck Depression Inventory score of patients was found as 18.4 +/- 11.3, and they were suffering from moderate depressive symptoms. According to Arizona Sexual Experiences Scale, total mean scores of males was found as 16.3 +/- 5.5, and for females, it was 19.5 +/- 5.3 with a statistically significant difference (P < .05). It was found that sexual dysfunction mostly had moderate to mild. Conclusion: Depression and sexual dysfunction are common in patients with chronic liver diseases, and their life qualities deteriorate significantly. It is anticipated that evaluation of these patients in terms of psychological issues and sexual dysfunction will increase their quality of life during the organ waiting period and affect their well-being post-transplant.Item Vascular Variations and Anastomosis Techniques in Renal Transplant Donors(2015) Haberal, Mehmet; Arer, Ilker Murat; Yabanoglu, Hakan; Caliskan, Kenan; Parlakgumus, Alper; Yildirim, Sedat; Moray, GokhanPurpose: We aimed to share our experience about vascular variations and anastomosis tecniques in renal transplant donors. Material and Methods: 128 donor nephrectomy performed in our hospital between February 2010 and June 2014 were included in our study. Donors were retrospectively analyzed according to age, sex, comorbidity, operation history, site of nephrectomy, vascular variation and anastomosis techniques. Results: 21 (% 16,4) patients have left-sided, 19 (% 14,8) have right-sided and 13 (% 10,2) have bilateral vascular variation. 29 (% 21,2) unilateral double renal artery, 8 (% 6,3) unilateral double renal artery and vein, 4 (% 3,2) unilateral triple renal artery, 3 (% 2,4) early branching renal artery, 2 (% 1,6) unilateral double renal vein and 2 (% 1,6) polar artery are vascular variations observed. of 92 (% 71,9) recepients anastomosis type was end to side between renal artery and external iliac artery and end to side between renal vein and external iliac vein, 32 (% 25) end to end between renal artery and external iliac artery and end to side between renal vein and external iliac vein, 4 (% 3,1) end to side between renal artery and external iliac artery and end to side between renal vein and external iliac vein and end to side between 2nd renal artery and external iliac artery. Conclusion: Preoperative evaluation of renal vasculature of transplant donors is an important issue in means of decreasing peroperative vascular complications and decision for nephrectomy site.Item Mucormycosis with Orbital Apex Syndrome in a Renal Transplant Recipient(2015) Haberal, Mehmet; Kursun, Ebru; Turunc, Tuba; Demiroglu, Yusuf Ziya; Yabanoglu, Hakan; Demir, Senay; Caliskan, Kenan; Moray, Gokhan; Arslan, HandeMucormycosis is a rarely encountered invasive fungal infection with high mortality. Solid organ transplantation is one of the risk factors for mucormycosis. Mucormycosis can be classified in six different groups according to the anatomical localization; rhinocerebral, pulmonary, cutaneous, gastrointestinal, disseminated, and other less common involvements. This paper presented a mucormycosis case with rhinoorbitocerebral involvementin a renal transplantation receiver, which manifested with orbital apex syndrome.Item A single-center experience of post-transplant lymphoproliferative disorder (PTLD) cases after pediatric liver transplantation: Incidence, outcomes, and association with food allergy(2018) Haberal, Mehmet; Haberal, Nihan; Baris, Zeren; Ozcay, Figen; Ozbek, Ozlem Yilmaz; Sarialioglu, Faik; 29755021; AAB-4153-2020Background/Aims: We evaluated our 16-year single-center experience of pediatric post-transplant lymphoproliferative disorder (PTLD) cases who underwent liver transplantation between 2001 and 2017. Materials and Methods: Of the 236 pediatric patients who underwent liver transplantation between 2001 and 2017, the clinical and laboratory data of eight patients diagnosed with PTLD were reviewed. The pre-transplant Epstein-Barr virus (EBV) status of 172 patients was also recorded. Results: The total incidence of PTLD was 3.4%. The incidence of PTLD was 10% in pre-transplant EBV immunoglobulin G (IgG)-seronegative patients and 0.8% in pre-transplant EBV IgG-seropositive patients. The mean age of the patients at liver transplantation was 2.71 +/- 3.21 years, and four patients were aged below 1 year at the time of transplantation. PTLD was diagnosed at 21.81 +/- 18.1 months after transplantation. The primary site of involvement was variable among patients: peripheral and mediastinal lymph nodes, stomach and intestine, transplanted graft, bone marrow, and nasopharynx. The eosinophil count varied greatly among patients, with a mean value of 524.62 +/- 679/mm3. Three patients had a food allergy and were administered an elimination diet at the time of PTLD diagnosis. Six patients had PTLD of B-cell origin. One patient died due to neutropenic sepsis during chemotherapy, whereas seven patients were followed up in full remission for 7.75 +/- 4 years. Conclusion: PTLD is a life-threatening complication of solid-organ transplantation with a heterogeneous clinical spectrum. Food allergy had a close association with PTLD. A close follow-up of patients with risk factors and an early diagnosis with appropriate treatment may lead to a better outcome.
