Item First Reported Case of Echinococcal Disease on a Renal Graft Successfully Treated With Albendazole(2021) Helvaci, Ozant; Dagli, Pinar Akyuz; Ayva, Sebnem; Dalgic, Aydin; Sozen, Hakan; Dizbay, Murat; Arinsoy, Turgay; Derici, Ulver Boztepe; 0000-0002-2280-8778; 30696396; AAK-1967-2021Echinococcal disease is an endemic disease for eastern Mediterranean countries. Various types of kidney involvement have been reported. Here, we report the first case of echinococcal disease on a transplanted kidney in a patient who was successfully treated with albendazole alone. The patient (a 38-year-old female) was evaluated for elevated creatinine levels 7 months after receiving a living-donor allograft. Standard immunosuppression therapy protocols were applied. Tacrolimus level was normal, and the patient was compliant with treatment. Creatinine level was 1.91 mg/dL (baseline: 1.2 mg/dL); proteinuria level was 1300 mg/day. The graft was found to be normal, as evaluated with standard sonographic methods. A kidney biopsy was performed, which showed that part of the cortical parenchyme was infiltrated by echinococcal protoscolices with hooklets. Because there were no cysts present on the graft, we concluded that disease was at an early stage. The patient was given albendazole for 3 months. After therapy, all echinococcal structures disappeared. Her creatinine level dropped to baseline, and proteinuria resolved. Echinococcal disease can affect transplanted kidneys. Albendazole is a valuable treatment option for patients who are not candidates for surgical resection.Item Risk Factors for Urinary Tract Infection After Kidney Transplant: A Retrospective Analysis(2020) Tekkarimaz, Nihan; Ozelsancak, Ruya; Micozkadioglu, Hasan; Caliskan, Kenan; Demiroglu, Yusuf Ziya; Arslan, Ayse Hande; H, Mehmet; 0000-0001-5142-5672; 0000-0001-7631-7395; 0000-0002-0788-8319; 0000-0002-8767-5021; 0000-0002-3462-7632; 31424358; AAE-7608-2021; AAD-9088-2021; AAD-5716-2021; AAJ-7201-2021; AAJ-8097-2021Objectives: Urinary tract infections are the most common type of infections in kidney transplant recipients. They are also important factors for increased morbidity and mortality. The aims of this study were to evaluate the number of urinary tract infections, to identify possible donor/receiver-based risk factors, and to evaluate the impact of these infections on graft function. Materials and Methods: Medical records of patients who had undergone kidney transplant between 2010 and 2017 were retrospectively analyzed. Results: Our study included 145 patients (49 women [33.8%] and 96 men [66.2%]), with mean age of 35.2 +/- 12.4 years. There were 105 episodes of urinary tract infections in 55 of 145 patients (37.9%) during the first year after transplant. Female sex (P = .001), glomerulonephritis as primary kidney disease (P = .04), pretransplant diabetes (P = .05), and presence of ureteral stent (P = .03) were significant risk factors for the development of urinary tract infections. The most frequent pathogens identified were Escherichia coli and Klebsiella pneumoniae. Mean glomerular filtration rate at 12 months was significantly lower in patients with urinary tract infection than in patients without infection (80 +/- 25 vs 68 +/- 28 mL/min; P = .006). Conclusions: In kidney transplant recipients, urinary tract infections are common complications and have negative outcomes on graft function. These infections remain an important disease that requires frequent investigations and new ways of approach for prevention.Item Micronuclei and other nuclear anomalies in buccal epithelial cells of children with chronic kidney disease(2016) Baskin, Esra; Aykanat, Banu; Demircigil, Gonca Cakmak; Buyan, Necla; Gulleroglu, Kaan; Fidan, Kibriya; Bayrakci, Umut Selda; Dalgic, Aydin; Karakayali, Hamdi; Haberal, Mehmet; Burgaz, Sema; 0000-0003-1434-3824; 0000-0003-4361-8508; 0000-0002-3462-7632; 28033104; B-5785-2018; AAJ-8833-2021; AAJ-8097-2021The objective of this study was to reveal the likely genomic instability in children with chronic kidney disease (CKD) using micronucleus (MN) assay on buccal epithelial cells (BEC). We investigated the frequencies of micronuclei and other nuclear anomalies, such as nuclear buds, binucleated cells, condensed chromatin, and karyorrhectic and pyknotic cells in BEC. Children with CKD were grouped as follows: children in the pre-dialysis (PreD) stage (N=17), children on regular haemodialysis (HD) (N=14), and children who have undergone transplantation (Tx) (N=17). As a control group, twenty age-and gender-matched healthy children were selected. The MN frequency in BEC of all groups of children with CKD was significantly elevated (5-to 7-fold) as compared to the control group (p<0.001). In contrast, the frequencies of nuclear buds were not significantly higher in the study groups compared to the control group. The frequencies of binucleated cells and condensed chromatin cells were significantly higher in all subgroups of children with CKD relative to the control group (p<0.001). Our results show that the BEC of pediatric PreD, HD, and Tx patients with CKD display increased cytogenetic, cytokinetic, and cytotoxic effects. They also point to the sensitivity and usefulness of the BEC MN assay in the assessment of genetic susceptibility of patients with CKD.
