Subacute thyroiditis following seasonal influenza vaccination.

A peritoneal dialysis patient who experienced a repeating attack after a vaccination for influenza while she was being followed and treated succesfully for subacute thyroiditis (SAT) is presented. This case shows SAT as a rare condition following vaccination.. Thus, SAT should be considered as a possible outcome following influenza vaccination and flu-like syndrome

Successful Treatment of Cutaneous Blastomycosis in a Renal Transplant Patient With BK Virus Infection: A Case Report

This is the first case report from Turkey to describe a renal transplant complicated by subcutaneous blastomycosis and BK infection. The cutaneous lesions were successfully treated with amphotericin B and fluconazole. The presence of BK infection led to graft failure. Infections with uncommonly seen organisms should be kept in mind due to the impaired T-cell immunity in transplantation

Unexpected Late Response to Ofatumumab in Adult Post-Transplantation Recurrent Focal Segmental Glomerulosclerosis, Case Report

© 2022 Elsevier Inc.Background: Idiopathic focal segmental glomerulosclerosis is an important cause of kidney failure in adults, which is associated with a high risk of disease recurrence after transplantation. Plasmapheresis, rituximab, immunoadsorption, and high-dose cyclosporine are used to treat post-transplant recurrent focal segmental glomerulosclerosis (rFSGS). However, the response rate is variable, and few options remain for unresponsive patients. Case Report: We present a 44-year-old man with an early post-transplant rFSGS. After peritransplant plasmapheresis, rituximab, and abatacept treatments failed, we employed ofatumumab. After 9 months without apparent benefit, we observed an unexpected partial remission thereafter, without severe side effects. Furthermore, remission has been sustained in 30-month follow-up. Conclusions: We believe ofatumumab can be considered an alternative for patients with plasmapheresis and rituximab-resistant post-transplant rFSGS

A Case of an Accelerated Uremic Neuropathy

We present a 62-year-old man, with a prior history of diabetes mellitus, atherosclerotic heart disease, and chronic renal failure requiring peritoneal dialysis, who developed accelerated uremic sensorimotor polyneuropathy. Our patient significantly improved after effective hemodialysis. Although renal transplantation is a curable therapy for uremic neuropathy, effective dialysis is still an important treatment for the group of patients who cannot undergo renal transplantation

Kidney biopsy in the elderly: diagnostic adequacy and yield

Purpose: The number of kidney biopsies (KB) performed in elderly patients has been increasing. Safety and usefulness of elderly KB have been well established, whereas much less is known about diagnostic adequacy and yield in this patient population. Methods: We performed a retrospective study of KBs in 428 patients from April 2015 to December 2017 at an academic institution. We compared KB from 50 patients aged over 64 (elderly) with KB from 378 patients aged between 18 and 64. Results: Gender ratio, body mass index, systolic and diastolic BP, creatinine values, incidences of AKI at the time of biopsy, INR/aptt values, and platelets were similar between the two groups. eGFR and number of transplant biopsies were lower in the elderly biopsy group. The glomerular yield was similar between the two groups (22 ± 14 vs. 22 ± 13, p = 0.869). The likelihood of obtaining more than ten glomeruli was 87% and 88%, respectively, without a significant difference. Inadequate samples were encountered in 6% of the elderly and 5.6% of the non-elderly KB, again without a significant difference. Samples taken by nephrologist had higher glomerular yield for both groups (25 ± 13 vs. 18 ± 12 overall, 26 ± 14 vs. 18 ± 14 for elderly, p < 0.001 both). Inadequate biopsies were lower in the nephrologist group when all patients were considered (3% vs. 9%, p = 0.025). Results were numerically similar for the elderly patients, but the difference was not statistically significant (2% vs. 8%, p = 0.322). No deaths occurred in both arms. Minor complications were not different for each group (4.5% vs. 4%). There were no major complications in elderly patients. However, the difference did not reach statistical significance. Conclusion: The world is aging, leading to an increased number of KB in older patients. KB in the elderly is a safe, effective, and an indispensable tool for the nephrologist. This study suggests there is no need to fear lower diagnostic adequacy in the decision making of a KB for an elderly patient

Factors Affecting Bone Health in Kidney Transplant Recipients: Klotho Gene Single-Nucleotide Polymorphisms and Other Clinical Features

Objectives: Posttransplant bone diseases are a major cause of morbidity in kidney transplant recipients. We investigated the relationship between klotho gene single-nucleotide polymorphisms and bone diseases after kidney transplant. We also aimed to identify possible risk factors for development of bone disease. Materials and Methods: The study consisted of 251 kidney transplant recipients (164 men and 87 women) with minimum follow-up of 3 years after kidney transplant. Patients with prolonged immobilization, malignancy, parathyroidectomy, glomerular filtration rates less than 30 mL/min/1.73 m2, hypo-or hyperthyroidism, and treatment with drugs that affect bone metabolism were excluded. We investigated the relationship between 6 single-nucleotide polymor-phisms of the klotho gene (rs480780, rs211234, rs576404, rs211235, rs9536314, and rs1207568) and development of osteoporosis, avascular bone necrosis, and persistent hyperparathyroidism. Results: Longer dialysis treatment (odds ratio, 1.13; P = .002) and rs211235 single-nucleotide polymor-phism in the klotho gene (odds ratio, 9.87; P = .001 for GG genotype) were significantly associated with persistent hyperparathyroidism. A higher magnesium level was detected as a protective factor from development of persistent hyperparathyroidism (odds ratio, 0.19; P = .009). Persistent hyperparathyroidism was defined as a risk factor for development of osteopenia/osteoporosis (odds ratio, 2.76; P = .003) and avascular bone necrosis (odds ratio, 2.52; P = .03). Although the rs480780 (odds ratio, 8.73; P = .04) single-nucleotide polymorphism in the klotho gene was defined as a risk factor for development of osteopenia/osteoporosis, none of the klotho single-nucleotide polymorphisms was found to be associated with development of avascular bone necrosis. Conclusions: Persistent hyperparathyroidism could be an important indicator for development of bone disease in kidney transplant recipients. Also, some of the klotho gene single-nucleotide polymorphisms are associated with higher risk for bone disease after kidney transplant

Hemodiyaliz hastalarında panel eeaktif antikor düzeyini etkileyen parametreler

Kan transfüzyon sayısı, transplantasyon ve hamilelik hikayesi hemodiyaliz (HD) hastalarında panel reaktif antikor (PRA) düzeyini etkileyen en önemli üç faktör olarak bilinmektedir. Bu faktörlerin dışında da, PRA duyarlılığının nedeni bilinmeyen bir hasta grubunun da varlığı, diğer olası faktörlerin araştırılmasına yol açmıştır. Çalışmamızda merkezimizde HD programında olan hastaların PRA pozitifliğini etkileyen klinik ve laboratuvar parametreleri araştırmayı planladık. Çalışma grubu 94 kadın, 99 erkek hastadan (yaş ortalaması 44.6±15.8 yıl ve hemodiyaliz süresi 42.2+15.3 ay, 100 HCV(-), 93 HCV(+)) oluşuyordu. Otuz hastada renal transplantasyon hikayesi vardı. PRA düzeyi tayini One Lambda Cell Tray kullanılarak gerçekleştirildi. PRA değeri %30'dan yüksek olan hastaların sonucu pozitif kabul edildi. Hastaların yaş, HD süresi, kan grubu, transplantasyon hikayesi, HCV pozitifliği ve aldığı ortalama haftalık r-HuEPO dozu ile PRA pozitifliği arasındaki korelasyon araştırıldı. Çalışmamızda, HD süresi ve transplantasyon hikayesi ile PRA pozitifliği arasında istatistiksel açıdan anlamlı bir ilişki mevcuttu (PRA (+) ve (-) hastaların sırasıyla HD süresi 50.8+40.5 ay, 37.1+38.9 ay, p =0.028, ve transplantasyon hikayesi olan hastaların PRA (+) olma oranı: %90 iken diğer hastalarda %17.2, p=0.0002 olarak bulundu). Hastaların yaş, cinsiyet, kan grubu, kan transfüzyonu sayısı, HCV enfeksiyonu, r- HuEPO dozu ve PRA pozitifliği arasında bir ilişki bulunmadı. Sonuç olarak, HD süresi ve renal transplantasyon PRA sensitizasyonu etkileyen önemli bir faktörlerdir. Bu konuda daha geniş çalışmalara ihtiyaç vardır. Blood transfusion, previous transplantation and pregnancy are the most important factors that influence the panel reactive antibody (PRA) sensitization in hemodialysis (HD) patients. The presence of PRA positive patients who has not been exposed to common triggering fetors have led the investigators to search for other causes of PRA sensitivity. We planned this study to search for the clinical and laboratory parameters and PRA positivity. Our study group was consisted of 94 female and 99 male patients (mean age: 44.6+15.8, mean HD duration: 42.2+15.3 months, hepatitis markers: 100 HCV (-) and 93 HCV ( +). Thirty of the patients had renal transplantation history. PRA measurement was performed with One Lambda Cell Tray. The patients whose PRA levels were more than 30% were accepted to be PRA positive. There was significant relation between transplantation history, HD duration and PRA levels of the patients (HD duration was 50.8+40.5 and 37.1+38.9 months, p =0.028 in PRA (+) and (-) patients respectively and PRA positivity ratio of patients with previous transplantation and those without were 90% and 17.2%, respectively, p=0.0002). We did not find any signifcant relationship between age, gender, HD duration, blood group, number of blood transfusions, r-HuEPO dose, presence of HCV infection and PRA positivity. In conclusion, HD duration and previous transplantation are important factors influencing PRA positivity
