Background Posttransplant anemia (PTA) is associated with the progression of kidney disease and mortality in kidney transplant recipients. Although the main causes of PTA are recipient factors, donor factors have not been fully investigated. In this study we investigated the association of donor pathological findings with the incidence of PTA in kidney transplant recipients after 3 years of transplantation. Methods We conducted a retrospective cohort study at a single university hospital. A tota...

We report a case of graft intolerance syndrome in which transplant nephrectomy was performed 11 years after kidney transplantation. A 46-year-old man was admitted to our hospital in February 2018 with a mild fever, left lower abdominal pain, and gross hematuria with enlargement of the transplanted kidney. Urinary tract infection was ruled out. Because the symptoms developed after the immunosuppressants had been stopped after kidney graft loss, graft intolerance syndrome was suspected. He had los...

Vascular lesions related to allograft rejection have a big impact on graft survival. As such, investigation of these lesions is important to understand the pathophysiology of rejection and its management. We report a case of kidney transplant graftectomy by severe mixed-type rejection with acute and chronic active vascular lesions caused by non-adherence to immunosuppressive treatment. The patient presented is a 29-year-old male who received a kidney transplantation in July 2011 (ABO compatible)...

Background: Recurrence of IgA nephropathy (IgAN) in the transplanted kidney is associated with graft survival, but no specific treatment is available. Tonsillectomy (TE) reportedly arrests the progression of IgAN in the native kidney. Thus, we conducted a single-center retrospective cohort study to evaluate the effect of TE prior to IgAN recurrence. Methods: Of the 36 patients with biopsy-proven IgAN who underwent kidney transplantation, 27 were included in this study. Nine patients underwent TE...

High protein intake can increase glomerular filtration rate (GFR) in response to excretory overload, which may exacerbate the progression of kidney disease. However, the direct association between glomerular hemodynamic response at the single-nephron level and dietary protein intake has not been fully elucidated in humans. In the present study, we evaluated nutritional indices associated with single-nephron GFR (SNGFR) calculated based on corrected creatinine clearance (SNGFRCr). We retrospectiv...

Sebaceous carcinoma is a rare but progressive malignant skin cancer, and the incidence is approximately five times higher in post-transplant patients than in people who have not received kidney transplants. Sebaceous carcinoma is sometimes found concurrently with visceral cancers and a genetic abnormality, Muir–Torre syndrome. We report the case of a female kidney transplant recipient with sebaceous carcinoma concurrent with colon cancer 10 years after transplantation. A 43-year-old woman was ad...

Methods for estimating nephron number in a clinical setting may be useful for predicting renal outcomes. This study aimed to establish such a method using unenhanced computed tomography (CT) and biopsy-based stereology. Patients or living kidney donors simultaneously subjected to enhanced and unenhanced CT examinations were randomly assigned to development and validation groups. The enhanced CT-measured arterial phase and the venous phase images of kidneys were regarded as the true values for co...
