Malnutrition-Inflammation Score of Patients with Chronic Kidney Disease from Early Stage to Initiation of Dialysis.

The malnutrition-inflammation score (MIS) is a practical and accessible tool for evaluating protein energy wasting (PEW) in patients on dialysis. However, the severity of PEW at each stage of chronic kidney disease (CKD), especially with late dialysis initiation, is unclear. We evaluated the MIS of 3659 patients with CKD stages 1-5 and the changes in their MIS results at baseline and at the time before dialysis initiation.

NTRK3 exhibits a pro-oncogenic function in upper tract urothelial carcinomas.

Neurotrophic receptor tyrosine kinase 3 (NTRK3) has pleiotropic functions: it acts not only as an oncogene in breast and gastric cancers but also as a dependence receptor in tumor suppressor genes in colon cancer and neuroblastomas. However, the role of NTRK3 in upper tract urothelial carcinoma (UTUC) is not well documented. This study investigated the association between NTRK3 expression and outcomes in UTUC patients and validated the results in tests on UTUC cell lines.

Vitamin D and Diabetic Kidney Disease.

Vitamin D is a hormone involved in many physiological processes. Its active form, 1,25(OH)D, modulates serum calcium-phosphate homeostasis and skeletal homeostasis. A growing body of evidence has demonstrated the renoprotective effects of vitamin D.

Diabetic Kidney Disease in Post-Transplant Diabetes Mellitus: Causes, Treatment and Outcomes.

Kidney transplant recipients are a unique subgroup of chronic kidney disease patients due to their single functioning kidney, immunosuppressive agent usage, and long-term complications related to transplantation. Post-transplant diabetes mellitus (PTDM) has a significant adverse effect on renal outcomes in particular. As transplantations enable people to live longer, cardiovascular morbidity and mortality become more prevalent, and PTDM is a key risk factor for these complications.

Plasma cell-rich related acute rejection in kidney transplant: A case report and review of the literature.

Rationale: Plasma cell-rich acute rejection (PCAR), a subtype of T cell-mediated rejection, is a relatively rare type of acute allograft rejection, that is usually associated with a higher rate of graft failure. However, it is difficult to diagnose PCAR precisely.

Patient Concerns: A 45-year-old woman who had received a kidney transplant presented with acute kidney injury and uremic symptoms approximately 1 year after transplantation.

Whole-exome sequencing identified mutational profiles of urothelial carcinoma post kidney transplantation.

Kidney transplantation is a lifesaving option for patients with end-stage kidney disease. In Taiwan, urothelial carcinoma (UC) is the most common de novo cancer after kidney transplantation (KT). UC has a greater degree of molecular heterogeneity than do other solid tumors.

Association of glomerular filtration rate slope with timely creation of vascular access in incident hemodialysis.

The factors associated with the timely creation of distal vascular access for hemodialysis initiation are unclear. We aimed to explore the association between the slope of estimated glomerular filtration rate (eGFR) and the successful usage of vascular access upon hemodialysis initiation. This single center retrospective cohort study enrolled chronic kidney disease patients who undertook a multidisciplinary care program from 2003 to 2016.

Timing of mTORI usage and outcomes in kidney transplant recipients.

The introduction of mammalian target of rapamycin inhibitors (mTORi) as immunosuppressive agents has changed the landscape of calcineurin inhibitor-based immunosuppressive regimens. However, the timing of mTORi conversion and its associated outcomes in kidney transplantation have conflicting results. This study investigated the effect of early or late mTORi post-transplant initiation on major transplant outcomes, including post-transplant malignancy, in kidney transplant recipients in our center.

Low dose ultraviolet B irradiation at 308 nm with light-emitting diode device effectively increases serum levels of 25(OH)D.

This animal study aimed to elucidate the relationship of low-dose, narrow-band UVB at 308 nm with vitamin D synthesis. C57BL/6 female mice, at 3 weeks-of-age, were randomly divided into the following six groups (n = 6 at each time point of vitamin D measurement), which were: (1) normal diet without UVB irradiation; (2) VDd diet without UVB irradiation; and (3)-(6) VDd diet with 308 nm-UVB irradiation of 12.5, 25, 50, and 100 μω/cm, respectively.

Pyuria, urinary tract infection and renal outcome in patients with chronic kidney disease stage 3-5.

Pyuria is common in chronic kidney disease (CKD), which could be due to either urinary tract infection (UTI) or renal parenchymal inflammation. Only little is known regarding the association of pyuria or UTI with renal outcomes. We investigated 3226 patients with stage 3-5 CKD.

Effect of differences in serum creatinine estimation methodologies on estimated glomerular filtration rate.

Introduction: Serum creatinine is crucial in glomerular filtration rate (GFR) estimation. Various methods of measuring GFR have been developed, which vary in their ability to estimate the prevalence of chronic kidney disease (CKD) and predict consequences associated with CKD. The use of different laboratory devices also results in uncertainty in estimated GFR (eGFR).

Topical tacrolimus and steroids modulate T cells in acute rejection of hand allotransplantation: Two case reports.

Acute rejection is not uncommon after vascularized composite allotransplantation. We reported the effects of adjunctive topical immunosuppressant with topical tacrolimus (Protopic®) and steroid cream (Clobetasol®) in the management of acute rejection in two hand transplantation patients. Case 1 is a 45-year-old male with distal forearm deficit 4 years ago and Case 2 is a 30-year-old male with a proximal forearm deficiency 2 years ago, respectively.

Long-term outcomes of lateral tunneled transposed brachiobasilic arteriovenous fistulas in elderly hemodialysis patient.

Background: Arteriovenous fistula is recommended for the general dialysis population, but its use remains controversial in the elderly population. We evaluated the long-term outcomes of lateral tunneled transposed brachiobasilic arteriovenous fistulas in older patients who underwent hemodialysis.

Methods: In this retrospective cohort study, we included patients who received a two-stage transposed brachiobasilic arteriovenous fistula in a medical center from May 2005 to January 2014.

Hematuria and Renal Outcomes in Patients With Diabetic Chronic KidneyDisease.

Background: Hematuria may indicate nondiabetic renal disease in diabetic chronic kidney disease (CKD). However, some studies have reported that hematuria is noted in diabetic nephropathy and is associated with albuminuria. Hematuria is a risk factor for end-stage renal disease in glomerulonephritis, but its prognostic value in diabetic CKD is unknown.

Diabetic Retinopathy and Clinical Parameters Favoring the Presence of Diabetic Nephropathy could Predict Renal Outcome in Patients with Diabetic Kidney Disease.

Diabetes duration, diabetic retinopathy (DR), and a diagnostic model have been proposed as clinical parameters favoring the presence of diabetic nephropathy (DN) in biopsied patients with diabetic kidney disease. DN, compared with non-diabetic renal disease, had poorer renal outcomes. We tested whether these clinical parameters favoring DN are associated with poorer renal outcomes in non-biopsied patients.

Heart Rate Variability Predicts Major Adverse Cardiovascular Events and Hospitalization in Maintenance Hemodialysis Patients.

Background/aims: Heart rate variability (HRV) has been linked to mortality in maintenance hemodialysis (HD) patients, but it is less clear whether HRV is associated with major adverse cardiovascular events (MACEs) and hospitalization.

Methods: This study enrolled 179 maintenance HD patients. HRV was measured to assess its prognostic significance in relation to MACEs and hospitalization.

Glycosuria and Renal Outcomes in Patients with Nondiabetic Advanced Chronic Kidney Disease.

Sodium glucose cotransporter 2 inhibitors have shown a potential for renoprotection beyond blood glucose lowering. Glycosuria in nondiabetic patients with chronic kidney disease (CKD) is sometimes noted. Whether glycosuria in CKD implies a channelopathy or proximal tubulopathy is not known.

Hyponatremia is Associated with Fluid Imbalance and Adverse Renal Outcome in Chronic Kidney Disease Patients Treated with Diuretics.

Chronic kidney disease (CKD) is frequently complicated with hyponatremia, probably because of fluid overload or diuretic usage. Hyponatremia in CKD population is associated with increased mortality, but the effect on renal outcome was unknown. We investigated whether hyponatremia is associated with fluid status and is a prognostic indicator for adverse outcomes in a CKD cohort of 4,766 patients with 1,009 diuretic users.

Microscopic Haematuria and Clinical Outcomes in Patients With Stage 3-5 Nondiabetic Chronic Kidney Disease.

Microscopic haematuria is proposed as a prognostic factor for renal outcomes in patients with glomerulonephritis. However, the role of haematuria in patients with advanced chronic kidney disease (CKD) or heavy proteinuria has not been investigated. We divided 1799 patients with stage 3-5 nondiabetic CKD into 3 groups according to the results from 3 urinalyses: no haematuria (0-2 red blood cells [RBCs]/hpf ≥2 times), mild haematuria (2-5 RBCs/hpf ≥2 times) and moderate haematuria (≥5-10 RBCs/hpf ≥2 times).

Novel Vitamin D Receptor Mutations in Hereditary Vitamin D Resistant Rickets in Chinese.

Hereditary 1, 25-dihydroxyvitamin D-resistant rickets (HVDRR), a rare recessive disease, is caused by mutation in the VDR gene encoding the vitamin D receptor leading to the resistance to vitamin D. We described a female toddler with initial presentation of leg tenderness and clinical features of HVDRR including severe rickets, hypocalcemia and hypophosphatemia without alopecia. Genetic analysis revealed novel compound heterozygous mutations of p.

Body mass index, mortality, and gender difference in advanced chronic kidney disease.

Background And Aim: A higher body mass index (BMI) appears to be reversely associated with mortality in dialysis patients. Moreover, although women have better survival in chronic kidney disease (CKD), this survival advantage is cancelled in dialysis. The association between BMI and mortality and the gender difference remain controversial in advanced CKD.

Dipyridamole treatment is associated with improved renal outcome and patient survival in advanced chronic kidney disease.

Dipyridamole has been shown to decrease proteinuria and improve renal function progression especially in early chronic kidney disease (CKD) patients with glomerulonephropathy. A combination therapy of dipyridamole with aspirin could prevent second strokes in the general population. Whether these effects of dipyridamole are also true in advanced CKD patients and whether dipyridamole could improve renal outcomes or patient survival is unknown.

Low serum calcium is associated with poor renal outcomes in chronic kidney disease stages 3-4 patients.

Background: Mineral disorders are associated with adverse renal outcomes in chronic kidney disease (CKD) patients. Previous studies have associated hypercalcemia and hypocalcemia with mortality; however, the association between serum calcium and renal outcome is not well-described. Whether adding calcium besides phosphorus or in the form of calcium-phosphorus (Ca×P) product into the model of survival analysis could improve the prediction of renal outcomes is not known.

Atypical X-linked agammaglobulinaemia caused by a novel BTK mutation in a selective immunoglobulin M deficiency patient.

Background: X-linked agammaglobulinaemia (XLA) is the most common inherited humoural immunodeficiency disorder. Mutations in the gene coding for Bruton's tyrosine kinase (BTK) have been identified as the cause of XLA. Most affected patients exhibit a marked reduction of serum immunoglobulins, mature B cells, and an increased susceptibility to recurrent bacterial infections.
