The most common causes of renal disease in rheumatoid arthritis (RA) are glomerulonephritis (GN), amyloidosis, tubulo-interstitial nephritis, and drug toxicity. Our aim was to evaluate the clinicopathologic correlation of renal lesions and to assess the course and prognosis of renal disease in patients with RA. We conducted a prospective observational study in all adult patients with RA between July 2010 and June 2015. The total number of patients studied was 90, with a female:male ratio of 2.3:1. Mean follow-up duration was 30 ± 6...

BACKGROUND AND AIM: The available clinical data are limited in a rare glomerular disease, renal amyloidosis. We aimed to clarify the clinical features of renal amyloidosis from database of the Japan Renal Biopsy Registry (J-RBR). METHODS: We performed a cross-sectional study with database of the J-RBR of the Japanese Society of Nephrology. We identified 281 cases of renal amyloidosis from 20,997 cases enrolled into the J-RBR from 2007 to 2014. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were compared among the levels of ages, amount of urine protein excretion (AUPE) or CKD G stages...

OBJECTIVES: AL amyloidosis affects up to 30% of patients with multiple myeloma (MM), and cardiac involvement is associated with worse outcomes. Traditional screening modalities including EKG, echocardiography and biomarkers have limited value. The aim of this study was to evaluate the clinical and prognostic value of late gadolinium enhancement (LGE) by cardiovascular magnetic resonance (CMR) imaging in patients with plasma cell dyscrasias and suspected cardiac amyloidosis (CA). METHODS: A total of 251 consecutive patients with plasma cell dyscrasias who underwent CMR were enrolled in this study...

Progression of chronic kidney disease (CKD) is inevitable. However, the last decade has witnessed tremendous achievements in this field. Today we are optimistic; the dream of withholding this progression is about to be realistic. The recent discoveries in the field of CKD management involved most of the individual diseases leading the patients to end-stage renal disease. Most of these advances involved patients suffering diabetic kidney disease, chronic glomerulonephritis, polycystic kidney disease, renal amyloidosis and chronic tubulointerstitial disease...

OBJECTIVES: This study evaluated whether diffusion-weighted magnetic resonance imaging (DW-MRI) can be used to diagnose secondary renal amyloidosis looking specifically at the diagnostic efficacy of two apparent diffusion coefficient (ADC) measurement methods as they were used with DW-MRI. METHODS: The study included 24 amyloid nephropathy (AN) patients, 20 chronic kidney disease (CKD) patients, and 20 healthy volunteers (HV). ADC values were measured using two different methods: 1) the method of the region of interest indicators (ROIs) and 2) the method of drawing whole renal parenchyma (WP)...

Interpreting an abnormal serum calcium level in subjects with chronic kidney disease (CKD) requires the simultaneous evaluation of various clinical and laboratory parameters. An excessive intake of calcium salts and vitamin D overdosing may be the most common etiologies of hypercalcemia in individuals with advanced CKD. Nevertheless, it should be noted that such patients are susceptible to all diseases that may cause hypercalcemia in subjects without renal disease. In this report, we describe the case of a male chronic hemodialysis patient who developed asymptomatic hypercalcemia associated with polyarticular swelling...

BACKGROUND: Beta-2 microglobulin (B2M) is considered as a surrogate marker for middle molecule uremic toxins and a key component in dialysis-related amyloidosis. However, few studies have evaluated role of B2M in patients with chronic kidney disease (CKD). OBJECTIVES: The purpose of this study was to evaluate the association of plasma B2M level with some metabolic and cardiac performance factors in patients with CKD. PATIENTS AND METHODS: In this case-control study, we measured plasma B2M level in 86 patients with different stages of CKD and 78 age- and sex-matched individuals, as healthy control group...

The kidneys, as an integral part of the body, are in close functional relationship with other organs. Dysfunction of the relationship with one organ will affect the kidney. Chronic kidney disease (CKD) leads in time to alteration of the relationship of the kidney with other organs, sometimes with severe consequences. Thus, cardiovascular involvement in CKD leads to increased severity of CKD, with an increase in mortality rate. At present, the relationship between the kidney and the lung has been less studied...

North Africa (NAF) is composed of six countries located in the African Sahara, namely the Western Sahara, Morocco, Algeria, Tunisia, Libya, and Egypt. Common features between these countries include similar climate, ecology, population genetics, and the socioeconomic environment. This commonality reflects on the chronic kidney disease (CKD) profile in these countries. While there are some estimates on the epidemiology of end-stage kidney disease, that of earlier stages is unknown. Several national screening programs are currently addressing this issue, such as the EGIPT-CKD project in Egypt and the MAREMAR study in Morocco...

The spectrum of kidney disease-associated monoclonal immunoglobulin and plasma cell malignancies is remarkably broad and encompasses nearly all nephropathologic entities. Multiple myeloma with kidney impairment at presentation is a medical emergency since the recovery of kidney function is associated with survival benefits. In most cases, kidney impairment may be the first clinical manifestation of malignant plasma cell dyscrasias like multiple myeloma and light chain amyloidosis. Multiple myeloma per se cannot be considered a main risk factor for developing acute kidney injury following intravascular administration of iodinated contrast media...

OBJECTIVE: Β2-microglobulin (β2M) associated amyloidosis is an inevitable complication of chronic kidney disease (CKD). Testing β2M in the blood is invasive and expensive. On the other hand, oral fluid is a perfect medium to be explored for public health and disease surveillance. However, it has never been studied if salivary concentration of β2M reflects its concentration in the serum. The current study; therefore, aimed to examine the relationship between salivary and serum β2M in a sample of adult diabetic men with CKD...

Patients with chronic kidney disease (CKD) have high cardiovascular mortality and morbidity and a high risk for developing malignancy. Excessive oxidative stress is thought to play a major role in elevating these risks by increasing oxidative nucleic acid damage. Oxidative stress results from an imbalance between reactive oxygen/nitrogen species (RONS) production and antioxidant defense mechanisms and can cause vascular and tissue injuries as well as nucleic acid damage in CKD patients. The increased production of RONS, impaired nonenzymatic or enzymatic antioxidant defense mechanisms, and other risk factors including gene polymorphisms, uremic toxins (indoxyl sulfate), deficiency of arylesterase/paraoxonase, hyperhomocysteinemia, dialysis-associated membrane bioincompatibility, and endotoxin in patients with CKD can inhibit normal cell function by damaging cell lipids, arachidonic acid derivatives, carbohydrates, proteins, amino acids, and nucleic acids...

INTRODUCTION: Chronic kidney disease (CKD) is an important health care problem with increasing incidence. Early diagnosis, recognition and interventions to avoid the disease progression have great value. Even some risk factors for disease progression have been described; there are still some dark spots. Transforming growth factors (TGFs), particularly bone morphogenetic protein-7 (BMP7) take place in renal fibrosis. Our study aimed to evaluate the association between serum BMP7 levels and the progression of CKD...

Nutraceutically, much of the literature has indicated that an aglycon and its related glycoside would act similarly. However, controversial reports are accumulating. We hypothesize that rutin (RT) and quercetin (QT) pharmacodynamically could act differently. To confirm this, doxorubicin (DR) (8.5 mg/kg) was used to induce rat chronic kidney disease (CKD) and then treated with QT and RT (each 70 mg/kg body weight per day) for 13 weeks. QT exhibited better body weight gaining effect (420 ± 45) vs RT, 350 ± 57 g/rat (p < 0...

Musculoskeletal manifestations in chronic renal insufficiency are caused by complex bone metabolism alterations, now described under the umbrella term of chronic kidney disease mineral- and bone-related disorder (CKD-MBD), as well as iatrogenic processes related to renal replacement treatment. Radiological imaging remains the mainstay of disease assessment. This review aims to illustrate the radiological features of CKD-MBD, such as secondary hyperparathyroidism, osteomalacia, adynamic bone disease, soft-tissue calcifications; as well as features associated with renal replacement therapy, such as aluminium toxicity, secondary amyloidosis, destructive spondyloarthropathy, haemodialysis-related erosive arthropathy, tendon rupture, osteonecrosis, and infection...

Online hemodiafiltration (OL-HDF), first described in 1985, is today a widely prescribed treatment modality for end-stage chronic kidney disease (CKD) patients. Other than in the United States, prescription of the treatment modality is widespread with a steady increase since its inception. Indeed, in Western Europe, more CKD patients receive OL-HDF than peritoneal dialysis, hitherto the second most prescribed therapy after conventional hemodialysis. The rise and success of OL-HDF can be attributed to diverse clinical advantages that have been documented over the last two decades...

SCOPE: The number of patients with chronic kidney disease (CKD) are increasing. Interventions such as controlling hypertension and specific pharmacologic options are recommended. Some nutraceutics may have benefits in this regard. METHODS AND RESULTS: Naringenin (a flavanon), catechin (a flavanol), and quercetin (a flavonol) and rutin (a flavonol rutinoside) were tried on CKD in a Sprague Dawley rat model. Results indicated quercetin to be the most effective therapeutic candidate with respect to renal edema, hypertension, serum creatinine, hematocrit, cardiopathy, aorta calcification, glomerular amyloidosis, erythrocyte depletion in bone marrow, collagen deposition, expressions of TNF-α, cleaved caspase-3, IκBα, PPARα, and serum insulin...

Since beta-2 microglobulin (B2M) is a surrogate marker for middle molecular weight uremic toxins and the major protein component in dialysis-related amyloidosis, it has been frequently studied in dialysis patients. It is not known, however, whether B2M has an impact in patients with chronic kidney disease (CKD) not yet on dialysis. Here we studied the relationship of plasma B2M levels to clinical and cardiovascular outcomes in 142 patients (mean age of 67 years) at different stages of CKD. B2M levels increased with CKD stage and thus were highest in hemodialysis patients...

Dialysis-related amyloidosis (DRA) is a serious complication in patients undergoing long-term dialysis treatment. Deposited β(2)-microglobulin-related amyloid induces various osteoarticular disorders. The pathogenetic interaction of DRA with chronic kidney disease-minenal bone disorder (CKD-MBD) is still unclear, while clinical managements for both osteoarticular disorder and DRA is commonly required in dialysis patients. Recently, practical guidelines for DRA are published in Japan. Those make possible to assess DRA with not only pathological examination but also clinical manifestations, such as carpal tunnel syndrome, destructive spondyloarthropathy, joint pains, and so on...
