Angiotensin-converting enzyme (ACE-I) inhibitors and ARBs have shown real efficacy in reducing blood pressure, proteinuria, in slowing the progression of chronic kidney disease (MRC) and in clinical improvement. in patients with heart failure, diabetes mellitus and ischemic heart disease. However, their use is limited by some side effects such as the increase in serum potassium (K), which can be particularly severe in patients with renal insufficiency. In the 23,000 patients followed by the PIRP project of the Emilia-Romagna Region, hyperkalaemia at the first visit (K> 5...

OBJECTIVE: In epidemiological studies of amyloid A (AA) amyloidosis from Turkey, the most frequently cause was familial Mediterranean fever (FMF) and it occurs generally in young age population. However, there are no sufficient data regarding aetiology, clinical presentation and prognosis of renal AA amyloidosis in advanced age patients. In this study, we aimed to investigate demographic, clinical presentation, aetiology and outcomes of adults aged 60 years or older patients with biopsy-proven renal AA amyloidosis...

BACKGROUND: Hyperlipidaemia is a risk factor for the progression of chronic kidney disease (CKD), which is a frequent comorbidity in patients with HIV-1 infection, but the renal effects of statins remain unclear. METHODS: We performed an observational, prospective study of HIV-infected patients on suppressive antiretroviral therapy, with CKD and hyperlipidaemia, and starting a lipid-lowering treatment with rosuvastatin, atorvastatin or omega-3 fatty acids. CKD was defined as an estimated glomerular filtration rate (eGFR) ≤ 60 mL/min/1...

Fabry disease is an X-linked genetic deficiency in the alpha-galactosidase enzyme resulting in intracellular accumulation of glycosphingolipids and multisystem organ dysfunction. Typically 50% of males and 20% of affected females have renal involvement, ranging from proteinuria or reduced renal function, renal parapelvic cysts and progressive renal disease ultimately requiring transplantation or dialysis. The phenotypic presentation of Fabry disease is incredibly varied and will even vary between family members with the same confirmed genetic mutation...

BACKGROUND: Pre-exposure prophylaxis (PrEP) with tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC) is becoming increasingly adopted for HIV prevention. Tenofovir can cause proximal tubular damage and chronic kidney disease in HIV-infected persons, but little is known regarding its nephrotoxic potential among HIV-uninfected persons. In this study, we evaluated the effects of PrEP on urine levels of the following: α1-microglobulin (α1m), a marker of impaired tubular reabsorption; albuminuria, a measure of glomerular injury; and total proteinuria...

BACKGROUND: About 40-50% of patients with familial microscopic hematuria (FMH) caused by thin basement membrane nephropathy (TBMN) inherit heterozygous mutations in collagen IV genes (COL4A3, COL4A4). On long follow-up, the full phenotypic spectrum of these patients varies a lot, ranging from isolated MH or MH plus low-grade proteinuria to chronic renal failure of variable degree, including end-stage renal disease (ESRD). METHODS: Here, we performed Whole Exome Sequencing (WES) in patients of six families, presenting with autosomal dominant FMH, with or without progression to proteinuria and loss of renal function, all previously found negative for severe collagen IV mutations...

BACKGROUND/AIMS: Arterial hypertension is one of the leading factors aggravating the course of chronic kidney disease (CKD). It seems that the novel parameters used in the assessment of the blood pressure (BP) load (i.e. central blood pressure, nighttime blood pressure) may be more precise in predicting the cardiovascular risk and the progression of CKD in comparison with the traditional peripheral blood pressure measurements in the office conditions. The aim of the study was to assess the impact of the central, or nighttime blood pressure on the progression of CKD in patients with mild or no-proteinuria (autosomal, dominant polycystic kidney disease or IgA nephropathy)...

Introduction Lupus nephritis (LN) affects nearly 60% of patients with systemic lupus erythematosus and up to 30% of them will progress to end-stage renal disease (ESRD), despite receiving aggressive immunosuppressive therapy. The prognostic value of ISN/RPS classification is controversial. Therefore, we aimed to identify clinical and pathological predictors of outcome in LN patients independent of this classification. Material and methods Thirty-seven patients with LN who underwent percutaneous kidney biopsy between 1997 and 2016 were included in this study...

The clinical application of mycophenolate mofetil (MMF) has significantly widened beyond the prophylaxis of acute and chronic rejections in solid organ transplantation. MMF has been recognized as an excellent treatment option in many immunologic glomerulopathies. For children with frequently relapsing nephrotic syndrome (FRNS) or steroid-dependent nephrotic syndrome (SDNS) experiencing steroid toxicity, MMF has been recommended as a steroid-sparing drug. Uncontrolled studies in patients with FRNS and SDSN have shown that many patients can achieve sustained remission of proteinuria with MMF monotherapy...

Transforming growth factor β1 (TGF-β1) plays a central role in chronic kidney diseases. TGF-β1 induction causes podocyte injury, which results in proteinuria and renal failure. However, the effect of the prostaglandin E2 /E-prostanoid receptor (EP2) on TGF-β1-induced podocyte injury remains unknown. Previous studies have shown that phosphoinositide 3-OH kinase (PI3K)/Akt is widespread in cells, and is vital for the regulation of cell proliferation, differentiation, apoptosis and metabolism. In this study, we cultured immortalized mouse podocytes in vitro in different groups: control group; TGF-β1 (5ng/ml) group; EP2 agonist Butaprost treatment (10-7, 10-6, or 10-5mol/L) +TGF-β1 group; EP2 antagonist AH6809 treatment (10-7, 10-6, or 10-5mol / L) + TGF-β1 group...

BACKGROUND: Renal involvement is common among Asians with systemic lupus erythematosus and long-term renal outcomes have been described in homogeneous Caucasian and East Asian populations with lupus nephritis but data is scarce for other ethnicities. We aimed to evaluate the incidence and risk factors for progressive chronic kidney disease (CKD) in multi-ethnic South-east Asians with lupus nephritis. METHODS: Single-center retrospective cohort study of adults with biopsy-proven lupus nephritis diagnosed between May 2001 and May 2009...

BACKGROUND: Skin and soft tissue infections (SSTIs) are a leading cause of morbidity and mortality among people who inject drugs (PWID). International data indicate up to one third of PWID have experienced an SSTI within the past month. Complications include sepsis, endocarditis and amyloid A (AA) amyloidosis. AA amyloidosis is a serious sequela of chronic SSTI among PWID. Though there is a paucity of literature reporting on AA amyloidosis among PWID, what has been published suggests there is likely a causal relationship between AA amyloidosis and injecting-related SSTI...

Hydralazine is a direct-acting vasodilator, which has been used in treatment for hypertension (HTN) since the 1950s. While it is well known to cause drug-induced lupus (DIL), recent reports are indicating the emergence of the drug-induced anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis (DIV). Herein, we describe two patients (aged 57 and 87 years) who presented with severe acute kidney injury (AKI), proteinuria, and hematuria. Both were receiving hydralazine for the treatment of hypertension...

INTRODUCTION: The role of hepatitis C virus infection as a risk factor for the development and progression of chronic kidney disease in the general population remains unclear. MATERIAL AND METHODS: A systematic review of the published medical literature was performed to assess whether positive anti-HCV serologic status is associated with higher frequency of chronic kidney disease in the adult general population. We used a random-effects model to generate a summary estimate of the relative risk of chronic kidney disease (defined by lowered glomerular filtration rate or detectable proteinuria) with HCV across the published studies...

Monoclonal immunoglobulins (MIg) may play a causal role in C3 glomerulopathy (C3G) by impairing regulation of the alternative pathway of complement. Ninety-five patients with C3G were tested for MIg of which 36 were positive. Their mean age at diagnosis was 60 years and among patient 50 years and older, 65.1% had a MIg. At presentation, median serum creatinine and proteinuria were 1.9 mg/dL and 3.0 g/24 hours. Hematuria was present in 32 (88.9%) patients. Twelve (34.3%) patients had low C3 levels. C3 nephritic factor was detected in 45...
