Hydroxychloroquine Sulfate Alleviates Persistent Proteinuria in IgA Nephropathy
Primary IgA NephropathyImmunoglobulin A nephropathy (IgAN) is the most common primary glomerulonephritis in the world.There is to date no curative therapy for patients with IgAN.It is considered that dendritic cells, Toll-like receptor (TLR) 9 and cytokines interleukin-6 (IL-6), and interferon-alpha (IFN-a) and tumor necrosis factor-alpha (TNF-α), play an important role in the aberrant mucosal response. Hydroxychloroquine is an antimalarial agent and had a notable impact on immune activation by the reduction of circulating activated immune cells that including decreased TLR-expressing cells, reduced IFN-secreting plasmacytoid dendritic cells, reduced production of inflammatory cytokines including interferon alpha, IL-6 and TNF alpha. Recent studies showed hydroxychloroquine had a benefit for renal remission and could retard the onset of renal damage in patients with lupus nephritis. hydroxychloroquine may have the potential effect in IgA nephropathy, alleviated the proteinuria and had the renal protect effect. This will be a single center, prospective, randomized, controlled study to assess the utility of hydroxychloroquine in IgAN patients.

Henoch-Schoenlein Purpura NephritisThis study is performed to evaluate the efficacy and safety of various measures in the treatment of HSPN with mild proteinuria in children.
Effectiveness Study on Fosinopril and/or Losartan in Patients With Chronic Kidney Disease Stage...
Chronic Kidney InsufficiencyAngiotensin-Converting Enzyme Inhibitors2 moreThe purpose of this study is to determine whether fosinopril and losartan are effective in the treatment of patients with Chronic Kidney Disease(CKD) stage 3.
Plant Versus Animal Dietary Protein and the Effect on Proteinuria
Kidney InsufficiencyDiabetes Mellitus10 moreThe purpose of this study is to investigate if a diet high in plant protein improves kidney function in patients with kidney insufficiency and diabetes and/or hypertension and/or glomerulonephritis. The study is a non-blinded, randomized, controlled, cross-over-design with two intervention periods of each 14 days. Between the two interventions periods there is a washout period of 14 days. The participants are randomized to start with an individualized diet plan containing either high amounts of animal protein or high amounts of plant protein.
Availability Study of ACTH to Treat Children SRNS/SDNS
ProteinuriaPrimary nephrotic syndrome(NS) is a common children renal disease.About 20% primary nephrotic syndrome are steroid-dependent and steroid-resistant.Low serum cortisol is one of the main relapse reasons.Adrenocorticotropic hormone(ACTH)-induced steroidogenesis improve serum cortisol and also direct melanocortin receptors(MCRs) mediated protective effect on kidney cells. To investigate the efficacy and safety of ACTH to treat NS, total 42 children steroid resistant or steroid dependent NS is enrolling in this multicenter, prospective case series of prescription based treatment with ACTH for NS.

Type 2 Diabetic NephropathyThe investigators hypothesize that, LPD supplemented with ketoanalogs will reduce urine podocyte loss and lower the angiotensinogen level in the urine.
Sitaxsentan in Proteinuric Chronic Kidney Disease
Chronic Kidney DiseaseProteinuria1 morePatients with chronic kidney disease (CKD) have higher blood pressures than the general population. They also tend to have protein leaking into the urine (proteinuria). CKD, high blood pressure and proteinuria independently and together increase the risk of developing atherosclerosis (hardening) of the arteries that leads to diseases such as heart attack and stroke. Although there are a number of drugs available that lower blood pressure, these are not always fully effective. Furthermore, there are even fewer drugs that simultaneously lower blood pressure, reduce proteinuria, and slow down kidney damage in CKD. Recent research has shown that drugs like sitaxsentan not only lower blood pressure but also reduce proteinuria and potentially slow down the progression of CKD [1,2]. Before sitaxsentan can become freely available to individuals with CKD it is important to look at the effects this drug could have on proteinuria and blood pressure.

Dextromethorphan and Silymarin in Chronic Kidney Disease (CKD) Patients
ProteinuriaThe investigators test the renal and cardiovascular protective effects dextromethorphan and silymarin on patients with the proteinuric chronic kidney diseases, who enrolled in our clinical trial, had progressing kidney diseases and merit aggressive anti-inflammatory therapy.
Determination of Kidney Function
Kidney DiseaseProteinuria1 moreMuch more about kidney disorders can be learned by determining kidney function. This research proposes to study the kidneys function by several parameters known as glomerular filtration rate (GFR), Renal Plasma Flow (RPF), and Glomerular Capillary Wall Permselectivity. The study will select patients suffering from different types of kidney diseases. These patients will be selected based on the presence of significant amounts of protein in their urine (proteinuria). Standard blood and urine tests are often unable to provide completely accurate information about the kidney. In order for researchers to have a more accurate idea of kidney function, they will use alternative tests. Test materials (para aminohippurate and inulin) will be injected into patients veins that provides information based on their filtration through the kidneys....
