BACKGROUND: Approximately 30% of adult patients with immunoglobulin A (IgA) nephropathy (IgAN) or IgA vasculitis with nephritis (IgAVN) develop end-stage renal disease during long-term follow-up. In particular, patients with nephritic-nephrotic syndrome have an increased risk of rapid progression. Conventional immunosuppressive therapy with corticosteroids (CSs) may be insufficient for disease control and is associated with a number of side effects. Rituximab (RTX) has been shown to be well tolerated and effective in a range of glomerular diseases, but there is little information on its therapeutic potential in IgAN...

BACKGROUND: Chronic kidney diseases (CKD) have emerged as a significant cause of morbidity and mortality in patients infected with human immunodeficiency virus (HIV). However, the detailed study of renal pathological findings currently remains unclear in these Japanese patients. METHODS: A retrospective cohort study was undertaken to investigate renal pathological findings between January 1996 and July 2016. Our study included 20 Japanese HIV-infected patients with CKD; 10 cases had undergone renal biopsies, and 10 cases had undergone autopsies, respectively...

Bullous systemic lupus erythematosus is a rare distinctive subepidermal blistering disorder that can occur in patients with systemic lupus erythematosus (SLE). It is histologically characterized by a neutrophil-predominant infiltrate in the subepidermal region with deposition of immunoglobulins (IgG, IgA, IgM), C3, and auto-antibodies against collagen VII. Herein, we report a case of a 13-year-old girl who presented with bullous SLE and Class III lupus nephritis, which is extremely rare at this age.

INTRODUCTION: Little is known about the prevalence of kidney diseases according to renal biopsy in Israel. Since updated literature worldwide emphasizes changing etiologies of chronic kidney disease, it is crucial to research and define the epidemiology and pathology of kidney disease in Israel. Hereby, we introduce an original review of the prevalence of kidney diseases in our study population, which we believe reflects the prevalence of kidney diseases in the population of Israel. AIMS: To investigate the prevalence of kidney diseases diagnosed by renal biopsy, according to age, gender, race and clinical symptoms...

Hua Su, Chun-Tao Lei, Chun Zhang
Interleukin-6 (IL-6) is a pleiotropic cytokine that not only regulates the immune and inflammatory response but also affects hematopoiesis, metabolism, and organ development. IL-6 can simultaneously elicit distinct or even contradictory physiopathological processes, which is likely discriminated by the cascades of signaling pathway, termed classic and trans-signaling. Besides playing several important physiological roles, dysregulated IL-6 has been demonstrated to underlie a number of autoimmune and inflammatory diseases, metabolic abnormalities, and malignancies...

Henoch-Schönlein purpura (HSP) is typically seen as a self-limiting disease in children, but can present more severely in adults, especially when there is renal involvement. Management of HSP in adults also remains a controversial topic with very few studies evaluating available therapies. In this case, HSP presenting as a combination of severe gastrointestinal involvement and a rapid decline in renal function in an adult patient directed our therapy. The patient was a 48-year-old Caucasian male with no known past medical history, who presented with a combination of purpuric rash over the lower extremities, severe abdominal pain with upper gastrointestinal bleeding and a rapidly increasing serum creatinine, with hematuria...

Glomerulonephritis (GN) affects patients of all ages and is an important cause of morbidity and mortality. Non-selective immunosuppressive drugs have been used in immune-mediated GN but often result in systemic side effects and occasionally fatal infective complications. There is increasing evidence from both preclinical and clinical studies that abnormal activation of receptor and non-receptor tyrosine kinase signalling pathways are implicated in the pathogenesis of immune-mediated GN. Activation of spleen tyrosine kinase (SYK), Bruton's tyrosine kinase (BTK), platelet-derived growth factor receptor (PDGFR), epidermal growth factor receptor (EGFR) and discoidin domain receptor 1 (DDR1) have been demonstrated in anti-GBM disease...

Background.: Full-house immunofluorescence in combination with various histopathologic lesions in the renal biopsies of patients without overt systemic lupus erythematosus (SLE) poses a diagnostic challenge. In this setting, the biopsy findings are sometimes termed non-lupus 'full-house nephropathy' (FHN). It is presently unknown whether idiopathic non-lupus FHN is clinicopathologically and prognostically distinct from lupus FHN. Methods.: We included non-lupus FHN patients and lupus FHN controls (four or more American College of Rheumatology or Systemic Lupus International Collaborating Clinics criteria) who were biopsied between 1968 and 2014 at the Leiden University Medical Centre...

OBJECTIVES: Henoch-Schönlein purpura nephritis and immunoglobulin A nephropathy are two diseases with similar clinical presentations but very different prognoses. Transforming growth factor β1 and monocyte chemoattractant protein-1 have been associated with the development of tissue fibrosis. We examined the development of tubulointerstitial fibrosis and its relationship with Transforming growth factor β1 and monocyte chemoattractant protein-1 expression in these patients. METHODS: Renal tissue samples were collected by renal biopsy from 50 children with Henoch-Schönlein purpura nephritis and 50 children with immunoglobulin A nephropathy...

BACKGROUND: In children with Henoch-Schonlein purpura nephritis (HSPN), the degree of proteinuria has been proven to be not only a sign of kidney damage, but also an accelerator of kidney disease progression. Nephrotic proteinuria at disease onset has been proposed as a predictor of a poor renal outcome. This study aims to assess the clinical and pathological features of HSPN with nephrotic proteinuria in a single center. METHODS: One hundred thirty-seven patients with HSPN who visited Shanghai Children's Hospital from January 2009 to December 2013 were retrospectively reviewed...

Henoch Schönlein purpura (HSP), also known as IgA vasculitis (IgAV), is a systemic small-vessel vasculitis that predominantly affects adolescents and is rare in adults. In many cases, the onset of HSP has been causally linked to an infectious disease. We encountered a case of HSP with severe renal involvement diagnosed by renal biopsy following bacillus Calmette-Guerin (BCG) therapy for bladder cancer. This is of clinical relevance, as intravesical BCG administration is becoming an established therapy for superficial bladder cancer and is supposed to be safe...

INTRODUCTION: IgA vasculitis is a systemic small vessel leukocytoclastic vasculitis characterized by skin purpura, arthritis, abdominal pain and nephritis. Most of the abdominal complications are due to edema and hemorrhage in the small bowel wall, but rarely to acute secondary pancreatitis. CASE REPORT: Here, we report a 53-year-old woman who presented with acute pancreatitis and, secondarily, developed skin purpura and arthritis at the seventh day of the clinical onset...

BACKGROUND: Whether kidney transplantation rates differ by glomerulonephritis (GN) subtype remains largely unknown. METHODS: Using the US Renal Data System, we identified all adult patients with ESRD attributed to 1 of 6 GN subtypes who initiated dialysis in the US (1996-2013). Patients with diabetic nephropathy (DN) and autosomal-dominant polycystic kidney disease (ADPKD) served as "external" non-GN comparators. Using Cox proportional hazards regression, with death considered a competing risk, we estimated hazard ratios [HRs (95% confidence intervals)] for first kidney transplantation, controlling for year, demographics, comorbidities, socioeconomic factors, and Organ Procurement Organization (OPO)...

Rare progression to renal failure imposes a burden on children with IgA vasculitis (Henoch-Schönlein purpura, HSP). An abnormal urinalysis on day 7 (7d-UA) may be a surrogate marker for persistent nephritis, but this has not been established. We retrospectively analyzed the risk factors for persistent nephritis in a cohort of 138 children. Of 35 children with abnormal 7d-UA, 24 (69%) had an abnormal urinalysis 6 months after the diagnosis of HSP, which was significantly more than 6 of 103 children (6%) with normal 7d-UA (P < 0...
