BACKGROUND: Pauci-immune glomerulonephritis is the most common cause of aggressive glomerulonephritis and occurs as a renal-limited disease or as a component of systemic necrotizing small-vessel vasculitis. It is characterized by paucity of staining for immunoglobulins, by immunofluorescence along with fibrinoid necrosis and crescent formation by light microscopy, while the vast majority of patients have anti-neutrophil cytoplasmic antibodies (ANCA) in their circulation, which also participate in the pathogenesis of the disease...

IgA nephropathy (IgAN) is characterized by a variable clinical course and multifaceted pathophysiology. There is substantial evidence to suggest that complement activation plays a pivotal role in the pathogenesis of the disease. Therefore, complement inhibition using the humanized anti-C5 monoclonal antibody eculizumab could be a rational treatment. We report here a 16-year-old male with the vasculitic form of IgAN who failed to respond to aggressive conventional therapy including high-dose steroids, cyclophosphamide and plasma exchange and who was treated with four weekly doses of 900 mg eculizumab followed by a single dose of 1200 mg...

Small vessel vasculitis is a life-threatening condition and patients typically present with renal and pulmonary injury. Disease pathogenesis is associated with neutrophil accumulation, activation, and oxidative damage, the latter being driven in large part by myeloperoxidase (MPO), which generates hypochlorous acid among other oxidants. MPO has been associated with vasculitis, disseminated vascular inflammation typically involving pulmonary and renal microvasculature and often resulting in critical consequences...

This case presented challenging diagnostic and management issues in a young healthy man who presented with abdominal pain and new-onset hypertension. The differential diagnosis evolved over the course of the clinical presentation. The patient had severe vascular involvement of his renal and basal cerebral arteries that initially was assumed to be due to a vasculitic process or hypercoagulable state. Finally it became apparent that the patient did not have a systemic illness but rather a localized vascular disease most likely due to segmental arterial mediolysis, a rare, under-recognized condition that can potentially be fatal...

Henoch-Schönlein purpura (HSP) is a systemic, small vessel vasculitic disorder that mainly affects joint, skin, gastrointestinal tract and kidneys. It is primarily a disease of children that is typically self-limited, but 10 percent of cases occur in adults where features and outcomes may vary. The underlying pathogenesis of HSP remains unknown. We report a case of HSP that occurred with the onset of acute bacterial endocarditis (ABE) in an otherwise healthy 37-year-old Native American male. The patient presented with fevers, fatigue, abdominal pain and renal failure and was found to have acute left-sided staphylococcal endocarditis...

CONTEXT: Henoch-Schönlein purpura (HSP), a systemic IgA vascultitis, is uncommon in adults, with an incidence rate of 0.1 to 1.2 per million in adults over 20 years old. This vasculitic syndrome can present as an uncommon cause of intestinal obstruction in older patients. We report a case of an older woman with HSP presenting with small bowel obstruction and vasculitic rash. CASE REPORT: We report a 67-year-old woman who presented with small bowel obstruction and skin rash...

PURPOSE OF REVIEW: Acute kidney injury (AKI) is commonplace in most ICUs. In many cases the cause is believed to be multifactorial with sepsis being a major component. However, occasionally intrinsic renal disease will present to the ICU and as such critical care practitioners should be aware of this possibility and the ways in which such conditions may present. RECENT FINDINGS: Although a relatively rare occurrence the treatment for patients with intrinsic renal disease, particularly those who present as part of a vasculitic process, differs considerably from usual organ support employed on intensive care...

Hepatitis C virus (HCV) infection is a systemic disorder which is often associated with a number of extrahepatic manifestations including glomerulopathies. Patients with HCV infection were found to have a higher risk of end-stage renal disease. HCV positivity has also been linked to lower graft and patient survivals after kidney transplantation. Various histological types of renal diseases are reported in association with HCV infection including membranoproliferative glomerulonephritis (MPGN), membranous nephropathy, focal segmental glomerulosclerosis, fibrillary glomerulonephritis, immunotactoid glomerulopathy, IgA nephropathy, renal thrombotic microangiopathy, vasculitic renal involvement and interstitial nephritis...

Focal and segmental glomerulosclerosis (FSGS) is a common histopathological lesion that can represent a primary podocytopathy, or occur as an adaptive phenomenon consequent to nephron mass reduction, a scar from a healing vasculitic lesion, direct drug toxicity or viral infection among other secondary causes. Thus, the presence of an FSGS lesion in a renal biopsy does not confer a disease diagnosis, but rather represents the beginning of an exploratory process, hopefully leading ultimately to identification of a specific etiology and its appropriate treatment...

PURPOSE OF REVIEW: This review aims to provide a state-of-the-art perspective on the role of kidney transplantation in cases of end-stage kidney disease due to antineutrophil cytoplasmic antibody (ANCA) vasculitis. We focus on patient and graft survival in recent years, timing of transplant, impact of ANCA status, and relapse of vasculitis in the allograft. RECENT FINDINGS: Graft and patient outcome compare very favorably with other causes of kidney failure and several recent studies have indicated that these outcomes have improved further in recent years...

Scrub typhus is an acute febrile illness caused by orientia tsutsugamushi, transmitted to humans by the bite of the larva of trombiculid mites. It causes a disseminated vasculitic and perivascular inflammatory lesions resulting in significant vascular leakage and end-organ injury. It affects people of all ages and even though scrub typhus in pregnancy is uncommon, it is associated with increased foetal loss, preterm delivery, and small for gestational age infants. After an incubation period of 6-21 days, onset is characterized by fever, headache, myalgia, cough, and gastrointestinal symptoms...

UNLABELLED: HASH(0x44b4d08) INTRODUCTION: Anti-neutrophil cytoplasmic antibody-associated vasculitis has been associated with many drugs and it is a relatively rare side effect of the antihypertensive drug hydralazine. The diagnosis and management of patients who have anti-neutrophil cytoplasmic antibody-associated vasculitis may be challenging because of its relative infrequency, variability of clinical expression and changing nomenclature. The spectrum of anti-neutrophil cytoplasmic antibody-associated vasculitis is wide and can be fatal...

Hepatitis B can have varied extrahepatic manifestations involving the skin, renal, haematological and nervous systems. Neurological manifestations in hepatitis B may take the form of Guillain-Barré syndrome and secondary systemic vasculitis-related mononeuritis multiplex. The clinical course of hepatitis B-related, vasculitis-related neuropathy is usually subacute to chronic and clinical evolution is relatively benign. To our knowledge, acute hepatitis B-associated vasculitis manifesting as acute distal symmetric polyneuropathy has not been reported...

IgA nephropathy (IgAN) is a very common glomerulonephritis worldwide. In this review, we discuss therapeutic options in four clinical scenarios encountered in patients with IgAN: first is the patient with minor urinary abnormalities where the mainstay of treatment is long-term, regular follow-up to detect renal progression and hypertension. Second is the typical patient presenting with microhematuria, significant but non-nephrotic proteinuria, hypertension, and variable degrees of renal failure. Here the mainstay of treatment is optimized supportive care...
