The authors report the case of a 33 month-old child who presented some of the classical symptoms of the Henoch-Schoenlein purpura - arthritis, purpuric lesions of the lower extremities - associated with the full-blown picture of a post-infectious glomerulonephritis - low level of C3, proliferation of mesangial cells, exudation with large number of leukocytes, and C3 glomerular deposits. These findings and others previously described suggest that the Henoch-Schoenlein purpura is a syndrome and that some of its manifestations may occur in patients with post-infectious glomerulonephritis.

Background: The factors influencing diffuse crescentic glomerulonephritis renal survival and prognosis remain uncertain. Additionally, there's no literature on the clinical outcomes of IgA nephropathy, lupus nephritis, and IgA vasculitis nephritis in type II patients.
Methods: This study retrospectively examined 107 patients diagnosed with diffuse crescentic glomerulonephritis through biopsy.

IgA vasculitis (IgAV) generally occurs in young people and presents with a tetrad of symptoms: purpura, abdominal pain, arthralgia, and nephritis. However, it may have an atypical course without the typical tetrad. Diffuse alveolar hemorrhage (DAH), heart failure, and stroke are known complications of IgAV but are all very rare.

A 69-year-old Japanese man developed abdominal pain, purpura, proteinuria, and hematuria while receiving treatment for pulmonary tuberculosis. A skin biopsy revealed IgA-positive leukocytoclastic vasculitis, and a renal biopsy showed IgA-positive mesangial proliferative glomerulonephritis with crescent formation. Based on these findings, we diagnosed IgA vasculitis with nephritis (IgAVN) and initiated treatment.

Anti-ETAR (endothelin A receptor) antibodies and anti-CXCR3 (C-X-C motif chemokine receptor 3) antibodies are types of non-HLA (human leukocyte antigens) antibodies that could have some influence on the course of glomerulonephritis. The authors aimed to study the influence of these antibodies' levels on the course of specific glomerulonephritis types. We evaluated the anti-ETAR and anti-CXCR3 antibody levels in the serum of patients with membranous nephropathy (n = 18), focal and segmental glomerulosclerosis (FSGS) (n = 25), systemic lupus erythematosus (n = 17), IgA nephropathy (n = 14), mesangiocapillary glomerulonephritis (n = 6), anti-neutrophil cytoplasmic antibodies (c-ANCA) vasculitis (n = 40), and perinuclear anti-neutrophil cytoplasmic antibodies (p-ANCA) vasculitis (n = 16), and we compared their levels with the control group (n = 22).
