For example, use =CONCATENATE(A1, x) to merge the value in cell A1 with the letter x. CONCATENATE also works well to give results in full sentences: Use =CONCATENATE(The sum of column A is: ,SUM(A:A)) to display column A's sum in a complete sentence.
Microscopic polyangiitis (also known as microscopic polyarteritism, Microscopic polyarteritis nodosa, MPA) is an ill-defined autoimmune disease characterized by a systemic, pauci-immune, necrotizing, small-vessel vasculitis without clinical or pathological evidence of necrotizing granulomatous inflammation.igns and symptoms [edit]. Clinical features may include constitutional symptoms like fever, loss of appetite, weight loss, fatigue, and kidney failure. A majority of patients may have blood in the urine and protein in the urine. Rapidly progressive glomerulonephritis may occur.
Microscopic polyangiitis (MPA) is vasculitis of small vessels. It was initially considered as a microscopic form of polyarteritis nodosa (PAN).In 1990, the American College of Rheumatology developed classification criteria for several types of systemic vasculitis but did not distinguish between polyarteritis nodosa and microscopic polyarteritis nodosa.asculitis in small vessels, including arterioles, capillaries, and venules, a characteristic of MPA, is absent in polyarteritis nodosa. This absence is the proposed distinguishing feature between MPA and PAN.
