    ABSTRACT: Over the past 25 years, nailfold capillary microscopy (NCM) has gained diagnostic value in the field of rheumatology based on descriptive data from patients with distinct connective tissue diseases (CTD). We prospectively analysed NCM findings from 116 patients selected for NCM by one of the following indications: (1) suspected diffuse or limited scleroderma or dermatomyositis, (2) evaluation of Raynaud's phenomenon (RP) or (3) suspected small-vessel vasculitis. Nailfold haemorrhages, and enlarged and tortuous nailfold capillaries ('lupus pattern') were found to comparable degrees in patients with CTD and primary RP. Only giant loops, bushy capillaries and avascular areas indicated CTD; 92% of patients with Wegener's granulomatosis (WG) had avascular areas. From all nailfold capillary abnormalities, only bushy capillaries, giant loops and avascular areas support a suspected CTD. A lupus-like pattern is not diagnostic. Avascular areas are a typical abnormality in patients with WG, for which NCM findings have not been described previously.

    ABSTRACT: Scleroderma renal crisis is characterized by intimal thickening of the afferent glomerular arterioles resulting in hypertension and fibrinoid necrosis of the capillary tuff. We report a 67-year-old man with long-standing systemic sclerosis who developed normotensive progressive renal failure, proteinuria, and a nephritic urinary sediment with serum myeloperoxidase-antineutrophil cytoplasmatic antibodies (MPO-ANCA). Renal biopsy showed pauci-immune crescentic glomerulonephritis but none of the typical vascular changes of scleroderma renal crisis. Because comparable cases have recently been reported from Japan, normotensive MPO-ANCA-positive crescentic glomerulonephritis may form an entity of progressive renal failure in scleroderma.
