[Cutaneous microcirculation in infectious endocarditis].
Nailfold capillary microscopy was used to study the microcirculation patterns in 26 adult patients with infective endocarditis. Abnormal patterns were found in 13 patients (50%). Enlargement of capillary loops was never observed. Significant correlations were found between the number of capillary abnormalities and both systemic involvement (cutaneous vasculitis, arthritis, splenomegaly and/or glomerulonephritis) and immunological disturbances (circulating immune complexes, rheumatoid factor and/or hypocomplementemia) (p = 0.02 and 0.003, respectively). Capillary abnormalities were significantly reduced in 14 patients studied 4 to 48 months after endocarditis was cured. However, due to the lack of specificity, nailfold capillary microscopy cannot be regarded as a useful tool for the diagnosis of infective endocarditis. Connective tissue disorders are not the sole diagnosis to be considered in patients with abnormal nailfold capillary microcirculation patterns.
