[Pathology of the microcirculation in Schönlein-Henoch disease according to morphological and biomicroscopic data]

The state of microcirculation in hemorrhagic vasculitis was studied by morphological methods and conjunctival biomicroscopy. Inflammatory, sclerotic, and ataptative changes in terminal vessels of the internal organs and serous membranes are described. The systemic pattern of vascular pathology and selective vulnerability of the venular part (postcapillaries predominantly) in this disease were demonstrated. Morphological data reflecting the functional insufficiency (decompensation) of the local hemo- and lymph-dynamics are presented. A relative comparability of postmortem and biomicroscopic structural changes in the vessels of the microcirculatory bed was established. The method of conjunctival biomicroscopy is considered to be useful clinically not only for the elucidation of the extent of vasculitis activity but also for the evaluation of the effectiveness of treatment.
