A role of bronchological examination in diagnostics of exogenous alveolitis

Abstract

Eighty patients with exogenous allergic alveolitis (EAA) were examined. EAA was diagnosed using liquid (BALF) and histological (transbronchial) biopsies performed during bronchological examination. Acute phase of alveolitis is accompanied by a high total cytosis (900 000-1 500 000 per 1 ml), lymphocytosis (up to 79%, in average 41.8%), eosinophylia up to 3.7% and morphological surprises, such as lung stroma edema, lymphoid and macrophageal infiltration, fibrin penetration in alveoli. Chronic course of exogenous alveolitis characterized by normal cytosis value, moderate BALF lymphocytosis (up to 22%) and morphological signs, such as interstitial fibrosis, vasculitis, fibroatelectases and patchy emphysema.
