    Introdução: O comprometimento respiratório da leptospirose humana pode ser sua principal manifestação clínica e comumente está associado a maior morbimortalidade. Métodos: Objetivando descrever aspectos funcionais respiratórios nessa doença, foram analisados 21 pacientes com oximetrias de pulso e espirometrias em dois momentos: em avaliação inicial e após cerca de 28 dias. Resultados: Dois (9,5%) doentes tinham saturação periférica de oxigênio menor que 95%. Padrões espirométricos normais foram observados em 8 (38,1%) casos; distúrbios ventilatórios restritivos foram inferidos em 7 (33,3%), obstrutivos com capacidade vital forçada reduzida em 4 (19%), e inespecíficos em 2 (9,5%). Espirometrias anormais se associaram a pior escore APACHE II (p=0,02) e anormalidades na radiografia de tórax (p=0,05). Após resolução clínica, verificou-se ganho funcional significativo (p<0,05) no grupo de pacientes com espirometria alterada. Conclusões: Alterações espirométricas foram detectadas no curso da enfermidade e estiveram associadas a pior gravidade clínica e maior freqüência de anormalidades radiológicas torácicas. _________________________________________________________________________________________ ABSTRACT: Introduction: Respiratory impairment may be the main clinical manifestation of human leptospirosis. Methods: With the aim of describing the respiratory functional characteristics of this disease, 21 patients were evaluated using pulse oximetry and spirometry at two times: an initial evaluation and after around 28 days. Results: Two (9.5%) patients presented peripheral oxygen saturation of less than 95%. Normal spirometric patterns were observed in eight (38.1%); cases restrictive ventilatory disorders were inferred in seven (33.3%), obstructive disorders with reduced forced vital capacity in four (19%), and nonspecific disorders in two (9.5%). Abnormal spirometry findings were associated with worse APACHE II scores (p = 0.02) and abnormalities on chest x-ray (p = 0.05). After clinical resolution, significant functional gain was observed (p < 0.05) in the group of patients with abnormal spirometry findings. Conclusions: It was concluded that respiratory functional abnormalities were detected during the course of the disease and were associated with greater clinical severity and higher frequency of chest radiographic abnormalities
