BACKGROUND: The clinical course of @entity19834 is typically mild and self-limited. There are, however, several case reports of severe @entity532 following this illness with considerable morbidity and mortality. OBJECTIVES: This study was conducted to investigate, using high-resolution computed tomography (HRCT), the long-term @entity358 after @entity19834 and to identify risk factors (chest radiograph findings, antibody titers, and host factors) that might increase the likelihood of developing the sequelae. METHODS: Thirty-eight @entity1 requiring hospitalization attributable to @entity19834 were recruited by the retrospective examination of hospital records. They underwent HRCT after an interval of 1.0 to 2. 2 years. A control group of 17 @entity1 with the history of @entity1729 was also studied after a similar interval. RESULTS: Abnormal HRCT findings were present in 37% (14/38) of the @entity55 group, compared with 12% (2/17) of the control group. The abnormalities in the @entity55 group, which appeared alone or in combination, included mosaic perfusion (n = 12), @entity4595 (n = 8), bronchial wall thickening (n = 4), decreased vascularity (n = 1), and air trapping on expiratory scan (9 of 29 tested). The area affected by these abnormalities, usually involving 2 or more lobes, corresponded in all cases to the location of the infiltrate on chest radiograph at the time of @entity55 . Between subjects with abnormal HRCT (n = 14) and normal HRCT (n = 24) in the @entity55 group, significant differences were observed in age at the time of @entity55 (mean +/- standard deviation: 5.3 +/- 2. 0 years vs 7.7 +/- 3.4 years) and peak antimycoplasma antibody titer (geometric mean [range of 1 standard deviation]; 1:7943 [3126-19 953] vs 1:3093 [832-11 482]). CONCLUSIONS: We conclude that a considerable proportion of @entity1 with history of @entity19834 have abnormal findings on HRCT, suggestive of small airway obstruction and that younger age and higher antibody titer at the time of @entity55 may be risk factors for these sequelae.
