RESUMO
Chest roentgenograms of 152 patients with type 2/3 disease observed 3 or more years were reviewed using modified ILO/UC nomenclature. After a mean length of observation of 9.3 years, clinical recovery was observed in 71.7% and radiologic recovery in 48.0% of the patients. Age; duration of observation; mediastinal adenopathy; and character (xyz, pgr, stu), size, extent, and profusion of pulmonary densities were similar in the 53 white and 99 black patients, who differed significantly only in sex distribution. White patients achieved clinical recovery (84.9%) more often than black patients (64.7%) (p = .05). Factors influencing clinical recovery were analyzed by means of stepwise logistic linear regression. The initial roentgenographic features were unrelated to outcome; only race and extrathoracic disease proved to have significant predictive value. The probability of clinical recovery is estimated to be .894 in white patients with disease limited to the chest, .697 in white patients with extrathoracic disease, and .760 in black patients without and .454 in black patients with extrathoracic sarcoidosis. Recovery appears to be related not to the severity of the initial pulmonary reaction but to racially associated factors that influence extrathoracic dissemination as well as lung damage.
