Rheumatoid arthritis and bronchiectasis. A retrospective study of fourteen cases.
Since 1928, 288 cases of rheumatoid arthritis and bronchiectasis have been reported in the medical literature. The interactions between these two conditions and the etiopathogenic mechanisms they involve remain unclear. During a retrospective study of 100 rheumatoid arthritis patients and 80 bronchiectasis patients, we identified 14 additional patients with both conditions. There were 10 females and four males (ratio 2.5/1). Bronchiectasis was confirmed either by computed tomography of the chest or by bronchography. The respiratory manifestations antedated the joint disease in 12 patients, by a mean interval of 28.5 years. An infectious cause was identified in six cases. Neither the age at onset nor the duration of rheumatoid arthritis were influenced by the presence of bronchiectasis. Seven patients had 15 extraarticular manifestations suggesting potentially severe joint disease. The flares of joint and respiratory symptoms were concomitant in six patients. In six patients, the respiratory manifestations worsened after onset of the joint disease. Tests for rheumatoid factors were positive in 73% of cases. Panhypogammaglobulinemia was found in one case. Ten patients underwent lung function tests, which showed evidence of nonspecific obstructive disease. Overall, our findings are consistent with previous reports in the literature. In patients with predisposing immunogenetic factors, bronchiectasis may be involved in the genesis of rheumatoid arthritis.
