R. Luukkainen et al., RELATIONSHIP OF RHEUMATOID-FACTOR TO LUNG DIFFUSION CAPACITY IN SMOKING AND NONSMOKING PATIENTS WITH RHEUMATOID-ARTHRITIS, Scandinavian journal of rheumatology, 24(2), 1995, pp. 119-120
We studied the relationship of serum rheumatoid factor (RF) and certai
n other variables to lung diffusion capacity for carbon monoxide (DLCO
) in patients with rheumatoid arthritis (RA). In non-smoking patients
none of the examined variables correlated significantly to DLCO wherea
s in smokers RF showed a significant (p<0.01) negative correlation in
this respect. These results indicate that smoking in connection with R
F may contribute to reduced DLCO in RA patients.
