Are stereotypic rheumatoid factors that frequently expressed in mucosa-associated lymphoid tissue-type lymphomas are rare in the labial salivary glands of patients with Sjögren 's syndrome?
Inflamed labial salivary glands in patients with SS generally harbor 1 or 2 highly expanded B cell clones. The repertoire strongly biased toward stereotypic RFs in salivary gland MALT lymphomas is not a reflection of a similar repertoire in the inflamed salivary glands of patients with SS; rather, in the latter, the repertoire is based on a strong selection advantage of incidental stereotypic RF-expressing B cells.
The concept that alcohol dehydrogenase genotype and alcohol metabolic rate modify the effects of alcohol on plasma HDL concentration is not supported by our results.
