Serial sampling may detect rapid shifts in rheumatoid effusions; single case leaves open generalizability and reversibility.
Case Report (n=1)
Rheumatoid pleural effusions can rapidly evolve over days to develop characteristic low glucose and low pH levels, which appear irreversible once established.
Steven A. Sahn (1980) conducted a case report in Rheumatoid pleurisy (n=1). Rheumatoid pleurisy was evaluated on Pleural fluid pH and glucose level. Over six days, a rheumatoid pleural effusion evolved from normal values to a glucose level of 20 mg/dL and a pH of 6.78.
