Rheumatoid arthritis (RA) is one of the systemic inflammatory diseases, which has a major symptom of multiple arthritis and progressive joint destruction. Since the prevalence of RA is high in elderly women, most RA patients have various diseases and take medications such as hypertension and hyperlipidemia. Among these, the agents that are metabolized by CYP3A and/or transported into the liver by OATP1B are included. According to past animal experiment reports, inflammatory cytokines, especially IL-6 and TNF-alpha, which are key factors in the pathogenesis of RA inhibit the expression of CYP3A at the mRNA level by up-regulating inhibitory transcription factors. Recently, coproporphyrin-I (CP-I) was identified as a specific endogenous substrate of OATP1B1 and OATP1B3. Thus, we evaluate the correlation between inflammatory cytokine levels and CYP3A or OATP1B activities in RA patients using endogenous substrates, 4beta-hydroxycholesterol (4beta-OHC) or CP-I, respectively.

Assessment
Primary outcomes
The prospective study will recruit 100 inpatients or outpatients for 18 years of age or over introduced to the Department of Rheumatology, Oita University Faculty of Medicine, who are not in remission state with DAS 28-CRP score (more than 2.3). Genetic polymorphisms of CYP3A or OATP1B was evaluated by identifying genotypes of single nucleotide polymorphism A6986G (CYP3A5*3) or A388G (SLOC1B1*1b) and T521C (SLOC1B1*5), respectively, using real-time PCR. The concentration of 4beta-OHC in plasma was quantified using gas chromatography-mass spectrometry (GC-MS) previously developed. The plasma CP-I concentration was determined using an ultra-performance liquid chromatography with tandem mass spectrometry (UPLC-MS/MS). The concentrations of inflammatory cytokines (IL-6, TNF-alpha, IL-1beta) in the plasma are measured using each ELISA. The correlation between inflammatory cytokines and plasma 4beta-OHC or CP-I concentration is statistically analyzed using Pearson correlation coefficient or Spearman rank correlation coefficient. Furthermore, using genotypes of CYP3A5*3 or SLOC1B1*1b and SLOC1B1*5, and background, the major factors that influences these concentrations are analyzed by multivariate logistic regression analysis.

Results
37 outpatients with RA were analyzed. OATP1B115 carriers tended to have higher CP-I concentration compared to non-carriers. Plasma CP-I correlated positively with CMPF concentration, but did not correlate with IL-6 or TNF-alpha concentration. Multiple logistic regression analysis by stepwise selection identified plasma CMPF concentration and OATP1B115 allele as significant factors independently affecting plasma CP-I concentration at baseline and at the next visit, respectively.
