The Consideration of the Patients with Rheumatoid Arthritis Successfully Treated with Yokuinin-to-kami / 日本東洋医学雑誌

ABSTRACT

We report on three RA patients successfully treated with Yokuinin-to-ka-kyokatsu-dokkatsu-bofu (Yokuinin-to-kami). The first patient was a 47-year-old woman. In 1983, she visited a nearby hospital due to bilateral wrist joint pain. Her condition was diagnosed as RA. She was treated with gold sodium thiomalate (GST) and non-steroidal anti-inflammatory drugs (NSAIDs), but her symptoms did not improve. She visited our department in 1989. She was treated with Keishi-ka-ryojutsubu-to, Bushi-to which resulted in decreased arthralgia. However, in September 1995, her condition worsened. Administration of Yokuinin-to-kami improved her symptoms as well as her laboratory data after three months of treatment. The second patient was a 50-year-old woman. In 1986, she visited a nearby hospital with bilateral wrist joint pain. Several Kampo formulas were subsequently administered at a pharmacy. In 1991, she visited our hospital and her condition improved after treatment with Keishi-ka-ryojutsu-to-ka-boi-ogi-yokuinin. However, in May 1996, she complained of severe pain and swelling at the right shoulder joint. Treatment with Yokuinin-to-kami improved her symptoms, as well as decreased serum C-reactive protein (CRP). The third case involved a 42-year-old woman who exhibited polyarthralgia in June 1991. She visited a neighborhood hospital and was diagnosed as having RA. She was treated with NSAIDs and bucillamine. She first visited our hospital in1993. We treated her with Keishi-ni-eppi-itto-ka-ryojutsubu and Keishi-shakuyaku-timo-to, but the polyarthralgia worsened in May 1996. Subsequently, we treated her with Yokuinin-to-kami which resulted in improvement symptoms, as well as decreased serum CRP.<br>To identify the target group for Yokuinin-to-kami, we further analyzed the characteristics of the patients successfully treated with this formula. Yokuinin-to-kami was administered to nine patients with RA, and the symptoms in five patients improved, but the remaining patients did not respond. The score of stasis of body fluids and deficiency of blood was not considerably different between the two groups. Interestingly, there was a difference in the variation of joint symptoms throughout the day. Namely, the successfully treated patients complained of joint symptom in the evening more than in the morning. These observations suggest that Yokuinin-to-kami is a useful agent for the treatment of a subset of patients with RA, and that joint pain in the evening might be an indicator for this treatment.
