Chinese Herbs and Bone Disease

Abstract

Wetreated a patient with an unusual bone disease at least partly associated with Chinese herbs. Seven years after 65-year-old man had begun to consume Chinese herbs, multifocal osteoarthralgias were noted, and the patient was hospitalized for renal dysfunction (serum creatinine, 2.8 mg/dl; urea nitrogen, 19 mg/dl). Fanconi syndromealso was apparent. Arenal biopsy specimen showed tubulo-interstitial fibrosis. Chinese herbs were discontinued and prednisolone was started, but bone and joint pain as well as renal function gradually worsened. Four years later, creatinine was 9.0 mg/dl and alkaline phosphatase was 571 IU//. As bone scintigraphy revealed localized asymmetric lesions, Paget's disease of bone was suspected at first. However, neither osteosclerosis nor hypertrophy was seen in radiographs. Based on a bone specimen histology we diagnosed as mixed-type renal osteodystrophy including osteomalacia and osteitis fibrosa. Mosaic pattern of cement lines was not present.This case was not compatible with either Paget's disease or typical renal osteodystrophy as seen in dialysis patients. Etidronate disodium was effective in alleviating bone symptoms. The patient's bone disorder may be a new disease at least partly related to Chinese herbs independently of nephropathy.

Aristolochic acid nephropathy revisited: a place for innate and adaptive immunity?

“…The absence of inflammatory cells has been reported in a few publications 15,21–23 . In the majority of pathological reports, interstitial inflammation has not been assessed 1–3,5,7,10,24–26,28–36 . In some reports taking into account interstitial inflammation, 12,14,37–41 characterization of the infiltrating cells was not available.…”
