  • Title: [A clinical study of dialysis-related osteoarthropathy in long-term hemodialysis patients].
    Author: Maruyama S.
    Journal: Nihon Jinzo Gakkai Shi; 1998 Nov; 40(8):573-86. PubMed ID: 9893456.
    Abstract:
    Amyloid osteoarthropathy has been seen frequently in long-term hemodialysis (HD) patients, in which the bone X-ray examination reveals characteristic cystic radiolucency (CRL) of the carpal bone, shoulder joint, hip joint and knee joint, and destructive spondylarthropathy (DSA) of cervical vertebrae. To clarify the clinico-pathological significance of CRL and DSA in HD-related amyloidosis, we investigated the grade and frequency of CRL or DSA and these relationship with age, HD duration, primary diseases, osteoarticular symptoms and blood analysis in 817 HD patients (492 male and 325 female, age: 52.6 + 15.5 years, dialysis duration: 6.8 + 5.4 years). The number of cases with osteoarticular symptoms increased with the prolongation of HD duration. CRL and DSA were observed even in patients without osteoarticular symptoms: 26.7% for carpal bone, 26.2% for shoulder joint, 17.3% for hip joint and 22.2% for DSA. The grade and frequency of CRL and DSA also increased in accordance with age and HD duration. In patients with CRL of the carpal bone, shoulder CRL was noticed in 39.7%, hip CRL in 25.8%, and DSA in 14.3% of cases, respectively, and these frequencies increased with the prolongation of HD duration. In the carpal CRL negative group, shoulder CRL was noticed in 14.6%, hip CRL in 7.5%, and DSA in 6.0%, respectively. Although there was no relationship between CRL or DSA and serum beta 2-MG level in any of the cases, the serum beta 2-MG level was lower in patients with HD showing shoulder CRL (+2) and DSA (+) for more than 16 years. No significant relationship was noticed between CRL or DSA and serum C-PTH and aluminum level. These results suggested that aging was related to CRL or DSA formation in dialysis-related amyloidosis. The findings also suggested that systemic bone X-ray examination should be considered in patients with carpal bone CRL, high-age patients and long-term HD patients even without osteoarticular symptoms.
