ハンセン病における血漿粘度の動態 The Involvement of Plasma Viscosity of Leprosy Patients in Southern China
To investigate the effects of plasma viscosity to leprosy patients in Southern China, we measured plasma viscosity, plasma fibrinogen and total-cholesterol in 71 patients, with a mean age of 63±27.3 years (range, 22 to 84 years), and the duration of their disease varied from 8 to 69 years. Fifty-one patients had multibacillary leprosy (MB) and 20 had paucibacillary leprosy (PB), according to the diagnostic criteria of World Health Organization-recommended multidrug therapy (WHO-MDT). Plasma viscosity was determined using Low Shear 40 (LS40, Contraves, Switzerland). The shear rate was 0-50 (1/s), temperature was 37±1°C. Plasma fibrinogen and total-cholesterol were determined using the fibrinogen kit (Coagrex, International Reagents Corporation, Japan) and Vision pack (Dainabot, Japan). We found plasma viscosity was in high level in the patients with older age of years, and plasma viscosity was remarkably increased in the leprosy patients (1.54±0.17mPa·s), compared with that of healthy volunteers (1.44±0.06mPa·s, P <0.01). Plasma fibrinogen level was396.6±121.4mg/d1, and total-cholesterol level was 143.3±41.8 mg /dl, these levels were higher than those of healthy volunteers (315.6±97.4 md/dl, 131.8±33.4 mg/dl,respectively). These results suggest the plasma fibrinogen level correlates closely with plasma viscosity and the involvement of plasma viscosity plays an important role in the pathogenesis of leprosy as seen in other infectious diseases.
