Eight patients with psoriasis received low-dose cyclosporin (CyA) treatment for an average period of 12 months (range 4-16 months). There was great variability in minimal effective CyA dose. In 50% of the patients long-term treatment was limited by dose reductions necessitated by side-effects. A considerable impairment of renal function during CyA therapy was found. Glomerular filtration rate (GFR) and effective renal plasma flow (ERPF) were measured with 125I-iothalamate and 131I-hippuran, respectively. Both at the end of the active treatment period (GFR-CyA and ERPF-CyA), and 4 months after withdrawal of CyA (GFR-4mo and ERPF-4mo), there was sustained renal impairment: GFR-BL = 97 (64-117), GFR-CyA reduction 17.8% (2.2-31.9%) [P < 0.02], GFR-4mo reduction = 9.8% (5.5-21.5%) ml/min/1.73 m2 (P < 0.05 vs. BL); ERPF-BL = 401 (232-607), ERPF-CyA reduction = 10.1% (7.4-27.3%) [P < 0.05], ERPF-4mo reduction = 13.5% (3.0-32.9%) ml/min/1.73 m2 (P < 0.02). Further studies of the effects on renal function during, and after, long-term therapy of psoriasis with low-dose CyA are warranted.
8例银屑病患者接受低剂量环孢素(CyA)治疗,平均治疗期为12个月(范围4 - 16个月)。最小有效CyA剂量存在很大差异。50%的患者长期治疗因副作用导致剂量减少而受限。发现CyA治疗期间肾功能有相当程度的损害。分别用125I - 碘肽酸盐和131I - 马尿酸测定肾小球滤过率(GFR)和有效肾血浆流量(ERPF)。在积极治疗期结束时(GFR - CyA和ERPF - CyA)以及停用CyA后4个月(GFR - 4mo和ERPF - 4mo),均存在持续性肾功能损害:GFR - BL = 97(64 - 117),GFR - CyA降低17.8%(2.2 - 31.9%)[P < 0.02],GFR - 4mo降低 = 9.8%(5.5 - 21.5%)ml/min/1.73 m2(与BL相比P < 0.05);ERPF - BL = 401(232 - 607),ERPF - CyA降低 = 10.1%(7.4 - 27.3%)[P < 0.05],ERPF - 4mo降低 = 13.5%(3.0 - 32.9%)ml/min/1.73 m2(P < 0.02)。有必要进一步研究低剂量CyA长期治疗银屑病期间及之后对肾功能的影响。
