狼疮性肾炎的早期症状有哪些?系统性红斑狼疮(SLE)是一种慢性疾病,其特征在于频繁的疾病发作,需要有效和安全的维持治疗(Chan et al.,2005年; Lai等人,2005年)。由于弥漫性增生性狼疮性肾炎(DPLN)是关于患有SLE的年轻患者的治疗的主要关注点,因此用于控制该群体中DPLN活性的最佳免疫抑制疗法仍然存在争议(Niaudet,2000; Tanaka等人,2004年、2009年)。据报道,静脉内环磷酰胺(CPA)的间歇性每月脉冲甚至对患有儿科发作的SLE的患者也有效(Lehman & Onel,2000);然而,CPA是与骨髓毒性、性腺毒性和继发性恶性肿瘤风险增加相关的有效免疫抑制剂(Chan et al.,2000; Lai等人,2005年)。由于治疗相关的不良事件是SLE患者免疫抑制治疗的主要治疗风险,因此选择安全有效的治疗方案对治疗年轻患者的医生来说是一个很大的困境。因此,用于控制SLE的临床活性的最佳维持治疗,特别是在患有儿科发作的SLE的年轻患者中,仍有待建立(Yang等人,1994; Niaudet,2000; Tanaka等人,2001年)。最近报道,对于SLE患者,霉酚酸酯(MMF)与口服CPA或静脉内CPA的每月间歇脉冲疗法(iv-CPA)一样有效并且毒性更小(Chan等人,2000; Lai等人,2005; Sinclair等人,2007年)。然而,MMF在实体器官移植患者以外的患者中的临床使用尚未得到日本厚生省的批准。另一方面,咪唑立宾(MZR),一种在嘌呤核苷酸的从头途径中的肌苷单磷酸脱氢酶的选择性抑制剂,其作用与MMF非常相似(Burkhardt & Kalden,1997; Yokota,2002),已经成功地用于患有狼疮肾炎的年轻患者的长期治疗而没有任何严重的副作用(Tanaka等人,2004; Yumura等人,2005年)。我们假设钙调神经磷酸酶抑制剂,而不是MZR,可能是一种可行的替代治疗小儿狼疮性肾炎患者(Tanaka et al.,2007 a,2009)。他克莫司(Tac)是一种T细胞特异性钙调神经磷酸酶抑制剂,可阻止辅助性T细胞的激活,从而抑制白细胞介素(IL)-2早期激活基因的转录
Optimal treatment for lupus nephritis in adolescents is still a great challenge. Systemic lupus erythematosus (SLE) is a chronic disease characterized by frequent disease flares for which effective and safe maintenance therapy is required (Chan et al., 2005; Lai et al., 2005). Since diffuse proliferative lupus nephritis (DPLN) is a major concern regarding treatment of young patients with SLE, the optimal immunosuppressive therapy for controlling the activity of DPLN in this population remains controversial (Niaudet, 2000; Tanaka et al., 2004, 2009). Intermittent monthly pulses of intravenous cyclophosphamide (CPA) have been reported to be effective even for patients with pediatric-onset SLE (Lehman & Onel, 2000); however, CPA is a potent immunosuppressive agent associated with myelotoxicity, gonadal toxicity, and an increased risk of secondary malignancy (Chan et al., 2000; Lai et al., 2005). Since therapy related-adverse events are a major therapeutic risk of the immunosuppressive treatment in patients with SLE, selecting a safe and effective treatment protocol poses a big dilemma for physicians treating young patients. Thus, optimal maintenance treatment for controlling the clinical activity of SLE, particularly in young patients with pediatric-onset SLE, remains to be established (Yang et al., 1994; Niaudet, 2000; Tanaka et al., 2001). Mycofenolate mofetil (MMF) has recently been reported to be as effective as and less toxic than oral CPA or monthly intermittent pulse therapy with intravenous CPA (iv-CPA) for SLE patients (Chan et al., 2000; Lai et al., 2005; Sinclair et al., 2007). However, clinical use of MMF, in patients other than those undergoing solid organ transplantation, has not been approved by the Japanese Ministry of Health and Welfare yet. On the other hand, mizoribine (MZR), a selective inhibitor of inosine monophosphate dehydrogenase in the de novo pathway of purine nucleotides, which acts very similar to MMF (Burkhardt & Kalden, 1997; Yokota, 2002), has been successfully used without any serious adverse effects for the long-term treatment of young patients with lupus nephritis (Tanaka et al., 2004; Yumura et al., 2005). We hypothesized that calcineurin inhibitors, other than MZR, might be a feasible alternative treatment for patients with pediatric-onset lupus nephritis (Tanaka et al., 2007a, 2009). Tacrolimus (Tac) is a T-cell-specific calcineurin inhibitor that prevents the activation of helper T cells, thereby inhibiting the transcription of the early activation genes of interleukin (IL)-2
