Psoriatic arthritis (PsA) is a disease with heterogeneous manifestations in patients who have manifest or latent psoriasis. It comprises both musculoskeletal and non-musculoskeletal manifestations. Active chronic PsA is often accompanied by cardiovascular, psychological and metabolic complications. Although the quantity of disease-modifying antirheumatic drugs (DMARDs) indicated for PsA has increased, clinicians still require some guidance in decision-making. Based on the latest evidence-based research results, the European League Against Rheumatism (EULAR) in 2019 developed the recommendations for the pharmacological management of PsA updated in 2015 with new recommendations. This paper interprets the update contents of the guideline to provide references for the clinical treatment of PsA.
【摘要】目的探讨生长抑素(somatostatin,SS)和表皮生长因子(epidermal growth factor,EGF)在银屑病治疗中的相互作用机制。方法选择2008年1月12月门诊和住院的寻常型银屑病患者68例,用放射免疫法检测正常组织和各期银屑病皮损中SS和EGF的表达。结果进行期银屑病皮损中EGF明显高于静止期、恢复期皮损和正常皮肤(P＜001);各期银屑病皮损与正常皮肤中SS差异无统计学意义(P＜005)。结论SS可能是通过抑制EGF而在银屑病的治疗中起关键作用。
目的 通过对白芍总苷治疗前后寻常型银屑病患者血清中白介素（IL）-22水平的研究，探讨其治疗寻常型银屑病的作用机制。 方法 2009年10月－2010年8月采用双抗体夹心酶联免疫吸附法，检测30例寻常型银屑病患者，经白芍总苷治疗前后及健康对照组20例外周血清中IL-22浓度的变化，分析其在治疗前、后与银屑病皮损面积和严重程度指数（PASI）评分的相关性。 结果 寻常型银屑病患者血清IL-22浓度[（90.50 ± 51.80）pg/mL]较对照组[（40.10 ± 17.20）pg/mL]升高，白芍总苷治疗后血清中IL-22水平[（48.70 ± 23.90）pg/mL]较治疗前降低（P＜0.05），并与对照组差异无统计学意义（P＞0.05）；治疗前、后患者血清IL-22水平与PASI评分呈正相关。结论 白芍总苷可能通过调节IL-22发挥治疗寻常型银屑病的作用。
Objective To assess the efficacy and safety of adalimumab on plaque psoriasis. Methods We searched the MEDLINE (1966 to December 2009), Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 12, 2009), EMbase (1980 to December 2009), CBM (1978 to December 2009), and CNKI (1979 to December 2009) to collect randomized controlled trials (RCTs) of adalimumab for plaque psoriasis. The language was confined to English and Chinese. We screened the retrieved studies according to the predefined inclusion and exclusion criteria, evaluated the quality of included studies, and performed meta-analyses by using the Cochrane Collaboration’s RevMan 4.2 software. Results Three RCTs involving 1?630 patients with chronic moderate or severe plaque psoriasis were included and assessed. At the end of 4th, 8th, 12th and 16th week, the PASI 75s of subcutaneous injection every other week in adalimumab (EOW) group were obviously higher than that of placebo group and methotrexate group. While at the end of 24th week and 60th week, the PASI 75s showed no difference between adalimumab EOW and placebo group. Twelve weeks after subcutaneous injection each week with adalimumab (QW), PASI 75 was obviously higher than those of placebo and EOW groups. However, at the end of 24th week and 60th week, there was no significant difference between adalimumab QW and placebo followed by adalimumab EOW. At end of week 12-16, there was no difference between adalimumab EOW group and placebo group in the incidence of adverse effects, with the exception of pain on injection site and upper respiration viral infection. At week 12-60, there was no difference between adalimumab QW and EOW groups in the incidence of adverse effects, with the exception of all serious adverse effects. Conclusion The limited evidence indicates that subcutaneous injection of adalimumab every other week for 12-16 weeks is safe and efficient for patients with moderate or severe plaque psoriasis. The efficacy can’t be enhanced when the treatment is prolonged to 24 weeks. The once-a-week protocol has no obvious advantage over every other week protocol. More RCTs are required to verify these conclusions owing to the limitations of the present study.
Objective To assess the efficacy and safety of efalizumab in the treatment of psoriasis. Methods Randomized controlled trials (RCT) on efalizumab in the treatment of psoriasis were identified from The Cochrane Library ( issue 1, 2006) , specialized trials registered in Cochrane Skin Group (2006), MEDLINE (1966 - 2006) and EMBASE (1974 - 2006). The quality of the trials was assessed by two reviewers independently. RevMan 4.2.7 software provided by the Cochrane Collaboration was used for statistical analysis. Results Three RCTs involving 1 651 patients were included, all of which were of high methodological quality. All the patients were diagnosed as chronic moderate to severe plaque psoriasis with the age of 18-75 years. Meta-analysis indicated that at week 12, significantly more patients in both 1mg/kg/w and 2 mg/kg/w efalizumab subcutaneous groups achieved PASI50, PASI75, PASI90 improvement compared to the placebo group (Plt;0.0001), while there was no significant difference in PASI50, PASI75 and PASI90 responses between 1mg and 2mg efalizumab groups (P gt;0.05). No serious adverse effects were identified. Extended treatment for another 12w may contribute to further efficacy without increasing toxicty. Conclusions Efalizumab 12w therapy is safe and effective for treating adult patients with moderate to severe plaque psoriasis. More RCTs are required to assess the efficacy of the extended treatment.
Objective To assess the relationship between IFN-γ and psoriasis. Methods We searched The Cochrane Library (Issue 3, 2005), MEDLINE (1996 to 2005) and the China Biological Medicine Database (1978 to 2005). The search was conducted in November 2005. The quality of included clinical controlled trials, case studies and cohort studies was evaluated independently by three reviewers. RevMan 4.2.8 software was used. Results In total, 23 studies were included, involving 612 psoriasis patients and 441 healthy controls. All studies did not provide sufficient detail, on the random sampling and the specificity of the kits used for the analyses. Compared with the controls, the serum or plasma IFN-γ in psoriasis patients showed significantly higher levels (SMD=0.89, 95%CI 0.29 to 1.48; and RR=6.20, 95%CI 1.78 to 21.61). The concentration of IFN-γ in supernatant obtained from cultured cells showed slightly higher levels (SMD=0.99, 95%CI -0.01 to 1.99; and RR=5.54, 95%CI 2.03 to 15.13). Conclusion The evidence currently available shows that the increase of IFN-γ may be relevant to psoriasis. However, these results could be affected by the high risk of selection, confounding and detection bias of included studies. More persuasive evidence, from high quality studies, is needed.
目的：探讨银屑病合并蛋白尿患者的临床特点。方法：回顾性分析1996年1月～2005年8月收治的银屑病合并蛋白尿者临床资料，并与银屑病非蛋白尿者的临床特点比较。结果：银屑病合并不明原因蛋白尿48例，皮肤受累面积与蛋白尿程度无相关关系（P＞0.05），但银屑病合并蛋白尿组的银屑病病程更短,肾脏病理荧光表现为IgA沉积为主。蛋白尿组皮肤受累面积与非蛋白尿组皮肤受累面积比较，无统计学意义（P＞0.05），蛋白尿组和非蛋白尿组的病程也无统计学差异（P＞0.05）。结论：银屑病合并不明原因蛋白尿值得重视，有必要对其发病机制、临床特点、病理特征进行深入的研究。
Therapeutic drug monitoring (TDM) has been more widely used in small molecule agents, such as immuno-suppressants, antiepileptic drugs and antibiotics, with less attention in the field of therapeutic biological agents. Monoclonal drugs represented by tumor necrosis factor alpha (TNF-α) inhibitors have shown a good relationship between exposure and efficacy in clinical studies. There are corresponding guidelines and consensus for the recommendations of TDM based on current research evidence. Therefore, this paper introduced the current evidence, strategies and considerations for TDM in the optimal treatment of adalimumab from the perspective of adalimumab TDM to provide references for the clinical practice of adalimumab TDM.
