A randomized,double‐blind,placebo controlled,multi‐center study of intravenous iron sucrose and placebo in the treatment of restless legs syndrome

Iron deficiency may exacerbate symptoms in the Restless Legs Syndrome (RLS). We investigated the effect of intravenous iron sucrose or placebo on symptoms in patients with RLS and mild to moderate iron deficit. Sixty patients with primary RLS (seven males, age 46 (9) years, S‐ferritin ≤45 μg/L) recruited from a cohort of 231 patients were randomly assigned in a 12‐months double‐blind, multi‐centre study of iron sucrose 1000 mg (n = 29) or saline (n = 31). The primary efficacy variable was the RLS severity scale (IRLS) score at week 11. Median IRLS score decreased from 24 to 7 (week 11) after iron sucrose and from 26 to 17 after placebo (P = 0.123, N.S. for between treatment comparison). The corresponding scores at week 7 were 12 and 20 in the two groups (P = 0.017). Drop out rate because of lack of efficacy at 12 months was 19/31 after placebo and 5/29 patients after iron sucrose (Kaplan–Meier estimate, log rank test P = 0.0006) suggesting an iron induced superior long term RLS symptom control. Iron sucrose was well tolerated. This study showed a lack of superiority of iron sucrose at 11 weeks but found evidence that iron sucrose reduced RLS symptoms both in the acute phase (7 weeks) and during long‐term follow up in patients with variable degree of iron deficiency. Further studies on target patient groups, dosing and dosing intervals are warranted before iron sucrose could be considered for treatment of iron deficient patients with RLS. © 2009 Movement Disorder Society     

不同剂量和疗程伐昔洛韦治疗带状疱疹的多中心随机双盲对照研究

目的：比较不同剂量和疗程伐昔洛韦治疗带状疱疹的疗效和安全性。方法：选择带状疱疹患者为研究对象，采用多中心、随机、双盲、对照的临床试验。试验组患者采用伐昔洛韦1000mg每日3次口服，共服7d；对照组患者采用伐昔洛韦300mg每日2次口服，共服10d。用药后第3、6和10天观察疗效和不良反应。结果：共入组128例，全分析集（FAS）分析128例，符合方案集（PPS）分析118例。治疗后第3、6和10天，试验组和对照组患者的症状、体征积分下降值及有效率比较差异无统计学意义（P〉0．05）；疼痛视觉模拟评分法（visnal analogue scale，VAS）值比较，两组间差异无统计学意义（P〉0．05），但入组时疼痛VAS值≥8的患者，FAS集分析显示，在治疗后第6、10天VAS值下降两组均存在统计学差异（P〈0．05）；PPS集分析显示治疗后第10天VAS值下降，两组间存在统计学差异俨〈0．05）。试验组和对照组不良反应发生率分别为17．18％和12．50％．主要为嗜睡和恶心。结论：增加伐昔洛韦用量治疗带状疱疹安全、有效，与较低剂量伐昔洛韦组相比，对疼痛程度较严重的患者能更显著地减轻疼痛。     

The First‐Episode Psychosis Outcome Study: premorbid and baseline characteristics of an epidemiological cohort of 661 first‐episode psychosis patients

Aims: Studies conducted in first‐episode psychosis (FEP) samples avoid many biases. However, very few studies are based on epidemiological cohorts treated in specialized FEP services. The aim of this file audit study was to examine premorbid and baseline characteristics of a large epidemiological sample of FEP. Methods: File audit study of all patients admitted to the Early Psychosis Prevention and Intervention Centre between 1998 and 2000 using a specialized questionnaire. Results: There were 661 patient files included in the study. Premorbid evaluation revealed high rates of substance use disorder (74.1%), history of psychiatric disorder (47.5%), past traumatic events (82.7%) suicide attempts (14.3%) and family history of psychiatric illness (55.6%). Baseline characteristics revealed high intensity of illness (mean CGI 5.5), high prevalence of lack of insight (62%) and high rate of comorbidity (70%). Conclusion: High rates of traumatic events or episodes of mental illness before treatment for FEP must be considered when designing treatment approaches because a too narrow focus on positive psychotic symptoms will inevitably lead to incomplete treatment. Additionally, early intervention programmes need sufficient range of resources to address the multiple challenges presented by FEP patients such as high severity of illness, comorbidities and functional impairment. Finally, observation of an important degree of functional impairment despite short duration of untreated psychosis suggests that while early detection of FEP is a necessary step in early intervention, it may not be sufficient to improve functional recovery in psychosis and that efforts aimed at identifying people during the prodromal phase of psychotic disorders should be pursued.

舒经汤治疗痛经及对患者血液流变学的影响

目的探讨舒经汤治疗原发性痛经的疗效及安全性。方法将62例原发性痛经患者随机分为3组,其中治疗组21例(口服舒经汤)、中药对照组21例(口服痛经宝颗粒)、西药对照组20例(口服双氯芬酸),观察各组的临床疗效、血液流变学变化及不良反应。结果治疗组、中药对照组及西药对照组的总有效率分别为95.2%、90.5%及77.8%。治疗前治疗组的血浆粘度(1.60±0.23)mPa·s,纤维蛋白原(4.40±1.18)g/L,均值略高于健康组,其中血沉均值与健康组比有非常显著差异(P<0.01)。而治疗后血浆粘度(1.34±0.18)mPa·s,纤维蛋白原(3.32±1.27)g/L,均值与健康组比无差异,其中血沉与健康组比较无显著性差异(P>0.05)。治疗组和中药对照组均未见明显不良反应,西药对照组主要表现为消化道反应。结论舒经汤治疗原发性痛经疗效确定,且远期疗效及安全性均优于西药对照组。
