Meta-analysis of benzodiazepine use in the treatment of insomnia

OBJECTIVE: To systematically review the benefits and risks associated with the use of benzodiazepines to treat insomnia in adults. DATA SOURCES: MEDLINE and the Cochrane Controlled Trials Registry were searched for English-language articles published from 1966 to December 1998 that described randomized controlled trials of benzodiazepines for the treatment of insomnia. Key words included "benzodiazepines" (exploded), "randomized controlled trial" and "insomnia." Bibliographies of relevant articles were reviewed for additional studies and manufacturers of benzodiazepines were asked to submit additional randomized controlled trial reports not in the literature. STUDY SELECTION: Articles were considered for the meta-analysis if they were randomized controlled trials involving patients with insomnia and compared a benzodiazepine with placebo or another active agent. Of the 89 trials originally identified, 45 met our criteria, representing a total of 2672 patients. DATA EXTRACTION: Data were extracted regarding the participants, the setting, details of the intervention, the outcomes (including adverse effects) and the methodologic quality of the studies. DATA SYNTHESIS: The meta-analyses of sleep records indicated that, when compared with placebo, benzodiazepines decreased sleep latency by 4.2 minutes (non-significant; 95% confidence interval (CI -0.7 to 9.2) and significantly increased total sleep duration by 61.8 minutes (95% CI 37.4 to 86.2). Patient-reported outcomes were more optimistic for sleep latency; those randomized to benzodiazepine treatment estimated a sleep latency decrease of 14.3 minutes (95% CI 10.6 to 18.0). Although more patients receiving benzodiazepine treatment reported adverse effects, especially daytime drowsiness and dizziness or light-headedness (common odds ratio 1.8, 95% CI 1.4 to 2.4), dropout rates for the benzodiazepine and placebo groups were similar. Cognitive function decline including memory impairment was reported in several of the studies. Zopiclone was not found to be superior to benzodiazepines on any of the outcome measures examined. INTERPRETATION: The use of benzodiazepines in the treatment of insomnia is associated with an increase in sleep duration, but this is countered by a number of adverse effects. Additional studies evaluating the efficacy of nonpharmacological interventions would be valuable.     

Meta-analysis of benzodiazepine use in the treatment of acute alcohol withdrawal

OBJECTIVE: To analyse the evidence for the efficacy and potential harmful effects of benzodiazepines compared with other therapies in the treatment of acute alcohol withdrawal. DATA SOURCES: MEDLINE and the Cochrane Controlled Trials Registry were searched for English-language articles published from 1966 to December 1997 that described randomized controlled trials (RCTs) of benzodiazepines in the treatment of acute alcohol withdrawal. Key words included "benzodiazepines" (exploded) and "randomized controlled trial." Bibliographies of relevant articles were reviewed for additional RCTs, and manufacturers of benzodiazepines were asked to submit additional RCT reports not in the literature. STUDY SELECTION: Articles were considered for the meta-analysis if they were RCTs involving patients experiencing acute alcohol withdrawal and comparing a benzodiazepine available in Canada with placebo or an active control drug. Of the original 23 trials identified, 11 met these criteria, representing a total of 1286 patients. DATA EXTRACTION: Data were extracted regarding the participants, the setting, details of the intervention, the outcomes (including adverse effects) and the methodologic quality of the studies. DATA SYNTHESIS: The meta-analysis of benefit (therapeutic success within 2 days) showed that benzodiazepines were superior to placebo (common odds ratio [OR] 3.28, 95% confidence interval [CI] 1.30-8.28). Data on comparisons between benzodiazepines and other drugs, including beta-blockers, carbamazepine and clonidine, could not be pooled, but none of the alternative drugs was found to be clearly more beneficial than the benzodiazepines. The meta-analysis of harm revealed no significant difference between benzodiazepines and alternative drugs in terms of adverse events (common OR 0.67, 95% CI 0.34-1.32) or dropout rates (common OR 0.68, 95% CI 0.47-0.97). INTERPRETATION: Benzodiazepines should remain the drugs of choice for the treatment of acute alcohol withdrawal.     

Overview: Cryptococcosis in the patient with AIDS

Cryptococcosis is currently the most common life threatening mycoses found in patients with the acquired immunodeficiency syndrome (AIDS). Extrapulmonary involvement is most frequently seen, especially in the central nervous system and skin. Clinical findings are non-specific, even in patients with meningitis. Threshold for diagnosis of this infection should be low, with serum cryptococcal antigens, blood, urine and sputum cultures for Cryptococcus neoformans performed in febrile AIDS patients. Lumbar puncture should also be performed if unexplained headaches are included in a patient's complaints. There is currently no consensus for the most appropriate treatment strategy and the role of oral azoles versus amphotericin B or amphotericin B with flucytosine remains a serious question in need of further controlled studies. Patients eligible for multicentered trials should be encouraged to participate. Therapy for others should be individualized. This review will address some of these issues.     

硝苯地平缓释片联合缬沙坦治疗原发性高血压疗效和安全性的Meta分析

目的：系统评价硝苯地平缓释片联合缬沙坦治疗原发性高血压的疗效和安全性。方法：计算机检索PubMed、CochraneLi-brary、CBM、CNKI、V1P等数据库,按照纳入和排除标准纳入依硝苯地平缓释片联合缬沙坦治疗原发性高血压的随机对照试验（RCT）,并补充检索纳入研究的参考文献;按Cochrane系统评价方法由两名评价员独立评价纳入文献质量、提取资料并交叉核对无误后,采用RevMan5．1软件进行统计学分析。结果：共纳入4个RCT,包括共450例患者,其研究质量均为C级。Meta分析结果显示：硝苯地平缓释片联合缬沙坦治疗原发性高血压的显效率[RR=1．29,95％CI（1．08～1．55）,P〈O．011、总有效率[RR=I．19,95％CI（1．10～1．29）,P〈0．01]和无效率[RR=0．38,95％CI（0．24～0．62）,P〈0．01]与单用硝苯地平缓释片比较,两组差异有统计学意义,两组有效率差异无统计学意义[RR=I．02,95％CI（0．97～1．32）,P〉0．01]。结论：现有证据表明：硝苯地平缓释片联合缬沙坦治疗原发性高血压在显效率,总有效率和无效率方面优于硝苯地平缓释片单用,不良反应与苯地平缓释片单用无明显差异,但远期疗效尚不清楚,尚需更多高质量的随机双盲对照试验证实。
