Highly active antiretroviral therapy (HAART) has prolonged many patients' lives, but many cardiac sequelae of HIV are not affected by HAART and continue to develop even with treatment. In addition, HAART itself causes in a high proportion of patients a metabolic syndrome, characterized by lipodystrophy/ lipoatrophy, dyslipidemia and insulin resistance that may be associated with an increase in peripheral artery and coronary artery diseases. Careful cardiovascular evaluation in the course of HIV disease can identify cardiac complications early enough to treat. All HIV-infected patients who are either candidates to antiretroviral therapy or who are already under treatment should undergo an assessment that includes the evaluation of the cardiovascular risk with the available guidelines and the interactions between antiretrovirals and drugs commonly used to treat cardiovascular disease. 相似文献

Highly active antiretroviral therapy (HAART) has prolonged many patients' lives, but many cardiac sequelae of HIV are not affected by HAART and continue to develop even with treatment. In addition, HAART itself causes in a high proportion of patients a metabolic syndrome, characterized by lipodystrophy/lipoatrophy, dyslipidemia and insulin resistance that may be associated with an increase in coronary artery disease and stroke. Careful cardiovascular evaluation in the course of HIV disease can identify cardiac complications early enough to treat. All HIV-infected patients are candidates for antiretroviral therapy and patients already under treatment should undergo an assessment that includes the evaluation of the cardiovascular risk according to the available guidelines. 相似文献

Importance of the field: Despite the efficacy of combination antiretroviral therapy (ART), a large proportion of patients living with HIV/AIDS on ART does not achieve or maintain adequate virological suppression. Therapeutic drug monitoring (TDM) has been utilised to improve treatment outcomes of ART.Areas covered in the review: The potential incorporation of TDM into the clinical HIV management is supported by the existing relationship between drug exposure and efficacy/toxicity, the high inter-patient variability pharmacokinetics, and the accurate, specific and rapid method for drug level determination. The current status of TDM in ART is reviewed in this article with discussions on its feasibility, potential use and limitations.What the reader will gain: Mounting evidence from clinical trials has indicated the potential use of TDM in reducing the rates of treatment failure and adverse effect, avoiding the drug interactions, and special populations, such as children, pregnant women and patients with co-infections. TDM may play an important role even in resource-limited settings, to safeguard expanded use of bioequivalent generic antiretroviral drugs and avoid drug interactions with traditional Chinese medicines.Take home message: TDM is still in the centre of controversy in that several critical issues need to be addressed, such as limited adherence assessment, inappropriate response predictors, insufficient validation of target concentration windows and lack of the quality control of assay. The utility of TDM will remain experimental until more data are obtained from large clinical trials showing the benefit of TDM. 相似文献

在HIV病人的治疗中,高效抗反转录病毒疗法(HAART)在降低发病率和病死率方面都有积极作用。然而,用于HAART的抗反转录病毒药物(ARV)在体内代谢中多有相互影响,主要为彼此的抑制或拮抗作用。因此,HAART在临床应用于不同个体时多会有不同的临床效果和不良反应,用药剂量难以把握。治疗性药物监测(TDM)则可检测用药病人的ARV血浆浓度,在此基础上再结合临床疗效而对用药剂量作出调整。本文综述了TDM在HAART中的运用现状、存在问题以及发展前景。 相似文献

他汀类药物引起的肝损害 总被引:1,自引:0,他引:1
他汀类药物是3-羟基3-甲基戊二酰辅酶A还原酶抑制剂,是目前临床上广泛应用的降脂药物。他汀类药物所致肝损害(SILI)无特殊临床特征,与其他药物所致肝损害类似。SILI以肝细胞型多见,胆汁淤积型不常见,混合型少见。SILI的发生机制可能与药物本身的毒性、继发性效应及免疫机制等有关。高剂量、联合用药、肝病史等是SILI的危险因素。应用他汀类药物期间发生轻度肝损害者可减小药物剂量继续使用;发生中度肝损害者应在减量的同时使用保肝药物;发生严重肝损害者则需停药并采取相应的对症治疗措施。临床医师处方他汀类药物要注意严格掌握用药剂量,加强用药期间的实验室监测,尽量避免联合用药,并应嘱咐患者加强营养、注意休息。肝病患者慎用他汀类药物。大部分患者的SILI是可逆的。 相似文献

Leukotriene-mediated liver injury 总被引:9,自引:0,他引:9
The pathogenic mechanism of fulminant hepatitis induced by 700 mg/kg D-galactosamine plus 33 micrograms/kg endotoxin was investigated in male NMRI mice. The extent of liver injury was assessed by measurement of serum transaminases and sorbitol dehydrogenase activities 9 hr after intoxication, as well as by histopathological evaluation. When the hepatic glutathione content of galactosamine endotoxin-treated animals had been decreased by more than 90% following administration of 250 mg/kg phorone or 400 mg/kg diethyl maleate given three times, no signs of liver injury were observed. Since different agents interfering with the leukotriene synthesis pathway also prevented galactosamine/endotoxin-induced hepatitis, we suspected that a glutathione-derived peptidoleukotriene may be the pathogenic metabolite. In vivo inhibition of the catabolism of leukotriene C4 by administration of 50 mg/kg of the glutamyl transpeptidase inhibitor AT 125 (Acivicin) also protected the animals against liver injury. In order to elucidate which metabolite of leukotriene C4 was responsible for the observed hepatotoxicity we intravenously injected leukotrienes into animals that had received only galactosamine. Injection of 50 micrograms/kg leukotriene E4 1 hr after galactosamine had no effect. The same dose of leukotriene D4 led to a fulminant hepatitis which was prevented when the leukotriene D4 antagonist FPL 55712 had been given before. In contrast, lipoxygenase inhibitors or AT 125 did not protect against galactosamine + LTD4. Galactosamine/endotoxin-induced and galactosamine/leukotriene D4-induced hepatitis resulted in similarly localized histopathological changes, i.e. diffuse necrosis in the organ. We conclude from our results that galactosamine/endotoxin-induced hepatitis is mediated by a leukotriene D4-dependent mechanism. 相似文献

Flucloxacillin is a common cause of drug-induced liver injury in Europe, affecting in the region of 8.5 in every 100,000 first time users of the drug. The mechanism by which the drug causes the liver injury is currently unknown but it is believed to be influenced by a combination of genetic and environmental factors. This review summarises what is currently known about the disposition of flucloxacillin in the liver, considers potential mechanisms by which flucloxacillin may cause the liver injury, and suggests candidate genes which could determine individual susceptibility to flucloxacillin-induced liver injury. 相似文献
