A Meta-Analysis of Efficacy and Adverse Effects of Lobaplatin and Cisplatin in the Treatment of Malignant Pleural Effusion / 中国肺癌杂志

BACKGROUND@#The aim of this study is to systematically evaluate the efficacy and adverse effects of Lobaplatin and Cisplatin in the treatment of malignant pleural effusion.@*METHODS@#The databases of Medline (PubMed), Embase, Web of Science, Cochrane, Wanfang, CNKI and VIP were retrieved so as to search the studies about the randomized controlled clinical trials (RCT) that compared the Lobaplatin and Cisplatin for malignant pleural effusion. The main outcome indicators include objective response rate, complete response, partial response, nephrotoxicity, chest pain, gastrointestinal reaction, myelosuppression, fever response and hepatotoxicity. Relative risk was used as the effect size, which was expressed as 95% confidence interval. The meta-analysis was performed using Stata 14.0 statistical software.@*RESULTS@#A total of 12 RCTs and 720 MPE patients were included. The results showed that the ORR (RR=1.27, 95%CI: 1.15-1.40, P<0.001), CR (RR=1.39, 95%CI: 1.09-1.78, P=0.007), PR (RR=1.21, 95%CI: 1.02-1.42, P=0.026) in LBP thoracic perfusion chemotherapy were significantly higher than those in DDP thoracic perfusion chemotherapy. The incidence of nephrotoxicity (RR=0.31, 95%CI: 0.13-0.71, P=0.005) and gastrointestinal reactions (RR=0.44, 95%CI: 0.31-0.62, P<0.001) in the LBP group were significantly lower than those in DDP group.@*CONCLUSIONS@#Compared with DDP pleural perfusion chemotherapy, the ORR, CR and PR of LBP pleural perfusion chemotherapy for MPE are significantly better than DDP, and its nephrotoxicity and gastrointestinal reactions are remarkably lower than DDP.

Ferulic acid lowers body weight and visceral fat accumulation via modulation of enzymatic, hormonal and inflammatory changes in a mouse model of high-fat diet-induced obesity

Previous studies have reported on the glucose and lipid-lowering effects of ferulic acid (FA) but its anti-obesity potential has not yet been firmly established. This study investigated the possible anti-obesitogenic effects of FA in mice fed a high-fat diet (HFD) for 15 weeks. To assess the antiobesity potential of FA, 32 male Swiss mice, weighing 20–25 g (n=6–8 per group) were fed a normal diet (ND) or HFD, treated orally or not with either FA (10 mg/kg) or sibutramine (10 mg/kg) for 15 weeks and at the end of this period, the body weights of animals, visceral fat accumulation, plasma levels of glucose and insulin hormone, amylase and lipase activities, the satiety hormones ghrelin and leptin, and tumor necrosis factor-α (TNF-α) and monocyte chemoattractant protein-1 (MCH-1) were analyzed. Results revealed that FA could effectively suppress the HFD-associated increase in visceral fat accumulation, adipocyte size and body weight gain, similar to sibutramine, the positive control. FA also significantly (P<0.05) decreased the HFD-induced elevations in serum lipid profiles, amylase and lipase activities, and the levels of blood glucose and insulin hormone. The markedly elevated leptin and decreased ghrelin levels seen in HFD-fed control mice were significantly (P<0.05) reversed by FA treatment, almost reaching the values seen in ND-fed mice. Furthermore, FA demonstrated significant (P<0.05) inhibition of serum levels of inflammatory mediators TNF-α, and MCH-1. These results suggest that FA could be beneficial in lowering the risk of HFD-induced obesity via modulation of enzymatic, hormonal and inflammatory responses.

Evaluation of emerging Fusarium mycotoxins beauvericin, Enniatins, Fusaproliferin and Moniliformin in domestic rice in Iran

The occurrence of emerging Fusarium mycotoxins beauvericin [BEA], enniatins [ENNs] [A, A1, B, B1], Fusaproliferin and moniliformin was evaluated by a liquid chromatography/ electrospray ionization-tandem mass spectrometric [LC/ESI-MS/MS] technique in 65 domestic rice samples produced in Gilan and Mazandaran Provinces in Iran. The results showed that 46% of the samples were contaminated with at least one of the emerging mycotoxins. BEA was the most prevalent mycotoxin, which was found in 26 out of 65 rice samples at the concentrations up to 0.47 microg/Kg. Enniatin A1 which was the only member of ENNs was detected in the samples, occurred in 7.7% of samples with an average level of 0.06 microg/Kg. No detectable level of Fusaproliferin and moniliformin was found. This is the first report concerning the contamination of Iranian domestic rice samples with the emerging Fusarium mycotoxins

O efeito da sibutramina na perda de peso de adolescentes obesos / The effect of sibutramine on weight loss in obese adolescents

Objetivo : Avaliar o efeito da sibutramina na perda de peso de adolescentes obesos.Sujeitos e métodos : Estudo duplo-cego placebo controlado tipo cross over com duração de 13 meses. Foram incluídos no estudo 73 adolescentes obesos de ambos os sexos com idades entre 10 e 18 anos. A avaliação antropométrica foi realizada a cada 40 dias em média. Os exames laboratoriais e de imagem foram realizados antes, no período de wash-out e ao final dos 13 meses.Resultados : A porcentagem de pacientes que perderam 10% do peso inicial no placebo foi de 46% e, no grupo sibutramina, foi de 75%. Quando usaram o placebo, o peso em média se elevou em 1,61 kg, e o IMC reduziu em média 0,24 kg/m2, enquanto com o uso da sibutramina o peso reduziu em média 4,47 kg e o IMC reduziu em média 2,38 kg/m2 com p < 0,001.Conclusões : A sibutramina induziu significantemente mais perda de peso em adolescentes obesos em comparação ao placebo, sem efeitos colaterais significativos. A curva de evolução ponderal foi diferente de acordo com o momento em que a sibutramina foi introduzida. Esse achado indica que o melhor momento de introdução da sibutramina é quando a adesão começa a falhar. Arq Bras Endocrinol Metab. 2014;58(3):243-50.

Objective : To evaluate the effect of sibutramine on weight loss in obese adolescents.Subjetcs and methods A double-blind controlled study lasting 13 months. The study included 73 obese adolescents of both sexes aged between 10 and 18 years. Laboratory tests and imaging studies were performed before, during wash-out, and at the end of 13 months.Results : The percentage of patients who lost 10% of their initial weight in the placebo group was 46%, and in the sibutramine group was 75%. When placebo was used, average weight rose by 1.61 kg, and BMI decreased by 0.24 kg/m2 whereas with the use of sibutramine, weight decreased by 4.47 kg, and average BMI decreased, 2.38 kg/m2, with p < 0.001.Conclusions : Sibutramine induced significantly more weight loss in obese adolescents compared with placebo, without significant side effects. The weight loss curve was different depending on the moment sibutramine was introduced. This finding indicates that the best time to start sibutramine is when adhesion begins to fail.

Phase IIa clinical trial of trans-1-amino-3-18F-fluoro- cyclobutane carboxylic acid in metastatic prostate cancer

We performed a phase IIa clinical trial of trans-1-amino-3-[18]Ffluoro-cyclobutane carboxylic acid [anti-[18]F-FACBC], a synthetic amino acid analog for PET, in patients with metastatic prostate cancer. The study subjects consisted of 10 untreated prostate cancer patients having lymph node and/or bone metastasis. Five patients underwent whole-body PET 5 and 30 min after intravenous injection of anti-[18]F-FACBC. The other five patients underwent 60 min dynamic PET of the pelvis. Safety assessment was performed before and 24 h after injection. PET/CT images were assessed visually, and time courses of anti-[18]F-FACBC uptake were evaluated from dynamic imaging. Two mild adverse events were observed and resolved without treatment. All 10 patients showed increased accumulation of anti-[18]F-FACBC in the primary prostate lesion. CT revealed five enlarged lymph nodes indicating metastasis, and all showed increased uptake. Additionally, anti-[18]F-FACBC PET delineated unenlarged lymph nodes as hot spots. Anti-[18]F-FACBC PET demonstrated metastatic bone lesions, similar to conventional imaging. In one of two patients with lung metastasis, some lesions showed increased uptake. Regarding the time course, increased uptake of anti-[18]F-FACBC in the lesion was demonstrated immediately after injection, followed by gradual washout. The results of this phase IIa clinical trial indicated the safety of anti-[18]F-FACBC in patients with prostate cancer and the potential of anti-[18]F-FACBC PET to delineate primary prostate lesions and metastatic lesions. This clinical trial was registered as JapicCTI-101326

Phentermine, Sibutramine and Affective Disorders

A safe and effective way to control weight in patients with affective disorders is needed, and phentermine is a possible candidate. We performed a PubMed search of articles pertaining to phentermine, sibutramine, and affective disorders. We compared the studies of phentermine with those of sibutramine. The search yielded a small number of reports. Reports concerning phentermine and affective disorders reported that i) its potency in the central nervous system may be comparatively low, and ii) it may induce depression in some patients. We were unable to find more studies on the subject; thus, it is unclear presently whether phentermine use is safe in affective disorder patients. Reports regarding the association of sibutramine and affective disorders were slightly more abundant. A recent study that suggested that sibutramine may have deleterious effects in patients with a psychiatric history may provide a clue for future phentermine research. Three explanations are possible concerning the association between phentermine and affective disorders: i) phentermine, like sibutramine, may have a depression-inducing effect that affects a specific subgroup of patients, ii) phentermine may have a dose-dependent depression-inducing effect, or iii) phentermine may simply not be associated with depression. Large-scale studies with affective disorder patients focusing on these questions are needed to clarify this matter before investigation of its efficacy may be carried out and it can be used in patients with affective disorders.

Weight Loss Drugs Recently Approved by the FDA / 임상당뇨병

There have been many advances in obesity treatment, including life-style modification and pharmacological and surgical treatments. It seems that the most remarkable advances in obesity treatment are those of pharmacological strategies. However, weight loss medications have a long history of development. The FDA has withdrawn anti-obesity drugs such as fenfluramine, dexfenfluramine, and phenylpropylamine due to unwanted side effects. Sibutramine was voluntarily withdrawn from the market, and new drugs such as rimonabant have been suspended in the middle of clinical study due to unacceptable side effects. Last year, the FDA approved two new anti-obesity drugs for the treatment of obesity. Lorcaserin is a selective 5-hydroxytryptamine receptor 2c (5-HT2c) agonist whose pharmacological mechanism of action is similar to those of fenfluramine and dexfenfluramine. However, lorcaserin is specific for 5-HT2c, which is located almost exclusively in the CNS and is not found on heart valves. Three exciting phase 3 clinical trials for lorcaserin have been published recently. Lorcaserin has been shown to successfully result in weight reduction, and the drug was not found to lead to heart disease, as is the case with some other such drugs. Furthermore, the FDA also approved controlled release phentermine/topiramate (PHEN/TPM CR), a drug composed of immediate-release phentermine and controlled-release topiramate. Weight reduction by PHEN/TPM CR is better than any other anti-obesity drugs in the world. Along with this excellent efficacy, however, come painful side effects that clinicians should consider.

A Case of Dilated Cardiomyopathy with Massive Left Ventricular Thrombus after Use of a Sibutramine-Containing Slimming Product

Sibutramine, which acts as an anti-obesity drug by inhibiting reuptake of serotonin and norepinephrine, has now been banned due to cardiovascular adverse effects. However, despite being banned, it is not uncommon for people to purchase products with sibutramine or its analogues used as adulterants in non-prescription slimming products or health foods available on the internet. Sibutramine has been associated with rare but serious adverse reactions such as cardiac arrhythmia including QT interval prolongation, myocardial infarction, and cardiomyopathy, as well as increases in blood pressure and pulse rate. Here, we report a case of a 32-year-old male who presented with dilated cardiomyopathy with massive left ventricular thrombus after taking unauthorized sibutramine-containing slimming pills sold over the internet.

16 Cases of Anti-obesity Drug Intoxication Experienced in 4 Emergency Departments

PURPOSE: In Korea, few studies have examined the acute toxicity of anti-obesity drugs. The purpose of this study is to analyze the general characteristics and clinical aspect of acute anti-obesity drug intoxication. METHODS: We retrospectively investigated patients admitted to the emergency department after anti-obesity drug intoxication between March, 2004 and February, 2012. The medical records of these patients were reviewed for demographic data, toxicologic history, time elapsed to presentation, clinical symptoms and signs, treatment, and outcome. RESULTS: There were a total of 18 anti-obesity intoxication cases during the study period; of 16 which were included in our study. The purchasing route of the anti-obesity drug was mainly through a doctor's prescription (68.8%), however, some were obtained through the internet and the pharmacies. The mean time to The most commonly ingested anti-obesity drug was sibutramine (31.3%) and many of the cases (62.5%) were multi-drug ingestions. The most common clinical manifestations were gastrointestinal symptoms (94%), but, CNS symptoms (75%) and cardiovascular symptoms (75%) were almost equally present. 13 patients (81%) were discharged after clearance of toxic symptoms and signs with a mean observational period of 7.0 hours. 3 patients were admitted for observation and treatment; of which 1 patient died due to fatal complications. CONCLUSION: Most anti-obesity intoxications show mild toxicity and a nonfatal clinical course. However, the recent trend toward prescribing psychostimulant anti-obesity medication, which can be fatal after an acute overdose, calls physicians' attention to treating of anti-obesity intoxications.

Anti-Obesity Drugs: A Review about Their Effects and Safety

The current recommendations for the treatment of obese people include increased physical activity and reduced calories intake. When the behavioral approach is not sufficient, a pharmacologic treatment is recommended. In past years, numerous drugs have been approved for the treatment of obesity; however, most of them have been withdrawn from the market because of their adverse effects. In fact, amphetamine, rimonabant and sibutramine licenses have been withdrawn due to an increased risk of psychiatric disorders and non-fatal myocardial infarction or stroke. Even if orlistat is not as effective as other drugs in reducing body weight, orlistat is presently the only available choice for the treatment of obesity because of its safety for cardiovascular events and positive effects on diabetic control. Hopefully, more effective and better tolerated anti-obesity drugs will be developed through an improved understanding of the multiple mechanisms and complex physiological systems targeting appetite.

Long-term health benefits of appetite suppressants remain unproven / Benefícios dos inibidores de apetite à saúde a longo prazo permanecem sem comprovação / Beneficios de los inhibidores de apetito en la salud a largo plazo permanecen sin comprobación

Because of the increasing prevalence of obesity, prevention and treatment of overweight has become a major public health concern. In addition to diet and exercise, drugs are needed for patients who failed to lose weight with behavioral treatment. The current article aimed to summarize recent concerns on the safety and efficacy of appetite suppressants. Several appetite suppressants have been banned for safety reasons. In 2010, sibutramine was withdrawn from the market because a long-term study showed it increased the risks of cardiovascular events. So far no study with a sufficiently large sample size has demonstrated that appetite suppressants can reduce morbidity and mortality associated with overweight. The withdrawal of sibutramine highlights that guidelines for the evaluation of weight control drugs must be more stringent, and studies on their long-term health benefits are needed prior to their marketing.

O aumento da prevalência da obesidade tornou a prevenção e tratamento do sobrepeso importante desafio para a Saúde Pública. Além da dieta e exercício, os medicamentos são necessários para pacientes que não conseguem perder peso com as mudanças comportamentais. O objetivo do artigo foi sumarizar as preocupações atuais com a segurança e efetividade de medicamentos inibidores do apetite. Vários anorexígenos foram banidos por razões de segurança. Em 2010, a sibutramina foi retirada do mercado porque um estudo de longa duração mostrou que ela aumentava o risco de eventos cardiovasculares. Até agora nenhum estudo com número expressivo de pacientes demonstrou que anorexígenos reduzem a morbi-mortalidade associada ao sobrepeso. A retirada da sibutramina do mercado mostra que diretrizes para avaliação de medicamentos anorexígenos devem ser mais rigorosas, e que estudos de longa duração sobre os benefícios para a saúde devem ser realizados antes da comercialização.

Comparison of low-calorie diet with and without sibutramine on body weight and liver function of patients with non-alcoholic fatty liver disease

Non-alcoholic fatty liver [NAFLD] is defined as a spectrum of clinical scenarios which is pathological deposition of fat droplets in the liver of patients who have no history of alcohol use. This study compared the effect of low calorie diet with and without sibutramine on body weight and liver function in patients with NAFLD. This clinical trial study was conducted in 2010 at Tabriz University of Medical Sciences, on 40 obese patients with non-alcoholic fatty liver. Patients were randomly divided into two equal groups of intervention and control groups. Group one received 15 mg daily sibutramine capsules half an hour before lunch and a weight loss diet based on ideal body weight. The other group only had diet control for weight reduction. Before and after 3 months of intervention, weight changes, fasting glucose, glycosylated hemoglobin HbA1c, levels of liver enzymes and ultrasound evaluation was repeated. Data were analyzed using the SPSS software and the paired T test, Mann-Whitney and McNemar test. The mean age of the subjects was 38.90 +/- 7.00 in the sibutramine group and 36.55 _7.87 for the control group. After three months, the average weight loss in sibutramine group was significantly more than the control group sibutramine group13 kg and control group 4 kg [p<0.05]. Improvement in liver echogenicity in sibutramine patients was 90% and 50% of diet group patients. ALT changes in the sibutramine group and control group was 7.50 +/- 15.11 and 6.15 +/- 28.23 respectively, which was statistically significant in the sibutramine group. AST changes were 4.38 +/- 13.37 and 1.70 +/- 18.37 in sibutramine and control group respectively. The changes were not statistically significant. Overall, findings of this study suggest that sibutramine is effective in liver function improvement and treatment of NAFLD patients

Changes of Body Weight and Inflammatory Markers after 12-Week Intervention Trial: Results of a Double-Blind, Placebo-Control Pilot Study

PURPOSE: Low grade inflammation is a well-known characteristic in obese subjects. We investigated body weight changes and inflammatory markers after 12-week intervention trial. MATERIALS AND METHODS: Twenty-six obese subjects were enrolled and 19 (13 men and 6 women) completed the study. Sibutramine is an FDA-approved drug for body weight control; therefore, we chose this drug as the standard treatment medication in this study. Patients were randomly allocated to receive an anti-inflammatory agent (Diacerein treatment group; n = 12) or placebo (n = 7) for 12 weeks. Anthropometry, body proportion by dual-energy X-ray absorptiometry, and metabolic parameters at the beginning and end of study were measured and compared. RESULTS: The treatment group had a tendency towards more reduction in anthropometry as compared to the placebo group, in body weight reduction (- 7.0 kg vs. - 4.6 kg), body mass index (- 2.51 kg/m2 vs. - 1.59 kg/m2), and waist circumference (- 7.3 cm vs. - 4.4 cm). These reductions were not statistically significant. Changes in levels of high-sensitivity C-reactive protein and adiponectin in the treatment group were more favorable than in the placebo group. CONCLUSION: This small pilot study showed no statistical difference for changes in anthropometry, and inflammatory markers between the two groups. Therefore, we could not find any additional effects of Diacerein on weight loss and inflammatory variables in this study.

Sibutramine (Reductil(R))-Induced Cutaneous Leukocytoclastic Vasculitis: A Case Report

A 24-year old woman presented with hemorrhagic vesicles on her legs. She had taken sibutramine (Reductil(R), Abbott Labs., Seoul, South Korea) for 3 months and developed skin lesions the week before. A skin biopsy showed leukocytoclastic vasculitis with conspicuous eosinophilic infiltration of the tissue. These lesions showed improvement after discontinuation of sibutramine. However, 3 months later the skin lesions recurred on other sites on the lower extremities when the patient was rechallenged with the same drug for 2 weeks. Herein, we report the first case of necrotizing vasculitis induced by sibutramine.
