RESUMO

BACKGROUND & AIMS: Pharmacological management of obesity improves outcomes and decreases the risk of obesity-related complications. This American Gastroenterological Association guideline is intended to support practitioners in decisions about pharmacological interventions for overweight and obesity. METHODS: A multidisciplinary panel of content experts and guideline methodologists used the Grading of Recommendations Assessment, Development and Evaluation framework to prioritize clinical questions, identify patient-centered outcomes, and conduct an evidence synthesis of the following agents: semaglutide 2.4 mg, liraglutide 3.0 mg, phentermine-topiramate extended-release (ER), naltrexone-bupropion ER, orlistat, phentermine, diethylpropion, and Gelesis100 oral superabsorbent hydrogel. The guideline panel used the evidence-to-decision framework to develop recommendations for the pharmacological management of obesity and provided implementation considerations for clinical practice. RESULTS: The guideline panel made 9 recommendations. The panel strongly recommended the use of pharmacotherapy in addition to lifestyle intervention in adults with overweight and obesity (body mass index ≥30 kg/m2, or ≥27 kg/m2 with weight-related complications) who have an inadequate response to lifestyle interventions. The panel suggested the use of semaglutide 2.4 mg, liraglutide 3.0 mg, phentermine-topiramate ER, and naltrexone-bupropion ER (based on moderate certainty evidence), and phentermine and diethylpropion (based on low certainty evidence), for long-term management of overweight and obesity. The guideline panel suggested against the use of orlistat. The panel identified the use of Gelesis100 oral superabsorbent hydrogel as a knowledge gap. CONCLUSIONS: In adults with overweight and obesity who have an inadequate response to lifestyle interventions alone, long-term pharmacological therapy is recommended, with multiple effective and safe treatment options.

RESUMO

In recent years, overseas anti-obesity drugs including amfepramone have flowed into China through the internet or personal import by travelers. Amfepramone is controlled in China and is not available as a pharmaceutical product. It is obtainable either through the internet or imported by individuals across the border. The abuse of amfepramone is causing serious health problems. A method for the detection and quantification of amfepramone and its metabolite cathinone in human hair was developed and fully validated using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Approximately 10 mg of hair was weighed and pulverized with extraction solvent (a mixture of methanol: acetonitrile: 2 mM ammonium formate [pH 5.3] [25:29:46, v/v/v]). The limit of detection (LOD) and the limit of quantitation (LOQ) were 5 and 10 pg/mg, respectively. The method was linear over a concentration range from 10 to 10,000 pg/mg. The accuracy varied from -9.3% to 2.3%, with acceptable intra- and inter-day precision. The validated method was successfully applied to 17 authentic cases. The amfepramone concentrations ranged from 11.7 to 209 pg/mg, with a median of 30.2 pg/mg, and the hair cathinone concentrations ranged from 11.9 to 507 pg/mg, with a median of 54.0 pg/mg. This is the first report of amfepramone concentrations in human hair from amfepramone users. Cathinone can be incorporated into hair after amfepramone use.

RESUMO

Drug combinations are being studied as potential therapies to increase the efficacy or improve the safety profile of weight loss medications. This study was designed to determine the anorectic interaction and safety profile of 5-hydroxytryptophan (5-HTP)/carbidopa + diethylpropion and 5-HTP/carbidopa + phentermine combinations in rats. The anorectic effect of individual drugs or in combination was evaluated by the sweetened milk test. Isobologram and interaction index were employed to determine the anorectic interaction between 5-HTP/carbidopa and diethylpropion or phentermine. Plasma serotonin (5-HT) was measured by ELISA. Safety of repeated doses of both combinations in rats was evaluated using the tail sphygmomanometer, cardiac ultrasound, hematic biometry and blood chemistry. A single oral 5-HTP, diethylpropion or phentermine dose increased the anorectic effect, in a dose-dependent fashion, in 12 h-fasted rats. A dose of carbidopa at 30 mg/kg reduced the 5-HTP-induced plasmatic serotonin concentration and augmented the 5-HTP-induced anorectic effect. Isobologram and interaction index indicated a potentiation interaction between 5-HTP/30 mg/kg carbidopa + diethylpropion and 5-HTP/30 mg/kg carbidopa + phentermine. Chronic administration of experimental ED40 of 5-HTP/30 mg/kg carbidopa + phentermine, but not 5-HTP/30 mg/kg carbidopa + diethylpropion, increased the mitral valve leaflets area. Moreover, there were no other significant changes in cardiovascular, hematic or blood parameters. Both combinations induced around 20% body weight loss after 3 months of oral administration. Results suggest that 5-HTP/30 mg/kg carbidopa potentiates the anorectic effect of diethylpropion and phentermine with an acceptable safety profile, but further clinical studies are necessary to establish their therapeutic potential in the obesity treatment.

RESUMO

Amfepramone (AFP) is an appetite-suppressant drug used in the treatment of obesity. Nonetheless, studies on interindividual pharmacokinetic variability and its association with genetic variants are limited. We employed a pharmacokinetic and pharmacogenetic approach to determine possible metabolic phenotypes of AFP and identify genetic markers that could affect the pharmacokinetic variability in a Mexican population. A controlled, randomized, crossover, single-blind, two-treatment, two-period, and two sequence clinical study of AFP (a single 75 mg dose) was conducted in 36 healthy Mexican volunteers who fulfilled the study requirements. Amfepramone plasma levels were measured using high-performance liquid chromatography mass spectrometry. Genotyping was performed using real-time PCR with TaqMan probes. Four AFP metabolizer phenotypes were found in our population: slow, normal, intermediate, and fast. Additionally, two gene polymorphisms, ABCB1-rs1045642 and CYP3A4-rs2242480, had a significant effect on AFP pharmacokinetics (P < 0.05) and were the predictor factors in a log-linear regression model. The ABCB1 and CYP3A4 gene polymorphisms were associated with a fast metabolizer phenotype. These results suggest that metabolism of AFP in the Mexican population is variable. In addition, the genetic variants ABCB1-rs1045642 and CYP3A4-rs2242480 may partially explain the AFP pharmacokinetic variability.

RESUMO

Staphylococcus aureus, a Gram-positive pathogen, can cause severe inflammation in humans, leading to various life-threatening diseases. The lipoprotein is a major virulence factor in S. aureus-induced infectious diseases and is responsible for excessive inflammatory mediators such as nitric oxide (NO). Short-chain fatty acids (SCFAs) including butyrate, propionate, and acetate are microbial metabolites in the gut that are known to have anti-inflammatory effects in the host. In this study, we investigated the effects of SCFAs on S. aureus lipoprotein (Sa.LPP)-induced NO production in mouse macrophages. Butyrate and propionate, but not acetate, inhibited Sa.LPP-induced production of NO in RAW 264.7 cells and bone marrow-derived macrophages. Butyrate and propionate inhibited Sa.LPP-induced expression of inducible NO synthase (iNOS). However, acetate did not show such effects under the same conditions. Furthermore, butyrate and propionate, but not acetate, inhibited Sa.LPP-induced activation of NF-κB, expression of IFN-β, and phosphorylation of STAT1, which are essential for inducing transcription of iNOS in macrophages. In addition, butyrate and propionate induced histone acetylation at lysine residues in the presence of Sa.LPP in RAW 264.7 cells. Moreover, Sa.LPP-induced NO production was decreased by histone deacetylase (HDAC) inhibitors. Collectively, these results suggest that butyrate and propionate ameliorate the inflammatory responses caused by S. aureus through the inhibition of NF-κB, IFN-β/STAT1, and HDAC, resulting in attenuated NO production in macrophages.

RESUMO

PURPOSE: Nonsteroidal anti-inflammatory drugs (NSAIDs) are common cause of severe cutaneous adverse reactions (SCARs). The present study aimed to investigate the characteristics of SCARs induced by NSAIDs in the Korean SCAR registry. METHODS: A retrospective survey of NSAID-induced SCARs recorded between 2010 and 2015 at 27 university hospitals in Korea was conducted. Clinical phenotypes of SCARs were classified into Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), SJS-TEN overlap syndrome and drug reaction with eosinophilia and systemic symptoms (DRESS). Causative NSAIDs were classified into 7 groups according to their chemical properties: acetaminophen, and propionic, acetic, salicylic, fenamic and enolic acids. RESULTS: A total of 170 SCARs, consisting of 85 SJS, 32 TEN, 17 SJS-TEN overlap syndrome and 36 DRESS reactions, were induced by NSAIDs: propionic acids (n=68), acetaminophen (n=38), acetic acids (n=23), salicylic acids (n=16), coxibs (n=8), fenamic acids (n=7), enolic acids (n=5) and unclassified (n=5). Acetic acids (22%) and coxibs (14%) accounted for higher portions of DRESS than other SCARs. The phenotypes of SCARs induced by both propionic and salicylic acids were similar (SJS, TEN and DRESS, in order). Acetaminophen was primarily associated with SJS (27%) and was less involved in TEN (10%). DRESS occurred more readily among subjects experiencing coxib-induced SCARs than other NSAID-induced SCARs (62.5% vs. 19.7%, P = 0.013). The mean time to symptom onset was longer in DRESS than in SJS or TEN (19.1 ± 4.1 vs. 6.8 ±1.5 vs. 12.1 ± 3.8 days). SCARs caused by propionic salicylic acids showed longer latency, whereas acetaminophen- and acetic acid-induced SCARs appeared within shorter intervals. CONCLUSIONS: The present study indicates that the phenotypes of SCARs may differ according to the chemical classifications of NSAIDs. To establish the mechanisms and incidences of NSAID-induced SCARs, further prospective studies are needed.

RESUMO

Albizzia julibrissin (AJ) is an herbal medicine that shows low toxicity, promotes promoting blood circulation and mitigates the inflammation and has mild side effects. Benign prostate hyperplasia (BPH) is one of the most common diseases that occurs in older males and often results in lower urinary tract symptoms. This study was conducted to evaluate the protective effect of AJ against BPH using LNCaP cells and Sprague Dawley rats treated with testosterone. Treatment with AJ extract reduced the expression of androgen receptor (AR) and prostate-specific antigen (PSA) in vitro. In vivo, rats were divided into 6 groups: 1 (Normal Control); 2 (Testosterone propionate (TP) alone); 3 (TP + finasteride); 4 (TP + AJ 10 mg/kg); 5 (TP + AJ 50 mg/kg); 6 (TP + AJ 300 mg/kg). The groups treated with AJ showed reduced the relative prostate weights and BPH-related proteins were altered, with decreased AR, PSA and proliferating cell nuclear antigen (PCNA) observed by western blot. Histopathological analysis revealed the therapeutic effect of AJ, with a decreased thickness of epithelial cells and reduced level of PCNA and 5α-reductase type 2. These results suggest that AJ extract could ameliorate testosterone-induced benign prostatic hyperplasia.

RESUMO

Preclinical Research & Development Current drugs for obesity treatment have limited efficacy and considerable adverse effects. Combination of drugs with complementary mechanisms of action at lower doses may produce a greater efficacy with a better safety profile. This study was designed to assess the anorectic effect and safety of a diethylpropion + topiramate mixture in rats. The anorectic effect of drugs was measured using a sweetened milk consumption model, and the corresponding interaction was determined by isobolographic analysis, interaction index and confidence intervals. Additionally, blood pressure was measured using a sphygmomanometer in the rat tail. Diethylpropion and topiramate alone or in combination increased the anorectic effect in a dose-dependent fashion in either nondeprived or 12 hr food-deprived rats. All theoretical ED30 values of diethylpropion + topiramate combinations at 1:1, 1:3, and 3:1 dose ratios were significantly higher than experimental ED30 values. In addition, interaction indices and confidence intervals confirmed the potentiation between both drugs. Theoretical ED30 of diethylpropion + topiramate combination did not affect the blood pressure. Data suggests that low doses of the diethylpropion + topiramate combination can potentiate the anorectic effect of individual drugs with a better safety profile, which deserves further investigation in clinical trials.

RESUMO

BACKGROUND: Adverse cutaneous drug reactions (ACDRs) are common and are responsible for increased morbidity, mortality, and socioeconomic costs. OBJECTIVE: The purpose of our study was to investigate the common drugs and clinical patterns related to ACDRs using an electronic drug adverse reaction reporting system at a single secondary referral center. METHODS: We conducted a retrospective analysis of the ACDR database between January 2014 and April 2016 at the Ilsan Paik Hospital. RESULTS: The study analyzed 320 patients with ACDRs (male:female ratio=93:227; mean age 50.8±17.8 years). Using a Korean causality evaluation algorithm, the percentage of drugs with a possible relationship with ACDRs was calculated to be 50.6%, while the percentage with a probable relationship was 44.7%. Antibiotics (44.0%), radiocontrast media (15.1%), and non-steroidal anti-inflammatory drugs (NSAIDs) (14.3%) were the most commonly implicated drugs. Antibiotics, including cephalosporins (30.6%) and quinolones (10.2%), were responsible for the majority of the ACDRs. Acetic acid (5.9%) and propionic acid (5.9%) derivatives of NSAIDs were also common causative agents. The most common clinical presentations were maculopapular exanthema (33.4%), pruritus (30.9%), and urticaria (25.7%). Severe ACDRs were significantly associated with older age, eosinophilia, and underlying heart and renal diseases (p<0.05). CONCLUSION: Antibiotics, radiocontrast media, and NSAIDs were identified as common causes of ACDRs. Older age, eosinophilia, heart disease, and renal disease were associated with severe ACDRs.

RESUMO

The aim of this study was to evaluate efficacy and safety of amfepramone, fenproporex and mazindol as a monotherapy for the treatment of obese or overweight patients. A systematic review of primary studies was conducted, followed by a direct meta-analysis (random effect) and mixed treatment comparison. Medline and other databases were searched. Heterogeneity was explored through I2 associated with a p-value. Of 739 identified publications, 25 were included in the meta-analysis. The global evaluation of Cochrane resulted in 19 studies with a high level of bias and six with unclear risk. Due to the lack of information in primary studies, direct meta-analyses were conducted only for amfepramone and mazindol. Compared to placebo, amfepramone resulted in higher weight loss in the short-term (<180 days; mean difference (MD) -1.281 kg; p<0.05; I2: 0.0%; p=0.379) and long-term (≥180 days; MD -6.518 kg; p<0.05; I2: 0.0%; p=0.719). Only studies with long-term follow up reported efficacy in terms of abdominal circumference and 5-10% weight reduction. These results corroborated the finding that the efficacy of amfepramone is greater than that of placebo. Treatment with mazindol showed greater short-term weight loss than that with placebo (MD -1.721 kg; p<0.05; I2: 0.9%; p=0.388). However, metabolic outcomes were poorly described, preventing a meta-analysis. A mixed treatment comparison corroborated the direct meta-analysis. Considering the high level of risk of bias and the absence of important published outcomes for anti-obesity therapy assessments, this study found that the evaluated drugs showed poor evidence of efficacy in the treatment of overweight and obese patients. Robust safety data were not identified to suggest changes in their regulatory status.

RESUMO

Antiobesity pharmacotherapy remains the main point of disagreement among both scientists and regulators. This is probably due to small sample sizes, high levels of heterogeneity, and low methodological quality. For many years, Brazil was one of the largest consumers of appetite suppressants worldwide, with evidence of irrational use of this drug class. Therefore, the country was the scene of a debate that divided the Brazilian Health Surveillance Agency (Anvisa - Agência Nacional de Vigilância Sanitária) and medical societies over the maintenance record of diethylpropion, mazindol and fenproporex. In this context, this commentary presents new arguments to contribute to the discussion, as well as recommendations for future studies.

RESUMO

PURPOSE: Most of the atopic dermatitis (AD) patients and their parents refuse topical treatment because of concern about generalized side effect due to systemic absorption of topical corticosteroids. Therefore, a large number of studies reported difficulty in properly controlling in AD. However, investigations of the percutaneous absorption of topical corticosteroids are still insufficient. METHODS: One hundred nine patients who visited our atopy clinic and diagnosed as AD by a physician from January 2005 to January 2012 were enrolled. We examined serum corticosteroid (clobetasol propionate, hydrocortisone) level by liquid chromatography (LC) coupled with a tandem mass spectrometric (MS/MS) method. RESULTS: We developed the LC-MS/MS method to determine corticosteroids (clobetasol propionate, hydrocortisone) in sera of AD patients. Also, we confirmed precision, accuracy, limit of detection, limit of quantification, absolute recovery, and relative recovery of the experimental methods. We could not detect clobetasol propionate or hydrocortisone in sera of 109 AD patients using the newly developed LC-MS/MS method. CONCLUSION: Regardless of age, the severity and illness duration of AD, clobetasol and hydrocortisone were not detected in sera. Although there are many other factors of determining systemic absorption of topical medications, our results showed that topical corticosteroids applied for several years in AD patients may be under the limit of detection in their sera by the LC-MS/MS method.

RESUMO

PURPOSE: Extrafine-particle inhaled corticosteroids (ICS) have greater small airway deposition than standard fine-particle ICS. We sought to compare asthma-related outcomes after patients initiated extrafine-particle ciclesonide or fine-particle ICS (fluticasone propionate or non-extrafine beclomethasone). METHODS: This historical, matched cohort study included patients aged 12-60 years prescribed their first ICS as ciclesonide or fine-particle ICS. The 2 cohorts were matched 1:1 for key demographic and clinical characteristics over the baseline year. Co-primary endpoints were 1-year severe exacerbation rates, risk-domain asthma control, and overall asthma control; secondary endpoints included therapy change. RESULTS: Each cohort included 1,244 patients (median age 45 years; 65% women). Patients in the ciclesonide cohort were comparable to those in the fine-particle ICS cohort apart from higher baseline prevalence of hospitalization, gastroesophageal reflux disease, and rhinitis. Median (interquartile range) prescribed doses of ciclesonide and fine-particle ICS were 160 (160-160) µg/day and 500 (250-500) µg/day, respectively (P<0.001). During the outcome year, patients prescribed ciclesonide experienced lower severe exacerbation rates (adjusted rate ratio [95% CI], 0.69 [0.53-0.89]), and higher odds of risk-domain asthma control (adjusted odds ratio [95% CI], 1.62 [1.27-2.06]) and of overall asthma control (2.08 [1.68-2.57]) than those prescribed fine-particle ICS. The odds of therapy change were 0.70 (0.59-0.83) with ciclesonide. CONCLUSIONS: In this matched cohort analysis, we observed that initiation of ICS with ciclesonide was associated with better 1-year asthma outcomes and fewer changes to therapy, despite data suggesting more difficult-to-control asthma. The median prescribed dose of ciclesonide was one-third that of fine-particle ICS.

RESUMO

Treatment for pulmonary arterial hypertension (PAH) has been underpinned by single-agent therapy to which concomitant drugs are added sequentially when pre-defined treatment goals are not met.This retrospective analysis of real-world clinical data in 97 patients with newly diagnosed PAH (86% in New York Heart Association functional class III-IV) explored initial dual oral combination treatment with bosentan plus sildenafil (n=61), bosentan plus tadalafil (n=17), ambrisentan plus tadalafil (n=11) or ambrisentan plus sildenafil (n=8).All regimens were associated with significant improvements in functional class, exercise capacity, dyspnoea and haemodynamic indices after 4 months of therapy. Over a median follow-up period of 30 months, 75 (82%) patients were still alive, 53 (71%) of whom received only dual oral combination therapy. Overall survival rates were 97%, 94% and 83% at 1, 2 and 3 years, respectively, and 96%, 94% and 84%, respectively, for the patients with idiopathic PAH, heritable PAH and anorexigen-induced PAH. Expected survival rates calculated from the French equation for the latter were 86%, 75% and 66% at 1, 2 and 3 years, respectively.Initial combination of oral PAH-targeted medications may offer clinical benefits, especially in PAH patients with severe haemodynamic impairment.

RESUMO

Obesity is a public health problem caused by excessive consumption of high caloric diets and/or lack of physical activity. Although treatments for obesity include low caloric diets and exercise programs, these activities frequently are supplemented with appetite suppressants. For the short-term treatment of weight loss, diethylpropion (DEP) is a commonly used appetite suppressant. However, little is known with regard to how to improve its weight loss efficacy. We therefore evaluated, in rats, two administration protocols where the animals received daily injections of DEP. First, when these nocturnal animals were normally active (at night) and when they were normally inactive (daytime), and second, with or without high fat dietary restriction (HFDR). We observed that DEP induced a greater weight-loss administered when the animals were in their active phase than in their inactive phase. Moreover, DEP's administration during the inactive phase (and to a lesser degree in the active phase) promotes the consumption of food during normal sleeping time. In addition, we found that DEP-induced weight loss under ad libitum access to a HF diet, but its efficacy significantly improved under conditions of HFDR. In summary, the efficacy of DEP, and presumably other like appetite suppressants, is enhanced by carefully controlling the time it is administered and under dietary restriction of HF diets.

RESUMO

PURPOSE: No studies have been conducted to investigate the acute toxicity of aryloxyphenoxypropionate herbicides in humans following ingestion. Therefore, this study was conducted to investigate the clinical characteristics of aryloxyphenoxypropionate herbicide poisoning and provide guidance for physicians treating patients who have ingested these types of herbicides. METHODS: A retrospective observational case series was conducted using ten patients with history of aryloxyphenoxy propionate herbicide. Data were collected for clinical manifestation, management and final outcome. RESULTS: The most common symptoms were gastrointestinal irritation and an altered mental state (Glasgow Coma Scale<15). An elevated lactate level was a common laboratory abnormality, and prolonged QTc interval was commonly observed. These clinical features normalized within one day of supportive treatment. CONCLUSION: The acute toxicity of aryloxyphenoxypropionate herbicides in humans is manageable with supportive treatment. However, physicians should take into account depressed consciousness, the possibility of arrhythmia, and an elevated lactate level when planning their treatment strategy.

RESUMO

Amfepramone, also known as diethylpropion, is an anorectic drug used for the short-term treatment of obesity; however, its efficacy and safety during periods greater than 3 months has been scarcely studied. To evaluate the 6-month efficacy and safety of amfepramone treatment in obese adult Mexican patients resistant to diet and exercise, a double-blinded, randomized, and placebo-controlled clinical trial study was designed on 156 volunteers with a body mass index (BMI) greater than 30 kg/m2 and less than 45 kg/m2. Patients were randomized to receive a 75 mg tablet of amfepramone or placebo daily for 6 months. Primary outcome was the absolute body weight loss, whereas secondary outcomes were the percentage of patients who achieved at least 5% or 10% weight loss, as well as the improvement of anthropometric and metabolic parameters. Amfepramone treatment produced a superior efficacy to decrease body weight than placebo at 3 months (-4.9±0.25 kg vs. -0.7±0.32 kg) and 6 months (-7.7±0.52 kg vs. -1.1±0.7 kg). In addition, 64 and 34 patients achieved at least 5% or 10% weight loss, respectively, with amfepramone at 6 months, compared with 8 and 0 patients on placebo. Amfepramone also significantly improved BMI and waist circumference, but it only showed a favorable tendency in the waist-hip index (WHI), glucose, total cholesterol, low-density lipoproteins (LDL), high-density lipoproteins (HDL), triglycerides, heart rate, systolic blood pressure, and diastolic blood pressure at 3 and 6 months. Amfepramone produced only mild adverse events, and they were presented in a greater number than placebo only at 3 months, dry mouth being the the main adverse event. Data suggest that amfepramone is effective and well tolerated in obese Mexican patients during a 6-month regimen.
