The Efficacy of Different Triptans for the Treatment of Acute Headache in Pediatric Migraine: A Systematic Review

Background: Serotonin receptors 5-HT1B and 5-HT1D in the cerebral arteries are activated by the 5-hydroxytryptophan agonists (triptans) to relieve the discomfort associated with migraines. Even though triptans are often used to treat acute migraines, there is some debate over their effectiveness. Objective: Our systematic review aimed to evaluate the effectiveness of triptans for acute treatment of migraine in young individuals. Methods: Utilizing the databases of Google Scholar, Cochrane Library, and PubMed, a literature search was conducted, and all papers published till July 2022 were included. This systematic review was carried out following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards. In addition to the Boolean operators AND, OR, and NOT, the following descriptive terms were also used: “Triptans,” “Pediatric Migraine,” “Migraine disorders,” “Headache,” “Children,” and “Adolescent.” Results: A total of 1047 studies were identified, and 25 articles were finally included in the study. 17 of them were RCTs while the remaining were non-randomized trials. Most studies recruited participants aged between 12-17 years. Among 25 studies, 7 reported sumatriptan use, 3 assessed a combination of sumatriptan and naproxen, 4 were on almotriptan, 1 on eletriptan, 6 on rizatriptan, and 4 on zolmitriptan use. Conclusion: We found that rizatriptan (good tolerability profile with a dose of 5 mg) and sumatriptan (nasal spray, 10 mg and 20 mg) had higher efficiency as compared to other triptans. Regardless of type or dose, all triptans are generally well tolerated by patients, but a few adverse effects such as light-headedness (sumatriptan), nasopharyngitis, and, muscular spasms (sumatriptan/ naproxen), somnolence, and dry mouth (rizatriptan), and dizziness (zolmitriptan group) were reported with the triptans.

Enfermedad renal diabética: pilares en el tratamiento / Diabetic kidney disease: pillars in treatment

Introducción: La diabetes mellitus (DM) es una enfermedad crónica inflamatoria muy frecuente y por ende una de las emergencias sanitarias mundiales de más rápido crecimiento en las últimas décadas. Hay tres ejes que impactan en la progresión del compromiso renal del paciente diabético. El eje hemodinámico, metabólico e inflamatorio. Resaltamos la importancia del componente inflamatorio como actor protagónico en el desarrollo de la Enfermedad renal diabética (ERD). El manejo del paciente con ERD debe ser holístico, con tres objetivos claros: buen control metabólico, disminuir progresión de la enfermedad renal y disminuir los desenlaces cardiovasculares adversos. Actualmente además de las intervenciones no farmacológicas, el control de los factores de riesgo, el uso de los IECAS/ARA II hay nuevos pilares en el tratamiento de la ERD. Objetivos: El objetivo de esta comunicación es revisar los nuevos pilares en el manejo de la ERD. En la revisión bibliográfica que se hizo, encontramos que hay tres nuevos pilares en el tratamiento. Los inhibidores SGLT-2, los agonistas del receptor GLP-1 y por último finerenona, que es un antagonista selectivo no esteroideo del receptor mineralocorticoide (ARM), no es un antidiabético. Con estas nuevas terapias el manejo actual de estos pacientes ha cambiado considerablemente. Conclusión: Hay nuevos pilares en el tratamiento de la ERD. Los inhibidores SGLT-2, los Agonistas del receptor GLP-1 y el uso de ARM como finerenona, que nos brindan beneficios cardio­renales y que hacen que hoy en día el tratamiento de la ERD tenga un mejor panorama.

Introduction: Diabetes mellitus (DM) is a very common chronic inflammatory disease and finally one of the fastest-growing global health emergencies in recent decades. Three axes impact the progression of renal compromise in diabetic patients. The hemodynamic, metabolic, and inflammatory axis. We highlight the importance of the inflammatory component as a leading actor in developing Diabetic Kidney Disease (DKD). The management of the patient with CKD must be holistic, with three clear objectives: reasonable metabolic control, slowing the progression of kidney disease, and reducing adverse cardiovascular outcomes. Currently, in addition to non-pharmacological interventions, the control of risk factors, and the use of ACE inhibitors/ARA II, there are new pillars in the treatment of CKD. Objectives: The objective of this communication is to review the new pillars in the management of DKD. In the bibliographic review that was carried out, we found that there are three new pillars in the treatment. SGLT-2 inhibitors, GLP-1 receptor agonists, and finally finerenone, which is a selective non-steroidal antagonist of the mineralocorticoid receptor (MRA), not an antidiabetic. With these new therapies, the current management of these patients has changed considerably. Conclusion: There are new pillars in the treatment of DKD. The SGLT-2 inhibitors, the GLP-1 receptor agonists, and the use of MRAs such as finerenone provide us with cardio-renal benefits and which today make the treatment of CKD have a better outlook.

Research progress on analgesic effect and adverse drug reactions of opioid receptor agonist-antagonists / 中国药房

Opioid receptor agonist-antagonists are a class of drugs which have both agonistic and antagonistic effects on opioid receptors. These drugs already on the market mainly include pentazocine， butorphanol， nalbuphine， buprenorphine， dezocine and so on. Compared with pure opioid receptor agonists such as morphine and fentanyl， these drugs have strong analgesic effects， less addictive， and less side effects such as cough， itching and respiratory depression. Due to the different tendentious effects of opioid receptor agonists-antagonists among different endogenous opioid receptors （μ， κ， δ， etc.）， different receptors of subtypes can exhibit different or even opposite effects in terms of affecting emotions and drug dependence. Therefore， the rational use of these drugs can effectively reduce the occurrence of adverse reactions and drug abuse caused by opioid drugs. With the deepening of research on various endogenous opioid receptor subtypes and related drugs in the academic community， opioid receptor agonists- antagonists have broad application space and prospects in improving adverse reactions to opioid drugs and enhancing patient drug compliance.

Effects of ADRB2 gene regulatory region polymorphism on the efficacy of SABA in the treatment of acute asthma attack in children / 中国药房

OBJECTIVE To explore the effects of ADRB2 gene regulatory region polymorphism on the efficacy of short-acting beta 2 receptor agonists （SABA） in the treatment of acute asthma attack in children. METHODS A total of 127 children with acute mild to moderate bronchial asthma who received SABA treatment for 7 days in the General Hospital of Northern Theater Command from October 2016 to October 2020 were selected to detect their genotype distribution and compare the improvement of pulmonary functional indicators and curative effect among different genotypes. The effect of the high-order interaction of gene polymorphism on therapeutic effect was investigated. RESULTS Among 127 children， there were 80， 44 and 3 cases of TT， TA and AA types at locus rs2895795， 93， 32 and 2 cases of CC， CG and GG types at locus rs11168070， and 41， 64 and 22 cases of GG， GA and AA types at locus rs12654778， respectively， in accordance with Hardy-Weinberg equilibrium （P＞0.05）. After treatment， the improvement rate of the peak expiratory flow in percent predicted value （PEF%pred） and the improvement rate of the forced expiratory flow at 75% vital capacity in percent predicted value （FEF75%pred） in children with TA type were significantly lower than that of TT type at locus rs2895795 （P＜0.05）； the improvement rates of PEF%pred and FEF75%pred in children with CG type were significantly lower than that of CC type at locus rs11168070 （P＜0.05）； the improvement rates of PEF%pred in children with GA and AA type were significantly lower than that of GG type at locus rs12654778 （P＜0.05）. The differences in fractional exhaled nitric oxide before and after treatment were not statistically significant among different genotypes at each locus （P＞0.05）. The proportion of remarkable improvement of children with TT type at locus rs2895795 was 2.358 times that of children with TA+ AA type （P＜0.05）， and there was no significant effect of higher-order interaction of ADRB2 polymorphism on the efficacy in children with asthma （P＞0.05）. CONCLUSIONS Polymorphisms in the regulatory region of the ADRB2 gene in children with bronchial asthma are associated with the efficacy of SABA in the treatment of acute asthma attack in children. At locus rs2895795， rs11168070 and rs12654778， the improvement of lung function of children with wild-type is more obvious， and the efficacy of SABA treatment on children with TT type is better at locus rs2895795.

Opportunities and challenges of incretin-based hypoglycemic agents treating type 2 diabetes mellitus from the perspective of physiological disposition

The treatment of patients with diabetes mellitus, which is characterized by defective insulin secretion and/or the inability of tissues to respond to insulin, has been studied for decades. Many studies have focused on the use of incretin-based hypoglycemic agents in treating type 2 diabetes mellitus (T2DM). These drugs are classified as GLP-1 receptor agonists, which mimic the function of GLP-1, and DPP-4 inhibitors, which avoid GLP-1 degradation. Many incretin-based hypoglycemic agents have been approved and are widely used, and their physiological disposition and structural characteristics are crucial in the discovery of more effective drugs and provide guidance for clinical treatment of T2DM. Here, we summarize the functional mechanisms and other information of the drugs that are currently approved or under research for T2DM treatment. In addition, their physiological disposition, including metabolism, excretion, and potential drug-drug interactions, is thoroughly reviewed. We also discuss similarities and differences in metabolism and excretion between GLP-1 receptor agonists and DPP-4 inhibitors. This review may facilitate clinical decision making based on patients' physical conditions and the avoidance of drug-drug interactions. Moreover, the identification and development of novel drugs with appropriate physiological dispositions might be inspired.

The cannabinoids mechanism of action: an overview / Mecanismo de ação dos canabinoides: visão geral

ABSTRACT BACKGROUND AND OBJECTIVES: The discovery of the psychoactive agent of Cannabis sativa (tetrahydrocannabinol - THC) in the second half of the 20th century originated the research that later came to identify dozens of other substances from this plant, including cannabinoids, terpenes and flavonoids. Ensuing description of their interaction sites in animals and humans, together with endogenous ligands, transport proteins as well as synthesis and degradation enzymes, revealed what came to be known as the endocannabinoid system. Several receptors participate in this system. CONTENTS: The first receptors to be discovered were called CB1 and CB2, both are G protein-coupled (GPCR). It is noteworthy that CB1 receptors are among the most abundant and widely distributed GPCR in the mammalian brain, with marked expression in basal ganglia, cerebellum and hippocampus, for instance; on the other hand, they are scarce in areas of the brainstem related to breathing control. In light of the multiplicity of pharmacological effects of cannabinoids, concomitant with the lack of more clarifying studies on their mechanisms of action despite the great interest in research on their therapeutic application, it is necessary to deepen the knowledge in this area. CONCLUSION: Considering the literature research conducted for the composition of this article, it is possible to conclude that cannabinoids have a broad spectrum of action mechanisms in the human body, and that more robust clinical studies are needed to better understand their broad therapeutic potential.

RESUMO JUSTIFICATIVA E OBJETIVOS: A descoberta do princípio psicoativo da Cannabis sativa (tetrahidrocanabinol - THC) na segunda metade do século XX inaugurou pesquisas que posteriormente vieram a identificar dezenas de outras substâncias a partir dessa planta, incluindo canabinoides, terpenos e flavonoides. A subsequente descrição dos sítios de interação dessas substâncias em animais e humanos, assim como seus ligantes endógenos, proteínas de transporte e enzimas de síntese e degradação, revelou o que veio a ser conhecido como sistema endocanabinoide. Diversos receptores participam deste sistema. CONTEÚDO: Os primeiros receptores a serem descobertos foram denominados CB1 e CB2, ambos são acoplados à proteína G (GPCR). É importante ressaltar que os receptores CB1 estão entre os GPCRs mais abundantes e amplamente distribuídos do encéfalo de mamíferos, com marcada expressão, por exemplo, em gânglios da base, cerebelo e hipocampo; em contrapartida, são escassos em áreas do tronco cerebral relacionadas ao controle da respiração. Diante da multiplicidade de efeitos farmacológicos dos canabinoides, concomitante à falta de estudos mais esclarecedores sobre seus mecanismos de ação apesar do grande interesse na pesquisa de sua aplicação terapêutica, é preciso aprofundar o conhecimento nessa área. CONCLUSÃO: Considerando as pesquisas bibliográficas realizadas para a composição deste artigo, é possível concluir que os canabinoides possuem um amplo espectro de mecanismos de ação no organismo humano, e que mais estudos clínicos robustos são necessários para que seja possível entender melhor o seu amplo potencial terapêutico.

Glucagon-like peptide-1 receptor agonists and glycemic management in non-critical hospitalized patients / 中华内分泌代谢杂志

In recent years, with the continuous development of glucagon-like peptide-1 receptor agonists(GLP-1RA), its role in the management of blood glucose in hospitalized patients has been explored. GLP-1RA can not only control blood glucose in non-critically ill hospitalized patients, but also inhibit appetite, delay gastric emptying, protect nerves, anti-inflammation, reduce systolic blood pressure and blood lipids. At the same time, many studies have found that it can also improve cardiovascular and renal outcomes and reduce the risk of hospitalization complications. Therefore, this paper analyzes the role of GLP-1RA in glycemic management by reviewing domestic and international studies, consensus and guidelines related to inpatient blood glucose management, and helps to better manage blood glucose of patients in non-critical care setting.

Efectos renales de los agonistas GLP-1 en la diabetes tipo 2 / Renal effects of GLP-1 agonists in type 2 diabetes

Resumen La prevalencia de diabetes mellitus tipo 2 (DM2) está en aumento, generando un gran impacto tanto a nivel individual como en salud pública. Cerca de la mitad de los pacientes con DM2 sufren un deterioro de la función renal, por esto la nefroprotección resulta de fundamental importancia. El conjunto de evidencia que cambió del enfoque terapéutico glucocéntrico al cardiorrenometabólico en la DM2 motivó la inclu sión en las recomendaciones internacionales de nuevas terapias con beneficios cardiovasculares y renales. Los agonistas del receptor del péptido similar al glucagón tipo 1 (GLP-1) tienen efectos favorables sobre la función renal y sus posibles acciones protectoras son multifactoriales, más allá del control glucémico. Estos beneficios han sido demostrados en los estudios clínicos de eficacia y seguridad, así como también en los estudios de re sultados cardiovasculares y de vida real. En esta revisión narrativa se describen los efectos directos e indirectos de estas moléculas, así como su evidencia en los principales estudios clínicos (LEADER, SUSTAIN 6 y REWIND) y de vida real que demuestran sus efectos beneficiosos sobre la función renal e introduce la expectativa de los resultados futuros de los estudios en curso con objetivos renales.

Abstract The prevalence of type 2 diabetes mellitus (DM2) is increasing, generating a great impact both at individual and public health level. Nearly half of the patients with DM2 develop impaired renal function, so nephron-protection is highly important. The robust body of evidence that shifted the therapeutic focus from glycemic to cardio-renal metabolic therapy in DM2 led to the inclusion of new therapies with cardiovascular and renal benefits in international guidelines. Type 1 glucagon (GLP-1) receptor agonists have showed favorable effects on renal function and their potential protective actions are multifactorial, beyond glycemic control. These benefits have been demonstrated in efficacy and safety clini cal studies, as well as in cardiovascular outcomes and real-life studies. This comprehensive review describes the direct and indirect effects of these molecules, as well as evidence obtained from pivotal clinical (LEADER, SUSTAIN 6 and REWIND) and real-life studies demonstrating their beneficial effects on renal function, and also introduces expectations of future results from ongoing studies with renal endpoints.

Reporte de un caso de tratamiento de gastroparesia pediátrica con prucaloprida: una terapia novedosa / A case report of prucalopride treatment in pediatric gastroparesis: a novel therapy

La prucaloprida acelera el vaciamiento gástrico en adultos con gastroparesia. No existen estudios con este medicamento en niños con gastroparesia. Se presenta un niño de 8 años que consultó por síntomas posprandiales de un mes de duración, con diagnóstico de gastroparesia por gammagrafía de vaciamiento gástrico. No mejoró con metoclopramida, domperidona, eritromicina y esomeprazol. Recibió prucaloprida durante dos períodos (durante 178 y 376 días) a dosis de 0,03-0,04 mg/kg/día. Presentó mejoría en el seguimiento con el índice cardinal de síntomas de gastroparesia y gammagrafías de vaciamiento gástrico. Por la buena respuesta, la prucaloprida podría ser una opción terapéutica en la gastroparesia pediátrica.

Prucalopride has been used in adults with gastroparesis, accelerating gastric emptying. There are no studies with this drug in gastroparetic children. An 8-year-old boy is presented who consulted for a month of postprandial symptoms, with a diagnosis of gastroparesis by gastric emptying scintigraphy. He did not improve with metoclopramide, domperidone, erythromycin, and esomeprazole. He received prucalopride for two periods (for 178 and 376 days) at doses: 0.03 - 0.04 mg/kg/day, presenting improvement in the follow-up with the cardinal gastroparesis symptom index and gastric emptying scintigraphy. Due to the good response, prucalopride may be a therapeutic option in pediatric gastroparesis.

Endogenous and exogenous serotonin, but not sumatriptan, ameliorate seizures and neuroinflammation in the pentylenetetrazole-induced seizure model in rats / A serotonina endógena e exógena, mas não o sumatriptano, melhora as convulsões e a neuroinflamação no modelo de convulsão induzida por pentilenotetrazol em ratos

ABSTRACT Background: Epilepsy has neuropsychiatric comorbidities such as depression, bipolar disorder, and anxiety. Drugs that target epilepsy may also be useful for its neuropsychiatric comorbidities. Objective: To investigate the effects of serotonergic modulation on pro-inflammatory cytokines and the seizures in pentylenetetrazole (PTZ)-induced seizure model in rats. Methods: Male Wistar rats were injected intraperitoneally with serotonin, selective serotonin reuptake inhibitor fluoxetine, 5-HT1B/D receptor agonist sumatriptan, or saline 30 min prior to PTZ treatment. Behavioral seizures were assessed by the Racine's scale. Concentrations of IL-1β, IL-6, and TNF-α in serum and brain tissue were determined by ELISA. Results: Serotonin and fluoxetine, but not sumatriptan, alleviated PTZ-induced seizures by prolonging onset times of myoclonic-jerk and generalized tonic-clonic seizures. The anti-seizure effect of fluoxetine was greater than that of serotonin. Likewise, serotonin and fluoxetine, but not sumatriptan, reduced PTZ-induced increases in the levels of IL-1β and IL-6 in both serum and brain tissue. None of the administered drugs including PTZ affected TNF-α concentrations. Conclusions: Our findings suggest that endogenous and exogenous serotonin exhibits anticonvulsant effects by suppressing the neuroinflammation. It seems that 5-HT1B/D receptors do not mediate anticonvulsant and anti-neuroinflammatory effects of serotonin.

RESUMO Antecedentes: A epilepsia apresenta comorbidades neuropsiquiátricas como depressão, transtorno bipolar e ansiedade. Os medicamentos que visam o tratamento da epilepsia podem ser úteis para a epilepsia e suas comorbidades neuropsiquiátricas. Objetivo: Investigar os efeitos da modulação serotonérgica em citocinas pró-inflamatórias e as convulsões no modelo de convulsão induzida por pentilenotetrazol (PTZ) em ratos. Métodos: Ratos Wistar machos foram injetados intraperitonealmente com serotonina, inibidor seletivo da recaptação da serotonina fluoxetina, sumatriptano agonista do receptor 5-HT1B / D ou solução salina 30 min antes do tratamento com PTZ. As crises comportamentais foram avaliadas pela escala de Racine. As concentrações de IL-1β, IL-6 e TNF-α no soro e tecido cerebral foram determinadas por ELISA. Resultados: A serotonina e a fluoxetina, mas não o sumatriptano, aliviaram as convulsões induzidas por PTZ ao prolongar os tempos de início das convulsões mioclônicas e tônico-clônicas generalizadas. O efeito anticonvulsivo da fluoxetina foi maior do que o da serotonina. Da mesma forma, a serotonina e a fluoxetina, mas não o sumatriptano, reduziram os aumentos induzidos por PTZ nos níveis de IL-1β e IL-6 no soro e no tecido cerebral. Nenhum dos medicamentos administrados, incluindo PTZ, alterou as concentrações de TNF-α. Conclusões: Nossos achados sugerem que a serotonina endógena e exógena exibe efeitos anticonvulsivantes por suprimir a neuroinflamação. Aparentemente, os receptores 5-HT1B / D não medeiam os efeitos anticonvulsivantes e anti-neuroinflamatórios da serotonina.

Efficacy of inhalation therapy with montelukast sodium, budesonide and formoterol in combination in the treatment of bronchial asthma in adult patients and its effects on cytokines / 中国基层医药

Objective:To investigate the efficacy of combination treatment with montelukast sodium, budesonide and formoterol in the treatment of bronchial asthma in adults and its effects on cytokines.Methods:A total of 100 adult patients with bronchial asthma who received treatment in The First People's Hospital of Yongkang from January 2019 to December 2020 were included in this study. They were randomly assigned to receive either budesonide inhalation alone (control group, n = 50) or combination inhalation of montelukast sodium, budesonide and formoterol (observation group, n = 50) for 12 weeks. Efficacy was compared between the two groups. Lung function [forced expiratory volume in one second (FEV 1), peak expiratory flow (PEF) and FEV 1/forced vital capacity (FVC) ratio], cytokines [interleukin (IL)-2, IL-4, IL-6], Asthma Quality of Life Questionnaire (AQLQ) score, and Asthma Control Test (ACT) score measured before and 12 weeks after treatment were compared between the two groups. Results:Total response rate in the observation group was significantly higher than that in the control group [92.00% (46/50) vs. 72.00% (36/50), χ2 = 6.77, P < 0.05). After 12 weeks of treatment, FEV 1, PEF and FEV1/FVC in the observation group were (2.17 ± 0.23) L, (246.56 ± 17.86) L/s, and (83.86 ± 3.98)%, respectively, which were significantly higher than (1.86 ± 0.17) L, (203.12 ± 20.10) L/s, (74.82 ± 5.67)% in the control group ( t = 7.66, 11.42, 9.22, P < 0.05). Serum IL-2 level in the observation group was significantly higher than that in the control group [(10.85 ± 0.86) ng/L vs. (8.94 ± 1.03) ng/L, t = 10.06, t < 0.05]. Serum IL-4 and IL-6 in the observation group were (24.98 ± 3.08) ng/L and (98.46 ± 9.76) μg/L, respectively, which were significantly lower than (36.75 ± 4.34) ng/L and (125.84 ± 13.19) μg/L in the control group ( t =15.63, 11.79, both P < 0.05). AQLQ score and ACT score in the observation group were (121.03 ± 8.69) points and (22.08 ± 1.35) points, respectively, which were significantly higher than (110.93 ± 7.86) points and (19.74 ± 1.76) points in the control group ( t = 6.095, 7.460, both P < 0.05). Conclusion:Inhalation therapy with montelukast sodium, budesonide and formoterol produces obvious therapeutic effects on bronchial asthma in adult patients and the combined therapy can reduce inflammatory reactions.

Non-alcoholic fatty liver disease: Epidemiology, pathophysiology and an update on the therapeutic approaches

Non-alcoholic fatty liver disease (NAFLD) denotes a spectrum of fatty liver disease in individuals without significant alcohol consumption. NAFLD is set to be the most common etiology of serious liver diseases in numerous nations when accompanied by obesity and type 2 diabetes. It is further histologically categorized into the non-alcoholic fatty liver (NAFL; steatosis without hepatocellular injury) and non-alcoholic steatohepatitis (NASH) which is characterized by the coexistence of hepatic steatosis and inflammation and is accompanied by hepatocyte injury (ballooning), either with or without fibrosis. NAFL is considered the benign and reversible stage arising from the excessive accumulation of triglycerides in hepatocytes. However, NASH is a more progressive stage of NAFLD, due to the increased risks of evolving more serious diseases such as cirrhosis, hepatocellular carcinoma. This concept, however, has been lately challenged by a hypothesis of multiple parallel hits of NAFLD, in which steatosis and NASH are separate entities rather than two points of the NAFLD spectrum, not only from a set of histological patterns but also from a pathophysiological perspective. The current review highlights the epidemiology and pathophysiology of NAFLD, and its progression towards steatohepatitis, with special focus on the novel imminent therapeutic approaches targeting the molecular aspects and the pathogenic pathways involved in the development, and progression of NAFLD.

OBJECTIVE To mine and analyze the risk signal of glucagon- like peptide -1 receptor agonists （GLP-1RA）related adverse drug reaction （ADR）. METHODS ADR data related to GLP- 1RA from April 1，2005 to October 16，2021 in the openFDA database were collected ，and the Bayesian confidence propagation neoral network （BCPNN）method was used for data mining. ADR were classified and described by using systematic organ classification （SOC）of drug ADR terminology set in 24.0 edition of MedDRA. RESULTS & CONCLUSIONS A total of 175 719 ADR reports related to GLP- 1RA were retrieved ，with 140 ADR positive signals ，involving five drugs such as exenatide （77 027 cases of ADR and 31 ADR positive signals ），dulaglutide （45 329 cases of ADR and 26 ADR positive signals ），liraglutide （42 748 cases of ADR and 32 ADR positive signals ）， semaglutide（8 844 cases of ADR and 27 ADR positive signals ）and lixisenatide （1 771 cases of ADR and 24 ADR positive signals）. According to SOC classification ，GLP-1RA-induced ADR involved gastrointestinal system ，hepatobiliary system ，nervous system，urinary and renal system ，endocrine system ，immune system and administration site. In the gastrointestinal system ，the risk of （acute）pancreatitis was higher ，and the order of risk was liraglutide ＞exenatide＞semaglutide＞dulaglutide＞lixisenatide； ADR signal of hepatobiliary system was stronger for cholelithiasis ，and the order of risk was liraglutide ＞semaglutide＞exenatide＞ lixisenatide＞dulaglutide. In the nervous system ，the risk of taste disorder was higher ；compared with dulaglutide and lixisenatide ， liraglutide，exenatide and semaglutide were more likely to cause headache and dizziness. In urinary and renal system ， compared with exena tide，dulaglutide and lixisenatide ，liraglutide and semaglutide were more likely to cause acute renal injury. In the endocrine system ，the risk of hypoglycemia was higher ，and the order of risk was exenatide ＞liraglutide＞lixisenatide＞ semaglutide＞dulaglutide. In the immune system ，lixisenatide was more likely to develop urticaria than other drugs ，dulaglutide and liraglutide did not caused ADR signal. Among the administration sites ，the risk of ADR caused by exenatide and dulaglutide was higher，while the risk of related ADR caused by semaglutide was lower. When using GLP- 1RA clinically ，we should closely monitor the renal function and blood glucose of patients ，and pay attention to patients with sudden upper abdominal pain ；in case of relevant ADR ，timely intervention measures should be taken to ensure the safety and effectiveness of medication.

Cardiovascular benefits of SGLT-2 inhibitors and GLP-1 receptor agonists in type 2 diabetes: a systematic review and network meta-analysis / 药学实践杂志

Objective To evaluate cardiovascular benefits in patients with type 2 diabetes mellitus treated with the marketed 11 sodium-glucose co-transporter-2 (SGLT-2) inhibitors and glucagon-like polypeptide-1 (GLP-1) receptor agonism by Bayesian network meta-analysis system. Methods MEDLINE, Embase and Cochrane Library were searched from the establishment of the database to 18 July 2020. The endpoint of the study was adverse cardiovascular events. The effect measures were hazard ratios (HR) and 95% credible intervals (CI). Results Compared with placebo, empagliflozin, canagliflozin, dapagliflozin, albiglutide, dulaglutide, exenatide, liraglutide, semaglutide reduced the risk of major adverse cardiovascular events in patients with type 2 diabetes with HR and 95% CI ranging between 0.75(0.60-0.95)~0.90(0.82-0.99); The risk of heart failure was reduced by empagliflozin, canagliflozin, dapagliflozin and ertugliflozin, with HR and 95%CI ranging between 0.64(0.49-0.82)~0.74(0.65-0.85); Empagliflozin, canagliflozin, dapagliflozin, exenatide, liraglutide and oral semaglutide reduced the incidence of all-cause mortality with HR and 95%CI ranging between 0.52(0.33-0.84)~0.89(0.80-0.99); Empagliflozin, canagliflozin, liraglutide and oral semaglutide can reduce the risk of cardiovascular death events, with HR and 95% CI ranging between 0.54(0.30-0.95)~0.83(0.71-0.96) . Conclusion The order of the cardiovascular benefits of SGLT-2 inhibitors or GLP-1 receptor agonists in patients with type 2 diabetes mellitus complicated with atherosclerotic cardiovascular disease are canagliflozin (the best), empagliflozin, dulaglutide, liraglutide; for patients with type 2 diabetes and heart failure. The order of the cardiovascular benefits for patients with type 2 diabetes and heart failure are empagliflozin, canagliflozin, ertugliflozin, and dapagliflozin.

Effects of Incretin - based Therapy on High - sensitivity C - reactive Protein in Patients with Type 2 Diabetes: A Systematic Review and Meta - Analysis

ABSTRACT Background: Recently, studies had shown that incretin-based therapies could reduce the levels of pro-inflammatory markers. The data on the effects of incretin-based therapies on serum high-sensitivity C-reactive protein (hs-CRP) in type 2 diabetes (T2DM) were inconsistent. Objective: The objective of the study was to assess the effects of incretin-based therapies on hs-CRP in patients with T2DM by meta-analysis. Methods: We searched PubMed, EMBASE, the Cochrane Collaboration Library, and Web of Science to identify the eligible randomized clinical trials until August 2019. The pooled standard mean differences (SMD) were calculated by random-effects model using STATA 11.0. Results: Twenty-five studies with 28 randomized controlled trials were finally included into the meta-analysis. Meta-analysis revealed a significant reduction in hs-CRP following treatment with incretin-based regimens compared to controls (SMD = −0.452, p < 0.001). Subgroup analysis of different class of incretin-based drugs showed that therapy with both dipeptidyl peptidase 4 inhibitors (DPP-4Is, SMD = −0.338, p = 0.026) and glucagon-like peptide 1 receptor agonists (GLP-1 RAs, SMD = −0.544, p = 0.003) caused significant reductions in hs-CRP. Besides, there was a significant reduction in hs-CRP with an intervention duration more than 24 weeks (SMD = −0.465, p = 0.001), while no significant difference with <24 weeks. Meta-regression analyses showed that better glycemic control and more body mass index (BMI) decline were associated with hs-CRP reduction after incretin-based therapies. Conclusions: This meta-analysis suggests that incretin-based therapies, both GLP-1 RAs and DPP-4Is, can cause a significant reduction in hs-CRP in patients with T2DM, which is related to long intervention duration, better glycemic control, and more BMI decline.

Blood pressure and its association with antiparkinsonian medications in patients with Parkinson′s disease / 中华神经科杂志

Parkinson′s disease (PD) is the second most common neurodegenerative disease following Alzheimer′s disease. The non-motor symptoms of PD have attracted increasing attention. The occurrence of abnormal blood pressure is related to many factors, including aging, PD related autonomic nerve dysfunction, and drugs for PD treatment,including levodopa, dopamine receptor agonists. Abnormal blood pressure severely limits the clinical use of anti-PD drugs. In order to better understand the relationship between anti-PD drugs and blood pressure in patients with PD. This article summarizes the manifestations of abnormal blood pressure, and analyzes the correlation between anti-PD drugs and blood pressure, summarizes the possible mechanisms of how anti-PD drugs affects the blood pressure in PD.

Beta-2 agonistas para el tratamiento de bronquiolitis / Beta-2 agonists for the treatment of bronchiolitis

INTRODUCCIÓN La bronquiolitis es la inflamación aguda de las vías aéreas de pequeño calibre, teniendo como causa principal las infecciones virales. Es altamente frecuente en menores de dos años, sobretodo en menores de 12 meses. Existe gran controversia sobre el manejo de esta patología, siendo especialmente cuestionable el uso de beta-2 agonistas de corta acción tanto en el ámbito ambulatorio como hospitalario. MÉTODOS Para responder esta pregunta utilizamos Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud a nivel mundial, la cual es mantenida mediante búsquedas en múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, reanalizamos los datos de los estudios primarios, realizamos un metanálisis, y preparamos una tabla de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES Identificamos siete revisiones sistemáticas que en conjunto incluyen 47 estudios primarios, de los cuales 44 corresponden a ensayos aleatorizados. Concluimos que el uso de beta-2 agonistas podría no tener ningún beneficio en el manejo de la bronquiolitis, en términos de necesidad de hospitalización y/o duración de la misma. Por otra parte, podría aumentar efectos adversos como arritmias, sin embargo, la certeza de esta evidencia es baja
