Real-World Prescribing Patterns for Hypertensive Children in China from 2018 to 2021: A Cross-Sectional Multicenter Study.

Background: Pediatric hypertension become an early marker of cardiovascular diseases, but their antihypertensive drug use patterns are rarely known. Purpose: To investigate the epidemiological characteristics of pediatric hypertension and the use of antihypertensive drugs in the real world in China. Methods: In this study, the demographic, diagnosis, and medication prescription data including the antihypertensive drug types and comorbidities, were analyzed. The antihypertensive drugs use were evaluated according to the Chinese guidelines for hypertension. Results: 1301 prescriptions (number of visits) containing 1880 antihypertensive medical orders were collected. The average number of antihypertensive drugs per prescription was 1.45 (±0.75). The patients aged 16 to 18 (70.18%) accounted for the highest proportion. Kidney diseases (33.28%) were the most common comorbidities. Calcium channel blocker (CCB), angiotensin II receptor blocker (ARB), and ß receptor blocker (BB) were the most used antihypertensive drugs. The most frequent monotherapy was CCB, while that of two and three drugs combination were ARB+CCB and ARB+BB+CCB, respectively. Metoprolol (11.44%), nifedipine (10.64%), amlodipine (10.59%), valsartan (6.12%) were the most commonly used antihypertensive drugs. The utilization rate of fixed compound preparations was 7.34%. However, the percentage of recommended antihypertensive drugs was just 14.20%, while the recommended drug combination was 84.93% according to the guidelines. Conclusion: For the first time ever we reported the antihypertensive prescription analysis in children in a large area of China. Our data provided new insights into the epidemiological characteristics and drug use in hypertensive children. We found that the guidelines for medication management in hypertensive children were not routinely followed. The wide use of antihypertensive drugs in children and those with weak clinical evidence raised concerns regarding its rational use. The findings could lead to more effective management of hypertension in children.

Treatment strategies and pharmacist-led medication management for Helicobacter pylori infection.

Half of the world's population is Helicobacter pylori carrier. Updated guidelines and consensus have been issued across regions with the main aim of reducing social transmission and increasing H. pylori eradication rate. Although alternative therapies including traditional Chinese medicine and probiotics have also been used to improve H. pylori eradication rate in clinical practice, current mainstream treatment is still dependent on triple and quadruple therapies that includes antibacterial agents (e.g., amoxicillin and furazolidone) and proton pump inhibitor. Researches also assessed the eradication rate of optimized high-dose dual therapy in treating H. pylori infection. With the increase of antibiotic resistance rate, the treatment strategies for H. pylori infection are constantly adjusted and improved. Besides, low medication compliance is another key influencing factor for H. pylori treatment failure. Emerging studies indicate that pharmacists' intervention and new pharmaceutical care methods can enhance patient medication compliance, reduce adverse drug reactions, and improve H. pylori eradication rate. The purpose of this review is to summarize the advances in treating H. pylori infection and highlight the necessity of developing novel strategies to cope with the increasing challenges and to achieve personalized medication. Also, this review attaches great importance to pharmacists in optimizing H. pylori treatment outcomes as a routine part of therapy.

Chinese herbal injections for coronavirus disease 2019 (COVID-19): A narrative review.

BACKGROUND: The outbreak of Coronavirus disease 2019 (COVID-19) has caused more than 180 million infections and 3.9 million deaths. To date, emerging clinical evidence has shown the synergetic benefits of Chinese herbal injections in treating this contagious respiratory disease. This review aims to summarize and analyze the efficacy and safety of Chinese herbal injections in the therapy of COVID-19. METHODS: The literature from 3 electronic databases, PubMed, CNKI, and Web of Science, were searched using the search terms "COVID-19", "SARS-CoV-2", "traditional Chinese medicine", "herb", "herbal", and "injection". Then the identified articles were comprehensively evaluated. RESULTS: Limited data demonstrated that Chinese herbal injections could significantly improve the clinical outcomes of COVID-19 patients, especially in combination with conventional treatment strategies. The benefits of which were mainly associated with the relief of symptoms, prevention of secondary infection, regulation of inflammation and immune function. There was also evidence showing the inhibitory effects on SARS-CoV-2 replication in vitro. Nevertheless, available real-world data suggested the increased risk of adverse event. Furthermore, the defects of existing researches and the insights for discovering novel antiviral drugs were prospectively discussed. CONCLUSION: Evidence-based advances revealed that Chinese herbal injections such as XueBiJing injection and ShenMai injection, exerted potent effects against COVID-19. Further laboratory researches and clinical evaluation are needed to gather scientific evidence on the efficacy and safety.

Trends of complications in patients with Parkinson's disease in seven major cities of China from 2016 to 2019.

Parkinson's disease (PD) is a neurological disorder involving both motor and nonmotor symptoms. Multimorbidity acts synergistically to heighten the risk of adverse outcomes for patients with PD. Its complications have a major impact on the clinical management of PD. The present retrospective and multicenter study was first performed to describe the epidemiological characteristics of PD patients and assess the incidence of complications. The outpatient prescriptions for PD therapy were collected from hospitals in Beijing, Chengdu, Guangzhou, Hangzhou, Shanghai, Tianjin and Zhengzhou of China over a 40-day period per year, from the first half of 2016 to that of 2019. The survey covered the characteristics and representative complications of the study population. A total of 103 674 outpatient prescriptions for PD treatment from different graded hospitals of China were collected for final data analysis. It showed that 78.15% of PD patients were prescribed in the neurology department. 95.05% of the outpatient prescriptions were from general hospitals. We found that the overall PD prevalence was 0.47%, among which 52.96% of them were men. In addition, 82.10% of PD suffers were older than 60 years and 83.70% of them had complications. The top five highest frequencies of nonmotor complications in PD patients were sleep disorders, Alzheimer's disease, depression, lower urinary tract symptoms and constipation, with the proportions of 6.79, 3.87, 3.72, 3.32 and 2.40%, respectively. Meanwhile, the proportions of sleep disorders, Alzheimer's disease, and constipation were gradually increasing from 2016 to 2019. The characteristics of PD patients and the incidence of its complications were evaluated in the present prescription survey. These updated data provide evidence for further implementation of PD management.

Glycerol Infusion Versus Mannitol for Cerebral Edema: A Systematic Review and Meta-analysis.

PURPOSE: For the treatment of cerebral edema, the use of glycerol, an osmotic agent, as well as mannitol, is popular in Asia. However, the relative therapeutic benefit of glycerol remains unknown. The goal of this study was to investigate the comparative efficacy and safety of glycerol infusion versus mannitol infusion for cerebral edema. METHODS: A systematic search was performed in PubMed, Cochrane Central Register of Controlled Trials, Web of Science, EMBASE, and Scopus for all eligible articles published before July 2020, with no restrictions on language. Two reviewers independently screened the articles, extracted data, and carefully assessed the quality of the evidence. FINDINGS: Eight studies (6 clinical, 2 animal) were ultimately included in the qualitative analysis, and five were included in the quantitative analysis. Pooled analyses revealed nonsignificant differences in the successful control of cerebral edema (relative risk [RR], 0.97; 95% CI, 0.81-1.15). The combination therapy with glycerol led to a favorable trend in neurologic improvements. Regarding safety, glycerol was associated with a significantly lower risk of acute kidney injury (RR, 0.27; 95% CI, 0.11-0.69) and electrolyte disturbances (RR, 0.20; 95% CI, 0.06-0.64), as well as a lower possibility of rebound effects. No hemolysis was observed at the final follow-up. IMPLICATIONS: Although the data are limited, compared with mannitol, glycerol shows a similar level of effectiveness, a more favorable safety profile, and promising neurologic improvement in individuals with cerebral edema. Additional research is needed to confirm these findings. PROSPERO: CRD42020187702.

Chronic Obstructive Pulmonary Disease Treatment and Pharmacist-Led Medication Management.

Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death across the globe. Its repeated exacerbation will seriously worsen the quality of life, aggravate the patients' symptoms, and bring a heavy burden on the patients and the society. Understanding the current status of drug therapy and the role of pharmaceutical care is essential for the management of COPD. In addition to the drugs already on the market, recent clinical trials also show that emerging novel drugs for treating COPD are being developed to prevent the symptoms, reduce the frequency of acute exacerbation, and improve the quality of life. Recent progress in new drug research should lead to novel treatment options for COPD patients in future clinical practice. The pharmaceutical care has shown significantly favourable impacts on addressing drug-related problems, supporting its vital role in the management of COPD, especially when there are a wide range of therapeutic agents. This review not only provides an overview of current treatment strategies but also further underlines the importance of new drug development and pharmaceutical care for patients with COPD.

Comparative efficacy and safety of glycerol versus mannitol in patients with cerebral oedema and elevated intracranial pressure: A systematic review and meta-analysis.

WHAT IS KNOWN AND OBJECTIVE: Glycerol is thought to be superior to mannitol in the treatment of cerebral oedema and elevated intracranial pressure (ICP), particularly with safety concerns. However, the current evidence remains insufficient. Therefore, we aimed to compare the efficacy and safety of glycerol versus mannitol in this meta-analysis. METHODS: PubMed, EMBASE, Web of Science, CENTRAL, China National Knowledge Infrastructure, Wanfang Database, Chongqing VIP information, ClinicalTrials.gov, and the reference lists of relevant articles were searched for randomized controlled trials comparing glycerol and mannitol in patients with brain oedema and elevated ICP. Two investigators independently identified the articles, assessed the study quality and extracted data. Data analyses were performed using RevMan software. RESULTS AND DISCUSSION: Thirty trials involving 3144 patients met our inclusion criteria. Pooled data indicated that glycerol and mannitol had comparable effectiveness in controlling cerebral oedema (RR, 1.00; 95% CI, 0.97 to 1.03; p = .97), but the risks of acute kidney injury and electrolyte disturbances were significantly lower with glycerol (RR, 0.21; 95% CI, 0.16 to 0.27 and RR, 0.23; 95% CI, 0.17 to 0.30, respectively) than mannitol. Moreover, there seemed to be a lower probability of rebound ICP after the withdrawal of glycerol. Neither haemolysis nor elevated blood glucose levels were observed in the glycerol group. WHAT IS NEW AND CONCLUSION: Regarding the balance between efficacy and safety, glycerol could be an effective and more tolerable alternative therapy for cerebral oedema and elevated ICP than mannitol, especially for high-risk populations of renal failure.

Evaluation of different proton pump inhibitors combined with bismuth quadruple regimens in Helicobacter pylori eradication.

To evaluate the efficacy and economics of different proton pump inhibitors (PPIs) combined with bismuth quadruple regimens for Helicobacter pylori (Hp) eradication, a retrospective analysis method was used to collect Hp-positive patients who were treated with a bismuth-containing quadruple regimen (PPIs + amoxicillin + furazolidone + colloid pectin bismuth) from the outpatient department of gastroenterology in our hospital from January to June 2017. A total of 1410 patients were included in the study and divided into four groups according to different PPIs: group A (pantoprazole sodium enteric-coated capsules, 352 cases), group B (esomeprazole magnesium enteric-coated tablets, 462 cases), group C (pantoprazole sodium enteric-coated tablets, 392 cases) and group D (rabeprazole sodium enteric-coated tablets, 204 cases). The eradication rate of Hp and cost-saving in each group were then compared. There were no significant differences of gender (P = 0.526) and age (P = 0.366) between each Hp treatment regimen. The eradication rates of groups A, B, C and D were 91.48%, 89.83%, 86.73% and 90.69%, respectively. No statistical differences of Hp eradication rates were observed between each group yet (P > 0.05). However, the cost of group A was the lowest. In the present study, the Hp eradication rates between different PPIs regimens were similar in treating Hp infection. Nevertheless, the point in favor of pantoprazole capsules is the slightly higher Hp eradication rate and lower drug cost than other PPIs, which provides a significant evidence for the clinical medication decision in treating Hp infection.

Lianhua Qingwen prescription for Coronavirus disease 2019 (COVID-19) treatment: Advances and prospects.

BACKGROUND: An outbreak of Coronavirus Disease 2019 (COVID-19) which was infected by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), is still spreading and has led to unprecedented health emergency over the world. Though no specific drug has been developed so far, emerging agents have been confirmed effective or potentially beneficial to restrain it. Lianhua Qingwen (LHQW) is a commonly used Chinese medical preparation to treat viral influenza, including in the fight against SARS in 2002-2003 in China. Recent data also showed that LHQW played a vigorous role in COVID-19 treatment. PURPOSE: This review will elucidate the pre-clinical and clinical evidence of LHQW in lung protection and antiviral activities, and provide timely data delivery for the exploration of effective treatment strategies in the therapy of COVID-19. STUDY DESIGN AND METHOD: The research data were obtained from the academic databases (up to August 8, 2020) including Pubmed, CNKI and Web of Science, on ethnobotany and ethno medicines. The search keywords for screening the literature information were "virus", "COVID-19", or "SARS-CoV-2", and "Lianhua Qingwen". The documents were filtered and summarized for final evaluation. RESULTS: The collected evidence demonstrated that LHQW exhibited benefits against COVID-19. Impressively, LHQW in conjunction with conventional treatment could significantly improve COVID-19 patients as a synergetic strategy. The mechanisms were mainly involved the antiviral activity, and regulation of inflammation response as well as immune function. CONCLUSION: Although the data were far from adequate, the latest advances had shown the benefits of LHQW in COVID-19, especially in combination with other antiviral drugs. This review provides comprehensive evidence of LHQW as a complementary strategy for treating COVID-19. Nevertheless, imperious researches should be conducted to clarify the unconfirmed effects, regulatory mechanisms and adverse reactions of LHQW in treating COVID-19 by means of well designed randomized controlled trials.

The status of proton pump inhibitor use: a prescription survey of 45 hospitals in China

Background: proton pump inhibitors (PPI) have been widely used in the clinic but inappropriate prescribing has also increased dramatically. Objective: to describe the prescribing patterns and assess the appropriateness of the prescribed PPI use in 45 hospitals in China. Materials and methods: PPI prescriptions for non-hospitalized patients were collected from hospitals in Beijing, Chengdu, Guangzhou and Hangzhou of China over a 40-day period in 2016. These data were analyzed using the prescription number, proportion and economic indicators (defined daily dose system [DDD], defined daily cost [DDC] and drug utilization index [DUI]). The evaluation criteria of PPI use was based on Martindale: The Complete Drug Reference, New Materia Medica and drug instructions. Results: in total, 357,687 prescriptions using oral PPI and 38,216 prescriptions using injectable PPI were assessed. The average age of PPI users was 53 years. The most commonly used oral PPI was rabeprazole, while the most common injectable PPI was pantoprazole. The DDD of oral rabeprazole and DDC of injectable rabeprazole were the highest. Meanwhile, only the DUI values of oral rabeprazole, lansoprazole and ilaprazole were less than 1.0. The clinical diagnosis of some users included well identified risky comorbidities such as kidney disease (2.9%). Furthermore, between 32.6% and 56.8% of the PPI prescriptions were used for inappropriate indications. Conclusion: this survey demonstrated that PPI use was accompanied by unapproved indications and excessive dosages. Comprehensive measures are urgently needed to improve PPI use and reduce unnecessary drug costs

Astragaloside IV Improves Bleomycin-Induced Pulmonary Fibrosis in Rats by Attenuating Extracellular Matrix Deposition.

Pulmonary fibrosis is a devastating lung disorder with mysterious pathogenesis and limited treatment options. It is well-recognized that the uncontrolled proliferation of lung fibroblasts and differentiation of fibroblasts into myofibroblasts excessively produce extracellular matrix (ECM) proteins which contribute to the fibrosis change of the lungs. Thus, blocking ECM accumulation would delay fibrosis progression. In this study, we observed the effects of astragaloside IV (ASV) (10 mg/kg/d) on ECM proteins in bleomycin (BLM, 5 mg/kg)-treated rats. Our results showed that ASV not only ameliorated BLM-induced body weight loss, lung coefficient increase, histological changes and collagen secretion, but also reduced the levels of type III collagen (Col-III) in lung homogenate, laminin (LN) and hyaluronic acid (HA) in serum, as well as hydroxyproline (HYP) in lung tissue. Besides, ASV significantly down-regulated the levels of high-mobility group box1 (HMGB1) in serum and lung tissue, and inhibited the up-regulated expression of α-SMA (marker of myofibroblasts) in the lungs. Taken together, these findings indicate that ASV attenuates BLM-induced ECM deposition, supporting its use as a promising candidate to treat lung fibrosis.

Traditional Chinese medicine for pulmonary fibrosis therapy: Progress and future prospects.

ETHNOPHARMACOLOGICAL RELEVANCE: Pulmonary fibrosis (PF) is a chronic, debilitating and often lethal lung disorder. Despite the molecular mechanisms of PF are gradually clear with numerous researchers' efforts, few effective drugs have been developed to reverse human PF or even halt the chronic progression to respiratory failure. Traditional Chinese medicine (TCM), the main component of the medical practice used for more than 5000 years especially in China, often exerts wider action spectrum than previously attempted options in treating human diseases. Recent data have shown the anti-fibrotic benefits of the active ingredients from TCM in this field, which may represent an attractive source of the drug discovery against PF. AIM OF THE REVIEW: This review summarizes the pre-clinical and clinical evidence on the benefits of TCM and their active ingredients, and provides a comprehensive information and reliable basis for the exploration of new treatment strategies of botanical drugs in the therapy of PF. METHODS: The literature information was obtained from the scientific databases on ethnobotany and ethno medicines (up to Aug 2016), mainly from the Pubmed, Web of Science and CNKI databases, and was to identify the experimental studies on the anti-fibrotic role of the active agents from TCM and the involved mechanisms. The search keywords for such work included: "lung fibrosis" or "pulmonary fibrosis", and "traditional Chinese medicine", "extract" or "herb". RESULTS: A number of studies have shown that the active agents of single herbs and TCM formulas, particularly the flavonoids, glycosides and alkaloids, exhibit potential benefits against PF, the mechanisms of which appear to involve the regulation of inflammation, oxidant stress, and pro-fibrotic signaling pathways, etc. Besides, the processing methods for discovering TCM in treating PF were prospectively discussed. CONCLUSION: These research work have shown the therapeutic benefits of TCM in the treatment of PF. However, more continued researches should be undertaken to clarify the unconfirmed chemical composition and regulatory mechanisms, conduct standard clinical trials, and evaluate the possible side effects. The insights provided in present review will be needed for further exploration of botanical drugs in the development of PF therapy.

Ophiopogon japonicus strains from different cultivation regions exhibit markedly different properties on cytotoxicity, pregnane X receptor activation and cytochrome P450 3A4 induction.

Maidong, known as Ophiopogon japonicus, is one of the two basic ingredients of Shenmai injection, which is a widely used herbal preparation in traditional Chinese medicine (TCM) for the treatment of atherosclerotic coronary heart disease and viral myocarditis. Previously, the ethanol extract of Maidong activated the pregnane X receptor (PXR) signaling pathway and induced the cytochrome P450 3A4 (CYP3A4) reporter gene and raised the concern of herb-drug interactions (HDIs) when Maidong was used in combination with prescribed drugs metabolized by CYP3A4. Therefore, the present study further investigated and compared the differences of the ethanol and aqueous extracts (ee- and ae-, respectively) of two Maidong strains, known as Zhe Maidong (ZM) and Chuan Maidong (CM). Cytotoxicity, PXR activation and CYP3A4 induction by the 3-(4,5)-dimethylthiahiazo-(-z-y1)-3,5-diphenytetrazoliumromide assay, reporter gene assay and reverse transcription-quantitative polymerase chain reaction analysis were examined. The observations showed that ee-ZM demonstrated a significantly higher cytotoxicity, a relatively weaker PXR activation capability and a markedly stronger CYP3A4-inducing capacity than ee-CM. Compared to ae-CM, ae-ZM exhibited only a slight or no difference on cytotoxicity and CYP3A4 induction, while a significant lower level of PXR activation was apparent. Collectively, Maidong from different producing areas possess different properties upon cytotoxicity and the drug-metabolizing enzyme inducing effect, and attention should be paid to the selection of Maidong strains from different planting regions into TCM preparations for reducing potential adverse reactions and HDIs.
