Evaluation of adherence to pharmacological treatments by undocumented migrants with chronic diseases: a 10-year retrospective cohort study.

OBJECTIVES: To investigate the time course of medication adherence and some of the factors involved in this process in undocumented migrants with chronic diseases. DESIGN: Retrospective cohort study. SETTING: A big non-governmental organisation in Milano, Italy, giving medical assistance to undocumented migrants. PARTICIPANTS: 1918 patients, 998 females and 920 males, with at least one chronic condition (diabetes, cardiovascular diseases (CVDs), mental health disorders) seen over a period of 10 years (2011-2020). Their mean age was 49.2±13 years. RESULTS: Adherence to medications decreased over 1 year in all patients. This was more evident during the first 2 months of treatment. Patients on only one medication were less adherent than those on more than one medication; at 6 months the percentage of patients with high adherence was 33% vs 57% (p<0.0001) for diabetes, 15% vs 46% (p<0.0001) for mental disorders and 35% vs 59% (p<0.0001) for CVDs. Patients with mental disorders had the lowest adherence: 25% at 6 months and 3% at 1 year. Mental disorders, when present as comorbidities, greatly reduced the probability of being highly adherent: risk ratio (RR) 0.72 (95% CI 0.57 to 0.91; p=0.006) at 3 months, RR 0.77, (95% CI 0.59 to 1.01; p=0.06) at 6 months, RR 0.35 (95% CI 0.13 to 0.94; p=0.04) at 1 year. This was especially evident for patients with CVDs, whose percentage of high adherents decreased to 30% (p=0.0008) at 6 months and to 3% (p=0.01) at 1 year. We also noted that highly adherent patients usually were those most frequently seen by a doctor. CONCLUSIONS: Interventions to increase medication adherence of undocumented migrants with chronic diseases are necessary, particularly in the first 2 months after beginning treatment. These should be aimed at people-centred care and include more outpatient consultations. Educational interventions should especially be taken into consideration for patients on monotherapy.

Cost-utility analysis of add-on vericiguat for the treatment of chronic heart failure with reduced ejection fraction in China.

OBJECTIVE: This study aimed to evaluate the cost-utility of the addition of vericiguat for treating chronic heart failure (CHF) in China from the healthcare payer's perspective. METHODS: A Markov model was built to estimate the cost and utility of treating CHF using vericiguat plus standard treatment (vericiguat group) vs. standard treatment alone (standard treatment group). The clinical parameters (mortality of cardiovascular and hospitalization rate of HF) were calculated according to the VICTORIA clinical trial. The HF cost and utility data were obtained from the literature published in China. One-way sensitivity analysis and probability sensitivity analysis were performed. RESULTS: According to the 13-year model, vericiguat was more expensive (155599.07 CNY vs. 259396.83 CNY) and more effective (4.41 QALYs vs. 4.54 QALYs). The incremental cost-utility ratio (ICUR) was 802389.27 CNY per QALY. One-way sensitivity analysis revealed that cardiovascular mortality in the two groups was the parameter that had the greatest impact on the results. The GDP per capita in 2022 in China was 85,700 CNY. The probability sensitivity analysis (PSA) showed that the probability of vericiguat being cost-effective was only 41.7% at the willingness-to-pay (WTP) threshold of 3 times GDP per capita (257,100 CNY). CONCLUSIONS: In China, the treatment of CHF with vericiguat is not cost-effective. The drug price could decrease to 145.8 CNY, which could be considered cost-effective.

Dietary Influence on Drug Efficacy: A Comprehensive Review of Ketogenic Diet-Pharmacotherapy Interactions.

It is widely acknowledged that the ketogenic diet (KD) has positive physiological effects as well as therapeutic benefits, particularly in the treatment of chronic diseases. Maintaining nutritional ketosis is of utmost importance in the KD, as it provides numerous health advantages such as an enhanced lipid profile, heightened insulin sensitivity, decreased blood glucose levels, and the modulation of diverse neurotransmitters. Nevertheless, the integration of the KD with pharmacotherapeutic regimens necessitates careful consideration. Due to changes in their absorption, distribution, metabolism, or elimination, the KD can impact the pharmacokinetics of various medications, including anti-diabetic, anti-epileptic, and cardiovascular drugs. Furthermore, the KD, which is characterised by the intake of meals rich in fats, has the potential to impact the pharmacokinetics of specific medications with high lipophilicity, hence enhancing their absorption and bioavailability. However, the pharmacodynamic aspects of the KD, in conjunction with various pharmaceutical interventions, can provide either advantageous or detrimental synergistic outcomes. Therefore, it is important to consider the pharmacokinetic and pharmacodynamic interactions that may arise between the KD and various drugs. This assessment is essential not only for ensuring patients' compliance with treatment but also for optimising the overall therapeutic outcome, particularly by mitigating adverse reactions. This highlights the significance and necessity of tailoring pharmacological and dietetic therapies in order to enhance the effectiveness and safety of this comprehensive approach to managing chronic diseases.

Integration of persistence in the 5P-medicine approach for age-related chronic diseases.

5P medicine is defined as Personalized, Predictive, Preventive, Participatory, and Population-based. 5P medicine may be improved by including a factor that could provide information about the therapeutic value of a particular drug treatment and measure its effectiveness in clinical practice. We propose that this factor may be treatment persistence, and that its addition to 5P medicine would allow to define a new improved 6P medicine. Persistence is the length of time between initiation and the last dose, which immediately precedes discontinuation, that is, a definitive suspension of the treatment. By including this sixth P, the persistence, we would be able to present the value of a treatment for each individual patient with its own characteristics, state of the disease, with more than one age-related diseases and patient journey. Persistence is a concept of the value of a treatment that includes the three main stakeholders of the pharmacotherapeutic process: Patient, Physician, and Pharmacist. Persistence is becoming a useful measure to evaluate the long-term effectiveness of therapies in real-world setting in chronic diseases. Drug treatments with longer persistence are more likely to provide better disease control and to be amenable to dose adjustment in order to optimize treatment cost in age-related chronic diseases. Long-term persistence could be a measure of a drug´s real-world performance and has been shown to aid in clinical decision-making.

Effect of pregabalin initiation on diuretic requirements in patients with chronic heart failure.

BACKGROUND: Literature on pregabalin use in patients with heart failure is largely limited to patient case reports and cohort studies. OBJECTIVE: This study aimed to evaluate the effect of pregabalin initiation on diuretic requirements in patients with heart failure. METHODS: A retrospective analysis of patients with heart failure who were started on pregabalin between January 1, 2014, and September 1, 2021, at the Veterans Affairs North Texas Health Care System was used. The primary objective was to determine the median change in loop diuretic dose, in furosemide dose equivalents, 6 months after pregabalin initiation. RESULTS: Of 58 patients analyzed, there was no statistically significant difference in the primary outcome (P = 0.162). The secondary outcomes were found to be nonstatistically significant, and there was no correlation between pregabalin dose and outcomes. CONCLUSION: This represents the largest analysis of diuretic dose requirements in patients with heart failure after initiation of pregabalin. Although there was no difference in the median change of diuretic dose prescribed, pregabalin should still be used with caution.

Patient activation and medication adherence in adults.

BACKGROUND: Patients' level of medication adherence provides conflicting results in its relationship to patient activation. Multiple factors may be contributing to these mixed results. OBJECTIVES: The primary purpose was to assess the association of patient activation to medication adherence in adults with chronic health conditions and low health literacy (HL). Secondary objectives were to determine whether age, education, gender, and race were associated with activation. METHODS: Participants completed self-report questionnaires regarding chronic disease self-management. Patient activation was measured using Hibbard's Patient Activation Measure (PAM). Self-report of medication adherence was determined using the Gonzalez-Lu adherence questionnaire. Block regressions first assessed the relation of demographic variables and education to adherence and then the added relation of patient activation in a second model. RESULTS: The analyses included 301 participants (mean age 58 years; 53% female; mean chronic conditions of 6.6). Some of the most common chronic conditions included hypertension (60%), arthritis (51%), depression (49%), and hyperlipidemia (43%). The relation of older age to greater medication adherence was significant (P < 0.05) in both models. The addition of PAM was significantly related to better adherence (P < 0.001) and also increased the R squared value from 0.04 to 0.09. This change resulted in a moderate effect size (d = 0.50). CONCLUSION: Evaluating patient activation at baseline may predict those more likely to be medication adherent in patients with low HL.

Pertinence de l'exigence d'un essai préalable avec un immunosuppresseur dans les indications de paiement des médicaments biologiques: gastroentérologie et dermatologie / Relevance of the prerequisite of the use of an immunosuppressant drug for the coverage of biologic agents (gastroenterology and dermatology)

INTRODUCTION: Au cours des dernières années, les médicaments biologiques se sont ajoutés à l'arsenal thérapeutique des maladies inflammatoires chroniques. Afin d'assurer un usage responsable de ces agents coûteux, leur paiement est actuellement autorisé suivant l'essai préalable de certains traitements conventionnels, notamment des immunosuppresseurs, à moins d'intolérances ou de contre-indications. Toutefois, des associations médicales en gastroentérologie et en dermatologie font état d'un décalage entre les indications de paiement des médicaments biologiques et les meilleures pratiques cliniques. Actuellement, lorsque l'utilisation des médicaments biologiques sans l'essai préalable des immunosuppresseurs est requise, une assistance par un programme de soutien aux patients et aux patientes pourrait être offerte par les fabricants des médicaments biologiques, selon certaines conditions. Dans le traitement des maladies inflammatoires de l'intestin, l'utilisation précoce des médicaments biologiques par le biais de ces programmes de soutien semble être une pratique bien établie et largement répandue depuis plusieurs années. Avec l'entrée en vigueur en avril 2021 de l'article 80.2 de la Loi sur l'assurance médicaments, lequel interdit le paiement ou le remboursement d'un médicament ou d'une fourniture dont le paiement est couvert par le régime général d'assurance médicaments, des associations médicales ont partagé des préoccupations quant à l'accès des médicaments biologiques sans l'essai préalable des immunosuppresseurs au ministère de la Santé et des Services Sociaux (MSSS). Notons que les médicaments biologiques, qu'ils soient de référence ou biosimilaires, font actuellement partie des exceptions prévues au règlement. Afin d'évaluer la pertinence des préalables de traitement dans les indications de paiement des médicaments biologiques, le MSSS a demandé à l'Institut national d'excellence en santé et en services sociaux (INESSS) de mobiliser les savoirs quant à la place des immunosuppresseurs et des médicaments biologiques dans les domaines de la gastroentérologie et de la dermatologie. MÉTHODOLOGIE: Tout d'abord, les indications de paiement des médicaments biologiques inscrits sur les listes de médicaments du Québec (ou dont la décision du ministre est en attente) ont été comparées à celles des autres provinces canadiennes. Ensuite, une revue rapide de la littérature a été réalisée pour répertorier notamment les recommandations des guides de pratique clinique (GPC) concernant la place des médicaments biologiques et des immunosuppresseurs dans la prise en charge de la maladie de Crohn chez l'adulte et l'enfant, de la colite ulcéreuse chez l'adulte et du psoriasis en plaques chez l'adulte. Finalement, les savoirs expérientiels et contextuels ont été recueillis par l'intermédiaire d'une invitation à recevoir des commentaires sur le plan de travail de l'INESSS et d'une consultation d'experts comprenant des gastroentérologues et des dermatologues. RÉSULTATS: Les GPC retenus dans les travaux relatent le manque d'étude de bonne qualité évaluant le moment optimal pour l'introduction des médicaments biologiques dans le traitement. Néanmoins, selon les données disponibles et le degré de valorisation de plusieurs autres facteurs, y compris les risques de complications, la gravité de la maladie, la réponse aux traitements antérieurs et les coûts, les sociétés savantes ont émis des recommandations concernant diverses séquences de traitement avec les médicaments biologiques, autant avant que suivant un traitement par les immunosuppresseurs. Pour le traitement des maladies inflammatoires de l'intestin, la plupart des GPC sélectionnés présentent des recommandations au sujet de l'utilisation des médicaments biologiques suivant un traitement conventionnel, lequel inclut l'acide 5-aminosalicylique (5-ASA) et (ou) les corticostéroïdes et (ou) les immunosuppresseurs. Plusieurs GPC font toutefois également état d'un changement de paradigme vers l'utilisation des médicaments biologiques en première intention de traitement, particulièrement chez les personnes qui ont des facteurs de risque de mauvais pronostic, afin de prévenir les complications, l'hospitalisation et le recours à la chirurgie. Très peu d'essais ont comparé l'efficacité des médicaments biologiques par rapport à celle des immunosuppresseurs, et ceux répertoriés ne sont pas représentatifs de la pratique clinique actuelle avec les médicaments biologiques. Les immunosuppresseurs sont généralement recommandés pour le maintien de la rémission et pourraient constituer une option de traitement acceptable suivant l'atteinte d'une rémission par les corticostéroïdes, mais leur utilisation suscite des préoccupations liées à leur innocuité, notamment le risque de lymphome T hépatosplénique associé aux thiopurines, telles l'azathioprine et la mercaptopurine. Pour le traitement du psoriasis en plaques, les recommandations issues des GPC sélectionnés concernant la place des médicaments biologiques dans le traitement sont peu nombreuses. Néanmoins, tous les GPC retenus s'accordent pour recommander l'utilisation des médicaments biologiques suivant un traitement par les agents de rémission systémiques conventionnels, lesquels incluent les immunosuppresseurs (principalement la cyclosporine et le méthotrexate) et l'acitrétine. Un GPC suggère également l'introduction précoce des médicaments biologiques dans des situations particulières. L'efficacité différentielle entre les médicaments biologiques et les agents de rémission systémiques conventionnels relève principalement de comparaisons indirectes. Une méta-analyse en réseau réalisée par le groupe Cochrane rapporte que la plupart des médicaments biologiques serait plus efficace que les agents de rémission systémiques conventionnels pour atteindre une réduction d'au moins 90 % sur le Psoriasis Area and Severity Index (PASI90). Par ailleurs, des enjeux d'innocuité sont liés aux agents de rémission systémiques conventionnels : le traitement continu par la cyclosporine n'est pas recommandé en pratique au-delà d'un an en raison des risques de néphrotoxicité, l'acitrétine pouvant causer des effets muco-cutanés et le méthotrexate, entraîner une hépatotoxicité. PERSPECTIVE DES EXPERTS ET AUTRES PARTIES PRENANTES: Pour le traitement des maladies inflammatoires de l'intestin, malgré l'absence de données de bonne qualité entre les immunosuppresseurs et les médicaments biologiques, les experts consultés estiment, selon leur expérience clinique, que les médicaments biologiques présentent une efficacité supérieure et un profil d'innocuité favorable par rapport aux immunosuppresseurs. Dans ce contexte, ils considèrent que l'essai des immunosuppresseurs avant l'autorisation des médicaments biologiques expose les patients à des risques de toxicité, de progression de la maladie et de complications. Afin d'éviter ces risques aux personnes qui en font usage, les cliniciens rapportent que l'utilisation des médicaments biologiques sans l'essai préalable des immunosuppresseurs par l'intermédiaire des programmes de soutien aux patients financés par les fabricants est une pratique bien établie au Québec depuis plusieurs années. En dermatologie, les cliniciens rapportent que les préalables de traitement dans les indications de paiement des médicaments biologiques pour le traitement du psoriasis en plaques pourraient forcer le choix d'options thérapeutiques souvent inappropriées pour les patients. Ils mentionnent que seul le méthotrexate dispose d'une réelle place dans le traitement du psoriasis en plaques modéré à grave. Les cliniciens reconnaissent que les délais engendrés par l'essai préalable d'au moins deux agents de rémission systémiques conventionnels, tel que requis actuellement dans les indications de paiement des médicaments biologiques, n'influencent pas le pronostic vital des patients. Toutefois, ils jugent important d'adapter le traitement à la condition particulière des personnes qui en font usage afin de réduire les plaques de psoriasis tout en limitant la survenue d'effets indésirables. CONCLUSIONS: Le moment optimal pour l'introduction des médicaments biologiques par rapport aux immunosuppresseurs dans les domaines de la gastroentérologie et de la dermatologie n'a pas été évalué dans des études de bonne qualité. Ainsi, les présents travaux démontrent une inadéquation entre la pratique clinique actuelle en gastroentérologie et les données probantes de bonne qualité disponibles. À ce propos, l'expérience clinique acquise au cours des dernières années avec les médicaments biologiques dans le traitement des maladies inflammatoires de l'intestin a mené les gastroentérologues à préconiser leur utilisation sans l'essai préalable des immunosuppresseurs. Les cliniciens estiment que l'exigence d'un traitement antérieur par les immunosuppresseurs dans les indications de paiement des médicaments biologiques pour le traitement des maladies inflammatoires de l'intestin devrait être retirée, principalement puisque les immunosuppresseurs retarderaient la guérison et exposeraient les patients à des risques de toxicité et de complications non négligeables, selon eux. Bien que la situation soit quelque peu différente en dermatologie, les cliniciens consultés soutiennent également le retrait de cette exigence pour le psoriasis en plaques.

INTRODUCTION: Over the past few years, biologic agents have been included in the therapeutic arsenal for treating chronic inflammatory diseases. To ensure responsible use of these costly drugs, their payment is currently only authorized following the use of conventional treatments (notably immunosuppressants), except in the presence of intolerances or contraindications. However, medical associations in gastroenterology and dermatology report a disconnect between coverage information for biologic agents and best clinical practices. At present, when biologic agents must be used without any prior trials of immunosuppressants, patients can, under certain conditions, receive assistance from biologic drug manufacturers for access through a patient support program. In the treatment of inflammatory bowel diseases, the early use of biologic agents through such support programs appears to be an established and widespread practice for several years. With the coming into force of section 80.2 of the Act respecting prescription drug insurance in April 2021, which prohibits the payment or reimbursement of a medication or supply covered by the Public Prescription Drug Insurance Plan, medical associations shared their concerns regarding access to biologic agents without any prior trials of immunosuppressants with the Ministère de la Santé et des Services sociaux (department of health issues and social services) (MSSS). It bears noting that biologic agents, whether they are reference products or biosimilars, are included in the exceptions provided for under the regulation. To assess the relevance of the prerequisite of the use of an immunosuppressant for the coverage of biologic agents, the MSSS asked the Institut national d'excellence en santé et en services sociaux (INESSS) to draw on the existing knowledge regarding the role of immunosuppressants and biologic agents in gastroenterology and dermatology. METHODOLOGY: First, coverage information for biologic agents listed on Québec drug formulary (or for which the Minister's decision is pending) was compared with that in other Canadian provinces. Then, a rapid review of the literature was performed to identify CPG (Clinical practice guidelines) recommendations regarding the place of biologic agents and immunosuppressants in the treatment algorithm of Crohn's disease in adults and children, ulcerative colitis in adults and plaque psoriasis in adults. Lastly, experiencebased and contextual knowledge was gathered through an invitation to receive feedback on the INESSS' work plan and from a consultation panel including gastroenterologists and dermatologists. RESULTS: The CPGs selected report a lack of quality studies on the best timing for incorporating biologic agents into a treatment plan. However, according to available data and the importance of several other factors, including the risk of complications, the severity of the illness, the response to previous treatments and the associated costs, learned societies made recommendations regarding various sequences of treatment with biologic agents, both before and after a treatment with immunosuppressants. For the treatment of inflammatory bowel diseases, most of the CPGs selected comprise recommendations as to the use of biologic agents following a conventional treatment that includes 5-ASA (aminosalicylic acids) and/or corticosteroids and/or immunosuppressants. Numerous CPGs, however, report a paradigm shift towards the use of biologic drugs as the front-line treatment, especially for persons at risk of a poor prognosis, to prevent complications, hospitalization and the need for surgery. Very few clinical trials have compared the efficacy of biologic agents and immunosuppressants, and the ones reported are not representative of current clinical practices with biologic agents. Immunosuppressants are generally recommended to maintain complete remission and could prove an acceptable treatment option once remission is achieved with corticosteroids; however, concerns associated with their safety have been raised, notably regarding the risk of hepatosplenic T-cell lymphoma due to thiopurines, such as azathioprine and mercatopurine. There are few recommendations in the selected CPGs regarding the role of biologic drugs in the treatment of plaque psoriasis. However, all of the CPGs selected agree in recommending the use of biologic drugs following a treatment with conventional systemic agents, which include immunosuppressants (primarily cyclosporine and methotrexate) and acitretin. One CPG also suggests resorting to the early use of biologic agents in special situations. The differential efficacy of biologic drugs and conventional systemic agents was mainly established through indirect comparisons. A network meta-analysis performed by Cochrane reports that most biologic drugs would be more effective than conventional systemic agents at achieving a decrease of at least 90% on the Psoriasis Area and Severity Index (PASI90). In addition, conventional systemic agents have certain safety issues: ongoing treatment with cyclosporine is not recommended beyond one year given the risks of nephrotoxicity, acitretin can cause mucocutaneous effects and methotrexate can induce hepatotoxicity. OPINIONS OF EXPERTS AND OTHER STAKEHOLDERS: For the treatment of inflammatory bowel diseases, despite the lack of quality data on immunosuppressants and biologic agents, the experts consulted believe, based on their clinical experience, that biologic agents offer a superior efficacy and a more favourable safety profile compared to immunosuppressants. Given this, they also consider that requiring a trial with an immunosuppressant before allowing the use of a biologic agent exposes patients to risks, among them toxicity, disease progression and complications. To avoid such risks, clinicians report that the use of biologic agents without the prior use of immunosuppressants through manufacturer-funded patient support programs is a wellestablished practice in Québec since many years. Clinicians in the field of dermatology report that the inclusion of preliminary treatments for the coverage of biologic agents in plaque psoriasis could result in patients being inappropriately treated. They mention that among the systemic drugs listed as prerequisite (acitretin, cyclosporin and methotrexate), methotrexate is the preferred agent for treating moderate to severe plaque psoriasis. The clinicians acknowledge that the delays resulting from the trial of at least two traditional systemic agents, as currently required in the coverage information for biologic agents, is not life-threatening for patients. However, they do believe that the treatment should be tailored based on the specific condition of the persons who benefit from it, to reduce psoriatic plaques while limiting the occurrence of adverse effects. CONCLUSIONS: The optimal timing for the introduction of biologics agents versus immunosuppressants in the field of gastroenterology and dermatology has not been assessed in good quality studies. Current research illustrates a discrepancy between actual clinical practices in gastroenterology and the quality evidence-based data available. The clinical experience using biologic drugs to treat inflammatory bowel diseases acquired over the past few years has led gastroenterologists to favour their use without a preliminary treatment with immunosuppressants. Clinicians consider that requiring such a prior treatment with immunosuppressants in the payment indications of biologic drugs for inflammatory bowel diseases should be ceased, mainly because immunosuppressants delay healing and expose patients to risks that include toxicity and non-negligeable complications. And while the circumstances are somewhat different in the field of dermatology, the clinicians consulted also support the removal of this requirement from payment indications of biologic drugs in the case of plaque psoriasis. Given a lack of data, this work did not evaluate the economic impact of withdrawing the requirement regarding prior treatment with immunosuppressants from the coverage information for biologic agents. This would likely generate a significant increase in costs, but the amounts involved should be compared to the cost of complications and other avoidable consequences. It should also be noted that a large portion of these costs are currently borne by the manufacturers, through patient support programs.

Recent Advances of Microneedles and Their Application in Disease Treatment.

For decades, scientists have been doing a lot of research and exploration to find effective long-term analgesic and/or disease-modifying treatments. Microneedles (MNs) are a simple, effective, and painless transdermal drug delivery technology that has emerged in recent years, and exhibits great promise for realizing intelligent drug delivery. With the development of materials science and fabrication technology, the MN transdermal drug delivery technology has been applied and popularized in more and more fields, including chronic illnesses such as arthritis or diabetes, cancer, dermatocosmetology, family planning, and epidemic disease prevention, and has made fruitful achievements. This paper mainly reviews the latest research status of MNs and their fabrication methodology, and summarizes the application of MNs in the treatment of various diseases, as well as the potential to use nanotechnology to develop more intelligent MNs-based drug delivery systems.

Efficacy and safety of gefapixant, a P2X3 receptor antagonist, in refractory chronic cough and unexplained chronic cough (COUGH-1 and COUGH-2): results from two double-blind, randomised, parallel-group, placebo-controlled, phase 3 trials.

BACKGROUND: Gefapixant is an oral P2X3 receptor antagonist that has previously shown efficacy and safety in refractory chronic cough and unexplained chronic cough. We therefore aim to confirm the efficacy and safety of gefapixant in participants with refractory chronic cough and unexplained chronic cough. METHODS: COUGH-1 and COUGH-2 were both double-blind, randomised, parallel-group, placebo-controlled, phase 3 trials. COUGH-1 was done in 156 sites in 17 countries and COUGH-2 in 175 sites in 20 countries. We enrolled participants who were 18 years or older with a diagnosis of refractory chronic cough or unexplained chronic cough of 1 year duration or more. Participants were also required to have a cough severity visual analogue scale score of 40 mm or more at screening and baseline. Eligible participants were randomly allocated (1:1:1), using a computer-generated allocation schedule, to one of three treatment groups: placebo, gefapixant 15 mg twice per day, or gefapixant 45 mg twice per day. All study treatments were given orally. Participants were treated over a 12-week main study period in COUGH-1 and a 24-week main study period in COUGH-2; followed by extension periods for a total of up to 52 weeks of treatment in both trials. The primary outcome was placebo-adjusted mean change in 24-h cough frequency at 12 weeks in COUGH-1 and 24 weeks in COUGH-2. Both studies were registered with ClinicalTrials.gov, NCT03449134 (COUGH-1) and NCT03449147 (COUGH-2). FINDINGS: From March 14, 2018, (first participant screened) to July 26, 2019, (last participant screened) 732 patients were recruited in COUGH-1 and 1317 in COUGH-2. COUGH-1 randomly assigned and treated 730 participants (243 [33×3%] with placebo, 244 [33×4%] with gefapixant 15 mg twice per day, and 243 [33×3%] with gefapixant 45 mg twice per day); COUGH-2 randomly assigned and treated 1314 participants (435 [33×1%] with placebo, 440 [33×5%] with gefapixant 15 mg twice per day, and 439 [33×4%] with gefapixant 45 mg twice per day). Participants were mostly female (542 [74×2%] of 730 in COUGH-1 and 984 [74×9%] of 1314 in COUGH-2). The mean age was 59×0 years (SD 12×6) in COUGH-1 and 58×1 years (12×1) in COUGH-2, and the mean cough duration was 11·6 years (SD 9·5) in COUGH-1 and 11·2 years (9·8) in COUGH-2. Gefapixant 45 mg twice per day showed significant reductions in 24-h cough frequency compared with placebo at week 12 in COUGH-1 (18·5% [95% CI 32·9-0·9]; p=0·041) and at week 24 in COUGH-2 (14·6% [26·1-1·4]; p=0·031). Gefapixant 15 mg twice per day did not show a significant reduction in cough frequency versus placebo in both studies. The most common adverse events were related to taste disturbance: ageusia (36 [4·9%] of 730 in COUGH-1 and 86 [6·5%] of 1314 in COUGH-2), dysgeusia (118 [16·2%] in COUGH-1 and 277 [21·1%] in COUGH-2), hypergeusia (3 [0·4%] in COUGH-1 and 6 [0×5%] in COUGH-2), hypogeusia (19 [2·6%] in COUGH-1 and 80 [6·1%] in COUGH-2), and taste disorder (28 [3·8%] in COUGH-1 and 46 [3·5%] in COUGH-2). INTERPRETATION: Gefapixant 45 mg twice per day is the first treatment to show efficacy with an acceptable safety profile in phase 3 clinical trials for refractory chronic cough or unexplained chronic cough.

Biguanide Pharmaceutical Formulations and the Applications of Bile Acid-Based Nano Delivery in Chronic Medical Conditions.

Biguanides, particularly the widely prescribed drug metformin, have been marketed for many decades and have well-established absorption profiles. They are commonly administered via the oral route and, despite variation in oral uptake, remain commonly prescribed for diabetes mellitus, typically type 2. Studies over the last decade have focused on the design and development of advanced oral delivery dosage forms using bio nano technologies and novel drug carrier systems. Such studies have demonstrated significantly enhanced delivery and safety of biguanides using nanocapsules. Enhanced delivery and safety have widened the potential applications of biguanides not only in diabetes but also in other disorders. Hence, this review aimed to explore biguanides' pharmacokinetics, pharmacodynamics, and pharmaceutical applications in diabetes, as well as in other disorders.

Albendazole reduces hepatic inflammation and endoplasmic reticulum-stress in a mouse model of chronic Echinococcus multilocularis infection.

BACKGROUND: Echinococcus multilocularis causes alveolar echinococcosis (AE), a rising zoonotic disease in the northern hemisphere. Treatment of this fatal disease is limited to chemotherapy using benzimidazoles and surgical intervention, with frequent disease recurrence in cases without radical surgery. Elucidating the molecular mechanisms underlying E. multilocularis infections and host-parasite interactions ultimately aids developing novel therapeutic options. This study explored an involvement of unfolded protein response (UPR) and endoplasmic reticulum-stress (ERS) during E. multilocularis infection in mice. METHODS: E. multilocularis- and mock-infected C57BL/6 mice were subdivided into vehicle, albendazole (ABZ) and anti-programmed death ligand 1 (αPD-L1) treated groups. To mimic a chronic infection, treatments of mice started six weeks post i.p. infection and continued for another eight weeks. Liver tissue was then collected to examine inflammatory cytokines and the expression of UPR- and ERS-related genes. RESULTS: E. multilocularis infection led to an upregulation of UPR- and ERS-related proteins in the liver, including ATF6, CHOP, GRP78, ERp72, H6PD and calreticulin, whilst PERK and its target eIF2α were not affected, and IRE1α and ATF4 were downregulated. ABZ treatment in E. multilocularis infected mice reversed, or at least tended to reverse, these protein expression changes to levels seen in mock-infected mice. Furthermore, ABZ treatment reversed the elevated levels of interleukin (IL)-1ß, IL-6, tumor necrosis factor (TNF)-α and interferon (IFN)-γ in the liver of infected mice. Similar to ABZ, αPD-L1 immune-treatment tended to reverse the increased CHOP and decreased ATF4 and IRE1α expression levels. CONCLUSIONS AND SIGNIFICANCE: AE caused chronic inflammation, UPR activation and ERS in mice. The E. multilocularis-induced inflammation and consecutive ERS was ameliorated by ABZ and αPD-L1 treatment, indicating their effectiveness to inhibit parasite proliferation and downregulate its activity status. Neither ABZ nor αPD-L1 themselves affected UPR in control mice. Further research is needed to elucidate the link between inflammation, UPR and ERS, and if these pathways offer potential for improved therapies of patients with AE.

Trend and effects of high-deductible health insurance plans in the health care system: financial access problems in management of cognitive impairment.

BACKGROUND: High-deductible health plans (HDHPs) are characterized by higher deductibles and lower monthly premiums compared with a typical health plan. HDHPs may reduce, or delay, needed care, which will ultimately lead to poorer access to care for chronically affected participants. OBJECTIVES: To (1) investigate the HDHP enrollment trend and (2) determine the effects of HDHPs on financial access problems for individuals with self-reported cognitive impairment. METHODS: Data between 2010 and 2018 were obtained from the National Health Interview Survey (NHIS). Individuals with cognitive impairment were identified if they were limited by memory difficulties. Problems regarding financial access to health care were assessed based on 6 survey questions from the Centers for Disease Control and Prevention. Multivariable logistic regressions were implemented to evaluate the effects of HDHPs. RESULTS: This study identified 1,148 individuals with cognitive impairment, representing 3.9 million individuals in the United States from 2010 to 2018. A nearly 2-fold increase in HDHP enrollment with cognitive impairment was observed from 2010 (20.9%) to 2018 (41.9%). This increase is similar to that reported for noncognitively impaired individuals. After controlling for possible confounding variables, cognitively impaired individuals with HDPHs were more likely to have overall financial access difficulties compared with those without HDHPs (OR = 1.17, 95% CI = 0.88-1.56, P = 0.271), but this likelihood was not statistically significant. CONCLUSIONS: HDHPs are intended to support effective care options and reduce health care costs. However, our research found that among individuals with cognitive impairment, those with HDHPs experienced some financial access problems, such as affording medical care, follow-up care, and specialists, than those without HDHPs, indicating that HDHPs might have unintended consequences for health care usage. DISCLOSURES: No outside funding supported this study. The authors have no conflicts of interest or financial interests to disclose.

The metabolic syndrome, thiazolidinediones, and implications for intersection of chronic and inflammatory disease.

BACKGROUND: Chronic disease appears connected to obesity. However, evidence suggests that chronic metabolic diseases are more specifically related to adipose dysfunction rather than to body weight itself. SCOPE OF REVIEW: Further study of the first generation "insulin sensitizer" pioglitazone and molecules based on its structure suggests that is possible to decouple body weight from the metabolic dysfunction that drives adverse outcomes. The growing understanding of the mechanism of action of these agents together with advances in the pathophysiology of chronic metabolic disease offers a new approach to treat chronic conditions, such as type 2 diabetes, fatty liver disease, and their common organ and vascular sequelae. MAJOR CONCLUSIONS: We hypothesize that treating adipocyte dysfunction with new insulin sensitizers might significantly impact the interface of infectious disease and chronic metabolic disease.

Profile of pharmaceutical interventions of a pharmacotherapeutic follow-up model for diabetic patients in a community pharmacy

Abstract The insertion of Pharmaceutical Care in Primary Health Care (PHC) improves patients' clinical outcomes and quality of life. Pharmacotherapeutic follow-up can contribute to the management of chronic diseases such as diabetes, promoting better glycemic control and adherence to therapy. This study aimed to assess the Drug-therapy Problems (DTPs) and Pharmacist Interventions (PIs) on the pharmacotherapeutic management in patients with type 2 diabetes mellitus (T2DM) in a community pharmacy. A quantitative, retrospective, and cross-sectional study was conducted in a Pharmaceutical Care Program within the PHC in Juiz de Fora (Minas Gerais, Brazil). Inclusion criteria were patients with T2DM above 18, who attended at least three pharmaceutical consultations between July 2016 and October 2018 and presented two or more glycated hemoglobin tests. The study group (n = 17) was largely composed of women (65%), elderly (76%), sedentary (72%), and obese people (52%). The resolution was achieved in 79% of the DTPs identified (n = 115). Most of DTPs were related to administration and adherence to pharmacotherapy (46%). 60% of the 437 PIs involved the provision of information and counseling. In other words, accessible interventions lead to high resolvability. Therefore, clinical actuation of pharmacists could improve the prognosis in diabetes treatment

Os desafios na adesão ao tratamento do paciente com hipertensão arterial / Challenges in treatment adherence among patients with arterial hypertension

As doenças cardiovasculares são a principal causa de morte e de incapacidade no mundo, com destaque para a hipertensão arterial sistêmica (HAS) como um dos principais fatores de risco. No manejo do paciente com HAS, um dos maiores desafios da prática clinica é a aderência ao tratamento. Tal fato se torna mais desafiador ainda em se tratando de doença crônica e na maioria das vezes assintomática. A falta de adesão ao tratamento ocasiona um mau controle da pressão arterial assim como também se associa a lesões de órgão-alvo, eventos cardiovasculares e morte. Fatores como complexidade do regime terapêutico, desconhecimento sobre a doença e suas complicações, sobrecarga da equipe assistencial e polifarmácia são barreiras importantes à aderência adequada. Entre as potenciais ferramentas a fim de mitigar este problema estão esquemas de medicamentos uma vez ao dia em comprimidos únicos, envolvimento da equipe multidisciplinar e uso de tecnologia digital.O entendimento amplo dos fatores que podem impactar a aderência pode melhorar o cuidado aos pacientes com HAS, com o objetivo de melhorar a qualidade de vida e sobrevida e reduzir a sobrecarga ao sistema de saúde (AU).

Cardiovascular diseases are the main cause of death and disability worldwide, being systemic hypertension among the main risk factors. In the management of patients with hypertension, one of the biggest challenges in clinical practice is treatment adherence. This fact is even more challenging considering the chronic and mostly assymptomatic nature of the disease. The lack of adherence to treatment not only results in poor control of blood pressure but also is associated with target-organ lesion, cardiovascular events and death. Factors such as therapeutic regimen complexity, lack of knowledge about disease complications, excess workload to heatlhcare professionals and polypharmacy are important barriers to adequate adherence. Among the potential tools that are available to mitigate this problem are single pill, once a day regimens; multidisciplinary approach; and digital technologies. The broad understanding of factors that may impact treatment adherence can improve care of patients with hypertension, with the goal of improving quality of life, prolonging survival and decreasing the burden to the health system

Tratamento da diarreia crônica com o medicamento homeopatico phosphorus: relato de caso / Treatment of chronic diarrhea with the homeopathic medicine phosphorus: case report

Há poucos estudos sobre a eficácia do tratamento homeopático na diarréia crônica, por isso relatos de casos são os primeiros degraus da evidência clínica [1]. As pesquisas utilizando medicamentos altamente diluídos têm avançado significativamente e a Medicina sempre está em busca de novas abordagens terapêuticas. Sendo a Homeopatia uma possibilidade no tratamento devido à sua alta resolutividade e baixo custo, comentamos sobre este tema que vem assumindo a cada dia mais importância na sociedade, devido aos impactos que provoca. Este relato de caso tem como objetivo principal apresentar o tratamento Unicista orientado por Hahnemann. Apresentamos o caso de uma paciente adulta que procurou consulta homeopática por diarréia crônica, após longo período de tratamento alopático sem resolução. Relatamos o atendimento, a repertorização e o tratamento com o medicamento policresto Phosphorus (simillimum da paciente). Demonstramos o surpreendente resultado obtido com o tratamento, respeitando a individualidade da paciente e observando os fundamentos da Homeopatia. Concluímos que a atuação do médico tem importância relevante na condução do tratamento e na melhora de qualidade de vida do seu paciente, e que a Homeopatia é uma grande aliada ao minimizar os danos deste transtorno. A cura de uma doença pode ser feita com tratamento homeopático Unicista segundo os ensinamentos do Pai da Homeopatia.

There are few studies on the effectiveness of homeopathic treatment in Chronic Diarrhea, so case reports are the first steps of clinical evidence. Researchs using highly diluted drugs has advanced significantly. Considering a challenge, Medicine is looking for new therapeutic approaches and Homeopathy is a possibility in the treatment due to its high resolution and low cost. We briefly comment on this topic, which is becoming increasingly important in society, due to the impacts it causes. This case report has as main objective to present the homeopathic treatment in a Unicist way according to the guidelines of Hahnemann. In the patient's search for homeopathy, we studied the case, performed the repertorization and found Phosphorus as the patient's simillimum. We demonstrate the surprising result obtained with the homeopathic treatment, respecting the patient's individuality and observing the fundamentals of Homeopathy. We conclude that the doctor's performance has relevant importance in the conduct of the treatment and in the improvement of the patient's quality of life, and that homeopathy is a great ally in minimizing the damage of this disorder. The cure of a disease can be done with Unicist homeopathic treatment according to the teachings of the Father of Homeopathy.

Resistance pattern of infected chronic wound isolates and factors associated with bacterial resistance to third generation cephalosporins at Mbarara Regional Referral Hospital, Uganda.

BACKGROUND: The objectives of this study were; (I) to determine the proportion of pathogens isolated from patients with infected chronic wounds in the surgical ward of MRRH that are resistant to the third-generation cephalosporins and (II) to determine the factors associated with resistance to third-generation cephalosporins in the surgical ward of MRRH. METHOD(S): This study was a descriptive analytical survey of bacterial isolates from infected chronic wounds among patients admitted in the surgical ward of MRRH, Uganda. Seventy five (75) study participants were recruited in the study using convenient sampling technique. Bacterial culture and identification was performed using standard microbiology laboratory procedures whereas broth microdilution method was used to establish the susceptibility of the identified pathogens. Data for objective one (1) was summarized as proportions while the categorized variables were analyzed using logistic regression to determine whether they were associated with the resistance patterns. The level of significance was preset at 5% and p-values less than 0.05 were considered statistically significant. RESULTS: Generally, all isolates had complete susceptibility (100%) to Cefoperazone+Sulbactam 2g except 7.1% of proteus spp that were resistant. Of all the bacterial isolates studied, Staphylococcus aureus, Enterobacter agglomerans, providencia spp and pseudomonas earuginosa had complete resistance (100%) to Cefopodoxime 200mg while providencia spp and pseudomomas earuginosa had complete resistance (100%) to Cefixime 400mg and cefotaxime 1g. Finally, higher odds of bacterial resistance to more 2 brands of the third generation cephalosporins were observed among participants who had prior exposure to the third generation cephalosporins (OR, 2.22, 95% CI, 0.80-6.14), comorbidities (OR, 1.76, 95% CI, 0.62-4.96) and those who had more than two hospitalizations in a year (OR, 1.39, 95% CI 0.46-4.25). However, multivariate logistic regression was not performed since no factor was significantly associated with resistance to more than two brands of third generation cephalosporins (p >0.05). CONCLUSION: This study found that cefixime and cefpodoixme had high rates of resistance and should not be used in routine management of infected chronic wounds. In addition, the factors investigated in this study were not significantly associated with bacterial resistance to more than two brands of third generation cephalosporins.
