Medication Adherence Evaluated Through Electronic Monitors During the 2020 COVID-19 Pandemic Lockdown in Switzerland: A Longitudinal Analysis.

Background: During the 2020 COVID-19 lockdown, patients included in the Interprofessional Medication Adherence Program (IMAP) in Switzerland continued to use electronic monitors (EMs) that registered daily drug-dose intake. We aimed to understand to what extent patients' medication implementation (ie, the extent to which the patient took the prescribed medicine), measured with EMs, was impacted by the lockdown. Methods: Patients participating in the IMAP were diagnosed with diabetic kidney disease (DKD), solid cancer, human immunodeficiency virus (HIV) and miscellaneous long-term diseases (MLTD). Patient implementation was defined through a proxy: if all patient EMs were opened at least once daily, implementation was considered active (=1), and no implementation was considered (=0) otherwise. Implementation before (from December 2019 to March 2020), during (March to June 2020) and after (June to September 2020) the lockdown was compared. Subanalyses were performed according to the patients' diseases. Subanalyses were performed in patients who used at least one EM in 2018-2019 during the same periods (defined as winter, spring and summer). The logistic regression models used to estimate medication implementation according to the period were fitted using generalized estimating equations. Results: In 2020, patient implementation (n = 118) did not differ significantly before versus during (OR = 0.98, 95% CI: 0.84-1.15, p = 0.789) and before versus after (OR = 0.91, 95% CI: 0.79-1.06, p = 0.217) the lockdown. These findings remained stable when separately analyzing the implementation of patients with HIV (n = 61), DKD (n = 25) or MLTD (n = 22). Too few patients with cancer were included (n = 10) to interpret the results. In 2019, the implementation of 61/118 (51.7%) patients was significantly lower during summertime versus wintertime (OR = 0.73, 95% CI: 0.60-0.89, p = 0.002). Conclusion: Medication implementation remained steady before, during and after the lockdown in 2020. The IMAP before, during and after the lockdown may have supported the adherence of most patients, by ensuring continuity of care during periods of routine disturbances.

CME/Answers: Hypertension and the COVID-19 Pandemic: What to Consider in Medical Practice Abstract. The COVID-19 pandemic represents a major public health problem. A fraction of the population is at increased risk of developing complications of this disease, in particular older subjects as well as diabetic, obese and hypertensive patients. With regard to patients with high blood pressure, the existence of an increased risk remains to be confirmed in large controlled trials. So far the findings regarding this question are reassuring, whether these patients are treated or not. There seems to be no reason to worry when using blockers of the renin-angiotensin system. The observations available to date suggest that COVID-19 vaccine can be administered safely to hypertensive patients. In conclusion, there is no reason to implement changes in the care of hypertensive patients due to the pandemic.

Résumé. La pandémie COVID-19 représente un problème de santé publique majeur. Une partie de la population est à risque accru de développer des complications de cette maladie, en particulier les personnes âgées ainsi que les malades diabétiques, les obèses et, possiblement, les malades hypertendus. Pour ces derniers, cela reste à être confirmé dans des études contrôlées de grande envergure. Les connaissances accumulées à ce jour sont rassurantes, que les malades soient traités ou non. Il n'y a pas de crainte à avoir en ce qui concerne la prise de médicaments antihypertenseurs, y compris les bloqueurs du système rénine-angiotensine. Les premières observations indiquent que le vaccin anti-COVID-19 peut être administré chez le malade hypertendu avec la meme efficacité que le normotendu. En conclusion il n'y a pas de raison de prendre en charge le malade hypertendu autrement qu'avant l'apparition de la pandémie.

[Renin-angiotensin-aldosterone blockers and Covic-19 infection : friends or enemies ?]

ACE2 is not only an enzyme that counters the effects of the renin-angiotensin-aldosterone system (RAAS) but is also the entry receptor for SARS-CoV-2, the virus of the Covid-19 pandemic. Some experimental data suggest that ACE inhibitors and ARBs increase ACE2 levels, thus raising concerns on their security in Covid-19 positive patients. However, some studies have shown protection by these drugs in lower tract respiratory infections and ARDS. The actual consensus is to continue the treatment with RAAS inhibitors, abrupt withdrawal, especially in patients with cardiac or renal conditions, being hazardous in terms of cardiovascular outcomes, except in patients hospitalized in intensive care with hemodynamic instability. This position statement is actually unanimous among all international learned societies.
