Abstract
AIM: Osteoporosis is a major risk factor for fractures. Poor persistence with osteoporosis medication hampers outcomes. This study assessed whether encouraging the formation of patient-led follow-up cooperatives between general practitioners (GPs) and community pharmacists improved medication persistence. METHODS All consecutive patients who attended an osteoporosis patient education program were invited to participate. They were given a logbook containing questionnaires they would bring to 6-monthly visits to their GP and pharmacist. The effect of this 3-year cooperative follow-up on persistence with medication and lifestyle changes was assessed. RESULTS In total, 121 patients (average age, 67 years; 93% female) participated. Poor cooperation between GPs and pharmacists was noted. Nevertheless, medication persistence ranged from 83% to 91% over the 6 visits. However, since patient drop-out rates were high and questionnaire return rates were low, a post-study medical chart review was performed. This confirmed that persistence was high (74%-83%) at 3 years post-enrollment, even for oral bisphosphonate-treated patients (73%-76%). However, adoption of anti-osteoporosis lifestyle changes was poor throughout the study: one- to two-thirds of the patients did not alter their diet, physical activity, or surroundings to prevent falls. CONCLUSION One study goal, namely, to encourage GPs and pharmacists to cooperate in patient follow-up, was not achieved. However, high medication persistence was observed. This may reflect the education program, patient empowerment, personalized attention from study personnel, and being in a study. Patient-centered approaches can thus significantly increase medication persistence in osteoporosis. Ongoing education may be needed to improve patient adoption of and persistence with lifestyle changes.

Abstract
INTRODUCTION hypertension (HTN) is the main risk factor for most morbidities of elderly subjects. The objective of this study was to identify the epidemiological and clinical characteristics of hypertension in octogenarians and to identify the factors associated with uncontrolled hypertension in this population. METHODS we used data collected in the outpatient cardiology department of the University Hospital of Sfax between 15th April 2019 and 15th May 2019 as part of the National Tunisian Registry of Hypertension. We included in our study patients aged 80 years or more with hypertension. We described the epidemiological and clinical profile of this population, and we studied the associations between uncontrolled hypertension and socio-demographic, lifestyle, clinical and therapeutic factors using logistic regression models. RESULTS we included 346 subjects (45.1% (n=156) male and 54.9% (n=190) female), with a mean age of 84.36 (SD 4.01) years. More than half of them had uncontrolled hypertension. Dyslipidemia was the most common cardiovascular risk factor found in 43.6 % (n=151) of patients followed by diabetes (35.5%, n=122). One-third of patients had a history of coronary artery disease and/or stroke. Renal failure and kalemia disorders were observed, respectively, in 12.1% (n=42) and 25.2% (n=40) of patients. In multivariate analysis, factors associated with uncontrolled hypertension (HTN) were male sex (adjusted odds ratio (aOR): 1.663, 95% confidence interval (CI): 1.045-2.647; p=0.032), diabetes (aOR: 1.66, 95%CI: 1.031-2.688; p=0.037,) and poor adherence to blood pressure (BP) medications (aOR: 1.960, 95%CI: 1.195-3.214; p=0.008). CONCLUSION our results showed that more than half of octogenarian hypertensive patients did not reach the BP target and that poor adherence to BP medications was the main factor of uncontrolled HTN. In this population, the presence of other comorbidities and poor adherence to BP medications are very common. Systematic research for behaviors suggesting poor medication adherence should be a priority for physicians caring for these patients.

Abstract
PURPOSE Familial hypercholesterolemia (FH) is a genetic disease characterized by increased levels of low-density lipoprotein cholesterol (LDL-C). It is underdiagnosed and undertreated despite relatively high prevalance and significant association with increased mortality. We aimed to determine treatment status and compliance in patients with LDL-C ≥ 250 mg/dL and FH. DESIGN Patients older than 18 years old and have a serum LDL-C ≥ 250 mg/dL between January 2010 to December 2016 were identified from the hospital database. A phone survey was performed. Demographic features, smoking status, alcohol use, exercise, cardiovascular disease (CVD), use of medication for dyslipidemia, and CVD and high cholesterol levels in the family were questioned. Dutch Lipid Clinical Network Criteria was used to classify patients. The study was registered to Clinicaltrials.gov in July 2020 (NCT04494464). RESULTS 1365 patients with a LDL-C ≥ 250 mg/dL were identified. Patients that could not be reached and who refused to interview were excluded and the data of 367 patients were analyzed. There were 248 (67.6%) female and 119 (32.4%) male patients and mean age was 50.52 ± 11.66. LDL-C was ≥330 mg/dL in 50 (13.6%) and 250-329 mg/dL in 317 (86.4%) patients. Forty (10.9%) patients were classified as definite, 181 (49.3%) as probable and 146 (39.8%) as possible FH. 213 (58.0%) patients were not receiving lipid-lowering treatment, and 162 (76.1%) stated that medication was never recommended previously, 30 (14.1%) had stopped medication him/herself and 21 (9.8%) had stopped medication with the advice of the physician. Among patients with definite/probable FH, 84 (38.0%) had CVD and the rate of lipid-lowering drug use in these patients was 58.3%. CONCLUSION A significant proportion of patients with LDL-C ≥ 250 mg/dL were not taking lipid-lowering drugs. Similar with many other studies, diagnosis, and treatment rates of FH patients were very low in our study. Further national studies are required to increase awareness of the disease in both physicians and patients.

Abstract
OBJECTIVE This study aimed to assess implementation adherence (how well the patient's actual intake matches the prescribed dosing regimen) to non-vitamin K antagonist oral anticoagulants (NOACs) and to explore experiences with and beliefs about NOACs in a real-world sample of long-term NOAC users. METHODS A cross-sectional observational study was conducted in home-dwelling adults who started taking a NOAC at least 1 year prior to inclusion. Pharmacy dispensing data were used to calculate the Medication Possession Ratio (MPR). Patients were recruited in 158 community pharmacies in Flanders, Belgium. They completed a questionnaire collecting basic characteristics and exploring self-reported adherence to NOACs (using the Medication Adherence Report Scale, MARS) and experiences with and beliefs about NOACs (using the Beliefs about Medicines Questionnaire, BMQ). RESULTS A total of 766 patients (mean age 76.2±8.8 years, median CHA2DS2-VASc score 4 (IQR=3-4)) were included. The majority (93.5%) used NOAC for stroke prevention in atrial fibrillation. The median MPR was 95.2% (IQR=87.8-99.7) which corresponds with half of the study population not taking their NOAC on at least 17 cumulative days per year. Almost 21% of participants reported non-adherence on the MARS (score <25), with unintentional non-adherence (forgetfulness) most frequently reported (15.4%). Although two-thirds of NOAC users indicated to experience adverse drug reactions, the BMQ demonstrated a positive attitude towards NOAC therapy, where necessity beliefs outweigh the concerns. CONCLUSIONS Our data indicate that long-term NOAC users have high implementation adherence and a positive attitude towards NOAC therapy. However, taking into account patients' thromboembolic risk and NOACs' short half-lives, further optimisation of NOAC use seems warranted in this population.

Abstract
BACKGROUND Sub-Saharan Africa is experiencing a rising burden of hypertension. Antihypertensive medications and diet are the cornerstone of effective hypertension control. AIMS To assess adherence to medication and salt restriction in 12 sub-Saharan countries, and to study the relationship between adherence and blood pressure control in patients with hypertension. METHODS We conducted a cross-sectional survey in urban clinics in twelve sub-Saharan countries. Data were collected on demographics, treatment and adequacy of blood pressure control in patients with hypertension attending the clinics. Adherence was assessed by questionnaires completed by the patients. Hypertension grades were defined according to European Society of Cardiology guidelines. Association between adherence and blood pressure control was investigated using multilevel logistic regression analysis, adjusting for age, sex and country. RESULTS Among the 2198 patients, 77.4% had uncontrolled blood pressure, 34.0% were poorly adherent to salt restriction, 64.4% were poorly adherent to medication and 24.6% were poorly adherent to both. Poor adherence to salt restriction (odds ratio [OR] 1.33, 95% confidence interval [CI] 1.03-1.72), medication (OR 1.56, 95% CI 1.25-1.93) or both (OR 1.91 1.39-2.66) was related to uncontrolled blood pressure. Moreover, poor adherence to both medication and salt restriction was related to a 1.52-fold (95% CI 1.04-2.22), 1.8-fold (95% CI 1.22-2.65) and 3.08-fold (95% CI 2.02-4.69) increased likelihood of hypertension grade 1, 2 and 3, respectively. CONCLUSIONS High levels of poor adherence to salt restriction and medication were noted in this urban sub-Saharan study; both were significantly associated with uncontrolled blood pressure, representing major opportunities for intervention to improve hypertension control in sub-Saharan Africa.

Abstract
OBJECTIVE To study whether the changes in bioequivalent drugs with different appearances are associated with an increase in lack of adherence and medication use errors, in patients >65years old treated with antihypertensive and lipid-lowering medications. DESIGN Observational longitudinal prospective cohort study with a one-year follow-up period between 1 January 2013 and 31 December 2014. LOCATION Primary Healthcare Centres in the Community of Madrid. PARTICIPANTS Patients ≥65years-old with a diagnosis of hypertension and/or dyslipidaemia receiving treatment with Enalapril and/or Amlodipine and/or Simvastatin. MAIN MEASUREMENTS Variables collected during a Primary Care consultation by means of a personal interview were: sociodemographic (age, gender, level of education), clinical variables, adherence (Morisky-Green test and direct counting), medication errors (number and type), medication changes and number, analytical (total cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides) and combined variable (error and/or adherence). There were 1 baseline and 4 quarterly visits. RESULTS The study included 274 patients with a mean age 72 (6.6) years, of whom 47.8% were female. Some medication changes were observed in 134 patients (48.9%), with a median of 3 (IQR 1-5) and a maximum of 11 changes. The risk of presenting with a medication use error or decreased adherence was increased in patients exposed to changes in all visits with RR 1.14 (1.16-1.69) at one year of follow-up. The most frequent error was the loss of dose. For each change in medication, the probability of a combined event increases by 41%. CONCLUSIONS The changes made in bioequivalent drugs with different appearance could increase the number of medication use errors and decrease the adherence. More studies should be carried out to assess how much this affects the control of the disease. The intervention section is not considered because it is an observational study.

Abstract
BACKGROUND Assessing adherence to growth hormone (GH) is challenging. The Easypod™ connect device delivers pre-set doses of recombinant human GH (r-hGH) and stores a digital record of adherence that can be shared with healthcare provider. We assessed adherence to r-hGH delivered with Easypod™ according to the approved pediatric indications for r-hGH: growth hormone deficiency (GHD), born small for gestational age (SGA) who failed to show catch-up growth and Turner syndrome (TS). METHODS ECOS (NCT01555528) was a multicenter (24 countries), 5-year, longitudinal, observational study, which aimed to evaluate country-specific adherence to r-hGH therapy prescribed via the Easypod™ electronic injection device. The primary endpoint was yearly adherence. Secondary endpoints were height velocity, height velocity standard deviation scores (SDS), height, height SDS and IGF-1 concentrations. Clinical and auxological data were obtained from medical records and adherence from Easypod™ logs. RESULTS This study included 147 Easypod™-naïve Mexican children assessed during 3 years (mean age: 9.96 ± 3.41 years, 56.8% boys, mean height SDS at baseline: - 2.17 ± 0.97): 118 with GHD, 24 SGA and 5 with TS. A total of 105 (71.4%) patients were GH naïve. Overall median adherence was > 90% over the first year of treatment and > 80% at 3 years. Adherence was not different by r-hGH indication or between GH-naïve or experienced patients. At 1-year follow-up, mean change in height SDS was 0.57 ± 0.34, whereas mean height velocity SDS was 2.85 ± 2.51. In all, 84.7% patients had normal IGF-1 concentrations at 1-year follow-up. Adherence was associated with change in height SDS (r = 0.239, p = 0.005) and height velocity SDS (r = 0.194, p = 0.027). CONCLUSION Adherence rates with the Easypod™ device are high and maintained over time in GHD, SGA and TS Easypod™-naïve Mexican patients. High adherence is associated with better outcomes. Easypod™ assists physicians in monitoring adherence to r-hGH.

Abstract
Combination therapies are often needed to modify the concomitant risk factors for cardiovascular disease. Nonadherence to cardiovascular medications is a relevant concern, especially in polytherapy. We conducted a population-based, cohort study with the aim of quantifying the level of adherence and its related determinants in patients exposed to free 3-drug combination therapies, namely concurrent use of angiotensin-converting-enzyme inhibitor (ACEi), calcium channel blocker (CCB), and statin or of ACEi, statin, and low-dose aspirin. Within Health Search Database, we selected a cohort of adult patients concurrently prescribed with ACEi, CCB, and statin, as well as those prescribed with ACEi, statin and low-dose aspirin, from the January 1, 2002 to the December 31, 2014. Adherent patients were concurrent users of triple free pill regimen with a proportion of days covered ≥80% during 1-year follow-up; demographics and clinical determinants of 1-year adherence were identified by multivariate logistic regression. We found that more than half of patients prescribed with triple free drug combination therapy with ACEi plus CCB plus statin or ACEi plus statin plus low-dose aspirin, were found to be nonadherent to these treatments. Males and patients at high/very-high cardiovascular risk were more likely to be adherent, whereas depression and atrial fibrillation were associated with nonadherence. Our findings indicate that sex, cardiovascular risk, presence of atrial fibrillation, and depression can influence adherence to polytherapy. In conclusion, given that patients suffering from multiple cardiovascular risk factors are at higher risk of fatal events, strategies are needed to improve medication adherence to combination therapies.

BMC neurology. 2019;(1):278
Abstract
BACKGROUND Wilson disease (WD) is genetically induced failure of copper metabolism which can be successfully treated with pharmacological agents. The prognosis for survival in most WD patients is favorable if diagnosis and anti-copper treatment are provided early. Many observations imply that persistence with drug treatment is generally low in patients with chronic diseases, which impact the treatment effectiveness, but such results are very limited in WD. The aim of our study was to assess persistence with treatment among WD patients, to analyze its effect on patient outcome and to identify factors that might be related to persistence. METHODS 170 newly diagnosed, symptomatic patients with WD who started treatment between 1995 and 2005 were analyzed retrospectively to assess treatment non-persistence, which was defined as at least one reported break of more than 3 months or minimum two breaks lasting longer than 2 months. Results were further analyzed according to selected clinical variables. RESULTS Only 74.1% of patients were persistent with treatment during the mean 11.7 years of follow up. Treatment persistence closely impacted positive clinical outcomes. In patients classified as persistent, improvement and lack of WD progression were observed more often compared to those classified as non-persistent (29.4 and 68.3% vs. 2.3 and 45.5%; p < 0.001, respectively). In contrast, non-persistent patients presented more often with worsening WD than persistent patients (52.3% vs. 2.4%). Type of WD treatment, gender, phenotypic presentation, adverse events and duration of treatment were not related to treatment persistence. Higher or upper/post-secondary education and a supportive family attitude towards treatment were the most important factors related to persistence. CONCLUSIONS One quarter of WD patients were not taking anti-copper treatment regularly and this had an important negative effect on clinical outcome. Family support played an important role in treatment persistence.

Abstract
INTRODUCTION The quality of chronic anticoagulation and predictor factors of poor anticoagulant control in patients under acenocoumarol were unknown in North Africa. METHODS It is an observational study, carried out between November 2015 and November 30, 2016. The international normalized ratio (INR) values were prospectively obtained, and TTR was calculated using the Rosendaal method. RESULTS Overall, 215 patients were included in this study, with a mean age of 63±0,8 years. The prevalence of poor anticoagulation control was 78.1%; 95% CI [72.2-83.2] (168 patients with TTR less than 65%). The median TTR with the Rosendaal method was 44.4%. After multivariate adjustment, variables significantly associated with adequate anticoagulation level were: history of ischemic stroke (Adjusted OR equal to 4.3, 95% CI: 1.4-12.9), associated prescription of antiplatelet therapy (Adjusted OR equal to 3.5, 95% CI: 1.1-11.2), daily prescribed dose of coumarins less than 6 mg (Adjusted OR equal to 6.4, 95% CI: 1.1- 36) and lower risk of bleeding assessed as HAS-BLED score (Adjusted OR: 0.5, 95% CI: 0.3-0.8). CONCLUSION The quality of anticoagulation management with VKA among outpatients who received acenocoumarol was suboptimal. Strategies should be undertaken by clinicians and patients to improve the quality of anticoagulation, to address challenges to adverse cardiovascular outcomes in individuals treated with chronic anticoagulation.
