Dutch trends in the use of potentially harmful medication during pregnancy

Aims: Recent population-based data on drug utilization around pregnancy are lacking. This study aims to examine the prevalence of drug exposure in the Netherlands during the preconception, pregnancy and postpartum periods, with special emphasis on trends of potentially harmful medication over the years. Methods: A population-based study was conducted using records from the PHARMO Perinatal Research Network. From 1999 to 2017, the proportion of pregnancies during which women used any medication or potentially harmful medication was assessed, overall and stratified by timing of exposure relative to pregnancy and by the year of delivery. Results: Overall, 357 226 (73%) and 166 484 (34%) of 487 122 selected pregnancies were exposed to any and potentially harmful medication, respectively. Among these 487 122 pregnancies, preconception prevalence for use of potentially harmful medication was 43%, 24% during the first trimester, 19% during the second, 16% during the third, and 45% postpartum. A declining trend was observed for exposure to any medication, from 84% in 1999 to 68% in 2017. No clear changes were observed over time for the proportion of pregnancies exposed to potentially harmful medication. Conclusions: Our study shows that the use of potentially harmful medication was high over the last two decades. Although there was a declining trend over the years in overall medication use, during a steady one-third of pregnancies, women used potentially harmful medication. Our findings highlight the need for an increased sense of urgency among both healthcare providers and women of reproductive age regarding potential risks associated with pharmacological treatment during pregnancy

Prevalence of Drug Prescriptions and Potential Safety in Patients with Cirrhosis: A Retrospective Real-World Study

Introduction: Patients with cirrhosis are at risk for adverse drug reactions (ADRs) due to altered pharmacokinetics and pharmacodynamics. We aimed to determine the prevalence of drug prescriptions and the potential safety of these prescriptions in a real-world cohort of patients with cirrhosis. Methods: This was a retrospective cohort study based on linked real-world data from the Out-patient Pharmacy Database and the Hospitalisation Database of the PHARMO Database Network. Patients with a diagnosis of cirrhosis between January 1998 and December 2015 were included. Follow-up ended when the patient underwent a liver transplant, died, transferred out of the database, or on 31 December 2015. Prescription data were derived from a community pharmacy database and were compared with our previously developed safety recommendations for 209 drugs. Results: In total, 5618 patients were included and followed for a median of 3 years (interquartile range [IQR] 1–7). In the first year after the diagnosis, patients used a median of nine drugs (IQR 5–14), with proton pump inhibitors (prevalence 53.9%), aldosterone antagonists (43.6%), and sulfonamide diuretics (41.3%) being the most commonly used drug groups. Almost half (48.3%) of 102,927 prescript

COPD stands for complex obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) has extensively been reported as a complex disease affecting patients' health beyond the lungs with a variety of intra- and extrapulmonary components and considerable variability between individuals. This review discusses the assessment of this complexity and underlines the importance of transdisciplinary management programmes addressing the physical, emotional and social health of the individual patient.COPD management is challenging and requires advanced, sophisticated strategies meeting the patient's individual needs. Due to the heterogeneity and complexity of the disease leading to non-linear and consequently poorly predictable treatment responses, multidimensional patient profiling is crucial to identify the right COPD patient for the right treatment. Current methods are often restricted to general, well-known and commonly used assessments neglecting potentially relevant (interactions between) individual, unique "traits" to finally ensure personalised treatment. Dynamic, personalised and holistic approaches are needed to tackle this multifaceted disease and to ensure personalised medicine and value-based healthcare

Impact of the 2018 revised Pregnancy Prevention Programme by the European Medicines Agency on the use of oral retinoids in females of childbearing age in Denmark, Italy, Netherlands, and Spain: an interrupted time series analysis

Background: In March 2018, the European pregnancy prevention programme for oral retinoids was updated as part of risk minimisation measures (RMM), emphasising their contraindication in pregnant women. Objective: To measure the impact of the 2018 revision of the RMMs in Europe by assessing the utilisation patterns of isotretinoin, alitretinoin and acitretin, contraceptive measures, pregnancy testing, discontinuation, and pregnancy occurrence concomitantly with a retinoid prescription. Methods: An interrupted time series (ITS) analysis to compare level and trend changes after the risk minimisation measures implementation was conducted on a cohort of females of childbearing age (12-55 years of age) from January 2010 to December 2020, derived from six electronic health data sources in four countries: Denmark, Netherlands, Spain, and Italy. Monthly utilisation figures (incidence rates [IR], prevalence rates [PR] and proportions) of oral retinoids were calculated, as well as discontinuation rates, contraception coverage, pregnancy testing, and rates of exposed pregnancies to oral retinoids, before and after the 2018 RMMs. Results: From 10,714,182 females of child-bearing age, 88,992 used an oral retinoid at any point during the study period (mean age 18.9-22.2 years old). We found non-significant level and trend changes in incidence or prevalence of retinoid use in females of child-bearing age after the 2018 RMMs. The reason of discontinuation was unknown in >95% of cases. Contraception use showed a significant increase trend in Spain; for other databases this information was limited. Pregnancy testing was hardly recorded thus was not possible to model ITS analyses. After the 2018 RMM, rates of pregnancy occurrence during retinoid use, and start of a retinoid during a pregnancy varied from 0.0 to 0.4, and from 0.2 to 0.8, respectively. Conclusion: This study shows a limited impact of the 2018 RMMs on oral retinoids utilisation patterns among females of child-bearing age in four European countries. Pregnancies still occur during retinoid use, and oral retinoids are still prescribed to pregnant women. Contraception and pregnancy testing information was limited in most databases. Regulators, policymakers, prescribers, and researchers must rethink implementation strategies to avoid any pregnancy becoming temporarily related to retinoid use

Predictors of fatal and non-fatal cardiovascular events in ANCA-associated vasculitis: Data from the Toronto CanVasc cohort

Objectives: Patients with ANCA-associated vasculitis are at increased risk of cardiovascular events. The aim of the present study was to assess predictors of cardiovascular events in patients with granulomatosis with polyangiitis or eosinophilic granulomatosis with polyangiitis. Methods: This retrospective cohort study included patients from the Canadian Vasculitis Research Network cohort in Toronto. Characteristics at diagnosis were collected. During follow-up, non-fatal cardiovascular events were determined from the Vasculitis Damage Index; mortality and causes of death were recorded. Cox regression models were developed to determine predictors of cardiovascular events, defined as stroke or myocardial infarction. Results: A total of 336 patients were included (231 [69%] granulomatosis with polyangiitis; 105 [31%] eosinophilic granulomatosis with polyangiitis). The mean age at diagnosis was 44 (±18) years and 44% were male. The incidence rate for the combined outcome of all fatal and non-fatal events was 7.2 events per 1000 patient-years. In a multivariate model, family history of cardiovascular events and a higher Birmingham Vasculitis Activity Score at diagnosis were predictive of cardiovascular events (hazard ratio and 95% confidence interval 3.46 [1.06–11.28] and 1.09 [1.02–1.16] respectively). In a subgroup analysis there was no association between cardiovascular or disease-specific characteristics and cardiovascular events in eosinophilic granulomatosis with polyangiitis. Conclusions: In this cohort of patients with granulomatosis with polyangiitis and eosinophilic granulomatosis with polyangiitis, both traditional and disease-related risk factors were predictive of cardiovascular events. Further prospective studies should elucidate the impact of these and other modifiable risk factors on cardiovascular risk in ANCA-associated vasculitis

Relation between duration of the prodromal phase and renal damage in ANCA-associated vasculitis

Abstract Background In ANCA-associated vasculitis the acute phase of the disease is often preceded by prodromal symptoms. The aim of the present study was to analyze the relation between the duration of the prodromal phase and renal damage. Methods Patients with ANCA-associated vasculitis and renal involvement from a retrospective single-center cohort were divided into two equal groups based on the duration of the prodromal phase. The prodromal phase was defined as the time between first vasculitis related symptoms and the date of diagnosis. Clinical characteristics at diagnosis and renal items on the vasculitis damage index at 6 months were compared between the two groups. In addition, the relation between a long prodromal phase and 3-year end-stage renal disease and mortality as a composite outcome was studied. Results A total of 72 patients were included (age 64 ± 12 years; 74% male; 96% Caucasian). At diagnosis, in patients with a prodromal phase ≤22 weeks versus >22 weeks estimated glomerular filtration rate and proteinuria did not differ significantly (35 (interquartile range 50) versus 30 (50) ml/min p = 0.84; 75% versus 87%, p = 0.21 respectively). Furthermore, Birmingham Vasculitis Activity Scores were comparable (7 (3), p = 0.71). At 6 months, a long prodromal phase was associated with proteinuria (odds ratio 5.38, 95% confidence interval (CI) 1.47–19.62), but not with an estimated glomerular filtration rate ≤ 50 ml/min (odds ratio 0.89, 95% CI 0.33–2.37) in multivariable analyses. In addition, a long prodromal phase was associated with end-stage renal disease/mortality (hazard ratio 5.22, 95% CI 1.13–24.20). Conclusions A long prodromal phase was associated with proteinuria and 3-year end-stage renal disease/mortality, but not with a reduced renal function at 6 months. These results underline the importance of an early diagnosis in ANCA-associated vasculitis patients in order to improve renal outcomes

Cardiovascular events in anti-neutrophil cytoplasmic antibody-associated vasculitis: A meta-analysis of observational studies

Objectives. Several chronic inflammatory diseases are associated with cardiovascular disease, but the risk in ANCA-associated vasculitis is poorly quantified. The aim of the present study was to review the evidence for an increased cardiovascular risk, including ischaemic heart disease, cerebrovascular accidents and peripheral arterial disease, in patients with ANCA-associated vasculitis. Methods. A comprehensive systematic review was conducted in accordance with guidelines of preferred reporting items for systematic reviews and meta-analyses. The databases PubMed, Embase.com and the Cochrane Library (Wiley) were searched for original observational studies comparing vasculitis patients with at least one control group. Summary estimates were derived with a random-effects model and reported as relative risks. Results. One thousand three hundred and seventy-five studies were identified. Seven studies were included, comprising almost 14 000 ANCA-associated vasculitis patients vs general population controls in six studies and chronic kidney disease patients in one study. ANCA-associated vasculitis carried a relative risk of 1.65 (95% CI: 1.23, 2.22) for all cardiovascular events, 1.60 (95% CI: 1.39, 1.84) for ischaemic heart disease and 1.20 (95% CI: 0.98, 1.48) for cerebrovascular accidents. We did not find studies that addressed the risk for peripheral arterial disease separately. No heterogeneity was seen in the estimates. Conclusion. This meta-analysis of observational studies supports an increase in cardiovascular risk in patients with ANCA-associated vasculitis of ~65%, similar to that found in other chronic inflammatory diseases. Hence, there is a clear need for active cardiovascular risk management in patients with ANCAassociated vasculitis

Traditional and disease-related cardiovascular risk factors in ANCA-associated vasculitis: A prospective, two-centre cohort study

Objectives: ANCA-associated vasculitis (AAV) has been associated with increased risk of cardiovascular (CV) events. The aim was to assess traditional and disease-related CV risk determinants in a two-centre prospective cohort of AAV patients. Methods: Patients were recruited from centres in the Netherlands and Canada. A comprehensive CV risk assessment was performed at inclusion. Subjects were followed up yearly for 3–5 years until the first CV event, death or end of follow-up. Cox proportional hazards analyses were performed to relate baseline characteristics to the first CV event. Results: A total of 144 patients were included (mean age 62 years, female sex 44%, median Framingham risk score 14.3%). Insulin resistance was present in 73% of patients tested at inclusion, independent of concurrent prednisone therapy. After a median follow-up of 2.90 years, 16 patients (11%) experienced a CV event (14 non-fatal and 2 fatal). The incidence of CV events was 5.45 per 100 patient-years. Age, Framingham risk score, HbA1c level, Diabetes Mellitus (DM), and previous CV event were significantly associated with CV events. Other factors, such as sex, impaired renal function, dyslipidemia, hypertension, smoking history and microalbuminuria, or disease-specific variables, like ANCA serotype or disease activity, were not significantly related to CV events in univariable or age-adjusted cox regression analysis. Conclusions: Determinants of an increased CV risk were identified. Disease-related factors and treatments can further modify individual risk factors, such as for steroids causing chronic insulin resistance and DM. Treatment of risk factors is essential to optimize long-term outcomes in AAV patients
