The safety of drugs for inflammatory bowel disease during pregnancy and breastfeeding: the DUMBO registry study protocol of GETECCU.

BACKGROUND: Active disease during conception and pregnancy in women with inflammatory bowel disease (IBD) increases the risk of pregnancy complications and adverse neonatal outcomes. The use of IBD treatments during pregnancy should be weighed against their adverse effects on the neonate, but longer-term safety data and data on serious infection rates and malignancies postnatally are lacking, particularly for newer drugs, such as tofacitinib, vedolizumab and ustekinumab. METHODS: This ongoing, prospective registry study being conducted at 70 centres in Spain is enrolling pregnant women who are ⩾18 years, are at any point in pregnancy up to the end of the second trimester and have a diagnosis of Crohn's disease, ulcerative colitis or unclassified IBD. Patients will receive treatment decided independently by their IBD specialist. Each incident gestation will be followed up through pregnancy and the first 4 years postnatally. Three cohorts will be compared: biologicals exposed, immunomodulatory exposed and non-exposed. The primary endpoint is the risk of severe infection in newborns postnatally up to 4 years of age; other endpoints include serious adverse events (SAEs) such as pregnancy and delivery complications, neonatal SAEs, development [Ages and Stages Questionnaire-3 (ASQ3)], and malignancy incidence, up to 4 years of age. IBD specialists will collect maternal data (baseline/end of each trimester/1 month post-delivery), neonatal birth data, and the SAE and ASQ3 data in children exposed during pregnancy, reported every 3 months by the mother. Statistical analysis will include summary statistics for quantitative variables, comparisons of qualitative variables with significance set at p < 0.025 and a binary logistic regression model to determine the risk factors for severe infections. RESULTS: Enrolment began in September 2019 and study completion is expected in September 2028. CONCLUSIONS: This prospective, controlled study will provide evidence on the long-term safety profile in children after intrauterine and lactation exposure to biological and immunomodulatory IBD treatments, including data on postnatal severe infections, development and malignancies.

Ichthyosis follicularis, atrichia and photophobia (IFAP) and hereditary mucoepithelial dysplasia: Two syndromes that share a common clinical spectrum.

Ichthyosis follicularis, atrichia and photophobia syndrome (IFAP) is an X-linked inherited disease caused by pathogenic variants in the gene encoding the membrane-bound transcription factor peptidase, site 2 (MBTPS2). Clinical presentation includes ichthyosis follicularis, alopecia, photophobia and developmental delay. Hereditary mucoepithelial dysplasia (HMD) is a dominantly inherited disease characterized by keratitis, non-scarring alopecia, skin lesions including follicular keratosis, perineal erythema, and mucosal involvement. Recently, variants in SREBF1, a gene coding for a transcription factor related to cholesterol and fatty acid synthesis, have been associated with the disease. These two syndromes share a common clinical spectrum. Here, we describe an IFAP syndrome patient with a novel variant in the MBTPS2 gene and an HMD patient with a previously reported variant in the SREBF1 gene. In addition, we present a review of the literature describing the triad characterized by non-scarring alopecia, keratosis follicularis, and ocular symptoms common in both IFAP and HMD patients to raise awareness of these underdiagnosed diseases. We also highlight the subtle differences in clinical presentation between the two disorders to better enable differentiation.

Prescribers' compliance with summary of product characteristics of dabigatran, rivaroxaban and apixaban-A European comparative drug utilization study.

Despite a tremendous increase of direct oral anticoagulants (DOACs) prescriptions in recent years, only few data is available analysing prescribers' adherence to Summary of Product Characteristics (SmPC). We aimed to assess adherence to registered indications, contraindications, special warnings/precautions, and potential drug-drug interactions for three DOAC compounds (dabigatran, rivaroxaban, and apixaban) in six databases of five European countries (The Netherlands, United Kingdom, Spain, Denmark, and Germany). We included adult patients (≥18 years) initiating DOACs between 2008 and 2015. For several SmPC items, broad definitions were used due to ambiguous SmPC terms or lacking data in some databases. Within the study period, a DOAC was initiated in 407 576 patients (rivaroxaban: 240 985 (59.1%), dabigatran: 95 303 (23.4%), and apixaban: 71 288 (17.5%)). In 2015, non-valvular atrial fibrillation was the most common indication (>60% in most databases). For the whole study period, a substantial variation between the databases was found regarding the proportion of patients with at least one contraindication (inter-database range [IDR]: 8.2%-55.7%), with at least one special warning/precaution (IDR: 35.8%-75.2%) and with at least one potential drug-drug interaction (IDR: 22.4%-54.1%). In 2015, the most frequent contraindication was "malignant neoplasm" (IDR: 0.7%-21.3%) whereas the most frequent special warning/precaution was "prescribing to the elderly" (≥75 years; IDR: 25.0%-66.4%). The most common single compound class interaction was "concomitant use of non-steroidal anti-inflammatory drugs" (IDR: 3.0%-25.3%). Contraindications, special warnings/precautions, and potential drug-drug interactions were present in a relevant number of new DOAC users. Due to broad definitions used for some SmPC terms, overall proportions for contraindications are prone to overestimation. However, for unambiguous SmPC terms documented in the databases sufficiently, the respective estimates can be considered valid. Differences between databases might be related to "true" differences in prescription behaviour, but could also be partially due to differences in database characteristics.

A European multicentre drug utilisation study of the impact of regulatory measures on prescribing of codeine for pain in children.

PURPOSE: In June 2013, following recommendations from the World Health Organization (WHO) and Food and Drug Administration (FDA), the European Medicines Agency agreed updates to the codeine product information regarding use for pain in children younger than 12 years and children undergoing tonsillectomy or adenoidectomy (TA) for obstructive sleep apnoea. This study was conducted to (a) assess effectiveness of these measures on codeine prescribing in the "real-world" setting and (b) test feasibility of a study using a common protocol by regulators with access to databases. METHODS: The study was performed using BIFAP (Spain), CPRD (UK), and IMS® Disease Analyzer (France and Germany) databases. Prescribers included general practitioners (GPs) (France and UK), GPs and paediatricians together (Spain), and GPs, paediatricians, and ear, nose, and throat (ENT) specialists separately (Germany). Between January 2010 and June 2015, prevalence of codeine prescribing was obtained every 6 months, and a time series analysis (joinpoint) was performed. Codeine prescribing within ±30 days of TA was also identified. Furthermore, doses, durations, and prior prescribing of other analgesics were investigated. RESULTS: Over the 5-year period, codeine prescribing decreased in children younger than 12 years (by 84% in France and Spain, 44% in GP practices in Germany, and 33% in the United Kingdom). The temporal pattern was compatible with the regulatory intervention in France and the United Kingdom, whereas a decrease throughout the study period was seen in Germany and Spain. Decreased prescribing associated with TA was suggested in ENT practices in Germany. CONCLUSIONS: Codeine prescribing for children decreased in line with introduced regulatory measures. Multidatabase studies assessing impact of measures by EU regulators are feasible.

[Clinical-Epidemiological Profile of Patients Initiating Intensive Statin Therapy for the Secondary Prevention of Vascular Disease in Spain]. / Perfil clínico-epidemiológico de pacientes que inician terapia intensiva con estatinas para la prevención secundaria de enfermedad vascular en España.

BACKGROUND: The new recommendations regarding the utilization of high potency statins (intensive therapy) for the treatment of cardiovascular disease have been based on the extrapolation of data coming from clinical trials. The objective is to describe the clinical-epidemiological profile of statin therapy users for the secondary prevention of cardiovascular disease in Spain and to examine the predictors for intensive therapy initiation. METHODS: Cross-sectional study from a sample of 88,751 patients aged ≥45 years-old with previous cardiovascular disease which initiated statin therapy between 1st January 2007 to 31st December 2011. Dose treatments >40 mg simvastatin daily (or equivalent dose if different statin) were considered intensive therapy treatment. Multivariable logistic regression models were built for dependent summary variables to examine the association between and the intensive therapy utilization (vs low-moderate intensity therapy). RESULTS: 16,857 adult patients receiving a first prescription of statin for the secondary prevention of cardiovascular diseases were identified. Predictors for intensive therapy initiation were year of statin prescription, male gender (adjusted OR: 1.70; 95% CI: 1.44-2.00), age >75 years-old (1.39; 1.15-1.69), previous history of coronary artery disease (1.71; 1.44-2.04), previous history of transient ischemic attack (1.24; 0,97-1.59), smoking (1.62; 1.34-1.95), hypertension (1.41; 1.20-1.65) and recent use of fibrates (2.32; 1.27-4.26). CONCLUSIONS: The onset of intensive therapy with statins in secondary was determined by the type of vascular event and age (>75 years-old in which the risk benefit balance could be controversial). No statistically significant differences were found according to the LDL-c levels.

Risk of thromboembolism with thrombopoietin receptor agonists in adult patients with thrombocytopenia: Systematic review and meta-analysis of randomized controlled trials.

BACKGROUND AND OBJECTIVE: Romiplostim and eltrombopag are thrombopoietin receptor (TPOr) agonists that promote megakaryocyte differentiation, proliferation and platelet production. In 2012, a systematic review and meta-analysis reported a non-statistically significant increased risk of thromboembolic events for these drugs, but analyses were limited by lack of statistical power. Our objective was to update the 2012 meta-analysis examining whether TPOr agonists affect thromboembolism occurrence in adult thrombocytopenic patients. MATERIALS AND METHODS: We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs). Updated searches were conduced on PubMed, Cochrane Central, and publicly available registries (up to December 2014). RCTs using romiplostim or eltrombopag in at least one group were included. Relative risks (RR), absolute risk ratios (ARR) and number needed to harm (NNH) were estimated. Heterogeneity was analyzed using Cochran's Q test and I(2) statistic. RESULTS: Fifteen studies with 3026 adult thrombocytopenic patients were included. Estimated frequency of thromboembolism was 3.69% (95% CI: 2.95-4.61%) for TPOr agonists and 1.46% (95% CI: 0.89-2.40%) for controls. TPOr agonists were associated with a RR of thromboembolism of 1.81 (95% CI: 1.04-3.14) and an ARR of 2.10% (95% CI: 0.03-3.90%) meaning a NNH of 48. Overall, we did not find evidence of statistical heterogeneity (p=0.43; I(2)=1.60%). CONCLUSIONS: Our updated meta-analysis suggested that TPOr agonists are associated with a higher risk of thromboemboembolic events compared with controls, and supports the current recommendations included in the European product information on this respect.

Effectiveness of recommendations to prevent reactivation of latent tuberculosis infection in patients treated with tumor necrosis factor antagonists.

OBJECTIVE: To investigate the impact of official recommendations regarding the management of latent tuberculosis (TB) infection on the rate of active TB in patients receiving treatment with tumor necrosis factor (TNF) antagonists. METHODS: Data on active TB rates and on screening and treatment of latent TB infection were extracted from the BIOBADASER (Spanish Society of Rheumatology Database on Biologic Products), a registry of patients with rheumatic conditions treated with TNF antagonists. The rates of active TB among the BIOBADASER patients were compared with those in the background Spanish population, and BIOBADASER patients with rheumatoid arthritis (RA) were compared with a cohort of RA patients from the EMECAR (Morbidity and Clinical Expression of Rheumatoid Arthritis) study who were not treated with TNF antagonists and were followed up for 5 years. RESULTS: Active TB developed in 34 patients, of whom 32 started taking TNF antagonists prior to the official recommendations on latent TB infection (pre-OR) and 2 began treatment after the recommendations were issued (post-OR). All cases of TB occurred during treatment with infliximab, and 28 of these patients had RA. Pre-OR, the active TB rate in BIOBADASER patients was 20.9-fold higher than in the background Spanish population, while RA patients in the BIOBADASER had rates 22.6- and 6.2-fold higher than the background and EMECAR populations, respectively. Post-OR, 324 patients with a tuberculin skin test result > or =5 mm and/or chest radiograph findings suggestive of past TB were treated for 9 months with isoniazid (INH). Post-OR, active TB rates among the BIOBADASER patients decreased by 78% (incidence risk ratio [IRR] 0.22, 95% confidence interval [95% CI] 0.03-0.88; P = 0.008), while among RA patients in the BIOBADASER, the rate dropped by 83% and reached the EMECAR rate (IRR 1.0, 95% CI 0.02-8.2). There were no INH treatment-related hospitalizations or deaths. CONCLUSION: Strategies to treat latent TB infection that are tailored to the at-risk population can effectively and safely lessen the likelihood of active TB in patients treated with TNF antagonists.
