RESUMEN
Pseudoxanthoma elasticum (PXE) is characterized by low levels of inorganic pyrophosphate (PPi) and a high activity of tissue-nonspecific alkaline phosphatase (TNAP). Lansoprazole is a partial inhibitor of TNAP. The aim was to investigate whether lansoprazole increases plasma PPi levels in subjects with PXE. We conducted a 2 × 2 randomized, double-blind, placebo-controlled crossover trial in patients with PXE. Patients were allocated 30 mg/day of lansoprazole or a placebo in two sequences of 8 weeks. The primary outcome was the differences in plasma PPi levels between the placebo and lansoprazole phases. 29 patients were included in the study. There were eight drop-outs due to the pandemic lockdown after the first visit and one due to gastric intolerance, so twenty patients completed the trial. A generalized linear mixed model was used to evaluate the effect of lansoprazole. Overall, lansoprazole increased plasma PPi levels from 0.34 ± 0.10 µM to 0.41 ± 0.16 µM (p = 0.0302), with no statistically significant changes in TNAP activity. There were no important adverse events. 30 mg/day of lansoprazole was able to significantly increase plasma PPi in patients with PXE; despite this, the study should be replicated with a large number of participants in a multicenter trial, with a clinical end point as the primary outcome.

BACKGROUND: Teleconsultation in the context of clinical laboratories is a valuable tool for the early detection of dyslipidemia and prevention of cardiovascular risk. Here, we describe a patient who was referred to the Lipid Unit of the Virgen Macarena Hospital due to an alert for severe hypertriglyceridemia through its teleconsultation program. CASE PRESENTATION: A comprehensive clinical and biochemical study of the patient was carried out, and genetic testing was performed on the patient and his family. The proband and his family showed mild to severe hypertriglyceridemia and various secondary factors, together with a genetic background associated with a triglyceride-raising effect. CONCLUSION: This extensive study has identified a family at high risk of cardiovascular disease and acute pancreatitis. These findings can help maximize lifestyle changes and improve the clinical management of their dyslipidemia.

AIMS: Limited data exist on low-density lipoprotein-cholesterol (LDL-C) level variability or long-term persistence with the monoclonal antibody evolocumab in routine clinical practice. HEYMANS (NCT02770131) is the first multi-country, multicenter, observational study of European patients initiating evolocumab as part of their routine clinical management, based on local reimbursement criteria (overall data recently published). The aim of this analysis is to describe clinical characteristics, baseline and changes in LDL-C levels, treatment patterns and persistence to evolocumab over 30 months in the Spanish cohort using data from the HEYMANS Registry. METHODS: HEYMANS was a prospective study of adult patients (≥18 years) who received at least one dose of evolocumab. A total of 1951 patients were enrolled from 12 countries and were followed up for 30 months after evolocumab initiation. Data were collected for 6 months before evolocumab initiation and up to 30 months thereafter. The Spanish cohort included patients who started evolocumab in routine clinical practice from March 2016 to September 2019. Demographic and clinical characteristics, lipid-lowering therapies (LLT), and lipid levels were collected. RESULTS: In total, 201 patients were included in the Spanish cohort. Median follow-up (Q1-Q3) was 30.0 (12-30) months. A total of 61.7% of patients were men and the mean (standard deviation) age was 59.5 (10.8) years. Most patients (68.7%) had experienced a prior cardiovascular event, 45.3% had coronary artery disease or stable angina, and 60.2% had a diagnosis of familial hypercholesterolemia. Overall, 57.7% of patients were receiving treatment with statins, most of them with high-intensity statins (85.3%); 45.8% of patients were intolerant to statins, and 26.4% of patients did not receive any LLT. At baseline, median (Q1-Q3) LDL-C levels were 151 (123-197) mg/dL. After 3 months of treatment, baseline LDL-C decreased by 66% to a median of 50 (30-83) mg/dL and these levels were maintained over time, with a median LDL-C of 55 (40-99) mg/dL at 30 months. At months 10-12 of treatment, LDL-C levels<55mg/dL were achieved by 56.3% of patients. LDL-C levels<70mg/dL were achieved by 70.1% of patients, and a lowering of LDL-C levels ≥50% was achieved by 76.8% of patients. The percentage of patients on evolocumab treatment was 95% at 12 months and 93% at 30 months. CONCLUSIONS: In the Spanish cohort in routine clinical practice, evolocumab therapy provided a reduction in LDL-C levels consistent with that reported in previous clinical trials, which was sustained during 30 months of follow-up. Treatment with evolocumab was started at LDL-C levels 50% higher than those recommended by The Spanish Society of Arteriosclerosis and the Therapeutic Positioning Report. The probability of achieving the 2019 ESC/EAS LDL-C goals would improve with combination therapy and also with a lower LDL-C threshold when starting evolocumab. Persistence to evolocumab remained high during follow-up, with a very low percentage of discontinuation (5% at 12 months; 7% at 30 months).

PURPOSE OF REVIEW: We describe the current status of lipid-lowering therapies for ischemic stroke prevention. The SPARCL trial published in 2006 has been a landmark study in vascular neurology. The trial demonstrated that high-dose atorvastatin prevents recurrent stroke, and led the AHA/ASA to recommend statin therapy for patients with stroke or TIA of atherosclerotic origin. RECENT FINDINGS: Recently, the J-STARS study demonstrated that therapy with low-dose pravastatin reduced atherothrombotic infarction incidence among patients with prior ischemic stroke. Besides, several trials have shown improved stroke outcomes with non-statin lipid-lowering medications: IMPROVE-IT with ezetimibe on top of simvastatin and PCSK9 inhibitors-FOURIER with evocolumab and ODYSSEY-OUTCOMES with alirocumab-on top of statin therapy. LDL-cholesterol remains the primary lipid treatment target for reduction of stroke risk. Randomized trials have shown that each reduction of 40 mg/dL in the level of LDL-cholesterol reduces the stroke risk by approximately one quarter, and further, reductions in LDL-cholesterol levels have shown to produce additional reductions in stroke risk. Currently, we have evidence of benefit for adding non-statin lipid-modifying therapies to statins to reduce stroke risk. Surely, these novel strategies to reduce residual lipidic risk will provide future benefits on stroke prevention.

Mujer de 55 años, obesa no diabética, remitida por su médico de atención primaria para estudio, de la unidad de lípidos de nuestro hospital, dedislipemia mixta sin control óptimo tras tratamiento con gemfibrozilo 900 mg al día. En la exploración clínica, la paciente presenta unos nódulos de consistencia blanda, móviles, no dolorosos a la palpación, de 1,2 × 0,8 cm el mayor de ellos, enmetacarpofalángicas y cara palmar de ambas manos, compatibles con xantomas tuberosos, sin otros hallazgos de interés. En el perfil bioquímico de factores de riesgo cardiovascular llamaba la atención un valor de cVLDL/TG de 0,38 (normal, hasta 0,27),lo cual nos puso en la pista del diagnóstico de una disbetalipoproteinemia. Realizamos una determinación del polimorfismo del gen de la ApoE, que nos confirmó que la paciente era portadora del genotipo E2/E2. Se llevó a cabo tratamiento con medidas dietéticas y atorvastatina 40 mg al día, con una notable mejoría de los valores lipídicos. Posteriormente, la paciente presentó un cuadro de claudicación intermitente, que llevó al diagnóstico de arteriopatía periférica severa (AU)
55-year old woman, obese, non-diabetic was referred by her primary care doctor for a study in the lipid unit of our hospital. She had mixed dyslipaemia which was not optimally controlled after treatment with 900 mg of gemfibrozil per day. In the clinical examination, the patient had soft, movable nodules, the largest of them being 1.2 ×0.8 cm, and painless on palpation, in the metacarpal phalanges and palms of both hands, compatible with tuberous xanthomas. There were no other findings of interest. The biochemical profile of cardiovascular risk factors highlighted ac-VLDL/TG value of 0.38 (normal up to 0.27),which led us to the diagnosis of adysbetalipo proteinemia. We performed apolymorphism analysis of the ApoE gene, which confirmed that the patient was a carrier of the E2/E2 genotype. Treatment was prescribed with dietetic measures and atorvastat in 40 mg per day, with a marked improvement in the lipid values. The patient later presented with a clinical picture of intermittent claudication, which was diagnosed as severe peripheral artery disease (AU)
