Improved lipid-lowering treatment and reduction in cardiovascular disease burden in homozygous familial hypercholesterolemia: The SAFEHEART follow-up study.

AIM: We aimed to describe clinical and genetic characteristics, lipid-lowering treatment and atherosclerotic cardiovascular disease (ASCVD) outcomes over a long-term follow-up in homozygous familial hypercholesterolemia (HoFH). METHODS: SAFEHEART (Spanish Familial Hypercholesterolaemia Cohort Study) is a long-term study in molecularly diagnosed FH. Data analyzed in HoFH were prospectively obtained from 2004 until 2022. ASCVD events, lipid profile and lipid-lowering treatment were determined. RESULTS: Thirty-nine HoFH patients were analyzed. The mean age was 42 ± 20 years and nineteen (49%) were women. Median follow-up was 11 years (IQR 6,18). Median age at genetic diagnosis was 24 years (IQR 8,42). At enrolment, 33% had ASCVD and 18% had aortic valve disease. Patients with new ASCVD events and aortic valve disease at follow-up were six (15%), and one (3%), respectively. Median untreated LDL-C levels were 555 mg/dL (IQ 413,800), and median LDL-C levels at last follow-up was 122 mg/dL (IQR 91,172). Most patients (92%) were on high intensity statins and ezetimibe, 28% with PCSK9i, 26% with lomitapide, and 23% with lipoprotein-apheresis. Fourteen patients (36%) attained an LDL-C level below 100 mg/dL, and 10% attained an LDL-C below 70 mg/dL in secondary prevention. Patients with null/null variants were youngers, had higher untreated LDL-C and had the first ASCVD event earlier. Free-event survival is longer in patients with defective variant compared with those patients with at least one null variant (p=0.02). CONCLUSIONS: HoFH is a severe life threating disease with a high genetic and phenotypic variability. The improvement in lipid-lowering treatment and LDL-C levels have contributed to reduce ASCVD events.

INTRODUCTION: Aim: to communicate the home parenteral nutrition (HPN) data obtained from the HPN registry of the NADYA-SENPE group (www.nadya-senpe.com) for the year 2019. Material and methods: a descriptive analysis of the data collected from adult and pediatric patients with HPN in the NADYA-SENPE group registry from January 1 to December 31, 2019. Results: a total of 283 patients (51.9 % women), 31 children, and 252 adults from 47 Spanish hospitals were registered, which represents a prevalence rate of 6.01 patients per million inhabitants for year 2019. The most frequent diagnosis in adults was "palliative oncological" and "others" (21.0 %). In children, it was Hirschsprung's disease together with necrotizing enterocolitis, alterations in intestinal motility, and chronic intestinal pseudo-obstruction, with 4 cases each (12.9 %). The first reason for the indication was short-bowel syndrome in both children (51.6 %) and adults (37.3 %). The most used type of catheter was tunnelled both in children (75.9 %) and in adults (40.8 %). Sixty-eight episodes ended, all in adults, and the most frequent cause was death (54.4 %); 38.2 % were switched to oral. Conclusions: the number of collaborating centers and professionals in the NADYA registry is increasing. The main indications and reasons for HPN termination remain stable.

In vitro Selection of Probiotics for Microbiota Modulation in Normal-Weight and Severely Obese Individuals: Focus on Gas Production and Interaction With Intestinal Epithelial Cells.

The intestinal microbiota plays important roles in the maintenance of health. Strategies aiming at its modulation, such as probiotics, have received a deal of attention. Several strains have been studied in different in vitro models; however, the correlation of results obtained with the in vivo data has been limited. This questions the usefulness of such in vitro selection models, traditionally relying on over-simplified tests, not considering the influence of the accompanying microbiota or focusing on microbiota composition without considering functional traits. Here we assess the potential of six Bifidobacterium, Lactobacillus and Lacticaseibacillus strains in an in vitro model to determine their impact on the microbiota not just in terms of composition but also of functionality. Moreover, we compared the responses obtained in two different population groups: normal-weight and severely obese subjects. Fecal cultures were conducted to evaluate the impact of the strains on specific intestinal microbial groups, on the production of short-chain fatty acids, and on two functional responses: the production of gas and the interaction with human intestinal epithelial cells. The response to the different probiotics differed between both human groups. The addition of the probiotic strains did not induce major changes on the microbiota composition, with significant increases detected almost exclusively for the species added. Higher levels of gas production were observed in cultures from normal-weight subjects than in the obese population, with some strains being able to significantly reduce gas production in the latter group. Moreover, in obese subjects all the Bifidobacterium strains tested and Lacticaseibacillus rhamnosus GG were able to modify the response of the intestinal cells, restoring values similar to those obtained with the microbiotas of normal-weight subjects. Our results underline the need for the screening and selection of probiotics in a target-population specific manner by using appropriate in vitro models before enrolling in clinical intervention trials.

Impact of Extreme Obesity and Diet-Induced Weight Loss on the Fecal Metabolome and Gut Microbiota.

SCOPE: A limited number of human studies have characterized fecal microbiota and metabolome in extreme obesity and after diet-induced weight loss. METHODS AND RESULTS: Fecal samples from normal-weight and extremely obese adults and from obese participants before and after moderate diet-induced weight loss are evaluated for their interaction with the intestinal adenocarcinoma cell line HT29 using an impedance-based in vitro model, which reveals variations in the interaction between the gut microbiota and host linked to obesity status. Microbiota composition, short chain fatty acids, and other intestinal metabolites are further analyzed to assess the interplay among diet, gut microbiota, and host in extreme obesity. Microbiota profiles are distinct between normal-weight and obese participants and are accompanied by fecal signatures in the metabolism of biliary compounds and catecholamines. Moderate diet-induced weight loss promotes shifts in the gut microbiota, and the primary fecal metabolomics features are associated with diet and the gut-liver and gut-brain axes. CONCLUSIONS: Analyses of the fecal microbiota and metabolome enable assessment of the impact of diet on gut microbiota composition and activity, supporting the potential use of certain fecal metabolites or members of the gut microbiota as biomarkers for the efficacy of weight loss in extreme obesity.

Incidence of cardiovascular events and changes in the estimated risk and treatment of familial hypercholesterolemia: the SAFEHEART registry.

INTRODUCTION AND OBJECTIVES: The SAFEHEART study was designed to analyze the situation of familial heterozygous hypercholesterolemia (FHH) and improve knowledge of this disease in Spain. Our objective was to determine the incidence rate of cardiovascular events, the estimated risk of developing an event and its modification, the use of lipid-lowering treatment, and the achievement of low-density lipoprotein cholesterol targets in patients with FHH. METHODS: SAFEHEART is a prospective, open, multicenter, nationwide cohort study, with long-term protocol-based follow-up in a population of individuals with molecularly-characterized FHH. We analyzed patients older than 18 years with complete follow-up. RESULTS: We included 2648 patients with FHH. The median follow-up was 6.6 (4.8-9.7) years. The overall incidence rate of cardiovascular events was 1.3 events/100 patient-years. After the follow-up, the 10-year estimated risk of developing a cardiovascular event was reduced from 1.6% to 1.3% (P <.001). In the last follow-up, 20.6% and 22.2% of the patients in primary and secondary prevention achieved low-density lipoprotein cholesterol values <100mg/dL and <70mg/dL, respectively. CONCLUSIONS: This study was performed in the largest population of patients with FHH in Spain. We identified the incidence rate of cardiovascular events, the estimated risk of developing a cardiovascular event and its modification, the achievement of low-density lipoprotein cholesterol targets, and the therapeutic management in this population. Although the cardiovascular risk of FHH is high, appropriate treatment reduces the likelihood of an event. CLINICAL TRIAL REGISTRATION: http://www.clinicaltrials.gov. Identifier: NCT02693548.

[Not Available]. / Teduglutida: revisión de su uso en el síndrome de intestino corto.

Introducción:la nutrición parenteral (NP) a largo plazo puede asociarse a complicaciones graves, con un deterioro importante de la calidad de vida de los pacientes con síndrome de intestino corto (SIC). Teduglutida, un análogo del péptido-2 similar al glucagón, pertenece a una nueva familia terapéutica y representa el primer abordaje no sintomático del SIC. Objetivos: revisar los datos preclínicos y clínicos en cuanto a eficacia y seguridad de teduglutida. Resultados: la aprobación de teduglutida se basó en los resultados de un estudio en fase III de 24 semanas, doble ciego, controlado con placebo (STEPS). Pacientes con fallo intestinal por SIC dependientes de NP ≥ 3 veces/semana durante ≥ 12 meses recibieron 0,05 mg/kg de teduglutida (n = 43) o placebo (n = 43) 1 vez/día. En la semana 24 hubo significativamente más respondedores en el grupo de teduglutida que en el de placebo (63 vs.30%; p = 0,002). La reducción absoluta media del volumen de NP frente al valor basal en la semana 24 fue significativamente mayor con teduglutida (4,4 vs.2,3 l/semana; p < 0,001). La necesidad de NP se redujo ≥ 1 día en la semana 24 en el 54% de pacientes tratados con teduglutida vs.23% con placebo. Del total de pacientes que recibieron teduglutida en los ensayos en fase III (n = 134), el 12% consiguió una autonomía completa de la NP. Por lo general, la administración subcutánea de teduglutida se toleró bien. Conclusiones: se ha demostrado que teduglutida recupera la absorción intestinal y reduce significativamente la dependencia de la NP, consiguiendo incluso la independencia en algunos pacientes.

Attainment of LDL-Cholesterol Treatment Goals in Patients With Familial Hypercholesterolemia: 5-Year SAFEHEART Registry Follow-Up.

BACKGROUND: Familial hypercholesterolemia (FH) is the most common genetic disorder associated with premature atherosclerotic cardiovascular disease (ASCVD). There are sparse data on attainment of treatment targets; large registries that reflect real-life clinical practice can uniquely provide this information. OBJECTIVES: We sought to evaluate the achievement of low-density lipoprotein cholesterol (LDL-C) treatment goals in FH patients enrolled in a large national registry. METHODS: The SAFEHEART study (Spanish Familial Hypercholesterolemia Cohort Study) is a large, ongoing registry of molecularly defined patients with heterozygous FH treated in Spain. The attainment of guideline-recommended plasma LDL-C goals at entry and follow-up was investigated in relation to use of lipid-lowering therapy (LLT). RESULTS: The study recruited 4,132 individuals (3,745 of whom were ≥18 years of age); 2,752 of those enrolled were molecularly diagnosed FH cases. Mean follow-up was 5.1 ± 3.1 years; 71.8% of FH cases were on maximal LLT, and an LDL-C treatment target <100 mg/dl was reached by only 11.2% of patients. At follow-up, there was a significant increase in the use of ezetimibe, drug combinations with statins, and maximal LLT. The presence of type 2 diabetes mellitus, a defective allele mutation, ezetimibe use, and the absence of previous ASCVD were predictors of the attainment of LDL-C goals. CONCLUSIONS: Despite the use of intensified LLT, many FH patients continue to experience high plasma LDL-C levels and, consequently, do not achieve recommended treatment targets. Type of LDL-receptor mutation, use of ezetimibe, coexistent diabetes, and ASCVD status can bear significantly on the likelihood of attaining LDL-C treatment goals.

AIM: to communicate the results of the Spanish Home Parenteral Nutrition (HEN) registry of the NADYASENPE group for the year 2014. MATERIAL AND METHODS: data was recorded online by NADYA group collaborators that were responsible of the HPN follow-up from 1st January to 31st December 2014. RESULTS: a total of 220 patients and 229 episodes of HPN were registered from 37 hospitals that represents a rate of 4.7 patients/million habitants/year 2014. The most frequent disease in adults was other diseases (23.3%), neoplasm (20.4%) followed by radical active neoplasm (11.8%) and mesenteric ischemia (10.9%). The most frequent diagnosis for children were the congenital intestinal disorders (33.3%) followed by traumatic short bowel and other diagnosis. CONCLUSIONS: the number of participating centers and registered patients increased progressively respect to preceding years. We consider that the HPN should be regulated by the Sanitary Administration within the framework of the National Health Service Interregional Council. And its inclusion in the portfolio of health services of the different Autonomous Comunities would be beneficial for patients and professionals.

Resultados: se registraron 220 pacientes, con 229 episodios de NPD, procedentes de 37 hospitales; lo que representa una tasa de 4,73 pacientes/millón de habitantes/ año 2014. Las patologías más frecuentes en los adultos fueron: 'otros diagnósticos' (22,3%), la neoplasia paliativa (20,4%), seguida por la neoplasia activa radical (11,8%) y la isquemia mesentérica (10,9%). En los niños las patologías más frecuentes fueron: 'alteraciones congénitas intestinales' (33,3%), seguidas por 'intestino corto traumático' y 'otro diagnóstico'. Conclusiones: se observa un aumento del número de pacientes que reciben nutrición parenteral domiciliaria y de los centros colaboradores. Consideramos que la NPD debería ser regulada por la Administración Sanitaria en el marco del Consejo Interterritorial del Sistema Nacional de Salud, y que su inclusión en la Cartera de Servicios de los diferentes Servicios de Salud de las diferentes comunidades autónomas redundaría en un beneficio para el paciente y los profesionales.

A Home and Ambulatory Artificial Nutrition (NADYA) group report, Home Parenteral Nutrition in Spain, 2013.

AIM: To communicate the results of the Spanish Home Parenteral Nutrition (HPN) registry of the NADYA-SENPE group for the year 2013. MATERIAL AND METHODS: Data was recorded online by NADYA group collaborators that were responsible of the HPN follow-up from 1st January to 31st December 2013. RESULTS: A total of 197 patients and 202 episodes of HPN were registered from 35 hospitals that represents a rate of 4,22 patients/million habitants/year 2013. The median age was 53 years (IQR 40-64) for 189 adult patients and 7 months (IQR 6-35,5) for children. The most frequent disease in adults was neoplasm (30,7%) followed by other diseases (20,1%) and mesenteric ischemia (12,7%). Short bowel syndrome and intestinal obstruction (25,9%) were in 35.7% cases the indications for HPN. The most frequent diagnosis for children were the congenital intestinal disorders and other diagnosis, both with a (37,5%) and short bowel syndrome and intestinal obstruction were the indication for treatment, each was present in 50% of the sample. Tunneled catheters (50%) and subcutaneous reservoirs (27,7%) were frequently used. The septic complications related with catheter were commonly frequent with a rate of 0.74 infections/1000 HPN days. HPN duration presented a median of 1,69 days. A total of 86 episodes finalized during the year, death was the principal reason (45%), followed by "resumed oral via" (43,75%) while it happened inversely for children, 66,7% of them resumed oral via and 16,7% deceased. Fifteen per cent were considered for intestinal transplant, children were proportionally candidates, p-value 0.002. CONCLUSIONS: The number of participating centers and registered patients increased progressively respect to preceding years. Since 2003 Neoplasm is still being the principal pathological group. Death is adult's principal reason for finalizing HPN and "resuming oral via" for children. Despite that NADYA registry is consolidate as a essential source of relevant information about the advances in Home Artificial Nutrition in our country, currently is in an improvement process of the available information about patients characteristics with a special emphasis on children even though they still being a minority group.

Objetivo: comunicar los datos del registro de Nutrición Parenteral Domiciliaria (NPD) del grupo de trabajo NADYA-SENPE del años 2013. Material y métodos: recopilación de los datos del registro "on-line" introducidos por los colaboradores del grupo NADYA responsables del seguimiento de la NPD desde el 1 de enero de 2013 al 31 de diciembre de 2013. Resultados: se registraron 197 pacientes, procedentes de 35 hospitales, lo que representa una tasa de 4,22 pacientes/ millón habitantes/año 2013, con 202 episodios de NPD. La edad media de los 189 pacientes mayores de 14 años fue de 53 años (IIQ 40 ­ 64), y en los niños de 7 meses (IIQ 6 ­ 35,5). La patología más frecuente en los adultos fue la neoplasia (30,7%) seguida por otras patologías (20,1%) y la isquemia mesentérica (12,7%). En el 35,4% de los casos el motivo de indicación fue el síndrome de intestino corto, seguido de la obstrucción intestinal (25,9%). En los niños el diagnóstico más frecuente fueron las alteraciones congénitas intestinales y 'otros diagnósticos', ambas con un 37,5 %, y la causa de la indicación el síndrome de intestino corto y la obstrucción intestinal, que se repartieron el 50% de la muestra. Los catéteres más utilizados fueron los tunelizados (50%) y los reservorios subcutáneos (27,7%). Las complicaciones más frecuentes fueron las sépticas, relacionadas con el catéter, con una tasa de 0,74 infecciones/1.000 días de NPD. La duración de la NPD presentó una mediana de 1,69 años. Durante el año finalizaron 86 episodios, la principal causa de la finalización en adultos fue el fallecimiento (45%) seguido del 'paso a la vía oral' (43,75%) y en los niños a la inversa 66,7% pasan a vía oral y 16,7% fallecen. Se consideraron candidatos para trasplante intestinal el 15% de los pacientes, siendo proporcionalmente los candidatos niños, p-valor 0,002. Conclusiones: se observa un aumento progresivo de los centros participantes y de los pacientes registrados respecto a años anteriores. El principal grupo patológico sigue siendo oncológico, ocupando el primer lugar desde 2003. La principal causa de finalización de la NPD es en los adultos el fallecimiento y en los niños el 'paso a vía oral'. Aunque el registro NADYA es un registro consolidado y ha sido y es fuente imprescindible de información relevante para el conocimiento de los avances de la Nutrición Artificial Domiciliaria en nuestro país, se encuentra en proceso de mejorar la información que ofrece sobre las características de los pacientes, con especial atención en el grupo de niños, aunque estos siguen siendo un número reducido.

[Chylous asctites post abdominal laparotomy; revision and report of a case]. / Ascitis quilosa postlaparoscopia abdominal; revisión y descripción de un caso.

We describe the case of a 23 year old man who had undergone laparoscopic surgery in order to remove a residual mass secondary to a testicular embryonal carcinoma. 15 days after he attended the emergency department complaining about abdominal bloating and copious drainage via the two laparoscopic surgery incisions. Biochemical analysis was consistent with chylous ascites. Although this is uncommon, it is well known that there is more likely to develop chylous ascites after oncologic surgery if retroperitoneal lymph nodes dissection is performed1. We decide to start with conservative treatment (dietary modifications) but, as it is not enough, then we decide stop any oral intake and treat him with parenteral nutrition, achieving then total resolution of the ascites.

Describimos el caso de un varón de 23 años operado mediante laparoscopia de una masa residual secundaria a un carcinoma embrionario testicular. 15 días después acude al servicio de Urgencias por distensión abdominal y drenaje de líquido lechoso por las dos incisiones de la cirugía laparoscópica. Tras el análisis bioquímico del líquido que reflejaba un aumento de triglicéridos se llegó al diagnóstico de ascitis quilosa. Aunque es infrecuente, se describe que existe mayor probabilidad de ascitis quilosa después de cirugías oncológicas si se lleva a cabo la disección de ganglios linfáticos retroperitoneales1. Se decide tratamiento conservador inicialmente con modificaciones dietéticas y posteriormente con nutrición parenteral, con resolución total de la ascitis.

Genetic diagnosis of familial hypercholesterolemia using a DNA-array based platform.

OBJECTIVES: The aim of this study was to validate the Lipochip genetic diagnostic platform by assessing effectiveness, sensitivity, specificity and costs for the identification of patients with familial hypercholesterolemia (FH) in Spain. This platform includes the use of a DNA micro array, the detection of large gene rearrangements and the complete resequencing of the low-density lipoprotein receptor gene. DESIGN AND METHODS: DNA samples of patients with clinically diagnosed FH were analyzed for mutations by application of the Lipochip platform. Results obtained were confirmed by DNA sequencing and MLPA analysis by two other, independent laboratories. RESULTS: Of 808 patients tested, Lipochip detected a mutation in 66% of the cases and of these 78% were detected by the micro array. A specificity of 99.5% at a sensitivity of 99.8% was reached. A positive test result could be reported within 22 days after start of analysis. The total average screening costs of $350 per case were significantly lower compared to other existing screening programs. CONCLUSION: Lipochip provides a reliable, fast and cheap alternative for the genetic testing of patients with clinically diagnosed FH.
