Calcinosis cutis / Calcinosis cutis

Caso clínico: presentamos el caso de una mujer de 48 años con dolor en senos maxilares y zonas temporales, en la que se apreciaron placas cálcicas subcutáneas faciales al realizar una tomografía axial computarizada (TC). La exploración física y los datos del laboratorio fueron normales. Reinterrogando a la paciente, comentó que un año antes se le había administrado un producto de relleno facial que contiene hidroxiapatita cálcica (CaHA) (Radiesse®). Discusión: las microesferas de CaHA son radiopacas por lo que pueden observarse en las radiografías convencionales, y sobre todo en la TC. Las características de las imágenes, habitualmente bilaterales, separadas del hueso, junto con el antecedente de inyección previa de este material, debe orientar al clínico para reconocer este hallazgo y diferenciarlo de otras condiciones patológicas. Dada la popularidad que ha adquirido esta técnica de rejuvenecimiento facial, conviene que los clínicos conozcamos las características de las imágenes producidas por el depósito de esta sustancia. (AU)

Case report: we report the case of a 48-year-old woman with pain in the maxillary sinuses and temporal areas. The presence of subcutaneous facial calcific plaques was confirmed in computed tomography (CT). Both the physical examination and the lab test results were within normal limits. Upon further questioning, the patient mentioned that she had been administered a facial filler product containing calcium hydroxyapatite (CaHA) (Radiesse®) the year before. Discussion: CaHA microspheres are radiopaque, making them visible through conventional x-rays, especially CT scans. The characteristic imaging features, typically bilateral and separate from the bone, along with the history of previous injection of this material, should help the clinician recognize this finding and isolate it from other conditions and diseases. Because of the popularity of this facial rejuvenation technique, clinicians should be familiar with the imaging characteristics associated with the deposition of this substance. (AU)

Polygenic risk of bone fractures in Spanish women with osteoporosis / Riesgo poligénico de fracturas óseas en mujeres españolas con osteoporosis

Background: osteoporosis is a highly polygenic trait characterized by low bone mineral density (BMD) and/or fragility frac-tures. Over the past decade, polygenic risk scores (PRS) are an emerging tool to try to predict the risk of complex disorderswith a genetic component.Objective: to analyze the capacity of different PRSs to predict osteoporosis in the Spanish population.Material and methods: our dataset consisted of two differentiated groups. The first group included osteoporosis casesdiagnosed and treated at the Marques de Valdecilla University Hospital (n = 304; 293 women) while the second groupconsisted of people from the overall Spanish population (n = 3199; 1458 women). Four previously generated PRSs werecompared with generalized linear models.Results: the osteoporosis group showed a significantly higher genetic risk compared to the control group in 3 PRSs (PRS-1p = 1e-7; PRS-2 p = 1.87e-15; PRS-3 p = 0.1477; PRS-4 p = 8.98e-9). In addition, in these PRSs, the individuals in the upperquartile of risk had a significantly higher risk of osteoporosis, compared to those individuals in the other quartiles (PRS-1OR, 1.83; PRS-2 OR, 2.11; PRS-3 OR, 0.96; PRS-4 OR, 1.72).Conclusions: in summary, the application of PRSs shows significant differences between the overall Spanish populationand patients with osteoporosis, which is suggestive of its utility within strategies for the identification of subjects at riskbased on clinical-genetic criteria.(AU)

Romosozumab: confusión respecto a sus indicaciones / Romosozumab: confusion regarding its indications

El romosozumab es, sin duda, un excelente fármaco para el tratamiento de la osteoporosis. No obstante, su elevadoprecio, muy superior al de los fármacos antirresortivos, hizo que inicialmente se aceptara sin dificultad que su indicaciónse limitase a pacientes con un riesgo de fractura particularmente elevado. Sin embargo, la aplicación de esta idea en lapráctica se ha encontrado con algunos problemas. En primer lugar, para describir tal indicación se han utilizado términosdistintos (“riesgo muy alto”, “riesgo alto”, “osteoporosis grave”), el significado concreto de cada uno de los cuales,además, es diferente para unos y otros autores. Por otra parte, y sin un fundamento científico suficiente, se han idointroduciendo conceptos que pretenden ampliar las indicaciones del fármaco hasta prácticamente proponer la genera-lización de su uso (“riesgo inminente”, comienzo del tratamiento de la osteoporosis con anabólicos de forma universalo cuasi-universal). Todo ello ha generado confusión en el médico prescriptor, y ha dado lugar a que las autoridadessanitarias hayan impuesto para su uso normas que han resultado demasiado restrictivas. En el artículo se desarrollanestas ideas -y algunas otras- con detalle.(AU)

Long-Term Treatment and Effect of Discontinuation of Calcifediol in Postmenopausal Women with Vitamin D Deficiency: A Randomized Trial.

Vitamin D plays a major role in bone health and probably also in multiple extraskeletal acute and chronic diseases. Although supplementation with calcifediol, a vitamin D metabolite, has demonstrated efficacy and safety in short-term clinical trials, its effects after long-term monthly administration have been studied less extensively. This report describes the results of a 1-year, phase III-IV, double-blind, randomized, controlled, parallel, multicenter superiority clinical trial to assess the efficacy and safety of monthly calcifediol 0.266 mg versus cholecalciferol 25,000 IU (0.625 mg) in postmenopausal women with vitamin D deficiency (25(OH)D < 20 ng/mL). A total of 303 women were randomized and 298 evaluated. Patients were randomized 1:1:1 to calcifediol 0.266 mg/month for 12 months (Group A1), calcifediol 0.266 mg/month for 4 months followed by placebo for 8 months (Group A2), and cholecalciferol 25,000 IU/month (0.625 mg/month) for 12 months (Group B). By month 4, stable 25(OH)D levels were documented with both calcifediol and cholecalciferol (intention-to-treat population): 26.8 ± 8.5 ng/mL (Group A1) and 23.1 ± 5.4 ng/mL (Group B). By month 12, 25(OH)D levels were 23.9 ± 8.0 ng/mL (Group A1) and 22.4 ± 5.5 ng/mL (Group B). When calcifediol treatment was withdrawn in Group A2, 25(OH)D levels decreased to baseline levels (28.5 ± 8.7 ng/mL at month 4 versus 14.4 ± 6.0 ng/mL at month 12). No relevant treatment-related safety issues were reported in any of the groups. The results confirm that long-term treatment with monthly calcifediol in vitamin D-deficient patients is effective and safe. The withdrawal of treatment leads to a pronounced decrease of 25(OH)D levels. Calcifediol presented a faster onset of action compared to monthly cholecalciferol. Long-term treatment produces stable and sustained 25(OH)D concentrations with no associated safety concerns. © 2023 Faes Farma SA.

Aminobisfosfonatos: reconsideración a los 25 años de su aprobación para el tratamiento de la osteoporosis / Aminobisphosphonates: Reconsideration 25 years after their approval for the treatment of osteoporosis

Aminobisphosphonates are widely used in the treatment of osteoporosis. They have a high affinity for hydroxyapatite, binding primarily to resorbing surfaces, but also to forming surfaces and to some extent to resting surfaces. They inhibit osteoclasts, thereby decreasing remodelling units. Consequently, they increase bone mass and reduce stress risers. This decreases the risk of fractures. If this decrease is sufficient, they can be temporarily withdrawn (drug holidays), which prevents serious complications (atypical femoral fracture). They probably reduce mortality. Virtually all patients with osteoporosis can benefit from them at some point in the course of their disease (at the beginning of treatment or after the administration of anabolics, selective estrogen receptor modulators or denosumab). If well tolerated orally, alendronate and risedronate are preferable. Otherwise, zoledronate is preferred. Their efficacy vs. cost-safety-convenience ratio makes aminobisphosphonates reference drugs in the field of osteoporosis. (AU)

Los aminobisfosfonatos se utilizan ampliamente en el tratamiento de la osteoporosis. Tienen gran afinidad por la hidroxiapatita, uniéndose fundamentalmente a las superficies en resorción, pero también a las superficies en formación y, en cierta medida, a las superficies en reposo. Inhiben a los osteoclastos, con lo que disminuyen las unidades de remodelación. En consecuencia, aumentan la masa ósea y reducen los concentradores de tensión. Ello disminuye el riesgo de fracturas. Si esta disminución es suficiente, pueden retirarse transitoriamente (vacaciones terapéuticas), lo que previene complicaciones graves (fractura atípica de fémur). Probablemente disminuyen la mortalidad. Pueden beneficiarse de ellos prácticamente todos los enfermos con osteoporosis en algún momento de su evolución (al comienzo del tratamiento o tras la administración de anabólicos, moduladores selectivos de los receptores estrogénicos o denosumab). Con buena tolerancia oral son preferibles el alendronato y el risedronato. En caso contrario, lo es el zoledronato. Su relación eficacia frente a coste-seguridad-comodidad los convierte en fármacos de referencia en el campo de la osteoporosis. (AU)

Características Epidemiológicas y Clínicas de los Pacientes Nonagenarios Hospitalizados en un Servicio de Medicina Interna de un Hospital Terciario / Epidemiological and Clinical Characteristics of nonagenary patients hospitalized in an Internal Medicine Departament og A tertiary Hospital

Se presenta un estudio observacional retrospectivo de todos los pacientes mayores 90 ingresados en un Servicio de Medicina Interna durante el año 2017, siendo seguidos durante un año para recabar los datos de mortalidad. Se incluyeron 932 pacientes, con una media de edad de 93,1 años (67,6% mujeres). La mediana de la estancia resultó de 7 días. Un 21,7% fallecieron durante el ingreso hospitalario. El porcentaje de reingresos en los primeros 30 días tras el alta fue del 8,4% y la mortalidad al año fue del 55,3%. Los pacientes nonagenarios representan un alto porcentaje de los ingresos en un Servicio de Medicina Interna; sin embargo, su estancia hospitalaria fue similar a la del resto de los pacientes ingresados y el número de reingresos precoces fue bajo. Sin embargo, su mortalidad al año fue elevada, especialmente durante el primer mes tras el alta. (AU)

Retrospective observational study of 90 years patients or older who were admitted to an Internal Medicine Service during 2017. Also followed up for one year after going home to collect mortality data. 932 patients were included, with a mean age of 93.1 years (67.6% women). The median stay was 7 days. In-hospital mortality was 21.7%. Readmissions in the first 30 days after discharge was 8.4% and mortality at one year was 55.3%. Nonagenarian represent a high percentage of patients in an Internal Medicine Service. The hospital stay was similar to other patients and the number of early readmissions was low. However, the mortality at first year was high, especially during the first month after discharge. (AU)

Perfil lipídico y concentraciones séricas de ácido fólico, vitamina B12 y homocisteína en pacientes con obstrucción venosa retiniana / Lipid profile and serum folate, vitamin B12 and homocysteine levels in patients with retinal vein occlusion

Antecedentes: La obstrucción venosa retiniana (OVR) se relaciona fundamentalmente con los factores de riesgo vascular (FRV). Objetivos: Analizar el perfil lipídico y las concentraciones séricas de ácido fólico, vitamina B12 y homocisteína, en pacientes con OVR y un grupo control poblacional. Pacientes y métodos: Estudio de casos y controles. Los pacientes con OVR fueron estudiados a lo largo de un periodo de 11 años.Resultados: Se incluyeron 368 casos y 325 controles de similar edad y sexo. En los pacientes con OVR respecto a los controles, las concentraciones de HDL colesterol y de ácido fólico fueron menores (52 [43-63] mg/dL vs. 55 [46-66]; p = 0,016 y 7 [5-10] ng/mL vs. 9 [7-13]; p < 0,0001, respectivamente) y las de colesterol no HDL y de homocisteína fueron mayores (148,9 ± 37,3 mg/dL vs. 142,9 ± 3; p = 0,03 y 13,4 [11,2-18,2] μmol/L vs. 11,1 [9,0-14,4]; p < 0,0001). Aunque las cifras de colesterol total, cLDL y triglicéridos fueron mayores y las concentraciones de vitamina B12 fueron menores en los pacientes con OVR, estas diferencias no fueron significativas. Conclusiones: Los pacientes con OVR tienen concentraciones más bajas de colesterol HDL y de ácido fólico y cifras de colesterol no HDL y homocisteína más elevadas que los controles poblacionales de similar edad y sexo. En estos pacientes, además del perfil lipídico, podría ser útil la determinación de la homocisteína, el folato y la vitamina B12, así como el tratamiento de sus alteraciones.(AU)

Background: Retinal vein occlusion (RVO) is mainly related with vascular risk factors (VRF). Objectives: To analyze the lipid profile and serum folate, vitamin B12 and homocysteine levels, in patients with RVO and a population-based control group. Patients and Methods: Case-control study. Patients with RVO were assessed during an 11-year period. Results: We included 368 patients and 325 controls of similar age and sex. HDL cholesterol and folate levels were lower (52 [43-63] mg/dL vs. 55 [46-66]; p = 0.016 and 7 [5-10] ng/mL vs. 9 [7-13]; p < 0.0001, respectively) and non-HDL cholesterol and homocysteine levels higher (148.9 ± 37.3 mg/dL vs. 142.9 ± 34.5; p = 0.03 and 13.4 [11.2-18.2] μmol/L vs. 11.1 [9.0-14.4]; p < 0.001) in patients with RVO than controls. Although total cholesterol, LDL-C, and triglyceride levels were higher and serum vitamin B12 levels were lower in RVO patients, these differences did not reach statistical significance. Conclusions: RVO-patients have lower serum HDL-C and folate levels and higher non-HDL-C and serum homocysteine levels than population-based controls of similar age and sex. In patients with RVO, apart from the lipid profile, determination of serum homocysteine, folate and vitamin B12 levels might be useful, as well as the treatment of their alterations.(AU)

Multiple vertebral fractures after suspension of denosumab. A series of 56 cases.

BACKGROUND: Denosumab is a monoclonal antibody approved for the treatment of postmenopausal osteoporosis. The withdrawal of denosumab produces an abrupt loss of bone mineral density and may cause multiple vertebral fractures (MVF). OBJECTIVE: The objective of this study is to study the clinical, biochemical, and densitometric characteristics in a large series of postmenopausal women who suffered MVF after denosumab withdrawal. Likewise, we try to identify those factors related to the presence of a greater number of vertebral fractures (VF). PATIENTS AND METHODS: Fifty-six patients (54 women) who suffered MVF after receiving denosumab at least for three consecutive years and abruptly suspended it. A clinical examination was carried out. Biochemical bone remodelling markers (BBRM) and bone densitometry at the lumbar spine and proximal femur were measured. VF were diagnosed by magnetic resonance imaging MRI, X-ray, or both at dorsal and lumbar spine. RESULTS: Fifty-six patients presented a total of 192 VF. 41 patients (73.2%) had not previously suffered VF. After discontinuation of the drug, a statistically significant increase in the BBRM was observed. In the multivariate analysis, only the time that denosumab was previously received was associated with the presence of a greater number of VF (P = .04). CONCLUSIONS: We present the series with the largest number of patients collected to date. 56 patients accumulated 192 new VF. After the suspension of denosumab and the production of MVF, there was an increase in the serum values of the BBRM. The time of denosumab use was the only parameter associated with a greater number of fractures.

Calcifediol is superior to cholecalciferol in improving vitamin D status in postmenopausal women: a randomized trial.

Vitamin D has shown to play a role in multiple diseases due to its skeletal and extraskeletal actions. Furthermore, vitamin D deficiency has become a worldwide health issue. Few supplementation guidelines mention calcifediol treatment, despite being the direct precursor of calcitriol and the biomarker of vitamin D status. This 1-year, phase III-IV, double-blind, randomized, controlled, multicenter clinical trial assessed the efficacy and safety of calcifediol 0.266 mg soft capsules in vitamin D-deficient postmenopausal women, compared to cholecalciferol. Results reported here are from a prespecified interim analysis, for the evaluation of the study's primary endpoint: the percentage of patients with serum 25-hydroxyvitamin D (25(OH)D) levels above 30 ng/ml after 4 months. A total of 303 patients were enrolled, of whom 298 were included in the intention-to-treat (ITT) population. Patients with baseline levels of serum 25(OH)D <20 ng/ml were randomized 1:1:1 to calcifediol 0.266 mg/month for 12 months, calcifediol 0.266 mg/month for 4 months followed by placebo for 8 months, and cholecalciferol 25,000 IU/month for 12 months. At month 4, 35.0% of postmenopausal women treated with calcifediol and 8.2% of those treated with cholecalciferol reached serum 25(OH)D levels above 30 ng/ml (p < 0.0001). The most remarkable difference between both drugs in terms of mean change in serum 25(OH)D levels was observed after the first month of treatment (mean ± standard deviation change = 9.7 ± 6.7 and 5.1 ± 3.5 ng/ml in patients treated with calcifediol and cholecalciferol, respectively). No relevant treatment-related safety issues were reported in any of the groups studied. These results thus confirm that calcifediol is effective, faster, and more potent than cholecalciferol in raising serum 25(OH)D levels and is a valuable option for the treatment of vitamin D deficiency. © 2021 The Authors.

Repetición de las pruebas microbiológicas en la sospecha de la infección por SARS-CoV-2: utilidad de un score basado en la probabilidad clínica / Repetition of microbiological tests in suspect of SARS-CoV-2 infection: utility of a score based on clinical probability

INTRODUCCIÓN: El diagnóstico de la infección por SARSCoV-2 presenta limitaciones. La RT-PCR en frotis nasofaríngeo es la prueba considerada como el patrón oro, aunque puede ofrecer falsos negativos. El objetivo de este trabajo ha sido evaluar la utilidad de repetir el frotis nasofaríngeo en pacientes con resultado negativo en función de las diferentes probabilidades clínicas. MÉTODOS: Estudio observacional retrospectivo de los primeros pacientes ingresados en el Hospital Universitario Marqués de Valdecilla en dos plantas COVID de Medicina Interna durante marzo-abril del 2020. La RT-PCR para la detección de al menos dos dianas de los principales genes (E, N, RdRP, ORFab1) y el test de detección de anticuerpos para la detección de al menos IgG. RESULTADOS: Se analizaron 145 pacientes hospitalizados; 98 (67,5%) con el diagnóstico de SARS-CoV-2. Las variables predictivas independientes de SARS-CoV-2 fueron: contacto epidemiológico con otro paciente COVID-19, presentación clínica como neumonía, ausencia de neumonía en el año previo, inicio de síntomas >7 días al ingreso, ≥2 síntomas -tos, disnea y fiebre- y lactato deshidrogenasa >350 U/L (p < 0,05). Un score basado en estas variables presentó un área bajo la curva ROC (ABC ROC) de 0,89 (IC95 0,831-0,946; p < 0,001). El rendimiento de la RT-PCR en su primera determinación fue del 54,9%. La repetición de la prueba permitió detectar un 16% de casos adicionales. El rendimiento global de sucesivas RT-PCR en pacientes con baja probabilidad clínica fue inferior al 5%. CONCLUSIÓN: Hemos definido un score de probabilidad pre-prueba basado en datos epidemiológicos y clínicos con una buena precisión para el diagnóstico por infección SARSCoV-2. La repetición del frotis nasofaríngeo puede evitar errores de muestreo sólo en escenarios de intermedia-alta probabilidad clínica pre-prueba

BACKGROUND: The diagnosis of SARS-CoV-2 infection presents some limitations. RT-PCR in nasopharyngeal swabs is considered the gold standard for the diagnosis, although it can have false negative results. We aimed to analyze the accuracy of repeating nasopharyngeal swabs based on different clinical probabilities. METHODS: Retrospective observational study of the first patients admitted to a two COVID Internal Medicine wards at the University Hospital Marqués de Valdecilla, Santander, from March to April 2020. RT-PCR targering E, N, RdRP and ORFab1 genes and antibody tests detecting IgG. RESULTS: A total of 145 hospitalized patients with suspected SARS-Cov2 infection were admitted and in 98 (67.5%) diagnosis was confirmed. The independent predictive variables for SARS-CoV-2 infection were: epidemiological contact, clinical presentation as pneumonia, absence of pneumonia in the last year, onset of symptoms > 7 days, two or more of the following symptoms -dyspnea, cough or fever- and serum lactate dehydrogenase levels >350 U/L (p < 0.05). A score based on these variables yielded an AUC-ROC of 0.89 (CI95%, 0.831-0.946; p < 0.001). The accuracy of the first nasopharyngeal swabs was 54.9%. Repeating nasopharyngeal swabs two or three times allows to detect an additional 16% of positive cases. The overall accuracy of successive RT-PCR tests in patients with low pre-test probability was <5%. CONCLUSIONS: We have defined a pre-test probability score based on epidemiological and clinical data with a high accuracy for diagnosis of SARS-CoV-2. Repeating nasopharyngeal swabs avoids sampling errors, but only in medium of high probability pre-test clinical scenarios

Toxicidad grave por metotrexato en el anciano: nuestra experiencia en los últimos 7 años / Severe methotrexate toxicity in elderly: 7 years experience

El metotrexato es uno de los fármacos más empleados en pacientes con procesos reumatológicos, debido a su eficacia y perfil de seguridad. Sin embargo, los pacientes tratados con este fármaco son en ocasiones de edad avanzada, por lo que el riesgo de toxicidad aumenta, así como el de intoxicación por error en la toma de la medicación. Presentamos el caso de una paciente de 87 años, polimedicada, con antecedentes de deterioro cognitivo y escaso apoyo social que sufrió una intoxicación aguda grave por metotrexato. Además, describimos las características de los casos de toxicidad por este fármaco ingresados en nuestro Hospital en los últimos 7 años

Methotrexate is one of the most widely used drugs in rheumatology due to its high efficacy-to-toxicity. However, patients treated with this drug are sometimes elderly, which increases toxicity risks, as well as mistakes in taking the medication. The case is presented of an 87 year-old patient, on multiple medications, with a history of cognitive impairment and low social support, who suffered acute methotrexate toxicity. A description is also presented on the characteristics of the toxicity cases due this drug admitted to this hospital in the last 7 years

Interobserver agreement using Schlapbach graded scale for diffuse idiopathic skeletal hyperostosis (DISH): can we reduce the cut-off point of vertebral affection?

Resnick-Niwayama criteria for diagnosing DISH depict an advanced stage, and a new reduced cut-off point with three contiguous vertebrae affected (two bone bridges) has been proposed. The aim has been to know the interobserver agreement by using a graded scale of DISH in which grade II matches with the new proposed cut-off point and grade III matches with the first criterion of Resnick-Niwayama. Males ≥ 50 years and postmenopausal women included in a population-based prospective study (the Camargo Cohort) were analyzed. Sample size was obtained according to an expected kappa of 0.95 and an accuracy of ± 8%. Three physicians applied independently Schlapbach graded scale (ranged from grade 0, no ossification, to grade III, ≥ 3 consecutive bone bridges) on the lateral radiographs of thoracic and lumbar spine of participants. We calculated inter- and intra-observer agreement and correlation. One hundred and fifty eight radiographs (79 patients, 68 ± 9 years) were assessed. Kappa values (95% confidence interval) for grades 0, I, II, and III were 0.63 (0.50-0.77), 0.49 (0.37-0.62), 0.32 (0.17-0.47), and 0.69 (0.60-0.77), respectively. Weighted kappa for the three pairs of raters were 0.87 (0.82-0.93), 0.84 (0.77-0.91), and 0.81 (0.72-0.90). Grade III was the image that generated greater agreement, while a significant decrease was noted in grade II, the new proposed criterion. The simultaneous presence of an incomplete DISH and osteoarthritis, in a thoracic spinal segment with peculiar anatomical characteristics (reduced disk spaces, kyphotic curve), is thought to be a major cause of variability in the results.

Relación entre hiperostosis esquelética idiopática difusa, calcificación de la aorta abdominal y las alteraciones metabólicas asociadas: datos de la Cohorte Camargo / Relationship between diffuse idiopathic skeletal hyperostosis, abdominal aortic calcification and associated metabolic disorders: Data from the Camargo Cohort

Antecedentes y objetivo: La hiperostosis esquelética idiopática difusa (DISH, del inglés diffuse idiopathic skeletal hyperostosis) y la calcificación aórtica abdominal (CAA) se asocian a un incremento del riesgo cardiovascular. El objetivo fue analizar una posible relación entre ambas, así como las alteraciones metabólicas asociadas a la DISH. Pacientes y método: Estudio transversal-analítico, incluido en una cohorte poblacional. La DISH (criterios de Resnick-Niwayama) y la CAA (mediante la escala AAC-24) fueron evaluadas sobre imágenes de radiología simple. Se evaluaron asimismo otras 40 variables clínicas mediante correlaciones y regresión multivariante. Resultados: Fueron analizados 987 varones ≥ 50 años, con una edad media = 65, 5±9 años. Las prevalencias de DISH y CAA fueron del 21,6% y del 58,7%, respectivamente. El sujeto con DISH tenía mayor edad (68,1±9 vs. 63,8±9 años; p=0,0001) y con mayor frecuencia presentaba síndrome metabólico (SM) (55,6 vs. 36,6%; p=0,0001). La CAA fue de 3,7±5 puntos en sujetos con DISH frente a 3,3±5 en sujetos sin DISH (p=0,25), y se asoció a un riesgo incrementado de DISH prevalente (OR cruda=1,4 [IC95%: 1,01-1,9]; p=0,04), que desapareció al ajustar por edad (OR ajustada=1,1 [IC95%: 0,8-1,5]; p=0,47). No se observó asociación de la DISH con la hipertensión arterial, diabetes mellitus o dislipidemia, pero mantuvieron una relación significativa tras ajustar por confusores la edad (OR=2,2 [IC95%: 1,6-3]; p=0,0001), el IMC (OR=1,5 [IC95%: 1,1-2]; p=0,007), el perímetro abdominal (OR=1,5 [IC95%: 1,04-2,3]; p=0,03) y el SM (OR=1,7 [IC95%: 1,1-2,4]; p=0,005). Conclusiones: No se ha podido demostrar una asociación consistente entre la DISH y la CAA, presentando ambas una débil relación dependiente de la edad. La DISH ha mostrado unas asociaciones significativas con la edad, el IMC, el perímetro abdominal y el SM (AU)

Background and objective: Diffuse idiopathic skeletal hyperostosis (DISH) and abdominal aortic calcification (AAC) are related to an increased cardiovascular risk. The aim of this study was to analyse a possible relationship between both entities and also the association between metabolic disorders and DISH. Patients and method: Analytic cross-sectional study in a population-based cohort. DISH (with Resnick-Niwayama criteria) and AAC (with AAC-24 scale) were assessed on plain x-ray images. Interaction terms between DISH and forty clinical covariates were also investigated, through correlation analysis and multivariate regression. Results: Nine hundred eighty-seven males aged≥50 years, with a mean age=65,5±9 years, were evaluated. Prevalence rates of DISH and AAC were 21.6% and 58.7%, respectively. DISH+ subjects were older (68.1±9 vs. 63.8±9 years; P=.0001) and more likely to be affected by metabolic syndrome (MS) (55.6% vs. 36.6%; P=.0001). In DISH+ subjects, the AAC was 3.7±5 points, whereas in DISH− subjects it was 3.3±5 (P=.25). AAC was associated with an increased risk of prevalent DISH (unadjusted OR=1.4 [CI95%: 1.01-1.9]; P=.04), that disappeared when it was adjusted for age (adjusted OR=1.1 [CI95%: 0.8-1.5];P=.47]. No association was found between DISH and hypertension, diabetes or dyslipidaemia; however, age (OR=2.2 [CI95%: 1.6-3]; P=.0001), BMI (OR=1.5 [CI95%: 1.1-2]; P=.007), waist circumference (OR=1.5 [CI95%: 1.04-2,3]; P=.03) and MS (OR=1.7 [CI95%: 1.1-2.4]; P=.005) showed a significant relationship with DISH after adjusting for confounders. Conclusions: The study was not able to demonstrate a consistent association between DISH and AAC, proving only a weak and age-dependent relationship between them. DISH proved to be significantly associated with age, BMI, waist circumference and MS (AU)

Relationship between diffuse idiopathic skeletal hyperostosis, abdominal aortic calcification and associated metabolic disorders: Data from the Camargo Cohort. / Relación entre hiperostosis esquelética idiopática difusa, calcificación de la aorta abdominal y las alteraciones metabólicas asociadas: datos de la Cohorte Camargo.

BACKGROUND AND OBJECTIVE: Diffuse idiopathic skeletal hyperostosis (DISH) and abdominal aortic calcification (AAC) are related to an increased cardiovascular risk. The aim of this study was to analyse a possible relationship between both entities and also the association between metabolic disorders and DISH. PATIENTS AND METHOD: Analytic cross-sectional study in a population-based cohort. DISH (with Resnick-Niwayama criteria) and AAC (with AAC-24 scale) were assessed on plain x-ray images. Interaction terms between DISH and forty clinical covariates were also investigated, through correlation analysis and multivariate regression.

Relación entre la concentración plasmática de tirotropina y enfermedad cardiovascular (Cohorte Camargo) / Relationship between the plasmatic level of thyrotropin and cardiovascular disease (the Camargo Cohort)

Fundamentos y objetivo: La edad parece modificar la relación entre el hipotiroidismo y la enfermedad cardiovascular (ECV). Si bien en sujetos muy ancianos el hipotiroidismo se ha asociado a longevidad, en las personas de ≤65 años el hipotiroidismo subclínico parece relacionarse con un mayor riesgo cardiovascular (RCV). El objetivo del estudio ha sido conocer la capacidad explicativa de la tirotropina plasmática (TSHp) para la ECV en diferentes estratos de edad (≤55, 56-74, ≥75 años), sexo y factores de RCV. Pacientes y método: Un total de 664 varones y mujeres son diferenciados en 18 estratos. Mediante regresión lineal múltiple se elaboran los 18 modelos explicativos. La variable dependiente es la calcificación aórtica abdominal (CAA), según la escala AAC-24. Las variables independientes son: TSHp, edad, hábito tabáquico, índice de masa corporal, presión arterial sistólica, presión arterial diastólica, glucemia basal, colesterol total, colesterol unido a lipoproteínas de alta densidad, colesterol unido a lipoproteínas de baja densidad y proteína C reactiva. Resultados: La edad es la principal variable explicativa de CAA. El mayor valor del coeficiente β estandarizado de la TSHp se observa en varones≤55 años (β=0,235, p=0,043) y en mujeres≥75 años (β=0,405, p=0,042). Al incrementarse la edad, la capacidad explicativa de la TSHp para la CAA aumenta en las mujeres y disminuye en los varones. En varones≥75 años hay una correlación negativa entre TSHp y CAA (rho-Spearman=-0,213, p=0,049). Conclusiones: Se observa una asociación positiva entre la TSHp y ECV en varones≤55 años y en mujeres≥75 años. La combinación de la regresión múltiple y el análisis estratificado ha mostrado la compleja influencia de la edad en la relación entre ambas variables (AU)

Background and objective: Age seems to modify the relationship between hypothyroidism and cardiovascular disease (CVD). Although hypothyroidism in very elderly subjects has been associated with longevity, subclinical hypothyroidism in people≤65 years seems to be related with an increased cardiovascular risk (CVR). The aim of this study was to determine the explanatory power of plasmatic TSH (pTSH) for the CVD, in different strata determined by age (≤55, 56-74, ≥75 years), sex and CVR factors. Patients and methods: Six hundred and sixty-four men and women were differentiated into 18 strata and their explanatory models were developed using the multiple linear regression analysis. The dependent variable is the abdominal aortic calcification (AAC) according to the AAC-24 scale. The independent variables are: pTSH, age, smoking, BMI, SBP, DBP, fasting glucose, total cholesterol, HDL-cholesterol, LDL-cholesterol and C-reactive protein. Results: Age is the main explanatory factor of AAC. The highest explanatory value of the β-standardized coefficient of the pTSH is observed in males≤55 years (β=0.235, P=.043) and in females≥75 years (β=0.405, P=.042). With increasing age, the prediction power improves in women and decreases in men. In men≥75 years there is a negative correlation between pTSH and AAC (rho-Spearman=-0.213, P=.049). Conclusions: A positive association is observed between pTSH and CVD in males≤55 years and in women≥75 years. The combination of multiple regression and the stratified analysis shows the complex influence of age in the relation between both variables (AU)
