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)

Radiological aid to clinical diagnosis of Schnitzler's syndrome: multimodality imaging approach.

Schnitzler's syndrome is a rare combination of chronic urticaria, fever of unknown origin, disabling bone pain, and monoclonal gammopathy. We report a case with an unusual radiological manifestation as a solitary sclerotic lesion of the right iliac bone. Its main features on conventional radiography, computed tomography, and magnetic resonance imaging are described, and the main radiological differential diagnoses are discussed to help with the characterization of this syndrome, which requires a combination of clinical, laboratory, and radiological data. On the other hand, although our patient had an excellent clinical response to anakinra, the sclerotic lesion remained unchanged on follow-up X-ray examinations.
