ABSTRACT

The relationship between vitamin D deficiency and the risk of suffering from a plethora of health disorders, ranging from autoimmune processes to infectious diseases has been widely described. Nonetheless, the potential role of vitamin D in visceral leishmaniasis remains uncharacterized. In the Mediterranean basin, where the dog is leishmania's main peri-domestic reservoir, control measures against the canine disease have shown beneficial effects on the incidence of human leishmaniasis. In this study, we measured the vitamin D levels in serum samples from a cohort of 68 healthy and disease dogs from a highly endemic area and we have also studied the relationship of these levels with parasitological and immunological parameters. The sick dogs presented significantly lower (P < 0.001) vitamin D levels (19.6 ng/mL) than their non-infected (31.8 ng/mL) and the asymptomatic counterparts (29.6 ng/mL). In addition, vitamin D deficiency correlated with several parameters linked to leishmaniasis progression. However, there was no correlation between vitamin D levels and the Leishmania-specific cellular immune response. Moreover, both the leishmanin skin test and the IFN-γ levels displayed negative correlations with serological, parasitological and clinical signs. Further studies to determine the functional role of vitamin D on the progression and control of canine leishmaniasis are needed.

ABSTRACT

Las lesiones medulares, en función de su etiología, se pueden dividir en dos grandes grupos que incluirían las de causa traumática (responsables del 70 por ciento de las paraplejías adquiridas del adulto) y las de causa médica, incluyendo en este segundo grupo, la patología propia de la médula (tumores, infecciones, esclerosis en placas, lesiones vasculares) y la patología derivada de una compresión extrínseca (epiduritis infecciosa o neoplásica, tumor o parasitosis ósea y espondilodiscitis). La patología vascular medular es menos frecuente que la cerebral, siendo su incidencia real desconocida. La forma habitual de presentación clínica es una tetra- o paraplejía flácida de comienzo brusco, frecuentemente con dolor por debajo del nivel de la lesión, pérdida de la sensibilidad infralesional y afectación de la función esfinteriana. Presentamos el caso clínico de un paciente con una paraplejía completa secundaria a una hemorragia medular en el contexto probable de un Síndrome de Klippel-Trenaunay-Weber, proceso poco frecuente caracterizado por la presencia de malformaciones vasculares en una extremidad, junto con una hipertrofia de los tejidos blandos y/o óseos y lesiones cutáneas (AU)
