ABSTRACT

INTRODUCCIÓN: La esclerosis múltiple es una enfermedad inflamatoria y neurodegenerativa del sistema nervioso central, que afecta fundamentalmente a personas jóvenes en edad laboral y reproductiva, y que representa la primera causa de discapacidad no traumática en este rango etario de la población. Se reconoce un gradiente de latitud norte-sur, con un aumento de las tasas de prevalencia a medida que nos alejamos del ecuador. Este gradiente probablemente representa la predisposición genética transmitida desde las regiones escandinavas a través de las invasiones vikingas y podría presuponer una influencia del déficit de vitamina D en relación con un menor número de horas de sol anuales. OBJETIVO: Determinar la prevalencia e incidencia de la esclerosis múltiple en la ciudad de Ourense, Galicia. PACIENTES Y MÉTODOS: La ciudad de Ourense tiene una coordenada de latitud de 42° 34 N. Se ha realizado un estudio epidemiológico retrospectivo que abarca desde 2002 a 2016. La fecha de prevalencia fue el 31 de diciembre de 2016. El censo de la población de la ciudad de Ourense a 1 de enero de 2016 era de 105.892 habitantes. RESULTADOS: Se registraron 195 casos, lo que representa una prevalencia de 184,1 casos/100.000 habitantes. En el período 2002-2016 se diagnosticaron 127 casos de esclerosis múltiple, lo que supone una incidencia media de 7,86 casos/ 100.000 habitantes/año. CONCLUSIÓN: La ciudad de Ourense presenta la tasa de prevalencia de esclerosis múltiple más alta de las estudiadas hasta la actualidad en la Península Ibérica, con una cifra que la aproxima a los datos comunicados en áreas más septentrionales de influencia nórdica y anglosajona


INTRODUCTION: Multiple sclerosis is an inflammatory neurodegenerative disease of the central nervous system, which mainly affects young people of working and reproductive age, and represents the first cause of non-traumatic disability in this age group of the population. A north-south latitude gradient is recognised, with prevalence rates increasing as we move away from the equator. This gradient probably represents the genetic predisposition transmitted from the Scandinavian regions through the Viking invasions and could presuppose an influence of the vitamin D deficit related to a lower number of hours of sunshine per year. AIMS: To determine the prevalence and incidence of multiple sclerosis in the city of Ourense, Galicia. PATIENTS AND METHODS: The latitude coordinate of the city of Ourense is 42° 34 N. A retrospective epidemiological study covering the period from 2002 to 2016 was conducted. The prevalence date was 31 December 2016. According to the latest census, the population of the city of Ourense was 105,892 on 1 January 2016. RESULTS: Altogether, 195 cases were recorded, representing a prevalence of 184.1 cases/100,000 inhabitants. In the period 2002-2016, 127 cases of multiple sclerosis were diagnosed, representing an average incidence of 7.86 cases/100,000 inhabitants/year. CONCLUSION: The city of Ourense has the highest prevalence rate of multiple sclerosis of those studied to date in the Iberian Peninsula, with a figure that brings it closer to the data reported in more northern areas under Nordic and Anglo-American influence

ABSTRACT

Introducción. La fisiopatología del dolor en la migraña se relaciona con la activación del sistema trigeminovascular por medio de la liberación de neuropéptidos vasoactivos, y el más importante es el péptido relacionado con el gen de la calcitonina (CGRP), que causa una inflamación neurógena en los vasos leptomeníngeos. Objetivo. Investigar si el CGRP está incrementado en la migraña episódica frecuente y si el tratamiento preventivo con topiramato o zonisamida modifica sus niveles. Sujetos y métodos. Se estudiaron 28 pacientes con migraña episódica con o sin aura, cumpliendo los criterios de la Sociedad Internacional de Cefaleas, con una frecuencia de 4-14 días/mes. En todos los pacientes se determinaron los niveles plasmáticos del CGRP durante un período intercrítico (> 72 h sin dolor). Los pacientes se aleatorizaron en dos grupos de tratamiento, uno con 50 mg/día de topiramato y otro con 50 mg/día de zonisamida, durante tres meses. Al finalizar el período activo se analizó nuevamente el nivel del CGRP. El grupo control lo constituyeron nueve sujetos sanos. Resultados. El CGRP fue significativamente superior en el grupo de migraña episódica comparado con el grupo control (50,61 ± 22,5 pg/mL frente a 34,96 ± 17,03 pg/mL; p = 0,037). Después del tratamiento con neuromoduladores no se hallaron diferencias significativas en el nivel de CGRP (46,11 ± 24,2 pg/mL basal frente a 47,5 ± 24,88 pg/mL postratamiento). Tampoco se hallaron diferencias al analizar los grupos de topiramato y zonisamida de forma individualizada. Conclusiones. El nivel plasmático del CGRP está incrementado en la migraña episódica y sus niveles no son modificados por el tratamiento con dosis bajas de topiramato o zonisamida (AU)


Introduction. The pathophysiology of pain in migraine is related to the activation of the trigeminovascular system by releasing vasoactive neuropeptides, the most important of which is calcitonin gene-related peptide (CGRP), which causes a neurogenic inflammation in the leptomeningeal vessels. Aim. To study whether CGRP is increased in frequent episodic migraine and whether preventive treatment with topiramate or zonisamide modifies its levels. Subjects and methods. We studied 28 patients with episodic migraine with or without aura, in accordance with the International Headache Society criteria, with a frequency of 4-14 days/month. Plasma levels of CGRP were determined in all the patients during an interictal period (> 72 hours without pain). Patients were divided at random into two treatment groups, one with 50 mg/day of topiramate and the other with 50 mg/day of zonisamide, for three months. At the end of the active period the CGRP level was analysed again. The control group consisted of nine healthy subjects. Results. CGRP was significantly higher in the episodic migraine group than in the control group (50.61 ± 22.5 pg/mL versus 34.96 ± 17.03 pg/mL; p = 0.037). After treatment with neuromodulators no significant differences were found in the level of CGRP (46.11 ± 24.2 pg/mL basal versus 47.5 ± 24.88 pg/mL post-treatment). Neither were any differences found on analysing the topiramate and zonisamide groups individually. Conclusions. The plasma level of CGRP is increased in episodic migraine, and its levels are not modified by treatment with low doses of topiramate or zonisamide (AU)
