Prevalence of Neuropathic Pain in Patients with Osteoarthritis / Prevalência de dor neuropática em pacientes com osteoartrite

Abstract Objective The aim of this study was to determine the prevalence of neuropathic pain and characterize the quality of life of patients with osteoarthritis who consulted a pain clinic in Southwestern Colombia. Methods A cross-sectional study was conducted via telephone survey. Participants ≥18 years of age with a diagnosis of osteoarthritis were included. The LANSS questionnaire was used to evaluate symptoms and signs of neuropathic pain, and the Short Form-8 was used to evaluate quality of life. Results Response rate was 54.1% (46/85). The male-to-female ratio was 5:1, with an average age of 72 ±10 years. Most participants (91.3%) had severe pain. The prevalence of neuropathic pain was 28.3% (95%CI = 15.99-43.46), and the prevalence of neuropathic pain amongst women was 84.6% (95%CI = 54.55-98.01 ). Dysesthesias and paroxysmal pain were present in 92.3% of individuals with neuropathic pain. Regarding quality of life, limitations in physical activity were the most significant, as 63% of individuals reported such limitations. Conclusion Neuropathic pain was found to be prevalent and had a negative impact on physical function, highlighting the need for therapeutic strategies targeted to specific neuropathic pain pathways in patients with osteoarthritis.

Resumo Objetivo O objetivo deste estudo foi determinar a prevalência de dor neuropática e caracterizar a qualidade de vida de pacientes com osteoartrite que consultaram um ambulatório de dor no sudoeste da Colômbia. Métodos Este foi um estudo transversal realizado por meio de entrevista telefônica. Foram incluídos participantes ≥18 anos de idade com diagnóstico de osteoartrite. O questionário Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) foi utilizado para avaliação dos sintomas e sinais de dor neuropática e o Short Form-8 analisou a qualidade de vida. Resultados A taxa de resposta foi de 54,1% (46/85). A razão homem:mulher foi de 5:1, com média de idade de 72 ±10 anos. A maioria dos participantes (91,3%) apresentava dor intensa. A prevalência de dor neuropática foi de 28,3% (intervalo de confiança [IC] de 95% = 15,99-43,46) e a prevalência de dor neuropática entre mulheres foi de 84,6% (IC 95% = 54,55-98,01). Disestesias e dor paroxística foram relatadas por 92,3% dos indivíduos com dor neuropática. Em relação à qualidade de vida, as limitações na prática de atividade física foram as mais significativas e relatadas por 63% dos indivíduos. Conclusão A dor neuropática foi prevalente e tinha impacto negativo na função física. Isso destaca a necessidade de estratégias terapêuticas direcionadas a vias específicas da dor neuropática em pacientes com osteoartrite.

Physical activity in a rural community in Colombia / Actividad física en una comunidad rural de Colombia

ABSTRACT Objective To characterize physical activity profiles in a rural community in the southwest of Colombia and to identify knowledge gaps on this issue in the country. Methods Cross-sectional study conducted in a rural area in Puerto Caldas, Pereira, Risaralda. The population of the study was obtained by convenience sampling from people participating in the activities of the Second Multidisciplinary Camp for Research and Services (CUMIS, for its acronym in Spanish), which was organized by the Colombian Association of Medical Students' Scientific Societies (ASCEMCOL, for its acronym in Spanish). The International Physical Activity Questionnaire (IPAQ) was used in order to measure and classify the physical activity behaviors of this population. Results Data from 100 subjects with a mean age of 43±18 years were collected. 6 % of the population did not perform any kind of physical activity, while 61 % performed vigorous physical activity. Men spent more time in doing vigorous and moderate physical activity than women did (p<0.05). The World Health Organization (WHO) recommendations on physical activity were followed by 72.29 % (n=60) and 82.35 % (n=14) of the people with an age of 18 to64 and ≥65 years, respectively. Conclusion It is necessary to build up evidence regarding physical activity in rural areas in order to implement public policies that promote its practice in communities where socioeconomic and health inequities exist. Part of the population living in the community where the study was carried out does not follow the WHO recommendations on physical activity; therefore, the lack of public health interventions is highlighted. A better coherence between international resolutions, national public policies and their implementation could lead to an increase in practice levels of physical activity.(AU)

RESUMEN Objetivo Caracterizar la actividad física en una comunidad rural del suroeste de Colombia e identificar los vacíos de conocimiento alrededor del tema en el país. Métodos Estudio de corte transversal en una zona rural de Puerto Caldas, Pereira, Risaralda. La población fue seleccionada, mediante muestreo por conveniencia, entre las personas que participaron en las actividades del II Campamento Multidisciplinar de Investigación y Servicios (CUMIS), dirigido por la Asociación Colombiana de Sociedades Científicas de Estudiantes de Medicina (ASCEMCOL). Se utilizó el International Physical Activity Questionnaire (IPAQ) para medir y clasificar los comportamientos de esta población en términos de actividad física. Resultados Se recogieron datos de 100 sujetos con edad promedio de 43±18 años. El 6 % de la población no realizó ningún tipo de actividad física, mientras que el 61 % realizó actividad física vigorosa. Los hombres dedicaron más tiempo a la práctica de actividad física vigorosa y moderada que las mujeres (p<0,05). Las recomendaciones sobre actividad física de la Organización Mundial de la Salud (OMS) fueron seguidas por el 72,3 % (n=60) y el 82,4 % (n=14) de las personas en los grupos de edad de 18 a 64 y ≥65 años, respectivamente Conclusión Es necesario construir evidencia en torno a la actividad física en el área rural, a fin de implementar políticas públicas que promuevan su práctica en comunidades que presenten desigualdades socioeconómicas y en salud. Parte de la población de la comunidad donde se llevó a cabo el estudio no sigue las recomendaciones de la OMS para actividad física, en consecuencia, la falta de intervenciones en salud pública se pone en evidencia. Una mayor coherencia entre las resoluciones internacionales, las políticas públicas nacionales y su aplicación podría conducir a un aumento en los niveles de actividad física.(AU)
