DOI:RESUMEN Fundamentos: La pérdida ósea en pacientes osteoporóticos, conlleva riesgo de fracturas, dolor óseo vertebral y disminución de la calidad de vida. El objetivo de este trabajo fue analizar el efecto de la teriparatida (TPTD) en pacientes osteoporóticos y con dolor vertebral.
Métodos:Estudio observacional longitudinal prospectivo, entre abril de 2006 y febrero de 2014, en los 77 pacientes tratados con TPTD en la Unidad del Dolor del Hospital de Teruel. La duración del tratamiento fue de 18 o 24 meses. Se utilizó la Escala Visual Analógica (EVA) para la medición del dolor y el cuestionario europeo de calidad de vida (EuroQol-5D) para obtener la tarifa social (TS), antes y después el tratamiento. Se realizó un análisis descriptivo, de regresión lineal y logística.Resultados: Se observó una mejoría del dolor (80%) y de la calidad de vida (65 %). Se mejoró la EVA media (5,42 a 3,47 puntos) y el EuroQol-5D (0,36 a 0,58 puntos). La regresión indicó una mejora de la EVA en 0,441 puntos por cada punto de EVA inicial, y de la TS en 0,0528 puntos por cada 0,1 puntos de TS inicial. La probabilidad de mejorar la EVA en 3 puntos (OR=2,021), fue mayor que de mejorar 2 puntos (OR=1,695).
Conclusiones:La TPTD en pacientes osteoporóticos reduce el dolor óseo y mejora la calidad de vida. Su efecto es mayor en pacientes con peor estado de salud inicial, pudiendo ser utilizado como criterio para las decisiones terapéuticas y de gestión clínica.Palabras clave: Calidad de vida. Dolor de espalda. Osteoporosis. Teriparatido.
ABSTRACT Impact of Teriparatide on Quality of Life in Osteoporotic PatientsBackground: Lost bone in osteoporotic patients increases the risk of fractures and back pain, and decreases quality of life. The aim of this study was to analyse the effect of teriparatide (TPTD) in osteoporotic patients with vertebral pain.
Objectives: To evaluate the Health-Related Quality of Life of elderly patient using teriparatide (TPTD) MethOds: A prospective observational study from April 2006 to February 2014 was carried out with 77 patients in a district Spanish hospital. The Health-Related Quality of Life of Patients (HRQoL) was assessed using the European Quality of Life Questionnaire (EQ-5D) before and after the TPTD therapy.A descriptive and regression analysis was done for assessing the data. Results: Mean age of patients was 75, 3 years (standard deviation, SD = 7,1 years); 4,1% were male. HRQoL of patient treated with TPTD improved from 0.36 to 0.58 EQ-5D score. The mean VAS improved (from 5.42 to 3.47), OR (2.021 to 1.695). In 80% of the patients a reduction of pain was observed as well as a reduction of fracture. cOnclusiOns: TPTD improved the HRQoL of patients studied, this data obtained can be used for cost-utility ulterior analysis.
Osteoporosis is frequent in elderly people, causing bone fractures and lowering their quality of life. The costs incurred by these fractures constitute a problem for public health. Markov chains were used to carry out an incremental cost-utility analysis of the four main drugs used in Spain to treat osteoporosis (alendronate, risedronate, denosumab and teriparatide). We considered 14 clinical transition states, from starting osteoporotic treatment at the age of 50 until death or the age of 100. Cost-effectiveness was measured by quality adjusted life years (QALYs). The values used in the Markov model were obtained from the literature. Teriparatide is the cost-effective alternative in the treatment of osteoporosis in patients with fractures from the age of 50, establishing a payment threshold of 20,000 EUR/QALY. However, it is the most expensive therapy, not appearing cost-effective in cases that do not present fracture and in ages over 80 years with fracture. Alendronate and denosumab therapies are presented as cost-effective osteoporosis treatment alternatives depending on the age of onset and duration of treatment. From the perspective of cost-effectiveness, establishing a payment threshold of 20,000 EUR/QALY, teriparatide is the cost-effective alternative in patients with fracture from the age of 50 to 70 years old in Spain.
