Abstract
Introduction

Obesity and psoriasis are two closely related chronic diseases and share multiple comorbidities. The common etiopathogenic basis would be a low-grade chronic inflammation, with a cross talk between adipose tissue and the skin. Obesity in patients with psoriasis results in a worse prognosis of the lesions and reduces the effectiveness of treatment.

Objectives

To assess the mid-term effect of liraglutide 3mg on anthropometric and morphofunctional, biochemical, and dermatological parameters in patients with psoriasis and obesity.

Material and methods

48 patients were included (52.1%♀, age 48.7±11.8 years, BMI 37.9±5.6kg/m2, psoriasis duration 17.8±11.1 years). The severity of the lesions was evaluated with the PASI (Psoriasis Area Severity Index) and the VAS (pain visual analog scale), and DLQI (Dermatology Quality Index) and the Beck depression test (BDI). Also, biochemical and anthropometric determinations were performed baseline and after 6 months.

Results

There was a reduction in BMI (37.9±5.6 vs 35±4.9; p<0.001), waist circumference (111.6±7 vs 104.7±9.3cm; p=0.001) and preperitoneal fat (1.6±0.6 vs 1.2±0.6cm; p<0.0001). PASI (12±8.4 to 4.3±2.9; p<0.0001), VAS (4.4±1.9 vs 2.2±1.6; p=0.003), DLQI (11.9±6.2 vs 4.8±3.4; p<0.0001) and BDI (15.5±3.6 vs 7.6±2.5; p<0.0001) improved significantly. C-reactive protein (3.9±3.1 vs 1.8±3.2mg/L; p<0.0001), homocysteine (13±3.3 vs 9.6±2.5μmol/L; p<0.0001), and plasma cortisol (12.5±4 vs 8.9±3.7μg/dL; p=0.001). In multiple regression analysis, dermatological improvement was independent of weight loss.

Conclusions

Liraglutide exerts beneficial effects not only on BMI and visceral fat, but also reduces inflammatory parameters in patients with psoriasis and obesity, improving skin lesions and quality of life.

Resumen
Introducción

La obesidad y la psoriasis son 2 enfermedades crónicas íntimamente relacionadas y comparten múltiples comorbilidades. La base etiopatogénica común sería una inflamación crónica de bajo grado, con un cross talk entre el tejido adiposo y la piel. La obesidad en los pacientes con psoriasis condiciona un peor pronóstico de las lesiones y disminuye la eficacia del tratamiento.

Objetivos

Determinar el efecto de liraglutida 3mg sobre parámetros antropométricos y morfofuncionales, bioquímicos, dermatológicos en pacientes con psoriasis y obesidad.

Material y métodos

Se incluyó a 48 pacientes (52,1% mujeres, edad 48,7±11,8 años, IMC 37,8±5,6kg/m2, tiempo de evolución de la psoriasis 17,8±11 años). Se evaluaron la gravedad de las lesiones con el Psorisis Area Severity Index (PASI) y la escala visual analógica (EVA) de dolor, así como el Dermatology Quality Index (DLQI) y el test de depresión de Beck (BDI), y se realizaron determinaciones analíticas y antropométricas basales y tras 6 meses.

Resultados

Hubo una reducción del IMC (38,2±5 vs. 35±4,9; p<0,0001), perímetro de cintura (111,6±7 vs. 104,7±9,3cm; p=0,001) y grasa preperitoneal (1,6±0,6 vs. 1,1±0,6cm; p<0,0001). El PASI (12±8,4 vs. 4,3±2,9; p <0,0001), EVA (4,4±1,8 vs. 2,2±1,6; p=0,03), DLQI (12±6,2 vs. 4,8±3,4; p <0,0001) y BDI (15,5±3,6 vs. 7,7±2,5; p <0,0001) mejoraron significativamente. Disminuyeron la PCR (3,9±3,1 vs. 1,8±3,2mg/l; p <0,0001), homocisteína (12,9±3,3 vs. 9,6±2,5μmol/l; p <0,0001), y cortisol (12,5±4 vs. 8,9±3,7μg/dl; p=0,001). En la regresión múltiple la mejoría de las lesiones fue independiente de la pérdida de peso.

Conclusiones

Liraglutida ejerce efectos beneficiosos no solo en el IMC y la grasa visceral, sino que reduce los parámetros inflamatorios en los pacientes con psoriasis y obesidad, mejorando las lesiones de la piel y la calidad de vida.
