ABSTRACT

BACKGROUND AND AIMS: Pirfenidone (PFD), an oral antifibrotic drug, has been authorized by the EMA and FDA for treatment of idiopathic pulmonary fibrosis. Few studies have addressed its use in advanced liver fibrosis (ALF). We evaluated a prolonged-release formulation (PR-PFD) plus standard of care on disease progression in ALF. METHODS: 281 ALF patients from 12 centers receiving PR-PFD (600 mg bid) were screened; 122 completed 1 year of treatment. Additionally, 74 patients received only standard of care regimen. Average age was 64 ± 12 years, 58% female. 43.5% had fatty liver disease (NAFLD), 22.5% viral hepatitis C (VHC), 17% autoimmune hepatitis (AIH), and 17% alcoholic liver disease (ALD). Baseline fibrosis was F4 in 74% and F3 in 26%. Antifibrotic effects were assessed by transient elastography (Fibroscan®) and Fibro Test® (FT); Cytokines and PFD plasma levels were tracked and quality of life evaluated. RESULTS: We found a significant reduction in fibrosis in 35% of PR-PFD patients and only in 4.1% in non PR-PFD patients. Child-Pugh score improved in 29.7%. Biochemical values remained stable; 40.6% and 43.3% decreased ALT or AST, respectively. TGFß1 (pg/mL) levels were lower in PFD-treated patients. PFD serum concentration (µg/mL) was higher (8.2 ± 1.7) in fibrosis regression profile (FRP) patients compared to fibrosis progression profile (FPP) patients (4.7 ± 0.3 µg/mL, p < 0.01). 12% reported transient burning or nausea and 7% photosensitivity. Quality of life (Euro-Qol scale) improved from 62 ± 5 to 84 ± 3 (p < 0.001) and from 32 ± 3 to 42 ± 2 (p < 0.008) (FACIT scale). CONCLUSIONS: PR-PFD is efficacious and safe in ALF and associated with promising antifibrotic effects. TRIAL REGISTRATION: Clinical trial number: NCT04099407.

ABSTRACT

Objetivo. Informar acerca de la factibilidad de realizar yeyunostomía por vía laparoscópica en animales de experimentación. Sede. Hospital de Especialidades de tercer nivel de atención. Diseño. Estudio experimental, descriptivo. Método. El procedimiento se realizó en 5 animales (cerdos) mediante la siguiente técnica: por vía laparsocópica se "ancla" el intestino con dos suturas de nylon monofilamento a 40 cm del ligamento de Treitz, después se punciona la cavidad abdominal en su cuadrante superior izquierdo con una aguja de Touhy, manipulada desde el exterior y, bajo visión laparoscópica, se punciona el intestino, entre las dos suturas que lo "anclan", sin introducir la aguja directamente en la luz intestinal, a continuación se construye un túnel subseroso de 5 cm de longitud y, finalmente, se termina el procedimiento introduciendo la aguja y se pasa la sonda de alimentación, se retira la guía de metal, se fija la sonda y se observa su permeabilidad. A los 8 días de realizado el procedimiento se evalúa, por laparoscopía, la permanecia y permeabilidad de la sonda, presencia de infección local, fijación del intestino y fugas o torsión del mismo. Resultados. La sonda permaneció en su sitio, permeable, no se observó infección local o regional, el intestino permaneció fijo al retirar la suturas y al hacer lo mismo con la sonda no se observó fuga de contenido intestinal, tampoco rotación intestinal ni oclusión. Conclusión. La yeyunostomía subserosa es técnicamente fácil, segura, rápida y factible en cerdos
