ABSTRACT

BACKGROUND@#There is limited information about thymosin α1 (Tα1) as adjuvant immunomodulatory therapy, either used alone or combined with other treatments, in patients with non-small cell lung cancer (NSCLC). This study aimed to evaluate the effect of adjuvant Tα1 treatment on long-term survival in margin-free (R0)-resected stage IA-IIIA NSCLC patients.@*METHODS@#A total of 5746 patients with pathologic stage IA-IIIA NSCLC who underwent R0 resection were included. The patients were divided into the Tα1 group and the control group according to whether they received Tα1 or not. A propensity score matching (PSM) analysis was performed to reduce bias, resulting in 1027 pairs of patients.@*RESULTS@#After PSM, the baseline clinicopathological characteristics were similar between the two groups. The 5-year disease-free survival (DFS) and overall survival (OS) rates were significantly higher in the Tα1 group compared with the control group. The multivariable analysis showed that Tα1 treatment was independently associated with an improved prognosis. A longer duration of Tα1 treatment was associated with improved OS and DFS. The subgroup analyses showed that Tα1 therapy could improve the DFS and/or OS in all subgroups of age, sex, Charlson Comorbidity Index (CCI), smoking status, and pathological tumor-node-metastasis (TNM) stage, especially for patients with non-squamous cell NSCLC and without targeted therapy.@*CONCLUSION@#Tα1 as adjuvant immunomodulatory therapy can significantly improve DFS and OS in patients with NSCLC after R0 resection, except for patients with squamous cell carcinoma and those receiving targeted therapy. The duration of Tα1 treatment is recommended to be >24 months.

ABSTRACT

OBJETIVO: Se sugiere no utilizar Timosina alfa-1 como terapia adyuvante en el tratamiento del câncer. TECNOLOGÍA EVALUADA: El sistema inmunitario juega un rol fundamental en las propias defensas del organismo contra las células cancerosas. El timo juega un papel central en esta situación y modifica los linfocitos T, una clase de linfocitos. Los estudios de péptidos tímicos hallaron numerosos efectos sobre el sistema inmunitario. Existen dos grupos de péptidos tímicos disponibles para el tratamiento, a saber: los extractos purificados de timo animal (mayormente de terneros) y los péptidos de timo producidos de forma sintética. Se cree que los extractos de timo purificados (pTE, por sus siglas en inglés) y los péptidos tímicos sintéticos (sTP, por sus siglas en inglés) mejoran el sistema inmunitario de los pacientes con cáncer para poder luchar contra el crecimiento de células tumorales y resistir las infecciones por la inmunodepresión inducida por la enfermedad y el tratamiento antineoplásico. METODOLOGÍA: Este estudio incluyó 26 ensayos (2736 pacientes). Veinte ensayos investigaron los Pte (timoestimulina o timosina fracción 5) y seis ensayos investigaron los sTP (timopentina o timosina α1). 4 estudios evaluaron el uso de Timosina alfa-1 en pacientes con cáncer Cheng 2004; Gish 2009; Maio 2010; Schulof 1985. Veintiún ensayos informaron los resultados de la SG, seis los de la SLE, 14 los de la RT, nueve los de los EA y diez los de seguridade de los pTE y los sTP. El agregado de pTE no produjo beneficios en la SG (CR 1,00; IC del 95%: 0,79 a 1,25); la SLE (CR 0,97; IC del 95%: 0,82 a 1,16); ni en la RT (CR 1,07; IC del 95%: 0,92 a 1,25). La heterogeneidad de estos resultados fue de moderada a alta. Para la timosina α1el CR agrupado de la SG fue de 1,21 (IC del 95%: 0,94 a 1,56; p = 0,14), con una baja heterogeneidad; y de 3,37 (IC del 95%: 0,66 a 17,30; p = 0,15) para la SLE, con heterogeneidad moderada. Los pTE redujeron el riesgo de complicaciones infecciosas graves (CR 0,54; IC del 95%: 0,38 a 0,78; p = 0,0008; I2 = 0%). El CR de la neutropenia grave en los pacientes tratados con timoestimulina fue de 0,55 (IC del 95%: 0,25 a 1,23; p = 0,15). La tolerabilidad de los pTE y los sTP fue adecuada. La mayoría de ensayos tenían al menos un riesgo de sesgo moderado. RECOMENDACIONES Y JUICIOS: En general, no se hallaron pruebas de que el agregado de pTE al tratamento antineoplásico reduzca el riesgo de mortalidad o la progresión de la enfermedad, ni que mejore la tasa de respuestas tumorales al tratamiento antineoplásico. Se sugiere no utilizar Timosina alfa-1 como terapia adyuvante en el tratamiento del câncer.

ABSTRACT

COVID-19 is known for its magical infectivity, fast transmission and high death toll based on the large number of infected people. From the perspective of the clinical manifestation, autopsy examination and pathophysiology, the essence of COVID-19 should be viewed as a sepsis induced by viral infection, and has the essential characteristics as sepsis induced by other pathogens. Therefore, in addition to etiological and supportive treatment, immunomodulatory therapy is also appropriate to severe COVID-19. Although there is still a lack of consensus on immunotherapy for sepsis so far, relatively rich experiences have been accumulated in the past decades, which will help us in the treatment of severe COVID-19. This article will elaborate immunotherapy of sepsis, though it may not be consistent.

ABSTRACT

ABSTRACT Objective: To observe the effect of thymosin alpha l (Tα1) on severe acute pancreatitis (SAP) in rats. Methods: Twenty-four adult male Sprague-Dawley rats were randomly divided into three groups (eight in each group): control group (Group A), SAP group (Group B) and Tα1 treatment group (Group C). Animal models of SAP were made by retrograde injection of 5% sodium taurocholate into the biliopancreatic duct. Rats in Group C were treated with Tα1 (6 mg/kg) via intraperitoneal administration prior to SAP modelling. Eight rats in each group were sacrificed at 12 hours, respectively, after modelling. The serum levels of amylase, tumour necrosis factor-α (TNF-α), interleukin-lβ (IL-lβ and interleukin-6 (IL-6) were detected in each group. The pathological scores of the tissue in the pancreas head were observed by light microscopy. Results: The levels of serum amylase of Group B were 6378 ± 538 U/L, which were significantly higher than those (4587 ± 478 U/L) of Group C (p < 0.05). The levels of serum TNF-α of Group B were 360.32 ± 28.67 pg/mL, which were higher than those (269.99 ± 26.11 pg/mL) of Group C (p < 0.05). The levels of serum IL-lβ of Group B were 435.93 ± 36.00 pg/mL, which were higher than those (312.42 ± 17.89 pg/mL) of Group C (p < 0.05). The levels of serum IL-6 of Group B were 433.90 ± 28.36 pg/mL, which were higher than those (289.98 ± 23.00 pg/mL) of Group C (p < 0.05). The pancreatic pathological scores of Group B were 13.34 ± 2.19, which were higher than those (6.39 ± 1.86) of Group C (p < 0.05). Conclusion: Thymosin alpha 1 could decrease proinflammatory cytokines and reduce pancreas injury and had a protective effect in rats with SAP. This provides a new strategy for the clinical treatment of SAP.


RESUMEN Objetivo: Observar el efecto de la timosina alfa l (Tα1) sobre la pancreatitis aguda grave (PAG) en ratas. Métodos: Veinticuatro ratas Sprague-Dawley adultas machos fueron divididas aleatoriamente en tres grupos (ocho en cada grupo): grupo de control (grupo A), grupo de PAG (grupo B) y grupo de tratamiento con Tα1 (grupo C). Los modelos animales de PAG fueron creados mediante inyección retrógrada de taurocolato de sodio al 5% en el conducto biliopancreático. Las ratas del grupo C se trataron con Tα1 (6 mg/kg) via administración intraperitoneal antes del modelado de PAG. Las ocho ratas en cada grupo fueron sacrificadas a las 12 horas, respectivamente, después del modelado. Los niveles séricos de amilasa, factor-α de necrosis tumoral (TNF-α), interleucina-β (Il-β) e interleucina-6 (IL-6) fueron detectados en cada grupo. Las puntuaciones patológicas del tejido en la cabeza del páncreas fueron observadas mediante microscopía de luz. Resultados: Los niveles de amilasa sérica del grupo B fueron 6378 ± 538 U/L, y resultaron significativamente más altos (p < 0.05) que los niveles 4587 ± 478 U/L del grupo C. Los niveles séricos de TNF-α del grupo B fueron 360.32 ± 28.67 pg/mL, y resultaron ser más altos (p < 0.05) que los 269.99 ± 26.11 pg/mL del grupo C. Los niveles séricos de Il-β del grupo B fueron 435.93 ± 36.00 pg/mL, y fueron más altos (p < 0.05) que los 312.42 ± 17.89 pg/mL) del grupo C. Los niveles de suero IL-6 del grupo B fueron 433.90 ± 28.36 pg/mL, y resultaron ser más altos (p < 0.05) que los 289.98 ± 23.00 pg/mL del grupo C. Las puntuaciones patológicas pancreáticas del grupo B fueron 13.34 ± 2.19, y resultaron ser más altas (p < 0.05) que las puntuaciones 6.39 ± 1.86 del grupo C. Conclusión: La timosina alfa pudo disminuir las citoquinas proinflamatorias y reducir la lesión del páncreas, y tuvo un efecto protector en las ratas con PAG. Esto ofrece una nueva estrategia para el tratamiento clínico de PAG.
