ABSTRACT

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

ABSTRACT

Un tópico de análisis crítico es un resumen estandarizado que se organiza en torno a una pregunta clínica estructurada, realiza una revisión crítica y resalta la relevancia de sus resultados aplicados a nuestra realidad. El estudio analizado evalúa en 1100 pacientes de 12 años o más portadores de fibrosis quística (FQ) homocigotos para la mutación más frecuente phe508del CFTR, la terapia combinada de dos moduladores de la proteína CFTR, comparado con placebo, la que mostró mejoría significativa de la función pulmonar (VEF1) de 2.6 a 4 puntos porcentuales 1. Estos resultados proponen un tratamiento curativo al 50 por ciento de los pacientes en USA y al 15 por ciento en nuestro país, una vez superado los costos.


A CAT is a standardized summary of research evidence organized around a clinical question, aimed to provide a critique of the research and a statement of the clinical relevance of results. In the analyzed paper, the authors evaluated 1100 patients with cystic fibrosis (CF) 12 years and older with two copies of phe508del CFTR genetic mutation, the combination therapy of two CFTR modulators led to mean absolute improvements in lung function (VEF1) between 2.6 and 4 percentage points, which was statistically significant. These results are promising for the 50 percent of the USA CF population and 15 percent of the CF Chilean population.

ABSTRACT

El síndrome de nistagmo vertical hacia abajo (NVA) es una forma común de nistagmo de fijación adquirido que se presenta con nistagmo persistente con fase rápida en dirección descendente, mareo, oscilopsia y alteraciones de la marcha. Se considera un trastorno vestíbulo-cerebelar debido a un defecto en las células de Purkinje en el flóculo del cerebelo. Las causas reportadas con mayor frecuencia son los trastornos degenerativos cerebelares e isquemia cerebelar, sin embargo, en un gran porcentaje de los pacientes la etiología permanece incierta (forma idiopática). El NVA se puede dar en un contexto más amplio de neuropatía somatosensorial y ataxia cerebelar en el síndrome CANVAS. Las medidas terapéuticas incluyen evitar la posición supina y prona al descansar, rehabilitación vestibular y tratamiento farmacológico con aminopiridinas, entre otros. En este artículo presentamos dos casos de NVA así como la revisión de la literatura.


Downbeat nystagmus syndrome (DBN) is a frequent form of acquired fixation nystagmus, it presents with persisting nistagmus with fast phases directed downward, dizziness, oscillopsia and gait disturbances. It is considered a vestibulocerebellar disorder due to a bilateral defect of the Purkinje cells in the cerebellar flocculus. Most reported causes are degenerative disorders of the cerebellum and cerebellar ischemia, nevertheless the etiology remains unknown in a large percentage of patients (idiopathic form). DBN may present in a broader context of somatosensory neuropathy and cerebellar ataxia as in CANVAS syndrome. Therapeutic measures includes avoiding the supine and prone position when resting, vestibular rehabilitation, and pharmacologic treatment with aminopyridines, among others. In this article we present two cases of DBN and review of literature.

ABSTRACT

PURPOSE: Roflumilast is the only oral phosphodiesterase 4 inhibitor approved to treat chronic obstructive pulmonary disease (COPD) patients [post-bronchodilator forced expiratory volume in 1 second (FEV1) <50% predicted] with chronic bronchitis and a history of frequent exacerbations. This study evaluated the efficacy and safety of roflumilast in Korean patients with COPD and compared the efficacy based on the severity of airflow limitation. MATERIALS AND METHODS: A post-hoc subgroup analysis was performed in Korean COPD patients participating in JADE, a 12-week, double-blinded, placebo-controlled, parallel-group, phase III trial in Asia. The primary efficacy endpoint was the mean [least-squares mean adjusted for covariates (LSMean)] change in post-bronchodilator FEV1 from baseline to each post-randomization visit. Safety endpoints included adverse events (AEs) and changes in laboratory values, vital signs, and electrocardiograms. RESULTS: A total of 260 Korean COPD patients were recruited, of which 207 were randomized to roflumilast (n=102) or placebo (n=105) treatment. After 12 weeks, LSMean post-bronchodilator FEV1 increased by 43 mL for patients receiving roflumilast and decreased by 60 mL for those taking placebo. Adverse events were more common in the roflumilast group than in the placebo group; however, the types and frequency of AEs were comparable to those reported in previous studies. CONCLUSION: Roflumilast significantly improved lung function with a tolerable safety profile in Korean COPD patients irrespective of the severity of airflow limitation.

ABSTRACT

Respiratory complications are the first cause of death in patients with tetraplegia, including both the acute and chronic stage of the disease. They include a wide variety of respiratory problems, such as repeated pneumonias, atelectasis, unsatisfactory secretions manage, respiratory failure, hypoventilation, and other complex pathologies such as pulmonary embolism and sleep apnea syndrome. It has been postulated that the main cause of all these respiratory complications is weakness of inter costais and abdominal muscles, and partial or complete dysfunction of the diaphragm. Today we have multiple therapeutic alternatives to prevent, manage and specifically treat the multiple types of complications. The main objective of this article is to review the different therapeutical alternatives and encourage the study of this important topic.


Las complicaciones respiratorias son la principal causa de muerte en los pacientes con tetraplejia, tanto en el período agudo como crónico. En esta categoría se incluyen diversas alteraciones como neumonías recurrentes, atelectasias, mal manejo de las secreciones, insuficiencia respiratoria e hipoventilación. Además, son frecuentes patologías más complejas como el tromboembolismo pulmonar y la apnea obstructiva del sueño. Se postula que las causas principales de los problemas respiratorios son la debilidad de los músculos intercostales y abdominales, y la disfunción parcial o total del diafragma. Hoy en día existen múltiples alternativas terapéuticas para prevenir, manejar y tratar en forma específica las diversas complicaciones. El propósito de este artículo es revisar las opciones terapéuticas actualmente vigentes y despertar el interés entre los clínicos para profundizar más en este importante tema.

ABSTRACT

Se presentan los resultados obtenidos con la amrinoma (A), un cardiotónico no digitálico y sin efectos adrenérgicos, en la insuficiencia cardíaca grave (IC), refractaria (R) y/o con intolerancia (I) a otras drogas. En dosis de 300-600mg/día per os fue utilizada en 10 pacientes (p). Todos estaban en clase funcional (CF) IV (NYHA) y 2 p dependientes de medicación EV (nitroprusiato y/o dopamina). Cinco p tenían miocardiopatía dilatada, 2 valvulopatía aórtica, 1 cardiopatía coronaria y 2 valvulopatía mitral. Todos los p tenían cardiomegalia (Rx). Los valores medios de DDVI y FA, determinados por ecocardiogramas modo M, fueron de 7,36 + ou - 0.84 cm y 17,18 + ou - 7%, respectivamente; la FEVI media (por centellografía con Tc99m) era de 13,66 + ou - 3,16%. El seguimiento hasta el deceso o cierre del estudio osciló entre 3 y 12 meses (media 7,7 meses/p). Nueve p mostraron mejoría clínica y Rx ostensibles, pasando a CF grado II 2 p y grado III 7 p. El restante no cambió su CF. El análisis estadístico de las variaciones (bi o trimestrales) de DDVI, FA y FEVI no mostró diferencias significativas. Los efectos secundarios fueron leves (plaquetopenia transitoria, anorexia, náuseas) y no obligaron a suspender la A. Siete p fallecieron en forma brusca. Se concluye que en p con IV la A: 1) mejora la CF de manera sostenida; 2) no ocasiona efectos secundarios trascendentes, y 3) no parece aumentar la supervivencia de los p con IC en CF IV

ABSTRACT

Recientemente se ha descrito que la 5-amino 3,4'-bipiridin-6 (1H)-ONA, WIN 40680 ó amrinone, es un nuevo agente inotrópico positivo que parece ofrecer ventajas importantes sobre los glicósidos cardíacos. Se estudiaron los efectos de este agente en un preparado cardiopulmonar modificado que permite además del estudio controlado de la contractilidad cardíaca, la medición del flujo coronario y del consumo de oxígeno del corazón. En dos modelos de corazón insuficiente, la administración de 5 mg de amrinone produjo un marcado aumento del gasto cardíaco y una importante disminución de la presión de la aurícula izquierda, corrigiendo totalmente la insuficiencia. El agente produce además un aumento del 78% en el flujo coronario. En estas preparaciones, el amrinone produce un aumento proporcionalmente mayor en el gasto cardíaco que el que se observa en el consumo de oxígeno, por lo que el agente aumenta la eficiencia de estos corazones. Estos resultados sugieren que el nuevo compuesto podría ser de gran utilidad en el tratamiento de la insuficiencia cardíaca congestiva
