RESUMO

Objetivos: Imatinib cambió el paradigma de la leucemia mieloide crónica (LMC), tras lograr en los ensayos clínicos frente a interferón mejor tasa de respuestas y supervivencia libre de progresión, con un aceptable perfil de toxicidad. El objetivo del presente estudio fue evaluar la efectividad, seguridad y adherencia de imatinib en LMC en la práctica clínica habitual.Métodos: Estudio observacional retrospectivo en pacientes con LMC en fase crónica tratados con imatinib. Objetivos principales: respuesta completa hematológica (RCH), respuesta completa citogenética (RCyC), respuesta mayor molecular (RMM), adherencia (ADH) y efectos adversos (EA). Las tasas de respuesta fueron definidas según criterios de The European LeukemiaNet y la ADH como dosis totales dispensadas x 100/dosis totales prescritas. Se consideraron adherentes aquellos pacientes con ADH ≥85%. Variables secundarias: supervivencia libre de progresión (SLP) y global (SG).Resultados: Se incluyeron un total de 39 pacientes. Tasas de respuesta: RCH 100%, RCyC 84,6% y RMM 66,7%. La ADH media al tratamiento fue de 94,9%, con un 92,3% de pacientes adherentes. Las tasas de SLP y SG estimadas a los 8 años fueron 94,4% (IC95%: 86,9-100,0) y 94,4% (IC95%: 87,3-100,0) respectivamente. EA no hematológicos más frecuentes: edemas (53,8%), dolor músculo-esquelético (43,6%) y calambres (38,5%). Se encontró neutropenia y trombocitopenia grado 3-4 en el 10,3% y 5,1% de los pacientes respectivamente.Conclusiones: Imatinib induce respuestas duraderas en una notable proporción de pacientes, consiguiendo mantener la enfermedad bajo control. Este estudio confirma el beneficio de imatinib en práctica clínica habitual. El perfil de seguridad es consistente con los resultados obtenidos en estudios previos. (AU)


Objectives: Imatinib changed the treatment paradigm of chronic myeloid leukemia (CML) after yielding better response rates and progression free survival than interferon-α, with an acceptable safety profile. The aim of this study was to evaluate the effectiveness, safety and adherence of imatinib in the treatment of CML in clinical practice.Methods: Retrospective study carried out in patients with CML in chronic phase treated with imatinib. Primary endpoints: complete hematological response (CHR), complete cytogenetic response (CCyR), major molecular response (MMR), treatment adherence (ADH) and adverse events (AE). Response rates were defined according to the criteria of The European LeukemiaNet and ADH was estimated as number of dosage units dispensed x 100/ number of dosage units prescribed. Patients were adherent if their ADH was ≥85%. Secondary endpoints: progression free survival (PFS) and overall survival (OS).Results: 39 patients were included. Response rates: CHR 100% (39/39); CCyR 84.6% (33/39); and MMR 66.7% (26/39). The mean ADH was 94.9% (59.0%-100%), with a 92.3% of patients considered adherents. PFS and OS rates estimated at 8 years were: 94.4% (95% CI: 86.9-100.0) and 94.4% (95% CI: 87.3-100.0), respectively. Most frequent non-hematological AE: edema 53.8% (21/39), musculoskeletal pain 43.6% (17/39) and muscle cramps 38.5% (15/39). Grade 3-4 neutropenia and thrombocytopenia were found in 10.3% (4/39) and 5.1% (2/39) of patients, respectively.Conclusions: Imatinib induced sustainable responses in a remarkable proportion of real world patients, managing to keep the disease under control. This study confirms the benefits of imatinib in clinical practice. The safety profile was consistent with earlier reports. (AU)

RESUMO

Pentachlorophenol (PCP) was, and still is, one of the most frequently used fungicides and pesticides. The use of PCP has been more restricted during the last few years. PCP's most important industrial application is as a wood preservative. The pentachlorophenol can be absorbed into the body by all the routes of occupational exposure. Some epidemiological observations suggest that exposure to PCP solutions may result in an increased risk for certain diseases in humans, e.g., immunodeficiency, blood disorders, malignancies, congenital anomalies. Chronic poisoning is difficult to detect since symptoms are often vague. Acute poisoning is due to interference with oxidative phosphorylation and can present itself as an unexpected case of sudden death. Four cases of PCP poisoning, including one fatalitie, occurred in two small wood preservative plants. All cases presented with increased serum creatinine phosphokinasa. The clinical finding are reported, and treatment modalities commented. At present there is no antidote for PCP. The basis for treatment is intensive supportive care to maintain vital bodily function. In one patient plasmapheresis was used and rapid recover was obtained. It is suggested that such therapy may be lifesaving in such intoxications.

RESUMO

El pentaclorofenol (PCP) era, y todavía es, uno de los fungicidas y pesticidas más usados. El empleo de PCP ha sido más restringido en los últimos años. La aplicación industrial más importante del PCP es como conservante de la madera. El pentaclorofenol puede ser absorbido por todas las rutas de exposición ocupacional. Algunas observaciones epidemiológicas sugieren que la exposición a soluciones de PCP puede incrementar el riesgo de algunas enfermedades (inmunodeficiencia, trastornos sanguíneos, tumores, anomalías congénitas, etc). La intoxicación crónica es difícil de detectar ya que los síntomas a menudo son vagos. La intoxicación aguda es debida a la interferencia de la fosforilación oxidativa y puede presentarse como muerte súbita inesperada. Cuatro casos de intoxicación por PCP, uno de ellos fatal, ocurrieron en dos empresas madereras. Todos los casos cursaron con CPK elevada. La base del tratamiento son las medidas de soporte para mantener las funciones vitales. En un paciente se usó la plasmaféresis y se obtuvo una rápida mejoría. Se sugiere que esta terapia puede salvar la vida en este tipo de intoxicación (AU)

RESUMO

We report a case of miliary tuberculosis following extracorporeal shock wave lithotripsy (ESWL*). The patient had right lower caliceal and left distal ureteral calculi on excretory urography. He was hospitalized 50 days after ESWL with fever, weight loss and night sweats. Liver function tests were abnormal and he had hypoxemia. A chest x-ray at hospitalization was normal but a miliary pattern developed 10 days later. Diagnosis was tuberculosis based on culture of sputum in a Löwenstein medium. Liver biopsy confirmed caseating epithelioid granulomas. Antituberculous treatment was successful. We conclude that renal tuberculosis associated with calcification must be ruled out before treatment with ESWL to avoid a possible hematogenous dissemination.
