Manifestaciones cutáneas de la enfermedad injerto versushuésped en una población pediátrica y de adultos jóvenes / Cutaneous manifestations of graft versus host disease in a population of pediatric and young adults patients

El trasplante de médula ósea es una terapia potencialmente curativa para múltiples enfermedades; el alogénico es el más indicado en leucemias. La enfermedad injerto versus huésped (EIVH) constituye la principal complicación del trasplante de médula ósea alogénico. Tanto en la EIVH aguda como crónica, la piel es el órgano más frecuentemente comprometido. El objetivo fue analizar las manifestaciones cutáneas de esta entidad. Trabajo retrospectivo y descriptivo, que incluyó a 59 pacientes trasplantados de edades entre 0 y 20 años. En 50 casos, se realizó trasplante de médula ósea alogénico. Veinticinco pacientes desarrollaron EIVH (17, la forma aguda, y 8, la forma crónica), y 24 tuvieron compromiso cutáneo. En concordancia con lo comunicado se encontró que las manifestaciones cutáneas fueron la manifestación clínica más común de EIVH. El hallazgo principal en EIVH aguda en nuestra serie fue el rash eritematoso maculopapular y, en EIVH crónica, las lesiones escleróticas símil morf

Bone marrow transplant is a potentially curative therapy for several diseases, and allogeneic bone marrow transplant is the most commonly indicated type for leukemias. Graft versus host disease (GVHD) is the main complication of allogeneic bone marrow transplant. In both acute and chronic GVHD, the skin is the most frequently involved organ. The objective of this study was to analyze cutaneous manifestations of this disease. Retrospective and descriptive study that included 59 transplanted patients aged 0 to 20 years. In 50 cases allogeneic bone marrow transplant was performed. Twenty-five patients developed GVHD (17 acute disease and 8 chronic disease) and 24 of them had cutaneous involvement. According to the literature, skin compromise was the commonest clinical manifestation of GVHD. Main finding in acute GVHD in our series was the erythematous maculopapular rash, while in chronic GVHD they were sclerotic lesions resembling morphe

Long-term treatment with oral propranolol reduces relapses of infantile hemangiomas.

Oral propranolol (OP) has been shown to be effective in the treatment of complicated infantile hemangiomas (IHs), but optimal treatment duration to avoid relapses after stopping OP treatment has not been established. The objective of this study was to compare the frequency of relapses in long-term OP treatment with that of short-term OP treatment. This was a retrospective cohort study of 30 patients with complicated IHs who received treatment with OP. Patients were divided into two groups: OP treatment of 8 months or less and OP treatment of longer than 8 months. OP was started at 1 mg/kg/day in three doses every 8 hours for 1 week and increased to 1.5 to 4 mg/kg/day afterward. Ultrasound was used to objectively measure the response to treatment. Clinical and ultrasound assessment showed a decrease in IH size and resolution of complications in all patients (n = 30). In the short-term group (n = 10), nine patients (90%) relapsed after stopping treatment. In the long-term group (n = 20), the duration of treatment was 12 months in all patients, and only 1 patient out of the 20 treated (5%) showed relapse 2 months after finishing the full treatment (odds ratio = 18, 95% confidence interval 2.6, 123, p < 0.001. Twelve months of treatment of IH with OP is associated with a significantly lower rate of relapse than with shorter treatment.
