ABSTRACT

La terapia de reemplazo enzimático disminuye la morbilidad y mejora la calidad de vida de los pacientes con mucopolisacaridosisii. Se han descrito reacciones de hipersensibilidad inmediata a este fármaco. La desensibilización es un tratamiento que induce la tolerancia temporaria a una droga y permite al paciente alérgico recibir la medicación.Se presenta el caso de un niño de 7 años con diagnóstico de síndrome de Hunter que, luego de 4 años de tratamiento con idursulfase, tuvo dos episodios de anafilaxia durante la infusión del fármaco. Se detectó inmunoglubulina E específica mediante pruebas cutáneas, y fue positiva la intradermorreacción con dilución 1/10 (0,2 mg/ml). Se realizó un protocolo de desensibilización de 12 pasos, sin presentar eventos adversos. La evaluación alergológica y la posibilidad de desensibilización constituyeron herramientas útiles en el manejo de nuestro paciente


Enzyme replacement therapy with idursulfase decreases morbidity and improves quality of life of patients with mucopolysaccharidosis ii. Immediate hypersensitivity reactions to this drug have been described. Desensitization is a treatment that induces temporary tolerance to a culprit drug, allowing the allergic patient to receive the medication.We present the case of a 7-year-old patient diagnosed with Hunter syndrome who presented, after 4 years of treatment, two episodes of anaphylaxis during the infusion of idursulfase. Detection of specific immunoglobulin E was carried out using skin tests, with intradermal reaction at a 1/10 dilution (0.2 mg/ml) being positive. A 12-step desensitization protocol was performed without presenting adverse events.The allergological evaluation and the possibility of desensitization were useful tools in the management of our patient.

ABSTRACT

Los anticuerpos monoclonales que inhiben los puntos de control PD-1 y CTLA-4 se usan actualmente en el tratamiento del melanoma y cáncer metastásico de pulmón de células no pequeñas, entre otros. Se refiere el caso de una paciente con cáncer de pulmón en tratamiento con pembrolizumab. La paciente se presentó con edema facial y parálisis facial periférica. En el laboratorio se observó la hormona tirotrofina (TSH) elevada y se llegó al diagnóstico de hipotiroidismo por pembrolizumab. Inició tratamiento con levotiroxina con mejoría clínica. Se presenta este caso por el importante papel del dermatólogo en el manejo multidisciplinario del paciente oncológico. (AU)


Monoclonal antibodies that inhibit PD-1 and CTLA-4 control points are currently used in the treatment of melanoma and metastatic non-small cell lung cancer, among others. The case of a patient, with lung cancer being treated with Pembrolizumab. The patient was presented with facial edema and peripheral facial paralysis and in the laboratory the elevated hormone Tyrotrophin (TSH) was observed, the diagnosis of pembrolizumab hypothyroidism was reached. She started treatment with levothyroxine with clinical improvement. This case is presented by the important role of the dermatologist in the multidisciplinary management of the cancer patient. (AU)
