ABSTRACT
Presentamos el caso de un paciente varón de 48 años de edad, con diagnóstico de diabetes mellitus tipo 2, no controlada, de diez años de evolución, a quien se le diagnosticó tuberculosis pulmonar mediante signos clínicos, radiográficos y cultivo en esputo positivo para Mycobacterium tuberculosis, sensible a drogas antituberculosas de primera línea. Recibió isoniacida, rifampicina, etambutol y pirazinamida. Dos meses después de iniciado el tratamiento presentó hipersensibilidad a medicamentos, con los siguientes signos y síntomas: rash dérmico generalizado, prurito generalizado, anemia Coombs positiva, eosinofilia y síntomas sistémicos, compatibles con el síndrome DRESS (drug rash with eosinophilia and systemic symptoms). Ante ello, se suspendió la medicación antituberculosa y se instaló tratamiento con antihistamínicos y corticoides sistémicos, con remisión y mejoría de síntomas. Posteriormente, recibió un esquema individualizado de tratamiento para tuberculosis consistente en medicamentos mínimamente hemato-hepatotóxicos, similar al indicado en pacientes inmunosuprimidos. Desde entonces presenta baciloscopias negativas.
A case of a 48 year-old male with uncontrolled type 2 diabetes mellitus for the past ten years who presented pulmonary tuberculosis by clinical, radiographic signs and Mycobacterium tuberculosis sputum culture, sensitive to first line treatment drugs, is reported. He received standard treatment with isoniazid, rifampicin, ethambutol, pyrazinamide showing two months later drug hypersensitivity consisting in generalized skin rash, pruritus, positive Coombs anemia, eosinophilia and systemic symptoms compatible with DRESS syndrome (drug rash with eosinophilia and systemic symptoms). The antituberculous drugs were suspended and systemic antihistaminic drugs and corticoids were administered with remission and improvement of symptoms. Afterwards individualized treatment scheme for tuberculosis consisting in minimal hemato-hepatotoxic drugs similar to those indicated to immunosuppressed patients was indicated. Baciloscopies have been negative since.

A síndrome da eosinofilia-mialgia foi descrita em 1989 em pacientes que apresentavam mialgia progressiva e incapacitante e eosinofilia sérica, nos líquidos e secreções. A maioria dos pacientes relatava uso prévio de L-triptofano. Sintomas respiratórios são relatados em até 80 por cento dos casos, eventualmente como manifestação única. O tratamento inclui suspensão da droga e corticoterapia. Relatamos o caso de uma mulher de 61 anos com insuficiência respiratória aguda após uso de L-triptofano, hidroxitriptofano e outras drogas. A paciente apresentava eosinofilia no sangue, lavado broncoalveolar e derrame pleural. Após a suspensão da medicação e corticoterapia, houve melhora clínica e radiológica em poucos dias.
Eosinophilia-myalgia syndrome was described in 1989 in patients who presented progressive and incapacitating myalgia and eosinophilia in blood, fluids and secretions. Most patients report previous L-tryptophan intake. Respiratory manifestations are found in up to 80 percent of the cases, occasionally as the only manifestation. Treatment includes drug discontinuation and administration of corticosteroids. Here, we describe the case of a 61-year-old female admitted with acute respiratory failure after using L-tryptophan, hydroxytryptophan and other drugs. The patient presented eosinophilia, together with elevated eosinophil counts in the bronchoalveolar lavage and pleural effusion. After discontinuation of the drugs previously used, corticosteroids were administered, resulting in clinical and radiological improvement within just a few days.

Para la clasificación de la eosinofilia se tienen en cuenta varios parámetros, el más utilizado es el recuento de eosinófilos; la cual la clasifica en leve, moderada y severa, también se ha utilizado para la clasificación el mecanismo de producción, que la divide en clonal y no clonal y el grado de infiltración de tejidos, que la clasifica en tisular, medular y periférica; todas estas han sido realizadas de manera arbitraria. Teniendo en cuenta; las diferentes causas de clasificación, se encuentra la eosinofilia clonal, como una manifestación neoplásica derivada de las células madres CD34, y la eosinofilia no clonal como una manifestación reactiva inducida por mecanismos relacionados a las enfermedades con las cuales se encuentran asociadas; entre estas están, las enfermedades infecciosas; en este grupo sobresalen las infestaciones parasitarias como la causa más frecuente, las enfermedades alérgicas; en particular las reacciones de hipersensibilidad tipo I, las enfermedades inmunológicas no alérgicas; que son divididas en tres grupos; enfermedades autoinmunes órgano-específicas, órgano-inespecíficas y las inmunodeficiencias, encontramos también las asociadas a cáncer; de las cuales se hará mención a las más frecuentes, las alteraciones endocrinas y metabólicas; en donde la insuficiencia suprarrenal en pacientes infectados por el virus de la inmunodeficiencia humana es la que más reporte tiene, las de origen farmacológico y los trastornos idiopáticos; en el que entra el síndrome hipereosinofílico, como un conjunto de trastornos heterogéneos que se definen por un recuento de eosinófilos superior a 1.500 por mm3 por más de seis meses, con compromiso de órganos blancos y exclusión de otras posibles causas de eosinofilia y otros casos de eosinofilia más raros como la eosinofilia familiar y la eosinofilia idiopática adquirida. Es importante recordar que independiente de la causa y del nivel de eosinófilos, el paciente tiene el derecho al diagnóstico y tratamiento...

Eosinophilia-myalgia syndrome (EMS) has been linked to ingestion of tryptophan contaminated with 1,1'-ethylidene-bis[L-tryptophan] (EBT), but other contaminants have received little study. The authors identified 101 lots of L-tryptophan that had been consumed either by persons with EMS or by asymptomatic tryptophan users and quantified the amounts of EBT and five other contaminants in each lot. After stratification of case and noncase lots by time of manufacture to adjust for the strong sequential pattern over time among case and noncase lots, higher EBT levels were still associated with a lot's case status, but the association lacked statistical significance (p = 0.120, odds ratio = 1.56, 95% confidence interval 0.758-3.23). While these findings do not rule out the possibility that EBT is the etiologic agent in EMS, they raise the possibility that other chemical contaminants in manufactured tryptophan modify the effects of EBT or that the causal agent of EMS is an entirely distinct compound.

Ha habido importantes avances en el conocimiento del metabolismo del triptofano, la síntesis de serotonina y los receptores serotoninérgicos encefálicos. Se ha determinado la efectividad terapéutica del 5-hidroxitriptofano en la depresión, insomnio, dolor crónico, mioclonías, etc. Eso sí, ha surgido inquietud al establecerse, como efecto adverso del tratamiento con L-triptofano, la producción del síndrome de mialgia-eosinofilia con compromiso importante de las fuerzas debido a una polineuropatía
