ABSTRACT
RESUMEN Antecedentes: La cisticercosis es una infección parasitaria causada por la TaeniaSolium. Puede presentar una forma diseminada con compromiso sistémico. Clínicamente, la cisticercosis diseminada puede debutar con la presencia de nódulos subcutáneos. Presentamos un caso de diagnóstico de cisticercosis diseminada con la presencia de nódulos subcutáneos y síntomas respiratorios como única fuente de sospecha de enfermedad. Caso: Se presenta el caso de un paciente varón de 76 años de edad procedente de una región del Centro del Perú que acude a emergencia por hemoptisis, baja de peso y astenia de un año de evolución. Presentaba además nódulos subcutáneos no dolorosos, móviles en miembros superiores, inferiores, tórax, abdomen, cuello y cara. En la biopsia se demostró la presencia de cisticercocelullosae. Fue tratado con albendazol 400mg cada 12 horas por 6 meses, con evolución favorable. Conclusión: La cisticercosis es una enfermedad prevalente en nuestro país. Su presentación diseminada, sin embargo, no es tan frecuente. El diagnóstico puede ser difícil y a veces permanecer oculto, pues la clínica varía de silente a formas graves, dependiendo del órgano afectado, que en una forma diseminada pueden ser múltiples los órganos afectados, como el caso de nuestro paciente. Se concluye que las presencias de nódulos subcutáneos deben hacernos pensar en la posibilidad de formas diseminadas de cisticercosis.
ABSTRACT: Cysticercosis is a parasitic infection caused by Taenia Solium. It can be present as a disseminated form with systemic compromise. Disseminated cysticercosis may clinically debut with the presence of subcutaneous nodules. We present a case of diagnosis of disseminated cysticercosis with the presence of subcutaneous nodules and respiratory symptoms as the only source of suspected disease. Case: We present the case of a 76-year-old male patient from a region of central Peru who came to emergency due to hemoptysis, low weight and asthenia of one year of evolution. It also presented subcutaneous nodules that were painless, mobile in upper and lower limbs, abdomen, neck and face, the biopsy demonstrated with the presence of cysticercuscelullosae. He was treated with albendazole 400mg every 12h for 6 months, with favorable evolution. Conclusion: Cysticercosis is a prevalent disease in our country. Its disseminated presentation, however, is not as frequent. Diagnosis can be difficult and sometimes remain hidden, as the clinic varies from silent to severe, depending on the affected organ, which in a disseminated form can be multiple, as in the case of our patient. We conclude that the presence of subcutaneous nodules should make us think about the possibility of disseminated forms of cysticercosis.
ABSTRACT
Objective To construct and identify a recombinant Bifidobacteria(Bb) (pGEX-TSO45W-4B) vaccine of Taenia solium.Methods The TSO45W-4B gene of Taenia solium was synthesized.It was expected that the fragment length of the gene was 351 bp.The gene was cloned into Escherichia coli-Bifidobacteria(Bb) shutde vector pGEX-1λT to construct a recombinant plasmid pGEX-TSO45W-4B.The recombinant plasmid was electroporated into Bb to construct a recombinant Bb (pGEX-TSO45W-4B) vaccine.The vaccine was identified by restriction analysis,PCR and sequencing,which would demonstrate that the constructed recombinant Bb (pGEX-TSO45W-4B) vaccine of Taenia solium contained the gene of fragment length of 351 bp.Results The TSO45W-4B gene of 351 bp was synthesized.Restriction analysis,PCR and sequencing results showed that the recombinant Bb (pGEX-TSO45W-4B) vaccine of Taenia solium was successfully constructed and contained the gene fragment of 351 bp.Conclusion The recombinant Bb (pGEX-TSO45W-4B) vaccine of Taenia solium is successfully constructed,which lays a foundation for the study of expression and immunogenicity of the vaccine.
