Slide Content

Alteraciones Endocrinológicas en Ciertas Enfermedades Infecciosas Daniel Mauricio Mora Gómez Residente Pediatría - PUJ

Las infecciones afectan a multiples órganos generalmente limitándose un solo aparato, llegando a tener manifestaciones secundarias afectando el sistema endocrinológico. INTRODUCCIÓN

Sistema Inmunitario / Endocrino IL-6 interleucina-6 IL-1β interleucina-1β TNF-α factor de necrosis tumoral α Alteración en la comunicación bidireccional secundario a las citoquinas liberadas CRH hormona liberadora de corticotropina ACTH corticotropina Cortisol DHEA dihidroepiandronstenediona Esta respuesta inmunoendocrina conduce a una migración y reacción de las células inmunes contra el patógeno causante.

Concientizar a los profesionales en la salud en cuanto a las posibles asociaciones que se presentan entre el sistema endocrino y las infecciones virales, bacterianas, micóticas o parasitarias, y no descartarlas como procesos paralelos, y así, permitir un acercamiento más holístico evitando retrasos y fallas en el diagnóstico. OBJETIVO

Tuberculosis

Presencia M. tuberculosis 25% de población Gran causa de mortalidad Tuberculosis Alteración Diseminación generalizada Alteración endocrina Clinicamente significativo es raro Cronicidad Liberación prolongada de corticoides + reducción de DHEA Cambios respuesta Th1 a Th2

Tuberculosis ↑ Hormona de crecimento (GH) ↑ Hormona estimulante de tiroides (TSH) T4 normal; ↓ T3 Hiporexia y alteraciones en la utilización de lípidos Alteración hipotálamo, glándulas: pituitaria, tiroides, paratiroides, pancreática, los testículos u ovarios, y/o adrenales Enf. Addison, diabetes insípida, tuberculosis tiroidea, absceso selar, disfunción hipofisaria, cerebro perdedor de sal, hiper/hipocalcemia, etc.

Candidiasis

Candidiasis Pueden diseminarse de manera multisistémica ( tiroides e hipófisis , glándulas suprarrenales, páncreas y gónadas) Ptes. inmunosuprimidos incluyendo ptes. c on diabetes mellitus (DM) y síndrome de Cushing (SC). Agentes Comunes Mucormicosis Candidiasis Dermatofitosis

Deficiencia Th12 Defensa especifica contra C. albicans Candidiasis Candidiasis mucocutanea Manifestación más temprana Triada C andidiasis, hipoparatiroidismo crónico y la EA Poliendocrinopatía autoinmune - candidiasis - distrofia ectodérmica (APECED)

Candidiasis Disfunción Sexual masculina y reproductiva femenina Esteroides Inhibe síntesis de esteroidogénesis Suprarrenal Pseudohiperaldosteronismo, insuf. Suprarrenal, SIADH Glucocorticoides Altera sintesis y degradación MANEJO AZOLES

Toxoplasmosis

Toxoplasmosis Toxoplasmosis Testosterona ↑ Cambios comportamentales Conducta antisocial, agresividad y dominancia Inmunosupresión celular C aracterísticas > masculinas M ayor probabilidad de dar a luz a varones

Hay estudios que intentan relacionar el rol de la testosterona, progesterona, prolactina y el 17β-estradiol durante el embarazo en la regulación de la infección por T. gondii , se ha encontrado que existen factores hormonales protectores en modelos animales, hacen falta estudios en humanos. Toxoplasmosis

Hepatitis C

E nfermedad viral causada por el virus de hepatitis C (VHC). Poca conciencia de su diagnóstico, y baja tasa de manejo. Poco porcentaje es población pediátrica, aprox. 11 millones de pacientes <15 años con infección crónica por HC a nivel mundial Hepatitis C Trastornos Tiroideos I ncluye hipo/hipertiroidismo, tiroiditis de Hashimoto, o presencia de Ac antitiroideos asintomáticos Diabetes Mellitus tipo 2

Hepatitis C Factores de riesgo para aumento de Ac Tiroideos Predisposición genética Ingesta de yodo Deficit de selenio Exposición a dosis bajas de radiación Otras infecciones virales Infección crónica de Hepatitis C Ca papilar tiroideo

Hepatitis C Infección crónica de Hepatitis C DM tipo II ? Resistencia insulínica periférica Predisposición genética

A lteraciones de la GH, deficiencias de vitamina D, disfunción sexual. Hacen falta estudios para determinar las interacciones causales. Sigue sin existir una evidencia fuerte de que el virus llegue a alterar el eje hipotálamo-hipofisario. El IFN como manejo se ha asociado también a trastornos tiroideos. Hepatitis C

Virus y Endocrinología CMV, VZV, VIH Alteraciones hipotalámicas HSV ½, VIH, virus Hanta, SARS-CoV-2 y rubeola Hipofisitis Virus Hanta, VZV Hemorragia pituitaria HSV-1, VEB SIADH Virus Hanta, CMV, HSV, Coxsackie B1 Diabetes insípida

Fiebre Tifoidea

Fiebre Tifoidea Causada por S. typhi alta mortalidad en especial en la población pediátrica OmpA S. typhi SPI-18 Hemolisina

Malaria

I nfección parasitaria causada por el parásito Plasmodium falciparum o vivax. Tiene una presencia importante alrededor del mundo. Colombia es uno de los países con mayor prevalencia en las américas Malaria

Malaria ↑ Glucosa ↓ Citoquinas Tolerancia a enfermedad

Malaría Malaria Hiponatremia Diabetes insipida Hipercortisolemia Insuficiencia adrenal Hipotiroidismo Hiperglicemia Hipoglicemia SIADH

Conclusiones

Conclusiones E l proceso inflamatorio 2rio a la infección genera multiples alteraciones del aparato endocrino. Cualquier tipo de germen puede alterar diferentes ejes. Algunos patógenos alteran más una glándula de manera específica . La tiroides aparenta ser la glándula más afectada por las infecciones. Las hormonas pueden cambiar configuraciones dentro del patógeno . La fisiopatología de cómo la infección altera a las hormonas sigue requiriendo más estudio.
