ABSTRACT

The advances in cancer therapy have included the development of drugs that inhibit immune checkpoint ligands. Two types of immune checkpoint inhibitors, both antibodies that target CTLA-4 and PD-1, have been approved for its use in NSCLC and melanoma as first-line or second-line therapy. Sadly, not desirable consequences of immunotherapy are immune-related adverse events. immune-related hypophysitis is the most common endocrine adverse event after thyroid disfunction. The particularity of endocrine immune-related adverse events is their non-reversibility, with incidence and prevalence destined to increase in the coming years, particularly if this form of therapy is used in the future for earlier stages of cancer. Therefore, hypophysitis represents a challenge for the physician, sometimes occurring without specific symptomatology and which should be considered for clinical management. In this review, we describe the current data regarding the pathophysiology and management for immune-related hypophysitis.

ABSTRACT

Resumen Desde el descubrimiento de Helicobacter pylori como agente infeccioso patógeno en el ser humano se ha ligado con diferentes enfermedades gástricas en el ser humano (úlcera péptica, adenocarcinoma gástrico y linfoma MALT). En los últimos años se ha encontrado además su potencial relación etiológica con enfermedades extradigestivas, tales como la anemia por deficiencia de hierro y la púrpura trombocitopénica inmune. El entendimiento de los mecanismos de defensa del huésped así como los factores de virulencia y patogenicidad de la bacteria ha permitido establecer indicaciones en las que la erradicación mediante antibióticos brinda un beneficio clínico, principalmente para las enfermedades gástricas. Recientemente ha aparecido creciente evidencia del beneficio de esta terapia en otras condiciones digestivas y no digestivas e incluso se ha demostrado un potencial impacto con la estrategia de tamizaje y erradicación poblacional de la bacteria para enfermedades de alta morbimortalidad como el cáncer gástrico. El aumento de la utilización de terapia antimicrobiana ha ido de la mano de la emergencia de la resistencia a los antibióticos empleados, lo cual acarrea un problema de salud pública. Esta revisión temática pretende actualizar los conceptos biológicos y clínicos de la infección y demostrar que esta infección aun debe considerarse como emergente.


Abstract Since the discovery of Helicobacter pylori as a pathogenic infectious agent in humans, it has been linked to different gastric diseases in humans (peptic ulcer, gastric adenocarcinoma and MALT lymphoma). In recent years, its potential etiological relationship with extradigestive diseases has also been found, such as iron deficiency anemia and immune thrombocytopenic purpura. The understanding of the host defense mechanisms as well as the virulence and pathogenicity factors of the bacteria has allowed us to establish indications in which antibiotic eradication provides a clinical benefit, mainly for gastric diseases. Recently there has been growing evidence of the benefit of this therapy in other digestive and non-digestive conditions and has even shown a potential impact with the population's screening and eradication strategy of the bacteria for diseases of high morbidity and mortality such as gastric cancer. The increase in the use of antimicrobial therapy has gone hand in hand with the emergence of resistance to the antibiotics used, which leads to a public health problem. This thematic review aims to update the biological and clinical concepts of the infection and demonstrate that this infection should still be considered as emerging.
