CAR Immunotherapy for the treatment of infectious diseases: a systematic review.

Immunotherapy treatments aim to modulate the host's immune response to either mitigate it in inflammatory/autoimmune disease or enhance it against infection or cancer. Among different immunotherapies reaching clinical application during the last years, chimeric antigen receptor (CAR) immunotherapy has emerged as an effective treatment for cancer where different CAR T cells have already been approved. Yet their use against infectious diseases is an area still relatively poorly explored, albeit with tremendous potential for research and clinical application. Infectious diseases represent a global health challenge, with the escalating threat of antimicrobial resistance underscoring the need for alternative therapeutic approaches. This review aims to systematically evaluate the current applications of CAR immunotherapy in infectious diseases and discuss its potential for future applications. Notably, CAR cell therapies, initially developed for cancer treatment, are gaining recognition as potential remedies for infectious diseases. The review sheds light on significant progress in CAR T cell therapy directed at viral and opportunistic fungal infections.

Lepra de presentación focal en un paciente con mononeuropatía cubital en Uruguay / Focal presentation leprosy in a patient with ulnar mononeuropathy in Uruguay

La lepra, o enfermedad de Hansen (EH), es una enfermedad infectocontagiosa crónica de evolución lenta, causada por el bacilo Mycobacterium Leprae. Resulta un problema de salud importante en áreas endémicas con un gran impacto en la calidad de vida de los pacientes. Actualmente, se presenta como una causa infrecuente de neuropatía en nuestra región, pero su sospecha diagnóstica y su tratamiento precoz repercute a nivel pronóstico y funcional. Nuestro objetivo es analizar un caso único de Enfermedad de Hansen en nuestro país, haciendo enfoque en la presentación clínica y el abordaje médico-quirúrgico. Se presenta un paciente con un cuadro de debilidad progresiva de mano izquierda y una lesión de piel cronificada a nivel de codo, cuyos hallazgos clínicos, neurofisiológicos e imagenológicos fueron concordantes con una lesión del nervio cubital por atrapamiento en el conducto epitrócleo-olecraneano. La anatomía patológica mostró un proceso granulomatoso crónico y la baciloscopia fue positiva para bacilos ácido-alcohol resistentes con coloración de Hansel positiva, haciéndose diagnóstico de mononeuropatía cubital secundaria a infección por M. Leprae. Dada la severidad del compromiso nervioso, se realiza cirugía de nervio periférico con epineurotomía y descompresión nerviosa. En el caso de nuestro paciente con neuropatía cubital secundaria a enfermedad de Hansen, la cirugía descompresiva fue exitosa en el alivio del dolor, mostrándose como una opción terapéutica de relevancia en este tipo de pacientes(AU)

Leprosy, or Hansen disease, is a cronic infectious-contagious illness of slow progression that is caused by the bacillus Mycobacterium Leprae. It continues to be a major health problem in endemic areas and has a great impact on the quality of life of patients who suffer from it. It is currently presented as an infrequent cause of neuropathy in our region, but its diagnostic suspicion and therefore its early treatment have repercussions at the prognostic and functional level. Our goal is to analyze a unique case of Hansen's disease in our country, focusing on the clinical presentation and the medical-surgical approach. We present a patient with progressive weakness of the left hand and a chronic skin lesion at the level of the elbow, whose clinical, neurophysiological and imaging findings were consistent with an ulnar nerve injury due to entrapment in the epitrochlear-olecranon canal. The pathology showed a chronic granulomatous process; then bacilloscopy was performed, which was positive for acid-fast bacilli with positive Hansel staining, making a diagnosis of ulnar mononeuropathy secondary to infection by M. Leprae. Given the severity of the nerve involvement, peripheral nerve surgery with epineurotomy and nerve decompression was performed.In the case of our patient with ulnar neuropathy secondary to Hansen's disease, decompressive surgery was successful in relieving pain, proving to be a relevant therapeutic option in this type of patient

Mucocele fronto-etmoidal gigante / Giant frontoethmoidal mucocele

Se presenta el caso de un paciente varón de 18 años, con un gran mucocele frontoetmoidal derecho, postoperado en dos oportunidades anteriores, que acudió a nuestro servicio por un empeoramiento de la diplopía. Al examen físico se visualizaba un desplazamiento del globo ocular hacia abajo y afuera. Se le realizó estudios de imágenes, una tomografía computarizada y una resonancia magnética nuclear que sugerían un mucocele frontoetmoidal derecho. Se le realizó una sinusotomía tipo Draf III para drenaje de la lesión, con mejoría de los síntomas.

We present the case of an 18-year-old male patient with a large right frontoethmoidal mucocele, postoperatively on two previous occasions, who came to our department due to worsening diplopia. Physical examination revealed a downward and outward displacement of the eyeball. Imaging studies, computed tomography, and magnetic resonance imaging were performed that suggested a right frontoethmoidal mucocele. A type Draf III sinusotomy was performed to drain the lesion, with improvement of the symptoms.
