Vasculitis reumatoidea: una manifestación poco habitual. Presentación de tres casos clínicos y revisión de la literatura

La vasculitis reumatoidea es una complicación sistémica y poco frecuente de la Artritis Reumatoidea. Si bien su incidencia ha descendido en los últimos años con el advenimiento de las nuevas terapias inmunosupresoras y biológicas, continua teniendo una alta morbimortalidad. Predomina en el sexo masculino, en pacientes seropositivos y con un largo período de la enfermedad establecida. Requiere de alta presunción diagnostica, siendo el compromiso cutáneo y nervioso periférico el más frecuente. La biopsia de nervio o piel es requerida habitualmente para su diagnóstico. El tratamiento se basa en corticoides e inmunosupresores. Presentamos tres casos clínicos y realizamos una revisión de la literatura.

Rheumatoid vasculitis is a rare systemic complication of rheumatoid arthritis. Although its incidence has decreased in recent years with the advent of new immunosuppressive and biological therapies, it continues to have a high morbidity and mortality. It predominates in males, in seropositive patients and with a long period of established disease. It requires high diagnostic presumption, with skin and peripheral nervous involvement being the most affected. Nerve or skin biopsy is usually required for diagnosis. Treatment is based on corticosteroids and immunosuppressants. We present three clinical cases and carry out a review of the literature.

EFFICACY AND SAFETY OF BIOLOGICAL TREATMENT FOR INFLAMMATORY BOWEL DISEASE IN ELDERLY PATIENTS: RESULTS FROM A GETECCU COHORT.

INTRODUCTION: Biological therapies used for the treatment of inflammatory bowel disease (IBD) have shown to be effective and safe, although these results were obtained from studies involving mostly a young population, who are generally included in clinical trials. The aim of our study was to determine the efficacy and safety of the different biological treatments in the elderly population. METHODS: Multicenter study was carried out in the GETECCU group.Patients diagnosed with IBD and aged over 65 years at the time of initiating biological therapy (infliximab, adalimumab, golimumab, ustekinumab or vedolizumab) were retrospectively included. Among the patients included, clinical response was assessed after drug induction (12 weeks of treatment) and at 52 weeks. Patients' colonoscopy data in week 52 were assesment, where available. Regarding complications, development of oncological events during follow-up and infectious processes occurring during biological treatment were collected (excluding bowel infection by cytomegalovirus). RESULTS: A total of 1090 patients were included. After induction, at approximately 12-14 weeks of treatment, 419 patients (39.6%) were in clinical remission, 502 patients (47.4%) had responded without remission and 137 patients (12.9%) had no response. At 52 weeks of treatment 442 patients (57.1%) had achieved clinical remission, 249 patients had responded without remission (32.2%) and 53 patients had no response to the treatment (6.8%). Before 52 weeks, 129 patients (14.8%) had discontinued treatment due to inefficacy, this being significantly higher (p<0.0001) for Golimumab - 9 patients (37.5%) - compared to the other biological treatments analysed. With respect to tumor development, an oncological event was observed in 74 patients (6.9%): 30 patients (8%) on infliximab, 23 (7.14%) on adalimumab, 3 (11.1%) on golimumab, 10 (6.4%) on ustekinumab, and 8 (3.8%) on vedolizumab. The incidence was significantly lower (p = 0.04) for the vedolizumab group compared to other treatments.As regards infections, these occurred in 160 patients during treatment (14.9%), with no differences between the different biologicals used (p = 0.61): 61 patients (19.4%) on infliximab, 39 (12.5%) on adalimumab, 5 (17.8%) on golimumab, 22 (14.1%) on ustekinumab, and 34 (16.5%) on vedolizumab. CONCLUSIONS: Biological drug therapies have response rates in elderly patients similar to those described in the general population, Golimumab was the drug that was discontinued most frequently due to inefficacy.

Effectiveness and safety of neoadjuvant therapy in triple-negative breast cancer in a real-world population.

OBJECTIVE: Triple-negative breast cancer is a subtype of aggressive breast cancer. Our aim is to evaluate the effectiveness and safety of neoadjuvant treatment in early-stage triple-negative breast cancer and to identify predictors of pathological complete response. METHODS: This is a single-center, retrospective study involving 79 patients with triple-negative breast cancer who initiated neoadjuvant treatment between January 2017 and October 2022. Descriptive analyses were performed as appropriate. Statistical analysis utilized bivariate logistic regression to explore the presence of factors related to pathological complete response, and the Kaplan-Meier method was employed for survival analysis. RESULTS: In the overall population, 27 patients (n=78; 34.6%) achieved pathological complete response in the breast and axillary lymph nodes, and 31 (n=73; 42.5%) achieved a grade 5 pathological complete response in the breast, according to the Miller and Payne classification. The addition of platinum to standard therapy improved both breast and axillary lymph node pathological complete response rates. Age less than 40 years was identified as a predictor of pathological complete response in our study population through bivariate analysis, while Ki67 levels lower than 70% were associated with a lower pathological complete response rate. Adverse events were reported in 72 patients (91.1%), with grade 3-5 adverse events observed in 33 (41.8%). There was a particularly notable increase in gastrointestinal and hematological adverse events when platinum was added. CONCLUSIONS: In this population, we observed moderate rates of pathological complete response with acceptable chemotherapy tolerance. Platinum-based chemotherapy appears to enhance the likelihood of achieving pathological complete response, albeit with a less favorable safety profile. Therefore, evaluating the benefit-risk balance is crucial when selecting the optimal chemotherapy regimen for individual patients.

Diagnosis and treatment of deep vein thrombosis of the lower and upper limbs. 2024 recommendations of the venous thromboembolism group of the Spanish Society of Internal Medicine.

Deep vein thrombosis (DVT) of the limbs is a common disease and causes significant morbidity and mortality. It is frequently the prelude to pulmonary embolism (PE), it can recur in 30% of patients and in 25-40% of cases they can develop post-thrombotic syndrome (PTS), with a significant impact in functional status and quality of life. This document contains the recommendations on the diagnosis and treatment of acute DVT from the Thromboembolic Disease group of the Spanish Society of Internal Medicine (SEMI). PE and thrombosis of unusual venous territories (cerebral, renal, mesenteric, superficial, etc.) are outside its scope, as well as thrombosis associated with catheter and thrombosis associated with cancer, which due to their peculiarities will be the subject of other positioning documents of the Thromboembolic Disease group of the Spanish Society of Internal Medicine (SEMI).

Multidisciplinary consensus document on the current treatment of bacille Calmette-Guérin-unresponsive non-muscle invasive bladder tumor.

Radical cystectomy is the current treatment of choice for patients with BCG-unresponsive non-muscle invasive bladder tumor (NMIBC). However, the high comorbidity of this surgery and its effects on the quality of life of patients require the investigation and implementation of bladder-sparing treatment options. These must be evaluated individually by the uro-oncology committee based on the characteristics of the BCG failure, type of tumor, patient preferences and treatment options available in each center. Based on FDA-required oncologic outcomes (6-month complete response rate for CIS: 50%; duration of response in responders for CIS and papillary: 30% at 12 months and 25% at 18 months), there is not currently a strong preference for one treatment over another, although the intravesical route seems to offer less toxicity. This work summarizes the evidence on the management of BCG-unresponsive NMIBC based on current scientific evidence and provides consensus recommendations on the most appropriate treatment.

Actuales retos diagnósticos genómicos en los Síndromes Hemofagocíticos en pediatría: reporte de caso

Introducción: La linfohistiocitosis hemofagocítica familiar (FHL) es una enfermedad del sistema autoinmune que se presenta con un síndrome inflamatorio excesivo causado por linfocitos T activados e histiocitosis. Cursa con herencia autosómica recesiva ligada al cromosoma X. Aproximadamente el 90% de los niños diagnosticados son menores de 2 años y la incidencia es de aproximadamente 0.12 por 100.000. Se puede dividir en cinco subtipos según la variante genética causante. Las variantes patogénicas más involucradas son en los genes de la perforina 1 (PRF1) y homólogo D de la proteína UNC-13 (UNC13D). Caso clínico: Se presenta el caso de un preadolescente de 11 años, con antecedente de infecciones recurrentes, quien cursa con síndrome convulsivo asociado a fiebre, peso y talla bajas para la edad, hepatomegalia y discapacidad cognitiva. En el abordaje inicial se descartan enfermedades infecciosas, inmunológicas, hematológicas, metabólicas y oncológicas. El exoma clínico para inmunodeficiencias primarias muestra una variante patogénica p.A91V homocigota en el gen de la PRF1 de herencia autosómica recesiva, resultado relacionado con linfohistiocitosis hemofagocítica familiar tipo 2 (FHL2). Discusión y conclusión: El cambio conformacional del PRF1 alterado reduce la actividad citotóxica de la proteína y provoca la enfermedad. Los pacientes portadores de defectos en el gen PRF1 son vulnerables a infecciones, enfermedades autoinmunes y tumores malignos. Con un diagnóstico definido y preciso es posible orientar las acciones en salud, pautas de seguimiento, evaluación de riesgo de heredabilidad a través de un caso índice para así encontrar otros posibles portadores, realizar un asesoramiento genético completo, implementar e iniciar tratamientos dirigidos que aminoren la morbilidad y mortalidad asociada a esta patología. Actualmente se cuenta con varios estudios en diferentes fases de investigación sobre moléculas que pueden intervenir en la historia natural de la enfermedad. (provisto por Infomedic International)

Introduction: Familial hemophagocytic lymphohistiocytosis (FHL) is a disease of the autoimmune system that presents with an excessive inflammatory syndrome caused by activated T lymphocytes and histiocytosis. It occurs with autosomal recessive inheritance linked to the chromosome X. Approximately 90% of diagnosed children are under 2 years of age and the incidence is approximately 0.12 per 100,000. It can be divided into five subtypes depending on the causative genetic variant. The most involved pathogenic variants are in the perforin 1 (PRF1) and UNC-13 protein homolog D (UNC13D) genes. Clinical case: The case of an 11-year-old preadolescent is presented, with a history of recurrent infections, who presents with convulsive syndrome associated with fever, low weight and height for age, hepatomegaly and cognitive disability. In the initial approach, infectious, immunological, hematological, metabolic and oncological diseases are ruled out. The clinical exome for primary immunodeficiencies shows a homozygous pathogenic variant p.A91V in the PRF1 gene of autosomal recessive inheritance, a result related to familial hemophagocytic lymphohistiocytosis type 2 (FHL2). Discussion and conclusion: The altered PRF1 conformational change reduces the cytotoxic activity of the protein and causes disease. Patients carrying defects in the PRF1 gene are vulnerable to infections, autoimmune diseases and malignant tumors. With a defined and precise diagnosis, it is possible to guide health actions, follow-up guidelines, evaluation of heritability risk through an index case in order to find other possible carriers, carry out complete genetic counseling, implement and initiate targeted treatments that reduce the morbidity and mortality associated with this pathology. Currently, there are several studies in different phases of research on molecules that may intervene in the natural history of the disease. (provided by Infomedic International)

Untreated combined persistent fetal vasculature with "coralliform" cataract in a Hispanic 21 year-old male.

Persistent fetal vasculature is a spectrum of ocular abnormalities linked to an incomplete regression of the fetal ocular vasculature. A 21-years old male patient came to the outpatient clinic reporting low vision and strabismus in his left eye since 3 years of age. Ophtalmological examination revealed a normal right eye, while the left eye had a best corrected visual acuity of hand-motion perception, a 30 prism diopters esotropia, a "coralliform" cataract and a vitreous stalk joining the posterior face of the lens and the optic nerve. The coralliform cataract possessed spindle-shaped processes radiating out of its center in an axial direction and was located in the posterior subcapsular area. The patient elected to not undergo vitreoretinal surgery due to the poor visual prognosis. The unusual cataract present in the described patient could be related to his untreated status, as previous authors have reported that untreated cataracts in persistent fetal vasculature may undergo diverse degenerations.

Immune-mediated hepatitis: Basic concepts and treatment.

Immunotherapy with immune checkpoint inhibitors (ICIs) has revolutionized advanced cancer management. Nevertheless, the generalized use of these medications has led to an increase in the incidence of adverse immune-mediated events and the liver is one of the most frequently affected organs. Liver involvement associated with the administration of immunotherapy is known as immune-mediated hepatitis (IMH), whose incidence and clinical characteristics have been described by different authors. It often presents as mild elevations of amino transferase levels, seen in routine blood tests, that spontaneously return to normal, but it can also manifest as severe transaminitis, possibly leading to the permanent discontinuation of treatment. The aim of the following review was to describe the most up-to-date concepts regarding the epidemiology, diagnosis, risk factors, and progression of IMH, as well as its incidence in different types of common cancers, including hepatocellular carcinoma. Treatment recommendations according to the most current guidelines are also provided.

Aplicación de un modelo farmacocinético poblacional para el seguimiento de pacientes en tratamiento con dolutegravir: estudio piloto

Introducción: a pesar de los avances en tratamiento antirretroviral, existe la posibilidad de que personas que viven con el virus de la inmunodeficiencia humana (VIH) experimenten falla terapéutica vinculada a múltiples factores que impactan en la respuesta al fármaco. Objetivos: evaluar la utilidad de aplicar un modelo farmacocinético en pacientes con diagnóstico de VIH en tratamiento con dolutegravir para el análisis de las concentraciones plasmáticas experimentales. Adicionalmente, se pretende identificar potenciales interacciones farmacológicas, evaluar adherencia y fallo terapéutico. Material y método: se realizó un estudio piloto transversal y observacional en pacientes VIH tratados con dolutegravir que incluyó la dosificación de la concentración plasmática, evaluación de adherencia mediante el cuestionario simplificado de adherencia a la medicación (SMAQ) y retiro de medicación. Se utilizó un modelo poblacional referenciado en la bibliografía para la predicción de concentraciones de dolutegravir en cada paciente y se compararon con las concentraciones experimentales. Resultados: fueron incluidos en el estudio 21 pacientes. Al cotejar las concentraciones plasmáticas experimentales con la simulación farmacocinética se encontraron diferencias para 12 pacientes, las cuales se explican por posibles interacciones farmacológicas, mala adherencia u otros factores que afectan la farmacocinética. Se detectó 38% de no adherencia de acuerdo con SMAQ y 23% de acuerdo con el retiro de medicación. Conclusiones: se expone el rol potencial de los modelos farmacocinéticos para la interpretación de concentraciones plasmáticas y se genera la necesidad de avanzar en este tipo de estudios para el establecimiento de rango terapéutico y aplicabilidad clínica.

Introduction: Despite advances in antiretroviral treatment, there is a possibility that people living with HIV may experience treatment failure linked to multiple factors that impact drug response. Objective: To evaluate the usefulness of applying a pharmacokinetic model in patients diagnosed with HIV undergoing treatment with dolutegravir for the analysis of experimental plasma concentrations. Additionally, the aim is to identify potential drug interactions, assess adherence, and therapeutic failure. Method: A cross-sectional, observational pilot study was conducted in HIV patients treated with dolutegravir, which included plasma concentration dosing, assessment of adherence using the Simplified Medication Adherence Questionnaire (SMAQ), and medication withdrawal. A population-based model referenced in the literature was used to predict dolutegravir concentrations in each patient and these were compared with experimental concentrations. Results: Twenty-one patients were included in the study. When comparing experimental plasma concentrations with pharmacokinetic simulation, differences were found for 12 patients, which can be explained by possible drug interactions, poor adherence, or other factors affecting pharmacokinetics. Non-adherence was detected in 38% according to the SMAQ and 23% according to medication withdrawal. Conclusions: The potential role of pharmacokinetic models in the interpretation of plasma concentrations is highlighted, emphasizing the need to advance in this type of studies to establish therapeutic ranges and clinical applicability.

Introducción: la colocación de prótesis metálicas autoexpansibles (PAE) por vía endoscópica surge como opción terapéutica para la obstrucción colónica neoplásica en dos situaciones: como tratamiento paliativo y como puente a la cirugía curativa. Este procedimiento evita cirugías en dos tiempos y disminuye la probabilidad de colostomía definitiva y sus complicaciones con el consecuente deterioro de la calidad de vida. Objetivo: comunicar nuestra experiencia en la colocación de PAE para el tratamiento paliativo de la obstrucción colorrectal neoplásica. Diseño: retrospectivo, longitudinal, descriptivo y observacional. Material y métodos: se incluyeron todos los pacientes a quienes el mismo grupo de endoscopistas les colocó PAE con intención paliativa por cáncer colorrectal avanzado entre agosto de 2008 y diciembre de 2019. Fueron analizadas las variables demográficas y clínicas, el éxito técnico y clínico, las complicaciones tempranas y tardías y la supervivencia. Resultados: se colocó PAE en 54 pacientes. La media de edad fue 71 años. El 85% de las lesiones se localizó en el colon izquierdo. En el 57% de los pacientes se realizó en forma ambulatoria. El éxito técnico y clínico fue del 92 y 90%, respectivamente y la supervivencia media de 209 días. La tasa de complicaciones fue del 29,6%, incluyendo un 14,8% de obstrucción y un 5,6% de migración. La mortalidad tardía atribuible al procedimiento fue del 5,6%, ocasionada por 3 perforaciones tardías: 2 abiertas y 1 microperforación con formación de absceso localizado. Conclusiones: la colocación de PAE como tratamiento paliativo de la obstrucción neoplásica colónica es factible, eficaz y segura. Permitió el manejo ambulatorio o con internación breve y la realimentación temprana, mejorando las condiciones para afrontar un eventual tratamiento quimioterápico paliativo. Las mayoría de las complicaciones fueron tardías y resueltas endoscópicamente en forma ambulatoria. (AU)

Introduction: endoscopic placement of self-expanding metal stents (SEMS) emerges as a therapeutic option for neoplastic obstruction of the colon in two situations: as palliative treatment and as a bridge to curative surgery. This procedure avoids two-stage surgeries and reduces the probability of permanent colostomy and its complications with the consequent deterioration in quality of life. Objective: to report our experience in the placement of SEMS as palliative treatment in neoplastic colorectal obstruction. Design: retrospective, longitudinal, descriptive and observational study. Methods: all patients in whom the same group of endoscopists performed SEMS placement with palliative intent for advanced colorectal cancer between August 2008 and December 2019 were analyzed. Data collected were demographic and clinical variables, technical and clinical success, early and late complications, and survival. Results: SEMS were placed in 54 patients. The average age was 71 years. Eighty-five percent were left-sided tumors. In 57% of the patients the procedure was performed on an outpatient basis. Technical and clinical success was 92 and 90%, respectively, and median survival was 209 days. The complication rate was 29.6%, including 14.8% obstruction and 5.6% migration. Late mortality attributable to the procedure was 5.6%, caused by 3 late perforations: 2 open and 1 microperforation with localized abscess formation. Conclusions: The placement of SEMS as a palliative treatment for neoplastic colonic obstruction is feasible, effective and safe. It allowed outpa-tient management or brief hospitalization and early refeeding, improving the conditions to face an eventual palliative chemotherapy treatment. Most complications were late and resolved endoscopically on an outpatient basis. (AU)

Divertículo de Meckel complicado. Experiencia de 15 años en un hospital interzonal / Complicated Meckel's diverticulum. Fifteen years of experiencein an interzonal hospital in the Province of Buenos Aires

Introducción: el divertículo de Meckel es la anomalía congénita más frecuente del tracto gastrointestinal. Puede presentarse con hemorragia, obstrucción intestinal o diverticulitis, complicaciones que disminuyen con la edad, por lo que en el adulto el diagnóstico suele ser incidental. El tratamiento de las complicaciones es quirúrgico, mediante diverticulectomía o resección segmentaria del intestino delgado, dependiendo de sus características morfológicas. Objetivo: analizar nuestra experiencia en el manejo del divertículo de Meckel complicado en un período de 15 años. Diseño: estudio descriptivo, observacional, transversal, retrospectivo. Material y métodos: se revisaron las historias clínicas de los pacientes operados por divertículo de Meckel complicado en el Servicio de Cirugía General del Hospital San Roque durante el periodo 2007-2022. Se registraron datos demográficos, presentación clínica, diagnóstico preoperatorio, tratamiento quirúrgico, complicaciones postoperatorias y hallazgos histopatológicos. Resultados: se incluyeron 25 pacientes, 21 (84%) hombres, 3 menores de 18 años. La presentación clínica fue un síndrome de fosa iliaca derecha en el 80% de los casos, obstrucción intestinal en el 16% y hemorragia en el 4%. En solo 2 casos se realizó el diagnóstico preoperatorio, confirmado mediante tomografía computada. Se realizó diverticulectomía en el 68% de los pacientes y resección segmentaria el 32%. El abordaje fue laparotómico en el 64%, principalmente en el periodo inicial y laparoscópico en el 36%. Hubo una complicación IIIb de Clavien-Dindo en un paciente pediátrico tratado con drenaje percutáneo. En un solo paciente (4%), que se presentó con hemorragia digestiva masiva, se encontró epitelio de tipo gástrico y páncreas ectópico en el divertículo. Conclusiones: En nuestra experiencia el divertículo de Meckel complicado se presentó predominantemente en hombres. La complicación más frecuente en el adulto fue la diverticulitis. El diagnóstico preoperatorio fue infrecuente y realizado por tomografía computada. La diverticulectomía es suficiente en la mayoría de los casos. Actualmente, la laparoscopia es una herramienta segura, rentable y eficiente que permite el diagnóstico y tratamiento oportunos de esta entidad. (AU)

Introduction: Meckel's diverticulum is the most common congenital malformation of the gastrointestinal tract. It can present with bleeding, intesti-nal obstruction or diverticulitis, complications that decrease with age, so in adults the diagnosis is usually incidental. Treatment of complications is surgical, through diverticulectomy or segmental resection of the small intestine, depending on its morphological characteristics. Objective: to analyze our experience in the management of complicated Meckel's diverticulum over a period of 15 years. Design: descriptive, observational, cross-sectional, retrospective study. Materials and methods: the medical records of patients operated on for complicated Meckel's diverticulum in the General Surgery Service of the San Roque Hospital during the period 2007-2022 were reviewed. Demo-graphic data, clinical presentation, preoperative diagnosis, surgical treatment, postoperative complications, and histopathological findings were recorded. Results: twenty-five patients were included, 21 (84%) men, 3 under 18 years of age. The clinical presentation was a right iliac fossa syndrome in 80% of cases, intestinal obstruction in 16% and hemorrhage in 4%. In only 2 cases was the preoperative diagnosis made, confirmed by computed tomography. Diverticulectomy was performed in 68% of patients and segmental resection in 32%. The approach was by laparotomy in 64%, mainly in the initial period, and by laparoscopy in 36%. There was a Clavien-Dindo IIIb complication in a pediatric patient treated with percutaneous drain-age. In only one patient (4%), who presented with massive gastrointestinal bleeding, gastric-type epithelium and ectopic pancreas were found in the diverticulum. Conclusions: In our experience, complicated Meckel's diverticulum occurred predominantly in men. The most frequent complication in adults was diverticulitis. Preoperative diagnosis was infrequent and was made by computed tomography. Diverticulectomy is sufficient in most cases. Currently, laparoscopy is a safe, profitable and efficient tool that allows for the timely diagnosis and treatment of this entity. (AU)

Recommendations from the Spanish Academy of Dermatology and Venereology Psoriasis Working Group on the Management of Patients with Cancer and Psoriasis. / Recomendaciones del Grupo de Psoriasis de la Academia Española de Dermatología y Venereología sobre el manejo de la psoriasis en pacientes oncológicos.

Several studies suggest that patients with psoriasis have a higher incidence of neoplasms, especially of the skin, which could be associated with the use of therapies to treat psoriasis. Furthermore, the evidence available on the safety profile of some treatments in this context, and the management of these patients is scarce, which is why clinical practice guidelines with recommendations on the management of psoriasis in cancer patients are ambiguous. This study provides recommendations on the management and use of the therapies currently available for these patients. They are the result of a Delphi consensus reached by 45 dermatologists of the Spanish Academy of Dermatology and Venereology Psoriasis Working Group, whose goal is to help specialists in the field in their decision-making processes.

Continuous PENG block in an oncologic patient with bilateral femoral avascular necrosis.

The PENG block (pericapsular nerve group) is a recently described technique to address the innervation of the hip, one of the most complex anatomical regions to treat at the locoregional level. We present the case of a patient with acute lymphoblastic leukaemia complicated by avascular necrosis of the bilateral femoral head and previous history of severe chronic pain with probable central sensitization to opioids and a severe thrombocytopenia due to myelotoxicity from chemotherapy treatment. Given the need for orthopaedic surgery to manage femoral necrosis and in anticipation of complex perioperative pain management, a multimodal strategy was planned including bilateral ultrasound-guided continuous PENG blocks to achieve proper pain control in the perioperative period and promote early recovery. The operation and initial recovery were uneventful and the patient was discharged to the ward within 24 h and started early rehabilitation as planned. The patient had a successful recovery with good functionality.

Plant-based diets and their effects on the metabolism and survival of chronic renal patients undergoing conservative treatment

Diet therapy in conservative treatment of chronic kidney disease involves protein restriction, but there is not enough evidence to recommend a particular type of protein, whether animal or plant based. However, studies suggest that plant-based diets help reduce the consumption of total and animal protein, reduce the need for nephroprotective drugs, improve complications and bring advantages in terms of disease progression and patient survival. The article considers up-to-date data on the effects of this diet and observed that when low in protein, primarily vegetable and in some cases supplemented with ketoanalogues, it can result in positive clinical outcomes, such as: delay in the decrease in the glomerular filtration rate, lower concentrations of urea, reduction of serum creatinine and phosphorus concentrations, lower metabolic acidosis, higher insulin sensitivity and lower systemic inflammation. As a whole, this dietary pattern may be able to postpone the start of dialysis with less progression of renal insufficiency. Additional research is needed to better characterize this dietary pattern.

La dietoterapia en el tratamiento conservador de la enfermedad renal crónica implica la restricción de proteínas, pero aún no hay pruebas suficientes para recomendar un tipo concreto de proteínas, ya sean animales o vegetales. Sin embargo, los estudios sugieren que las dietas basadas en plantas ayudan a reducir la ingesta de proteínas totales y animales, disminuyen la necesidad de fármacos nefroprotectores, mejoran las complicaciones y presentan ventajas con respecto a la progresión de la enfermedad y la supervivencia de los pacientes. En este artículo se consideran datos actualizados sobre los efectos de esta dieta y se observa que, cuando es hipoproteica, principalmente vegetal y en algunos casos se complementa con cetoanálogos, puede dar lugar a resultados clínicos positivos, como una disminución retardada de la tasa de filtración glomerular, concentraciones más bajas de urea, concentraciones reducidas de creatinina y fósforo séricos, menor acidosis metabólica, mayor sensibilidad a la insulina y menor inflamación sistémica. En conjunto, este patrón dietético tiene el potencial de retrasar el inicio de la diálisis con una menor progresión de la insuficiencia renal. Es necesario seguir investigando para caracterizar mejor este patrón dietético.

Manejo y resultados de pacientes con diverticulitis aguda: experiencia de cinco años en el Hospital San Vicente Fundación / Management and results of patients with acute diverticulitis. Five year-experience at the San Vicente Fundación Hospital

Introducción. Los datos epidemiológicos de la diverticulitis en Colombia son limitados. El objetivo de este artículo fue caracterizar una población que ingresó con diverticulitis aguda al Hospital Universitario San Vicente Fundación, un centro de referencia de la ciudad de Medellín, Colombia, para analizar la presentación y comportamiento de la enfermedad en la población local, con estadísticas propias y desenlaces de la enfermedad en los últimos años. Métodos. Estudio observacional retrospectivo, descriptivo, entre enero de 2015 y diciembre de 2019. Se hizo un estudio exploratorio uni-, bi- y multivariado de factores de riesgo para fallo en el tratamiento y la mortalidad. Resultados. Se incluyeron 103 pacientes. Se presentó principalmente en mujeres y la edad promedio fue de 65 años. La diverticulitis Hinchey Ia fue la más frecuente (41,7 %) y el manejo médico fue exitoso en todos los casos, mientras que en las tipo III y IV, todos se manejaron de forma quirúrgica, con tasas de éxito entre el 50 y el 64 %. La presencia de signos de irritación peritoneal al examen físico, el recuento de leucocitos y la PCR, el ingreso a la Unidad de Cuidados Intensivos y la mortalidad aumentaron de forma directamente proporcional con el estadio de Hinchey. Conclusiones. Existe una relación directamente proporcional entre la clasificación de Hinchey y los signos de respuesta inflamatoria clínicos y paraclínicos, la necesidad de manejo quirúrgico, la estancia en la Unidad de Cuidados Intensivos y la mortalidad.

Introduction. Epidemiological data on diverticulitis in Colombia are limited. The objective of this article was to characterize a population that was admitted with acute diverticulitis to the San Vicente Fundación University Hospital, a reference center in the city of Medellín, Colombia, to analyze the presentation and behavior of the disease in the local population, with its own statistics, and outcomes of the disease in recent years. Methods. Retrospective descriptive observational study between January 2015 and December 2019. An exploratory uni-, bi- and multivariate study of risk factors for treatment failure and mortality was performed. Results. A total of 103 patients were included. The most frequent Hinchey classification was Ia (41.7%). It occurs mainly in women, mean age 65 years. Hinchey Ia diverticulitis is the most frequent and medical management is successful in 100% of cases; while in III and IV, 100% were managed surgically with success rates between 50 and 64%. The presence of peritoneal signs on physical examination, leukocyte count and CRP, ICU admission and mortality increased directly proportional with Hinchey stage. Conclusions. There is a directly proportional relationship between Hinchey staging with clinical and paraclinical signs of inflammatory response, need for surgical management, ICU stay and mortality.

DNA methylation changes in association with trauma-focused psychotherapy efficacy in treatment-resistant depression patients: a prospective longitudinal study.

Background: Stressful events increase the risk for treatment-resistant depression (TRD), and trauma-focused psychotherapy can be useful for TRD patients exposed to early life stress (ELS). Epigenetic processes are known to be related to depression and ELS, but there is no evidence of the effects of trauma-focused psychotherapy on methylation alterations.Objective: We performed the first epigenome-wide association study to investigate methylation changes related to trauma-focused psychotherapies effects in TRD patients.Method: Thirty TRD patients assessed for ELS underwent trauma-focused psychotherapy, of those, 12 received trauma-focused cognitive behavioural therapy, and 18 Eye Movement Desensitization and Reprocessing (EMDR). DNA methylation was profiled with Illumina Infinium EPIC array at T0 (baseline), after 8 weeks (T8, end of psychotherapy) and after 12 weeks (T12 - follow-up). We examined differentially methylated CpG sites and regions, as well as pathways analysis in association with the treatment.Results: Main results obtained have shown 110 differentially methylated regions (DMRs) with a significant adjusted p-value area associated with the effects of trauma-focused psychotherapies in the entire cohort. Several annotated genes are related to inflammatory processes and psychiatric disorders, such as LTA, GFI1, ARID5B, TNFSF13, and LST1. Gene enrichment analyses revealed statistically significant processes related to tumour necrosis factor (TNF) receptor and TNF signalling pathway. Stratified analyses by type of trauma-focused psychotherapy showed statistically significant adjusted p-value area in 141 DMRs only for the group of patients receiving EMDR, with annotated genes related to inflammation and psychiatric disorders, including LTA, GFI1, and S100A8. Gene set enrichment analyses in the EMDR group indicated biological processes related to inflammatory response, particularly the TNF signalling pathway.Conclusion: We provide preliminary valuable insights into global DNA methylation changes associated with trauma-focused psychotherapies effects, in particular with EMDR treatment.

Stressful events increase treatment-resistant depression, and trauma-focused psychotherapy can be useful for these patients.Epigenome-wide data shows changes associated with trauma-focused psychotherapies, especially eye movement desensitization and reprocessing therapy, in treatment-resistant depression patients.Genes and biological pathways related to inflammatory and immune systems are among the most statistically significant results.

Second radioiodine treatment in patients with differentiated thyroid carcinoma: Causes and effects.

INTRODUCTION: Patients with incomplete response to initial therapy of thyroid cancer can be managed with ongoing observation or potentially additional therapies. Our aim was to assess the effect of a second radioactive iodine treatment (RAIT) and its relationship with causes and clinical variables. MATERIAL AND METHODS: Patients undergoing a second RAIT for biochemical or structural incomplete response to initial therapy of DTC were retrospectively included (n=120). They were categorised based on the American Thyroid Association (ATA) classification of response to initial therapy. Patients were reclassified in the following 6-18 months after second RAIT based on imaging findings and measurements of thyroglobulin and antithyroglobulin antibody levels. The associations of a downgrading of response category and progression-free survival (PFS), and the related variables, were evaluated. RESULTS: Sixty-six patients (55%) had a downgrading on ATA response category after second RAIT. A significant interdependence of causes for second RAIT and outcomes was found (χ2=29.400, p=0.001), with patients with neck reoperation showing a higher rate of indeterminate or excellent responses. A significant association between ATA response to second RAIT and absence of structural progression was found (χ2=44.914, p<0.001), with less structural progression in patients with downgrading on ATA response (χ2=30.914, p<0.001). There was also significant interdependence to some clinical variables, such as AJCC stage (χ2=8.460, p=0.015), ATA risk classification (χ2=10.694, p=0.005) and initial N stage (χ2=8.485, p=0.004). CONCLUSIONS: In selected cases, a second RAIT could lead to more robust responses with a potential improvement in prognosis in patients with incomplete response to initial DTC treatment.
