RESUMO
Introducción Según datos de la Organización Mundial de Salud (OMS), el cáncer se ha convertido en una de las primeras causas de muerte a nivel mundial debido al aumento progresivo, si no existe control de su propagación. La valoración conjunta del paciente por parte de distintos especialistas que asumen su abordaje desde diferentes perspectivas, siempre mejora la atención de los mismos y en el caso del paciente oncológico no es una excepción. Objetivo: Caracterizar los pacientes oncológicos que ingresaron por comorbilidades en el Hospital Universitario «Dr. Celestino Hernández Robau» de la provincia Villa Clara. Métodos: Se realizó un estudio descriptivo de corte transversal, en el Hospital Universitario «Dr. Celestino Hernández Robau», de enero a diciembre del 2020, mediante la revisión documental de las historias clínicas al egreso. Resultados: En el sexo femenino, en pacientes de 60 años y más, predominaron los tumores de pulmón, mama y colorrectal, y en el sexo masculino, de pulmón, próstata y hemolinfopoyético El tumor de pulmón fue la localización más frecuente, predominó entre las comorbilidades, las neumonías en pacientes del sexo femenino, mayores de 60 años. Los pacientes ingresados por Diabetes Mellitus, presentaban una enfermedad estable, seguidos por los que se encontraban en progresión, los que ingresaron con insuficiencia cardiaca, presentaban tumor en pulmón o laringe. Conclusiones: Los pacientes que ingresaron por tener tumor de pulmón se asociaron a mayor número de complicaciones y egresos fallecidos. Recomendamos perfeccionar la atención integral de estos pacientes por oncólogos e internistas.
ABTRACT Introduction: according to data from the World Health Organization (WHO), cancer has become one of the leading causes of death worldwide due to its progressive increase, if there is no control of its spread. The joint assessment of the patients by different specialists who assume their approach from different perspectives always improves their care and in the case of cancer patients this is not an exception. Objective: to characterize cancer patients admitted for comorbidities at "Dr. Celestino Hernández Robau" University Hospital in Villa Clara province. Methods: a descriptive cross-sectional study was carried out at "Dr. Celestino Hernández Robau" University Hospital from January to December 2020, through documentary review of the medical records at discharge. Results: females aged 60 years and over predominated; lung, breast, and colorectal tumours predominated in this gender, as well as lung, prostate, and hemolymphopoietic tumours in males. Lung tumour was the most frequent location; pneumonia prevailed among the comorbidities, in females older than 60 years. Patients admitted for diabetes mellitus had a stable disease, followed by those who were in progression; those who were admitted with heart failure had a lung or larynx tumour. Conclusions: patients admitted for having a lung tumour were associated with a greater number of complications and deaths at discharge. We recommend improving a comprehensive care of these patients by oncologists and internists.

Antes de la publicación de la clasificación ATS/ERS 2002 de las neumonías intersticiales idiopáticas (NII), la evaluación histopatológica se consideraba la referencia de oro para el diagnóstico de las enfermedades pulmonares intersticiales (EPI). Sin embargo, varios estudios posteriores mostraron que las concordancias interobservador entre anatomopatólogos expertos torácicos eran sorprendentemente pobres ya que las apariencias histopatológicas pueden superponerse entre entidades distintas. Por lo anterior, se hace necesario un nuevo sistema diagnóstico que sirva de patrón de oro en pacientes con EPI. Es así como nace el concepto de discusión multidisciplinaria, para referirse a una reunión que permita la integración de todos los datos clínicos, radiológicos y patológicos disponibles para un paciente individual y así poder determinar un diagnóstico de trabajo.
Prior to the publication of the 2002 ATS / ERS classification of idiopathic interstitial pneumonias (IIP), the histopathological evaluation was considered the gold standard for the diagnosis of interstitial lung diseases (ILD). However, several subsequent studies showed that interobserver concordances between expert lung pathologists were surprisingly poor, since histopathological appearances may overlap between different entities. Therefore, a new diagnostic system that serves as a gold standard in patients with ILD became necessary. This is how the concept of multidisciplinary discussion was born, to refer to a meeting that allows the integration of all the clinical, radiological and pathological data available for an individual patient and thus be able to determine a working diagnosis.

Interstitial lung diseases are a broad, diverse, challenging group of diseases, most of them chronic whose prognosis is not good. In the last two decades there have been considerable advances in the knowledge of the epidemiology, pathological and genetic bases and treatment of several of these diseases. This article summarizes and presents updated information about their classification, new knowledge on genetics and treatments in idiopathic pulmonary fibrosis, advances in the diagnosis and management of hypersensitivity pneumonitis and a review of the broad spectrum of interstitial diseases associated with connective tissue diseases. Several clinical trials are currently underway whose results will be available in the coming years and will provide more information and tools to improve the treatment of these patients.

OBJECTIVE: To describe the characteristics of a cohort of patients with lung-dominant connective tissue disease (LD-CTD). METHODS: This was a retrospective study of patients with interstitial lung disease (ILD), positive antinuclear antibody (ANA) results (≥ 1/320), with or without specific autoantibodies, and at least one clinical feature suggestive of connective tissue disease (CTD). RESULTS: Of the 1,998 patients screened, 52 initially met the criteria for a diagnosis of LD-CTD: 37% were male; the mean age at diagnosis was 56 years; and the median follow-up period was 48 months. During follow-up, 8 patients met the criteria for a definitive diagnosis of a CTD. The remaining 44 patients comprised the LD-CTD group, in which the most prevalent extrathoracic features were arthralgia, gastroesophageal reflux disease, and Raynaud's phenomenon. The most prevalent autoantibodies in this group were ANA (89%) and anti-SSA (anti-Ro, 27%). The mean baseline and final FVC was 69.5% and 74.0% of the predicted values, respectively (p > 0.05). Nonspecific interstitial pneumonia and usual interstitial pneumonia patterns were found in 45% and 9% of HRCT scans, respectively; 36% of the scans were unclassifiable. A similar prevalence was noted in histological samples. Diffuse esophageal dilatation was identified in 52% of HRCT scans. Nailfold capillaroscopy was performed in 22 patients; 17 showed a scleroderma pattern. CONCLUSIONS: In our LD-CTD group, there was predominance of females and the patients showed mild spirometric abnormalities at diagnosis, with differing underlying ILD patterns that were mostly unclassifiable on HRCT and by histology. We found functional stability on follow-up. Esophageal dilatation on HRCT and scleroderma pattern on nailfold capillaroscopy were frequent findings and might come to serve as diagnostic criteria.

OBJETIVO: Descrever as características de uma coorte de pacientes com colagenose pulmão dominante (CPD). MÉTODOS: Estudo retrospectivo de pacientes com doença pulmonar intersticial (DPI), anticorpo antinuclear (ANA) positivo (≥ 1/320), com ou sem autoanticorpos específicos, e com a presença de ao menos uma manifestação clínica sugestiva de doença do tecido conjuntivo (DTC). RESULTADOS: Dos 1.998 avaliados, 52 preencheram inicialmente os critérios para o diagnóstico de CPD: 37% eram homens; a média de idade ao diagnóstico era de 56 anos e a mediana do tempo de seguimento era de 48 meses. Durante o seguimento, 8 pacientes preencheram os critérios para um diagnóstico definitivo de DTC. Os 44 pacientes restantes formaram o grupo CPD, no qual as manifestações extratorácicas mais prevalentes foram artralgia, doença do refluxo gastroesofágico e fenômeno de Raynaud. Os autoanticorpos mais prevalentes nesse grupo foram ANA (89%) e anti-SSA (anti-Ro, 27%). A média de CVF no início e na última avaliação foi de 69,5% e 74,0% do predito, respectivamente (p > 0,05). Pneumonia intersticial não específica e pneumonia intersticial usual foram identificadas em 45% e 9% das TCARs, respectivamente; 36% das TCARs eram não classificáveis. Uma prevalência semelhante foi identificada na histologia. Dilatação esofágica difusa foi identificada em 52% das TCARs. Capilaroscopia subungueal foi realizada em 22 pacientes; 17 apresentavam um padrão de esclerodermia. CONCLUSÕES: No grupo CPD, houve predominância feminina, e os pacientes apresentaram alterações espirométricas leves ao diagnóstico, com diferentes padrões de DPI, em sua maioria não classificáveis, tanto em TCAR como na histologia. Estabilidade funcional foi identificada no seguimento. A dilatação esofágica em TCAR e o padrão de esclerodermia na capilaroscopia subungueal foram achados frequentes que poderiam servir como critérios diagnósticos. .

Las enfermedades pulmonares intersticiales en el niño, comprenden un gran y heterogéneo grupo de raras enfermedades difusas pulmonares de morbilidad variada. Se caracterizan por cambios inflamatorios y fibróticos que causan remodelación de las paredes alveolares y de las vías respiratorias distales, y ocasionan un defecto restrictivo funcional y una alteración en el intercambio gaseoso, con hipoxemia progresiva. Son muchas las enfermedades que pueden afectar al intersticio pulmonar y múltiples las formas etiológicas causadas por una variedad de procesos patológicos, que incluyen, factores genéticos, asociación a enfermedades sistémicas, así como a respuestas inflamatorias o fibróticas a diferentes estímulos. Sin embargo, algunas veces su origen es desconocido, y se catalogan entonces como idiopáticas. Los neumólogos pediátricos han tratado de clasificar los casos de las enfermedades pulmonares intersticiales en las diferentes categorías descritas originalmente en adultos, pero, en realidad, existen formas del adulto que no se observan en la infancia, y formas únicas de presentación pediátrica. Se señala la importancia del conocimiento de estas entidades, particularmente las de origen desconocido o idiopáticas.
The interstitial pulmonary diseases seen in the child comprise a large heterogeneous group of rare diffuse pulmonary diseases of varied morbidity. They are characterized by inflammatory and fibrotic changes causing remodeling of alveolar walls and of the distal respiratory pathways, leading to restrictive functional defect and altered gas exchange with progressive hypoxemia. Many diseases can affect the pulmonary insterstice and the etiological forms caused by a variety of pathological processes are multiple including genetic factors, association to systemic diseases and inflammatory or fibrotic responses to different stimuli. However, the origin is sometimes unknown, so they are classified as idiopathic diseases. The pediatric pneumologists have tried to classify the interstitial pulmonary disease cases into the originally described categories for adults; however, there are adult forms that do not occur in childhood and unique pediatric presentations that are not seen in adulthood. The importance of knowledge about these diseases, particularly those of unknown or idiopathic origin was stressed in this article.

The initial evaluation of patients with interstitial lung disease (ILD) primarily involves a comprehensive, active search for the cause. Autoantibody assays, which can suggest the presence of a rheumatic disease, are routinely performed at various referral centers. When interstitial lung involvement is the condition that allows the definitive diagnosis of connective tissue disease and the classical criteria are met, there is little debate. However, there is still debate regarding the significance, relevance, specificity, and pathophysiological role of autoimmunity in patients with predominant pulmonary involvement and only mild symptoms or formes frustes of connective tissue disease. The purpose of this article was to review the current knowledge of autoantibody positivity and to discuss its possible interpretations in patients with ILD and without clear etiologic associations, as well as to enhance the understanding of the natural history of an allegedly new disease and to describe the possible prognostic implications. We also discuss the proposition of a new term to be used in the classification of ILDs: lung-dominant connective tissue disease.
A avaliação inicial de pacientes com doença pulmonar intersticial (DPI) envolve primordialmente a busca ativa e detalhada por uma etiologia. A pesquisa rotineira de autoanticorpos é comum em diferentes centros e permite sugerir a presença de alguma doença do espectro reumatológico. Quando o acometimento pulmonar intersticial é a condição que permite o diagnóstico firmado de uma colagenose bem estabelecida, preenchendo os critérios clássicos, há pouco debate. Entretanto, ainda existe muita discussão sobre o significado, a relevância, a especificidade e o papel fisiopatológico da autoimunidade nos pacientes que tenham prioritariamente acometimento respiratório e apenas algum indício leve ou frustro de colagenose. O propósito dessa revisão foi apresentar o conhecimento atual e discutir possibilidades de interpretação da positividade de autoanticorpos em pacientes com DPI que não tenham associações etiológicas inequívocas, assim como aumentar o entendimento da história natural de uma possível nova doença e descrever possíveis implicações prognósticas. Discutimos ainda a proposição de uma nova terminologia na classificação das DPIs, a colagenose pulmão dominante.

Because the superficial lymphatics in the lungs are distributed in the subpleural, interlobular and peribroncovascular interstitium, lymphatic impairment may occur in the lungs of patients with idiopathic interstitial pneumonias (IIPs) and increase their severity. We investigated the distribution of lymphatics in different remodeling stages of IIPs by immunohistochemistry using the D2-40 antibody. Pulmonary tissue was obtained from 69 patients with acute interstitial pneumonia/diffuse alveolar damage (AIP/DAD, N = 24), cryptogenic organizing pneumonia/organizing pneumonia (COP/OP, N = 6), nonspecific interstitial pneumonia (NSIP/NSIP, N = 20), and idiopathic pulmonary fibrosis/usual interstitial pneumonia (IPF/UIP, N = 19). D2-40+ lymphatic in the lesions was quantitatively determined and associated with remodeling stage score. We observed an increase in the D2-40+ percent from DAD (6.66 ± 1.11) to UIP (23.45 ± 5.24, P = 0.008) with the advanced process of remodeling stage of the lesions. Kaplan-Meier survival curves showed a better survival for patients with higher lymphatic D2-40+ expression than 9.3%. Lymphatic impairment occurs in the lungs of IIPs and its severity increases according to remodeling stage. The results suggest that disruption of the superficial lymphatics may impair alveolar clearance, delay organ repair and cause severe disease progress mainly in patients with AIP/DAD. Therefore, lymphatic distribution may serve as a surrogate marker for the identification of patients at greatest risk for death due to IIPs.

OBJECTIVE: The aim of this study was to examine the parenchymal and extracellular matrix remodeling process in two histologic patterns-nonspecific interstitial pneumonia (NSIP) and usual interstitial pneumonia (UIP)-in cases of idiopathic and sclerosis/systemic sclerosis (SSc)-associated interstitial pneumonia. METHODS: We examined 15 cases of idiopathic NSIP, 10 cases of idiopathic UIP, 5 cases of SSc-UIP and 9 cases of SSc-NSIP. In the lung parenchyma, epithelial cells, endothelial cells and myofibroblasts were evaluated by immunohistochemical staining, whereas histochemical staining was used in order to evaluate collagen/elastic fibers in the extracellular matrix. RESULTS: The percentage of surfactant protein A-positive epithelial cells was significantly greater in idiopathic NSIP than in SSc-NSIP, as well as being greater in idiopathic UIP than in SSc-UIP. Idiopathic NSIP and idiopathic UIP presented significantly higher immunoexpression of alpha smooth muscle actin in myofibroblasts than did SSc-NSIP and SSc-UIP. The percentage of CD34 endothelial cells in the pulmonary microvasculature was significant lower in idiopathic UIP than in SSc-UIP. The density of collagen fibers was significantly greater in idiopathic NSIP and idiopathic UIP than in SSc-NSIP and UIP. In contrast, the elastic fiber density was significantly lower in idiopathic UIP than in SSc-UIP. CONCLUSIONS: Increased collagen synthesis, destruction of elastic fibers, high myofibroblast proliferation and poor microvascularization might represent a remodeling process found in idiopathic interstitial pneumonia, whereas the reverse might represent a repair process in SSc-associated interstitial pneumonia.
OBJETIVO: O objetivo deste trabalho foi examinar o processo de remodelamento no parênquima e na matriz extracelular em dois padrões histológicos-pneumonia intersticial não-específica (PINE) e pneumonia intersticial usual (PIU)-em casos associados à esclerose idiopática/esclerose sistêmica (ES). MÉTODOS: Investigamos 15 casos de PINE idiopática, 10 casos de PIU idiopática, 5 casos de PIU associada à ES (PIU-ES) e 9 de PINE associada à ES (PINE-ES). No parênquima pulmonar, as células epiteliais, células endoteliais e miofibroblastos foram avaliados através de coloração imuno-histoquímica, ao passo que a coloração histoquímica foi utilizada para avaliar as fibras elásticas e de colágeno na matriz extracelular. RESULTADOS: A porcentagem de células epiteliais positivas para proteína A do surfactante foi significativamente maior nos casos de PINE idiopática do que nos de PINE-ES, assim como nos casos de PIU idiopática do que nos de PIU-ES. A PINE e a PIU idiopáticas apresentaram valores significativamente maiores de imunoexpressão de alfa actina de músculo liso nos miofibroblastos do que a PINE-ES e a PIU-ES. A porcentagem de células endoteliais CD34 na microvasculatura pulmonar foi significativamente menor na PIU idiopática do que na PIU-ES. A densidade de fibras do colágeno foi significativamente maior em ambas as formas idiopáticas de PINE e PIU do que na PINE-ES e PIU-ES. Em contraste, a densidade de fibras elásticas foi significativamente menor na PIU idiopática do que na PIU-ES. CONCLUSÕES: A síntese aumentada de colágeno, a destruição de fibras elásticas, a alta proliferação miofibroblástica e a microvascularização diminuída podem representar um processo de remodelamento encontrado na pneumonia intersticial idiopática, enquanto o reverso pode representar mais um processo de reparo na pneumonia intersticial associada à ES.
