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.

Diagnosis and treatment of interstitial lung disease: focusing on idiopathic pulmonary fibrosis

Interstitial lung disease (ILD) is a rare condition characterized by extensive inflammation and fibrosis mainly involving the pulmonary interstitium or alveoli. Usually, patients with ILD clinically present with chronic cough and exertional dyspnea. ILD is classified into subtypes based on clinical characteristics, detailed history obtained from patients, and radiological, and/or histopathological features. The most common type of idiopathic interstitial pneumonia is idiopathic pulmonary fibrosis (IPF). IPF is a chronic progressive fibrosing ILD and is associated with poor prognosis. An exclusive diagnosis of IPF requires no known condition causing ILD and typical radiological and/or histopathological features of lung fibrosis. Fibrosis observed in this condition is attributable to repetitive epithelial injury with consequent abnormal wound healing in genetically susceptible and elderly individuals. Currently, pirfenidone and nintedanib are useful disease-modifying agents available to treat IPF. In this article, we review the concept, diagnosis, clinical course, and treatment of ILD.

Korean Guidelines for Diagnosis and Management of Interstitial Lung Diseases: Part 1. Introduction / 결핵

Idiopathic interstitial pneumonia (IIP) is a histologically identifiable pulmonary disease without a known cause that usually infiltrates the lung interstitium. IIP is largely classified into idiopathic pulmonary fibrosis, idiopathic non-specific interstitial pneumonia, respiratory bronchiolitis-interstitial lung disease (ILD), cryptogenic organizing pneumonia, desquamative interstitial pneumonia, and acute interstitial pneumonia. Each of these diseases has a different prognosis and requires specific treatment, and a multidisciplinary approach that combines chest high-resolution computed tomography (HRCT), histological findings, and clinical findings is necessary for their diagnosis. Diagnosis of IIP is made based on clinical presentation, chest HRCT findings, results of pulmonary function tests, and histological findings. For histological diagnosis, video-assisted thoracoscopic biopsy and transbronchial lung biopsy are used. In order to identify ILD associated with connective tissue disease, autoimmune antibody tests may also be necessary. Many biomarkers associated with disease prognosis have been recently discovered, and future research on their clinical significance is necessary. The diagnosis of ILD is difficult because patterns of ILD are both complicated and variable. Therefore, as with other diseases, accurate history taking and meticulous physical examination are crucial.

Korean Guidelines for Diagnosis and Management of Interstitial Lung Diseases: Part 3. Idiopathic Nonspecific Interstitial Pneumonia / 결핵

Idiopathic nonspecific interstitial pneumonia (NSIP) is one of the varieties of idiopathic interstitial pneumonias. Diagnosis of idiopathic NSIP can be done via multidisciplinary approach in which the clinical, radiologic, and pathologic findings were discussed together and exclude other causes. Clinical manifestations include subacute or chronic dyspnea and cough that last an average of 6 months, most of which occur in non-smoking, middle-aged women. The common findings in thoracic high-resolution computed tomography in NSIP are bilateral reticular opacities, traction bronchiectasis, reduced volume of the lobes, and ground-glass opacity in the lower lungs. These lesions can involve diffuse bilateral lungs or subpleural area. Unlike usual interstitial pneumonia, honeycombing is sparse or absent. Pathology shows diffuse interstitial inflammation and fibrosis which are temporally homogeneous, namely NSIP pattern. Idiopathic NSIP is usually treated with steroid only or combination with immunosuppressive agents such as azathioprine, cyclophosphamide, cyclosporine, and mycophenolate mofetil. Prognosis of idiopathic NSIP is better than idiopathic pulmonary fibrosis. Many studies have reported a 5-year survival rate of more than 70%.

Korean Guidelines for Diagnosis and Management of Interstitial Lung Diseases: Part 5. Connective Tissue Disease Associated Interstitial Lung Disease / 결핵

Connective tissue disease (CTD) is a collection of disorders characterized by various signs and symptoms such as circulation of autoantibodies in the entire system causing damage to internal organs. Interstitial lung disease (ILD) which is associated with CTD is referred to as CTD-ILD. Patients diagnosed with ILD should be thoroughly examined for the co-occurrence of CTD, since the treatment procedures and prognosis of CTD-ILD are vary from those of idiopathic interstitial pneumonia. The representative types of CTD which may accompany ILD include rheumatoid arthritis, systemic sclerosis (SSc), Sjögren's syndrome, mixed CTD, idiopathic inflammatory myopathies, and systemic lupus erythematous. Of these, ILD most frequently co-exists with SSc. If an ILD is observed in the chest, high resolution computed tomography and specific diagnostic criteria for any type of CTD are met, then a diagnosis of CTD-ILD is made. It is challenging to conduct a properly designed randomized study on CTD-ILD, due to low incidence. Therefore, CTD-ILD treatment approach is yet to been established in absence of randomized controlled clinical trials, with the exception of SSc-ILD. When a patient is presented with acute CTD-ILD or if symptoms occur due to progression of the disease, steroid and immunosuppressive therapy are generally considered.

Artritis reumatóide de inicio tardío asociada a enfermedad pulmonar intersticial / Late onset rheumatoid arthritis associated with interstitial lung disease

RESUMEN La artritis reumatoide de inicio tardío es considerada en la población mayor de 65 arios, presentando diferencias a las manifestaciones clínicas y de laboratorio respecto a la artritis reumatoide en población joven, con mayor riesgo de presentar formas agresivas de la enfermedad y de comenzar con un compromiso sistémico. Se establece en este caso clínico la presencia de una probable relación entre la enfermedad pulmonar intersticial asociada con artritis reumatoide de inicio tardío. En la mayoría de casos la afectación pulmonar se presenta posterior al compromiso articular, aunque puede aparecer simultáneamente e incluso ser la primera manifestación. Los hallazgos patológicos de las manifestaciones pulmonares asociadas con enfermedades autoinmunes son similares a las neumonías intersticiales idiopáticas. Se describe el caso de una paciente que presenta compromiso pulmonar por neumonía intersticial idiopática y posteriormente presenta dolor articular, por lo que se documentó artritis reumatoide.

ABSTRACT Rheumatoid arthritis of late onset occurs in the population over 65 years of age, presenting differences in clinical and laboratory manifestations compared to rheumatoid arthritis in younger people, with a higher risk of presenting with aggressive forms of the disease, and with systemic compromise. The presence of a probable relationship between the interstitial lung disease associated with late-onset rheumatoid arthritis is established in this case. In most cases pulmonary involvement occurs after the joint problems, although they may appear simultaneously, and may even be the first manifestation. Pathological findings in interstitial pneumonias associated with collagen diseases are similar to idiopathic interstitial pneumonias. A case is presented of a woman who had pulmonary involvement due to idiopathic interstitial pneumonia, and subsequently presented with joint pain with rheumatoid arthritis being documented.

Adolescente con fibroelastosis pleuroparenquimatosa idiopatica: A propòsito de un caso / An adolescent with idiopathic pleuroparenchymal fibroelastosis: Case report

La fibroelastosis pleuroparenquimatosa idiopàtica (FEPPI) es un trastorno raro incluido recientemente en las neumonías intersticiales idiopáticas según la actualización de la clasificación de la Sociedad Torácica Estadounidense (American Thoracic Society) y la Sociedad Respiratoria Europea (European Respiratory Society). La FEPPI se caracteriza por fibrosis parenquimatosa pleural y subpleural que produce reducción del volumen, sobre todo en los lóbulos pulmonares superiores. La edad al momento de la aparición varía, aunque la FEPPI ocurre principalmente entre los 30 y los 50 años de edad. En este artículo, presentamos el caso de un paciente de 16 años con antecedentes de disnea de esfuerzo, tos seca y pérdida de peso en los últimos dos años. Durante el examen físico, con la auscultación se detectó disminución de los ruidos respiratorios en los lóbulos superiores. En la radiografía de tórax se observó engrosamiento pleural apical y volumen reducido. En la tomografia computarizada (TC) del tórax se observaron densidades en vidrio esmerilado y bronquiectasia tubular predominantemente en ambos lóbulos superiores, con engrosamiento septal interlobulillar de la pleura y adenopatía mediastínica. Se realizó una biopsia pulmonar por toracoscopia y en el examen histológico se observaron fibrosis subpleural y tinción de las fibras elásticas que demostraba depósito de fibras elásticas en el área subpleural y el parénquima pulmonar adyacente, lo que sugería FEPPI. Hasta donde sabemos, este es el primer caso durante la niñez. Por lo tanto, los pediatras deben estar atentos a esta enfermedad para realizar un diagnóstico y tratamiento adecuados.

Idiopathic pleuroparenchymal fibroelastosis (IPPFE) is a rare disorder recently included in rare idiopathic interstitial pneumonias according to the updated American Thoracic Society/European Respiratory Society classification. IPPFE is characterized by pleural and subpleural parenchymal fibrosis causing volume loss predominantly in the upper lung lobes. Age of onset is variable, IPPFE mainly occurs in third and fourth decades. We present a 16 year old patient with a 2-year history of exertional dyspnea, nonproductive cough and weight loss. On physical examination, auscultation revealed diminished breath sounds on the upper lobes.Chest radiograph showed apical pleural thickening and volume loss. Computerized tomographic scan (CT) of chest revealed ground glass densities and tubular bronchiectasis predominantly in upper lobes bilaterally, with interlobular septal thickening of the pleura and enlarged mediastinal lymph nodes. Thoracoscopic lung biopsy was performed and histological evaluation showed subpleural fibrosis and elastic staining demonstrated fragmented elastic fiber deposition in the subpleural area and adjacent pulmonary parenchyma suggesting IPPFE. To our knowledge this is the first case in childhood. Therefore, pediatricians should be aware of this disease for the diagnosis and appropriate management.

Clinical Outcomes of Lung Transplantation: Experience at Asan Medical Center / 대한흉부외과학회지

BACKGROUND: Lung transplantation is a life-saving procedure in patients with end-stage lung disease, and is increasingly performed in Korea. METHODS: We retrospectively evaluated the outcomes of patients who received a lung transplant at Asan Medical Center between January 2008 and December 2016. Thirteen of 54 patients experienced multiorgan transplantation; the remaining 41 who received only lung grafts were included. RESULTS: The mean age of the lung transplant recipients was 44.6 years; 27 were men and 14 were women. The most frequent reasons were idiopathic interstitial pneumonia (21 of 41 patients, 51.2%), interstitial lung disease (9 of 41, 22.0%), and bronchiolitis obliterans after bone marrow transplantation (7 of 41, 17.1%). The median waiting time was 47 days, and many patients received preoperative intensive care (27 of 41, 65.9%), ventilator support (26 of 41, 63.4%), or extracorporeal life support (19 of 41, 46.3%). All 41 patients received bilateral lung grafts. Ten deaths occurred (24.3%), including 5 cases of early mortality (12.2%) and 5 cases of late mortality (12.2%). The 1-, 3-, and 5-year survival rates were 78.9%, 74.2%, and 69.3%, respectively. CONCLUSION: Despite a high percentage of patients who required preoperative intensive care, the transplantation outcomes were acceptable.

A Case of Desquamative Interstitial Pneumonia with an Increased Number of Eosinophils in Bronchoalveolar Lavage Fluid / 대한내과학회지

Here, we present a case of desquamative interstitial pneumonia (DIP) that was initially misdiagnosed as chronic eosinophilic pneumonia due to an increased number of eosinophils in the bronchoalveolar lavage fluid (BALF). A 56-year-old male smoker presented with a productive cough that had been present for 1 month. High-resolution computed tomography (HRCT) revealed multifocal patchy ground-glass and reticular opacities in the subpleural area. BALF analysis revealed an elevated level of eosinophils (37%). Thus, the patient was initially diagnosed with chronic eosinophilic pneumonia and was administered prednisolone (0.5 mg/kg/day). However, his symptoms and the diffuse infiltrative shadows on HRCT did not improve after 2 months of treatment, and a video-assisted thoracoscopic lung biopsy led to the diagnosis of DIP. Prednisolone (1 mg/kg/day) was administered again, and the patient's symptoms improved. At 1 year after the end of treatment, the patient remained symptom-free.

Different Responses to Clarithromycin in Patients with Cryptogenic Organizing Pneumonia / 결핵및호흡기질환

Cryptogenic organizing pneumonia (COP) is an idiopathic interstitial pneumonia characterized by a subacute course and favorable prognosis with corticosteroids. However, some patients show resistance to steroids. Macrolides have been used with success in those patients showing resistance to steroids. A few reports showed treatment failure with macrolides in patients with COP who were resistant to steroids. In this report, we described two cases of COP who showed different responses to clarithromycin. One recovered completely, but the other gradually showed lung fibrosis with clarithromycin.

Interstitial Lung Disease in Connective Tissue Disease

Interstitial lung disease (ILD) is one of the most serious pulmonary complications of connective tissue diseases (CTDs), resulting in significant morbidity and mortality. ILD is frequently seen in CTDs, particularly systemic sclerosis, polymyositis/dermatomyositis, and rheumatoid arthritis; however, determining that ILD is associated with an established CTD requires the exclusion of alternative causes. Non-specific interstitial pneumonia is the most commonly observed histopathological pattern in CTD-associated ILD (CTD-ILD) except for rheumatoid arthritis, characterized by a higher frequency of usual interstitial pneumonia. Although CTD-ILD usually shows a stable or slowly progressive course, a subgroup exhibits a more severe and progressive course and requires pharmacologic intervention. Treatment strategies typically involve empirical use of immunosuppressive therapies, although a large, randomized study has examined the impact of immunosuppressive therapy for systemic sclerosis associated ILD and should also address comorbid conditions considering implementation of adjunctive therapeutic strategies. A subgroup of patients with idiopathic interstitial pneumonia who meet some, but not all, diagnostic criteria for CTDs were identified and well organized prospective studies are needed in to better determine whether evidence of autoimmunity in those plays a part in the evolution to well-defined CTDs or carries prognostic significance.

Idiopathic Pleuroparenchymal Fibroelastosis Presenting in Recurrent Pneumothorax: A Case Report / 결핵및호흡기질환

Idiopathic pleuroparenchymal fibroelastosis (PPFE) is a rare, recently classified entity that consists of pleural and subjacent parenchymal fibrosis predominantly in the upper lungs. In an official American Thoracic Society/European Respiratory Society statement in 2013, this disease is introduced as a group of rare idiopathic interstitial pneumonias. We describe a case of a 76-year-old woman with cough and recurrent pneumothorax. She was admitted to our hospital with severe cough at first. High resolution computed tomography (HRCT) disclosed multifocal subpleural consolidations with reticular opacities in both lungs, primarily in the upper lobes, suggesting interstitial pneumonia. Rheumatoid lung was diagnosed initially through an elevated rheumatoid factor, HRCT and surgical biopsy at the right lower lobe. However, one month later, pneumothorax recurred. Surgical biopsy was performed at the right upper lobe at this time. The specimens revealed typical subpleural fibroelastosis. We report this as a first case of idiopathic PPFE in Korea after reviewing the symptoms, imaging and pathologic findings.

Clinical Significance of Serum Autoantibodies in Idiopathic Interstitial Pneumonia

Although autoantibodies are routinely screened in patients with idiopathic interstitial pneumonia, there are no reliable data on their clinical usefulness. The aim of this study was to investigate the prognostic value of autoantibodies for predicting the development of new connective tissue disease in these patients and also mortality. We conducted retrospective analysis of the baseline, and follow-up data for 688 patients with idiopathic interstitial pneumonia (526 with idiopathic pulmonary fibrosis, 85 with nonspecific interstitial pneumonia, and 77 with cryptogenic organizing pneumonia) at one single tertiary referral center. The median follow-up period was 33.6 months. Antinuclear antibody was positive in 34.5% of all subjects, rheumatoid factor in 13.2%, and other specific autoantibodies were positive between 0.7%-6.8% of the cases. No significant difference in patient survival was found between the autoantibody-positive and -negative groups. However, the presence of autoantibodies, especially antinuclear antibody with a titer higher than 1:320, was a significant predictor for the future development of new connective tissue diseases (relative risk, 6.4), although the incidence was low (3.8% of all subjects during follow-up). In conclusion, autoantibodies are significant predictors for new connective tissue disease development, although they have no prognostic value.

A Case of Bronchiolitis Interstitial Pneumonitis / 대한내과학회지

Interstitial lung diseases are diagnosed based on clinical, radiological, and histopathological findings. There are various kinds of interstitial lung diseases involving both the interstitium and bronchioles. Bronchiolitis interstitial pneumonitis (BIP) was recently reported as an independent disease cluster combined with both interstitial pneumonitis and bronchiolitis, which is not classified in a specific category of idiopathic interstitial pneumonia (IIP) by the present classification. In this case report, we introduce a recently experienced patient with BIP. A 68-year-old female visited our hospital with aggravated dyspnea for the past 2 months. Her chest computed tomography scan compared to 6 months ago showed increased reticulonodular lesion and ground glass opacities, suggesting interstitial lung disease. A video-assisted thoracoscopic biopsy from a right lower lobe wedge resection resulted in the diagnosis of BIP. Clinical symptoms, pulmonary lesions, and pulmonary function test results remained stable for 1.5 years after oral glucocorticoid and immunosuppressive therapy.

Radiologic Approach to the Idiopathic Interstitial Pneumonias / 대한내과학회지

Idiopathic interstitial pneumonias (IIP), a heterogeneous group of diffuse parenchymal lung diseases, include seven clinicopathologic entities: idiopathic pulmonary fibrosis (IPF), nonspecific interstitial pneumonia (NSIP), cryptogenic organizing pneumonia (COP), acute interstitial pneumonia (AIP), respiratory bronchiolitis (RB)-associated interstitial lung disease (ILD), desquamative interstitial pneumonia (DIP), and lymphoid interstitial pneumonia (LIP). Each of these entities has a typical histologic pattern that correlates well with imaging features. Thus, imaging plays an essential role in classifying and differentiating this group of diseases. The characteristic HRCT findings of IPF are reticular opacity with honeycombing and traction bronchiectasis in a predominantly basal and peripheral distribution. NSIP manifests as basal ground-glass opacity and reticular opacity. Honeycombing is rare. COP is characterized by patchy peripheral or peribronchovascular consolidation. AIP appears as extensive, mixed ground-glass opacity and consolidation. RB-ILD and DIP are smoking-related diseases associated with CT features of poorly defined centrilobular nodules and ground-glass opacity. LIP is a rare disease characterized by ground-glass opacity sometimes associated with perivascular cysts. Although some of idiopathic interstitial pneumonias may show diagnostic CT features, the final diagnosis of IIPs is usually made by means of evaluation of all the combined clinical, radiologic, and pathologic findings.

Treatment Response and Long Term Follow-up Results of Nonspecific Interstitial Pneumonia

The purpose of this study was to investigate the long-term clinical course of non-specific interstitial pneumonia (NSIP) and to determine which factors are associated with a response to steroid therapy and relapse. Thirty-five patients with pathologically proven NSIP were included. Clinical, radiological, and laboratory data were reviewed retrospectively. The male-to-female ratio was 7:28 (median age, 52 yr). Thirty (86%) patients responded to steroid therapy, and the median follow-up was 55.2 months (range, 15.9-102.0 months). Five patients (14%) showed sustained disease progression and three died despite treatment. In the five with sustained disease progression, NSIP was associated with various systemic conditions, and the seropositivity of fluorescent antinuclear antibody was significantly associated with a poor response to steroids (P = 0.028). The rate of relapse was 25%, but all relapsed patients improved after re-treatment. The initial dose of steroids was significantly low in the relapse group (P = 0.020). In conclusion, progression is associated with various systemic conditions in patients who show progression. A low dose of initial steroids is significantly associated with relapse.

Intralobar Pulmonary Sequestration Showing Increased Serum CA19-9 / 결핵및호흡기질환

Carbohydrate antigen 19-9 (CA19-9) is a specific tumor marker of the biliary, pancreatic and gastrointestinal tracts. CA19-9 is occasionally elevated in serum in patiens with benign pulmonary diseases such as bronchiectasis, idiopathic interstitial pneumonia or collagen disease-associated pulmonary fibrosis. Intralobar pulmonary sequestration is an uncommon congenital lung anomaly. It is dissociated from the normal tracheobronchial tree and is supplied by an anomalous systemic artery. There have been some reports of elevation of CA19-9 in this lesion. We report a case of intralobar pulmonary sequestration with elevated serum CA19-9 in a 29-year-old man who was diagnosed with bronchiectasia of left lower lung field on general check up. He had no evidence of any malignant disease in pancreatobiliary or gastrointestinal tracts. Elevated serum CA19-9 level might be encountered with benign pulmonary disease such as pulmonary sequestration.

A Case of Asymptomatic, Localized, and Idiopathic Diffuse Alveolar Damage / 결핵및호흡기질환

Diffuse alveolar damage (DAD) is a histological change in lung tissue, and is generally caused by an acute lung injury, which is characterized by bilateral and widespread damages. Localized DAD occurs very rarely. The causes for DAD are numerous, but the chief cause is acute interstitial pneumonia or acute exacerbation of idiopathic interstitial pneumonia, in cases of idiopathic manifestation. The 82-year-old patient, in this case study, showed a DAD lesion in only 1 lobe. The patient was otherwise healthy, with no previous symptoms of DAD. He was admitted to our medical center owing to localized infiltration, observed on his chest radiograph. Laboratory studies showed no signs of infections. DAD was confirmed by a surgical lung biopsy. The patient received corticosteroid treatment and had gradually improved. We report the case of a patient with localized, idiopathic DAD that cannot be classified as acute interstitial pneumonia or acute exacerbation of idiopathic interstitial pneumonia.
