Pulmonary vascular involvement due to rheumatoid arthritis, presenting as diffuse alveolar haemorrhage (DAH), is a rare phenomenon, especially if there are no signs of systemic vasculitides. Furthermore, how to proceed with the management of these patients is challenging, as in the case of our patient, who had recurrent DAH. We present a case of a patient with known rheumatoid arthritis who had recurrence of DAH that spanned over several years, often presenting with life-threatening respiratory failure. While her DAH presentation improved with high-dose glucocorticoids, to resolve her recurrence, we opted to initiate treatment with rituximab, with a short course of azathioprine...

A 58-year-old man presented with a 6-month history of profound fatigue and a weight loss of 35 to 40 pounds. He reported occasional night sweats and mildly painful knees and elbows without swelling or redness. He denied respiratory symptoms, rashes, or fevers. He had no respiratory symptoms. The patient's history was significant for rheumatoid arthritis (with arthralgias and joint involvement), paroxysmal atrial fibrillation, and hypothyroidism. His medications included digoxin and metoprolol. He had been taking methotrexate and low-dose prednisone (5 mg) for approximately 10 years but discontinued taking these medications 2 years prior to current presentation...

An autoimmune disease is defined as a clinical syndrome resulted from an instigation of both T cell and B cell or individually, in the absence of any present infection or any sort of distinguishable cause. Clonal deletion of auto reactive cells remains the central canon of immunology for decades, keeping the role of T cell and B cell aside, which are actually the guards to recognize the entry of foreign body. According to NIH, 23.5 million Americans are all together affected by these diseases. They are rare, but with the exception of RA...

Phosphodiesterase (PDE) 4 is a superfamily of enzymes that catalyze the hydrolysis of cyclic adenosine 3',5'-monophosphate (cAMP), an intracellular second messenger and regulator of a wide array of genes and proteins. Increased levels of intracellular cAMP lead to activation of genes but also to inhibition of nuclear factor-kappa B, involved in pro-inflammatory responses. By increasing cAMP levels, PDE4 inhibitors, such as apremilast, reduced production of pro-inflammatory TNFα, IFNγ, and IL-17 and increased production of anti-inflammatory IL-10 in lipopolysaccharide-stimulated peripheral blood mononuclear cells, and in patients with psoriatic arthritis (PsA)...

Cardiovascular magnetic resonance imaging is a recently developed noninvasive, nonradiating, operator-independent technique that has been successfully used for the evaluation of congenital heart disease, valvular and pericardial diseases, iron overload, cardiomyopathies, great and coronary vessel diseases, cardiac inflammation, stress-rest myocardial perfusion, and fibrosis. Rheumatoid arthritis and other spondyloarthropathies, systemic lupus erythematosus, inflammatory myopathies, mixed connective tissue diseases (CTDs), systemic sclerosis, vasculitis, and sarcoidosis are among CTDs with serious cardiovascular involvement; this is due to multiple causative factors such as myopericarditis, micro/macrovascular disease, coronary artery disease, myocardial fibrosis, pulmonary hypertension, and finally heart failure...

INTRODUCTION: TNFα-targeted therapies have emerged as a new class of drugs in the treatment of various inflammatory diseases, including psoriasis. With the increasing use and longer follow-up periods of TNFα targeted therapies, a spectrum of immunological adverse events have been described, ranging from asymptomatic immunological alterations to life-threatening systemic diseases such as pulmonary fibrosis. We present a case of a 66 year old man diagnosed with psoriasis who developed pulmonary fibrosis three years after initiation of Etanercept (Enbrel) for his skin disease...

Pneumatosis cystoides intestinalis (PCI) is a rare disease that involves the presence of gas in the intestinal wall. Connective tissue disease (CTD) is a major cause of secondary PCI. In addition to the nature of CTDs, the use of prednisolone and some immunosuppressants, and the presence of complicating diseases such as diabetes mellitus, constipation and pulmonary diseases are involved in the development of PCI. This report describes four cases of PCI with different CTDs (granulomatosis with polyangiitis, rheumatoid arthritis, dermatomyositis, and overlap syndrome) and discusses the background of each patient and common risk factors for the occurrence of PCI...

Interleukin (IL)-32 is a proinflammatory cytokine that is involved in the inflammatory processes of rheumatoid arthritis, chronic obstructive pulmonary disease, and Crohn disease. [1] Recent studies have reported that IL-32 also contributes to the pathophysiology of atopic dermatitis (AD) in the early stages. [2] IL-32 is expressed in the lesional skin of patients with AD and that serum levels of IL-32 in patients with AD are elevated. This article is protected by copyright. All rights reserved.

The introduction of biological therapies into clinical practice has dramatically modified the natural history of chronic inflammatory diseases, such as rheumatoid arthritis (RA). RA is a systemic autoimmune disease that causes articular damage and has a great negative impact on patients' quality of life. Despite the wide spectrum of available biological treatments, ~30% of RA patients are still unresponsive, resulting in high disability and increased morbidity and mortality. In the last few decades, the scientific knowledge on RA pathogenesis vastly improved, leading to the identification of new proinflammatory molecules as potential therapeutic targets...

This chapter describes the involvement of the lung in systemic inflammatory joint disease (IJD) with a particular focus on rheumatoid arthritis, although the topics of pulmonary involvement in ankylosing spondylitis and psoriatic arthritis are also addressed. Interstitial lung disease is the most lethal pulmonary complication of IJD and the chapter describes recent advances in both our understanding of this complication and the therapeutic options that offer real hope for improved outcomes. Although less well recognised, airways disease is just as common and its association with IJD is described in some detail, with a section devoted to the recent surge in interest in bronchiectasis...

Rheumatoid arthritis (RA) is an inflammatory autoimmune disease that can present different extrarticular manifestations involving heart, lungs and kidneys. In recent years there has been a growing awareness of the central role played by the lungs in the onset and progression of RA. In particular interstitial lung disease (ILD) is a common pulmonary manifestation that may be related to the inflammatory process itself, infectious complications and to the treatments used. Management of patients with ILD/RA is still a challenge for clinicians, both synthetic [mainly methotrexate (MTX), leflunomide] and biologic immunosuppressors [mainly anti-tumor necrosis factor (TNF)α] have in fact been related to the onset or worsening of lung diseases with conflicting data...

CD146, a transmembrane glycoprotein member of the immunoglobulin superfamily, acts as an adhesion molecule that helps maintain the cell monolayer. Human endothelial cells expressing CD146 are involved in angiogenesis and inflammation. Recently, we developed a sandwich ELISA for detecting soluble CD146 (sCD146) in human serum specimens. The aim of this study is to determine serum levels of sCD146 in patients with systemic sclerosis (SSc) and to examine the relationship between sCD146 levels and clinical manifestations...

PURPOSE: Methotrexate (MTX) therapy of certain cancers and rheumatoid arthritis often induces serious interstitial lung complications including pulmonary fibrosis. In this study, we investigated the epithelial-mesenchymal transition (EMT) induced by MTX and by transforming growth factor (TGF)-β1 in the human alveolar epithelial cell line A549 in order to develop new strategies for the prevention of EMT. METHODS: First, we examined the effect of TGF-β1 and MTX on cell morphology and the expression of EMT-related mRNAs in A549 cells...

The connective tissue diseases are a variable group of autoimmune mediated disorders characterized by multiorgan damage. Pulmonary complications are common, usually occur after the onset of joint symptoms, but can also be initially presenting complaint. The respiratory system may be involved in all its component: airways, vessels, parenchyma, pleura and respiratory muscles. Lung involvement is an increasing cause of morbidity and mortality in the connective tissue diseases. Clinical course is highly variable - can range from mild to rapidly progressive, some processes are reversible, while others are irreversible...

Patients with rheumatoid arthritis (RA) often have pulmonary involvement, and interstitial lung disease (ILD) is the primary manifestation, in which diffuse alveolar damage (DAD) is a rare histopathologic pattern. Leflunomide (LEF) is a frequently prescribed disease-modifying antirheumatic drug for treating RA. LEF-related ILD in the form of DAD has been reported in patients with RA, with the duration of LEF treatment before symptom onset ranging from 6 to 1204 days.We present a case of elderly woman with RA under prolonged LEF treatment for >9 years (3291 days), who had acute respiratory failure with the initial presentation of exertional dyspnea, fever, chills, and productive cough for 2 days...

Dear Editor, Scleroderma associated with neoplasia is rare, with only a small number of cases reported. We describe 4 patients with paraneoplastic scleroderma who were treated at the I. Department of Dermatovenereology, St. Anna Hospital, during the period between 2004 and 2014. The patients were diagnosed with cholangiogenic carcinoma, endometrial carcinoma, prostatic adenocarcinoma, and adenoma of the suprarenal gland. In the case of concurrent scleroderma and tumor, four situations may occur: they can develop independently of each other; scleroderma may be induced by the tumor; the tumor can develop in the scleroderma; or the tumor can be induced by immunosuppressive therapy...
