OBJECTIVE: Cluster of differentiation 163 (CD163) is a receptor that binds haptoglobin-hemoglobin complexes and is mainly expressed on macrophages and monocytes. As a result of shedding, the extracellular portion of CD163 circulates in the blood as a soluble CD163 (sCD163). This study aimed to measure serum sCD163 levels in patients with systemic sclerosis (SSc) and to assess its association with the clinical, laboratory, and radiological features of the disease. MATERIAL AND METHODS: We measured serum sCD163 levels in 24 patients with SSc and in 30 healthy controls...

BACKGROUND: The correlation of changes (delta: Δ) of high-resolution computed tomography (HRCT) score with the Δ of other clinical variables has not been well studied. The purpose of this study was to determine the correlation of Δ HRCT score with Δ percent predicted forced vital capacity (%pFVC), Δ modified Rodnan Skin Score (mRSS), Δ erythrocyte sedimentation rate (ESR), and Δ percent of oxygen saturation at room air (%SpO2) in patients with early systemic sclerosis (SSc). METHODS: We used an inception cohort of early-SSc patients seen at the Rheumatology Clinic, Chiang Mai University, Thailand, between January 2010 and June 2014...

OBJECTIVE: Increased ventricle volume and brain hypoperfusion are linked to neurodegeneration. We hypothesized that in patients with restricted jugular flow, surgical restoration may reduce brain ventricle volume, because it should improve the pressure gradient, hence promoting cerebrospinal fluid reabsorption into the venous system. METHODS: The effects of restoring the jugular flow were assessed by means of a validated echocardiography with color Doppler (ECD) protocol of flow quantification, magnetic resonance venography, and single-photon emission computed tomography combined with computed tomography (SPECT-CT)...

OBJECTIVES: Left ventricular diastolic dysfunction (LVDD) is more common in systemic sclerosis (SSc) compared to the general population. Focal myocardial ischaemia and fibrosis may be important in its pathogenesis. LVDD is associated with increased mortality and little is known about the risk factors. Advanced SSc lung complications may accompany LVDD. METHOD: We conducted a cross-sectional study of 300 SSc outpatients with and without LVDD, seen between May 2012 and May 2014, and performed univariate and multivariate regression analyses to determine clinical factors associated with LVDD...

BACKGROUND: Acute administration of the oral 5-HT1A receptor agonist buspirone, which is commonly used as an anxiolytic drug, may improve compromised lower esophageal sphincter function. In an open-label trial we assessed the effects of buspirone on esophageal motor function and symptoms in patients with esophageal involvement associated with systemic sclerosis (SSc). METHODS: Thirty consecutive patients with SSc and symptomatic esophageal involvement, despite treatment with proton pump inhibitors, underwent high resolution manometry and chest computed tomography for assessment of motor function and esophageal dilatation, respectively...

BACKGROUND: Patients with idiopathic interstitial pneumonias sometimes have a few features of connective tissue disease (CTD) and yet do not fulfil the diagnostic criteria for any specific CTD. OBJECTIVE: This study was conducted to elucidate the characteristics, prognosis, and disease behavior in patients with interstitial lung disease (ILD) associated with systemic sclerosis (SSc)-related autoantibodies. METHODS: We retrospectively analyzed medical records of 72 ILD patients: 40 patients with SSc (SSc-ILD) and 32 patients with SSc-related autoantibody-positive ILD but not with CTD (ScAb-ILD), indicating lung-dominant CTD with SSc-related autoantibody...

The ivory verterba sign is indicative of diffuse sclerosis of a vertebral body. Though classically associated with osteoblastic metastatic disease, the appearance has also been described with multiple other conditions. Observable on Compute tomography or standard radiography, this sign can serve as a important clue to a systemic disease process.

Systemic sclerosis (SSc) is a multi-systemic autoimmune disease that mainly affects the skin, lungs, gastrointestinal tract, heart and kidneys. Pulmonary disease in patients with SSc is strongly associated with mortality. The mechanisms involved into its pathophysiology include the activation of autoimmune cells and hyperplasia of fibroblasts with an increased capacity to produce collagen and diminished collagen breakdown. Although pulmonary biopsy is the gold standard for the diagnosis of interstitial lung disease in SSc, the most commonly used method is high-resolution computed tomography due to its high sensitivity and specificity...

Tuberous sclerosis complex (TSC) is an uncommon multiorgan disorder that may present many and different manifestations on imaging. Radiology plays an important role in diagnosis and management, and can substantially improve the clinical outcome of TSC. Therefore, a comprehensive understanding of this disease is essential for the radiologist. The manifestations of TSC on computer tomography (CT) and magnetic resonance (MR) images were analyzed. Eleven patients with a clinical diagnosis of TSC were retrospectively reviewed...

Imaging is useful in the diagnosis and management of infections of the central nervous system. Typically, imaging findings at the outset of the disease are subtle and nonspecific, but they often evolve to more definite imaging patterns in a few days, with less rapidity than for stroke but faster than for neoplastic lesions. This timing is similar to that of noninfectious inflammatory brain disease, such as multiple sclerosis. Fortunately, imaging patterns help to distinguish the two kinds of processes. Other than for sarcoidosis, the meninges are seldom involved in noninfectious inflammation; in contrast, many infectious processes involve the meninges, which then enhance with contrast on computed tomography (CT) or magnetic resonance imaging (MRI)...

OBJECTIVE: The current staging system of medicine-related osteonecrosis of the jaws (MRONJ) assigns patients to different stages based on clinical manifestations. The extent of bone disease cannot be fully determined without radiologic evaluation. Missing radiologic information may lead to incorrect classification of MRONJ, resulting in poor outcomes of treatment. The objective of this study was to compare computed tomography (CT) and panoramic radiography (PR) features of MRONJ in different stages to achieve accurate staging on the basis of combined findings from clinical staging and imaging...

Systemic sclerosis (SSc)-associated interstitial lung disease (SSc-ILD) has become the leading SSc-related cause of death. Although various types of immunosuppressive therapy have been attempted for patients with SSc-ILD, no curative or effective treatment strategies for SSc-ILD have been developed. Therefore, management of patients with SSc-ILD remains a challenge. Here, we report a Chinese, female, SSc-ILD patient who was negative for Scl-70 and showed an excellent response to pirfenidone without obvious adverse effects...

PURPOSE OF REVIEW: Interstitial lung disease (ILD) is the major determinant of morbidity and mortality in systemic sclerosis (SSc). In highly selected SSc patients, it was recently shown that stem cell therapy early in the disease course improved survival and reduced the extent of ILD, providing a rationale for early ILD detection strategies in this disease. Here, we review recent progress on ILD screening and early diagnosis in SSc. RECENT FINDINGS: Two studies showed that over 60% of unselected SSc cases with ILD by high-resolution computer tomography (HRCT) had normal range pulmonary function tests (PFTs); indicating poor performance of PFTs for ILD screening purposes...

BACKGROUND: MicroRNA (miRNA) control key elements of mRNA stability and likely contribute to the dysregulated lung gene expression observed in systemic sclerosis associated interstitial lung disease (SSc-ILD). We analyzed the miRNA gene expression of tissue and cells from patients with SSc-ILD. A chronic lung fibrotic murine model was used. METHODS: RNA was isolated from lung tissue of 12 patients with SSc-ILD and 5 controls. High-resolution computed tomography (HRCT) was performed at baseline and 2-3 years after treatment...
