BACKGROUND: There is yet no gold standard for the diagnosis of acute-onset autoimmune hepatitis (A-AIH), especially histologically acute AIH. As a result, long-term observation of A-AIH has been difficult and the nature is not well known. We retrospectively analyzed the clinicopathological features of A-AIH over a long prospective follow-up period. METHODS: Clinical, biochemical, immunological and pathological features of 30 patients (21 female, mean age 55.1 ± 13...

Wound infection has been a persistent problem that is common and costly. Thermosensitive hydrogel has been demonstrated to be a suitable dressing candidate due to its high moldability, easy administration and ability to maintain a moist topical environment at the wound bed. In the present study, a novel thermosensitive hydrogel was successfully prepared and characterized to have a porous inner structure and a sustained curcumin-releasing profile. The wound healing ability of the hydrogel was investigated in a wound infection model in rats...

BACKGROUND: Mortality is similarly high among individuals with usual interstitial pneumonia (UIP) due to idiopathic pulmonary fibrosis (IPF) and interstitial pneumonia with autoimmune features (IPAF). Circulating anti-nuclear antibodies (ANA) are commonly found in this patient population, suggesting possible aberrant immune activation. Because an environment of oxidative stress can result from immunologic activation, we hypothesized that ANA positive patients with UIP would have improved outcome when exposed to the antioxidant N-acetylcysteine (NAC) compared to ANA negative patients...

Paraneoplastic rheumatic syndromes comprise a heterogeneous group of disorders characterized by typical rheumatic manifestations but without direct invasion by the tumor or metastases. The clinical features and malignancy-associated risk factors of 21 patients with paraneoplastic rheumatic syndromes, including 11 men and 10 women with a mean age of 56.3 ± 13.1 years, were characterized by a retrospective review. All patients were diagnosed with malignancy within 2 years of rheumatism diagnosis. Patients suffering from solid malignancies accounted for the majority (62%); hematological malignancies were observed in the remainder...

BACKGROUND AND OBJECTIVE: Criteria for interstitial pneumonia with autoimmune features (IPAF) were recently established for research purposes in a joint statement from the European Respiratory Society (ERS) and American Thoracic Society (ATS). We reviewed the utility of these criteria in patients previously diagnosed as broadly defined undifferentiated connective tissue disease (UCTD) and noted overlapping IPAF findings. Additional review was given to IPAF patients with usual interstitial pneumonia (UIP) on histopathology or radiology in terms of survival and outcome...

BACKGROUND: There have been several reports on dasatinib-induced reversible pulmonary hypertension. This is the first reported case in Latvia; the patient did not discontinue the drug after the first adverse effects in the form of pleural effusions, which we speculate led only to partial reversion of the disease. CASE PRESENTATION: A 67-year-old white man with chronic myelogenous leukemia was treated with the dual Src and BCR-ABL tyrosine kinase inhibitor dasatinib...

BACKGROUND/AIM: Probably due to their low occurrence, chromophobe and papillary renal cell carcinomas are less well characterized and, currently, there are no reliable prognostic markers for this group of patients. Moreover, the optimal therapy for patients with non-clear renal cell carcinoma (RCC) is unknown yet. Although elevated levels of Galectin-3 (Gal-3) were associated with poor prognosis in conventional RCC, the impact of this protein on carcinogenesis of chromophobe and papillary entities has not been previously described...

Fluoro-edenite (FE) is an asbestiform mineral fiber spotted in the lava rocks excavated from a stone quarry in Biancavilla (Italy). The derived material had been employed locally for building purposes. Previous studies found evidence that exposure to asbestos may induce autoimmunity, with frequency of anti-nuclear autoantibodies (ANA). The aim of this study was to explore the relationship between FE exposure and autoimmune responses in an exposed population. For the study, 60 subjects living in the area of Biancavilla and 60 subjects as control group were randomly invited to participate...

BACKGROUND: Identification of myositis-specific autoantibodies (MSA) for dermatomyositis (DM) could allow the characterization of an antibody-associated clinical phenotype. OBJECTIVE: We sought to define the clinical phenotype of DM and the risk of cancer, interstitial lung disease (ILD) and calcinosis based on MSA. METHODS: A 3.5-year multicenter prospective study of adult DM patients was conducted to determine the clinical phenotype associated with MSA and the presence of cancer, ILD and calcinosis...

BACKGROUND: The effects of corticosteroid-based therapy in patients with idiopathic nonspecific interstitial pneumonia (iNSIP), and factors affecting treatment outcome, are not fully understood. We aimed to investigate the long-term treatment response and factors affecting the treatment outcome in iNSIP patients from a multi-center study in Korea. METHODS: The Korean interstitial lung disease (ILD) Study Group surveyed ILD patients from 2003 to 2007. Patients were divided into two groups to compare the treatment response: response group (forced vital capacity (FVC) improves ≥10% after 1 year) and non-response group (FVC <10%)...

Background: Multiple sclerosis and other demyelinating processes are sometimes difficult to differentiate from the neurological involvement in autoimmune diseases. Distinguishing multiple sclerosis from other lesions due to autoimmune diseases is crucial to avoid unsuitable or delayed treatments. Methods: Charts of 6 patients diagnosed with mimicking multiple sclerosis between 1996 and 2014 were retrospectively assessed. Results: The mean age at diagnosis was 35±7 years...

Mouse models have contributed to the bulk of knowledge on Systemic Lupus Erythematosus (SLE). Nevertheless, substantial differences exist between human and mouse immune system. We aimed to establish and characterise a SLE model mediated by human immune system. Injection of pristane into immunodeficient mice reconstituted with human immune system (humanised mice) recapitulated key SLE features, including: production of human anti-nuclear autoantibodies, lupus nephritis, and pulmonary serositis. There was a reduction in the number of human lymphocytes in peripheral blood, resembling lymphopenia in SLE patients...

The evolutional process of disease-associated autoantibodies in systemic lupus erythematosus (SLE) remains to be established. Here we show intraclonal diversification and affinity maturation of anti-nuclear antibody (ANA)-producing B cells in SLE. We identified a panel of monoclonal ANAs recognizing nuclear antigens, such as double-stranded DNA (dsDNA) and ribonucleoproteins (RNPs) from acute SLE subjects. These ANAs had relatively few, but nonetheless critical mutations. High-throughput immunoglobulin sequencing of blood lymphocytes disclosed the existence of sizable ANA lineages shearing critical mutations intraclonally...

BACKGROUND: Cancer is a significant complication contributing to increased mortality in idiopathic inflammatory myopathies (IIMs), and the association between IIMs and cancer has been extensively reported. Myositis-specific autoantibodies (MSAs) can help to stratify patients into more homogeneous groups and may be used as a biomarker for cancer-associated myositis. In this study, we aimed to systematically define the cancer-associated MSAs in IIMs. METHODS: Serum from 627 patients with IIMs was tested for MSAs...

Determinants of changes in disease activity among patients with juvenile dermatomyositis (JDM) are unknown. Our objective was to develop predictive models to predict changes in disease activity using the CARRA Legacy Registry. The CARRA Legacy Registry included 658 subjects with definite or probably JDM with 297 subjects with a one follow-up visit after baseline, and we studied the 65 subjects with active disease at baseline. Linear regression models were used to build risk scores for changes in disease activity adjusted for baseline disease activity, age, sex, and disease duration...
