961 described in SSc patients with pulmonary fibrosis's or by spontaneous release of interleukin-1 since these alterations may enhance T helper cell function in antibody synthesis. This report emphasizes that antinuclear anti-Scl-70 antibodies may distinguish not only the diffuse cutaneous subset of SSc, but also patients at risk ofdeveloping severe lung disease.

OBJECTIVE To investigate the prevalence and normal versus abnormal levels of anticardiolipin antibodies (aCL) in a healthy adult population of Omanis and whether a correlation exists between aCL and antinuclear antibodies (ANA) in this Omani population. METHODS A total of 521 healthy Omani individuals (333 males and 188 females), aged between 17-54-years were investigated for the presence and...

G-quadruplex-forming oligonucleotides containing modified nucleotide chemistries have demonstrated promising pharmaceutical potential. In this work, we systematically investigate the effects of sugar-modified guanosines on the structure and stability of a (4+0) parallel and a (3+1) hybrid G-quadruplex using over 60 modified sequences containing a single-position substitution of 2'-O-4'-C-methyl...

The aim of this study is to evaluate the blood level anti-heart antibodies (AHA) and its correlation with clinical outcomes in patients severe moderate coronavirus disease 2019 (COVID-19). included 34 (23 males; mean age 60.2 ± 16.6 years) COVID-19 pneumonia. Besides standard medical examination, AHA levels were observed, including antinuclear antibodies, antiendothelial cell anti-cardiomyocyte...

The development of antinuclear antibodies after long-term use of anti-TNF therapy has been reported by several authors. The occurrence of lymphoproliferative neoplasms and, less commonly, solid tumors has also been reported. We present a case of simultaneous development of antinuclear antibodies and solid tumor in a patient with spondyloarthritis while on infliximab therapy. The implications an...

The granulomatosis with polyangiitis (GPA), formerly known as Wegener’s granulomatosis, is a pauci-immune vasculitis involving small- and medium-sized blood vessels. Classically, the patients inflicted with this disease present with a triad of necrotizing granulomatous inflammation of the respiratory tract, cutaneous necrotizing vasculitis, and glomerulonephritis (GN). The antinuclear (ANA) and...

OBJECTIVE A human lymphoproliferative syndrome characterized by a defect of the Fas-mediated apoptosis pathway in the absence of a fas gene mutation (Autoimmune Lymphoproliferative Disease) has recently been described and characterized by autoimmune phenomena. The aim of this study was to investigate the presence of antinuclear and antiphospholipid antibodies and to define their specificity in ...

Sera can produce nuclear or perinuclear immunofluorescence staining in neutrophils which may be caused by antibodies with differing antigenic specificities. These include perinuclear antineutrophil cytoplasmic antibodies (P-ANCA), granulocyte specific antinuclear antibody (GS-ANA), and antinuclear antibody (ANA). There is controversy over the value of formalin fixation of neutrophils in differe...
