Anti-nuclear antibodies (ANA) are fundamental for the diagnosis of autoimmune diseases, and have been determined by indirect immunofluorescence assay (IIFA) decades. As demand ANA testing increased, alternative techniques were developed challenging classic IIFA. These platforms differ in their antigen profiles, sensitivity specificity, raising uncertainties regarding standardisation interpretation incongruent results. Therefore, an international group experts has created recommendations...
Abstract Antinuclear antibodies wer demonstrated in the sera of 43 45 (96%) patients with progressive systemic sclerosis (22 24 diffuse scleroderma and 21 CREST syndrome variant). This high percentage positive reactions resulted from use a tissue culture substrate (Hep‐2) to detect antinuclear by indirect immunofluorescent method. Patterns nuclear staining included fine speckles, large coarse nucleolar centromere staining. When organ sections such as mouse kidney were used for detection...
Systemic lupus erythematosus (SLE) is an autoimmune disease with marked gender and ethnic disparities. We report a large transancestral association study of SLE using Immunochip genotype data from 27,574 individuals European (EA), African (AA) Hispanic Amerindian (HA) ancestry. identify 58 distinct non-HLA regions in EA, 9 AA 16 HA (∼50% these have multiple independent associations); include 24 novel (P<5 × 10-8), refined signals established regions, extended associations to additional...

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with strong genetic component. We undertook the present work to perform first genome-wide association study on individuals from Americas who are enriched for Native American heritage.We analyzed 3,710 US and 4 countries of Latin America were diagnosed as having SLE, healthy controls. Samples genotyped HumanOmni1 BeadChip. Data out-of-study controls HumanOmni2.5 also included. Statistical analyses performed using SNPtest...
The International Consensus on ANA Patterns (ICAP) was initiated as a workshop aiming to thoroughly discuss and achieve consensus regarding the morphological patterns observed in indirect immunofluorescence assay HEp-2 cells. One of topics discussed at second ICAP workshop, addressed this paper, harmonization reporting test results. This discussion centered issue if cytoplasmic mitotic should be reported positive or negative. report outlines issues that impact two major different methods....
To develop response criteria for adult dermatomyositis (DM) and polymyositis (PM). Expert surveys, logistic regression, conjoint analysis were used to 287 definitions using core set measures. Myositis experts rated greater improvement among multiple pairwise scenarios in where different levels of 2 measures presented. The PAPRIKA (Potentially All Pairwise Rankings Possible Alternatives) method determined the relative weights definitions. performance characteristics evaluated on patient...
Systemic lupus erythematosus (SLE), a complex and heterogeneous autoimmune disease, represents significant challenge for both diagnosis treatment. Patients with SLE in Latin America face special problems that should be considered when therapeutic guidelines are developed. The objective of the study is to develop clinical practice American patients lupus. Two independent teams (rheumatologists experience management methodologists) had an initial meeting Panama City, Panama, April 2016. They...
The second meeting for the International Consensus on Antinuclear antibody (ANA) Pattern (ICAP) was held 22 September 2015, one day prior to opening of 12th Dresden Symposium Autoantibodies in Dresden, Germany. ultimate goal ICAP is promote harmonization and understanding autoantibody nomenclature, thereby optimizing ANA usage patient care. newly developed website www.ANApatterns.org introduced more than 50 participants. This followed by several presentations discussions focusing key issues...
The establishment of the International Consensus on ANA Patterns (ICAP) in 2014-2015 was welcomed by members medical community as a significant improvement guiding harmonization test interpretation and reporting. In subsequent years, several itinerant meetings continuous interaction with contributed to disseminate ICAP immunofluorescence patterns observed indirect assay HEp-2 cells (HEp-2 IFA) promote progressive classification IFA patterns. 6th Workshop held person September 6, 2021...
Vaccine hesitancy is considered a major barrier to achieving herd immunity against COVID-19. While multiple alternative and synergistic approaches including heterologous vaccination, booster doses, antiviral drugs have been developed, equitable vaccine uptake remains the foremost strategy manage pandemic. Although none of currently approved vaccines are live-attenuated, several reports disease flares, waning protection, acute-onset syndromes emerged as short-term adverse events after...
