Serum samples from 539 subjects were screened for the presence of the anticentromere antibody on a human laryngeal carcinoma (HEp-2) cell line (Antibodies, Inc.). The antibody was present in 61 patients (11%), most of whom had features of limited scleroderma or the CREST syndrome (calcinosis cutis, Raynaud's phenomenon, esophageal dysfunction, sclerodactyly, and telangiectasia), either independently or in association with primary biliary cirrhosis. The antibody was rarely found in patients with rapidly advancing or diffuse scleroderma. The anticentromere antibody is therefore a useful prognostic indicator in patients with early scleroderma, as it may help to predict what pattern of scleroderma will evolve. Screening for this antibody should be conducted in all patients with Raynaud's phenomenon, primary biliary cirrhosis, and scleroderma. Other previous studies have indicated a similar disease specificity and prognostic importance of this antibody.

Anti-Centromere Protein A Antibody Disrupts the Competence of Mouse Oocytes Matured In Vitro.

Introduction: Anticentromere autoantibodies are associated with refractory IVF/ET failure, but causality is unclear. Experimental models are needed.
Methods: Immature oocytes collected from 23-day-old mice were matured in vitro for 18 h in a culture medium containing an anti-human centromere protein A (CENP-A) polyclonal antibody, and those oocytes' maturity and chromosome/spindle structure were assessed.

Objectives: Anticentromere antibodies (ACA) are typically found in limited cutaneous systemic sclerosis (lcSSc), whereas patients with anti-topoisomerase I antibodies (ATA) usually exhibit diffuse cutaneous involvement (dcSSc). We aimed to investigate the clinical phenotype and outcome of ACA-dcSSc.
Methods: A systematic literature review was conducted (January 1970 to April 2023) across MEDLINE, Scopus and OVID, to define whether SSc patients (population) within the ACA-dcSSc subset (exposure) had higher/lower risk for major organ involvement (interstitial lung disease-ILD, pulmonary hypertension-PH, primary myocardial involvement-PMI, scleroderma renal crisis-SRC) and mortality (outcomes) compared to ACA-lcSSc and ATA-dcSSc.
Impact of Season, Environmental Temperature, and Humidity on Raynaud Phenomenon in an Australian Systemic Sclerosis Cohort.

Article Synopsis
- - The study investigated how season, temperature, and humidity affect the severity of Raynaud phenomenon (RP) in patients with systemic sclerosis, utilizing data from the Australian Scleroderma Cohort Study.
- - Among 1,972 participants, 26.7% experienced worsened RP related to environmental factors such as low temperatures and high humidity, which were linked to poorer health-related quality of life.
- - The findings suggest that managing RP may benefit from maintaining warmer and drier conditions, highlighting the importance of environmental factors in treating this condition.

Article Synopsis
- - Gastrointestinal complications are common in systemic sclerosis (SSc) and may be linked to autoimmune factors and blood vessel damage, but the exact causes are unclear.
- - The study examined the small blood vessels in the abdomen of SSc patients using Doppler Ultrasound to explore their relationship with GI symptoms and disease progression.
- - Results showed differences in blood flow measurements between types of SSc and found significant correlations between blood vessel function and GI symptoms like fecal incontinence.
Autoantibodies in systemic sclerosis overlap syndrome and their correlation with organ damage and survival.

Article Synopsis
- Systemic sclerosis (SSc) can happen alongside other autoimmune diseases, creating a mix called SSc overlap syndrome (SSc OS). Scientists looked at how certain antibodies in the blood relate to the disease and patients' health.
- In a study with 141 patients, they found that the most common antibody was anti-Ro-52, relating it to different organ damages and health issues in SSc OS.
- They discovered that problems like kidney crises and high blood pressure in the lungs are serious risks that can affect survival for these patients.
