A new technology reveals that immune system genes switch on and off differently in women and men, and the source of that variation is not primarily in the DNA.A new technology for studying the human body’s vast system for toggling genes on and off reveals that genes associated with the immune system toggle more frequently, and those same genes operate differently in women and men. Some genes are virtually always on, like the clock light on a microwave; others sit unused for years at a time, like some regrettable appliance you bought, stuffed into the back of the closet and forgot. Some genes can be always on in one person and always off in another. A minority of genes switch on and off, like a favorite cell phone app. A new technology, which makes it possible to study the molecules that regulate all of that switching in living people as they go about their lives, has revealed some intriguing surprises, according to a study from the Stanford University School of Medicine.

Patients diagnosed with systemic sclerosis (SSc) may have a three times greater risk of venous thromboembolism (VTE) – including potentially deadly clots in the lungs – and an increased risk in the first year after a diagnosis, according to a large population database study from Canada. The study of 1,245 SSc patients (83% female, mean age 56 years old),and 12,670 matched controls in British Columbia (BC), attributes the increased risk to vascular damage from SSc-related fibrosis that causes endothelial dysfunction and hypercoagulability due to inflammation.

BACKGROUND. TGF-β has potent profibrotic activity in vitro and has long been implicated in systemic sclerosis (SSc), as expression of TGF-β–regulated genes is increased in the skin and lungs of patients with SSc. Therefore, inhibition of TGF-β may benefit these patients. METHODS. Patients with early, diffuse cutaneous SSc were enrolled in an open-label trial of fresolimumab, a high-affinity neutralizing antibody that targets all 3 TGF-β isoforms. Seven patients received two 1 mg/kg doses of fresolimumab, and eight patients received one 5 mg/kg dose of fresolimumab. Serial mid-forearm skin biopsies, performed before and after treatment, were analyzed for expression of the TGF-β–regulated biomarker genes thrombospondin-1 (THBS1) and cartilage oligomeric protein (COMP) and stained for myofibroblasts. Clinical skin disease was assessed using the modified Rodnan skin score (MRSS).

ROME (FRONTLINE MEDICAL NEWS) – Updated expert recommendations from the European League Against Rheumatism for the treatment of systemic sclerosis will focus on several new treatment options, although the use of biologic agents is not included in detail because there are still too few data on these drugs to give firm guidance on their use. The EULAR Scleroderma Trials and Research group (EUSTAR) recommendations for the treatment of scleroderma were first published 6 years ago ( Ann. Rheum. Dis. 2009;68:620-8 ) and considered data through December 2006. “Since then, a number of new drugs have become available and new and important information has been published concerning treatments already known before,” said Dr. Otylia Kowal-Bielecka of the Medical University of Bialystok, Poland, who discussed some of the main highlights of the revised recommendations (Ann. Rheum. Dis. 2015;74:90-1) at the European Congress of Rheumatology.

Patients with systemic sclerosis have a distinct colonic microbiome that might contribute to clinical manifestations of the disease, according to a new study. "I see scleroderma patients exclusively in my practice, and gastrointestinal symptoms are sometimes the number one complaint," said Elizabeth Volkmann, MD, from the University of California at Los Angeles. "Patients often don't even feel comfortable disclosing these symptoms because they are so personal."

In a recent study entitled “Scleroderma renal crisis,” the authors summarize the most recent findings related to scleroderma renal crisis, a serious but treatable complication of systemic sclerosis. The study was published in the journal Seminars in Arthritis and Rheumatism. Scleroderma (or systemic sclerosis) is an autoimmune disease characterized by skin thickening, a process known as fibrosis. Several complications associated with scleroderma are due to the fibrosis process that is actually not restricted to the skin, reaching in severe cases, internal organs such as kidneys.

Northwestern Medicine scientists have discovered that scar-forming cells in scleroderma come from fat tissue within layers of the skin, a new cellular origin that could be a key to developing treatments for the incurable disease in the future. Scleroderma, also called systemic sclerosis, is a rare autoimmune connective tissue disorder in which the skin thickens and hardens, forming scar-like buildup, a process called fibrosis. Until now, scientists have not known the mechanisms responsible for tissue fibrosis.

Radiologists are essential for diagnosis and further testing of pediatric patients with systemic sclerosis (SSc), according to a report published by researchers at the University of Washington Medical Center, Seattle. The paper, titled Multimodality Thoracic Imaging of Juvenile Systemic Sclerosis: Emphasis on Clinical Correlation and High-Resolution CT of Pulmonary Fibrosis, appeared in the February 2015 issue of the American Journal of Roentgenology. SSc is disease of the connective tissue that involves many different parts of the body. It is characterized by abnormal blood vessels (vasculopathy) and fibrosis — the thickening and scarring of connective tissue.
