(Reuters Health)—Women with osteoporosis who take bisphosphonates to help avoid fractures still need to have their bone density monitored, a Canadian study suggests. Researchers who studied more than 6,600 women taking osteoporosis drugs found that for nearly one in five, bone mineral density at the hip actually decreased after the women started taking the medication….

How HLA-B27 Research Landmarks, Advances Relate to Ankylosing Spondylitis Pathogenesis
The mechanistic link between human leukocyte antigen B27 (HLA-B27) and ankylosing spondylitis (AS) is one of the great enigmas in rheumatology. The introduction of biological therapies that target tumor necrosis factor (TNF) or the interleukin (IL) 23/IL-17A axis has had a major impact on the quality of life for many patients with AS, and one…
Treatments for Scleroderma with Gastrointestinal Involvement Address Symptoms
CHICAGO—Nine out of 10 scleroderma cases include clinical signs of gastrointestinal (GI) involvement, with severe involvement associated with high mortality rates, but the pathology of this is not very well understood, a GI expert said at the ACR’s State-of-the-Art Clinical Symposium. That has left clinicians with a slate of treatments—anti-reflux, antimicrobials and prokinetics—that address only…
Biomarkers Differentiate Crohn’s Disease from Ulcerative Colitis
NEW YORK (Reuters Health)—Newly identified biomarkers could aid in the diagnosis of inflammatory bowel disease (IBD) and help guide therapy, Canada-based researchers report. Accurately differentiating between Crohn’s disease (CD) and ulcerative colitis (UC) is important for ensuring early and appropriate treatment. However, the conditions can’t be reliably distinguished based on clinical symptoms, site of disease,…
Researchers Find the Switch that Underlies Macrophage Metabolism
During pro-inflammatory stimulation, a recent study found HIF1α—not Myc—is required for the regulation of glycolysis in macrophages. Researchers examined macrophages and the distinct transcriptional programs engaged in response to mitogenic and pro-inflammatory stimulation…
Route of Iron Replacement Doesn’t Impact IBD Activity, Quality of Life
NEW YORK (Reuters Health)—The route of iron replacement therapy alters the gut microbiome and metabolomics in patients with inflammatory bowel disease (IBD), but the route is unrelated to disease activity and quality of life, according to a new study. “Crohn’s disease patients are extremely fragile to disturbances and one might speculate about consequences in long-term…
Fungal Microbiota Dysbiosis Seen in Inflammatory Bowel Disease
NEW YORK (Reuters Health)—Patients with inflammatory bowel disease (IBD) show imbalance in their fungal intestinal microbiota, according to new findings. “The fungal microbiota is a new actor to take into account in the pathogenesis of IBD and potentially in other diseases,” Dr. Harry Sokol of Hospital Saint-Antoine in Paris, an author of the new study,…
ACPA-Positive & ACPA-Negative Patients with RA: The Difference Begins in the Lungs
A new study from Stockholm, Sweden, strengthens the link between the lungs and anti-citrullinated protein antibody (ACPA)–positive RA. After analyzing the bronchial tissue of untreated patients with early RA, researchers found the patients’ lungs had signs of immune cell accumulation and activation…
Air Pollution: Is There an Association with Rheumatic Disease?
Interactions between an individual’s genetic background and their exposure to environmental factors are thought to result in a cascade of immune reactions, ultimately leading to the development of autoimmune diseases such as rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), systemic lupus erythematosus (SLE) and juvenile dermatomyositis.1,2 For example, an environmental factor that conclusively affects susceptibility…
Rheumatologist Steven S. Overman Reflects on His Last Day of Practice, Future of Specialty
I am a few weeks post-retirement. Having written thank you notes and completed urgent home projects, I swing in a hammock at our currently fire-threatened cabin north of Winthrop, Wash., and reflect. I feel like a young boy while freely flipping pages of a hand-scribed picture book, The Principles of Uncertainty, by Maira Kalman. She…
