Higher cholesterol linked to lower risk of scleroderma in South Korean study by Margarida Maia, PhD | January 2, 2024 People with more circulating cholesterol — a type of lipid (fat) that plays an important role in the body — may be at a lower risk of developing systemic sclerosis (SSc), according to a study of nearly 10 million people living in South Korea.
Based on these findings, researchers suggest that a person’s lipid levels, which can be profiled from a blood test, may tell how likely that person is to develop SSc, which could help in early diagnosis. The study, “Association Between Lipid Profile and Risk of Incident Systemic Sclerosis: A Nationwide Population-Based Study,” was published in the journal Clinical Epidemiology.

Scleroderma is a chronic disease that affects the skin and connective tissue, the tissue that supports and holds organs together, and is also found in the joints.
The hallmark of scleroderma is thick and hardened skin caused by excessive production of collagen, a protein that is the main component of scar tissue. This scar tissue can accumulate in and damage organs, including the heart and blood vessels, and the lungs, stomach, and kidneys. Females are about four times more likely to develop scleroderma than males. Disease onset typically occurs between ages 35 and 50, though people of all ages can be affected. Causes Scleroderma is an autoimmune disease, meaning it is caused by an overactive immune system that mistakenly attacks the body’s own tissues. The resulting excessive inflammation damages the skin and affected organs. It is a complex condition, and the underlying disease process is not well understood. It is thought that the disease results from a combination of genetic and environmental factors. Scleroderma is not contagious, infectious, or cancerous. Symptoms Symptoms of scleroderma vary among patients, and can range from very mild to life-threatening depending on which parts of the body are affected and the extent of organ involvement. A mild case can become serious if not treated properly. Characteristic symptoms, besides patches of thick and hardened skin, include contractures when skin stiffens over joints, skin ulcers (sores), calcinosis — when lumps of calcium form under the skin — and Raynaud’s phenomenon, in which the fingers and toes feel numb, prickly, or frigid in response to cold temperatures or emotional distress. Manifestations affecting internal organs include damage to muscle and bone tissue, shortness of breath, an abnormal heart rhythm, a burning sensation in the chest (heartburn), difficulty swallowing, blurred vision. A scleroderma renal crisis is possible in some systemic scleroderma (mentioned below) patients. This renal, or kidney, crisis is a serious disorder characterized by a sudden onset of high blood pressure, progressive kidney failure, hypertensive encephalopathy (brain dysfunction or damage due to high blood pressure), and/or microangiopathic hemolytic anemia, or anemia due to the red blood cells being sheared (ripped apart) as they pass through small blood vessels. Raynaud's phenomenon is a common systemic sclerosis symptom by Steve Bryson, PhD Elevated activity of a blood-clotting protein called Factor XIII (FXIII) in the bloodstream of adults with systemic sclerosis (SSc) is tied to the presence of Raynaud’s phenomenon, a common SSc symptom, a small study suggests.
While most study participants had FXIII activity levels within the normal range, “patients with higher FXIII activity are more likely to have circulatory disorders in their hands,” the researchers noted. The study, “Factor XIII and Endothelial Dysfunction in Patients with Systemic Sclerosis,” was published in the journal Hämostaseologie. In survey, caregivers highlight key barriers to diagnosis, treatment by Steve Bryson, PhD Caregivers of children with juvenile scleroderma cited a lack of knowledge about the rare disease within the medical community as the primary barrier to a proper diagnosis and treatment, according to a new survey study.
For more than a quarter of the children, it took more than a year from the first symptoms to get a correct diagnosis. Misdiagnoses — ranging from allergies to eczema to a congenital overgrowth disorder — were commonly reported. Other major hurdles reported by almost all respondents included finding reliable information about scleroderma — especially regarding pediatric patients — juggling work and the child’s healthcare needs, side effects of medications, and balancing care and school. “Identifying key care barriers will help direct efforts to address needs, reduce disparities in care, and improve patient outcomes,” the researchers wrote, noting that delays in diagnosis and treatment “have been associated with more persistent disease activity, higher damage scores, and higher relapse rates.” The survey study, “Barriers to care in juvenile localized and systemic scleroderma: an exploratory survey study of caregivers’ perspectives,” was published in the journal Pediatric Rheumatology. Wrong diagnosis common for many children with scleroderma Juvenile scleroderma is a rare type of childhood scleroderma. Most cases are characterized by localized hardened patches of skin, particularly on the arms, legs, or trunk (torso). In more severe cases, the disease can affect organs throughout the body — this is known as systemic scleroderma — including the heart, kidneys, and blood vessels. In some children, these symptoms can be life-threatening. Late diagnoses are common, with reported wait times of up to three years. Resulting delays in treatment have been linked to more and lasting disease activity, more tissue and organ damage, and more relapses. The objective of this study, conducted as an online survey, was to investigate the obstacles caregivers encounter when attempting to access specialized care and treatment for children with juvenile scleroderma. “This information could then guide future efforts to develop effective interventions to reduce diagnostic and treatment delays,” the researchers noted. Study targets correlations among SSc patients with different types of lung disease by Andrea Lobo, PhD The degree of skin tightening is associated with changed levels of proteins implicated in inflammation and cell death among systemic sclerosis (SSc) patients with pulmonary involvement, a study in India reports.
The study established protein correlations among SSc patients with different types of lung disease, which might contribute to identifying lung involvement in people with newly diagnosed SSc, the team suggested. “A longitudinal follow up in these patients with assessment of these immunological parameters may be helpful in monitoring the disease,” the researchers wrote. The study, “A comparative study of modulatory interaction between cytokines and apoptotic proteins among Scleroderma patients with and without pulmonary involvement,” was published in the journal Cytokine. SSc is characterized by abnormal scarring of the skin and potentially internal organs, such as the heart, kidney, lungs, and digestive tract. The disease is thought to develop from the combination of immune dysfunction — meaning the activation and recruitment of immune cells and the production of self-targeting antibodies (fibrosis) — and damage to small blood vessels. The most prominent forms of lung involvement in SSc are interstitial lung disease (ILD), a group of conditions characterized by lung inflammation and fibrosis, and pulmonary arterial hypertension (PAH), caused by the narrowing of small blood vessels that transport blood to the lungs. Studies have reported the involvement of proinflammatory and pro-fibrotic signaling molecules called cytokines in SSc. Also implicated in the disease are proteins associated with apoptosis — programmed cell death (as opposed to cell death caused by injury), which can alter immune responses. To investigate the possible correlation between blood cytokines and apoptotic proteins in SSc, researchers in India analyzed 100 treatment-naïve SSc patients, with or without pulmonary involvement, as well as 100 healthy people who served as controls. Levels may serve as biomarkers for the disease, help predict outcomes by Steve Bryson, PhD Levels of microparticles, tiny molecule-filled sacs shed from cells, were altered in the bloodstream of adults with systemic sclerosis (SSc), a study reports.
Elevated microparticles derived from blood-clotting platelets were associated with disease-related antibodies and longer disease duration. By contrast, lower levels of microparticles shed from endothelial cells that line blood vessels were tied to worse skin and blood vessel involvement. These results suggest microparticles may participate in developing SSc and serve as biomarkers to predict outcomes, the researchers noted in “Microparticles: potential new contributors to the pathogenesis of systemic sclerosis?” which was published in Advances in Rheumatology. SSc, also called scleroderma, is an autoimmune disease that may affect multiple systems in the body. It’s marked by scar tissue building up in the skin and/or several organs, such as the heart, lungs, kidney, and digestive tract. Microparticles (MPs), or microvesicles, are tiny membrane-bound sacs shed from cells undergoing activation or apoptosis (programmed cell death), which contain cell type-specific components. Mostly shed from platelets, white blood cells, and endothelial cells, MPs have been shown to modulate inflammatory and blood clotting activities. Studies have suggested that people with SSc have higher levels of MPs in their blood, particularly those derived from endothelial cells (EMPs) and platelets (PMPs). A columnist praises her husband's approach to being a spouse caregiver by Lisa Weber We toasted to 18 years as a married couple while looking out over Tampa Bay, Florida. My amazing husband, Ross, had planned out every detail, from the surprise dinner reservations in the city to the romantic sunset-watching at the park. If you know me, you know pulling off a surprise is nearly impossible. Ross endured a week of grilling questions and still kept the itinerary under lock and key.
Although it was a beautiful night, we had to accommodate my blue-toned hands, a result of Raynaud’s, and sit indoors. But we moved forward with the evening and didn’t pay my disease much attention. And even when my gastroparesis limited my options on the menu, we chose to ignore it for the night and focus only on the happy memories we’ve built together. I even drank wine without worrying about the insufferable inflammation it would cause the next day. Because every now and then, it helps to take a vacation day from scleroderma. Study to focus on how immune system responses drive rare disease by Lindsey Shapiro, PhD The National Scleroderma Foundation has awarded a $200,000 research grant to a University of Minnesota scientist to study how immune system responses drive the emergence of scleroderma — the cause of which remains unknown. The funding for researcher Rafael Contreras-Galindo, PhD, comes in the form of the two-year Marta Marx Fund for the Eradication of Scleroderma Award, given to scientists submitting the second-highest scoring research proposal to the foundation each year. The project will be titled, “Centromeres, Chromosome Instability and cGAS-STING Activation in Scleroderma Fibrosis.” “Identifying the cause of scleroderma is the main goal of this study,” Contreras-Galindo, assistant professor at the University of Minnesota’s The Hormel Institute, said in a university press release. Scleroderma is an autoimmune disease that arises when the body’s immune system becomes overactive and attacks its own tissues, in this case, causing inflammation and damage to connective tissue. In response, the cells overproduce collagen — a connective tissue protein — leading to scar tissue buildup that hardens and tightens connective tissues in the skin or other organs. While the results are known, the mechanisms underlying this process haven’t been fully worked out. Contreras-Galindo’s team will specifically examine the potential role of centromere dysfunction in triggering these harmful immune responses. Chromosomes, thread-like structures where DNA is packaged, consist of two identical halves. When a cell divides and replicates, these two halves split apart, ensuring that each new cell has the same genetic information as its parent. Centromeres sit between these two halves, holding them together and facilitating their split during cell division. If that process is defective, chromosomes become unstable and certain immune pathways can be triggered in response. With his team, Contreras-Galindo found that people with scleroderma had signs of centromere defects in their skin cells not seen in healthy people. Findings from their work were published in a study in the journal Nature Communications Data also indicated that an immune pathway called cGAS-STING was activated in SSc cells, which the researchers believe was triggered by the chromosomal abnormalities that were found. Joint pain common in pediatric scleroderma patients, lung disease in older ones by Lindsey Shapiro, PhD The clinical presentation of systemic sclerosis (SSc) differs significantly between adult and pediatric patients, according to a recent study in Turkey.
Particularly, adults were more likely to have lung disease and to be at a higher risk of death than children, who were more likely to experience joint inflammation and pain. These differences, in turn, influenced treatment choices, which diverged significantly between adults and children. The study, “Juvenile and adult-onset scleroderma: Different clinical phenotypes,” was published in the journal Seminars in Arthritis and Rheumatism. Dr. Lee Shapiro, CMO of the Steffens Scleroderma Foundation, shares his insight by Amy Gietzen of Scleroderma News In 2018, I was asked to be a keynote speaker at an interprofessional education event (IPE) that aimed to educate graduate students in various healthcare disciplines about scleroderma. I’m a patient advocate who’s lived with the disease for more than two decades, and I pride myself on spreading awareness and educating the public, so I gladly accepted. The event was sponsored in part by the Steffens Scleroderma Foundation, a nonprofit whose mission is to support research toward the treatment and cure of scleroderma and to promote greater understanding of the disease, especially among healthcare professionals. It’s also where I met Dr. Lee Shapiro, a prominent rheumatologist and the foundation’s chief medical officer. I’ve long admired Shapiro’s passion and dedication to the scleroderma community, so I recently reached out to him via email for an interview. Excerpts of our conversation follow, with light editing for clarity. Dr. Lee Shapiro, chief medical officer and founder of the Steffens Scleroderma Foundation. (Courtesy of Lee Shapiro)
