Dr. Shiel received a Bachelor of Science degree with honors from the University of Notre Dame. There he was involved in research in radiation biology and received the Huisking Scholarship. After graduating from St. Louis University School of Medicine, he completed his Internal Medicine residency and Rheumatology fellowship at the University of California, Irvine. He is board-certified in Internal Medicine and Rheumatology.
Aggrecan is a type of protein known as a proteoglycan, which means it has several sugar molecules attached to it. It is the most abundant proteoglycan in cartilage, a tough, flexible tissue that makes up much of the skeleton during early development. Most cartilage is later converted to bone (a process called ossification), except for the cartilage that continues to cover and protect the ends of bones and is present in the nose, airways, and external ears. Aggrecan attaches to the other components of cartilage, organizing the network of molecules that gives cartilage its strength. These interactions occur at a specific region of the aggrecan protein called the C-type lectin domain (CLD). Because of the attached sugars, aggrecan attracts water molecules and gives cartilage its gel-like structure. This feature enables the cartilage to resist compression, protecting bones and joints. Although its role is unclear, aggrecan affects bone development.
A complex of genes on chromosome 6 that code for the antigens that determine tissue and blood compatibility. In humans, histocompatibility antigens are called human leukocyte antigens (HLA) because they were originally discovered in large numbers on lymphocytes. There are thousands of combinations of HLA antigens. Class I MHC antigens (HLA-A, HLA-B, and HLA-C) are found on all nucleated cells and platelets. Class II antigens (HLA-DR, HLA-DQ, and HLA-DP) are found on lymphocytes and antigen processing cells and are important in the specific immune response. In tissue and organ transplantation, the extent to which the HLA or “tissue type” of the donor and recipient match is a major determinant of the success of the transplant.
Lupus in children tends to be more aggressive than in adults, says Dr. Pascual. The exact reasons for this are not understood. One theory is that people are born with genetic susceptibility to the disease that may be triggered by environmental factors such as a virus. “Children with the condition may have inherited a more complex set of predisposing genes,” she says. But this theory has yet to be proved.
“I have given up sugar (except natural sugars), all soft drinks, pasta, chocolate, takeaways, and most processed foods/snacks. I have experienced a marked difference in energy levels and severity of flares, plus I have lost almost three stone in a year. I eat a simple diet, increase fruits/veg and I have found it has also helped with my stomach issues.”
The aim of this review is to provide an up-to-date overview of treatment approaches for systemic lupus erythematosus (SLE), highlighting the multiplicity and heterogeneity of clinical symptoms that underlie therapeutic decisions. Discussion will focus on the spectrum of currently available therapies, their mechanisms and associated side-effects. Finally, recent developments with biologic treatments including rituximab, epratuzumab, tumor necrosis factor (TNF) inhibitors, and belimumab, will be discussed.

Because the antibodies and accompanying cells of inflammation can affect tissues anywhere in the body, lupus has the potential to affect a variety of areas. Sometimes lupus can cause disease of the skin, heart, lungs, kidneys, joints, and/or nervous system. When only the skin is involved by rash, the condition is called lupus dermatitis or cutaneous lupus erythematosus. A form of lupus dermatitis that can be isolated to the skin, without internal disease, is called discoid lupus erythematosus. When internal organs are involved, the condition is referred to as systemic lupus erythematosus (SLE).
If this disorder is suspected in people, brain scans are usually required for early detection. These scans can show localized areas of the brain where blood supply has not been adequate. The treatment plan for these people requires anticoagulation. Often, low-dose aspirin is prescribed for this purpose, although for cases involving thrombosis anticoagulants such as warfarin are used.
We encourage you to reach out to friends, family, and join support groups to share your feelings and fears. Also, remember to be your own best advocate in your journey with lupus, take great notes, and bring a support person with you to each visit to help remind you of the doctor’s advice and information. We are always here for you, please join our online community and share your story or ask us any questions you may have! Back to top
The classical period began when the disease was first recognized in the Middle Ages. The term lupus is attributed to 12th-century Italian physician Rogerius Frugard, who used it to describe ulcerating sores on the legs of people. No formal treatment for the disease existed and the resources available to physicians to help people were limited.
If your doctor suspects you have lupus, he or she will focus on your RBC and WBC counts. Low RBC counts are frequently seen in autoimmune diseases like lupus. However, low RBC counts can also indicate blood loss, bone marrow failure, kidney disease, hemolysis (RBC destruction), leukemia, malnutrition, and more. Low WBC counts can point toward lupus as well as bone marrow failure and liver and spleen disease.
Lupus nephritis is one of the most common complications of lupus. (13) People with lupus nephritis are at a higher risk of developing end-stage renal disease, requiring dialysis or a transplant, says Kaplan. Symptoms of the condition include high blood pressure; swelling of the hands, arms, feet, legs, and area around the eyes; and changes in urination, such as noticing blood or foam in the urine, needing to go to the bathroom more frequently at night, or pain or trouble urinating.
Lupus is not necessarily life threatening when treated appropriately. Up to 90 percent of patients will have a normal life expectancy if they are followed closely by their doctor and receive proper treatment. (4,5) Lupus can, however, increase mortality rates because patients have a higher risk of heart disease, infection or complications such as inflammation of the kidney, or nephritis, says Francis Luk, MD, an assistant professor of rheumatology and immunology, Wake Forest Baptist Medical Center.

Decorin is a protein coded for by the DCN gene. This protein is a component of the extracellular matrix, which is the intricate lattice of proteins and other molecules that forms in the spaces between cells. Decorin is found in the extracellular matrix of a variety of connective tissues, including skin, tendon, bone, and cartilage. Connective tissues support the body’s joints and organs. Decorin is involved in the organization of proteins called collagens. Collagens strengthen and support connective tissues throughout the body. Collagens also play an important role in the cornea, which is the clear outer covering of the eye. Bundles of collagen called fibrils must be strictly organized for the cornea to be transparent. Decorin ensures that these collagen fibrils are uniformly sized and regularly spaced.
For instance, a dermatologist for cutaneous lupus (skin disease), a cardiologist for heart disease, a nephrologist for kidney disease, a neurologist for brain and nervous system disease, or a gastroenterologist for gastrointestinal tract disease. A woman with lupus who is considering a pregnancy needs an obstetrician who specializes in high-risk pregnancies.
