(Press-News.org) The American College of Rheumatology (ACR) has issued newly created guidelines for the screening, treatment, and management of lupus nephritis—a severe manifestation of systemic lupus erythematosus (SLE) where the disease attacks the kidneys. Previously, only general guidelines for SLE existed for clinicians. The guidelines, available today in Arthritis Care & Research, are specific to lupus nephritis and include methods for identifying renal disease, newer therapies, and treatment of pregnant SLE patients with kidney involvement.
The ACR estimates that up to 322,000 adult Americans are diagnosed with SLE, a chronic autoimmune disease that causes inflammation, fatigue, joint pain, and organ damage. Lupus nephritis is one of the most serious complications of SLE where inflammation of the kidney could lead to renal failure. Medical evidence suggests that 35% of adults in the U.S. have evidence of nephritis at the time of SLE diagnosis, and up to 60% develop kidney involvement during the first 10 years with the disease.
Furthermore, previous studies report that patient survival is reduced to 88% at 10 years when lupus nephritis is present, and that survival rate is even lower for African Americans. "Lupus nephritis can be life-threatening, and proper management of the disease is vital to prevent permanent organ damage and preserve quality of life for patients," explains one of the lead guideline contributors, Dr. Bevra Hahn, Professor of Medicine at the University of California, Los Angeles (UCLA). "Given the serious threat of kidney involvement in SLE and the availability of newer therapies, it was necessary to create specific guidelines for managing the care of patients with lupus nephritis."
To establish the 2012 lupus nephritis guidelines, investigators reviewed medical literature from 1966 through 2010 for all evidence pertaining to "lupus kidney disease." Three panels of researchers were involved with reviewing the data and producing the recommendations that include:
Advising renal biopsy (in previously untreated patients with active nephritis)
Adjunctive treatment (background therapy with hydroxychloroquine, ACE inhibitors, control of blood pressure to goal of 130/80 or lower for almost all SLE patients with nephritis)
Induction of improvement in patients
with ISN Class III/IV lupus glomerulonephritis
with Class IV or IV/V plus cellular crescents
with Class V "pure membranous" lupus nephritis
Maintaining improvement in patients responsive to induction therapy (with azathioprine or mycophenolate mofetil)
Changing therapies in patients not adequately responsive to induction therapy
Identifying vascular disease in SLE patients with renal abnormalities
Treating nephritis in pregnant patients
Despite the availability of new therapeutics, studies have shown an increase in the incidence of end-stage renal disease from lupus over the past twenty years, with specific increases in young patients, African Americans, and in the southern U.S. "We look forward to seeing a reduction in these trends with implementation of these guidelines as part of high-quality, comprehensive care for SLE patients," said Dr. Hahn.
The authors acknowledge that the guidelines are limited by the absence of agreed terms for remission, flare and response, and limited data to inform recommendations for steroid dosing and tapering of immunosuppressive therapies. Dr. Hahn concludes, "Ongoing evaluation and expansion of the guidelines is necessary to further improve outcomes for patients with SLE and nephritis."

STANFORD, Calif. — The common occurrence of blond hair among the dark-skinned indigenous people of the Solomon Islands is due to a homegrown genetic variant distinct from the gene that leads to blond hair in Europeans, according to a new study from the Stanford University School of Medicine.
"This is one of the most beautiful examples to date of the mapping of a simple genetic trait in humans," said David Reich, PhD, a professor of genetics at Harvard University, who was not involved in the study.
The study identifying the gene responsible for blond hair in the Solomon ...
A new study helps to resolve an ongoing controversy about whether Langerhans cells (LCs) in human skin function to suppress the immune response and promote tolerance to normal human skin and its "friendly" microbial flora or mobilize a lethal attack against harmful foreign invaders. The research, published online May 3rd in the journal Immunity by Cell Press, reveals that, depending on the situation, these versatile immune cells can perform either function.
Adult human skin contains billions of resident immune cells called T cells that provide protection from invading ...
Treatment guidelines updated for aneurysmal subarachnoid hemorrhage Patients who are diagnosed in the emergency room with a specific type of brain bleed should be considered for immediate transfer to a hospital that treats at least 35 cases a year, according to a new scientific statement from the American Heart Association/American Stroke Association.
The Guidelines for the Management of Aneurysmal Subarachnoid Hemorrhage (aSAH) is published online in Stroke, an American Heart Association Journal. It updates guidelines issued in 2009.

When eating is motivated by pleasure, rather than hunger, endogenous rewarding chemical signals are activated which can lead to overeating, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). The phenomenon ultimately affects body mass and may be a factor in the continuing rise of obesity.
"'Hedonic hunger' refers to the desire to eat for pleasure, and to enjoy the taste, rather than to restore the body's energy needs,"says Palmiero Monteleone, MD, of the University of Naples SUN in Italy ...
Women who smoke and carry specific variations in the genes that impact their metabolism are at higher risk of developing hot flashes in comparison with smokers who do not carry these gene variants, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology and Metabolism (JCEM).
Previous studies have shown that smoking is associated with earlier onset of menopause, increased odds of hot flashes and risk of postmenopausal osteoporosis. The current study aimed to explore which smokers have the highest risk of hot flashes ...
American and Spanish researchers have found potential ways for doctors to improve the treatment of hormone receptor-positive breast cancer even if they lack access to costly multi-gene tests, as they report at the 4th IMPAKT Breast Cancer Conference.
Because breast cancer is a biologically and clinically varied disease, doctors aim to choose appropriate treatments based on the characteristics of each patient's individual tumor. In the past, this has been done using pathology-based biomarkers; however these do not capture the full diversity of cancers.
"In this context, ...
Tubal ectopic pregnancy (TEP) is currently the leading cause of pregnancy-related deaths during the first trimester and a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM) shows that the hormone adrenomedullin (ADM) may help predict this condition.
TEP is a condition where the fertilized egg implants in the fallopian tubes instead of in the uterus. In pregnant women, cilia (small protuberances) pulsate, or beat, to propel an embryo through the fallopian tubes towards the uterus. Defects in ciliary beats ...
New findings presented at Europe's leading breast cancer translational research conference this year shed new light on the many biological differences between individual breast cancers.
Focused on the biological features that make tumors more or less sensitive to important therapies, the new studies will help doctors make crucial choices about the most appropriate treatment for millions of patients.
"Despite major advances in the treatment of breast cancer many patients continue to relapse and die from the disease," noted Prof Mitch Dowsett from the Royal Marsden Hospital, ...
A new analysis may help doctors identify breast cancer patients who will benefit from treatment with the immune suppressant drug everolimus, say French researchers at the 4th IMPAKT Breast Cancer Conference in Brussels, Belgium.
Everolimus is currently used as an immunosuppressant to prevent patients rejecting transplanted organs and in the treatment of renal cell cancer. Research is also being conducted into the drug's use in other cancers, including breast cancer.
Dr Thomas Bachelot, from Centre Leon Berard in Lyon and colleagues analyzed data from the TAMRAD study, ...
Breast cancer patients whose tumors express high levels of genes related to immune response are more likely to have their tumor completely eradicated by pre-operative chemotherapy compared to patients with low expression of these genes, Belgian researchers report at the 4th IMPAKT Breast Cancer Conference in Brussels, Belgium.
Their research has identified a group of patients who might be good candidates for treatments with new immune-targeting therapies.
Dr Michail Ignatiadis from Institut Jules Bordet, Brussels, and colleagues analyzed gene expression data from eight ...
