Expert Review of Clinical Immunology
|May 3, 2013
Summary
Vitamin D deficiency is common in systemic lupus erythematosus (SLE) and linked to increased disease activity and complications. Supplementation may help manage SLE, but more research is needed.
Area of Science:
- Immunology
- Endocrinology
- Rheumatology
Background:
- Vitamin D is a steroid hormone with critical roles in immune system regulation.
- Systemic lupus erythematosus (SLE) involves immune system dysregulation.
- Low vitamin D levels (hypovitaminosis D) are prevalent in SLE patients due to various factors.
Purpose of the Study:
- To review current evidence on the association between vitamin D status and SLE.
- To explore the impact of vitamin D on SLE onset, activity, and complications.
- To summarize recommendations for vitamin D supplementation in SLE.
Main Methods:
- Literature review of recent studies on vitamin D and SLE.
- Analysis of the relationship between vitamin D levels and disease parameters.
- Synthesis of current guidelines for vitamin D management in SLE.
Main Results:
- Hypovitaminosis D is frequent in SLE patients, influenced by lifestyle and medications.
- Low vitamin D levels correlate with higher SLE disease activity.
- Vitamin D deficiency is associated with increased risks of osteoporosis, fatigue, and cardiovascular issues in SLE.
Conclusions:
- Vitamin D plays a significant role in the immune system and SLE pathophysiology.
- Maintaining adequate vitamin D levels is important for managing SLE.
- Further research and clear guidelines are needed for optimal vitamin D supplementation in SLE patients.

01:22Connective Tissue Cell Types
Connective tissue develops from the mesoderm of a developing embryo and consists of cells, fibers, and ground substance: a gel-like material containing large complexes of carbohydrates and proteins. Connective tissue was first identified as a separate tissue family in the 18th century, and Johannes Peter Muller coined the term connective tissue.
Fat cells (adipocytes), smooth muscle cells (myoblasts), and bone cells (osteoblasts) are some connective tissue cell types. Some immune system cells...

01:19Multiple Sclerosis l: Introduction
Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
01:23Role of Skin in Vitamin D Synthesis
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).

01:26Nephrotic Syndrome II : Assessment and Medical Management
IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document any history...
01:29Autoimmune Disorders
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

01:24Nephrotic Syndrome I : Introduction
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of fluid...
