Sule and Michelle Petri Summary There are interesting data on nutritional supplementation in the treatment of systemic lupus erythematous. However, at this time, there is little convincing human data to support dietary modifications or nutritional supplementation. The course can be quite variable, ranging from intermittent exacerbations to severe, life-threatening disease. Females are affected nine times more frequently than men, and disease preva- lence is higher in African Americans, Asians, and Hispanics. However, studies examining the role of dietary modification have shown some promise. These autoantibodies are deposited in the kidneys by 4 to 5 months of age, leading to nephritis and renal disease by 9 to10 months of age (1). Caloric restriction in this murine model has a profound effect on the onset and progression of nephritis and has been shown to improve survival (2). In B/W mice, the life span is increased from 345 days in controls to 494 days in caloric-restricted mice. The calorie restriction (40% less food) also significantly delays the onset of nephritis. By 14 months of age, 0% of the calorie-restricted mice develop nephritis, compared with 100% of the controls (3). However, in order to implement this calorie restriction in humans, 25 to 35% or more of total intake would have to be cut, beginning before adolescence and continuing for life. Low-Protein Diets High protein intakes have been associated with acceleration of kidney damage in both humans and experimental animals (7). In humans, protein restriction has long been a recommended treatment modality in patients with renal failure. Dietary Fat Intake Over the last 20 years, there have been numerous studies of fatty acids and their role in inflammation. Omega-3 (n-3) and omega-6 (n-6) fatty acids are considered essential fatty acids, which means that they are essential to human health but cannot be made in the body and must be obtained from food. Both types of fatty acids play a crucial role in brain function as well as normal growth and development (12,13). The n-3 fatty acids have anti- inflammatory, anti-arrhythmic, and anti-thrombotic properties (14). The n-3 polyunsaturated fatty acids are found in oily fish and vegetable sources such as the seeds of chia, perilla, flax, and walnuts. Fish-oil supplementation also improves survival in female mice and decreases proteinuria. The anti-inflammatory effects of fish oil seem to depend on the synergistic effects of at least two n-3 fatty acids. The 18 g of fish-oil supplement reduced triglycerides by 38%, very low-density lipoprotein cholesterol by 39% and increased high-density lipoprotein cholesterol by 28%. Twenty-six patients with lupus nephritis were given fish oil in a double-blind cross-over trial. Vitamin E Vitamin E, a fat-soluble vitamin, is an antioxidant vitamin involved in the metabolism of all cells. It protects essential fatty acids from oxidation and prevents breakdown of body tissues. A meta-analysis of 135,967 participants in 19 clinical trials identified a dose-dependent relationship between vitamin E and all-cause mortality. Selenium Selenium is a natural antioxidant associated with anti-inflammatory properties. Levels of blood glutathione-peroxidase increase after selenium and vitamin E supplementation. Signs of selenium toxicity include diarrhea, vomiting, hair and nail loss, and lesions of the central nervous system. It acts as a catalytic regulatory ion for enzymes, proteins, and transcription factors. As opposed to other dietary manipulations, zinc restriction was found to be beneficial both early (after weaning) and later in life (at 6 months of age). However, if the zinc deficiency was introduced later in life (at 10 weeks of age), it had little beneficial effect on disease progression (31). These data suggest that there is a critical period in which manipulation of dietary zinc can alter the course of autoimmune disease. In those who were compliant, serum creatinine during flaxseed administration declined from a mean of 0. Reported complications include diarrhea, infertility, and one reported case of death resulting from cardiac shock (35). Dehydroepiandrosterone Autoimmune diseases are more prevalent in women and immune responses may be influenced by sex hormones. Renal histopathology was more severe in iron-supplemented mice than in pair-fed control mice. Immunostaining with anti-IgG and anti-C3 in severely iron-deficient mice (fed 3 mg iron/kg, normal: 35 mg/kg) was more intense.
