Brief Summary

Omega-3 fatty acids have been considered anti-inflammatory lipids based on data from epidemiological studies of Greenland Eskimos whose diet is rich in fish, sources of polyunsaturated fatty acids. Fatty acids from the omega-3 family \[mainly the α-linolenic acid, eicosapentaenoic (EPA) and docosahexaenoic (DHA)\], as well as those of the omega-6 family \[represented mainly by linoleic acid and arachidonic acid (AA)\] are essential for the synthesis of eicosanoids, prostaglandins, leukotrienes, thromboxanes and other oxidative factors, major mediators and regulators of inflammation. Systemic lupus erythematosus (SLE) is an inflammatory autoimmune disease characterized by the loss of balance of cellular immunoregulation and increased levels of circulating inflammatory mediators.Thus, omega-3 supplementation could represent additional therapy for individuals with SLE. The aim of this study was to investigate the effects of omega-3 fatty acids on circulating levels of inflammatory and biochemical markers in women with SLE.

Outcome Measures

Primary Outcomes (3)

  • Variations of serum cytokines related to omega 3 treatment

    The primary outcomes was median (interquartile range, IQR) variations \[ΔV=pre-Treatment (T0) minus post-treatment (T1) concentrations\] of serum cytokines (IL6 e IL 10) after 12 weeks of treatment between groups.

    Cytokines measurement on T0 (baseline) and T1 (after 12 weeks)

  • Variations of serum adipokines related to omega 3 treatment

    The primary outcomes was median (interquartile range, IQR) variations \[ΔV=pre-Treatment (T0) minus post-treatment (T1) concentrations\] of serum adipokines (leptin and adiponectin) after 12 weeks of treatment between groups.

    Adipokines measurement on T0 (baseline) and T1 (after 12 weeks)

  • Variations of serum C reactive protein related to omega 3 treatment

    The primary outcomes was median (interquartile range, IQR) variations \[ΔV=pre-Treatment (T0) minus post-treatment (T1) concentrations\] of serum C reactive protein after 12 weeks of treatment between groups.

    C reactive protein measurement on T0 (baseline) and T1 (after 12 weeks)

Secondary Outcomes (1)

  • Variations of biochemical markers related to omega 3 treatment

    Biochemical markers measurement on T0 (baseline) and T1 (after 12 weeks)

Study Arms (2)

Hiomega-3 supplement

EXPERIMENTAL

Patients in the study group received, throughout 12 weeks, two tablets per day of omega-3 fatty acids (540mg of EPA and DHA of 100mg; Hiomega-3 supplement of Naturalis® company). Participants were seen at baseline (T0) and at week 12 (T1) for clinical, laboratory and nutritional assessment. Variables measured at each visit included: disease activity index, using the Systemic Lupus Disease Activity Index (SLEDAI-2k)16; damage index (Systemic Lupus International Collaboration Clinics/American College of Rheumatology damage index - SLICC/ACR)17; fasting lipid and glucose profile; standard laboratory tests to assess SLE ; cytokines (IL-6, IL-10), adipokines (leptin, adiponectin) C-reactive protein (CRP), nutritional assessment, and in use medications.

Dietary Supplement: Hiomega-3 supplement of Naturalis® company -

Control group

NO INTERVENTION

Patients in the control group did not receive the nutrient nor any kind of placebo. They were seen at baseline (T0) and at week 12 (T1) for clinical, laboratory and nutritional assessment. Variables measured at each visit included: disease activity index, using the Systemic Lupus Disease Activity Index (SLEDAI-2k)16; damage index (Systemic Lupus International Collaboration Clinics/American College of Rheumatology damage index - SLICC/ACR)17; fasting lipid and glucose profile; standard laboratory tests to assess SLE ; cytokines (IL-6, IL-10), adipokines (leptin, adiponectin) C-reactive protein (CRP), nutritional assessment, and in use medications.

Interventions

Patients (N=22) were seen at baseline (T0) and at week 12 (T1) for clinical, laboratory and nutritional assessment, and were contacted by telephone in week 6 to check on compliance and any adverse events. Patients received, throughout 12 weeks, two tablets per day of omega-3 fatty acids (540mg of EPA and DHA of 100mg; Hiomega-3 supplement of Naturalis® company - registered in the National Health Department number 4.1480.0006.001-4). All participants were instructed not to take omega-3 rich foods during the study period.
