Management of Fatigue in Antiphospholipid Syndrome

Assessment of Fatigue

The American Gastroenterological Association and the European Crohn's and Colitis Organisation recommend using validated fatigue assessment tools, such as Visual Analogue Scale (VAS) or multidimensional fatigue inventories, to quantify fatigue severity in patients with chronic conditions, and evaluating the impact of fatigue on daily activities and quality of life 1, 2

The American College of Rheumatology suggests evaluating disease activity, anemia, vitamin deficiencies (including vitamin D), thyroid dysfunction, sleep disturbances, psychological factors, and medication side effects as potential contributing factors to fatigue in APS patients 2
Vitamin D deficiency is commonly defined as 25(OH)D levels ≤50 nmol/L (≤20 ng/mL), and vitamin D insufficiency is often defined as 25(OH)D levels between 50-75 nmol/L (20-30 ng/mL), as defined by the Endocrine Society 3
Risk factors for vitamin D deficiency include decreased dietary vitamin D intake or absorption, limited sun exposure or darker skin pigmentation, older age, inflammatory bowel disease, malabsorptive conditions, or history of gastric bypass, being homebound or institutionalized, and obesity, as noted by the American College of Physicians 3

Graded exercise therapy has been shown to be beneficial in chronic fatigue, according to the National Institute of Neurological Disorders and Stroke 4
Energy conservation strategies, such as pacing activities, prioritizing tasks, and scheduling rest periods, can help manage fatigue, as recommended by the British Society of Gastroenterology 5
Cognitive behavioral therapy can be an effective coping strategy for patients with chronic fatigue, as suggested by the American Psychological Association 2
For patients with established vitamin D deficiency and fatigue symptoms, a trial of vitamin D supplementation is reasonable, as suggested by the European Society for Clinical Nutrition and Metabolism 6

The American College of Cardiology recommends treating comorbid conditions, such as depression and anxiety, to help manage fatigue in APS patients 2
Patients with inflammatory bowel disease should be specifically evaluated for vitamin D deficiency when presenting with fatigue, as recommended by the European Crohn’s and Colitis Organisation 1

Patient education on the relationship between APS and fatigue can help patients develop appropriate expectations and coping strategies, as recommended by the Antiphospholipid Syndrome Foundation 2

Overlooking the psychological impact of fatigue can lead to social isolation and psychological distress, highlighting the need for specific interventions, as noted by the British Society of Gastroenterology 5
Excessive exercise can worsen fatigue, and graded approaches are preferred, according to the National Institute of Neurological Disorders and Stroke 4
Check for concurrent magnesium deficiency, especially in patients with malabsorption or gastrointestinal disorders, as magnesium is needed for vitamin D metabolism, as noted by the American Gastroenterological Association 1
Assess for other potential causes of fatigue, including anemia or iron deficiency, thyroid dysfunction, sleep disorders, and other nutrient deficiencies (B12, folate), as recommended by the American College of Gastroenterology 1
Recheck vitamin D levels after 3 months of supplementation, and assess improvement in fatigue symptoms using standardized scales when possible, as suggested by the Royal Osteoporosis Society 7
