Impact of Ramadan diurnal intermittent fasting on rheumatic diseases.
Clinical Rheumatology 2020 August
INTRODUCTION: Ramadan intermittent fasting is observed by Muslims from sunrise to sunset and alternated with moments of re-feeding. The aims of this study were to assess the impact of Ramadan fasting on rheumatoid arthritis (RA) and spondyloarthritis (SpA) activity and to assess its impact on chronic medications intake in patients with rheumatic diseases.
METHODS: This prospective monocentric study included patients with RA or SpA who fasted during Ramadan of 2019. The disease activity and the managing of chronic medications were assessed and compared between two visits: the first one 6 months before starting Ramadan fasting and the second after fasting at least 7 days.
RESULTS: Fifty-six patients were included: 36 with RA (average age 57.5 ± 10.9 years) and 20 with SpA (average age 47 ± 12.6 years). In the RA group, the Disease Activity Scores (DAS) 28 ESR, and DAS 28 CRP decreased after fasting respectively from 4.3 ± 1.3 to 3.5 ± 1.4 (p < 0.001) and from 3.4 ± 1.2 to 2.9 ± 1.3 (p = 0.001). In the SpA group, Ankylosing Spondylitis Disease Activity Scores (ASDAS) ESR and ASDAS CRP decreased respectively from 2.3 ± 0.5 to 1.9 ± 0.7 (p = 0.039) and from 1.9 ± 0.5 to 1.8 ± 0.8 (p = 0.388). Fasting did not affect significantly either compliance with chronic medications or tolerance.
CONCLUSIONS: Fasting can be a possible way to induce rapid improvement of rheumatic diseases activity. In addition, patients with a specific fear of drug intake during this period can be reassured, which will enhance the adherence to treatment. Key Points • Fasting during Ramadan, the ninth month of the Islamic calendar, consists of intermittent fasting observed from sunrise to sunset. • In this set of patients, beneficial effects of intermittent fasting were demonstrated on RA activity, but were less evident in patients with SpA despite a general trend towards improvement. • Fasting did not affect significantly either compliance with chronic medications or tolerance.
