Summary

ObjectiveObesity is a major risk factor for osteoarthritis (OA). Adipose tissues may be linked to OA development through secretion of potential proinflammatory cytokines including neutrophil gelatinase-associated lipocalin (NGAL). Our objective was to assess changes in serum NGAL after a low-calorie diet (LCD) and subsequent glucagon-like peptide 1 receptor agonist (GLP-1 RA) treatment.DesignA secondary analysis of a randomized, double-blinded, placebo-controlled trial in adults with overweight (BMI≥27 ​kg/m2) and symptomatic, early-to-moderate radiographic knee OA. Prior to randomization, participants underwent an 8-week LCD (week -8 to 0). Participants who lost min. 5 ​% of initial bodyweight were randomized 1:1 to liraglutide 3 ​mg/d or placebo for 52 weeks. Main outcome was change in serum NGAL from enrollment (week -8) to randomization (week 0). Other outcome was change in serum NGAL from week 0 to week 52 comparing liraglutide and placebo.Results168 participants were enrolled to the initial intensive diet intervention; 127 participants, with NGAL samples, were randomized. Following the 8-week diet intervention, NGAL concentrations rose by 93.0 ​ng/mL (95 ​% CI: 18.9 to 167.1, P ​= ​0.015), with no correlation to weight loss magnitude. 52 weeks of treatment with either liraglutide or placebo, liraglutide did not cause a greater decrease in serum NGAL (14.9 ​ng/ml, 95%CI: -92.1 to 121.7 ​ng/mL, P ​= ​0.78).ConclusionAn intensive 8-week calorie restriction was associated with a rise in serum NGAL. Compared to placebo, 52 weeks of liraglutide did not cause additional changes in NGAL. This indicates a complex pattern of proinflammatory cytokine-release during hypocaloric diet interventions.Trial registrationClinicaltrials.gov: NCT02905864.

  1. 01HumanRandomized controlled trialEfficacy outcome

    In adults with overweight and symptomatic knee osteoarthritis, liraglutide did not decrease serum NGAL more than placebo after 52 weeks (reported contrast 14.9 ng/mL; 95% CI -92.1 to 121.7; P = 0.78).

    In plain wordsIn adults with overweight and knee osteoarthritis, liraglutide did not lower NGAL significantly more than placebo.
