Glucocorticoid Toxicity

PMB Lead: Dr Mar Pujades Rodriguez, University Academic Fellow, University of Leeds

Clinicians struggle with management of GCA, particularly in terms of the difficult balance between the clinical knowledge of the long-term cumulative toxicity of glucocorticoid (steroid) therapy against the fact that glucocorticoids suppress inflammation and enable patients to continue their everyday functions.

Background

For many years, Leeds has played an important role in phenotyping GCA patients, which demands considerable clinical acumen [Bird et al., 1979; Leeb and Bird, 2004; Pease et al., 2005; Mackie et al., 2010]. Although prednisolone tablets are inexpensive, the real healthcare costs of long-term steroid therapy are immense. In addition, there are well-known consequences including obesity, diabetes, cardiovascular disease, and osteoporosis, and less well-characterised consequences including adrenal suppression, glucocorticoid-related myopathy and impaired wound healing. These toxicities interact with age-related co-morbidity resulting in devastating and costly patient outcomes, including falls, fractures and dependency.

In Western healthcare systems, overall lifespan is not curtailed in GCA compared to the general population, so healthcare costs of the disease are high. Patient engagement activities have demonstrated that the adverse effects of glucocorticoids therapy can dominate the lives of patients, far more than is usually appreciated by their doctors and often far more than the original disease. While the disease is treatable, large doses of glucocorticoids are needed for many patients with relapsing disease, however, many of the glucocorticoid-related adverse effects are irreversible and continue long after they are stopped. There is therefore a real unmet need in GCA for an alternative to prednisolone that has a more favourable side-effect profile without substantial loss of efficacy. There is a paucity of clinical trial data to support the use of alternative immunosuppressants compared to other autoimmune disease, although promising data is emerging for some biological therapies, particularly Tocilizumab. Once available for routine use in the NHS, these newer treatments would have an enormous impact for patients, and would be likely to reduce overall healthcare costs.
