Insights
Adrenocorticotropic hormone (ACTH) offers an effective and safe treatment for acute gout, particularly for patients with comorbidities contraindicating traditional therapies like NSAIDs. Further research is needed to confirm its efficacy and safety.
Area of Science:
- Rheumatology
- Endocrinology
- Immunology
Background:
- Standard acute gout treatments (NSAIDs, colchicine, steroids) are often contraindicated in patients with common comorbidities (cardiovascular disease, hypertension, renal dysfunction, diabetes).
- There is a need for safer and effective therapeutic alternatives for acute gout in this patient population.
Purpose of the Study:
- To review existing evidence on the efficacy and safety of adrenocorticotropic hormone (ACTH) for acute gout treatment.
- To explore the potential mechanisms of action of ACTH in managing gout flares.
Main Methods:
- Conducted an electronic literature search across MEDLINE, Scopus, and Web of Science.
- Used keywords including 'ACTH' or 'adrenocorticotropic hormone' combined with 'gout' or 'crystal-induced arthritis'.
Main Results:
- ACTH demonstrates a favorable safety profile, making it suitable for patients with multiple comorbidities.
- Clinical evidence suggests ACTH is as effective as conventional gout treatments.
- Proposed mechanisms include steroid-independent anti-inflammatory effects via melanocortin receptor activation on macrophages and potential IL-1 antagonism.
Conclusions:
- ACTH presents a promising alternative therapeutic option for acute gout, especially in patients with contraindications to standard therapies.
- Further large-scale studies are warranted to rigorously assess ACTH's efficacy and safety compared to established treatments.
Abstract:
Treatment of acute gout consists of non-steroidal anti-inflammatory drugs (NSAIDs), colchicine and steroids. However, the typical patient with gout has multiple comorbidities such as cardiovascular disease, hypertension, renal dysfunction or diabetes/metabolic syndrome that represent contraindications to these therapeutic options. The aim of this study is to review the available evidence regarding the use of ACTH as an alternative therapeutic option for acute gout and explore potential mechanisms of action. We performed an electronic search (MEDLINE, Scopus and Web of Science) using the keywords ACTH or adrenocorticotropic hormone combined with gout or crystal-induced arthritis. ACTH appears suitable for patients with many comorbidities due to its good safety profile. Clinical evidence shows that ACTH is at least as effective as classic agents. The mechanism of action of ACTH in gout is not entirely known. Robust experimental evidence points to the direction that ACTH does not act solely by triggering the release of endogenous steroids but also appears to downregulate inflammatory responses by activating melanocortin receptors on innate immune cells, such as macrophages. Moreover, indirect evidence indicates that ACTH may have an IL-1 antagonistic effect. We propose that ACTH may be an alternative therapeutic option for gout in patients with multiple comorbidities. Large-scale studies assessing the efficacy and safety of ACTH compared to classic therapeutic options are needed.
