From the Guidelines
Melatonin should be used with extreme caution in someone with lupus, Ehlers-Danlos syndrome (EDS), and malignant cardiovascular syncope, and only after consulting with their healthcare provider. For patients with these conditions, it's generally recommended to start with a low dose of melatonin (0.5-1mg) taken 30-60 minutes before bedtime. Melatonin may potentially exacerbate autoimmune conditions like lupus due to its effects on the immune system, as it can stimulate immune function which might increase inflammation in lupus patients 1. For those with EDS, which often involves autonomic dysfunction, melatonin's effects on blood pressure and heart rate could potentially worsen cardiovascular symptoms. This is particularly concerning for patients with malignant cardiovascular syncope, as melatonin may influence blood pressure regulation and potentially trigger syncope episodes. If approved by a healthcare provider, the patient should monitor for side effects such as dizziness, headaches, or increased syncope episodes, and discontinue use if symptoms worsen. Alternative sleep strategies like consistent sleep schedules, limiting screen time before bed, and cognitive behavioral therapy for insomnia might be safer options for these patients. The most recent guidelines for the management of REM sleep behavior disorder recommend the use of melatonin, but these guidelines do not specifically address the use of melatonin in patients with lupus, EDS, and malignant cardiovascular syncope 1. However, given the potential risks, it is essential to prioritize caution and carefully weigh the benefits and risks of melatonin use in these patients. In general, the use of melatonin in patients with complex medical conditions should be individualized and guided by a healthcare provider, taking into account the patient's specific needs and medical history. The patient's healthcare provider should closely monitor their condition and adjust the treatment plan as needed to minimize the risk of adverse effects. It is also important to note that the evidence for the use of melatonin in patients with lupus, EDS, and malignant cardiovascular syncope is limited, and more research is needed to fully understand the potential benefits and risks of melatonin use in these patients 1.
From the Research
Melatonin Use in SLE and EDS Patients with Malignant Cardiovascular Syncope
- There are no direct studies on the use of melatonin in patients with systemic lupus erythematosus (SLE) and Ehlers-Danlos syndrome (EDS) who experience malignant cardiovascular syncope.
- However, studies suggest that melatonin may have protective effects on endothelial function in SLE patients, which could potentially benefit patients with cardiovascular syncope 2.
- One study found that melatonin prevents endothelial dysfunction in SLE by activating the nuclear receptor retinoic acid-related orphan receptor-α, which may help to reduce the risk of cardiovascular disease 2.
- Another study found that SLE patients have a higher prevalence of depression and anxiety, which may be related to their cardiovascular risk profile 3.
- A study on cardiovascular disease in SLE found that patients with SLE are at increased risk for accelerated atherosclerosis and cardiovascular events, and that endothelial dysfunction is a key factor in this process 4.
- Melatonin levels have been found to be lower in SLE patients compared to healthy controls, and serum melatonin levels may be a useful diagnostic tool for SLE 5.
- A case report described a patient with SLE who presented with cardiac conduction abnormalities and syncope, highlighting the importance of considering cardiac manifestations in patients with SLE 6.
