Melatonin mitigates flu-induced lung injury

Based on 3 Researches

Huo C, Tang Y, Li X, Han D, Gu Q, et al. Melatonin alleviates lung injury in H1N1-infected mice by mast cell inactivation and cytokine storm suppression. PLoS Pathog. 2023;19:e1011406. doi:10.1371/journal.ppat.1011406

We explored the potential of melatonin as a treatment for H1N1 flu infection. In our study, we found that melatonin, a powerful antioxidant and anti-inflammatory compound, could significantly protect against the flu in both laboratory tests and in living mice.

Our findings showed that higher local levels of melatonin in the nose and lungs correlated with lower death rates from the virus. In fact, melatonin-deficient mice had much higher mortality rates, which were notably reduced when treated with melatonin.

We discovered that melatonin primarily works by targeting mast cells, which are important players in the body’s immune response. By suppressing the activation of these cells after H1N1 infection, melatonin helps control the release of inflammatory proteins, leading to less damage in lung tissue. This mechanism highlights how melatonin treatment can prevent serious lung injury caused by the virus, opening up new avenues for post-flu recovery strategies.

We focused on the effects of oral melatonin on anxiety and pain in children during the stressful process of venipuncture. In a double-blind, randomized controlled trial, we found that administering 0.5 mg/kg of melatonin 30 minutes before the procedure significantly reduced both pain and anxiety levels compared to a placebo.

The results showed that only 18.8% of the kids receiving melatonin reported pain, while 78.2% in the placebo group did. Furthermore, anxiety affected 44.6% of the melatonin group compared to 94.1% of those in the control group.

While melatonin appeared to improve experiences during venipuncture, its impact on the success rate was not statistically significant.

Based on 7 Researches

Williams G, Waterhouse J, Mugarza J, Minors D, Hayden K. Therapy of circadian rhythm disorders in chronic fatigue syndrome: no symptomatic improvement with melatonin or phototherapy. Eur J Clin Invest. 2002;32:831.

We evaluated whether melatonin and bright-light phototherapy could help alleviate symptoms of chronic fatigue syndrome (CFS). In a controlled study with thirty participants, we assessed the effectiveness of these treatments by measuring various symptoms over several weeks.

Unfortunately, we found that neither melatonin nor phototherapy led to significant improvements in the patients’ symptoms or overall health. Our findings suggest that these treatments shouldn't be promoted for CFS unless proven beneficial.

I was taking benzodiazepines for insomnia during menopause, but they didn’t work and left me dazed in the morning. After hearing positive feedback, I tried this and was astonished by its effectiveness. I felt drowsy within 20 minutes and slept through the night. I found it a bit strong, so I plan to cut the dosage next time. The size is small and tasteless, making it easy to take. I believe it offers great value for money.

Reflux details

Melatonin reduces reflux esophagitis damage

Based on 16 Researches

Lahiri S, Singh P, Singh S, Rasheed N, Palit G, et al. Melatonin protects against experimental reflux esophagitis. J Pineal Res. 2009;46:207. doi:10.1111/j.1600-079X.2008.00650.x

We explored how melatonin can protect the esophagus from reflux esophagitis (RE), a condition where stomach contents flow back into the esophagus, often causing painful inflammation. In our research with rats, we found that melatonin pretreatment resulted in significantly fewer bleeding lesions and lower levels of harmful lipid peroxidation typically caused by RE.

Additionally, melatonin helped replenish important antioxidants in the esophagus, suggesting its potential to neutralize free radicals that contribute to tissue damage. As we delved into the immune response, we observed that melatonin decreased the levels of certain pro-inflammatory cytokines, like TNF-alpha and IL-6, while keeping the levels of the anti-inflammatory cytokine IL-10 steady.

Interestingly, when we tested a melatonin receptor blocker, luzindole, we discovered that this approach did not hinder melatonin's protective effects. This indicates that melatonin works its magic in a receptor-independent way as well, not just through its antioxidant properties but also by modulating inflammation. Overall, we found that melatonin could be a beneficial ally for those suffering from reflux esophagitis, providing insights for future treatment strategies.

Headache details

Agomelatine relieves hypnic headaches

Based on 15 Researches

Xu SY, Li L, Sun WX, Shen JY, Li CX. Case report: Hypnic headache responds to agomelatine-a potential prophylactic treatment option. Front Neurol. 2023;14:1179391. doi:10.3389/fneur.2023.1179391

We explored how melatonin-based treatments, particularly agomelatine, can affect headaches, focusing on hypnic headaches (HH). This form of headache typically occurs during sleep, disrupting the rest of those affected. A fascinating case of a 58-year-old woman who experienced these nocturnal headaches for three years demonstrated the potential benefits of agomelatine.

After being prescribed 25 mg of agomelatine at bedtime, she reported an impressive 80% reduction in headache frequency and severity within a month. Remarkably, her headaches completely resolved after three months, allowing her to discontinue the medication.

This case highlights the importance of exploring prophylactic treatments aimed at reducing nighttime awakenings caused by HH. Given the significant impact these headaches can have on sleep quality in older populations, treatments that target melatonin receptors could offer a promising avenue for relieving this condition.

Melatonin linked to nausea management

Based on 2 Researches

Söderquist F, Janson ET, Rasmusson AJ, Ali A, Stridsberg M, et al. Melatonin Immunoreactivity in Malignant Small Intestinal Neuroendocrine Tumours. PLoS One. 2016;11:e0164354. doi:10.1371/journal.pone.0164354

We explored how melatonin could affect nausea in patients with small intestinal neuroendocrine tumors (SI-NETs). Our research involved studying tumor tissue from 26 patients, examining their primary tumors alongside metastases for the presence of melatonin and its receptors.

Interestingly, we found that higher melatonin levels in the body were linked to reported experiences of nausea. Specifically, patients with higher plasma melatonin levels at both time points indicated more frequent nausea occurrences. This underscores the potential role of melatonin in influencing nausea symptoms.

However, it's notable that in those cases where the disease was stable or improving, plasma levels of melatonin dropped after treatment, suggesting a complicated relationship between melatonin levels and treatment responses. These findings provide some valuable insights into the endocrine roles of melatonin in SI-NETs and signal a need for future studies to further dissect these relationships.

We investigated how melatonin affects patients with obstructive sleep apnea and insomnia. In a double-blind trial, thirty patients received either 10 mg of melatonin or a placebo for a month.

The results were striking; those taking melatonin reported better sleep quality, less daytime sleepiness, and greater adherence to their PAP devices. Improvements were noted across several assessments: the Pittsburgh Sleep Quality Index, Insomnia Severity Index, Epworth Sleepiness Scale, and Functional Outcomes of Sleep Questionnaire showed significant gains for the melatonin group.

Thus, melatonin appears to be a promising option to enhance sleep quality and treatment compliance in this challenging patient group.

We developed a new way to deliver melatonin for those struggling with insomnia by creating microneedles made from silk fibroin. These tiny needles are designed to improve how the body absorbs melatonin, making it easier for people to get to sleep and stay asleep.

Our research shows that these microneedles can release melatonin steadily over a period of 11 hours. When we tested it on animals, we found that the microneedles maintained stable levels of drug in the bloodstream for up to 8 hours. This is promising news for individuals who may need help with their sleep cycles.

Additionally, the microneedles not only helped regulate sleep but also made a noticeable difference in anxiety levels in insomnia model rats. By improving the disrupted circadian rhythms, melatonin loaded into these microneedles could lead to significant therapeutic benefits.

We believe this innovative approach could enhance patient compliance and provide effective sleep aid for many in need. It’s an exciting development in the field of transdermal drug delivery for improving sleep quality and overcoming insomnia.

I regularly buy this for my son, who has orthostatic disorder. He struggles to sleep at night and has difficulty waking in the morning, often feeling ill. A pediatrician recommended this to him when he was 15, and while waking up hasn't improved, it has helped his sleep quality. He still uses it as he can now fall asleep more easily. I hope other children with similar conditions find relief too.
