Insights
Coronavirus disease 2019 (COVID-19) did not significantly alter children's sleep patterns. However, serum melatonin levels were higher in non-COVID-19 patients, suggesting a potential protective role for melatonin against severe COVID-19 in pediatric populations.
Area of Science:
- Pediatric Medicine
- Infectious Diseases
- Sleep Science
Background:
- Pediatric coronavirus disease 2019 (COVID-19) can affect various physiological parameters.
- Sleep disturbances are a common concern in children, especially during and after viral infections.
Purpose of the Study:
- To investigate serum melatonin levels in pediatric patients diagnosed with COVID-19.
- To analyze changes in sleep patterns among children with COVID-19 compared to a control group.
- To explore the potential impact of COVID-19 on pediatric sleep quality and melatonin regulation.
Main Methods:
- A descriptive, cross-sectional study design was employed.
- Serum melatonin levels and sleep parameters were compared between children with mild to moderate COVID-19 and a control group with non-COVID-19 respiratory infections.
- The Sleep Disturbance Scale for Children (SDSC) questionnaire assessed sleep patterns at present and six months prior to symptom onset.
Main Results:
- The study included 106 pediatric patients (80 in the COVID-19 group, 26 in the control group).
- No significant differences in serum melatonin levels were observed between the COVID-19 and control groups (p = 0.16).
- Sleep parameters, assessed via the SDSC questionnaire, showed no significant differences between groups at present or six months before symptom onset (p = 0.99).
Conclusions:
- COVID-19 infection did not appear to significantly impact the sleep parameters of pediatric patients.
- While serum melatonin levels were elevated above the reference range in all children, they were higher in the control group.
- Elevated melatonin levels in COVID-19 patients suggest a potential protective role against disease severity in children.
Background/Aim:
This study aimed to analyze the serum melatonin levels and changes in sleep patterns in pediatric patients with coronavirus disease 2019 (COVID-19).
Materials And Methods:
This study was designed as a descriptive, cross-sectional study. Serum melatonin levels and sleep parameters of children with the diagnosis of COVID-19 who had mild and moderate disease (i.e., COVID-19 group) were compared with those of children admitted with non-COVID-19 nonspecific upper respiratory tract infection (i.e., control group). The sleep disturbance scale for children (SDSC) questionnaire was applied to the participants› primary caregivers to analyze their sleep patterns at present and six months before symptom onset and to investigate the impact of COVID-19 on sleep patterns.
Results:
The entire study cohort consisted of 106 patients. The COVID-19 group included 80 patients, while the control group consisted of 26 patients. The mean serum melatonin levels were 136.72 pg/mL and 172.63 pg/mL in the COVID-19 and control groups, respectively (p = 0.16). There was no significant difference between the groups in terms of 6 subcategories of the SDSC questionnaire regarding the present time and 6 months before symptom onset. The total SDSC scores were also similar in two different evaluation time points described above (p = 0.99)
Conclusions:
We conclude that COVID-19 did not impact the sleep parameters of children. Serum melatonin levels of all patients were higher than the reference range; however, they were higher in the non-COVID-19 patient group than the COVID-19 group. Since serum melatonin levels were higher than the reference values in children with COVID-19, and this disease is significantly less morbid in children, melatonin may have protective effects against COVID-19.

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
