Management of Insomnia01:19

Management of Insomnia

763
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

The Pineal Gland01:02

The Pineal Gland

6.5K
The pineal gland, a diminutive endocrine structure named for its pinecone-shaped appearance, is situated atop the third ventricle within the diencephalon region of the forebrain. This gland, composed of secretory cells known as pinealocytes arranged in compact cords and clusters around dense particles of calcium salts, plays a pivotal role in hormonal regulation.
The primary secretion of the pineal gland is the hormone melatonin, derived from serotonin. The concentration of melatonin in the...

Sedatives and Hypnotics Drugs: Miscellaneous Agents

782
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
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...

REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

2.3K
REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
RBD is significantly associated with...

Narcolepsy01:07

Narcolepsy

719
Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.

Area of Science:

  • Immunology
  • Endocrinology
  • Rheumatology

Background:

  • Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with complex pathophysiology.
  • Melatonin, a hormone regulating circadian rhythms, has immunomodulatory properties.
  • The role of melatonin in SLE pathogenesis remains unclear.

Purpose of the Study:

  • To investigate plasma melatonin levels in SLE patients.
  • To explore the association between melatonin levels and clinical/laboratory features of SLE.

Main Methods:

  • Enzyme-linked immunosorbent assay (ELISA) was used to measure plasma melatonin.
  • 90 SLE patients and 90 healthy controls were included.
  • Clinical and laboratory data were collected for SLE patients.

Main Results:

  • No significant difference in plasma melatonin levels was observed between SLE patients and controls (P=0.026).
  • Plasma melatonin levels did not differ significantly between SLE patients with or without nephritis (P=0.714).
  • No significant difference in melatonin levels was found based on SLE disease activity (P=0.791).
  • The presence of IgM was associated with melatonin levels in SLE patients (P=0.031).

Conclusions:

  • Plasma melatonin levels are comparable between SLE patients and healthy controls.
  • The study suggests no direct correlation between melatonin levels and major clinical manifestations of SLE.
  • Further investigation is warranted to fully elucidate the potential role of melatonin in SLE.
