Understanding ACTH therapy not only enables healthcare professionals to make informed decisions but also empowers caregivers with the knowledge to navigate treatment options effectively.
What is ACTH?
ACTH, or adrenocorticotropic hormone, is a peptide hormone produced by the anterior pituitary gland. Its primary role is to stimulate the adrenal glands to produce and secrete cortisol and other corticosteroids. In the context of infantile spasms, ACTH is administered as a therapy to modulate the immune response and relieve the symptoms associated with the spasms. This hormone can be delivered in various forms, including injections and, in some rare cases, nasal sprays. The choice of ACTH as a treatment is tightly linked to its ability to address the underlying pathophysiological processes that contribute to spasms in infants.


Mechanism of Action
The mechanism of action of ACTH in the treatment of infantile spasms involves several biological and neurological pathways. ACTH exerts its effects primarily through the stimulation of cortisol release, which leads to reduced inflammation and modulation of the immune system.
- Corticosteroid Production: By promoting increased corticosteroid production, ACTH helps to minimize the neuroinflammatory responses that can provoke seizures in infants.
- Impact on Brain Activity: It is believed that ACTH may alter neurotransmitter levels in the brain, which can help stabilize neuronal excitability, thus reducing the frequency and intensity of spasms.
- Neuroprotective Effects: Some studies indicate that ACTH may have neuroprotective effects, securing brain function and development during critical growth phases.
The combination of these mechanisms underscores why ACTH has remained a cornerstone in managing infantile spasms, despite the development of alternative therapies. Health practitioners must weigh the benefits against potential side effects when considering ACTH therapy for their patients, as this will influence treatment outcomes significantly.
