Corticosteroids
By Tash Hughes of Word Constructions
Corticosteroids are a group of powerful
drugs that are based on human hormones.
What are they?
Corticosteroids are steroids, along
with various other drugs and naturally occurring hormones.
They are manufactured based on the hormone
cortisol. In the 1940s, corticosteroids were isolated
from the hormones and introduced as medicines that produced
results that appeared miraculous.
There are two types of corticosteroids,
the glucocorticoids and the mineralacortoids. Medically,
the glucocortoids are used more often and this term
is often used interchangeably with corticosteroids.
Glucocortoids work on the immune system,
stopping the production of substances that cause allergic
reactions and inflammation.
What is coritsol?
Cortisol is a hormone produced by the
adrenal glands in humans. It is important in regulating
the water/salt balance in the body and the metabolism
of fats, proteins and carbohydrates.
This hormone is a steroid and is made
from cholesterol. It can affect the stress responses,
behaviour and the immune response.
When are they used?
Glucocortoids are usually used to treat
inflammation and allergic responses.
Common issues treated with glucocortoids
include:
- Arthritis,
especially rheumatoid arthritis
- Asthma
- Dermatitis
and skin conditions
- inflammatory
bowel disease
- Lupus
- Breathing
problems
- BOOP
- Digestive
problems
- Eye problems
- Hormone
replacements
Corticosteroids are also used to help
the body accept a transplanted organ.
Which glucocortoid, the dosage and the
length of treatment depend on the problem being treated.
What about side effects?
There are a number of side effects common
to corticosteroid use, although most effects are reversible
(that is, they go away when you stop using the drug.)
In some people, corticosteroids can
cause major problems so these are not drugs used without
a good medical reason for doing so. The side effects
are more common in long term users of the drugs so doctors
usually prescribe the smallest does
for the shortest time that will solve the problem so
that side effects are minimised as much as possible.
Some of the common side effects are:
- High blood
pressure
- Increased
appetite and weight gain
- Increase
blood sugar levels and possibly diabetes
- Thinning
of the skin
- Slow healing
of wounds
- acne like
marks on the skin
- osteoporosis
- fatty areas
on the chest, face, upper back and stomach
- bruising
easily
- cataracts
- psychological
affects (e.g. mood swings, insomnia, depression,
excitement, delirium)
- a hip problem
called aseptic necrosis (very rare)
- a round
face that looks puffy
- irregularities
in periods
- drug induced
Cushing’s Syndrome
As glucocortoids act on the immune system,
these drugs can make the patient more susceptible to
infections during treatment. In particular, people taking
corticosteroids should avoid exposure to chicken pox
and measles, the oral polio vaccine
and people who have recently taken the oral polio vaccine.
Taking these drugs during pregnancy
may cause birth defects and they can pass through breast
milk so careful consideration is required before offering
these women coticosteroids.
Side effects are more common when the
drugs are taken orally (by tablets or liquid medicines.)
Stopping treatment
As corticosteroids are so powerful,
they need to be stopped slowly, rather than going from
a large dose to nothing.
During treatment, the adrenal glands
will stop producing cortisol. By slowing reducing the
dosage of corticosetroids, the adrenal gland can restart
making the cortisol hormone.
It can take months or even a year to
reduce a high dosage of corticosteroids enough for someone
to comfortably stop taking the drug.
