The Breast is Yet to Come
(Gynecomastia and Mastitis)
Gynecomastia can come
from a variety of origins. An excess of estrogen, the female
sex hormone, causes proliferation of female ductal (glandular)
tissue and can induce the same growth for the male breast.
There is also evidence that androgens (male sex hormones)
can cause changes and abnormal breast tissue enlargement.
Also, androgens can be converted to estrogenically active
metabolites; this is especially seen in abnormal testicular
function. So how does this apply to patients who are HIV positive?
Well, many HIV-positive individuals have a syndrome called
hypogonadism. This condition is associated with increases
in production of pituitary gonadotropins (hormones produced
by the brain); the pituitary hormone then sends messages to
various glands in other parts of the body to either produce
or shut off production of various sex hormones. Thus hypogonadism
can lead to overproduction of estrogen or underproduction
of testosterone, both by the testicles.
Also, many individuals with
HIV are being treated with a plethora of hormonal drugs: testosterone,
decadorabolin, oxandrin, Anadrol, Androgel, and testosterone
creme. Some of these drugs can potentially lead to estrogenically
active metabolites and/or affect the message system of various
sex hormones. In a majority of instances, these agents improve
sexual libido and potency; however, sometimes these same drugs
can cause sexual dysfunction, often seen with testicular atrophy
and a loss of ejaculation capacity. Thus, over-doing it with
these agents can lead to hormonal imbalances and gynecomastia.
In clinical practice my treatment
approach to the HIV-positive individual with gynecomastia
has varied. Sometimes using a variety of different agents
can stimulate the testes to produce its own testosterone.
This often improves testicular regeneration and improved quantity
of ejaculate. When indicated, anti-estrogen pills can often
be helpful.
Another symptom, discomfort
and tenderness of one or both nipples, often referred to as
mastitis, is frequently seen in the HIV clinic. This also
can occur due to hormonal imbalances. Additionally, one should
know that “tit play” can exacerbate this condition. Anti-inflammatory
medications are helpful and when the nipple is infected may
require antibiotic and local treatment.
A Fat Breast is a Happy
Breast?
The Breast Fat Accumulation
of Lipodystrophy in Males and Females
Fat accumulation has
occurred in various areas of the body in HIV-infected individuals.
Controversial and debated, research is attempting to identify
the cause. Abnormal fat changes may be the result of HIV itself
versus specific antiviral therapies. Among HIV specialists
and researchers, mitochondrial dysfunction (a specific cellular
aberration) is often bandied about as the primary cause of
lipodystrophy and fat accumulation. Most individuals are aware
of fat accumulation manifesting as “buffalo humps” and “protease
paunches,” so why not the breast? Not surprisingly, increased
breast size has been reported with both males and females.
My approach to a fatty breast
is similar to treating fat accumulation in other body parts.
Each person with a problem is approached from an individual
patient basis and vantage point. Some patients have more options,
including changing one’s antiviral therapy. For example, a
stable patient on protease inhibitors who has developed a
higher propensity for fat accumulation may benefit from switching
to a non-nuke (Sustiva or Viramune). Another option that should
be on the table for consideration is treatment with growth
hormone (Serostim). Serostim improves the growth of lean body
mass while burning body fat. In some individuals it has been
shown to decrease or improve fat accumulation syndromes, such
as buffalo hump and abdominal visceral (organ) fat buildup.
Finally, a recent report from Paris has discussed using a
testosterone derivative called Andractim or DTH (dihydrotestosterone)
topically for gynecomastia. The report is not clear whether
the breast enlargements being treated with this modality is
due to fat accumulation or is of hormonal origin.
Conclusion
One would hope that one never
has to face breasts against one’s will! However, with the
evolving field and treatment of HIV and its related complications,
breast tissue can emerge as a challenge for both patients
and their physicians. The widespread use of hormonal agents
to combat hypogonadism and wasting has added to the frequency
of gynecomastia. Alternatively, lipodystrophy has increased
fatty breast tissues in some HIV-positive individuals. Patients
should be aware of treatment options, as well as the risks
of using and over-abusing testosterone. Holidays from hormonal
replacement treatment are encouraged and anti-estrogens can
improve and avert the onset of gynecomastia. As mentioned
in many of my articles, discussing treatments mentioned in
this column with your personal physician is always prudent.
I encourage comments and questions.
