Anemia and HIV
Anemia has always been a problem for HIV+ people. Almost
half of all HIV+ people have mild or moderate anemia. Factors that are linked
to a higher rate of anemia in HIV+ people include:
Being a woman
Being African-American
Lower CD4 cell counts
Higher viral load
Taking AZT (Retrovir or zidovudine)
Although anemia is a common condition for HIV+ women, it
often goes unrecognized and untreated. If left untreated, anemia is strongly
associated with HIV disease progression and an increased risk of death. In
fact, recent studies show that low hemoglobin levels may be as useful an
indicator for predicting disease progression as low CD4 cell counts and other
common prognostic methods. The good news is that with diagnosis and treatment
the affects of anemia can be greatly reduced.
Anemia and HAART
Although the rate of serious anemia has dropped
considerably since people started using HIV drug combinations, anemia
continues to affect up to 30% of HIV positive people on HAART.
Recent studies show that when starting HAART treatment,
individuals with a hemoglobin level greater than 12 were more likely to adhere
to treatment and achieve viral suppression within 6 months. These study
results suggest that treating hemoglobin may produce better outcomes for
adherence and viral suppression.
Anemia is a shortage of red blood cells. It occurs:
When the body produces too few red blood cells
When the body loses too many red blood cells
When red blood cells are destroyed faster than they
can be replaced
Anemia can also occur when there is a shortage of
hemoglobin (HGB). HGB is a protein found in red blood cells. Its job is to
carry oxygen from the lungs to the rest of the body. People who have anemia
cannot carry as much oxygen in their blood and don't feel as good as people
with a normal level of HGB.
Anemia causes fatigue and can lower quality of life.
Symptoms include:
Severe fatigue
Difficulty breathing
Rapid heart rate
Pale skin
Decreased pinkness of the lips, gums, lining of the
eyelids, nail beds, and palms
Feeling cold
Confusion or loss of concentration
Dizziness or fainting
Sadness or depression
Among HIV+ women, anemia is often caused by a shortage of iron, vitamin B12, or folic acid (a vitamin in the B complex
group).
Low iron is most commonly due to blood loss from
internal bleeding, frequent nosebleeds, or excessive or prolonged menstrual
periods
A shortage of folic acid can lead to megaloblastic
anemia. This causes the red blood cells to become pale and enlarged
Other causes of anemia include:
HIV infection itself
Many opportunistic infections related to HIV disease
Kidney or bone marrow damage
Some thyroid conditions
Many drugs that are commonly used to treat HIV and
related infections
Simple blood tests can usually diagnose anemia by
measuring hemoglobin and hematocrit (the percentage of red blood cells in the
total blood volume) as part of a complete blood count (CBC).
Hemoglobin levels for women should be at least 12 g/dL.
A hemoglobin level of less than 6.5 g/dL is too low and could lead to a
life-threatening situation
Hematocrit levels for women should be 35 percent to
46 percent
Treating anemia improves the health and survival of HIV+
people. Like most conditions, the key to treating anemia is directly linked to
the cause. If chronic bleeding is the main source of the problem, it should be
identified and controlled.
If iron levels are low, they should be corrected. (Iron
is often low in women.) Taking iron tablets can restore levels, but too much
iron isn't a good thing.
Some studies show that supplementing with iron should be
done with caution in people with HIV infection, HCV infection, or both because
iron has been shown to make some drugs less effective. There is also a
suggestion that iron might increase HIV replication.
If your anemia is due to a shortage in iron or vitamins,
you may be able to modify your diet to include foods rich in these nutrients.
Iron is found in red meat, seafood, fish, and fortified bread and cereals.
Folic acid is found in dark greens, asparagus, lima beans, spinach, and beef
liver. If your vitamin B12 levels are low, you may need B12 injections or
formulations of B12 you put under your tongue, no matter how much you get in
your diet. This is because some people cannot absorb this vitamin from food or
oral supplements.
If a drug you are taking is causing anemia, it may be
necessary to stop taking that drug. When advanced HIV is the cause of anemia,
HIV treatment may improve symptoms.
There are also medications available to treat anemia
directly. These include the injectable drug erythropoietin (EPO, Epogen, and
Procrit), which has been used to treat mild-to-moderate anemia. In some cases,
blood transfusions may be required.
Anemia is a common condition in HIV+ women. It can cause
feelings of fatigue, lower your quality of life and increase the risk of HIV
disease progression. If you are experiencing any of the symptoms listed above,
talk to your doctor. He or she can run tests to determine if anemia is the
problem. If so, your doctor will look for the cause of the anemia and suggest
treatment options.
