A case report links cocaine usage to sickle cell trait and
states that cocaine may cause those with the sickle cell trait to exhibit
symptoms experienced by those with sickle cell anemia. Sickle cell is a mutation in an amino acid in
a hemoglobin gene. Sickle cell trait is
the heterozygous version of this mutation, and is very common in the African
American population. Sickle cell anemia is the homozygous version of the
mutation, and though it is less common, the symptoms are always seen in those
with sickle cell anemia. Symptoms can be
seen in those with the trait, though it is a rare occurrence. A woman with sickle cell trait was emitted to
an emergency department with abdominal pain.
She started feeling better then pain began increasing and needed breathing
support. While operating, surgeons found
that her colon was not receiving enough oxygen , her spleen tissue was dead,
and the cells of the surrounding layer of the abdomen had died. Organ failure occurred after the operation
and the woman passed away. Pathology
showed that red blood cells had sickled throughout the omentum, spleen, colon,
and terminal ileum, and no bacteria and fungi were detected. It was known that the woman had used
cocaine. Catecholamines circulate within
the bloodstream, and an increase in the circulating concentration is associated
with cocaine use. These higher
concentrations can ultimately cause less oxygen to get to the desired location,
which then causes red blood cells to sickle and ultimately have damaging
effects on many organs, as seen with the woman in the report.
