Strep
Throat
Strep throat is
one
of a
varied
range
of
conditions
caused
by
the
bacterium
known
as
group
A
Streptococcus
(
GAS
)
.
One
study
found
that recurrent
tonsillitis
(
RT
)
with
pediatric
group A Streptococcus (GAS) RT
had
smaller
germinal
center
s,
with an
underrepresentation
of GAS-
specific
CD4+
germinal center T
follicular
helper
(GC
–
TFH)
cells
(Dan,
et
al.,
2019).
This
translates
to a smaller
area
in
lymph
organs
where
B
cells
proliferate,
differentiate,
and
mutate
their
antibody
genes
. B cells/
lymphocytes
responsible for producing antibodies. B
lymphocytes
and CD4+ T cells are important cells
in the adaptive
immune
system
.
Some people have a genetically based weaker immune
response
to group A strep
bacteria
.
The
GAS bacteria
gained
entry
into
the
patient’s
respiratory
tract
and
multiplied.
This
triggered
an
inflammatory
response.
His tonsils b
ecame
enlarged
related
to
vasodilation,
increased
vascular
permeability,
which
allowed
white
blood
cells to
adhere
to the
vessels
and
surrounding
tissue
(McCance,
2019,
p.
195)
.
This caused
tonsilar
edema/swelling.
The cervical
lymphadenopathy
was caused as the immune system
moved
bacterial
products,
dead
cells,
and
other
inflammatory
material
through
the lymph
system’s
channels
(McCance, 2019, p. 195) The
patient’s
immune response
produced
the
fever.
Endogenous
pyrogens
create
a
beneficial
host
–
defense
reaction
during
infection
(McCance, 2019, p.
291).
Anaphylaxis
The angioedema (swelling of tongue and lips) and wheezing were signs and symptoms of anaphylaxis. This is an acute and possibly life-threatening emergency. This was caused by a Type I hypersensitivity reaction mediated by mast cells and basophils, most likely from the antibiotic. Sometimes the host response to an antigen is excessive, causing a damaging response while trying to be defensive. Anaphylaxis can occur immediately and can either be cutaneous or systemic (McCance, 2019, p. 256).
On a cellular level, anaphylaxis is a chain of events. IgE recognizes and binds to an antigen. The activated IgE fixates to mast cells and basophils, which initiates the release of chemical mediators such as histamine (Stone, Prussin, & Metcalfe). This then triggers a more intensified response, releasing more histamine. Respiratory distress occurs because histamine causes smooth muscle contraction, producing bronchial constriction; wheezing/stridor (McCance, 2019, p. 256). The tongue and lip swelling/angioedema are caused by the chemical mediators increasing vascular permeability, leading to fluids leaking from vessels (Theresa Capriotti, 2018).
Our text indicates that some people are genetically predisposed to have allergies, Type I in particular. This is called Atopic. If one parent has an allergy, 40% of offspring have a chance of allergies occurring, and 80% if both parents have allergies (McCance, 2019, p. 263). This happens because atopic persons make more IgE and have more Fe receptors on their mast cells.
I did not read where gender would play any part in Step throat or anaphylaxis. The patient was listed as NKDA and food allergies; it might have been prudent to ask if siblings or parents were allergic to any medications or foods.

Thomas Brooks NURS 6501 Week 1 initial Discussion Post
The assigned scenario assessment has shown the 16-year-old child tested positive for strep throat. “Strep throat is a painful condition that’s potentially life-threatening if not treated promptly. Research has found that children who have multiple strep infections in a year may have a genetic trait that makes it hard for them to fight the infection (Citroner,2019).” Therefore, genetics can play a role in the disease.
“According to the Centers for Disease Control and Prevention Trusted Source , strep throat is caused by a bacterial infection called group A Streptococcus. When group A strep is a recurring problem, the result can be utter misery. It’s one reason why children may have their tonsils removed. Now researchers at the La Jolla Institute for Immunology (LJI) have uncovered the first clues as to why some children may frequently contract group A strep. In a study published in the journal Science Translational Medicine on Feb. 6, researchers examined the surgically removed tonsils of 26 children between the ages of 5 and 18 years who had recurrent tonsillitis. They also looked at the tonsils of 39 children who had their tonsils removed for other reasons, such as sleep apnea. What they found is that tonsils from kids with repeat infections had a genetically based poor immune response to group A strep bacteria. When the medical histories of these children were checked, the researchers confirmed the problem did run in some families (Citroner, 2019).”
The patient is presenting with a temperature just below a low-grade fever also known as pyrexia which I believe to be a reaction to his infection. A person may have an increase in body temperature “because your body is trying to kill the virus or bacteria that caused the infection. Most of those bacteria and viruses do well when your body is at your normal temperature. But if you have a fever, it is harder for them to survive. Fever also activates your body’s immune system (Health, 2020).”
The pain, redness, and white exudate are due to the infection. The white spotting can be caused by “A group of bacteria called streptococcus. Your doctor can take a throat swab and do a quick test to tell if you have the infection. If the sample comes back positive, they’ll give you antibiotics to kill the bacteria. You may start to feel better in as little as a day, but the antibiotics need about 10 days to finish the job (Brennan, 2019).”
Once the patient mentioned had an anaphylactic reaction which “causes your immune system to release a flood of chemicals that can cause you to go into shock — your blood pressure drops suddenly and your airways narrow, blocking breathing. Signs and symptoms include a rapid, weak pulse; a skin rash; and nausea and vomiting (Mayo,2020)” it was critical that the patient be treated in order to ensure they do not stop breathing due to airway closure.
“Streptococcus pyogenes (Group A streptococcus) is a Gram-positive, nonmotile, nonsporeforming coccus that occurs in chains or in pairs of cells. Individual cells are round-to-ovoid cocci, 0.6-1.0 micrometer in diameter (Figure 1). Streptococci divide in one plane and thus occur in pairs or (especially in liquid media or clinical material) in chains of varying lengths. The metabolism of S. pyogenes is fermentative; the organism is a catalase-negative aerotolerant anaerobe (facultative anaerobe) and requires enriched medium containing blood in order to grow. Group A streptococci typically have a capsule composed of hyaluronic acid and exhibit beta (clear) hemolysis on blood agar (Todar, 2020).”
Although the infection strep throat can be healed through medical treatment and antibiotics it is important to remember that seeking medical attention early will always assist with receiving the best outcome possible.
