Patient is consistently hypertensive with blood pressures in the range of 130/70. She is currently
afebrile but has spiked temperatures at a maximum of 102.3*F in the past without identifiable
cause. Febrile episodes have been brief in length and have been better controlled over the past 36
hours. Respirations on admission were initially elevated at 22 bpm, but have since normalized.
Patient is mildly hypoxic with an O2 saturation of 91% when on room air, but this is resolved
with the administration of 2L oxygen via nasal cannula.

History of Present Illness (discuss clinical course from admission until current date):
The patient, Mrs. H, is a 89 year old caucasian female who presented to the Lynchburg
Emergency Department on 2/01/2018 with mental health status that had declined that day. She is
a resident of Westminster Canterbury and was accompanied by a generational aide. Due to the
patient’s declining mental state, it was not possible to obtain a detailed history from her, ergo
most details about her condition leading up to admission were obtained from the patient’s aide.
Mrs. H had visited the ED the day before; x-rays taken at that time were consistent with
pneumonia, however the patient refused blood work or any further medical intervention and
returned to her home. She was given Levaquin at that time. Per her aide, no fever, chills, or
unusual shortness of breath have been noticed. Mrs. H does have a moderate cough, which
produces small amounts of whitish/yellowish sputum. The patient denies any headache, chest
pain, or blurred vision. She was found to be mildly hypoxic (91% oxygen saturation) upon
examination and her respiratory rate was elevated at 22bmp. She was admitted to the pulmonary
unit of LGH for further evaluation and treatment of suspected sepsis.
Past Medical History
The patient has a history of atrial fibrillation for which she is prescribed Xanthol

Pathophysiology
!Mrs. H is a 89 year old Caucasian female who presented to Lynchburg
Emergency Department on 2/01/2018. She had visited the ED the previous day for
pneumonia-like symptoms. X-rays done at that time were consisted with pneumonia
findings and Levaquin was administered. After refusing further treatment or testing,
Mrs. H was released to her home. On 2/01 she was transported back to the ED via
EMS services for altered mental status. Mrs. H was accompanied by a CNA who cares
for her at Westminster Canterbury; due to Mrs. H’s confused state, all medical history is
courtesy of her aide. Per her aide, no fever, chills, or unusual shortness of breath have
been noticed. Mrs. H does have a moderate cough, which produces small amounts of
whitish/yellowish sputum. The patient denies any headache, chest pain, or blurred
vision."
!Initial examination findings indicated that Mrs. H was significantly febrile
(101.7*F), tachypnic (22bpm) and suffering from poor oxygen perfusion (91% oxygen
saturation). She was admitted to the pulmonary unit of LGH for further evaluation and
treatment of suspected pneumonia and septic infection. The following is a discussion
of the pathophysiology of her pneumonia and sepsis diagnosis, as well as the rationale
behind her treatment strategies."
!Pneumonia is an infection of the lungs that occurs when pathogenic invaders
enter the alveoli and overcome the immune defenses, colonizing and triggering an
inflammatory response causing in the alveoli to fill with fluid. Although pneumonia can
be caused by a number of factors: bacteria, viral, or protozoan, because Mrs. H’s
infection is believed to be bacterial in nature, our focus will remain primarily on this
source. "
! 20
Student Name: Keri Bennett
!Because of the multi-faced nature of immunity, in order for a pneumonia
infection to occur, several branches of the immune system must be breached (Ackley,
2017). One of the first and most important lines of defense in the reparatory tract is the
mucoid secretions produced by the pulmonary goblet cells (Porth, 2011). Mucus
prevents bacterial growth in two ways. First, it physically traps the invading pathogens
before they reach the delicate lung tissues, and second, the naturally basic pH of
mucus discourages bacterial growth (Seeley, 2016). Although the high pH of mucus
prevents much pathogenic growth, it is possible for some bacteria to take up residence
within it. Staphylococci, for instance, are capable of surviving in a wide range of acidic
and basic environments and are responsible for the majority of factorial pneumonias
(Batzing, 2012). Normal pH values in tracheal mucus range from 6.9–9.0, but infection
can lower pH values to as low as 5.8. The viscosity of mucus increases with acidity,
making it more difficult to expel from respiratory passages (Porth, 2013)."
!Pulmonary secretions containing trapped bacteria must constantly be moved to
the top of the trachea and excreted. One of the ways in which mucus is moved is via
the cilia. These hair-like structures move in wave-form to locomote mucoid secretions
out of the lungs and into the esophagus for elimination. If the cilia are damaged via
smoke consumption, genetic disorders, or medication, there is stasis of fluid and the
risk for infection is increased (Seeley, 2016). Additionally, significantly lowered ciliary
beating function is observed below pH 7.0 for bronchi and below pH 5.0 for
bronchioles. These changes in pH, while not permanently damaging to the cilia, impair
mucocillary clearance even further and play a significant role in the development of
pneumonia (Linares, 2011). While the sticky consistency of mucus is beneficial in that it
traps mucus during breathing and prevents it from reaching the lungs, in the event of
mucoid stasis, it can act as a medium for pathogens to take up residence and colonize
! 21

(Porth, 2013). Mrs. H is prescribed Guaifenesin, an expectorant that works by reducing
the viscosity of pulmonary secretions. Thus, the ciliary actions are more effective and
the efficiency of the cough reflex is improved, allowing secretions to be removed
(Skidmore-Roth, 2018)."
!Another way in which mucoid secretions are moved through the respiratory tract
is by breathing. The movement of air fills the lowest alveoli sacs, displacing mucus and
also assisting the ciliary elevator in moving mucus out of the respiratory tract. Opening
the alveolar sacs not only helps with the prevention of fluid stasis, it also is important to
ensure adequate blood flow, lung elasticity, and oxygen delivery, a well as the
prevention of inflammatory reactions which could further cause respiratory issues
(Ackley, 2017). When the sacs are closed, blood flow is decreased, potentially could
leading to tissue necrosis, and resulting in a lack of immune cells delivered to the
tissue. Because the majority of initial immune modulators are transported in the blood,
it is vital that blood reach all areas of the body to precipitate the removal and
destruction of pathogenic material (Remick, 2017)."
!Mrs. H has been prescribed nebulizer albuterol treatments to relax the smooth
muscle of the airway and dilate bronchioles, allowing for increased air circulation in the
lower parts of the lungs. Bronchial smooth muscle is innervated by beta2-adrenergic
receptors, the stimulation of which activates Gs adenylyl cyclase cyclic AMP pathway
resulting in smooth muscle tone reduction. Albuterol also leads to smooth muscle
membrane hyperpolerization and relaxation by acting as a smooth muscle by
increasing the conductance of calcium and potassium channels, possibly by the
regulation of capacitative calcium ion entry by small G proteins. Albuterol may also
exert an influence on the function of mast, cells, basophils, eosinophils, neutrophils,
! 22
Student Name: Keri Bennett
and lymphocytes by stimulating beta2-adrenergic receptors in these cell types,
increasing intracellular cyclic AMP thereby activating a signaling cascade that inhibits
the release of inflammatory mediators and cytokines (Brunton, 2006)."
!In the event that an infection does begin to take hold, the inflammatory response
is triggered. The inflammatory response is non-specific, meaning that it reacts
identically to all pathogenic processes, regardless of type or origin (Porth, 2013). The
inflammatory response is a complex process involving many cellular, molecular, and
systemic processes. When foreign pathogens penetrate the epithelium, cytokines are
released. Cytokines — the mediators of inflammation — trigger mast cells located in
the interstitial fluid. These mast cells induce capillary vasodilation by the release of
histamine, which acts on capillary receptors to induce collagenase-driven restructuring
of the vascular cytoskeleton and smooth muscle relaxation. The vasodilatory effects of
histamine are responsible for swelling associated with inflammation, as the increased
porosity of the microvascular system allows blood-born immunity mediators and
plasma to accumulate in the extracellular space (Buckley, 2014). There are many
benefits to increased blood flow to the infection site: antibodies, nutrients, and oxygen
are delivered to help combat infection and repair damaged tissue, toxins are diluted,
and fibrin formation is increased. Histamine perpetuates this reaction by acting as a
positive feedback messenger, attracting more mast cells, as well as other leukocytes
and inflammatory mediators, to the site of infection (Rinewalt, 2014). "
Dendritic cells change to their phagocytosis form under the influence of
histamine and begin to envelop and digest damaged cells and bacteria. Dendritic cells
also release chemical messengers to activate helper T-lymhocytes and macrophages,
which then marginalize and initiate the specific immune response (Rosa, 2014).
! 23

Macrophages induce collagenase secretion from karatinocytes and other macrophages
by the release of interleukin-1 (IL-1), which initiates cytoskeletal rearrangement, as well
as the proliferation and migration of CD4, CD8, and mature B-cells, immunoglobulin
secretion, and proliferation of fibroblasts (Buckley, 2014)."
!Blood plasma is also involved in the inflammatory response, as it contains small
proteins (compliment) created by the liver which function as a non-specific immune
response perpetuator. Compliment proteins act as cytokines as well as exhibiting a
bactericidal effect on invading pathogens. The exact mechanism of initiation for
compliant proteins is unknown, but they are believed to be converted to their active
form by cleaving enzymes released from damaged cells or activated by inflammatory
paracrine signaling (Porth, 2013). "
!While the vascular nature of the lungs is beneficial in that it increases the
delivery of leucocytes and other immune mediators to the site of infection, increased
capillary permeability secondary to the inflammatory process also increases the risk
that bacteria will enter the bloodstream, resulting in a septic infection (Ackley, 2017).
Mrs. H’s septic infection is likely the result of pathogens from her lungs entering her
bloodstream. Her white blood cell count , although currently within normal limits, was
initially elevated at 11.3 x10^9/L. Her ANC was also initially elevated at 8,500/mm^3,
which is consistent with a pneumonial infection. "
!Sepsis is harmful to the body in two primary facets. First, bacteria traveling
through the bloodstream may colonize any organ or tissue in the body. Of primary
concern are meningeal infections, as well as infections of the heart, lungs, and the
tissue surrounding these organs. Secondly, infectious agents trigger the inflammatory
response wherever they are located in the body. While the inflammatory response is
! 24
Student Name: Keri Bennett
beneficial in localized infections, systemically, it can result in septic shock and death.
The inflammatory response decreases platelet counts, increases the risk of organ
damage (which further triggers inflammatory reactions), and may cause leukocytosis or
leukopenia (Remmick, 2017). Mrs. H is currently on a antibiotic regimen of levofloxin to
eliminate the bacteria causing her septic infection. Levofloxin. a quinolone, is
bactericidal to both Gram-positive and Gram-negative bacteria. It functions by
inhibiting the activity of DNA gyrase and topoisomerase IV, preventing the replication
and supercoiling of bacterial DNA, thus making survival of the invading organism
impossible (Skidmore-Roth, 2018). Mrs. H is responding well to antibiotic treatment;
her white blood cell count is currently within normal limits and she has been afebrile for
the last three days, indicating that the infection is being subdued. "
!Not only does the inflammatory response pose risks to the body’s circulatory
system, it also affects glucose regulation by triggering glycolysis in the liver (Porth,
2017). During her admission, Mrs. H’s glucose levels have fluctuated significantly, with
levels between 48-176mg/dL. Although these levels are not critical, and her latest
glucose reading was an “acceptable high” of 104mg/dL, the fluctuating values are
indicative of poor systemic management of glucose and insulin needs, likely as a result
of infection-related stress (Ackley, 2017). Mrs. H has been able to manage her blood
sugar using dietary interventions, without the need of medicinal assistance, however,
many patients require insulin injections to prevent ketoacidosis, a life-threatening
condition in which the inflammatory response can trigger an insulin deficiency
preventing the uptake of glucose into the cells. Without glucose accessible for
degradation, the body is forced to metabolize triglycerides and muscle tissue for
energy. Lipolysis causes serum levels of glycerol and free fatty acids (FFA’s) to rise,
acting as a substrate for the liver to initiate the gluconeogenesis stimulated by the
! 25
Student Name: Keri Bennett
excess of glucagon released by glucose-starved cells. Glucagon also stimulates the
mitochondria to convert FFAs into ketones, acidic compounds which alter blood pH,
triggering metabolic acidosis (Rinewalt, 2014). "
!Mrs. H’s elevated blood glucose levels, while not critical, are concerning in that
they may slow the rate of healing from her septic infection. Bacteria thrive in a
glucose-rich environment, increasing their rate of proliferation. High serum glucose also
alters the viscosity of the blood, slowing its progress through the circulatory system
and impeding the delivery of phagocytotic leukocytes to invading pathogens and
nutrients necessary for cells to perform regrowth and repair functions. Additionally
elevated glucose levels impede the action of leukocytes by directly altering their
functionality. Some white blood cells are unable to survive in high-glucose solutions,
while others’ signaling mechanisms are impaired, decreasing their ability to respond to
and take action against invading organisms (Batzing, 2012). In this way, something as
apparently innocuous as elevated blood glucose levels can exponentially lengthen the
healing time for infections and injuries. "
!Pathogens typically reach the alveoli in overwhelming levels if there is an
infection which has colonized the upper airway, or in the event of aspiration. Studies
have indicated that in 18% of pneumonia cases, nasal colonies of staphylococci are
present (Batzing, 2012). Patients on aspiration precautions are times more likely to
contract pneumonia infections. Dementia negatively impacts an individual’s ability to
properly chew and swallow. Given Mrs. H’s dementia diagnosis, is likely that she could
have aspirated while eating, leading to pneumonia (Etgen, 2011). She is currently
prescribed Benztropine, Rispendone, and Lamictal for the management of her
dementia symptoms. Benztropine antagonizes acetylcholine and histamine receptors,
! 26
Student Name: Keri Bennett
combating the dystonia typical of dementia-related degeneration. Lamictal is used to
regulate mood changes by inhibiting voltage-dependent sodium channels, preventing
presynaptic glutamate and aspartate release and thus reducing membrane excitability.
Rispendone is thought to antagonize dopamine D2 receptors, and serotonin 5-HT2
receptors, thus regulating mood and preventing dementia-related psychosis
(Skidmore-Roth, 2018). Mrs. H is prone to sundowners’s syndrome, a phenomenon
common among dementia patients, in which her confusion significantly increases at
night. For this reason, she takes an increased dose of Rispendone in the evenings to
help combat these effects (Erkinjuntti, 2017). "
!Because of the increased coagulation response of the blood during
inflammation, Mrs. H is at increased risk of thrombosis formation. She is already at risk
for blood clots as a result of ineffective blood movement through the upper chambers
of her heart secondary to her atrial fibrillation, and this, combined with the
compromised state of her cardiovascular system, may result in hyper-excitability of the
clotting cascade and increased thrombus formation, increasing her risk of pulmonary
embolism or stroke (Linares, 2011). Mrs. H is on Xanelto, a highly selective direct
Factor Xa inhibitor, to prevent the formation of blood clots through both the intrinic and
extrinsic pathways. Unlike Heparin, Xanelto has no effects on Factor II or on platelets,
making its effects easy to regulate and eliminating the need for diet modification while
taking the drug (Skidmore-Roth, 2018). Mrs. H continues to respond well to treatment
with Xanelto, and has not exhibited any signs of pulmonary emboli. "
!Overall, Mrs. H is responding well to treatment and is scheduled to return to her
home after her antibiotic course is completed. She will continue to take her normal
! 27

dementia medications. Increased surveillance during mealtimes has been
recommended to reduce her risk of aspiration while eating. "
