NURS 6501: Advanced Pathophysiology Walden University full course – Week 1 discussion post
Alterations in Cellular Processes
Alterations of cellular responses are caused by multiple changes that
occur within the cell due to the environmental stressors. Different diseases can cause alterations of cellular responses that can lead to abnormal changes in the normal response processes, and it can be showed as signs and symptoms. A case study indicates a 16-year-old boy who visit a clinic with chief complaint of sore throat for 3 days presenting in with multiple symptoms. The bacteria that were involved in the disease is called Pharyngitis. Unfortunately, he experiences a severe allergic reaction after the administration of amoxicillin 500 mg. It is a fact genetics, presentation of specific symptoms and the impact of age factor need to be considered.
Role of genetics
Research shows that Streptococcus group A bacteria and is often linked
to genetics and it is the major cause of sore throat that were experienced by most young children. Genetic variations taking place at the HLA region are linked to the recurrent nature of sore throat. More so, some specific variations of the gene are evident during genetic testing and are associated with the immune systems interaction with pathogens. Study indicates that many patients become more susceptible to sore throat following the genetic changes that causes variations due to insufficient responses of the antibody responses against the bacteria.
Why the patient presents with the specific symptoms
The alteration of normal responses within the cells of the body can cause the signs and symptoms of diseases. For example, the invasion of Streptococcus group A bacteria in the body can result to secretion of pus, redness, inflammation of the throat. Clinical manifestations are thus associated with the pharynx colonialization by the fibronectin-binding proteins of Streptococcus pyogenes (Soderholm, Barnett, Sweet & Walker, 2018). However, during treatment with amoxicillin some patient experience sign and symptom that includes difficulty breathing, tachycardia, swelling of lips, vomiting, and wheezing and it was due to allergic responses to the antibiotics.
Physiologic response and cells involved in the process
The physiologic responses for this patient include redness in the posterior pharynx with white exudate on tonsils that are enlarged to 3 plus. The sign will include positive anterior and a posterior cervical adenopathy. The adaptive and innate responses are responsible for the physiologic responses as they create a defense mechanism to fight the infection strep test, the patient turned out positive of Streptococcus group A bacteria. The immune cells involved in this allergic reaction are Helper T cells of type 1, 2, and 17.This allergic reaction is a type I hypersensitivity reaction. The drug is presented to these T cells through the dendritic cells. The antigen binds to TCR receptors on the T cells and activates these immune cells (McCance & Huether, 2019).
How age factor would change the response
Study indicates that people ‘s age can affect the risks of contracting diseases. It includes how some illnesses are more common in the young persons while others are common among the elderly. An increase in rate of pharyngitis is very common in children of between 5 to 15 years old. According to Campbell et al. (2018), a 5 to 10% risk of sore throat infection exists among the adults regardless of the already established strong immune system. Safe pharmacologic treatment of sore throat patients should thus be guided by the age of the patient to prevent adverse reactions and allergies.

In addition to you points, Allergic reactions to amoxicillin are very common occurrences in the pediatric age group. Amoxicillin is a commonly prescribed antibiotic for treatment of community-acquired bacterial infections in children. Given that it is a first-line treatment for otitis media and sinusitis, and given the high frequency of viral-induced exanthemas including hives in this age group (nih.gov).
True allergic reactions to amoxicillin are mediated by the immune system and are classified into immediate (developing within 30 to 60 minutes of drug ingestion) or non-immediate (beyond 1 hour of ingestion) type reactions (nih.gov). Immediate reactions may range in severity from eruptions limited to the skin (hives/angioedema) to reactions involving more than one organ system or hypotension (that is, anaphylaxis). Non-immediate reactions occur more than 1 hour after ingestion of antibiotic and usually last several days.
In conclusion, many different types of cells are involved in the inflammatory process including mast cells, endothelial cells, platelets, phagocytes (neutrophils, eosinophils, monocytes and macrophages, dendritic cells), natural killer (NK) cells, and lymphocytes (McCance & Huether, 2019).

The symptoms represent pharyngitis caused by viruses, bacteria, chemicals, or even gastroesophageal reflux disease. In this case, the culprit is a streptococcal infection with a low-grade fever, which would indicate pharyngitis. The boy experienced symptoms because of his illness and was treated for the condition, resulting in an anaphylactic reaction. I listed an article that I came across that I thought might interest you regarding clinical and experimental immunology.
The sixteen-year-old boy had an anaphylactic reaction to the Amoxicillin prescribed to treat pharyngitis, which resulted in swelling of the lips and tongue, resulting in audible wheezes from the airway constricting. I read an article that noted that allergic diseases affect pubescent males more than females. The prevalence of many diseases in the female gender and the male gender points to testosterone, which limits immune function, whereas estrogen and progesterone support it (Demartinis et al., 2020, p.4). I had a response from a peer that contradicted this article. I have included that information in my references for you. I also listed an article from the CDC relevant to anaphylactic reactions even though the article was written for COVID-19 vaccinations. “Genes, hormones, environmental and immunological factors affect sex disparities associated with the development and control of allergic diseases, while they more rarely are considered and reported regarding their differences related to social, psychological, cultural, economic, and employment aspects” (Demartinis et al., 2020, p.1).

Hello XX
It is true that cell environment stressors cause alterations within the cell and different diseases cause alterations as cells respond to change. Ultimately, the processes of reacting to change would be expressed as symptoms as evident in the child in the case study. Pharyngitis, caused by bacteria and treatable by administering Amoxicillin 500 mg would involve different processes and responses. Consideration of genetic and age factors become critical in analyzing the symptomatic expressions and the outcome upon administration of the medication (Mccance & Huether, 2018).
I believe that association of streptococcus Group A (SGA) bacteria with genetic variations at the HLA region define the susceptibility of children to SGA (Medline Plus, 2021). This is expressed through symptoms like sore throat as a result of inflammatory reactions that links to the immune cell interaction with the perceived pathogen. Patients who have an alteration of the gene are not capable of producing g sufficient antibodies in response to the pathogen (Mccance & Huether, 2018). This leads to a recurrence and the need for medication. Inflammatory mediators triggered upon detection of pathogens may lead to redness, heat, swelling and pain.
Type-1 hypersensitive reaction involving immune cells such as the Helper-T cell results to the symptoms evident by the patient. Additionally, I agree that research indicate that there is a relation between age and susceptibility to disease. Some diseases are common among the elderly while some are common among children. It is true that pharyngitis is most common among children between age 5 and 15 (Mccance & Huether, 2018). Adults may also present with sore throat regardless of attaining remarkable immunity. Treatment require consideration of age in order to administer the correct doses and to prevent cases of adverse reactions.

Week 1: Cellular Processes and the Genetic Environment
One of the more common biology analogies refers to cells as the “building blocks” of life. This rightfully places an emphasis on understanding cells, cellular behavior, and the impact of the environment in which they function.
Such an understanding helps explain how healthy cell activity contributes to good health. Just as importantly, it helps explain how breakdowns in cellular behavior and alterations to cells lead to health issues.
This week, you examine cellular processes that are subject to alterations that can lead to disease. You evaluate the genetic environments within which these processes exist as well as the impact these environments have on disease.
Learning Objectives
Students will:
- Evaluate cellular processes and alterations within cellular processes
- Evaluate the impact of the genetic environment on disease

With a place squarely in the spotlight for patients diagnosed with all manner of disease, APRNs must demonstrate not only support and compassion, but expertise to guide patients’ understanding of diagnoses and treatment plans.
This expertise goes beyond an understanding of disease and sciences, such as cellular pathophysiology. APRNs must become experts in their patients, understanding their medical backgrounds, pertinent characteristics, and other variables that can be factors in their diagnoses and treatments.
This week, you examine alterations in the immune system and the resultant disease processes. You consider patient characteristics, including racial and ethnic variables, and the impact they have on altered physiology.
Learning Objectives
Students will:
- Evaluate cellular processes and alterations within cellular processes
- Analyze alterations in the immune system that result in disease processes
- Identify racial/ethnic variables that may impact physiological functioning
- Evaluate the impact of patient characteristics on disorders and altered physiology

Module 2 Assignment: Case Study Analysis
An understanding of the cardiovascular and respiratory systems is a critically important component of disease diagnosis and treatment. This importance is magnified by the fact that these two systems work so closely together. A variety of factors and circumstances that impact the emergence and severity of issues in one system can have a role in the performance of the other.
Effective disease analysis often requires an understanding that goes beyond these systems and their capacity to work together. The impact of patient characteristics, as well as racial and ethnic variables, can also have an important impact.
