Initial Post Week 1 Scenario A 10-year-old male patient

A 10-year-old male patient presents to your clinic with a nose bleed that has been actively bleeding for more than two hours. The patient states he was running around the corner of his house and ran into his sibling and his nose began to bleed. The bleeding is not profuse, but is a steady stream and has not responded to applied pressure externally or to the application of ice externally. The patient denies any internal attempts to stop the flow of blood. Demographic information noted that the patient lived at home with both parents and his two younger sisters, had no previous medical history and neither parent had any significant medical history.

During additional questioning about medical history, the patient’s parents revealed that the patient has always been a “bleeder.” Upon further questioning for clarification, the patient’s parents explained that the patient has always bled more than his siblings even with the smallest of injuries. After exam and further testing, you find that the patient has Hemophilia A. The patient’s parents are confused and have many questions concerning how the patient developed this disorder and why it was not discovered before.

The patient factor I chose to discuss is gender. An individual’s gender can have many influences on different disorders, specifically those caused by genetic factors. Hemophilia is one of those disorders. Hemophilia is an X-linked recessive trait disorder that affects males but not the female carriers (Hammer & McPhee, 2019). In females, the X chromosome received from the mother has the recessive allele, but the X chromosome from the father has a normal allele essentially cancelling out the recessive trait (Huether & McCance, 2017). Because males only have one X chromosome and Y chromosomes do not carry a normal allele, males are the ones affected by the recessive trait.

The severity is related to the exact amount of either factor VIII (type A) or factor IX (type B) that an individual is lacking. Females have at least 50% of the required amount of either factor and therefore are unaffected by the deficiency (Hammer & McPhee, 2019). This disorder is also affected by the quantity of the factor available in their bodies. Hemophilia is one of the disorders that is labeled as a quantitative disorder because the severity of the disorder is related to the level of deficiency in each individual rather than a complete lack of the factor (Hammer & McPhee, 2019). Most severe cases of either Hemophilia A or B are diagnosed in the neonatal period; however, less severe cases may take years to be diagnosed (Lee, Berntorp, Hoots, & Tuddenham, 2014).

The pathophysiology of Hemophilia is related to the lack of clotting factors needed to stop bleeding once it occurs. Clotting factors are proteins that are found throughout the vascular system in an inactive form. When there is damage to vascular bodies, bleeding occurs and the clotting factors are then exposed to a substance called thromboplastin released by the damaged tissue. This interaction of thromboplastin and the clotting factors cause the formation of a clot to block the damaged areas and prevent further loss of blood into the surrounding tissue or out of the body depending on the nature of the injury (Huether & McCance, 2017). When there is a decrease or a lack of these clotting factors, the body is unable to form clots that will prevent continued bleeding from injury.

For those suffering from Hemophilia, the lack of clotting factors VIII or IX are the causative factors. In the scenario described above, the reason that the child’s hemophilia was not detected prior to this injury was related to several potential factors. The first factor is the likelihood that the child had a very mild form of the disorder related to the quantitative level of his factor VIII deficiency. Second, because females are only carriers, unless he had male relatives who had been previously diagnosed, there would be no suspicion that this disease was a concern for this patient. A thorough history in these cases can help point you in the right directions for testing and eventual diagnosis.

Hemophilia A is a genetic disorder characterized by the deficiency of clotting factor VIII, leading to an inability to stop bleeding effectively. In understanding this disorder, various factors come into play, notably gender, which significantly influences its manifestation and diagnosis. Hemophilia is classified as an X-linked recessive trait, predominantly affecting males due to their unique chromosomal configuration. Males possess one X and one Y chromosome, whereas females have two X chromosomes. This chromosomal disparity explains why hemophilia primarily affects males, who express the disorder if they inherit the recessive allele on their single X chromosome (Iorio et al., 2017). Females, on the other hand, can be carriers without expressing symptoms since they have a second X chromosome that can provide a normal allele to mitigate the effects of the disorder (Huether & McCance, 2017).

The expression of hemophilia is influenced by the levels of factor VIII in the blood. Males can exhibit different severities of hemophilia A depending on the amount of functioning factor present. This quantitative nature of the disorder means that some boys may experience severe bleeding problems, while others may have milder symptoms that do not become apparent until a significant injury occurs (Lee et al., 2014). As is evident in the case described, this child's history of being a “bleeder” may have been overlooked due to the lack of severe episodes earlier in life, which could have prompted earlier diagnosis.

Clinically, hemophilia A presents with symptoms such as easy bruising, prolonged bleeding from cuts, and excessive bleeding after surgery or injury. The natural response to injury involves a cascade of events triggered by exposure of tissue factors that activate platelets and clotting factors to form a clot (Kumar & Clark, 2016). In the case of hemophilia A, the lack of factor VIII means that this cascade is incomplete, and the clot formation is impaired. This leads to prolonged bleeding episodes that can be alarming for parents and caregivers, especially when they occur with seemingly minor injuries.

The androgens also have a role. Male individuals, upon entering puberty, experience increases in testosterone levels, which can influence clotting factor levels and bleeding tendencies. Studies have shown that testosterone may have a positive impact on the levels of certain coagulation factors, which may theoretically buffer some of the bleeding risks in males during this time of hormonal change (Baker & Smith, 2015). Understanding the interplay between gender and bleeding disorders like hemophilia is essential for effective management and counseling of affected families.

The diagnosis of hemophilia is typically established through laboratory tests that measure the levels of clotting factors in the blood. In the case of mild hemophilia A, factor VIII levels can be marginally low, thus delaying diagnosis until something triggers significant bleeding. If an affected individual is positively identified, it is crucial for the family to receive counseling regarding the genetic implications of hemophilia, especially concerning future children (Dimichele, 2016). With X-linked disorders, there exists a 50% chance that a male child will be affected if the mother is a carrier, while female children would have a 50% chance of being carriers themselves.

In conclusion, it is essential to appreciate the gender dynamics at play in the understanding and clinical management of hemophilia A. As seen in the presented case, the ignorance surrounding initial symptoms of the disorder can lead to delayed diagnosis and potentially life-threatening situations for male patients. Medical professionals must ensure thorough histories are taken and genetic counseling provided to optimize care for families affected by this disorder. Awareness and education about hemophilia, its inheritance patterns, symptoms, and treatment options are vital to improve outcomes for those at risk.
