MEGALOBLASTIC – FOLATE DEFICIENCY - Nursing Case Study

Pathophysiology

• Primary mechanism: Folate deficiency impairs DNA synthesis, leading to ineffective erythropoiesis. Folate is crucial for the synthesis of thymidine, a nucleotide necessary for DNA replication. Without sufficient folate, cells cannot divide properly, resulting in the formation of large, immature red blood cells called megaloblasts.

• Secondary mechanism: Accumulation of homocysteine occurs due to inadequate folate, as it is needed for the conversion of homocysteine to methionine. Elevated homocysteine levels can contribute to endothelial damage and increase cardiovascular risk.

• Key complication: The presence of megaloblasts in the bone marrow and their premature destruction (ineffective erythropoiesis) lead to anemia, characterized by fatigue, pallor, and weakness, due to insufficient oxygen delivery to tissues.

Section 1

New Diagnostic Results:

As the investigation into the patient's symptoms continued, further diagnostic tests were conducted to confirm the suspected folate deficiency and assess its impact on the patient's health. A complete blood count (CBC) revealed macrocytic anemia, characterized by a low hemoglobin level of 8.5 g/dL (normal range: 12-16 g/dL for females) and a mean corpuscular volume (MCV) of 105 fL (normal range: 80-100 fL), indicating enlarged red blood cells. A serum folate test showed a significantly reduced level of 2 ng/mL (normal range: 4-20 ng/mL), confirming folate deficiency as the primary cause of her megaloblastic anemia. Additionally, elevated homocysteine levels were noted at 18 µmol/L (normal range: 5-15 µmol/L), supporting the secondary mechanism of endothelial damage risk.

In conjunction with these laboratory results, a peripheral blood smear was performed and revealed hypersegmented neutrophils, a hallmark of megaloblastic changes, further substantiating the diagnosis. The patient’s liver function tests showed slight elevations in liver enzymes, likely related to her history of alcohol use disorder, which may also contribute to folate malabsorption. Given these findings, the clinical team recognized the need to address not only the folate deficiency but also to mitigate the potential cardiovascular risks posed by the elevated homocysteine levels. These results prompted the healthcare team to consider the initiation of folate supplementation and dietary modifications, alongside counseling for alcohol cessation, to prevent further complications and optimize the patient's recovery.

Section 2

As the patient began treatment with folate supplementation and dietary modifications, her initial response appeared promising, with a gradual improvement in her fatigue levels and resolution of some gastrointestinal symptoms. However, during a routine follow-up appointment two weeks into her treatment, the patient reported new-onset shortness of breath and a persistent headache. Upon examination, her vital signs revealed a blood pressure of 150/95 mmHg, heart rate of 110 beats per minute, and oxygen saturation of 92% on room air, indicating potential cardiovascular strain.

Concerned about the changes in her status, the healthcare team initiated further diagnostic evaluations. A repeat CBC showed a slight improvement in hemoglobin levels to 9.2 g/dL, yet her MCV remained elevated at 103 fL. Additionally, a chest X-ray was ordered, revealing mild cardiomegaly and possible early signs of pulmonary congestion. An echocardiogram confirmed left ventricular hypertrophy, suggesting a possible link between her elevated homocysteine levels and the development of hypertensive heart changes.

These findings prompted a reevaluation of the patient's management plan. The clinical team recognized the need for more aggressive control of her blood pressure and further reduction of homocysteine levels to prevent progression of cardiovascular complications. The decision was made to introduce antihypertensive therapy alongside continued folate supplementation. Furthermore, a referral to a cardiologist for specialized management and close monitoring of her cardiovascular status was considered essential to optimize her care and prevent further deterioration.

Section 3

In the weeks following the introduction of antihypertensive therapy and continued folate supplementation, the patient initially showed signs of stabilization. Her blood pressure began to normalize, with readings averaging around 130/85 mmHg, and her heart rate settled to 90 beats per minute. However, during a subsequent follow-up, the patient reported experiencing increased episodes of fatigue and dizziness, especially upon standing. Her oxygen saturation remained stable at 94% on room air, but her blood pressure readings occasionally dipped to 110/70 mmHg, suggesting possible overcorrection of her hypertension and orthostatic hypotension.

A comprehensive metabolic panel revealed a slight decrease in serum sodium levels at 134 mmol/L, raising concerns about potential electrolyte imbalances secondary to the diuretic component of her antihypertensive regimen. Given these developments, the healthcare team deliberated on adjusting her medication to achieve a balance between effective blood pressure control and minimizing side effects. The patient's folate levels were reassessed, showing a substantial improvement, yet her homocysteine levels remained marginally elevated at 15 µmol/L. This indicated the need for further dietary adjustments and possibly the introduction of vitamin B12 supplementation, considering the interrelationship between folate, vitamin B12, and homocysteine metabolism.

These findings highlighted the complexity of her case, necessitating a nuanced approach to her management plan. The clinical team decided to modify her antihypertensive regimen to reduce the diuretic dose while maintaining adequate blood pressure control. Additionally, the patient was counseled on increasing her dietary intake of vitamin B12-rich foods, and a low-dose vitamin B12 supplement was introduced. The multidisciplinary team, including the cardiologist, continued to monitor her closely, focusing on optimizing her cardiovascular and hematological status while preventing further complications.

Section 4

In the following weeks, the patient's response to the adjusted antihypertensive regimen and vitamin B12 supplementation was closely monitored. Initially, her symptoms of fatigue and dizziness seemed to abate, suggesting a positive response to the intervention. Her blood pressure readings stabilized, averaging around 120/75 mmHg, and her heart rate remained steady at 88 beats per minute. However, during a routine follow-up visit, she reported new symptoms of numbness and tingling in her extremities, primarily affecting her hands and feet. These symptoms raised concerns about potential peripheral neuropathy, which could be related to vitamin B12 deficiency, despite the recent dietary and supplemental adjustments.

A repeat comprehensive metabolic panel and complete blood count were performed to further investigate these symptoms. The results revealed a slight decrease in her hemoglobin levels to 11.2 g/dL, down from her previous level of 12.0 g/dL, while her mean corpuscular volume (MCV) remained elevated at 102 fL, consistent with macrocytic anemia. Her serum vitamin B12 levels were at the lower end of normal at 210 pg/mL, despite supplementation, suggesting possible malabsorption issues. Her folate levels were within the normal range, reflecting the effectiveness of her previous supplementation. These findings prompted the healthcare team to consider the possibility of an underlying gastrointestinal issue impacting vitamin B12 absorption, such as pernicious anemia or another malabsorptive disorder.

Given this new complication, the clinical team decided to initiate further diagnostic testing, including intrinsic factor antibody testing and a Schilling test, to better evaluate her vitamin B12 absorption capabilities. The patient was also referred to a gastroenterologist for an endoscopic examination to rule out any structural or functional causes of malabsorption. In the meantime, her vitamin B12 supplementation was adjusted to include intramuscular injections, which bypass the gastrointestinal tract, in hopes of rapidly correcting the deficiency and alleviating her neurological symptoms. The team remained vigilant, prepared to adapt her management plan as new information emerged, ensuring comprehensive care for her multifaceted condition.

Section 5

In the weeks following the initiation of intramuscular vitamin B12 injections, the patient returned for a follow-up appointment. During the initial assessment, the patient reported a moderate improvement in the numbness and tingling sensations in her extremities, though these symptoms had not completely resolved. She also noted experiencing intermittent abdominal discomfort and occasional bloating, which she had not previously reported. Vital signs remained stable, with a blood pressure of 122/76 mmHg and a heart rate of 85 beats per minute. However, a physical examination revealed a slight pallor and glossitis, which was consistent with ongoing anemia despite the interventions.

New diagnostic results from the intrinsic factor antibody testing came back positive, strongly suggesting pernicious anemia as the underlying cause of her vitamin B12 deficiency. The Schilling test confirmed impaired absorption of oral vitamin B12, aligning with the suspected diagnosis. Further, the endoscopic examination performed by the gastroenterologist revealed mild atrophic gastritis, which could contribute to her symptoms and malabsorption issues.

With these findings, the healthcare team faced the challenge of addressing both the hematological and gastrointestinal aspects of her condition. The positive response to intramuscular vitamin B12 injections was encouraging, indicating effective absorption through this route. However, the patient's new gastrointestinal symptoms prompted a re-evaluation of her dietary and medication regimen to optimize her comfort and nutritional status. The team considered adding a proton pump inhibitor to manage her gastritis, while maintaining regular B12 injections to prevent recurrence of neurological symptoms. As the team prepared to adjust her care plan, they remained vigilant for any further complications that could arise from her complex condition, emphasizing the importance of multidisciplinary collaboration in her ongoing management.
