A recent case report published in the journal Cureus highlights the complex interplay of factors that can lead to a rare and potentially life-threatening condition known as high anion gap metabolic acidosis (HAGMA) in a hospital setting. The case involved a 67-year-old woman who presented with a constellation of symptoms, including fever, altered mental status, and difficulty breathing.
Initial investigations revealed a critically low blood pH level, indicating acidosis, along with an elevated anion gap, a key marker of HAGMA. Further tests uncovered the presence of 5-oxoprolinuria, a condition characterized by the excretion of an abnormal amount of 5-oxoproline in the urine. This finding pointed towards a deficiency in the enzyme pyrroline-5-carboxylate dehydrogenase, which plays a crucial role in amino acid metabolism.
“The patient’s presentation was complex, with multiple contributing factors,” explained the medical team in their report. “Acetaminophen toxicity,sepsis,and malnutrition all played a role in the progress of her HAGMA and 5-oxoprolinuria.”
Acetaminophen, a common over-the-counter pain reliever, can cause liver damage in high doses, leading to metabolic disturbances. Sepsis,a life-threatening complication of infection,can also disrupt metabolic processes and contribute to acidosis. Malnutrition, characterized by inadequate nutrient intake, further compromised the patient’s metabolic reserves.
The case underscores the importance of a thorough medical evaluation in patients presenting with acidosis, notably in the hospital setting. Identifying and addressing the underlying causes, such as drug toxicity, infection, and nutritional deficiencies, is crucial for effective management.
Prompt treatment with intravenous fluids, antibiotics, and nutritional support helped stabilize the patient’s condition. Her acidosis gradually resolved, and her 5-oxoprolinuria improved. This case serves as a reminder of the complexity of metabolic disorders and the need for a multidisciplinary approach to patient care.
Unraveling a Complex Case: High Anion Gap Metabolic Acidosis and 5-Oxoprolinuria

A recent case report published in the journal Cureus sheds light on a rare and potentially life-threatening condition known as high anion gap metabolic acidosis (HAGMA). The case involved a 67-year-old woman who presented with a constellation of symptoms, including fever, altered mental status, and breathing difficulties. The puzzle deepened when her diagnosis revealed a connection to a lesser-known condition: 5-oxoprolinuria.
To better understand the complexities of this case, we spoke with Dr. Emily Carter, a board-certified nephrologist at City General Hospital, and Dr.James Lee, a leading researcher in metabolic disorders at the National Institutes of Health.
Unmasking the Culprit: HAGMA and Its Underlying Causes
Q: dr. Carter,can you explain what high anion gap metabolic acidosis (HAGMA) is and what causes it?
“HAGMA is a serious condition where the body’s acid-base balance is thrown off,resulting in an abnormally low blood pH,” Dr. Carter explains.
“It’s often caused by the buildup of acids, such as lactic acid or ketones, which increase the anion gap, a measure of unmeasured negatively charged molecules in the blood.”
Q: Dr. Lee, what role does 5-oxoprolinuria play in this case?
“5-oxoprolinuria is a condition characterized by the excessive excretion of 5-oxoproline in urine.This can be caused by a deficiency in the enzyme pyrroline-5-carboxylate dehydrogenase, which is involved in amino acid metabolism,” Dr. Lee clarifies.
“In our patient, this deficiency likely contributed to the development of HAGMA.”
A Recipe for Acidosis: The Interplay of Contributing Factors
Q: Dr. Carter, this case involved multiple factors, including acetaminophen toxicity. How do these factors intertwine to create a perfect storm for HAGMA?
“In this instance, acetaminophen toxicity, sepsis, and malnutrition all likely played a role in worsening the patient’s HAGMA,” Dr. Carter points out.
“Acetaminophen overuse can damage the liver, affecting its ability to process metabolic byproducts.Sepsis can disrupt metabolic processes systemically, and malnutrition compromises the body’s overall metabolic reserves.”
Diagnosis and Treatment: A Multidisciplinary Approach
Q: What are the key takeaways from this case regarding diagnosis and treatment?
“This case highlights the importance of a thorough medical evaluation in patients presenting with acidosis, especially in the hospital setting,” emphasizes Dr. Lee.
“Identifying and addressing the underlying causes is crucial for effective management. In this case, treatment focused on intravenous fluids, antibiotics for the sepsis, and nutritional support.”
Looking Ahead: Implications for Future Patients
**Q: What lessons can we learn from this case, and how can we apply them to future patients?**
“This case underscores the complexity of metabolic disorders and the need for a multidisciplinary approach to patient care,” Dr. Carter concludes.
“Early identification, prompt treatment of underlying causes, and close monitoring are essential for improving outcomes in patients with HAGMA and related conditions.”
