Abstract

Background

Severe pulmonary hypertension (PH) in childhood is rare and can manifest as a life-threatening episode. We present 2 children with restrictive dietary habits with severe pulmonary hypertension secondary to scurvy and iron deficiency anemia with treatment and outcome.

Case presentation

The first case is a 2-year-old boy who presented with vomiting, diarrhea, and fever. After rehydration, he had recurrent episodes of hypotension with intermittent abdominal pain. Fluid resuscitation and inotropic medication were given. Then he suddenly collapsed. After 4-min cardiopulmonary resuscitation, his hemodynamic was stabilized. Most of the medical workup was unremarkable except for PH from the echocardiogram with estimated systolic pulmonary artery pressure (PAP) at 67 mmHg. Transient PH was diagnosed, and milrinone was prescribed. Since he had restrictive dietary habits and sclerotic rim at epiphysis in chest films, his vitamin C level was tested and reported low-level result. The second case is a 6-year-old boy with acute dyspnea, a month of low-grade fever, mild cyanosis, and a swollen left knee. Echocardiogram indicated moderate TR with estimated systolic PAP at 56 mmHg (systolic blood pressure 90 mmHg). Milrinone was given. Right cardiac catheterization showed PAP 66/38 (mean 50) mmHg and PVRi 5.7 WU.m2. Other medical conditions causing PH were excluded. With a history of improper dietary intake and clinical suspicion of scurvy, vitamin C was tested and reported undetectable level. Administration of vitamin C in both cases rapidly reversed pulmonary hypertension.

Conclusion

Pediatric PH related to vitamin C deficiency can manifest with a wide range of symptoms, varying from mild and nonspecific to severe life-threatening episodes characterized by pulmonary hypertensive crises. PH associated with scurvy is entirely reversible with appropriate investigation, diagnosis, and treatment. Our report highlights the importance of considering nutritional deficiencies as potential confounding factors in pediatric PH, emphasizing the need for comprehensive evaluation and management of these patients.

Keynote webinar | Spotlight on medication adherence

  • Webinar | 27-06-2024 | 18:00 (CEST)

Medication non-adherence is a major barrier to effective healthcare delivery; half of all patients do not follow their doctor’s recommendations or treatment plan.

Our experts explain the fundamentals with a practical discussion of how to manage non-adherence in two common scenarios: hypertension and asthma control.
