Summary
A challenging case of 11beta-hydroxylase deficiency was diagnosed in a young boy with pseudopuberty and hypertension. Careful evaluation of clinical signs and biochemical results led to the correct diagnosis.
Area of Science:
- Pediatric Endocrinology
- Biochemical Genetics
- Steroid Metabolism
Background:
- 11beta-hydroxylase deficiency is a rare cause of congenital adrenal hyperplasia, leading to hypertension and precocious puberty.
- Diagnosis can be challenging due to atypical presentations and transient biochemical alterations.
Observation:
- A 3.5-year-old boy presented with precocious pseudopuberty, hypertension, and a resolving skin rash after treatment with traditional Vietnamese medicine.
- Initial investigations revealed prepubertal androgen levels and a normal adrenal ultrasound, but an unidentified peak in the urine steroid profile.
- Discontinuation of medication led to elevated plasma androgens and 11-deoxycortisol, with the disappearance of the unknown peak and appearance of tetrahydro-11-deoxycortisol.
Findings:
- The clinical presentation and subsequent biochemical changes upon medication cessation were indicative of 11beta-hydroxylase deficiency.
- The unidentified urine steroid profile peak was likely a metabolite affected by the medication or the underlying condition.
- The detection of tetrahydro-11-deoxycortisol confirmed the enzyme deficiency.
Implications:
- This case highlights the importance of thorough clinical evaluation and reassessment of biochemical data, especially when discrepancies arise.
- Understanding the impact of traditional medications on steroid profiles is crucial for accurate diagnosis in certain populations.
- Early and accurate diagnosis of 11beta-hydroxylase deficiency is essential for appropriate management and prevention of long-term complications.

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test
In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...
Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu
Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...
