What dose of biotin treats biotinidase deficiency?

Standard biotin dose is 5-10 mg/day orally for profound deficiency (<10% activity); partial deficiency (<30% activity) may require lower doses or monitoring without treatment.

What neurological complications occur without treatment?

Untreated profound biotinidase deficiency causes seizures, hypotonia, ataxia, developmental delay, sensorineural hearing loss, and vision problems (optic atrophy).

Are neurological complications reversible with biotin treatment?

Seizures and metabolic findings are reversible; however, sensorineural hearing loss and optic atrophy established before treatment may be permanent.

What organic acids are elevated in biotinidase deficiency?

3-hydroxyisovaleric acid, methylcitrate, 3-methylcrotonylglycine, and 3-hydroxypropionate are elevated; plasma biotin levels are low; biotinylated carboxylases are deficient.

Is biotin treatment needed lifelong?

Yes, biotin supplementation is required lifelong since the enzymatic defect is permanent; dose may need adjustment during illness or growth spurts when requirements increase.

Biotinidase Deficiency Treatment Monitor

Monitors biotinidase deficiency treatment response with biotin supplementation dosing, plasma biotin levels, and assessment of neurological, auditory, visual, and dermatological complications.
