Hartnup Disease Follow-up
- Author: Lidija Kandolf Sekulovic, MD, PhD; Chief Editor: William D James, MD more...
Further Outpatient Care
Advise patients to use protection from sunlight, to avoid other aggravating factors, to consume a high-protein diet, and to take daily supplements of nicotinic acid. In patients who are symptomatic, recommend regular follow-up examinations, depending on the severity of symptoms and the organ systems involved.
Inpatient & Outpatient Medications
Patients should continue taking daily supplements of nicotinic acid.
Deterrence/Prevention
Deterrence and prevention are as follows[24, 25] :
- Because sun exposure can exacerbate Hartnup disease, advise patients to protect themselves from sunlight.
- Because aggravating factors, such as sulfonamides and possibly emotional stress, can exacerbate Hartnup disease, advise patients to avoid these factors.
Complications
Complications are as follows[3, 22, 33] :
- Severe CNS involvement may rarely lead to death in the first years of life.
- Psychotic episodes and delirium are described in a minority of patients.
- Mild mental retardation is described in only a few patients.
- Long-lasting hypopigmentation and/or hyperpigmentation of the skin are seen with repeated exposures to sunlight, which should be avoided by using proper photoprotection.
Patient Education
Educate patients to protect themselves from sunlight, to avoid other aggravating factors, and to consume a high-protein diet.
