4th A in a triple A syndrome – A rare case report

K. MaheshKumar, Shriraam Mahadevan and Padmavathi Ramaswamy

Abstract

Objectives

AAA (Allgrove) syndrome is a rare genetic disorder characterized by cardinal features of adrenal insufficiency, achalasia, and alacrimia.

Case presentation

A 21 year girl of known case of Triple A syndrome was referred for the evaluation of autonomic function. She was born full term with developmental delay and abnormal gait. Esophageal manometry study by pneumatic balloon dilatation revealed the presence of achalasia cardia. She had signs of peripheral neuropathy and had episodes of fainting and suspected orthostatic hypotension. Cardiovascular autonomic function and heart rate variability tests were conducted as per Ewing protocol, revealed that the patient had sympathovagal imbalance and sympathetic dominance.

Conclusions

The presence of autonomic dysfunction adds the 4th A to the Triple A syndrome (Adrenal insufficiency, Achalasia, Alacrimia and Autonomic dysfunction). Noninvasive autonomic function tests are recommended for Triple A syndrome patients to reduce the morbidity associated with autonomic dysfunction.
