Which of the following is not true about
metabolic syndrome?
a) It is also called Syndrome X
b) Acanthosis and signs of hyperandrogenism may be seen
c) Type A has autoantibodies against the insulin receptor
d) Insulin resistance increases the risk of type 2 DM in patients
with PCOS
Correct Answer - C
Answer- C. Type A has autoantibodies against the insulin
receptor
It is an insulin resistance condition which comprises a spectrum of
disorders, with hyperglycemia representing one of the most readily
diagnosed features.
The metabolic syndrome, the insulin resistance syndrome, or
syndrome X are terms used to describe a constellation of metabolic
derangements that includes insulin resistance, hypertension,
dyslipidemia (decreased HDL and elevated triglycerides), central or
visceral obesity, type 2 diabetes or IGT/IFG, and accelerated cardio-
vascular disease.
Acanthosis nigricans and signs of hyperandrogenism
(hirsutism, acne, and oligomenorrhea in women) are also
common physical features.
Two distinct syndromes-

  1. type A, which affects young women and is characterized by severe
    hyperinsulinemia, obesity, and features of hyperandrogenism; and
    type A insulin resistance syndrome have an undefined defect in the
    insulin-signaling pathway.
  2. type B, which affects middle-aged women and is characterized by
    severe hyperinsulinemia, features of hyperandrogenism, and
    autoimmune disorders.
