Overview

Beriberi is a nervous system and cardiovascular ailment caused by thiamine (vitamin B1) deficiency.

Etymology

The origin of the word is from a Sinhalese phrase meaning "I cannot, I cannot", the word being doubled for emphasis.[1]

History

Christiaan Eijkman a Dutch physician and pathologist first demonstrated that beriberi is caused by poor diet led to the discovery of vitamins. Together with Sir Frederick Hopkins, he was awarded the 1929 Nobel Prize for Physiology or Medicine for the discovery.

Causes

Beriberi is caused by a lack of thiamine (vitamin B1). It is common in people whose diet consists mainly of polished white rice, which is very low in thiamine because the thiamine-bearing husk has been removed. It is also seen in chronic alcoholics with an inadequate diet, as well as being a rare side effect of gastric bypass surgery. If a baby is mainly fed on the milk of a mother who suffers from thiamine deficiency then that child may develop beriberi.

The disease has been seen traditionally in people in Asian countries (especially in the 19th century and before), due to those countries' reliance on white rice as a staple food. Beri-beri is a nutritional disorder caused by deficiency of vitamin B charactarized by damage to nerves and heart; general symptoms include loss of appetite and feeling of lassitude.

Pathophysiology

Thiamine deficiency is associated with high output heart failure due to the vasodilation that develops as a result of pyruvate and lactate accumulation [2].

Diagnosis

Symptoms

Its symptoms include weight loss, emotional disturbances, impaired sensory perception (Wernicke's encephalopathy), weakness and pain in the limbs, and periods of irregular heart rate. Edema (swelling of bodily tissues) is common. In advanced cases, the disease may cause heart failure and death. It may also increase the amount of lactic and pyruvic acids in the blood.

There are two forms of the disease: wet beriberi and dry beriberi.

  • Wet beriberi affects the heart; it is sometimes fatal, as it causes a combination of heart failure and weakening of the capillary walls (see capillary leak syndrome), which causes the peripheral tissues to become edematous.
  • Dry beriberi causes wasting and partial paralysis resulting from damaged peripheral nerves. It is also referred to as endemic neuritis.

Signs

Electrocardiogram

In some studies beriberi heart disease has been associated with a variety of ECG changes including sinus tachycardia , T wave inversion, low voltage, prolognation of the QT interval, and either prolongation or shortening of the PR interval [3] [4]. In many cases, these abnormalities revert with treatment of the thiamine deficiency. [5] [6] [7]

The mechanism by which thiamine deficiency results in ST elevation is not clear. Thiamine deficiency induces ATP depletion and it has been speculated that myocardial energy depletion may result in damage to the myocyte and thereby induce ST elevation. [8]

Treatment

Treatment is with thiamine hydrochloride, either in tablet form or injection. A rapid and dramatic recovery within hours can be made when this is administered to patients with beriberi, and their health can be transformed within an hour of administration of the treatment. Thiamine occurs naturally in unrefined cereals and fresh foods, particularly fresh meat, legumes, green vegetables, fruit, and milk.
