Overview

Beriberi should be differentiated from other causes of cardiac dysfunction (wet beriberi), peripheral neuropathy (dry beriberi), delirium (WKS), and other disorders caused by excessive alcohol drinking. However, the differential diagnosis is broad due to the non-specific symptoms of cardiac and neural involvement associated with the condition.

Differentiating Beriberi from other Diseases

Beriberi should be differentiated from other causes of cardiac dysfunction (wet beriberi), peripheral neuropathy (dry beriberi), delirium (WKS), and other disorders caused by excessive alcohol drinking. However, the differential diagnosis is broad due to the non-specific symptoms of cardiac and neural involvement associated with beriberi.[1][2][3]

Disorders Etiology Clinical Presentation Laboratory findings
Cardiomyopathy due to other causes as alcohol or DM
  • Dyspnea/Orthopnea
  • Edema
  • Syncope
  • Palpitations
Delirium and delusional disorders
  • Acute liver failure
  • Acute metabolic and electrolyte disturbances
  • Infections/sepsis
  • Toxins/drug overdose
  • Disturbed attention
  • Poor cognition
  • Impaired psychomotor activity
  • Emotional instability
Nerve entrapment disorders Chronic injuries to nerves as they pass between bones and ligaments:
  • Carpal tunnel syndrome
  • Cubital tunnel syndrome
  • Suprascapular nerve compression
  • Meralgia Paresthetica (lateral femoral cutaneous nerve)
Within the distribution of the affected nerve, the patient may complain of:
  • MRI short inversion imaging recovery (STIR) technique
Alcoholic hepatitis
  • Chronic and excessive alcohol consumption
  • Increased serum levels of ALT and AST
  • Blood picture: Leukemoid reactions (high WBCs count) may be present.
  • Liver US: Changes in liver size and dilatation of hepatic veins.
Diabetic ketoacidosis In patients with type 1 DM, exposed to:
  • Poor insulin compliance
  • Infections/sepsis
  • Stress
  • Idiopathic
  • Hyperglycemia
  • Lower PH and bicarbonate levels
  • Ketonemia and ketonuria
  • Electrolyte disturbances
  • Impaired renal function
Hyperthyroidism
  • Elevated T3 and T4 hormones
  • TSH: Reduced in 1ry and Elevated in 2ry hyperthyroidism.
  • Thyroid stimulating antibodies: Elevated only in Grave's disease
Folic acid deficiency
  • Palpitations
  • Headache
  • Fatigue
  • Poor appetite
  • Sore tongue
  • Low serum folate <2.5ng/ml
  • CBC: Macrocytic anemia and low correlated reticulocyte count
  • Peripheral blood smear: Neutrophil granulocytes and anisocytosis
