Overview
Treatment
Scurvy will improve with doses of vitamin C as low as 10 mg per day though doses of around 100 mg per day are typically recommended. Most people make a full recovery within 2 weeks.
Signs and symptoms
Early symptoms are malaise and lethargy. After one to three months, patients develop shortness of breath and bone pain. Myalgias may occur because of reduced carnitine production. Other symptoms include skin changes with roughness, easy bruising and petechiae, gum disease, loosening of teeth, poor wound healing, and emotional changes (which may appear before any physica…

Pathogenesis
Vitamins are essential to the production and use of enzymes that are involved in ongoing processes throughout the human body. Ascorbic acid is needed for a variety of biosynthetic pathways, by accelerating hydroxylation and amidation reactions. In the synthesis of collagen, ascorbic acid is required as a cofactor for prolyl hydroxylase and lysyl hydroxylase. These two enzymes are responsible f…
Diagnosis
Diagnosis is typically based on physical signs, X-rays, and improvement after treatment.
Various childhood onset disorders can mimic the clinical and X-ray picture of scurvy such as:
• Rickets
• Osteochondrodysplasias especially osteogenesis imperfecta
• Blount's disease
