11 Categories Of Rickets

Because rickets results from a metabolic disturbance, the underlying disease should be diagnosed. The causes of rickets can be classified into 11 main categories:

• Vitamin D deficiency
  • Dietary deficiency
  • Deficient endogenous synthesis
• Gastrointestinal tract disorders
  • Small intestine diseases with malabsorption
  • Partial or total gastrectomy
  • Hepatobiliary disease
  • Chronic pancreatic insufficiency
• Disorders of vitamin D metabolism
  • Hereditary - Pseudovitamin D deficiency or vitamin D dependency (types I and II)
  • Acquired
    • Use of anticonvulsants
    • Chronic renal failure
• Acidosis
  • Distal renal tubular acidosis (classic or type I)
  • Secondary forms of renal acidosis
  • Ureterosigmoidostomy
  • Drug-induced disease
    • Chronic acetazolamine ingestion
    • Chronic ammonium chloride ingestion
• Chronic renal failure
• Phosphate depletion
  • Dietary - Low phosphate intake plus ingestion of nonabsorbable antacids
    • Hereditary - X-linked hypophosphatemic rickets or adult-onset vitamin D–resistant hypophosphatemic osteomalacia
    • Acquired - Sporadic hypophosphatemic osteomalacia (phosphate diabetes), tumor-associated (oncogenous) rickets, osteomalacia, neurofibromatosis, and fibrous dysplasia
• Generalized renal tube disorders
  • Primary renal tube disorders
  • Renal tube disorders associated with systemic metabolic abnormality
    • Cystinosis
    • Glycogenosis
    • Lowe syndrome
  • Systemic disorder with associated renal disease
    • Hereditary - Inborn errors (Wilson disease, tyrosinemia) and neurofibromatosis
    • Acquired - Multiple myeloma, nephrotic syndrome, and kidney transplantation
    • Intoxication-related - Cadmium, lead, outdated tetracycline
• Primary mineralization defects
  • Hereditary
  • Acquired
    • Diphosphonate treatment
    • Fluoride treatment
• States of rapid bone formation with or without a relative defect in bone resorption
  • Postoperative hyperparathyroidism with osteitis fibrosa cystica
  • Osteopetrosis
• Defective matrix synthesis - Fibrogenesis imperfecta ossium
• Miscellaneous
  • Magnesium-dependent conditions
  • Axial osteomalacia
  • Parenteral alimentation
  • Aluminum intoxication
  • Isofosfamide treatment
