Question

Which of the following are indications of Renal rickets (related to old age)?
A) Vitamin D deficiency
B) Osteoporosis
C) Chronic kidney disease
D) Both B and C

Answer 1

The word renal relates to “kidney” and the word rickets is related to “bones”. We should always look for the naming of the disease to get the hint to attempt the question.

Complete answer:

1. Deficiency of Vitamin D can lead to a loss of bone density.Severe vitamin D deficiency can also lead to other diseases. The deficiency can cause rickets but only in children. Rickets is a rare disease that causes the bones to become soft and bend.
2. Renal rickets is a bone disease that occurs when your kidneys fail to maintain the proper levels of calcium and phosphorus in your blood. Renal rickets occur due to the renal system not functioning properly and thus resulting in insufficiency caused because of the effects of osteoporosis.
3. Chronic kidney disease can also contribute to renal rickets in old age as renal rickets may also be caused by kidney disorders that occur due to accumulation of acid in the body due to a failure of the kidneys to appropriately acidify the urine (Renal tubular acidosis).
4. As both osteoporosis and chronic kidney disease contribute to renal rickets. The answer is both B and C

Additional information: Renal rickets initially manifest at the distal forearm, knee, and costochondral junctions.This disease is also known as Renal osteodystrophy. The symptoms include bone pain, joint pain, bone deformation, bone fracture.

Thus, the correct answer is option D (Both B and C).

Note: Multiple conditions in the body can cause a major disease/condition, especially in old age. Other comorbidities (the presence of one or more additional conditions often co-occurring with a primary condition.)
