What is hypomagnesemia hypercalciuria syndrome?

What is hypomagnesemia hypercalciuria syndrome?

Abstract. Familial hypomagnesaemia with hypercalciuria and nephrocalcinosis (FHHNC) is an autosomal-recessive renal tubular disorder characterized by excessive urinary losses of magnesium and calcium, bilateral nephrocalcinosis and progressive chronic renal failure.

What is Nephrocalcinosis?

Nephrocalcinosis is characterized by the deposition of calcium in the kidney parenchyma and tubules [1]. Nephrocalcinosis may cause acute or chronic kidney injury or be incidentally detected radiographically in a patient with normal kidney function.

Is nephrocalcinosis genetic?

Nephrocalcinosis itself is not inherited . However, the condition causing nephrocalcinosis in an individual may be inherited. Some inherited conditions that may be associated with nephrocalcinosis include: Multiple endocrine neoplasia type 1 (MEN1)

Is nephrocalcinosis treatable?

Lessening of nephrocalcinosis may occur over time, but in many cases, such as when it results from primary hyperoxaluria or distal renal tubular acidosis, nephrocalcinosis is largely irreversible.

Is Bartter syndrome life threatening?

It can be very serious, even life threatening. Babies may not grow as they should in the womb, or they may be born too early. The other form is called classic. It usually starts in early childhood and isn’t as severe as the antenatal form.

Is Bartter syndrome life expectancy?

They also must be careful to maintain an adequate fluid and electrolyte balance. With treatment, prognosis in many cases is good. However, life expectancy and quality of life may be affected by complications such as growth delays, developmental problems, kidney failure and multiple hospitalizations.

What is considered severe hypomagnesemia?

Hypomagnesemia is diagnosed by measurement of serum magnesium concentration. Severe hypomagnesemia usually results in concentrations of < 1.25 mg/dL (< 0.50 mmol/L). Associated hypocalcemia and hypocalciuria are common.
