Table 3: Markers of PTH and
calcium metabolism before and after lisinopril intervention; primary HPT, without HPT, and total cohort.
Next, concerning the relationship between acid/alkaline balance and
calcium metabolism discussed in part I, the authors provide additional data:
(5) With elevated lead levels,
calcium metabolism is sometimes impaired.
Effects of ammonium chloride and sulfate on acid-base status and
calcium metabolism of dry Jersey cows.
Acid diet (high-meat protein) effects on
calcium metabolism and bone health.

Calcium metabolism in bone disease: effects of treatment with microcrystalline calcium hydroxyapatite compound and dihydrotachysterol," Journal of the Royal Society of Medicine, vol.
(1) Clinical and experimental studies have demonstrated abnormalities in
calcium metabolism at the systemic level in hypertension.
Calcium metabolism is complex, and other factors such as impaired liver and kidney function, poor nutritional status, and medications may act as confounding variables lowering calcium (17).
That is why I tend to order a comprehensive metabolic panel when disorders of
calcium metabolism are part of the differential.
These changes in PTH during pregnancy may be a response to altered
calcium metabolism. Intravascular fluid expansion and hypoalbuminemia makes less protein available to bind calcium, thus lowering total but not ionized calcium.
Additionally, secondary calcification can occur as a result of aberrations in
calcium metabolism. Petrification of the auricles is caused more often by calcification than by ossification.
The problems are divided by categories of growth, puberty, intersex, adrenal, water and electrolytes,
calcium metabolism, thyroid, and carbohydrates issues.
