Steroid isolation , depending on context, is the isolation of chemical matter required for chemical structure elucidation, derivitzation or degradation chemistry, biological testing, and other research needs (generally milligrams to grams, but often more [37] or the isolation of "analytical quantities" of the substance of interest (where the focus is on identifying and quantifying the substance (for example, in biological tissue or fluid). The amount isolated depends on the analytical method, but is generally less than one microgram. [38] [ page needed ] The methods of isolation to achieve the two scales of product are distinct, but include extraction , precipitation, adsorption , chromatography , and crystallization . In both cases, the isolated substance is purified to chemical homogeneity; combined separation and analytical methods, such as LC-MS , are chosen to be "orthogonal"—achieving their separations based on distinct modes of interaction between substance and isolating matrix—to detect a single species in the pure sample. Structure determination refers to the methods to determine the chemical structure of an isolated pure steroid, using an evolving array of chemical and physical methods which have included NMR and small-molecule crystallography . [2] :10–19 Methods of analysis overlap both of the above areas, emphasizing analytical methods to determining if a steroid is present in a mixture and determining its quantity. [38]

The double-whammy of vitamin D and steroids may be particularly beneficial for cancer patients, to whom steroids are sometimes given for various complications of the disease, such as cancer spreading to the brain or bones, and for recipients of transplanted organs, whose immune systems must be inhibited to prevent them from rejecting the organs. However, Jirapongsananuruk tells WebMD that she hesitates to recommend the combination for people with asthma or allergies . Even though these conditions are characterized by an overactive or inappropriate immune response, she says, that response is mediated through different substances than the ones that are important for cancer or transplant patients. But for those individuals, she says, the combination of vitamin D and certain steroids could hold potential.

Therefore, I recommend my patients double or even triple their dose of vitamin D while they take steroids, provided they don’t have any history’ of kidney stones. No drug available today effectively treats steroid-induced osteoporosis. Here is one situation where prevention is your best treatment. Your best defense is a good dose of vitamin D. Unfortunately, many physicians don’t check vitamin D level, but immediately prescribe an anti-osteoporosis drug, such as alendronate (Fosamax), Actonel or Boniva, which doesn’t work effectively in steroid-induced osteoporosis. Beware! Next time someone puts you on a steroid, you must increase your daily dose of vitamin D. You’ll save your bones and avoid a lot of misery’ in the years to come.

The main symptoms of vitamin D overdose which are those of hypercalcemia including anorexia , nausea, and vomiting. These may be followed by polyuria , polydipsia , weakness, insomnia, nervousness, pruritus and ultimately renal failure . Furthermore, proteinuria , urinary casts , azotemia , and metastatic calcification (especially in the kidneys) may develop. [48] Other symptoms of vitamin D toxicity include mental retardation in young children, abnormal bone growth and formation, diarrhea, irritability, weight loss, and severe depression. [18] [39]
