In many types of metal poisoning, there appears to be an approximately maximum allowable time interval between intoxication and the initiation of chelate therapy. When treatment is begun after this interval, the extent and irreversibility of the damage is such that the death of the organism can be assumed to follow no matter how much antidote is administered for less than toxic doses an analogous phenomenon is the occurrence of permanent damage. 

The chemical basis of this time period may not be uniform for all of the type b metals. For mercury(II) it appears to be related to the occurrence of a minimum amount of what is literally the destruction of tissue and proteins. In the case of cadmium it appears to have a different basis at least in part. Subsequent to the injection of an otherwise lethal dose of a cadmium compound there is a relatively short period when it can be complexed and removed and the animal saved. As the interval between the cadmium injection and that of the antidote (e.g. CaEDTA or CaDTPA) increases, the cadmium becomes more and more difficult to mobilize and a point is soon reached where the antidote is without effect ( 5). In the same fashion, aged cadmium deposits are apparently resistant to mobilization by EDTA ).

Loop diuretics are used in the treatment of edema associated with CHF, cirrhosis of the liver, and renal disease, including the nephrotic syndrome. These drug s are particularly useful when a greater diuretic effect is desired. Furosemide is the drug of choice when a rapid diuresis is needed or if the patient has renal insufficiency. Furosemide and torsemide are also used to treat hypertension. Ethacrynic acid is also used for the short-term management of ascites caused by a malignancy, idiopathic edema, or lymphedema. 

Amiloride (Midamor) is used in the treatment of CHF and hypertension and is often used with a thiazide diuretic. Spironolactone and triamterene are also used in tiie treatment of hypertension and edema caused by CHF, cirrhosis, and the nephrotic syndrome Amiloride, spironolactone, and triamterene are also available with hydrochlorothiazide, a thiazide diuretic that enhances tiie antihypertensive and diuretic effects of the drug combination while still conserving potassium. 

Plasma protein fractions are used to treat hypovolemic (low blood volume) shock that occurs as the result of bums, trauma, surgery, and infections, or in conditions where shock is not currently present but likely to occur. Plasma protein fractions are also used to treat hypoproteinemia (a deficiency of protein in the blood), as might be seen in patients with nephrotic syndrome and hepatic cirrhosis, as well as other diseases or disorders. As with human pooled plasma, blood type and crossmatch is not needed when plasma protein fractions are given. 

Clofibrate causes a necrotizing myopathy, particularly in patients with renal failure, nephrotic syndrome or hypothyroidism. The myopathy is painful and myokymia of unknown origin is sometimes present. The mechanism of damage is not known, but p-chlorophenol is a major metabolite of clofibrate and p-chlorophe-nol is a particularly potent uncoupler of cellular oxidative phosphorylation and disrupts the fluidity of lipid membranes. Muscle damage is repaired rapidly on the cessation of treatment. 

These studies led to the realization that proteinuria— the abnormal appearance of protein in the urine— could result not only from the enlargement of submicroscopic holes in the glomerular capillary wall, but also from the loss or neutralization of its negatively charged components. This finding has provided a new direction for research on the molecular basis for the nephrotic syndrome, a group of kidney diseases all characterized by massive proteinuria. 

Inherited defects in lipoprotein metabofism lead to the primary condition of either hypo- or hyperlipoproteinemia (Table 26-1). In addition, diseases such as diabetes mellitus, hypothyroidism, kidney disease (nephrotic syndrome), and atherosclerosis are associated with secondary abnormal hpoprotein patterns that are very similar to one or another of the primary inherited conditions. Virtually all of the primary conditions are due to a defect at a stage in hpoprotein formation, transport, or destruction (see Figures 25—, 26-5, and 26-6). Not all of the abnormafities are harmful.

Hypotonic hyponatremia with an increase in ECF is also known as dilutional hyponatremia. In this scenario, patients have an excess of total body sodium and TBW however, the excess in TBW is greater than the excess in total body sodium. Common causes include CHF, hepatic cirrhosis, and nephrotic syndrome. Treatment includes sodium and fluid restriction in conjunction with treatment of the underlying disorder—for example, salt and water restrictions are used in the setting of CHF along with loop diuretics, angiotensin-converting enzyme inhibitors, and spironolactone.15...

Administration of 3 -amino-3 -deoxy-A,ALdimethyladenosine (the amino-nucleoside of puromycin) to rats produces a nephrotic syndrome that is clinically indistinguishable from the nephrotic syndrome of unknown origin frequently observed in children [365]. Rats, monkeys, and humans are susceptible to this nephrotoxicity and susceptibility has been related to specie ability to demethylate the aminonucleoside [213]. 7V -Methyladenosine prevents development of this syndrome [365a].
