Guest guest Posted October 12, 2011 Report Share Posted October 12, 2011 Alison, I'm having a little trouble understanding what you are looking for. I tried to access your articles and 2 of them require I pay ~$4o each to read so that might be alot of the problem. If you are looking for someone who is apparently doing well on meds and DASH I probably fit that bill. Part of the problem is identifying when meds take full effect. I think Stowasser et al alluded to that and suggested testing: Laboratory Assessment During Medical Treatment For patients demonstrating bilateral aldosterone production on AVS, treatment with aldosterone antagonists usually brings about marked improvement in hypertension control.5,34,39 Only small doses (for example, 12.5–50 mg daily of spironolactone and/or 2.5–20 mg daily of amiloride) are usually required for optimal antihypertensive effect. In countries where eplerenone, a modified form of spironolactone with negligible blockade of the androgen receptor, is available, it can be used as a preferred alternative. Its widespread usage will depend on pricing. It is a little more than half as effective as spironolactone, mg for mg, so that higher doses are required. However, its greater selectivity permits this increase to adequate dosage, evidenced by renin rising into the mid-normal range, without pro-oestrogenic side-effects. At present in Australia, it is available under favourable pricing arrangements only for patients with heart failure following recent myocardial infarction. Patience is required as the full effect of each dose level takes weeks or months to be achieved. These medications correct hypokalaemia quickly in all but the most severe cases of PA, and potassium supplements should therefore usually be ceased when they are commenced, and, if not ceased, then progressively reduced (watching potassium levels) as the aldosterone antagonist has its full effect. Overtreatment with these agents can cause volume contraction with pre-renal failure, rising creatinine concentrations and potentially life-threatening hyperkalaemia.34 They should therefore be used with great caution in patients with existing renal impairment, and electrolytes and creatinine should be regularly checked. The extent to which renin levels become `unsuppressed' is a useful indication of the degree of blockade of aldosterone effect induced by any given treatment dose. While normalisation of potassium and blood pressure levels have been traditionally regarded as evidence of adequate treatment, it could be argued (given that aldosterone excess is now known to induce adverse cardiovascular effects independently of its effects on blood pressure) that the goal should be `complete' reversal of excessive aldosterone action. In this way, normalisation of renin levels may be more reassuring than simply correcting hypertension and hyperkalaemia since it indicates that the dose of mineralocorticoid antagonist is adequate to correct the sodium/volume expansion. Given that adverse cardiovascular effects of aldosterone excess appear to be dependent on sodium balance, normal renin levels would imply correction of sodium overload as well. In some patients, however, the degree to which doses can be increased in order to achieve normalisation of renin levels will be limited by tolerability. Even at spironolactone doses of 12.5–25 mg daily, side effects (such as gynaecomastia in males and menstrual irregularity in females) are not uncommon. As with the risk of hyperkalaemia and uraemia, these side effects are dose-dependent. Assessment of renin levels is also helpful in guiding changes in management for patients in whom hypertension has not yet become optimally controlled following introduction of mineralocorticoid antagonist treatment. If renin levels have already become `unsuppressed', for example, persisting hypertension is best treated by adding in or increasing the dose of other antihypertensive medications. It must be remembered that renin suppression can persist for long periods after `cure' of unilateral PA by adrenalectomy, if PA was longstanding. It may therefore also take some time for `complete' blockade of the mineralocorticoid receptor to result in renin becoming `unsuppressed'. I copied the part I will be attempting to watch and intend to talk with my PCP Monday but I'm not sure how " willing " she will be to participate in a Trial Study. Renin and aldo tests appear to be sent out to Quest Labs by the VA so there is an expense. Most other tests are done inhouse so while there is an expense it is probably less. I am already planning to ask her to check the status of LVH regression and a PFT to see changes in my lungs beside " normal " blood work. Did you look at that article and does it cover any of what you are asking? When I saw this " (given that aldosterone excess is now known to induce adverse cardiovascular effects independently of its effects on blood pressure) " I thought there might be more in the main part of the article. (I still haven't studied rhe article, my printer ran out of ink and I can't read w/o a highlighter!)
