Hypoaldosteronism is an endocrinological disorder characterized by decreased levels of the hormone aldosterone. Similarly, isolated hypoaldosteronism is the condition of having lowered aldosterone without corresponding changes in cortisol. [1] (The two hormones are both produced by the adrenals.)
Pseudohypoaldosteronism (PHA) is a condition that mimics hypoaldosteronism (presenting hyperkalemia). [1] Two major types of primary pseudohypoaldosteronism are recognized and these have major differences in etiology and presentation. [2]
Specific treatment of pseudohyperaldosteronism depends on the inciting cause. General management focuses on countering the effects of excess mineralocorticoid activity to achieve adequate blood pressure control and avoid end-organ damage and cardiovascular mortality. [1] In some cases, specific antihypertensive medications may be recommended.
If a significant change occurs across all participants the experimenter may infer that the treatment is effective. Multiple base-line experiments are most commonly used in cases where the dependent variable is not expected to return to normal after the treatment has been applied, or when medical reasons forbid the withdrawal of a treatment.
Liddle's syndrome, also called Liddle syndrome, [1] is a genetic disorder inherited in an autosomal dominant manner that is characterized by early, and frequently severe, high blood pressure associated with low plasma renin activity, metabolic alkalosis, low blood potassium, and normal to low levels of aldosterone. [1]
The production of aldosterone is regulated via the renin-angiotensin II-aldosterone system, a system composed of baroreceptors and juxtaglomerular cells. [ 7 ] [ 8 ] Changes in the homeostasis of the human body, such as osmolality are detected by the system, which causes a chain reaction that ends with the adrenal gland either increasing or ...
Since these variables were determined before the treatment decision, treatment status should not affect them. Consider the earlier merit-based scholarship example. If the outcome of interest is future grades, then we would not expect the scholarship to affect previous grades. If a discontinuity in predetermined variables is present at the ...
There are two levels of the treatment, drug, and placebo, administered to male and female patients in a double blind trial. The sex of the patient is a blocking factor accounting for treatment variability between males and females. This reduces sources of variability and thus leads to greater precision.
