Pathogenesis and causes of hyperkalemia Pathogenesis of Causes of hyperkalemia hyperkalemia False Hyperkalemia Hemolysis Tight turnstile Thrombocytosis Leukocytosis Impaired elimination of ARF, CRF potassium Pseudohypoaldosteronism, hypoaldosteronism
, and congenital adrenal hyperplasia Medications (ACEI, ARB, NSAI) Mannitol Drugs interfering with renal potassium excretion (amiloride, spironolactone, and triamteren) Increased shift of Trauma potassium from intra Burn injury to extracellular space Rhabdomyolysis, tumorlyis, hemolysis, and after massive transfusion Acidosis Hyperkalemic periodic paralysis Hyperglisemia Succinylcholine Excessive intake ARF: Acute renal failure, CRF: Chronic renal failure, ACEI: Anjiotensin-converting-enzyme inhibitor, ARB: Anjiotensin
The combination of positive GBS in the urine and abnormal renal ultrasound supported a renal cause of the patient's hypoaldosteronism
or pseudohypoaldosteronism as the diagnosis.
These services would include neonatal/pediatric intensive care; endocrinologists to treat hypothyroidism, hypoaldosteronism
, and growth hormone deficiency; orthopedists to treat arthrogryposis; neurologists to perform neuroimaging and EEGs, and to treat microcephaly and seizures; and other specialists to handle infectious disease, pulmonology, genetics, and feeding issues.
CKD caused by diabetic nephropathy may be associated with hyporeninaemic hypoaldosteronism
, which may cause hyperkalaemia despite relatively well-preserved kidney function.
Liddle's syndrome is an autosomal dominant disorder characterized by early, and frequently severe, hypertension associated with low plasma renin activity, metabolic alkalosis due to hypokalemia, and hypoaldosteronism
6, 17) This may result in the inhibition of renin-angiotensin system and decreased aldosterone synthesis as hyporeninemic hypoaldosteronism
or hyporeninemic normoaldosteronism.
In the past, the diagnosis of primary hypoaldosteronism
leaned heavily on the presence of hypokalemia.
These findings may be attributable to hyporeninemic hypoaldosteronism
, subsequent to lead intoxication, as well as to inhibition of distal tubular Na-K-ATPase (100).
To the Editor: Hyporeninemic hypoaldosteronism
was one of the postulated mechanisms mediating hyperkalemia in the case report by Dr.
In nine subjects dehydration was caused by more than one of the following factors: insufficient water intake, vomiting, diuretic use, salt-losing renal failure, hypoaldosteronism
, lithium-induced diabetes insipidus, diarrhoea and an overshoot of diuretic treatment of heart failure.
The most prominent abnormality in type IV RTA is hyperkalemia caused by hypoaldosteronism
These presenting symptoms are similar in infants with true hypoaldosteronism
