42 Possible Causes for Pseudohyponatremia

Show results in: Magyar

  • Multiple Myeloma

    Of 183 patients with multiple myeloma treated with melphalan, 43% demonstrated an objective response. Of the evaluable cases, 70% of the patients responded to combination therapy with melphalan and prednisone, 35% to intermittent melphalan therapy, and 19% to daily melphalan therapy. Symptomatic manifestations of[…][]

  • Hypertriglyceridemia

    Hyponatremia is a frequent finding and reflects pseudohyponatremia secondary to hyperlipidemia.[] In particular, measurements of amylase and sodium may be artificially low (pseudohyponatremia; Melnick 2016 ).[]

  • Hyponatremia

    Herein, we describe the most common pitfalls in the evaluation of the hyponatremic patient, such as failure to exclude pseudohyponatremia or hypertonic hyponatremia (related[] Hyponatremia in patients with normal osmolality (isotonicity) suggests the presence of pseudohyponatremia, for which corrective action is not required.[] In addition to pseudohyponatremia, spurious hyponatremia can occur if a sample is contaminated with intravenous fluid containing sodium at less than half that of serum, such[]

  • Hyperproteinemia

    We hypothesized that IVIG therapy may result in hyperproteinemia, increased serum viscosity, and pseudohyponatremia.[] Hyponatremia can be broadly divided into two fundamental categories: "true hyponatremia" (in which the serum sodium concentration is truly less than normal), or "pseudohyponatremia[] Otherwise you may be explaining pseudohyponatremia to a concerned physician.[]

  • Hypercholesterolemia

    This case shows that extreme hypercholesterolemia from elevation of lipoprotein-X particles in cholestasis can be a rare cause of pseudohyponatremia.[] KEYWORDS: Cholestasis; Hypercholesterolemia; Hyponatremia; Lipoprotein-X (LpX); Primary biliary cirrhosis (PBC); Pseudohypokalemia; Pseudohyponatremia[] Abstract Pseudohyponatremia has been reported in association with severe hypertriglyceridemia and hyperparaproteinemia, but its association with severe hypercholesterolemia[]

  • Electrolyte Imbalance

    Pseudohyponatremia occurs when too much water is drawn into the blood; it is commonly seen in people with hypoglycemia (low blood sugar).[]

  • Hyposmolality

    Hyperproteinemia of sufficient magnitude to induce pseudohyponatremia commonly is due to coexisting multiple myeloma.[] […] less common condition of hyponatremia associated with normal serum osmolality is seen in patients with extreme hyperlipidemia and hyperproteinemia which is also known as pseudohyponatremia[] Hyperlipidemia that is severe enough to produce pseudohyponatremia almost always is accompanied by a notably lipemic appearance of the serum sample.[]

  • Psychogenic Polydipsia
