Thirteen patients with ischemic coronary heart disease purposely hyperventilated for seven minutes in order to induce hypocapnic alkalosis. One patient experienced chest pain, and one exhibited chemical signs of myocardial hypoxia. Heart rate, blood pressure and myocardial 02 consumption did not change significantly. Coronary blood flow decreased and coronary (a-v)O2 difference widened. Since t...

This report describes a novel presentation of chloride resistant metabolic alkalosis in a patient with hypercalcemia related to Multiple Myeloma (MM). A 51-year-old male with newly diagnosed MM presented with widespread skeletal involvement, calcium (Ca(+2)) of 18 mg/dL, phosphorous (PO4) of 6 mg/dL, serum bicarbonate (HCO3) of 37 mEq/L, and serum creatinine (Cr) of 2.6 mg/dL Other causes of me...

Diabetic Ketoacidosis (DKA) is the most common metabolic complications of diabetes mellitus. In some situations, other acid-base disorders coexist with DKA including metabolic alkalosis. There is several underlying etiology for the DKA with metabolic alkalosis such as extracellular volume loss secondary to vomiting or diuretics, alkali ingestion, and corticosteroid excess. We report herein the ...

We investigated the relative contributions made by the proximal and distal tubule to the correction of Cl-deplete metabolic alkalosis induced by systemic administration of NaCl. Free-flow micropuncture was used to examine net bicarbonate reabsorption in superficial proximal and distal tubules of anesthetized Munich-Wistar rats during maintenance and correction of chronic furosemide-induced Cl-d...

HUPRA syndrome is a rare autosomal recessive mitochondrial disorder caused by mutation in the SARS2 gene encoding seryl-tRNA synthetase (mtSerRS). It includes hyperuricemia, pulmonary hypertension, renal failure, and alkalosis. We present case report of boy aged 1 year 2 months with premature anemia, alkalosis diagnosed syndrome. This disease known to be progressive fatal. A genetic test reveal...

A case of Cushing's syndrome associated with chronic respiratory failure is presented. Although arterial blood gas analysis showed severe metabolic alkalosis, hypoxemia and mild hypercapnia, the patient had no evidence of pulmonary disease or neuromuscular disorder. Voluntary hyperventilation and inhalation of 100% oxygen (O2) revealed normalized arterial oxygen tension (PaO2). Following the re...

Shangraw, Robert E., and Farook Jahoor. Effect of liver disease and transplantation on urea synthesis in humans: relationship to acid-base status. Am. J. Physiol. 276 (Gastrointest. Liver Physiol. 39): G1145–G1152, 1999.—It has been suggested that hepatic urea synthesis, which consumes HCO3 , plays an important role in acid-base homeostasis. This study measured urea synthesis rate (Ra urea) dir...
