AACE Clin Case Rep 2021 Jul-Aug;7(4):239-242. Epub 2020 Nov 28.

Department of Internal Medicine, Wellstar Atlanta Medical Center, Atlanta, Georgia.

Objective: To create awareness among health care professionals and nurses regarding interference with point-of-care (POC) blood glucose (BG) meter by high-dose intravenous vitamin C and other potential substances. We report a case that probably resulted in the death of a patient from an erroneous interpretation of POC-BG readings due to interference from high-dose vitamin C.

Methods: Retrospective case review. Read More

Perioperative hypoglycemia has been associated with adverse outcomes. Consequently, perioperative monitoring of blood glucose using convenient point-of-care (POC) monitors is frequently used. Although venous or arterial glucose POC testing has been cleared for use in critically ill hospitalized patients, the results of capillary glucose POC testing should be interpreted with caution because capillary POC samples are usually less reliable than those obtained from arterial or venous sites.

Herein, we present a case of pseudohypoglycemia induced by hypothermia in an 83-year-old white man in whom glucose levels between venous and capillary blood were discrepant. Although pseudohypoglycemia has been reported in the literature, it is under-recognized among health care professionals and laboratorians. Health care professionals may encounter pseudohypoglycemia using glucose meters; the potentially inaccuracy of glucose meter results for critically ill patients has been intensely debated recently.

Objective: To identify patients with an inaccurate diagnosis of hypoglycemia and discuss predisposing factors.

Methods: We describe our patient's clinical presentation, laboratory work-up, hospital course, and follow-up and review similar cases from the literature.

Results: A 27-year-old woman with Raynaud phenomenon was admitted because of symptomatic hypoglycemia. Read More

Two patients with complaints of hypoglycemia came for evaluation, and both complained of intermittent episodes of mental dullness, disorientation, confusion, and palpitations relieved by eating. Plasma glucose levels at the time of symptoms were always above 70 mg/dL. Initial onset of symptoms was within 1 to 2 years after cessation of repeated incest, and on recognition of this, both patients associated the onset of episodes of similar feelings with the acts of incest.

Four cases of coma, clinically typed as hypoglycaemic but without low blood sugar levels are presented. The clinical picture was rapidly normalised by immediate infusion with hypertonic glucosate. A tentative pathogenetic hypothesis is proposed and the Yager and Young "non-hypoglycaemia" syndrome is once more discussed. Read More
