Causes and Management Strategies for Unusual Hypoglycemia: a Case Series.

Background: Glucose levels are vital for indicating the body's sugar content, with imbalances leading to diseases like diabetes or hypoglycemia-related symptoms such as palpitations and fatigue.

Methods: This case series describes three cases of hypoglycemia identified in recent years, utilizing multiple glucose measurement methods and exploring strategies to eliminate interferences.

Results: Two cases of pseudo-hypoglycemia induced by PEGylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) and Evolocumab injections, and one case of true reactive hypoglycemia following a glucose tolerance test in a patient post-gastric bypass surgery.

Analysis of a lung cancer case with transient pseudo hypoglycemia after PEG-rhG-CSF treatment.

Pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) is an effective treatment for chemotherapy-induced neutropenia. However, it can also induce various adverse effects, including fever, bone pain, and other discomforts arising from the abnormal proliferation of blood cells. This study presents an analysis of a case involving a middle-aged patient with small cell lung cancer who exhibited transiently low blood glucose levels without experiencing any symptoms of hypoglycemia following PEG-rhG-CSF treatment.

Autoverification-based algorithms to detect preanalytical errors: Two examples.

The preanalytical phase of testing accounts for the majority of the errors. Software-based quality rules, such as autoverification, can assist in preanalytical error detection; therefore, preventing erroneous results from being reported. Two autoverification rules, turbidity/lipemia, and pseudohypoglycemia/pseudohyperkalemia alarms, are highlighted.

Pseudohyperglycemia Secondary to High-Dose Intravenous Vitamin C Managed as Diabetic Ketoacidosis: An Endocrinological Catastrophe.

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.

Perioperative Glucose Management: Point-of-Care Testing and Pseudohypoglycemia.

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.

Discrepant Glucose Results between Capillary and Venous Blood in an 83-Year-Old White Man.

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.

[Pseudo-hypoglycemia and hyperleukocytosis: a case report].

Mrs B., 39 years old, hospitalized in the department of respiratory medicine for lung cancer, has an undetectable and verified venous blood glucose concentration (measured in central laboratory) less than 0.1 mmol/L.

Pseudohypoglycemia: a cause for unreliable finger-stick glucose measurements.

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.

[Syndrome of clinical pseudohypoglycemia].

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.
