Recurrent hypoglycemic coma and diabetic ketoacidosis caused by insulin antibody. A rare case of type 1 diabetes mellitus.
    Revista medica de Chile, 2022, Volume: 150, Issue:1

    Insulin antibodies (IAs) induced by exogenous insulin rarely cause hypoglycemia. However, insulin autoantibodies (IAAs) in insulin autoimmune syndrome (IAS) can cause hypoglycemia. The typical manifestations of IAS are fasting or postprandial hypoglycemia, elevated insulin level, decreased C-peptide levels, and positive IAA. We report a 45-year-old male with type 1 diabetes mellitus (T1DM) treated with insulin analogues suffering from recurrent hypoglycemic coma and diabetic ketoacidosis (DKA). His symptoms were caused by exogenous insulin and were similar to IAS. A possible reason was that exogenous insulin induced IA. IA titers were 61.95% (normal: < 5%), and the concentrations of insulin and C-peptide were > 300 mU/L and < 0.02 nmol/L when hypoglycemia occurred. Based on his clinical symptoms and other examinations, he was diagnosed with hyperinsulinemic hypoglycemia caused by IA. His symptoms improved after changing insulin regimens from insulin lispro plus insulin detemir to recombinant human insulin (Gensulin R) and starting prednisone.

Successful treatment of severe refractory sulfonylurea-induced hypoglycemia with octreotide.
    Diabetes care, 1993, Volume: 16, Issue:1

    To test the clinical use of octreotide in the treatment of sulfonylurea-induced hypoglycemia.. A case is reported of sulfonylurea-induced hypoglycemic coma in a nondiabetic subject, which was complicated by relapse of hypoglycemia after resuscitation with intravenous dextrose. Subcutaneous octreotide, 50 micrograms 12 hourly, suppressed stimulated endogenous insulin secretion, thereby preventing a further recurrence of hypoglycemia.. No adverse effects of treatment were observed.. These results suggest a significant role for octreotide as an adjunct to intravenous dextrose in the management of severe and refractory cases of sulfonylurea-induced hypoglycemia.

Specificity of hypoglycaemia for cerebral malaria in children.
    Lancet (London, England), 1990, Aug-25, Volume: 336, Issue:8713

    Glycaemic status on hospital admission was compared in 97 children with severe falciparum malaria (36 with cerebral malaria) and 89 children with other serious illnesses (32 in coma; 57 with acute pneumonia, not in coma). The frequency of hypoglycaemia (blood glucose below 2.2 mmol/l) did not differ significantly between malarial and control patients (5.2% vs 11.2%) nor between the comatose (11.1% vs 18.8%) and conscious (1.6% vs 7.0%) malarial and control subgroups. Compared with normoglycaemic patients, hypoglycaemic patients had appropriately low serum insulin (3.0 vs 8.2 mU/l) and C-peptide (0.13 vs 0.42 mmol/l) and high plasma non-esterified fatty acids (1.42 vs 0.83 mmol/l). Hypoglycaemia, the level of consciousness, and death were all significantly associated with the time since the last meal. Hypoglycaemia is not a specific complication of malaria but is found in severely ill fasted children, resulting from glycogen depletion and perhaps impaired hepatic gluconeogenesis. It should be sought in all severely sick children. A single bolus dose of glucose may not be enough to correct it.
