A rare cause of hypoglycemia in adults

The aim of the study was to describe a clinical case of noninsulinoma pancreatogenous hypoglycemia (NIPH).

Materials and methods. Patient R. 42 years old, woman, was admitted with complaints on spastic abdominal pain, heartburn, flatulence, bloating. The patient had a history of cramping pains in the upper abdomen, episodes of hypoglycemia up to once a day, periodically diarrhea with undigested food up to 3 times a day, and frequent weakness during last 9 years. In 2013, she was diagnosed with a neuroendocrine tumor of the pancreas, and therefore distal pancreatectomy was performed that year. According to histological and immuno-histochemical studies, foci of islet-cell hyperplasia (nesidioblastosis) were noted in the tail of the pancreas against the background of tissue fibrosis. Non-insulinoma pancreatogenous hypoglycemia of adults (NIPH) was diagnosed, enzyme replacement therapy and Octreotide-depo were prescribed. Relapses were noted twice. Two weeks before admission, the patient noted episodes of hypoglycemia. Upon admission, the patient had state of moderate severity, irregular stools up to 3–4 times a day. Antibacterial treatment was carried out, enzyme replacement therapy, octreotide was continued.

Results. On the 7th day of hospitalization, the patient was stabilized: the level of glycemia was 4.5–4.9 mmol / l, the frequency and consistency of stool normalized. No data for decompensation of the disease has been received. The patient was discharged in a satisfactory condition.

Conclusion. This clinical case demonstrates the influence of NIPH on the patient’s quality of life and the need for constant vigilance against the recurrence of hypoglycemic episodes, despite the treatment. This case can improve the awareness about this rare but important disease.
