Hypoglycemia secondary to factitious hyperinsulinism in a foster care adolescent - a case report of munchausen syndrome in a community hospital emergency department setting

Diffuse, Adult-Onset Nesidioblastosis/Non-Insulinoma Pancreatogenous Hypoglycemia Syndrome (NIPHS): Review of the Literature of a Rare Cause of Hyperinsulinemic Hypoglycemia

Differential diagnosis of hypoglycemia in the non-diabetic adult patient is complex and comprises various diseases, including endogenous hyperinsulinism caused by functional β-cell disorders. The latter is also designated as nesidioblastosis or non-insulinoma pancreatogenous hypoglycemia syndrome (NIPHS). Clinically, this rare disease presents with unspecific adrenergic and neuroglycopenic symptoms and is, therefore, often overlooked. A combination of careful clinical assessment, oral glucose tolerance testing, 72 h fasting, sectional and functional imaging, and invasive insulin measurements can lead to the correct diagnosis. Due to a lack of a pathophysiological understanding of the condition, conservative treatment options are limited and mostly ineffective. Therefore, nearly all patients currently undergo surgical resection of parts or the entire pancreas. Consequently, apart from faster diagnosis, more elaborate and less invasive treatment options are needed to relieve the patients from the dangerous and devastating symptoms. Based on a case of a 23-year-old man presenting with this disease in our department, we performed an extensive review of the medical literature dealing with this condition and herein presented a comprehensive discussion of this interesting disease, including all aspects from epidemiology to therapy.

Prevalence and characteristics of factitious hypoglycaemia in non-diabetic patients in a department of endocrinology

INTRODUCTION

Factitious hypoglycaemia is defined as the surreptitious use of insulin or oral hypoglycaemic agents to deliberately induce self-harm. It represents a challenging diagnosis and misdiagnosis is associated with significant morbidity and mortality. The aim of this study was to assess the prevalence and the associated factors of factitious hypoglycaemia in non-diabetic patients.

METHODS

This was a single-centre, retrospective study including 70 non-diabetic patients who were admitted for the investigation of hypoglycaemia. All patients fulfilled the Whipple triad. Epidemiological parameters, medical history, clinical and paraclinical data and the aetiology of hypoglycaemia were collected from medical records.

RESULTS

The diagnosis of factitious hypoglycaemia was held in 11 patients (9 women and 2 men) corresponding to a prevalence of 16%. It was secondary to intentional insulin use in six patients and the ingestion of glibenclamide in five patients. The median age of the patients was 28 years (interquartile range: 21-43). Two patients with factitious hypoglycaemia had a personal history of psychiatric disorders. The other causes of hypoglycaemia were adrenal insufficiency (34%), prediabetes (24%), insulinoma (6%), iatrogenic hypoglycaemia (10%), criminal hypoglycaemia (1%) and alcohol intoxication (2%). Age ≤ 35 years (Odds Ratio = 5.6, p = .017), family history of diabetes mellitus (Odds Ratio = 1.29, p = .015), attention disorders during hypoglycaemia (Odds Ratio = 12.5, p = .017) and fasting glucose level <0.7 g/L (Odds Ratio = 5.75, p = .017) were positively associated with factitious hypoglycaemia.

CONCLUSION

Factors significantly associated with factitious hypoglycaemia were young age, family history of diabetes and a low fasting glucose level.

Clinical Case of Surreptitious Hypoglycemia Due to Deliberate Insulin Analog Administration

Hypoglycemic syndrome is a life-threatening condition that can lead to hypoglycemic coma and death. Surreptitious hypoglycemic syndrome is the deliberate use of insulin preparations or oral hypoglycemic drugs aimed to reduce blood glucose level. If human insulin is injected, high level of immunoreactive insulin (IRI) and low level of C-peptide at the moment of hypoglycemia are always detected. However, the fact of deliberate administration of insulin analogs is difficult to prove. In these cases if insulin kit test with low cross-reactivity with insulin analogs is used, the low levels of IRI and C-peptide will be suspected. Some experts suggest the presence of cross reactivity with analogs of insulin in a number of commercial kits, which makes it possible to detect cases of surreptitious hypoglycemia. We present a clinical case of a patient with surreptitious hypoglycemia due to the administration of insulin analogs and discuss the problems of its laboratory diagnosis.

Insulin as a Tool in Factitious Dysglycemia

Factitious dysglycemia is a type of self-inflicted harm that includes deliberate attempts to induce hypo- or hyperglycemia as a sickness to gain empathy. We report the cases of three Iraqi women with different motives to induce factitious dysglycemia. Two of them had used insulin to induce hypoglycemia to have their family affection centered on them again. The third woman with type 1 diabetes mellitus intentionally missed her insulin doses to induce diabetic ketoacidosis and gain familial empathy through recurrent hospital admission, with underlying suicidal ideation. The problems with all women were discovered by a thorough history, physical examination, and with family help. They were referred to have psychiatric management. This is the first case series regarding factitious dysglycemia from Iraq.

Research Participation of Minor Adolescents in Foster Care

STUDY OBJECTIVE

In this study we evaluated published studies about foster care to: (1) determine the types of data used; (2) describe the degree to which a sexual/reproductive health topic was addressed; and (3) describe the consent process.

DESIGN

Analysis of published literature.

SETTING

PubMed was searched using "foster care" for English articles published between January 1, 2017 and September 4, 2019.

PARTICIPANTS

None.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

Articles were coded into 4 data source categories: primary, secondary, peripheral, or perspective data. Articles with a primary data source were coded for participant ages: only 9 years old and younger, 10- to 17-year-olds (minor adolescents), and only 18 years old and older. Articles using a secondary data source were coded for the source of the data registry. All articles were coded for presence of a sexual/reproductive health outcome. The primary data articles that included minor adolescents were coded for the study topic and consent process.

RESULTS

Of the 176 articles about foster care, 72/176 (41%) used primary data, 53/176 (30%) used secondary data, and 51/176 (29%) used peripheral/perspective data. Forty-eight of the primary data articles included minor adolescents. Secondary data sources included few national research surveys. Sexual/reproductive health outcomes were measured in 17 articles, 4 of which used primary data. The consent process for minor adolescents varied and had no consistent pattern across studies.

CONCLUSION

Research on best practices for consent processes and use of registries could be developed to increase research on sexual/reproductive health outcomes among adolescents in foster care.

Munchausen Syndrome by Tissue Plasminogen Activator: Patients Seeking Thrombolytic Administration

Purpose of Review

Munchausen syndrome by tissue plasminogen activator (tPA) is a phenomenon we describe as patients exhibiting factitious symptoms to assume the role of the sick patient, desiring and received tPA, with no alternative diagnosis or secondary gain to better account for their presentation. To illustrate this phenomenon and its magnitude, we present a series of cases of Munchausen syndrome by tPA, prevalence in our stroke center, and highlight one illustrative case.

Recent Findings

Of 335 cases with tPA administration over 29 months, 10 were confirmed as Munchausen syndrome by tPA, reflecting a 3.0% prevalence in our stroke center.

Summary

Munchausen syndrome by tPA is an underappreciated phenomenon encountered in evaluating patients with acute stroke symptoms. Administering tPA in Munchausen syndrome poses an ethical dilemma because standard of care favors rapid tPA administration, but administration can cause harm, burdens the healthcare system, and does not treat the patient's Munchausen syndrome.
