Lurasidone-induced hyperosmolar hyperglycemic syndrome: A case report.

INTRODUCTION: Lurasidone has few metabolic adverse effects and is recommended as an alternative when other antipsychotic drugs considerably increase body weight or blood sugar concentrations. CASE PRESENTATION: An 81-year-old man with bipolar disorder developed hyperosmolar hyperglycemic syndrome as a side effect of lurasidone. Routine monitoring of blood glucose concentrations led to the early detection and treatment of this disease, preventing life-threatening complications. DISCUSSION AND CONCLUSION: We describe a rare case of lurasidone-induced hyperosmolar hyperglycemic syndrome. The mortality rate of this syndrome is estimated to be up to 20%. This rate is significantly higher than that of diabetic ketoacidosis (currently <2%). Although lurasidone is considered to have a low risk of raising blood glucose concentrations, symptoms of hyperglycemia must be evaluated and blood glucose concentrations should be monitored regularly.

Combined diabetic ketoacidosis and hyperosmolar hyperglycemic state in type 1 diabetes mellitus induced by immune checkpoint inhibitors: Underrecognized and underreported emergency in ICIs-DM.

Background: Combined diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic state (HHS) secondary to immune checkpoint inhibitors (ICIs) is extremely rarely reported among ICIs- diabetes mellitus (DM) cases and is always ignored by physicians. This study aimed to conduct a systematic review to recognize better the rare adverse event of combined DKA-HHS associated with immune checkpoints. Methods: A electronic search in Pubmed/Cochrane/Web of Science, complemented by manual searches in article references, was conducted to identify clinical features of ICIs-combined DKA-HHS. Results: we identified 106 patients with ICIs- type 1 diabetes mellitus (T1DM) from 82 publications: 9 patients presented a coexistence of metabolic acidosis, severe hyperglycemia, and/or DKA; All patients were not diagnosed as combined DKA-HHS. Compared with ICIs-DKA patients, combined DKA-HHS cases were prone to higher hyperglycemia (1020 ± 102.5 vs 686.7 ± 252.6mg/dL). Moreover, acute kidney injury (87.5% vs 28.6%) and prior chemotherapy (66.7% vs 31.6%) showed higher occurrences with the onset of ICIs-HHS or combined DKA-HHS.B. Conclusions: Combined DKA-HHS portends a poor diagnosis in patients with coexistence features of DKA and HHS, which healthcare professionals and patients should be aware of due to differences in treatment. Our observational retrospective case series shows that patients with more risk factors were more likely to develop combined DKA-HHS. We are the first to report this group of patients' clinical characteristics and outcomes.

Capecitabine-induced hyperosmolar hyperglycaemic state.

An elderly woman with metastatic breast cancer was admitted with hyperglycaemic hyperosmolar state (HHS) and an elevated haemoglobin A1C. For 1 week, she had experienced confusion, nausea and frequent urination. Preceding this, she had completed seven cycles of capecitabine chemotherapy for her breast cancer. She did not have a history of diabetes prior to chemotherapy. Given the temporal dysglycaemia following the patient's chemotherapy regimen, capecitabine was thought to be a probable offending agent. The patient was acutely treated for HHS, and was discharged on a basal-bolus insulin regimen. Her capecitabine was held pending review with her oncology team. The patient was ultimately titrated down to basal insulin only by her family doctor. Given the common use of capecitabine, it is important to recognise the risk of hyperglycaemic and hyperglycaemic emergencies as potential adverse effects. This highlights the need to monitor blood glucose throughout treatment to prevent hyperglycaemic emergencies.

Acute hyperosmolar hyperglycaemic state in cystic fibrosis-related diabetes caused by glucocorticoid and itraconazole interaction.

Hyperosmolar hyperglycaemic state (HHS) has not previously been reported in cystic fibrosis-related diabetes (CFRD). We report the case of a 15-year old boy with stable CFRD who developed acute HHS after treatment with glucocorticoids and itraconazole for presumed allergic broncho-pulmonary aspergillosis (ABPA). This case highlights the dangerous and preventable combination of high glucose intake, glucocorticoids and itraconazole inhibition of CYP3A4 (with resultant glucocorticoid accumulation) that can result in a state of life- threatening HHS in an adolescent with previously stable CFRD.

Diazoxide toxicity in a child with persistent hyperinsulinemic hypoglycemia of infancy: mixed hyperglycemic hyperosmolar coma and ketoacidosis.

BACKGROUND: Persistent hyperinsulinemic hypoglycemia of infancy (PHHI), also known as congenital hyperinsulinism, has been known to go into spontaneous remission, with patients developing diabetes in later life. A temporary phase of hyperglycemia is, however, rarely reported. CASE PRESENTATION: We describe a 16-month-old child, a known case of diazoxide responsive PHHI, presenting with mixed hyperglycemic hyperosmolar coma and ketoacidosis with rhabdomyolysis while on diazoxide treatment. The patient required temporary cessation of diazoxide and initiation of insulin infusion, followed by a relapse of hypoglycemia again necessitating diazoxide therapy. CONCLUSIONS: Hyperosmolar coma with ketoacidosis is a rare side-effect of diazoxide therapy, documented even in patients with persistent hyperinsulinemic hypoglycemia of infancy.

The Impact of Hyperosmolarity on Long-Term Outcome in Patients Presenting with Severe Hyperglycemic Crisis: A Population Based Study.

AIMS: We compared characteristics of patients with hyperglycemic hyperosmolar state (HHS) and patients with severe hyperglycemia without the signs of hyperosmolarity and ketoacidosis; analyzed long-term all-cause mortality and potential prognostic factors. METHODS: The studied population included 261 749 adults. HHS was diagnosed in patients with plasma glucose >33.0 mmol/L, ketonuria <1+, and serum osmolarity >320 mmol/L. Patients with plasma glucose >33.0 mmol/L, ketonuria <1+ and serum osmolarity <320 mmol/L were considered as controls (nHHS). RESULTS: During the 5-year period, we observed 68 episodes of HHS in 66 patients and 51 patients with nHHS. Patients with HHS were significantly older, had lower BMI, higher serum C-reactive protein and used diuretics and benzodiazepines more frequently. Mortality rates one, three and 12 months after admission were 19.0, 32.1 and 35.7% in the HHS group, and 4.8, 6.3 and 9.4% in the nHHS group (P<0.001). However, after adjustment for patient age, these differences were not statistically significant. In multivariate Cox regression in HHS group, mortality was positively associated with age, male gender, leukocyte count, amylase, presence of dyspnea and altered mental status, and the use of benzodiazepines, ACE inhibitors and sulphonylureas, while it was inversely associated with plasma glucose, bicarbonate, and the use of thiazides and statins. A nomogram derived from these variables had an accuracy of 89% in predicting lethal outcome. CONCLUSIONS: Infection, use of furosemide and benzodiazepines may be important precipitating factors of HHS. Prospective clinical trials are mandatory to analyze the safety of ACE-inhibitors and benzodiazepines in elderly patients with diabetes.

Hyperglycemic Hyperosmolar State During Induction Chemotherapy for Acute Lymphoblastic Leukemia.

We present the case of a 16-year-old boy who presented with fatigue, polyuria, and polydipsia while on chemotherapy for his relapsed acute lymphoblastic leukemia (ALL). Blood gas examination confirmed the diagnosis of hyperosmolar hyperglycemic state. The etiology for his hyperglycemia was most likely a result of oral glucocorticoid therapy combined with asparaginase therapy-both are a cornerstone of induction chemotherapy for ALL. The patient was aggressively rehydrated with saline, and medications were administered to correct his hyperkalemia. He was then slowly brought to euglycemia with a continuous infusion of insulin. Although hyperosmolar hyperglycemic state is rare during the treatment of ALL, frontline providers should be aware of this diagnosis because of the significant risk of hypovolemic shock and death if correction of hyperglycemia occurs prior to complete fluid resuscitation.

Reversible splenial lesion syndrome with a hyperosmolar hyperglycemic state and neuroleptic malignant syndrome caused by olanzapine.

A 27-year-old woman with panic disorder taking 20 mg olanzapine daily for 4 months was admitted to Mito Kyodo General Hospital, Mito, Ibaraki, Japan, because of disturbed consciousness with fever, hyperglycemia, hyperosmolarity and elevated creatine phosphokinase. She was diagnosed with a hyperosmolar hyperglycemic state and neuroleptic malignant syndrome. Brain magnetic resonance imaging showed transiently restricted diffusion in the splenium of the corpus callosum, with a high signal intensity on diffusion-weighted imaging. The neurological abnormalities disappeared along with improvement of metabolic derangements, and the follow-up magnetic resonance imaging carried out on the 26th day of admission showed complete resolution of the lesions in the splenium of the corpus callosum. These clinical and radiological features are highly suggestive of clinically mild encephalitis/encephalopathy with a reversible splenial lesion. The first case of mild encephalitis/encephalopathy with a reversible splenial lesion caused by olanzapine-induced hyperosmolar hyperglycemic state and neuroleptic malignant syndrome is reported.

Antipsychotic Therapy-Induced New Onset Diabetic Ketoacidosis.

Atypical antipsychotics are very widely used for various psychiatric ailments because of their less extrapyramidal side effects. Various reports of disturbances in glucose metabolism in the form of new onset diabetes mellitus, exacerbation of preexisting diabetes mellitus, diabetic ketoacidosis, hyperosmolar nonketotic coma, acute pancreatitis, and increased adiposity have been reported. We present a case of new onset diabetic ketoacidosis in a patient without a history of glucose intolerance who was being treated with olanzapine for bipolar disorder. He presented in hyperglycemic, hyperosmolar, hyperketotic state with hyperkalemia, and peaked T waves on electrocardiogram. He was treated with vigorous intravenous hydration, insulin, and kaexylate which stabilized his metabolic profile. He was discontinued off of his olanzapine and started on resperidol for his bipolar disorder. Over the course of 6 months, the patient was discontinued off of his insulin and has been doing well on his follow-up appointments. This case highlights the necessity of close blood glucose monitoring of patient on atypical antipsychotic medications irrespective of their diabetic status.

[In-hospital cardiac arrest due to unobserved steroid-induced hyperglycaemic hyperosmolar syndrome]. / Manglende diagnostik af hyperosmolært hyperglykæmisk syndrom førte til hjertestop.

The merging of hospital wards into highly specialized units facilitates targeted diagnostics and treatment. Often the result is favourable for the patient, but in some cases the basic conditions are overlooked. We describe a patient with inoperable oesophageal cancer who had unexplained mental confusion for three days due to an unobserved corticosteroid-induced hyperglycaemic hyperosmolar syndrome. The main differential diagnosis was cerebral metastases and a cerebral computed tomography was performed before cardiac arrest led to the right diagnosis. It is crucial to remember that unexplained deterioration in a patient with inoperable cancer can have a reversible cause.

Olanzapine-induced hyperglycaemic coma and neuroleptic malignant syndrome: case report and review of literature.

Although the relationship between antipsychotic medication, particularly second-generation antipsychotics (SGAs), and metabolic disturbance is increasingly accepted, there is an important, but little recognised, potential interaction between this and the other important serious adverse effect of neuroleptic malignant syndrome (NMS). We report a case of a 35-year old female who developed new onset type II diabetes mellitus with hyperosmolar hyperglycaemic coma and acute renal failure following treatment with a SGA for a first manic episode. The history is strongly suggestive of concurrent NMS. This case raises important questions about non-ketotic, hyperosmolar diabetic coma with antipsychotics, the possible association between hyperglycaemia and hyperthermia, and the direction of causality in this, the recognition of either syndrome when they co-exist and management issues in such patients. These questions are considered in the context of currently available literature.

Severe hyperglycemic hyperosmolar nonketotic coma in a nondiabetic patient receiving aripiprazole.

Aripiprazole is commonly used as an atypical antipsychotic. It has been associated with abnormalities in glucose metabolism. Severe diabetic complications associated with its use occur rarely. We present a case of a patient without a history of diabetes mellitus who presented to the emergency department in severe hyperosmolar nonketotic coma while using aripiprazole.

Descompensación hiperglucémica hiperosmolar en paciente trasplantado hepático en tratamiento con acetato de megestrol / Hyperosmolar hyperglycemic nonketotic syndrome in a liver transplant recipient treated with megestrol acetate

El acetato de megestrol es un progestágeno sintético con acciones e indicaciones similares a las de la progesterona y más recientemente ha sido utilizado para estimular el apetito en pacientes con caquexia asociada al cáncer y al síndrome de inmunodeficiencia humana adquirida (sida). Entre los efectos adversos descritos en relación con este fármaco están las anomalías del metabolismo hidrocarbonado. Presentamos el caso de un paciente que desarrolló un síndrome de descompensación hiperglucémica hiperosmolar no cetósica tras la introducción de acetato de megestrol como estimulante del apetito (AU)

Megestrol acetate is a synthetic, orally active progestational agent with actions and indications similar to those of progesterone. This agent has been used as an appetite stimulant in patients with cachexia associated with cancer and acquired immunodeficiency syndrome (AIDS). One of the adverse effects that has been described in relation with this drug is abnormal glucose metabolism. We present a case of hyperglycemic hyperosmolar nonketotic syndrome in a patient who received this agent as an appetite stimulant (AU)

Cisplatin-induced hyperglycemic hyperosmolar coma.

We present a case of severe hyperglycaemic hyperosmolar derangement after treatment with cisplatin in a patient without previous diabetes mellitus. Limited data are available on this adverse reaction, explaining why impaired glucose handling due to cisplatin is not generally recognised.
