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.
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).
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.
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.
Patients with type 2 diabetes mellitus have impaired ketogenesis due to high serum insulin and low growth hormone levels. Evidence exists that ketone bodies might improve kidney and cardiac function. ...In theory, improved ketogenesis in diabetics may have positive effects. We aimed to assess the impact of diabetic ketosis on all-cause mortality in patients with type 2 diabetes mellitus presenting with hyperglycemic crisis. We analyzed 486 patients with diabetic ketosis and 486 age and sex-matched patients with non-ketotic hyperglycemia presenting to the emergency department. Cox proportional hazard models were used to analyze the link between patient characteristics and mortality. During an observation time of 33.4 months, death of any cause occurred in 40.9 % of the non-ketotic hyperglycemia group and 30.2 % of the DK group (hazard ratio in the diabetic ketosis group, 0.63; 95 % confidence interval 0.48–0.82;
P
= 0.0005). Patients with diabetic ketosis had a lower incidence of symptomatic heart failure and had improved renal function. They used less furosemide and antihypertensive drugs, more metformin and lower insulin doses, all of which was independently associated with decreased mortality. Plasma glucose and glycated hemoglobin levels were similar in both groups. Patients with hyperglycemic crisis and diabetic ketosis have decreased all-cause mortality when compared to those with non-ketotic hyperglycemia. diabetic ketosis might be a compensatory mechanism rather than a complication in patients with hyperglycemic crises, but further prospective studies are warranted.
- A rare case of necrotizing hypophysitis (NH) in a 52-year-old man presenting with pituitary apoplexy and sterile meningitis is described. This case indicates that the diagnosis of NH could be made ...without biopsy, based on concomitant presence of diabetes insipidus, hypopituitarism and radiologic features of ischemic pituitary apoplexy. Conservative management of pituitary apoplexy should be advised in NH. Additionally, this is the first report of a case of sterile meningitis caused by ischemic pituitary apoplexy.

Pituitary apoplexy may occur when a large tumor compresses or outgrows its nutrient supply, resulting in ischemic necrosis and hemorrhage. Although once deemed a neurosurgical emergency, increasing ...evidence suggests that conservative management of pituitary apoplexy leads to favorable neuro-ophthalmologic and endocrinologic outcomes as well. Spontaneous remission after pituitary apoplexy has been described in functioning pituitary adenomas, but it is a rare occurrence in nonfunctioning tumors.
We report a man that presented with pituitary apoplexy of a nonfunctioning pituitary macroadenoma that was managed conservatively and treated hormonally for hypopituitarism during a 2-year follow-up period, with serial neuroimaging demonstrating significant tumor volume reduction with almost complete resolution resulting in partial empty sella. In addition, a short literature review was performed pertaining to the management of pituitary apoplexy with emphasis on a more conservative approach.
A subset of patients with pituitary apoplexy without altered consciousness and nonprogressive or mild ophthalmologic deficits may be managed conservatively; however, lifelong periodic assessment, preferably by a specialized multidisciplinary pituitary team, is essential until clinical outcomes become clear.
Autori prikazuju rijedak slučaj nekrotizirajućeg hipofizitisa u 52-godišnjeg muškarca koji se inicijalno prezentirao apopleksijom hipofize i sterilnim meningitisom. Ovaj slučaj ukazuje na mogućnost ...da je dijagnozu nekrotizirajućeg hipofizitisa moguće postaviti i bez biopsije ako postoji patognomonična trijada ovoga sindroma: dijabetes insipidus, hipopituitarizam i radiološki znakovi ishemijske apopleksije hipofize. Dodatno, ovo je prvi opisani slučaj sterilnog meningitisa uzrokovanog ishemijskom apopleksijom hipofize.
