Hyperglycaemia in patients with no history of diabetes presenting to Internal Medicine Departments

Mixed insulin can improve control of prednisolone-induced hyperglycaemia

BACKGROUND

Hyperglycaemia is a common side effect of prednisolone, although there are no widely accepted guidelines for the management of glucocorticoid-induced hyperglycaemia (GIH). Our institution uses mixed insulin in a pre-breakfast or pre-breakfast and pre-lunch regimen, with the rationale that this profile of insulin action matches the physiological effect of prednisolone on blood glucose levels (BGLs).

AIM

Evaluate the use of the mixed insulin (NovoMix30) in a pre-breakfast or pre-breakfast and pre-lunch regimen as management for GIH in a tertiary hospital setting.

METHOD

We retrospectively evaluated all inpatients coprescribed prednisolone ≥7.5 mg and NovoMix30 for at least 48 hours over a 19-month period. BGLs were evaluated with repeated-measures analysis within four time periods across the day, beginning from the day prior to NovoMix30 administration.

RESULTS

A total of 53 patients were identified. NovoMix30 significantly reduced BGLs in the morning (mean 12.7 ± 4.5 vs. 9.2 ± 3.9 mmol/L, P < 0.001), afternoon (mean 13.6 ± 3.8 vs. 11.9 ± 3.8 mmol/L, P = 0.001) and evening (12.1 ± 3.8 vs. 10.8 ± 3.8 mmol/L, P = 0.01). With uptitration of insulin over 3 days, 43% of all BGLs were within the target range, compared with 23% on day 0 (P < 0.001). The final median dose of NovoMix30 was 0.15 (0.10-0.22) units/kg bodyweight, or 0.40 (0.23-0.69) units/mg of prednisolone, which is lower than our hospital guideline recommends. One overnight hypoglycaemic event was observed.

CONCLUSION

Mixed insulin as a pre-breakfast or pre-breakfast and pre-lunch regimen can target the hyperglycaemic pattern induced by prednisolone and minimise overnight hypoglycaemia. However, higher doses of insulin than those used in our study are likely required for optimal BGL control.

The role of diabetes mellitus on the formation of severe odontogenic abscesses-a retrospective study

Objectives

To analyze the correlation of diabetes mellitus and hyperglycemia with severe odontogenic abscesses.

Materials and methods

Records of all patients in the Department of Oral and Maxillofacial Surgery of the Medical Center of the Johannes Gutenberg-University who underwent inpatient treatment for severe odontogenic abscesses between 2010 and 2016 were evaluated retrospectively regarding diabetes anamnesis, maximum and fasting blood sugar count, and duration until discharge. In order to compare the numbers to a general maxillofacial group, all patients who received inpatient treatment in 2013 for any diagnosis other than an abscess of the head and neck region were analyzed as well, and the numbers were correlated.

Results

In total, 977 abscess patients were found in the analyzed period. 7.0% of the patients had a known diagnosis of diabetes mellitus type II and 0.6% of type I. Correlation with the general group showed that abscesses were significantly more likely in diabetics as well as patients with abnormal maximum and fasting blood sugar counts. These patients also needed significantly longer inpatient treatment.

Conclusions

Diabetics and patients with abnormal glucose tolerance show significantly higher numbers of severe odontogenic abscesses and might therefore benefit from earlier escalation of antibiotic medication.

Clinical relevance

Severe odontogenic abscesses are one of the most frequent diagnoses in maxillofacial practice. Adjusting the therapeutic approach for diabetics or patients with abnormal blood sugar counts might help to prevent the development of abscesses.

Diabetes and hyperglycemia as risk factors for postoperative outcome in maxillofacial surgery

BACKGROUND

Aim of this study was to investigate the frequency of complications in maxillofacial surgery in-patients in correlation to diabetes mellitus or a pathologically altered glucose metabolism.

MATERIALS AND METHODS

All patients' electronic health records were analyzed retrospectively. Diabetes mellitus anamnesis, the treatment regime, blood glucose levels, and the duration of inpatient treatment were recorded. Glucose readings ≥200 mg/dL measured at any time and fasting glucose levels of ≥110 mg/dL were defined as hyperglycemic. Noted complications were infection, dehiscence, swelling, and necrosis.

RESULTS

8.7% out of 1374 patients had a known diabetes diagnosis. 13.0% had high fasting glucose and 11.4% aberrant maximum glucose readings. Complications did not occur more often in patients with a previously known diabetes but more often in patients with high maximum blood glucose levels. Of these patients, only 56.3% were known diabetics.

CONCLUSIONS

Diabetes mellitus does not necessarily lead to higher frequency of complications in surgical patients. Moreover, patients with well-controlled diabetes seem to have a similar outcome compared to nondiabetics. Hyperglycemia however has an important impact on treatment outcome.

Prevalence of undiagnosed hyperglycaemia in patients presenting to the Department of Emergency Medicine with no known history of diabetes

BACKGROUND

Diabetes is considered a major epidemic of the 21st century. Usually, diabetes begins asymptomatically and the diagnosis takes place an average of 8-12 years after the onset of dysglycaemia. Blood check for glucose is taken at different medical setting, whether at the fasting condition or randomly. Previous studies had shown that abnormal blood glucose predicts future diabetes. Hence, medical staff should consider taking reasonable actions in patients with abnormal blood glucose.

OBJECTIVE

To assess the prevalence of hyperglycaemia in patients presenting to the Department of Emergency Medicine (DEM) with no known history of diabetes, and to evaluate how often were they recommended following this up as an outpatient by the medical staff.

DESIGN

A cross-sectional study examined the medical records of adult patients referred to the DEM during 1 November 2011-31 January 2012.

PARTICIPANTS

Patients with random blood glucose ≥140 mg/dL and no known history of diabetes were included in the study. The discharge letter was examined for the presence of instructions to conduct further follow up.

KEY RESULTS

A total of 16 784 patients presented to the DEM. Of these, 402 patients (2.4%) without known diabetes were hyperglycaemic, 346 patients had blood glucose levels ≥140 mg/dL and 56 patients had blood glucose levels above 200 mg/dL. Only 35 of the 402 included patient files (8.7%) contained instructions for further investigation. There was no statistically significant difference between those who received a letter for further follow up compared with those who did not receive it with respect to age, sex or blood glucose levels.

CONCLUSION

Over 2% of patients who presented to the DEM were hyperglycaemic, without a prior diagnosis of diabetes. A small per cent was recommended to have outpatient follow-up. This represents a missed opportunity for earlier diagnosis of diabetes and emphasised the need for raising medical staff awareness concerning abnormal blood glucose and its implication.

Diabetes Mellitus and Its Association to the Occurrence of Medication-Related Osteonecrosis of the Jaw

To date there is no consensus on the role of diabetes in the development of medication-related osteonecrosis of the jaws (MR-ONJ). Therefore, this study aimed to investigate the prevalence of diabetes and pathological glucose metabolism in patients with MR-ONJ compared to the general population. All maxillofacial surgery inpatients in one year at our department were investigated regarding diagnosis, anamnesis, medication, and blood glucose readings. 1374 records were analyzed. 35 patients with MR-ONJ were identified. Diabetics accounted for 14.3%. No significant difference in the prevalence of known diabetes was found, except for pathological glucose metabolism in patients with MR-ONJ (p < 0.001). Diabetes does not necessarily promote the onset of MR-ONJ. Therefore, diabetes should not be considered as a standalone risk factor. On the contrary, hyperglycemia as a possible indicator for poorly managed or yet undetected diabetes is associated with MR-ONJ.
