Frequency of Insulin Omission and It’s Associated Factors in Patients with Type 2 Diabetes Mellitus on Insulin Therapy

ABSTRACT Background: Poor adherence to prescribed insulin regimen leads to poor glycemic control. This study was intended to see the frequency of insulin omission and it's associated factors among patients with inadequate glycemic control on insulin therapy. Methods: This cross-sectional observational study enrolled 384 patients with type 2 diabetes on insulin therapy recruited by convenient sampling from the Department of Endocrinology of BIRDEM General Hospital. As per study protocol, investigation reports were collected from patient records. Data were analyzed by SPSS version 25. Results: Forty-six percent of patients had some form of insulin omission. A documented event of one or more episodes of hypoglycemia (70.7%) was found to be the prime reason behind the omission of insulin. Worsened glycemic control (fasting plasma glucose, 2-h postprandial glucose, and glycated hemoglobin) and health hazard (obesity) were statistically significantly higher among the subjects who omitted their insulin. Only a few people in the insulin omission group were compliant with diet (2.8%), exercise (5.1%), and weekly self-monitoring of blood glucose (2.8%). Only 22.5% and 21.3% knew about target blood glucose and the insulin dose adjustment, respectively, in the omission group. Conclusions: High frequency of insulin omission due to several lifestyle-related factors and lack of structured diabetic education predisposed the patients to poor glycemic control.

Reducing insulin omission errors among patients with diabetes mellitus in general surgical wards: a best practice implementation project.

Omission of insulin, a high-alert medication with one of the highest locally reported errors, could lead to severe hyperglycemia, which could result in coma or death if not treated timeously. This study aimed to identify, evaluate, and implement strategies to reduce the occurrence of insulin omission errors in diabetic adult patients requiring insulin. This project followed the JBI Evidence Implementation Framework and conducted context analysis, strategy implementation, and evaluation of outcomes according to evidence-based quality indicators. The JBI PACES and JBI GRiP situational analysis tools were used to support data collection and implementation planning. There was one evidence-based criterion and five sub-criteria, with a sample size of 22 patients. There was increased compliance with best practices to reduce interruptions and distractions from baseline audit (50%) to follow-up audits 1 (45.4%) and 2 (31.8%), and no insulin omission incidences during the implementation period. In the post-implementation analysis, there were notable improvements in compliance with strategies related to nurses; however, reduced compliance was observed related to patients. Key barriers to implementation included patients still disturbing nurses despite the nurses wearing the medication vests and patients forgetting instructions not to disturb nurses during medication administration. Strategies to improve compliance included ensuring coverage in each cubicle during insulin preparation and administration, tending to patients' needs prior to insulin administration, and use of posters as reminders. There was an overall increase in compliance with best practice to reduce interruptions and distractions and no insulin omission incidences related to interruptions and distractions during the implementation phase. http://links.lww.com/IJEBH/A219.

Association Between Type 1 Diabetes Mellitus and Eating Disorders: A Systematic Review and Meta-Analysis.

Previous meta-analyses have shown mixed results regarding the association between eating disorders (EDs) and type 1 diabetes mellitus (T1DM). Our paper aimed to analyse different EDs and disordered eating behaviours that may be practiced by patients with T1DM. A literature search of PubMed, Scopus and Web of Science was conducted on 17 January 2023, using the key terms "T1DM," "Eating Disorders" and "Bulimia." Only observational controlled studies were included. The Revman software (version 5.4) was used for the analysis. T1DM was associated with increased risk of ED compared with nondiabetic individuals (RR = 2.47, 95% CI = 1.84-3.32, p-value < 0.00001), especially bulimia nervosa (RR = 2.80, 95% CI = 1.18-6.65, p-value = 0.02) and binge eating (RR = 1.53, 95% CI = 1.18-1.98, p-value = 0.001). Our analysis has shown that increased risk of ED among T1DM persisted regardless of the questionnaire used to diagnose ED; DM-validated questionnaires (RR = 2.80, 95% CI = 1.91-4.12, p-value < 0.00001) and generic questionnaires (RR = 2.03, 95% CI = 1.27-3.23, p-value = 0.003). Prevalence of insulin omission/misuse was 10.3%; diabetic females demonstrated a significantly higher risk of insulin omission and insulin misuse than diabetic males. Our study establishes a significant and clear connection between EDs and T1DM, particularly bulimia and binge eating, with T1DM. Moreover, female diabetics are at higher risk of insulin misuse/omission. Early proactive screening is essential and tailored; comprehensive interventions combining diabetes and ED components are recommended for this population, with referral to a specialised psychiatrist.

Association Between Eating Disorders and Type 1 Diabetes Mellitus: a Systematic Review and Meta-Analysis

Introduction Type 1 diabetes mellitus (T1DM) patients are treated via insulin which could result in weight gain. Studies have coined a new term, “Diabulimia” which refers to the limitation or skipping of insulin doses, with the objective of weight control. A previous meta-analysis has found that eating disorders (ED) are significantly associated with T1DM (Mannucci, E et al. J Endocrinol Invest 2005; 417-9), while a more recent one, has shown an insignificant association between ED and T1DM on analysis of diabetes-adapted questionnaires only (Young V, et al. Diabet Med. 2013:189-198)ObjectivesWe aimed to re-analyze the association between ED and T1DM, whilst taking into account recently published literature and the type of questionnaire utilized.MethodsA literature search of PubMed, Scopus, and Web of Science was conducted on 17th January 2023, using the key terms “ T1DM”, “Eating Disorders”, and “ Bulimia”. Only Observational controlled studies were included.Results T1DM was associated with increased risk of ED compared to non-diabetic individuals (RR = 2.47, 95% CI = 1.84 to 3.32, p-value &lt; 0.00001), especially bulimia nervosa (RR = 2.80, 95% CI = 1.18 to 6.65, p-value = 0.02) and binge eating (RR = 1.53, 95% CI = 1.18 to 1.98, p-value = 0.001), while no significant association was seen between T1DM and anorexia nervosa. Our sensitivity analysis has shown that increased risk of ED among T1DM persisted regardless of the questionnaire used to diagnose ED; DM-validated questionnaires (RR = 2.80, 95% CI = 1.91 to 4.12, p-value &lt;0.00001) and generic questionnaires (RR = 2.03, 95% CI = 1.27 to 3.23, p-value = 0.003). Furthermore, the Eating Attitudes Test-26 (EAT) showed a significant increase in the dieting subscale (MD = 2.95, 95% CI = 1.84 to 4.06, p-value &lt; 0.00001) and bulimia subscale (MD = 0.78, 95% CI = 0.12 to 1.44, p-value = 0.02) among T1DM patients. Additionally, the Bulimic Investigatory Test, Edinburg (BITE) showed a significant increase in the symptom subscale (MD = 0.31, 95% CI = 0.12 to 0.50, p-value = 0.001), however, no significant difference was detected between T1DM and controls in the severity subscale. Prevalence of insulin omission/misuse was 10.3% (95% CI = 8.1-13); diabetic females demonstrated significantly higher risk of insulin omission (RR = 14.21, 95% CI = 2.66 to 76.04, p-value = 0.002) and insulin misuse (RR = 6.51, 95% CI = 1.14 to 37.31, p-value = 0.04) compared with diabetic males. Analysis of other potentially unhealthy weight control behaviors showed insignificant associations between fasting, excessive exercise, dieting pills misuse, diuretics misuse, and T1DM.ConclusionsT1DM patients are at higher risk of developing ED according to both generic and diabetes-validated questionnaires. Moreover, female diabetics are at higher risk of insulin misuse/omission. Subsequently, patients should be regularly screened and early psychiatric management is warranted.Disclosure of InterestNone Declared

Renal failure following insulin purging in atypical anorexia nervosa and type 1 diabetes mellitus.

Anorexia nervosa (AN) and atypical anorexia nervosa (AAN) are severe and complex eating disorders that can be prevalent among individuals with type 1 diabetes mellitus (T1DM). Insulin purging, characterized by the intentional underuse / omission of insulin to control weight, is under-recognized in medicine and is a purging strategy of patients with AN or AAN and comorbid T1DM. Often, this can lead to renal failure, necessitating a (pancreas-) kidney transplantation. This article presents a comprehensive overview of the interplay between AN/AAN and T1DM and summarizes the evidence in literature. A narrative review is presented on basis of a detailed case study of a 32-year-old female with end-stage renal failure seeking (pancreas-) kidney transplantation displaying etiology, diagnosis, comorbidities, complications, and treatment of AN and AAN with emphasis on those patients with T1DM. Insulin purging in patients with AN/AAN and coexisting T1DM can exacerbate T1DM complications, including accelerating the onset of end-stage renal failure. A multidisciplinary approach including nutrition treatment and psychotherapeutic techniques was considered necessary for treatment, focusing on psychosomatic in-patient care before and after organ transplantation. Insulin purging in patients with AAN and T1DM poses severe health risks, including accelerated renal complications. For those considering transplantation, insulin purging has explicitly to be diagnosed and a holistic treatment addressing both the renal condition and psychosomatic symptoms/disorders is crucial for successful post-transplant outcomes.

To study risk factors and biochemical profile of diabetic ketoacidosis patients with special emphasis on serum amylase

Background: Diabetes mellitus (DM) is a complex endocrinological disorder with altered metabolism of blood glucose. Diabetic ketoacidosis (DKA) is one of the life-threatening acute complications of DM that mainly occurs in type 1 diabetes patients, as well as in some patients with type 2 diabetes. The mortality rate associated with DKA depends on the experience of the treating hospital in dealing with this condition; thus, it is critical that patients detect DKA and get medical help as soon as possible. Aims and Objectives: To study risk factors for DKA, clinical and biochemical profile of DKA patients. Correlation between serum amylase level, serum bicarbonate level and mean duration of hospital stay. Materials and Methods: A cross-sectional analytical study was carried out on 100 DKA patients in the Department of Medicine, SGMH Rewa, Madhya Pradesh from January 2021 to June 2022. The data extracted included clinical presentation, precipitating factors, laboratory profile, complications, and hospitalization outcomes. Results: Of the 100 patients admitted for DKA; 70 had type 2 diabetes (70%) and 30 (30%) were type I diabetes. The average age at the time of presentation was 48.61±19.59 years. The commonest precipitating factor was infection (38%) followed by other factors (62%). The most common clinical features at the time of presentation were altered sensorium, fever, vomiting, polyuria, polydipsia, weakness, lethargy, myalgia, headache, anorexia, abdominal pain, and orthopnea. The values for RBS, HCO3, and pH were 525.0±62.4, 12.6±2.69, and 7.14±0.31, respectively. There was no significant difference in clinical and biochemical profile of patients with type 1 and type 2 diabetes. The mortality rate was 3% and factors found to be significant predictors were comorbid condition, severity of mental status, severity of dehydration, RBS at the time of presentation, and severe acidosis. Conclusion: The most common precipitating factors are infection and omission of insulin or irregular treatment. The most common clinical features at the time of presentation are nausea, vomiting, abdominal pain, headache, and dehydration. There is no significant difference in the clinical and biochemical profile of patients with type 1 and type 2 diabetes. The mortality rate in DKA is 3% and the most notable predictors of poor prognosis are; severity of altered sensorium, severity of comorbid condition, severe dehydration, severe acidosis, and identification and treatment of precipitating factors are more important. Patient education plays a crucial role in the prevention of DKA.

Validation of the traditional Chinese version of the diabetes eating problem survey-revised and study of the prevalence of disordered eating patterns in Chinese patients with type 1 DM

BackgroundDisordered eating behaviours (DEBs) in patients with type 1 diabetes mellitus (T1DM) are associated with an increased risk of complications and mortality. The Diabetes Eating Problem Survey-Revised (DEPS-R) was developed to screen for DEBs in T1DM patients. The objectives of this study were to develop a traditional Chinese version DEPS-R (electronic version) and to measure the prevalence of DEBs in a local population sample.MethodsThe DEPS-R was translated into traditional Chinese, modified and developed into an electronic version. The psychometric properties of the C-DEPS-R were tested on T1DM patients from 15 to 64 years old. The factor structure of the traditional C-DEPS-R was examined by confirmatory factor analysis (CFA). The C-EDE-Q and the C-DES-20 were used for convergent and divergent validity testing, respectively. Module H of the CB-SCID-I/P was used as a diagnostic tool for eating disorders. A correlation study was conducted with the C-DEPS-R scores obtained and the clinical characteristics. Type 2 diabetic (T2DM) patients on insulin treatment were recruited as controls.ResultsIn total, 228 T1DM patients and 58 T2DM patients were recruited. There was good internal consistency of the traditional C-DEPS-R (electronic version), with the McDonald’s omega of 0.825 and test-retest reliability of 0.991. A three-factor model of the traditional C-DEPS-R was confirmed by CFA. The cut-off score for the traditional C-DEPS-R was determined to be 24; 13.2% (95% CI 8.8%-17.5%) of T1DM patients were found to score above the cut-off score, while 7.5% (95% CI 4-10.9%) scored above the cut-off by the C-EDE-Q, and 4.4% (95% CI 2.1%-7.9%) were diagnosed with eating disorders by the CB-SCID-I/P Module H. Females with T1DM scored higher on the traditional C-DEPS-R. There was a significant correlation of the C-DEPS-R with BMI, occurrence of DKA, use of a continuous glucose monitoring system and positive diagnosis by the CB-SCID-I/P module H (p < 0.05).ConclusionThe traditional Chinese-DEPS-R (electronic version) demonstrated good psychometric properties. It is a self-rated, time-efficient and reliable tool for the screening of disordered eating behaviours in T1DM patients in the Chinese population of Hong Kong.Plain English SummaryDisordered eating behaviours, such as insulin omission, are associated with an increased risk of diabetes mellitus-related complications and mortality. Generic screening tools for eating disorders may over- or underestimate such problems in diabetic patients. Type 1 diabetes mellitus patients are at particular risk of developing disordered eating behaviours or eating disorders, yet studies in Chinese populations are limited. This study developed and validated the traditional Chinese (electronic) version of the Diabetes Eating Problem Survey-Revised (DEPS-R). The traditional Chinese-DEPS-R is a self-rated, time-efficient and reliable tool for the screening of disordered eating behaviours in Type 1 diabetes mellitus patients in the Chinese population of Hong Kong. The study also estimated the prevalence of disordered eating behaviours in diabetic patients from the local Chinese population, and the clinical correlations of the symptoms and clinical parameters were explored. The study reflected a higher prevalence of eating problems in the Type 1 diabetes mellitus population and demonstrated significant correlations of eating problems with BMI as well as the occurrence of diabetic ketoacidosis.

An Audit of Factors Impacting the Time to Resolution of the Metabolic Parameters in Diabetic Ketoacidosis Patients.

Diabetic ketoacidosis (DKA) is a major complication affecting patients with diabetes. It is often the first presentation of type I diabetes and can also occur due to a lack of compliance with insulin therapy or infection, among other causes. Hospitalizations for DKA have increased globally among patients with type I and type II diabetes, which poses a strain on health systems. To determine the factors impacting the time to resolution of metabolic parameters in DKA patients. This retrospective study was performed by reviewing the clinical records of hospitalized DKA patients at King Fahad Specialist Hospital, a tertiary-level healthcare center in Buraidah, Al Qassim region, Saudi Arabia. The study included all DKA admissions that met the inclusion criteria between September 2019 and April 2022. A total of 129 patients with a diagnosis of DKA from January 2019 to April 2022 were identified. Of these, 67 patients met the inclusion criteria. More females experienced DKA (56.7%), and the study population had an improvement rate of 97%. The mean length of stay (LOS) for patients with DKA was 73.19 hours, and the median time for DKA resolution was 15 hours (mean time 21.38 hours). The omission of insulin was the leading precipitating factor for DKA (43%) followed by infection (12%). A high serum bicarbonate (HCO3) level was identified as an independent predictor for a longer time to resolution. Patients with DKA who have high glucose levels on admission, higher body mass index (BMI), older age, and higher weight stayed in the hospital for extended periods. Conversely, patients with a higher serum potential of Hydrogen (pH) had a shorter LOS. Age was the only clinically independent predictor for a minimum LOS for DKA. Patients with comorbidities had a longer hospital LOS than patients without comorbidities; no such relationship has been reported in other studies. Patients in our study population had a longer time of resolution than observed in other studies, although no clear cause was identified. This study contributes to our understanding of DKA in hospitalized patients in Saudi Arabia. This is the first study to link patients with DKA who have comorbidities to a longer hospitalstay in the kingdom of Saudi Arabia. This study also identified multiple clinical and biochemical parameters related to the variability in LOS and time to resolution of DKA in hospitalized patients.

DKA Prevention and Insulin Pumps: Lessons Learned From a Large Pediatric Pump Practice.

This purpose of the study was to describe recent diabetic ketoacidosis (DKA) incidence data in youth with type 1 diabetes using insulin pumps and the impact of continuous glucose monitors (CGMs) on DKA rates. DKA data were obtained through a retrospective chart review of insulin pump users (ages <26 years) between December 2019 and June 2021 in an academic pediatric endocrinology practice where 68% of patients were pump users. Among 591 pump patients, 28 events occurred (3.16 events per 100 patient-years). Mean age was 13.6±3.4 years; 85.7% ranged from 12 to 19 years. Mean A1C was 10.2±2.3%, diabetes duration was 6.1±4.0 years, and 57.1% used CGM. Admission pH levels ranged between 7.0 and 7.31, with 28.6% of events classified as "moderate" and 46.4% "severe." There was no significant difference in the DKA severity between those who wore a CGM and those who did not (ie, pH, serum bicarbonate, mentation alteration, length of stay, intensive care unit admission, and hospital admission). DKA events were attributed to concurrent illness (10.7%), insulin omission (14.3%), pump site failure (57.1%), or other pump malfunctions (14.3%). DKA events in pump-treated patients were relatively uncommon; most episodes occurred in adolescents with higher A1C levels, and notably, most events could have been avoided if users followed standard troubleshooting guidelines. Thus, DKA prevention education should be reinforced at each encounter, particularly for teens with higher A1C levels. Moreover, more than 50% of those with DKA episodes wore a CGM, suggesting that pump users using CGM require frequent reinforcement of this education and that the development of such educational materials is critical.

165-LB: The Impact of COVID-19 Vaccination on Development of Hyperglycemic Crisis

Hyperglycemic crisis (HC) has been reported in patients with COVID-19 infection, but there is little data about HC following COVID-19 vaccination, with 10 patients described to date. We performed a retrospective observational study examining the correlation between COVID-19 vaccination and HC in adult patients admitted from 1/1/21-7/1/21 at our institution. There were 91 admissions for HC during the study period. Forty-one were admissions for diabetic ketoacidosis (DKA) in patients with type 1 diabetes (T1D) , 2 of which also had hyperglycemic hyperosmolar state (HHS) . In patients with type 2 diabetes (T2D) , there were 49 admissions for DKA, 6 of which also had HHS, and 1 admission for HHS alone. In patients with T1D, 17 admissions occurred following COVID-19 vaccination, ranging from &amp;lt;24 hours to more than 3 months after, including 1 new diagnosis of T1D. All cases had a trigger of insulin omission or other medical illness, including 7 with admission for COVID-19 infection. In patients with T2D, 20 DKA or overlap admissions and 1 HHS admission occurred following COVID-19 vaccination, ranging from 1 to 40 days after. Six of these patients had no clear trigger of medical illness or insulin omission, 3 of which were new diagnoses of T2D. Two were following the first vaccination and 4 following the second vaccination. Hemoglobin A1c at admission was &amp;gt;11% in all 6 of these patients. Among patients with T1D, there were no cases of HC that appeared to be attributable to COVID-19 vaccination. In patients with T2D, while there were six cases following vaccination with no other clear trigger, the degree of hemoglobin A1C elevation at the time of admission was suggestive of longer duration of poor glycemic control. Three of these cases did have acute symptom onset following vaccination within one week of presentation, so it is possible that HC was provoked by vaccination in these patients. While it is not clear that COVID vaccination leads to HC in T1D, it may be an acute trigger for HC in patients with T2D who have poor underlying glycemic control. Large scale population studies are needed to better assess rates of HC following COVID-19 vaccination. Disclosure K. L. Modzelewski: None. S. Alexanian: None.

510-P: DKA Prevention on Insulin Pumps: Lessons Learned from a Large Pediatric Pump Practice

While the Type 1 Diabetes Exchange data noted that diabetic ketoacidosis (DKA) is more common in those utilizing injection regimens than insulin pumps, DKA remains a risk for pump users, as it can precipitously develop if insulin infusion is interrupted. We sought to obtain more recent DKA admission data in T1D youth using insulin pumps and the impact of CGM on DKA rates. Methods: We characterized DKA data in insulin pump users from episodes between 12/20 and 6/2021 in an academic pediatric endocrine practice in which 68% were pump users. Results: Among 591 pump patients aged &amp;lt;25 years (y) , 28 events occurred (3.16 events per 100 patient-y. Mean age was 13.6±3.4y; 85.7% were 12-19y old. More events were in males (60.7%) , 53.6% were white, 71.4% non-Hispanic. Mean HbA1c was 10.22.3%, diabetes duration 6.1±4.0y, and 57.1% used CGM; 28.6% of patients were new to pump therapy (&amp;lt;1y) .Admission pH levels ranged between 7.0-7.31, with 28.6% of events classified as “moderate” and 46.4% as “severe.” Average length of stay was 2.0±0.7 days. While there was no significant difference in pH levels, CGM wearers had higher admission bicarbonate values (11.8 vs. 9.3, p=0.04) . Clinicians assessed the cause of DKA to be related to concurrent illness (10.7%) , insulin omission (14.3%) , pump infusion site failure (57.1%) or other pump malfunctions (14.3%) . For most (60.7%) , this was the first documented DKA event. Alcohol consumption was a contributing factor in only one event. Conclusions: DKA events were relatively uncommon; most episodes occurred in adolescents in poor diabetes control. Notably, most events could have been avoided if users followed standard trouble shooting guidelines. Thus, education on DKA prevention should be reinforced at each visit, particularly for teens on pumps with higher A1c levels. Moreover, while CGM wearers had higher admission bicarbonate values, over 50% of those hospitalized for DKA wore a CGM, suggesting even pump users using CGM require frequent reinforcement of DKA prevention education.

Eosinophilia and hyperglycemia: a friend or foe?

Infectious disease can precipitate new onset diabetes, complicate diabetic ketoacidosis or derange hyperglycemia. There are well studied mechanisms like an increase in production of pro inflammatory cytokine (TNF A, IL-B, and IL-6) which causes spike in the blood glucose level. However, some observational and invitro studies have shown that eosinophil do have a role in glycemic stabilization through alternatively activated macrophages (AAM). A 40-year-old male, not a known diabetic, was referred to our hospital for evaluation of high eosinophil count and hyperglycemia. He found to have severe eosinophillia, serological test for filarial positive and responded to heterazan therapy. His repeated blood smear test for microfilaria was negative. He was initially started on insulin basal bolus regimen (10 units total per day) and attained quick glycemic control with omission of insulin and with single dose of metformin 500 mg. In vitro studies on animals have also shown that when mice were fed with a diet of helminth, they showed sustained metabolic response characterized by decreased fasting glucose, improved insulin sensitivity and glucose tolerance. We discuss the controversial concept of the association whether eosinophilia increases the risk profile or does it mitigate the risk of the deadly disease, diabetes.

Intensive sick day rules to prevent recurrent diabetic ketoacidosis- An intervention that exemplifies health disparities

ObjectiveDiabetic ketoacidosis (DKA) is the leading cause of morbidity and mortality in children with type 1 diabetes (T1D). In established T1D patients, DKA is frequently a result of insulin omission or inadequate insulin administration during illness or stress. Ethnic minorities and patients with lower socioeconomic status are affected disproportionately. We hypothesized that implementation of intensive sick day rules with frequent reinforcement would reduce hospitalizations secondary to DKA in T1D youth irrespective of their demographics. MethodsIntensive sick day rules were implemented beginning January 2016. All T1D patients seen in the pediatric endocrinology clinic or hospital between January 1st 2015 through December 31st 2017 were included for chart review. Categorical variables were analyzed with Chi-square test. For the continuous variables, t test was used. Episodes of DKA per 100 patients were compared using the trends test over the three-year period. Patients who had DKA in 2015 were analyzed as a subgroup. ResultsThe frequency of DKA episodes per 100 patient years for 2015 was 19.1, for 2016 was 15.2 and was 12.4 for 2017. This decrease was statistically significant (p=0.006). The decline was also statistically significant for the subgroup of patients who developed DKA in 2015 and followed longitudinally. The decline was not uniform across all patient groups and DKA episodes remained associated with African- American race, Medicaid insurance status and higher HbA1c throughout the years. ConclusionImplementation of intensive sick day rules led to a decrease in total number of DKA admissions in our population with T1D youth. However, this intervention did not reduce the health disparity in this population and African-Americans on Medicaid insurance continued to form the disproportionate majority of admissions with DKA. This study highlights the need for further research into interventions that can improve outcomes across racial and socio-economic barriers.

Vomiting and hyperkalemia are novel clues for emergency room diagnosis of type 1 diabetic ketoacidosis: a retrospective comparison between diabetes types.

Diabetic ketoacidosis (DKA) is an acute life-threatening complication in patients with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM). Causes, underlying pathophysiology, and mortality differ significantly by diabetes type, which initial treatment is dependent on, but few reports on these differences are available. This study aimed to clarify differences in clinical characteristics between the diabetes types to extract important clinical clues for preventing DKA and ensuring appropriate initial treatment in the emergency room. We retrospectively analyzed the clinical presentation of 24 T1DM patients and 13 T2DM patients admitted with DKA to Kobe City Medical Center West Hospital between April 2006 and December 2018. In T1DM, the main causes were insulin omission and new onset, and important factors were also misdiagnosis with consequent inappropriate insulin prescription and older age with dementia. In T2DM, the main causes were infection and excessive soft drink consumption. For all soft drink ketosis patients, this was the first presentation of diabetes. The main complaint differed between diabetes types. Vomiting was a characteristic symptom in T1DM DKA; most T2DM DKA patients presented with generalized malaise or decreased level of consciousness. On blood examination, serum potassium level was higher and HbA1c was lower in T1DM DKA. To prevent DKA, it is important to provide social support for elderly patients with T1DM DKA and lifestyle intervention for younger T2DM or obese patients. Vomiting and serum potassium levels contribute to the classification of diabetes type and subsequent initial treatment in the emergency room.

Clinical, psychological and demographic factors in a contemporary adult cohort with diabetic ketoacidosis and type 1 diabetes.

Diabetic ketoacidosis (DKA) is a potentially life-threatening but often preventable acute complication of type 1 diabetes (T1D). Understanding clinical and psychosocial characteristics of people with DKA, particularly those with multiple presentations, may aid the development of prevention strategies. To describe clinical, psychological and demographic factors in adults with DKA and particularly those factors associated with recurrent admissions. A retrospective analysis was performed of all admissions with DKA in people with T1D over a 4-year period from 1 November 2013 to 31 October 2017 at a metropolitan tertiary hospital in Australia. Potential cases were identified by International Classification of Diseases-10th Revision coding data. Data were then manually extracted by clinicians from the electronic medical record. There were 154 clinician-adjudicated admissions for DKA among 128 people with T1D. Of these, 16 (13%) had multiple DKA admissions. Forty-one (32%) had a history of depression. The most common factors contributing to presentation included insulin omission (54%), infection (31%), alcohol excess (26%) and new diabetes diagnosis (16%). Compared to people with single admissions, those with recurrent DKA were more likely to smoke (69% vs 27%, P = 0.003), be unemployed (31% vs 11%, P = 0.04) and use illicit substances (44% vs 17%, P = 0.02). There is a high prevalence of psychiatric illness, illicit substance use and social disadvantage among people admitted with DKA, particularly those with recurrent presentations. Insulin omission, often due to inappropriate sick day management, was the most common reason for DKA occurrence. Innovative multidisciplinary models of care are required to address these challenges.

A review of risk factors associated with insulin omission for weight loss in type 1 diabetes.

Research suggests that as many as 60% of people with type 1 diabetes (T1D) admit to misusing insulin. Insulin omission (IO) for the purpose of weight loss, often referred to as diabulimia, is a behaviour becoming increasingly recognised, not least since prolonged engagement can lead to serious vascular complications and mortality. Several risk factors appear to be relevant to the development of IO, most notably gender, anxiety and depression and increased weight concerns and body dissatisfaction. Evidence suggests that women, especially young girls, are more likely to omit insulin as a method of weight loss compared to men. Mental health conditions such as anxiety and depression are increasingly prevalent in people with T1D compared to their peers, and appear to contribute to the risk of IO. Increased weight concerns and body dissatisfaction are further prominent risk factors, especially given increases in weight which often occur following diagnosis and the monitoring of weight by diabetes teams. This review presents evidence examining these risk factors which increase the likelihood of a person with T1D engaging in IO and highlights the complications associated with prolongment of the behaviour. Further research looking at the comorbidities of these risk factors, alongside other factors, would provide greater insight into understanding IO in people with T1D.

Hypothalamic Gliosis in Adolescents With Type 1 Diabetes and Disordered Eating Behaviors

Abstract Background: The hypothalamus and brainstem are thought to be the principal homeostatic brain areas responsible for regulating appetite and weight. Research suggests that inflammation plays a role in the onset and maintenance of eating-related maladaptive behaviors. Hypothalamic inflammation and reactive gliosis mediate disruptions in energy homeostasis, especially with obesity. Data from SEARCH in Youth for Diabetes has demonstrated high prevalence of disordered eating behaviors (DEB) including insulin omission and binge eating, in individuals with type 1 diabetes (T1D). Limited studies have used neuroimaging techniques for investigation of hypothalamic gliosis in individuals with T1D and DEB. Objectives: To determine the feasibility of assessing hypothalamic gliosis with structural MRI in adolescents with T1D with and without DEB. Research Design and Methods: Adolescents with T1D with and without DEB, aged 13–19, were invited to participate. Participants with current use of medications known to alter appetite were excluded. They completed the Diabetes Eating Problem Survey - Revised (DEPS-R). A score ≥ 20 was indicative of DEB. Height, weight and waist circumference were obtained, and BMI was calculated. HbA1c was obtained from their prior clinic visit, within 2 months of the study visit. Basal insulin (glargine) was administered the night before, and participants on insulin pump continued with their basal insulin infusion. Participants received rapid-acting insulin prior to the MRI study, and blood glucoses were measured before and after the MRI. Mediobasal hypothalamic (MBH) gliosis was measured by T2 relaxation time. Results: Eight subjects (50% female, mean age 17.8±2.3 years) have completed the study without adverse outcomes. Mean HbA1c was 8.5% (range 7.3–10%). Five subjects screened positive for DEB. There was no significant difference in BMI between DEB and non-DEB groups. In this cohort, females had longer T2 relaxation times in left MBH than males (p=0.035). Compared to non-DEB group, participants with DEB had longer T2 relaxation time in left MBH, adjusted for sex and age (p=0.001). In this initial sample, relationships between MBH T2 relaxation times and glycemic control, BMI or waist circumference did not emerge. Conclusion: The study protocol with insulin injection and MRI to study the hypothalamic gliosis in individuals with T1D is feasible. Structural MRI indicates increased T2 relaxation times as a marker of hypothalamic gliosis in participants with DEB. Further studies with larger sample size are crucial to validate these findings and to study specific eating behaviors and their associations with MBH gliosis in individuals with T1D.

Profile of diabetic ketoacidosis at the National Diabetes and Endocrine Center in Tripoli, Libya, 2015

BackgroundDiabetic ketoacidosis (DKA) is a major acute metabolic complication of type I diabetes mellitus but may occur in type II diabetes during severe stressful conditions. AimThe aim of this study was to describe the clinical profile of DKA patients admitted to the National Diabetes and Endocrine Center in Tripoli, Libya, during 2015. Patients and methodsThe profiles of 490 patients admitted with DKA were retrospectively studied. All the data was collected from the patient files. ResultsMost of the patients (91.6%) were admitted to the intensive care unit. The mean age was 35.9 years. DKA was more common among young males with type I diabetes. The average duration of diabetes disease of the patient when admitted with DKA was 16.8 ± 8.2 years. The frequencies of patients admitted with mild, moderate or severe diabetic ketoacidosis were 49.8%, 32.7% and 17.8%, respectively. The most frequent causes of admission were insulin omission (21.8%), infection (20.2%), and wrong dose (11%). The cause of DKA was not known for 29.8% of the patients. DKA was more common among young males, and the rate increased with longer duration of the condition. Most of the patients (93.1%) were discharged in good health, and mortality was 0.6%. ConclusionMales and patients with a long duration of diabetes disease are more prone to develop DKA. The common causes of DKA were unknown in our study; however, admission of individuals with less serious illness, insulin omission, and infection may contribute to the development of DKA.
