Psychosocial factors associated with repeat diabetic ketoacidosis in people living with type 1 diabetes: A systematic review.

AIM: To systematically review the literature concerning the psychosocial factors associated with repeat diabetic ketoacidosis for people living with type 1 diabetes. METHODS: PsycInfo, Web of Science, CINAHL, PubMed and ASSIA were searched according to a registered study protocol (PROSPERO CRD42020167381). Data were extracted into a coding spreadsheet, and findings were synthesised narratively. Included papers were also subject to a quality assessment. RESULTS: The search yielded 548 unique articles, of which 22 met inclusion criteria for this review. There was considerable variance across studies with regard to design, quality and outcome measured. Nevertheless, there was relatively consistent evidence to suggest that repeat diabetic ketoacidosis in type 1 diabetes is associated with female gender, adolescent to young adult age range, lower socio-economic status and poor mental health. Some evidence was also observed for the role of ethnicity and, for children and young people at least, family, social and behavioural issues. However, this was limited by issues of methodological rigour and scant investigation. CONCLUSIONS: The review identified four psychosocial factors that appear to play a key role in the cycle of repeat diabetic ketoacidosis. Individuals with these factors present may benefit from targeted support and interventions by specialist healthcare professionals. Knowledge and understanding in this area would be considerably enhanced via increased use of prospective study designs and greater consistency in the operationalisation of variables across studies.

Diabetic ketoacidosis: a canary in the mine for mental health disorders?

BACKGROUND: Recurrent diabetic ketoacidosis (DKA) has been linked to mental health disorders, but less is known about single DKA episodes. Most studies are retrospective, lacking control groups. AIMS: To prospectively examine psychosocial factors in patients presenting with recurrent or single episode DKA and compare with people who have not had DKA. METHODS: Case-controlled study (consecutive adult DKA admissions April 2015 to December 2016) at Western Health, Melbourne. Data were prospectively collected regarding diagnosed mental health disorders, likely depression (Patient Health Questionnaire (PHQ-9)), diabetes distress (Problem Areas in Diabetes (PAID) questionnaire) and presence of adverse social factors. A control group without a history of DKA was also recruited. RESULTS: Of 123 patients admitted with DKA (164 consecutive episodes), 70 consented to participate and 73 age-matched Type 1 diabetes controls were recruited. Eleven (61%) of 18 with recurrent DKA had a diagnosed mental health disorder versus 8 (19%) of 42 in the single episode group (P = 0.016). The prevalence of likely depression using PHQ-9 was: recurrent 50%; single 40%; and controls 22% (recurrent vs controls, P = 0.036; single vs controls, P = 0.053). Severe diabetes distress (PAID) was present in 47% of recurrent and 34% of single episode DKA (P = 0.387). As a group, DKA patients had significantly more unemployment, illicit drug use and tobacco smoking, a lower level of formal education and less regular medical contact compared with controls. CONCLUSIONS: Mental health disorders and adverse socioeconomic factors appear to be common in patients with DKA. The diagnosis of DKA presents an excellent opportunity to screen for depression and offer appropriate intervention.

The psychopathology of recurrent diabetic ketoacidosis: A case-control study.

BACKGROUND: Despite its poor prognosis, the psychological factors associated with recurrent diabetic ketoacidosis are poorly understood. In people with type 1 diabetes, we assessed for psychopathology in those with and without recurrent diabetic ketoacidosis (DKA). METHOD: The design was a case-control study. Cases were defined as people with two or more DKA episodes in a 12-month period (recurrent DKA). Cases and controls were matched for gender and age. We compared groups for scores on Beck's Anxiety Inventory (BAI), Beck's Depression Inventory II, Difficulty in Emotion Regulation Scale (DERS), Experiences in Close Relationships-Revised, Standardised Assessment of Personality-Abbreviated Scale (SAPAS), Interpersonal Problem Inventory, Eating Disorder Examination Questionnaire and Problem Areas in Diabetes (PAID) using unpaired t-tests or Mann-Whitney U tests for parametric and non-parametric data, respectively. Correction was made for multiple testing. RESULTS: In all, 23 cases and 23 controls were recruited with mean age 31.0 (11.4) years and 65.2% were men. Cases had higher HbA1c levels than controls (101.1 (23.2) vs. 85.7 (21.7) mmol/mol, (p = 0.02)). Compared to controls, people with recurrent DKA had higher scores on the BAI (p = 0.004), PAID (p = 0.004), DERS (p = 0.001) and SAPAS (p < 0.001). Sixteen of 23 (69.6%) cases screened positive for a personality disorder compared to 6 of 23 (26.1%) controls. CONCLUSIONS: People with recurrent DKA have elevated levels of anxiety and diabetes distress, greater difficulty with emotion regulation and personality dysfunction compared to matched controls.

Cognitive Function Following Diabetic Ketoacidosis in Children With New-Onset or Previously Diagnosed Type 1 Diabetes.

OBJECTIVE: This study assessed whether a single diabetic ketoacidosis (DKA) episode is associated with cognitive declines in children with newly diagnosed type 1 diabetes and whether the same is true in children who had previously been diagnosed after accounting for variations in glycemic control and other relevant factors. RESEARCH DESIGN AND METHODS: We prospectively enrolled 758 children, 6-18 years old, who presented with DKA in a randomized multisite clinical trial evaluating intravenous fluid protocols for DKA treatment. DKA was moderate/severe in 430 children and mild in 328 children. A total of 392 children with DKA had new onset of type 1 diabetes, and the rest were previously diagnosed. Neurocognitive assessment occurred 2-6 months after the DKA episode. A comparison group of 376 children with type 1 diabetes, but no DKA exposure, was also enrolled. RESULTS: Among all patients, moderate/severe DKA was associated with lower intelligence quotient (IQ) (ß = -0.12, P < 0.001), item-color recall (ß = -0.08, P = 0.010), and forward digit span (ß = -0.06, P = 0.04). Among newly diagnosed patients, moderate/severe DKA was associated with lower item-color recall (ß = -0.08, P = 0.04). Among previously diagnosed patients, repeated DKA exposure and higher HbA1c were independently associated with lower IQ (ß = -0.10 and ß = -0.09, respectively, P < 0.01) and higher HbA1c was associated with lower item-color recall (ß = -0.10, P = 0.007) after hypoglycemia, diabetes duration, and socioeconomic status were accounted for. CONCLUSIONS: A single DKA episode is associated with subtle memory declines soon after type 1 diabetes diagnosis. Sizable IQ declines are detectable in children with known diabetes, suggesting that DKA effects may be exacerbated in children with chronic exposure to hyperglycemia.

Effect of Flash Glucose Monitoring on Glycemic Control, Hypoglycemia, Diabetes-Related Distress, and Resource Utilization in the Association of British Clinical Diabetologists (ABCD) Nationwide Audit.

OBJECTIVE: The FreeStyle Libre (FSL) flash glucose-monitoring device was made available on the U.K. National Health Service (NHS) drug tariff in 2017. This study aims to explore the U.K. real-world experience of FSL and the impact on glycemic control, hypoglycemia, diabetes-related distress, and hospital admissions. RESEARCH DESIGN AND METHODS: Clinicians from 102 NHS hospitals in the U.K. submitted FSL user data, collected during routine clinical care, to a secure web-based tool held within the NHS N3 network. The t and Mann-Whitney U tests were used to compare the baseline and follow-up HbA1c and other baseline demographic characteristics. Linear regression analysis was used to identify predictors of change in HbA1c following the use of FSL. Within-person variations of HbA1c were calculated using [Formula: see text]. RESULTS: Data were available for 10,370 FSL users (97% with type 1 diabetes), age 38.0 (±18.8) years, 51% female, diabetes duration 16.0 (±49.9) years, and BMI of 25.2 (±16.5) kg/m2 (mean [±SD]). FSL users demonstrated a -5.2 mmol/mol change in HbA1c, reducing from 67.5 (±20.9) mmol/mol (8.3%) at baseline to 62.3 (±18.5) mmol/mol (7.8%) after 7.5 (interquartile range 3.4-7.8) months of follow-up (n = 3,182) (P < 0.0001). HbA1c reduction was greater in those with initial HbA1c ≥69.5 mmol/mol (>8.5%), reducing from 85.5 (±16.1) mmol/mol (10%) to 73.1 (±15.8) mmol/mol (8.8%) (P < 0.0001). The baseline Gold score (score for hypoglycemic unawareness) was 2.7 (±1.8) and reduced to 2.4 (±1.7) (P < 0.0001) at follow-up. A total of 53% of those with a Gold score of ≥4 at baseline had a score <4 at follow-up. FSL use was also associated with a reduction in diabetes distress (P < 0.0001). FSL use was associated with a significant reduction in paramedic callouts and hospital admissions due to hypoglycemia and hyperglycemia/diabetic ketoacidosis. CONCLUSIONS: We show that the use of FSL was associated with significantly improved glycemic control and hypoglycemia awareness and a reduction in hospital admissions.

Effects of Diabetic Ketoacidosis on Executive Function in Children With Type 1 Diabetes: Evidence From Wisconsin Card Sorting Test Performance.

OBJECTIVE: Diabetic ketoacidosis (DKA) in patients with type 1 diabetes mellitus (T1DM) is known to affect memory function, but little is known about its impact on executive function. This study aimed to determine whether a history of DKA was associated with changes in executive function in children with T1DM. METHODS: The sample consisted of 99 patients with T1DM with histories of DKA, 82 patients with T1DM without DKA, and 100 healthy controls aged 7 to 18 years. Neuropsychological function and emotion assessments were performed in all participants. The Wisconsin Card Sorting Test (WCST) was used to assess executive function. RESULTS: Compared with healthy controls, the DKA group (but not the non-DKA group) had a significantly lower mean intelligence quotient (IQ; p = .006, Cohen d = 0.528) and a significantly higher rate of WCST perseverative errors (p = .006, Cohen d = 0.475). In the DKA group, the age at DKA onset was significantly associated with the IQ (p = .001) and the number of completed WCST categories (p = .046). Higher hemoglobin A1c levels were associated significantly with lower IQ (p < .001), increased rate of WCST perseverative errors (p = .015), and completion of fewer WCST categories (p = .027). CONCLUSIONS: DKA has implications for executive function in children with T1DM. These findings emphasize the importance of DKA prevention in patients with known T1DM, especially younger children with newly diagnosed T1DM.

Recurrent diabetic ketoacidosis and a brief history of brittle diabetes research: contemporary and past evidence in diabetic ketoacidosis research including mortality, mental health and prevention.

Pharmacological, technological and educational approaches have advanced the treatment of Type 1 diabetes in the last four decades and yet diabetic ketoacidosis (DKA) continues to be a leading cause of admission in Type 1 diabetes. This article begins by reviewing the contemporary epidemiological evidence in DKA. It highlights a rise in DKA episodes in the last two decades, with DKA continuing to be the leading cause of death in young people with Type 1 diabetes, and that DKA episodes are a marker for subsequent all-cause mortality. It also summarizes the limited evidence base for DKA prevention and associations with psychopathology. To emphasize the importance of this group with high-risk Type 1 diabetes and the degree to which they have been overlooked in the past two decades, the article summarizes the research literature of recurrent DKA during 1976-1991 when it was extensively investigated as part of the phenomenon of 'brittle diabetes'. This period saw numerous basic science studies investigating the pathophysiology of recurrent DKA. Subsequently, research centres published their experiences of brittle diabetes research participants manipulating their treatment under research conditions. Unfortunately, the driver for this behaviour and whether it was indicative of other people with ketoacidosis was not pursued. In summary, we suggest there has been a stasis in the approach to recurrent DKA prevention, which is likely linked to historical cases of mass sabotage of brittle diabetes research. Further investigation is required to clarify possible psychological characteristics that increase the risk of DKA and thereby targets for DKA prevention.

Characteristics of young adults with multiple episodes of diabetic ketoacidosis.

Transition from paediatric to adult diabetes care can be associated with a deterioration in metabolic control and hospitalisation. This was a retrospective review (2012-2016) of medical records of all patients attending a transition diabetes clinic in a teaching hospital with paediatric and adult diabetes on the same site. Among the 91/102 (89.2%) patients with type 1 diabetes, mean age at first visit was 19 ± 2 years, last body mass index was 25.2 ± 4.7 kg/m2 , diabetes duration was 11 ± 6 years and 22 (24%) used continuous subcutaneous insulin infusions. Loss to follow-up was 15 (14.7%). Mental health issues were common (59%), as were prior pregnancies (23%) and diabetic ketoacidosis since diagnosis (39%). Those with diabetic ketoacidosis had a higher mean glycated haemoglobin (70 ± 19 vs 86 ± 25 mmol/mol or 8.6 ± 1.7 vs 10.0 ± 2.3%; P = 0.001), fewer clinic attendances (8 ± 5 vs 5 ± 4; P = 0.008) and fewer years in clinic (1.8 ± 1.7 vs 2.3 ± 1.4; P = 0.114). Our data suggest that investment in joint approaches with mental health services should be considered.

Exploring Patient Preferences for Adjunct-to-Insulin Therapy in Type 1 Diabetes.

OBJECTIVE: While sodium-glucose cotransporter inhibitor (SGLTi) therapy has been evaluated in type 1 diabetes (T1D) trials, patient reactions to benefits and risks are unknown. Using established methodology, we evaluated patient preferences for different adjunct-to-insulin therapy options in T1D. RESEARCH DESIGN AND METHODS: An online survey, completed by 701 respondents with T1D (231 U.S., 242 Canada, and 228 Germany), used conjoint analysis to present six hypothetical, masked, pairwise drug profile choices composed of different benefit-risk attributes and effect ranges. Data used in analyses were derived from actual phase 3 trials of a low-dose SGLTi (comparable to oral empagliflozin 2.5 mg q.d.), a high-dose SGLTi (comparable to oral sotagliflozin 400 mg q.d.), and an available adjunct-to-insulin therapy (comparable to subcutaneous pramlintide 60 µg t.i.d.). RESULTS: Conjoint analysis identified diabetic ketoacidosis risk as most important to patients (23% relative score; z test, P < 0.05); ranked second were HbA1c reduction (14%), risk of severe hypoglycemia (13%), oral versus injectable treatment (12%), and risk of genital infection (12%). Next was risk of nausea (11%), followed by weight reduction (8%) and the risk of diarrhea (7%). A low-dose SGLTi drug profile was identified by conjoint analysis as the top patient preference (83% of participants; z test, P < 0.05) versus high-dose SGLTi (8%) or pramlintide (9%). Separate from conjoint analysis, when respondents were asked to choose their preferred adjunct-to-insulin therapy (masked to drug name/dose), 69%, 17%, 6%, and 9% of respondents chose low-dose SGLTi, high-dose SGLTi, pramlintide, and insulin therapy alone, respectively. CONCLUSIONS: Low-dose SGLTi profile was the favored adjunct-to-insulin therapy by persons with T1D.

Impact of Early Diabetic Ketoacidosis on the Developing Brain.

OBJECTIVE: This study examined whether a history of diabetic ketoacidosis (DKA) is associated with changes in longitudinal cognitive and brain development in young children with type 1 diabetes. RESEARCH DESIGN AND METHODS: Cognitive and brain imaging data were analyzed from 144 children with type 1 diabetes, ages 4 to <10 years, who participated in an observational study of the Diabetes Research in Children Network (DirecNet). Participants were grouped according to history of DKA severity (none/mild or moderate/severe). Each participant had unsedated MRI scans and cognitive testing at baseline and 18 months. RESULTS: In 48 of 51 subjects, the DKA event occurred at the time of onset, at an average of 2.9 years before study entry. The moderate/severe DKA group gained more total and regional white and gray matter volume over the observed 18 months compared with the none/mild group. When matched by age at time of enrollment and average HbA1c during the 18-month interval, participants who had a history of moderate/severe DKA compared with none/mild DKA were observed to have significantly lower Full Scale Intelligence Quotient scores and cognitive performance on the Detectability and Commission subtests of the Conners' Continuous Performance Test II and the Dot Locations subtest of the Children's Memory Scale. CONCLUSIONS: A single episode of moderate/severe DKA in young children at diagnosis is associated with lower cognitive scores and altered brain growth. Further studies are needed to assess whether earlier diagnosis of type 1 diabetes and prevention of DKA may reduce the long-term effect of ketoacidosis on the developing brain.

Clinical Trial of Fluid Infusion Rates for Pediatric Diabetic Ketoacidosis.

BACKGROUND: Diabetic ketoacidosis in children may cause brain injuries ranging from mild to severe. Whether intravenous fluids contribute to these injuries has been debated for decades. METHODS: We conducted a 13-center, randomized, controlled trial that examined the effects of the rate of administration and the sodium chloride content of intravenous fluids on neurologic outcomes in children with diabetic ketoacidosis. Children were randomly assigned to one of four treatment groups in a 2-by-2 factorial design (0.9% or 0.45% sodium chloride content and rapid or slow rate of administration). The primary outcome was a decline in mental status (two consecutive Glasgow Coma Scale scores of <14, on a scale ranging from 3 to 15, with lower scores indicating worse mental status) during treatment for diabetic ketoacidosis. Secondary outcomes included clinically apparent brain injury during treatment for diabetic ketoacidosis, short-term memory during treatment for diabetic ketoacidosis, and memory and IQ 2 to 6 months after recovery from diabetic ketoacidosis. RESULTS: A total of 1389 episodes of diabetic ketoacidosis were reported in 1255 children. The Glasgow Coma Scale score declined to less than 14 in 48 episodes (3.5%), and clinically apparent brain injury occurred in 12 episodes (0.9%). No significant differences among the treatment groups were observed with respect to the percentage of episodes in which the Glasgow Coma Scale score declined to below 14, the magnitude of decline in the Glasgow Coma Scale score, or the duration of time in which the Glasgow Coma Scale score was less than 14; with respect to the results of the tests of short-term memory; or with respect to the incidence of clinically apparent brain injury during treatment for diabetic ketoacidosis. Memory and IQ scores obtained after the children's recovery from diabetic ketoacidosis also did not differ significantly among the groups. Serious adverse events other than altered mental status were rare and occurred with similar frequency in all treatment groups. CONCLUSIONS: Neither the rate of administration nor the sodium chloride content of intravenous fluids significantly influenced neurologic outcomes in children with diabetic ketoacidosis.

Clinical presentation and memory function in youth with type 1 diabetes.

OBJECTIVE: While cerebral edema and diabetic ketoacidosis (DKA) in type 1 diabetes (T1DM) have well-described acute effects on cognition, little is known about the impact of clinical presentation on longer term cognitive outcomes. We hypothesized that clinical factors (degree of hyperglycemia exposure and DKA) at the time of diagnosis would relate to cognition within 3.5 months later in children with T1DM. METHODS: Cognitive testing was performed on children 7-17 years old with T1DM (n = 66) within 3.5 months of diagnosis and siblings without T1DM (n = 33). Overall intelligence, processing speed, and memory (including a sensitive long-delay spatial memory test; spatial delayed response or SDR) were assessed. Medical records were reviewed for hemoglobin A1c (HbA1c), DKA status, and other clinical factors at diagnosis. RESULTS: Within the group with T1DM, 17 children presented in DKA and 49 did not. After adjusting for age, gender, and socioeconomic status, the subgroup with T1DM and DKA at diagnosis performed worse on the long-delay SDR task compared to sibling controls (p = 0.006). In addition, within the group with T1DM, higher HbA1c at diagnosis was associated with worse performance on the long-delay SDR task (p = 0.027). Performance on the other cognitive tasks was not different across groups or subgroups. CONCLUSIONS: DKA and degree of hyperglycemia exposure at diagnosis have implications for long-delay spatial memory function within 3.5 months of diagnosis. These findings suggest that early detection of T1DM, which decreases risk for prolonged exposure to hyperglycemia and DKA, may avoid negative effects on memory function.

Risk factors for decline in IQ in youth with type 1 diabetes over the 12 years from diagnosis/illness onset.

OBJECTIVE: This study examined illness-related change in intelligence quotient (IQ) in a cohort of youth with type 1 diabetes studied prospectively from disease onset in childhood to follow-up 12 years later in late adolescence/early adulthood. RESEARCH DESIGN AND METHODS: Participants included type 1 diabetes patients (n = 95; mean age at follow-up 21.3 years) and healthy control participants (HCs; n = 67; mean age at follow-up 21.0 years) from a cohort followed prospectively. Measures included Wechsler Preschool and Primary Scale of Intelligence-Revised, Wechsler Intelligence Scale for Children-Revised, and Wechsler Abbreviated Scale of Intelligence and prospective collection of data on metabolic control history. RESULTS: Young people with type 1 diabetes showed greater decline in verbal IQ (VIQ) and full-scale IQ (FSIQ), but not performance IQ (PIQ), than HCs. Within the diabetes group, a younger age at diabetes onset was associated with a decline in PIQ and FSIQ (P ≤ 0.001). A history of hypoglycemic seizures was associated with a decline in VIQ (P = 0.002). Long-term metabolic control was not associated with changes in IQ. Interaction terms were not significant, suggesting no moderating effect of one diabetes-related variable over another. CONCLUSIONS: The presence of diabetes may negatively influence some aspects of IQ over time. Specific illness risk factors, such as an earlier age of disease onset and a history of hypoglycemic seizures, appear to put the young person at greater risk. Academic progress of children identified as at risk should be monitored and educational supports provided if necessary.

Depression in adults in the T1D Exchange Clinic Registry.

OBJECTIVE: Little is known about the frequency of depression in adults with type 1 diabetes (T1D) or its relationship to diabetes outcomes. The T1D Exchange clinic registry allowed us to explore depression in a large, heterogeneous sample. RESEARCH DESIGN AND METHODS: Participants ≥18 years old (N = 6,172; median age 34 years; median diabetes duration 16 years; 55% female; and 89% non-Hispanic white) completed the eight-item Patient Health Questionnaire (PHQ-8), a validated, reliable measure of current depression. Probable major depression was defined in four ways: PHQ-8 ≥10, PHQ-8 ≥12, per diagnostic algorithm, and as a continuous variable. Characteristics and clinical outcomes of those with and without depression were compared using logistic and linear regression models. RESULTS: A total of 4.6-10.3% of participants were classified as probable major depression depending on how defined. Participants classified as depressed were more likely female, nonwhite race/ethnicity, to have a lower household income and lower education level, to exercise less often, to miss insulin doses, and to have one or more complications (neuropathy, nephropathy, treatment for retinopathy, or cardiovascular/cerebrovascular disease) (all P < 0.01). HbA1c was higher in the depressed versus not depressed groups (8.4 ± 1.7% [68 ± 8.6 mmol/mol] vs. 7.8 ± 1.4% [62 ± 15.3 mmol/mol]; P < 0.001). Occurrence of one or more diabetic ketoacidosis events (11 vs. 4%; P < 0.001) and one or more severe hypoglycemic events (18 vs. 9%; P < 0.001) in the past 3 months was higher among depressed participants. CONCLUSIONS: In the T1D Exchange clinic registry, adults with probable major depression have worse clinical outcomes than those not depressed. Whether identification and treatment of depression improves diabetes outcomes requires study. Depression is common in T1D, and better identification and treatment of this comorbid condition is needed.

Use of the Mastery of Stress Instrument in caregivers of children newly diagnosed with type 1 diabetes: identifying a need for further intervention.

PURPOSE: The purpose of this study was to determine if the Mastery of Stress Instrument (MSI) can assess further education needs of primary caregivers of children newly diagnosed with type 1 diabetes. The MSI has been utilized to measure mastery in response to both illness and interventions, including education. The primary objective was to correlate MSI subscales and stress scores with caregiver age, ethnicity, gender, and education. Secondary objectives were to correlate MSI scores with child age at diagnosis, payer source, hemoglobin A1C (A1C), emergency room (ER) visits, or hospitalization for diabetic ketoacidosis (DKA). METHODS: Caregivers from a pediatric endocrinology practice completed the MSI after basic diabetes education. Demographic data from caregivers and patients were obtained. A1C, ER, and DKA were evaluated 2 years following completion of the MSI. Descriptive univariate statistics and proportions on nominal or discrete data were used to describe the data. Bivariable analyses included t tests and ANOVAs. RESULTS: Eighty-five of 88 participants completed the instrument. Caregivers between 40 and 49 years of age scored worse on change, acceptance, and growth subscales compared to those 18 to 29 years of age. Those 40 to 49 years of age reported having more stress compared to caregivers 18 to 29 years of age. Males reported having less stress and were more willing to implement change compared to females. No statistically significant relationships between secondary outcomes measurements and MSI scores were detected. CONCLUSIONS: The mastery of stress instrument identified groups of caregivers in need of further education or team interventions.

Eating disorders and diabetic ketoacidosis in a pregnant woman with type 1 diabetes: a case report.

OBJECTIVE: To describe a case of diabetic ketoacidosis (DKA) in a pregnant woman with type 1 diabetes (T1DM) and disordered eating behaviour treated with a continuous subcutaneous insulin infusion, and to discuss some aspects of the monitoring and management of DKA in pregnancy and whether a pump is the safest therapeutic choice in the presence of some eating disorders. CASE REPORT: This 26-year-old Caucasian woman affected by T1DM was hospitalised during the last weeks of her fourth pregnancy because of DKA due to disordered eating. She was treated with a fluid infusion, intravenous insulin, and her electrolyte imbalance was carefully corrected. An elective cesarean section was performed after the correction of DKA in the 34th week (+6 days) of gestation. CONCLUSIONS: We suggest that pregnancy in T1DM women with eating disorders may not be rare. The prevention, early recognition and aggressive management of DKA can minimise the possible complications, and is mandatory for the safety of the fetus and mother.

Recurrent diabetic ketoacidosis in inner-city minority patients: behavioral, socioeconomic, and psychosocial factors.

OBJECTIVE: To conduct a bedside study to determine the factors driving insulin noncompliance in inner-city patients with recurrent diabetic ketoacidosis (DKA). RESEARCH DESIGN AND METHODS: We analyzed socioeconomic and psychological factors in 164 adult patients with DKA who were admitted to Grady Hospital between July 2007 and August 2010, including demographics, diabetes treatment, education, and mental illness. The Patient Health Questionnaire-9 and the Short Form-36 surveys were used to screen for depression and assess quality of life. RESULTS: The average number of admissions was 4.5 ± 7 per patient. A total of 73 patients presented with first-time DKA, and 91 presented with recurrent DKA; 96% of patients were African American. Insulin discontinuation was the leading precipitating cause in 68% of patients; other causes were new-onset diabetes (10%), infection (15%), medical illness (4%), and undetermined causes (3%). Among those who stopped insulin, 32% gave no reasons for stopping, 27% reported lack of money to buy insulin, 19% felt sick, 15% were away from their supply, and 5% were stretching insulin. Compared with first-time DKA, those with recurrent episodes had longer duration of diabetes (P < 0.001), were a younger age at the onset of diabetes (P = 0.04), and had higher rates of depression (P = 0.04), alcohol (P = 0.047) and drug (P < 0.001) abuse, and homelessness (P = 0.005). There were no differences in quality-of-life scores, major psychiatric illnesses, or employment between groups. CONCLUSIONS: Poor adherence to insulin therapy is the leading cause of recurrent DKA in inner-city patients. Several behavioral, socioeconomic, psychosocial, and educational factors contribute to poor compliance. The recognition of such factors and the institution of culturally appropriate interventions and education programs might reduce DKA recurrence in minority populations.

Determinants of altered sensorium at presentation with diabetic ketoacidosis.

AIM: The aim of this paper was to determine the prevalence of altered sensorium and their determinants in diabetic ketoacidosis (DKA). METHODS: Retrospective review of medical records for diabetic ketoacidosis admissions over a two year period. RESULTS: A total of 94 admissions for DKA in 89 patients were reviewed. Majority of admissions were female related. The mean age of the subjects was 39.1±18.5 years. The prevalence of altered sensorium defined as Glasgow coma scale (GCS) below 15 was 47.9%. In Model 1, systolic blood pressure (SBP) <90 mmHg (odds ratio [OR] 17.5 95% Confidence Interval (CI) 2.1-142.9; P=0.008 and calculated effective serum osmolality >320 mosmol/Kg (OR 3.6 95% CI 1.4-12.2; P=0.043 were independently associated with altered sensorium. In Model 2 where serum osmolality was substituted with uncorrected serum sodium, SBP <90 mmHg OR 19.6 95% CI 2.2-100; P=0.007, uncorrected serum sodium >150 mmol/L OR 18.5 95% CI 2.1-100; P=0.0009 and white cell count >25 x 106/L OR 3.6 95% CI 1.03-13.5; P=0.05 were independently associated with altered sensorium. CONCLUSION: Systolic blood pressure <90 mmHg, calculated effective serum osmolality >320 mosmol/Kg, uncorrected serum sodium >150 mmol/L and white bood count >25 x 106/L were independently associated with altered sensorium.

Is salt, vitamin, or endocrinopathy causing this encephalopathy? A review of endocrine and metabolic causes of altered level of consciousness.

Altered level of consciousness describes the reason for 3% of critical emergency department (ED) visits. Approximately 85% will be found to have a metabolic or systemic cause. Early laboratory studies such as a bedside glucose test, serum electrolytes, or a urine dipstick test often direct the ED provider toward endocrine or metabolic causes. This article examines common endocrine and metabolic causes of altered mentation in the ED via sections dedicated to endocrine-, electrolyte-, metabolic acidosis-, and metabolism-related causes.
