This study asked whether the energetic properties of muscles are changed by insulin-dependent diabetes mellitus (or type 1 diabetes), as occurs in obesity and type 2 diabetes. We used 31P magnetic resonance spectroscopy to measure glycolytic flux, oxidative flux, and contractile cost in the ankle dorsiflexor muscles of 10 men with well-managed type 1 diabetes and 10 age- and activity-matched control subjects. Each subject performed sustained isometric muscle contractions lasting 30 and 120 s while attempting to maintain 70–75% of maximal voluntary contraction force. An altered glycolytic flux in type 1 diabetic subjects relative to control subjects was apparent from significant differences in pH in muscle at rest and at the end of the 120-s bout. Glycolytic flux during exercise began earlier and reached a higher peak rate in diabetic patients than in control subjects. A reduced oxidative capacity in the diabetic patients' muscles was evident from a significantly slower phosphocreatine recovery from a 30-s exercise bout. Our findings represent the first characterization of the energetic properties of muscle from type 1 diabetic patients. The observed changes in glycolytic and oxidative fluxes suggest a diabetes-induced shift in the metabolic profile of muscle, consistent with studies of obesity and type 2 diabetes that point to common muscle adaptations in these diseases.

Abstract Objectives: The aim of the study was to calculate the prevalence rates and risk ofappearance of cutaneous lesions in diabetic patients with both type-1 and type-2diabetes. Material and Method: 384 patients were analysed, of which 47 had type-1diabetes (T1DM), 140 had type-2 diabetes (T2DM) and 197 were non-diabeticcontrols. Results: The prevalence of the skin lesions considered markers of diabeteswas 57.75% in diabetics, in comparison to 8.12% in non-diabetics (p<0.01). The riskof skin lesion appearance is over 7 times higher in diabetic patients than in nondiabetics.In type-1 diabetes the prevalence of skin lesions was significantly higherthan in type-2 diabetes, and the risk of skin lesion appearance is almost 1.5 timeshigher in type-1 diabetes than type-2 diabetes compared to non-diabetic controls.Conclusions: The diabetic patients are more susceptible than non-diabetics todevelop specific skin diseases. Patients with type-1 diabetes are more affected.

ABSTRACT Whereas the genetic risk for type 1 diabetes is linked to human leukocyte antigen (HLA) class II genes, the HLA association in type 2 (non-insulin-dependent) diabetes is less clear. The association between HLA class II genotypes and type 2 diabetes was examined in adult Bahrainis, an Arab population with a high prevalence of type 2 diabetes. HLA-DRB1* and -DQB1* genotyping of 86 unrelated type 2 diabetes patients (age, 51.6 ± 8.2 years; mean duration of diabetes, 7.7 ± 7.1 years) who had a strong family history of diabetes (52 of 72 versus 0 of 89 for controls, P < 0.001) and 89 healthy subjects was done by PCR-sequence-specific priming. DRB1*040101 (0.1221 versus 0.0562, P = 0.019) and DRB1*070101 (0.2151 versus 0.0843, P < 0.001) were positively associated, while DRB1*110101 (0.0698 versus 0.1461, P = 0.014) and DRB1*160101 (0.0640 versus 0.1236, P = 0.038) were negatively associated with type 2 diabetes. DRB1*040101-DQB1*0302 (0.069 versus 0.0007; P = 0.004), DRB1*070101-DQB1*0201 (0.178 versus 0.0761, P = 0.007), DRB1*070101-DQB1*050101 (0.125 versus 0.0310, P = 0.002), and DRB1*150101-DQB1*060101 (0.0756 versus 0.0281, P = 0.008) were more prevalent among patients, while DRB1*160101-DQB1*050101 (0.0702 versus 0.0349, P = 0.05) was more prevalent among controls, conferring disease susceptibility or protection, respectively. In Bahrainis with type 2 diabetes, there is a significant association with select HLA class II genotypes, which were distinct from those in type 1 diabetes.

ObjectiveInsulin-dependent diabetes can occur with immune checkpoint inhibitor (ICI) therapy. We aimed to characterize the frequency, natural history and potential predictors of ICI-induced diabetes.Research design and methodsWe reviewed 1444 patients treated with ICIs over 6 years at our cancer center, and from the 1163 patients who received programmed cell death protein 1 (PD-1) inhibitors, we identified 21 such cases, 12 of which developed new-onset insulin-dependent diabetes and 9 experienced worsening of pre-existing type 2 diabetes.ResultsICI-induced diabetes occurred most frequently with pembrolizumab (2.2%) compared with nivolumab (1%) and ipilimumab (0%). The median age was 61 years, and body mass index was 31 kg/m2, which are both higher than expected for spontaneous type 1 diabetes. Other immune-related adverse events occurred in 62%, the most common being immune mediated thyroid disease. New-onset insulin-dependent diabetes developed after a median of four cycles or 5 months; 67% presented with diabetic ketoacidosis and 83% with low or undetectable C-peptide. Autoantibodies were elevated in 5/7 (71%) at the time of new-onset diabetes. Diabetes did not resolve during a median follow-up of 1 year.ConclusionsPD-1 inhibitors can lead to insulin deficiency presenting as new-onset diabetes or worsening of pre-existing type 2 diabetes, with a frequency of 1.8 %. The underlying mechanism appears similar to spontaneous type 1 diabetes but there is a faster progression to severe insulin deficiency. Better characterization of ICI-induced diabetes will improve patient care and enhance our understanding of immune-mediated diabetes.

Risk Of Death

The long-term complications of diabetes mellitus include retinopathy, nephropathy, and neuropathy. Diabetic retinopathy can result in loss of vision; nephropathy may lead to end-stage kidney disease (ESKD); and neuropathy poses the risk of foot ulcers, amputation, Charcot joints, sexual dysfunction, and potentially disabling dysfunction of the stomach, bowel, and bladder. Hyperglycemia sufficient to cause pathologic and functional changes in target tissues may be present for some time before clinical symptoms lead to a diagnosis of diabetes, especially in patients with type 2 diabetes. Diabetic patients are also at increased risk for atherosclerotic cardiovascular, peripheral vascular, and cerebrovascular disease. These conditions may be related to hyperglycemia, as well as to the hypertension and abnormal lipoprotein profiles that are often found in diabetic patients. Prevention of these complications is a major goal of current therapeutic policy and recommendations for all but transient forms of diabetes. This chapter describes the pathogenesis, screening, prevention, and treatment of diabetic complications, as well as the management of hyperglycemia in the hospitalized patient. Figures illustrate the pathways that link high blood glucose levels to microvascular and macrovascular complications; fundus abnormalities in diabetic retinopathy; the natural history of nephropathy in type 1 diabetes; cumulative incidence of first cardiovascular events, stroke, or death from cardiovascular disease in patients with type 1 diabetes; the effect of intensive glycemic therapy on the risk of myocardial infarction, major cardiovascular event, or cardiovascular death in patients with type 2 diabetes; and risk of death in patients with type 2 diabetes who receive intensive therapy of multiple risk factors or conventional therapy. Tables describe screening schedules for diabetic complications in adults, foot care recommendations for patients with diabetes, and comparison of major trials of intensive glucose control.

Butyrylcholinesterase Activity

1. The activity of serum butyrylcholinesterase (‘pseudocholinesterase’, EC3.1.1.8) was investigated in 56 patients with type 1 diabetes mellitus, 51 patients with type 2 diabetes mellitus and 101 healthy control subjects. 2. Butyrylcholinesterase activity was significantly elevated in both type 1 (8.10 ± 3.35 units/ml) and type 2 (7.22 ± 1.95 units/ml) diabetes compared with the control subjects (4.23 ± 1.89 units/ml) (P <0.001). 3. In the patients with type 1 and type 2 diabetes, serum butyrylcholinesterase activity was correlated with log serum fasting triacylglycerol concentration (r = 0.41 and r = 0.43, respectively, P <0.001). In the type 2 population serum butyrylcholinesterase activity was also correlated with insulin sensitivity (r = −0.51, P <0.001). 4. Serum butyrylcholinesterase activity was unrelated to age, gender, serum γ-glutamyltranspeptidase activity, body mass index, or treatment for diabetes in both the diabetic populations. 5. In 37 non-diabetic patients with butyrylcholinesterase deficiency serum triacylglycerol levels were in the normal range. 6. These results are consistent with the view that butyrylcholinesterase may have a role in the altered lipoprotein metabolism in hypertriglyceridaemia associated with insulin insensitivity or insulin deficiency in diabetes mellitus.

Background: Diabetic neuropathy is defined as the dysfunction of the peripheral nervous system in diabetic patients. It is considered a microvascular complication of diabetes mellitus. Its presence is associated with increased morbidity and mortality. Although several studies have found alterations at somatic motor, sensory levels and at the level of autonomic nervous system in diabetic patients, there is not a systematic approach regarding the differences in neuropathy between the major variants of diabetes, e.g., type 1 and 2 diabetes at both neurological and molecular level. Data sources: we systematically (Medline, Scopus, and Cochrane databases) evaluated the literature related to the difference of neuropathy in type 1 and 2 diabetes, differences in molecular biomarkers. Study characteristics: seventeen articles were selected based on pre-defined eligibility criteria. Conclusions: both superficial sensitivity (primarily thermal sensitivity to cold) and deep sensitivity (such as vibratory sensitivity), have been reported mainly in type 2 diabetes. Cardiac autonomic neuropathy is one of the diabetic complications with the greatest impact at a clinical level but is nevertheless one of the most underdiagnosed. While for type 1 diabetes patients most neuropathy alterations have been reported for the Valsalva maneuver and for the lying-to-standing test, for type 2 diabetes patients, alterations have been reported for deep-breathing test and the Valsalva test. In addition, there is a greater sympathetic than parasympathetic impairment, as indicated by the screening tests for autonomic cardiac neuropathy. Regarding subclinical inflammation markers, patients with type 2 diabetes showed higher blood levels of inflammatory markers such as high-sensitivity C-reactive protein, proinflammatory cytokines IL-6, IL-18, soluble cell adhesion molecules and E-selectin and ICAM-1, than in type 1 diabetes patients. By contrast, the blood levels of adiponectin, an adipocyte-derived protein with multiple paracrine and endocrine activities (anti-inflammatory, insulin-sensitizing and proangiogenic effects) are higher in type 1 than in type 2 diabetic patients. This review provides new insights into the clinical differences in type 1 and 2 diabetes and provide future directions in this research field.

AimsTo determine the characteristics of adult patients referred to a Liaison Psychiatry service in a general teaching hospital in London, UK with 950 inpatient adult beds.MethodAll referrals for adult inpatient psychiatric consultation made during a period of 9 months were reviewed; those that involved a patient with a diagnosis of diabetes were analysed. Descriptive statistics were used; data were collected on demographic characteristics and physical and mental health parameters, including type of diabetes, number of years since diabetes diagnosis, glycaemic control, presence of diabetes-related complications, reason for Psychiatry consultation request, psychiatric diagnosis, psychotropic medication, frequency of admissions to general hospital, psychiatric risk issues and outcome of psychiatric consultation.ResultPilot results indicate that 30 diabetic patients were referred for a psychiatric consultation in 9 months. Of those, 9 had type 1 diabetes, 17 had type 2 diabetes and 1had pre-diabetes 3 were unknown. 13 were male and 17 were female; the median age was 46 (range 18 to 68); the ethnicities were 6 White, 15 Black, 1 Asian and 8 other.Diabetes-related complications were present in 77% (retinopathy 10%, kidney disease 27%, neuropathy 13%, diabetic foot 16%). 6% had comorbid cardiovascular disease. 10% were on dialysis and 3% had had amputations.The main reason for referral for psychiatric consultation was low mood and self harm; other reasons were recurrent DKA, anxiety and self neglect. Psychiatric risk issues included 20% risk of self-harm/suicide; 13% risk of violence; 10 risk of self-neglect. The outcomes of liaison psychiatry consultation were: 30% received an assessment that led to recommendations to the general medical team and did not require further psychiatric input; 27% received continued psychiatric follow-up during the admission. With regards to treatment, 36% had psychiatric treatment (including medication) reviewed; 47% received general treatment recommendations, including recommendations for new laboratory or radiological investigations or change in level of nursing care. 20% required transfer to an inpatient psychiatric unit, with 33% discharged to care of community mental health.ConclusionOur findings indicate the scope of practice for a Liaison Psychiatry service with regards to adult hospital inpatients with diabetes. Our data suggest that patients with type 2 diabetes are the majority of inpatients with diabetes that require psychiatric consultations, and that the majority of those are patients already known to psychiatric services due to long-term severe mental disorders, particularly schizophrenia, schizoaffective disorder or bipolar disorder. Most of those patients have medical comorbidities and severe diabetes-related complications. Patients with type 1 diabetes, despite making up a smaller proportion of referrals for psychiatric consultations, also tend to have recurrent hospital admissions and features of self-neglect.

A 19-year-old female with type 1 diabetes for four years, and a 73-year-old female with type 2 diabetes for twenty years developed sudden-onset nephrotic syndrome. Examination by light microscopy, immunofluorescence, and electron microscopy (in one case) identified minimal change disease (MCD) in both cases. There was a potential causative drug (meloxicam) for the 73-year-old patient. Both patients were treated with prednisone and responded with complete remission. The patient with type 1 diabetes showed complete remission without relapse, and the patient with type 2 diabetes had two relapses; complete remission was sustained after associated treatment with cyclophosphamide and prednisone. Both patients had two years of follow-up evaluation after remission. We discuss the outcomes of both patients and emphasize the role of kidney biopsy in diabetic patients with an atypical proteinuric clinical course, because patients with MCD clearly respond to corticotherapy alone or in conjunction with other immunosuppressive agents.

The first use of insulin in 1922 began a new era in the management and survival of patients with type 1 diabetes. Before 1922, patients with this condition were placed on a starvation diet and survived only a few months. Nearly a century later, insulin remains the dominant treatment for type 1 diabetes, is used in gestational diabetes and increasingly in type 2 diabetes. This article focuses on insulin treatment for adult diabetic patients in general practice. It will explore the effect of insulin and the role it has in diabetes, the preparations available, recommended regimens and some challenges with insulin treatment.

AbstractMaturity-onset diabetes of the young (MODY) is a group of monogenic disorders characterized by autosomal dominantly inherited non-insulin dependent form of diabetes classically presenting in adolescence or young adults before the age of 25 years. MODY is a rare cause of diabetes (1% of all cases) and is frequently misdiagnosed as Type 1 diabetes (T1DM) or Type 2 diabetes (T2DM). A precise molecular diagnosis is essential because it leads to optimal treatment of the patients and allows early diagnosis for their asymptomatic family members. Mutations in the glucokinase (
