Exogenous Insulin Antibody Syndrome (EIAS) Presenting in an Elderly, Long-Term Patient with Type 1 Diabetes Mellitus that Resolved with Low-Cost Outpatient Therapy with Mycophenolate Mofetil and Regular Insulin by Pump.

Exogenous insulin antibody syndrome (EIAS) has until recently been a rarely described complication of exogenous insulin therapy. EIAS results not only in hyperglycemia, but also in hypoglycemia and occasionally in ketoacidosis (DKA). The incidence of EIAS is increasing probably due to an overall increase in autoimmunity associated with the coronavirus disease 2019 (Covid-19) epidemic resulting in increasing binding of insulin by antibodies. Herein, we describe a case of EIAS occurring in an elderly patient with longstanding type 1 diabetes mellitus (T1DM) who had progressive loss of glycemic control. It responded positively, as we have previously described, to oral mycophenolate mofetil and the use of soluble regular insulin delivered by continuous subcutaneous insulin infusion (CSII). Therefore, EIAS is an increasingly frequent cause of hyperglycemia with and without DKA, and hypoglycemia in subjects with T1DM. Once diagnosed, they can be treated with mycophenolate mofetil and soluble insulin in an outpatient setting, which will decrease the rate of hospitalization and lower the expense of therapy.

The potential for improved outcomes in the prevention and therapy of diabetic kidney disease through 'stacking' of drugs from different classes.

Aggressive therapy of diabetic kidney disease (DKD) can not only slow the progression of DKD to renal failure but, if utilized at an early enough stage of DKD, can also stabilize and/or reverse the decline in renal function. The currently recognized standard of therapy for DKD is blockade of the renin-angiotensin system with angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs). However, unless utilized at a very early stage, monotherapy with these drugs in DKD will only prevent or slow the progression of DKD and will neither stabilize nor reverse the progression of DKD to renal decompensation. Recently, the addition of a sodium-glucose cotransporter-2 inhibitor and/or a mineralocorticoid receptor blocker to ACE inhibitors or ARBs has been clearly shown to further decelerate the decline in renal function. The use of glucagon-like peptide-1 (GLP-1) agonists shown promise in decelerating the progression of DKD. Other drugs that may aid in the deceleration the progression of DKD are dipeptidyl peptidase-4 inhibitors, pentoxifylline, statins, and vasodilating beta blockers. Therefore, aggressive therapy with combinations of these drugs (stacking) should improve the preservation of renal function in DKD.

In praise of pioglitazone: An economically efficacious therapy for type 2 diabetes and other manifestations of the metabolic syndrome.

Pioglitazone improves glycaemic control, not only by lowering insulin resistance, but also by improving beta cell function. Because of the improved beta cell function the glycaemic control that occurs with pioglitazone is prolonged. Pioglitazone has positive effects not only on cardiac risk factors and surrogate measures of cardiovascular disease, it also lowers the incidence of cardiac events in patients with diabetes. The recurrence of transient ischaemic attack and ischaemic stroke is also reduced in non-diabetic, insulin-resistant subjects. Utilized at preclinical stages (but not later) of heart failure, pioglitazone improves diastolic function and avoids progression to heart failure. Pioglitazone, through suppression of atrial remodelling, also decreases the incidence of atrial fibrillation. The manifestations of diseases associated with insulin resistance (non-alcoholic steatohepatitis and polycystic ovary disease) are also improved with pioglitazone. Pioglitazone may possibly improve psoriasis and other dermopathies. Pioglitazone is therefore an inexpensive and efficacious drug for the insulin-resistant subject with diabetes that is underutilized because of biases that have evolved from the toxicities of other thiazolidinediones.

Management of the 'wicked' combination of heart failure and chronic kidney disease in the patient with diabetes.

Patients with type 2 diabetes are at an increased risk of developing heart failure and chronic kidney disease. The presence of these co-morbidities substantially increases the risk of morbidity as well as mortality in patients with diabetes. The clinical focus has historically centred around reducing the risk of cardiovascular disease by targeting hyperglycaemia, hyperlipidaemia and hypertension. Nonetheless, patients with type 2 diabetes who have well-controlled blood glucose, blood pressure and lipid levels may still go on to develop heart failure, kidney disease or both. Major diabetes and cardiovascular societies are now recommending the use of treatments such as sodium-glucose co-transporter-2 inhibitors and non-steroidal mineralocorticoid receptor antagonists, in addition to currently recommended therapies, to promote cardiorenal protection through alternative pathways as early as possible in individuals with diabetes and cardiorenal manifestations. This review examines the most recent recommendations for managing the risk of cardiorenal progression in patients with type 2 diabetes.

Heart failure and diabetes: Clinical significance and epidemiology of this two-way association.

People with type 2 diabetes (T2DM) and those with prediabetes have an increased risk of heart failure (HF). Longer duration of T2DM correlates with a greater risk of HF, but HF is also seen in patients with recent-onset diabetes. Insulin resistance is more likely to be present in patients with HF. The risk of HF persists even in the face of standard-of-care preventive treatments for atherosclerotic cardiovascular (CV) disease. HF is commonly the presenting symptom of CV disease in people with diabetes and is the most expensive complication of diabetes because of the high cost of hospitalizations. Recently hospitalization for HF has been included in CV outcome trials (CVOTs), including for medications that are used to treat T2DM, which has led to new therapies for all HF patients. In addition, these CVOTs have shown that many drugs used in the therapy of diabetes are either neutral or detrimental in the HF patient and should be used with caution in patients with existing HF or those at high risk of HF. Most recently, sodium-glucose cotransporter-2 receptor blockers have shown efficacy in both HF with reduced ejection fraction (EF) and HF with preserved EF. The only other oral or injectable diabetes agent shown to improve outcomes in both is metformin.

Testosterone Deficiency is Not Protective Against the Development of Adenocarcinoma of the Prostate in a Type 1 Diabetic Patient.

We present a case of prostate cancer (PC) developing in a hypogonadal patient with well-controlled type 1 diabetes. The purpose of reporting this case is to emphasize that regular prostate examinations and prostate-specific antigen (PSA) measurements should be preformed in the diabetic male, even though the incidence of PC is lower in this group of patients. In addition, these examinations and tests need to be preformed even in the hypogonadal patient with diabetes since the presence of a low serum testosterone (T) level does not preclude the development of PC. This is because the development of PC is not related to serum androgen levels but to the androgen levels within the prostate, and dihydrotestosterone (DHT) levels and not T levels within the prostate gland are responsible for the development of PC. In the hypogonadal male, intraprostatic DHT may be high since DHT can be formed from adrenal androgens, particularly androstenedione, through activation of 5α-reductase 2, which is the minority enzyme in the normal prostate but becomes the major enzyme in the formation and growth of PC.

Development of Exogenous Insulin Antibody Syndrome in a Patient with Newly Diagnosed Type 1 Diabetes Successfully Treated with Oral Immunosuppressive Monotherapy.

Exogenous insulin antibody syndrome (EIAS), which rarely occurs in the patient with type 1 diabetes, results in antibody-induced insulin resistance, hyperglycemia, ketosis, ketoacidosis, and hypoglycemia when insulin is released from the saturated insulin antibodies. Recommended treatment regimens include glucocorticoids, immunosuppressants, and plasmapheresis. In the patient with type 1 diabetes, glucocorticoids may by inducing and/or worsening ketoacidosis be contraindicated. With immunosuppressants, various anecdotal treatment regimens have been reported. Currently the most commonly recommended regimen is intravenous immunosuppressive therapy in combination with oral immunosuppressants. Herein we describe a patient in whom oral immunosuppressant monotherapy with mycophenolate resulted in the cure of EIAS, thus avoiding the expense associated with intravenous immunosuppressant therapy and/or hospitalization for plasmapheresis.

Successful debulking of plurihormonal pituitary macroadenoma with long-acting pasireotide and dopamine agonist combination therapy.

Long-acting pasireotide and bromocriptine provided biochemical control of growth hormone and prolactin in a patient with plurihormonal pituitary macroadenoma, allowing near-complete tumor excision while restoring pituitary function and avoiding adjunctive radiotherapy. Pasireotide initiation resulted in hyperglycemia, which stabilized after a few months and resolved upon pasireotide discontinuation (ACCESS; NCT01995734).

Management of type 2 diabetes: evolving strategies for the treatment of patients with type 2 diabetes.

The prevalence of type 2 diabetes continues to increase at an alarming rate around the world, with even more people being affected by prediabetes. Although the pathogenesis and long-term complications of type 2 diabetes are fairly well known, its treatment has remained challenging, with only half of the patients achieving the recommended hemoglobin A(1c) target. This narrative review explores the pathogenetic rationale for the treatment of type 2 diabetes, with the view of fostering better understanding of the evolving treatment modalities. The diagnostic criteria including the role of hemoglobin A(1c) in the diagnosis of diabetes are discussed. Due attention is given to the different therapeutic maneuvers and their utility in the management of the diabetic patient. The evidence supporting the role of exercise, medical nutrition therapy, glucose monitoring, and antiobesity measures including pharmacotherapy and bariatric surgery is discussed. The controversial subject of optimum glycemic control in hospitalized and ambulatory patients is discussed in detail. An update of the available pharmacologic options for the management of type 2 diabetes is provided with particular emphasis on newer and emerging modalities. Special attention has been given to the initiation of insulin therapy in patients with type 2 diabetes, with explanation of the pathophysiologic basis for insulin therapy in the ambulatory diabetic patient. A review of the evidence supporting the efficacy of the different preventive measures is also provided.
