Summary

There is a close association between obesity and type 2 diabetes (T2D). The value of weight loss in the management of patients with T2D has long been known. Loss of 15% or more of body weight can have a disease-modifying effect in people with diabetes inducing remission in a large proportion of patients. Very low-carbohydrate ketogenic diets (VLCKDs) have been proposed as an appealing nutritional strategy for obesity management. The diet was shown to result in significant weight loss in the short, intermediate, and long terms and improvement in body composition parameters as well as glycemic and lipid profiles. The reported case is a 35-year-old man with obesity, dyslipidemia, and T2D for 5 years. Despite the use of five antidiabetic medications, including insulin, HbA1c was 10.1%. A VLCKD through a commercial multidisciplinary weight loss program (PnK method) was prescribed and all medications were discontinued. The method is based on high-biological-value protein preparations and has 5 steps, the first 3 steps (active stage) consist of a VLCKD (600–800 kcal/d) that is low in carbohydrates (<50 g daily from vegetables) and lipids. The amount of proteins ranged between 0.8 and 1.2 g/kg of ideal body weight. After only 3 months, the patient lost 20 kg with weight normalization and diabetes remission, and after 2 years of follow-up, the patient remained without the pathologies. Due to the rapid and significant weight loss, VLCKD emerges as a useful tool in T2D remission in patients with obesity.

Learning points

  • Obesity and type 2 diabetes (T2D) are conditions that share key pathophysiological mechanisms.

  • Loss of 15% or more of body weight can have a disease-modifying effect in people with T2D inducing remission in a large proportion of patients.

  • Diabetes remission should be defined as a return of HbA1c to <6.5% and which persists for at least 3 months in the absence of usual glucose-lowering pharmacotherapy.

  • The very low-carbohydrate ketogenic diet (VLCKD) is a nutritional approach that has significant beneficial effects on anthropometric and metabolic parameters.

  • Due to the rapid and significant weight loss, VLCKD emerges as a useful tool in T2D remission in patients with obesity.

Summary

Drinking fruit juice is an increasingly popular health trend, as it is widely perceived as a source of vitamins and nutrients. However, high fructose load in fruit beverages can have harmful metabolic effects. When consumed in high amounts, fructose is linked with hypertriglyceridemia, fatty liver and insulin resistance. We present an unusual case of a patient with severe asymptomatic hypertriglyceridemia (triglycerides of 9182 mg/dL) and newly diagnosed type 2 diabetes mellitus, who reported a daily intake of 15 L of fruit juice over several weeks before presentation. The patient was referred to our emergency department with blood glucose of 527 mg/dL and glycated hemoglobin (HbA1c) of 17.3%. Interestingly, features of diabetic ketoacidosis or hyperosmolar hyperglycemic state were absent. The patient was overweight with an otherwise unremarkable physical exam. Lipase levels, liver function tests and inflammatory markers were closely monitored and remained unremarkable. The initial therapeutic approach included i.v. volume resuscitation, insulin and heparin. Additionally, plasmapheresis was performed to prevent potentially fatal complications of hypertriglyceridemia. The patient was counseled on balanced nutrition and detrimental effects of fruit beverages. He was discharged home 6 days after admission. At a 2-week follow-up visit, his triglyceride level was 419 mg/dL, total cholesterol was 221 mg/dL and HbA1c was 12.7%. The present case highlights the role of fructose overconsumption as a contributory factor for severe hypertriglyceridemia in a patient with newly diagnosed diabetes. We discuss metabolic effects of uncontrolled fructose ingestion, as well as the interplay of primary and secondary factors, in the pathogenesis of hypertriglyceridemia accompanied by diabetes.

Learning points

  • Excessive dietary fructose intake can exacerbate hypertriglyceridemia in patients with underlying type 2 diabetes mellitus (T2DM) and absence of diabetic ketoacidosis or hyperosmolar hyperglycemic state.

  • When consumed in large amounts, fructose is considered a highly lipogenic nutrient linked with postprandial hypertriglyceridemia and de novo hepatic lipogenesis (DNL).

  • Severe lipemia (triglyceride plasma level > 9000 mg/dL) could be asymptomatic and not necessarily complicated by acute pancreatitis, although lipase levels should be closely monitored.

  • Plasmapheresis is an effective adjunct treatment option for rapid lowering of high serum lipids, which is paramount to prevent acute complications of severe hypertriglyceridemia.

Summary

Ten years after the successful withdrawal from heroin abuse, a person with diabetes suffered intractable pain and severe muscular emaciation consistent with the syndrome of diabetic neuropathic cachexia. Anti-neuropathic medications failed neither to alleviate suffering and reverse weight loss, nor to stop muscular emaciation. Vigilant evaluation for weight loss aetiologies revealed no responsible aetiology. Prescribing medical cannabis became mandatory, with the intention to alleviate neuropathic pain, regain muscular mass and strengthen legs, enable standing upright and walking normally. Medical cannabis for pain-relief, and the orexigenic properties of tetrahydrocannabinol (THC) ingredient successfully achieved these goals.

Learning points:

  • Medical cannabis can serve to promptly alleviate severe diabetic neuropathic pain.

  • Past history of heroin abuse was not an absolute contraindication to medical cannabis use.

  • Medical cannabis increased appetite and reversed muscular emaciation.

  • Medical cannabis decreased chronic pain and hence, its catabolic consequences.

Summary

Madelung's disease is a rare fat metabolism disorder characterised by benign multiple symmetric, encapsulated lipomatosis. The exact cause of the disease is unknown; it may be associated with chronic alcoholism and mutations in mitochondrial DNA (A8344G), but there have been cases without these factors reported in the literature. A 29-year-old man with a 6-year history of diabetes mellitus was admitted to our hospital for poorly regulated diabetes and decreased libido. He was not an alcohol consumer. His family history was unremarkable. Physical examination revealed that he had a eunuchoid body shape. There was a symmetric excess fat accumulation in his submandibular, deltoid, nuchal, suprapubic and inguinal areas. He was diagnosed with Madelung's disease, and imaging studies supported the diagnosis. Hormonal evaluation revealed a hypergonadotropic hypogonadism. Karyotype analysis revealed a 47,XXY mutation. Genetic research showed no mitochondrial DNA mutation. Metabolic disorders, such as diabetes mellitus, hyperlipidaemia, hyperuricaemia and liver disease, endocrine gland diseases, such as hypothyroidism, and neurological diseases, such as polyneuropathy and cognitive disorders, may accompany Madelung's disease. The present study represents the first reported case of Madelung's disease accompanied by Klinefelter's syndrome.
