Summary
Diabetic foot ulcer morbidity and mortality are dramatically increasing worldwide, reinforcing the urgency to propose more effective interventions to treat such a devastating condition. Previously, using a diabetic mouse model, we demonstrated that administration of bone marrow mesenchymal stem cells derivatives is more effective than the use of bone marrow mesenchymal stem cells alone. Here, we used the aforementioned treatments on three patients with grade 2 diabetic foot ulcers and assessed their beneficial effects, relative to the conventional approach. In the present study, two doses of cell derivatives, one dose of mesenchymal stem cells or one dose of vehicle (saline solution with 5% of human albumin), were intradermally injected around wounds. Wound healing process and changes on re-epithelialization were macroscopically evaluated until complete closure of the ulcers. All ulcers were simultaneously treated with conventional treatment (PolyMen® dressing). Patients treated with either cell derivatives or mesenchymal stem cells achieved higher percentages of wound closure in shorter times, relative to the patient treated with the conventional treatment. The cell derivative and mesenchymal stem cells approaches resulted in complete wound closure and enhanced skin regeneration at some point between days 35 and 42, although no differences between these two treatments were observed. Moreover, wounds treated with the conventional treatment healed after 161 days. Intradermal administration of cell derivatives improved wound healing to a similar extent as mesenchymal stem cells. Thus, our results suggest that mesenchymal stem cell derivatives may serve as a novel and potential therapeutic approach to treat diabetic foot ulcers.
Learning points:
-
In diabetic mouse models, the administration of mesenchymal stem cells derivatives have been demonstrated to be more effective than the use of marrow mesenchymal stem cells alone.
-
Mesenchymal stem cells have been explored as an attractive therapeutic option to treat non-healing ulcers.
-
Mesenchymal stem cells derivatives accelerate the re-epithelialization on diabetic foot ulcers.

Summary
Pituitary infections, particularly with fungus, are rare disorders that usually occur in immunocompromised patients. Cushing’s syndrome predisposes patients to infectious diseases due to their immunosuppression status. We report the case of a 55-year-old woman, working as a poultry farmer, who developed intense headache, palpebral ptosis, anisocoria, prostration and psychomotor agitation 9 months after initial diabetes mellitus diagnosis. Cranioencephalic CT scan showed a pituitary lesion with bleeding, suggesting pituitary apoplexy. Patient underwent transsphenoidal surgery and the neuropathologic study indicated a corticotroph adenoma with apoplexy and fungal infection. Patient had no preoperative Cushing’s syndrome diagnosis. She was evaluated by a multidisciplinary team who decided not to administer anti-fungal treatment. The reported case shows a rare association between a corticotroph adenoma and a pituitary fungal infection. The possible contributing factors were hypercortisolism, uncontrolled diabetes and professional activity. Transsphenoidal surgery is advocated in these infections; however, anti-fungal therapy is still controversial.
Learning points:
-
Pituitary infections are rare disorders caused by bacterial, viral, fungal and parasitic infections.
-
Pituitary fungal infections usually occur in immunocompromised patients.
-
Cushing’s syndrome, as immunosuppression factor, predisposes patients to infectious diseases, including fungal infections.
-
Diagnosis of pituitary fungal infection is often achieved during histopathological investigation.
-
Treatment with systemic anti-fungal drugs is controversial.
-
Endocrine evaluation is recommended at the time of initial presentation of pituitary manifestations.

Summary
Mifepristone is a promising option for the management of hypercortisolism associated with hyperglycemia. However, its use may result in serious electrolyte imbalances, especially during dose escalation. In our patient with adrenocorticotropic hormone-independent macro-nodular adrenal hyperplasia, unilateral adrenalectomy resulted in biochemical and clinical improvement, but subclinical hypercortisolism persisted following adrenalectomy. She was started on mifepristone. Unfortunately, she missed her follow-up appointments following dosage escalation and required hospitalization at an intensive care level for severe refractory hypokalemia.

Summary
A 45-year-old man with poorly controlled type 2 diabetes (T2DM) (HbA1c 87 mmol/mol) despite 100 units of insulin per day and severe obesity (BMI 40.2 kg/m2) was referred for bariatric intervention. He declined bariatric surgery or GLP1 agonist therapy. Initially, his glycaemic control improved with dietary modification and better adherence to insulin therapy, but he gained weight. We started a low-energy liquid diet, with 2.2 L of semi-skimmed milk (equivalent to 1012 kcal) per day for 8 weeks (along with micronutrient, salt and fibre supplementation) followed by 16 weeks of phased reintroduction of a normal diet. His insulin was stopped within a week of starting this programme, and over 6 months, he lost 20.6 kg and his HbA1c normalised. However, 1 year later, despite further weight loss, his HbA1c deteriorated dramatically, requiring introduction of linagliptin and canagliflozin, with good response. Five years after initial presentation, his BMI remains elevated but improved at 35.5 kg/m2 and his glycaemic control is excellent with a HbA1c of 50 mmol/mol and he is off insulin therapy. Whether semi-skimmed milk is a safe, effective substrate for carefully selected patients with severe obesity complicated by T2DM remains to be determined. Such patients would need frequent monitoring by an experienced multidisciplinary team.
Learning points:
-
Meal replacement programmes are an emerging therapeutic strategy to allow severely obese type 2 diabetes patients to achieve clinically impactful weight loss.
-
Using semi-skimmed milk as a meal replacement substrate might be less costly than commercially available programmes, but is likely to require intensive multidisciplinary bariatric clinical follow-up.
-
For severely obese adults with poor diabetes control who decline bariatric surgery or GLP1 agonist therapy, a milk-based meal replacement programme may be an option.
-
Milk-based meal replacement in patients with insulin requiring type 2 diabetes causes rapid and profound reductions in insulin requirements, so rigorous monitoring of glucose levels by patients and their clinicians is necessary.
-
In carefully selected and adequately monitored patients, the response to oral antidiabetic medications may help to differentiate between absolute and relative insulin deficiency.

Summary
A 28-year-old male presented with 2 days of vomiting and abdominal pain, preceded by 2 weeks of thirst, polyuria and polydipsia. He had recently started risperidone for obsessive-compulsive disorder. He reported a high dietary sugar intake and had a strong family history of type 2 diabetes mellitus (T2DM). On admission, he was tachycardic, tachypnoeic and drowsy with a Glasgow Coma Scale (GCS) of 10/15. We noted axillary acanthosis nigricans and obesity (BMI 33.2 kg/m2). Dipstick urinalysis showed ketonuria and glycosuria. Blood results were consistent with diabetic ketoacidosis (DKA), with hyperosmolar state. We initiated our DKA protocol, with intravenous insulin, fluids and potassium, and we discontinued risperidone. His obesity, family history of T2DM, acanthosis nigricans and hyperosmolar state prompted consideration of T2DM presenting with ‘ketosis-prone diabetes’ (KPD) rather than T1DM. Antibody markers of beta-cell autoimmunity were subsequently negative. Four weeks later, he had modified his diet and lost weight, and his metabolic parameters had normalised. We reduced his total daily insulin dose from 35 to 18 units and introduced metformin. We stopped insulin completely by week 7. At 6 months, his glucometer readings and glycated haemoglobin (HbA1c) level had normalised.
Learning points:
-
Risperidone-induced diabetic ketoacidosis (DKA) is not synonymous with type 1 diabetes, even in young white patients and may be a manifestation of ‘ketosis-prone’ type 2 diabetes (KPD).
-
KPD is often only confirmed after the initial presentation, when islet autoimmunity and cautious phasing out of insulin therapy have been assessed, and emergency DKA management remains the same.
-
As in other cases of KPD, a family history of T2DM and presence of cutaneous markers of insulin resistance were important clinical features suggestive of an alternative aetiology for DKA.

Summary
Myotonic dystrophy type 1 (DM1) is an autosomal dominant multisystem disease affecting muscles, the eyes and the endocrine organs. Diabetes mellitus and primary hypogonadism are endocrine manifestations typically seen in patients with DM1. Abnormalities of hypothalamic–pituitary–adrenal (HPA) axis have also been reported in some DM1 patients. We present a case of DM1 with a rare combination of multiple endocrinopathies; diabetes mellitus, a combined form of primary and secondary hypogonadism, and dysfunction of the HPA axis. In the present case, diabetes mellitus was characterized by severe insulin resistance with hyperinsulinemia. Glycemic control improved after modification of insulin sensitizers, such as metformin and pioglitazone. Hypogonadism was treated with testosterone replacement therapy. Notably, body composition analysis revealed increase in muscle mass and decrease in fat mass in our patient. This implies that manifestations of hypogonadism could be hidden by symptoms of myotonic dystrophy. Our patient had no symptoms associated with adrenal deficiency, so adrenal dysfunction was carefully followed up without hydrocortisone replacement therapy. In this report, we highlight the necessity for evaluation and treatment of multiple endocrinopathies in patients with DM1.
Learning points:
-
DM1 patients could be affected by a variety of multiple endocrinopathies.
-
Our patients with DM1 presented rare combinations of multiple endocrinopathies; diabetes mellitus, combined form of primary and secondary hypogonadism and dysfunction of HPA axis.
-
Testosterone treatment of hypogonadism in patients with DM1 could improve body composition.
-
The patients with DM1 should be assessed endocrine functions and treated depending on the degree of each endocrine dysfunction.
