Semaglutide Treatment in Adult-Onset Autoimmune Diabetes: A Case Study With Long-Term Follow-Up and Periodic Evaluation of Beta-Cell Function.

Latent autoimmune diabetes of adults (LADA) is a form of autoimmune diabetes that typically occurs in adulthood and has intermediate characteristics between type 1 and type 2 diabetes. To optimize the diagnostic and therapeutic approach, recently, a subclassification of LADA has been proposed based on some clinical features, antibodies, and beta cellular function at onset. In this paper, we expose an interesting case showing the effectiveness of early treatment with a glucagon-like peptide receptor agonist (semaglutide) in maintaining long-term good glycemic control and associated with the preservation of beta-cell function over a five-year observation period in a young woman with LADA.

The impact of body composition on mortality of COVID-19 hospitalized patients: A prospective study on abdominal fat, obesity paradox and sarcopenia.

BACKGROUND & AIMS: Obesity has been described as a predisposing risk factor to severe forms of COVID-19, but conflicting results are emerging on its real impact on the mortality of COVID-19. We aimed to compare clinical outcomes and mortality among COVID-19 patients according to obesity, metabolic syndrome and adiposity distribution. METHODS: We conducted a prospective observational study of all consecutive adult patients with a confirmed diagnosis of SARS-CoV-2 infection admitted to the Infectious Diseases Clinic at Udine Hospital, Italy, from January 2021 to February 2021. At admission, the study population was submitted to specific anthropometric, laboratory and bioimpedance analysis (BIA) measurements and divided into five groups according to: 1) BMI < or >30 kg/m2; 2) waist circumference (WC) < or >98 cm for women, < or >102 cm for men; 3) presence or absence of metabolic syndrome (MS); 4) visceral adipose tissue (VAT) distribution; and 5) presence or absence of sarcopenia (SP) both based on BIA. We then compared clinical outcomes (ventilatory support, intensive care unit (ICU) admission, ICU length of stay, total hospital length of stay and mortality), immune and inflammatory makers and infectious and non-infectious acute complications within the five groups. RESULTS: A total of 195 patients were enrolled in the study. The mean age of patients was 71 years (IQR 61-80) and 64.6% (126) were male. The most common comorbidities were hypertension (55.9%) and MS (55.4%). Overall mortality was 19.5%. Abdominal adiposity, measured both with WC and with BIA, and SP were significantly associated with need for increased ventilator support (p = 0.013 for WC; p = 0.037, 0.027 and 0.009 for VAT; p = 0.004 and 0.036 for FMI; and p = 0.051 for SP), but not with ICU admission (WC p = 0.627, VAT p = 0.153, FMI p = 0.519 and SP p = 0.938), length of stay (WC p = 0.345, VAT p = 0.650, FMI p = 0.159 and SP p = 0.992) and mortality (WC p = 0.277, VAT p = 0.533, FMI p = 0.957 and SP p = 0.211). Obesity and MS did not discriminate for the intensity of ventilatory outcome (p = 0.142 and p = 0.198, respectively), ICU admission (p = 0.802 and p = 0.947, respectively), length of stay (p = 0.471 and p = 0.768, respectively) and mortality (p = 0.495 and p = 0.268, respectively). We did not find significant differences in inflammatory markers and secondary complications within the five groups. CONCLUSIONS: In patients admitted with COVID-19, increased WC, visceral abdominal fat and SP are associated with higher need for ventilatory support. However, obesity, MS, SP and abdominal adiposity are not sensitive predictive factors for mortality.

Prognostic Role of Malnutrition Diagnosed by Bioelectrical Impedance Vector Analysis in Older Adults Hospitalized with COVID-19 Pneumonia: A Prospective Study.

BACKGROUND: Little is known on the clinical relevance of the nutritional status and body composition of patients hospitalized with SARS-CoV-2 infection. The aim of our study was to assess the prevalence of malnutrition in patients with COVID-19 pneumonia using bioelectrical impedance vector analysis (BIVA), and to evaluate the relationship of their nutritional status with the severity and outcome of disease. METHODS: Among 150 consecutive patients who were hospitalized with COVID-19 pneumonia, 37 (24.3%) were classified as malnourished by BIVA, and were followed-up for 60 days from admission. Outcome measures were differences in the need for invasive mechanical ventilation, in-hospital mortality, and the duration of hospital stay in survivors. RESULTS: During 60 days of follow-up, 10 (27%) malnourished patients and 13 (12%) non-malnourished patients required invasive mechanical ventilation (p = 0.023), and 13 (35%) malnourished patients and 9 (8%) non-malnourished patients died (p < 0.001). The average duration of the hospital stay in survivors was longer in patients with malnutrition (18.2 ± 15.7 vs. 13.2 ± 14.8 days, p < 0.001). In survival analyses, mechanical ventilation free (log-rank 7.887, p = 0.050) and overall (log-rank 17.886, p < 0.001) survival were significantly longer in non-malnourished than malnourished patients. The Cox proportional ratio showed that malnutrition was associated with an increased risk of mechanical ventilation (HR 4.375, p = 0.004) and death (HR 4.478, p = 0.004) after adjusting for major confounders such as age, sex, and BMI. CONCLUSIONS: Malnutrition diagnosed with BIVA was associated with worse outcomes in hospitalized patients with COVID-19 pneumonia.

Polyphenols Rich Diets and Risk of Type 2 Diabetes.

Type 2 diabetes is an increasing health concern worldwide. Both genetic and environmental risk factors as improper dietary habits or physical inactivity are known to be crucial in the pathogenesis of type 2 diabetes. Polyphenols are a group of plant-derived compounds with anti-inflammatory and antioxidant properties that are associated with a low prevalence of metabolic conditions characterized by insulin resistance, including obesity, diabetes, and hypertension. Moreover, there is now full awareness that foods that are rich in phytochemicals and polyphenols could play an important role in preserving human cardiovascular health and substantial clinical evidence indicates that regular dietary consumption of such foods affects favorably carbohydrate metabolism. This review briefly summarizes the evidence relating dietary patterns rich in polyphenols with glucose metabolism and highlights the potential benefits of these compounds in the prevention of type 2 diabetes.

Beware of Drug Interactions Treating Iatrogenic Mycobacterium bovis Endocarditis from Intravesical BCG Instillation.

We report a case of mechanical mitral valve endocarditis associated with miliary disseminated bacillus Calmette-Guerin (BCG) infection following intravesical instillations for minimally invasive bladder cancer in a 65-year-old man. The diagnosis was established by echocardiographic evidence of vegetation on the prosthetic mitral valve, miliary lesions in the lungs and evidence of bloodstream infection sustained by Mycobacterium. We successfully treated the patient with the classical regimen of quadruple antituberculous therapy. LEARNING POINTS: To consider endocarditis as an extra-pulmonary manifestation of Mycobacterium bovis infection, especially in the presence of predisposing heart conditions and risk factors.To be careful of drug interactions among warfarin, rifampin and amiodarone.

The Pivotal Role of Oleuropein in the Anti-Diabetic Action of the Mediterranean Diet: A Concise Review.

Type 2 diabetes currently accounts for more than 90% of all diabetic patients. Lifestyle interventions and notably dietary modifications are one of the mainstays for the prevention and treatment of type 2 diabetes. In this context, the Mediterranean diet with its elevated content of phytonutrients has been demonstrated to effectively improve glucose homeostasis. Oleuropein is the most abundant polyphenolic compound contained in extra-virgin olive oil and might account for some of the anti-diabetic actions of the Mediterranean diet. With the aim to provide an overview of the possible contributions of oleuropein to glucose metabolism, we conducted a PubMed/Medline search in order to provide an update to the available evidence regarding this interesting compound. This narrative review summarizes the data that was obtained in in vitro and animal studies and the results of clinical investigations. Preclinical studies indicate that oleuropein improves glucose transport, increases insulin sensitivity, and facilitates insulin secretion by pancreatic ß-cells, thereby supporting the hypothesis of the possible benefits of the control of hyperglycemia. However, on the clinical side, the available evidence is still preliminary and requires more extensive investigations. Thus, many questions remain unanswered in regards to the potential benefits of oleuropein in diabetes prevention and treatment. These questions should be addressed in appropriately designed studies in the future.

Dulaglutide reduces binge episodes in type 2 diabetic patients with binge eating disorder: A pilot study.

AIMS: Binge eating disorder (BED) is the most common eating disorder in the United States and Europe and is associated with obesity and type 2 diabetes (T2D). Presence and severity of BED have been associated with worse metabolic control and greater BMI in T2D patients. Glucagon Like Peptide-1 (GLP1) receptors are present in central nervous system areas involved in appetite regulation and treatment with GLP-1 receptor agonists modulates appetite and reward-related brain areas in humans. We evaluated the effects of treatment with dulaglutide on eating behavior in T2D outpatients with BED. METHODS: This was a pilot open label, prospective controlled study. Inclusion criteria were: Age ≤65, HbA1c between 7.5 and 9% on metformin therapy alone, normal renal function and diagnosis of BED. Patients were randomly assigned to receive either Dulaglutide 1,5 mg/sett or Gliclazide 60 mg for 12 weeks. We evaluated baseline binge eating scale score (BES), weight, BMI, percentage fat mass, HbA1c and their changes after treatment. A multivariate linear regression model was used to verify the association between Δ BES from baseline with Δ Hba1c and variation of anthropometric parameters after treatment. RESULTS: After 12 weeks patients treated with dulaglutide had grater reduction of binge eating behaviour (p < 0.0001), body weight (p < 0,0001), BMI (p < 0.0001), percentage fat mass (p < 0.0001) and HbA1c (p = 0.009) than patients treated with gliclazide. Reduction in BES was associated with reduction in body weight (p < 0.0001) and HbA1c (p = 0.033). CONCLUSION: Dulaglutide treatment reduces binge eating behaviour in T2D patients with BED.
