Somatostatin analogs are an invaluable therapeutic option in the diagnosis and treatment of somatotropinomas, thyrotropinomas, and functioning and non-functioning gastroenteropancreatic neuroendocrine tumors. They should also be considered an effective and safe therapeutic alternative to corticotropinomas, gonadotropinomas, and prolactinomas resistant to dopamine agonists. Somatostatin analogs have also shown to be useful in the treatment of other endocrine diseases (congenital hyperinsulinism, Graves’ orbitopathy, diabetic retinopathy, diabetic macular edema), non-endocrine tumors (breast, colon, prostate, lung, and hepatocellular), and digestive diseases (chronic refractory diarrhea, hepatorenal polycystosis, gastrointestinal hemorrhage, dumping syndrome, and intestinal fistula).

Background and Objectives: Differentiating between hypovolemic (HH) and euvolemic hyponatremia (EH) is crucial for correct diagnosis and therapy, but can be a challenge. We aim to ascertain whether changes in serum creatinine (SC) can be helpful in distinguishing HH from EH. Materials and Methods: Retrospective analysis of patients followed in a monographic hyponatremia outpatient clinic of a tertiary hospital during 1 January 2014–30 November 2019. SC changes during HH and EH from eunatremia were studied. The diagnostic accuracy of the SC change from eunatremia to hyponatremia (∆SC) was analyzed. Results: A total of 122 hyponatremic patients, median age 79 years (70–85), 46.7% women. In total, 70/122 patients had EH, 52/122 HH. During hyponatremia, median SC levels increased in the HH group: +0.18 mg/dL [0.09–0.39, p < 0.001], but decreased in the EH group: −0.07 mg/dL (−0.15–0.02, p < 0.001), as compared to SC in eunatremia. HH subjects presented a higher rate of a positive ∆SC than EH (90.4% vs. 25.7%, p < 0.001). EH subjects presented a higher rate of a negative/null ∆SC than HH (74.3% vs. 9.6%, p < 0.001). ROC curve analysis found an AUC of 0.908 (95%CI: 0.853 to 0.962, p < 0.001) for ∆SC%. A ∆SC% ≥ 10% had an OR of 29.0 (95%CI: 10.3 to 81.7, p < 0.001) for HH. A ∆SC% ≤ 3% had an OR of 68.3 (95%CI: 13.0 to 262.2, p < 0.001) for EH. Conclusions: The assessment of SC changes from eunatremia to hyponatremia can be useful in distinguishing between HH and EH.

Aim: This study aimed to evaluate the effectiveness and tolerability of intensifying the dose of canagliflozin from 100 mg/day (CANA100) to 300 mg/day (CANA300) in patients with type 2 diabetes (T2DM) and suboptimal metabolic control in a real-world setting. Methods: A multicenter observational study was conducted on adult patients with T2DM who initiated treatment with CANA100 and subsequently required intensification to CANA300. The primary outcome measures were changes in HbA1c and weight at 6 months after the switch and at the end of the follow-up period. Results: A total of 317 patients met the inclusion criteria (59.6% male, mean age 62.2 years, baseline HbA1c 7.55%, weight 88.6 kg, median duration of treatment with CANA100 9.9 months). Switching to CANA300 resulted in a significant reduction in HbA1c (6 months: −0.33%; last visit: −0.47%, both p < 0.0001) and weight (6 months: −1.8 kg; last visit: −2.9 kg, both p < 0.0001) over a median follow-up period of 20.8 months. The proportion of patients that achieved HbA1c < 7% increased from 26.7% with CANA100 to 51.6% with CANA300 (p < 0.0001). Among individuals with poor baseline glycemic control (HbA1c > 8%, mean 9.0%), HbA1c was significantly reduced by −1.24% (p < 0.0001). Furthermore, significant improvements were observed in fasting plasma glucose (FPG), blood pressure (BP), liver enzymes, and albuminuria. No unexpected adverse events were reported. Conclusions: Intensifying the treatment to CANA300 in a real-world setting resulted in further significant and clinically relevant reductions in FPG, HbA1c, weight, and BP in patients with T2DM. The switch was particularly effective in patients with higher baseline HbA1c levels.

Scalp hair loss is an underreported adverse event of somatostatin analogs therapy that in severe cases may require treatment withdrawal. It can be related to an acute decrease in GH/IGF-1 levels, but a direct effect cannot be ruled out.

Background: Subcutaneous semaglutide has shown kidney-protective effects in people with type 2 diabetes (PWT2D), but data on oral semaglutide remain limited. This multicenter real-world study evaluates the clinical effectiveness of oral semaglutide on kidney outcomes in PWT2D. Methods: We included PW2TD aged ≥18 years who initiated oral semaglutide in routine practice between 2021 and 2022 in the Spanish National Health System, with at least one report of clinical follow-up (FU) data at 3 months. Co-primary endpoints were changes in urinary albumin to creatinine ratio (UACR) and estimated glomerular filtration rate (eGFR) slope at 6-12 months. We also assessed baseline predictors of response, drug persistence, and safety by CKD severity. Results: Data were available for 819 PWT2D (median age 63 years, eGFR 88.1mL/min/1.73m2, UACR 12 mg/g, 45.8% female), median FU was 8.96 months. Oral semaglutide reduced UACR by 30.3% and 40.0% in the overall cohort, by 40.2% and 50.7% in those with a UACR ≥ 30 mg/g, and by 40.6% and 49.9% in those with a UACR ≥ 300 mg/g at 6 and 12-months FU, respectively. PWT2D with a low age-adjusted risk of liver fibrosis by the FIB-4 index had increased odds of achieving a >30% reduction in UACR (aOR 5.50 [95%CI 1.6-18.7]) regardless of baseline background. Metabolic and weight loss effectiveness, safety and persistence of oral semaglutide were consistent across CKD severities. Conclusions: In a real-world setting, oral semaglutide treatment for up to 52 weeks resulted in clinically meaningful reductions in albuminuria without changes in eGFR slope in PWT2D. Effectiveness, safety and tolerability were not influenced by CKD severity.
