ABSTRACT
OBJECTIVE: To evaluate the association between acute-to-chronic (A/C) glycemic ratio and mortality and severity outcomes for patients with type 2 diabetes (T2D) hospitalized with coronavirus disease 2019 (COVID-19). RESEARCH DESIGN AND METHODS: A total of 91 patients were included. We measured glycemia at admission and estimated the average chronic glucose levels to calculate the A/C glycemic ratio. The primary outcome was a composite of in-hospital mortality, intensive care unit admission, and mechanical ventilation. RESULTS: Thirty-five patients had a primary outcome event, presenting a significant association with the A/C glycemic ratio (hazard ratio [HR] 1.57 [95% CI 1.14-2.15], P = 0.005). In comparisons with the 2nd tertile, the 3rd tertile of the A/C glycemic ratio was associated with the primary outcome (HR 3.39 [95% CI 1.31-8.75], P = 0.012). In the multivariate analysis, after additional adjustment for age, sex, comorbidities, inflammatory markers, and corticosteroid therapy, the association for the 3rd tertile (HR 3.96 [95% CI 1.35-11.59], P = 0.012) remained significant. CONCLUSIONS: In patients with T2D hospitalized with COVID-19, the imbalance between acute glycemia at admission and chronic metabolic control is associated with worse prognosis.

OBJECTIVE: Hyperglycemia may increase mortality in patients who receive total parenteral nutrition (TPN). However, this has not been well studied in noncritically ill patients (i.e., patients in the nonintensive care unit setting). The aim of this study was to determine whether mean blood glucose level during TPN infusion is associated with increased mortality in noncritically ill hospitalized patients. RESEARCH DESIGN AND METHODS: This prospective multicenter study involved 19 Spanish hospitals. Noncritically ill patients who were prescribed TPN were included prospectively, and data were collected on demographic, clinical, and laboratory variables as well as on in-hospital mortality. RESULTS: The study included 605 patients (mean age 63.2 ± 15.7 years). The daily mean TPN values were 1.630 ± 323 kcal, 3.2 ± 0.7 g carbohydrates/kg, 1.26 ± 0.3 g amino acids/kg, and 0.9 ± 0.2 g lipids/kg. Multiple logistic regression analysis showed that the patients who had mean blood glucose levels >180 mg/dL during the TPN infusion had a risk of mortality that was 5.6 times greater than those with mean blood glucose levels <140 mg/dL (95% CI 1.47-21.4 mg/dL) after adjusting for age, sex, nutritional state, presence of diabetes or hyperglycemia before starting TPN, diagnosis, prior comorbidity, carbohydrates infused, use of steroid therapy, SD of blood glucose level, insulin units supplied, infectious complications, albumin, C-reactive protein, and HbA1c levels. CONCLUSIONS: Hyperglycemia (mean blood glucose level >180 mg/dL) in noncritically ill patients who receive TPN is associated with a higher risk of in-hospital mortality.

The aim of the study was to evaluate the effects of the non-dihydropyridine calcium antagonist (NDCA) diltiazem on the development of urinary albumin excretion (UAE) in type 2 hypertensive diabetic patients with persistent microalbuminuria despite ACE inhibitor treatment. Thirty-six type 2 diabetic hypertensive patients with microalbuminuria persisting after at least 1 year of treatment with ACE inhibitors were randomized to receive captopril (n=22) or combined therapy with captopril and 120 mg diltiazem (n=14) for 2 years. Captopril dose was individualized according to blood pressure. Changes in UAE, blood pressure, and metabolic control were monitored to analyze the influence of the addition of diltiazem on progression of diabetic nephropathy. In patients treated with captopril and diltiazem, absolute UAE did not change during the study (baseline: 101 mg/24 h, range 39-298; 2 years after randomization: 74 mg/24 h, range 12-665). In contrast, UAE increased in patients treated with captopril monotherapy (baseline: 118 mg/24 h, range 32-282; 2 years after randomization: 164 mg/24 h, range 15-1161, p<0.05). In addition, fewer patients in the captopril/diltiazem group progressed to macroalbuminuria (eight patients in captopril group and one in captopril/diltiazem group, p<0.05). The beneficial effects of the addition of diltiazem were independent of blood pressure and metabolic control. We suggest that the combination of ACE inhibitors and NDCA should be considered in type 2 microalbuminuric patients at high risk for progression to established diabetic nephropathy.
