Steno type 1 risk engine and preclinical atherosclerosis in Mediterranean individuals with type 1 diabetes.

BACKGROUND AND AIMS: Tools to detect type 1 diabetes (T1D) individuals at overt cardiovascular disease (CVD) risk are scarce. We aimed to assess the usefulness of the score 'Steno Type 1 Risk Engine' (Steno-Risk) to identify T1D patients with advanced carotid atherosclerosis. MATERIAL AND METHODS: T1D patients without CVD with at least one of the following were included: ≥40 years, diabetic nephropathy, or diabetes duration ≥10 years with ≥1 CVD risk factor. Intima-media thickness (IMT) and plaque presence (IMT ≥1.5 mm) were assessed by standardized B-mode ultrasonography. Steno-Risk was used to estimate 10-year risk (<10% low; 10%-20% moderate; ≥20% high risk). Associations between Steno-Risk and preclinical atherosclerosis were assessed after adjusting for other CVD risk factors. RESULTS: We evaluated 302 patients (55% men, age 47.8 ± 9.8 years, T1D duration 26.3 ± 9.3 years). The prevalence of carotid plaque and ≥2 plaques were 36.4% and 19.2%, respectively; without sex differences. Age (57.4 ± 7.4 vs 37.1 ± 6.2 years), T1D duration (31.3 ± 10.4 vs 21.5 ± 7.1 years), hypertension (52.3% vs 6.3%), nephropathy (25.6% vs 5.1%) and retinopathy (53.5% vs 32.9%) were higher in high-risk (n = 86) vs low-risk participants (n = 79; P < .001 for all). Preclinical atherosclerosis (IMT and plaque) increased in parallel with Steno-Risk (P < .001). In logistic regression analysis, both age ≥40 years and Steno-Risk ≥20% were associated with the presence of plaque (OR 4.22 [1.57-11.36] and 3.79 [1.61-6.80]; respectively), but only high Steno-Risk remained independently associated with ≥2 plaques (OR 3.31 [1.61-6.80]). CONCLUSION: Steno-Risk is independently associated with preclinical atherosclerosis. Further studies are needed to ascertain its usefulness in this high-risk population.

Clinical onset of celiac disease after duodenal switch: a case report.

To our knowledge, this is the first reported case of clinical onset of celiac disease (CD) following duodenal switch surgery. A 61-year-old obese woman developed severe diarrhea soon after bariatric surgery (BS), which was unresponsive to standard medical treatment. After the most common diarrhea etiologies in the immediate postoperative period have been excluded, serological tests were performed. Final diagnosis was determined by anti-tissue transglutaminase antibody positivity. In light of this case report, we propose that CD should be ruled out in any patient presenting with typical or atypical symptoms after BS, regardless of the latency of onset.

Prevalence by sex of preclinical carotid atherosclerosis in newly diagnosed type 2 diabetes.

BACKGROUND AND AIMS: There is clinical trial evidence that only early, intensive risk factor control can reduce cardiovascular disease (CVD) morbidity and mortality in type 2 diabetes (T2DM). However, there is little information regarding preclinical atherosclerosis at diabetes diagnosis. We assessed carotid atherosclerosis in new-onset T2DM and control individuals without prior CVD. METHODS AND RESULTS: In a cross-sectional case-control study, we determined intima-media thickness (IMT) and plaque (IMT ≥1.5 mm) by ultrasound at all carotid sites in new-onset T2DM patients and controls. We assessed 106 T2DM patients, median age 62 years, 46% women, 19% smokers, 54% with hypertension, and 41% with dyslipidemia and 99 non-diabetic subjects matched by age, sex, and cardiovascular risk factors. Compared to controls, T2DM patients had higher common carotid artery (CCA)-IMT (median 0.725 vs. 0.801 mm, p = 0.01), bulb-IMT (0.976 vs. 1.028 mm, p = 0.12), and internal carotid artery (ICA)-IMT (0.727 vs. 0.802 mm, p = 0.04). The prevalence of total plaque (60% vs. 72%, p = 0.06), ICA plaque (20% vs. 42%, p < 0.01), and harboring ≥3 plaques (16% vs. 35% p < 0.01) was also higher in T2DM. Plaque score (sum of maximum plaque heights) was also higher (p < 0.01) in T2DM. Diabetic women showed more advanced carotid atherosclerosis than diabetic men when they were compared with their respective non-diabetic counterparts. CONCLUSIONS: There is a high prevalence of preclinical atherosclerosis (carotid plaque presence and burden) in new-onset T2DM subjects, especially in women. Early, still reversible, preclinical atherosclerosis may explain in part why early intervention is effective to prevent CVD in this patient population.
