BackgroundObstructive sleep apnea (OSA) is associated with systemic inflammation and induces various comorbid medical diseases. To date, no study has explored the relationship between OSA and atopic dermatitis (AD), an inflammatory and autoimmune skin disorder. This study investigated the longitudinal risk for AD in patients with OSA.MethodsA random sample of 1,000,000 individuals from Taiwan's National Health Insurance database was collected. From this sample, 1222 patients with newly-diagnosed OSA between 2000 and 2005 were identified and compared with a matched cohort of 18330 patients without OSA. All patients were tracked for 5.5 years from the index date in order to identify which patients subsequently developed AD.ResultsDuring the 5.5-year follow-up period, the incidence rates of AD in the OSA cohort and comparison groups were 9.81 and 6.21 per 1000 person-years, respectively. After adjustment for age, gender, diabetes, hypertension, coronary heart disease, obesity, allergy, allergic rhinitis, asthma, monthly income, and geographic location, patients with OSA were 1.5-times more likely to develop AD than patients without OSA (95% CI = 1.15–1.95, p = 0.0025). The hazard risk for AD was greater in male OSA patients and young OSA patients (0–18 and 19–34 years), adjusted HRs being 1.53 (95% CI = 1.14–2.06, p = 0.005), 4.01(95% CI = 1.57–10.26, p = 0.0038) and 1.75(95% CI = 1.00–3.04, p = 0.0483), respectively. The log-rank test indicated that OSA patients <35-years-old had significantly higher cumulative incidence rates of AD than those patient of the same age in the comparison group (p = 0.0001).ConclusionPatients with OSA, especially male patients and younger patients, are at an increased risk for AD later in life.

Transcutaneous electrical nerve stimulator (TENS) has been demonstrated to be beneficial in glycemic control in animal models, but its application in humans has not been well studied. We randomly assigned 160 patients with type 2 diabetes on oral antidiabetic drugs 1:1 to the TENS study device (n = 81) and placebo (n = 79). 147 (92%) randomized participants (mean [SD] age 59 [10] years, 92 men [58%], mean [SD] baseline HbA1c level 8.1% [0.6%]) completed the trial. At week 20, HbA1c decreased from 8.1% to 7.9% in the TENS group (− 0.2% [95% CI − 0.4% to − 0.1%]) and from 8.1% to 7.8% in the placebo group (− 0.3% [95% CI − 0.5% to − 0.2%]) (P = 0.821). Glycemic variability, measured as mean amplitude of glycemic excursion (MAGE) at week 20 were significantly different in the TENS group vs. the placebo group (66 mg/dL [95% CI 58, 73] vs. 79 mg/dL [95% CI 72, 87]) (P = 0.009). Our study provides the clinical evidence for the first time in humans that TENS does not demonstrate a statistically significant HbA1c reduction. However, it is a safe complementary therapy to improve MAGE in patients with type 2 diabetes.

At week 20, HbA1c decreased from 8.1% to 7.9% in the TENS group (-0.2% [95% CI: -0.4% to -0.1%]) and from 8.1% to 7.8% in the placebo group (-0.3% [95% CI: -0.5% to -0.2%]) (P = 0.821). Mean amplitude of glycemic excursion (MAGE) at week 20 were significantly different (66 mg/dL [95% CI: 58, 73] vs. 79 mg/dL [95% CI: 72, 87]) (P = 0.009). Besides, we noticed that hypoglycemia accounted for 6/54 (11%) of total adverse events and 14/46 (30%) in the TENS vs. the placebo groups. Our study provides the clinical evidence for the first time in humans that TENS does not demonstrate a statistically significant HbA1c reduction. However, it is a safe complementary therapy to improve MAGE in patients with type 2 diabetes.
