Treatment Effect of Phototherapy with Low-Level Energy in Patients with Allergic Rhinitis: A Single-Arm Observational Study.

Allergic rhinitis is one of the most common health challenges and has a chronic and repetitive course that requires symptomatic treatment. We aimed to investigate the effect of phototherapy on allergic rhinitis and how long it takes to demonstrate treatment effect. Twenty-one patients who were diagnosed with allergic rhinitis using the skin prick test were enrolled. Red light (660 nm) and infrared light (940 nm) with a low power energy of 5 mW were used three times a day at intervals of at least 5 h. The Rhinoconjuntivitis Quality of Life Questionnaire (RQLQ) and a visual analog scale (VAS) were used to measure the changes in symptoms. The median RQLQ and VAS scores before treatment were 62 (49-81.5) and 3 (2-5) points, respectively. The RQLQ score improved significantly at two and four weeks after treatment (52 [39-62.5]) and 46.0 [30.5-57.0], respectively). The VAS scores also improved significantly at two and four weeks after treatment. Nasal obstruction and rhinorrhea improved significantly at one week after the procedure. Low-power (5 mW) light irradiation (660 nm red light and 940 nm infrared) was effective in improving the symptoms of allergic rhinitis. In addition, symptom improvement became clear approximately a week after use. Further studies are required to reach a definitive conclusion.

Efficacy and Safety of SID142 in Patients With Peripheral Arterial Disease: A Multicenter, Randomized, Double-Blind, Active-Controlled, Parallel-Group, Phase III Clinical Trial.

PURPOSE: Renexin® is a combination pill of cilostazol and Ginkgo biloba leaf extract that is used for the improvement of ischemic symptoms associated with peripheral arterial disease (PAD). SID142 is a controlled-release tablet of cilostazol (200 mg) and G biloba leaf extract (160 mg) that was developed to address the limitation of BID administration with Renexin. This study aimed to verify that SID142 was not inferior to Renexin in the treatment of patients with PAD. METHODS: This was a multicenter, randomized, double-blind, active-controlled, parallel-group, Phase III clinical trial. Study subjects were randomized to receive SID142 once daily or Renexin twice a day for 12 weeks. The primary end point was a change in the patient assessment of lower leg pain intensity with the use of a visual analog scale (VAS) after 12 weeks of treatment. If the lower limit of the two-sided 95% CI was greater than -10, the study drug was declared noninferior to the reference drug. Secondary efficacy end points included cold sensation, ankle-brachial index, ankle systolic pressure, maximum walking distance, pain-free walking distance, and investigator's global assessment. Study group results were compared 4, 8, and 12 weeks after treatment. Adverse events were assessed as a safety end point. FINDINGS: In total, 344 subjects from 19 medical centers were screened, and a total of 170 subjects were randomly assigned to either the SID142 (n = 86) or the Renexin (n = 84) group. Analysis of the change in lower extremity pain at 12 weeks compared with baseline revealed that SID142 was not inferior to Renexin (21.44 [19.23] vs 22.30 [17.75]; 95% CI, -7.70 to 5.97; P = 0.5942). No significant differences were found between groups in any secondary efficacy end point. However, the incidence of adverse reactions was significantly lower in the SID142 group (22.35% vs 39.29%; P = 0.0171). IMPLICATIONS: SID142 once daily was not inferior to Renexin twice a day for efficacy in patients with PAD. SID142 had a favorable safety profile. CLINICALTRIALS: gov identifier: NCT03318276.

Omega-3 index and smoking in patients with acute ST-elevation myocardial infarction taking statins: a case-control study in Korea.

BACKGROUND: n-3 fatty acids and lifestyle also are closely related to risk of CVD. Most Koreans have higher fish consumption than people of Western populations. However, little is known about the recommended value of omega-3 index in Korean patients with acute ST-elevation myocardial infarction (STEMI) taking statins. Here, we tested the hypothesis that lower omega-3 fatty acids and/or smoking are associated with acute STEMI, even though patients with dyslipidemia who were taking statins and who attained their LDL-C goals. METHODS: We conducted a case-control study in which omega-3 fatty acids and lifestyle factors were determined in 24 consecutive Korean patients taking statins with angiographically confirmed acute STEMI and 68 healthy controls without acute STEMI. The omega-3 index was calculated by the sum of eicosapentaenoic acid and docosahexaenoic acid in erythrocyte membranes. Multivariable adjusted regression analysis was used to assess independent associations between acute STEMI, omega-3 index, and lifestyle factors after adjusting for age, sex, and body mass index (BMI). RESULTS: The mean age of total subjects was 59.9 years, and 57.6% of the subjects were male. The omega-3 index was significantly lower in cases (8.83%) than controls (11.13%; P < 0.001); however, total trans-fatty acids were not different between the two groups. The omega-3 index was inversely associated with odds for being a case (OR 0.16 (95% CI 0.03-1.14); P = 0.047), while smoking was positively associated with odds for being a case (OR 6.67 (95% CI 1.77-25.23); P = 0.005) after adjusting for all confounding variables. CONCLUSION: This study shows that relative to controls, acute STEMI cases are more likely to be smokers and to have a lower omega-3 index, even though the cases were taking statins. An omega-3 index of at least 11% and abstinence from smoking are associated with cardioprotection for Koreans.
