Background and Objectives: Kawasaki disease (KD) is an acute vasculitis that primarily affects children under age 5 years. Approximately 20–25% of untreated children with KD and 3–5% of those treated with intravenous immunoglobulin therapy develop coronary artery aneurysms (CAAs). The prevalence of CAAs is much higher in male than in female patients with KD, but the underlying factors contributing to susceptibility to CAAs in patients with KD remain unclear. This study aimed to identify sex-specific susceptibility loci associated with CAAs in KD patients. Methods: A sex-stratified genome-wide association study (GWAS) was performed using previously obtained GWAS data from 296 KD patients and a new replication study in an independent set of 976 KD patients by comparing KD patients without CAA (controls) and KD patients with aneurysms (internal diameter ≥5 mm) (cases). Results: Six male-specific susceptibility loci, PDE1C, NOS3, DLG2, CPNE8, FUNDC1, and GABRQ (odds ratios [ORs], 2.25–9.98; p=0.00204–1.96×10−6 ), and 2 female-specific susceptibility loci, SMAD3 (OR, 4.59; p=0.00016) and IL1RAPL1 (OR, 4.35; p=0.00026), were significantly associated with CAAs in patients with KD. In addition, the numbers of CAA risk alleles additively contributed to the development of CAAs in patients with KD. Conclusions A sex-stratified GWAS identified 6 male-specific (PDE1C, NOS3, DLG2, CPNE8, FUNDC1, and GABRQ) and 2 female-specific (SMAD3 and IL1RAPL1) CAA susceptibility loci in patients with KD.

Background and Objectives: Sinonasal malignant lymphoma is rare and aggressive. Its low incidence has made detailed studies on epidemiology, survival, and consensus treatment modalities a challenge, and also has limited developing standardized protocols for diagnosis and management. This study analyzes the clinical factors of patients diagnosed with sinonasal malignant lymphoma and their treatment modalities to understand therapeutic outcome and prognostic factors.Subjects and Method The medical records of patients diagnosed between 2011 and 2020 as sinonasal (SN) malignant lymphoma (extranodal NK/T cell lymphoma [ENKTL]/diffuse large B cell lymphoma [DLBCL]) in Seoul national university hospital were retrospectively reviewed. Results: A total 42 patients were included in the study. Of those, 30 patients were SN-ENKTL, 12 patients were SN-DLBCL. The mean age of SN-DLBCL and SN-DLBCL groups was 52.8±14.4, 60.8±12.4, respectively. The main chief complaint was nasal obstruction (54%). Approximately 75% were diagnosed as stage II (Ann-Arbor staging system) and most of the patients received multi-agent chemotherapy or chemoradiotherapy. The 3-year overall survival rate for SN-DLBCL and SN-DLBCL groups was roughly 90%, 88.9%, respectively and the average of disease-free survival period was approximately 41.1 and 22.1 months, respectively, after initiation of treatment. Conclusion We found that sinonasal malignant lymphoma is highly responsive to chemo or chemoradiotherapy. Early accurate diagnosis is important as early-stage patients receiving therapy may benefit from chemo or chemoradiotherapy. Our clinical data showed that in ambiguous situations, wide excision should be considered for diagnosis.

Background: It is well known that a large number of patients with diabetes also have dyslipidemia, which significantly increases the risk of cardiovascular disease (CVD). This study aimed to evaluate the efficacy and safety of combination drugs consisting of metformin and atorvastatin, widely used as therapeutic agents for diabetes and dyslipidemia. Methods: This randomized, double-blind, placebo-controlled, parallel-group and phase III multicenter study included adults with glycosylated hemoglobin (HbA1c) levels >7.0% and <10.0%, low-density lipoprotein cholesterol (LDL-C) >100 and <250 mg/dL. One hundred eighty-five eligible subjects were randomized to the combination group (metformin+atorvastatin), metformin group (metformin+atorvastatin placebo), and atorvastatin group (atorvastatin+metformin placebo). The primary efficacy endpoints were the percent changes in HbA1c and LDL-C levels from baseline at the end of the treatment. Results: After 16 weeks of treatment compared to baseline, HbA1c showed a significant difference of 0.94% compared to the atorvastatin group in the combination group (0.35% vs. −0.58%, respectively; P<0.0001), whereas the proportion of patients with increased HbA1c was also 62% and 15%, respectively, showing a significant difference (P<0.001). The combination group also showed a significant decrease in LDL-C levels compared to the metformin group (−55.20% vs. −7.69%, P<0.001) without previously unknown adverse drug events. Conclusion The addition of atorvastatin to metformin improved HbA1c and LDL-C levels to a significant extent compared to metformin or atorvastatin alone in diabetes and dyslipidemia patients. This study also suggested metformin’s preventive effect on the glucose-elevating potential of atorvastatin in patients with type 2 diabetes mellitus and dyslipidemia, insufficiently controlled with exercise and diet. Metformin and atorvastatin combination might be an effective treatment in reducing the CVD risk in patients with both diabetes and dyslipidemia because of its lowering effect on LDL-C and glucose.
