BACKGROUND: Secukinumab, a fully human monoclonal antibody that targets interleukin (IL)-17A, which is a central cytokine in the pathogenesis of psoriasis, has emerged as a promising treatment for moderate to severe psoriasis. However, to date, there are no real-world data for secukinumab in Korean patients with psoriasis. OBJECTIVE: To assess the clinical efficacy and safety of secukinumab in Korean patients with psoriasis. METHODS: Prospective data were gathered during follow-up from 28 consecutive patients with chronic plaque-type psoriasis treated with secukinumab for minimum of 12 weeks at a single referral center. Patient demographics, Psoriasis Area Severity Index (PASI) score, Physicians' Global Assessment (PGA), Dermatologic Life Quality Index (DLQI), and adverse events were investigated. RESULTS: The mean PASI score was significantly decreased after the induction period of secukinumab treatment (paired t-test, p<0.05). Of the 28 patients, 17 (60.7%) had obtained near complete clearance (PASI 90) at the last follow-up visit. No unexpected adverse events, other than nasopharyngitis, were observed. CONCLUSION: Secukinumab can be of benefit for the treatment of Korean patients with psoriasis, as the treatment was associated with a rapid and satisfactory response and safety profile.

STUDY DESIGN: Retrospective study. PURPOSE: Associations among risk factors related to adjacent segmental disease (ASD) remain unclear. We evaluated the risk factors and segmental lordosis ratio to prevent ASD developing after lumbar spinal fusion. OVERVIEW OF LITERATURE: Risk factors related to ASD development are age, sex, obesity, pre-existing degeneration, number of fusion segments, and decreased postoperative lumbar lordosis (LL). However, the associations among these factors are still unclear and should be clearly identified. METHODS: We retrospectively reviewed data on 274 patients who underwent lumbar spinal fusion of three segments or below for lumbar degenerative disease from January 2010 to December 2012, with over 5 years of follow-up. Patients with preoperative sagittal vertical axis (SVA) >5 cm were excluded due to sagittal imbalance. A total of 37 patients with ASD and 40 control patients (CTRL) were randomly selected in a similar distribution of matching variables: age, sex, and preoperative degenerative changes. Sex, age, number of fusion segments, radiologic measurements, L4–5–S1/L1–S1 LL ratio, and spinopelvic parameters (pelvic incidence [PI], pelvic tilt [PT], sacral slope [SS], and SVA) were analyzed. Logistic regression was used to analyze the correlation between PI–LL mismatch and L4–5–S1 segmental lordosis rate. RESULTS: No significant difference was found between ASDs and CTRL groups regarding age, sex, number of fusion segments, fusion method, and preoperative and postoperative spinopelvic parameters (PI, SS, PT, and LL). However, regarding the L4–5–S1/L1–S1 lordosis ratio, 50% (p=0.045), 60% (p=0.031), 70% (p=0.042), 80% (p=0.023), and 90% (p=0.023) were statistically significant; <20% (p=0.478), 30% (p=0.223), and 40% (p=0.089) were not statistically significant. In the postoperative PI–LL <10 group, ASD occurred less frequently than in the PI–LL >10 group, and the difference was statistically significant (p=0.048). CONCLUSIONS: Patients with a postoperative L4–5–S1/L1–S1 lordosis ratio >50% had less occurrence of ASD. Correcting LL according to PI and physiologic segmental lordosis ratio is important in preventing ASD.

Infective endocarditis (IE) is not a common cause of stroke. Considering the high mortality rates, however, IE should always be considered as a possible cause of stroke even when the chances are low. Atrioesophageal fistula is a life-threatening condition that can cause IE and subsequent stroke, but the diagnosis is often delayed due to its rarity. We report a case of multiple embolic infarcts caused by infective endocarditis associated with atrioesophageal fistula after radiofrequency catheter ablation for atrial fibrillation.

Unilateral linear capillaritis (ULC) is a rare variant of pigmented purpuric dermatosis (PPD). ULC is clinically characterized by unilateral linear macules on the lower extremities, which fade spontaneously. We present three patients with linearly distributed purpuric macules on only one side of the lower extremities. Skin biopsy showed histopathological features of PPDs. We diagnosed ULC based on these clinicopathological findings. For all patients, the skin lesions began to fade spontaneously within several months to a few years after onset. ULC has been reported rarely, with only about 20 cases worldwide and no cases described in the Korean literature.

PURPOSE: Little is known about the clinical value of peripheral blood immune profiling. Here, we aimed to identify colorectal cancer (CRC)-related peripheral blood immune cells and develop liquid biopsy-based immune profiling models for CRC diagnosis. METHODS: Peripheral blood from 131 preoperative patients with CRC and 174 healthy controls was analyzed by flow cytometry and automated hematology. CRC-related immune factors were identified by comparing the mean values of immune cell percentages and counts. Subsequently, CRC diagnostic algorithms were constructed using binary logistic regression. RESULTS: Significant differences were observed in percentages and counts of white blood cells, lymphocytes, neutrophils, regulatory T cells, and myeloid-derived suppressor cells (MDSCs) of patients and controls. The neutrophil/lymphocyte and Th1/Th2 ratios were also significantly different. Likewise, the percentages and counts of peripheral blood programed death 1, cytotoxic T lymphocyte antigen 4, B-and T-lymphocyte attenuator, and lymphocyte activation gene-3 were higher in patients with CRC. The binary logistic regression model included 12 variables, age, CD3+%, NK%, CD4+CD279+%, CD4+CD25+%, CD4+CD152+%, CD3+CD366+%, CD3+CD272+%, CD3+CD223+%, CD158b−CD314+CD3−CD56+%, Th2%, and MDSCs cells/µL, for the prediction of cancer. Results of retrospective and prospective evaluation of the area under the curve, sensitivity, and specificity were 0.980 and 0.940, 91.53% and 85.80%, and 93.50% and 86.20%, respectively. CONCLUSION: Peripheral blood immune profiling may be valuable in evaluating the immunity of CRC patients. Our liquid biopsy-based immune diagnostic method and its algorithms may serve as a novel tool for CRC diagnosis. Future largescale studies are needed for better characterization of its diagnostic value and potential for clinical application.
