ABSTRACT

Objective@#To develop an objective and quantitative clinical evaluation tool that can be used for diagnosis and severity assessment of dysarthria in patients with stroke. @*Methods@#A prototype test comprising 23 items was developed to test the function of each speech organ. The scoring of the prototype test was based on the analysis of the result values obtained from 50 healthy individuals. The test was performed for 50 patients with stroke who were suspected to have dysarthria. For evaluating the correlation between each prototype test item and the Urimal Test of Articulation and Phonation (U-TAP), the odds ratio was obtained for each result, based on which the final test items for composing the Korea Dysarthria Test (KDT) were selected. The validity of the test was evaluated using the receiver operator characteristic (ROC) curve and the area under the curve. We used the intraclass correlation coefficients to quantify inter- and intra-rater reliability. The Spearman correlation coefficient was used for examining the correlation between the KDT and the Speech Mechanism Screening Test and U-TAP. @*Results@#Among the 23 prototype test items, 16 exhibiting significant results were finally selected as the KDT. The higher score of the KDT is reflected the better speaking function. The sensitivity and specificity of the KDT were shown to be high at the cutoff value of 76.50 point. @*Conclusion@#KDT is a useful evaluation tool for dysarthria, showing a significant correlation with SMST and U-TAP.

ABSTRACT

Background/Aims@#This study assessed the efficacy and safety of adalimumab (ADA) and explored predictors of response in Korean patients with ulcerative colitis (UC). @*Methods@#A prospective, observational, multicenter study was conducted over 56 weeks in adult patients with moderately to severely active UC who received ADA. Clinical response, remission, and mucosal healing were assessed using the Mayo score. @*Results@#A total of 146 patients were enrolled from 17 academic hospitals. Clinical response rates were 52.1% and 37.7% and clinical remission rates were 24.0% and 22.0% at weeks 8 and 56, respectively. Mucosal healing rates were 39.0% and 30.1% at weeks 8 and 56, respectively. Prior use of anti-tumor necrosis factor-α (anti-TNF-α) did not affect clinical and endoscopic responses. The ADA drug level was significantly higher in patients with better outcomes at week 8 (P<0.05). In patients with lower endoscopic activity, higher body mass index, and higher serum albumin levels at baseline, the clinical response rate was higher at week 8. In patients with lower Mayo scores and C-reactive protein levels, clinical responses, and mucosal healing at week 8, the clinical response rate was higher at week 56. Serious adverse drug reactions were identified in 2.8% of patients. @*Conclusions@#ADA is effective and safe for induction and maintenance in Korean patients with UC, regardless of prior anti-TNF-α therapy. The ADA drug level is associated with the efficacy of induction therapy. Patients with better short-term outcomes were predictive of those with an improved long-term response.

ABSTRACT

Background/Aims@#Infliximab (IFX) has proven effective as rescue therapy in steroid-refractory acute severe ulcerative colitis (ASUC), however, the long-term real-world data are scarce. Our study aimed to assess the long-term treatment outcomes of IFX in a real-life cohort. @*Methods@#We established a multicenter retrospective cohort of hospitalized patients with ASUC, who met Truelove and Witt’s criteria and received intravenous corticosteroid (IVCS) or IFX during index hospitalization between 2006 and 2016 in 5 university hospitals in Korea. The cohort was systematically followed up until colectomy, death or last follow-up visit. @*Results@#A total of 296 patients were followed up for a mean of 68.9 ± 44.0 months. During index hospitalization, 49 patients were treated with IFX; as rescue therapy for IVCS failure in 37 and as first-line medical therapy for ASUC in 12. All patients treated with IFX avoided colectomy during index hospitalization. The cumulative rates of rehospitalization and colectomy were 20.4% and 6.1% at 3 months and 39.6% and 18.8% at the end of follow-up, respectively. Patients treated with IFX presented with significantly shorter colectomy-free survival than IVCS responders (P= 0.04, log-rank test). Both cytomegalovirus colitis and Clostridioides difficile infection (CDI) were the significant predictors of colectomy in the overall study cohort (hazard ratios of 6.57 and 4.61, respectively). There were no fatalities. @*Conclusions@#Our real-world cohort study demonstrated that IFX is an effective therapeutic option in Korean patients with ASUC, irrespective of IFX indication. Aggressive vigilance for cytomegalovirus colitis and CDI is warranted for hospitalized patients with ASUC.

ABSTRACT

Background/Aims@#We aimed to evaluate the efficacy and safety of ustekinumab (UST) in the East-Asian population with moderate to severely active ulcerative colitis (UC). @*Methods@#This sub-analysis was conducted on data from East-Asian patients included in the UNIFI program (NCT02407236). UNIFI consisted of two double-blind, placebo-controlled trials: an 8-week induction study and a 44-week randomized withdrawal maintenance study. @*Results@#Of 133 East-Asian patients (Japanese: 107, Korean: 26) who underwent randomization, 131 completed induction study and 111 entered maintenance study. In the maintenance study, 78 patients were randomized. Patients who received UST 130 mg and UST 6 mg/kg showed numerically higher clinical remission at week 8 in the induction study (5/44 [11.4%] and 5/45 [11.1%], respectively) compared with those who received placebo (0/44, 0%). The proportion of patients achieved clinical remission at week 44 was numerically higher in the UST 90 mg q12w group (10/21, 47.6%), but similar in the UST 90 mg q8w group (5/26, 19.2%) compared to placebo (7/31, 22.6%). Serious adverse events were reported in 1 patient in UST 130 mg group, but no patient in UST 6 mg/kg group through week 8 in the induction study, and 1 patient in UST 90 mg q12w group and 5 patients in the UST 90 mg q8w group in the maintenance study. No deaths were reported in East-Asian patients throughout the study. @*Conclusions@#UST induction and maintenance treatments were effective in East-Asian patients with moderate to severe UC; the efficacy and safety profiles were consistent with the overall population.

ABSTRACT

Background/Aims@#The efficacy and safety of vedolizumab in moderate to severely active ulcerative colitis (UC) have been demonstrated in the GEMINI 1 study (NCT00783718). This post-hoc exploratory analysis sought to establish the efficacy and safety of vedolizumab in a subgroup of patients from Asian countries with UC from GEMINI 1. @*Methods@#Efficacy outcomes of interest were clinical response, clinical remission and mucosal healing at week 6 (induction phase); and clinical remission, durable clinical response, durable clinical remission, mucosal healing and glucocorticoid-free remission at week 52 (maintenance phase). Differences in outcome rates between vedolizumab and placebo in Asian countries (Hong Kong, India, Malaysia, Singapore, South Korea, and Taiwan) were assessed using descriptive analyses, and efficacy and safety compared between Asian and non-Asian countries. @*Results@#During induction, in Asian countries (n = 58), clinical response rates at week 6 with vedolizumab and placebo were 55.2% and 24.1%, respectively (difference 31.0%; 95% confidence interval: 7.2%–54.9%). In non-Asian countries (n = 316), response rates at week 6 with vedolizumab and placebo were 45.9% and 25.8%, respectively. During maintenance, in Asian countries, clinical remission rates at 52 weeks with vedolizumab administered every 8 weeks, vedolizumab administered every 4 weeks and placebo were 9.1%, 36.8%, and 31.6%, respectively; corresponding rates for mucosal healing were 45.5%, 47.4%, and 47.4%, respectively. Vedolizumab was well-tolerated; adverse event frequency was comparable in Asian and non-Asian countries. @*Conclusions@#In patients from Asian countries, the efficacy and safety of vedolizumab in treatment of UC were broadly consistent with that in the overall study population.

ABSTRACT

Background/Aims@#Limited data are available regarding psychosocial distress at the time of diagnosis of ulcerative colitis (UC). We investigated the psychosocial burden and factors related to poor health-related quality of life (HRQL) among patients newly diagnosed with moderate-to-severe UC who were affiliated with the nationwide prospective cohort study. @*Methods@#Within the first 4 weeks of UC diagnosis, all patients were assessed using the Hospital Anxiety and Depression Scale (HADS), Work Productivity and Activity Impairment questionnaire, Inflammatory Bowel Disease Questionnaire (IBDQ), and 12-Item Short Form (SF-12) health survey. A multiple linear regression model was used to identify factors associated with HRQL. @*Results@#Between August 2014 and February 2017, 355 patients completed questionnaires. Significant mood disorders requiring psychological interventions, defined by a HADS score ≥11, were identified in 16.7% (anxiety) and 20.6% (depression) of patients. Patients with severe disease were more likely to have presenteeism, loss of work productivity, and activity loss than those with moderate disease (all p<0.05). Significant mood disorders had the strongest negative relationship with total IBDQ score, which indicates disease-specific HRQL (β coefficient: –22.1 for depression and –40.0 for anxiety, p<0.001). The scores of all SF-12 dimensions, which indicate general HRQL, were remarkably decreased in the study population compared indirectly with previously reported scores in the general population. The Mayo score, C-reactive protein level, and white blood cell count showed significant negative associations with the IBDQ score (p<0.05). @*Conclusions@#Psychosocial screening and timely interventions should be incorporated into the initial care of patients newly diagnosed with UC.

ABSTRACT

Objective@#To evaluate the severity of depression, anxiety, associated risk factors, and cognitive distortion in Korean patients with ulcerative colitis (UC) and Crohn’s disease (CD). @*Methods@#This study included 369 patients with inflammatory bowel disease. The severity of depression and anxiety was examined using Patient Health Questionnaire-9 and Hospital Anxiety and Depression Scale. The Anxious Thoughts and Tendencies scale was used to measure catastrophizing tendency. Multivariate regression analyses were performed. @*Results@#The predictors of depression were marital status, anti-tumor necrosis factor-α (TNF-α) agent use, age, and body mass index in UC patients and marital status, disease activity, alcohol use, and employment status in CD patients. For anxiety, sex and marital status were the associated factors in UC patients, whereas steroid use was the only significant predictor in CD patients. Comparing the cognitive distortion level, there were no significant differences between UC and CD patients although there was an increasing tendency according to the severity of depression or anxiety. @*Conclusion@#If patients are accompanied by high levels of depression or anxiety and their associated risk factors including TNF-α agent or steroid use, it is recommended that not only symptoms are treated but also cognitive approach and evaluation be performed.

ABSTRACT

The authors regret an error in the reporting of Inflammatory Bowel Disease Questionnaire (IBDQ) patient-reported outcome data in the manuscript. A data extraction error resulted in incorrect IBDQ data being presented in the publication. The error does not affect the overall conclusions regarding IBDQ as the difference between the corrected and erroneous numbers is, in general, small. The error was specific to IBDQ data; all other data have been reviewed and are correct as originally reported.

ABSTRACT

BACKGROUND/AIMS: Tofacitinib is an oral, small-molecule Janus kinase inhibitor being investigated for ulcerative colitis (UC). In OCTAVE Induction 1 and 2, patients with moderately to severely active UC received placebo or tofacitinib 10 mg twice daily (BID) for 8 weeks. Clinical responders in OCTAVE Induction were re-randomized to 52 weeks' therapy with placebo, tofacitinib 5 mg BID, or tofacitinib 10 mg BID. METHODS: We conducted post-hoc efficacy and safety analyses of East Asian patients in OCTAVE Induction 1 and 2 and OCTAVE Sustain. RESULTS: A total of 121 East Asian (Japan, Korea, and Taiwan) patients were randomized in OCTAVE Induction 1 and 2 (placebo, n=26; tofacitinib 10 mg BID, n=95), and 63 in OCTAVE Sustain (placebo, n=20; tofacitinib 5 mg BID, n=22; tofacitinib 10 mg BID, n=21). At week 8 of OCTAVE Induction 1 and 2, 18.9% of patients (18/95) achieved remission with tofacitinib 10 mg BID versus 3.8% (1/26) with placebo. In OCTAVE Sustain, the week 52 remission rates were 45.5% (10/22), 47.6% (10/21), and 15.0% (3/20) with 5 mg BID, 10 mg BID, and placebo, respectively. Adverse event rates were similar between groups in OCTAVE Induction and numerically higher with tofacitinib in OCTAVE Sustain. Serious adverse event rates were similar across groups in all studies. Infections were numerically more frequent with tofacitinib than placebo. Increases in serum lipid levels were observed with tofacitinib. CONCLUSIONS: In East Asian patients with UC, tofacitinib demonstrated numerically greater efficacy versus placebo as induction and maintenance therapy, with a safety profile consistent with the global study population. ClinicalTrials.gov: NCT01465763; NCT01458951; NCT01458574.

ABSTRACT

Crohn's disease (CD) is a chronic inflammatory bowel disease (IBD) that presents with abdominal pain, weight loss, and diarrhea. Although the etiology has not been fully elucidated, both environmental and genetic causes are known to be involved. In chronic inflammatory conditions such as IBD, B lymphocytes are chronically stimulated, and they induce monoclonal expansion of plasma cells, sometimes resulting in monoclonal gammopathy of undetermined significance. Immunomodulators that are commonly used to control inflammation, such as tumor necrosis factor-α (TNF-α) blockers could increase the possibility of hematologic malignancy. The pathogenesis of multiple myeloma in association with TNF-α inhibitor therapy is attributed to decreased apoptosis of plasma cell populations. Here, we describe a case of a 36-year-old male patient who was diagnosed with immunoglobulin A subtype smoldering multiple myeloma during the treatment for CD with infliximab and adalimumab. We report this case along with a review of the literature on cases of multiple myeloma that occurred in conjunction with CD.

ABSTRACT

OBJECTIVE: To investigate the relationship between electrodiagnosis and various ultrasonographic findings of carpal tunnel syndrome (CTS) and propose the ultrasonographic standard that has closest consistency with the electrodiagnosis. METHODS: Ultrasonography was performed on 50 female patients (65 cases) previously diagnosed with CTS and 20 normal female volunteers (40 cases). Ultrasonography parameters were as follows: cross-sectional area (CSA) and flattening ratio (FR) of the median nerve at the levels of hamate bone, pisiform bone, and lunate bone; anteroposterior diameter (AP diameter) of the median nerve in the carpal tunnel; wrist to forearm ratio (WFR) of median nerve area at the distal wrist crease and 12 cm proximal to distal wrist crease; and compression ratio (CR) of the median nerve. Independent t-test was performed to compare the ultrasonographic findings between patient and control groups. Significant ultrasonographic findings were compared with the electrodiagnosis results and a kappa coefficient was used to determine the correlation. RESULTS: CSA and FR of median nerve at the hamate bone level, CSA of median nerve at pisiform bone level, AP diameter of median nerve within the carpal tunnel, CSA of median nerve at the distal wrist crease and WFR showed significant differences between patient and control groups. WFR showed highest concordance with electrodiagnosis (κ=0.71, p<0.001). CONCLUSION: These findings suggested the applicability of ultrasonography, especially WFR, as a useful adjunctive tool for diagnosis of CTS.

ABSTRACT

PURPOSE: Infliximab is currently used for the treatment of active Crohn's disease (CD). We aimed to assess the efficacy and safety of infliximab therapy and to determine the predictors of response in Korean patients with CD. MATERIALS AND METHODS: A total of 317 patients who received at least one infliximab infusion for active luminal CD (n=198) and fistulizing CD (n=86) or both (n=33) were reviewed retrospectively in 29 Korean referral centers. Clinical outcomes of induction and maintenance therapy with infliximab, predictors of response, and adverse events were evaluated. RESULTS: In patients with luminal CD, the rates of clinical response and remission at week 14 were 89.2% and 60.0%, respectively. Male gender and isolated colonic disease were associated with higher remission rates at week 14. In week-14 responders, the probabilities of sustained response and remission were 96.2% and 93.3% at week 30 and 88.0% and 77.0% at week 54, respectively. In patients with fistulizing CD, clinical response and remission were observed in 85.0% and 56.2% of patients, respectively, at week 14. In week-14 responders, the probabilities of sustained response and remission were 94.0% and 97.1%, respectively, at both week 30 and week 54. Thirty-nine patients (12.3%) experienced adverse events related to infliximab. Serious adverse events developed in 19 (6.0%) patients including seven cases of active pulmonary tuberculosis. CONCLUSION: Infliximab induction and maintenance therapy are effective and well tolerable in Korean patients with luminal and fistulizing CD. However, clinicians must be aware of the risk of rare yet critical adverse events.

ABSTRACT

BACKGROUND/AIMS: Two comparable anti-tumor necrosis factor (TNF) agents with different routes of administration (intravenous [iv] infliximab [IFX] vs subcutaneous [sc] adalimumab [ADA]) are available for patients with Crohn's disease (CD) in Korea. This study aimed to identify the preferences of Korean CD patients for a specific anti-TNF agent and the factors contributing to the decision. METHODS: A prospective survey was performed among anti-TNF-naive CD patients in 10 tertiary referral hospitals. A 16-item questionnaire addressed patient preferences and the factors contributing to the decision in favor of a particular anti-TNF agent. A logistic regression was conducted to assess predictive factors for ADA preference. RESULTS: Overall, 189 patients (139 males; mean age, 32.47±11.71 years) completed the questionnaire. IFX and ADA were preferred by 63.5% (120/189) and 36.5% (69/189) of patients, respectively. The most influential reason for choosing IFX was ‘doctor's presence' (68.3%, 82/120), and ADA was “easy to use” (34.8%, 24/69). Amid various clinicodemographic data, having a >60-minute travel time to the hospital was a significant independent predictive factor for ADA preference. CONCLUSIONS: A large number of anti-TNF-naive Korean patients with CD preferred anti-TNFs with an iv route of administration. The reassuring effect of a doctor's presence might be the main contributing factor for this decision.

ABSTRACT

BACKGROUND/AIMS: We investigated whether sodium picosulfate with magnesium citrate (SPMC) plus bisacodyl compares favorably with conventional polyethylene glycol (PEG) with respect to bowel cleansing adequacy, compliance, and safety. METHODS: We performed a multicenter, prospective, single-blinded study in outpatients undergoing daytime colonoscopies. Patients were randomized into a split preparation SPMC/bisacodyl group and a conventional split PEG group. We compared preparation adequacy using the Boston bowel preparation scale (BBPS), ease of use using a modified Likert scale (LS), compliance/satisfaction level using a visual analogue scale (VAS), and safety by monitoring adverse events during the colonoscopy between the two groups. RESULTS: A total of 365 patients were evaluated by intention to treat (ITT) analysis, and 319 were evaluated by per protocol (PP) population analysis (153 for SPMC/bisacodyl, 166 for PEG). The mean total BBPS score was not different between the two groups in both the ITT and PP analyses (p>0.05). The mean VAS score for satisfaction and LS score for the ease of use were higher in the SPMC/bisacodyl group (p<0.001). The adverse event rate was lower in the SPMC/bisacodyl group than in the PEG group (p<0.05). CONCLUSIONS: The SPMC/bisacodyl treatment was comparable to conventional PEG with respect to bowel preparation adequacy and superior with respect to compliance, satisfaction, and safety.

ABSTRACT

OBJECTIVE: To evaluate the potential feasibility of application of the extended International Classification of Functioning, Disability and Health (ICF) Core Set for stroke. METHODS: We retrospectively reviewed the medical records of 40 stroke outpatients (>6 months after onset) admitted to the Department of Rehabilitation Medicine for comprehensive rehabilitation. Clinical information of the patients were respectively evaluated to link to the 166 second-level categories of the extended ICF Core Set for stroke. RESULTS: Clinical information could be linked to 111 different ICF categories, 58 categories of the body functions component, eight categories of the body structures component, 38 categories of the activities and participation component, and seven categories of the environmental factors component. CONCLUSION: The body functions component might be feasible for application of the extended ICF Core Set for stroke to clinical settings. The activities and participation component and environmental factors component may not be directly applied to clinical settings without additional evaluation tools including interview and questionnaire.

ABSTRACT

OBJECTIVE: To develop a quantitative and organ-specific practical test for the diagnosis and treatment of dysphagia based on assessment of stroke patients. METHODS: An initial test composed of 24 items was designed to evaluate the function of the organs involved in swallowing. The grading system of the initial test was based on the analysis of 50 normal adults. The initial test was performed in 52 stroke patients with clinical symptoms of dysphagia. Aspiration was measured via a videofluoroscopic swallowing study (VFSS). The odds ratio was obtained to evaluate the correlation between each item in the initial test and the VFSS. A polychotomous linear logistic model was used to select the final test items. RESULTS: Eighteen of 24 initial items were selected as significant for the final tests. These 18 showed high initial validity and reliability. The Spearman correlation coefficient for the total score of the test and functional dysphagia scale was 0.96 (p<0.001), indicating a statistically significant positive correlation. CONCLUSION: This study was carried out to design a quantitative and organ-specific test that assesses the causes of dysphagia in stroke patients; therefore, this test is considered very useful and highly applicable to the diagnosis and treatment of dysphagia.

ABSTRACT

BACKGROUND/AIMS: Emerging data indicate that polymorphic sequence variations in the tumor necrosis factor alpha (TNF-alpha) gene may affect its production, and be associated with the risk of inflammatory bowel disease (IBD). PRKCDBP is a putative tumor suppressor gene and a transcriptional target of TNF-alpha. The aim of this case-control study is to explore the possible association of single nucleotide polymorphisms (SNPs) in PRKCDBP with the development of IBD in Koreans. METHODS: Genotyping analysis of four SNPs of PRKCDBP [rs35301211 (G210A), rs11544766 (G237C), rs12294600 (C797T), and rs1051992 (T507C)] was performed on 170 ulcerative colitis (UC),131 Crohn's disease (CD) patients, and 100 unrelated healthy controls using polymerase chain reaction and restriction fragment length polymorphism. RESULTS: Heterozygous configuration of three SNPs (G210A, G237C, and C797T) was very rare in both patients and healthy controls. However, allele frequencies of the T507C SNP showed a significant difference between UC patients and controls (P=0.037). The CC genotype of the T507C SNP was identified in 46.6% (61 of 131) of CD and 49.4% (84 of 170) of UC patients, but only in 33.0% (33 of 100) of healthy controls. Furthermore, CC homozygosity was more prevalent than TC heterozygosity in both CD and UC patients versus controls (P=0.016; gender-adjusted odds ratio [aOR], 2.16; 95% confidence interval [CI], 1.16-4.04 and P=0.009; aOR, 2.09; 95% CI, 1.193.64; respectively) CONCLUSIONS: Our results suggest that the T507C SNP in PRKCDBP, a TNF-alpha-inducible gene, might be associated with susceptibility to IBD (particularly UC) development in Koreans.

ABSTRACT

STUDY DESIGN: A retrospective comparative study. PURPOSE: To provide an ideal correction angle of lumbar lordosis (LL) in degenerative flat back deformity. OVERVIEW OF LITERATURE: The degree of correction in degenerative flat back in relation to pelvic incidence (PI) remains controversial. METHODS: Forty-nine patients with flat back deformity who underwent corrective surgery were enrolled. Posterior-anterior-posterior sequential operation was performed. Mean age and mean follow-up period was 65.6 years and 24.2 months, respectively. We divided the patients into two groups based on immediate postoperative radiographs-optimal correction (OC) group (PI-9degrees or =55degrees). Radiological and clinical results were analyzed. RESULTS: Patients in OC group had significantly less correction loss and maintained normal sagittal alignment (sagittal vertical axis<5 cm), as compared to patients in UC group (p<0.05). LL of low PI group significantly maintained within 9degrees better than high PI group (p<0.05). Oswestry disability index (ODI) significantly decreased at last follow-up, as compared to preoperative state. However, there was no significant difference in last follow-up ODI between the groups. CONCLUSIONS: In flat back deformity, correction of LL to within 9degrees of PI will result in better sagittal balance. Thus, we recommend sufficient LL to prevent correction loss, especially in patients with high PI.

ABSTRACT

Despite the increasing use of alternative analgesic agents, salicylate overdose remains a not-uncommon problem. Severe poisoning is life threatening, so prompt treatment and supportive measures are required to reduce mortality. Generally, salicylate intoxication results in the development of high-anion-gap metabolic acidosis. However, outside of Korea, normal-anion-gap or negative-anion-gap metabolic acidosis with hyperchloremia is rarely reported. We report herein the case of an 83-year-old female patient with chronic aspirin intake who presented with hyperchloremia and a negative anion gap. The patient's symptoms improved with conservative treatment and hemodialysis; notably, her chloride levels decreased as her blood salicylate concentrations decreased. Salicylate may cause hyperchloremia, demonstrating the importance of careful documentation of patient medication histories.
