BACKGROUND: There is no randomized controlled study about the effects of end-effector robot-assisted gait training (RAGT) in patients with spinal cord injury (SCI). OBJECTIVE: To examine the effects of end-effector RAGT on gait and balance abilities in SCI. METHODS: Thirty-one patients were randomly assigned to the RAGT (Morning Walk®, Curexo, Seoul, South Korea) or conventional therapy (CT) group. Patients were assessed using the 10-meter walk test (10MWT), 6-minute walk test (6mWT), lower extremity motor score (LEMS) and proprioception, Berg Balance Scale (BBS), Walking Index for Spinal Cord Injury-II (WISCI-II), and mobility category of Spinal Cord Independence Measure-III. RESULTS: All clinical outcome measures significantly improved in both groups. The BBS and WISCI-II were significantly improved in the RAGT group compared to the CT group. In the RAGT group, pre-LEMS and pre-WISCI-II of the 10MWT improved group and pre-BBS of the 6mWT improved group were higher than those of the 10MWT non-improved and 6mWT non-improved group, respectively. CONCLUSION: End-effector RAGT and CT in patients with incomplete SCI could lead to improvements in gait ability, lower extremity muscle strength, balance, proprioception, and mobility. Additionally, end-effector RAGT could improve balance and gait abilities substantially better than CT.

Tenofovir disoproxil fumarate (TDF) is reportedly superior or at least comparable to entecavir (ETV) in preventing hepatocellular carcinoma (HCC) among chronic hepatitis B (CHB) patients; however, it remains controversial. This study aimed to conduct comprehensive comparisons between the two antivirals. CHB patients initially treated with ETV or TDF between 2012 and 2015 at 20 referral centers in Korea were included. The primary outcome was the cumulative incidence of HCC. The secondary outcomes included death or liver transplantation, liver-related outcome, extrahepatic malignancy, development of cirrhosis, decompensation events, complete virologic response (CVR), seroconversion rate, and safety. Baseline characteristics were balanced using the inverse probability of treatment weighting (IPTW). Overall, 4210 patients were enrolled: 1019 received ETV and 3191 received TDF. During the median follow-ups of 5.6 and 5.5 years, 86 and 232 cases of HCC were confirmed in the ETV and TDF groups, respectively. There was no difference in HCC incidence between the groups both before (p = 0.36) and after IPTW was applied (p = 0.81). Although the incidence of extrahepatic malignancy was significantly higher in the ETV group than in the TDF group before weighting (p = 0.02), no difference was confirmed after IPTW (p = 0.29). The cumulative incidence rates of death or liver transplantation, liver-related outcome, new cirrhosis development, and decompensation events were also comparable in the crude population (p = 0.24-0.91) and in the IPTW-adjusted population (p = 0.39-0.80). Both groups exhibited similar rates of CVR (ETV vs. TDF: 95.1% vs. 95.8%, p = 0.38), and negative conversion of hepatitis B e antigen (41.6% vs. 37.2%, p = 0.09) or surface antigen (2.8% vs. 1.9%, p = 0.10). Compared to the ETV group, more patients in the TDF group changed initial antivirals due to side effects, including decreased kidney function (n = 17), hypophosphatemia (n = 20), and osteoporosis (n = 18). In this large-scale multicenter study, ETV and TDF demonstrated comparable effectiveness across a broad range of outcomes in patients with treatment-naïve CHB during similar follow-up periods.
RESUMEN
BACKGROUND: Severe coronavirus disease 2019 (COVID-19) infection may decrease respiratory and physical functions. OBJECTIVE: To evaluate whether robot-assisted stair climbing training (RASCT) would improve pulmonary and physical functions in a patient post-severe COVID-19 infection. CASE DESCRIPTION: A 48-year-old woman who had experienced severe COVID-19 underwent a 6-week inpatient rehabilitation. She persistently exhibited impaired pulmonary and physical functions, including walking and balance impairment. We provided a 30-min outpatient RASCT biweekly for 6 weeks. OUTCOMES: After training, maximal inspiratory and maximal expiratory pressures improved from 81 and 74 cmH2O to 104 and 81 cmH2O, respectively. The walking speed improved from 1.15 to 1.21 m/s. In balance ability, physical performance battery score and timed up-and-go test improved from 8 to 11 s and 10.89 to 9.95 s, respectively. Regarding exercise capacity, the 6-min walk test distance improved from 453 to 482 m, and the number of 1-min sit-to-stand test improved from 20 to 23, with improved pulse rate and saturation level. The physical and psychological domain scores of the World Health Organization Quality-of-Life Scale-BREF improved from 44 to 63 and 69 to 81, respectively; Falls Efficacy Scale-International scores improved from 38 to 21. CONCLUSION: RASCT, as part of a rehabilitation plan, was feasible and effective for this patient after severe COVID-19 infection.
RESUMEN
Purpose: Tenofovir disoproxil (TD), modified from tenofovir disoproxil fumarate (TDF), was developed as a salt-free formulation, removing fumarate to improve the ease of oral intake by reducing the tablet's size. We evaluated the maintenance of antiviral effects and overall safety profile of TD 245 mg after switching from TDF 300 mg in patients with chronic hepatitis B (CHB). Patients and Methods: CHB patients with HBV-DNA <69 IU/mL after ≥24 weeks of TDF therapy were enrolled. The primary efficacy endpoint was the HBV-DNA suppression rate (HBV-DNA <69 IU/mL) at week 48; We evaluated the non-inferiority (10% margin) of TD to TDF in terms of efficacy. Safety was assessed based on adverse events (AEs), laboratory tests, bone mineral density, and renal function abnormalities. Results: Overall, 189 subjects were randomized in a 2:1 ratio, and 117 and 66 subjects in the TD and TDF groups, respectively, completed the study. In the per-protocol set, the HBV-DNA suppression rate at week 48 was 99.1% and 100% in the TD and TDF groups, respectively. The lower limit of the 97.5% one-sided confidence interval for the intergroup difference in HBV-DNA suppression rate was -2.8%, which was greater than the prespecified margin of non-inferiority. The changes in creatinine clearance from baseline to week 48 was significantly less in the TD group and in the TDF group; -0.8 ± 9.8 versus -2.4 ± 12.8 mL/min, respectively (P=0.017). Conclusion: TD was non-inferior to TDF for maintaining viral suppression in CHB patients, showing the less decline of renal function.

BACKGROUND: Tenofovir disoproxil fumarate (TDF, Viread®) had been used as a standard treatment option of chronic hepatitis B (CHB). This clinical trial was conducted to evaluate the efficacy and safety of DA-2802 (tenofovir disoproxil orotate) compared to TDF. METHODS: The present study was a double blind randomized controlled trial. Patients with CHB were recruited from 25 hospitals in Korea and given DA-2802 at a dose of 319 mg once daily or Viread® at a dose of 300 mg once daily for 48 weeks from March 2017 to January 2019. Change in hepatitis B virus (HBV) DNA level at week 48 after dosing compared to baseline was the primary efficacy endpoint. Secondary efficacy endpoints were proportions of subjects with undetectable HBV DNA, those with normal alanine aminotransferase (ALT) levels, and those with loss of hepatitis B envelop antigen (HBeAg), those with loss of hepatitis B surface antigen (HBsAg). Adverse events (AEs) were also investigated. RESULTS: A total of 122 patients (DA-2802 group: n = 61, Viread® group: n = 61) were used as full analysis set for efficacy analysis. Mean age, proportion of males, laboratory results and virologic characteristics were not different between the two groups. The change in HBV DNA level at week 48 from baseline was -5.13 ± 1.40 in the DA-2802 group and -4.97 ± 1.40 log10 copies/mL in the Viread® group. The analysis of primary endpoint using the nonparametric analysis of covariance showed statistically significant results (P < 0.001), which confirmed non-inferiority of DA-2802 to Viread® by a prespecified noninferiority margin of 1. The proportion of undetectable HBV DNA was 78.7% in the DA-2802 group and 75.4% in the Viread® group (P = 0.698). The proportion of subjects who had normal ALT levels was 75.4% in the DA-2802 group and 73.3% in the Viread® group (P = 0.795). The proportion of those with HBeAg loss was 8.1% in the DA-2802 group and 10.8% in the Viread® group (P = 1.000). No subject showed HBsAg loss. The frequency of AEs during treatment was similar between the two groups. Most AEs were mild to moderate in severity. CONCLUSION: DA-2802 is considered an effective and safe treatment for patients with CHB. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02967939.

The primary aim of this study was to reveal the effects of end-effector robot-assisted gait training (RAGT) on motor function, proprioception, balance, and gait ability in patients with incomplete spinal cord injury (SCI). The secondary aim was to determine the correlation between clinical outcomes. This study was a prospective and multi-center study. A total of 13 incomplete SCI patients who met inclusion criteria received 30 min of RAGT with Morning Walk® (Curexo, Seoul, South Korea), and 1 h of conventional physiotherapy 5 times per week for 4 weeks. Clinical outcome measures were 10 m walk test (10MWT), 6 min walk test (6mWT), lower extremity motor score (LEMS), proprioception, Berg Balance Scale (BBS), and Walking Index for Spinal Cord Injury (WISCI)-II. All participants were assessed within 48 h before and after the intervention. All clinical outcomes were statistically improved after RAGT. Subgroup analysis according to the initial proprioception, WISCI-II in the normal group showed a statistically significant improvement compared to the abnormal group. Initial BBS and WISCI-II had a positive correlation with most of the final clinical outcomes. The final BBS had a strong positive correlation with the final 10MWT, 6mWT, and WISCI-II. Initial proprioception had a positive correlation with the final WISCI-II. The final proprioception also had a moderate positive correlation with 6mWT and BBS. This study's results suggest that the end-effector RAGT could promote proprioception, balance ability and walking ability. Postural control ability and proprioception also had a positive relationship with gait ability.
RESUMEN
BACKGROUND AND AIMS: Clinical evidence for the benefits of branched-chain amino acids (BCAAs) is lacking in advanced liver disease. We evaluated the potential benefits of long-term oral BCAA supplementation in patients with advanced liver disease. METHODS: Liver cirrhosis patients with Child-Pugh (CP) scores from 8 to 10 were prospectively recruited from 13 medical centers. Patients supplemented with 12.45 g of daily BCAA granules over 6 months, and patients consuming a regular diet were assigned to the BCAA and control groups, respectively. The effects of BCAA supplementation were evaluated using the model for end-stage liver disease (MELD) score, CP score, serum albumin, serum bilirubin, incidence of cirrhosis-related events, and event-free survival for 24 months. RESULTS: A total of 124 patients was analyzed: 63 in the BCAA group and 61 in the control group. The MELD score (p = 0.009) and CP score (p = 0.011) significantly improved in the BCAA group compared to the control group over time. However, the levels of serum albumin and bilirubin in the BCAA group did not improve during the study period. The cumulative event-free survival was significantly improved in the BCAA group compared to the control group (HR = 0.389, 95% CI = 0.221-0.684, p < 0.001). CONCLUSION: Long-term supplementation with oral BCAAs can potentially improve liver function and reduce major complications of cirrhosis in patients with advanced liver disease.

Robots are being used to assist the recovery of walking ability for patients with neurologic disorders. This study aimed to evaluate the feasibility and functional improvement of training with robot-assisted gait training (RAGT) using the Morning Walk®, an end-effector type robot using footplates and saddle seat support. A total of 189 individuals (65.1% men, 34.9% women; mean age, 53.2 years; age range: 5-87 years) with brain lesions, spinal cord injuries, Parkinson's disease, peripheral neuropathies, and pediatric patients were involved in this retrospectively registered clinical trial. Each participant performed 30 minutes of RAGT, five times a week, for a total of 24 sessions. Failure was defined as an inability to complete all 24 sessions, and the reasons for discontinuation were analyzed. Parameters of Medical Research Council scales and Functional Ambulation Categories were analyzed before and after RAGT training. Among the 189 patients, 22 (11.6%) failed to complete the RAGT. The reasons included decreased cooperation, musculoskeletal pain, saddle seat discomfort, excessive body-weight support, joint spasticity or restricted joint motion, urinary incontinence from an indwelling urinary catheter, and fatigue. Comparison between the pre- and post-training motor and ambulatory functions showed significant improvement. The result of the study indicates that the Morning Walk® is feasible and safe and useful for functional improvement in patients with various neurologic disorders.

RESUMEN
Background/Aims: This study aimed to investigate the epidemiology of hepatitis C virus (HCV) infection in the Korean general population and the awareness and treatment status of HCV infection among anti-HCV-positive persons. Methods: We used data from the Korea National Health and Nutrition Examination Survey (KNHNES) collected between 2012 and 2016. All the participants aged ≥10 years in the KNHNES were tested for the anti-HCV antibody. Anti-HCV-positive persons were tested for HCV RNA and assessed for their awareness and treatment experience regarding HCV infection. Results: The prevalence of anti-HCV was 0.66% (95% confidence interval, 0.56% to 0.78%) among Koreans aged ≥10 years, representing an estimated 278,819 anti-HCV-positive persons, and 0.71% (95% confidence interval, 0.60% to 0.84%) among Koreans aged ≥20 years. The prevalence of anti-HCV increased with age and had significant geographic variation. The positive rate of HCV RNA in anti-HCV-positive persons was 33.5% and increased with age. The rate of HCV infection awareness was 15.2% (35/250) among anti- HCV-positive persons and 30.5% (18/59) among HCV RNApositive persons. Among the participants, 13.5% of HCV RNA-positive persons had been treated for HCV infection. Conclusions: The prevalence of anti-HCV among Koreans aged ≥20 years was 0.71%; one-third of anti-HCV-positive persons tested HCV RNA-positive. The awareness and treatment rates of HCV infection were low among HCV-infected persons. Therefore, active measures should be taken to diagnose and treat persons unaware of HCV infection.

BACKGROUND: Little clinical data are available about the effect of food on the antiviral efficacy of entecavir for chronic hepatitis B virus (HBV) infection. The present study evaluated whether entecavir administration in the fed state had comparable efficacy to the fasted condition for maintenance of viral suppression in HBV-infected patients with virological response on entecavir therapy. METHODS: In this multicenter, randomized, open-label, noninferiority study, patients who were currently receiving entecavir and showed a serum HBV DNA level of <20 IU/mL were randomized to take entecavir either under the fasted or fed condition for 48 weeks. RESULTS: We randomly assigned 50 patients to the fasted group and 46 patients to the fed group. The full analysis set consisted of 49 patients in the fasted group and 44 patients in the fed group. At week 48, the proportion of patients with HBV DNA <20 IU/mL was not significantly different between the fasted and fed groups (98% vs 100%, P=1.00). The mean log10 HBV DNA changes from baseline were similar between the two groups (-0.004 vs -0.012 log10 IU/mL, P=0.43). There were no significant differences in the proportions of patients with normal alanine aminotransferase (87.8% vs 95.5%, P=0.27) and hepatitis B e-antigen seroconversion (0% vs 6.7%, P=0.47) between the two groups. None of the patients showed viral breakthrough. In pharmacokinetic analysis, the maximum concentration and the area under the concentration- time curve to the last quantifiable concentration decreased by 26.4% and 9.3%, respectively, in the fed group compared with the fasted group. However, the differences between two groups were not statistically significant (P=0.28 and 0.83, respectively). CONCLUSION: In patients with virological response under entecavir therapy, concomitant food intake did not affect the antiviral efficacy. For patients with adherence problem, taking entecavir with food may be considered to improve compliance.

Pancreatic metastasis is extremely rare, particularly from small-cell lung cancer (SCLC). Studies on the role of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) with liquid-based cytology (LBC) in the diagnosis of metastatic small-cell carcinoma in the pancreas have been rarely conducted. We report herein a case of pancreatic metastasis from SCLC diagnosed using EUS-FNA with LBC (ThinPrep). A 71-year-old man presented with chief complaints of hemoptysis and jaundice over the past 1 month. Lung & pancreas tumors with multiple liver nodules were detected on computed tomography. The aspirated material from the pancreas using EUS-FNA was prepared as a cytologic specimen with ThinPrep method, which revealed scattered and clustered "small blue cells" with scant cytoplasm and stippled chromatin with frequent apoptotic bodies. Immunocytochemical staining of the cellblock material revealed strong positivity for CD56 and thyroid transcription factor-1. Endobronchial biopsy for lung mass revealed nests of small, round, blue tumor cells with hyperchromatic nuclei showing salt and pepper chromatin, scant cytoplasm, and brisk mitotic activity. Therefore, a diagnosis of metastatic small-cell carcinoma to the pancreas with an extensive stage was finally made.

Purpose: Lyso-thermosensitive liposomal doxorubicin (LTLD) consists of doxorubicin contained within a heat-sensitive liposome. When heated to ≥40°C, LTLD locally releases a high concentration of doxorubicin. We aimed to determine whether adding LTLD improves the efficacy of radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) lesions with a maximum diameter (dmax) of 3 to 7 cm.Experimental Design: The HEAT Study was a randomized, double-blind, dummy-controlled trial of RFA ± LTLD. The 701 enrolled patients had to have ≤4 unresectable HCC lesions, at least one of which had a dmax of 3 to 7 cm. The primary endpoint was progression-free survival (PFS) and a key secondary endpoint was overall survival (OS). Post hoc subset analyses investigated whether RFA duration was associated with efficacy.Results: The primary endpoint was not met; in intention-to-treat analysis, the PFS HR of RFA + LTLD versus RFA alone was 0.96 [95% confidence interval (CI), 0.79-1.18; P = 0.71], and the OS HR ratio was 0.95 (95% CI, 0.76-1.20; P = 0.67). Among 285 patients with a solitary HCC lesion who received ≥45 minutes RFA dwell time, the OS HR was 0.63 (95% CI, 0.41-0.96; P < 0.05) in favor of combination therapy. RFA + LTLD had reversible myelosuppression similar to free doxorubicin.Conclusions: Adding LTLD to RFA was safe but did not increase PFS or OS in the overall study population. However, consistent with LTLD's heat-based mechanism of action, subgroup analysis suggested that RFA + LTLD efficacy is improved when RFA dwell time for a solitary lesion ≥45 minutes.

OBJECTIVE: The aim of this study was to describe the clinical characteristics of acute hemorrhagic rectal ulcer (AHRU) and to elucidate its predictive factors. METHODS: The medical records of patients with AHRU were retrospectively reviewed. Their baseline clinical characteristics were compared with those of patients with non-AHRU lower gastrointestinal bleeding to identify predictive factors for AHRU. RESULTS: Among the 118 patients who underwent emergency endoscopy due to acute massive hematochezia from 2013 to 2015, 25 (21.2%) were diagnosed as having AHRU. Of them, 22 (88.0%) were successfully managed endoscopically and 3 (12.0%) underwent surgery. Six (24.0%) patients developed rebleeding within 1-9 days after the initial bleeding, which was controlled by a repeat endoscopy. Five (20.0%) died during follow-up. A multivariate-adjusted logistic regression analysis revealed that a lower serum albumin level, worse Eastern Cooperative Oncology Group (ECOG) performance status and history of constipation were significant factors for predicting AHRU. Hypoalbuminemia (<30 g/L) had a sensitivity, specificity and positive and negative predictive values of 84.0%, 78.5%, 51.2% and 94.8% for predicting AHRU, respectively. CONCLUSIONS: Approximately 20% of patients with massive hematochezia had AHRU. Most patients with AHRU can be managed endoscopically. Low serum albumin level, poor ECOG performance status and prior constipation could be used in distinguishing patients with and without AHRU, facilitating the selection of optimal bowel preparation method for massive hematochezia.

Pancreatic adenocarcinoma may account for more than 80% of all pancreatic neoplasms. Occasionally, other rare tumors such as lymphoma, metastatic tumor, and solid pseudopapillary neoplasm can be considered in the differential diagnosis. We report the case of an 82-year-old man with a pancreatic solid mass. This case suggests that endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) with biopsy, that is, EUS-FNA is recommended in the differential diagnosis of the pancreatic solid mass apart from pancreatic adenocarcinoma. In particular, the histologic core obtained by EUS-guided biopsy is helpful for the immunostaining of molecular markers to confirm the final diagnosis.
RESUMEN
Evidence of the potential benefits of long-term oral branched-chain amino acid (BCAA) supplementation in reducing the severity of liver disease is limited.Patients who were diagnosed with liver cirrhosis with a Child-Pugh (CP) score of 8-10 were included. The BCAA group consumed BCAAs daily for at least 6 months, and the control group consumed a diet without BCAA. We analyzed the improvements based on the model for end-stage liver disease (MELD) score, CP score, incidence of cirrhosis-related complications, and event-free survival over 2 years. Among the 867 recruited patients, 307 (166 in the BCAA group and 141 in the control group) were analyzed. The BCAA group was divided into 3 subgroups, whose patients consumed 4.15âg, 8.3âg, or 12.45âg of BCAAs daily for the analysis. There were significant differences in the CP score, albumin, and hepatic encephalopathy between the 2 groups at baseline. After matching the propensity scores, we analyzed patients in the BCAA-12.45âg group (12.45âg of BCAAs daily, nâ=â41) and matched control group (nâ=â41). The MELD score significantly improved in the BCCA-12.45âg group compared to the matched control group (Pâ=â.004). The changes in the serum bilirubin level (Pâ=â.014) and CP score (Pâ=â.033) over time also differed significantly between the 2 groups. The incidence rates of cirrhosis-related complications (Pâ=â.973) and development of hepatocellular carcinoma (2 cases each) did not differ significantly between the 2 groups.Long-term oral BCAA supplementation has beneficial effects in patients with advanced liver cirrhosis. A further large-scale prospective study is needed to delineate these beneficial effects.

BACKGROUND/AIMS: To date, the best therapeutic modality for gastric adenoma, especially low-grade adenoma, has not been established. The aim of this study was to assess the usefulness of argon plasma coagulation (APC) in treating gastric adenoma compared with endoscopic submucosal dissection (ESD). METHODS: We included 210 patients with gastric adenoma, who underwent treatment with either APC (97 patients) or ESD (113 patients). The clinical and pathologic characteristics, mean duration of hospital stay, complications, and recurrence rates between the two groups were compared. RESULTS: The mean adenoma size was 0.9 cm and 1.1 cm in the APC group and ESD group, respectively (p<0.001). The mean duration of hospital stay was significantly shorter in the APC group than in the ESD group (1.6 days vs. 5.8 days, p<0.001). Complications did not occur in the APC group. However, one case of perforation (0.9%) and 6 cases of bleeding (5.3%) occurred in the ESD group. The recurrence rates were 15.3% (15/97 patients) in the APC group and 3.5% (4/113 patients) in the ESD group (p=0.003). The proportion of hospitalization was less in the APC group (43.3%, 42/97) than in the ESD group (100.0%, 113/113) (p<0.001). Medical expense was less in the APC group (377,172 won) than in the ESD group (1,430,610 won) (p<0.001). CONCLUSIONS: The findings of this study suggest that APC is a safe treatment method for gastric adenoma without serious complications. However, regular endoscopic follow-up is necessary to detect any residual or recurrent lesions due to the relatively high rate of local recurrence after APC.

BACKGROUND/AIMS: Because of the limited geographic distribution, there have been insufficient data regarding hepatitis C virus (HCV) genotype 6 in Korea. This study aimed to investigate the clinical characteristics and available treatment outcomes of patients with genotype 6 HCV in Korea. METHODS: From 2004 to 2014, data were collected from Korean patients infected with genotype 6 HCV in eight hospitals. RESULTS: Thirty-two patients had genotype 6 HCV. The median age was 44 years, and 6c was the most common subtype. The baseline median alanine transaminase level was 88 (21 to 1,019) IU/mL, and the HCV RNA level was 1,405,000 (96,500 to 28,844,529) IU/mL. Twenty-five patients were treated with peginterferon (PEG-IFN) and ribavirin. Three follow-up losses occurred. Additionally, 13 patients attained a sustained virologic response (SVR), seven patients relapsed, and two patients exhibited a null response. The SVR rates were 40% and 75% for the 24- and more than 48-week treatments, respectively, and five of the six patients who achieved a rapid virologic response (RVR) attained a SVR. CONCLUSIONS: Korean patients infected with genotype 6 HCV are relatively young, and 6c is the most common subtype. When treated with PEG-IFN and ribavirin, the SVR rate was 52%. Similar to other genotypes, a longer duration of treatment and attainment of RVR are important for SVR.

A 57-year-old man with chronic kidney disease and a history of using numerous herbal medications visited Inje University Ilsan Paik Hospital for abdominal pain and vomiting. An abdominal radiograph showed diffuse small bowel distension containing multiple air-fluid levels and extensive calcifications along the colon. Computed tomography showed colon wall thickening with diffuse calcification along the colonic mesenteric vein and colonic wall. Colonoscopy, performed without bowel preparation, showed bluish edematous mucosa from the transverse to the distal sigmoid colon, with multiple scar changes. At the mid transverse colon, a stricture was noted and the scope could not pass through. A biopsy of the stricture site revealed nonspecific changes. The patient was diagnosed with phlebosclerotic colitis. After the colonoscopy, the obstructive ileus spontaneously resolved, and the patient was discharged without an operation. Currently, after 2 months of follow-up, the patient has remained asymptomatic. Herein, we report the rare case of an obstructive ileus caused by phlebosclerotic colitis with a colon stricture.
RESUMEN
Chronic hepatitis C virus (HCV) infection is a major cause of liver cirrhosis and hepatocellular carcinoma. Combination therapy of pegylated interferon-alpha (PEG-IFN-α) and ribavirin (RBV) is a current standard treatment for chronic HCV infection in Korea, which has considerable adverse effects. Acute pancreatitis is a rare complication of PEG-IFN-α administration. We report a case of a 62-year-old female who experienced acute pancreatitis after 4 weeks of PEG-IFN-α-2a and RBV combination therapy for chronic HCV infection. The main cause of the acute pancreatitis in this case was probably PEG-IFN-α rather than RBV for several reasons. A few cases have been reported in which acute pancreatitis occurred during treatment with PEG-IFN-α-2b. This is the first report of acute pancreatitis associated with PEG-IFN-α-2a in Korea.
