ABSTRACT

Background/Aims@#Lactase deficiency, which has many similarities with small intestinal bacterial overgrowth (SIBO), causes various gastrointestinal symptoms. We estimate the prevalence of SIBO in patients with intestinal symptoms from dairy products and investigate the association between lactase deficiency (LD) and SIBO. @*Methods@#This prospective study included patients with functional intestinal symptoms from dairy product indigestion. A questionnaire on gastrointestinal symptoms, a hydrogen (H 2 )-methane glucose breath test (GBT) for SIBO, and lactose intolerance quick test (LQT) for LD using upper gastrointestinal endoscopy were performed. @*Results@#A total of 88 patients, 29 (33.0%) with severe and 36 (40.9%) with mild LD were included. Sixteen patients (18.2%) were GBT positive. Patients with LQT negativity indicating severe LD showed a higher positivity to GBT or GBT (H 2 ) than the historic controls (27.6% vs 6.7%, P = 0.032). There was no difference in the items on the symptom questionnaire according to the presence of LD or SIBO, except for higher symptom scores for urgency in GBT-positive patients. There were more LQT-negative patients in the GBT (H 2 )-positive group than in the other groups (27.6% vs 10.2%, P = 0.036). Moreover, only GBT (H 2 )-positivity was significantly associated with a higher risk of LQT negativity in multivariate analysis (OR, 4.19; P = 0.029). @*Conclusions@#SIBO producing H 2is common in patients with severe LD suspected lactose intolerance. SIBO may be a new therapeutic target for managing intestinal symptoms in patients with lactose intolerance.

ABSTRACT

Background/Aims@#Improving quality of life has been gaining importance in ulcerative colitis (UC) management. The aim of this study was to investigate changes in health-related quality of life (HRQL) and related factors in patients with moderate-to-severe UC. @*Methods@#A multicenter, hospital-based, prospective study was performed using a Moderateto-Severe Ulcerative Colitis Cohort in Korea (the MOSAIK). Changes in HRQL, evaluated using the 12-Item Short Form Health Survey (SF-12) and Inflammatory Bowel Disease Questionnaire (IBDQ), were analyzed at the time of diagnosis and 1 year later. @*Results@#In a sample of 276 patients, the mean age was 38.4 years, and the majority of patients were male (59.8%). HRQL tended to increase in both the IBDQ and SF-12 1 year after diagnosis. A higher partial Mayo score was significantly related to poorer HRQL on the IBDQ and SF-12 in a linear mixed model (p<0.01). Inflammatory markers such as C-reactive protein (CRP) or erythrocyte sedimentation rate also showed a negative correlation on HRQL (p<0.05). Patients whose IBDQ score improved by 16 or more (71.2%) in 1 year were younger, tended to be nonsmokers, and had a lower partial Mayo score and CRP than those whose IBDQ score did not. There was no significant association between HRQL and disease extent, treatments at diagnosis, or the highest treatment step during the 1-year period. @*Conclusions@#Optimally controlled disease status improves HRQL in patients with moderate-tosevere UC. The partial Mayo score and inflammatory markers may be potential indicators reflecting the influence of UC on patient`s daily lives.

ABSTRACT

Background/Aims@#This study aimed to investigate the possibility of in situ diagnosis of Helicobacter pylori (H. pylori) infection during endoscopic examination. The predictive infection value was estimated using the endoscopic Kyoto scoring system (EKSS), and specific endoscopic findings were evaluated for diagnosing H. pylori infection in H. pylori naïve patients and those with a eradication history. @*Materials and Methods@#A total of 836 patients with H. pylori infection were analyzed. The state of the infection was predicted using the EKSS and specific endoscopic findings. @*Results@#Patients were classified into two groups: the H. pylori naïve group and the group with a the bacterial eradication history. The area under the curve (AUC) on receiver operating characteristics analysis was 0.90 for EKSS in H. pylori naïve patients and 0.83 for the other group patients. For patients with open type atrophy and/or intestinal metaplasia, EKSS (24.4%; 95% CI, 12.4~0.3%) and regular arrangement of collecting venules (RAC) (46.3%; 95% CI, 30.7~62.9%) showed low specificities. Mucosal swelling (66.2%; 95% CI, 62.5~69.7%) and sticky mucus (80.5%; 95% CI, 74.8~85.2%) presented relatively high positive predictive values for H. pylori infection in naïve patients, whereas reflux esophagitis, hematin, red streak, and duodenitis exhibited high negative predictive values in patients with a H. pylori eradication history (98.0%; 95% CI, 96.4~99.1%). @*Conclusions@#EKSS and RAC are excellent tools for predicting H. pylori infection. However, they have a limited role in patients with open type atrophy and/or intestinal metaplasia. Specific endoscopic findings could help predict the infection state.

ABSTRACT

Background/Aims@#Local and systemic factors, such as diabetes, obesity, and hyperlipidemia, are considered risk factors for the recurrence of choledocholithiasis after successful endoscopic clearance. Local factors include the presence of bile sludge, common bile duct (CBD) diameter, and CBD angulation. Among them, it is unclear if acute CBD angulation is preferable to the recurrence of a CBD stone. @*Methods@#PubMed, EMBASE, CINAHL, the Cochrane Library databases, and google website were searched for randomized controlled trials reported in English and undertaken until August 2019. Meta‐analysis was performed on all randomized controlled trials for the recurrence of CBD stones between the patients with acute CBD angulation. @*Results@#Eight randomized trials (1,776 patients) were identified, and the total recurrent rate of CBD stones was 18.8% (334/1,776). A CBD angle ≤145° was significantly associated with an increased risk of recurrent CBD stone (OR=2.65, p<0.01). In two prospective studies, acute CBD angulation was not proven to be associated with a recurrence (p=0.39). @*Conclusions@#Approximately 20% of patients with a CBD stone showed recurrence after the complete clearance of the CBD stone, and a CBD angle ≤145° could increase the risk of recurrence. Overall, a large-scale prospective study should be necessary.

ABSTRACT

Acute pancreatitis caused by acute hepatitis A is extremely rare, with only a small number of cases in young adults having been reported. This paper presents a 74-year-old female patient with an acute abdomen, which proved to be acute pancreatitis with acute hepatitis A. A survey of acute viral hepatitis A as a root cause of pancreatitis should be considered when clinicians encounter patients with acute pancreatitis without any known etiology of pancreatitis.

ABSTRACT

The World Health Organization classified rectal neuroendocrine tumors (NETs) as malignant in 2010 owing to their distant metastasis potential. On the other hand, in cases of small rectal NETs (<10 mm), which have a low risk of metastasis, endoscopic removal is the first-line therapeutic option, and regular surveillance is not recommended. The authors report a case of a small, well-differentiated rectal NET, which recurred as multiple hepatic metastases 5 years after apparent complete removal using endoscopic methods.

ABSTRACT

A case of acute pancreatitis associated with hypercalcemia resulting from a newly diagnosed multiple myeloma is reported. There have been several prior reports of hypercalcemia-induced pancreatitis in patients with multiple myeloma, but very few showed the following two aspects: pancreatitis as the first manifestation of hematologic malignancy and recovery after serum calcium levels fell into normal range. When clinicians encounter a patient with hypercalcemic status and acute pancreatitis without any known etiology of pancreatitis, multiple myeloma as a root cause of pancreatitis should be considered.

ABSTRACT

Emphysematous gastritis is a rare form of gastritis caused by infection of the stomach wall by gas forming bacteria. It is a very rare condition that carries a high mortality rate. Portal venous gas shadow represents elevation of intestinal luminal pressure which manifests as emphysematous gastritis or gastric emphysema. Literature reviews show that the mortality rate is especially high when portal venous gas shadow is present on CT scan. Until recently, the treatment of emphysematous gastritis has been immediate surgical intervention. However, there is a recent trend of avoiding surgery because of the frequent occurrence of post-operative complications such as anastomosis leakage. In addition, aggressive surgical treatment has failed to show significant improvement in prognosis. Recently, the authors experienced a case of emphysematous gastritis accompanied by portal venous gas which was treated successfully by conservative treatment without immediate surgical intervention. Herein, we present a case of emphysematous gastritis with concomitant portal venous air along with literature review.

ABSTRACT

Diabetic neuropathic cachexia (DNC) is one of the rarest presentations of diabetic neuropathy associated with profound weight loss. A 50-year-old Korean woman with poorly controlled type 2 diabetes complained of intractable pain in the trunk and lower extremities, and total body weight loss of 17% over a 6 month period. The patient's symptoms persisted after glucose control and various medications for neuropathic pain. A diagnosis of DNC was made based on the rapid onset of severe pain, polyneuropathy, and marked weight loss without evidence of end organ disease other than mild retinopathy, and the exclusion of other possible causes. Spontaneous improvement of the patient's neuropathic pain and gradual weight gain occurred after 6 months of supportive care. Since the original report of DNC, 31 cases have been published in the English-language literature; however, ours is the first reported case in Korea. Clinicians must be aware of this debilitating complication of diabetes because of its severity and rapid progression.

ABSTRACT

This study aimed to investigate the effect of bortezomib in the desensitization and treatment of acute antibody mediated rejection (AAMR) in kidney transplantation. Nine patients who received bortezomib therapy for desensitization (DSZ group, n = 3) or treatment of AAMR (AAMR group, n = 6) were included in this study. In the DSZ group, 2 patients required DSZ owing to positive cross match and 1 owing to ABO mismatch with high baseline anti-ABO antibody titer (1:1,024). Bortezomib was used at 1, 3, 8, and 11 days from the start of the treatment. In the AAMR group, 3 patients showed full recovery of allograft function after bortezomib use and decrease in donor specific anti-HLA antibody (HLA-DSA). However, 3 patients did not respond to bortezomib and experienced allograft failure. In the DSZ group, negative conversion of T-CDC (complement-dependent cytotoxicity) was achieved, and HLA-DSA was decreased to lower than a weak level (median fluorescence intensity [MFI] < 5,000) in 2 patients. In the case of ABO mismatch kidney transplantation, the anti-A/B antibody titer decreased to below the target (< or = 1:16) after bortezomib therapy. Therefore, bortezomib could be an alternative therapeutic option for desensitization and treatment of AAMR that is unresponsive to conventional therapies.

ABSTRACT

BACKGROUND/AIMS: Percutaneous endoscopic gastrostomy (PEG) is a widely-performed procedure for patients undergoing enteral feeding. Due to frequent complications, careful management after the PEG is required. In this study, we investigated the risk factors associated with early exchange of PEG tube. MATERIALS AND METHODS: We did a retrospective survey of 72 patients who received a PEG between January 2009 and April 2014. All patients underwent a tube exchange or removal after the first PEG. Patients who had an exchange within 6 months were defined as 'early exchange' group and the others, as 'late exchange' group. We analyzed the relationship between early exchange and pre-PEG status. RESULTS: Mean age of patients was 67.5+/-18.3 years. The most frequent mental status and performance status before the first procedure, was 'alert' (n=48, 66.7%) and Eastern Cooperative Oncology Group (ECOG) score was 4 (n=28, 39.8%). Mean BMI was 20.2+/-3.7 kg/m2 and the majority of PEG cause was cerebrovascular accidents (n=23, 31.9%). Many patients had a tube exchange (or removal) because of tube dysfunction (n=32, 44.4%). The 'early exchange' group showed a lower BMI than 'late exchange' group (19.7+/-3.57 kg/m2 vs. 22.4+/-3.87 kg/m2, P value 0.009). 'Underweight' (BMI less than 18.5 kg/m2) group was more frequently observed in 'early exchange' group. There was no significant difference in pre-PEG status and post-PEG complication between the 2 groups. CONCLUSIONS: A lower BMI was associated with early exchange of PEG. Health providers should pay attention to the nutritional status of PEG patients.

ABSTRACT

Granulomatosis with polyangiitis (GPA) is a rare antineutrophil cytoplasmic antibody associated with systemic disease characterized by granulomas and vasculitis affecting small and medium vessels. Neurological manifestations in GPA are less frequent than classical manifestations, such as lung and kidney involvement, and cranial nerve palsies are much rarer. Cyclophosphamide and glucocorticoids have been conventionally administered as an initial induction immunosuppressive therapy for GPA. However, increasing evidence has demonstrated the efficacy and safety of rituximab, an anti-B cell monoclonal antibody, for the treatment of GPA. Herein, we describe a successful treatment of relapsing GPA with cranial nerve involvement using rituximab in a 56-year-old male patient who was previously treated with cyclophosphamide plus glucocorticoids.

ABSTRACT

Detection of cystic lesions in the pancreas has increased because of the widespread use of high-resolution diagnostic imaging techniques. Therefore, cystic lesions of the pancreas constitute an increasingly important category with a challenging differential diagnosis. Squamoid cyst of pancreatic ducts is a recently recognized type of cystic lesion in the pancreas in which cystically dilated ducts are lined by non-keratinized squamous epithelium. Although it is clinically known as benign cystic lesion, we experienced its malignant behavior and report here with review of the international literatures.

ABSTRACT

Diabetic ketoacidosis (DKA) is one of the most serious acute metabolic complications of diabetes. The triad of uncontrolled hyperglycemia, metabolic acidosis, and increased total body ketone concentration characterizes DKA. Not all patients with ketoacidosis have DKA, and other situations can result in metabolic acidosis and ketonemia, like starvation ketosis, alcoholic ketoacidosis or ingestion of drugs such as salicylate, methanol, ethylene glycol. We report a case of acetone intoxication that was misdiagnosed as diabetic ketoacidosis.
