Background Histological activity in ulcerative colitis (UC) has been accepted to be associated with clinical outcomes. This study aimed to investigate the association between the histological activity at diagnosis and endoscopic findings, either at diagnosis or at the first follow-up, in patients with UC.
Methods Through a retrospective review of 1 year of medical records, this study evaluated the association between histological and endoscopic activity in 51 patients newly diagnosed with UC at a tertiary hospital in Korea between March 2015 and February 2022. The Nancy histological index was used to assess histological activity, classifying patients into low (0–2) and high (3–4) groups. The Mayo Endoscopic Subscore and the Ulcerative Colitis Endoscopic Index of Severity (UCEIS) were used for endoscopic activity scoring.
Results At diagnosis, UCEIS demonstrated no statistically significant difference histologically (p=0.065), and histological and endoscopic activities were not significantly correlated (r=0.18, p=0.200). During the first follow-up, 40 patients (78.4%) exhibited low histological activity, and the number of patients with high histological activity decreased after treatment. The first follow-up endoscopy revealed that 30 patients (58.8%) achieved an endoscopic response, including 9 (56.2%) and 21 patients (60.0%) in the high and low groups, respectively, with no significant difference (p=0.800). However, the high group at diagnosis demonstrated a positive correlation with UCEIS endoscopic activity during the first follow-up (r=0.37, p<0.001).
Conclusion High histological activity at diagnosis was positively correlated with endoscopic activity at the first follow-up. More active care should be provided to patients with high histological activity during diagnosis.
Synchronous gastric cancer and adenomatous colorectal polyp in patients with Klebsiella pneumoniae-induced pyogenic liver abscess (KP-PLA) and bacteremia is a rare presentation. A 58-year-old man with a 6-month history of diabetes mellitus (DM) presented with febrile sensation and dull abdominal pain in the right upper quadrant of the abdomen. Subsequent to laboratory test results and abdominal computed tomography findings, KP-PLA with bacteremia was diagnosed. After intravenous antibiotic administration, his symptoms improved, and upper endoscopy and colonoscopy were performed to evaluate the cause of KP-PLA. Biopsy specimens of the prepyloric anterior wall revealed a moderately differentiated adenocarcinoma. Endoscopic mucosal resection of the colon revealed high-grade dysplasia. Early gastric cancer (EGC) and adenomatous colorectal polyps with high-grade dysplasia concomitant with KP-PLA and bacteremia were diagnosed in our patient who had DM. Intravenous antibiotic treatment for KP-PLA, subtotal gastrectomy for EGC, and colonoscopic mucosal resection for the colon polyp were performed. After 25 days of hospitalization, subtotal gastrectomy with adjacent lymph node dissection was performed. Follow-up ultrasound imaging showed resolution of the abscess 5 weeks post-antibiotic treatment, as well as no tumor metastasis. Upper gastrointestinal endoscopy and colonoscopy should be performed to evaluate gastric cancer in patients with PLA or bacteremia, accompanied with DM or an immunocompromised condition.

The widely used polyethylene glycol (PEG)-based solutions have been proven effective for bowel preparation when 4 L of the solution is administered before colonoscopy. However, large volumes of the solutions are generally poorly tolerated. A new PEG-based solution consisting of 2 L of PEG and a high dose of ascorbic acid has recently become available. Electrolyte abnormalities caused by PEG-based solutions have rarely been reported. We report on a case of acute severe hyponatremia with associated generalized tonic-clonic seizures after bowel preparation with a low-volume PEG plus ascorbic acid solution in a 74-year-old woman with no history of seizures. She took a beta blocker, an angiotensin-converting enzyme inhibitor, and glimepiride for hypertension and diabetes mellitus. She showed general weakness, nausea, agitation, muscle cramping, and seizures after ingestion of the PEG plus ascorbic acid solution. Her serum sodium level was 112 mEq/L. Her symptoms improved after intravenous administration of hypertonic saline. Physicians should pay attention to screening for electrolytes and development of neurological symptoms during bowel preparation.
