Glypican-3 level assessed by the enzyme-linked immunosorbent assay is inferior to alpha-fetoprotein level for hepatocellular carcinoma diagnosis

Background/Aims Glypican-3 (GPC3) protein is highly expressed in hepatocellular carcinoma (HCC) tissue. It has been suggested as a diagnostic biomarker, but its inconsistent performance means that it requires further assessment. We therefore investigated the diagnostic value of the plasma GPC3 level compared to the alpha-fetoprotein (AFP) level as a diagnostic biomarker of HCC. Methods We enrolled 157 consecutive patients with newly diagnosed HCC and 156 patients with liver cirrhosis (LC) as the control group. GPC3 plasma levels were measured using two commercially available enzyme-linked immunosorbent assays (ELISAs, named as Assay 1 and 2), and AFP levels were measured using an enzyme-linked chemiluminescent immunoassay. The diagnostic accuracy was analyzed using the receiver operating characteristics (ROC) curve. Results Plasma GPC3 levels in HCC patients were very low (0–3.09 ng/mL) in Assay 1, while only 3 of the 157 patients (1.9%) showed detectable GPC3 levels in Assay 2. The median GPC3 level was not significantly elevated in the HCC group (0.80 ng/mL) compared with the LC group (0.60 ng/mL). The area under the ROC curve (AUC) for GPC3 was 0.559 in Assay 1. In contrast, the median AFP level was significantly higher in HCC (27.72 ng/mL) than in LC (4.74 ng/mL), with an AUC of 0.729. Conclusion The plasma level of GPC3 is a poor diagnostic marker for HCC, being far inferior to AFP. The development of a consistent detection system for the blood level of GPC3 is warranted

Avoidant Restrictive Food Intake Disorder Prevalent Among Patients With Inflammatory Bowel Disease

Background & Aims Inflammatory bowel disease (IBD) patients alter their dietary behaviors to reduce disease-related symptoms, avoid feared food triggers, and control inflammation. This study aimed to estimate the prevalence of avoidant/restrictive food intake disorder (ARFID), evaluate risk factors, and examine the association with risk of malnutrition in patients with IBD. Methods This cross-sectional study recruited adult patients with IBD from an ambulatory clinic. ARFID risk was measured using the Nine-Item ARFID Screen. Nutritional risk was measured with the Patient Generated-Subjective Global Assessment. Logistic regression models were used to evaluate the association between clinical characteristics and a positive ARFID risk screen. Patient demographics, disease characteristics, and medical history were abstracted from medical records. Results Of the 161 participants (Crohn’s disease, 45.3%; ulcerative colitis, 51.6%; IBD-unclassified, 3.1%), 28 (17%) had a positive ARFID risk score (≥24). Most participants (92%) reported avoiding 1 or more foods while having active symptoms, and 74% continued to avoid 1 or more foods even in the absence of symptoms. Active symptoms (odds ratio, 5.35; 95% confidence interval, 1.91–15.01) and inflammation (odds ratio, 3.31; 95% confidence interval, 1.06–10.29) were significantly associated with positive ARFID risk. Patients with a positive ARFID risk screen were significantly more likely to be at risk for malnutrition (60.7% vs 15.8%; P \u3c .01). Conclusions Avoidant eating behaviors are common in IBD patients, even when in clinical remission. Patients who exhibit active symptoms and/or inflammation should be screened for ARFID risk, with referrals to registered dietitians to help monitor and address disordered eating behaviors and malnutrition risk

Macrotrabecular Massive, A Novel Hepatocellular Carcinoma Histological Subtype: Analysis Of Post- Resection And Transplant Recurrence

Macrotrabecular Massive (MTM-HCC) has been proposed as a new histological subtype of hepatocellular carcinoma (HCC). It has been previously shown to be associated with poorer clinical outcomes and aggressive tumor factors. This study aimed to further validate these findings by assessing the prognostic value of MT subtyping in post-resection and transplant patients. Review of 213 HCC cases from Yale New Haven Hospital showed 24 Macrotrabecular (MT-HCC) and 108 Conventional (CV-HCC) cases. Of these, 16 MT-HCC and 42 CV-HCC initial resection and transplant cases were identified. Clinical and pathologic features, recurrence, and overall survival data for these 58 cases were obtained. MT-HCC cases had higher recurrence, elevated alpha-fetoprotein levels, larger tumors, advanced Edmondson-Steiner nuclear grades and AJCC grades, and different etiological backgrounds compared to CV-HCC cases. Survival analysis revealed no significant difference in overall survival (p=0.165), with only recurrence as an independent risk factor (p=0.032). However, MT-HCC had poorer recurrence free survival (p=0.005), and MT-HCC (p=0.004) was a significant risk factor for recurrence. Overall, MT-HCC was associated with aggressive tumor characteristics and conferred a poorer recurrence free survival compared to CV-HCC cases independent of traditional poor prognostic markers such as vascular invasion. These results add to previous reports of MT-HCC characteristics, further suggesting that HCC showing MT pattern predominance may warrant closer follow-up post resection and transplantatio

A 77-Year-Old Woman With Capillary Hypoxia and Perioral Cyanosis

Case presentationA 77-year-old woman with asthma, hypothyroidism, irritable bowel syndrome, overactive bladder, and multiple rheumatologic conditions was sent from the clinic to the ED for evaluation of hypoxia. In the clinic, she reported dizziness without shortness of breath and was noted to have perioral cyanosis with an oxygen saturation measured by pulse oximetry (Spo2) of 80%. She was given a nonrebreather mask delivering oxygen at 8 L/min, but the Spo2 remained at 77% to 82%. In the ED, the patient reported intermittent shortness of breath, 2 to 3 days of mild left lower extremity swelling, and a brief episode of lightheadedness earlier in the day that had since resolved. She denied fevers/chills, upper respiratory symptoms, and chest pain. She had been referred to the pulmonology clinic 3 years earlier to evaluate mild hypoxia with Spo2 readings in the low 90% range, but pulmonary function testing failed to identify an etiology. There was no history of VTE. Her rheumatologic conditions included osteoarthritis, rheumatoid arthritis, Sjögren's syndrome, and fibromyalgia
