Common variable immunodeficiency enteropathy is a sprue-like disease, which may manifest as a severe malabsorption syndrome with nutritional deficits and cachexia. The authors report a case of a 33-year-old Afghan man, who presented to the emergency department due to chronic watery diarrhea and severe malnourishment. He had been previously misdiagnosed with celiac disease in his early adulthood; however, this was based on inconclusive findings. After a thorough diagnostic workup, the final diagnosis of common variable immunodeficiency enteropathy with symptomatic norovirus infection of the gut was obtained during his prolonged hospitalization. A slow but progressive improvement was observed with immunoglobulin replacement therapy, corticotherapy, and ribavirin treatment. This is a noteworthy case of a rare malabsorption disorder, and it reviews important aspects concerning the differential diagnosis of small bowel villous atrophy of unknown etiology, as well as gastrointestinal manifestations of common variable immunodeficiency disorder.

Liver cancer is globally the third leading cause of death from cancer. Hepatocellular carcinoma (HCC) develops in patients with underlying liver disease. The fraction of HCC attributed to nonalcoholic fatty liver disease (NAFLD) shows an accelerated increase in the last decades, being already responsible for 15% of all HCC cases. Similar to other causes of liver cirrhosis, patients with NAFLD-associated cirrhosis should be enrolled in HCC-screening programs, yet these patients are under-screened, and currently are less than half likely to be proposed for HCC screening as compared to patients with HCV-associated cirrhosis. NAFLD-associated HCC has the peculiarity of occurring in precirrhotic phases in 20-50% of the cases. Currently, HCC screening in precirrhotic NAFLD patients is not routinely recommended, since the risk of developing HCC is very low. However, because NAFLD affects one-third of the worldwide population, noncirrhotic NAFLD already accounts for 6% of HCC cases. As such, it is pressing to develop stratification tools, in order to personalize the individual risk of HCC development in a patient with NAFLD, allowing precision HCC-screening programs. This review summarizes the epidemiology of NAFLD-associated HCC with a critical analysis of current HCC-screening recommendations.

Gastrointestinal tuberculosis is an uncommon entity, in which clinical presentation can be widely variable, from mild and nonspecific symptoms to an acute abdomen and gastrointestinal bleeding. Gastric involvement by Mycobacterium tuberculosis is rare, especially when it occurs without other recognized infectious foci - primary gastric tuberculosis - with only a few reported cases. Endoscopic findings can be very heterogeneous, from areas of hyperemia to pseudotumor lesions. We present a case of primary gastric tuberculosis in an immunocompetent patient, in which the absence of an epidemiological context and nonspecific endoscopic findings led to a delay in the diagnosis. Bite-on-bite biopsies proved to be essential, allowing to obtain samples from deeper layers of the submucosa where M. tuberculosis was identified. This case aimed to increase awareness for this entity, especially in endemic countries or regions with a high prevalence of tuberculosis since the diagnosis is based mainly on a high index of suspicion.

Background and objectives: Endoscopic band ligation (EBL) plays a critical role in patients with clinically significant portal hypertension, as variceal eradication (VE) is essential to prevent further variceal upper gastrointestinal bleeding (GI). The emergence of COVID-19 has led to a dramatic reduction in endoscopic activity. Our study aimed to evaluate the effect of COVID-19 on VE, GI, and 6-month mortality of patients treated with prophylactic EBL therapy. In addition, our goal was to identify the risk factors for our proposed outcomes.

Methods: A single-center retrospective cohort study included patients with esophageal varices treated with prophylactic EBL therapy between 2017 and 2021. To demonstrate the impact of COVID-19 on two independent groups on prophylactic EBL therapy with 1 year of follow-up, March 2019 was selected as the cut-off date. Clinical, laboratory, and endoscopic data were recovered from electronic reports.

Results: Ninety-seven patients underwent 398 prophylactic EBL sessions, 75 men (77.3%) with mean age 59 ± 12 years. Most achieved VE (60.8%), 14.4% had GI bleeding post-therapy, and 15.5% died at 6 months. The rate of variceal obliteration was significantly lower in the pandemic group (40.9% vs. 77.4% in the pre-pandemic group, p = 0.001). Mean number of EBL sessions and pandemic group were independently associated with incomplete VE, while MELD-Na, portal vein thrombosis and failed VE were identified as risk factors associated with mortality at 6 months.

Conclusions: Almost 60% of patients in the pandemic group failed to eradicate esophageal varices. Failure to achieve this result conferred a higher risk of GI bleeding and death at 6 months, the latter also significantly associated with the MELD-Na score and portal vein thrombosis. Our study is among the first to demonstrate the impact of COVID-19 in patients receiving prophylactic EBL therapy.

Introduction: The outbreak of coronavirus disease 2019 (COVID-19) had affected clinical practice in several ways, including the restriction of nonessential endoscopic procedures. Therefore, our aim was to evaluate how colorectal cancer (CRC) diagnosis and management was affected during the first year of pandemics in Portugal.

Methods: This is a Portuguese substudy of the French retrospective multicentric study ETICC (Etude de l'Impact de la pandémie COVID-19 sur le diagnostic et la prise en charge du Cancer Colorectal). We compared patients' characteristics, clinical manifestations, CRC staging at diagnosis, delay to first medical appointment, histological diagnosis, surgical and medical treatments between the year previous to the pandemics (control) and the first year of pandemics.

Results: We included 766 patients: 496 in the control group and 270 in the COVID group. There was no significant difference in CRC staging at diagnosis between both groups, with 21% being diagnosed as metastatic in the control group and 22% in the first year of pandemics (p = 0.770). Contrary to what happened in France, there was a significant decrease in CRC diagnosis in asymptomatic patients (25-8.4%; p < 0.001) and after a positive fecal immunochemical test (20.8-11.3%; p = 0.002) during the pandemics. Although the increase in the overall complication rate at diagnosis was nonsignificant, in Portugal, there was a significant increase in diagnosis of abdominal occlusion (12.1-18.1%; p = 0.033). In Portugal, time between the beginning of symptoms and the first medical appointment significantly increased from a median of 50 days to 64 days during COVID (p < 0.001). On the contrary, time between histological diagnosis and tumor resection had significantly decreased from a median of 65 to 39 days (p < 0.001). Time between histological diagnosis and neoadjuvant treatment was not statistically different (median of 64-67 days; p = 0.590), as was time between histological diagnosis and palliative chemotherapy (median of 50-51 days; p = 1.000). Time from CRC resection and adjuvant treatment has significantly decreased from a median of 54 to 43 days (p = 0.001).

Discussion: We found a significant impact in CRC diagnosis in the first year of pandemics, more pronounced than what was found in France. These are likely related not only with the closing of endoscopy units but also with the difficulties patients had in finding an appointment with their general practitioners. On the other hand, both in France and Portugal, the first year of pandemics did not worsen CRC staging at diagnosis and did not significantly affect medical and surgical treatments once the diagnosis was made.
