Background: There is an increasing number of reports on the presentation of gastrointestinal symptoms in cases of COVID-19.

Aim: To review the studies reporting gastrointestinal symptoms in COVID-19.

Results: Fifteen articles (2,800 patients) were identified. Gastrointestinal symptom frequency varied from 3.0% to 39.6% and included diarrhea (7.5%), náusea (4.5%), anorexia (4.4%), vomiting (1.3%), abdominal pain (0.5%), and belching/reflux (0.3%). Those symptoms can be the first manifestation of COVID-19, but whether they reflect a better or worse prognosis, is controversial. The potential relation of the angiotensin converting enzyme 2 receptor in the digestive tract as an entry route for the virus is discussed.

Conclusion: Gastrointestinal symptoms may be common in COVID-19, in some cases appearing as the first manifestation, even before fever and respiratory symptoms. Therefore, clinicians and gastroenterologists must be aware of those atypical cases during the current pandemic, as well as of the fecal-oral route and corresponding preventive measures.

Immune checkpoint inhibitors (ICIs), such as pembrolizumab, have revolutionized cancer therapy but can lead to severe immune-related adverse events (irAEs). We present a case of fulminant type 1 diabetes mellitus (T1DM) with diabetic ketoacidosis (DKA) and mesenteric ischemia in a 78-year-old woman with recurrent stage IIIC1 cervical cancer treated with pembrolizumab. Thirty-four days after initiating a pembrolizumab-containing regimen, she presented with vomiting, severe hyperglycemia, metabolic acidosis, and strongly positive urine ketones.

Purpose//objectives: A disproportionate incidence's increase of rectal cancer in patients younger than 50 years of age. The ESMO and NCCN recommendations are not age-specific and the literature is poor and conflicting. We decided to examine patients with rectal cancer treated in our centre in the last 15 years with curative neoadjuvant radiochemotherapy comparing outcomes in the two groups under and over 55 years old.
