The pandemic of coronavirus disease 2019 (COVID-19), caused by a newly identified β-coronavirus (SARS-CoV-2) has emerged as a dire health problem, causing a massive crisis for global health. Primary method of transmission was firstly thought to be animal to human transmission. However, it has been observed that the virus is transmitted from human to human via respiratory droplets. Interestingly, SARS-CoV-2 ribonucleic acid (RNA) has been isolated from patient stools, suggesting a possible gastrointestinal (GI) involvement. Most commonly reported clinical manifestations are fever, fatigue and dry cough. Interestingly, a small percentage of patients experience GI symptoms with the most common being anorexia, diarrhea, nausea and vomiting. The presence of viral RNA in stools is also common and fecal tests can be positive even after negative respiratory samples. The exact incidence of digestive symptoms is a matter of debate. The distribution of Angiotensin converting enzyme type 2 receptors in multiple organs in the body provides a possible explanation for the digestive symptoms’ mechanism. Cases with solely GI symptoms have been reported in both adults and children. Viral RNA has also been detected in stool and blood samples, indicating the possibility of liver damage, which has been reported in COVID-19 patients. The presence of chronic liver disease appears to be a risk factor for severe complications and a poorer prognosis, however data from these cases is lacking. The aim of this review is firstly, to briefly update what is known about the origin and the transmission of SARS-CoV-2, but mainly to focus on the manifestations of the GI tract and their pathophysiological background, so that physicians on the one hand, not to underestimate or disregard digestive symptoms due to the small number of patients exhibiting exclusively this symptomatology and on the other, to have SARS-CoV-2 on their mind when the “gastroenteritis” type symptoms predominate.
Metastatic lesions of the colon are a rare clinical entity that may present difficulties in management. The incidence of these metastases appears to be increasing, as a result of physicians’ greater awareness during follow-up investigations of a primary neoplasm. Furthermore, the presence of a greater proportion of these abnormalities at autopsy should be a triggering factor for further investigation for doctors dealing with colorectal oncology. Their clinical presentation may vary from asymptomatic to signs similar to those of colorectal cancer. However, immunohistological analysis is considered the cornerstone for differentiating metastases to the colon, originating from other primaries, from primary colorectal neoplasms. Survival reports and treatment options vary. This article concisely presents the main characteristics of the secondary lesions to the colon from neoplasms that metastasize to the large intestine (namely, lung, ovary, breast, prostate, kidney, and melanoma) focusing on their incidence, their clinical presentation and the workup investigation. Physicians aware of this uncommon entity are much better prepared to apply an efficient diagnosis and workup, as well as an appropriate treatment strategy.
Background and aims IBD can impair the patients` functional capacity with significant negative effects on their quality of life. Our aim was to determine the impact of IBD diagnosis on fitness levels and to assess the levels of engagement in physical activity and fatigue in IBD patients` pre-and post-diagnosis. Methods A prospective multi-centre cross-sectional study was performed. Patients diagnosed with IBD in the previous 18 months were recruited. Inclusion criteria included clinical remission and/or no treatment changes within the previous 6 months. Physical exercise levels were assessed by the Godin score and fatigue levels was assessed by the Functional assessment of chronic illness therapy (FACIT) score. Results 158 patients (100 CD) were recruited. Mean age was 35.1 years (95% CI ±2.0). Gender distribution was approximately equal (51.3% male). The Mean Harvey Bradshaw and Simple Clinical Colitis Activity indices were 2.25 (95% CI ±0.40) and 1.64 (95% CI ±0.49). Mean Godin score difference before and after IBD diagnosis was 6.94 (p = 0.002). Patients with UC (41.8%) were more likely than patients with CD (23.0%) to reduce their exercise levels (p=0.04). FACIT scores were lower in patients who had experienced relapses (p=0.012) and had severe disease (p=0.011). Approximately 1/3 of patients had a reduction in their activity level post-IBD diagnosis. Conclusions Patients were significantly less physically active after a diagnosis of IBD and this was more apparent in UC. Identification of risk factors associated with loss of fitness levels would help address the reduced patients` quality of life.

Background After the first case of infection with the novel coronavirus, SARS-CoV-2, in China, an outbreak rapidly spread, finally evolving into a global pandemic. The new disease was named coronavirus disease 2019 (COVID-19) and by May 10, 2020, it has affected more than 4 million people worldwide and caused more than 270,000 deaths. Methods We describe the Greek experience regarding the response to COVID-19, with particular focus on 2 COVID-19 reference hospitals in the metropolitan area of Athens, the capital of Greece. Results The first case of SARS-CoV-2 infection in Greece was reported on February 26, 2020, and prompted a decisive response from the Greek government. The primary focus was containment of virus spread, considering shortage of ICU beds. A general lockdown was implemented early on, and the national Health Care System underwent massive re-structuring. Our 2 gastrointestinal (GI) centers, which provide care for more than 1500 inflammatory bowel disease (IBD) patients, are located in hospitals that were transformed to COVID-19 reference centers. To maintain sufficient care for our patients, while also contributing to the fight against COVID-19, we undertook specific measures. These included provision of telemedicine services, electronic prescriptions and home delivery of medications, isolation of infusion units and IBD clinics in COVID-free zones of the hospitals, in addition to limiting endoscopies to emergencies only. Such practices allowed us to avoid interruption of appropriate therapies for IBD patients. In fact, within the SECURE-IBD database, there have been only 4 Greek IBD patients, to date, who have been reported as positive for SARS-CoV-2. Conclusion Timely application of preventive measures and strict compliance to guidelines limited the spread of COVID-19 in Greece and minimally impacted our IBD community, without interfering with therapeutic management.
