Abstract
BACKGROUND To date, there's no evidence of an increased risk of SARS-CoV-2 infection or more severe COVID-19 in patients with inflammatory bowel disease (IBD). However, whether COVID-19 alters the clinical course of IBD or whether IBD treatment affects the immunological response to SARS-CoV-2 is still under investigation, especially in children. AIM To assess the serological response to SARS-CoV-2 in children with IBD, and to evaluate the impact of COVID-19 on the clinical course of IBD. MATERIAL AND METHODS This prospective study enrolled children (0-18 years) followed-up at the University Hospital of Padova for IBD, who acquired a confirmed SARS-CoV-2 infection between 02.2020 and 02.2021. The anti-SARS-CoV-2 S-RBD IgG titer was evaluated at 3 months after infection and compared to that of a control group of healthy children matched for age, sex, and COVID-19 severity. RESULTS Twelve children with IBD (M = 5; median age 14 years) contracted COVID-19 during the study period. 11/12 patients were under immunomodulatory treatment (4/12 steroids; 6/12 azathioprine; 3/12 anti-TNFs; 2 vedolizumab; 1 ustekinumab). SARS-CoV-2 infection remained asymptomatic in 4/12 children and caused mild COVID-19 in the remaining 8. Mean anti-SARS-CoV-2 IgG S-RBD titer was similar between IBD patients and controls (27.3 ± 43.8 vs. 36.8 ± 35.3 kAU/L, p = ns). No children experienced IBD flares nor required gastroenterological support during the infection period. DISCUSSION Children with IBD can mount a protective humoral response against SARS-CoV-2, which is comparable to that of their healthy peers regardless of ongoing immunomodulatory treatment. This study also supports the favorable course of PIBD during COVID-19 and vice-versa.

Abstract
Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) was first identified as a novel coronavirus in Wuhan, Hubei province, central China, in December 2019, and is responsible for the 2019-to-present pandemic. According to the most recent data released by the World Health Organization, more than 200 million people have been infected by SARS-CoV-2 so far, and more than 4 million people died worldwide. Although our knowledge on SARS-CoV-2 and COVID-19 is constantly growing, data on COVID-19 in immunocompromised patients are still limited. The aim of the present systematic review is to describe clinical picture, disease severity, proposed treatment regimen, and response to vaccination in patients with different types and severity of immunosuppression.

Abstract
Coronavirus disease 2019 (COVID-19) is a worldwide emergency that has affected millions of populations in developed and underdeveloped countries. To our surprise, many people have been tested positive twice. Few cases of true reinfections involved genetic alterations in the virus. Appearance of multiple positive tests may be due to human errors or remnant genetic material, but genetic modification in virus represents very serious issue of controlling this pandemic. It is the need of the day that all the gaps and deficiencies, represented by variable response of adaptive immune system toward this infection, be filled and rectified. We have discussed reinfections with variable outcomes along with the possible reasons for variable response. Phenomena such as T cell memory, absence of cross-reactive immunity, T cell exhaustion, drawbacks pertaining to neutralizing antibodies, and immune enhancement are crucial areas by which adaptive immune response can weaken considerably. Earlier and stronger herd immunity is also at the mercy of strong adaptive immune system to avoid future pandemics by the same microorganism. Likewise, consequences of this phenomenon should also be considered during vaccine development as resources worth billions are being used and staked. Many countries have entered the second/third waves of COVID-19. Therefore, we need to come up with ways toward uniform strengthening of adaptive immune response to fight off this pandemic. Also, to develop and maintain constant resistance to severe acute respiratory syndrome coronavirus (SARS-CoV-2), the mentioned weakened links in the chain of adaptive immunity may be explored to keep viral invasion and physiological damage to minimum.
