ABSTRACT
Background and aims: Solid organ transplant recipients (SOTRs) have been considered as an extremely vulnerable population in respect to SARS-CoV-2 infection. We aimed to assess the incidence and lethality rate of SARS-CoV-2 infection in different organ transplant settings using the liver as a comparator. Methods: In this nationwide population-based study we compared the crude incidence and lethality rates of SARS-CoV-2 infection [95% Bonferroni adjusted CI (Ba-CI)] among Italian LTRs as compared to non-liver SOTRs and to general population. The following independent groups had been compared: Italian general population, all SOTRs, liver transplant recipients (LTRs) and non-Liver SOTRs in area with different incidence of infection. Incidence rate ratio (IRR) and lethality rate ratio (LRR) was assessed. Community risk exposures in transplant settings were assessed. Results: From February 21 to June 22, 2020, there were 450 cases of SARS-CoV-2 infections over 14168 LTRs (n=89) and 29815 non-liver SOTRs (n= 361). A significantly lower risk of infection [IRR 0.56 (Ba-CI 0.34-0.92), 0.45 (Ba-CI 0.26-0.79), 0.52 (Ba-CI 0.36-0.75)] and a lower lethality rate ratio [(LRR 0.61 (Ba-CI 0.23-1.57), 0.37 (0.08-1.76), 0.52 (0.23-1.18] was found among LTRs as compared to non-liver SOTRs in the three areas. Excluding Lombardy, the risk of infection and lethality in LTRs was lower compared to general population. Non-Liver SOTRs showed an increased risk of infection and lethality at all geographic levels compared to general population. No significant difference in the adherence to mitigation policies was found. Conclusions: Liver transplantation was associated with a significantly lower risk of SARS-CoV-2 infection and lethality in respect to non-liver solid organ transplants. A separate evaluation of organ-specific risk stratification analysis and vaccination responses in transplant population is needed.
ABSTRACT
Background and aim: Access to liver transplantation (LT) can beaffected by several barriers resulting in delayed referral and increased risk of mortality. Therefore, hub-and-spoke networks have been implemented in order to manage patients with liver disease. COVID-19 pandemic may have significantly changed this scenario, as most of medical resources have been allocated for the care of patients with SARS-CoV-2 infection. This study aimed to assess the influence of COVID-19 pandemic on referrals of patients with liver disease to a LT Center.Materials and methods: An integrated referral program was developed since 10.2017 at Multivisceral Transplant Unit, PadovaUniversity. All consecutive adult patients with liver disease referred for the first time using this program from 10.2017 to 12.2020 were prospectively collected. Clinical characteristics were analyzedoverall and according to era of referral (pre-COVID-19 era:10.2017-02.2020;COVID-19 era:03.2020-12.2020).Results: 231 patients with liver disease were referred over the study period (men 61%, mean ± SD age: 54±10 years). End-stage liver disease was the most common underlying condition (78.3%), followed by acute liver injury/acute liver failure (17.3%). During COVID-19 pandemic, the rate of referred patients showed a stable trend, if compared with the previous period (5.1 patients/monthvs. 6.1 patients/month), also when only in-patient referrals wereconsidered (pre-COVID-19 era vs.COVID-19 era: 2.9 vs. 3.2 patients/month). Considering 181 patients with cirrhosis, underlying etiology (p=0.22), severity of liver disease (MELD score: 21±7 vs. 20±8;p=0.44), and inpatient referrals (42% vs. 51%;p=0.34) did not differ between pre-COVID-19 and COVID-19 eras. There was a decreasing rate of ICU admission for cirrhosis-related complicationsduring COVID-19 pandemic (22% vs. 34%;p=0.3), with an increased in-hospital transplant-free mortality (41% vs. 30%;p=0.3).Conclusions: Conclusion: Our results did not show a significant decrease in the number of referrals and type of indications during the COVID-19 pandemic;however, the in-hospital transplant free mortality showed an increasing trend, which could be the consequence of a decreasing rate of ICU admissions. Taken together, thesefactors confirmed the importance of a referral network for the care of patients with liver disease, but also how the COVID-19 pandemic may influence the short-term outcome of patients with liver disease.
ABSTRACT
Aims This is a prospective observational web-based survey aimed to assess the impact of SARS-CoV-2 pandemic onGastroenterology Units in Italy. Methods All members of the Italian Society of Gastroenterology (SIGE) were invited to answer a 39-point multiple-choiceweb-based survey between March 30 thand April 7 th2020. Results Data of 121 hospitals from all 20 Italian regions were analyzed. Overall, 10.7 % of Gastroenterology divisions havebeen converted to COVID Units. Outpatients consultations, endoscopic and ultrasound procedures were limited to urgenciesand oncology indications in 85.1 %, 96.2 % and 72.2 % of Units, respectively, and 46.7 % of Units suspended the screeningfor colorectal cancer.In order to guarantee the ordinary follow-up of outpatients, 83/121 (68.6 %) divisions activated aremote consultancy service (63.9 % by phone, 31.3 % by email, 4.8 % by video). Overall, 112/121 (92.6 %) GI Units issued and followed a specific protocol for the management of patients with suspectedor confirmed SARS-CoV-2 infection. The 72.2 % of the staff received proper training for the use of personal protective equipment, although 45.5 % did not havesufficient devices for an adequate replacement. With regard to PPE availability, N95/FFP2-3 masks were available in 91/121 (75.2 %), surgical masks in 115/121 (95.0 %),gloves in 117/121 (96.7 %), disposable gown in 100/121 (82.6 %), hairnet in 104/121 (85.9 %), goggles in 78/121 (64.5 %)and boots in 57/121 (47.1 %) of divisions. Finally, in 41/121 GI divisions (33.9 %) there was at least one healthcare professional who got infected, in a total of 132subjects, of which 121/132 from divisions not-converted to COVID Units and 75/132 from high-prevalence areas. Conclusions Substantial changes of practice and reduction of procedures have been recorded in the entire country duringthe first wave of the pandemic. The long-term impact of such modifications is difficult to estimate but potentially very riskyfor many digestive diseases.
