These results indicated that patients with hepatitis B liver cirrhosis have a disturbed sleep, which might be an MHE symptom, further causing considerable anxiety. Thus, the evaluation of sleep quality and psychological state of patients with hepatitis B liver cirrhosis necessitates further investigation to guide positive intervention.

Esophageal motility disorders are prevalent in 90% of patients with systemic sclerosis [scleroderma (SSc)], with an increased mortality rate in patients with severe esophageal involvement. Esophageal smooth muscle damage caused by ischemia, nerve damage, and inflammatory factors may be responsible for discomfort and various complications in these patients. The clinical manifestations are diverse. Most hospitals still use traditional esophageal manometry and 24-h pH monitoring to diagnose esophageal function in patients with SSc. The aim of this review article is to provide an overview of SSc-related esophageal motility disorders and related research progress, including the pathogenesis and clinical features of these disorders and the progress made in endoscopic diagnosis. We also discuss the possible pathogenesis and potential therapeutic targets.

This article is aim to investigate the safety and immunogenicity of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine booster in patients with chronic liver disease（CLD）. A total of 114 patients with CLD who received a SARS-CoV-2 vaccine booster were enrolled in this study. Serum samples were collected from enrolled patients at least 14 days after the booster dose and tested for SARS-CoV-2 neutralizing antibody (novel coronavirus neutralizing antibody, nCoV NTAb) and IgG antibody against SARS-CoV-2 spike binding domain（novel coronavirus spike receptor-binding domain antibody，nCoV S-RBD antibody）levels. The positive rates of nCoV NTAb and nCoV S-RBD in patients with CLD were 87.72% and 91.23%, respectively, after the booster injection of coronavirus disease 2019 (COVID-19) vaccine. The booster injection resulted in the production of nCov NTAb in 66.7% of patients and nCov-SRBD antibody in 71.43% of patients with CLD who failed basic immunization. After basic SARS-CoV-2 immunization, the booster SARS-CoV2 vaccine increased the serum conversion rate and the level of nCov NTAb and nCov-SRBD antibodies in patients with CLD (including patients with cirrhosis). The severity of the liver disease is related to the immune response to COVID-19 vaccine.

Aim: The present study discussed the humoral immune response and antibody dynamics after primary and booster immunity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines among patients with chronic liver disease (CLD) in the real world. Thus, it provided data to develop SARS-CoV-2 vaccination strategy. Methods: Patients with confirmed CLD and completed primary or booster immunity of SARS-CoV-2 vaccines were enrolled. Serological specimens were collected after primary or booster immunity of SARS-CoV-2 vaccines to detect novel coronavirus neutralizing antibody (nCoV NTAb) and novel coronavirus spike receptor-binding domain antibody (nCoV S-RBD). Thus, we could evaluate the humoral immune response and antibody dynamics after primary and booster immunity of SARS-CoV-2 vaccines among patients with CLD. Simultaneously, baseline demographics, liver disease-related situations, comorbidity-related situations, SARS-CoV-2 vaccination information, and laboratory examination-related indicators of patients were collected. Results: A total of 315 patients received SARS-CoV-2 vaccines, including 223 patients who completed the primary immunity of SARS-CoV-2 vaccines, 114 patients who completed booster immunity of SARS-CoV-2 vaccines, and 22 patients who underwent the antibody detection of SARS-CoV-2 vaccines after both primary and booster immunities. The positive rate of nCoV NTAb was 59.64% in Primary and 87.72% in Booster (P<0.001). The median level of nCoV NTAb was 11.53 AU/mL in Primary and 31.98 AU/mL in Booster (P<0.001). The positive rate of nCoV S-RBD was 69.06% in Primary and 91.23% in Booster (P<0.001). The median level of nCoV S-RBD was 21.60AU/mL in Primary and 112.65 AU/mL in Booster (P<0.001). After booster immunity of SARS-CoV-2 vaccines in 22 patients, the positive rate of nCoV NTAb increased from 59.09% to 86.36%, and that of nCoV S-RBD increased from 68.18% to 90.91%. The median level of nCoV NTAb increased from 11.24 AU /mL to 59.14 AU /mL after booster immunity. The median level of nCoV S-RBD increased from 27.28 AU/mL to 219.10 AU/mL. Compared to the antibody level of primary immunity, the median level of nCoV NTAb and nCoV S-RBD in 22 patients was increased by 5.26 and 8.03 times, respectively. Among 22 patients, 9 were negative for nCoV NTAb after primary immunity, while 6 were transformed positive after booster immunity, and the positive conversion rate of nCoV NTAb was 66.7%. On the other hand, 7 patients were negative for nCoV S-RBD after primary immunity, while 5 were transformed positive after booster immunity, and the positive conversion rate of nCoV S-RBD was 71.4%. Conclusion: Patients with CLD show improved humoral immune response after completing primary and booster immunity of SARS-CoV-2 vaccines, while booster immunity further improves the positive rate and antibody level of patients with CLD. Finally, the positive conversion rate among patients with primary immunity failure also can be improved after booster immunity.

AimThe present study aimed to evaluate the durability of immune response after basic and booster immunization with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines in patients with chronic liver disease (CLD).MethodsPatients with CLD and complete basic or booster immunization with SARS-CoV-2 vaccines were included in this study. Based on the vaccination situation, they were divided into the basic immunity group (Basic) and the booster immunity group (Booster), which were then subdivided into four groups according to the time interval from completion of basic immunization or booster immunization to serological specimen collection. The positive rates and antibody titers of novel coronavirus neutralizing antibody (nCoV NTAb) and novel coronavirus spike receptor-binding domain antibody (nCoV S-RBD) were analyzed.ResultsA total of 313 patients with CLD were enrolled in this study, including 201 in Basic and 112 in Booster. The positive rates of nCoV NTAb and nCoV S-RBD within 30 days of completing basic immunization were 80.4% and 84.8%, respectively, but decreased rapidly with the extension of vaccination time, and only 29% and 48.4% of patients with CLD remained positive for nCoV NTAb and nCoV S-RBD, respectively, after 120 days of completing basic immunization. Within 30 days of booster immunization, the positive rates of nCoV NTAb and nCoV S-RBD in patients with CLD rapidly increased from 29.0% and 48.4% at the end of basic immunization to 95.2% and 90.5%, and maintained a high level (defined as the positive rate &gt;50%) until 120 days when the positive rates of nCoV NTAb and nCoV S-RBD were still high at 79.5% and 87.2%, respectively. After basic immunization, the time for nCoV NTAb and nCoV S-RBD to turn negative was 120 and 169 days, respectively, and the negative time of nCoV NTAb and nCoV S-RBD was significantly prolonged to 266 days and 329 days, respectively.ConclusionIt is safe and effective for patients with CLD to complete basic and booster immunization with SARS-CoV-2 vaccines. After booster immunization, the immune response of patients with CLD was further improved and the durability of the SARS-CoV-2 antibody was significantly prolonged.
