High Mortality With Non-O1/Non-O139 Vibrio cholera Bacteraemia in Patients With Cirrhosis.

Background: Data on non-O1/non-O139 Vibrio cholera (NOVC) infection in liver disease is limited. We studied the clinical features and outcome of patients with cirrhosis with non-NOVC bacteraemia and/or spontaneous bacterial peritonitis (SBP) when compared to non-extended spectrum beta lactamase (non-ESBL) Escherichia coli (E. coli). Methods: Hospital information system of patients with cirrhosis admitted with bacteraemia and/or SBP from 2010 to 2020 was searched to include patients with NOVC infection. Non-ESBL E. coli bacteraemia/bacterascites were chosen as a comparator group, matched for the date of admission within 5 days of index case. Propensity score matching (PSM) was done for patient's age and Child score to compare outcome at discharge between NOVC-infected and E. coli-infected cirrhotic patients. Results: There were 2545 patients admitted with bacteraemia and/or SBP during the study period; 29 had NOVC isolated (M:F = 23:6; age: 39, 18-54 years; median, range; model for end-stage liver disease [MELD] score: 25, 12-38; Child score: 11, 10-12.5) from either blood (26), ascites (3), or both (8). Of these, 26 isolates were pan-sensitive to antibiotic sensitivity tests. Fifty-three patients with non-ESBL E. coli were isolated (M: F = 43:10; age: 48; 18-69 years; MELD score: 25, 20-32; Child score:12,11-13) from blood (31), ascites (17), or both (5) within the selected time frame. Of these, 48 isolates were sensitive to the empirical antibiotics initiated.After PSM, in comparison with 29 non-ESBL E. coli patients (age: 41, 18-55 years; MELD score: 24, 19-31; Child score: 12, 11-13), NOVC patients had higher incidence of circulatory failure at admission (14 [49 %] vs 4 [13 %]; P: 0.01) and significantly higher in-hospital mortality (15 [52 %] vs 6 [20 %];P: 0.028]. Conclusions: Bacteraemia due to non-O1/non-O139 strains of V. cholera, is an uncommon cause of bacteraemia or bacterascites in patients with cirrhosis and is associated with high incidence of circulatory failure and significant mortality.

Centrifugal technique of plasma exchange and low-dose steroid to treat very severe alcoholic hepatitis patients: A retrospective analysis.

BACKGROUND: Low-volume plasma exchange (PLEX) and low-dose steroid improve survival in severe alcoholic hepatitis. We aimed to compare one-year survival of very severe alcoholic hepatitis (VSAH) patients treated with centrifugal PLEX (cPLEX), membrane PLEX (mPLEX) or standard medical treatment (SMT). METHODS: We retrospectively analyzed survival in consecutive VSAH patients treated at our department from November 2017 to September 2021. PLEX patients received low-volume PLEX along with low-dose steroid (tab. prednisolone 10 mg or 20 mg daily). To adjust for baseline differences between the three treatment (cPLEX, mPLEX or SMT) groups, propensity score (PS) matching was done. Acute-on-chronic liver failure (ACLF) was defined as per European Association for the Study of the Liver (EASL). The primary study outcome was one-year transplant-free survival of PS-matched VSAH patients treated with cPLEX compared to SMT. RESULTS: Of 101 PLEX-eligible VSAH patients, 30 patients were treated with cPLEX, 21 with mPLEX and 50 with SMT. On comparing 30 PS-matched patients each in the cPLEX group vs. the SMT group, transplant-free survival in the cPLEX group was 86.7% at one month, 70% at three months and 52.4% at one year and in the SMT group was 33.3% at one month, 23.3% at three months and 16.7% at one year with hazard ratio (HR [95% CI]) in favor of the cPLEX group (0.29 [0.15-0.56], p < 0.001). Total 21 patients each (PS-matched) in cPLEX and mPLEX groups were compared and one-year survival was better with cPLEX (0.33 [0.16-0.69], p = 0.001). The sub-group analysis of VSAH (PS-matched cohort) patients with ACLF also showed better survival with cPLEX compared to SMT (0.38 [0.17-0.83], p = 0.003) and compared to mPLEX (0.43 [0.17-0.95], p = 0.03). CONCLUSION: Better one-year transplant-free survival was noted among PS-matched VSAH patients treated with cPLEX (and low-dose steroid) compared to SMT (without steroid).

Single-Centre Experience With Low-Volume Plasma Exchange and Low-Dose Steroid to Treat Patients With Idiosyncratic Drug-Induced Acute Liver Failure.

Background: Idiosyncratic drug-induced liver injury (iDILI) causing acute liver failure (ALF) carries high short-term mortality and patients who meet King's College criteria for liver transplantation have 1-month survival of 34% without liver transplantation (PMID: 20949552). We present our experience with low-volume plasma exchange (PLEX-LV, 50% of estimated plasma volume exchanged per session) and low-dose steroid to treat iDILI ALF. Methods: We retrospectively analysed data of patients with iDILI (diagnosed as per RUCAM score), treated with PLEX-LV and low-dose steroid (prednisolone: 10 mg OD, with rapid taper) in our department from 2016 to 2022. Baseline and dynamic parameters (post-PLEX) were assessed as predictors of 1-month liver transplantation-free survival. Results: Twenty-two iDILI patients [probable: possible iDILI: 20:2, males: 9, age: 30 (14-84) years, median (range); MELD score: 30.5 (19-43)] underwent PLEX-LV for ALF during the study period. Causative agents were complementary and alternative medications (36%), antiepileptics (18%) antimicrobials (14%), antitubercular drugs (14%), antifungal drugs (9%) and others (9%). All patients had jaundice and encephalopathy; 9 patients also had ascites. None of the patients underwent liver transplantation. Study patients underwent 3 (1-7) PLEX sessions and 1.4 (0.6-1.6) litres of plasma was exchanged per session. One-month transplant-free survival was 59% (13/22) in the study population and 63% (12/19) among patients who fulfilled Kings College criteria for liver transplantation. Reduction of ≥25% in plasma von Willebrand factor (VWF) levels after PLEX-LV predicted improved survival (HR: 0.09, 95% CI: 0.01-0.65; AUROC: 0.81; 95% CI: 0.6-1.0). Conclusion: Low-volume PLEX and low-dose steroid appears a promising treatment option in patients with iDILI-induced ALF not opting for liver transplantation. Dynamic changes in VWF level after PLEX predict 1-month survival in these patients.

Caring for the Bone Health Among Liver Transplant Recipients.

Liver transplant outcomes have improved over the years, and currently, the quality of life and long-term well-being of these patients needs to be improved. Improving bone health goes a long way toward achieving this objective. Poor bone health (osteopenia and osteoporosis) although prevalent, is often overlooked owing to its asymptomatic nature. It can be complicated by debilitating fracture affecting quality of life. It is recommended to assess and optimize bone health prior to liver transplant. Multiple factors contribute to poor bone health in a liver transplant recipient and it is vital to understand and ameliorate these. A careful and targeted approach with inputs from multidisciplinary team involving transplant physician, endocrinologist, occupational therapist, nutritionist, and nursing personnel may often be required. In this review, we aim to concisely discuss the various aspects related to prevalence, pathophysiology, evaluation, treatment, and follow-up of bone disease among liver transplant recipients.

Low Volume Plasma Exchange and Low Dose Steroid Improve Survival in Patients With Alcohol-Related Acute on Chronic Liver Failure and Severe Alcoholic Hepatitis - Preliminary Experience.

Background: Alcohol-related acute on chronic liver failure (A-ACLF) patients have high short-term mortality and are poor candidates for steroid therapy. Plasma exchange (PLEX) improves survival in ACLF patients. We analyzed our experience with low volume PLEX (50% of plasma volume exchanged per session) and low dose steroids to treat A-ACLF patients. Methods: We retrospectively compared the efficacy of low volume PLEX and low-dose steroids with standard medical treatment (SMT) in A-ACLF patients treated at our center between November 2017 to June 2019. The primary study outcome was one-year survival. Results: Twenty-one A-ACLF patients in PLEX group [age 40 (29-56) years, median (range); MELD score 31 (29-46)] and 29 A-ACLF patients in SMT group [age 41.5 (28-63) years, MELD score 37 (21-48)] were studied. All 50 study patients had severe alcoholic hepatitis [mDF 84.7 (50-389)]. PLEX group patients had 3 (1-7) PLEX sessions with 1.5 (1.4-1.6) liters of plasma exchanged per session and oral Prednisolone 20 mg daily, tapered over 1 month. Kaplan Meier analysis showed better survival over 1 year in the PLEX group compared to the SMT group (P = 0.03). There was renal dysfunction in 10 patients in the PLEX group, which normalized in six patients after PLEX. Conclusion: In this preliminary report, compared to SMT, low volume PLEX and low dose steroid improved survival over one year in A-ACLF patients with severe alcoholic hepatitis. In patients with renal dysfunction, 60% showed improvement in renal function with PLEX. Studies with a larger number of patients are needed to validate these results.

Plasma Von Willebrand Factor Levels Predict Survival in COVID-19 Patients Across the Entire Spectrum of Disease Severity.

BACKGROUND: Characterization of reticulo-endothelial activation in COVID-19 may guide treatment. OBJECTIVES: To assess reticulo-endothelial activation and its correlation with disease severity and death in patients across the entire spectrum of COVID-19 severity. METHODS: Consecutive hospitalized COVID-19 patients were studied, with similar number of patients in each disease severity category. Baseline serum ferritin, sCD163 (macrophage activation markers) and plasma von Willebrand factor (VWF) antigen (endothelial activation marker) levels were studied. Clinical parameters and plasma D-dimer levels were also studied. The study parameters were correlated with COVID-19 severity and survival. RESULTS: The 143 patients (104 males [80%], age 54 [42 - 65] years, median [inter-quartile range]) presented 4 (3-7) days after symptom onset. Thirty-four patients had mild disease, 36 had moderate disease, 36 had severe disease and 37 had critical disease at baseline. With increasing COVID-19 severity, ferritin, sCD163, VWF and D-dimer levels significantly increased at baseline, however, 139 patients had normal sCD163 levels. Of the reticulo-endothelial markers, VWF level independently correlated with COVID-19 severity and with survival. VWF level > 332.6 units/dl correlated with COVID-19 severity (odds ratio [OR]: 2.77 [95% confidence interval (C.I): 1.1 - 6.99], p value: 0.031) and in-hospital death (OR [95% CI]: 29.28 [5.2 - 165], p value < 0.001). CONCLUSIONS: Reticulo-endothelial activation markers increased incrementally with worsening COVID-19 severity. Baseline endothelial activation marker (VWF), and not macrophage activation markers, independently correlated with COVID-19 severity and death.
