Liver injury in the HIV-positive population has been classically associated with hepatitis B or C viruses (HBV and HCV). While HBV or HCV co-infections have represented "Pillars of Hercules" for ...hepatic disease (not further beyond), it is now time to move forward and shed light on liver disease in HIV-infected patients without HBV or HCV co-infections. Indeed, over the last years, liver disease in HIV-mono-infected patients has emerged and fated to become one of the main non AIDS-related complications. Although several cases have specific etiologies (e.g., alcohol abuse), other cases are most challenging for the clinicians because the actual causes are only hypothesized, such as it is difficult to treat them appropriately. This new clinical entity has been named "cryptogenic" liver disease; it is polymorphic (e.g., hepatic steatosis, nodular regenerative hyperplasia or noncirrhotic portal hypertension) and multifactorial in nature, but HIV per se may play a key role. In this paper, we present a critical review of the relevant literature data, focusing on practical implications (including diagnostic tools and differential diagnosis), and delineate priorities for future research on this important topic.
Background. There is lack of data on the incidence of liver fibrosis (LF) progression in patients with human immunodeficiency virus (HIV) monoinfection and risk factors for LF. Methods. We performed ...an observational prospective study in a cohort of HIV-infected patients who had initiated highly active antiretroviral therapy (HAART). FIB-4 and aspartate aminotransferase (AST)-to-platelet ratio index (APRI) were assessed. The concordance between the 2 scores was assessed by weighted kappa coefficient. Kaplan-Meier analysis was used to estimate the incidence of LF. Cox regression analysis was used to assess the predictors of transition. Results. A total of 1112 patients were observed for a mean of 2249 days of follow-up. The concordance between FIB-4 and APRI was moderate (kappa =.573). The incidence of transition to higher FIB-4 classes was 0.064 (95% confidence interval CI, 0.056-0.072) per person-year of follow-up (PYFU), whereas the incidence of transition to higher APRI classes was 0.099 (95% CI, 0.089-0.110) per PYFU. The incidence of transition to FIB-4 >3.25 was 0.013 per PYFU (95% CI, 0.010-0.017) and 0.018 per PYFU (95% CI, 0.014-0.022) for APRI >1.5. In multivariate analyses, for transition to higher classes, HIV RNA level <500 copies/mL was found to be protective for both scores, and higher CD4+ T cell count was found to be protective for FIB-4. Additional risk factors were age ≥40 years, male sex, intravenous drug use as an HIV infection risk factor, higher degree of LF, higher gamma-glutamyl transpeptidase (γGT) at baseline, and use of dideoxynucleoside-analogue drugs (DDX). Consistent results for the main study outcomes were obtained for confirmed LF transition and transition to FIB-4 >3.25 and APRI>1.5 as study outcomes. Conclusions. Overall, our results suggest a possible benefit associated with earlier HAART initiation, provided that the effectiveness of HAART is sustained and treatment with DDX is avoided.
•Colchicine is not superior to standard of care in reducing the risk of mortality, clinical worsening or mechanical ventilation in hospitalized patients with COVID-19 pneumonia.•Colchicine should be ...administered with caution in the advanced phases of the disease.•Older patients with comorbidities (pre-existent heart, lung, upper-gastrointestinal, lower-gastrointestinal diseases, and cancer) are characterized by worse outcome.
To evaluate whether the addition of colchicine to standard of care (SOC) results in better outcomes in hospitalized patients with COVID-19.
This interventional, multicenter, randomized, phase 2 study, evaluated colchicine 1.5 mg/day added to SOC in hospitalized COVID-19 patients (COLVID-19 trial) and 227 patients were recruited. The primary outcome was the rate of critical disease in 30 days defined as need of mechanical ventilation, intensive care unit (ICU), or death.
152 non-anti-SARS-CoV-2-vaccinated patients (colchicine vs controls: 77vs75, mean age 69.1±13.1 vs 67.9±15 years, 39% vs 33.3% females, respectively) were analyzed. There was no difference in co-primary end-points between patients treated with colchicine compared to controls (mechanical ventilation 5.2% vs 4%, ICU 1.3% vs 5.3%, death 9.1% vs 6.7%, overall 11 (14.3%) vs 10 (13.3%) patients, P=ns, respectively). Mean time to discharge was similar (colchicine vs controls 14.1±10.4 vs 14.7±8.1 days). Older age (>60 years, P=0.025), P/F<275 mmHg (P=0.005), AST>40 U/L (P<0.001), pre-existent heart (P=0.02), lung (P=0.003), upper-gastrointestinal (P=0.014), lower-gastrointestinal diseases (P=0.009) and cancer (P=0.008) were predictive of achieving the primary outcome. Diarrhoea (9.1% vs 0%, p=0.0031) and increased levels of AST at 6 days (76.9±91.8 vs 33.5±20.7 U/l, P=0.016) were more frequent in the colchicine group.
Colchicine did not reduce the rate and the time to the critical stage. Colchicine was relatively safe although adverse hepatic effects require caution. We confirm that older (>60 years) patients with comorbidities are characterized by worse outcome.
Sofosbuvir (SOF)-based regimens have been associated with renal function worsening in HCV patients with estimated glomerular filtration rate (eGFR) ≤ 45 ml/min, but further investigations are ...lacking.
To assess renal safety in a large cohort of DAA-treated HCV patients with any chronic kidney disease (CKD).
All HCV patients treated with DAA in Lombardy (December 2014–November 2017) with available kidney function tests during and off-treatment were included.
Among 3264 patients 65% males, 67% cirrhotics, eGFR 88 (9–264) ml/min, CKD stage was 3 in 9.5% and 4/5 in 0.7%. 79% and 73% patients received SOF and RBV, respectively. During DAA, eGFR declined in CKD-1 (p < 0.0001) and CKD-2 (p = 0.0002) patients, with corresponding rates of CKD stage reduction of 25% and 8%. Conversely, eGFR improved in lower CKD stages (p < 0.0001 in CKD-3a, p = 0.0007 in CKD-3b, p = 0.024 in CKD-4/5), with 33–45% rates of CKD improvement. Changes in eGFR and CKD distribution persisted at SVR. Baseline independent predictors of CKD worsening at EOT and SVR were age (p < 0.0001), higher baseline CKD stages (p < 0.0001) and AH (p = 0.010 and p < 0.0001, respectively).
During DAA, eGFR significantly declined in patients with preserved renal function and improved in those with lower CKD stages, without reverting upon drug discontinuation.
