A prospective, multicenter, three-cohort study evaluating contrast-induced acute kidney injury (CI-AKI) in patients with cirrhosis.

BACKGROUND & AIMS: Nephrotoxicity of intravenous iodinated contrast media (ICM) in cirrhosis is still a debated issue, due to scarce, low-quality and conflicting evidence. This study aims to evaluate the incidence and predisposing factors of acute kidney injury (AKI) in patients with cirrhosis undergoing contrast-enhanced computed tomography (CECT). METHODS: We performed a prospective, multicenter, cohort study including 444 inpatients, 148 with cirrhosis (cohort 1) and 163 without cirrhosis (cohort 3) undergoing CECT and 133 with cirrhosis (cohort 2) unexposed to ICM. Kidney function parameters were assessed at T0, 48-72 h (T1), 5 and 7 days after CECT/enrollment. Urinary neutrophil gelatinase-associated lipocalin (U-NGAL) was measured in 50 consecutive patients from cohort 1 and 50 from cohort 2 as an early biomarker of tubular damage. RESULTS: AKI incidence was not significantly increased in patients with cirrhosis undergoing CECT (4.8%, 1.5%, 2.5% in cohorts 1, 2, 3 respectively, p = n.s.). Most AKI cases were mild and transient. The presence of concomitant infections was the only independent predictive factor of contrast-induced AKI (odds ratio 22.18; 95% CI 2.87-171.22; p = 0.003). No significant modifications of U-NGAL between T0 and T1 were detected, neither in cohort 1 nor in cohort 2 (median ΔU-NGAL: +0.2 [-7.6 to +5.5] ng/ml, +0.0 [-6.8 to +9.5] ng/ml, respectively [p = 0.682]). CONCLUSIONS: AKI risk after CECT in cirrhosis is low and not significantly different from that of the general population or of the cirrhotic population unexposed to ICM. It mostly consists of mild and rapidly resolving episodes of renal dysfunction and it is not associated with tubular kidney injury. Patients with ongoing infections appear to be the only ones at higher risk of AKI. IMPACT AND IMPLICATIONS: Nephrotoxicity due to intravenous iodinated contrast media (ICM) in patients with cirrhosis is still a debated issue, as the available evidence is limited and based on very heterogeneous studies, often conducted on small and retrospective cohorts. In this prospective three-cohort study we found that intravenous administration of ICM was associated with a low risk of AKI, similar to that of the general population and to that of patients with cirrhosis unexposed to ICM. Patients with ongoing infections were the only ones to have a significantly increased risk of contrast-induced AKI. Therefore, the actual recommendations of performing contrast imaging studies cautiously in cirrhosis do not seem to be reasonable anymore, with the exception of infected patients, who have a significantly higher risk of contrast-induced AKI.

Cancer cachexia: A scoping review on non-pharmacological interventions.

Objective: Cancer cachexia occurs in 30%-80% of patients, increasing morbidity and mortality and impacting the health-related quality of life also for caregivers. Pharmacological interventions have been studied but have shown inconsistent effects on patients' lives in terms of relative outcomes and poor adherence to pharmacological treatment. We provide an overview of the evidence on non-pharmacological interventions for cancer cachexia. Methods: We conducted a scoping review based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses-extension for scoping review (PRISMA-ScR). On September 21, 2022, plus an update on January 10, 2024, we searched MEDLINE, Embase, CINAHL, Cochrane, PsycINFO, and Scopus for 2012-2024. We excluded pharmacological interventions defined as "any substance, inorganic or organic, natural or synthetic, that can produce functional modifications, through a chemical, physicochemical or physical action." Results: The search retrieved 9308 articles, of which 17 were eligible. Non-pharmacological interventions included nutritional counseling, complementary therapies (acupuncture), rehabilitation, and psychoeducational/psychosocial support. The data showed small and heterogeneous samples and different disease localization and stages. Thirty-nine percent were multimodal interventions and aimed at patients, not families. The common primary outcomes were body weight and composition, biomarkers, quality of life, psychological suffering, and muscular strength. Only three studies focus on the patient-caregiver dyad. Conclusions: Interventions on cancer cachexia should be multimodal and multiprofessional, proposed early, and aimed at quality of life outcomes. The caregiver's involvement is essential. Nurses can play an active role in managing cancer cachexia. More well-designed studies are needed to understand the efficacy and contents of non-pharmacological interventions. Systematic review registration: The review protocol has been registered in the OSF registry (DOI: 10.17605/OSF.IO/H4A29).

Final Results from the First European Real-World Experience on Lusutrombopag Treatment in Cirrhotic Patients with Severe Thrombocytopenia: Insights from the REAl-World Lusutrombopag Treatment in ITalY Study.

Background and aims: Management of severe thrombocytopenia poses significant challenges in patients with chronic liver disease. Here, we aimed to evaluate the first real-world European post-marketing cohort of cirrhotic patients treated with lusutrombopag, a thrombopoietin receptor agonist, verifying the efficacy and safety of the drug. Methods: In the REAl-world Lusutrombopag treatment in ITalY (REALITY) study, we collected data from consecutive cirrhotic patients treated with lusutrombopag in 19 Italian hepatology centers, mostly joined to the "Club Epatologi Ospedalieri" (CLEO). Primary and secondary efficacy endpoints were the ability of lusutrombopag to avoid platelet transfusions and to raise the platelet count to ≥50,000/µL, respectively. Treatment-associated adverse events were also collected. Results: A total of 66 patients and 73 cycles of treatment were included in the study, since 5 patients received multiple doses of lusutrombopag over time for different invasive procedures. Fourteen patients (19%) had a history of portal vein thrombosis (PVT). Lusutrombopag determined a significant increase in platelet count [from 37,000 (33,000-44,000/µL) to 58,000 (49,000-82,000), p < 0.001]. The primary endpoint was met in 84% of patients and the secondary endpoint in 74% of patients. Baseline platelet count was the only independent factor associated with response in multivariate logistic regression analysis (OR for any 1000 uL of 1.13, CI95% 1.04-1.26, p 0.01), with a good discrimination power (AUROC: 0.78). Notably, a baseline platelet count ≤ 29,000/µL was identified as the threshold for identifying patients unlikely to respond to the drug (sensitivity of 91%). Finally, de novo PVT was observed in four patients (5%), none of whom had undergone repeated treatment, and no other safety or hemorrhagic events were recorded in the entire population analyzed. Conclusions: In this first European real-world series, lusutrombopag demonstrated efficacy and safety consistent with the results of registrational studies. According to our results, patients with baseline platelet counts ≤29,000/µL are unlikely to respond to the drug.
