Abstract

Insights

Multidrug-resistant organism (MDRO) colonization significantly worsens survival in hepatocellular carcinoma (HCC) patients. Early screening and intervention are crucial for managing MDRO-colonized HCC patients.

Area of Science:

  • Oncology
  • Infectious Diseases
  • Hepatology

Background:

  • MDRO colonization is linked to poorer outcomes in various cancers and liver diseases.
  • The impact of MDRO colonization on hepatocellular carcinoma (HCC) patient prognosis remains understudied.
  • This study investigates the association between MDRO colonization and overall survival in HCC patients.

Purpose of the Study:

  • To determine the prognostic impact of multidrug-resistant organism (MDRO) colonization on overall survival in patients with hepatocellular carcinoma (HCC).
  • To identify MDRO colonization as a potential risk factor in HCC patient outcomes.

Main Methods:

  • Retrospective study of HCC patients diagnosed between January 2008 and December 2017.
  • Patients were categorized as MDRO-colonized (positive screening within 90 days of diagnosis) or non-colonized (negative screening).
  • Survival analysis was performed using multivariate analysis.

Main Results:

  • 6% of HCC patients were colonized with MDROs; Enterobacterales (ESBL/±FQ) and VRE were most common.
  • Colonized HCC patients presented with more severe cirrhosis and advanced tumor stage.
  • MDRO colonization was associated with significantly impaired overall survival (189 days vs. 1001 days) and identified as an independent risk factor.

Conclusions:

  • MDRO colonization is an independent negative prognostic factor for survival in HCC patients.
  • Highlights the critical need for routine MDRO screening and isolation protocols in HCC care.
  • Emphasizes the importance of interdisciplinary antibiotic stewardship for responsible antibiotic use.

Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow

Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment

Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

Effect of Hepatic Disease on Pharmacokinetics: Active Drug, Metabolite and Fraction of Metabolized Drug

In pharmacotherapy, monitoring drug concentrations is paramount, especially for drugs whose therapeutic effects hinge on both the active compound and its metabolite. Hepatic impairment profoundly influences drug potency by altering liver function. If the drug is more potent than its metabolite, impaired liver function amplifies drug activity due to elevated drug concentration levels. Conversely, if the metabolite holds greater potency, diminished liver function diminishes drug activity by...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...

Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
