ABSTRACTThe pharmacokinetics of lipid-bound and liberated amphotericin B (AMB) was assessed in 11 critically ill patients with cholestatic liver disease (CSLD) and in 9 subjects with normal liver function treated with AMB colloidal dispersion (ABCD). Exposure to lipid-bound AMB was higher in patients with CSLD. Levels of liberated AMB were elevated by CSLD only after the first dose, whereas its pharmacokinetics was unaffected at steady state. The standard dosage of ABCD is probably adequate for patients with CSLD.

Background: Sickle cell disease (SCD) is often associated with liver disease. The constant state of haemolysis, multiple blood transfusion, viral hepatitis, hepatic sinusoidal congestion, haemosiderosis and cholestasis, are all conditions which may eventually evolve into liver disease. Sickle cell disease is a heterogeneous group of disorders that is usually associated with an autosomal recessive structural haemoglobin disorder. Biochemical abnormalities have been associated with SCD and it is usually more pronounced in vaso occlusive crises; an acute bone crisis and common painful complication of SCD, than in steady state. Aim: The aim of the study was to assess some biochemical parameters in relation to SCD patients in our environment with a view to improving the monitoring and management of these patients.  Methodology: The study was a comparative hospital based research carried out at the University of Calabar Teaching Hospital (UCTH), Calabar, South-South Nigeria. Liver function tests were carried out on 60 SCA both in steady state and in crisis and also on 50 apparently healthy adults.  The data collected were analyzed using statistical data for social sciences (SPSS) Version 22 for windows. Pearson linear correlation and simple inferential statistical methods were employed for data analysis, a P ≤ 0.05 was considered to be statistically significant. Result: The serum concentrations of AST, ALT, ALP, LDH, Total and conjugated bilirubin were seen to be elevated in VOC compared to in steady state and with the apparently healthy control group. The AST/ALT ratio was also observed to be elevated in VOC as compared with the steady state and the control. Significant product moment correlation was observed in the biochemical parameters both in steady state and in VOC. Conclusion: The findings of this study revealed marked changes in the biochemical parameters of the liver in VOC than in steady state. It will be recommended that routine evaluation and proper interpretation of liver enzymes is paramount in early detection of liver pathology in SCD.

Liver Biopsies

Mitochondrial alterations were studied in 25 liver biopsies from patients with alcoholic liver disease. Of special interest were the morphologic resemblance of certain fine structural variations in mitochondria and crystalloid inclusions. Four types of alterations within mitochondria were found that seemed to relate to cytoplasmic crystalloids.Type 1 alteration consisted of localized groups of cristae, usually oriented in the long direction of the organelle (Fig. 1A). In this plane they appeared serrated at the periphery with blind endings in the matrix. Other sections revealed a system of equally-spaced diagonal lines lengthwise in the mitochondrion with cristae protruding from both ends (Fig. 1B). Profiles of this inclusion were not unlike tangential cuts of a crystalloid structure frequently seen in enlarged mitochondria described below.

Differential Pumping

Use of the electron microscope to examine wet objects is possible due to the small mass thickness of the equilibrium pressure of water vapor at room temperature. Previous attempts to examine hydrated biological objects and water itself used a chamber consisting of two small apertures sealed by two thin films. Extensive work in our laboratory showed that such films have an 80% failure rate when wet. Using the principle of differential pumping of the microscope column, we can use open apertures in place of thin film windows.Fig. 1 shows the modified Siemens la specimen chamber with the connections to the water supply and the auxiliary pumping station. A mechanical pump is connected to the vapor supply via a 100μ aperture to maintain steady-state conditions.

Wound Healing Response

Abstract Fibrosis results from a disordered wound healing response within the liver with activated hepatic stellate cells laying down dense, collagen-rich extracellular matrix that eventually restricts liver hepatic synthetic function and causes increased sinusoidal resistance. The end result of progressive fibrosis, cirrhosis, is associated with significant morbidity and mortality as well as tremendous economic burden. Fibrosis can be conceptualized as an aberrant wound healing response analogous to a chronic ankle sprain that is driven by chronic liver injury commonly over decades. Two unique aspects of hepatic fibrosis – the chronic nature of insult required and the liver’s unique ability to regenerate – give an opportunity for pharmacologic intervention to stop or slow the pace of fibrosis in patients early in the course of their liver disease. Two potential biologic mechanisms link together hemostasis and fibrosis: focal parenchymal extinction and direct stellate cell activation by thrombin and Factor Xa. Available translational research further supports the role of thrombosis in fibrosis. In this review, we will summarize what is known about the convergence of hemostatic changes and hepatic fibrosis in chronic liver disease and present current preclinical and clinical data exploring the relationship between the two. We will also present clinical trial data that underscores the potential use of anticoagulant therapy as an antifibrotic factor in liver disease.
