Post-infantile giant cell hepatitis in patients with primary sclerosing cholangitis and autoimmune hepatitis.
2008
In post-infancy, multinucleated giant cell hepatitis is rare. Various conditions and diseases associated with post-infantile giant cell hepatitis have been described, but the pathogenesis remains unknown. In this paper we review the case reports of four patients (3 male, 1 female; aged 22 to 32 years) with primary sclerosing cholangitis and autoimmune hepatitis. The follow-up ranges from five to seven years. All patients showed cholestasis and repeated elevation of hepatic transaminases. Patients with viral infections, metabolic disorders and toxic influences were excluded. Histopathology of liver tissue in all four patients revealed giant cell formation with up to 20 nuclei in 20-70% of al…
An evaluation of transient elastography in the discrimination of HBeAg-negative disease from inactive hepatitis B carriers
2009
Summary. Liver biopsy is frequently required in HBeAg-negative disease to determine the stage of fibrosis. It can be difficult to distinguish cohorts with undetectable HBeAg who may have varying degrees of fibrosis due to different stages of disease. We have assessed the utility of transient elastography (TE) to evaluate differences in HBeAg-negative patients. A total of 220 HBsAg-positive individuals were studied: 125 (group 1) had an inactive HBsAg carrier state and 95 (group 2) were HBeAg-negative, anti-HBe-positive patients with persistently or intermittent elevation of alanine aminotransferase (ALT) and/or HBV DNA >105 copies/mL. Mean stiffness was 4.83 ± 1.2 kPa in group 1 vs 8.53 ± …
Ultrasound detection of abdominal lymphadenomegaly in subjects with hepatitis C virus infection and persistently normal transaminases: a predictive i…
1998
The indications for liver biopsy in anti-HCV-positive patients with persistently normal alanine aminotransferase levels are not clearly established. Recent studies have correlated the presence of abdominal lymphoadenomegaly with disease severity in patients with chronic hepatitis C. Our study aimed to evaluate the frequency of abdominal lymphoadenomegaly in an anti-HCV positive blood donor population with persistently normal alanine aminotransferase and the relationship of abdominal lymphoadenomegaly with the severity of liver changes.Eighty-six anti-HCV positive blood donors (58 M, 28 F) with normal alanine aminotransferase were followed up for a median of 31 months (range 12-50). To evalu…
Blood laboratory findings in patients suffering from self-perceived electromagnetic hypersensitivity (EHS)
2009
Risks from electromagnetic devices are of considerable concern. Electrohypersensitive (EHS) persons attribute a variety of rather unspecific symptoms to exposure to electromagnetic fields. The pathophysiology of EHS is unknown and therapy remains a challenge. We hypothesized that some electrosensitive individuals are suffering from common somatic health problems. Toward this end we analysed clinical laboratory parameters including thyroid-stimulating hormone (TSH), alanine transaminase (ALT), aspartate transaminase (AST), creatinine, hemoglobine, hematocrit and c-reactive protein (CRP) in subjects suffering from EHS and in controls that are routinely used in clinical medicine to identify or…
Low- and high-density lipoprotein subclasses in subjects with nonalcoholic fatty liver disease.
2014
BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is associated with increased cardiometabolic risk. Although dyslipidemia represents a key factor in this disease, its impact on serum levels of distinct lipoprotein subfractions is largely unknown.OBJECTIVE: To assess the full low-density lipoprotein (LDL) and high-density lipoprotein (I-EDL) profiles in patients with NAFLD.METHODS: Seven LDL and 10 HDL subfractions were assessed by gel electrophoresis (Lipoprint, Quantimetrix Corporation, USA) in men with biopsy proven NAFLD (simple steatosis [n = 17, age, 34 7 years] and nonalcoholic steatohepatitis [NASH; n = 24, age, 32 +/- 6 years]). Exclusion criteria included robust alcohol consump…
Presentation and Outcomes of Pregnancy in Patients With Autoimmune Hepatitis
2018
Autoimmune hepatitis (AIH) frequently affects women of childbearing age in whom the desire to have a family raises the question regarding the potential risks for the fetus and the mother. The information on AIH in pregnant patients is scarce.1 The aims of this study were (1) to identify the risk factors associated with flares in pregnant patients diagnosed with AIH, (2) to determine the course of AIH in patients with pregnancy-related flares, and (3) to describe the outcome of AIH diagnosed in the postpartum period.
Effect of oestrogen/gestagen replacement therapy on liver enzymes in patients with Ullrich-Turner syndrome.
1995
The absence of breast development and the prevention of osteoporosis in Ullrich-Turner syndrome (UTS) require oestrogen/gestagen substitution therapy. In 8 out of 35 (23%) patients with UTS treated with conjugated equine oestrogens and cyclically with norethisterone acetate, the serum liver enzymes increased to conspicuous levels (AST 35; 20-73 U/l, ALT 92; 37-141 U/l, GGT 77; 25-227 U/l, [median; min-max]). These findings were compared with those in 41 tall girls who received a six-fold larger dose of conjugated equine oestrogens for the reduction of final height. None of these 41 girls showed abnormal serum liver enzyme levels. The conspicuous rise in serum liver enzyme levels occurred in…
Serum malondialdehyde: possible use for the clinical management of chronic hepatitis C patients
1998
Serum lipid peroxidation products are increased in inflammatory liver disease and, as we previously reported, also in chronic hepatitis C. We have performed a specific assay of malondialdehyde, the reported most abundant product of lipid peroxidation, in serum of twenty four chronic hepatitis C patients, before, during, and after interferon treatment. Liver biopsies were performed in each patient before and after interferon treatment. The results show higher serum malondialdehyde values in chronic hepatitis C patients than healthy subjects (n = 68) before interferon treatment (p < .001). Mean value of serum malondialdehyde levels after interferon treatment was significantly lower than befor…
Oxidative stress after moderate to extensive burning in humans.
2000
Lipid peroxidation products, lipid antioxidants, and hematologic and blood chemistry changes were evaluated in plasma of patients after acute burning injury involving 10% (n=8), 20% (n=8), and 40% (n=5) of total body surface area (TBSA), 24 h after burning (baseline) up to 30 days after. Markedly increased plasma levels of malondialdehyde (MDA) were observed at baseline in all patients, according to the extent of the injury, then the values declined progressively. However, levels of MDA remained above normal up to 30 days even in less injured patients. On the other hand, the plasma level of conjugated diene lipid hydroperoxides was only slightly higher than control at the baseline, then dro…
The effect of interferon on the liver in chronic hepatitis C: a quantitative evaluation of histology by meta-analysis.
1997
Several randomized clinical trials of interferon in chronic hepatitis C have examined the histological changes in paired biopsy specimens. We have attempted a quantitative evaluation by meta-analysis.Randomized Clinical Trials found by MEDLINE search were included if: a) they compared different IFN regimens with non-active treatment or with each other, b) they obtained biopsies before starting and at the time of stopping IFN in a sizable proportion of the treated and control patients, and c) they assessed the biopsy-specimens semi-quantitatively according to Scheuer's numerical scoring system or Knodell's Histological Activity Index, with quantitation of fibrosis and of lobular, portal and …
