Osteoporosis in primary biliary cirrhosis of the liver

Osteoporosis is a metabolic bone disease associated with a reduction in bone mass and deterioration of bone architecture, leading to increased fragility and subsequent low-trauma fractures in the vertebral column, hip, forearm and other bones. In literature, metabolic bone diseases such as osteoporosis and osteomalacia have been recognised as a complication of chronic liver disease, although the mechanisms of this association remain unclear. An increasing body of research data indicates a strong relationship between osteoporosis and primary biliary cirrhosis (PBC), which mainly results from early diagnosis of the disease, usually when it is still asymptomatic. The incidence of osteoporosis in PBC ranges from 20% to 44% and increases with the progression of the disease. Similarly, the incidence of bone fractures is high in this group of patients (10–20%). In this article, current knowledge on risk factors, pathogenesis, diagnosis and treatment of osteoporosis in PBC is reviewed.

Prospective evaluation of PBC-specific health-related quality of life questionnaires in patients with primary sclerosing cholangitis.

Primary biliary cirrhosis and Primary sclerosing cholangitis are autoimmune cholestatic liver diseases sharing a lot in common, including a significant impairment of patients’ health‐related quality of life HRQoL HRQoL in PBC is assessed with disease‐specific PBC‐40 and PBC‐27 questionnaires. A PSC‐specific questionnaire has not been developed. Neither PBC‐40 nor PBC‐27s applicability for PSC has been evaluated. We applied these three questionnaires for HRQoL assessment in a large homogenous cohort of PSC patients.

Frequency of mutations related to hereditary haemochromatosis in northwestern Poland

Hereditary haemochromatosis has been linked with C282Y and H63D mutations of theHFE gene. In Europe, frequencies of these mutations are the highest in Northern European countries and gradually decrease southwards. We analysed the prevalence ofHFE mutations in 1517 DNA samples, including 1000 samples from the general population (subjects registered at general practitioner practices) in northwestern Poland, and 517 samples of cord blood from the same region. We identified 2 (0.13%) homozygotes and 117 (7.8%) heterozygotes for the C282Y mutation. As regards the H63D mutation (1505 DNA samples analysed), 38 (2.5%) samples were homozygotes and 380 (25%) were heterozygotes. Twenty-one (1.4%) compound heterozygotes were found. These results correspond well with data from other Central European countries and seem to confirm the hypothesis of North-South spread of the C282Y mutation.

Plasmapheresis exerts a long‐lasting antipruritic effect in severe cholestatic itch

The amelioration of refractory cholestatic pruritus after plasmapheresis has been reported in single patients. Here, we analyse the efficacy of plasmapheresis in a cohort of patients with primary biliary cholangitis (PBC).

Metabolites of arachidonic acid and linoleic acid in early stages of non-alcoholic fatty liver disease—A pilot study

BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is a spectrum of liver conditions related to fat infiltration. The role of liver triacylglycerol accumulation in NAFLD is not fully understood. METHODS Twenty-four patients, 12 in the first and 12 in the second stage of NAFLD, were prospectively enrolled in this study. Biochemical parameters and eicosanoids (HETE and HODE) were compared between the first and the second stage of hepatic steatosis and the effect of a 6-month dietary intervention on these parameters was evaluated. Eicosanoid profiles were extracted from 0.5 ml of plasma using solid-phase extraction RP-18 SPE columns. The HPLC separations were performed on a 1260 liquid chromatograph. RESULTS Patients with stage I NAFLD had a significantly higher level of HDL cholesterol and a lower level of 5-HETE. Patients with grade II steatosis had higher concentrations of 9-HODE. Following the six-month dietary intervention, hepatic steatosis resolved completely in all patients. This resulted in a significant decrease in the concentrations of all eicosanoids (LX4, 16-HETE, 13-HODE, 9-HODE, 15-HETE, 12-HETE, 5-oxoETE, 5-HETE) and key biochemical parameters (BMI, insulin, HOMA-IR, liver enzymes). CONCLUSION A significant reduction in the analyzed eicosanoids and a parallel reduction in fatty liver confirmed the usefulness of HETE and HODE in the assessment of NAFLD.

TRAF1-C5 Affects Quality of Life in Patients with Primary Biliary Cirrhosis

Background. Previous studies reported associations between specific alleles of non-HLA immunoregulatory genes and higher fatigue scores in patients with primary biliary cirrhosis (PBC). Aim. To study the relationship between variables of health-related quality of life (HRQoL) and single nucleotide polymorphisms of TRAF1-C5, a member of the tumor necrosis factor receptor family. Patients and Methods. TRAF1-C5 gene polymorphisms, rs2900180 and rs3761847, were analysed in 120 Caucasian PBCs. The HRQoL was assessed with SF-36, PBC-40, and PBC-27 questionnaires. Results. We found a negative association between TT genotype of rs2900180 and SF-36s domains vitality (P < 0.05), mental health (P < 0.05), and mental component summary score (P < 0.05). GG homozygotes of rs3761847 had lower vitality (P < 0.05), mental health (P < 0.05), mental component summary score (P < 0.05) and impairment of social functioning (P < 0.01). Allelic analysis has shown that T allele of rs2900180 and G allele of rs3761847 related to SF-36s vitality (P < 0.05 and P < 0.01), social functioning (P < 0.05 and P < 0.05), mental health (P < 0.01 and P < 0.05), and mental component summary score (P < 0.01 and P < 0.05), respectively. Genotyping and allelic analysis did not reveal correlation with PBC-40 and PBC-27 domains. Conclusion. The association between rs2900180 and rs3761847 polymorphisms and HRQoL variables indicates that TRAF1 is involved in the induction of impaired QoL in PBC.

Evolution Of The Results Of 1500 Liver Transplantations Performed In The Department Of General, Transplant And Liver Surgery Medical University Of Warsaw.

UNLABELLED Liver transplantation is a well-established treatment of patients with end-stage liver disease and selected liver tumors. Remarkable progress has been made over the last years concerning nearly all of its aspects. The aim of this study was to evaluate the evolution of long-term outcomes after liver transplantations performed in the Department of General, Transplant and Liver Surgery (Medical University of Warsaw). MATERIAL AND METHODS Data of 1500 liver transplantations performed between 1989 and 2014 were retrospectively analyzed. Transplantations were divided into 3 groups: group 1 including first 500 operations, group 2 including subsequent 500, and group 3 comprising the most recent 500. Five year overall and graft survival were set as outcome measures. RESULTS Increased number of transplantations performed at the site was associated with increased age of the recipients (p<0.001) and donors (p<0.001), increased rate of male recipients (p<0.001), and increased rate of piggyback operations (p<0.001), and decreased MELD (p<0.001), as well as decreased blood (p=0.006) and plasma (p<0.001) transfusions. Overall survival was 71.6% at 5 years in group 1, 74.5% at 5 years in group 2, and 85% at 2.9 years in group 3 (p=0.008). Improvement of overall survival was particularly observed for primary transplantations (p=0.004). Increased graft survival rates did not reach the level of significance (p=0.136). CONCLUSIONS Long-term outcomes after liver transplantations performed in the Department of General, Transplant and Liver Surgery are comparable to those achieved in the largest transplant centers worldwide and are continuously improving despite increasing recipient age and wider utilization of organs procured from older donors.

Factors Affecting Health-Related Quality of Life and Physical Activity after Liver Transplantation for Autoimmune and Nonautoimmune Liver Diseases: A Prospective, Single Centre Study

Background/Aim. With the improvement of the outcomes after liver transplantation (LTx), health-related quality of life (HRQoL) and physical activity are becoming significant outcome parameters. We prospectively assessed these parameters in patients with autoimmune and nonautoimmune liver disorders undergoing LTx. Materials and Methods. Patients (n = 107) were subdivided into 3 groups depending on the time after LTx: group-A (n = 21): 6–12 months; group-B (n = 48): 13–36 months; and group-C (n = 38): >37 months. SF-36 and IPAQ were applied in HRQoL and physical activity assessment. Results. Females had impaired HRQoL in most SF-36 domains. Younger patients showed higher scores at SF-36 physical functioning domain but IPAQ was not influenced by age. Group-B had higher general health and physical component summary than group-A (P = 0.037, P = 0.04, resp.) and total IPAQ than group-C (P = 0.047). The sitting time domain was longer in group-A than in group-B and group-C (P = 0.0157;  P = 0.042, resp.). Employed patients had better HRQoL and higher physical activity than those not working. SF-36 and IPAQ were unrelated to the autoimmune etiology of liver disease. Conclusions. These findings show that female and unemployed patients have worse HRQoL, while gender and age at LTx time do not affect IPAQs physical activity. The autoimmune etiology of liver disease does not influence HRQoL and physical activity after LTx.

Hepatic abscess: a rare complication after liver transplant.

This study was conducted to evaluate the predisposing factors, microbiology, treatment, and outcomes associated with hepatic abscess, a rare but serious complication which may accur after an orthotopic liver transplant (OLT).

Synchronous and metachronous neoplasms in gastric cancer patients: A 23-year study

AIM To determine the prevalence and characteristics of additional primary malignancies in gastric cancer (GC) patients. METHODS GC patients (862 total; 570 men, 292 women; mean age 59.8 ± 12.8 years) diagnosed at the Department of Gastroenterology at Pomeranian Medical University over a period of 23 years were included in this retrospective analysis of a prospectively maintained database. Mean follow-up time was 31.3 ± 38.6 mo (range 1-241 mo). The following clinicopathological features of patients with synchronous tumors were compared to those with metachronous tumors: age, sex, symptom duration, family history of cancer, tumor site, stage (early vs advanced), histology, and blood group. GC patients with and without a second tumor were compared in terms of the same clinicopathological features. RESULTS Of 862 GC patients, 58 (6.7%) developed a total of 62 multiple primary tumors, of which 39 (63%) were metachronous and 23 (37%) synchronous. Four (6.9%) of the 58 multiple GC patients developed two or more neoplasms. The predominant tumor type of the secondary neoplasms was colorectal (n = 17), followed by lung (n = 9), breast (n = 8), and prostate (n = 7). Age was the only clinicopathological feature that differed between GC patients with synchronous vs metachronous malignancies; GC patients with synchronous neoplasms were older than those with metachronous neoplasms (68.0 ± 10.3 years vs 59.9 ± 11.1 years, respectively, P = 0.008). Comparisons between patients with and without a second primary cancer revealed that the only statistically significant differences were in age and blood group. The mean age of the patients with multiple GC was higher than that of those without a second primary tumor (63.4 ± 11.4 years vs 59.5 ± 13.0 years, respectively, P = 0.026). GC patients with a second primary tumor were more commonly blood group O than those without (56.2% vs 31.6%, respectively, P = 0.002). CONCLUSION GC patients may develop other primary cancers; appropriate preoperative and postoperative diagnostic modalities are thus required, particularly if patients are older and blood group O.
