Analysis of Quality of Life, Depression, and Sexual Function in Patients on the Liver Transplant List.

BACKGROUND: The only treatment in patients developing liver failure is liver transplantation. According to the Ministry of Health, the number of patients waiting for a liver transplantation is 2141, the average waiting period for liver transplantation is approximately 5 years, and 15-18% of these patients lose their life while waiting for transplantation. In these patients, limitations in daily activities and depression-anxiety are commonly found. The aim of this study was to analyze life quality, depression symptoms, and existence of sexual functional disorders of patients waiting for liver transplantation. METHODS: A total of 74 patients, who were registered in Baskent University Hospital between 2015 and 2018, were included into the study. Short Form-36, Beck Depression Inventory, and Arizona Sexual Experiences Scale were applied to 56 patients who approved study. RESULTS: Most of the patients were male (64.3%), and the mean age was 46 (18-64). Short Form-36 scores were low in all patients. The mean Beck Depression Inventory score of patients was found as 18.4 ± 11.3, and they were suffering from moderate depressive symptoms. According to Arizona Sexual Experiences Scale, total mean scores of males was found as 16.3 ± 5.5, and for females, it was 19.5 ± 5.3 with a statistically significant difference (P < .05). It was found that sexual dysfunction mostly had moderate to mild. CONCLUSION: Depression and sexual dysfunction are common in patients with chronic liver diseases, and their life qualities deteriorate significantly. It is anticipated that evaluation of these patients in terms of psychological issues and sexual dysfunction will increase their quality of life during the organ waiting period and affect their well-being post-transplant.

Effect of Propranolol Treatment on the Incidence of Hepatocellular Carcinoma in Patients Waiting for Liver Transplant With Cirrhosis: A Retrospective, Surveillance Study in a Tertiary Center.

OBJECTIVES: Hepatocellular carcinoma is the most frequent primary malignant tumor of the liver and the third most common cause of all cancer-related mortalities. There is a need to develop new strategies to prevent hepatocellular carcinoma, as the incidence of this cancer continues to increase despite all advancements. In this study, our aim was to determine the effects of propranolol treatment on the incidence of hepatocellular carcinoma in cirrhotic patients waiting for liver transplant. MATERIALS AND METHODS: We retrospectively reviewed the data of patients waiting for liver transplant with cirrhosis due to various causes registered at the Hepatocellular Carcinoma Surveillance Program between June 2011 and December 2017 in our center. These data were compared between patients using propranolol and those not using propranolol. RESULTS: Of the 231 patients, 135 (58.4%) were male and 96 (41.6%) were female. The mean age was 58.1 ± 14 years. We noted that 153 of total patients (66.2%) were using propranolol. Three patients (2%) were using 20 mg propranolol, 125 (81.7%) were using 40 mg propranolol, 10 (6.5%) were using 60 mg propranolol, and 15 (9.8%) were using 80 mg propranolol. Of total patients, 36 (15.6%) developed hepatocellular carcinoma, including in 12 patients (7.8%) using propranolol and 24 patients (30.8%) who did not use this agent (P < .001). Thus, the hepatocellular carcinoma frequency was 5.22 times lower in patients receiving propranolol than in those not receiving propranolol. CONCLUSIONS: Although causes of cirrhosis and initial stages were similar in both groups using and not using propranolol, incidence of hepatocellular carcinoma was significantly lower in the propranolol group than in the group without propranolol. This result showed that propranolol treatment has a protective effect for hepatocellular carcinoma in patients waiting for liver transplant with cirrhosis.

Successful Treatment With Direct-Acting Antiviral Agents of Hepatitis C in Patients With End-Stage Renal Disease and Kidney Transplant Recipients.

OBJECTIVES: The introduction of direct-acting antiviral agents has allowed significant chances for treatment for difficult-to-treat populations. This study aimed to investigate the efficacy, tolerability, and safety of these therapies in both patients with end-stage renal disease and kidney transplant recipients with chronic hepatitis C virus infection. MATERIALS AND METHODS: This study was a retrospective analysis with prospective follow-up of patients. The antiviral combination of ombitasvir 25 mg, paritaprevir 75 mg, ritonavir 50 mg, and dasabuvir 50 mg was prescribed to patients with end-stage renal disease or kidney transplant recipients with noncirrhotic or compensated cirrhotic liver disease. The other antiviral combination consisted of sofosbuvir 400 mg and ledipasvir 90 mg, which was recommended to patients with decompensated cirrhosis or those who could not tolerate the first combination regimen. Ribavirin was given to all patients with genotype 1a hepatitis C virus infection. All clinical and laboratory data were recorded at week 4, at end of the treatment, and at 12 weeks after completion of treatment. RESULTS: In terms of efficacy, sustained virologic response at 12 weeks was achieved in 94% of patients in the end-stage renal disease group and 92% of patients in the kidney transplant group. In terms of tolerability, antiviral treatment was well tolerated in both groups. Cardiac arrest and cerebrovascular accident were seen in the end-stage renal disease group; severe mucositis and glossitis were seen in the kidney transplant group. Hospitalization was needed in 2 patients for treatment of drug interactions with tacrolimus and sirolimus. Renal allograft function worsened in 2 patients, with 1 patient having biopsyproven antibody-mediated rejection. CONCLUSIONS: We observed great efficacy and safety in both kidney transplant recipients and patients with end-stage renal disease with these agents in treatment of chronic hepatitis C. However, clinicians should remain aware of drug interactions and adverse events in this fragile patient population.

Prognostic Factors and Staging Systems in Hepatocellular Carcinoma.

There are a number of factors that should be taken into consideration when predicting the outcomes and prognosis of hepatocellular carcinoma. Four of the most important factors in determining survival are the severity of the accompanying liver disease, tumor size and number, extension of the tumor into other structures, and presence of metastases. The most common and widely accepted tumor staging systems include these 4 prognostic factors. The staging systems are (1) the tumor-node-metastasis system of the American Joint Committee on cancer, (2) the Okuda system, (3) the Barcelona Clinic Liver Cancer system, (4) the Cancer of the Liver Italian Program score; (5) the recent albumin-bilirubin grading system, and finally (6) the Hong Kong Liver Cancer staging system. The successful staging of patients with hepatocellular carcinoma is difficult because of the many contributing factors to disease. Therefore, in clinical practice, there is no ideal system that can be applicable to every patient in predicting survival. As a general rule, patient and treatment modality selection criteria should be individualized for every patient and should not use an algorithmic approach because aggressive treatments in properly selected patients with hepatocellular carcinoma offer good results. A better approach for increased treatment success is one that is multidisciplinary, that is, one that considers the different variables.

Expanded Criteria for Hepatocellular Carcinoma in Liver Transplant.

OBJECTIVES: Hepatocellular carcinoma is the sixth most common cancer worldwide and is the third highest cause of malignancy-related death. Because of its typically late diagnosis, median survival is approximately 6 to 20 months, with 5-year survival of < 12%. Hepatocellular carcinoma typically arises in the background of cirrhosis, with liver transplant regarded as the optimal therapy for selected patients. Initially, orthotopic liver transplant was limited to patients with extensive unresectable tumors, resulting in uniformly dismal outcomes due to high tumor recurrence rates. Here, we evaluated our long-term results with expanded-criteria liver transplant. MATERIALS AND METHODS: From December 1988 to January 2017, we performed 552 liver transplants at Baskent University. In candidates with hepatocellular carcinoma, our expanded criteria for liver transplant is applied regardless of tumor size and number, includes those without major vascular invasion and without distant metastasis, and those with negative cytology (if the patient has ascites). Since 1994, of 61 liver transplants for hepatocellular carcinoma, 36 patients received transplants according to our expanded criteria. RESULTS: Of 36 expanded-criteria patients, 11 were children and 25 were adults. Sixteen patients (4 pediatric, 12 adult) were within our expanded criteria both radiologically and pathologically before transplant. The other 20 patients (7 pediatric, 13 adult) were within Milan criteria radiologically before transplant; however, after liver transplant, when pathologic specimens were evaluated, patients were found to be within our center's expanded criteria. During follow-up, 9/36 patients (25%) had hepatocellular carcinoma recurrence. In pediatric patients, 5-year and 10-year survival rates were 90%; in adults, 5-year survival was 58.7% and 10-year survival was 49.7%. Overall 5-year and 10-year survival rates were 71.7% and 62.7%. CONCLUSIONS: Liver transplant is safe and effective in patients with hepatocellular carcinoma in combination with interventional radiology procedures, regardless of tumor size and number, without major vascular invasion and distant metastasis.

The safety and efficacy of ERCP in the pediatric population with standard scopes: Does size really matter?

Experience with endoscopic retrograde cholangiopancreatography in the pediatric population is limited. The aim of this study was to evaluate the outcomes of ERCP in the pediatric population performed by adult gastroenterologists with standard duodenoscopes. This study is a structured retrospective review of endoscopic reports, computerized and paper medical records, and radiographic images of patients under the age of 18 who underwent ERCP for any indication at a tertiary referral centre. Data regarding demographic characteristics and medical history of patients, indications, technical success rate, final clinical diagnosis, and complications were analyzed. Forty-eight children with a mean age of 13 years (range 2-17) underwent a total of 65 ERCPs. The indications of ERCP were as follows; suspected choledocholithiasis (55 %), post-liver transplantation anastomotic biliary strictures (21 %), post-surgical bile duct injury (10 %), choledochal cyst (2 %), recurrent or chronic pancreatitis (10 %), and trauma (2 %). The cannulation success rate in the overall procedure was 93.8 %. Therapeutic interventions were performed in 70.7 % of patients. Post ERCP pancreatitis was the most common complication occurring in 9.2 % of patients, and no procedure related mortality occurred. When performed by well-trained adult gastroenterologists, the use of endoscopic retrograde cholangiopancreatography with standard duodenoscopes is safe in pediatric population.

The Effect of Hepatitis B Virus on Graft and Overall Survival in Kidney Transplant Patients.

OBJECTIVES: We investigated the effect of hepatitis B virus in kidney transplant patients in terms of patient care and survival. MATERIALS AND METHODS: We retrospectively analyzed kidney transplant patients from 1993 to 2013. A control group with negative serology was selected. The hepatitis B virus-positive group was divided into 2 subgroups based on serologic status, treatments, and treatment responses. Group A had viral suppression, and group B had hepatitis B virus DNA persistence. Overall and allograft survival rates were compared. RESULTS: We identified 32 hepatitis B virus-positive and 74 hepatitis B virus-negative patients. Positive group was treated with lamivudine (n = 23), lamivudine plus entecavir (n = 4), lamivudine plus tenofovir (n = 4), or lamivudine plus entecavir and tenofovir (n = 1). In group A (n = 15), antiviral treatment was given based on the presence of either hepatitis B surface antigen with negative hepatitis B virus DNA (n = 11) or hepatitis B virus DNA positivity (n = 4). Group B patients (n = 17) received antiviral treatment for persistence of hepatitis B virus DNA (n = 7) or for viral reactivation (ie, recurrence of hepatitis B virus DNA) (n = 10). Groups A and B did not differ significantly in terms of graft or overall survival. Liver biopsy was performed in 17 patients; 3 patients had high-grade fibrosis or cirrhosis, and 14 patients had normal histology or mild hepatitis. Median graft survival time was longer in positive group (69.5 mo vs 54 mo; P = .007). Five- and 10-year overall survival rates were comparable (89%-84% vs 96%-96%; P = .107). CONCLUSIONS: Hepatitis B virus-positive kidney transplant patients have increased liver transaminase levels, longer graft survival times, and similar median overall survival rates compared with hepatitis B virus-negative patients.

Significance of Colonoscopic Findings in Patients After Kidney Graft.

OBJECTIVES: We aimed to investigate the colonoscopy findings in patients after kidney transplant. MATERIALS AND METHODS: We retrospectively analyzed kidney transplant patients who had colonoscopy examinations for various indications between 2011 and 2015. RESULTS: Eighty-one patients (25 women and 56 men) with a mean age of 39 years (range, 18-64 y) were identified. Mean follow-up after transplant was 9 years (range, 1-29 y). The most common indications for colonoscopy were diarrhea (41%), anemia (29%), gastrointestinal bleeding (12%), abdominal pain (12%), and unexplained weight loss (6%). Either colitis or ileitis or both were diagnosed in 20 patients (25%), whereas polyps were found in 9 patients (11%). One patient presented with hematochezia, which was diagnosed as cytomegalovirus colitis. The remaining cases of colitis or ileitis were diagnosed as nonspecific inflammation. Indications for colonoscopy were not correlated with age, duration after transplant, or use of immunosuppressive drugs. A subgroup analysis for mycophenolate-induced colitis found that 88% of patients used mycophenolate, but presence of colitis or ileitis had no statistical correlation with its use. In patients with poor gastrointestinal symptoms, the only significant predictor of presence of colitis or ileitis was a high C-reactive protein value (> 5 mg/dL; P = .02). CONCLUSIONS: Incidence of colitis and/or ileitis is a relatively common finding in patients after kidney transplant. Opportunistic infections, mycophenolate use, and mild degree of indeterminate colitis or ileitis disease may be the underlying condition. Cytomegalovirus infection should be screened in all recipients because it may cause serious complications or death in chronically immunocompromised patients.

Endoscopic Retrograde Cholangiopancreatography in Kidney Transplant Patients: Results From a Single Center.

OBJECTIVES: We report the outcomes of endoscopic retrograde cholangiopancreatography procedures performed for diagnostic and therapeutic purposes in patients who had undergone kidney transplant. MATERIALS AND METHODS: We retrospectively evaluated the records of kidney transplant patients for January 1993 to December 2014. Endoscopic retrograde cholangiopancreatography was carried out using an Olympus JF240 duodenoscope (tip outer diameter 12.6 mm, working channel diameter 3.2 mm). The procedures were performed by Department of Anesthesiology staff while the patients were deeply sedated, given a combination of midazolam plus propofol. RESULTS: Data from 21 kidney transplant patients (16 men and 5 women; mean age at endoscopic retrograde cholangiopancreatography 42.6 ± 23.4 y) were evaluated. A total of 23 endoscopic retrograde cholangiopancreatography procedures were performed. The indications were choledocholithiasis in 6 patients (28.6%), common bile duct dilatation plus liver enzyme elevations in 4 patients (19%), liver enzyme elevation alone in 4 (19%), biliary necrotizing pancreatitis in 2 (9.6%), and cholangitis in 5 (23.8%). Hepatobiliary ultrasonography findings showed that 3 patients (14.3%) had absence of gallbladder owing to cholecystectomy, 14 (66.7%) had gallstones, 1 (4.7%) had gallstones with cholecystitis findings, and 3 (14.3%) were normal. Endoscopic retrograde cholangiopancreatography findings were normal in 4 patients (19%), showed cholangitis in 2 (9.6%), choledocholithiasis in 10 (47.6%), bile duct wall irregularities in 2 (9.6%), dilated common bile duct in 2 (9.6%), and cholangiocarcinoma in 1 (4.7%). Sphincterotomy was performed in 16 patients. None of the patients who underwent endoscopic retrograde cholangiopancreatography developed any complications, for example, acute pancreatitis, bleeding, duodenal, or bile duct perforation. CONCLUSIONS: In kidney transplant patients, endoscopic retrograde cholangiopancreatography is safe and able to provide substantial information for managing biliopancreatic diseases.

Late-Onset Drug-Induced Cholestasis in a Living-Related Liver Transplant Donor With Progressive Familial Intrahepatic Cholestasis.

We present a rare case of progressive familial intrahepatic cholestasis within a family. A 34-yearold female became a living-related liver transplant donor for her son, who had the disease. Nine years after the transplant, the mother developed severe intrahepatic cholestasis, for which she was evaluated after using an oral contraceptive drug. She presented with jaundice, pruritus, and increased bilirubin levels, together with elevated gamma glutamyl transferase and alkaline phosphatase levels. A liver biopsy revealed findings consistent with intrahepatic cholestasis. However, despite follow-up management and cessation of the insulting drug, her total bilirubin count continuously increased to 20 mg/dL and was accompanied by intractable pruritus. A total of 9 plasmapheresis sessions were performed, and she was started on a regimen of ursodeoxycholic acid (13 mg/kg/d) and cholestyramine (4 g, 3 times daily). The clinical and laboratory picture dramatically improved following cessation of the oral contraceptive, plasmapheresis sessions, and drug treatment. The patient's cholestasis normalized within 3 months, and she recovered uneventfully. A genetic analysis of the whole family revealed that both parents were heterozygous for the mutation c.124G>A in ABCB11, and the son was homozygous for this mutation. These findings supported varying degrees of bile salt export pump deficiency in the family members. Defective bile salt excretory system function can result in a wide spectrum of clinical presentations, ranging from progressive familial intrahepatic cholestasis requiring liver transplant to late-onset drug-induced cholestasis. Our findings suggest that, in a heterozygous carrier of a progressive familial intrahepatic cholestasis mutation, drug-induced cholestasis is responsive to treatment, after which the clinical picture can normalize within 3 months.

Fractalkine receptor polymorphism may not be associated with the development and clinical course of ulcerative colitis.

Fractalkine (CX3C), a chemokine expressed by epithelial cells within normal and inflamed colorectal mucosa, induces leukocyte adhesion and migration via fractalkine receptor. The aim of this study was to investigate two single nucleotide polymorphisms of the fractalkine receptor gene as a risk factor both for the development and clinical findings of ulcerative colitis. In this study, 51 patients with ulcerative colitis (UC) and 80 controls were recruited. Genotypes of fractalkine receptorc.745G>A (V249I) and c.839C>T (T280M) polymorphisms were identified by restriction fragment length polymorphism analyses after polymerase chain reaction.Genotype distribution and allele frequencies of V249I and T280M were not statistically significantly different between UC and control groups (p>0.05). No statistically significant relationship was found between fractalkine receptor polymorphisms and clinical findings of UC. We observed no significant difference in fractalkine receptor polymorphism between patients and control group and no genotype-phenotype relation. Therefore, we concluded that fractalkine receptor polymorphisms may not contribute to the molecular pathogenesis of UC.

Importance of malnutrition in patients with cirrhosis.

Malnutrition is common in patients with chronic liver disease and is associated with poor outcomes. Inadequate intake, poor quality diet, maldigestion, malabsorption, altered macronutrient metabolism, and hypermetabolism all contribute to the development of malnutrition in this patient population. Although it is generally easy to detect, clinicians often overlook malnutrition and its measurement is complicated by the lack of a simple, standardized diagnostic method. Early detection of malnutrition and multidisciplinary treatment approaches greatly increase the probability for successful outcomes.

Hepatitis B- and hepatitis D-virus-related liver transplant: single-center data.

OBJECTIVES: Hepatitis B and D virus coinfection or superinfection lead to chronic liver disease and have poor treatment results and poor prognosis. After transplant, these patients have difficult problems. We aimed to report long-term data of liver transplant recipients who had hepatitis B and D virus-related chronic liver disease. MATERIALS AND METHODS: This retrospective, longitudinal study included 25 consecutive hepatitis B surface antigen-positive patients with antihepatitis D virus antibodies. Patient data (age, sex, antiviral treatment, posttransplant use of hepatitis B hyperimmunoglobulin and/or nucleoside/nucleotide analogues, the presence of hepatocellular carcinoma, age at transplant, follow-up) were extracted from patient records. RESULTS: Females comprised 32% patients. The median age was 44 years (range, 23-63 y). The serum Hepatitis B envelope antigen level was negative in all patients. At the time of transplant, 4 patients were positive for hepatitis B virus DNA and 11 patients also had hepatocellular carcinoma. Posttransplant follow-up was 59 months (range, 3-120 mo). During follow-up, 4 patients died, 4 patients were lost to follow-up, and 17 patients were alive. Posttransplant survival of patients with hepatocellular carcinoma was 50.45 months (range, 3-84 mo) and without hepatocellular carcinoma was 65.8 months (range, 4-120 mo). There were 3 patients who had acute rejection and were treated successfully with pulse doses of prednisolone. Hyperimmunoglobulin therapy was used in conjunction with oral nucleotide/nucleoside analogues for 12 months (range, 3-24 mo) and then stopped. After transplant, 4 patients had antiviral medicine changed to adefovir or entecavir because of drug resistance, and otherwise all patients remained negative for hepatitis B virus DNA during follow-up. CONCLUSIONS: Patients transplanted for hepatitis B and D virus cirrhosis, even with hepatocellular carcinoma, had favorable prognosis and good longterm results. Close follow-up of patients and effective viral suppression with suitable drugs were key factors for efficient patient care.

Progression of hepatic histopathology in kidney transplant recipients with chronic hepatitis C virus infection and effect of immunosuppression on the course of hepatitis C virus infection.

OBJECTIVES: There is no correlation between alanine aminotransferase levels, viral load, and histologic findings at dialysis in patients with chronic hepatitis C virus infection. Identification of the severity of hepatitis C-related liver disease before transplant could provide valuable data about the risk for liverrelated mortality after transplant. In this study, we aimed to identify the severity of liver disease in endstage renal disease patients with chronic hepatitis C virus infection, the progression of hepatic histopathology after kidney transplant, and whether immunosuppressive therapy affected posttransplant viral replication and hepatic histology. MATERIALS AND METHODS: Antihepatitis C viruspositive kidney transplant recipients (45 patients) enrolled in the study. Liver biopsy was performed in 45 patients before and 16 patients after kidney transplant. Interferon was given to 28 of 45 patients before kidney transplant. Biopsy before and after kidney transplant was performed in 5 of 14 patients. RESULTS: Patients had higher viral load, with genotype 1 predominancy (91%). Sustained viral response was achieved in 14 of 28 patients (50%). The histopathologic features of 45 patients who had pretransplant liver biopsy were as follows: 22 patients had mild hepatocellular injury, 17 patients had mild chronic hepatitis, 5 patients had moderate chronic hepatitis, and 1 patient had serious hepatitis. Follow-up biopsy after kidney transplant (mean, 2 y) in 16 of 45 patients showed that 3 of 16 patients had mild hepatocellular injury, 4 of 16 patients had mild hepatitis, 6 of 16 patients had moderate hepatitis, 2 of 16 patients had serious hepatitis, and 1 patient had cirrhosis. Patients showed neither progression, regression, nor stable liver histology. CONCLUSIONS: Even with worse genotype profiles, chronic hepatitis C virus infection has an indolent progression in patients with end-stage renal disease and kidney transplant. Follow-up biopsies of kidney transplant recipients show reasonable progression during the first 2 years.

The effect of pretransplant chronic hepatitis C virus infection treatment on graft and patient survival in renal transplant recipients.

OBJECTIVES: Studies have demonstrated worse graft and patient survival among hepatitis C virus-positive patients following kidney transplant. Eradication of hepatitis C virus infection before renal transplant with interferon should be considered in hepatitis C virus-infected patients undergoing dialysis who are on the waiting list for transplant. We investigated whether pretransplant hepatitis C virus infection treatment affected graft and patient survival, and we evaluated other contributing factors to these outcomes. MATERIALS AND METHODS: We enrolled 83 antihepatitis C virus-positive patients who were diagnosed with chronic hepatitis C virus infection by serology or histopathology and had renal transplant at Baskent University Ankara Hospital from 1982 to 2013. Data were obtained from patient medical files retrospectively. Patients were divided into 2 groups that had or did not have interferon treatment. RESULTS: In 83 renal transplant patients with chronic hepatitis C virus infection (57 male [69%] and 26 female [31%]), median age was 46 years (range, 26 - 69 y), and most patients were genotype 1-dominant (92%). Interferon monotherapy was received by 30 patients before renal transplant and 28 of 30 patients had long-term follow-up data. There were 14 of 28 patients (50%) who achieved sustained virologic response, and only 1 patient had relapse. Graft survival was significantly lower in patients who had treatment (6 y vs 9 y; P ≤ .003). However, patient survival rates were similar between groups. Patients who had interferon were younger and had longer hemodialysis duration before renal transplant than patients without treatment. Higher viral load was associated with higher mortality which was caused by sepsis. CONCLUSIONS: Patients with posttransplant lymphoproliferative disorder have high incidence of bone marrow involvement and high mortality rates. Therefore, bone marrow examination may be important in the diagnosis and staging evaluation of posttransplant lymphoproliferative disorder.

Panel reactive antibodies in predicting hepatitis C virus treatment outcome in kidney transplant candidates.

OBJECTIVES: Chronic hepatitis C virus infection compromises hemodialysis patients and increases liver-related mortality. Interferon treatment is associated with improved sustained virological response rates and increased risk of graft loss after kidney transplant. This may be related to the development of antihuman leukocyte antigen antibodies, which may be a surrogate marker of potent immune response. We evaluated panel reactive antibody 1 and 2 levels for prediction of sustained viral response in patients with kidney transplant. MATERIALS AND METHODS: In this retrospective cohort study, we reviewed data from hepatitis C virusinfected hemodialysis patients who received interferon treatment before kidney transplant. Panel reactive antibody > 20% was considered positive. Sustained viral response rates for interferon treatment were obtained and compared with panel reactive antibody 1 and 2 values. RESULTS: There were 40 patients (16 female and 24 male patients; mean age, 41.5 y; range, 18-65 y). Sustained viral response rate was 18/40 (45%). Panel reactive antibody 1 was negative in 31 patients and positive in 9 patients. Sustained viral response ratio was not correlated with panel reactive antibody 1 positivity. Panel reactive antibody 2 was negative in 31 patients (sustained viral response: present, 11 patients; absent, 20 patients) and positive in 9 patients (sustained viral response: present, 7 patients; absent, 2 patients). Sustained viral response ratio was significantly correlated with panel reactive antibody 2 positivity. CONCLUSIONS: We showed a correlation between panel reactive antibody 2 positivity and sustained viral response rates that may be a predictive tool for hepatitis C virus treatment response. In patients with other complications that compromise hepatitis C virus treatment, panel reactive antibody 2 may be a surrogate marker for sustained viral response prediction. The induction of cellular immunity may cause clearance of hepatitis C virus infection and formation of high panel reactive antibody 2 levels.

Terlipressin and albumin for type 1 hepatorenal syndrome: does bacterial infection affect the response?

Vasoconstrictor therapy with terlipressin and concomitant albumin can improve renal function in patients with hepatorenal syndrome (HRS) type 1, but the efficacy of therapy in patients with active infection is controversial. The aim of this study was to investigate the efficacy, adverse effects, and predictors of terlipressin therapy and to find out whether there was a difference in response rates between the patients with or without active infections. Data of 58 patients with type 1 HRS treated with terlipressin and albumin were retrospectively evaluated. Twenty-six patients (44.8 %) showed complete response to treatment. Response rates of patients with or without active bacterial infection were 47 and 43.9 %, respectively (p > 0.05). Only baseline serum creatinine level was significantly related to response in univariate/multivariate analyses (p < 0.05). Twenty-three patients (39.6 %) developed adverse effects probably related to treatment. In 8.6 % of patients, treatment was discontinued because of adverse effects of therapy. Four patients (6.9 %) developed ischemic adverse events, including nonfatal myocardial infarction, intestinal ischemia, and cutaneous necrosis. Terlipressin plus albumin therapy improved renal function in nearly half of patients with type 1 HRS. Thus, it seems a reasonable treatment for patients with active bacterial infections. Baseline serum creatinine level is a potential predictor of terlipressin response.
