Retrospective Study of the Clinical Profile and Prognostic Indicators in Patients of Alcoholic Liver Disease Admitted to a Tertiary Care Teaching Hospital in Western Nepal

Background/Aim:

Alcohol is the most common substance abused in Nepal. Liver disease caused by alcohol abuse, including its end stage, cirrhosis, is a major health care problem, which is difficult to treat.

Objectives:

To study the demographic profile, laboratory parameters, complications and their prognostic implications among patients of alcoholic liver disease (ALD).

Materials and Methods:

Records of all patients of ALD admitted from January 1'' 2005 to December 31'' 2006 were studied and followed up to December 31, 2007. A total of 181 patients were analyzed. Their clinical profile and laboratory parameters were noted and analyzed using SPSS-10.0 software.

Results:

Among the 181 patients, 80.7% were male, 30.9% were army/ex-army and 65.2% were documented smokers. The mean age of presentation was 52.08 years. Jaundice (57.5%) was the most common presentation followed by hepatomegaly (51.4%). Hypoalbuminemia (50.3) followed by ascites (48.1) were common complications. Death occurred in 19.1% of the patients, the most common cause being hepatic encephalopathy (72.2%) followed by variceal bleeding and hepatorenal syndrome. Jaundice, ascites and hepatic encephalopathy at presentation and female sex were significantly associated with increased mortality along with discriminant score >32, aspartate aminotransferase (AST): Alanine aminotranferase (ALT) ≥ 2, ultrasonography (USG)-proven cirrhosis, rise in prothrombin time ≥5 s, total bilirubin ≥ 4mg/dL and ESR ≥34.

Conclusion:

ALD was predominantly seen among the productive age group with a high morbidity and mortality. Jaundice, ascites, hepatic encephalopathy at presentation and female sex are poor prognostic indicators along with discriminant score > 32, AST:ALT ≥ 2, USG-proven cirrhosis, coagulopathy, hyperbilirubenemia and high ESR.     

Copper concentrations in Egyptian infants with cholestasis: A single center study

Background and study aims

Hepatobiliary cholestatic disorders produce excess copper (Cu) retention in the liver, which is toxic and may cause hepatitis, fulminant hepatic failure, cirrhosis and death. In this study, we measured hepatic Cu and tested its correlation with serum Cu (S. Cu) and serum ceruloplasmin (S. ceruloplasmin) in cholestatic infants.

Total parenteral nutrition-associated cholestasis and risk factors in preterm infants

Background/Aim:

Development of hepatic dysfunction is a well-recognized complication of total parenteral nutrition in preterm infants. Previous studies reported the incidence of total parenteral nutrition–associated cholestasis and described possible contributing factors to its pathogenesis, but little is done trying to determine its possible predictive risk factors. The aims of this study was to determine the incidence of total parenteral nutrition–associated cholestasis and to develop a possible predictive model for its occurrence.

Patients and Methods:

A review of medical records of all very low birth weight infants admitted to neonatal intensive care unit at King Khalid University Hospital, Riyadh, Saudi Arabia, between January 2001 and December 2003 was carried out. The infants were divided into two groups: Cholestasis and noncholestasis, based on direct serum bilirubin level >34 μmol/L. A multivariate logistic regression analysis was performed to calculate the statistical significance of risk factors. Receiver–operating characteristic curve was used to determine the optimal cutoff points for the significant risk factors and to calculate their sensitivity and specificity. The level of significance was set at P ≤ 0.05.

Results:

A total of 307 patients were included in the analysis. The incidence of cholestasis in the whole population was 24.1% (74 patients). Infants with cholestasis had a lower birth weight, 735.4 ± 166.4 g vs. 1185.0 ± 205.6 g for noncholestasis group (P < 0.001), whereas the mean gestational age for the two groups was 25.4 ± 2.1 week and 28.9 ± 2.1 week, respectively (P < 0.001). The significant risk factors for the development of cholestasis were birth weight (P = 0.006) with an odds ratio of 0.99 [95% confidence interval (CI), 0.98, 0.99]; sensitivity of 92%, specificity of 87%; and total parenteral nutrition duration (P < 0.001) with an odds ratio of 1.18 (95% CI, 1.10, 1.27); sensitivity of 96%, specificity of 89%.

Conclusions:

A lower birth weight and longer duration of total parenteral nutrition were strong predictive risk factors for the development of cholestasis in preterm infants.     

Increased liver stiffness in extrahepatic cholestasis caused by choledocholithiasis

Background

Extrahepatic cholestasis that is caused by benign and malignant diseases has been reported to increase liver stiffness (LS), as measured by transient elastography (TE).

Objectives

The aim of this study was to evaluate LS in patients with extrahepatic cholestasis due to choledocholithiasis before and after endoscopic sphincterotomy and stone removal.

Patients and Methods

LS was measured by TE (Fibroscan) in patients with extrahepatic cholestasis that was caused by choledocholithiasis before and 1 month after endoscopic sphincterotomy and successful stone removal.

Results

We studied 12 patients (7 females, 5 males), aged 36 to 76 years (mean age 57.1 ± 11.6 years), with extrahepatic cholestasis that was caused by choledocholithiasis. LS was increased in all patients (range: 6.2-18.4 kPa; mean: 8.9 ± 3.5 kPa) before endoscopic therapy. Successful biliary drainage was effected by sphincterotomy and stone removal in all patients, which led to a significant decline in LS to 3.9-8.1 kPa (Mean: 5.6 ± 1.2 kPa; p < 0.001) within a mean observation time of 29 days. The decrease in LS values correlated significantly with a decline in serum total bilirubin levels (r = 0.691; p < 0.0001).

Conclusions

Extrahepatic cholestasis due to choledocholithiasis increases LS and should be excluded before assesing liver fibrosis by transient elastography.     

Serum mannan-binding lectin in egyptian patients with chronic hepatitis C: its relation to disease progression and response to treatment

Background

Chronic hepatitis C virus (HCV) infection is a major worldwide public health problem. Egypt has the highest prevalence of adult HCV infection in the world, averaging 15%–25% in rural communities. Mannan-binding lectin (MBL) is a liver-derived pluripotent serum lectin that plays a role in the innate immune system of the host. It is an acute-phase protein that is involved in the activation of the classical complement pathway. MBL may play a defensive role in HCV infection.

Objectives

To investigate the relationship between MBL concentration and HCV infection in Egyptian patients suffering chronic hepatitis C.

Patients and Methods

Serum samples obtained from 35 Egyptian hepatitis C patients and 30 normal controls were assayed for MBL. MBL concentrations were correlated to disease characteristics and treatment response.

Results

Serum MBL was significantly higher in HCV patients than in controls, but no relationship was found between MBL concentration and disease progression in terms of hepatic fibrosis and inflammation. Responders to interferon (INF)-based therapy had significantly higher serum MBL than non-responders.

Conclusions

We found no association between serum MBL concentration and progression of HCV related liver disease. Responders to INF-based therapy had significantly higher serum MBL than non-responders.     

The impact of Hepatitis C virus infection on kidney transplantation outcomes: A systematic review of 18 observational studies: The impact of HCV on renal transplantation

Background

Hepatitis C virus (HCV) infection occursin 0% to 51% of dialysis patients, and manyHCV-positive patients are urged to undergo kidney transplantation. However, the outcome of renal transplantation in HCV-positive recipients is unknown.

Objectives

Our review aimed to address the outcomesof renal transplantation recipients (RTRs)following kidney transplantation.

Materials and Methods

We selected studies that used the adjusted relative risk (aRR) and 95% CI of all-cause mortality and graft loss in HCV-positive compared with HCV-negative RTRs as study endpoints. Cox proportional hazard analysis was usedin all studies to calculate the independent effects of HCV infection on RTR outcomes. Sixteen retrospective cohort studies and 2 clinical trials were selected for our review. Sixteen studies were related to patient survival, and 12 examined graft survival.

Results

The combined hazard ratio in HCV-infected recipients was 1.69-fold (1.33-1.97, p < 0.0001) and 1.56 times (1.22-2.004, p < 0.0001) greaterthan that of HCV-negative recipients for mortality and graft loss, respectively.

Conclusions

Although HCV-infected RTRs have worseoutcomes than HCV-negative RTRs,kidney transplantation is the preferred treatment for patients with HCV infection and end-stage renal disease.     

Presentation, Diagnosis and Outcome of Predominantly Hepatic Wilson's Disease in Adult Saudi Patients: A Single Centre Experience

Background/Aim:

To evaluate the clinical manifestations, diagnostic features, disease course and response to treatment among Saudi adults with predominantly hepatic Wilson''s disease. A retrospective cohort study of 40 adult patients diagnosed with predominantly hepatic Wilson''s disease between 1994 and 2008 at King Abdulaziz Medical City, Riyadh was carried out.

Patients and Methods:

The diagnosis was based on varying combinations of clinical and laboratory evidence of liver disease, presence of Kayser Fleisher rings, low serum ceruloplasmin levels, elevated 24 hour urinary copper excretion and histopathological findings on liver biopsy.

Results:

The most frequent clinical presentation was decompensated chronic liver disease in 19 (47.5%), followed by chronic hepatitis in 15 (37.5%) and fulminant hepatic failure (FHF) in 5 (12.5%) patients. Eight (20%) patients with end-stage liver disease had liver transplantation, while 24 (60%) patients followed up on medical treatment for a variable period of 1-12 years showed clinical and laboratory improvement. One patient was lost early in follow up. Eight (20%) patients died during the study period, 5 with FHF, and 2 with advanced hepatic and neurological disease and one seven years after liver transplantation. Mortality rate was 100% in FHF without liver transplantation.

Conclusion:

A predominantly hepatic Wilson''s disease has varied clinical presentations with decompensated chronic liver disease being the most common among adult patients. Majority of the patients show stabilization of the disease on medical treatment. FHF in Wilson''s disease has a grave prognosis without liver transplantation, the later remains a definitive treatment option for decompensated cirrhotics and patients with FHF.     

Hepatic and pancreatic resection in patients with end-stage renal disease: a propensity analysis

Background

Hepatic and pancreatic surgery is rarely performed in patients with end-stage renal disease (ESRD). The present authors used a national clinical database to characterize outcomes and perioperative risk in ESRD patients who require hepatic or pancreatic resection.

Methods

The 2005–2011 National Surgical Quality Improvement Program database was queried for all patients undergoing hepatic or pancreatic resection. Patients were classified by the presence or absence of ESRD. The independent effects of ESRD on outcomes were assessed after propensity score adjustment and multivariable logistic regression.

Results

Of the 27 376 patients submitted to hepatic or pancreatic procedures identified in the database, 101 patients were found to have preoperative ESRD. Patients with ESRD experienced perioperative mortality at a rate similar to that in those without ESRD (5.0% versus 2.3%; P = 0.08). After risk adjustment, the presence of ESRD was associated with three-fold higher odds of postoperative sepsis (adjusted odds ratio: 2.98, P = 0.014), but no significant differences in mortality or major complication rates.

Conclusions

Hepatic and pancreatic resections can be performed safely in selected patients with ESRD. These patients may have an increased risk for the development of postoperative sepsis. Further study is needed to characterize modifiable risk factors that impact outcomes in patients with ESRD who require hepatic or pancreatic resection.     

Hepatitis D virus infection in Isfahan, central Iran: Prevalence and risk factors among chronic HBV infection cases

Background

Hepatitis D virus (HDV) is dependent on hepatitis B virus (HBV) infection. Acute infection with HDV can occur simultaneously with acute HBV infection or be superimposed onto a chronic HBV infection.

Objectives

This study aimed to identify cases of HDV and determine its prevalence in patients with chronic HBV infection for the first time study in Isfahan, central Iran.

Patients and Methods

In a cross-sectional study in 2009, 346 who had been diagnosed for at least 6 months with chronic HBV were enrolled consecutively. Anti-HDV was measured by ELISA in the serum of these patients.

Results

The study included 245 males (70.8%) and 101 (29.2%) females with a mean age of 39 ± 12.4 years. Anti-HDV was present in 8 (3.5%) HBe antibody-positive patients (p = 0.36) and in 2 (2.3%) HBe antigen-positive cases (p = 0.68). No association was found between hepatitis D and probable risk factors.

Conclusions

This study demonstrates that the prevalence of HDV infection is higher in patients who are positive for HBeAb compared those who are HBeAg-positive. Therefore, most HDV antibody-positive cases in Isfahan are HBV/HDV superinfections but not coinfections.     

Valganciclovir is an effective prophylaxis for cytomegalovirus disease in liver transplant recipients

Objectives:

Cytomegalovirus (CMV) infection is responsible for significant morbidity and mortality among solid organ transplant recipients. Prophylaxis using valganciclovir (VGCV) in orthotopic liver transplant (OLT) recipients is not approved by the Food and Drug Administration and its use is controversial. This study aimed to evaluate the effectiveness of VGCV in CMV prophylaxis in OLT recipients.

Methods:

We carried out a retrospective, single-centre study including all OLT procedures performed during 2005–2008. Patients with early death (at ≤30 days), without CMV serology or prophylaxis, or with follow-up of <1 year were excluded.

Results:

The overall incidence of CMV disease was 6% (n = 9). The ganciclovir (GCV) and VGCV groups had similar incidences of CMV disease (4.6% vs. 7.0%; P = 0.4) and similar distributions of disease presentation (CMV syndrome vs. tissue-invasive CMV; P = 0.4). Incidences of CMV infection, as well as disease presentation, were similar between the high-risk (CMV D+/R−) and non-high-risk groups (P = 0.16). Although acute cellular rejection occurred more frequently in patients who developed CMV disease (P = 0.005), overall survival in these patients did not differ from that in patients who did not develop CMV infection (P = 0.5).

Conclusions:

Valganciclovir is an effective antiviral for the prevention of CMV disease in liver transplant recipients. Our data support its use in high-risk OLT patients.     

Hepatic Shock Differential Diagnosis and Risk Factors: A Review Article

Context:

Liver as an important organ has a vital role in physiological processes in the body. Different causes can disrupt normal function of liver. Factors such as hypo-perfusion, hypoxemia, infections and some others can cause hepatic injury and hepatic shock.

Evidence Acquisition:

Published research resources from 2002 to May 2015 in some databases (PubMed, Scopus, Index Copernicus, DOAJ, EBSCO-CINAHL, Science direct, Cochrane library and Google scholar and Iranian search database like SID and Iranmedex) were investigated for the present study.

Results:

Different causes can lead to hepatic shock. Most of these causes can be prevented by early resuscitation and treatment of underlying factors.

Conclusions:

Hepatic shock is detected in ill patients, especially those with hemodynamic disorders. It can be prevented by early treatment of underlying disease. There is no definite treatment for hepatic shock and should be managed conservatively. Hepatic shock in patients can increase the mortality rate.     

Optimal duration of treatment for HCV genotype 1 infection in slow responders: a meta-analysis

Background

A head-to-head comparison of the 72-week and 48-week anti-HCV therapies in slow responders with genotype 1 infection has been performed in several randomized clinical trials (RCTs).

Objectives

This review aimed at summarizing and pooling the results of these studies.

Materials and Methods

RCTs that had evaluated the 72-week vs. 48-week anti-HCV therapy (peginterferon and ribavirin) in slow responders with HCV genotype 1 infection were systematically identified. A meta-analysis was performed using the random effects model. Heterogeneity in results was assessed on the basis of the Q statistics, and publication bias was evaluated by using Harbord’s modified test. The end point was set as a sustained virological response (SVR).

Results

Data of 1206 subjects were retrieved from 7 studies. A total of 631 patients had received extended therapy. Slow virological responders who received the 72-week therapy had a significantly higher probability of achieving SVR than their counterpartswho received the 48-week therapy [RR = 1.44 (95% CI, 1.20–1.73)]. With regard to publication biases, the heterogeneity in funnel plots was not significant (P = 0.19, I2 = 30%, PHarbord = 0.1).

Conclusion

Our meta-analysis showed that the 72-week therapy with peginterferon and ibavirin is significantly superior to the standard 48-week therapy in slow responders th HCV genotype 1 infection.     

Epidemiological features of patients infected with HCV genotype 4 in Poland: Epidemiology of HCV genotype 4 in Poland

Background

Hepatitis C genotype 4 (HCV-4) is considered to be rare outside northern Africa and southern Europe.

Objectives

To describe the epidemiological characteristics of patients infected with HCV-4 in Poland.

Patients and Methods

The study group included 290 patients with HCV-related chronic liver disease and intravenous drug users with HCV infection recruited in years 2002-2006 in Podlaskie region, north-eastern Poland. In all cases, HCV infection was confirmed by HCV-RNA detection by qualitative nested RT-PCR. HCV genotype was determined by 5''UTR sequencing and comparison with known genotype-specific sequences.

Results

HCV 4 was found in 45 (15.5%) of 290 HCV-infected and HCV RNA-positive individuals. 60% of HCV 4 infections occurred in intravenous drug users; 51% of HCV 4-infected patients were also HIV-positive. Among 119 patients whose source of infection was other than drug use, there were 16 (10.5%) HCV 4 cases. Seven (46%) of 13 HCV 4-positive and HIV-negative patients who received combined antiviral treatment had sustained viral response.

Conclusions

HCV 4 exists in eastern Poland, and the infection is frequently related to intravenous drug use and accompanied by HIV infection. HCV 4 also causes a proportion of non-drug-related HCV infections.     

Hepatitis C and hepatitis B virus infection: epidemiology and risk factors in a large cohort of pregnant women in Lorestan, West of Iran

Background

There are little data on the prevalence of serological markers of hepatitis B and hepatitis C viruses in pregnant women in Iran.

Objectives

This study was designed to determine the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection among pregnant women in Lorestan, west of Iran.

Patients and Methods

Serum samples of 827 pregnant women who lived in rural (36.8%) and urban areas (63.2%) of Lorestan were collected during 2007-2008. Data were obtained through questionnaires. Samples were first screened for anti-HCV and anti-HBc by ELISA. Those who were positive for anti-HBc were tested for HBsAg.

Results

Anti-HBc was found in 28 of 827 pregnant women (overall prevalence, 3.4%; 14 of 523 in urban areas, 2.7%; 14 of 304 in rural areas, 4.6%). Of the 28 positive samples, 6(0.7%) were positive for HBs-Ag. Only 2 samples (0.2%) were anti-HCV-positive.

Conclusions

These results underscore the need for prenatal screening for HBV infection in pregnant women and treatment of newborns from HBsAg-positive mothers.More studies are needed to identify risk factors of HCV infection and highlight the importance of HCV screening and treatment programs.     

The Expression of Hepatic Carboxypeptidase E is Decreased in Patients with Cholesterol Gallstone

Background/Aims:

Decreased carboxypeptidase E (CPE) expression is associated with numerous pathophysiological conditions. This study aimed to investigate the potential function of hepatic CPE in cholesterol gallstone formation.

Patients and Methods:

Patients with cholesterol gallstone (CGS group) and patients without cholesterol gallstones (non-CGS group) were enrolled. The serum total cholesterol, triglyceride, and biliary composition were analyzed. Eight liver samples from two patients without CGS and six patients with CGS were subjected to cDNA microarray analysis. Hepatic CPE expression was detected by quantitative real-time polymerase chain reaction (qRT-PCR), Western blot, and immunohistochemical analysis. Plasma CCK level was measured by ELISA.

Results:

cDNA microarray identified CPE as a gene downregulated in the CGS group. RT-PCR showed that CPE mRNA level was lower in CGS group than in control (P < 0.05, t-test). Moreover, Western blot and immunohistochemistry analysis showed that CPE protein level was significantly lower in CGS group than in the control group. In addition, plasma CCK level was lower in CGS group than in the control group. A positive correlation was found between serum CCK level and hepatic CPE mRNA level (r2 = 0.713, P = 0.003).

Conclusions:

Down-expression of liver CPE may reduce the secretion of serum CCK and contribute to the formation of cholesterol gallstone.     

Hepatitis C and pulmonary fibrosis: Hepatitis C and pulmonary fibrosis

Background

Hepatitis C virus (HCV) is a hepatotropic and lymphotropic virus that causes hepatic and extrahepatic disease. Emerging clinical data suggest that chronic HCV infection can lead to many direct and indirect effects on the lung.

Objectives

This article discusses evidence on the relationship between HCV infection and pulmonary fibrosis to increase knowledge on this topic among clinicians and scientists and highlights the need for further study.

Methods

We searched the MEDLINE, ISI WEB OF KNOWLEDGE, OVID, ELSEVIER, and MDCONSULT databases and top respiratory journals, such as the American Journal of Respiratory and Critical Care, Chest, and Thorax for articles in English using the following keywords: hepatitis C, HCV infection, IPF, pulmonary fibrosis, and interstitial pneumonitis. We reviewed the reference lists of all identified studies.

Results

The evidence for a pathogenetic link between pulmonary fibrosis and HCV is: the higher frequency of HCV markers in IPF patients, an increase in lymphocyte and neutrophil numbers in bronchoalveolar lavage of chronic HCV infection patients, and the development of IPF in HCV-related chronic hepatitis that is treated with interferon. There is a discrepancy between studies on the frequency of HCV in IPF patients, which might be attributed to geographical differences of in the prevalence of HCV infection, selection bias in choosing the control group, and the HCV genome.

Conclusions

BAL studies in HCV infection are associated with increased counts of lymphocytes and neutrophils in BAL fluid. These studies show that HCV infection is associated with nonspecific pulmonary inflammatory reactions that are not compatible with IPF but that it can lead to pulmonary fibrosis. The other factor is interferon therapy. Interstitial pneumonia and sarcoidosis are well-documented complications of IFN therapy. More extensive cohort studies should be conducted to confirm an actual causal relationship between HCV infection and pulmonary fibrosis.     

The influence of human leukocyte antigen and IL-10 gene polymorphisms on hepatitis B virus outcome

Context

The clinical outcome of hepatitis B virus (HBV) infection is variable, ranging from spontaneous recovery to an inactive carrier state, chronic hepatitis, occult HBV infection, liver cirrhosis, or hepatocellular carcinoma.

Evidence Acquisition

This variable pattern and clinical outcomes of the infection were mainly determined by virological and host genetic factors. Since the most of host genetic factors associated with HBV infection have currently focused on human leukocyte antigen (HLA) associations and interleukin (IL)-10 gene polymorphisms, this review focuses on the recent progresses in these issues to provide prognostic markers for the outcome of HBV infection.

Results

A study on serum levels of IL-10 in occult HBV infected patients reported that the higher level of IL-10 production may suppress function of the immune system against HBV in patients with occult HBV infection. IL-10 promoter polymorphism at position -592 is associated with susceptibility to occult HBV infection.

Conclusions

Findings of this study suggest that the host HLA polymorphism is an important factor in determining outcome of HBV infection but regarding IL-10 gene promoter polymorphisms, we are still have a long way to achieve a definite conclusion.     

Natural Course of Nonmalignant Partial Portal Vein Thrombosis in Cirrhotic Patients

Background/Aim:

Portal vein thrombosis (PVT) has a high incidence in patients with liver cirrhosis and determines a poor prognosis of hepatic disease. The aim of our study was to define the natural course of partial PVT in cirrhotic patients, including survival and decompensation rates.

Patients and Methods:

We performed a prospective, cohort study, in a tertiary referral center. There were 22 cirrhotic patients with partial nonmalignant PVT, without anticoagulant treatment, who were followed-up between January 2011 and October 2013. All patients were evaluated by Doppler abdominal ultrasound and computed tomography. Kaplan–Meier method was used to determine the difference in clinical events between the study subgroups.

Results:

After a mean follow-up period of 20.22 months, partial PVT improved in 5 (22.73%), was stable in 11 (50%), and worsened in 6 (27.27%) patients. Hepatic decompensation rate at 6 and 18 months was higher in patients with worsened PVT than in those with stable/improved PVT (50% vs. 25%, P < 0.0001 and 100% vs. 56.25%, P < 0.0001, respectively). The survival rate at 6 months was 66.66% in worsened PVT group vs. 81.25% (P = 0.005) in stable/improved group, and 16.66% vs. 81.25% (P < 0.0001) at 18 months, respectively. Multivariate analysis showed that Model of End-Life Disease was the independent predictor of hepatic decompensation [hazard ratio (HR) 1.42; 95% confidence interval (CI): 1.08−1.87, P = 0.012] and survival (HR 1.76; 95% CI: 1.06−2.92, P = 0.028).

Conclusions:

Nonmalignant partial PVT remained stable/improved in over half of cirrhotic patients and aggravated in more than one fourth in whom it negatively influenced the survival and decompensation rates.     

Seroprevalence of hepatitis B virus among hemodialysis patients in Bushehr province, southern Iran: HBV seroprevalence in hemodialysis patients

Background

Hepatitis B virus (HBV) infection is still reported from adult hemodialysis units.

Objectives

To determine the prevalence of anti-HBs antibody in hemodialysis patients and the correlation between levels of anti-HBs antibody with other factors.

Patients and Methods

HBsAg, anti-HBs and anti-HBc antibodies level in 119 hemodialysis patients were evaluated by enzyme-linked immunosorbent assay.

Results

Seroconversion (anti-HBs antibody >10 IU/L) was found in 22 patients. Minimum protective antibody level was found in patients aged ≥60 years. Statistically significant correlation was not found between anti-HBs antibody and gender. Ten (8.4%) patients had abnormal ALT and/or AST. Prevalence of HBsAg, anti-HBc antibody, HBeAg and anti-HBe antibody were found in 8 (6.72%), 24 (25.16%), 2 (1.68%) and 3 (2.52%) patients, respectively.

Conclusions

Periodic assessment of anti-HBs antibody level is strongly recommended in patients undergoing hemodialysis.
