Screening for hepatitis C among HIV positive patients at Mulago Hospital in Uganda

Background

In industrialized countries with more resources, it is recommended that HIV infected patients should be screened for hepatitis C virus (HCV) on entry into the health care system. Implementation of these guidelines in a country like Uganda with limited resources requires some modification after taking into account the prevailing circumstances. These include the prevalence of HCV in HIV positive patients and the cost of HCV testing.

Objective

The objective of the study was to estimate the prevalence of HCV in HIV positive patients.

Methods

This was a cross sectional study among HIV positive outpatients in Mulago hospital. HCV screening was done using anti-HCV Enzyme Immuno Assay (Roche Diagnostics)

Results

Between October 2003 and February 2004, one hundred and twenty two HIV positive patients were enrolled into the study with a mean age of 33.9 years. There were more females 81 (66.4%) than males. Only 4 patients had anti-HCV, giving an estimated HCV prevalence of 3.3%.

Conclusion

In view of the low HCV prevalence found in our study and similar studies and considering the high cost of HCV screening, routine HCV testing cannot be recommended among all HIV positive patients in our health care settings with limited resources. We recommend that HCV screening be limited to investigating HIV positive patients with features suggestive of liver disease in order to identify HCV as a possible cause.     

The refit model for end-stage liver disease-Na is not a better predictor of mortality than the refit model for end-stage liver disease in patients with cirrhosis and ascites

Background/Aims

The modification of the Model for End-Stage Liver Disease (MELD) scoring system (Refit MELD) and the modification of MELD-Na (Refit MELDNa), which optimized the MELD coefficients, were published in 2011. We aimed to validate the superiority of the Refit MELDNa over the Refit MELD for the prediction of 3-month mortality in Korean patients with cirrhosis and ascites.

Methods

We reviewed the medical records of patients admitted with hepatic cirrhosis and ascites to the Konkuk University Hospital between January 2006 and December 2011. The Refit MELD and Refit MELDNa were compared using the predictive value of the 3-month mortality, as assessed by the Child-Pugh score.

Results

In total, 530 patients were enrolled, 87 of whom died within 3 months. Alcohol was the most common etiology of their cirrhosis (n=271, 51.1%), and the most common cause of death was variceal bleeding (n=20, 23%). The areas under the receiver operating curve (AUROCs) for the Child-Pugh, Refit MELD, and Refit MELDNa scores were 0.754, 0.791, and 0.764 respectively; the corresponding values when the analysis was performed only in patients with persistent ascites (n=115) were 0.725, 0.804, and 0.796, respectively. The significant difference found among the Child-Pugh, Refit MELD, and Refit MELDNa scores was between the Child-Pugh score and Refit MELD in patients with persistent ascites (P=0.039).

Conclusions

Refit MELD and Refit MELDNa exhibited good predictability for 3-month mortality in patients with cirrhosis and ascites. However, Refit MELDNa was not found to be a better predictor than Refit MELD, despite the known relationship between hyponatremia and mortality in cirrhotic patients with ascites.     

Factors influencing the severity of acute viral hepatitis A

Background/Aims

Most patients with acute viral hepatitis A have a favorable course, but a few of them suffer from severe forms of hepatitis such as fulminant hepatitis. This study was carried out to identify the factors influencing the severity of acute viral hepatitis A.

Methods

We retrospectively reviewed the medical records of 713 patients with acute hepatitis A, who were divided into two groups: severe hepatitis A (N=87) and non-severe hepatitis A (N=626). Severe hepatitis was defined as fulminant hepatitis or prolongation of prothrombin time (INR≥1.5). Clinical variables were compared between the two groups.

Results

The incidence of fulminant hepatitis was 1.4% (10/713) in patients with acute hepatitis A. Thirty-three (4.6%) cases exhibited HBsAg positivity. In multivariate analyses, significant alcohol intake and the presence of HBsAg were significant predictive factors of fulminant hepatitis A, and significant alcohol intake and age were significant predictive factors of severe hepatitis A. HBeAg and HBV-DNA status did not affect the clinical course of hepatitis A in chronic hepatitis B carriers.

Conclusions

While most patients with acute hepatitis A have an uncomplicated clinical course, our data suggest that a more-severe clinical course is correlated with being older, significant alcohol intake, and chronic hepatitis-B-virus infection.     

Clinical significance of occult hepatitis B virus infection in chronic hepatitis C patients

Background/Aims

We investigated the frequency of occult hepatitis B virus (HBV) infection in anti-hepatitis C virus (HCV)-positive individuals and the effects of occult HBV infection on the severity of liver disease.

Methods

Seventy-one hepatitis B virus surface-antigen (HBsAg)-negative patients were divided according to their HBV serological status into groups A (anti-HBc positive, anti-HBs negative; n=18), B (anti-HBc positive, anti-HBs positive; n=34), and C (anti-HBc negative, anti-HBs positive/negative; n=19), and by anti-HCV positivity (anti-HCV positive; n=32 vs. anti-HCV negative; n=39). Liver biopsy samples were taken, and HBV DNA was quantified by real-time PCR.

Results

Intrahepatic HBV DNA was detected in 32.4% (23/71) of the entire cohort, and HBV DNA levels were invariably low in the different groups. Occult HBV infection was detected more frequently in the anti-HBc-positive patients. Intrahepatic HBV DNA was detected in 28.1% (9/32) of the anti-HCV-positive and 35.9% (14/39) of the anti-HCV-negative subjects. The HCV genotype did not affect the detection rate of intrahepatic HBV DNA. In anti-HCV-positive cases, occult HBV infection did not affect liver disease severity.

Conclusions

Low levels of intrahepatic HBV DNA were detected frequently in both HBsAg-negative and anti-HCV-positive cases. However, the frequency of occult HBV infection was not affected by the presence of hepatitis C, and occult HBV infection did not have a significant effect on the disease severity of hepatitis C.     

Risk of hepatitis B and C infections in Tehranian wrestlers

Context:

Although bloodborne infections are among the most important global health issues, limited data are available on bloodborne infections in athletes.

Objective:

To determine and compare the prevalence of markers of hepatitis B (HBV) and hepatitis C (HCV) viruses and the risk factors for these infections among wrestlers in Tehran and among a control group of athletes in the same geographic area who took part in low- to moderate-contact sports (ie, volleyball and soccer).

Design:

Case-control study.

Setting:

Laboratory.

Patients or Other Participants:

A total of 420 male wrestlers were randomly selected from 28 wrestling clubs in Tehran using a cluster-sample–setting method. The control group (205 volleyball players from 21 clubs and 205 soccer players from 16 clubs) was selected from the same geographic area.

Main Outcome Measure(s):

The risk factors for HBV and HCV and serum levels of anti-HBcAg (antibodies to the HBV core antigen), HBsAg (HBV surface antigen), and anti-HCV (antibodies to HCV) in both groups.

Results:

The prevalence of anti-HBcAg was 13.4% (95% confidence interval [CI] = 10.2%, 16.7%) in wrestlers and 10.9% (95% CI = 7.9%, 14.0%) in the control group. The prevalence of HBsAg was 1.2% (95% CI = 0.2%, 2.2%) in wrestlers and 0.5% (95% CI = −0.2%, 1.2%) in the control group. The prevalence of anti-HCV was 0.5% (95% CI = −0.2%, 1.1%) in wrestlers and 0 in the control group. Some risk factors for bloodborne infections were more common in the wrestlers than in the control group.

Conclusions:

Within the limits of our study, we found no evidence that participation in Tehranian wrestling increased HBV or HCV transmission when compared with transmission in athletes participating in low- to moderate-contact sports. Prevention of bloodborne infections in Tehranian wrestlers should be focused not only on appropriate care for bleeding injuries but also on general risk factors for these conditions.     

Inact?ve hepatitis B surface antigen carriers and intrafamilial tramsmission: results of a 10-year study

Background/Aims

The aims of the present study were to determine the outcomes of inactive hepatitis B virus (HBV) surface antigen (HBsAg) carriers over a 10-year study period and to elucidate the HBV serological profile of their family members.

Methods

We retrospectively analyzed the medical files of inactive HBsAg carriers followed up at the Department of Infectious Diseases of Kocatepe University Medical Faculty Hospital between March 2001 and January 2011.

Results

In total, 438 inactive HBsAg carriers were enrolled in this trial. The follow-up period was 33.7±22.5 months (mean±SD). Anti-hepatitis-B surface antibody seroconversion occurred in 0.7% of cases, while chronic hepatitis B was found in 0.5%. The anti-hepatitis-D virus (HDV) status was evaluated in 400 patients and anti-hepatitis C virus (HCV) in 430. It was found that 1% and 0.2% were positive for anti-HDV and anti-HCV, respectively. HBV serology was investigated in at least 1 family member of 334/438 (76.3%) patients. The HBsAg positivity rate was 34.6% in 625 family members of 334 patients. A comparison of the HBsAg positivity rates in terms of HBV DNA levels in index cases revealed that HBsAg seropositivity rates were higher in family members of HBV DNA-negative patients than in family members of HBV DNA-positive cases (P=0.0001).

Conclusions

The HBsAg positivity rate was higher in family members of inactive HBsAg carriers than in the general population; these family members therefore have a higher risk of HBV transmission. Furthermore, despite negative HBV DNA levels, transmission risk was not reduced in these patients, and horizontal transmission seems to be independent of the HBV DNA value.     

Relationship between the hepatic venous pressure gradient and first variceal hemorrhage in patients with cirrhosis: a multicenter retrospective study in Korea

Background/Aims

Variceal hemorrhage is one of the major complications of cirrhosis and is associated with significant mortality and morbidity. The development of gastroesophageal varices and variceal hemorrhage is the most direct consequence of portal hypertension. Correlations between the hepatic venous pressure gradient (HVPG) and first variceal hemorrhage were examined.

Methods

Patients with cirrhosis who underwent HVPG measurement between July 2009 and September 2010 were enrolled (n=535). All patients underwent esophagogastroduodenoscopy to enable the evaluation of gastroesophageal varices.

Results

The HVPG for all patients was 16.46±7.05 mmHg (mean±SD), and was significantly higher among those with first variceal hemorrhage than in those without it. The HVPG was significantly correlated with both Child-Turcotte-Pugh (r=0.488, P<0.001) and Model for End-stage Liver Disease (r=0.478, P<0.001) scores. An HVPG value of 11 mmHg was predictive of first variceal hemorrhage with a sensitivity of 92.4% and a specificity of 27.7%.

Conclusions

The HVPG was higher in patients with first variceal hemorrhage than in those without it.     

Predictors of Refractory Ascites Development in Patients with Hepatitis B Virus-Related Cirrhosis Hospitalized to Control Ascitic Decompensation

Purpose

Refractory ascites (RA) is closely related to a high morbidity and mortality. In this study, we investigated predictors of RA development in patients with hepatitis B virus (HBV)-related cirrhosis who were hospitalized to control ascitic decompensation, and determined predictors for survival in patients who experienced RA.

Materials and Methods

We analyzed 199 consecutive patients with HBV-related cirrhosis who were hospitalized to control ascitic decompensation between January 1996 and December 2008.

Results

Multivariate analyses showed that only serum potassium at admission predicted RA development independently [p=0.013; hazard ratio (HR), 2.800; 95% confidence interval (CI), 1.166-6.722]. During the follow-up period, 16 (8.0%) patients experienced RA within 4.2 (range, 1.0-39.2) months after admission for controlling ascitic decompensation, and they survived a median of 8.7 (range, 3.9-51.3) months. Child-Pugh class and RA type were identified as independent prognostic factors affecting the survival in patients with RA (p=0.045; HR, 8.079; 95% CI, 1.231-67.984 and p=0.013; HR, 14.510; 95% CI, 1.771-118.874, respectively).

Conclusion

Serum potassium was an independent predictor of RA development in patients with HBV-related cirrhosis who were hospitalized to control ascitic decompensation. After RA development, Child-Pugh class and RA type were independent predictors for survival.     

Clinical and epidemiological aspects of hepatocellular carcinoma in Brazil

OBJECTIVES:

We performed a national survey to update hepatocellular carcinoma (HCC) epidemiology in Brazil and determined the clinical and epidemiological profiles of patients with HCC in different Brazilian regions.

METHODS:

Data from 29 centers included 1,405 patients diagnosed with HCC from 2004 to 2009.

RESULTS:

The median age was 59 (1–92 years old; 78% male). At diagnosis, females were older than males (median age: 62 vs. 59 years old respectively; p<0.0001). Ninety‐eight percent of the patients had cirrhosis (1279/1308). Hepatitis C virus was the main etiology (54%), followed by hepatitis B virus (16%) and alcohol (14%). In Southeastern and Southern Brazil, hepatitis C virus accounted for over 55% of cases. In the Northeast and North, hepatitis C virus accounted for less than 50%, and hepatitis B virus accounted for 22–25% of cases; hepatitis B was more prevalent in the Northern than in the Southern regions. Some 43%, 35%, and 22% of patients were in early, intermediate, and advanced stages respectively. Initial therapies for HCC included chemoembolization or embolization (36%), percutaneous ablation (13%), liver resection (7%), and sorafenib (1%). Liver transplantation was performed in 242 patients (19%), but it was the initial therapy for only 56 patients (4%).

CONCLUSION:

The epidemiology, classification, and therapy selection for HCC varied among Brazilian regions. Hepatitis C infection was the most common etiology of liver cirrhosis; chemoembolization was the most common therapy employed. Liver cirrhosis was the main risk factor for HCC development in Brazil.     

HBsAg level and clinical course in patients with chronic hepatitis B treated with nucleoside analogue: five years of follow-up data

Background/Aims

Quantification of the hepatitis B surface antigen (HBsAg) is increasingly used to determine the treatment response in patients with chronic hepatitis B (CHB). However, there are limited data about the clinical implications of Quantification of HBsAg long-term nucleoside analogue treatment for CHB. We investigated the clinical correlation between HBsAg level and clinical course in patients with CHB who are treated long-term with nucleoside analogues.

Methods

Patients with CHB who started lamivudine or entecavir monotherapy before June 2007 were enrolled. HBsAg was quantified at baseline, at 6 months, and at 1, 2, 3, 4, and 5 years of treatment. We compared data between the groups according to the presence or absence of a virological response (VR) and resistance.

Results

Forty-eight patients were analyzed. There was no definite reduction in HBsAg level during the early period of treatment; differences in HBsAg levels between baseline and each time point were significant only at 5 years (P=0.028). In a subgroup analysis, this difference was significant only in non-resistant patients at 5 years (P=0.041).

Conclusions

There was no definite decrease in the HBsAg level during the early period of nucleoside analogue treatment, with long-term treatment being required to observe a significant reduction.     

Microbial aetiology and sensitivity of asymptomatic bacteriuria among ante-natal mothers in Mulago hospital, Uganda

Background

Asymptomatic bacteriuria in pregnancy is associated with potential urinary and obstetric complications. However the prevalence aetiology and antimicrobial sensitivity patterns of asymptomatic bacteriurea among women attending ante-natal care in our Hospital is not known.

Objective

To determine the prevalence and identify the aetiological agents associated with assymptomatic bacteriurea in antenatal mothers in Mulago Hospital. We also intented to determine the anti-microbial sensitivity patterns of the common uropathogen in this population

Methods

We performed culture and anti-microbial sensitivity tests on urine samples from 218 consecutive ante-natal mothers in Mulago Hospital. All participants did not have any clinical symptoms attributable to urinary tract infection.

Results

Twenty nine (13.3%) of the samples had significant bacterial growth and E.coli was the commonest isolate (51.2%). There was a high level (20–62%) of anti-bacterial resistance to the commonly used antibiotics.

Conclusion

Asymptomatic bacteriuria is common among ante-natal mothers in Mulago. E. Coli that is resistant to the most commonly used antibiotics is the commonest isolate.”     

Pretreatment serum HBsAg-to-HBV DNA ratio predicts a virologic response to entecavir in chronic hepatitis B

Background/Aims

Decay of hepatitis B surface antigen (HBsAg) titers has previously been shown to be predictive of a virologic response (VR), especially during peginterferon-alpha therapy. However, the role of HBsAg levels in predicting a VR to nucleos(t)ide analog therapy has not yet been established. In this study we sought to determine whether the VR can be predicted from HBsAg titers in nucleos(t)ide-naïve chronic hepatitis B (CHB) patients treated with entecavir.

Methods

CHB patients who started entecavir as an initial antiviral therapy were enrolled in this study. Serum hepatitis B virus (HBV) DNA, HBsAg, and alanine aminotransferase levels were measured every 3 months during treatment. A VR was defined as undetectable serum HBV DNA titer by real-time PCR assay (<60 IU/mL).

Results

Fifty-two patients were enrolled, and the median duration of treatment was 26 months (range 7-35 months). Forty-five patients achieved a VR; the cumulative VR rates at 3, 6, 12, and 24 months were 40%, 71.2%, 81.5%, and 88%, respectively. Baseline HBV DNA levels were significantly lower in patients with VR, whereas the HBsAg levels did not differ significantly between patients with or without VR. In a univariate analysis the cumulative VR rate was significantly higher in HBeAg negative patients and patients with an HBsAg/HBV DNA ratio above 0.56. However, in a multivariate analysis only an HBsAg/HBV DNA ratio above 0.56 was an independent predictor of VR (P=0.003). The area under the receiver operating characteristic curve was larger for the HBsAg/HBV DNA ratio than for either HBV DNA or HBsAg.

Conclusions

Pretreatment HBsAg/HBV DNA ratio can predict a long-term VR to entecavir therapy in nucleos(t)ide-naïve CHB patients.     

Type and cause of liver disease in Korea: single-center experience, 2005-2010

Background/Aims

The aim of this study was to describe the types and causes of liver disease in patients from a single community hospital in Korea between April 2005 and May 2010.

Methods

A cohort of patients who visited the liver clinic of the hospital during the aforementioned time period were consecutively enrolled (n=6,307). Consistent diagnostic criteria for each liver disease were set by a single, experienced hepatologist, and the diagnosis of all of the enrolled patients was confirmed by retrospective review of their medical records.

Results

Among the 6,307 patients, 528 (8.4%) were classified as acute hepatitis, 3,957 (62.7%) as chronic hepatitis, 767 (12.2%) as liver cirrhosis, 509 (8.1%) as primary liver cancer, and 546 (8.7%) as a benign liver mass or other diseases. The etiologies in the acute hepatitis group in decreasing order of prevalence were hepatitis A (44.3%), toxic hepatitis (32.4%), other hepatitis viruses (13.8%), and cryptogenic hepatitis (9.1%). In the chronic hepatitis group, 51.2% of cases were attributed to viral hepatitis, 33.3% to nonalcoholic fatty liver disease, and 13.0% to alcoholic liver disease (ALD). Of the cirrhoses, 73.4% were attributable to viral causes and 18.1% to alcohol. Of the hepatocellular carcinoma cases, 86.6% were attributed to viral hepatitis and 11.6% to ALD. Among the benign tumors, hemangioma comprised 52.2% and cystic liver disease comprised 33.7%.

Conclusions

Knowledge of the current status of the type and cause of liver disease in Korea may be valuable as a basis for evaluating changing trends in liver disease in that country.     

Hepatitis B infection is highly endemic in Uganda: findings from a national serosurvey

Background

Infant immunization against hepatitis B began in Uganda in 2002.

Objective

To determine the baseline prevalence of hepatitis B virus (HBV) infection and explore risk factors.

Methods

A hepatitis B prevalence study was nested in the 2005 national HIV/AIDS serobehavioural survey. Demographic characteristics and risk factors were explored by questionnaire. One third of blood specimens (n=5875) from adults aged 15 to 59 years were tested for hepatitis B core antibodies (HBcAb); positive specimens were tested for hepatitis B surface antigen (HBsAg).

Results

HBcAb was present in 52.3% (95% CI: 51.0–53.6) of adults, and HBsAg in 10.3% (9.5–11.1). By 15–19 years of age, 40.0% had been infected with HBV. Prevalence of both markers was significantly higher across northern Uganda, in rural areas, among the poor and least educated, and in uncircumcised men. Other independent predictors of infection were age, ethnic group, occupation, number of sex partners, and HIV and HSV-2 status.

Conclusion

Hepatitis B virus infection is highly endemic in Uganda, with transmission occurring in childhood and adulthood. More than 1.4 million adults are chronically infected and some communities disproportionately affected. The hepatitis B infant immunization programme should be sustained and catch-up vaccination considered for older children.     

Comparison of HCV core antigen and anti-HCV with HCV RNA results

Background

The measurement of anti-HCV antibodies using immunological methods and the confirmation of viral nuclear acid based on molecular methods is important in diagnosis and follow-up of the HCV infection.

Objectives

In this study, we aimed to analyse HCV core Antigen positivity among anti-HCV antibody positive sera to determine the significance of testing of HCV core Ag for the laboratory diagnosis of HCV infection, by considering the correlation between serum HCV core Ag and HCV RNA levels.

Methods

115 patients suspected of having hepatitis C and who were positive for anti-HCV antibody were investigated using chemiluminescent and molecular methods. Anti-HCV antibody, HCV core Ag and HCV RNA levels were detected by the Vitros ECiQ immunodiagnostic system, Architect i2000 system and RT-PCR, respectively.

Results

The sensitivity, specificity, positive and negative predictive values and accuracy rate of HCV core Antigen assay were detected as 86.5%(83/96), 100%(19/19), 100%(83/83), 59.4%(19/32), 88.7%(102/115) respectively.

Conclusion

HCV core Ag assay could be used for diagnosis of HCV infection as it is easy to perform, cost-effective, has high specificity and positive predictive value. However, it should be kept in mind that it may have lack of sensitivity and negative predictive value.     

Prediction of compensated liver cirrhosis by ultrasonography and routine blood tests in patients with chronic viral hepatitis

Background/Aims

Liver biopsy is a standard method for diagnosis of liver cirrhosis in patients with chronic hepatitis. Because liver biopsy is an invasive method, non-invasive methods have been used for diagnosis of compensated liver cirrhosis in patients with chronic hepatitis. The current study was designed to evaluate the usefulness of ultrasonography and routine blood tests for diagnosis of compensated liver cirrhosis in patients with chronic viral hepatitis.

Methods

Two hundred three patients with chronic viral hepatitis who underwent liver biopsy were included in this study and ultrasonography and routine blood tests were analyzed retrospectively. Ultrasonographic findings, including surface nodularity, parenchyma echogenecity, and spleen size, were evaluated. The diagnostic accuracy of ultrasonography and routine blood tests were examined.

Results

Discriminant analysis with forward stepwise selection of variables showed that liver surface nodularity, platelet count, and albumin level were independently associated with compensated liver cirrhosis (p<0.05). Cross-tabulation revealed that the following 4 variables had >95% specificity: platelet count <100,000 /uL; albumin level <3.5 g/dL; INR >1.3; and surface nodularity. If at least one of the four variables exists in a patient with chronic viral hepatitis, we can predict liver cirrhosis with 90% specificity and 61% sensitivity.

Conclusions

These results suggest that four variables (platelet count <100,000 /uL, albumin level <3.5 g/dL, INR >1.3, and surface nodularity) can be used for identification of liver cirrhosis in patients with chronic viral hepatitis with high specificity.     

Effect of alcohol on the development of hepatocellular carcinoma in patients with hepatitis B virus-related cirrhosis: a cross-sectional case-control study

Background/Aims

Whether alcohol intake increases the risk of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B virus (HBV) infection remains controversial. The aim of this study was to determine the effect of alcohol intake on the development of HCC.

Methods

Between January 2006 and August 2008, 146 patients with an initial diagnosis of HCC who were hospitalized in 3 major hospitals in the Incheon area were enrolled as cases. Another 146 cirrhotic patients, who matched the cases by age and sex, were enrolled as controls. All cases and controls were HBsAg positive, and had a history of lifetime alcohol intake.

Results

The cases and controls were aged 53±8 and 53±9 years (mean±SD), respectively, with each group comprising 118 males and 28 females. The basal laboratory data, distribution of Child-Pugh class, HBeAg positivity (31.5% vs. 37.7%), HBV DNA level (5.74±2.35 vs. 5.98±2.29 log₁₀ copies/mL), and proportion with a lifetime alcohol intake of more than 292 kg (30.8% vs. 34.9%) did not differ between cases and controls. The cumulative alcohol intake and the proportion of heavy drinkers did not differ between the two groups in male patients.

Conclusions

Alcohol intake might not increase the risk of HCC in patients with HBV infection.     

Clinical features of acute viral hepatitis B in Korea: a multi-center study

Background/Aims

The incidence of Hepatitis B has significantly declined since the introduction of an HBV vaccination program. The aim of this study was to investigate recent clinical features of acute viral hepatitis B (AVH-B) in Korea.

Methods

A total of 2241 patients with acute viral hepatitis were enrolled and their data were collected from nine medical-centers between January 2006 and December 2009.

Results

One hundred nineteen (5.3%) of the 2241 were diagnosed as AVH-B. Among 78 patients with AVH-B whose data were analyzed, 50 were male, and the mean age was 38.6 years. In an initial test, mean AST, ALT and total-bilirubin levels were 1296.2 IU/L, 2109.6 IU/L and 9.3 mg/dl, respectively. Positivity frequencies for HBeAg and anti-HBe were 55.1% and 67.9%, respectively, and the mean HBV DNA level was 5.2 log10 copies/ml. The mean length of hospitalization was 11.6 days. During follow-up, AST, ALT and total bilirubin levels were normalized or near-normalized in all patients without serious complications. Sixty-three of 66 (95.4%) patients showed HBsAg loss and 37 (56.1%) patients showed HBsAg seroconversion. Only 3 patients (4.5%) showed persistent hepatitis B viremia. There was no case of death or liver transplantation. Nine patients (11.3%) had received anti-viral agents and their clinical outcomes were not significantly different from those of patients treated without antiviral agents.

Conclusions

The prevalence of AVH-B among acute hepatitis patients is relatively low in Korea. AVH-B infection can be cured without complications in almost all patients, regardless of antiviral treatment.     

Hepatitis B and HIV co-infection is still treated using lamivudine-only antiretroviral therapy combination in Uganda

Background

Hepatitis B virus (HBV) and HIV are endemic in Uganda. Co-infection is common and leads to rapid progression of liver disease. Burden of co-infection is unknown yet most patients are on lamivudine-only ART where resistance is frequent. Most patients are initiated on antiretroviral therapy (ART) without knowing their HBV status.

Objectives

To determine burden of co-infection and HBV viral suppression among patients on ART in Northern Uganda.

Methods

We recruited HIV infected adult patients on ART in a cross-sectional study. Age, sex, ART regimen and duration were recorded. Hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBcAb) and liver panel were performed. For those HBsAg+, hepatitis B e antigen (HBeAg) and HBV DNA were performed. CD4 cell count was recorded.

Results

Three hundred patients were recruited. Twenty (6.7%) were co-infected, while 41% were anti-HBcAb+. Overall 188 (62.7%) were on lamivudine- only HBV active drug. Median ART duration 2 years (IQR 1–5), mean CD4+ cell count 317 cells/microlitre (SD 255–557). Of 20 HIV/HBV co-infected, 11/20 (55%) were on lamivudine-only ART, median duration 1.5 years. Nineteen (95%) had undetectable HBV DNA. Seventeen (85%) were HBeAg negative. Mean CD4+ cell count 327 cells/microlitre (SD 197–482).

Conclusion

A large proportion of patients were on lamivudine- only HBV-active ART. Resistance may occur long term thus testing for HBV and correct ART is recommended     

The spectrum of liver diseases in HIV infected individuals at an HIV treatment clinic in Kampala, Uganda

Background

Liver diseases are common in patients with HIV due to viral hepatitis B and C co-infections, opportunistic infections or malignancies, antiretroviral drugs and drugs for opportunistic infections.

Objective

To describe the spectrum of liver diseases in HIV-infected patients attending an HIV clinic in Kampala, Uganda.

Method

Consecutive patients presenting with jaundice, right upper quadrant pain with fever or malaise, ascites and/or tender hepatomegaly were recruited and underwent investigations to evaluate the cause of their liver disease.

Results

Seventy-seven consecutive patients were recruited over an eleven month period. Of these, 23 (30%) had increased transaminases because of nevirapine (NVP) and/or isoniazid (INH) hepatotoxicity. Although 14 (61%) patients with drug-induced liver disease presented with jaundice, all recovered with drug discontinuation. Hepatitis B surface antigen was positive in 11 (15%) patients while anti-hepatitis C antibody was reactive in only 2 (3%). Probable granulomatous hepatitis due to tuberculosis was diagnosed in 7 (9%) patients and all responded to anti-TB therapy. Other diagnoses included alcoholic liver disease, AIDS cholangiopathy, hepatocellular carcinoma, schistosomiasis, haemangioma and hepatic adenoma. Twelve (16%) patients died during follow-up of which 7 (9%) died because of liver disease.

Conclusion

Drug history, liver enzyme studies, ultrasound, and hepatitis B and C investigations identified the probable etiology in 60 (78%) of 77 patients with HIV infection presenting with symptoms and/or signs of liver disease.
