AbstractThe main objective of this study is to analyze the clinical and pathological features and prognosis of patients with Hepatitis B associated membranous nephropathy (HBV-MN) and idiopathic membranous nephropathy (IMN) complicated with hepatitis B virus (HBV) infection. This study will provide more basis for diagnosis and prognosis evaluation. A total of 50 patients with HBV-MN were included in this study. 56 IMN patients complicated with HBV infection diagnosed during the same period formed the control group. Parameters including blood routine, urine routine and plasma levels of albumin (ALB), serum creatinine (SCR), blood urea nitrogen (BUN), urea acid (UA), total cholesterol (T-CHO), triglycerides (TG), complement C3 and C4, glutamic pyruvic transaminase (ALT), glutamic pyruvic transaminase (AST), 24-h urinary protein quantification (24 h-TP), renal phospholipase A2 receptor (PLA2R) and HBV related markers during the hospitalization and outpatient follow-up study period were collected for all the patients. The proportion of male patients was high in both groups. The average age of the HBV-MN group was 37.2 ± 14.187 years old, it was younger compared with the IMN group (P = 0.003). Nephrotic syndrome was the major clinical manifestation among patients. There was no significant difference between the two groups in the levels of anemia, microscopic hematuria, renal dysfunction, liver dysfunction, liver cirrhosis. The level of serum C3 and C4 in the HBV-MN group was lower compared with the IMN group (P = 0.002, P = 0.014). In the HBV-MN group, serum HBV markers were negative in 6 (12%) patients, 4 patients (8%) were positive for PLA2R in serum, and 5 patients (10%) were positive for PLA2R in renal tissue. Stronger IgG1 and C1q and weaker IgG4 staining were found in HBV-MN group renal tissues (P = 0.003, P = 0.025, and P = 0.001, respectively). There were no statistical differences compared with serum and renal PLA2R between HBV-MN and IMN groups (P = 0.098, P = 0.109). During the 1-year follow-up, there was no significant difference in complete remission rate between the two groups (P = 0.7739). Renal biopsy is crucial to diagnose HBV-MN. IgG subtypes in the HBV-MN group were mainly IgG1 deposition, while those in IMN complicated with HBV infection group were mainly IgG4 deposition. When HBV-associated antigen and PLA2R are present in renal tissue, lower level of serum C3 and C4, high intensity of renal C1q and IgG1 is more supportive of HBV-MN. The positive of PLA2R in serum and renal tissue in differentiating HBV from IMN complicated with HBV infection remains to be discussed.

Hepatitis B is a life threatening infectious liver disease caused by hepatitis B virus (HBV). The aim of this study was to determine the prevalence of HBV among food vendors in Wurukum, a highly commercial section of metropolitan Makurdi in Benue State. The test was carried out with the use of an immunochromatographic  micropoint HBsAg test strips and a HBsAg  buffer screen for the virus. Out of the 250 non-vaccinated food vendors sampled, 27(10.8%) had HBV infection, with more in males (21.7%) than in females (6.6%). No significant difference (p>0.05) was found among age groups in spite of the observed highest prevalence of 14.3% among the 20-29 year olds. Therefore, the need for routine screening cannot be overemphasized in spite of known risk factors among food vendors.

Background The prevalence of hepatitis B virus (HBV) in the Pakistani population has been reported previously, however, studies with a city-oriented approach and focus on age and gender distribution are very limited. Therefore, the current study was designed to unravel the age-wise and gender wise prevalence of HBV in Lahore, Pakistan. Methods A total of 350 blood samples of both male and female patients who visited National Genetic Laboratory, Lahore between February 2019 and July 2019 and who were suspected of HBV infection were screened. Sandwich based ELISA was used to detect rapid hepatitis B surface antigen (HbsAg) according to the manufacturer’s instruction. Real time PCR was used to detect HBV using HBV Rotor Gene PCR kit. Results Out of 350 blood samples screened for HBV infection (n= 350), 180 (51.43%) were of males and 170 (48.57%) were of females. Mean age (years) with SD (standard deviation) of the screened population was 37.22 ± 12.16 years. Overall, 224 samples (64%) were found to be positive for HBV infection. In our study, the number of females with this infection (52.24%) was slightly higher than males (47.76%). However, we observed no statistically significant difference (p = 0.225) between them. Conclusion Our study concludes that HBV is highly prevalent in Lahore, Pakistan. Females are slightly more susceptible to HBV infection as compared to males. This study also reports that HBV is more prevalent in the 20-40 age group.

A community-based seroepidemiological survey of Addis Ababa, Ethiopia was conducted in 1994 to inform on the transmission dynamics and control of hepatitis B virus (HBV) infection. Venous blood from 4736 individuals under 50 years of age from 1262 households, selected using stratified cluster-sampling, was screened for HBV markers using commercial ELISAs. HBsAg prevalence was 7% (95% CI 6–8), higher in males (9%; 7–10) than females (5%; 4–6). HBeAg prevalence in HBsAg positives was 23% (18–29), and less than 1% of women of childbearing age were HBeAg positive. Overall HBV seroprevalence (any marker), rose steadily with age to over 70% in 40–49 year olds, indicating significant childhood and adult transmission. Estimated instantaneous incidence was 3–4/100 susceptibles/year, higher in males than females in 0–4 year olds, and peaking in early childhood and young adults. The age at which 50% had evidence of infection was around 20 years, and the herd immunity threshold is approximated at 63–77%. Addis Ababa is of intermediate-high HBV endemicity, with negligible perinatal transmission. Our main findings are the identification of a significant difference between males and females in the age-acquisition of HBV infection, and marked differences between age groups in HBV incidence rates. These results should target future research studies of underlying risk factors. Furthermore, we generate a crude estimate of the level of coverage of HBV vaccine that would be required to eliminate the virus from the study population.

Abstract BackgroundCryoglobulinemic glomerulonephritis (CryoGn) caused by hepatitis B virus (HBV) infection was rarely reported. Our study aimed to investigate the clinical features, renal pathology findings, and prognosis in patients with HBV related CryoGn. Methods This was a retrospective study including seven Chinese patients with HBV related CryoGn in a tertiary referral hospital from April 2016 to March 2019. The clinical and pathological data were collected and analyzed.Results Age at renal biopsy was 47±12 years, with female/male ration 3/4. Urine protein was 5.6(3.0, 6.6) g/d and five cases presented with nephrotic syndrome. The baseline eGFR was 23.5 (20.2, 46.3) ml/min per 1.73m2. The extrarenal manifestations included purpura (n=6), arthralgia (n=1), peripheral neuropathy (n=1), and cardiomyopathy (n=1). Six cases had type II cryoglobulinemia with IgMκ, the other one had type III. The median cryocrit was 4.0 (1.0, 15.0) %. Renal pathologic findings on light microscopy: endocapillary proliferative glomerulonephritis (Gn) (n=3), membranoproliferative Gn (n=3), and mesangial proliferative Gn (n=1). On immunofluorescence microscopy, the predominant type of immunoglobulin deposits was IgM(n=5). HBsAg and HBcAg deposits were found in one case. Ultrastructural studies showed granular subendothelial and mesangial electron-dense deposits in all patients and microtubules in one case. All patients received antiviral medications. They were given corticosteroid alone (n=2) or combined with cyclophosphamide (n=4) or mycophenolate mofetil (n=1). Two patients received plasmapheresis. The median follow-up time was 18 (6, 37) months. Four patients got remission, two patients died of pneumonia, and one progressed to end-stage renal disease (ESRD). At endpoint of follow-up, 24hUP was 2.1 (0.8-5.2) g/d, and eGFR was 55.3 (20.7, 111.8) ml/min per 1.73m2. The median cryocrit decreased to 1.0 (0, 5.75) %.ConclusionsThe etiology of mixed CryoGn should be screened for HBV infection. Endocapillary proliferative Gn and membranoproliferative Gn were the common pathologic patterns. Diagnosis and treatment in early-stage benefit patients’ renal outcomes. Immunosuppressive therapy should be considered for severe renal disease, based on efficient antiviral therapy.

Objective.To determine the significance of hepatitis B virus (HBV)-associated antigen deposition in renal tissue from patients with systemic lupus erythematosus (SLE).Methods.The medical records of 166 inpatients with lupus nephritis and 384 controls without SLE were analyzed retrospectively. Patients with SLE were classified as positive or negative depending on whether HBV-associated antigen deposition was detected in renal biopsies.Results.HBV-associated antigen deposition was mainly detected in renal tissue from patients with SLE (50.6%), primary renal glomerular disease (20.8%), and allergic purpura (21.7%). It was not detected in renal tissue from patients with diabetic nephropathy, hypertensive nephrosclerosis, thin basement membrane nephropathy, or Alport syndrome. Hepatitis B surface antigen and core antigen were deposited in the mesangial region and vascular loops. The positive group had a significantly higher frequency of IgG, IgA, and IgM deposition than the negative group (53.6% vs 30.5%; p < 0.01). There was no significant difference in the types of lupus nephritis observed between the 2 groups.Conclusion.There was a high prevalence of HBV-associated antigen deposition in renal tissue of patients with SLE by indirect immunofluorescence, which may result mainly from the cross-reactivity with deposited immunoglobulins.

ABSTRACTAimCurrent clinical recommendations suggest treating chronic hepatitis B virus (HBV) infection in a minority of cases, but more data are needed to determine the benefits and risks of Tenofovir disoproxil fumarate (TDF) therapy. We aimed to assess the impact of TDF on liver disease, and the risk of nephrotoxicity.MethodWe studied a longitudinal UK chronic HBV (CHB) cohort attending out-patient clinics between 2005 and 2018, analysing data for 206 ethnically diverse adults (60 on TDF, 146 untreated), with median follow-up 3.3±2.8 years.ResultsPatients prescribed TDF were older (39 vs. 35 years, p=0.004) with a male excess (63% vs. 47%, p=0.04) compared to untreated patients. Reflecting treatment eligibility criteria, at baseline, treated patients were more likely to have elevated ALT (p<0.001), higher HBV DNA viral load (VL) (p<0.001), and higher elastography scores (p=0.002), but with no difference in renal function (p=0.6). In the TDF group, VL declined significantly between baseline and subsequent time points (all p<0.0001) with VL suppressed in 94% at three years, while in the untreated group viraemia was unchanged from baseline. In the TDF group, ALT and elastography scores normalised during treatment and by three years were equivalent to those in the untreated group. Progression of liver fibrosis did not occur in the TDF group but arose in 7.4% of untreated patients, although this difference was non-significant. There was no significant difference in renal impairment during follow-up between two groups.ConclusionTDF may have long-term benefits for a wider pool of the CHB population.

Abstract Background and Aims To describe the clinical features, renal pathology findings and prognosis in patients with mixed cryoglobulinemic glomerulonephritis (Gn) caused by hepatitis B virus (HBV) infection. Method This was a retrospective study including seven Chinese patients with HBV infection associated mixed cryoglobulinemic Gn in a tertiary referral hospital from April, 2016 to March, 2019. The demographic, clinical, pathological characteristics, treatment and follow-up data were collected and analyzed. Results Age at renal biopsy was 47±12 years, including three females and four males. 24hUP was 5.6(3.0, 6.6)g/d and five cases presented with nephrotic syndrome. The median baseline eGFR(CKD-EPI) was 23.5(20.2, 46.3) ml/min per 1.73m2. The extrarenal manifestations were: purpura (n=6), arthralgia (n=1), peripheral neuropathy (n=1), and cardiomyopathy (n=1). Six cases had type II cryoglobulinemia with IgMκ, the other one had type III. The median cryocrit was 4.0 (1.0, 15.0) %, rheumatoid factor was 368(117, 733) IU/ml, C3 was 0.48(0.41, 0.57) g/L, C4 was 0.013(0.003, 0.118) g/L. Renal pathologic findings on light microscopy: endocapillary proliferative Gn (n=3), membranoproliferative Gn (n=3), and mesangial proliferative glomerulonephritis(n=1). Hyaline thrombi were seen in four cases, while crescents were found in two cases. On immunofluorescence microscopy, the predominant types of immunoglobulin deposits were: IgM(n=5), IgA(n=1), and codominance of IgG and IgA(n=1). HBsAg and HBcAg deposits were found in only one case. Ultrastructural studies showed granular subendothelial and mesangial electron-dense deposits in all patients and organized microtubules was seen in only one case. All patients received antiviral medication (entecavir, n=6; lamivudine, n=1). They were given corticosteroid alone(n=2) or combined with cyclophosphamide(n=4) or mycophenolate mofetil(n=1). Two patients received plasmapheresis. The median follow-up time were 18 (6, 37) months. One patient died from pneumonia, and one progressed to end stage of renal disease (ESRD). At endpoint of follow-up, 24hUP was 2.1 (0.8-5.2) g/d, and eGFR (CKD-EPI) was 55.3 (20.7, 111.8) ml/min per 1.73m2. Conclusion Mixed cryoglobulinemic Gn should be screened for HBV etiologies, especially in HBV-endemic country. Endocapillary proliferative Gn was the common pathologic type, as well as membranoproliferative Gn. Diagnosis and treatment in early stage benefit patients’ renal outcome. Long-term prognosis should be investigated in further studies.

Objective To determine whether genetic polymorphisms in the uridine diphosphate-glucuronosyltransferase 1A ( UGT1A) and the C-C motif chemokine receptor 5 ( CCR5) genes are associated with hepatitis B virus (HBV) infection in Yi, Yao and Han ethnic groups in the Guizhou Province of China. Methods The study enrolled subjects with and without HBV infection. Whole blood was used for DNA genotyping using standard techniques. The study determined the frequencies of several polymorphic alleles ( UGT1A6 [rs2070959], UGT1A1 [rs8175347], CCR5-59029 [rs1799987] and CCR5Δ32 [rs333]) and then characterized their relationship with HBV infection. Results A total of 404 subjects were enrolled in the study: 138 from the Yao group, 101 from the Yi group and 165 from the Han group. There was a significant difference in the frequency of UGT1A1 rs8175347 polymorphisms among the three groups. The rates of 7TA carriers of UGT1A1 rs8175347 in all three groups were significantly higher than the other genotypes. Individuals with genotype AA of UGT1A6 rs2070959 in the Yi group had a higher risk for HBV infection than in the Yao and Han groups. The frequency of genotype GG in CCR5-59029 in the Yao group was significantly higher than in the Yi group. The genotypes of CCR5Δ32 were not associated with HBV infection. Conclusion These findings provide genetic and epidemiological evidence for an association of UGT1A and CCR5-59029 polymorphisms with HBV infection in Chinese Yi and Yao populations.
