Urra JM, Castro P, Jiménez N, Moral E, Vozmediano C. Partial recovery of SARS-CoV-2 immunity after booster vaccination in renal transplant recipients. CLINICAL IMMUNOLOGY COMMUNICATIONS 2023; 3:1-5. [PMID: 38014395 PMCID: PMC9741556 DOI: 10.1016/j.clicom.2022.12.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 11/24/2022] [Accepted: 12/10/2022] [Indexed: 12/14/2022]
Abstract
The pandemic caused by the SARS-CoV-2 coronavirus has been especially detrimental to patients with end-stage renal disease. History with other vaccines suggests that patients with renal disease may not respond adequately to the SARS-CoV-2 vaccine. The aim of this study is to evaluate the immunity to SARS-CoV-2 mRNA vaccines in renal patients. Post SARS-CoV-2 vaccination first, and after the booster dose, antibodies and cellular immunity were studied in patients on hemodialysis (N = 20), peritoneal dialysis (N = 10) and renal transplantation (N = 10). After the two doses of vaccine, there was an effective immunity in dialysis patients, with 100% seroconversion and 87% detection of cellular immunity (85% in hemodialysis and 90% in peritoneal dialysis). In contrast, in renal transplant recipients there was only 50% seroconversion and cellular immunity was detected in 30% of patients. After the booster dose, all dialysis patients achieved a cellular and antibody immunity, whereas in transplant patients, despite improvement, 20% did not produce antibodies and in 37.5% cellular immunity could not be detected. The mRNA vaccine plus booster performs excellently in dialysis patients, whereas in kidney transplant recipients, despite the booster, complete immunization is not achieved.

[PMID: 36803903 PMCID: PMC10065969 DOI: 10.1016/j.vaccine.2023.02.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Revised: 12/24/2022] [Accepted: 02/03/2023] [Indexed: 02/21/2023]
Abstract
BACKGROUND This scoping review summarizes a key aspect of vaccinomics by collating known associations between heterogeneity in human genetics and vaccine immunogenicity and safety. METHODS We searched PubMed for articles in English using terms covering vaccines routinely recommended to the general US population, their effects, and genetics/genomics. Included studies were controlled and demonstrated statistically significant associations with vaccine immunogenicity or safety. Studies of Pandemrix®, an influenza vaccine previously used in Europe, were also included, due to its widely publicized genetically mediated association with narcolepsy. FINDINGS Of the 2,300 articles manually screened, 214 were included for data extraction. Six included articles examined genetic influences on vaccine safety; the rest examined vaccine immunogenicity. Hepatitis B vaccine immunogenicity was reported in 92 articles and associated with 277 genetic determinants across 117 genes. Thirty-three articles identified 291 genetic determinants across 118 genes associated with measles vaccine immunogenicity, 22 articles identified 311 genetic determinants across 110 genes associated with rubella vaccine immunogenicity, and 25 articles identified 48 genetic determinants across 34 genes associated with influenza vaccine immunogenicity. Other vaccines had fewer than 10 studies each identifying genetic determinants of their immunogenicity. Genetic associations were reported with 4 adverse events following influenza vaccination (narcolepsy, GBS, GCA/PMR, high temperature) and 2 adverse events following measles vaccination (fever, febrile seizure). CONCLUSION This scoping review identified numerous genetic associations with vaccine immunogenicity and several genetic associations with vaccine safety. Most associations were only reported in one study. This illustrates both the potential of and need for investment in vaccinomics. Current research in this field is focused on systems and genetic-based studies designed to identify risk signatures for serious vaccine reactions or diminished vaccine immunogenicity. Such research could bolster our ability to develop safer and more effective vaccines.

Influence of age, gender, previous SARS-CoV-2 infection, and pre-existing diseases in antibody response after COVID-19 vaccination: A review. Mol Immunol 2023; 156:148-155. [PMID: 36921489 PMCID: PMC9998295 DOI: 10.1016/j.molimm.2023.03.007] [Citation(s) in RCA: 15] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 01/27/2023] [Accepted: 03/07/2023] [Indexed: 03/12/2023]
Abstract
Vaccines induce specific long-term immunological memory against pathogens, preventing the worsening of diseases. The COVID-19 health emergency has caused more than 6 million deaths and started a race for vaccine development. Antibody response to COVID-19 vaccines has been investigated primarily in healthcare workers. The heterogeneity of immune responses and the behavior of this response in particular groups were still very little explored. In this review, we discuss whether antibody responses after vaccination are influenced by age, gender, previous SARS-CoV-2 infection, or pre-existing diseases.

Humoral Response in Hemodialysis Patients Following COVID-19 Vaccination and Breakthrough Infections during Delta and Omicron Variant Predominance. Vaccines (Basel) 2022; 10:vaccines10040498. [PMID: 35455248 PMCID: PMC9028840 DOI: 10.3390/vaccines10040498] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2022] [Revised: 03/19/2022] [Accepted: 03/22/2022] [Indexed: 11/16/2022] Open
Abstract
Background: The advancement of COVID-19 vaccination programs globally has been viewed as an integral strategy to reduce both the number of COVID-19 cases and consequential complications of COVID-19, particularly for high-risk patient groups. There are limited data on the antibody response and protection from disease infection and severity in patients requiring hemodialysis (HD) following COVID-19 vaccination during the Delta and Omicron variant predominance. We conducted a study aiming to evaluate humoral immunity derived from two different COVID-19 vaccines administered to our in-centre HD population and investigated the characteristics of breakthrough COVID-19 infections occurring post-vaccination within this population. Methods: This is a prospective observational study including patients receiving HD at Salford Royal Hospital. The first and second doses of COVID-19 vaccinations (Pfizer BioNTech BNT162b2 or Oxford AstraZeneca ChAdOx1 nCoV-19) were administered to this patient cohort since January 2021. The incidence of any breakthrough COVID-19 infections occurring in double vaccinated patients between 1 April 2021 and 15 January 2022 was recorded. Patients were screened weekly with nasal and pharyngeal nasopharyngeal swabs for real-time Reverse Transcription Polymerase Chain Reaction (rRT-PCR) for COVID-19, whilst SARS-CoV-2 antibody testing was performed alongside monthly routine HD bloods. Results: Four hundred eleven patients receiving HD were included in this study, of which 170 of 178 patients (95.5%) with available data on antibody status following two doses of the Pfizer BioNTech BNT162b2 vaccination had detectable antibody response, whilst this was the case for 97 of 101 patients (96.1%) who received two doses of the Oxford AstraZeneca ChAdOx1 nCoV-19 vaccine. For 12 seronegative patients who received a booster vaccine (third dose), nine seroconverted, while one remained negative and two were not tested. No statistically significant differences were observed with regards to antibody status between those receiving Pfizer BioNTech BNT162b2 and Oxford AstraZeneca ChAdOx1 nCoV-19 vaccines. Sixty-three of 353 patients with two doses of COVID-19 vaccination had breakthrough COVID-19 infection (40 during Delta and 23 during Omicron variant predominance). Of the 40 patients during the delta period, five were admitted into hospital and there were two reported deaths due to COVID-19-related illness. There were no COVID-19 associated hospitalizations or deaths during the Omicron variant predominance. Conclusions: The vast majority of HD patients who received two doses of the Pfizer BioNTech BNT162b2 or Oxford AstraZeneca ChAdOx1 nCoV-19 vaccinations developed detectable antibody responses. Our results support the value of booster vaccination with mRNA-based COVID-19 vaccine in HD patients and highlight the need for ongoing surveillance programmes with rRT-PCR and antibody testing for timely detection of positive cases.

Abstract
Hepatitis is defined as inflammation of the liver and is commonly due to infection with The hepatotropic viruses - hepatitis A, B, C, D and E. Hepatitis carries one of the highest disease burdens globally and has caused significant morbidity and mortality among different patient populations. Clinical presentation varies from asymptomatic or acute flu-like illness to acute liver failure or chronic liver disease, characterized by jaundice, hepatomegaly and ascites among many other signs. Eventually, this can lead to fibrosis (cirrhosis) of the liver parenchyma and carries a risk of development into hepatocellular carcinoma. Hepatitis B and C are most notorious for causing liver cirrhosis; in 2019, an estimated 296 million people worldwide had chronic hepatitis B infection and 58 million are currently estimated to have chronic hepatitis C, with 1.5 million new infections of both hepatitis B and C, occurring annually. With the help of latest serological biomarkers and viral nucleic acid amplification tests, it has become rather simple to efficiently screen, diagnose and monitor patients with hepatitis, and to commence with appropriate antiviral treatment. More importantly, the development of vaccinations against some of these viruses has greatly helped to curb the infection rates. Whilst there has been exceptional progress over the years in the management of viral hepatitis, many hurdles still remain which must be addressed in order to proceed towards a hepatitis-free world. This review will shed light on the origin and discovery of the hepatitis viruses, the global epidemiology and clinical symptoms, diagnostic modalities, currently available treatment options, the importance of prevention, and the journey needed to move forward towards the eradication of its global disease burden.

Abstract
BACKGROUND Whether breakthrough SARS-CoV-2 infections after vaccination are related to the level of postvaccine circulating antibody is unclear. OBJECTIVE To determine longitudinal antibody-based response and risk for breakthrough infection after SARS-CoV-2 vaccination. DESIGN Prospective study. SETTING Nationwide sample from dialysis facilities. PATIENTS 4791 patients receiving dialysis. MEASUREMENTS Remainder plasma from a laboratory processing routine monthly tests was used to measure qualitative and semiquantitative antibodies to the receptor-binding domain (RBD) of SARS-CoV-2. To evaluate whether peak or prebreakthrough RBD values were associated with breakthrough infection, a nested case-control analysis matched each breakthrough case patient to 5 control patients by age, sex, and vaccination month and adjusted for diabetes status and region of residence. RESULTS Of the 4791 patients followed with monthly RBD assays, 2563 were vaccinated as of 14 September 2021. Among the vaccinated patients, the estimated proportion with an undetectable RBD response increased from 6.6% (95% CI, 5.5% to 7.8%) 14 to 30 days after vaccination to 20.2% (CI, 17.0% to 23.3%) 5 to 6 months after vaccination. Estimated median index values decreased from 91.9 (CI, 78.6 to 105.2) 14 to 30 days after vaccination to 8.4 (CI, 7.6 to 9.3) 5 to 6 months after vaccination. Breakthrough infections occurred in 56 patients, with samples collected a median of 21 days before breakthrough infection. Compared with prebreakthrough index RBD values of 23 or higher (equivalent to ≥506 binding antibody units per milliliter), prebreakthrough RBD values less than 10 and values from 10 to less than 23 were associated with higher odds for breakthrough infection (rate ratios, 11.6 [CI, 3.4 to 39.5] and 6.0 [CI, 1.5 to 23.6], respectively). LIMITATIONS Single measure of vaccine response; ascertainment of COVID-19 diagnosis from electronic health records. CONCLUSION The antibody response to SARS-CoV-2 vaccination wanes rapidly in persons receiving dialysis. In this population, the circulating antibody response is associated with risk for breakthrough infection. PRIMARY FUNDING SOURCE Ascend Clinical Laboratory.

Abstract
Kidney disease is a known risk factor for poor outcomes of COVID-19 and many other serious infections. Conversely, infection is the second most common cause of death in patients with kidney disease. However, little is known about the underlying secondary immunodeficiency related to kidney disease (SIDKD). In contrast to cardiovascular disease related to kidney disease, which has triggered countless epidemiologic, clinical, and experimental research activities or interventional trials, investments in tracing, understanding, and therapeutically targeting SIDKD have been sparse. As a call for more awareness of SIDKD as an imminent unmet medical need that requires rigorous research activities at all levels, we review the epidemiology of SIDKD and the numerous aspects of the abnormal immunophenotype of patients with kidney disease. We propose a definition of SIDKD and discuss the pathogenic mechanisms of SIDKD known thus far, including more recent insights into the unexpected immunoregulatory roles of elevated levels of FGF23 and hyperuricemia and shifts in the secretome of the intestinal microbiota in kidney disease. As an ultimate goal, we should aim to develop therapeutics that can reduce mortality due to infections in patients with kidney disease by normalizing host defense to pathogens and immune responses to vaccines.

Abstract
BACKGROUND Patients receiving dialysis are a sentinel population for groups at high risk for death and disability from COVID-19. Understanding correlates of protection post-vaccination can inform immunization and mitigation strategies. METHODS Monthly since January 2021, we tested plasma from 4791 patients receiving dialysis for antibodies to the receptor-binding domain (RBD) of SARS-CoV-2 using a high-throughput assay. We qualitatively assessed the proportion without a detectable RBD response and among those with a response, semiquantitative median IgG index values. Using a nested case-control design, we matched each breakthrough case to five controls by age, sex, and vaccination-month to determine whether peak and pre-breakthrough RBD IgG index values were associated with risk for infection post-vaccination. RESULTS Among 2563 vaccinated patients, the proportion without a detectable RBD response increased from 6.6% [95% CI 5.5-8.1] in 14-30 days post-vaccination to 20.2% [95% CI 17.1-23.8], and median index values declined from 92.7 (95% CI 77.8-107.5) to 3.7 (95% CI 3.1-4.3) after 5 months. Persons with SARS-CoV-2 infection prior-to-vaccination had higher peak index values than persons without prior infection, but values equalized by 5 months (p=0.230). Breakthrough infections occurred in 56 patients, with samples collected a median of 21 days pre-breakthrough. Peak and pre-breakthrough RBD values <23 (equivalent to <506 WHO BAU/mL) were associated with higher odds for breakthrough infection (OR: 3.7 [95% CI 2.0-6.8] and 9.8 [95% CI 2.9-32.8], respectively). CONCLUSIONS The antibody response to SARS-CoV-2 vaccination wanes rapidly, and in persons receiving dialysis, the persisting antibody response is associated with risk for breakthrough infection.

Abstract
BACKGROUND Assessing the evolution of SARS-CoV-2 immune response among patients receiving dialysis can define its durability in a highly clinically relevant context because patients receiving dialysis share the characteristics of persons most susceptible to SARS-CoV-2 infection. OBJECTIVE To evaluate the persistence of SARS-CoV-2 receptor-binding domain (RBD) IgG in seroprevalent patients receiving dialysis. DESIGN Prospective. SETTING Nationwide sample from dialysis facilities. PATIENTS 2215 patients receiving dialysis who had evidence of SARS-CoV-2 infection as of July 2020. MEASUREMENTS Remainder plasma from routine monthly laboratories was used to measure semiquantitative RBD IgG index value over 6 months. RESULTS A total of 2063 (93%) seroprevalent patients reached an assay detectable response (IgG index value ≥1). Most (n = 1323, 60%) had responses in July with index values classified as high (IgG ≥10); 1003 (76%) remained within this stratum. Adjusted median index values declined slowly but continuously (July vs. December values were 21 vs. 13; P < 0.001). The trajectory of the response did not vary by age group, sex, race/ethnicity, or diabetes status. Patients without an assay detectable response (n = 137) were more likely to be White and in the younger (18 to 44 years) or older (≥80 years) age groups and less likely to have diabetes and hypoalbuminemia. LIMITATION Lack of data on symptoms or reverse transcriptase polymerase chain reaction diagnosis, cohort of persons who survived infection, and use of a semiquantitative assay. CONCLUSION Despite impaired immunity, most seropositive patients receiving dialysis maintained RBD antibody levels over 6 months. A slow and continual decline in median antibody levels over time was seen, but no indication that subgroups with impaired immunity had a shorter-lived humoral response was found.

Abstract
Background Patients receiving dialysis may mount impaired responses to COVID19 vaccination. Methods We report antibody response to vaccination from 1140 patients without, and 493 patients with pre-vaccination SARS-CoV-2 RBD antibody. We used commercially available assays (Siemens) to test remainder plasma monthly in association with vaccination date and type, and assess prevalence of absent total receptor binding antibody, and absent or attenuated (index value < 10) semiquantitative receptor binding domain IgG index values. We used Poisson regression to evaluate risk factors for absent or attenuated response to vaccination. Results Among patients who were seronegative versus seropositive before vaccination, 62% and 56% were ≥65 years old, 20% and 24% were Hispanic, and 22% and 23% were Black. Median IgG index values rose steadily over time, and were higher among the seropositive than in the seronegative patients after completing vaccination (150 [25th, 75th percentile 23.2, 150.0] versus 41.6 [11.3, 150.0]). Among 610 patients who completed vaccination (assessed ≥14 days later, median 29 days later), the prevalence of absent total RBD response, and absent and attenuated semiquantitative IgG response was 4.4% (95% CI 3.1, 6.4%), 3.4% (2.4, 5.2%), and 14.3% (11.7, 17.3%) respectively. Risk factors for absent or attenuated response included longer vintage of end-stage kidney disease, and lower pre-vaccination serum albumin. Conclusions More than one in five patients receiving dialysis had evidence of an attenuated immune response to COVID19 vaccination.

Laboratory correlates of SARS-CoV-2 seropositivity in a nationwide sample of patients on dialysis in the U.S. PLoS One 2021; 16:e0249466. [PMID: 33857168 PMCID: PMC8049224 DOI: 10.1371/journal.pone.0249466] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Accepted: 03/18/2021] [Indexed: 12/03/2022] Open
Abstract
Patients on dialysis are at high risk for death due to COVID-19, yet a significant proportion do survive as evidenced by presence of SARS-CoV-2 antibodies in 8% of patients in the U.S. in July 2020. It is unclear whether patients with seropositivity represent the subgroup with robust health status, who would be more likely to mount a durable antibody response. Using data from a July 2020 sample of 28,503 patients receiving dialysis, we evaluated the cross-sectional association of SARS-CoV-2 seropositivity with laboratory surrogates of patient health. In separate logistic regression models, we assessed the association of SARS-CoV-2 seropositivity with seven laboratory-based covariates (albumin, creatinine, hemoglobin, sodium, potassium, phosphate, and parathyroid hormone), across the entire range of the laboratory and in comparison to a referent value. Models accounted for age, sex, region, race and ethnicity, and county-level COVID-19 deaths per 100,000. Odds of seropositivity for albumin 3 and 3.5 g/dL were 2.1 (95% CI 1.9-2.3) and 1.3 (1.2-1.4) respectively, compared with 4 g/dL. Odds of seropositivity for serum creatinine 5 and 8 mg/dL were 1.8 (1.6-2.0) and 1.3 (1.2-1.4) respectively, compared with 12.5 mg/dL. Lower values of hemoglobin, sodium, potassium, phosphate, and parathyroid hormone were associated with higher odds of seropositivity. Laboratory values associated with poorer health status and higher risk for mortality were also associated with higher likelihood of SARS-CoV-2 antibodies in patients receiving dialysis.

Abstract
The Advisory Committee on Immunization Practices to the US Centers for Disease Control and Prevention provides annual recommendations for routine adult immunizations. Many recommendations consider patient factors such as age, medical conditions, and medications that increase an individual's risk for infection with a vaccine-preventable disease. These factors, particularly those that lead to immunocompromise, may also alter the risk-benefit ratio for live vaccines, and/or lead to decreased vaccine immunogenicity and effectiveness. The provider may need to consider alternative vaccination strategies, including higher antigen dose vaccines, adjuvanted vaccines, avoidance of live vaccines, and careful timing of vaccination to optimize safety and effectiveness in immunocompromised populations. This thematic review discusses general principles regarding immunization of adults across the spectrum of immunocompromise, examines current guidelines and studies that support them, and outlines future research needs.

Abstract
Introduction Because of the cost, in the hemodialysis centers of Kinshasa, the double dose of hepatitis B (HBV) vaccine is administered only to HIV infected patients while other patients receive a single dose. This study aimed to evaluate the single-dose vaccination Protocol and identify determinants of seroconversion's lack of anti-HBs after vaccination schedule. Methods 56 non-HIV chronic hemodialysis patients serologically negative for HBs Ag, anti-HBs and anti-HBc were selected between January 2014 and December 2016. The recombinant DNA vaccine (Euvax B®20 μg) was administered intramuscularly in the deltoid muscle at days 0, 30, 60 and 180. Serum anti-HBs titer was assayed at day 240. The endpoint was seroconversion, defined as anti-HBs titer ≥ 10 IU/l (10-99 IU/l = low protective vaccine response; ≥ 100 IU/l = highly protective vaccine response). Anti-HBs titer < 10 IU/l defined a lack of seroconversion. A Logistic regression model was used to identify factors associated with the lack of seroconversion. Results In the study group (mean age 55.6± 15.1 years; 73 % men, 36% diabetic and 86% hypertensive), low and highly protective vaccine responses were seen in 32% and 50% respectively versus 18% of patient had a lack of seroconversion. CRP > 6 mg/L (aOR: 8.96), hypoalbuminemia (aOR: 6.50) and KT/V < 1.2 (aOR: 3.70) were associated with the lack of seroconversion. Conclusion Half of the patients in the study had either a lack or low protective vaccine response. Patient-related factors and hemodialysis parameters were the main factors associated with the lack of anti-HbS seroconversion. These results highlight the need to maximize doses of vaccine in all patients.

Abstract
BACKGROUND In hemodialysis patients Hepatitis B virus (HBV) infection is one of the problems. Because of HBV vaccine response is lower than in the general population, in this study it is aimed to determine the factors that may cause inadequate HBV vaccine response in hemodialysis patients. METHODS In study, HBsAg, anti-HBs, anti-HBc IgG data belonging to 278 patients were obtained from file and computer records. It was seen that seronegative cases had been given recombinant HBV vaccine. Anti-HBs titers were monitored 1 month after vaccination was completed. According to this, the patients are divided into two groups. Those with anti-HBs < 10 IU/mL were identified as non-responders and with anti-HBs ≥ 10 IU/mL as responders. Factors such as age, serum albumin and urea reduction rate which may affect inadequate response to HBV vaccine were evaluated. As statistical examination, Chi-square test was used for the analysis of the data determined by counting, and logistic regression was used for statistically significant independent variables in chi-square test. p value of < 0.05 was considered statistically significant (Confidence interval: 95%). RESULTS Out of 278 patients, according to exclusion criteria 81 patients were excluded. 13.2%(26/197) of HBV vaccinated patients had insufficient response. The inadequate response rate to HBV vaccination was found to be higher in patients with age ≥ 65 (p = 0.039), serum albumin < 3.5 g/dL (p = 0.024) and urea reduction rate ≤ 65 (p = 0.028). No statistically significant relationship was found between inadequate response to HBV vaccine and anti-HCV positivity, presence of diabetes mellitus, anemia status, vitamin D therapy and vascular access pathway variability. CONCLUSION We conclude that relatively high patient age, low albumin level and insufficient urea reduction rate may cause inadequate HBV vaccine response. Taking these factors into consideration may provide a useful insight for an adequate response to vaccination.

Abstract
Background: Hemodialysis (HD) patients are at an increased risk of acquiring hepatitis B virus (HBV) infection. Active HBV immunization in these patients is recommended. A response rate in HD patients is variable but generally lower than healthy individuals. Objective: The aim of this study is to assess the response of HD patients to the HBV vaccine and correlate response and long-term immunity to various clinical and biomedical factors. Patients and Methods: One hundred and one patients, with a mean age 48.7 ± 18.5 years, received 40 μg of HBV vaccine administered intramuscularly in the deltoid region at 0, 1, 2 and 6 months. The patients' responses to the vaccine were determined by measuring hepatitis B surface antibody (HBsAb) 6 weeks after the last injection and monitored thereafter at 3-month intervals. Results: Seventy-one patients (70.3%) mounted a response with HBsAb >10 mIU/ml 6 weeks following the fourth dose of vaccine, and thus were considered considered as adequate responders. Forty-nine (48.5%) patients mounted an excellent response with HBsAb >100 mIU/ml 6 weeks after the fourth dose. Thirty patients (29.7%) were nonresponders. Responders were significantly younger than nonresponders (P = 0.01). Gender, hemoglobin level, serum albumin, ferritin, parathyroid hormone level and hepatitis C virus infection had no effect on the response to the vaccine. Similarly, there was no difference in diabetic state and adequacy of HD between the two groups. Fifty-nine patients (88%) had persistent protective antibodies at 1 year, while eight (12%) lost such protection. Predictors of persistent immunity at 1 year were high HBsAb level at the completion of the vaccination regime and, to a lesser extent, young age. Conclusion: A 70% response rate to HBV vaccine was observed in the cohort of this study. Young age predicts a favorable response to HBV vaccine in HD patients. High (>100 mIU/ml) HBsAb levels achieved at vaccine completion predict persistent immunity at 1 year.

Abstract
We undertook this study to assess the response of hepatitis B vaccination in dialysis patients and the effect of vitamin D level on the immunogenicity to hepatitis B vaccination. It was an observational study, which included 60 patients of end-stage renal disease on maintenance dialysis. Patients with anti-HBs antibody positive at baseline were excluded. All received intramuscular recombinant hepatitis B vaccination at 0, 1, 2, and 6 months 20 μg on each deltoid muscle bilateral. Anti-HBs antibody titers were measured at 4 and 7 months of vaccination and the titer ≥10 mIU/mL was considered as "positive". Vitamin D levels were measured at baseline before starting the vaccination. The mean vitamin D level was 15.0 ± 7.8 ng/mL. The vitamin D level <10 and <20 were 23.3% and 83.3%, respectively. The patients on hemodialysis had relatively higher vitamin D level than on peritoneal dialysis patients, i.e. 16.3 ± 8.5 and 11.5 ± 3.1 ng/mL, respectively (p = 0.03). Overall, 38 patients responded to the immunization (63.3%) and 11 patients were non-responders (36.7%) at 4 months. Difference of vitamin D level in responder (16.6 ± 9.1 ng/mL) and non-responder (12.4 ± 4.1 ng/mL) was not significant (p = 0.16). At 7 months (1 month after completion of vaccination) 61.9% were responders and 38.1% were non-responders. The vitamin D level in responders and non-responders were statistically not significant (p = 0.11). In responder, titer ≥100 mIU/mL was seen in 30% at 4 months and in 42.9% at 7 months (p = 0.05). In the good and weak responders at 7 months, vitamin D levels were 21.5 ± 10.8 and 10.1 ± 3.7 ng/mL, respectively (p = 0.37). The association of vitamin D level and anti-HBs antibody titer were not significant (r = 0.03 and 95% CI was -0.43 to 0.48, p = 0.89) in those who responded. Most patients on dialysis were vitamin D deficient. Vitamin D levels did not differ between responding and non-responding dialysis patients.

Abstract
Hepatitis outbreaks in hemodialysis (HD) patients and staff were reported in the late 1960s, and a number of hepatotropic viruses transmitted by blood and other body fluids have been identified. Hepatitis B virus (HBV) was the first significant hepatotropic virus to be identified in HD centers. HBV infection has been effectively controlled by active vaccination, screening of blood donors, the use of erythropoietin and segregation of HBV carriers. Hepatitis delta virus is a defective virus that can only infect HBV-positive individuals. Hepatitis C virus (HCV) is the most significant cause of non-A, non-B hepatitis and is mainly transmitted by blood transfusion. The introduction in 1990 of routine screening of blood donors for HCV contributed significantly to the control of HCV transmission. An effective HCV vaccine remains an unsolved challenge; however, pegylation of interferon-alfa has made it possible to treat HCV-positive dialysis patients. Unexplained sporadic outbreaks of hepatitis by the mid-1990s prompted the discovery of hepatitis G virus, hepatitis GB virus C and the TT virus. The vigilant observation of guidelines on universal precaution and regular virologic testing are the cornerstones of the effective control of chronic hepatitis in the setting of HD. Major recent advances in the viral diagnosis technology and the development of new oral, direct-acting antiviral agents allow early diagnosis and better therapeutic response. The current update will review the recent developments, controversies and new treatment of viral hepatitis in HD patients.

Abstract
Background Hemodialysis patients are exposed to blood and blood products more than the general population and are also at higher risk for hepatitis B (HB) contamination. For these reasons, it is highly recommended that this patient population gets the HB vaccine. The efficacy of the vaccine is measured by measuring titers of antibody in the serum of the patient. A minimum titer of 10 mIU/mL is considered to be a response. The conversion rate in hemodialysis patients ranges from 50% to 80%, as compared to the general population where the conversion rate is over 95%. As opposed to the general population, end-stage renal patients on hemodialysis do not always respond to the vaccine. The main objective in this study was to try to identify factors that may hinder the response. Correction of these factors in the future may help non-responders. Methods This was a retrospective chart review at a single hemodialysis center to compare the laboratory and clinical differences between responders and non-responders. Inclusion criteria are hemodialysis patients who received the HB vaccine and patients with concomitant hepatitis C. Exclusion criteria are patients who refused the vaccine and patients who did not complete the vaccine course. Results There are a total of 108 subjects included in the study, out of which 44 (42.3%) are responders to the HB vaccine. A multivariate logistic regression was performed using the statistically significant risk factors as identified by the univariate logistic regression, including age range, albumin, hemodialysis vintage, vascular access and diabetes status. The results from the multivariate logistic regression show that advanced age (P = 0.005) and diabetes status (P = 0.003) are found to be strong independent risk factors of responder status. The type of vascular access (AVF or other types) is also marginally statistically significant (P = 0.05). Conclusions In this retrospective chart review comparing HB vaccine in responders versus non-responders, we found that advanced age and a history of diabetes are independent risk factors in predicting responder status.

Abstract
AIM: To investigate the effect of human leukocyte antigen (HLA) DRB1 and DQB1 alleles on the inactive and advanced stages of chronic hepatitis B.
METHODS: Patient records at a single institution’s hepatology clinic were reviewed. Demographic data, laboratory results, endoscopy results, virological parameters, biopsy scores and treatment statuses were recorded. In total, 355 patients were eligible for the study, of whom 226 (63.7%) were male. Overall, 82 (23.1%) were hepatitis B early antigen (HBeAg) positive, 87 (24.5%) had cirrhosis, and 66 (18.6%) had inactive disease. The presence of DQB1 and DRB1 alleles was determined by polymerase chain reaction with sequence-specific primers. The distribution of the genotyped alleles among patients with cirrhosis and patients with chronic active hepatitis was analyzed.
RESULTS: The most frequent HLA DQB1 allele was DQB1*03:01 (48.2%), and the most frequent HLA DRB1 allele was DRB1*13/14 (51.8%). DQB1*05:01 was more frequent in patients with active disease than in inactive patients (27% vs 9.1%; P = 0.002, Pc = 0.026). DRB1*07 was rare in patients with cirrhosis compared with non-cirrhotics (3.4% vs 16%; P = 0.002, Pc = 0.022). Older age (P < 0.001) and male gender (P = 0.008) were the other factors that affected the presence of cirrhosis. In a multivariate logistic regression analysis, DRB1*07 remained a significant negative predictor of cirrhosis (P = 0.015). A bioinformatics analysis revealed that a polymorphic amino acid sequence in DRB1*07 may alter interaction with the T-cell recognition site.
CONCLUSION: This study demonstrates that HLA alleles may influence cirrhosis development and disease activity in Turkish chronic hepatitis B patients.

Abstract
HBV infection remains a major global health problem and continues to be a common cause of liver-related morbidity and mortality in both immunocompetent and immunosuppressed individuals. Reactivation of HBV is a serious complication of chemotherapy/immunosuppressive therapy in patients with HBV infection. In this article, we aim to describe the diagnosis, prevention and management of HBV infection in allogeneic hematopoietic stem cell transplant candidates, from the pre- to post-transplant period. The data currently available suggest that all individuals with hemato-/onco-logical malignancies who undergo chemotherapy/immunosuppressive therapy should be screened for hepatotropic viruses such as HBV and HCV. HBV surface antigen-positive individuals who receive chemotherapy/immunosuppressive therapy are at considerable risk of HBV reactivation. Antiviral prophylaxis prevents HBV reactivation, decreases reactivation-related morbidity and mortality, and prevents interruptions in chemotherapy/immunosuppressive therapy in such individuals. The optimal duration of antiviral prophylaxis remains to be elucidated. The vaccination of HBV-naive recipients and their donors against HBV infection prior to transplantation plays an important role in preventing acquired HBV infection. The presence of hepatitis B surface antigen positivity is not an absolute contraindication for allogeneic hematopoietic stem cell transplantation.

Abstract
Infection is the second most common cause of death in patients with end-stage renal disease (ESRD), following cardiovascular causes. Immunization is a fairly simple, but underutilized, strategy for prevention of infectious morbidity and mortality in patients with kidney failure. It is imperative for nephrologists and primary care providers to have an understanding of immunization as an essential component of preventive healthcare measures in this high-risk population. Patients with ESRD represent a unique population due to their immunosuppressed state, dialysis-related exposures and suboptimal response to routine vaccines. While the Advisory Committee on Immunization Practices (ACIP) provides guidelines for vaccination of patients with renal disease against Hepatitis B, influenza and pneumococcal disease, the data on immunization against other commonly preventable infectious diseases are lacking. This article reviews the recent evidence on immunization in the ESRD population and synthesizes the related implications for maximizing prevention of infectious diseases in this high-risk population.

Abstract
Background Seroconversion following Hepatitis B virus (HBV) vaccine in hemodialysis (HD) patients has been shown to be suboptimal. Nutritional and immunological factors were shown to influence the seroconversion related to HBV vaccination in HD patients. Resistance to erythropoiesis stimulating agents (ESA) for correction of anemia has also been shown to be associated with nutrition and inflammation in these patients. Objectives The aim of the current study was to analyze the relationship between anti-HBs response and erythropoietin (EPO) resistance in HD patients. Patients and Methods Demographics, clinical characteristics, laboratory parameters and the data about vaccination status were obtained from dialysis charts and vaccination registries retrospectively. To calculate the EPO resistance ESA hypo responsiveness index (EHRI) was used. The EHRI was calculated through deviding the weekly dose of EPO by per kilogram of body weight divided by the hemoglobin level. Patients were divided into non-seroconversion (anti-HBs titers were < 10 IU/L) and seroconversion groups (anti-HBs titers were ≥ 10 IU/L) after completion of the four-dose vaccination schedule. Results In total 97 patients were enrolled. For the entire group, stepwise linear regression analysis revealed that square root transformed anti-HBs levels were independently associated with age (P = 0.016), blood urea nitrogen (P = 0.019), high sensitive C-Reactive Protein (P = 0.009), and square root transformed EHRI (P = 0.019). Logistic regression analysis have also demonstrated that blood urea nitrogen (P = 0.002), creatinine (P = 0.046), albumin (P = 0.01) and square root transformed EHRI (P = 0.011) were independently related to seroconversion. Conclusions EPO resistance was negatively associated with anti-HBs levels and seroconversion. More studies are needed to highlight the underlying mechanisms regarding EPO resistance and response to HBV vaccination in HD patients.

Abstract
Some studies showed that in celiac patients the immunological response to vaccination is similar to that one found in general population except for vaccine against hepatitis B virus (HBV). The non-responsiveness to HBV vaccine has also been described in healthy people, nevertheless the number of non-responders has been demonstrated to be higher in celiac disease (CD) patients than in healthy controls. Several hypothesis explaining this higher rate of unresponsiveness to HBV vaccine in CD patients have been described, such as the genetic hypothesis, according with CD patients carrying the disease-specific haplotype HLA-B8, DR3, and DQ2, show a lower response to HBV vaccine both in clinical expressed CD patients and in healthy people carrying the same haplotype. On the other hand, it has been demonstrated that the gluten intake during the vaccination seems to influence the response to the same vaccine. Moreover, it has been demonstrated a possible genetic predisposition to hepatitis B vaccine non-responsiveness likely due to the presence of specific human leukocyte antigen haplotypes and specific single nucleotide polymorphism in genes of cytokine/cytokine receptors and toll like receptors, but the pathogenic mechanism responsible for this low responsiveness still remains unclear. The aim of this review is to focus on the possible pathogenic causes of unresponsiveness to HBV vaccine in CD patients and to propose an alternative vaccination schedule in order to improve the responsiveness to HBV vaccine in this at-risk patients.

Abstract
BACKGROUND Malnutrition is the most common cause of immune deficiency. It results in reduced secretion of T-cells and B-cell-stimulating factors leading to declining of special immunoglobulins. On the other hand, hepatitis B, as a major world health problem, can be prevented effectively by vaccination. Three doses of hepatitis B virus (HBV) vaccine induce protective levels of anti-hepatitis B surface (anti-HBs) in 95% of healthy children. This level decreases gradually over time. OBJECTIVES The goal of this study was to assess anti-HBs in malnourished children, who confronted to some degrees of immune deficiency. PATIENTS AND METHODS This is a cross-sectional study conducted during May to August 2010 in therapeutic clinics of Yazd, Iran. Samples were selected simply and consecutively among 5-6 year-old children with a history of three doses of HBV vaccine in infancy. On the basis of World Health Organization's definition on malnutrition, which considers anthropometric measurements, malnourished children entered the study. Totally 83 cases (37 boys and 46 girls) were gathered and classified into three groups of mild, moderate, and severe malnutrition. One milliliter of venous blood was taken and anti-HBs were tested by enzyme linked immunosorbant assay (ELISA). RESULTS Overall, seroprotection rate and geometric mean titer (GMT) of anti-HBs were 60.2% and 15.47 ± 10.92 mIU/mL, respectively. Seroprotection rate was 71.4%, 55.2%, and 72.7% in mild, moderate, and severe malnourished children, respectively. GMT was 30.78 mIU/mL, 12.15 mIU/mL, and 22.95 mIU/mL in these groups, respectively. None of these two indices were significant in these groups (P = 0.471, P = 0.364). Seroprotection rate and GMT were 54.1% and 13.26 ± 11.59 mIU/mL in boys, and 65.2% and 17.5 ± 10.59 mIU/mL in girls, respectively, showing no significant relationship with gender (P = 0.302, P = 0.602). Lowest seroprotection rate was in stunted cases (47.1%) and highest in wasted children (77.8%). This difference also was not significant (P = 0.43). CONCLUSIONS The seroprotection rate and GMT of anti-HBs observed in this study do not show a high level of immunity. These two indices were not related to severity of malnutrition. We conclude that severity of malnutrition does not affect vaccine-induced antibody level and seroprotection rate; however small sample size in each group of study hinders decisive conclusion. Moreover, GMT and seroprotection rate showed no relationship with type of abnormal anthropometric index, including weight for height, weight for age, and height for age.

Abstract
Background The status of immunocompromised patients is well recognized in end stage renal disease (ESRD). As described recently, this acquired immune dysfunction in the uremic milieu may be one of the main pathogenic factors for mortality in ESRD. The aim of this study was to determine the relationship between the immune response following a hepatitis B vaccination (HBV vaccination) and the survival of maintenance dialysis patients. Methods A total of 156 patients (103 on hemodialysis and 53 on continuous ambulatory peritoneal dialysis) were recruited. After receiving a full dose of the HBV vaccination, all patients were followed up for to 5 years to evaluate the association of patient survival, cause of mortality, and immune response. Results The response rate to the hepatitis B vaccination was 70.5%. There was no significant association between the immune response and the 5-year survival rate (p =0.600) or between the post-vaccination anti-HBs titers and the 5-year survival rate (p = 0.201). The logistic prediction model with the coefficient as non-response following HBV vaccination, diabetes mellitus, old age, and low albumin level could significantly predict infection-cause mortality (sensitivity = 0.842, specificity = 0.937). Conclusion There was no significant association between the immune response to HBV vaccination and the 5-year survival rate. However, non-response following HBV vaccination might be associated with infection-cause mortality in dialysis patients.

Abstract
A high titer of antibody to HBsAg (Hepatitis B virus surface antigen) (anti-HBs) is a requisite for the prevention of HB (Hepatitis B), and adjuvants generally play a great role in eliciting special anti-HBs to HB vaccine. However, adjuvants still need to be improved because of their shortages such as unremarkable efficacy, undesirable side effect or poor security. In this study, we used HBsAg separated from HB patient sera to screen a human liver cDNA expression library, and found a novel HBsAg-binding protein (SBP), which is located at the human chromosome 14q32.33 and is similar to human IgG heavy chain in structure. Western blot demonstrated that SBP existed in both healthy human sera and HB patient sera. Furthermore, SBP could bind to HBsAg by its N-terminal domain. Notably, we confirmed that SBP could promote dendritic cells (DC) to phagocytize HBsAg more effectively and enhance the immunogenicity of HB vaccine, when SBP was mixed proportionally with HBsAg and the resulting mixture was infused into mice. These results suggest that SBP could be developed into a safe and promising adjuvant of HB vaccine.

Abstract
BACKGROUND It is known that the immunogenicity of hepatitis B virus (HBV) vaccine is lower in uremic patients than healthy subjects. Numerous inherited or acquired factors have been implicated in this lowered response, and the high frequency of recombinant human erythropoietin use among patients on maintenance dialysis has been suggested to play a pivotal role. However, the impact of therapy with recombinant erythropoietin on the immune response to HBV vaccine in patients with chronic kidney disease (CKD) is not appropriately detailed. AIM To evaluate the influence of human recombinant erythropoietin therapy on the immunological response to HBV vaccine in CKD patients by performing a systematic review of the literature with a meta-analysis of clinical studies. METHODS We used the random-effects model of DerSimonian and Laird with heterogeneity and sensitivity analyses. The end-point of interest was the rate of patients showing seroprotective anti-hepatitis B titers at completion of a hepatitis B vaccine schedule among human erythropoietin users versus those who did not receive the drug in a CKD population. RESULTS We identified 11 studies involving 862 unique patients with CKD. Aggregation of study results did not show a significant increase in response rates among erythropoietin user versus non-user patients (pooled odds ratio = 1.431; 95% CI 0.954; 2.146), according to a random-effects model. No heterogeneity was found, the p value was 0.1 for our test of study heterogeneity (Q = 14.147). Stratified analysis in various subgroups of interest did not significantly change these findings. CONCLUSIONS Our meta-analysis showed no link between immunological response to HBV vaccine and therapy with human recombinant erythropoietin among individuals on long-term dialysis. We suggest the use of recombinant vaccine towards hepatitis B in patients on regular dialysis irrespective of erythropoietin treatment.

Abstract
BACKGROUND Patients with chronic renal disease should be vaccinated as soon as dialysis is forestalled, and this could improve the seroconversion of hepatitis B vaccination. OBJECTIVES In this study, we aimed to compare seroconversion and immune response rates using 4 doses of 40 μg and 3 doses of 20 μg Euvax B recombinant Hepatitis B surface Antigen (HBs Ag) vaccine administered to predialysis patients with chronic kidney disease (CKD). PATIENTS AND METHODS In an open, randomized clinical trial, we compared seroconversion rates in 51 predialysis patients with mild and moderate chronic renal failure who received either 4 doses of 40 μg or 3 doses of 20 μg of Euvax B recombinant hepatitis B vaccine administered at 0, 1, 2, 6 and 0, 1, 6 months, respectively. RESULTS Differences in seroconversion rates after 4 doses of 40 μg (80.88%) compared to 3 doses of 20 μg (92%) were not significant (P = 0.4124). The mean HBs antibody level after 4 doses of 40 μg at 0, 1, 2, and 6 months (182.2 ± 286.7) was significantly higher than that after 3 doses of 40 μg at 0,1, and 6 months (96.9 ± 192.1) (P = 0.004). Seroconversion after 4 doses of 40 μg (80.8%) was also significantly higher than that after 3 doses of 40 μg (77%) (P = 0.004). Multivariable analysis showed that none of the variables contributed to seroconversion. CONCLUSIONS We found that 4 doses of 40 μg did not lead to significantly more seroconversion than 3 doses of 20 μg.

Abstract
BACKGROUND Patients with chronic kidney disease (CKD) typically show a diminished immune response to hepatitis B virus (HBV) vaccine compared with individuals with intact kidney function. A number of inherited or acquired factors have been implicated in this suboptimal response. Patients with chronic kidney disease frequently have a compromised nutritional status; however, the impact of malnutrition on the immune response to hepatitis B virus vaccine in chronic kidney disease patients remains unclear. AIM To evaluate the influence of nutrition status on the immune response to HBV vaccine in CKD population by performing a systematic review of the literature with a meta-analysis of clinical studies. METHODS Study-specific relative risks were weighted by the inverse of their variance to obtain fixed- and random-effects pooled estimates of impaired vaccine response across the published studies. The risk of poor serological response to HBV vaccine in chronic kidney disease population according to nutritional parameters was regarded as the most reliable outcome end-point. Only studies performing multivariate analysis in order to make adjustments for potential confounders were included. RESULTS We identified seven studies (15,172 unique patients with CKD). The serum protection rate after a full course of recombinant or plasma-derived vaccine towards HBV ranged between 40 and 86%. Aggregation of study results showed an independent and adverse effect of poor nutrition status, as mostly detected by serum albumin levels, on the protection rate after HBV vaccine course; the summary estimate for adjusted RR was 1.50 with a 95% confidence interval (CI) of 1.02, 2.21; R( i ) = 0.01 (random-effects model). The P value for study heterogeneity was significant (Q = 0.0001). In the subgroup of patients who received HBV recombinant vaccine, the relative risk of impaired serological response after HBV vaccination was 1.63 (95% CI, 1.08, 2.45), R( i ) = 0.90, Q = 0.00001, with poor nutritional parameters at baseline. CONCLUSIONS An increased risk exists of impaired serologic response to HBV vaccine response among chronic kidney disease patients having poor nutrition status. Additional studies are needed to understand better the mechanisms underlying the relationship between nutritional status and serological response to HBV vaccine among patients with CKD.

Abstract
BACKGROUND Hepatitis B virus (HBV) vaccination is essential in chronic liver disease (CLD), because it can help prevent acute-on-chronic disease, which has potentially fatal complications. Unfortunately, this group has a significant proportion of HBV vaccination non-responders. A variety of intra-muscular (IM) vaccination methods have been used in an attempt to remedy this poor-response, but with limited success. AIMS Herein is reported the safety and efficacy of high-dose intra-dermal (ID) HBV vaccination in CLD individuals who had failed previous IM standard and boost-dosing regimens. METHODS Forty-eight CLD individuals, known HBcAb negative, who had failed both a three-dose schedule of 40 μg IM vaccination, and boost dosing of either 40 or 80 μg IM, were identified, of which 42 completed the vaccination course. Each received a 40 μg ID total dose (20 μg per arm) during their clinic visits until a response was documented or a maximum of three doses had been administered. HBsAb titer ≥ 10 mIU/ml was regarded as an immunologic response; the intention was to achieve an optimum response of ≥ 100 mIU/ml. RESULTS Twenty-nine of forty-two (69%) individuals had an immunologic response, with 15 (51%) of the responders having the optimum response. No changes in serologic data occurred. No serious dermatologic reactions were observed. No differences between those who responded and those who did not were observed with regard to the presence of cirrhosis, diabetes mellitus, or chronic kidney disease. CONCLUSIONS High-dose ID HBV vaccination of previous CLD non-responders to the standard IM regimen with boost dosing is both safe and efficacious, and should be considered for all such groups.

Abstract
Hepatitis B virus (HBV) infection has been a major global cause of morbidity and mortality. The recognition of the problem led to a worldwide effort to reduce transmission of HBV through routine infant vaccination. HBV infection is the most common cause of chronic liver diseases and hepatocellular carcinoma in Korea. After hepatitis B vaccine era, seroprevalence of hepatits B surface antigen is decreasing, particularly in children. Hepatitis B vaccine is remarkably safe and shows high immunogenicity. Universal childhood immunization with three doses of hepatitis B vaccine in the first year of life is a highly effective method for prevention and control of hepatitis B.

Abstract
BACKGROUND Hepatitis B vaccination is recommended for patients on hemodialysis, however, seroprotection after a primary vaccine series is suboptimum. Limited data are available on the effect of revaccination of non-responders and on persistence of immunity in this population. METHODS Hepatitis B vaccine (40 μg/dose) was given to 77 susceptible patients on hemodialysis (0, 1, and 6 month schedule). Levels of hepatitis B surface antibody (anti-HBs) were tested ≥ 28 days after the third dose was administered, and non-responders revaccinated with an additional 3-dose series. Vaccine responders (anti-HBs ≥10 mIU/mL) were re-tested every 6 months and booster doses given as needed. Kaplan-Meier survival curve was used to estimate the probability of maintaining protective antibody level. Cox-proportional hazards models were used to assess the association between time to loss of protective antibody levels and certain explanatory variables. RESULTS Overall primary vaccine-induced response was 79.2% (95% CI 68.2%, 87.3%), including 49/77 (63.6%; 95% CI 51.8%, 74.7%) patients who received the initial primary hepatitis B vaccine series and 12/21 (57.1%; 95% CI 34.4%, 77.4%) non-responders who were revaccinated with an additional series. Among weak responders (anti-HBs level 10.0-99.9 mIU/mL), protective antibody levels persisted in 44% for 12 months post-vaccination; whereas among strong responders (anti-HBs level ≥100 mIU/mL), protective antibody levels persisted in 92% for 12 months, and 68% for 24 months post-vaccination. A weak post-vaccination response increased the risk of losing protective antibody levels (adjusted hazard ratio, 9.7; 95% confidence interval, 3.5-28.5; p<0.0001). CONCLUSION Revaccinating patients undergoing hemodialysis who do not respond to a primary vaccine series substantially increases the pool of protected patients. The threshold for defining hepatitis B vaccine-induced immunity should be revisited in this patient population to maximize the duration of protection.

Abstract
AIMS To provide a comprehensive and reliable tabulation of available data on the epidemiological characteristics and risk factors for hepatitis B virus (HBV) infection in maintenance hemodialysis (HD) patients in China and help to inform prevention programs and guide future research. METHODS A systematic review was constructed based on the computerized literature database. Confidence intervals (95% CI) of infection rates were calculated using the approximate normal distribution model. Odds ratios (OR) and 95% CI were calculated by fixed or random effects models. Hepatitis B surface antigen positivity (HBsAg (+)) was set as the sign of HBV infection. RESULTS Fifty studies met our inclusion criteria. The pooled prevalence of HBV infection among HD patients in China was 11.9%. Blood transfusion was correlated with an increase in HBV infection (p = 0.05). HD patients with a long-term history were more likely to be infected than those with a short-term history. The levels of alanine aminotransferase were higher in the HBsAg (+) patients (p < 0.001). Large doses of HBV vaccine (80 μg/dose) increased the seroconversion rate. The response rate of intradermal injection of HBV vaccine was higher than that of intramuscular injection. CONCLUSION Hepatitis B is still one of the main complications in HD patients in China, and the frequency of blood transfusion and duration of HD were the risk factors. Large doses and intradermal injection of HBV vaccine were recommended to prevent HBV infection in HD patients. The findings of this meta-analysis have implications for optimal prevention and treatment of Hepatitis B in HD patients.

Abstract
The incidence of hepatitis B virus (HBV) infection in dialysis populations has declined over recent decades, largely because of improvements in infection control and widespread implementation of HBV vaccination. Regardless, outbreaks of infection continue to occur in dialysis units, and prevalence rates remain unacceptably high. For a variety of reasons, dialysis patients are at increased risk of acquiring HBV. They also demonstrate different disease manifestations compared with healthy individuals and are more likely to progress to chronic carriage. This paper will review the epidemiology, modes of transmission and diagnosis of HBV in this population. Prevention and treatment will be discussed, with a specific focus on strategies to improve vaccination response, new therapeutic options and selection of patients for therapy.

Abstract
BACKGROUND The response to recombinant hepatitis B vaccine remains suboptimal among the dialysis population. METHODS In this multi-centre randomized controlled trial, we studied the factors that modify the response to intramuscular Engerix-B vaccination in patients on peritoneal dialysis. The primary aim was to study if a three-dose schedule of extra-high dose (80 microg) of Engerix-B would offer better primary seroconversion and more persistent serological protection than the conventional 40-microg dose. RESULTS Forty-two peritoneal dialysis patients were randomized to receive the conventional 40-microg Engerix-B dose and 45 patients to 80-microg dose. Seroconversion [hepatitis B surface antibody (anti-HBs) level > or =10 IU/l 3 months after completion of the third dose] occurred in 78.6% of patients after 40-microg Engerix-B dosage treatment versus 62.2% for those receiving 80-microg Engerix-B treatment (P = 0.11). After 12 months, the persistence of protective anti-HBs also did not differ between 40- (45.2%) and 80-microg (51.1%) treatment groups (P = 0.67). In contrast, patients with seroconversion 3 months after the third dose of Engerix-B had a higher normalized protein nitrogen appearance (nPNA) than patients without seroconversion (1.16 +/- 0.25 versus 0.96 +/- 0.23 g/kg/day, P = 0.001). Conclusions. We found no evidence of a worthwhile clinical benefit from increasing the three-dose intramuscular Engerix-B vaccine from 40- to 80-microg dose. An unplanned analysis suggested a role of improved protein intake to improve the immune response to hepatitis B vaccine in peritoneal dialysis patients.

Abstract
BACKGROUND Hepatitis B virus (HBV) vaccination is recommended for all individuals with renal failure. Nevertheless, the response rate for this vaccine in hemodialysis (HD) patients is low, ranging from 50% to 80%. The goal of this study was to determine patient characteristics at the initiation of HD that influence HBV vaccine response. METHODS Patients new to HD in an urban population in the United States were retrospectively examined. Analyzed patients were HBV antibody and antigen negative and hepatitis C virus antibody negative at the start of HD, who received HBV recombinant vaccine. Nonresponse was defined as failure to seroconvert (>10 UI/L) after six deltoid intramuscular injections of vaccine. Response was defined as a lasting seroconversion (at least two consecutive positive titers) with </=6 injections. Demographic, laboratory, and kinetic modeling data were examined. RESULTS A total of 33 nonresponders and 64 responders were identified. Univariate analysis demonstrated that nonresponders were older (59 vs. 51 years), had a higher prevalence of diabetes mellitus (DM) (70 vs. 39%), had lower serum albumin levels (3.2 vs. 3.3 g/dL), and had higher dry weights (84 vs. 71 kg) than responders at HD start. In addition, nonresponders had lower normalized protein catabolic rates (0.74 vs. 0.85 g/kg/day) and lower (single-pool) spKt/V(urea)values (0.95 vs. 1.19). Nonresponders had lower serum creatinine levels than responders, despite the greater dry weights. In a multiple logistic analysis model, the presence of DM, age >/= 55 years, body weight >/=80 kg, and normalized protein catabolic rate </=0.75 g/kg/day were associated with HBV vaccination nonresponse. At the end of the vaccination period, nonresponders versus responders continued to have lower serum albumin (3.5 vs. 3.8 g/dL) and creatinine levels (7.8 vs. 10.0 mg/dL) and spKt/V(urea)(1.27 vs. 1.39). CONCLUSION Hepatitis B vaccine nonresponders on HD are older, are more likely to have DM, are more malnourished, and have lower spKt/V(urea) than responders. Nonresponders may also have a different body composition with a lower ratio of lean to total body mass.

Abstract
To confirm and refine associations of human leukocyte antigen (HLA) genotypes with variable antibody (Ab) responses to hepatitis B vaccination, we have analyzed 255 HIV-1 seropositive (HIV(+)) youth and 80 HIV-1 seronegatives (HIV(-)) enrolled into prospective studies. In univariate analyses that focused on HLA-DRB1, -DQA1, and -DQB1 alleles and haplotypes, the DRB1*03 allele group and DRB1*0701 were negatively associated with the responder phenotype (serum Ab concentration > or = 10 mIU/mL) (P = 0.026 and 0.043, respectively). Collectively, DRB1*03 and DRB1*0701 were found in 42 (53.8%) out of 78 non-responders (serum Ab <10 mIU/mL), 65 (40.6%) out of 160 medium responders (serum Ab 10-1,000 mIU/mL), and 27 (27.8%) out of 97 high responders (serum Ab >1,000 mIU/mL) (P < 0.001 for trend). Meanwhile, DRB1*08 was positively associated with the responder phenotype (P = 0.010), mostly due to DRB1*0804 (P = 0.008). These immunogenetic relationships were all independent of non-genetic factors, including HIV-1 infection status and immunodeficiency. Alternative analyses confined to HIV(+) youth or Hispanic youth led to similar findings. In contrast, analyses of more than 80 non-coding, single nucleotide polymorphisms within and beyond the three HLA class II genes revealed no clear associations. Overall, several HLA-DRB1 alleles were major predictors of differential Ab responses to hepatitis B vaccination in youth, suggesting that T-helper cell-dependent pathways mediated through HLA class II antigen presentation are critical to effective immune response to recombinant vaccines.

Abstract
The world's poorest children are likely to be malnourished when receiving their childhood vaccines. It is uncertain whether this affects vaccine efficacy and whether the coadministration of nutrient supplements with vaccines has beneficial or detrimental effects. More recently, a detrimental interaction between vitamin A (VA) supplementation (VAS) and the killed diphtheria-tetanus-pertussis vaccine given in early childhood has been suggested. This report provides a critical review of the published interactions between nutritional status and/or supplementation and vaccine responses in children. Due to an absence of evidence for most nutrients, this analysis focused on protein-energy, vitamins A and D, and iron and zinc. All vaccines were considered. Both observational studies and clinical trials that led to peer-reviewed publications in English or French were included. These criteria led to a pool of 58 studies for protein-energy malnutrition, 43 for VA, 4 for vitamin D, 10 for iron, and 22 for zinc. Our analysis indicates that malnutrition has surprisingly little or no effect on vaccine responses. Evidence for definitive adjunctive effects of micronutrient supplementation at the time of vaccination is also weak. Overall, the paucity, poor quality, and heterogeneity of data make it difficult to draw firm conclusions. The use of simple endpoints that may not correlate strongly with disease protection adds uncertainty. A detailed examination of the immunological mechanisms involved in potential interactions, employing modern methodologies, is therefore required. This would also help us understand the proposed, but still unproven, negative interactions between VAS and vaccine safety, a resolution of which is urgently required.

Abstract
BACKGROUND Disturbances in acquired immunity are considered to be responsible, at least in part, for the high infection rate and inadequate response to vaccinations observed in hemodialysis (HD) patients. The present prospective trial aimed to: (1) evaluate the immunogenicity of a standard influenza vaccine in HD patients, and (2) identify determinants of the immune response. STUDY DESIGN Prospective interventional open-label study. SETTING & PARTICIPANTS 201 long-term HD patients and 41 healthy volunteers. INTERVENTION Vaccination with a standard trivalent inactivated influenza vaccine. OUTCOMES The primary outcome was seroprotection rate, defined as percentage of participants with an antibody titer of 40 or greater 1 month after vaccination. MEASUREMENTS All antibody titers were determined in duplicate by using the hemagglutination inhibition assay. Regression analyses were performed to investigate the association between demographics, uremic retention solutes (including p-cresol), inflammation, nutrition, iron status, trace elements, and immune response in HD patients. RESULTS More than 80% of HD patients showed seroprotection after vaccination. The immune response of HD patients was similar to that of healthy volunteers. Booster vaccination did not improve the immune response. High serum ferritin level was the only parameter independently associated with a better vaccination-induced antibody response in HD patients. LIMITATIONS A high seroprotection rate at baseline undermined the power to identify clinical determinants of the immune response. CONCLUSIONS Influenza vaccination is as efficacious in HD patients as in healthy volunteers. With the exception of serum ferritin, none of the investigated parameters of nutrition, inflammation, and dialysis adequacy had a significant impact on the immune response. Our data support annual vaccination of HD patients and question the clinical relevance of disturbances in acquired immunity in contemporary HD patients.

Abstract
BACKGROUND Hepatitis B vaccine is effective in protection against hepatitis B virus (HBV) infection in haemodialysis (HD) patients, but the antibody response is variable in this population and the persistence of immunity in them remains largely unknown. In this study we aimed to evaluate the efficacy and long-term immunogenicity of hepatitis B vaccine in HD patients. METHODS In this study, we initially offered HBV vaccination as double dose, four vaccine series schedule (40 microg injections intramuscularly in the deltoid muscle at 0, 1, 2 and 6 months) to 54 HD patients who were negative for hepatitis B core antibody and did not receive any dose of HBV vaccine previously. Serum levels of hepatitis B surface antibody (anti-HBs) tested 1-2 months after completion of vaccination. Then we follow the patients up to 1 year after primary vaccination to evaluate the persistence of immunity (as indicated by serum levels of anti-HBs higher than or equal to 10 IU/l). RESULTS After primary vaccination, 87% of patients developed anti-HBs levels above 10 IU/l. 27.8% and 59.2% of them were weak responders and high responders respectively. 13% of patients were non-responders. After 1-year follow-up, 18.18% of responders had lost their anti-HBs (transient responders). All of them were initially in weak responders group and had lower anti-HBs levels. CONCLUSION We found an average percentage of seroconversion after primary HBV vaccination in HD patients. Our study also supported this fact that an antibody titre above 100 IU/l following primary vaccination is necessary to maintain that level of antibody 1 year later.

Abstract
BACKGROUND Anaemia in patients with end-stage renal disease (ESRD) is commonly treated with recombinant human erythropoietin (rHuEPO), often in combination with an adjuvant iron supplement. There is much evidence that rHuEPO can influence the immune response by its effect on lymphocytes. Also, iron catalyses the formation of radicals and increases the risk of major infections by negatively affecting the immune system. The relationship between antibodies to hepatitis B surface antigen (anti-HBsAg) responsiveness after hepatitis B vaccination and rHuEPO/adjuvant iron supplementation has not been reported before. AIM To determine the effects of subcutaneous erythropoietin and intravenous (i.v.) iron therapy on the responsiveness of anti-HBsAg after quadruple hepatitis B vaccination among ESRD patients. METHODS Retrospective medical records were reviewed in a hospital with a tertiary teaching facility. Eighty-three ESRD patients, including 51 who underwent haemodialysis and 32 who underwent peritoneal dialysis therapy, received a quadruple recombinant hepatitis B vaccine. We investigated anti-HBsAg titres in those patients who either received rHuEPO alone (n = 50) or rHuEPO in combination with i.v. iron (n = 33). RESULTS We found that the postvaccination anti-HBsAg titre was significantly lower in the rHuEPO plus i.v. iron group when compared with the group with rHuEPO alone (p < 0.05). The increment of anti-HBsAg between the initial month and the seventh month was positively correlated with therapeutic rHuEPO dosages in the group with rHuEPO alone (r = 0.303, p = 0.033). This relationship was not present in the rHuEPO with i.v. iron group (r = -0.289, p = 0.229). CONCLUSIONS The levels of anti-HBsAg after hepatitis B vaccination are positively correlated with the dose of rHuEPO treatment during the vaccinated period among ESRD patients without i.v. iron supplementation. Also, i.v. iron negatively impacts the responsiveness of anti-HBsAg titre after hepatitis B vaccination in ESRD patients who have undergone rHuEPO therapy.

Abstract
Although the efficacy of hepatitis B vaccines in patients undergoing chronic hemodialysis (HD) treatment has been documented, the persistence of immunity in this population remains largely unknown. In this study we evaluated the persistence of hepatitis B vaccine immunity in HD patients. We followed 37 hepatitis B vaccinated HD patients (following a four-dose vaccination schedule of 40 mug injections intramuscularly in the deltoid muscle at 0, 1, 2, and 6 months) for up to one year to evaluate the persistence of immunity (as indicated by serum levels of hepatitis B surface antibody (anti-HBs) equal to or higher than 10 IU/L). One year after vaccination, 18.9% of patients had lost their anti-HBs (transient responders), while 81.1% still had detectable antibodies in the serum (persistent responders). From 81.1% of persistent responders 11.5% and 88.5% were weak and high responders, respectively. There was no significant difference between persistent and transient responders regarding age, sex, or nutritional factors. We did not find any factors that related to maintaining protective levels of anti-HBs in HD patients. It seems that an antibody titer above 100 IU/L following vaccination is necessary in order to maintain that level of antibody one year later.

Abstract
AIM The aim of this study was to investigate whether haemodialysis (HD) patients suffering from diabetes mellitus could be considered at risk for the development of the protective antibodies to hepatitis B (HB) vaccination and, to evaluate the effectiveness of tetanus toxoid (TT) administrated 2 days before HB vaccination. METHODS Forty-nine HD patients were divided into two groups: group A (19 diabetic patients) and group B (30 non-diabetic patients). A dose of 40 microg recombinant HB vaccine was injected intramuscularly to the patients at 0, 1, 2 and 6 months. RESULTS After the completion of the course, the patients in group A were found to have a lower protective antibody rates than the patients in group B (57.8% vs 70%) (P > 0.05). After the administration of additional booster doses during 12 months, the protective antibody to hepatitis B surface antigen (HBsAb) levels were detected in 78.9% and 96.6% of the patients in group A and group B, respectively (P > 0.05). The patients not having protective HBsAb levels were administered TT and HB vaccines, and after course, all of them have produced protective HBsAb levels. CONCLUSION The present study showed that diabetic patients on HD may carry a greater risk of not seroconverting than non-diabetic ones for antibody response to HB vaccination. The use of TT 2 days before HB vaccination may be a useful and effective method of enhancing the immune response to HB vaccination, especially in the patients with diabetes mellitus on HD.

Abstract
Acquired immunity disturbances in hemodialysis (HD) patients are many and diverse. They are caused by uremia per se, the HD procedure, chronic renal failure complications, and therapeutic interventions for their treatment. Current data suggest that acquired immunity disturbances in HD patients concern mainly the T-lymphocyte and the antigen-presenting cell (APC). The T-lymphocyte-dependent immune response is deficient, predisposing to infections and inadequate response to vaccinations. In addition, APCs are preactivated, which seems to be responsible for the malnutrition-inflammation-atherosclerosis syndrome, and also affects T-lymphocyte function. At the molecular level it is assumed that the interaction between the APC and the T-lymphocyte is impaired. This disturbance is likely to concern the signal that results from the interaction between the major histocompatibility complex:peptide complex on APC surfaces and T-cell receptors on T-lymphocyte surfaces, or the signal that results from the interaction among the co-receptors of these two cells. The aim of the present review was to collect and classify the available clinical and experimental data in this area. Although many pieces are still missing from the puzzle, a better understanding of the responsible molecular mechanisms, will potentially lead to increased survival and a better quality of life in HD patients.
