Granulocyte colony-stimulating factor as a novel adjunct to improve hepatitis B vaccination

Abstract

Hepatitis B vaccination is successful in 95% of individuals. In the remainder, despite repeated attempts, immunization often remains unsuccessful. 'Non-response' leaves the individual susceptible to infection. Various strategies have been employed to overcome this. These include the use of adjuncts alongside conventional vaccines which activate immune responses. In this case report we demonstrate the successful use of the hematopoietic growth factor Granulocyte colony-stimulating factor (G-CSF) as a vaccine adjunct in an individual who had previously failed conventional vaccination three times. The patient tolerated the regimen without any side effects and achieved a hepatitis B surface antibody titer greater than 100 IU/L. Use of G-CSF as a vaccine adjunct for hepatitis B has not previously been reported and the outcome in this case suggests that the use of G-CSF in this context warrants further exploration.

INTRODUCTION

WHO recommend universal vaccination with the hepatitis B virus envelope protein (HBsAg) as prophylaxis against hepatitis B virus (HBV) infection. Population based studies in Taiwan conclusively demonstrate that vaccination is an effective intervention to prevent chronic HBV infection and to reduce the risk of liver cancer[1]. Successful vaccination generates antibodies to HBsAg (anti-HBs) at a titer greater than 100 IU/mL which appears to confer durable protection from infection. However, 5%-10% of individuals will fail to develop protective levels of anti-HBs after a conventional course of hepatitis B vaccination[2]. Non-response, defined as a level of anti-HBs less than 10 IU/mL, is more common in people at the extremes of age, smokers, people who are obese and those with chronic conditions such as diabetes mellitus, chronic renal failure, and human immunodeficiency virus (HIV)[3-6]. There also appears to be a genetic basis for non-response and a common observation in non responders is a lower cytokine response to the vaccine[7,8].

Several methods have been postulated to improve vaccine outcome by improving delivery to antigen presenting cells or by inducing the production of immunomodulatory cytokines. These include increasing the dose of the vaccine and the route of vaccine delivery[2]. Several studies have looked at the use of Granulocyte macrophage colony stimulating factor (GM-CSF) as a hepatitis B vaccine adjunct to boost cytokine levels. A meta-analysis of seven studies looking at hepatitis B vaccination in patients with chronic renal failure has shown GM-CSF to statistically improve vaccination rates[9]. In contrast to GM-CSF, Granulocyte colony stimulating factor (G-CSF) is regarded as a lineage specific colony stimulating factor. It mainly affects neutrophils but does also affect antigen presenting cells[10]. This includes a stimulatory effect on Th2 lymphocyte-inducing dendritic cells. A comparative study has suggested that G-CSF is better tolerated than GM-CSF[11]. G-CSF has been used primarily for the treatment of neutropaenia post chemotherapy and in the process of stem cell harvesting. It has not, however, thus far been used as a vaccine adjunct.

CASE REPORT

We describe the case of a 40 year old male with type 1 diabetes since adolescence. He and his partner, a patient with chronic hepatitis B infection, planned to start a family. He had previously received 2 accelerated courses of HBV vaccination with Engerix-B. Following each course no anti-HBs was detectable. A third attempt to generate a vaccine response used an accelerated course of the Twinrix, combined Hepatitis A and B, vaccine. The Twinrix vaccine was chosen as previous reports have identified improved rates of successful vaccination compared with monovalent vaccination[12]. Despite this, an anti-HBs response was not detected. The patient was, however, successfully vaccinated against Hepatitis A.

He was overweight with a body mass index of 29.4 kg/m2. He was noted to have good glycaemic control with HbA1C of 6.4. He did not have any evidence of end organ damage and in particular had an estimated creatinine clearance of 130 mL/min. In addition, he did not have any other co-morbidity and, of note, was HIV negative. A further accelerated course (three doses) of Twinrix vaccine was administered subcutaneously again at 0, 14 and 21 d. Each dose was administered at the same time as 300 μg of subcutaneous G-CSF (Neuopogen). This was the only adjuvant used alongside the accelerated vaccine regimen. He tolerated this vaccination regimen well and had no side effects of note.

Serum analysis was performed 2 mo after his last injection and demonstrated an anti-HBs titre of greater than 100 indicating successful vaccination.

DISCUSSION

This case suggests that G-CSF may be used as a hepatitis B vaccine adjunct in subjects who fail to respond to conventional vaccination regimens. Whilst new vaccines are currently in development promising greater immunogenicity, the increasing use of adjuncts allows for improved vaccination success with the current generation of vaccines. Other vaccine adjuvants that have been used in Hepatitis B vaccination include GM-CSF, type 1 interferons[13], ASO4, ASO2A and CPG 7907[14].

As previously stated, a number of published studies have highlighted the efficacy of GM-CSF as a vaccine adjunct at the dose of 300 μg. At this dose G-CSF is marginally more expensive than G-CSF[15]. However G-CSF may be equally or potentially be more efficacious than GM-CSF. Previous reports have also suggested that G-CSF may be better tolerated than GM-CSF[11].

It is likely that the success of G-CSF as a vaccine adjunct is due to its stimulatory effect on antigen presenting cells[10]. Its effects otherwise are in the main limited to the terminal differentiation of neutrophils with a much lesser multi-lineage effect than GM-CSF.

Further studies are needed to confirm our results and to compare G-CSF with the other commonly used vaccine adjuncts in hepatitis B.
