Myeloid leukocytes' diverse effects on cardiovascular and systemic inflammation in chronic kidney disease. Basic Res Cardiol 2022; 117:38. [PMID: 35896846 PMCID: PMC9329413 DOI: 10.1007/s00395-022-00945-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Revised: 06/24/2022] [Accepted: 07/11/2022] [Indexed: 01/31/2023]
Abstract
Chronic kidney disease's prevalence rises globally. Whereas dialysis treatment replaces the kidney's filtering function and prolongs life, dreaded consequences in remote organs develop inevitably over time. Even milder reductions in kidney function not requiring replacement therapy associate with bacterial infections, cardiovascular and heart valve disease, which markedly limit prognosis in these patients. The array of complications is diverse and engages a wide gamut of cellular and molecular mechanisms. The innate immune system is profoundly and systemically altered in chronic kidney disease and, as a unifying element, partakes in many of the disease's complications. As such, a derailed immune system fuels cardiovascular disease progression but also elevates the propensity for serious bacterial infections. Recent data further point towards a role in developing calcific aortic valve stenosis. Here, we delineate the current state of knowledge on how chronic kidney disease affects innate immunity in cardiovascular organs and on a systemic level. We review the role of circulating myeloid cells, monocytes and neutrophils, resident macrophages, dendritic cells, ligands, and cellular pathways that are activated or suppressed when renal function is chronically impaired. Finally, we discuss myeloid cells' varying responses to uremia from a systems immunology perspective.

Abstract
According to international guidelines, healthcare workers and medical students immunized against HBV are periodically tested for anti-HBs IgG. Subjects who show an anti-HBs titre <10 mUI/mL must receive additional vaccine doses to induce a measurable antibody response. This study aimed to evaluate the long-time immunogenicity of anti-hepatitis B vaccination in a sample of medical students and residents of the University of Bari who attended the Hygiene Department for biological risk assessment (April 2014-June 2017). The strategy for the management of nonresponder subjects was evaluated. A total of 3676 students and residents were invited for testing according to a standardized protocol. Anti-HBs IgG was tested for in 3140 (85.4%) subjects: 1174/3140 (37.7%) subjects were negative. 14.6% (128/808) of subjects who received the vaccine during their 12th year of life and 45.8% (1056/2305) of subjects immunized during the first year of life (P < 0.0001) were negative. 1005/1174 (85.6%) seronegative subjects received a booster dose, and 903/1005 (89.9%) were tested for anti-HBs 1 month after the booster dose: 82/903 (9.1%) subjects were still negative. Of these, 56/82 (68.3%) received 2 additional doses of vaccine and 52/56 (92.9%) were tested 1 month after the third dose: 50/52 subjects (96.2%) developed a positive titre. In conclusion, several medical students, immunized at birth or at young age against HBV, did not develop protective titres against the virus. Our management strategy (booster retest; for negative subjects, 2 doses and retest) seems consistent with the purpose of evidencing immunological memory.

Abstract
The increasing demand for recombinant vaccine antigens or immunotherapeutic molecules calls into question the universality of current protein expression systems. Vaccine production can require relatively low amounts of expressed materials, but represents an extremely diverse category consisting of different target antigens with marked structural differences. In contrast, monoclonal antibodies, by definition share key molecular characteristics and require a production system capable of very large outputs, which drives the quest for highly efficient and cost-effective systems. In discussing expression systems, the primary assumption is that a universal production platform for vaccines and immunotherapeutics will unlikely exist. This review provides an overview of the evolution of traditional expression systems, including mammalian cells, yeast and E.coli, but also alternative systems such as other bacteria than E. coli, transgenic animals, insect cells, plants and microalgae, Tetrahymena thermophila, Leishmania tarentolae, filamentous fungi, cell free systems, and the incorporation of non-natural amino acids.

Immune Responses to Single-Dose Versus Double-Dose Hepatitis B Vaccines in Healthcare Workers not Responding to the Primary Vaccine Series: A Randomized Clinical Trial. HEPATITIS MONTHLY 2016; 16:e32799. [PMID: 27148385 PMCID: PMC4852093 DOI: 10.5812/hepatmon.32799] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/30/2015] [Revised: 01/25/2016] [Accepted: 01/27/2016] [Indexed: 12/11/2022]
Abstract
BACKGROUND Recommendations to immunize healthcare workers (HCWs) against hepatitis B are well known. However, a proportion of individuals do not respond to the primary standard three-dose HB vaccination schedule. OBJECTIVES The current study aimed to evaluate whether a double-dose HB booster vaccine could induce better protective anti-HB titers than a single-dose booster in non-protected HCWs. MATERIALS AND METHODS This was a randomized clinical trial. A total of 91 HCWs not responding to the primary vaccine series in 2014 were enrolled. The participants were randomized into two groups that received a double dose of the HB vaccine containing 40 µg of antigen or a single dose of the HB vaccine containing 20 µg of antigen in three doses (at zero, one and six months after vaccination). Blood samples were collected before vaccinations and 28 days after the third dose to assess the seroconversion rate, according to the anti-HB antibody titer threshold of > 10 mIU/mL. RESULTS The seroconversion rates were 93.2% and 87.2% after the first booster doses of the double-dose and single-dose HB vaccines, respectively (P = 0.64). In the double-dose HB vaccine group, the seroconversion rate was 97.8% compared with 89.6% in the single-dose group following the second vaccine dose (P = 0.83). All of the participants in both groups were seroprotected after the third HB vaccine dose. CONCLUSIONS Both the single- and double-dose HB vaccines were adequately immunogenic, and the double-dose HB vaccine was not significantly more immunogenic than the single-dose vaccine in terms of the seroconversion rates of HCWs who had not responded to the primary vaccine series.

Abstract
BACKGROUND Dialysis patients are at risk for hepatitis B infection, a serious but preventable disease. Long-term hepatitis B protection has not been defined in pediatric patients with chronic kidney disease stage 5 on dialysis (CKD 5D) who were vaccinated as infants or children. METHODS Annual hepatitis B antibody surveillance data were collected retrospectively on a cohort of pediatric CKD 5D patients (n = 202) at a single institution and analyzed by survival analysis to assess hepatitis B immunity duration. RESULTS Median duration of immunity by Kaplan-Meier analysis since primary vaccination was 106.3 [95 % confidence interval (CI) 93.9, 124.4] months. After the initiation of dialysis, the median duration of hepatitis B immunity was 37.1 (95 % CI 24.2, 72.3) months. Multivariate adjusted analysis showed that there was a significant difference in the duration of hepatitis immunity based on the timing of hepatitis B vaccination (p < 0.001). Patients immunized after starting dialysis had a hazard ratio of 6.13 (95 % CI 2.87, 13.08) for hepatitis B immunity loss compared to patients immunized as infants (p < 0.001). CONCLUSIONS After dialysis initiation, protective hepatitis B antibody levels wane rapidly, with a shortened duration of immunity. In our cohort of pediatric patients with CKD 5D, this decline was more pronounced in children who were immunized after starting dialysis than in those who received hepatitis B immunizations during childhood. Both groups of patients should be monitored with serial antibody titers.

Abstract
BACKGROUND Hepatitis B (HBV) vaccination is an important preventive intervention for HIV-infected population. Data regarding booster HBV vaccine for persons with low HBV surface antibody (sAb) titers after vaccination in this immunocompromised population is lacking. METHODS We randomized 60 HIV-infected subjects lacking HBV protection after completion of 3 doses of HBV vaccine to receive a booster dose of HBV vaccine with 250mcg GM-CSF as an adjuvant or booster vaccine alone. RESULTS GM-CSF was safe with expected side effects. However, only 35% of persons receiving GM-CSF developed protective sAb while 50% in vaccine only arm developed protection (P = 0.47). Overall, only 28% of subjects maintained protective sAb 1 year after vaccination. CONCLUSIONS GM-CSF failed to improve responses to the booster HBV vaccination. Overall, response was poor with only 42% of persons responding at one month post-vaccination confirming booster vaccination with the current HBV vaccine has poor immunogenicity among HIV-infected persons. Further research is needed to develop optimal vaccination strategies in HIV-infected persons.

Abstract
OBJECTIVE To estimate the economic value of dispensing preoperative home-based chlorhexidine bathing cloth kits to orthopedic patients to prevent surgical site infection (SSI). METHODS A stochastic decision-analytic computer simulation model was developed from the hospital's perspective depicting the decision of whether to dispense the kits preoperatively to orthopedic patients. We varied patient age, cloth cost, SSI-attributable excess length of stay, cost per bed-day, patient compliance with the regimen, and cloth antimicrobial efficacy to determine which variables were the most significant drivers of the model's outcomes. RESULTS When all other variables remained at baseline and cloth efficacy was at least 50%, patient compliance only had to be half of baseline (baseline mean, 15.3%; range, 8.23%-20.0%) for chlorhexidine cloths to remain the dominant strategy (ie, less costly and providing better health outcomes). When cloth efficacy fell to 10%, 1.5 times the baseline bathing compliance also afforded dominance of the preoperative bath. CONCLUSIONS The results of our study favor the routine distribution of bathing kits. Even with low patient compliance and cloth efficacy values, distribution of bathing kits is an economically beneficial strategy for the prevention of SSI.

Abstract
BACKGROUND Patients on maintenance dialysis typically show a suboptimal immune response to hepatitis B virus vaccine compared with the non-uraemic population. A variety of inherited or acquired factors have been implicated in this diminished response. It is well known that patients with diabetes mellitus have a compromised immune system, and diabetic nephropathy is an important cause of chronic kidney disease. However, the impact of diabetes mellitus on the immune response to HBV vaccine in patients receiving long-term dialysis remains unclear. AIM To evaluate the influence of diabetes mellitus on the immune response to HBV vaccine in dialysis population 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 antibody against hepatitis B surface antigen at completion of vaccine schedule in the diabetic vs. the nondiabetic dialysis individuals. RESULTS We identified 12 studies involving 1002 unique patients on long-term dialysis. Aggregation of study results showed a significant decrease in response rates among the diabetic vs. the nondiabetic patients [pooled odds ratio=0.52 (95% CI 0.38-0.71)]. The P-value was 0.29 for our test of study heterogeneity. Stratified analysis in various subgroups of interest did not meaningfully change our results. CONCLUSIONS Our meta-analysis showed a clear association between diabetes mellitus and impaired response to hepatitis B virus vaccine in individuals on long-term dialysis. Such a relationship is biologically plausible. Vaccination schedules with adapted vaccine doses and frequent serum testing for loss of immunity against hepatitis B virus should be considered in patients on maintenance dialysis with diabetes mellitus.

Abstract
We evaluated immunologic predictors of response to HBV vaccine administered in the presence or absence of GM-CSF in HIV infected individuals. We measured peripheral blood hematopoietic progenitor, monocyte and myeloid-derived suppressor cell (MDSC) frequencies, and expression of GMCSF receptor on monocytes and MDSCs, at baseline and 4weeks after immunization in relation to antibody response. We observed higher baseline progenitor and lower monocyte frequencies among week 16 antibody responders. Week 4 decline in MDSC frequency was associated with week 16 antibody response, while administration of GM-CSF was associated with preservation of these cells. No significant differences in GM-CSF receptor expression were observed in the presence vs. absence of GM-CSF. These findings are consistent with a positive role of progenitor cells and a potential negative role of monocytes in vaccine response. Additionally, GM-CSF augmented the preservation of peripheral blood MDSC, which may contribute to the lack of improved vaccine responses.

Abstract
BACKGROUND Currently more than 340,000 individuals are receiving long-term hemodialysis (HD) therapy for end-stage renal disease and therefore are particularly vulnerable to influenza, prone to more severe influenza outcomes, and less likely to achieve seroprotection from standard influenza vaccines. Influenza vaccine adjuvants, chemical or biologic compounds added to a vaccine to boost the elicited immunologic response, may help overcome this problem. STUDY DESIGN Economic stochastic decision analytic simulation model. SETTING & PARTICIPANTS US adult HD population. MODEL, PERSPECTIVE, & TIMEFRAME The model simulated the decision to use either an adjuvanted or nonadjuvanted vaccine, assumed the societal perspective, and represented a single influenza season, or 1 year. INTERVENTION Adjuvanted influenza vaccine at different adjuvant costs and efficacies. Sensitivity analyses explored the impact of varying influenza clinical attack rate, influenza hospitalization rate, and influenza-related mortality. OUTCOMES Incremental cost-effectiveness ratio of adjuvanted influenza vaccine (vs nonadjuvanted) with effectiveness measured in quality-adjusted life-years. RESULTS Adjuvanted influenza vaccine would be cost-effective (incremental cost-effectiveness ratio <$50,000/quality-adjusted life-year) at a $1 adjuvant cost (on top of the standard vaccine cost) when adjuvant efficacy (in overcoming the difference between influenza vaccine response in HD patients and healthy adults) ≥60% and economically dominant (provides both cost savings and health benefits) when the $1 adjuvant's efficacy is 100%. A $2 adjuvant would be cost-effective if adjuvant efficacy was 100%. LIMITATIONS All models are simplifications of real life and cannot capture all possible factors and outcomes. CONCLUSIONS Adjuvanted influenza vaccine with adjuvant cost ≤$2 could be a cost-effective strategy in a standard influenza season depending on the potency of the adjuvant.

Abstract
HIV-infected persons are at risk for HBV co-infection which is associated with increased morbidity and mortality. Unfortunately, protective immunity following HBV vaccination in HIV-infected persons is poor. This randomized, phase II, open-label study aimed to evaluate efficacy and safety of 40 mcg HBV vaccine with or without 250 mcg GM-CSF administered at day 0, weeks 4 and 12. HIV-infected individuals >or=18 years of age, CD4 count >or=200 cells/mm(3), seronegative for HBV and HCV, and naïve to HBV vaccination were eligible. Primary endpoints were quantitative HBsAb titers and adverse events. The study enrolled 48 subjects. Median age and baseline CD4 were 41 years and 446 cells/mm(3), 37 were on ART, and 26 subjects had undetectable VL. Vaccination was well tolerated. Seven subjects in the GM-CSF arm reported transient grade >or=2 signs/symptoms (six grade 2, one grade 3), mostly aches and nausea. GM-CSF had no significant effect on VL or CD4. Four weeks after vaccination, 26 subjects (59%) developed a protective antibody response (HBsAb >or=10 mIU/mL; 52% in the GM-CSF arm and 65% in the control arm) without improved Ab titer in the GM-CSF vs. control arm (median 11 mIU/mL vs. 92 mIU/mL, respectively). Response was more frequent in those with CD4 >or=350 cells/mm(3) (64%) than with CD4 <350 cells/mm(3) (50%), though not statistically significant. GM-CSF as an adjuvant did not improve the Ab titer or the development of protective immunity to HBV vaccination in those receiving an accelerated vaccine schedule. Given the common routes of transmission for HIV and HBV, additional HBV vaccine research is warranted.

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
Immunization is the most effective way to prevent transmission of HBV and, hence, the development of acute or chronic hepatitis B. The national strategy to eliminate transmission of the virus in the United States includes vaccination of all newborn infants, children, adolescents, and high-risk adults. Postexposure prophylaxis is also advocated, depending on the vaccination and anti-HBs status of the exposed person. Seroprotection after vaccination, defined as anti-HBs > or = 10 mIU/mL, is achieved in over 95% of all vaccinees. The hepatitis B vaccines are very well tolerated with usually minimal adverse effects. Predictors of non-response include increasing age, male gender, obesity, tobacco smoking, and immunocompromising chronic dis-ease. For those who remain nonresponders after the second series of vaccination, adjuvants such as GM-CSF may be considered, but their results are variable.

Abstract
BACKGROUND T-cell anergy, as measured by delayed hypersensitivity skin testing, is associated with increased susceptibility to infection. Because the repertoire of effects of granulocyte-macrophage colony-stimulating factor (GM-CSF) includes enhancement of antigen processing and presentation by antigen-presenting cells, GM-CSF has been used to augment immune function in human immunodeficiency virus-induced and other viral illness-induced immune dysfunction and to affect positively immune function in a wide variety of disorders. OBJECTIVE To attempt reversal of T-cell anergy using GM-CSF in 3 otherwise immunologically healthy children with severe recurrent and persistent viral respiratory tract infections and in one child with recurrent bacterial sepsis. METHODS After written informed consent and baseline data were obtained, the study participants were administered 3 two-week cycles of GM-CSF. Delayed hypersensitivity skin testing and laboratory tests were repeated 2 weeks after the third cycle and subsequently as clinically indicated. RESULTS All 4 children developed delayed hypersensitivity by skin testing, and all demonstrated markedly decreased number and severity of infection. Improvement persisted in all patients for at least 1 year. A single cycle of additional treatment in 2 patients reestablished delayed hypersensitivity and decreased infection, both of which persisted throughout the follow-up period of 4 or more years. CONCLUSIONS GM-CSF treatment reversed T-cell anergy in 4 children. Reestablishment of delayed hypersensitivity was associated with a significant decrease in infection. Although further studies will be needed, use of GM-CSF should be considered as an immune modulator in patients with T-cell anergy and recurrent infections.

Abstract
BACKGROUND Patients undergoing dialysis usually have a poor response to conventional hepatitis B vaccination. AIM To observe the effects of intradermal hepatitis B (HB) vaccination in a 13-month prospective study of adult patients with end-stage renal failure. The patients were with or without previous hepatitis B vaccination, but all had antibody titres <10 mUI/mL. METHODS Patients were allotted to two groups: previous hepatitis B virus vaccination and no previous hepatitis B virus vaccination or anti-HBs titres <10 mUI/mL. Patients in both groups received 16 i.d. injections of 0.1 mL of hepatitis B virus vaccine over an eight-week period. Patients had antibody titres assessed before vaccination, 1 month after and every 3 months for a year. Antibody titres >/=10 mUI/mL were considered protective. RESULTS Seventy patients completed the protocol. Protective titres were elicited in 82% of each group. Age, time under dialysis, diabetes, smoking and body-mass index were not associated with seroconversion. Persistent protective titres >12 months occurred in 27 (58.7%). Adverse events were trivial. CONCLUSION Intradermal hepatitis B virus vaccination is an alternative in end-stage renal failure.

Abstract
The efficacy of granulocyte macrophage colony-stimulating factor (GM-CSF) to enhance the immune response to hepatitis B virus vaccine has been object of several reports. We searched for randomized controlled clinical trials comparing GM-CSF given concomitantly to hepatitis B virus vaccine to vaccine given alone or with placebo. Data on rates of seroconversion (anti-HBs titers >10 IU/ml) from 13 studies (734 subjects) produced combined estimates that favored GM-CSF as compared to controls: rate ratio after a single immunization was 1.54 [95% confidence interval (CI), 1.04-2.27] and 1.20 (95% CI, 1.02-1.42) at the end of the vaccination cycle. Using a logistic approach a significant dose/response effect of GM-CSF was seen. Moreover, in renal failure patients who have responded to the vaccine, GM-CSF increased anti-HBs titers. Our findings suggest that GM-CSF induced a significant effect in terms of response rate and achievement of an earlier seroconversion to the vaccine in the overall populations examined, in renal failure patients and in healthy individuals.

Abstract
BACKGROUND Chronic dialysis patients often fail to produce protective antibodies to hepatitis B virus surface antigen after vaccination towards hepatitis B virus (HBV). Several authors suggested a benefit for granulocyte macrophage-colony stimulating factor (GM-CSF) as an adjuvant to HBV vaccination in patients with end-stage renal disease (ESRD). However, consistent information is still lacking. AIMS To evaluate efficacy and safety of GM-CSF as adjuvant to hepatitis B vaccine in patients with ESRD by performing a systematic review with a meta-analysis of prospective controlled clinical trials (CCTs). METHODS Only trials comparing the seroresponse rate in study (GM-CSF plus HBV vaccine) versus control (HBV vaccine alone) patients were included. 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 HBV vaccine schedule in study versus control groups. RESULTS We identified seven studies involving 187 unique patients with ESRD. Only prospective CCTs were included. Pooling of study results showed a significant increase in response rates among study (GM-CSF plus HBV vaccine) versus control (HBV vaccine alone) patients (pooled Odds Ratio, 4.63 [95% Confidence Intervals, 1.42; 15.14]). The P-value was 0.02 for our test of study heterogeneity. CONCLUSIONS Our meta-analysis showed improved seroprotection rates with HBV vaccine after GM-CSF administration.

Abstract
Methyl inosine 5'-monophosphate (MIMP) was designed and synthesized in an endeavor to generate compounds with immunostimulatory activity based on the precedent of purines, particularly inosine playing a central role in the development and function of the immune system. This review will summarize the immune-enhancing effects of MIMP on a variety of immunological responses both in vitro and in vivo. Among these studies, MIMP displays protective effects in several in vivo models of infectious disease following administration by one of several routes including oral. Furthermore, MIMP enhanced responses to Hepatitis B and influenza vaccines. Vaccination represents an extremely powerful tool for combating a variety of diseases, perhaps even cancer. However, to date, vaccines have been limited by their inability to produce cell-mediated responses and by the low immunogenicity of soluble/subunit antigens. In addition, there are difficulties in eliciting sufficient responses in immunocompromised individuals, which includes the elderly, due to the natural immunosenescence that occurs with aging. The data described here suggest that MIMP could be used to overcome some of these limitations. The application of MIMP as an adjuvant to the influenza vaccine, focusing on the elderly, at-risk populations will be discussed in more detail; however, several other bacterial and viral vaccine and/or disease targets merit further consideration.

Abstract
PURPOSE To determine whether granulocyte-macrophage colony-stimulating factor (GM-CSF) would improve response to influenza vaccination in cancer patients. PATIENTS AND METHODS In a randomized, patient-blinded, placebo-controlled trial carried out in 1997 to 2000, 133 patients were stratified into five groups of treatment and disease. Single doses of standard split trivalent influenza vaccine and either placebo or 250 micro g of GM-CSF were administered at the same time. Hemagglutination inhibition assay titers were measured before and 4 weeks after vaccination. RESULTS Standard analyses, which define response as at least a four-fold increase in titers, detect no effect of GM-CSF for any of the three influenza subtypes in the trivalent vaccines (P >or=.12). Analysis that includes the magnitude of the change in titers and combines responses of the subtypes suggests that the placebo group had the greater response (P =.051), thus indicating that GM-CSF does not improve response. Ancillary analyses show that response declines both with increasing age and with higher initial titers. The fraction of patients with at least a four-fold increase in titers was 0.36 (95% confidence interval, 0.29 to 0.42) CONCLUSION A single 250- micro g dose of GM-CSF administered with the influenza vaccine does not improve response to vaccination. Response in cancer patients is low and declines as age and initial titer increase.
