M Joseph John, Amrith Mathew, Sunil Bhat, Anushree Prabhakaran, Biju George, Jacob John
BACKGROUND: Hematopoietic stem cell transplant (HSCT) recipients are more susceptible to infections from vaccine preventable diseases (VPDs) than the general population. Indian stem cell transplant registry (ISCTR) post-BMT vaccination guidelines were formulated in 2015. The objective of the survey was to assess the compliance to these guidelines among transplant physicians in India. MATERIALS AND METHODS: This is a cross-sectional survey executed as the quantitative research strategy to explore the various aspects of vaccination practices among transplant physicians in India...

The human cytomegalovirus (HCMV) virion envelope protein glycoprotein B (gB) is essential for viral entry and represents a major target for humoral responses following infection. Previously, a phase-2 placebo-controlled clinical trial conducted in solid organ transplant candidates demonstrated that vaccination with gB plus MF59 adjuvant significantly increased gB ELISA antibody levels whose titer correlated directly with protection against post-transplant viremia. The aim of the current study was to investigate in more detail this protective humoral response in vaccinated seropositive transplant recipients...

BACKGROUND: Solid organ transplant recipients are at increased risk for reactivation of herpes zoster, or shingles, and have a higher frequency of serious complications including post-herpetic neuralgia. A live, attenuated shingles vaccine is effective and approved for individuals 50 years and older. The vaccine is contraindicated following transplantation but may be used in patients with renal failure. Utilization of the vaccine has been poor in patients with end-stage renal disease, including those awaiting transplant, due to concerns for safety, efficacy, and potential sensitization prior to transplant...

BACKGROUND: Conjugated pneumococcal vaccine is recommended for kidney transplant recipients however their immunogenicity and potential to trigger allograft rejection though generation of de-novo anti-human leucocyte antigen antibodies has not been well studied. METHODS: Clinically stable kidney transplant recipients participated in a prospective cohort study and received a single dose of 13-valent conjugate pneumococcal vaccine. Anti-pneumococcal IgG was measured for the 13 vaccine serotypes pre and post vaccination and functional anti-pneumococcal IgG for 4 serotypes post-vaccination...

BACKGROUND: This is an update of the Cochrane review published in 2013, Issue 10.Immunosuppressed cancer patients are at increased risk of serious influenza-related complications. Guidelines, therefore, recommend influenza vaccination for these patients. However, data on vaccine effectiveness in this population are lacking, and the value of vaccination in this population remains unclear. OBJECTIVES: To assess the effectiveness of influenza vaccine in immunosuppressed adults with malignancies...

Standardised approaches to functional immune assessment after haematopoietic cell transplantation (HCT) are lacking. A 12-year-old girl with relapsed acute myelogenous leukaemia, 2 years post-unrelated HCT, underwent immunological evaluation prior to receiving live vaccinations. Assessment of standard immune parameters and T-cell proliferation to phytohaemagglutinin was reassuring. She was given Varicella vaccination based on usual post-transplant protocols but was hospitalised 10 days later with localised Varicella infection (vaccine strain)...

Background: Most RSV vaccine candidates include fusion (F) protein in different conformations. Antigenic site II found in the different F conformations is the target of palivizumab, the only FDA approved monoclonal antibody (mAb). Serum palivizumab-like antibody (PLA) is a potential serologic correlate of immunity. The objective was to determine if different conformations of F protein in a palivizumab competitive antibody (PCA) assay affect the PLA concentrations. Methods: Four PCA assays were standardized using mAbs...

BACKGROUND: Avoidance of vaccine-preventable infections in paediatric renal allograft recipients is of utmost importance. However, the development and maintenance of protective vaccination titres may be impaired in this patient population owing to their need for immunosuppressive medication. METHODS: In the framework of the Cooperative European Paediatric Renal Transplant Initiative (CERTAIN), we therefore performed a multi-centre, multi-national study and analysed vaccination titres pre- and post-transplant in 155 patients with serial titre measurements in comparison with published data in healthy children...

Guidelines recommend vaccination starting 12 months after autologous hematopoietic stem cell transplant (aHCT), but there is varying practice for patients on maintenance therapy, with some centers not immunizing at all. Because of decreased vaccine rates among the general population causing loss of herd immunity, we aimed to establish the safety and efficacy of revaccinating multiple myeloma patients on lenalidomide maintenance (LM). Of the 122 patients who were vaccinated after aHCT between 2010 and 2014 at Memorial Sloan Kettering Cancer Center, 91 (75%) were on LM...

There are no approved vaccines or virus-specific treatments for human parainfluenza viruses (PIVs), which have recently been reclassified into species human respirovirus 1 and 3 and human rubulavirus 2 and 4 These viruses cause morbidity and mortality in immunocompromised patients including those undergoing hematopoietic cell transplant (HCT). No small-animal models exist for non-invasive imaging of respiratory viral infection in the HCT host despite the utility such a system would offer to monitor prolonged infection, its clearance, and treatment options...

Fanconi anemia (FA) is a rare genetic disorder associated with predisposition to head and neck and gynecological squamous cell cancers. In the general population, these cancers are commonly linked to human papillomavirus (HPV) infection. Antibodies to natural HPV infection and HPV vaccination were evaluated in 63 individuals with FA while considering host immune factors. Approximately 30% of reportedly unvaccinated participants were seropositive (HPV6-38%, HPV11-25%, HPV16-26%, and HPV18-26%). Seropositivity was significantly associated with having had sex regardless of age (p=...

BACKGROUND: Because infections constitute a major cause of morbidity and mortality in paediatric renal allograft recipients, avoidance of preventable systemic infections by vaccination before transplantation is of utmost importance. However, data on the completeness of vaccinations and factors associated with incomplete vaccination coverage are scarce. METHODS: Within the framework of the Cooperative European Paediatric Renal Transplant Initiative (CERTAIN), we therefore performed a multi-centre, multi-national, retrospective study investigating the vaccination coverage before transplantation of 254 European children with end-stage renal disease (mean age 10...

Few studies have evaluated the response of allogeneic hematopoietic stem cell transplantation [allo-HSCT] recipients to pneumococcal polysaccharide vaccine-23 [PPSV23] in the modern transplant era when more elderly patients undergo allo-HSCT. We administered a single dose of PPSV23 to 30 allo-HSCT recipients and evaluated serotype-specific antibody responses using IgG measured by enzyme-linked immunosorbent assay and opsonophagocytic assay [OPA] titers in a multiplexed opsonophagocytic killing assay. The median patient age was 54 years [range, 23-68], and the interval from allo-HSCT to vaccination was 756 days [range, 389-1903]...

Organ and stem cell transplantation has been one of the greatest advances in modern medicine, and is the primary treatment modality for many end-stage diseases. As our population ages, so do the transplant recipients, and with that comes many new challenges. Respiratory viruses have been a large contributor to the mortality and morbidity of solid organ transplant (SOT) and hematopoietic stem cell transplant (HSCT) recipients. Respiratory viruses are generally a long-term complication of transplantation and primarily acquired in the community...

The four dengue virus serotypes (DENV1 to 4) cause dengue, a major public health problem worldwide. Individuals exposed to primary DENV infections develop serotype-specific neutralizing antibodies, including strongly neutralizing antibodies targeting quaternary epitopes. To date, no studies have measured the levels and kinetics of serum antibodies directed to such epitopes among populations in regions where dengue is endemic. Here, we use a recombinant DENV4 (rDENV4/3-M14) displaying a major DENV3 type-specific quaternary epitope recognized by human monoclonal antibody 5J7 to measure the proportion, magnitude, and kinetics of DENV3 type-specific neutralizing antibody responses targeting this epitope...
