Yes I saw Dr Rudenko at the London Allergy Centre (they specialise in allergy but this is not why I went obviously). It's a bit of a strange place to be honest and at first I was dubious but they did seem to find something that the GP hadn't and I haven't been ill for a year (this is after several years of serious bronchial or flu like illness several times a year).
I would have posted my blood results from the clinic but I can't find them so I've cut and paste extracts from the letter I received. It's hard to follow but basically it says that some specific antibodies against flu like illnesses were below reference ranges so they gave me some injections to try to provoke them into reacting. It seems to have worked.
"Evaluation of a patient's immune response -the ability to fight natural infections is essential in assessment of the humoral compartment of immune system. Presence of common variable immune deficiency (CVID) is the most frequent primary immune deficiency can be screened by assessing the response of immune system to
common infections carbohydrate antigens of pneumococcus, tetanus and haemophilus. In case of inadequate leves of pneumococcal antibodies, response of immune system to carbohydrate antigens is assessed in test vaccination with Prevenar 13. The test vaccine is administered twice with an interval of 4 weeks followed by repeat of levels of serotype specific pneumococcal antibodies.
"Pneumococcal vaccines are an ideal tool to evaluate the ability to produce specific antibodies in response to a known stimulus. All pneumococcal vaccines contain antigens from several serotypes so the immunologic evaluation is not based on a single antibody response. Her Haemophilus influenza antibodies were also below the
reference ranges and I have prescribed test vaccination with Menitorix together with the second dose of Prevenar 13.
"I reviewed results of serotype specific pneumococcal antibodies . Serotype specific antibodies to pneumococcus were detected below the reference ranges. This test will allow us to clarify the likelihood of immune deficiency.
"Epstein-Barr virus screen showed that EBNA IgG antibody level was raised that is immunological evidence of previous infection. Presence of high level of antibodies might be an indirect sign of latency in B cells and possible periodic reactivations might stimulate production of antibodies by plasmatic memory B cells. EBV VCA ab.(IgM) is a marker of active infection (including recent primary) and reinfection was not elevated.
"Immune phenotyping test showed decrease in T limphocytes and all sub populations, ESR at the upper reference range, raised MBL consistent with ongoing infection at the time of the test"
