Hi All,
It seems that there is new publication on POIS ( actually not sure if this been posted here or not ). Here is the link:
http://tau.amegroups.com/article/view/11107/11778
Thanks a lot for the link, jimmy! It has not been posted here yet. And it is interesting!
It is a very good review article by Dr Waldinger, in which he sums up all of his ideas and previous work about POIS. the 5 criterias defining the clinical presentation of POIS, the 7 clusters of symptoms he has defined, the hyposensitization treatment of POIS with autologous semen, discussion on the antigen, and so on.
But what surprises me is that he also add some new ideas, without citing any previous work, and seems to give some hints about his current work !
As an example, the article says "In 2015 Waldinger reported the occurrence of POIS before and after sterilisation in three men. This phenomenon means that the AG is most likely not bound to the spermatozoa but associated with the seminal fluid." and "Indirect clinical evidence suggests that the Ag triggering the POIS systemic reaction is not bound to spermatozoa but to seminal fluid produced by prostatic tissue "" This is not linked to any references, so this may come from a speech he has given or else, it is not specified. Take note that we came to a similar conclusions on the forum, that is, that the antigen is not linked to the semen/spermatozoa but likely to fluids from prostate or seminal glands or Cowper's glands ( see this thread:
http://poiscenter.com/forums/index.php?topic=1555.0 ). Sure, our forum's threads have no value in the scientific world, but now, this mention in Waldinger's review article gives this hypothesis a worldwide scientific credibility.
Elsewhere in the article, it is written that ""To find the Ag in the seminal plasma that causes the auto-immune reaction is of utmost importance for a better understanding of and finding an effective treatment of POIS.", Ag= antigen . I feel this means that current work of Dr Waldinger on POIS is about searching for the possible antigen in prostate fluid. We heard about an ongoing search of Dr Waldinger. I suppose this is the purpose of this current study. I also feel that this review article is a way to summarize what is known up to now about POIS and set the stage for the results that may come next year from his current study.
It is also written in this review article that " The physical and cognitive symptoms of POIS are produced by some specific cytokines that are released by the immunological reaction occurring during ejaculation." and " POIS is not associated with increased total serum IgE concentrations. On the contrary, there are indications that POIS is triggered by specific cytokines that are released by an auto-immune reaction to the man’s seminal fluid.". The part saying that IgE are normal in POIS sufferers has been published in his 2004 paper. But I am not aware that Dr Waldinger has ever written before about specific cytokines being the possible mediators of the hypersensitivity reaction. He does not define further which cytokines he refers to, but by digging reference 2 and reference 3, at the end of the article, you can get some idea of what he has in mind.
From reference 2 in the article ( Vial T, Descotes J. Clinical toxicity of cytokines used as haemopoietic growth factors. Drug Saf 1995;13:371-406. [Crossref] [PubMed] ), you read: " Flu-like and constitutional symptoms, sometimes dose-limiting, have been reported with IL-1, IL-3, IL-4 and IL-6, while M-CSF was occasionally associated with such adverse effects. More specific adverse events, also frequently considered as dose-limiting toxicities, include hypotension with IL-1, severe headache or skin rash with IL-3, and nasal congestion and gastroduodenal lesions with IL-4. Severe capillary leak syndrome has been reported only with IL-4." Many of these effects have been mentioned as POIS symptoms, and considering the complexity of the immune system, it may be considered that the general idea is valid, and may explain many different symptoms not listed here.
I think you may have already noticed that I am very enthusiastic about the auto-immune hypothesis of Dr Waldinger, and that I have myself written a lot about my opinion on the role of pro-inflamatory cytokines as a cause of certain clusters of POIS symptoms, so these affirmations by Dr Waldinger about the role of cytokines in the physiopathology of POIS are just further reinforces my opinion.
Thanks again jimmy!
