My Summary Assessment of Immunoglobulin IVIG for CIDP 2016 until now: Intravenous Infusions (IVIG) or Sub-cutaneous (Sub-Q)

As at March 2, 2016. I have had four IVIG campaigns since March 2011 but I only started keeping full log of its effect from July 2013. I treated the March 2011 IVIG campaign as a standard therapy that was going to cure me of CIDP and was somewhat taken back when two years later I required more treatment with a campaign starting July 2013. I have kept some monthly and more recently daily records of how I feel on each of the symptoms caused by my CIDP since that campaign. I have tried to be as scientific as one can be trying to measure real happenings that day - such as whether my leg actually fully cramped. It is qualitative but I have found that my indices follow reasonably closely with parallel medical conductive studies I have had periodically. IVIG has not cured me of CIDP, but I feel much better on IVIG than when I am off it. Indeed I hate to think where I would be now with my CIDP if I had not had access to this blood product! I have received various brands of IVIG (Gamunex, Privigen, IGIVnex) as well as SCIG (Hizentra) and have recorded the dates. Using my analysis I have found Gamunex to be significantly best for me both in terms of effectiveness in reducing CIDP symptoms and with the least side effects (I will post the this IG brand analysis on another page once it is complete). Details of each campaign are given on other pages but the following is my summary assessment of the IVIG impacts I have experienced -

 

Summary IVIG Effectiveness 2013-2016
» IVIG was quite effective early on (2013) in my CIDP history but less so lately (2015-2016) but overall extremely helpful in my CIDP management and daily life!
» Indeed the 2013-14 campaign was so effective that my recovery continued afterwards for seven months
» My (life threatening) breathing issue was averted in 2013 and IVIG is still undeniably in 2016 protecting me
» In the 2015 campaign, early encouraging signs were reversed, I theorize due to overdosing with three loading doses (Conductive studies found I had actually worsened during the campaign)
» It seems from the detailed analysis that the older the symptom the more effective IVIG is in controlling it: For me very notable mitigation of "electrical vibrations", fasciculations, cramping, sea-sickness and breathing
» Indeed, the last campaign (2015) was completely ineffective against new upper body symptoms

» Symptom relief from my CIPD can take a day after first infusion (eg., fasciculations, vibration, cramping, pain reduction) to several months (eg., balance, motion, and breathing issues)
» Subcutaneously infused IG - Sub-Q or SCIG late 2015 - of Hizentra proved ineffective in my case although I would like a re-trial as I believe extraneous circumstances (loading doses) intervened in my one trial

»The maintenance low-dose IVIG commenced march 2016 are adequate but the overall impact of low maintenance dose on my symptoms are less effective than the usual full dose - as of my 9th dose mid-October 2016 I am beginning to question its efficacy as my symptoms are barely tolerable and new upper body issues getting worse
» October 26, 2016 blood tests show I have elevated thyroid TSH and Pituitary FSH hormones**. Investigations continue Nov 14, 2016 and I hope this is not serious - I will find out more January 5, 2017

» December 6, 2016 the CIDP clinic says conductive studies indicate stability (since March 2016). This should be good news but for me represents a significant disconnect with the symptoms I live with every day. My IVIG maintenance therapy is to continue - I certainly hope I am wrong on the progression issue!.

» April 2, 2017 a year into the maintenance dose of 40 g IVIG every four weeks I feel my symptoms are stabilizing albeit at an uncomfortable level for daily living. However, the stability is comforting and confirmed July 19, 2017 by EMG!

The above is my summary log chart and findings on my CIDP infusions but

the detailed impact of each IVIG campaign can be viewed at the following links -

 

  • Daily log of response to 2nd eight-months round of IVIg July 2013 - April 2014
  • Monthly log of IVIG impacts March-October 2015
  • Log of Sub-Q trial SCIG (subcutaneous self-infused Hizentra) Oct 2015.
  • Low "Maintenance Dose" Trial IVIG Treatment for CIDP 2016
  •  

    * My usual IVIG dose is 72 g infused once per month or 1g per kg body weight per month.

    ** TSH = Thyroid Stimulating Hormone FSH = Follicle Stimulating Hormone I will see a endocrinologist November 14, 2016 to investigate why these two hormones are elevated. I am concerned that IVIG has caused this or alternatively that I have some kind of Autoimmune Polyendocrine Syndrome.
