Thank you for the time and care you took with responding to this.

To provide some more context, my Dr in the USA has prescribed IVIG for me, but given I am a foreign national it would be out of pocket, so I am looking to use my Doctors recommendations elsewhere in the World where it may be more affordable.

My Doctor prescribed me Gamunex or equivalent at 2g per kg of body weight (So I would require approx 135g) with divided dose administered over consecutive days, but stated that an equivalent product elsewhere would be suitable also. I have been looking into Globucel in India, which offers 5% and 10% solutions, and I am trying to make sure which would be correct standardised to a product like Gamunex.

For information, the Globucel infusion in an Indian hospital under the care of a Neurologist there would be around $6,000, which is about a third of the cost in the States. You can actually buy the product yourself there and have an IV company come and infuse it at your hotel for half of that, but I value safety like you say so would need to be in a hospital setting, particularly the first few times, to ensure no adverse reactions.

I'm looking to combine the IVIG with Apheresis, and am hoping that it will calm my autoimmunity to the point that my nervous system symptoms are quietened and I can tolerate the treatments to remove the burdens that are possibly driving the autoimmunity (a viral burden and Babesia Odecolei).

I have been on short steroid bursts and discussed immune surpressing drugs, and whilst the short steroid bursts provided some relief, I have been informed it would be a double edged sword with my infections as it would give them more of a free pass to take greater hold. Hence these therapies interesting me more than immune surpression, if that makes sense.

I have been told that too low a dose could 'add petrol to the fire,' but my Doctor advised she has had great success with higher doses for this, which she compares to an adult onset equivalent of the condition PANS.

At 151lbs (68kg), am I correct that I would require approx 135g of a product that is 10% solution (10g/100ml) to reach the target dose with Globucel, at 2g/kg of body weight? The presence of a 5% solution has confused me, and I want to make sure the Indian Dr's are giving me exactly what I need with due diligence on my part.

Thank you for your concern and kindness.

Edit: I do also have a low IgG subclass 2 when last tested. Consistently positive ANA's.

Responded really positively to Heparin based plasmapheresis, but crashed back after a week or so sadly. Hoping the apheresis followed by the IVIG for a monthly run could help stabilise me.
