== Scientific papers discussing IVIG treatment of conditions commonly found in long haulers ==

* ''How We Treat '''Autoimmune Small Fiber Polyneuropathy''' with Immunoglobulin Therapy'' - https://doi.org/10.1159/000498858
<blockquote> Our experience with the use of IVIg in patients with autoimmune autonomic neuropathy matches that which has been reported by Oaklander and Flanagan with a response rate of approximately 75–80%. Many patients improve by 80–90% of their pre-illness level of functioning.</blockquote>
* ''IVIG for apparently '''autoimmune small-fiber polyneuropathy''': first analysis of efficacy and safety'' - https://pubmed.ncbi.nlm.nih.gov/29403541/
<blockquote> Overall, 74% of patients rated themselves 'improved' and their neurologists labeled 77% as 'IVIg responders'; 16% entered remissions that were sustained after IVIg withdrawal. All adverse events were expected; most were typical infusion reactions. The two moderate complications (3.6%) were vein thromboses not requiring discontinuation. The one severe event (1.8%), hemolytic anemia, remitted after IVIg discontinuation.</blockquote>
* ''Evidence of '''small-fiber polyneuropathy''' in unexplained, juvenile-onset, widespread pain syndromes'' - https://pubmed.ncbi.nlm.nih.gov/23478869/
<blockquote> Treatment with corticosteroids and/or intravenous immune globulin objectively and subjectively benefited 80% of patients (12/15).</blockquote>
Note: the article above describes treatment with corticosteroids.  Some long haulers see a very noticeable increase in symptoms with corticosteroids so a conservative approach towards corticosteroids may be prudent.

* ''Successful treatment of '''postural orthostatic tachycardia''' and '''mast cell activation syndromes''' using naltrexone, immunoglobulin and antibiotic treatment'' - https://pubmed.ncbi.nlm.nih.gov/29326369/
<blockquote> A patient with severe postural orthostatic tachycardia syndrome (POTS) and mast cell activation syndrome (MCAS) received immunotherapy with low-dose naltrexone (LDN) and intravenous immunoglobulin (IVIg) and antibiotic therapy for small intestinal bacterial overgrowth (SIBO). A dramatic and sustained response was documented. </blockquote>

== Support group ==

The [https://www.facebook.com/groups/653413942477238 ''IVIG for V & C19'' support group] is a place where patients share information about sympathetic doctors, information on testing for autoimmune SFN / small fiber polyneuropathy, etc. etc.
