How might Rh negative blood be connected to various forms of autoimmune disease?

Kevin, there is a lot of anecdotal evidence of a connection, but I could find almost nothing in the scientific community except for this one article:
The RhD negative subjects expressed many indices of a worse health status. Men, women or both sexes reported more frequent allergic, digestive, heart, hematological, immunity, mental health and neurological problems. They also reported the usage of more drugs prescribed by doctors per day, attended more specialized doctors, namely, dermatologists, gynecologists, internal medicine doctors, neurologists, and psychiatrists (men) in the past two years, a higher frequency of headaches and being tired more often than RhD positive subjects. Incidence of various diseases and disorders also differed between RhD negative and RhD positive subjects, mostly being higher in the former.
RhD negative subjects have increased the risk of developing of certain heart diseases, respiratory diseases and some immunity and autoimmunity related diseases, for example rheumatoid arthritis. The general pattern suggests that RhD negative subjects could have problems with autoimmunity, could be more resistant to infections of viral origin and could be less resistant to infections of bacterial origin.
Threw this in because it is interesting:
People with the Rh negative blood type are more prone to be affected by allergies, especially food allergies. This results in having them being more picky when it comes to food preferences. Studies show that the 15% of humans who lack the rhesus factor are gifted with natural resistance to HIV, small pox and bubonic plague. By being resistant to these diseases, it means that they are less susceptible to suffer from them as opposed to those with the Rhesus factor. Rhesus negative people have a greater oxygen capacity thus are more adaptable to higher altitudes like the mountains. This seems to explain a story about a tribe in China who dies when relocate to lower altitudes. Fascinatingly, they do not require the adjustment most would require when moving to higher altitudes.
