Methods Twenty-six patients with persistent systemic lupus erythematosus （SLE）, rheumatoid arthritis （RA）, primary Sjogren＇s syndrome （pSS）, or systemic sclerosis （SSc） who had been treated unsuccessfully with conventional treatment were enrolled in the trial in Peking Union Medical College Hospital from September 1999 to June 2004. The patients received HDIT with 200 mg/kg cyclophosphamide followed by an infusion of autologous stem cells that were CD34 selected. Disease acti- vity, adverse effect, hemopoietic and immune reconstitution, and time to recurrence of disease were monitored. Overall treatment related mortality was 7.7% （2/26） with 1 patient died of cytomegalovirus infection and an other of severe pneumonia. Relapse occurred in 3 SLE patients （17.6%） in 37, 26, and 19 months posttransplantation respectively, and 1 RA patient in 15 months posttransplantation. SLE Disease Activity Index （SLEDAI） scores of SLE survivors decreased significantly （P 〈 0.01）. RA patients recorded a drop of Disease Activity Score 28 （DAS 28）. The pSS patient remained symptoms free up to now, more than 50 months aider the transplantation. Conclusion HSCT can be performed relative safely in patients with severe autoimmune disease. Short-term effect of HSCT is promising. However treatment related mortality and relapse were observed in a subset of patients.展开更多

Camels （Camelu sdromedarius） have very small and active antibodies, nanaobodies. Their special properties are being used by the USA Department of Homeland Security as bio-receptors to determine which substance could be used in a biological warfare attack. The antibodies are part of the ＂protective proteins＂ in camel milk. These include potent antibacterial, antiviral and antifungal properties. Camel milk antibodies are, in fact, ＂nanobodies＂. They are not destroyed in their passage through the stomach. These nanobodies are responsible for data concerning the use of camel milk in autoimmune diseases. Various diseases treated with camel milk are presented, as is the mode of action. The effect of pasteurization on activity of camel milk is presented as a way to overcome the need for heat. This is accomplished by presenting ＂pathogen-free＂ camel milk. The antibodies are part of the ＂protective proteins＂ in camel milk. These include potent antibacterial, antiviral and antifungal properties. The effect of pasteurization on activity of camel milk is presented as a way to overcome the need for heat.
