Needle-related procedures are the most important source of pain and anxiety in pediatric patients. Consequently, needle-phobia and anxiety are common in children with auto-immune disease and immune deficiency and may be barriers to adherence in treatment. The use of a non-pharmacological and easy-to-use approach, like the Buzzy® device, could be an alternative or adjuvant for the management of procedural pain and anxiety of these children during needle-related procedures. This study aims to determine the feasibility, acceptability and satisfaction of the Buzzy® device for procedural pain and anxiety relief of immunology-rheumatology patients undergoing needle-related procedures. The investigators will compare the Buzzy® device with an anaesthetic cream (Maxilene®) during needle-related procedures. The investigators also plan to assess feasibility outcomes and satisfaction of the nurses and the children with the use of the Buzzy® device. This pilot study should refine or modify the research methodology and improve the intervention being piloted before it's efficacy will be verified within a larger scale-study. The investigators strongly believe that the use of the Buzzy® device in immunology rheumatology department could optimise procedural pain and anxiety management. Since most of the treatments administered for auto-immune diseases and immune deficiency diseases are through subcutaneous or intramuscular injections, pain and anxiety management using non-pharmacological and/or pharmacological interventions should be prioritized. Given this knowledge, the investigators feel that this pilot study has the potential to contribute to pain and anxiety management of children undergoing needle-related procedures.
M. A. suffers from hypogammaglobulinemia that has been complicated by refractory Mycoplasma hominis septic arthritis. He has been receiving the antibiotic valnemulin under Emergency Investigational New Drug (eIND) 114686 following many prior treatments with standard antibiotics. M.A. has also been receiving intravenous immunoglobulin (IVIG) replacement. The antibiotic and IVIG have been helpful, but not sufficient for cure. Antibodies have been shown to be critical for defense against mycoplasma. Hyperimmune serum against mycoplasma isolated from rabbit or goat has been effective in cases of chronic erosive arthritis in the setting of immune deficiency, and in some cases resulted in cures. The investigators propose to use M. hominis isolated from M. A. to vaccinate one transgenic cow (developed by SAB Biotherapeutics), purify human antibody after vaccination, test the purified antibody in killing assays to confirm potency, and then administer the purified human IgG to M. A. after FDA compassionate use IND application and local Institutional Review Board (IRB) approval.
Immune Activation persists in HIV-1 infected patients despite efficient antiretroviral treatment. This immune activation is responsible for immune deficiency as well as for non-AIDS related comorbidities, such as non-alcoholic Fatty liver disease, metabolic syndrome or osteoporosis. The goal of this observational transversal multicentric study is to establish the etiologic factors of persistent immune activation in treated HIV-1 infected patients (persistent de novo infection of T CD4+ cells, microbial translocation, active coinfections, immunosenescence, T CD4+ cells lymphopenia, Treg deficiency), its different forms ( activation of T CD4+ cells, T CD8+ cells, B cells, NK cells, monocytes, granulocytes, platelets, endothelial cells or general inflammation) and the potential correlation between causes, forms of immune activation and emergent comorbidities (kidney, bone or liver dysfunction, metabolic syndrome).
