简要总结
To examine the prevalence of humoral immunodeficiency in patients with Chronic Obstructive Pulmonary disease (COPD) by evaluating both immunoglobulin levels and vaccine responses. Patients with COPD and humoral dysfunction will be offered treatment with Subcutaneous Immune Globulin Replacement Therapy (SCIgR) in an attempt to decrease future AECOPD.
详细描述
This will be a non-blinded, randomized study. Patients with COPD will be referred for evaluation by outpatient pulmonary clinics at Rochester Regional health. Following informed consent all patients will be evaluated by checking serum IgG, IgM, and IgA, as well as baseline and post-vaccine IgG to peptides antigens (diphtheria and tetanus) with Td as well as polysaccharide antigens (streptococcus pneumoniae) with pneumococcus polyvalent vaccine-23 (PPV23). Patients with COPD and pre-defined humoral dysfunction (please see below) will be randomized in 1:1 ratio to one of two groups until approximately 20 patients per group are accrued for a total of 40 patients
Group #1: SCIgR with Cuvitru 125 mg/kg/week + standard of care management = 20 patients
Group #2: Standard of care management = 20 patients

结局指标
主要结局
AECOPD requiring treatment with systemic steroids over one year
时间窗: one year
AECOPD is defined by increased respiratory symptoms (e.g., cough, dyspnea, sputum, sputum purulence, wheeze, chest tightness) requiring treatment with systemic steroids.
次要结局
- COPD with pre-defined humoral dysfunction treated with subcutaneous SCIgR will have decreased AECOPD events as compared to COPD with pre-defined humoral dysfunction treated with the standard of care (SOC) management.(one year)
