A feedback regulatory pathway between LDL and alpha-1 proteinase inhibitor in chronic inflammation and infection.
Summary
For more than 20 years, alpha-1-proteinase inhibitor therapy has been the standard treatment for patients who have inherited alpha-1-proteinase inhibitor deficiency. Adult patients with this condition eventually develop emphysema. Most HIV-1 patients who have low viral load also have alpha-1-proteinase inhibitor deficiency. The number of CD4 cells in blood increases when alpha-1-proteinase inhibitor increases. Patients will be asked to participate in a pilot study to see whether the use of Zemaira® (alpha-1-proteinase inhibitor) can increase blood levels of alpha-1-proteinase inhibitor and consequently increase CD4 counts.

Eligibility Criteria
Inclusion Criteria
- HIV-1 patients must have confirmed HIV-1 disease, diagnosed using the standard criteria and be on antiretroviral therapy. Patients with inherited alpha-1 proteinase inhibitor deficiency (PIzz) must not have previously received alpha-1 proteinase inhibitor therapy. Uninfected volunteers will be age and gender matched.
- HIV-1 patients must have measurable disease, defined as HIV-1 infected patients on antiretroviral therapy with undetectable HIV RNA (<500 HIV-1 RNA copies/ml) and CD4 counts more than 200 and less than 400 cells/uL.
- Age at least 18 years and under 65 years.
- HIV-1 patients must have active alpha-1 proteinase inhibitor below 11uM (normal is 18-53 uM).
- HIV-1 patients must have one year history (prior to the study) with CD4 counts greater than 200 and less than 400 cells/uL.
- Volunteers must have no evidence of malignancy.
Exclusion Criteria
- Recent illness that will prevent the patient from participating in required study activities.
- Patients receiving other investigational agents.
- Patients with known malignancies.
- Patients with more than 500 HIV RNA copies/mL.
- Patients with more than 400 CD4 cells/uL.
- Uncontrolled illness including, but not limited to, ongoing or active infection, myeloid dysplastic syndrome, anemia, bone marrow failure, DiGeorge Syndrome, thymic disorders, or psychiatric illness/social situations that would limit compliance with study requirements.
