Active clinical trials for "Immunologic Deficiency Syndromes"

The purpose of this study is to demonstrate the utility of measuring outcomes in 5% treatment naïve Intravenous Immunoglobulin (IVIg) Primary Immunodeficiency Disease (PIDD) patients using infusion nurse and patient measured physical, quality of life (QOL), respiratory, and disability assessments using CareExchange in the home setting.

This study of Kaletra (Lopinavir (LPV)/Ritonavir (RTV)) tablets will be conducted to clarify the following with regard to treatment with this drug: Incidence and conditions of occurrence of adverse reactions in the clinical setting Factors that may affect the safety and effectiveness of Kaletra (QD)

The purpose of this study is to compare the results for HIV and/or Hepatitis C Virus antibody testing when using routine plasma versus SMARTplasma from the same blood sample. SMARTplasma is enriched for antibodies via a stimulation step of whole blood in a SMARTube™ (SMARTstim™ in the USA).

To determine the incidence of tuberculosis in an inner city population, identify risk factors for TB, describe the natural history in adults and children, evaluate the effect of Mycobacterium tuberculosis (Mtb) co-infection on the progression of human immunodeficiency virus disease, and determine factors that contribute to compliance and non-compliance with prophylaxis and treatment.

To determine the prevalence and natural history of pulmonary and cardiac complications associated with HIV infection in utero, in infancy, and during early childhood.

To evaluate factors influencing the risk of transfusion-transmitted human immunodeficiency virus (HIV) infection and its progression to clinically significant manifestations.

Children and adolescents with HIV/AIDS are living well beyond life expectancy that was projected for them in the recent past. Little is known about the psychosocial variables that coincide with long-term survival of HIV/AIDS. This longitudinal study examines the psychosocial factors and adaptive coping strategies associated with long-term survival of HIV/AIDS in children and how these factors change over a period of two years. In addition, data is being collected from the primary caretakers on their own psychological well-being as will as their perceptions of their child's adjustment and coping. Participants include children who have been infected (either perinatally or through transfusion) for at least eight years and who were aware of their diagnosis.

This study will examine how quickly white blood cells called CD4 lymphocytes reproduce and how long they live in people infected with HIV. It will do this using bromodeoxyuridine (BrDU), a compound that is structurally similar to thymidine, one of the building blocks of DNA. BrDU gets incorporated into DNA instead of thymidine, but it can only get into cells that are replicating. Therefore, measuring the proportion of cells with BrDU indicates how many cells are replicating. HIV-infected patients 18 years of age and older may be eligible for this study. Candidates will be screened with a medical history, physical examination, chest X-ray, electrocardiogram (EKG) and blood tests. Participants will be given an infusion of BrDU through a catheter (thin plastic tube) placed in an arm vein. Blood will be drawn up to 4 times in the first 24 hours after the infusion. Additional samples will then be collected as often as daily for the first week, twice a week for the next 3 weeks and then weekly to monthly for up to 1 year. Some patients may undergo a tissue biopsy (removal of a small tissue sample from a lymph node, tonsil or colon) or computed tomography (CT) scans of the thymus (a small gland between the lungs that manufactures lymphocytes. Some patients will have a second infusion in order to examine changes in the rate of CD4 replication over time or following potent antiretroviral therapy. Patients will be followed in the clinic periodically for the first year and then will be seen in the clinic or contacted by telephone once a year for 4 more years. The results of this study may provide a better understanding of how HIV causes disease and how therapy affects the immune system.

Studies to assess the effectiveness of interventions to prevent HIV infection depend upon robust estimates of Baseline HIV incidence rates. The changing landscape of high-risk populations, as well as the evolution of biomedical pre-exposure prophylaxis (PrEP) interventions, requires a contemporary evaluation of HIV incidence as well as demographic, behavioral and other subject factors which may impact HIV incidence. This is a prospective cohort study to measure HIV-1 seroincidence in a study population of HIV-1 uninfected Chinese men who have sex with men (MSM) and transgender women (TGW) who are at high-risk of HIV infection. Approximately 550 subjects who are male sex at birth and have sex with men shall enter the study, which will allow for a 10% drop out rate to maintain 500 subjects at the conclusion of the cohort. This is a single arm cohort study to determine HIV-1 seroincidence rates in high risk MSM and TGW when combined with a comprehensive prevention package including HIV and safe sex counseling, provision of condoms and water-based lubricant, and sexually transmitted infection (STI) screening and referral for treatment. It will be determined what proportion of high-risk MSM and TGW who are given a comprehensive HIV-1 prevention package will acquire HIV-1 infection.

HIV virus is an etiologic agent of ( AIDS ) immunodeficiency syndrome . It is known that the estimated rate of transfer from mother to baby is 25% to 45%, pregnancy rate is 5-10%, pregnancy rate is 15-20% and in lactation period is 5-10%. Risk factors; maternal viral load, breastfeeding, vaginal birth, and prematurity. Although there is a high rate of false positivity in prenatal screening in our country, one of the factors affecting this is the number of pregnancies.
