Filter by:Human papillomavirus (HPV) affects a significant number of transplant patients. In women, human papillomavirus (HPV) causes genital warts, pre-cancerous areas of the cervix, and cervical cancer. In men, the virus can cause warts of the anal and genital areas. Men can also sexually transmit the virus to their partners. A patient who has had an organ transplant is at higher risk of infections as well as cancers because of the lifelong immune suppressive medications. HPV vaccination is effective in the prevention of cervical cancer and is now recommended for all females aged 9-26 years by Alberta Health and Wellness and the Canadian National Advisory Committee on Immunization (NACI). However, how well the vaccine works in transplant patients is not known. This study is being done to look at response of the immune system to HPV vaccine in men and women up to the age of 35 who have had an organ transplant. Men are also included in this study because they have the potential to get anal / genital warts and transmit the virus to their partners. The total duration of the study is three years. Fifty female and male solid organ transplant recipients (lung, heart, liver, kidney, pancreas, small bowel or combined organ transplants) on immunosuppression will be enrolled in the study.
Cytomegalovirus (CMV) is the most common viral infection in patients who have undergone a transplant.Serious infections due to CMV can affect many parts of the body including the lungs, the gut, and the liver. The purpose of this study is to assess how the virus interacts with the patient's immune system, so that in the future it may be possible to develop better ways to prevent and treat the virus infection.
The purpose of this study is to understand how the pancreas functions after transplantation and particularly why high blood sugar levels develop. It will also analyze the effect of the medicines used to prevent rejection on blood sugar levels. The hypothesis to be tested is that hyperglycemia more than six months after successful pancreas transplant results from a defect in insulin secretion, insulin resistance, or both.
Cytomegalovirus (CMV) is a common cause of illness in patients who have undergone a transplant. Serious infections due to CMV can affect many parts of the body including the lungs, the gut, and the liver. Since transplant recipients are at risk for CMV or have evidence of infection with CMV, they are given an antiviral drug (usually ganciclovir or valganciclovir). Despite this, there are a chance that CMV infection may cause problems in the future. The purpose of this study is to assess how well patients'immune systems responds to the CMV virus, so that in the future it may be possible to predict which patients are at highest risk of CMV.
Human herpesvirus-6 (HHV-6) and -7 (HHV-7) infections are common after transplantation. Such infections may predispose transplant patients to other infections, contribute to a recurrence of hepatitis C virus, and affect rejection and function of the transplanted liver. Given the significant clinical impact of these viruses, routine laboratory monitoring may be beneficial by identifying patients who have persistent or high levels of infection. In these patients, immunosuppressive medications could be adjusted, or antiviral medications administered. There are currently no randomized trials that address this important question. This prospective, randomized trial will analyze whether routine laboratory monitoring for HHV-6 and -7 is clinically useful, and whether it would improve overall outcomes in transplant recipients.
The trial will compare a group of patients whose immune system is primed with the pneumococcal conjugate vaccine and then given a boost with polysaccharide vaccine (prime-boost strategy) vs. a group vaccinated with the standard 23-valent polysaccharide vaccine alone. It is hypothesized that the conjugate vaccine priming will provide an enhanced response in these immunosuppressed individuals who may respond poorly to standard vaccination.
