Filter by:Phase 4, open-label, two-year, prospective, multi-center, follow-up study conducted at up 15 sites in USA. Approximately 1,000 patients with moderate-to-severe CKD will be enrolled and followed for up to 24 months.
The primary objective of this study is to determine any causative or associated factors for the development of Nephrogenic Systemic Fibrosis (NSF), Nephrogenic Fibrosing Dermopathy (NFD), or related diagnosis. Our primary focus will be on the previous administration of gadolinium to these patients, but we will also look at other postulated causes and risk factors. The secondary objective of this study is to assess tissue gadolinium (Gd) levels in five groups of subjects: - Those affected by NSF. - Those with normal kidney function who have undergone a medical imaging procedure using Gd-based contrast agent (GBCA) in the 2 years prior to a skin biopsy. - Those with normal kidney function who have never been exposed to GBCA and have had a skin biopsy. - Those on dialysis or with eGFR ≤ 30 ml/min/1.73 m2 who have had a medical imaging procedure using GBCA in the 2 years prior to skin biopsy. - Those on dialysis or with eGFR ≤ 30 ml/min/1.73 m2 who have never been exposed to GBCA and have had skin biopsy. We hypothesize that there is a correlation between the administration of Gd-containing agents usually associated with MRI procedures and the development of NSF in those with renal failure and some other predisposing condition. We also hypothesize that tissue Gd levels in those with NSF will be higher than in those who have been exposed to GBCA but do not have NSF. Of the two groups without NSF but with exposure to GBCA, we hypothesize that those with kidney dysfunction will have higher tissue Gd levels than those with normal kidney function. We hypothesize that in the two groups of subjects without exposure to GBCA, there will be no detectable levels of Gd, regardless of kidney function status.
The investigators will study the effect of imatinib mesylate (Glivec) in treatment of moderate to severe nephrogenic systemic fibrosis (NSF). So far there is no evidence of adequately effective treatment options of NSF. Various treatments have been tried to stop the progressing disease. Corticosteroids, which suppress the early inflammatory stage of the disease, fail to halt disease progression. Other immunosuppressive agents, photopheresis, and kidney transplantations are reported to be partly beneficial to the patients. It has not been possible to confirm these findings in further studies because in photopheresis, and kidney transplantation, such effects are generally unreproducible.
Patients with moderate to severe renal impairment scheduled for a magnetic resonance imaging (MRI) scan and injection with a contrast agent, Primovist/Eovist, will be asked to participate. The administration of contrast agents that contain gadolinium such as Primovist/Eovist might increase a potential risk to develop a rare condition called nephrogenic systemic fibrosis (NSF) in patients with renal impairment. This study is to assess the potential risk to develop NSF in patients with renal impairment after the administration of Primovist/Eovist. Patients who are enrolled in this study will receive a Primovist/Eovist enhanced MRI scan which was prescribed by the referring doctor. After the MRI scan the patient will be included in a two year follow-up period to assess if signs or symptoms suggestive of NSF have appeared.
The Primary Aim of this study is to validate a questionnaire as a screening tool to identify subjects with symptoms suggestive of nephrogenic systemic fibrosis (NSF). The investigators believe that there will be difference between subjects with NSF and other skin conditions and normal skin.
Patients with moderate to severe renal impairment scheduled for a magnetic resonance imaging (MRI) scan and injection with a contrast agent, Gadovist, will be asked to participate. The administration of contrast agents that contain gadolinium such as Gadovist might increase a potential risk to develop a rare condition called nephrogenic systemic fibrosis (NSF) in patients with renal impairment. This study is to assess the potential risk to develop NSF in patients with renal impairment after the administration of Gadovist. Patients who are enrolled in this study will receive a Gadovist enhanced MRI scan which was prescribed by the referring doctor. After the MRI scan the patient will be included in a two year follow-up period to assess if signs or symptoms suggestive of NSF have appeared.
The objective of this long term study is to prospectively evaluate the incidence of NSF in patients with severe CKD or kidney failure including patients undergoing dialysis (stages 4 and 5 i.e., with an eGFR below 30)who have not had exposure to a GBCA within 10 years prior to enrollment.
Assess potential risk for NSF in subjects with renal impairment (moderate) post magnevist injection. Subjects will be screened within 48 hours of previously scheduled MRI, those meeting the enrollment criteria will be enrolled prior to MRI and followed for 2 years post MRI with visits occuring at 1yr and 2 yr timepoints, in addition follow-up phone calls conducted at 1, 3, 6 and 18 months to assess for skin changes suggestive of NSF.
The objective of this long-term study is to prospectively compare the incidence of NSF in two cohorts (Cohort 1 - patients with moderate chronic kidney disease eGFR 30 to 59 and Cohort 2 - patients with severe chronic kidney disease or kidney failure eGFR <30).
