Filter by:This is a prospective, multicenter, non-interventional study. Findings are analyzed using epidemiological methods.
Aim of the work 1. Assessment of hepatic affection in patients with ESRD (end stage renal disease) on regular dialysis with iron indices suggesting iron overload. 2. Comparison between HCV -negative HD patients with high and normal TSAT as regard liver iron concentration(LIC) and degree of fibrosis.
1. Primary objectives: • To evaluate the safety and efficacy of long-term orally administration of CN128 in thalassaemia patients with blood transfusion dependent and aged 16 and above. 2. Design: - The study is designed as a single arm and opened phase IIa clinical trial, so as to investigate the safety and efficacy of CN128. - A total of 50 eligible subjects are planned to be enrolled, and orally administration of CN128 for 24 weeks or 48 weeks according to the administration plan. The treatment period is from day 0 to 24 weeks, and the extended treatment period was from 25 weeks to 96 weeks. - Subjects' medication status, uncomfortable symptoms, concomitant medication or non-drug therapy were recorded daily. 3. Subject inclusion criteria: - Thalassemia patients. - The number of blood transfusion per month ≥1. Or hemoglobin can not be maintained at 90g/L above, if blood transfusions is less than once per month. - Serum ferritin ≥ 500 µg/L - Patients aged 16 and above - Volunteer for the trial and sign the informed consent. 4. Subject exclusion criteria: - Active hepatitis B (HBsAg positive, HBsAb negative) or hepatitis C (HCV antibody positive, detectable HCV RNA, and alanine transaminase (ALT) beyond normal range) - Active gastrointestinal disease history (including: gastric ulcer, duodenal ulcer, stomach or esophageal varices, ulcerative colitis, Crohn's disease, gastrointestinal cancer, familial genetic multiple intestinal polyps), and History of gastrointestinal perforation, gastrointestinal surgery that influence drug absorption, and other potential intestinal complications considered by researchers; - ALT or Aspartate transaminase (AST) > 2.5 × Upper limit of normal (ULN), or serum creatinine > 1.5 × ULN; - Neutropenia patient (neutrophil count < 1.5 × 109 / L); - Active infection uncontrolled; - The patients who are currently taking CYP3A strong inducer or strong inhibitor drugs, or the drug that may extend the QT interval, or the drug that may decrease neutrophil count, but can not temporarily interrupt the use of such drugs; - Congenital long QT syndrome or known family history of long QT syndrome; QTc > 480 ms; clinically significant ventricular or atrial fast arrhythmia; - The patients who can not accept MRI as detection means, such as claustrophobic for MRI, pacemaker, and those using ferromagnetic metal implants. - Birth planner (including male subjects) within or within 3 months after the end of the trial; - Participated in other clinical trials in the three months before taking the test preparation, except for non-interventional studies; - Pregnant or lactating women; - Unsuitable to participate in the trial considered by the researchers. 5. Usage: - All subjects will be given the lower (10 mg/kg bw, bid) or higher dose (15 mg/kg bw, bid) for 24 or 48 weeks, according to the administration plan. - All subjects will be given the lower (15 mg/kg bw, bid) or higher dose (20 mg/kg bw, bid) for 49 or 96 weeks, according to the administration plan. 6. Safety assessments: Safety evaluations include adverse events, adverse reactions, severe adverse events, and severe adverse reactions; growth (weight, height); total and free testosterone in men, follicle-generating hormone and luteinizing hormone in women; vital signs and electrocardiogram; hearing, laboratory tests (blood routine analytes, blood biochemistry, coagulation function, thyroid and para-thyroid function, urine routine analytes.), urine pregnancy test (women of childbearing age),Levels of drug exposure during the study. 7. Efficacy assessments: Efficacy evaluations include serum ferritin, liver iron content (MRI R2) and cardiac iron content (MRI T2*). 8. Statistics: - Subject characteristic distribution Demographic characteristics, general conditions, and baseline conditions (pre-treatment) of enrolled subjects were analyzed.The measurement data are described by means, standard deviation, minimum value and maximum value, while the qualitative data list frequency and percentage. - Safety analysis Descriptive statistical analysis was used for safety endpoints. - Effectiveness analysis Mean, standard deviation, median, minimum and maximum values were described and 95% confidence intervals were calculated. Paired T-test was used to compare each time point with the baseline if necessary. The 95% confidence interval was calculated by using Clopper-Pearson method for the proportion of patients.
A national survey on the prevalence and natural history of endocrine complications in thalassemia transfusion--dependent patients treated with deferasirox was designed, in order to assess a larger population during a longer follow up and improve the quality of previous investigations.
The aim of the present study is evaluating the strength of combination therapy of hydroxy urea, omega 3, nigella sativa and honey on antioxidant-oxidant status (OXIDATIVE STRESS) in response to reactive oxygen species production (LIPID PEROXIDATION) and their effect on iron intoxication (IRON CHELATION) in pediatric major thalassemia.
The effect of N-acetylcysteine as antioxidant and its effect on pretransfusion hemoglobin and iron overload in patients with thalassemia were compared to patients who didn't receive n-acetylcysteine after 3 months of study duration
The objective of this study is to examine patient-reported gastrointestinal side effects, as well as iron status indicators, inflammatory markers and oxidative stress following administration of ferrous sulfate and iron-enriched Aspergillus oryzae supplementation.
Polyphenolic compounds are very strong Inhibitors of non-heme iron absorption, as they form insoluble complexes with ferrous iron. Patients with hereditary hemochromatosis (HH) have an increased intestinal non-heme iron absorption due to a genetic mutation in the regulatory pathway, leading to excess iron in the body. This study investigates the inhibitory effect of a natural polyphenol Supplement in participants with HH.
A prospective, mono-center, interventional study evaluating the effect of one year initial care by hygieno-dietary advices with or without Phlebotomy on glycemia after at least 5 years in Patients with dysmetabolic iron overload syndrome
Safety, tolerability, and acceptability of twice-daily dosing with deferiprone delayed-release (DR) tablets in patients with systemic iron overload.
