NCT ID: NCT06448195 Recruiting - Clinical trials for Growth Hormone Treatment

Effects of Growth Hormone Therapy on Metabolic Function in Fatty Liver Post-Pituitary Adenoma Surgery

Start date: January 1, 2023
Phase: Phase 4
Study type: Interventional

Growth Hormone (GH) is essential for maintaining fat, muscle, bone, and energy balance. Adult Growth Hormone Deficiency (GHD) affects about 0.3% of adults. GHD, common post-pituitary tumor surgery or radiotherapy, disrupts lipid metabolism, increasing triglycerides and low-density lipoprotein cholesterol while decreasing high-density lipoprotein cholesterol. This is especially severe in GH adenoma patients, whose lipid metabolism issues worsen post-surgery, increasing the risk of atherosclerosis. Fat accumulates in the liver first, making liver fat content a key early indicator of metabolic disorders, which can lead to diabetes and atherosclerosis. Early intervention is crucial as liver fat deposition in Nonalcoholic Fatty Liver Disease (NAFLD) is reversible. Recombinant human growth hormone can treat GHD-related lipid metabolism disorders, but research on its effects on liver fat in post-surgery GH adenoma patients is limited. The investigators plan to treat these patients with 1 mg/week of recombinant human growth hormone for 24 weeks, aiming to normalize insulin-like growth factor-1 levels. Liver fat content changes will be measured using proton magnetic resonance spectroscopy (1H MRS) and Fibroscan. Changes in weight, BMI, waist circumference, fasting blood glucose, blood lipids, and other metabolic factors will also be evaluated to assess treatment efficacy and safety. Zhongshan Hospital, affiliated with Fudan University, performs over 300 pituitary tumor surgeries annually, including 100 GH adenoma cases. The hospital has extensive experience and can enroll 40 patients. The Endocrinology Department excels in evaluating lipid metabolism disorders in NAFLD using non-invasive methods. As a major hospital in Shanghai, it has ample patients to meet study requirements. Detailed exit criteria and rescue plans have been established to address potential adverse events during the study.

NCT ID: NCT06447870 Recruiting - Clinical trials for Inflammatory Bowel Diseases

Research on the Mechanisms of Treatment Non-response in Inflammatory Bowel Disease Based on Multi-omics Technology

Start date: December 1, 2023
Phase:
Study type: Observational

In recent years, biologic agents such as infliximab, vedolizumab, and ustekinumab have demonstrated tremendous potential in the treatment of inflammatory bowel disease (IBD), altering the traditional treatment paradigm for IBD. Despite their significant efficacy, there remains a subset of patients who do not respond to biologic agents, necessitating research into the response mechanisms of biologic therapy to explore more precise treatment strategies. Preliminary work by the principal investigator has identified multiple potential responder cell subtypes to biologic agents, which may be influenced by the gut and oral microbiota. Therefore, this project proposes to investigate the mechanisms of response to biologic agents, aiming to explore more precise treatment strategies, through the integration of single-cell transcriptomics, 16S rRNA, and other multi-omics technologies on tissue samples, feces, saliva, peripheral blood, etc., from IBD patients before and after treatment. This will involve integrating bioinformatics analysis and in vitro/in vivo functional validation to elucidate the roles of treatment-responsive cell subtypes and gut and oral microbiota in the inflammatory microenvironment of the intestine, with the aim of uncovering the mechanisms of biologic agent therapy and providing new clues for the development of next-generation drug targets.

NCT ID: NCT06447740 Recruiting - Clinical trials for Renal Artery Stenosis Atherosclerotic

Fractional Flow Reserve-guided Stenting Versus Medical Therapy in Atherosclerosis Renal Artery Stenosis

FAIR
Start date: June 3, 2024
Phase: N/A
Study type: Interventional

Although randomized trials have demonstrated there is no benefit of renal-artery stenting in addition to medical therapy for patients with atherosclerosis renal artery stenosis, many patients indeed gained benefit in daily practices after stenting, such as reduction in blood pressure and recovery in renal functions. One important gap is that there is no universal standard to determine whether to stent in these patients. Fraction Flow Reserve (FFR) has been studied for many year in chronic coronary heart disease and FFR-guided revascularization strategy is known to be better than both angiography-guided revascularization and medication alone. Based on the primary finding of FAIR-pilot study (NCT05732077), FFR-guided renal artery stenting is practical. The overall purpose of the FAIR trial is to compare the clinical outcomes and safety of FFR-guided stenting plus optimal medical treatment (OMT) versus OMT alone in patients with renal-vascular hypertensive patients. With the 'all comers' design, participants met the inclusive/exclusive criteria will be enrolled, and hyperemic FFR induced by dopamine will be measured in all participants. If FFR is ≥0.80, patients will be treated with OMT alone and follow up. If FFR is <0.80, participants will be randomized to stenting in the renal artery plus OMT or OMT alone on a 1:1 ratio. The blood pressure and anti-hypertensive medications will be compared before and 3 months after the procedure based on ambulatory blood pressure monitoring, all participants will be followed up for 1 year.

Start date: September 1, 2022
Phase:
Study type: Observational

This study aims to collect clinical, laboratory, and imaging data from patients with unruptured intracranial aneurysms, and collect blood or urine samples for cotinine testing. The enrolled patients underwent high-resolution magnetic resonance angiography to detect whether the intracranial aneurysm wall was enhanced and classify the degree of enhancement. The purpose is to study the correlation between arterial aneurysm wall enhancement and cotinine levels
