The Influence of Urate-lowering Therapy on Sperm Quality of Male Gouty Patients?A Prospective Cohort Study

Gout is a kind of crystal-associated arthropathy caused by monosodium urate deposition, which is directly related to hyperuricemia caused by purine metabolic disorder and/or decreased uric acid excretion. It belongs to the category of metabolic rheumatism. Gout can be complicated with kidney disease. The severe cases can occur joint destruction, renal function damage, and often accompanied by hyperlipidemia, hypertension, diabetes, arteriosclerosis and coronary heart disease and so on. The prevalence of gout varies greatly from different countries. But on the whole, the prevalence of gout is increasing year by year, and the incidence of gout is getting younger. With the continuous improvement of living standards in today's society, middle-aged men have quietly become a high incidence group of gout. The pathophysiological basis of gout is hyperuricemia, so reducing uric acid is the core of gout treatment. The reducing uric acid in patients with gout is a long-term process, and the drug can not be stopped after the serum uric acid is reduced to normal. Once patients with gout stop taking uric acid-lowering drugs, serum uric acid quickly returns to the pre-treatment level, which can not only cause gout attack again, but also bring the risk of kidney and cardio-cerebrovascular involvement if serum uric acid does not reach the control standard for a long time. Therefore, uric acid-lowering therapy requires the use of a minimum dose of uric acid-lowering drugs to maintain long-term uric acid levels. In recent years, with the aggravation of environmental pollution and the postponement of childbearing age, the incidence of male infertility is increasing year by year. However, there are relatively few studies on the effect of gout caused by hyperuricemia on male sperm quality. With the rejuvenation of gout patients and the long-term nature of uric acid-lowering therapy, the safety of uric acid-lowering drugs in male gout patients of childbearing age during pregnancy is not sure. Coupled with the opening of China's comprehensive second-child policy, more and more male gout patients join this fertility group. Unfortunately, so far, no animal or human trial has observed the effect of uric acid-lowering drugs on sperm quality. For this reason, this study intends to carry out this observational clinical trial to evaluate the effect of long-term use of uric acid-lowering drugs on male sperm quality by collecting relevant data of patients with gout treated with uric acid-lowering drugs. Aim to provide a theoretical basis for the safety of uric acid-lowering drugs during pregnancy.

Identification of New Biomarkers to Promote Personalized Treatment of Patients With Inflammatory Rheumatic Diseases

Introduction: The medical treatment of inflammatory rheumatic diseases has improved dramatically during the last decades primarily due to the introduction of biological disease modifying anti-rheumatic drugs (bDMARDs). However, bDMARD treatment failure occurs in 30-40% of patients due to lack of effectiveness or side effects. The tools to predict treatment outcomes in the individual patient are currently limited. The objective of the present study is to identify diagnostic, prognostic and predictive biomarkers, which can be used to 1) diagnose inflammatory rheumatic diseases early in the disease course with high specificity and sensitivity, 2) improve prognostication or 3) predict treatment effectiveness and tolerability for the individual patient. Methods and analysis: Observational and translational open cohort study with prospective collection of clinical data and biological materials in patients with inflammatory rheumatic diseases treated in routine care. Patients contribute one cross-sectional blood sample (i.e. whole blood, serum, EDTA-plasma and -buffy coat, and blood in PAXgene RNA tubes) and/or are enrolled for longitudinal follow-up upon start of new DMARD (blood sampling after 0/3/6/12/24/36/48/60 months' treatment). Demographics, disease characteristics, comorbidities and lifestyle factors are registered at inclusion; DMARD treatment and outcomes are collected repeatedly during follow-up. Currently (June 2017) >5,000 samples from ?3,000 patients have been collected. Data will be analysed using appropriate statistical analyses. Ethics and dissemination: The protocol is approved by the Danish Ethics Committee and The Danish Data Protection Agency. All participants give written informed consent. Biomarkers will be evaluated and published according to REMARK, STROBE and STARD guidelines. Results will be published in peer-reviewed medical journals and presented at international conferences.
