Available recombinant uricases (rasburicase, pegloticase) are potent hypouricaemic agents for tophaceous gout, but their long-term use is in question. We have performed a literature review on uricases, using Scirus, PubMed, Science Direct, and several other search engines. We have also consulted the records of drug regulatory authorities and patents on uricases. Rasburicase (Fasturtec(®)) was approved in Europe for tumour lysis syndrome induced by chemotherapy, in a single daily infusion dose for a maximum of 7 days. A retrospective study (n=10) conducted in patients with gout and three clinical cases have shown that infusions spaced over time, over several months, ensure the control of serum uric acid and help to eliminate or significantly reduce the size of tophi. However, repeated gout attacks (despite colchicine) and hypersensitivity reactions (despite corticosteroids) have dampened enthusiasm for its use in gout. Pegloticase was recently approved by the Food and Drug Administration (FDA) for patients with chronic gout, refractory or intolerant to conventional hypouricaemic therapy. A 6 month study versus placebo showed that pegloticase (infused at 8 mg every 2 weeks), induced a significant decrease in plasma uric acid in about 40% of patients (associated with a tendency for tophi dissolution). However, the remaining patients were non-responders, which correlated with the formation of pegloticase antibodies and infusion reactions. Research efforts are needed to develop less immunogenic uricases. In conclusion, some uricases could have an important role in the treatment of gout, for instance as a first-line treatment and over a short period of several months in patients with severe and tophaceous gout to allow rapid tophi dissolution.

Differences between private and public primary health care centers and differences between men and women in antihypertensive care and cardiovascular prevention in all patients with hypertension treated in primary care in Stockholm County, Sweden.
BMC Prim Care
January 2025
Division of Family Medicine and Primary Care, Department of Neurobiology, Care Sciences and Society, Karolinska Institutet, Huddinge, Sweden.
Aims: To study differences in cardiovascular prevention and hypertension management in primary care in men and women, with comparisons between public and privately operated primary health care (PHC).
Methods: We used register data from Region Stockholm on collected prescribed medication and registered diagnoses, to identify patients aged 30 years and above with hypertension. Age-adjusted logistic regression was used to calculate odds ratios (ORs) with 99% confidence intervals (99% CIs) using public PHC centers as referents.

Electronic address:
Background: Our study aims to provide evidence concerning the relationship between hyperuricemia, gout and Vitamin D deficiency by analyzing data from Peking Union Medical College Hospital (PUMCH), the National Health and Nutrition Examination Survey (NHANES) database, and through Mendelian randomization (MR) analyses.
Methods: Sample 1 involved patients from PUMCH (n=13,532), and sample 2 involved participants from NHANES (Unweighted n=22,860; weight n=182,829,142). Logistic regression and restricted cubic spline analyses were applied to assess above relationship.

Background: Aging increases disease susceptibility and reduces vaccine responsiveness, highlighting the need to better understand the aging immune system and its clinical associations. Studying the human immune system, however, remains challenging due to its complexity and significant inter-individual variability.
Methods: We conducted an immune profiling study of 550 elderly participants (≥60 years) and 100 young controls (20-40 years) from the RESIST Senior Individuals (SI) cohort.
Associations of Serum Urate and Cardiovascular Events in a Clinical Trial of Interleukin-1β Blockade.

Center for Cardiovascular Disease Prevention, Divisions of Preventive Medicine and Cardiovascular Diseases, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts, USA.
Background: Serum urate (SU) associates with cardiovascular (CV) events, mortality, and gout.
Objectives: The purpose of this study was to assess whether SU predicts CV risk in a trial of interleukin (IL)-1β inhibition with canakinumab, and whether IL-1β blockade, kidney function, or gout alter these associations.
Methods: This study is a subanalysis of the Canakinumab Antiinflammatory Thrombosis Outcome Study (CANTOS), which randomized 10,061 patients with prior myocardial infarction and elevated high-sensitivity C-reactive protein to 3 doses of canakinumab or placebo.

Gosling gout disease is an infectious disease caused by goose astrovirus (GAstV), which can result in urate deposition in the internal organs and joints of goslings. Since 2015, outbreaks of gosling gout disease have occurred in several goose-producing areas in China. Subsequently, the disease spread to the vast majority of eastern China, becoming a major threat to goose farms and causing huge economic losses to the goose industry.
