The Management of Diabetes with Hyperuricemia: Can We Hit Two Birds with One Stone?

Serum urate (SU) is an independent predictor for the incidence of diabetes. In current diabetes treatment regimens, there is insufficient appreciation of the importance of hyperuricemia (HU) in disease control and prevention. To summarize the updated knowledge on the effects of SU on β-cell function, insulin resistance and chronic diabetic complications, as well as to evaluate the management of patients with both HU and diabetes, we searched the MEDLINE PubMed database, and included 285 journal articles. An inverted U-shaped relationship between fasting plasma glucose and SU levels was established in this review. Elevated SU levels may enhance the development of chronic diabetic complications, including macrovascular and microvascular dysfunction. Diet and exercise are essential parts of the lifestyle changes necessary for HU and diabetes management. Glucose- and urate-lowering drug selection and combination should be made with the principle of ameliorating, and at least not deteriorating, diabetes and HU. Medical artificial intelligence technology and monitoring systems can help to improve the effectiveness of long-term management of HU and diabetes through digital healthcare. This study comprehensively reviews and provides a scientific and reliable basis for and viewpoints on the clinical management of diabetes and HU.

Nurse-led care is preferred over GP-led care of gout and improves gout outcomes: results of Nottingham Gout Treatment Trial follow-up study

OBJECTIVES

To explore patient satisfaction, gout knowledge, medication adherence and flares among participants receiving nurse-led or general practitioner (GP)-led care of gout in the Nottingham Gout Treatment Trial phase-II (NGTT-II).

METHODS

A total of 438 participants of NGTT-II were sent a questionnaire enquiring about gout knowledge, satisfaction with health-care practitioner, urate-lowering treatment being undertaken, and gout flares ⩾1 year after their final visit. Nurse-led care participants were asked about their preference for receiving gout treatment from either a GP or a nurse.

RESULTS

Completed questionnaires were returned by 82% of participants. Participants previously receiving nurse-led care reported greater satisfaction with health-care practitioner (P < 0.001), had better gout knowledge (P = 0.02), were more likely to be taking urate-lowering treatment [adjusted relative risk (95% CI) 1.19 (1.09, 1.30)], and self-reported fewer flares in the previous 12 months [median (inter-quartile range) 0 (0-0) vs 1 (0-3), P < 0.001] than those receiving GP-led care. Of participants receiving nurse-led care, 41-63% indicated preference for receiving gout treatment from a nurse, while only 5-20% indicated preference for receiving treatment from GPs.

CONCLUSION

The results of this study favour nurse-led care, involving individualized patient education and engagement and a treat-to-target strategy, in terms of patient acceptability, long-term adherence, and flares. Further research is required to evaluate the feasibility of implementing such a model of care in clinical practice.

Increasing trend of asymptomatic hyperuricemia under treatment with urate-lowering drugs in Japan

Objectives: To describe recent trends in the prevalence of gout and asymptomatic hyperuricemia regarding urate-lowering treatment (ULT) in Japan. Methods: A database of health insurance claims managed by the Japan Medical Data Center was used to estimate the annual prevalence of gout and asymptomatic hyperuricemia during 2010-2014. ULT was evaluated for status of the two diseases during the same period. The significance of time trends was evaluated by Cochrane-Armitage trend test. Results: The prevalence of physician-diagnosed gout in men aged 20-64 years was 1.54% (95% CI: 1.49%-1.58%) in 2010, with a slight but significant (p < 0.001) annual increase, up to 1.66% (95% CI: 1.62%-1.71%) in 2014. In women, gout prevalence was somewhat constant about 0.09% during 2010-2014. Among male patients with gout, 78% received ULT. The prevalence of male patients with asymptomatic hyperuricemia in the same age range, who received ULT, increased significantly from 1.77% (95% CI: 1.72%-1.81%) to 2.14% (95% CI: 2.09%-2.19%) during 2010-2014 (p < 0.001). Conclusion: Gout prevalence in adult men in Japan has increased significantly in recent years. The prevalence of asymptomatic hyperuricemia under ULT has also increased significantly and was higher than that of gout.

Gout - a guide for the general and acute physicians

Gout is the most prevalent inflammatory arthritis and affects 2.5% of the general population in the UK. It is also the only arthritis that has the potential to be cured with safe, inexpensive and well tolerated urate-lowering treatments, which reduce serum uric acid by either inhibiting xanthine oxidase - eg allopurinol, febuxostat - or by increasing the renal excretion of uric acid. Of these, xanthine oxidase inhibitors are used first line and are effective in 'curing' gout in the vast majority of patients. Gout can be diagnosed on clinical grounds in those with typical podagra. However, in those with involvement of other joints, joint aspiration is recommended to demonstrate monosodium urate crystals and exclude other causes of acute arthritis, such as septic arthritis. However, a clinical diagnosis of gout can be made if joint aspiration is not feasible. This review summarises the current understanding of the pathophysiology, clinical presentation, investigations and treatment of gout.
