Objective: To provide guidance for the management of gout, including indications for and optimal use of urate‐lowering therapy (ULT), treatment of gout flares, and lifestyle and other medication recommendations.Methods: Fifty‐seven population, intervention, comparator, and outcomes questions were developed, followed by a systematic literature review, including network meta‐analyses with ratings of the available evidence according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology, and patient input. A group consensus process was used to compose the final recommendations and grade their strength as strong or conditional.Results: Forty‐two recommendations (including 16 strong recommendations) were generated. Strong recommendations included initiation of ULT for all patients with tophaceous gout, radiographic damage due to gout, or frequent gout flares; allopurinol as the preferred first‐line ULT, including for those with moderate‐to‐severe chronic kidney disease (CKD; stage >3); using a low starting dose of allopurinol (≤100 mg/day, and lower in CKD) or febuxostat (<40 mg/day); and a treat‐to‐target management strategy with ULT dose titration guided by serial serum urate (SU) measurements, with an SU target of <6 mg/dl. When initiating ULT, concomitant antiinflammatory prophylaxis therapy for a duration of at least 3–6 months was strongly recommended. For management of gout flares, colchicine, nonsteroidal antiinflammatory drugs, or glucocorticoids (oral, intraarticular, or intramuscular) were strongly recommended.Conclusion: Using GRADE methodology and informed by a consensus process based on evidence from the current literature and patient preferences, this guideline provides direction for clinicians and patients making decisions on the management of gout.

Objective: To study 5 type I interferon (IFN)–inducible genes (LY6E, OAS1, OASL, MX1, and ISG15) in patients with systemic lupus erythematosus (SLE) and to correlate expression levels with disease activity and/or clinical manifestations.Methods: Peripheral blood cells were obtained from 48 SLE patients, 48 normal controls, and 22 rheumatic disease controls, and total RNA was extracted and reverse transcribed into complementary DNA. Gene expression levels were measured by real‐time polymerase chain reaction, standardized to a housekeeping gene, and summed to an IFN score. Disease activity was determined by the Safety of Estrogens in Lupus Erythematosus: National Assessment–Systemic Lupus Erythematosus Disease Activity Index (SELENA‐SLEDAI) composite.Results: Each gene was highly expressed in SLE patients compared with normal controls (P ≤ 0.0003) or disease controls (P ≤ 0.0008 except for MX1). IFN scores were positively associated with the SELENA‐SLEDAI instrument score (P = 0.001), the SELENA‐SLEDAI flare score (P = 0.03), and the physician's global assessment score (P = 0.005). Compared with patients without nephritis, lupus nephritis patients had higher IFN scores (overall P < 0.0001), especially during active renal disease. IFN scores were weakly associated with neurologic manifestations. Elevated IFN scores were positively associated with the current presence of anti–double‐stranded DNA (anti‐dsDNA) antibodies (P = 0.007) or hypocomplementemia (P = 0.007). LY6E expression levels distinguished active from inactive lupus nephritis (P = 0.02) and were positively associated with proteinuria (P = 0.009).Conclusion: The 5 IFN‐inducible genes were highly expressed in SLE patients, and increased levels were correlated with disease activity defined by several methods. IFN scores, or LY6E levels, were elevated in lupus nephritis patients, especially during active renal disease, and in patients with anti‐dsDNA antibody positivity and hypocomplementemia. IFN scores, or LY6E levels, may be useful as a biomarker for lupus nephritis therapy.
