What is the recommended management for axial gout in post-hysterectomy Canadian Muslim women adhering to halal dietary customs, with or without Premarin (conjugated estrogens) treatment?

Management of Axial Gout in Post-Hysterectomy Muslim Women Adhering to Halal Dietary Customs

Premarin (conjugated estrogens) is acceptable for Muslim women who adhere to Halal dietary customs, as the management of axial gout should prioritize urate-lowering therapy with allopurinol as first-line treatment regardless of hormonal status. 1

Understanding Axial Gout in Post-Hysterectomy Women

• Axial gout (affecting the spine) is a less common manifestation of gout that can lead to significant spinal bone damage if left untreated, including erosion of vertebral endplates 1
• Post-hysterectomy women may have altered hormonal profiles that could influence uric acid metabolism, but the primary treatment approach remains focused on urate-lowering therapy 1
• The management strategy should address both the immediate symptoms and long-term prevention of bone damage through proper urate control 1

First-Line Treatment for Axial Gout

• Allopurinol is recommended as first-line urate-lowering therapy (ULT) for patients with normal kidney function, starting at a low dose of 100 mg/day and gradually increasing by 100 mg increments every 2-4 weeks until reaching the target serum uric acid level 1, 2
• The target serum uric acid level should be maintained below 6 mg/dL (360 μmol/L) for most patients, and below 5 mg/dL (300 μmol/L) for patients with severe gout (including tophaceous gout) until resolution 1, 3
• For acute flares, oral colchicine (up to 2 mg daily) and/or NSAIDs are first-line agents for systemic treatment 1, 4

Considerations for Muslim Women Following Halal Dietary Customs

• Premarin (conjugated estrogens) is derived from pregnant mare's urine, which raises potential religious concerns for some Muslim women adhering to halal dietary customs 1
• However, there is no specific prohibition in guidelines against using Premarin in the context of gout management for Muslim women 1
• When medication is medically necessary and no halal alternatives exist, many Islamic scholars permit its use under the principle of necessity (darura) 3

Lifestyle Modifications for Gout Management

• Every person with gout should receive lifestyle advice including weight loss if appropriate, avoidance of alcohol (especially beer and spirits), sugar-sweetened drinks, and excessive intake of meat and seafood 1
• Low-fat dairy products should be encouraged as they have been associated with lower urate levels 1, 5
• Regular exercise is recommended to improve overall health and potentially decrease mortality associated with chronic hyperuricemia 1, 6

Management of Concurrent Medications

• If the patient is taking hydrochlorothiazide, consider switching to an alternate antihypertensive when feasible 1
• Losartan is preferentially recommended as an antihypertensive agent when feasible due to its uricosuric effects 1
• For hyperlipidemia, fenofibrate may be beneficial as it can also reduce serum uric acid levels 1

Monitoring and Follow-up

• Serum uric acid levels should be monitored regularly and maintained below target levels lifelong 1, 3
• Estimated glomerular filtration rate (eGFR) should be calculated at diagnosis and monitored regularly alongside serum uric acid measurements 1, 3
• Associated comorbidities such as hyperlipidemia, hypertension, hyperglycemia, and obesity should be addressed as an important part of gout management 1, 3

Special Considerations for Axial Involvement

• For axial gout specifically, more aggressive urate-lowering therapy may be needed to prevent spinal bone damage 1
• If allopurinol fails to achieve target uric acid levels or is not tolerated, febuxostat or a uricosuric agent should be considered as alternative options 1
• In patients with severe, debilitating tophaceous gout that does not respond to conventional therapy, pegloticase may be considered 1

Prophylaxis When Starting ULT

• When initiating urate-lowering therapy, prophylaxis against flares is essential using colchicine (up to 1.2 mg daily), or if contraindicated, NSAIDs or low-dose glucocorticoids 1, 4
• Patient education on the risk and management of flares during ULT initiation is essential 1
