GOUT

Gout is a condition that resulted from deposition of monosodium urate crystals in various tissues (eg joints, connective tissue, kidney).
The patient experiences acute and chronic arthritis, soft tissue inflammation, tophus formation, gouty nephropathy and nephrolithiasis.
Primary hyperuricemia occurs when uric acid saturation arises without coexisting diseases or drugs that alter uric acid production or excretion, while secondary hyperuricemia is a condition where excessive uric acid production or diminished renal clearance occurs as a result of a disease, drug, dietary product or toxin.

Gout Signs and Symptoms

Signs and Symptoms

Definition

Gout is a condition wherein there is increased uric acid or urate in the body, also called hyperuricemia, that leads to deposition of monosodium urate monohydrate crystals in various tissues (eg joints, connective tissue, kidney)

Pathophysiology

Hyperuricemia is a necessary precondition for the development of monosodium urate monohydrate crystal deposition but this has to be distinguished from gout, the clinical syndrome
Results in acute and chronic inflammation associated with changes in articular and periarticular structures

Epidemiology

Affects up to 1-2% of adults and is the most common inflammatory arthritis in men
Prevalence of gout in the Asia-Pacific region varies
- Ethnic groups in China and Malaysia (eg Malays, Tamils) were found to have higher uric levels as compared to the Japanese and Thai
- Taiwan is one of the countries in the world with highest prevalence of gout

Risk Factors

Risk factors for gout and associated comorbidity should be assessed

Risk Factors Associated with Gout

Hyperuricemia
- Single most important risk factor for developing gout
Male sex
Menopausal women
Age
Purine-rich diet (eg meat, seafood)
Alcohol intake
Diuretic use
Other drug use (eg low-dose Aspirin, antihypertensive medications, Ciclosporin)
Lead exposure

Metabolic Abnormalities Associated with Gout

Hypertension
Obesity
Dyslipidemia
Hyperglycemia and insulin resistance

Comorbidities Associated with Gout

Coronary artery disease
Type 2 diabetes mellitus

Pembrolizumab + chemo improves PFS in previously untreated, advanced TNBC

Christina Lau, 4 days ago

Pembrolizumab in combination with chemotherapy significantly improves progression-free survival (PFS) vs chemotherapy alone in patients with previously untreated, locally recurrent inoperable or metastatic triple-negative breast cancer (TNBC), results of the KEYNOTE-355 study have shown.
