Management of Pedal Edema in Patients with History of Fever and S. Typhi Infection

Initial Assessment

• Evaluate the severity of edema, especially if grade 3-4 (≥6 mm pit lasting >1 minute after compression), as this affects the treatment approach, according to the Kidney International guidelines 1
• Rule out other causes of edema, including heart failure, venous insufficiency, and medication-induced edema, as recommended by Clinical Infectious Diseases and other guidelines 2, 3

Monitoring and Treatment Approach

• Monitor for electrolyte abnormalities, especially hyponatremia and hypokalemia, during diuretic treatment, as advised by Hypertension guidelines 4
• Assess clinical response through weight loss (target 0.5-1 kg/day depending on severity) and monitor serum electrolytes, creatinine, and blood pressure closely during treatment, as suggested by guidelines 5

Treatment Adjustments

• If furosemide fails to control edema, consider adding a thiazide diuretic for sequential nephron blockade, or switching to ACE inhibitors or ARBs for patients with calcium channel blocker-induced edema, as recommended by guidelines 3, 5
• Consider spironolactone (aldosterone antagonist) as an add-on therapy for resistant edema, according to guidelines 5

Cautions and Discontinuation

• Discontinue diuretics if severe hyponatremia, progressive renal failure, or incapacitating muscle cramps develop, as advised by guidelines 5
