Acute flaccid paralysis in Indonesian adult due to suspected familial hypokalemia paralysis: A rare case

Background: Familial hypokalemic periodic paralysis (FHPP) is rare, so its management is essential to report. Case presentation: A 25-year-old Indonesian woman complained of feeling weak in both hands and legs, but the heaviest in both legs. The patient has several family members with similar complaints. The patient experienced decreased muscle strength in the upper extremity of 4/4 and the lower extremity of 3/3. Laboratory investigation showed potassium of 2.0 mmol/L, and the patient was given KCL of 50 mEq/24 hours, KSR of 3 × 600 mg/24 hours for 3 days, and a high potassium diet. The next few days, potassium levels increased, and the patient was treated as an outpatient. Discussion: Early diagnosis and management of acute flaccid paralysis (AFP) due to FHPP are very effective in low-resource settings. Conclusion: Finding the cause of AFP is essential for better management.
