Further study details as provided by Mayo Clinic:

Primary Outcome Measures:
  • frequency and severity of muscle cramps in cirrhotic patients reporting the symptom, based on the modified muscle cramps questionnaire (mMCQ) [ Time Frame: 1 month after completion of questionnaire ] [ Designated as safety issue: No ]
    Patients will be given the mMCQ and SF-12 to complete. These instruments will be scored according to established algorithms. Data analysis will include descriptive statistics (frequency, duration and severity of muscle cramps) and correlation between overall quality of life and the mMCQ summary score.


Secondary Outcome Measures:
  • safety and efficacy of HCQ for severe cramping using mMCQ, SF-12, and AE inventory. [ Time Frame: 28 days after first dose ] [ Designated as safety issue: No ]
    The study intervention will include open label HCQ daily, which will be provided for the patients for two weeks. A designated coordinator will contact the patient 2 and 7 days of the study to ask of adverse events and fill out the AE inventory. At the end of the dosing, patients will be asked to return to the clinic for post-intervention assessment, which will include the mMCQ, SF-12, systemic AE inventory, CBC and EKG. Designated coordinator will contact patient again on day 28 of the study to ask mMCQ, SF-12, AE inventory.
