Participant gender:
All
Summary
Among patients with colchicine-resistant glucocorticoid-dependent idiopathic RP (idiopathic recurrent pericarditis during at least a second recurrence, having met the 2015 European Society of Cardiology criteria for pericarditis at least once), HCQ 400mg daily is associated with a reduce the risk of recurrence. The above hypothesis will be tested with a randomized, prospective, parallel, open label clinical trial. The expected study duration is approximately 12 months from the time the first subject is enrolled (planned for February 2023) to the time of study's termination date (December 2024). The researchers will obtain approval by the institutional review board (IRB).

Criteria
Inclusion Criteria:

- Male or female patients agedā‰„18 years

- Idiopathic recurrent pericarditis with at least 2 recurrences

- Recurrent pericarditis defined as a first episode of acute pericarditis followed by
recurrences (at least two recurrences for this study). First episode of pericarditis
is diagnosed when at least two of the following criteria were present: pericarditis
typical chest pain (sharp and pleuritic, improved by sitting up and leaning forward),
pericardial friction rubs, widespread ST segment elevation or PR interval (PR)
depressions not previously reported, and new or worsening pericardial effusion.
Recurrence is diagnosed when chest pain recurs and one or more of the following signs
is present: fever, pericardial friction rub, ECG changes, echocardiographic evidence
of new or worsening pericardial effusion, and elevations in the white blood cell
count, erythrocyte sedimentation rate or C-reactive protein. To be enrolled in this
study, elevation of C-reactive protein is mandatory both in the first attack and in
the following recurrences. The investigators differentiate recurrences from incessant
pericarditis, term used to define patients with continued activity of pericarditis
(with a symptom-free interval of < 6 weeks)

- Specific aetiologies excluded, including tuberculous, neoplastic or purulent
aetiologies, post-cardiac injury syndromes, and rheumatic autoimmune diseases.

- Female subjects must be postmenopausal, or incapable of pregnancy or permanently
sterile, or if of childbearing potential must agree to use highly-effective method of
contraception.

- Signed written informed consent by the patient for participation in the study and
agreement to comply with the medication and the follow-up schedule.

Exclusion Criteria:

- Ophthalmologic contraindications

- Structural heart disease

- Corrected QT interval >440msec in men and >450msec in women

- Left ventricular hypertrophy >13mm in men and >11mm in woman

- Known allergy or intolerance to hydroxychloroquine

- Life expectancy of < 12 months

- Complex congenital heart disease

- History of ventricular arrhythmias other than isolated extrasystoles

- Women who are pregnant (as evidenced by pregnancy test if pre-menopausal)

- Known channelopathy such as Brugada syndrome, long QT syndrome, or Catecholaminergic
monomorphic ventricular tachycardia

- On the heart transplant list
