[CIS PIDD] [cis-pidd] patient with Bruton and refractory pericarditis

[Laia Alsina Manrique de Lara]

Dear all,

I contact you regarding an 8-yo boy diagnosed with Bruton disease at 20 months of age in the context of a reactive arthitis of the knee. Since then, on IG substitution (though levels >10 gr) with no main infections nor other complications. He is well grown.

He was diagnosed 1.5 months ago with a pericarditis of undefined origin after extensive studies (see biochemical and microbiological studies below) that was finally treated with steroids.

The diagnosis of pericarditis was performed based on clinical symptoms (central chest pain) along with EKG and ecography with 20mm of pericardial liquid. He had significant inflammatory signs (fever 38,5ºC, leucocitosis and elevated CRP and ESR). He was empirically treated with antibiotics (cefotaxime + vancomycin after pericardiocentesis)

After reducing the dose of steroids due to initial good response to treatment, the pericarditis has rapidly reproduced.

Has anybody experience with this  complication ocurring in Bruton disease?
--is the pericarditis viral and I am not controlling a virus I haven't found? Should I give more IGIV for this purpose?
--can Bruton patients have reactive/inflammatory pericarditis?








Pericardial liquid (22/01/2013): serohematic. Proteines 75 g/L, Glucose 52 mg/dl (blood 92 mg/dl). Leucocites 3.150/mm3 (Mononuclear 50%, PMN 50%). ADA 101.9 UI/L.

PCR enterovirus, rinovirus, coronavirus, influenza, parainfluenza, adenovirus, bocavirus: negative.

Ziehl Neelsen in pericardial liquid: negative. ELISPOT BK: negative. PPD + chest X-ray patient and parents is negative.

Culture: negative.




Thank you in advance,

Laia
