Thirty-six chronic renal failure patients who had findings compatible to pericarditis such as pericardial friction rub, chest pain, high fever or who had pericardial effusion on echocardiography which was performed due to cardiomegaly were
divided
into
uremic pericarditis and dialysis associated pericarditis according to the duration of dialysis. Pericarditis developed before the dialysis or less than 8 weeks of dialysis was defined as uremic pericarditis and pericarditis developed after than 8
weeks
of dialysis was defined as dialysis associated pericarditis. We evaluated sex, age, incidence of diabetes mellitus, dialysis duration, blood pressure, blood chemistry, pericardial effusion amount, the incidence of cardiac tamponade, treatment
modality
in both type of pericarditis.
1) Among 36 patients uremic pericarditis were 21 (58.3%) cases and dialysis associated pericardits 15 (41.7%) cases. Cardiac tamponade were founded in 2(9.5%) and 3(20%) cases each.
2) The sex ratio in uremic and dialysis associated pericarditis were 17:4 and 10:5, the mean age 42.9 and 46.9 years. Diabetes mellitus were in 4(19.1%) and 5(33.3%) cases and the mean dialysis duration until the pericarditis revealed were 27.0
and
710.3 days each.
3) BUN, creatinine, total protein, albumin, hemoglobin, hematocrit level didn't show any statistical differences between the uremic and dialysis associated pericarditis.
4) The echocardiographic findings of the uremic pericarditis at the time of the diagnosis revealed small amount 9 (42.9%), moderate 8(38.1%), large 4(19.0%) cases each. The findings of dialysis associated pericarditis were small amount 7(46.7%),
moderate 6(40.0%), large 2(13.3%) cases which showed no statistical differences with the amount of pericardial effusion of uremic pericarditis.
5) the treatment of uremic pericarditis were medical 18(85.7%) cases and surgical 3(14.3%) cases and the dialysis associated pericarditis were 11(73.3%) and 4(26.7%) case each.
In conclusion, the dialysis associated pericarditis which developed more cardiac tamponade and needed more surgical treatment than the uremic pericarditis seems to have poor prognosis than the uremic pericarditis, but for better analysis of
prognosis
and pathogenesis prospective study with large group of patients are required.
