High Serum Ferritin in Adult-Onset Still's Disease

International Journal of Clinical Medicine 2010年第2期1卷 81-83页

作者： Peter Jandus Wei Wang michael seitz Felix Wermelinger Hans-Peter Kohler 不详

In August 2009, a 28-year-old Spanish woman was referred in reduced general condition after at least four medical consultations with a 2 week history of remittent fever, night sweats, exanthema and intermittent arthralgias. Noticeable in the clinical examination was only an urticarial rash on the trunk and extremities and body temperature of 39.6°C. Laboratory tests: WBC with a slight left shift (32%), mild thrombocytopenia (128 G/l), CRP 78 mg/l (N: < 5), elevated transaminases [ASAT 67 U/l (N: 10-37), ALAT 45 U/l (N: 30-65)]. On the fifth day maximum values for ASAT 322 U/l and ALAT 378 U/l were reached. During hospitalisation recurrent fever up to 39.0°C has been documented associated with arthralgias and myalgias. An infection with blood cultures and serology tests was excluded. Rheumatology analysis, urine analysis, chest X-ray, and abdominal ultrasound were inconspicuous. A serum ferritin level of 5493 μg/l (N: 23-110) was detected with peak four days later (8530 μg/l). AOSD was suspected and prednisolone (1 mg/kg body weight) started. The patients recovered rapidly. Transaminases (ASAT 47 U/l, ALAT 149 U/l), CRP (34 mg/l), and ferritin level (1969 μg/l) regressed within 3 days. 3 months later, prednisolone was discontinued;she presented fever (40°C), myalgias, macular rash on the trunk, sore throat and oligoarthritis. Laboratory tests including WBC were without pathologic findings except for transaminases (ASAT 83 U/l, ALAT 53 U/l), CRP (370 mg/l) and ferritin (7434 μg/l). An infectious process was excluded. After resumption of prednisolone 10 mg daily, quick relief of symptoms occurred. Given the short time of relapse, immunosuppressive therapy with cyclosporin was initiated (4 mg/kg body weight). Since that time the patient remained symptom free for over 8 months.

Good Outcome after More Than a Million Troponin in Serum

引用

Case Reports in Clinical Medicine 2022年第1期11卷 25-30页

作者： Mohamed Elbayomi Timo seitz michael Weyand Department of Cardiac Surgery Friedrich-Alexander-University Erlangen-Nuremberg Erlangen Germany

A troponin in serum of more than one Million in vivo is rare insult. We report a case of 85-year-old woman who was transferred to our institution because of acute ST elevated myocardial infarction and the troponin level reached a peak of 1,032,904.2 pg/ml. She was discharged with highly reduced left ventricular function, however in the three months follow up after a coronary bypass operation she completely was free from heart failure symptoms and echocardiography showed a totally normal function of both ventricles. This case study highlights that the initial serum troponin in acute settings can mislead the long-term prognosis and gives prominence to the expeditious myocardial revascularization.
