Fatal cytomegalovirus myocarditis in a seronegative ALL patient

Infections in Leukemia and Hematopoietic Stem Cell Transplantation

Infections are one of the most common complications in patients diagnosed with leukemia and serve as a major obstacle to treatment. Through the early 1970s, infections were the most common cause of death in patients diagnosed with acute leukemia, but improvement in treatment and supportive care over the past few decades, coupled with expanded prophylaxis and prevention regimens, have led to reduction in both the frequency and severity of infections. Regardless, due in part to an aging cancer population and the diversity of cancer treatments and procedures, infectious diseases remain a major cause of morbidity and mortality in patients with leukemia.

Rapidly fatal acute bacterial myocarditis in a nonneutropenic child with acute lymphoblastic leukemia in remission

The authors report a fatal case of acute bacterial myocarditis in a nonneutropenic child with acute lymphoblastic leukemia. She was admitted to the hospital with a urinary tract infection resulting from and remained persistently febrile despite resolution of the infection. On hospital day 4 signs of acute cardiac failure developed. Despite aggressive resuscitation measures, she died. Pathologic examination revealed the cause of death to be bacterial myocarditis. In addition, she was found to have a generalized decrease in her serum immunoglobulin levels. Acute bacterial myocarditis in patients with malignancy has been rarely reported. The rapid clinical deterioration and death in the patient in this report is particularly interesting.

Cytomegalovirus myocarditis in a healthy infant: Complete recovery after ganciclovir treatment

OBJECTIVES: To report a case of acute myocarditis caused by cytomegalovirus infection in a 15-month-old immunocompetent infant completely recovered with ganciclovir treatment. DESIGN: Descriptive case report. SETTING: Pediatric intensive care unit in a general hospital. Patient: A 15-month-old healthy girl with acute, severe myocarditis. INTERVENTION: General supportive intensive care and mechanical ventilatory support, iv immunoglobulin, and iv ganciclovir. MEASUREMENTS AND MAIN RESULTS: Intensive supportive care including iv fluids, mechanical ventilatory support, diuretics (furosemide, spironolactone), digoxin, dobutamine, captopril, methylprednisolone, and iv immunoglobulin. Despite clinical stabilization, shortening fraction remained very poor at 17%. Addition of iv ganciclovir resulted in prompt and complete recovery of the cardiac muscle contractility with a shortening fraction of 35% that remained normal during a long follow-up period. CONCLUSIONS: Cytomegalovirus should be considered as a causative agent in acute myocarditis even in the normal, immunocompetent host. In such cases, addition of ganciclovir treatment should be strongly considered.
