We aimed to characterize the epidemiology, diagnostic peculiarities and outcome determinants of bacterial myocarditis. Two cases from our institution and literature reports were collected ending up with a total of 66 cases. In 37 (56%) patients, the diagnosis was confirmed by magnetic resonance and histopathological criteria. The other patients were classified as having possible myocarditis. Only occurrence of rhythm disturbances was associated with the specific diagnosis of myocarditis (p = 0.04). Thirty-two (48%) patients presented with severe sepsis that was associated with a worse prognosis. At multivariate analysis, left ventricular ejection fraction (LVEF) at admission and heart rhythm disturbances were associated with incomplete recovery (odds ratio (OR) 1.1, 95% (CI) 1.03–1.2, p = 0.004 and OR 6.6, 95% CI 1.35–32.5, p = 0.02, respectively). In summary, bacterial myocarditis is uncommon. Most commonly, it is secondary to septic dissemination of bacteria or to transient secondary myocardial toxicity.

“…Myocarditis has been observed as an autopsy finding in fatal cases of Rocky Mountain spotted fever. Other much rarer forms of tick borne rickettsial infections like Sibirica mongolitimonae infections are also known to cause clinically significant myopericarditis [8]. R. conorii related cardiac involvement is extremely rare and only about 6 cases are described in the literature [9].…”

“…However, in acutely ill patients it is not justifiable do biopsy as it does not alter the management. Further, in the available literature suggests that rickettsial infections related cardiac dysfunction is more likely to be due to myocarditis [8, 9, 12]. Newer methods including cardiac MRI and segmented inversion recovery gradient-echocardiography pulse sequences have a better sensitivity in diagnosing acute myocarditis [13, 14].…”

Spotted fever rickettsioses causing myocarditis and ARDS: a case from Sri Lanka

et al. 2018

View full text Add to dashboard Cite

BackgroundSpotted fever group of rickettsial infections are emerging in Sri Lanka. We describe a patient with rapidly progressing ARDS and myocarditis secondary to spotted fever caused by Rickettsia conorii. ARDS and myocarditis are rare complications of Rickettsia conorii infections and only a few cases are reported to date.Case presentationA 53 years old manual worker presented with fever for 5 days and a skin rash. He was in circulatory failure on admission and developed severe hypoxaemia with gross changes in chest radiograph by next day requiring assisted ventilation. He had myocarditis causing left ventricular failure and acute respiratory distress syndrome. He was confirmed to have spotted fever rickettsial infection with rising titre of indirect immunofluorescence antibodies to Ricketssia conorii and made a complete recovery with appropriate antibiotic therapy and supportive care.ConclusionRickettsial infections can present with diverse manifestations. Even the patients with severe organ involvements such as myocarditis and ARDS can be completely cured if timely identified and treated.

“…In Europe, vectors include the tick species Hyalomma excavatum, H. marginatum, H. turanicum, Rhipicephalus pusillus, R. bursa, and Haemaphysalis parva (1,2,4). R. sibirica mongolitimonae infection usually causes mild disease, but severe manifestations have been described, including retinal vasculitis, lethargy with hyponatremia, septic shock, myopericarditis, and acute renal failure (2,6).…”
