Abstract
Malaria remains one of the most prevalent infectious diseases globally. Despite targets set out by the WHO in 2015, there has been a rise in the number of cases since 2019 as an indirect effect of the COVID-19 pandemic.Cardiac complications are very rarely witnessed with severe malaria. Of the cardiac sequelae, myocarditis is one of the most frequently observed with a handful of case reports in the literature. We report a case of a man in his 50s who developed myocarditis while being managed for severe Plasmodium falciparum malaria in an intensive care unit in the UK and review the literature relevant to this case. This is the second reported case of this condition in the UK.

Abstract
A large number of sudden and unexpected deaths are caused by infections. Bacterial and viral infections remain the most common causes of sudden death from infectious diseases. Sudden deaths resulting from infectious causes involving the cardiovascular system are commonly reported due to myocarditis and infective endocarditis while sudden deaths involving the respiratory system are mostly due to pneumonia and tuberculosis. Detailed medicolegal investigation is warranted in sudden deaths due to infectious diseases involving a thorough autopsy and histopathological evaluation along with the use of microbiology and molecular diagnostic methods.

Idiopathic acute myocarditis during treatment for controlled human malaria infection: a case report. Malar J 2014; 13:38. [PMID: 24479524 PMCID: PMC3909449 DOI: 10.1186/1475-2875-13-38] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2013] [Accepted: 01/27/2014] [Indexed: 11/10/2022] Open
Abstract
A 23-year-old healthy male volunteer took part in a clinical trial in which the volunteer took chloroquine chemoprophylaxis and received three intradermal doses at four-week intervals of aseptic, purified Plasmodium falciparum sporozoites to induce protective immunity against malaria. Fifty-nine days after the last administration of sporozoites and 32 days after the last dose of chloroquine the volunteer underwent controlled human malaria infection (CHMI) by the bites of five P. falciparum-infected mosquitoes. Eleven days post-CHMI a thick blood smear was positive (6 P. falciparum/μL blood) and treatment was initiated with atovaquone/proguanil (Malarone®). On the second day of treatment, day 12 post-CHMI, troponin T, a marker for cardiac tissue damage, began to rise above normal, and reached a maximum of 1,115 ng/L (upper range of normal = 14 ng/L) on day 16 post-CHMI. The volunteer had one ~20 minute episode of retrosternal chest pain and heavy feeling in his left arm on day 14 post-CHMI. ECG at the time revealed minor repolarization disturbances, and cardiac MRI demonstrated focal areas of subepicardial and midwall delayed enhancement of the left ventricle with some oedema and hypokinesia. A diagnosis of myocarditis was made. Troponin T levels were normal within 16 days and the volunteer recovered without clinical sequelae. Follow-up cardiac MRI at almost five months showed normal function of both ventricles and disappearance of oedema. Delayed enhancement of subepicardial and midwall regions decreased, but was still present. With the exception of a throat swab that was positive for rhinovirus on day 14 post-CHMI, no other tests for potential aetiologies of the myocarditis were positive. A number of possible aetiological factors may explain or have contributed to this case of myocarditis including, i) P. falciparum infection, ii) rhinovirus infection, iii) unidentified pathogens, iv) hyper-immunization (the volunteer received six travel vaccines between the last immunization and the CHMI), v) atovaquone/proguanil treatment, or vi) a combination of these factors. Definitive aetiology and pathophysiological mechanism for the myocarditis have not been established.

Abstract
Malaria inflicts a huge health care burden in terms of mortality and morbidity worldwide. There has been evidence in the literature where many unexpected/unexplained deaths turned out to be related to malaria on autopsy. The aim of this study is to review autopsy diagnosed malaria related deaths in the literature with due stress to its biologic and forensic aspects. A meticulous literature search was performed for "sudden malaria death", "malaria death postmortem diagnosis" and "unexplained death malaria" across PubMed, SCOPUS, Cochrane Database of Systematic Reviews, Allied and Complementary Medicine, British Nursing Index, CINAHL, EMBASE, Ovid-MEDLINE and Google Scholar. All the literature was thoroughly reviewed and analyzed with reference to the type of study, location, travel history, age, gender, circumstance of death, method of diagnosis, species involved, chemoprophylaxis usage and take home message from the particular study. Plasmodium falciparum was responsible in most of the cases. The symptoms mimicked influenza in most of the case reports. Travel to endemic areas was common to most of the victims. The travelers were from all over the world including USA, France, Switzerland, Spain, Portugal, Germany and Asia (China and Japan). Vascular congestion with the presence of malarial pigment laden RBCs in capillaries of various organs was the major histopathology finding. Such lesions were found in the brains of all subjects (100%), liver of 78% of the cases, spleen in 67%, lungs in 56% and myocardium in 43% of the cases. Peripheral smear and rapid diagnostic test was of great aid to the autopsy in many cases. PCR was used for diagnosis as well as exclusion of possibility of co-infection with other species in case of Plasmodium knowlesi related death. The postmortem and histopathology findings in this case were similar to P. falciparum except for the fact that brain sections were negative for intracellular adhesion molecule-1. Chemoprophylaxis was not taken by the victims except for two in whom history of chloroquine based chemoprophylaxis was mentioned. Given the worldwide prevalence of the disease, increasing international travel and rapidly developing drug resistance, malaria will continue to be an important disease and should be considered in all cases of unexpected deaths particularly in malaria endemic regions or in presence of travel history to endemic regions.

Abstract
We describe a fatal case of imported malaria where the sole finding revealed at the postmortem evaluation was an acute lymphocytic myocarditis with myocardiolysis. This case recalls the potential importance of myocardial injury in the prognosis of malaria and prompts a reevaluation of current perspectives on the pathogenesis of severe falciparum infection. In the light of this, we have reviewed the cases of cardiac complications in malaria published to date.

Abstract
We report on the case of a French citizen who was found dead in his home, 4 days after returning from Cameroon. The patient died of imported malaria, as revealed by the postmortem investigations. Few such cases have been reported throughout the world. This article reviews deaths due to malaria diagnosed at the time of autopsy in France between 1995 and 2005. We conclude that the nonspecific symptoms of malaria can lead to a misdiagnosis and the need for a forensic expert to intervene at the scene of death, which usually occurs in the home. We will remind forensic pathologists of the clinical, biologic, and forensic aspects of this infectious disease. In particular, the uses of microbiologic analyses, the QBC malaria test and the Core malaria Pan/Pv/pf test as well as brain tissue histology will be reviewed.

Abstract
A 20 year-old healthy female volunteer participated in a clinical Phase I and IIa safety and efficacy trial with candidate malaria vaccine PfLSA-3-rec adjuvanted with aluminium hydroxide. Eleven weeks after the third and last immunization she was experimentally infected by bites of Plasmodium falciparum-infected mosquitoes. When the thick blood smear became positive, at day 11, she was treated with artemether/lumefantrine according to protocol. On day 16 post-infection i.e. two days after completion of treatment, she woke up with retrosternal chest pain. She was diagnosed as acute coronary syndrome and treated accordingly. She recovered quickly and her follow-up was uneventful. Whether the event was related to the study procedures such as the preceding vaccinations, malaria infection or antimalarial drugs remains elusive. However, the relation in time with the experimental malaria infection and apparent absence of an underlying condition makes the infection the most probable trigger. This is in striking contrast, however, with the millions of malaria cases each year and the fact that such complication has never been reported in the literature. The rare occurrence of cardiac events with any of the preceding study procedures may even support a coincidental finding. Apart from acute coronary syndrome, myocarditis can be considered as a final diagnosis, but the true nature and patho-physiological explanation of the event remain unclear.

Abstract
Malaria is a major cause of morbidity and mortality with an annual death toll exceeding one million. Severe malaria is a complex multisystem disorder, including one or more of the following complications: cerebral malaria, anemia, acidosis, jaundice, respiratory distress, renal insufficiency, coagulation anomalies, and hyperparasitemia. Using a combined in vivo/in vitro metabolic-based approach, we investigated the putative pathogenic effects of Plasmodium berghei ANKA on brain, in a mouse strain developing malaria but resistant to cerebral malaria. The purpose was to determine whether the infection could cause a brain dysfunction distinct from the classic cerebral syndrome. Mice resistant to cerebral malaria were infected with P. berghei ANKA and explored during both the symptomless and the severe stage of the disease by using in vivo brain magnetic resonance imaging and spectroscopy. The infected mice did not present the lesional and metabolic hallmarks of cerebral malaria. However, brain dysfunction caused by anemia, parasite burden, and hepatic damage was evidenced. We report an increase in cerebral blood flow, a process allowing temporary maintenance of oxygen supply to brain despite anemia. Besides, we document metabolic anomalies affecting choline-derived compounds, myo-inositol, glutamine, glycine, and alanine. The choline decrease appears related to parasite proliferation. Glutamine, myo-inositol, glycine, and alanine variations together indicate a hepatic encephalopathy, a finding in agreement with the liver damage detected in mice, which is also a feature of the human disease. These results reveal the vulnerability of brain to malaria infection at the severe stage of the disease even in the absence of cerebral malaria.

Abstract
Background The importance of vascular occlusion in the pathogenesis of human haemoprotozoal disease is unresolved. Methods Giemsa-stained tissue sections from a human case of Babesia microti infection in a splenectomized patient with chronic lymphocytic leukaemia and colon cancer were examined to ascertain the distribution of parasitized erythrocytes within the vascular lumen. Results No evidence of sequestration was observed. Conclusion This first report on the vascular location of B. microti in human tissue suggests that severe multi-organ failure due to babesiosis is independent of sequestration of parasitized erythrocytes. A similar pathogenesis may also cause multi-organ failure in other intraerythrocytic protozoal infections, including falciparum malaria.
