Fungal pericarditis is a rare disease but its incidence has risen in parallel with the global increase in invasive fungal infections. This systematic review analyzes data from previously reported cases of fungal pericarditis to provide an improved understanding of the etiology, clinical presentation, management, and outcomes of this rare disease. We reviewed Medline and Scopus databases from 1 January 1990 to 29 January 2024 for case reports that documented the isolation of a fungal pathogen from pericardial fluid or tissue. Of the 2330 articles screened, 101 cases met the inclusion criteria. Patients with fungal pericarditis and the involvement of at least one other organ—usually the lungs, brain, or kidney—had worse outcomes than patients with isolated pericardial disease. Immunosuppression was reported in 50% of cases and was associated with worse outcomes in adults. Patients who presented with chest pain, received adequate empiric antifungal therapy, and underwent pericardiocentesis and pericardiectomy had improved survival. The most common isolated pathogens were Candida spp., followed by Aspergillus spp. and Mucor spp., with the latter two linked to worse outcomes. Only 35% of patients received empiric antifungal medications before the causative pathogen was identified, and mortality was associated with a delay in appropriate therapy. Immunosuppression, disseminated disease, and presence of shock/multiorgan failure were additional risk factors associated with death. Fungal pericarditis carries a mortality rate of up to 50%, with nearly half of patients being immunocompromised. Clinicians frequently do not consider fungal pericarditis in the differential diagnoses, which leads to delays in treatment and poorer outcomes. Further prospective multicenter studies are urgently needed to better understand the epidemiology, improve diagnostic testing and management, and decrease unacceptably high mortality in patients with fungal pericarditis.

Background: Immune checkpoint inhibitors (ICIs) have been successfully used in the previous decade for the treatment of a variety of malignancies. Adverse events (AEs) can cause many symptoms, most notably cardiac. We analyzed the frequency of these adverse events, comparing pembrolizumab and other ICIs. Methods: Using the Food and Drug Administration (FDA) adverse event reporting database (FAERS), we searched for all adverse events of interest reported for every ICI included in this study. After obtaining the data, we conducted a disproportionality analysis using the reporting odds ratio (ROR) and the information component (IC). Results: A total of 6719 ICI-related cardiac adverse events of interest were reported in the database. Serious outcomes were reported in 100% of the cases, with 34.3% of the cases ending fatally. Compared with all other medications in the database, pembrolizumab use was more frequently associated with myocarditis, pericardial disease, heart failure, and atrial fibrillation. No difference was found in cardiotoxicity between different ICIs. Conclusions: Although infrequent, cardiac AEs in pembrolizumab use are associated with serious outcomes and high mortality. Prospective studies are needed to further research the connection between ICI use and cardiotoxicity.

(1) Background: Cardiomyopathy in celiac disease or celiac cardiomyopathy (CCM) is a serious and potentially life-threatening disease that can occur in both adults and children. However, data supporting the causal relationship between celiac disease (CD) and cardiomyopathy (CMP) are still inconsistent. The aim of this study was to review and synthesize data from the literature on this topic and potentially reveal a more evidence-based causal relationship. (2) Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to search Medline, Embase, and Scopus databases from database inception until September 2023. A total of 1187 original articles were identified. (3) Results: We identified 28 CCM patients (19 adult and 9 pediatric) with a mean age of 27.4 ± 18.01 years. Adult patients with CCM were predominantly male (84.2%) while pediatric patients were predominantly female (75%). The most common comorbidities associated with CCM were anemia (75%) and pulmonary hemosiderosis (20%). In 35% of patients, CCM occurred before the diagnosis of CD, while in 48% of patients, CCM and CD were diagnosed at the same time. Diagnosis of CD preceded diagnosis of CCM in only 18% of patients. Diagnosis of CCM is often delayed with an average, from the onset of symptoms to diagnosis, of 16 months. All patients were treated with a gluten-free diet in addition to guideline-directed medical therapy. At 11-month follow-up, cardiovascular improvement was seen in 60.7% of patients. Pediatric mortality was 33.3%, while adult mortality was 5.3%. (4) Conclusions: Clinicians should be aware of the possible association between CD and CMP, and we recommend CD work-up in all patients with CMP who have concomitant anemia. While we identified only 28 cases in the literature, many cases might go unreported due to a lack of awareness regarding CCM. A high degree of clinical suspicion and a prompt diagnosis of CCM are essential to minimizing the risks of morbidity and mortality, as the combination of a gluten-free diet and guideline-directed medical therapy can improve clinical outcomes.

Myopericarditis is a rare complication of influenza infection. The presentation may range from mild and frequently unrecognized, to fulminant and potentially complicated by cardiogenic and/or obstructive shock (tamponade), which is associated with high mortality. We performed a review of literature on all influenza pericarditis and myopericarditis cases according to PRISMA guidelines using the PubMed search engine of the Medline database. Seventy-five cases of influenza myopericarditis and isolated pericarditis were identified from 1951 to 2021. Influenza A was reported twice as often as influenza B; however, influenza type did not correlate with outcome. Men and elderly patients were more likely to have isolated pericarditis, while women and younger patients were more likely to have myopericarditis. All included patients had pericardial effusion, while 36% had tamponade. Tamponade was more common in those with isolated pericarditis (41.2%) than myopericarditis (13.8%). Cardiogenic shock was more common in patients with myopericarditis (64%), with an overall mortality rate of 14.7%. Nearly 88% of the recovered patients remained without long-term complications reported. Conclusion: Influenza A appears a more common cause of pericarditis and myopericarditis. Isolated pericarditis was more commonly associated with tamponade but without reported deaths, whereas myopericarditis was more commonly associated with cardiogenic shock and death (19%).

In the expanding era of antibiotic resistance, new strains of Staphylococcus aureus have emerged which possess resistance to traditionally used antibiotics (MRSA). Our review aimed to systematically synthesize information on previously described MRSA pericarditis cases. The only criterion for inclusion was the isolation of MRSA from the pericardial space. Our review included 30 adult and 9 pediatric patients (aged: 7 months to 78 years). Comorbid conditions were seen in most adult patients, whereas no comorbidities were noted amongst the pediatric patients. Pericardial effusion was found in 94.9% of cases, with evidence of tamponade in 83.8%. All cases isolated MRSA from pericardial fluid and 25 cases (64.1%) had positive blood cultures for MRSA. Pericardiocentesis and antibiotics were used in all patients. The mortality rate amongst adults was 20.5%, with a mean survival of 21.8 days, and attributed to multi-organ failure associated with septic shock. No mortality was observed in the pediatric population. In adult patients, there was no statistical difference in symptom duration, antibiotic duration, presence of tamponade, age, and sex in relation to survival. Conclusion: MRSA pericarditis often presents with sepsis and is associated with significant mortality. As such, a high clinical suspicion is needed to proceed with proper tests such as echocardiography and pericardiocentesis. In more than one third of the cases, MRSA pericarditis occurs even in the absence of documented bacteremia.

Cardiac involvement in drug reaction with eosinophilia and systemic symptoms (DS) is rare but associated with high mortality. The aim of this research was to systematically review case reports by PRISMA guidelines in order to synthetize the knowledge of cardiac manifestations of DS. We identified 42 cases from 36 case reports. Women were two times more affected than men. Two-thirds of patients had cardiac manifestation in the initial phase of the disease, while in one-third of cases cardiac manifestations developed later (mean time of 70 ± 63 days). The most common inciting medications were minocycline (19%) and allopurinol (12%). In 17% of patients, the heart was the only internal organ affected, while the majority (83%) had at least one additional organ involved, most commonly the liver and the kidneys. Dyspnea (55%), cardiogenic shock (43%), chest pain (38%), and tachycardia (33%) were the most common cardiac signs and symptoms reported. Patients frequently had an abnormal ECG (71.4%), and a decrease in left ventricular ejection fraction was the most common echocardiographic finding (45%). Endomyocardial biopsy or histological examination at autopsy was performed in 52.4%, with the predominant finding being fulminant eosinophilic myocarditis with acute necrosis in 70% of those biopsied. All patients received immunosuppressive therapy with intravenous steroids, while non-responders were more likely to have received IVIG, cyclosporine, mycophenolate, and other steroid-sparing agents (60%). Gender and degree of left ventricular systolic dysfunction were not associated with outcomes, but short latency between drug exposure and the first DRESS symptom onset (<15 days) and older age (above 65 years) was associated with death. This underscores the potential importance of heightened awareness and early treatment.
