[PMID: 38792816 PMCID: PMC11123953 DOI: 10.3390/microorganisms12050987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2024] [Revised: 05/06/2024] [Accepted: 05/09/2024] [Indexed: 05/26/2024] Open
Abstract
BACKGROUND Infective endocarditis (IE) continues to be a disease with high mortality despite medical advances. OBJECTIVE The objective of this study was to investigate the characteristics and prognosis of IE according to the affected valves. MATERIALS AND METHODS This study was retrospective and single-centered, and it included 270 patients with a diagnosis of IE, for the period 2005-2021, who received treatment at the University Hospital "St. Georgi" in Plovdiv, Bulgaria. RESULTS Single-valve IE (SIE) was found in 82.6% (n-223), multivalvular IE (MIE) in 16.66% (n = 45) and device IE (CDRIE) in 0.74% (n = 2) of patients. The most commonly affected valve was the aortic valve, in 44.8% (n = 121). The predominant multivalvular involvement was aortic-mitral valves (AV-MV) (13.7%, n = 37). The patients with tricuspid valve (TV) IE were significantly younger, at 39 (30) years, and were more frequently male (80.8%). Mortality was higher in MIE than in SIE (31.1% vs. 23.8%) and was the highest in multivalve aortic-tricuspid (AV-TV) IE (75%). Early surgery was performed most in AV-MV IE, in 29.7% (n = 11). The Charlson comorbidity index (CCI) was significantly higher in MV 4 (4) and AV 3 (3) vs. TV IE 1 (5) (p = 0.048 and p = 0.011, respectively). Septic shock occurred most frequently in AV-TV involvement (75%; p = 0.0001). The most common causative agents were of the Staphylococcus group. Staphylococcus aureus more often affected TV alone (46.2%, n = 124) vs. AV (9.9%, n = 14; p = 0.0001) and vs. MV (22.6%, n = 17; p = 0.022); Staphylococcus coagulase-negative (CNG) was the prevalent cause of MV IE (22.7%, n = 17) vs. AV-MV (2.7%, n = 1; p = 0.007). Streptococci were represented in a low percentage and only in left-sided IE, more frequently in AV-MV (18.9%, n = 7) vs. AV (6.6%, n = 8; p = 0.025). CONCLUSIONS The aortic valve is the most frequently affected valve, as single-valve IE or as multivalve AV-MV, with the predominant causative agents being of the Staphylococcus group. AV-TV IE has the worst prognosis, with the most common complication of septic shock and the highest in-hospital mortality.

Abstract
BACKGROUND Infective endocarditis (IE) is a relatively rare but serious and life-threatening disease with substantial mortality and morbidity despite progress in diagnostic and treatment techniques. The aim of this study is to investigate the epidemiology, clinical characteristics, microbiological profile, and outcomes of IE patients in a tertiary care facility in Jordan, the Jordan University Hospital (JUH). METHODS This is a retrospective case series study which was conducted at JUH. A total of 23 patients with either definite or possible IE according to the Modified Duke Criteria were included in the study. Medical records were reviewed, and relevant information was collected. Descriptive data analysis was performed. RESULTS Our study identified a total of 23 patients with infective endocarditis; 65.2% were males, with a mean age of 40.4 years. The majority of patients had an underlying cardiac disease (60.9%), with the most common being congenital heart diseases (17.4%). The most commonly affected valves were the left-side heart valves, with the mitral valve (52.2%) being the most common followed by the aortic valve (34.8%). The most common organism detected in blood culture was Streptococcus viridans (21.7%) followed by methicillin-resistant Staphylococcus aureus. The most common complications among the patients were heart failure and septic shock, and the mortality rate among the patients was 13%. CONCLUSION In patients with endocarditis, Streptococcus viridans is the most common culture-positive bacteria at JUH. One third of our patients needed surgical intervention and the mortality rate was 13%.

Abstract
Bartonellosis is a vector-borne and zoonotic diseases in humans, especially in immunocompromised individuals. However, there is no complete data about the geographical distribution of different species of Bartonella, as well as the status of its reservoirs, vectors, and human cases in most parts of the world. In this study, published reports related to Bartonella species from WHO-EMRO region countries were searched in different databases until October 2023. The eighteens different species of Bartonella were reported in WHO-EMRO countries including Bartonella henselae, Bartonella quintana, Bartonella elizabethae, Bartonella bovis, Bartonella clarridgeiae, Bartonella vinsonii, Bartonella doshiae, Bartonella taylorii, Bartonella rochalimae, Bartonella tribocorum, Bartonella rattimassiliensis, candidatus Bartonella merieuxii, candidatus Bartonella dromedarii, Bartonella acomydis, Bartonella jaculi, Bartonella coopersplainsensis and Bartonella koehlerae. Also, only human cases of B. henselae and B. quintana infections were reported from WHO-EMRO countries. The infections of Bartonella are important in the WHO-EMRO region, but they have been neglected by clinicians and healthcare systems.

Abstract
Key clinical massage A 23-year-old rancher was admitted with the diagnosis of brucellosis. In evaluations, a massive vegetation in the aortic valve was seen. A combination of antibiotic therapy and cardiac surgery were performed, it seems this approach reduces mortality and complications. Abstract Brucellosis (also known as "undulant fever," "Mediterranean fever," or "Malta fever") is a zoonotic infection transmitted to humans from infected animals (cattle, sheep, goats, camels, pigs, or other animals) by ingestion of food products (such as unpasteurized dairy products) or by contact with tissue or fluids. It is the most frequent zoonosis globally and a major public health issue in many resource-poor nations. Endocarditis is one of the rarest and most dangerous consequences of brucellosis. Additionally, the combination of endocarditis with cardiomyopathy increases its rarity. This condition is usually treated with a high level of suspicion Serological, clinical, and epidemiological data can all be used to make a diagnosis. The use of echocardiography aids in the early diagnosis. Due to the high risk of recurrence and the extent of tissue destruction brought on by Brucella, the majority of experts advise an early surgical intervention; nevertheless, other writers assert that low-risk patients also require cautious therapy. In this article, we discuss the situation of a patient who underwent surgery and had Brucella endocarditis and heart failure. In conclusion, a combination of antibiotic therapy and cardiac surgery, reduces mortality and complications associated with Brucella endocarditis and improves patient quality of life.

Abstract
A male adult patient on maintenance haemodialysis due to end-stage diabetic nephropathy presented with low-grade intermittent fever, cough and generalised weakness for 3 weeks. Initial blood investigations revealed an elevated neutrophil count with raised inflammatory markers. Chest CT revealed loculated hydropneumothorax with multiple cavitary nodules. Repeated blood cultures from the cuffed tunnelled catheter site and the right arm and sputum cultures were negative for pyogenic bacteria and yeast aetiology. The patient complained about left axillary pain on the fourth day of admission. Ultrasound-guided percutaneous aspiration from an axillary focal collection and subsequent culture revealed a methicillin-resistant Staphylococcus aureus (MRSA) infection. Echocardiography detected multiple vegetations on the tricuspid valve. The patient responded clinically to vancomycin and removal of the permanent catheter. This was a case of a tunnelled catheter-related metastatic MRSA infection with infective endocarditis, pulmonary septic embolism with a subacute presentation, and repeated blood culture negativity.

Abstract
Infective endocarditis (IE) is a serious and potentially life-threatening infection of the heart valves. It is commonly treated with prolonged courses of intravenous antibiotics, and in some cases, surgical intervention may also be necessary. While the use of oral antibiotics in the treatment of IE is generally limited, there are select cases where they may be considered as an alternative treatment option. Here, we report a case of staphylococcal right-sided IE successfully treated with oral antibiotics (linezolid and rifampicin). Our case highlights the potential for oral antibiotics to be used as step-down therapy for select patients with IE.

Abstract
Lysins are bacteriophage-derived enzymes that degrade essential components of bacteria. Exebacase (Lysin CF-301) is an attractive antimicrobial agent because it demonstrates rapid bacteriolytic activity against staphylococcal species, including Staphylococcus aureus, has a low resistance profile, eradicates biofilms, and acts synergistically with other antibiotics. Combinations including exebacase and standard of care antibiotics represent an alternative to antibiotic monotherapies currently used to treat invasive staphylococcal infections. This manuscript reviews what is known about exebacase and explores how this novel agent may be used in the future to treat human bacterial pathogens.

Abstract
Despite meritorious attempts, a S. aureus vaccine that prevents infection or mitigates severity has not yet achieved efficacy endpoints in prospective, randomized clinical trials. This experience underscores the complexity of host-S. aureus interactions, which appear to be greater than many other bacterial pathogens against which successful vaccines have been developed. It is increasingly evident that S. aureus employs strategic countermeasures to evade or exploit human immune responses. From entering host cells to persist in stealthy intracellular reservoirs, to sensing the environmental milieu and leveraging bacterial or host metabolic products to reprogram host immune responses, S. aureus poses considerable challenges for the development of effective vaccines. The fact that this pathogen causes distinct types of infections and can undergo transient genetic, transcriptional or metabolic adaptations in vivo that do not occur in vitro compounds challenges in vaccine development. Notably, the metabolic versatility of both bacterial and host immune cells as they compete for available substrates within specific tissues inevitably impacts the variable repertoire of gene products that may or may not be vaccine antigens. In this respect, S. aureus has chameleon phenotypes that have alluded vaccine strategies thus far. Nonetheless, a number of recent studies have also revealed important new insights into pathogenesis vulnerabilities of S. aureus. A more detailed understanding of host protective immune defenses versus S. aureus adaptive immune evasion mechanisms may offer breakthroughs in the development of effective vaccines, but at present this goal remains a very high bar. Coupled with the recent advances in human genetics and epigenetics, newer vaccine technologies may enable such a goal. If so, future vaccines that protect against or mitigate the severity of S. aureus infections are likely to emerge at the intersection of precision and personalized medicine. For now, the development of S. aureus vaccines or alternative therapies that reduce mortality and morbidity must continue to be pursued.
