We report a PVL-secreting S. aureus superinfection in a patient who had COVID-19. 2015;20(6):47680. This literature review focuses on the salient features of diagnosis and management, with particular attention to the choice of antimicrobials. Spiramycin was added to the previous drug regimen. https://doi.org/10.1136/bcr-2017-222138. Clin. The PCR result was positive for SARS-CoV-2 (4). None of the strains harboured the genes encoding Panton-Valentine leukocidin. https://doi.org/10.1111/j.1469-0691.2007.01947.x. An official website of the United States government. [16][17], Genetic analysis shows that PVL CA-MRSA has emerged several times, on different continents, rather than being the worldwide spread of a single clone. PVL is associated with skin and soft tissue infections but not with bacteremia, which suggests that PVL is not likely to be involved in the pathogenesis of bacteremia. This antibiotic regimen was continued for 2 weeks and then with only intravenous ceftaroline for others 4 weeks. Cookies used to make website functionality more relevant to you. The Prevalence of Panton-Valentine Leukocidin (PVL) gene among Staphylococcus aureus Strains Isolated from Both Medical staff and Community People in Minia Governorate, Egypt January 2023 DOI: 10. . View data is from . In PVL-producing S. aureus superinfection, prescribing antimicrobial drugs that have an antitoxin effect, such as clindamycin or linezolid, remains essential (2). and transmitted securely. The Altmetric Attention Score for a research output provides an indicator of the amount of attention that it has received. Methicillin-resistant S. aureus (MRSA) accounted for 19% of S. aureus isolates, associated with mostly staphylococcal cassette chromosome mec (SCCmec) type IV, or V. Panton-Valentine leukocidin (PVL) genes were detected in methicillin-susceptible S. aureus (MSSA) at significantly higher rate (39%) than in MRSA (22%). All isolates had community-associated pulsed-field gel electrophoresis patterns; all MRSA isolates had the staphylococcal cassette chromosome mec type IVa. What is Staphylococcus aureus? Pragmatic management of Panton-Valentine leukocidin-associated staphylococcal diseases. 2007;13:594-600. PVL is a pore-forming toxin that causes damage to the membrane of leukocytes, leading to the destruction of white blood cells and tissue necrosis. It includes nasal mupirocin 2% ointment and chlorhexidine 4% body wash [27, 32]. Privacy In our case, the origin of the infection is not clear, as previous hospitalizations maybe a risk factor. J Pathog. Pediatr Infect Dis J. Springer Nature. Strains were obtained from healthy children (<19 years) and elderly persons (>55 years). Thus, in previously healthy young adults admitted to an ICU for COVID-19 and S. aureus superinfection, a PVL-producing strain should be assumed and treatment provided accordingly. Correa-Jimnez, O., Pinzn-Redondo, H., & Reyes, N. (2016). The .gov means its official. 2018;51(1):1625. Once diagnosed, PVL-SA infection must be treated appropriately, without delay. Careers.

While PVL-positive strain might have a lesser propensity to cause pneumonia compared with skin and soft-tissue infection . Ravishankar S, Chapin K, Alexander-Scott N, Wills H, Merritt C, Jacobson M, et al. Whether the prevalence of PVL in carriage- and blood-culture isolates is higher and differs among distinct genetic clusters of S. aureus in countries with endemic CA-MRSA has to be investigated further. https://doi.org/10.12968/hmed.2015.76.1.18. Etiologic diagnosis took up to five years; meanwhile, 42% of patients had antibiotic treatments. Multi-locus sequencing typing (MLST), spa typing and testing for the Panton Valentine Leukocidin (PVL) gene was performed on all strains. Panton-Valentine Leukocidin (PVL) is a toxin produced by some strains of Staphylococcus aureus (S. aureus).The bacterium can cause cellulitis, abscesses, boils and carbuncles. Because of this necrotizing pneumonia associated with acute respiratory distress syndrome, a PVL-producing strain was suspected.

The https:// ensures that you are connecting to the To investigate the role of PVL in pulmonary disease, we tested the pathogenicity of clinical isolates . All carriage and clinical isolates (n = 1,033) were mecA negative. Staphylococcus aureus (SA) is one of the major cause of bacterial infections in humans [1]. The PVL positivity rate is 77100% in community-associated MRSA infections, while it is less than 4% in hospital-associated MRSA infections [10]. Similar isolates caused a recent Irish hospital outbreak. 2007 May-Jun;65(3):277-81. Unfortunately, antibiotic treatment alone is often insufficient, as antibiotic distribution is reduced in necrotic tissue. Panton-valentine leukocidin Staphylococcus aureus severe infection in an infant: a case report and a review of the literature. Pediatr Infect Dis J. The WB-MRI performed 6 months later showed a complete radiological resolution. Disseminated Panton-valentine Leukocidin-positive Staphylococcus aureus infection in a child. Laura Shallcross and colleagues1 concluded on the basis of their meta-analyses that individuals with pneumonia were less likely to be infected with a Panton-Valentine leucocidin (PVL)-positive Staphylococcus aureus strain than are those with skin and soft-tissue infection. Ital J Pediatr. We report 2 outbreaks of Panton-Valentine leukocidin-positive, doxycycline-resistant, methicillin-susceptible Staphylococcus aureus infections in French soldiers operating in Cte d'Ivoire. The child in his first 5 months of life reported four hospitalizations: the first because of an episode of apnoea, the second due to an upper respiratory tract infection, the third and the last one because of two episodes of bronchiolitis. The stool culture, the research of viruses on faeces and isolation of respiratory viruses on nasopharyngeal aspirate were performed and resulted negative. A blood culture was also performed. https://doi.org/10.2350/15-06-1652-CR.1. We changed antimicrobial drug therapy to oxacillin plus clindamycin (for antitoxin effect) against methicillin-susceptible S. aureus and lopinavir/ritonavir (quickly stopped because of suspected toxicity) plus azithromycin against SARS-CoV-2.

[7], PVL is a member of the synergohymenotropic toxin family that induces pores in the membranes of cells. However, the patient died 17 days after his admission to the hospital. (2006). Emerg Infect Dis. PVL-SA strains can be identified by detection of genes encoding PVL or the toxin itself [9]. gp ct trong word 2003 - pneumonia [11, 12]. Melles DC, van Leeuwen WB, Boelens H, et al. Pneumonia caused by methicillin-resistant Staphylococcus aureus (MRSA) strains producing a cytotoxin known as Panton-Valentin leukocidin (PVL) is a severe and difficult to treat disease. Most patients were adult males, had relevant travel history, reported recurrent disease and presented with SSTI. 2 . We chose ceftaroline as anti-MRSA agent as it is effective and safe similarly to vancomycin [28, 29]. All SAs, including PVL-SAs, can cause harm if they get an opportunity to enter the body, for example through a cut or a graze. A copy of the written consent is available for review by the Editor-in-Chief of this journal. PVL-SA infection mainly occurs in young, healthy individuals, but it can affect other patient groups including children. A literature review starting . Data sharing was not applicable to this case report because no datasets were generated or analysed during the study. Panton Valentine leukocidin (PVL) is a cytotoxin, one of the -pore forming toxins (Panton and Valentine, 1932), and its presence is associated with increased virulence of certain strains of S. aureus. The score is derived from an automated algorithm, and represents a weighted count of the amount of attention Altmetric picked up for a research output. Clin Infect Dis. doi: 10.1016/j.cmi.2015.01.016. This finding is also in agreement with the proposed involvement of PVL in severe and invasive (soft tissue) staphylococcal infections (13). What is an abscess? 8600 Rockville Pike In our patient, the genotype of the PVL-MRSA was ST121, that is, to our knowledge, the first reported in a paediatric patient in Italy.

The Panton Valentine leukocidin was named after Sir Philip Noel Panton and Francis Valentine who associated it with soft tissue infections in 1932 [2, 3]. These toxins form pores in the membrane of host defense cells by synergistic action of 2 secretory proteins, designated LukS-PV and LukF-PV, which are encoded by 2 cotranscribed genes of a prophage integrated in the S. aureus chromosome (5).
