An adult drug abuser with endocarditis due to a group II Staphylococcus aureus developed the staphylococcal scalded skin syndrome (SSSS). Studies of the patient's immune function found cell-mediated immunity (CMI) to be essentially normal; thus, previous suggestions that deficient CMI is required in adults who develop SSSS seem unfounded. Pathogenesis, diagnosis, and therapy of SSSS and its differentiation from drug-induced hypersensitivity reaction are discussed in detail.

An exfoliatin B-producing strain of Staphylococcus aureus was isolated from two adults with typical staphylococcal scalded skin syndrome (SSSS). One patient developed desquamation after a local staphylococcal infection of the hand, and the other developed exfoliation after nosocomially acquired staphylococcal endocarditis. Neither patient was immunocompromised, had evidence of renal insufficiency, or manifested other potential risk factors for SSSS. Purified toxin, isolated from the causative organisms, produced a Nikolsky sign in neonatal mice. The toxins were shown to be exfoliatin B by biochemical and immunologic methods and heretofore had been described only in children with SSSS. Analysis of plasmid DNAs from both strains revealed a 23-megadalton plasmid with identical restriction endonuclease digestion fragments. One isolate belonged to phage group II (3B/3C/6/7/47/54/55), whereas the other isolate belonged to phage groups I and III (7/29/52/52A/53/54/80). The observation that a non-phage group II exfoliatin-producing strain of S. aureus may produce SSSS in adults indicates the need to better define the diagnostic criteria for SSSS. Immunocompetent adults may remain susceptible to some strains of exfoliatin B-producing S. aureus.

We report staphylococcal scalded skin syndrome (SSSS) in a 67-year-old man. He showed diffuse erythema with erosion on his face and erythema with giant desquamation on his neck, axilla, genitalia, chest and abdomen 39 days after a coronary artery bypass graft and aortic valve replacement. He died of cardiac rupture caused by myocardial necrosis, and autopsy findings demonstrated prosthetic valve endocarditis due to a strain of exfoliative toxin-B producing methicillin-resistant Staphylococcus aureus. To the best of our knowledge, this is the first case of SSSS caused by prosthetic valve endocarditis.

Staphylococcus aureus is a dreadful pathogen for mankind, causing boils, abscesses, wound infections, osteomyelitis, septicaemia, endocarditis, pneumonia, toxic shock syndrome, scalded skin syndrome, and food poisoning. The development of penicillin-, methicillin-, and vancomycin-resistant strains shows that S. aureus has an enormous adaptive power. Most methicillin-resistant strains of S. aureus (MRSA) are hospital-acquired, although an increasing number are reported to be community-acquired. A limited number of clones of MRSA have spread all over the world. Since most community-acquired MRSA can be traced back to some contact with health care, MRSA can still best be combatted by control measures in health care institutions. In this respect, the Netherlands and Scandinavian countries have been very successful so far. S. aureus has many virulence factors at its disposal: structural components, enzymes and three types of toxins. Panton-Valentine leukocidin (PVL) has received attention as a factor causing severe pneumonia with high mortality. A strain combining methicillin resistance and PVL has spread through France. Recently, the genome of an MRSA strain has been unravelled. Its structure illustrates how well S. aureus can adapt itself and acquire properties of other microorganisms. This genetic knowledge may lead to new strategies to combat S. aureus.

Staphylococcus aureus strains are present in the nose of 30% of healthy humans and are responsible for skin and soft tissue infections. Deep seated infections secondarily occurred such as osteomyelitis or infective endocarditis. New toxin-associated clinical entities have been recognized such as the toxin shock syndrome, the staphylococcal scarlet fever, the staphylococcal scalded skin syndrome or the necrotising pneumonia. This later syndrome is associated with Panton Valentine leukocidin producing strains. It occurs mainly in children and has a lethality of 75%. New antibiotic resistances are also emerging, for vancomycin in hospital-acquired infections and for methicillin in community-acquired infections.

Staphylococcal scalded skin syndrome (SSSS) is an extensive desquamative erythmatous condition caused by the Staphylococcus aureus exfoliative toxin. Although adult cases of SSSS are rare, the mortality rate is high. We report herein on a case of SSSS due to long-term catheter-related bloodstream infection caused by exfoliative toxin B, which produced methicillin-resistant Staphylococcus aureus. A 64-year-old man was admitted to our hospital with a high fever and generalized exfoliative dermatitis. He had an implanted port vascular access device in his left arm. The port was removed because it was thought to be the focus of infection. A Gram stain of the pus from the incision site revealed Gram positive coccus in clusters, and we administered intravenous vancomycin. MRSA was isolated from blood cultures and the pus, and histiology of a skin biopsy specimen from the exfoliation dermatitis showed epidermal detachment in the uppermost layer, which was consistent with SSSS. Although the patient developed infective endocarditis and septic embolisms, he eventually recovered. PCR of the MRSA was positive for exfoliative toxin B, and we finally diagnosed an adult case of SSSS due to exfoliative toxin B producing MRSA.

Staphylococcus aureus is a gram positive bacterium. It is the leading cause of skin and respiratory infections, osteomyelitis, Ritter's disease, endocarditis, and bacteraemia in the developed world. We employed combined studies of 3D QSAR, molecular docking which are validated by molecular dynamics simulations and in silico ADME prediction have been performed on Isothiazoloquinolones inhibitors against methicillin resistance Staphylococcus aureus. Three-dimensional quantitative structure-activity relationship (3D-QSAR) study was applied using comparative molecular field analysis (CoMFA) with Q2 of 0.578, R2 of 0.988, and comparative molecular similarity indices analysis (CoMSIA) with Q2 of 0.554, R2 of 0.975. The predictive ability of these model was determined using a test set of molecules that gave acceptable predictive correlation (r2 Pred) values 0.55 and 0.57 of CoMFA and CoMSIA respectively. Docking, simulations were employed to position the inhibitors into protein active site to find out the most probable binding mode and most reliable conformations. Developed models and Docking methods provide guidance to design molecules with enhanced activity.
