Recovery of a 10-year-old girl from methicillin-resistant Staphylococcus aureus sepsis in response to low-dose ceftaroline treatment.

ABSTRACT: A 9-year-old girl was severely injured in a car accident in Afghanistan, in which both her lower legs were badly damaged. She was treated at the Hospital of Ingolstadt (Klinikum Ingolstadt) after she had undergone initial surgery at an Indian hospital. Various bacterial species were isolated from multiple wounds, and methicillin-resistant Staphylococcus aureus (MRSA) was one among them. After the amputation of her lower legs, she developed MRSA sepsis, which was successfully treated with a relatively low dosage of ceftaroline (Zinforo(®)/Teflaro(®); 2×9 mg/kg/d), although the bacterial isolate's minimal inhibitory concentration (1.5-4 mg/L) suggested a decreased susceptibility. In summary, ceftaroline was highly efficient and well tolerated by the patient suffering from MRSA sepsis.

Project description:Methicillin resistant Staphylococcus aureus (MRSA) may be found on the skin, nose, and throats of long-term hospitalized patients. While MRSA infections are usually minor, serious infections and death may occur in immunocompromised or diabetic patients, or after exposure of MRSA to blood. This report demonstrates that the antimicrobial peptide (AMP) epinecidin-1 (Epi-1) efficiently protects against MRSA infection in a pyemia pig model. We first found that Epi-1 exhibits bactericidal activity against MRSA. Next, pharmacokinetic analysis revealed that Epi-1 was stable in serum for 4 h after injection, followed by a gradual decrease. This pharmacokinetic profile suggested Epi-1 may bind serum albumin, which was confirmed in vitro. Harmful effects were not observed for doses up to 100 mg/kg body weight in pigs. When Epi-1 was supplied as a curative agent 30 min post-infection, MRSA-induced abnormalities in blood uric acid (UA), blood urea nitrogen (BUN), creatine (CRE), GOT, and GPT levels were restored to normal levels. We further showed that the bactericidal activity of Epi-1 was higher than that of the antibiotic drug vancomycin. Epi-1 significantly decreased MRSA counts in the blood, liver, kidney, heart, and lungs of infected pigs. Elevated levels of serum C reactive protein (CRP), proinflammatory cytokine IL6, IL1?, and TNF? were also attenuated by Epi-1 treatment. Moreover, the MRSA genes, enterotoxin (et)-A, et-B, intrinsic methicillin resistance A (mecA), and methicillin resistance factor A (femA), were significantly reduced or abolished in MRSA-infected pigs after treatment with Epi-1. Hematoxylin and eosin staining of heart, liver, lung, and kidney sections indicated that Epi-1 attenuated MRSA toxicity in infected pigs. A survival study showed that the pyemia pigs infected with MRSA alone died within a week, whereas the pigs post-treated with 2.5 mg/kg Epi-1 were completely protected against death. The present investigation, thus, demonstrates that Epi-1 effectively protects pyemia pigs against pathogenic MRSA without major toxic side effects.
