Abcess Case Study

24-year old male athlete

Background

  • Patient is a 24-year-old male college football player who is otherwise healthy. He has commercial insurance.

Presentation

  • The patient presented to the ED with swelling, erythema, and a painful lesion on the left upper extremity. He states that he acquired the lesion after playing in a game 3 days before.

Evaluation

  • Left upper extremity large abscess with surrounding cellulitis and brawny edema
  • Lesion size: 110 cm2
  • Temp: 101.1° F
  • BP: 130/84 mmHG
  • RR: 17/min
  • HR: 110/min
  • WBC: 11,500/mcL
  • Incision and drainage performed but minimal return and brawny edema persists

Diagnosis and treatment considerations

  • Abscess with cellulitis
  • Presumed gram-positive cocci, presumed MRSA
  • Physician assessed severity of infection warrants an IV antibiotic
  • Patient prefers not to be admitted or have to return for multiple infusions

Actual SOLO patient picture

This hypothetical case study is meant to be illustrative of an actual patient treated with a single 1200mg dose of ORBACTIV® in the SOLO trials. It is not intended to offer medical advice. Determination of appropriate treatment is at the discretion of the physician. Results presented are consistent with results observed in the SOLO trials of patients with ABSSSI. In the SOLO I and SOLO II trials the clinical response rates at 14-24 days for patients receiving ORBACTIV® were 79.6% and 82.7% respectively.

INDICATION

ORBACTIV® (oritavancin) is indicated for the treatment of adult patients with acute bacterial skin and skin structure infections (ABSSSIs) caused or suspected to be caused by susceptible isolates of the following Gram-positive microorganisms: Staphylococcus aureus (including methicillin-susceptible [MSSA] and -resistant [MRSA] isolates), Streptococcus pyogenes, Streptococcus agalactiae, Streptococcus dysgalactiae, Streptococcus anginosus group (includes S. anginosus, S. intermedius, and S. constellatus), and Enterococcus faecalis (vancomycin-susceptible isolates only).

Important Safety Information

Contraindications

Use of intravenous unfractionated heparin sodium is contraindicated for 120 hours (5 days) after ORBACTIV® administration because the activated partial thromboplastin time (aPTT) test results are expected to remain falsely elevated for approximately 120 hours (5 days) after ORBACTIV® administration.

ORBACTIV® is contraindicated in patients with known hypersensitivity to ORBACTIV®.

Warnings and Precautions

Coagulation test interference: ORBACTIV® has been shown to artificially prolong aPTT for up to 120 hours, and may prolong PT and INR for up to 12 hours, and ACT for up to 24 hours. ORBACTIV® has also been shown to elevate D-dimer concentrations up to 72 hours.

Hypersensitivity reactions have been reported with the use of antibacterial agents including ORBACTIV®. Discontinue infusion if signs of acute hypersensitivity occur. Monitor closely patients with known hypersensitivity to glycopeptides.

Infusion Related Reactions: Administer ORBACTIV® over 3 hours to minimize infusion-related reactions. Stopping or slowing the infusion may result in cessation of these reactions.

Clostridium difficile-associated diarrhea: Evaluate patients if diarrhea occurs.

Concomitant warfarin use: ORBACTIV® has been shown to artificially prolong PT and INR for up to 12 hours. Patients should be monitored for bleeding if concomitantly receiving ORBACTIV® and warfarin.

Osteomyelitis: Institute appropriate alternate antibacterial therapy in patients with confirmed or suspected osteomyelitis.

Prescribing ORBACTIV® in the absence of a proven or strongly suspected bacterial infection is unlikely to provide benefit to the patient and increases the risk of development of drug-resistant bacteria.

Adverse Reactions

The most common adverse reactions (≥3%) in patients treated with ORBACTIV® were headache, nausea, vomiting, limb and subcutaneous abscesses, and diarrhea.
