The classic antibiotic combination for bone infections caused by Staphylococcus aureus and P. aeruginosa is levofloxacin plus rifampicin.
In chronic osteomyelitis, IV therapy for 2-6 weeks, followed by oral antibiotics for a total of 4-8 weeks, may be required. Prolonged courses may be required in neonates, immunocompromised or malnourished patients, patients with sickle cell disease, and patients with distant foci of infection (eg, endocarditis).
Overall, most antibiotics, including amoxicillin, piperacillin/tazobactam, cloxacillin, cephalosporins, carbapenems, aztreonam, aminoglycosides, fluoroquinolones, doxycycline, vancomycin, linezolid, daptomycin, clindamycin, trimethoprim/sulfamethoxazole, fosfomycin, rifampin, dalbavancin, and oritavancin, showed good ...
Antibiotics are taken for at least 4 to 6 weeks, often at home through an IV (intravenously, meaning through a vein).
The most common treatments for osteomyelitis are surgery to remove portions of bone that are infected or dead, followed by intravenous antibiotics given in the hospital.
Acute hematogenous osteomyelitis can be treated with antibiotics alone. Chronic osteomyelitis, often accompanied by necrotic bone, usually requires surgical therapy.
Chronic osteomyelitis usually occurs after an acute episode of osteomyelitis when the infection has not been totally cured, and is sometimes associated with a draining sinus tract. There may be bone pain, swelling, redness and tenderness of the affected area.
Long-term Considerations for Osteomyelitis
Fractures of the affected bone. Stunted growth in children (if the infection has involved the growth plate) Gangrene infection in the affected area.
An infection in your bone can impede blood circulation within the bone, leading to bone death. Areas where bone has died need to be surgically removed for antibiotics to be effective. Septic arthritis. Sometimes, infection within bones can spread into a nearby joint.
For treatment of infection due to penicillin-resistant enterococci, the preferred agent is vancomycin; daptomycin or teicoplanin (where available) are acceptable alternative agents.
The cornerstone of the treatment of chronic osteomyelitis is surgical management (Table 2). This should include an adequate surgical debridement to remove all pathogens along with their biofilms and sequestra (dead bone) that act as a foreign material, reaching down to healthy and viable tissue (Fig.
Trimethoprim-sulfamethoxazole was indicated to be successful in the treatment of osteomyelitis in patients with MRSA infected orthopedic implants either alone or in combination with other antibiotics (Sato et al., 2019).
Reactivation of osteomyelitis, even after a 50-year disease-free interval, has been reported in the literature (6). In daily clinical practice, these recurrences are not rare and usually occur at the prior anatomical site of infection without any history of concomitant disease, bacteremia, or new trauma.
Acute osteomyelitis typically refers to an infection of less than 1 month's duration, whereas chronic osteomyelitis refers to infection that lasts longer than 4 weeks.
Abstract. The standard recommendation for treating chronic osteomyelitis is 6 weeks of parenteral antibiotic therapy.
Osteomyelitis is a painful bone infection. It usually goes away if treated early with antibiotics. If not, it can cause permanent damage.
The infection spreads to the bone after several days or weeks. This type of spread is particularly likely to occur in older people. Such an infection may start in an area damaged by an injury or surgery, radiation therapy, or cancer or in a skin ulcer (particularly a foot ulcer) caused by poor circulation or diabetes.
Many bone infections are cleared with medication, surgery, or a combination of the two. However, for some people, osteomyelitis may never completely go away. The bacteria or fungi can lie dormant in the body and return, even after treatment.
Osteomyelitis is a serious infection of the bone that can be either acute or chronic. It is an inflammatory process involving the bone and its structures caused by pyogenic organisms that spread through the bloodstream, fractures, or surgery.
Bone infection can be difficult to treat because bacteria are constantly changing to fight the new antibiotics that are used to kill them. Some bacteria have been extremely difficult to kill, including methicillin-resistant Staphylococcus aureus species and vancomycin-resistant enterococci.
Osteomyelitis surgery treats bone infection by draining pus and cleaning the medullary space (marrow cavity) and then removing any dead bone in the area of the infection, followed by two to three months of antibiotics. Our orthopedic surgeons are specially trained to manage difficult bone infections and bone defects.
In adults, the vertebrae are the most common site of hematogenous osteomyelitis, but infection may also occur in the long bones, pelvis, and clavicle. Primary hematogenous osteomyelitis is more common in infants and children, usually occurring in the long-bone metaphysis.
Types of osteomyelitis include: Acute: This infection comes on suddenly. You may have a fever and then develop pain in the infected area days later. Chronic: Chronic osteomyelitis is a bone infection that doesn't go away with treatments.
Adults with acute osteomyelitis usually are given a penicillinase-resistant penicillin, ampicillin, or cephalosporin in doses of 8-12 g/day for four to six weeks. Carefully monitored oral drug therapy following initial injectable antibiotic therapy has been shown to be effective in children.
