Infective endocarditis treatment

When chronic Q fever infection is manifested by infective endocarditis, treatment is very difficult the mortality is 24% even when patients receive appropriate treatment.73 At least 2 years of therapy are required, usually with a tetracycline combined with rifampin or a quinolone, although tri-methoprim-sulfamethoxazole has also been used.84 Quinolones alone or in combination have also been effective. Most recently, the addition of hydroxychloroquine to tetracycline has shown promising results both in vitro87 and in a small number of patients.88... 

Infective endocarditis caused by these streptococci typically has a subacute clinical course. The current cure rate is often over 90% unless complications occur, which is the case in more than 30% of patients.17 The majority of viridans streptococci remain very susceptible to penicillin, with most strains having a minimum inhibitory concentration (MIC) of less than 0.125 mcg/mL.15,18 Organisms with decreased susceptibilities are increasing. Therefore, antibiotic susceptibilities need to be assessed in order to determine the most appropriate treatment regimen. 

Treatment — Various antibiotics are useful in treating Coxiella infections. They include tetracycline, doxycycline, and erythromycin. In cases of endocarditis, treatments with doxycycline combined with rifampin, and trimethoprim-sulfamethoxazole combined with doxycycline or tetracycline for 12 months or longer have been successful.3...

Opioids (heroin) are frequently used in combination with cocaine (speedball) by persons generally involved in crime. Early death may occur as a result of their use. Heroin addicts acquire bacterial infections producing skin abscesses, pulmonary infections, endocarditis, viral hepatitis, and acquired immunodeficiency syndrome (AIDS). There is a range of treatment options for heroin addiction, including medication and behavioral therapies. Methadone, a synthetic opiate medication, blocks the effects of heroin its results are encouraging. 

Other potentially nephrotoxic drugs (e.g, nonsteroidal antiinflammatory drugs) should be used with caution in patients receiving gentamicin therapy, Data for once-daily dosing of aminoglycosides for children exist, but no data for treatment of infective endocarditis exist.

Infective endocarditis is a serious complication of centrally placed venous access devices. The successful treatment in situ of a large thrombus associated with the tip of the catheter has been described (29). The antibiotic regimen was gentamicin and vancomycin, both delivered via the venous access device vancomycin was allowed to remain in situ between each 8-hourly dosing. This regimen successfully eradicated the thrombus within 3 weeks, without removal of the hue.

Imipenem inhibits bacterial cell wall synthesis. Cilastatin prevents metabolism of imipenem, resulting in increased urinary recovery and decreased renal toxicity. They are indicated in the treatment of serious infections of the lower respiratory tract and urinary tract, intra-abdominal and gynecologic infections, bacterial septicemia, bone and joint infections, skin and skin structure infections, endocarditis, and polymicrobic infections due to susceptible microorganisms. 

Ampicillin (with gentamicin for immunosuppressed patients with meningitis) and penicillin G are the drugs of choice for infections with L. monocytogenes. The dose of penicillin G is 15-20 million units parenterally per day for at least 2 weeks. With endocarditis, treatment is for at least 4 weeks. 

According to Franz et al. (1997), patients should be treated with combinations of antibiotics because treatment with a single antibiotic causes poor response or relapse. Usually, a combination of doxycycline and rifampin is given orally for six weeks. Trimethoprim-sulfamethoxazole can be substituted for rifampin, although relapse rates may be as high as 30 percent (Franz et al., 1997). The recommended treatment for bone and joint infections, endocarditis, and central nervous system disease is streptomycin or another aminoglycoside, and therapy should be extended.

ELISA) followed by Western blotting are used. As for treatment, doxicycline and rifampin for a minimum of six weeks. Ofloxacin plus rifampin is also effective. Therapy with rifampin, a tetracycline, and an aminoglycoside is indicated for infections with complications such as endocarditis or meningoencephalitis. 

Yes, but treatmert can be difficult, Doctors car prescribe effective antiiiotics. Usually, doxycvcline and rifampin are used in combination for 6 weeks to prevent reoccuring infection, Depending on the timing of treatment and severity of Blness, recovery may lake a few weeks to several months. Mortality is low (<2%), and is usually associated with endocarditis. 

Even newer is the natural product daptomycin (Cubicin), a complex cyclic lipopeptide structure, approved for use in the United States in 2003. Daptomycin has a spectrum similar to that of linezolid and specifically includes MRSA and VRE. In contrast to linezolid, daptomycin is bactericidal for these Gram-positive organisms. It is, like vancomycin, a parenteral antibiotic and is given intravenously. It is indicated for treatment of complicated skin and skin structure infections and for some cases of bacteremia, including endocarditis. Daptomycin may be thought of as an alternative to vancomycin. 

Duration - Duration of therapy varies with the type and severity of infection as well as the overall condition of the patient therefore, determine duration by the clinical and bacteriological response of the patient. In severe staphylococcal infections, continue nafcillin therapy for at least 14 days. Continue therapy for at least 48 hours after the patient has become afebrile and asymptomatic and cultures are negative. The treatment of endocarditis and osteomyelitis may require a longer duration of therapy. 

IM Treatment of serious infections of mild to moderate severity where IM therapy is appropriate. Not intended for severe or life-threatening infections, including bacterial sepsis or endocarditis, or in major physiological impairments (eg, shock). 

Clinical improvement, especially the disappearance of fever or defervescence, is the best parameter to judge the response to therapy. However, clinical improvement can be difficult to monitor objectively in critically ill patients with multi-system disease. Also, clinical improvement can be very slow for certain infections, e.g. tuberculosis. The peripheral blood leukocyte count including the presence of early stages in leucocyte differention and the level of serum C-Reactive Protein (CRP, an acute phase protein) are parameters that can be sequentially determined to monitor improvement. For monitoring the effect of treatment of chronic infections such as endocarditis or osteomyelitis, weekly determination of the erythrocyte sedimentation rate has been proven useful. 

The minimally required duration of treatment is only known for a limited number of infections. Clinical trials have shown the effectiveness of a single dose in the treatment of gonorrhoea or uncomplicated urinary tract infection in women and in surgical prophylaxis. The more precise duration of treatment has been studied for endocarditis, meningitis and staphylococcal bacteraemia. More often, guidelines for duration of treatment have been based on clinical experience with similar infections and on the parameters of response mentioned above. Failure of treatment should be recognised early. It can be due to a variety of reasons (Table 2). 

In severe bacterial infections that are difficult to eradicate, such as endocarditis or osteomyehtis, it may be important to ensure that the patient s serum remains bactericidal at the lowest, or trough, concentration in the dosing interval. Dilutions of patient s serum can be incubated with the organism isolated from the patient and the minimum bactericidal concentration determined through serial dilutions. Treatment is considered adequate if the serum remains bactericidal at a dilution of 1 8.
