Brucella endocarditis is a rare, but often fatal, complication of brucellosis. A 32 year old man acquired brucellosis while on a visit to his former home in Greece and presented six months later with malaise, fever and aortic regurgitation. Blood cultures grew Brucella melitensis biotype 1. Combined chemotherapy with streptomycin, tetracycline and rifampin sterilized his blood; however, his aortic valve was replaced owing to recurrent emboli and cardiac failure. Over the next 18 months the patient's antibody titer to Brucella fell and his blood reamined sterile. Cure was achieved by resection of the infected aortic valve and 10 weeks of bactericidal therapy for B. melitensis.

We report a case of brucella endocarditis on a native aortic valve causing severe aortic regurgitation, uncontrolled heart failure and disseminated intravascular coagulopathy. The diagnosis was proven by positive serology, isolation of Brucella melitensis from preoperative blood cultures and excised valve. The patient was successfully treated with valve replacement and specific antibiotic therapy.

Of 511 cases of brucellosis studied between December 1983 and February 1986, four (0.8%) had sternoclavicular (STCL) arthritis. Two were male and two female, and only one was younger than 50 years old. All four cases had significantly high specific IgG antibody titres (1 of 1280), measured by the indirect immunofluorescent (IIF) test, and two had Brucella melitensis isolated from their blood. In two cases, STCL arthritis was the presenting problem, and it was associated in one with ankle arthritis, hepatitis, renal impairment, orogenital ulcers and a haematological picture of myelodysplasia; in the other it was a relapsing STCL arthritis. In the remaining two cases, STCL arthritis was part of an extensive osteoarticular disease, which was associated in one with cachexia, liver cirrhosis, heart failure and prostatitis with urine retention, and in the other with severe thrombocytopenia. Excellent results were obtained from six to eight weeks' therapy with streptomycin, rifampicin and cotrimoxazole or tetracycline.

Cardiac transplantation has been rarely performed in patients with infective endocarditis. A 31-year-old man developed aortic endocarditis due to Brucella melitensis. He presented with fever and developed acute myocardial infarct, severe aortic regurgitation, and heart failure. Aortic valve replacement did not improve cardiac function; hence, an emergent cardiac transplantation was carried out. Eighteen years later, he is doing well and living an active and productive life. Only 6 patients have received a cardiac transplant as part of the treatment of active infective endocarditis. This patient shows how cardiac transplantation may be successfully used as salvage therapy for patients with infective endocarditis who are not candidates for valve replacement or have severe and irreversible myocardial damage.

With increasing rates of device implantation, there is an increased recognition of device infection. We conducted a retrospective observational study in a tertiary care center in Lebanon, with data collected from medical records of patients presenting with cardiac implantable electronic device (CIED) infection from 2000 to 2017 with the purpose of identifying etiologies, risk factors and other parameters, and comparing them to available data from the rest of the world. We identified a total of 22 CIED infections. The most common microbial etiologies, including involvement in polymicrobial infection, were coagulase-negative staphylococci (45.5%) and Staphylococcus aureus (22.7%). Rare cases of Brucella melitensis, Sphingomonas paucimobilis, and Kytococcus schroeteri device infection were seen. Heart failure was seen in 77.3% of patients, hypertension in 68.2%, and chronic kidney disease in 50%. Skin changes were the most common presenting symptoms (86.4%). Antibiotics were given to all patients and all had their devices removed, with 36.4% undergoing new device implantation. This is the first study of CIED infections in Lebanon and the Middle East. Local epidemiology and occupational exposure must be considered while contemplating the microbial etiology of infection. Close monitoring after device implantation is important in preventing device infection that carries high risk of morbidity and mortality.
