We present a case of meningitis and endocarditis caused by Streptococcus agalactiae (group B streptococcus) in an adult patient with human immunodeficiency virus (HIV) infection. To our knowledge, only four other cases of meningitis, none of which had concomitant endocarditis, have been reported so far. A 45-year-old homosexual patient presented with fever, confusion, and signs of meningeal irritation. Streptococcus agalactiae was cultured from the blood, urine, and cerebrospinal fluid (CSF). Diagnosis of meningitis caused by streptococcus agalactiae was made. On day 35, a heart murmur was noticed, and patient developed cardiac decompensation. Echocardiography revealed vegetations on the mitral and aortic valve. After nine weeks of antibiotic treatment, the patient was discharged from the hospital in good general condition, with improved CSF and echocardiographic findings.

To determine the effect of human immunodeficiency virus (HIV) infection and other factors on infective endocarditis (IE) among injection drug users (IDUs), the incidence of IE was determined according to HIV status in a cohort of IDUs. A nested case-control study assessed IE risk factors. IE incidence (117 cases) was higher among HIV-seropositive than HIV-seronegative IDUs (13.8 vs. 3.3 cases/1000 person-years) during 1988-1998. Multivariate analysis of HIV-infected case patients revealed an inverse association between IE and CD4 lymphocyte count (odds ratio [OR] for 200-499 cells/mm(3), 2.01; OR for <200 cells/mm(3), 3.61) and with alcohol intake (OR for 1-21 drinks/week, 0.43; OR for >21 drinks/week, 0.32). Women had an increased risk of IE (OR, 3.26), as did persons with increasing injection drug use frequency (OR for less than daily use, 3.15; OR for at least daily use, 6.07). This study confirms that IE is more common among IDUs with advanced HIV immunosuppression even after accounting for injection drug use behaviors.

Mycotic aneurysms of the aorta and the visceral arteries are life-threatening diseases, due to potential rupture and organ or limb ischemia. They occur in endocarditis, immunodeficiency, bacteremia and fungemia, and have a poor prognosis. We report on a case of a 54-year-old male patient suffering from abdominal angina after mitral valve replacement for septic mycotic endocarditis. In presence of a mycotic-embolic occlusion of the left popliteal artery and multiple septic organ infarctions a mycotic aneurysm of the superior mesenteric artery was found in abdominal spiral-CT. Based on sequential spiral-CT examinations, this case demonstrates the development of a septic aneurysm of the superior mesenteric artery.

Prison populations throughout the Unites States are growing; the 1990s saw an average 6.5% per year increase. Average inmate age is increasing, as are both the number and rate of inmate deaths. Aging inmates experience health concerns typical of the general, free, aging population. Inmates have higher incidence of health complications associated with various circumstances, risk behaviors, and associated medical conditions. These circumstances include prison violence, incarceration-related constraints on exercise, and diet. Inmates are more likely to have a history of alcohol abuse, substance abuse or addiction and sex industry work. Risk-behavior conditions include human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS), hepatitis B and C, liver disease, tuberculosis, endocarditis, and cardiomyopathy. Hospice is increasingly the preferred response to the health and care needs of terminally ill inmates. Implementing hospice behind bars has some unique challenges in addition to those inherent in hospice work. This series will provide an in-depth look at four hospice programs for inmates in the United States.

With more effective prophylactic treatment and an increased time of survival, noninfectious conditions associated with human immunodeficiency virus (HIV) disease are being recognized with increasing frequency in HIV patients. Cardiac involvement in HIV-infected patients varies from clinically silent to a fatal disease with a direct cardiac cause of mortality estimated at 1% to 6%. Pericardial effusion, pericarditis, myocarditis, cardiomyopathy, endocarditis, and pulmonary hypertension are known cardiac manifestations associated with HIV infection. Coronary artery disease (CAD) has not been a recognized complication of HIV disease, although some recent case reports have suggested occurrence of premature CAD and accelerated atherogenesis in HIV-infected patients. The role of protease inhibitors have been suggested in the development of this complication. After reviewing records of the last 7 years, the authors found 10 cases of acute coronary syndrome in HIV-infected patients who had no other risk factor for CAD except smoking. The presence of CAD was confirmed by angiography or autopsy. The mean CD4 count was 380 cells/mm3, and the mean duration between the diagnosis of HIV infection and CAD was 7.5 years. Four patients had single-vessel disease, 1 patient had 2-vessel disease, and 5 patients had 3-vessel disease. Three patients underwent coronary bypass surgery and 1 patient died of cardiogenic shock. CAD may be associated with HIV disease.

This report describes a 47-year-old woman with human immunodeficiency virus (HIV) and end-stage renal disease on hemodialysis, treated with combination antiretroviral drug therapy, who developed an acute, severe type B lactic acidosis 24 hours after homograft root replacement for endocarditis. She fully recovered after HIV medication was discontinued, along with administration of riboflavin and supportive measures including hemodialysis. The timing of this complication and previous reports suggest that open heart surgery may be a risk factor for nonischemic (type B) lactic acidosis in patients taking nucleoside analogue reverse transcriptase inhibitors.

The human immunodeficiency virus (HIV) does not only affect the immune system. Other organs including the cardiovascular system are influenced by the HIV as well. Most common HIV-associated cardiac manifestations are pericardial effusion and chronic active, focal or diffuse myocarditis. In addition to peri- and myocardial disease, endocardiac manifestations occur as infective endocarditis and nonbacterial thrombotic endocarditis in HIV-infected patients. Although most of the cardiac manifestations associated with HIV-infection exhibit a slow progression, rapid courses may lead to fatal complications. Early screening of HIV-infected patients will identify the potentially fatal complications of HIV disease and permit efficient treatment. The use of highly active antiretroviral therapy (HAART) significantly reduced the mortality and morbidity of HIV-infected patients. However, the impact that HAART will have on the incidence and prevalence of cardiac complications in HIV-infected patients is still unknown. It can be predicted, that the long-term viral infection and the increase of cardiovascular risk factors by HAART will probably lead to an increased prevalence of HIV-infected individuals with cardiac complications in the next decade. The present review describes the most frequent HIV-associated cardiac manifestations including diagnostic and therapeutic perspectives.

In the last years the number of Bartonella species significantly raised, often with an epidemiological profile of emergent disease. B. bacilliformis is the etiological agent of Carrion's disease. B. clarridgeiae has been associated, together with B. henselae, to Cat-Scratch Disease (CSD), whereas B. elizabethae to endocarditis and B. grahamii to neuroretinitis. B. henselae has been associated to CSD and, in patients with immunodeficiency, together with B. quintana, to bacillary angiomatosis, to peliosis and to endocarditis. B. quintana is the etiological agent of "trench fever", in its "classical" and "urban" form. B. vinsonii subsp. arupensis and subsp. berkhoffii have been associated to bacteremia and endocarditis. The diagnosis foresees pathological examination of the lesions, germ isolation and use of specific serological test and of polymerase chain reaction. Prognosis is, generally, favourable. Therapy foresees the use of numerous antibacterial agents, like: penicillins, cephalosporins, aminoglycosides, tetracyclines, macrolides, quinolones, trimethoprim-sulfomethoxazole and rifampicin.

Q fever, a worldwide zoonosis caused by Coxiella burnetii, has many manifestations in humans. Endocarditis is the most serious complication of Q fever. Animal models are limited to acute pulmonary or hepatic disease and reproductive disorders. An appropriate experimental animal model for Q fever endocarditis does not yet exist. In this study, severe combined immunodeficient (SCID) mice infected with C. burnetii showed persistent clinical symptoms and died, whereas immunocompetent mice similarly infected became asymptomatic and survived. The SCID mice examined in this study had severe chronic lesions in their primary organs: the heart, lung, spleen, liver, and kidney. The heart lesions of the SCID mice were similar to those in humans with chronic Q fever endocarditis: they had focal calcification and expanded macrophages containing C. burnetii. The 50% lethal dose of C. burnetii in SCID mice was at least 10(8) times less than that in immunocompetent mice. The SCID mouse is highly susceptible to C. burnetii, and the immunodeficiency of the host enhances the severity of Q fever. This animal model could provide a new tool for the study of chronic Q fever and Q fever in immunodeficient hosts.

Infective endocarditis associated with human immunodeficiency virus (HIV) infection occurs almost exclusively in intravenous (i.v.) drug users and usually involves the tricuspid valve, with an increased mortality rate among patients with a severe degree of immunosuppression. The first reported case of recurrent tricuspid endocarditis sustained by Streptococcus agalactiae and Enterococcus faecalis in an i.v. drug addict during HIV infection is presented. Antimicrobial therapy with i.v. ampicillin, gentamicin and teicoplanin led to complete clinical and echocardiographical recovery.
