We present a clinical case of a 33 years old young male, gypsy, intravenous drug abuser with heroine and cocaine and AIDS diagnosis. The clinical anamnesis was mainly fever and systolic heart murmur in a clinical scenario of AIDS. The two-dimensional echocardiographic study was clearly diagnostic of an hypertrophic obstructive cardiomyopathy of the left ventricle. This study showed also the presence of multiple vegetations of the mitral, aortic and pulmonic valves in a clinical setting of an acute Streptococcus Viridans infective endocarditis. In this case report we discuss the incidence of this type of multiple cardiac lesions and particularly the presence of this specific pathogenic agent in this high risk group of patients with intravenous drug abuse and systemic immunosuppression. We pointed out the rarity of these findings of left side valvular vegetations associated with this type of cardiomyopathy and the different factors related to infective endocarditis.

Acquired immunodeficiency syndrome affects over 10 million persons worldwide. The disease represents an enormous cost to society in health care resources and in loss from the workforce. Although initially reported in 1980 as a disease affecting mainly homosexuals and intravenous drug abusers with a predominance in males, the male to female ratio was close to parity by 1992. The disease attacks all systems in the body. Preanaesthetic evaluation focuses on assessment of lung function and presence of infection, evaluation of endocarditis and treatment of congestive failure, rehydration and correction of electrolyte imbalances, transfusion and documentation of central nervous system manifestations. The Center for Disease Control and Prevention has produced guidelines to protect health care workers from transmission of the virus. Although the risk of infection is extremely low, these precautions should be routinely adopted.

We describe the cardiovascular abnormalities found at autopsy in patients with AIDS and a description of the opportunistic infections in these cases studied between January 1988 and August 1993. There were 51 cases with such diagnosis. Pericardial effusion appeared in 9, pleural effusion in 7, myocarditis in 5, 7 with pericarditis, endocarditis in 6, left ventricular hypertrophy in 20, right ventricular hypertrophy in 21 and evidence of atherosclerosis in 15. Thus, data of cardiovascular damage was present in 42.7% of our patients. The cardiovascular abnormalities in this group are common, in contrast to the paucity of clinical findings. Diagnosis of cardiac pathology was made in only 12% of them. So in every case with diagnosis of AIDS, a careful clinical examination and cardiac diagnostic oriented tests must be done for detection of these abnormalities.

The incidence of infective endocarditis in drug addicts is increasing with the spread of intravenous drug abuse. The tricuspid valve is involved most commonly, followed by the mitral. We evaluated 22 patients prospectively with a mean age of 23 years, presenting with addiction-associated endocarditis and referred to our institution during a three-year period. The tricuspid valve was involved in 13 instances, the mitral in four, mitral plus tricuspid valves in five patients and the aortic valve in one. Staphylococcus aureus was the most frequent infective organism (15 cases), followed by streptococci (4 cases), corynebacteria (2 cases) and one case with a mixed infection. Six patients were HIV positive and 17 had evidence of chronic viral hepatitis. Ten patients (three of them HIV positive) were treated surgically. Resection of the tricuspid valve with (one case) or without replacement (four cases), resection of vegetations and tricuspid repair (two cases), mitral valve replacement (2 cases) and aortic valve replacement (one case) were performed. Operative mortality (< 30 days) was high (2/10, 20%); one patient died from cerebral hemorrhage and another from multi-organ failure. Another three patients died after a mean follow up of 10 months. In 12 patients, surgery was not attempted because of still existing intravenous drug abuse or renal and liver failure. Five of these patients died after a mean follow up of 13 months, two from septicemia, two from AIDS-related complications and one from drug overdose. The prognosis of drug-associated endocarditis treated with antibiotics is generally good.(ABSTRACT TRUNCATED AT 250 WORDS)

Due to the great number of different micro-organisms present, the oral cavity is an important source of infection. Infections caused by these micro-organisms can occur as local infections of the oral mucous membrane, local infections of the soft tissues or the bones following surgical intervention, or endocarditis due to bacteraemia following dental surgery. In the therapy of periodontal diseases, the application of antiseptic solutions is indicated to inhibit or reduce plaque accumulation. Povidone-iodine (PVP-I) solution will reduce inflammation and the progression of periodontal disease. The application of antiseptics in the oral mucous membrane is also indicated to prevent wound infections following surgical intervention in patients with leukaemia, AIDS, immunosuppressant therapy and patients undergoing anti-neoplastic radiation or chemotherapy. Some trials on the antibacterial efficacy of PVP-I in vivo showed reduction factors of log 2-3. PVP-I may therefore be recommended as an oral antiseptic. The irrigation of the gingival sulcus with an antiseptic solution is a useful complement to antibiotic prophylaxis in patients at risk of bacterial endocarditis. Many trials on the effectiveness of PVP-I on dental extraction bacteraemia have shown a significant benefit in the active group in comparison with the control group.

The incidence, aetiology and clinical significance of visceral mycoses in HIV-infected subjects were evaluated by a retrospective survey of the clinical and microbiological records of 237 consecutive AIDS patients followed-up since 1984. Seventy-four patients out of 237 (31.2%) (56 males, 18 females; 55 IV drug abusers, 7 heterosexuals, 6 homobisexuals, 3 blood recipients and 3 children with congenitally-acquired HIV infection) presented 77 different episodes of visceral fungal infection as a whole, represented by candidiasis in 56 cases (oesophageal 45, pulmonary 5, sepsis 2, eye involvement 2, endocarditis and invasive oropharyngeal infection in the remaining 2 patients), cryptococcosis in 17 cases (meningoencephalitis in all subjects, with disseminated infection in 11 of them), and aspergillosis in 4 cases (pulmonary 2, cerebral and cranio-facial in the remaining 2 patients). In 57 out of 74 patients (77%), visceral mycoses were diagnostic or concurrent with the diagnosis of AIDS. Fungal diseases, as a whole, showed a significantly higher incidence (p < 0.03) among drug abusers, whereas homobisexual men presented a significantly lower frequency (p < 0.001, chi-square test) than AIDS patients with other risk factors for HIV infection. The onset of cryptococcosis was significantly associated with the male sex (p < 0.005, Fisher exact test). All subjects suffering from a visceral mycosis were severely immunosuppressed, with a higher rate of neutropenia in patients developing Candida and Aspergillus spp. infection (23 out of 56 patients with visceral candidiasis and 3 out of 4 cases of aspergillosis had an absolute neutrophil count lower than 1500 cells/mm3), while a severe reduction in CD4+ lymphocyte count was more evident among patients with cryptococcosis (13 out of 17 patients had a CD4+ cell count lower than 50/mm3). After remission of the primary episode of fungal infection (obtained in 80.5% of cases), the incidence of relapse observed in a long follow-up period (mean time 57.6 +/- 39.2 weeks) was elevated both for patients with cryptococcosis (7 cases out of 17) and subjects with candidiasis (19 cases out of 53), with no significant difference among patients receiving a secondary prophylaxis or not (22 relapses observed in 53 patients treated with maintenance antifungals versus 4 episodes in 8 patients followed for a comparable mean time with no antimycotic treatment). Fifty-two out of 74 patients (70.3%) have died up to now; in 21 of them death was due to or associated with the visceral mycosis (cryptococcosis in 11 cases, candidiasis in 8, aspergillosis in 2).(ABSTRACT TRUNCATED AT 400 WORDS)

Two women and two men were infected with the human immunodeficiency virus type 1 (HIV-1) transmitted by renal transplantation from i.v. drug-addicted donors in 1984. The four recipients were treated with cyclosporine and methylprednisolone (one patient only for three months because of early graft failure). Two patients died 66 and 74 months after transplantation, one of endocarditis and one of cerebral hemorrhage. Despite several infections including urinary tract infection (n = 8), peritonitis (n = 1), shunt infection (n = 1), bronchitis (n = 1), salmonellosis (n = 1), herpes stomatitis (n = 2), herpes zoster (n = 1), and cytomegalovirus (n = 1), and despite treatment of several rejection episodes (n = 8), none of them had or has infections typical of the acquired immunodeficiency syndrome (AIDS). However, two patients developed cervical lymphadenopathy and one autoimmune thrombocytopenia 15-20 months after HIV-1 infection. Their T helper cell counts (355/microliters to 75/microliters) and helper/suppressor T cell ratios (1.0-0.2) are distinctly lowered. One patient has membranous glomerulopathy with virus-like particles within and on the outside of the basement membrane and tubuloreticular inclusions in glomerular endothelial cells. We evaluated the case reports of 53 patients with HIV-infection caused by an infected transplant or by blood transfusions during or shortly after transplantation. The cumulative incidence of AIDS was significantly lower in 40 transplant patients with an immunosuppressive regimen including cyclosporine than in 13 transplant patients receiving immunosuppressive treatment without cyclosporine (5-year cumulative risk of AIDS: 31% versus 90%, P = 0.001).

To prove the hypothesis that cardiopulmonary bypass may accelerate the development of acquired immunodeficiency syndrome (AIDS) in the human immunodeficiency virus carrier, the clinical course of 40 patients positive for human immunodeficiency virus who underwent cardiac operations between 1986 and 1992 was analyzed, especially in regard to the progression to AIDS. Mean age was 30 years (range, 19 to 61 years). Thirty-four patients (85%) were intravenous drug abusers; in 4 (10%) transmission of infection was sexual, and in 2 (5%) it was through a contaminated blood transfusion. Valve procedures were performed in 38 patients (95%), mostly for endocarditis in drug addicts. Hospital mortality was 20% (8 patients). The 32 survivors have been followed up a mean of 21 months (range, 4 months to 6 years). Four patients (12.5%) experienced progression to AIDS during the follow-up period. Actuarial progression to AIDS is 5% (+/- 5%) at 1 year, 20% (+/- 10%) at 2 years, and 40% (+/- 19%) at 5 years. There have been 8 late deaths (5 due to recurrent endocarditis, 2 due to AIDS, and 1 due to overdose). Actuarial survival is 79% (+/- 8%) at 1 year, 60% (+/- 11%) at 2 years, and 48% (+/- 14%) at 5 years. The results indicate that progression to AIDS in the patient positive for human immunodeficiency virus is not accelerated by the use of cardiopulmonary bypass. The poor prognosis in these patients is mainly related to the particular pathological conditions that often affect the drug addict population.

Fifty patients in stage IV of HIV infection (including 41 AIDS patients) were prospectively studied by echocardiography. Thirteen of them showed abnormalities: 4 had pericardial effusion, 1 endocarditis, 7 myocardial disorders and 1 primary pulmonary arterial hypertension. Pericardial effusion, also present in patients who had pleuropulmonary Kaposi's sarcoma, was not specific. Myocardial disorders concerned the diastolic function in 1 case, the segmental kinetics in 2 cases and the whole systolic function in 4 cases (3 had congestive myocardiopathy and 1 had transient systole alteration without left ventricular dilatation). The mechanism of global left ventricular disorders was multifactorial, and several hypotheses were discussed: infectious myocarditis, adrenergic or nutritional deficiency myocarditis, cardiotoxicity of antiviral drugs, common pathology with HIV encephalopathy. The prognosis of congestive myocardiopathy was poor in AIDS patients and undetermined in stage IV non-AIDS patients. Echocardiography is capable of detecting these lesions, and its use may contribute to a better care of these patients.

Endocarditis is not usually considered a complication of AIDS. Because salmonellal bacteremia is common in HIV-infected patients and because salmonellae have a propensity to adhere to endothelial cells, these patients are at risk of endocarditis and endarteritis. We report two cases of endocarditis due to Salmonella enteritidis and review three previously reported cases. All five patients had underlying heart valve disease and developed fever, breakthrough or relapsing bacteremia, heart murmurs, and cardiac failure; four of five patients were older than 45 years. One patient died, but the other four were successfully treated with beta-lactam agents alone or in combination with aminoglycosides or with ofloxacin (valve replacement was not required). As AIDS patients get older, the number of cases of endocarditis or endarteritis due to Salmonella species may increase, particularly in geographic areas where Salmonella species are prevalent.
