Mean age at onset was Overall, 89 patients 59 per cent developed a cerebellar haemagioblastoma, 89 59 percent a retinal angioma, 43 28 percent renal cell carcinoma, 20 13 per cent spinal haemangioblastoma and 11 7 per cent a phaeochromocytoma. Renal, pancreatic and epididymal cysts were frequent findings but their exact incidence was not accurately assessed. Mean age at diagnosis of renal cell carcinoma The probability of a patient with von Hippel-Lindan disease developing a cerebellar haemangioblastoma, retinal angioma or renal cell carcinoma by age 60 years was 0.
A comprehensive screening protocol for affected patients and at-risk relatives is presented, based on detailed analysis of age at onset data for each of the major complications. Median actuarial survival was 49 years, with renal cell carcinoma the leading cause of death.

Valvular predisposing conditions also included the presence of a prosthetic valve in patients Chronic intravenous access was as common as intravenous drug use in the overall cohort; of patients Clinical and laboratory findings on admission are presented in Table 3.
The classic signs that are often considered diagnostic for IE were infrequent. In of the patients Of the patients In addition to blood culture information, serologic tests and valve cultures were performed in a minority of cases. Of the patients, The causative microorganisms isolated from blood cultures are shown in Table 4. Gram-positive organisms were predominant Staphylococcus aureus was also the most common organism in each major risk group, including intravenous drug users and those with intracardiac devices Table 5.
Positive serologic tests for Coxiella burnetii were reported for 27 patients 17 from Europe, 2 from North America, 1 from South America, and 7 from other regions , but only 9 were reported to have reciprocal antibody titers of more than Similarly, 22 patients had positive serologic tests for Bartonella species 18 from Europe, 1 from South America, and 3 from other regions , but only 3 were reported to have reciprocal antibody titers of more than One case of infection was due to Tropheryma whippelii.
Staphylococcus aureus was the most common organism in 3 of 4 regions, whereas viridans group streptococci were the most common organisms isolated from patients in South America.
The frequency of Streptococcus bovis —associated IE was much higher in Europe and South America compared with the other regions, and IE due to the group of bacteria consisting of Haemophilus species, Aggregatibacter formerly Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, and Kingella species HACEK bacteria was relatively uncommon in North America. Most of the C burnetii and Bartonella infections were from Europe.
The location of acquisition was determined in North America had a much higher proportion of health care—associated infections The microbial causes of IE varied with location of acquisition, with a higher proportion who had staphylococcal IE and a lower proportion who had viridans streptococcal IE among those with health care—associated IE.
Among patients with community-acquired infection, Echocardiography was used in most patients More than one-half Abscess was the most common paravalvular complication Congestive heart failure was the most common complication in all regions Table 6.
In general, the highest complication rates occurred in North America and Europe. There were also geographic differences in treatment and outcome, although the magnitude of this variation was not large Table 6. Surgical treatment was common for the entire cohort Table 7 shows the results of the regression modeling for in-hospital mortality with the estimates from bootstrap validation.
The following variables were independently associated with an increased risk of in-hospital death: involvement of a prosthetic valve, increasing age, radiographic pulmonary edema, S aureus infection, coagulase-negative staphylococcus infection, presence of mitral valve vegetation, and paravalvular complications.
Variables independently associated with a decreased risk of in-hospital death were elevated erythrocyte sedimentation rate ESR , infection with a viridans group streptococcus, and surgery during the current IE episode.
The estimates obtained by bootstrap validation were similar to those of the original model and support the validity of this model. Differences between models were noted for the following 4 variables: diabetes mellitus, health care—associated acquisition, coagulase-negative staphylococcus infection, and presence of a mitral valve vegetation. Of the total cohort of patients with definite IE, Analysis of the data after excluding these patients revealed few differences from analysis of the whole cohort Tables 2 , 4 , and 6.
Notable differences were that transferred patients were more likely to undergo surgery Despite more than a century of study and recent advances in diagnosis and treatment, IE remains an incompletely understood disease with high morbidity and mortality. Textbook descriptions of the clinical features and epidemiology of IE are still largely based on data obtained several decades ago. Lack of progress is partly related to the fundamental difficulty in studying this type of disease.
By necessity, most studies are derived from case reports or small case series from single sites, with few large cohort studies or randomized trials. A shift in approach is necessary to further the understanding of endocarditis and to definitively study therapeutic choices.
To our knowledge, this study is by far the largest prospective cohort study of IE to date. The size of the cohort coupled with the multinational perspective has enabled several important observations to be made. Our findings reveal that, in much of the world, IE is no longer a subacute or chronic disease occurring primarily in younger patients with rheumatic valvular abnormalities. In contrast, most patients in this investigation presented early and demonstrated few of the classic clinical findings traditionally associated with IE.
Prosthetic valve endocarditis was present in one-fifth of our patients, as discussed in detail elsewhere. An emerging population at risk for IE consists of patients with health care—associated infections. These findings confirm those of recent reports from small single-center studies 16 , 28 and provide evidence that these population changes are occurring in many regions of the world.
The health care setting will continue to gain importance in relation to complications such as IE, mainly owing to aging societies that rely on increasingly invasive medical care. Our analysis has provided evidence of geographic differences for several important characteristics in patients with IE. For example, although the overall IE population characteristics were influenced by contact with health care services and medical interventions, this specific finding was not observed in the centers from South America.
Two were female. The commonest presenting symptoms were nocturnal sweating with or without severe coughing attacks, symptoms of cardiovascular disease, anorexia and weight loss, neurological and gastrointestinal symptoms and itching with or without skin lesions. The mean blood eosinophil counts at presentation were Eight patients had previous allergic or parasitic disease which could have predisposed them to the development of hypereosinophilia.
