Shovlin CL, Bamford KB, Wray D, 2008, Post-NICE 2008: Antibiotic prophylaxis prior to dental procedures for patients with pulmonary arteriovenous malformations (PAVMs) and hereditary haemorrhagic telangiectasia, British Dental Journal, Vol: 205, Pages: 531-533

Recently published guidance from NICE highlights that antibiotic prophylaxis is no longer required for patients with structural heart disease at risk of infective endocarditis. The American Heart Association has published similarly less interventive guidance. Individuals with pulmonary arteriovenous malformations and hereditary haemorrhagic telangiectasia are at risk of brain abscess from dental bacteraemias. In this article we explore why these patients do not fall into the groups considered by NICE and provide recommendations to reduce their risks of dental bacteraemias, including optimising dental hygiene and use of antibiotic prophylaxis prior to dental procedures.

Introduction: Hereditary haemorrhagic telangiectasia (HHT) causes chronic nasal and gastrointestinal haemorrhage. Prothrombotic agents are commonly used for severe haemorrhage. Thrombotic risks have not been defined. Methods To identify prothrombotic variables in HHT patients, and assess their potential functional significance, a pilot ELISA-based study comparing plasma proteins in healthy individuals with HHT to age/sex-matched non-HHT controls was validated in a full study of 309 consecutive HHT-affected individuals. Results In the pilot study, Factor VIII (FVIII) and Von Willebrand Factor antigen concentrations were elevated in the HHT group compared to non-HHT controls (p0.0013, Mann-Whitney). Service laboratory measurements confirmed high FVIII:Ag in 125 HHT-affected individuals with no recent ill-health, intervention or venous thromboemboli. FVIII:Ag levels increased with age. Logistic regression also suggested an age-independent association with HHT-associated pulmonary arteriovenous malformations (PAVMs). No association was demonstrated between FVIII:Ag and acute phase response, disseminated intravascular coagulation, ABO group, pulmonary artery pressure, or markers of HHT haemorrhage. Elevated FVIII:Ag were associated with shortened activated partial thromboplastin times (APTTs), and VTE: VTE affected 20/309 (6.5%) HHT-affected individuals, at median age 61(36-71)yr. Four VTE occurred in Factor V Leiden heterozygotes in the months following PAVM-associated brain abscess. The strongest association with VTE was with log-transformed FVIII:Ag measured 10-132 months from VTE (odds ratio 2.41 (95% confidence intervals 1.254, 4.612, p=0.008). Age made no additional contribution to VTE risk once adjusted for FVIII:Ag. Conclusions HHT-related elevation of FVIII:Ag levels may influence thrombotic risk in HHT. Individualised risk-benefit considerations may be helpful in the management of individuals with HHT.

Hepatopulmonary syndrome (HPS) may cause profound symptomatic hypoxia in patients with chronic liver disease and can be an indication for liver transplantation. The diagnosis relies on the demonstration of intrapulmonary vascular dilatation (IVD) using either contrast-enhanced echocardiography or macro-aggregated lung perfusion scans. We sought to evaluate whether a novel technique using the microbubble agent, Echovist® (Schering AG) with Doppler intensitometry of the carotid artery would be able to identify patients who fulfilled the criteria for HPS. Contrast studies were performed in 18 patients with cirrhosis, examined in the supine and upright positions. Following injection of Echovist, continuous scanning of the common carotid was performed using grey-scale and spectral Doppler for 60 s. Positive studies were determined by online signal analysis of the Doppler signal (crackle-count). Supine and upright pulse oximetry was recorded on all patients, and formal lung function tests where clinically indicated. Two patients met the criteria for HPS. They had positive results on supine and upright scans, with an increased crackle-count when upright. Two patients had single, weakly positive results with normal pulse oximetry. No association was seen between a positive contrast study and the severity of liver disease. Contrast-enhanced carotid Doppler intensitometry is a relatively simple, non-invasive test that may help identify patients with IVD. Comparison with an established technique will be required in future trials to determine its accuracy and assess whether the crackle-count can reliably quantify the degree of IVD. © 2005, Maney Publishing.

1. This manuscript describes two different strategies to progress from the clinical assessment of patients to the identification of disease-causing mutations. In the first disease, recognition of a metabolic abnormality allowed direct molecular analysis of the causal gene. In contrast, localization of the second disease gene by linkage analysis was critical to implicate a gene with a previously unsuspected disease role. 2. Two sisters with chronic respiratory disease and recurrent infections were identified as the first cases of adult onset immunodeficiency due to adenosine deaminase deficiency. Autosomal recessive inheritance of two mutations in the adenosine deaminase gene was demonstrated. Enzyme replacement therapy improved the patients' immunological and clinical status. 3. Individuals with pulmonary arteriovenous malformations were used to identify families with hereditary haemorrhagic telangiectasia (HHT, Rendu-Osler-Weber Syndrome). Linkage studies mapped the HHT disease gene in some families to chromosome 9, and demonstrated genetic heterogeneity. The chromosome 9 disease interval was refined, and several candidate genes were assessed. Following the first description of disease-segregating mutations, a complete analysis of the endoglin gene (which encodes an endothelial cell transforming growth factor-beta receptor) identified seven novel mutations. Two mutations did not produce mutant mRNA, and disease severity was comparable between families, indicating that HHT results from stoichiometric insufficiency of endoglin. 4. Each study has implications extending beyond the relatively rare disease analysed. The adenosine-deaminase-deficient patients highlight a treatable cause of HIV-negative CD4+ lymphopenia in adults, perhaps accounting for further cases of 'non-HIV AIDS'. The HHT studies have illuminated a novel area of vascular pathophysiology, with potential relevance to further disease states.
