Tricuspid valve endocarditis associated with intravenous nyoape use: A report of 3 cases

We report three cases of tricuspid valve infective endocarditis associated with intravenous nyoape use. Nyoape is a variable drug combination of an antiretroviral (efavirenz or ritonavir), heroin, metamphetamines and cannabis. Its use is becoming increasingly common among poor communities in South Africa. All our patients were young HIV-positive men from disadvantaged backgrounds. They all presented with tricuspid regurgitation and septic pulmonary emboli. They were treated with prolonged intravenous antibiotic courses, and one required referral for surgery

Management of pulmonary hypertension

Pulmonary arterial hypertension (PAH) is a potentially lethal disease mainly affecting young females. Although the precise mechanism of PAH is unknown, the past decade has seen the advent of many new classes of drugs with improvement in the overall prognosis of the disease. Unfortunately the therapeutic options for PAH in South Africa are severely limited. The Working Group on PAH is a joint effort by the South African Heart Association and the South African Thoracic Society tasked with improving the recognition and management of patients with PAH. This article provides a brief summary of the disease and the recommendations of the first meeting of the Working Group

Prevention of infective endocarditis associated with dental interventions : South African Heart association position statement, endorsed by the South African Dental Association

CITATION: Jankelow, D., et al. 2017. Prevention of infective endocarditis associated with dental interventions : South African Heart association position statement, endorsed by the South African Dental Association. SA Heart, 14(3):170-174, doi:10.24170/14-3-2716.The original publication is available at http://www.journals.ac.za/index.php/SAHJENGLISH ABSTRACT: Infective endocarditis (IE) is associated with significant morbidity and mortality. Prevention is therefore an important clinical entity. The maintenance of optimal oral health is likely to play the most important role in protecting those at risk for IE. Both patients and health care practitioners must be educated in this regard. Guidelines have recommended that antibiotic prophylaxis should be limited to individuals (undergoing certain high-risk dental procedures) with underlying cardiac conditions that are associated with the greatest risk of an adverse outcome from IE. These conditions include prosthetic valves, congenital heart disease and previous IE. In South Africa, and other developing countries, IE is often a disease of young patients with rheumatic heart disease (RHD) and carries a very poor prognosis. In contrast, IE in Europe/North America, where guidelines and indications for antibiotic prophylaxis have been reduced, has a different spectrum of factors. These patients are older with degenerative valve disease. IE may also occur as a result of invasive health care associated procedures or in the setting of prosthetic valves and implantable cardiac devices. Recently published international guidelines cannot be automatically applied to countries where RHD is common and oral hygiene is poor. We therefore recommend that patients with RHD should also receive antibiotic prophylaxis prior to the listed dental procedures. Antibiotic prophylaxis should be prescribed after stressing the role of good oral health and why the approach differs in South Africa. There should be close cooperation between the dental practitioner and clinician as to who should receive prophylaxis and who should not.http://www.journals.ac.za/index.php/SAHJ/article/view/2716Publisher's versio
