Schistosomiasis-associated pulmonary hypertension.

Schistosomiasis, a parasite-borne disease, is highly prevalent in Africa and Asia; it is estimated that close to 20 million people worldwide have a severe form of the disease. The chronic form can affect the gastrointestinal system and lead to hepatosplenic disease, and it may cause cardiopulmonary complications, including pulmonary hypertension. The exact pathogenesis of schistosomiasis-associated pulmonary hypertension (Sch-PH) remains unclear, although several mechanisms, including parasitic arterial embolization, pulmonary arteriopathy, and portopulmonary hypertension-like pathophysiology, have been suggested.

Republished: recent advances in the epidemiology, diagnosis and treatment of endomyocardial fibrosis in Africa.

Endomyocardial fibrosis (EMF) continues to be an important and disabling disease in many parts of Africa, although its prevalence has declined in some parts of the continent. Increased access to medical care in general and increased availability of echocardiography in some parts of the continent have led to recognition of the disease in areas in which the disease had not been previously reported, and this has given new insights into its natural history. However, the early manifestations of EMF continue to elude clinicians and researchers, and no progress has been made in defining its aetiology.

Right ventricular endomyocardial fibrosis.

Endomyocardial fibrosis (EMF) is a neglected tropical cardiomyopathy of unknown etiology and pathogenesis that is common in certain tropical areas of Africa, Asia, and South America. It affects predominantly children and young adults. Endocardial fibrosis is the hallmark of this restrictive cardiomyopathy leading to restriction to diastolic filling of the ventricles with severe atrial dilatation.
