No full textSchistosomiasis is the most common parasitic disease associated with pulmonary arterial hypertension (PAH). It induces remodeling via complex inflammatory processes produced by the parasite eggs. Changes in the pulmonary vasculature after Schistosoma infection are common, but may not always be associated with a clinical manifestation of PAH. Those patients who presented with PAH show clinical signs and symptoms that are not distinguishable from other forms of PAH.</jats:p
Saudi Guidelines on the Diagnosis and Treatment of Pulmonary Hypertension: Schistosomiasis and pulmonary arterial hypertension
No full textSchistosomiasis is caused by infection with the parasite Schistosoma, which is a flat-worm or fluke. The dominant species are Schistosoma mansoni, Schistosoma japonicum, and Schistosoma haematobium. Schistosomiasis is the third most common parasitic disease in the world after malaria and amoebiasis. It is endemic in more than 70 countries affecting about 200 million people worldwide, of whom 80% are in sub-Saharan Africa. There are pockets of infection in north-eastern Brazil, near the Yangtze River in China, and some pockets in south East Asia. In the East Mediterranean regions, the Schistosoma have been reported in Iraq and Egypt as well as in Sudan. The latter has the highest infection rate nowadays, particularly in the Al Jazeera area, due to the poor Schistosoma control program. In the Arabian peninsula, schistosomiasis has been reported in southwest part of Saudi Arabia, mainly in the Asir province and Jizan province, which lay in the southwest corner of Saudi Arabia and directly north of the border with Yemen. The efforts to control schistosomiasis have been very successful in Saudi Arabia due to the irrigation system control. However, the infection is prone in Yemen, where the schistosomiasis control is much less strict. Thus as a result, the problem still exists due to transmigration of the populations from both countries.
As a cause of pulmonary arterial hypertension (PAH), schistosomiasis is still under diagnosed and undertreated. This article with give a highlight about the pathophysiology of the disease and both diagnostic and therapeutic strategies
Global Landscape of Infection-Induced Pulmonary Hypertension
Get PDFIntroduction: Infectious diseases significantly impact pulmonary vascular disorders, particularly in developing countries where parasitic infections remain prevalent. These infections constitute a substantial yet frequently overlooked contributor to pulmonary hypertension. Discussion: This review examines the prevalence of parasitic lung diseases in regions where communicable infections are endemic and highlights their pathophysiological links to pulmonary hypertension. Schistosomiasis and HIV notably increase pulmonary hypertension risk in these areas. While other infectious diseases may also cause pulmonary vascular lesions, most remain insufficiently studied. The review addresses global epidemiological trends, diagnostic challenges, and recent advancements in understanding the multifaceted origins of pulmonary hypertension. Conclusion: The association between parasitic infections and pulmonary hypertension is significant, necessitating a high index of suspicion for pulmonary hypertension in patients with a history of parasitic diseases, especially in endemic regions. More research is needed to understand infection-related pulmonary hypertension mechanisms and reduce its global impact
