Global Landscape of Infection-Induced Pulmonary Hypertension

Area of Science:

• Infectious Diseases
• Pulmonary Medicine
• Global Health

Background:

• Infectious diseases, especially parasitic infections, are significant contributors to pulmonary vascular disorders.
• Pulmonary hypertension (PH) is a serious complication, particularly prevalent in developing nations.
• Parasitic lung diseases are an underrecognized cause of PH in endemic areas.

Purpose of the Study:

• To review the prevalence of parasitic lung diseases and their link to PH.
• To examine global epidemiological trends and diagnostic challenges of infection-related PH.
• To highlight recent advancements in understanding the origins of PH.

Main Methods:

• Literature review of parasitic infections and pulmonary hypertension.
• Analysis of epidemiological data from endemic regions.
• Synthesis of current research on pathophysiological mechanisms.

Main Results:

• Schistosomiasis and HIV are key drivers of PH in endemic regions.
• Other infectious agents also contribute to pulmonary vascular lesions but require further study.
• A strong association exists between parasitic infections and the development of PH.

Conclusions:

• Pulmonary hypertension should be suspected in patients with parasitic disease history, especially in endemic zones.
• Further research is essential to elucidate infection-related PH mechanisms.
• Interventions are needed to mitigate the global impact of PH caused by infections.
