2021 Annual Report

The Infection in Pulmonary Vascular Disease (iPVD) Task Force continued to meet over the past year to plan two major projects.

These are:

  • The 3rd Annual iPVD meeting to take place in Athens in 2022.
  • The drafting of three translational reviews on the topic of COVID-19 and cardiopulmonary sciences. 

We are excited to have finalised the agenda for our annual meeting which will tackle relevant topics such as the current knowledge of cardiopulmonary sequelae of COVID-19 and cutting-edge research on HIV and Schistosoma-associated PAH.

Dr Catherine Blish from Stanford University has been invited to give a special keynote lecture during this meeting, entitled: COVID-19 Current Knowledge and Epidemiology. She has led international efforts to study SARS-COVID to give a state-of-the-art presentation that will guide our discussion on this topic.

2020 Annual report

The infection and pulmonary vascular disease Task Force was established in 2019 by combining the Schistosomiasis Task Force and HIV Task Force, the legacy Task Forces since the foundation of the PVRI in 2006. It was a natural development to enhance and consolidate the interest in the infection as one of the major causes of pulmonary vascular disease globally. It also consolidated the work with the IPVD (Infection and pulmonary vascular disease) Consortium which was established in 2017 to promote awareness and research collaboration on the role of infection in the pathobiology of pulmonary vascular disease.

There have been several activities which can be summarised as follows during the fourth quarter of 2019 and in 2020. The 1st International Conference on the Infection and Pulmonary Vascular Disease was organised in Aswan on 21-22 October 2019 in collaboration with the Magdi Yacoub Foundation. The two day meeting discussed the role of various infections on pulmonary vascular disease, including inflammation and immunology of pulmonary arterial hypertension, HIV and Schistosomiasis co-infection with pulmonary vascular diseases, and epidemiology of Schistosomiasis, HIV and Tuberculosis in Africa. There was a discussion of the future working plan on the role of Tuberculosis and collecting clinical data in Africa and globally.

The 2nd International Conference on the Infection and Pulmonary Vascular Disease was organised in Lima on 29 January 2020, as a pre-conference of the 14th PVRI Annual World Congress on Pulmonary Vascular Disease. The aim was to follow up on the outcomes of the first symposium in Aswan, Egypt, and update on the new findings and techniques in the area of inflammation, infection and pulmonary vascular diseases. This included panel discussions on Schistosomiasis and PVD, update on the emerging data on HIV- Schistosomiasis co-infection in PVD and the potential role of microbiota in pulmonary vascular diseases.

The Task Force in collaboration with IPVD Consortium and the Pulmonary Circulation working group of the American Heart Association organised a special session on the global aspects of PVD and infections at the annual meeting of American Heart Association in Philadelphia 2019.

Another session was planned on the role of double-hit hypothesis on PVD during the Annual American Thoracic Society May 14-19 2020, but this was cancelled because of Covid-19 pandemic and reorganisation of the ATS meeting to a small virtual meeting.

The Task Force and the IPVD consortium also organised ‘On Demand Sessions’ during the American Heart Association annual meeting in 16–18 November 2020. The session entitled “Environmental Risk Factors for Pulmonary Hypertension” was broadcasted live on 18 November 2020.

2020. Drs Ana Mocumbi, Anubha Agarwal, and Vinicio de Jesus Perez shared their data and viewpoints.

The high impact journal Nature Reviews has commissioned the PVRI Task Force and IPVD to write a comprehensive review article on the role of Covid-19 on a potential complication of the pathobiology of pulmonary vasculature. A select writing group is currently working on this review (and other articles) for possible publication in mid-2021.

The plan for The 3rd International Conference on the Infection and Pulmonary Vascular Disease is on hold now because of the uncertainty of Covid-19 pandemic. However, the group is currently in continuous communication among its member through various zoom meetings.

2019 Annual report

HIV Task Force Merger

The Pulmonary Vascular Research Institute’s HIV Task Force – headed up by Navneet Dhillon and Nicola Petrosillo – has now been subsumed under the Infection & Pulmonary Hypertension umbrella.

This has in no way affected their focus on pulmonary manifestations of HIV, but has allowed for the team to increase the scale of their work. You can visit the HIV Task Forcepage here.

1st International Symposium on Infection and Pulmonary Vascular Diseases – Aswan, Egypt (21-22 October 2019)

The first International Symposium on Infection and Pulmonary Vascular Diseases and meeting of the iPVD consortium1 took place in Aswan, Egypt from 21-22 October 2019.

-        The aim of this meeting was to discuss the emerging issues of the role of infection of the pulmonary vasculature with pulmonary vascular disease specialists, cardiologists; pulmonologists and immunologists; epidemiologists, parasitologists, as well as other infectious disease specialists. 

-        The meeting format was that of a conversation between pulmonary vascular disease experts and attendees. It was divided into six seminars2.  This started with a welcome talk from Professor Sir Magdi Yacoub, followed by an introductory talk from Professor and founding PVRI member, Ghazwan Butrous


iPVD Seminars

Day 1

  1. The first seminar was chaired by Professor Stephen Chan, USA, and Dr Ahmed Al Guindy, UK. Discussants were Dr Rajkumar Savai, Germany, and Dr Matthias Clauss, USA, with a special remote presentation given by Dr Soni Savai-Pullamsetti, Germany. They discussed the role of inflammation and immunology on pulmonary arterial hypertension and with infection in particular.
