Who we are

The Division of Pulmonary Medicine can provide you and your child with information, support and advanced treatment options for your child’s breathing challenges. We offer inpatient and outpatient services for infants and children with both short-term and chronic respiratory problems. 

While the inpatient Respiratory Medicine is primarily a consulting service, our outpatient service is the division’s main responsibility. In addition, Respiratory Medicine follows patients in hospital requiring complex respiratory care, such as home ventilation, as well as patients with cystic fibrosis and rare respiratory illnesses such as interstitial lung disease. 

Research activities

Some of the major research going on in the Division of Respiratory Medicine is the CHILD Study, led by Dr. Padmaja Subbarao.

Expand each section below to learn more about what our esteemed staff are researching. 

Most recently the CHILD Study was awarded $1.7M to study impacts of COVID-19 on Canadian families

$1.7 million award from the Canadian Institutes of Health Research (CIHR) and Research Manitoba will allow CHILD researchers to study how individuals and families across Canada have been impacted directly by COVID-19 infections, and indirectly by pandemic-related social and economic upheaval. 

DrReshma Amin (nominated PI) received funding (CIHR, Muscular Dystrophy Canada, Boehringer Ingelheim, ProRespMedigas, VHA Home Healthcare) for four years in July 2019 to complete a multi-site clinical trial titled, A Virtual Transition Intervention for Children and Adults Transitioning to Home Ventilation in Ontario: A Pragmatic Randomized Controlled Trial. The trial will evaluate the impact of a multi-component virtual care solution that overcomes distance and time by bringing the “Right People with the Right Expertise at the Right Time” into the home to improve quality of life, reduce family caregiver burden, and prevent unnecessary hospital admissions.

A 12 month, seven-centre, randomized controlled trial with individuals (children and adults) newly transitioning to home ventilation was planned to launch in July 2020. COVID-19 presented an unprecedented need to implement this virtual care platform to all 5,000 individuals using Home Ventilation in Ontario immediately. Funding was secured for a COVID-19 clinical implementation of this virtual care solution and Dr. Reshma Amin and Regina Pizzutimanager of the Ontario Ventilator Equipment Pool (VEP), are the co-directors of this clinical program.  

The team was ready to deploy the virtual care solution because of the research trial groundwork and is positioned to scale to all individuals (children and adults) in Ontario using home mechanical ventilation to support ‘care at home.’ The virtual care platform enables 1) text, phone and videoconference calls; 2) a virtual care plan that is co-developed by the family and the healthcare team; 3) weekly and monthly questionnaires about symptoms and ventilator use to identify issues early; and 4) remote ventilator data downloads for ongoing monitoring of patients at the ease of a button in between clinic visits.  

SickKids is the first hospital to onboard patients with 25 patients enrolled already. The following hospitals are also participating with a plan to launch at their sites shortly: Sunnybrook, London Health Sciences, Ottawa Hospital, West Park, McMaster Children’s Hospital, Children’s Hospital of Eastern Ontario. This was a provincial virtual care strategy for children and adults using Long-term Home Mechanical Ventilation during COVID-19 but this virtual care platform will ideally be sustainable beyond the pandemic and facilitate ongoing care. 

Dr. Felix Ratjen led the Lancet Commission on the global perspective of future care for cystic fibrosis. Decades of progress in the care of people with cystic fibrosis mean that patients are living longer, healthier lives than ever before. However, the disease continues to limit survival and quality of life in high-income countries, and many patients in low-income and middle-income countries do not have access to integrated multidisciplinary care or affordable therapies.  

With a growing population of adult patients, widespread genetic testing for the diagnosis of cystic fibrosis, increased recognition of patient populations of non-European descent, and the development of potentially life-changing therapies that target the underlying cause of cystic fibrosis, an unprecedented opportunity exists for improved health outcomes. Bringing together 30 leaders in the field from all continents, The Lancet Respiratory Medicine Commission, led by Scott Bell and Felix Ratjen, reviewed the latest research advances and identified challenges and opportunities for progress in the care of patients globally. 

L-Arginine / Nitric Oxide Metabolism in Asthma  

One of Dr. Grasemann’s research interests is the role of the L-arginine/Nitric Oxide metabolism for asthma. The Grasemann lab had previously demonstrated in animals and preclinical studies that alterations in the L-arginine metabolism such as increased arginase activity and asymmetric dimethylarginine (ADMA) contribute to reduced Nitric Oxide availability in asthma.  

He is currently pursuing this in two Research Project Grants (R01) by the National Institutes of Health - National Heart, Lung, and Blood Institute (NIH-NHLBI), of which one is a longitudinal lifestyle modification study aiming to unveil metabolic and behavioral pathways in asthma and the other is a randomized controlled clinical trial on the effects of L-citrulline supplementation on pulmonary function and asthma control in obese asthmatics.
