“Lupus is a disease of a thousand faces”—and some of its most difficult symptoms are the ones clinicians cannot see."

In this episode, hosts Dr. Daniel Ennis and Dr. Janet Pope are joined by Dr. Zahi Touma to explore cognitive neuropsychiatric symptoms in patients with systemic lupus erythematosus (SLE). They examine the difference between patient-reported “brain fog” and objectively measured cognitive impairment, the cognitive domains most commonly affected, and why symptoms can be so difficult to attribute to the disease itself.

Dr. Touma discusses what long-term research reveals about cognitive trajectories in patients with SLE, including why some patients remain stable, some experience persistent impairment, and others fluctuate over time. The conversation also considers the influence of depression, chronic pain, and sleep disorders; the limitations of current blood tests and brain imaging; and emerging research into functional imaging; and potential biomarkers such as calprotectin.

Most pertinently, the episode asks what rheumatologists can do now. While better screening tools and targeted treatments are still being developed, the first step is listening to patients, taking their cognitive concerns seriously, and offering appropriate reassurance that impairment does not necessarily mean continued decline.

Dr. Zahi Touma is an Associate Professor of Medicine and Clinician-Scientist with the University of Toronto, the Krembil Research Institute, and Schroeder Arthritis Institute. He is also the director of the Lupus Program at Toronto’s University Health Network (UHN). His research is focused on patients with systemic lupus and also measurement science, with a particular interest in the assessment of disease activity, patient-reported outcomes, and cognitive function.

Dr. Daniel Ennis is a rheumatologist and clinical faculty member in the Division of Rheumatology at the University of British Columbia.

Dr. Janet Pope is a professor of medicine at Western University and division head of rheumatology at St. Joseph’s Health Care London. Her research focuses on systemic sclerosis, lupus and rheumatoid arthritis.

Turning 18 doesn’t mean that a young person is suddenly ready to manage a lifelong illness alone. Between 25 and 75 percent of young people with rheumatic diseases experience a gap in care or are lost to follow-up after moving into the adult system — even though most will require ongoing treatment and monitoring.

Join pediatric rheumatologist Dr. Michelle Batthish as she chats with our hosts Dr. Janet Pope and Dr. Daniel Ennis about why transition should be a gradual process rather than a single transfer of care.

They explore how clinicians can assess readiness, help patients become more independent with appointments and medications, and support parents as their role changes. They also discuss young-adult rheumatology (YARD) clinics, the reasons patients are lost to follow-up, and the importance of addressing mental health, relationships, and the other pressures facing young adults.

Dr. Michelle Batthish is a pediatric rheumatologist at McMaster Children’s Hospital and associate professor of pediatrics at McMaster University. She is a CanChild scientist and chairs the Canadian Rheumatology Association’s Transition Working Group. Her research focuses on healthcare transition and quality improvement in pediatric rheumatology.

In this episode of Around the Rheum, hosts Dr. Daniel Ennis and Dr. Janet Pope sit down with Dr. Luke Chen for a deep dive into an approach to patients presenting with hypereosinophilia. Recorded at the Canadian Rheumatology Association (CRA)’s 2026 Annual Scientific Meeting in Halifax, the conversation explores how hematologists, rheumatologists, allergists, infectious disease specialists, and others work together to diagnose and manage these complex disorders.

Dr. Chen discusses the broad differential diagnosis behind eosinophilia — from Eosinophilic Granulomatosus with Polyangiitis (EGPA) and IgG4-related disease to parasitic infections to rare hematologic disorders to 'Idiopathic' Hypereosinophilic Syndrome (I-HES) — and the uncertainty clinicians often face when distinguishing overlapping eosinophilic diseases. The discussion also highlights emerging therapies including IL-5 inhibitors, JAK inhibitors, interferon, and biologics, alongside the practical realities of access to treatment in rare disease care.

Thoughtful, practical, and candid, this episode offers insight into multidisciplinary medicine, diagnostic humility, and caring for patients living with rare inflammatory diseases. It touches on the importance of being okay with uncertainty in the rare disease space.

Dr. Luke Chen is a hematologist and Professor of Medicine at Dalhousie University in Halifax, Nova Scotia. His clinical and research interests focus on rare inflammatory diseases and eosinophilic disorders. He is the founder of the Coastal Rare Inflammatory Diseases Program, supporting physicians caring for patients with rare diseases across Canada.
