Long COVID Management

Introduction to Long COVID

Long COVID is a diagnosis of exclusion that requires ruling out other serious conditions, with management focusing on symptom-based supportive care including energy conservation strategies and careful activity pacing, according to the Clinical Microbiology and Infection guidelines 1

A comprehensive diagnostic workup to rule out other serious conditions is essential before attributing symptoms to long COVID, with tests including complete blood count with differential, C-reactive protein, kidney and liver function tests, and thyroid function tests 1
If respiratory symptoms are present, consider pulmonary function testing, and if cardiac symptoms are present, consider troponin, CPK-MB, and B-type natriuretic peptide 1

Implement careful activity pacing to avoid post-exertional malaise (PEM), and structure daily activities within the patient's energy envelope 1
Validate the patient's experience of fatigue, and consider psychosocial factors that may worsen fatigue, such as lack of social support, high neuroticism, low resilience, and previous threatening experiences 1
Regular monitoring of blood counts to track leukopenia and monocytosis is necessary, as persistent laboratory abnormalities may occur after COVID-19 and should be interpreted with caution 1
Evidence is insufficient to recommend specific medications for long COVID fatigue, and medications that might worsen neutropenia should be avoided 1
For patients with hematological abnormalities resembling myelodysplastic syndrome features, a watch-and-wait approach for modest cytopenias, and erythropoiesis-stimulating agents if anemia develops, are recommended by The Lancet Haematology 2

If blood abnormalities worsen or persist beyond 6 months, consider hematology consultation, and for patients with features of myeloproliferative disorders and mild-to-moderate leukocytosis, a watch-and-wait approach is recommended by The Lancet Haematology 2
Consider referral to a specialized long COVID clinic if available, for holistic management and monitoring of symptoms and blood counts 1

Regular follow-up every 4-6 weeks initially to monitor symptoms and blood counts, and adjust management based on symptom progression and laboratory findings, is necessary for effective long COVID management 1
