BACKGROUND: Heat shock proteins (HSPs) are involved in innate and adaptive immune responses, especially inflammatory responses due to immune cell activation. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was one of the most important causes of death in the recent pandemic. Increased cellular stress and excessive inflammation are common in coronavirus disease-19 (COVID-19), although the underlying mechanisms are still poorly understood.
OBJECTIVE: To evaluate the relationship between HSP and the pathological effects of COVID-19.
METHODS: A group of 107 patients was categorized to two populations (mild and severe) based on their chest high-resolution computed tomography (HRCT) results. The HSP70, HSP90 alpha, and serum levels of C-reactive protein (CRP) were measured by enzyme-linked immunosorbent assay (ELISA). Lactate dehydrogenase (LDH), and creatine phosphokinase (CPK) were measured by the automated analyzer.
RESULTS: Our data showed increased levels of HSP70 and HSP90 in patients with COVID-19. The HSPs levels were elevated in the severe group compared to the mild group. This study demonstrated a positive correlation between both elevated levels of HSP70, HSP90, and HRCT grade and also a positive correlation with CRP and CPK in the severe group.
CONCLUSION: HSP90 and HSP70 contribute to excessive immune responses and cytokine storms. They may serve as prognostic serum markers for COVID-19 lung injury. Additionally, they are candidates for anti-inflammatory therapy.
