Not too long ago, there were doubts about the validity of long COVID, with some dismissing it as a psychosomatic illness. Fortunately, we can now put those speculations to rest, as compelling evidence confirms that long COVID is indeed a real condition that can affect major organs. A study conducted on a sample of 259 individuals previously hospitalized with COVID compared to a control group of 52 non-infected individuals revealed astonishing results. MRI scans showed that those with long COVID were 14 times more likely to have lung abnormalities, three times more likely to have brain abnormalities, and two times more likely to have kidney abnormalities compared to those who had never contracted the disease. The severity and extent of these abnormalities were correlated with the individual’s age, the severity of their COVID infection, and the presence of other underlying diseases. Furthermore, those with long COVID affecting more than two organs were at a significantly higher risk of experiencing severe mental and physical impairment.

A Complex Disease

Initially, COVID-19 was primarily identified as a respiratory illness, with typical symptoms such as coughing, shortness of breath, and pneumonia-like signs. However, as our understanding of the disease evolved, so did our knowledge of its complexity. Reports emerged of the virus not only affecting the lungs but also targeting other vital organs, including the heart, kidneys, brain, and blood vessels. Research demonstrated the presence of viral proteins in various organs, indicating the virus’s affinity for tissues beyond the respiratory system. The prevailing theory initially suggested that SARS-CoV-2 directly infected cells across multiple organs. Yet, as more data accumulated, a more nuanced understanding emerged. In some cases, the immune system’s response to the virus led to a phenomenon known as a “cytokine storm,” where the immune system’s overactivation resulted in unintended damage to organs not directly under viral attack. Additionally, reports highlighted the virus’s tendency to induce excess clotting, disrupt mitochondria (the powerhouses of our cells), and reactivate other viruses. These findings necessitated a shift in the narrative surrounding COVID-19, acknowledging it as a multisystemic disease with the potential for long-term complications, challenging our conventional approach to treatment.

In the United Kingdom, efforts were made to shed light on the long-term effects of COVID-19 through the C-More study, focusing on patients who had been previously hospitalized. This study stands out from its predecessors as it examines the harm inflicted on multiple organs within the same individual. However, like any pioneering study, there are limitations to consider. The latest results, mentioned above, are based on preliminary data from only half of the study population, meaning a complete analysis is still pending. Additionally, the lack of pre-COVID MRI scans from patients makes it challenging to draw definitive conclusions regarding the link between COVID-19 and organ changes. While the control group participants were not an exact match to the patient population, efforts were made to adjust analyses to account for any discrepancies, ensuring the accuracy of the findings. It is also worth noting that the MRI scans may not have always provided a complete explanation for the symptoms experienced by individuals in specific organs. For instance, even if the scans showed normal organ function, patients could still exhibit related symptoms. Despite these limitations, the C-More study represents a significant endeavor to enhance our understanding of the long-term impact of COVID-19 on organ health. It serves as a reminder to remain vigilant about the potential long-term consequences of the disease and the crucial role of vaccination, especially for those at higher risk of severe infections.

The findings from the C-More study emphasize the urgent need to address long COVID as a serious condition that extends beyond acute respiratory symptoms. It highlights the importance of recognizing the potential impact on multiple organs and the substantial burden it can impose on individuals’ mental and physical well-being. To mitigate the long-term consequences of COVID-19, healthcare professionals and policymakers must prioritize targeted research, comprehensive healthcare support, and widespread vaccination efforts. Awareness campaigns directed at healthcare providers and the general public can aid in early detection and appropriate management of long COVID symptoms. By embracing a multidisciplinary approach, including vital organ monitoring and tailored treatment plans, we can navigate the complexities of this evolving disease more effectively and promote better outcomes for those affected.

Our understanding of long COVID has come a long way since the early days of speculation. We now have concrete evidence of the impact on major organs, solidifying its existence as a genuine and complex condition. The pioneering C-More study provides crucial insights into the long-term consequences of COVID-19, necessitating a shift in our approach to diagnosis, treatment, and prevention. It is our collective responsibility to recognize the reality of long COVID, advocate for greater awareness and support, and work towards comprehensive solutions that prioritize the health and well-being of all individuals affected by this lingering aftermath of the pandemic.
