ABSTRACT
We previously proposed the term "opportunistic non-communicable diseases (NCDs)" to raise awareness of how NCDs thrive in societies with inadequate healthcare services. However, we did not anticipate that within the next year the new corona virus disease (COVID-19) would sweep the globe. Lockdowns became the primary strategy for mitigation in most countries. However, the extensive restrictions and allocation of resources towards the containment of the pandemic has likely served as a catalyst of NCDs, especially in populations, societies, and individuals already at high risk. We are presenting evidence to qualify two primary factors responsible for the potential impact on the development of NCDs during the COVID-19 pandemic. The first is disrupted healthcare services including avoidance and postponement of health care visits. The second is effects of changing lifestyle and living conditions including isolation, loss of job and income. The accumulated effect of these factors will likely further accelerate the development of NCDs and impair their management, especially in low- and middle-income countries. Insufficient vaccination coverage due to inequality in vaccine distribution and vaccine hesitancy left room for the incubation of immune-evasive variants that threatened to sustain or reinitiate the pandemic. We believe the concept of opportunistic NCDs and the potential catalytic effect that pandemics may have on the development of NCDs and their management, should be used as further arguments to secure equal vaccine distribution, promote global vaccine acceptance and to speed up and increase investments in primary health care in low and middle-income countries to cope with the already existing NCD crisis and to prepare for future epidemics.
ABSTRACT
RATIONALE: This case report demonstrates the use of flourine-18 fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/computed tomography (CT) to rule out Richter transformation (RT) as the cause of clinical deterioration in a patient with chronic lymphatic leukemia (CLL) and severe COVID-19. 18F-FDG PET/CT can be used to establish the diagnosis of RT in patients with CLL, but the use of 18F-FDG PET/CT to exclude RT as the cause of clinical deterioration in patients with CLL and severe COVID-19 has not previously been described. PATIENT CONCERNS: A 61-year-old male with CLL and COVID-19 developed increased dyspnea, malaise and fever during hospitalization for treatment of severe and prolonged COVID-19. DIAGNOSES: 18F-FDG PET/CT ruled out RT and revealed progression of opacities in both lungs consistent with exacerbation of severe acute respiratory syndrome coronavirus 2 pneumonia. INTERVENTIONS: 18F-FDG PET/CT imaging. OUTCOMES: The patient was discharged at day 52 without the need of supplemental oxygen, with normalized infection marks and continued care for CLL with venetoclax. LESSONS: 18F-FDG PET/CT ruled out RT as the cause of deteriorations in a patient with CLL and severe COVID-19, enabling directed care of exacerbation of severe acute respiratory syndrome coronavirus 2 pneumonia.
