ABSTRACT
Background: During the COVID-19 pandemic, virtual consultation (VC) was used to replace in-person consultations. This raises specific questions when dealing with vulval conditions. Objectives: To assess the feasibility and the efficiency of VC with and without supplementary imaging, in patients with vulval conditions, and to evaluate the images provided as an aid to diagnosis. Methods: This prospective multicentre audit took place in three specialized vulval clinics in London and Paris. Anonymized data on patients' clinical characteristics, consultation characteristics (including the number and quality of any supplementary images provided) and consultation outcomes (diagnostic certainty and physician satisfaction) were collected. Characteristics and outcomes in those with or without supplementary imaging were compared amongst both new and follow-up consultations. Results: A total of 316 VCs were included. In total, 18.7% (n = 59) were new patient consultations and 81.3% (n = 257) were follow-up. Supplementary imaging (photographs and/or video recordings) were provided by 28.5% (n = 90) of the total cohort. Median photographic quality was significantly higher on a five-point Likert-type scale when photographs were taken by a third party as opposed to the patient themselves (4 vs. 3, Mann-Whitney U-test, p < 0.0001). There was no association between the provision of supplementary imaging and diagnostic certainty amongst new patient consultations. However, a higher proportion of follow-up patients who provided supplementary imaging received definitive management decisions (χ 2 test, p < 0.001) and physician satisfaction with these consultations, as measured on a five-point Likert-type scale, was significantly higher (Mann-Whitney U-test, p < 0.0001). Furthermore, median physician satisfaction scores ≥4 were observed in follow-up consultations for candidiasis, lichen simplex/eczema and vulvodynia. Conclusions: Although in-person consultation remains the gold standard of care, VC may have a role in the management of selected patients with vulval disease. It is possible to provide good-quality photographs for clinical assessment, particularly with the help of a third party and follow-up patients with an established, cancer-unrelated diagnosis may be best suited for this consultation modality.
ABSTRACT
During COVID-19 infection, reduced function of natural killer (NK) cells can lead to both compromised viral clearance and dysregulation of the immune response. Such dysregulation leads to overproduction of cytokines, a raised neutrophil/lymphocyte ratio and monocytosis. This in turn increases IL-6 expression, which promotes scar and thrombus formation. Excess IL-6 also leads to a further reduction in NK function through downregulation of perforin expression, therefore forming a pathogenic auto-inflammatory feedback loop. The perforin/granzyme system of cytotoxicity is the main mechanism through which NK cells and cytotoxic T lymphocytes eliminate virally infected host cells, as well as being central to their role in regulating immune responses to microbial infection. Here, we present epidemiological evidence suggesting an association between perforin expression and resistance to COVID-19. In addition, we outline the manner in which a pathogenic auto-inflammatory feedback loop could operate and the relationship of this loop to genes associated with severe COVID-19. Such an auto-inflammatory loop may be amenable to synergistic multimodal therapy.
