“…Another study found lower NMRI in PsA patients compared to control subjects, probably due to the close relationship between distal interphalangeal (DIP) enthesis and the nail matrix. According to those authors, the DIP enthesis inflammation extends into the nail matrix, resulting in vasodilatation and decreased RI [19,20]. Our results did not confirm previous studies' findings of differences in mean NMRI between PsA, PsO, and control groups.…”

Background Nail psoriasis occurs frequently in patients with psoriatic disease, it can lead to functional impairment, pain, discomfort, decreased quality of life and can also be a predictor for the development of arthritis. Early recognition of this condition can provide early and effective treatment and prevent structural impairment. This study aims to identify nail ultrasonographic characteristics in three groups: psoriasis (PsO), psoriatic arthritis (PsA) and controls patients, to determine if the ultrasonography (US) can identify early signs of nail psoriatic impairment or local inflammation. We conducted nail US to determine nail matrix resistance index (NMRI), nail bed resistance index (NBRI), and power Doppler (PD) and grayscale (GS) parameters in these 3 groups. Methods Single-center, cross-sectional study. GS, PD, and spectral doppler images of bilateral 2nd and 3rd fingernails were acquired from 35 PsO, 31 PsA, and 35 controls patients. An US equipment with an 18 MHz linear transducer for GS and 8.0 MHz for PD was used. PD, NMRI, NBRI, nail plate thickness (NPT), nail bed thickness (NBT), nail matrix thickness (NMT), and morphostructural characteristics of the trilaminar structure (TS) were evaluated in saved images, blind. Results Mean NMRI and NBRI did not differ between groups. Linear regression analysis detected no relationships between PsO or PsA and NMRI or NBRI. Nail PD grade did not differ between groups. Type I and IV TS changes were more frequent in PsO; types II and III changes were more frequent in PsA (p < 0.001). NPT was greater in PsA and PsO groups than controls: PsA 0.73 ± 0.14 mm, PsO 0.72 ± 0.15 mm, Controls 0.67 ± 0.10 mm (p = 0.001). Conclusion Echographic TS characteristics of the nail plate and NPT evaluated by GS are useful and can distinguish PsO and PsA nails from controls. NMRI, NBRI, and US nail microcirculation parameters could not distinguish psoriatic nails.

“…Presence of vascularity within the nail unit by ultrasonography Nail bed PD signals were variable in both patients with PsO and PsA across the studies, with a range varying from 20 to 96% [27,29,30,35,44]. A high frequency of vascularisation was also observed in healthy controls, ranging from 20 to 81.6% [27,35].…”

Background: Nail involvement has been described as a key clinical feature for both psoriasis (PsO) and psoriatic arthritis (PsA) and is an important risk factor in PsA. Thus, early diagnosis of nail involvement may be essential for better management of PsO and PsA. Ultrasonography is considered a highly promising method to visualize nail disease. The main aim of this review was to evaluate the use of ultrasonography for the diagnosis of nail disease in patients with PsO and PsA by reviewing ultrasound parameters with the best diagnostic accuracy. Main body of the abstract: A systematic search was performed in MEDLINE via the PubMed and LILACS databases. Conference proceedings of relevant rheumatology scientific meetings were also screened. Results: After applying eligibility criteria, only 13 articles and 5 abstracts were included in this review. The selected studies showed a huge variability in evaluation methods (and therefore in the results) and were mainly focused on the assessment of nails ultrasound parameters that may differ among patients and healthy controls, especially the morphological aspects in B-mode ultrasonography and vascularization of the nail bed by Doppler ultrasonography. Our research indicated that the evaluation of nail disease in PsO and PsA is still underrepresented in the literature, probably reflecting a restricted use in clinical practice, despite the widespread use of ultrasonography in the management of chronic arthritis. Short conclusions: Despite the potential relevance of ultrasonography for the diagnosis of nail disease, additional studies are needed to determine which features are more reliable and clinically pertinent to ensure accuracy in the evaluation of nail involvement in PsO and PsA.

Systematic study on nail plate assessment: differences in nail plate shape, thickness, power Doppler signal and scanning approach

et al. 2022

Ultrasonography (US) of the nail is raising interest in the last years and its feasibility, quickness and amount of descriptive data may provide valuable information. Different authors presented several scanning approaches to nail complex in different pathological conditions, such as psoriasis, but no scanning protocol was ever proposed using healthy subjects as population of reference. The aim of the study was to establish a protocol for the US of nail plate and to assess whether the measurement of the nail plate is influenced by longitudinal vs transverse scan, sex, digit and hand dominance. Using high frequency probe and a Canon Aplio i800 machine, ultrasonographers took scans of nail plates of the hands from healthy subjects. Nail plate shape, thickness and power Doppler signal (PDUS) were evaluated and scans were taken both on longitudinal and transverse axis, at distal, middle and proximal portion of the nail plate or at a fixed angles of − 45°, 0° or + 45°. All the images were then revised and scored using a DICOM software, in order to allow good standards of accuracy and reproducibility. A total of 27 subjects (14 females and 13 males) were assessed. The measures did not result to differ in different portions or angles. Furthermore, no difference appears in sex or dominant vs not dominant hand. A decreasing and significant trend for nail plate thickness was found from the first to the fifth finger. Doppler signal was found in all but one subjects, with a range from almost absent to very evident. No difference was found between groups regarding PDUS. The data provided suggest that a proper scan protocol should include all the nails and evaluation should be done both on longitudinal and transverse axis. Since Doppler signal is highly variable in healthy subjects, its presence should be carefully considered as pathological finding. Observations provided by this study clarify important points of the scanning technique and solve doubts related to which nails should be scanned and where to evaluate quantitative parameters.
