Objective.To conduct a retrospective study to assess whether the degree of thumb involvement differs between primary Raynaud’s phenomenon (PRP) and secondary Raynaud’s phenomenon (SRP).Methods.Thermography images from all patients attending Salford Royal Hospital and referred for thermography for assessment of RP between 2004 and 2006 were retrospectively reviewed. A distal dorsal difference (DDD) of −1°C or less between the fingertips and dorsum of the hand (fingers cooler) at 23°C was considered clinically relevant. The worse score (the lower score, i.e., the more negative value) from each pair of digits was considered for analysis.Results.One hundred seventy patients fulfilled the study criteria. DDD at 23°C for the thumbs were significantly higher (digital tips warmer) compared with other digits (p < 0.001) in both PRP and SRP. All digits were significantly warmer in PRP compared to SRP with the exception of the thumbs. The proportion of patients with clinically relevant involvement of thumbs was significantly higher in SRP compared to PRP (p = 0.003) and this difference was more pronounced in the thumbs compared with other digits.Conclusion.Although the median temperature gradient along the thumb was not significantly different between SRP and PRP, the thumb is more likely to be involved in SRP than in PRP. Thumb involvement is one of a number of clinical indicators that should alert the clinician to the possibility of an underlying connective tissue disease/disorder.

Colour Changes

In patients with Raynaud’s phenomenon (RP), the role of medical history, capillaroscopy, and autoantibodies in order to provide an early diagnosis of connective tissue disease (CTD) were examined. 115 consecutive adults with uni-, bi-, or triphasic colour changes of the fingers were studied. RP was bilateral in 92.7% of patients. The middle finger was significantly more affected. A lack of association between fingers affected by RP and fingers with capillary abnormalities was observedOR=0.75(0.34–1.66). RP with the cyanotic phase had a higher risk at capillaroscopy to have hemorrhagesOR=4.46(1.50–13.30) and giant capillariesOR=24.85(1.48–417.44). The thumb and triphasic involvement have an OR of 1.477 and 1.845, respectively. RP secondary to systemic sclerosis (SSc) had greater value of VAS pain (p=0.011). The presence of anti-centromere antibodies was significantly associated with a higher risk of SSc (p<0.001). 44.3% of subjects had uniphasic blanching of the fingers, and among these, 27% was diagnosed as having an overt or suspected CTD. Markers of a potential development of CTDs include severe RP symptoms, positive autoantibodies, and capillary abnormalities. These data support the proposal to not discharge patients with uniphasic blanching of the fingers to avoid missing the opportunity of an early diagnosis.

Objectives: To determine the relationship of antibodies to extractable nucleus antigens and connective tissue diseases identified by Immunoblot in a hospital in Lima, Peru. Material and methods: Study of the observational type, basic sciences, analytical and trans-versal, carried out in the Immunology service of the national Hospital Archbishop Loayza between January 2018 and June 2018. We analyzed 291 clinical histories of patients with connective tissue disease and for the detection of antibodies to the extractable antigens of the nucleus the method of Immunoblot was employed. Results: The frequency of the antibodies against extractable nuclear antigens in patients with connective tissue disease identified by Immunoblot was 789 (100%). It was demonstrated that there is significant relationship p < 0.05 of Anti-histones (X2 = 64.19; p = 0,000), an-ti-nucleosomas (X2 = 71,16; p = 0,000), anti-dsDNA (X2 = 71,44; p = 0,000), anti-SM (X2 = 10,08; p = 0,003) and Lupus Systemic erythematosus with Pearson Chi-square test. It was demons-trated that there is significant relationship p < 0.05 of the Anti-SSA (X2 = 61,33; p = 0.001), anti-SSB (x2 = 51,00; p = 0.001), anti-Ro 52 (X2 = 62,60; p = 0,000) and Sjogren’s syndrome with Pearson Chi-square test. It was demonstrated that there is significant relationship p < 0.05 of Anti-CENP B (p = 0.001) and calcinosis, Raynaud’s phenomenon, esophageal dysmotility, sclerodactyly and Telangiectasia (CREST) with exact Fisher statistician. Conclusions: There is a relationship of antibodies to extractable nucleus antigens and systemic lupus erythematosus, Sjogren’s syndrome, mixed connective tissue disease, calcinosis, Raynaud’s phenomenon, esophageal dysmotility, sclerodactyly and Telangiectasias (CREST), Scleroderma and Polymyositis.

Scleroderma Pattern

Background:Non-specific abnormalities could be detected by nailfold videocapillaroscopy (NVC) in subject with primary Raynaud’s Phenomenon (RP) several years before the clinical onset of connective tissue diseases (CTD)s [1]. Previous findings from our group proved that ≤30 μm capillary dilations in RP patients have a negative predictive value for developing the ‘scleroderma pattern’ during follow-up [2].Objectives:To investigate the role of NVC >30 μm capillary dilations as positive predictive factors of the ‘scleroderma pattern’ in RP patients later developing systemic sclerosis (SSc)-related RP.Methods:A 10-year retrospective NVC-based investigation evaluated the dataset of sequential NVCs of 18 RP patients later developing SSc (cases) and 19 sex- and age-matched RP patients later developing other CTDs (controls). Both cases and controls had ≥1 NVC performed before the ‘scleroderma pattern’/CTD diagnosis (basal NVC) showing >30 μm dilated capillaries. Each NVC was qualitatively and semi-quantitatively assessed, recording number of total capillaries, number and average/site-specific diameters (arterial, apical, venous) of >30 μm dilated capillaries [3]. Statistical analysis was performed to stratify the risk of developing the ‘scleroderma pattern’.Results:Significant differences of capillary diameters were observed between cases and controls both at basal NVC and during follow-up (p<0.001). The proportion of >30 μm dilated capillaries in basal NVC was the strongest predictor of ‘scleroderma pattern’ in a median 3-year time, with a 27% cut-off (PPV 0.79, 95%CI 0.54,0.94; p<0.001). Additional “Higher risk” NVC hallmarks for ‘scleroderma pattern’ development were apical diameter >40 μm (p<0.001), venous diameter >25 µm (p<0.05) and average diameter ≥35 µm (p<0.005). Conversely, CTDs patients showed a stable NVC ‘non-scleroderma pattern’ over a median 10-year time.Conclusion:This is the first study to show that NVC-detected homogeneous and progressive capillary loop dilations in RP patients significantly contribute to predict the ‘scleroderma pattern’ evolution within a median 3-year time, possibly providing a “very early” window of opportunity in SSc pre-clinical stages.References:[1]Cutolo M et al.
