Raynaud's disease and phenomenon [keywords]
- Systemic sclerosis and silicone breast implant: a case report and review of the literature. [Journal Article]
- Case Rep Rheumatol 2014.:809629.
Environmentally induced systemic sclerosis is a well-recognized condition, which is correlated with exposure to various chemical compounds or drugs. However, development of scleroderma-like disease after exposure to silicone has always been a controversial issue and, over time, it has triggered spirited debate whether there is a certain association or not. Herein, we report the case of a 35-year-old female who developed Raynaud's phenomenon and, finally, systemic sclerosis shortly after silicone breast implantation surgery.
- Seronegative polyarthritis revealing antisynthetase syndrome: a multicentre study of 40 patients. [JOURNAL ARTICLE]
- Rheumatology (Oxford) 2014 Oct 27.
The aim of this study was to determine the frequency and characteristics of antisynthetase syndrome (ASS) revealed by polyarthritis.First we conducted a retrospective single-centre study to assess the frequency of ASS patients who presented with polyarthritis without pulmonary and/or muscle symptoms. Secondly, we conducted a larger, multicentre study in order to describe the clinical characteristics of these patients. Exclusion criteria were the presence of RF, the presence of ACPA and overlap with another CTD.In the single-centre study, polyarthritis was the first manifestation in 12 of 45 ASS patients (27%). An additional 28 patients were collected for the multicentre study, resulting in a total population of 40 ASS patients who presented with polyarthritis. The mean delay from polyarthritis onset to ASS diagnosis was 27 months (s.d. 40). Pulmonary and muscle symptoms were uncommon at ASS diagnosis (40% and 32.5%, respectively) and were dramatically delayed [mean delay after polyarthritis onset of 41 months (s.d. 53) and 21 months (s.d. 14), respectively]. Mechanic's hands and cutaneous signs of DM occurred in 25% and 22.5%, respectively, with a mean delay of 10 months (s.d. 10) and 31 months (s.d. 21), respectively. When present (32%), RP was the earliest non-articular manifestation [mean delay 3 months (s.d. 23) after polyarthritis onset]. On HEp-2 cells, antinuclear and/or cytoplasmic fluorescence was found in 70% of cases, with specificity for various anti-aminoacyl tRNA synthetase (anti-ARS) antibodies.ASS may be revealed by polyarthritis. To decrease the delay in diagnosis of ASS, pulmonary and muscle symptoms and anti-ARS antibodies might usefully be searched for in seronegative polyarthritis patients, especially in those with RP.
- Nailfold capillaroscopic changes in dermatomyositis and polymyositis. [JOURNAL ARTICLE]
- Clin Rheumatol 2014 Oct 17.
Inflammatory myopathies (IM) are a group of muscle diseases occurring both in children and adults. Nailfold videocapillaroscopy (NVC) alterations are described in IM, but available data are discordant, including differences between polymyositis (PM) and dermatomyositis (DM). The aim of this study was to describe the capillaroscopic differences between PM and DM patients and possible correlation with clinical and serological features. We analyzed 52 unselected patients with IM in a cross-sectional study in a 6-month period. NVC findings of 29 DM and 23 PM patients were compared with those of 52 patients with primary Raynaud's phenomenon. Tortuosities, capillary loss, enlarged and giant capillaries, microhemorrhages, and ramified capillaries were scored by a semiquantitative rating; disorganization of the vascular array, avascular areas, and scleroderma pattern were scored as presence/absence. Sex, mean age, and mean disease duration were similar in both groups. Disorganization of the vascular array, enlarged and giant capillaries, capillary loss, and scleroderma-like pattern were observed almost only in IM patients. Significant differences were observed between PM and DM with higher frequency and mean score of NVC changes in DM. In DM patients with disease duration ≤6 months (14/29 patients), capillary density was significantly reduced (P = 0.039) and giant capillaries more frequent (P = 0.027), compared with patients with longer disease duration, while a scleroderma pattern tended to be more frequent in patients with a disease duration of less than 6 months. On the contrary, no differences were observed for ramified capillaries with regard to disease duration. Capillaroscopic alterations are identified only in DM patients as expression of diffuse microangiopathy; surprisingly, more severe changes were associated with shorter disease duration, while persistence of ramified capillaries with long-standing disease.
- Elevated plasma homocysteine level is possibly associated with skin sclerosis in a series of Japanese patients with systemic sclerosis. [Journal Article]
- J Dermatol 2014 Nov; 41(11):986-91.
Homocysteine is a sulfhydryl-containing amino acid that is derived from dietary methionine, and there has been increasing evidence that elevated plasma homocysteine levels are associated with increased risk of cardiovascular diseases, including carotid, coronary and peripheral arterial disease (PAD). The association of plasma homocysteine levels with peripheral vascular involvements, such as Raynaud phenomenon (RP), digital ulcers (DU) in systemic sclerosis (SSc) patients has not been well studied. The objective of this study was to examine plasma homocysteine levels and their clinical associations in patients with SSc. Plasma homocysteine levels in 151 Japanese patients with SSc and 20 healthy controls were examined. No significant differences were observed in plasma homocysteine levels between SSc patients and healthy individuals. Demographic and clinical features of the SSc patients revealed that severe skin sclerosis, anti-topoisomerase I antibody positivity, complications of DU, acro-osteolysis (AO) and interstitial lung disease (ILD) were significantly more prevalent among the patients with elevated plasma homocysteine levels. The plasma homocysteine levels were positively correlated with modified Rodnan total skin score. The plasma homocysteine levels in the SSc patients with DU, AO and ILD were significantly higher than those in the SSc without DU, AO and ILD, respectively. Plasma homocysteine levels did not correlate with either the mean or max intima-media thickness (IMT) or plaque score, suggesting that plasma homocysteine levels might not be associated with carotid artery atherosclerosis in SSc patients. The measurement of plasma homocysteine levels in SSc patients might be useful for the risk stratifications of severe skin sclerosis, DU and AO.
- Clinical differences between Thai systemic sclerosis patients with positive versus negative anti-topoisomerase I. [JOURNAL ARTICLE]
- Int J Rheum Dis 2014 Oct 8.
Anti-topoisomerase I antibody (ATA) carries an increased risk of systemic sclerosis (SSc) internal organ involvement. There have been no published comparisons of the clinical characteristics of patients positive and negative for ATA in Thailand, where the positive rate for ATA is higher than among Caucasians.To define the clinical differences between SSc, positive versus negative, for ATA.A retrospective cohort study was performed among SSc patients over 18 at Srinagarind Hospital, Khon Kaen University, Thailand, during January 2006-December 2013. SSc-overlap syndrome was excluded.Two hundred and ninety-four SSc patients were included (female : male 2.5 : 1). The majority (68.6%) were the diffuse cutaneous SSc subset (dcSSc). ATA was positive in 252 patients (85.7%), among whom 71.7% had dcSSc and 28.2% limited cutaneous SSc (lcSSc). Using a multivariate analysis, hand deformity had a significantly positive association with ATA (odds ratio [OR] 7.01; 95% CI 1.02-48.69), whereas being anti-centromere (ACA) positive had a negative association (OR 0.17; 95% CI 0.03-0.92). After doing a subgroup analysis of the SSc subset, the median duration of disease at time of pulmonary fibrosis detection among ATA positive dcSSc was significantly shorter than the ATA negative group (1.05 vs. 6.77 years, P = 0.01). Raynaud's phenomenon (RP) at onset was significantly more frequent in lcSSc sufferers who were ATA negative than those who were ATA positive (90.5% vs. 56.9%, P = 0.005).A high prevalence of ATA positivity was found among Thai SSc patients and this was associated with a high frequency of hand deformity, ACA negativity, a short duration of pulmonary fibrosis in dcSSc and a lower frequency of RP in lcSSc.
- Choroidal impairment and macular thinning in patients with systemic sclerosis: The acute study. [JOURNAL ARTICLE]
- Microvasc Res 2014 Sep 26.
Raynaud's phenomenon (RP) is a reversible vasospastic response of the extremities to cold or emotion, and can be the first manifestation or may be present before the development of an overt systemic sclerosis (SSc). The disturbance of the balance between vasodilation and vasoconstriction is not limited to the peripheral microcirculation of the skin, but it is also observed in other organs, such as the choroidal plexus of the eye. We aimed to examine the choroidal thickness (CT), the macular thickness and ganglion cell complex (GCC) average in thirty consecutive patients, without visual symptoms, classified as primary RP (pRP), RP secondary to suspected SSc, and overt SSc. All the patients underwent rheumatologic and ophthalmologic examination, capillaroscopy, test for anti-nuclear antibodies, anti-dsDNA, and anti-extractable nuclear antigens. Ophthalmologic examination included: best corrected visual acuity; slit lamp biomicroscopy; intraocular pressure measurements, fundus examination, and Spectral Domain-Optical Coherence Tomography (SD-OCT) with enhanced depth imaging scan system. Twenty-seven healthy subjects similar for gender and age were analyzed. In pRP, CT was significantly thinner than controls in the outer nasal and temporal regions. In secondary RP, the inner and outer nasal areas were significantly thinner than controls. In SSc, the central, inner inferior, inner nasal, inner superior, outer temporal, outer inferior, and outer nasal regions were significantly thinner than controls. A decreasing trend of central foveal thickness was noted. All the patients had GCC average significantly lower than controls. A thinning of choroidal and macular thickness, as well as of GCC was observed in patients with pRP and becomes more severe and extensive in RP secondary to suspected SSc and overt SSc. To our knowledge, this is the first study to analyze the choroidal features using SD-OCT in RP. These data may be clinically useful in suggesting an early involvement of ocular microcirculation with significant reduction of choroidal perfusion.
- The 2013 ACR/EULAR Classification Criteria for Systemic Sclerosis Out-perform the 1980 Criteria. Data from the Canadian Scleroderma Research Group. [JOURNAL ARTICLE]
- Arthritis Care Res (Hoboken) 2014 Sep 18.
Objective: The goal of this study was to determine the sensitivity of the new 2013 classification criteria for systemic sclerosis (SSc) in an independent cohort of SSc subjects and to assess the contribution of individual items of the criteria to the overall sensitivity. Method: SSc subjects from the Canadian Scleroderma Research Group cohort were assessed. Sensitivity was determined in several subgroups of patients. In patients without the criterion of skin thickening proximal to the metacarpophalangeal joints (MCPs), we re-calculated sensitivity after removing individual criterion. Results: A total of 724 SSc patients were included. Most were females (86%), mean age was 55.8 years, mean disease duration was 10.9 years, and 59% had lcSSc. Overall, the sensitivity of the 2013 criteria was 98.3% compared to 88.3% for the 1980 criteria. This pattern was consistent among those with lcSSc (98.8% versus 85.6%), anti-centromere antibodies (98.9% vs 79.8%), disease duration ≤ 3 years (98.7% vs 84.7%) and no skin involvement proximal to the MCPs (97% vs 60%). In the latter sub-group, removing Raynaud's phenomenon and sclerodactyly from the criteria reduced the sensitivity to 77% and 79%, respectively. Removing both sclerodactyly and puffy fingers reduced the sensitivity to 62%. Conclusion: The 2013 SSc classification criteria classify more SSc patients than the 1980 criteria. The improvement in sensitivity is most striking in those with lcSSc, especially those without skin involvement proximal to the MCPs. The addition of Raynaud's phenomenon and puffy fingers to the 2013 criteria accounts for important gains in sensitivity. © 2014 American College of Rheumatology.
- Antiphosphatidylserine and antiphosphatidylethanolamine antibodies in systemic lupus erythematosus: occurrence and association with clinical disease manifestations. [JOURNAL ARTICLE]
- Pol Arch Med Wewn 2014 Jun 20.
INTRODUCTION Antiphosphatidylethanolamine antibodies (aPE) and antiphosphatidylserine antibodies (aPS) belong to a group of antiphospholipid antibodies (aPL) that occur in patients with antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE). OBJECTIVES The aim of this study was to examine the relationship among the elevated serum concentration of aPE/aPS, the clinical manifestations of SLE, and the presence of other autoantibodies. PATIENTS AND METHODS The study group consisted of 71 SLE patients. The control group was made up of 36 healthy volunteers. In both groups aPS/aPE serum concentration was measured with enzyme immunoassays. Data, including clinical manifestations and the laboratory markers of SLE, were obtained from medical documentation. RESULTS The study revealed a higher prevalence of aPE in SLE patients than in the controls (54.93% vs. 5.56%). Compared with aPE, aPS occurred in the study group less frequently (12.68%) and were absent in the controls. Anticardiolipin antibodies (aCL) and APS were found to be related to aPS presence. Among aPS-positive SLE patients, thrombocytopenia, Raynaud's phenomenon, and myocardial infarction were observed more frequently. The study revealed that aPE presence predisposes the patient to mucosal ulcers. A positive correlation between aPS and ESR was also revealed. The serum concentration of aPE correlated negatively with red blood count (RBC) and positively with erythrocyte sedimentation rate (ESR). CONCLUSIONS The presence of aPS in SLE patients was found to be associated with thrombocytopenia, Raynaud's phenomenon, and cardiac complications.
- Partial fingertip necrosis following a digital surgical procedure in a patient with primary Raynaud's phenomenon. [JOURNAL ARTICLE]
- Int Wound J 2014 Sep 9.
Raynaud's phenomenon is a common clinical disorder consisting of recurrent, long-lasting and episodic vasospasm of the fingers and toes often associated with exposure to cold. In this article, we present a case of partial fingertip necrosis following digital surgical procedure in a patient with primary Raynaud's phenomenon.
- Guillain-Barré syndrome presenting with Raynaud's phenomenon: a case report. [Journal Article]
- BMC Neurol 2014; 14(1):174.
Guillain-Barré syndrome is an immune mediated acute inflammatory polyradiculo-neuropathy involving the peripheral nervous system. Commonest presentation is acute or subacute flaccid ascending paralysis of limbs. Rarely autonomic dysfunction can be the presenting feature of Guillain-Barré syndrome. Raynaud's phenomenon, although had been described in relation to many disease conditions, has not been described in association with Guillain-Barré syndrome up to date.We report the first case of Guillain-Barré syndrome presenting with Raynaud's phenomenon in a 21-year-old previously well boy. New onset Raynaud's phenomenon was experienced followed by acute ascending flaccid paralysis of lower limbs and upper limbs together with palpitations and postural giddiness. Nerve conduction studies showed acute inflammatory demyelinating polyneuropathy with cerebrospinal fluid cyto-protein dissociation. He was treated with intravenous immunoglobulin and showed a satisfactory clinical recovery of muscle weakness, Raynaud's phenomenon and autonomic disturbances.Guillain-Barré syndrome presenting with Raynaud's phenomenon is not being reported in literature previously. Although the underlying mechanism is not fully understood, Raynaud's phenomenon should prompt the physician to consider Guillain-Barré syndrome with a complimentary clinical picture.
