RESUMO

OBJECTIVES: To determine the concentrations of circulating endostatin and angiostatin in patients with systemic sclerosis (SSc) and to assess its relationship to disease subsets, evolution phase, organ involvement and nailfold capillaroscopic changes. METHODS: Endostatin and angiostatin serum levels were measured by ELISA in a cohort of 57 patients with SSc, and correlated with disease subsets, evolution phase, organ involvement and nailfold capillaroscopic changes. RESULTS: Endostatin and angiostatin serum levels were significantly higher in patients with SSc than in healthy controls. Also, angiostatin was elevated in diffuse cutaneous SSc (dcSSc) and limited cutaneous SSc (lcSSc), but not in pre-SSc, while endostatin was increased in all SSc subsets. Moreover, endostatin was augmented in lcSSc, with or without CREST syndrome, whereas angiostatin was increased exclusively in patients with CREST. Analysis according to disease evolution phase found that endostatin was elevated in all phases while angiostatin was only significantly higher in intermediate and late phases of disease. Analysis regarding organ involvement revealed that angiostatin was significantly higher in patients with osteoarticular involvement and with more serious lung affection; no significant differences were found for endostatin. Finally, endostatin was significantly increased in all nailfold capillaroscopy stages, while angiostatin was only elevated in active and late phases. CONCLUSIONS: In accordance with previous studies, we found that endostatin and angiostatin concentrations are elevated in SSc patients. Additionally, we recognised the important role that endostatin might play as an early disease marker and realized that angiostatin is a marker of late disease and relates to lung disease severity.

RESUMO

BACKGROUND: Amyloidosis involving the breast is a rare finding and it may present as a solitary mass called 'amyloid tumor'. According to the largest case series, the amyloid deposits are usually of the AL type (commonly x03BA; light chain). METHODS: We report 3 cases diagnosed at our institution in the period from 2000 to 2015. Radiological, histological and immunohistochemical studies were performed. RESULTS AND CONCLUSIONS: Together with a case presenting in a patient with multiple myeloma, we describe 2 unique presentations including 1 associated with CREST syndrome in a patient with a previous history of breast carcinoma and another, also associated with cancer, with transthyretin deposits in a woman with a TTR gene mutation and a family history of familial amyloidotic polyneuropathy. These cases are an example of the vast heterogeneity of this disorder regarding its clinical presentation, the type of amyloid deposits and other diseases associated with breast amyloidosis.

RESUMO

Limited cutaneous systemic sclerosis (lcSSc) was formerly known as CREST syndrome in reference to the associated clinical features: calcinosis, Raynaud's phenomenon, esophageal dysfunction, sclerodactyly, and telangiectasias. The transforming growth factor beta has been identified as a major player in the pathogenic process, where low-level light therapy (LLLT) has been shown to modulate this cytokine superfamily. This case study was conducted to assess the efficacy of 940 nm using millisecond pulsing and continuous wave (CW) modes on osteoarticular signs and symptoms associated with lcSSc. The patient was treated two to three times a week for 13 weeks using a sequential pulsing mode on one elbow and a CW mode on the other. Efficacy assessments included inflammation, symptoms, pain, health scales, patient satisfaction, clinical global impression, and adverse effects monitoring. Considerable functional and morphologic improvements were observed after LLLT, with the best results seen with the pulsing mode. No adverse effects were noted. Pulsed LLLT represents a treatment alternative for osteoarticular signs and symptoms in limited scleroderma (CREST syndrome).

RESUMO

Cryoglobulinemic vasculitis is a rare entity. Although it has been reported in diffuse systemic sclerosis, it has not been reported in calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly and telangiectasia (CREST) syndrome. We report a patient with cryoglobulinemic vasculitis with CREST syndrome who did not have typical clinical features of vasculitis. This 58-year-old woman presented with mild generalized weakness and a diagnosis of CREST syndrome, which included Raynaud's syndrome, dysphagia and telangiectasias. She was positive for serum cryoglobulins, which led to a sural nerve biopsy. The biopsy results were consistent with cryoglobulinemic vasculitis. Cryoglobulinemic vasculitis has not been previously reported in CREST syndrome to our knowledge. Additionally, the patient also had limited clinical symptoms. Our patient displays the importance of checking for cryoglobulins and obtaining a nerve biopsy when the serum is positive. Both of these diagnostic tests were integral for directing appropriate treatment for this patient.

RESUMO

Telangiectasia are cardinal features of systemic sclerosis (SS) and calcinosis, Raynaud's syndrome, esophageal motility, sclerodactyly, telangiectasias (CREST) syndrome. The etiology of telangiectasia in these syndromes is unknown, but vascular dysfunction has been proposed. However, the telangiectasia of CREST have anecdotally been considered relatively resistant to pulse dye laser (PDL), the treatment of choice for classic telangiectasia. The study was designed to test whether SS/CREST telangiectasia require more treatments than sporadic telangiectasia and to identify clinical and histological features that could explain such an effect. Nineteen skin biopsies from patients with SS or CREST and 10 control biopsies were examined and compared for features that may predict a differential response to PDL. Sixteen cases of SS or CREST treated with PDL between 1997 and 2007 were evaluated and response to treatment was compared with 20 patients with sporadic telangiectasis. Relative to normal skin, CREST/scleroderma telangiectasia exhibited thickened vessels in 17 out of 19 sections and thickened collagen fibers in the reticular or deep dermis in all sections. The number of treatments required to clear SS/CREST telangiectasia was approximately twofold higher. SS/CREST telangiectasia are more resistant to PDL but can be effectively cleared with more treatments.

RESUMO

OBJECTIVE: We undertook this hypothesis-generating study to identify skin transcripts correlating with severity of interstitial lung disease (ILD) in systemic sclerosis (SSc). METHODS: Skin biopsy samples from 59 patients enrolled in the Genetics versus Environment in Scleroderma Outcome Study (GENISOS) cohort or an open-label imatinib study (baseline visit) were examined by global gene expression analysis using Illumina HT-12 arrays. Skin transcripts correlating with concomitantly obtained forced vital capacity (FVC) values and the modified Rodnan skin thickness score (MRSS) were identified by quantitative trait analysis. Also, immunofluorescence staining for selected transcripts was performed in affected skin and lung tissue. Plasma levels of CCL2, soluble SELP, and soluble P-selectin glycoprotein ligand 1 (sPSGL-1) were examined in all patients enrolled in the GENISOS cohort (n = 266). RESULTS: Eighty-two skin transcripts correlated significantly with FVC. This gene list distinguished patients with more severe ILD (FVC <70% predicted) in unsupervised hierarchical clustering analysis (P < 0.001). These genes included SELP, CCL2, and matrix metalloproteinase 3, which are involved in extravasation and adhesion of inflammatory cells. Among the FVC correlates, 8 genes (CCL2, HAPLN3, GPR4, ADCYAP1, WARS, CDC25B, PLP1, and STXBP6) also correlated with the MRSS. Immunofluorescence staining revealed that SELP and CCL2 were also overexpressed in affected skin and lung tissue from SSc patients compared to those from controls. Plasma levels of CCL2 and sPSGL-1 correlated with concomitantly obtained FVC values (r = -0.22, P = 0.001 and r = 0.17, P = 0.015, respectively). This relationship was independent of potential confounders (age, sex, ethnicity, smoking status, anti-topoisomerase I positivity, treatment with immunosuppressive agents, MRSS, disease type, and disease duration). CONCLUSION: A limited number of skin transcripts including genes involved in extravasation and adhesion of inflammatory cells correlate with severity of ILD.

RESUMO

OBJECTIVES: This paper aims to investigate the incidence of scleroderma spectrum disorders (SDS) in Slovenia. METHODS: From 01.01.2007 to 31.12.2009 we prospectively examined all patients over 18 years of age suspected of suffering from SDS who were referred to our department, which is the only Rheumatology referral centre in the Ljubljana region serving a population of 518.921 Caucasians over 18. Patient work-up consisted of clinical assessment, laboratory and imaging studies, and functional tests. The working classification of SDS proposed by Maricq and Valter was used to classify patients as having CREST syndrome, digital scleroderma disease (SD), intermediate SD, diffuse SD, undifferentiated connective tissue disease with SD features, and SD sine scleroderma. Patients with certain features of SDS who did not fit any specific class were classified as having prescleroderma using LeRoy's classification of early systemic sclerosis. RESULTS: We examined 100 patients. Forty-one new cases of SDS were diagnosed (37 females, 4 males), aged 58.9±15.1 years (24-86 years). CONCLUSIONS: The overall age-adjusted annual incidence of SDS in Slovenia is 2.6 per 100.000 adults per year (95%CI=1.7-3.5).

RESUMO

Como esclerodermia, se designa un grupo de enfermedades y síndromes que tienen como característica común la induración y el engrosamiento cutáneos. El síndrome CREST (calcinosis, fenómeno de Raynaud, alteraciones de la motilidad esofágica, esclerodactilia y telangiectasias) es una forma limitada de esclerodermia. En esta modalidad de la entidad es típico que el síndrome de Raynaud anteceda en años a la presentación del resto de los síntomas de enfermedad. En él pueden aparecer manifestaciones de fibrosis insterticial pulmonar, la cual se evidencia clínicamente por estertores húmedos bibasales, muchas veces sin otra forma de expresión, causa hipertensión pulmonar y fallo miocárdico. Es una enfermedad rara, más frecuente en mujeres que en hombres, de 35 a 50 años de edad. Está descrita en ancianos, pero la forma de CREST es muy infrecuente después de los 25 años. El objetivo fue presentar el caso de una mujer de 55 años de edad con un síndrome de CREST, un cor pulmonale y una evolución favorable. Es una entidad poco frecuente, pero que frente a su evidencia clínica debe insistirse en el diagnóstico positivo. Se trata de un caso interesante pues cursó con hipertensión pulmonar, cor pulmonale y su evolución fue satisfactoria...

RESUMO

We report a case of a 61-year-old man with a history of CREST syndrome (calcinosis cutis, Raynaud phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia) who presented for evaluation of thrombocytopenia. He had evident cervical adenopathy and lymph node biopsy showed small lymphocytic lymphoma (SLL) with evident systemic adenopathy and bone marrow involvement. The patient achieved a complete remission with FCR (fludarabine/cyclophosphamide/rituximab) chemotherapy. About 30 cases of lymphomas are reported in the literature in association with systemic sclerosis. To our knowledge, there are no reports of a small lymphocytic lymphoma (SLL) in association with limited cutaneous systemic sclerosis with classic features of the CREST syndrome.

RESUMO

CREST syndrome is part of the heterogeneous scleroderma group of autoimmune diseases that cause thickening, hardening and tightening of the connective tissue in different parts of the body, and it may lead to complex disorders. CREST syndrome is characterized by the coexistence of calcinosis, Raynaud's phenomenon, esophageal hypomotility, sclerodactily and telangectasia. A 72-year-old caucasian woman is referred to the S. Gerardo Hospital of Monza, with a chief complaint of oral pain and difficulties in deglutition and eating, associated with denture instability and difficulties to fit it. She had been previously diagnosed with Raynaud's phenomenon, and afterwards with CREST syndrome. Extra-oral examination underlined taut, thickened and rigid skin, pallid-red irregular maculae all over the face, telangiectasias and acrocyanosis. Intra-oral examination showed no alteration of the mucosa, but we can observe tongue rigidity and some speckled red alternating with white spots on the hard palate and in the vestibule. We undermitted the patient the dental treatment of Sjogren's syndrome. The management of the Sjogren's syndrome is symptomatic and empirical, and involves the use of saliva secretion stimulators, salivary substitutes and coadjuvants. Dental treatment and prophylaxis are important to prevent the consequences of xerostomia, such as rampant caries, based on the administration of topical fluoride in toothpastes and rinses, and supplemented by fluoride gels and varnishes. Instruction and reinforcement of oral hygiene, along with frequent dental assessment and management by the dentist are essential measures to preserve the oral health of those affected with CREST syndrome in progression to SS, complicated with Sjogren's syndrome.

RESUMO

The finding of intraoral telangiectasias in two patients previously diagnosed with Raynaud disease is reported. Neither patient exhibited any other feature of CREST syndrome, namely, calcinosis cutis, esophageal dysfunction, or sclerodactyly. To the authors' knowledge, this is the first time intraoral telangiectasias has been reported in conjunction with Raynaud disease in the absence of any other features of CREST syndrome.
