Manifestaciones cutáneas extraglandulares en pacientes con síndrome de Sjögren primario / Extraglandular cutaneous manifestations in patients with primary Sjögren's syndrome

RESUMEN Objetivos: Describir la frecuencia de manifestaciones cutáneas extraglandulares en pacientes con síndrome de Sjögren primario. Determinar el perfil clínico y de laboratorio de los pacientes que presentan estas manifestaciones en comparación con aquellos que no las presentan. Materiales y métodos: Se analizaron los datos de los pacientes incluidos en la base GESSAR (Grupo de Estudio Síndrome de Sjögren de la Sociedad Argentina de Reumatología). Para la comparación entre grupos, los controles se seleccionaron en forma aleatoria con una relación casos: controles de 1:4. A su vez, se compararon los pacientes con púrpura con los controles. Resultados: Sesenta y siete (14,1%) de los 474 pacientes incluidos en la base de datos tuvieron manifestaciones cutáneas extraglandulares. De ellos, el 58% tuvo púrpura. La artritis, la neuropatía, el descenso de C3 y de C4, y la crioglobulinemia fueron estadísticamente más frecuentes en los casos en comparación con los controles; sin embargo, no se encontró asociación independiente con ninguna de estas variables. En lo que respecta a púrpura, la artritis, la neuropatía periférica, la anemia, el descenso de C3 y de C4, anti-La y crioglobulinemia fueron estadísticamente más frecuentes en comparación con los controles. Solo el descenso de C4 y la positividad de crioglobulinas se asociaron en forma independiente a la presencia de púrpura. Conclusión: El 14% de los pacientes presentaron manifestaciones cutáneas extraglandulares. La púrpura fue la manifestación más frecuente. Esta se asoció en forma independiente con el descenso de C4 y la presencia de crioglobulinas.

ABSTRACT Objectives: To describe the frequency of extra-glandular cutaneous manifestations in patients with primary Sjögren's syndrome. To determine the clinical and laboratory profile of patients who present with these manifestations compared to those who do not. Materials and methods: A study was made of patients included in GESSAR database (Sjögren Syndrome Society of Argentina Rheumatology Study Group) were analyzed. For the comparison between groups, the controls were randomly selected, with a case:control ratio of 1:4. Patients with purpura were compared with controls. Results: A total of 67 (14.1%) of the 474 patients included in the database had extra-glandular cutaneous manifestations. Of them, 58% had purpura. Arthritis, neuropathy, a decrease in C3 and C4 levels, and the presence of cryoglobulins, were statistically more frequent in cases compared to controls, although there was no independent association found with any of these variables. As regards purpura, arthritis, peripheral neuropathy, anaemia, decrease in C3 and C4, anti-La, and cryoglobulinemia were statistically more frequent compared to controls. Only the decrease in C4, and the presence of cryoglobulins were independently associated with the presence of purpura. Conclusion: Extra-glandular cutaneous manifestations were observed in 14% of the patients. Purpura was the most frequent cutaneous manifestation. This was independently associated with decreased C4 and the presence of cryoglobulins.

Valoración de técnicas de citología en mucosa bucal en pacientes con síndrome de Sjögren / Assessment of cytology techniques in oral mucosa of Sjögren's syndrome patients

Resumen El objetivo del presente trabajo es comparar dos técnicas de estudio de citología bucal, la citología exfoliativa y de impresión, para evaluar cambios en la mucosa oral que permitan el diagnóstico no invasivo de síndrome de Sjögren (SS). Pacientes: Se seleccionaron 50 pacientes apareados por sexo y edad, diagnosticados con síndrome de Sjögren según criterios del Consenso Americano-Europeo. Los pacientes fueron distribuidos en tres grupos experimentales: controles sanos (C), n = 14, boca y ojo secos sin SS (BO), n = 13, y con SS n = 23. Material y métodos: Para la citología exfoliativa se utilizó cepillo recolector de células (Citobrush) deslizándolo a lo largo de la lámina de vidrio, fijándose posteriormente en etanol al 95%. En citologías por impresión se utilizó papel de acetato de celulosa (Milipore Hawp 304®), en tiras de un cm de longitud colocadas sobre la superficie de la mucosa bucal sobre el surco vestibular superior inmovilizando el papel y presionando por tres segundos. Se tiñeron con técnica de Papanicolau (PAP). Se valoró la morfología e histomorfometría, estudiando: área citoplasmática (AC), área nuclear (AN), relación núcleo-citoplasma (N:C) y cantidad de células por milímetro cuadrado (mm2). Resultados: Ambas técnicas nos permitieron observar en C: células epiteliales pavimentosas aisladas, basófilos, núcleos centrales normales, 20 a 30 por mm2, relación N/C 1:8. En el grupo BO: células aisladas, agrupadas y plegadas, con citoplasma a predominio eosinófilo, aumento de la cantidad de células 40 por mm2, relación núcleo-citoplasma relación N/C 1:4. En los pacientes SS se observó el área nuclear con cromatina más densa, 400 células por mm2, y relación N/C 1:2 en relación a BO y C. Hubo diferencias estadísticamente significativas entre los grupos en todas las características estudiadas. Conclusión: Podríamos inferir que la citología por impresión puede ser utilizada en el diagnóstico de lesiones orales y sistémicas en pacientes con hiposalivación.

Abstract The aim of the present research project was to compare two techniques for oral cytology study (exfoliative cytology and impression cytology) in order to assess changes in oral mucosa which might allow non -invasive diagnosis of Sjögren's syndrome cases (SS). Patients: 50 patients were selected, patients were paired by age and gender, and had been diagnosed with Sjögren's syndrome according to criteria of the American-European Consensus. Patients were distributed into the following three experimental groups: healthy control group (C), n = 14, Dry mouth and eyes group without SS, (ME) n = 13, and SS group n = 23. Material and methods: A cell harvesting brush (Cytobrush) was used for the exfoliative cytology procedure, sliding it along a glass plate and later fixating harvested cells in 95% ethanol. Cellulose acetate paper (Millipore Hawp 304®) was used for the impression cytology procedure. The paper was in 1 cm long stripes which were placed on the oral mucosa surface above upper vestibular groove; stripes were immobilized and pressure was applied for three seconds. Papanicolau (PAP) technique was used for dyeing. Morphology and histomorphology were assessed studying the following: cytoplasmic area (CA), nuclear areas (NA) nucleus-cytoplasm relationship (N:C) and amount of cells per square millimeter (mm2). Results: Both techniques revealed the following in C: isolated single-layered epithelial cells, basophils, normal central nuclei, 20 to 30 per mm2, N:C ratio 1:8. In the eye and mouth group (EM): grouped and folded isolated cells, cytoplasm with eosinophilic predominance increase of cell amount to 40 per mm2, nucleus-cytoplasm relationship N/C 1:4. SS patients showed the following: nuclear area with denser chromatin, 400 cells per mm2, and 1:2 N/C relationship with respect to mouth and ears and control. Statistically significant differences wereobserved among groups in all studied characteristics. Conclusion: We can infer that impression cytology can be used in systemic and oral lesion's diagnosis in patients afflicted with hyposalivation.

Manifestaciones salivales y bucales en aloholismo crónico / Salivary and oral manifestations in chronic aloholismo

La prevalencia de las enfermedades dentales entre los pacientes alcohólicos es frecuentemente extensa por la falta de interés en realizar una apropiada higiene oral y por la disminución del flujo salival. Además el consumo de tabaco empeora la patología dental y aumenta el riesgo de desarrollar el cáncer oral.(4-16) Es necesario el diagnóstico del paciente alcohólico, realizar un examen oral para identificar posibles alteraciones en la cavidad bucal lesiones de mucosa, (disgeusia) xerostomía, caries, pérdida de elementos dentarios, sialosis entre otros. Nuestro objetivo es Evaluar marcadores de diagnóstico en saliva y cavidad bucal en individuos con alcoholismo. Desarrollar estrategias para la prevención, eliminación o disminución de sus efectos deletéreos producidos sobre el efecto del alcohol sobre la cavidad bucal

ABSTRACT: The prevalence of dental disease among alcoholic patients is often extended by the lack of interest in a proper oral hygiene and decreased salivary low. Furthermore snuff consumption worsens dental disease and increases the risk of developing oral cancer. (4-16) is necessary diagnosis of alcoholic patients, oral examination to identify possible alterations in he oral cavity mucous membrane lesions (dysgeusia ) xerostomia, caries, loss of dental elements, sialosis among others. Our goal is to evaluate diagnostic marker sin saliva and oral cavity in individuals with alcoholism. Develop strategies for the prevention, elimination or reduction of its deleterious effects produced on the effect of alcohol on the oral cavity

Assessing the determination of salivary electrolytes and anti-Ro and anti-La antibodies for the diagnosis of Sjögren's syndrome (SS).

UNLABELLED: The aim of this study was to assess changes in salivary electrolyte flow and composition and the presence of anti-Ro/SSA and anti-La/SSB serum and saliva antibodies and their implications for the non-invasive diagnosis of SS. STUDY DESIGN: 73 patients were studied, divided into the following experimental groups: primary Sjögren syndrome (SSp) (n=15), secondary SS (SSs) (n=17), dry mouth, dry eye without Sjögren's syndrome (BO) (n=20) and healthy controls (C) (n=21). We conducted a baseline assessment of salivary flow and saliva sampling for the measurement of sodium, chlorine, potassium, calcium and phosphate electrolytes, and the determination of anti-Ro/SSA and La/SSB antibodies; a serum sampling was made to assess antibody positivity. RESULTS: Salivary flow in SSp, SSs and BO was significantly lower (p<0.001) relative to C. The salivary composition of SS showed an increase of inorganic components. Anti-Ro/SSA and anti-La/SSB antibodies occurred more frequently in serum and saliva in SS patients compared with BO and C, with higher frequency of positivity in serum compared with saliva. CONCLUSION: Our results suggest new tools that could aid the non-traumatic diagnosis of the origin of hyposalivation.

Oral signs of intravenous chemotherapy with 5-Fluorouracil and Leucovorin calcium in colon cancer treatment.

UNLABELLED: Several studies have shown how cytostatics may cause hypofunction of salivary glands but failed to elucidate any potentially related side effects. Keeping in mind the sialochemical assistance and the role of saliva on the homeostasis of the stomatognathic system, the aim of this study was to establish potential gland disorders in patients submitted to 5- Fluorouracil (5-Fu) and Leucovorin calcium (LV) as well as their correlation with certain oral health disorders that diminish the quality of life. MATERIALS AND METHODS: the focus of this research was observational and longitudinal. Twenty-five patients diagnosed with colon cancer at an initial, intermediate and late phase submitted to specifically devised therapy were assessed. Clinical history, oral health indexes and basal or stimulated saliva samples were recorded. RESULTS: Basal and stimulated flow dropped in the intermediate stage. Stimulated saliva pH decreased during treatment. On basal saliva, urea, sodium and potassium rose during the intermediate phase. Löe and Silness rates as well as simplified bleeding increased during therapy but reverted by the end of the treatment. Depth index of the vestibular gingival sulcus rose during the intermediate phase but did not return. CONCLUSION: This treatment caused functional salivary gland disorders as evidenced by basal and stimulated hyposialia, and acidification of stimulated saliva pH during the intermediate phase. Increase in basal urea may be due to proteic catabolism arising from plasma or glands. Variation in Na+ and K+ of basal saliva concentrates might be assumed as a possible duct disorder. Recovery of bleeding and Löe and Silness rates may point to a transient inflammatory effect associated to a decrease in salivary flow. Increase in the depth rates of the periodontal vestibular sulcus could be correlated with a higher risk of periodontal disease.
