RESUMO

Although rare, Angiostrongylus costaricensis infection may be a more prevalent etiology of inflammatory bowel disease than ulcerative colitis and Chron's disease in endemic areas in Central and South America. The present study reviewed the occurrence of A. costaricensis in Brazil, its clinical presentation and pathology; and proposed diagnostic criteria and case definitions for abdominal angiostrongyliasis (AA). Southern and southeastern Brazilian regions are the main endemic areas, and AA affects both genders and all age groups. A review of all 23 published reports of 51 Brazilian patients highlighted the following features that were subsequently classified as minor diagnostic criteria: abdominal pain, palpable mass in the right lower abdominal quadrant, history of exposure, ileocecal tumor, and intestinal perforation with wall thickening. Proposed major criteria include right lower quadrant abdominal pain, blood eosinophilia, positive serology (antibody detection), intense eosinophilic infiltration that involves all strata of the intestinal wall, eosinophilic granulomatous reaction, and eosinophilic vasculitis. In addition to the definitions of suspected and possible cases according to increasing strength of evidence of this infection, demonstration of worms/eggs/larvae in tissues or Angiostrongylus DNA in tissues or serum are required for a confirmed diagnosis. The application of the proposed criteria and definitions may improve patient management, epidemiologic surveillance, and identification of new endemic areas.

RESUMO

OBJECTIVES: Assess if kynurenines metabolites are biomarkers of damage at labial salivary gland biopsy (LSGB). METHODS: This is a cross-sectional study including 99 patients with primary Sjögren's syndrome (AECG 2002 or ACR/EULAR 2017). Kynurenines were measured in plasma using liquid chromatography-tandem mass spectrometry. RESULTS: 95.9% were females, 51±12 years. Most had focal lymphocytic sialadenitis with focus score ≥1 (73.7%, n=73/99). The majority had mild to severe acinar atrophy (70.4%, n=57/81) and adipose infiltration (51.2%, n=39/80). Individuals with adipose infiltration were older (53.49±12.33 vs. 47.51±11.29 years, p=0.016), showed higher frequency of glandular dysfunction and higher kynurenines levels. Schirmer's test ≤ 5 mm/5min was found in 69.2% of individuals with adipose infiltration compared to 41% without (p=0.012) and unstimulated whole salivary flow (UWSF) was found in 87.2% compared to 70% without adipose infiltration (p=0.063). Additionally, individuals with adipose infiltration showed higher kynurenines metabolites compared with those without: quinolinic acid (503.35±193.30 vs. 427.35±285.76 nmol/L, p=0.029), kynurenine (1.99±0.6, 54 vs. 1.61±0.46 µmol/L, p=0.006), kynurenine/tryptophan ratio (KTR) (0.030±0.09 vs. 0.025±0.01, p=0.031) and anthranilic acid (03±4.96 vs. 16.46±5.24 nmol/L, p=0.022). CONCLUSIONS: Kynurenines are biomarkers of greater adipose infiltration in LSGB and glandular dysfunction suggesting that activation of interferon-γ pathway is involved in the salivary and lacrimal glands damage.

RESUMO

BACKGROUND: Diabetic nephropathy (DN) is one of the major causes of end-stage renal disease in diabetic patients. Increasing evidence from studies in the rodents has suggested that this disease is associated with increased oxidative stress due to hyperglycemia. In the present study, we evaluated the renoprotective, anti-oxidative and anti-apoptotic effects of the flavonoid quercetin in C57BL/6J model of DN. METHODS: DN was induced by streptozotocin (STZ, 100 mg/kg/day, for 3 days) in adult C57BL/6J mice. Six weeks later, mice were divided into the following groups: diabetic mice treated with quercetin (DQ, 10 mg/kg/day, 4 weeks), diabetic mice treated with vehicle (DV) or non-treated non-diabetic (ND) mice. RESULTS: Quercetin treatment caused a reduction in polyuria (~45%) and glycemia (~35%), abolished the hypertriglyceridemia and had significant effects on renal function including, decreased proteinuria and high plasma levels of uric acid, urea and creatinine, which were accompanied by beneficial effects on the structural changes of the kidney including glomerulosclerosis. Flow cytometry showed a decrease in oxidative stress and apoptosis in DN mice. CONCLUSION: Taken together, these data show that quercetin effectively attenuated STZ-induced cytotoxicity in renal tissue. This study provides convincing experimental evidence and perspectives on the renoprotective effects of quercetin in diabetic mice and outlines a novel therapeutic strategy for this flavonoid in the treatment of DN.

RESUMO

BACKGROUND: Diagnosis of SS is a complex task, as no symptom or test is unique to this syndrome. The American-European Consensus Group (AECG 2002) and the American-European classification criteria of 2016 (ACR/EULAR 2016) emerged through a search for consensus. This study aims to assess the prevalence of Sjögren's Syndrome (SS) in patients with Systemic Lupus Erythematosus (SLE), according to AECG 2002 and ACR-EULAR 2016 classifications, as well as clinical and histopathological features in this overlap. To date, there is no study that has evaluated SS in SLE, using the two current criteria. METHODS: This cross-sectional study evaluated 237 SLE patients at the outpatient rheumatology clinic between 2016 and 2018. Patients were submitted to a dryness questionnaire, whole unstimulated salivary flow (WUSF), "Ocular Staining Score" (OSS), Schirmer's test I (ST-I), and labial salivary gland biopsy (LSGB). RESULTS: After verifying inclusion and exclusion criteria, a total of 117 patients were evaluated, with predominance of females (94%) and mixed ethnicity (49.6%). The prevalence of SS was 23% according to AECG 2002 and 35% to ACR-EULAR 2016. Kappa agreement between AECG 2002 and ACR-EULAR 2016 were 0.7 (p < 0.0001). After logistic regression, predictors for SS were: anti/Ro (OR = 17.86, p < 0.05), focal lymphocytic sialadenitis (OR = 3.69, p < 0.05), OSS ≥ 5 (OR = 7.50, p < 0.05), ST I positive (OR = 2.67, p < 0.05), and WUSF ≤ 0.1 mL/min (OR = 4.13, p < 0.05). CONCLUSION: The prevalence of SS in SLE was 23% (AECG 2002) and 35% (ACR-EULAR 2016). The presence of glandular dysfunction, focal lymphocytic sialadenitis, and anti/Ro were predictors of SS in SLE. The greatest advantage of the new ACR-EULAR 2016 criteria is to enable an early diagnosis and identify the overlapping of these two diseases. ACR-EULAR 2016 criteria is not yet validated for secondary SS and this study is a pioneer in investigating prevalence based on the new criteria.

RESUMO

Sjogren's Syndrome (SS) is an autoimmune disease characterized by lymphocytic infiltration of the exocrine glands and other organs, associated with sicca syndrome but also with systemic involvement with varying degrees of severity. Despite their importance, these systemic manifestations are not routinely evaluated and there is no homogenous approach to their diagnosis or evaluation. To close this gap, a panel of experts from the Brazilian Society of Rheumatology conducted a systematic review and meta-analysis on the identification of epidemiologic and clinical features of these manifestations and made recommendations based on the findings. Agreement between the experts was achieved using the Delphi method. The first part of this guideline summarizes the most important topics, and 11 recommendations are provided for the articular, pulmonary, and renal care of SS patients.

RESUMO

Sjogren's syndrome (SS) is an autoimmune disease characterized by lymphocytic infiltration of the exocrine glands and other organs, associated with sicca syndrome but also with systemic involvement with varying degrees of severity. Despite their importance, some systemic manifestations, mainly liver, gastrointestinal, and pancreatic are not routinely evaluated. To address these manifestations, the Sjögren's Syndrome Committee of the Brazilian Society of Rheumatology conducted a broad systematic review of the literature on studies investigating prevalence and diagnosis of these symptoms in Sjogren´s patients and made recommendations based on the findings. Agreement between the experts was achieved using the Delphi method. This is the second part of this guideline, providing 6 recommendations for liver, gastrointestinal, and pancreatic care of SS patients.

RESUMO

The androgen nandrolone decanoate (ND) is known to cause cardiovascular abnormalities, such as attenuation of the Bezold-Jarisch Reflex (BJR), cardiac hypertrophy, and elevation of mean arterial pressure (MAP). Futhermore, a relationship between androgens and the renin-angiotensin system (RAS) has been reported. The purpose of this study was to evaluate the influence of RAS on the BJR, cardiac and prostatic hypertrophy, and MAP evoked by ND. For this, male Wistar rats were treated with ND (10 mg·(kg body mass)(-1) for 8 weeks; DECA), or vehicle (control animals; CON), or enalapril (10 mg·(kg body mass)(-1), daily; CONE), or ND and enalapril (10 mg ND + 10 mg enalapril per kilogram of body mass; DECAE). After 8 weeks of treatment, the BJR was evaluated by bradycardia and hypotensive responses that were elicited by serotonin administration (2-32 µg·(kg body mass)(-1)). MAP was assessed; cardiac and prostate hypertrophy were determined by the ratio of the tissue mass:body mass, and by histological analysis of the heart. Animals from the DECA group showed prostatic and cardiac hypertrophy, elevation in mean arterial pressure, and an impairment of BJR. Co-treatment with enalapril inhibited these changes. The data from the present study suggest that RAS has an impact on BJR attenuation, cardiac and prostatic hypertrophy, and the elevation in MAP evoked by ND.

RESUMO

Lactating adenoma is a rare benign breast lesion that most often presents as a small (up to 3 cm), solid, well-circumscribed, solitary, painless, mobile, lobulated mass. The highest incidence occurs in primiparous women (20 to 40 years old) during the third trimester of pregnancy. However, in the rare case presented herein, in addition to its giant size (more than 10 centimeters on palpation), this lactating adenoma is distinctive due to the presence of multiple nodules, poorly defined ultrasonographic margins, worrisome radiologic features, growth since early pregnancy, presence of infarction and association with chronic mastitis. From the clinical-radiologic perspective, the differential diagnoses included abscess associated with puerperal mastitis, phyllodes tumor, and galactocele. Biopsy was performed, and pathologic examination revealed the classic characteristics of lactating adenoma with multiple infarcted areas, leading to an unexpected confirmed case of giant lactating adenoma.

RESUMO

The study aimed to estimate the prevalence of sexually transmissible infections (STIs) and associated factors in women in quilombola (maroon) communities in Brazil. This was a population-based cross-sectional study of quilombola women from March 2017 to January 2019. A questionnaire was used with sociodemographic, behavioral, and clinical information. A gynecological examination was performed for the collection of uterine cervical cells for oncotic cytology and the detection of Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, and human papillomavirus (HPV) via polymerase chain reaction. Rapid tests for HIV and syphilis were performed. The main outcome was defined as infection with one or more sexually transmissible pathogens. The analysis used chi-square test and hierarchical logistic regression. From a total of 380 women, 352 (92.6%) were included in the study. Prevalence of at least one STI was 18.5% (95%CI: 14.76-22.85). The highest prevalence was for HPV, with 11.1%, followed by 6.3% for T. vaginalis and 4.3% for C. trachomatis. There were no cases of N. gonorrhoeae. Prevalence was 0.3% for HIV and 4.3% for syphilis. Cervical-vaginal cytology was altered in 7.7% of the women. Detection of one or more STIs was significantly associated with age 25 to 44 years (OR = 2.33; 95%CI: 1.05-5.18), alcohol consumption (OR = 1.96; 95%CI: 1.06-3.64), altered cervical cytology (OR = 3.96; 95%CI: 1.65-9.48), and bacterial vaginosis (OR = 3.61; 95%CI: 2.01-6.47). Quilombola women showed high prevalence of one or more STIs, emphasizing the importance of organizing prevention strategies targeted to these women.


O objetivo do estudo foi estimar a prevalência de infecções sexualmente transmissíveis (IST) e fatores associados sobre mulheres quilombolas no Brasil. Trata-se de estudo transversal de base populacional com mulheres quilombolas no período de março de 2017 a janeiro de 2019. Utilizou-se um questionário com informações sociodemográficas, comportamentais e clínicas. Foi realizado exame ginecológico para coleta de células cervicais para citologia oncótica e para detecção de Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis e papilomavírus humano (HPV), por meio de teste de reação em cadeia pela polimerase. Foi realizado teste rápido para HIV e sífilis. O desfecho principal foi definido como a infecção por um ou mais agentes infecciosos de transmissão sexual. Para a análise, utilizou-se o teste do qui-quadrado e regressão logística hierárquica. De um total de 380 mulheres, 352 (92,6%) foram incluídas no estudo. A prevalência de, pelo menos, uma IST foi de 18,5% (IC95%: 14,76-22,85). A maior prevalência foi de 11,1% por HPV, seguido de 6,3% por T. vaginalis e de 4,3% por C. trachomatis. Não houve nenhum caso de N. gonorrhoeae. Para o HIV, a prevalência foi de 0,3%, e de sífilis foi de 4,3%. A citologia cervicovaginal estava alterada em 7,7%. A detecção de uma ou mais IST foi significativamente associada a idade entre 25 e 44 anos (OR = 2,33; IC95%: 1,05-5,18), a consumo de álcool (OR = 1,96; IC95%: 1,06-3,64), a resultado alterado da citologia (OR = 3,96; IC95%: 1,65-9,48) e a vaginose bacteriana (OR = 3,61; IC95%: 2,01-6,47). Em mulheres quilombolas houve elevada prevalência de uma ou mais IST, o que torna importante a elaboração de estratégias de prevenção direcionadas a essas mulheres.

RESUMO

BACKGROUND: Clinical improvements following highly active antiretroviral therapy (HAART) may increase high-risk behaviors resulting in sexually transmitted infections (STI). Optimism related to the success of HAART in slowing disease progression, reducing viral load, and improving health status might be important factors for increasing sexual risk behaviors such as less use of condoms. OBJECTIVE: To determine the prevalence of Chlamydia trachomatis, Neisseria gonorrhoeae, syphilis, hepatitis B and C, high-risk HPV, and cervical cytological abnormalities among women living with HIV (WLHIV) who attended a Reference Center for STI/AIDS in Brazil. METHODS: A cross-sectional study was conducted among 151 WLHIV attending an STI Clinic in Vitória city, Brazil. A structured questionnaire, including demographic, behavioral, and clinical information, was used for data collection. Serological tests for HIV, syphilis, hepatitis C and B, CD4 counts, and viral load determination were performed. Cervical samples were collected for cytology and real-time PCR for HPV,Chlamydia, and Neisseria gonorrhoeae. RESULTS: In this study, 59% of women had at least one diagnosed STI at the time of the first clinic visit; 31% had clinical forms of anogenital HPV, 10% syphilis, 8%Neisseria gonorrhoeae, 5.0% trichomoniasis, 3% Chlamydia trachomatis, 1% hepatitis B, and 1% hepatitis C; 6.7% of the women presented with cervical cytological abnormalities. Furthermore, 46.3% of women had HR-HPV, and 17.6% had HPV 16/18. Only 5% of the women had a CD4 count <200 cells/mm3, 61.6% had undetectable HIV viral load, and 81.3% were currently on HAART. CONCLUSION: A high prevalence of STI and HR-HPV infections were observed among HIV-infected women in this investigation. Prevention programs need to focus on counseling WLHIV and their regular partners with focused interventions such as couples counseling and education programs.

RESUMO

Sjogren's syndrome (SS) is an autoimmune disease characterized by lymphocytic infiltration of the exocrine glands and other organs. Women with SS often experience gynecological symptoms due to the disease and need extra care regarding their sexual activity, reproductive health and during pregnancy, conditions that are not properly conducted in the clinical practice. To cover this gap, a panel of experts from the Brazilian Society of Rheumatology conducted a systematic review and meta-analysis on the identification of symptoms, diagnosis, monitoring, prognosis, and treatment of these manifestations. A Focus Group meeting was held and included experts in the field and methodologists, based on a previously developed script, with themes related to the objective of the study. The most important topics were summarized and 11 recommendations were provided.

RESUMO

We investigated the influence of long-term treatment with supraphysiological doses of an anabolic-androgenic steroid on the Bezold-Jarisch reflex (BJR) control of heart rate (HR) and diastolic arterial pressure (DAP), and whether this treatment induced cardiac hypertrophy. Male rats were treated with nandrolone decanoate (ND) (10 mg kg(-1) body weight for 8 weeks; DECA) or vehicle (control animals; CON). After 8 weeks of treatment, the BJR was evaluated by bradycardia and hypotension responses that were elicited by serotonin administration (2-32 microg kg(-1)). Mean arterial pressure (MAP) was assessed and cardiac hypertrophy was determined by the ratio of the left and right ventricle weight/body weight (LVW/BW and RVW/BW, respectively) and by histological analysis. Total body protein (TBP) content was also evaluated. Nandrolone decanoate treatment increased MAP (CON=99+/- 1 mmHg; DECA=109+/-2 mmHg; p<0.01) but did not change the mean basal HR (CON=356+/-13 bpm; DECA=367+/-11 bpm). The treatment also induced LV and RV hypertrophy (LVW/BW: CON=1.86+/-0.04 mg g(-1), DECA=2.17+/-0.04 mg g(-1), p<0.01; RVW/BW: CON=0.42+/-0.02 mg g(-1), DECA=0.53+/-0.03 mg g(-1), p<0.05) and reduced the number of myocyte nuclei/high-power field (CON=23.0+/-2; DECA=9.4+/-1.0; p<0.01). ND treatment blunted the HR and DAP decreases induced by serotonin. ND determines an increase in the TBP content in DECA group (35+/-3%; p<0.01) compared with control animals (18+/-1%). We conclude that 8 weeks of ND treatment induces anabolic effect, cardiac hypertrophy and an elevation of MAP. This treatment also reduces the sensitivity of the BJR control of bradycardia and blood pressure, possibly due to cardiac hypertrophy. The blunted BJR response could contribute to the MAP elevation in DECA animals.

RESUMO

BACKGROUND: Primary Sjögren's syndrome (pSS) is a systemic immune-mediated disease whose main characteristic is exocrine gland inflammation and, subsequent reduction in tear and saliva production. A delayed diagnosis is common due to the nonspecific clinical manifestations of disease. The aim of the present study was to develop recommendations for the diagnosis of glandular manifestations of pSS based on evidence and expert opinion. We conducted a systematic literature review to retrieve the best evidence available on the accuracy of diagnostic tests for pSS. We also held two in-person meetings with experts (rheumatologists, pathologists, ophthalmologists and dentists) to establish their level of agreement using the Delphi method. Ultimately, we generated 18 recommendations that aim to facilitate the diagnosis of the glandular manifestations of pSS. CONCLUSION: The diagnosis of glandular manifestations of pSS is complex and multidisciplinary. It requires specific knowledge in the field of ophthalmology, immunology, pathology and imaging, making it compulsory for the rheumatologist to work with professionals from these different areas in order to improve accuracy and early diagnosis. Glandular dysfunction tests, ANA, RF, Anti-Ro, protein electrophoresis, urinalysis, blood count, C-Reactive protein, complement, testing for syphilis and viruses (HCV, HIV) and SGUS should be investigated when dryness or systemic manifestation are present. Minor salivary gland biopsy is recommended for all anti-Ro negative or incomplete criteria cases.

RESUMO

BACKGROUND: Little is known about the prevalence and impact of risk of malnutrition on short-term mortality among seniors presenting with acute heart failure (AHF) in emergency setting. The objective was to determine the impact of risk of malnutrition on 30-day mortality risk among older patients who attended in Emergency Departments (EDs) for AHF. MATERIAL AND METHODS: We performed a secondary analysis of the OAK-3 Registry including all consecutive patients ≥65 years attending in 16 Spanish EDs for AHF. Risk of malnutrition was defined by the Mini Nutritional Assessment Short Form (MNA-SF) < 12 points. Unadjusted and adjusted logistic regression models were used to assess the association between risk of malnutrition and 30-day mortality. RESULTS: We included 749 patients (mean age: 85 (SD 6); 55.8% females). Risk of malnutrition was observed in 594 (79.3%) patients. The rate of 30-day mortality was 8.8%. After adjusting for MEESSI-AHF risk score clinical categories (model 1) and after adding all variables showing a significantly different distribution among groups (model 2), the risk of malnutrition was an independent factor associated with 30-day mortality (adjusted OR by model 1 = 3.4; 95%CI 1.2-9.7; p = .020 and adjusted OR by model 2 = 3.1; 95%CI 1.1-9.0; p = .033) compared to normal nutritional status. CONCLUSIONS: The risk of malnutrition assessed by the MNA-SF is associated with 30-day mortality in older patients with AHF who were attended in EDs. Routine screening of risk of malnutrition may help emergency physicians in decision-making and establishing a care plan.

RESUMO

Traditional Periodic Acid Schiff has been extensively used, coupled with immunohistochemistry for epithelia or mesenchymal cells, to highlight renal tubular basement membrane (TBM). We recently tried to perform such technique in a 5/6 nephrectomy model of progressive renal fibrosis to demonstrate TBM disruption as an evidence for epithelial-mesenchymal transdifferentiation. Despite excellent basement membrane staining with traditional fuchsin-Periodic Acid Schiff, the interface between epithelial and mesenchymal cells was frequently blurred when revealed with 3'3 diaminobenzidine tetrachloride-peroxidase. Also, it was inadequate when revealed with alkaline phosphatase-fast red. We devised a triple staining method with Periodic Acid-Thionin Schiff to highlight basement membrane in blue, after double immunostaining for epithelium and mesenchymal cells. Blue basement membrane rendered a brisk contrast and highlighted boundaries between epithelial-mesenchymal interfaces. This method was easy to perform and useful to demonstrate the TBM, yield a clear demonstration of the very focal TBM disruption found in this model of progressive renal fibrosis.

RESUMO

BACKGROUND: We investigated the influence of short-term treatment with supraphysiological doses of an anabolic-androgenic steroid on the Bezold-Jarisch reflex (BJR) control of heart rate (HR) and whether this treatment induced cardiac hypertrophy and anabolic effects in rats. METHODS: Male rats were treated with nandrolone decanoate (10 mg/kg(-1) body weight/4 weeks; DECA) or vehicle control (CON). After 4 weeks of treatment, BJR was evaluated by bradycardia responses that were elicited by serotonin administration (2-32 microg/kg(-1)). Mean arterial pressure (MAP) was assessed and cardiac hypertrophy was determined by the left ventricle weight/body weight (LVW/BW) ratio. Histological analyses of LV and the measurement of the total body protein content of the animals were performed. RESULTS: Nandrolone decanoate (ND) treatment had no effect on the MAP (CON=105+/-5; DECA=110+/-3 mmHg). However, the mean basal HR of DECA animals was significantly lower than that of control animals (CON = 381+/-14; DECA=324+/-12 bpm; p<0.01). ND did not change the sensitivity of the BJR. The LVW/BW ratio indicated significant hypertrophy of the LV in DECA animals (CON=1.76+/-0.04; DECA=2.0+/-0.04 mg/g; p<0.01). Histological and morphometrical analyses demonstrate that there is also modest myocyte hypertrophy (CON=14.5+/-1.5; DECA=20.0 +/- 0.9 myocyte nuclei/field; p<0.05). However, the Masson-trichromic-stained samples showed an enhancement of collagen deposits on the LV matrix. CONCLUSIONS: We concluded that 4 weeks ND treatment induced an anabolic effect and the beginnings of LV remodeling, mainly due to excessive collagen deposition in the cardiac extracellular matrix. However, the treatment did not influence BJR control of bradycardia, an effect that could be explained by an enhanced efferent vagal tonus in DECA animals.

RESUMO

OBJECTIVE: to know the epidemiological profile of patients undergoing surgery for well-differentiated thyroid carcinoma at the Cassiano Antônio Moraes University Hospital of the Federal University of Espírito Santo, as well as the oncological results and the main postoperative complications. METHODS: we conducted a cross-sectional, retrospective study of patients with well-differentiated thyroid carcinoma (WDTC) operated from January 2008 to December 2015. RESULTS: During the study period, 95 of the 353 patients undergoing surgical treatment of the thyroid gland had WDTC. Papillary carcinoma was the most frequent (91.57%). Total thyroidectomy not associated with cervical emptying was the most frequent surgical procedure (65.26%). Postoperative complications occurred in 6.31% of patients, hematoma being the most frequent. The mean follow-up time was 36.9 months. Relapse occurred in four patients (4.21%), being locoregional in all cases. The prognostic factors analyzed, such as gender, age, tumor size, lymph node involvement, staging, type of surgery, histology and complementary iodine therapy did not show statistical significance. CONCLUSION: papillary carcinoma was the most common thyroid malignant neoplasm, affecting women in the 49-year-old age group more frequently. Loco-regional recurrence occurred in four patients. Hematoma was the most frequent complication.


OBJETIVO: conhecer o perfil epidemiológico dos pacientes submetidos à cirurgia do carcinoma bem diferenciado da tireoide no Hospital Universitário Cassiano Antônio Moraes da Universidade Federal do Espírito Santo, assim como os resultados oncológicos e as principais complicações pós-operatórias. MÉTODOS: estudo transversal e retrospectivo de pacientes portadores de carcinoma bem diferenciado da tireoide operados no período de janeiro de 2008 a dezembro de 2015. RESULTADOS: no período do estudo, dos 353 pacientes submetidos a tratamento cirúrgico da glândula tireoide, 95 eram portadores de CBDT. O carcinoma papilífero da tireoide foi o mais frequente (91,57%). A tireoidectomia total não associada a esvaziamento cervical foi o procedimento cirúrgico mais frequente (65,26%). As complicações pós-operatórias ocorreram em 6,31% dos pacientes, sendo o hematoma a mais frequente. O tempo médio de seguimento foi de 36,9 meses. A recidiva ocorreu em quatro pacientes (4,21%), sendo locorregional em todos os casos. Os fatores prognósticos analisados, como sexo, idade, tamanho do tumor, acometimento linfonodal, estadiamento, tipo de cirurgia, histologia e iodoterapia complementar não demonstraram significância estatística. CONCLUSÃO: o carcinoma papilífero da tireoide foi a neoplasia maligna mais frequente, acometendo o sexo feminino na faixa etária dos 49 anos mais frequentemente. A recidiva locorregional ocorreu em quatro pacientes. O hematoma foi a complicação mais frequente.

RESUMO

Abstract Background Diagnosis of SS is a complex task, as no symptom or test is unique to this syndrome. The American-European Consensus Group (AECG 2002) and the American-European classification criteria of 2016 (ACR/EULAR 2016) emerged through a search for consensus. This study aims to assess the prevalence of Sjögren's Syndrome (SS) in patients with Systemic Lupus Erythematosus (SLE), according to AECG 2002 and ACR-EULAR 2016 classifications, as well as clinical and histopathological features in this overlap. To date, there is no study that has evaluated SS in SLE, using the two current criteria. Methods This cross-sectional study evaluated 237 SLE patients at the outpatient rheumatology clinic between 2016 and 2018. Patients were submitted to a dryness questionnaire, whole unstimulated salivary flow (WUSF), "Ocular Staining Score" (OSS), Schirmer's test I (ST-I), and labial salivary gland biopsy (LSGB). Results After verifying inclusion and exclusion criteria, a total of 117 patients were evaluated, with predominance of females (94%) and mixed ethnicity (49.6%). The prevalence of SS was 23% according to AECG 2002 and 35% to ACR- EULAR 2016. Kappa agreement between AECG 2002 and ACR-EULAR 2016 were 0.7 (p < 0.0001). After logistic regression, predictors for SS were: anti/Ro (OR = 17.86, p < 0.05), focal lymphocytic sialadenitis (OR = 3.69, p < 0.05), OSS ≥ 5 (OR = 7.50, p < 0.05), ST I positive (OR = 2.67, p < 0.05), and WUSF ≤ 0.1 mL/min (OR = 4.13, p < 0.05). Conclusion The prevalence of SS in SLE was 23% (AECG 2002) and 35% (ACR-EULAR 2016). The presence of glandular dysfunction, focal lymphocytic sialadenitis, and anti/Ro were predictors of SS in SLE. The greatest advantage of the new ACR-EULAR 2016 criteria is to enable an early diagnosis and identify the overlapping of these two diseases. ACR- EULAR 2016 criteria is not yet validated for secondary SS and this study is a pioneer in investigating prevalence based on the new criteria.

RESUMO

Abstract Sjogren's syndrome (SS) is an autoimmune disease characterized by lymphocytic infiltration of the exocrine glands and other organs, associated with sicca syndrome but also with systemic involvement with varying degrees of severity. Despite their importance, some systemic manifestations, mainly liver, gastrointestinal, and pancreatic are not routinely evaluated. To address these manifestations, the Sjögren's Syndrome Committee of the Brazilian Society of Rheumatology conducted a broad systematic review of the literature on studies investigating prevalence and diagnosis of these symptoms in Sjogren´s patients and made recommendations based on the findings. Agreement between the experts was achieved using the Delphi method. This is the second part of this guideline, providing 6 recommendations for liver, gastrointestinal, and pancreatic care of SS patients.
