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.

Este trabalho avalia prescrições médicas aviadas em farmácias de unidades de saúde da Secretaria Municipal de Saúde de Belo Horizonte (SMS-BH), Brasil. Foram analisadas 4.607 prescrições, no período de março a abril de 1999, agrupadas segundo sua origem. A análise enfocou informações que deveriam constar em uma prescrição médica. Os principais resultados encontrados foram: (a) número médio de 2,4 medicamentos/prescrição para os dois grupos; (b) prescrição de quatro ou mais medicamentos em 18,0% das prescrições internas e 17,6% das externas; (c) ausência de recomendações de uso em 84,3% das prescrições internas e 85,5% nas externas; (d) presença de dados posológicos variando de 51,2% a 97,6% nas prescrições internas e de 57,9% a 96,5% nas externas; (e) utilização do nome genérico para todos os medicamentos em 51,9% nas prescrições internas e 28,4% nas externas e (f) prescrição com todos os medicamentos padronizados pela SMS-BH em 88,7% das internas e 76,4% das externas. A análise dos dados demonstra necessidade de educação continuada dos prescritores e adoção de outras medidas para melhoria da qualidade de prescrições, na perspectiva de promover o uso racional de medicamentos.

This article focuses on medical prescriptions dispensed at health centers under the Municipal Health Department in Belo Horizonte, Minas Gerais State, Brazil. The study analyzed 4,607 prescriptions from March to April 1999, grouped according to origin (internal or external). The analysis focused on information written on medical prescriptions. The main findings were: (a) an average of 2.4 drugs per prescription in both groups; (b) prescriptions filled out with 4 or more drugs accounted for 18.0% of internal and 17.6% of external prescriptions; (c) 84.3% of internal and 85.5% of external prescriptions provided no instructions for use of medication; (d) information on dosage regimen varied from 51.2% to 97.6% for internal and 57.9% to 96.5% for external prescriptions; (e) generic names were specified for 51.9% and 28.4% of all drugs on internal and external prescriptions, respectively; (f) prescriptions containing standard drugs from the Municipal Health Department accounted for 88.7% of internal and 76.4% of external prescriptions. Data analysis shows the need for continuing education of physicians and adoption of other methods to improve quality of prescriptions and promote rational use of drugs.
