ABSTRACT
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.
ABSTRACT
PURPOSE: To describe the procedures used in developing Clinical and Regulatory Protocols for primary care teams to use in the management of the most common scenarios of impaired vision in Southern Brazil. METHODS: A retrospective review of 1.333 referral forms from all primary care practitioners was performed in Ribeirão Preto city, during a 30-day period. The major ophthalmic diagnostic categories were evaluated from those referrals forms. The Clinical and Regulatory Protocols development process was held afterwards and involved scientific cooperation between a university and the health care system, in the form of workshops attended by primary care practitioners and regulatory system team members composed of health care administrators, ophthalmologists, and professors of ophthalmology and social medicine. RESULTS: The management of impaired vision was chosen as the theme, since it accounted for 43.6 percent of the ophthalmology-related referrals from primary care providers of Ribeirão Preto. The Clinical and Regulatory Protocols developed involve distinctive diagnostic and therapeutic interventions that can be performed at the primary care level and in different health care settings. The most relevant clinical and regulatory interventions were expressed as algorithms in order to facilitate the use of the Clinical and Regulatory Protocols by health care practitioners. CONCLUSIONS: These Clinical and Regulatory Protocols could represent a useful tool for health systems with universal access, as well as for health care networks based on primary care and for regulatory system teams. Implementation of these Clinical and Regulatory Protocols can minimize the disparity between the needs of patients with impaired vision and the treatment modalities offered, resulting in a more cooperative health care network.
OBJETIVO: Descrever os procedimentos utilizados no desenvolvimento de Protocolos Clínicos e de Regulação, para equipes de atenção primária à saúde, voltados à condução dos cenários clínicos mais comuns de dificuldade visual observados na região sudeste do Brasil. MÉTODOS: Realizou-se a revisão retrospectiva de 1.333 guias de encaminhamento advindas de todos os profissionais da atenção primária da cidade de Ribeirão Preto, durante um período de 30 dias. As principais categorias diagnósticas oftalmológicas foram avaliadas nessas guias de referência. O processo de desenvolvimento dos Protocolos Clínicos e de Regulação ocorreu na sequência e envolveu a cooperação científica entre a universidade e o sistema de saúde, sob a forma de oficinas com médicos da atenção primária e membros da equipe do sistema de regulação, composto por gestores de saúde, oftalmologistas, além de professores de oftalmologia e medicina social. RESULTADOS: A dificuldade visual foi escolhida como tema central, uma vez que representou 43,6 por cento dos encaminhamentos oftalmológicos advindos de serviços de atenção primária de Ribeirão Preto. Os Protocolos Clínicos e de Regulação desenvolvidos envolveram diferentes procedimentos diagnósticos e terapêuticos que podem ser executados na atenção primária e outros níveis ou contextos de cuidados à saúde. As intervenções clínicas e de encaminhamento mais relevantes foram expressas como algoritmos, a fim de facilitar a utilização do protocolo pelos profissionais da saúde. CONCLUSÕES: Os Protocolos Clínicos e de Regulação poderão representar uma ferramenta útil para os sistemas de saúde que contam com acesso universal, bem como para as redes de cuidados de saúde baseadas na atenção primária e nos sistemas de regulação. A implementação de Protocolos Clínicos e de Regulação poderá minimizar a disparidade entre as necessidades dos pacientes com dificuldade visual e as formas de condução de casos oftalmológicos, resultando em uma rede de saúde mais eficiente.
