The landscape of systemic lupus erythematosus in Brazil : an expert panel review and recommendations

Purpose: The objective of this review is to address the barriers limiting access to diagnosis and treatment of systemic lupus erythematosus (SLE) and lupus nephritis (LN) in Brazil, specifically for patients in the public healthcare system, arguably those with the least access to innovation. Design: A selected panel of Brazilian experts in SLE/LN were provided with a series of relevant questions to address in a multi-day conference. During the conference, responses were discussed and edited by the entire group through numerous drafts and rounds of discussion until a consensus was achieved. Results: The authors propose specific and realistic recommendations for implementing access to innovative diagnostic tools and treatment alternatives for SLE/LN in Brazil. Moreover, in creating these recommendations, the authors strived to address barriers and impediments for technology adoption. The multidisciplinary care required for SLE/LN necessitates the collective participation of all involved stakeholders. Conclusion: A great need exists to expand the adoption of innovative diagnostic tools and treatments for SLE/LN not only in Brazil but also in most countries, as access issues remain an urgent demand. The recommendations presented in this article can serve as a strategy for new technology adoption in other countries in a similar situation

Brazilian recommendations on the safety and effectiveness of the yellow fever vaccination in patients with chronic immune-mediated inflammatory diseases

Background: In Brazil, we are facing an alarming epidemic scenario of Yellow fever (YF), which is reaching the most populous areas of the country in unvaccinated people. Vaccination is the only effective tool to prevent YF. In special situations, such as patients with chronic immune-mediated inflammatory diseases (CIMID), undergoing immunosuppressive therapy, as a higher risk of severe adverse events may occur, assessment of the risk-benefit ratio of the yellow fever vaccine (YFV) should be performed on an individual level. Main body of the abstract: Faced with the scarcity of specific orientation on YFV for this special group of patients, the Brazilian Rheumatology Society (BRS) endorsed a project aiming the development of individualized YFV recommendations for patients with CIMID, guided by questions addressed by both medical professionals and patients, followed an internationally validated methodology (GIN-McMaster Guideline Development). Firstly, a systematic review was carried out and an expert panel formed to take part of the decision process, comprising BRS clinical practitioners, as well as individuals from the Brazilian Dermatology Society (BDS), Brazilian Inflammatory Bowel Diseases Study Group (GEDIIB), and specialists on infectious diseases and vaccination (from Tropical Medicine, Infectious Diseases and Immunizations National Societies); in addition, two representatives of patient groups were included as members of the panel. When the quality of the evidence was low or there was a lack of evidence to determine the recommendations, the decisions were based on the expert opinion panel and a Delphi approach was performed. A recommendation was accepted upon achieving ≥80% agreement among the panel, including the patient representatives. As a result, eight recommendations were developed regarding the safety of YFV in patients with CIMID, considering the immunosuppression degree conferred by the treatment used. It was not possible to establish recommendations on the effectiveness of YFV in these patients as there is no consistent evidence to support these recommendations. Conclusion: This paper approaches a real need, assessed by clinicians and patient care groups, to address specific questions on the management of YFV in patients with CIMID living or traveling to YF endemic areas, involving specialists from many areas together with patients, and might have global applicability, contributing to and supporting vaccination practices. We recommended a shared decision-making approach on taking or not the YFV

Analysis of cervical dysplasia and woman papillomavirus infection prevalence among women with systemic lupus erythematosus

O lúpus eritematoso sistêmico (LES) que é doença auto-imune com prevalência maior em mulheres, determina lesões potencialmente muito graves em diversos órgãos. Seu tratamento é feito habitualmente com corticosteróides e agentes citostáticos, sendo esses últimos responsáveis não só por um aumento na freqüência de infecções, mas também de neoplasias, principalmente as hematológicas e as relacionadas às infecções virais. Estudos realizados em mulheres com LES, evidenciaram maior incidência de displasias cervicais, principalmente as pré-malignas, contudo poucos, pesquisaram especificamente o papiloma vírus humano (HPV) e sua associação com o uso dos imunossupressores. Considerando que a infecção pelo HPV é a doença sexualmente transmissível de maior prevalência no mundo e, que esse vírus é o agente etiológico do câncer cervical (a segunda neoplasia mais prevalente em mulheres), este estudo foi desenhado com o objetivo de identificar a freqüência da infecção pelo HPV e das displasias cervicais em mulheres com LES incluindo a análise dos fatores de risco clássicos e o uso de imunossupressores. Neste estudo foram selecionadas 177 pacientes com LES e, 244 mulheres sem LES e sem queixas e/ou doenças ginecológicas conhecidas, atendidas no ambulatório de ginecologia do HUPE-UERJ ou da Policlínica Piquet Carneiro-UERJ (grupo controle). Todas as mulheres incluídas, foram previamente informadas e assinaram termo de consentimento livre e esclarecido, aprovado pelo Comitê de Ética em Pesquisa do HUPE-UERJ. A pesquisa do HPV e genotipagem foi feita por reação em cadeia da polimerase e a citopatologia, por coloração de Papanicolaou e análise por dois patologistas. As pacientes com LES apresentaram freqüência da infecção por HPV (20,2%) e de displasias cervicais (22,6%) significativamente mais elevadas que as encontradas no grupo controle (Chi quadrado, P<0,05), apesar de apresentarem em média, menos fatores de risco clássicos para essa infecção (P<0,05). O uso prolongado de imunossupressores, aumentou em três vezes a chance de infecção por HPV dentre as pacientes com LES (cuja prevalência foi de 28,2%). Ainda em referência às pacientes com LES, as que apresentavam HPV, haviam feito uso de doses cumulativas mais altas de ciclofosfamida e de prednisona e também apresentaram maior razão dose-tempo de azatioprina. Em análise multivariada, incluindo pacientes e controles, a história de 3 ou mais parceiros sexuais ao longo da vida e o diagnóstico de LES, determinaram aumento de 2 e 6 vezes respectivamente, na prevalência da infecção por HPV. Essas mesmas variáveis também determinaram um aumento de 3 e 6 vezes na freqüência de displasias cervicais respectivamente. Os resultados obtidos neste estudo demonstram que pacientes com LES, têm maior freqüência de infecção por HPV e de displasias cervicais principalmente das lesões pré-malignas, e que esse aumento de prevalência é ainda mais significativo para as que receberam imunossupresssores por períodos prolongados.Systemic lupus erythematosus (SLE) that is an autoimmune disease with higher prevalence among women, causes potencially severe lesions in different organs. SLE treatment commonly includes the use of steroids and cytostatic agents, being the latter partially responsable for an increased frequency of infection and neoplasia mostly hematologycal and virus-associated cancer. Studies that included women with SLE, have detected higher frequencies of cervical dysplasia, mainly the pre-malignant ones, however few were able to analyse its association with immunosuppressors. Taking into consideration that HPV infection is the most frequent sexually transmitted disease and that this virus is the etiologycal agent of cervical cancer, the second most prevalent neoplasia among women, this study was designed to detect the frequency of HPV infection and cervical dysplasia in SLE patients and to establish its association with classical risk factors and the use of immunosuppressors. We selected 177 SLE patients and 244 women without SLE and who did not present any complain or known gynecological disease who attended to the HUPE-UERJ or Policlínica Piquet Carneiro-UERJ gynecology clinics (control group). All women were previously explained the study and signed an informed consent approved by the HUPE-UERJ Ethical Committee. HPV detection and genotyping were performed by proteinase chain reaction and cytopatology by Papanicolaou technique with analysis by two pathologists. Patients with SLE presented higher frequency of HPV infection and cervical dysplasia than control group (Chi square, P<0.05), despite they presented less frequently the classical HPV associated risk factors (p<0.05). Long-term use of immunosuppressors determined among LSE patients, a three-fold increase on HPV prevalence (28.2%). Also among SLE patients, those who presented HPV, have received higher cumulative doses of cyclophosphamide and prednisone and also had a higher dose-time ratio of azathioprine. Multivariate analysis that included all patients and controls, detected that history of 3 or more life-time sexual partners and the diagnosis of SLE, determined an increase of 2 and 6 times respectively on HPV prevalence. These same variables also determined an increase of 3 and 6 times respectively, on the prevalence of cervical dysplasya. The findings of the present study confirm that SLE patients have higher frequency of HPV infection and cervical dysplasia, mostly the pre-malignant and that it is even more significant for those who received immunosuppressors for long periods

Prevalência do risco para fraturas estimado pela ultra-sonometria óssea de calcâneo em uma população de mulheres brasileiras na pós-menopausa

Observa-se uma forte tendência de envelhecimento da população mundial levando a um aumento da prevalência de doenças como a osteoporose e fraturas. O objetivo deste estudo foi determinar a prevalência de risco para fraturas estimado pela ultra-sonometria óssea de calcâneo em uma população de mulheres na pós-menopausa, residentes na Ilha de Paquetá, Rio de Janeiro, Brasil. Realizamos medidas antropométricas e ultra-sonometria óssea de calcâneo com aparelho Sonost 2000 em 385 mulheres pós-menopausadas. Observamos que 59,22% da amostra apresentava T-score < -1, sendo que 16,88% tinham T-score < -2,5. Houve variação em todos os parâmetros do exame conforme o aumento da idade, e diferença estatisticamente significativa (p < 0,05) entre os grupos de risco para fratura por idade, tempo de menopausa, peso, IMC e percentual de gordura corpórea. Houve correlação entre velocidade do som e IMC (r = 0,155; p = 0,002). Concluímos que cerca de 60% da população feminina estudada apresenta algum grau de risco para fraturas. As mulheres do grupo de maior risco (T-score < -2,5) eram mais velhas, com maior tempo de menopausa, maior peso e IMC do que as dos outros grupos

This study aimed to determine the prevalence of fracture risk, estimated by quantitative ultrasound of the calcaneus in a population of postmenopausal women residing in the Ilha de Paquetá neighborhood of Rio de Janeiro, Brazil. We conducted anthropometric measurements and quantitative ultrasound of the calcaneus using Sonost 2000 in 385 postmenopausal women. Some 59.22% of the sample showed a T-score < -1, while 16.88% had T-score < -2.5. The test parameters varied with increasing age, with a statistically significant difference (p < 0.05) between fracture risk groups according to age, time since menopause, weight, BMI, and body fat. There was a correlation between sound velocity and BMI (r = 0.155; p = 0.002). We concluded that some 60% of the female study population showed some degree of fracture risk. The women at highest risk (T-score < -2.5) were older, with more time since menopause, and had higher weight and BMI as compared to the other groups

Polymorphisms in NAT2 (N-acetyltransferase 2) gene in patients with systemic lupus erythematosus

ABSTRACT Objective: To investigate potential associations of four substitutions in NAT2 gene and of acetylator phenotype of NAT2 with systemic lupus erythematosus (SLE) and clinical phenotypes. Methods: Molecular analysis of 481C>T, 590G>A, 857G>A, and 191G>A substitutions in the NAT2 gene was performed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique, from DNA extracted from peripheral blood samples obtained from patients with SLE (n = 91) and controls (n = 97). Results and conclusions: The 857GA genotype was more prevalent among nonwhite SLE patients (OR = 4.01, 95% CI = 1.18-13.59). The 481T allele showed a positive association with hematological disorders that involve autoimmune mechanisms, specifically autoimmune hemolytic anemia or autoimmune thrombocytopenia (OR = 1.97; 95% CI = 1.01-3.81)

Anal Cancer in Systemic Lupus Erythematosus Patients is a Neglected Condition

Patients with systemic lupus erythematosus have a higher incidence of neoplasms associated with human papillomavirus infections, such as those that affect the vulva, the vagina, and the cervix; however, little is known about the frequency of anal cancer among these patients. Although there are recommendations for screening for this cancer in immunosuppressed individuals, it is possible that this procedure is not strictly followed. We describe the case of a 47-year-old woman with systemic lupus erythematosus who was treated with immunosuppressants and developed advanced anal squamous cell carcinoma after adequate treatment and healing of a high-grade cervical squamous intraepithelial lesion. Five years after the completion of the anal cancer treatment, the patient presented with cystic hepatic lesions that were histopathologically confirmed to be metastatic squamous cell carcinoma. This report aimed to highlight the need for anal cancer screening in patients with lupus, particularly if there was a history of cervical cytopathological alterations
