Introduction: systemic lupus erythematosus (SLE) is known as a multisystem autoimmune disease, whose cause is unknown, and is characterized by the presence of immune complexes and autoantibodies. In international series, presentation of infectious processes is described in these patients in up to 75 % of cases. Infections occur both at the beginning of the disease and in late stages, and are a direct cause of death in 30 % to 60 % of patients. Cases and reason for hospitalization up to 30 %. Objectives: determine the most frequent infectious processes in patients with systemic lupus erythematosus admitted to the Medical Clinic Service of the Hospital Nacional in the period 2022-2023. Methodology: observational, descriptive cross-sectional design of patients with a diagnosis of systemic lupus erythematosus according to criteria of European League Against Rheumatism (EULAR)-2019 who are admitted to the Medical Clinic service of the Hospital Nacional (Itauguá-Paraguay) in the period of 2022-2023. Results: the average age of the patients was 34 years, with a predominance of the female sex in 88.18 %. Respiratory system infections were the most frequently diagnosed in 50 (45.45 %) patients, followed by urinary tract infection in 47 (42.38 %) patients. The predominant risk factor was the use of corticosteroids in a total of 105 (96.40 %) patients, it was established in a total of 97 (88.18 %) patients with antibiotic therapy, within the demographic aspect of the urban area 56 (50.90 %) patients and rural 54 (49.1 %). Conclusion: respiratory tract infection was the most frequent infection, the predominant risk factor is the use of corticosteroids and they received antibiotic therapy, which in monotherapy was the most used.

IL-1β and IL-17 in cutaneous lupus erythematous skin biopsies: could immunohistochemicals indicate a tendency towards systemic involvement?

Abstract Background: Only a fraction of patients with cutaneous lupus erythematosus (CLE) will eventually progress toward systemic disease (SLE). Objective: To find inflammatory biomarkers which could predict the progression of cutaneous lupus erythematosus (CLE) into systemic lupus erythematosus (SLE) using immunohistochemical (IHC) assays. Methods: Immunohistochemical markers for cytotoxic, inflammatory, and anti-inflammatory responses and morphometric methods were applied to routine paraffin sections of skin biopsies, taken from lesions of 59 patients with discoid lupus, subacute lupus, and lupus tumidus. For the diagnosis of SLE, patients were classified by both the American College of Rheumatology (ACR-82) and the Systemic Lupus International Collaborating Clinics (SLICC-12) systems. Results: Skin samples from CLE/SLE +patients presented higher expression of IL-1β (ARC-82: p = 0.024; SLICC-12: p = 0.0143) and a significantly higher number of cells marked with granzyme B and perforin (ARC: p = 0.0097; SLICC-12: p = 0.0148). Biopsies from CLE/SLE- individuals had higher expression of IL-17 (ARC-82: p = 0.0003; SLICC-12: p = 0.0351) and presented a positive correlation between the density of granzyme A+and FoxP3+ cells (ARC-82: p = 0.0257; SLICC-12: p = 0.0285) and CD8+ cells (ARC-82: p = 0.0075; SLICC-12: p = 0.0102), as well as between granulysin-positive and CD8+ cells (ARC-82: p = 0.0024; SLICC-12: p = 0.0116). Study limitations: Patients were evaluated at a specific point in their evolution and according to the presence or not of systemic disease. The authors cannot predict how many more, from each group, would have evolved towards SLE in the following years. Conclusions: In this cohort, immunohistochemical findings suggested that patients with a tendency to systemic disease will show strong reactivity for IL-1β, while those with purely cutaneous involvement will tend to express IL-17 more intensely.

Evaluation of core decompression outcome in systemic lupus erythematosus with hip osteonecrosis: a retrospective cohort study

Abstract Background Osteonecrosis is a major cause of morbidity for patients with systemic lupus erythematosus (SLE). Although core decompression is an approved and trusted technique to prevent further joint deterioration, this surgical method seems to be less beneficial for SLE patients. We aimed to evaluate the outcomes of core decompression in SLE patients with primary stages of femoral head osteonecrosis. Methods In this study, 23 patients (39 affected hip joints) with osteonecrosis of the femoral head with stage II of the disease, based on the Ficat-Arlet classification system, underwent core decompression. Also, patients demographic characteristics, clinical data, medication history, comorbidities, immunological findings, hip plain radiographs, history of total hip arthroplasty after core decompression, and patients satisfaction with joint function according to the Oxford hip score questionnaire were obtained. Results In the study, 53.8% of affected joints showed signs of radiographic deterioration in follow-up imaging. Sixty-one and a half percent (61.5%) of patients had unsatisfactory joint performance. A third (33.3%) of affected hip joints underwent total hip arthroplasty up to 5 years from core decompression. SLE patients with a history of receiving bisphosphonate were 83.2% less dissatisfied with their joint function than patients without a history of bisphospho-nate use (P < 0.02). Of the 23 studied cases, the mean cumulative dose of prednisolone before and after core decompression surgery was 46.41 mg and 14.74 mg respectively. Besides, one case (2.6%) that had a high anti-phospholipid antibodies level during follow-up did not have any radiographic deterioration, and 9 cases (23.1%) had some degrees of radiographic deterioration. Conclusions The patients group that used bis-phosphonate, had a higher level of satisfaction with joint function after core decompression. Patients with high-level anti-phospholipid antibodies are related to a poor prognosis after core decompression.

What is known about the effects of vitamin D in neuropsychiatric lupus?

Abstract Systemic lupus erythematosus (SLE) is an autoimmune disease that can affect several organs and systems. The central and/or peripheral nervous system can suffer from complications known as neuropsychiatric lupus (NPSLE). Studies have associated the manifestations of SLE or NPSLE with vitamin D deficiency. It has been shown that hypovitaminosis D can lead to cognition deficits and cerebral hypoperfusion in patients with NPSLE. In this review article, we will address the main features related to vitamin D supplementation or serum vitamin D levels with neuropsychiatric manifestations, either in patients or in animal models of NPSLE.

Continuous Unilateral Cephalalgia Due to Systemic Lupus Erythematosus: A Case Report / Cefaleia unilateral contínua por lúpus eritematoso sistêmico: relato de caso

BACKGROUND: Hemicrania continua is a rare form of cephalalgia featuring a chronic and persistent headache in only one side of the head. OBJECTIVES: In this report, we present a case of a patient with hemicrania continua and systemic lupus erythematosus (SLE). METHODS: We collected patient data through the electronic medical record. Afterward, we reviewed the literature regarding hemicrania continua and its pathophysiology and correlation with neurovascular alterations, inflammation, and SLE. RESULTS: A 42-year-old woman visited the emergency department due to worsening constant unilateral cephalalgia that had been present for the past 6 months. The patient reported a highly intense (10/10) headache in the entire left hemicrania that radiated to the left shoulder. During physical examination, she presented with nystagmus, vertigo, and aggravated cephalalgia associated to body movement and, despite having no optic nerve thickening. In addition, she had jaundice, tachycardia, and splenomegaly. Complimentary exams found deep anemia, depletion in complement system and anti-nuclear factors, suggesting a possible hemolytic anemia (AIHA) due to SLE. Treatment was initiated with hydrocortisone and prednisone, associated with amitriptyline, fluoxetine and diazepam, reaching full remission. CONCLUSION: These syndromes have aggravated each other, and possibly the explanation for the cephalalgia remission was the control of AIHA and SLE. It features a rare case in literature and thus warrants discussion.

INTRODUÇÃO: Hemicrania contínua é uma forma rara de cefaléia caracterizada por cefaleia crônica e persistente em apenas um lado da cabeça. OBJETIVOS: Neste relato apresentamos o caso de um paciente com hemicrania contínua e lúpus eritematoso sistêmico (LES). MÉTODOS: Coletamos dados dos pacientes por meio do prontuário eletrônico. Posteriormente, revisamos a literatura sobre a hemicrania contínua e sua fisiopatologia e correlação com alterações neurovasculares, inflamação e LES. RESULTADOS: Uma mulher de 42 anos recorreu ao serviço de urgência devido ao agravamento da cefaleia unilateral constante, presente nos últimos 6 meses. O paciente relatou cefaleia de alta intensidade (10/10) em toda a hemicrânia esquerda com irradiação para o ombro esquerdo. Ao exame físico apresentava nistagmo, vertigem e cefaléia agravada associada à movimentação corporal e, apesar de não apresentar espessamento do nervo óptico. Além disso, ela apresentava icterícia, taquicardia e esplenomegalia. Os exames complementares evidenciaram anemia profunda, depleção do sistema complemento e fatores antinucleares, sugerindo uma possível anemia hemolítica (AIHA) por LES. Iniciou-se tratamento com hidrocortisona e prednisona, associadas a amitriptilina, fluoxetina e diazepam, atingindo remissão completa. CONCLUSÃO: Essas síndromes agravaram-se mutuamente e possivelmente a explicação para a remissão da cefaléia foi o controle da AIHA e do LES. Apresenta um caso raro na literatura e, portanto, merece discussão.

Severe Hypocalcemia as an Atypical Manifestation of Seronegative Celiac Disease in a Patient with Systemic Lupus Erythematosus: Case Report

Aim: To describe the clinical picture and diagnosis of an episode of severe hypocalcemia in a patient with systemic lupus erythematosus (SLE) in remission, with chronic diarrhea that led to the diagnosis of celiac disease (CD). Case presentation: 22-year-old patient, diagnosed with SLE at age 10, in remission. He consulted for a two-month history of paresthesias, muscle spasms, myalgias, and episodes of tetany in the previous week, associated with malabsorptive postprandial diarrhea. His laboratory tests showed severe hypocalcemia, vitamin D deficiency, severe hypomagnesemia, and mild hypokalemia. In the study for CD, serology reported normal anti-tissue transglutaminase IgA, antigliadin IgA, and IgG and low total IgA levels. Enteroscopy revealed erosive bulbo-duodenitis, with villous atrophy and increased intraepithelial lymphocytes in the pathology, which, together with the immunohistochemical study, allowed the diagnosis of CD, Marsh 3a type. Management was initiated with a gluten-free diet, with a positive clinical response. Conclusion: CD should be suspected in patients with SLE who present with diarrhea, abdominal pain, nausea/vomiting, recurrent oral aphthosis, and anemia. In rare seronegative CD cases, other causes of villous atrophy, mainly infectious, toxic, and immunological, must be ruled out. There is an association between CD and SLE, so diagnosis must be early and timely with the best testing scheme available to achieve effective treatment before complications occur.

Objetivo: Describir la presentación clínica y diagnóstico de un episodio de hipocalcemia grave en un paciente con lupus eritematoso sistémico (LES) en remisión, con diarrea crónica que condujo al diagnóstico de enfermedad celíaca (EC). Presentación del caso: Paciente de 22 años, con diagnóstico de LES a los 10 años, en remisión. Consultó por 2 meses de evolución de parestesias, espasmos musculares, mialgias y episodios de tetania en la semana previa, asociado a diarrea posprandial malabsortiva. Sus laboratorios mostraron hipocalcemia grave, déficit de vitamina D, hipomagnesemia grave e hipopotasemia leve. En el estudio para EC la serología reportó antitransglutaminasa tisular IgA, antigliadina IgA e IgG normales y niveles de IgA total bajos. La enteroscopia evidenció bulboduodenitis erosiva, con atrofia de las vellosidades y aumento de linfocitos intraepiteliales en la patología, que junto al estudio inmunohistoquímico permitieron concluir el diagnóstico de EC, tipo Marsh 3a. Se inició el manejo con una dieta libre de gluten, con una respuesta clínica positiva. Conclusión: La EC debe sospecharse en pacientes con LES que inicien con diarrea, dolor abdominal, náuseas/vómitos, aftosis oral recurrente y anemia. En los casos de EC seronegativa, los cuales son poco comunes, se deben descartar otras causas de atrofia de las vellosidades principalmente infecciosas, tóxicas e inmunitarias. Existe una asociación entre EC y LES, por lo cual el diagnóstico debe ser precoz y oportuno con el mejor esquema de pruebas disponible para lograr realizar un tratamiento efectivo antes de que se presenten las complicaciones.

Linfadenopatías generalizadas como manifestación inicial de lupus eritematoso sistémico: a propósito de un caso clínico

La presencia de linfadenopatías generalizadas se ha asociado de forma usual con lupus eritematoso sistémico (LES), sin embargo, no es usual encontrar este hallazgo como manifestación inicial de la enfermedad. Existen múltiples diagnósticos diferenciales que incluyen la linfadenitis necrotizante histiocítica de Kikuchi, la enfermedad de Castleman, infecciones y el linfoma cuando se presenta este hallazgo como síntoma inicial de LES. Presentamos el caso de un hombre de 56 años que se presentó con 2 meses de linfadenopatía generalizada sin datos al examen o antecedentes que sugirieran diagnóstico de LES; se sospechó inicialmente linfoma o enfermedad infecciosa y se realizó un estudio exhaustivo incluido biopsia de ganglio cervical. La investigación de laboratorio finalmente reveló leucopenia, proteinuria significativa, ANA y anti-dsDNA positivos e hipocomplementemia, lo que confirma el diagnóstico de enfermedad autoinmune tipo LES. Este caso ilustra la importancia de reconocer esta forma de presentación inusual, dado que se trata de una enfermedad potencialmente fatal.

The presence of generalized lymphadenopathy has usually been associated with systemic lupus erythematosus (SLE), however, it is not usual to find this finding as an initial manifestation of the disease. There are multiple differential diagnoses that include Kikuchi histiocytic necrotizing lymphadenitis, Castleman disease, infections and lymphoma when this finding is presented as an initial symptom of SLE. We present the case of a 56-year-old man who presented with 2 months of generalized lymphadenopathy without examination findings or history suggesting a diagnosis of SLE; Lymphoma or infectious disease was initially suspected and an exhaustive study was performed, including cervical lymph node biopsy. Laboratory investigation finally revealed leukopenia, significant proteinuria, positive ANA, positive anti-dsDNA, and hypocomplementemia, confirming the diagnosis of SLE-type autoimmune disease. This case illustrates the importance of recognizing this unusual presentation, given that it is a potentially fatal disease.

Fascitis necrotizante asociada a esteatohepatitis en el curso del lupus eritematoso sistémico / Necrotizing Fasciitis Associated with Steatohepatitis in The Course of Systemic Lupus Erythematosus

Introducción: La fascitis necrotizante es un cuadro muy grave causado por una infección bacteriana de la piel y de tejidos blandos subcutáneos, cuya evolución es hacia la destrucción y necrosis de los tejidos en un corto espacio de tiempo; el lupus eritematoso sistémico es una enfermedad autoinmune de causa desconocida que quienes la padecen tienen una mayor probabilidad de contraer infecciones debido al mal funcionamiento del sistema inmunológico y/o los efectos secundarios causados por los medicamentos. Objetivo: Observar la importancia de un tratamiento rápido y eficaz de la fascitis necrotizante en un paciente con lupus eritematoso sistémico y esteatohepatitis no alcohólica. Presentación de caso: Se presentó el caso clínico de un paciente de 30 años con diagnóstico de lupus eritematoso sistémico que desarrolló de forma concomitante de fascitis necrotizante y esteatohepatitis no alcohólica. A pesar de un tratamiento adecuado, el paciente fue agresivo. Tuvo una estadía hospitalaria de 83 días, con una evolución desfavorable que conllevó a la muerte(AU)

Introduction: Necrotizing fasciitis is a very serious condition caused by a bacterial infection of the skin and subcutaneous soft tissues, whose evolution is towards the destruction and necrosis of the tissues in a short space of time; Systemic lupus erythematosus is an autoimmune disease of unknown cause that sufferers are more likely to contract infections due to poor immune system function and/or side effects caused by medications. Objective: To observe the importance of rapid and effective treatment of necrotizing fasciitis in a patient with systemic lupus erythematosus and non-alcoholic steatohepatitis. Case report: We report the clinical case of a 30-year-old patient diagnosed with systemic lupus erythematosus who concomitantly developed necrotizing fasciitis and nonalcoholic steatohepatitis. Despite adequate treatment, the patient was aggressive. The patient had a hospital stay of 83 days, with an unfavorable evolution that led to his death(AU)

Anti-C1q como Marcador de Nefritis Lúpica / Anti-C1q as Lupus Nephritis Marker

Introducción: Los autoanticuerpos anti-C1q han sido propuestos como un marcador útil en el lupus eritematoso sistémico por su asociación con la nefritis lúpica. Objetivo: Determinar la prevalencia de anti-C1q en pacientes con lupus eritematoso sistémico y otras enfermedades reumáticas para la evaluar la asociación con la nefropatía lúpica. Métodos: Se incluyeron 179 pacientes con lupus eritematoso sistémico y 82 con otras enfermedades reumáticas. La nefritis lúpica fue diagnosticada en 70 (39 por ciento) de los pacientes con lupus eritematoso sistémico. Los anticuerpos anti-C1q IgG se determinaron por ELISA. Las asociaciones se evaluaron por análisis de regresión logística. Resultados: La prevalencia de anti-C1q fue de 37 poe ciento (66/179) en los pacientes con lupus eritematoso sistémico y de 9 por ciento (7/82) en controles (OR = 6,3; IC 95 por ciento 2,8-14,1; p < 0,001). El anti-C1q fue asociado con proteinuria (OR = 2,6; IC 95 por ciento 1,2-6,0; p < 0,022); eritrosedimentación elevada (OR = 3,2; IC 95 por ciento 1,5-6,7; p < 0,003) y anti-DNAdc (OR = 3,9; IC 95 por ciento 1,7-9,1; p < 0,002). En el modelo de regresión logística ajustado para demografía y anti-DNAdc, aunque la OR del anti-C1q para la nefritis fue 2 veces más alta que en ausencia del anti-C1q, solo se aproximó a la significación estadística. La positividad simultánea de anti-C1q y anti-DNAdc estuvo asociada a la nefritis lúpica (OR = 4,3; IC 95 por ciento 1,9-9,5; p < 0,001). Conclusiones: El anti-C1q se presentó con mayor frecuencia en pacientes con lupus eritematoso sistémico que en los controles. El anti-C1q combinado con anti-DNAdc resultó fuertemente asociado a la nefritis lúpica(AU)

Introducción: Anti-C1q autoantibodies have been proposed as useful marker in systemic lupus erythematosus due to their association with lupus nephritis. Objective: To determine the prevalence of anti-C1q in patients with systemic lupus erythematosus and other rheumatic diseases to evaluate the association with lupus nephropathy. Methods: One hundred seventy-nine patients with systemic lupus erythematosus and 82 with other rheumatic diseases were included. Lupus nephritis was diagnosed in 70 (39percent) of patients with systemic lupus erythematosus. Anti-C1q IgG antibodies were determined by ELISA. Associations were evaluated by logistic regression analysis. Results: The prevalence of anti-C1q was 37percent (66/179) in patients with systemic lupus erythematosus and 9percent (7/82) in controls (OR = 6.3; 95percent CI 2.8-14). .1; p < 0.001). Anti-C1q was associated with proteinuria (OR = 2.6; 95percent CI 1.2-6.0; p < 0.022); elevated erythrocyte sedimentation rate (OR = 3.2; 95percent CI 1.5-6.7; p < 0.003) and anti-dsDNA (OR = 3.9; 95percent CI 1.7-9.1; p < 0.002). In the logistic regression model adjusted for demographics and anti-dsDNA, although the OR of anti-C1q for nephritis was 2-fold higher than in the absence of anti-C1q, it only approached statistical significance. Simultaneous positivity of anti-C1q and anti-dsDNA was associated with lupus nephritis (OR = 4.3; 95percent CI 1.9-9.5; p < 0.001). Conclusions: Anti-C1q occurred more frequently in patients with systemic lupus erythematosus than in controls. Anti-C1q combined with anti-dsDNA was strongly associated with lupus nephritis(AU)

Role of HLA alleles polymorphism in systemic lupus erythematosus: A prospective study from North India

Background: Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder and has complex etiopathogenesis. The most appropriate hypothesis states that genetic susceptibility in the presence of environmental risk factors predisposes to SLE. HLA class II alleles are critical to immune response and are highly polymorphic. Various alleles in HLA-DR and -DQ regions were analyzed in SLE patients and healthy controls to see their role in susceptibility or protection to SLE. Materials and Methods: This was a prospective observational study, in which a total of 100 SLE patients and 100 controls were analyzed. HLA typing was done by polymerase chain reaction (PCR)-sequence-specific oligonucleotide (SSO) method (SSO probe). Results: DR?1*0301 was significantly increased in SLE patients when compared to controls and had the highest odds ratio. Other risk factor alleles found to be increased were DR?1*0701, DQ?1*0202, and DQ?1*0301, which had a significant positive association with SLE, suggesting their role in susceptibility to SLE. In contrast, DR?1*0401, DR?1*1401, DR?1*1404, DR?1*1501, DQ?1*0501, and DQ?1*0201 showed statistically significant reduction in SLE patients, while these were much more common in controls, suggesting their protective role. Conclusion: This study is only the second study in patients from North India and it determines the role of DR?1*0301, DR?1*0701, DQ?1*0202, and DQ?1*0301 alleles as risk factors in SLE patients.

Kikuchi–Fujimoto disease: A rare cause of cervical lymphadenopathy

Kikuchi–Fujimoto disease (KFD), also known as histiocytic necrotizing lymphadenitis, is a rare and generally self-limiting disease of uncertain etiology that presents with fever and cervical lymphadenopathy in both the pediatric and adult populations. Here, we present the case of a 5-year-old male who presented with acute onset of fever and cervical lymphadenopathy which was initially diagnosed and managed as staphylococcal lymphadenitis. He underwent an excisional biopsy when symptoms persisted, which confirmed the diagnosis of KFD and was managed conservatively. This case study emphasizes awareness of this entity in the differential diagnosis of fever with persistent lymphadenopathy. Due to its characteristic overlap with other disorders such as tuberculous lymphadenitis, and lymphoma, KFD remains an arduous diagnosis for physicians. Therefore, awareness about its symptoms helps in minimizing potentially harmful unnecessary evaluations and thereby preventing misdiagnosis and inappropriate treatment.

Emphysematous pyelonephritis in patient with hemophagocytic lymphohistiocytosis: A case report

Emphysematous pyelonephritis (EPN) and hemophagocytic lymphohistiocytosis (HLH) are rare, fatal illnesses. The presence of both at once in a patient is extremely rare. The number of reported cases of EPN is <800 cases worldwide to date. Contrarily, the prevalence of adults with HLH is estimated to be 1 in every 2000 adults admitted to a tertiary health center. This case report aims to present the case of a 45-year-old woman who was diagnosed with EPN with a history of HLH and was successfully treated with medication alone. In conclusion, the clinical manifestations of EPN are non-specific and need imaging modalities like computed tomography (CT) scans. Treating EPN is based on CT scan classification. Medical treatment was an option for these patients. There is no direct association between EPN and HLH; it is a challenging decision to treat patients with both.

Cutaneous lupus erythematosus: a review of etiopathogenic, clinical, diagnostic and therapeutic aspects

Abstract Cutaneous lupus erythematosus is an autoimmune disease of varied clinical expression, which may present as an exclusively cutaneous disease or be one of the multiple manifestations of systemic lupus erythematosus. Its classification includes acute, subacute, intermittent, chronic and bullous subtypes, which are usually identified based on clinical features and histopathological and laboratory findings. Other non-specific cutaneous manifestations may be associated with systemic lupus erythematosus and are usually related to disease activity. Environmental, genetic and immunological factors play a role in the pathogenesis of skin lesions in lupus erythematosus. Recently, considerable progress has been made in elucidating the mechanisms involved in their development, which allows for foreseeing future targets for more effective treatments. This review proposes to discuss the main etiopathogenic, clinical, diagnostic and therapeutic aspects of cutaneous lupus erythematosus, aiming to update internists and specialists from different areas.

Climatério e lúpus eritematoso sistêmico / Climacteric and systemic lupus erythematosus

O lúpus eritematoso sistêmico é uma doença crônica, complexa e multifatorial que apresenta manifestações em vários órgãos. O seu acometimento ocorre 10 vezes mais no sexo feminino do que no masculino. É uma doença com uma clínica variada e com graus variados de gravidade, causando fadiga, manifestações cutâneas, como rash malar, fotossensibilidade, queda de cabelo e manifestações musculoesqueléticas, como artralgia, mialgia e atrite. Podem ocorrer flares (crises), que se caracterizam por aumento mensurável na atividade da doença. No climatério, no período da pré-menopausa, o lúpus eritematoso sistêmico ocorre com mais frequência, podendo ocorrer também na pós-menopausa. Algumas doenças são mais frequentes na fase do climatério, e a presença do lúpus pode influenciar na sua evolução, como a doença cardiovascular, osteoporose e tromboembolismo venoso. A terapia hormonal oral determina aumento do risco de tromboembolismo venoso no climatério, e na paciente com lúpus eritematoso sistêmico há aumento dos riscos de flares e de trombose. Em vista disso, a terapia hormonal é recomendada apenas para pacientes com lúpus eritematoso sistêmico estável ou inativo, sem história de síndrome antifosfolípides e com anticorpos antifosfolípides negativa, devendo-se dar preferência para a terapia estrogênica transdérmica, em menor dose e de uso contínuo. Na paciente com lúpus eritematoso sistêmico ativo ou com história de síndrome antifosfolípides ou com anticorpos antifosfolípides positiva, recomenda-se a terapia não hormonal, como os antidepressivos.

Systemic lupus erythematosus is a chronic, complex, multifactorial disease that manifests in several organs. Its involvement occurs 10 times more in females than in males. It is a disease with a varied clinic and varying degrees of severity, causing fatigue, skin manifestations such as malar rash, photosensitivity, hair loss and musculoskeletal manifestations such as arthralgia, myalgia and arthritis. Flare may occur, which are characterized by measurable increase in disease activity. In the climacteric, in the premenopausal period, systemic lupus erythematosus occurs more frequently, and may also occur in the postmenopausal period. Some diseases are more frequent in the Climacteric phase and the presence of lupus can influence its evolution, such as cardiovascular disease, osteoporosis and venous thromboembolism. Oral hormone therapy determines an increased risk of venous thromboembolism in the climacteric and in patients with systemic lupus erythematosus there is an increased risk of flares and thrombosis. In view of this, hormone therapy is only recommended for patients with stable or inactive systemic lupus erythematosus, without a history of antiphospholipid syndrome and with antiphospholipid antibodies, giving preference to transdermal estrogen therapy, at a lower dose and for continuous use. In patients with active systemic lupus erythematosus or with a history of antiphospholipid syndrome or positive antiphospholipid antibodies, non-hormonal therapy, such as antidepressants, is recommended.

Vitamina D y su relación con la actividad en pacientes con lupus eritematoso sistémico

Introducción: Existe una serie de estudios sobre el lupus eritematoso sistémico y vitamina D, que relacionan su deficiencia y varios aspectos clínicos. Se ha postulado que es uno de los factores ambientales que puede desencadenar la autoinmunidad. Objetivo: Evaluar los niveles séricos de vitamina D en un grupo de pacientes con lupus eritematoso sistémico y su relación con la actividad de la enfermedad. Métodos: Se realizó un estudio descriptivo transversal en 75 pacientes con diagnóstico de lupus eritematoso sistémico, se revisaron los expedientes clínicos, se registraron las variables sexo, raza, edad, manifestaciones clínicas, niveles de vitamina D en sangre y se midió la actividad de la enfermedad mediante el instrumento SLEDAI. Resultados: Predominó el sexo femenino (88 %), el grupo etario de 40 a 49 años de mayor porcentaje (26,7 %) y la raza blanca (73,3 %). Se demostró la insuficiencia de vitamina D (60 %) con una media de 38,5 y desviación típica de 8,5; las alteraciones de laboratorio que se presentaron con mayor frecuencia fueron leucocituria (52 %) y hematuria (33,3 %). Se relacionó la actividad leve y moderada (60 %) y la insuficiencia de vitamina D (62,2 %). No se evidenció asociación estadística significativa entre los niveles de actividad elevados y los niveles de vitamina D. Conclusiones: Se evaluaron los niveles séricos de vitamina D, resultó que las mujeres blancas con la enfermedad presentaron niveles bajos de vitamina D y actividad de la enfermedad, aunque no se demostró asociación significativa.

Introduction: There are a number of studies on systemic lupus erythematosus and vitamin D, which relate its deficiency and various clinical aspects. It has been postulated that it is one of the environmental factors that can trigger autoimmunity. Objective: To evaluate the serum levels of vitamin D in a group of patients with systemic lupus erythematosus and the relationship with the activity of the disease. Methods: A descriptive cross-sectional study was carried out in 75 patients diagnosed with systemic lupus erythematosus, the clinical records were reviewed. The variables sex, race, age, clinical manifestations, vitamin D levels in blood were recorded, and disease activity was measured using the SLEDAI instrument. Results: The female sex (88%), the age group from 40 to 49 years with the highest percentage (26.7%) and the white race (73.3%) predominated. Vitamin D insufficiency was demonstrated (60%) with a mean of 38.5 and a standard deviation of 8.5; the most frequent laboratory abnormalities were leukocyturia (52%) and hematuria (33.3%). Mild and moderate activity (60%) and vitamin D insufficiency (62.2%) were related. No significant statistical association was found between high activity levels and vitamin D levels. Conclusions: Serum levels of vitamin D were evaluated; it turned out that white women with the disease presented low levels of vitamin D and disease activity, although no significant association was demonstrated.
