RESUMEN

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.

RESUMEN

Summary@#Treatment of refractory cutaneous lupus is challenging. When conventional therapy, including hydroxychloroquine (HCQ), corticosteroids and immunosuppressants, has failed, the addition of quinacrine may be a promising option. We describe a case of refractory chronic cutaneous lupus erythematosus (CCLE) who responded well to quinacrine.

RESUMEN

Introduction@#Lupus panniculitis (LP) is an unusual type of cutaneous lupus erythematosus (CLE) wherein the cutaneous inflam- matory reaction involves primarily the deeper dermis and subcutaneous fat. It is characterized by the appearance of recurrent, mostly asymptomatic, firm, nodules or plaques, involving the face, upper limbs, and buttocks.@*Case report@#In our case, a 30-year-old female presented with a non-tender, non-movable nodule on the left breast, 6 weeks prior to her admission. She had fever, chills, and joint pains. The patient later developed hyperpigmented plaques on the infra- clavicular area, and left flank extending to the abdomen. Urinalysis showed proteinuria, and RBC cast. She also had leukopenia, and anemia on CBC. Chest computerized tomography (CT) scan revealed a heterogeneously enhancing soft tissue mass in the base of the neck at the right infraclavicular region with malignant features. ANA titer was normal, while skin biopsy on two sites and direct immunofluorescence studies were compatible with lupus panniculitis. She was managed as a case of systemic lupus erythematosus (SLE) using a combination of hydroxychloroquine, and oral corticosteroids, which afforded temporary relief of symptoms. The patient however was lost to follow-up and opted for alternative medicine, and subsequently succumbed to the complications of SLE.@*Conclusion@#This case highlights the importance of a carefully made assessment after an accurate clinicopathological cor- relation was done. This case also emphasizes that although LP if associated with SLE may signify a milder condition, judicious monitoring and follow-up must still be undertaken since management is based on the disease activity.

RESUMEN

Introduction: Systemic lupus erythematosus is an autoimmune disease that affects multiple organs. It is well known that lupus patients have higher risk of osteoporosis, but if the disease affects mandibular cortical bone and alveolar bone is not fully established. Objective: The objective of this study was to evaluate periodontal disease defects and mandibular osteoporotic alterations in patients with lupus as compared to healthy patients using panoramic radiographs. Material and Methods: The panoramic radiographs of 72 patients with lupus and 360 healthy patients were evaluated for the presence of bone loss secondary to periodontal disease, classified as horizontal and vertical bone loss. We also assessed mandibular osteoporotic alterations by using the mandibular cortical index. Logistic regression analysis was applied to estimate the risk of mandibular osteoporotic alterations as well as horizontal and vertical bone loss in patients with lupus as compared to healthy patients. Results: There were no statistically significant differences between groups in the presence of horizontal bone defects and mandibular cortical indexes. However, patients with lupus demonstrated that patients with lupus were 2.17 more likely to present vertical bone loss than healthy patients. Conclusions: Patients with lupus might have higher risk of vertical bone loss than healthy patients due to pathophysiology of their disease. Further larger prospective studies should be performed to confirm our findings (AU)


Introdução: Os lúpus eritematoso sistêmico é uma doença autoimune que afeta múltiplos órgãos. Pacientes com lúpus têm maior risco de osteoporose, mas é necessário elucidar-se como a doença afeta o esqueleto maxilo-mandibular. Objetivo: O objetivo deste estudo foi avaliar defeitos ósseos por doença periodontal e alterações osteoporóticas mandibulares em pacientes com lúpus, em comparação com pacientes saudáveis, utilizando-se radiografias panorâmicas. Material e Métodos: As radiografias panorâmicas de 72 pacientes com lúpus e 360 pacientes saudáveis foram avaliadas quanto à presença de defeitos ósseos verticais e horizontais por doença periodontal. Foram também avaliadas as alterações osteoporóticas da mandíbula por meio do índice da cortical mandibular. A regressão logística foi aplicada para estimar o risco de alterações osteoporóticas mandibulares, bem como a perda óssea horizontal e vertical em pacientes com lúpus, em comparação com pacientes saudáveis. Resultados: Não houveram diferenças estatisticamente significantes entre os grupos no tocante à presença de defeitos ósseos horizontais quanto à redução da densidade mineral óssea aferida por meio do índice da cortical mandibular. No entanto, pacientes com lúpus apresentaram 2,17 mais risco à perda óssea vertical do que pacientes saudáveis. Conclusões: Pacientes com lúpus podem ter maior risco de apresentar defeito ósseo vertical do que pacientes saudáveis devido à fisiopatologia de sua doença. Novos estudos prospectivos devem ser realizados para confirmar estes achados (AU)

RESUMEN

Abstract Lupus erythematosus tumidus is a rare dermatosis. It is considered a subtype of chronic cutaneous lupus erythematosus of uncertain pathogenesis, favorable prognosis and rare association with systemic lupus erythematosus. Clinically, it manifests as urticarial-like plaques in photo exposed areas, mainly affecting adults, being extremely rare in pediatric age. Herein, we present two cases of six and nine-year-old male patients with clinical and histological characteristics typical of lupus erythematosus tumidus and poor response to first-line treatment (topical, intralesional steroids and topical calcineurin inhibitors); therefore, it was decided to start systemic therapy with antimalarials, obtaining a very good response.


Resumen El lupus eritematoso tumidus es una dermatosis poco frecuente. Es considerada una variante del lupus eritematoso cutáneo crónico, de patogénesis incierta, pronóstico favorable y rara asociación con lupus eritematoso sistémico. Clínicamente, se manifiesta como placas de aspecto urticarial en zonas fotoexpuestas, que principalmente afectan a los adultos, siendo extremadamente rara en edad pediátrica. A continuación presentamos dos casos de pacientes de sexo masculino de seis y nueve años, con características clínicas e histológicas típicas de lupus eritematoso tumidus y poca respuesta al tratamiento de primera línea (esteroides tópicos, intralesionales e inhibidores de calcineurina tópica), por lo que se decidió iniciar manejo sistémico con antimalárico, obteniendo muy buena respuesta terapéutica.

RESUMEN

Neonatal lupus erythematosus (NLE) is a rare autoimmune disease that has a clinical spectrum of cutaneous, cardiac, and systemic abnormalities in neonates. It is caused by transplacental passage of maternal anti-Ro and/or anti-La autoantibodies, which result in skin lesions such as subacute cutaneous lupus erythematosus, congenital heart block, and liver function and hematologic abnormalities. We report a case of NLE in a 31-day-old female infant who was born to a clinically asymptomatic mother with anti-SSA/Ro and anti-SSB/La antibodies. The baby presented with multiple erythematous patches and annular plaques on the face and trunk. The skin biopsy showed slight follicular plugging, focal hydropic degeneration of the basal epidermis and mild edema, telangiectasia, and perivascular and interstitial lymphohistiocytic infiltration in the upper dermis. Her serological tests were positive for antinuclear antibody (ANA), anti-SSA/Ro, and anti-SSB/La. These findings are consistent with NLE. The mother also had a positive autoantibody profile for ANA, anti-SSA/Ro, and anti-SSB/La without clinical symptoms.

RESUMEN

Cutaneous lupus erythematosus is a previously undiagnosed side‑effect of ranibizumab. Here, we present a case of an 82‑year‑old female Caucasian patient with wet age‑related macular degeneration. Following a single intraocular injection of Lucentis (ranibizumab), she developed a subacute cutaneous lupus erythematosus which, with treatment, took nearly 12 months to resolve. This shows that cutaneous lupus erythematosus is a potential side‑effect of many medications, including ranibizumab, as in our case and, in an aging population where polypharmacy is a growing reality, clinicians should be aware of how to diagnose and best manage such cases.

RESUMEN

INTRODUÇÃO: Recentemente, relatou-se uma associação entre artrite reumatoide (AR) e a variante rs7700944 G>A nos domínios imunoglobulina e mucina de células T (TIM-4). OBJETIVO: Investigar o impacto desse polimorfismo na suscetibilidade a AR em uma amostra da população iraniana. PACIENTES E MÉTODOS: Este estudo caso-controle foi conduzido em 120 pacientes com AR e 120 indivíduos saudáveis. O polimorfismo rs7700944 do gene TIM-4 foi determinado usando-se o ensaio tetra amplification refractory mutation system-polymerase chain reaction (T-ARMS-PCR). RESULTADOS: Não se observou diferença significativa quanto ao polimorfismo rs7700944 do gene TIM-4 entre os pacientes com AR e os indivíduos saudáveis. Nas mulheres, não houve associação significativa quanto ao polimorfismo rs7700944 do gene TIM-4 nos dois grupos. Nos homens, o genótipo GA+AA, em comparação ao GG, aumentou o risco para AR (OR = 5,15; IC 95% = 1,30-20,48; P = 0,020). Além disso, os resultados mostraram que o alelo rs7700944 A aumentou o risco para AR (OR = 4,39; IC 95% = 1,43-13,54; P = 0,009). CONCLUSÃO: Nossos resultados não confirmam a existência de associação entre AR e o polimorfismo rs7700944 do gene TIM-4. Uma interação entre esse polimorfismo e sexo sugere uma associação sexo-específica entre AR e esse polimorfismo de nucleotídeo único, que ainda requer elucidação.


INTRODUCTION: Recently, an association between rheumatoid arthritis (RA) and the rs7700944 G>A variant in the T-cell immunoglobulin and mucin domains 4 (TIM-4) has been reported. OBJECTIVE: The present study aimed at investigating the impact of that polymorphism on susceptibility to RA in a sample of the Iranian population. Patients and methods: This case-control study was conducted on 120 patients with RA and 120 healthy subjects. The rs7700944 polymorphism in the TIM-4 gene was determined using tetra amplification refractory mutation system-polymerase chain reaction (T-ARMS-PCR) assay. RESULTS: No significant difference was observed regarding the rs7700944 polymorphism of the TIM-4 gene between patients with RA and normal individuals. In females, no significant association was found between the groups concerning the rs7700944 polymorphism of the TIM-4 gene. In males, the GA+AA genotype increased the risk of RA in comparison with the GG genotype (OR = 5.15, 95% CI = 1.30-20.48, P = 0.020). Furthermore the results showed that the rs7700944 A allele increased the risk of RA (OR = 4.39, 95% CI = 1.43-13.54, P = 0.009). CONCLUSION: Our results do not support an association between the rs7700944 polymorphism of the TIM-4 gene and RA. An interaction between this polymorphism and sex suggests a sex-specific association between this single nucleotide polymorphism and RA, which remains to be fully elucidated.

RESUMEN

A vasculite mesentérica lúpica (VML) é uma rara causa de dor abdominal aguda. Há poucos relatos de caso demonstrando VML em adultos e, particularmente, em crianças e adolescentes. No entanto, para o nosso conhecimento, a prevalência dessa grave vasculite em uma população pediátrica com lúpus ainda não foi estudada. Portanto, dados de 28 anos consecutivos foram revisados e incluídos 5.508 pacientes em seguimento no Hospital da Faculdade de Medicina da Univesidade de São Paulo (FMUSP). Identificamos 279 (5,1%) casos que preencheram critérios de classificação diagnóstica do American College of Rheumatology para lúpus eritematoso sistêmico (LES) e um (0,4%) desses apresentou VML. Este paciente recebeu diagnóstico de LES aos 11 anos de idade. Aos 13 anos foi hospitalizado com dor abdominal difusa e aguda, náuseas, vômitos biliosos, distensão e rigidez abdominal, com descompressão brusca positiva. O paciente foi prontamente submetido à laparotomia exploradora, identificando isquemia intestinal segmentar, com edema de parede intestinal e aderências. Foi realizada ressecção parcial de intestino delgado, com lise das aderências e pulsoterapia com metilprednisolona. A análise histopatológica identificou arterite de vasos mesentéricos. Após 13 dias, apresentou recorrência de dor abdominal difusa intensa, sendo novamente submetido à laparotomia exploradora, identificando obstrução em intestino delgado por aderências, com gangrena intestinal. Nova ressecção intestinal foi realizada, além de pulsoterapia com metilprednisolona e infusão de imunoglobulina. Portanto, VML é uma rara e grave manifestação abdominal na população com lúpus pediátrico, e pode ser a única manifestação de atividade da doença. Além disso, este estudo reforça a importância do diagnóstico precoce e do tratamento imediato.


Lupus mesenteric vasculitis (LMV) is a rare cause of acute abdominal pain. Few cases of LMV have been reported in adults, children and adolescents. However, to our knowledge, the prevalence of that severe vasculitis in a pediatric population with lupus is yet to be studied. This study reviewed data from 28 consecutive years and included 5,508 patients being followed up at the hospital of the Faculdade de Medicina of the Univesidade de São Paulo (FMUSP). We identifi ed 279 (5.1%) patients meeting the American College of Rheumatology classifi cation criteria for the diagnosis of systemic lupus erythematosus (SLE), one of whom (0.4%) had LMV. That male patient was diagnosed with SLE at the age of 11 years. At the age of 13 years, he was hospitalized with diffuse and acute abdominal pain, nausea, bilious vomiting, abdominal distension, rebound tenderness, and abdominal muscle guarding. The patient underwent laparotomy immediately, and segmentary intestinal ischemia with intestinal wall edema and adhesions were identifi ed. Partial small bowel resection with lysis of the adhesions was performed, as were pulses of intravenous methylprednisolone. The histopathologic analysis evidenced mesenteric arteritis. After 13 days, the diffuse and intense abdominal pain recurred, and the patient underwent a new laparotomy, during which adhesive small bowel obstruction with intestinal gangrene was identifi ed. New intestinal resection was performed, and the patient received pulses of intravenous methylprednisolone and infusion of immunoglobulin. Thus, LMV is a rare and severe abdominal manifestation of the pediatric population with lupus, and can be the only manifestation of disease activity. In addition, this study stresses the importance of the early diagnosis and immediate treatment.

RESUMEN

Kikuchi's disease (KD), histiocytic necrotizing lymphadenitis, is a rare self-limited lymphadenopathy, which usually affects young women. KD has been reported to precede, coexist with or follow the diagnosis of other entities, such as systemic lupus erythematosus (SLE), adult-onset Still's disease, Hashimoto's disease, and viral infections. In a few cases, KD is associated with cutaneous lupus erythematosus (CLE), without systemic involvement. Herein, we report the first Korean case of KD associated with lupus erythematous profundus in a 9-year-old boy.

RESUMEN

O lúpus eritematoso cutâneo crônico, caracterizado, sobretudo, pelo lúpus discoide, é uma entidade clínica incomum, porém de elevada prevalência em mulheres em idade fértil. A sua etiologia é desconhecida, mas fatores genéticos, autoimunes, hormonais e ambientais compõem o processo fisiopatológico da doença. Os meios diagnósticos utilizados para que se possa iniciar o tratamento específico, composto de protetores solares, corticosteroides tópicos e, se preciso, medicações sistêmicas, principalmente os antimaláricos, são o exame clínico, a imunofluorescência direta e o estudo histopatológico. Este artigo descreve de maneira sucinta os principais aspectos epidemiológicos, clínicos, diagnósticos e terapêuticos do lúpus eritematoso cutâneo crônico, conforme revisão de literatura.

RESUMEN

Subacute cutaneous lupus erythematosus (SCLE) includes the papulosquamous and annular-polycyclic variants that present with psoriasiform lesions and annular/polycyclic erythema, respectively. Most patients predominantly have either one or the other subtype, but it is rare that patients have a combination of both lesions. A 13-year-old boy had both erythematous, well-defined, annular-shaped patches and erythematous, ill-defined, hyperkeratotic scaly patches that were scattered on the entire body. Although his clinical manifestations seemed typical for SCLE, his laboratory findings were all negative for LE-specific autoantibodies, including ANA, anti-Ro/SS-A antibody, anti-La/SS-B antibody, anti-dsDNA antibody, etc. The characteristic histopathological features for lupus erythematosus and the granular deposition of IgG and C3 along the dermo-epidermal junction, as detected by direct immunofluorescence testing of lesional skin biopsy specimens, could lead us to the diagnosis of SCLE. We herein report on a case of SCLE that simultaneously presented with both papulosquamous and annular-shaped lesions.

RESUMEN

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare disease. The prognosis is poor in most cases with rapid progression despite administering chemotherapy. A 67-year-old man complained of skin rashes on his back and this spread to the trunk, face, arms and thighs, and he was initially diagnosed with cutaneous lupus erythematosus according to the skin biopsy. The skin rashes then became aggravated on a trial of low dose methylprednisolone for 3 months. Repeated skin biopsy revealed a diffuse infiltration of lymphoid cells with medium sized nuclei, positive for CD4 and CD56, negative for Epstein-Barr virus (EBV), indicating a diagnosis of BPDCN. Further workups confirmed stage IVA BPDCN involving the skin, multiple lymph nodes, the peripheral blood and the bone marrow. He was treated with six cycles of combination chemotherapy consisting of ifosphamide, methotrexate, etoposide, prednisolone and L-asparaginase, and he achieved a partial response. Herein we report on a rare case of BPDCN that was initially misinterpreted as cutaneous lupus erythematosus.

RESUMEN

Drug-induced subacute cutaneous lupus erythematosus (SCLE) is associated with use of the following classes of medications: anti-hypertensives, anti-cholesterolemia, anti-psychotics, and anti-inflammatory drugs. Docetaxel is an anti-neoplastic agent, which is widely used for treatment of non-small cell lung cancer. Few cases of docetaxel-induced SCLE have been reported in the medical literature. Here, we report the case of a 58-year-old female patient who developed drug-induced SCLE after administration of docetaxel. After 4 cycles of chemotherapy with docetaxel and cisplatin, erythematous skin eruptions developed on the patient's face. Skin biopsies of the eruptions were remarkable for interfacing dermatitis with basement membrane thickening. Immunofluorescent study revealed characteristic features of SCLE, including granular deposition of IgM, C3, and apoptotic bodies along the basement membrane. The skin eruptions resolved gradually after cessation of drug and with the use of topical corticosteroids.

RESUMEN

BACKGROUND: Chronic cutaneous lupus erythematosus (CCLE) is a well-known autoimmune cutaneous disease that is part of the lupus erythematosus (LE) spectrum. OBJECTIVE: The aim of this study is to elucidate the clinical and laboratory features and the possible factors that are relevant to the aggravation of CCLE, as well as the possible precipitating factors for the transformation of cutaneous LE into multi-organ systemic disease. METHODS: A total of forty Korean patients with CCLE were selected for the study. We performed clinical examinations for the lesion-morphology and topographic distribution, as well as tests for the LE-related laboratory abnormalities, the precipitating factors for aggravation and the factors relevant to systemic lupus erythematosus (SLE). RESULTS: Among these forty CCLE patients, thirty-two patients (80.0%) had discoid erythema (DLE) lesions and 39 patients (97.5%) had cutaneous CCLE lesions that appeared on the head and neck areas. Twenty-nine patients (72.5%) had more than 3 CCLE lesions. All of the laboratory and clinical features of SLE were observed more frequently in the patients with widespread DLE with multiple lesions than in those patients with localized DLE. The most frequent aggravating factors that were recognized among these forty patients with CCLE were UV light, cold-exposure, physical trauma, pregnancy and smoking. Transformation into SLE developed in three patients (7.5%) during a 4-year period, and the most relevant findings related to the transformation into SLE were positive findings for leukopenia, antinuclear antibodies, anti-DNA antibodies and an increase of the erythrocyte sedimentation rate. CONCLUSION: Among these forty Korean cases of CCLE, multiple lesions of DLE on the head and neck areas were the most frequent clinical form, and this pattern is similar to the pattern seen in Caucasian people. The most frequent aggravating factor observed in individual patients was UV light. Patients with a widespread form of CCLE may have some laboratory findings of SLE such as leukopenia, antinuclear antibodies, anti-DNA antibodies or an elevated erythrocyte sedimentation rate. These patients should be observed closely because their disease might be transformed to SLE.

RESUMEN

BACKGROUND: Scarring alopecias are classified into primary and secondary types according to the initial site of inflammation. In primary scarring alopecias, the hair follicle is the main target of destruction; the term secondary cicatricial alopecia implies that follicular destruction is not the primary pathologic event. AIMS: To review the histopathologic diagnoses of cases of cicatricial alopecia in order to classify them according to the North American Hair Research Society. PATIENTS AND METHODS: Patients with biopsy specimens diagnosed as cicatricial alopecia seen from 2000 to 2005 at the Dermatologic Department of Hospital das Clinicas, São Paulo University Medical School had hematoxylin and eosin, Periodic acid-Schiff and Weigert stained slides reevaluated and sub-typed into different primary cicatricial alopecias. RESULTS: Thirty-eight cases of primary cicatricial alopecias were reclassified as: chronic cutaneous lupus (17), lichen planus pilaris (4), pseudopelade of Brocq (12), folliculitis decalvans (3), dissecting folliculitis (1), and non-specific scarring alopecia (1). In our cases, the methods employed allowed an accurate diagnosis in 12 of 13 cases (92.3 percent) previously classified as non-specific cicatricial alopecias. CONCLUSIONS: Even in the late, pauci or non-inflammatory phases, an approach with systematic evaluation of a constellation of criteria in routine hematoxylin and eosin stain, Periodic acid-Schiff and Weigert stain allowed for a more accurate diagnosis of cicatricial alopecias.
