A.; SILVA, Clovis A.; AIKAWA, Nadia E.; JESUS, Adriana A.; MORAES, Julio C. B.; MIRAGLIA, Joao; ISHIDA, Maria A.; BUENO, Cleonice; PEREIRA, Rosa M. R.; BONFA, EloisaObjectiveRecent findings demonstrated a reduced immunogenicity of the influenza A H1N1/2009 vaccine in juvenile rheumatic diseases. However, a point of concern is whether the vaccine could induce disease flares. The aim of this study was to assess the disease safety of and the possible influence of disease parameters and therapy on nonadjuvant influenza A H1N1 vaccine response of juvenile systemic lupus erythematosus (SLE) patients. MethodsOne hundred eighteen juvenile SLE patients and 102 healthy controls of a comparable age were vaccinated. Seroprotection rate, seroconversion rate, and factor increase in geometric mean titer (GMT) were calculated and effective immune response was defined by the Food and Drug Administration and the European Committee for Proprietary Medicinal Products vaccine immunologic standards. Disease parameters, treatment, and adverse events were evaluated. ResultsAge was comparable in juvenile SLE patients and controls (mean +/- SD 16.0 +/- 3.5 versus 15.9 +/- 4.5 years; P = 0.26). Three weeks after immunization, seroprotection rate (73.7% versus 95.1%; P < 0.001), seroconversion rate (63.6% versus 91.2%; P < 0.001), GMT (90.8 versus 273.3; P < 0.001), and factor increase in GMT (8.1 versus 19.9; P < 0.001) were significantly lower in juvenile SLE patients versus controls. Nonseroconversion was associated with a higher frequency of patients with a Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score 8 (48.8% versus 24%; P = 0.008) and a higher mean +/- SD current glucocorticoid dosage (18 +/- 21.4 versus 10.5 +/- 12.5 mg/day; P = 0.018). Multivariate logistic regression including a SLEDAI-2K score 8 revealed that only the SLEDAI-2K remained a significant factor for nonseroconversion (odds ratio 0.42, 95% confidence interval 0.18-0.98; P = 0.045). Disease parameters remained stable throughout the study and no severe vaccine adverse events were observed. ConclusionThe present study demonstrated adequate disease safety and is the first to discriminate that high disease activity impairs influenza A H1N1/2009 vaccine antibody production in juvenile SLE, in spite of an overall immune response within recommended levels.
- Mesenteric vasculitis in a juvenile systemic lupus erythematosus patient(2013) ALBUQUERQUE-NETTO, Adao F.; CAVALCANTE, Erica G.; SALLUM, Adriana M. E.; AIKAWA, Nadia E.; TANNURI, Uenis; SILVA, Clovis Artur Almeida daLupus 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 Sao Paulo (FMUSP). We identified 279 (5.1%) patients meeting the American College of Rheumatology classification 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 identified. 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 identified. 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.
- Effective seroconversion and safety following the pandemic influenza vaccination (anti-H1N1) in patients with juvenile idiopathic arthritis(2013) AIKAWA, N. E.; CAMPOS, L. M. A.; GOLDENSTEIN-SCHAINBERG, C.; SAAD, C. G. S.; RIBEIRO, A. C.; BUENO, C.; PRECIOSO, A. R.; TIMENETSKY, MdoC; SILVA, C. A. A.; BONFA, E.Objectives: To assess the vaccine response in juvenile idiopathic arthritis (JIA) as an extension of previous observation of immunogenicity and safety of a non-adjuvanted influenza A H1N1/2009 vaccine in a large population of juvenile rheumatic diseases. Moreover, to assess the possible influence of demographic data, disease subtypes, disease activity, and treatment on immunogenicity and the potential deleterious effect of the vaccine in the disease itself, particularly in the number of arthritis and inflammatory markers. Methods: A total of 95 patients with JIA and 91 healthy controls were evaluated before and 21 days after vaccination, and serology for anti-H1N1 was performed by haemagglutination inhibition assay (HIA). Patient and physician visual analogue scales (VAS), Childhood Health Assessment Questionnaire (CHAQ), number of active joints, acute phase reactants, and treatments were evaluated before and after vaccination. Adverse events were also reported. Results: JIA patients and controls were comparable regarding mean current age (14.9 +/- 3.2 vs. 14.6 +/- 3.7 years, p = 0.182). After vaccination, the seroconversion rate was significantly lower in JIA patients compared to controls (83.2% vs. 95.6%, p = 0.008), particularly in the polyarticular subtype (80% vs. 95.6%, p = 0.0098). Of note, JIA subtypes, number of active joints, acute phase reactants, CHAQ, patient and physician VAS, and use of disease-modifying anti-rheumatic drugs (DMARDs)/immunosuppressive drugs were similar between seroconverted and non-seroconverted patients (p > 0.05). Regarding vaccine safety, no deterioration was observed in the number of active joints and acute phase reactants during the study period. Conclusion: Influenza A H1N1/2009 vaccination in JIA induces a lower but effective protective antibody response probably independent of disease parameters and treatment with an adequate disease safety profile.
- Pulmonary cryptococcosis in childhood systemic lupus erythematosus and Sjogren syndrome overlap: a rare opportunistic infection(2013) MARQUES, V. L. S.; GOMES, R. C.; VIOLA, G. R.; MAIA, M. M.; DURIGON, G. S.; AIKAWA, N. E.; SILVA, C. ArturMeningitis is the main manifestation of cryptococcosis in adult systemic lupus erythematosus (SLE) patients, and other organs and systems, such as the lungs, are rarely affected in this fungal infection. To our knowledge, no case of pulmonary cryptococcosis has been described in the pediatric lupus population. Therefore, we report herein one patient with childhood SLE (C-SLE) and Sjogren's syndrome overlap that presented encapsulated Cryptococcus yeast cells in lung tissue. A 14-year-old girl was diagnosed with C-SLE. At the age of 16 years and 5 months, she presented with fever, cough and dyspnea, without headache, vomiting, and also without signs of meningeal irritation or other clinical manifestations. She was being treated with mycophenolate mofetil, hydroxychloroquine and prednisone. Chest radiography and chest computer tomography showed a single nodule in the left posterior apex and three nodular lesions in the left hemithorax respectively. Bronchoalveolar lavage and transbronchial biopsy were normal and without isolation of bacteria or fungi. Voriconazole was empirically introduced for 21 days. Fifteen days after the first biopsy, she underwent open thoracotomy with surgical left lung biopsy and was diagnosed with pulmonary cryptococcosis. Voriconazole was replaced with oral fluconazole and this antifungal therapy was maintained with improvement of clinical manifestations and without marked alteration of radiological images. In conclusion, we report the first case of pulmonary cryptococcosis in Sjogren's and C-SLE patient with a satisfactory clinical response to antifungal therapy. Fungal infections should be excluded in the presence of lung nodules and etiological identification is required for proper treatment.

E.; TRUDES, G.; CAMPOS, L. M. A.; PEREIRA, R. M. R.; MORAES, J. C. B.; RIBEIRO, A. C.; MIRAGLIA, J.; TIMENETSKY, M. do Carmo S.; BONFA, E.; SILVA, C. A.Objectives The aim of this study was to evaluate the immunogenicity and safety of the influenza A H1N1/2009 vaccine in children under 9 years old with autoimmune rheumatic diseases (ARD). Methods Thirty-eight ARD patients and 11 healthy children received two doses of non-adjuvanted influenza A/California/7/2009 (H1N1) virus-like vaccine. Subjects were evaluated before and 21 days after vaccination. Seroprotection (SP) and seroconversion (SC) rates, geometric mean titers (GMT) and factor increases (FI) in GMT were calculated. Results Mean ages were comparable between patients and controls. Pre-vaccination SP and GMT were similar in patients and controls (p>0.05). Three weeks after immunization, SP (81.6% vs. 81.8%, p=1.0), SC (81.6% vs. 90.9%, p=0.66), GMT (151.5 vs. 282.1, p=0.26) and the FI in GMT (16.7 vs. 36.3, p=0.23) were similar in patients and controls, with both groups achieving an adequate response, according to the European Medicines Agency and Food and Drug Administration standards. Analysis of the possible factors influencing SC showed no difference in demographic data, leukocyte/lymphocyte counts or immunosuppressant use between seroconverted and non-seroconverted patients (p>0.05). The vaccine demonstrated a satisfactory safety profile in this population. Conclusions Two doses of influenza A H1N1/2009 vaccination induced an effective antibody response and caused adverse events in rare instances, suggesting this vaccine is appropriate and can be recommended for this age group.
