Lupus low disease activity (SLE) in patients treated with belimumab: a single-center real-life experience (2016-2019).

INTRODUCTION: We have been conducting an evaluation of innovative therapies in patients with SLE during the past 15 years. We combine the results observed on extension studies from four different trials in patients receiving either intravenous or subcutaneous belimumab, and evaluated, in Caucasian and Black Brazilian patients. METHODS: Seventy-four patients were part of the study. The Lupus Low Disease Activity State (LLDAS) shown to be an available tool to detect a response in trials was used in this study and statistical comparisons between the different result groups were determined. The period of evaluation was from 12 to 48 months. RESULTS: Seventy-four patients completed the initial study. Four refused to continue the extension evaluation. Seven belonged to the black group (10%); sixty-three were Caucasian (90%). One patient was discontinued due to pregnancy. Nine received a subcutaneous presentation (12.8%). In the subgroup analysis, one patient in the black group had flare (14.2%); five in the intravenous administration had severe flares (8.1%) and were discontinued. Ten had flares adjusted with steroids (eight articular or skin reactivation) and two with renal disease. Of the five severe flares, two required hospitalization. The mean time duration to achieve LLDAS was 6 months. Twenty-seven achieved a steroid-free status and the remaining two patients on 2.5 mg and seventeen were stable on daily 5.0  mg of prednisone. CONCLUSIONS: Using the LLDAS, it was possible to show that the majority of patients receiving belimumab for prolonged periods go into remission steroid-free or in low disease activity in association with the corresponding immunosuppressive treatment. Key Points • Prolonged real-life evaluation confirms the efficacy and steroid-sparing of Belimumab in SLE patients with active disease.

Bone health in cerebral palsy and introduction of a novel therapy.

OBJECTIVE: To assess the bone health status of children with cerebral palsy and the therapeutic effect of denosumab in a subgroup of children with cerebral palsy and decreased bone mass. METHODS: Children with cerebral palsy were evaluated according to their motor disability score (classification system gross motor functions III to V), bone density and bone turnover markers. Dual X-ray energy absorption was used to measure the lumbar spine, and total body, except the head. Thereafter a group of children with cerebral palsy and osteoporosis was treated with denosumab, a fully human monoclonal antibody. Bone turnover markers were measured before and three months after treatment. RESULTS: Reduction in bone mineral density was observed, particularly in children with greater impairment evaluated by the motor score. Decreased bone turnover markers were found in a selected group of children three months after exposure to denosumab. CONCLUSION: Bone loss was present in children with significant impairment of motor function, as well as decreased serum levels of bone resorption markers with new forms.

Comparison of thromboprophylaxis patterns in arthroplasty in public and private hospitals.

OBJECTIVE: To compare therapy for prophylaxis of venous thromboembolism and costs related to hospitalization of patients undergoing total knee and hip replacement within the context of the Brazilian health system. METHODS: A retrospective study of patients undergoing arthroplasty in 2010 in a public hospital and two private hospitals in the state of São Paulo, conducted by means of medical record review. Costs were estimated based on the use of health care resources during hospitalization. A descriptive analysis was performed using frequency and mean (standard deviation) according to the type of care delivered (by public or private organization). RESULTS: A total of 215 patients were evaluated, and 56.3% were submitted to knee surgery and 43.7%, to hip replacement. Approximately 88% and 98% of patients from public and private health services, respectively, received some form of venous thromboembolism prophylaxis, and enoxaparin was the drug most widely used in both systems. The total cost of prophylaxis was R$ 1,873.01 (R$ 26.38 per patient) in the public service and R$ 21,559.73 (R$ 163.33 per patient) in the private service. For the individuals who presented with thromboembolism, the average cost of hospitalization was R$ 6,210.80 and R$ 43,792.59 per patient in public and private health services, respectively. CONCLUSION: Thromboembolism prophylaxis in patients undergoing arthroplasty is most commonly used in the private health services than public organizations, despite its high costs in both services. The cost per patient with thrombosis during hospitalization was higher than the total cost of prophylaxis, suggesting that prevention is associated to better cost-benefit ratio.

When anti-TNF fails, anti-IL12-23 is an alternate option in psoriasis and psoriatic arthritis.

Patients with psoriasis and psoriatic arthritis respond to anti-TNF therapy, but not all patients maintain effective response, and some do not respond. In this article, we demonstrate the role of a new pathogenetic pathway to some extent TNF-independent in these patients. Anti-IL12-23 is a new and alternate mode of therapy for patients with recalcitrant response to anti-TNF.

Retention rates of infliximab and tocilizumab during a 3-year period in a Brazilian hospital.

OBJECTIVE: To compare the efficacy and the period of use of tocilizumab and infliximab during treatment of rheumatoid arthritis patients. METHODS: The period of use of two biologics with different mechanisms of action were compared in treatment of rheumatoid arthritis patients. RES ULTS: Both medications showed efficacy, but the period of use with no loss of efficacy was longer in patients receiving tocilizumab when compared to infliximab. CONCLUSION: Tocilizumab maintains a period of use significantly longer as compared with infliximab in patients with rheumatoid arthritis treated at a single organization.

Decreased need of large joint replacement in patients with rheumatoid arthritis in a specialized Brazilian center.

Disease-modifying antirheumatic biological and non-biological therapies are associated with reduced disease progression and joint destruction. Suggestions have been made that total knee and hip joint arthroplasty indications are decreasing as a beneficial effect of the new forms of therapy for rheumatoid arthritis. We present findings of our institution on the incidence of joint arthroplasty in the past few years in patients with rheumatoid arthritis and the increase in the numbers of procedures not associated with inflammatory arthritis.

Total hip and knee joint replacement: perioperative clinical aspects.

OBJECTIVE: To understand the profile of patients undergoing hip and knee replacement during two years, and to compare the data obtained with the literature. METHODS: A total of 323 medical records were reviewed to analyze the perioperative data of patients submitted to hip and knee replacement. RESULTS: Osteoarthritis was the main indication for both procedures and male patients were heavier than females (p < 0.05). Hypertension was the prevalent disease among patients. Blood loss was more frequent in knee surgery than in the hip. CONCLUSIONS: The profile of patients undergoing total arthroplasty improved substantially over the past decade due to shorter hospital stay, lower risk of thromboembolic events and no infection as compared to previous reports.

AL amyloidosis in a young adult: remission with autologous stem cell transplantation.

Autologous stem cell transplant is one of the therapies employed in the treatment of primary amyloidosis or AL. The authors report on a 46-year-old patient with bilateral periorbital hematomas, macroglossia who presented, during the investigation, IgG-Kappa paraprotein in serum. The diagnosis of primary amyloidosis or AL was confirmed and the treatment proposed consisted of high-dose melphalan as conditioning regimen before autologous stem cell transplant, which determined complete remission of the disease, along with the disappearance of clinical signs and absence of the monoclonal component.

Diagnosis of growing pains in a Brazilian pediatric population: a prospective investigation.

OBJECTIVE: To establish the clinical aspects of growing pains and to determine, through differential diagnosis, how many patients who referred themselves to a specialized clinic were found to have growing pains. METHODS: This study prospectively examined the presence of growing pains in a self-reported population of children and adolescents with signs and symptoms (lower limb pains) of unexplained etiology. RESULTS: A total of 345 children and adolescents were evaluated; 174 (50.4%) were males and 171 (49.6%) were females. Three hundred cases were classified as growing pains (87%). CONCLUSION: A high frequency of growing pains was found in our study population and it shows that in a prospective evaluation of patients with signs and symptoms of unknown etiology we can find a frequency higher than that reported in literature.

Objetivo Comparar a terapia para profilaxia de tromboembolismo venoso e os custos de pacientes submetidos à artroplastia total de joelho e de quadril dentro do sistema de saúde brasileiro.Métodos Estudo retrospectivo com pacientes submetidos à artroplastia no ano de 2010, em um hospital público e dois hospitais privados no Estado de São Paulo, por meio da revisão de prontuários. Os custos foram estimados com base na utilização de recursos em saúde durante a hospitalização. Análise descritiva de frequência e média (desvio padrão), de acordo com o tipo de atendimento em saúde (público ou privado).Resultados Um total de 215 pacientes foram avaliados, sendo 56,3% submetidos à cirurgia de joelho e 43,7% à cirurgia de quadril. Cerca de 88% e 98% dos pacientes provenientes do serviço público e privado de saúde, respectivamente, receberam algum tipo de profilaxia para tromboembolismo, sendo a enoxaparina o medicamento mais utilizado em ambos sistemas. O custo total da profilaxia foi de R$ 1.873,01 (R$ 26,38 por paciente) no serviço público e R$ 21.559,73 (R$ 163,33 por paciente) no serviço privado. Para os indivíduos com tromboembolismo, o custo médio da internação foi de R$ 6.210,80 e R$ 43.792,59 por paciente atendido nos serviços de saúde público e privado, respectivamente.Conclusão A profilaxia em pacientes submetidos à artroplastia é mais utilizada em pacientes do serviço de saúde privado do que público, apesar dos altos custos em ambos os serviços. Os pacientes com tromboembolismo tiveram um custo maior do que aqueles apenas com profilaxia, mostrando que a prevenção está associada a um maior custo-benefício.

Objetivo: Conhecer o perfil dos pacientes submetidos à artroplastia de quadril e joelho em um período de dois anos e comparar os dados com relatos da literatura. Métodos: Foram revisados 323 prontuários para analisar os dados perioperatórios de pacientes submetidos à substituição da articulação do joelho e do quadril. Resultados: A osteoartrite foi a principal indicação para ambos os procedimentos, e os homens mostraram-se mais pesados que as mulheres (p < 0,05). A hipertensão arterial foi a doença prevalente entre os pacientes. A perda sanguínea foi mais frequente na cirurgia do joelho do que na do quadril. Conclusões: O perfil dos pacientes submetidos à artroplastia melhorou substancialmente nos últimos dez anos, associando a diminuição do período de internação com menor risco de eventos tromboembólicos e ausência de infecção, quando comparados com publicações anteriores.

Amiloidose AL em um adulto jovem: remissão clínica e laboratorial com transplante autólogo de células tronco / AL amyloidosis in a young adult: remission with autologous stem cell transplantation

Transplante autólogo de células tronco é uma das formas de tratamento da amiloidose primária ou AL. Os autores relatam um paciente de 46 anos com hematomas periorbitais bilaterais, macroglossia, em quem, na investigação, se constatou a presença de paraproteínas IgG Kappa no soro. O diagnóstico de amiloidose primária ou AL foi confirmado, e o tratamento proposto com condicionamento com doses altas de Melfalan, seguido de transplante autólogo de células tronco, determinou a remissão completa da doença com desaparecimento de sinais clínicos e ausência do componente monoclonal.
