Objective:To report the experience in three Brazilian institutions with the use of rituximab in patients with different clinical forms of lupus erythematosus systemic in activity.Methods:The study consisted of a sample of 17 patients with LES, who were already being treated, but that at some stage of the disease showed refractory symptoms. The patients were subdivided into groups according to the clinical manifestation, and the responses for the use of rituximab were rated as complete, partial or no response. Data were collected through a spreadsheet, and used specific parameters for each group. The treatment was carried on by using therapeutic dose of 1g, and repeating the infusion within an interval of 15 days.Results:The clinical responses to rituximab of the group only hematological and of the group only osteoarticular were complete in all cases. In the renal group there was a clinical complete response, two partial and one absent. In the renal and hematological group complete response, there was one death and a missing response. The pulmonary group presented a complete response and two partial.Conclusion:The present study demonstrated that rituximab can bring benefits to patients with lupus erythematosus systemic, with good tolerability and mild side effects; it presented, however, variable response according to the system affected.
Background
Amyotrophic Lateral Sclerosis (ALS) is a rare, progressive, and fatal neurodegenerative disease due to upper and lower motor neuron involvement with symptoms classically occurring in adulthood with an increasing recognition of juvenile presentations and childhood neurodegenerative disorders caused by genetic variants in genes related to Amyotrophic Lateral Sclerosis. The main objective of this study is detail clinical, radiological, neurophysiological, and genetic findings of a Brazilian cohort of patients with a recent described condition known as Spastic Tetraplegia and Axial Hypotonia (STAHP) due to SOD1 deficiency and compare with other cases described in the literature and discuss whether the clinical picture related to SOD1 protein deficiency is a new entity or may be represent a very early-onset form of Amyotrophic Lateral Sclerosis.
Methods
We conducted a case series report which included retrospective data from five Brazilian patients with SOD1 protein deficiency of a Brazilian reference center for Neuromuscular Disorders. Clinical data were obtained from a review of the medical records and descriptive statistics and variables were summarized using counts and percentages of the total population.
Results
All 5 patients presented with a childhood-onset neurodegenerative disorders characterized by spastic tetraplegia with axial hypotonia in all cases, with gestational history showing polyhydramnios in 4/5 and intrauterine growth restriction in 3/5 patients, with most patients initially presenting a normal motor development until the six month of life or during the first year followed by a rapidly progressive motor decline with severe dysphagia and respiratory insufficiency in all patients accompanied by cognitive impairment in 3/5 patients. All patients were homozygous for the c.335dupG (p.Cys112Trpfs*11) mutation in the SOD1 gene with completely decreased enzyme activity.
Conclusions
This case series is the biggest data collection of the new recent clinical entity described as Spastic Tetraplegia and Axial Hypotonia (STAHP) due to SOD1 deficiency.
The Brazilian Portuguese version of SySQ proved to be reproducible and valid for our population, using a recognized methodology for translation and cultural adaptation of questionnaires, as well as to assess the reproducibility and validity.
This article is a systematic review of the literature about the coexistence of cancer and autoimmune rheumatic diseases, their main associations, cancers and possible risk factors associated, with emphasis on existing population-based studies, besides checking the relation of this occur with the use of the drugs used in the treatment of autoimmune diseases. A search was conducted of scientific articles indexed in the Cochrane / BVS, Pubmed / Medline and Scielo / Lilacs in the period from 2002 to 2012. Also consulted was the IB-ICT (Brazilian digital library of theses and Masters), with descriptors in Portuguese and English for "Systemic sclerosis", "Rheumatoid Arthritis", " Systemic Lupus Erythematosus" and "Sjögren's syndrome", correlating each one with the descriptor AND "neoplasms". The results showed that in the database IBICT a thesis and a dissertation for the descriptor SLE met the inclusion criteria, none met RA one thesis to SS. Lilacs in the database/Scielo found two articles on "Rheumatoid Arthritis" AND "neoplasms". In Pubmed/Medline the inicial search resulted in 118 articles, and 41 were selected. The review noted the relationship between cancer and autoimmune rheumatic diseases, as well as a risk factor for protection, although the pathophysiological mechanisms are not known.
Objective: The description of a new genetic association with late-onset axonal Charcot-Marie-Tooth disease (CMT). Method. A 57-year-old Brazilian woman presented with a slowly progressive history of paresthesia, muscle wasting and weakness in her lower limbs since age 50 years. Examination disclosed peroneal amyotrophy, bilateral pes cavus, mild distal weakness, reduced vibration, pain and temperature sensation in the the lower limbs and brisk tendon reflexes. Results. Neurophysiological studies showed chronic sensorimotor axonal polyneuropathy. Whole-genome sequencing showed compound heterozygous pathogenic variants in the TECPR2 gene (14q32.31). Conclusion. This novel genetic presentation of late-onset axonal CMT with brisk tendon reflexes associated with TECPR2.
A 39-year-old man presented with progressive gait disturbance and urinary incontinence. Medical history disclosed nephrolithiasis, dark urine, osteopenia and osteoarthrosis for 15 years. Examination disclosed crural spastic paraparesis with sensory level at T1 and hyperpigmentation of the sclerae (figure). Neuroimaging studies disclosed cervical spondylotic myelopathy and several discs prolapses. Homogentisic acid levels by HPLC were high in 24hour urine.Alkaptonuria or inherited ochronosis is an autosomal recessive inherited metabolic disorder involving mainly the joints, cardiovascular and genitourinary systems. Dark urine and sclerae and diffuse osteoarthropathy represent clues for clinical suspicion. 1,2 Early adult-onset cervical spondylotic myelopathy represents a severe neurologic complication. 1,2
