Effects of a Shortage of Imiglucerase on Three Patients with Type I Gaucher Disease

Background: Children with Gaucher disease type I (GD1) are usually treated with enzyme replacement therapy (ERT) at a dose of 30-60U/Kg/2W. Recently, due to an acute shortage supply of imiglucerase, a reduced dose or a reduced infusion frequency was recommended. Objective: To evaluate the effects of a reduced infusion frequency of imiglucerase over 15 months of follow-up. Patients and Methods: Three patients (1M:2F) were treated with ERT since a median age of 7 years (range 5-12). Only one had bone crisis and Erlenmeyer deformations. Median duration of treatment before dose reduction was 3 years (range 1-8). ERT resulted in total regression of symptoms, normalization of hematological parameters and progressive improvement of chitotriosidase in all patients. In August 2009 infusion schedule was changed from a media 45U/Kg every two weeks to every four weeks. Results: All patients remained asymptomatic and with no major change on hematological parameters except for the patient with bone crisis who presented subnormal platelet count. All patients showed an upward trend in chitotriosidase values. Comments: Although a longer follow-up is needed, is probable that even children completely stabilized can probably not be kept on lower doses even though the reduction of frequency of the infusions represent a lower social burden

Early Infantil Krabbe Disease with Unusual Survival

Introduction: Globoid cell leukodystrophy (Krabbe disease) is caused by a deficiency of the lysosomal galactocerebrosidase that results in progressive demyelination. The sole treatment is hematopoietic cell transplantation, which is only effective if performed before the onset of signs. In the absence of treatment, most children with early infantile Krabbe disease die within 2 years. Case Report: Female patient, first child of non-consanguineous parents, apparently normal till the fifth month of age when she presented with irritability, stiffness with clenched fists, developmental delay and feeding difficulties that progressed rapidly to failure to thrive, apathy, psychomotor regression, few spontaneous movements and spastic tetraparesis. Cerebral MRI showed extensive cerebral white matter abnormalities, relatively sparing the U-fibers, with a pattern of radiating stripes. Galactocerebrosidase activity in leukocytes and fibroblasts and molecular studies confirmed the diagnosis of Krabbe disease. After the rapid and regressive initial phase, she showed no further clinical progression of the disorder and although she did not grow she even showed regression of irritability and had a stable evolution and good visual contact until death over the age of 5 years. Comments: Our case shows that patients may have a stabilized form of disease and that a longer survival than described in the literature without transplant is possible in some patients

Local interpretations on malaria and the discourse on the traditional health care providers in southern Mozambique

The narratives on the diagnosis and causes of malaria are diverse and apparently ambiguous, being based beyond the body, on the social relations among peers, their ancestors, and nature. Based on a qualitative study and a four-year stay in Mozambique, this article analyzes the discourses of patients and biomedical practitioners on traditional health care providers, i.e., tinyanga and zion pastors, linking them to local terminology of malaria, in a rural district in southern Mozambique. In the current context of therapeutic pluralism and high mobility, the lack of solidarity and compassion attributed to tinyanga is supported by the monetization and commodification of their medicinal rituals and knowledge, as well as by competition with other providers in attracting patients. The implementation of zion churches, of Christian nature and performing therapeutic practices similar to tinyanga, is presented as a local advantageous solution due to the strong community connection, the comfort and reciprocity among the members, and the therapeutic results at low cost. In terms of health care policies and clinical practice, the invisibility of zion pastors and the subordinate role of healers is managed according to interests, based on vague ideas and prejudices from biomedical providers. The implementation of health policies that address the local diversity, the existing power relations and medical knowledge and practices can strengthen the biomedical care services and harmonize relations between the providers and the population.info:eu-repo/semantics/publishedVersio

Primary Disorders of Neurotransmitter Metabolism: Experience of a Tertiary Center

Neurotransmitter diseases are a group of inherited disorders attributable to a disturbance of neurotransmitter metabolism. Biogenic amines are neurotransmitters with multiple roles including psychomotor function, hormone secretion, cardiovascular, respiratory and gastrointestinal control, sleep mechanisms, body temperature and pain. Given the multiple functions of monoamines, disorders of their metabolism comprise a wide spectrum of manifestations, with motor dysfunction being the most prominent clinical feature. Methods: Case review of 12 patients from 4 families, with primary disorders of biogenic amine metabolism. Results: Aromatic L-amino acid decarboxylase deficiency (4 patients from 2 families), and GTP-cyclohydrolase (8 patients from 2 families) were the two diseases identified. Age at first symptoms varied between 2 months and 6 years. Developmental delay was present in all cases except 2 patients with GTP cyclohydrolase deficiency. The combination of axial hypotonia and limb dystonia was also frequent. Children with aromatic L-amino acid decarboxylase deficiency exhibited temperature instability, oculogyric crisis and disturbances of sleep. The index case of one family with GTP cyclohydrolase deficiency presented with Parkinsonism (bradykinesia, rigidity and hypomimia). Analysis of neurotransmitters and their metabolites in CSF was crucial for the identification of index cases. Response to therapy was variable but in general unsatisfactory except in a family with GTP cyclohydrolase deficiency. Conclusions: These disorders should be considered in the differential diagnosis of paediatric neurodegenerative diseases, in order to allow an adequate therapeutic trial that can favor prognosis

Molybdenum Cofactor Deficiency. A Differential Diagnosis in a Newborn with Seizures

Descrevemos um lactente com doença neurológica grave caracterizada por convulsões mioclónicas e tónicas, com início no período neonatal, refractárias a vários anticonvulsivantes, assim como, tetraparésia espástica. A tomografia computorizada e a ressonância magnética cerebrais evidenciaram imagens de leucomalácia periventricular e, posteriormente, de atrofia cerebral progressiva e encefalomalácia quística. Os exames bioquímicos e o estudo da actividade enzimática permitiram o diagnóstico de défice do cofactor molibdénio. O défice do cofactor molibdénio é uma doença rara, autossómica recessiva, que se comporta como um défice combinado da sulfito oxidase e da xantina desidrogenase (ou xantina oxidase) alterando o metabolismo das purinas e da cisteína. A terapêutica é controversa e o prognóstico reservado. O nosso objectivo é relembrar esta patologia no diagnóstico diferencial das convulsões neonatais e da encefalopatia hipóxico- -isquémica, sobretudo quando os exames imagiológicos sugerem lesões de leucomalácia no recém-nascido de termo. Salientamos a importância deste diagnóstico diferencial, apesar do prognóstico pobre, devido à possibilidade de aconselhamento genético adequado e diagnóstico pré-natal
