Clinical glaucoma treatment at a university hospital: monthly cost and financial impact

Purpose: To verify the social characteristics and the impact of glaucoma treatment on the familial income of patients followed at a university hospital. Methods: One hundred and forty six glaucomatous patients were interviewed at the Hospital das Clínicas da Universidade de Campinas to evaluate their social economic profile. The questionnaire investigated the occupation, the individual and familial income, as well as the type and frequency of the antiglaucomatous drugs used by each patient. Knowing the monthly cost of antiglaucomatous drugs available in Brazil, we were able to calculate the monthly cost of glaucoma treatment and the percentage of committed familial income. Results: The mean monthly cost of glaucoma treatment was 36.09 ± 31.99 reais, which corresponded to 15.5% of the familial income. Thirty-six (24%) patients had 25 percent or more of the familial income spent on their treatment. Sixty-six (45.2%) patients had difficulty in buying their medications. Factors associated with this difficulty included low familial income (p=0.0001), and high percentage of the income used to buy the drugs (p=0.0002). Conclusion: The cost of glaucoma treatment is high compared to the income of patients treated at a public institution. This population has a low familial income, of which a high percentage is required to acquire antiglaucoma medications. We suggest that these patients may be at risk for low compliance due to economical limitations.Objetivo: Verificar características sociais e o impacto do custo do tratamento antiglaucomatoso na renda familiar entre pacientes do Serviço de Oftalmologia de hospital universitário. Métodos: Realizou-se estudo transversal entre 146 pacientes do Setor de Glaucoma do Hospital das Clínicas da Universidade Estadual de Campinas (UNICAMP), aplicando-se um questionário por entrevista. Foram investigadas as variáveis: escolaridade, exercício de atividade profissional, renda própria e familiar, quantidade e tipo de medicações e tempo de tratamento antiglaucomatoso. A partir do custo mensal de medicações antiglaucomatosas disponíveis no Brasil e dos dados obtidos na entrevista, calculou-se o custo médio mensal do tratamento clínico e a porcentagem da renda familiar destinada à aquisição desses medicamentos. Além disto, investigaram-se fatores associados à dificuldade de aquisição da medicação. Resultados: O custo mensal médio do tratamento antiglaucomatoso foi de 36,09 ± 31,99 reais, o que correspondeu a 15,5% da renda familiar média. Aproximadamente 24,0% dos pacientes tiveram 25% ou mais de sua renda comprometida com o tratamento e 45,2% relataram dificuldade de adquirir a medicação em algum momento do tratamento. Os principais fatores associados à dificuldade de compra da medicação foram a reduzida renda familiar (p=0,0001) e a expressiva parcela da renda familiar destinada ao tratamento (p=0,0002). Conclusões: O tratamento do glaucoma apresentou custo elevado em relação à renda familiar da amostra. Evidenciou-se tratar de pacientes de baixa renda, destinada em boa parte ao tratamento do glaucoma. Admite-se que possam apresentar maior risco de baixa adesão ao tratamento antiglaucomatoso por dificuldades para adquirirem a medicação.29930

Neuroimaging in Hereditary Spastic Paraplegias: Current Use and Future Perspectives

Hereditary spastic paraplegias (HSP) are a large group of genetic diseases characterized by progressive degeneration of the long tracts of the spinal cord, namely the corticospinal tracts and dorsal columns. Genotypic and phenotypic heterogeneity is a hallmark of this group of diseases, which makes proper diagnosis and management often challenging. In this scenario, magnetic resonance imaging (MRI) emerges as a valuable tool to assist in the exclusion of mimicking disorders and in the detailed phenotypic characterization. Some neuroradiological signs have been reported in specific subtypes of HSP and are therefore helpful to guide genetic testing/interpretation. In addition, advanced MRI techniques enable detection of subtle structural abnormalities not visible on routine scans in the spinal cord and brain of subjects with HSP. In particular, quantitative spinal cord morphometry and diffusion tensor imaging look promising tools to uncover the pathophysiology and to track progression of these diseases. In the current review article, we discuss the current use and future perspectives of MRI in the context of HSP

FACTORS ASSOCIATED TO ADHERENCE TO DIFFERENT TREATMENT SCHEMES WITH MEGLUMINE ANTIMONIATE IN A CLINICAL TRIAL FOR CUTANEOUS LEISHMANIASIS

The favorable outcome of the treatment of a disease is influenced by the adherence to therapy. Our objective was to assess factors associated with adherence to treatment of patients included in a clinical trial of equivalence between the standard and alternative treatment schemes with meglumine antimoniate (MA) in the treatment of cutaneous leishmaniasis (CL), in the state of Rio de Janeiro. Between 2008 and 2011, 57 patients with CL were interviewed using a questionnaire to collect socioeconomic data. The following methods were used for adherence monitoring: counting of vial surplus, monitoring card, Morisky test and modified Morisky test (without the question regarding the schedule); we observed 82.1% (vial return), 86.0% (monitoring card), 66.7% (Morisky test) and 86.0% (modified Morisky test) adherence. There was a strong correlation between the method of vial counting and the monitoring card and modified Morisky test. A significant association was observed between greater adherence to treatment and low dose of MA, as well as with a lower number of people sleeping in the same room. We recommend the use of the modified Morisky test to assess adherence to treatment of CL with MA, because it is a simple method and with a good performance, when compared to other methods

Association of Genetic Variants With Primary Open-Angle Glaucoma Among Individuals With African Ancestry.

Importance:Primary open-angle glaucoma presents with increased prevalence and a higher degree of clinical severity in populations of African ancestry compared with European or Asian ancestry. Despite this, individuals of African ancestry remain understudied in genomic research for blinding disorders. Objectives:To perform a genome-wide association study (GWAS) of African ancestry populations and evaluate potential mechanisms of pathogenesis for loci associated with primary open-angle glaucoma. Design, Settings, and Participants:A 2-stage GWAS with a discovery data set of 2320 individuals with primary open-angle glaucoma and 2121 control individuals without primary open-angle glaucoma. The validation stage included an additional 6937 affected individuals and 14 917 unaffected individuals using multicenter clinic- and population-based participant recruitment approaches. Study participants were recruited from Ghana, Nigeria, South Africa, the United States, Tanzania, Britain, Cameroon, Saudi Arabia, Brazil, the Democratic Republic of the Congo, Morocco, Peru, and Mali from 2003 to 2018. Individuals with primary open-angle glaucoma had open iridocorneal angles and displayed glaucomatous optic neuropathy with visual field defects. Elevated intraocular pressure was not included in the case definition. Control individuals had no elevated intraocular pressure and no signs of glaucoma. Exposures:Genetic variants associated with primary open-angle glaucoma. Main Outcomes and Measures:Presence of primary open-angle glaucoma. Genome-wide significance was defined as P < 5 × 10-8 in the discovery stage and in the meta-analysis of combined discovery and validation data. Results:A total of 2320 individuals with primary open-angle glaucoma (mean [interquartile range] age, 64.6 [56-74] years; 1055 [45.5%] women) and 2121 individuals without primary open-angle glaucoma (mean [interquartile range] age, 63.4 [55-71] years; 1025 [48.3%] women) were included in the discovery GWAS. The GWAS discovery meta-analysis demonstrated association of variants at amyloid-β A4 precursor protein-binding family B member 2 (APBB2; chromosome 4, rs59892895T>C) with primary open-angle glaucoma (odds ratio [OR], 1.32 [95% CI, 1.20-1.46]; P = 2 × 10-8). The association was validated in an analysis of an additional 6937 affected individuals and 14 917 unaffected individuals (OR, 1.15 [95% CI, 1.09-1.21]; P < .001). Each copy of the rs59892895*C risk allele was associated with increased risk of primary open-angle glaucoma when all data were included in a meta-analysis (OR, 1.19 [95% CI, 1.14-1.25]; P = 4 × 10-13). The rs59892895*C risk allele was present at appreciable frequency only in African ancestry populations. In contrast, the rs59892895*C risk allele had a frequency of less than 0.1% in individuals of European or Asian ancestry. Conclusions and Relevance:In this genome-wide association study, variants at the APBB2 locus demonstrated differential association with primary open-angle glaucoma by ancestry. If validated in additional populations this finding may have implications for risk assessment and therapeutic strategies
