ABSTRACT BACKGROUND: The World Health Organization has declared that a pandemic situation exists in relation to the disease caused by the new coronavirus, COVID-19. So far, the absence of a vaccine against the new coronavirus has led people worldwide to seek various therapeutic alternatives, including use of cholecalciferol. DESIGN AND SETTING: Narrative review developed by a research group at a public university in Recife (PE), Brazil. METHODS: We searched the literature on the use of cholecalciferol for prevention or treatment of COVID-19, using the MEDLINE and LILACS databases, with the keywords “vitamin D”, “cholecalciferol”, “SARS-CoV-2”, “COVID-19” and “coronavirus”, from January 1, 2020, to June 10, 2020. Narrative reviews, cohort studies and ecological studies were selected. RESULTS: We retrieved 32 references, of which 8 were considered eligible for intensive review and critical analysis. These comprised five narrative reviews, two observational studies and one protocol proposal. Most of the studies selected reported positive effects from use of vitamin D for prevention or treatment of COVID-19. However, there was little quantitative data to assess the real impact of using this vitamin as an intervention against this disease. CONCLUSIONS: Current studies on vitamin D used for purposes other than bone health promotion cannot be taken as support to justify its use in a disease as recent as COVID-19. Studies of greater robustness, with higher levels of clinical evidence, need to be conducted. Rational use of this vitamin needs to be ensured, thereby minimizing the impacts on the patient and the public healthcare system.

Resumo Este trabalho teve como objetivo verificar a prevalência do uso de medicamento potencialmente inapropriado (MPI) para idosos residentes em Instituições de Longa Permanência para Idosos (ILPI), assim como os tipos de medicamentos e seus fatores associados. Trata-se de estudo transversal realizado em 10 ILPI da cidade do Natal, entre outubro e dezembro de 2013. Os medicamentos inapropriados foram classificados de acordo com os Critérios de Beers da American Geriatric Society 2015. Foram analisadas variáveis sociodemográficas, relacionadas à ILPI e às condições de saúde. Para as análises univariada e multivariada entre a variável principal (uso de MPI) e as demais foi utilizada a regressão de Poisson. A amostra foi composta por 321 idosos e, destes, 304 utilizavam medicamentos. A prevalência de uso de MPI foi de 54,6% (IC 95%: 48,9-60,2) e no modelo final esteve associada à polifarmácia e à demência. As classes terapêuticas de MPI mais identificadas foram antipsicóticos e benzodiazepínicos. O estudo revelou alta prevalência de MPI entre os idosos das ILPI, configurando a necessidade de adoção de indicadores do uso destes medicamentos e a implantação de estratégias que tornem a farmacoterapia mais segura e adequada aos idosos.

Abstract This study aimed to verify the prevalence of the use of Potentially Inappropriate Medications (PIM) for elderly living in Long-Term Care Institutions for the Elderly (LTCIE), as well as the types of medications and their associated factors. This is a cross-sectional study carried out in 10 LTCIEs in the city of Natal in the period October-December 2013. Potentially inappropriate medications were classified according to the 2015 American Geriatric Society Beers Criteria for Potentially Inappropriate Medication Use in Older Adults - 2015. Sociodemographic, LTCIE-related and health-related variables were considered. Univariate and multivariate analyses were performed between the primary variable (PIM use) and the independent variables using Poisson regression. The sample consisted of 321 older people, of whom 304 used medications. The prevalence of PIM use was 54.6% (95% CI: 48.9-60.2) and was associated with polypharmacy and dementia in the final model. The most common PIMs were antipsychotics and benzodiazepines. The study revealed a high prevalence of PIM use among the elderly of the LTCIEs, evidencing the need to adopt indicators on the use of these drugs and the implementation of strategies that make drug therapy safer and more adequate for older adults.

RESUMO Objetivo: associar medicamentos de uso contínuo com a presença de tontura em idosos institucionalizados. Métodos: trata-se de um estudo transversal realizado em 10 Instituições de longa permanência para idosos. Foram incluídos todos os idosos a partir de 60 anos que fossem capazes de deambular e que apresentassem bom nível cognitivo. Foram coletadas as medicações de uso contínuo e dados referentes à Instituição. Ao idoso, foi questionado se apresentou tontura no último ano. Para análise estatística, utilizou-se os testes do Qui-quadrado e Exato de Fisher para análise bivariada e regressão logística para análise múltipla stepwise forward, com nível de significância de 5%. Resultados: dos 92 idosos avaliados, 35 afirmaram terem apresentado tontura nos últimos 12 meses (23,8%). Foram associados à tontura os antiepilépticos (p=0,034, RR= 2,26, IC95% 1,06-4,78), anti-trombóticos (p=0,008, RR= 0,21, IC95% 0,07-0,67) e diuréticos (p=0,024, RR= 2,29, IC95% 1,11-4,70), ajustados pelos psicolépticos. Conclusão: a tontura nos idosos institucionalizados esteve associada ao uso crônico de anti-epilépticos e diuréticos.

ABSTRACT Purpose: to associate continuous use drugs with the presence of dizziness in institutionalized elderly people. Methods: a cross-sectional study performed in 10 nursing homes. People aged 60 years or older, able to walk and who presented good cognitive level were included in this study. Data on medications for continuous treatment and data referring to the Institution were collected. The elderly were asked if they had experienced dizziness in the previous year. The Chi-squared and Fisher exact tests were used for bivariate analysis and stepwise forward logistic regression to perform multiple analysis, with a significance level of 5%. Results: out of 92 elderly, 35 reported dizziness in the previous year (23.8%). The anti-epileptics (p=0.034, RR=2.26, CI95% 1.06-4.78), antithrombotics (p=0.008, RR=0.21, CI95% 0.07-0.67) and diuretics (p=0.024, RR=2.29, CI95% 1.11-4.70) were associated to dizziness, adjusted by psycholeptics. Conclusion: dizziness in these institutionalized elderly people was associated with the chronic use of anti-epileptics and diuretic drugs.
