RESUMEN
INTRODUCTION: Alzheimer disease (AD) is the most common cause of dementia and is considered one of the main causes of disability and dependence affecting quality of life in elderly people and their families. Current pharmacological treatment includes acetylcholinesterase inhibitors (donepezil, galantamine, rivastigmine) and memantine; however, only one-third of patients respond to treatment. Genetic factors have been shown to play a role in this inter-individual variability in drug response. DEVELOPMENT: We review pharmacogenetic reports of AD-modifying drugs, the pharmacogenetic biomarkers included, and the phenotypes evaluated. We also discuss relevant methodological considerations for the design of pharmacogenetic studies into AD. A total of 33 pharmacogenetic reports were found; the majority of these focused on the variability in response to and metabolism of donepezil. Most of the patients included were from Caucasian populations, although some studies also include Korean, Indian, and Brazilian patients. CYP2D6 and APOE are the most frequently studied biomarkers. The associations proposed are controversial. CONCLUSIONS: Potential pharmacogenetic biomarkers for AD have been identified; however, it is still necessary to conduct further research into other populations and to identify new biomarkers. This information could assist in predicting patient response to these drugs and contribute to better treatment decision-making in a context as complex as ageing.

INTRODUCTION AND OBJECTIVE: The fundus oculi is useful for observation of the interior of the eye and the retina. This study establishes a relationship between patients with established cerebral infarcts and the results observed in their fundi. PATIENTS AND METHODS: A retrospective study of the clinical histories of 177 patients seen in the rehabilitation department over a period of one year. RESULTS: The patients were aged between 29 and 85 years. The majority were men; 101 patients (57.06%) had systolic-diastolic arterial hypertension. On study of the fundus oculi there was a predominance of alterations of the blood vessels of the retina due to vascular sclerosis (93.1%) but only 24.4% had frank alterations caused by arterial hypertension. CONCLUSIONS: We found a slight relation between arterial hypertension and the alterations observed in the fundus oculi of these patients.

A solid phase immunoradiometric assay (IRMA) for quantification of bovine albumin fraction V (Bov.Alb.FV) in antileptospirosical Cuban vaccine vaxSpiral is described in the present work. Anti-Bov.Alb.FV IgG raised against rabbit purified by affinity chromatography was used as first antibody. Anti-rabbit IgG labeled by Chloromine-T reaction was used as a tracer and the method has demonstrated to be sensitive with high intra- and inter-assay reproducibility. Eight lots of vaccinal antigens were evaluated and in all of the cases, the bovine albumin fraction V concentration was lower than 1 microgram/mL, as the World Health Organization (WHO) establishes. This IRMA is a simple and sensitive assay and could be used as control method for all human vaccines that use Bov.Alb.FV in their production process, even cellular vaccines.
