Multivariate symptom analysis related to response to lorazepam treatment

Current Medical Research and Opinion

Abstract

In an attempt to explain the marked inter-trial differences in the percentage of patients reported to benefit from the anxiolytic agent lorazepam, a statistical analysis was carried out on the scores from a psychiatric symptom questionnaire, completed before and after treatment with lorazepam, by 69 psychiatric out-patients. Most of the patients presented with a mixture of different syndromes, with moderate to severe symptoms, and had already failed to respond to other treatment. Forty of the patients showed a favourable response to lorazepam. Multivariate analysis of the strength of 6 symptom clusters versus therapeutic response in this diagnostically heterogeneous patient sample revealed that, in addition to anxiety, there was a high relationship also between phobic and psychosomatic symptom scores and response to lorazepam. The relationship between depression scores and response was only of borderline significance, and that for hysteria and obsessionality was poor. It is suggested that one explanation of inter-trial differences in the percentages of patients improved by lorazepam may be that they are due to differences in the diagnostic composition of the patient populations studied.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Artificial Intelligence in Cardiac Imaging

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.
