ObjectiveThe aim of the study was to investigate symptoms of long-term central nervous system (CNS) toxicity in HIV-positive patients treated with efavirenz (EFV).
MethodsWe carried out a single-centre, cross-sectional case-control study comparing patients treated with EFV for at least 6 months with a matched control group. Self-administered, standardized questionnaires including the Depression, Anxiety and Stress Scales (DASS), the Cognitive Failures Questionnaire (CFQ) and a questionnaire on unusual dreams, insomnia, fatigue, dizziness, depersonalization and derealization were administered.
ResultsData for 32 matched pairs were analysed. Significantly higher total stress scores (P 5 0.008) were found in the EFV group. Of the patients in this group, 19% also reported severe to extremely severe levels of stress (P 5 0.014), indicating increased difficulty in relaxing, and being more irritable, impatient, agitated and easily upset. Nineteen per cent of patients treated with EFV also reported severe levels of anxiety (P 5 0.059) as assessed with the DASS scale. This patient group also reported a higher rate of unusual dreams (P 5 0.049). No significant differences between groups were found for measures of cognitive impairments, fatigue, dizziness, derealization or depersonalization.
ConclusionEFV-treated patients reported higher levels of severe stress and anxiety as well as a higher rate of unusual dreams than patients not treated with EFV. These differences may be an expression of persisting CNS side effects in patients who remain on EFV for a prolonged period.
Abstract:Objective: Interstitial lung disease (ILD) frequently complicates systemic sclerosis (SSc). Cyclophosphamide (CYC) is a promising immunosuppressive therapy for SSc-related ILD. Our objective was to investigate the effectiveness of an intravenous CYC (iv CYC) pulse regime in SSc-related ILD during treatment and thereafter.
Methods:In a prospective observational study ten consecutive patients with SSc-related ILD were treated with iv CYC in a pulse regime lasting from 6 to 24 months. Clinical status, pulmonary functional testing (PFT) and high resolution computed tomography (HRCT) of the chest were evaluated at enrolment and 6, 12 and 24 months thereafter. After treatment withdrawal, patients were followed up every 6 months with PFT and chest HRCT to monitor lung disease.Results: Clinical improvement was apparent in 8 out of 10 patients. The median values of forced vital capacity (FVC), forced expiratory volume in the first second (FEV1) and diffusion lung capacity for carbon monoxide (DLCO) as well as ground-glass pattern on HRCT did not change significantly after 6, 12 and 24 months of therapy. The follow-up continued in 8 out of 10 patients after treatment withdrawal for a median of 26.5 months (range: 12-48 months). The final median FVC was 54.5% of predicted value (interquartile range, IQR= 31.6%-94%). Only one patient suffered a FVC deterioration greater than 10%, even though less than 160 ml. The final median DLCO was 68% of predicted value (IQR=38.3-83.6%). Only 2 patients who developed pulmonary arterial hypertension deteriorated their DLCO values of more than 15%.Conclusions: An iv CYC pulse regimen over 24 months may stabilize pulmonary activity in patients with SSc-related ILD during the course of treatment and for a median of 26.5 months thereafter.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
