Thirty-day readmission rates in a cohort of people living with HIV in southern Brazil, 2015 to 2017.

BACKGROUND: The intense use of antiretroviral therapy (ART) has reduced morbidity and mortality of HIV infection. In Brazil, the specific contribution of diseases related to HIV infection leading to hospital admission and readmission is not well known. AIMS: The study aimed to determine the clinico-epidemiological profile, 30-day readmission rate, and factors associated with this outcome in a cohort of adults with HIV infection in southern Brazil. METHODS: Unicentric retrospective cohort, with data collection through the review of medical records and databases. RESULTS: We analyzed 574 index hospitalizations and 451 individuals. Of these, 57.6% were men and the mean (±SD) age was 42.2 ± 12.3 years. Only 43.4% used ART regularly and low CD4 count and high frequency of detectable viral load were observed. HIV/AIDS-related diseases were identified in 55.2%, and tuberculosis was the most frequent etiology leading to index hospitalization. We found a 30-day readmission rate of 11.5% and hospitalization for HIV/AIDS-related illness was associated with a higher risk for the outcome. CONCLUSIONS: These findings highlight the need to expand resources for prevention, early diagnosis, retention, and treatment of people living with HIV in the region to reduce HIV/AIDS-associated diseases and possibly minimize consequent hospital readmission of these individuals.

Is Ataxia an Underestimated Symptom of Huntington's Disease?

Background: Huntington's disease (HD) is a progressive disorder characterized by motor, cognitive and psychiatric features. Cerebellar ataxia is classically considered as uncommon in HD clinical spectrum. Objective: To determine the prevalence of cerebellar ataxia in patients with HD, both in the early and in the late stages of HD. Methods: Seventy-two individuals considered eligible were assessed by two trained doctors, applying the Scale for Assessment and Rating of Ataxia (SARA) and Brief Ataxia Rating Scale (BARS) for ataxia, the Unified Huntington's Disease Rating Scale (UHDRS) and also, Barthel Index (BI), in order to evaluate functional capacity. Results: Fifty-one patients (70.8%) presented with clinical ataxia at the time of examination (mean time of disease was 9.1 years). Six (8.33%) patients presented with cerebellar ataxia as first symptom. When stratified according to time of disease, a decline in the presence of chorea (p = 0.032) and an increase in cognitive deficit (p = 0.023) were observed in the patients as the disease progressed. The presence of ataxia was associated with longer duration of illness and severity of illness (UHDRS) (p < 0.0001), and shorter Barthel (less functionality) (p = 0.001). Conclusions: Cerebellar involvement may play an important role in natural history of brain degeneration in HD. The presence of cerebellar ataxia in HD is relevant and it may occur even in early stages, and should be included as part of the motor features of the disease.
