Temporary COVID-19 hotels have been established in Italy to assist the homeless people that test positive for SARS-CoV-2 and require isolation. This observational study aimed to investigate the ...characteristics of the subjects who were isolated at the Casa tra Noi COVID-19 hotel in Rome between October 2020 and May 2021 and to estimate the duration of SARS-CoV-2 positivity according to their main socio-demographic, behavioural and clinical features.
Socio-demographic data, clinical history, and anamnestic data of guests were collected by the clinicians reviewing the medical documentation and face-to-face interviewing. Nasopharyngeal swabs were performed every 7 days and the presence of SARS-CoV-2 was assessed by RT-PCR. Median duration of SARS-CoV-2 positivity according to socio-demographic, behavioral factors and clinical condition was calculated.
The 196 guests (161 males, 82.1%) had a median age of 41 years (IQR: 30-53), and were mostly African (87, 44.4%). Only asymptomatic/paucisymptomatic infections were observed. Almost half of the individuals (84, 42.9%) were affected by at least one co-morbidity, the frequency of which was higher among women (57.1% vs. 39.8%, p=0.06). The date of the negative SARS-CoV-2 molecular test was known for 144 guests (73.5%). Among these, the median duration of positivity was 21 days (IQR: 14-26) and did not significantly vary with age, country of origin, smoking status, alcohol or drug abuse. Among the co-morbidities, only infectious diseases significantly modified the duration of positivity, which increased from 21 to 34 days (p=0.013).
Hotel guests were frequently affected by physical/mental co-morbidities. Duration of SARS-CoV-2 positivity was significantly prolonged only in individuals affected by an infectious disease.
Abstract
Objectives
To compare the long-term risk of treatment failure of dolutegravir-based ART in men and women in a real-life setting.
Patients and methods
Persons living with HIV (PLWH) from the ...ICONA cohort were included if they had started dolutegravir in a two- or three-drug regimen as ART-naive or as virologically controlled ART-experienced. The primary endpoint was time to treatment failure (virological/clinical failure or dolutegravir discontinuation). Secondary endpoints were: time to dolutegravir discontinuation due to toxicity and to neuropsychiatric adverse events; and time to virological failure. Cox regression analyses focused on differences in outcomes by sex.
Results
A total of 2304 PLWH (15% women) initiated dolutegravir-based therapy from ART-naive, and 1916 (19.8% women) while experienced. After a median follow-up of 2.2 (IQR: 0.9–3.9) years in ART-naive and 2.4 (IQR: 1.1–4.3) years in experienced, the 4-year cumulative probability of treatment failure was 33% (95% CI 30.5–35.1) and 20% (95% CI 17.8–22.3), respectively. In the multivariable analyses, in ART-naive the risk of treatment failure was higher for women, but not different after excluding women discontinuing dolutegravir for pregnancy concerns. We also observed a higher risk of discontinuation for toxicity in women (ART-naives: Adjusted Hazard Ratio (AHR): 1.56%; 95% CI: 1.03–2.37; ART-experienced: AHR: 1.53%; 95% CI: 1.01–2.32), although the absolute 4-year probability was low: 7.7% (95% CI 6.5–9.2) in ART-naive and 8.3% (95% CI 6.9–9.9) in experienced.
Conclusions
In our cohort of PLWH treated with dolutegravir-based regimens and followed up for up to 4 years, we observed a low risk of treatment failure and no evidence for a difference by sex, after excluding discontinuation due to pregnancy concerns. However, we observed a higher risk of dolutegravir discontinuation for toxicity in women.
