ABSTRACT

Trauma and stressor-related symptoms have been frequently reported during the COVID-19 pandemic. Few studies compare post-traumatic stress symptoms (PTSS) between patients and non-infected controls. Using data from an ongoing natural history study of COVID-19, this study compared PTSS between patients infected with SARS-CoV-2 during the first year of the pandemic and controls. Within the COVID-19 patient cohort, we also compared PTSS between patients with and without post-COVID conditions, also known as post-acute sequelae of SARS-CoV-2 infection (PASC). This study also examined the association of PTSS with trait resilience and prior trauma exposure. PTSS were assessed using the Impact of Event Scaled-Revised (IES-R), which has a validated probable PTSD cutoff (score [≥]33). The results showed that patients (n=131) reported significantly higher IES-R scores than controls (n=82) and had significantly higher odds of having scores indicative of PTSD [AOR: 4.17 p: 0.029]. IES-R scores among PASC patients (n=68) were significantly elevated compared to patients without PASC (n=63) and PASC patients did not have higher odds for probable PTSD [AOR: 2.60; p: 0.14]. Trait resilience was associated with lower PTSS. These findings help characterize the mental health impact of the COVID-19 illness experience and highlight elevated PTSS in patients with persistent post-COVID conditions.

ABSTRACT

ABSTRACT Background Drug regimens which include intensified antibiotics alongside effective anti-inflammatory therapies may improve outcomes in Tuberculous Meningitis (TBM). Safety data on their use in combination and in the context of HIV is needed to inform clinical trial design. Methods We conducted a phase 2 open-label parallel-design RCT to assess safety of high-dose rifampicin, linezolid and aspirin in HIV-associated TBM. Participants were randomised (1.4:1:1) to three treatment arms (arm 1, standard of care (SOC); arm 2 SOC + additional rifampicin (up to 35mg/kg/day)) + linezolid 1200mg/day reducing after 28/7 to 600mg/day; arm 3, as per arm 2 + aspirin 1000mg/day) for 56 days, when the primary outcome of adverse events of special interest (AESI) or death was assessed. Results 52 participants were randomised. 59% had mild disease (MRC Grade 1) vs 39% (Grade 2) vs 2% (Grade 3). 33% of participants had microbiologically-confirmed TBM; vs 41% ‘possible’ or 25% ‘probable’. AESI or death occurred in 10/16 (arm 3) vs 4/14 (arm 2) vs 6/20 (arm 1) ( p=0 . 083 ). The cumulative proportion of AESI or death (Kaplan-Meier method) demonstrated worse outcomes in arm 3 vs arm 1 ( p=0 . 04 ), however only one event in arm 3 was attributable to aspirin and was mild. There was no difference in efficacy (Modified Rankin Scale) at day 56 between the three arms. Conclusions High-dose rifampicin and adjunctive linezolid can safely be added to SOC in HIV-associated TBM. Larger studies are required to evaluate whether potential toxicity associated with these interventions, particularly aspirin, is outweighed by mortality or morbidity benefit. SUMMARY In this phase 2a randomised control trial we demonstrate that high-doserifampicin and adjunctive linezolid is safe in adult HIV-associated tuberculous meningitis. Larger studies are required to evaluate potential toxicity with aspirin, in relation to benefit on morbidity and mortality.
