What this Trial Is About

Researchers are studying leptospirosis, a bacterial infection, to understand if complement factor I (CFI) can predict lung complications and if treatments like plasma transfusion, hemoperfusion, and extracorporeal membrane oxygenation (ECMO) can help manage the disease and improve survival. This Phase 2 trial aims to find out whether these treatments reduce lung damage and mortality in patients with complicated leptospirosis. Participants may receive different treatments based on their assigned group: plasma transfusion involves receiving four plasma units over two days; hemoperfusion uses a device to filter harmful substances from the blood over at least three days; ECMO is provided if lung function worsens. All participants receive standard care such as antibiotics and fluids, and some may receive ECMO as rescue treatment depending on lung severity scores. During the study, participants give blood samples to measure CFI levels. Researchers monitor hospital stay length, lung and kidney complications, use of respiratory support, and survival for an average of three years. The study tracks various health measures including respiratory status, dialysis needs, and intensive care duration to evaluate treatment effects and safety throughout hospitalization and follow-up.

Your Study Journey

Screening

Duration - 2 to 4 weeks

Participants are screened for eligibility to participate in the trial.

1 visit (in-person)

Treatment

Duration - Duration of hospital stay

Participants receive one of the following interventions based on their assigned group: prophylactic plasma transfusion administered intravenously over two consecutive days; hemoperfusion sessions lasting 2 to 2.5 hours repeated for at least three days; or conventional therapy including antibiotics and supportive care. Some participants may receive extracorporeal membrane oxygenation (ECMO) if clinical criteria are met during their hospital stay.

Daily visits during hospitalization

Follow-up

Duration - Up to 3 years

Participants are monitored after treatment completion for clinical outcomes including survival, pulmonary and renal function, and need for supportive therapies.

Periodic follow-up visits over up to 3 years
