Fecal Microbiota Transplantation for People Living with Human Immunodeficiency Virus: A Scoping Review
The aim of this scoping review was to determine the characteristics of studies evaluating fecal microbiota transplantation (FMT), as well as its effects and safety as a therapeutic intervention for people living with human immunodeficiency virus (HIV). We conducted a scoping review following the methodology of the Joanna Briggs Institute. We searched the following databases: PubMed, Web of Science, Scopus, Embase, Cochrane Library, and Medline until September 19, 2021. Studies that used FMT in people living with HIV and explored its effects on the health of these people were included. Two randomized and 2 uncontrolled clinical trials with a total of 55 participants were included. Participants were well-controlled HIV-infected people. Regarding microbiota changes, three studies found significant post-FMT increases in
,
, α-diversity, Chao index, and/or Shannon index, and/or decreases in
. Regarding markers of intestinal damage, one study found a decrease in intestinal fatty acid binding protein post-FMT, and another study found an increase in zonulin. Other outcomes evaluated by the studies were as follows: markers of immune and inflammatory activation, markers of immunocompetence (CD4
, and CD8
T lymphocytes), and HIV viral load; however, none showed significant changes. Clinical outcomes were not evaluated by these studies. Regarding the safety of FMT, only mild adverse events were appreciated. No serious adverse event was reported. The clinical evidence for FMT in people living with HIV is sparse. FMT appears to have good tolerability and, no serious adverse event has been reported so far. Further clinical trials and evaluation of clinically important biomedical outcomes for FMT in people living with HIV are needed

549. Clinical Characteristics and Outcomes of Patients with COVID-19 treated with Convalescent Plasma in Miami, Florida
AbstractBackgroundThe Coronavirus disease of 2019 (COVID-19) global health crisis caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in unprecedented mortality, impacted society, and strained healthcare systems, yet sufficient data regarding treatment options are lacking. Convalescent plasma, used since 1895 for infectious disease outbreaks, offers promise as a treatment option for COVID-19.MethodsThis is a retrospective study of patients diagnosed by a nasopharyngeal swab SARS-CoV-2 reverse transcriptase–polymerase chain reaction (RT-PCR), who received convalescent plasma between April to June 2020 at two large hospitals in Miami, Florida, as part of the US FDA Expanded Access Program for COVID-19 convalescent plasma (CCP).ResultsA total of 23 patients received CCP, 13 (57%) had severe COVID-19 disease, while 8 (35%) had critical or critical with multiorgan dysfunction. Median time of follow up was 26 (range, 7–79) days. Overall, 11 (48%) survived to discharge, 6 (26%) died, while 6 (26%) are currently hospitalized. All deaths reported were due to septic shock from secondary infections. 15 (65%) showed improvement in oxygen requirements 7 days post CCP transfusion. Measured inflammatory markers, c-reactive protein, lactate dehydrogenase, ferritin and d-dimer improved 7 days post transfusion in 13 (57%) patients. No adverse events due to the transfusion were reported. 10 (43.4%) patients had a negative SARS-CoV-2 RT-PCR at a median of 14.5 (range, 4–31) days after receiving convalescent plasma.ConclusionAdministration of convalescent plasma was found to be safe, with favorable outcomes in this small cohort of relatively high acuity patients. Larger studies including control arms are needed to establish the efficacy of convalescent plasma on clinical and virologic outcomes for patients with COVID-19.TableDisclosuresAll Authors: No reported disclosure
