Abstract Background Although SARS-CoV-2 infection in Healthcare Workers (HCWs) is a public health concern, there little description of their longitudinal antibody response the presence or absence and symptoms. We followed HCWs an acute London hospital to measure seroconversion RNA detection at peak pandemic. Methods enrolled 200 patient-facing between 26 March 8 April 2020 collected twice-weekly self-administered nose throat swabs, symptom data monthly blood samples. Swabs were tested for by...

Objective: Excessive weight gain has been reported with integrase strand transfer inhibitors (INSTIs). We evaluated changes in virologically suppressed adults HIV who switched from non-INSTI regimens to raltegravir (RAL)-containing or dolutegravir (DTG)-containing antiretroviral therapy. Design: Retrospective single-centre cohort. Methods: Adults RAL DTG before between January 2015 and October 2017 were identified. Virologically suppressed, treatment-experienced (≥2 years) individuals, at...

Abstract Background The aims of this study were to identify common patterns comorbidities observed in people living with HIV (PLWH), using a data-driven approach, and evaluate associations between identified. Methods A wide range assessed PLWH participating 2 independent cohorts (POPPY: UK/Ireland; AGEhIV: Netherlands). presence/absence each comorbidity was determined mix self-reported medical history, concomitant medications, health care resource use, laboratory parameters. Principal...

Severe renal failure is a life-threatening complication of multiple myeloma. Aggressive treatment can reverse acute in many cases but the prognosis for those who require chronic replacement therapy not clear. We have reviewed these patients Brighton, Dulwich and Guy's Hospitals units. Twenty-three were treated total 385 months. Over half presented with end-stage required dialysis immediately. Fifteen died during study period actuarial survival was 45 per cent at one year; six survived longer...

Monocytes from human immunodeficiency virus (HIV) patients have an increased heterogeneity of phenotype and function. In a study 120 HIV we demonstrated that they normal monocyte differential counts but with progression the disease increasing proportion monocytes show phenotypic functional evidence for activation or maturation. A are larger, expression CD11b, HLA-DR, CD45 CD16. Concomitantly there was TNF-α, high constitutive synthesis PGE2 plasma IL-6 levels. This suggested exist more...

The value of immunoscintigraphy with technetium-99m (99Tcm) labelled anti-granulocyte monoclonal antibody (BW250/183) was studied prospectively in human immunodeficiency virus (HIV-1) antibody-positive patients presenting fever without localizing symptoms or signs. Twenty-three studies were performed 23 and the results 99Tcm-anti-granulocyte imaging compared definitive microbiological cytological diagnosis. Twenty-one had an infective cause pyrexia, one patient disseminated lymphoma Kaposi...
