RESUMO
Immunocompromised patients with leukemia/lymphoma often have a suboptimal response to vaccination against SARS-CoV-2 and, if infected, can develop a persistent infection.SARS-CoV-2 PCR was performed on nasopharingeal swabs and serum IgG anti-SARS-CoV-2 trimeric spike glycoprotein antibodies were measured during persistence of infection. Treatment with a combination of nirmatrelvir/ritonavir plus sotrovimab led to viral clearance in three patients with leukaemia or lymphoma with persistent SARS-CoV-2 and negative SARS-CoV-2 antibody tests. No standardized treatments for persistent infection with SARS-CoV-2 infection are available. We have reported the viral clearance in two immunocompromised patients treated with antiviral drug nirmatrelvir/ritonavir and monoclonal antibody sotrovimab. We suggest that this strategy should be tested in clinical trials to find the right strategy for a clinical problem with public health implications to SARS-CoV-2 evolution and immune escape in these sub-set of patients.

To assess the potency, efficacy and toxicity of abacavir/lamivudine (ABC/3TC) versus tenfovir/emcitrabine (TDF/FTC) with efavirenz (EFV) in naive patients with HIV infection a prospective observational study was carried out to evaluate immunovirological parameters every three months and metabolic parameters every six months. In all, 21 patients were enrolled (10 on ABC/3TC and 11 on TDF/FTC). Fisher's test revealed no statistically significant difference between the two arms in terms of immunological recovery and control of viral replication. For metabolic parameters at week 48 no statistically significant differences were noted between the two arms. The two ABC/3TC and TDF/FTC backbones showed the same potency; ABC had a more negative impact on metabolic parameters without statistical power.
