RESUMEN

Patients lacking humoral response have been suggested to develop a less severe COVID-19, but there are some reports with a prolonged, relapsing or deadly course. From April 2020, there is growing evidence on the benefits of COVID-19 convalescent plasma (CCP) for patients with humoral immunodeficiency. Most of them had a congenital primary immunodeficiency or were on treatment with anti CD20 antibodies. We report on three patients treated in our hospital and review thirty-one more cases described in the literature. All patients but three resolved clinical picture with CCP. A dose from 200 to 800ml was enough in most cases. Antibody levels after transfusion were negative or low, suggesting consumption of them in SARS-CoV-2 neutralization. These patients have a protracted clinical course shortened after CCP. CCP could be helpful for patients with humoral immunodeficiency. It avoid relapses and chronification. CCP should be transfused as early as possible in patients with COVID-19 and humoral immunodeficiency.

Se ha sugerido que los pacientes carentes de respuesta inmune humoral desarrollan una forma menos severa de COVID-19, pero existen algunos casos de curso prolongado, recurrente o incluso mortal. Desde abril de 2020 existen evidencias de los beneficios del plasma de convalecientes de COVID-19 (PCC) en los pacientes con inmunodeficiencia humoral. La mayoría tienen una inmunodeficiencia congénita primaria o están recibiendo tratamiento con anticuerpos anti-CD20. Describimos tres pacientes con inmunodeficiencia humoral y COVID-19 tratados con PCC en nuestro centro y revisamos los 31 casos más descritos en la literatura. Todos resolvieron el cuadro clínico con PCC, salvo tres. Una dosis de 200-800 mL fue suficiente en la mayoría de los casos. Los niveles de anticuerpos tras la transfusión fueron negativos o bajos, sugiriendo el consumo de los mismos en la neutralización del SARS-CoV-2. Estos pacientes tienen un curso clínico prolongado que se acorta tras la administración del PCC. El PCC podría ser de utilidad en los pacientes con inmunodeficiencia humoral. Evita las recaídas y la cronificación de la COVID-19. El PCC debería transfundirse lo antes posible en los pacientes con COVID-19 e inmunodeficiencia humoral.(AU)

RESUMEN

BACKGROUND: Scale-up of hepatitis C virus (HCV) treatment for HIV/HCV coinfected individuals is occurring in Spain, the vast majority (> 85%) with a reported history of injecting drug use and a smaller population of co-infected men who have sex with men (MSM). We assess impact of recent treatment scale-up to people living with HIV (PLWH) and implications for achieving the WHO HCV incidence elimination target (80% reduction 2015-2030) among PLWH and overall in Andalusia, Spain, using dynamic modeling. METHODS: A dynamic transmission model of HCV/HIV coinfection was developed. The model was stratified by people who inject drugs (PWID) and MSM. The PWID component included dynamic HCV transmission from the HCV-monoinfected population. The model was calibrated to Andalusia based on published data and the HERACLES cohort (prospective cohort of HIV/HCV coinfected individuals representing > 99% coinfected individuals in care in Andalusia). From HERACLES, we incorporated HCV treatment among diagnosed PLWH of 10.5%/year from 2004 to 2014, and DAAs at 33%/year from 2015 with 94.8% SVR. We project the impact of current and scaled-up HCV treatment for PLWH on HCV prevalence and incidence among PLWH and overall. RESULTS: Current treatment rates among PLWH (scaled-up since 2015) could substantially reduce the number of diagnosed coinfected individuals (mean 76% relative reduction from 2015 to 2030), but have little impact on new diagnosed coinfections (12% relative reduction). However, DAA scale-up to PWLH in 2015 would have minimal future impact on new diagnosed coinfections (mean 9% relative decrease from 2015 to 2030). Similarly, new cases of HCV would only reduce by a mean relative 29% among all PWID and MSM due to ongoing infection/reinfection. Diagnosing/treating all PLWH annually from 2020 would increase the number of new HCV infections among PWLH by 28% and reduce the number of new HCV infections by 39% among the broader population by 2030. CONCLUSION: Targeted scale-up of HCV treatment to PLWH can dramatically reduce prevalence among this group but will likely have little impact on the annual number of newly diagnosed HIV/HCV coinfections. HCV microelimination efforts among PWLH in Andalusia and settings where a large proportion of PLWH have a history of injecting drug use will require scaled-up HCV diagnosis and treatment among PLWH and the broader population at risk.

RESUMEN

Introducción. La monoterapia con inhibidores de la proteasa potenciados con ritonavir (IP/r): darunavir (DRV/r) o lopinavir (LPV/r), sólo está contemplada en las principales guías de tratamiento en pacientes pretratados para evitar toxicidad asociada a inhibidores de transcriptasa inversa análogos de nucleósidos/nucleótidos (ITIAN), reducir costes y simplificar el tratamiento antirretroviral (TAR). Para iniciar una monoterapia basada en IP/r según las guías GESIDA del año 2016, es necesario que el paciente cumpla los siguientes criterios: ausencia de hepatitis crónica B, carga viral plasmática (CVP) (<50 copias/ mL) durante al menos 6 meses y ausencia de mutaciones en el gen de la proteasa o fracasos virológicos (FV) previos a IP/r. Actualmente no hay estudios que evalúen la eficacia y seguridad de una monoterapia con darunavir/cobicistat (DRV/COBI). Material y Métodos. Se trata de un estudio prospectivo en el que se incluyeron pacientes VIH pretratados con DRV/r en monoterapia que cambiaron a una monoterapia con DRV/ COBI. El objetivo de nuestro estudio es describir la efectividad y seguridad de la monoterapia con DRV/COBI. Resultados. Se estudiaron 78 pacientes. Los pacientes tuvieron una mediana de 31,29 (6-74,82) meses de monoterapia con DRV/r previo al cambio a DRV/COBI en monoterapia. Nueve de los 78 pacientes desarrollaron 'blips' (CVP: 50-200 copias/ml) y cuatro pacientes tuvieron CVP≥ 200 copias/mL. Un 83,3% (65/78) se mantuvieron con CVP indetectable. En cuanto a la seguridad, no hubo diferencias importantes en el perfil lipídico, función hepática (transaminasas) y función renal entre DRV/r y DRV/COBI en monoterapia. Conclusiones. DRV/COBI en monoterapia, parece ser efectivo y seguro (perfil lipídico, hepático y renal). Sin embargo, deberían diseñarse estudios específicos que comparasen DRV/r vs. DRV/COBI en monoterapia para comprobar estos resultados (AU)


Introduction. Ritonavir-boosted protease inhibitor (IP/r) monotherapy: darunavir/ritonavir (DRV/r) or lopinavir/ritonavir (LPV/r) monotherapy is only provided in the major treatment guidelines in pretreated patients to prevent toxicity associated with nucleoside/nucleotide reverse transcriptase inhibitor (NRTI), reduce costs and simplify antiretroviral treatment. To start IP/r monotherapy, according to GESIDA guidelines 2016, patients need to meet the following criteria: absence of chronic hepatitis B, plasma viral load <50 copies/ mL for at least 6 months and absence of protease inhibitors mutations or previous virologic failures to IP/r. Currently, there are no studies that evaluate the efficacy and safety of darunavir/cobicistat (DRV/COBI) monotherapy. Methods. This prospective study analyzed pretreated HIV patients with DRV/r monotherapy that were switched to DRV/ COBI monotherapy. The aim of the study is to describe the effectiveness and safety of the DRV/COBI monotherapy. Results. Seventy-eight patients were evaluated. Patients had a median of 31.29 months of DRV/r monotherapy before DRV/COBI monotherapy. Nine of the 78 patients developed 'blips' (plasma viral load: 50-200 copies/ml) and four patients had plasma viral load ≥200 copies/mL. An 83.3% (65/78) of the patients remained with undetectable plasma viral load. As for safety, there were no significant differences in lipid profile, liver function (transaminases) and renal function between DRV/r and DRV/COBI monotherapy. Conclusions. DRV/COBI monotherapy seems to be effective and safe (lipid profile, liver and kidney function). However, it would be necessary to design specific studies comparing DRV/r vs DRV/COBI monotherapy to confirm these results (AU)

RESUMEN

BACKGROUND: Information concerning lipid disturbances in HIV-infected women on antiretroviral therapy (ART) is scarce. The objective of the study is to describe the lipid profile in a large cohort of HIV-infected women on contemporary ART and analyse differences between regimes and patient's characteristics. METHODS: Observational, multicentre, cross-sectional study from the Spanish VACH Cohort. 922 women on stable ART without lipid-lowering treatment were included. RESULTS: Median age was 42 years, median CD4 lymphocyte count was 544 cells/mm3, and 85.6% presented undetectable HIV-1 viral load. Median total cholesterol (TC) was 189 mg/dL (interquartile range, IQR, 165-221), HDL cholesterol 53 mg/dL (IQR, 44-64), LDL cholesterol 108 mg/dL (IQR, 86-134), and triglycerides 116 mg/dL (IQR, 85-163). Mean accumulated time on ART was 116 months; 47.4% were on NNRTI-based regimes, 44.7% on PI, and 6.7% on only-NRTI therapy. 43.8% were also hepatitis C (HCV) coinfected. Patients on PI treatment presented higher TC/HDL ratio than those on NNRTI (p < 0.001). Significantly higher HDL values were observed in NNRTI-treated patients. HCV-coinfected patients presented lower TC/HDL ratio than the non HCV-coinfected. In multivariate analysis, factors independently associated with TC/HDL ratio were age, triglyceride levels and HCV co-infection. PI treatment presented a non-significant association with higher TC/HDL ratio. CONCLUSIONS: In HIV-infected women, the NNRTI-based ART is associated with a better lipid profile than the PI-based. Factors unrelated to ART selection may also exert an independent, significant influence on lipids; in particular, age, and triglyceride levels are associated with an increased TC/HDL ratio while HCV co-infection is associated with a reduced TC/HDL ratio.
