Treatment of COVID-19 with convalescent plasma in patients with humoral immunodeficiency - Three consecutive cases and review of the literature.

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)

Impact of HIV on the survival of hepatocellular carcinoma in hepatitis C virus-infected patients.

BACKGROUND: Previous studies have suggested that hepatocellular carcinoma (HCC) has an aggressive presentation and a shorter survival in people with HIV (PWH). This could be due to later diagnosis or lower rates of HCC treatment, and not to HIV infection itself. AIM: :: To assess the impact of HIV on HCC survival in hepatitis C virus (HCV)-infected patients. METHODS: Multicenter cohort study (1999-2018) of 342 and 135 HCC cases diagnosed in HIV/HCV-infected and HCV-monoinfected patients. Survival after HCC diagnosis and its predictors were assessed. RESULTS: HCC was at Barcelona-Clinic Liver-Cancer (BCLC) stage 0/A in 114 (33%) HIV/HCV-coinfected and in 76 (56%) HCV-monoinfected individuals (P < 0.001). Of them, 97 (85%) and 50 (68%) underwent curative therapies (P = 0.001). After a median (Q1-Q3) follow-up of 11 (3-31) months, 334 (70%) patients died. Overall 1 and 3-year survival was 50 and 31% in PWH and 69 and 34% in those without HIV (P = 0.16). Among those diagnosed at BCLC stage 0/A, 1 and 3-year survival was 94 and 66% in PWH whereas it was 90 and 54% in HIV-negative patients (P = 0.006). Independent predictors of mortality were age, BCLC stage and α-fetoprotein levels. HIV infection was not independently associated with mortality [adjusted hazard ratio (AHR) 1.57; 95% confidence interval: 0.88-2.78; P = 0.12]. CONCLUSION: HIV coinfection has no impact on the survival after the diagnosis of HCC in HCV-infected patients. Although overall mortality is higher in HIV/HCV-coinfected patients, this seem to be related with lower rates of early diagnosis HCC in HIV-infected patients and not with HIV infection itself or a lower access to HCC therapy.

Brief Report: Response to Hepatitis A Virus Vaccine in HIV-Infected Patients Within a Retrospective, Multicentric Cohort: Facing Hepatitis A Outbreaks in the Clinical Practice.

BACKGROUND: Various recent outbreaks of hepatitis A virus (HAV) have been described in men who have sex with men despite the availability of an effective vaccine. This study aimed to determine the current rates of seroconversion after receiving HAV vaccine (HAV-V) in HIV-infected patients under real-life conditions. SETTING: Patients were selected from a Southern Spanish multicentric cohort of HIV-infected subjects. METHODS: Retrospective analysis of all patients who received 2 doses (standard scheme) from April 2008 to May 2016 or from June 2016 to February 2018 facing an HAV outbreak with shortage of HAV-V, 1 single dose of HAV-V. Response to HAV-V was defined as positive anti-HAV IgG between 1 and 12 months after the last vaccination dose. RESULTS: A total of 522 patients were included, mainly men who have sex with men (86.2%). In the standard-dose group, 303/343 [88.3%; 95% confidence interval (CI): 84.5 to 91.5] patients showed seroconversion as compared with 149/179 (83.2%; 95% CI: 76.9 to 88.4) of the single-dose group (P = 0.107). Undetectable baseline HIV-RNA (adjusted odds ratio: 4.86; 95% CI: 1.86 to 12.75; P = 0.001) and a CD4 T-cell count ≥350/µL (adjusted odds ratio, 3.96; 95% CI: 1.26 to 12.49; P = 0.019) were independently associated with response to both regimens. A higher CD4/CD8 ratio was also associated with response after a single dose. CONCLUSIONS: HIV-infected patients should be encouraged to undergo HAV-V with 2 standard doses 6 months apart; a single dose achieves a high rate of seroconversion in those patients with favorable response factors and may be enough to limit future outbreaks in case of HAV-V shortage until supply is reestablished.

Low performance of ultrasound surveillance for the diagnosis of hepatocellular carcinoma in HIV-infected patients.

OBJECTIVE: To assess the performance of ultrasound surveillance for the diagnosis of hepatocellular carcinoma (HCC) in HIV-infected patients. METHODS: The GEHEP-002 cohort recruits HCC cases diagnosed in HIV-infected patients from 32 centers across Spain. The proportion of 'ultrasound lack of detection', defined as HCC diagnosed within the first 3 months after a normal surveillance ultrasound, and the proportion of 'surveillance failure', defined as cases in which surveillance failed to detect HCC at early stage, were assessed. To assess the impact of HIV, a control population of 104 HCC cases diagnosed in hepatitis C virus-monoinfected patients during the study period was used. RESULTS: A total of 186 (54%) out of 346 HCC cases in HIV-infected patients were diagnosed within an ultrasound surveillance program. Ultrasound lack of detection occurred in 16 (8.6%) of them. Ultrasound surveillance failure occurred in 107 (57%) out of 186 cases diagnosed by screening, whereas this occurred in 18 (29%) out of 62 diagnosed in the control group (P < 0.0001). HCC cases after ultrasound surveillance failure showed a lower frequency of undetectable HIV viral load at diagnosis. The probability of 1-year and 2-year survival after HCC diagnosis among those diagnosed by screening was 56 and 45% in HIV-infected patients, whereas it was 79 and 64% in HIV-negative patients (P = 0.038). CONCLUSION: The performance of ultrasound surveillance of HCC in HIV-infected patients is very poor and worse than that shown outside HIV infection. A HCC surveillance policy based on ultrasound examinations every 6 months might be insufficient in HIV-infected patients with cirrhosis.

Hepatocellular carcinoma after sustained virological response with interferon-free regimens in HIV/hepatitis C virus-coinfected patients.

OBJECTIVE: To assess the possible association between the use of direct antiviral agents (DAA) and the risk of hepatocellular carcinoma (HCC) in HIV/hepatitis C virus (HCV)-coinfected patients. METHODS: The GEHEP-002 cohort recruits HCC cases in HIV-infected patients from 32 centers from Spain. Three analyses were performed: the proportion of HCC cases after sustained virological response (SVR) and the evolution of this proportion over time, the frequency of HCC after SVR in HIV/HCV-coinfected patients with cirrhosis, and the probability of HCC recurrence after curative therapies among those undergoing HCV therapy. RESULTS: Forty-two (13%) out of 322 HCC cases in HIV/HCV-coinfected patients occurred after SVR. Twenty-eight (10%) out of 279 HCC cases diagnosed during the years of use of IFN-based regimens occurred after SVR whereas this occurred in 14 (32.6%) out of the 43 HCC cases diagnosed in the all-oral DAA period (P < 0.0001). One thousand, three hundred and thirty-seven HIV/HCV-coinfected patients with cirrhosis achieved SVR in the cohort. The frequency of HCC after SVR declined from 15% among those cured with pegylated-IFN with ribavirin to 1.62 and 0.87% among those cured with DAA with and without IFN, respectively. In patients with previous HCC treated with curative therapies, HCC recurrence occurred in two (25%) out of eight patients treated with IFN-based regimens and four (21%) out of 19 treated with DAA-IFN-free regimens (P = 1.0). CONCLUSION: The frequency of HCC emergence after SVR has not increased after widespread use of DAA in HIV/HCV-coinfected patients. DAA do not seem to impact on HCC recurrence in the short-term among those with previously treated HCC.

Real-life experience with sorafenib for the treatment of hepatocellular carcinoma in HIV-infected patients.

OBJECTIVE: To report the real-life results of sorafenib use in a cohort of HIV-infected patients with hepatocellular carcinoma (HCC). METHODS: The GEHEP-002 cohort (ClinicalTrials.gov ID: NCT02785835) has recruited 302 HCC cases diagnosed in HIV-infected patients from 32 centers from Spain. RIS-HEP12 study included 44 (14%) cases that have received at least one dose of sorafenib. The overall survival after the start of treatment was the main efficacy outcome. Permanent discontinuation due to adverse events was the primary safety end point. RESULTS: Reasons for sorafenib use are HCC recurrence after previous curative therapy (n = 7), progression following transarterial chemoembolization (n = 6) and first treatment against HCC (n = 31). Nineteen (43%) patients harbored Child-Pugh B cirrhosis. Barcelona-Clinic Liver Cancer stage was A 3 (7%), B 6 (14%), C 30 (68%) and D 5 (11%). All patients were on antiretroviral therapy (ART). The median (Q1-Q3) duration of sorafenib treatment was 70 (31-158) days. Median survival was 7.2 months, whereas the median (Q1-Q3) duration of overall survival after the start of treatment was 4 (2-9.7) months. Twenty-six (59%) patients had any grade adverse events and 19 (43%) suffered a decompensation. Discontinuation due to adverse events occurred in 17 (38.6%) patients. There were no modifications or discontinuations of ART. CD4 cell counts and HIV viral load remained stable. CONCLUSION: The efficacy of sorafenib under real-life conditions in HIV-infected patients seems lower than that reported in the registration clinical trial. On the contrary, the tolerability of sorafenib appears to be similar to what is seen in patients without HIV infection. Sorafenib does not seem to modify the efficacy of ART.

No evidence of firstly acquired acute hepatitis C virus infection outbreak among HIV-infected patients from Southern Spain: a multicentric retrospective study from 2000-2014.

BACKGROUND: Acute hepatitis C virus (HCV) infection (AHCVI) outbreaks have been described recently within defined areas worldwide among HIV-infected homosexual men. This study aims to describe the cumulative frequency and incidence of firstly acquired AHCVI in an HIV-infected population in Southern Spain. METHODS: This is a retrospective study conducted at the Infectious Diseases Units of eight hospitals in Andalusia, Southern Spain. Primary AHC was considered as HCV immunoglobulin G antibody seroconversion. The time of infection was considered the moment between the last negative and the first positive HCV antibody determination. RESULTS: A total of 23 cases of primary AHCVI have been detected from 2000 to 2014. Incidence rates [IR; 95 % confidence interval (CI)] were 0.036 (2.272-0.054) per 100 person-years (py) in the overall population over a follow-up period of 64170 py. Of the 22 (95.7 %) male subjects, 21 (95.5 %) had acquired AHCVI by homosexual contact, the IR (95 % CI) was 0.039 (0.024-0.06) per 100 py in this subpopulation. There was no evidence of an increase of AHCVI IR. The incidence of AHCVI was slightly lower between 2000 and 2004 as compared to 2005-2009 [IR ratio (IRR) of 8.8 (95 % CI: 1.279-378.794; p = 0.01)] but reached a plateau afterwards [IRR between 2010 and 2014 versus 2005-2009: 0.727 (0.286-1.848; p = 0.5)]. The median (Q1-Q3) time between the last negative anti-HCV and the first positive anti-HCV determination was 4.7 (1.9-11.2) months. Peak (Q1-Q3) ALT and total bilirubin values during AHCVI were 496 (291-656) IU/mL and 1.15 (0.9-1.98) mg/dL, respectively. CONCLUSIONS: In contrast to what has been reported from other areas, the incidence of primary AHCVI in the HIV-infected population is stable in Southern Spain and there is no evidence of an epidemic, in spite of the high prevalence of HIV/HCV-coinfection in this area.

Hepatic Safety of Rilpivirine/Emtricitabine/Tenofovir Disoproxil Fumarate Fixed-Dose Single-Tablet Regimen in HIV-Infected Patients with Active Hepatitis C Virus Infection: The hEPAtic Study.

OBJECTIVES: The aim of this study was to evaluate the frequency of transaminase elevations (TE) and total bilirubin elevations (TBE) during the first year of therapy with a single tablet regimen including RPV/FTC/TDF (EPA) in HIV/hepatitis C virus (HCV)-coinfected subjects in clinical practice. METHODS: In a retrospective analysis, HIV/HCV-coinfected subjects who started EPA at 17 centres throughout Spain were included as cases. Subjects who started an antiretroviral therapy (ART) other than EPA during the study period at the same hospitals were randomly selected as controls in a 1:2 ratio. Primary outcome variables were grade (G) 3-4 TE and G4 TBE. RESULTS: Of the 519 subjects included, 173 individuals started EPA. Nine (5.2%) subjects of the EPA group and 49 (14.2%) controls were naïve to ART. The median (Q1-Q3) follow-up was 11.2 (9.7-13.9) months. TE was observed in 2 [1.2%; 95% confidence interval (CI): 0.14%-4.1%] subjects receiving EPA and 11 (3.2%; 95%CI: 1.6%-5.6%) controls (p = 0.136), all events were G3. No patient discontinued ART due to TE. One (0.6%; 95%CI: 0.01%-3.1%) subject on EPA and 8 (2.3%; 95%CI: 1%-4.5%) subjects in the control group developed TBE (p = 0.141), without developing any other hepatic event during follow-up. Three (2.3%) subjects with cirrhosis versus 10 (3.1%) without cirrhosis showed G3-4 TE (p = 0.451). CONCLUSION: The frequency of severe liver toxicity in HIV/HCV-coinfected subjects receiving EPA under real-life conditions is very low, TE were generally mild and did not lead to drug discontinuation. All these data suggest that EPA can be safely used in this particular subpopulation.

Hepatic safety of RPV/FTC/TDF single tablet regimen in HIV/HCV-coinfected patients. Preliminary results of the hEPAtic Study.

INTRODUCTION: Although hepatotoxicity related to antiretroviral treatment (ART) has become less frequent, hepatotoxic events, such as transaminase elevations (TE), are still a matter of concern. RPV/FTC/TDF (EPA) is a new single tablet regimen which is widely used in real life practice. Clinical trials showed an adequate profile of liver safety in the sub-population of HIV/HCV-coinfected patients receiving rilpivirine. However, the number of individuals included in these analyses is low (1). The aim of this ongoing study is to evaluate the incidence of TE and total bilirubin elevations (TBE) during the first 48 weeks of EPA-based therapy in a large population of HIV/HCV-coinfected subjects outside of clinical trials. PATIENTS AND METHODS: This is a retrospective analysis of HIV/HCV-coinfected subjects who started EPA at the infectious diseases units of 14 centres throughout Spain, included as cases. Subjects who started an ART different to EPA during the study period at the same hospitals were selected as controls. The primary outcome variables were grade 3 or 4 TE and grade 4 TBE. RESULTS: Of the 191 patients included, 31 (16.2%) subjects were naïve to ART. Eighty-seven individuals started EPA and the remaining ones were controls. The most common NRTI backbone among the controls was TDF/FTC [59 (56.7%) patients] followed by NRTI-sparing regimens [24 (23.1%) individuals] and ABC/3TC [17 (16.3%) subjects]. Among controls, 67 (64.4%) started a ritonavir-boosted protease inhibitor, mainly DRV/r [41 (39.4%) patients] followed by ATV/r [16 (15.4%) subjects]. EFV, ETV and RAL were started in 16 (15.4%), 12 (11.5%) and 13 (12.5%) subjects, respectively. The median (Q1-Q3) follow-up was 5.79 (3.65-8.61) months for the cases and 11.44 (5.8-12.88) months for the controls. TE was observed in two (2.3%) cases versus five (4.8%) controls (p=0.358), accounting for a density of incidence of 4.32/100 person-years versus 5.51/100 person-years [incidence rate difference (95% confidence interval): -1.88 (-9.95-6.2), p=0.354]. All TE were grade 3 and no patient discontinued ART due to TE. None of the cases developed TBE versus four (3.8%) controls, all of them receiving ATV/r. CONCLUSIONS: The frequency of grade 3-4 TE associated with EPA in HIV/HCV-coinfected patients under real life conditions is very low. In addition, TE in HIV/HCV-coinfected patients treated with EPA are usually mild and do not lead to treatment discontinuation. TBE was not seen in patients taking EPA. All these data confirm that EPA is safe in this particular subpopulation.

Clinical and virological efficacy of etravirine plus two active Nucleos(t)ide analogs in an heterogeneous HIV-infected population.

UNLABELLED: Etravirine (ETV) is recommended in combination with a boosted protease inhibitor plus an optimized background regimen for salvage therapy, but there is limited experience with its use in combination with two nucleos(t)ide reverse-transcriptase inhibitors (NRTIs). This multicenter study aimed to assess the efficacy of this combination in two scenarios: group A) subjects without virologic failure on or no experience with non-nucleoside reverse-transcriptase inhibitors (NNRTIs) switched due to adverse events and group B) subjects switched after a virologic failure on an efavirenz- or nevirapine-based regimen. The primary endpoint was efficacy at 52 weeks analysed by intention-to-treat. Virologic failure was defined as the inability to suppress plasma HIV-RNA to <50 copies/mL after 24 weeks on treatment, or a confirmed viral load >200 copies/mL in patients who had previously achieved a viral suppression or had an undetectable viral load at inclusion. Two hundred eighty seven patients were included. Treatment efficacy rates in group A and B were 88.0% (CI95, 83.9-92.1%) and 77.4% (CI95, 65.0-89.7%), respectively; the rates reached 97.2% (CI95, 95.1-99.3%) and 90.5% (CI95, 81.7-99.3), by on-treatment analysis. The once-a-day ETV treatment was as effective as the twice daily dosing regimen. Grade 1-2 adverse events were observed motivating a treatment switch in 4.2% of the subjects. In conclusion, ETV (once- or twice daily) plus two analogs is a suitable, well-tolerated combination both as a switching strategy and after failure with first generation NNRTIs, ensuring full drug activity. TRIAL REGISTRATION: ClinicalTrials.gov NCT01437241.

HIV/hepatitis C virus-coinfected patients who achieved sustained virological response are still at risk of developing hepatocellular carcinoma.

OBJECTIVE: To describe the frequency and the characteristics of hepatocellular carcinoma (HCC) cases that appeared in HIV/hepatitis C virus (HCV)-coinfected patients with previous sustained virological response (SVR) and to compare these cases to those diagnosed in patients without SVR. METHODS: All HIV/HCV-coinfected patients diagnosed with HCC in 26 hospitals in Spain before 31 December 2012 were analyzed. Comparisons between cases diagnosed in patients with and without previous SVR were made. RESULTS: One hundred and sixty-seven HIV/HCV-coinfected patients were diagnosed with HCC in the participant hospitals. Sixty-five (39%) of them had been previously treated against HCV. In 13 cases, HCC was diagnosed after achieving consecution of SVR, accounting for 7.8% of the overall cases. The median (Q1-Q3) elapsed time from SVR to diagnosis of HCC was 28 (20-39) months. HCC was multicentric and was complicated with portal thrombosis in nine and six patients, respectively. Comparisons with HCC cases diagnosed in patients without previous SVR only yielded a significantly higher proportion of genotype 3 infection [10 (83%) out of 13 cases versus 34 (32%) out of 107; P = 0.001)]. The median (Q1-Q3) survival of HCC was 3 (1-39) months among cases developed in patients with previous SVR, whereas it was 6 (2-20) months in the remaining individuals (P = 0.7). CONCLUSION: HIV/HCV-coinfected patients with previous SVR may develop HCC in the mid term and long term. These cases account for a significant proportion of the total cases of HCC in this setting. Our findings reinforce the need to continue surveillance of HCC with ultrasound examinations in patients with cirrhosis who respond to anti-HCV therapy.

Increasing incidence of hepatocellular carcinoma in HIV-infected patients in Spain.

BACKGROUND: To report the clinical and epidemiological characteristics of hepatocellular carcinoma (HCC) diagnosed in a cohort of human immunodeficiency virus (HIV)-infected patients in Spain. METHODS: All HIV-infected patients diagnosed of HCC in 18 hospitals in Spain before 31 December 2010 were included. The main characteristics of HCC cases are described and comparisons between cases according to the year of diagnosis are presented. RESULTS: Eighty-two cases of HCC in HIV-infected patients were included, all of them related to viral hepatitis coinfection: hepatitis C virus (HCV) in 66 (81%), hepatitis B virus (HBV) in 6 (7%), and HBV/HCV in 10 (12%). From 1999, when the first case of HCC was diagnosed, a progressive increment in the incidence of HCC in the cohort has occurred. In patients coinfected with HIV/HCV-coinfected patients, the incidence HCC increased from 0.2 to 2.8 cases per 1000 person-years between 2000 and 2009. Death occurred in 65 patients (79%), with a median survival of 91 days (interquartile range, 31-227 days). Three of 11 patients (28%) who received potentially curative therapy died, compared with 62 of 71 patients (87%) who did not receive curative therapy (P = .0001). Compared with cases of HCC diagnosed before 2005, cases diagnosed later did not show a higher survival rate. CONCLUSIONS: HCC is an emerging complication of cirrhosis in HIV-infected patients. A sharp increase in its incidence has occurred in those also infected by HCV in the recent years. Unfortunately, HCC is frequently diagnosed at an advanced stage, and mortality continues to be very high, with no significant changes in recent years. Earlier diagnosis, which may allow potentially curative therapy, is necessary.

Liver toxicity of antiretroviral combinations including fosamprenavir plus ritonavir 1400/100 mg once daily in HIV/hepatitis C virus-coinfected patients.

Abstract Our objective was to evaluate the liver toxicity of antiretroviral regimens including fosamprenavir plus ritonavir (FPV/r) 1400/100 mg once daily (QD) in HIV/hepatitis C virus (HCV)-coinfected patients. This was a prospective cohort study that included 117 HIV/HCV-coinfected patients who started FPV/r 1400/100 mg QD-based antiretroviral therapy (ART) and who neither had received a previous antiretroviral regimen containing FPV nor had a past history of virologic failure while receiving protease inhibitors (PI). The primary end point of the study was the occurrence of grade 3-4 liver enzymes elevations (LEE) within 1 year after starting FPV/r QD. Factors potentially associated with grade 3-4 LEE, including baseline liver fibrosis, were analyzed. Eleven (9%) patients had a grade 3-4 LEE during the follow-up, resulting in an incidence of severe liver toxicity of 9% (95% confidence interval 4.1-14.6%). None of these cases led to FPV/r discontinuation. Baseline liver fibrosis could be assessed in 97 (83%) patients. Six of 71 patients (8%) with significant fibrosis had a grade 3-4 LEE versus 2 of 26 (8%) without significant fibrosis (p=1.0). Twenty (21%) patients had cirrhosis at baseline. There were no cases of LEE among cirrhotics. In conclusion, the incidence of severe liver toxicity after 1 year of therapy with FPV/r QD-based ART in HIV/HCV-coinfected patients is similar to what has been reported with other boosted PIs. In addition, the presence of significant fibrosis or cirrhosis was not associated with the emergence of liver toxicity. Thus, ART regimens containing FPV/r QD may be considered safe in HIV/HCV-coinfected patients, including those with cirrhosis.
