Benefits of rilpivirine for liver stiffness in HIV/HCV-coinfected patients.

BACKGROUND: Rilpivirine (RPV) is an antiretroviral drug characterized by good tolerability and a favorable liver safety profile. Recent research has shown that RPV ameliorates liver fibrosis in animal models of various chronic liver diseases. Our study aimed to analyze the effect of RPV on liver fibrosis by assessing changes in liver stiffness using transient elastography. METHODS: Retrospective cohort study of HIV-infected patients who were exposed and not exposed to RPV. The change in liver stiffness during the period between two transient elastography measurements was analyzed and compared for patients exposed and not exposed to RPV. RESULTS: We selected 118 RPV-exposed and 118 non-RPV-exposed HIV-infected patients. Median time between transient elastography (TE) measurements was 50 (29-68) months. A repeated-measures general linear model based on the main clinical characteristics revealed a significant decrease in the TE value of -0.8kPa in non-RPV-exposed patients (p=0.254) and -1.6kPa in the RPV-exposed group (p<0.001). The subgroup analysis showed a significant reduction in the TE value only patients cured of hepatitis C (RPV-exposed, -2.8kPa [p<0.001]; non-RPV-exposed, -1.1kPa [p=0.22]). CONCLUSION: RPV-based antiretroviral regimens significantly reduced liver stiffness, as measured by TE, in patients cured of chronic hepatitis C.

Antecedentes: La rilpivirina (RPV) es un fármaco antirretroviral caracterizado por una buena tolerabilidad y un perfil de seguridad hepática favorable. Las últimas investigaciones han mostrado que la RPV mejora la fibrosis hepática en modelos animales de varias enfermedades hepáticas crónicas. Nuestro estudio tenía como objetivo analizar el efecto de la RPV en la fibrosis hepática mediante la evaluación de cambios en la rigidez hepática utilizando una elastografía transitoria. Métodos: Estudio de cohortes retrospectivo de pacientes infectados por VIH expuestos y no expuestos a RPV. Se analizó el cambio en la rigidez hepática durante el período entre dos mediciones mediante elastografía transitoria y se comparó entre pacientes expuestos y no expuestos a RPV. Resultados: Seleccionamos a 118 pacientes infectados por VIH expuestos a RPV y 118 pacientes infectados por VIH no expuestos a RPV. La mediana del tiempo entre las mediciones mediante elastografía transitoria (ET) fue de 50 (29-68) meses. Un modelo lineal general de medidas repetidas basado en las principales características clínicas reveló una reducción significativa en el valor de ET, −0,8kPa en el grupo de pacientes no expuestos a RPV (p=0,254) y de −1,6kPa en el grupo de pacientes expuestos a RPV (p<0,001). El análisis de subgrupos mostró una reducción significativa en el valor de ET solo en pacientes curados de hepatitis C (expuestos a RPV, −2,8kPa [p<0,001]; no expuestos a RPV, −1,1kPa [p=0,22]). Conclusión: Las pautas antirretrovirales basadas en RPV redujeron significativamente la rigidez hepática, evaluada por las mediciones de ET, en los pacientes que se habían curado de hepatitis C crónica.(AU)

Efficacy, Safety, and Durability of Long-Acting Cabotegravir and Rilpivirine in Adults With Human Immunodeficiency Virus Type 1 Infection: 5-Year Results From the LATTE-2 Study.

BACKGROUND: In the Long-Acting Antiretroviral Treatment Enabling Trial 2 (LATTE-2) phase 2b study, long-acting (LA) injectable cabotegravir + rilpivirine dosed every 8 weeks (Q8W) or every 4 weeks (Q4W) demonstrated comparable efficacy with daily oral antiretroviral therapy (ART) through 96 weeks in ART-naive adults with human immunodeficiency virus type 1 (HIV-1). Here we report efficacy, tolerability, and safety of cabotegravir + rilpivirine LA over approximately 5 years. METHODS: After 20 weeks of oral cabotegravir + abacavir/lamivudine, participants were randomized to cabotegravir + rilpivirine LA Q8W or Q4W or continue oral ART through the 96-week maintenance period. In the extension period through week 256, participants continued their current LA regimen (randomized Q8W/Q4W groups) or switched from oral ART to Q8W or Q4W LA therapy (extension-switch groups). Endpoints assessed included proportion of participants with HIV-1 RNA <50 copies/mL (Snapshot algorithm) and adverse events (AEs). RESULTS: At week 256, 186 of 230 (81%) participants in randomized Q8W/Q4W groups and 41 of 44 (93%) participants in extension-switch groups had HIV-1 RNA <50 copies/mL. No protocol-defined virologic failures occurred after week 48. Injection wsite reactions infrequently resulted in discontinuation (4 [2%] and 1 [2%] participants in randomized Q8W/Q4W and extension-switch groups, respectively). Three participants in randomized Q8W/Q4W groups experienced drug-related serious AEs, including 1 fatal serious AE (Q4W group); none occurred in extension-switch groups. Of 25 participants with AEs leading to withdrawal, 20 were in the randomized Q4W group; no AE leading to withdrawal occurred in >1 participant. CONCLUSIONS: Cabotegravir + rilpivirine LA exhibited long-term efficacy and tolerability, demonstrating its durability as maintenance therapy for HIV-1 infection.Clinical Trials Registration.

Psoriasis and Liver Damage in HIV-Infected Patients.

Background/objectives: Psoriasis is the most frequent skin disease in HIV-infected patients. Nonalcohol fatty liver disease (NAFLD) is more prevalent in patients with psoriasis. We report the prevalence of psoriasis and NAFLD and investigate risk factors of liver damage in HIV-infected patients with psoriasis. Methods: We performed a retrospective observational study. Steatosis was defined as indicative abdominal ultrasound findings, CAP (controlled attenuated parameter by transient elastography) > 238 dB/m, and/or triglyceride and glucose index (TyG) > 8.38. Significant (fibrosis ≥ 2) and advanced liver fibrosis (fibrosis ≤ F3) were studied by transient elastography (TE) and/or FIB-4 using standard cutoff points. FIB-4 (Fibrosis 4 score) results were adjusted for hepatitis C (HCV)-coinfected patients. Results: We identified 80 patients with psoriasis (prevalence, 1.5%; 95% CI, 1.1-1.8). Psoriasis was severe (PASI > 10 and/or psoriatic arthritis) in 27.5% of cases. The prevalence of steatosis was 72.5% (95% CI, 65-85). Severe psoriasis was an independent risk factor for steatosis (OR, 12; 95% CI, 1.2-120; p = 0.03). Significant liver fibrosis (p < 0.05) was associated with HCV coinfection (OR 3.4; 95% CI, 1.1-10.6), total CD4 (OR 0.99; 95% CI, 0.99-1), and time of efavirenz exposure (OR 1.2; 95% CI, 1.0-1.3). Conclusions: The prevalence of psoriasis in HIV-infected patients was similar to that of the general population. Steatosis is highly prevalent, and severe psoriasis is an independent risk factor for steatosis in HIV-infected patients.

Pacientes con hepatitis C perdidos en el sistema: aspectos éticos-legales y resultados de su búsqueda / No disponible

INTRODUCCIÓN: se conoce la existencia de pacientes con hepatitis C perdidos en el sistema, pero se desconocen su prevalencia y características. Además, su identificación colisiona con la barrera de la protección de datos. MÉTODOS: se presentó un protocolo de identificación y contacto al Comité de Ética Asistencial. Se obtendrían las serologías anti-VHC+ de Microbiología entre 2010-18. Se analizaría su situación en la base de datos hospitalaria y regional. Se clasificarían: a) hepatitis C crónica, si última determinación de ARN-VHC+; b) hepatitis C curada, si última determinación de ARN-VHC- tras 12 semanas de tratamiento; c) hepatitis C posible, si anti-VHC+ sin determinación de ARN-VHC. Se considerarían perdidos aquellos con hepatitis C crónica o posible sin seguimiento en Digestivo o Medicina Interna. Se contactaría con ellos mediante correo postal y, posteriormente, por teléfono para ofrecerles tratamiento. RESULTADOS: el Comité de Ética consideró que el protocolo cumplía los principios bioéticos de autonomía, beneficencia, no maleficencia y justicia, y que el contacto era éticamente deseable. Sobre 4.816 serologías anti-VHC+ identificamos 677 pacientes perdidos (14,06 %; IC 95 %: 13,2-15,2): edad 54 años, 61 % hombres, 12 % extranjeros y 95 % monoinfectados. Se consumieron 1,3 minutos en el estudio de cada serología. Un 25 % de las perdidas habían sido solicitadas por Digestivo o Medicina Interna. De los 677 perdidos, 228 (33,7 %) tenían también ARN-VHC+ y 449 (66,3 %) solo tenían solicitada la serología. CONCLUSIÓN: un número importante de pacientes con hepatitis C se encuentran perdidos en el sistema. Su búsqueda y contacto es posible desde el punto de vista ético-legal

Patients with hepatitis C lost to follow-up: ethical-legal aspects and search results.

INTRODUCTION: data on the prevalence and characteristics of hepatitis C patients lost to follow-up are lacking. In addition, the identification of this population clashes with data protection regulations. METHODS: the identification and contact protocol was submitted to the Health Care Ethics Committee. The protocol was based on anti-HCV serology test results for 2010-2018, which were obtained from the Microbiology Department. In addition, the situation of the patients in the hospital and regional database was analyzed, based on the following classification: a) chronic hepatitis C, if the last HCV RNA determination was positive; b) cured hepatitis C, if the last HCV RNA determination was negative after 12 weeks of treatment; and c) possible hepatitis C, if anti-HCV antibodies were positive with no result for HCV RNA. Lost patients were defined as those with chronic or possible hepatitis C and no follow-up in the Digestive Diseases or Internal Medicine Departments. The patients were contacted by postal mail and then by telephone, so that they could be offered treatment. RESULTS: the Ethics Committee considered that the protocol fulfilled the bioethical principles of autonomy, beneficence, non-maleficence and justice and that contact was ethically desirable. From 4,816 positive anti-HCV serology results, 677 patients were identified who were lost to follow-up (14.06 %; 95 % CI, 13.2-15.2). The mean age was 54 years, 61 % were male, 12 % were foreign born and 95 % were mono-infected. The study of each serology result took 1.3 minutes. One-quarter (25 %) of the losses corresponded to the Digestive Diseases and Internal Medicine Departments. Of the 677 losses, serology testing had only been ordered for 449 patients (66.3 %) and the remaining 228 (33.7 %) also had a positive HCV RNA result. CONCLUSION: a large number of patients with hepatitis C are lost to follow-up. Searching for and contacting these patients is legally and ethically viable.

IgG4-related disease in a patient with HIV infection.

A 47-year-old HIV-positive man with good immune and virological status presented with chronic multiple enlarged lymph nodes, lung disease and eosinophilia. Radiologic tests showed enlarged cervical, thoracic and axillary lymph nodes, with interstitial lung damage. After several non-specific histologic studies, an elevated serum IgG4 level led us to request immunohistochemistry of a lymph node sample. The test confirmed the diagnosis of IgG4-related disease.

Central nervous system penetration and effectiveness of darunavir/ritonavir monotherapy.

Darunavir/ritonavir monotherapy is an experimental switching strategy for virologically suppressed patients without protease inhibitor resistance to avoid nucleos(t)ide-related toxicities. This therapy maintains virological suppression in most patients, but at slightly lower rates than standard therapy that includes two nucleos(t)ides. Patients experiencing virological failure are generally re-suppressed without emergence of resistance with the resumption of two nucleos(t)ides. Reports of cerebrospinal fluid viral escape has been observed in patients receiving protease inhibitor monotherapy, and concerns exist regarding the capacity of protease inhibitor monotherapy to control HIV infection in the brain and to prevent neurocognitive decline. In the current report we have pooled together available evidence regarding the capacity of darunavir/ritonavir monotherapy to control HIV replication in cerebrospinal fluid and to prevent neurocognitive decline.

Incidence of hepatocellular carcinoma in HIV-infected patients with cirrhosis: a prospective study.

: This study assesses the incidence of hepatocellular carcinoma (HCC) in a prospective cohort of HIV-infected patients, the majority receiving antiretroviral therapy, with liver cirrhosis from different etiologies, enrolled between 2004 and 2005 with median follow-up of 5 years. We followed 371 patients, 25.6% with decompensated cirrhosis at baseline. The incidence rate of HCC was 6.72 per 1000 person-years [95% confidence interval (CI): 2.6 to 10.9]. There was a trend toward a higher cumulative probability of developing HCC at 6 years of follow-up (considering death and liver transplant as competing risks) in patients with decompensated versus compensated cirrhosis at baseline (6% vs. 2%, P < 0.06).

Tuberculosis complicating hepatitis C treatment in HIV-infected patients.

Tuberculosis characteristics and incidence were assessed among patients with concurrent human immunodeficiency virus infection and chronic hepatitis C virus infection who were receiving interferon-based therapy at 3 hospitals in Spain. Four of 570 patients (0.7 cases per 100 person-years; 95% confidence interval, 0.19-1.78 cases per 100 person-years) received a diagnosis of tuberculosis; all of them presented with a decrease in CD4+ cell count before diagnosis, and 3 of them received a delayed diagnosis. After tuberculosis treatment, all patients were cured.
