Background Drug–drug interactions between antiretroviral treatment (ART) and cytostatics may have a negative impact in the prognosis of people with HIV (PWH) and cancer. Objective The objective of this study is to evaluate the impact of the implementation of interdisciplinary management and the type of ART in PWH diagnosed with lymphoid neoplasms. Methods This is a multicentric, retrospective observational cohort study including PWH diagnosed with lymphoid neoplasm who started first-line chemotherapy between 2008 and 2020. Demographic, clinical and therapeutic variables were obtained from the electronic medical records and associated with 5-year progression-free survival (PFS) and overall survival (OS) using Cox proportional hazard models. Results A total of 118 individuals were included. Boosted ART was being used in 55 (46.6%) cases at the time of neoplasm diagnosis. The Infectious Diseases or the Pharmacy Department was consulted before starting chemotherapy in 79/118 (66.9%) cases. Interdisciplinary management resulted in fewer subjects taking boosted ART (17.7% versus 71.8%, P  < 0.001) and more subjects using unboosted integrase strand transfer inhibitor–based ART (74.7% versus 7.7%, P  < 0.001). The use of boosted ART with chemotherapy was associated with worse 5-year PFS (P  = 0.003) and 5-year OS (P  = 0.016). There was a trend towards better 5-year PFS and OS when interdisciplinary management was implemented, with significant differences for individuals receiving boosted ART at neoplasm diagnosis (P  = 0.0246 and P  = 0.0329, respectively). Conclusions Our findings underscore the significant impact of the type of ART on the prognosis of PWH undergoing chemotherapy. Encouraging collaborative management between oncologists, pharmacists and HIV teams for these patients enhances PFS and OS rates. [ABSTRACT FROM AUTHOR]

Objectives To describe the management of haematological patients experiencing prolonged SARS-CoV-2 viral shedding, as the optimal management strategy for this condition remains undetermined. Methods We conducted a retrospective evaluation of our prospectively followed cohort of haematological patients treated with remdesivir for more than 10 days. Starting January 2023, upon COVID-19 diagnosis, the treatment strategy was based on symptoms and PCR cycle threshold (Ct) as follows: (i) when Ct was 25 or less or if the patient had symptoms, a course of remdesivir for at least 10 days, nirmatrelvir/ritonavir for 5 days (whenever possible) and convalescent plasma was administered; and (ii) when the patient was asymptomatic and had a PCR Ct of more than 25, when possible, a course of 5 days of nirmatrelvir/ritonavir was administered. The patient was considered to have achieved viral clearance and, thus, remdesivir was stopped, in either of these cases: (i) PCR negativity, or (ii) subgenomic RNA negativity. Results From January to November 2023, 18 patients benefited from a safe extended remdesivir administration, resulting in detection of SARS-CoV-2 viral clearance in a median time of 3.5 weeks (IQR 2.6–3.9) (min–max 1.6–8.0). No clinical or biological side effects were detected. No patient died or needed further treatment for their COVID-19 episode. Conclusions The extended course of remdesivir, combined with other active therapies for COVID-19 infection, was well tolerated. Cure and virus negativity were obtained in all these high-risk patients. [ABSTRACT FROM AUTHOR]

Background: Immunoglobulin (IG) therapy is widely used to treat primary and secondary immune deficiencies and as immunomodulatory agent for various disorders. There is great concern that shortages of IG may rise, potentially affecting medical treatment options. Study Design and Methods: An international survey was developed to study how intravenous immunoglobulins (IVIGs) are used and managed within hospitals in case of shortages. Study data were collected and managed using REDCap electronic data capture tools hosted by the Biomedical Excellence for Safer Transfusion (BEST) Collaborative. The survey was directed to hospital pharmacists and blood bank transfusion professionals and disseminated through members of the BEST Collaborative network. Results: Survey respondents from institutions in the USA, Canada, Europe, Japan, and Australia (n = 13) confirmed that the primary specialties utilizing IG are neurology, hematology, and immunology. More than 60% of respondents reported IG supply shortages, but mitigation strategies were not well developed. Discussion: As IG is the leading driver in plasma demand, more studies are needed to understand current and future demand for IG from the clinical perspective. Necessity lies in establishing clinical guidance to address shortages. [ABSTRACT FROM AUTHOR]

Background. Antimicrobial resistance killed 1.27 million people in 2019, so urgent actions are desperately needed. Antimicrobial stewardship programmes (ASPs) are essential to optimize antimicrobial use. The objective was to acknowledge the current role of clinical pharmacists engaged in ASP activities in Catalonia. Methods. This was a cross-sectional survey shared through the Catalan Infection Control Programme (VINCat). The survey consisted of four sections and was sent by e-mail. Results. A total of 69.0% of the centres answered. Pharmacists dedicated a median of 5.0 h per week (2.1 h/week/100 acute care beds), representing 0.15 full time equivalents. The ASP lacked information technology (IT) support, as only 16.3% of centres automatically calculated defined daily doses and days of therapy. Those with less than 15% of their time available for ASPs conducted fewer clinical activities, especially prospective audits and feedback. Those without official infectious diseases training also performed fewer clinical activities, but training was less determinant than IT support or time. Pharmacists performed interventions mostly through annotation in the medical records. Conclusions. Clinical pharmacists from Catalonia dedicated to ASPs present an important lack of time and IT support to perform clinical activities. Pharmacists should also improve their clinical skills and try to conduct clinical advice to prescribers, either by phone or face-to-face. [ABSTRACT FROM AUTHOR]

Background There is no reliable microbiological marker to guide the indication and the response to antiviral treatment in patients with coronavirus disease 2019 (COVID-19). We aimed to evaluate the dynamics of subgenomic RNA (sgRNA) in patients with COVID-19 before and after receiving treatment with remdesivir. Methods We included consecutive patients admitted for COVID-19 who received remdesivir according to our institutional protocol and accepted to participate in the study. A nasopharyngeal swab for quantitative reverse transcriptase–polymerase chain reaction (qRT-PCR) was collected at baseline and after 3 and 5 days of treatment with remdesivir. Genomic and sgRNA were analyzed in those samples and main comorbidities and evolution were collected for the analyses. The main outcomes were early discharge (≤10 days) and 30-day mortality. Results A total of 117 patients were included in the study, of whom 24 had a negative sgRNA at baseline, with 62.5% (15/24) receiving early discharge (≤10 days) and no deaths in this group. From the 93 remaining patients, 62 had a negative sgRNA at day 5 with 37/62 (59.6%) with early discharge and a mortality rate of 4.8% (3/62). In the subgroup of 31 patients with positive sgRNA after 5 days of remdesivir, the early discharge rate was 29% (9/31) and the mortality rate was 16.1% (5/31). In multivariable analyses, the variables associated with early discharge were negative sgRNA at day 3 and not needing treatment with corticosteroids or intensive care unit admission. Conclusions Qualitative sgRNA could help in monitoring the virological response in patients who receive remdesivir. Further studies are needed to confirm these findings. [ABSTRACT FROM AUTHOR]

Giving HIV patients indinavir along with ritonavir may allow them to take both protease inhibitors once a day rather than two or three times a day. This is possible because ritonavir reduces the metabolism of indinavir, making it last longer in the body.

Background: The use of remdesivir has demonstrated a significant reduction in the time to recovery in patients with COVID-19. However, the impact on mortality is still controversial. Therefore, it is necessary to evaluate whether there is a specific subgroup of patients in whom an active antiviral therapy also reduces the mortality., Methods: Patients admitted for >48 h in our hospital for a SARS-CoV-2 confirmed or suspected infection from February 2020 to February 2021 were retrospectively analysed. The primary outcome of the study was mortality at 30 days. Univariate and multivariate analyses were performed to identify predictors of mortality., Results: In total, 2607 patients (438 receiving remdesivir and 2169 not) were included with a median (IQR) age of 65 (54-77) years and 58% were male. Four hundred and seventy-six were admitted to the ICU (18.3%) and 264 required invasive mechanical ventilation (10.1%). The global 30 day mortality rate was 10.7%. Pre-admission symptom duration of 4-6 days and ≤3 days was associated with a 1.5- and 2.5-fold increase in the mortality rate, respectively, in comparison with >6 days and treatment with remdesivir was independently associated with a lower mortality rate (OR = 0.382, 95% CI = 0.218-0.671). The analysis showed that the major difference was among patients with shorter pre-admission symptom duration (<6 days)., Conclusions: Patients with ≤3 days and 4-6 days from symptom onset to admission are associated with a 2.5- and 1.5-fold higher risk of death, respectively. Remdesivir was associated with 62% reduced odds of death versus standard-of-care and its survival benefit increased with shorter duration of symptoms., (© The Author(s) 2021.

Purpose: In recent decades, the life expectancy of HIV-infected patients has increased considerably, to the extent that the disease can now be considered chronic. In this context of progressive aging, HIV-infected persons have a greater prevalence of comorbid conditions. Consequently, they usually take more non-antiretroviral drugs, and their drug therapy are more complex. This supposes a greater risk of drug interactions, of hospitalization, falls, and death. In the last years, deprescribing has gained attention as a means to rationalize medication use., Methods: Review of the different therapeutic approach that includes optimization of polypharmacy and control and reduction of potentially inappropriate prescription., Results: There are several protocols for systematizing the deprescribing process. The most widely used tool is the Medication Regimen Complexity Index, an index validated in HIV-infected persons. Anticholinergic medications are the agents that have been most associated with major adverse effects so, various scales have been employed to measure it. Other tools should be employed to detect and prevent the use of potentially inappropriate drugs. Prioritization of candidates should be based, among others, on drugs that should always be avoided and drugs with no justified indication., Conclusions: The deprescribing process shared by professionals and patients definitively would improve management of treatment in this population. Because polypharmacy in HIV-infected patients show that a considerable percentage of patients could be candidates for deprescribing, we must understand the importance of deprescribing and that HIV-infected persons should be a priority group. This process would be highly feasible and effective in HIV-infected persons.

Background and Objective: Different combinations of antiretroviral drugs are used as initial HIV therapy but comparative studies between them are not frequent. The objectives of this study are to determine the median duration of different therapy combinations in naive patients between 1998-2000 and the main reasons for changing or stopping this first antiretroviral therapy (ARVT)., Patients and Method: This study included a total of 518 naive patients who began antiretroviral therapy patients from 1998-2000. Using a Kaplan-Meier analysis the median duration of different combinations was determined. In addition, the main reasons for changing or stopping this first treatment were analysed., Results: First ARVT median duration was 427 days (IQR: 114-890). 47% of patients stopped their first therapy due to adverse effects, 6% voluntarily withdrew from it, in 9% of patients the therapy was not effective and 15% of them were lost of follow up. Only 9% of them continued with the same ARVT at the end of the study but if we add 7% of treatment simplifications we can consider 16% of first ARVT successful., Conclusions: A median duration of 427 days, similar to other studies, is shorter than we would prefer for HIV, a condition that requires continuous treatment. On the other hand, the study corroborates that secondary effects are the principal problem associated with ARVT.

According to current estimates, there are 60,000 to 80,000 HIV and HCV coinfected individuals in Spain, and 5,000 to 10,000 HIV and HBV coinfected individuals. Among these patients, 10% to 15% have liver cirrhosis. Thus, end-stage liver disease is one of the major causes of death in our country. Liver transplantation is the only therapeutic option for these patients. Accumulated experience in North America and Europe in the last five years indicates that three-year survival in HIV-positive liver transplant recipients is similar to that of HIV-negative recipients. The selection criteria for HIV transplant candidates includes the following: no history of opportunistic infections, CD4 lymphocyte count higher than 100 cells/mm3, and HIV viral load suppressible with antiretroviral treatment. In Spain, where the majority of patients are former drug abusers, complete abstinence from heroin or cocaine use during two years is also required, with the possibility of the patient being in a methadone program. To date 26 hepatic transplants have been performed in the same number of patients, with only two deaths (7%) after a median follow-up of eight months (1-28). The main problems in the post-transplantation period in all the series has been recurrent HCV infection, which is the principle cause of post-transplantation mortality, and pharmacokinetic and pharmacodynamic interactions between the antiretroviral and immunosuppressive agents. There is little experience with pegylated interferon and ribavirin treatment in this population.

This article summarizes the principal characteristics of the drugs used to treat viral infections, with the exception of human immunodeficiency virus infection. It includes antiviral agents active against herpes virus, cytomegalovirus, hepatitis B and C virus, and respiratory viruses, such as influenza and respiratory syncytial virus. Dosage according to the indication, dose adjustment in the case of renal or hepatic insufficiency, significant pharmacokinetic characteristics, and the main adverse effects and interactions are described.
