Efficacy and tolerability of dolutegravir/lamivudine versus dolutegravir/rilpivirine in switching from a three-drug regimen based on nonnucleoside reverse transcriptase inhibitors: A retrospective cohort study.

Real-life comparisons of dolutegravir/rilpivirine (DTG/RPV) and DTG/lamivudine (3TC) regimens in people living with human immunodeficiency virus (PLWHIV) who switched from a standard three-drug regimen based on nonnucleoside reverse transcriptase inhibitors (NNRTIs) are missing. This study aimed to compare DTG/3TC and DTG/RPV in virologically suppressed patients (HIV-RNA < 50 copies/mL) coming from any NNRTI-based regimen in terms of discontinuation due to virologic failure (VF) discontinuation rates due to all causes, and adverse events. As a secondary outcome, we evaluated the difference in creatinine, total cholesterol, CD4, and triglycerides from baseline to weeks 48 after the switch. Of the 415 PLWHs included in the study, 278 (66.9%) switched to DTG/3TC, and 137 (33.1%) switched to DTG/RPV. Overall, 48 PLWHs (11.6%) discontinued the treatment:38 with DTG/3TC and 10 with DTG/RPV with similar discontinuation rates: 5.01 × 100 py (95% confidence interval [CI] 3.64-6.94) and 4.66 × 100 py (95% CI 2.51-8.67), respectively. The most common reason for discontinuation was toxicity (26 patients, 22/278 [7.9%] in the DTG/3TC group and 4/137 [2.9%] in the DTG/RPV group), mainly neurologic toxicity (never above grade 2). We found no differences in discontinuation rates due to treatment adverse events. Two study participants experienced virological failure in the DTG/3TC arm. We observed no significant difference in CD4 cell counts, lipid parameters, or renal function between the two groups at 48 weeks. This study demonstrated that, in clinical practice, a two-drug regimen with DTG/3TC or DTG/RPV is characterized by a low discontinuation rate and VF in virologically suppressed PLWHs switched from an NNRTI-based three antiretroviral drugs regimen.

Hemophagocytic Lymphohistiocytosis and Miliary Tuberculosis in an Apparently Immunocompetent Patient: A Case Report.

Hemophagocytic lymphohistiocytosis (HLH) is a serious haematologic condition that can be related to various diseases, including tuberculosis (TB). The patient is a previously healthy 26-year-old man, originally from western Africa, admitted to hospital for fever and weight loss. Given the results of a computed tomography (CT) scan, ocular examination and microbiologic tests, miliary TB with pulmonary, lymph nodal and ocular involvement was diagnosed. Following the introduction of antitubercular treatment (ATT), an increase in inflammation indexes and severe pancytopenia were observed; at this point, the patient presented with six of the eight diagnostic criteria for HLH, and a diagnosis of HLH secondary to TB was raised. Therefore, HLH treatment with a high dose of dexamethasone was started, with a good clinical response. We performed a literature review of TB-related HLH, which shows a high mortality rate. ATT is necessary to ensure patient survival to remove the antigenic driver. Our patient developed HLH after the initiation of ATT as a paradoxical reaction, which may be linked to the release of antigens due to the bactericidal effect of ATT.

Impact of rapid-antiretroviral therapy in a cohort of treatment-naïve migrants living with HIV in a high income setting.

BACKGROUND: We evaluated the effect of rapid ART (RA) compared to delayed ART (DA) on viral load suppression (viral load <50 cp/mL) and loss to follow-up (LTFU) in a cohort of migrants living with HIV (MLWHs) in Italy. METHODS: Data were retrospectively gathered from MLWHs who began care at the Infectious and Tropical Diseases Unit of the Careggi University Hospital from January 2014 to December 2022. RA was defined as antiretrovirals prescribed within 7 days of HIV diagnosis. The study ended on April 30, 2023, or upon patient LTFU. Chi-square and non-parametric tests assessed differences in categorical and continuous variables, respectively. Kaplan-Meyer survival analysis was performed to estimate the probability of loss to follow-up. Cox regression analysis was performed to evaluate factors associated with a loss to follow-up. RESULTS: 87 MLWHs were enrolled: 20 (23%) on RA and 67 (77%) on DA. In the RA group there were more PLWH with a previous AIDS event (p < .001) however, there was no significant difference in the LTFU rates between the groups (aHR 0.6, 95%CI 0.1-3.1; p = .560; Logrank = 0.2823). Being an out-of-status MLWH was the only predictor of LTFU. By 6 months, virological suppression was achieved in 61.2% (n = 41) in DA and 70.0% in the RA group (n = 14) (Logrank p = .6747). CONCLUSIONS: RA did not significantly affect LTFU rates or the achievement of viral load suppression. The study suggests that further research is needed to assess the impact of RA in high income settings.

Antiviral combination regimens as rescue therapy in immunocompromised hosts with persistent COVID-19.

The management of severe/prolonged SARS-CoV-2 infections in immunocompromised hosts is still challenging. We describe nine patients with hematologic malignancies with a history of unsuccessful SARS-CoV-2 treatment receiving antiviral combination treatment for persistent infection at a tertiary hospital in central Italy (University Hospital of Careggi, Florence). Combination treatments consisted of nirmatrelvir/ritonavir plus molnupiravir (n = 4), nirmatrelvir/ritonavir plus remdesivir (n = 4) or remdesivir plus molnupiravir (n = 1) for 10 days, in some cases associated with sotrovimab. Combinations were generally well tolerated. One patient obtained viral clearance but died due to the underlying disease. In eight cases, clinical and virological success was confirmed by radiological follow-up. Antivirals combination is likely to become a mainstay in the future management of COVID-19 among immunocompromised patients, but knowledge in this field is still very limited and prospective studies on larger cohorts are urgently warranted.
