RESUMO
Background: cytomegalovirus (CMV) retinitis, cerebral and ocular toxoplasmosis are common infections in patients with acquired immunodeficiency syndrome (AIDS). Material and methods: this is a case of a 46-year-old female with previous Kaposi's sarcoma, diagnosed with an HIV infection two weeks prior to hospitalization. Blood test at diagnosis showed a CD4+ count of 77 cell/µL and HIV-RNA 3.758.745 copies/mL. Therapy with bictegravir/emtricitabine/tenofovir alafenamide fumarate was started and clinical, viroimmunological and microbiological investigations were performed. Results: the patient went to our hospital for the onset of left occipito-parietal headache and blurred vision. Brain CT and MRI were performed which did not show focal lesions or vascular alterations. Syphilis serology was negative, Toxoplasma gondii serology showed positive IgG and negative IgM, serum CMV-DNA was 31.184 IU/mL. Eye fundus evidenced intraretinal hemorrhages, fluorescein angiography and computed optical tomography documented cottony exudates, retinal hemorrhages and vitreous involvement. Therapy with valganciclovir was initiated for suspicion of CMV retinitis. About a month later, the patient reported blurred vision for which she was re-admitted. Ocular fundus showed a cottony lesion near the macula. Molecular test on vitreous body was positive for Toxoplasma gondii, while on cerebrospinal fluid it was negative; in addition, an MRI of the brain with contrast medium was performed which showed an area of altered hyperintense signal compatible with a diagnosis of Toxoplasma gondii uveitis and neurotoxoplasmosis. Therapy with pyrimethamine and clindamycin (allergy for sulfonamide reported by the patient) was started. Allergy counseling was performed with the execution of allergy tests (patch test) with negative result; therefore the administration of clindamycin was replaced with sulfadiazine. A month following the start of anti-toxoplasma therapy, there was a clinical and radiological improvement. Conclusions: despite progressive developments in the management of PLWH, in this case two different kind of opportunistic infection are found in a late-presenter patient. In particular, two aspects can be highlighted. The first one is that, in the setting of an highly impaired immune system, clinical presentation can be deceptive and more than one opportunistic infection can be observed together in the same patient. The second aspect is that after starting antiretroviral therapy, a rapid improvement of viro-immunologic parameters has been documented, probably leading to an immune reconstitution inflammatory syndrome (IRIS).
RESUMO
ABSTRACT: The occurrence of COVID-19 pandemic had a significant negative effect on health care systems over the last year. Health care providers were forced to focus mainly on COVID-19 patients, neglecting in many cases equally important diseases, both acute and chronic. Therefore, also screening and diagnostic strategies for HIV could have been significantly impaired.This retrospective, multicenter, observational study aimed at assessing the number and characteristics of new HIV/AIDS diagnoses during COVID-19 pandemic in Italy and compared characteristics of people living with HIV at diagnosis between pre- and post-COVID-19 era (2019 vs 2020).Our results showed a significant reduction of HIV diagnoses during pandemic. By contrast, people living with HIV during pandemic were older and were diagnosed in earlier stage of disease (considering CD4+ T cell count) compared to those who were diagnosed the year before. Moreover, there was a significant decrease of new HIV diagnoses among men who have sex with men, probably for the impact of social distancing and restriction applied by the Italian Government. Late presentation incidence, if numbers in 2020 were lower than those in 2019, is still an issue.Routinely performing HIV testing in patients with suspected SARS-CoV-2 infection is identifying and linking to care underdiagnosed people living with HIV earlier. Thus, combined tests (HIV and SARS-CoV-2) should be implemented in patients with SARS-CoV-2 symptoms overlapping HIV's ones. Lastly, our results lastly showed how urgent implementation of a national policy for HIV screening is necessary.

Currently approved 2-drug therapies are as effective as 3-drug regimens but could potentially lead to increased cancer risk due to less efficient immune recovery. We conducted a longitudinal cohort study in a tertiary Italian hospital to investigate HIV+ patients starting a triple therapy (TT) (2 NRTIs +3rd agent) or a dual therapy (DT) (3TC/FTC+boosted-PI, boosted-DRV+RAL, and 3TC/FTC or RPV+DTG) regimen between 2009 and 2018. The effect of DT (vs. TT) on tumor onset was evaluated by the multivariable Cox regression and the marginal structural Cox model, after estimating the inverse probability of treatment weights (IPTW). One thousand one hundred and seven patients who had a median follow-up of 4.2 person-years (py) were evaluated; 69.2% were males, with a median age of 43 years. Overall 2,513 treatments were started during the study period (479 DT, 2,034 TT). Eight tumors occurred over 965 py with DT and 35 over 3,817 py during TT (p = .797). In the Cox regression, DT did not predict an increased risk of tumor compared with TT (HR 1.14; p = .757) after adjusting for potential confounders. A marginal structural model using IPTW (HR 0.68; p = .328) and stabilized IPTW (HR 0.69; p = .361) confirmed this result. Preliminary findings from our cohort do not suggest an increased risk of tumors with DT compared to TT.

Background: Biomarkers of systemic inflammation predict non-AIDS events and overall mortality in virologically suppressed HIV-1-infected patients. Objectives: To determine whether switching to a dual antiretroviral maintenance therapy was associated with modification of biomarkers of systemic inflammation as compared with continuation of successful standard triple therapy. Methods: In this substudy of the randomized ATLAS-M trial, we compared in virologically suppressed patients the impact at 1 year of simplification to a dual therapy with atazanavir/ritonavir plus lamivudine versus maintaining atazanavir/ritonavir plus two NRTI triple therapy on markers of systemic inflammation. Plasma levels of interleukin-6, C-reactive protein (CRP), soluble CD14 (sCD14) and D-dimer were quantified by ELISA at baseline and at 48 weeks. Results: A subset of 139 of 266 randomized patients with available samples was analysed: 69 in the triple therapy arm and 70 in the dual therapy arm. The baseline biomarker levels were comparable between randomization arms. No significant differences in changes from baseline to week 48 were observed between arms (dual therapy versus triple therapy): IL-6, -0.030 versus -0.016 log10 pg/L; CRP, +0.022 versus +0.027 log10 pg/mL; sCD14, -0.016 versus +0.019 log10 pg/mL; and D-dimer, -0.031 versus +0.004 log10 pg/mL. A history of cancer was associated with higher baseline levels of IL-6 (P = 0.002) and CRP (P = 0.049). No relationship was observed between baseline biomarker level and persistent residual viraemia, HIV-1 DNA load, plasma lipids and other potential explanatory variables. Conclusions: Simplification with atazanavir/ritonavir plus lamivudine does not affect plasma markers of systemic inflammation in virologically suppressed patients. The association between these findings and clinical outcomes requires further evaluation.
