Background: The optimal timing for initiation of antiretroviral therapy (ART) in HIV-positive patients with cryptococcal meningitis (CM) has not, as yet, been compellingly elucidated, as research data concerning mortality risk and the occurrence of immune reconstitution inflammatory syndrome (IRIS) in this population remains inconsistent and controversial.Method: The present multicenter randomized clinical trial was conducted in China in patients who presented with confirmed HIV/CM, and who were ART-naïve. Subjects were randomized and stratified into either an early-ART group (ART initiated 2–5 weeks after initiation of antifungal therapy), or a deferred-ART group (ART initiated 5 weeks after initiation of antifungal therapy). Intention-to-treat, and per-protocol analyses of data for these groups were conducted for this study.Result: The probability of survival was found to not be statistically different between patients who started ART between 2–5 weeks of CM therapy initiation (14/47, 29.8%) vs. those initiating ART until 5 weeks after CM therapy initiation (10/55, 18.2%) (p = 0.144). However, initiating ART within 4 weeks after the diagnosis and antifungal treatment of CM resulted in a higher mortality compared with deferring ART initiation until 6 weeks (p = 0.042). The incidence of IRIS did not differ significantly between the early-ART group and the deferred-ART group (6.4 and 7.3%, respectively; p = 0.872). The percentage of patients with severe (grade 3 or 4) adverse events was high in both treatment arms (55.3% in the early-ART group and 41.8% in the deferred-ART group; p=0.183), and there were significantly more grade 4 adverse events in the early-ART group (20 vs. 13; p = 0.042).Conclusion: Although ART initiation from 2 to 5 weeks after initiation of antifungal therapy was not significantly associated with high cumulative mortality or IRIS event rates in HIV/CM patients compared with ART initiation 5 weeks after initiation of antifungal therapy, we found that initiating ART within 4 weeks after CM antifungal treatment resulted in a higher mortality compared with deferring ART initiation until 6 weeks. In addition, we observed that there were significantly more grade 4 adverse events in the early-ART group. Our results support the deferred initiation of ART in HIV-associated CM.Clinical Trials Registration:www.ClinicalTrials.gov, identifier: ChiCTR1900021195.

Abstract Background: Cytomegalovirus retinitis (CMVR) is an important opportunistic infection (OI) occurring mainly in patients with acquired immunodeficiency syndrome (AIDS), and has the potential to cause severe visual impairment and blindness among AIDS patients. Subsequent to the adoption and implementation of widespread antiretroviral therapy (ART), the prognosis of AIDS-associated CMVR has been substantially improved. Nevertheless, there remains some controversy with regards to the optimal timing for ART initiation in patients with an established CMVR diagnosis. We therefore designed the present study in order to investigate the optimal timing for ART initiation in AIDS/CMVR patients.Methods: This will be a prospective, randomized controlled trial to be performed at 17 hospitals in mainland China. A total of 300 participants with CMVR will be randomly assigned to an early ART initiation group (ART initiation within 2 weeks after anti-CMV therapy), or a deferred ART initiation group (initiation of ART more than 2 weeks after anti-CMV therapy) at a 1:1 ratio. All participants will receive 48-weeks of follow-up after anti-CMV therapy initiation. Our primary outcome will be the incidence of visual loss (to a visual acuity worse than 20/40 or 20/200) in the two groups during the 48-week follow-up period. Secondary outcomes will include changes in HIV virological suppression and serum CD4+ T-cell counts, the incidence of mortality, retinitis progression (movement of the peripheral border of a CMV lesion ≥ ½ disc diameter, or occurrence of a new CMV lesion), retinal detachment, immune recovery uveitis (IRU), and other OIs and adverse events between the two study groups during the 48 weeks of follow-up. Discussion:The study aims to investigate the optimal timing for ART initiation in AIDS/CMVR patients. We hope to be able to extract robust clinical evidence for use in optimal AIDS/CMVR management should our trial be successful.Trial registration: This research was registered as one of the twelve clinical trials under the name of a general project “A study for precision diagnosing and treatment strategies in difficult-to-treat AIDS cases and HIV-infected patients with highly fatal or highly disabling opportunistic infections”, ChiCTR1900021195.

Abstract Infections are the most frequent complication during chemotherapy-induced neutropenia and fungal infections are a cause of morbility and mortality. We have retrospectively analysed our patients who received an antifungal treatment for a possible, probable or proven fungal infection. Between April 1998 and July 2005 we analysed 750 consecutive phases of treatment for 309 patients admitted at our Institution. The treatment phases were for: acute leukemia 253, lymphoma 168, multiple myeloma 215, chronic leukemia 19, severe aplastic anemia 12, solid tumors (breast, renal, testis cancer) 44, multiple sclerosis 5, others 34. Among them 474 (63.2%) were at high risk for infections (the risk was considered high for lenght of neutropenia, diagnosis of acute leukemia, allogeneic BMT). There were 31 allo-BMT and 145 autologous BMT. The antifungal therapy was for a first short period (until mid-1999) an empirical treatment (when fever persisted more than 4 days despite antibiotic therapy during neutropenia); after, only when another sign (clinical or radiological or microbiological) of fungal infection was present, the patients received an antifungal treatment. We treated also a small cohort of patients with a secondary prophylactic regimen (they were patients who developed a fungal infection during a previous treatment). Seventy-four patients received an antifungal treatment (10% of all phases and 15.6% of high-risk phases). The infection was possible (empiric treatment) in 4 cases, probable (presumptive therapy) in 37 cases, proven in 16 cases; 17 cases of secondary prophylaxis. The first administered drug was Amphotericin B deoxycholate (AMB) in 31/74 cases (41.9%), Abelcet (ABCT) in 6/74 (8%), Liposomal Amphotericin B (LAMB) in 18/74 cases (24.4%), Voriconazole (VCZ) in 3/74 cases (4%) and Caspofungin (Caspo) in 16/74 cases (21.7%). The schedule of treatment was: AMB 0.7–1 mg/Kg in 6 hours, ABCT 5 mg/Kg in 3 hours, LAMB 3 mg/Kg in 1 hour, VCZ 6 mg/Kg bid iv in 2 hours for 3 days then 4 mg/Kg bid orally, Caspo 70 mg iv on the first day and then 50 mg in 1 hour. For the empiric treatment the first drug was AMB 3 and Caspo 1; for presumptive therapy AMB 18, ABCT 4, LAMB 4, VCZ 1 and Caspo 10. For proven infections AMB 8, ABCT 1, LAMB 5, VCZ 1, Caspo 1; for secondary prophylaxis AMB 2, ABCT 1, LAMB 9, VCZ 1 and Caspo 4. The isolated fungi were Candida albicans 4, Aspergillus spp 4, Scedosporium 2, Fusarium solani 1, others (only histological isolation) 5. The days of treatment were 7.64 for AMB, 6.88 for ABCT, 14.22 for l-AMB, 14.1 for Caspo and 30 for VCZ. Adverse events with AMB and ABCT were similar: mild to moderate renal insufficiency (50%), fever (50%), ipokalemia (75%), chills (30%); with VCZ visual disturbances (80%) and mild hepatic insufficiency (20%); with LAMB mild renal insufficiency (10%) and low back pain (5%); no adverse events with Caspo were noted. AMB was discontinued 9/31 times (29%), ABCT 1/6 (17%) for adverse events. Our conclusions are that AMB and ABCT are problematic drugs for their poor tolerability, they need an important premedication, a hyperhydration regimen and a long-time administration; moreover for a great cohort of patients we have had to discontinue the drug. The other drugs seems to be better tolerated; no organ failures were seen and the treatment duration was longer for Caspo and LAMB. Even if the cost of these two drugs is major than others the lack of adverse events and the new mechanism of action of Caspo make these drugs probably better than ABCT, AMB and VCZ.

Abstract Background Antiretroviral therapy (ART) initiation during acute and early HIV infection (AEHI) limits HIV reservoir formation and may facilitate post-ART control but is logistically challenging. We evaluated the performance of new AEHI diagnostic criteria from a multi-national prospective study of ART initiation during AEHI. Methods ACTG 5354 enrolled adults at 30 sites in the Americas, Africa, and Asia who met any one of six criteria based on combinations of results of HIV RNA, HIV antibody, Western blot or Geenius assay, and/or the signal-to-cutoff (S/CO) ratio of the ARCHITECT HIV Combo Ag/Ab CMIA or GS HIV COMBO Ag/Ab EIA. HIV infection and Fiebig stage were subsequently confirmed by centralized testing. Results From 2017-2019, 195 participants were enrolled with median age 27 (interquartile range 23-39) years. Thirty (15.4%) were female. ART was started by 171 (87.7%) on the day of enrollment and 24 (12.3%) the next day. AEHI was confirmed in 188 (96.4%) participants after centralized testing, four (2.0%) participants were retrospectively found to have chronic infection, and three (1.5%) found not to have HIV discontinued ART and were withdrawn. Retrospectively, a nonreactive or indeterminate HIV antibody on the Geenius assay combined with ARCHITECT S/CO ≥10 correctly identified 99 of 122 (81.2%) Fiebig II-IV AEHI cases with no false-positive results. Conclusions Novel AEHI criteria incorporating ARCHITECT S/CO into diagnostic algorithms facilitated rapid and efficient ART initiation without waiting for an HIV RNA result. These new criteria may facilitate AEHI diagnosis, staging, and immediate ART initiation in future research studies and clinical practice.

Abstract Background: Pneumocystis pneumonia (PCP) is a common AIDS-related opportunistic infection. Recent reports estimate that more than 400,000 HIV patients develop PCP each year globally. However, the timing of antiretroviral therapy (ART) initiation for HIV infected patients with PCP is still controversial, and the benefits and risks of early initiation of ART are not completely clear. We thus designed this study in order to determine the optimal timing for ART initiation for HIV-positive patients with moderate to severe PCP.Methods: This study will be an open-labelled, multi-center, prospective, randomized controlled trial. A total of 200 subjects will be randomized to an early ART initiation group (≤14 days after PCP diagnosis), and a deferred ART initiation group (>14 days after PCP diagnosis) at a 1:1 ratio. All subjects will be followed up for 48 weeks after starting ART. The primary outcome is incidence of disease progression (including new opportunistic infections and all-cause mortality) at week 48. The secondary endpoints are the changes in CD4 counts from baseline at week 12, week 24 and week 48, the degree of virological suppression (HIV-RNA<50 copies/mL) at week 24 and week 48, the rate of development of PCP-associated immune reconstitution inflammatory syndrome (IRIS), and adverse events(AEs) at each visit.Discussion: We hope that the results of this study will reveal the optimal timing for initiation of ART in HIV-infected patients with moderate to severe PCP.Trial registration: This trial was registered as one of the twelve trials under the name of a general project at chictr.org.cn on February 1, 2019, and the registration number of the general project is ChiCTR1900021195.

The most recent version of the Southern African HIV Clinicians Society’s adult antiretroviral therapy (ART) guidelines was published in December 2014. In the 27 August 2015 edition of the New England Journal of Medicine, two seminal randomised controlled trials that addressed the optimal timing of ART in HIV-infected patients with high CD4 counts were published: Strategic timing of antiretroviral therapy (START) and TEMPRANO ANRS 12136 (Early antiretroviral treatment and/or early isoniazid prophylaxis against tuberculosis in HIV-infected adults). The findings of these two trials were consistent: there was significant individual clinical benefit from starting ART immediately in patients with CD4 counts higher than 500 cells/μL rather than deferring until a certain lower CD4 threshold or clinical indication was met. The findings add to prior evidence showing that ART reduces the risk of onward HIV transmission. Therefore, early ART initiation has the public health benefits of potentially reducing both HIV incidence and morbidity. Given this new and important evidence, the Society took the decision to provide a specific update on the section of the adult ART guidelines relating to when ART should be initiated.
