RESUMEN
INTRODUCTION: Rapid initiation of ART after HIV diagnosis is recommended for individual and public health benefits. However, certain clinical and ART-related considerations hinder immediate initiation of therapy. METHODS: An open-label, single-arm, single-centre 48-week prospective clinical trial involving ART-naïve HIV-diagnosed adults who started bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) within a week from the first hospital visit, before the availability of baseline laboratory and genotype results. The primary aim was to determine the proportion of people with at least one condition that would hinder immediate initiation of any recommended ART regimen other than BIC/FTC/TAF. Clinicaltrials.gov: NCT04416906. RESULTS: We included 100 participants: 79% men, 64% from Latin America, median age 32 years. According to European AIDS Clinical Society (EACS) and US Department of Health and Human Services 2023 guidelines, 11% (95%CI 6; 19) of participants had at least one condition that made any ART different from BIC/FTC/TAF less appropriate for a rapid ART strategy. Seventy-nine percent of the people started BIC/FTC/TAF within the first 48 hours of their first hospital visit. There were 16 early discontinuations (11 lost to follow-up). By week 48, 92% (95%CI 86; 98) of the participants of the ITT population with observed data achieved viral suppression. Eight grade 3-4 adverse events (AEs), five serious AEs and six ART-related AEs were identified. Adherence remained high. CONCLUSIONS: BIC/FTC/TAF is an optimal treatment for rapid initiation of ART. However, additional strategies to improve retention in care must be implemented.

OBJECTIVES: Our aim was to determine the prevalence and characteristics of people with HIV on antiretroviral therapy (ART) with multidrug resistance (MDR; confirmed resistance to three or more [or resistance to two or more plus contraindication to one or more] core ART classes) and limited treatment options (LTOs) in Spain. METHODS: This was an observational, retrospective, multicentre, cross-sectional chart review study undertaken in five reference Spanish centres. Participants were people with HIV on ART with MDR and LTOs (detectable viral load [HIV-RNA >200 copies/mL], treatment-limiting drug-drug interaction [DDI], or intolerance precluding the use of one or more ART classes). Prevalence, demographic/clinical characteristics, and treatment options were assessed. Logistic regression analyses were used to identify MDR-associated variables. RESULTS: Of 14 955 screened people with HIV, 69 (0.46%) presented with MDR and 23 (0.15%) had LTOs. The population analysed was 73.9% male with a median age of 54.0 years; the median time since HIV diagnosis was 26.5 years, and median CD4+ cell count was 511.0 cells/µL. The only factor significantly associated with MDR (univariate analysis) was CD4+ cell count. Injection drug use was the most common transmission route. Comorbidities (mainly endocrine and cardiovascular disorders; 34.8% affecting HIV management) and concomitant treatments were frequent. No recent opportunistic infections were reported. Patients had been exposed to the following ART: nucleoside analogue reverse transcriptase inhibitors (100%), protease inhibitors (95.6%), non-nucleoside analogue reverse transcriptase inhibitors (87.0%), and integrase strand transfer inhibitors (82.6%). The available fully active drugs were dolutegravir (39.1%), bictegravir (30.4%), and raltegravir (21.7%). CONCLUSIONS: The prevalence of people with HIV with MDR and LTOs in Spain is very low, with approximately half of those studied not exhibiting virological suppression. Low CD4+ cell counts were associated with MDR. These findings may help address the impact and treatment needs of these patients and prevent clinical progression and transmission of MDR HIV.

BACKGROUND: The use of bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) is based on the results of robust clinical trials. OBJECTIVES: To assess the effectiveness and safety of BIC/FTC/TAF in treatment-naïve (TN) and treatment-experienced (TE) people with HIV using available real-world cohort studies. METHODS: Systematic review and meta-analysis of publications and communications identified via Boolean search in Medline, PubMed and Embase, and conference abstracts reporting retrospective real-world use of BIC/FTC/TAF, published until 31 January 2024. The primary endpoint was the proportion of TN and TE people with HIV with viral load (VL)â<â50â copies/mL at 48â weeks while on treatment. RESULTS: Of the 38 identified publications and conference abstracts, for the present analysis we included 12 publications (comprising 792 TN and 6732 TE individuals). For the three publications including 507 TN participants reporting the primary outcome, VL suppression was 97% [95% confidence intervals (CI): 89-100]. For the nine publications including 4946 TE participants reporting the primary outcome, VL suppression was 95% (95% CI: 94-96), with suppression >93% in all studies. Total discontinuations at 48â weeks in TE individuals were 3% (95% CI: 2-5), 1% (95% CI: 0-2) due to side effects. A total of four publications with 151 TE individuals with previous presence of M184V substitution were identified, reporting a suppression rate at 48â weeks of 95% (95% CI: 88-100). CONCLUSIONS: Real-world studies demonstrate low discontinuation rates and high rates of virologic suppression in individuals treated with BIC/FTC/TAF, both TN and TE with and without previous detection of M184V substitution.

BACKGROUND: A broadened clinical spectrum of concomitant complications emerges among the escalating incidence of substance use, particularly within the 'chemsex' context. This case exemplifies the profound neurotoxic repercussions and neurological risk of chemsex in a young HIV-positive male and addresses the multifaceted challenges of such evolving paradigms in substance utilization. CLINICAL FINDING: After consuming cannabis, poppers, methamphetamine, and cocaine, a 28-year-old HIV-positive male exhibited significant neurological and cognitive impairment. The initial presentation included dysarthria and profound anterograde amnesia. Laboratory findings showed leukocytosis with a PCR of 3 mg/dl - elevated cerebrospinal fluid protein levels with no cells. Urine toxicology returned positive for cannabis and amphetamines. A brain CT scan revealed bilateral and symmetrical hippocampi and pale globes hypodensity, indicative of toxic-metabolic encephalopathy. MRI further identified lesions in the globus pallidus, cerebellum, and hippocampi. Following the detection of toxic encephalopathy, Initial neuropsychological was performed screening using the Montreal Cognitive Assessment (MoCA), which highlighted immediate memory deficits. An in-depth neuropsychological assessment conducted 3 weeks later included the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV), the Rey Auditory Verbal Learning Test (RAVLT), and tests for visuospatial skills, motor functions, and memory recall. The evaluations revealed pronounced anterograde amnesia, persistent long-term memory inconsistencies, and notable executive function challenges, detailed in Table 1. CONCLUSIONS: The detailed analysis of this case underpins the severe neurological consequences that can manifest from heavy substance use. Comprehensive diagnostic evaluations, including neuroimaging and neuropsychological assessments, are crucial in elucidating the full spectrum of substance-induced cognitive impairments. There is an urgent need for enhanced public awareness and preventative measures, especially in the context of chemsex, to bring forth multifaceted health, social, and government implications that modern society must adeptly navigate.
RESUMEN
We investigated differences in mpox clinical outcomes in people with HIV (PWH) and without HIV (PWoH) and the impact of vaccination in Catalonia, Spain. We used surveillance data and the PISCIS HIV cohort. We included all confirmed mpox cases (May-December 2022). Of 2122 mpox cases, the majority had mild disease, 56% were Spanish, and 24% were from Latin America. A total of 40% were PWH, with a median CD4+T-cell of 715 cells/µL; 83% had HIV-RNA < 50 copies/mL; and 1.8% CD4+T-cell < 200 cells/µL. PWH had no increased risk for complications, except those with CD4+T-cell < 200 cells/µL. PWH with CD4+T-cell < 200 cells/µL were more likely to be from Latin America, had more generalized exanthema, and required hospitalization more frequently (p = 0.001). Diagnosis of other sexually transmitted infections (STIs) was common, both at mpox diagnosis (17%) and two years before (43%). Dose-sparing smallpox intradermal vaccination was accompanied by a sharp decrease in mpox incidence in both populations (p < 0.0001). In conclusion, unless immunosuppressed, PWH were not at increased risk of severe disease or hospitalization. Mpox is a marker of high-risk sexual behavior and was associated with high HIV and STI rates, supporting the need for screening in all mpox cases. Ethnicity disparities demonstrate the need for interventions to ensure equitable healthcare access. Dose-sparing smallpox vaccination retained effectiveness.
RESUMEN
Background: New regimens may provide better tolerability, convenience, and safety for nonoccupational human immunodeficiency virus (HIV) postexposure prophylaxis (PEP). For this reason, we evaluated the single-tablet regimen of doravirine/lamivudine/tenofovir disoproxil fumarate (DOR/3TC/TDF) for 28 days. Methods: This was a prospective, open-label, single-arm trial including individuals with potential HIV-1 exposure within 72 hours. The primary endpoint was noncompletion of PEP at day 28. Secondary endpoints were adverse effects, adherence, and rate of seroconversion. We performed follow-up at day 7, week 4, and week 12. Results: Between September 2019 and March 2022, the study enrolled 399 individuals. Median age was 30 (interquartile range [IQR], 27-36) years, and 91% (n = 364) were male. The mode of exposure was sex between men in 84% (n = 331) of cases; risk assessment for HIV-1 transmission was considered as "high" in 97% (n = 385) of the participants. Median time from exposure to consultation was 24 (IQR, 13-40) hours. Noncompletion of PEP was 29% (n = 114) (95% confidence interval [CI], 24%-33%) and 20% (n = 72) (95% CI, 16%-25%) per modified intention-to-treat. Main reasons for noncompletion were loss to follow-up (n = 104 [91%]) and intolerance (n = 8 [7%]). Older age was associated with a lower risk of premature discontinuation (OR, 0.94; P < .001). One hundred twenty-three (31%) participants reported adverse events, mostly mild and self-limited (82%); discontinuation occurred in 8 cases (2%). Adherence to PEP in the assessed users was 96%. There were no HIV seroconversions. Conclusions: DOR/3TC/TDF is a well-tolerated option for nonoccupational PEP. Clinical Trials Registration. NCT04233372.
RESUMEN
BACKGROUND: The use of dolutegravir/lamivudine is based on solid clinical trials; however, real-world data remain limited. OBJECTIVES: To provide data on the clinical use and effectiveness of dolutegravir/lamivudine in persons with HIV in a real-world scenario. PATIENTS AND METHODS: Retrospective, single-centre and observational study. We included all adults starting dolutegravir/lamivudine since November 2014. We reported all demographic, virological and immunological variables at baseline and assessed effectiveness [on treatment (OT), modified ITT (mITT) and ITT in those persons who reached 6 and 12 month follow-ups (M6 and M12). RESULTS: Of the 1058 persons, 9 were treatment-naive; the final analysis included 1049 treatment-experienced people with HIV. Median (IQR) follow-up was 1 (0.3-1.6) years, with 81% and 63% persons reaching M6 and M12, respectively. The longest use of dolutegravir/lamivudine was 7.4 years. Per OT, mITT and ITT, HIV-RNAâ<â50 copies/mL was 97%, 92% and 81% (M6) and 98%, 90% and 80% (M12), respectively. Females [adjusted risk ratio, aRR (95% CI): 1.69 (1.19-2.40)]; immediate, previous PI-based regimen [aRR (95% CI): 1.67 (1.09-2.56)]; and viral load (VL)â≥â50 copies/mL at dolutegravir/lamivudine initiation [aRR (95% CI): 3.36 (2.32-4.88)] were independently associated with lack of effectiveness at M12; other demographic, immunological and virological variables like previous M184V/I substitutions or virological failure, were unrelated. Of the total, 944 (90%) continued dolutegravir/lamivudine. The most frequent known reason for discontinuation was toxicity [48 (46%) cases]. CONCLUSIONS: In our real-world experience, virological suppression rates were high for treatment-experienced persons on dolutegravir/lamivudine; however, we identified subgroups with a higher risk of lack of effectiveness at M12, who may benefit from closer follow-ups.

Human immunodeficiency virus (HIV) infection is considered a chronic disease. Antiretroviral therapy has allowed persons with HIV (PLWHIV) to achieve the 90-90-90 objectives proposed by the World Health Organization for 2020; but an additional challenge is getting an adequate health-related quality of life. A determining factor in the health-related quality of life of PLWHIV is the health care they perceive to receive. In this sense, we aimed to assess the perception of the outpatient care provided and to identify possible areas for improvement in a single-center, cross-sectional study at the HIV unit of Hospital Clínic, Barcelona. We sought patient reported experience measures by an anonymous e-survey with 11 statements based on a 1 to 6 Likert scale, and a final question measuring user satisfaction and loyalty through the Net Promoter Score (NPS). All PLWHIV with at least a clinical visit between January 1, 2020 and October 14, 2021 were invited. Of 5493 PLWHIV e-mailed, 1633 (30%) responded to the survey. The overall evaluation of clinical care was very favorable. The evaluation of the physical environment and facilities and the time spent in the waiting room received the lowest scores. According to the Net Promoter Score test results, 66% of respondents were willing to recommend this service, and 11% were not. Thus, monitoring patient reported experience measures in PLWHIV actively receiving outpatient care in our hospital allowed to identify the users' perception on quality of the care received, to determine the rate of satisfaction with the care, and to identify areas for improvement.

BackgroundEpidemiological and immunovirological features of people living with HIV (PLWH) can vary by sex.AimTo investigate, particularly according to sex, characteristics of PLWH who consulted a tertiary hospital in Barcelona, Spain, in 1982-2020.MethodsPLWH, still in active follow-up in 2020 were retrospectively analysed by sex, age at diagnosis, age at data extraction (December 2020), birth place, CD4+ cell counts, and virological failure.ResultsIn total, 5,377 PLWH (comprising 828 women; 15%) were included. HIV diagnoses in women appeared to decrease from the 1990s, representing 7.4% (61/828) of new diagnoses in 2015-2020. From 1997, proportions of new HIV diagnoses from patients born in Latin America seemed to increase; moreover, for women born outside of Spain, the median age at diagnosis appeared to become younger than for those born in Spain, with significant differences observed in 2005-2009 and 2010-2014 (31 vs 39 years (p = 0.001), and 32 vs 42 years (p < 0.001) respectively), but not in 2015-2020 (35 vs 42 years; p = 0.254). Among women, proportions of late diagnoses (CD4+ cells/mm3 < 350) were higher than men (significantly in 2015-2020: 62% (32/52) vs 46% (300/656); p = 0.030). Initially, virological failure rates were higher in women than men, but they were similar in 2015-2020 (12% (6/52) vs 8% (55/659); p = 0.431). Women ≥ 50 years old represented 68% (564/828) of women actively followed up in 2020.ConclusionsWomen still have higher rates of late HIV diagnoses than men. Among currently-followed-up women, ≥ 50 year-olds, who need age-adapted care represent a high percentage. Stratifying PLWH by sex matters for HIV prevention and control interventions.

BACKGROUND: People living with HIV have accounted for 38-50% of those affected in the 2022 multicountry mpox outbreak. Most reported cases were in people who had high CD4 cell counts and similar outcomes to those without HIV. Emerging data suggest worse clinical outcomes and higher mortality in people with more advanced HIV. We describe the clinical characteristics and outcomes of mpox in a cohort of people with HIV and low CD4 cell counts (CD4 <350 cells per mm3). METHODS: A network of clinicians from 19 countries provided data of confirmed mpox cases between May 11, 2022, and Jan 18, 2023, in people with HIV infection. Contributing centres completed deidentified structured case report sheets to include variables of interest relevant to people living with HIV and to capture more severe outcomes. We restricted this series to include only adults older than 18 years living with HIV and with a CD4 cell count of less than 350 cells per mm3 or, in settings where a CD4 count was not always routinely available, an HIV infection clinically classified as US Centers for Disease Control and Prevention stage C. We describe their clinical presentation, complications, and causes of death. Analyses were descriptive. FINDINGS: We included data of 382 cases: 367 cisgender men, four cisgender women, and ten transgender women. The median age of individuals included was 35 (IQR 30-43) years. At mpox diagnosis, 349 (91%) individuals were known to be living with HIV; 228 (65%) of 349 adherent to antiretroviral therapy (ART); 32 (8%) of 382 had a concurrent opportunistic illness. The median CD4 cell count was 211 (IQR 117-291) cells per mm3, with 85 (22%) individuals with CD4 cell counts of less than 100 cells per mm3 and 94 (25%) with 100-200 cells per mm3. Overall, 193 (51%) of 382 had undetectable viral load. Severe complications were more common in people with a CD4 cell count of less than 100 cells per mm3 than in those with more than 300 cells per mm3, including necrotising skin lesions (54% vs 7%), lung involvement (29% vs 0%) occasionally with nodules, and secondary infections and sepsis (44% vs 9%). Overall, 107 (28%) of 382 were hospitalised, of whom 27 (25%) died. All deaths occurred in people with CD4 counts of less than 200 cells per mm3. Among people with CD4 counts of less than 200 cells per mm3, more deaths occurred in those with high HIV viral load. An immune reconstitution inflammatory syndrome to mpox was suspected in 21 (25%) of 85 people initiated or re-initiated on ART, of whom 12 (57%) of 21 died. 62 (16%) of 382 received tecovirimat and seven (2%) received cidofovir or brincidofovir. Three individuals had laboratory confirmation of tecovirimat resistance. INTERPRETATION: A severe necrotising form of mpox in the context of advanced immunosuppression appears to behave like an AIDS-defining condition, with a high prevalence of fulminant dermatological and systemic manifestations and death. FUNDING: None.

Monkeypox is a zoonosis that is spread mainly through direct contact with fluids and skin lesions of infected people with vesicles still active. Although the virus was isolated for the first time in 1958 and the first human case was identified in a child in 1970, in the Democratic Republic of the Congo, the disease has progressively increased its incidence in Africa reaching in May 2022 sustained transmission outside this continent. As it is a newly introduced virus in our health system, it is necessary to learn the epidemiological pattern in a different environment from that of traditionally endemic areas and to know the available antiviral treatments, as well as the prophylactic measures that could be considered, knowing that as a virus emerging in our regions, scientific evidence is still limited. There are antivirals that have been shown, in animal models, to effectively combat the disease with very good clinical tolerance. This disease has also forced us to review the characteristics of smallpox vaccines, because they have shown a protective effect against monkeypox. For this reason, it is important to have a document that compiles all the scientific information published in this regard.

INTRODUCTION: Pre-Exposure Prophylaxis (PrEP) is a biomedical intervention to prevent HIV infection in seronegative people at high risk of becoming infected. This strategy was endorsed in October 2019 by the Spanish Ministry of Health. OBJECTIVE: To present the PrEP initial experience in the HIV Unit of the Hospital Clínic of Barcelona, paying special attention to the analysis of the vulnerability factors in the cohort. MATERIALS AND METHODS: Retrospective, descriptive study. The epidemiological, sociodemographic, and clinical characteristics of the users included in the program during the first year are analyzed, paying particular attention to Infections, risky practices, and substance use. RESULTS: 190 individuals were included, 177 men and 12 trans women with a mean age of 35 years (8 SD). 70% had higher education, and half had Spanish nationality. An average of 10 couples per trimester and 60% reported unprotected anal sex. 31% had at least one positive PCR for STIs, with N. gonorrhoeae being the most prevalent microorganism (51%) and the rectal sample the most affected (21%). 63% reported chemsex use, 19% polydrug use, and 8% "slamming". Half expressed concern about consumption and/or sexual practices and 25% the need for help. CONCLUSIONS: The PrEP user profile attended in our Hospital Unit justifies the creation of multidisciplinary teams that allow us to provide holistic attention to the sexual life of these people.

INTRODUCTION: Pre-exposure prophylaxis (PrEP) is effective for HIV prevention, but the PrEP care continuum also involves improving PrEP awareness, uptake, adherence, and retention in care. Users' awareness is often compromised because of vulnerability factors and risk behaviors, such as chemsex practice or specific substance use, which could lead to risk compensation. Correct adherence and retention in care are essential to achieve the full effectiveness of PrEP. This study describes changes in users' risk behaviors and sexually transmitted infections (STIs), as well also PrEP care continuum details. METHODS: This was a descriptive single-center retrospective study including adults at high HIV risk screened between November 2019 and June 2021 in the PrEP program of our hospital. Demographic, behavioral, STI, adherence, and retention in care variables were assessed. Data were collected from medical records and self-report questionnaires. RESULTS: A total of 295 people were included, 94% men and 5% transgender women, with a mean age of 34 years (SD 10) and 10% sex workers. At baseline, 55% disclosed chemsex practice and 3% slamming. During follow-up, condom use for anal intercourse decreased from 41% to 13% (p ≤ 0.0001) and one HIV infection was detected; other risk behaviors and STIs remained stable. Chemsex, group sex, fluid exchange, and condomless anal intercourse were related to STI risk. Adherence was correct in 80% of users, and retention in care was 57%. Discontinuations and loss to follow-up were high, mainly affecting transgender women, sex workers, and people practicing fisting. CONCLUSION: PrEP program implementation in our hospital was adequate, since it allowed, in a population at high HIV risk, overall users' risk behaviors and STIs to remain stable, with only one HIV diagnosis during the follow-up. We should target specific strategies to improve adherence and retention in care, as vulnerable subgroups at higher risk of loss to follow-up are identified.
RESUMEN
BACKGROUND: Between May and November, 2022, global outbreaks of human monkeypox virus infection have been reported in more than 78 000 people worldwide, predominantly in men who have sex with men. We describe the epidemiological and clinical characteristics of monkeypox virus infection in cisgender (cis) and transgender (trans) women and non-binary individuals assigned female sex at birth to improve identification and understanding of risk factors. METHODS: International collaborators in geographical locations with high numbers of diagnoses of monkeypox virus infection were approached and invited to contribute data on women and non-binary individuals with confirmed monkeypox virus infection. Contributing centres completed deidentified structured case-report spreadsheets, adapted and developed by participating clinicians, to include variables of interest relevant to women and non-binary individuals assigned female at birth. We describe the epidemiology and clinical course observed in the reported infections. FINDINGS: Collaborators reported data for a total of 136 individuals with monkeypox virus infection who presented between May 11 and Oct 4, 2022, across 15 countries. Overall median age was 34 years (IQR 28-40; range 19-84). The cohort comprised 62 trans women, 69 cis women, and five non-binary individuals (who were, because of small numbers, grouped with cis women to form a category of people assigned female at birth for the purpose of comparison). 121 (89%) of 136 individuals reported sex with men. 37 (27%) of all individuals were living with HIV, with a higher proportion among trans women (31 [50%] of 62) than among cis women and non-binary individuals (six [8%] of 74). Sexual transmission was suspected in 55 (89%) trans women (with the remainder having an unknown route of transmission) and 45 (61%) cis women and non-binary individuals; non-sexual routes of transmission (including household and occupational exposures) were reported only in cis women and non-binary individuals. 25 (34%) of 74 cis women and non-binary individuals submitted to the case series were initially misdiagnosed. Overall, among individuals with available data, rash was described in 124 (93%) of 134 individuals and described as anogenital in 95 (74%) of 129 and as vesiculopustular in 105 (87%) of 121. Median number of lesions was ten (IQR 5-24; range 1-200). Mucosal lesions involving the vagina, anus, or oropharynx or eye occurred in 65 (55%) of 119 individuals with available data. Vaginal and anal sex were associated with lesions at those sites. Monkeypox virus DNA was detected by PCR from vaginal swab samples in all 14 samples tested. 17 (13%) individuals were hospitalised, predominantly for bacterial superinfection of lesions and pain management. 33 (24%) individuals were treated with tecovirimat and six (4%) received post-exposure vaccinations. No deaths were reported. INTERPRETATION: The clinical features of monkeypox in women and non-binary individuals were similar to those described in men, including the presence of anal and genital lesions with prominent mucosal involvement. Anatomically, anogenital lesions were reflective of sexual practices: vulvovaginal lesions predominated in cis women and non-binary individuals and anorectal features predominated in trans women. The prevalence of HIV co-infection in the cohort was high. FUNDING: None.

Monkeypox is a zoonosis that is spread mainly through direct contact with fluids and skin lesions of infected people with vesicles still active. Although the virus was isolated for the first time in 1958 and the first human case was identified in a child in 1970, in the Democratic Republic of the Congo, the disease has progressively increased its incidence in Africa reaching in May 2022 sustained transmission outside this continent. As it is a newly introduced virus in our health system, it is necessary to learn the epidemiological pattern in a different environment from that of traditionally endemic areas and to know the available antiviral treatments, as well as the prophylactic measures that could be considered, knowing that as a virus emerging in our regions, scientific evidence is still limited. There are antivirals that have been shown, in animal models, to effectively combat the disease with very good clinical tolerance. This disease has also forced us to review the characteristics of smallpox vaccines, because they have shown a protective effect against monkeypox. For this reason, it is important to have a document that compiles all the scientific information published in this regard.
RESUMEN
BACKGROUND: Unprotected and fragile elderly people in nursing homes experienced the highest mortality rates during the initial coronavirus disease 2019 (COVID-19) pandemic. OBJECTIVE: Our aim was to study the role of two oral anti-inflammatory drugs, colchicine and prednisone, in elderly patients with COVID-19 in geriatric centers. METHODS: A phase II/III, randomized, controlled, multicenter clinical trial was performed in a geriatric population comparing the efficacy and safety of an oral combination of prednisone (60 mg/day for 3 days) and colchicine (at loading doses of 1-1.5 mg/day for 3 days, followed by 0.5 mg/day for 11 days) with the standard treatment, based on intravenous dexamethasone. Primary endpoints assessed the efficacy in reducing death or the modified endpoint death/therapeutic failure to the study drugs over a 28-day period, while secondary endpoints included safety, laboratory changes, and additional therapies used. RESULTS: Fifty-four patients (35 female/19 male) were enrolled, 25 (46.3%) of whom were allocated to the experimental arm and 29 (53.7%) to the control arm. At day 28, no differences in deaths were observed. The combination of mortality or therapeutic failure occurred in 12 (45.13%) patients receiving dexamethasone and 6 (28.13%) patients receiving colchicine/prednisone, resulting in a reduction of risk difference (RD) of - 17% (p = 0.17), with an average reduction of 39% (risk ratio [RR] 0.61) in patients receiving colchicine/prednisone (p = 0.25). Control patients received higher amounts of additional glucocorticoids (p = 0.0095) over a longer time frame (p = 0.0003). Colchicine/prednisone significantly reduced ferritin levels at day 14, as well as D-dimer and lactate dehydrogenase (LDH) levels at day 28. Adverse events were similar in both groups. CONCLUSIONS: The combination colchicine/prednisone compared with intravenous dexamethasone has shown a remarkable trend to increase disease survival over a 28-day period in elderly patients requiring oxygen therapy in geriatric centers, without safety issues. CLINICAL TRIAL REGISTRY: Clinical Trials Registration Number: NCT04492358.

INTRODUCTION: Proviral HIV DNA integrated within CD4 T-cells maintains an archive of viral variants that replicate during the course of the infection, including variants with reduced drug susceptibility. We considered studies that investigated archived drug resistance, with a focus on virologically suppressed patients and highlighted interpretative caveats and gaps in knowledge. RESULTS: Either Sanger or deep sequencing can be used to investigate resistance-associated mutations (RAMs) in HIV DNA recovered from peripheral blood. Neither technique is free of limitations. Furthermore, evidence regarding the establishment, maintenance, expression and clinical significance of archived drug-resistant variants is conflicting. This in part reflects the complexity of the HIV proviral landscape and its dynamics during therapy. Clinically, detection of RAMs in cellular HIV DNA has a variable impact on treatment outcomes, modulated by the drugs affected, treatment duration and additional determinants of virological failure, including those leading to suboptimal drug exposure. CONCLUSIONS: Sequencing cellular HIV DNA can provide helpful complementary information in treatment-experienced patients with suppressed plasma HIV RNA who require a change of regimen. However, care should be taken when interpreting the results. Presence of RAMs is not necessarily a barrier to treatment success. Conversely, even the most sensitive sequencing techniques will fail to provide a comprehensive view of the HIV DNA archive. To inform treatment decisions appropriately, the overall clinical and treatment history of a patient must always be considered alongside the results of resistance testing. Prospective controlled studies are needed to validate the utility of drug resistance testing using cellular HIV DNA.
RESUMEN
BACKGROUND: Since May 2022, a new outbreak of monkeypox has been reported in several countries, including Spain. The clinical and epidemiological characteristics of the cases in this outbreak may differ from those in earlier reports. OBJECTIVES: To document the clinical and epidemiological characteristics of cases of monkeypox in the current outbreak. METHODS: We conducted a prospective cross-sectional study in multiple medical facilities in Spain to describe the cases of monkeypox in the 2022 outbreak. RESULTS: In total, 185 patients were included. Most cases started with primarily localized homogeneous papules, not pustules, in the probable area of inoculation, which could be cutaneous or mucous, including single lesions. Generalized small pustules appeared later in some of them. Heterogeneous lesions occurred during this generalized phase. All patients had systemic symptoms. Less common lesions included mucosal ulcers (including pharyngeal ulcers and proctitis) and monkeypox whitlows. Four patients were hospitalized, none died. Smallpox vaccination and well-controlled HIV disease were not associated with markers of severity. Contact during sex is the most likely mechanism of transmission. In this outbreak, cases have been described in men who have sex with men and are strongly associated with high-risk sexual behaviours. Seventy-six per cent of the patients had other sexually transmitted diseases upon screening. CONCLUSIONS: The clinical findings in this outbreak differ from previous findings and highly suggest contact transmission and initiation at the entry site. The characterization of the epidemiology of this outbreak has implications for control. What is already known about this topic? Monkeypox eruption is described as consisting of pustules. The roles of HIV and previous smallpox vaccination in the prognosis are unknown. The transmission route was initially described as respiratory droplets and was later suggested to be via sexual contact. What does this study add? Initial lesions at the probable inoculation area were homogeneous and papular (pseudopustules). Generalized small pustules appeared later in some of them. Heterogeneous lesions occurred during this generalized phase. All patients had systemic symptoms. Less common signs included mucosal ulcers (including pharyngeal ulcers and proctitis) and monkeypox whitlows. Well-controlled HIV and previous smallpox vaccination were not associated with severity. No patient died. The data support the hypothesis of transmission via contact during sex. Although this might change, the outbreak is currently limited mostly to men who have sex with men, with high-risk factors for sexually transmitted diseases.

Pre-exposure prophylaxis (PrEP) is a biomedical intervention that has demonstrated efficacy in HIV prevention in individuals at high-risk, among them chemsex users. Out of 190 PrEP users followed at Hospital Clinic of Barcelona until October 2020, 89% reported drug use, and 63% disclosed that they had engaged in chemsex practices, initiated in 64% of cases within the past year. Twenty-one percent used 3 or more drugs simultaneously, being GHB/GBL, nitrites, sildenafil, and methamphetamine the most prevalent combination. Eight percent reported slamming. Forty-one percent described having had negative experiences and 8% did not remember the last time they had sober sex. Methamphetamine, mephedrone, GHB/GBL, and having had open relationships, group sex, double penetration, and fisting were significantly more prevalent. Forty-nine percent admitted being worried about chemsex use, and 18% said they needed help. A comprehensive, interdisciplinary approach is mandatory to enable the attainment of a healthy approach to one's sex life.
RESUMEN: La PrEP es una intervención biomédica eficaz en la prevención del VIH en personas con alto riesgo, entre ellas las personas que practican chemsex. De los 190 usuarios de PrEP seguidos en el Hospital Clínic de Barcelona hasta octubre de 2020, el 89% refirió utilizar drogas y el 63% en contexto de chemsex, iniciando el consumo el 64% durante el último año. El 21% refería policonsumo, siendo GHB/GBL, nitritos, sildenafilo y metanfetamina la combinación más prevalente. El 8% reportó slamming. El 41% describió haber tenido experiencias negativas y el 8% no recordaba la última vez que tuvo sexo sobrio. Metanfetamina, mefedrona, GHB/GBL y haber tenido relaciones abiertas, sexo en grupo, doble penetración y fisting fueron significativamente más frecuentes. El 49% refirió estar preocupado por la práctica de chemsex y el 18% necesitar ayuda. Un abordaje integral e interdisciplinar mejoraría el acompañamiento global de la sexualidad en estas personas.
