HIV-infected Latin American asylum seekers in Madrid, Spain, 2022: A prospective cohort study from a major gateway in Europe.

BackgroundRecent migration trends have shown a notable entry of Latin American asylum seekers to Madrid, Spain.AimTo characterise the profile of asylum-seeking Latin American migrants who are living with HIV in Spain and to outline the barriers they face in accessing HIV treatment.MethodsA prospective cohort study was conducted between 2022 and 2023 with a 6-month follow-up period. Latin American asylum seekers living with HIV were recruited mainly from non-governmental organisations and received care at an HIV clinic in a public hospital in Madrid.ResultsWe included 631 asylum seekers. The primary countries of origin were Colombia (30%), Venezuela (30%) and Peru (18%). The median age was 32 years (interquartile range (IQR): 28-37), and 553 (88%) were cis men of which 94% were men who have sex with men. Upon their arrival, 49% (n = 309) lacked social support, and 74% (n = 464) faced barriers when attempting to access the healthcare system. Upon entry in Europe, 500 (77%) participants were taking antiretroviral therapy (ART). At their first evaluation at the HIV clinic, only 386 (61%) had continued taking ART and 33% (n = 209) had detectable plasma HIV-1 RNA levels. Six months later, 99% took ART and 98% had achieved an undetectable viral load.ConclusionsLatin American asylum seekers living with HIV in Madrid, Spain encountered barriers to healthcare and to ART. One-third of these individuals presented detectable HIV viral load when assessed in the HIV clinic, highlighting this as an important public health issue.

Epidemiological and Clinical Characteristics of Patients Admitted to a Secondary Hospital with Suspected MPOX Virus Infection: Is HIV Playing a Role?

MPOX (monkeypox) is a zoonotic viral disease, endemic in some Central and West African countries. However, in May 2022, cases began to be reported in non-endemic countries, demonstrating community transmission. Since the beginning of the outbreak, different epidemiological and clinical behaviors have been observed. We conducted an observational study at a secondary hospital in Madrid to characterize suspected and confirmed cases of MPOX epidemiologically and clinically. Besides the general descriptive analysis, we compared data between HIV-positive and HIV-negative subjects; 133 patients were evaluated with suspected MPOX, of which 100 were confirmed. Regarding positive cases, 71.0% were HIV positive, and 99.0% were men with a mean age of 33. In the previous year, 97.6% reported having sex with men, 53.6% used apps for sexual encounters, 22.9% practiced chemsex, and 16.7% went to saunas. Inguinal adenopathies were significantly higher in MPOX cases (54.0% vs. 12.1%, p < 0.001), as the involvement of genital and perianal area (57.0% vs. 27.3% and 17.0% vs. 1.0%, p = 0.006 and p = 0.082 respectively). Pustules were the most common skin lesion (45.0%). In HIV-positive cases, only 6.9% had a detectable viral load, and the mean CD4 count was 607.0/mm3. No significant differences were observed in the disease course, except for a greater tendency towards the appearance of perianal lesions. In conclusion, the MPOX 2022 outbreak in our area has been related to sexual intercourse among MSM, with no severe clinical cases nor apparent differences in HIV and non-HIV patients.

HCV, HIV AND HBV rapid test diagnosis in non-clinical outreach settings can be as accurate as conventional laboratory tests.

Point of care rapid diagnostic tests (POC-RDT) for Hepatitis C virus (HCV), Human Immunodeficiency virus (HIV) and Hepatitis B virus (HBV), are ideal for screening in non-clinical outreach settings as they can provide immediate results and facilitate diagnosis, allowing high risk population screening. The aim of this study was to compare POC-RDT with laboratory conventional tests. A total of 301 vulnerable evaluable subjects (drug users, migrants and homeless population) were recruited at a mobile screening unit in outreach settings in Madrid. Fingerprick whole blood capillary samples were tested using the SD BIOLINE HCV POC-RDT, Determine HIV Early Detect and Determine HBsAg 2, and the results were assessed against the LIAISON XL HCV, HIV and Murex-HBsAg-Quant, reference assays, respectively. The feasibility and user satisfaction of the POC-RDT were evaluated through a questionnaire. The resolved sensitivity and resolved specificity and their 95% confidence intervals (95% CI) were as follows, respectively: SD-BIOLINE-HCV: 98.8% (95% CI 93.4, 100.0) and 100.0% (95% CI 98.3, 100.0); Determine HIV Early Detect: 100% (95% CI 85.2, 100.0) and 100% (95% CI 98.7, 100); and Determine HBsAg 2: 66.7% (95% CI 9.4, 99.2) and 100.0% (95% CI 98.7, 100.0). As expected, the number of subjects with a confirmed positive result for HBsAg was very low (n = 4). Therefore, the analytical sensitivity has been evaluated in addition: The Determine HBsAg 2 test demonstrated 100% sensitivity for standard concentrations ≥ 0.125 IU/mL. The subject questionnaire yielded positive feedback for most subjects. The POC-RDT fingerprick blood collection method was well received, and the tests demonstrated a comparable clinical performance with conventional tests in outreach settings and vulnerable high-risk populations.
