The number of people with HIV (PWH) aged 50 years or older continues to steadily increase. The convergence of age- and HIV-related complications in these individuals presents a challenge for both patients and clinicians alike. New findings continue to emerge, as numerous researchers evaluate the combined impact of these two factors on quality of life, physiological systems, and mental health in PWH. Since its first occurrence in 2009, the International Workshop on HIV and Aging has served as a multidisciplinary meeting to share basic biomedical data, clinical trial results, treatment strategies, and epidemiological recommendations, toward better understanding and outcomes among like-minded scientific professionals. In this article, we share a selection of key findings presented in plenary talks at the 11th Annual International Workshop on HIV and Aging, held virtually from September 30, 2020 to October 2, 2020. We will also address the future directions of HIV and aging research, to further assess how the aging process intersects with chronic HIV.

Objective: Challenging differential diagnosis. Background: The differential diagnosis for a parotid mass is broad, including infectious, autoimmune, and neoplastic etiologies. In people with HIV, regardless of viral suppression or immune status, neoplastic causes are more common. This report describes the evaluation of a woman with a large parotid mass, with an ultimate diagnosis of multiple myeloma with extramedullary plasmacytoma. Case Report: A 51-year-old woman with HIV infection presented with headache, weight loss, and right facial mass that was present for 5 years but more rapidly enlarging in the prior year. CD4 count was 234 cells/mL, and HIV RNA was 10 810 copies/mL. Physical examination was significant for a large deforming right-sided facial mass, decreased sensation in the V1 and V2 distributions, and right-sided ophthalmoplegia and ptosis. MRI and PET/CT scan confirmed a metabolically active large parotid mass with extension into the cavernous sinus. An IgG kappa monoclonal spike was present on serum protein electrophoresis. Incisional biopsy of the facial mass showed atypical lymphoid cells with plasmablastic and plasmacytic morphology with a high mitotic rate and proliferation index. She was diagnosed with R-ISS stage II IgG kappa multiple myeloma with extramedullary plasmacytoma, and initiated on chemotherapy, radiation, and antiretroviral therapy. Conclusions: A rapidly enlarging parotid mass should prompt timely evaluation and biopsy for definitive diagnosis, particularly in immunocompromised patients, including people with HIV. Extramedullary plasmacytomas have a more aggressive disease process in people with HIV and are associated with high-risk multiple myeloma and progression, as seen in this patient.

Certain comorbidities known to increase the risk of poor outcomes in COVID-19 exist at higher rates in people with HIV; people aging with HIV (PAWH) face additional risk due to the association of advanced age with COVID-19 mortality. Cognitive and functional deficits and social barriers have been identified in cohorts of people aging with HIV. It is postulated that the COVID-19 pandemic potentially threatens PAWH disproportionately to the general population, both in mortality risk due to age and comorbidities, and in potential deleterious effects of policies that seek to drastically limit in-person interaction and access to healthcare systems. A description of and preliminary data from a demonstration project to improve geriatric assessments of people with HIV over age 50 in an urban HIV clinic are presented, in support of this theory. Advice is offered on key strategies utilized to continue to provide care to PAWH during the COVID-19 pandemic, including transition to telemedicine, vaccination, revision of staff roles, repurposing of funding, and a new reliance on available local resources.

Background Serotonin toxicity (also referred to as serotonin syndrome) results from medications that affect the neurotransmitter serotonin. The antibiotic linezolid and the opioids methadone and buprenorphine are all reported to cause serotonin toxicity, but the degree of risk with use of linezolid in combination with methadone or buprenorphine is unknown. Methods We conducted a retrospective cross-sectional analysis of adult patients hospitalized from November 2015 to October 2019 who were administered linezolid in combination with methadone and/or buprenorphine within 24 hours and a subgroup that received the combination for ≥3 days. Cases of serotonin toxicity were identified from the clinical notes in the electronic medical record and were classified as possible or definite based on the clinical record. The Hunter diagnostic criteria were retrospectively applied. Results There were 494 encounters in which linezolid was administered concurrently with methadone and buprenorphine. The mean patient age was 42.5 years, and 52.4% of encounters were of female patients. The mean duration of concurrent administration was 1.9 days. There were 106 encounters with a duration of concurrent administration ≥3 days (mean, 5.4 days). Two cases of possible serotonin toxicity and 0 cases of definite serotonin toxicity occurred; neither possible case met the Hunter criteria from the available information. Possible cases occurred in 0.40% of all encounters and 1.89% of encounters with ≥3 days of overlap (upper 1-sided 95% CI, 0.87% and 4.06%). Conclusions Serotonin toxicity occurring during the administration of linezolid in combination with methadone and/or buprenorphine occurred rarely among 494 hospital encounters, including 106 encounters with ≥3 days of overlap. Limitations include potential missed diagnoses of serotonin toxicity and short durations of overlap. Further study evaluating the short-term risk of this combination is needed.

Validated MPV NAAT from a rectal swab was not available for this patient, but this has been utilized in another case series to diagnose monkeypox proctitis.[3] If the current outbreak continues, it is inevitable that additional patients with the significantly compromised immune function will contract MPV. Prior reports of monkeypox in immunocompromised patients have been limited to persons living with HIV (PLWH),[[2], [4], [6]] with no cases reported in SOT recipients (PubMed advanced search for "transplant" and "monkeypox", 9/22/22). Keywords: monkeypox; HIV; solid organ transplant; proctitis; immunocompromised EN monkeypox HIV solid organ transplant proctitis immunocompromised 1 3 3 02/23/23 20230201 NES 230201 INTRODUCTION An outbreak of non-travel-associated human monkeypox was recognized in May 2022 in non-endemic regions spanning multiple countries, with monkeypox virus (MPV) clade 2 (formerly West African clade) implicated as the cause.[1] Across case series, patients are almost exclusively adult gay, bisexual, and other men who have sex with men (GBMSM), have high rates of co-occurring HIV and bacterial sexually transmitted infections,[[2], [4], [6]] and some are presenting with anogenital lesions preceding rash or without rash.[[2]] Treatment recommendations suggest that those with immunocompromising conditions are at higher risk of severe disease,[8] but experience in patients with non-HIV related immunocompromise is currently absent.

As care of persons living with human immunodeficiency virus (HIV; PWH) has transitioned from management of opportunistic infections to management of conditions associated with older age, new models of geriatric consultation are needed. The authors, who represent 9 clinics across North America and the United Kingdom, provided their insights on models of geriatric consultation for older PWH. Three models of geriatric consultation are delineated: outpatient referral/consultation, combined HIV/geriatric multidisciplinary clinic, and dually trained providers within 1 clinical setting. A patient-centered approach and the use of expertise across disciplines were universally identified as strengths. Logistical barriers and the reluctance of older PWH to see a geriatric care provider were identified as barriers to implementing these models. Although the optimal model of geriatric consultation depends on a region's resources, there is value in augmenting the training of infectious disease providers to include principles of geriatric care.

Salmonella osteomyelitis is known to occur in immunocompromised and sickle cell disease patients. It rarely occurs in other hosts. We present a case of chronic femoral osteomyelitis due to S. enterica serovar Typhi seen in a Maryland resident. Potential risk factors included traveling to an endemic area as well as a newly diagnosed sickle cell trait and thalassemia trait. It is postulated that less severe hemoglobinopathies may also contribute to an elevated risk of Salmonella osteomyelitis.
