Abstract
Identifying barriers to retention in care (RIC) is critical to ending the HIV epidemic in the United States. Therefore, we developed a machine learning model (MLM) to identify predictive factors for RIC in an urban HIV clinic. Our MLM yielded a positive predictive value of 84%, higher than previously reported MLMs. We found that MLM can be used to develop interventional strategies to enhance RIC in HIV care.

Rapidly Enlarging Parotid Mass in a Person Living with HIV: A Case of Multiple Myeloma with Extramedullary Plasmacytoma. AMERICAN JOURNAL OF CASE REPORTS 2023; 24:e938431. [PMID: 37533236 PMCID: PMC10411289 DOI: 10.12659/ajcr.938431] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Revised: 06/29/2023] [Accepted: 05/11/2023] [Indexed: 08/04/2023]
Abstract
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.

Abstract
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.

“A cross-sectional analysis of linezolid in combination with methadone or buprenorphine as a cause of serotonin toxicity.”. Open Forum Infect Dis 2022; 9:ofac331. [PMID: 35899282 PMCID: PMC9310287 DOI: 10.1093/ofid/ofac331] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Accepted: 06/30/2022] [Indexed: 12/03/2022] Open
Abstract
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.

Strengths and Challenges of Various Models of Geriatric Consultation for Older Adults Living with HIV. Clin Infect Dis 2021; 74:1101-1106.

Abstract
As care of persons living with 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 nine different clinics across North America and the United Kingdom, provided their insights on models of geriatric consultation for older individuals living with HIV. Three models of geriatric consultation are delineated: outpatient referral/consultation, combined HIV/geriatric multidisciplinary clinic, and dually-trained providers within one clinical setting. A patient-centered approach and the utilization 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.

Abstract
BACKGROUND Streptococcus pyogenes, or Group A Streptococcus (GAS), is not considered a typical cause of infective endocarditis (IE), but has anecdotally been observed in unexpectedly high rates in people who inject drugs (PWID) at our institution. METHODS All cases of possible or definite GAS IE per Modified Duke Criteria in adults at an academic hospital between 11/15/2015 and 11/15/2020 were identified. Medical records were reviewed for demographics, comorbidities, treatment, and outcomes related to GAS IE. The literature on cases of GAS IE was reviewed. RESULTS Eighteen cases of probable (11) or definite (7) GAS IE were identified; the mean age was 38 years, and the population was predominantly female (56%) and Caucasian (67%), which is inconsistent with local population demographics. Sixteen cases were in people who inject drugs (PWID; 89%); 14 were also homeless, 6 also had HIV (33%), and 2 were also pregnant. Antibiotic regimens were variable due to polymicrobial bacteremia (39%). One patient underwent surgical valve replacement. Four patients (22%) died due to complications of infection. The literature review revealed 42 adult cases of GAS IE, only 17 of which were in PWID (24%). CONCLUSIONS The 16 cases of possible and definite GAS IE in PWID over a 5-year period in a single institution reported nearly doubles the number of cases in PWID from all previous reports. This suggests a potential increase in GAS IE particularly in PWID and PWH, which warrants further epidemiologic investigation.

Legionella longbeachae pneumonia: Case report and review of reported cases in non-endemic countries. IDCases 2021; 23:e01050. [PMID: 33511033 PMCID: PMC7817369 DOI: 10.1016/j.idcr.2021.e01050] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2020] [Revised: 01/10/2021] [Accepted: 01/11/2021] [Indexed: 02/06/2023] Open
Abstract
Legionella longbeachae pneumonia is much less common than Legionella pneumophila pneumonia in most of the world and may evade timely diagnosis in settings that rely primarily on urine antigen testing, which detects Legionella pnuemophila serogroup 1 only. It is, however, widely recognized in Australia and New Zealand, where it is endemic and associated with exposure to compost and potting soils, rather than contaminated water systems as seen with L. pneumophila. L. longbeachae can cause a similar spectrum and severity of illness as L. pneumophila. Here we present a case of a 47-year-old man with L. longbeacheae necrotizing pneumonia following exposure to possibly contaminated soil from a wastewater treatment facility. Initial presentation included cough, chest pain, and dyspnea, and progressed to hypoxic respiratory failure, tension pneumothorax, and cardiac arrest. L. pneumophila urine antigen was negative, but bronchioalveolar lavage samples grew L. longbeachae on buffered charcoal yeast extract agar. A review of cases reported in the literature in non-endemic regions over a 20-year period identified 38 cases in Europe, 33 in Asia, and 8 in North America. Average age was 65, 65 % were male, and 35 % had potentially relevant environmental exposures. L. longbeachae should be considered in cases of severe community acquired pneumonia, particularly following a consistent environmental exposure or if initial testing for other pathogens is unrevealing. A thorough exposure history including questions about contact with potting soil or compost, and utilization of specialized agar for culture can both be key in identifying this pathogen.

Abstract
BACKGROUND Staphylococcus lugdunensis is a coagulase negative Staphylococcus species and frequent human skin commensal with the potential for aggressive infection. Guidance surrounding S. lugdunensis bacteremia (SLB) from a single set of blood cultures is lacking. METHODS A multicenter, retrospective cohort of patients with SLB from at least one blood culture set within the University of Maryland Medical System from 2015 to 2019 is presented. Objectives are to describe baseline characteristics, compare the clinical status and treatment course, and to evaluate the clinical outcomes among patients with SLB in single versus multiple sets. RESULTS Thirty-six patients were included, 24 with one set of blood cultures positive for S lugdunensis and 12 with multiple sets. Baseline characteristics were similar between the groups, though patients with SLB in multiple sets were more commonly on hemodialysis (P = 0.029). Central lines were the most common source (17%). Most (97%) fulfilled systemic inflammatory response syndrome or Souvenir criteria, had an infectious focus on imaging, or had a second positive culture site. Most (78%) were treated as clinically significant. Patients with multiple positive sets were more commonly treated with antibiotics for >2 weeks (P = 0.02). CONCLUSIONS SLB was rare and occurred more frequently as a single set of positive cultures. Patient characteristics and clinical courses were similar between single and multiple set groups. Given the potential severity of S. lugdunensis bacteremia it seems prudent to treat S. lugdunensis in a single blood culture as true bacteremia, pending larger studies and guidelines.

Abstract
Streptococcus pyogenes gynecological infections generally occur in association with childbirth, intra-uterine devices, and other invasive gynecologic procedures, but rarely cause spontaneous pelvic inflammatory disease. We describe a case of a healthy young woman with spontaneous S. pyogenes pelvic inflammatory disease, bacteremia, and shock, and summarize an additional 13 cases found in the literature. The majority were bacteremic and a significant number were also hypotensive. The same proportion had presenting gastrointestinal symptoms as had genitourinary symptoms, masking the diagnosis in many. Many prior case reports postulate a connection with S. pyogenes pharyngitis in a close contact, and an oro-genital route of transmission has been proposed given the exceedingly low rates of genital colonization with S. pyogenes. A high index of suspicion is needed for an accurate and timely diagnosis of this rare but potentially fatal condition.

Abstract
Acute bacterial endocarditis is now common and easily suspected and recognized in the setting of prosthetic valves, injection drug use, or bacteremia with virulent organisms. Conversely, subacute bacterial endocarditis has drastically decreased in incidence, and recognition may be further hampered by the indolent non-specific presentation. Delayed diagnosis is common and can lead to serious complications and fatalities. We describe a patient found to have Streptococcus mutans subacute bacterial endocarditis, who presented with classic risk factors and findings, and who died shortly after presentation due to hemorrhagic conversion of an embolic stroke in the setting of anticoagulation. It is critical that all cases of streptococcal bacteremia be appropriately evaluated and treated, and that Streptococcus spp. not ever be routinely considered a blood culture 'contaminant'.

Abstract
People living with HIV are at high risk for anal cancer (AC); however, the impact of screening for and treatment of precancerous anal lesions on AC incidence remains uncertain. In 2013, we conducted a survey of HIV providers evaluating the perceived need for an institutional AC screening program. Based on an overwhelmingly positive response, we established a dedicated AC screening clinic (including provision of high-resolution anoscopies) embedded within the institutional HIV clinic. Here, we describe that referral of high-risk patients in the first 3 years was lower than expected. Referral patterns suggest that screening practices vary widely among HIV providers within the institution. Anal cancer clinic patients who completed a perception survey rated the value of AC screening as high, with perceived positive health impact, and identified their providers as the main source of information on AC and AC screening. Our findings imply remaining provider-related barriers to AC screening.

Abstract
Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are considered variants of a disease continuum that results in a life-threatening exfoliative mucocutaneous disease. These are categorised as type IV cell-mediated delayed hypersensitivity reactions, and antibiotics are often implicated as a cause. Penicillins and other beta-lactam antibiotics are known to cause both immediate and delayed hypersensitivity reactions. While immediate IgE-mediated cross-reactivity between penicillins and carbapenems is well studied, less information on the risk of type IV delayed cell-mediated cross-reactivity between the two is available. We present a case of meropenem-induced SJS in a patient with documented history of SJS from amoxicillin. There are few cases of cross-reactivity with carbapenems reported in the literature, but based on the potential for life-threatening reaction, it is likely prudent to avoid the use of any beta-lactams in a patient with a history of SJS, TEN or any other severe cutaneous adverse reactions to another beta-lactam antibiotic.

Abstract
A 23-year-old man with a viral-like prodrome developed sudden severe dyspnea and was found to have renal failure, anemia, shock, and diffuse alveolar hemorrhage with acute respiratory distress syndrome, requiring emergent endotracheal intubation and extracorporeal membrane oxygenation (ECMO). Travel and exposure history from peripheral sources revealed that the patient had participated in a 'mud-run' in Hawaii two weeks prior to symptom onset. The patient was subsequently diagnosed with leptospirosis and treated with ceftriaxone and doxycycline. He was discharged on hospital day 13 with full recovery. Leptospirosis is associated with exposure to water, soil, or other matter contaminated with urine of carrier animals. It has been associated with a multitude of activities over time; most recently recreational water-based activities including 'mud-runs' in endemic areas have been added to the list of routes of exposure. This case underscores the importance of obtaining a thorough epidemiological exposure and travel history and being aware of areas of endemicity for life-threatening infections. Additionally, to our knowledge this is the second case of a patient in the United States treated with ECMO for leptospirosis induced pulmonary hemorrhage.

Abstract
An inpatient penicillin allergy skin testing program can be successfully managed by infectious diseases fellows under attending supervision offering a novel practice area for infectious diseases practitioners. Background. A large percentage of patients presenting to acute care facilities report penicillin allergies that are associated with suboptimal antibiotic therapy. Penicillin skin testing (PST) can clarify allergy histories but is often limited by access to testing. We aimed to implement an infectious diseases (ID) fellow-managed PST program and to assess the need for PST via national survey. Methods. We conducted a prospective observational study of the implementation of an ID fellow-managed penicillin allergy skin testing service. The primary outcome of the study was to assess the feasibility and acceptability of an ID fellow-managed PST service and its impact on the optimization of antibiotic selection. In addition, a survey of PST practices was sent out to all ID fellowship program directors in the United States. Results. In the first 11 months of the program, 90 patients were assessed for PST and 76 patients were tested. Of the valid tests, 96% were negative, and 84% with a negative test had antibiotic changes; 63% received a narrower spectrum antibiotic, 80% received more effective therapy, and 61% received more cost-effective therapy. The majority of survey of respondents (n = 50) indicated that overreporting of penicillin allergy is a problem in their practice that affects antibiotic selection but listed inadequate personnel and time as the main barriers to PST. Conclusions. Inpatient PST can be successfully managed by ID fellows, thereby promoting optimal antibiotic use in patients reporting penicillin allergies. This model can increase access to PST at institutions without adequate access to allergists while also providing an important educational experience to ID trainees.

Abstract
Cryptococcosis is an opportunistic invasive fungal infection that is well described and easily recognised when it occurs as meningitis in HIV-infected persons. Malignancy and its treatment may also confer a higher risk of infection with Cryptococcus neoformans, but this association has not been as well described. A case of cryptococcosis in a cancer patient is presented, and all cases of coincident C. neoformans infection and malignancy in adults published in the literature in English between 1970 and 2014 are reviewed. Data from these cases were aggregated in order to describe the demographics, type of malignancy, site of infection, clinical manifestations, treatment and outcomes of cryptococcosis in patients with cancer. Haematologic malignancies accounted for 82% of cases, with lymphomas over-represented compared to US population data (66% vs. 53% respectively). Cryptococcosis was reported rarely in patients with solid tumours. Haematologic malignancy patients were more likely to have central nervous system (P < 0.001) or disseminated disease (P < 0.001), receive Amphotericin B as part of initial therapy (P = 0.023), and had higher reported mortality rates than those with solid tumours (P = 0.222). Providers should have heightened awareness of the possibility of cryptococcosis in patients with haematologic malignancy presenting with infection.
