Prevalence of Comorbidities and Polypharmacy in a Historically Minoritized Community and Their Impact on Virologic Suppression in Persons with HIV.

Improved life expectancy from advances in antiretroviral therapy (ART) has been followed by a rise in comorbidities and polypharmacy in this aging population. Historically, polypharmacy has been associated with suboptimal virologic outcomes in persons with HIV, although data in the current ART era and among historically marginalized populations in the United States are limited. We measured the prevalence of comorbidities and polypharmacy, evaluating their impact on virologic suppression. This retrospective IRB-approved cross-sectional study reviewed health records of adults with HIV on ART and receiving care (≥2 visits) in 2019 at a single center in a historically minoritized community. Virologic suppression (HIV RNA <200 copies/mL) based on polypharmacy (≥5 non-HIV medications) or multimorbidity (≥2 chronic conditions) was evaluated. Logistic regression analyses were performed to identify factors associated with virologic suppression, with age, race/ethnicity, and CD4 < 200 cells/mm3 as covariates. Of the 963 individuals that met the criteria, 67%, 47%, and 34% had ≥1 comorbidity, multimorbidity, and polypharmacy, respectively. The cohort demographics were: mean of 49 years (range, 18-81), 40% cisgender women, 46% Latinx individuals, 45% Black individuals, 8% White individuals. Virologic suppression rates were 95% among patients with polypharmacy compared with 86% in those with a lower pill burden (p = 0.0001). The odds of virologic success were higher for individuals with polypharmacy [adjusted odds ratio, aOR = 2.3 (95% confidence interval, CI: 1.2-4.4)] and Latinx identity [aOR = 2.4 (95% CI: 1.5-3.8)], but lower if a CD4 count <200 cells/mm3 [aOR = 0.07 (95% CI: 0.04-0.1)]. The comorbidity burden was higher than previously described, which are driving polypharmacy rates. In the current ART era, polypharmacy is not inherently associated with worse virologic outcomes.

Evaluation of Statin Prescribing Practices and Predictors of Statin Underutilization in Persons With HIV.

BACKGROUND: Persons with HIV (PWH) have an increased risk of cardiovascular disease (CVD) compared with those without HIV. Despite the increased risk, PWH are less likely to be prescribed statin therapy compared with the general population. The purpose of this study is to describe the statin prescribing practices of an outpatient HIV clinic and identify potential predictors of statin underutilization. METHODS: This study was a retrospective, single-center chart review of PWH ages 40-79 years receiving care at an HIV clinic. Statin eligibility, statin prescribing practices, and appropriateness of statin therapy were evaluated. Logistical regression analyses were conducted to assess for predictors of underutilization of statin therapy. RESULTS: Of the 606 patients, statin therapy was indicated in 362 patients (60%). Among those with a statin indication, 60.2% were prescribed appropriate statin therapy, 11.6% were prescribed statin therapy but not at the indicated intensity, and 28.2% were not prescribed statin therapy. Tobacco use ( P = 0.0023) was identified as a predictor of statin underutilization. The odds of statin prescribing were higher for those with clinical atherosclerotic CVD ( P = 0.004) and hypertension ( P = 0.017). CONCLUSION: Statin underutilization was significantly higher in PWH smoking tobacco and PWH without atherosclerotic CVD or low-density lipoprotein-cholesterol 190 mg/dL or higher. In addition, this study highlights the need for more robust CVD prevention efforts in PWH. Identifying predictors of statin underutilization may aid in elucidating where gaps in cardiovascular prevention care may exist.

Hepatitis C virus micro-elimination within a clinic for people with HIV: challenges in the home stretch.

OBJECTIVES: To describe a pharmacist-led campaign aimed at reducing the proportion of people with HIV with ongoing chronic hepatitis C virus (HCV) infection and delineating barriers to HCV care in this patient population. METHODS: An electronic report and retrospective chart review were used to identify patients who remained with HCV infections after a previous treatment initiative. A clinical pharmacist and pharmacy resident approached the remaining HCV patients during their routine visits for HIV care to offer and coordinate direct-acting antiviral (DAA) treatment. The primary end-point was to compare the prevalence of chronic HCV before and after the intervention period. Barriers to care were also evaluated, with logistic regression performed to identify predictors of sustained virologic response (SVR) attainment. RESULTS: Forty-six patients were included in the analysis (4.2% of clinic population), with HCV prevalence falling to 0.6% (six patients) by the end of the study (p < 0.0001). The HCV care cascade in the cohort was as follows: 70% agreed to and received DAA therapy, 63% initiated therapy, and 50% achieved SVR. The top barriers to care at baseline included recreational drug use (67%), poor engagement in care (61%), and mental health disorders (28%). Poor engagement in care and active recreational drug use were associated with decreased odds of achieving SVR in bivariate analysis. CONCLUSIONS: A coordinated effort can make strides towards reducing the overall burden of HCV in this challenging population. The HCV care cascade remains tied to the HIV continuum of care, with poor engagement in care remaining an important rate-limiting step impeding micro-elimination.

A Rare Case of Vertebral Osteomyelitis and Bilateral Psoas Abscess From an Unknown Source.

We present a case of a 31-year-old Filipino man with vertebral osteomyelitis and bilateral psoas abscesses. Vertebral osteomyelitis is a rare infection of the bone and bone marrow that affects the vertebral column. The patient's initial presentation included a 1-week history of cough, fatigue, diarrhea, fevers, and a 40-pound weight loss. An extensive workup including a computed tomography (CT) scan of the abdomen and pelvis demonstrated bilateral psoas abscesses with subcutaneous air tracking into the right flank. Blood cultures revealed Escherichia coli, Streptococcus anginosus, and Bacteroides. However, with an unclear primary source of infection, the most likely causative factor we believed to be due to immobility.

A Case of Cryptococcal Hepatitis in an HIV Patient with a Negative Serum Cryptococcal Antigen.

Infectious Cryptococcus neoformans occurs primarily in immunocompromised patients. The primary organ affected is the lungs, but the infection of the central nervous system (CNS) is also be seen. Disseminated cryptococcosis can involve any organ in the body. However, hepatic involvement is rare. Here we discuss a case of cryptococcal hepatitis in a patient who presented with persistently elevated liver enzymes. A 56-year-old Ecuadorian female with no known past medical history presented with fever, abdominal pain, nausea, unintentional weight loss, and diarrhea for two months. Her liver function tests (LFTs) revealed elevated aspartate aminotransferase (AST: 415 U/L), elevated alanine aminotransferase (ALT: 201 U/L), elevated alkaline phosphatase (ALP: 763 U/L), but normal total bilirubin (0.9 mg/dl). Her HIV antigen screening was reactive, and the absolute cluster of differentiation 4 (CD4) helper count was 22 cell/µL. Over the course of her hospital stay, the patient's liver enzymes continued to trend upward, with negative Histoplasma antibodies and negative serum cryptococcal antigen titers. During the second week of hospitalization, her liver enzymes continued to rise with an ALP of 4046 U/L, AST of 436 U/L, and ALT of 276 U/L. With a persistent elevation of the liver enzymes without any definitive cause, an ultrasound-guided biopsy was performed. Pathology revealed cryptococcal hepatitis, and the patient was started on a 15-day course of amphotericin B with an eight-week course of fluconazole 400 mg with LFTs nearly normalizing at six weeks. This case demonstrates an unusual manifestation of cryptococcosis. Our patient did not present with the typical cryptococcal pulmonary or central nervous system infection. Additionally, our patient's serum cryptococcal antigen titers were negative, but biopsy results revealed cryptococcal hepatitis, despite a very high sensitivity and specificity of the serum cryptococcal antigen test. This case demonstrates the importance of maintaining a broad differential, specifically in immunocompromised patients.

Pneumococcal Vertebral Osteomyelitis after Epidural Injection: A Rare Event.

Streptococcus pneumoniae vertebral infections have rarely been reported. Herein, we report a case of pneumococcal vertebral osteomyelitis with paraspinal and epidural abscesses as well as concomitant bacteremia following epidural injection. This will be the second case in the literature reporting pneumococcal vertebral osteomyelitis related to epidural manipulation.

Predictors of loss of hepatitis B surface antigen in HIV-infected patients.

AIM: To study factors associated with loss of hepatitis B surface antigen (HBsAg) in patients co-infected with human immunodeficiency virus (HIV) and hepatitis B virus (HBV). METHODS: We retrospectively reviewed the medical records of 5681 patients followed up at two New York City HIV clinics from January 1999 to May 2007. Clinical and laboratory parameters including baseline and follow-up HIV viral loads, CD4 cell counts, alanine transaminase levels, demographics, presence of hepatitis C infection, and treatment with highly active antiretroviral therapy dually active against both HIV and HBV infection, were analyzed to determine factors associated with loss of HBsAg. RESULTS: Three hundred and fifty five patients (355/5681, 6.84%) were co-infected with HIV and HBV and were evaluated. Of these, 226 patients with more than 12 mo follow-up were included in further analysis to determine factors associated with loss of HBsAg in the long-term follow-up. In the univariate analysis, baseline CD4 cell count was associated with loss of HBsAg (P = 0.052). Cox regression analysis revealed that loss of HBsAg was associated with baseline CD4 cell count > 500 cells/mm(3) (P = 0.016, odds ratio: 76.174, 95% confidence interval: 2.233-2598.481). CONCLUSION: Our study showed an interesting association of loss of HBsAg in HIV-HBV co-infected patients with higher CD4 cell count, suggesting that T-cell cytolytic activity against HBV may still be effective in clearing HBV infection.

Lymphogranuloma venereum in human immunodeficiency virus-infected individuals in New York City.

Lymphogranuloma venereum (LGV), or chlamydial proctitis, is a classic sexually transmitted disease with prominent gastrointestinal manifestations. The disease has received little attention in recent years, especially in relation to human immunodeficiency virus (HIV) infection. However, outbreaks of LGV have been reported in several large cities in Europe and the United States over the past few years, occurring in both HIV-infected and -uninfected individuals, and the reports have been largely limited to the sexually transmitted disease literature. We recently diagnosed four cases of chlamydial proctitis in HIV-infected individuals, who had different clinical presentations but very similar endoscopic and histopathologic features, as well as prompt and complete response to therapy. It is important for gastroenterologists to recognize that LGV may be reemerging as a relevant clinical entity, because of its similarity to inflammatory bowel diseases and its response to treatment with antibiotics.
