RESUMO
BACKGROUND: C. auris has become a growing concern worldwide due to increases in incidence of colonization and reports of invasive infections. There are limited data on clinical factors associated with poor outcomes in patients with C. auris bloodstream infection (BSI). METHODS: We assembled a multicenter retrospective cohort of patients with C. auris BSI from two geographics areas in US healthcare settings. We collected data on demographic, clinical, and microbiologic characteristics to describe the cohort and constructed multivariate logistic regression models to understand risk factors for two clinical outcomes, all-cause mortality during facility admission, and blood culture clearance. RESULTS: Our cohort consisted of 187 patients with C. auris BSI (56.1% male, 55.6% age >65 years); 54.6% died by facility discharge and 66.9% (of 142 with available data) experienced blood culture clearance. Pitt bacteremia score at infection onset was associated with mortality (odds-ratio [95% confidence interval]: 1.19 [1.01,1.40] per 1-point increase). Hemodialysis was associated with a reduced odds of microbiologic clearance (0.15 [0.05,0.43]) and with mortality (3.08 [1.27,7.50]). CONCLUSIONS: The Pitt bacteremia score at the onset of C. auris BSI may be a useful tool in identifying patients at risk for mortality. Targeted infection prevention practices in patients receiving hemodialysis may be useful to limit poor outcomes.
RESUMO
BACKGROUND: Men who have sex with men (MSM) and persons living with human immunodeficiency virus (PLWH) were disproportionately affected by global mpox outbreak in 2022. In this retrospective review, we describe epidemiology and clinical characteristics of mpox infection in South Florida with a focus on human immunodeficiency virus (HIV) status. METHODS: This was a retrospective observational study of 198 adult patients with confirmed diagnosis of mpox between 01 January 2020, and 10 September 2022, in two large health systems in South Florida. A descriptive analysis was performed to summarize demographic, clinical and laboratory characteristics, and outcomes of the patients. RESULTS: Young male patients and PLWH were disproportionately represented among patients with mpox. HIV positive patients were less likely to have adenopathy and myalgia and were more likely to have oral or facial lesions. 22.7% of studied patients were diagnosed with one or more concurrent STI at the time of mpox diagnosis. CONCLUSIONS: We suggest screening for sexually transmitted infections and HIV for patients diagnosed with mpox. We suggest prompt consultation or referral to infectious disease specialist if needed for the patients who are diagnosed with mpox especially in the severely immunocompromised host.
RESUMO
The COVID-19 Omicron variant has imposed a tremendous burden on healthcare services. We characterized the types of the Omicron variant-associated hospitalizations and their associations with clinical outcomes. Consecutive adults hospitalized with COVID-19 during the Omicron variant surge period of 1-14 January 2022, were classified into one of three groups based on their clinical presentations on admission: Group 1-primary COVID-19; Group 2-extrapulmonary manifestations of COVID-19; and Group 3-incidental COVID-19. Of the 500 patients who were hospitalized, 51.4% fell into Group 1, 16.4% into Group 2, and 32.2% into Group 3. The patients in Groups 1 and 2 were older, with higher proportions of comorbidities than patients in Group 3. The Group 1 patients had the highest mortality rate (15.6%), followed by Group 2 (8.5%), and Group 3 (0.6%), with adjusted odds ratios (OR) of 22.65 (95% confidence interval [CI], 2.75-239.46; p = 0.004) and 10.95 (95% CI, 1.02-117.28; p = 0.048), respectively, compared to Group 3. Those in Group 1 showed a greater utilization of intensive care services (15.9%), followed by Group 2 (10.9%), and Group 3 (2.5%), with adjusted ORs of 7.95 (95% CI, 2.52-25.08; p < 0.001) and 5.07 (95% CI, 1.34-19.15; p = 0.017), respectively, compared to Group 3. The patients in Groups 1 and 2 had longer hospitalization stays than the patients in Group 3 (p < 0.001 and p = 0.002, respectively). Older age (≥65 years) was an independent factor associated with longer hospital stays (OR = 1.72, 95% CI, 1.07-2.77). These findings can help hospitals prioritize patient care and service planning for future SARS-CoV-2 variants.
RESUMO
Despite increasing rates of renal replacement therapy, data supporting the safe and effective use of HIV treatment guidelines preferred regimens in people on hemodialysis or peritoneal dialysis is limited. Bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) is a guideline recommended initial regimen for most people with HIV with FDA-approval for use in virologically suppressed people receiving chronic hemodialysis; however, the safety and efficacy of BIC/FTC/TAF remains unknown when used in patients on chronic ambulatory peritoneal dialysis (CAPD). We report the first case of BIC/FTC/TAF use in CAPD.

BACKGROUND: The COVID-19 pandemic has posed a tremendous burden on healthcare services. We evaluated its impact on an emergency department (ED)-based opt-out Human immunodeficiency virus (HIV) testing in a public healthcare system. METHODS: The programmatic data of ED-based HIV testing from July 2018 to March 2021 at the Memorial Regional Hospital, Hollywood, Florida was analyzed by interrupted time series analysis to evaluate the immediate and gradual effects of the COVID-19 pandemic on the number of monthly HIV tests, with an interruption point at March 2020. RESULTS: The average number of monthly HIV tests were significantly lower during the pandemic than the pre-pandemic (791 ± 187 vs 1745 ± 266, P < .001). There was a slight decline trend in the number of monthly HIV tests before the pandemic (estimate -10.29, P = .541). HIV testing dramatically decreased during the initial 7 months of the pandemic, compared to the pre-pandemic period, with the largest decline in the number of HIV tests on March 2020 (estimate -678.48, P = .007). HIV testing slightly increased every month (estimate 4.84, P = .891) during the pandemic period, and the number of HIV tests per month rebounded to the pre-pandemic levels by October 2020. CONCLUSIONS: ED-based HIV testing significantly decreased during the initial 7 months of the pandemic in south Florida. Multiple strategies are necessary to maintain HIV testing during this pandemic era.

OBJECTIVE: The aim of the study was to describe implementation of an outpatient antibiotic stewardship program at primary care practices in South Florida and the proportion of appropriate and inappropriate orders and reasons for inappropriateness during the intervention. METHODS: An antibiotic stewardship committee at a large hospital system implemented aspects of The Core Elements of Outpatient Antibiotic Stewardship at outpatient facilities in 2018. Interventions included an education/awareness campaign directed at prescribers (audit and feedback, routine education at prescribers' meetings, availability of updated guidelines in a shared drive and antibiogram via intranet) and patients (posters, tear-off sheets on symptom relief for viral illness). Orders were evaluated using clinical documentation, current antibiogram, and Infectious Diseases Society of America guidelines. An appropriate order was defined as a correct antibiotic and dose/frequency and duration of therapy. An inappropriate antibiotic order was defined as not meeting 1 or more of the abovementioned conditions. Descriptive statistics assessed the data. RESULTS: In this retrospective review of 2934 oral antibiotic orders from January 1 to December 31, 2018, 2565 (87.4%) were necessary while 369 (12.6%) were unnecessary. Of 2565 necessary orders, 1448 (56.5%) were appropriate while 1117 (43.5%) were inappropriate. Of 1117 inappropriate orders, 24.9% had all 3 conditions; 41.5% of inappropriate orders were solely due to wrong duration of therapy. CONCLUSIONS: Although our institution demonstrated commitment to optimizing antibiotic prescribing by providing resources to clinicians and patients about evidence-based antibiotic prescribing, inappropriate antibiotic prescribing was persistent. The interventions used must continue to evolve and include point-of-care access to guidelines and clinical decision support tools.

BACKGROUND: Coronavirus disease (COVID-19) is a worldwide pandemic causing multiple fatalities and morbidities worldwide. We report a case of severe pneumonia causing acute respiratory distress syndrome due to a coinfection with SARS-CoV-2 and Mycobacterium abscessus in an elderly patient with multiple myeloma in Florida, USA. Case Presentation. An 84-year-old male with a medical history significant for multiple myeloma not in remission was sent to the emergency department to rule out COVID-19 infection prior to continuing his chemotherapy sessions. At presentation, he had nonspecific mild symptoms and an unremarkable physical examination. He had significant blood test findings including serum lactate dehydrogenase 373 U/L, high sensitive C-reactive protein 17.40 mg/l, and ferritin 415 ng/ml. Xpert-SARS-CoV-2 was positive. Chest radiograph revealed patchy areas of interstitial infiltrates in mid to lower lung zones. During his hospitalization course, his oxygenation deteriorated, requiring mechanical intubation. Repeat chest radiograph showed worsening bilateral infiltrates. He was started on broad-spectrum antibiotics and eventually weaned off mechanical intubation and extubated. On the 11th day of admission, he was found to be bradycardic and in shock, and he was reintubated. His labs showed worsening inflammatory markers along with kidney dysfunction to the point of requiring renal replacement therapy. He received both convalescent plasma and remdesivir for treatment of COVID-19 pneumonia. Eventually, repeat blood cultures came back positive for the growth of acid-fast beaded bacilli. While awaiting final culture and sensitivity reports, his antibiotics were upgraded to cover possible nocardia infection. Repeat blood and sputum cultures resulted in growth of AFB bacilli Mycobacterium abscessus 1 week after. CONCLUSIONS: This case report highlights the importance of keeping a broad differential and considering multiple coinfections, including atypical ones during this COVID-19 pandemic, such as the one that was discussed above, Mycobacterium abscessus, in order to provide goal-directed therapy.
RESUMO
PURPOSE: Ledipasvir/sofosbuvir is an oral combination therapy containing fixed doses of direct-acting antiviral agents indicated for the treatment of hepatitis C virus (HCV) infection. Currently there are limited data on the clinical efficacy of crushed ledipasvir/sofosbuvir administered via feeding tube. SUMMARY: This case report discusses the successful treatment of chronic HCV genotype 1b infection with crushed ledipasvir/sofosbuvir administered through a percutaneous endoscopic gastrostomy (PEG) tube in a patient with human immunodeficiency virus (HIV) coinfection and high-grade sarcoma who had severe swallowing difficulties. The patient received crushed ledipasvir/sofosbuvir daily for a total of 12 weeks. At 12 weeks the patient had achieved a sustained virologic response. CONCLUSION: Currently, ledipasvir/sofosbuvir is available only as a tablet, with limited pharmacokinetic data available to guide clinicians on use of the fixed-dose combination medication in crushed form. This case report highlights our experience treating a patient with HCV/HIV coinfection through administration of crushed ledipasvir/sofosbuvir via PEG tube, which we found to be a safe and effective therapeutic option.

ABSTRACT: Peripheral neuropathy is one of the most frequent complaints in patients with HIV. Many complex syndromes exist, with the etiology being secondary to the disease process itself, antiretroviral medication, or immune reconstitution. However, isolated mononeuropathy is rare. In this case, we present a previously healthy man who complained of several months of worsening right foot drop that did not improve with physical therapy or lifestyle interventions. He had begun to use an solid ankle-foot orthotic on this right lower limb to minimize tripping and prevent falls. He had no other neuromuscular involvement or constitutional complaints. Nerve conduction study of the right lower limb showed decreased peak amplitude, prolonged distal latency, and decreased conduction velocity of the deep peroneal nerve. Electromyography revealed abnormal insertional activity and absent motor unit action potentials in both the right tibialis anterior and right extensor digitorum brevis muscles. Magnetic resonance imaging of the right lower limb was suggestive of acute/subacute denervation of the right tibialis anterior muscle. An extensive laboratory workup revealed active HIV infection with a significant viral load. Once the diagnosis was made, the patient was started on antiretroviral treatment. Six months later, his foot drop had entirely resolved, in association with significant improvements in viral load and CD4 count. He has since been ambulating without assistive devices and his HIV/AIDS disease process remains well controlled. This clinical vignette is the first, to our knowledge, to illustrate that an acute focal mononeuropathy causing foot drop and gait dysfunction in an otherwise healthy-appearing individual can be a heralding sign of HIV/AIDS. Furthermore, it also suggests that this functional deficit can be reversed with timely initiation of antiretroviral treatment. Early recognition, diagnosis, and treatment in this patient have not only led to an uncomplicated AIDS disease course but also restored his ability to ambulate with complete independence and improved his quality of life.

BACKGROUND: First responders (FRs) may have a significant risk of coronavirus 19 (COVID-19) infection than the general population due to job-related exposures. We aimed to determine the prevalence and exposure patterns of COVID-19 among FRs. METHODS: Between March and April 2020, FRs in Broward County, Florida, were screened for COVID-19 infection by real-time reverse transcription polymerase chain reaction assay using nasopharyngeal swabs. Demographics and COVID-19 positive rate of the FRs were summarized. RESULTS: A total of 3375 FRs were screened for COVID-19 infection. The median age of FRs tested was 42 years (IQR 33-52 years), and 1464 (43.4%) were men. A total of 2902 (85.9%) were asymptomatic, and 473 (14.1%) reported symptoms associated with COVID-19. Overall, 289 (8.6%) were positive, with the highest rates among the age between 25 and 49 years. Of those testing positive, 235 (81.3%) were asymptomatic. Fourteen days after their first positive test, 81 (69.8%) of the 116 asymptomatically infected FRs were negative, and 35 (30.2%) remained positive and asymptomatic. CONCLUSIONS: The FRs in Broward County, FL, had an overall infection rate of 8.6% at the time of COVID-19 testing, and asymptomatic FRs accounted for 81.3% of infection. Active surveillance should be focused on the asymptomatic FRs with COVID-19.

Coronavirus 2 (SARS-CoV-2) is now considered a pandemic causing Coronavirus disease (COVID-19), multiple fatalities and morbidities which have been associated with it worldwide. We report a severe pneumonia causing acute respiratory distress syndrome due to a coinfection with SARS-COV-2 and Parainfluenza 4 virus in a Hispanic 21 year old male in Florida, USA. The case represents the importance of prompt diagnosis and awareness of the potential co-infection with other respiratory viruses and this novel deadly virus.
RESUMO
BACKGROUND Histoplasmosis results from the inhalation of spores from the fungus, Histoplasma capsulatum. A case is presented of pulmonary histoplasmosis associated with altered mental state and hypercalcemia following allogeneic hematopoietic stem cell transplantation for acute myeloid leukemia (AML). CASE REPORT A 75-year-old man with a five-day history of AML treated with allogeneic hematopoietic stem cell transplantation, presented with weakness, fatigue, and slow mentation. Computed tomography (CT) of the brain was unremarkable. Laboratory investigations showed serum albumin of 2.9 g/dL, calcium of 11.6 mg/dL, ionized calcium of 1.55 mmol/L, parathyroid hormone (PTH) <6.3 pg/mL, and 25-hydroxy vitamin D of 14.4 ng/mL. Treatment began with intravenous cefepime 1 gm bid, normal saline, and the bisphosphonate, pamidronate, administered as a single dose. Three days later, his clinical status declined. He developed a dry productive cough, his oxygen saturation (O2 Sat) was 90%, and his mental status worsened. Chest CT showed diffuse bilateral lung infiltrates with ground glass opacities. Bronchioalveolar lavage and transbronchial biopsy were negative for Pneumocystis jiroveci pneumonia (PJP). The CMV rival load was 195 IU/mL. Urinalysis for Histoplasma antigen and the Fungitell® assay were positive. Treatment commenced with intravenous voriconazole (250 mg, bid) and ganciclovir (5 mg/kg, bid). A left lower lobe transbronchial lung biopsy was positive for Histoplasma capsulatum and negative for CMV. CONCLUSIONS This case report has highlighted the need for awareness of the diagnosis of histoplasmosis in patients with allogeneic hematopoietic stem cell transplantation who present with an altered mental state in the setting of hypercalcemia.

Micrococcus species are typically considered contaminants from skin and mucous membranes. However, especially in severely immunocompromised patients, a blood culture with Micrococcus could be the cause of a significant infection. We report a 65-year-old female with non-Hodgkin's lymphoma who developed native valve infective endocarditis due to Micrococcus luteus. There is no defined therapeutic regimen for infective endocarditis due to Micrococcus luteus; however, our patient was successfully treated for six weeks with vancomycin and rifampin. To our knowledge, there is only one other case report of native valve endocarditis due to Micrococcus luteus.
RESUMO
BACKGROUND Ecthyma gangrenosum is an uncommon cutaneous infection commonly caused by Pseudomonas aeruginosa affecting typically immunocompromised patients. The presence of ecthyma gangrenosum can be associated with severe systemic infection often with a fatal prognosis. Most cases of ecthyma gangrenosum occur around the axilla, buttocks, and limbs; the scrotum is rarely affected. CASE REPORT A 68-year-old male with previously diagnosed acute myeloid leukemia, presented with left scrotal pain, fever, and rigors. Physical examination showed 2 ulcerating lesions with central black eschars surrounded by erythematous halos on the superior aspect of the left scrotum. Diagnosis of ecthyma gangrenosum was confirmed as both blood and lesion cultures showed growth of P. aeruginosa. After early empiric antibiotic treatment, the lesions significantly improved, and no sign of recurrence or new lesions was noticed. CONCLUSIONS Ecthyma gangrenosum should be considered in the differential diagnosis of ulcerating lesions of the scrotum. An early diagnosis and aggressive antibiotic treatment are imperative for resolution of this infection.
