Ortner syndrome as a presenting symptom of severe chronic mitral regurgitation in heart failure: A case report [Case Report]

Song, David; Bayshtok, Sabina; Shah, Vaibhav; Jaiswal, Vikash; Seo, Angie; Rubinstein, David
Ortner's syndrome or cardiovocal syndrome is a clinical condition associated with hoarseness due to left recurrent laryngeal nerve palsy from compression of surrounding cardiovascular structures. Atrial enlargement, commonly caused by chronic mitral regurgitation (MR) may be a source of compression. We present a case of a 53-year-old man with decompensated heart failure (HF) with a new onset of hoarseness. Chest radiograph showed cardiomegaly with evidence of fluid overload; transthoracic echocardiography showed bi-atrial enlargement secondary to severe chronic mitral regurgitation and moderate pulmonary hypertension. As a result, the diagnosis of Ortner's syndrome was made. For patients with new onset hoarseness with a history of severe cardiovascular disease, Ortner's syndrome should be considered and early initiation of therapy can help reduce the incidence.

AIMS:Pre-existing cardiovascular disease in general and related risk factors have been associated with poor coronavirus disease-2019 (COVID-19) outcomes. However, data on outcomes of COVID-19 among people with pre-existing diagnosis of heart failure (HF) have not been studied in sufficient detail. We aimed to perform detailed characterization of the association of pre-existing HF with COVID-19 outcomes. METHODS AND RESULTS:A retrospective cohort study based on Veterans Health Administration (VHA) data comparing 30 day mortality and hospital admission rates after COVID-19 diagnosis among Veterans with and without pre-existing diagnosis of HF. Cox-regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (95% CIs) with adjustment for covariates. Among 31 051 veterans (97% male) with COVID-19, 6148 had pre-existing diagnosis of HF. The mean (SD) age of patients with HF was 70 (13) whereas the mean (SD) age of patients without HF was 57 (17). Within the HF group with available data on left ventricular ejection fraction (EF), 1844 patients (63.4%) had an EF of >45%, and 1063 patients (36.6%) had an EF of ≤45%. Patients in the HF cohort had higher 30 day mortality (5.4% vs. 1.5%) and admission (18.5% vs. 8.4%) rates after diagnosis of COVID-19. After adjustment for age, sex, and race, HRs (95% CIs) for 30 day mortality and for 30 day hospital admissions were 1.87 (1.61-2.17) and 1.79 (1.66-1.93), respectively. After additional adjustment for medical comorbidities, HRs for 30 day mortality and for 30 day hospital admissions were 1.37 (1.15-1.64) and 1.27 (1.16-1.38), respectively. The findings were similar among HF patients with preserved vs. reduced EF, among those taking vs. not taking angiotensin-converting enzyme inhibitors, angiotensin receptor blockers or angiotensin receptor neprilysin inhibitors, and among those taking vs. not taking anticoagulants. CONCLUSIONS:Patients with COVID-19 and pre-existing diagnosis of HF had a higher risk of 30 day mortality and hospital admissions compared to those without history of HF. The findings were similar by EF categories and by angiotensin-converting enzyme inhibitors/angiotensin receptor blocker/angiotensin receptor neprilysin inhibitors or anticoagulant use.

Hyperammonemia syndrome due to Ureaplasma urealyticum in a kidney transplant recipient: A case of disseminated disease from a fluoroquinolone-resistant isolate [Case Report]

Higgins, Andrea B; Farmakiotis, Dimitrios; Rogers, Ralph; Osband, Adena J; Seo, Angie; Chen, Brendan; Birkenbach, Mark P; Crabb, Donna; Xiao, Li; Leal, Sixto; Waites, Ken; Gohh, Reginald; Morrissey, Paul; Nau, Gerard J
Ureaplasma species (spp.) are common colonizers of the urogenital tract but may cause systemic infection in immunocompromised patients. They release significant amounts of ammonia via urea hydrolysis and have been recently implicated in the pathogenesis of hyperammonemia syndrome after organ transplantation. We describe a unique case of hyperammonemia syndrome after kidney transplant caused by U urealyticum infection, and the first, to our knowledge, case of a fluoroquinolone-resistant Ureaplasma strain causing hyperammonemia syndrome. A 17-year-old female developed intermittent fevers, rising creatinine, sterile pyuria and debilitating polyarthritis approximately 1 year after kidney transplant. Serum ammonia level was elevated, and urine PCR was positive for U urealyticum. Near the end of treatment with levofloxacin, she had rebound hyperammonemia, which preceded clinical relapse of polyarthritis and encephalopathy. Blood and urine PCR and synovial fluid culture were positive for U urealyticum. Susceptibility testing showed fluoroquinolone resistance, but she responded well to azithromycin and doxycycline. The frequency of Ureaplasma spp. infection in immunocompromised patients is probably underestimated due to diagnostic challenges. Ammonia levels were helpful biomarkers of response to antimicrobial therapy in our case. Susceptibility testing of clinical isolates should be pursued. In serious Ureaplasma spp. infections, particularly in immunocompromised patients, two empiric antibiotics may be indicated given the potential for antimicrobial resistance.
