Hydralazine is a vasodilator used for the management of hypertension, heart failure, and hypertensive emergencies in pregnancy. It has been implicated in the causation of drug-induced lupus erythematosus (DLE) and rarely with ANCA-associated vasculitis (AAV), which may present as a pulmonary-renal syndrome and be rapidly fatal. Herein, we describe a case of hydralazine-associated AAV presenting as acute kidney injury with the use of early bronchoalveolar lavage (BAL) with serial aliquots to aid with diagnosis. Our case highlights how, in the correct clinical setting, BAL can act as a rapid diagnostic test to help guide quicker treatment to allow for better patient outcomes.

Objectives Palliative Medicine involvement in MICU patients have improved length of stay and mortality, but with varying effects on specific patient decision outcomes, such as, advance care planning. These studies have utilized Palliative Medicine later in the hospital or ICU course, with some evidence showing that earlier involvement resulted in better results. The purpose of this study was to evaluate the benefits of early (within 24 hours) palliative care consultation in medical ICU (MICU) patients to clinical and satisfaction outcomes. Methods An unblinded randomized study performed in the MICU in one academic hospital in the USA. Ninety-one adult patients admitted to MICU received a Palliative care medicine consultation within 24 hours as the intervention. Measurements and results Ninety-one patients admitted to the MICU underwent randomization with 50 patients randomly assigned to receive Palliative Medicine consultation and 41 patients randomly assigned to receive standard-of-care based on predefined criteria. The median satisfaction score was 23 points higher for the patients in the intervention group (P < .001). The median length of MICU stay was 5 days shorter in the intervention group compared to the control group (95% CI; 1 day to 18 days, P = .018). Advance care planning was completed in the hospital for 34% of patients in the intervention arm and 12% of patients in the controls arm (absolute risk difference 22%, 95% CI 4% to 37%, P = .016). Conclusion Early Palliative Medicine consultation within 24 hours of MICU admission showed significant benefits to patients by improving satisfaction and decreasing length of stay. This study provides evidence that Palliative Medicine involvement earlier in the course of severe disease is important. Further studies in other types of intensive care units (neurological and Cardiovascular) are necessary to determine their impact.

Once patients are diagnosed with pulmonary hypertension it is important to identify the correct diagnostic group as it will have implications on the disease state management. Pulmonary hypertension is increasingly diagnosed and treated in general medical practices; however, evidence-based guidelines recommend evaluation and treatment in pulmonary hypertension centers for accurate diagnosis and appropriate treatment recommendations. We conducted a retrospective cohort study of 509 random patients 18 years and older who were evaluated in our pulmonary hypertension clinic from January 2005 to December 2018. 68.4% (n = 348) had their diagnostic group clarified or changed. Pulmonary hypertension was deemed an incorrect diagnosis in 12.4% (n = 63). A total of 114 patients (22.4%) had been initiated on pulmonary hypertension specific treatment prior to presentation. Pulmonary hypertension specific medication was stopped in 57 (50.0%) cases. The estimated monthly saving of the stopped medication based on wholesale acquisition costs was USD 396,988.05–419,641.05, a monthly saving of USD 6964.70–7362.12 per patient. Evaluation outside of a pulmonary hypertension center may lead to misdiagnosis and inappropriate or inadequate treatment. Pulmonary arterial hypertension directed therapy improves median survival, but inappropriate therapy may cause harm; therefore, patients benefit from a specialized center with multiple resources to secure an accurate diagnosis and tailored treatment for their condition.

Pulmonary arterial hypertension (PAH) is a devastating disease with significant morbidity and mortality. There are many psychosocial and financial implications of this disease; however, little is known how this affects the treatment of PAH patients. A questionnaire-based prospective cohort study was performed on 106 PAH patients from a Pulmonary Hypertension Center and the Pulmonary Hypertension Association national conference in 2018. The demographic, treatment, psychosocial, employment, financial impact on treatment data was obtained. The majority of patients had cardiopulmonary symptoms despite treatment. The symptoms affected their social and work lives, with about one in three applying for disability because of their PAH. The majority of PAH patients had insurance coverage, but still noted a significant financial burden of the disease, with nearly a half who needed financial assistance to pay for their PAH medications. Thirty (28.3%; 95% CI, 20.6–37.5%) patients mentioned they changed their medication regimen, with some skipping doses outright (28 [26.4%; 95% CI, 19–35.6%]) in order to save money. PAH continues to cause significant psychosocial and financial burden on patients despite advances in medications. This impact ranged from dissatisfaction with quality of life, to unemployment, to altering their medication regimen to save money.

Pulmonary arterial hypertension (PAH) is a progressive disease that requires validated biomarkers of disease severity. While PAH is defined hemodynamically by right heart catheterization (RHC), brain natriuretic peptide (BNP) is recommended by guidelines to assess disease status. Retrospectively collected data in 138 group 1 PAH patients were examined for the correlation of BNP levels to simultaneously obtained right heart catheterization (RHC). Patients were mostly Caucasian women, with functional class III symptoms, mean BNP of 406 ± 443 pg/mL, and an average right atrial pressure (RAP) of 9.9 ± 5.7 mm Hg and mean pulmonary artery pressure (mPAP) of 47.3 ± 14.7 mm Hg. Significant correlation was demonstrated between BNP and RAP (p = 0.021) and mPAP (p = 0.003). Additional correlation was seen with right heart size on echocardiography: right atrial (RAE; p = 0.04) and right ventricular enlargement (p = 0.03). An increased BNP level was an independent predictor of mortality (p < 0.0001), along with RAP (p = 0.039) and RAE (p = 0.018). Simultaneous collection of BNP at the time of RHC confirmed the correlation of BNP with right heart hemodynamics. The current results reinforce the use of BNP level as a continuous variable to assess disease severity in group 1 PAH.
