Application of the RE-AIM framework to evaluate the implementation of telehealth pulmonary rehabilitation in a randomized controlled trial among African-American and Hispanic patients with advanced stage Chronic Obstructive Pulmonary Disease.

BACKGROUND: Pulmonary rehabilitation (PR) decreases rehospitalization for people with COPD. However, less than 2% receive PR, partly due to lack of referral and sparsity of PR facilities. This disparity is particularly pronounced in African American and Hispanic persons with COPD. Telehealth-provided PR could increase access and improve health outcomes. METHODS: We applied the RE-AIM framework in a post-hoc analysis of our mixed methods RCT comparing referral to Telehealth-delivered PR (TelePR) versus standard PR (SPR) for African American and Hispanic COPD patients hospitalized for COPD exacerbation. Both arms received a referral to PR for 8 weeks, social worker follow-up, and surveys administered at baseline, 8 weeks, 6, and 12 months. PR sessions were conducted twice a week for 90 min each (16 sessions total). Quantitative data were analyzed using 2-sample t tests or nonparametric Wilcoxon tests for continuous data and χ2/Fisher exact tests for categorical data. Logistic regression-estimated odds ratios (ORs) were used for the intention-to-treat primary outcome. Qualitative interviews were conducted at the end of the study to assess adherence and satisfaction and were analyzed using inductive and deductive methods. The goal was to understand Reach (whether the target population was able to be enrolled), Effectiveness (primary outcome was a composite of 6-month COPD rehospitalization and death), Adoption (proportion of people willing to initiate the program), Implementation (whether the program was able to be executed as intended, and Maintenance (whether the program was continued). RESULTS: Two hundred nine people enrolled out of a 276-recruitment goal. Only 85 completed at least one PR session 57/111 (51%) TelePR; 28/98 (28%) SPR. Referral to TelePR compared to SPR did not decrease the composite outcome of 6-month COPD-readmission rate/death (OR1.35;95%CI 0.69,2.66). There was significant reduction in fatigue (PROMIS® scale) from baseline to 8-weeks in TelePR compared to SPR (MD-1.34; ± SD4.22; p = 0.02). Participants who received TelePR experienced improvements from baseline in several outcomes (ie, before and after 8 weeks of PR) in the following: COPD symptoms, knowledge about COPD management, fatigue, and functional capacity. Among the patients who had 1 initial visit, adherence rates were similar (TelePR arm, 59% of sessions; SPR arm, 63%). No intervention-related adverse events occurred. Barriers to PR adoption included difficulty or reluctance to complete medical clearances and beliefs about PR efficacy. Notably, only 9 participants sustained exercise after program completion. Maintenance of the program was not possible due to low insurance reimbursement and sparsity of Respiratory Therapists. CONCLUSIONS: TelePR can reach COPD patients with health disparities and can be successfully implemented. The small sample size and large confidence intervals prevent conclusion about the relative effectiveness of participating in TelePR compared to SPR. However, improved outcomes were seen for those in TelePR as well as in SPR. Increasing adoption of PR and TelePR requires consideration of comorbidity burden, and perception of PR utility, and must facilitate medical clearances. Given the sparsity of SPR locations, TelePR can overcome at least the barrier of access. However, given the challenges to the uptake and completion of PR - many of the additional barriers in PR (both in TelePR and SPR) need to be addressed. Awareness of these real-world challenges will not only inform implementation of TelePR for clinicians seeking to adopt this platform but will also inform study designers and reviewers regarding the feasibility of approaches to patient recruitment and retention.

Randomized Open Investigation Determining Steroid Dose in Severe COVID-19: The ROIDS-Dose Clinical Trial.

Introduction Treatment with dexamethasone reduces mortality in patients with coronavirus disease 2019 (COVID-19) pneumonia requiring supplemental oxygen, but the optimal dose has not been determined. Objective To determine whether weight-based dexamethasone of 0.2 mg/kg is superior to 6 mg daily in reducing 28-day mortality in patients with COVID-19 and hypoxemia. Materials and methods A multicenter, open-label, randomized clinical trial was conducted between March 2021 and December 2021 at seven hospitals within Northwell Health. A total of 142 patients with confirmed COVID-19 and hypoxemia were included. Participants were randomized in a 1:1 ratio to dexamethasone 0.2 mg/kg intravenously daily (n = 70) or 6 mg daily (n = 72) for up to 10 days. Results There was no statistically significant difference in the primary outcome of 28-day all-cause mortality with deaths in 12 of 70 patients (17.14%) in the intervention group and 15 of 72 patients (20.83%) in the control group (p = 0.58). There were no statistically significant differences among the secondary outcomes. Conclusion In patients with COVID-19 and hypoxemia, the use of weight-based dexamethasone dosing was not superior to dexamethasone 6 mg in reducing all-cause mortality at 28 days. Clinical trial registration This study was registered under ClinicalTrials.gov (identifier: NCT04834375).

Attenuation of Human Growth Hormone-Induced Rash With Graded Dose Challenge.

Adult growth hormone (GH) deficiency is rare and requires replacement with extrinsic/synthetic injection. GH hypersensitivity has been reported; specifically, atopic patients may develop rashes from somatotropin therapy. Allergic and non-allergic skin reactions to recombinant human GH are uncommon and infrequently reported. We describe a graded-dose challenge with intravenous Norditropin® in a 65-year-old atopic adult woman who developed a severe whole-body rash with Norditropin FlexPro® administration on several occasions but was negative on skin-prick testing to Norditropin® percutaneously and intradermally, but the patch testing was positive for gold and nickel. The patient was registered as a direct admission to the emergency room at a university hospital for a rapid antigen coronavirus disease 2019 (COVID-19) testing after having received two COVID-19 vaccinations and re-testing four months after vaccination. She was then directly admitted to a non-COVID-19 intensive care unit with direct bedside supervision by a registered nurse and a physician board certified in internal medicine, allergy/immunology, and pulmonary diseases. The patient brought a Norditropin® pen which our pharmacy team attached to a compatible syringe for dilutions. A graded dose challenge at a final dosage of 0.1 mL was performed and the patient was monitored for allergic and other adverse drug reactions, which did not occur. At the time of writing this case report, the patient has been maintained on Norditropin FlexPro® 0.1 mL and has not experienced any adverse reactions, including recurrent skin eruptions. The case presented is the first to describe a patient who successfully tolerated a graded dose challenge of an adult patient to GH replacement therapy (as Norditropin®) under supervision in an intensive care unit, whereas prior to reporting of this case, a graded dose challenge to GH replacement therapy had only been successfully performed in a child using another formulation of somatotropin (Humatrope®). Hence, this case lends support that graded dose challenge with somatotropin analogs may be considered for patients with isolated GH deficiency such as in the case presented here.

Efficacy and Safety of Therapeutic-Dose Heparin vs Standard Prophylactic or Intermediate-Dose Heparins for Thromboprophylaxis in High-risk Hospitalized Patients With COVID-19: The HEP-COVID Randomized Clinical Trial.

Importance: Hospitalized patients with COVID-19 are at risk for venous and arterial thromboembolism and death. Optimal thromboprophylaxis dosing in high-risk patients is unknown. Objective: To evaluate the effects of therapeutic-dose low-molecular-weight heparin (LMWH) vs institutional standard prophylactic or intermediate-dose heparins for thromboprophylaxis in high-risk hospitalized patients with COVID-19. Design, Setting, and Participants: The HEP-COVID multicenter randomized clinical trial recruited hospitalized adult patients with COVID-19 with D-dimer levels more than 4 times the upper limit of normal or sepsis-induced coagulopathy score of 4 or greater from May 8, 2020, through May 14, 2021, at 12 academic centers in the US. Interventions: Patients were randomized to institutional standard prophylactic or intermediate-dose LMWH or unfractionated heparin vs therapeutic-dose enoxaparin, 1 mg/kg subcutaneous, twice daily if creatinine clearance was 30 mL/min/1.73 m2 or greater (0.5 mg/kg twice daily if creatinine clearance was 15-29 mL/min/1.73 m2) throughout hospitalization. Patients were stratified at the time of randomization based on intensive care unit (ICU) or non-ICU status. Main Outcomes and Measures: The primary efficacy outcome was venous thromboembolism (VTE), arterial thromboembolism (ATE), or death from any cause, and the principal safety outcome was major bleeding at 30 ± 2 days. Data were collected and adjudicated locally by blinded investigators via imaging, laboratory, and health record data. Results: Of 257 patients randomized, 253 were included in the analysis (mean [SD] age, 66.7 [14.0] years; men, 136 [53.8%]; women, 117 [46.2%]); 249 patients (98.4%) met inclusion criteria based on D-dimer elevation and 83 patients (32.8%) were stratified as ICU-level care. There were 124 patients (49%) in the standard-dose vs 129 patients (51%) in the therapeutic-dose group. The primary efficacy outcome was met in 52 of 124 patients (41.9%) (28.2% VTE, 3.2% ATE, 25.0% death) with standard-dose heparins vs 37 of 129 patients (28.7%) (11.7% VTE, 3.2% ATE, 19.4% death) with therapeutic-dose LMWH (relative risk [RR], 0.68; 95% CI, 0.49-0.96; P = .03), including a reduction in thromboembolism (29.0% vs 10.9%; RR, 0.37; 95% CI, 0.21-0.66; P < .001). The incidence of major bleeding was 1.6% with standard-dose vs 4.7% with therapeutic-dose heparins (RR, 2.88; 95% CI, 0.59-14.02; P = .17). The primary efficacy outcome was reduced in non-ICU patients (36.1% vs 16.7%; RR, 0.46; 95% CI, 0.27-0.81; P = .004) but not ICU patients (55.3% vs 51.1%; RR, 0.92; 95% CI, 0.62-1.39; P = .71). Conclusions and Relevance: In this randomized clinical trial, therapeutic-dose LMWH reduced major thromboembolism and death compared with institutional standard heparin thromboprophylaxis among inpatients with COVID-19 with very elevated D-dimer levels. The treatment effect was not seen in ICU patients. Trial Registration: ClinicalTrials.gov Identifier: NCT04401293.

Pulmonary Function Testing in Patients With E-Cigarette, or Vaping, Product Use-Associated Lung Injury.

In 2019 there was an outbreak of respiratory illnesses amongst people who used E-cigarettes. This phenomenon was labeled 'EVALI' which stands for "Electronic cigarette (E-cigarette), or Vaping, Product Use-Associated Lung Injury" and is a life-threatening illness of the lungs associated with E-cigarette use. It is believed to be caused by certain chemicals in E-cigarette cartridges, such as vitamin E acetate, but the exact pathophysiological mechanism is yet to be elucidated. Since 2019, the CDC has recorded over 2800 cases in the United States with over 60 deaths. Though many people recover from EVALI, the long-term implications on pulmonary health are unknown. The purpose of this retrospective study was to demonstrate the pulmonary function test (PFT) findings in a group of patients who recovered from a diagnosis of EVALI. We reviewed the cases of 23 adult patients who presented to two major academic hospitals of the Northwell Health System with confirmed EVALI and followed up in our outpatient clinics with PFTs. Most patients had significantly reduced diffusion capacity (DLCO) demonstrating loss of functioning alveolar units. Given that average follow-up was over a month after discharge, this leads us to believe that EVALI can lead to persistent lung damage. However, further follow-up would be necessary to identify the full impact of E-cigarette use on the pulmonary function.

Treatment-Dose LMWH versus Prophylactic/Intermediate Dose Heparins in High-Risk COVID-19 Inpatients: Rationale and Design of the HEP-COVID Trial.

Coronavirus disease-2019 (COVID-19) has been associated with significant risk of venous thromboembolism (VTE), arterial thromboembolism (ATE), and mortality particularly among hospitalized patients with critical illness and elevated D-dimer (Dd) levels. Conflicting data have yet to elucidate optimal thromboprophylaxis dosing. HEP-COVID (NCT04401293) is a phase 3, multicenter, pragmatic, prospective, randomized, pseudo-blinded, active control trial to evaluate efficacy and safety of therapeutic-dose low-molecular-weight heparin (LMWH) versus prophylactic-/intermediate-dose LMWH or unfractionated heparin (UFH) for prevention of a primary efficacy composite outcome of VTE, ATE, and all-cause mortality 30 ± 2 days post-enrollment. Eligible patients have COVID-19 diagnosis by nasal swab or serologic testing, requirement for supplemental oxygen per investigator judgment, and Dd >4 × upper limit of normal (ULN) or sepsis-induced coagulopathy score ≥4. Subjects are randomized to enoxaparin 1 mg/kg subcutaneous (SQ)/two times a day (BID) (creatinine clearance [CrCl] ≥ 30 mL/min) or 0.5 mg/kg (CrCl 15-30 mL/min) versus local institutional prophylactic regimens including (1) UFH up to 22,500 IU (international unit) daily (divided BID or three times a day), (2) enoxaparin 30 and 40 mg SQ QD (once daily) or BID, or (3) dalteparin 2,500 IU or 5,000 IU QD. The principal safety outcome is major bleeding. Events are adjudicated locally. Based on expected 40% relative risk reduction with treatment-dose compared with prophylactic-dose prophylaxis, 308 subjects will be enrolled (assuming 20% drop-out) to achieve 80% power. Distinguishing design features include an enriched population for the composite endpoint anchored on Dd >4 × ULN, stratification by intensive care unit (ICU) versus non-ICU, and the ability to capture asymptomatic proximal deep venous thrombosis via screening ultrasonography prior to discharge.

Pneumatosis Intestinalis in COVID-19: Case Series.

OBJECTIVE: To describe the clinical characteristics and outcomes of patients with coronavirus disease 2019 (COVID-19) who developed pneumatosis intestinalis (PI). METHODS: This case series was conducted in intensive care units at two large tertiary care centers within the Northwell Health System, located in New York State. Patients were included if they were identified as having confirmed COVID-19 as well as pneumatosis intestinalis from March 16, 2020 to July 31, 2020. Patient demographics, clinical characteristics, vasopressor use, anticoagulation use, opiate use, paralytic use, COVID-19 treatment regimen, serum lactate, arterial pH, serum bicarbonate, subsequent intervention, and outcomes during hospitalization were collected.  Results: A total of nine patients were identified. Average serum lactate was 4.33 mmol/L at time of diagnosis. Portal venous gas (56%) and bowel dilation (56%) were common radiographic findings. Subsequent morbidity (increased vasopressor requirements - 67%, acute kidney injury - 67%, increased oxygen requirements - 44%) and mortality (78%) were high. PI occurred despite a majority of patients being on anticoagulation (78%). Interleukin-6 (IL-6) inhibitors were commonly administered (56%) prior to development of PI. CONCLUSION: Pneumatosis intestinalis in COVID-19 is clinically significant, with high morbidity and mortality, and is also likely underdiagnosed.

Acute Respiratory Failure Associated With Vaping.

The use of e-cigarettes to deliver aerosolized nicotine has gained popularity in recent years. Numerous reports have cited the development of acute pulmonary disease linked to vaping nicotine as well as marijuana-based products. As cultural attitudes evolve and policies shift toward the legalization of marijuana, its use has become more prevalent. Given the increased prevalence of marijuana consumption and e-cigarette usage, better insight into its potential to cause lung toxicity is warranted. The clinical, radiographic, and histopathologic characteristics of lung injury associated with vaping, particularly with marijuana-based products, have yet to be well described in the literature. We present eight patients, most of whom were admitted recently to our institution with acute respiratory failure following vaping. The majority of patients were young, with a median age of 31.5 years (range, 24-62 years) and with no known underlying lung disease. This case series highlights common clinical findings as well as the varied radiographic and histopathologic features of acute respiratory failure associated with vaping predominantly marijuana-based products. As more cases of vaping-associated pulmonary injury unfold, data will be available to further characterize this emerging disease entity. Improved understanding of disease pathogenesis and its clinical course will help clinicians determine optimal management and follow-up strategies for this patient population.

Pneumothorax in COVID-19 Acute Respiratory Distress Syndrome: Case Series.

Objective The study aims to describe the clinical characteristics and outcomes of patients with COVID-19 related acute respiratory distress syndrome (ARDS) who developed pneumothorax. Design and setting A retrospective chart review was performed of the electronic medical record. Patients were included if they were identified as having confirmed COVID-19 as well as pneumothorax from March 16, 2020 to May 31, 2020. Patients' demographic and clinical characteristics, mechanical ventilator parameters, lung compliance measurements and outcomes during hospitalization were collected. This case series was conducted in intensive care units at two large tertiary care centers within the Northwell Health System, located in New York State. Patients A total of 75 patients were identified who were predominantly male (73.3%) with an average age of 62.8 years. Thirty (40%) were Hispanic, 20 (26.7%) were White, 16 (21.3%) were Asian, and nine (12%) were Black. Common comorbid conditions were hypertension (52%), diabetes mellitus (26.7%), hyperlipidemia (32.0%), and chronic pulmonary disease (8, 10.7%). Measurements and main results Most of the patients were diagnosed with pneumothorax while on mechanical ventilation (92%) despite overall adherence with lung-protective ventilation strategies. Average tidal volume was 6.66 mL/kg) of ideal body weight. The average positive end-expiratory pressure (PEEP) was 10.83 (cm) H2O. Lung compliance was poor, with average peak and plateau pressures of 41.9 cm H2O and 35.2 cm H2O, respectively. Inpatient mortality was high in these patients (76%). Conservative management with initial observation had a success rate (73.3%) with similar mortality and shorter length of stay (LOS) on average. Significant factors in the conservatively managed group included lack of tension physiology, the smaller size of pneumothorax, lack of underlying diabetes, presence of pneumomediastinum, and not being on mechanical ventilation during diagnosis. Conclusion Despite overall adherence to best practice ventilator management in ARDS, we observed a large number of pneumothoraces during the COVID-19 pandemic. Conservative management may be appropriate if there are no clinical signs or symptoms of tension physiology and pneumothorax size is small.

Acute Opiate Overdose: An Update on Management Strategies in Emergency Department and Critical Care Unit.

BACKGROUND: Opioids are natural, semisynthetic, or synthetic substances that act on opioid receptors in the central nervous system. Clinically, they are prescribed for pain management. Opioid overdose (OOD) occurs when the central nervous system and respiratory drive are suppressed because of excessive consumption of the drug. Symptoms of OOD include drowsiness, slow breathing, pinpoint pupils, cyanosis, loss of consciousness, and death. Due to their addictive potential and easy accessibility opioid addiction is a growing problem worldwide. Emergency medical services and the emergency department often perform initial management of OOD. Thereafter, some patients require intensive care management because of respiratory failure, metabolic encephalopathy, acute kidney injury, and other organ failure. AREAS OF UNCERTAINTY: We sought to review the literature and present the most up-to-date treatment strategies of patients with acute OOD requiring critical care management. DATA SOURCES: A PubMed search was conducted to review all articles between 1950 and 2017 and the relevant articles were cited. RESULTS & CONCLUSIONS: Worldwide, approximately 69,000 people die of OOD each year, and approximately 15 million people have opioid addiction. In the United States, death from OOD has increased almost 5-fold from 2001 to 2013. OOD leading to intensive care unit admission has increased by 50% from 2009 to 2015. At the same time, the mortality associated with these admissions has doubled. The management strategies include airway management, use of reversal agents, assessing and treating coingestions and associated complications, treatment of opioid withdrawal with alpha-agonists, and psychosocial support to help with opiate addiction and withdrawal. This warrants awareness among clinicians regarding the adverse effects associated with opioid use, management strategies, and calls for a multidisciplinary approach to treating these patients.

Pathologic Findings in Bronchopulmonary Leukemic Infiltrates in Patients With Chronic Lymphocytic Leukemia.

INTRODUCTION: Chronic lymphocytic leukemia (CLL) is the most common lymphoproliferative disorder worldwide. Although thoracic complications are frequent in CLL, only limited data exists regarding these complications. Pleural, parenchymal, and airway disease may occur owing to CLL itself, treatment-related adverse events, typical or opportunistic infections, or from preexisting comorbidities. The etiology of parenchymal infiltrates is often attributed to pneumonia and can be difficult to properly identify without a diagnostic procedure. PATIENTS AND METHODS: We conducted a retrospective chart review of patients admitted from 2000 through 2016 with a diagnosis of CLL and abnormal radiography that underwent a bronchoscopy with biopsy, surgical lung biopsy, or transthoracic biopsies for nonresolving infiltrates after a course of antibiotics. We described the incidence of bronchopulmonary leukemic infiltrates (BPLI), describe other diagnosis achieved by the biopsy, and also describe the pathologic findings associated with BPLI in these patients. RESULTS: There were 111 procedures performed on 98 patients that yielded a diagnosis in 82 patients. In 16 patients, no histologic or pathologic diagnosis was identified after the biopsy. BPLI was diagnosed in 32 (39%) cases. In 27 (85%) of 32 cases, the biopsies returned with only BPLI owing to CLL (without inflammation), whereas 5 (15%) of 32 cases showed concomitant acute or chronic inflammation. CONCLUSION: Direct infiltration by leukemic cells may cause pulmonary symptoms and signs indistinguishable from infection. Biopsy is necessary to establish a definitive diagnosis, and physicians caring for these patients, including pathologists, should be aware of the clinicopathologic picture of BPLI to render an informative diagnosis.

Chylothorax in Patients with Chronic Lymphocytic Leukemia: A Case Series.

Chylothorax, which is defined as the presence of chyle in the pleural space, is often caused by malignancy. However, chylothorax as a result of underlying CLL is exceedingly rare in the literature. Chyle contains fat soluble vitamins and lymphocytes, meaning that its collection into the pleural space may further exacerbate the immunosupressed state of an individual with CLL. Here, we report three cases of patients with CLL who developed chylothorax, and their management. Chylothorax, although rare with CLL, should be considered in the differential diagnosis when patients with CLL present with pleural effusions, especially if recurrent. Discovery of a chylothorax may indicate the need for further treatment of CLL.

A 68-Year-Old Man With Dyspnea on Exertion and Cough.

A 68-year-old man with a history of chronic lymphocytic leukemia well controlled on ibrutinib, hypertension, obesity, and a remote history of smoking (10 pack-years) presented with increasing dyspnea on exertion and cough. He had previously finished two courses of oral antibiotics for his symptoms without significant improvement. On presentation, he had no fevers or sputum production.

A case of hepatic tuberculosis: A tuberculoma.

Tuberculosis (TB) is a common cause of morbidity and mortality worldwide and its eradication in the United States has stalled for the first time in decades. Isolated hepatic TB is an extremely uncommon form of extrapulmonary TB. Here we present a case of a tuberculous liver abscess and suggest that TB should be considered in patients who fail to respond to antibiotics and prompt diagnostic intervention.

Pulmonary hypertension associated with antiphospholipid antibody: Call for a screening tool?

Antiphospholipid (aPL) antibodies are antibodies specific for anionic phospholipids. They are immunoglobulins that attack phospholipids, phospholipid-binding proteins, or phospholipid-protein complexes and are detected in anticardiolipin and lupus anticoagulant assays. aPL antibodies are often associated with antiphospholipid syndrome (APS) which can be idiopathic or from secondary causes such as systemic lupus erythematosus (SLE), infection or drugs. They have also been shown to be associated with Pulmonary Hypertension. We conducted a review of the literature that included all articles on PubMed with keywords 'antiphospholipid antibody' and 'pulmonary hypertension' between January 1980 and July 2017 and identified 217 articles. A total of 47 articles were found to be relevant to the topic and included as references. We ascertained that aPL antibodies have been implicated in the development of both idiopathic pulmonary arterial hypertension (PAH) and PAH associated with connective tissue disease (CTD). aPL antibodies were also noted to be associated with left-sided valvular heart disease that can lead to pulmonary venous hypertension (PVH). Patients with anitiphospholipid antibody syndrome (Diagnostic criteria incudes +aPL antibodies) were noted to have a high risk of developing chronic thromboembolic pulmonary hypertension (CTEPH). A recent study also found a positive association of aPL antibodies with ILD and PH in patients with systemic sclerosis. While association between autoimmune thyroid disease and PH (Group V PH), and autoimmune thyroid disease and aPL antibodies is established, no studies linked these three phenomena together. Thus, aPL antibodies had an association with all WHO groups of Pulmonary hypertension (PH). In this review article, we study the association and discuss the need for screening for PH in patients with positive aPL antibodies.

Socioeconomic status and its relationship to chronic respiratory disease.

Socioeconomic status (SES) is defined as an individual's social or economic standing, and is a measure of an individual's or family's social or economic position or rank in a social group. It is a composite of several measures including income, education, occupation, location of residence or housing. Studies have found a lower SES has been linked to disproportionate access to health care in many diseases. There is emerging data in pulmonary diseases such as COPD, asthma, cystic fibrosis, pulmonary hypertension and other chronic respiratory conditions that allude to a similar observation noted in other chronic diseases. In the setting of COPD, SES has an inverse relationship with COPD prevalence, mortality, health utilization costs and HRQoL. Asthma and cystic fibrosis show an increased severity and hospitalizations in relationship to a lower SES. Similar observations were seen in sarcoidosis, PHTN and obstructive sleep apnea. There remains a limited data on non-CF bronchiectasis and interstitial lung diseases. Population SES may be gauged by various measures such as education, occupation, marital status but no value is more indicative than income. Currently guidelines and management algorithms do not factor the effect of SES in the disease process. Despite the great amount of data available, a standardized method must be created to include SES in the prognostic calculations and management of chronic pulmonary diseases.

Thoracic Complications in Chronic Lymphocytic Leukemia.

BACKGROUND: Chronic lymphocytic leukemia (CLL) is the most common lymphoproliferative disorder worldwide. Although thoracic complications are frequent in CLL, only limited data exist regarding the etiologies of these complications. MATERIALS AND METHODS: A retrospective chart review was performed on all patients admitted to a tertiary care, CLL referral center, with CLL and a respiratory complaint from 2001 through 2013, to categorize pulmonary complaints and diagnoses. RESULTS: There were 277 patients with CLL admitted on 409 occasions with respiratory complaints. The median age was 73 years, with a male to female ratio of 2:1. The majority of patients had a high-risk Rai classification and had received prior treatment. Common presenting symptoms included dyspnea, cough, and sputum production. The most common diagnoses were pneumonia (62.8%), with an identified organism in 44.7%, pleural effusions (31.8%), lung cancer (6.9%), and leukemic infiltrates (5.9%). Invasive procedures were performed 138 times: 70 bronchoscopies, 24 surgical lung biopsies, 10 computed tomography-guided lung biopsies, and 34 thoracenteses. In-hospital mortality was 24.9%. In a multivariable analysis, an elevated blood urea nitrogen level and creatinine, thrombocytopenia, and a presenting symptom of dyspnea correlated significantly with in-hospital mortality. CONCLUSION: Thoracic manifestations in CLL are common among hospitalized patients. Although infectious pneumonia remains most common, unusual or opportunistic infections may be increasing, and direct lung damage owing to CLL itself or to newer biologic agents are being diagnosed with lung tissue sampling. Recognition of these complications will allow earlier diagnosis, which may change management including removal of offending biologic agents or augmentation of treatment for CLL when infiltrative leukemic cells are present.
