Echocardiographic Differences in Women Across Subtypes of Hypertensive Disorders of Pregnancy.

Background: Hypertensive disorders of pregnancy (HDP) can be classified into gestational hypertension, preeclampsia (PRE), and chronic hypertension with superimposed preeclampsia (SPE). Objectives: The purpose of this study was to retrospectively examine the echocardiographic differences in biventricular structure and function in 3 HDP groups of women in comparison to normotensive pregnant controls. Methods: Women with an echocardiogram during or within the first year of pregnancy were identified within our integrated health network. Exclusion criteria included age <18 years, diagnosis of pulmonary embolism, malignancy, autoimmune disease, and structural heart disease. Results: We identified a total of 706 subjects (cases: n = 427, normotensive controls: n = 279). Cases were divided into 3 groups: gestational hypertension (n = 57), PRE (n = 291), and SPE (n = 79). In adjusted analyses, echocardiographic parameters demonstrated a graded difference in left ventricular (LV) mass index, relative wall thickness, mitral inflow E, mitral inflow A, septal e', lateral e', E/e', left atrial volume index, tricuspid velocity, and lateral e' velocities with the most profound findings noted in the SPE group. Specifically, adjusted LV mass index (adjusted ß = 14.45, 95% CI: 9.00-19.90) and E/e' (adjusted ß = 2.97, 95% CI: 2.27-3.68) was highest in the SPE group in comparison to controls (P < 0.001). Conclusions: LV remodeling and diastolic filling abnormalities are more common in HDP and are most evident in SPE and PRE. Echocardiography during or immediately after pregnancy may be useful in these high-risk women to identify these abnormalities. The long-term implications of these echocardiographic abnormalities require further study.

Propitious temporal changes in clinical outcomes after transcatheter compared to surgical aortic valve replacement; a meta-analysis of over 65,000 patients.

BACKGROUND: The treatment of symptomatic severe aortic stenosis (AS) has rapidly evolved over the past decade, in both transcatheter (TAVR) and surgical aortic valve replacement (SAVR), resulting in reported improved clinical outcomes. Operator experience and technical improvements have improved outcomes especially for patients undergoing TAVR. We sought to determine and compare 1-year outcomes using a contemporary meta-analysis. METHOD: We searched the Medline (MESH), Cochrane and Google scholar databases using keywords "AS", "atrial fibrillation" (AFib) and "stroke". We performed a meta-analysis to compare TAVR with SAVR populations for post-procedural stroke, all-cause and cardiovascular mortality at 1-year. RESULTS: A total of 23 studies met criteria for analysis with total population of 66,857 patients, of which 61,913 had TAVR and 4944 had SAVR. Temporal trends demonstrated overall improvement in outcome for both, TAVR and SAVR groups through the decade. Outcomes, in terms of stroke (3.1% vs. 5%), all-cause (12.4% vs. 10.3%) and cardiovascular mortality (7.2% vs. 6.2%) were similar at 1-year, in TAVR versus SAVR, respectively. CONCLUSION: Despite overall gradual improvement in both TAVR and SAVR outcomes over the decade, there is a statistical overlap in confidence intervals for all-cause, cardiovascular mortality and postprocedural stroke at 1-year. While 23 individual studies demonstrate considerable advantages of each technique in certain cohorts, integrating over 65,000 pts with our stratified surgical analysis suggests that TAVR is comparable to SAVR for low and intermediate risk population while superior to SAVR only in the highest-risk population for short and intermediate term outcomes. This has substantial socio-economic implications as we contemplate expanding our TAVR indications to low/intermediate risk populations.

Breakthrough Mucormycosis Developing on Mucorales-Active Antifungals Portrays a Poor Prognosis in Patients with Hematologic Cancer.

Although breakthrough mucormycosis (BT-MCR) is known to develop on mold-active antifungals without Mucorales activity, it can also occur while on Mucorales-active antifungals. Herein, we retrospectively compared the characteristics and outcomes of patients with hematologic malignancies (HMs) or hematopoietic stem cell transplant (HSCT) who developed BT-MCR on mold-active antifungals with or without Mucorales activity. Of the patients developing BT-MCR, 16 were on Mucorales-active antifungals (9 isavuconazole, 6 posaconazole, 1 amphotericin B), and 87 were on other mold-active agents (52 voriconazole, 22 echinocandins, 8 itraconazole, 5 echinocandin + voriconazole). Both groups were largely comparable in clinical characteristics. Patients developing BT-MCR while on Mucorales-active antifungals had higher 42-day mortality, from either symptom onset (63% versus 25%, p = 0.006) or treatment initiation (69% versus 39%, p = 0.028). In multivariate Cox regression analysis, exposure to Mucorales-active antifungals prior to BT-MCR had a hazard ratio of 2.40 (p = 0.015) for 42-day mortality from treatment initiation and 4.63 (p < 0.001) for 42-day mortality from symptom onset. Intensive care unit (ICU) admission and APACHE II score at diagnosis, non-recovered severe neutropenia, active HM, and amphotericin B/caspofungin combination treatment were additional independent predictors of 42-day mortality. In summary, BT-MCR on Mucorales-active antifungals portrays poor prognosis in HM/HSCT patients. Moreover, improvements in early diagnosis and treatment are urgently needed in these patients.

Clinical Experience of HeartMate II to HeartWare Left Ventricular Assist Device Exchange: A Multicenter Experience.

BACKGROUND: Despite improvements in pump design and durability, left ventricular assist device patients still suffer from life-threatening complications such as pump thrombosis (PT) and infection, often necessitating device exchange. Surgical exchange from HeartMate II (HM2; Abbott, Pleasanton, CA) to another HM2 is safe and associated with low mortality, but recurrent device thrombosis rates are high. Switching from axial-flow to centrifugal-flow pump, such as the HeartWare ventricular assist device (HVAD; Medtronic, Framingham, MA) may offer certain advantages due to it being a smaller, newer generation device, although there are limited data to support this strategy. Herein, we aimed to assess the surgical approach and feasibility, safety, and outcomes of surgical exchange from HM2 to HVAD. METHODS: We evaluated HM2 patients who underwent device exchange to HVAD due to PT or infection at 4 large-volume left ventricular assist device implant centers. RESULTS: Twenty-four patients underwent HM2 to HVAD exchange due to PT (92%) and refractory infection (8%). Patients were male (75%), white (88%), with ischemic cardiomyopathy (54%), Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) scale level 1-3 (90%), and destination therapy (62%). The majority underwent redo-sternotomy (79%) and the remainder underwent minimally invasive thoracotomy with subcostal approach. The existing HM2 outflow graft was maintained in 79% of cases. Recurrent PT was noted in 9% of patients. Mortality was 8% at 30 days and 33% at 1 year. CONCLUSIONS: The surgical exchange from a HM2 to HVAD is safe and feasible, despite the differences in device specifications and surgical adaptation required. Newer-generation pumps are increasingly considered for exchange in the setting of HM2 device complication, and increasing experience with modified surgical approaches may be valuable in the current era.

Sofosbuvir-Based Therapy in Hepatitis C Virus-Infected Cancer Patients: A Prospective Observational Study.

BACKGROUND: Data are sparse on treatment of chronic hepatitis C virus (HCV) in cancer patients. We evaluated the efficacy and safety of sofosbuvir-based therapy (SOFBT) in cancer patients. METHODS: Patients treated with SOFBT at our center during 2014-2017 were included in a prospective observational study. Efficacy [sustained virologic response at 12 weeks after the end of treatment (SVR12)], cancer-related outcomes and adverse events (AEs) were assessed. RESULTS: We included 153 patients. Most were men (109; 71%), white (92; 60%), non-cirrhotic (105; 69%), and with HCV genotype 1 (110; 72%). The most common cancers were hepatocellular carcinoma (HCC) (27; 18%) and multiple myeloma (14; 9%). The overall SVR12 rate was 91% (128/141). SVR12 was 100% in patients treated with ledipasvir/sofosbuvir for 8 weeks. Of the 32 patients initially excluded from cancer clinical trials because of HCV, 27 (84%) were granted cancer therapy access after starting SOFBT. Six patients with indolent non-Hodgkin's lymphoma (NHL) received SOFBT without cancer treatment. Two achieved complete remission, one had partial remission, and two had stable cancer. Within 6 months after SOFBT, 5% (6/121) of patients in remission or with stable cancer, had progression or recurrence (two with HCC and one each with esophageal cancer, cholangiocarcinoma, NHL, and tonsillar cancer). No de novo HCCs occurred. AEs were most commonly grade 1-2 (90%). CONCLUSIONS: SOFBT in HCV-infected cancer patients is effective and safe, may permit access to investigational cancer therapy expanding treatment options, may induce remission of NHL, and may be used for 8 weeks.

Leukopenia and lack of ribavirin predict poor outcomes in patients with haematological malignancies and respiratory syncytial virus infection.

Objectives: Respiratory syncytial virus (RSV) infection causes morbidity and mortality in cancer patients. However, studies describing this infection in patients with haematological malignancies are scarce. We sought to evaluate the clinical impact of RSV infection on this patient population. Methods: We reviewed the records of patients with haematological malignancies and RSV infections cared for at our institution between January 2000 and March 2013. Results: Of the 181 patients, 71 (39%) had AML, ALL or myelodysplastic syndrome, 12 (7%) had CML or CLL, 4 (2%) had Hodgkin lymphoma, 35 (19%) had non-Hodgkin lymphoma and 59 (33%) had multiple myeloma. Most patients [117 (65%)] presented with an upper respiratory tract infection (URTI) and 15 (13%) had a subsequent lower respiratory tract infection (LRTI). The overall LRTI rate was 44% and the 90 day mortality rate was 15%. Multivariable regression analysis showed that having both neutropenia and lymphocytopenia (adjusted OR = 7.17, 95% CI = 1.94-26.53, P < 0.01) and not receiving ribavirin-based therapy during RSV URTI (adjusted OR = 0.03; 95% CI = 0.01-0.11, P < 0.001) were independent risk factors for LRTI. Having both neutropenia and lymphocytopenia at RSV diagnosis was also a risk factor for death at 90 days after RSV diagnosis (adjusted OR = 4.32, 95% CI = 1.24-15.0, P = 0.021). Conclusions: Patients with haematological malignancies and RSV infections, especially those with immunodeficiency, may be at risk of LRTI and death; treatment with ribavirin during RSV URTI may prevent these outcomes.

Vitamin D deficiency and degree of coronary artery luminal stenosis in women undergoing coronary angiography: a prospective observational study.

BACKGROUND AND AIMS: Low serum 25-OH D levels are associated with increased cardiovascular morbidity and mortality. Recent studies have linked 25-OH D deficiency with the presence of CAD. Women, especially post-menopausal, tend to suffer from accelerated atherosclerosis, along with vitamin D deficiency. In the present study we sought to investigate whether there is a direct association of coronary artery luminal stenosis with 25-OH D deficiency in women. PATIENTS AND METHODS: We enrolled women aged >40 who were scheduled to undergo elective coronary angiography between 3/2011 and 10/2016 in a prospective observational study. RESULTS: We included a total of 105 women. Patients had hypertension (73%), hyperlipidemia (54%), diabetes (29%), smoking (31%), family history of CAD (62%), and known CAD (21%). Median 25-OH D levels were 15.8 ng/mL (range, 3.9-79). Patients had left-anterior descending (31%), left circumflex (22%), and right coronary artery disease (26%); 27% had 2-vessel and 11% had 3-vessel disease. There was a significant inverse correlation between 25-OH D levels and the degree of maximum luminal stenosis. The burden of CAD increased across categories of worsening 25-OH D deficiency. CONCLUSIONS: Vitamin D deficiency is associated with the degree of luminal stenosis and burden of CAD in women undergoing coronary angiography. Future studies should investigate if the repletion of 25-OH D impacts the progression of CAD and cardiovascular mortality.

Mixed Mycobacterium Avium-Intracellulare and Serratia Marcescens Cellulitis of the Breast in an HIV-Negative Patient with Breast Cancer: A Case Report.

Mycobacterium avium-intracellulare (MAI) causes pulmonary infection in patients with chronic lung diseases or severe T-cell deficiency. Cutaneous manifestations caused by MAI are rare and the few cases reported describe mostly patients with hematologic malignancies who were treated with highly immunosuppressive agents. Herein, we report a case of a breast cancer survivor who developed chronic breast cellulitis due to MAI, following localized breast cancer treatment.

Management of Multiple Myeloma Complicated by Hepatitis C Virus Reactivation: The Role of New Antiviral Therapy.

Reactivation of chronic hepatitis C virus (HCV) infection has been reported in cancer patients receiving chemotherapy. In this study, we report the first case, to our knowledge, of thalidomide-induced acute exacerbation and reactivation of chronic HCV infection complicating management of multiple myeloma. Sofosbuvir-based antiviral therapy helped achieve viral clearance and normalization of liver enzymes, thus allowing access to future potentially life-saving chemotherapy agents.

Hepatitis C Virus Infection in Patients Undergoing Hematopoietic Cell Transplantation in the Era of Direct-Acting Antiviral Agents.

There is paucity of literature regarding hepatitis C virus (HCV) infection in hematopoietic cell transplant (HCT) recipients. In the study described herein we evaluated several aspects of HCV infection in HCT recipients, including the impact of this infection on cancer status, liver-related outcomes, mortality, and the role of antiviral treatment (AVT), including direct-acting antivirals (DAAs). The medical records of HCV-infected allogeneic and autologous HCT recipients, seen at The University of Texas MD Anderson Cancer Center from August 2009 to November 2015, were reviewed. Patients seen from August 1, 2009 to October 30, 2012 were reviewed retrospectively, whereas those seen from November 1, 2012 to November 30, 2015 were analyzed prospectively in an observational study. Of 434 HCV-infected cancer patients evaluated, 64 underwent 69 HCTs. Most (78%) underwent autologous transplantation. Thirteen percent of patients became HCV-seronegative post-HCT. Compared with patients who did not receive AVT, treated patients had fewer relapses of HCV-associated non-Hodgkin lymphomas (20% versus 86%; P = .015), higher 5-year survival rates (75% versus 39%; P = .02), and a trend toward lower rate of progression to cirrhosis (5% versus 21%; P = .06). AVT discontinuation rate post-HCT was 71% in those receiving IFN-containing regimens and 0% in those receiving DAAs (P < .01). AVT was effective in 12 of 37 patients (32%) and 11 of 13 patients (85%) receiving IFN-based and DAA regimens, respectively (P = .003). HCV is an important cause of morbidity and mortality in this population. HCV seropositivity can be lost post-HCT, posing a diagnostic challenge. Treatment of HCV infection in HCT recipients improves both oncologic and hepatic outcomes. These patients can be successfully treated with DAAs.

Impact of hepatitis E virus seropositivity on chronic liver disease in cancer patients with hepatitis C virus infection.

AIM: Immunocompromised patients can develop chronic hepatitis E virus (HEV) infection and progress to cirrhosis. Hepatitis C virus (HCV)-infected cancer patients who have received chemotherapeutic agents experience accelerated liver fibrosis progression. Our aim was to investigate the prevalence and impact of HEV seropositivity on liver-related outcomes in HCV-infected cancer patients. METHODS: As part of a prospective study of HCV-infected cancer patients conducted at our center, we investigate the characteristics associated with progression of their liver disease. RESULTS: Of the 115 patients tested, 13 (11%) were positive for HEV immunoglobulin G. HEV seropositivity was associated with advanced age (P = 0.004), race (P = 0.02), place of birth outside the USA (P = 0.021), cirrhosis (P = 0.027), history of reused needles/syringes during massive vaccination campaigns (P = 0.015) and coronary artery disease (P = 0.039). Overall, 47 (41%) of the patients had cirrhosis. Factors independently associated with cirrhosis were male sex (odds ratio [OR], 2.8; P = 0.028) and HEV seropositivity (OR, 4.1; P = 0.032). CONCLUSION: HEV seropositivity is present in 11% of HCV-infected cancer patients and seems to be associated with cirrhosis. Our results suggest that HEV screening should be implemented in HCV-infected patients with cancer.

Interferon-based treatment for patients with mycosis fungoides and hepatitis C virus infection: a case series.

BACKGROUND: Interferon (IFN) is a treatment option for both mycosis fungoides (MF) and hepatitis C virus (HCV) infection. Chemotherapy and anti-HCV treatment are generally not administered concurrently for fear of overlapping side effects. OBJECTIVE: Herein, we report on a subset of patients who received IFN-containing therapy for MF and HCV infection simultaneously. We aimed to evaluate whether concomitant treatment for MF and HCV is effective and well tolerated. METHODS: We reviewed the records of patients who were seen at MD Anderson Cancer Center from 2008 to 2013 with histologically confirmed MF and chronic HCV infection, and were treated with simultaneous focus on both diseases. RESULTS: Six HCV-infected patients with MF received simultaneous anti-HCV and anti-MF treatment with IFN-containing therapy. Two patients achieved sustained virological response (regarded as virological cure). They both received antiviral combination therapy with ribavirin. All patients experienced some improvement of their cutaneous lesions, with two of them achieving complete MF remission. All six patients developed side effects while receiving treatment; two of them had grade 4 toxic effects requiring treatment discontinuation. CONCLUSION: IFN-based therapy can be administered for MF and HCV infection concurrently to provide not only virological but also oncological benefits to chronically HCV-infected MF patients. However, this regimen is poorly tolerated. Further studies are warranted in this patient population, using different treatment combinations with improved efficacy, safety, and tolerability.
