An Immunological Non-responder Human Immunodeficiency Virus/Hepatitis C Virus Coinfected Patient: Considerations About a Clinical Case.

Human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infections are two chronic viral infections that share the same mode of transmission, making HIV/HCV coinfection frequent. Highly active antiretroviral therapy (HAART) was a turning point in HIV treatment and has been shown to successfully restore immune function and reduce the frequency of opportunistic infections. Despite a virological response to HAART, a proportion of patients fail to achieve substantial immune recovery, as measured by peripheral CD4 cell counts. Herein, we present the case of a patient with HIV/HCV coinfection who did not achieve successful immune function restoration despite HIV suppression and HCV treatment. Our goal is to promote discussion. Despite considerable advances in the understanding of the impact of HCV on HIV disease progression, there are many individual variables that influence a patient's immune function. In addition, we consider hypogammaglobulinemia as a possible contributor. Further understanding and improvement of immune reconstitution in patients infected with HIV remain an important field of scientific research.

Corynebacterium striatum Cardiac Device-Related Infective Endocarditis: The First Case Report in a Patient With a Cardiac Resynchronization Therapy Defibrillator Device and Review of the Literature.

Corynebacterium striatum (C. striatum) is a skin commensal agent, rarely described as a cause of infective endocarditis. We describe a case of a 48-year-old man, with multiple comorbidities with cardiac resynchronization therapy defibrillator (CRT-D) device implanted 1 year before. A cardiac device-related infective endocarditis (CDRIE) due to C. striatum, with vegetations in the tricuspid valve adjacent to the electrode lead and concomitant lumbar spondylodiscitis were diagnosed. The patient was treated initially with a 6-week course of vancomycin with sterile blood cultures and reduction of inflammatory parameters. Surgery was refused at this stage. Six weeks later, he was readmitted due to C. striatum bacteriemia recurrence, with vegetations adhering to the electrode wire, being treated with daptomycin 10mg/kg body weight, after presenting renal toxicity to vancomycin. CRT-D device was removed with implantation of epicardial cardiac resynchronization therapy pacemaker (CRT-P). To our knowledge, this might be the first description of C. striatum CDRIE in a patient with a CRT-D. In the five cases described in the literature of CDRIE by this agent, early removal of the pacemaker was performed with good results. In this case, the device was removed only after failure of medical treatment alone.

Subacute Hypophysitis with Panhypopituitarism as First Presentation of HIV and Syphilis Coinfection.

Infection by Treponema pallidum still represents a clinical challenge due to its various forms of presentation. HIV coinfection added diversity and changed the natural history of syphilis as a systemic infection. We present a rare case of subacute hypophysitis and panhypopituitarism due to an early active neurosyphilis in a previously unknown HIV coinfected patient.

Immune Reconstitution Inflammatory Syndrome: Opening Pandora's Box.

One of the purposes of antiretroviral therapy (ART) is to restore the immune system. However, it can sometimes lead to an aberrant inflammatory response and paradoxical clinical worsening known as the immune reconstitution inflammatory syndrome (IRIS). We describe a 23-year-old male, HIV1 infected with a rapid progression phenotype, who started ART with TCD4+ of 53 cells/mm3 (3,3%) and HIV RNA = 890000 copies/mL (6 log). Four weeks later he was admitted to the intensive care unit with severe sepsis. The diagnostic pathway identified progressive multifocal leukoencephalopathy, digestive Kaposi sarcoma, and P. aeruginosa bacteraemia. Five weeks after starting ART, TCD4+ cell count was 259 cells/mm3 (15%) and HIV RNA = 3500 copies/mL (4 log). He developed respiratory failure and progressed to septic shock and death. Those complications might justify the outcome but its autopsy opened Pandora's box: cerebral and cardiac toxoplasmosis was identified, as well as hemophagocytic syndrome, systemic candidiasis, and Mycobacterium avium complex infection. IRIS remains a concern and eventually a barrier to ART. Male gender, young age, low TCD4 cell count, and high viral load are risk factors. The high prevalence of subclinical opportunistic diseases highlights the need for new strategies to reduce IRIS incidence.

Deepening our understanding of quality improvement in Europe (DUQuE): overview of a study of hospital quality management in seven countries.

INTRODUCTION AND OBJECTIVE: This paper provides an overview of the DUQuE (Deepening our Understanding of Quality Improvement in Europe) project, the first study across multiple countries of the European Union (EU) to assess relationships between quality management and patient outcomes at EU level. The paper describes the conceptual framework and methods applied, highlighting the novel features of this study. DESIGN: DUQuE was designed as a multi-level cross-sectional study with data collection at hospital, pathway, professional and patient level in eight countries. SETTING AND PARTICIPANTS: We aimed to collect data for the assessment of hospital-wide constructs from up to 30 randomly selected hospitals in each country, and additional data at pathway and patient level in 12 of these 30. MAIN OUTCOME MEASURES: A comprehensive conceptual framework was developed to account for the multiple levels that influence hospital performance and patient outcomes. We assessed hospital-specific constructs (organizational culture and professional involvement), clinical pathway constructs (the organization of care processes for acute myocardial infarction, stroke, hip fracture and deliveries), patient-specific processes and outcomes (clinical effectiveness, patient safety and patient experience) and external constructs that could modify hospital quality (external assessment and perceived external pressure). RESULTS: Data was gathered from 188 hospitals in 7 participating countries. The overall participation and response rate were between 75% and 100% for the assessed measures. CONCLUSIONS: This is the first study assessing relation between quality management and patient outcomes at EU level. The study involved a large number of respondents and achieved high response rates. This work will serve to develop guidance in how to assess quality management and makes recommendations on the best ways to improve quality in healthcare for hospital stakeholders, payers, researchers, and policy makers throughout the EU.

Rare posterior reversible encephalopathy syndrome in a patient with HIV.

Posterior reversible encephalopathy syndrome (PRES) is an uncommon neurological disorder, characterised by the rapid onset of neurological deficits and characteristic neuroimaging findings-cerebral oedema with a typical preference for the posterior white matter. We report a case of a 59-year-old woman with an untreated HIV infection and hypertension with a PRES diagnosis and a rare involvement of the basal ganglia and brainstem, with microhemorrhages. HIV infection, particularly if untreated, is associated with an inflammatory status and therefore endothelial damage and dysfunction that might have an important role in predisposing acute hypertensive crisis and PRES.

From Clinical Presentation to the Outcome: the Natural History of PML in a Portuguese Population of HIV Infected Patients.

BACKGROUND: Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease of the central nervous system, associated with immunosuppression states. As there are only some non-published documents concerning PML in HIV infected patients in Portugal, we pretend to characterize natural history of PML infection in a population of HIV patients. METHODS: We retrospectively reviewed, from 1992 to 2009, PML cases in a population of 724 HIV infected patients followed in our institution. Clinical, biological, imagery features and outcomes were characterized. RESULTS: Twenty-five (3.45%) patients were identified as having PML. The mean time between HIV and PML diagnosis was 20.4 months. PML was the presentation of HIV infection in 40% of the patients, and 92% had CD4 T cell count lower than 200/mm(3). Paresis was the most common clinical presentation. No specific characteristics were found in cerebrospinal fluid and JCV DNA was positive in 3 of 7 patients. MRI revealed characteristic findings. Combined antiretroviral therapy was started or changed in 96% of the patients. Neurological condition got worse in 12 patients. From the 14 deaths, 5 were directly attributed to PML progression. Follow-up was lost in 8 patients. CONCLUSIONS: PML was the presentation of HIV infection in more than 1/3 of patients, frequently associated with advanced immunocompromise. MRI sensitivity to PML is high, and JCV DNA determination in CSF was not revealed to be sensible. PML diagnosis should be taken into account in HIV patients presenting any neurological symptoms, and HIV infection should be suspected when radiological findings suggest PML lesions even in previously healthy individuals. KEYWORDS: Progressive multifocal leukoencephalopathy; JC virus; Human immunodeficiency virus; Demyelinating disease.

Quality, risk management and patient safety: the challenge of effective integration.

Nowadays we observe the development of three waves of intervention and change within healthcare services: quality management, risk management and patient safety. The Patient Safety movement has been launched at international level as a consequence of the Institute of Medicine's report--To Err is Human, and today patient safety constitutes one basic dimension of health quality subjected to the direct intervention of supranational entities (WHO, EU) and Member States' Governments. The objective of this paper is to raise awareness about the value of quality improvement (QI) methodologies and tools to sustainable healthcare quality outcomes.

Selecting indicators for patient safety at the health system level in OECD countries.

BACKGROUND: Concerns about patient safety have arisen with growing documentation of the extent and nature of harm. Yet there are no robust and meaningful data that can be used internationally to assess the extent of the problem and considerable methodological difficulties. PURPOSE: This article describes a project undertaken as part of the Organization for Economic Cooperation and Development (OECD) Quality Indicator Project, which aimed at developing an initial set of patient safety indicators. METHODS: Patient safety indicators from OECD countries were identified and then rated against three principal criteria: importance to patient safety, scientific soundness, and potential feasibility. Although some countries are developing multi-source monitoring systems, these are not yet mature enough for international exchange. This project reviewed routine data collections as a starting point. RESULTS: Of an initial set of 59 candidate indicators identified, 21 were selected which cover known areas of harm to patients. CONCLUSIONS: This project is an important initial step towards defining a usable set of patient safety indicators that will allow comparisons to be made internationally and will support mutual learning and quality improvement in health care. Measures of harm should be complemented over time with measures of effective improvement factors.
