Características de pacientes asmáticos ingresados en una unidad de cuidados respiratorios intermedios

Introduction

Intermediate respiratory care units (IRCU) provide continuous monitoring and non-invasive mechanical ventilation (NIMV) in patients with severe respiratory failure who are usually admitted to intensive care units (ICU). The usefulness of IRCU in managing severe asthma exacerbations has never been evaluated.

Methods

Clinical data were prospectively and systematically compiled from patients admitted to the IRCU with a principal diagnosis of bronchial asthma exacerbation. We assessed therapeutic failure (intubation or exitus) and patient evolution up until 6 months after discharge compared with a group of patients admitted to a conventional hospital ward, paired for age and sex, and with the same principal diagnosis.

Results

A total of 74 asthma patients were included (37 admitted to IRCU and 37 to the hospital ward) with a mean age (± SD) of 58 ± 20 years, who were predominantly women (67%), with previous diagnosis of asthma and persistent asthma treatment. The main cause of admittance to the IRCU was severe respiratory failure. The patients who were admitted to the IRCU presented more radiological affectation (alveolar infiltrates) and had significantly higher pCO₂. Ten patients admitted to the IRCU required NIMV. There were no differences between the two groups regarding either therapeutic failure or the 6-month follow-up after discharge.

Conclusions

Patients with severe asthma exacerbations can be managed in an IRCU while avoiding hospitalization in an ICU and demonstrating a prognosis similar to milder exacerbations treated in conventional hospital wards.     

Soins palliatifs chez les patients en insuffisance cardiaque terminale

Purpose

Heart failure is a common disease and its progression to end-stage heart failure is responsible of high mortality. The aim of this retrospective study was to assess the access to integrated palliative care to the usual management, 6 months prior to their death, and especially during the last hospitalization.

Patients and methods

A retrospective study was performed in patients who died of heart failure in 2009 in two hospitals. The analysis was performed on 20 cases of each institution. The records of consecutive patients were included in an anti-chronological order from 31st December 2009.

Results

For their last hospitalization, 37 patients (93%) were hospitalized in emergency. Within 3 days prior to death, the most frequent symptoms were dyspnea (n = 33, 82%), and pain (n = 30, 75%). Therapeutic most frequently used were oxygen (n = 31, 77%) and analgesics (n = 30, 75%). No patient was seen by a psychologist. The decision to limit treatment for comfort care was reported for 24 patients (60%) and the median of the average time between the decision and death was 2 days (Q1–Q3, 1–5 days).

Conclusion

Patients with terminal heart failure have many symptoms often requiring multidisciplinary care. This type of study relating practices shows that there is still a lot to do to integrate palliative care in the usual management of patients with heart failure.     

Características clínicas y pronóstico de la neumonía adquirida en la comunidad causada por Staphylococcus aureus resistente a la meticilina

Introduction

The aim of this study is to describe the epidemiological and clinical features, treatment and prognosis of community-acquired pneumonia (CAP) caused by methicillin-resistant Staphylococcus aureus (MRSA) in two different geographic regions where community-acquired MRSA (CA-MRSA) infections have different frequencies.

Methods

Observational study of patients admitted to two hospitals (one in Argentina, the other in Spain) between March 2008 and June 2012.

Results

We documented 16 cases of CAP caused by MRSA. MRSA accounted for 15 of 547 (2.7%) cases of CAP in Hospital Rodolfo Rossi and 1 of 1258 (0,08%) cases at the Hospital Universitari de Bellvitge (P ≤ .001). Most patients were young and previously healthy. Multilobar infiltrates, cavitation and skin and soft tissue involvement were frequent. All patients had positive blood cultures. Five patients required admission to the intensive care unit. Early mortality (≤ 48 hours) was 19%, and overall mortality (≤ 30 days) was 25%.

Conclusion

CAP caused by MRSA causes high morbidity and mortality rates. It should be suspected in areas with a high prevalence of CA-MRSA infections, and especially in young and healthy patients who present with multilobar pneumonia with cavitation. Mortality is mainly related to septic shock and respiratory failure and occurs early in most cases.     

L’éducation nutritionnelle du patient coronarien en pratique

Background

The Mediterranean diet is one of the food models which showed its ability at the patient at high cardiovascular risk in numerous cohort studies and two major interventional studies: Lyon Heart Study in 1999 and PREDIMED in 2013.

Aim of the study

Propose a practical assistance in the analysis of the dietary habits of the coronary patient with a simplified food frequency questionnaire.

Patients and methods

Hundred coronary patients followed a program of cardiac rehabilitation and benefited from a nutritional education. The analysis of their dietary habits was made with the questionnaire of frequency of consumption of Rennes upon their arrival and 6 months later. We have coded again these data by means of a simplified questionnaire with 15 items and compared the results and their evolution in 6 months.

Results

On studied 200 questionnaires, the score of Rennes was 10.6 ± 4.5 and the simplified score 8.2 ± 3.4 with a coefficient of correlation of Pearson r = 0.94 (0.91–0.95) at risk P < 0.0001. Initial scores were respectively 8.0 ± 4.4 and 6.3 ± 3.4 (r = 0.93) and the scores at 6 months 13.1 ± 2.9 and 10.1 ± 2.2 (r = 0.86). The evolution of the scores of 100 patients were respectively 14.2 ± 11.7% and 12.6 ± 11% (P < 0.26).

Conclusion

The use of a simplified questionnaire allows to analyze the dietary habits of the coronary patient and to estimate their evolution during a therapeutic educational program.     

Résultats diagnostiques à court terme et pronostiques à long terme chez des patients avec syncopes inexpliquées : résultats d’un série menée en centre hospitalier

Objective

Evaluate the diagnostic and prognostic input of head-up tilt test in the exploration of unexplained syncope.

Method

Between January 2009 and December 2012, all patients undergoing a head-up tilt test for recurrent syncope were studied. Follow-up data were obtained using telephone interviews and medical record reviews.

Results

A head-up tilt test was realized in 77 patients (47.8 ± 20 years, 53% female) for an exploration of syncope. The tilt test elicited syncope or pre-syncope in 57 patients (74%). The positive response included vaso-vagal syncope in 53 patients and psychogenic syncope in 4 patients. After a mean follow-up of 32 ± 11 months (range 6–54 months), 90% of patients had not a recurrence of syncope. Of note, the incidence of recurrence was the same regardless of whether the patients had a positive (n = 5/48; 10%) or a negative head-up tilt test response (n = 2/19; 10%).

Conclusion

The tilt test has a certain diagnostic value in the exploration of unexplained syncope. Recurrence rate of syncope after a tilt test is low. However, our study suggests no correlation between head-up tilt test results and the likelihood of recurring syncope.     

Evolución del uso de la ventilación mecánica no invasiva en enfermedad pulmonar obstructiva crónica en una región española, 1997-2010

Introduction

Noninvasive mechanical ventilation (NIV) appeared in the 1980s as an alternative to invasive mechanical ventilation (IMV) in patients with acute respiratory failure. We evaluated the introduction of NIV and the results in patients with acute exacerbation of chronic obstructive pulmonary disease in the Region of Murcia (Spain).

Subjects and methods

A retrospective observational study based on the minimum basic hospital discharge data of all patients hospitalised for this pathology in all public hospitals in the region between 1997 and 2010. We performed a time trend analysis on hospital attendance, the use of each ventilatory intervention and hospital mortality through joinpoint regression.

Results

We identified 30.027 hospital discharges. Joinpoint analysis: downward trend in attendance (annual percentage change [APC] = −3.4, 95% CI: − 4.8; −2.0, P <.05) and in the group without ventilatory intervention (APC = −4.2%, −5.6; −2.8, P <.05); upward trend in the use of NIV (APC = 16.4, 12.0; 20. 9, P <.05), and downward trend that was not statistically significant in IMV (APC = −4.5%, −10.3; 1.7). We observed an upward trend without statistical significance in overall mortality (APC = 0.5, −1.3; 2.4) and in the group without intervention (APC = 0.1, −1.6; 1.9); downward trend with statistical significance in the NIV group (APC = −7.1, −11.7; −2.2, P <.05) and not statistically significant in the IMV group (APC = −0,8, −6, 1; 4.8). The mean stay did not change substantially.

Conclusions

The introduction of NIV has reduced the group of patients not receiving assisted ventilation. No improvement in results was found in terms of mortality or length of stay.     

Influencia del fenómeno migratorio sobre la tuberculosis en una zona semiurbana

Aims

To describe the epidemiology of tuberculosis and analyzing the differences among native and immigrant patients in Area III of the Region of Murcia.

Methods

Cohort study of tuberculosis cases reported to the Epidemiological Surveillance Service from 2004 to 2009. Data collection was performed through the System of Notification Diseases, reviewing clinical files and epidemiological surveys.

Results

One hundred sixty two cases were detected; 110 (67.9%) were immigrants, whose incidence rates ranged from 43.4 to 101.2 cases per 100,000 inhabitants. Ecuador (42.7%), Bolivia (30%) and Morocco (18.2%) were the main nationalities.Immigrants were younger than Spanish population (P < .001). The overall diagnostic delay was 50.5 days: 59.5 in Spanish and 47 in foreigners. Moroccans had higher proportions of extrapulmonary TB (P = .02). Mainly, immigrant population took treatment with four drugs (P < .001). Natives had better treatment adherence (P = .04). Spanish cases tuberculosis were associated with smoking (P < .001), the same as alcohol consumption (P = .01) and injection drug use (P < .001), nevertheless in the foreign-born population the most relevant risk factor was overcrowding (P < .001).

Conclusions

The incidence tuberculosis rates are higher among immigrant population, whose the main risk factor is overcrowding. In contrast, Spanish cases are associated with toxic substances consumption and increasing age.     

Infecciones de piel y partes blandas en pacientes hospitalizados: factores epidemiológicos,microbiológicos,clínicos y pronósticos

Introduction

Skin and soft-tissue infections (SSTIs) are a frequent cause of consultation in emergence services, and complicated cases require hospitalization. However there are few data in our setting about the clinical characteristics of these infections.

Material and methods

A retrospective review of hospital admitted patients with a diagnosis of folliculitis, cellulitis, erysipelas, abscesses, hidradenitis, furuncle, impetigo, fasciitis and Fournier's gangrene. Cases were extracted from the data base of diagnostic codes of the Archive and Clinical Documentation Department of Son Llàtzer Hospital from January 2002 to November 2011.

Results

We studied 996 episodes in 841 hospitalized patients with any diagnosis of SSTIs. Cellulitis/erysipelas (66.7%) was the most frequently diagnosed condition, with 77% of all SSTIs being community acquired, and the majority of patients had comorbidities, mainly diabetes (33%) and heart failure (17.7%). The most frequent isolated microorganism was S. aureus (35.1%), in 19 (12.9%) cases with methicillin-resistance (MRSA), 84.2% of them were nosocomial or health care acquired. Monotherapy with aminopenicillin with clavulanic acid was the empiric treatment most frequently used (35.5%). New antibiotics for Gram-positive cocci (linezolid, daptomycin, and tigecycline) were used in patients with comorbidities that presented more complications (P < .001) and more risk of mortality (P = .001). During admission 10.9% of patients died, but only in 2.7% of them mortality was related to the SSTIs.

Conclusions

SSTIs attended most frequently in hospitalized patients are mainly cellulitis/erysipela, the majority community acquired. MRSA infections are mainly health care related. Use of new antibiotic for Gram-positive cocci was limited.     

Colonización nasal por Staphylococcus aureus en estudiantes de medicina: importancia en la transmisión hospitalaria

Background

Staphylococcus aureus is the main pathogen causing nosocomial infections. Health professionals, including medical students, could be a source of transmission. The aims of the study were to determine the rate of nasal carriage of S. aureus susceptible and resistant to methicillin (MRSA) and evaluate the knowledge and adherence that students had about hand hygiene.

Methods

The study included medical students attached to the Hospital Universitario 12 de Octubre (Madrid, Spain). We collected samples from both nasal vestibules, and the antimicrobial susceptibility was determined on all isolates. Data collection was performed using a self-administered questionnaire that included risk factors for colonization, hygiene habits and knowledge of hand hygiene protocols.

Results

Of the 140 students included, 55 (39.3%) were colonized by S. aureus, and 3 (2,1%) by MRSA. The exposure to antibiotics in the last 3 months was lower in colonized students (12.3% vs. 25.9%, P = .03). Self-assessment showed that 56.4% of students almost never washed their hands before to attending to the first patient, and only 38.6% always washed after examining patients. More than a third (35.7%) ignored the hand hygiene protocol, and 38.6% had not received specific formation.

Conclusions

Medical students should be included in hospital infection control programs. Hand hygiene training should be given to students before they begin their practices in the hospital.     

Orientation des patients par leur médecin généraliste vers les secteurs hospitaliers publics ou privés en France : étude épidémiologique prospective du réseau Sentinelles

Purpose

In-patients characteristics generate cost differences between hospitals. In France, there are few data on the characteristics on the patients referred to hospitals by their general practitioners (GPs) and none on the predictors of referral to the public or for-profit hospitals. The aim of this study was to analyze those characteristics and the predictors of referral to the public or for-profit hospitals.

Methods

We collected, prospectively, the request for hospitalizations made by the GPs of the Sentinelles network in France, from 2007 to 2009. Patients’ characteristics and also the reasons for that request were analyzed. A logistic regression was used to compare the population between local hospitals.

Results

Ten thousand seven hundred and eighteen statements were collected. The median age was 73 years. Patients were women in 51% of the cases, and only 14% of the hospitalizations had been planned. Hospitalization in the public sector was preferred for young children and the elderly (P < 0.001). When compared to the patients referred to the private sector, patients addressed to the public sector were more often seen for emergencies (OR: 2.3 [2.0–2.8]), by a doctor different from their referring GP (OR: 1.7 [1.4–2.1]) and out of the GP's office. The reasons for hospital admission were different depending on the sector of hospitalization (P < 0.001), patients addressed to the public sector hospitals presented with greater comorbidity or more complex diagnosis (for example: feeling ill, fainting or syncope and fever) or a greater disability (for example: stroke, neurological and psychiatric diseases).

Conclusion

This study suggests that GPs send their patients to the public or for-profit hospitals according to criteria of severity, comorbidity and disability.     

Utilidad de la ultrasonografía endobronquial radial en el diagnóstico de lesiones pulmonares periféricas. Estudio controlado con fluoroscopia

Introduction

Fluoroscopy-guided bronchoscopy is usually performed for the diagnosis of peripheral pulmonary lesions (PPL), but the diagnostic yield varies widely among studies. Endobronchial ultrasound (EBUS) can increase the diagnostic yield of bronchoscopic diagnosis of PPL.

Objective

To compare the diagnostic yield of fluoroscopy-guided bronchoscopy and EBUS with fluoroscopy-guided bronchoscopy in the study of PPL.

Methods

All patients who underwent bronchoscopy to study PPL from January 2009 to December 2012 were prospectively included. 145 consecutive patients were randomly distributed in two groups: EBUS and fluoroscopy (50 patients, 71.3 ± 8.2 years) or fluoroscopy alone (95 patients, 68 ± 10.5 years). The mean diameter of the lesions was 41.97 ± 19.22 mm. Cytological brushing and transbronchial biopsies were obtained. All procedures were performed under fluoroscopic guidance with intravenous conscious sedation. EBUS was performed using an endoscopic ultrasound system equipped with a 20-MHz radial miniprobe introduced via a guide-sheath. Bronchoscopist, cytologist, study protocol, techniques and tools were the same throughout the whole study.

Results

129 (89%) patients had malignant disease. A diagnosis with bronchoscopy was established in 105 (72.4%) patients. EBUS plus fluoroscopy obtained a diagnostic yield in 78% of patients and fluoroscopy alone in 69.5% (non-significant). In contrast, for lesions smaller than 30 mm, EBUS plus fluoroscopy guidance provided significantly greater diagnostic performance than fluoroscopy alone (90 vs. 52%; P = .05).

Conclusions

Bronchoscopy under EBUS plus fluoroscopy guidance is a technique that has become useful for the diagnostic of LPPs, especially those smaller than 30 mm in diameter.     

Uso rutinario del Pneumonia Severity Index en el servicio de urgencias: efecto sobre los indicadores de proceso y resultado en neumonía adquirida en la comunidad

Objective

To evaluate process-of-care indicators (inappropriate hospitalisation, suitability and early antibiotic treatment) and outcome indicators (length of hospital stay, hospital readmission, ICU admission, and mortality) in the management of community-acquired pneumonia (CAP) when the SEPAR/IDSA guidelines were applied.

Patients and methods

An observational retrospective study conducted on patients diagnosed with CAP during the first semester of 2007 and 2008 (186 and 161 patients, respectively) in the emergency unit of a general hospital. Differences in the process-of-care and outcome indicators between 2007 and 2008 (with and without the Pneumonia Severity Index [PSI]) were evaluated. Moreover, the indicators were compared with those obtained in 2006 (110 patients), when the current guidelines were those of SEQ/ATS.

Results

The SEPAR/IDSA guidelines improved the following process-of-care indicators: appropriateness of treatment, unjustified hospital readmission (39.4% in 2006 vs. 8.5% in 2007 [P < .001], and 17,2% in 2008 [P = .005]), and early treatment. However, outcome indicators did not change. In 2008, a decrease in the mortality of the patients of risk classes IV-V in which the PSI had been estimated was observed in comparison with the patients in which the PSI was not estimated (2.3% vs. 28.3%; P < .001). Moreover, the mortality rate of the patients of risk classes IV-V in which the PSI had been estimated was lower than those measured using the SEQ/ATS guidelines (22.7%; P = .003).

Conclusion

SEPAR/IDSA guidelines decreased the unjustified hospital readmission. In the second year of its application an increase in the number of patients who received early treatment, and a decrease of the mortality rate of the patients of risk classes IV-V in which the PSI had been estimated, were also observed.     

Ancho de distribución eritrocitaria y predicción adicional del riesgo de hemorragia mayor en el síndrome coronario agudo sin elevación del ST

Introduction and objectives

Red cell distribution width has been linked to an increased risk for in-hospital bleeding in patients with non–ST-segment elevation acute coronary syndrome. However, its usefulness for predicting bleeding complications beyond the hospitalization period remains unknown. Our aim was to evaluate the complementary value of red cell distribution width and the CRUSADE scale to predict long-term bleeding risk in these patients.

Methods

Red cell distribution width was measured at admission in 293 patients with non–ST-segment elevation acute coronary syndrome. All patients were clinically followed up and major bleeding events were recorded (defined according to Bleeding Academic Research Consortium Definition criteria).

Results

During a follow-up of 782 days [interquartile range, 510-1112 days], events occurred in 30 (10.2%) patients. Quartile analyses showed an abrupt increase in major bleedings at the fourth red cell distribution width quartile (> 14.9%; P = .001). After multivariate adjustment, red cell distribution width > 14.9% was associated with higher risk of events (hazard ratio = 2.67; 95% confidence interval, 1.17-6.10; P = .02). Patients with values ≤ 14.9% and a CRUSADE score ≤ 40 had the lowest events rate, while patients with values > 14.9% and a CRUSADE score > 40 points (high and very high risk) had the highest rate of bleeding (log rank test, P < .001). Further, the addition of red cell distribution width to the CRUSADE score for the prediction of major bleeding had a significant integrated discrimination improvement of 5.2% (P < .001) and a net reclassification improvement of 10% (P = .001).

Conclusions

In non–ST-segment elevation acute coronary syndrome patients, elevated red cell distribution width is predictive of increased major bleeding risk and provides additional information to the CRUSADE scale.Full English text available from: www.revespcardiol.org/en     

Hallazgos radiológicos en pacientes con esquistosomiasis importada

Introduction

Imaging techniques, primarily ultrasound, are useful in the diagnosis and monitoring of patients with schistosomiasis in endemic areas.

Methods

Study of 219 patients treated in sub-Saharan Tropical Medicine Unit with a diagnosis of imported schistosomiasis by imaging techniques investigations including plain abdominal radiography and ultrasound.

Results

A total of 17.8% of patients who had an abdominal X-ray showed findings suggestive of schistosomiasis, in most cases bladder calcifications. In 73 patients (41%) ultrasound showed pathological findings, mainly diffuse or focal wall thickening (26 patients), nodular lesions (n = 14), and pseudopolyps (n = 8). One patient, who had a large bladder mass (9 cm) and bilateral ureterohydronephrosis, was finally diagnosed with squamous cell carcinoma of the bladder. Ultrasound liver abnormalities were found in 10 patients, 4 with signs of portal hypertension, of which 3 had the characteristic periportal fibrosis in schistosomiasis.

Conclusion

Imaging studies, especially abdominal and bladder ultrasound, are useful for diagnosis, the study of disease and monitoring of patients with schistosomiasis in non-endemic countries.     

Significado clínico del aislamiento de Staphylococcus aureus en muestras de orina

Introduction

To evaluate the clinical significance of the isolation of Staphylococcus aureus in urine samples.

Methods

A retrospective study was performed on adult patients identified from a microbiology database in a 200-bed general hospital between the years 2000 and 2009. The demographic data, comorbidities, and risk factors, were reviewed, particularly those associated with the concomitant isolation of S. aureus in blood cultures.

Results

The frequency of S. aureus found in urine samples was 0.63%. A total of 43 patients (mean age 68.7 years [SD ± 16], and 58.1% males) were identified in the database. A Charlson comorbidity index > 3 was observed in 20.9%. Concurrent bacteremia was seen in 48.8%. Two groups of patients were distinguished: with concomitant bacteremia (n = 21) or without (n = 22). Intervention in the urinary tract significantly predicted (P = .00004) bacteriuria without bacteremia (81.8%), compared to bacteremia cases (19%). The attributable mortality was 47.6% in patients with bacteremia compared to non-bacteremia (no deaths), even though the appropriate antibiotic treatment was more frequent among patients with bacteremia (92% and 60%, respectively).

Conclusion

The presence of S. aureus in urine was accompanied by bacteremia in half of the cases, but in patients without previous urinary tract intervention such a possibility increased to 81%. Concomitant bacteremia predicts a worse prognosis even with appropriate treatment.     

Utilización de procalcitonina y proteína C reactiva como marcadores de infección en la neutropenia febril de pacientes sometidos a trasplante de progenitores hematopoyéticos

Introduction and objective

Neutropenia is a frequent sign in patients who are going to have a haematopoietic stem cell transplant (HSCT). Infection is an important complication in these patients, which is favoured by immunosuppression and the degree of neutropenia. This study aims to evaluate the diagnostic usefulness of procalcitonin (PCT) and C-reactive protein (CRP) in onco-haematological patients undergoing chemotherapy and HSCT to determine the origin of the fever.

Patients and methods

PCT and CRP values were measured in 30 episodes of febrile neutropenia: before starting chemotherapy, appearance of neutropenia, onset of fever, days 1, 2, 3 and 6 after the onset of fever, and when the febrile episode ended. The episodes were classified as 5 bacteraemia, 3 microbiologically documented infections, 10 clinical infections, and 12 fevers of unknown origin.

Results

The highest PCT mean values corresponded to the group of patients with bacteraemia. Statistically significant differences (P = .04) were found on the second day after the onset of fever. The cut-off point of 0.5 ng/ml showed a sensitivity of 66% and a specificity of 75%. PCR results showed statistically significant differences on days 1, 2 and 3 after the onset of fever (P = .01, P = .003, and P = .002, respectively). The cut-off point of 7.5 mg/L had a sensitivity of 88% and a specificity of 58%.

Conclusions

The combination of PCT and CRP is an insufficient method to detect bacterial infections and may not replace the proper clinical and microbiological diagnosis.     

Amylose cardiaque : à propos d’une série de 14 patients,description et facteurs pronostiques

Purpose

Cardiac amyloidosis is rare. The objective of this study was to report on a case series of 14 patients with cardiac amyloidosis and to study the prognostic factors.

Methods

Monocentric retrospective study of all adult patients who presented with cardiac amyloidosis, diagnosed at the Georges-Pompidou European hospital in Paris between 2003 and 2011.

Results

Fourteen patients were identified (10 men and four women). Median age at diagnosis was 66.5 years. Twelve patients were diagnosed with AL amyloidosis, one with AA amyloidosis, and one with transthyretin amyloidosis. All patients presented cardiac manifestations: heart failure (n = 9), rhythm disorders (n = 6). Eight patients presented extra-cardiac manifestations of amyloidosis: renal (n = 8), gastrointestinal (n = 5). Troponin serum level was increased in eight patients and BNP level was superior to 400 pg/L in 12 patients. When performed, the cardiac magnetic resonance imaging (MRI) showed, in six patients out of seven, chamber dilatation, concentric hypertrophy or late enhancement. Among patients with cardiac failure at diagnosis (n = 9), seven died with a median survival of 1 month duration. Factors of poor prognosis were, in our study, heart failure, elevated levels of troponin and BNP, and the AL amyloidosis subtype.

Conclusion

Cardiac amyloidosis, especially the AL type, has a very poor prognosis, essentially because of an underlying multiple myeloma and heart failure.     

Mutaciones de la región precore,promotor basal del core y polimerasa viral en pacientes con hepatitis B crónica

Background

Variations of C gene give rise to precore and basal core mutations, which influence HBeAg expression The antiviral treatment failure is due to the presence of variations in the gene P, which cause mutations in the viral polymerase.

Methods

We performed genotyping of HBV P gene by sequencing, and gene C in patients with chronic hepatitis B over a period of five years.

Results

A total of 75 % of the patients had some mutation in precore or in basal core promoter regions, and 37 % demonstrated resistance mutations to antiviral treatment. The most frequent genotypes were A and D.

Conclusions

The presence of mutations in core/precore regions in patients with chronic hepatitis has led to tighter control of these patients. Detecting for resistance should be done as quickly as possible before there is an increase in viral load.     

Prise en charge du purpura thrombopénique immunologique en France avant la mise à disposition des agonistes du récepteur à la thrombopoïétine

Purpose

Adult immune thrombocytopenia (ITP) is an auto-immune disease with most often a chronic course for which a consensual therapeutic strategy is missing. The objective of this study was to describe treatment practices in adult ITP in France before the era of thrombopoietin receptor (TpoR) agonists.

Methods

A retrospective observational study was conducted in eight hospitals in France. All eligible patients were at least 18 years of age and were seen for a chronic ITP between January 2004 and March 2006 in one of the participating centers. Data were collected retrospectively from clinical charts. ITP treatment from disease onset was analyzed for every patient according to the time of diagnosis.

Results

The study included 122 patients (73% of women) with a mean age of 52.6 years. Patients in whom ITP had been diagnosed less than 4 years earlier (n = 71) received on average 2.9 treatment lines. Corticosteroids possibly combined with intravenous immunoglobulins were most often used as a first-line. From the second line, up to 12 different regimens were identified. As a third line, rituximab and splenectomy were the most common therapeutic procedures. The number of splenectomy tended to decrease over time.

Conclusion

This analysis reflects the great heterogeneity into the management of chronic ITP. Whether such heterogeneity has declined after national guidelines have been produced remains to be assessed as well as the place of the newly develop TpoR agonists.
