Résultats à court et long terme du remplacement valvulaire mitral par prothèse mécanique à bille et à ailettes (à propos d’une série de 236 patients consécutifs avec un suivi moyen de 11 ans)

Objectives

To study the early and late results of mitral valve replacement (MVR) by Starr-Edwards caged-ball and bileaflet mechanical prosthesis.

Material and methods

We retrospectively analyzed 236 MVR performed in 236 patients: 127 by Starr-Edwards prosthesis (group 1) and 109 by bileaflet prosthesis (group 2).

Results

During the early period (30 days), the mortality rate was higher in group 1 (6.3 % vs 1.8 %; p = 0.0001), while hemorrhagic, thromboembolic and infectious complications were comparable in the two groups. In the late period (> 30 days) and with an average follow-up of 11.5 ± 5.7 years, mortality was higher in group 1 (9.4 % vs 4.6 %; p < 0.0001). The same was true for thromboembolic complications (20.8 % vs 6.4 %; p < 0.0001), hemorrhagic complications (13.4 % vs 7.3 %; p = 0.02), infectious complications (3.1 % vs 0.9 %; p = 0.02) and cardiac complications that were not due to the prosthesis (32.3 % vs 14.7 %; p = 0.02). The hemodynamic profile of the bileaflet prostheses was better than that of the Starr-Edwards prostheses (average functional prosthetic surface area was 2.37 ± 0.44 cm² and average pressure gradient was 5.6 ± 1.1 mmHg vs 2.04 ± 0.52 cm² and 7.6 ± 4.9 mmHg).

Conclusion

Our work confirms the superiority of bileaflet mechanical prostheses, with rates of early and late mortality, thromboembolic and hemorrhagic complications lower than those of the Starr-Edwards prostheses in more than 11 years of follow-up. However, one should not forget that the prevention of infective endocarditis, good observance of oral anticoagulant treatment and early surgery before left ventricular dysfunction occurs remain the best guarantee a good result of the MVR.     

A randomized trial comparing heparin initiation 6 h or 24 h after pacemaker or defibrillator implantation

OBJECTIVES

The purpose of this randomized study was to evaluate the prevalence of pocket hematomas in patients treated with heparin 6 h or 24 h after pacemaker or defibrillator implantation.

BACKGROUND

The risks of pocket hematoma and need for evacuation after device implantation have not been defined in patients who require anticoagulation.

METHODS

Forty-nine consecutive patients with an indication for anticoagulation with heparin after implantable defibrillator or pacemaker implantation were randomized to receive intravenous heparin either 6 h (n = 26) or 24 h (n = 23) postoperatively. Both groups also received warfarin on a daily basis starting the evening of surgery. Twenty-eight patients who received postoperative warfarin alone and 115 patients who did not receive anticoagulation were followed up in a study registry.

RESULTS

A pocket hematoma developed in 6 of 26 patients (22%) who were treated with intravenous heparin 6 h postoperatively, as compared with 4 of 23 patients (17%) who were treated with intravenous heparin 24 h postoperatively (p = 0.7). In total, a pocket hematoma developed in 10 of 49 patients (20%) treated with heparin, 1 of 28 patients (4%) treated with warfarin alone and 2 of 115 (2%) patients who received no anticoagulation (p < 0.001).

CONCLUSIONS

Intravenous heparin initiation 6 h or 24 h after pacemaker or defibrillator implantation is associated with a 20% prevalence of pocket hematoma formation. Warfarin therapy or no anticoagulation is associated with only a 2% to 4% risk of pocket hematoma formation.     

Facteurs de risque cardiovasculaire chez les travailleurs postés d’une centrale de production d’électricité au centre tunisien

The purpose of the study

The aim of the present study was to investigate relationship between shift work and the cardiovascular risk factors.

Methods

A cross-sectional study was included 330 subjects worked in a company of electricity production in the Centre of Tunisia. The collection of data was based on a questionnaire, a clinical exam and biomarkers.

Results

A total of 290 workers was participated in our study (128 shift workers and 162 daytime workers). A raised prevalence but not statistically significant of some factors of cardiovascular risks was found in the shift workers: obesity (25.8 % versus 17.9 %), smoking (44.5 % versus 39.5 %), impaired fasting glucose (11.7 % versus 9.9 %), hypertriglyceridemia (28.1 % versus 25.9 %) and hypercholesterolemia (14.8 % versus 12.4 %). Whereas the prevalence of the alcohol consumption (25.8 % versus 16.0 %) was significantly higher in the shift workers (p = 0.04).

Conclusion

The high prevalence of the cardiovascular risk factors, observed in our shift workers, justify the adoption of measures to protect this category of workers.     

Safety of pacemaker and implantable cardioverter–defibrillator implantation during uninterrupted warfarin treatment — The FinPAC study

Background

Periprocedural management of oral anticoagulation (OAC) in patients undergoing cardiac rhythm management (CRM) device implantation is controversial. Prior studies demonstrate that uninterrupted OAC may be safe, but limited data from randomized trials exist.

Methods

We conducted a multicenter, randomized trial to evaluate the safety of uninterrupted OAC during CRM device implantation. Patients on long-term warfarin (N = 213) treatment with contemporary indication for CRM device implantation were randomized to uninterrupted versus interrupted (2 days) OAC therapy. The primary outcome included major bleeding events necessitating additional intervention and thromboembolic events during 4 weeks follow-up.

Results

The randomized groups were well matched in terms of bleeding and thromboembolic risk. Only one (1%) patient in the uninterrupted OAC group (N = 106) needed blood transfusion due to rupture of proximal cephalic vein. Large hematomas were detected in 6% of patients in both groups, but there was no need for pocket revision in either group. Any pocket hematoma was observed in 35 patients (33%) in the uninterrupted OAC group and in 43 patients (40%) with interrupted OAC and uninterrupted OAC strategy was non-inferior to interrupted OAC (HR 0.86, 95%, p = 0.001 for non-inferiority). One patient with interrupted OAC had stroke 3 days after the procedure. Hospital stay was comparable in all patient groups.

Conclusion

Our randomized study demonstrates that CRM devices can be safely implanted without discontinuation of warfarin treatment.     

Observance médicamenteuse chez un échantillon d’hypertendus dans la région de Sfax (Tunisie)

The aim of the study

Medication noncompliance is one of the daily problems of the physician. Improving the medication adherence allows better management of hypertension. The aim of this work was to determine the level of compliance for patients with hypertension and to identify factors that determine compliance.

Methods

A cross-sectional study was carried out among a sample of hypertensive patients attending general and specialist practitioners in public or private clinics of Sfax. Two hundred and seventy-three participants had accepted to be interviewed. Patients were identified as noncompliants using a questionnaire developed by the Comité de lutte contre l’hypertension artérielle (CFLHTA).

Results

Non-compliance rate was 63.4%. The low level of education was associated with a lower adherence. The monotherapy, the once-daily regimen with fewer number of tablets were associated with a better adherence (p < 10⁻⁶). The welcome and the availability of drugs in the public clinic affect positively the adherence of patients (p < 0.0002). A patient very satisfied with his consultation and the explanation given by the doctor about his illness and its treatment had a better adherence (p < 0.00003).

Conclusion

Our study had demonstrated a low compliance with antihypertensive drug therapy. Tunisian health care system should elaborate a management plan which takes into account our particular predictors of compliance to improve adherence to antihypertensive medication.     

Corrélation entre les dosages des dérivés methoxylés urinaires et l’index d’apnée-hypopnée dans une population d’hypertendus : étude pilote

Aims

Sleep disorders like obstructive sleep apnea in adults are associated with increased sympathetic activity, which induced high blood pressure and could be associated with resistant hypertension. Some studies have demonstrated that high urinary catecholamine levels in obstructive sleep apnea patients may be decreased with continuous positive airway pressure therapy. However, very few studies have demonstrated a correlation between apnea-hypopnea index and urinary catecholamine levels in hypertension patients.

Methods

In this pilot study, 20 hypertensive patients referred for hypertension work-up including night-time polygraphy and 24 h urinary catecholamine dosage were included.

Results

Mean age was 51 ± 11 years (30–76), 68% were males. Diagnosis of obstructive sleep apnea was confirmed in 13 patients at the end of the work-up. Mean apnea-hypopnea index was 14 ± 9 (2–32). The only urinary catecholamine parameter significantly increased in patients with obstructive sleep apnea was 24 h urinary normetanephrine (1931 ± 1285 vs 869 ± 293 nmol/24 h; P < 0.05). However, this difference was not significant when this parameter was adjusted to 24 h urinary creatinine. We observed a significant positive correlation between AHI and 24 h urinary normetanephine (r = 0.486; P = 0.035).

Conclusion

This pilot study confirms an isolated elevation of 24 h urinary normetanephrine in hypertensive patients with obstructive sleep apnea and shows a significant correlation between sleep disorders expressed by apnea-hypopnea index and urinary catecholamines excretion.     

Anévrismes infectieux de l’aorte. À propos d’une série de dix patients

Purpose

Infectious aortic aneurysms are rare, being responsible of less than 3% of aortic aneurysms. In this study, we report the clinical characteristics and the outcome of patients presenting with infectious aortic aneurysms in an internal medicine unit.

Methods

Diagnosis of infection-related aortic aneurysm was obtained using: computed tomographic scan; and blood cultures, cultures and molecular biology testing of aortic wall and intra-aneurismal thrombus.

Results

The 10 consecutive patients included in this study consisted in eight men and two women with a mean age of 61.7 years. Patients presented with fever (n = 9), asthenia (n = 2), abdominal (n = 4) or chest pain (n = 1), lumbar pain (n = 3). Computed tomographic scan showed aneurysm involving both thoracic and abdominal aorta (n = 1), abdominal (n = 8) or thoracic aorta (n = 1). Isolated microorganisms were: positive Gram cocci (70%) and negative Gram bacilli (30%). All patients underwent both medical and surgical therapy. Outcome was favorable in nine patients; the remaining patient died from aneurismal aortic rupture.

Conclusion

Clinical manifestations revealing infectious aortic aneurysms are variable, including aneurysm rupture as well as atypical abdominal pain with inflammatory syndrome. These latter presentations are more common in patients, who are hospitalized in internal medicine. Our study underlines that this clinical pattern should not be ignored, in order to avoid both diagnostic and therapeutic delay that could lead to life-threatening complications and poor prognosis.     

Intérêt d’un nouveau protocole de cytomètrie en flux appliqué au diagnostic et à la prévention des accidents peranesthésiques aux curares

Aim of the study

We tested here a new cytometric method based on the use of two activation markers (CD63 and IgE) and result's expression in activation index (AI).

Material and methods

Twenty-six allergic patients and 23 controls having received a neuromuscular blocker (NMB) have been selected on the basis of clinical history, skin tests and specific IgEs. NMB were tested mixed (n = 26) or alone (injectable form, (n = 30) and allergens commercialized for flow cytometry (n = 9)). Concentrations used were the same than for IDR according to the recommandations of the French Society of Anaesthesia and Resuscitation (SFAR). The cytometric protocol used was the IgE/CD63 protocol, results being expressed in percentage CD63 and in AI calculated by a specific algorithm involving the mean fluorescence intensity (MFI) of the IgE+ and the CD63+ and − populations.

Results

In the technical described here NMB exhibited no toxicity even for concentretions 10 times higher than concentrations used for diagnosis. With the injectable form, the respective sensitivities observed for CD63 alone and the AI were 68 and 100% for the mixture of NMB and, 67 and 100% for the isolated NMB. With the NMB commercialized for flow cytometry, sensitivities were 47 and 100%. Specificities were 100% for CD63 alone and 98% for the AI. The link (Chi²) between skin tests and flow cytometry was significant for the two markers and the two allergen types. Correlation between AI and specific IgEs was not significant.

Conclusion

The new flow cytometric protocol described here has the necessary characteristics of a biological test which could be included in the pre-anaesthetic check up.     

Oral anticoagulation doesn't increase hemorrhagic risk in patients undergoing a cardiac pacemaker or defibrillator implantation

Objectives

This study was designed to assess the hypothesis that the implantation or the replacement of a cardiac stimulator or defibrillator in patients receiving oral anticoagulants with an INR ≥ 2 doesn’t increase the hemorrhagic risk in comparison with patients for whom the treatment has been interrupted temporarily (INR < 2) or with patients not receiving anticoagulants (control group).

Patients and results

We performed a retrospective chart review of bleeding complications in all patients undergoing pacemaker or ICD implantation or replacement between January 2007 and may 2009. In this cohort, 43 patients (10%) were implanted with an INR ≥ 2 while 36 patients (8%) were implanted with an INR < 2 and 352 patients (82%) didn’t receive anticoagulants. No complication (0/36) has been observed in patients having an INR < 2, while 3/43 (7%) complications have been observed in patients with an INR ≥ 2 and 13/352 (3.7%) in patients in the control group (p = 0.3093). Duration of the hospital stay was similar in the three groups: 6.2 days in patients with an INR < 2, 6.8 days in the group with an INR ≥ 2 and 6.2 days in the control group (p = 0.686).

Conclusion

Pacemaker and ICD implantation or replacement without withdrawing of oral anticoagulants and an INR ≥ 2 was not associated with an increase of the hemorrhagic risk.     

Association d’une hypertension artérielle rénovasculaire et d’un hyperaldostéronisme primaire

Introduction

Renal artery stenosis is rarely associated with Conn adenoma.

Case report

We report a 27-year-old male patient who presented in 2001 with a severe high blood pressure associated with hypokaliemia. Radiologic investigations showed a left renal artery stenosis with agenesis of left kidney. A left nephrectomy was performed and blood pressure returned to normal with a single antihypertensive drug. Five years later, the patient again presented with severe high blood pressure. Laboratory studies revealed a low serum potassium level at 2.8 mmol/L associated with high urinary potassium excretion (84 mmol/24 h) and a very high aldosterone/renin ratio (> 462). Abdominal CT scan demonstrated a right adrenal mass. The patient underwent a right adrenalectomy (adenoma). Blood pressure returned to normal with a single antihypertensive. Serum potassium levels as well as aldosterone/renin ratio normalized.

Conclusion

We discussed whether the association between these two entities is merely fortuitous or conversely based on a causal relationship.     

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.     

Altération de la variabilité sinusale chez les malades en hémodialyse chronique

Background and aim

Decrease in heart rate variability (HRV) is a known risk factor for cardiovascular morbidity and mortality. The aim of our study is to evaluate HRV in chronic hemodialysis patients and to determine factors that might decrease or increase it.

Methods

This is a retrospective study including 51 patients, 23 males and 28 females, with a mean of age of 64.5 years (23-84 years) on chronic hemodialysis for end stage renal disease due to various causes. Twenty-four-hour heart rate monitoring was recorded in all patients to evaluate HRV. HRV of hemodialysis patients was compared to normal patients (control). We also looked for correlation between HRV and a number of clinical and biological factors.

Results

All HRV parameters were decreased in chronic hemodialysis patients compared to normal controls with a significant difference (p < 0.0005). HRV decreases with age (p = 0.012), and is lower in diabetic patients (p = 0.026). Interestingly, we found that chronic hemodialysis patients on beta-blockers had higher HRV with p = 0.011.

Conclusion

HRV is reduced in chronic hemodialysis patients mainly in old and diabetic patients, but this decrease is less important in those receiving beta-blockers.     

Long-term Effect of Chronic Oral Anticoagulation with Warfarin after Acute Myocardial Infarction

Background

Antiplatelet therapy is the principal component of the antithrombotic regimen after acute myocardial infarction. It remains unclear whether additional chronic oral anticoagulation (OAC) improves outcomes. We set out to evaluate the risk and benefit of long-term OAC after myocardial infarction.

Methods

We pooled 10 randomized clinical trials comparing warfarin-containing regimens (OAC) with or without aspirin with non-OAC regimens with or without aspirin (No OAC) for patients with recent infarction. The primary endpoint was all-cause mortality. Other endpoints included recurrent infarction, stroke, and major bleeding. We calculated the odds ratio (OR) (fixed effect, OR <1 indicates benefit for OAC) for death and other ischemic and hemorrhagic complications at the longest interval of follow-up available.

Results

Among 24,542 patients, 14,062 were assigned to OAC and 10,480 to no OAC. The patients were followed for 3-63 months, for 89,562 patient-years. Death occurred in 2424 patients (9.9%), 1279 OAC patients, and 1145 in the no OAC group, OR 0.97 (95% confidence interval [CI], 0.88-1.05), P = .43. Similarly, there was no effect on recurrent infarction. Stroke occurred in 578 patients (2.4%), 271 in the OAC group and 307 in the no OAC group, OR 0.75 (95% CI, 0.63-0.89), P = .001. There was substantially more major bleeding (OR 1.83 [95% CI, 1.50-2.23], P <.001) in the OAC group. Separate analyses, performed for patients (n = 11,920) randomized to aspirin versus aspirin and OAC yielded very similar results.

Conclusion

As compared with placebo or aspirin, OAC with or without aspirin does not reduce mortality or reinfarction, reduces stroke, but is associated with significantly more major bleeding.     

Sclérites,aspects cliniques, étiologiques et thérapeutiques : à propos d’une série de 32 observations

Purpose

To report on the various clinical presentations, etiological diagnosis, prognosis and treatment of patients with scleritis evaluated at a tertiary care eye center.

Methods

Retrospective, monocentric study on a series of 32 patients in a tertiary center.

Results

The mean age of included patients with scleritis was 46.8 years (range, 22 to 77 years). Nineteen patients were women and 13 were men. Twenty-six patients (81%) had anterior scleritis (15 nodular, 8 diffuse and 3 necrotizing), six (19%) had posterior scleritis. Unilateral inflammation was present in 24 patients (75%). Twelve out of the 32 patients (37.5%) had an underlying systemic disease: granulomatosis with polyangiitis (n = 3), Behçet's disease (n = 2), unspecified inflammatory arthritis (n = 2), psoriatic arthritis (n = 1), ankylosing spondylitis (n = 1), sarcoidosis (n = 1), Cogan's syndrome (n = 1) and ulcerative colitis (n = 1). Six patients (18.8%) were suspected of having infectious disease with herpes virus: clinical context and positive treatment response with oral valacyclovir. Systemic agents and topical agents were required in 28 patients (87.5%). The first line therapy was mainly oral non-steroidal anti-inflammatory drugs in 15 patients (47%) and oral corticosteroids in 8 (25%). Immunosuppressive drugs were required in 6 patients. The mean follow-up was 16.3 months. Six patients (19%) had a decrease in visual acuity.

Conclusion

The number of systemic disease in our series is similar to the main series in the literature. Treatment with valaciclovir might be effective in patients with suspected herpes simplex scleritis.     

Étude électrophysiologique par voie transœsophagienne chez des enfants de moins de 11 ans, non sédatés, ayant un syndrome de Wolff-Parkinson-White

The electrophysiological evaluation of Wolff-Parkinson-White syndrome (WPW) is recommended in children aged more than five years to detect a risk of life-threatening arrhythmia. The purposes of the study were to determine the feasibility of transesophageal EPS in a child between six and 10 years in out-patient clinic.

Methods

Electrophysiological study (EPS) was indicated in 22 children, aged six to 10 years, with a manifest WPW either for no documented tachycardia (n = 7), unexplained dizziness (n = 2) or for a sportive authorization in 10 asymptomatic children. Two of the last children had a history of permanent tachycardia after the birth but were asymptomatic since the age of one year without drugs.

Results

EPS was performed in all children. The main difficulty lied in passing the catheter through the mouth. Programmed stimulation at cycle length of 380 ms was performed in all children to avoid high rates of pacing when the conduction through the accessory pathway (AP) and normal AV system was evaluated. Isoproterenol was not required in five children, because they developed a catecholaminergic sinus tachycardia. The AP refractory period was determined in all children between 200 and 270 ms. Orthodromic reentrant tachycardia (RT) was induced in 11 children, three asymptomatic children (27%), seven complaining of tachycardia and one with syncope. Rapid antidromic tachycardia was induced in this last child with dizziness. Atrial fibrillation was never induced.

Conclusions

Esophageal EPS can be performed without sedation in a young child six to 10-year-old with a shortened protocol of stimulation, which was capable to clearly evaluate the WPW-related risks.     

Valeur prédictive comparée de mortalité hospitalière du peptide natriurétique de type B et de l’albuminémie chez le sujet âgé hospitalisé pour insuffisance cardiaque aiguë sévère

Objective

To address the clinical relevance of serum albumin and B-type natriuretic peptide (BNP) concentration in the prediction of in-hospital death in elderly patients with acute severe heart failure.

Patients and methods

Seventy-four consecutive patients >70 years of age admitted for acute heart failure in NYHA class IV were prospectively included. BNP concentration was measured on admission and serum albumin concentration after clinical stabilization.

Results

Mean age was 86.6 ± 5.7 years. Sixty-five percent of patients had a normal left ventricular ejection fraction. Eighteen patients died during the in-hospital stay. Those patients who died were older, had higher blood urea nitrogen and BNP concentration, had lower systolic blood pressure and serum albumin concentration than patients who survived. Heart rate, rhythm, left ventricular ejection fraction, serum creatinine and hemoglobin did not differ according to outcome. By multivariate analysis, albumin (p = 0.0017), BNP (p = 0.016) and age (p = 0.03) were independent predictors of in-hospital death. Serum troponin I measured on admission in 71 patients was predictive of in-hospital death (p = 0.01), as well as serum total cholesterol measured after stabilization in 66 patients (p = 0.004). However, these two variables no longer predicted outcome in multivariate models, unlike serum albumin and BNP.

Conclusion

Serum albumin and BNP offer independent, additional information for the prediction of in-hospital death in elderly patient with acute severe heart failure regardless of left ventricular ejection fraction.     

Myopathies inflammatoires et anticorps anti-PM-Scl : à propos d’une série et revue de la littérature

Purpose

The objectives of this study were to evaluate: (1) the prevalence of anti-PM-Scl antibodies within the framework of antinuclear antibodies detection; and (2) the clinical features and outcome of patients with isolated polymyositis/dermatomyositis.

Methods

Nine thousand and sixty-four consecutive antinuclear testing data allowed us to evaluate anti-PM-Scl antibody prevalence. Second, we also assessed the characteristics of patients with isolated dermatomyositis/polymyositis and associated anti-PM-Scl antibody.

Results

Over 9064 consecutive antinuclear samples tested for antinuclear antibodies, 3263 (36%) were positive; anti-PM-Scl antibody were positive in nine patients: 0.1% of all sera, 0.2% of sera positive for antinuclear antibodies, 1.2% of sera positive for anti-ENA antibodies. Four of the nine patients with anti-PM-Scl antibody had dermatomyositis (n = 3) and polymyositis (n = 1). Patients with dermatomyositis/polymyositis and anti-PM-Scl antibody exhibited severe complications, as follows: ventilatory insufficiency (n = 2) requiring mechanical ventilation in one case, esophageal involvement requiring enteral feeding (n = 1); also, two of these patients had cancer.

Conclusion

Our case series suggests that the presence of anti-PM-Scl antibody is not a favorable prognostic factor in patients with dermatomyositis/polymyositis. This type of antibody appears to be associated with lung and esophageal involvement; in addition, anti-PM-Scl antibody may co-exist with malignancy in PM/DM patients. Taken together, we suggest that patients with dermatomyositis/polymyositis and anti-PM-Scl antibody require both initial evaluation for lung/digestive manifestations and cancer and close surveillance.     

La pancréatite lupique : une série de six cas

Purpose

The occurrence of acute pancreatitis in systemic lupus erythematosus (SLE) is known but rare, and is exceptionally the presenting manifestation. Its pathogenesis is multifactorial, and it is difficult to separate what belongs to vasculitis, thrombotic phenomena in the context of an associated antiphospholipid syndrome, or iatrogenic complications. We report on six cases of lupus pancreatitis.

Methods

This is a retrospective monocenter study of 110 patients with SLE. The diagnosis of lupus pancreatitis was established after exclusion of other causes of pancreatitis.

Results

Five women and one man (5.4%) with a mean age of 36.3 years presented with lupus pancreatitis. In four patients the pancreatitis was concurrent with the diagnosis of SLE and it occurred later during an exacerbation of the disease in the two remaining patients. In all patients, pancreatic manifestations were associated with other organ involvement. Clinical manifestations were: abdominal pain (n = 6), vomiting (n = 3), and fever (n = 3). Elevated pancreatic enzyme was noted in all cases. All patients were treated by high doses of glucocorticoids. The outcome was favorable in five patients, and one patient died.

Conclusion

Pancreatitis may be the presenting manifestation of SLE. Its pathogenesis is often multifactorial. The outcome is usually favorable with corticosteroids.     

Corrélations entre antécédents d’angioplastie coronaire et mortalité précoce après chirurgie coronaire

Background

In this study, we examine the effect of previous percutaneous intervention on the rate of adverse perioperative outcome in patients undergoing coronary artery bypass graft surgery (CABG).

Methods

Outcomes of 240 CABG patients, collected consecutively in an observational study, were compared. Gp A (n = 35) had prior PCI before CABG and Gp B (n = 205) underwent primary CABG.

Results

Statistically significant results were obtained for the following preoperative criteria: previous myocardial infarction: 48.6% vs 36.6% (P = 0.003), distribution of CAD (P = 0.0001), unstable angina: 45.7% vs 39% (P = 0.04). For intraoperative data, the total number of established bypasses was 2.6 (GpA) vs 2.07 (Gp B) (P = 0.017), with the number of arterial bypass grafts being: 20% vs 13% (P = ns). Regarding the postoperative course, no significant difference in troponine I rate, 24-hour bleeding: 962 ml (Gp A) vs 798 ml (Gp B) (P = 0.004), transfusion (PRBC unit): 3.63 (Gp A) vs 2.5 (Gp B) (P = 0.006). Previous PCI emerged as an independent predictor of postoperative in-hospital mortality (OR 2.24, 95% CI [1.52–2.75], P < 0.01).

Conclusion

Patients with prior PCI presented for CABG with more severe CAD. Thirty-day mortality and morbidity were significantly higher in patients with prior PCI.
