Lupus hepatitis: a case series of 12 patients

Purpose

Several liver manifestations have been reported in systemic lupus erythematosus (SLE) and are usually non specific. We report on our experience of lupus hepatitis.

Methods

A retrospective monocenter study of 73 patients with SLE. The diagnosis of lupus hepatitis was established after exclusion of other causes of hepatitis and hepatic vein thrombosis.

Results

Liver involvement was noted in 12 patients (16.4%). There were nine female and three male patients; the mean age of these patients was 29 years. In seven patients liver involvement was concurrent with the diagnosis of SLE and it occurred later during an exacerbation of the disease in the five remaining patients. In all patients, liver manifestations were associated with other organ involvement. Clinical manifestations were: hepatomegaly (n = 4), jaundice (n = 4), abdominal pain (n = 3), ascitis (n = 2), portal hypertension (n = 1) and hepatic failure with encephalopathy (n = 1). Elevated liver enzyme was noted in 11 cases and liver cholestasis in eight cases. Presence of anti-ribosomal P antibodies was noted in one case. Liver biopsy was performed in five patients, and revealed chronic active hepatitis in three cases, chronic hepatic granulomas in one case and nonspecific inflammation in one case. The outcome was favorable in 11 patients without relapse, and one patient died of encephalopathy and liver failure.

Conclusion

Liver involvement associated with SLE is not uncommon. It is frequently asymptomatic and limited to liver test abnormalities. The role of anti-ribosomal P autoantibodies remains uncertain.     

Renal sarcoidosis: a series of five patients

Introduction

Renal involvement is uncommon in sarcoidosis, occurring in less than 5% of the patients. Diagnostic delay should be minimal to improve the outcome.

Methods

From 1996 to 2009, 78 patients were seen for sarcoidosis in the Department of Internal Medicine of Rouen University hospital.

Results

Five patients (6.4%) had renal involvement. Diagnosis of renal involvement and sarcoidosis were concomitant in two patients while in the three remaining patients, renal manifestations occurred during the course of sarcoidosis. The five patients with renal manifestations exhibited: isolated sarcoid granulomatous interstitial nephritis (n = 2), sarcoid granulomatous interstitial nephritis and nephrocalcinosis (n = 2), renal failure due to hypercalcemia (n = 1).

Conclusion

This series underlines that renal function tests should be performed systematically both during initial evaluation and the follow-up of patients with sarcoidosis.     

Immune profile of elderly patients admitted in a geriatric short care unit

Introduction

Immunosenescence embraces the whole of age-induced changes observed in the immunomodulatory functions of a living organism, and is mostly characterized by a decrease in cell-mediated immunity and important modifications of the immunological repertoire. The impact of the pathology on ageing immunity is poorly understood and few data are available on the immunological status of old polypathological patients.

Methods

We report the results of a prospective study aiming at characterizing several established immunological parameters in patients of 75 years old or more, and admitted for diverse pathologies in a unit of acute geriatric ward.

Results

Among the 51 included patients (35 women and 16 men), 90% displayed poly-pathologies. We found a prevalence of 86% of immunological abnormalities, with lymphopenia among 41% of the patients (<1500/mm³) and abnormal lymphocytes phenotypes among 95% of the oldest patients (>85 years). A strong skewing towards memory T lymphocytes (CD45RO+) over naive T lymphocytes (CD45RA+) was found in 80% of the cases and inverted CD4/CD8 T cells ratio was observed in 12% of our patients. Vitamin D insufficiency (<30 ng/ml), which is frequent among the patients (94%), is a predictive factor for T and B cell lymphopenia.

Conclusion

Immunological abnormalities are frequent in this frail population and lymphopenia, in particular, could constitute a reinforcing factor of fragility. Vitamin D deficiency could also affect elderly patients’ immunity.     

Etiology and prognosis of highly elevated C-reactive protein levels (≥500 mg/L): a retrospective study about 168 measures in a series of 113 patients

Purpose

The C-reactive protein (CRP) is a useful inflammatory marker with a rapid kinetics during the inflammatory process. The objective of this study was to determine the etiology and prognosis of extremely elevated CRP values greater or equal to 500 mg/L.

Methods

We performed an exhaustive retrospective study from January 2004 to July 2009, in a general hospital, of all patients with a CRP value above 500 mg/L, admitted in all clinical departments. Clinical data were collected by a single observer using a standardized questionnaire.

Results

One hundred and sixty-eight CRP values greater or equal to 500 mg/L were identified amongst 106,758 tests (0.16%) corresponding to 113 patients: 51% were men and their mean age was 59.5 years. Mean CRP value was 561 mg/L (500-772). An immunocompromised condition was observed in 52% of the patients. All but 13 patients presented an infectious disease. Microbiological analysis of the infected patients identified 59 Gram-positive cocci (20 Staphylococcus spp., 35 Streptococcus spp. including 21 Streptococcus pneumoniae), two Gram-negative cocci, 48 Gram-negative bacilli (including 19 Escherichia coli), three Gram-positive bacilli, 16 fungal infections, one viral infection. Site of infection was respiratory in 63%, urinary in 17% and abdominal in 16%. At day 30, mortality rate was 27% and only 41% of the patients were discharged at home.

Conclusion

CRP value above 500 mg/L is highly related to bacterial infections, without over-representation of a given microorganism. One-month mortality is high (27%).     

Durée de traitement des tuberculoses extrapulmonaires : six mois ou plus ? Analyse de la base de données TB-INFO

Purpose

The recommended duration of pulmonary tuberculosis therapy is 6 months. For extrapulmonary tuberculosis, treatment duration depends on tuberculosis involvement and HIV status. The objective of this study was to describe the main characteristics of a cohort of extrapulmonary tuberculosis patients, to compare patients with a 6-month treatment to those with more than a 6-month treatment, and to analyze the compliance of medical centres with recommended duration of treatment.

Methods

A retrospective cohort study of 210 patients with extrapulmonary tuberculosis was carried from January 1999 to December 2006 in two hospitals in the north-east of Paris. These patients were treated with quadruple therapy during two months, followed by dual therapy during 4 months (n = 77) or more (n = 66). The characteristics of each group were compared by uni- and multivariate analysis. The primary endpoint was the rate of relapse or treatment failure at 24-month follow-up after treatment completion.

Results

No relapse was observed after 24 months of follow-up after the end of treatment in the two groups. In univariate analysis, patients with lymph node tuberculosis were more often treated for 6 months than at other sites of tuberculosis (respectively 61% versus 40.9%; P = 0.02); the decision of treatment duration was related to medical practices (79.2% treated 6 months in one hospital versus 20.7% in the other, P < 0.001); patients living in private residence were more often treated during 6 months than patients living in residence (24.2% versus 10.3%, P = 0.042). In multivariate analysis, only hospital (P = 0.046), sex (P = 0.007) and private residence were significantly different in each group.

Conclusion

A period of 6 months seems to be sufficient to treat extrapulmonary tuberculosis (except for neuromeningeal localization).     

Influence de la fonction rénale sur la pertinence diagnostique du BNP chez l’insuffisant cardiaque âgé

Aim of the study

BNP levels are accurate in the diagnosis of heart failure and useful in clinical practice. Relationship between BNP, heart failure (HF) and renal function are little known in the elderly. Renal function influence the optimal cut point of BNP in patients with a Glomerular Filtration Rate (eGFR) lesser than 60 ml/min/1.73 m².

Methodology

A total of 71 patients (mean age = 85 years) were admitted in a Cardiogeriatric Unit. We noted several parameters, age, gender, the presence or the absence of Systolic Heart Failure (clinical history and physical examination), the echographic measure of the left ventricular ejection fraction, the eGFR value calculated by simplified MDRD formula and the BNP value. We divided these patients into six groups according the presence of HF and eGFR value higher than 60ml/min/1.73m²,or between 30 and 60 or between 15 and 30.

Results

Our results show that the BNP value is higher in all the three groups of patients with Heart Failure with or without diminution of the eGFR: for example, 1220 pg/ml in the presence of HF versus 788 pg/ml in the absence of HF in the two groups with the eGFR is calculated between 15 and 30 ml/min/1.73m².

Conclusion

BNP is a helpful tool in clinical practice for the diagnosis of Systolic Heart Failure in the presence of renal impairment in the elderly with a higher biomarker cut point.     

La sténose radique de l’artère rénale : une complication inhabituelle de la radiothérapie

Introduction

Renal artery stenosis represented 1 to 5% of all arterial hypertensions and is the leading cause of secondary hypertension. Renovascular hypertension is more common among women less than 30 years old (fibrodysplasia, 33%) and men older than 50 years old (66% atherosclerosis). Other causes are rare, especially radiation-induced renal artery stenosis.

Materials and methods

We report the case of Mr. D., 49 years old, with severe high blood pressure (230/125 mmHg) seven years after abdominal radiotherapy for Hodgkin's disease. Echo-Doppler was performed and found a subocclusive right ostial renal artery stenosis probably radiation-induced taking into account the history of the patient. Renal angiography confirmed this diagnosis and percutaneous transluminal renal artery angioplasty was performed with a final acceptable result (residual stenosis < 50%).

Discussion

Radiation-induced renal artery stenosis is rare (0.5/1000 to 1%). Most of the cases are proximal and the median time from radiation to referral is nine years. Radiation-induced nephritis disease was often referred to occurrence high blood pressure after abdominal radiotherapy but various data shows that radiation can also cause damage to larger vessels sizes (such as renal arteries) induced by atherosclerosis radiation. Patients should be successful treated by percutaneous intervention, as demonstrated by Fakhouri et al. [Am J Kidney Dis 38 (2001) 302-309] in a study of 11 patients.

Conclusion

This case shows that radiation-induced renal artery stenosis may occur many years after initial treatment, and patients developing severe arterial hypertension after abdominal radiation should be investigated for renal artery stenosis.     

Aspects cliniques et étiologiques des uvéites : étude rétrospective de 121 patients adressés à un centre tertiaire d’ophtalmologie

Purpose

Uveitis consists of a large group of diseases characterized by intraocular inflammation involving the uveal tract. This heterogeneity makes the diagnosis and the treatment of uveitis frequently challenging. The purpose of this study was to describe the various clinical and etiologic aspects of uveitis, through the new standardized uveitis classification and the use of modern investigations for its diagnostic work-up.

Methods

The medical records of 121 new patients with uveitis referred to our tertiary ophthalmologic centre between January 2002 and December 2006 were retrospectively reviewed. Uveitis associated to human immunodeficience virus and secondary to exogenous endophthalmitis were excluded. All patients had a complete ophthalmological examination and appropriate clinical and paraclinical examination. The diagnosis was established according to the recent international criteria.

Results

One hundred and twenty-one patients were included. The four main etiologies were: toxoplasmosis (14%), sarcoidosis (11.6%), spondylarthritis or HLA B27-associated uveitis (13.2%) and Herpes virus infections (9.1%) that represented almost half of the uveitis causes (47.9%). Various diseases constituted the remaining causes of the uveitis (20.9%). Uveitis remained unexplained in the remaining 36 patients (29.7%). Overall, associated systemic diseases were diagnosed in 35.5% of our uveitis patients (34 patients), associated infectious conditions in 26.4% (32 patients) and specific ocular diseases in 8.3% (12 patients).

Conclusion

Despite a limited number of patients, our study showed an etiologic distribution similar to that of the main series reported in the literature. Nevertheless, we observed an elevated frequency of sarcoidosis and systemic diseases, which emphasizes a management that takes into account standardized clinical and paraclinical criteria and the usefulness of a collaboration with the internist.     

Upper digestive bleedings after cardiac surgery

Introduction

Upper gastrointestinal haemorrhage (UGH) following cardiac surgery is infrequent with high mortality. The aim of this study is to compare the frequency and outcome of UGH in patients who had undergone open heart surgery at our institution.

Patients and methods

From January 1994 to December 2005, 1278 cardiac operations were performed. A systematic prophylaxis antiacid was used by antagonists of histaminic receptor (anti-H2, ranitidine 150 mg/12 h) in all patients. The diagnosis was based on clinical symptoms (haematemesis and/or melaena) in the postoperative period and confirmed by fibroscopy. We conducted a retrospective study of these patients.

Results

Only 8 of the 1278 (0,6%) cardiac operations were complicated by UGH. Demographic data were reported in Table 1. The mean interval between surgery and UGH was 10 ± 3,7 days (range 5,15 days). Gastro-duodenal ulcer was the most common cause of UGH in 5 patients (62%), ulcero-hemorrhagic eosophagitis was developed in one patient (12,5%), candidosic eosophagitis in one and multiple gastric ulcer in one patient (12,5%). Medical treatment was applied in 6 patients (72%) with successful result. Surgical intervention was necessary in 2 patients (25%). 2 patients had repeat gastrointestinal bleeding. One patient was died; he was recorded as having severe sepsis and multiple organ failure in addition to UGH.

Conclusion

UGH in patients undergoing heart operation is rare but associated with poor prognosis despite antiacid prophylaxis. These complications occurred in patients who had in postoperative bad hemodynamic conditions.     

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.     

Cerebral revascularisation in Takayasu's arteritis

Subject

Supraaortic angioplasty is often not feasible in patients with Takayasu's arteritis because of involvement of long segment of arteries. Consequently, the role of surgical treatment in the management of cerebral ischemia is important in this disease. The objective of this work is to specify the indications and surgical techniques in lesions of arteries to the head in this disease and to report our experience.

Methods

Seven patients with cervical arterial lesions due to Takayasu's arteritis were treated by bypass surgery in the department of vascular surgery, Ibn-Sina hospital on one period of 11 years.

Results

It is about 6 women and one man of middle age at the time of the diagnosis of 33,8 years. The revealing signs were essentially of neurological and ocular order. Six of our patients were in inflammatory thrust at the time of the diagnosis, and required a medical treatment first to basis of corticosteroids. Bypasses from the ascending aorta to the carotid artery were performed in six cases. In one case, the bypass was performed between the brachiocephalic artery and common carotid artery. A death in relation with a cerebral hemorrhage occurred 2 days after the revascularisation. A clean improvement of the functional signs was noted among 3 patients, whereas the improvement was partial at two other. A secondary thrombosis of the bypass surgery occurred in 3 cases.

Conclusion

The natural history of Takayasu's arteritis and its evolution is badly known. The operative indications must not rest solely on the only anatomical balance, but based on a bundle of arguments in which, the assessment of the cerebral blood flow would be useful. Cerebral hyperperfusion syndrom constitutes a major risk that can be reduced by staged revascularisations.     

À propos des urgences cardiovasculaires au cours des évacuations médicales héliportées réalisées par la Marine Nationale, au large des côtes du Finistère. Étude rétrospective de 2000 à 2007

Background

Search and rescue helicopters from the French navy conduct ambulance and search and rescue missions near the western coast of the French Britain. The team on board includes military doctor and paramedic. Operations in this area are challenging due to long distances and severe weather conditions.

Methods

We studied retrospectively 205 search and rescue missions from 2000 to 2007 with special emphasis on acute heart disease and operative conditions.

Results

12.2% of the missions (25/205) concern acute heart disease dominated by myocardial infarction elevation myocardial infarction. All of the patients are male. Most of them are seafarers and the others come from ferries with a median age of 53.4 years. Sixty-two percent of the missions were carried in darkness. The median range is about 80 nautical miles. Two patients died during search and rescue missions. All patient are hospitalized.

Conclusion

Ambulance and search and rescue mission near the western coasting of the French Britain are a challenge. Using a heavy helicopter from French Navy was the best way to carry medical treatment to seafarers and passengers of ferries suffering from acute heart disease.     

N-methyl-d-aspartate receptor antibody encephalitis: a treatable disorder involving B-lymphocytes. A report of two patients

Introduction

N-methyl-D-aspartate receptor antibody (anti-NMDA-r AB) encephalitis has been recently identified. We report two cases illustrating the clinical features, response to immunomodulatory treatment and involvement of B-lymphocytes that characterizes this disorder.

Case reports

These patients illustrated the classic clinical features of anti-NMDA-r AB encephalitis including occurrence in young female, presence of severe neurological and psychiatric manifestations with confusion, seizures, mutism, hypovigilence and involuntary movements, and inflammatory cerebrospinal fluid. Both patients improved after immunotherapy. In case 1, the encephalitis was associated with an ovarian teratoma containing neuronal elements. In case 2, there was no tumor identified. A brain biopsy showed prominent perivascular B-cells infiltrates with some T-cells distributed in the brain parenchyma.

Conclusion

Anti-NMDA-r AB encephalitis is certainly not rare and needs to be promptly recognized and treated. An associated neoplasia is inconstant and the pathophysiology involves humoral immunity.     

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.     

Longitudinal myelitis in systemic lupus erythematosus

Introduction

Myelitis occurs in less than 5% of the patients during the disease course of systemic lupus erythematosus (SLE). Longitudinal myelitis, characterized by inflammatory involvement of at least four medullar segments, is a particular form of myelitis.

Case report

We report a 31-year-old woman with SLE, admitted for paraparesia and delirium. Lumbar puncture and MRI led to the diagnosis of longitudinal myelitis. The patient rapidly improved after corticosteroid therapy.

Conclusion

Transverse myelitis in SLE patients has been already commonly reported, but longitudinal myelitis is uncommon. Longitudinal myelitis has to be suspected in case of paraplegia or tetraplegia, with sensory defects and bladder dysfunction. MRI shows typically T2 medullar hypersignals. This may result in neurologic sequela. Cyclophosphamide has been used in patients where corticosteroids were inefficient.     

Serious hemorrhages related to vitamin K antagonist treated by prothrombic complexes: retrospective study conducted in 2008

Purpose

Vitamin K antagonist are widely used and clearly useful in the prevention of thrombotic and embolic events. However, they expose to hemorrhagic risk. The aim of this retrospective study was to describe the serious hemorrhagic events that occurred in patients treated with vitamin K antagonist and that required administration of prothrombotic complexes concentrates.

Methods

A comparative analysis of the file of the central pharmacy (that dispensed the prothrombotic complexes concentrates) and patient data of the department of medical information was perform to ascertain the population of patients having received some prothrombotic complexes concentrates. Then, hospitalization reports were consulted to select the patients having presented a severe bleeding while receveiving vitamin K antagonist. We collected patients’ characteristics, bleeding location, INR values, emergency care, seriousness and medical issue. Imputability was determined with the French method of pharmacovigilance.

Results

In 2008, in Caen University hospital, 80 patients received prothrombotic complexes concentrates in the context of a serious hemorrhage due to vitamin K antagonist. Their mean age was 75 years and the most common presentation was a neurological hemorrhage (38,7%). For 63,8% of the patients, there was an overdose in vitamin K antagonist. Twenty-two patients died during their hospitalization and 10 others presented later sequelas. None of the patients included in this study had been spontaneously declared to the pharmacovigilance. High imputability scores were positively correlated with INR (P = 0.0002).

Conclusion

Quality of emergency care of hemorrhagic events due to vitamin K antagonist could be improved with a better application of the professional recommendations and a spontaneous declaration to pharmacovigilance.     

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.
