Late Post-Dissection Dynamic Intermittent Malperfusion of the Aortic Arch in Association with a Rare Heterogenous LOX Gene Variation

Late ischaemic consequences of type A aortic dissection are rare. We present a 6-year late complication of type A aortic dissection treated by Bentall surgery in a 41-year-old patient. The patient presented with several episodes of lipothymia associated with hypertensive attacks with anisotension, cervicalgia, hemicranial headache, abdominal pain and lower limb slipping initially on exertion and later at rest. On dynamic examination, we diagnosed an intermittent dynamic occlusion of the aortic arch and rare LOX gene variation, which is considered to be associated with aneurysm or dissection of the ascending aorta in young patients. Surgical treatment by replacement of the ascending aorta and the aortic arch with reimplantation of the brachiocephalic trunk (BcTr) allowed the symptoms to resolve.

Predictors of Relapses or Recurrences in Patients With Giant Cell Arteritis: A Medical Records Review Study

OBJECTIVE

Giant cell arteritis (GCA) is the most common systemic vasculitis in individuals aged ≥50 years. Its course is marked by a high relapse rate requiring long-term glucocorticoid use with its inherent adverse effects. We aimed to identify factors associated with relapses or recurrences in GCA at diagnosis.

METHODS

We reviewed the medical records of consecutive patients with GCA diagnosed between 2009 and 2019 and followed for at least 12 months. We recorded their characteristics at onset and during follow-up. Factors associated with relapses or recurrences were identified using multivariable analysis.

RESULTS

We included 153 patients, among whom 68% were female with a median age of 73 (47-98) years and a median follow-up of 32 (12-142) months. Seventy-four patients (48.4%) had at least 1 relapse or recurrence. Headache and polymyalgia rheumatica were the most frequent manifestations of relapses. The first relapse occurred at a median time of 13 months after the diagnosis, with a median dose of 5.5 (0-25) mg/d of glucocorticoids.In multivariable analysis, patients with relapses or recurrences had a higher frequency of cough and scalp tenderness at diagnosis (20.3% vs 5.1%; odds ratio [OR], 4.73; 95% confidence interval [CI], 1.25-17.94; p = 0.022; and 41.9% vs 29.1%; OR, 2.4; 95% CI, 1.07-5.39; p = 0.034, respectively). Patients with diabetes mellitus at diagnosis had fewer relapses or recurrences during follow-up (5.4% vs 19%; OR, 0.24; 95% CI, 0.07-0.83; p = 0.024).

CONCLUSIONS

Cough and scalp tenderness at diagnosis were associated with relapses or recurrences, whereas patients with diabetes experienced fewer relapses or recurrences.

Pericardial effusion in giant cell arteritis is associated with increased inflammatory markers: a retrospective cohort study

OBJECTIVE

Giant cell arteritis (GCA) is the most frequent vasculitis affecting adults aged > 50 years. Cardiac involvement in GCA is considered rare, and only a few cases of pericarditis have been reported. The aim of this study was to determine the characteristics and prognosis of GCA patients suffering from pericardial involvement at diagnosis.

METHODS

We conducted a single-centre, retrospective chart review of patients with GCA in internal medicine departments (from 2000 to 2020). Patients were identified through a centralized hospital database. We retrospectively collected demographic, clinicobiological, histological, imaging, treatment and outcome data. Patients with pericardial effusion, defined as an effusion visible on the CT-scan performed at GCA diagnosis were compared to those without pericardial involvement.

RESULTS

Among the 250 patients with GCA, 23 patients (9.2%) had pericardial effusion on CT-scan. The comparison between the groups revealed similar distribution of age, gender, cranial symptoms and ocular ischaemic complications. Patients with pericardial effusion had a higher frequency of weight loss. They also had lower haemoglobin levels and higher platelet levels (p = 0.006 and p = 0.002, respectively), and they more frequently had positive temporal artery biopsy. There were no differences concerning the treatment, relapses, follow-up duration or deaths.

CONCLUSIONS

This case series sheds light on GCA as a cause of unexplained pericardial effusion or symptomatic pericarditis among adults aged > 50 years and elevated inflammatory biological markers. Fortunately, pericardial involvement is a benign GCA manifestation. In that context, the search for constitutional symptoms, cranial symptoms and associated signs of polymyalgia rheumatica is crucial for rapidly guiding GCA diagnosis.

Osteitis in Systemic Sclerosis: a nationwide case-control retrospective study (SCLEROS Study)

OBJECTIVE

Systemic sclerosis (SSc) is an autoimmune (AI) connective tissue disorder characterized by skin fibrosis, vasculopathy and dysimmunity. Data regarding osteitis in SSc are scarce.

METHOD

We performed a nationwide multicentre retrospective case-control study including patients with SSc according to the 2013 ACR/EULAR classification, with a diagnosis of osteitis. The objectives of the study were to describe, to characterize, and to identify associated factors for osteitis in patients with SSc.

RESULTS

Forty-eight patients were included. Twenty-six patients (54.1%) had osteitis beneath digital tip ulcers. Physical symptoms included: pain (36/48, 75%), erythema (35/48, 73%), and local warmth (35/48, 73%). Thirty-one (65%) patients had C-reactive protein levels >2 mg/L (8 [2.7 - 44.3] mg/L). On X-ray, CT-scans or MRI, osteitis was characterized by swelling or abscess of soft tissues with acro-osteolysis or lysis in 28 patients (58%). Microbiological sampling was performed in 45 (94%) patients. Most pathogens were Staphylococcus aureus (43.8%); anaerobes and Enterobacteriaceae (29.1%) and Pseudomonas aeruginosa (10.4%). Management comprised antibiotics in 37 (77.1%) patients and/or surgery in 26 (54.2%). Fluoroquinolones were used in 22 (45.8%) patients and amoxicillin + beta-lactamase inhibitor in 7 (14.6%). Six (12.6%) patients relapsed, 6 (12.6%) patients had osteitis recurrence, 15 (32%) sequelae, and 2 patients had septic shock and died.

CONCLUSION

This study confirmed digital tip ulcers as an associated factor for osteitis, and revealed a high rate of functional sequelae. Antimicrobial therapy with oral fluoroquinolone or intravenous amoxicillin and beta-lactamase inhibitor are used as first-line antibiotherapy in SSc patients with osteitis.

Characteristics of patients with systemic sclerosis suffering from a lower limb amputation: Results of a French collaborative study

Objective

Systemic sclerosis mainly affects the microvascular network. However, macrovascular manifestations have been reported. We aimed to investigate the characteristics of systemic sclerosis patients with an amputation of a lower limb segment.

Methods

We designed a retrospective, case-control, multicentric study on systemic sclerosis patients with amputation of a lower limb segment secondary to critical ischemia via the French Research Group on Systemic Sclerosis. For each case, a control (systemic sclerosis patient without lower limb symptom) was matched with sex, age (±5 years), and cutaneous subset of systemic sclerosis.

Results

In total, 26 systemic sclerosis patients (mean age of 67.2 ± 10.9 years, 20 females, 21 limited cutaneous forms) with a lower limb amputation and 26 matched controls (mean age of 67.3 ± 11.2 years, 20 females, 22 limited cutaneous forms) were included. At the time of amputation, the mean disease duration was 12.8 (±8.6) years. In comparison to controls, systemic sclerosis patients with amputation had more digital ulcers (p = 0.048), history of digital ulcers (p = 0.026), and a higher prevalence of pulmonary arterial hypertension (p = 0.024). Systemic sclerosis patients with amputation were more often smokers (p = 0.008) and under corticosteroids (p = 0.015). In the multivariate model, pulmonary arterial hypertension, smoking status, and corticosteroids were independent markers associated with lower limb amputation in systemic sclerosis. In the follow-up, 10 patients (38.5%) had recurrent ischemia requiring a new limb amputation, and five patients (19.2%) had an amputation of the contralateral limb.

Conclusion

This study identifies some markers associated with lower limb amputation in systemic sclerosis such as digital ulcers and pulmonary arterial hypertension and points out the high risk associated with tobacco consumption and corticosteroid use.

Use of Direct Oral Anticoagulants in Patients with Sickle Cell Disease and Venous Thromboembolism: A Prospective Cohort Study of 12 Patients

Patients with sickle cell disease have an increased risk of venous thromboembolism (VTE) and with a mortality 2-fold higher. The anticoagulation of VTE in a young population is an important question. Indeed, hemorrhagic complications of anticoagulation may occur more frequently than in the general population. The use of a direct oral anticoagulant (DOAC) is not recommended for VTE in patients with sickle cell disease because those patients were not included in the clinical studies. We aimed to study the safety of using DOACs in a prospective cohort of patients with sickle cell disease and VTE. We prospectively followed the cohort of all sickle cell disease patients undergoing recent DOAC treatment for VTE at a sickle cell disease reference center. Twelve patients received rivaroxaban for VTE (eight women and four men). The median age was 27 years (20-45). The sickle cell disease variants included homozygous Hb SS (HBB: c.20A>T) in eight patients, Hb S-β⁺-thalassemia (Hb S-β⁺-thal) in two, Hb S-β⁰-thal in one and Hb S-Hb C (HBB: c.19G>A) in one. The cumulative duration of follow-up was 3134 days under rivaroxaban treatment. There were two thrombotic events, including a patient with a double positivity of antiphospholipid antibodies. No major bleeding was observed, and 6/12 patients presented minor bleeding (epistaxis: n = 4; anal fissure bleeding: n = 1; menorrhagia n = 4). Of these, 3/6 required their treatment to be switched to apixaban, which stopped the bleeding. Direct oral anticoagulants may be an alternative treatment for VTE in patients with sickle cell disease, except for an associated antiphospholipid syndrome.

[Ocular syphilis, a re-emergent pathology: Series of 12 patients in one Hospital, 2017]

INTRODUCTION

Syphilis is a sexually transmitted disease. All organs might be affected, but ocular syphilis only occurs in 0.6 percent of patients. We collected all cases of ocular syphilis requiring hospitalization at the University Hospital Center (UHC) in Marseille in 2017.

PATIENTS AND METHODS

This was a retrospective monocentric study. The diagnosis of ocular syphilis was based on the combination of ocular inflammation with a positive syphilitic serology. For each patient, sex, age, HIV status, ocular and extraocular symptoms, initial visual acuity, syphilis serology, cerebrospinal fluid (CSF) analysis if done, treatment and clinical response were collected.

RESULTS

Ten men and two women, aged 28 to 86 years, were hospitalized. Two patients were HIV-positive. Ophtalmological lesions were heterogeneous the posterior structures were most affected. Anterior uveitis was isolated in one patient. Five patients had extraocular signs with cutaneous and/or mucosal involvement. No patient had neurological symptoms. Diagnosis of neurosyphilis through CSF analysis was definite for one patient, probable for 5 patients and ruled out for 2 patients. Six patients received treatment with penicillin G and six with ceftriaxone. Visual acuity improved in all cases.

DISCUSSION

Ophtalmic cases of syphilis have become more frequent over the past few years in France. The diagnosis should be suspected in cases of eye inflammation even in the absence of favourable clinical presentation or anamnesis. Search for HIV co-infection should be systematic. Our study shows that ceftriaxone remains an effective alternative to penicillin G.

[Eosinophilia heralding the diagnosis of eosinophilic fasciitis (Shulman's disease)]

INTRODUCTION

Eosinophilic fasciitis or Shulman's disease is characterized, in its typical form, by palpable thickening of the skin and soft tissues, blood hypereosinophilia and fascia lesions. We hereby report a case of eosinophilic fasciitis in which hypereosinophilia preceded for several months the clinical signs of fasciitis.

CASE REPORT

A 64-year-old woman, with a history of Little's syndrome with motor disability, was admitted in internal medicine for eosinophilia. For almost three months, no origin to the eosinophilia was found. The secondary onset of an edema and pain located on four limbs led to the diagnosis of eosinophilic fasciitis. Muscle magnetic resonance imaging was supportive and the muscle histological analysis confirmed the diagnosis of eosinophilic fasciitis. Treatment with steroids induced a rapid normalization of the eosinophilia and edema.

CONCLUSION

In this case report, eosinophilia was preceding the clinical cutaneous signs that led to the diagnosis of eosinophilic fasciitis. It is likely to believe that myalgias, frequently found in the onset of eosinophilic fasciitis, may have been hidden by the history of infantile encephalopathy. The diagnosis of eosinophilic fasciitis must be kept in mind of physicians in the investigation of an eosinophilia, even though cutaneous signs are lacking.
