Tocilizumab-induced psoriatic eruption : a case report and a case-based review.

BACKGROUND: Cases of psoriasis associated with Tocilizumab (TCZ) are scarce. OBJECTIVE: To describe a new case of TCZ-associated psoriasis and to perform a case-based review of similar cases. METHODS: We searched Medline/Pubmed, Embase, Scopus, Web of Science, and Directory of Open Access Journals databases using the terms « Tocilizumab ¼ and « Psoriasis ¼ in the French and English literature. RESULTS: We report a 70-year-old woman with a history of Rheumatoid Arthritis who developed Infliximab-induced plaque psoriatic eruption of the soles and palms, that resolved after Infliximab interruption, then relapsed after TCZ relay, and eventually resolved after TCZ interruption. Including our case, we identified 16 cases of TCZ-induced psoriatic eruption. Three (21%) out of 14 patients had a history of cutaneous psoriasis - data were not available for 2 patients. Eight (50%) patients had previously received TNFα antagonists. TCZ was stopped for 10 patients and continued for 4 patients. For the 2 remaining patients, the interval between two injections of TCZ was shortened. All the patients with available follow-up data had an improvement of the eruption within 4 weeks. CONCLUSION: To conclude, in case of TCZ-induced psoriatic eruption and in light of the published cases, we suggest using topical steroids and reassessing the patient 4 weeks later. If no healing is obtained, we suggest stopping TCZ, and treating the underlying disease with another drug. When no other drug is available, while waiting for more data regarding the value of IL-6 levels, it can be discussed to increase TCZ regimen, as it has been successful for 2 authors. Efficacy assessment of the chosen attitude should not take place before 4 weeks.

IgE monoclonal gammopathy: A case report and literature review.

Immunoglobulin E (IgE) gammopathy is a rare disorder, accounting for just 0.1% of all patients with multiple myeloma (MM). Herein, we report a case of IgE monoclonal gammopathy without any biological and clinical symptoms, and we review 63 published cases in the literature. Demographic, biological and clinical presentations and features appear to be similar to those of other subtypes of MM, with a median age of diagnosis of 67years. There is a slight excess of male patients, and incidence seems to increase with age. The prevalence of renal failure, anaemia and hypercalcaemia at diagnosis was computed to be at 26%, 44% and 18%, respectively, in patients with MM. According to the literature, IgE MM is more aggressive and associated with poorer survival. Nonetheless, cases that are prolonged have also been described.

[Ebola virus disease: Clinical presentation, prognosis and treatment]. / Maladie à virus Ebola : présentation clinique, aspects pronostiques et principes thérapeutiques.

The clinical spectrum of Ebola virus disease (EVD) ranges from very serious forms with organ failure and death within days to paucisymptomatic forms and perhaps even asymptomatic. The authors propose a focus on the clinical manifestations of EVD, on prognosis and on therapeutic aspects (excluding resuscitation). This work extracts from the literature the main data gathered during the 2014-2015 epidemic that raged in Guinea Conakry and Sierra Leone. These two countries, even if they are separated by a border, are one and the same population base. The characteristics of the epidemic in Liberia have not been analyzed. The authors have treated EVD patients in the health workers treatment center of Conakry and enrich this work about their personal experience.

[Global management of patients with ebola viral disease, experience of the Healthcare workers Treatment of Conakry, Guinea]. / Prise en charge globale du patient contaminé par le virus Ebola, expérience du Centre de traitement des soignants de Conakry, Guinée.

The Healthcare Workers Treatment Center of Conakry, Guinea, was inaugurated in january 2015. It is dedicated to the diagnosis and the treatment of healthcare workers with probable or confirmed Ebola viral disease. It is staffed by the french army medical service. The french military team may reconcile their medical practice and the ethno-cultural imperatives to optimise the patient adherence during his hospitalization.

[Imported hepatic amebiasis in adults: retrospective study of 58 cases]. / Amœbose hépatique importée de l'adulte : étude rétrospective de cinquante-huit observations.

The authors report the results of a retrospective study of patients hospitalized for serologically- confirmed hepatic amebiasis confirmed by serology in four French military hospitals from January 1, 2002, through December 31, 2012. The study included 58 patients (53 men, 5 women) with a median age of 41 years (range: 25-80). Among them, 34 (59%) were in the military, 10 (17%) were tourists, 10 migrants (15%), and 4 expatriates (5%). For 75%, contamination occurred in sub-Saharan Africa. The qualitative latex test was simple to use and reliable, even in the emergency department. Medical treatment by metronidazole alone was efficacious in 75% of the patients. Indications for drainage must be discussed according to the clinical and laboratory evidence.

[Fever as the presenting manifestation of colon cancer: a case series of 11 patients]. / Fièvre révélatrice d'un cancer colique: 11 observations.

INTRODUCTION: Fever happens frequently in colon cancer but it is rarely the presenting manifestation. PATIENTS AND METHODS: We report a case series of patients with colon cancer revealed by fever in the three military hospitals in Paris. RESULTS: Of the 11 patients studied, seven were men and four were women, and their mean age was 70 years. Cancer was localized in the sigmoid colon (n=6), left colon (n=3) and right colon (n=2). Cancer staging (UICC TNM classification 2002) was respectively pTis (n=1), I (n=4), II (n=3) and III (n=3). Fever was the only reason for admission and two patients had a recurrent fever of unknown origin. All patients but one had bacterial infection. Blood cultures grew up in six cases, Escherichia coli (n=3), Streptococcus gallolyticus (ex bovis) (n=2) and anaerobic bacteria (n=1). There was one case of infective endocarditis caused by S. gallolyticus. Imaging showed a liver abscess (n=3) and a colon cancer complicated by an abscess (n=3). In seven patients, a familial history of colon cancer and symptoms of underlying colic disease were present (neglected rectal bleeding, iron deficiency anaemia, clinical evidence of an abdominal mass). CONCLUSIONS: Fever may reveal colon cancer at an early stage. Its main cause is a bacterial infection, such as bacteremia or abscess. Fever of unknown origin is a rare presentation. Detailed history, careful clinical examination and analysis of imaging contribute to recommend the prescription of colonoscopy.

[Vascular manifestations due to Campylobacter fetus subsp. fetus infection: report of two cases]. / Manifestations vasculaires des infections à Campylobacter fetus subsp. fetus : à propos de deux cas.

INTRODUCTION: Campylobacter fetus is a rare Gram-negative bacteria affecting especially elderly and immunocompromised patients, and that is responsible of vascular and cutaneous involvement. OBSERVATIONS: We report two cases of C. fetus infection in two diabetic male patients, aged 75 and 85 years. The first patient was admitted for chronic fever. First-line examinations were inconclusive. Combined positron emission tomography and computed imaging tomography (PET-CT) diagnosed an infection of a previously operated popliteal aneurysm. The patient underwent surgery, and per-operative samples were positive for C. fetus. The second patient was admitted for a leg cellulitis. Blood cultures were positive for C. fetus. PET-CT found a septic superficial thrombophlebitis. The outcome was favorable for both patients with prolonged antibiotic therapy. CONCLUSION: Vascular involvement should be suspected in the presence of C. fetus infections. PET-CT may be useful, as other imaging modalities are not always contributive.

[Tropical sprue in an expatriate]. / Sprue tropicale chez un expatrié.

INTRODUCTION: Tropical sprue is a postinfective malabsorption syndrome that occurs in some tropical endemic areas. CASE REPORT: A 65-year-old Caucasian patient, with no significant past medical history, living in Cambodia for 10 years, presented with a 23 kg weight loss and chronic diarrhea. Clinical examination was unremarkable. Laboratory tests showed a moderate nutritional deficiency syndrome. The upper gastrointestinal endoscopy showed duodenal villous atrophy and histological analysis confirmed subtotal villous atrophy with important intraepithelial lymphocytosis. The diagnosis of tropical sprue was considered on the epidemiological, clinical and biological context, and the absence of other cause of villous atrophy. A three-month duration treatment with antibiotics, folic acid and vitamin B12 was initiated. The clinical course was favorable with disappearance of diarrhea in 15 days. One year later, the patient had resumed his usual weight, and laboratory tests and duodenal biopsies were normal. CONCLUSION: The diagnosis of tropical sprue should be systematically discussed in any malabsorption syndrome with villous atrophy in a patient living or having lived in the tropics.

[Mycoplasma pneumoniae: a cause of febrile hemolytic anemia in travelers]. / Mycoplasma pneumoniae: une cause d'hémolyse fébrile chez le voyageur.

Mycoplasma pneumoniae can cause varied hematologic manifestations that are frequently associated with lower respiratory tract infections. Acute febrile hemolysis without respiratory symptoms is quite rare. We describe the case of a 25-year-old man, admitted for acute fever with hemolysis, after returning from Djibouti. M. pneumoniae infection was proved by serological testing. A favorable outcome followed macrolide treatment.

[Use of positron emission tomography in sarcoidosis]. / Apport de la tomographie par émission de positons dans la prise en charge de la sarcoïdose.

FDG-PET, now hybrid positron emission tomography/computed tomography (PET-CT), has become an established diagnostic tool in oncology. Fluorodesoxyglucose ((18)F-FDG) is not specific for malignant lesions, as uptake of the tracer depends on its accumulation in cells with an increased glucose metabolism as it is also the case in infectious and inflammatory lesions, like sarcoidosis. Thus, FDG-PET has been proposed for internal medicine indications, one of whom is sarcoidosis. The main characteristics of FDG-PET are its better sensitivity compared to (67)Ga scintigraphy and its ability to be used as an earlier marker of therapeutic response as compared with anatomy-based and conventional scintigraphic imaging. However, FDG-PET should be used in atypical or advanced stage of the disease. Future prospective studies should be awaited before integrating FDG-PET in clinical routine for treatment outcome and disease activity assessment in sarcoidosis. New radiopharmaceutical probes are under development and will improve the performance of PET.

[Pleuropulmonary manifestations of necrotising vasculitis]. / Manifestations pleuropulmonaires des vascularites nécrosantes.

The pleuropulmonary manifestations of necrotising vasculitis are frequent and polymorphic. If the existence of extrapulmonary signs and the presence of neutrophil polynuclear anticytoplasmic antibodies are helpful for the diagnosis of a bout of vasculitis, the existence of pleuropulmonary symptoms can also make for discussion of infections or iatrogenic effects induced by immunosuppressive treatments.

[Prolonged fever: specific issues in the young adult population]. / Les fièvres prolongées: problématique chez l'adulte jeune.

Early studies on prolonged fever date back to the 1960s. Fifty years later, prolonged unexplained fever remains a diagnostic challenge to the general internists. Although the aetiologies of prolonged fevers have not changed much in the general population, the distribution between the various causes is not the same anymore. A regular decrease in infectious and neoplastic causes is noticed whatever the age. Prolonged fevers related to inflammatory disorders and fevers that remain of unknown origin still represent approximately 30 to 50% of the cases. In the young adult population, as in the older patients, prolonged fevers can be attributed to four groups: infection, inflammation, neoplasic and other aetiologies (including drug-related fevers). In the young adult population, the management of prolonged fever presents some specific issues that are the purpose of this review coupled with our own experience. The prognosis of undiagnosed prolonged fever is usually favourable, as a life-threatening aetiology is exceptionally diagnosed during the follow-up if the initial management was complete and accurate.

[Usefulness of JAK2 mutation assessment in recurrent deep venous thrombosis]. / La recherche de la mutation JAK2 peut-elle être utile dans le bilan étiologique d'une maladie thromboembolique récidivante ?

The search of JAK2 V617F mutation is a useful tool for the diagnosis of myeloproliferative disorders (MPD). This case report highlights the potential usefulness of this testing in recurrent deep venous thrombosis (DVT) of lower limb. We report a 73-year-old man who presented with three spontaneous episodes of lower limb DVT. The third episode occured while he was receiving fluindione. MPD was suspected because of an increased hematocrit (55 %) and hemoglobin (17g/dl) level. Red cell blood volume was increased and a JAK2 V617F mutation was detected confirming the diagnosis of polycythemia vera. The usefulness of JAK2 mutation for the diagnosis of MPD has been widely demonstrated. Also, some studies confirmed its usefulness in apparently idiopathic abdominal venous thrombosis. This report highlights the possible interest of JAK2 mutation in unexplained recurrent lower limb DVT, especially when it occurs under anticoagulant therapy.

[Ofloxacin is contraindicated in case of G6PD deficiency: is it evidenced based?]. / L'ofloxacine est contre-indiquée en cas de déficit en glucose 6 phosphate déshydrogénase (G6PD) : une évidence médicale basée sur les preuves ?

G6PD deficiency is very frequent with almost 400 millions of patients worldwide in Asia, Africa and Mediterranean. G6PD deficiency is involved in mild or severe haemolysis and the precipitating factor is usually a drug. More than 100 drugs have been implicated and fluoroquinolones are one of the more classic. However, the literature review shows that only a few observations have been clearly documented.

[Microscopic colitis associated with celiac disease probably triggered by the administration of venlafaxine]. / Association d'une colite lymphocytaire à une maladie coeliaque probablement déclenchée par la prise de venlafaxine (Effexor).

The association of microscopic colitis with celiac disease is rare. A case of microscopic colitis associated with celiac disease and following administration of venlafaxine in a 67-year-old patient is described. The pathophysiologic hypotheses of such an association are discussed.

[Acute renal insufficiency after flurbiprofen treatment in a patient treated with angiotensin converting enzyme inhibitor]. / Insuffisance rénale aiguë après prise de flurbiprofène chez un patient sous inhibiteur de l'enzyme de conversion.

We report a case of acute renal insufficiency in a 77 year-old patient who took flurbiprofen as antiplatelet therapy. This is an important observation because it illustrates the potential risk of acute renal insufficiency, when using flurbiprofen before invasive medical examination or surgery in patients receiving long-term treatment with angiotensin converting enzyme inhibitors or angiotensin II inhibitors. This risk is probably underestimated in usual clinical practice.

[Diagnosis of anemia in alcoholic cirrhosis]. / Diagnostic des anémies au cours des cirrhoses alcooliques.

PURPOSE: Anemia in patients with alcoholic liver cirrhosis is a common issue. The diagnosis could be difficult because of the multiplicity of causes, usually associated, and specificities in the diagnostic approach. This subject has not been reviewed for almost two decades. We propose a review based upon analysis of the literature and our clinical experience. CURRENT KNOWLEDGE AND KEY POINTS: Because of the alcoholism and the biological consequences of the liver disease, laboratory findings, especially the mean corpuscular volume, should be interpreted with caution in the diagnostic approach. Despite these drawbacks, the diagnosis of anemia is detailed according to the usual plan: normocytic, macrocytic and microcytic anemias. Finally, we propose practical guidelines. FUTURE PROSPECTS AND PROJECTS: Further prospective studies should assess the real burden of nutritional deficiencies, easily treatable. The prognostic significance of hemolytic anemias in patients with alcoholic liver cirrhosis should be studied.
