Oxford-AstraZeneca COVID-19 vaccine: need of a reasoned and effective vaccine campaign.

OBJECTIVES: A strong COVID-19 vaccine campaign is needed to reach the herd immunity and reduce this pandemic infection. STUDY DESIGN: In the Foch Hospital, France, in February 2021, 451 healthcare workers were vaccinated by a first dose of AstraZeneca vaccine. METHODS: Adverse effects were reported to our pharmaco-vigilance circuit, by an online and anonymous questionnaire following the first weeks of the vaccinal campaign to healthcare workers. RESULTS: Two hundred seventy-four (60.8%) of them reported multiple adverse effects. Main adverse effects reported were feverish state/chills (65.7%), fatigue/physical discomfort (62.4%), arthralgia/muscle pain (61.0%) and fever (44.5%). CONCLUSIONS: On March 2021 many European countries suspended AstraZeneca vaccine for one week due to safety uncertainty. Thus, confidence in its efficacy is undermined. However, the benefit/risk balance is clearly in favor of vaccination.

Increase in sexually transmitted infections in a cohort of outpatient HIV-positive men who have sex with men in the Parisian region.

OBJECTIVE: To describe the increased incidence of sexually transmitted infections (STIs) in a cohort of HIV-infected men who have sex with men (MSM), followed in a tertiary hospital of the Île-de-France region. MATERIALS AND METHODS: We performed a monocentric, retrospective, and prospective study. We included symptomatic HIV-infected MSM patients who consulted for their annual consultation. RESULTS: One hundred and eighty patients were seen between 2008-2011 and 215 between 2012-2015. We observed an increased incidence of STIs between the two periods (14 and 29.3%, respectively). These STIs includes: syphilis, hepatitis C, urethritis, and proctitis due to Chlamydia trachomatis and Neisseria gonorrhea. CONCLUSION: A better management of symptomatic and asymptomatic STIs is needed for HIV-infected MSM patients.

Very prolonged liposomal amphotericin B use leading to a lysosomal storage disease.

Amphotericin B is a powerful polyene antifungal drug used for treating systemic fungal infections and is usually administered for a short period. Side effects after prolonged use are unknown in humans. Here we report the case of a 28-year-old man suffering from chronic granulomatous disease (CGD), treated for invasive cerebral aspergillosis with liposomal amphotericin B (L-AmB) for a very long time (8 consecutive years). We describe the efficacy and safety of this treatment in the long term. Aspergillosis was kept under control as long as L-AmB therapy was maintained, but relapsed when the dose was reduced. No overt renal toxicity was noted. The patient gradually developed hepatosplenomegaly and pancytopenia. Abnormalities of bone marrow were similar to the sea-blue histiocyte syndrome. Liver biopsy showed images of nodular regenerative hyperplasia related to CGD as well as a histiocytic storage disease. We discuss the very prolonged use of L-AmB leading to the development of a lysosomal storage disease.

[Cutaneous mucormycosis caused by Rhizopus microsporus]. / Mucormycose cutanée à Rhizopus microsporus.

BACKGROUND: Mucormycosis are rare fungal infections occurring chiefly in the lung or the rhinocerebral compartment, particularly in patients with immunodeficiency or mellitus diabetes. We report the case of an elderly patient with cutaneous mucormycosis caused by Rhizopus microsporus. PATIENTS AND METHODS: An 89-year-old man presented a skin lesion of the forearm rapidly becoming inflammatory and necrotic. The patient had been treated for 2months with oral corticosteroids for idiopathic thrombocytopenia. Histological and mycological examination of the skin biopsy revealed the presence of a filamentous fungus, R. microsporus. The outcome was unfavorable, despite prescription of high-dose liposomal amphotericin B. DISCUSSION: Mucormycosis are infrequent opportunistic infections caused by angio-invasive fungi belonging to the Mucorales order. Cutaneous presentations are rare, and in rare cases the species R. microsporus is isolated in clinical samples. Diagnosis is based on histological examination highlighting the characteristic mycelium within infected tissue, together with ex vivo mycological identification using morphological and molecular methods. Treatment consists of liposomal amphotericin B combined with debridement surgery. CONCLUSION: R. microsporus is a marginal fungal species rarely isolated in clinical practice, and even less in dermatology departments. This clinical case report highlights the severity of infection with this fungus, particularly in the absence of early surgery.

[Mastitis revealing Churg-Strauss syndrome]. / Mastite révélatrice d'un syndrome de Churg-Strauss.

BACKGROUND: Churg-Strauss syndrome often involves the skin, and this may sometimes reveal the disease. OBSERVATION: A 25-year-old woman was referred to a gynaecologist for inflammation of the right breast with breast discharge. Cytological analysis of the liquid showed numerous inflammatory cells, particularly polymorphonuclear eosinophils and neutrophils. Ultrasound examination of the breast was consistent with galactophoritis. CRP was normal, and hypereosinophilia was seen. The patient was subsequently referred to a dermatology unit. Skin examination revealed inflammation of the entire breast, which was painful, warm and erythematous; the border was oedematous with blisters. Necrotic lesions were also present on the thumbs and knees. Skin biopsy of the breast showed a dermal infiltrate with abundant infiltrate of polymorphonuclear eosinophils, including patchy necrosis and intraepidermal vesicles. Histological examination of a biopsy sample from a thumb revealed eosinophilic granuloma and leukocytoclastic vasculitis. The patient was also presenting asthma, pulmonary infiltrates and mononeuropathy at L3, consistent with Churg-Strauss syndrome. DISCUSSION: Breast involvement in Churg-Strauss syndrome is very rare (only one other case has been reported). This is the first case in which the breast condition revealed the disease. Cutaneous involvement of the breast is, however, also compatible with Wells' cellulitis. The lesions quickly disappeared with 1mg/kg/d oral prednisolone.

[Disseminated varicella-zoster virus infection with hemorrhagic gastritis during the course of chronic lymphocytic leukemia: case report and literature review]. / Infection disséminée au virus varicelle-zona avec gastrite hémorragique compliquant une leucémie lymphoïde chronique : une observation et revue de la littérature.

INTRODUCTION: The reactivation of varicella-zoster virus occurs in immunocompromised patients, especially in cases of hematological malignancy. Disseminated reactivation could involve digestive tract with life-threatening condition. CASE REPORT: A 76-year-old woman, with a history of chronic lymphocytic leukemia, presented with left hypochondrium pain, and a vesicular rash with hemorrhagic shock that revealed an hemorrhagic gastritis due to varicella-zoster virus. The literature review identified 28 additional cases of gastrointestinal mucosal damage during reactivation of varicella-zoster virus. Mortality is 40%. We report here the first case in the course of low-grade lymphoid malignancy. CONCLUSION: Acute gastrointestinal symptoms in immunocompromised patients should evoke a varicella-zoster virus reactivation with gastrointestinal involvement. This clinical manifestation, although rare, should not be ignored because of its severity.

Changes in the nail unit in patients with secondary lymphoedema identified using clinical, dermoscopic and ultrasound examination.

BACKGROUND: Secondary lymphoedema is characterized by lymphatic stasis that is often the result of a lymph node lesion. At advanced stages it may cause trophic changes in the skin. However, the presence of changes in the nail unit has not been reported to date. OBJECTIVES: The aim of this study was to determine the presence of nail abnormalities in cases of secondary lymphoedema. METHODS: This was a prospective study, conducted on patients with unilateral secondary lymphoedema. A comparative clinical and dermoscopic examination and 20-MHz high-resolution ultrasound imaging of the affected limb and the contralateral limb were performed. RESULTS: Thirty-three patients were included. On physical examination, hyperkeratosis of the lateral nail folds, friability of the nail surface, 'ragged' proximal nail folds and cuticle and apparent leuconychia were observed more frequently on the lymphoedematous limb. The ultrasound study of the nails of the thumb and the big toe did not reveal any differences in thickness of the different structures of the nail between the lymphoedema side and the opposite side. The nail matrix was longer on the lymphoedema side. CONCLUSIONS: Our study showed mild changes in the nail unit compatible with the xerosis often associated with severe lymphoedema. However, the study also showed frequent evidence of 'ragged' cuticles, which in these patients at high risk of erysipelas are entry points for bacteria. This should be taken into account when counselling patients with limb lymphoedema in order to prevent erysipelas.
