Disseminated toxoplasmosis in non-allografted patients with hematologic malignancies: report of two cases and literature review.

Toxoplasmosis can be a severe opportunistic infection in patients with acquired immunodeficiency syndrome (AIDS), and also among solid organ transplant and allogeneic hematopoietic stem cell transplant (HSCT) patients. Patients with low-grade or chronic hematologic malignancies are treated with increasing immunosuppressive regimens and, therefore, represent an emerging population at risk for opportunistic diseases. We report here two cases of disseminated toxoplasmosis occurring in non-allografted hematologic patients with chronic lymphoproliferations. A review of 44 cases from the literature reveals that toxoplasmosis occurs increasingly in indolent B cell lymphoproliferative disorders. Aggressive lymphoproliferations, adenosine analogs, autologous HSCT, and the absence of chemoprophylaxis are the main risk factors for opportunistic toxoplasmosis. The central nervous system is the main organ involved. Fever is only present in half of all cases. Latent Toxoplasma cysts reactivation (LTCR) is the most common, but primary infection occurs in about 20% of cases. Global mortality is over 50%.

The French Infectious Diseases Society's readiness and response to epidemic or biological risk-the current situation following the Middle East respiratory syndrome coronavirus and Ebola virus disease alerts.

CONTEXT: In 2012, the French Infectious Diseases Society (French acronym SPILF) initiated the "Coordination of epidemic and biological risk" (SPILF-COREB - Emergences [SCE]) group to support the readiness and response of healthcare workers (HCWs) to new alerts. OBJECTIVE: To present the SCE group, its functioning, and the main support it provided for frontline HCWs. METHODS: A multidisciplinary group of heads of infectious disease departments from reference hospitals was created to build a network of clinical expertise for care, training, and research in the field of epidemic and biological risk (EBR). The network developed a set of standardized operational procedures (SOPs) to guide interventions to manage EBR-suspect patients. RESULTS: A working group created the SOP aimed at frontline HCWs taking care of patients. Priority was given to the development of a generic procedure, which was then adapted according to the current alert. Five key steps were identified and hierarchized: detecting, protecting, caring for, alerting, and referring the EBR patient. The interaction between clinicians and those responsible for the protection of the community was crucial. The SOPs validated by the SPILF and its affiliates were disseminated to a wide range of key stakeholders through various media including workshops and the SPILF's website. CONCLUSION: SPILF can easily adapt and timely mobilize the EBR expertise in case of an alert. The present work suggests that sharing and discussing this experience, initiated at the European level, can generate a new collective expertise and needs to be further developed and strengthened.

Aspergillus spp. invasive external otitis: favourable outcome with a medical approach.

Aspergillus spp. invasive external otitis (IEO) is a rare infection. We performed a seven-year, single-centre retrospective study from 2007 to 2014 including all patients with proven Aspergillus spp. IEO. Twelve patients were identified. All patients had a poorly controlled diabetes mellitus and one underwent solid organ transplant. The most frequently isolated species was Aspergillus flavus (n = 10) and voriconazole was the first-line therapy in all cases, with a median length of treatment of 338.5 days (158-804 days). None of the patients underwent extensive surgery. The clinical outcome was excellent. However, otological sequelae were reported, including hearing impairment (n = 7) and facial palsy (n = 3).

[Post-splenectomy complications in primary immune thrombocytopenia. Literature review and preventive measures]. / Complications de la splénectomie au cours du purpura thrombopénique immunologique. Revue de la littérature et mesures de prévention.

Management of primary immune thrombocytopenia (ITP) has changed, and clinical practice broadens the use of thrombopoietin receptor agonists and anti-CD20 antibody as options for second-line therapy, as alternative to splenectomy. Splenectomy remains a successful, definitive curative treatment. The purpose of this review about the complications of the splenectomy, in the context of ITP, is to increase the awareness of clinicians towards the preventive measures, which are often not correctly applied.
