Infective endocarditis in pregnant women without intravenous drug use: a multicentre retrospective case series.

OBJECTIVES: To describe the clinical features and outcomes of infective endocarditis (IE) in pregnant women who do not inject drugs. METHODS: A multinational retrospective study was performed at 14 hospitals. All definite IE episodes between January 2000 and April 2021 were included. The main outcomes were maternal mortality and pregnancy-related complications. RESULTS: Twenty-five episodes of IE were included. Median age at IE diagnosis was 33.2 years (IQR 28.3-36.6) and median gestational age was 30 weeks (IQR 16-32). Thirteen (52%) patients had no previously known heart disease. Sixteen (64%) were native IE, 7 (28%) prosthetic and 2 (8%) cardiac implantable electronic device IE. The most common aetiologies were streptococci (n = 10, 40%), staphylococci (n = 5, 20%), HACEK group (n = 3, 12%) and Enterococcus faecalis (n = 3, 12%). Twenty (80%) patients presented at least one IE complication; the most common were heart failure (n = 13, 52%) and symptomatic embolism other than stroke (n = 4, 16%). Twenty-one (84%) patients had surgery indication and surgery was performed when indicated in 19 (90%). There was one maternal death and 16 (64%) patients presented pregnancy-related complications (11 patients ≥1 complication): 3 pregnancy losses, 9 urgent Caesarean sections, 2 emergency Caesarean sections, 1 fetal death, and 11 preterm births. Two patients presented a relapse during a median follow-up of 3.1 years (IQR 0.6-7.4). CONCLUSIONS: Strict medical surveillance of pregnant women with IE is required and must involve a multidisciplinary team including obstetricians and neonatologists. Furthermore, the potential risk of IE during pregnancy should never be underestimated in women with previously known underlying heart disease.

Imaging of Human Neurolisteriosis: A Prospective Study of 71 Cases.

Background: Neurolisteriosis ranks among the most severe neurological infections. Its radiological features have not been thoroughly studied. We describe here the neuroradiological features of neurolisteriosis and assess their prognostic value. Methods: Patients with microbiologically proven neurolisteriosis were enrolled from November 2009 to October 2013 in MONALISA study. Magnetic resonance and computed tomography images were studied by 2 independent neuroradiologists. Predictors of 3-month mortality were determined using logistic regression. Results: Seventy-one patients were included; 42 were men (59%). Mean age was 64 years. Sixty patients (85%) reported signs of encephalitis, with clinical brainstem involvement in 16 (23%). Images were abnormal in 87% of cases (62/71). Main neuroradiological images were meningeal enhancement (25/71, 35%), abscess(es), or nodular image(s) evocative of abscess (10/71, 14%), hemorrhages (11/71, 15%), contrast-enhancing ventricles, or hydrocephalus (7/71, 10%). White-matter images (42/71, 59%), dilated Virchow-Robin spaces (22/71, 31%), and cerebral atrophy were also reported (34/71, 48%). Brainstem involvement (meningeal enhancement, abscess) was reported in only 7/71 cases (10%). Three-month survival was lower in patients with hydrocephalus or contrast-enhancing ventricles (1/7 [14%] than without [47/64, 73%], P = .005) and in patients with parenchymal images (abscess[es], nodule[s]\, or white matter images; 25/46 [54%] vs 23/25 without [92%], P = .004). Parenchymal images were associated with lower 3-month survival in the multivariable model (odds ratio 5.60, 95% confidence interval [1.42-29.6], P = .02). Conclusions: Neurolisteriosis presents as a combination of neuroradiological images, none being specific. Radiological signs of rhombencephalitis are uncommon, whereas, unexpectedly, hemorrhagic images are frequent. The negative prognostic value of parenchymal neuroradiological images was evidenced. Clinical Trials Registration: NCT01520597.

Candida vertebral osteomyelitis (CVO) 28 cases from a 10-year retrospective study in France.

Although increasingly frequent, little is known about the clinical presentation, radiological signs, and outcome of Candida vertebral osteomyelitis (CVO).We performed a nationwide retrospective study of laboratory-confirmed cases of CVO over a 10 year-period in France with a prolonged follow-up. We describe demographic, clinical, biological, and radiological characteristics of patients with CVO, patients' management, and long-term outcome and determine factors associated with a poor outcome.In total, 28 patients with laboratory-confirmed CVO were included. A prior systemic Candida infection was evidenced in 13/28 (46%), occurring a median of 6 weeks before CVO was diagnosed. Twenty-six of 28 (93%) had at least 1 underlying condition at risk of invasive fungal disease, and in 19/28 (68%) CVO was health-care related. C albicans was most frequently identified (21/28; 75%) Lumbo-sacral involvement was the most prevalent (20/28-71%). Nearly half patients had no fever at presentation, but all had pain. Initial antifungal therapy consisted in fluconazole in 15/28 (53%); surgery was needed in 5 (18%) cases.One-year mortality was 21% (6/28), directly related to fungal infection in 2 patients. Risk-factors associated with 1-year mortality were age (P=.02), a high Charlson comorbidity index (P = .001), and a shorter treatment duration (median, 3 months vs 6 months; P = .02). Among 22 patients who survived, the median follow up duration was 15.5 months (8-93.5); 10 had sequelae, consisting in pain in all and neurological deficit in one. A longer treatment duration was significantly associated with healing without sequelae (P = .04).CVO concerns patients with serious underlying conditions and risk-factors for invasive candidiasis. Prolonged antifungal treatment appears to improve survival without sequelae.

Imported African histoplasmosis in an immunocompetent patient 40 years after staying in a disease-endemic area.

Histoplasmosis caused by Histoplasma capsulatum var. duboisii is a rare disease outside central and western Africa. In Europe, all cases are imported. We report a case of an African histoplasmosis with isolated pulmonary involvement in a non-immunocompromised patient that occurred 40 years after his stay in a disease-endemic area. The patient was given itraconazole. (18)F-fluoro-2-deoxy-d-glucose positron emission tomography-computed tomography was used to assess evolution during treatment. The outcome for the patient was favorable.
