Acute onset myopericarditis as unusual presentation of primary HIV infection

A 30-year-old man was admitted to hospital after complaining of a retrosternal burning pain, radiating to the jugular region, and to both upper limbs. An electrocardiography examination showed a ST segment elevation involving the lower-lateral leads. A trans-thoracic ultrasonography showed findings compatible with an acute myopericarditis. All performed serological testings excluded other recent infections with cardiac tropism. Among screening tests, a peripheral lymphocyte subset analysis was performed and an inversion of the CD4/CD8 ratio was found. Therefore, HIV testing was performed and proved positive for HIV-1 antibodies. The discovery of a primary HIV infection with involvement of a vital organ led us to start HAART. On day 20, our patient underwent a right heart catheterization and endomyocardial biopsy. During the following days, the clinical conditions of our patient improved, and a further heart ultrasonography documented a mild pericardial thickening as a result of the recent myopericarditis. Also the evolving changes of ECG were compatible with a benign evolution of myopericarditis. The histopathologic studies revealed a mild fibrosis of the myocardial right ventricular tissue, and inflammatory findings compatible with a recent myocarditis. At the real-time PCR analysis on bioptic sample, only HHV6 DNA and HIV-DNA were reactive. An immunofluorescence staining was performed to highlight the HIV p24 protein and a positive signal was detected in myocardial tissue. Considering the low avidity level of the anti-HIV IgG antibodies and the positivity of HIV-DNA in the endomyocardial tissue, we believe that the clinical manifestation presented can be referred to the recent primary HIV-infection

Potential role of T2Candida in the management of empirical antifungal treatment in patients at high risk of candidaemia: a pilot single-centre study

Objectives: We estimated the diagnostic accuracy of T2Candida, with blood culture (BC) as the gold standard, and compared turnaround time between these two techniques in order to investigate the potential role of T2Candida in the management of empirical antifungal treatment (EAT). Methods: We performed a single-centre prospective observational study in patients with severe sepsis or septic shock and multiple risk factors for candidaemia. Results: We analysed 46 out of 50 screened patients. All patients received an echinocandin as EAT; the median EAT duration was 7 days (IQR 4\u201313 days). BCs were negative in 31 (67.4%) patients, positive for bacteria in 14 (30.4%) patients and positive for Candida albicans in 1 (2.2%) patient. T2Candida was negative, invalid and positive in 37, 5 and 4 patients, respectively. T2Candida and BC results were concordant in all but three patients, where T2Candida was positive and BCs were negative. Two of them were on antifungal prophylaxis at the time of enrolment. T2Candida reduced time to a negative result by 5 days. T2Candida performance was: sensitivity "100% (95% CI 2.5%\u2013100%), specificity" 91.8% (95% CI 78%\u201398%), positive predictive value "25% (95% CI 0.63%\u201380.6%) and negative predictive value " 100% (95% CI 89.7%\u2013100%). Conclusions: In patients with multiple risk factors for candidaemia and severe sepsis or septic shock, T2Candida may be helpful to reduce the length of EAT

Exploring the emotional and behavioural profile in paediatric narcolepsy type 1: A case–control study

Narcolepsy type 1 (NT1) is a central disorder of hypersomnolence often arising in childhood and adolescence. NT1 has a significant, but poorly defined, psychological impact. We aimed to investigate the psycho-social functioning of children and adolescents with NT1. We performed a cross-sectional, child and parent-reported questionnaire survey in 37 children and adolescents (6-17 years) with NT1, compared with age- and sex-matched controls. Questionnaires (SSHS, ESS-CHAD, CDI, MASC, CBCL, CRS-R, and SNAP-IV) evaluated various aspects of behavioural and emotional profiles, sleep habits, and daytime sleepiness. Subsequently, NT1 intra-group analysis was performed to investigate the effect of sex (males vs females) and pharmacological treatment (treated vs non-treated) on psychological features. The NT1 questionnaires total scores were then correlated with the clinical characteristics (age, body mass index [BMI], ESS-CHAD score, cerebrospinal hypocretin-1 [Hcrt-1] levels, and diagnostic delay). Patients with NT1 showed a higher tendency to depressive symptoms, anxiety, somatisation, inattention, hyperactivity, oppositional/defiant problems, and other maladaptive behaviours compared with controls. Among NT1 patients, females showed a higher propensity to anxiety, and non-treated patients displayed higher depressive symptoms. Psychological symptoms increased with age, BMI, and daytime sleepiness in patients with NT1, while a younger age was associated with more frequent somatisation symptoms. Lower cerebrospinal Hcrt-1 levels correlated with poorer social competencies, daily activities, and inattention. Diagnostic delay was associated with a higher impact of depressive symptoms and behavioural problems. NT1 in children and adolescents is associated with poorer functioning in multiple psychological domains calling for a multidisciplinary approach and monitoring to reduce disease burden and to prevent psychiatric consequences
