Comparison of screening tools for the detection of neurocognitive impairment in HAART-treated patients

Background: Neurocognitive impairment (NCI) and HIV-associated neurocognitive disorders (HAND) remain prevalent despite HAART. We examined sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and correct classification rate (CCR) of screening tools for the detection of NCI and HAND in HAART treated patients. Methods: We examined 101 unselected HAART-treated patients. Patients were administered the self-reported three questions (EACS Guidelines), the International HIV-Dementia Scale (IHDS), the Mini-Mental Status Examination (MMSE), and a comprehensive 6-domain (17-test) neuropsychological (NP) battery (120 minutes) that included, among others, the Digit Symbol (DS), the Trail Making Modalities (TM), and the Grooved Pegboard (GP) tests. NCI was defined according to the AAN criteria. HAND was diagnosed after exclusion of confounding conditions. Results: Our cohort was relatively healthy (mean CD4 count: 575 cells/mm3, undetectable plasma HIV RNA 85%). Prevalence of NCI and HAND were 39.6% (40 of 101) and 30.7% (31 of 101), respectively. Mean scores of IHDS (9.9 vs 10.8; p<0.001) and MMSE (26.8 vs 28.2; p=0.004) differed significantly between impaired and unimpaired patients, while mean three-questions scores (8.0 vs 7.0; p=0.23) did not. The three questions showed also poor sensitivity for the detection of both NCI (20%) and HAND (22%). The IHDS showed fairly good sensitivity (55%) and NPV (73.5%). Adding to the IHDS some easy to administer NP tests, i.e. TM, DS, and GP, resulted in an increase in sensitivity and NPV for the detection of NCI (table). Similar results were obtained regarding the detection of HAND (not shown in table). Conclusions: Both NCI and HAND are still very prevalent in HAART-treated patients. Among screening tools the self-reported three question show poor sensitivity. The IHDS performed better in terms of sensitivity, PPV, and NPV. Combinations of easy-to-administer NP tests with the IHDS resulted in increased sensitivity and NPV. Combining IHDS with one or two simple NP test may represent an improvement in the screening approach to the detection of both NCI and HAND

Acute rhabdomyolysis and delayed pericardial effusion in an Italian patient with Ebola virus disease : a case report

Background: During the 2013-2016 West Africa Ebola virus disease (EVD) epidemic, some EVD patients, mostly health care workers, were evacuated to Europe and the USA. Case presentation: In May 2015, a 37-year old male nurse contracted Ebola virus disease in Sierra Leone. After Ebola virus detection in plasma, he was medically-evacuated to Italy. At admission, rhabdomyolysis was clinically and laboratory-diagnosed and was treated with aggressive hydration, oral favipiravir and intravenous investigational monoclonal antibodies against Ebola virus. The recovery clinical phase was complicated by a febrile thrombocytopenic syndrome with pericardial effusion treated with corticosteroids for 10days and indomethacin for 2months. No evidence of recurrence is reported. Conclusions: A febrile thrombocytopenic syndrome with pericardial effusion during the recovery phase of EVD appears to be uncommon. Clinical improvement with corticosteroid treatment suggests that an immune-mediated mechanism contributed to the pericardial effusion

Interaction Between Diabetes Mellitus and Platelet Reactivity in Determining Long-Term Outcomes Following Percutaneous Coronary Intervention

Diabetes mellitus (DM) is an independent predictor of adverse outcomes in patients with coronary artery disease (CAD). We investigated the interaction between DM and high platelet reactivity (HPR) in determining long-term clinical outcomes after percutaneous coronary intervention (PCI). We enrolled 500 patients who were divided based on the presence of DM and HPR. Primary endpoint was the occurrence of major adverse clinical events (MACE) at 5 years. Patients with both DM and HPR showed the highest estimates of MACE (37.9%, log-rank p < 0.001), all-cause death (15.5%, log-rank p = 0.022), and non-fatal myocardial infarction (25.9%, log-rank p < 0.001). At Cox proportional hazard analysis, the coexistence of DM and HPR was an independent predictor of MACE (HR 3.46, 95% CI 1.67-6.06, p < 0.001). Among patients with stable CAD undergoing elective PCI and treated with aspirin and clopidogrel, the combination of DM and HPR identifies a cohort of patients with the highest risk of MACE at 5 years

Impact of Chronic Kidney Disease and Platelet Reactivity on Clinical Outcomes Following Percutaneous Coronary Intervention

We investigated the interaction between chronic kidney disease (CKD) and high platelet reactivity (HPR) in determining long-term clinical outcomes following elective PCI for stable coronary artery disease (CAD). A total of 500 patients treated with aspirin and clopidogrel were divided based on the presence of CKD (defined as glomerular filtration rate of &lt; 60 ml/min/1.73 m2) and HPR (defined as a P2Y12 reaction unit value ≥ 240 at VerifyNow assay). Primary endpoint was the occurrence of major adverse clinical events (MACE) at 5 years. Patients with both CKD and HPR showed the highest estimates of MACE (25.6%, p = 0.005), all-cause death (17.9%, p = 0.004), and cardiac death (7.7%, p = 0.004). The combination of CKD and HPR was an independent predictor of MACE (HR 3.12, 95% CI 1.46–6.68, p = 0.003). In conclusion, the combination of CKD and HPR identifies a cohort of patients with the highest risk of MACE at 5 years
