Association of hepatitis B virus infection with decreased ischemic stroke
ConclusionHBV was correlated with a reduced risk of AIS development. Although a decrease in AIS risk was noted in the patients with HBV, preventing the development of AIS in this population warrants further attention.

Stroke in HIV-infected African Americans: a retrospective cohort study
Abstract The risk of having a first stroke is nearly twice as high among African Americans compared to Caucasians. HIV/AIDS is an independent risk factor for stroke. Our study aimed to report the risk factors and short-term clinical outcomes of African Americans with HIV infection and new-onset stroke admitted at the Johns Hopkins Hospitals (2000–2012). Multivariate linear regression was used to examine the association between potential predictors and odds of an unfavorable outcome, defined as a higher modified Rankin Scale (mRS) score on hospital discharge. African Americans comprised 105/125 (84 %) of HIV-inf...

Clinical Reasoning: A 28-year-old man with progressive gait disturbance and encephalopathy
A 28-year-old man with sickle cell disease presented with 7 months of difficulty walking. Initial examination 3 months prior to admission to our hospital was thought to be consistent with a polyneuropathy. He was areflexic, was unable to stand on toes or heels with decreased sensation on the left foot to light touch and vibration, had difficulty with heel to shin, and was unable to perform tandem gait. Laboratory tests revealed anemia (hemoglobin 7.2 g/dL) and elevated creatinine (1.49 g/dL). HIV, antinuclear antibodies, antineutrophil cytoplasmic antibodies, hepatitis serologies, rapid plasma reagin, thyroid-stimulating h...

Cerebral small-vessel disease associated with COL4A1 and COL4A2 gene duplications
A nonsmoking woman, aged 44 years, presented with transient right-sided hemiparesis. CT showed leukoencephalopathy without infarction (figure). Blood pressure was normal. Blood count, plasma glucose levels, C-reactive protein, renal/liver function tests, cardiac enzymes, atrial natriuretic factor, HIV/syphilis/hepatitis B and C serology, and lactic acid levels were normal. Low-density lipoprotein (LDL) cholesterol levels were slightly elevated (1.25 g/L). Screening tests for prothrombotic disorders (serum fibrinogen, D-dimer, fibrin degradation products, antithrombin III level, protein C and S level, factor V Leiden, proth...

HCV, but not HIV, is a risk factor for cerebral small vessel disease
Conclusions: This tissue-based analysis of cerebral arteriolar disease demonstrates that HCV constitutes an independent risk, in addition to African American race, hypertension, and cART. Further study is needed to understand what aspects of HCV and cART contribute to cerebrovascular neuropathogenesis.

Glycyrrhizin protects brain against ischemia-reperfusion injury in mice through HMGB1-TLR4-IL-17A signaling pathway.
Abstract High mobility group box 1 (HMGB1)-Toll-like receptor 4 (TLR4) signaling has been recently found to induce interleukin (IL)-17A secretion in drug-induced hepatitis and myocardial I/R injury. The purpose of this study is to evaluate whether HMGB1-TLR4 signaling could induce IL-17A secretion and lead to brain I/R injury. We also sought to investigate whether glycyrrhizin elucidated its neuroprotective effects through HMGB1-TLR4-IL-17A signaling pathway. Various biochemical estimations, neurological status, and assessment of cerebral infarct size were carried out 72h after middle cerebral artery occlusion (MC...

A Case Of Hemophagocytic Lymphohistiocytosis Syndrome In A Patient With Multiple Sclerosis On Fingolimod Therapy. (P2.206)
CONCLUSIONS:As far as we know, this syndrome has never been reported in fingolimod treated patients. EBV reactivation may have been the triggering factor of HLH in our patient. Whether fingolimod contributed to HLH, through a direct mechanism, or indirectly favoring EBV reactivation, remains unknown. Our case highlights the diagnostic challenge of HLH and the need of monitoring and reporting serious adverse events in patients exposed to new IMD. Study Supported by:Disclosure: Dr. Abreu has received personal compensation for activities with Bayer Pharmaceuticals Corporation, Novartis, and Biogen Idec. Dr. Peixoto has nothin...

Neuroprotective effect of bicyclol in rat ischemic stroke: down-regulates TLR4, TLR9, TRAF6, NF-κB, MMP-9 and up-regulates claudin-5 expression.
Conclusions: Bicyclol has neuroprotective effect on cerebral ischemia, and this protection may be through down-regulating TLR4, TLR9, TRAF6, NF-κB, MMP-9 and up-regulating claudin-5 expression. PMID: 23850770 [PubMed - as supplied by publisher]

Risk of Spontaneous Intracranial Hemorrhage in HIV-infected Individuals: A Population-based Cohort Study
Background: We studied the association between HIV infection, antiretroviral medications, and the risk of spontaneous intracranial hemorrhage.Methods: We performed a cohort and nested case control study in an administrative database. We selected all HIV-positive individuals presenting between 1985 and 2007. Each HIV-positive subject was matched with 4 HIV-negative individuals. We used a Poisson regression model to calculate rates of intracranial hemorrhage according to HIV status. We conducted a case -control study nested within the cohort of HIV-positive individuals to look at the effect of antiretroviral medications. Odd...
