Lessons from studies of antigen-specific T cell responses in Multiple Sclerosis

Multiple Sclerosis (MS) is considered a T cell-mediated autoimmune disease of central nervous system myelin. Based on elegant experiments in an animal model of MS, experimental allergic encephalomyelitis (EAE), a number of myelin proteins and peptides derived from these can induce inflammatory demyelinating lesions. Recent studies with transgenic mice expressing human HLA-DR molecules and a myelin basic protein (MBP)-specific T cell receptor as well as data from a phase II clinical trial with an altered peptide ligand based on MBP peptide (83-99) provide convincing evidence that the pathogenetic concepts which largely stem from the above EAE studies are valid in MS, too.     

Immune responses against SARS-coronavirus nucleocapsid protein induced by DNA vaccine

The nucleocapsid （N） protein of SARS-coronavirus （SARS-CoV） is the key protein for the formation of the helical nucleocapsid during virion assembly. This protein is believed to be more conserved than other proteins of the virus, such as spike and membrane glycoprotein. In this study, the N protein of SARS-CoV was expressed in Escherichia coli DHSalpha and identified with pooled sera from patients in the convalescence phase of SARS. A plasmid pCI-N, encoding the full-length N gene of SARS-CoV, was constructed. Expression of the N protein was observed in COS1 cells following transfection with pCI-N. The immune responses induced by intramuscular immunization with pCI-N were evaluated in a murine model. Serum anti-N immunoglobutins and splenocytes proliferative responses against N protein were observed in immunized BALB/c mice. The major immunoglobulin G subclass recognizing N protein was immunoglobulin G2a, and stimulated splenocytes secreted high levels of gamma interferon and IL-2 in response to N protein. More importantly, the immunized mice produced strong delayed-type hypersensitivity （DTH） and CD^8＋ CTL responses to N protein.     

How to participate in a multiple sclerosis clinical trial

MR imaging has made a significant contribution to the understanding of the natural history of multiple sclerosis (MS). MR imaging is an important technique for investigating the pathologic process in the MS patient's brain and spinal cord, and it is now considered an essential part of all clinical trials being performed on new agents in the treatment of MS. This article provides an overview for those wishing to become involved in MS clinical research. Discussion includes the use of conventional and newer MR imaging techniques in clinical trials, current thoughts regarding the role of MR imaging as a surrogate outcome measure, and various types of trial designs.     

DSM-5 Trichotillomania: Perception of Adults With Trichotillomania After Psychosocial Treatment

Objective: Trichotillomania (TTM) is associated with significant embarrassment and is viewed negatively by others. A potentially important outcome variable that is often overlooked in treatment for TTM is appearance and social perception. Method: The present study tested whether participants in a randomized controlled trial (RCT) of psychotherapy for TTM are viewed more positively by others. All participants in the trial were photographed at baseline and posttreatment. Three treatment responders and three treatment nonresponders were selected randomly for the present study. Several healthy controls were also photographed in a similar manner. Undergraduate college students (N = 245) assessed whether they would reject the person socially, whether the individual has a psychological or medical problem, and attractiveness. Results: Individuals with TTM were viewed more negatively than healthy controls at baseline, but treatment responders showed positive improvements on all perceptions relative to nonresponders. While treatment responders were still perceived more poorly than controls on social rejection and perceptions of problems at posttreatment, responders where rated no differently than controls on attractiveness at posttreatment. Conclusions: The results suggest that persons with TTM who respond to treatment are rated by others as significantly improved in appearance, but they might be still stigmatized or socially rejected.     

Association Between Achieving Inpatient Glycemic Control and Clinical Outcomes in Hospitalized Patients With COVID-19: A Multicenter,Retrospective Hospital-Based Analysis

OBJECTIVEDiabetes and hyperglycemia are important risk factors for poor outcomes in hospitalized patients with coronavirus disease 2019 (COVID-19). We hypothesized that achieving glycemic control soon after admission, in both intensive care unit (ICU) and non-ICU settings, could affect outcomes in patients with COVID-19.RESEARCH DESIGN AND METHODSWe analyzed pooled data from the Glytec national database including 1,544 patients with COVID-19 from 91 hospitals in 12 states. Patients were stratified according to achieved mean glucose category in mg/dL (≤7.77, 7.83–10, 10.1–13.88, and >13.88 mmol/L; ≤140, 141–180, 181–250, and >250 mg/dL) during days 2–3 in non-ICU patients or on day 2 in ICU patients. We conducted a survival analysis to determine the association between glucose category and hospital mortality.RESULTSOverall, 18.1% (279/1,544) of patients died in the hospital. In non-ICU patients, severe hyperglycemia (blood glucose [BG] >13.88 mmol/L [250 mg/dL]) on days 2–3 was independently associated with high mortality (adjusted hazard ratio [HR] 7.17; 95% CI 2.62–19.62) compared with patients with BG <7.77 mmol/L (140 mg/dL). This relationship was not significant for admission glucose (HR 1.465; 95% CI 0.683–3.143). In patients admitted directly to the ICU, severe hyperglycemia on admission was associated with increased mortality (adjusted HR 3.14; 95% CI 1.44–6.88). This relationship was not significant on day 2 (HR 1.40; 95% CI 0.53–3.69). Hypoglycemia (BG <70 mg/dL) was also associated with increased mortality (odds ratio 2.2; 95% CI 1.35–3.60).CONCLUSIONSBoth hyperglycemia and hypoglycemia were associated with poor outcomes in patients with COVID-19. Admission glucose was a strong predictor of death among patients directly admitted to the ICU. Severe hyperglycemia after admission was a strong predictor of death among non-ICU patients.     

Nosocomial and community acquired uropathogenic isolates of Proteus mirabilis and antimicrobial susceptibility profiles at a university hospital in Sub–Saharan Africa

ObjectiveTo ascertain antimicrobial susceptibility profile of Proteus mirabilis (P. mirabilis) from clinical urine specimens at a university hospital in the spate of its recorded increasing resistance patterns.MethodsThe study was retrospective in nature. Data generated from urine cultures of patients at University of Calabar Teaching Hospital for a period of five years (2004–2009) were compiled. Relevant information obtained were age and gender of patients, organisms recovered and their antibiotic susceptibility patterns. P. mirabilis was identified using standard laboratory procedures.ResultsP. mirabilis showed the highest resistance against ampicillin, cloxacillin, amoxicillin, tetracycline, co-trimoxazole, erythromycin and chloramphenicol (100%–37.2%) while colistin, ofloxacin, ciprofloxacin, ceftriaxone, nalidixic acid and nitrofurantoin recorded the highest activity (59.1%–96.9%) with no drug recording 100% activity. The resistance of the nosocomial isolates of the organism were significantly higher than the community acquired isolates against that of the common antibiotics in use (P<0.05).ConclusionsExtreme caution should be exercised in antibiotic administration in hospital setting and the potential benefits adequately assessed while control of nosocomial infections be given a priority so as to limit the spread of resistant bacteria.     

The Role of Individual and Neighborhood Factors: HIV Acquisition Risk Among High-Risk Populations in San Francisco

We examined socioeconomic status and social and sexual network factors and their relationship to HIV acquisition risk among HIV-negative Black MSM (BMSM), White MSM (WMSM) and transfemales (male to female transgenders). Geographic analysis examined residential patterns and neighborhood patterns of HIV prevalence in San Francisco. Factors associated with engaging in more episodes of potentially HIV serodiscordant unprotected receptive anal intercourse were analyzed. Transfemales and BMSM were more likely to live in areas of higher HIV prevalence and lower income compared to WMSM. BMSM and transfemales had lower socioeconomic scores (SES) scores compared to WMSM. BMSM were more likely to report serodiscordant partnerships and higher numbers of potentially serodiscordant unprotected sex acts. Decreasing individual SES did not predict serodiscordant partnerships in any group. Increasing neighborhood HIV prevalence predicted an increase in the number of potentially serodiscordant unprotected sex acts among transfemales and BMSM but only significantly so for transfemales. Prevention interventions must consider neighborhood HIV prevalence, and HIV prevalence in social/sexual networks, in addition to considering individual level behavior change or poverty reduction.
