Abstract

The SENTINEL study showed that the addition of natalizumab improved outcomes for patients with relapsing multiple sclerosis (MS) who had experienced disease activity while receiving interferon beta-1a (IFNbeta-1a) alone. Previously unreported secondary and tertiary magnetic resonance imaging (MRI) measures are presented here. Patients received natalizumab 300 mg (n=589) or placebo (n=582) intravenously every 4 weeks plus IFNbeta-1a 30 microg intramuscularly once weekly. Annual MRI scans allowed comparison of a range of MRI end points versus baseline. Over 2 years, 67% of patients receiving natalizumab plus IFNbeta-1a remained free of new or enlarging T2-lesions compared with 30% of patients receiving IFNbeta-1a alone. The mean change from baseline in T2 lesion volume over 2 years decreased in patients receiving natalizumab plus IFNbeta-1a and increased in those receiving IFNbeta-1a alone (-277.5mm(3) versus 525.6mm(3); p0.001). Compared with IFNbeta-1a alone, add-on natalizumab therapy resulted in a smaller increase in mean T1-hypointense lesion volume after 2 years (1821.3mm(3) versus 2210.5mm(3); p0.001), a smaller mean number of new T1-hypointense lesions over 2 years (2.3 versus 4.1; p0.001), and a slower rate of brain atrophy during the second year of therapy (-0.31% versus -0.40%; p=0.020). Natalizumab add-on therapy reduced gadolinium-enhancing, T1-hypointense, and T2 MRI lesion activity and slowed brain atrophy progression in patients with relapsing MS who experienced disease activity despite treatment with IFNbeta-1a alone.

Abstract

BACKGROUND: The aim of the Betaferon Efficacy Yielding Outcomes of a New Dose (BEYOND) trial was to compare the efficacy, safety, and tolerability of 250 microg or 500 microg interferon beta-1b with glatiramer acetate for treating relapsing-remitting multiple sclerosis. METHODS: Between November, 2003, and June, 2005, 2447 patients with relapsing-remitting multiple sclerosis were screened and 2244 patients were enrolled in this prospective, multicentre, randomised trial. Patients were randomly assigned 2:2:1 by block randomisation with regional stratification to receive one of two doses of interferon beta-1b (250 microg or 500 microg) subcutaneously every other day or 20 mg glatiramer acetate subcutaneously every day. The primary outcome was relapse risk, defined as new or recurrent neurological symptoms separated by at least 30 days from the preceding event and that lasted at least 24 h. Secondary outcomes were progression on the expanded disability status scale (EDSS) and change in T1-hypointense lesion volume. Clinical outcomes were assessed quarterly for 2.0-3.5 years; MRI was done at screening and annually thereafter. Analysis was by per protocol. This study is registered, number NCT00099502. FINDINGS: We found no differences in relapse risk, EDSS progression, T1-hypointense lesion volume, or normalised brain volume among treatment groups. Flu-like symptoms were more common in patients treated with interferon beta-1b (p

Abstract

Objective: To determine the incidence and clinical effects of antibodies that develop during treatment with natalizumab. Methods: In two randomized, double-blind, placebo-controlled studies (natalizumab safety and efficacy in relapsing remitting multiple sclerosis [MS, AFFIRM] and safety and efficacy of natalizumab in combination with interferon β-1a [INFβ1a] in patients with relapsing remitting MS [SENTINEL]) of patients with relapsing multiple sclerosis, blood samples were obtained at baseline and every 12 weeks to determine the presence of antibodies against natalizumab. Antibodies to natalizumab were measured using an ELISA. Patients were categorized as “transiently positive” if they had detectable antibodies (≥0.5 μg/mL) at a single time point or “persistently positive” if they had antibodies at two or more time points ≥6 weeks apart. Results: In the AFFIRM study, antibodies were detected in 57 of 625 (9%) of natalizumab-treated patients: Twenty (3%) were transiently positive and 37 (6%) were persistently positive. Persistently positive patients showed a loss of clinical efficacy as measured by disability progression ( p ≤ 0.05), relapse rate ( p = 0.009), and MRI ( p ≤ 0.05) compared with antibody-negative patients. In transiently positive patients, full efficacy was achieved after approximately 6 months of treatment, the time when patients were becoming antibody negative. The incidence of infusion-related adverse events was significantly higher in persistently positive patients. Results of SENTINEL were similar to AFFIRM, except with regard to sustained disability progression; differences between persistently positive and antibody-negative patients were not statistically significant. Conclusions: The incidence of persistent antibody positivity associated with natalizumab is 6%. Reduced clinical efficacy is apparent in persistently positive patients. Patients with a suboptimal clinical response or persistent infusion-related adverse events should be considered for antibody testing.

Abstract

Objective To report the relationship between disease activity and health-related quality of life (HRQoL) in relapsing multiple sclerosis, and the impact of natalizumab. Methods HRQoL data were available from 2,113 multiple sclerosis patients in natalizumab clinical studies. In the Natalizumab Safety and Efficacy in Relapsing Remitting Multiple Sclerosis (AFFIRM) study, patients received natalizumab 300mg (n = 627) or placebo (n = 315); in the Safety and Efficacy of Natalizumab in Combination with Interferon Beta-1a in Patients with Relapsing Remitting Multiple Sclerosis (SENTINEL) study, patients received interferon beta-1a (IFN-β-1a) plus natalizumab 300mg (n = 589), or IFN-β-1a plus placebo (n = 582). The Short Form-36 (SF-36) and a subject global assessment visual analog scale were administered at baseline and weeks 24, 52, and 104. Prespecified analyses included changes from baseline to week 104 in SF-36 and visual analog scale scores. Odds ratios for clinically meaningful improvement or worsening on the SF-36 Physical Component Summary (PCS) and Mental Component Summary were calculated. Results Mean baseline SF-36 scores were significantly less than the general US population and correlated with Expanded Disability Status Scale scores, sustained disability progression, relapse number, and increased volume of brain magnetic resonance imaging lesions. Natalizumab significantly improved SF-36 PCS and Mental Component Summary scores at week 104 in AFFIRM. PCS changes were significantly improved by week 24 and at all subsequent time points. Natalizumab-treated patients in both studies were more likely to experience clinically important improvement and less likely to experience clinically important deterioration on the SF-36 PCS. The visual analog scale also showed significantly improved HRQoL with natalizumab. Interpretation HRQoL was impaired in relapsing multiple sclerosis patients, correlated with severity of disease as measured by neurological ratings or magnetic resonance imaging, and improved significantly with natalizumab.

Abstract

Background Interferon beta is used to modify the course of relapsing multiple sclerosis. Despite interferon beta therapy, many patients have relapses. Natalizumab, an α 4 integrin antagonist, appeared to be safe and effective alone and when added to interferon beta-1a in preliminary studies. Methods We randomly assigned 1171 patients who, despite interferon beta-1a therapy, had had at least one relapse during the 12-month period before randomization to receive continued interferon beta-1a in combination with 300 mg of natalizumab (589 patients) or placebo (582 patients) intravenously every 4 weeks for up to 116 weeks. The primary end points were the rate of clinical relapse at 1 year and the cumulative probability of disability progression sustained for 12 weeks, as measured by the Expanded Disability Status Scale, at 2 years. Results Combination therapy resulted in a 24 percent reduction in the relative risk of sustained disability progression (hazard ratio, 0.76; 95 percent confidence interval, 0.61 to 0.96; P = 0.02). Kaplan–Meier estimates of the cumulative probability of progression at two years were 23 percent with combination therapy and 29 percent with interferon beta-1a alone. Combination therapy was associated with a lower annualized rate of relapse over a two-year period than was interferon beta-1a alone (0.34 vs. 0.75, P

24. Cosexuality Reduces Pollen Production and Fitness in Cannabis sativa L.

Author

Wizenberg SB, Muir-Guarnaccia J, and Campbell LG

Abstract

Cannabis sativa L. is cultivated globally for its cannabinoid-dense inflorescences. Commercial preference for sinsemilla has led to the development of methods for producing feminized seeds through cross-pollination of cosexual (masculinized) female plants. Although the induction of cosexuality in Cannabis plants is common, to date, no work has empirically tested how masculinization of female Cannabis plants impacts male flowering, pollen production, pollen fitness, and related life-history trade-offs. Here, we cultivated a population of Cannabis plants (CFX-2) and explored how the route to cosexuality (drought vs. chemical induction) impacted flowering phenology, pollen production, and pollen fitness, relative to unsexual male plants. Unisexual males flowered earlier and longer than cosexual plants and produced 223% more total pollen (F 2,28 = 74.41, p < 0.001), but per-flower pollen production did not differ across reproductive phenotypes (F 2,21 = 0.887, p = 0.427). Pollen viability was 200% higher in unisexual males and drought-induced cosexuals (F 2,36 = 189.70, p < 0.001). Pollen non-abortion rates only differed in a marginally significant way across reproductive phenotypes (F 2,36 = 3.00, p = 0.06). Here, we demonstrate that masculinization of female plants impacts whole-plant pollen production and pollen fitness in Cannabis sativa .

Abstract

Objective: To survey the pattern and benefits of medical cannabis use (MCU) in a cross section of persons with multiple sclerosis (PWMS)., Methods: One hundred and fifteen subjects completed a 36-question survey online or on paper which queried aspects of their use of cannabis, including frequency of use, effect on symptoms, and changes in their use of prescription medications, as well asa number of key demographic variables such as age, gender, disease duration and clinical course, etc. All subjects were treated at a multiple sclerosis (MS) clinic in Connecticut and enrolled in the Connecticut Medical Marijuana Program (CTMMP)., Results: Self-reported benefit from cannabis use for two or more symptoms of MS was associated with relapsing remitting MS (RRMS) vs progressive (PMS) (OR 3.043, 95% CI 1.026-9.028, p=0.038) and less benefit for two or more symptoms for those who required a wheelchair vs. those who ambulated without assistance (OR .246, 95% CI .195-.797, p=0.016). General benefit from cannabis use was reported for mood disorders (p<0.001), insomnia (p<0.001), sensory symptoms, including pain (p<0.001), and muscle cramps and spasms (p<0.001). Furthermore, benefit was also significantly associated with symptom severity in the case of insomnia (OR 9.735, 95% CI 2.751-34.445, p<0.001), and cramps and spasms (OR 5.234, 95% CI 1.261-21.729, p=0.014). A significant proportion of respondents had stopped or reduced prescription medications (86% vs. 55%, p<0.001) as a function of finding cannabis more effective than prescription medications. These included opioids, benzodiazepines, muscle relaxers and other pain medications., Conclusion: MCU among PWMS can lead to the reduction or discontinuation of several categories of prescription medications for symptoms of MS. Persons reporting the most benefit from MCU tended to have a milder form of MS with less disability, in contrast to previous studies. This study confirms the benefit of cannabis in several common MS symptoms, extending these findings to show that benefit can be related to baseline severity of some symptoms., (Copyright © 2021 Elsevier B.V.

Abstract

Alcohol use disorders are associated with high craving and disruption of stress biology, but their role in behavioral alcohol motivation is less clear. We examined the effects of craving and cortisol responses on behavioral alcohol motivation to stress, alcohol cue and neutral-relaxing context cues, in addition to discrete alcohol cues, in demographically matched binge/heavy (BH) and moderate (MD) social drinkers. Subjects participated in a 3-day laboratory experiment of provocation by three personalized guided imagery contexts and discrete alcohol cues followed by the 'alcohol taste test' (ATT) to assess behavioral motivation, as measured by ATT intake. Post-ATT alcohol effects on craving and cortisol responses were also examined. Results indicate BH consumed significantly more alcohol than MD in the ATT. Stress and alcohol cue contexts, relative to neutral, led to significantly greater ATT intake across both groups, which also correlated positively with self-reported alcohol use in past 30 days. Stress and alcohol context and discrete alcohol cues each significantly increased alcohol craving, more so in the BH than MD, and significantly predicted greater ATT intake in BH only. The BH showed significantly lower cortisol responses than MD overall and blunted cortisol responses to cues predicted significantly greater ATT intake in the stress condition for BH and in the alcohol cue condition for MD. Higher ATT intake predicted greater cortisol response and higher craving post-ATT, and these effects were moderated by group status. In sum, findings suggest a role for sensitized context-induced craving and blunted cortisol responses in increased behavioral motivation for alcohol., (© 2018 Society for the Study of Addiction.)

Abstract

Overeating of highly palatable (HP) foods in the ubiquitous HP food cue environment and under stress is associated with weight gain and contributes to the global obesity epidemic. However, subjective and biobehavioral processes that may increase HP overeating are not clear. Using a novel experimental approach, we examined HP food motivation and intake and neuroendocrine responses in the context of food cues, stress and a control neutral relaxing cue exposure in healthy individuals., Methods: Twenty individuals (12 M; 8F; ages 18-45) with body mass index (BMI) in the lean (LN: N = 8; 3/8 female BMI: 18-24.9) or overweight/obese (OW: N = 12; 5/12 female; BMI: 25-37) range were enrolled in a controlled, hospital-based, 3-day laboratory experiment. On each day, subjects were exposed to a brief 5-min individualized guided imagery of stress, food cue or an active neutral-relaxing control cue script, followed by a food snack test (FST), with one imagery condition per day and order of imagery exposure randomized and counterbalanced across subjects. Subjective HP food craving and caloric intake, anxiety, cortisol and total ghrelin was assessed repeatedly during each test day., Results: Significant condition and condition × group effects for food craving, anxiety and HP calorie intake were observed, with food cue relative to neutral condition increasing HP food craving and intake across all subjects (p < .001), but stress relative to neutral condition increased HP food craving and intake in the OW but not LN group (p < .01). Pre-snack increases in food craving after exposure to food cues and to stress predicted greater subsequent HP food intake (p's < 0.01). Furthermore, ghrelin increased in the food cue and stress conditions (p < .01), but stress-induced increases in ghrelin was associated with HP food intake only in the OW/OB condition (p < .01). Finally, cortisol increased during food cue exposure and increased cortisol responses were associated with greater HP food caving and with intake (p's < 0.05)., Conclusions: These findings, while preliminary, validate a laboratory model of HP food motivation and intake and identify specific subjective and neuroendocrine responses that may play a role in HP snacking with implications for weight gain and obesity risk.

Abstract

Fingolimod is an approved therapeutic option for patients with relapsing-remitting multiple sclerosis that primarily functions by sequestering T cells in lymph nodes inhibiting their egress to the central nervous system. However, recent data suggests that Fingolimod may also directly affect the immune cell function. Here we examined the in vivo effects of Fingolimod in modulating the phenotype and function of T cell and Foxp3 regulatory T cell populations in patients with multiple sclerosis under Fingolimod treatment. Besides decreasing the cell numbers in peripheral blood and sera levels of pro-inflammatory cytokines, Fingolimod inhibited the expression of Th1 and Th17 cytokines on CD4 + T cells and increased the expression of exhaustion markers. Furthermore, treatment increased the frequency of regulatory T cells in blood and inhibited the Th1-like phenotype that is characteristic of patients with multiple sclerosis, augmenting the expression of markers associated with increased suppressive function. Overall, our data suggest that Fingolimod performs other important immunomodulatory functions besides altering T cell migratory capacities, with consequences for other autoimmune pathologies characterized by excessive Th1/Th17 responses and Th1-like regulatory T cell effector phenotypes., (Copyright © 2018.

Abstract

Structural neuroimaging studies have provided evidence of differences in local brain volume between cocaine-dependent and healthy control individuals. While sex differences in aetiology, course and brain dysfunction associated with chronic cocaine abuse have been previously documented, evidence of sex-specific differences in brain volume has not been examined thus far. This study examined sex-related differences in grey matter volume between cocaine-dependent and healthy control subjects using voxel-based morphometry. High-resolution T1 structural scans were obtained from 36 inpatient, treatment-engaged 3-week abstinent cocaine-dependent (CD) individuals. Fifty healthy control subjects were also scanned. Segmentation and registration were performed in SPM8, using New Segment and DARTEL, respectively. The whole-brain statistical analysis was conducted in SPM8 using random field-based cluster-size testing and family-wise error rate correction for multiple comparisons. CD patients were found to have less grey matter volume in anterior prefrontal cortex, including frontopolar and orbitofrontal cortices, and a posterior region surrounding the parietal-occipital sulcus. Female CD patients had less grey matter volume than female controls in left inferior frontal gyrus, insula, superior temporal gyrus and hippocampus. Male CD patients had less grey matter in a superior cortical region that included the precentral gyrus and the mid-cingulate. These sex differences in lower grey matter volume add to the evidence from functional neuroimaging for sex-specific differences in the neurophysiological changes associated with chronic cocaine use., (© 2012 The Authors, Addiction Biology © 2012 Society for the Study of Addiction.)

Abstract

Background: Cumulative adversity and stress are associated with risk of psychiatric disorders. While basic science studies show repeated and chronic stress effects on prefrontal and limbic neurons, human studies examining cumulative stress and effects on brain morphology are rare. Thus, we assessed whether cumulative adversity is associated with differences in gray matter volume, particularly in regions regulating emotion, self-control, and top-down processing in a community sample., Methods: One hundred three healthy community participants, aged 18 to 48 and 68% male, completed interview assessment of cumulative adversity and a structural magnetic resonance imaging protocol. Whole-brain voxel-based-morphometry analysis was performed adjusting for age, gender, and total intracranial volume., Results: Cumulative adversity was associated with smaller volume in medial prefrontal cortex (PFC), insular cortex, and subgenual anterior cingulate regions (familywise error corrected, p < .001). Recent stressful life events were associated with smaller volume in two clusters: the medial PFC and the right insula. Life trauma was associated with smaller volume in the medial PFC, anterior cingulate, and subgenual regions. The interaction of greater subjective chronic stress and greater cumulative life events was associated with smaller volume in the orbitofrontal cortex, insula, and anterior and subgenual cingulate regions., Conclusions: Current results demonstrate that increasing cumulative exposure to adverse life events is associated with smaller gray matter volume in key prefrontal and limbic regions involved in stress, emotion and reward regulation, and impulse control. These differences found in community participants may serve to mediate vulnerability to depression, addiction, and other stress-related psychopathology., (Copyright © 2012 Society of Biological Psychiatry.

Whether persistent brain volume deficits in abstinence are predictive of subsequent time to alcohol relapse has not been established. The authors measured gray matter volumes in healthy volunteers and in a sample of treatment-engaged, alcohol-dependent patients after 1 month of abstinence and assessed whether smaller frontal gray matter volume was predictive of subsequent alcohol relapse outcomes., Method: Forty-five abstinent alcohol-dependent patients in treatment and 50 healthy comparison subjects were scanned once using high-resolution (T(1)-weighted) structural MRI, and voxel-based morphometry was used to assess regional brain volume differences between the groups. A prospective study design was used to assess alcohol relapse in the alcohol-dependent group for 90 days after discharge from 6 weeks of inpatient treatment., Results: Significantly smaller gray matter volume in alcohol-dependent patients relative to comparison subjects was seen in three regions: the medial frontal cortex, the right lateral prefrontal cortex, and a posterior region surrounding the parietal-occipital sulcus. Smaller medial frontal and parietal-occipital gray matter volumes were each predictive of shorter time to any alcohol use and to heavy drinking relapse., Conclusions: These findings are the first to demonstrate that gray matter volume deficits in specific medial frontal and posterior parietal-occipital brain regions are predictive of an earlier return to alcohol use and relapse risk, suggesting a significant role for gray matter atrophy in poor clinical outcomes in alcoholism. Extent of gray matter volume deficits in these regions could serve as useful neural markers of relapse risk and alcoholism treatment outcome.

Abstract

Background: The complexity and cost of injection treatment can represent a formidable challenge for patients affected by a chronic illness, particularly those whose treatment is primarily preventative and only modestly effective on the more conspicuous symptomatic aspects of the disease process. The aim of this investigation was to identify which factors most influenced nonadherent behavior with the available disease-modifying injection therapies for multiple sclerosis (MS)., Methods: A multicenter, observational (three-wave) study using surveys was developed and administered to patients with MS through the World Wide Web. Healthcare providers at 17 neurology clinics recruited patients for the study., Results: A total of 798 patients responded to the baseline wave of the study (708 responded to all three waves). The nonadherence rates for all patients (missing one or more injections) across these waves remained relatively stable at 39%, 37%, and 36%, respectively. The most common reason participants listed for missing injections was that they simply forgot to administer the medication (58%). Other factors including injection-site reactions, quality of life, patients' perceptions on the injectable medications, hope, depression, and support were also assessed in relation to adherence., Conclusions: This study characterizes factors that are associated with failure to fully adhere with disease modifying injection therapy for MS and underscores the principles associated with optimizing adherence and its implications for effective treatment of the disease process in MS.

Abstract

An assessment of off-site exposure from spills/releases of toxic chemicals can be conducted by compiling site-specific operational, geographic, demographic, and meteorological data and by using screening-level public-domain modeling tools (e.g., RMP Comp, ALOHA and DEGADIS). In general, the analysis is confined to the following: event-based simulations (allow for the use of known, constant, atmospheric conditions), known receptor distances (on the order of miles or less), short time scale for the distances considered (order of 10's of minutes or less), gently sloping rough terrain, dense and neutrally buoyant gas dispersion, known chemical inventory and infrastructure (used to define source-term), and known toxic endpoint (defines significance). While screening-level models are relatively simple to use, care must be taken to ensure that the results are meaningful. This approach allows one to assess risk from catastrophic release (e.g., via terrorism), or plausible release scenarios (related to standard operating procedures and industry standards). In addition, given receptor distance and toxic endpoint, the model can be used to predict the critical spill volume to realize significant off-site risk. This information can then be used to assess site storage and operation parameters and to determine the most economical and effective risk reduction measures to be applied.

Abstract

Nonionic block copolymers, synthesized from repeating units of oxypropylene and oxyethylene, can be designed so that individual copolymers have unique physical properties with differential levels of adjuvant activity. We have designed high molecular weight block copolymers that spontaneously assemble into 500 nm-3 mum particles when formulated with protein antigens in aqueous solutions at physiological pH. The adjuvant activity of one of these copolymers, termed CRL1005, was compared to selected research adjuvants using ovalbumin (OVA) as the prototype vaccine antigen. Suboptimal doses of OVA were formulated with complete and incomplete. Freund's adjuvant (CFA/IFA), alum Quil-A saponins Ribi Adjuvant System (RAS) or the CRL1005 copolymer and these formulations were used to immunize C57BL/6 mice. The CRL1005 copolymer appeared to be more potent than either Quil-A or alum and comparable to the RAS formulation, based on the numbers of responding mice and the OVA-specific antibody titers. Alum. RAS and Quil-A all augmented the production of IgG1 and IgG2l, similarly whereas only the CFA/IFA boosted IgG2a levels significantly. The effect of adjuvants on relative antibody affinity was more variable with the CRL1005 and CFA/IFA inducing antibodies with the highest affinity scores. This high molecular weight nonionic copolymer is nontoxic in aqueous formulations and should therefore be compatible with a wide variety of protein or polysaccharide vaccine antigens.

Abstract

Mycobacterium avium is one of the most prevalent opportunistic infections in AIDS patients, and neither prophylaxis nor treatment against M. avium is effective. To evaluate host defense mechanisms against mycobacterial infections, studies investigated whether neutrophils from AIDS patients could inhibit the growth of M. avium in vitro and what cytokines enhance neutrophil function against M. avium. Peripheral blood neutrophils from human immunodeficiency virus-negative and AIDS patients were incubated with media, granulocyte colony-stimulating factor (G-CSF), granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin-8, or macrophage-inhibitory proteins and infected with M. avium, and the inhibition of bacterial growth was determined. G-CSF (1000 U/mL) and GM-CSF (2000 U/mL) stimulated neutrophils from AIDS patients to significantly inhibit M. avium growth. These results demonstrate that neutrophils from AIDS patients can respond to exogenously supplied G-CSF or GM-CSF by inhibiting the growth of M. avium.

Abstract

Objective: To determine if the addition of recombinant (r) human interleukin (IL)-12 enhances in vitro proliferative responses to Mycobacterium avium of peripheral blood mononuclear cells (PBMC) from HIV-positive donors with CD4 cell counts < 100 x 10(6)/l., Design and Methods: PBMC proliferative responses to virulent and avirulent serovars of M. avium in the presence and absence of exogenously added IL-12 were determined in 24 HIV-positive and 11 HIV-negative donors by 3H-thymidine uptake assay. Changes in CD4 and CD8 cell populations after IL-12 treatment and M. avium stimulation were analyzed by FACS., Results: IL-12 significantly enhanced proliferation of PBMC to both virulent and avirulent M. avium from all 24 HIV-positive donors (P = 0.0001) although the magnitude varied for each donor. In contrast, addition of IL-12 to PBMC from HIV-negative donors only increased the proliferative responses to the virulent M. avium serovar 4 (P = 0.0044). PBMC from HIV-positive donors in the presence of IL-12 responded better to the avirulent serovar of M. avium than the virulent serovar 4. Proliferative responses of HIV-positive donors to M. avium alone, however, were significantly less (P = 0.0013) than that of HIV-negative donors. Increased proliferative responses of HIV-positive donors were independent of CD4 counts. No significant changes in the ratio of CD4+ to CD8+ T cells occurred in either HIV-positive or negative donors under any culture conditions., Conclusion: In vitro proliferative responses of PBMC from HIV-positive donors to M. avium were significantly enhanced by the addition of human rIL-12, which was not dependent on their CD4 cell counts. The use of IL-12 as an enhancer of cell-mediated immunity in AIDS patients against M. avium infections deserves further study.

Abstract

Objective: Granulomatous angiitis of the central nervous system (CNS) is a rare cause of vasculitis involving the brain and spinal cord and is included in lists of disorders causing strokes. To determine the frequency of strokes (eg, sudden onset of focal symptoms) as a presenting complication and to determine the sensitivity of angiography and other technologies in detecting vasculitis in histologically proved cases of idiopathic granulomatous angiitis of the CNS (IGANS), we reviewed the published literature., Data Sources: A biopsy-proved case of IGANS in a patient presenting without strokes and with a normal angiogram is reported. Additional cases of pathologically proved IGANS where results of angiography or other neuroimaging procedures were available were found by search of MEDLINE and bibliographies of pertinent articles and books., Data Extraction: We compared our case with 39 reported cases of histologically proved granulomatous angiitis of the CNS not associated with Hodgkin's disease, herpes zoster, sarcoidosis, or other proximate cause. We included only those cases that had been evaluated with angiography or other neuroimaging techniques before death or biopsy., Data Synthesis: Analysis of these cases shows that strokes as presenting complications are rare in IGANS. Most patients present with a diffuse encephalopathy and, when focal symptoms develop, they tend to develop gradually. Including our case, 56% of 41 angiograms performed in 31 reported patients with histologically proved IGANS were abnormal, but only 27% were diagnostic for vasculitis., Conclusions: We conclude that stroke is uncommon as a presenting complaint in IGANS and angiography is insensitive as a screening test for these patients.

Abstract

Five cases of bacteremic infections due to Haemophilus influenzae type f in adults are described, and previous reports of type f disease in nonpediatric patients are reviewed. Respiratory tract infections were most common in our series (two cases of pneumonia, one of epiglottitis, and one of nosocomial septicemia probably resulting from aspiration pneumonitis). All of these patients had factors predisposing them to respiratory tract infections, e.g., neurologic disease, congestive heart failure, or cigarette smoking. A fifth patient, who was bacteremic without an apparent primary focus, had dysgammaglobulinemia. Six episodes of bacteremia occurred in five patients; 11 of 13 cultures of blood obtained before parenteral antibiotic therapy were positive. All isolates were biotype I and susceptible to ampicillin. Antibiotic therapy was curative in cases of proved respiratory tract infection but failed in the setting of nosocomial septicemia, perhaps because of delayed initiation. The brevity of antibiotic treatment of the cryptogenic bacteremia permitted infection of a prosthetic vascular graft and recurrent bacteremia. Graft removal and repeated antibiotic therapy were curative.
