Objectives The pathogenesis of idiopathic intracranial hypertension (IIH) is currently unknown and there are speculations about the contribution of some immunologic factors. The aim of this study is to investigate the presence of oligoclonal bands (OCBs) and cerebrospinal fluid (CSF) and/or serum cytokine levels in patients with IIH. Methods Patients fulfilling revised diagnostic criteria for IIH were included. Their demographic, clinical, ophthalmologic and laboratory features were examined. Serum and CSF samples were detected by isoelectric focusing and immunoblotting for OCBs. The samples of IIH patients and control groups were investigated by ELISA for cytokine levels. Results We detected OCBs in eight (30.77%) patients diagnosed with IIH. There were no other obvious clinical and laboratory differences of IIH profiles between the patients with and without OCBs, but frequency of vision loss was significantly higher in the group with OCBs in comparison to OCB negatives ( p = 0.038). Patients with IIH had highly elevated TNF-α, IFN-γ, IL-4, IL-10, IL-12, IL-17 in their sera compared to patients with multiple sclerosis (MS) and healthy controls. Furthermore, all cytokines except TNF-α in the CSF were found significantly higher in IIH patients compared to MS controls. Conclusion The presence of OCBs and elevated cytokine levels in IIH patients may support an immunologic background in the pathophysiological pathway of this disorder.

Abstract Background Idiopathic intracranial hypertension (IIH) is a neurological disorder of unknown pathophysiology with many proposed theories that involve CSF dynamics but recently, involvement of inflammatory and autoimmune processes has been postulated. Objectives To investigate presence of oligoclonal bands (OCB) in cerebrospinal fluid (CSF) and serum cytokine level in patients with IIH. Methods This study was conducted on 27 IIH female patients and 21 age- and sex-matched control groups. Patient and control groups were subjected to measurement of interleukin-4 (IL-4), IL-10, and tumor necrosis factor α (TNF-α) levels in serum, and CSF oligoclonal bands was measured in the IIH patient group. Body mass index (BMI) was measured to both patients and control. Results Serum levels of IL-4, IL-10, and TNF alpha were significantly higher in IIH patients than controls (p <  0.001); 22% of IIH patients had positive OCB in CSF. There was a statistically significant difference regarding TNF-α level in OCB-positive and OCB-negative patients being higher in positive patients. No statistically significant correlation was found between serum levels of IL-4, IL-10, TNF-α, and BMI. Conclusion Autoimmune inflammatory process may play a role in pathophysiology of IIH.

Background Although specific role players are currently unknown, contribution of inflammatory mediators has been suggested in the pathophysiology of idiopathic intracranial hypertension (IIH), which is a disease more prevalent in obese female individuals of childbearing age. We aimed to investigate the levels of adipokines and cytokines to demonstrate possible markers for inflammation that participate in IIH pathophysiology and their association with clinical features of IIH. Methods IIH patients, diagnosed according to the revised criteria, and age-, gender- and body mass index (BMI)-matched healthy controls were enrolled in this study. Serum samples were evaluated for insulin-like growth factor 1, insulin, nesfatin, adiponectin, interleukin (IL)-1β, IL-6, IL-8, leptin, plasminogen activator inhibitor type-1, resistin, tumour necrosis factor-alpha (TNF-α) and monocyte chemotactic protein 1 via enzyme-linked immunosorbent assay or multiplex immunoassays. Results IL-1β level was significantly higher ( p = 0.012), and IL-8 and TNF-α levels were significantly lower in the IIH group ( p < 0.001 and p = 0.008, respectively) compared to the control group. There were no correlations between the cytokine/adipokine levels and age, BMI, disease duration, and cerebrospinal fluid oligoclonal bands. There were also no significant differences in cytokine and adipokine levels between IIH patients regarding visual impairment. However, statistically significant differences were found between IIH patients with relapse versus healthy controls regarding IL-1β ( p = 0.007), IL-8 ( p = 0.001) and TNF-α ( p = 0.017) levels. Other investigated cytokines and adipokines showed no significant alterations in IIH patients investigated in the remission period. Conclusion Altered serum levels of IL-1β, IL-8 and TNF-α seem to be associated with IIH pathogenesis, and these cytokines may be used as prognostic markers in IIH to predict relapse.

ABSTRACT Sputum and serum from patients with active pulmonary tuberculosis (TB), healthy purified protein derivative-positive adults, and patients with bacterial pneumonia were collected to simultaneously assess local immunity in the lungs and peripheral blood. To determine whether cytokine profiles in sputum from TB patients and control subjects were a reflection of its cellular composition, cytospin slides were prepared in parallel and assessed for the presence of relative proportions of epithelial cells, neutrophils, macrophages, and T cells. Gamma interferon (IFN-γ) in sputum from TB patients was markedly elevated over levels for both control groups. With anti-TB therapy, IFN-γ levels in sputum from TB patients decreased rapidly and by week 4 of treatment were comparable to those in sputum from controls. Further, IFN-γ levels in sputum closely followed mycobacterial clearance. Although detected at fourfold-lower levels, IFN-γ immunoreactivities in serum followed kinetics in sputum. TNF-α, interleukin 8 (IL-8) and IL-6 also were readily detected in sputum from TB patients at baseline and responded to anti-TB therapy. In contrast to IFN-γ, however, TNF-α and IL-8 levels also were elevated in sputum from pneumonia controls. These data indicate that sputum cytokines correlate with disease activity during active TB of the lung and may serve as potential early markers for sputum conversion and response to anti-TB therapy.

Background: Serum cytokine levels over the course of HIV infection usually increase with immunosuppression and decrease after antiretroviral treatment (ART). Objectives: The aim of the study is to compare cytokine levels between HIV-infected patients (HIP) and controls and investigate the relationship between CD4+T cell count, HIV-RNA levels, and cytokine levels. Methods: The study subjects comprised ART-naive HIP (n=30) with no comorbidities and age-and sex-matched healthy controls. We measured levels of IL-6, IL-1β, TNF-α, and IFN-γ in serum samples of HIP at the beginning and at month 6 of ART and in controls. Results: The mean age of the study subjects was 38.7 ±10.3 years, with men making up 86.7% of the study subjects (n=26). IL-6, IL-1β, and TNF-α levels were significantly higher in both ART-naive (p<0.001, p=0.002, p=0.001) and ART-experienced HIP (p<0.001) than controls. The IFN-γ level was lower in both ART-naive and ART-experienced HIP compared to controls (p=0.082 and p=0.002). There was a positive correlation between the CD4+T cell count and serum concentration of IFN- γ(r=0.320, p<0.05). While the serum IFN-γ concentration showed a negative correlation with the HIVRNA level(r=-0.412, p<0.001), the serum IL-1β, IL-6, and TNF-α concentrations showed a positive correlation with the HIV-RNA level (r=0.349, p<0.001; r:0.54, p<0.001; r:0.438, p<0.00). Conclusions: Although serum concentrations of IL-6, IL-1β and TNF-α showed a significant decrease after ART, they were still significantly higher than the controls. IFN-γ responded differently to ART compared to the other cytokines, indicating that it may play a distinct and important role in the pathogenesis of HIV infection.

Background: We aimed to investigate the associations of breast cancer (BC) and cancer-related chemotherapies with cytokine levels, and cognitive function. Methods: We evaluated subjective and objective cognitive function in BC patients before chemotherapy and 3~9 months after the completion of chemotherapy. Healthy volunteers without cancer were also compared as control group. Interleukins (IL) 2, 4, 5, 6, 10, 12p70, 13, 17A, 1β, IFNγ, and TNFα were measured. Associations of cancer status, chemotherapy and cytokine levels with subjective and objective cognitive impairments were analyzed using a regression model, adjusting for covariates, including IQ and psychological distress. Results: After adjustment, poorer performance in semantic verbal fluency was found in the post-chemotherapy subgroup compared to controls (p = 0.011, η2 = 0.070); whereas pre-chemotherapy patients scored higher in subjective cognitive perception. Higher IL-13 was associated with lower semantic verbal fluency in the post-chemotherapy subgroup. Higher IL-10 was associated with better perceived cognitive abilities in the pre-chemotherapy and control groups; while IL-5 and IL-13 were associated with lower perceived cognitive abilities in pre-chemotherapy and control groups. Our findings from mediation analysis further suggest that verbal fluency might be affected by cancer status, although mediated by anxiety. Conclusions: Our findings suggest that verbal fluency might be affected by cancer status, although mediated by anxiety. Different cytokines and their interactions may have different roles of neuroinflammation or neuroprotection that need further research.

We describe a case of severe headaches, double vision, and progressive vision loss secondary to a ruptured intracranial cyst (IAC) in a 31-year-old woman with no relevant past medical history. The case is peculiar because drainage of the subdural hygroma led to a minimal improvement in vision with persistent elevated intracranial pressure (ICP). Further exploration revealed transverse sinus stenosis necessitating stenting. Evaluation post-stenting showed marked reduction of ICP and improvement in symptoms. This report underscores the importance of comprehensive work-up and suspicion of multiple underlying etiologies that may be crucial to complete resolution of presenting symptoms in some cases. We provide an overview of the clinical indications and evidence for venous sinus stenting in treating idiopathic intracranial hypertension (IIH).

Abstract Bleaching gel containing hydrogen peroxide (H2O2) cause damages in pulp tissue. This study investigated the action of a topical anti-inflammatory, the Otosporin®, in rats’ bleached teeth with the null hypothesis of which the Otosporin® is no able to minimize the pulp inflammation that bleaching gel generates. The rat’s molars were divided into groups: BLE: bleached (35% H2O2 concentration /single application of 30 min); BLE-O: bleached followed by Otosporin® (10 min); and control: placebo gel. In the second day after dental bleaching, the rats were killed, and the jaws were processed for hematoxylin-eosin and immunohistochemistry analysis for tumor necrosis factor alpha (TNF-α), interleukin (IL)-6 and IL-17. The data collected were subjected to Kruskal-Wallis and Dunn statistical tests with at a 5% level of significance (p<0.05). The BLE group had moderate to strong inflammation in the occlusal third of the coronary pulp, with necrotic areas; and BLE-O, mild inflammation (p<0.05). There was a significant difference in the occlusal and middle thirds of the coronary pulp between the BLE with BLE-O and control groups (p<0.05). There was no difference in the cervical third (p>0.05). The BLE group had a high immunoexpression of TNF-α than BLE-O and control groups (p<0.05), with moderate and mild immunoexpression, respectively. Regarding IL-6 and IL-17, the BLE group had higher immunoexpression than control (p<0.05); the BLE-O was similar to the control (p>0.05). The topical anti-inflammatory Otosporin® can reduce pulp inflammation after dental bleaching in the rat teeth.

External Lumbar Drainage

OBJECTIVE Pediatric idiopathic intracranial hypertension (IIH) is characterized by increased intracranial pressure despite normal cerebrospinal fluid and neuroimaging findings. Initial management is typically medical; however, nearly 10% of children will eventually require surgery for persistent headache and/or vision loss. External lumbar drainage, which is a considerably safer treatment option, has not been adequately analyzed in children with medically refractory IIH. METHODS The authors conducted a single-institution retrospective analysis of children with medically refractory IIH who had undergone external lumbar drain (ELD) placement because of worsening papilledema, reflected as increased retinal nerve fiber layer (RNFL) thickness on optical coherence tomography (OCT) testing. The main outcome measures were effects of external lumbar drainage on papilledema resolution, symptoms, and vision. RESULTS The authors analyzed the medical records of 13 children with IIH (11 girls, mean age 15.0 ± 2.3 years) whose mean CSF opening pressure was 45.5 ± 6.8 cm H2O. In all children, the average global RNFL thickness in both eyes significantly increased at ELD placement (right eye 371.8 ± 150.2 μm, left eye 400.3 ± 96.9 μm) compared with presentation thickness (right eye 301.6 ± 110.40 μm, left eye 350.2 ± 107.7 μm) despite acetazolamide medical therapy (20–30 mg/kg/day), leading to ELD placement after 9.5 ± 6.9 days (range 3–29 days). After ELD insertion, there was headache resolution, gradual and continuous improvement in optic disc thickness, and preservation of good vision. CONCLUSIONS ELD placement in children with medically refractory IIH who demonstrated worsening papilledema with increased RNFL thickening on OCT testing typically results in symptom relief and disc edema resolution with good visual outcome, often preventing the need for additional definitive surgeries that carry greater failure and morbidity risks.

A 44-year-old obese woman presented with decrease in vision in the right eye (RE) for 3 days. She reported a simultaneous onset of holocranial headache that worsened on bending forward. She denied eye pain, pain on eye movements, and other ocular or neurological complaints. On examination, her distance best-corrected visual acuity was counting fingers at 1 m in the RE and 20/20 in the left eye (LE). Colour vision was subnormal in both eyes (BE). There was grade II relative afferent pupillary defect in the RE. Fundus examination showed disc oedema in BE . Visual fields in the LE showed central scotoma extending nasally. A provisional diagnosis of papillitis was considered. However, contrast-enhanced MRI of the brain and orbits showed evidence of elevated intracranial pressure. Cerebrospinal fluid (CSF) opening pressure was 42 cm H2O while rest of the CSF analysis was normal. Diagnosis was revised to fulminant idiopathic intracranial hypertension. Management with medical therapy and urgent thecoperiteoneal shunt improved visual function in BE.

Systemic lupus erythematosus (SLE) is characterized by systemic end-organ damage. We investigated the involvement of IRF5, TLR-7, MECP2, STAT4, and TNFSF4 genes and TNF-α, IFN-γ, IL-2, IL-12, IL-6, and IL-10 cytokines in SLE pathogenesis and in organ damage in Jordanian patients. Blood was collected from 51 patients and 50 controls. Expression levels of SLE genes in PBMCs and cytokine levels were determined using RT-PCR and ELISA, respectively. Expression levels of all genes and levels of TNF-α, IL-12, IL-6, and IL-10 were higher in SLE patients than those in controls (p<0.05), whereas IL-2 level was lower. High STAT4 (α), TNFSF4, and IL-10 levels correlated with cardiovascular damage, and high MECP2 (α) and TNF-α correlated with renal damage. Pulmonary and musculoskeletal damages correlated with high levels of TNFSF4. We concluded that STAT4 and TNFSF4 genes with TNF-α and IL-10 cytokines could be used as biomarkers to assess SLE activity and manage treatment.
