Introduction: Shellfish allergy is an important cause of food allergies worldwide. Both in vivo and in vitro diagnostics failure nowadays is caused by the poor quality of the extracts associated with the scarce availability of allergenic molecules in the market. It is known that not all patients with shellfish allergies experience adverse reactions to mollusks. It is still unclear how to detect and diagnose these patients correctly., Aim: To investigate the features of shrimp-allergic patients either reactive or tolerant to mollusks, with the currently available diagnostic methods., Methods: Nineteen centers, scattered throughout Italy, participated in the real-life study, enrolling patients allergic to shrimp with or without associated reactions to mollusks. Patients underwent skin tests using commercial extracts or fresh raw and cooked shrimp and mollusks, and IgE reactivity to currently available allergenic extracts and molecules was measured in vitro ., Results: Two hundred and forty-seven individuals with a self reported adverse reactions to shrimp participated in the study; of these 47.8% reported an adverse reaction to mollusks ingestion (cephalopod and/or bivalve). Neither of the tests used, in vivo nor in vitro , was able to detect all selected patients. Accordingly, a great heterogeneity of results was observed: in vivo and in vitro tests agreed in 52% and 62% of cases. Skin tests were able to identify the mollusk reactors (p < 0.001), also using fresh cooked or raw food (p < 0.001). The reactivity profile of mollusk reactors was dominated by Pen m 1, over Pen m 2 and Pen m 4 compared to tolerant subjects, but 33% of patients were not detected by any of the available molecules. Overall, a higher frequency of IgE rectivity to shrimp was recorded in northern Italy, while mollusk reactivity was more frequent in the center-south., Conclusion: The current diagnostic methods are inadequate to predict the cross-reactivity between crustaceans and mollusks. The detection of mollusks hypersensitivity should still rely on skin tests with fresh material. The exclusion of mollusks from shrimp allergic patients' diets should occur when clinical history, available diagnostic instruments, and/or tolerance tests support such a decision., (© 2022 The Author(s).)

Background and Aims: Diagnosis of fish may represent an important challenge for the allergists. This study aimed to evaluate the diagnostic sensitivity of an in vitro multiplex assay using a comprehensive panel of fish allergens and the cross-reactivity patterns between different molecular components., Methods: 56 subjects with fish allergy were enrolled. All patients underwent specific IgE measurement using the Allergy Explorer-Alex 2™ multiplex assay (Macroarray Diagnostics, Vienna, Austria) RESULTS: The single ß-parvalbumins Clu h 1, Cyp c 1, Gad m 1, Sal s 1, Sco s 1, Thu a 1 and Xyp g 1 scored positive in 75.0%, 67.8%, 62.5%, 80.3%,80.3%, 78.8% and 73,2% patients, respectively. 14.3% scored positive for the α-parvalbumin (Raj c-parvalbumin), and 16.1% for the aldolase + enolase (Gad m 2 + 3) components. 92.8% reacted to at least one ß-parvalbumin and 96.4% to at least one of the allergens tested. Overall sensitivity was higher than that obtained using commercial extracts of cod, salmon and tuna for skin prick test (75.8%) and IgE detection (92.3%)., Conclusions: The Alex 2 showed high diagnostic sensitivity and it might be used as an additional assay to investigate the cross-reactivity patterns between different molecular components, looking for potentially safe fish species., (Copyright © 2022 Elsevier B.V.

Background: Mobile health technologies enable allergists to monitor disease trends by collecting daily patient-reported outcomes of allergic rhinitis. To this end, patients with allergies are usually required to enter their symptoms and medication repetitively over long time periods, which may present a risk to data completeness and quality in the case of insufficient effort reporting. Completeness of patient's recording is easily measured. In contrast, the intrinsic quality and accuracy of the data entered by the patients are more elusive., Objective: The aim of this study was to explore the association of adherence to digital symptom recording with a predefined set of parameters of the patient-generated symptom and medication scores and to identify parameters that may serve as proxy measure of the quality and reliability of the information recorded by the patient., Methods: The @IT.2020 project investigates the diagnostic synergy of mobile health and molecular allergology in patients with seasonal allergic rhinitis. In its pilot phase, 101 children with seasonal allergic rhinitis were recruited in Rome and instructed to record their symptoms, medication intake, and general conditions daily via a mobile app (AllergyMonitor) during the relevant pollen season. We measured adherence to daily recording as the percentage of days with data recording in the observation period. We examined the patient's trajectories of 3 disease indices (Rhinoconjunctivitis Total Symptom Score [RTSS], Combined Symptom and Medication Score [CSMS], and Visual Analogue Scale [VAS]) as putative proxies of data quality with the following 4 parameters: (1) intravariation index, (2) percentage of zero values, (3) coefficient of variation, and (4) percentage of changes in trend. Lastly, we examined the relationship between adherence to recording and each of the 4 proxy measures., Results: Adherence to recording ranged from 20% (11/56) to 100% (56/56), with 64.4% (65/101) and 35.6% (36/101) of the patients' values above (highly adherent patients) or below (low adherent patients) the threshold of 80%, respectively. The percentage of zero values, the coefficient of variation, and the intravariation index did not significantly change with the adherence to recording. By contrast, the proportion of changes in trend was significantly higher among highly adherent patients, independently from the analyzed score (RTSS, CSMS, and VAS)., Conclusions: The percentage of changes in the trend of RTSS, CSMS, and VAS is a valuable candidate to validate the quality and accuracy of the data recorded by patients with allergic rhinitis during the pollen season. The performance of this parameter must be further investigated in real-life conditions before it can be recommended for routine use in apps and electronic diaries devoted to the management of patients with allergic rhinitis., (©Stephanie Dramburg, Serena Perna, Marco Di Fraia, Salvatore Tripodi, Stefania Arasi, Sveva Castelli, Danilo Villalta, Francesca Buzzulini, Ifigenia Sfika, Valeria Villella, Ekaterina Potapova, Maria Antonia Brighetti, Alessandro Travaglini, Pierluigi Verardo, Simone Pelosi, Paolo Maria Matricardi.

Background: Patient-generated symptom and medication scores are essential for diagnostic and therapeutic decisions in seasonal allergic rhinitis (SAR). Previous studies have shown solid consistencies between different scores at population level in real-life data and trials. For clinicians, the evaluation of individual data quality over time is essential to decide whether to rely on these data in clinical decision-making., Objective: To analyze the consistency of different symptom (SS) and symptom medication scores (SMSs) at individual level in two study cohorts with different characteristics and explore individual patient trajectories over time., Methods: Within the pilot phase of the @IT.2020 project on diagnostic synergy of mobile health and molecular IgE assessment in patients with SAR, we analyzed data of 101 children and 93 adults with SAR and instructed them to record their symptoms and medication intake daily via the mobile app AllergyMonitor®. We then assessed the correlation between different SMS and a visual analogue scale (VAS) on the impact of allergy symptoms on daily life at population and individual level., Results: At population level, the Rhinoconjunctivitis total symptom score (RTSS) correlated better with VAS than the combined symptom and medication score (CSMS). At individual level, consistency among RTSS and VAS was highly heterogeneous and unrelated to disease severity or adherence to recording. Similar heterogeneity was observed for CSMS and VAS., Conclusions: The correlation of clinical information provided by different disease severity scores based on data collected via electronic diaries (e-diaries), is sufficient at population level, but broadly heterogeneous for individual patients. Consistency of the recorded data must be examined for each patient before remotely collected information is used for clinical decision making., Competing Interests: Paolo Matricardi reports grants and personal fees from TPS Software Production, outside the submitted work.

Background: Clinically complex phenotypes require more and more sophisticated and comprehensive diagnostic approaches, able to discriminate genuine sensitizations from cross-reactivity. Interpretative complexity of multiplex diagnostic arrays has somewhat limited their diffusion. This study compares two currently available methods, namely ISAC ® test and ALEX2 ® test., Methods: In total, 140 allergic individuals, with a history of atopic dermatitis, adverse food reactions, allergic rhinitis and/or bronchial asthma were studied by Allergy Explorer-ALEX2 ® macroarray and ImmunoCAP ISAC112 ® . Lin's concordance correlation coefficient, intraclass correlation coefficient and Bland-Altman plots were used to verify the agreement between continuous values. Cohen's kappa coefficient (k) was assessed for the molecules available in both tests. The degree of relationship was analysed using Spearman's correlation (quantitative variables) and Pearson's χ 2 or Fisher's exact test (categorical variables)., Results: A substantial agreement (κ = 0.795) was observed between the two methods with 94,3% concordant results when results were dichotomized as negative or positive, but if double-negative results were discarded, the agreement dropped to 71%. Conversely, little or no concordance was observed comparing raw data. Considering the 102 molecules shared by both systems, 28/102 (27%) showed an almost perfect agreement (k > 0.81), and concordance was good (k > 0.61) in a further 32 (31%) cases. A perfect to substantial agreement was observed by comparing species-specific aeroallergens. Heterogeneous results emerged comparing panallergens (co-recognition ranging from 30% for tropomyosin/serum albumins to 70% for PR-10/profilin). The correlation among LTP, profilin and PR-10 assayed with ISAC ® was better than ALEX2 ® , but the latter identified more positive cases due to the wider number of molecules available. The CCD blocker provided by ALEX ® test abolishes the carbohydrate determinants signal in 60% of the 33 cases reactive to MUXF3 on the ISAC ® test., Conclusion: Despite the excellent concordance of the species-specific markers, the analysis of the panallergens provided in both methods suggests a better performance of the ISAC ® test on those components, while the ALEX2 ® test, which includes a larger number of allergens, allowing a broader molecular detection., (© 2021 John Wiley & Sons Ltd.)

Background and Objectives: Peach gibberellin-regulated protein (peamaclein) has recently emerged as a relevant food allergen in cypress pollen-hypersensitive patients. Objective: We investigated monosensitization to peamaclein among Italian cypress pollen-allergic patients., Material and Methods: A total of 835 cypress pollen-hypersensitive patients from 28 Italian allergy centers underwent a thorough work-up to determine food-allergic reactions and performed skin prick testing with a commercial peach extract containing peamaclein. IgE to rPru p 3 was measured in peach reactors, and those with negative results were enrolled as potentially monosensitized to peamaclein. IgE reactivity to rPru p 7 was evaluated using immunoblot and an experimental ImmunoCAP with rPru p 7., Results: Skin prick tests were positive to peach in 163 patients (19.5%); however, 127 (77.9%) were excluded because they reacted to Pru p 3. Twenty-four patients (14.7%) corresponding to 2.8% of the entire study population) were considered potentially monosensitized to peamaclein. No geographic preference was observed. Seventeen of the 24 patients (70.8%) had a history of food allergy, mainly to peach (n=15). Additional offending foods included other Rosaceae, citrus fruits, fig, melon, tree nuts, and kiwi. On peach immunoblot, only 3 of 18 putative peamaclein-allergic patients reacted to a band at about 7 kDa; an additional 4 patients reacted at about 50-60 kDa. Ten of 18 patients (56%) had a positive result for Pru p 7 on ImmunoCAP., Conclusion: Allergy and sensitization to peamaclein seem rare in Italy. Most patients react to peach, although other Rosaceae fruits and several citrus fruits may also be offending foods. Peach and cypress pollen probably also share cross-reacting allergens other than peamaclein.

Background: Complete diagnosis and therapy of seasonal allergic rhinoconjunctivitis require evidence that exposure to the sensitizing pollen triggers allergic symptoms. Electronic clinical diaries, by recording disease severity scores and pollen exposure, can demonstrate this association. However, patients who spontaneously download an e-diary app show very low adherence to their recording., Objective: The objective of our study was to assess adherence of patients with seasonal allergic rhinitis to symptom recording via e-diary explicitly prescribed by an allergist within a blended care approach., Methods: The @IT-2020 project is investigating the diagnostic synergy of mobile health and molecular allergology in patients with seasonal allergic rhinitis. In the pilot phase of the study, we recruited Italian children (Rome, Italy) and adults (Pordenone, Italy) with seasonal allergic rhinitis and instructed them to record their symptoms, medication intake, and general conditions daily through a mobile app (Allergy.Monitor) during the relevant pollen season., Results: Overall, we recruited 101 Italian children (Rome) and 93 adults (Pordenone) with seasonal allergic rhinitis. Adherence to device use slowly declined during monitoring in 3 phases: phase A: first week, ≥1267/1358, 90%; phase B: second to sixth week, 4992/5884, 80% to 90%; and phase C: seventh week onward, 2063/2606, 70% to 80%. At the individual level, the adherence assessed in the second and third weeks of recording predicted with enough confidence (Rome: Spearman ρ=0.75; P<.001; Pordenone: ρ=0.81; P<.001) the overall patient adherence to recording and was inversely related to postponed reporting (ρ=-0.55; P<.001; in both centers). Recording adherence was significantly higher during the peak grass pollen season in Rome, but not in Pordenone., Conclusions: Adherence to daily recording in an e-diary, prescribed and motivated by an allergist in a blended care setting, was very high. This observation supports the use of e-diaries in addition to face-to-face visits for diagnosis and treatment of seasonal allergic rhinitis and deserves further investigation in real-life contexts., (©Marco Di Fraia, Salvatore Tripodi, Stefania Arasi, Stephanie Dramburg, Sveva Castelli, Danilo Villalta, Francesca Buzzulini, Ifigenia Sfika, Valeria Villella, Ekaterina Potapova, Serena Perna, Maria Antonia Brighetti, Alessandro Travaglini, Pierluigi Verardo, Simone Pelosi, Anna Maria Zicari, Paolo Maria Matricardi.

Background: Molecular allergy has significantly improved the quality of allergy diagnosis; however, the positioning of singleplex and multiplex assays in the diagnostic algorithm is still a matter of debate., Methods: Aim of the study was to test the analytical performance of the recently commercialized Allergy Explorer-ALEX® in a selected population (105 allergic patients and 15 negative controls), comparing it with the reference ImmunoCAP® method and with skin prick test (SPT)., Results: Inter-assay qualitative comparison showed a substantial agreement between ALEX® and SPT (k = 0.64). A substantial agreement between ALEX® and ImmunoCAP® was shown on the detection of IgE to extracts (k = 0.64 for inhalants and k = 0.51 for food allergens), whereas a higher agreement was shown on detection of molecular components (k = 0.92 for inhalants and k = 0.72 for food allergens). Quantitative comparison showed a poor correlation between ALEX® and ImmunoCAP®., Conclusion: The simultaneous detection of both extracts and molecular components with ALEX® assay can potentially overcome some of the major limitations of the multiplex assay currently in use. However, before using ALEX® as routine method, the analytical performance (in particular for extracts) needs to be further investigated on a larger scale., (Copyright © 2019.

Tumor necrosis factor alpha (TNF-α) is a pleiotropic cytokine that plays a central role in the immune system functioning and in the pathogenesis of rheumatoid arthritis (RA). TNF-α inhibition has been demonstrated effective to treat RA; however, response to anti-TNF-α therapies is heterogeneous, with roughly one-third of patients not achieving disease control. Identification of a biological marker to assess the effectiveness of TNF-α inhibition may help to discriminate patients with a reduced response to anti-TNF-α agents. The aim of this study was to assess whether anti-TNF-α treatment was able to modify the cytokine network interfering with interferon gamma (INFγ) release after phytohemagglutinin (PHA) stimulation of peripheral blood mononuclear cells (PBMCs) from RA patients, according to disease activity. We found that RA patients with active disease had low release of INFγ after PHA stimulation, but anti-TNF-α agents were able to modify INFγ production. In anti-TNF-α responders, we observed a higher release of INFγ, achieving levels comparable with those seen in healthy subjects. The ability of PBMCs from RA patients to release INFγ may serve as a biomarker of disease activity and response to anti-TNF-α. Larger studies are needed to validate these data., (© 2014 Wiley Periodicals, Inc.)

Schwannomas are benign encapsulated neoplasms of the peripheral nerve sheath. Clinical diagnosis is often difficult, and final diagnosis is usually based on histopathological findings. Imaging techniques, such as magnetic resonance imaging and ultrasonography, can be optimized to improve assessment prior to surgical treatment. The present case demonstrates that high-resolution sonography can be useful in assessing the underlying cause of median nerve pathology.

Introduction: In recent years, there has been an increased demand for computer-aided diagnosis (CAD) tools to support clinicians in the field of indirect immunofluorescence. To this aim, academic and industrial research is focusing on detecting antinuclear, anti-neutrophil, and anti-double-stranded (anti-dsDNA) antibodies. Within this framework, we present a CAD system for automatic analysis of dsDNA antibody images using a multi-step classification approach. The final classification of a well is based on the classification of all its images, and each image is classified on the basis of the labeling of its cells., Methods: We populated a database of 342 images--74 positive (21.6%) and 268 negative (78.4%)-- belonging to 63 consecutive sera: 15 positive (23.8%) and 48 negative (76.2%). We assessed system performance by using k-fold cross-validation. Furthermore, we successfully validated the recognition system on 83 consecutive sera, collected by using different equipment in a referral center, counting 279 images: 92 positive (33.0%) and 187 negative (67.0%)., Results: With respect to well classification, the system correctly classified 98.4% of wells (62 out of 63). Integrating information from multiple images of the same wells recovers the possible misclassifications that occurred at the previous steps (cell and image classification). This system, validated in a clinical routine fashion, provides recognition accuracy equal to 100%., Conclusion: The data obtained show that automation is a viable alternative for Crithidia luciliae immunofluorescence test analysis.

The purpose of the present study was to determine levels of adipokines and their relationship with stiffness parameters and disease activity index in SLE patients in comparison with healthy controls. Sixty SLE patients and 29 control subjects were enrolled in the study. Serum leptin and adiponectin levels were determined by commercial sandwich ELISA kits. Colour-coded carotid duplex sonography was performed using a Siemens SONOLINE Antares machine equipped with linear 5-13 MHz. SLEDAI, ECLAM and SLICC were evaluated in all patients. Data were analysed by software for statistical analysis (Prism 5.0). Median leptin is higher among SLE patients compared with controls (p 0.035). Median values of vascular stiffness and PSEM are increased in SLE compared with controls (p = 0.0003 and p = 0.007). Vascular strain and vascular distensibility are lower in SLE patients in comparison with controls (p = 0.0001 and p = 0.0006, respectively). Considering SLE patients, leptin levels correlate with vascular stiffness (r = 0.64, p < 0.0001) and PSEM (r = 0.63, p < 0.0001). Adiponectin levels correlate with vascular strain (r = 0.28, p 0.039) and negatively correlate with vascular stiffness (r = -0.38, p 0.039). Leptin levels correlate with disease activity (SLEDAI and ECLAM) and cumulative damage (SLICC) indexes. This study demonstrates higher values of leptin in SLE patients. Moreover, SLE patients show increased levels of vascular stiffness and PSEM and reduced values of vascular strain and distensibility. These results globally indicate a decline in arterial elasticity. We find a positive correlation of leptin with stiffness parameters. According to its atheroprotective action, adiponectin inversely correlates with stiffness parameters.

The recommended method for antinuclear antibodies (ANA) detection is IIF but it is influenced by many different factors. In order to pursue a high image quality without artefacts and to reduce inter-observer variability, this study aims to evaluate the reliability of using automatically acquired digital images for diagnostic purposes. In this paper we present SLIM-system a comprehensive system that supports the two sides of IIF tests classification. It is based on two systems: the first labels the fluorescence intensity, whereas the second recognizes the staining pattern of positive wells. We populated a dataset of 600 images obtained from sera screened for ANA by IIF on Hep-2 cells. The error rate has been evaluated according to eight-fold cross validation method; the rates reported in the following are the mean of the tests. Performance of the system in positive/negative recognition ranges from 87% up to more than 94%. Staining pattern classification accuracy of main classes ranges from 71% to 74%. The system provides high and reliable identification of negative samples and a flexibility that permits to use this application for different purposes. The analysis of its perspective performance shows the system potential in lowering the method variability, in increasing the level of standardization and in reducing the specialist workload of more than 80%. Our data represent a first step to validate the use of Computer Aided Diagnosis (CAD), thus offering an opportunity for standardizing and automatizing the detection of ANA by IIF., (Copyright © 2011 Elsevier B.V.

Objectives: BAFF and APRIL belong to the tumor necrosis factor (TNF) superfamily and are crucial for the survival, maturation, and differentiation of B cells. Aim of the study is to evaluate BAFF and APRIL in patients affected by Sjögren syndrome (SS) and systemic lupus erythematosus (SLE)., Methods: Sixty patients, (40 SLE, 20 SS) and 20 healthy subjects were enrolled in this study. All subjects were evaluated for laboratory data (ESR, CRP, immunoglobulin G, A and M, complement fragments C3 and C4, LDH, beta2microglobulin, serum levels of rheumatoid factor), autoantibodies (ANA; ENA-SSA, -SSB, -Sm) and lymphocytes subpopulations. For patients, disease activity and damage indexes were assessed with the use of SLEDAI and SLICC and SSDAI and SSDDI for SLE and SS, respectively. BAFF and APRIL were determined by commercial sandwich ELISA kit (R&D Systems, Bender MedSystem). Statistical analysis has been performed with software Prism (Graphpad Instat, version 5.00)., Results: APRIL levels were higher among SLE and SS patients compared to controls (p<0.0001, and p0.0001, respectively). BAFF levels in SLE were significantly higher than in SS (p<0.0001). We found higher BAFF levels in SLE and SS compared to controls (p<0.0001). Among SLE patients APRIL correlated with SLEDAI (r 0.3, p 0.04), SLICC (r 0.5,p 0.001), ESR (r 0.3, p 0.005) and CRP (r 0.4, p 0.02). Among SS patients APRIL correlated with SSDAI (r 0.4, p 0.02), SSDDI (r 0.4, p0.01), IgG (r 0.5, p0.01), ESR (r 0.6, p 0.01), CRP (r 0.6, p 0.02) and CD19 B lymphocytes absolute count (r 0.4, p 0.04); BAFF correlated with SSDDI (r 0.7, p 0.004) and CD19 B lymphocytes absolute count (r 0.5, p 0.04)., Conclusions: In this study we showed a correlation between disease activity, damage indexes and BAFF/APRIL levels in SLE and SS patients suggesting a role in the strong activation of the immune system in patients with active disease.

Objective: Aim of this study was to evaluate the prevalence of alexithymia in patients affected by SLE or RA and to investigate the correlation between alexithymia and immunoendocrine parameters (PRL, hGH, IL-6 and TNF-alfa)., Methods: Twenty-five patients (12 and 13 affected by SLE and RA, respectively) were enrolled into the study. The Toronto Alexithymia Scale-20 (TAS-20) was administered. PRL, hGH, IL-6 and TNF-alfa levels were measured by commercially available ELISA kits., Results: Alexithymia prevalence (TAS-20 > or = 51) was 54% in RA and 42% in SLE patients. hGH serum levels were 3.1+/-4.2 and 1.1+/-0.9 IU/ml in SLE and RA, respectively. PRL concentration was 18.4+/-6.5 ng/ml and 14.2+/-4.0 ng/ml in SLE and RA patients, respectively (p=0.03). In RA group, TNF-alpha was 20+/-36.2 whereas in SLE it was 4.9+/-12.8 pg/ml (p=0.03); IL-6 serum concentrations were 24.4+/-25.1 and 2.9+/-5.4 pg/ml, in RA and SLE respectively (p=0.004). The serum level of hGH showed slight increase in alexithymic group (A) compared to non alexithymic group (NA) in both SLE and RA patients. PRL serum levels in SLE-A patients was 26.7+/-17.3 ng/ml while in SLE-NA patients was 12.4+/-3.3 ng/ml (p=0.04). In RA patients increased values of IL-6 and TNF-alpha were present in the A group compared to NA group (IL-6: 35.3+/-28 pg/mL vs 3.5+/-3.9 pg/mL, p=0.01; TNF-alpha: 34.7+/-39 pg/mL vs 3.1+/-3.4 pg/mL, p=0.01)., Conclusions: In this preliminary results we found an high prevalence of alexithymia and a correlation between immunoendocrine parameters and alexhytimic features in SLE and RA, suggesting that an immunomodulatory pathway could influence this cognitive style in patients with autoimmune disorders. Other studies should contribute to find a common biological pathway linking alexithymia and autoimmunity.

Neuropsychiatric involvement in patients with Systemic Lupus Erythematosus (SLE), first mentioned by Kaposi more than 100 years ago, still remains one of the main challenge facing rheumatologist and other physicians. The diagnosis of neuropsychiatric SLE (NPSLE) is complex not only because of the considerable prevalence variation (14-80%) but also because of the wide spectrum of NP manifestations. They vary from overt neurologic alterations (seizure, psychosis), to subtle abnormalities (neurocognitive dysfunctions). Different NP manifestations result from a variety of mechanisms including antibodies, vasculitis, thrombosis, hemorrhages and cytokine-mediated damages. Of note, despite the dramatic clinical manifestations, too often changes at the morphological neuroimaging techniques are minimal and non specific. There is no one diagnostic tool specific for NPSLE and diagnosis must be based on the combinated use of immunoserological tests, functional and anatomical neuroimaging and standardized specific criteria. Symptomatic, immunosuppressive and anticoagulant therapies are the main strategies available in the management of these patients. Therapy for CNS lupus should be adjusted according to the needs of the individual patients. The coming years promise to be an important time for the development of new neuroimaging techniques and for the study of disease mechanism. An early and objective identification of brain involvement will allow for appropriate treatment to avoid severe complications.
