Abstract
OBJECTIVE Lichen sclerosus is a chronic, inflammatory, progressive skin disease predominantly affecting anogenital areas. Vulvar lichen sclerosus (VLS) is one of the most common conditions treated in vulvar clinics; most patients report distressing symptoms of itching, burning, stinging, and pain (particularly during or after sexual intercourse). A preliminary, prospective, single-center study was performed to investigate the efficacy of hyaluronan hybrid cooperative complex (HCC) comprising high and low molecular weight hyaluronic acid to treat menopausal women with VLS. PATIENTS AND METHODS Patients (N = 30) received two HCC injections at 32 mg/ml (one month apart). At baseline and one and six months after treatment, patients completed validated psychometric questionnaires to assess their self-reported pain, itching, and dryness using the Visual Analogue Scale (VAS) and sexual function by the Female Sexual Function Index (FSFI). RESULTS After treatment with HCC, no side effects or complications were reported. VAS scores showed a trend towards reduced pain and itching intensity, and there was a statistically significant reduction in median VAS score for dryness at follow-up vs. baseline (p=0.038). For sexual function, there was a statistically significant improvement in lubrication (p=0.001) and orgasm (p=0.001) FSFI domains. CONCLUSIONS Overall, this preliminary study demonstrated the promising efficacy of HCC in menopausal women with VLS without side effects.

Abstract
BackgroundPsoriatic Arthritis (PsA) is a chronic inflammatory disease, characterized by both articular and periarticular manifestations, usually associated with psoriasis. The identification of the correct therapy for patients is still a critical issue, but the use of biological drugs, such as TNFi (Tumor Necrosis Factor Inhibitors), modified the outcome of PsA patients even if there is great variability in the clinical efficacy. Since the response to drugs is a complex trait, the identification of genetic factors could help to define new genomic biomarkers for more effective and personalized therapy.ObjectivesThe aim of this study was to evaluate the potential role of polymorphisms in genes already known to be involved in PsA susceptibility (ERAP1, HCP5, IL10, MIR146, PSORS1C1, STAT4, TNFAIP3 and TRAF3IP2) as predictors of efficacy of treatment, in a cohort of Italian PsA patients, treated with first-line TNF-i, in particular with Etanercept (ETN) and Adalimumab (ADA).MethodsPolymorphisms were analyzed in a cohort of 163 patients with peripheral PsA. For each patient was estimated the Disease Activity in Psoriatic Arthritis (DAPsA) score. Genotyping was performed by allelic discrimination by TaqMan assay. The possible association between the selected SNPs and mean values of DAPsA differences, at 22 (ΔT22) and 54 (ΔT54) weeks from the beginning of the TNF-i treatment, were evaluated by T-test. A multivariate logistic regression analysis was used to evaluate the contribution of each genetic variant investigated in the TNF-i treatment response.ResultsWe have observed that TRAF3IP2 SNP was associated with TNF-i treatment response in PsA patients. In particular, the patients carrying variant alleles seem to respond better to treatment, both at 22 (P = 0.032) and 54 weeks (P = 0.019). Moreover, the variant allele of TRAF3IP2 SNP resulted associated with a better response of joints involvement. Indeed, the number of tender and swollen joints decrease more in patients carrying variant allele (P = 0.006 and P = 0.024, respectively). We also observed that PsA patients carrying IL10 variant allele decrease their mean DAPsA value less than patients with wild-type genotype only at 54 weeks of treatment (P = 0.031). Also, HCP5 polymorphism showed a difference of mean difference of DAPsA values between genotypes for both follow up, even if these difference does not reach a statistical significance (P = 0.068 and P = 0.086). The multivariate regression analysis was performed with a stepwise method and it confirmed the involvement of TRAF3IP2 (P = 0.016) and HCP5 (P = 0.035) polymorphisms in the TNF-i response after 22 weeks and of TRAF3IP2 (P = 0.007), IL10 (P = 0.022) and HCP5 (P = 0.036) polymorphisms after 54 weeks. The two final models explain about 6% and 11% of the variability in TNF-i treatment response at 22 and 54 weeks respectively.ConclusionOur results suggest that some polymorphisms in genes associated to PsA susceptibility could also play a role in TNFi treatment response and could give a contribution in the definition of a genetic profile associated with the response to anti-TNF drugs.Figure 1.Mean differences of DAPsA values in the genotypic classes for TRAF3IP2, IL10 and HCP5 SNPs.

Abstract
OBJECTIVE Temporary COVID-19 hotels have been established in Italy to assist the homeless people that test positive for SARS-CoV-2 and require isolation. This observational study aimed to investigate the characteristics of the subjects who were isolated at the Casa tra Noi COVID-19 hotel in Rome between October 2020 and May 2021 and to estimate the duration of SARS-CoV-2 positivity according to their main socio-demographic, behavioural and clinical features. SUBJECTS AND METHODS Socio-demographic data, clinical history, and anamnestic data of guests were collected by the clinicians reviewing the medical documentation and face-to-face interviewing. Nasopharyngeal swabs were performed every 7 days and the presence of SARS-CoV-2 was assessed by RT-PCR. Median duration of SARS-CoV-2 positivity according to socio-demographic, behavioral factors and clinical condition was calculated. RESULTS The 196 guests (161 males, 82.1%) had a median age of 41 years (IQR: 30-53), and were mostly African (87, 44.4%). Only asymptomatic/paucisymptomatic infections were observed. Almost half of the individuals (84, 42.9%) were affected by at least one co-morbidity, the frequency of which was higher among women (57.1% vs. 39.8%, p=0.06). The date of the negative SARS-CoV-2 molecular test was known for 144 guests (73.5%). Among these, the median duration of positivity was 21 days (IQR: 14-26) and did not significantly vary with age, country of origin, smoking status, alcohol or drug abuse. Among the co-morbidities, only infectious diseases significantly modified the duration of positivity, which increased from 21 to 34 days (p=0.013). CONCLUSIONS Hotel guests were frequently affected by physical/mental co-morbidities. Duration of SARS-CoV-2 positivity was significantly prolonged only in individuals affected by an infectious disease.

Abstract
OBJECTIVES To evaluate the prevalence and therapeutic relevance of drug resistance among isolates from ART-experienced HIV-1-infected patients over the past two decades in Italy. METHODS Dynamics of resistance to one, two and three or more antiretroviral classes were evaluated from 1999-2018. Virological success (VS) after the latest therapy switch was evaluated according to cumulative class resistance and cumulative genotypic susceptibility score (Stanford HIV_DB algorithm). RESULTS Among 13 663 isolates (from 6739 patients), resistance to at least one drug class decreased sharply from 1999 to 2010 (≤2001, 84.6%; 2010, 43.6%; P < 0.001), then remained relatively constant at ∼40% during 2010-18, with the proportion of resistance to three or more classes also stable (∼5%). After 2008, integrase inhibitor resistance slightly increased from 5.6% to 9.7% in 2018 and contributed to resistance, particularly in isolates with resistance to three or more classes (one class, 8.4%; two classes, 15.3%; three or more classes, 34.7%, P < 0.001). Among 1827 failing patients with an available follow-up, by 1 year after genotype-guided therapy start the probability of VS was 87.6%. Patients with cumulative resistance to three or more classes and receiving a poorly active regimen showed the lowest probability (62.6%) of VS (P < 0.001) compared with all other patients (≥81.8%). By Cox regression analysis, cumulative MDR and receiving poorly active antiretroviral regimens were associated with a lower hazard of VS compared with those without resistance. CONCLUSIONS A dramatic drop of HIV-1 drug resistance at failure has been achieved over the last two decades in Italy; resistance to three or more classes is low but present among currently failing patients. Its management still requires a rational and careful diagnostic and therapeutic approach.

Abstract
Background The clinical manifestations of recent syphilis can be variable, with typical and atypical patterns. Several conditions may cause atypical clinical aspects, including human immunodeficiency virus (HIV) co-infection. Besides the clinical features, co-infections may completely alter syphilis serological tests, causing interpretative difficulties and diagnostic delays. Aim of the work is to describe the difficulties encountered during the diagnostic evaluation of atypical skin manifestations and of the serology for syphilis of an HIV-infected patient who had contracted it several times. Case presentation In 2020, a 52-year old HIV-positive bisexual male patient was admitted to our department with a 4-month history of moderately itchy cutaneous lesions localized at his neck, trunk and arms. In 2013, the patient presented with a classic syphilitic roseola of the trunk and a secondary syphilis was diagnosed, with increased levels of rapid plasma reagin (RPR), Treponema pallidum hemagglutination assay (TPHA), anti-Treponema pallidum IgM and IgG Index. A second episode occurred in 2018, as a primary syphilis with multiple ulcerative lesions of the penis, and increased levels of RPR, IgG and IgM. In 2019, a further episode of secondary syphilis was treated with Doxycycline. In 2020, erythematous and papular lesions with vesicular components and urticarial erythema multiforme (EM)-like lesions were present at the neck, trunk and arms. Serological tests and Nucleic Acid Amplification Test (NAAT) for Treponema Pallidum were performed, as well as a cutaneous biopsy with histological and immunohistochemical evaluation of one lesion. NAAT was negative for T. pallidum. Serological test results were discordant with a new syphilis infection, showing only increased levels of RPR and anti-Treponema IgG. The cutaneous biopsy revealed a non specific histological pattern, while the immunohistochemical evaluation with anti-spirochetal antibodies was mandatory for the diagnosis of recent syphilis, showing clusters of rod-shaped elements, some of which with spiral form, focally present at the epidermis and adnexal structures. Conclusions Nowadays, syphilis may present with atypical clinical and serological features. Physicians should be aware of these possible alterations and consider syphilis even in case of uncommon clinical aspect and unclear serological tests. Cutaneous biopsy and immunohistochemical exam may be mandatory for the diagnosis.

Abstract
Background:Psoriatic arthritis (PsA) is a chronic inflammatory joint disease typically associated with psoriasis and classified in the group of spondyloarthritis (1). The pathogenesis is based on an interplay of different genes interacting with several environmental factors including stress, trauma, infections, triggering an inflammatory response related to the activation of innate and acquired immunity in different tissues and organs (2). However, the risk for the development of PsA is not clearly understood.Objectives:The aim of this study was to evaluate, in a cohort of Italian PsA out-patients of the Rheumatology Unit of the University of Rome Tor Vergata, the association of genetic variants in candidate genes for PSA susceptibility and their possible contribute in the modulation of clinical and laboratory features.Methods:The genes were selected according to previous studies describing these genes as involved in susceptibility to rheumatoid arthritis (RA) (3), since a common genetic background can be shared between these diseases. Nine SNPs (single nucleotide polymorphism) in eight candidate genes were analysed: STAT4 (rs7574865), TRAF3IP2 (rs33980500), TNFAIP3 (rs6920220 and rs2230926), MIR146A (rs2910164), PSORS1C1 (rs2233945), IL-10 (rs1800872), HCP5 (rs3099844) and ERAP1 (rs27524). Polymorphisms were analysed in 163 consecutive PsA out-patients and 198 healthy controls (HC). Genotyping was performed by allelic discrimination by TaqMan assay. Alleles frequencies differences between cases and controls or between phenotypic groups were compared using Pearson’s χ 2 test.Results:We have observed an association between PSA susceptibility and the variant alleles of STAT4 [OR= 1.60 (1.15-2.21), P= 0.005], TRAF3IP2 [OR= 1.65 (1.01-2.65), P= 0.04], ERAP1 [OR= 1.40 (1.05-1.85), P= 0.02] and TNFAIP3 (rs6920220) [OR= 1.75 (1.19-2.57), P= 0.004]. On the contrary, the variant allele of IL-10 polymorphism seems to play a protective role [OR= 0.74 (1.05-1.85), P= 0.05]. Moreover, in order to define a genetic risk profile, we have counted the total number of risk alleles in each subject, considering as risk alleles the allelic variant of rs7574865 (STAT4), rs33980500 (TRAF3IP2), rs6920220 (TNFAIP3) and rs27524 (ERAP1) SNPs. Then, we have compared the risk allele number distribution between patients and HC (Fig.1). Classes with 3 or more risk alleles are significantly more represented in patients than in HC (OR= 2.03, P=0.004). The risk to develop the disease increases significantly in subjects with at least four risk alleles (OR= 2.96, P=0.002).Figure 1.Number of risk alleles in patients and controls: rs7574865 (STAT4), rs33980500 (TRAF3IP2), rs6920220 (TNFAIP3) and rs27524 (ERAP1) SNPs.Conclusion:We confirm the associations between five SNPs, already studied in RA, and PSA susceptibility, suggesting a common inflammatory pathway in chronic inflammatory rheumatological diseases. Moreover, we show how the genotyping of only few associated SNPs could help to define a genetic risk profile for PSA development.References:[1]Calabresi E, et al.

Abstract
Despite the high prevalence of diabetic neuropathy, its early start, and its impact on quality of life and mortality, unresolved clinical issues persist in the field regarding its screening implementation, the understanding of its mechanisms, and the search for valid biomarkers, as well as disease-modifying treatment. Genetics may address these needs by providing genetic biomarkers of susceptibility, giving insights into pathogenesis, and shedding light on how to select possible responders to treatment. After a brief summary of recent studies on the genetics of diabetic neuropathy, the current review focused mainly on microRNAs (miRNAs), including the authors' results in this field. It summarized the findings of animal and human studies that associate miRNAs with diabetic neuropathy and explored the possible pathogenetic meanings of these associations, in particular regarding miR-128a, miR-155a, and miR-499a, as well as their application for diabetic neuropathy screening. Moreover, from a genetic perspective, it examined new findings of polymorphisms of miRNA genes in diabetic neuropathy. It considered in more depth the pathogenetic implications for diabetic neuropathy of the polymorphism of MIR499A and the related changes in the downstream action of miR-499a, showing how epigenetic and genetic studies may provide insight into pathogenetic mechanisms like mitochondrial dysfunction. Finally, the concept and the data of genotype-phenotype association for polymorphism of miRNA genes were described. In conclusion, although at a very preliminary stage, the findings linking the genetics and epigenetics of miRNAs might contribute to the identification of exploratory risk biomarkers, a comprehensive definition of susceptibility to specific pathogenetic mechanisms, and the development of mechanism-based treatment of diabetic neuropathy, thus addressing the goals of genetic studies.

Abstract
BACKGROUND Lichen sclerosus is a chronic relapsing inflammatory dermatosis with a predilection for anogenital skin in 85%-98% of cases and is more prevalent in women (3%) than in men (> 0.07%). OBJECTIVES The purpose of this study was to investigate gender differences in clinical presentation and therapeutic response to treatment with platelet-rich plasma (PRP), an emerging innovative strategy for LS. METHODS Forty-three male and 51 female patients affected by LS were evaluated. Each patient was subjected to PRP treatment (1 infiltration every 15 days, for 3 times). RESULTS The PRP procedure was well tolerated by all patients and an overall significant decrease in symptoms was reported 6 months after PRP infiltration. Reduction in pain and burning sensation was significant in both gender but more accentuated in women than in men, whereas reduction of itching was similar. On the contrary, dyspareunia evidenced sex-related difference since a significant diminution was observed only in male. CONCLUSIONS This study demonstrates that PRP based therapy may exert a relevant role in LS patient management due to its effect on Quality of Life (QoL) and sexual function in both gender. In addition, the study underlined gender-related differences in severity of symptoms and disease age onset.

Abstract
The host evolves redundant mechanisms to preserve physiological processing and homeostasis. These functions range from sensing internal and external threats, creating a memory of the insult and generating reflexes, which aim to resolve inflammation. Impairment in such functioning leads to chronic inflammatory diseases. By interacting through a common language of ligands and receptors, the immune and sensory nervous systems work in concert to accomplish such protective functions. Whilst this bidirectional communication helps to protect from danger, it can contribute to disease pathophysiology. Thus, the somatosensory nervous system is anatomically positioned within primary and secondary lymphoid tissues and mucosa to modulate immunity directly. Upstream of this interplay, neurons detect danger, which prompts the release of neuropeptides initiating (i) defensive reflexes (ranging from withdrawal response to coughing) and (ii) chemotaxis, adhesion and local infiltration of immune cells. The resulting outcome of such neuro-immune interplay is still ill-defined, but consensual findings start to emerge and support neuropeptides not only as blockers of TH 1-mediated immunity but also as drivers of TH 2 immune responses. However, the modalities detected by nociceptors revealed broader than mechanical pressure and temperature sensing and include signals as various as cytokines and pathogens to immunoglobulins and even microRNAs. Along these lines, we aggregated various dorsal root ganglion sensory neuron expression profiling datasets supporting such wide-ranging sensing capabilities to help identifying new danger detection modalities of these cells. Thus, revealing unexpected aspects of nociceptor neuron biology might prompt the identification of novel drivers of immunity, means to resolve inflammation and strategies to safeguard homeostasis.

Abstract
OBJECTIVES The aim of the study was to compare the efficacy and tolerability of switching antiretroviral therapy to dolutegravir + emtricitabine/tenofovir disoproxil fumarate (TDF) with those of switching to elvitegravir/cobicistat/emtricitabine/TDF in clinical practice. METHODS In a multicentre real-life observational study, we analysed data for HIV-infected patients on antiretroviral treatment with viral load < 50 HIV-1 RNA copies/mL switching to dolutegravir + emtricitabine/TDF (dolutegravir group) or elvitegravir/cobicistat/emtricitabine/TDF (elvitegravir group). Follow-up was censored at 48 weeks. RESULTS The 48-week estimated proportion maintaining virological efficacy was 96.1% with dolutegravir (n = 123) and 95.4% with elvitegravir (n = 186; P = 0.941). Patients in the dolutegravir group showed more treatment discontinuations, but these were mainly as a result of simplification. The elvitegravir group showed more discontinuations because of renal adverse events (2.7% versus 0% with dolutegravir). Interestingly, no difference was observed between the two regimens in central nervous system toxicity-related discontinuations. Switching to dolutegravir was associated with a better blood lipid profile. CONCLUSIONS Switching to dolutegravir + emtricitabine/TDF was associated with similar efficacy and tolerability to switching to elvitegravir/cobicistat/emtricitabine/TDF in virologically suppressed patients in clinical practice, although reasons for discontinuation showed differences between regimens. These results should be interpreted with caution, as this is a nonrandomized comparison.

Abstract
Systemic lupus erythematosus (SLE) is a common heterogeneous autoimmune disease that is caused by the involvement both of genetic and environmental factors. There is evidence that autophagy is involved in several aspects of SLE pathogenesis. In particular, polymorphisms in the ATG5 gene have been observed to be associated with disease susceptibility. Our aim was to verify if ATG5 polymorphisms are involved in the susceptibility to disease and its clinical phenotypes in an Italian cohort of SLE patients. This study involved 315 SLE patients and 265 healthy controls. Three polymorphisms in the ATG5 gene (rs573775, rs6568431 and rs2245214) were investigated by allelic discrimination assay. A case-control association study, a genotype/phenotype correlation analysis and a haplotype study were performed. Moreover, an expression study was conducted in peripheral blood mononuclear cells from 15 SLE patients to verify a possible effect of the three SNPs on the expression of ATG5. Among the three investigated SNPs, only the rs573775 SNP was significantly associated with disease susceptibility with the variant allele conferring a higher risk of developing SLE (OR = 1.50, p = 0.018 and OR = 1.48, p = 0.007 at the genotypic and allelic level, respectively). The variant allele of rs6568431 SNP was more present in patients with anemia (OR = 1.86, p = 0.009) and renal involvement (OR = 1.63, p = 0.06), while the variant allele of rs2245214 SNP was significantly associated with a higher risk of producing anti-DNA autoantibodies (OR = 1.66, p = 0.04). Carriers of the rs6568431 variant allele showed higher messenger RNA levels compared to the carriers of the wild-type allele, suggesting also a potential variant allele dose-dependent effect on gene expression. In conclusion, our study confirms a role for ATG5 polymorphisms both in disease susceptibility and in the modulation of clinical phenotypes in an Italian SLE cohort. These results further suggest that genetic variations in autophagy genes could play a role in autoimmune diseases susceptibility and are worth further investigation.

Abstract
OBJECTIVES We evaluated the efficacy and tolerability of lamivudine + dolutegravir in a cohort of HIV-1 infected, treatment-experienced patients with undetectable HIV-RNA. METHODS Time to treatment discontinuation (TD) and virological failure (VF) and their predictors were assessed in a multicenter cohort of HIV-1 infected patients, starting lamivudine + dolutegravir after reaching viral suppression. Secondary objective was the evaluation of changes in lipid profile, renal and immunological functions at week 48. RESULTS We enrolled 206 patients (72.8% male, with 51 years median age), who mainly switched their antiretroviral therapy for simplification (32.5%) or drug toxicity (54.5%). The estimated probability of maintaining virological suppression at 48 and 96 weeks was 98.2% and 95.1%, respectively. VF was independently predicted by cumulative time on antiretroviral therapy. The estimated probability of remaining on lamivudine plus dolutegravir was 86.7% and 80.5% at week 48 and 96, respectively. A significant improvement in immunological function (CD4 count and CD4/CD8 ratio) was evidenced at week 48, as well as a decrease in total cholesterol/HDL ratio, triglycerides and estimated glomerular filtration rate. CONCLUSIONS Lamivudine plus dolutegravir was effective in maintaining viral suppression in our cohort and led to an improvement in metabolic and immunologic functions.

Abstract
In the present study, the Pulsed Laser Deposition (PLD) technique was applied to coat titanium for orthopaedic and dental implant applications. Calcium carbonate (CC) was used as starting coating material. The deposited CC films were transformed into octacalcium phosphate (OCP) by chemical treatments. The results of X-ray diffraction (XRD), Raman, Fourier Transform Infrared Spectroscopy (FTIR) and scanning electron microscopy (SEM) studies revealed that the final OCP thin films are formed on the titanium surface. Human myofibroblasts from peripheral vessels and the primary bone marrow mesenchymal stromal cells (BMMSs) were cultured on the investigated materials. It was shown that all the investigated samples had no short-term toxic effects on cells. The rate of division of myofibroblast cells growing on the surface and saturated BMMSs concentration for the OCP coating were about two times faster than of cells growing on the CC films.

Abstract
Recently, a study has shown that a polymorphism in the region of MIR1279 modulates the expression of the TRAF3IP2 gene. Since polymorphisms in the TRAF3IP2 gene have been described in association with systemic lupus erithematosus (SLE) susceptibility and with the development of pericarditis, our aim is to verify if the MIR1279 gene variability could also be involved. The rs1463335 SNP, located upstream MIR1279 gene, was analyzed by allelic discrimination assay in 315 Italian SLE patients and 201 healthy controls. Moreover, the MIR1279 gene was full sequenced in 50 patients. A case/control association study and a genotype/phenotype correlation analysis were performed. We also constructed a pericarditis genetic risk profile for patients with SLE. The full sequencing of the MIR1279 gene in patients with SLE did not reveal any novel or known variation. The variant allele of the rs1463335 SNP was significantly associated with susceptibility to pericarditis ( P = 0.017 and OR = 1.67). A risk profile model for pericarditis considering the risk alleles of MIR1279 and three other genes (STAT4, PTPN2 and TRAF3IP2) showed that patients with 4 or 5 risk alleles have a higher risk of developing pericarditis ( OR = 4.09 with P = 0.001 and OR = 6.04 with P = 0.04 respectively). In conclusion, we describe for the first time the contribution of a MIR1279 SNP in pericarditis development in patients with SLE and a genetic risk profile model that could be useful to identify patients more susceptible to developing pericarditis in SLE. This approach could help to improve the prediction and the management of this complication.

Abstract
OBJECTIVES Despite not being approved in Europe as first-line therapy, the efavirenz (EFV)-containing single tablet regimen (STR) is frequently used in clinical practice in naïve patients but few data are available on this strategy. In our study, we aimed to assess the risk of EFV discontinuation in patients starting antiretroviral therapy with STR vs. nonSTR. METHODS This was a multicentre study retrospectively enrolling naïve patients starting EFV+TDF+FTC. Patients were followed from the time of treatment initiation to the discontinuation of the EFV-containing regimen, comparing STR vs. nonSTR. Two different analyses were performed: (A) nonSTR patients censored at the last observation (switch to STR not considered as the end of observation); (B) nonSTR patients censored at the time of switch to STR. RESULTS The study included 235 patients, of whom 74 (31.5%) directly started STR. Among patients starting nonSTR, 108 (67.1%) switched to STR after a median period of 6 months. Forty-four EFV discontinuations were observed (13 among STR vs. 31 among nonSTR patients). The overall estimated probability of discontinuation was 30% at 5 years, about half (14.8%) of these occurring during the first year. Analysis A did not show significant differences between STR and nonSTR regarding the probability of efavirenz discontinuation (19.9% vs. 24.7% at 5 years, P = 0.630). In contrast, Analysis B showed that the probability of EFV discontinuation was similar (8.3%) between STR and nonSTR patients up to 8 months. Thereafter, a significantly higher rate of discontinuation was observed in nonSTR patients (47.5% vs. 19.9% at 5 years, P = 0.034). CONCLUSIONS Our data suggest that an early switch to STR during the first months of treatment could reduce the risk of EFV discontinuation.

Abstract
OBJECTIVES Integrase drug resistance monitoring deserves attention because of the increasing number of patients being treated with integrase strand-transfer inhibitors. Therefore, we evaluated the integrase genotyping success rate at low-level viraemia (LLV, 51-1000 copies/mL) and resistance in raltegravir-failing patients. METHODS An integrase genotypic resistance test (GRT) was performed on 1734 HIV-1 samples collected during 2006-13. Genotyping success rate was determined according to the following viraemia levels: 51-500, 501-1000, 1001-10 000, 10 001-100 000 and >100 000 copies/mL. The reproducibility of integrase GRT was evaluated in 41 plasma samples processed in duplicate in two reference centres. The relationship between LLV and resistance prevalence was evaluated in a subset of 120 raltegravir-failing patients. RESULTS Overall, the integrase genotyping success rate was 95.7%. For viraemia levels 51-500 and 501-1000 copies/mL, the rate of success was 82.1% and 94.0%, respectively. GRT was reproducible, producing sequences with a high similarity and an equal resistance profile regardless of the sequencing centre or viraemia level. Resistance was detected both at LLV and at viraemia >1000 copies/mL (51-500 copies/mL = 18.2%; 501-1000 = 37.5%; 1001-10 000 = 53.7%; 10 001-100 000 = 30.0%; and >100 000 = 30.8%). At viraemia ≤500 copies/mL, Q148H/K/R and N155H had the same prevalence (9.1%), while the Y143C/H/R was completely absent. At early genotyping (within 3 months of raltegravir treatment), Q148H/K/R and N155H mutations were detected regardless of the viraemia level, while Y143C/H/R was observed only in samples with viraemia >1000 copies/mL. CONCLUSIONS Our findings prove the reliability of HIV-1 integrase genotyping and reinforce the concept that this assay may be useful in the management of failures even at LLV.

Abstract
To assess trends in HIV-1 incidence and risk factors for seroconversion among men who have sex with men (MSM) resident in Rome, Italy, a retrospective longitudinal cohort study was conducted over 25 years. Incidence rates and trends were modelled using Poisson regression and risk factors were assessed by multivariate Cox models. Of 1,862 HIV-1-negative individuals, 347 seroconverted during follow-up. HIV-1 incidence rates increased from 5.2/100 persons/year (p/y) in 1986 (95% confidence interval (CI): 2.3–11.5) to 9.2/00 p/y in 1992 (95% CI: 6.4–13.0), decreased to 1.3/100 p/y in 2001 and increased until 2009 (11.7/100 p/y; 95% CI: 7.4–18.6). The risk of HIV-1 seroconversion increased during the study period in younger MSM (incidence rate ratio (IRR) = 17.18; 95% CI: 9.74–30.32 in 16–32 year-olds and IRR = 5.09; 95% CI: 2.92–8.87 in 33–41 year-olds) and in those who acquired syphilis (IRR = 7.71; 95% CI: 5.00–11.88). In contrast, the risk of seroconversion decreased among highly educated MSM (IRR = 0.54; 95% CI: 0.35–0.82) and those without Italian citizenship (IRR = 0.45; 95% CI: 0.28–0.71). The HIV epidemic in MSM living in Rome continues to expand. Targeted prevention programmes against sexually transmitted infections to enhance knowledge transfer and behavioural skills are urgently required.

Abstract
PURPOSE Cystic-fibrosis-associated liver disease (CFLD) may lead to portal hypertension (PHT) and cirrhosis. Clinical signs and biochemistry of liver involvement are not discriminating. The aim of the study was to evaluate the performance of acoustic radiation force impulse (ARFI) with virtual tissue quantification in comparison with clinical signs, biochemistry and standard hepatic ultrasound (US) patterns. MATERIALS AND METHODS Virtual Touch Tissue Quantification, an implementation of US ARFI with shear-wave velocity (SWV) measurements was used in 75 children with cystic fibrosis (CF) and suspected CFLD to quantify hepatic stiffness. In each patient, ten measurements of SWV were performed on the right hepatic lobe. Patients were also evaluated by standard diagnostic tools (standard US, liver- and lung function tests, oesophagogastroscopy). RESULTS Among CF patients, median SWV was significantly higher in patients with clinical, biochemical and US signs of hepatic involvement than in patients without US evidence of liver disease 1.08 m/s [(95% confidence interval (CI), 1.02-1.14]. Median SWV values in patients with portal hypertension, splenomegaly and oesophageal varices were 1.30 (95% CI, 1.17-1.43), 1.54 (95% CI, 1.32-1.75) and 1.63 (95% CI, 1.26-1.99), respectively. Differences were significant (p<0.001). CONCLUSIONS ARFI is an innovative screening technique able to help identify CFLD in children.

Abstract
Convergent epidemiological, clinical, and experimental findings indicate that hypercholesterolemia contributes to the onset of Alzheimer's disease (AD)-like dementia, but the exact underlying mechanisms remains unknown. In this study, we evaluated the cognitive performance of mice submitted to a model of hypercholesterolemia, as well as its relationship with mitochondrial dysfunction and oxidative stress, two key events involved in AD pathogenesis. Wild-type C57bl/6 or low density lipoprotein receptor (LDLr)-deficient mice were fed with either standard or cholesterol-enriched diet for a 4-week period and tested for spatial learning and memory in the object location task. LDLr⁻/⁻ mice displayed spatial learning and memory impairments regardless of diet. Moreover, LDLr⁻/⁻ mice fed cholesterol-enriched diet presented a significant decrease in the mitochondrial complexes I and II activities in the cerebral cortex, which were negatively correlated with respective blood cholesterol levels. Additionally, hypercholesterolemic LDLr⁻/⁻ mice presented a significant decrease in glutathione levels, about 40% increase in the thiobarbituric acid-reactive substances levels, as well as an imbalance between the peroxide-removing-related enzymes glutathione peroxidase/glutathione reductase activities in the cerebral cortex. These findings indicate a significant relationship between hypercholesterolemia, cognitive impairment, and cortico-cerebral mitochondrial dysfunctional/oxidative stress. Because of the involvement of such alterations in AD patients, our data render this mouse model of hypercholesterolemia a useful approach to comprehend the molecular events mediating AD pathogenesis.

Abstract
Patients suffering from depression frequently display hyperactivity of the hypothalamic-pituitary-adrenal axis (HPA) resulting in elevated cortisol levels. One main symptom of this condition is anhedonia. There is evidence that exercise training can be used as a rehabilitative intervention in the treatment of depressive disorders. In this scenario, the aim of the present study was to assess the effect of an aerobic exercise training protocol on the depressive-like behavior, anhedonia, induced by repeated dexamethasone administration. The study was carried out on adult male Wistar rats randomly divided into four groups: the "control group" (C), "exercise group" (E), "dexamethasone group" (D) and the "dexamethasone plus exercise group" (DE). The exercise training consisted of swimming (1 h/d, 5 d/wk) for 3 weeks, with an overload of 5% of the rat body weight. Every day rats were injected with either dexamethasone (D/DE) or saline solution (C/E). Proper positive controls, using fluoxetine, were run in parallel. Decreased blood corticosterone levels, reduced adrenal cholesterol synthesis and adrenal weight (HPA disruption), reduced preference for sucrose consumption and increased immobility time (depressive-like behavior), marked hippocampal DNA oxidation, increased IL-10 and total brain-derived neurotrophic factor (BDNF; pro-plus mature-forms) and a severe loss of body mass characterized the dexamethasone-treated animals. Besides increasing testosterone blood concentrations, the swim training protected depressive rats from the anhedonic state, following the same profile as fluoxetine, and also from the dexamethasone-induced impaired neurochemistry. The data indicate that physical exercise could be a useful tool in preventing and treating depressive disorders.

Abstract
The early diagnosis and treatment of individuals harboring M. tuberculosis is key to ensuring the effectiveness of health programs aimed at the elimination of tuberculosis (TB). Monitoring for TB also has other important health care implications for the related immune pathology caused by the chronic inflammatory response to M. tuberculosis. Moreover, the recent introduction of biologic therapies for the treatment of several immune-mediated inflammatory diseases has shown unexpected high frequencies of reactivation of latent TB. The present cross-sectional study is aimed at estimating the prevalence of latent tuberculosis infection (LTBI) in different groups of subjects, either undergoing a routine program of screening for TB or a clinical monitoring of autoimmune or lung disorders, by analyzing their immune response in vitro to a pool of different M. tuberculosis antigens through an IFN-gamma-release assay (IGRA). We consecutively tested 1,644 subjects including health care workers (931), healthy immigrants from different countries (93), patients with a diagnosis of psoriasis (405), patients with lung inflammatory disease (60) or lung neoplasia (32) and a group of HIV-1 infected Italian subjects (120). The prevalence of IGRAs positive responses among health care workers was 8.9 percent. In comparison, significantly higher frequencies were found in healthy immigrant subjects (33.3%), similar to those found in inflammatory broncho-pneumopathies (34.5%) or lung cancer (29.6%). Interestingly, an unexpected high prevalence was also found in patients affected by psoriasis (18.0%), while HIV-infected subjects had values comparable to those of health care workers (10.8%). An age cut-off was determined and applied for each group by receiver operating characteristic (ROC) curves in order to perform the statistical analysis among age-comparable groups. Multivariate analysis showed that the age and clinical conditions such as having a diagnosis of psoriasis or a lung inflammatory disease were independent risk factors for developing an IGRA positive response. This study highlights an unprecedented high prevalence of IGRA positive responses among patients affected by psoriasis and emphasizes the need for a preliminary assessment of LTBI before the administration of any biologic therapy based on cytokine antagonists such as anti-TNF-alpha. Moreover, screening for LTBI should be routinely performed in the presence of a chronic pulmonary disease.

Abstract
OBJECTIVE To determine glutamate and aspartate levels in the cerebrospinal fluid (CSF) in patients with sporadic amyotrophic lateral sclerosis (SALS) grouped according to El Escorial diagnostic criteria, and to perform an in vitro assessment of the neurotoxicity of the CSF in murine cortical neurons. METHODS SALS patients were sorted according to El Escorial diagnostic criteria. Glutamate and aspartate were measured in the CSF using high performance liquid chromatography. Cultured cortical neuron viability was determined after exposure to CSF for 24 h. RESULTS Glutamate levels were elevated in 28 out of the 29 patients with definite, probable or possible SALS. There were no differences in glutamate concentrations when the three clinical forms of the disease were compared; neither there were significant variation across disease duration and clinical presentation. In agreement with previous reports, we concluded that CSF-SALS-induced in vitro neurotoxicity is mediated by ionotropic glutamate receptors. We found no relationship between the degree of in vitro neurotoxicity and glutamate concentration in the CSF. CONCLUSIONS Glutamate but not aspartate CSF levels may contribute to ALS pathogenesis. However, glutamate levels may not influence the degree of diagnosis certainty or lesion extension.

Abstract
An increase in the circulation of HIV-1 non-B subtypes has been observed in recent years in Western European countries. Due to the lack of data on the circulation of HIV-1 non-B subtypes among European HIV-1-infected men who have sex with men (MSM), a biomolecular study was conducted in Rome, Italy. HIV-1 partial pol gene sequences from 111 MSM individuals (76 drug naive and 35 drug experienced) were collected during the years 2004-2006. All these sequences were analyzed using the REGA HIV-1 Subtyping Tool, and aligned using CLUSTAL X followed by manual editing using the Bioedit software. A BLAST search for non-B subtype sequences was also performed. Twenty-six (23.4%) MSM were not Italians. Eight individuals (7.2%) were diagnosed as HIV infected before 1991, 20 (18.0%) between 1991 and 1999, and 83 (74.8%) from 2000 to 2006. Fifteen (15/111, 13.5%) individuals were infected with the non-B subtype. The percentage of infection with HIV-1 non-B subtypes was 8.2% (7/85) among Italian MSM and 30.8% (8/26) among the non-Italians (OR = 4.95 95% IC: 1.40-17.87). Individuals infected with the non-B subtype were significantly younger than those infected with the HIV-1 B subtype (28 years vs. 34 years, p = 0.003). The CRFs were more prevalent (8.1%) than pure subtypes (5.4%), which were distributed as follows: subtype C (2.6%), subtype A1 (1.7%), and subtype F1 (0.9%). Major mutations conferring resistance to antiretroviral drugs (ARV) were not found among HIV-1 non-B subtype drug-naive patients but were found in two ARV-experienced individuals. The data show that viral diversity is likely increasing in a population group that had been previously characterized by the circulation of HIV-1 subtype B.

Abstract
Animal models of inborn errors of metabolism are useful for investigating the pathogenesis associated with the corresponding human disease. Since the mechanisms involved in the pathophysiology of succinate semialdehyde dehydrogenase (SSADH) deficiency (Aldh5a1; OMIM 271980) are still not established, in the present study we evaluated the tissue antioxidant defences and lipid peroxidation in various cerebral structures (cortex, cerebellum, thalamus and hippocampus) and in the liver of SSADH-deficient mice. The parameters analysed were total radical-trapping antioxidant potential (TRAP) and glutathione (GSH) levels, the activities of the antioxidant enzymes superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx), as well as thiobarbituric acid-reactive substances (TBARS). We first observed that the tissue nonenzymatic antioxidant defences were significantly reduced in the SSADH-deficient animals, particularly in the liver (decreased TRAP and GSH) and in the cerebral cortex (decreased GSH), as compared to the wild-type mice. Furthermore, SOD activity was significantly increased in the liver and cerebellum, whereas the activity of CAT was significantly higher in the thalamus. In contrast, GPx activity was significantly diminished in the hippocampus. Finally, we observed that lipid peroxidation (TBARS levels) was markedly increased in the liver and cerebral cortex, reflecting a high lipid oxidative damage in these tissues. Our data showing an imbalance between tissue antioxidant defences and oxidative attack strongly indicate that oxidative stress is involved in the pathophysiology of SSADH deficiency in mice, and likely the corresponding human disorder.

Abstract
We have previously demonstrated that octanoic (OA) and decanoic acids (DA) inhibit Na+, K+ ATPase activity in synaptic plasma membranes from rat brain. The objective of the present study was to investigate the in vitro effects of the other metabolites that accumulate in tissues of medium-chain acyl-CoA dehydrogenase (MCAD)-deficient patients, namely cis-4-decenoic acid (cDA), octanoylcarnitine (OC), hexanoylcarnitine (HC), hexanoylglycine (HG), phenylpropionylglycine (PPG) and suberoylglycine (SG), on Na+, K+ ATPase activity in synaptic plasma membrane from cerebral cortex of 30-day-old rats. cDA, the pathognomonic compound found in this disorder, provoked the strongest inhibition on this enzyme activity at concentrations as low as 0.25 mM, whereas OC inhibited this activity at 1.0 mM and higher concentrations in a dose-dependent manner. In contrast, HC, HG, PPG and SG did not affect Na+, K+ ATPase activity. Furthermore, pre-treatment of cortical homogenates with the antioxidant enzymes catalase plus superoxide dismutase totally prevented cDA-induced Na+, K+ ATPase inhibition. We also provided evidence that cDA, as well as OA and DA, caused lipid peroxidation, which may explain, at least in part, the inhibitory properties of these compounds towards Na+, K+ ATPase. Considering that Na+, K+ ATPase is a critical enzyme for normal brain development and functioning, it is presumed that these findings, especially those regarding to the marked inhibitory effect of cDA, may be involved in the pathophysiology of the neurological dysfunction of MCAD-deficient patients.

Abstract
There is an ever-growing interest in plant molecular farming as a system for producing valuable recombinant pharmaceutical molecules, such as single-chain variable fragments, on an industrial/agricultural scale and it appears that it is going to become a reality. Human epidermal growth factor receptor-2 (HER2) is an oncogene involved in abnormal cell growth in breast cancer and is considered for the development of new cancer therapies. We describe here the cloning and expression of a scFv-alpha HER2 that has been produced in Escherichia coli and in plants using both stable and transient systems in tobacco and Nicotiana benthamiana. Single-chain antibodies (ScFvs) extracted and purified from E. coli and plant tissues were tested for functionality and specificity by flow cytometry analysis on several cell lines and showed positive results when used on breast cancer slides coming from human frozen tissues. As a result, scFv-alpha HER2 represents a good opportunity for application and use in diagnosis and therapy.

Abstract
The pathophysiology of the striatum degeneration characteristic of patients affected by the inherited neurometabolic disorder glutaryl-CoA dehydrogenase deficiency (GDD), also known as glutaric aciduria type I, is still in debate. We have previously reported that 3-hydroxyglutaric acid (3-OH-GA) considered the main neurotoxin in this disorder, induces oxidative stress in rat cerebral cotex. In the present work, we extended these studies by investigating the in vitro effect of 3-OH-GA, at concentrations ranging from 0.01 to 1.0 mmol/L on the brain antioxidant defences by measuring total radical-trapping antioxidant potential (TRAP), total antioxidant reactivity (TAR) and glutathione (GSH) levels, and on the production of hydrogen peroxide (H(2)O(2)), nitric oxide (NO) and malondialdehyde in striatum homogenates from young rats. We observed that TRAP, TAR and GSH levels were markedly reduced (by up to 50%) when striatum homogenates were treated with 3-OH-GA. In contrast, H(2)O(2) (up to 44%), NO (up to 95%) and malondialdehyde levels (up to 28%) were significantly increased by 3-OH-GA. These data indicate that total nonenzymatic antioxidant defences (TRAP) and the tissue capacity to handle an increase of reactive species (TAR) were reduced by 3-OH-GA in the striatum. Furthermore, the results also reflect an increase of lipid peroxidation, probably secondary to 3-OH-GA-induced free radical production. Thus, it may be presumed that oxidative stress is involved in the neuropathology in GDD.

Abstract
Mitochondrial beta-ketothiolase and 2-methyl-3-hydroxybutyryl-CoA dehydrogenase (MHBD) deficiencies are inherited neurometabolic disorders affecting isoleucine catabolism. Biochemically, beta-ketothiolase deficiency is characterized by intermittent ketoacidosis and urinary excretion of 2-methyl-acetoacetate (MAA), 2-methyl-3-hydroxybutyrate (MHB) and tiglylglycine (TG), whereas in MHBD deficiency only MHB and tiglylglycine accumulate. Lactic acid accumulation and excretion are also observed in these patients, being more pronounced in MHBD-deficient individuals, particularly during acute episodes of decompensation. Patients affected by MHBD deficiency usually manifest severe mental retardation and convulsions, whereas beta-ketothiolase-deficient patients present encephalopathic crises characterized by metabolic acidosis, vomiting and coma. Considering that the pathophysiological mechanisms responsible for the neurological alterations of these disorders are unknown and that lactic acidosis suggests an impairment of energy production, the objective of the present work was to investigate the in vitro effect of MAA and MHB, at concentrations varying from 0.01 to 1.0 mmol/L, on several parameters of energy metabolism in cerebral cortex from young rats. We observed that MAA markedly inhibited CO2 production from glucose, acetate and citrate at concentrations as low as 0.01 mmol/L. In addition, the activities of the respiratory chain complex II and succinate dehydrogenase were mildly inhibited by MAA. MHB, at 0.01 mmol/L and higher concentrations, strongly inhibited CO2 production from all tested substrates, as well as the respiratory chain complex IV activity. The other activities of the respiratory chain were not affected by these metabolites. The data indicate a marked blockage in the Krebs cycle and a mild inhibition of the respiratory chain caused by MAA and MHB. Furthermore, MHB inhibited total and mitochondrial creatine kinase activities, which was prevented by the use of the nitric-oxide synthase inhibitor L-NAME and glutathione (GSH). These data indicate that the effect of MHB on creatine kinase was probably mediated by oxidation or other modification of essential thiol groups of the enzyme by nitric oxide and other by-products derived from this organic acid. In contrast, MAA did not affect creatine kinase activity. Taken together, these observations indicate that aerobic energy metabolism is inhibited by MAA and to a greater extent by MHB, a fact that may be related to lactic acidaemia occurring in patients affected by MHBD and beta-ketothiolase deficiencies. If the in vitro effects detected in the present study also occur in vivo, it is tempting to speculate that they may contribute, at least in part, to the neurological dysfunction found in these disorders.

Abstract
3-Hydroxyglutaric acid (3HGA) accumulates in the inherited neurometabolic disorder known as glutaryl-CoA dehydrogenase deficiency. The disease is clinically characterized by severe neurological symptoms, frontotemporal atrophy and striatum degeneration. Because of the pathophysiology of the brain damage in glutaryl-CoA dehydrogenase deficiency is not completed clear, we investigated the in vitro effect of 3HGA (0.01-5.0mM) on critical enzyme activities of energy metabolism, including the respiratory chain complexes I-V, creatine kinase isoforms and Na(+),K(+)-ATPase in cerebral cortex and striatum from 30-day-old rats. Complex II activity was also studied in rat C6-glioma cells exposed to 3HGA. The effect of 3HGA was further investigated on the rate of oxygen consumption in mitochondria from rat cerebrum. We observed that 1.0mM 3HGA significantly inhibited complex II in cerebral cortex and C6 cells but not the other activities of the respiratory chain complexes. Creatine kinase isoforms and Na(+),K(+)-ATPase were also not affected by the acid. Furthermore, no inhibition of complex II activity occurred when mitochondrial preparations from cerebral cortex or striatum homogenates were used. In addition, 3HGA significantly lowered the respiratory control ratio in the presence of glutamate/malate and succinate under stressful conditions or when mitochondria were permeabilized with digitonin. Since 3HGA stimulated oxygen consumption in state IV and compromised ATP formation, it can be presumed that this organic acid might act as an endogenous uncoupler of mitochondria respiration. Finally, we observed that 3HGA changed C6 cell morphology from a round flat to a spindle-differentiated shape, but did not alter cell viability neither induced apoptosis. The data provide evidence that 3HGA provokes a moderate impairment of brain energy metabolism and do not support the view that 3HGA-induced energy failure would solely explain the characteristic brain degeneration observed in glutaryl-CoA dehydrogenase deficiency patients.

Abstract
OBJECTIVE We have developed a standardized technique for intra-articular injection of the hip joint with the purpose of extending routine intra-articular injection of hyaluronans and steroids to the hip, as commonly used in the knee. The purpose of this study was to examine the safety of this technique in an extended series of patients. METHODS A 7 MHz linear or 3.5 MHz convex transducer was used with a sterilized biopsy guide attached. Intra-articular (IA) injection was performed by inserting into the biopsy guide a 20 gauge needle with the anterosuperior approach. Then, using biopsy real-time guidance software, the needle was advanced into the anterior capsular recess, at the level of the femoral head. RESULTS The standardised technique was used to inject 97 patients (114 hips) with 185 injections of either steroid/local anaesthetic (10) or hyaluronan (175) over a three-year period. The treatment was well tolerated with few, and exclusively local, side effects. No systemic side effects or joint infections were observed in our study. The colour Doppler vision allowed us to avoid injecting blood vessels. In all cases direct visualization of needle introduction and progression into the articular space was shown by on-screen guidance. Ultrasound guidance is more economic and faster in comparison to the TC or fluoroscopic guidance. Contrary to TC or fluoroscopic techniques ultrasound does not require use of radiations or iodized contrast. CONCLUSION Our data suggest that the administration of hyaluronans or steroids with ultrasound-guided intra-articular injection is a safe technique for treatment of rheumatic diseases of the hip.

Abstract
The diagnosis of autoimmune bullous diseases is based on clinical observation and on the presence of autoantibodies directed to molecules involved in the adhesion systems of the skin. Immunofluorescence assays are the currently accepted method for detection of autoantibodies; such assays depend greatly on the skill of operators and are difficult to standardize. Recombinant desmoglein-1 (Dsg1), Dsg3, and BP180 peptides, the main autoantigens in pemphigus or bullous pemphigoid, have been used to develop new quantitative enzyme immunoassays (EIA) for the detection of specific antibodies. The present study was undertaken to evaluate the sensitivity and specificity of these immunoassays and to determine the correlation between the results and the clinical aspects of diseases. Serum samples from patients with pemphigus vulgaris, pemphigus foliaceus, bullous pemphigoid, or mucous membrane pemphigoid, from healthy individuals, and from patients with unrelated autoimmune conditions were tested. Anti-desmoglein reactivity was detected in all the patients with pemphigus and in none of the controls. Patients with the more benign form of cutaneous disease had anti-Dsg1 antibodies, while patients with deeper cutaneous lesions or with mucosal involvement had anti-Dsg3 reactivity also, or exclusively. The BP180-based assay was positive for 66.6% of patients with bullous pemphigoid and for none of the patients with mucous membrane pemphigoid, and no reactivity was detected in the control sera. In conclusion, the anti-Dsg1 and anti-Dsg3 assays are useful in the diagnosis of pemphigus and provide information on the clinical phenotype of the disease. However, the sensitivity of EIA for detection of autoantibodies in bullous pemphigoid should be improved by the use of additional antigens or epitopes.
