Objectives: To compare the distribution of human leucocyte antigen (HLA) class I and II alleles in patients with erosive hand osteoarthritis (EHOA) to that of patients with non-erosive hand OA (non-EHOA) and in healthy Italian Bone Marrow Donors (IBMDs), in order to evaluate possible immunogenetic associations with EHOA. In the EHOA group we also sought possible associations between HLA alleles and disease severity. Methods: Ninety-four patients with EHOA (82 women, 12 men; mean age 61.4 ±± 8.45 years) and 37 with non-EHOA (28 women, nine men; mean age 59.21 ±± 9.07 years) were studied. Disease severity was measured by the number of clinically active joints (NCAJ) and by the radiographic score (RS) using the Kallman scale. HLA typing was undertaken for A, B, C, and DRB1 loci; HLA-DRB1** genotyping was determined using polymerase chain reaction (PCR) with sequence-specific primers. Frequencies were compared with those of the healthy IBMDs. Results: The alleles found more frequently in EHOA patients than in non-EHOA patients and healthy controls were: A23, A26, and A29; B38, B44, and HLA DRB1**01 and **07. The RS was more severe in the EHOA compared to the non-EHOA group (63.60 ±± 23.14 vs. 34.34 ±± 20.24, p < 0.001). Within the EHOA group, HLA-DRB1**07 was associated with a higher RS (67.36 ±± 23 vs. 64.5 ±± 18.5, p == 0.029). Conclusion: In this study of North Italian patients affected with EHOA, the HLA-DRB1**07 allele was found to be associated with both the development and greater severity of the disease.

ObjectiveTo evaluate the diagnostic performance of the tests included in primary Sjogren's syndrome (SS-I) diagnostic criteria (Schirmer I, break-up time, vital dye staining) and to compare them with other examinations related to the ocular surface status.MethodsClinical and cytological data were collected from 177 patients (62 SS-1, 56 non-SS autoimmune diseases, 59 Sicca syndrome). Tear tests included: a validated questionnaire on symptoms, Schirmer I, Jones test, Ferning test, BUT, corneal aesthesiometry, tear clearance test, lissamine green staining, impression conjunctival cytology. Data were statistically evaluated and sensitivity, specificity, likelihood ratio (LR+), receiver-operating characteristics (ROC) curves were calculated for each test.ResultsData showed a poor diagnostic performance of Schirmer test I (sensitivity 0.42; specificity 0.76; LR+1.75) and BUT (sensitivity 0.92; specificity 0.17; LR+1.11) (area under the curve in ROC analysis <0.58). Validated subjective symptoms questionnaire (sensitivity 0.89; specificity 0.72; LR+3.18), Jones test (sensitivity 0.60; specificity 0.88; LR+5), corneal aesthesiometry (sensitivity 0.80; specificity 0.67; LR+2.42), and tear clearance test (sensitivity 0.63; specificity 0.84; LR+3.93), all exhibited a high diagnostic performance (area under the curve in the ROC analysis always >0.70). Lissamine green staining exhibited the best performance (sensitivity 0.63; specificity 0.89; LR+5.72) but the result could be distorted by an incorporation bias.ConclusionsOur data suggest to implement the items for ocular signs and symptoms contained in many SS-I diagnostic criteria with the use of a validated questionnaire, performance of Jones test, corneal aesthesiometry measurement, and tear clearance rate evaluation.Eye (2007) 21, 229–237. doi:10.1038/sj.eye.6702204; published online 6 January 2006 [ABSTRACT FROM AUTHOR]

Objectives: Over the last years ultrasound has shown to be an important tool for evaluating lung involvement, including interstitial lung disease (ILD) a potentially severe systemic involvement in many rheumatic and musculoskeletal diseases (RMD). Despite the potential sensitivity of the technique the actual use is hampered by the lack of consensual definitions of elementary lesions to be assessed and of the scanning protocol to apply. Within the Outcome Measures in Rheumatology (OMERACT) Ultrasound Working Group we aimed at developing consensus-based definitions for ultrasound detected ILD findings in RMDs and assessing their reliability in dynamic images., Methods: Based on the results from a systematic literature review, several findings were identified for defining the presence of ILD by ultrasound (i.e., Am-lines, B-lines, pleural cysts and pleural line irregularity). Therefore, a Delphi survey was conducted among 23 experts in sonography to agree on which findings should be included and on their definitions. Subsequently, a web-reliability exercise was performed to test the reliability of the agreed definitions on video-clips, by using kappa statistics., Results: After three rounds of Delphi an agreement >75 % was obtained to include and define B-lines and pleural line irregularity as elementary lesions to assess. The reliability in the web-based exercise, consisting of 80 video-clips (30 for pleural line irregularity, 50 for B-lines), showed moderate inter-reader reliability for both B-lines (kappa = 0.51) and pleural line irregularity (kappa = 0.58), while intra-reader reliability was good for both B-lines (kappa = 0.72) and pleural line irregularity (kappa = 0.75)., Conclusion: Consensus-based ultrasound definitions for B-lines and pleural line irregularity were obtained, with moderate to good reliability to detect these lesions using video-clips. The next step will be testing the reliability in patients with ILD linked to RMDs and to propose a consensual and standardized protocol to scan such patients., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

In Winter 2020, Italy, and in particular the Lombardy region, was the first country in the Western hemisphere to be hit by the COVID-19 pandemic. Plasma from individuals recovered from COVID-19 (COVID-19 convalescent plasma, CCP) was the first therapeutic tool adopted to counteract the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). In this retrospective cohort study, we report the experience of the city hospital of Mantua, Lombardy region, on the compassionate use of CCP in patients hospitalized for severe COVID-19. Between April 2020 and April 2021, 405 consecutive COVID-19 patients received 657 CCP units with a median anti-SARS-CoV-2 neutralizing antibody (nAb) titer of 160 (interquartile range (IQR), 80−320). Their median age was 68 years (IQR, 56−78 years), and 62% were males. At enrollment, 55% of patients had an increased body mass index (BMI), and 25.6% had at least three comorbidities. The 28-day crude mortality rate was 12.6% (51/405). Young age (<68 years), mild disease (admission to low-intensity departments) and early treatment (<7 days from symptoms onset) with high nAb titer (≥320) CCP were found as independently associated with a favorable response to CCP treatment. No safety concerns were recorded, with a rate of CCP-related adverse reactions (all of mild intensity) of 1.3%. In our real-life experience, the first in the western world, early administration of high-titer CCP was a safe and effective treatment for hospitalized COVID-19 patients.

Hyperimmune plasma from Covid-19 convalescent is a potential treatment for severe Covid-19. We conducted a multicenter one arm proof of concept interventional study. Patients with Covid-19 disease with moderate-to-severe Acute Respiratory Distress Syndrome, elevated C-reactive Protein and need for mechanical ventilation and/or CPAP were enrolled. One to three 250-300 ml unit of hyperimmune plasma (neutralizing antibodies titer ≥1:160) were administered. Primary outcome was 7-days hospital mortality. Secondary outcomes were PaO2/FiO2, laboratory and radiologic changes, as well as weaning from mechanical ventilation and safety. The study observed 46 patients from March, 25 to April, 21 2020. Patients were aged 63, 61% male, of them, 30 were on CPAP and 7 intubated. PaO2/FiO2 was 128 (SD 47). Bilateral infiltrates on chest X-ray was present in 36 patients (84%). Symptoms and ARDS duration were 14 (SD 7) and 6 days (SD 3). Three patients (6.5%) died within 7 days as compared to an expected 15% from the National Statistics and 30% from a small concurrent cohort of 23 patients. The upper one-sided 90%CI was 13.9%, allowing to reject the null hypothesis of a 15% mortality. PaO2/FiO2 increased by 112 units (95%CI 82 to142) in survivors, the chest radiogram severity decreased in 23% (95%CI 5% to 42%); CRP, Ferritin and LDH decreased by 60, 36 and 20% respectively. Weaning from CPAP was obtained in 26/30 patients and 3/7 were extubated. Five serious adverse events occurred in 4 patients (2 likely, 2 possible treatment related). In conclusion, Hyperimmune plasma in Covid-19 shows promising benefits, to be confirmed in a randomized controlled trial. This proof of concept study could open to future developments including hyperimmune plasma banking, development of standardized pharmaceutical products and monoclonal antibodies.

Introduction: Osteoporosis is a chronic condition leading to an increased risk of developing fractures, with high morbidity and mortality in aging population. Efficacy of anti-osteoporotic treatment is based on drug potency but also on compliance and persistence to treatment regimen, which is very low, as already described for other diseases. Teriparatide (TPTD) is the first anabolic agent developed for the treatment of osteoporosis. Since it appears that persistence to Teriparatide declines over time, aim of this pilot multicenter observational study was to evaluate persistence and adherence to TPTD (20 μg daily injection regimen for 18 months) treatment (PATT) in patients affected by severe osteoporosis in an every day clinical practice., Methods: Patients affected by severe osteoporosis were selected among those who referred to 5 different specialized centers for osteoporosis in North, Center and South of Italy. A sample of 475 women with severe postmenopausal osteoporosis treated with TPTD in accordance to the Italian osteoporosis guidelines was included. At the beginning of TPTD treatment patients were instructed on the use of the device by the referring specialist of the center, a resident fellow or a nurse. Bone biochemical markers were evaluated the same morning and after 1, 3, 6, 12 and 18 months. Patients were visited at time 0 and after 6, 12 and 18 months for clinical follow up., Results: The results included observations of 441/475 patients (98% women) who completed the 18 months treatment; mean age for women was 73±8 and for men 65±9. After 6 months of TPTD treatment persistence was of 89,79%, 87,75% after 12 months and 86,85% after 18 months. Adherence was of 100% at 6,12 and 18 months. Total dropouts were 13,15% (71/441), which was usually higher within the first 6 months of TPTD treatment. Most common adverse events (arthralgies 2,7%, dizziness 1,8%, migraine 1,8%, depression 1,6%, hypertension 1,1%) were reported in 62/441 patients (14%) of patients, but were not reason for stopping treatment., Conclusions: The persistence and adherence to TPTD treatment obtained in this multicenter observational real life study was very high as compared to studies performed by others. These encouraging results suggest that different key factors such quality of information, frequency of visits, motivations given to patients, opportunity to call the doctor might play a pivotal role in the high persistence and adherence to TPTD treatment obtained in our study and need to be carefully considered before prescribing chronic anti-osteoporotic therapy.

Aim: To investigate whether systemic lupus erythematosus (SLE) is associated with benign focal liver lesions and vascular liver diseases, since these have been occasionally reported in SLE patients., Methods: Thirty-five consecutive adult patients with SLE and 35 age- and sex-matched healthy controls were evaluated. Hepatic and portal vein patency and presence of focal liver lesions were studied by colour-Doppler ultrasound, computerized tomography and magnetic resonance were used to refine the diagnosis, clinical data of SLE patients were reviewed., Results: Benign hepatic lesions were common in SLE patients (54% vs 14% controls, P < 0.0001), with hemangioma being the most commonly observed lesion in the two groups. SLE was associated with the presence of single hemangioma [odds ratios (OR) 5.05; 95% confidence interval (CI) 1.91-13.38] and multiple hemangiomas (OR 4.13; 95% CI 1.03-16.55). Multiple hemangiomas were associated with a longer duration of SLE (9.9 ± 6.5 vs 5.5 ± 6.4 years; P = 0.04). Imaging prior to SLE onset was available in 9 patients with SLE and hemangioma, showing absence of lesions in 7/9. The clinical data of our patients suggest that SLE possibly plays a role in the development of hemangioma. In addition, a Budd-Chiari syndrome associated with nodular regenerative hyperplasia (NRH), and a NRH associated with hepatic hemangioma were observed, both in patients hospitalized for abdominal symptoms, suggesting that vascular liver diseases should be specifically investigated in this population., Conclusion: SLE is associated with 5-fold increased odds of liver hemangiomas, suggesting that these might be considered among the hepatic manifestations of SLE.

Inflammatory or erosive are terms used interchangeably to define a clinical subset of osteoarthritis of the hand (HOA), targeting interphalangeal joints and characterised by an abrupt onset, marked pain and functional impairment, inflammatory symptoms and signs, including stiffness, soft tissue swelling, erythema, paraesthesiae, mildly elevated C-reactive protein and a worse outcome than non-erosive HOA. This subset is defined radiographically by subchondral erosion, cortical destruction and subsequent reparative change, which may include bony ankylosis. Although the presence of both clinical and radiographic aspects are very suggestive for the diagnosis in most cases, doubts have been recently raised from some studies which, by means of sensitive imaging techniques such as magnetic resonance imaging (MRI) and sonography, had found erosive changes in most patients with HOA, including those without signs of erosions at conventional radiography. However, many findings suggest that subjects with erosive HOA exhibit more inflammatory features than those with non-erosive HOA in different ways, including clinical, laboratory and sonographic aspects. Thus, it is probably preferable to use the double term inflammatory/erosive to better define this particular subset of HOA., (Copyright 2009 Elsevier Ltd. All rights reserved.)

The purpose of this study is to evaluate the intraocular inflammation at a sub clinical level, in patients suffering from Sjogren's syndrome (SS-I) and Rheumatoid Arthritis (RA), to relate it with the ocular surface status and to verify the diagnostic performance of the method. Twenty-eight patients suffering from SS-I, 31 patients suffering from RA and 31 normal subjects matched in age and gender were included in the study. A Kowa 500F laser cell flare meter was utilized to quantify the aqueous cells and flare in vivo, ocular surface inflammation was graded by conjunctival cytology and dosage of serum albumin in tears, eye dryness was scored with Tear Function Index. All data resulted significantly different in both SS-I and RA patients vs. control group and also different comparing SS-I vs. RA patients group, except for the Flare values. A blood-aqueous barrier breakdown occurs either in SS-I and RA patients; the degree of the damage is related with ocular surface inflammation and dryness. We recommend the aqueous flare be analysed in those rheumatic patients where an ocular surface inflammation has been documented.

Objective: To investigate the reliability and validity of the Italian version of ECOS-16 (Assessment of health related quality of life in osteoporosis) in comparison to other questionnaires in postmenopausal women with osteoporosis., Methods: A cross-sectional multicentre study was carried out among postmenopausal women with osteoporosis who were attending primary care centres and hospital outpatient clinics. The patient group included 234 females (mean age 69 years, range 48-89) who presented vertebral fractures due to osteoporosis. The control group consisted of 244 asymptomatic osteoporotic subjects matched for age with the patient group. The psychometric properties of the questionnaires were evaluated in terms of feasibility, validity (construct validity and discriminant validity) and internal consistency. Test-retest reliability was analysed for 196 outpatients who reported that their general health status due to osteoporosis had not changed after one week. In all patients the ECOS-16, the SF-36 (Medical Outcomes Study Short Form-36), EUROQoL (EQ-5D), mini-OQLQ (mini-Osteoporosis Quality of Life Questionnaire), and RMDQ (Roland-Morris Disability Questionnaire) were administered, and all clinical variables and sociodemographic variables were taken into account. Construct and discriminant validity were assessed by Spearman's correlations, the Wilcoxon rank sum test, the Kruskal Wallis test and by receiver operating characteristic (ROC) curves. Internal consistency was evaluated using Cronbach's alpha and the test-retest reliability was evaluated by intra-class correlation coefficients (ICCs)., Results: 96.9% of the patients answered all items of the ECOS-16 questionnaires. The mean administration time was 10 minutes. Factor analysis yielded two factors that accounted for 88.4% of the explained variance in the ECOS-16 questionnaire. The first factor was the ECOS-16 Physical Component Score (PCS) (45.9% of the explained variance) and the second factor was the ECOS-16 Mental Component Score (MCS) (42.4% of the explained variance). The inter-item correlation between the two factors was 0.48. Significant correlations were found between the scores of similar domains or subscales of the ECOS-16 and SF-36, EQ-5D and mini-OQLQ, supporting the concept of convergent construct validity. The total ECOS-16 score progressively increased with the number of prevelant vertebral fractures (p<0.001) and the effect of the first fracture was already statistically significant (p<0.01). On ROC curve analysis the total ECOS-16 score showed the highest performance among the different questionnaires in discriminating between patients with vertebral fractures and controls with no fractures. In the reliability study, internal consistency within the domain of ECOS-16 was generally good, with Chronbach's alpha values ranging from 0.81 to 0.89. Test-retest reliability was 0.87 for the total ECOS-16 score., Conclusion: The Italian version of the ECOS-16 questionnaire was demonstrated to have good psychometric properties and could offer a useful tool in research and routine clinical practice to evaluate HRQoL in post-menopausal women with osteoporosis. A full validation of the psychometric properties will require data on its sensitivity to change.

Objective: To verify whether ocular surface tests other than those included in primary Sjögren's syndrome (SS-I) classification criteria (Schirmer I, Break up Time, vital dye staining) may contribute to SS I diagnosis., Methods: Two hundred and sixty-two patients (78 SS-1, 91 non-SS autoimmune diseases, 93 Sicca syndrome) filled a validated questionnaire on symptoms and were evaluated by Schirmer test without (Schirmer I) and with (Jones test) topical anaesthesia, Break Up Time (BUT), corneal aesthesiometry, tear clearance rate, vital dye (lissamine green) staining, impression conjunctival cytology, concentration of tear lysozyme and lactoferrin. Thresholds were selected from Receiver Operating Curves; sensitivity, specificity, likelihood ratio (LR+), predictive values were calculated for each test. A logistic regression model was constructed representing the best diagnostic index for SS., Results: Data showed a poor diagnostic performance of Schirmer test I (LR+ 1.38) and BUT (LR+ 1.05); results from lissamine green staining may be unreliable due to incorporation bias. Tear lactoferrin (LR+ 4.52), Jones test (LR+ 6.24), tear lysozyme (LR+ 8.0), symptom questionnaire (LR+ 8.62), tear clearance rate (LR+ 18.73) and corneal aesthesiometry (LR+ 20.96) exhibited high diagnostic performance also taken together in the regression model., Conclusion: Because many of the tests we have screened in this study can be carried out by a trained ophthalmologist in any clinical setting, we recommend that ocular surface impairment is studied with the combination of tests proved to be helpful for the SS I diagnosis.

Several authors have found a relationship between vitamin D status and bone mineral density (BMD). To our knowledge, no previous studies on this topic have been carried out on the Italian postmenopausal population. We studied this relationship retrospectively in 156 Italian postmenopausal women. We also investigated the relationship between parathyroid hormone (PTH) and BMD. Measurements of BMD were taken at the lumbar spine and upper femur by dual X-ray absorptiometry. Serum 25(OH)D (calcidiol), 1,25(OH)2D (calcitriol), PTH, calcium, phosphorus, creatinine, osteocalcin and urinary calcium and phosphorus were measured according to the current laboratory methods of analysis. We found a positive statistically significant correlation between BMD, both at the spine and hip, and 25(OH)D, and a negative statistically significant correlation between BMD and PTH. No statistically significant correlation was found between BMD and 1,25(OH)2D. Crude logistic regression showed age, 25(OH)D and PTH were significant predictors of low BMD, while 1,25(OH)2D was not. Backward logistic regression showed 25(OH)D was the best predictive model for spine osteoporosis together with age, and on its own it was the best predictive model for femoral neck osteoporosis.

Objective: The international criteria for primary Sjögren's Syndrome (SS I) diagnosis (Vitali et al. 2002) include the Schirmer test I and vital dye staining as tests for ocular surface involvement, but diagnosis can be reached also when the item for ocular signs is not satisfied. The purpose of our study was to evaluate the ocular surface in patients with Sjögren's Syndrome, non-Sjögren's autoimmune diseases and Sicca Syndrome, to understand whether the SS I diagnosis can be targeted also on other tests related to the ocular surface status., Methods: Clinical and cytological data were collected from 122 patients: 40 patients had diagnosis of Primary Sjögren's Syndrome, 51 a non Sjögren's autoimmune disease and 31 had symptoms of dry eye. A validated questionnaire on symptoms was filled by each patient; clinical tests included: Schirmer test I, Jones test, Ferning test, Break Up Time, corneal aesthesiometry, tear clearance test, vital dye staining of the ocular surface, scraping and impression conjunctival cytology. Data were statistically evaluated by using SPSS software and Mann-Whitney analysis on unpaired data., Results: Data show that the subjective symptoms score, tear production, tear turnover, corneal sensitivity and ocular surface integrity are affected in SS I patients, with a statistically significant difference when matched to the other two groups., Conclusions: Our results suggest to enlarge the spectrum of ocular surface analysis, to support and orient a differential diagnosis among the autoimmune diseases.

In the last two decades, several non-invasive techniques have been developed to measure bone density at axial and peripheral skeletal sites. The dual-energy X-ray absorptiometry (DXA) technique allows accurate measurement of bone density, but does not provide information about the structural and qualitative features of bone, which play an important role in fracture risk determination. Increasing interest in quantitative ultrasonography (QUS) has recently developed; it may be considered a safe and quite inexpensive diagnostic technique. Ultrasound devices routinely measure two parameters: broadband ultrasound attenuation (BUA) and speed of sound (SOS). Two other parameters, stiffness and index of consistency (QUI), can be derived from BUA and SOS. SOS is influenced by the elasticity of bone as well as by its density. BUA is determined by mechanisms of diffraction, scattering and absorption in the bone, marrow and soft tissue. Absorption predominates in cortical bone and scattering in trabecular bone. BUA is a measure of the approximately linear frequency dependence of ultrasound attenuation. Several QUS devices are now available for clinical use for measuring various parameters at skeletal sites with different contents of trabecular and cortical bone. Standardization of instruments is one of the major limitations of this technique today. Many studies have demonstrated that BUA and SOS, measured at any level, can discriminate normal subjects from osteoporotic patients. Moreover, there is evidence documenting the ability of QUS to predict osteoporotic fracture risk and to give further BMD-independent information on bone. QUS at the heel can now be considered as an alternative technique to identify subjects with a high risk of bone fragility. Further studies are needed for better definition of the role of QUS in clinical practice.

Unlabelled: Mineral density and bone geometry are the two main biomechanical factors related to bone resistance to stress., Objective: In this study we assess whether differences in the proximal femur geometry (PFG) characterize different types of osteoporotic fractures., Methods: We studied 533 postmenopausal women aged 50 - 85. They were divided into four groups matched for bone mineral density at the femoral neck; without fractures (165), vertebral fractures (139), trochanteric fractures (102), and hip fractures (127). Dual X-Ray absorptiometry (DXA) scans at the spine and at the hip were carried out to measure bone mineral density and the DXA images were used to define the proximal femur geometry parameters of the hip., Results: Age, height, vertebral BMD and PFG parameters (i.e. femoral neck-shaft angle (NSA) and hip axis length (HAL) were different when all four groups were compared by the Anova test. Patients with vertebral fractures were then compared by multivariate analysis to those with trochanteric fractures. The variables that discriminated the two groups were: age, age at menopause, weight, height, and vertebral BMD, but not PFG. Comparing vertebral to hip fractures the distinguishing variables were: vertebral BMD, height, NSA and HAL. We found that hip fractures had longer HAL and wider NSA than vertebral fractures, whereas no statistically significant differences were found between trochanteric fractures and vertebral fractures concerning PFG., Conclusions: These data indicate that differences in PFG parameters might have a role in predisposing to femoral neck fracture.
