    Objective: To investigate the deleterious effects of air pollutants exposure in the Sao Paulo metropolitan region on semen quality in systemic lupus erythematosus (SLE). Methods: A seven-years longitudinal repeated-measures panel study was performed at the Laboratory of Experimental Air Pollution and Rheumatology Division. Two semen samples from 28 post-pubertal SLE patients were analyzed. Daily concentrations of air pollutants exposure: PM10, SO2, NO2, ozone, CO, and meteorological variables were evaluated on 90 days before each semen collection dates using generalized estimating equation models. Results: Intravenous cyclophosphamide (IVCYC) and ozone had an association with a decrease in sperm quality of SLE patients. IVCYC was associated with decreases of 64.3 million of spermatozoa/mL (95% CI 39.01-89.65; p = 0.0001) and 149.14 million of spermatozoa/ejaculate (95% CI 81.93-216.38; p = 0.017). With regard to ozone, the most relevant adverse effects were observed from lags 80-88, when the exposure to an interquartile range increase in ozone 9-day moving average concentration led to decreases of 22.9 million of spermatozoa/mL (95% CI 5.8-40.0; p = 0.009) and 70.5 million of spermatozoa/ejaculate (95% CI 12.3-128.7; p = 0.016). Further analysis of 17 patients that never used IVCYC showed association between exposure to ozone (80-88 days) and decrease of 30.0 million of spermatozoa/mL (95% CI 7.0-53.0; p = 0.011) and 79.0 million of spermatozoa/ejaculate (95% CI 2.1-155.9; p = 0.044). Conclusion: Ozone and IVCYC had a consistent adverse effect on semen quality of SLE patients during spermatogenesis. Minimizing exposure to air pollution should be taken into account, especially for patients with chronic systemic inflammatory diseases living in large cities.

    (2016) ARAÚJO, Priscila; CARVALHO, Márcio Guilherme Nunes; VAN WEELDEN, Marlon; LOURENÇO, Benito; QUEIROZ, Lígia Bruni; SILVA, Clovis Artur
    Abstract Objective: To evaluate alcohol/tobacco and/or illicit drug misuse in Chronic Diseases (CDs). Methods: A cross-sectional study with 220 CDs adolescents and 110 healthy controls including: demographic/anthropometric data; puberty markers; modified questionnaire evaluating sexual function, alcohol/smoking/illicit drug misuse and bullying; and the physician-conducted CRAFFT (car/relax/alone/forget/friends/trouble) screen tool for substance abuse/dependence high risk. Results: The frequencies of alcohol/tobacco and/or illicit drug use were similar in both groups (30% vs. 34%, p=0.529), likewise the frequencies of bullying (42% vs. 41%, p=0.905). Further analysis solely in CDs patients that used alcohol/tobacco/illicit drug versus those that did not use showed that the median current age [15 (11–18) vs. 14 (10–18) years, p <0.0001] and education years [9 (5–14) vs. 8 (3–12) years, p <0.0001] were significant higher in substance use group. The frequencies of Tanner 5 (p <0.0001), menarche (p <0.0001) and spermarche (p=0.001) were also significantly higher in patients with CDs that used alcohol/tobacco/illicit, likewise sexual activity (23% vs. 3%, p <0.0001). A trend of a low frequency of drug therapy was observed in patients that used substances (70% vs. 82%, p=0.051). A positive correlation was observed between CRAFFT score and current age in CD patients (p=0.005, r=+0.189) and controls (p=0.018, r=+0.226). Conclusions: A later age was evidenced in CDs patients that reported licit/ilicit drug misuse. In CDs adolescent, substance use was more likely to have sexual intercourse. Our study reinforces that these patients should be systematically screened by pediatricians for drug related health behavioral patterns.

    Background: Rheumatic diseases in children are associated with significant morbidity and poor health-related quality of life (HRQOL). There is no health-related quality of life (HRQOL) scale available specifically for children with less common rheumatic diseases. These diseases share several features with systemic lupus erythematosus (SLE) such as their chronic episodic nature, multi-systemic involvement, and the need for immunosuppressive medications. HRQOL scale developed for pediatric SLE will likely be applicable to children with systemic inflammatory diseases. Findings: We adapted Simple Measure of Impact of Lupus Erythematosus in Youngsters (SMILEY (c)) to Simple Measure of Impact of Illness in Youngsters (SMILY (c)-Illness) and had it reviewed by pediatric rheumatologists for its appropriateness and cultural suitability. We tested SMILY (c)-Illness in patients with inflammatory rheumatic diseases and then translated it into 28 languages. Nineteen children (79% female, n= 15) and 17 parents participated. The mean age was 12 +/- 4 years, with median disease duration of 21 months (1-172 months). We translated SMILY (c)-Illness into the following 28 languages: Danish, Dutch, French (France), English (UK), German (Germany), German (Austria), German (Switzerland), Hebrew, Italian, Portuguese (Brazil), Slovene, Spanish (USA and Puerto Rico), Spanish (Spain), Spanish (Argentina), Spanish (Mexico), Spanish (Venezuela), Turkish, Afrikaans, Arabic (Saudi Arabia), Arabic (Egypt), Czech, Greek, Hindi, Hungarian, Japanese, Romanian, Serbian and Xhosa. Conclusion: SMILY (c)-Illness is a brief, easy to administer and score HRQOL scale for children with systemic rheumatic diseases. It is suitable for use across different age groups and literacy levels. SMILY (c)-Illness with its available translations may be used as useful adjuncts to clinical practice and research.

    Subclinical pulmonary abnormalities in childhood-onset systemic lupus erythematosus patients
    (2016) VEIGA, C. S.; COUTINHO, D. S.; NAKAIE, C. M. A.; CAMPOS, L. M. A.; SUZUKI, L.; CUNHA, M. T.; LEONE, C.; SILVA, C. A.; RODRIGUES, J. C.
    Objective The aims of this study were to analyze the pulmonary function of childhood-onset systemic lupus erythematosus (cSLE) patients and to identify possible correlations between the high-resolution computed chest tomography (HRCT) score, disease activity, disease cumulative damage, and the participants' quality of life. Methods Forty cSLE patients, median age: 14.1 years (range: 7.4-17.9), underwent spirometry and plethysmography. Carbon monoxide diffusing capacity (DLCO), HRCT, disease activity, disease cumulative damage, and quality of life were assessed. Results Pulmonary abnormalities were evident in 19/40 (47.5%) cSLE patients according to spirometry/DLCO. Forced expired volume in one second (FEV1%) was the parameter most affected (30%). The HRCT showed some abnormality in 22/30 patients (73%), which were minimal in 43%. Signs of airway affects were found in 50%. Twelve patients were hospitalized due to cSLE-related pulmonary complications before the study began (median discharge: 2.1 years earlier). Total lung capacity (TLC%), vital capacity (VC%), forced vital capacity (FVC%), and FEV1% were significantly lower in the group with hospitalization compared to the group without hospitalization (p=0.0025, p=0.0022, p=0.0032, and p=0.0004, respectively). Of note, DLCO was positively correlated with disease duration (r=+0.4; p=0.01). The HRCT-score was negatively correlated with FEV1/VC (r=-0.63; p=0.0002), FEV1 (r=-0.54; p=0.018), FEF25%-75% (r=-0.67; p<0.0001), and HRCT-score was positively correlated with resistance (r=+0.49; p=0.0056). Conclusions Almost half of patients with cSLE had subclinical pulmonary abnormalities, especially airway abnormalities. The cSLE-related pulmonary complications seem to determine long-term functional damage.

    Safety and immunogenicity of influenza A(H3N2) component vaccine in juvenile systemic lupus erythematosus
    (2023) AIKAWA, Nadia Emi; BORBA, Eduardo Ferreira; BALBI, Verena Andrade; SALLUM, Adriana Maluf Elias; BUSCATTI, Izabel Mantovani; CAMPOS, Lucia Maria Arruda; KOZU, Katia Tomie; GARCIA, Cristiana Couto; CAPAO, Artur Silva Vidal; PROENCA, Adriana Coracini Tonacio de; LEON, Elaine Pires; DUARTE, Alberto Jose da Silva; LOPES, Marta Heloisa; SILVA, Clovis Artur; BONFA, Eloisa
    Introduction Seasonal influenza A (H3N2) virus is an important cause of morbidity and mortality in the last 50 years in population that is greater than the impact of H1N1. Data assessing immunogenicity and safety of this virus component in juvenile systemic lupus erythematosus (JSLE) is lacking in the literature.Objective To evaluate short-term immunogenicity and safety of influenza A/Singapore (H3N2) vaccine in JSLE.Methods 24 consecutive JSLE patients and 29 healthy controls (HC) were vaccinated with influenza A/Singapore/INFIMH-16-0019/2016(H3N2)-like virus. Influenza A (H3N2) seroprotection (SP), seroconversion (SC), geometric mean titers (GMT), factor increase in GMT (FI-GMT) titers were assessed before and 4 weeks post-vaccination. Disease activity, therapies and adverse events (AE) were also evaluated.Results JSLE patients and controls were comparable in current age [14.5 (10.1-18.3) vs. 14 (9-18.4) years, p = 0.448] and female sex [21 (87.5%) vs. 19 (65.5%), p = 0.108]. Before vaccination, JSLE and HC had comparable SP rates [22 (91.7%) vs. 25 (86.2%), p = 0.678] and GMT titers [102.3 (95% CI 75.0-139.4) vs. 109.6 (95% CI 68.2-176.2), p = 0.231]. At D30, JSLE and HC had similar immune response, since no differences were observed in SP [24 (100%) vs. 28 (96.6%), p = 1.000)], SC [4 (16.7%) vs. 9 (31.0%), p = 0.338), GMT [162.3 (132.9-198.3) vs. 208.1 (150.5-287.8), p = 0.143] and factor increase in GMT [1.6 (1.2-2.1) vs. 1.9 (1.4-2.5), p = 0.574]. SLEDAI-2K scores [2 (0-17) vs. 2 (0-17), p = 0.765] and therapies remained stable throughout the study. Further analysis of possible factors influencing vaccine immune response among JSLE patients demonstrated similar GMT between patients with SLEDAI < 4 compared to SLEDAI >= 4 (p = 0.713), as well as between patients with and without current use of prednisone (p = 0.420), azathioprine (p = 1.0), mycophenolate mofetil (p = 0.185), and methotrexate (p = 0.095). No serious AE were reported in both groups and most of them were asymptomatic (58.3% vs. 44.8%, p = 0.958). Local and systemic AE were alike in both groups (p > 0.05).Conclusion This is the first study that identified adequate immune protection against H3N2-influenza strain with additional vaccine-induced increment of immune response and an adequate safety profile in JSLE.
