Incidence of cervical human papillomavirus infection in systemic lupus erythematosus women.

Objectives Our objective was to study the incidence, persistence and clearance of human papillomavirus infection in systemic lupus erythematosus women and assess risk factors for persistence of human papillomavirus infection. Methods We carried out a prospective, observational cohort study of 127 systemic lupus erythematosus women. Patients were evaluated at baseline and at three years. Traditional and systemic lupus erythematosus women-related disease risk factors were collected. Gynaecological evaluations and cervical cytology screening were made. Human papillomavirus detection and genotyping were made by polymerase chain reaction and linear array. Results The cumulative prevalence of human papillomavirus infection increased from 22.8% at baseline to 33.8% at three years; p = < 0.001: 20.1% of patients experienced 43 incident infections. The risk of any human papillomavirus infection was 10.1 per 1000 patient-months. At three years, 47 (88.6%) prevalent infections were cleared. Independent risk factors associated with incident human papillomavirus infection included more lifetime sexual partners (odds ratio = 1.8, 95% confidence interval = 1.11-3.0) and cumulative cyclophosphamide dose (odds ratio = 3.9, 95% confidence interval = 1.2-12.8). Conclusions In systemic lupus erythematosus women, the cumulative prevalence of human papillomavirus infection, including high risk-human papillomavirus and multiple human papillomavirus infections, may increase over time. Most persistent infections were low risk-human papillomavirus. The number of lifetime sexual partners and the cumulative cyclophosphamide dose were independently associated with incident human papillomavirus infection.

Lack of association between serum 25-hydroxyvitamin D levels and cervical human papillomavirus infection in systemic lupus erythematosus.

Our objective was to evaluate whether vitamin D deficiency is associated with cervical human papilloma virus (HPV) infection in women with SLE. This is a cross-sectional study of 67 women with SLE. A structured questionnaire was administered to ascertain the possible risk factors associated with cervical HPV infection. A gynaecological evaluation and cervical cytology screening were made. HPV detection and genotyping was made by PCR and linear array assay. Serum 25 hydroxyvitamin D levels were quantified by chemiluminescence immunoassay. Mean age and disease duration were 44.8 ± 10.6 and 42.5 ± 11.8 years, respectively. Demographic characteristics were similar in patients with and without deficiency (<20 ng/ml and ≥20 ng/ml). There were 28.4% of women with cervical HPV infection and 68.4% had high-risk HPV infections. Patients with 25 hydroxyvitamin D levels <20 ng/ml had a higher prevalence of cervical HPV infection than those with levels ≥20 ng/ml (30.7% vs. 25.8%; p = 0.72). We found no significant difference when high-risk HPV infection was evaluated (36.8% vs. 31.5%; p = 0.73). In conclusion, women with SLE have a high prevalence of vitamin D deficiency and cervical HPV infection. However, we found no association between vitamin D deficiency and cervical HPV.

Hedonic perception of odors in children aged 5-8 years is similar across 18 countries: Preliminary data.

OBJECTIVE: Olfactory preference emerges very early in life, and the sense of smell in children rapidly develops until the second decade of life. It is still unclear whether hedonic perception of odors is shared in children inhabiting different regions of the globe. METHODS: Five-hundred ten healthy children (N = 510; ngirls = 256; nboys = 254) aged from 5 to 8 years from 18 countries rated the pleasantness of 17 odors. RESULTS: The hedonic perception of odors in children aged between 5 and 8 years was rather consistent across 18 countries and mainly driven by the qualities of an odor and the overall ability of children to label odorants. CONCLUSION: Conclusions from this study, being a secondary analysis, are limited to the presented set of odors that were initially selected for the development of U-Sniff test and present null findings for the cross-cultural variability in hedonic perception of odors across 18 countries. These two major issues should be addressed in the future to either contradict or replicate the results presented herewith. This research lays fundament for posing further research questions about the developmental aspects of hedonic perception of odors and opens a new door for investigating cross-cultural differences in chemosensory perception of children.

Irritable bowel syndrome-type symptoms in female patients with mild systemic lupus erythematosus: frequency, related factors and quality of life.

BACKGROUND: Irritable bowel syndrome (IBS) impairs quality of life (HRQOL), as does systemic lupus erythematosus (SLE). Both are more common in women and are associated with fibromyalgia (FM). However, the relationship between IBS and SLE and its impact on HRQOL has not been explored. Therefore, we aimed to study the frequency and features likely to influence the presence of IBS-type symptoms in SLE and their impact on HRQOL. METHODS: Female patients with SLE were studied. The presence of IBS-type symptoms and bowel habit subtype were established by Rome III criteria and HRQOL was assessed using the SF-36. Fibromyalgia and depression were assessed using the American College of Rheumatology criteria and CES-D scale, respectively. KEY RESULTS: A total of 105 consecutive patients (43.62 ± 11.34 years old) were included; 48.6% had IBS-type symptoms (SLE+IBS) and were classified as IBS-C: 23.5%, IBS-D: 37.3%, and IBS-M: 39.2%. In addition, 23.8% had FM. SLE+IBS vs Non-IBS SLE patients had higher SLE activity scores (2.55 ± 1.65 vs 1.74 ± 2.19; p = 0.03), were more likely to have FM (33.0% vs 14.8%; p = 0.02) and depression (41.1% vs 25.9%, p = 0.04). Logistic multivariate analysis showed that IBS-type symptoms were associated with FM (OR = 2.85, 95% CI: 1.11-7.43) and depression (OR = 1.07, 95% CI: 1.02-1.13). Finally, SLE+IBS vs Non-IBS SLE patients had lower SF-36 scores (49.65 ± 18.57 vs 62.67 ± 18.14; p = 0.02). CONCLUSIONS & INFERENCES: IBS-type symptoms are highly prevalent among women with SLE and are associated with FM and depression. SLE+IBS patients had worse HRQOL vs Non-IBS SLE, independently of FM status. We suggest that treating IBS symptoms may improve HRQOL in women with SLE.

Lack of subclinical myocardial ischaemia in Mexican patients with systemic lupus erythematosus without traditional risk factors for coronary artery disease.

The objective of this study was to analyse whether patients with systemic lupus erythematosus (SLE) without traditional risk factors for coronary artery disease (CAD) develop subclinical myocardial ischaemia in the first years after diagnosis. A cross-sectional analysis of a cohort of 200 female SLE patients was conducted. We selected those patients who fulfilled the American College of Rheumatology (ACR) SLE criteria and had no traditional risk factors for CAD, including diabetes mellitus, hypertension, obesity, hyperlipidemia, and smoking. After an initial clinical and laboratory examination, patients were evaluated using a baseline echocardiogram and a dobutamine and atropine stress echocardiogram to search for subclinical myocardial ischaemia. Forty-one patients were included in the study. The mean age at the time of the study was 34.5 +/- 9.56 years (mean +/- SD). The mean age at diagnosis was 30.3 +/- 9.39 years. The mean time from diagnosis was 3.9 +/- 3.3 years. Baseline disease activity index (MEX-SLEDAI score) showed that 92.6% of patients had disease activity, although most patients had mild activity. A dobutamine and atropine stress echocardiogram was performed in 40 patients. All 40 patients had negative tests for subclinical myocardial ischaemia. Patients without traditional risk factors for CAD do not have an increased risk for subclinical myocardial ischaemia in the first years after diagnosis. A longitudinal follow-up study of these patients is needed to confirm our findings and assess if additional non-traditional risk factors for CAD increase the risk for myocardial ischaemia.
