Ophthalmic involvement is the most debilitating complication of Behcet’s disease (BD). The aim of the current study is to report on the efficacy and safety of a long-term use of interferon alpha-2a (IFNα-2a) in the treatment of refractory ophthalmic BD in the Azari population of Iran. We retrospectively analyzed the clinical data of 12 patients with ophthalmic BD who were under IFNα-2a therapy. All these patients had previously been treated unsuccessfully with corticosteroid and at least one conventional immunosuppressive drug. IFNα-2a was administered at a daily dose of 6 million IU (MIU). After controlling the symptoms, a dose of 6 MIU three times per week was applied for 8–12 weeks, and then, a dose of 3 MIU was administered three times per week as a subcutaneous injection. Visual acuity and total inflammatory activity index (TIAI) were used in order to assess the response to the treatment. Response to the treatment and complete eye remission were obtained in 10 (83.3 %) and 7 (58.3 %) patients, irrespectively. Improvement or stabilization of visual acuity was observed in 18 (81.8 %) out of 22 eyes. After a mean period of 29.6 months, the use of IFNa-2a was discontinued in eight (66.7 %) patients. Unaltered vision for 2 years after IFNa-2a discontinuation happened in eight (100 %) patients. IFNa-2a is probably effective and safe in the treatment of refractory sight-threatening ophthalmic BD in the Azari population of Iran. 相似文献

OBJECTIVE: To assess the clinimetric properties of a new health-related quality of life (HRQOL) instrument, the World Health Organization Disability Assessment Schedule II (WHODAS II), in patients with early inflammatory arthritis. METHODS: Internal consistency as well as criterion, construct, and discriminative validity of the WHODAS II were assessed in 172 patients with early inflammatory arthritis who completed the WHODAS II, the Medical Outcomes Study Short Form 36 (SF-36), and other measures of disease severity, functioning, pain, depression, and resource use. Test-retest reliability of the WHODAS II was assessed by having a subset of 20 patients complete the WHODAS II a second time, 1 week after the first assessment. RESULTS: The WHODAS II had high internal consistency (Cronbach's alpha = 0.96 for patients working or in school and 0.93 for patients not working or in school). Test-retest intraclass correlation coefficients of the WHODAS II total score and subscales ranged from 0.82-0.96. The WHODAS II total score was strongly correlated with the SF-36 physical component score (Kendall's tau-b 0.51, P < 0.001) and moderately correlated with the SF-36 mental component score (tau-b 0.43, P < 0.001). WHODAS II correlations with disease outcomes ranged from Kendall's tau-b 0.15-0.55. The WHODAS II significantly differentiated between every aspect of disease severity assessed with the exception of measures of health resource use. CONCLUSION: The WHODAS II is a valid and reliable measure of HRQOL in cross-sectional studies of patients with early inflammatory arthritis. Research is still required to investigate potential item redundancy and determine its usefulness in longitudinal studies. 相似文献

More than 4.5 million children have been conceived by in vitro fertilization (IVF). Interestingly, singleton IVF offspring born at term have an increased incidence of low birth weight. The mechanism responsible for the lower birth weight is unknown, but alterations in placental function are possible. Hence, the goal of our study was to examine placental growth and function in mice generated in vivo or in vitro. To assess placental function, blastocysts were generated by IVF or produced by natural mating (control group); both IVF and control blastocysts were transferred to pseudopregnant recipients. Placental weights did not differ at embryonic d 15.5 (E15.5) but were increased at E18.5 in the IVF group (25.4%, P < 0.001) compared with control. Proliferation was increased in IVF placentae, whereas overall placental gross morphology and apoptosis were not affected. Both fetal weights (16.4% lower at E15.5 and 8.8% lower at E18.5, P < 0.05) and fetal to placental ratios were lower (P < 0.001) in the IVF compared with the control group at both time points, whereas birth weights did not differ. At E18.5, the mRNA for selected glucose, system A amino acid transporters, and imprinted genes were down-regulated in IVF placentae. GLUT3 protein level was decreased in the IVF group (P < 0.05). Importantly, intrajugular injections of (14)C-methyl-D-glucose or (14)C-MeAIB tracers (n = 6 litters per group) showed that placental transport of glucose and amino acids were 24.8% (not significant) and 58.1% (P < 0.05) lower in the IVF group. Fetal accumulation of glucose was not different, but amino acid accumulation was significantly (36 %) lower in IVF fetuses (P < 0.05). We conclude that IVF alters both fetal and placental growth and, importantly, decreases placental transport efficiency in mice conceived by IVF. 相似文献

In order to teach suitable feeding and hygiene practices to a group of randomly selected Qashqa'i tribe families with 406 children aged 0-59 months, a culturally appropriate community-based education intervention approach was used. To assess the impact of the intervention on the study group, another group of families with 405 children were randomly selected to serve as the controls. At the beginning of the intervention programme both groups of children had access to a similar diet, consisting of cereals, beans, oil, sugar, milk and yoghurt. Baseline data, age, gender, weight, height and mean arm circumference (MAC), were obtained before the intervention. Using Hubley's behavioural change model, the components of which deal with beliefs, attitudes, subjective norms and enabling factors, the research team studied the behaviour of the family members and tried to change their nutritional behaviour. This was achieved by designing a suitable education programme to be carried out for 12 months. During the programme, families were instructed to follow different methods of food preparation and cooking practices. The final data were collected 3 months after the end of the intervention programme. The results indicated that the children in the study group gained: 1.16 (sd 1.2) kg body weight, 0.033 (sd 0.05) m in height, 0.0067 (sd 0.015) m in MAC, 0.8 (sd 1) in weight-for-age Z-score, 0.97 (sd 1.7) in height-for-age Z-score and 0.28 (sd 1.8) in weight-for-height Z-score by the end of the study. The corresponding values for the control group were 0.42 (sd 1.0), 0.0167 (sd 0.047), 0.0017 (sd 0.012), 0.35 (sd 1.1), 0.56 (sd 1.5) and 0.014 (sd 1.6) respectively and the differences were statistically significant (P<0.05). These findings suggest that educational interventions involving parents and/or other family members who might play a role in the care behaviour and care resources are important in feeding the children energy- and protein-enriched, hygienic, simple and cheap foods. Such practices could improve child growth even under conditions of poverty. 相似文献

Background: The familial clustering of rheumatoid arthritis (RA) in first and second degree relatives of patients supports the role of genetic factors. The proportion of heredity in its development is roughly 60%; however, most individuals closely related to someone with RA do not get the disease. Considering the lack of sufficient data on the familial aggregation of RA in Iran, we designed this study for clarifying the familial prevalence of RA. Objective: To determine the prevalence of RA among relatives of patients with RA and to evaluate the mean disease onset age in relatives. Methods: In a longitudinal study from July 2008 to July 2010, we followed 210 unrelated patients with RA and their first and second degree relatives (FDR+ and SDR+), by interviewing and physical examination of those with symptoms, to ascertain prevalence. Familial RA was defined by presence of at least two siblings fulfilling the 1987 ACR criteria for RA. Results: We demonstrated that 17.6% of patients have at least one affected relative. The prevalence of RA in the family of studied patients was 0.83% (42 people). Thirty‐two in FDR+ and 10 people in SDR+ (2.53% and 0.26% of all family), also 1.12% in female relatives and 0.39% in male relatives had RA. The odds ratio for FDR/SDR was 2.52. The mean age at disease onset in relatives was 42.30 ± 1.51 years in FDR+ and 34.40 ± 2.10 years in the SDR+ group (0.03). Conclusion: The risk of RA is greatest in FDR+ and is likely to be due to a combination of inherited and environmental factors. 相似文献

Genetic factors that predispose individuals to Behcet’s disease (BD) are considered to play an important role in the development
of the disease. The serum level of tumor necrosis factor (TNF) is elevated in patients with BD, and a dramatic response to
anti-TNF-α antibody treatment further supports the role of TNF in BD. We investigated the distribution of TNF-α promoter −1031T/C
and −308G/A polymorphisms in 53 BD patients of Iranian Azeri Turks and 79 matched healthy controls, via the PCR–RFLP technique.
The frequency of the TNF-α −1031C allele was significantly higher in Behcet’s patients than in healthy controls (p < 0.0001, OR = 3.08; 95% CI = 1.73–5.47), whereas the frequency of the TNF-α −308A allele was similar in the two compared
groups. The frequency of CG haplotype was significantly higher (p < 0.0001, OR = 3.42; 95% CI = 1.89–6.18), and that of the TA haplotype was significantly lower in BD patients than in healthy
controls. These results suggest that TNF-α is a susceptibility gene for BD in patients from Iranian Azeri Turk ethnic group. 相似文献
