Beyond the symptoms: Personalizing giant cell arteritis care through multidimensional patient reported outcome measure.

BACKGROUND: Giant Cell Arteritis (GCA) is the commonest form of systemic vasculitis in people over the age of 50. Published research highlighted the lack of a disease-specific patient reported outcomes (PROMs) for GCA. OBJECTIVES: To assess the validity, reliability and responsiveness to change of a devised disease specific patient self-reported outcome measures questionnaire for Giant Cell Arteritis (GCA). METHODS: The GCA-PROMs was conceptualized based on frameworks outlined in the OMERACT developed core set of Outcome Measures for Large-Vessel Vasculitis and the guiding principles of the FDA guidance. Initially, cognitive interviews were conducted to identify item pool of questions. Item selection and reduction was achieved based on patients as well as an interdisciplinary group of specialists. Rasch and internal consistency reliability analyses were implemented. RESULTS: A total of 54 GCA patients completed the questionnaire. The GCA-PROMs questionnaire was reliable as demonstrated by a high standardized alpha (0.878-0.983). Content construct assessment of the GCA-PROMs functional disability and QoL revealed significant correlation (p< 0.01) with both HAQ and EQ-5D. Changes in functional disability, QoL showed significant (p< 0.01) variation with diseases activity status in response to therapy. CONCLUSIONS: The developed GCA-PROMs questionnaire is a reliable and valid instrument for assessment of GCA patients. A stratified treatment regimen depending on the individual patient's risk factors as well as preferences and associated comorbidities is the best approach to tailored patient management.

Corrigendum to "Assessment the using of silica nanoparticles (SiO2NPs) biosynthesized from rice husks by Trichoderma harzianum MZ066609 as water lead adsorbent for immune status of Nile tilapia (Oreochromis niloticus)" [Saudi J. Biol. Sci. 28(9) (2021) 5119-5130].

Assessment the using of silica nanoparticles (SiO2NPs) biosynthesized from rice husks by Trichoderma harzianum MF780864 as water lead adsorbent for immune status of Nile tilapia (Oreochromis niloticus).

Rice husks (RHs) was used as a substrate for biosynthesis of high-value Silica nanoparticles (SiO2NPs). An isolate of Trichoderma harzianum MF780864 (T. harzianum) was isolated and identified based on the Internal Transcribed Spacers (ITS) sequences; it showed the potentiality to induce SiO2NPs in the process of RHs biotransformation. SiO2NPs were produced extracellularly and their size was of about 89 nm. SiO2NPs characterized by oval, rod and cubical particles by using Transmission Electron Microscope (TEM).The Fourier transform infrared spectroscopy (FTIR) confirmed the presence of various functional groups of biomolecules and capping protein, encapsulating SiO2NPs. Water and fish samples were collected from private fish farms in El-Sharkia Governorate, Egypt. Lead (Pb) was detected from water and fish samples at its highest concentration at about 0.088 mg/L. The adsorption capacity of Pb by SiO2NPs was evaluated by testing different concentrations of SiO2NPs viz. 1, 2, and 3 mg/L, wherein 1 mg/L revealed the highest Pb adsorption efficiency. Within laboratory trials, the results indicated that highest Pb adsorption efficiency revealed through the increasing of SiO2NPs concentrations until 120 h. In vivo trial that lasted for 8 weeks, Nile tilapia (Oreochromis niloticus) (29.78 ± 0.36 g body weight) supplemented with 0.088 mg/L Pb was divided into four experimental groups having three replicates (15 fish/replicate; 45 fish/group). The results showed that SiO2NPs supplementation through water revealed significant increase in growth and hematological parameters of O. niloticus. Moreover, enhancement of antioxidant capacity (TAC), and immune related gene expression of IL-1ß were increased in the presence of SiO2NPs compared with the groups of Pb exposure. Moreover, Pb residue level in fish muscles was noticeably decreased in the SiO2NPs treated groups. Thus, this research opens up other possibilities in the field of using SiO2NPs as a lead adsorbent for water bioremediation.

Shared decision-making aid for juvenile idiopathic arthritis: moving from informative patient education to interactive critical thinking.

OBJECTIVES: To develop and evaluate an illustrated, stand-alone, interactive evidence-based shared decision making (SDM) aid for JIA children; its ability to produce positive perceived involvement of JIA patients in their own management and its impact on their adherence to therapy, school absenteeism and treatment outcomes. METHODS: The SDM aid was developed to offer information about the disease, risks and benefits of treatment. A multidisciplinary team defined SDM criteria based on international standards (IPDAS). Eight categories emerged as highly important for SDM. Each category was supported by simple illustrations in an interactive style. At the end of each category, the child is asked to make a decision in view of the information given. Ninety-four JIA children were provided with the tool, in a randomised controlled study, in comparison to a control group of 95 JIA patients treated according to standard protocols. RESULTS: A total of 97.5% of the study children reported comprehensibility of more than 90%. The patients' adherence to therapy was significantly (p < 0.01) higher in the SDM group, whereas stopping DMARDs for intolerability was significantly higher in the control group at 12 months of treatment. There was a significant improvement in the patient-reported outcomes in the SDM group, and absence from school was significantly higher in the control group (p < 0.01). CONCLUSIONS: The developed SDM aid offered the children evidence-based information about the pros and cons of treatment options and improved their understanding of the disease and their ability to make an informed decision that is reflected on their adherence to therapy and better treatment outcomes. Key Points • This work represents the second generation of shared decision-making tools. • The developed tool adopts an interactive style and enhances critical thinking, giving the patients the facility of making their own decision regarding their management. • The work gives an example of core domain set of outcomes which can be used for shared decision-making interventions.

Facilitating patient-centered care: the development of illustrated multidimensional patient-reported outcome measures for children/adolescents with juvenile idiopathic arthritis.

OBJECTIVES: To assess the validity, reliability, comprehensibility, and responsiveness to change of an illustrated child/parent multidimensional patient-reported outcome measures (PROMs) questionnaire which can assess construct outcome measures of children with juvenile inflammatory arthritis. METHODS: A total of 122 children with juvenile idiopathic arthritis were included in this work in a multicenter study. The questionnaire included seven categories: (1) functional ability; (2) health-related quality of life; (3) disease activity measures: pain, global assessment, fatigue, and morning stiffness; (4) self-reported joint tenderness; (5) current medication, side effects, and adherence to therapy; (6) comorbidities; and (7) patient motivation. All the items were supported by illustrations to provide children with a visual impression of what was meant by the questions. The questionnaire has parent and patient versions. The disease activity status was assessed using JADAS-27. RESULTS: The questionnaire was reliable as demonstrated by a high-standardized alpha (0.890-0.978). The questionnaire items correlated significantly (p < 0.01) with clinical parameters of disease activity. The patient-reported tender joints correlated significantly with the physician's scores (0.842). Changes in functional disability, quality of life, and the motivation score showed significant variation (p < 0.01) with disease activity status in response to therapy. The illustrated PROMs questionnaire showed also a high degree of comprehensibility (9.6). CONCLUSIONS: Integrating PROMs into standard clinical practice is feasible and applicable. The illustrated questionnaire was valid and reliable. It provides an informative, quantitative measure for the disease activity score set data, and in the meantime, facilitates the assessment of the children's adherence to therapy, comorbidities, and motivation on an individual basis.

Toward electronic health recording: evaluation of electronic patient reported outcome measures (e-PROMs) system for remote monitoring of early systemic lupus patients.

The study aimed to assess the value of evaluation of electronic patient reported outcome measures (e-PROMs) in the assessment and management of SLE disease activity flares, its association with adherence to therapy as well as organ damage. A randomized, controlled crossover study was carried out over a 24-month duration. One hundred forty-seven SLE patients meeting the revised American College of Rheumatology (ACR) criteria were enrolled. Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) was used to assess disease activity, whereas organ damage was scored using the Systemic Lupus International Collaborating Clinics (SLICC)/ACR Damage Index. In the first 12 months, the patients were assessed every 3 months. At 12 months, the patients were randomized into a cohort of 73 patients who continued their care in the same style and 74 patients who completed an online e-PROMs questionnaire on monthly basis for another 12-month period. The data captured were then retrospectively analyzed at the end of the 24-month study period. At the end of the first year of the study, the mean SLEDAI and SDI scores were 8.72 (6.1) and 1.9 (2.2). At the end of the second year, the mean SLEDAI and SDI scores in the e-PROMs cohort were 3.1 (2.6) and 1.2 (1.3), whereas in the control group, the scores were 7.63 (6.7) and 1.8 (2.3), respectively (p < 0.01). Adjusting for possible confounding variables, the number of flares, regardless of their severity, was associated with damage accrual (OR 2.03, 95% CI 1.34 to 2.83, p < 0.001). Adherence to therapy was significantly (p < 0.1) higher in the e-PROMs group. e-PROMs was equivalent to PROMs paper format and has a potential disease-modifying effect as it facilitated close monitoring of disease activity with an option of management escalation whenever indicated.

Optimizing therapy in inflammatory arthritis: prediction of relapse after tapering or stopping treatment for rheumatoid arthritis patients achieving clinical and radiological remission.

This study aims to assess clinical, lab/immunological or imaging (joint ultrasonography) markers able to predict disease relapse in RA patients in sustained remission when tapering or stopping their treatment. One hundred fifty-seven RA patients in clinical remission (DAS-28 <2.6 for >6 months), receiving treatment with sDMARDs and bDMARD therapy, were randomly allocated into any of five groups: Group 1: continue full dose DMARDs and taper biologic therapy by 50 % (31 patients); Group 2: taper both DMARDs and biologic therapy dose by 50 % (32 patients); Group 3: taper DMARDs by 50 % and stop biologic therapy (31 patients); Group 4: stop both DMARDs and biologic therapy (31 patients); Group 5: continue medications without change (31 patients). Forty joints were assessed ultrasonographically (DAS-28 joints + ankles + metatarsophalangeal joints) and prospectively monitored for 12 months. The primary endpoint was sustained remission for 12 months. Patients were considered as having a relapse when the DAS-28 score was >3.2 and anti-rheumatic treatment was escalated. The frequency of relapse was 41.9 % in Group 1, 59.3 % in Group 2, 67.7 % in Group 3, 77.4 % in Group 4 and 6.5 % in Group 5. Relapse rates were significantly higher in patients whose ultrasound scores raised within 3 months of stopping their medications (P < 0.001 for both GS and PD scores). Cox regression identified ACPA positivity (at baseline) and progression of functional disability (at 2 months) as predictors for relapse. Tapering therapy is feasible in RA patients. Tailored dynamic approach is advised. Joint ultrasonographic assessment, ACPA positivity and worsening functional disability predicted relapse within a short term after discontinuation of the treatment. RA patients whose DAS-28 score was <2 were more likely to remain in remission.

Compliance with haemodialysis practice guidelines in Egypt.

Evidence- and consensus-based clinical practice guidelines for haemodialysis have recently been developed in Egypt. This study aimed to measure compliance with the guidelines in a sample of 16 government hospitals in Cairo and Giza governorates. Each haemodialysis unit was visited to assess the haemodialysis unit and patient care practices for all patients under dialysis at the time of the visit. The mean percentage compliance with haemodialysis guidelines among all study hospitals was 59.3% (SD 11.2%) overall. Within the 5 separate domains, compliance was: 58.8% (SD 12.4%) for personnel, 68.5% (SD 16.0%) for patient care practices, 61.3% (SD 15.4%) for infection prevention and control, 51.5% (SD 18.2%) for the facility and 56.5% (SD 7.1%) for documentation/ records. There were no statistically significant differences between Cairo and Giza governorates except for facility measures which were slightly better in Giza. Overall, compliance with the developed practice guidelines for haemodialysis in Egypt was not satisfactory and was not uniform across facilities.

Assessment of the utility of visual feedback in the treatment of early rheumatoid arthritis patients: a pilot study.

Earlier studies revealed that visual feedback has contributed in the management of neuromuscular as well as psychiatric disorders; however, it has not yet been applied in rheumatology. Visual feedback is a relatively new tool that enables the patient to visualize as well as monitor a real-time change of their disease activity parameters as well as the patient's reported outcome measures. Integrating electronic data recording in the standard rheumatology clinical practice made visual feedback possible. To evaluate the feasibility of using the visual feedback in patients with early inflammatory arthritis (EA) and how ubiquitous computing technology can improve the patients' compliance and adherence to therapy, this was a double-blind randomized controlled study, which included 111 patients diagnosed to have EA according to the new ACR/EULAR criteria. All patients received disease-modifying antirheumatic drugs (DMARDs) therapy and monitored regularly over the period of 1 year. By the 6th month of treatment, the patients were randomly allocated to an active group (55 patients) to whom the visual feedback (visualization of charts showing the progression of disease activity parameters) was added to their management protocol, and a control group (56 patients) who continued their standard management protocols. The patients were monitored for another 6-months period. All the patient's disease activity parameters, patient reported outcome measures (PROMs), medications, scores of falls, and cardiovascular risks were recorded electronically. Primary outcome was the change in the patients' adherence to their medications, disease activity score (DAS-28), and PROMs: pain score, patient global assessment, functional disability, and quality of life. Secondary outcome was the answers to a questionnaire completed by every patient in both the active group and control group (using Visual Analogue Scale) by the end of 1 year of management, to rate from the patient's perspective the impact of the management protocol, whether using the standard or visual feedback approach, on them and their disease. The visual feedback provided a significant greater reduction in disease activity parameters as well as improvement of the patients' adherence to antirheumatic therapy (P < 0.01). Also stopping the DMARDs therapy because of intolerance was significantly less in the active group. Concerns about the future was significantly less in the active group whereas inability to coup with daily life and disease stress were significantly more among the control group. The improvement of disease activity parameters was associated with improvement in functional disability and quality of life scores. Mean changes in disease parameters showed no significant differences at 3-6 months of therapy but differences were statistically significant at 12-months follow-up (P < 0.01). Medication compliance was significantly correlated with changes in all measured disease parameters. By recording and monitoring disease activity parameters electronically and incorporating the visual feedback approach into clinical practice, a new experience can be created. Visual feedback enabled the patients to see how they are doing regarding their disease activity and helps to optimize their adherence to their treatment. Visual feedback had a positive and significant impact on the disease activity control.

Sexual dysfunction in rheumatoid arthritis patients: arthritis and beyond.

Rheumatoid arthritis treatment has been shown to improve quality of life. There is little data regarding the impact of the disease and treatments on sexual function. The aim of this study was to describe the results of an assessment of sexual activity/sexual satisfaction of rheumatoid arthritis patients, identify the sexual dysfunction features, and assess their association with disease activity/disease activity parameters and other systemic risk factors/comorbidities. Consecutive rheumatoid arthritis patients attending the outpatient rheumatology clinic completed the multidimensional patient-reported outcome measures questionnaire. There are three questions screening for sexual dysfunction: patients who ticked any of the boxes were further assessed. Men completed the Sexual Health Inventory for Men; whereas women completed the Female Sexual Function Index. All patients underwent clinical assessment of disease activity parameters and cardiovascular risk. Among 231 rheumatoid arthritis patients included in this study, 49/91 (53.8%) men and 64/140 (45.7%) women reported sexual dysfunction. Among men, erectile dysfunction significantly correlated (p < 0.01) with pain score, cardiovascular disease, age, disease activity, fatigue score, intramuscular steroid injection, and tender joint count. Among women, sexual dysfunction was significantly correlated (p < 0.01) with occurrence of secondary Sjogren's syndrome, pain score, cardiovascular disease, hip joint involvement, disease activity, and tender joint count. Sexual dysfunction is common among rheumatoid arthritis patients. Erectile dysfunction in men, and problems with orgasm, arousal, and satisfaction in women, were the most prevalent manifestations. The significant correlation of sexual dysfunction with CVD may help to identify patients at high risk of cardiovascular disorders.

Incorporating patient reported outcome measures in clinical practice: development and validation of a questionnaire for inflammatory arthritis.

BACKGROUND: Rheumatology is embarking on a fundamental redesign of rheumatic disease care. It has become mandatory not only to recognise disease activity core set data, but also the risks for other co-morbidities associated with inflammatory arthritis. Measurement of patient reported outcomes have become critical in both standard clinical practice and long term observational studies. OBJECTIVES: To assess validity, reliability and responsiveness to change of a patient self-reported questionnaire which can assess construct outcome measures of patients with inflammatory arthritis. METHODS: Four hundred and sixty-two patients with inflammatory arthritis were included in this work. The questionnaire was developed by integrating information obtained from patients suffering from inflammatory arthritis based on the Rasch model for ordered response options. The questionnaire includes assessment for functional disability, quality of life, VAS for joint pain, global status, fatigue, duration of morning stiffness, review of the systems, falls and cardiovascular risks, self-helplessness, as well as self reported joint pain. RESULTS: The questionnaire was reliable as demonstrated by a high-standardised alpha (0.891-0.992). The questionnaire items correlated significantly (p<0.01) with clinical parameters of disease activity. RA patient reported tender joints correlated significantly with the physician's scores (0.842). Changes in functional disability, quality of life as well as self-helplessness scores showed significant (p<0.01) variation with disease activity status. The PROMs questionnaire also showed a high degree of comprehensibility.(9.4). CONCLUSIONS: Integrating patient reported outcome measures into standard clinical practice is feasible and applicable. This version of a multidimensional questionnaire was found to be valid and reliable. It provides informative quantitative measures for the disease activity core set data, and in the mean time, facilitates assessing the patients' health related quality of life measure, cardiovascular and falls risks on an individual basis.

Concerns, perceived impacts and preparedness of health care workers in a referral hospital in Egypt in facing influenza (H1N1) epidemic.

OBJECTIVE: In Egypt, influenza A (H1N1) cases have been detected and deaths have been reported. The aim of this study was to investigate concerns, perceived impacts and preparedness of Physicians and Nurses of Chest Specialty Hospital in Cairo (Egypt) concerning Influenza A (H1N1). METHODS: A questionnaire was applied to a total of 72 Physicians and 41 Nurses from Chest Specialty Hospital in Cairo (Egypt). RESULTS: More than half of physicians (55.6%) were men, while most of nurses (92.7%) were women. The mean age in years of physicians was 36.6 +/- 11.3 compared to 26.5 +/- 8 in nurses. Physicians feel that they are at greater risk by their job to the pandemic 100% compared to 87.6% among nurses and the difference is highly significant. More than one third of the studied physicians reported that they are not ready to face H1N1 pandemic. Residents feel less ready to face the danger of lnfluenza A(H1N1) compared with Consultants and Specialists/Assistant Specialists, with no statistical significant difference. In concordance, Residents reported less Personal Protective Equipment training compared with Consultants and Specialists/Assistant Specialists, with no statistical significant difference. All Consultants received Seasonal Influenza Vaccine compared with Specialists/Assistant Specialists (68.2%) and Residents (44.7%). CONCLUSION: Higher work related and non work related stress was found among physicians compared to nurses, which reflects the demand of more information and training courses for physicians about the pandemic nature and its consequences, complications, and methods infection prevention.

Development of practice guidelines for hemodialysis in Egypt.

Although hemodialysis is the main modaility of treatment of end-stage renal disease, no practice guidelines are available in Egypt. Applying international guidelines for hemodialysis would not be suitable or feasible, because of different health system and lack of resources. The aim of this project was the development of evidence- and consensus-based clinical practice guidelines for hemodialysis in Egypt. The Egyptian guidelines were adopted from the standards developed by The College of Physicians and Surgeons of Alberta (Canada), The National Kidney Foundation (USA), The Clinical Standards Board for Scotland (Scotland), and The College of Physicians and Surgeons of Ontario (Canada). In addition, the guidelines published in Oxford Handbook of Dialysis were reviewed. Thereafter, a panel of Egyptian experts in the field of nephrology and hemodialysis was selected and invited to participate in this project. The Delphi technique was applied to build up the consensus among the experts on the formulated guidelines. The final version of the Egyptian Hemodialysis Practice Guidelines included five main sections; personnel, patient care practices, infection prevention and control, facility, and documentation/records. A consensus on practice guidelines for hemodialysis has been successfully produced and is supported by levels of evidence. The 12 Egyptian experts who participated in the Delphi technique and the reviewers assured the completeness and acceptability of the developed practice guidelines. Also, including experts from the university hospitals together with the Directorates of Cairo and Giza Health Affairs of the Egyptian Ministry of Health (MOH) avoided conflicts between clinical recommendations and feasible application in the MOH hemodialysis facilities.

Prevalence and risk factors for hearing disorders in secondary school students in Ismailia, Egypt.

This study estimated the prevalence of hearing disorders and associated risk factors in a 10% sample of all secondary-school students in Ismailia city, Egypt. All participants were given a questionnaire and Weber and Rinne tests for hearing disabilities. Among 2633 students, the prevalence of hearing loss was 22.2%, mostly sensorineural hearing loss. More students at technical schools had mixed sensorineural and conductive hearing loss (46.2%) than students at general (28.6%) or commercial (25.3%) schools. Multivariate logistic regression analysis identified the number of attacks of otitis media, history of ear disease treatment, history of admission to fever hospital and history of ear surgery as independent risk factors for sensorineural hearing loss.

Prevalence and socioeconomic associations of asthma and allergic rhinitis in northern [corrected] Africa.

The aims of the current study were to ascertain the prevalence of asthma and allergic rhinoconjunctivitis symptoms in Cairo, Egypt (northern Africa), and to elucidate the socioeconomic factors associated with symptom prevalence and severity. A translated and adapted version of the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire was distributed to a sample of 2,645 11-15-yr-olds in state and fee-paying schools in Cairo. The overall prevalences of wheeze ever, wheeze during the last year and physician-diagnosed asthma were 26.5% (697 out of 2,631), 14.7% (379 out of 2,570) and 9.4% (246 out of 2,609), respectively. The prevalence of rhinoconjunctivitis was 15.3% (399 out of 2,616). Asthma symptoms were independently associated with attendance at a state school, parental asthma, age, history of rhinitis and owning a pet cat. Rhinoconjunctivitis was independently associated with attendance at a state school, father's education, parental history of asthma, asthma symptoms and owning a pet cat. In spite of a higher prevalence of severe asthma symptoms in state schools prevalence of physician diagnosis of asthma was the same in both school types, suggesting inequalities in access to healthcare. In conclusion, the prevalence of physician-diagnosed asthma in Cairo was 9.4%, while the prevalence of rhinoconjunctivitis was 15.3%. There is a higher prevalence and increased severity of asthma symptoms in children of lower socioeconomic groups, as defined by state school attendance in Cairo.

Diagnosis of early arthritis: outcomes of a nurse-led clinic.

Recent data suggest that early treatment of inflammatory arthritis can improve patient outcomes. While rheumatologists recognized this need for early evaluation and treatment, the current load on the rheumatology service nationwide may limit the capacity for timely evaluation. The authors developed a protocol to be applied through a specialized early arthritis clinic that is able to discriminate between different categories of early arthritis, to shortening the time taken to reach the correct diagnosis and provide the appropriate management. A total of 108 patients have been reviewed in the early arthritis clinic over 12 months. It took 3 weeks for the patients to be fully assessed in the rheumatology clinic instead of 16 weeks. Completing the clinic proforma helped the assessor to cover all causes of arthritis/arthralgia. Disease-modifying antirheumatic drug (DMARD) therapy was initiated within a few weeks (2 to 5 weeks) once diagnosis was confirmed, instead of 8 to 10 months previously. This early arthritis clinic model helped to shorten the referral lag time (duration between symptoms onset and first rheumatologist assessment) as well as lag time to DMARD therapy (duration between symptom onset and the institution of DMARD therapy).

Cross cultural adaptation and validation of the Arabic version of the Childhood Health Assessment Questionnaire for measuring functional status in children with juvenile idiopathic arthritis.

OBJECTIVE: To cross culturally adapt the American-English version of the Childhood Health Assessment Questionnaire (CHAQ) and to evaluate the validity and reliability of the modified translated version on children with juvenile idiopathic arthritis (JIA). METHODS: A cohort of 62 children suffering from JIA (32 Egyptian, 30 Saudi Arabian) were recruited and asked to participate in the study. Two questions had been changed to suit the Arabic culture and to tackle some aspects that are more typical of the Arabic culture. After modification, translation and back translation of the questionnaire, it was administered to the selected patients as well as their parents and tested for internal consistency, reliability and construct validity by correlating the yield of the questionnaire with other disease activity parameters. The questionnaire was administered again after a one-week interval for evaluation of the reliability of this test. The modified questions were tested for their loyalty to the principal component and their correlation with that of the other unchanged items was compared. RESULTS: CHAQ proved to be valid in clinically discriminating between healthy subjects and patients with different patterns of JIA. Test-retest showed strong reliability with a high percentage of agreement and high kappa values. Internal consistency showed a high value for the standardized Cronbach's alpha (0.951), and this value did not show any significant change when any one of the items was eliminated. The modified questionnaire showed a strong and significant validity when its results were correlated with disease activity parameters. CONCLUSION: The Arabic CHAQ is a reliable and valid instrument that can be administered to Arabic children suffering from JIA and to their parents, to evaluate the patients' functional disability. Its measurement properties were comparable to versions in other languages.

Some epidemiological aspects of patients with end stage renal diseases.

This study was carried out to describe End Stage Renal Disease (ESRD) among Egyptian patients and to identify the possible risk factors of their disease. A case-control study was conducted with 2 control groups (patient or hospital control group and normal community control group) compared with ESRD cases on haemodialysis. The study revealed that hypertension, followed by obstructive uropathy, are the leading causes of ESRD. Conducting the multiple logistic regression analysis, the following factors were found to act independently as risk factors for ESRD, in that order of importance: past history of hypertension, family history of renal failure, past history of renal pain, smoking, urban origin of birth, past history of renal or urinary stones, past history of schistosomiasis, the presence of a near-by residential factory and past history of frequent hospitalization. A quality of life score has been invented. Women experienced a bad quality of life in relation to men and the score correlated positively with age. A number of recommendations have been generated.
