Social consequences of a disease constitute limitations in performing roles relating to working life as well as family and social life caused by the disease, mainly chronic. The aim of the study was to analyze the social consequences of rheumatic diseases in the aspect of disability pensions with respect to incapacity for work and quality of life. The occurrence of rheumatic diseases is related not only to increased risk of different types of organic changes, but above all disability. In Europe almost 50% of persons suffering from diseases of the musculoskeletal system who are currently unemployed were breadwinners. Nearly 60% of them received legal disability status. The loss of work ability is, among other things, the consequence of progressive disability. In Europe 40% of persons suffering from rheumatoid arthritis (RA) had to stop working due to the disease. Most of the persons diagnosed with RA were of working age. It results in the decrease in the quality of life as well as economic difficulties (decreased incomes and increased disease-related costs). In Poland the results of the analysis of the Social Insurance Institution (ZUS) of first-time disability recognition issued for the purpose of disability pensions in 2014 showed that the incapacity for work was caused by diseases relating to general health condition (65.5%). Diseases of the musculoskeletal system were the cause of partial inability to work of 21.6% of persons who received a disability pension for the first time (as many as 5,349 certificates were issued). Early diagnosis and implementation of effective treatment are the necessary conditions for a patient to sustain activity, both professional and social, which is of crucial importance to reduce the negative effects of the disease.

According to the data published in The Lancet, in 2010 musculoskeletal disorders were the cause of nearly 166 million years lived with disability (YLDs), with neck and low back pain accounting for 69.9% of the total. In Poland, in 2014 low back pain was self-reported by 28.4% of women and 21.2% of men aged 15 years and over, neck pain by 21% of women and 13% of men, and middle back pain by 19% of women and 12.9% of men. In 2015, nearly 33 million man-days were lost due to spine disorders, and nearly 2.7 million medical certificates were issued for back pain (15% of the total). With the current demographic changes (population ageing) and lifestyle-related factors increasing the potential for back problems, the demand for a wide range of medical services to treat disorders of the spine and their symptoms may be expected to increase substantially over the coming years.

The aim of the report was to determine the effects of soy isoflavones on lumbar spine, femoral neck, and total hip bone mineral density (BMD) in menopausal women. MEDLINE (PubMed), EMBASE, and Cochrane Library databases were searched for articles published in English during 1995–2019. Studies were identified and reviewed for inclusion and exclusion eligibility. Weighted mean differences (WMD) were calculated for each study and were pooled by using the random effects model. Eighteen randomized controlled trials were selected for meta-analysis. Different types of soy phytoestrogens, i.e., genistein extracts, soy isoflavones extracts, soy protein isolate, and foods containing diverse amounts of isoflavones were used in the studies. The analysis showed that daily intake of 106 (range, 40–300) mg of isoflavones for 6–24 months moderately but statistically significantly positively affects BMD, compared with controls: lumbar spine WMD = 1.63 (95% CI: 0.51 to 2.75)%, p = 0004; femoral neck WMD = 1.87 (95% CI: 0.14 to 3.60)%, p = 0.034; and total hip WMD = 0.39 (95% CI: 0.08 to 0.69)%, p = 0.013. Subgroups analyses indicated that the varying effects of isoflavones on BMD across the trials might be associated with intervention duration, racial diversity (Caucasian, Asian), time after menopause, form of supplements (especially genistein), and dose of isoflavones. Our review and meta-analysis suggest that soy isoflavones are effective in slowing down bone loss after menopause.

Objective: The objective of this study was to determine the length of delay in diagnosis of inflammatory rheumatic diseases, and to indicate the main factors responsible for such delays. Material and methods: A retrospective multi-centre questionnaire survey carried out among 197 patients with diagnosed inflammatory rheumatic diseases or undergoing the diagnostic process. Results: The most common early symptoms of inflammatory rheumatic disease included joint pain (94%), joint swelling (78%), morning joint stiffness (77%), fatigue (76%), and sleep disturbed by joint pain (74%). When asked about the reasons for seeking medical help, most patients indicated intensification of the symptoms (89%) and the fact that the symptoms made them unable to perform daily activities or work (86%). Limited access to specialists (70%) and the conviction that the symptoms will resolve spontaneously (57%) had the biggest impact on delaying a visit to a doctor. Before visiting a rheumatologist, the patients consulted their symptoms with their general practitioners (GPs, 95%), orthopaedicians (43%), and neurologists (29%). Almost half of the patients (48%) consulted their symptoms with at least 2 non-rheumatologists, whereas as many as 21% of patients visited 4 or more specialists. After the onset of symptoms of rheumatic disease, 28% of patients delayed seeing any doctor for 4 months or longer. 36% of patients waited 4 months or longer for a referral to a rheumatologist. The great majority of the patients (85%) made an appointment with a rheumatologist within a month of receiving a referral. 25% of patients waited 4 months or longer to see a rheumatologist. Conclusions: Diagnostic delays result from both the level of patients’ awareness (ignoring early symptoms) and improper functioning of the health care system. In the case of the health care system, the source of delays is not only “queues to rheumatologists”, but also referring patients to non-rheumatologists.

It is estimated that every third person living in Europe suffers from allergic diseases. Allergies are a growing health problem in Poland where 40% of the population have allergy symptoms, including 12% afflicted with asthma. The actual cost of allergic diseases is difficult to estimate due to...

Objectives: The aim of this study was to assess the correlation between symptoms of depression and the course and clinical picture of rheumatoid arthritis (RA).Material and methods: 120 patients with RA were included in the study: 104 (87%) female patients and 16 (13%) male patients. All studied patients completed the following questionnaires: Beck Depression Inventory (BDI), Ford Insomnia Response to Stress Test (FIRST), Athens Insomnia Scale (AIS) and Health Assessment Questionnaire (HAQ). The serum levels of IL-1b, TNF-, and IL-6 were measured using standard ELISA assays at the time of the first questionnaire assessment.Results: Symptoms of depression were found in 91 patients (76%), including 79 (87%) women and 12 (13%) men. There were no significant differences between the prevalence of depression in women and men (p = 0.93). Symptoms of depression occurred more often in patients who were professionally inactive, compared with the professionally active patients (p = 0.04). Significant correlations was demonstrated between the value of BDI and the patient’s pain assessed by the visual analogue scale (VAS) value (r = 0.36), the disease activity assessed by the patient and the physician evaluated in millimetres on the VAS scale (r = 0.38 and r = 0.30, respectively), the number of painful and swollen joints (r = 0.22 and r = 0.26, respectively), DAS28 (r = 0.31) as well as the Health Assessment Questionnaire (HAQ) value (r = 0.46). Longer duration of the disease was observed in patients with symptoms of depression (p = 0.02). Also a significant difference in the assessment of BDI between patients treated with biological drugs and those receiving no such treatment was observed (p = 0.042).Conclusions: Professional inactivity and longer disease duration are important factors influencing symptoms of depression in patients with RA. Higher values of HAQ increase the probability of the occurrence of depression symptoms. The use of biological drugs that reduce the level of proinflammatory cytokines may have a positive effect on reducing the severity of depressive symptoms.
