    Interstitial lung disease (ILD) is one of the major causes of death in systemic scleroderma (SSD). Treatment of these patients remains difficult and controversial. Mycophenolate mofetil (MPM) has been in vitro shown to inhibit overproduction of type I collagen and hence may be effective against SSD. Objective: to study the efficiency and safety of MPM therapy in patients with SSD and clinically relevant ILD in an open-label prospective study. Subjects and methods. Ten patients with SSD (7 and 3 with its diffuse and limited forms, respectively) and ILD were given MPM in combination with glucocorticoids (mean daily dose was 10+4 mg). The mean MPM therapy duration was 11.4+1.3 months. The Rodnan total skin thickness score, flexion index, forced vital capacity (FVC), diffusing capacity of the lung for carbon monoxide (DLCO), and European Scleroderma Study Group (EScSG) activity index were estimated and a 6-minute walk test (6MWT) was carried out before and after MPM therapy. Results. After therapy, the whole group showed a significant reduction in skin scores from 12.9+9.8 to 5.6+3.2 (p=0.036) and EScSG from 3.9+1.4 to 2.25+1.03 (p=0.015) and an increase in exercise tolerance from 446+155 to 535+78 m (p=0.03) as evidenced by 6MWT. The degree of flexion contractures decreased from 15+21 to 3.7+11.3 mm (p>0.05). FVC (77.8+18.7% versus 73.8+11.3%) and DLCO (45+14.4% versus 42+16.4%) were significantly unchanged. A 10% or more clinically significant fall was noted in FVC and DLCO in 3 and 1 patients, respectively. In the remaining patients, the lung functional test results remained stable. MPM tolerability was satisfactory. All the patients completed their course of treatment. Conclusion. Stabilization of lung function with higher exercise tolerance and significantly reduced skin density allow therapy with MPM in combination with low-dose glucocorticoids to be regarded as an effective and well-tolerated treatment in patients with ILD in the presence of SS

    Objective: to assess the frequency of a reduction in bone mineral density (BMD) and its association with traditional risk factors and clinical parameters in patients with systemic scleroderma (SSD).Patients and methods. The investigation included 330people: 190 patients (median age 55 [41; 61.5] years) with SSD and 140 control individuals (median age 57 [40.5; 66] years without a history of inflammatory rheumatic diseases. The patients were interviewed using a uniform questionnaire; dual-energy X-ray absorptiometry was used to measure BMD in the lumbar spine (Li-iv), femoral neck (FN), entire proximal femur (PF), and distal third of the forearm (DTF). The concentration of 25(OH)D was measured in 155 examinees.Results and discussion. Decreased BMD was found in 69% of patients with SSD and in 58% of controls (p=0.0392), including osteoporosis (OP) in 38 and 31% of cases, respectively. BMD in the Li-iv and FN was significantly lower in the women with SSD than in the control exam-nees, regardless of age. There was a direct correlation between BMD and body mass index (BMi) and an inverse correlation between BMD and the duration of menopause, that of the disease, and cumulative dose of glucocorticoids (GCs). Among the analyzed clinical factors, there was an inverse correlation between Li-iv BMD and erythrocyte sedimentation rate (ESR), between BMD in both femoral areas (FN and PF) and C-reactive protein (CRP). The mean concentration of 25(OH)D was 19.83+11.06 ng/mL in the patients with SSD and 23.29+8.61 ng/mL in the controls; normal vitamin D levels were detected in 9% of the patients with SSD and 24% of the controls (p<0.05).Conclusion. Low BMD was found in 69% of patients with SSD, including in those with OP (38%). Most (91%) patients had vitamin D deficiency. BMD correlated with traditional risk factors: positively with BMi and negatively with age and menopause duration. The clinical factors were found to be association with disease duration and cumulative GC dose.ЦСль исслСдования β€” ΠΎΡ†Π΅Π½ΠΊΠ° частоты сниТСния ΠΌΠΈΠ½Π΅Ρ€Π°Π»ΡŒΠ½ΠΎΠΉ плотности кости (МПК) ΠΈ Π΅Π΅ взаимосвязи с Ρ‚Ρ€Π°Π΄ΠΈΡ†ΠΈΠΎΠ½Π½Ρ‹ΠΌΠΈ Ρ„Π°ΠΊΡ‚ΠΎΡ€Π°ΠΌΠΈ риска ΠΈ клиничСскими ΠΏΠ°Ρ€Π°ΠΌΠ΅Ρ‚Ρ€Π°ΠΌΠΈ Ρƒ ΠΏΠ°Ρ†ΠΈΠ΅Π½Ρ‚ΠΎΠ² с систСмной склСродСрмиСй (Π‘Π‘Π”).ΠŸΠ°Ρ†ΠΈΠ΅Π½Ρ‚Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.

    The objective of this 5year prospective study was to investigate a clinical role of isolated decrease of DLCO in patients with systemic sclerosis (SS)Β without pulmonary arterial hypertension (PAH).Methods. We selected 48 out of 142 patients with SS: 35 (73%) with limited SS and 13 (27%) withΒ diffuse SS. The average length of the disease was 12.9 Β± 7.9 years. Inclusion criteria were DLCO < 80% pred., forced vital capacity (FVC) β‰₯ 80%Β pred. and systolic pulmonary artery pressure (PAP) ≀ 35 mm Hg according to echocardiographic examination (echoCG). High resolution computed tomography (HRCT), spirometry, DLCO measurement, and echoCG were obtained at baseline and after 4.7 Β± 1 year of follow up. All patientsΒ were treated with standard therapy.Results. CT signs of interstitial lung disease (ILD) were found in 43 (89.6%) patients at baseline and newly developed in 3 other patients during the followup. During the followup, lung CT improved in 5 (10.4%) patients and progressed in 15 (31.3%) patients.Β Over 5 years, FVC did not change significantly (97.6 Β± 10.7% and 100.8 Β± 18.9%; Ρ€ = 0.15), while DLCO significantly decreased both in limitedΒ and diffuse SS groups (59.8 Β± 13.5% and 56.3 Β± 12%; Ρ€ = 0.006). Mean PAP values remained within normal range in majority of patients. ClinicallyΒ significant FVC reduction (β‰₯ 10%) was found in 5 patients; of them, CT signs of ILD at baseline were seen in 3 patients and newly developed during the followup in 2 others. Clinically significant DLCO reduction (β‰₯ 10%) was documented in 11 (23%) patients, all had CT signs of ILD at baseline, although CT progression during the followup was noted only in six of them. Contemporary deterioration in FVC, DLCO and CT was found in 3 patients.Conclusion. Clinical course of ILD in SS patients with isolated DLCO reduction and without PAH was relatively benign, with respiratoryΒ volumes being preserved within normal range for long time. Comparison of radiological and functional changes in a prospective study has suggested that DLCO is a more sensitive tool to determine ILD progression compared to HRCT. Regular DLCO measurements could be used as a reliable toolΒ for monitoring of ILD associated with SS.Π˜Π½Ρ‚Π΅Ρ€ΡΡ‚ΠΈΡ†ΠΈΠ°Π»ΡŒΠ½ΠΎΠ΅ ΠΏΠΎΡ€Π°ΠΆΠ΅Π½ΠΈΠ΅ Π»Π΅Π³ΠΊΠΈΡ… (Π˜ΠŸΠ›) ΠΏΡ€ΠΈ систСмной склСродСрмии (Π‘Π‘Π”), ΠΊΠ°ΠΊ ΠΏΡ€Π°Π²ΠΈΠ»ΠΎ, сопровоТдаСтся Ρ€Π΅ΡΡ‚Ρ€ΠΈΠΊΡ‚ΠΈΠ²Π½Ρ‹ΠΌΠΈΒ Π½Π°Ρ€ΡƒΡˆΠ΅Π½ΠΈΡΠΌΠΈ Π»Π΅Π³ΠΎΡ‡Π½ΠΎΠΉ Ρ„ΡƒΠ½ΠΊΡ†ΠΈΠΈ, ΠΏΡ€ΠΈ этом сниТСниС Π΄Ρ‹Ρ…Π°Ρ‚Π΅Π»ΡŒΠ½Ρ‹Ρ… объСмов ΠΈ Π΄ΠΈΡ„Ρ„ΡƒΠ·ΠΈΠΎΠ½Π½ΠΎΠΉ способности Π»Π΅Π³ΠΊΠΈΡ… (DLCO) ΠΏΡ€ΠΎΠΈΡΡ…ΠΎΠ΄ΠΈΡ‚Β ΠΏΠ°Ρ€Π°Π»Π»Π΅Π»ΡŒΠ½ΠΎ.

    Electronic properties and phase transitions in low-dimensional semiconductors

    Full text link
    We present the first review of the current state of the literature on electronic properties and phase transitions in TlX and TlMX2 (M = Ga, In; X = Se, S, Te) compounds. These chalcogenides belong to a family of the low-dimensional semiconductors possessing chain or layered structure. They are of significant interest because of their highly anisotropic properties, semi- and photoconductivity, non-linear effects in their I-V characteristics (including a region of negative differential resistance), switching and memory effects, second harmonic optical generation, relaxor behavior and potential applications for optoelectronic devices. We review the crystal structure of TlX and TlMX2 compounds, their transport properties under ambient conditions, experimental and theoretical studies of the electronic structure, transport properties and semiconductor-metal phase transitions under high pressure, and sequences of temperature-induced structural phase transitions with intermediate incommensurate states. Electronic nature of the ferroelectric phase transitions in the above-mentioned compounds, as well as relaxor behavior, nanodomains and possible occurrence of quantum dots in doped and irradiated crystals is discussed.Comment: 70 pages, 38 figure

    SYSTEMIC SCLEROSIS AND OSTEOPOROSIS

    No full text
    Systemic sclerosis is an autoimmune inflammatory disease of connective tissue with multi-syndrome clinical manifestations. Skeletal damage is considered to be one of significant contributors to the quality of life of these patients. The purpose of this review was to assess the prevalence of osteoporosis and associated fractures in systemic sclerosis. We performed a search in Medline database by the following key words: β€œsystemic sclerosis”, β€œbone mineral density” and β€œosteoporosis”. From 118 publications we selected for further analysis 18 papers which contained comparisons of bone mineral density in patients with systemic sclerosis and in control groups of healthy subjects or in patients with other rheumatic disorders. These trials showed various proportions of systemic sclerosis patients with decreased bone mineral density in the range of 32 to 77%. Osteoporosis was found in 22 to 60% women with systemic sclerosis which was significantly more frequent that in healthy age-matched women (from 8 to 23%). The rates of osteoporotic fractures in patients with systemic sclerosis, according to data given by various authors, were in the range of 2 to 38%, being higher than in healthy controls (from 2 to 10%). In the majority of publications, there was an association of osteoporosis with conventional risk factors, and in some studies there was an association of osteoporosis with clinical characteristics of systemic sclerosis. The studies were performed in relatively small patient groups and their results vary widely. Further studies are necessary to elucidate the mechanisms of osteoporosis and improve its treatment and prevention in patients with systemic sclerosis
