They have got the blues: patient’s mood- and disease activity-related psychological burden of rheumatoid arthritis on caregivers

Objective: Rheumatoid arthritis (RA), as a long-lasting disease, not only affects the musculoskeletal health but also deteriorates the psychological well-being of the patient. What about their caregivers? There exist a limited number of studies on this issue. The objectives of the present study were (i) to evaluate the psychological health among caregivers of RA patients and (ii) to determine the confounding factors playing role on their psychological status.

Methods: Fifty-three RA patients and their caregivers were included in this cross-sectional study. Disease activity was assessed by using the disease activity score 28 based on C-reactive protein (DAS28-CRP) and rheumatoid arthritis disease activity index-5 (RADAI-5), while disability was evaluated by disability of the arm, shoulder, and hand (DASH) questionnaire. Psychological status was tested by Beck's depression and anxiety inventories (BDI and BAI).

Results: A total of 53 patients with RA were included in the study. Caregivers' depression score was weakly correlated with disease activity variables including DAS28-CRP, RADAI and DASH scores (rs?=?.304, rs?=?.392 and rs?=?.301, respectively); and moderately correlated with patients' depression score and caregivers' comorbidity (rs?=?.407 and rs?=?.451, respectively).

Conclusions: The psychological impact of RA on caregivers appears to be associated with patients’ mood, disease activity and upper extremity functionality.     

Acetabular dysplasia may be related to global joint hyperlaxity

Purpose

Some patients with shoulder laxity complain of coxalgia without a history of trauma. We hypothesised that patients who have recurrent shoulder instability accompanied with generalised joint hyperlaxity tend to have acetabular dysplasia.

Methods

Pelvic radiographs of 26 young patients with hyperlaxity who had shoulder instability complaints without any history of hip joint trauma were evaluated by measuring their centre-edge angle (CEA) and acetabular angle (AA). In addition, Beighton generalised joint laxity tests were performed. All of the patients had shoulder pain and instability accompanied with hyperlaxity. We performed magnetic resonance imaging examination to show SLAP-Bankart lesions and pelvis anteroposterior X-rays to detect acetabular dysplasia.

Results

The average age of the study group was 26?±?8.03 years (13-39). Six patients were female and 20 were male. When CEA (<22.6 degrees) was used as a criterion for acetabular dysplasia, the dysplasia rate of our patient group was 3.84 % for the right hip, 3.84 % for the left hip and 3.84 % overall. When AA (>42.2 degrees) was used as the dysplasia criterion, the dysplasia rate of patient group was 30.76 % for the right hip, 57.69 % for the left hip and 57.69 % overall.

Conclusions

CEA values were significantly lower (p?=?0.009) and AA values were significantly higher (p?<?0.001) in our study group than the previously-reported average values of the Turkish population. We think that acetabular dysplasia is more frequent in patients with hyperlaxity; further studies are needed to test this idea.

     

Neuropathic pain: is it an underestimated symptom in systemic sclerosis?

Pain is one of the most common symptoms in systemic sclerosis (SSc) patients, yet not considered in the assessment of disease severity. This study aimed to investigate the frequency of neuropathic pain (NP) and to evaluate its interference with the quality of life (QoL) in SSc patients. Diffuse and Limited SSc patients diagnosed by American College of Rheumatology 2013 criteria were included in the study. Pain was evaluated with Visual Analogue Scale (VAS); presence of NP was screened with The Leeds Assessment of Neuropathic Symptoms and Signs (LANNS) questionnaire; disease activity was evaluated with modified Medsger Severity Scale (MSS) and QoL with short-form 36 (SF-36). One hundred twenty patients were included in the study (mean age 53.64?±?11.44 years, female/male 83.3–16.7%). Total pain frequency was found 69.2% and NP was 35.9% in the entire patient group. Pain was most frequently seen in wrist-hand (50.6%) and ankle-foot (43.4%) regions; albeit, NP rates were highest in face (94.4%), lower leg (87.5%), and hip-thigh (78.6%) regions. SF-36 scores were significantly lower in patients with NP than the patients without NP (P?<?0.05). The most associated factors with NP were MSS score for muscle involvement and drug consumption of the patient. According to our results, high frequency of NP is seen in SSc patients, and NP is associated with low QoL. Differential diagnosis of NP is important to consider right treatment options and accurate management of pain in all rheumatologic diseases including SSc.     

Comparison of non-cycloplegic photorefraction, cycloplegic photorefraction and cycloplegic retinoscopy in children

AIM: To compare the results of noncycloplegic photorefraction, cycloplegic photorefraction and cycloplegic refraction in preschool and non-verbal children. METHODS: One hundred and ninety-six eyes of 98 children (50 females, 48 males) were included in the study. Firstly, non-cycloplegic photorefraction was achieved with Plusoptix A09; secondly, cycloplegic photorefraction was carried out with Plusoptix A09 after 10 min cyclopentolate. Finally, 30min after instillation of twice cyclopentolate, cycloplegic refraction was obtained with autorefraction and/or standard retinoscopy. Spheric equivalent, spheric power, cylindric power and cylindrical axis measurements were statistically compared. RESULTS: The mean age was 28.8±18.5mo (range 12-72mo). The differences in spherical equivalent, spheric power and cylindrical power measured by the three methods were found statistically significant (P<0.05). The spherical equivalent and spheric power measured by cycloplegic photorefraction were statistically higher than the measurements of the other methods (P<0.05). The cylindrical power measured by cycloplegic refraction was statistically lower than the measurements of the photorefraction methods (P<0.05). There was no significant difference in cylindrical axis measurements between three methods (P>0.05). CONCLUSION: For the determination of refractive errors in children, the Plusoptix A09 measurements give incorrect results after instillation of cyclopentolate. Additionally, the cylindrical power measured by Plusoptix A09 with or without cycloplegia is higher. However, the non-cycloplegic Plusoptix A09 measures spheric equivalent and spheric power similar to cycloplegic refraction measurements in preschool and non-verbal children.     

Exercise-induced pulmonary arterial hypertension in patients with systemic sclerosis

INTRODUCTION: Pulmonary arterial hypertension (PAH) is the most common cause of scleroderma-related deaths. New medications for PAH patients make it necessary to identify patients with high risk factors for PAH. This study looks at the use of an exercise echocardiogram in identifying patients who may have PAH and may be candidates for early therapeutic intervention. METHODS: This study included 54 scleroderma patients with symptoms suggesting they were at risk for pulmonary hypertension, including dyspnea on exertion, diffusing capacity of the lung for carbon monoxide (Dlco)<60% of predicted, FVC<70% of predicted, percentage of predicted FVC/percentage of predicted Dlco (FVC%/Dlco%) ratio>1.6, or resting right ventricular systolic pressure (RVSP)>35 mm Hg. The exercise echocardiogram protocol involved the standard Bruce stress echocardiogram protocol with remeasurement of the RVSP within 1 min of stopping exercise. A positive exercise test result was defined as an increase of at least 20 mm Hg in the RVSP with exercise. Right-heart catheterization with exercise was performed in those with a positive exercise test result. RESULTS: Resting mean RVSP was 34.5 mm Hg, which increased to 51.4 mm Hg with exercise; 44% had at a positive exercise test result, which correlated with a low Dlco, high FVC%/Dlco% ratio (p<0.001), a positive anti-centromere antibody, and RVSP>35 mm Hg (p<0.05). PAH was confirmed by right-heart catheterization in 81% of patients: 19% at rest and 62% of patients with exercise. CONCLUSIONS: Exercise-induced pulmonary hypertension is a common finding in patients at high risk for PAH. This may be a sensitive way to identify patients with early PAH. Long-term follow-up and early treatment should be studied in these patients.     

Procalcitonin in patients with acute coronary syndrome: correlation with high-sensitive C-reactive protein, prognosis and severity of coronary artery disease

OBJECTIVES: The aim of this study is to determine the relation of high-sensitive serum C-reactive protein (hsCRP) and procalcitonin with presence and severity of coronary artery disease and early prognosis in patients with acute coronary syndrome (ACS). METHODS AND RESULTS: Procalcitonin and hsCRP levels were measured at admission and after 48 hours in 50 patients (41 men, 9 women) with ACS. The patients were assigned to three groups according to their clinical diagnosis: unstable angina pectoris (UAP) (Braunwald III-B), non-ST-segment elevation myocardial infarction (NSTEMI) and ST-segment elevation myocardial infarction (STEMI). Incidences of adverse cardiac events were recorded in a 3-month follow-up. Coronary angiography was performed to evaluate presence and severity of coronary artery disease. In the groups of STEMI, NSTEMI and UAP, procalcitonin (P = 0.01 3, P = 0.045 and P = 0.000 1, respectively) and hsCRP (P = 0.000 1, P = 0.01 and P = 0.00 1, respectively) levels were significantly increased. No significant correlation was found between these markers and the presence and severity of coronary artery disease.There was no correlation between procalcitonin and hsCRP levels at admission and after 48 hours and primary end points after 3 months except in the group of UAP with revascularization procedure. In the group of UAP, hsCRP levels at 48 hours were found higher in the patients with a revascularization procedure (P = 0.04). CONCLUSIONS: In conclusion, levels of hsCRP and procalcitonin are increased in patients with ACS but failed to correlate with severity of coronary disease and early prognosis.     

Effect of percutaneous transluminal coronary angioplasty on QT dispersion and heart rate variability parameters

Background

The aim of the study was to analyse parameters reflecting the sympathovagal control of ventricular depolarisation and repolarisation [heart rate variability (HRV) and QT interval dispersion (QTd)] in patients undergoing elective percutaneous transluminal coronary angioplasty (PTCA), and determine whether HRV correlates with QT dispersion parameters.

Methods

The study consisted of 26 consecutive patients (16 men, 10 women) with single-vessel coronary artery disease (CAD) who underwent elective coronary angioplasty. HRV analyses of all subjects were obtained with the time- and frequency-domain methods. For frequency-domain analysis, low-frequency HRV (LF), high-frequency HRV (HF) and the LF:HF ratio were measured. For time-domain analysis, standard deviations of the normal-to-normal QRS intervals (SDNN) and square roots of the mean squared differences of successive N–N intervals (rMSSD) were obtained. QT intervals were also corrected for heart rate using the Bazett’s formula, and the corrected QT interval dispersion (QTcd) was then calculated. All measurements (HRV parameters and QTcd) were made before and immediately after PTCA.

Results

QTcd was significantly decreased after PTCA (52.2 ± 3.5 vs 42 ± 3.9 ms). SDNN (94.1 ± 22 vs 123.9 ± 35.2 ms), rMSSD (43.7 ± 20.1 vs 73.4 ± 14.5 ms) and HF (51.1 ± 48.8 vs 64.2 ± 28.6 ms²) were significantly higher after PTCA, whereas LF (142 ± 41.5 vs 157.2 ± 25.9 ms²) and the ratio of LF:HF (3.3 ± 1.9 vs 2.1 ± 1.2) were significantly decreased after PTCA. We observed a significant negative correlation after PTCA between QTcd and LF (r = −0.87, p = 0.01) and between QTcd and the ratio of LF:HF (r = −056, p < 0.05).

Conclusion

Among the patients with CAD undergoing PTCA, QTcd significantly decreased after PTCA, and negatively correlated with LF, the parameter reflecting the sympathetic system.
