Objective To assess the frequency of fibromyalgia (FM) in patients with psoriatic arthritis (PsA) and its impact on disease activity indices, fatigue and health‐related quality of life (QOL). Methods This cross‐sectional study randomly recruited patients with PsA attending an outpatient clinic between June 2017 and December 2018. Disease activity, functional ability, fatigue, and QOL were assessed for all patients. The recruited PsA patients were screened for concomitant FM, then classified into group Ι, patients with PsA only, and group ΙI, patients with FM‐PsA. The severity and impact of FM were assessed for group II patients. Results A total of 60 patients with PsA were assessed with a mean age of 49.30 ± 11.69 years, of which 43.3% were female. A total of 23 PsA patients had concomitant FM (38.3%). Patients with FM‐PsA showed a statistically higher disease activity in all aspects of PsA except for C‐reactive protein, swollen joint count (SJC) and dactylitis count. Patients in both groups had similar functional levels, while fatigue and QOL were statistically worse in patients with FM‐PsA than in patients with PsA only. Conclusion These results might highlight the importance of considering FM as a contextual factor in disease activity assessment in patients with PsA, especially in those with discrepancies in tender joint count/patient‐reported outcomes vs SJC/inflammatory markers and those with persistently high disease activity indices.

Objectives Anti-carbamylated protein antibodies (anti-CarP Abs) are present in patients with RA, however, their association with bone loss is not confirmed. The purpose of this study was to determine the relation between the serum level of anti-CarP Abs in premenopausal RA women and disease activity and bone loss. Methods This case–control study was conducted on 48 premenopausal women with RA and 48 matched healthy premenopausal women. All RA women were subjected to clinical examination, disease activity assessment using the 28-joint DAS (DAS28) and Clinical Disease Activity Index (CDAI), functional assessment using the HAQ, physical activity assessment using the International Physical Activity Questionnaire (IPAQ), fatigue assessment using the Modified Fatigue Impact Scale (MFIS), serological tests as well as anti-CarP Abs using ELISA. Moreover, the BMD was measured by DXA and plain X-ray of both hands was done to assess juxta-articular osteopenia and erosions. Results The anti-CarP Abs level was significantly higher in RA patients than in healthy controls. The serum level of anti-CarP Abs had a significant positive correlation with the RA DAS28, CDAI, HAQ, MFIS and original Sharp score, while a significant negative correlation was present with the IPAQ. Anti-CarP Abs were negatively correlated with either spine BMD or Z-score and positively correlated with the original Sharp score. Conclusion Anti-CarP Abs were higher in premenopausal RA women compared with older and BMI matched healthy women. Anti-CarP Abs are associated with higher RA disease activity, increased disability and fatigability and decreased physical activity. Moreover, anti-CarP Abs are associated with systemic trabecular bone loss as well as local bone loss.

Background A major problem in surgery of peripheral nerve injuries of the upper extremities is the unpredictable final outcome. More insight and understanding of the proper methods of outcome assessment and the prognostic factors is necessary to improve functional outcome after repair of peripheral nerves. The objective of this study is to assess the outcome and identify possible prognostic factors for functional recovery of median and/or ulnar nerves repairs at wrist. Forty patients with median, ulnar or combined median-ulnar nerve injuries were included. Smoking, age, sex, repaired nerve, associated artery and/ or tendon repairs, joint stiffness and scar tissue were analyzed as prognostic factors for functional outcome after repair. Outcome parameters were medical research counsel (MRC) scoring for sensory and motor recovery, grip and pinch strength, disability of arm, shoulder and hand (DASH) questionnaire, electrophysiology and ultrasonographic evaluation. Results The mean age of the studied patients was 29.1 ± 8.3 and it was statistically correlated with grip strength (p = 0.045), DASH score (p = 0.046) and hyperesthesia score (p = 0.040). EMG results showed signs of regeneration in all patients in the form of small nascent MUAPs and polyphasic MUAPs. CMAP amplitudes of median and ulnar nerves positively correlated with the MRC scale for muscle strength (p = 0.001) There were statistically significant negative correlations between DASH score and MRC score for sensory evaluation (p = 0.016), grip (p = 0.001), and pinch strength (p = 0.001). There were statistically significant positive correlations between patient's opinion of recovery and MRC score for sensory evaluation (p = 0.029), grip (p = 0.001), and pinch strength (p = 0.001). The MRC score for muscle strength has statistical significant positive correlations with the MRC score for sensory evaluation, grip (p = 0.003), and pinch strength (p = 0.040) Conclusions It was concluded that; MRC scale for muscle power, MRC scale for sensory evaluation, functional scores, grip and pinch strength are valuable tools for evaluation of functional outcome. Age, smoking, associated tendon repair, damaged nerve, compliance to rehabilitation protocol, return to work, clinically visible wound adhesions, residual hand joint stiffness, and scar tissue detected by ultrasound were found to be prognostic factors for outcome after nerve repair.

Objective To assess interleukin 23 (IL-23) levels in the sera of psoriatic arthritis (PsA) patients and to determine the relationship of IL-23 with different disease activity indices, physical function and quality of life (QoL). Methods Fifty PsA patients and 46 matched healthy controls were included in this study. Data including a detailed history, a thorough clinical examination, skin severity based on the Psoriasis Area and Severity Index (PASI), the Disease Activity index for Psoriatic Arthritis (DAPSA) and the Composite Psoriatic Disease Activity Index (CPDAI) were obtained for all patients. Physical function was assessed by the Health Assessment Questionnaire Disability Index (HAQ-DI) and health-related QoL was assessed using the Short Form Health Survey (SF-36), Psoriatic Arthritis Quality of Life (PsAQoL) and the Dermatology Life Quality Index (DLQI) were also assessed. Serum IL-23 levels were measured in the studied groups. Results The study included 23(46%) females and 27 (54%) males with a mean age of 42.78±12.33 years. The mean serum IL-23 level was significantly higher in PsA patients (50.89±13.86 pg/ml) than in controls (43.88±6.34 pg/ml) (p=0.006). There were significant correlations between serum IL-23 levels and different grades of DAPSA activity (p=0.007) and PASI (p=0.015). No significant correlations could be detected between serum IL-23 levels and (HAQ-DI, DLQI, SF-36 or PsAQoL). CPDAI and DAPSA were significantly correlated with DLQI, SF-36 and PsAQoL. Conclusion IL-23 is a useful biomarker for identifying joint activity or skin severity but not QoL or physical function.
