BACKGROUNDThe emerging role of vitamin D in immunology and autoimmune disorders has been a worldwide interest in the last decade. Systemic lupus erythematosus (SLE) patients are particularly at a delicate position predisposing them to suffer from vitamin D deficiency due to the multiple risk factors accompanying the disease. Whether vitamin D deficiency is also involved as a risk factor for developing SLE and affecting its course is a considerable concern.OBJECTIVESThe objective of this study was to estimate the prevalence of vitamin D deficiency in SLE patients and its relation to disease.MATERIALS AND METHODSIn our observational cross-sectional study, serum levels of vitamin D [25(OH)D] in 60 SLE patients and 30 age- and sex-matched healthy controls were assessed and estimated for deficiency and insufficiency at 10 and 30 ng/mL, respectively. Disease activity was evaluated by SLE disease activity index (SLEDAI), irreversible organ damage by Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SLICC/ACR DI), and severity by Severity of Disease Index. Fatigue was measured by visual analog scale.RESULTSSignificantly lower levels of 25(OH)D were found in SLE patients (17.6 ± 6.9 ng/mL) in comparison to controls (79.0 ± 28.7 ng/mL), with a statistically high significant difference (t = −11.2, P < 0.001). High prevalence of vitamin D insufficiency and deficiency was detected as 73.3% and 23.3%, respectively. Vitamin D had a highly significant negative correlation with SLEDAI (r = −0.495, P < 0.001), SLICC (r = −0.431, P < 0.05), and fatigue (r = −0.436, P < 0.05).CONCLUSIONVitamin D deficiency and insufficiency were found to be prevalent in SLE patients in our study and related to disease activity and fatigue. If needed, routine screening and consequent repletion of vitamin D are recommended in SLE patients. Restoring adequate vitamin D levels in SLE patients should be more explored as a potential yet simple measure to their usual management to improve their condition.

During the coronavirus disease-2019 (COVID-19) pandemic there were several barriers to treatment access and medication adherence in rheumatoid arthritis (RA) patients. There is no information regarding the RA patient health status in Egypt during the COVID-19. Thus,the aim of this work was to study the impact of the pandemic on RA patients through a patient-reported questionnaire and to determine the influence of gender, geographic regions. This multi-centre study initiated by the Egyptian College of Rheumatology (ECR) was conducted on 1037 RA patients attending rheumatology clinics from 10 governorates. The questionnaire provided covered socio-demographic data, health/disease status, information/knowledge about COVID-19 and medical/family history of the infection. Patients mean age was 44.2 ± 12.3 years;855 females and 182 males; 539(52%) from rural and 497(48%) from urban areas. 41.8% reported a striking difficulty to obtain hydroxychloroquine during the pandemic. The majority (70%) considered maintaining a regular visit to the rheumatologist in addition to remote contact mainly by phone (44.4%) or via WhatsApp (33.1%), in particular among male and urban patients. Urban patients were more likely to be infected by COVID-19 (12.9% vs 6.2%; p < 0.0001) than rural. Northern cities had more patients with suspected COVID-19 (13.9% vs 6.1%; p < 0.0001); was significantly associated with more disease flares (30.8% vs 5.8%) with subsequent change in the RA treatment (20.9% vs 6.4%; p < 0.0001). Patients with RA faced remarkable difficulty to obtain their medications with subsequent change in their disease status. The challenges of the pandemic have hastened changes in the way we deliver health care.

Background: Metabolic syndrome (MetS) is characterized by insulin resistance, high blood pressure/sugar, dyslipidemia, and obesity. Whether MetS and its components affect the development of Behçet's Disease (BD) remains unclear. Aims: The aim was to determine the frequency of MetS among BD patients and to study its relation to the disease characteristics. Methods: The study included 1028 adult BD patients recruited from 18 specialized rheumatology centers. 51 healthy matched control were considered. Behçet Disease Current Activity Form (BDCAF) and the BD damage index (BDI) were estimated. Adult Treatment Panel-III criteria were used to define MetS. Results: The mean age of patients was 36.8±10.1 years, M:F 2.7:1 and disease duration 7.01±5.2 years. Their mean BDCAF was 5.1±4.6 and BDI 5.5±2.8. MetS was present in 22.8% of patients and in 5.9% of control (3.9 fold higher-risk). Patients with MetS had a significantly increased age at onset (31.8±9.2 vs 29±8.5 years) and higher frequency of genital ulcers (96.2% vs 79.7%), skin involvement (73.1% vs 50.4%), arthritis (48.3% vs 29.1%)(p<0.0001) and CNS manifestations (18.8% vs 13%)(p=0.042) compared to those without. Eye involvement was significantly increased in those with MetS (82.1% vs 74.2%)(p=0.003) with increased frequency of posterior uveitis (67.1% vs 43.5%), retinal vessel occlusion (35.9% vs 21.3%), retinal vasculitis (41.9% vs 26.4%)(p<0.0001) and vitritis (37.2% vs 24%)(p=0.001). BDCAF was significantly lower (3.9±4.3 vs 5.6±4.6) and BDI higher (7.4±2.7vs5±2.6)(p<0.0001). Conclusion: BD patients with MetS are predisposed to mucocutaneous, musculoskeletal, neuropsychiatric and ocular manifestations with consequently increased damage. The affection of the deeper structures of the eye should alarm rheumatologists to keep in mind that all patients should have an eye examination especially those with MetS.

Background Achilles tendinopathy (AT) is considered the commonest tendon pathology, occurring mainly in athletes. Different conservative treatment options have been introduced but with short-term effects; however, extracorporeal shockwave therapy (ESWT) and mesotherapy (MT) injections were claimed to provide longer effects and could be used in cases failure of response to conservative treatments. The objective of our prospective 12-week study was to compare the effect of ESWT and MT on chronic Achilles tendinopathy in athletes by both clinical and ultrasonographical assessment. Results Forty patients with chronic AT diagnosed clinically and with high-resolution ultrasound (US) randomly allocated in two groups first received weekly ESWT session, and the other group underwent weekly MT sessions for 4 consecutive weeks. Both groups improved during the treatment and follow-up period. The mean visual analogue score (VAS) decreased in both the ESWT group and the MT group. Mean American Orthopedic Foot and Ankle Society (AOFAS) hindfoot score and VAS scores were not significantly different between ESWT and MT groups at the 4th and the 12th week of follow-up. However, US assessment significantly improved after 12 weeks in the ESWT group (as regards tendon thickness, calcifications, and Doppler signal), and for the mesotherapy group, there was the only improvement of tendon thickness. Conclusion ESWT showed improvement of pain and inflammation and calcifications of AT than MT injections, which was documented by US improved findings at week 12 follow up.
