Hernández-Molina, G., B. Kostov, P. Brito-Zerón, A. Vissink, T. Mandl, A. C. Hinrichs, L. Quartuccio, C. Baldini, R. Seror, A. Szántó, et al., "Characterization and outcomes of 414 patients with primary SS who developed hematological malignancies.", Rheumatology (Oxford, England), 2022. Abstract

OBJECTIVE: To characterize 414 patients with primary SS who developed hematological malignancies and to analyze how the main SS- and lymphoma-related features can modify the presentation patterns and outcomes.

METHODS: By January 2021, the Big Data Sjögren Project Consortium database included 11 966 patients fulfilling the 2002/2016 classification criteria. Hematological malignancies diagnosed according to the World Health Organization (WHO) classification were retrospectively identified.

RESULTS: There were 414 patients (355 women, mean age 57 years) with hematological malignancies (in 43, malignancy preceded at least one year the SS diagnosis). 376 (91%) patients had mature B cell malignancy, nearly half MALT lymphoma (n = 197), followed by DLBCL (n = 67), nodal MZL lymphoma (n = 29), CLL/SLL (n = 19) and follicular lymphoma (n = 17). Rates of complete response, relapses and death were 80%, 34% and 13%, respectively, with a 5-year survival rate of 86.5% after a mean follow-up of 8 years. There were significant differences in age at diagnosis (younger in MALT, older in CLL/SLL), predominant clinical presentation (glandular enlargement in MALT lymphoma, peripheral lymphadenopathy in nodal MZL and FL, constitutional symptoms in DLBCL, incidental diagnosis in CLL/SLL), therapeutic response (higher in MALT lymphoma, lower in DLBCL) and survival (better in MALT, nodal MZL and FL, worse in DLBCL).

CONCLUSION: In the largest reported study of hematological malignancies complicating primary SS, we confirm the overwhelming predominance of B cell lymphomas, especially MALT, with the salivary glands being the primary site of involvement. This highly-specific histopathological scenario is linked with the overall good prognosis with a 5-year survival rate of nearly 90%.

Tharwat, S., S. S. ElAdle, A. H. Moshrif, F. Ismail, R. El-Shereef, E. A. Talaat, S. Hassanein, Y. Hisham, and T. A. Gheita, "Computed tomography pulmonary angiography (CTPA) in Behçet's disease patients: a remarkable gender gap and time to refine the treatment strategy.", Clinical rheumatology, vol. 41, issue 1, pp. 195-201, 2022. Abstract

OBJECTIVE: The aim of the work was to delineate the computed tomography pulmonary angiography (CTPA) findings in Behçet's disease (BD) patients with and without chest manifestations.

PATIENTS AND METHODS: The study included 122 BD adults recruited from 5 Teaching University Hospitals in Egypt of those who agreed to perform a CTPA. The Arabic version of BD current activity form (BDCAF) and BD damage index (BDI) were assessed. Detailed pulmonary manifestations, examination, plain radiology chest, and CTPA findings were recorded.

RESULTS: The mean age of patients was 36.9 ± 11.3 years, male:female was 1.8:1, disease duration 9.6 ± 8.2 years, and age at onset 28.3 ± 8.6 years. Their mean BDCAF was 4.4 ± 2.2 and BDI 3.4 ± 1.8. There were chest manifestations in 51 (41.8%) and plain chest x-ray findings in 13 (10.7%) and CTPA findings in 31 (25.4%) in the form of pulmonary thromboembolism in 15 (12.3%), pulmonary aneurysms in 7 (5.7%), pneumonia in 5 (4.1%), interstitial lung disease in 4 (3.3%) and pleural effusion in 3 (2.5%). Patients with chest manifestations had significantly higher frequency of cardiac manifestations (15.7%) compared to those without (2.8%; p = 0.023); chest x-ray findings tended to be higher (17.6% vs 5.6%; p = 0.05) while CTPA findings were significantly detected (51% vs 7%; p < 0.0001). Higher frequency of CTPA findings were in females (p < 0.0001). Yet the rate of serious pulmonary embolisms, aneurysms, and thrombosis was exclusive in males.

CONCLUSION: Meticulous investigation of the chest manifestations is warranted in BD patients to undermine the actual magnitude of pulmonary impact. CTPA provides a realistic estimate of the extent of involvement even in asymptomatic cases. Key Points • Meticulous chest assessment is warranted in Behçet's disease patients to undermine the actual magnitude of pulmonary impact • CTPA provides a realistic estimate of the extent of involvement even in asymptomatic cases.

Sen, P., L. Gupta, J. B. Lilleker, V. Aggarwal, S. Kardes, M. Milchert, T. Gheita, B. Salim, T. Velikova, A. E. Gracia-Ramos, et al., "COVID-19 vaccination in autoimmune disease (COVAD) survey protocol.", Rheumatology international, vol. 42, issue 1, pp. 23-29, 2022. Abstract

The coronavirus disease-2019 (COVID-19) pandemic continues to be a cause of unprecedented global morbidity and mortality. Whilst COVID-19 vaccination has emerged as the only tangible solution to reducing poor clinical outcomes, vaccine hesitancy continues to be an obstacle to achieving high levels of vaccine uptake. This represents particular risk to patients with autoimmune diseases, a group already at increased risk of hospitalization and poor clinical outcomes related to COVID-19 infection. Whilst there is a paucity of long-term safety and efficacy data of COVID-19 vaccination in patients with autoimmune diseases, the current evidence strongly suggests that the benefits of vaccination outweigh the risks of adverse effects and disease flares. Herein, we report the protocol of the COVID-19 Vaccination in Autoimmune Diseases (COVAD) study, an ongoing international collaborative study involving 29 countries and over 110 investigators.

Abstract

Imaging has long been taking its place in the diagnosis, monitor, and prognosis of rheumatic diseases. It plays a vital role in the appraisal of treatment. Key progress in the clinical practice of rheumatology is the innovation of advanced imaging modalities; such as musculoskeletal ultrasound (MSUS), computerized tomography (CT) and magnetic resonance imaging (MRI). These modalities introduced a promising noninvasive method for visualizing bone and soft tissues to enable an improved diagnosis. The use of MSUS in rheumatology is considered a landmark in the evolution of the specialty and its ease of use and many applications in rheumatic diseases make it a forerunner instrument in the practice. The use of MSUS among rheumatologists must parallel the development rate of the excellence revealed in the specialty. Moreover, innovative interventional imaging in rheumatology (III-R) is gaining fame and key roles in the near future for a comprehensive management of rheumatic diseases with precision. This review article throws light on the emergence of these robust innovations that may reshape the guidelines and practice in rheumatology, in particular, efforts to enhance best practice during the coronavirus disease 2019 (COVID-19) pandemic are endorsed.

Medhat, E., G. Ayeldeen, H. H. Ahmed, O. Shaker, T. Gheita, and S. S. Ashour, "HOTAIR and THRIL Long Non Coding RNAs and Their Target Genes in Rheumatoid Arthritis patients.", Reports of biochemistry & molecular biology, vol. 10, issue 4, pp. 614-621, 2022. Abstract

Background: Rheumatoid arthtritis (RA) is a chronic systemic inflammatory autoimmune disease characterized by irreversible joint damage and deformity. The aim of this study is to investigate THRIL and HOTAIR serum expression and their target genes in Egyptian RA patients and to evaluate their relationship to the clinico-pathological data.

Methods: The present study included fifty-two RA patients and fifty-six healthy controls. RA patients were classified according to DAS28 score. All subjects were subjected to full history taking and clinical examination. Quantitative real time PCR was done to estimate the expression levels of serum THRIL and HOTAIR as well as their target genes tumor necrosis factor alpha (TNF-α) and metalloproteinase 2 (MMP-2) were estimated by ELISA techniques.

Results: Results revealed that both THRIL and HOTAIR were statistically over expressed in RA patients compared to healthy group with p-value< 0.05. Results showed as well that the target genes for those long-non coding RNAs, TNF-α and MMP-2, were also significantly higher in RA patients compared to healthy controls.

Conclusion: Both THRIL and HOTAIR associated with their target genes, can be considered as diagnostic markers for RA.

The study aimed to explore the experience of coronavirus disease-2019 (COVID-19) infection and vaccine adverse events (AEs) among rheumatologists. A validated questionnaire was distributed as a Google form to rheumatologists across the country via social networking sites from late December 2021 till early January 2022. The questionnaire included questions regarding participants' socio-demographic details, COVID-19 infection and vaccination details with special emphasis on AEs. Out of 246 responses, 228 were valid. 200 (81.3%) responders had received the vaccine. The mean age of the 228 participants was 37.9 ± 8.5 years, 196 were females and 32 males (F:M 6.1:1) from 18 governorates across the country. Comorbidities were present in 54 subjects (27%). There was a history of highly suspicious or confirmed COVID-19 infection in 66.7% that were all managed at home. The COVID-19 vaccine was received by 200 and a booster dose of 18.5%. Obesity and musculoskeletal involvement co-morbidities were present only in those with AEs (9.1% and 5.5% respectively). AEs were present in 82%; 66.7% had injection-site tenderness, 50% fatigue, 35.5% fever, 15% chills, 42.5% myalgia, 14.5% arthralgia, 8% low back pain, headache 31%, dizziness 10%, sleepliness 16% and 15% developed post-vaccine. There were no differences according to the geolocation regarding the occurrence of COVID-19 infection (p = 0.19) or AEs post-vaccine (p = 0.58). The adverse events were mostly mild to moderate and tolerable which makes this work in agreement with other studies that support the broad safety of the vaccine in favor of the global benefit from mass vaccination.
