Factors affecting the tuberculosis risk in patients receiving anti-tumor necrosis factor-α treatment.

BACKGROUND: Tumor necrosis factor (TNF)-α inhibitors are known to increase the risk of tuberculosis (TB). OBJECTIVES: To examine the factors associated with an increased risk of TB in patients receiving anti-TNF-α treatment (aTNF-α-T). METHOD: Of 3,094 patients who received aTNF-α-T between 2003 and 2013, a total of 1,964 subjects with a follow-up time longer than 6 months were identified and included in this retrospective analysis. Potential risk factors for the development of TB in patients receiving aTNF-α-T were evaluated. RESULTS: Of the 1,964 patients, 1,009 (51%) were male and 955 (49%) were female, with a mean age of 39.7 ± 13.9 years. The primary conditions requiring aTNF-α-T included ankylosing spondylitis (n = 875), rheumatoid arthritis (n = 711), Behçet's disease (n = 83), and others (n = 295). Sixteen patients [8 (50%) males and 8 (50%) females; 5 (31.2%) with pulmonary TB and 11 (68.8%) with extrapulmonary TB] developed TB, with a corresponding TB incidence of 466/100,000. No significant associations were found between age, gender, smoking history, pack-years of smoking, isoniazid (INH) chemoprophylaxis, type of anti-TNF-α agent, use of other immunosuppressive drugs, and the risk of TB (p > 0.05). Multivariate logistic regression analysis showed a significantly higher risk of TB in patients diagnosed with Behçet's disease, and a significantly lower risk of TB in patients with a tuberculin skin test wheal ≥10 mm in diameter (p < 0.05). CONCLUSION: aTNF-α-T is associated with an increased risk of pulmonary or extrapulmonary TB, even when follow-up protocols and INH chemoprophylaxis are implemented, and TB often develops in the later stages of treatment. The risk of TB was higher in patients with Behçet's disease and lower in patients who had a strong tuberculin skin test reaction.

Prevalence and risk factors for self-reported symptoms of carpal tunnel syndrome among hospital office workers: a cross-sectional study.

Objectives. We aimed to determine the prevalence of self-reported symptoms of carpal tunnel syndrome (CTS) and associated risk factors among hospital office workers. Methods. This cross-sectional study was carried out between May and August 2021 with office workers actively working in a hospital in Izmir, Turkey. The Boston carpal tunnel syndrome questionnaire was used to evaluate the severity of self-reported CTS symptoms and their effect on the functional status of the participants. Results. The study included 151 people, 68.2% of whom were women. CTS symptoms were reported by 74.1% of the participants, the majority of whom (73.2%) were women. These reported symptoms were mild in 43%, moderate in 24.5%, severe in 5.3% and very severe in 1.3%. Significant differences were found between those with and without CTS symptoms regarding age, body mass index, previous diagnosis of CTS, daily work hours, using a wrist-supported mousepad and perceived workload (p < 0.05). Conclusion. CTS symptoms of office workers in the hospital were associated with occupational characteristics as well as individual factors. These risk factors should be taken into account while planning for future preventive and interventional measures in workplaces.

Coronavirus Disease 2019 in Patients with Asthma: Case Study from a Tertiary Center Regarding Their Phenotypes and Their Adherence to Asthma Treatment by Telemedicine.

OBJECTIVE: The aim of this study was to determine the prevalence and the characteristics of coronavirus disease 2019 (COVID-19) in a tertiary outpatient clinic of asthma patients, find the predisposing asthma phenotype to COVID-19, and to see their adherence to asthma treatment. MATERIAL AND METHODS: A retrospective, cross-sectional, real life study was conducted via phone interviews with the patients being followed in the asthma outpatient clinic. From the files of the patient information was obtained about their demographics, asthma phenotype, co-morbidity, prick tests, spirometry test results and their medications at the last visit before the COVID-19 pandemic. Information's about asthma exacerbations, ACT, asthma treatment adherence and history of COVID-19 were obtained via telephone interviews. RESULTS: Of the 573 patients with asthma, 13 (2.26%) had COVID-19 history. The mean age of patients with asthma and COVID-19 was 51.84±14.92 year. Two patients were on mepolizumab and one was on omalizumab treatment. Mean ACT was 19.84±2.73. Lack of adherence was reported in 8% of all patients with asthma compared to 23% in the patients who had COVID-19. Asthma exacerbation was seen during the course of SARS-CoV2 infection in 3 of 13 patients with asthma. Asthma exacerbations were reported during the period of one month following COVID-19 in 2 patients. CONCLUSION: The most common asthma phenotype in the cases of COVID-19 was obese phenotype. Rates of using biological agents and non-adherence to the treatment were found to be higher. Asthma exacerbation may be seen during course of COVID-19 albeit being less common.

Investigation of perfusion defects by Q-SPECT/CT in patients with mild-to-moderate course of COVID-19 and low clinical probability for pulmonary embolism.

OBJECTIVE: Pulmonary embolism is a severe source of mortality and morbidity in patients with severe and critical coronavirus disease 2019. It is not yet clear whether the tendency to thrombosis is increased in the mild-to-moderate course of COVID-19. Our research aims to show the clinical benefit of Q-SPECT/CT in diagnosing PD in outpatients treated with mild-to-moderate course of COVID-19 and to determine the frequency of perfusion defects in these patients having relatively lower risk. METHODS: All patients who underwent Q-SPECT/CT with suspicion of embolism were examined retrospectively. Only patients with low clinical probability and mild-to-moderate course of COVID-19 for PE were included in the study. The patients were evaluated comparatively as those with and without perfusion defects. Patients were divided into laboratory suspicion, clinical suspicion, or clinical and laboratory suspicion. RESULTS: In outpatients with mild-to-moderate COVID-19 with low clinical probability for PE, PD without CT abnormality was detected with a rate of 36.6% with Q-SPECT/CT performed for complaints of high D-dimer and/or dyspnea. None of the patients had PD at more proximal level than the segment level. PD with no concomitant CT abnormality was observed with a rate of 56.5% in patients with both clinical and laboratory suspicion. For D-dimer = 0.5 mg/dL cut-off sensitivity is 85%, for D-dimer = 1.5 mg/dL cut-off specificity 81%. CONCLUSION: Thrombosis tendency is also present in outpatients with mild-to-moderate COVID-19, and these patients should also be offered anticoagulant prophylaxis during the COVID-19 period.
