A follow-up study of the occurrence and consequences of HbA1c measurements in an unselected cohort of non-pharmacologically treated patients with Type 2 diabetes.

ABSTRACT: OBJECTIVES: To describe the occurrence of HbA1c measurements among non-pharmacologically treated diabetes patients, and to evaluate whether poor blood glucose regulation (HbA1c >8%) prompted intensification of treatment. METHOD: Data from the National Health Service Registry, the Regional Laboratory Database and the Danish National Hospital Registry were collected from 2002 to 2004 to identify and describe all Type 2 diabetic patients above 40 years of age in a background population of nearly 660,000 citizens in Aarhus County, corresponding to 12% of the total Danish population. RESULTS: A total of 1989 had at least one HbA1c measurement, whereas 484 (20%) had no HbA1c measurement at all in 2003. Most patients had an HbA1c of less than 8%, and for 820 (41%) HbA1c was less than 6.5%, but for 316 (16%) patients, the first HbA1c measurement in 2003 was above 8%. After 6 months, patients with HbA1c above 8% had a higher probability of initiating pharmacological treatment (M; 0.64; 95% CI 0.58-0.70) (F; 0.68; 95% CI 0.58-0.77) than patients with HbA1c below 8% (M; 0.12; 95% CI 0.10-0.14) (F; 0.11; 95% CI 0.09-0.14). CONCLUSION: This study indicates that poor blood glucose regulation (HbA1c >8%) prompted a shift from non-pharmacological treatment to pharmacological treatment for most patients. However, a substantial group of patients are either not monitored on a regular basis or, if monitored, their elevated measurements of HbA1c do not prompt initiation of pharmacological treatment.

Project description:Objectives: IgG4-related disease (IgG4-RD) is a chronic fibro-inflammatory disorder affecting virtually any organ. Type 1 autoimmune (type 1 AIP) is its pancreatic manifestation. To date, steroids are considered the first-line pancreatitis treatment. The CD20-binding antibody rituximab (RTX) appears a promising steroid-sparing therapy, although long-term data are lacking. We aimed to bridge this gap with a cohort of IgG4-RD patients treated with RTX and to assess the potential value of the Responder Index (RI) as a discriminatory score for disease activity. Methods: We retrospectively evaluated 46 patients from a tertiary referral centre who were diagnosed with IgG4-RD and/or type 1 AIP according to the International Consensus Diagnostic Criteria or Unifying-AIP criteria between June 2006 and August 2019. Results: Patients resembled previous cohorts in terms of characteristics, diagnosis, and therapeutic response. Thirteen of the 46 patients with IgG4-RD/type 1 AIP were treated with RTX pulse therapy due to relapse, adverse reactions to steroids, or high-risk constellations predicting a severe course of disease with multi-organ involvement. Median follow-up after diagnosis was 52 months for all subjects, and 71 months in IgG4-RD patients treated with RTX. While patients in the RTX group showed no significant response to an initial steroid pulse, clinical activity as measured by the RI significantly decreased in the short-term after RTX induction. Within 16 months, 61% of patients relapsed in the RTX group but responded well to re-induction. Clinical and laboratory parameters improved equally in response to RTX. Conclusion: RTX therapy in patients with IgG4-RD is an effective and safe treatment to induce treatment response and possible long-term remission. Repeated RTX administration after 6–9 months may be of value in reducing the risk of relapse. The RI appears to be a reasonable index to assess disease activity and to identify patients with IgG4-related disease who may benefit from B-cell-depleting therapy.

Project description:BackgroundWe evaluated the radiologic, pulmonary functional, and antibody statuses of coronavirus disease 2019 (COVID-19) patients 6 and 18 months after discharge, comparing changes in status and focusing on risk factors for residual computed tomography (CT) abnormalities.MethodsThis prospective cohort study was conducted on COVID-19 patients discharged between April 2020 and January 2021. Chest CT, pulmonary function testing (PFT), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunoglobulin G (IgG) measurements were performed 6 and 18 months after discharge. We evaluated factors associated with residual CT abnormalities and the correlation between lesion volume in CT (lesionvolume), PFT, and IgG levels.ResultsThis study included 68 and 42 participants evaluated 6 and 18 months, respectively, after hospitalizations for COVID-19. CT abnormalities were noted in 22 participants (32.4%) at 6 months and 13 participants (31.0%) at 18 months. Lesionvolume was significantly lower at 18 months than 6 months (P < 0.001). Patients with CT abnormalities at 6 months showed lower forced expiratory volume in 1 second (FEV1) and FEV1/forced vital capacity (FVC), and patients with CT abnormalities at 18 months exhibited lower FVC. FVC significantly improved between 6 and 18 months of follow-up (all P < 0.0001). SARS-CoV-2 IgG levels were significantly higher in patients with CT abnormalities at 6 and 18 months (P < 0.001). At 18-month follow-up assessments, age was associated with CT abnormalities (odds ratio, 1.17; 95% confidence interval, 1.03-1.32; P = 0.01), and lesionvolume showed a positive correlation with IgG level (r = 0.643, P < 0.001).ConclusionAt 18-month follow-up assessments, 31.0% of participants exhibited residual CT abnormalities. Age and higher SARS-CoV-2 IgG levels were significant predictors, and FVC was related to abnormal CT findings at 18 months. Lesionvolume and FVC improved between 6 and 18 months.Trial registrationClinical Research Information Service Identifier: KCT0008573.
