Abstract
BACKGROUND Quantifying glucocorticoid toxicity is crucial to efforts to reduce it. The Glucocorticoid Toxicity Index (GTI) measures toxicity effectively in clinical trials by calculating two scores: the cumulative worsening score (CWS) and the aggregate improvement score (AIS). However, in clinical practice, high patient volumes limit the time available for standardised assessments. We aimed to compare the GTI with an abbreviated version of the GTI, the GTI-Metabolic Domains (GTI-MD), which could help to address this issue by using data that are collected easily at routine visits and do not require additional effort from clinicians. METHODS We did a post-hoc analysis of data from ADVOCATE, a randomised, double-blind, double-dummy, phase 3 trial in which avacopan replaced a standard prednisone taper in patients with antineutrophil cytoplasmic antibody-associated vasculitis. We calculated the cumulative worsening score (CWS) and aggregate improvement score (AIS) for each domain of the GTI-MD-comprising the BMI, glucose tolerance, blood pressure, and lipid metabolism domains of the GTI-to test its ability to differentiate the avacopan and prednisone groups by glucocorticoid toxicity. Data from two additional disease cohorts, one comprising patients with asthma and the other comprising patients with autoimmune blistering disease, constituted the validation set. FINDINGS Complete data were available for 321 (97%) of the 330 participants comprising the intention-to-treat population in the ADVOCATE trial at week 13, and 307 (93%) at week 26; data from these individuals were included in our post-hoc analysis. In ADVOCATE, 98 (59%) of 166 participants in the avacopan group were men and 68 (41%) were women, 88 (54%) of 164 in the prednisone group were men and 76 (46%) were women; the mean age of participants was 61·2 years [SD 14·6] in the avacopan group and 60·5 years [14·5] in the prednisone group. The validation cohort included 159 patients (89 with glucocorticoid-dependent asthma, of whom 40 [45%] were men and 49 [55%] were women, and 70 with autoimmune blistering disease of the skin, of whom 30 [43%] were men and 40 [57%] were women). The Spearman's rank correlation coefficient in ADVOCATE for the GTI-MD CWS with the GTI CWS for the treatment groups combined was 0·78 (95% CI 0·75-0·81; p<0·0001). The corresponding correlation for the AIS was 0·73 (0·69-0·77, p<0·0001). The GTI-MD distinguished the groups by glucocorticoid toxicity at both 13 weeks and 26 weeks. The mean GTI-MD CWS was lower in the avacopan group than in the prednisone group, consistent with less toxicity (15·9 vs 23·0 at 13 weeks [p=0·0010]; 26·7 vs 31·7 at 26 weeks [p=0·0092]). The GTI-MD AIS values were also consistent with less toxicity in the avacopan group (2·5 vs 13·0 at 13 weeks [p=0·0003], 4·4 vs 10·1 at 26 weeks [p=0·027]). A GTI-MD score of 0 corresponded to a low likelihood of toxicity in the other GTI domains. In the validation set, the Spearman's rank correlation coefficient for the GTI-MD CWS with the GTI CWS was 0·61 (95% CI 0·50-0·70; p<0·0001) and the corresponding correlation for the AIS was 0·58 (0·47-0·68; p<0·0001). INTERPRETATION The GTI-MD correlates well with the full GTI and could be incorporated readily into routine clinic workflows without additional input from the clinician. Using the GTI-MD on the background of electronic medical records systems could help clinicians to monitor glucocorticoid toxicity longitudinally, with the goals of preventing the burden of chronic, treatment-related harms and reducing long-term costs to health systems.

Glucocorticoid Toxicity Index scores by domain in patients with antineutrophil cytoplasmic antibody-associated vasculitis treated with avacopan versus standard prednisone taper: post-hoc analysis of data from the ADVOCATE trial. THE LANCET. RHEUMATOLOGY 2023; 5:e130-e138. [PMID: 38251609 DOI: 10.1016/s2665-9913(23)00030-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Revised: 01/05/2023] [Accepted: 01/09/2023] [Indexed: 02/22/2023]
Abstract
BACKGROUND The ADVOCATE trial, in which the complement C5a receptor inhibitor avacopan was compared with a standard prednisone taper in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis, used the Glucocorticoid Toxicity Index (GTI) to measure glucocorticoid toxicity change. We set out to do a post-hoc analysis of the ADVOCATE data to evaluate changes in individual GTI domains and their ability to differentiate treatment groups. METHODS The ADVOCATE trial was a phase 3, double-blind, double-dummy, randomised trial comparing oral avacopan (30 mg) twice daily for 52 weeks plus a prednisone-matching placebo for 20 weeks with oral prednisone tapered over 20 weeks plus an avacopan-matching placebo for 52 weeks in patients with ANCA-associated vasculitis. GTI data were collected within each of the included domains (BMI, blood pressure, glucose tolerance, lipid metabolism, glucocorticoid myopathy, skin toxicity, neuropsychiatric effects, and infections) at baseline, 13 weeks, and 26 weeks. In this post-hoc analysis, we calculated the cumulative worsening score (CWS) and aggregate improvement score (AIS) for each GTI domain, assessed to what extend each domain contributed to the GTI score, and which domains differentiated between the avacopan and prednisone groups. Differences in domain scores between the two groups were compared using Mantel-Haenszel χ2 tests. FINDINGS Among the 330 patients included in the intention-to-treat population of the ADVOCATE trial, 321 (97%) had complete data at week 13 (160 in the avacopan group, and 161 in the prednisone group), and 307 (93%) had complete data at week 26 (154 in the avacopan group, and 153 in the prednisone group) and were assessed in this post-hoc study. In ADVOCATE, mean age in both groups was 61 years (61·2 years [SD 14·6] in the avacopan group; 60·5 years [14·5] in the prednisone group); 98 (59%) of 166 patients in the avacopan group were men and 68 (41%) were women; 88 (54%) of 164 patients in the prednisone group were men and 76 (46%) were women. 278 (84%) of 330 patients were White. The mean glucocorticoid use over 26 weeks was lower in the avacopan group than the prednisone group (1073 mg [SD 1669] vs 3192 mg [1174]). Significantly less glucocorticoid toxicity was observed in the avacopan group than the prednisone group by week 13 in four domains of the GTI (BMI, glucose tolerance, lipid metabolism, and skin toxicity), based on both the CWS and AIS. CWS values in the BMI, lipid metabolism, and skin toxicity domains were significantly lower in the avacopan group than the prednisone group at 26 weeks. No domain favoured the prednisone group for glucocorticoid toxicity reduction. 280 (91%) of 307 patients had glucocorticoid toxicity at 26 weeks. Blood pressure (35% in the avacopan group vs 25% in the prednisone group), infection (22% vs 24%), and lipid metabolism (20% vs 15%) contributed the most weight toward CWS values at 26 weeks. 128 (42%) of 307 patients had combinations of improvement and worsening in different domains at 26 weeks. INTERPRETATION Replacing a standard prednisone taper with avacopan in patients with ANCA-associated vasculitis reduced glucocorticoid toxicity in multiple GTI domains. For individual patients, glucocorticoid toxicity was often nuanced, improving in some domains while worsening in others. These findings emphasise the value of a composite measure of glucocorticoid toxicity that quantifies cumulative worsening and aggregate change directly. FUNDING ChemoCentryx.

Abstract
Malignant or accelerated hypertension is the most severe form of hypertension, defined clinically by very high blood pressure (diastolic above 130 mm Hg) accompanied by bilateral retinal hemorrhages and/or exudates, with or without papilledema. The aim of this review is to discuss if malignant hypertension still poses a clinically relevant entity and to highlight the diagnostic challenges of this form of hypertension. The substantial improvement in prognosis in patients with malignant hypertension over the last decades is well documented, but there is no strong evidence to suggest a significant change in its incidence. In fact, with the growing population and improving life expectancy, malignant hypertension is likely to become even more prevalent worldwide, especially in the developing countries with less advanced health care services. Despite simple diagnostic criteria of malignant hypertension, the diagnoses may be difficult in many patients. Malignant hypertension patients often have the diagnosis established only when the target organ damage occur. Furthermore, retrospective diagnosis is problematic, as malignant hypertensive retinopathy gradually resolves over a relatively short period of time, while persistent target organ damage will, however, lead to the development of complications and much poorer prognosis than in nonmalignant hypertension patients. Certainly, malignant hypertension still poses a clinically relevant and challenging form of hypertension and its possibility should be always considered during the assessment of patients with poorly controlled hypertension.

Abstract
The incidence of opportunistic infections and tumours in HIV-infected patients has sharply declined in the HAART era. At the same time there has been a growing increase of other diseases not directly linked to immunodeficiency. Renal diseases are an increasing cause of morbidity and mortality among HIV-infected patients. In the general population, chronic renal failure has considerable multiorgan repercussions that have particular implications in patients with HIV infection. The detection of occult or subclinical chronic kidney disease is crucial since effective measures for delaying progression exist. Furthermore, the deterioration in glomerular filtration should prompt clinicians to adjust doses of some antiretroviral agents and other drugs used for treating associated comorbidities. Suppression of viral replication, strict control of blood pressure, dyslipidemia and diabetes mellitus, and avoidance of nephrotoxic drugs in certain patients are fundamental components of programs aimed to prevent renal damage and delaying progression of chronic kidney disease in patients with HIV. Renal transplantation and dialysis have also special implications in HIV-infected patients. In this article, we summarise the updated clinical practice guidelines for the evaluation, management and prevention of renal diseases in HIV-infected patients from a panel of experts in HIV and nephrologists on behalf of the Spanish AIDS Study Group (GESIDA) and the National AIDS Plan.
