Metformin failed to present improvements in liver, muscle, or adipose tissue insulin resistance after treatment for 26 weeks in patients with 

, based on data from the Insulin in Type 1 Diabetes Managed with Metformin (INTIMET) study.

Metformin is an inexpensive and safe oral medication used as a first-line treatment for 

. Previous studies have demonstrated metformin’s capacity to alter glucose metabolism in the muscle and liver in patients with type 2 diabetes based on hyperinsulinemic-euglycemic clamp data. Additionally, existing reviews of randomized controlled trials have demonstrated metformin’s capacity to reduce total daily insulin dose, which has been interpreted as an improvement in insulin resistance.

“However, studies in type 1 diabetes using the gold-standard clamp technique to directly measure insulin resistance have only been performed in adolescents,” Jennifer Snaith, MBBS, B. Med. Sci, an endocrinologist and research fellow at the Garvan Institute of Medical Research, and colleagues wrote. “No study has employed the clamp technique to assess the effect of metformin on insulin resistance in adults with type 1 diabetes.”

INTIMET began as a cross-sectional study in adults with and without T1D, aiming to quantify insulin resistance at muscle, liver, and adipose tissue and identify biochemical and clinical features associated with muscle and liver insulin resistance. Subsequently, Snaith and colleagues conducted a 6-month randomized controlled clinical trial to test the hypothesis that, among adults with T1D, relative to placebo, the addition of metformin to insulin would decrease hepatic insulin resistance and improve other cardiometabolic measures without increasing adverse effects.

Male and female patients with T1D for ≥10 years were eligible for the trial, so long as they were between ages 20 and 55 with fasting c-peptide <0.3 nmol/L and HbA1c <9.5% (80 mmol/mol). Patients who were taking medications or who had conditions known to impact insulin sensitivity were excluded. During the trial, the team assessed insulin resistance via the 3-stage hyperinsulinemic-euglycemic clamp technique with isotope-labelled glucose. The primary outcome was the change in endogenous glucose production (EGP) during the low-dose phase of the clamp.

A total of 40 patients were enrolled in the trial; of these, 20 had T1D and 20 did not. All patients underwent basic phenotyping assessment between November 2019 and December 2021. In the T1D cohort, the mean age was 37.4 +/- 8.8 years (mean +/- standard deviation [SD]), with a T1D duration of 22.9 +/- 8.9 years. The T1D cohort also had a mean BMI of 26.3 +/- 3.8 kg/m2, a mean total daily insulin dose of 0.6 units/kg/day, and a mean HbA1c of 7.5 +/- 0.9%. Of the 20 adults without T1D, mean age was 37 +/- 8.4 years, mean BMI was 26.2 +/- 4.3 kg/m2, and mean HbA1c 5.1 +/- 0.3%.

The T1D group exhibited greater liver, adipose, and muscle insulin resistance compared to control, and participants with T1D had higher endogenous glucose production than controls (EGP; 5.9 +/- 2.2 µmol/kg fat free mass [FFM]/min and 3.6 +/- 1.7 µmol/kgFFM/min respectively; 

 = .0002) and higher non-esterified fatty acids (NEFA) in the low-dose phase (0.08 +/- 0.01 mmol/L and 0.02 +/- 0.02 mmol/L respectively; 

 = .001), which indicated impaired insulin-mediated suppression of hepatic glucose release and lipolysis, respectively.

Ultimately, 37 of 40 enrolled participants completed the study. At 26 weeks, no significant difference was found in the change in EGP between the metformin and placebo groups (mean difference 0.2 µmol/kg FFM/min; 95% CI, -0.4 to 0.8; 

 = .53). There was also no increase in hypoglycemia or episodes of ketoacidosis in either group.

“These results do not support prescribing metformin to reduce insulin resistance in adults with type 1 diabetes but suggest that metformin may reduce insulin dose via mechanisms independent of insulin resistance,” Snaith and colleagues wrote. “The potential cardiovascular benefits of insulin sparing and reducing peripheral hyperinsulinemia warrant further study.”

Metformin did not improve insulin resistance in liver, muscle, or adipose tissue in adults with type 1 diabetes (T1D) after 26 weeks, according to the INTIMET study. The study used the hyperinsulinemic-euglycemic clamp technique to measure insulin resistance, a method previously applied only in adolescents with T1D. Despite no significant changes in endogenous glucose production, metformin may reduce insulin doses through mechanisms unrelated to insulin resistance. The study suggests further investigation into metformin's potential cardiovascular benefits and its role in reducing peripheral hyperinsulinemia.

Results from the INTIMET study have shown no significant differences between metformin and placebo in liver, muscle, or adipose tissue insulin resistance.

Lingdolinurad (ABP-671) had acceptable safety and tolerability and reduced serum uric acid (sUA) in people with hyperuricemia or 

Findings from a phase 2a study evaluating ligdolinurad were presented at the 

American College of Rheumatology (ACR) Convergence 2025

, held October 24–29 in Chicago, Illinois, by Ullrich Schwertschlag, MD, PhD, FACP, Atom’s Senior Vice President of Clinical Development.

The study enrolled adult participants up to the age of 55 years without clinically significant kidney abnormalities on renal ultrasound and non-symptomatic hyperuricemia or gout, as evidence by 2 separate fasting sUA results of >7 mg/dL 24 hours apart. Participants were randomized to 5 multiple ascending oral dose groups including 1, 2, 4, 6, 12 mg of ABP-671 and placebo in a 7/2 ratio. The dose escalation dosing period started from 0.2 mg to 1 mg over a 9-day or 10-day period to mitigate any renal sUA overload and was then followed by a 7-day dosing period of ABP-671 or placebo. Investigators enrolled groups separately and conducted them sequentially.

Schwertschlag and colleagues found that treatment-emergent adverse events (TEAEs) were reported in 24 participants (53.3%), including 5 (71.4%), 4 (57.1%), 6 (85.7%), 4 (57.1%), 1 (14.3%), and 4 (40%) in the 1, 2, 4, 6, and 12 mg and placebo groups, respectively. There were no serious AEs, grade >3 TEAEs, or deaths. Notably, investigators did not observe AE incidence to be dose dependent. Participants followed a structured dose-escalation regimen before reaching their assigned target doses. In Group 1, dosing increased from 0.2 mg once daily (QD) on days 1–3 to 0.5 mg QD on days 4–10 and 1 mg QD on days 11–17. Group 2 received 0.2 mg QD on days 1–3, 0.5 mg QD on days 4–6, 1 mg QD on days 7–9, and 2 mg QD on days 10–16. Groups 3, 4, and 5 escalated to target doses of 4 mg, 6 mg, and 12 mg QD, respectively, administered from days 10–16.

The investigators found that sUA levels decreased in a dose dependent manner, with the max median decreases of sUA occurring at 3.00-9.00 hours post dose. Serum uric acid (sUA) levels declined in a clear dose-dependent manner, with the greatest median reductions observed between 3 and 9 hours postdose. Among participants with gout, maximum mean sUA decreases from baseline were 17.7% with placebo, 56.4% with 1 mg, 58.1% with 2 mg, 69.4% with 4 mg, 77.0% with 6 mg, and 79.2% with 12 mg. In participants with hyperuricemia, corresponding reductions were 19.9%, 50.1%, 64.1%, 73.2%, 81.2%, and 82.1%.

At 24 hours postdose, the proportion of participants reaching sUA thresholds <6.0 mg/dL, <5.0 mg/dL, and <4.0 mg/dL increased consistently with dose. For the 1-mg group, rates were 85.7%, 57.1%, and 14.3%, respectively; for 2 mg, 100%, 85.7%, and 14.3%; for 4 mg, 100%, 85.7%, and 14.3%; for 6 mg, 100%, 100%, and 57.1%; and for 12 mg, 100%, 100%, and 100%. No placebo recipients achieved any of these sUA thresholds.

Atom also presented phase 1 safety and pharmacokinetic data on its novel colchicine analogue ABP-745 at the ACR conference in healthy volunteers that demonstrated the drug was well-tolerated and exhibited dose proportional pharmacokinetics. Atom recently also enrolled the first patient in a multicenter Phase 2 acute gout flare trial that will compare ABP-745 with placebo and colchicine.

“The positive findings in both of these studies have contributed to successfully advancing our goal of providing meaningful relief to patients worldwide suffering from the damaging effects of chronic gout and the disease’s painful acute gout flares,” William Dongfang Shi, PhD, Founder and CEO of Atom, said.

 “Both ABP-671 and ABP-745 have the potential to give gout patients more effective and safer alternatives to existing gout therapies, which have insufficient efficacy and are often associated with serious or even life-threatening adverse effects.”

Rare Disease, Rapid Progress: FDA's HAE Approvals in 2025 Signal Changing Course

A disease often associated with delayed diagnosis and treatment, 

 has drawn significant attention in 2025. The US Food & Drug Administration (FDA) approved 3 HAE treatments in just 3 months: garadacimab-gxii (Andembry) in June, sebetralstat (Ekterly) in July, and donidalorsen (Dawnzera) in August.

“It's awesome. I love them all. It's like my children; you don't have a favorite,” Daniel Soteres, MD, PhD, from the University of Colorado Health Sciences Center, told HCPLive. “Every patient has an individual set of values, an individual health literacy. Their needs change over time. What works for a 5, 10, or 12-year-old may not work for a 16- or 18-year-old, [which] may not work for a 45-year-old. Having multiple options available for these patients is important.”

HAE, a rare genetic condition that causes recurrent, unpredictable, and potentially life-threatening swelling attacks in the face, throat, abdomen, hands, genitals, and feet, is estimated to occur in 1 in 50,000 people worldwide and 6,000 people in the United States.

The disease can be difficult to diagnose since its symptoms often overlap with other forms of angiodema. A report published in May 2025 stated that up to 90% of HAE-related deaths occur in undiagnosed patients experiencing asphyxiation.

HAE has a large burden on patients’ lives. At the 2025 American College of Allergy, Asthma, & Immunology (ACAAI) Annual Scientific Meeting in Orlando, Florida, several speakers, including Soteres, highlighted new data showing that children with HAE often face delayed or inconsistent emergency care, shaping long-term negative views of their condition.

 Another study found the burden is greater than previously recognized, with missed school and activities in childhood and continued academic underachievement and absences into adolescence.

Before June, there were 9 FDA-approved treatment options for HAE on the market, including 4 preventive and 4 attack-targeting therapies.8 Preventive therapies included berotralstat (Orladeyo; 2020), lanadelumab-flyo (Takhzyro; 2018), and C1 esterase inhibitor (human) products (Haegarda in 2017 and Cinryze in 2008), whereas treatments for acute attacks comprised conestat alfa (RUCONEST; 2014), icatibant (2011), C1 esterase inhibitor (human) (Berinert; 2009), and ecallantide (Kalbitor; 2009).

 These agents primarily work by replacing C1-INH, blocking bradykinin, or inhibiting kallikrein. Administration routes vary, with options of IV, subcutaneous, and oral. 

As of 2026, 12 FDA-approved products are available to prevent or treat HAE, enabling more personalized treatment plans. The newer therapies either act earlier in the HAE pathway, offer novel routes of administration, or leverage innovative molecular mechanisms.

“It makes me really proud,” said Raffi Tachdjian, MD, MPH, from UCLA Health. “I’ll speak on behalf of my colleagues, too, who are the specialists in HAE, that in the span of just 3 months, there were 3 new treatment modalities approved in HAE, which is mind-blowing, really, but it's really a testament to all the work that's gone into [the field] in the last two decades. If we think back 16 years ago, that’s when the launch of modern-era medicine came out for hereditary angioedema and and to think of how far we’ve come in the treatment landscape just makes my other colleagues and other specialties envious of the advances that we have made.”

 the only treatment targeting factor XIIa for prophylactic use to prevent HAE attacks in adults and children aged ≥ 12 years on June 16, 2025. This approval was awarded to CSL.

Garadacimab-gxii is the first HAE treatment to provide once-monthly dosing from day 1. Administered through a citrate-free, subcutaneous autoinjector in 15 seconds or less, it targets the top of the HAE cascade to prevent attacks. The therapy already holds approvals for treating HAE attacks in Australia, the United Kingdom, the European Union, Japan, Switzerland, and the United Arab Emirates.

The FDA’s decision relied on pivotal data from the placebo-controlled phase 3 VANGUARD trial, which evaluated garadacimab-gxii for prophylactic HAE treatment. In the study, participants received monthly subcutaneous injections of garadacimab-gxii or placebo for 6 months after an initial loading dose. Garadacimab-gxii led to 62% of treated patients remaining attack-free and produced ≥ 99% reductions in overall HAE attacks, attacks requiring on-demand therapy, and moderate or severe attacks compared with placebo. 

On July 7, 2025, KalVista Pharmaceuticals announced that the 

, the first oral, on-demand therapy for the treatment of acute attacks of HAE in adult and pediatric patients aged ≥ 12 years.

Sebetralstat, a novel plasma kallikrein inhibitor, was studied in the phase 3 KONFIDENT and KONFIDENT-S open-label extension trials, where investigators reported a median time from attack onset to treatment of 4 minutes among 19 adolescents patients, with symptom relief beginning at a median of 1.79 hours, severity decreasing by 3.53 hours, and complete resolution occurring by 15.09 hours. These results build on the topline 2024 KONFIDENT data showing a median 1.3-hour time to symptom relief across 136 patients experiencing laryngeal, abdominal, or breakthrough attacks while on prophylaxis.

The third HAE approval of 2025, Ionis Pharmaceuticals’ donidalorsen, was announced on August 21, 2025. The 

, an RNA-targeted medicine, to prevent HAE attacks in adults and children aged ≥ 12 years.

The decision followed a 2023 Orphan Drug Designation and drew on pivotal data from the phase 3 OASIS-HAE and OASISplus trials and the ongoing phase 2 OLE study, which together showed that donidalorsen, targeting prekallikrein, produced sustained reductions in HAE attacks, including a 96% mean reduction over 3 years in the OLE trial.

In OASIS-HAE, donidalorsen 80 mg every 4 or 8 weeks significantly lowered monthly attack rates by 81% and 55%, with 91% of patients on 4-week dosing achieving good disease control. OASISplus further demonstrated continued improvement after switching from other prophylactic therapies, with more than 90% attack-rate reductions and strong patient preference for donidalorsen.

Beyond these drugs, several experts addressed the same critical need for HAE: treatments indicated for children under 12 years old.

“The burden of these attacks on children has previously been considered more of [an issue beginning at] the onset of puberty—you know, 11, 12, 14, 15 years old,” Soteres said. “It turns out [that] when you talk with healthcare providers, the caregivers, and the adolescents who are helping control and manage this disease and understand this disease, the attacks actually start a lot younger, as early as 5 years old, and some reports even as young as 2…As a pediatric-trained hereditary angioedema specialist, I see a lot of adults, but I do worry about the younger ones.”

In an interview with HCPLive, Michael Manning, MD, an allergy, asthma, & immunology specialist located in Arizona, also pointed to the limited treatment options for children under 12 with HAE as a key unmet need.

“HAE is really a disease of childhood,” Manning said. “Eighty-five percent of patients develop symptoms before the age of 20.”

Experts also highlighted additional research needs, including improving treatment portability and addressing gaps for rural patients, individuals who dislike or require frequent injections, and those who prefer not to take a daily pill.

But for now, the approvals of garadacimab-gxii, sebetralstat, and donidalorsen reflect a field gaining unprecedented momentum.

“We joke a little bit that there's going to be more HAE drugs than patients out there,” Manning said. “You know that's way off, but it's nice because the more we know, and the better we get at treating this, the better we get [at] finding a medication that is going to reach that goal of total control, and things like donidalorsen really get us really close with a potentially a 6 time a year injection to control this, versus something you’re doing every 2 to 3 or 4 days initially. So [we are] making great strides, and I’m happy about it. I like the research and development and finding ways to find something that everybody is going to potentially do well with.”

Hereditary angioedema (HAE) has seen significant advancements in treatment options, with the FDA approving three new therapies in 2025: garadacimab-gxii, sebetralstat, and donidalorsen. These approvals expand the arsenal of HAE treatments, offering more personalized and effective management strategies. HAE, a rare genetic disorder causing unpredictable swelling, poses diagnostic challenges and significantly impacts patients' lives, especially children. The new treatments target different mechanisms and offer varied administration routes, enhancing patient care. Ongoing research aims to address unmet needs, particularly for children under 12 and rural patients.

Recent advancements in HAE treatments offer hope, but experts stress the need for more pediatric options and diverse therapies.

November delivered a wave of advances across asthma, COPD, and related inflammatory airway diseases, reflecting the accelerating shift toward precision medicine in respiratory care. New data showed pulmonary rehabilitation’s unexpected anti-inflammatory impact in asthma—particularly a 40% FeNO reduction among patients who began PR with high levels—while an open-label extension of tezepelumab demonstrated substantial steroid-sparing benefits, with nearly all OCS-dependent patients tapering to 5 mg or less and half discontinuing steroids entirely. The month also brought promising phase 2b results for rezpegaldesleukin, an IL-2 receptor pathway agonist that improved both atopic dermatitis and asthma control, underscoring its potential as a dual-benefit therapy for patients with overlapping disease.

Alongside these trial updates, expert discussions at CHEST 2025 and a recent 

 clinical forum highlighted the practical realities of implementing targeted therapies for asthma and COPD. Nicola Hanania, MD, MS, emphasized the growing importance of biomarkers such as blood eosinophils and FeNO in navigating an increasingly crowded biologic landscape, while Meilan Han, MD, and colleagues examined how real-world factors—including payer barriers, clinician familiarity, and multidisciplinary coordination—are shaping biologic adoption in COPD.

Check out this November 2025 pulmonology month in review for a recap of HCPLive’s coverage of the top news and research from the past few weeks:

1. Pulmonary Rehabilitation Reduces Type 2 Inflammation in High Inflammation Asthma

Pulmonary rehabilitation (PR) was shown to meaningfully reduce airway inflammation in people with asthma who began treatment with elevated FeNO, with the high-FeNO group experiencing a 40% drop in levels during the 3-week program. Improvements in asthma control and exercise capacity occurred across all baseline FeNO categories, but the anti-inflammatory effect was exclusive to those with high initial FeNO.

2. Tezepelumab Drastically Reduces OCS Use for Asthma in Open-Label Trial

Nearly all patients with severe, OCS-dependent asthma in the WAYFINDER trial were able to lower their daily steroid dose to 5 mg or less after 52 weeks of open-label tezepelumab, and half fully discontinued OCS while maintaining asthma control. These improvements were consistent across inflammatory subgroups, though the absence of a control arm makes the magnitude of benefit harder to interpret.

3. Rezpegaldesleukin Shows Strong Phase 2b Results for Atopic Dermatitis, Asthma

Rezpegaldesleukin, an IL-2 receptor pathway agonist, improved both atopic dermatitis severity and asthma control in the phase 2b REZOLVE-AD trial, with the highest dose (24 μg/kg every 2 weeks) delivering the strongest skin responses. Patients with comorbid asthma also saw meaningful improvements, including clinically significant ACQ-5 reductions in 75% of those with uncontrolled asthma at baseline.

4. The Asthma and COPD Precision Medicine Era, with Nicola A. Hanania, MD, MS

Nicola A. Hanania, MD, MS, professor of medicine and director of the Asthma Clinical Research Center at Baylor College of Medicine, discussed some of the sessions and data presentations from CHEST 2025 that speak to these latest innovations in asthma and COPD. He highlighted the expanding role of targeted therapies, the difficulties clinicians face in selecting among six asthma biologics, and the growing importance of biomarkers such as blood eosinophils and FeNO in guiding therapy.

5. Personalized COPD Treatment: Lessons from Biologic Trials and Clinical Practice

 clinical forum led by Meilan Han, MD, clinicians reviewed new biologic data alongside the evolving framework for identifying the right biologic candidates through biomarkers such as blood eosinophil counts. Faculty also discussed real-world considerations shaping the adoption of biologics, noting differing comfort levels among clinicians, the need for payer navigation, and the importance of multidisciplinary collaboration to integrate these therapies into routine COPD care.

November saw significant advancements in asthma, COPD, and related inflammatory airway diseases, emphasizing the shift toward precision medicine. Pulmonary rehabilitation showed a notable anti-inflammatory effect in asthma patients with high FeNO levels. Tezepelumab demonstrated substantial steroid-sparing benefits, allowing many patients to reduce or discontinue OCS use. Rezpegaldesleukin showed promise in improving both atopic dermatitis and asthma control. Expert discussions highlighted the importance of biomarkers and real-world factors in adopting targeted therapies for asthma and COPD, underscoring the complexities of integrating biologics into clinical practice.

November 2025 saw new data on asthma therapies and new insights from experts on continuing trends in the field.

New research has identified an association between 

 and reduced vessel length density in the deep capillary plexus (DCP) ischemia with increased instances of macular microaneurysms (MA), introducing MA count as a possible marker for systemic microvascular disease in patients with referable diabetic retinopathy (refDR).

“A heavier MA burden would signal deep capillary plexus (DCP) ischemia and track with extraocular vascular comorbidity in high-risk patients with refDR,” wrote study investigator Amani Fawzi, MD, a professor of ophthalmology at Northwestern University’s Feinberg School of Medicine, and colleagues.

 “Demonstrating such relationships could elevate MA counting from a purely ophthalmic marker of DR activity to a readily accessible proxy for an individual's broader microvascular health, enabling earlier interventions and closer collaboration between ophthalmologists and primary care providers.”

A noninvasive, depth-resolved approach to microvessel imaging, optical coherence tomography angiography (OCTA) provides particular quantitative perfusion metrics within the deep capillary plexus (DCP), the network tied to visual decline and DR complications. There has been limited exploration of these OCTA-derived macular perfusion metrics with MA counts, ultra-widefield fluorescein angiography ischemia, and CKD.

To evaluate the utility of MA count as a screening tool for systemic vascular comorbidities, Fawzi and colleagues conducted a cross-sectional study of patients who underwent multiple fovea-centered 3 × 3-mm OCTA scans (304 × 304 pixels). They calculated vessel density, vessel length density, and geometric perfusion deficits on the averaged images for the superficial capillary plexus (SCP) and DCP slabs. In the DCP, large superficial vessels were subtracted before GPD calculation to avoid projection artifacts.

OCTA imaging was captured in 83 eyes for 65 patients with refDR without diabetic macular edema (DME), and with CKD, defined as an eGFR persistently below 60 mL/min/1.73 m² for at least 3 months. While DME commonly occurs in refDR, this study excluded eyes with this condition.

Univariate linear mixed models were fitted for macular MA count with fixed effects for DR severity (moderate nonproliferative DR [NPDR], severe NPDR, or proliferative DR [PDR]), axial length, lens status (phakia or pseudophakia), diabetes type and duration, HbA1c, as well as the presence of hypertension, ischemic heart disease, CKD, cerebrovascular disease, or dyslipidemia.

Additionally, among the DCP and SCP slabs, investigators analyzed vessel density (VD-DCP/VD-SCP), vessel length density (VLD-DCP/ VLD), geometric perfusion deficits (GPD-SCP/ GPD-DCP), and nonperfusion index (NPI).1 In univariate analyses, with MA count as the dependent variable and each parameter entered as a single fixed effect, increased MA count was significantly associated with CKD, NPI, VLD-DCP, GPD-SCP, and GPD-DCP.

To further understand these associations as independent of potential confounders, Fawzi and colleagues fitted 3 multivariable large multimodal models, including VLD-DCP, GPD-SCP, or GPD-DCP.1 Upon multivariable analysis, CKD remained a significant independent predictor of higher macular MA count across all models (β ≈ 9.6–10.6; 

 ≤ 0.013). Among the OCTA metrics, only VLD-DCP remained significant (β = −2.46; 

 = 0.089) were not. Age showed a modest inverse association with MA count in the VLD-DCP model (

 = 0.049).1 In a sensitivity analysis including BMI as an additional covariate, CKD and VLD-DCP remained independently associated with MA count, whereas BMI was not significant.

In a receiver operating characteristic analysis, investigators used MA count as the predictor and CKD status as the binary outcome, demonstrating that macular MA burden had a fair discriminative ability for identifying CKD, with an area under the curve (AUC) of 0.755. The Youden index was maximized by a threshold of 14 macular MAs, yielding a sensitivity of 58.8% and a specificity of 86.4% for detecting CKD.

“Taken together, our findings highlight macular MA burden as a cross-disciplinary biomarker that encapsulates both localized deep capillary plexus ischemia and systemic microvascular injury reflected by CKD,” investigators concluded. “By combining high-resolution OCTA with UWF-FA, we demonstrate that macular MAs can stratify systemic risk within a relatively high-risk cohort."

Research has established a link between chronic kidney disease (CKD) and reduced vessel length density in the deep capillary plexus (DCP) ischemia, with increased macular microaneurysms (MA) in patients with referable diabetic retinopathy (refDR). This suggests MA count as a potential marker for systemic microvascular disease. Optical coherence tomography angiography (OCTA) was used to assess vessel density and perfusion metrics. CKD was a significant predictor of higher MA count, and MA burden showed fair discriminative ability for identifying CKD, highlighting its potential as a cross-disciplinary biomarker.
