Among an estimated 87% of people with HIV (PWH) whose condition has been diagnosed, roughly 66% have received medication. But only half are retained in care, leaving substantial risk for viral rebound and further HIV transmission.

A variety of factors contribute to falling out of care (OOC), a primary reason why a team from the Centers for Disease Control and Prevention reviewed over three decades of studies with the goal of identifying best practices for re-engagement.

The research, which was published  in the journal AIDS, underscores the need for more customized strategies, rather than a one-size-fits-all approach, especially for historically underserved communities.

“Many study participants across the studies included in this review represented communities who have the largest challenges with remaining in care,” Darrel H. Higa, PhD, MSW, lead study author and a behavioral scientist at the CDC in Atlanta, told this news organization.

For example, “Some face barriers that may limit their access to care ... including not having health insurance or being unable to pay for doctor visits or medication, HIV-related stigma, racism, homophobia, transphobia, health literacy, and a lack of providers who specialize in HIV care,” he said.

Other challenges relate to personal barriers, such as competing priorities (for example, work or childcare), substance use, mental health disorders, transportation problems, or a lack of social support.

Even with improvements that address some of these barriers, such as expanded access to health care insurance and broader provision of medical care and HIV medications through the national Ryan White program, structural challenges and social barriers persist.
 

Better versus best practices

In their analysis, the CDC team expanded the scope of prior reviews by including literature published between 2000 and 2020 and further conducted meta-analyses to assess the effectiveness of five common, non mutually exclusive interventions:

• patient navigation
• appointment help/alerts
• psychosocial support
• transportation/appointment reminders
• data-to-care HIV care outcomes (using health department surveillance data and/or patient health records to identify and re-engage OOC PWH)

The majority of the 26,154 participants in 39 included studies (incorporating 42 unique interventions) were male (71%) and Black (64%); the most common time frame for OOC was between 6 and 12 months, but some studies used a time frame of 3-4 months, and others more than 12 months.

Definitions for re-engagement and retention were likewise inconsistent across studies but most commonly involved having an HIV medical visit or viral load test record between 2 and 6 months (re-engagement), and ≥ 1 medical visits in each 6-month period a minimum of 60 days apart for a period of over 2 years (retention).

This is notable, as it points to the role played – at least in part – by the care fragmentation inherent in the United States health care system. Without national indicators or thresholds for clinical outcomes, services are unlikely to reach scale.

“You can’t expect retention in care until you have a close to seamless, less fragmented safety net in the United States,” said Mary Jane Rotheram-Borus, PhD, distinguished professor of clinical psychology and director of the Global Center for Children and Families at the Semel Institute for Neuroscience and Human Behavior at the University of California, Los Angeles. (Dr. Rotheram-Borus authored an accompanying editorial but was not involved in the study.)

Nevertheless, review findings highlighted that overall, the five interventions appeared to improve care re-engagement (odds ratio = 1.79, 95% confidence interval, 1.36-2.36), care retention (OR = 2.01; 95% CI, 1.64-2.46), and viral suppression (OR = 2.50; 95% CI, 1.87-2.24).

Overall, the five strategies were associated with optimal re-engagement and retention in care. In addition, four of them were associated with viral suppression for PWH who were OOC during the study time frame. The one exception was data-to-care, for which the evidence supporting an association with viral suppression was unclear.

Because of the similarities between patient navigation and transportation/appointment accompaniment, the researchers also compared PWH who received combined strategies to those who did not.

“The findings suggest that patient navigation services that often include helping with transportation to appointments or accompanying PWH to appointments may be more effective compared to interventions without the combination,” explained Dr. Higa, “especially for communities with the largest challenges remaining in care.”

He added that, moving forward, many of the same strategies that help re-engage out-of-care PWH may be useful for retention. These include co-locating services, outreach, mental health services, clinical care models, telemedicine, and financial incentives.

Despite its financial investments toward ending the HIV epidemic, the United States arguably still has a long way to go to improve retention and care.

Still, Dr. Rotheram-Borus underscores the silver lining.

“The breakthroughs in medication are substantial,” she said, pointing to her own research, which has shown that at least 60% of newly infected, poor, LGBTQ+ young people up to age 24 have been linked to care and are adherent enough to be virally suppressed.

For PWH who are out of care, perhaps treatment advances – including long-acting injectables – may ultimately fill in the gaps.

Dr. Higa and Dr. Rotherum-Borus report no relevant financial relationships.

Duodenal polyps are a relatively rare entity with a reported incidence of 0.3%-4.6%.¹ There are three major types of duodenal adenomas: sporadic, nonampullary duodenal adenomas (SNDAs), adenomas in familial adenomatous polyposis syndrome, and ampullary adenomas. It is important to distinguish between the different types of duodenal polyps as the management may differ depending on the etiology.

SNDAs constitute <10% of all duodenal polyps, most commonly located in the second portion of the duodenum, and up to 85% have been shown to have malignant transformation over time.² Most of the studies of SNDAs are small series, and there are no consensus guidelines for management. Villous features increase malignancy risk, thus resection of SNDAs is advised.^3-7 It has also been shown that 72% of patients with SNDAs also have colon polyps,⁸ and therefore these patients should be up to date on colonoscopy screening.

Ampullary adenomas are less common, but up to half may be associated with familial adenomatous polyposis (FAP), and some may be surveyed.⁹ However, those that are larger than 10 mm or have villous features may raise concern for malignancy with up to half harboring small foci of adenocarcinoma.^10,11 These require ERCP with ampullectomy. For the purposes of this paper, we will focus on endoscopic resection of SNDAs and ampullary adenomas.

Endoscopic mucosal resection (EMR) of duodenal polyps can be technically challenging. There are considerations specific to the duodenum: thin muscle layer, increased motility, and significant vascular supply including two major arterial supplies – the gastroduodenal artery from the celiac branch and the inferior pancreaticoduodenal artery from the superior mesenteric artery. These factors may explain higher reported rates of perforation and bleeding compared to colon EMR.

After a detailed inspection is performed to define the duodenal polyp in terms of size, location, and position relative to the ampulla, a submucosal injection is performed using a dye solution. Once adequate lift is achieved, the lesion is resected using stiff monofilament snares. If possible, resection sites are closed with hemostatic clips, although their utility in preventing delayed complications may be less than that in the colon because of increased motility causing them to become dislodged more easily. We avoid using snares larger than 2 cm given increased risk of perforation. Intraprocedural bleeding may be controlled with coagulation graspers on soft coagulation setting; using a bipolar electrocoagulation therapy or argon plasma coagulation is avoided, as these have been shown to increase rates of complications. Figure 1 provides examples of duodenal adenomas that have been resected.

The ampullectomy technique is slightly different from duodenal EMRs and carries the additional risk of pancreatitis.^12,13 In our opinion, there is low utility for submucosal injection unless there is a laterally spreading component onto the duodenal wall, as injection of the ampulla itself does not lift well and simply distorts views. Typically, both the common bile duct and the pancreatic duct are injected with contrast, and we typically perform a biliary sphincterotomy prior to ampullectomy. Based on endoscopist preference, one can also leave a guide wire in the pancreatic duct (PD) and pass the snare over it to perform resection to maintain access for a subsequent stent placement. This technique has the advantage of never losing pancreatic duct access, which can occur after resection from edema or bleeding and allows easy PD stent placement. The snare should be opened in a line corresponding to the long axis of the mound with the snare tip anchored above the apex of the papilla and snare opened and drawn down over the papilla. After resection, the PD must be stented to minimize pancreatitis risk.¹⁴ Figure 2 shows an ampullary adenoma pre and post EMR, with a PD stent.

Recurrence of duodenal adenomas, both SNDAs and ampullary, can be quite high, with reports up to 39%.^15-18 Risk factors include histology and size, but interestingly were not shown to be associated with en-bloc resection.^15,19 On the other hand, intraprocedural bleeding also occurs in up to 43% of patients and is associated with size, number of resections, and procedure time.²⁰ Per 2015 ASGE Standards of Practice, duodenal lesions warrant short follow-up at 3- to 6-month intervals given high recurrence rates, then at 6- to 12-month intervals for 2-5 years thereafter.²¹

When a duodenal polyp is detected, it is important to determine which type of adenoma it is to guide management. There are various techniques utilized to perform duodenal EMR and ampullectomy with some highlighted in this article. It is important to understand how to recognize, prevent, and manage associated adverse events, as well as to have a surveillance plan given the risk of recurrence.

After a detailed inspection is performed to define the duodenal polyp in terms of size, location, and position relative to the ampulla, a submucosal injection is performed using a dye solution. Once adequate lift is achieved, the lesion is resected using stiff monofilament snares. If possible, resection sites are closed with hemostatic clips, although their utility in preventing delayed complications may be less than that in the colon because of increased motility causing them to become dislodged more easily. We avoid using snares larger than 2 cm given increased risk of perforation. Intraprocedural bleeding may be controlled with coagulation graspers on soft coagulation setting; using a bipolar electrocoagulation therapy or argon plasma coagulation is avoided, as these have been shown to increase rates of complications. Figure 1 provides examples of duodenal adenomas that have been resected.

The ampullectomy technique is slightly different from duodenal EMRs and carries the additional risk of pancreatitis.^12,13 In our opinion, there is low utility for submucosal injection unless there is a laterally spreading component onto the duodenal wall, as injection of the ampulla itself does not lift well and simply distorts views. Typically, both the common bile duct and the pancreatic duct are injected with contrast, and we typically perform a biliary sphincterotomy prior to ampullectomy. Based on endoscopist preference, one can also leave a guide wire in the pancreatic duct (PD) and pass the snare over it to perform resection to maintain access for a subsequent stent placement. This technique has the advantage of never losing pancreatic duct access, which can occur after resection from edema or bleeding and allows easy PD stent placement. The snare should be opened in a line corresponding to the long axis of the mound with the snare tip anchored above the apex of the papilla and snare opened and drawn down over the papilla. After resection, the PD must be stented to minimize pancreatitis risk.¹⁴ Figure 2 shows an ampullary adenoma pre and post EMR, with a PD stent.

Recurrence of duodenal adenomas, both SNDAs and ampullary, can be quite high, with reports up to 39%.^15-18 Risk factors include histology and size, but interestingly were not shown to be associated with en-bloc resection.^15,19 On the other hand, intraprocedural bleeding also occurs in up to 43% of patients and is associated with size, number of resections, and procedure time.²⁰ Per 2015 ASGE Standards of Practice, duodenal lesions warrant short follow-up at 3- to 6-month intervals given high recurrence rates, then at 6- to 12-month intervals for 2-5 years thereafter.²¹

When a duodenal polyp is detected, it is important to determine which type of adenoma it is to guide management. There are various techniques utilized to perform duodenal EMR and ampullectomy with some highlighted in this article. It is important to understand how to recognize, prevent, and manage associated adverse events, as well as to have a surveillance plan given the risk of recurrence.

The Diagnosis: Cutaneous Amyloidosis

A punch biopsy confirmed the diagnosis of cutaneous amyloidosis, which is characterized by the deposition of amyloid proteins in the skin without systemic involvement. Subtypes of cutaneous amyloidosis include lichenoid, macular, and nodular amyloidosis. A mixed or biphasic amyloidosis can occur when both lichenoid and macular lesions are present.¹ Lichenoid and macular amyloidosis generally are characterized by moderate to severe pruritus. Lichenoid amyloidosis favors the shins, calves, ankles, and extensor extremities; macular amyloidosis has a predilection for the interscapular area and less frequently the upper arms, chest, and thighs.² Atypical variants also have been reported, including amyloidosis cutis dyschromica, poikilodermalike amyloidosis, and bullous amyloidosis, as well as incontinentia pigmenti–like, linear, and nevoid types.³ Macular amyloidosis has been reported to occur in association with progressive systemic sclerosis, primary biliary cirrhosis, systemic lupus erythematosus, paronychia, and multiple endocrine neoplasia type 2.²

Acanthosis nigricans typically presents on the neck and intertriginous areas as velvety hyperpigmented plaques. Confluent and reticulated papillomatosis also appears as slightly elevated papules; however, it occurs in the intermammary region in a reticulated pattern. Ichthyosis vulgaris also may occur on the lower extremities but presents with adherent large scales rather than papules. Keratosis pilaris may present on the proximal lower extremities with smaller, folliculocentric, fleshcolored to pink papules.

Treatment of cutaneous amyloidosis has long been challenging for dermatologists. The primary focus should be treatment of any underlying disease that is causing the pruritus and subsequent manipulation of skin lesions. Topical calcipotriol, phototherapy, oral cyclophosphamide, and Nd:YAG laser have demonstrated beneficial outcomes. IL-31 antibodies may be a potential future treatment.¹

Patients with locally advanced rectal cancer and tumors with deficient mismatch repair (dMMR) have shown a remarkable response to treatment with the programmed cell death-1 (PD-1) inhibitor dostarlimab (Jemperli).

Thus far, the study has involved only 12 patients, but all of them have had a clinical complete response to treatment. They continue to show no signs of cancer (during follow-up ranging from 6 to 25 months) and have not undergone surgery or had radiation and chemotherapy, which are the standard treatment approaches.  

The results were presented (Abstract 16) at the American Society of Clinical Oncology annual meeting and simultaneously published in the New England Journal of Medicine.

“In our study, the elimination of tumors after 6 months of therapy with PD-1 blockade enabled us to omit both chemoradiotherapy and surgery and to proceed with observation alone,” said the authors, led by Andrea Cercek, MD, Memorial Sloan Kettering Cancer Center, New York.

About 5%-10% of patients with rectal cancer have tumors with dMMR.

“The implications for quality of life are substantial, especially among patients in whom standard treatment would affect child-bearing potential [and] given that the incidence of rectal cancer is rising among young adults of childbearing age, the use of PD-1 blockade to eliminate the need for chemoradiotherapy and surgery may confer a particular benefit in that age group,” the authors wrote.

The results of the current study are cause for “great optimism, but such an approach cannot yet supplant our current curative treatment approach,” Dr. Hanna K. Sanoff, MD, University of North Carolina at Chapel Hill, wrote in an accompanying editorial.
 

Single-agent dostarlimab

For the study, all patients were treated with single-agent dostarlimab every 3 weeks for 6 months.

Dostarlimab is already approved by the Food and Drug Administration for use in the treatment of recurrent or advanced endometrial cancer with dMMR. Rectal cancer is an off-label use.

All patients had mismatch repair-deficient stage 2 or 3 rectal adenocarcinoma. The authors noted that these tumors respond poorly to standard chemotherapy regimens, including neoadjuvant chemotherapy. The median age of enrolled patients was 54 years and 62% were women.

For the study, investigators planned that patients who had a clinical complete response after completion of dostarlimab were to proceed to observation without undergoing either chemoradiotherapy or surgery, while those who did not have a complete response were to have received these standard treatments.

As it turned out, all 12 patients achieved a complete response and have been followed by observation alone. The median follow-up from time of enrollment to data cutoff for the 12 patients was 12 months.

“Therapeutic responses were rapid,” the authors noted, “with resolution of symptoms within 8 weeks after initiation of dostarlimab in 81% of the patients.”

To date, four patients have had 1 year of sustained clinical complete response after completion of the anti-PD-1 course.

In addition to the 12 patients documented in the study, another four patients have received at least one dose of dostarlimab and continue to receive treatment.

Adverse events occurred in most patients but none were grade 3 or higher. The most common grade 1 or 2 adverse events were rash or dermatitis, pruritus, fatigue, nausea and, in one patient, thyroid-function abnormalities.

The authors speculated that in addition to the extremely high tumor mutational burden associated with mismatch-repair deficiency, a tumor cell–extrinsic factor such as the gut microbiome may be driving the exceptionally good response to PD-1 blockade seen in this patient population.
 

Editorial commentary

In the editorial, Dr. Sanoff emphasized that the approach remains experimental and should not replace current curative treatment. She noted that cancer recurrences have been seen in other studies using both chemotherapy and immunotherapy. 

For example, with chemotherapy and radiation, those patients who achieve a clinical complete response have a better prognosis compared with those who do not, but she cautioned that “cancer regrowth occurs in 20% to 30% of such patients when the cancer is managed nonoperatively.”

Dr. Sanoff noted that recurrences were seen when this approach of PD-1 inhibition has been used for metastatic colorectal cancer with dMMR. In the KEYNOTE-177 trial with pembrolizumab (Keytruda), only 55% of patients were reported to be alive without cancer progression at 12 months, and of the patients who initially had a strong response, only 70% had an ongoing response 3 years later.

“These recurrence dynamics may (or may not) differ between immunotherapy and chemoradiotherapy and between early and late-stage disease,” Dr. Sanoff said.

“In fact, very little is known about the duration of time needed to find out whether a clinical complete response to dostarlimab equates to cure,” she added.

In addition, Dr. Sanoff warned that the decision not to pursue further treatment and to follow patients with observation alone requires very close monitoring.

The current study was conducted at a top U.S. cancer center, Memorial Sloan Kettering Cancer Center. The authors noted that the complete responses (after a minimum of 6 months of follow-up) were measured by the combination of rectal MRI, visual endoscopic inspection, and digital rectal examination.

The completeness of these responses was further supported by the absence of residual tumor on serial endoscopic biopsies and the resolution of 18F-fluorodeoxyglucose uptake on PET scans, the authors added.

In the editorial, Dr. Sanoff said that “safe nonoperative management [also] involves access to specialty care for direct intraluminal visualization and expertise in interpretation of rectal magnetic resonance imaging ... Such expertise is not available in all communities and without it, patients could miss the opportunity for curative resection if tumor regrowth occurred.”

The study was sponsored by the Simon and Eve Colin Foundation, GlaxoSmithKline, and Stand Up to Cancer, among others.

A novel approach that involves sensors, artificial intelligence, and real-time individualized lifestyle guidance from an app and live coaches led to a high rate of remission of type 2 diabetes in a new study.

Specifically, among 199 patients with type 2 diabetes in India who received the app-delivered lifestyle guidance developed by Twin Health, Mountain View, Calif., mean hemoglobin A1c dropped from 9.0% to 5.7% at 6 months.

This is “huge,” Paramesh Shamanna, MD, told a press briefing at the annual scientific sessions of the American Diabetes Association. The research was presented as three posters by the group at the meeting.

Patients were a mean age of 43 and had diabetes for a mean of 3.7 years and up to 8 years.

An “unprecedented” 84% of patients had remission of diabetes at 6 months, Dr. Shamanna, medical director at Twin Health, noted.

Diabetes remission was defined according to the 2021 joint consensus statement from the ADA and other organizations as an A1c less than 6.5% without the use of diabetes medications for at least 3 months.

Importantly, patients’ time in range (percentage of time spent in target blood glucose range) increased from 53% to 81%, Dr. Shamanna pointed out. On average, patients’ waist circumference decreased by 10 cm (3.9 inches) and their weight dropped from 79 kg (approximately 174 lb) to 68 kg (150 lb).

These results are driven by “the continuous individualized and precise guidance regarding nutrition, activity, and sleep,” Dr. Shamanna said in an interview.
 

Remission is not reversal or cure ...

“Remission” from type 2 diabetes is not “reversal” or a “cure,” Robert A. Gabbay, MD, PhD, chief scientific and medical officer of the ADA, stressed to the press. Just like cancer, diabetes can return after remission

Therefore, it is important to follow the lifestyle guidance. Patients may still be at risk for diabetes complications after diabetes remission, so it’s also important to continue to be screened for eye disease, nerve damage, and lipid levels.

However, “remission can be made to last,” Dr. Shamanna said, by continuing to follow the lifestyle advice and getting back on track after a relapse.

“We’re in a different time right now,” Lisa Shah, MD, chief medical officer, Twin Health, noted. “This is very different from management of blood glucose to a certain number.”

This study shows that “remission [from type 2 diabetes] is possible. How you achieve it can be precise for you.”

The program is designed to consider the health and happiness of the patient, added Shashank R. Joshi, MD, chief scientist, Twin Health. “We want remission to be complication free. These findings give patients hope.”

“It’s exciting now that we can really start thinking about remission as an option for people with [type 2] diabetes, and that just provides such incredible hope for all of those living with [type 2] diabetes,” Dr. Gabbay said in an interview.
 

How the intervention works

The Twin Precision Treatment (TPT) intervention integrates multiple data – glucose values from a continuous glucose monitor (CGM); heart rate, activity, and sleep time from a fitness tracker; blood pressure values from a blood pressure cuff; food intake from the patient’s food log; and weight and body fat data from a smart scale – and provides the patient with precise, individualized nutrition and health guidance.

The four most critical sensors are the CGM, the fitness tracker, the smart scale, and the blood pressure cuff, Dr. Shah explained. The system gathers thousands of signals combined with patient self-reported data including mood or anxiety.

The CGM is used to build the initial nutrition guidance during the first 30 days. Once a patient is in remission, he or she can just keep the fitness tracker and smart scale.

The coaches who are part of this program include dietitians who are trained to provide compassionate patient education and help patients avoid diabetes relapse, and they are overseen by a licensed provider.

The program does not restrict calories. “It is not a diet,” Dr. Shah stressed.

The algorithm makes mini adjustments to the food a person is already eating to improve nutrition, Dr. Joshi explained. “This is personalized medicine at its best.” Patients eat food that they like and are guided to make small changes to get glucose under control and avoid glucose spikes.

The program is designed to safely deescalate diabetes medications as A1c decreases, Dr. Shamanna added.

U.S. clinical trial, health insurance coverage

The 1-year results of the current trial are expected in August, and the trial will continue for 2-=5 years, Dr. Shamanna said.

The company has started a clinical trial in the United States, with 5-year results expected in 2027.

“Currently, in the United States, we are partnering with self-insured employers and select health plans that offer [Twin Precision Treatment ] as an available benefit for their members,” Dr. Shah said. It “is suitable for most members living with type 2 diabetes, with rare exclusion situations.”

The study was funded by Twin Health. Dr. Shamanna, Dr. Shah, and Dr. Joshi are employees of Twin Health.

A novel approach that involves sensors, artificial intelligence, and real-time individualized lifestyle guidance from an app and live coaches led to a high rate of remission of type 2 diabetes in a new study.

Specifically, among 199 patients with type 2 diabetes in India who received the app-delivered lifestyle guidance developed by Twin Health, Mountain View, Calif., mean hemoglobin A1c dropped from 9.0% to 5.7% at 6 months.

This is “huge,” Paramesh Shamanna, MD, told a press briefing at the annual scientific sessions of the American Diabetes Association. The research was presented as three posters by the group at the meeting.

Patients were a mean age of 43 and had diabetes for a mean of 3.7 years and up to 8 years.

An “unprecedented” 84% of patients had remission of diabetes at 6 months, Dr. Shamanna, medical director at Twin Health, noted.

Diabetes remission was defined according to the 2021 joint consensus statement from the ADA and other organizations as an A1c less than 6.5% without the use of diabetes medications for at least 3 months.

Importantly, patients’ time in range (percentage of time spent in target blood glucose range) increased from 53% to 81%, Dr. Shamanna pointed out. On average, patients’ waist circumference decreased by 10 cm (3.9 inches) and their weight dropped from 79 kg (approximately 174 lb) to 68 kg (150 lb).

These results are driven by “the continuous individualized and precise guidance regarding nutrition, activity, and sleep,” Dr. Shamanna said in an interview.
 

Remission is not reversal or cure ...

“Remission” from type 2 diabetes is not “reversal” or a “cure,” Robert A. Gabbay, MD, PhD, chief scientific and medical officer of the ADA, stressed to the press. Just like cancer, diabetes can return after remission

Therefore, it is important to follow the lifestyle guidance. Patients may still be at risk for diabetes complications after diabetes remission, so it’s also important to continue to be screened for eye disease, nerve damage, and lipid levels.

However, “remission can be made to last,” Dr. Shamanna said, by continuing to follow the lifestyle advice and getting back on track after a relapse.

“We’re in a different time right now,” Lisa Shah, MD, chief medical officer, Twin Health, noted. “This is very different from management of blood glucose to a certain number.”

This study shows that “remission [from type 2 diabetes] is possible. How you achieve it can be precise for you.”

The program is designed to consider the health and happiness of the patient, added Shashank R. Joshi, MD, chief scientist, Twin Health. “We want remission to be complication free. These findings give patients hope.”

“It’s exciting now that we can really start thinking about remission as an option for people with [type 2] diabetes, and that just provides such incredible hope for all of those living with [type 2] diabetes,” Dr. Gabbay said in an interview.
 

How the intervention works

The Twin Precision Treatment (TPT) intervention integrates multiple data – glucose values from a continuous glucose monitor (CGM); heart rate, activity, and sleep time from a fitness tracker; blood pressure values from a blood pressure cuff; food intake from the patient’s food log; and weight and body fat data from a smart scale – and provides the patient with precise, individualized nutrition and health guidance.

The four most critical sensors are the CGM, the fitness tracker, the smart scale, and the blood pressure cuff, Dr. Shah explained. The system gathers thousands of signals combined with patient self-reported data including mood or anxiety.

The CGM is used to build the initial nutrition guidance during the first 30 days. Once a patient is in remission, he or she can just keep the fitness tracker and smart scale.

The coaches who are part of this program include dietitians who are trained to provide compassionate patient education and help patients avoid diabetes relapse, and they are overseen by a licensed provider.

The program does not restrict calories. “It is not a diet,” Dr. Shah stressed.

The algorithm makes mini adjustments to the food a person is already eating to improve nutrition, Dr. Joshi explained. “This is personalized medicine at its best.” Patients eat food that they like and are guided to make small changes to get glucose under control and avoid glucose spikes.

The program is designed to safely deescalate diabetes medications as A1c decreases, Dr. Shamanna added.

In patients with uncontrolled gout, response rates were increased by 32% when methotrexate was used in conjunction with pegloticase versus pegloticase plus a placebo, it was reported at the annual European Congress of Rheumatology.

In the phase 4 MIRROR trial, 71% of patients who received pretreatment with methotrexate and then the combination of methotrexate and pegloticase achieved uric-acid levels lower than 6 mg/dL for more than 80% of the time during weeks 20-24 of the 52-week study. By comparison, only 39% of those treated with pegloticase plus a placebo achieved this primary endpoint (P < .0001).

This is good news for patients, suggested two rheumatologists who were not involved in the study. The combination appears “useful for a select group of gout patients,” observed Christian Ammitzbøll, MD, PhD, from Aarhus University Hospital, Denmark.

“Very promising in refractory gout,” agreed Emre Bilgin, MD, from Ankara, Turkey.
 

Rationale for using methotrexate

“Oral urate lowering agents are the mainstay of treatment of gout, but there are patients that just don’t respond to oral agents,” said Dr. Botson, a rheumatologist in private practice from Anchorage, Alaska.

“These patients are very difficult to treat,” he added. “They have a lot of physical disabilities, they have high medical comorbidities, and they have a low quality of life. Their treatment options are extremely limited.”

One of the few options they have is pegloticase, a pegylated uric acid specific enzyme sold under the brand name Krystexxa for the past 12 years. It lowers serum uric acid by converting it to allantoin, which is more water soluble and thus is easier to excrete from the body.

However, one of the problems of using the drug is that anti-drug antibodies frequently develop, meaning that discontinuation rates can be as high as 50%, with around a quarter of patients at high risk of experiencing an infusion reaction.

“Methotrexate is a medication we’re very familiar with for other rheumatologic conditions that use biologic medications, and we use this to prevent anti-drug antibodies. So, the MIRROR RCT was a study we performed to examine the pegloticase therapy in combination with methotrexate co therapy,” explained Dr. Botson.

In fact, co-administration of methotrexate and pegloticase was associated with fewer infusion reactions than using pegloticase alone (3% vs. 31%).
 

Study design and results

A total of 152 patients were included in the trial and were treated with methotrexate at a weekly dose of 15 mg for 2 weeks before being randomized, 2:1, to either continue methotrexate and then receive intravenous pegloticase or receive the latter with a placebo. Pegloticase was given at a dose of 8 mg every 2 weeks. Treatment was for 52 weeks, with the primary endpoint of serum uric acid response tested at 6 months.

The reason for the 2-week run-in period with methotrexate was to check that patients would be able to tolerate it, Dr. Botson explained.

The mean age of patients was around 54 years, the majority (> 84%) were male and were White (69%). The average duration of gout was about 14 years, with over 74% having tophi present at screening and experiencing 10-11 flares in the previous year. Baseline serum uric acid averaged at about 9 mg/dL.

Almost three-quarters of the 100 patients (73%) who were treated with the combination completed treatment to week 24 while the corresponding percentage in the placebo arm (n = 52) was 39%. The main reason for stopping was due to lack of efficacy (27% and 61% of cases, respectively), defined as having serum uric acid levels above 6 mg/dL on two consecutive measurements.

The median time to discontinuation was 69 days for those in the placebo arm; “it was non-estimable” in the methotrexate arm, Dr. Botson reported.

The mean change in serum uric acid through to week 24 was higher in the methotrexate than placebo arm, at a respective 7.66 and 5.23 mg/dL, giving a significant mean difference of 2.43 mg/dL.

There was a “dramatic resolution of tophaceous deposits,” Dr. Botson said. Complete resolution of tophi was seen in 34.6% of methotrexate-treated patients versus 13.8% of pegloticase-placebo–treated patients (P = .043).

One of the most common adverse events associated with pegloticase treatment is gout flare, which occurred in about 70% of participants in both study arms. Overall, the addition of methotrexate did not increase the risk for adverse events in general, and of the two deaths seen in the study – both in methotrexate-treated patients – one was because of a heart attack and another due COVID-19, so they were unrelated to study treatment.

In patients with renal insufficiency

Concern was raised during the discussion, however, on how to handle methotrexate use in patients with renal insufficiency.

“That’s been a debate that we’ve had in this study and others,” said Dr. Botson, acknowledging that “methotrexate is often a concern for the nephrologist that we’re co-treating these patients with.” However, no dose adjustments were needed in the study.

“There are some other studies with other immunomodulators that do suggest that other agents could be used that may be a little less potentially renal toxic, but we didn’t see any toxicity in the patients that we had, even in those that had a reduced [glomerular filtration rate],” he added.

Dr. Botson has received research support from Horizon and Radius Health. He also acknowledged receiving speakers fees from AbbVie, Amgen, Aurinia, ChemoCentryx*, Horizon, Eli Lilly, and Novartis.

NATIONAL HARBOR, MD. – While patients with multiple sclerosis (MS) don’t seem to be more likely to be infected with COVID-19, a neurologist told colleagues, the jury is still out over whether they face a higher mortality risk, especially if they take certain disease-modifying therapies (DMTs)

In regard to MS overall, “the data is conflicting, but any increased risk of mortality appears to be slight. And it appears to be chiefly the consequences associated with comorbidities as seen in other populations,” Joseph R. Berger, MD, said at the John F. Kurtzke Memorial Lecture at the annual meeting of the Consortium of Multiple Sclerosis Centers. “If you’re old, if you’re infirm, if you have obesity and cardiovascular disease and underlying pulmonary disease, you’re at risk of dying yourself. It’s not so much the MS,” said Dr. Berger, professor of neurology at the Hospital of the University of Pennsylvania and chief of the multiple sclerosis division at the University of Pennsylvania, Philadelphia.

Dr. Berger had his own COVID-19 story to tell: He couldn’t attend the conference in person because he was quarantining in Portugal since he tested positive. At press time, he was faring well but had reported 4 days of intense back pain.

In regard to MS and COVID-19, Dr. Berger said consistent research suggests that patients with MS aren’t at higher risk of COVID infection, although hospitalization may be more common. There may be a very small increase in risk of MS relapse in patients with COVID-19, he said, but pseudorelapses are far more common. As for mortality, he highlighted a 2021 pooled analysis of 18 studies with 5,634 patients that suggested they had a crude death rate of 1.97%, standardized lethality ratio of 1.24, and a 24% increased risk of death.

Dr. Berger is skeptical of these findings, however, in light of overall death rate numbers. Early on in the pandemic, the fatality rate in China was estimated at 2.3%.

He said he’s more convinced by a retrospective 2021 German COVID-19 study that compared 551 patients with MS to 156,973 other patients and found lower rates of ICU admission (17.1% in patients with MS vs. 22.7% in those without it), ventilation (9.8% vs. 14.5%), and in‐hospital mortality (11.1% vs. 19.3%).

Meanwhile, a 2021 systematic review found no increase in mortality among 4,310 patients with MS (3% death rate, 20.7% hospitalization), but the death risk was highest among those on no DMTs and those taking anti-CD20 monoclonal antibodies. The COViMS Registry has reported similar findings regarding the anti-CD20 drugs rituximab and ocrelizumab, Dr. Berger noted, and a pooled study of Italian and French data links the monoclonal antibodies to more severe COVID. A 2021 aggregated study also linked the antibodies to increased risk of hospitalization and ICU admission.

“Anti-CD20 monoclonal antibodies appear to increase the risk of hospitalization and perhaps the acquisition of the virus, ICU admission, maybe death,” he said, with rituximab appearing to pose the most risk, followed by ocrelizumab and ofatumumab. “And it appears that the platform [older] therapies may be associated with lesser mortality.”

As for nondrug factors, Dr. Berger said, studies have linked higher risk to age, male sex, and comorbidities.

COVID-19 vaccines are another area of concern, he said. “The recommendation is to administer vaccination prior to the initiation of the anti-CD20s, alemtuzumab, and cladribine, and wait a period of time. Three months is ideal, maybe a little longer, because it appears that the antibody response seems to be best as your CD19 count starts to return.”

Finally, Dr. Berger noted that “passive vaccination” is now available via Evusheld (tixagevimab and cilgavimab) as a preexposure treatment for people with moderate to severe immune compromise who may not mount an effective immune response to COVID-19 vaccination or those who are allergic.

Dr. Berger reported multiple disclosures.

As for mortality, he highlighted a 2021 pooled analysis of 18 studies with 5,634 patients that suggested they had a crude death rate of 1.97%, standardized lethality ratio of 1.24, and a 24% increased risk of death.

Dr. Berger is skeptical of these findings, however, in light of overall death rate numbers. Early on in the pandemic, the fatality rate in China was estimated at 2.3%.

He said he’s more convinced by a retrospective 2021 German COVID-19 study that compared 551 patients with MS to 156,973 other patients and found lower rates of ICU admission (17.1% in patients with MS vs. 22.7% in those without it), ventilation (9.8% vs. 14.5%), and in‐hospital mortality (11.1% vs. 19.3%).

Meanwhile, a 2021 systematic review found no increase in mortality among 4,310 patients with MS (3% death rate, 20.7% hospitalization), but the death risk was highest among those on no DMTs and those taking anti-CD20 monoclonal antibodies. The COViMS Registry has reported similar findings regarding the anti-CD20 drugs rituximab and ocrelizumab, Dr. Berger noted, and a pooled study of Italian and French data links the monoclonal antibodies to more severe COVID. A 2021 aggregated study also linked the antibodies to increased risk of hospitalization and ICU admission.

“Anti-CD20 monoclonal antibodies appear to increase the risk of hospitalization and perhaps the acquisition of the virus, ICU admission, maybe death,” he said, with rituximab appearing to pose the most risk, followed by ocrelizumab and ofatumumab. “And it appears that the platform [older] therapies may be associated with lesser mortality.”

As for nondrug factors, Dr. Berger said, studies have linked higher risk to age, male sex, and comorbidities.

COVID-19 vaccines are another area of concern, he said. “The recommendation is to administer vaccination prior to the initiation of the anti-CD20s, alemtuzumab, and cladribine, and wait a period of time. Three months is ideal, maybe a little longer, because it appears that the antibody response seems to be best as your CD19 count starts to return.”

Finally, Dr. Berger noted that “passive vaccination” is now available via Evusheld (tixagevimab and cilgavimab) as a preexposure treatment for people with moderate to severe immune compromise who may not mount an effective immune response to COVID-19 vaccination or those who are allergic.

NATIONAL HARBOR, MD. – While patients with multiple sclerosis (MS) don’t seem to be more likely to be infected with COVID-19, a neurologist told colleagues, the jury is still out over whether they face a higher mortality risk, especially if they take certain disease-modifying therapies (DMTs)

In regard to MS overall, “the data is conflicting, but any increased risk of mortality appears to be slight. And it appears to be chiefly the consequences associated with comorbidities as seen in other populations,” Joseph R. Berger, MD, said at the John F. Kurtzke Memorial Lecture at the annual meeting of the Consortium of Multiple Sclerosis Centers. “If you’re old, if you’re infirm, if you have obesity and cardiovascular disease and underlying pulmonary disease, you’re at risk of dying yourself. It’s not so much the MS,” said Dr. Berger, professor of neurology at the Hospital of the University of Pennsylvania and chief of the multiple sclerosis division at the University of Pennsylvania, Philadelphia.

Dr. Berger had his own COVID-19 story to tell: He couldn’t attend the conference in person because he was quarantining in Portugal since he tested positive. At press time, he was faring well but had reported 4 days of intense back pain.

CHICAGO – In a large case series of metastatic breast cancer patients with pseudocirrhosis, researchers found that almost all such patients had hormone receptor–positive (HR+) disease as well as extensive liver metastases. Pseudocirrhosis appears radiographically similar to cirrhosis, but lacks its classic pathologic features.

The study is the largest cohort of patients with pseudocirrhosis studied to date. “It provides important clinical information about the natural history of this condition to help oncologists better understand which patients develop this condition and what complications are most common. Interestingly, we found that patients who developed ascites had a worse overall survival than patients who did not develop ascites, which was not previously reported,” said Laura Huppert, MD, who presented the findings during a poster session at the annual meeting of the American Society of Clinical Oncology.

Pseudocirrhosis is commonly found in patients with metastatic breast cancer and can lead to ascites and varices, among other complications. “These problems can be quite debilitating and even life-threatening for our patients. In order to better diagnose and treat our patients with pseudocirrhosis, we first wanted to understand the natural history of this condition, including which patients develop it, what treatments they have received, and what complications are most frequent,” said Dr. Huppert, MD, who is a hematology/oncology fellow at the University of California, San Francisco.

The study was retrospective, making it impossible to determine causality. “It is possible that the biology of HR+ disease predisposes patients to the development of pseudocirrhosis through mechanisms that are not yet elucidated. Alternatively, this may be due to the fact that patients with HR+ disease tend to have longer survival and are on systemic therapy for longer periods of time, allowing more time for pseudocirrhosis to develop in response to systemic therapy,” Dr. Huppert said.

In future work, Dr. Huppert plans to examine a control arm of patients with liver disease who do not develop pseudocirrhosis to gain a better understanding of factors that might cause the condition. She also hopes to work with hepatologists to determine if new antifibrosis agents might be applicable to pseudocirrhosis. “There may be interesting things we can learn from other disease states and apply to this condition,” she said.

The researchers analyzed data from 120 patients with pseudocirrhosis. 82.5% of patients were HR+/HER2–, 11.7% were HR+/HER2+, 2.5% were HR–/HER2+, and 3.3% were triple negative. Liver metastases were present in all patients, and 82.5% had more than 15 liver lesions.

A total of 92.5% of patients had previously undergone chemotherapy before pseudocirrhosis was identified, and the median time to diagnosis of pseudocirrhosis after diagnosis of liver metastases was 18.7 months. 50% of patients with pseudocirrhosis had stable or responding disease. After pseudocirrhosis diagnosis, patients underwent a median of 1.0 additional lines of therapy, and the median overall survival following pseudocirrhosis diagnosis was 7.9 months. A total of 80.8% of patients went on to be diagnosed with ascites, 17.5% with esophageal varices, 21.7% with splenomegaly, 10.0% with gastrointestinal bleeding, and 9.2% with hepatic encephalopathy.

Patients with radiographic evidence of ascites survived an average of 42.8 months after metastatic breast cancer diagnosis, while those without ascites survived an average of 76.2 months (P < .001).

Specialty care was rare: Just 7.5% of patients received a GI/hepatology consultation.

Dr. Huppert has no relevant financial disclosures.

A new study shows that being overweight may offer some women undergoing treatment for breast cancer protection against neutropenia – a potentially deadly outcome that can occur as a result of chemotherapy treatment.

The study was presented at the annual meeting of the American Society of Clinical Oncology.

It is known that body mass index can affect breast cancer risk and prognosis, but it is not known if BMI can affect how well endocrine therapy works in a given patient. In the PALLAS clinical trial, Georg Pfeiler, MD, Medical University of Vienna, and colleagues, conducted an analysis of 5,698 patients with early hormone receptor–positive breast cancer receiving endocrine therapy with or without palbociclib. Dr. Pfeiler found that women who are overweight or obese had significantly less frequent and less severe cases of neutropenia. With fewer or less severe cases of neutropenia, there were also fewer interruptions in palbociclib treatment.

“One explanation for the lower discontinuation rates may be that the distributional volume of the drug is higher in overweight and obese patients leading to lower serum drug concentrations. It could also be influenced by differences in pharmacokinetics with respect to hyperinsulinemia,” said Dr. Pfeiler, who leads the Oncological Breast Outpatient Clinic and Bone Health Outpatient Clinic at the Medical University of Vienna.

The PALLAS trial compared the combination of palbociclib and adjuvant endocrine therapy with endocrine therapy alone in 5,698 women with early breast cancer. Patients were categorized according to BMI as underweight (BMI < 18.5 kg/m2), normal weight (BMI 18.5-24.9), overweight (BMI, 25-29.9), and obese (> 30). The investigators analyzed differences in adverse events, time to early discontinuation of palbociclib, and in time to invasive disease-free survival.

At baseline, of 5,698 patients, 68 (1.2%) were underweight, 2,082 (36.5%) were of normal weight, 1,818 (31.9%) were overweight, and, 1,730 (30.4%) were obese. In patients treated with palbociclib, neutropenia was the primary toxicity leading to treatment discontinuation with rates of 21.1% in normal-weight patients, 14.0% of overweight patients, and 5.9% of obese patients, respectively.

Significantly different rates of all-grade neutropenia were observed in normal weight, overweight, and obese participants with regard to total (88.5%, 85.7% and 74.7%), as well as grade 3 (64.1%, 62.0% and 43.9%) and grade 4 neutropenia (7.0%, 3.6% and 2.0%), respectively. The lower frequency and severity of neutropenia observed in overweight and obese patients was associated with a significantly lower treatment discontinuation rate over time when compared with normal-weight patients (overweight vs. normal weight: HR, 0.73; 95% CI 0.63-0.84; P < .0001, and obese vs. normal weight: HR, 0.65; 95% CI, 0.56-0.75; P < .0001). There was, however, despite these observations, no statistically significant improvement in invasive disease survival with the addition of palbociclib to endocrine therapy in any weight category (normal weight: HR, 0.84; 95% CI 0.63-1.12; overweight: HR, 1.10; 95% CI 0.82-1.49; and obese: HR, 0.95; 95% CI, 0.69-1.30).

“This is an early analysis, and should be interpreted with caution, especially with regard to disease outcomes. The findings may reduce concerns over hematologic side effects in the overweight and obese. In the future there may be an important impact if it turns out after longer-term follow-up that palbociclib has been underdosed in the overweight and obese. We may need BMI-adapted dose management,” said Dr. Pfeiler, who is currently working on a longer-term follow-up study of the PALLAS group.

The analysis found no significant correlation between weight and occurrence of invasive disease events.

Dr. Pfeiler disclosed honoraria and grants from Pfizer. The study was funded by Alliance Foundation Trials.

When a patient first presents to a doctor with signs and symptoms of having breast cancer that has metastasized to other parts of the body, the prospects of long-term survival are dim. But now, a new study presented at the annual meeting of the American Society of Clinical Oncology suggests that women with metastatic HER2+ breast cancer are generally living longer, compared with women treated in previous years.

Between 2010 and 2018, the overall survival for 5,576 women (99% women) with HER2+ metastatic breast cancer enrolled in this study improved 5.6% each year of the study. The study also showed a 6.4% improvement in breast cancer–specific death rates year over year.

“These highlights coincide with significant therapeutic advances for HER2+ metastatic breast cancer over the past decade. We need to continue our research efforts to identify better treatments for our patients so we can continue to improve the prognosis of these patients,” said study author Jose Pablo Leone, MD, a medical oncologist with Dana-Farber Cancer Institute, Boston.

The study, which is based on an evaluation of data from the Surveillance, Epidemiology and End Results database, found factors associated with shorter survival included older age, Black race, lower income, and the presence of visceral or brain metastases. Long-term survival of more than 5 years was associated with younger age, White race, and higher income, but also having fewer metastatic sites and estrogen receptor (ER)/progesterone receptor (PR) positivity.

“We also found specific factors that were only associated with shorter overall survival, such as the presence of metastases in the brain, liver, or lung. The lack of metastasis in these sites was not associated with longer overall survival. In contrast, a lower number of metastatic sites, regardless of the location of those sites were associated with longer overall survival but not short-term survival,” Dr. Leone said.

A total of 63.3% of patients in the study survived less than 2 years while 37.8% lived 5 years or more, and 26.8% lived longer than 8 years. Factors associated with less than 2 years in overall survival were older age (odds ratio, 3.76), Black race (OR 1.5), nonductal nonlobular (OR, 4.64), brain metastases (OR, 2.95), liver metastases (OR, 1.98), lung metastases (OR, 1.56), ER/PR negativity (OR, 1.74), and lower income (OR, 1.62). Factors associated with longer survival of 5 years or more included younger age (OR, 2.85), White race (OR, 1.7), fewer metastatic organ sites (OR, 2.6), ER/PR positivity (OR, 1.27), and higher income (OR, 3.31).

Dr. Leone said that, while involvement of specific visceral sites (brain, liver, lung) was associated with shorter overall survival, the odds of living longer than 5 years was not associated with those sites. In contrast, the number of sites was associated with longer overall survival, but not shorter overall survival regardless of location. “While fewer number of metastatic sites were associated with higher odds of overall survival greater than 5 years, the number of metastatic sites was not associated with the odds of overall survival of being less than 2 years,” he said.

A limitation of the study included the retrospective nature of the study. “Treatment data are unavailable, so we cannot quantify the impact of various treatments on the odds of survival,” Dr. Leone said.

This study was not funded.

Between 2010 and 2018, the overall survival for 5,576 women (99% women) with HER2+ metastatic breast cancer enrolled in this study improved 5.6% each year of the study. The study also showed a 6.4% improvement in breast cancer–specific death rates year over year.

“These highlights coincide with significant therapeutic advances for HER2+ metastatic breast cancer over the past decade. We need to continue our research efforts to identify better treatments for our patients so we can continue to improve the prognosis of these patients,” said study author Jose Pablo Leone, MD, a medical oncologist with Dana-Farber Cancer Institute, Boston.

The study, which is based on an evaluation of data from the Surveillance, Epidemiology and End Results database, found factors associated with shorter survival included older age, Black race, lower income, and the presence of visceral or brain metastases. Long-term survival of more than 5 years was associated with younger age, White race, and higher income, but also having fewer metastatic sites and estrogen receptor (ER)/progesterone receptor (PR) positivity.

“We also found specific factors that were only associated with shorter overall survival, such as the presence of metastases in the brain, liver, or lung. The lack of metastasis in these sites was not associated with longer overall survival. In contrast, a lower number of metastatic sites, regardless of the location of those sites were associated with longer overall survival but not short-term survival,” Dr. Leone said.

A total of 63.3% of patients in the study survived less than 2 years while 37.8% lived 5 years or more, and 26.8% lived longer than 8 years. Factors associated with less than 2 years in overall survival were older age (odds ratio, 3.76), Black race (OR 1.5), nonductal nonlobular (OR, 4.64), brain metastases (OR, 2.95), liver metastases (OR, 1.98), lung metastases (OR, 1.56), ER/PR negativity (OR, 1.74), and lower income (OR, 1.62). Factors associated with longer survival of 5 years or more included younger age (OR, 2.85), White race (OR, 1.7), fewer metastatic organ sites (OR, 2.6), ER/PR positivity (OR, 1.27), and higher income (OR, 3.31).

Dr. Leone said that, while involvement of specific visceral sites (brain, liver, lung) was associated with shorter overall survival, the odds of living longer than 5 years was not associated with those sites. In contrast, the number of sites was associated with longer overall survival, but not shorter overall survival regardless of location. “While fewer number of metastatic sites were associated with higher odds of overall survival greater than 5 years, the number of metastatic sites was not associated with the odds of overall survival of being less than 2 years,” he said.

A limitation of the study included the retrospective nature of the study. “Treatment data are unavailable, so we cannot quantify the impact of various treatments on the odds of survival,” Dr. Leone said.

This study was not funded.
