Key clinical point: Perioperative use of Janus kinase inhibitors (JAKi) seemed safe in patients with rheumatoid arthritis (RA) undergoing orthopedic procedures; however, the benefits of withholding JAKi to prevent postoperative complications should be balanced against the risk for a flare-up in disease activity.

Major finding: Overall, 20 patients undergoing 31 orthopedic procedures continued JAKi perioperatively, whereas 16 patients undergoing 18 procedures discontinued JAKi perioperatively by ≥1 dose for various reasons. No surgical site infections were reported during ≥90 days of follow-up. Disease flare-up was observed in 2 patients who discontinued JAKi for 3 and 14 days, respectively; however, those who discontinued JAKi for ≤1 day showed no flare-up.

Study details: This retrospective study included 32 patients with RA who had disease under control with JAKi and underwent a total of 49 orthopedic procedures.

Disclosures: This study did not receive any funding, grants, or other support. K Nishida declared receiving research grants or speaker fees from various sources.

Men who illicitly used anabolic-androgenic steroids to bulk up and then turned to illegal, web-based regimens for treating their steroid withdrawal complications have provided important clues for new approaches to treating a growing worldwide population of men who abuse steroids.

A retrospective, observational study at one steroid addiction center in Glasgow examined 641 men who had stopped using steroids within the prior 3 years in 2015-2022 and who had self-administered certain agents, collectively known as post-cycle therapy (PCT) – within 3 months of stopping steroids.

They had a significant 3.8-fold increased rate of normalization of their levels of testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH), compared with men who either never used PCT or began it more than 3 months after stopping steroids, Channa N. Jayasena, PhD, MRCP, FRCPath, reported at the annual meeting of the Endocrine Society.

These testosterone, LH, and FSH levels served as a “surrogate marker of biochemical recovery from hypogonadism,” he explained. Normalization also occurred “slightly sooner” in men who began using PCT early after steroid cessation, added Dr. Jayasena, a reproductive endocrinologist at Imperial College, London.

When men recovered their endogenous testosterone-producing capacity, it occurred after an average of about 13 weeks on PCT and after an average of about 19 weeks without PCT, a significant difference.

“There is a vacuum of medical advice on what to do” when men stop taking steroids, said Dr. Jayasena during a press briefing at the meeting. “We can’t recommend anything yet because [our studies] have not proven causality” between the post-cycle therapy that many men start after stopping steroids and any symptom improvement they experience.”

The next step is to test the PCT agents in a prospective, controlled study, an investigation Dr. Jayasena and colleagues are eager to launch. The goal is to determine whether PCT is truly effective, the optimal doses, and whether the treatments are safe.
 

‘Incredibly sophisticated’ online community

The agents that constitute PCT include human chorionic gonadotropin (hCG, the “pregnancy hormone”), selective estrogen receptor modulators (SERMs), and aromatase inhibitors (AIs). SERMs and AIs are licensed only for use in women, the former for osteoporosis and breast cancer and the latter for breast cancer.

All of these agents, as well as others, are advertised by various illegal websites as treatments that can restore endogenous testosterone production in men whose native testosterone shut down during their steroid self-medication.

Restored testosterone resolves many of the adverse effects of steroid withdrawal such as diminished libido and erections, and depressed mood and energy.

Men buy PCT agents illegally from various websites. “There is an enormous, incredibly sophisticated community online that influences” PCT, and an “incredibly refined worldwide distribution network,” Dr. Jayasena explained.

His study included 410 men who turned to PCT after steroid cessation and 170 who did not.
 

Largest study of hormone recovery when men stop taking steroids

In a further multivariate analysis of the observational data, men who had used four or more different steroid treatments fared worse – with a significant 75% reduced rate of testosterone normalization with PCT – compared with men who had used a single steroid agent.

And men who had been on a steroid regimen for more than 6 months also fared badly – with a significant 66% reduced rate of testosterone normalization with PCT, compared with men on a steroid regimen for 3 months or less.

“This is the largest study of hormone recovery when men stop taking steroids,” Dr. Jayasena noted.

And the data “require corroboration within an interventional study to determine causality.”

“We need further studies to help doctors and other health care professionals advise men about the risks of anabolic steroid use and support those who are motivated to stop,” Dr. Jayasena said.

He cautioned that the study has several limitations: biases were potentially introduced based on recruitment and on recall by participants; clinicians drew blood specimens used to measure hormone levels at random times; and participants may have engaged in concealed drug use and used steroid and PCT agents that did not contain the substances advertised.

Nevertheless, “Our data provide primary evidence that self-administered PCT drugs may be associated with improved biochemical recovery” from steroid-induced hypogonadism, and they “may have important therapeutic implications for the future treatment of men who are motivated to stop” steroids.

The study received no commercial funding. Dr. Jayasena has received research funding from Logixx Pharma.

Restored testosterone resolves many of the adverse effects of steroid withdrawal such as diminished libido and erections, and depressed mood and energy.

Men buy PCT agents illegally from various websites. “There is an enormous, incredibly sophisticated community online that influences” PCT, and an “incredibly refined worldwide distribution network,” Dr. Jayasena explained.

His study included 410 men who turned to PCT after steroid cessation and 170 who did not.
 

Largest study of hormone recovery when men stop taking steroids

In a further multivariate analysis of the observational data, men who had used four or more different steroid treatments fared worse – with a significant 75% reduced rate of testosterone normalization with PCT – compared with men who had used a single steroid agent.

And men who had been on a steroid regimen for more than 6 months also fared badly – with a significant 66% reduced rate of testosterone normalization with PCT, compared with men on a steroid regimen for 3 months or less.

“This is the largest study of hormone recovery when men stop taking steroids,” Dr. Jayasena noted.

And the data “require corroboration within an interventional study to determine causality.”

“We need further studies to help doctors and other health care professionals advise men about the risks of anabolic steroid use and support those who are motivated to stop,” Dr. Jayasena said.

He cautioned that the study has several limitations: biases were potentially introduced based on recruitment and on recall by participants; clinicians drew blood specimens used to measure hormone levels at random times; and participants may have engaged in concealed drug use and used steroid and PCT agents that did not contain the substances advertised.

Nevertheless, “Our data provide primary evidence that self-administered PCT drugs may be associated with improved biochemical recovery” from steroid-induced hypogonadism, and they “may have important therapeutic implications for the future treatment of men who are motivated to stop” steroids.

The study received no commercial funding. Dr. Jayasena has received research funding from Logixx Pharma.

Men who illicitly used anabolic-androgenic steroids to bulk up and then turned to illegal, web-based regimens for treating their steroid withdrawal complications have provided important clues for new approaches to treating a growing worldwide population of men who abuse steroids.

A retrospective, observational study at one steroid addiction center in Glasgow examined 641 men who had stopped using steroids within the prior 3 years in 2015-2022 and who had self-administered certain agents, collectively known as post-cycle therapy (PCT) – within 3 months of stopping steroids.

They had a significant 3.8-fold increased rate of normalization of their levels of testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH), compared with men who either never used PCT or began it more than 3 months after stopping steroids, Channa N. Jayasena, PhD, MRCP, FRCPath, reported at the annual meeting of the Endocrine Society.

These testosterone, LH, and FSH levels served as a “surrogate marker of biochemical recovery from hypogonadism,” he explained. Normalization also occurred “slightly sooner” in men who began using PCT early after steroid cessation, added Dr. Jayasena, a reproductive endocrinologist at Imperial College, London.

When men recovered their endogenous testosterone-producing capacity, it occurred after an average of about 13 weeks on PCT and after an average of about 19 weeks without PCT, a significant difference.

“There is a vacuum of medical advice on what to do” when men stop taking steroids, said Dr. Jayasena during a press briefing at the meeting. “We can’t recommend anything yet because [our studies] have not proven causality” between the post-cycle therapy that many men start after stopping steroids and any symptom improvement they experience.”

The next step is to test the PCT agents in a prospective, controlled study, an investigation Dr. Jayasena and colleagues are eager to launch. The goal is to determine whether PCT is truly effective, the optimal doses, and whether the treatments are safe.
 

‘Incredibly sophisticated’ online community

The agents that constitute PCT include human chorionic gonadotropin (hCG, the “pregnancy hormone”), selective estrogen receptor modulators (SERMs), and aromatase inhibitors (AIs). SERMs and AIs are licensed only for use in women, the former for osteoporosis and breast cancer and the latter for breast cancer.

All of these agents, as well as others, are advertised by various illegal websites as treatments that can restore endogenous testosterone production in men whose native testosterone shut down during their steroid self-medication.

Rusfertide, a first-in-class mimetic of hepcidin, shows high efficacy in the treatment of erythrocytosis polycythemia vera (PV), with substantial improvements in hematocrit levels that can potentially eliminate the need for phlebotomies that are typically required – but usually ineffective.

“The results are surprisingly positive,” said senior author Ronald Hoffman, MD, of the Icahn School of Medicine at Mount Sinai, New York, in discussing the late-breaking research at a press briefing during the European Hematology Association Hybrid Congress 2023.

“Importantly, the study met all of its efficacy endpoints, including the proportion of responders, absence of phlebotomy eligibility, and hematocrit control,” Dr. Hoffman said.

PV, a relatively common clonal myeloproliferative neoplasm, is characterized by uncontrolled erythrocytosis, or excessive production of red blood cells, increasing the risk for serious complications such as thromboembolic and cardiovascular events – the most common causes of morbidity and mortality in this blood cancer.

To treat PV, the maintenance of hematocrit levels at below 45% is critical. However, the current standard of care, therapeutic phlebotomy, with or without cytoreductive agents, falls short in maintaining those lower levels in the majority of patients, Dr. Hoffman explained.

To improve responses, rusfertide was developed as a novel, synthetic form of hepcidin, a peptide hormone that is produced by the liver and functions to maintain iron homeostasis and control the formation of red blood cells.

“This is somewhat of a paradigm shift,” said Dr. Hoffman in the press briefing. “We’re trying to use a hormone made by the liver to control excessive red blood cell production from polycythemia vera.”

For the phase 2 REVIVE study evaluating rusfertide in PV, the authors enrolled 53 patients with PV who had a high phlebotomy burden while receiving the current standard of care. The study’s criteria called for patients to have received at least three therapeutic phlebotomies in the 28 weeks prior to enrollment, with or without concurrent cytoreductive agents.

During a first part of the study, patients received subcutaneous rusfertide once weekly over 28 weeks, during which period the dose was adjusted individually to achieve control of HCT levels below 45%.

The second part was a withdrawal phase extending from weeks 29 to 41, in which patients were randomized in a blinded fashion to either continue on rusfertide (n = 26) or receive a placebo (n = 27).

The patients had a median age of 58; they were 71.7% male, and 54.7% had previously been treated with therapeutic phlebotomy alone while 45.3% received therapeutic phlebotomy plus cytoreductive agents.

Patients were considered to be responders if they met three criteria, including having HCT control without phlebotomy eligibility, no therapeutic phlebotomy, and having completed 12 weeks of treatment.

At the end of the second phase, 69.2% of patients receiving rusfertide were responders versus just 18.5% in the placebo group (P = .0003).

Notably, the improvement with rusfertide was observed among those receiving therapeutic phlebotomy alone, as well as with cytoreductive agents (both P = .02).

Compared with placebo, rusfertide provided significant improvement in measures including the maintenance of response, the absence of the need for therapeutic phlebotomy, and persistent HCT control (P < .0001 for all).

Whereas the phlebotomy-free rate with rusfertide during the dose-finding weeks of 1-17 was 76.9% and in weeks 17-29, 87.3%, the rate increased in part 2 of the study to 92.3%.

Additional symptom benefits reported with rusfertide at week 29 versus baseline in part 1 of the study included significant improvements in concentration (P = .0018), itching (P = .0054), fatigue (P = .0074), and inactivity (P = .0005).

In terms of safety, rusfertide was generally well tolerated, with 83% of treatment-emergent adverse events (TEAEs) being grade 1-2, while 17% were grade 3, and none were grade 4 or 5.

The most common TEAEs consisted of injection-site reactions, which were localized, and grade 1-2 in severity. The incidence of reactions decreased with ongoing treatment. There were only two discontinuations resulting from TEAEs.

Among a total of 70 patients who were enrolled, 52 (74.3%) have continued to receive rusfertide for at least 1 year, 32 (45.7%) for at least 1.5 years, and 10 (14.3%) for at least 2 years, indicating the long-term tolerability of rusfertide.

Further commenting, first author Marina Kremyanskaya, MD, PhD, an assistant professor of medicine, hematology, and medical oncology at the Icahn School of Medicine at Mount Sinai, added that a key benefit is rusfertide’s tolerability with combination therapies, which is important in enabling the avoidance of phlebotomies.

“Many patients on cytoreductive therapies still require phlebotomies, and they can’t tolerate a dose increase, either due to cytopenias or other adverse reactions,” she said in an interview. “So adding rusfertide allows for better control of their hematocrits on a lower dose of their respective cytoreductive drug.”

“The combination treatment thus allows for elimination of phlebotomy requirements and potentially improves their symptoms,” Dr. Kremyanskaya said, adding that “using a lower dose of cytoreductive drug such as interferon or hydroxyurea could offer a symptomatic relief to patients as well.”

Overall, she agreed that the responses are remarkably positive.

“I think this is what is so impressive about this agent – basically everybody responds,” Dr. Kremyanskaya said. “When we first started treating patients, we were so impressed, as none of the other drugs we use to treat PV, or any other hematologic malignancy, come anywhere close to this response rate.”

In commenting on the study, Claire Harrison, MD, a professor of myeloproliferative neoplasms and deputy medical director of research at Guy’s and St Thomas’ NHS Foundation Trust in London, agreed that “these data show a strong signal for effectiveness of this therapy in controlling red cell proliferation in PV without inducing iron deficiency and adding to the symptom burden of patients.”

The alternative of phlebotomy “is painful and consumes patient time and hospital resources,” she said in an interview.

Dr. Harrison noted that an earlier signal suggested squamous cell cancer might be of potential concern, but the signal “has not re-emerged [suggesting] this does indeed seem to be a safe and extremely effective therapy.”

Further commenting on the study during the press briefing, Konstanze Döhner, MD, of the University of Ulm (Germany) added that “this is exciting data.”

“For a long time, we had no therapeutic options for PV, and now the field is rapidly developing,” she said.

In ongoing research, rusfertide is currently being studied in the phase 3, placebo-controlled VERIFY randomized trial.

The study was sponsored by Protagonist Therapeutics. Dr. Hoffman reports being on the advisory board for Protagonist Therapeutics, and Dr. Kremyanskaya is a consultant for Protagonist Therapeutics. Dr. Harrison had no disclosures to report.

The Food and Drug Administration draft guidance released recently on possible contamination of tattoo ink was not concerning Whitney Donohue, 34, owner of Forget Me Not Tattoo in Billings, Mont. 

“I get our ink directly through the manufacturer – not at a store or through Amazon or eBay,” she said. “You never know if it’s going to be repackaged.”

Tattoo artists themselves, she said, regulate the quality of ink they use. 

Still, the threat is real, said Bruce Brod, MD, a clinical professor of dermatology at the University of Pennsylvania Health System. “I’ve seen several different infections from tattooing, and they are from organisms that tend to contaminate things in damp, liquid-type environments.”

The FDA released the new draft guidance aiming to reduce the use of pathogen-contaminated tattoo ink, which can cause stubborn infections that are especially hard to treat, dermatologists said.

“Tattooing involves puncturing the epidermis about 100 times per second with needles and depositing ink 1.5 to 2 millimeters below the surface of the skin, deep into the dermis,” the guidance states. “Contaminated tattoo ink can cause infections and serious injuries. Because these inks are injected, pathogens or other harmful substances in these inks can travel from the injection site through the blood and lymphatic systems to other parts of the body.”

The guidance comes as body art continues to get more popular. According to a 2019 poll, 30% of Americans had at least one tattoo – up from 21% in 2012. Forty percent of people 18-34 and 36% of those ages 35-54 had at least one tattoo. And though they are commonplace, tattoos come with medical risks that should be known beforehand, doctors said. 

Commonly reported symptoms of tattoo ink–associated infections include rashes, blisters, painful nodules, and severe abscesses. One of the most common bacteria found in contaminated tattoo ink is nontuberculous mycobacteria, which is related to the bacteria that causes tuberculosis and can be found in soil and water.

The guidance lists several unsanitary manufacturing conditions that may lead to ink contamination, including: 

• Preparing or packing of tattoo inks in facilities that are hard to sanitize, such as carpeted areas
• Ink or ink components left uncovered, especially near open air ducts
• Unsanitary mixing of tattoo inks, including with unclean utensils or containers
• Lack of appropriate attire by staff, failure to use hairnets, lab coats, aprons, gowns, masks, or gloves

“Infections will often spread along the drainage channels in the skin and create squiggly, uneven lines of big red, lumpy nodules,” Dr. Brod said. 

Between 2003 and 2023, there were 18 recalls of tattoo inks that were contaminated with various microorganisms, according to the FDA. In May 2019, the FDA issued a safety alert advising consumers, tattoo artists, and retailers to avoid using or selling certain tattoo inks contaminated with microorganisms.

Reputable ink manufacturers use a process called gamma radiation, which refers to electromagnetic radiation of high frequencies to kill microorganisms in the ink and its packaging.

Most of the trustworthy, high-quality ink manufacturers are well-known among tattoo artists, Ms. Donohue said. 

While she has seen customers with sensitive skin have allergic reactions, she has not seen someone come back with an infection in her 9 years working in the tattoo industry.

Because tattoo ink is considered a cosmetic product, there is not much regulatory oversight involved, which means the sterility and quality of ingredients vary, said Teo Soleymani, MD, an assistant clinical professor of dermatology and dermatological surgery at the UCLA David Geffen School of Medicine.

“Cosmeceuticals aren’t regulated by the FDA like prescription medication,” he said. “What we’ve seen many times is inadvertent contamination during the application process or contamination while the inks are being made.”

In years past, unclean needles spreading hepatitis and HIV were more of a concern, but those rates have dropped significantly, Dr. Soleymani said. 

The infections that have increased are from rare bacteria that exist in stagnant water. And they are injected into a part of the body that allows them to evade the immune system, he said: shallow enough that there aren’t many associated blood vessels, but not still below the layer of skin that gets sloughed off every 28 days. 

Sometimes, antibiotics alone won’t cut it, and the tattoo will require surgical removal. 

“The aesthetic you were going for has to be not only removed, but you’re left with a surgical scar,” Dr. Soleymani said. “Tattoos can be beautiful, but they can come with unwanted visitors that can cause months of misery.”

• Lack of appropriate attire by staff, failure to use hairnets, lab coats, aprons, gowns, masks, or gloves

“Infections will often spread along the drainage channels in the skin and create squiggly, uneven lines of big red, lumpy nodules,” Dr. Brod said. 

Between 2003 and 2023, there were 18 recalls of tattoo inks that were contaminated with various microorganisms, according to the FDA. In May 2019, the FDA issued a safety alert advising consumers, tattoo artists, and retailers to avoid using or selling certain tattoo inks contaminated with microorganisms.

Reputable ink manufacturers use a process called gamma radiation, which refers to electromagnetic radiation of high frequencies to kill microorganisms in the ink and its packaging.

Most of the trustworthy, high-quality ink manufacturers are well-known among tattoo artists, Ms. Donohue said. 

While she has seen customers with sensitive skin have allergic reactions, she has not seen someone come back with an infection in her 9 years working in the tattoo industry.

Because tattoo ink is considered a cosmetic product, there is not much regulatory oversight involved, which means the sterility and quality of ingredients vary, said Teo Soleymani, MD, an assistant clinical professor of dermatology and dermatological surgery at the UCLA David Geffen School of Medicine.

“Cosmeceuticals aren’t regulated by the FDA like prescription medication,” he said. “What we’ve seen many times is inadvertent contamination during the application process or contamination while the inks are being made.”

In years past, unclean needles spreading hepatitis and HIV were more of a concern, but those rates have dropped significantly, Dr. Soleymani said. 

The infections that have increased are from rare bacteria that exist in stagnant water. And they are injected into a part of the body that allows them to evade the immune system, he said: shallow enough that there aren’t many associated blood vessels, but not still below the layer of skin that gets sloughed off every 28 days. 

Sometimes, antibiotics alone won’t cut it, and the tattoo will require surgical removal. 

“The aesthetic you were going for has to be not only removed, but you’re left with a surgical scar,” Dr. Soleymani said. “Tattoos can be beautiful, but they can come with unwanted visitors that can cause months of misery.”

The Food and Drug Administration draft guidance released recently on possible contamination of tattoo ink was not concerning Whitney Donohue, 34, owner of Forget Me Not Tattoo in Billings, Mont. 

“I get our ink directly through the manufacturer – not at a store or through Amazon or eBay,” she said. “You never know if it’s going to be repackaged.”

Tattoo artists themselves, she said, regulate the quality of ink they use. 

Still, the threat is real, said Bruce Brod, MD, a clinical professor of dermatology at the University of Pennsylvania Health System. “I’ve seen several different infections from tattooing, and they are from organisms that tend to contaminate things in damp, liquid-type environments.”

The FDA released the new draft guidance aiming to reduce the use of pathogen-contaminated tattoo ink, which can cause stubborn infections that are especially hard to treat, dermatologists said.

“Tattooing involves puncturing the epidermis about 100 times per second with needles and depositing ink 1.5 to 2 millimeters below the surface of the skin, deep into the dermis,” the guidance states. “Contaminated tattoo ink can cause infections and serious injuries. Because these inks are injected, pathogens or other harmful substances in these inks can travel from the injection site through the blood and lymphatic systems to other parts of the body.”

The guidance comes as body art continues to get more popular. According to a 2019 poll, 30% of Americans had at least one tattoo – up from 21% in 2012. Forty percent of people 18-34 and 36% of those ages 35-54 had at least one tattoo. And though they are commonplace, tattoos come with medical risks that should be known beforehand, doctors said. 

Commonly reported symptoms of tattoo ink–associated infections include rashes, blisters, painful nodules, and severe abscesses. One of the most common bacteria found in contaminated tattoo ink is nontuberculous mycobacteria, which is related to the bacteria that causes tuberculosis and can be found in soil and water.

The guidance lists several unsanitary manufacturing conditions that may lead to ink contamination, including: 

• Preparing or packing of tattoo inks in facilities that are hard to sanitize, such as carpeted areas
• Ink or ink components left uncovered, especially near open air ducts
• Unsanitary mixing of tattoo inks, including with unclean utensils or containers
• Lack of appropriate attire by staff, failure to use hairnets, lab coats, aprons, gowns, masks, or gloves
