MILAN – Skin manifestations of the vasculitides can point the way to an accurate diagnosis and provide clues about disease severity, Robert Micheletti, MD, said at the World Congress of Dermatology.

In granulomatous vasculitis, histiocytes and giant cells can play a significant role, explained Dr. Micheletti, director of the cutaneous vasculitis clinic at the University of Pennsylvania, Philadelphia. The condition may be secondary to an autoimmune disease such as lupus erythematosus or RA; a granulomatous disease such as Crohn’s disease or sarcoidosis; infections such as tuberculosis, a fungal disease, or herpes or zoster viruses, or lymphoma, Dr. Micheletti said.

However, a primary systemic vasculitis such as granulomatosis with polyangiitis (GPA; formerly known as Wegener’s polyangiitis) or eosinophilic granulomatosis with polyangiitis (EGPA; also known as Churg-Strauss vasculitis), giant cell arteritis, or Takayasu arteritis may also be responsible, he said. Occasionally, the culprit can also be a drug-induced vasculitis.

The physical examination gives clues to the size of involved vessels, which in turn helps to classify the vasculitis, Dr. Micheletti said.

When vasculitis affects small vessels, the skin findings will be palpable purpura, urticarial papules, vesicles, and petechiae, he said, adding that “The small vessel involvement accounts for the small size of the lesions, and complement cascade and inflammation account for the palpability of the lesions and the symptomatology.” As red blood cells extravasate from the affected vessels, nonblanching purpura develop, and gravity’s effect on the deposition of immune complex material dictates how lesions are distributed.

“Manifestations more typical of medium vessel vasculitis include subcutaneous nodules, livedo reticularis, retiform purpura, larger hemorrhagic bullae, and more significant ulceration and necrosis,” he said. “If such lesions are seen, suspect medium-vessel vasculitis or vasculitis overlapping small and medium vessels.” Cutaneous or systemic polyarteritis nodosa, antineutrophilic cytoplasmic autoantibody (ANCA)–associated vasculitis, and cryoglobulinemic vasculitis are examples, he added.

The particularities of renal manifestations of vasculitis also offer clues to the vessels involved. When a vasculitis patient has glomerulonephritis, suspect small-vessel involvement, Dr. Micheletti said. However, vasculitis affecting medium-sized vessels will cause renovascular hypertension and, potentially renal arterial aneurysms.

Nerves are typically spared in small-vessel vasculitis, while wrist or foot drop can be seen in mononeuritis multiplex.

Recently, the Diagnostic and Classification Criteria in Vasculitis Study (DCVAS) looked at more than 6,800 patients at over 130 sites around the world, proposing new classification criteria for ANCA-associated vasculitis (AAV) and large-vessel vasculitis. The study found that skin findings are common in AAV, with 30%-50% of cases presenting initially with skin lesions. Petechiae and/or purpura are the most common of the skin manifestations, he said. By contrast, for EGPA, allergic and nonspecific findings were the most common findings.

Although skin biopsy can confirm the diagnosis in up to 94% of AAV cases, it’s underutilized and performed in less than half (24%-44%) of cases, Dr. Micheletti said. The study’s findings “demonstrate the importance of a good skin exam, as well as its utility for diagnosis” of vasculitis, he said.

An additional finding form the DCVAS study was that skin lesions can give clues to severity of vasculitis: “Among 1,184 patients with ANCA-associated vasculitis, those with cutaneous involvement were more likely to have systemic manifestations of disease, more likely to have such severe manifestations as glomerulonephritis, alveolar hemorrhage, and mononeuritis,” said Dr. Micheletti, with a hazard ratio of 2.0 among those individuals who had EGPA or GPA.

“Skin findings have diagnostic and, potentially, prognostic importance,” he said. “Use the physician exam and your clinical acumen to your advantage,” but always confirm vasculitis with a biopsy. “Clinicopathologic correlation is key.” A simple urinalysis will screen for renal involvement, and is of “paramount importance,” he added.

Dr. Micheletti reported that he had no relevant disclosures.

WAIKOLOA, HAWAII – The work up of a case of onychomycosis doesn’t end with the detection of fungal hyphae.

Trichophyton rubrum remains the most common cause of toenail fungus in the United States, but nondermatophyte molds – Scopulariopsis, Fusarium, and others – are on the rise, so it’s important to speciate, especially when patients have atypical presentations or fail to respond to the T. rubrum go-to treatment, terbinafine, according to Nathaniel Jellinek, MD, of the department of dermatology, Brown University, Providence, R.I.

Standard in-office potassium hydroxide (KOH) testing can’t distinguish one species of fungus from another, nor can pathology with Gomori methenamine silver (GMS) or Periodic acid-Schiff (PAS) staining. Both culture and polymerase chain reaction (PCR), however, do.

Since few hospitals are equipped to run those tests, Dr. Jellinek uses the Case Western Center for Medical Mycology, in Cleveland, for testing.

In an interview at the Hawaii Dermatology Seminar provided by the Global Academy for Medical Education/Skin Disease Education Foundation, Dr. Jellinek explained how to speciate, and the importance of doing so.

He also shared his tips on getting good nail clippings and good scrapings for debris for testing, and explained when KOH testing is enough – and when to opt for more advanced diagnostic methods, including PCR, which he said trumps all previous methods.

Terbinafine is still the best option for T. rubrum, but new topicals are better for nondermatophyte molds. There’s also a clever new dosing regimen for terbinafine, one that should put patients at ease about liver toxicity and other concerns. “If you tell them they’re getting 1 month off in the middle, it seems to go over a little easier,” Dr. Jellinek said.

Mortality within 90 days of infection was 45% among 51 patients diagnosed with antibiotic-resistant Candida auris infections in a multihospital outbreak in New York City from 2012 to 2017.

Transmission is ongoing in health care facilities, primarily among patients with extensive health care exposures, according to a report published in Emerging Infectious Diseases.

In the intensive case-patient analysis conducted by the New York State Health Department, 21 cases were from seven hospitals in Brooklyn, 16 were from three hospitals and one private medical office in Queens, 12 were from five hospitals and one long-term acute care hospital in Manhattan, and 1 was from a hospital in the Bronx. The remaining clinical case was identified in a western New York hospital in a patient who had recently been admitted to an involved Brooklyn hospital.

Among these patients, 31 (61%) had resided in long-term care facilities immediately before being admitted to the hospital in which their infection was diagnosed, and 19 of these 31 resided in skilled nursing facilities with ventilator beds; 1 (2%) resided in a long-term acute care hospital; 5 (10%) had been transferred from another hospital; and 4 (8%) had traveled internationally within 5 years before diagnosis, according to the investigators.

Isolates from 50 patients (98%) were resistant to fluconazole and 13 (25%) were resistant to fluconazole and amphotericin B. No initial isolates were resistant to echinocandins, although subsequent isolates obtained from 3 persons who had received an echinocandin acquired resistance to it, according to the researchers. Whole-genome sequencing performed at The Centers for Disease Control and Prevention indicated that 50 of 51 isolates belonged to a South Asia clade; the remaining isolate was the only one susceptible to fluconazole.

The work was supported by the CDC. No disclosures were reported.

CHICAGO – Though research shows that nail fungus occurs in just 0.3% of pediatric patients in the United States, that’s not what Sheila Friedlander, MD, is seeing in her southern California practice, where it’s not uncommon to see children whose nails, toe nails in particular, have fungal involvement.

“I know I started out telling you fungus isn’t that common in children … but you do need to think about it,” said Dr. Friedlander during a nail-focused session at the annual summer meeting of the American Academy of Dermatology. Dr. Friedlander, professor of dermatology and pediatrics at the University of California San Diego and Rady Children’s Hospital, said that she suspects that more participation in organized sports at a young age may be contributing to the increase, with occlusive sports footwear replacing bare feet or sandals for more hours of the day, presenting more opportunities for toenail trauma in sports such as soccer.

When making the clinical call about a nail problem, bear in mind that the younger the child, the less likely a nail problem is fungal, Dr. Friedlander noted. “Little children are much less likely than older children to have nail fungus. Pediatric nails are thinner, and they are faster growing, with better blood supply to the matrix.”

And if frank onychomadesis is observed, think about the time of year, and ask about recent fevers and rashes, because coxsackievirus may be the culprit. “Be not afraid, and look everywhere if the nail is confusing to you,” she said. In all ages, the diagnosis is primarily clinical, “but I culture them, I ‘PAS’ [periodic acid-Schiff stain] them, too. If you do both, you’ll increase your yield,” Dr. Friedlander said, adding, “the beauty of PAS is you can use it to give your families an answer very soon.”

Once you’ve established that fungus is to blame for a nail problem, there’s a conundrum: There are no Food and Drug Administration-approved therapies, either topical or systemic, for pediatric onychomycosis, Dr. Friedlander said. She, along with coauthors and first author Aditya Gupta, MD, of Mediprobe Research, London, Ontario, Canada, recently published an article reviewing the safety and efficacy of antifungal agents in this age group (Pediatr Dermatol. 2018 Jun 26. doi: 10.1111/pde.13561).

Reviewing information available in the United States and Canada, Dr. Friedlander and her coauthors came up with three topical and four oral options for children, along with recommendations for dosage and duration.

In response to an audience question about the use of topical antifungal treatment for nail involvement, Dr. Friedlander responded, “I think topicals would be great for kids, but it’s for kids where there is no nail matrix involvement. Also, cost is a problem. Nobody will cover it. But some families are willing to do this to avoid systemic therapy,” and if the family budget can accommodate a topical choice, it’s a logical option, she said, noting that partial reimbursement via a coupon system is available from some pharmaceutical companies.

Where appropriate, ciclopirox 8%, efinaconazole 10%, and tavaborole 5% can each be considered. Dr. Friedlander cited one study she coauthored, which reported that 70% of pediatric participants with nonmatrix onychomycosis saw effective treatment, with a 71% mycological cure rate (P = .03), after 32 weeks of treatment with ciclopirox lacquer versus vehicle (Pediatr Dermatol. 2013 May-Jun;30[3]:316-22).

Systemic therapies – which, when studied, have been given at tinea capitis doses – could include griseofulvin, terbinafine, itraconazole, and fluconazole.

In terms of oral options, Dr. Friedlander said, griseofulvin has some practical limitations. While prolonged treatment is required in any case, terbinafine may produce results in about 3 months, whereas griseofulvin may require up to 9 months of therapy. “I always try to use terbinafine … griseofulvin takes a year and a day,” she said.

She also shared some tips to improve pediatric adherence with oral antifungals: “You can tell parents to crush terbinafine tablets and mix in peanut butter or applesauce to improve adherence. Griseofulvin can be flavored by the pharmacy, but volumes are big with griseofulvin, so it’s a challenge to get kids to take it all,” she said.

Dr. Friedlander reported that she had no relevant financial disclosures.

CHICAGO – Though research shows that nail fungus occurs in just 0.3% of pediatric patients in the United States, that’s not what Sheila Friedlander, MD, is seeing in her southern California practice, where it’s not uncommon to see children whose nails, toe nails in particular, have fungal involvement.

“I know I started out telling you fungus isn’t that common in children … but you do need to think about it,” said Dr. Friedlander during a nail-focused session at the annual summer meeting of the American Academy of Dermatology. Dr. Friedlander, professor of dermatology and pediatrics at the University of California San Diego and Rady Children’s Hospital, said that she suspects that more participation in organized sports at a young age may be contributing to the increase, with occlusive sports footwear replacing bare feet or sandals for more hours of the day, presenting more opportunities for toenail trauma in sports such as soccer.

When making the clinical call about a nail problem, bear in mind that the younger the child, the less likely a nail problem is fungal, Dr. Friedlander noted. “Little children are much less likely than older children to have nail fungus. Pediatric nails are thinner, and they are faster growing, with better blood supply to the matrix.”

And if frank onychomadesis is observed, think about the time of year, and ask about recent fevers and rashes, because coxsackievirus may be the culprit. “Be not afraid, and look everywhere if the nail is confusing to you,” she said. In all ages, the diagnosis is primarily clinical, “but I culture them, I ‘PAS’ [periodic acid-Schiff stain] them, too. If you do both, you’ll increase your yield,” Dr. Friedlander said, adding, “the beauty of PAS is you can use it to give your families an answer very soon.”

Once you’ve established that fungus is to blame for a nail problem, there’s a conundrum: There are no Food and Drug Administration-approved therapies, either topical or systemic, for pediatric onychomycosis, Dr. Friedlander said. She, along with coauthors and first author Aditya Gupta, MD, of Mediprobe Research, London, Ontario, Canada, recently published an article reviewing the safety and efficacy of antifungal agents in this age group (Pediatr Dermatol. 2018 Jun 26. doi: 10.1111/pde.13561).

Reviewing information available in the United States and Canada, Dr. Friedlander and her coauthors came up with three topical and four oral options for children, along with recommendations for dosage and duration.

In response to an audience question about the use of topical antifungal treatment for nail involvement, Dr. Friedlander responded, “I think topicals would be great for kids, but it’s for kids where there is no nail matrix involvement. Also, cost is a problem. Nobody will cover it. But some families are willing to do this to avoid systemic therapy,” and if the family budget can accommodate a topical choice, it’s a logical option, she said, noting that partial reimbursement via a coupon system is available from some pharmaceutical companies.

Where appropriate, ciclopirox 8%, efinaconazole 10%, and tavaborole 5% can each be considered. Dr. Friedlander cited one study she coauthored, which reported that 70% of pediatric participants with nonmatrix onychomycosis saw effective treatment, with a 71% mycological cure rate (P = .03), after 32 weeks of treatment with ciclopirox lacquer versus vehicle (Pediatr Dermatol. 2013 May-Jun;30[3]:316-22).

Systemic therapies – which, when studied, have been given at tinea capitis doses – could include griseofulvin, terbinafine, itraconazole, and fluconazole.

In terms of oral options, Dr. Friedlander said, griseofulvin has some practical limitations. While prolonged treatment is required in any case, terbinafine may produce results in about 3 months, whereas griseofulvin may require up to 9 months of therapy. “I always try to use terbinafine … griseofulvin takes a year and a day,” she said.

She also shared some tips to improve pediatric adherence with oral antifungals: “You can tell parents to crush terbinafine tablets and mix in peanut butter or applesauce to improve adherence. Griseofulvin can be flavored by the pharmacy, but volumes are big with griseofulvin, so it’s a challenge to get kids to take it all,” she said.

The use of nanotechnology significantly reduced the amount of efinaconazole needed to effectively treat nail fungus in a study that pitted nitric oxide–releasing nanoparticles combined with the antifungal against reference strains of Trichophyton rubrum.

Efinaconazole has demonstrated effectiveness as a topical treatment for T. rubrum, but treatment can be expensive, with a single 4-mL bottle costing $691 at a major chain pharmacy, wrote Caroline B. Costa-Orlandi, PhD, of Universidade Estadual Paulista, Sao Paulo, Brazil, and her colleagues.

In a study published in the Journal of Drugs in Dermatology, an international research team evaluated topical efinaconazole and topical terbinafine, each combined with previously characterized, nitric oxide–releasing nanoparticles (NO-np) in a checkerboard design, to attack two reference strains of T. rubrum, ATCC MYA-4438 and ATCC 28189. NO-np was combined with 10% efinaconazole or with terbinafine.

The combination of NO-np and efinaconazole reduced the minimum inhibitory concentration (MIC) of efinaconazole by 16 times compared with treatment alone against ATCC MYA-4438; by 4 times when combined against ATCC 28189. With NO-np plus terbinafine, MICs against ATCC 28189 and ATCC MYA-4438 were reduced by four- and twofold, respectively, when compared with terbinafine alone. These data follow recently published findings in a study cited by the authors that demonstrated that NO-np is superior to topical terbinafine 1% cream in clearing infection in a mouse model of deep dermal dermatophytosis, suggesting that the combination may be even more effective (Nanomedicine. 2017 Oct;13[7]:2267-70).

“What we found was that we could impart the same antifungal activity at the highest concentrations tested of either alone by combining them at a fraction of these concentrations,” corresponding author Adam Friedman, MD, professor of dermatology, George Washington University, Washington, said in a press release issued by the university. The impact of this combination, “which we visualized using electron microscopy as compared to either product alone, highlighted their synergistic damaging effects at concentrations that would be completely safe to human cells,” he added.

Other benefits of NO-np include low cost, safety, ease of use, reduced likelihood for the development of antimicrobial resistance, and proven efficacy against other dermatophyte infections, the researchers noted.

The findings support the potential value of further research to evaluate nanoparticles combined with topical antifungals in a clinical setting, they said.

Dr. Costa-Orlandi had no financial conflicts to disclose. Authors Adam Friedman, MD, and Joel Friedman, MD, are coinventors of the nitric oxide–releasing nanoparticles used in the study. Dr. Adam Friedman is on the advisory board of Dermatology News.

SAN DIEGO – Several device-based therapies are currently being evaluated as treatments for onychomycosis.

These include photodynamic therapy, which has been studied in two clinical trials and case series, Shari Lipner, MD, PhD, said in a video interview at the annual meeting of the American Academy of Dermatology, where she presented on this topic.

“Something that we’re looking at is plasma treatment of onychomycosis basically using ionized gas,” which has been shown to inhibit the growth of Trichophyton rubrum in vitro, added Dr. Lipner of the department of dermatology, Cornell University, New York.

In a pilot study of 19 patients with onychomycosis, she and her associates found that the clinical cure with nonthermal plasma was about 50% and the mycological cure rate was 15%, “and we’re now trying to improve efficacy using this device,” she said (Clin Exp Dermatol. 2017 Apr;42[3]:295-8). With a dielectric insulator, “nonthermal plasma is created by short pulses (about 10 ns) of strong (about 20 kV/mm peak) electric field that ionizes air molecules, creating ions and electrons, as well as ozone, hydroxyl radicals and nitric oxide,” according to the description in the study.

Other device-based therapies include iontophoresis, using electrical currents to increase drug delivery, and creating small punch biopsies or using a device to create “microholes” in the nails to increase delivery of topical medication across the nail, Dr. Lipner said.

Patients often ask about another device-based treatment, laser therapy, which she pointed out is not approved by the Food and Drug Administration for cure, but for a temporary increase in clear nail in patients with onychomycosis, “very different” than the criteria used for topical and systemic medications, making it difficult to compare efficacy data between lasers and medications, she noted.

The tyrosine kinase inhibitor ibrutinib (Imbruvica) may be associated with early-onset invasive fungal infections (IFI) in patients with hematologic malignancies, investigators caution.

French investigators identified 33 cases of invasive fungal infections occurring among patients who had been treated with ibrutinib as monotherapy or in combination with other agents. Of the 33 cases, 27 were invasive aspergillosis, and 40% of these were localized in the central nervous system. The findings were published in the journal Blood.

“IFI tend to occur within the first months of treatment and are infrequent thereafter. Whilst it seems difficult at this point to advocate for systematic antifungal prophylaxis in all patients, an increased awareness about the potential risk of IFI after initiating ibrutinib is warranted, especially when other predisposing factors are associated,” wrote David Ghez, MD, PhD, and colleagues at the Gustave Roussy Institute in Villejuif and other centers in France.

Although ibrutinib, an inhibitor of Bruton’s tyrosine kinase, is generally considered to be less immunosuppressive than other therapies, it was associated with five cases of Pneumocystis jirovecii pneumonia in patients with chronic lymphocytic leukemia (CLL) treated with ibrutinib monotherapy in a 2016 report (Blood. 2016;128:1940-3). Of these five patients, four were treatment naive, suggesting that ibrutinib itself could increase risk for invasive opportunistic infections, Dr. Ghez and his colleagues noted.

KAUAI, HAWAII – When it comes to diagnosing tinea capitis, you really can’t rely on a Wood’s lamp, according to pediatric dermatologist Robert Silverman, MD.

The Wood’s lamp generally misses the most common cause of tinea capitis in urban and suburban environments today, Trichophyton tonsurans, said Dr. Silverman, a pediatric dermatologist and clinical associate professor in the department of pediatrics at Georgetown University, Washington.

The dermatoscope, which “will allow you to see what is called the black dots of tinea capitis very, very closely,” is far better, he said in an interview at the Hawaii Dermatology Seminar provided by the Global Academy for Medical Education/Skin Disease Education Foundation

He explained the limitations of the Wood’s lamp in this setting, and what to look for with a dermatoscope. He had other tips to share, too, from years of experience treating the condition, including how to differentiate tinea capitis on exam from its most common mimics, why it’s best to include a counter stain when using potassium hydroxide, and how to motivate parents to wash their child’s hair more frequently to reduce spores on the hair and scalp.

Dr. Silverman disclosed relationships with Pierre Fabre, Pfizer, and Regeneron.

Fungi and bacteria in the gastrointestinal tract collaboratively form biofilms that may exacerbate inflammation in patients with inflammatory bowel disease (IBD), a review article concluded.

In particular, the investigators found patients with Crohn’s disease (CD) had higher levels of the fungus Candida tropicalis, and of two bacteria, Escherichia coli and Serratia marcescens, compared with healthy family members.

Furthermore, these three organisms “worked together to form robust biofilms capable of exacerbating intestinal inflammation,” wrote authors Christopher L. Hager, MD, and Mahmoud A. Ghannoum, PhD, of the center for medical mycology at Case Western Reserve University, Cleveland, and University Hospitals Cleveland Medical Center.

This “interkingdom interaction” suggests a potential role for antifungals combined with probiotics as a treatment strategy for patients with IBD, they said in their review article discussing both their own studies to date and those by other research groups.

“These studies clearly demonstrate that mycobiome/bacteriome interactions play an important role in the perpetuation of GI inflammation,” they wrote (Dig Liver Dis. 2017 Nov;49[11]:1171-6). “Not only have we shown that fungi are important for overall GI tract health, we have also shown that overgrowth of the fungus due to imbalance has deleterious effects on the gastric mucosa.”

Dr. Ghannoum and his colleagues first highlighted the importance of the mycobiome in a 2010 study that used deep sequencing to characterize the human oral fungal community (PLOS Pathogens. 2010 Jan 8. doi: 10.1371/journal.ppat.1000713). They found that humans were colonized with Candida, as was expected, but also with species including Aspergillus, Cryptococcus, and Fusarium, which was unexpected, Dr. Hager and Dr. Ghannoum wrote in their review.

In their more recent work, Dr. Ghannoum, Dr. Hager, and their coinvestigators compared CD patients with their healthy relatives and found increased levels of E. coli, S. marcescens, and the fungus C. tropicalis in the gastrointestinal tract (mBio. 2016 Sep 20. doi: 10.1128/mBio.01250-16). In vitro, those three organisms cooperate to form biofilms that could activate the host immune response, they said.

“These findings suggest a possible role of these pathogenic organisms in the initiation and perpetuation of chronic intestinal inflammation, such as that observed in patients with inflammatory bowel disease,” they wrote. “Not only has this opened up the possibility of new therapeutic approaches in patients with IBD (i.e., antifungals/antibiotics), it has also paved the way for groundbreaking research on probiotic development aimed at disrupting GI biofilm formation, thus ending a vicious cycle of chronic intestinal inflammation.”

Developing new probiotic therapies that leverage mycobiome-level observations could help overcome some limitations of current treatment options for IBD, such as biologic therapies and antibiotics, the authors wrote.

Biologics can block immune pathways implicated in mucosal inflammation and lead to potentially deleterious secondary infections, they explained. Likewise, antibiotics can be effective in controlling inflammatory symptoms but raise the concern of potentially increasing antibiotic resistance.

Although new probiotic research could provide a new avenue of treatment, development of clinical studies could be limited in part, they said, because probiotics are considered to be food supplements rather than drugs regulated by the Food and Drug Administration.

“Conducting such trials is challenging due to the lack of funding, leaving companies with very little impetus to perform long, expensive, placebo-controlled studies,” the authors wrote.

The authors declared no conflicts of interest.

Furthermore, these three organisms “worked together to form robust biofilms capable of exacerbating intestinal inflammation,” wrote authors Christopher L. Hager, MD, and Mahmoud A. Ghannoum, PhD, of the center for medical mycology at Case Western Reserve University, Cleveland, and University Hospitals Cleveland Medical Center.

This “interkingdom interaction” suggests a potential role for antifungals combined with probiotics as a treatment strategy for patients with IBD, they said in their review article discussing both their own studies to date and those by other research groups.

“These studies clearly demonstrate that mycobiome/bacteriome interactions play an important role in the perpetuation of GI inflammation,” they wrote (Dig Liver Dis. 2017 Nov;49[11]:1171-6). “Not only have we shown that fungi are important for overall GI tract health, we have also shown that overgrowth of the fungus due to imbalance has deleterious effects on the gastric mucosa.”

Dr. Ghannoum and his colleagues first highlighted the importance of the mycobiome in a 2010 study that used deep sequencing to characterize the human oral fungal community (PLOS Pathogens. 2010 Jan 8. doi: 10.1371/journal.ppat.1000713). They found that humans were colonized with Candida, as was expected, but also with species including Aspergillus, Cryptococcus, and Fusarium, which was unexpected, Dr. Hager and Dr. Ghannoum wrote in their review.

In their more recent work, Dr. Ghannoum, Dr. Hager, and their coinvestigators compared CD patients with their healthy relatives and found increased levels of E. coli, S. marcescens, and the fungus C. tropicalis in the gastrointestinal tract (mBio. 2016 Sep 20. doi: 10.1128/mBio.01250-16). In vitro, those three organisms cooperate to form biofilms that could activate the host immune response, they said.

“These findings suggest a possible role of these pathogenic organisms in the initiation and perpetuation of chronic intestinal inflammation, such as that observed in patients with inflammatory bowel disease,” they wrote. “Not only has this opened up the possibility of new therapeutic approaches in patients with IBD (i.e., antifungals/antibiotics), it has also paved the way for groundbreaking research on probiotic development aimed at disrupting GI biofilm formation, thus ending a vicious cycle of chronic intestinal inflammation.”

Developing new probiotic therapies that leverage mycobiome-level observations could help overcome some limitations of current treatment options for IBD, such as biologic therapies and antibiotics, the authors wrote.

Biologics can block immune pathways implicated in mucosal inflammation and lead to potentially deleterious secondary infections, they explained. Likewise, antibiotics can be effective in controlling inflammatory symptoms but raise the concern of potentially increasing antibiotic resistance.

Although new probiotic research could provide a new avenue of treatment, development of clinical studies could be limited in part, they said, because probiotics are considered to be food supplements rather than drugs regulated by the Food and Drug Administration.

“Conducting such trials is challenging due to the lack of funding, leaving companies with very little impetus to perform long, expensive, placebo-controlled studies,” the authors wrote.

The authors declared no conflicts of interest.
