The use of anti-tumour necrosis factor therapy in HIV-positive individuals with rheumatic disease

Management of postinfectious inflammatory arthritis

PURPOSE OF REVIEW

Postinfectious inflammatory arthritis can result from various pathogens, including bacteria, viruses, fungi, and parasites. Prompt identification and treatment of acute infection is vital, but some cases progress to chronic arthritis despite successful treatment of infection. Postinfectious inflammatory arthritis varies from mild, self-limited arthralgia to severe, refractory arthritis, necessitating ongoing disease-modifying treatment. This review explores the spectrum of postinfectious inflammatory arthritis to provide insights into effective management.

RECENT FINDINGS

Research continues regarding the benefit of antimicrobial therapy, beyond treatment of the acute infection, to diminish the severity of postinfectious inflammatory arthritis. Following treatment of acute infection, most cases are self-limited so treatment is symptomatic. However, a difficult-to-predict fraction of cases develop chronic postinfectious inflammatory arthritis that can be challenging to manage. Recently, as more biologic, and targeted synthetic DMARDs have become available, treatment options have expanded.

SUMMARY

In this article, we use the term 'postinfectious inflammatory arthritis' rather than 'reactive arthritis' because it describes a broader spectrum of diseases and emphasizes the common pathogenesis of a postinfectious inflammatory process. We summarize the conventional therapies and recent management developments for the most frequently encountered postinfectious inflammatory arthritides.

HIV: Inflammatory dermatoses

Patients living with HIV may experience a variety of inflammatory dermatoses, ranging from exacerbations of underlying conditions to those triggered by HIV infection itself. This article presents a current literature review on the etiology, diagnosis and management of atopic dermatitis, psoriasis, pityriasis rubra pilaris, lichen planus, seborrheic dermatitis, eosinophilic folliculitis, pruritic papular eruption and pruritus, in patients living with HIV.

The use of a tumor necrosis factor inhibitor-adalimumab-in the management of arthritis in an adolescent with HIV: A case report

Human immunodeficiency virus (HIV) infection is associated with a myriad of musculoskeletal manifestations. Inflammatory arthritis has been described in association with HIV in both adults and children. Biologic disease-modifying anti-rheumatic drugs, particularly tumor necrosis factor inhibitors (TNFi), have been reported to manage inflammatory arthritis in adults with HIV when conventional therapy fails to control arthritis. In this report, we describe the management of arthritis and enthesitis in a 12-year-old adolescent male with HIV using the TNFi adalimumab. At the time of presentation, the patient was on highly active antiretroviral therapy for 1 year. His viral load was <40 copies/mL, and the CD4+ T-cell count was 1280 cells/mm3 . He had a positive antinuclear antibody and HLA-B27. Rheumatoid factor was negative. After screening for hepatitis B and C and latent tuberculosis, the patient was started on adalimumab. This report describes the successful control of recalcitrant arthritis and enthesitis in a pediatric patient with HIV infection using adalimumab.

Biologic Therapies in HIV/AIDS Patients with Inflammatory Diseases: A Systematic Review of the Literature

Biologic therapies have been increasingly developed and used for the treatment of severe inflammatory diseases. However, the safety and efficacy profile of biologic drugs in patients with HIV is not well established as this patient population is historically excluded from clinical trials. We review the available evidence of biologic use in people with HIV. We conducted a systematic review of the literature up to June 29, 2022 and included studies that treated patients with HIV who have inflammatory disease using biologic drugs. Clinical data regarding safety and efficacy were abstracted into tables. One hundred twelve studies were included, and 179 patients were included in our study. Nearly all classes of biologics drugs had a favorable safety profile with minimal or minor adverse events. Anti-CD-20 inhibitors and TNF-alpha inhibitors were associated with opportunistic infections. Transient increase in HIV viral load was noted with use of some agents such as TNF-alpha inhibitors. The quality of evidence is low, restricted to case reports and retrospective reviews. However, the safety profile of biologics observed in these patients with HIV was overall favorable.

Interleukin-17A Inhibitor Secukinumab Treatment in HIV-Positive Psoriasis Patient: A Case Report

Psoriasis is an immune-mediated chronic inflammatory dermatosis influenced by hereditary and environmental factors. Human immunodeficiency virus (HIV) infection affects the immune system and exacerbates psoriatic lesions. We report the case of a 33-year-old male patient diagnosed with psoriasis vulgaris, psoriatic arthritis and HIV infection. Acitretin capsules, etanercept and high-active antiretroviral therapy (HAART) were effective. Two months after etanercept was discontinued, his condition worsened. After switching to secukinumab combined with HAART, the symptoms of psoriatic arthritis resolved rapidly after four weeks, with a Disease Activity Index for Psoriatic Arthritis score of 0. The time to achieve psoriasis area and severity index 40, 75, 90, and 100 were 2, 4, 8, and 29 weeks. The treatment was maintained for 1 year with no adverse reactions. Regarding the stable CD4⁺ T lymphocyte count and the viral load, administering anti-IL-17 monoclonal antibodies is an effective treatment option for psoriasis patients.

Systematic literature review informing the 2022 EULAR recommendations for screening and prophylaxis of chronic and opportunistic infections in adults with autoimmune inflammatory rheumatic diseases

OBJECTIVE

To conduct a systematic literature review (SLR) on the screening and prophylaxis of opportunistic and chronic infections in autoimmune inflammatory rheumatic diseases (AIIRD).

METHODS

SLR (inception-12/2021) based on the following search domains: (1) infectious agents, (2) AIIRD, (3) immunosuppressives/immunomodulators used in rheumatology, (4) screening terms and (5) prophylaxis terms. Articles were retrieved having the terms from (1) AND (2) AND (3) plus terms from (4) OR(5). Databases searched: PubMed, Embase and Cochrane Library.

EXCLUSION CRITERIA

studies on postoperative infections, paediatric AIIRD, COVID-19, vaccinations and non-Εnglish literature. Study quality was assessed with Newcastle-Ottawa scale for non-randomised controlled trials (RCTs), RoB-Cochrane for RCTs, AMSTAR2 for SLRs.

RESULTS

From 5641 studies were retrieved, 568 full-text articles were assessed for eligibility, with 194 articles finally included. For tuberculosis, tuberculin skin test (TST) is affected by treatment with glucocorticoids and conventional synthetic disease modifying anti-rheumatic drugs (DMARDs) and its performance is inferior to interferon gamma release assay (IGRA). Agreement between TST and IGRA is moderate to low. For hepatitis B virus (HBV): risk of reactivation is increased in patients positive for hepatitis B surface antigen. Anti-HBcore positive patients are at low risk for reactivation but should be monitored periodically with liver function tests and/or HBV-viral load. Risk for Hepatitis C reactivation is existing but low in patients treated with biological DMARDs. For Pneumocystis jirovecii, prophylaxis treatment should be considered in patients treated with prednisolone ≥15-30 mg/day for >2-4 weeks.

CONCLUSIONS

Different screening and prophylaxis approaches are described in the literature, partly determined by individual patient and disease characteristics.

Impact and Tolerance of Immunosuppressive Treatments in Patients Living with HIV with Inflammatory or Autoimmune Diseases

Background: Patients living with HIV (PLWHIV) can develop autoimmune diseases (AD) needing immunosuppressive treatments (IST). This study aims to describe the impact of IST in PLWHIV. Methods: This was a multicentric retrospective observational study in six HIV referral centers on PLWHIV under IST for AD. Demographic factors, viral co-infections, immunovirological status before and under IST, infectious events, and their descriptions were collected and described focusing on infectious events, immunovirological variations, and IST effectiveness. Results: 9480 PLWHIV were screened for inclusion. Among them, 138 (1.5%) had a history of auto-immune disease, among which 32 (23%) received IST. There was mainly spondyloarthropathy (28%) and the most commonly used IST was methotrexate. The median follow-up under IST was 3.8 years (2.7; 5.9). There were 15 infectious events (0.5 events/individuals) concerning nine patients. At the last medical follow-up, 81% of these were in remission of their AD. Under IST, there was an increase in CD4 during follow-up (629 vs. 827 CD4/mm³, p = 0.04). No HIV virological failure was noted. Conclusions: This study supports a growing evidence base that IST can be used safely and effectively in PLWHIV with careful monitoring.

Case report: Safety and efficacy of adalimumab in treating difficult-to-treat rheumatoid arthritis in a human immunodeficiency virus-positive patient, one year follow-up

Rheumatoid arthritis (RA) is a joint-disabling inflammatory disease associated with the pathology of synovitis. Some patients with RA are difficult to treat, using disease-modifying anti-rheumatic drugs (DMARDs). Biology and targeted synthetic DMARDs (b/tsDMARDs) are options for patients with RA. Acquired immunodeficiency syndrome (AIDS) is an infectious disease caused by the human immunodeficiency virus (HIV). Adalimumab is an anti-tumor necrosis factor therapy commonly used in patients with RA. However, there are no reports or related data on patients with RA-HIV/AIDS treated with adalimumab are available. In this report, we described the first successful case of a 60-year-old HIV-positive woman with difficult-to-treat RA treated with ADA after being screened for hepatitis virus, latent tuberculosis (LTBI), and other infections. She contracted HIV from sexual exposure while on adalimumab therapy. As the patient was resistant to first-line DMARDs, she continued adalimumab along with the initiation of highly active antiretroviral therapy (HAART). The patient was treated with adalimumab therapy for a year; her CD4+ lymphocyte count was normal, HIV-1 RNA decreased, and no new infections were triggered. The patient achieved clinical remission of RA. In conclusion, adalimumab is a safe option for patients with RA-HIV and may slow the progression of HIV infection. Furthermore, HAART has the potential to reduce joint pain and fatigue in patients with difficult-to-treat RA.

Biological treatment usage in patients with HIV and rheumatic disease, 2003-2021: long-term safety and follow-up

Objective

This study examined the safety and efficacy of biological agents, especially tumour necrosis factor (TNF) inhibitors, for HIV-positive rheumatology patients refractory to standard therapy.

Methods

This study is a retrospective case series including patients derived from a community HIV clinic as well as from two academic centres. Initial visit data collected included: sociodemographic characteristics, CD4 counts, HIV viral load and medication use. Patients with persistent disease activity despite standard conservative therapy were begun on biological agents. The main outcomes were patient and physician global assessment of treatment response and medication side effects in patients with rheumatological disorders treated with biological medications over time.

Results

Seventeen patients were seen from 2003 to 2021, including eight from our previous cohort published in 2008 and nine seen since then, five of whom taking TNF blockers for more than 10 years. Three (17.7%) had rheumatoid arthritis, five (29.4%) psoriatic arthritis, four (23.5%) axial spondyloarthritis and the rest (29.4%) peripheral spondyloarthritis. Antiretroviral therapy had been used in 15. All but one had at least a partial response to biological therapy. There were no major infectious episodes necessitating the discontinuation of medications with only one patient discontinuing treatment due to rising HIV viral load. Patients not on antiretroviral therapy reported no adverse side effects from biological therapy. Four patients were switched to ustekinumab, secukinumab, tocilizumab or upadacitinib from anti-TNF therapy without complications.

Conclusions

These data suggest that biological therapy, especially anti-TNF agents are safe and well tolerated in HIV positive individuals even over several years.

Reactivation rates of hepatitis B or C or HIV in patients with psoriasis using biological therapies: a systematic review and meta-analysis

Some biological therapies for psoriasis can cause the reactivation of viral infections. Although recent studies suggest no increased rate of reactivation with biological therapies, some life-threatening cases have been reported. Therefore, this meta-analysis examined the rate of virus reactivation in patients with psoriasis with biological therapies and concurrent hepatitis B virus (HBV), hepatitis C virus (HCV), or human immunodeficiency virus (HIV) infection. PubMed, Embase, and the Cochrane Library were searched for available papers from inception to December 2021. The outcome was the number of patients with virus reactivation after using biological therapies. The random-effect model was used in all analyses. Fourteen reports (1033 patients) were included. The pooled overall rate of virus reactivation was 0.04 (95%CI 0.01-0.09; I² = 67.7%, P < 0.001). The pooled rates of HBV, HCV, and HIV reactivation were 0.04 (95%CI 0.00-0.10; I² = 79.9%, P < 0.001), 0.07 (95%CI 0.02-0.14; I² = 23.7%, P = 0.24), and 0.12 (95%CI 0.00-0.40), respectively. The pooled rates of HBV and HCV reactivation were 0.10 (95%CI 0.03-0.19) and 0.08 (95%CI 0.03-0.15) in Asia, but 0.00 (95%CI 0.00-0.01) and 0.04 (95%CI 0.00-0.21) in Europe. The publication type also influenced the results. The use of biological therapy in patients with psoriasis and HBV, HCV, or HIV infection might be associated with the rate of viral reactivation, but this meta-analysis had limitations, and the evidence might be weak. Nevertheless, it might suggest that at least a consultation with an infection specialist might be warranted in patients with psoriasis in whom biological therapies are considered.

TNF-alpha inhibitors and ustekinumab for the treatment of psoriasis: therapeutic utility in the era of IL-17 and IL-23 inhibitors

Psoriasis is a chronic inflammatory condition for which eleven FDA-approved biologic therapies are approved. Over the past decade, studies have documented the higher efficacy of IL-17 and IL-23 inhibitors for the treatment of psoriasis compared to the TNF-alpha inhibitors and ustekinumab, an IL-12/23 inhibitor. Despite this, there remains an important role for the use of TNF-alpha inhibitors and ustekinumab in the treatment of psoriasis. Here, we review how considerations of infection and malignancy risk, patient demographics, treatment resistance, and co-morbidities may make certain TNF-alpha inhibitors or ustekinumab an excellent choice for therapy in particular patient subgroups.

Novel Therapeutic Approaches to Psoriasis and Risk of Infectious Disease

Psoriasis is a chronic immune-mediated skin and joint disease, with a plethora of comorbidities, characterized by a certain genetic predisposition, and a complex pathogenesis based on the IL-23/IL-17 pathway. There is no doubt that the patients affected by psoriasis are more susceptible to infections as well as that the risk of infection is higher in psoriatic subjects than in the general population. The advent of biotechnological agents on the therapeutic arsenal actually available for the treatment of moderate-to-severe patients, given the fact that the severity of the disease is a predictor of the level of infectious risk, has raised the question of whether these ‘new’ drugs could be considered a safer option and how they can be used in selected cases. Old and newer strategies in cases of chronic infectious conditions are reviewed under the light of clinical trials and other studies present in literature.

Rheumatoid arthritis and HIV-associated arthritis: Two sides of the same coin or different coins

The relationship between rheumatoid arthritis (RA) and human immunodeficiency virus (HIV)-associated arthritis is a complex one that was first described more than three decades ago. There are many similarities and some differences in the clinical presentations of both diseases. In addition, treatment options and long-term monitoring can be challenging in the presence of both disorders, as HIV causes an immunocompromised state and medications used to treat RA are immunosuppressive. In this chapter, we discuss the clinical presentation and the use of conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) and biologic disease-modifying antirheumatic drugs (bDMARDs) in the management of these conditions.

TNF-α inhibition in the setting of undiagnosed HIV infection: a call for enhanced screening guidelines

BACKGROUND

Despite the risks of immunosuppression, recommendations regarding screening for HIV infection prior to initiation of biologic therapies targeting common rheumatologic disorders, including inflammatory bowel disease (IBD) and inflammatory arthritides, are limited. Few cases of patients started on biologics while living with undiagnosed HIV infection have been reported.

METHODS

We report three cases of patients initiated on biologics in the absence of recent or concurrent HIV screening who developed refractory disease or unanticipated complications and were later found to have undiagnosed chronic HIV infection.

RESULTS

In Case 1, a 53-year-old MSM with negative HIV testing 2 years prior presented with presumed rheumatoid arthritis. He did not respond to methotrexate, so adalimumab was started. HIV testing to evaluate persistent symptoms was positive 9 months later; CD4+ T-cell count was 800 cells/μl. Antiretroviral therapy (ART) resulted in resolution of symptoms, which were attributed to HIV-associated arthropathy. In Case 2, a 55-year-old woman with injection drug use in remission and no prior HIV testing presented with hidradenitis suppurativa. She started infliximab and methotrexate therapy with good response. After she developed weight loss and lymphopenia, an HIV test was positive; CD4+ T-cell count was 334 cells/μl. Biologic hidradenitis suppurativa therapy was discontinued, with subsequent poor hidradenitis suppurativa control. In Case 3, a 32-year-old MSM with no prior HIV testing presented with presumed IBD; infliximab and steroids were started. Symptoms progressed despite IBD-directed therapy, and he was diagnosed with extensive Kaposi sarcoma with visceral and cutaneous involvement, likely exacerbated by immunosuppression. HIV testing was positive; CD4+ T-cell count was 250 cells/μl. Kaposi sarcoma initially worsened due to ART-associated immune reconstitution inflammatory syndrome. He is now improving with systemic chemotherapy and ART. HIV-associated Kaposi sarcoma is presumed to be the underlying diagnosis.

CONCLUSION

All three patients had elevated risk for HIV infection, and two had final diagnoses attributed to chronic HIV infection, not warranting therapeutic immunosuppression. Screening for HIV infection prior to initiation of biologic therapy should be incorporated into clinical practice guidelines.

The use of secukinumab in an HIV-positive patient with axial spondyloarthritis: a case-based review

Axial spondyloarthritis in HIV-positive patients raises specific treatment challenges as immunosuppressant and immunomodulating agents may adversely affect the course of the HIV infection and could increase the risk of opportunistic infections. The efficacy and safety of secukinumab in patients with HIV is unknown due to HIV patients were largely excluded from clinical trials and nowadays, the clinical evidence for the treatment with biological disease-modifying antirheumatic drugs (DMARDs) is provided from scarce case reports and case series. We hereby discuss a case of a male patient with concomitant axial spondyloarthritis and HIV infection successfully treated with secukinumab, achieving disease remission and without any associated complications. Nevertheless, the potential long-term effects in the use of monoclonal antibodies with a special emphasis on opportunistic infections, malignancies, and loss of HIV control clearly need to be determined more thoroughly, and continued research efforts are necessary before a clear recommendation can be made.

Society for Immunotherapy of Cancer (SITC) clinical practice guideline on immune checkpoint inhibitor-related adverse events

Immune checkpoint inhibitors (ICIs) are the standard of care for the treatment of several cancers. While these immunotherapies have improved patient outcomes in many clinical settings, they bring accompanying risks of toxicity, specifically immune-related adverse events (irAEs). There is a need for clear, effective guidelines for the management of irAEs during ICI treatment, motivating the Society for Immunotherapy of Cancer (SITC) to convene an expert panel to develop a clinical practice guideline. The panel discussed the recognition and management of single and combination ICI irAEs and ultimately developed evidence- and consensus-based recommendations to assist medical professionals in clinical decision-making and to improve outcomes for patients.

Incident Rheumatoid Arthritis in Human Immunodeficiency Virus Infection: Epidemiology and Treatment

OBJECTIVE

To assess the incidence, presentation, and management of RA in persons with HIV (PWH), including use of disease-modifying anti-rheumatic drugs (DMARDs) in this immunosuppressed population.

METHODS

Patients were included from the Veterans Aging Cohort Study, a longitudinal cohort of Veterans with HIV and matched uninfected Veterans. We identified patients with ≥1 rheumatologist-generated International Classification of Diseases (ICD) code for RA and a measurement of rheumatoid factor (RF) or anti-CCP antibodies. Charts were reviewed using the 2010 RA Classification Criteria to identify incident RA. We recorded use and adverse effects of DMARDs during the first contiguous (no interruption greater than 6 months) course.

RESULTS

We included 56,250 PWH and 116,944 uninfected persons over 2,384,541 person-years. Of 2,748 patients with an RA ICD code, incident RA was identified in 215 patients, including 21 PWH. The incidence rate ratio of RA in PWH vs. uninfected was 0.29 (95% CI 0.19-0.48). Most patients (88%) with RA were seropositive. However, high autoantibody titers were less common in PWH: 5% (1/21) of PWH had both high titer anti-CCP and RF, compared to 41% (82/194) of uninfected. DMARDs were prescribed for 71% (15/21) of PWH with RA, compared to 94% (183/194) of uninfected. Among 10 PWH prescribed DMARDs, we found no signal for worse infectious safety profile compared to 158 HIV-negative controls.

CONCLUSION

Incident RA was less common in PWH than in matched controls. PWH with incident RA had less positive autoantibody profiles than controls and were prescribed DMARDs less frequently.

Biologic Treatment of 4 HIV-Positive Patients: A Case Series and Literature Review

The management of psoriatic disease in human immunodeficiency virus (HIV)-positive patients is challenging. Psoriasis in HIV-positive patients is often severe, progressive, and resistant to first- and second-line therapies, including topical treatments, phototherapy, highly active antiretroviral therapy (HAART), and oral retinoids. Other systemic agents used to treat psoriasis, such as methotrexate and cyclosporine, are immunosuppressants and thus many dermatologists may not feel comfortable prescribing them to HIV-positive patients who are already immunocompromised. Biologic agents, which target specific aspects of overactive immune pathways in psoriasis, have revolutionized the management of moderate-to-severe psoriasis. However, data is limited regarding their safety and efficacy in HIV-positive patients.

OBJECTIVE

Report four cases of HIV-positive patients managed on biologic therapy and summarize the cases of psoriasis in HIV-positive patients managed on biologic therapy that have been published in dermatologic literature to date.

METHODS

We searched PubMed and Embase databases using the terms HIV and psoriasis or HIV and psoriatic arthritis combined with one of the eleven biologics currently approved for treating psoriasis.

RESULTS

We identified 48 cases of anti-psoriasis biologic therapy (including adalimumab, infliximab, etanercept, ustekinumab, and guselkumab) in HIV-positive patients and added four. While data is limited, the evidence available suggests biologic agents are safe and efficacious in moderate-to-severe psoriasis and may even have a favorable effect on CD4 and HIV viral counts when used with concomitant HAART.

CONCLUSION

Further research would be helpful to establish practical guidelines for the use of anti-psoriasis biologic therapy in the HIV population, including that of newer agents.

Infectious Complications of Biological and Small Molecule Targeted Immunomodulatory Therapies

The past 2 decades have seen a revolution in our approach to therapeutic immunosuppression. We have moved from relying on broadly active traditional medications, such as prednisolone or methotrexate, toward more specific agents that often target a single receptor, cytokine, or cell type, using monoclonal antibodies, fusion proteins, or targeted small molecules. This change has transformed the treatment of many conditions, including rheumatoid arthritis, cancers, asthma, and inflammatory bowel disease, but along with the benefits have come risks. Contrary to the hope that these more specific agents would have minimal and predictable infectious sequelae, infectious complications have emerged as a major stumbling block for many of these agents. Furthermore, the growing number and complexity of available biologic agents makes it difficult for clinicians to maintain current knowledge, and most review articles focus on a particular target disease or class of agent. In this article, we review the current state of knowledge about infectious complications of biologic and small molecule immunomodulatory agents, aiming to create a single resource relevant to a broad range of clinicians and researchers. For each of 19 classes of agent, we discuss the mechanism of action, the risk and types of infectious complications, and recommendations for prevention of infection.

Practical Guidelines for Managing Patients With Psoriasis on Biologics: An Update

The paradigm for treating inflammatory diseases has shifted dramatically in the past 10 to 20 years with the discovery of targeted therapeutics or "biologic" agents. Patients with rheumatoid arthritis, inflammatory bowel disease, psoriatic arthritis, and psoriasis, among others, are reaping the benefits of decades of bench to bedside research, allowing them to live more productive lives with less side effects than traditional systemic therapies. Despite these advances, many physicians unfamiliar with biologics are left to care for the basic needs of these patients and may be unaware of the multisystem comorbidities associated with psoriasis and the screening, monitoring, and other special considerations required of biologics patients. This can be overwhelming to primary care physicians and inadvertently expose patients to undue risks. The aim of this review is to provide a practical approach for all health care providers caring for patients with psoriasis being treated with biologics to facilitate communication with their treating dermatologist and ultimately provide patients with more comprehensive care.

Successful treatment of severe perianal Crohn's disease with infliximab in an HIV-positive patient

We present the case of a woman infected with the HIV type 1, controlled with highly active antiretroviral therapy. In the meantime, she developed a severe perianal disease, with complex fistulae and chronic anal fissures. After developing a severe chronic diarrhea, a total ileocolonoscopy with biopsies was performed, showing multiple ileal and segmental colonic erosions. Histology favoured a Crohn's disease diagnosis. Despite the limited experience of anti-tumour necrosis factor agents in the HIV-infected population, infliximab was started in this patient, due to her severe and symptomatic Crohn's disease, with a controlled HIV infection. No side effects were reported and her bowel movements and perianal disease improved right after induction regimen with infliximab. 1 year after starting this therapy she is in clinical and endoscopic remission. The CD4+ T-cell count remained stable, the HIV-RNA undetectable and no opportunistic infections were reported during follow-up period. Data concerning the use of anti-tumour necrosis factor drugs is limited in patients with both inflammatory bowel disease and HIV infection. Only three cases of Crohn's disease and concomitant HIV infection treated with infliximab were reported in the literature. This case report might help future decisions in patients with a similar clinical situation.

[Psoriasis and HIV infection, what do French dermatologists do?]

BACKGROUND

The prevalence of psoriasis among patients presenting human immunodeficiency virus (HIV)infection is the same as in the general population, but the disease is more severe and refractory, and management is more complex. The aim of this survey was to assess the practices of French dermatologists concerning both screening for HIV in psoriasis patients and therapeutic management and follow-up of psoriasis patients with HIV.

PATIENTS AND METHODS

An anonymous national survey of practices was conducted by means of a questionnaire emailed to dermatologists in hospital in private practice in France between March and June 2017.

RESULTS

The questionnaire was completed by 262 dermatologists. They indicated that they carried out screening for HIV in psoriasis patients presenting risk factors (79.4%), prior to biotherapy (63.4%) or different systemic treatments other than retinoids (53.1%), if the psoriasis was severe (45.8%), or in the event of worsening (37.8%). 28.7% of practitioners surveyed were in fact treating patients with psoriasis and HIV, with a mean 3.1 patients being followed up. All practitioners prescribe systemic treatment, other than cyclosporine, but they frequently consult an infectious disease specialist before prescribing these therapies. The most widely used biotherapy was etanercept (65.5% of practitioners). More intensive laboratory follow-up was conducted for these patients in 72.1% of cases.

CONCLUSION

French dermatologists do not perform routine screening for HIV in psoriasis patients. However, where infection has been identified, their practices are modified accordingly. Therapeutic choices are consistent with the French recommendations. Nevertheless, recommendations appear necessary concerning HIV screening in this population.

Review article: managing the adverse events caused by anti-TNF therapy in inflammatory bowel disease

BACKGROUND

Biological therapy is currently widely used to treat IBD. Infliximab, adalimumab and golimumab are currently licensed anti-TNF therapies. Biosimilar anti-TNF monoclonal antibodies are increasingly used. Anti-TNF therapies are widely used and their adverse effects are well characterised, and may cause significant morbidity and mortality in a small proportion of exposed patients. Gastroenterologists need to understand the mechanisms for these effects, recognise these swiftly and manage such events appropriately.

AIM

To cover the range of potential adverse reactions as a result of biologic therapy and specifically management of these events.

METHODS

A Medline and Pubmed search was undertaken. Search terms included were "anti-TNF," "infliximab" or "adalimumab" or "golimumab" combined with the keywords "ulcerative colitis" or "Crohn's disease" or "inflammatory bowel disease" and then narrowed to articles containing the keywords "complications," "side effects" or "adverse events" or "safety profile." International guidelines were also reviewed where relevant.

RESULTS

Adverse events discussed in this review include infusion reactions, blood disorders and infections (including bacterial, viral, fungal and opportunistic infections) as well as autoimmune, dermatological disorders, cardiac and neurological conditions. Malignancies including solid organ, haematological and those linked to viral disease are discussed.

CONCLUSIONS

Anti-TNF therapy has wide-ranging effects on the immune system resulting in a spectrum of potential adverse events in a small proportion of patients. Research advances are improving the understanding, recognition and management of these adverse events.

2018 update of the APLAR recommendations for treatment of rheumatoid arthritis

AIM

To update recommendations based on current best evidence concerning the treatment of rheumatoid arthritis (RA), focusing particularly on the role of targeted therapies, to inform clinicians on new developments that will impact their current practice.

MATERIALS AND METHODS

A search of relevant literature from 2014 to 2016 concerning targeted therapies in RA was conducted. The RA Update Working Group evaluated the evidence and proposed updated recommendations using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach, to describe the quality of evidence and strength of recommendations. Recommendations were finalized through consensus using the Delphi technique.

RESULTS

This update provides 16 RA treatment recommendations based on current best evidence and expert clinical opinion. Recommendations 1-3 deal with the use of conventional synthetic disease-modifying antirheumatic drugs. The next three recommendations (4-6) cover the need for screening and management of infections and comorbid conditions prior to starting targeted therapy, while the following seven recommendations focus on use of these agents. We address choice of targeted therapy, switch, tapering and discontinuation. The last three recommendations elaborate on targeted therapy for RA in special situations such as pregnancy, cancer, and major surgery.

CONCLUSION

Rheumatoid arthritis remains a significant health problem in the Asia-Pacific region. Patients with RA can benefit from the availability of effective targeted therapies, and these updated recommendations provide clinicians with guidance on their use.

HIV-associated psoriasis: Epidemiology, pathogenesis, and management

People living with HIV (PLWH) are affected by a higher incidence skin disorders, which are often associated with high morbidity and mortality. In particular, psoriasis affects PLWH severely and for a longer time than the general population. Human immunodeficiency virus (HIV) infection is characterized by a progressive decrease in CD4⁺ T-cell count, and it could seem paradoxical that psoriasis exacerbations are more frequent in this subset of patients than the general population, even though it is commonly observed at any stage of infection. For a long time, there have been limited therapeutic choices for PLWH affected by psoriasis. The introduction of the combined antiretroviral therapy dramatically changed the natural course of both HIV and psoriasis in PLWH, leading to an improvement of quality and duration of life. However, the clinical severity of psoriasis in PLWH often requires the use of immunosuppressant drugs. Knowledge about their safety and efficacy are limited to case-reports, small case-series and studies, therefore their use has not yet entered the routine. Further studies are needed to determine if immunosuppressive drugs can be safely and effectively used in PLWH affected by psoriasis and other autoimmune disorders.

Safety and effectiveness of conventional systemic therapy and biological drugs in patients with moderate to severe psoriasis and HIV infection: a retrospective multicenter study

Background: The management of HIV-positive patients with psoriasis is controversial and limited to individual cases or short series of patients. Objectives: To evaluate the safety and effectiveness of conventional and biologic immunosuppressive drugs in the treatment of patients with psoriasis and concomitant HIV infection. Methods: A retrospective multicenter study was conducted. The study included data from 2008 to 2016. Inclusion criteria were: HIV adult patients with moderate-to-severe psoriasis, HIV viral load determinations at baseline and at least after 6 months of treatment, and systemic immunosuppressive treatment for at least 6 months. A descriptive analysis was performed. Results: Twenty-three patients with plaque-type psoriasis and HIV infection (five with AIDS) were included. Median follow-up time was 3.2 years. The main drugs used were etanercept, methotrexate, and ustekinumab. In most cases, viral load and CD4 cell count not only remained stable but also improved throughout the follow-up. Six patients presented severe adverse events during the follow-up, four of them in the AIDS stage. At the end of the follow-up period, 76.5% of the patients had achieved a PASI 75. Conclusion: Biologic drugs, both anti-TNF alpha agents and ustekinumab, seem to have an acceptable safety profile and high effectiveness in HIV-positive patients.

Phosphorylated CCAAT/Enhancer Binding Protein β Contributes to Rat HIV-Related Neuropathic Pain: In Vitro and In Vivo Studies

Chronic pain is increasingly recognized as an important comorbidity of HIV-infected patients, however, the exact molecular mechanisms of HIV-related pain are still elusive. CCAAT/enhancer binding proteins (C/EBPs) are expressed in various tissues, including the CNS. C/EBPβ, one of the C/EBPs, is involved in the progression of HIV/AIDS, but the exact role of C/EBPβ and its upstream factors are not clear in HIV pain state. Here, we used a neuropathic pain model of perineural HIV envelope glycoprotein gp120 application onto the rat sciatic nerve to test the role of phosphorylated C/EBPβ (pC/EBPβ) and its upstream pathway in the spinal cord dorsal horn (SCDH). HIV gp120 induced overexpression of pC/EBPβ in the ipsilateral SCDH compared with contralateral SCDH. Inhibition of C/EBPβ using siRNA against C/EBPβ reduced mechanical allodynia. HIV gp120 also increased TNFα, TNFRI, mitochondrial superoxide (mtO₂^·-), and pCREB in the ipsilateral SCDH. ChIP-qPCR assay showed that pCREB enrichment on the C/EBPβ gene promoter regions in rats with gp120 was higher than that in sham rats. Intrathecal TNF soluble receptor I (functionally blocking TNFα bioactivity) or knockdown of TNFRI using antisense oligodeoxynucleotide against TNFRI reduced mechanical allodynia, and decreased mtO₂^·-, pCREB and pC/EBPβ. Intrathecal Mito-tempol (a mitochondria-targeted O₂^·-scavenger) reduced mechanical allodynia and decreased pCREB and pC/EBPβ. Knockdown of CREB with antisense oligodeoxynucleotide against CREB reduced mechanical allodynia and lowered pC/EBPβ. These results suggested that the pathway of TNFα/TNFRI-mtO₂^·--pCREB triggers pC/EBPβ in the HIV gp120-induced neuropathic pain state. Furthermore, we confirmed the pathway using both cultured neurons treated with recombinant TNFα in vitro and repeated intrathecal injection of recombinant TNFα in naive rats. This finding provides new insights in the understanding of the HIV neuropathic pain mechanisms and treatment.SIGNIFICANCE STATEMENT Painful HIV-associated sensory neuropathy is a neurological complication of HIV infection. Phosphorylated C/EBPβ (pC/EBPβ) influences AIDS progression, but it is still not clear about the exact role of pC/EBPβ and the detailed upstream factors of pC/EBPβ in HIV-related pain. In a neuropathic pain model of perineural HIV gp120 application onto the sciatic nerve, we found that pC/EBPβ was triggered by TNFα/TNFRI-mtO₂^·--pCREB signaling pathway. The pathway was confirmed by using cultured neurons treated with recombinant TNFα in vitro, and by repeated intrathecal injection of recombinant TNFα in naive rats. The present results revealed the functional significance of TNFα/TNFRI-mtO₂^·--pCREB-pC/EBPβ signaling in HIV neuropathic pain, and should help in the development of more specific treatments for neuropathic pain.

Assessment and management of musculoskeletal disorders among patients living with HIV

HIV is a global pandemic. However, anti-retroviral therapy has transformed the prognosis and, providing compliance is good, a normal life expectancy can be anticipated. This has led to increasing numbers of people with chronic prevalent, treated infection living to older ages. Musculoskeletal pain is commonly reported by HIV patients and, with resumption of near-normal immune function, HIV-infected patients develop inflammatory rheumatic diseases that require assessment and management in rheumatology clinics. Moreover, it is becoming apparent that avascular necrosis and osteoporosis are common comorbidities of HIV. This review will contextualize the prevalence of musculoskeletal symptoms in HIV, informed by data from a UK-based clinic, and will discuss the management of active inflammatory rheumatic diseases among HIV-infected patients taking anti-retroviral therapy, highlighting known drug interactions.

Rates of Serious Infections in HIV-Infected Patients Receiving Tumor Necrosis Factor Inhibitor Therapy for Concomitant Autoimmune Diseases

OBJECTIVE

To estimate the incidence of serious infections in patients with HIV infection and autoimmune disease who were treated with tumor necrosis factor (TNF) inhibitors, and to compare these rates by stratified viral load levels.

METHODS

Using a unified search strategy, 4 centers identified HIV-infected patients exposed to TNF inhibitors. Patient characteristics and infection data were assessed via chart review in all patients who were ≥18 years old and who received TNF inhibitor therapy after HIV diagnosis, between January 1999 and March 2015.

RESULTS

We studied 23 patients with 26 uses of TNF inhibitor therapy (86.7 person-years of followup). Two (8.7%) experienced at least 1 serious infection episode, for an overall incidence rate of 2.55 per 100 patient-years (95% confidence interval [95% CI] 0.28-9.23). The incidence rate per 100 patient-years was 3.28 (95% CI 0.04-18.26) among patients with a viral load >500 copies/ml at therapy initiation and 2.09 (0.03-11.65) among patients with a viral load ≤500 copies/ml.

CONCLUSION

This study suggests that the rate of serious infections in patients with HIV infection under active care who have received treatment with TNF inhibitors may be comparable to the rates observed in registry databases.

Use of etanercept to treat rheumatoid arthritis in an HIV-positive patient: a case-based review

Rheumatoid arthritis (RA) is a relatively common autoimmune disease that is associated with progressive disability and systemic complications, with a relatively high socioeconomic burden. The treatment of RA has been revolutionized by the use of biological drugs, such as anti-tumor necrosis factor (TNF) agents. A wide spectrum of RA disease severity has been reported among patients with human immunodeficiency virus (HIV) infection. Yet, only a few cases using anti-TNF therapy have been described in this clinical population. Therefore, the aim of our case-based review was to describe the successful use of etanercept in a 38-year-old female patient with RA concomitant with HIV infection, who had been resistant to the first-line anti-rheumatic therapies. As per routine care guidelines, the patient was screened for hepatitis virus infection, latent tuberculosis, and other infectious conditions, prior to the initiation of etanercept treatment. CD4 cell count, HIV viral load, and adverse effects were closely monitored during the treatment. The HIV infection remained stable with etanercept treatment, without the need for anti-retrovirus agents. No adverse effects and serious infections were identified during the treatment. Therefore, anti-TNF therapy is a viable alternative for the treatment of RA in patients with HIV, who do not respond to conventional anti-rheumatic therapies. The relationship between TNF-α and HIV infection, as well as cautionary guidelines regarding the utilization of anti-TNF therapy in this clinical population, is discussed.

Targeting TNF and TNF Receptor Pathway in HIV-1 Infection: from Immune Activation to Viral Reservoirs

Several cellular functions such as apoptosis, cellular proliferation, inflammation, and immune regulation involve the tumor necrosis factor-α (TNF)/TNF receptor (TNFR) pathway. Human immunodeficiency virus 1 (HIV-1) interacts with the TNF/TNFR pathway. The activation of the TNF/TNFR pathway impacts HIV-1 replication, and the TNF/TNFR pathway is the target of HIV-1 proteins. A hallmark of HIV-1 infection is immune activation and inflammation with increased levels of TNF in the plasma and the tissues. Therefore, the control of the TNF/TNFR pathway by new therapeutic approaches could participate in the control of immune activation and impact both viral replication and viral persistence. In this review, we will describe the intricate interplay between HIV-1 proteins and TNF/TNFR signaling and how TNF/TNFR activation modulates HIV-1 replication and discuss new therapeutic approaches, especially anti-TNF therapy, that could control this pathway and ultimately favor the clearance of infected cells to cure HIV-infected patients.

Special situations in inflammatory bowel disease: First Latin American consensus of the Pan American Crohn's and Colitis Organisation (PANCCO) (Second part)

This is the first Latin American Consensus of the Pan American Crohn's and Colitis Organisation (PANCCO) regarding special situations in patients with inflammatory bowel disease (IBD). The aim of this consensus is to raise awareness in the medical community in all Latin American countries with respect to pregnancy, vaccinations, infections, neoplasms, including colorectal cancer, and pediatric issues in patients with IBD.

Systematic review of the efficacy and safety of biological therapy for inflammatory conditions in HIV-infected individuals

Biologic therapies are injectable immunomodulatory agents directed against specific immune cell or chemical targets. They have transformed the lives of HIV-uninfected individuals with severe inflammatory conditions including psoriasis, rheumatoid arthritis, and ulcerative colitis. The perceived increased infection risk associated with these agents means that HIV-infected individuals have not been included in randomised control trials of these drugs. The literature for use of biologic therapies in HIV-infected populations is limited to case reports and case series. There are additional data on use of rituximab, a monoclonal antibody against B lymphocytes, in the setting of HIV-associated haematological malignancy. We performed a systematic review of efficacy and safety of biologic therapy for inflammatory conditions in HIV-infected individuals. Our systematic review identified 37 treatment episodes with six different biologic agents encompassing 10 different inflammatory conditions. Broadly, efficacy of the agents studied was comparable to reports from HIV-uninfected patients. Both infectious and non-infectious sequelae were also comparable with trial data from HIV-uninfected patients. HIV control, even for the minority of individuals not receiving anti-retroviral therapy (ART) at the time of biologic therapy, was not adversely affected. However, detail was limited concerning ART regimens and both immunological and virological parameters of follow-up. Overall available literature is of very low quality and likely subject to publication bias of successful cases. Firm conclusions are not possible regarding the efficacy and safety of biologic agents in HIV-infected individuals; however, there appear to be sufficient data to warrant inclusion of individuals with well-controlled HIV in future trial studies.

Treatment of psoriasis with etanercept in immunocompromised patients: Two case reports

Tumour necrosis factor (TNF)-α blocking agents have revolutionized the treatment of psoriasis and psoriatic arthritis. Concerns remain about increased susceptibility to infection and onset of malignancies, and the use of TNF-α agents in patients with HIV infection or undergoing immunosuppressant treatment is debated. We report cases of severe plaque psoriasis in a patient with HIV infection and in a liver transplant recipient who were successfully treated with etanercept, an anti-TNF-α agent, without notable side-effects.

What is the best way to manage screening for infections and vaccination of inflammatory bowel disease patients?

The use of biological agents and immunomodulators for inflammatory bowel disease (IBD) is associated with an increased risk of opportunistic infections, in particular of viral or bacterial etiology. Despite the existence of international guidelines, many gastroenterologists have not adopted routine screening and vaccination in those patients with IBD, which are candidate for biologic therapy. Available strategies to screen, diagnose and prevent bacterial and viral infections in patients with IBD prior to start biological therapy are discussed in this review.

NASPGHAN Clinical Report: Surveillance, Diagnosis, and Prevention of Infectious Diseases in Pediatric Patients With Inflammatory Bowel Disease Receiving Tumor Necrosis Factor-α Inhibitors

Children and adolescents with inflammatory bowel disease (IBD) receiving therapy with tumor necrosis factor α inhibitors (anti-TNFα) pose a unique challenge to health care providers in regard to the associated risk of infection. Published experience in adult populations with distinct autoinflammatory and autoimmune diseases treated with anti-TNFα therapies demonstrates an increased risk of serious infections with intracellular bacteria, mycobacteria, fungi, and some viruses; however, there is a paucity of robust pediatric data. With a rising incidence of pediatric IBD and increasing use of biologic therapies, heightened knowledge and awareness of infections in this population is important for primary care pediatricians, pediatric gastroenterologists, and infectious disease (ID) physicians. This clinical report is the result of a consensus review performed by pediatric ID and gastroenterology physicians detailing relevant published literature regarding infections in pediatric patients with IBD receiving anti-TNFα therapies. The objective of this document is to provide comprehensive information for prevention, surveillance, and diagnosis of infections based on current knowledge, until additional pediatric data are available to inform evidence-based recommendations.

Osteoarticular manifestations associated with HIV infection

About 150,000 people are HIV-positive in France, and the number of new cases is estimated at 7000-8000 per year, with no tendency to diminish over time. Admissions of HIV-positive patients have been decreasing, in contrast, since 2008, reflecting the dramatic improvements in quality of life and survival provided by triple antiretroviral regimens. HIV infection is now a chronic disease that exposes patients to the virus and antiretroviral drugs for many years. One consequence has been the emergence of new health conditions in HIV-positive patients, such as tumors, cardiovascular disease, and osteoarticular complications. These epidemiological and clinical changes have made it necessary for rheumatologists to learn about the osteoarticular abnormalities associated with the HIV, which they are likely to encounter at some point during their everyday practice. Osteoporosis is one such abnormality, and this review article starts with a discussion of the literature on this topic. Bone loss is common, chiefly in males. Multiple factors are involved. Studies have demonstrated an increase in the fracture risk and, consequently, recommendations about the screening and treatment of osteoporosis have been issued. The focus of this review article then turns to the other rheumatic manifestations seen in HIV-positive patients, including osteomalacia, avascular necrosis, and inflammatory joint disease. Osteoarticular pain is frequently reported by HIV-positive patients. Identifying the cause is essential to determine the best treatment strategy. Interestingly, immunosuppressant drugs, and even biotherapies, have shown a good safety profile in these immunodeficient patients.

Rheumatoid arthritis in patients with HIV: management challenges

Over the past few decades, HIV has been transformed from a once-uniformly fatal disease to now a manageable but complex multisystem illness. Before highly active antiretroviral therapy (HAART), reports suggested that HIV-infected patients with rheumatoid arthritis (RA) would experience remission of their disease. It has now become clear that RA can develop in HIV-infected patients at any time, independent of HAART. Choosing the right medication to treat symptoms related to RA while avoiding excess weakening of the immune system remains a clinical challenge. Agents such as hydroxychloroquine and sulfasalazine might best balance safety with efficacy, making them reasonable first choices for therapy in HIV-infected patients with RA. More immune suppressing agents such as methotrexate may balance safety with efficacy, but data are limited. Corticosteroids such as prednisone may also be reasonable but could increase the risk of osteonecrosis. Among biologic response modifiers, tumor necrosis factor α inhibitors may balance safety with efficacy, but perhaps when HIV replication is controlled with HAART. Monitoring RA disease activity remains challenging as only one retrospective study has been published in this area. Those with HIV infection and RA can experience comorbidities such as accelerated heart disease and osteoporosis, a consequence of the chronic inflammatory state that each illness generates. Although HIV-infected patients are at risk for developing the immune reconstitution inflammatory syndrome when starting HAART, it appears that immune reconstitution inflammatory syndrome has a minimal effect on triggering the onset or the worsening of RA.

Tumor-necrosis factor impairs CD4(+) T cell-mediated immunological control in chronic viral infection

Persistent viral infections are characterized by the simultaneous presence of chronic inflammation and T cell dysfunction. In prototypic models of chronicity--infection with human immunodeficiency virus (HIV) or lymphocytic choriomeningitis virus (LCMV)--we used transcriptome-based modeling to reveal that CD4(+) T cells were co-exposed not only to multiple inhibitory signals but also to tumor-necrosis factor (TNF). Blockade of TNF during chronic infection with LCMV abrogated the inhibitory gene-expression signature in CD4(+) T cells, including reduced expression of the inhibitory receptor PD-1, and reconstituted virus-specific immunity, which led to control of infection. Preventing signaling via the TNF receptor selectively in T cells sufficed to induce these effects. Targeted immunological interventions to disrupt the TNF-mediated link between chronic inflammation and T cell dysfunction might therefore lead to therapies to overcome persistent viral infection.

Inflammatory arthritis in HIV positive patients: A practical guide

Background

Musculoskeletal manifestations of the human immunodeficiency virus (HIV) have been described since the outset of the global HIV epidemic. Articular syndromes that have been described in association with HIV include HIV-associated arthropathy, seronegative spondyloarthropathies (SPA) (reactive arthritis, psoriatic arthritis (PsA) and undifferentiated SPA), rheumatoid arthritis (RA) and painful articular syndrome.

Methods

We carried out a computer-assisted search of PubMed for the medical literature from January 1981 to January 2015 using the keywords HIV, acquired immune-deficiency syndrome, rheumatic manifestations, arthritis, spondyloarthropathy, anti-TNF and disease modifying antirheumatic drugs. Only English language literature was included and only studies involving adult human subjects were assessed.

Results

There are challenges in the management of inflammatory arthritis in patients who are HIV-positive, including difficulties in the assessment of disease activity and limited information on the safety of immunosuppressive drugs in these individuals.

Conclusions

This review focuses on the clinical characteristics of the inflammatory articular syndromes that have been described in association with HIV infection and discusses the therapeutic options for these patients.

Use of tumor necrosis factor (TNF) inhibitors in patients with HIV/AIDS

Patients with HIV and AIDS are living longer because of advancements in antiretroviral therapy. These patients are often susceptible to debilitating inflammatory disorders that are refractory to standard treatment. We discuss the relationship of tumor necrosis factor-alpha and HIV and then review 27 published cases of patients with HIV being treated with tumor necrosis factor-alpha inhibitors. This review is limited because no randomized controlled trials have been performed with this patient population. Regardless, we propose that reliable seropositive patients, who are adherent to medication regimens and frequent monitoring and have failed other treatment modalities, should be considered for treatment with tumor necrosis factor-alpha inhibitors.

2015 American College of Rheumatology Guideline for the Treatment of Rheumatoid Arthritis

OBJECTIVE

To develop a new evidence-based, pharmacologic treatment guideline for rheumatoid arthritis (RA).

METHODS

We conducted systematic reviews to synthesize the evidence for the benefits and harms of various treatment options. We used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology to rate the quality of evidence. We employed a group consensus process to grade the strength of recommendations (either strong or conditional). A strong recommendation indicates that clinicians are certain that the benefits of an intervention far outweigh the harms (or vice versa). A conditional recommendation denotes uncertainty over the balance of benefits and harms and/or more significant variability in patient values and preferences.

RESULTS

The guideline covers the use of traditional disease-modifying antirheumatic drugs (DMARDs), biologic agents, tofacitinib, and glucocorticoids in early (<6 months) and established (≥6 months) RA. In addition, it provides recommendations on using a treat-to-target approach, tapering and discontinuing medications, and the use of biologic agents and DMARDs in patients with hepatitis, congestive heart failure, malignancy, and serious infections. The guideline addresses the use of vaccines in patients starting/receiving DMARDs or biologic agents, screening for tuberculosis in patients starting/receiving biologic agents or tofacitinib, and laboratory monitoring for traditional DMARDs. The guideline includes 74 recommendations: 23% are strong and 77% are conditional.

CONCLUSION

This RA guideline should serve as a tool for clinicians and patients (our two target audiences) for pharmacologic treatment decisions in commonly encountered clinical situations. These recommendations are not prescriptive, and the treatment decisions should be made by physicians and patients through a shared decision-making process taking into account patients' values, preferences, and comorbidities. These recommendations should not be used to limit or deny access to therapies.

The Role of Biologic Therapies in Dermatology

Biologic therapy has dramatically changed the way medicine, and specifically dermatology, is practiced today. The use of biologic agents in dermatology is evolving, with psoriasis being the most common indication for which biologics are used currently. However, several other dermatologic diseases seem to be responsive to biologic therapy, and continuing research and development efforts are elucidating the benefit-risk profiles of various biologic medications in these dermatologic conditions. Although biologic agents have revolutionized the management of dermatologic conditions, cost must also be considered when evaluating management options, especially compared with traditional agents. For example, the cost of 1 year of induction and maintenance treatment of psoriasis in 2014 was estimated to be $53,909 for ustekinumab, $46,395 for etanercept, and $39,041 for adalimumab. Nonetheless, because of their efficacy, the cost of a biologic may be offset by significant reductions in the number of hospital stays, reduction in use of other systemic therapies, and increased satisfaction by patients.32 Thus, understanding their mechanisms of action, labeled and off-label uses in dermatology, and common adverse effects helps to inform clinical decision making and improve patient outcomes.

New treatment paradigms in psoriatic arthritis: an update on new therapeutics approved by the U.S. Food and Drug Administration

PURPOSE OF REVIEW

The purpose of this study is to give an overview of the new treatments approved by the U.S. Food and Drug Administration (FDA) for use in psoriatic arthritis (PsA).

RECENT FINDINGS

FDA has approved three new drugs for PsA: Certolizumab-pegol: a PEGylated Fc-free tumour necrosis factor inhibitor (TNFi); ustekinumab: an anti interleukin (IL)-12 and IL-23 mAb; and apremilast and oral phosphodiesterase 4 inhibitor. On well designed and extensive developing programmes, all three drugs proved to be effective for the treatment of most PsA manifestations, including peripheral arthritis, skin involvement, enthesitis, dactylitis, quality of life and radiographic progression in patients failing traditional disease modifying drugs (DMARDs) and TNFi. Safety profile of all three drugs seems to be reassuring until now, although long-term data are still not available. Although Certolizumab-pegol is likely to be placed among the other TNFi, ustekinumab and apremilast, due to lower efficacy on arthritis, are being more frequently used as second-line therapy after TNFi failure, especially among rheumatologists.

SUMMARY

There are new therapeutic options approved for the treatment of PsA. For the first time, well proved effective therapies with a different mechanism of action than the inhibition of TNF alpha are available for the treatment of this progressive disease.
