Hepatitis B reactivation in psoriasis patients treated with anti-TNF agents: prevention and management

Management of Psoriasis Patients with Serious Infectious Diseases

The management of patients affected by moderate-to-severe psoriasis may be challenging, in particular in patients with serious infectious diseases [tuberculosis (TB), hepatitis B and C, HIV, COVID-19]. Indeed, these infections should be ruled out before starting and during systemic treatment for psoriasis. Currently, four conventional systemic drugs (methotrexate, dimethyl fumarate, acitretin, cyclosporine), four classes of biologics (anti-tumour necrosis factor alpha, anti-interleukin (IL)12/23, anti-IL-17s, and anti-IL-23], and two oral small molecules (apremilast, deucravacitinib) have been licensed for the treatment of moderate-to-severe psoriasis. Each of these drugs is characterized by a unique safety profile which should be considered before starting therapy. Indeed, some comorbidities or risk factors may limit their use. In this context, the aim of this manuscript was to evaluate the management of patients affected by moderate-to-severe psoriasis with serious infectious diseases.

Safety of secukinumab in the treatment of patients with axial spondyloarthritis and concurrent hepatitis B virus infection or latent tuberculosis infection

OBJECTIVE

To evaluate the safety of secukinumab (SEC) in the treatment of patients with axial spondyloarthritis (axSpA) and concurrent hepatitis B virus (HBV) infection or latent tuberculosis infection (LTBI).

METHODS

This is a retrospective cohort study. Adult axSpA patients with HBV infection or LTBI receiving SEC treatment for at least 3 months from March 2020 to July 2022 in Guangdong Provincial People's Hospital were included. Patients were screened for HBV infection and LTBI before SEC treatment. During follow-up, reactivation of HBV infection and LTBI was monitored. Relevant data were collected and analyzed.

RESULTS

A total of 43 axSpA patients with HBV infection or LTBI were included, of whom 37 were with HBV infection, 6 were with LTBI. Six out of thirty-seven (16.2%) patients with axSpA and concurrent HBV infection exhibited HBV reactivation after 9.0 ± 5.7 months of SEC treatment. Among them, 3 patients had chronic HBV infection and received anti-HBV prophylaxis, 2 patients had chronic HBV infection but did not receive anti-HBV prophylaxis, and 1 patient had occult HBV infection and did not receive antiviral prophylaxis. None of the 6 axSpA patients with LTBI developed reactivation of LTBI, whether received anti-TB prophylaxis or not.

CONCLUSIONS

HBV reactivation can occur in axSpA patients with different types of HBV infection undergoing SEC treatment, whether receive antiviral prophylaxis or not. Close monitoring of HBV reactivation in axSpA patients with HBV infection undergoing SEC treatment is mandatory. Anti-HBV prophylaxis may be beneficial. In contrast, SEC may be safe in axSpA patients with LTBI, even in patients not receiving anti-TB prophylaxis. Key Points •Currently, most evidence about the safety of SEC in patients with HBV infection and LTBI were from patients with psoriasis. Our study adds data about the safety of SEC in Chinese axSpA patients with concurrent HBV infection or LTBI in real-world clinical setting. •Our study showed that HBV reactivation can occur in axSpA patients with different types of HBV infection undergoing SEC treatment, whether receive antiviral prophylaxis or not. •Close monitoring of serum HBV markers, HBV DNA load, and liver function is mandatory in axSpA patients with chronic, occult, and resolved HBV infection undergoing SEC treatment. Anti-HBV prophylaxis may be beneficial in all HBsAg-positive patients and HBsAg-negative, HBcAb-positive patients at high risk of HBV reactivation who are receiving SEC therapy. •None of the axSpA patients with LTBI, whether received anti-TB prophylaxis or not, developed reactivation of LTBI in our study. SEC may be safe in axSpA patients with LTBI, even in patients not receiving anti-TB prophylaxis.

Network-based pharmacology and molecular docking exploring the "Bupleuri Radix-Scutellariae Radix" mechanism of action in the viral hepatitis B treatment

Viral hepatitis B is caused by the hepatitis B virus, which is characterized by liver lesions. Bupleuri Radix and Scutellariae Radix are the main traditional medicine pairs with remarkable efficacy in hepatitis B. However, their molecular mechanisms are incompletely understood. The main active components of Bupleuri Radix and Scutellariae Radix, as well as therapeutic targets for the treatment of hepatitis B, were identified through network pharmacology techniques. We identified viral hepatitis B targets using the GeneCards, online mendelian inheritance in man, and therapeutic target databases. We discovered the active components of Bupleuri Radix and Scutellariae Radix as well as therapeutic targets using the encyclopedia of traditional Chinese medicine, HERB, traditional Chinese medicine systems pharmacology database, and a bioinformatics analysis tool for molecular mechanism of traditional Chinese medicine databases. VENNY obtained the intersections. Cytoscape and STRING were used to create the "active ingredient-potential target" network and protein interaction network. The DAVID database was used to enrich GO and KEGG pathways. The results were confirmed using the molecular docking method. There were 1827 viral hepatitis B targets, and 37 active ingredients for Bupleuri and Scutellariae Radix, with the main components being quercetin, wogonin, baicalein, and kaempferol. Tumor necrosis factor (TNF), mitogen-activated protein kinase 3 (MAPK3), interleukin-6 (IL-6), vascular endothelial growth factor A, cysteinyl aspartate specific proteinase 3, transcription factor AP-1 (JUN), RAC-alpha serine/threonine-protein kinase, and cellular tumor antigen p53 are among the 78 common targets of Bupleuri Radix and Scutellariae Radix intervention in viral hepatitis B. KEGG enrichment resulted in 107 pathways, including cancer, hepatitis B, and TNF signaling pathways. According to the molecular docking technique, quercetin, wogonin, baicalein, and kaempferol had strong binding activities with TNF, MAPK3, and IL-6. In this study, we initially identified various molecular targets and multiple pathways involved in hepatitis B treatment with Bupleuri Radix and Scutellariae Radix.

Hepatitis Virus Reactivation in Patients with Psoriasis Treated with Secukinumab in a Real-World Setting of Hepatitis B or Hepatitis C Infection

BACKGROUND AND OBJECTIVE

Biologics for psoriasis, especially anti-tumor necrosis factor-α therapies, may reactivate hepatitis B virus (HBV) or hepatitis C virus (HCV) infections, as well in inactive carriers or patients with occult infection. However, some biologics, including anti-interleukin-17 therapies such as secukinumab, seem to be less likely to cause hepatitis reactivation. This study assessed the safety of secukinumab treatment in patients with psoriasis with HBV or HBC infection.

METHODS

This was a retrospective cohort study of patients with moderate-to-severe psoriasis treated with secukinumab at seven Italian centers. Patients serologically positive for one or more of the following viral hepatitis markers were included: HCV antibody (± HCV-RNA positivity) and/or hepatitis B surface antigen, and/or HBV core antibody and/or HBV surface antibody (± HBV-DNA positivity). Patients received secukinumab 300 mg subcutaneously at week 0/1/2/3/4 then every 4 weeks; prophylactic therapy before starting secukinumab was prescribed where indicated. The primary study endpoint was the reactivation of hepatitis viral infection, defined as conversion to HBV-DNA or HCV-RNA positivity, with or without elevation of transaminases.

RESULTS

Sixty patients (17 with concomitant psoriatic arthritis) were included. Thirteen subjects were hepatitis B surface antigen positive, 19 were HBV core antibody positive, and 30 were positive for the HCV antibody; however, all were HCV-RNA negative. After 53.5 ± 37.5 weeks of secukinumab therapy, hepatitis reactivation occurred in only one patient, who had a reactivation of both hepatitis B and hepatitis C. This patient had not undergone hepatitis B prophylaxis or hepatitis C treatment before secukinumab.

CONCLUSIONS

These real-world data support the safety of secukinumab in patients with positive markers of HBV or HCV infection, when administered together with dedicated prophylaxis.

Risk of hepatitis B reactivation: From biologic therapies for psoriasis to immunosuppressive therapies for COVID‑19 (Review)

The cytokine storm from the evolution of severe cases of COVID-19, requiring strong immunosuppressive therapies, has raised the issue of reactivation of hepatitis B virus (HBV) infections in these patients. An analysis of the first observational studies in patients with COVID-19 and immunosuppressive therapy and HBV infection along with special clinical cases was presented, as well as personal experience on a series of cases (a group of 958 patients with COVID-19), compared with the analysis of studies performed on patients with HBV infection that underwent biological therapies for psoriasis and personal experience (a group of 81 psoriasis patients treated with biological therapies). Clinical studies have revealed that HBV reactivation in patients undergoing biological therapies for psoriasis, can be prevented with monitoring and treatment protocols and thus, these therapies have been demonstrated to be safe and effective. In COVID-19, immunosuppressive therapies are short-lived but in high doses, and the conclusions of clinical trials are contradictory, but there are published cases of HBV reactivation, which requires a unitary attitude in the prevention of HBV reactivation in these patients. An algorithm was presented for monitoring and treatment of HBV infection for patients with psoriasis treated with biological therapy and the conditions when this protocol can be used for patients with COVID-19 and immunosuppressive therapy.

Safety of therapies using ustekinumab in patients with psoriasis who have had hepatitis B virus infection

Biological therapies used in psoriasis treatment pose a risk of reactivation of hepatitis B virus (HBV) infection. This risk occurs not only in patients with HB surface antigen (HBsAg) (+) but also in patients with past or occult HBV infection (with negative HBsAg, positive HB core antibodies (HBcAb), and positive HBV deoxyribonucleic acid [DNA]). Ustekinumab (UST) is a biologic agent acts by blocking the IL-12/23 pathway. Thus, hindering this response may lead to HBV reactivation. UST therapy is associated with mild HBV-r risk; however, there is insufficient data to confirm that hypothesis. Herein, we present observations on the safety of UST therapy in patients with psoriasis and serologically proved past HBV infection. One-hundred and six consecutive patients with moderate to severe psoriasis treated with biological therapy between May 2013 and January 2020 were retrospectively analyzed. Out of 106 patients, there were five who reported having past HBV. Those five patients were tested for the presence of HBsAg, HBcAb, HBsAb as well as HBV DNA at baseline and at the end of the follow-up period. HBV reactivation was defined as changing of "undetectable" to "detectable" viremia. All five patients were treated with UST. Five patients in our cohort group were found to have resolved HBV infection: HBsAg (-), HBcAb (+), and HBV DNA (-); 4/5 were HBsAb (+) and 1/5 HBsAb (-). None of the patients experienced an increase in their liver function tests values and no signs of hepatitis or HBV reactivation were observed at any point during the study. All the patients were HBsAg and HBV DNA negative at the end of the follow-up period. The average treatment time was 82.4 (28, 96) weeks. The average follow-up time was 75.2 (31, 176) weeks. Based on the available literature and the results from our observations, UST therapy seems to be a safe option for patients with resolved HBV infection.

A single-centre, observational, retrospective, real-life study evaluating adalimumab biosimilar ABP 501 in the treatment of plaque-type psoriasis and psoriatic arthritis in originator-naïve patients and in patients undergoing non-medical switch from originator

BACKGROUND

ABP 501 is a biosimilar to the anti-tumor necrosis factor-alfa monoclonal antibody adalimumab and despite its effectiveness and safety in the treatment of psoriasis was demonstrated in randomized clinical trials, no real-life data are available, in particular in patients undergoing non-medical switch from originator to biosimilar.

METHODS

We retrospectively searched our clinical records for all patients receiving ABP 501 between March 10, 2019 and September 7, 2019 at our Department. Therefore, we identified 94 patients, 46 patients underwent non-medical switch from adalimumab reference product to ABP 501.

RESULTS

In originator-naïve patients, mean PASI significantly improved from baseline to week 24 (p < .0001) in both Pso and PsA cohorts. In these patients, mean DAS-28 ESR improved with no significant differences from baseline. In patients undergoing non-medical switch from adalimumab reference product to ABP 501, no significant difference in PASI or DAS-28 ESR were observed from week 16 before switch to week 24 after switch.

CONCLUSIONS

AB- 501 is an effective treatment for plaque-type psoriasis and psoriatic arthritis regardless if patients are originator-naïve or if they were switched from the reference product.

Successful therapy of plaque-type psoriasis with secukinumab in patients with multiple comorbidities treated with previous biologic therapies

PURPOSE

Biologic therapy in psoriatic patients with multiple comorbidities is challenging due to worsening of associated diseases and possible side effects of concomitant medications.

MATERIALS AND METHODS

We describe three patients with multiple comorbidities documenting successful treatment of psoriasis with secukinumab following failure of multiple conventional and biologic DMARDs.

RESULTS

The first case is an obese 59-year-old woman (HBV + with latent tuberculosis) with arterial hypertension and 12-year history of breast cancer. The second is a 45-year-old obese man (HCV + with occult HBV infection on therapy with multiple antipsychotics and taking methadone for opioid dependence), while the last is a 39-year-old man with severe obesity, non-alcoholic hepatosteatosis, and NYHA class II heart failure. All three patients had undergone previous conventional (methotrexate, cyclosporine, retinoids, and phototherapy) and multiple biologic treatments (one or more of the following: adalimumab, ustekinumab, etanercept, infliximab originator, and biosimilar) that were discontinued for inefficacy and/or adverse effects. All patients underwent therapy with secukinumab, which was associated with sustained clinical benefits and no clinically relevant safety findings.

CONCLUSIONS

The present three cases add further evidence that secukinumab is effective and well tolerated in difficult to treat psoriatic patients with multiple comorbidities, namely HBV, latent TBC infection, and hepatic impairment.

INASL Guidelines on Management of Hepatitis B Virus Infection in Patients receiving Chemotherapy, Biologicals, Immunosupressants, or Corticosteroids

Hepatitis B Virus (HBV) reactivation in patients receiving chemotherapy, biologicals, immunosupressants, or corticosteroids is emerging to be an important cause of morbidity and mortality in patients with current or prior exposure to HBV infection. These patients suffer a dual onslaught of illness: one from the primary disease for which they are receiving the culprit drug that led to HBV reactivation, and the other from HBV reactivation itself. The HBV reactivation not only leads to a compromised liver function, which may culminate into hepatic failure; it also adversely impacts the treatment outcome of the primary illness. Hence, identification of patients at risk of reactivation before starting these drugs, and starting treatment aimed at prevention of HBV reactivation is the best strategy of managing these patients. There are no Indian guidelines on management of HBV infection in patients receiving chemotherapy, biologicals, immunosupressants, or corticosteroids for the treatment of rheumatologic conditions, malignancies, inflammatory bowel disease, dermatologic conditions, or solid-organ or bone marrow transplantation. The Indian National Association for Study of the Liver (INASL) had set up a taskforce on HBV in 2016, with a mandate to develop consensus guidelines for management of various aspects of HBV infection, relevant to India. In 2017 the taskforce had published the first INASL guidelines on management of HBV infection in India. In the present guidelines, which are in continuation with the previous guidelines, the issues on management of HBV infection in patients receiving chemotherapy, biologicals, immunosupressants, or corticosteroids are addressed.
