Assessing risk of liver enzyme elevation in patients with immune-mediated diseases and different hepatitis B virus serostatus receiving anti-TNF agents: a nested case-control study

Prognostic factors for liver, blood and kidney adverse events from glucocorticoid sparing immune-suppressing drugs in immune-mediated inflammatory diseases: a prognostic systematic review

BACKGROUND

Immune-suppressing drugs can cause liver, kidney or blood toxicity. Prognostic factors for these adverse-events are poorly understood.

PURPOSE

To ascertain prognostic factors associated with liver, blood or kidney adverse-events in people receiving immune-suppressing drugs.

DATA SOURCES

MEDLINE, Web of Science, EMBASE and the Cochrane library (01 January 1995 to 05 January 2023), and supplementary sources.

DATA EXTRACTION AND SYNTHESIS

Data were extracted by one reviewer using a modified CHARMS-PF checklist and validated by another. Two independent reviewers assessed risk of bias using Quality in Prognostic factor Studies tool and assessed the quality of evidence using a Grading of Recommendations Assessment, Development and Evaluation-informed framework.

RESULTS

Fifty-six studies from 58 papers were included. High-quality evidence of the following associations was identified: elevated liver enzymes (6 studies) and folate non-supplementation (3 studies) are prognostic factors for hepatotoxicity in those treated with methotrexate; that mercaptopurine (vs azathioprine) (3 studies) was a prognostic factor for hepatotoxicity in those treated with thiopurines; that mercaptopurine (vs azathioprine) (3 studies) and poor-metaboliser status (4 studies) were prognostic factors for cytopenia in those treated with thiopurines; and that baseline elevated liver enzymes (3 studies) are a prognostic factor for hepatotoxicity in those treated with anti-tumour necrosis factors. Moderate and low quality evidence for several other demographic, lifestyle, comorbidities, baseline bloods/serologic or treatment-related prognostic factors were also identified.

LIMITATIONS

Studies published before 1995, those with less than 200 participants and not published in English were excluded. Heterogeneity between studies included different cut-offs for prognostic factors, use of different outcome definitions and different adjustment factors.

CONCLUSIONS

Prognostic factors for target-organ damage were identified which may be further investigated for their potential role in targeted (risk-stratified) monitoring.

Treatment or Prophylaxis against Hepatitis B Virus Infection in Patients with Rheumatic Disease Undergoing Immunosuppressive Therapy: An Update

Chronic hepatitis B virus (HBV) flares or reactivations are serious causes of morbidity or mortality in rheumatologic patients undergoing immunosuppressive therapy. The recent insights in the pathogenesis of rheumatic diseases led to the use of new immunosuppressive therapies indicated in case of failure, partial response, or intolerance of conventional synthetic disease-modifying anti-rheumatic drugs. Based on these premises, this review examines and discusses the main rheumatologic treatments that could require the initiation of prophylactic treatment or close monitoring of occult HBV infection in patients beginning antiviral therapy at the first signs of HBV reactivation, or antiviral treatment in chronic HBV-infected patients. We searched for relevant studies published in the last five years. Studies suggested that the presence of HBV infection is common in rheumatic patients and HBV reactivation during these immunosuppressant treatments is quite frequent in these kinds of patients. Therefore, before starting an immunosuppressive therapy, patients should be screened for HBsAg, anti-HBs, and anti-HBc and, on the basis of markers positivity, they should be carefully characterized for HBV infection phases. In conclusion, screening of HBV infection in patients undergoing immunosuppressive therapy with subsequent HBV monitoring, prophylaxis or treatment consistently reduces the risk of clinical consequences.

Practical recommendations for systemic treatment in psoriasis in case of coexisting inflammatory, neurologic, infectious or malignant disorders (BETA-PSO: Belgian Evidence-based Treatment Advice in Psoriasis; part 2)

Background

Psoriasis patients carry an increased risk for associated comorbidities. Dermatologists have to be aware of the effects of systemic treatments not only on psoriasis but also on co‐occurring diseases. In case of other coexisting inflammatory diseases, the right psoriasis treatment may improve both disorders. For infectious and malignant disorders, some treatments have to be avoided as they may be harmful.

Objective

The primary objective of this project was to collect evidence for the creation of practice guidelines for systemic treatment of psoriasis (BETA‐PSO: Belgian Evidence‐based Treatment Advice in Psoriasis).

Methods

Evidence‐based recommendations were formulated using a quasi‐Delphi methodology after a systematic search of the literature and a consensus procedure involving eight psoriasis experts.

Results

Recommendations are given on the use of systemic treatment in psoriatic arthritis, inflammatory bowel disease, demyelinating disorders, hepatitis B and C, HIV and cancer.

Conclusion

This expert opinion is a practical guide for dermatologists when handling psoriasis patients with these specific conditions.
