Annals of Indian Academy of Neurology May 2024To determine the factors, if any, that are associated with the efficacy of "off-label therapies" (OLTs) for multiple sclerosis (MS).
OBJECTIVE
To determine the factors, if any, that are associated with the efficacy of "off-label therapies" (OLTs) for multiple sclerosis (MS).
METHODS
Consecutive patients (N = 174) with relapsing-remitting MS (RRMS) or secondary progressive MS (SPMS) with relapses, on OLTs with a generic formulation of azathioprine, mycophenolate mofetil, or rituximab biosimilar for ≥2 years were included. Annualized relapse rate (ARR) and expanded disability status score (EDSS) 1 year before and ≥2 years after starting OLTs were recorded. Optical coherence tomography (OCT) was done at baseline and at the end of the study.
RESULTS
During a median period of 4.1 years (2.4-24), ARR reduced in all (P < 0.0001) and EDSS improved in RRMS (P < 0.0001) patients but not in SPMS (P < 0.31) patients. Good responders were those who had RRMS (P = 0.001, odds ratio [OR] 0.04, 95% confidence interval [CI] 0.01-0.15), female gender (P 0.008, OR 6.67, 95% CI 1.7-26.8), and had early access to OLT (P = 0.006, OR 1.2, 95% CI 1.05-1.40). Baseline peripapillary retinal nerve fiber layer thickness identified the risk of conversion to SPMS (P < 0.01, OR 1.03; 95% CI 1.01-1.06).
CONCLUSIONS
This limited prospective study suggests that early identification of patients who could potentially respond to unconventional but accessible therapies may be valuable in the treatment of MS, particularly in resource-poor regions.

Review
Autoimmune hepatitis (AIH) is a rare, chronic, inflammatory, and necrotic liver disease characterized by the presence of autoantibodies. Its etiology is unknown. It affects 1 in 200 000 people annually in the US and occurs predominantly in women. Its presentation varies from asymptomatic forms to cirrhosis and acute liver failure and its diagnosis is based on the measurement of autoantibodies, such as antinuclear autoantibodies (ANA), anti-smooth muscle antibodies (ASMA) and anti-liver and kidney microsomal antibodies (anti-LKM). 1). 10% of HAIs do not present antibodies, being called seronegative HAI, requiring a liver biopsy for diagnosis. To date the evidence remains limited and different societies have issued suggestions and recommendations. For this reason, we believe it is relevant to carry out a bibliographic review on the subject, capturing in this document the important information for the understanding and management of this pathology.

Thiopurines, an effective therapy for Crohn's disease (CD), often lead to adverse events (AEs). Gene polymorphisms affecting thiopurine metabolism may predict AEs. This retrospective study in CD patients (n = 114) with TPMT activity > 5 Units/Red Blood Cells analyzed TPMT (c.238 G > C, c.460 G > A, c.719 A > G), ITPA (c.94 C > A, IVS2 + 21 A > C), and NUDT15 (c.415 C > T) polymorphisms. All patients received azathioprine (median dose 2.2 mg/kg) with 41.2% experiencing AEs, mainly myelotoxicity (28.1%). No NUDT15 polymorphisms were found, 7% had TPMT, and 31.6% had ITPA polymorphisms. AEs led to therapy modifications in 41.2% of patients. Multivariate analysis identified advanced age (OR 1.046, p = 0.007) and ITPA IVS2 + 21 A > C (OR 3.622, p = 0.015) as independent predictors of AEs. IVS2 + 21 A > C was also associated with myelotoxicity (OR 2.863, p = 0.021). These findings suggest that ITPA IVS2 + 21 A > C polymorphism and advanced age predict AEs during thiopurine therapy for CD with intermediate-normal TPMT activity.

Review
BACKGROUND
Hepatic sarcoidosis is an uncommon clinical condition in which clear recommendations are lacking in its treatment. We aimed to review systematically the literature on hepatic sarcoidosis treatment to guide clinicians.
METHODS
Using MEDLINE, PubMed, CINAHL, Cochrane Library, and Google Scholar databases, we searched original articles on clinical studies reporting the outcome of adult hepatic sarcoidosis patients following treatment with various pharmacological agents. The primary end point was focused on assessing symptomatic relief and biochemical improvement posttreatment.
RESULTS
Out of 614 retrieved references, 34 published studies were eligible, providing data for a total of 268 patients with hepatic sarcoidosis. First-line therapy with corticosteroids alone was reported in 187 patients, whilst ursodeoxycholic acid (UDCA) was used in 40 patients. Symptomatic and biochemical responses were reported among 113(60.4%) and 80(42.8%) cases of corticosteroids respectively, whereas UDCA showed a complete response in 23(57.5%) patients. Second-line therapy was used in steroid-refractory cases, with most cases being reported for azathioprine ( = 32) and methotrexate ( = 28). Notably, 15(46.9%) and 11(39.2%) patients showed both clinical and biochemical responses respectively. Biological therapy including anti-tumor necrosis factor (anti-TNF) was used as third line therapy in twelve cases with a 72.7% symptomatic and biochemical response rate each.
CONCLUSION
The quality of evidence for the treatment of hepatic sarcoidosis was poor. Nevertheless, it appears that corticosteroid or UDCA may be utilized as first-line therapy. For cases that are refractory to corticosteroids, steroid-sparing immunosuppressive agents and anti-TNF have shown some promising results, but further high-quality studies are required.

Stricture formation is common in Crohn's disease, and endoscopic intervention plays an increasingly important role in managing these strictures. A 61-year-old man with biological aortic prosthesis and a 30-year history of ileocolonic stricturing Crohn's disease, managed with azathioprine and infliximab, presented with marked occlusive symptoms. Colonoscopy revealed a descending colon stricture, prompting endoscopic balloon dilation. At the time of the procedure, no prophylactic antibiotic was given. Subsequently, he developed Streptococcus gallolyticus endocarditis, necessitating aortic valve replacement. The authors present a case of late endocarditis associated with endoscopic balloon dilation of a Crohn-related colonic stricture.

INTRODUCTION/AIMS
Efgartigimod, a neonatal Fc-receptor inhibitor, has recently been approved as treatment for myasthenia gravis (MG). In this retrospective cohort study, we aimed to systematically assess short- and long-term effectiveness of efgartigimod in patients with refractory MG.
METHODS
Sixteen patients with refractory autoimmune acetylcholine receptor MG were treated with efgartigimod. Data were collected from January 2021 to March 2023 on Myasthenia Gravis Activities of Daily Living (MG-ADL), Quantitative Myasthenia Gravis score (QMG), Myasthenia Gravis Composite score (MGC) and the 15-item revised version of the Myasthenia Gravis Quality of Life questionnaire (MG-QoL15r).
RESULTS
A favorable outcome was seen in 56% of patients at the last measurement. Out of 16 patients, 50% were an MG-ADL responder after the first treatment cycle. After 4 weeks, a clinically meaningful improvement compared to baseline was seen on the MG-ADL, QMG, and MGC. There was a statistically significant improvement on the MGQoL15r from baseline to week 4. The improvement was maintained until the last measurement for the MGC and the MGQoL15r. At the last visit, all patients had discontinued 4-weekly dosages, shifting to administration frequencies of 1, 2, or 3 weeks. Drug doses could be decreased for prednisolone (n = 7), azathioprine (n = 2), and intravenous immunoglobulin (n = 9). Frequency of plasma exchange was decreased in nine patients.
DISCUSSION
In patients with refractory MG, efgartigimod was effective for at least half of all patients. Patients required more frequent dosing compared to the ADAPT phase 3 trial. In 80% of the patients concurrent medication could be reduced or discontinued.

: In the context of a comparative study of efficacy and safety of drugs used in rare neuromuscular and neurodegenerative diseases (CAESAR-call AIFA_FV_2012-13-14), we assessed the use patterns of drugs indicated for myasthenia gravis (MG). : A retrospective cohort study was conducted based on administrative healthcare data. For a cohort of MG patients, prevalent and incident use of pyridostigmine (Py) and other indicated drugs in the first year after case identification was evaluated. Prevalent combined use of major therapies (azathioprine (Az), prednisone (Pr), vitamin D (Vd)) stratified by Py use was assessed, and a comparison between therapies at the time of MG identification and during the first year of follow-up was performed. : We included 2369 MG patients between 2013 and 2019. Among them, prevalent and incident Py users were 38.4% and 22.0%, respectively. In the first year of follow-up, the use of Pr was observed in 74.5% of Py prevalent users and in 82.0% of Py incident users, respectively; the use of Az was observed in 24.9% and 23.0%, respectively; and the use of Vd was observed in 53.3% and 48.2%, respectively. Among 910 Py prevalent users, 13.1% also used Az, Pr, and Vd, while 15.3% used none of these. Among 938 non-Py users, 2.7% used Az, Pr, and Vd, while 53.8% used none of these. During the first year, an increase in combined therapies was evident in incident Py users. : Our results suggest that, for some MG patients, there may be a need for treatments that combine a rapid onset of benefit with long-term and consistent disease control. These issues may be addressed by the new treatments currently being developed. To date, more studies are needed to address the heterogeneity, quality, and generalizability of the existing data and to evaluate patterns of use, efficacy, and safety of new or emerging therapies for MG.

Advances in Rheumatology (London,... Jun 2024To develop the second evidence-based Brazilian Society of Rheumatology consensus for diagnosis and treatment of lupus nephritis (LN).
OBJECTIVE
To develop the second evidence-based Brazilian Society of Rheumatology consensus for diagnosis and treatment of lupus nephritis (LN).
METHODS
Two methodologists and 20 rheumatologists from Lupus Comittee of Brazilian Society of Rheumatology participate in the development of this guideline. Fourteen PICO questions were defined and a systematic review was performed. Eligible randomized controlled trials were analyzed regarding complete renal remission, partial renal remission, serum creatinine, proteinuria, serum creatinine doubling, progression to end-stage renal disease, renal relapse, and severe adverse events (infections and mortality). The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to develop these recommendations. Recommendations required ≥82% of agreement among the voting members and were classified as strongly in favor, weakly in favor, conditional, weakly against or strongly against a particular intervention. Other aspects of LN management (diagnosis, general principles of treatment, treatment of comorbidities and refractory cases) were evaluated through literature review and expert opinion.
RESULTS
All SLE patients should undergo creatinine and urinalysis tests to assess renal involvement. Kidney biopsy is considered the gold standard for diagnosing LN but, if it is not available or there is a contraindication to the procedure, therapeutic decisions should be based on clinical and laboratory parameters. Fourteen recommendations were developed. Target Renal response (TRR) was defined as improvement or maintenance of renal function (±10% at baseline of treatment) combined with a decrease in 24-h proteinuria or 24-h UPCR of 25% at 3 months, a decrease of 50% at 6 months, and proteinuria < 0.8 g/24 h at 12 months. Hydroxychloroquine should be prescribed to all SLE patients, except in cases of contraindication. Glucocorticoids should be used at the lowest dose and for the minimal necessary period. In class III or IV (±V), mycophenolate (MMF), cyclophosphamide, MMF plus tacrolimus (TAC), MMF plus belimumab or TAC can be used as induction therapy. For maintenance therapy, MMF or azathioprine (AZA) are the first choice and TAC or cyclosporin or leflunomide can be used in patients who cannot use MMF or AZA. Rituximab can be prescribed in cases of refractory disease. In cases of failure in achieving TRR, it is important to assess adherence, immunosuppressant dosage, adjuvant therapy, comorbidities, and consider biopsy/rebiopsy.
CONCLUSION
This consensus provides evidence-based data to guide LN diagnosis and treatment, supporting the development of public and supplementary health policies in Brazil.

Hypertrophic discoid lupus erythematosus is a rare variant of chronic cutaneous lupus erythematosus and is often challenging to treat. A male in his early 60s presented with diffuse erythematous, crusty, pruritic plaques on his upper and lower extremities, face, upper back, dorsal aspect of the hands and chest. He also described prolonged morning stiffness, swelling of his fingers and wrists, oral sores and Raynaud's phenomenon. He was positive for antinuclear antibody and anti-SSA antibody and had low C3 and C4 proteins. The skin biopsy was consistent with hypertrophic discoid lupus erythematosus. He was diagnosed with systemic lupus erythematosus. Skin lesions were refractory to treatment with topical corticosteroids, topical acitretin, hydroxychloroquine, azathioprine or mycophenolate. Anifrolumab infusions were initiated with a near-complete resolution of cutaneous symptoms within 3 months.

Advancements in surgical techniques and the optimization of immunosuppression have boosted organ transplant survival rates; however, liver transplant recipients still risk complications such as hepatic vein occlusive disease (HVOD), also called sinusoidal obstruction syndrome. Rare but potentially fatal HVOD damages endothelial cells due to factors like chemotherapy, stem cell transplantation, and certain medications such as azathioprine and tacrolimus. Typically, HVOD presents with distinct clinical symptoms, including ascites, jaundice, and significant weight gain. Herein, we present the case of a 66-year-old male with decompensated liver cirrhosis due to hepatitis C virus infection. The patient underwent a deceased donor liver transplantation at our center. Unfortunately, 4 months after the transplant, he experienced progressive dyspnea and developed right pleural effusion. Abdominal computed tomography and a liver biopsy confirmed the diagnosis of HVOD, likely induced by tacrolimus. After stopping tacrolimus, we observed a significant decrease in ascites and remission of the patient's clinical symptoms of abdominal distention and dyspnea; subsequently, we introduced cyclosporine. In this report, we describe this specific patient's case and discuss HVOD, including its diagnosis and management.
