Introduction

Eculizumab (Soliris) is a fully humanized long-acting IgG2/IgG4 monoclonal antibody that inhibits the terminal complement protein C5.[1] It works by preventing its cleavage into C5a which increases the permeability of blood vessels and attracts inflammatory cells by chemotaxis and C5b which coordinates the membrane attack.[2][3] Eculizumab is known to be effective in reducing the frequency of relapse in highly clinically active AQP4-IgG–positive neuromyelitis optica (NMO).[4][5] It provided the first FDA-approved treatment for neuromyelitis optica spectrum disorder (NMOSD) with positive AQP4-IgG and has drastically changed the natural history of patients with NMOSD.[6]

While the survival benefit of Solaris in the setting of NMOSD is undeniable, as occurs with all proteins, there is a potential for immunogenicity.[7] Surprisingly, very few cases of lupus reactivation by Eculizumab have been reported. Literature review using PubMed and MEDLINE using discoid lupus erythematosus and/or eculizumab, retrieved cero case-reports. According to a trial performed by Pittock et. al., the most common adverse effects of using eculizumab in patients with NMO were found to be upper respiratory infections (28%) and headache (22%).[8] Overall, the percentage of patients treated with Eculizumab (for any disease) that develope rash ranges between 10-15%.[9]

Here, we report the case of a 75-year-old female with onset of cutaneous discoid lupus erythematosus after the intravenous administration of the IgG2/IgG4 monoclonal antibody eculizumab, which was initiated for the treatment of IgG–positive neuromyelitis optica.

Case Presentation

A 75-year-old (race?) female presented for evaluation of an asymptomatic rash in her extremeties. Her past medical history was significant for discoid lupus erythematosus diagnosed (when?) achieving drug-induced remission with (treatment?) and (any other commorbidity?). Other chronic medications included (medications?). She was diagnosed with neuromyelitis optica (subtype) one year earlier and was initially managed with Rituximab by another provider. When she arrived to the clinic, physical examination showed residual bilateral numbness from the chest down to the extremities, strength was (description?), in addition to residual vision loss (what type of vision loss?) from a previous optic neuritis attack. No dermatologic lesions were observed. Her last labs exhibited (CBC, antibodies, etc?).

(Time?) after the initial evaluation, the patient had an NMO exacerbation and was admitted to the hospital for (IV/PO?) steroid treatment. The patient recovered, nevertheless, had another exacerbation (number) months after. A decision was made to switch her maintanance treatment from Rituximab to Soliris due to inadequate response. She was started with an increasing dose of at 900 mg four times every other week. After the fourth dose, she complained of developing non-pruritic rash in all four extremities, sparing the torso, with an onset duration of (number of weeks from the patient starting the drug to the appearance of the DLE lesions). At cutaneous examination it was possible to observe well-defined, varying sized, coin-shaped erythematous papules and scaly patches on all four extremities(Figure 1A-D). Hair, nails, and skin neighboring mucous membranes were unaffected. Soliris was discontinued and topical steroids were given. After one week evaluation via telemedicine, clinical worsening was observed; lesions continued to increase in number and location during the following week.

She was seen by dermatology service, which after correlating the history, clinical presentation, and laboratory studies concluded it was an exacerbation of discoid lupus erythematosus. No skin biopsy was performed. Laboratory evaluation revealed (positive/negative?) antinuclear antibody, (positive/negative?) anti-double-stranded deoxyribonucleic acid antibody, and (positive/negative?) anti-histone antibodies. Additional studies revealed (normal/high/low) parameters within complete blood cell count, serum chemistries, C-reactive protein, erythrocyte sedimentation rate, anti-Ro/Sjogren’s syndrome A (anti-Ro/SSA) antibody, anti-La/Sjogren’s syndrome B (anti-La/SSB) antibody, anti-ribonuclear protein (RNP) antibody, serum complements (C3 and C4), and urinalysis. She was started with prednisone 50 mg four times per day for four days. After (number) weeks, a clinical improvement in her lesions was observed, with a resolution duration of (number of weeks from the patient stopping the drug to the complete clearing of the DLE lesions).

Discusion

It cannot be said with absolute certainty that eculizumab caused this patient’s cutaneous complication, as we felt it was unsafe to perform a rechallenge test. However, it seems very likely that the eculizumab was an important contributing factor. The rash developed (number of weeks/days) after the first exposure to eculizumab and her DLE was under control by the time she was first seen.

More than 80% of DLE lesions appear as well-defined, erythematous, coin-shaped, with varied size, while less than 20% may be generalized lesions.[10].

The pathophisiology of drug-induced lupus erythematosus (DILE) itself remains to be unknown.[11]. Most cases are associated to chronic exposure of certain drugs such as hydralazine, procainamide, quinidine, isoniazid, minocycline, and targeted immunotherapy.[12][13][14][15] Very few cases of cutaneous DILE have been reported (less than 30), almost exclusively associated with 5-fluorouracil agents.[16] Among them, subacute cutaneous DILE has been mostly reported.[17] 95% of the cases resolve within 2 months after cessation of the culprit medication.[18] In terms of the physiopathology of cutaneous DILE, is also to be established. It has been accepted that the abnormal expresssion of inflammatory cells and an abundant production of pathogenic autoantibodies to a broad range of autoantigens are necessary in the development of DLE. This altered stimulus ultimately cause the deposition of immune complexes in the tissues with stimulatory effects on B cells.[19][20][21][22] To date, more than 180 autoantibodies have been found in the serum of SLE affected patients. Interestingly, high titers of serum ANA and anti-Ro antibodies are found in SLE, unlike in DLE; this may be a key characteristic to distinguish SLE from DLE.[10][23][24] Moreover, the vast majority of DILE have the presence of antihistone antibodies.[25] According to a study evaluating the immunogenicity of Soliris using an electro-chemiluminescence (ECL) bridging assay, only 2% of the 96 Soliris-treated patients with NMOSD developed antibodies against Soliris.[26][27] While, there is a small number of reports of autoimmune reactions with the use of IgG2/IgG4 monoclonal antibody, this mechanism does not explain the antigenic immune response by itself. Interestingly, lupus cutaneous lesions are mostly found in sun exposed areas. Research has found that the immune response targeting to dsDNA frequently starts from the reaction of ribonucleoproteins which are released from the nucleus by UV irradiation, inducing tissue damage by the formation of complexes who detect these as antigens.[28][29][30] Among the three types of UV radiation (A,B, and C), only UVB and UVA have been implicated in the formation of skin lesions.[31]


It is fair to say that the knowledge of the pathogenesis of drug-induced discoid lupus erythematosus and LES in general, is incomplete, and further research is needed to better understand the pathophysiology behind this phenomenon. The evidence base documenting autoimmune reactions with the use of IgG2/IgG4 monoclonal antibody therapy is exceedingly small. To our knowledge, this is the first case reported of reactivation of quiescent discoid lupus erythematosus (DLE) due to Eculizumab in the setting of NMOSD.


It may be usefull a longer followup, including new labs and the final treatment. I found the prior administration of IV dexamethasone before other drug induced DLE, such as with 5FU, had good results clinically and laboratorily. Most case-reports confirm it with a biopsy showing a vacuolar interface dermatitis characterized by atrophic epidermis with follicular plugging, and a perivascular and periadnexal chronic inflammatory infiltrate. drug–drug interaction
