Thalidomide is the drug of choice for erythema nodosum leprosum (ENL) in men. Its use in patients with multiple myeloma has been reported to cause venous thrombosis. Postulated mechanism is an increase in procoagulant state with the use of thalidomide along with corticosteroids in the underlying hyperviscosity in multiple myeloma. We report a case of superficial and deep vein thrombosis and chronic pulmonary vein embolism in a patient of ENL treated with thalidomide and corticosteroid. An increase in procoagulant state with the use of these two medicines along with a persistent inflammatory state in ENL and an increased risk of venous thrombosis in type 3 hypersensitivity together may have resulted in thrombus formation.

Thalidomide and corticosteroid use in a patient of erythema nodosum leprosum (ENL) may cause both superficial vein thrombosis and deep vein thrombosis (DVT).
| Case Description|| |
A 45-year-old male presented with chief complaints of pain and swelling in the left calf region for the past 45 days, gradually progressive dyspnea on exertion for the past 1 month with increased severity and dyspnea at rest for the past 6–7 days. He had been previously diagnosed with lepromatous leprosy (LL), and treatment with multibaccilarry (MB) regimen (rifampicin 600 mg once monthly, clofazine both daily [50 mg] and monthly [300 g] dose, and dapsone 100 mg daily) for the same was started 1 year back; however, after few months of therapy, he developed ENL. He was prescribed thalidomide 100 mg twice daily and prednisolone with plan to taper medications according to the response of treatment. The patient did not return for follow-up and had been self-medicating with thalidomide and prednisolone in varying doses for the past 9 months. No treatment records were available. The patient did not have any other significant history and denied consumption of tobacco, alcohol, or any other substance. On admission to the emergency, his blood pressure was 100/60 mmHg, pulse rate was 118/min regular, respiratory rate was 26/min at rest. Jugular pressure (JVP) was elevated. CVS examination revealed a systolic murmur in tricuspid area suggestive of tricuspid regurgitation (TR). There was tender hepatomegaly and bilateral pitting type ankle edema. There was marked swelling of the left leg up to mid-thigh with tenderness of calf. His hematological and biochemical profile was unremarkable. Autoimmune markers including antinuclear antibody (ANA) and antiphospholipid antibody (APS) were negative. Since the findings were suggestive of DVT with a suspicion of right heart failure, further investigations were planned. A 2D echo showed grossly dilated Right Atria and Right Ventricle with severe TR and a calculated pulmonary artery pressure of 57 mmHg [Figure 1]. Color Doppler of the left lower limb was also done. There were dilation and intraluminal thickening without color uptake in great saphenous, left distal superficial femoral, popliteal, short sephanous, posterior tibial, and anterior tibial veins, which was suggestive of multiple venous thrombosis (chronic superficial vein thrombosis and DVT). Computed tomography pulmonary angiography was done which showed filling defects in both right and left main pulmonary arterial branch and segmental branches of both lungs, upper and lower lobe and right middle lobe with dilated pulmonary trunk (32 mm) [Figure 2].

He was diagnosed as chronic pulmonary thromboembolism (CPTE) with multiple venous thrombosis (superficial vein thrombosis and DVT). He was started on rivoroxaban (15 mg BD) and diuretics and his symptoms started to resolve gradually in the next few days and switched to rivoroxaban 20 mg daily single dose with diuretics. On close follow-up of 1–2 months duration, his symptoms subsided and have only mild breathlessness on performing exertion work.
| Discussion|| |
DVT is not an uncommon condition with a risk of thrombosis in age below 55 of less than 2% and more than 5% in age more than 65. Factors predisposing to thrombosis are procoagulant mutation, atherosclerosis, diabetes, hypertension, obesity, active cancer, smoking, immobility, major surgery within 3-month period. Chronic systemic inflammation can also predispose to venous thrombosis. Persistent inflammatory state is associated with decreased antithrombin 3, protein c, which are naturally occurring anticoagulants and endothelial dysfunction, which predispose to prothrombotic stage in many conditions such as Becet disease, Rhematoid Arthritis, ANCA (Anti Nuclear Cytoplasmic Antibodies) vasculitis, and APLA (Antiphospholipid antibodies) syndrome.
ENL is an immune-mediated inflammatory complication affecting mainly LL and borderline leprosy (BL). It can present anytime during, before, or after the therapy. It is a clinical diagnosis in a patient of LL/BL. It is considered a type 3 hypersensitivity response and affects multiple organs causing systemic illness. Type 3 hypersensitivity reaction predisposes to venous thrombosis. This has also been identified in the COVID-19 epidemic, where COVID infection leads to a type 3 hypersensitivity. In COVID-19 infection, an increase in the procoagulant activity has been reported., Symptomatic venous theomboembolism (VTE) is seen in up to 25% patients in the intensive care units and anticoagulation with heparin is the recommended modality of treatment.
In a patient of ENL, a type 3 hypersensitivity reaction, the risk of venous thrombosis, is further increased by the use of thalidomide and corticosteroid. Thalidomide is a synthetic glutamic acid derivative; it is also known to inhibit interleukin-6 (IL-6) production and tumor necrosis factor (TNF)-induced nuclear factor-κB activation in Jurkat cells. TNF alpha is known to enhance neoangiogeneis by itself and/or by interaction with IL-6 which is known to be involved in pathogenesis of multiple myeloma; for this property, it is widely used in patients of multiple myeloma.,,, It is highly teratogenic and is absolutely contraindicated in pregnancy/reproductive age group female. Common adverse effects include sedation, constipation, and sensorimotor polyneuropathy. The most serious and life-threatening adverse effect of thalidomide is VTE. The risk of thrombosis increases significantly; if used together with corticosteroid, the risk is nearly 2%–3% alone and 8% if used along with corticosteroid.
The risk of venous thrombosis with thalidomide in multiple myeloma and other cancer is well known, and there are also multiple case reports to this; multiple myeloma in itself is a hypercoagulable state may be another predisposing factor for thrombosis. However, there are only few case reports in the last decades where a patient of ENL taking thalidomide and corticosteroid develops venous thrombosis.
Here, we report a case of a patient with ENL treated with thalidomide and corticosteroid for long time (9 months), with poor follow-up who develops CPTE with DVT and superficial venous thrombosis, who did not had any previous risk factor venous thrombosis.
We can hypothesize that thalidomide and corticosteroid use together may have produced a prothrombotic state in ENL patient where early stages of thrombus have flourished in preexisting persistent systemic inflammatory state of ENL.
Those patients of ENL who are taking thalidomide with corticosteroid together should be monitored regularly for signs and symptoms of DVT and pulmonary embolism .
