RESUMEN
Löfgren syndrome (LS) is a unique acute manifestation of sarcoidosis and characterized by erythema nodosum, bilateral hilar lymphadenectasis, and/or bilateral ankle arthritis or periarthritis. A 37 - year - old female patient with LS presented with fever accompanied by multiple joint swelling and pain, nodular skin erythema, and bilateral hilar lymphadenectasis. The patient had received treatment involving non - steroidal anti - inflammatory drugs and glucocorticoids in other hospitals, but the effects were poor, and the conditions reemerged. The LS duration has lasted for more than 3 months. Following traditional Chinese medicine (TCM) treatment, syndrome differentiation as well as giving patients oral Chinese medicine decoction, the symptoms of the patient were rapidly relieved within one week and did not recur during a six - month follow - up period. This case is the first clinical report of acute sarcoidosis LS treated using T CM and reflects the significant advantages of this form of therapy in emergency treatment
El síndrome de Löfgren (LS) es una manifest ación única y aguda de sarcoidosis, caracterizada por eritrema nodoso, linfadenectasis hilar bilateral, y/o a r tritis de tobillo bilateral o periartritis. Una paciente de 37 años de sexo femenino con LS se presentó con fiebre, acompañada de inflamación y do lor múltiple de articulaciones, eritrema nodular cutáneo, y linfadenectasis hilar bilateral. La paciente recibió un tratamiento que consistió en antiinflamatorios no esteroidales y glucocorticoides en otros hospitales, pero los efectos fueron leves y las c ondiciones reemergieron. El LS ha durado más de tres meses. Siguiendo el tratamiento de medicina tradicional china (MTC), la diferenciación de síndrome, así como darles a los pacientes una decocción de medicina china por vía oral, los síntomas de la pacien te rápidamente fueron aliviados en el curso de una semana y no recidivaron durante los seis meses de un seguimiento. El caso es el primer reporte clínico de tratamiento de sarcoidosis aguda asociada a LS usando TCM y refleja las significativas ventajas de esta forma de terapia en el tratamiento de emergencia.

BACKGROUND: Erythema nodosum leprosum (ENL) is an acute and systemic inflammatory reaction of leprosy characterised by painful nodules and involvement of various organs. Thalidomide is an immunomodulatory and anti-inflammatory drug currently used to treat this condition. Cereblon (CRBN) protein is the primary target of thalidomide, and it has been pointed out as necessary for the efficacy of this drug in others therapeutics settings. OBJECTIVES: In this study, we aimed to evaluate the influence of CRBN gene variants on the dose of thalidomide as well as its adverse effects during treatment of ENL. METHODS: A total of 103 ENL patients in treatment with thalidomide were included in this study. DNA samples were obtained from saliva and molecular analysis of CRBN gene were performed to investigate the variants rs1620675, rs1672770 and rs4183. Different genotypes of CRBN variants were evaluated in relation to their influence on the dose of thalidomide and on the occurrence of adverse effects. FINDINGS: No association was found between CRBN variants and thalidomide dose variation. However, the genotypes of rs1672770 showed association with gastrointestinal effects (p = 0.040). Moreover, the haplotype DEL/C/T (rs4183/rs1672770/rs1620675) was also associated with gastrointestinal adverse effects (p = 0.015). MAIN CONCLUSIONS: Our results show that CRBN variants affect the treatment of ENH with thalidomide, especially on the adverse effects related to the drug.

Abstract Erythema nodosum leprosum is a severe immune reaction that complicates the usual course of multibacillary leprosy. There is increased activation of T-cells in erythema nodosum leprosum. Treatment modalities available to date for the management are systemic steroids, thalidomide, methotrexate, cyclophosphamide, azathioprine, minocycline, and apremilast but none of them is promising and safe. Mycobacterium indicus pranii is an atypical mycobacterium possessing strong immunomodulatory properties. The vaccine for this mycobacterium has been shown to have both immunotherapeutic and immunoprophylactic effects in multibacillary leprosy patients. We report a case of chronic recalcitrant erythema nodosum Leprosum which responded to Mycobacterium indicus pranii vaccine without any adverse effects, thereby suggesting its role as a novel therapeutic option in this reaction.

INTRODUCTION: Thalidomide is an immunomodulatory drug and first choice in the treatment of erythema nodosum leprosum. Given its teratogenic potential, it is essential that an effective contraceptive method is used, especially a long-acting reversible contraceptive (LARC) method. The subdermal etonogestrel (ENG)-releasing implant is an adequate method due to the high effectiveness and long-term use. However, interaction between thalidomide and ENG has not been well documented. Concern arises because thalidomide interacts with cytochrome P450 (CYP450) enzymes that metabolize sexual steroids. AIM: We aimed to study the effectiveness and safety of the ENG-implant in a thalidomide user. METHODS: Case report of a sexually active 21-year-old patient with both Hansen's disease and leprosy reaction type 2 treated with thalidomide requiring effective contraception. Follow-up was up to 36 months after implant placement. RESULTS: Contraception with ENG-implant was effective and safe, based on clinical parameters (reduction of menstrual flow and cervical mucus thickening) and laboratory parameters (gonadotropins and sexual steroids). CONCLUSION: To the best of our knowledge, this is the first case reported which presents a patient in simultaneous use of thalidomide and ENG-implant. Although this case report preliminary supports effectiveness and safety of ENG-implant as a contraceptive option in women using thalidomide, rigorous drug-drug interaction research is needed to better characterize the interaction between thalidomide and the ENG-implant.

INTRODUCTION: One of the biggest drug disasters in history has not prevented thalidomide from being used to treat various clinical conditions. Currently, Brazil has a worrying scenario: high consumption of the drug and, cases of pregnant women using thalidomide, even after adopting restrictive legislation. AREAS COVERED: This review of the literature and legislation sought to comparatively analyze the monitoring of thalidomide use in Brazil and other countries that use this drug. Finally, we discuss the differences between the countries. EXPERT OPINION: This analysis allows us to think beyond the safe use of thalidomide, but the safety provided by any type of monitoring system. It seems that out-patients that use unsafe drugs are exposed to some degree of risk. To improve safety, more extensive improvements are needed than monitoring systems related to the use of thalidomide. Its safe use depends on a drastic reduction in the incidence of leprosy and Erythema Nodosum Leprosum in the world; investment in research and development of safe and effective therapeutic alternatives to thalidomide; improvement of health systems and their health surveillance systems, particularly in primary health care; awareness of health professionals and patients for greater responsibility in the use of medicines, especially thalidomide.

Resumen La lepra o enfermedad de Hansen es una de las clásicas enfermedades olvidadas que aún persiste en Perú. La infección es ocasionada por Mycobacterium leprae. La enfermedad varía en un amplio rango de manifestaciones desde la lepra tuberculoide (paucibacilar) hasta la lepromatosa (multibacilar). Se presenta el caso de un varón de 55 años, agricultor y extractor de madera, procedente de la Amazonia peruana, con lesiones cutáneas antiguas infiltrantes en la cara, cuello, tórax, abdomen y extremidades. La baciloscopia y estudio histológico de una biopsia de piel confirmaron la presencia de bacilos ácido-alcohol resistentes. Se concluyó, en forma tardía, que fue un caso de lepra lepromatosa nodular. Recibió terapia con rifampicina, dapsona y clofamizina por dos años con una lenta mejoría; no obstante, cursó con un eritema nodoso leproso (reacción tipo 2) con buena respuesta a corticoesteroides y talidomida.
Abstract Leprosy or Hansen's disease is one of the classic neglected diseases that still persists in Peru. The infection is caused by Mycobacterium leprae. The disease varies in a wide range of manifestations from tuberculoid (paucibacillary) to lepromatous (multibacillary) leprosy. We present the case of a 55-year-old man, farmer and wood extractor, from the Peruvian Amazon with old infiltrating cutaneous lesions on the face, neck, thorax, abdomen and extremities. The smear and biopsy examinations confirm the presence of acid-alcohol-resistant bacilli compatible with leprosy. It is concluded, with a long delay, it was a case of nodular lepromatous leprosy. He received therapy with rifampicin, dapsone and clofamizine for two years with slow progressive improvement; however, he presented an erythema nodosum leprosum (type 2 reaction) with response to corticosteroids and thalidomide.

Erythema nodosum is the most common form of panniculitis and is characterized by tender erythematous nodules mainly in the lower limbs on the pretibial area. The exact cause of erythema nodosum is unknown, although it appears to be a hypersensitivity response to a variety of antigenic stimuli. Although the etiology is mostly idiopathic, ruling out an underlying disease is imperative before diagnosing primary erythema nodosum. Erythema nodosum can be the first sign of a systemic disease that is triggered by a large group of processes, such as infections, inflammatory diseases, neoplasia, and/or drugs. The most common identifiable causes are streptococcal infections, primary tuberculosis, sarcoidosis, Behçet disease, inflammatory bowel disease, drugs, and pregnancy. We propose a diagnostic algorithm to optimize the initial work-up, hence initiating prompt and accurate management of the underlying disease. The algorithm includes an initial assessment of core symptoms, diagnostic work-up, differential diagnosis, and recommended therapies. Several treatment options for the erythema nodosum lesions have been previously reported; nevertheless, these options treat the symptoms, but not the triggering cause. Making an accurate diagnosis will allow the physician to treat the underlying cause and determine an optimal therapeutic strategy.

INTRODUCTION: Erythema nodosum leprosum (ENL) is an immunological complication of leprosy. ENL results in morbidity and disability and if it is not treated can lead to death. The current treatment consists of thalidomide or high doses of oral corticosteroids for prolonged periods. Thalidomide is not available in many leprosy endemic countries. The use of corticosteroids is associated with morbidity and mortality. Identifying treatment regimens that reduce the use of corticosteroids in ENL is essential. Methotrexate (MTX) is used to treat many inflammatory diseases and has been used successfully to treat patients with ENL not controlled by other drugs, including prednisolone and thalidomide. We present the protocol of the 'MTX and prednisolone study in ENL' (MaPs in ENL) a randomised controlled trial (RCT) designed to test the efficacy of MTX in the management of ENL. METHODS AND ANALYSIS: MaPs in ENL is an international multicentre RCT, which will be conducted in leprosy referral centres in Bangladesh, Brazil, Ethiopia, India, Indonesia and Nepal. Patients diagnosed with ENL who consent to participate will be randomly allocated to receive 48 weeks of weekly oral MTX plus 20 weeks of prednisolone or 48 weeks of placebo plus 20 weeks of prednisolone. Participants will be stratified by type of ENL into those with acute ENL and those with chronic and recurrent ENL. The primary objective is to determine whether MTX reduces the requirement for additional prednisolone. Patients' reported outcome measures will be used to assess the efficacy of MTX. Participants will be closely monitored for adverse events. ETHICS AND DISSEMINATION: Results will be submitted for publication in peer-reviewed journals. Ethical approval was obtained from the Observational/Interventions Research Ethics Committee of the London School of Hygiene & Tropical Medicine (15762); The Leprosy Mission International Bangladesh Institutional Research Board (in process); AHRI-ALERT Ethical Review Committee, Ethiopia; Ethics Committee of the Managing Committee of the Bombay Leprosy Project; and The Leprosy Mission Trust India Ethics Committee; the Nepal Health and Research Council and Health Research Ethics Committee Dr. Soetomo, Indonesia. This study is registered at www.clinicaltrials.gov. This is the first RCT of MTX for ENL and will contribute to the evidence for the management of ENL.Trial registration numberNCT 03775460.

We report a case of visceral leishmaniasis (VL)/HIV coinfection in a patient undergoing regular antiretroviral therapy and treatment with thalidomide for erythema nodosum leprosum. He presented at a health service with high fever, chills, asthenia, pale skin, lower limb edema, hepatomegaly, and splenomegaly. Visceral leishmaniasis was confirmed by direct examination, and serological and molecular tests. Serum levels of Th1/Th2 cytokines were measured. The patient began treatment with liposomal amphotericin B, with good clinical response; however, VL recurred 6 months later. Treatment was reinitiated, maintaining secondary prophylaxis with liposomal amphotericin B. The patient showed clinical improvement with important recovery of CD4+ T-lymphocyte count.

The drug thalidomide has resurged in the world market under restrictive conditions for marketing and use. In Brazil, there are still cases of pregnant women using thalidomide even after the implementation of laws that regulate the control of use (Law No. 10.651/2003 and Collegiate Board Resolution No. 11/2011). The objective of this study was to discuss the control of thalidomide use in Brazil, based on a scoping review of the scientific literature, documents, and data from the Ministry of Health. A total of 51 studies and documents related to the following subthemes were selected: (1) organization of access and use of thalidomide in the health system; (2) epidemiological and population characteristics of people affected by leprosy; and (3) occurrence of pregnancy and cases of embryopathy with the use of thalidomide. The results showed that Brazil has no unified information database about thalidomide patients. Furthermore, there is inconsistency in the accreditation of public health centers that dispense this medicine, in a country that has a high consumption of thalidomide in the Unified Health System. A large part of this amount of dispensed medicine is intended for the treatment of erythema nodosum leprosum, mainly in the North, Northeast, and Central-West regions of the country, which are endemic for leprosy. This disease is the only one among the clinical indications of the medicine approved in Brazil that does not have a Clinical Protocol and Therapeutic Guidelines. The control of thalidomide use in Brazil presents historical regulatory failures. These are currently linked to the organization and structure of primary healthcare in the country, as well as to the lack of leadership of the Ministry of Health and National Health Surveillance Agency when it comes to managing the process of control of this use.

Erythema nodosum leprosum (ENL) is an inflammatory complication in leprosy. Yet, the involvement of ENL neutrophils in the inflammatory response against Mycobacterium leprae remains poorly explored. Our primary aim was to investigate the utility of the surface expression of neutrophil IL-10R1 as an ENL biomarker and, secondarily, to evaluate whether leprosy or healthy M. leprae-stimulated neutrophils produce cytokines and are able to respond to IL-10. We, in this study, describe a subpopulation of circulating neutrophils of ENL patients that exclusively expressed IL-10R1, providing evidence that IL-10R1+ neutrophils are present in ENL lesions. It was also found that ENL neutrophils, but not those of nonreactional leprosy controls, were able to secret detectable levels of TNF ex vivo and the addition of IL-10 blocked TNF release. It was likewise observed that M. leprae-stimulated, healthy neutrophils expressed IL-10R1 in vitro, and ENL-linked cytokines were released by M. leprae-cultured neutrophils in vitro. Moreover, consistent with the presence of a fully functional IL-10R, the addition of IL-10 prevented the release of M. leprae-induced cytokines. Most importantly, dead M. leprae revealed its superior capacity to induce CCL4 and IL-8 in primary neutrophils over live Mycobacterium, suggesting that M. leprae may hamper the inflammatory machinery as an immune escape mechanism.

Aim: To evaluate the effects of gene polymorphisms in the treatment of erythema nodosum leprosum with prednisone/thalidomide. Patients & methods: A total of 152 patients from different regions of Brazil were included. Generalized estimating equation was used to evaluate the influence of polymorphisms and haplotypes on the drug dose variation throughout the treatment. Results: An association between the genotype tuberculoid of polymorphism ABCB1 3435C>T (rs1045642; p = 0.02) and prednisone dose was found in the recessive model. An association between the haplotypes 1031T/-863C/-857C/-308A/-238G (p = 0.006) and 1031T/-863C/-857T/-308A/-238G (p = 0.040) of the TNF gene and the CYP2C19*2 polymorphism were also identified, in relation to thalidomide dosage variation over the course of treatment. Conclusion: This work presents the first pharmacogenetic report of association between gene polymorphisms and erythema nodosum leprosum treatment with prednisone/thalidomide.

BACKGROUND: Erythema nodosum leprosum may appear before, during or after treatment of leprosy and is one of the main factors for nerve damage in patients. When it occurs or continues to occur after treatment, it may indicate disease recurrence and a new treatment may be instituted again. OBJECTIVE: To evaluate the retreatment of patients with multibacillary leprosy who underwent standard treatment with multidrug therapy, but developed or continued to present reactions of erythema nodosum leprosum and/or neuritis 3-5 years after its end. METHOD: For this objective, a new treatment was performed in 29 patients with multibacillary leprosy who maintained episodes of erythema nodosum and/or neuritis 3-5 years after conventional treatment. RESULTS: In general, we observed that 27 (93.10%) had no more new episodes after a follow up period of eight months to five years. In five of these patients the reason for the retreatment was the occurrence of difficult-to-control neuritis, and that has ceased to occur in all of them. STUDY LIMITATIONS: Small number of patients.. CONCLUSION: In the cases observed, retreatment was an effective measure to prevent the occurrence of erythema nodosum leprosum and/or persistent neuritis.

Erythema Nodosum Leprosum (ENL) occurs due to the immunological complication of multibacillary leprosy and is characterized by painful nodules and systemic compromising. It is usually recurrent and/or chronic and has both physical and economic impact on the patient, being a very important cause of disability. In addition, ENL is a major health problem in countries where leprosy is endemic. Therefore, adequate control of this condition is important. The management of ENL aims to control acute inflammation and neuritis and prevent the onset of new episodes. However, all currently available treatment modalities have one or two drawbacks and are not effective for all patients. Corticosteroid is the anti-inflammatory of choice in ENL but may cause dependence, especially for chronic patients. Thalidomide has a rapid action but its use is limited due the teratogenicity and neurotoxicity. Clofazimine and pentoxifylline have slow action and have important adverse effects. Finally, there is no pattern or guidelines for treating these patients, becoming more difficult to evaluate and to control this condition. This review aims to show the main drugs used in the treatment of ENL and the challenges in the management of the reaction.

One of the biggest challenges in treating leprosy is the control of reaction events. Patients with lepromatous leprosy may present reaction type II, or erythema nodosum leprosum, during treatment, and this reaction can remain in a recurrent form after being released from the hospital, requiring the use of thalidomide and/or prednisone for long periods of time, in turn increasing the risk of side effects. Two reports of the use of antiTNF to treat erythema nodosum leprosum were found in the literature. A good response was found after an assay with infliximab and etanercept. This study reports on a patient with lepromatous leprosy and recurrent reaction, controlled by using etanercept and a 10-month follow-up, with the interruption of thalidomide and the maintenance of prednisone at 10 mg/day.
