Long-Term Benefits of Tear Exchangeable Limbal-Rigid Contact Lens Wear Therapy in Stevens-Johnson Syndrome Cases.

OBJECTIVES: To evaluate the long-term benefits of tear-exchangeable, limbal-rigid contact lens (CL) wear therapy in patients with Stevens-Johnson syndrome (SJS)-associated ocular sequelae. METHODS: This retrospective study evaluated 50 eyes of 41 SJS patients (15 men and 26 women) who underwent limbal-rigid CL wear therapy for more than 2 years post fitting. Ocular sequelae (i.e., conjunctival hyperemia, corneal neovascularization, and upper tarsus scarring) before fitting and at 3 months, 6 months, 12 months, and annually after initiating CL wear therapy were evaluated and then graded on a severity score (range: 0-3, maximum score: 3). Moreover, visual acuity (VA) at immediately post initiating CL wear therapy was evaluated. RESULTS: The mean follow-up period was 4.3±1.1 years. Compared with before fitting, the mean conjunctival hyperemia score improved from 1.14 to 0.86 at 3 months of CL wear therapy ( P <0.01) and was maintained thereafter; the mean corneal neovascularization score improved from 2.10 to 1.98 at 3 months of CL wear therapy, with no deterioration of the score observed in all cases at the final follow-up examination, and mean VA (log of minimum angle of resolution) improved from 1.60 to 1.04 at immediately post initiating CL wear therapy ( P <0.01). CONCLUSIONS: Limbal-rigid CL wear therapy can provide long-term ocular surface stabilization and improved VA in SJS patients.

[Recalcitrant cicatrizing conjunctivitis. Treatment of nine patients with rituximab]. / Conjuntivitis cicatrizal recalcitrante. Tratamiento de nueve pacientes con rituximab.

Cicatrizing conjunctivitis is the final consequence of several diseases. The most severe among them are cicatricial pemphigoid and chronic Stevens-Johnson syndrome. Systemic immunosuppressive drugs and steroids are usually an effective approach to these diseases. However, a few patients follow a recalcitrant course unremitting to usual therapy. We describe the treatment with rituximab of seven patients with cicatricial pemphigoid and two with chronic Stevens-Johnson syndrome. Eight of them also received gammaglobulin and all achieved clinical remission. Three relapsed and required two or three new courses of rituximab with good control of disease activity. Rituximab proved to be an efficacious drug for chronic recalcitrant cicatrizing conjunctivitis.

La conjuntivitis cicatrizal es la consecuencia de distintas enfermedades oculares. Entre ellas, las más graves son el penfigoide cicatrizal y el síndrome de Stevens-Johnson crónico. El tratamiento de estas enfermedades con corticoides e inmunosupresores es habitualmente exitoso, pero unos pocos pacientes siguen un curso recalcitrante. En los últimos años se introdujo el uso de rituximab, asociado o no a gammaglobulina endovenosa, en forma abierta, para el control de la inflamación conjuntival. Describimos aquí el tratamiento de siete pacientes con penfigoide y dos con Stevens-Johnson recalcitrante, con rituximab. Ocho recibieron también gammaglobulina y todos alcanzaron la remisión de la actividad. Tres recayeron y recibieron dos o tres nuevos cursos de la medicación con mejoría sintomática. El rituximab probó ser una droga efectiva para el tratamiento de la conjuntivitis cicatrizal crónica recalcitrante.

Toxic epidermal necrolysis: the red eye and red herrings in casualty.

A 38-year-old woman presented to casualty with bilateral red eyes associated with a recent upper respiratory tract infection. This was initially diagnosed as conjunctivitis, however systemic review revealed an erythematous facial and skin rash, mildly swollen lips and mild swallowing difficulties. The patient was referred for an urgent medical assessment, by which time she was found to have erythema affecting 54% of her body surface area and diagnosed with suspected toxic epidermal necrolysis (TEN). She rapidly deteriorated over 24 hours with a spreading blistering skin rash and airway compromise requiring urgent intubation and admission to the intensive treatment unit (ITU). Subsequent skin biopsies confirmed the diagnosis of TEN, attributed to recent use of ibuprofen. Treatment included broad-spectrum antibiotics and high-dose corticosteroids. The patient had a prolonged hospital stay and developed severe scarring of the ocular surface. She was discharged home and remains under continuing outpatient follow-up with ophthalmology and dermatology teams.

Microbial keratitis in Stevens-Johnson syndrome: Clinical and microbiological profile.

PURPOSE: To study the clinical and microbiological profile of microbial keratitis in Stevens-Johnson syndrome (SJS). STUDY DESIGN: Case series. PARTICIPANTS: Patients with SJS who developed microbial keratitis. METHODS: Medical records and microbiological data of patients with SJS who developed microbial keratitis from January 1991 to December 2012 were reviewed. We analysed the type of causative organisms and their antibiotic susceptibility along with the clinical pattern and responses to medications in this group of patients. MAIN OUTCOME MEASURE: Clinical and microbiological profile of microbial keratitis. RESULTS: We reviewed 65 eyes of 60 patients seen between January 1991 and December 2012. Positive microbiological culture results were obtained in 45 eyes (69.2%). Isolated bacterial infections were noted in 27 eyes (60%) while isolated fungal growth was seen in 1/45 eyes (2.2%). Polymicrobial infections were noted in 17/45 eyes (37.8%). The most common bacteria isolated were Staphylococcus species (35%). The median duration of SJS before presentation was 5 months (IQR, 2 months to 7 years) with 50% presenting within four months of the onset of SJS. Twenty-eight eyes (43%) needed treatment in addition to antibiotics for resolution of tarsorraphy, epilation, tissue adhesive application, and amniotic membrane grafting or punctal cautery. The average time for resolution was 25 days. CONCLUSION: Microbial keratitis in SJS patients is different from patients without SJS in presentation and the response to medications. It requires a multi-disciplinary approach for healing.

Necrolisis epidérmica tóxica: un paradigma de enfermedad crítica / Toxic epidermal necrolysis: a paradigm of critical illness

RESUMEN La necrolisis epidérmica tóxica es una reacción cutánea adversa de tipo inmunológico secundaria en la mayor parte de los casos a la administración de un fármaco. La necrolisis epidérmica tóxica, el síndrome de Steven Johnson y el eritema exudativo multiforme forman parte del mismo espectro de enfermedad. La mortalidad de la necrolisis epidérmica tóxica es alrededor del 30%. La fisiopatología de la necrolisis epidérmica tóxica es semejante en muchos aspectos a la de las quemaduras dérmicas superficiales. La afectación mucosa del epitelio ocular y genital se asocia con secuelas graves si no se trata de forma temprana. Se acepta en general que los pacientes con necrolisis epidérmica tóxica son tratados mejor en unidades de grandes quemados, donde existe experiencia en el manejo de enfermos con pérdida cutánea extensa. El tratamiento es de soporte, eliminación y cobertura con derivados biosintéticos de la piel de las zonas afectadas, tratamiento de la afectación mucosa, y tratamiento inmunosupresor específico. De los tratamientos ensayados sólo se usa actualmente en la mayor parte de los centros la inmunoglobulina G y la ciclosporina A, aun cuando no existe evidencia sólida para recomendar ningún tratamiento específico. Entre los aspectos particulares del tratamiento de esta enfermedad se encuentra la prevención de secuelas relacionadas con la formación de sinequias, los cuidados oculares para prevenir secuelas graves que pueden conducir a la ceguera, y el tratamiento específico inmunosupresor. Un mejor conocimiento de los principios del manejo de la necrolisis epidérmica tóxica llevará a un mejor manejo de la enfermedad, a una mayor supervivencia y una menor prevalencia de las secuelas.

ABSTRACT Toxic epidermal necrolysis is an adverse immunological skin reaction secondary in most cases to the administration of a drug. Toxic epidermal necrolysis, Stevens-Johnson syndrome, and multiform exudative erythema are part of the same disease spectrum. The mortality rate from toxic epidermal necrolysis is approximately 30%. The pathophysiology of toxic epidermal necrolysis is similar in many respects to that of superficial skin burns. Mucosal involvement of the ocular and genital epithelium is associated with serious sequelae if the condition is not treated early. It is generally accepted that patients with toxic epidermal necrolysis are better treated in burn units, which are experienced in the management of patients with extensive skin loss. Treatment includes support, elimination, and coverage with biosynthetic derivatives of the skin in affected areas, treatment of mucosal involvement, and specific immunosuppressive treatment. Of the treatments tested, only immunoglobulin G and cyclosporin A are currently used in most centers, even though there is no solid evidence to recommend any specific treatment. The particular aspects of the treatment of this disease include the prevention of sequelae related to the formation of synechiae, eye care to prevent serious sequelae that can lead to blindness, and specific immunosuppressive treatment. Better knowledge of the management principles of toxic epidermal necrolysis will lead to better disease management, higher survival rates, and lower prevalence of sequelae.

Dystrophic calcification and accentuated localized Argyria after fractionated carbon dioxide laser therapy of hypertrophic scars.

IMPORTANCE: Fractionated, ultrapulsed carbon dioxide (CO2) laser therapy is a powerful tool for the treatment of scars. Common adverse effects of this therapeutic modality have been previously documented. We describe 2 unreported adverse effects of ultrapulsed CO2 laser treatment of mature scars in a patient previously treated with silver-impregnated dressings. OBSERVATIONS: A teenage survivor of toxic epidermal necrolysis presented with faint but diffuse dyschromia clinically and histologically consistent with localized argyria secondary to silver-impregnated dressings used years earlier. The patient was subsequently treated with fractionated CO2 for her scarring, but her hyperpigmentation worsened with each treatment. A subsequent biopsy specimen revealed a zone of dystrophic calcification with adjacent pseudo-ochronotic fibers that were not appreciated on biopsy specimens taken before CO2 laser treatment, suggesting unique complications not previously reported. CONCLUSIONS AND RELEVANCE: We present 2 unique complications secondary to ultrapulsed, fractionated CO2 laser treatment in a patient previously treated with silver-impregnated dressings: (1) the appearance of pseudo-ochronotic fibers in areas of worsening pigmentation and (2) evidence of dystrophic calcification limited to columns of fractionated laser ablation. Therefore, a history of argyria or treatment with silver-impregnated dressings should be considered before treatment with fractionated CO2 lasers.

Stevens-Johnson syndrome induced by sorafenib for metastatic renal cell carcinoma.

Sorafenib is an orally administered active multikinase inhibitor for metastatic renal cell carcinoma that is now considered a standard agent. Skin toxicity, such as hand-foot skin reaction, is one of the frequent adverse effects of sorafenib. On the other hand, sorafenib-induced erythema multiforme is very rare, and Stevens-Johnson syndrome and toxic epidermal necrolysis induced by sorafenib have not been reported. We report the first case of Stevens-Johnson syndrome caused by sorafenib for metastatic renal cell carcinoma.

"Triple-TEN" in the treatment of acute ocular complications from toxic epidermal necrolysis.

PURPOSE: Toxic epidermal necrolysis (TEN) is a devastating form of Stevens-Johnson syndrome (SJS) with acute and chronic ocular complications. We present a novel aggressive combination strategy, termed "Triple-TEN", for the management of acute ocular TEN designed to minimize the risk of chronic, blinding sequelae. METHODS: Two patients with life-threatening TEN accompanied by severe ocular surface defects and fulminant symblephara formation underwent "Triple-TEN" management of their acute ocular disease under aseptic techniques in the critical care setting, after failed treatment with intensive topical therapy and surgical division of symblephara. The Triple-TEN protocol comprises (1) subconjunctival triamcinolone (Kenalog 20 mg) administered into each of the fornices to curb the local inflammatory response without compromising systemic immunity, (2) placement of amniotic membrane tissue mounted on a polycarbonate skirt (ProKera) over the corneal and limbal regions to facilitate reepithelialization of the ocular surface, and (3) insertion of a steeply curved acrylic scleral shell spacer (Technovent, SC21) to vault the lids away from the globe providing a barrier to symblephara formation. RESULTS: In both cases, ocular surface inflammation resolved within 4 weeks with no progression of conjunctival cicatrization or evidence of limbal epithelial stem cell failure at 1 year follow-up. There were no long-term complications of the Triple-TEN regimen. CONCLUSIONS: Aggressive treatment with the Triple-TEN protocol for acute ocular TEN resistant to first-line therapy, may help prevent long-term blinding sequelae.

Systemic monoclonal antibody therapy (daclizumab) in the treatment of cicatrizing conjunctivitis in stevens-johnson syndrome, refractory to conventional therapy.

PURPOSE: At least one-year follow-up of a case series of young Stevens-Johnson syndrome (SJS) patients with cicatrizing ocular surface disease and recurrent inflammation (SJS-RI) treated with systemic humanized monoclonal antibody (daclizumab). METHODS: Five patients (median age 16 yr; range 8-34 yr) with SJS, with recurrent inflammation refractory to conventional immunotherapy, were enrolled in a prospective non-randomized case series study. Inclusion criteria were patients with SJS and ocular cicatrizing inflammatory disease with severe visual impairment, using topical or systemic anti-inflammatory and/or immunomodulatory drugs without clinical improvement resulting in persistent inflammation (SJS-RI). Treatment with Daclizumab 1 mg/Kg (intravenous) was scheduled in three cycles. First cycle with concomitant immunotherapy: a total of 5 doses, with 14 days interval between them (total of this cycle: 10 weeks). Second cycle: interval was increased to 3 weeks; the patients received 2 doses (the second cycle had a total of 6 weeks). Third cycle: maintenance phase with 4 weeks interval between each application, until at least 12 months of the total follow up. After the first cycle (5th dose), the patients were kept with preservative-free lubricants and systemic doxycycline. RESULTS: Control of ocular inflammation was observed at a median of 8 weeks (range 6-10 weeks) in all patients, with relapses in two patients at 20-36 weeks. Relapses were controlled with topical steroids at a median of 10 days, and within 2 weeks the steroids were tapered for both patients. CONCLUSION: In this small case series, daclizumab demonstrated to play a beneficial role in the control of the inflammatory process of the recurrent inflammation in SJS, refractory to conventional immunomodulatory therapy.

Piel y ojo / Skin and eye

Piel y ojo comparten un origen común a partir del neuroectodermo (en el ojo, estructurales pricilpalmente esclerocorneanas) (1). La similitud de los epitelios de superficie y de sitios pigmentarios, la contiguidad palpebroconjuntival, la exposición idéntica a microorganismos o alergenos y factores del medio ambiente, los mecanismos de defensa similares, y mecanismos autoinmunes (escleroconjuntiva y úvea), son factores que pueden explicar la patologías comunes, llevando a una sintomatología a la vez dermatológica y oftalmológica; así, enfermedades tales como neurofibromatosis, dermatosis bulosa, vasculitis, Behcet, dermatis atópica y rosácea, son ejemplos de patologías compartidas. El objetivo de esta revisión es definir y explicar cuándo el dermatólogo debe solicitar la evaluación de un oftalmologo

Stevens-Johnson syndrome with associated nasolacrimal duct obstruction treated with dacryocystorhinostomy and Crawford silicone tube insertion.

Although Stevens-Johnson syndrome (SJS) has long been recognized as a cause of punctal and canalicular obstruction, nasolacrimal duct obstruction secondary to SJS is rare and has not been reported in the ophthalmologic literature. Keratoconjunctivitis sicca, entropion, and trichiasis are well-known complications of SJS that may require measures to supplement or preserve tears. Lacrimal drainage system obstruction may occasionally occur in the face of relatively normal tearing, resulting in clinically significant epiphora. We report two cases of SJS, one associated with epidemic keratoconjunctivitis, that led to nasolacrimal duct obstruction and canalicular obstruction or stenosis. Epiphora and, in one case, dacryocystitis, necessitated dacryocystorhinostomy and Crawford tube insertion.
