Real-world incidences and risk factors of immune-related adverse events in patients treated with immune checkpoint inhibitors: A nationwide retrospective cohort study.

Immune-related adverse events (irAEs) caused by immune checkpoint inhibitors (ICIs) are rare but fatal, requiring systemic steroid use. Therefore, to examine the outcomes, incidence, timing, and risk factors of ICI-associated steroid-requiring severe irAEs, we conducted a nationwide, retrospective, cohort study utilizing the Korean Health Insurance and Review Assessment database. We identified 357,010 patients with lung cancer, bladder cancer, or skin melanoma, eligible for ICI reimbursement in Korea between January 2012 to June 2020. Steroid-requiring severe irAEs following ICI treatment or treatment-emergent AEs following cytotoxic chemotherapy were defined as moderate- or high-dose steroid administration for over 2 consecutive days, along with corresponding ICD-10 codes indicating affected organ systems. The ICI-exposed group (N = 10,118) was compared to a matched cohort of 55,436 ICI-unexposed patients treated with cytotoxic chemotherapy. Incidences of acute severe irAEs requiring moderate- and high-dose steroids were higher in the ICI-exposed group (1.95% and 6.42%, respectively). The ICI-exposed group also had a higher risk of developing delayed severe irAEs requiring moderate- and high-dose steroid use (3.89% and 7.39%). Male sex, high comorbidity index, or previously diagnosed autoimmune diseases were associated with an increased risk of severe irAEs. Notably, 27.4-38.8% of the patients experienced recurrent severe irAEs after re-challenge with ICIs following moderate- or high-dose steroid use, with the severity matching the initial episode. Steroid-requiring severe irAEs were significantly more prevalent among patients exposed to ICIs than among those treated with chemotherapy in acute and delayed periods.

Comparison of greater occipital nerve blockade with radiofrequency and steroid in chronic migraine.

OBJECTIVES: The study aims to retrospectively compare steroid and radiofrequency treatments for the greater occipital nerve(GON) under ultrasound guidance in chronic migraine. METHODS: Monthly average headache attack frequency, attack duration, visual analog scale(VAS) and the number of days analgesics were taken were recorded. Under ultrasound guidance, GON block was administered once a week for a total of four sessions. In the final session, 4 mg of dexamethasone was added to the local anesthetic for the steroid group (n:26). Pulsed radiofrequency (RF) treatment was applied to the RF group (n:25) just before the last session of the GON block. The pain course in the week following the procedure monthly average headache attack frequency, attack duration, VAS and the number of days analgesics were taken in a month were compared for both groups at 1-3-6 months. RESULTS: In the first month, a statistically significant decrease in attack frequency was observed in the RF group. However, no statistically significant differences were found between the groups in other findings at different time intervals. A significant decrease headache attack duration,VAS, and the number of days analgesics were taken in a month was observed in both treatment groups. Both treatments were found to be effective, but the effect size of the treatment was higher in the RF group compared to the steroid group. CONCLUSION: Although the results were better in the group receiving pulsed RF treatment, except for the attack frequency in the first month, no statistically significant superiority of one treatment method over the other was determined.

Unintentional Injection Into the Retrodural Space of Okada During Transforaminal Epidural Steroid Injection.

BACKGROUND: Transforaminal epidural steroid injection (TFESI) is commonly used for radicular pain, but can lead to an unintentional injection into the retrodural Space of Okada (RSO), an extradural space located dorsal to the ligamentum flavum, instead of the epidural space. OBJECTIVES: To determine the prevalence and describe the fluoroscopic imaging features of an unintentional injection into the RSO during a TFESI and to review the history of injections into the RSO. STUDY DESIGN: Observational study and original research. SETTING: This work was conducted at Jeju National University School of Medicine, Jeju, Republic of Korea. METHODS: A total of 5,429 lumbar TFESIs performed from the September 1, 2018 through October 31, 2021 were analyzed for unintentional RSO injections using fluoroscopic-guided contrast medium patterns. RESULTS: The rate of unintentional injection into the RSO was 0.20% (11 incidents). Contrast medium patterns in the RSO had a sigmoid or ovoid shape confined to the affected facet joint, or a butterfly-shaped pattern extending into the contralateral facet joint, but rarely extending beyond the upper or lower level. LIMITATION: The rarity of unintentional injection into the RSO prevented a randomized controlled study design. CONCLUSIONS: Careful fluoroscopic examination of contrast medium patterns during lumbar TFESI is crucial to identify needle placement in the RSO. If detected, the procedure can be corrected by slightly advancing the needle into the foramen.

Preoperative laboratory measurements as a predictor for nasal steroid irrigations after sinus surgery for chronic rhinosinusitis with nasal polyps.

PURPOSE: To assess whether preoperative C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), immunoglobulin E (IgE), and blood eosinophil percentage (EOS) can predict need for steroid irrigations after FESS. MATERIALS AND METHODS: Adult patients at BIDMC from inception until September 8, 2023 with chronic rhinosinusitis with nasal polyps who underwent FESS and had preoperative CRP (n = 129), ESR (n = 79), IgE (n = 107), or EOS (n = 125) were included. Labs were divided into normal (CRP: 0-5.0 mg/L; ESR: 0-15 mm/h; IgE: 150-300Ul/mL; EOS: 1-7 %) and high groups (CRP: >5.0 mg/L; ESR: >15 mm/h; IgE: >300Ul/mL; EOS: >7 %). The primary outcome was need for intranasal steroid irrigations after FESS (≤4 weeks, 4-12 weeks, 12-26 weeks, 26-52 weeks, 1-3 years, 3-5 years, and > 5 years). Receiver operating characteristic curves were created to determine thresholds for predicting postoperative steroid irrigations. RESULTS: Elevated IgE required intranasal steroid irrigation at 1-3 years (normal 34 %, high 62 %, p = 0.02), 3-5 years (normal 24 %, high 48 %, p = 0.04), and > 5 years (normal 19 %, high 43 %, p = 0.02). Elevated EOS required intranasal steroid irrigation at 26-52 weeks (normal 7 %, high 25 %, p = 0.009) and > 5 years (normal 19 %, high 46 %, p = 0.005). The area under the curve for IgE at 1-3 years was 0.696 (95 % CI: 0.597-0.795) with cutoff at 144-148 Ul/mL. CRP and ESR were not predictive of postoperative intranasal steroid treatment. CONCLUSIONS: Elevated IgE and EOS (but not CRP or ESR) may predict need for intranasal steroid treatment after FESS.

Combined Ultrasound and Fluoroscopy versus Ultrasound versus Fluoroscopy-Guided Caudal Epidural Steroid Injection for the Treatment of Unilateral Lower Lumbar Radicular Pain: A Retrospective Comparative Study.

Background and Objectives: This study aimed to evaluate the mid-term effectiveness and safety of a combined ultrasound (US) and fluoroscopy (FL)-guided approach in comparison to US-guided and FL-guided caudal epidural steroid injections (CESI) for treating unilateral lower lumbar radicular pain. Materials and Methods: A total of 154 patients who underwent CESI between 2018 and 2022 were included. Patients were categorized into three groups based on the guidance method: combined US and FL (n = 51), US-guided (n = 51), and FL-guided (n = 52). The study design was retrospective case-controlled, utilizing patient charts and standardized forms to assess clinical outcomes, adverse events, complications during the procedures. Results: In all groups, Oswestry Disability Index and Verbal Numeric Scale scores improved at 1, 3, and 6 months after the last injection, with no significant differences between groups (p < 0.05). The treatment success rate at all time points was also similar among the groups. Logistic regression analysis showed that injection method, cause, sex, age, number of injections, and pain duration did not independently predict treatment success. Blood was aspirated before injection in 2% (n = 1), 13.5% (n = 7), and 4% (n = 2) of patients in the combined US and FL groups, FL-guided groups, and US-guided groups, respectively. Intravascular contrast spread was detected in one patient in the combined method groups and seven in the FL-guided groups. Conclusions: When comparing pain reduction and functional improvement, there was no significant difference between the three methods. The combined method took less time compared to using FL alone. The combined approach also showed a lower occurrence of intravascular injection compared to using FL alone. Moreover, blood vessels at the injection site can be identified with an ultrasound using the combined method. Given these advantages, it might be advisable to prioritize the combined US- and FL-guided therapy when administering CESI for patients with unilateral lumbar radicular pain.

Comparison of the Use of Peripheral Nerve Stimulator and Quincke Needle for Lumbar Transforaminal Epidural Steroid Injections.

AIM: To compare the procedural features of transforaminal epidural steroid injection (TFESI) performed using two different needles (Stimuplex® and Quincke) in terms of procedure time, exposed radiation dose and adverse effects and complications, thus providing preliminary data to aid needle selection for TFESI. MATERIAL AND METHODS: Patients who received fluoroscopy-guided single-level lumbosacral TFESI between September 2020 and September 2021 were retrospectively included in this study. The patients were divided into two groups with respect to the needle type used for the procedure ? those treated with a Quincke needle were classified as Group Q and those treated with a Stimuplex® needle comprised Group S. Subsequently, the two groups were compared in terms of their demographic data, procedure time, radiation dose, amount of contrast use, first-hour numeric rating scale (NRS), intravascular flow and complication rates. RESULTS: The number of patients recruited for Groups Q and S was 65 and 61, respectively. No significant difference was observed between the groups regarding their demographic data, preprocedural NRS scores, procedure time, exposed radiation dose and the amount of contrast dye used. Notably, the first-hour NRS scores were found to be significantly lower in Group S (p=0.040) after the procedure. Moreover, the intravascular contrast spread was significantly different between the two groups (p < 0.05) ? it was encountered during four procedures in Group Q, but was altogether absent in Group S. CONCLUSION: The Stimuplex® needle may decrease the possibility of inadvertent intravascular leakages during TFESI and may also improve immediate pain scores after the procedure.

The clinical efficacy of single-hole punch excision combined with intralesional steroid injection for nodular keloid treatment: a self-controlled trial.

There are many methods to treat keloid, including various excision operations, laser, injection and radiotherapy. However, few studies have explored the effectiveness of single-hole punch excision in keloid treatment. This study aimed to investigate the efficacy and safety of lateral punch excision combined with intralesional steroid injection for keloid treatment through self-control trial. In this self-controlled trial, 50 patients meet the diagnosis of nodular keloid, and try to choose left-right symmetrical control, one skin lesion in the control group (50 skin lesionsin total) and the other in the observation group (50 skin lesions in total).The keloids in the treatment group were initially treated with punch excision combined with intralesional steroid injection, followed by injection treatment alone. Keloids in the control group received intralesional steroid injection alone. The Vancouver Scar Scale (VSS) of the keloid before and after the punch excision was evaluated; the keloid scores at different time points and the number of injection treatments required in both groups were compared, and adverse reactions were observed. The effective rate of the observation group was 86.0%, which was significantly higher than that of the control group (66.0%), and the recurrence rate of 22% was lower than that of the control group (χ2 = 4.141,63417), all of which were statistically significant (all P < 0.05). At the end of treatment, the VSS and total injection times in the observation group were significantly lower than those in the control group (t = 5.900,3.361), with statistical significance (P < 0.01). The combination of single-hole punch excision and intralesional steroid injection is an effective method to treat multiple nodular keloids, shortening the treatment course of tralesional steroid injection without obvious adverse reactions.

Assessment of symptomatic response to intravesical alkalinized lidocaine, bupivacaine, heparin and steroids in patients with bladder pain syndrome.

Bladder Pain Syndrome (BPS) is a puzzling and complicated disorder. 12 such patients, with a mean age 48.3 years, were treated with weekly intravesical instillation of admixture of alkalinized lidocaine, bupivacaine, heparin and steroids for six weeks. Evaluating the benefits of this therapy, patients experienced 82.2% & 90.9% relief at 3rd & 6th week of instillation. After completion of six cycles of therapy, patients experienced 68.7% & 65.3% relief at 3rd & 6th month follow up, concluding the early and long term relief of BPS.

Longitudinal evaluation of adverse events due to steroid use in primary immune thrombocytopenia: A population-based study.

This study aimed to investigate the association between the steroid use patterns and the risk of AEs in patients with primary immune thrombocytopenia (ITP). A total of 2691 newly diagnosed adults with ITP between 2011 and 2018 were identified from the National Health Insurance Research Database in Taiwan, and the date of first steroid use was defined as the index date. Post-index steroid use was calculated on a 90-day basis as a time-dependent variable and categorized by the average prednisolone-equivalent daily dose (<10 mg vs. ≥10 mg) and intensity (medication possession ratio <80% vs. ≥80%). Patients were followed up for 1 year from the index date for acute AE events, while chronic AEs were assessed until death, or end of 2019. Compared to patients with low-dose+low-intensity steroid use, those with high-dose+high-intensity steroid use were associated with a higher risk of acute AE (adjusted incident rate ratio [aIRR]: 1.57, 95% confidence interval [CI]: 1.38-1.78, p < 0.01) and chronic AE (aIRR: 1.26, 95% CI: 1.08-1.47, p < 0.01). Metabolic/endocrine and ophthalmologic disorders demonstrated the strongest correlation with a high dose and intensity. The joint effect of steroid dose and intensity was observed in patients with ITP, and the findings suggest that steroids should be used carefully.

Vascular complications and outcomes following transcatheter aortic valve replacement in patients on chronic steroid therapy: a meta-analysis.

BACKGROUND: Chronic steroid (CS) therapy was reportedly linked to increased vascular complications following percutaneous coronary intervention. However, its association with vascular complications after transcatheter aortic valve replacement (TAVR) remained uncertain, with conflicting results being reported. OBJECTIVE: The authors aimed to compare the rate of vascular complications and outcomes between patients with and without CS use after TAVR. METHODS: The authors conducted a comprehensive literature search in PubMed, Embase, and Cochrane databases from their inception until 18th April 2022 for relevant studies. Endpoints were described according to Valve Academic Research Consortium-2 definitions. Effect sizes were pooled using DerSimonian and Laird random-effects model as risk ratio (RR) with 95% CI. RESULTS: Five studies with 6136 patients undergoing TAVR were included in the analysis. The included studies were published between 2015 and 2022. The mean ages of patients in both study groups were similar, with the CS group averaging 80 years and the nonsteroid group averaging 82 years. Notably, a higher proportion of patients in the CS group were female (56%) compared to the nonsteroid group (54%). CS use was associated with a significantly higher risk of major vascular complications (12.5 vs. 6.7%, RR 2.32, 95% CI: 1.73-3.11, P <0.001), major bleeding (16.8 vs. 13.1%, RR 1.61, 95% CI: 1.27-2.05, P <0.001), and aortic annulus rupture (2.3 vs. 0.6%, RR 4.66, 95% CI: 1.67-13.01, P <0.001). There was no significant difference in terms of minor vascular complications (RR 1.43, 95% CI: 1.00-2.04, P =0.05), in-hospital mortality (2.3 vs. 1.4%, RR 1.86, 95% CI: 0.74-4.70, P =0.19), and 30-day mortality (2.9 vs. 3.1%, RR 1.14, 95% CI: 0.53-2.46, P =0.74) between both groups. CONCLUSION: Our study showed that CS therapy is associated with increased major vascular complications, major bleeding, and annulus rupture following TAVR. Further large multicenter studies or randomized controlled trials are warranted to validate these findings.

Type 1 Autoimmune Pancreatitis in Europe: Clinical Profile and Response to Treatment.

BACKGROUND & AIMS: Autoimmune pancreatitis (AIP) is an immune-mediated disease of the pancreas with distinct pathophysiology and manifestations. Our aims were to characterize type 1 AIP in a large pan-European cohort and study the effectiveness of current treatment regimens. METHODS: We retrospectively analyzed adults diagnosed since 2005 with type 1 or not-otherwise-specified AIP in 42 European university hospitals. Type 1 AIP was uniformly diagnosed using specific diagnostic criteria. Patients with type 2 AIP and those who had undergone pancreatic surgery were excluded. The primary end point was complete remission, defined as the absence of clinical symptoms and resolution of the index radiologic pancreatic abnormalities attributed to AIP. RESULTS: We included 735 individuals with AIP (69% male; median age, 57 years; 85% White). Steroid treatment was started in 634 patients, of whom 9 (1%) were lost to follow-up. The remaining 625 had a 79% (496/625) complete, 18% (111/625) partial, and 97% (607/625) cumulative remission rate, whereas 3% (18/625) did not achieve remission. No treatment was given in 95 patients, who had a 61% complete (58/95), 19% partial (18/95), and 80% cumulative (76/95) spontaneous remission rate. Higher (≥0.4 mg/kg/day) corticosteroid doses were no more effective than lower (<0.4 mg/kg/day) doses (odds ratio, 0.428; 95% confidence interval, 0.054-3.387) and neither was a starting dose duration >2 weeks (odds ratio, 0.908; 95% confidence interval, 0.818-1.009). Elevated IgG4 levels were independently associated with a decreased chance of complete remission (odds ratio, 0.639; 95% confidence interval, 0.427-0.955). Relapse occurred in 30% of patients. Relapses within 6 months of remission induction were independent of the steroid-tapering duration, induction treatment duration, and total cumulative dose. CONCLUSIONS: Patients with type 1 AIP and elevated IgG4 level may need closer monitoring. For remission induction, a starting dose of 0.4 mg/kg/day for 2 weeks followed by a short taper period seems effective. This study provides no evidence to support more aggressive regimens.

Contrast flow in CT-guided lumbar interlaminar epidural steroid injections: does needle position effect the laterality of contrast flow?

PURPOSE: To evaluate the effect of needle position on the laterality of contrast flow in CT-guided lumbar interlaminar epidural steroid injections. MATERIALS AND METHODS: A retrospective review of consecutive CT-guided interlaminar lumbar epidural steroid injections was performed. The terminal needle tip position (midline or lateral) and the laterality of epidural contrast were evaluated by two readers. Contrast flow pattern was classified as ipsilateral to needle trajectory, bilateral, or contralateral. Bilateral flow was further divided into asymmetric, symmetrical, or asymmetric to the contralateral side. Inter-reader agreement was calculated with the kappa statistic. The relationship of needle position to contrast laterality was calculated with the chi statistic. Pain scores were compared for bilateral and unilateral flows with a two-tailed T test for independent means. RESULTS: A total of 250 injections were included in 204 patients, with an age range of 24 to 93 years. The most commonly injected level (145/250) was L4-L5. Agreement between the two readers was almost perfect and substantial (kappa 0.751-0.880). The majority of injections (154/250) demonstrated contrast flow ipsilateral to the needle trajectory, 90/250 demonstrated bilateral flow, and 6/250 had contralateral flow. Of the 90 cases with bilateral flow, 80% were performed with a midline terminal needle position (p < 0.001). There was no difference in immediate post-procedure pain scores between patients with ipsilateral or bilateral contrast flow. CONCLUSION: For interlaminar epidural steroid injections, a midline terminal needle tip position has a greater probability of producing bilateral contrast flow compared to a lateral terminal needle tip position.

Effects of the preoperative use and dosage of steroids on postoperative complications of gastric cancer surgery.

PURPOSE: To investigate the effects of preoperative steroid administration, including dosage, on complications after gastrectomy for gastric cancer. METHODS: We reviewed patients who underwent gastrectomy for gastric and esophagogastric junctional adenocarcinoma between 2013 and 2019 at the Department of Gastrointestinal Surgery, The University of Tokyo. RESULTS: Among the total 764 patients eligible for inclusion in the study, 17 were on steroid medication preoperatively (SD group) and 747 were not (ND group). The hemoglobin, serum albumin levels, and respiratory functions were significantly lower in the SD group than in the ND group. The incidence of postoperative complications classified as Clavien-Dindo (C-D) ≥ 2 was significantly greater in the SD group than in the ND group (64.7% vs. 25.6%, p < 0.001). Intra-abdominal infection (35.2% vs. 9.6%, p < 0.001) and anastomotic leakage (11.8% vs. 2.1%, p < 0.001) occurred more frequently in the SD group than in the ND group. On multiple logistic regression analysis for C-D ≥ 3 postoperative complications, the odds ratio for oral steroid use ≥ 5 mg per day as prednisolone had the highest value, of 13.0 (95% confidence interval 2.46-76.2, p < 0.01). CONCLUSION: Preoperative oral steroid use was identified as an independent risk factor for postoperative complications after gastrectomy for gastric cancer. Furthermore, the complication rate appears to increase as the oral steroid dosage is increased.

Factors Associated with Treatment Success After Interlaminar Epidural Steroid Injection for Cervical Radicular Pain.

AIM: To investigate the demographic, clinical and radiological findings associated with treatment success after interlaminar epidural steroid injection (ILESI) in radicular pain induced by cervical disc herniation. MATERIAL AND METHODS: In this retrospective study, the data of patients who received cervical ILESI between January 2017 and June 2021 were screened. Of 223 patients, 92 with unilateral radicular neck pain due to cervical disc herniation were included. Demographic data, symptom duration, and numerical rating scale scores at baseline, at three weeks, three months, and six months after treatment were collected from the medical records of the patients. Disc herniation level, cervical axis, disc height, presence and degree of spinal canal and neural foraminal stenosis, vertebral endplate signal change, and definitive presence of uncovertebral and facet osteoarthritis were evaluated using cervical spine magnetic resonance imaging. Treatment success was determined as ?50% reduction in pain scores at six months compared to baseline. RESULTS: Data of 92 patients (27 men, 65 women) were included. The mean age was 50.82 ± 10.22 years, and the median symptom duration was 12 (4.25 to 20) months. At six months after ILESI, treatment was successful in 58 (58.7%) patients and unsuccessful in 34 (41.3%) patients. Multivariable logistic regression analysis was performed to identify the factors associated with treatment success at six months post-injection. In the final model, neural foraminal stenosis (non-severe vs. severe) and spinal canal stenosis (non-severe vs. severe) were significantly associated with the treatment success (OR=3.02, 95% CI=1.40?10.95, p=0.009; OR=5.31, 95% CI=1.77?15.85, p=0.003). CONCLUSION: Treatment success of cervical ILESI at six months is favorable. However, the presence of severe neural foraminal and spinal canal stenosis is associated with a reduced likelihood of treatment success.

Timosaponin AIII Suppresses RAP1 Signaling Pathway to Enhance the Inhibitory Effect of Paclitaxel on Nasopharyngeal Carcinoma.

Although PTX has been identified as an effective drug for nasopharyngeal carcinoma (NPC) therapy, it has serious side effects in the human body. Previous studies have shown that timosaponin AIII (TSAIII) can inhibit the malignant progression of NPC cells. This study investigated the active mechanism of the combination of TSAIII and paclitaxel (PTX) on NPC. Cellular viability, apoptosis, apoptotic factors, and RAP1 signaling regulators were detected in the PNC cells (CNE-1 and HNE-2) and the subcutaneous CNE-1 transplanted nude mice treated with PTX or/and TSAIII. The results showed that TSAIII notably strengthened the inhibitory effect of PTX on the proliferation of NPC cells CNE-1 and HNE-2; upregulated the expression of Bax B-cell lymphoma 2 (Bcl-2)/Bcl-xL-associated death promoter (Bad), and Ras-associated protein1 (RAP1) GTPase activating protein (Rap1GAP); inhibited the level of Bcl-2, RAP1, and Ras guanine nucleotide releasing protein (RasGRP2); and significantly enhanced the promoting effect of PTX on apoptosis in the CNE-1 and HNE-2 cells. Besides, TSAIII strengthened the inhibitory effect of PTX on xenograft tumor in nude mice without adverse reactions. In conclusion, the combination administration of TSAIII and PTX had a significantly therapeutic effect on NPC and avoided the PTX's side effects, which may have acted as a new direction for the study of therapeutic approaches for NPC clinically.

Tratamiento con inmunoglobulina intravenosa y esteroides sistémicos en pacientes con necrólisis epidérmica tóxica: Experiencia en un hospital en Ciudad de México / Use of Intravenous Immunoglobulins and Systemic Corticosteroids in Patients with Toxic Epidermal Necrolysis: Experience of a Hospital in Mexico City

La necrólisis epidérmica tóxica es la reacción secundaria a medicamentos más grave dentro del espectro de las reacciones mucocutáneas. El tratamiento multidisciplinario es clave para disminuir la mortalidad de los pacientes, además de la suspensión del fármaco causal. Existen pocos estudios de tratamientos farmacológicos en pacientes con necrólisis epidérmica tóxica en Latinoamérica que combinen el uso de esteroides sistémicos e inmunoglobulina intravenosa (IgIV). Describimos 6 casos de pacientes con necrólisis epidérmica tóxica tratados con esteroides sistémicos e IgIV en un hospital de referencia dermatológica en Ciudad de México. Ningún paciente falleció ni presentó complicaciones a corto y mediano plazo de seguimiento. En la mayoría de los casos se empleó una dosis de IgIV de 1g/kg por 3-5 días y 1g de metilprednisolona por 3-5 días. El tiempo de ingreso hospitalario fue de 14,8 días. La combinación de esteroides sistémicos e IgIv parece ser una opción segura en pacientes con necrólisis epidérmica tóxica (AU)

Toxic epidermal necrolysis is the most serious mucocutaneous adverse drug reaction. Multidisciplinary treatment and withdrawal of the causative drug are key to reducing mortality. Few studies have analyzed the use of systemic corticosteroids and intravenous immunoglobulins (IVIG) in patients with toxic epidermal necrolysis in Latin America. We describe our experience with 6 cases treated at a dermatology referral hospital in Mexico City. None of the patients died or developed complications in the short or medium term. The most widely used regimen was a combination of IVIG 1 g/kg for 3 to 5 days and methylprednisolone 1 g for 3 to 5 days. Mean hospital stay was 14.8 days. The combined use of systemic corticosteroids and IVIG seems to be a safe treatment option for patients with toxic epidermal necrolysis (AU)
