RESUMO
Immune checkpoint inhibitor (ICI) treatment has become an important therapeutic option for various cancer types. Although the treatment is effective, ICI can overstimulate the patient's immune system, leading to potentially severe immune-related adverse events (irAEs), including hepatitis, colitis, pneumonitis and myocarditis. The initial mainstay of treatments includes the administration of corticosteroids. There is little evidence how to treat steroid-resistant (sr) irAEs. It is mainly based on small case series or single case reports. This systematic review summarizes available evidence about sr-irAEs. We conducted a systematic literature search in PubMed. Additionally, we included European Society for Medical Oncology, Society for Immunotherapy of Cancer, National Comprehensive Cancer Network and American Society of Clinical Oncology Guidelines for irAEs in our assessment. The study population of all selected publications had to include patients with cancer who developed hepatitis, colitis, pneumonitis or myocarditis during or after an immunotherapy treatment and for whom corticosteroid therapy was not sufficient. Our literature search was not restricted to any specific cancer diagnosis. Case reports were also included. There is limited data regarding life-threatening sr-irAEs of colon/liver/lung/heart and the majority of publications are single case reports. Most publications investigated sr colitis (n=26), followed by hepatitis (n=21), pneumonitis (n=17) and myocarditis (n=15). There is most data for mycophenolate mofetil (MMF) to treat sr hepatitis and for infliximab, followed by vedolizumab, to treat sr colitis. Regarding sr pneumonitis there is most data for MMF and intravenous immunoglobulins (IVIG) while data regarding infliximab are conflicting. In sr myocarditis, most evidence is available for the use of abatacept or anti-thymocyte globulin (ATG) (both with or without MMF) or ruxolitinib with abatacept. This review highlights the need for prompt recognition and treatment of sr hepatitis, colitis, pneumonitis and myocarditis. Guideline recommendations for sr situations are not defined precisely. Based on our search, we recommend-as first line treatment-(1) MMF for sr hepatitis, (2) infliximab for sr colitis, followed by vedolizumab, (3) MMF and IVIG for sr pneumonitis and (4) abatacept or ATG (both with or without MMF) or ruxolitinib with abatacept for sr myocarditis. These additional immunosuppressive agents should be initiated promptly if there is no sufficient response to corticosteroids within 3 days.

The evidence- and consensus-based guideline on atopic eczema was developed in accordance with the EuroGuiDerm Guideline and Consensus Statement Development Manual. Four consensus conferences were held between December 2020 and July 2021. Twenty-nine experts (including clinicians and patient representatives) from 12 European countries participated. This first part of the guideline includes general information on its scope and purpose, the health questions covered, target users and a methods section. It also provides guidance on which patients should be treated with systemic therapies, as well as recommendations and detailed information on each systemic drug. The systemic treatment options discussed in the guideline comprise conventional immunosuppressive drugs (azathioprine, ciclosporin, glucocorticosteroids, methotrexate and mycophenolate mofetil), biologics (dupilumab, lebrikizumab, nemolizumab, omalizumab and tralokinumab) and janus kinase inhibitors (abrocitinib, baricitinib and upadacitinib). Part two of the guideline will address avoidance of provocation factors, dietary interventions, immunotherapy, complementary medicine, educational interventions, occupational and psychodermatological aspects, patient perspective and considerations for paediatric, adolescent, pregnant and breastfeeding patients.

INTRODUCTION: Drug-induced acute interstitial nephritis (DI-AIN) is an important cause of acute kidney injury. In renal biopsy specimens, tubulitis with eosinophilic infiltration is suggestive of DI-AIN. Although corticosteroid therapy and discontinuation of the offending drug can improve renal dysfunction in most cases of DI-AIN, some patients experience AIN recurrence, leading to corticosteroid dependency. Corticosteroid-dependent eosinophilic interstitial nephritis presents a difficult dilemma in diagnosis and information regarding optimum management is limited. PATIENT CONCERNS: A 25-year-old man, who received treatment with carbamazepine, zonisamide, valproate, and lacosamide for temporal lobe epilepsy, showed an increase in serum creatinine level from 0.98 to 1.29âmg/dL over a period of 6âmonths. Although he exhibited no symptoms, his serum creatinine level continued to increase to 1.74âmg/dL. DIAGNOSIS: Renal biopsy revealed tubulitis and interstitial inflammatory infiltrates with eosinophils. Immunological and ophthalmological examinations showed no abnormal findings, and thus, his renal dysfunction was presumed to be caused by DI-AIN. Although oral prednisolone (PSL) administration (40âmg/d) and discontinuation of zonisamide immediately improved his renal function, AIN recurred 10âmonths later. The increase in PSL dose along with discontinuation of valproate and lacosamide improved renal function. However, 10âmonths later, recurrent AIN with eosinophilic infiltration was confirmed by further biopsy. The patient was therefore diagnosed with corticosteroid-dependent eosinophilic interstitial nephritis. INTERVENTIONS: To prevent life-threatening epilepsy, carbamazepine could not be discontinued; hence, he was treated with an increased dose of PSL (60âmg/d) and 1500âmg/d of mycophenolate mofetil (MMF). OUTCOMES: MMF was well tolerated and PSL was successfully tapered to 5âmg/d; renal function stabilized over a 20-month period. LESSONS: The presence of underdetermined autoimmune processes and difficulties in discontinuing the putative offending drug discontinuation are contributing factors to corticosteroid dependency in patients with eosinophilic interstitial nephritis. MMF may be beneficial in the management of corticosteroid-dependent eosinophilic interstitial nephritis by reducing the adverse effects related to high-dose and long-term corticosteroid use.

Despite the widespread use of rabbit anti-thymocyte globulin (ATG) to prevent acute and chronic graft-versus-host disease (aGVHD, cGVHD) after allogeneic hematopoietic cell transplantation (allo-HCT), convincing evidence about an optimal dose is lacking. We retrospectively evaluated the clinical impact of two different ATG doses (5 vs 6-7.5 mg/kg) in 395 adult patients undergoing HSCT from matched unrelated donors (MUD) at 3 Italian centers. Cumulative incidence of aGVHD and moderate-severe cGVHD did not differ in the 2 groups. We observed a trend toward prolonged overall survival (OS) and disease-free survival (DFS) with lower ATG dose (5-year OS and DFS 56.6% vs. 46.3%, p=0.052, and 46.8% vs. 38.6%, p=0.051, respectively) and no differences in relapse incidence and non-relapse mortality. However, a significantly increased infection-related mortality (IRM) was observed in patients who received a higher ATG dose (16.7% vs. 8.8% in the lower ATG group, p=0.019). Besides, graft and relapse-free survival (GRFS) was superior in the lower ATG group (5-year GRFS 43.1% vs. 32.4%, p=0.014). The negative impact of higher ATG dose on IRM and GRFS was confirmed by multivariate analysis. Our results suggest that ATG doses higher than 5 mg/kg are not required for MUD allo-HCT and seem associated with worse outcomes.

A 35-year-old male patient with end-stage renal disease due to vesicoureteral reflux preemptively received a renal graft from his father. The patient had a history of allergy to contrast-enhancing media. He received oral tacrolimus (TAC) and mycophenolate mofetil without any problems for 2 days before kidney transplantation. During the induction period of the surgery, his systolic blood pressure (sBP) decreased to 60 mmHg approximately 1 hour after initiating intravenous tacrolimus (TAC-IV) and intravenous piperacillin (PIPC), and the anesthesiologist suspected drug-induced anaphylaxis and stopped administration of the medications. Because TAC had been administered preoperatively without any adverse events, PIPC was suspected as the causative agent of the anaphylaxis. After the patient's hemodynamics returned to baseline, TAC-IV was restarted. However, his sBP rapidly decreased to 40 mmHg and the patient developed wheezing. He was diagnosed with drug-induced anaphylaxis due to castor oil derivatives in the TAC-IV formulation. The patient's sBP was restored with the administration of some vasopressors, and kidney transplantation was then performed without difficulty. Two days after kidney transplantation, oral TAC was administered without anaphylaxis. Clinicians should consider that not only the drug itself but also its additives or metabolites could induce anaphylaxis.

Idiopathic membranous nephropathy (IMN), a common pathological type of nephrotic syndrome, is one of the main causes of kidney failure. With an increasing prevalence, IMN has received considerable attention in China. Based on recent studies, we discuss advances in the diagnosis of IMN and the understanding of its genetic background. Although the pathogenesis of IMN remains unclear, our understanding has been substantially enhanced by the discovery of new antigens such as phospholipase A2 receptor, thrombospondin type-1 domain-containing 7A, exostosin1/exostosin2, neural epidermal growth factor-like 1 protein, neural cell adhesion molecule 1, semaphorin 3B, and factor H autoantibody. However, due to ethnic, environmental, economic, and lifestyle differences and other factors, a consensus has not yet been reached regarding IMN treatment. In view of the differences between Eastern and Western populations, in-depth clinical evaluations of biomarkers for IMN diagnosis are necessary. This review details the current treatment strategies for IMN in China, including renin-angiotensin system inhibitors, corticosteroid monotherapy, cyclophosphamide, calcineurin inhibitors, mycophenolate mofetil, adrenocorticotropic hormone, and traditional Chinese medicine, as well as biological preparations such as rituximab. In terms of management, the 2012 Kidney Disease Improving Global Outcomes (KDIGO) clinical practice guidelines do not fully consider the characteristics of the Chinese population. Therefore, this review aims to present the current status of IMN diagnosis and treatment in Chinese patients, and includes a discussion of new approaches and remaining clinical challenges.

INTRODUCTION: Mycophenolate mofetil and its active metabolite mycophenolic acid are routinely used as immunosuppressant drugs in solid organ transplantation in a fixed daily dose regimen in association with cyclosporine, tacrolimus and steroids. Therapeutic drug monitoring for mycophenolic acid concentration has been suggested to optimize outcomes by reducing rejection and drug related toxicities in clinical renal transplantation. AIM: To determine the predose concentration of mycophenolic acid in renal transplanted patients by a validated proposed high-performance liquid chromatography (HPLC) method and to estimate the interindividual variability based on the therapeutic target. MATERIALS AND METHODS: An HPLC method combined with protein precipitation has been validated for mycophenolic acid determination in the human plasma obtained from 21 renal transplant recipients. HPLC analysis was carried out using the chromatographic system Agilent Technologies 1200 DAD. Samples were injected manually, and the compounds were separated on a LiChrosphere® select B C18 analytical column. The mobile phase was 45:55 (v/v) acetonitrile-buffer phosphate, pH 2.5, flow rate of 1.0 mL/min and column temperature of 30°C. Detection was performed at 215 nm. Whole blood samples were collected into vacutainers containing EDTA and separated at 6000 g for 10 minutes. A 200-µL aliquot of patient plasma was transferred to a tube, followed by addition of 10 µL of naproxen as internal standard and 400 µL of acetonitrile (v/v) as a protein precipitating agent. Each tube was vortex-mixed for 30 sec and then centrifuged for 10 min at 10000 rpm. 20 µL of the supernatant was injected into the HPLC system for analysis. RESULTS: The method showed appropriate linearity for MPA with correlation coefficient greater than 0.999. High inter-patient variability is observed with 18% of patients within the target trough concentration range, 27% of patients below the target trough concentration range and 54% over the range with risk of toxicity. CONCLUSIONS: Therapeutic monitoring of MPA might contribute to a better management of renal transplant recipient with the goal of optimizing therapeutic regimens in order to reduce the risk of rejection and MPA-related toxicity.

BACKGROUND: Most patients with autoimmune hepatitis (AIH) respond to a combination of prednisolone and azathioprine. For patients who are intolerant or refractory to azathioprine, proposed alternative therapies are based on scarce data, limited to transplant centres and with short-term follow-up periods. OBJECTIVE: To evaluate the long-term efficacy and safety of MMF as a second-line therapy in patients with AIH managed at a tertiary non-transplant centre. METHODS: Retrospective analysis of a prospectively collated database identified AIH patients who received MMF from 2006 to 2015. Clinical, biochemical and immunological parameters were assessed at 3-, 6- and 12-months, and at last follow-up. Biochemical response (BR) was defined as improvement of transaminases, complete remission (CR) as normalisation of transaminases and IgG, while others were considered non-responders (NR). RESULTS: Eighteen out of 151 (12%) AIH patients received MMF. Nine received MMF due to azathioprine-intolerance (group 1), while nine due to refractory disease (group 2). In group 1, CR and BR was achieved in six (67%) and two (22%) patients respectively. In group 2, CR and BR was achieved in one (11%) and five (56%) patients respectively. Adverse events occurred in eight patients (44%), with one patient requiring drug discontinuation. After a medium follow-up of 78 (31-116) months, there was a significant decrease in transaminase levels, mirrored by decrease in prednisolone dose from 25 to 6.25 mg/day (P<0.05). CONCLUSION: Long-term therapy with MMF is safe and effective in AIH patients requiring second-line therapies, and these patients can be effectively managed at tertiary non-liver transplant centres.

La neumonía intersticial con características autoinmunes por sus siglas en inglés, es una entidad en la que existe un compromiso pulmonar intersticial y hallazgos clínicos y paraclínicos que sugieren una enfermedad del tejido conectivo, aunque no cumplen criterios diagnósticos para ninguna de estas. Con fines de investigación, en el 2015 se describieron criterios para esta entidad, en los que se incluyeron características de los dominios clínicos, serológicos y morfológicos, con diversos patrones de compromiso pulmonar. En la actualidad, hay un aumento en el interés de esta entidad, pues algunos autores sugieren que se pueda tratar de una enfermedad autoinmune per se, cuyo órgano blanco principal sería el pulmón. Dado su reciente reconocimiento, son pocos los casos descritos en la literatura. Con el propósito de contribuir a la mejor identificación de esa entidad, presentamos el caso de una paciente de 68 años con afectación pulmonar en quien después de descartar otras causas se llegó al diagnóstico de neumonía intersticial con características autoinmunes al cumplir los criterios de cada dominio requerido. Se inició tratamiento con micofenolato mofetilo a dosis de 2,5 mg/día. En su evolución clínica, la paciente presentó mejoría y fue dada de alta con tratamiento ambulatorio(AU)
Interstitial pneumonia with autoimmune features is a condition in which patients can have clinical and serological findings suggesting of a connective tissue disease associated with an interstitial lung disease, nonetheless no criteria for an specific connective tissue disease are meeting. In 2015 classification criteria where proposed, the diagnosis is made in the presence of a combination of features from clinical, serological and morphological domain with various patterns of pulmonary involvement. Currently there is an increase in the interest of this condition, as some authors suggest that it can be an autoimmune pathology per se, whose main target organ would be the lung. Given its recent recognition, there are few cases described in the literature and therefore in order to contribute to the better identification of that entity, we present the case of a 65 year old patient with lung involvement in whom after ruling out other etiological causes reached the diagnosis of I Interstitial pneumonia with autoimmune by meeting criteria of each required domain(AU)

COVID-19 has become a global concern. A large number of reports have explained the clinical characteristics and treatment strategies of COVID-19, but the characteristics and treatment of COVID-19 patient with systemic lupus erythematosus (SLE) are still unclear. Here, we report the clinical features and treatment of the first SLE patient with confirmed COVID-19 pneumonia. This was a 39-year-old woman, diagnosed with SLE 15 years ago, whose overall clinical characteristics (symptoms, laboratory tests, and chest CTs) were similar to those of the general COVID-19 patients. She continued to take the previous SLE drugs (doses of glucocorticoids, hydroxychloroquine, and immunosuppressive agents were not reduced) and was treated with strict antiviral and infection prevention treatment. After the first discharge, she got a recurrence of COVID-19 during her home isolation, and then returned to hospital and continued the previous therapy. Finally, this long-term immune suppressive patient's COVID-19 was successfully cured. The successful recovery of this case has significant reference value for the future treatment of COVID-19 patients with SLE. Key Points ⢠COVID-19 patients with SLE is advocated to continue the medical treatment for SLE. ⢠Hydroxychloroquine may have potential benefits for COVID-19 patients with SLE. ⢠COVID-19 patients with SLE is prone to relapse, and multiple follow-ups are necessary.

Paediatric morphoea is a debilitating fibrosing disorder of uncertain aetiology, affecting the skin and subcutaneous tissues. Defining optimum management strategies in paediatric morphoea remains an ongoing challenge, owing to the varied presentations and a relative paucity of paediatric-specific studies. We performed a literature search on PubMed, MEDLINE and Google Scholar, using keywords such as 'pediatric morphea', 'juvenile localised scleroderma' and 'juvenile systemic sclerosis'. Relevant studies, including randomized trials, reviews of standard current guidelines and original research articles, were selected and results analysed before summarizing them. In Part 1 of this review, we described the epidemiology, aetiopathogenesis and clinical classification; in this part, we discuss the diagnosis, markers of disease activity, management and natural history in paediatric morphoea.

OBJECTIVE: To update the 2012 EULAR/ERA-EDTA recommendations for the management of lupus nephritis (LN). METHODS: Following the EULAR standardised operating procedures, a systematic literature review was performed. Members of a multidisciplinary Task Force voted independently on their level of agreeement with the formed statements. RESULTS: The changes include recommendations for treatment targets, use of glucocorticoids and calcineurin inhibitors (CNIs) and management of end-stage kidney disease (ESKD). The target of therapy is complete response (proteinuria <0.5-0.7 g/24 hours with (near-)normal glomerular filtration rate) by 12 months, but this can be extended in patients with baseline nephrotic-range proteinuria. Hydroxychloroquine is recommended with regular ophthalmological monitoring. In active proliferative LN, initial (induction) treatment with mycophenolate mofetil (MMF 2-3 g/day or mycophenolic acid (MPA) at equivalent dose) or low-dose intravenous cyclophosphamide (CY; 500 mg × 6 biweekly doses), both combined with glucocorticoids (pulses of intravenous methylprednisolone, then oral prednisone 0.3-0.5 mg/kg/day) is recommended. MMF/CNI (especially tacrolimus) combination and high-dose CY are alternatives, for patients with nephrotic-range proteinuria and adverse prognostic factors. Subsequent long-term maintenance treatment with MMF or azathioprine should follow, with no or low-dose (<7.5 mg/day) glucocorticoids. The choice of agent depends on the initial regimen and plans for pregnancy. In non-responding disease, switch of induction regimens or rituximab are recommended. In pure membranous LN with nephrotic-range proteinuria or proteinuria >1 g/24 hours despite renin-angiotensin-aldosterone blockade, MMF in combination with glucocorticoids is preferred. Assessment for kidney and extra-renal disease activity, and management of comorbidities is lifelong with repeat kidney biopsy in cases of incomplete response or nephritic flares. In ESKD, transplantation is the preferred kidney replacement option with immunosuppression guided by transplant protocols and/or extra-renal manifestations. Treatment of LN in children follows the same principles as adult disease. CONCLUSIONS: We have updated the EULAR recommendations for the management of LN to facilitate homogenization of patient care.

There are data available in the literature on bioelement concentrations in the serum of various groups of patients; however, very little is known about the serum concentration of selenium (Se), iron (Fe), zinc (Zn), and copper (Cu) in renal transplant patients treated with immunosuppressive drugs, including mycophenolate mofetil (MMF). Monitoring of serum bioelement concentrations in renal transplant recipients is of profound importance, as the proper bioelement levels seem to prolong the normal function of the transplanted organ. Thus, the aim of this current study was to examine and carry out comparative analysis involving serum concentrations of Se, Fe, Cu, and Zn of renal transplant recipients treated with MMF and without MMF. The material consisted of blood samples from 115 patients of the Department of Nephrology, Transplantology, and Internal Medicine of Independent Public Clinical Hospital No. 2, Pomeranian Medical University, in the city of Szczecin in the northwestern Poland. Serum Se, Fe, Cu, and Zn levels were quantified by inductively coupled mass spectroscopy (ICP-MS). Taking into account all patients, MMF increases Cu level. Cu and Fe concentrations were significantly higher in women treated with MMF; in group of younger patients treated with MMF, Se level was significantly lower comparing with those whose regimen did not include MMF. Additionally, MMF in combination with prednisone increased Se concentration in blood of transplant recipients. Our study highlights that trace elements should be monitored to allow for an early detection of trace elements deficits, which can easily be corrected for by an adjusted diet or supplemental intake.

Juvenile localized scleroderma (jLS) is an orphan disease that can lead to cosmetic disfiguration and orthopedic problems. Two recent publications review the current recommendations regarding diagnosis, assessment, follow up and treatment of pediatric localized scleroderma cases, both of which suggest the Localized Scleroderma Cutaneous Assessment Tool as an important instrument to assess activity and damage. This review focuses on the systemic treatment of jLS. Systemic treatment includes synthetic and biologic disease-modifying antirheumatic drugs. Systemic therapy is indicated if the lesion crosses any joint, or leads to potential cosmetic disfiguration or orthopedic problems. The only controlled trial of systemic treatment has shown the efficacy of methotrexate, which is the first choice of treatment. It appears superior to phototherapy according to a recently published meta-analysis. In case of methotrexate intolerance, mycophenolate mofetil is an option. In case of methotrexate nonresponse, addition of mycophenolate mofetil, tocilizumab or abatacept seems to be effective. Future treatment options derived and extrapolated from adult trials regarding treatment of skin involvement of systemic scleroderma or fibrosis are promising, as the final pathway in the skin seems to be similar in both diseases.

Interstitial lung disease (ILD) is one of the major causes of morbidity and mortality in patients with connective tissue disease (CTD) and the treatments available until nowadays are in most cases unable to halt disease progression. CTD-ILD pathogenesis includes an initial inflammatory phase, followed by a fibrotic phase, in which extracellular matrix proteins are produced and fibrotic scaring tissue within the lung develops. Steroids and immunosuppressants are the weapons we currently have to treat CTD-ILD. However, mortality rates remain high and identification of new therapeutic targets is crucial. Antifibrotic drugs, which include nintedanib and pirfenidone, have been approved for the treatment of idiopathic pulmonary fibrosis (IPF) and due to similar pathogenesis between IPF and CTD-ILD, their use seems attractive in patients with CTD-IL. We report 3 cases of patients with different CTDs, with predominantly fibrotic changes in high resolution computed tomography that progressed despite immunosuppression, and who have attained disease stability after introduction of antifibrotic drugs.

Lichen planus (LP) is a chronic-relapsing inflammatory skin disease. Although many drugs have been used for the management of LP, some of them lack the backup by strong therapeutic evidence, while others are not suitable for some patients due to safety profile issues. The aim of this study was to review the recent status of available medical therapies for LP to help physicians make better decisions upon best medical practice while facing patients with this condition. A review of published articles on management of LP was conducted with the MEDLINE and PubMed databases. The quality of the evidence was graded as high, moderate, low or very low. A total of 1366 articles were retrieved, and 219 (16%) were included in the final analysis. Twenty-one different treatment modalities were analysed. The quality of evidence was high for topical steroid and calcineurin inhibitor, while it was moderate for oral steroids. All the other modalities reached low or very low quality of evidence. Topical steroids and calcineurin inhibitors are the current first-line therapies, while for other therapies the strength of recommendation is not so evident. Unfortunately, larger randomized, controlled trials to support the efficacy, safety and tolerability of other therapies in LP are lacking, and many of them are recommended based on studies with small sample sizes, lack of standardized outcome measures or lack of controlled duration or even in anecdotal evidence. Thus, large-scale randomized clinical trials are still warranted to establish the exact benefits of other topical treatments, phototherapy, immunosuppressant and new immunomodulators for an optimized treatment of LP.

Thrombotic microangiopathy (TMA) is a pathologic condition characterized by microangiopathic hemolytic anemia, thrombocytopenia, and organ injury due to microvascular endothelial lesions and thrombosis. It occurs in a variety of diseases and, unless recognized and treated, leads to severe morbidity and mortality. We present the case of a 48-year-old woman who underwent lung transplantation, initially under tacrolimus, mycophenolate mofetil (MMF), and prednisolone. Several complications emerged in the following months, including abdominal aortic and left renal artery thrombosis and cutaneous infections, although her renal function remained normal. Six months after transplant, her renal function began to deteriorate, which was assumed to be due to elevated tacrolimus levels and doses were adjusted. Due to leukopenia, MMF was changed to everolimus. One year after, she was admitted with fatigue, anemia, and renal dysfunction. Complementary exams revealed only iron deficiency, leukopenia, normal platelets, and elevated lactate dehydrogenase; her renal ultrasound was normal. A renal biopsy was performed and thrombotic microangiopathy was subsequently identified as the main cause of the renal dysfunction. Tacrolimus was therefore discontinued and MMF restarted with slow improvement of renal function. Only when everolimus was stopped did the patient's renal function show incremental improvement. TMA may be a serious complication after lung transplantation and the risk is higher when a combination of tacrolimus and everolimus is used. Renal biopsy findings are essential to confirm the final diagnosis of TMA, allowing for a change in immunosuppression to prevent permanent and severe renal damage.

Disabling pansclerotic morphea of childhood (DPMC) is a rare subtype of juvenile localized scleroderma (JLS) characterized by pansclerosis mainly affecting children under the age of 14. This aggressive disease has a poor prognosis due to the rapid progression of deep musculoskeletal atrophy resulting in cutaneous ulceration and severe joint contractures. We describe the challenges in treating a previously well 5-year-old male who has refractory symptoms of DPMC. Over the 29 months, since his initial presentation, we trialed over ten therapies. There was subjective improvement with prednisolone and mycophenolate mofetil (MMF). However, other therapies including biologics and tyrosine kinase inhibitors (TKI) were ineffective. The patient has been referred for hematopoietic stem cell transplant given ongoing disease progression. We conducted a literature search focusing on English articles with keywords including DPMC. Publications with limited information or describing cases aged 20 and above were excluded. Thirty-seven case reports were identified and the reported treatments were evaluated. Methotrexate and corticosteroids have been the most commonly utilized. MMF has been anecdotally effective. Biologics, TKI, and Janus kinase inhibitors lack evidence in DPMC, but have had demonstrated efficacy in similar pathologies including systemic sclerosis, and, thus, have been used for DPMC. Phototherapy has been documented to be reducing skin thickness and stiffness of plaques. Eventually, most children require multi-modal and high-dose immunosuppressive therapies to reduce the inflammation inflicted by the disease. Long-term antibiotics and nutritional support are important in the ongoing care of these patients.

Graves' orbitopathy is a debilitating disorder which occurs in patients with autoimmune thyroid disease, mainly Graves' disease, and adds layers of complexity to management of both conditions. We conducted a comprehensive review of literature for publications relating to established and new management options for Graves' orbitopathy and have summarized key articles in this review. Initial evaluation of patients with Graves' disease should also include clinical evaluation for orbitopathy. If eye disease is present, patients are best managed by a multi-specialty team including an endocrinologist and ophthalmologist. All patients with Graves' orbitopathy benefit from risk factor modification and normalization of thyroid function tests. Patients with active, mild disease generally benefit from local therapies and selenium, while patients with moderate-to-severe disease usually require the addition of intravenous glucocorticoid therapy. If there is an inadequate response to glucocorticoid therapy, several second-line therapies have been investigated for use, including orbital radiotherapy (with additional glucocorticoids), rituximab, cyclosporine, mycophenolate mofetil, and methotrexate. Use of new biologic agents, mainly teprotumumab and tocilizumab, have demonstrated impressive reductions in disease activity and severity. If these results are confirmed, the treatment paradigm is likely to change in the future. Finally, there are several novel immunotherapies being investigated for Graves' disease, which may have treatment implications for Graves' orbitopathy as well. Overall, there are many encouraging advances in the therapy of Graves' orbitopathy that are making the future more promising for patients suffering from this disease.

Background: Although numerous medications are available for the treatment of cutaneous lichen planus (CLP), recurrence is common and there is a lack of evidence of efficacy of many treatment options. Part 1 reviewed consolidated evidence from topical therapies and phototherapy. In Part 2, all systemic treatments are assessed. Methods: All English studies, regardless of design, investigating the outcome of systemic treatment for CLP, until January 2018, were included. While there were only a few well-designed randomized control trials (RCTs), evidence was extrapolated and graded from open trials, case series as well as case reports. Results: Mini pulse therapy with corticosteroids should be considered over moderate daily dosing with retinoids being an alternative option. Low-dose methotrexate is considered effective and safe provided it is regularly monitored. Azathioprine, cyclosporine and mycophenolate mofetil require larger more defined RCTs in resistant CLP. Low-molecular-weight heparins may be considered in patients with no response to first-line treatment. Biologics are potentially promising but there is a need for RCTs with a considerable duration to determine their long-term safety profiles. Evidence with various other drugs were reported. Conclusion: Clinicians may have a broader perspective on the efficacy of treatments across all study profiles.
