During the 1-year observation period, 18 (24%) patientsexperienced a relapse, and both the FC and UCCIS of the relapse group were significantly higher than that of theremission group. The cut-off values for predicting relapse were set at FC = 323 mg/kg and UCCIS = 10.2. The areaunder the curve of the receiver-operating characteristic analysis for predicting relapse did not show a significantdifference between FC and UCCIS. The accuracy of the endoscopic scores and biomarkers in predicting relapse was86.7% for UCCIS, 85.3% for UCEIS, 76.0% for FC, and 73.3% for MES.CONCLUSIONThe three endoscopic scores and FC may predict UC relapse during clinical remission. Among these scores, UCEISmay be the most useful in terms of ease of evaluation and accuracy.展开更多

Relapsed clubfoot is the residual deformity that remains after single or multiple surgical interventions. Severely neglected clubfoot rarely exists today in developed countries, except in some emigrants from low- and middle-income countries. Acute surgical management with corrective mid-foot osteotomy and elongation of the Achilles tendon has an excellent functional outcome. Objective: To assess the functional outcome of acute correction of neglected Talipes-quinoa-varus deformity in adults. Methods: This is a cross-sectional, hospital–based multi-centric study. Forty patients were included in this study. Midfoot osteotomy and elongation of the Achilles tendon were performed on all patients. Data was collected using a questionnaire and the functional outcome has been assessed using the American Orthopedic Foot and Ankle Society Score (AOFAS). This score was measured before surgery and one year after surgery. Results: the mean age was 19.9 ± 4.7 years. Males were 25 (62.5%) and females were 15 (37.5%). The mean preoperative AOFAS score was 37.7 ± 7.1 (poor). This score improved to 80.7 ± 13.7 (good to excellent), two years after surgery. However, this indicates a significant change in the functional outcome after the operation (p value Conclusion: acute correction of neglected and relapsed TEV with elongation of the Achilles tendon and single midfoot osteotomy has excellent functional outcome as assessed by AOFAS Score. The satisfaction with this procedure is impressive. The younger age population showed better outcomes with this procedure.展开更多

文摘We are writing in response to the paper published in the World Journal of Gastroenterology by Zhou et al.The authors identified higher serum immunoglobulin(Ig)G4 levels and age over 55 years as independent risk factors for disease relapse.Despite notable strengths,it is crucial to address potential biases.Firstly,the cohort study included 189 patients with autoimmune pancreatitis(AIP)type 1(with higher IgG4 seropositivity and higher relapse)and 24 with type 2(with lower IgG4 seropositivity and lower relapse).Consequently,most,if not all,AIP type 2 patients were assigned to the normal group,possibly inflating the association of higher serum IgG4 levels with relapse and potentially exaggerating the association of older age with relapse.Secondly,the authors did not provide sufficient details regarding AIP diagnosis,such as the ratio of definitive vs probable cases and the proportion of biopsies.In cases where histological evidence is unavailable or indeterminate,AIP type 2 may be misdiagnosed as definitive type 1,and type 1 may also be misdiagnosed as probable type 2,particularly in cases with normal or mildly elevated serum IgG4 levels.Lastly,in this retrospective study,approximately one-third of the consecutive patients initially collected were excluded for various reasons.Accordingly,the impact of nonrandom exclusion on relapse outcomes should be carefully considered.In conclusion,the paper by Zhou et al offers plausible,though not entirely compelling,evidence suggesting a predictive role of elevated serum IgG4 levels and advanced age in AIP relapse.The foundation for future investigations lies in ensuring a reliable diagnosis and accurate disease subtyping,heavily dependent on obtaining histological specimens.In this regard,endoscopic ultrasound-guided fine-needle biopsy emerges as a pivotal component of the diagnostic process,contributing to mitigating biases in future explorations of the disease.

文摘Tumor-promoting niche after incomplete surgery resection(SR)can lead to more aggressive local progression and distant metastasis with augmented angiogenesis-immunosuppressive tumor microenvironment(TME).Herein,elevated neutrophil extracellular traps(NETs)and cancer-associated neurotransmitters(CANTs,e.g.,catecholamines)are firstly identified as two of the dominant inducements.Further,an injectable fibrin-alginate hydrogel with high tissue adhesion has been constructed to specifically co-deliver NETs inhibitor(DNase I)-encapsulated PLGA nanoparticles and an unselectiveβ-adrenergic receptor blocker(propranolol).The two components(i.e.,fibrin and alginate)can respond to two triggers(thrombin and Ca2+,respectively)in postoperative bleeding to gelate,shaping into an interpenetrating network(IPN)featuring high strength.The continuous release of DNase I and PR can wreck NETs and antagonize catecholamines to decrease microvessel density,blockade myeloid-derived suppressor cells,secrete various proinflammatory cytokines,potentiate natural killer cell function and hamper cytotoxic T cell exhaustion.The reprogrammed TME significantly suppress locally residual and distant tumors,induce strong immune memory effects and thus inhibit lung metastasis.Thus,targetedly degrading NETs and blocking CANTs enabled by this in-situ IPN-based hydrogel drug depot provides a simple and efficient approach against SR-induced cancer recurrence and metastasis.
文摘Dengue virus infection is endemic in India with seasonal variations.It can lead to lethal consequences with plasma leakage and/or bleeding[1,2].Dengue shock syndrome has high mortality in developing countries like India.Dengue can cause functional proteinuria and even heavy proteinuria[3-6].Though dengue has been implicated to cause glomerulonephritis[7],to the best of our knowledge,dengue as a cause of relapse of minimal change disease(MCD)has not been reported.
文摘Evaluating the cluster formation of clinical attacks in chronic relapsing diseases is an important statistical issue because the presence of attack clusters may influence therapeutic strategies for relapse prevention.We recently reported the occurrence of unevenly clustered attacks in patients with anti-aquaporin-4(AQP4)antibody-positive neuromyelitis optica spectrum disorder(NMOSD)(Akaishi et al.,2020a).
文摘BACKGROUND Ovarian cancer is the most common malignant tumor of the female reproductive system,and the survival rate of patients with relapsed and refractory ovarian cancer is very low.CASE SUMMARY Here,we report a case of high-grade serous papillary adenocarcinoma of the ovary that was successfully treated with immunotherapy.Radical surgery and adjuvant chemotherapy for the 56-year-old patient were successful;however,her tumor relapsed.Subsequent second-line chemotherapy,targeted agents,and other treatments were ineffective,as the tumor continued to recur and metastasize.Anti-programmed cell death-1(PD-1)monotherapy(tislelizumab)completely alleviated the tumor,and the multiple metastatic tumors disappeared.To date,the patient has used anti-PD-1 for 32 months,experiencing no disease progression and maintaining good health without additional treatment.CONCLUSION This case suggests that anti-PD-1 immunotherapy may have long-term positive effects on outcomes in some refractory recurrent solid tumors.Further research is needed to identify patients most likely to respond to anti-PD-1 therapy.
文摘Symptomatic cyclops lesions are complications that can be seen at rates of up to approximately 10%after anterior cruciate ligament reconstruction.However,recurrent cyclops lesions have rarely been documented.There are case rare series in the literature regarding the treatment of recurrent cyclops lesion.Future large studies are needed to investigate factors contributing to the development of cyclops lesions and syndrome and treatment options.

文摘Introduction Nitrous oxide(N2O/laughing gas)has been used in medical practice as an inhalational anaesthetic and analgesic for more than 150 years.1 In the past decades,N2O exhibited increasing popularity among recreational drug users for its euphoric effects,potentially through its interaction with the endogenous opioid system.2 Recreational use of N2O emerged as the seventh most used drug globally in the past decade.3 The use of N2O can cause myelopathy,myocardial injury,anaemia,severe mood disorders,sensory and motor neuropathy,and psychotic symptoms.45 Prolonged N2O intake results in vitamin B12 deficiency and inhibits methionine synthetase,folate and DNA production,leading to plasma homocysteine(HCY)level elevation and bone marrow haematopoietic dysfunction.6 This study aimed to investigate the neurological symptoms of nitrous oxide use and then explore the relapse trajectory and risk factors for relapse.
文摘BACKGROUND Although the usefulness of endoscopic scores,such as the Mayo Endoscopic Subscore(MES),Ulcerative Colitis Endoscopic Index of Severity(UCEIS),and Ulcerative Colitis Colonoscopic Index of Severity(UCCIS),and biomarkers such as fecal calprotectin(FC)for predicting relapse in ulcerative colitis(UC)has been reported,few studies have included endoscopic scores for evaluating the entire colon.AIM To compare the usefulness of FC value and MES,UCEIS,and UCCIS for predicting relapse in patients with UC in clinical remission.METHODS In total,75 patients with UC in clinical and endoscopic remission who visited our institution between February 2019 and March 2022 were enrolled.The diagnosis of UC was confirmed based on the clinical presentation,endoscopic findings,and histology,according to the current established criteria for UC.Fecal samples were collected the day before or after the colonoscopy for measurement of FC.Endoscopic evaluations were performed using MES,UCEIS,and UCCIS.The primary outcome measure of this study was the assessment of the association between relapse within 12 mo and MES,UCEIS,UCCIS,and FC.The secondary outcome was the comparison between endoscopic scores and biomarkers in en-rolled patients with UC with mucosal healing.RESULTSFC and UCCIS showed a significant correlation with UCEIS (r = 0.537, P < 0.001 and r = 0.957, P < 0.001, respectively).Receiver-operating characteristic analysis for predicting MES 0 showed that the area under the curve ofUCCIS was significantly higher than that of FC (P < 0.01). During the 1-year observation period, 18 (24%) patientsexperienced a relapse, and both the FC and UCCIS of the relapse group were significantly higher than that of theremission group. The cut-off values for predicting relapse were set at FC = 323 mg/kg and UCCIS = 10.2. The areaunder the curve of the receiver-operating characteristic analysis for predicting relapse did not show a significantdifference between FC and UCCIS. The accuracy of the endoscopic scores and biomarkers in predicting relapse was86.7% for UCCIS, 85.3% for UCEIS, 76.0% for FC, and 73.3% for MES.CONCLUSIONThe three endoscopic scores and FC may predict UC relapse during clinical remission. Among these scores, UCEISmay be the most useful in terms of ease of evaluation and accuracy.
文摘Dear Editor,We report a case of multiple evanescent white dot syndrome(MEWDS)relapse following mRNA corona virus disease 2019(COVID-19)vaccination.MEWDS is a choroidal inflammatory disease belonging to the group of“white dot syndromes”group,with an excellent prognosis[1].MEWDS is usually idiopathic,but there have been reports of MEWDS following viral infection or vaccination[1-2].
文摘BACKGROUND Colorectal cancer(CRC)is a common life-threatening disease that often requires surgical intervention,such as laparoscopic radical resection.However,despite successful surgeries,some patients experience disease relapse.Identifying the risk factors for CRC relapse can help guide clinical interventions and improve patient outcomes.AIM To determine the risk factors that may lead to CRC relapse after laparoscopic radical resection.METHODS We performed a retrospective analysis using the baseline data of 140 patients with CRC admitted to our hospital between January 2018 and January 2020.All included participants were followed up until death or for 3 years.The baseline data and laboratory indicators were compared between the patients who experienced relapse and those who did not experienced relapse.RESULTS Among the 140 patients with CRC,30 experienced relapse within 3 years after laparoscopic radical resection and 110 did not experience relapse.The relapse group had a higher frequency of rectal tumors with low differentiation and lymphatic vessel invasion than that of the non-relapse group.The expression of serum markers and the prognostic nutritional index were lower,whereas the neutrophil-to-lymphocyte ratio,expression of cytokeratin 19 fragment antigen 21-1,vascular endothelial growth factor,and Chitinase-3-like protein 1 were significantly higher in the relapse group than those in the non-relapse group.The groups did not differ significantly based on other parameters.Logistic regression analysis revealed that all the above significantly altered factors were independent risk factors for CRC relapse.CONCLUSION We identified multiple risk factors for CRC relapse following surgery,which can be considered for the clinical monitoring of patients to reduce disease recurrence and improve patient survival.
文摘Background: Neglected clubfoot in this series is defined as untreated equino-cavo-adducto-varus in older children or adults. Relapsed clubfoot is the residual deformity that remains after single or multiple surgical interventions. Severely neglected clubfoot rarely exists today in developed countries, except in some emigrants from low- and middle-income countries. Acute surgical management with corrective mid-foot osteotomy and elongation of the Achilles tendon has an excellent functional outcome. Objective: To assess the functional outcome of acute correction of neglected Talipes-quinoa-varus deformity in adults. Methods: This is a cross-sectional, hospital–based multi-centric study. Forty patients were included in this study. Midfoot osteotomy and elongation of the Achilles tendon were performed on all patients. Data was collected using a questionnaire and the functional outcome has been assessed using the American Orthopedic Foot and Ankle Society Score (AOFAS). This score was measured before surgery and one year after surgery. Results: the mean age was 19.9 ± 4.7 years. Males were 25 (62.5%) and females were 15 (37.5%). The mean preoperative AOFAS score was 37.7 ± 7.1 (poor). This score improved to 80.7 ± 13.7 (good to excellent), two years after surgery. However, this indicates a significant change in the functional outcome after the operation (p value Conclusion: acute correction of neglected and relapsed TEV with elongation of the Achilles tendon and single midfoot osteotomy has excellent functional outcome as assessed by AOFAS Score. The satisfaction with this procedure is impressive. The younger age population showed better outcomes with this procedure.

文摘Glioblastoma is acknowledged as the most aggressive cerebral tumor in adults.However,the efficacy of current standard therapy is seriously undermined by drug resistance and suppressive immune microenvironment.Ferroptosis is a recently discovered form of iron-dependent cell death that may have excellent prospect as chemosensitizer.The utilization of ferropotosis inducer Erastin could significantly mediate chemotherapy sensitization of Temozolomide and exert anti-tumor effects in glioblastoma.In this study,a combination of hydrogel-liposome nanoplatform encapsulatedwith Temozolomide and ferroptosis inducer Erastin was constructed.Theαvβ3 integrin-binding peptide cyclic RGD was utilized to modify codelivery system to achieve glioblastoma targeting strategy.As biocompatible drug reservoirs,cross-linked GelMA(gelatin methacrylamide)hydrogel and cRGD-coated liposome realized the sustained release of internal contents.In the modified intracranial tumor resection model,GelMA-liposome system achieved slow release of Temozolomide and Erastin in situ for more than 14 d.The results indicated that nanoplatform(T+E@LPs-cRGD+GelMA)improved glioblastoma sensitivity to chemotherapeutic temozolomide and exerted satisfactory anti-tumor effects.It was demonstrated that the induction of ferroptosis could be utilized as a therapeutic strategy to overcome drug resistance.Furthermore,transcriptome sequencing was conducted to reveal the underlying mechanism that the nanoplatform(T+E@LPs-cRGD+GelMA)implicated in.It is suggested that GelMA-liposome system participated in the immune response and immunomodulation of glioblastoma via interferon/PD-L1 pathway.Collectively,this study proposed a potential combinatory therapeutic strategy for glioblastoma treatment.
文摘BACKGROUND Extraskeletal osteosarcoma(ESOS)is a highly malignant osteosarcoma that occurs in extraskeletal tissues.It often affects the soft tissues of the limbs.ESOS is classified as primary or secondary.Here,we report a case of primary hepatic osteosarcoma in a 76-year-old male patient,which is very rare.CASE SUMMARY Here,we report a case of primary hepatic osteosarcoma in a 76-year-old male patient.The patient had a giant cystic-solid mass in the right hepatic lobe that was evident on ultrasound and computed tomography.Postoperative pathology and immunohistochemistry of the mass,which was surgically removed,suggested fibroblastic osteosarcoma.Hepatic osteosarcoma reoccurred 48 d after surgery,resulting in significant compression and narrowing of the hepatic segment of the inferior vena cava.Consequently,the patient underwent stent implantation in the inferior vena cava and transcatheter arterial chemoembolization.Unfortunately,the patient died of multiple organ failure postoperatively.CONCLUSION ESOS is a rare mesenchymal tumor with a short course and a high likelihood of metastasis and recurrence.The combination of surgical resection and chemotherapy may be the best treatment.

文摘Objective Preclinical evidence and clinical trials have suggested synergistic effects of epigenetic modifiers in combination with cytotoxic agents for the treatment of leukemia.However,their efficacy in patients with relapsed/refractory acute myeloid leukemia(R/R AML)remains unclear.Methods Clinical data of R/R AML patients who received a CDCAG regimen(chidamide,decitabine,cytarabine,aclarubicin,and granulocyte colony-stimulating factor)from July 1,2018 to October 31,2021 at our center were retrospectively assessed,and the safety and efficacy of the CDCAG regimen were evaluated.Patients were followed up until November 30,2021,with a median follow-up of 21.6 months(95%CI:10.0–33.2 months).Results A total of 67 patients were enrolled.Two patients died within 3 weeks after the initiation,and therefore only 65 patients underwent the assement for clinical response and survival.It was found that 56.9%patients achieved complete remission with a median overall survival(OS)of 9.6 months.The median OS of responders was 25.9 months,while that of non-responders was 5.0 months(P<0.0001).Patients with gene mutations had a superior overall response rate(ORR)(80.4%vs.45.5%,P=0.043)compared to those without gene mutations.The presence of DNA methyltransferase 3 A(DNMT3A),ten-eleven translocation-2(TET2),and isocitrate dehydrogenase 1/2(IDH1/2)mutations did not affect the response rate(88.2%vs.68.9%,P=0.220)and reflected a better OS(not attained vs.9.0 months,P=0.05).The most common non-hematologic adverse events were pulmonary infection(73.1%),followed by febrile neutropenia(23.9%)and sepsis(19.4%).Conclusions The CDCAG regimen was effective and well-tolerated in R/R AML patients,increasing the potential for allogeneic hematopoietic stem cell transplantation.Moreover,patients with DNMT3A,TET2,and IDH1/2 mutations might benefit from this regimen.
文摘BACKGROUND Patients with proteinase 3-antineutrophil cytoplasmic antibody associated vasculitis(AAV)experience different manifestations at the initial onset and relapse.However,such cases of different initial and relapse manifestations have not been reported in myeloperoxidase(MPO)-AAV patients.CASE SUMMARY A 52-year-old woman was admitted to our hospital because of headache.Laboratory findings indicated nephrotic range proteinuria and microscopic hematuria,serum creatinine of 243μmol/L,anti-MPO antibody titer of>400 RU/mL,and positive perinuclearantineutrophil cytoplasmic antibody.Renal biopsy showed pauci-immune crescentic glomerulonephritis.The cerebrospinal fluid examination and brain magnetic resonance imaging did not show any abnormality.Therefore,MPO-AAV was diagnosed.Corticosteroids,plasmapheresis,and cyclophosphamide as induction therapy and mycophenolate mofetil(MMF)as maintenance therapy were administered.The patient’s headache disappeared;serum creatinine returned to normal;complete remission of microscopic hematuria and proteinuria was observed.Anti-MPO antibody titer reached normal limits after immunosuppressive treatment.Twenty-five months after stopping the immunosuppressive treatment,the patient relapsed with arthralgia,without neurological or renal involvement.The patient’s arthralgia improved after treatment with prednisone and MMF.CONCLUSION We have reported a rare case of MPO-AAV who initially presented with headache and kidney involvement.However,relapse presented with only arthralgia,which was completely different from the initial manifestations.This case suggests that AAV relapse should be highly suspected in MPO-AAV patients after remission,when clinical manifestations at relapse are different from those at onset.Prednisone and MMF may provide a good choice for refractory arthralgia during relapse in MPO-AAV patients.

文摘Cellular senescence is characterized by a generally irreversible cell cycle arrest and the secretion of bioactive factors known as the senescence-associated secretory phenotype(SASP).In an oncogenic context,senescence is considered a tumor suppressive mechanism as it prevents cell proliferation and inhibits the progression from pre-malignant to malignant disease.However,recent studies have demonstrated that senescent tumor cells,which could spontaneously exist within cancer tissues or arise in response to various cancer interventions(the so-called therapy-induced senescence,TIS),can acquire pro-tumorigenic properties and are capable of driving local and metastatic relapse.This highlights the complex and multifaceted nature of cellular senescence in cancer biology.Here,we summarize the current knowledge of the pathological function of therapy-induced senescent tumor cells and discuss possible mechanisms by which tumor cell senescence contributes to cancer relapse.We also discuss implications for future studies toward targeting these less appreciated cells.

文摘BACKGROUND Eosinophilic gastroenteritis(EGE)is a chronic recurrent disease with abnormal eosinophilic infiltration in the gastrointestinal tract.Glucocorticoids remain the most common treatment method.However,disease relapse and glucocorticoid dependence remain notable problems.To date,few studies have illuminated the prognosis of EGE and risk factors for disease relapse.AIM To describe the clinical characteristics of EGE and possible predictive factors for disease relapse based on long-term follow-up.METHODS This was a retrospective cohort study of 55 patients diagnosed with EGE admitted to one medical center between 2013 and 2022.Clinical records were collected and analyzed.Kaplan-Meier curves and log-rank tests were conducted to reveal the risk factors for long-term relapse-free survival(RFS).RESULTS EGE showed a median onset age of 38 years and a slight female predominance(56.4%).The main clinical symptoms were abdominal pain(89.1%),diarrhea(61.8%),nausea(52.7%),distension(49.1%)and vomiting(47.3%).Forty-three(78.2%)patients received glucocorticoid treatment,and compared with patients without glucocorticoid treatments,they were more likely to have elevated serum immunoglobin E(IgE)(86.8%vs 50.0%,P=0.022)and descending duodenal involvement(62.8%vs 27.3%,P=0.046)at diagnosis.With a median follow-up of 67 mo,all patients survived,and 56.4%had at least one relapse.Six variables at baseline might have been associated with the overall RFS rate,including age at diagnosis<40 years[hazard ratio(HR)2.0408,95%confidence interval(CI):1.0082–4.1312,P=0.044],body mass index(BMI)>24 kg/m^(2)(HR 0.3922,95%CI:0.1916-0.8027,P=0.014),disease duration from symptom onset to diagnosis>3.5 mo(HR 2.4725,95%CI:1.220-5.0110,P=0.011),vomiting(HR 3.1259,95%CI:1.5246-6.4093,P=0.001),total serum IgE>300 KU/L at diagnosis(HR 0.2773,95%CI:0.1204-0.6384,P=0.022)and glucocorticoid treatment(HR 6.1434,95%CI:2.8446-13.2676,P=0.003).CONCLUSION In patients with EGE,younger onset age,longer disease course,vomiting and glucocorticoid treatment were risk factors for disease relapse,whereas higher BMI and total IgE level at baseline were protective.
文摘Autoimmune pancreatitis(AIP)is an autoimmune subtype of chronic pancreatitis resulting from the aberrant immune response against the pancreas,leading to inflammation and fibrosis.Although AIP is rare,its incidence is increasing and is often misdiagnosed as other pancreatic diseases.AIP is commonly classified into two types.Type 1 AIP(AIP-1)is typically associated with elevated serum immunoglobulin G4(IgG4)levels and systemic manifestations,while type 2 AIP is typically a more localized form of the disease,and may coexist with other autoimmune disorders,especially inflammatory bowel diseases.Additionally,there is emerging recognition of a third type(type 3 AIP),which refers to immunotherapy-triggered AIP,although this classification is still gaining acceptance in medical literature.The clinical manifestations of AIP mainly include painless jaundice and weight loss.Elevated serum IgG4 levels are particularly characteristic of AIP-1.Diagnosis relies on a combination of clinical,laboratory,radiological,and histological findings,given the similarity of AIP symptoms to other pancreatic disorders.The mainstay of treatment for AIP is steroid therapy,which is effective in most cases.Severe cases might require additional imm-unosuppressive agents.This review aims to summarize the current knowledge of AIP,encompassing its epidemiology,etiology,clinical presentation,diagnosis,and treatment options.We also address the challenges and controversies in diagnosing and treating AIP,such as distinguishing it from pancreatic cancer and managing long-term treatment,highlighting the need for increased awareness and knowledge of this complex disease.
文摘The first-line treatment for autoimmune hepatitis involves the use of prednisone or prednisolone either as monotherapy or in combination with azathioprine(AZA).Budesonide has shown promise in inducing a complete biochemical response(CBR)with fewer adverse effects and is considered an optional first-line treatment,particularly for patients without cirrhosis;however,it is worth noting that the design of that study favored budesonide.A recent real-life study revealed higher CBR rates with prednisone when equivalent initial doses were administered.Current guidelines recommend mycophenolate mofetil(MMF)for patients who are intolerant to AZA.It is important to mention that the evidence supporting this recommendation is weak,primarily consisting of case series.Nevertheless,MMF has demonstrated superiority to AZA in the context of renal transplant.Recent comparative studies have shown higher CBR rates,lower therapeutic failure rates,and reduced intolerance in the MMF group.These findings may influence future guidelines,potentially leading to a significant modification in the first-line treatment of autoimmune hepatitis.Until recently,the only alternative to corticosteroids was lifelong maintenance treatment with AZA,which comes with notable risks,such as skin cancer and lymphoma.Prospective trials are essential for a more comprehensive assessment of treatment suspension strategies,whether relying on histological criteria,strict biochemical criteria,or a combination of both.Single-center studies using chloroquine diphosphate have shown promising results in significantly reducing relapse rates compared to placebo.However,these interesting findings have yet to be replicated by other research groups.Additionally,second-line drugs,such as tacrolimus,rituximab,and infliximab,should be subjected to controlled trials for further evaluation.
文摘BACKGROUND Hemophagocytic lymphohistiocytosis(HLH)is a rare,life-threatening disorder caused by abnormal histiocytes and T cell activation.In adults,it is predominantly associated with infections,cancers,and autoimmune diseases.Relapsing polychondritis(RP),another rare disease,is diagnosed based on symptoms without specific tests,featuring cartilage inflammation characterized by swelling,redness,and pain,rarely inducing HLH.CASE SUMMARY A 74-year-old woman visited the emergency room with a fever of 38.6℃.Blood tests,cultures,and imaging were performed to evaluate fever.Results showed increased fluorescent antinuclear antibody levels and mild cytopenia,with no other specific findings.Imaging revealed lymph node enlargement was observed;however,biopsy results were inconclusive.Upon re-evaluation of the physical exam,inflammatory signs suggestive of RP were observed in the ears and nose,prompting a tissue biopsy for confirmation.Simultaneously,persistent fever accompanied by cytopenia prompted a bone marrow examination,revealing hemophagocytic cells.After finding no significant results in blood culture,viral markers,and tissue examination of enlarged lymph nodes,HLH was diagnosed by RP.Treatment involved methylprednisolone followed by azathioprine.After two months,bone marrow examination confirmed resolution of hemophagocytosis,with normalization of hyperferritinemia and pancytopenia.CONCLUSION Thorough physical examination enabled diagnosis and treatment of HLH trig gered by RP in patients presenting with fever of unknown origin.
