Recurrence rate of oral melanotic macule treated with Q-switched alexandrite laser versus surgical excision: a retrospective cohort study / 口腔疾病防治

Objective@#To compare the recurrence rates between 755 nm Q-switched alexandrite laser (QSAL) treatment and surgical excision of oral melanotic macules (OMM).@*Methods@#This study was reviewed and approved by the Ethics Committee, and informed consent was obtained from the patients. A retrospective cohort study was designed to collect demographic and clinical characteristics and follow-up data from patients with OMM. Patients who received QSAL or surgical excision in the Department of Oral Medicine, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine from January 2019 to August 2021 were included. The one-year recurrence rate was investigated as the primary outcome. Long-term adverse reaction rates were investigated as safety indicators. Kaplan-Meier analyses were performed to analyze the recurrence-free rates between the groups.@*Results@#A total of 57 patients were enrolled in this study. 16 patients underwent surgical excision, and 41 underwent QSAL. The baseline demographic and clinical characteristics between the groups were not significantly different. No recurrence (0%) of OMM was observed in the surgical excision group, while in the QSAL group, the macule recurred in 12 patients (29.27%). The average duration of recurrence was 6.08 months after treatment. Recurrence was not found to be associated with smoking (P = 1.000), gastrointestinal polyps (P = 1.000), longitudinal melanonychia (P = 0.187), family history (P = 0.552), treatment sessions (P = 0.567) or multiple macule lesions (P = 0.497). Compared with treatment with surgical excision, the odds ratio of recurrence for treatment with QSAL was 4.41, with a 95% confidence interval of 1.27-15.24 (P = 0.020). In the surgical excision group, 3 patients (18.75%) reported depressions and scars on the lesion, while no long-term adverse reactions (0%) were reported in the QSAL group (P = 0.019).@*Conclusion@#Compared with surgical excision, the advantage of QSAL is the low long-term adverse reaction rate, while the disadvantage is the relatively high one-year recurrence rate. It is necessary to communicate the advantages and disadvantages of the two methods with OMM patients to assist in clinical decision-making.

Total Saponins in Paridis Rhizoma： A Review / 中国实验方剂学杂志

Paridis Rhizoma possesses the functions of clearing heat and detoxifying， alleviating swelling and relieving pain， cooling the liver and calming the convulsion. Saponins are the main active components of Paridis Rhizoma. Studies have shown that total saponins in Paridis Rhizoma have obvious inhibitory effect on solid tumors such as breast cancer， lung cancer， gastric cancer， and liver cancer and non-solid tumors such as leukemia. The saponins may exert the anti-tumor effects by inhibiting the proliferation， migration， and invasion of tumor cells， regulating cell cycle， inducing apoptotic and non-apoptotic death pathways， and regulating metabolism and tumor microenvironment. Furthermore， total saponins in Paridis Rhizoma showed anti-inflammatory， antioxidant， antimicrobial， hemostatic， and uterus-contracting activities. At the same time， they may induce apoptosis of normal cells， inflammation and oxidative stress， and metabolic disorders. In recent years， the reports of liver injury， reproductive injury， gastrointestinal injury， hemolysis， and other adverse reactions caused by total saponins in Paridis Rhizoma have been increasing. Pharmacokinetic studies have shown that there are significant differences in the metabolism of total saponins in Paridis Rhizoma administrated in different ways. Injection has a fast clearance rate， while oral administration may have hepatoenteric circulation. Meanwhile， due to the low solubility and activation of P-glycoprotein （P-gp） molecular pump， the prototype absorption， intestinal permeability， and recovery rate of total saponins in Paridis Rhizoma are poor， which affects the bioavailability. The bioavailability can be improved to some extent by preparing new dosage forms or new drug delivery systems with advanced technology. This paper reviews the pharmacological effect， pharmacokinetics， and adverse reactions of Rhizoma Paridis total saponins by searching the China National Knowledge Infrastructure （CNKI）， VIP， and Web of Science with ''Rhizoma Paridis total saponins'' as the keywords， hoping to provide references for the research， development， and clinical application of such components.

ABSTRACT Tuberculosis stands as one of humanity's oldest afflictions, intrinsically intertwined with social disparities. This formidable disease spares no age group and remains the prevailing cause of infection-induced mortality worldwide, particularly in developing nations. We present a case of a 56-year-old woman with diabetes who was diagnosed with Pulmonary Tuberculosis. After receiving antituberculosis drugs as part of her treatment, she experienced a range of systemic manifestations and suffered from severe ulcerative esophagitis. This adverse reaction led to uncontrollable gastrointestinal intolerance, tragically resulting in her untimely demise. The incident underscores the potential seriousness of adverse reactions that can arise from tuberculosis treatment medications.

A COVID-19 perspective of Vogt–Koyanagi–Harada disease

Vogt–Koyanagi–Harada (VKH) disease, a bilateral granulomatous panuveitis associated with multisystem involvement, is a T-cell-mediated autoimmune disorder in which cytotoxic T-cell target melanocytes in genetically susceptible individuals. Recently, there has been an increase in literature on the new onset of uveitis and reactivation of previously diagnosed cases of uveitis following Covid-19 vaccinations. It has been postulated that Covid-19 vaccines can lead to an immunomodulatory change resulting in an autoimmune phenomenon in the recipients. VKH following COVID-19 infection was reported in four patients and a total of 46 patients developing VKH or VKH-like disease following COVID-19 vaccinations. There are reports of four patients who had been recovering or recovered from VKH after receiving the first dosage of the vaccine and developed worsening of ocular inflammation after receiving the second dose of the vaccine.

Modern Research Progress of Polyphyllin Ⅰ： A Review / 中国实验方剂学杂志

Paridis Rhizoma， a traditional valuable Chinese herbal medicine， has the functions of clearing heat and removing toxin， relieving edema and pain， cooling liver and calming convulsion， which can be used to treat various diseases such as mumps， abscess， burn， bleeding， and tumor. It has been used in folk medicine for a long time and is the main raw material of various Chinese patent medicines such as Gongxuening Capsules and Yunnan Baiyao. Polyphyllin Ⅰ， an isospirostanol saponin and one of the main active components in Paridis Rhizoma， is distributed in the rhizome， pericarp， and leaves of Paris polyphylla. With high polarity， polyphyllin Ⅰ is mainly extracted by n-butanol extraction and macroporous adsorption resin chromatography， separated by silica gel column chromatography and preparative high performance liquid chromatography， and purified with the combination of methods. With anti-tumor， anti-inflammatory， antibacterial， and anti-virus effects， it is generally employed to treat liver cancer， lung cancer， gastric cancer and other cancers as well as arthritis， influenza， sore toxin， and bacterial infection. However， polyphyllin Ⅰ may cause stomach irritation， hemolysis， liver damage， kidney damage， heart damage， and other adverse reactions. Pharmacokinetic studies show that it has problems such as low bioavailability and poor intestinal absorption and permeability， which affect the clinical application of polyphyllin Ⅰ. This paper summarizes the research on the plant sources， extraction and separation methods， pharmacological effects， adverse reactions， and pharmacokinetics of polyphyllin Ⅰ in recent years， which is expected to provide a reference for the rational clinical application and other in-depth research work of polyphyllin Ⅰ.

Efficacy and safety of half-dose rituximab in the treatment of 23 cases with lupus nephritis / 中华内科杂志

The study aimed to analyze the efficacy and safety of rituximab in the treatment of 23 cases of lupus nephritis and explore the prospect of half-dose rituximab in lupus nephritis treatment. Twenty-three patients with lupus nephritis hospitalized in the Department of Rheumatology and Immunology at the First Medical Center of the PLA General Hospital from May 2013 to December 2021 were selected. Eighteen patients received rituximab 375 mg/m 2 on the first and 14th days, 5 patients received 500 mg of rituximab on the first and 14th days, and rituximab was used as needed 6 months later. Methylprednisolone (80-120 mg) was given together with rituximab. Afterward, 1 mg/kg prednisone was used for 4 weeks, which was progressively tapered to maintenance doses or discontinued. B lymphocyte level, renal function, 24-h urine protein level, and systemic lupus erythematosus (SLE) disease activity index 2000 (SLEDAI2K) score before and after treatment were recorded. The efficacy and adverse reactions were analyzed. The results showed that 11 patients suffered from renal insufficiency [creatinine (162.7±58.6) μmol/L ] at baseline, while the creatinine level of 9 patients returned to normal 12 months after the treatment [ (66.3±10.1)μmol/L ]. Normal renal function of the other 12 patients was maintained during treatment. After 12 months, the 24-h urine protein level decreased from 4.00 (2.00,6.80) g in the baseline period to 0.10 (0.08,0.40) g. SLEDAI2K score decreased from 22 (18,26) in the baseline period to 3 (0,6) 12 months after the treatment. The B lymphocyte level reached 0.00 (0.00,0.01)% at 3 months. Of 23 patients, 13 patients achieved complete remission, and 7 patients achieved partial remission after 6 months of rituximab treatment. Five patients experienced adverse reactions related to rituximab, including 1 case of transfusion reaction, 1 case of perioral herpes with pulmonary infection, and 3 cases of decreased IgG levels. Therefore, rituximab regimen used in this study can be an effective treatment strategy for lupus nephritis.

Correlation between acute intestinal toxicity and dose-volume parameters in patients with cervical cancer receiving postoperative adjuvant radiotherapy / 中华放射肿瘤学杂志

Objective:To identify dose-volume parameters to predict the incidence of acute intestinal toxicity in cervical cancer patients after postoperative adjuvant radiotherapy.Methods:Clinical data of 93 cervical cancer patients who underwent postoperative adjuvant intensity-modulated radiotherapy (IMRT) were retrospectively evaluated. The dose-volume parameters comprised the absolute volume of the bowel receiving 5-45 Gy (5 Gy interval) radiation dose and the total volume of the bowel. The acute radiation-induced intestinal toxicity was evaluated by Radiation Therapy Oncology Group (RTOG) criteria. The association between the irradiated bowel volume and acute intestinal toxicity was analyzed.Results:A total of 26 (28%) patients experienced grade ≥2 acute intestinal toxicity. A strong relationship between grade ≥2 acute intestinal toxicity and the irradiated small bowel volume was observed at the total volume of small bowel, small bowel V 5 Gy, V 10 Gy and V 15 Gy (all P<0.05). Small bowel V 10 Gy ( HR=1.028, 95% CI, 0.993-1.062, P=0.029) and small bowel ?V 15 Gy( HR=0.991, 95% CI, 0.969-1.013, P=0.034)were the independent risk factors for evident acute intestinal toxicity. Conclusion:Dose-volume parameters of the small bowel can be used as predictors for the occurrence of grade ≥2 acute intestinal toxicity in cervical cancer patients undergoing postoperative adjuvant radiotherapy.

Effect of continuous renal replacement therapy on plasma concentration, clinical efficacy and safety of colistin sulfate / 中华危重病急救医学

Objective:To investigate the effects of continuous renal replacement therapy (CRRT) on plasma concentration, clinical efficacy and safety of colistin sulfate.Methods:Clinical data of patients received with colistin sulfate were retrospectively analyzed from our group's previous clinical registration study, which was a prospective, multicenter observation study on the efficacy and pharmacokinetic characteristics of colistin sulfate in patients with severe infection in intensive care unit (ICU). According to whether patients received blood purification treatment, they were divided into CRRT group and non-CRRT group. Baseline data (gender, age, whether complicated with diabetes, chronic nervous system disease, etc), general data (infection of pathogens and sites, steady-state trough concentration, steady-state peak concentration, clinical efficacy, 28-day all-cause mortality, etc) and adverse event (renal injury, nervous system, skin pigmentation, etc) were collected from the two groups.Results:A total of 90 patients were enrolled, including 22 patients in the CRRT group and 68 patients in the non-CRRT group. ① There was no significant difference in gender, age, basic diseases, liver function, infection of pathogens and sites, colistin sulfate dose between the two groups. Compared with the non-CRRT group, the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and sequential organ failure assessment (SOFA) were higher in the CRRT group [APACHE Ⅱ: 21.77±8.26 vs. 18.01±6.34, P < 0.05; SOFA: 8.5 (7.8, 11.0) vs. 6.0 (4.0, 9.0), P < 0.01], serum creatinine level was higher [μmol/L: 162.0 (119.5, 210.5) vs. 72.0 (52.0, 117.0), P < 0.01]. ② Plasma concentration: there was no significant difference in steady-state trough concentration between CRRT group and non-CRRT group (mg/L: 0.58±0.30 vs. 0.64±0.25, P = 0.328), nor was there significant difference in steady-state peak concentration (mg/L: 1.02±0.37 vs. 1.18±0.45, P = 0.133). ③ Clinical efficacy: there was no significant difference in clinical response rate between CRRT group and non-CRRT group [68.2% (15/22) vs. 80.9% (55/68), P = 0.213]. ④ Safety: acute kidney injury occurred in 2 patients (2.9%) in the non-CRRT group. No obvious neurological symptoms and skin pigmentation were found in the two groups. Conclusions:CRRT had little effect on the elimination of colistin sulfate. Routine blood concentration monitoring (TDM) is warranted in patients received with CRRT.

Disease-modifying therapy for spinal muscular atrophy / 中华实用儿科临床杂志

Spinal muscular atrophy (SMA) was a severe inherited neuromuscular disease caused by the deficiency of the survival motor neuron (SMN) protein encoded by SMN1 gene with pathogenic variants.According to the age of onset and maximal achievement of motor function, SMA was classified into 4 subtypes.The most common and severe subtype was SMA type 1.During the natural course, most of patients with SMA type 1 die of respiratory failure within 2 years of age if not treated.Patients with other subtypes have progressive muscle weakness and atrophy at varying degrees.Before the emergence of disease-modifying therapy, a multidisciplinary management, including physical therapy, respiratory and nutritional support, has been the only approach to delay the disease progression and enhance the survival rate of SMA.However, motor milestone progress is unable to achieve by SMA patients, because the lack of SMN protein has not been solved.In the past 5 years, 3 drugs have been approved for the treatment of SMA.Clinical trials and a growing number of real-world study data have shown that medications of disease-modifying agents contribute to effectively improve motor function in SMA patients with different subtypes, and promote the motor milestone progress in some patients, which significantly reduce the mortality.However, treatment response of disease-modifying agents to SMA varies with the subtypes of SMA, individualized conditions and courses of disease.Therefore, it is particularly important to choose an optimal treatment to ensure the quality of life of patients.This review focuses on recent advances and emerging challenges in the treatment of SMA.

Progress on adverse reactions and prevention and treatment of ketogenic diet therapy / 国际儿科学杂志

Ketogenic diet(KD)is a formulation diet with a high proportion of fat, low proportion of carbohydrates, appropriate protein and other nutrients, which has been used for centuries in the treatment of refractory epilepsy.In recent years, KD has been shown to be effective in the treatment of other diseases, such as amyotrophic lateral sclerosis, traumatic brain injury, diabetes, obesity, etc.Although KD has a positive effect on the treatment of a variety of diseases, the short-term and long-term adverse reactions caused by the imbalance of its nutritional structure should not be ignored.This article reviews the adverse reactions of KD in the treatment of children with refractory epilepsy and the corresponding prevention and treatment measures, to guide safe and efficient implementation of KD therapy in the clinic.

Analysis of heart rate variability during blood donation / 中国输血杂志

【Objective】 To observe the regulation of autonomic nerves in blood donors during blood donation by heart rate variability analysis and explore the possible mechanism of donation related vasovagal reaction. 【Methods】 Electrocardiogram (ECG) of 90 blood donors was monitored by Fontaine Ⅰlead during the whole process of blood donation, and the 5-min heart rate variation before, during and after blood donation was analyzed. 【Results】 During the whole process of blood donation, the sympathetic HRV index (LF nu) and the sympathetic and vagal balance ability index (LF/HF) increased, whereas the vagal nerve index (pNN50, RMSSD, HFnu) and heart rate variability index (SDNN, Total power) decreased. For baseline heart rate variability of different blood donors (first-time vs. repeated, male vs. female, 18-24 years old vs. ≥25 years old, <400 mL vs. 400 mL) before blood donation, the pNN50, RMSSD and Total power of 18-24 years old blood donors were higher, but other indicators showed no significant difference. There were differences in HRV indexes of different types of blood donors during blood donation compared with before blood donation. The decrease of pNN50 and HFnu and the increase of LF/HF were larger in experienced blood donors than in first-time blood donors. The decrease of RMSSD was larger in male blood donors than in female blood donors; the change of LF/HF was larger in blood donors aged≥25 years than in blood donors aged 18-24 years; other indicators had no significant difference. 【Conclusion】 Blood donation leads to reflex readjustment of the cardiac autonomic tone: the sympathetic nerve is excited while the vagal nerve is suppressed. The cardiac autonomic nerve function of first-time blood donors, female donors and low-age (18-24 years old) donors to blood donation stress is not fully regulated. Donation related vasovagal reaction may be related to the autonomic nerve regulation function of blood donors.

Exploration of the relationship between the storage time of leukodepleted red blood cell and transfusion adverse reactions / 中国输血杂志

【Objective】 To explore the relationship between the storage time of leukodepleted red blood cells and transfusion adverse reactions by analyzing the occurrence of transfusion adverse reactions of patients after leukodepleted red blood cells transfusion from four hospitals. 【Methods】 By using the electronic medical record management system, the collection and transfusion dates of leukodepleted red blood cells from four hospitals in Enshi Prefecture from 2018 to 2022, as well as the information on transfusion adverse reactions, were retrieved. 【Results】 From 2018 to 2022, a total of 697 61 bags of leukodepleted red blood cells were transfused in four hospitals, resulting in 166 cases of transfusion adverse reactions, among which 93 were allergic reactions, 63 were non hemolytic febrile reactions, and 10 were others, with a total incidence rate of transfusion adverse reactions at 0.24%. The average storage time of leukodepleted red blood cells with and without transfusion adverse reactions was (20.25±6.31) and (19.88±5.50) days, respectively. With a storage time of 7 days as the threshold, the incidence of transfusion adverse reactions was the lowest for a storage time of 15~21 days. The incidence of transfusion adverse reactions of leukodepleted red blood cells in two groups (with storage days ≤21 days and >21 days) was not statistically significant(P>0.05). 【Conclusion】 Allergic reactions were the main type of transfusion adverse reaction caused by leukodepleted red blood cells, and the incidence of transfusion adverse reactions decreased and then increased with the prolongation of the storage time of leukodepleted red blood cells. There was no significant difference in the incidence of transfusion adverse reactions with leukodepleted red blood cells stored for ≤ 21 days and >21 days.

Adverse events in platelet-rich plasma collection and countermeasures / 中国输血杂志

【Objective】 To explore the quality of platelet-rich plasma(PRP) and adverse events during PRP collection and the countermeasures, so as to provide reference for the development of PRP therapy. 【Methods】 A total of 412 patients who underwent PRP treatment from November 2020 to October 2022 were statistically analyzed in terms of the general data, PRP quality and adverse events during collection, and the countermeasures were formulated. 【Results】 PRP was collected from 409 patients with a volume of (48.391±6.262) mL, with platelet concentration at (1 125.548±366.036)×109/L. There were 33 adverse events occurred in 412 patients, with an incidence of 8.01% (33/412), among which 10 was regarding to collection and 23 were adverse reaction to blood donation. The reasons include mental factors, hyperlipidemia, hypovolemia, abnormal red blood cell morphology and venous puncture injury. 【Conclusion】 Countermeasures against the relative risk factors of adverse events during PRP collection, such as exclusion of hyperlipidemia, relieving mental stress, providing adequate communication and water to patients with low body weight, lowering the collection and transfusion flow rate to patients with poor vascular status and providing calcium gluconate to patients with low calcium response should be taken.

Sarcopenia Before Concurrent Chemoradiotherapy May Develop Severe Adverse Reactions in Patients with Esophageal Squamous Cell Carcinoma / 肿瘤防治研究

Objective To investigate whether sarcopenia before concurrent chemoradiotherapy is prone to grade≥3 acute adverse reactions (AAR) and shorten survival in patients with advanced esophageal squamous cell carcinoma (ESCC). Methods Data of advanced patients with pathologically diagnosed ESCC and CCRT (FP regimen) from August 2018 to July 2022 were reviewed retrospectively.Skeletal muscle mass and body composition were measured using pre-treatment CT images, and patients were divided into sarcopenia and non-sarcopenia groups.Grade≥3 AAR was diagnosed based on CTCAE5.0 and acute radiation injury criteria of the US RTOG.Risk factors for developing grade≥3 AAR were analyzed, and survival rates were calculated by Kaplan-Meier method. Results Among 132 patients with ESCC (87 in the sarcopenia group and 45 in the non-sarcopenia group), 23(17.4%) experienced grade≥3 AAR.In multivariate regression analysis, independent risk factors for grade ≥3 AAR included the following: sarcopenia (OR: 6.034, 95%CI: 1.206-30.190, P=0.029), decreased SMD (OR: 0.693, 95%CI: 0.492-0.976, P=0.036), decreased SMI (OR: 0.841, 95%CI: 0.721-0.982, P=0.028), and increased FMI (OR: 2.433, 95%CI: 1.194-4.958;P=0.014).The OS rates were 16.01 months (95%CI: 14.89-17.13) in the sarcopenia group and 19.27 months (95%CI: 14.45-24.09) in the non-sarcopenia group (χ2=5.326, P=0.021) as well as 14.86 months (95%CI: 11.30-18.42) for patients with grade≥3 AAR and 16.67 months (95%CI: 14.91-18.43) for patients with grade 0-2 AAR (χ2=5.47, P=0.019).Among patients with grade≥3 AAR, the OS rates were 12.13 months (95%CI: 10.15-14.11) in the sarcopenia group and 18.69 months (95%CI: 12.85-21.88) in the non-sarcopenia group (χ2=4.466, P=0.035). Conclusion Sarcopenia, decreased skeletal muscle density, and increased fat mass are important predictors of grade≥3 AAR.The OS of patients with sarcopenia and grade≥3 AAR may be reduced.

Efficacy of different enteral nutrition drugs for severe acute pancreatitis and their gastrointestinal tolerance / 中国药房

OBJECTIVE To compare the efficacy of different enteral nutrition （EN） drugs for severe acute pancreatitis （SAP） and their gastrointestinal tolerance. METHODS A total of 118 SAP patients admitted to the Pancreatic Center of Jiangsu Provincial People’s Hospital from January 1， 2022 to June 30， 2023 were collected and divided into short-peptide EN drugs （SP） group （41 cases）， dietary fiber-free intact protein EN drugs （TP-MCT） group （40 cases） and dietary fiber-containing intact protein EN drugs （TPF-DM） group （37 cases） according to the types of EN. All three groups of patients were given continuous pumps of EN drugs via nasal feeding for 24 hours， with a target energy dose of 25-30 kcal/kg. The blood nutritional indexes [albumin （ALB）， total protein （TP）， hemoglobin （Hb）， globulin （GLB）]， inflammation indexes [white blood cells （WBC）， percentage of neutrophils （N%）， procalcitonin （PCT）， C-reactive protein （CRP）， interleukin-6 （IL-6）]， clinical outcomes indexes [time of stay in the intensive care unit （ICU）， length of hospital stay， duration of resuming oral diet， the rate of cases without improvement， mortality rate] and the occurrence of gastrointestinal tolerance were collected from 3 groups before medication and 7 d after medication. RESULTS After treatment， ALB and TP in 3 groups were significantly higher than before treatment （P＜0.05）； CRP and N% of 3 groups， PCT of TP-MCT group and IL-6 of SP group were significantly lower than corresponding group before medication （P＜ 0.05）； PCT of TP-MCT group and IL-6 of SP group were significantly lower than those of other two groups at corresponding period （P＜0.05）. There were no statistical significances in ALB， TP， CRP or N% among the three groups after medication， and in Hb， GLB or WBC among the three groups before and after treatment （P＞0.05）. There was no significant difference in clinical outcome indexes among 3 groups （P＞0.05）. The incidence of gastrointestinal adverse reactions in the TP-MCT group was the lowest （32.50%）， and significantly lower than those in the SP group （46.34%） and TPF-DM group （48.65%） （P＜0.05）. CONCLUSIONS Different EN preparations can improve the nutritional status and reduce the inflammatory response in SAP patients to different extents， among which SP and TP-MCT are more effective， and TP-MCT shows the better gastrointestinal tolerance.

Safety of omalizumab in the treatment of children with allergic diseases / 中国药房

OBJECTIVE To analyze the safety of omalizumab in the treatment of allergic diseases in children. METHODS Clinical data of children with allergic diseases who were prescribed omalizumab therapy were collected from our hospital during February 2019 to July 2023， including the children’s basic conditions， allergen test results， serum levels of total immunoglobulin E （IgE）， omalizumab application and the occurrence of adverse events. The information on telephone follow-up was collected among the children who had completed treatment 12th month after drug withdrawal. At the same time， the causal relationship between adverse events and omalizumab was also evaluated by using the Naranjo assessment scale. RESULTS A total of 30 children were enrolled and received subcutaneous injections of omalizumab 245 times， accumulating 473 times. Four children suffered from four times of immediate-type hypersensitivity reactions （degree Ⅰ and Ⅱ every two times）， with an incidence of 13.3%； among them， two cases occurred after the first injection， one after the third injection， and one after the fifth injection； the results of the causality evaluation showed that two cases were “very likely” and two cases were “likely”. The telephone follow-up of 21 children showed that the children were in good health and there were no adverse events， such as malignant tumors， worm infections， serum disease- like reactions and arterial thromboembolism. CONCLUSIONS Omalizumab in children with allergic diseases is of good safety with a low incidence of adverse reactions， which are mainly mild immediate-type hypersensitivity reactions with a high long-term safety profile.
