The patient, an 11-year-old girl, was admitted with recurrent fever for 20 days, worsening with abdominal distension for 7 days. Upon admission, she presented with recurrent fever, lymphadenopathy, hepatosplenomegaly, polyserositis, and multiple organ dysfunction. Lymph node pathology and clinical manifestations confirmed the diagnosis of idiopathic multicentric Castleman disease-TAFRO syndrome. Treatment with siltuximab combined with glucocorticoids was initiated, followed by maintenance therapy with tocilizumab. The patient is currently in complete clinical remission. Therefore, once a child is diagnosed with idiopathic multicentric Castleman disease -TAFRO syndrome, early use of siltuximab should be considered for rapid disease control, followed by tocilizumab for maintenance therapy.

A 10-year-old girl was admitted with a 38-hour history of widespread subcutaneous petechiae and hematuria and a 6-hour history of jaundice and oliguria. Physical examination revealed widespread subcutaneous petechiae and jaundice of the skin and sclera. Laboratory tests showed anemia, thrombocytopenia, acute kidney injury, and markedly elevated lactate dehydrogenase. Thrombotic microangiopathy was initially diagnosed, with a high suspicion of atypical hemolytic uremic syndrome (aHUS). Eculizumab was initiated within 9 hours of admission (within 48 hours of onset). After the first infusion, hemolysis rapidly ceased, and the platelet count and renal function gradually returned to normal. Whole-exome sequencing identified homozygous deletions of CFHR1 exon 2 and CFHR4 exon 1. aHUS typically has abrupt onset and rapid progression. Clinicians should maintain high suspicion for aHUS when the triad of thrombocytopenia, microangiopathic hemolytic anemia, and acute kidney injury is present. Ultra-early eculizumab (within 48 hours of onset) rapidly blocks complement-mediated thrombotic microangiopathy, reverses organ injury, and improves long-term prognosis. Additionally, complement-related genetic testing is important for etiological clarification and individualized determination of eculizumab treatment duration.

OBJECTIVE: To observe the clinical effect of plasma exchange and tocilizumab in treatment of patients with severe coronavirus disease 2019 (COVID-19). METHODS: Six patients with severe COVID-19 admitted in First Affiliated Hospital of Bengbu Medical College from January 25 to February 25, 2020. Three patients were treated with plasma exchange and three patients were treated with tocilizumab. The effect on excessive inflammatory reaction of plasma exchange and tocilizumab was observed. RESULTS: The C-reactive protein (CRP) and IL-6 levels were significantly decreased and the lymphocyte and prothrombin time were improved in 3 patients after treatment with plasma exchange; while inflammation level was not significantly decreased, and lymphocyte and prothrombin time did not improve in 3 patients treated with tocilizumab. CONCLUSIONS For severe COVID-19 patients with strong inflammatory reaction, plasma exchange may be preferred.

Benralizumab is a monoclonal antibody that targets interleukin-5 receptor α to deplete blood eosinophils and improve the clinical outcomes of allergic asthma. We conducted a meta-analysis to evaluate the safety and efficacy of different doses of benralizumab in patients with eosinophilic asthma. All randomized controlled trials involving benralizumab treatment for patients with eosinophilic asthma, which were searched in PubMed, Embase, and the Cochrane Library published until January 2017, as well as the rate of asthmatic exacerbation, pulmonary functionality, asthma control, quality of life scores, and adverse events were included. Randomized-effect models were used in the meta-analysis to calculate the pooled mean difference, relative risks, and 95% confidence intervals. Five studies involving 1951 patients were identified. Compared with the placebo, benralizumab treatment demonstrated significant improvements in the forced expiratory volume in 1 s (FEV1), Asthma Quality of Life Questionnaire scores, decreased asthmatic exacerbation and Asthma Control Questionnaire-6 (ACQ-6) scores. Benralizumab treatment was also not associated with increased adverse events. These findings indicated that benralizumab can be safely used to improve FEV1, enhance patient symptom control and quality of life, and reduce the risk of exacerbations and ACQ-6 scores in patients with eosinophilic asthma. Furthermore, our meta-analysis showed that benralizumab with 30 mg (every eight weeks) dosage can improve the health-related quality of life and appear to be more effective than 30 mg (every four weeks) dosage. Overall, data indicated that the optimal dosing regimen for benralizumab was possibly 30 mg (every eight weeks).

The NCCN has recently released its 2017 version 1.0 guideline for colorectal cancer. There are several updates from this new version guideline which are believed to change the current clinical practice. Update one, low-dose aspirin is recommended for patients with colorectal cancer after colectomy for secondary chemoprevention. Update two, biological agents are removed from the neoadjuvant treatment regimen for resectable metastatic colorectal cancer (mCRC). This update is based on lack of evidence to support benefits of biological agents including bevacizumab and cetuximab in the neoadjuvant setting. Both technical criteria and prognostic information should be considered for decision-making. Currently biological agents may not be excluded from the neoadjuvant setting for patients with resectable but poor prognostic disease. Update three, panitumumab and cetuximab combination therapy is only recommended for left-sided tumors in the first line therapy. The location of the primary tumor can be both prognostic and predictive in response to EGFR inhibitors in metastatic colorectal cancer. Cetuximab and panitumumab confer little benefit to patients with metastatic colorectal cancer in the primary tumor originated on the right side. On the other hand, EGFR inhibitors provide significant benefit compared with bevacizumab-containing therapy or chemotherapy alone for patients with left primary tumor. Update four, PD-1 immune checkpoint inhibitors including pembrolizumab or nivolumab are recommended as treatment options in patients with metastatic deficient mismatch repair (dMMR) colorectal cancer in second- or third-line therapy. dMMR tumors contain thousands of mutations, which can encode mutant proteins with the potential to be recognized and targeted by the immune system. It has therefore been hypothesized that dMMR tumors may be sensitive to PD-1 inhibitors.

Ulcerative colitis is a chronic inflammatory condition of the colon, characterized by diffuse mucosal inflammation and blood-mixed diarrhea. The main treatment has been 5-aminosalicylic acid, steroid, thiopurine, and anti-tumor necrosis factor alpha (TNF-alpha) antibodies including infliximab, adalimumab, and golimumab. Golimumab, a new anti-TNF-alpha agent has been recently approved for patients with moderate to severe ulcerative colitis. Its efficacy and safety has been demonstrated in line with infliximab and adalimumab in preclinical and clinical studies. This review will focus on golimumab therapy in ulcerative colitis.

PURPOSE: To compare pain scores of patients during intravitreal 27-gauge bevacizumab and 30-gauge ranibizumab injection procedures. METHODS: Seventy eyes of 70 patients who had not previously undergone intravitreal anti-vascular endothelial growth factor therapy were included in this study. Thirty-five patients received ranibizumab and 35 patients received bevacizumab. The diagnoses of the patients were: 27 age related macular degeneration, 15 diabetic macular edema, 9 diabetic vitreous hemorrhage, 6 central retinal vein occlusion, 11 branch retinal vein occlusion and 2 central serous chorioretinopathy. Bevacizumab (1.25 mg/0.05 mL) was injected into the vitreous cavity using a 27-gauge needle, and ranibizumab (0.5 mg/0.05 mL) was injected with 30-gauge needle. Patients were asked just after the injection to rate their perceived pain during the injection using the visual analogue scale (VAS) of 0 (no pain) to 10 (unbearable/worst pain). The average of these scores was used as the primary outcome. RESULTS: The VAS pain scores in the ranibizumab and bevacizumab groups were 1.06 +/- 0.91 (range, 0 to 3) and 1.94 +/- 1.55 (range, 0 to 7), respectively, a significant difference (p = 0.005). Patients <65 and > or =65 years of age in both the ranibizumab and bevacizumab groups were then compared. For patients <65, there was a significant difference in the average VAS pain scores between groups (p = 0.003). However, for patients > or =65 years, there was not a significant difference in the average VAS pain scores between groups (p = 0.238). Female and male patients in both ranibizumab and bevacizumab groups were also compared. For female patients, there was a significant difference in the average VAS pain scores between groups (p = 0.016), although not for male patients (p = 0.078). CONCLUSIONS: Thirty-gauge intravitreal injection is more comfortable than 27-gauge injection. Injection of bevacizumab with 30-gauge needle syringes may be more tolerable for patients.

BACKGROUNDPathological myopia (PM) is the leading cause for choroidal neovascularization (CNV) in people below 50 years of age, the anti-vascular endothlial growth factor (VEGF) medicine is now available to treat CNV secondary to PM. This study aimed to observe the efficacy of intravitreal ranibizumab for PM associated with subfoveal or juxtafoveal CNV in Chinese patients.

METHODSFifty-four eyes of 52 consecutive patients were included, they treated with intravitreal ranibizumab 0.5 mg for PM associated with CNV. The best corrected visual acuity (BCVA) of Snellen chart, letters of ETDRS chart, retinal thickness, leakage of CNV lesion, and complications with surgery were analyzed pre- and post-treatment. Eligibility criteria included diopter ≥-8.0 D or eye axis ≥ 28 mm with fundus changes of PM (lacquer crack, optic disc atrophy, chorioretinal atrophy, posterior scleral staphyloma); CNV secondary to PM; subfoveal or juxtafoveal CNV.

RESULTSFor 54 affected eyes of 52 consecutive patients, the average BCVA of Snellen chart and letters of ETDRS chart were 0.29 and 30.4, respectively; fundus fluorescein angiography (FFA)/indocyanine green angiography (ICGA) showed CNV leakage, and average retinal thickness on optical coherence tomography (OCT) was 267.2 µm before treatment. Injections of ranibizumab ranged from 1 to 4 (mean 2.2). Follow-up time varied from 12 to 36 months (mean 31.9 months). At the last visit, the BCVA of Snellen chart was increased by three lines (mean 0.65) (P < 0.01); the letters of ETDRS chart were increased to 17.0 letters (mean 47.4, P < 0.01); the visual acuity increased more than 15 letters in 30 eyes (55.5%), decreased in 1 eye (1.9%); the retinal thickness on OCT images was decreased by 17.0 µm (mean 250.2 µm) (P = 0.082); no active leakage from the CNV lesion occurred in 18 eyes (33.3%), reduced leakage in 30 eyes (55.6%), and no change in 6 eyes (11.1%) as shown by FFA/ICGA. Increased retinoschisis was observed in one eye after the second injection.

CONCLUSIONSIntravitreal ranibizumab for neovascular PM was well tolerated in Chinese patients, with functional and anatomic improvements in a short-term study, while a long-term study is still needed.
