A Severe Case of Reye's Syndrome with Multiorgan Dysfunction after Epstein-Barr Virus Infection

A 20-month-old male infant with multiorgan dysfunction after Epstein-Barr virus (EBV) infection developed Reye's syndrome. He also suffered from acute liver failure, life-threatening cerebral edema, severe disseminated intravascular coagulation (DIC), and myocardial involvement. EBV infection aggravated the progress of Reye's syndrome, leading to death despite full supportive and symptomatic therapy. This critical case suggested that pediatricians should pay attention to multiorgan involvement of severe EBV infection.     

Thyroid dysfunction during PD-1 inhibitor treatment in patients with cancer: Incidence and association with progression-free survival

The use of programmed cell death-1 (PD-1) inhibitors has recently been approved in China. As a consequence, the identification of relevant prognostic markers that can assess the efficacy of these compounds is required. Therefore, the present study aimed to explore the incidence of thyroid dysfunction and its ability to predict progression-free survival (PFS) in Chinese patients with cancer who received PD-1 inhibitor treatment. Data from 72 patients with cancer who received treatment with PD-1 inhibitors alone or in combination with chemotherapy or targeted drugs were analyzed. Moreover, the expression levels of free triiodothyronine, thyroxine, and thyrotropin during treatment were assessed to evaluate thyroid dysfunction. A total of 26 (36.1%) patients who had received PD-1 inhibitors developed thyroid dysfunction. Specifically, the incidence of thyroid dysfunction was 35.6% in patients with lung cancer, 25.0% in patients with malignant melanoma, and 46.7% in patients with other types of cancer. In addition, the median PFS was 7.0 (95% confidence interval, 4.9-9.1) months, whereas the 1- and 2-year PFS rates were 35.1 and 26.2%, respectively. Generally, patients with thyroid dysfunction exhibited longer PFS compared with those without thyroid dysfunction (P=0.001). Subgroup analyses were subsequently performed, which demonstrated that thyroid dysfunction was associated with longer PFS in patients with malignant melanoma (P=0.039) and other types of cancer (P=0.002), but not in those with lung cancer (P=0.083). These findings were noted in patients who received PD-1 inhibitor monotherapy (P=0.003), but not PD-1 inhibitor plus chemotherapy (P=0.172) or PD-1 inhibitor plus targeted therapy (P=0.582). Finally, thyroid dysfunction [P=0.001; hazard ratio (HR)=0.260] and PD-1 inhibitor monotherapy (P=0.015; HR=2.231) were identified as independent factors that could predict PFS. In conclusion, the present study demonstrated that thyroid dysfunction during PD-1 inhibitor treatment could be used as a potential marker for the prognosis of favorable PFS in patients with cancer.     

Tear film lipid layer thickness measurement from Ocular Surface Analyzer as a marker to monitor treatment of meibomian gland dysfunction in a study comparing physiological detergent-free eyelid wipes with conventional therapy: A randomized trial

Purpose:To compare the efficacy of physiological, non-detergent eyelid wipes with conventional lid hygiene in patients with meibomian gland dysfunction (MGD).Methods:Fifty participants with MGD were recruited and randomized into two groups. Participants in group I used Evolve Pure™ Eyewipes twice a day to clean the eyelid debris along with standard therapy (antibiotic and lubricants) and participants in group II followed lid hygiene with warm compresses along with standard therapy. Symptoms, ocular surface assessment (lipid layer thickness, tear meniscus height, non-invasive tear film breakup time, and meibography), slit-lamp biomicroscopy (eyelash contamination, meibomian gland blockage, meibomian gland secretion, and meibomian gland telangiectasia) and tear film osmolarity were noted at baseline and 90 days after therapy.Results:Significant improvement in symptoms and signs of MGD was observed in both groups after treatment (P < 0.001); however, the clinical improvement was better with the use of eyelid wipes. Lipid layer thickness increased significantly in group I (P = 0.0006) and group II (P = 0.0002), which was maintained even after adjusting for sociodemographic variables such as age, sex, and severity score of symptoms and signs.Conclusion:Lipid layer thickness of the tear film is a sensitive marker in monitoring response to treatment in patients with MGD. The use of physiological detergent-free eyelid wipes is non-inferior to lid hygiene and warm compresses, which remains the mainstay for treatment of MGD; the clinical improvement with eyelid wipes was noted to be better.     

慢性乙型肝炎组织中肝前体细胞的免疫组化特征

目的研究肝前体细胞（hepatic progenitor cells,HPCs）、小管样反应、中间型肝细胞在慢性乙型肝炎组织中的分布特征和数量变化,以及与肝细胞再生之间的可能联系。方法对42例慢性乙型肝炎组织行常规病理HE染色,按炎症活动度（G）分为轻、中、重三度,免疫组织化学方法观察肝胆细胞标记（AFP、GST-π、CK7、CK19）和造血干细胞标记（c-kit、CD34）的表达,并以Ki-67标记增殖的肝细胞,用CK7／CK19作为标记物对符合定义的HPCs、中间型肝细胞进行计数,小管样反应程度的判定利用彩色病理图象分析系统。结果慢性乙型肝炎的早期阶段即存在HPCs的活化和小管样反应,其数量随着炎症活动度的增加而增加,均表达CK7、CK19、GST-π和AFP,肝细胞增殖指数在轻、中度肝炎中逐渐增加,重度肝炎、肝硬化患者增殖的肝细胞数下降,而中间型肝细胞数量显著增加。小管样反应面积百分比与HPCs数目正相关（r=0．739,P〈0．05）,中间型肝细胞数目与HPCs数目正相关（r=0．614,P〈0．05）。结论慢性乙型肝炎中不仅有成熟肝细胞增殖,也存在肝前体细胞活化和分化,可能参与肝脏损伤后的再生修复。     

Long-lasting renal dysfunction following tacrolimus induction therapy in ulcerative colitis patients

Although tacrolimus (TAC) has remarkable effects in ulcerative colitis (UC) patients when given as remission induction therapy, some can develop renal dysfunction during TAC administration, resulting in withdrawal, though related details remain poorly understood. This study was conducted to determine the impact of oral TAC on renal function for remission induction therapy in UC patients. Fifty-five patients (10 elderly, 45 non-elderly) with UC and treated with oral TAC at our hospital were retrospectively evaluated. Renal function was assessed using estimated glomerular filtration rate (eGFR). Although a high clinical response to TAC was seen in both elderly and non-elderly, a decline in eGFR was noted in nearly all patients regardless of age, with a maximum change of −34.4% from the baseline value at week 11. Furthermore, eGFR decline recovered quickly after TAC discontinuation, though did not return to the baseline at two years following cessation. The rate of eGFR change at week 12 was significantly associated with patient age (β = −0.3242, p = 0.0103) and peak serum trough level during TAC treatment (β = 0.3563, p = 0.0051). Furthermore, the rate of decline in eGFR was significantly greater during treatment with TAC in the elderly as compared to non-elderly, with a large difference in eGFR decline rate between those groups also noted at two years after withdrawal of treatment. Careful attention to renal function when administering oral TAC for UC is important and changes in eGFR should be monitored closely in elderly patients even after treatment cessation.

孕母甲状腺功能异常对子代的影响

妊娠期母体甲状腺激素会发生一系列变化,而子代的生长发育,尤其是甲状腺的发育,对母体甲状腺功能状态有很大的依赖性.孕母甲状腺功能异常若未及时发现和控制,会引起子代各种严重的不良后果,包括流产、早产、死胎、死产、先天性畸形、甲状腺功能亢进症或甲状腺功能减退症、神经系统发育落后等,甚至影响子代远期的生长发育,因此应及早检出并控制孕妇及子代的甲状腺功能异常,以提高子代存活率及生活质量.
