Effect of N-acetylcysteine aerosol inhalation on serum levels of inflammatory factors and immune function in children with upper airway cough syndrome

Effects of ganciclovir combined with recombinant human interferon-α on clinical efficacy and immune function in children with infectious mononucleosis.

To evaluate the effects of ganciclovir combined with recombinant human interferon on clinical efficacy and immune function of children with infectious mononucleosis(IM). This was a retrospective study. Children (n=120) with IM hospitalized in Beijing Children's Hospital Affiliated to Capital Medical University Baoding Hospital from January 2020 to January 2022 were selected and randomly divided into study group and control group((n=60). Patients in the control group were treated with ganciclovir by intravenous infusion, and patients in the study group were given ganciclovir+recombinant human interferon-α1b. The time for eliminating clinical symptoms, the levels of inflammatory cytokines, immune function condition and T-lymphocyte subsets between the two groups were compared and analyzed. After treatment, the time for body temperature returned to normal, time for recovery from cervical lymphadenopathy, time for recovery from hepatosplenomegaly and time for disappearance of angina and oral mucosal congestion in the study group were significantly shorter than those in the control group(p= 0.00); after treatment, the levels of TNF-a and IL-6 in the study group were significantly lower than those in the control group; the indexes of CD3+ and CD8+ in the study group were significantly lower than those in the control group; after treatment, the levels of CD4+ and CD4+/CD8+ in the study group were significantly higher than those in the control group. Ranciclovir combined with recombinant human interferon-α1b, rapid improvements of clinical symptoms, significantly decreased inflammatory cytokines, improved T-lymphocyte function and no significant increase in adverse drug reactions were found in children with IM.

Intestinal microbiota and probiotic intervention in children with bronchial asthma

ObjectiveThis study aims to understand the differences in intestinal flora, expression of helper T cells, allergy-related indicators, and cytokine levels between children with bronchial asthma and healthy children. The study seeks to clarify the effectiveness and safety of probiotic preparations in the treatment of bronchial asthma in children, and to provide new methods for the treatment of bronchial asthma. MethodsA total of 66 pediatric patients aged 3–6 years with bronchial asthma and 35 healthy children undergoing physical examination during the same period were enrolled, designated as the asthma group and the healthy group, respectively. The asthma group was further divided into the probiotic group and the non-probiotic group based on whether probiotics were used. The gut microbiota, serum IgE antibody levels, cytokines (IL-4, IL-5, IL-9, IL-13 levels), proportions of helper T cells (Th1, Th2), and hypersensitive C-reactive protein were measured and compared among the groups. ResultsChildren with bronchial asthma had decreased abundance and reduced diversity of intestinal flora compared to the healthy group. At the genus level, the asthma group showed increased abundance of Bacteroides and decreased abundance of Faecalibacterium and Veillonella; The probiotic group demonstrated a significantly higher improvement in the abundance of these genera before and after treatment compared to the non-probiotic group (P < 0.05). Compared to the healthy group, children with asthma had elevated levels of serum IgE, IL-4, IL-5, IL-9, and IL-13, as well as a decreased Th1/Th2 ratio, all of which showed statistical differences (P < 0.05). After treatment, all immune indicators improved. Specifically, the probiotic group exhibited a more significant decrease in serum IgE, IL-4, and IL-13 levels compared to the non-probiotic group (P < 0.05). ConclusionChildren with bronchial asthma exhibit dysbiosis of intestinal flora, characterized by an increased abundance of the Bacteroides and decreased abundance of the Faecalibacterium and Veillonella. This imbalance in intestinal flora increases the risk of allergic diseases. Probiotics can effectively improve dysbiosis of intestinal flora, contributing to the balance of immune function in children, and can be used as an adjunct therapy for the treatment of bronchial asthma.

Use of Antibiotic and Gut Microbiota Dysbiosis: Role of Immune Function in Iraqi Children

Antibiotic use and its abeyant effect on gut microbiota dysbiosis are key issues for Iraqi children's immune function. The equilibrium of gut microbiota is vital for immune system modulation, the development of a strong defense adjoin infections, and the abstention of autoimmune diseases. Misuse or inappropriate use of antibiotics, which is usually acquired by factors such as infections repetition or cultural practices, can agitate this antithesis and aftereffect in dysbiosis. The aim of this investigation is to acquisition out how frequently antibiotics are acclimated in Iraqi children and whether this use is associated to abnormalities in their gut microbiome. We additionally aim to investigate how these disturbances may aftereffect these children's allowed function. Materials and Methods: 70 Iraqi child in age range (2-8) have been involved in cross sectional study to assess the effect of antibiotics on both gut dysbiosis and immune. Results: This study shows that the sample has a gender imbalance, with more women than men, and modest age variety. Of the total population, 55.72% live in cities, 88.57% report having no health issues, with asthma being the most common at 5.71%. The frequency of antibiotic usage has a major effect on gut bacteria; higher use is associated with fewer helpful species and more dangerous ones.

Clinical analysis of the effect of helicobacter pylori infection on immune function in children with peptic ulcer.

To study whether children with peptic ulcer would have abnormalities in cellular and humoral immune functions, and whether Helicobacter pylori (Hp) infection would affect the immune function of children with peptic ulcer. This is a retrospective study. The subjects of study were 72 children with diagnosed and cured peptic ulcer (ulcer group), and 50 healthy children with physical examination (control group) at Baoding Hospital, Beijing Children's Hospital Affiliated to Capital Medical University from June 2020 to December 2022. Further detection was conducted on T lymphocyte subsets (CD3+, CD4+, CD8+, and CD4+/CD8+ ratio) and immunoglobulin levels. Of the 72 children with peptic ulcer, 53(73.6%) were positive for Hp (Hp-positive group) and 19 (26.4%) were negative (Hp-negative group). The levels of CD3+, CD4+, and CD4+/CD8+ ratio in the control group were significantly higher than those in the ulcer group, with statistically significant difference (P<0.05); while the level of IgG in the control group was lower than that in the ulcer group, with statistically significant difference (P<0.05). Meanwhile, there were statistically significant differences in that the levels of CD3+, CD4+ and CD8+ were increased in Hp-positive group than those in Hp-negative group before treatment (P<0.05); while CD4+/CD8+ ratio was lower in the former group than that in the latter group, with statistically significant difference (P<0.05). Hp infection can induce the elevation of T lymphocyte subsets. The development of peptic ulcer has an intimate association with the disorder of cellular and humoral immune functions.

Impact of steroids on the immune profiles of children with asthma living in the inner-city.

Background: Inner-city asthma is associated with high morbidity and systemic steroid use. Chronic steroid use impacts immune function; however, there is a lack of data with regard to the extent of immunosuppression in patients with asthma and who are receiving frequent systemic steroids. Objective: To identify the impact of frequent systemic steroid bursts on the immune function of children with asthma who live in the inner city. Methods: Children ages 3-18 years with asthma were divided into study (≥2 systemic steroid bursts/year) and control groups (0-1 systemic steroid bursts/year). Lymphocyte subsets; mitogen proliferation assay; total immunoglobulin G (IgG) value, and pneumococcal and diphtheria/tetanus IgG values were evaluated. Results: Ninety-one participants were enrolled (study group [n = 42] and control group [n = 49]). There was no difference in adequate pneumococcal IgG value, diphtheria/tetanus IgG value, mitogen proliferation assays, lymphocyte subsets, and IgG values between the two groups. Children who received ≥2 steroid bursts/year had a significantly lower median pneumococcal IgG serotype 7F value. Most of the immune laboratory results were normal except for the pneumococcal IgG value. Most of the participants (n/N = 72/91 [79%]) had an inadequate pneumococcal IgG level (<7/14 serotypes ≥1.3 µg/mL). The participants with inadequate pneumococcal IgG level and who received a pneumococcal polysaccharide vaccine 23 (PPSV23) boost had a robust response. There was no significant difference in infection, steroid exposure, asthma severity, or morbidities between those with adequate versus inadequate pneumococcal IgG values. Conclusion: Children with asthma who live in the inner city and receive ≥2 steroid bursts/year do not have a significantly different immune profile from those who receive ≤1 steroid bursts/year do not have a significantly different immune profile from those who do not. Although appropriately vaccinated, most participants had an inadequate pneumococcal IgG level, regardless of steroid exposure and asthma severity. These children may benefit from PPSV23.

Effect of rituximab on immune status in children with aggressive mature B-cell lymphoma/leukemia–a prospective study from CCCG-BNHL-2015

BackgroundLimited research has been conducted on the impact of rituximab on immune function and the incidence of side effects in children undergoing combination chemotherapy for aggressive mature B-cell lymphoma/leukemia. MethodsClinical data from 85 patients with primary pediatric aggressive mature B-cell lymphoma/leukemia, treated according to the Chinese Children's Cancer Group (CCCG)-mature B-cell non-Hodgkin lymphoma (BNHL)-2015 protocol from June 1, 2015, to December 1, 2022, were collected from three tertiary medical centers in China. Patients with pre-existing malignancies or primary immune deficiencies (PIDs) were excluded. ResultsBetween June 1, 2015, and December 1, 2022, 85 patients (65 [76.5%] boys and 20[23.5%] girls; mean age, 6.95 years) were enrolled, and immune data at baseline during follow-up were analyzed. At the end of chemotherapy, a higher proportion of patients in the R4 group exhibited a decrease in peripheral blood CD3− CD19+ B cells (20[100%] of 20 vs 13[47.8%] of 18, p = 0.04), CD3+ T cells (21[91.3%] of 23 vs 14[60.9%] of 23, p = 0.016), and serum IgM (14[60.9%] of 23 vs 4[17.4%] of 23, p = 0.003) compared to the R3 group. However, these differences were no longer statistically significant six months after chemotherapy administration. The combination of rituximab with AA was associated with a higher incidence of significant thrombocytopenia (49[81.7%] of 60 vs 29[52.7%] of 55, p = 0.001) and infection (35[58.3%] of 60 vs 17[30.9%] of 55, p = 0.003) compared to AA alone. Furthermore, the combination of rituximab with BB was linked to a higher incidence of significant thrombocytopenia (32[52.5%] of 61 vs 31[31.0%] of 100, p = 0.007) compared to BB alone. ConclusionsWhile the effects of rituximab in combination with intense chemotherapy for childhood aggressive mature B-cell lymphoma/leukemia on children's immune function generally recovers within six months it may still prolong the recovery from immunoglobulinemia, posing a risk of secondary infections. Further studies are required to identify children with potential primary immunodeficiencies.

Per- and poly-fluoroalkyl substances (PFAS) effects on lung health: a perspective on the current literature and future recommendations.

Per- and poly-fluoroalkyl substances (PFAS) are a broad class of synthetic compounds widely used in commercial applications. The persistent nature of PFAS in the environment has earned them the epithet "forever chemicals." Concerns arise from widespread exposure to PFAS from occupational, household, and environmental sources. This widespread use of PFAS is particularly concerning, as emerging epidemiological evidence highlights their adverse effects on lung health. Such adverse impacts include impaired fetal lung development, reduced immune function in children, and potential links to lung cancer. Both in vivo and in vitro studies illuminate potential mechanisms underlying such adverse health outcomes subsequent to PFAS inhalation exposure, which may include immunomodulation, oxidative stress, and disruptions to epithelial barriers. However, evidence-based information focusing on the mechanisms of PFAS-mediated lung injury is lacking. Additionally, the discrepancies between data collected from animal and epidemiological studies highlight the need for improved approaches to better understand the toxicity results of PFAS exposure. To address these gaps, we recommend leveraging route-to-route extrapolation for risk assessment, prioritizing research on understudied PFAS, and adopting physiologically relevant, high-throughput approaches. These strategies are aimed at enhancing our understanding of PFAS inhalation effects, aiding in more informed risk management decisions. In this review, we summarize the current literature on PFAS exposure, emphasizing its adverse effects on lung health, particularly through inhalation. We then discuss the current knowledge on mechanisms underlying tissue- and cellular-level adverse outcomes caused by PFAS.

Clinical characteristics of SARS-CoV-2 Omicron variant infection in children with acute leukemia.

Hematologic diseases and various therapeutic stages can impact the presentation of SARS-CoV-2 Omicron variant infection. This study retrospectively analyzed data on Omicron infection in children with acute leukemia treated at our hospital between January 16, 2023, and February 25, 2023, using questionnaires. The prevalence of Omicron infection in children undergoing consolidation chemotherapy, maintenance chemotherapy, drug withdrawal, and healthy children was 81.8%, 75.2%, 55.2%, and 61.9%, respectively. The observed differences were statistically significant (P < 0.05). During the course of infection, children with leukemia undergoing chemotherapy, including both the consolidation and maintenance chemotherapy groups, exhibited a prolonged time to achieve SARS-CoV-2 negativity compared to the drug withdrawal and healthy groups. However, there was no significant increase in the incidence of symptoms across all body systems, and no children experienced serious sequelae or death. Furthermore, our observations indicated that all manifestations of Omicron infection in children with leukemia after drug withdrawal were not significantly different from those in healthy children. This suggested, to a certain extent, that the immune function of children with leukemia recovers effectively after the cessation of drug treatment. These findings are crucial for guiding clinical management and alleviating concerns about infection for both children with leukemia and their parents.

Ex vivo exposure to polybrominated diphenyl ether (PBDE) selectively affects the immune response in autistic children

Children on the autism spectrum have been shown to have immune dysregulation that often correlates with behavioral deficits. The role of the post-natal environment in this dysregulation is an area of active investigation. We examined the association between plasma levels of polybrominated diphenyl ether (PBDE) and immune cell function in age-matched autistic children and non-autistic controls. Plasma from children on the autism spectrum (n = 38) and typically developing controls (TD; n = 60) were analyzed for 14 major PBDE congeners. Cytokine/chemokine production was measured in peripheral blood mononuclear cell (PBMC) supernatants with and without ex vivo BDE-49 exposure. Total plasma concentration (∑PBDE14) and individual congener levels were also correlated with T cell function. ∑PBDE14 did not differ between diagnostic groups but correlated with reduced immune function in children on the autism spectrum. In autistic children, IL-2 and IFN-γ production was reduced in association with several individual BDE congeners, especially BDE-49 (p = 0.001). Furthermore, when PBMCs were exposed ex vivo to BDE-49, cells from autistic children produced elevated levels of IL-6, TNF-α, IL-1β, MIP-1α and MCP-1 (p < 0.05). Therefore, despite similar plasma levels of PBDE, these data suggest that PBMC function was differentially impacted in the context of several PBDE congeners in autistic children relative to TD children where increased body burden of PBDE significantly correlated with a suppressed immune response in autistic children but not TD controls. Further, acute ex vivo exposure of PBMCs to BDE-49 stimulates an elevated cytokine response in AU cases versus a depressed response in TD controls. These data suggest that exposure to the toxicant BDE-49 differentially impacts immune cell function in autistic children relative to TD children providing evidence for an underlying association between susceptibility to PBDE exposure and immune anomalies in children on the autism spectrum.

Immune system dysfunction in purulent inflammatory diseases of the maxillofacial area in pediatric patients

The issues of treatment of purulent inflammatory diseases of the maxillofacial region (PMMA) are quite urgent, due to increasing number of such patients. Their clinical course is getting worse, and the efficiency of antibiotic therapy is decreasing. Clinical outcomes of purulent maxillofacial pathology in children are complicated by potential severe local deformities at the growth areas of the jaw bones which are difficult to eliminate. The number of cases of prolonged and chronic inflammatory processes, development of local and general complications is increased. The reason for these complications may be an impaired susceptibility to infectious agents, which is determined by the state of the immune system. Therefore, our aim was to reveal some features of immune functions in children with purulent-inflammatory diseases of maxillofacial area.&#x0D; The study included a group of pediatric patients 8-17 years old with maxillofacial inflammatory diseases of the maxilla (the study group), and 13 conditionally healthy children (the comparison group). The contents of T cells (CD3+CD19-, CD3+CD4+, CD3+CD8+, CD3+CD4+/CD3+CD8+), and В cells (CD3-CD19+), NK (CD3-CD16+CD56+) was determined using Cytomics FC-500 (Beckman Coulter, USA);concentrations of serum IgA, IgM, IgG were determined by ELISA technique (Vector-Best, Russia). Phagocytic activity of neutrophilic granulocytes (NG) was evaluated as percentage of actively phagocytic NGs, capturing processes were assessed by appropriate phagocytic indices, and the digestive activity was evaluated against S. aureus (strain 209).&#x0D; Combined defects of immune response in children with maxillofacial hypertension were established: decrease of T lymphocytes contents along with decrease of T helpers and CTL ratio along with unchanged content of NK cells and B lymphocytes. Increase of IgA and IgG levels was also found. Defects of phagocytosis were revealed, primarily connected with the processes of completed phagocytosis and increased content of actively phagocytizing NG.&#x0D; Treatment of children suffering with purulent inflammatory diseases of maxillofacial region is still an urgent problem in dentistry. The revealed dysfunction of immune response to pathogens in the purulent maxillofacial disorders may explain a prolonged clinical course of inflammatory processes, thus determining a need for usage of immunotropic therapy in complex treatment schedules including operative aid as well as conventional drug and physiotherapeutic treatment aiming for increase of rehabilitation efficiency and prevention of postoperative complications in these patients.

Effect of co-administration of pranoprofen/emedastine difumarate eye drops on efficacy, inflammatory factors, tear film stability and immune function in children with allergic conjunctivitis

Purpose: To investigate the clinical efficacy of pranoprofen eye drops when combined with emedastinedifumarate eye drops for the treatment of children with allergic conjunctivitis.Methods: A total of 96 children with allergic conjunctivitis admitted to Eye Hospital, China Academy of Chinese Medical Sciences from January 2020 to 2022 were enrolled in this study. They were divided into study group (treated with both pranoprofen eye drops and emedastine difumarate eye drops), and control group (treated with emedastine difumarate eye drops alone), with 48 children in each group. The control group was given emedastine fumarate eye drops 1 drop twice a day. The study group was given pranoprofen eye drops 2 drops 4 times a day in addition to the treatment administered to control group. Patients in both groups were observed and compared after one week of treatment. Efficacy, incidence of adverse reactions, symptom scores, inflammatory factors, tear film stability indicators and immune function indicators were assessed and recorded.Results: Prior to treatment, there was no significant difference in symptom score, inflammatory factors, tear film stability indicators and immune function indicators between study and control groups. Although the above indicators improved in both groups after treatment, the study group showed significantly greater improvement than control group (p &lt; 0.05). Overall clinical response rate in the study group (95.83 %) was higher than in the control group (77.08 %), while the incidence of adverse reaction in the study group (6.25 %) was lower than that of control group (27.08 %, p &lt; 0.05).Conclusion: Pranoprofen eye drops, when combined with emedastine difumarate eye drops for treatment of children with allergic conjunctivitis, is more effective than the use of emedastine difumarate eye drops alone. However, further clinical trials are required to validate the findings of this study prior to adoption of the combination treatment in clinical practice.

In utero effects of opioids on fetal growth

Background Studies indicate antenatal opioid use is associated with birth size deficits, as evidenced by reductions in birth weight and head circumference. However, there remains a limited understanding of how early this growth restriction occurs, and what specific parameters are affected. This novel study evaluated global and specific growth deficits associated with prenatal opioid exposure between 18–22 weeks’ gestation as assessed during anatomy ultrasounds. Methods Pregnant women who completed an anatomy ultrasound were identified via electronic medical records from a large academic obstetric practice. The study group used opioids, with tobacco and/or marijuana use permitted (n = 41). The control group could have used tobacco and/or marijuana, but not opioids (n = 308). Neither group had alcohol or other drug exposure. Records were reviewed for medical history and ultrasound size parameters, coded as percentiles for gestational age. Results Demographics and medical histories were compared with several significant differences noted. After controlling for these differences, significant (p < 0.05) growth deficits were identified in opioid-exposed fetuses. Specifically, reductions >10 percentile points were observed in head circumference, biparietal diameter, and humerus length for opioid-exposed fetuses compared to controls. Additionally, intrauterine growth restriction (IUGR) was diagnosed five times more often. Femur length was significantly reduced in opioid-exposed fetuses prior to adjustment for confounding (p = .016), but this reduction was not significant (p = .072) after controlling for background differences. Estimated fetal weight (p = .274) and abdominal circumference (p = .633) were not significantly different between exposure groups. Conclusion Fetal opioid exposure predicted various bone growth deficits during routine anatomy ultrasound, indicating the effects of opioid exposure on size deficits may be evident as early as 18–22 weeks’ gestation. These findings may also suggest that in utero opioid exposure negatively impacts bone growth specifically rather than weight or fat/muscle mass. Additional studies with larger sample sizes may also reveal significantly reduced femur length, further supporting a negative impact on bone growth. Future studies evaluating bone health and immune function in children after antenatal opioid exposure may help clarify this specific effect of opioids on bone development.

Effect of tonsillotomy on the inflammation and immune function in children with chronic tonsillitis

Objective:To investigate the changes of inflammation and immune function in children with chronic tonsillitis after tonsillotomy. Methods:Prospectively collected 60 children with obstructive sleep apnea （OSA） diagnosed as chronic tonsillitis with adenoids and tonsillar hypertrophy from January to June 2021. Two groups were divided, the experimental group （n=30） underwent bilateral partial tonsillectomy + adenoidectomy by hypothermia plasma ablation, and the control group （n=30） underwent adenoidectomy by using the same hypothermia plasma ablation method. The number of tonsillitis attacks before surgery and within one year after surgery was recorded, and the serum immunoglobulin IgM, IgG, IgA, complement C3 and complement C4 levels before operation, one month and three months after operation were measured. Results:The number of tonsillitis attacks in the experimental group and the control group at one year after surgery was lower than that before surgery（P<0.05）; The number of inflammatory attacks in the experimental group was （0.50±0.63） times/year, which was lower than that of （1.33±0.80） times/year in the control group. There was no significant difference in the five immunization results of the two groups at one month and three months after operation compared with before operation, and there was also no significant difference between the experimental and the control groups. Conclusion:Partial tonsillectomy can be applied to children with chronic tonsillitis, which can effectively reduce the number of tonsillitis attacks and has no effect on the immune function of children.

Clinical Efficacy and Immune Function of Andrographolide Sulfonate in Children with Mycoplasma Pneumoniae Pneumonia.

To figure out the effect of andrographolide sulfonate on the clinical efficacy and immune function of children with mycoplasma pneumoniae pneumonia (MPP). From January 2019 to April 2021, a total of 102 children with MPP were selected as the research group. They were assigned into the control and the observation groups by random number table method, with 51 cases/group. The control group was given routine treatment, and the observation was given andrographolide sulfonate treatment. The therapeutic efficacy and improvement of clinical symptoms were compared between the two. The changes of immune function, pulmonary function, myocardial enzymology indexes, MCP-4, IL-1β, IFN-γ, and TNF-α were noticed in the groups before and after treatment. The presence of drug-related adverse reactions of patients was recorded during treatment. The total effective rate of treatment in the observation group was higher, and the time of fever reduction, pulmonary rales disappearance and cough disappearance time were all shorter vs. the control group (p < 0.05). Immunoglobulin G (IgG), immunoglobulin A (IgA), and immunoglobulin M (IgM) in the observation group after treatment were higher, and monocyte chemoattractant protein 4 (MCP-4), interleukin-1β (IL-1β), interferon-γ (IFN- γ), and tumor necrosis factor-α (TNF-α) were reduced vs. the control group. The forced expiratory volume in the 1st second (FEV1) and the percentage of forced vital capacity occupied by the forced expiratory volume in the first second (FEV1/FVC) and peak expiratory flow (PEF) values were higher (p < 0.05), but aspartate aminotransferase (AST), lactate dehydrogenase (LDH), and creatine kinase (CK) and isoenzyme (CK-MB) were reduced in the observation group after treatment vs. the control group (p < 0.05); No serious adverse reactions took place in the two during treatment. The treatment of andrographolide sulfonate in children with MPP can enhance the therapeutic effect, ameliorate the immune function and lung function of children, and reduce inflammation and myocardial enzymes.

Clinical Efficacy of Sublingual Specific Immunotherapy in Children with Allergic Rhinitis and its Impact on their Inflammatory Factors and Immune Function

The main objective of this study is to analyze the effects of sublingual specific immunotherapy and conventional drug therapy on inflammatory factors and immune function in children with allergic rhinitis. The research subjects were divided into three groups, group A received sublingual administration of dust mite drops, group B received routine treatment such as passive intervention with topical hormones, antihistamines and nasal irrigation and group C received sublingual administration of dust mite drops and on the basis of drop therapy, conventional treatments such as topical and systemic use of corticosteroids, antihistamines and anti-leukotriene’s are combined. Comparison was done among the three different sets of indicators. After treatment, the allergic rhinitis symptom score, visual analog scale score and inflammatory factor index levels in the three groups were calculated. The score was lower in group A than in group B and lower in group C than in group A. Adverse reactions were lowest in group A and highest in group C. After treatment, the levels of whole blood cluster of differentiation 4+, cluster of differentiation 4+/cluster of differentiation 8+ cells and serum immunoglobulin E were lower in group C than group A, and lower in group B than group A. The cluster of differentiation 8+ index was highest in group C and lowest in group B. Sublingual specific immunotherapy is effective and safe for children with allergic rhinitis.

Cord blood immune profile: Associations with higher prenatal plastic chemical levels

Prenatal exposure to plastic chemicals has been associated with alterations to early-life immune function in children. However, previous studies have generally been small and focused on limited repertoires of immune indices. In a large population-based pre-birth cohort (n = 1074), third-trimester measurements of eight phthalate metabolites and three analogues of bisphenols were used to estimate prenatal exposure to phthalate and bisphenol compounds. In cord blood, immune cell populations were measured by flow cytometry and an extensive panel of cytokines and chemokines were measured by multiplex immunoassay. We used these cord blood analytes to estimate “early life” immune profiles. The full study sample comprises data from 774 infants with prenatal plastic metabolite measurements and any cord blood immune data. Multiple linear regression analysis was used to evaluate whether prenatal phthalate and bisphenol exposure was prospectively associated with cord blood immune cell populations and cytokine and chemokine levels. Generally, inverse associations were observed between prenatal phthalate exposure and cord blood immune indices. Higher exposure to di-n-butyl phthalate was associated with lower cord blood levels of platelet-derived growth factor (PDGF) and interferon gamma-induced protein 10 (IP-10); higher exposure to the sum of dibutyl phthalates was associated with lower cord blood levels of IP-10; and higher exposure to benzyl butyl phthalate was associated with lower cord blood levels of interleukin 1 beta (IL-1β). There was less evidence of associations between bisphenols and cord blood immune indices. These results extend previous work examining prenatal plastic chemical exposure and early-life immune development and highlight the importance of further examination of potential associations with health-related outcomes.

Influences of Bifid Triple Viable Capsules Plus Cetirizine on Gut Microbiota and Immune Function in Children with Eczema.

ObjectiveInfantile eczema (IE), a common pediatric allergic skin disease caused by multiple inherent and external factors, is common in infants and young children, with skin lesions and itching as the main clinical manifestations. At present, its pathological mechanism has not been thoroughly clarified, but scholars believe that it is related to the joint action of various internal and external factors. This research aims to investigate the influences of bifid triple viable capsules plus cetirizine (CTZ) on gut microbiota (GMB) and immunity in children with eczema.MethodsThe complete clinical data of 162 cases of IE presented between July 2019 and July 2020 to the First Hospital of Shanxi Medical University were retrospectively analyzed. Children treated by CTZ alone were assigned to the control group (n = 81) and those by CTZ plus bifid triple viable capsules were included in the observation group (n = 81). Therapeutic efficacy, adverse reactions (ARs), disease recurrence, as well as changes in GMB, inflammatory factors (IFs) and immunoglobulins (Igs) were observed.ResultsThe observation group was observed with a higher overall response rate and increased fecal Lactobacillus, Escherichia coli (E. coli) and Bifidobacterium counts after treatment versus the control group. After treatment, reduced IgG and IgM, as well as IFs, were found in both groups, with lower levels in the observation group. A lower incidence of ARs was determined in the observation group.ConclusionWith high efficacy for the treatment of IE, bifid triple viable capsules plus CTZ can validly regulate the GMB of children, improve their immune function and clinical symptoms, and reduce the disease recurrence rate, which is worthy of clinical promotion.

Clinical Efficacy of Immunoglobulin Combined with Glucocorticoids in the Treatment of Oculomotor Myasthenia Gravis in Children and the Effect on Serum Immunity.

To investigate the effects of treatment with immunoglobulin on clinical outcomes and immune function in children with oculomotor myasthenia gravis. The clinical data of 100 pediatric patients with oculomotor myasthenia gravis treated in our hospital from January 2019 to December 2021 were selected as the subjects of this retrospective study and divided into a comparison group and a treatment group according to the different treatment methods. The comparison group was treated with glucocorticoids, and the treatment group was treated with immunoglobulin on the basis of the comparison group. The differences in the serum indexes, the effects of immune function, and the clinical efficacy of the two groups were observed and compared. It was found the comparison of immunoglobulin G (IgG), immunoglobulin A (IgA), and immunoglobulin M (IgM) after treatment was significantly different and lower in the treatment group than in the comparison group; the comparison of CD4+, CD3+, CD4+/CD8+, and NK cells after treatment was significantly different and higher in the treatment group than in the comparison group. The effective rate of 98.00% in the treatment group was significantly higher than that of 76.00% in the comparison group, and the difference was statistically significant. The clinical efficacy of the two groups showed that the fever, cough, sputum, myasthenia gravis crisis, and gastrointestinal reactions in the treatment group were significantly lower than those in the comparison group. The study indicates that comparative study of children with oculomotor myasthenia gravis treated with immunoglobulin combined with glucocorticoids is more effective, effectively improving the immune level of patients and reducing adverse reactions.

Laparoscopic management of benign splenic tumors in children

BackgroundThe splenic tumor is relatively rare in children. However, diagnosing and managing this disease remain controversial. This study aimed to evaluate the clinical characteristics and pathological features of benign splenic...
