RESUMEN
This is a retrospective study whose main objective was to analyze the influence of the Polish Guidelines for the Management of Respiratory Tract Infections of 2010 (PGMRTI) on in-hospital treatment of children with community-acquired pneumonia (CAP). Files from four Warsaw hospitals were reviewed to identify children with uncomplicated CAP, treated before (2008-2009) (pre-PGMRTI) and after (2011-2012) (post-PGMRTI) publication of the guidelines. Predefined data on the management were compared. A cohort of 2,359 children (1,081 pre-PGMRTI and 1,278 post-PGMRTI) was included. We found that co-amoxiclav was the most common first-line therapy in children >3 months of age (34.6% and 40.4% pre- and post-PGMRTI, respectively), followed by cefuroxime (31.8% and 20.9% pre- and post-PGMRTI, respectively; p < 0.0001) and macrolides (17.4% and 24.5% pre- and post-PGMRTI, respectively; p < 0.0001). Amoxicillin was rarely used (5.4% and 4.9%, pre- and post-PGMRTI, respectively). The study revealed an overuse of inhaled bronchodilators, corticosteroids, and mucoactive drugs. Blood diagnostic tests were applied to a significant percentage of patients: blood cultures (41.2% and 44.5% pre-and post-PGMRTI, respectively) and serology for atypical pathogens (27.9% and 44.9% pre-and post-PGMRTI, respectively; p < 0.0001). The number of follow-up chest X-rays increased (30.5% and 53.8% pre- and post-PGMRTI, respectively; p < 0.0001). In conclusion, the study demonstrates an unsatisfactory influence of the guidelines on in-hospital management of CAP in children. Despite an explicit recommendation for the use of amoxicillin, it was still underused. Other methods of education and guideline dissemination are needed to optimize the prescribing of antibiotics.

AIM OF THE STUDY: To assess the changes in the leukocyte profile and C-reactive protein (CRP) concentration in adolescents with excess fat mass after 6-12 months of dietary intervention. MATERIAL AND METHODS: The retrospective study included 99 overweight and obese adolescents, aged from 10.0 to 17.5 years, 82 of whom were re-hospitalized 6 to 12 months after dietary counseling. The control group consisted of 42 normal weight peers. Anthropometric measurements and laboratory tests were performed, homeostasis model assessment - insulin resistance (HOMA-IR) and triglycerides/high-density lipoprotein cholesterol (TG/HDL-C) ratio were calculated. RESULTS: Obese and overweight adolescents had higher white blood cells (WBC), neutrophil, monocyte counts and CRP concentration. In the backward stepwise regression analysis, body mass index standard deviation score (BMI SDS) and fasting insulin concentration were independent predictors of WBC and neutrophil counts at the baseline. At the follow-up visit in 45 (54.8%) children, who had lost weight, decreases in WBC, neutrophil and monocyte counts and CRP, fasting insulin, total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG) concentrations were observed. Changes in WBC and neutrophil counts were dependent on changes in HOMA-IR and TG/HDL ratio. Changes in HOMA-IR had a significant impact on changes in the monocyte count. CONCLUSIONS: Adipose tissue promotes systemic inflammation and its intensity depends on the degree of obesity and insulin resistance. This state is reversible. Changes in HOMA-IR were independent predictors of changes in WBC, neutrophil and monocyte counts after reduction of body weight.

Introduction: The growth hormone/insulin-like growth factor-1 axis (GH/IGF-1) is crucial for longitudinal bone growth and exerts several metabolic effects. It is debatable whether and how the recombinant human growth hormone (rhGH) treatment affects the trunk-limb proportions. Aim of the study: We aim to evaluate the changes in body proportions and body fat content in short children with growth hormone deficiency (GHD), children born small for gestational age (SGA), and girls with Turner syndrome (TS) during the first year of rhGH therapy. Material and methods: The data of 70 children with GHD, 40 children born SGA, and 36 girls with TS from 1998 to 2019 were analyzed. The following parameters were measured: height, body weight, sitting height, and two skinfolds on the arm above the triceps brachii and below the scapula at the beginning of rhGH therapy and after the first year of treatment. Sitting height and lower limb length were presented as percentages (%) of body height. Fat mass percentage (%FAT) was calculated using the Slaughter formula. Results: At the beginning of rhGH, TS girls had the greatest height deficit (-2.7 SDS), the highest sitting height (%), and the lowest lower limb length (%) compared to children with GHD and children born SGA. Moreover, TS girls had higher body weight SDS, BMI SDS compared to SGA children (p < 0.001), and higher %FAT compared to both GHD and SGA children (p < 0.001 for both). After the first year of rhGH therapy, a significant increase in lower limb share (%) and a decrease in %FAT were observed in all the study groups. TS girls still had significantly higher sitting height (%), shorter lower limbs (%), and higher %FAT, body weight SDS, and BMI SDS compared to children with GHD and children born SGA (p < 0.05 for all variables). Conclusions: Our results show that rhGH treatment could increase lower limb length in relation to height and reduce fat mass in treated children. Girls with TS had the largest baseline body disproportions and the highest body fat content. Despite a satisfactory reduction in height deficit, after the first year of rhGH therapy, these girls had still higher body weight SDS, BMI SDS, %FAT, the highest sitting height (%), and the lowest lower limb length (%) compared to children with GHD and born SGA.
RESUMEN
Kabuki Syndrome (KS) encompasses a spectrum of clinical manifestations, primarily attributed to pathogenic variants in the KMT2D gene. This study aims to elucidate novel features in KS patients with missense variants, contrasting their presentation with both literature-reported cases of patients with missense pathogenic variants as well as other KS patients with truncating pathogenic variants. Employing a survey questionnaire and clinical evaluations, we examined ten KS patients with missense variants, focusing on their dysmorphism characteristics, behavior and psychomotor development. We identified unique features in missense variant patients, including foot hyperesthesia, musicality, and sensory integration disorders. Notably, despite similarities in developmental trajectories, distinct phenotypic traits emerged in missense variant cases, suggesting a potential genotype-phenotype correlation. These findings contribute to a deeper understanding of KS heterogeneity and underscore the importance of genotype-specific characterization for prognostic and therapeutic considerations. Further exploration of genotype-phenotype relationships promises to refine clinical management strategies and enhance patient outcomes in this complex syndrome.
RESUMEN
UNLABELLED: In myocardial infarction, the endothelial activation which induces leukocytes migration into the myocardial tissues, may play an important role in ischemic injury. Selectins, shedding from the surface of activated cells into bloodstream, maybe suggested as markers of endothelial activation and leukocytes stimulation. The aim of the study was evaluation. To evaluate serum soluble E- and P-selectin levels as endothelial activation marker and serum soluble L-selectin level as leukocytes stimulation marker in myocardial infarction. MATERIAL AND METHODS: We examined 27 patients with acute myocardial infarction (AMI) The control group (K) consisted of 23 healthy subjects without symptoms of coronary artery disease. The concentration of soluble selectins (sE-, sP-, sL-selectin) were analyzed in venous blood serum. Results of routine laboratory tests: lipid levels, leukocyte count, prothrombin time were also included into statistical analysis. RESULTS: A significant decrease in serum sL-selectin level was observed in patients with acute myocardial infarction compared to the control group. However, no difference was found in sE- and sP-selectin levels between the patient group and the control group. The sE-selectin level correlated positively with triglicerides level and inversely with HDL cholesterol level. There were a positive correlation between sP-selectin level and leukocyte count as well as inverse correlation between sP-selectin level and prothrombin time. The sL-selectin level correlated positively with leukocyte count. There were also a positive correlation between sP-selectin level and sE-selectin as well as sL-selectin levels. CONCLUSIONS: The sE-selectin level increases with the severity of atherogenic changes in serum lipid profil, and sP-selectin level increases due to inflammatory and prothrombotic processes. The sL-selectin level is influenced by inflamamatory processes in the vascular wall. The sE- and sP-selectin levels, unchanged compared to the control group, do not reflect adequately the degree of endothelial activation. An decreased sL-selectin level may indicate functional depletion of leukocytes in patients with myocardial infarction and make it difficult to assess the degree of leukocytes stimulation.

Background: Vitamin D affects adipogenesis, oxidative stress, inflammation, secretion of adipocytokines, lipid metabolism and thermogenesis. Some researchers postulate that those effects could be exerted by the influence of vitamin D on chemerin levels. Aim of the study: We aimed to investigate if there is a link between serum 25-hydroksyvitamin D [25(OH)D], chemerin and metabolic profile in overweight and obese children before and after vitamin D supplementation. Material and methods: The prospective study included 65 overweight and obese children aged 9.08-17.5 years and 26 peers as a control. None of the patients in the study group had received vitamin D within the last twelve months before the study. Results: The study group had lower baseline 25(OH)D (p<0.001) and higher chemerin (p<0.001), triglycerides (TG, p<0.001), triglycerides/high density lipoprotein cholesterol (TG/HDL-C, p<0.001), C-reactive protein (CRP, p<0.05), fasting insulin (p<0.001), Homeostasis Model Assessment - Insulin Resistance (HOMA-IR, p<0.001), alanine aminotransferase (ALT, p<0.001) and uric acid (p<0.001) compared to the control group. Baseline vitamin D was related to fasting insulin (R=-0.29, p=0.021), HOMA-IR (R=-0.30, p=0.016), HDL-C (R=0.29, p=0.020) and uric acid (R=-0.28, p=0.037) in the study group. Baseline chemerin was related to insulin at 30' (R=0.27, p=0.030), 60' (R=0.27, p=0.033), 90' (R=0.26, p=0.037) and 120' (R=0.26, p=0.040) during the oral glucose tolerance test (OGTT) and ALT (R=0.25, p=0.041) in the study group. Correlation between vitamin D and chemerin (R=-0.39, p=0.046) was found only in the control group. After six months of vitamin D supplementation a decrease in CRP (p<0.01), total cholesterol (p<0.05), ALT (p<0.01), glucose at 150' OGTT (p<0.05) was observed. Moreover, we noticed a tendency for negative association between 25(OH)D and chemerin levels (p=0.085). Multivariable backward linear regression models were build using baseline vitamin D, baseline chemerin and six months chemerin as the dependent variables. Conclusions: Our study confirmed that vitamin D has positive effect on metabolic profile in overweight and obese children. The relationship between vitamin D and chemerin is not clear, nevertheless we have observed a tendency to decrease chemerin concentrations after improving vitamin D status, even without a significant reduction in body fat mass.

Background: Obesity is related to changes in adipokine secretion, activity of adipose tissue macrophages, helper T cells, and regulatory T cells. It has been confirmed that vitamin D has potent anti-inflammatory properties. It contributes to reduction in pro-inflammatory mediators and an increase in anti-inflammatory cytokines. There is also evidence that vitamin D could decrease C-reactive protein (CRP) and affect selected haematological indices. Aim of the Study: We aimed to evaluate the effect of vitamin D on interleukin (IL)-10, IL-17, CRP, blood leukocyte profile, and platelet (PLT) count in overweight and obese children before and after six months of vitamin D supplementation. Material and Methods: The study group consisted of 67 overweight and obese children aged 9.08-17.5 years. The control group included 31 normal weight peers age- and sex-matched. None of the studied children had received vitamin D supplementation before the study. Data were analyzed at baseline and after vitamin D supplementation. Results: The study group had lower baseline 25(OH)D (p<0.001) and higher white blood cell (WBC) (p=0.014), granulocyte (p=0.015), monocyte (p=0.009) and CRP (p=0.002) compared to the control group. In the study group, vitamin D levels were related negatively to nutritional status. Leukocyte profile parameters, PLT, CRP, IL-10 or IL-17 were not related to baseline 25(OH)D. Baseline IL-17 levels correlated with monocytes (R= 0.36, p=0.003) independently on 25(OH)D deficit. In children with vitamin D <15ng/ml, the baseline 25(OH)D was related to CRP (R=-0.42, p=0.017). After six months of vitamin D supplementation, we noticed a decrease in CRP levels (p=0.0003). Serum 25(OH)D correlated with IL-10 in that period (R=0.27, p=0.028). Moreover, we noticed that IL-10 correlated with monocyte (R=-0.28, p=0.023). We did not find any significant associations between 25(OH)D and leukocyte profile parameters, PLT, or IL-17. The multivariable stepwise regression analysis identified IL-10 as the parameter positively associated with 25(OH)D. Conclusions: Our study confirmed beneficial effects of vitamin D supplementation in overweight and obese paediatric populations. Vitamin D intake seems to exert its anti-inflammatory effect mainly via decreasing the CRP level and protecting stabile values of IL-10, rather than its impact on pro-inflammatory factors such as lL-17 and leukocyte profile parameters.
