Few data exist on long-term growth hormone (GH) treatment in patients with Noonan syndrome (NS).

To evaluate the effectiveness and safety of GH treatment in NS in clinical practice.

Height gain, near-adult height (NAH), and safety were assessed in 2 complementary non-interventional studies NordiNet® IOS and ANSWER. The safety analysis included 412 patients, and the effectiveness analysis included 84 GH-treated patients (male, n = 67) with ≥4 years' height standard deviation score (HSDS) data. HSDS was determined using national reference (NR) and NS-specific (NSS) data.

The mean (SD) baseline age was 8.38 (3.57) years; HSDS, -2.76 (1.03); GH dose, 41.6 (11.1) µg/kg/day. selleck inhibitor The mean (SD) HSDS increase from baseline (ΔHSDS) was 0.49 (0.37) (first year), 0.79 (0.58) (second year), and 1.01 (0.60) (third year) (NR). The mean (SD) HSDS at year 3 was -1.66 (1.00) (NR; 1.06 [1.12] [NSS]). Twenty-four patients achieved NAH. The mean (SD) NAH SDS (NR) was -1.51 (0.60) (154.90 [3.21] cm) in females and -1.79 (1.09) (165.61 [7.19] cm) in males; 70.8% (17/24) had NAH SDS ≥ -2. Adverse drug reactions and GH-unrelated serious adverse events (n = 34) were reported in 22/412 (5.3%) patients. Four neoplasms and 3 cases of scoliosis were reported; no cardiovascular adverse events occurred.

GH-treated children with NS achieved substantial height gain during the first 3 years of follow-up. Overall, 24 patients achieved NAH, with 70.8% having NAH SDS ≥ -2. There was no evidence to support a higher prevalence of neoplasm, or cardiac or other comorbidities.

The link between autoimmune gut disorders and different types of hair loss conditions has been recently investigated with an increased interest. With acknowledgement of the connection between immune dysregulation and the gut microbiome, this pathway is now becoming recognized as playing an important role in hair growth. The inflammatory cascade that results from the disruption of gut integrity such as seen in inflammatory bowel diseases (IBD) has been associated with certain types of alopecia.

The aim of this work was to evaluate the association between alopecia and IBD.

A primary literature search was conducted using the PubMed, Embase, and Web of Science databases to identify articles on co-occurring alopecia and IBD from 1967 to 2020. A total of 79 studies were included in the review. A one-way proportional meta-analysis was performed on 19 of the studies to generate the pooled prevalence of alopecia and IBD.

The pooled prevalence of non-scarring alopecia among IBD patients was 1.12% (k = 7, I2 = 98.6%, 95% CI 3.1-39.9); the prevalence of IBD among scarring and non-scarring alopecia was 1.99% (k = 12; I2 = 99%, 95% CI 6.2-34). The prevalence of non-scarring alopecia areata (AA) among IBD was compared to the prevalence of AA in the general population (0.63 vs. 0.1%; p < 0.0001). Similarly, the prevalence of IBD among the scarring and non-scarring alopecia groups was compared to the prevalence of IBD in the general population (1.99 vs. 0.396%; p = 0.0004).

IBD and alopecia, particularly AA, appear to be strongly associated. Dermatology patients with alopecia may benefit from screening for IBD.

The authors evaluated the changes in Tp-e interval, Tp-e/QT and Tp-e/corrected QT (QTc) ratios, and traditional electrocardiographic features of electrical dispersion in adults infected with Human Immunodeficiency Virus (HIV) and their study revealed that the cTp-e interval, Tp-e/QT and Tp-e/QTc ratios were prolonged and correlated to the severity of the disease in HIV-infected patients. Previous studies have revealed that the Tp-e interval, the Tpeak-Tend interval (Tpe), the interval from the T-wave peak to the end of the T wave, has been related to arrhythmogenesis, is specified as an index of totaldispersion of repolarization[2]. Prolonged Tp-e interval is predictable for ventricular arrhythmias and mortality [3]. Unal et al. showed that HIV-infected patients receiving combination antiretroviral therapy (cART) were associated withlonger Tp-e interval and Tp-e/QTc ratio and correlated positively with the duration of disease and the electrophysiologicalabnormalities, and negatively with CD4 count[4]. There were no informations about medical status of patients with HIV, duration of the disease and why hsCRP is higher in patients' group. The patients were in active phases of infection. We think that these are important datas for results of the study. We thank the authors for adding this article to the literature.

Phosphatidylcholine (PC) is intrinsically missing in intestinal mucus of patients with ulcerative colitis. Topical supplementation with delayed intestinal release PC formulations is assumed to compensate this lack. Three monocenter randomized controlled trials (RCTs) with a 30% PC-containing lecithin were successful, whereas 1 trial with >94% PC-containing lecithin failed.

Evaluation of 30% PC-containing lecithin provided in a delayed intestinal release formulation for treatment efficacy of ulcerative colitis was evaluated by meta-analysis of 3 RCTs.

Meta-analysis of 3 studies was performed using RevMan 5.3 software. Odds ratio (OR) and 95% Cl were calculated for remission, clinical and endoscopic improvement, histology, and life quality. p values <0.05 were accepted as significant.

The meta-analysis of 3 RTCs with 160 included patients with ulcerative colitis verified that PC improved the rate of remission (OR = 9.68), as well as clinical (OR = 30.58) and endoscopic outcomes (OR = 36.73). Within the available patient population, also histology and quality of life became better.
