Background. Alterations in thyroid hormones regulation and metabolism are frequently observed in patients with cirrhosis. Aims. To assess alterations in thyroid volume (TV), haemodynamics, and hormones in patients with cirrhosis and their relation to hepatic arterial haemodynamics, and disease severity. Methods. Forty cirrhotic patients were compared to 30 healthy subjects regarding TV, free triiodiothyronine (fT3), free tetraiodothyronine (fT4), thyroid stimulating hormone (TSH), and pulsatility and resistance indices in the inferior thyroid and hepatic arteries. Results. TV (P = 0.042), thyroid volume standard deviation score (TVSDS, P = 0.001), Inferior Thyroid Artery Pulsatility Index (ITAPI, P = 0.001), Inferior Thyroid Artery Resistance Index (ITARI, P = 0.041), Hepatic Artery Pulsatility Index (HAPI, P = 0.029) and Hepatic Artery Resistance Index (HARI, P = 0.035) were higher among cases being highest in Child-C patients. FT3 was lower in patients than controls (P = 0.001) and correlated negatively with ITAPI (r = −0.71, P = 0.021) and ITARI (r = −0.79, P = 0.011). ITAPI and ITARI correlated directly with HAPI and HARI (r = 0.62, P = 0.03, and r = 0.42, P = 0.04, resp.). Conclusions. Thyroid is involved in the haemodynamic alterations of cirrhosis. Routine study of thyroid by Doppler and assessment of thyroid functions should be performed in patients with cirrhosis to offer proper treatment if needed.

Background: Neonatal sepsis (NS) is a systemic uncontrolled inflammatory response to an infectious agent, resulting in oxidative stress. Melatonin antioxidant and free radical scavenger proved to be safe in neonates. We aimed to evaluate the efficacy and safety of melatonin as adjuvant therapy in NS. This was an interventional trial conducted on 40 preterm neonates with NS diagnosed on the basis of clinical and laboratory criteria. They were simply randomized to melatonin treated (MT) (n = 20) and conventionally treated (CT) (n = 20) groups. Melatonin was administered at a total dose of 20 mg enterally in two divided doses of 10 mg each, 1 h apart. Malondialdehyde (MDA) was assessed in patients at enrollment, 4 and 72 h later in MT, and 72hours later in CT. Fifteen healthy matched neonates were included as a control. Results: There were no significant differences between MT and CT groups regarding baseline sepsis workup. However, total leucocytic count, absolute neutrophil count, and C-reactive protein were significantly higher and platelets were significantly lower in CT compared to MT after 72 h. MDA was doubled in CT while reduced in MT 72 h after intervention (p = 0.000). Mortality was significantly lower in MT. No side effects following melatonin administration were reported. Conclusion:Melatonin is effective and safe adjuvant for treatment of NS that improves clinical and laboratory outcomes.

PurposeThis study aimed to assess whether different anesthetic techniques and oxytocin use applied during delivery affect transcutaneous bilirubin levels during the first 24 hours in neonates.MethodsA total of 1,044 neonates delivered by either caesarian section (C/S) or normal vaginal delivery (NVD) were included in the study. They were classified into 5 groups as follows: group 1: born by C/S using general anesthesia, group 2: C/S using spinal anaesthesia, group 3: C/S using general anesthesia after failed spinal block, group 4: by NVD without anesthesia, and group 5: oxytocin-induced vaginal delivery without anesthesia. Transcutaneous total bilirubin levels (TBLs) were measured during the first 24 hours and on the fifth and eighth days of life and the levels in different groups were compared.ResultsThe TBLs were significantly higher in neonates delivered by C/S using general anesthesia rather than spinal anesthesia (P<0.001), and both groups had higher levels than those born by NVD without anesthesia (P≤0.001). However, the group receiving general anesthesia after failed spinal block was found to have the highest bilirubin level. Moreover, TBLs were significantly higher with the use of oxytocin (P≤0.001).ConclusionsC/S and general anesthesia adversely affect the bilirubin levels in neonates, and the use of oxytocin during vaginal delivery also increases TBLs in neonates.

Because ghrelin is one of the key hormones in regulating feeding behavior and caloric status, it was suggested that ghrelin behavior might be closely associated with malnutrition state of patients with chronic liver disease (CLD). Thus, we aimed to assess serum ghrelin levels in children with CLD and its relation to anthropometric parameters and severity of CLD. Forty CLD patients were studied in comparison to 40 controls. All subjects were subjected to history, anthropometric, and laboratory assessment of liver functions and serum acylated ghrelin. Ghrelin was higher in patients than controls being higher with progress of Child's grade and with deterioration of liver functions. Hyperghrelinemia was detected in 62.5% of cases. Ghrelin correlated negatively with body mass index standard deviation score (BMISDS ( = −0.95, < 0.001)), triceps skin fold thickness (TSFT ( = −0.88, < 0.001)), and subscapular skin fold thickness (SSFT ( = 0.83, < 0.001)) percentiles. In conclusion, hyperghrelinemia may represent a compensatory mechanism trying to overcome malnutrition state complicating CLD and can be used as a parameter for early detection and assessment of the severity of malnutrition in children with CLD.

Dyslipidemia and HI were frequent findings in patients with CLD, which worsened with increased severity of CLD.
