Testosterone deficiency is one of the complications found in male patients with chronic kidney disease (CKD) and may participate in the pathogenesis of osteoporosis, sarcopenia, anemia, impotence, infertility, and other comorbidities observed in these patients. The aim of the study was the evaluation of the frequency of testosterone deficiency in male patients with CKD on maintenance hemodialysis (HD).

In 79 male HD patients serum total (TT) and free (FT) testosterone, C-reactive protein (CRP) and interleukin - 6 (IL - 6) serum concentrations were assessed before HD procedure. Patients were divided into three subgroups based on age categories 19 - 39 years (18 patients), 40 - 59 years (34 patients) and ≥60 years (27 patients), respectively. TT insufficiency and deficiency were diagnosed when serum TT concentration was below 4.0 ng/ml and 2.9 ng/ml, respectively. FT deficiency was diagnosed in patients with serum FT concentration below 8.9, 6.6 and 4.9 pg/ml in above mentioned age subgroups, respectively.
with chronic kidney disease treated with HD. 2. In HD patients serum testosterone concentration decreases with age. 3. Chronic inflammation may participate in pathogenesis of testosterone deficiency in haemodialysis patients.
Orexin-A is a neuropeptide synthesized in the lateral hypothalamus. Orexin-A immunoreactive fibres overlap distribution with GnRH neurons. In adult rats, orexin A is known to affect LH secretion via GnRH release modulation. Because data concerning the impact of orexin-A on the hypothalamo-pituitary axis activity are limited, we focused on the involvement of orexin-A and receptors of NPY in the modulation of LH release and LH subunit b (Lhb) mRNA expression in prepubertal female rats.

Forty immature female Wistar rats were divided into 4 groups and received 2 intracerebroventricular (icv) microinjections of 1 - artificial cerebrospinal fluid (CSF) (controls); 2 - CSF followed by orexin A; 3 - selective NPY receptor antagonist (BIBP) followed by CSF; 4 - BIBP followed by orexin A. One hour after the last microinjection, all rats were decapitated. Trunk blood was collected, and serum was stored at -20°C for the LH RIA examination. The adenohypophysis was immediately excised, flash-frozen, and kept at -80°C fy did not reverse the suppressive effect of exogenous orexin-A, it might be suggested that NPY and orexin A systems can operate independently to affect gonadotropin activity in the anterior pituitary of the immature female rats.
Orexin-A exerts a down-regulatory effect on LH synthesis and release in immature female rats. Considering that Y1R-oriented down-regulation of endogenous NPY activity did not reverse the suppressive effect of exogenous orexin-A, it might be suggested that NPY and orexin A systems can operate independently to affect gonadotropin activity in the anterior pituitary of the immature female rats.
Final adult height (FAH) in patients with congenital adrenal hyperplasia (CAH) is often lower than predicted adult height (PAH) using Bayley-Pinneau (B&P). https://www.selleckchem.com/products/vvd-214.html The aim of the current work was to test the validity of B&P in predicting FAH from a bone age (BA) performed at onset of puberty.

This was a retrospective longitudinal observational convenience single-center study. The study included 54 patients (male and female) with classic CAH whether salt-wasting (SW) or simple virilising (SV) who had reached FAH. Results of auxological measurements and hormonal data around the time of puberty were retrieved from files. Predicted adult height (PAH) was calculated from a BA taken at onset of puberty and compared with FAH.

The median PAH SDS at the onset of puberty (-1.5) was significantly greater than median FAH SDS (-2.2) (p<0.001). The median target height SDS (-0.8) was significantly higher than median FAH SDS (-2.2) (p<0.001). FAH and FAH SDS were significantly worse in females (150.36 ± 7.23; -2.05+1.13) than their male counterparts (162.86 ± 3.30; -1.53+0.51) (p value < 0.001; 0.048). In patients with good control, there was no difference between PAH SDS (-1.7) and FAH SDS (-1.5) (p value=0.37). In patients with poor control (over or under-treated) FAH SDS (-2.1) was significantly lower than PAH SDS (-1.4) (P value<0.001).

B&P method was able to accurately predict FAH in children with classic CAH who were medically well controlled (based on 17-hydroxyprogesterone levels) but overestimated it by a significant 0.7SD in poorly-controlled patients.

It is an autosomal recessive disorder, mostly involving in the Wolfram syndrome 1 gene. The phenotypic pleiomorphism, rarity and molecular complexity complicate the follow-up of these patients.
We aimed to describe the clinical characteristics and the follow up of 11 patients with this disorder. We retrospectively analyzed all WFS patients diagnosed between 1990 and 2020 in the Centro Hospitalar São João, a tertiary hospital in Northern Portugal.

Eleven patients were included. Four patients have all 4 components of DIDMOAD. The presentation was diabetes mellitus (DM) in nine patients, Optic Atrophy (OA) in another patient, and Diabetes Insipidus (DI) in another one. The median age of DM and OA diagnosis was 6 and 14 years, respectively. Nine patients had diabetes mellitus, and the other two patients had impaired glucose tolerance. All patients had OA. Four patients presented DI, all of them diagnosed in adolescence. Four patients had hearing impairment, five had urological abnormalities, and five had neurologic disorders and eight had psychiatry disorders. Eight patients had a broad spectrum of recessive mutations in WFS1.

In conclusion, the information obtained in this study can facilitate further research in an attempt to improve prevention strategies for this devastating disease.
