RESUMO
Chronic kidney disease is associated with an increased risk for cardiovascular and bleeding events. Data regarding the effectiveness and risks of aspirin therapy for primary prevention in the high-risk group of patients with chronic kidney disease are scant and controversial. This retrospective study included patients with chronic kidney disease. Participants were divided according to aspirin use. Outcomes included non-fatal cardiovascular events, major bleeding events and all-cause mortality. Among 10,303 patients, 2169 met the inclusion criteria and 1818 were included after 1:1 propensity-score matching. Our final cohort included patients with mean age of 73.4 ± 11.6 years, estimated glomerular filtration rate of 31.5 ± 10.5 ml/min/1.73m2 with follow up of 4.9 ± 1.5 years. There were no significant differences in all-cause mortality and bleeding events (odds ratio = 1.03, confidence interval [0.62, 1.84], p = .58 and odds ratio = 1.09, confidence interval [0.65, 1.72], p = .87 respectively). The incidence of cardiovascular events was higher in aspirin users versus non-users on univariate analysis (p < 0.01) and was comparable after controlling for possible risk-factors (OR = 1.05, CI [0.61, 3.14], p = .85). Chronic aspirin use for primary prevention of cardiovascular disease was not associated with lower mortality, cardiovascular events or increased bleeding among patients with chronic kidney disease. Those results were unexpected and should prompt further research in this field.

OBJECTIVE: Congenital MPHD is a rare condition caused by mutations in pituitary transcription factors genes: PROP1, POU1F1 (PIT1), HESX1, LHX3, LHX4. DESIGN: We evaluated in a retrospective study the effects on growth and development in 29 patients with congenital MPHD (cMPHD), during hGH replacement therapy alone and combined with sex hormones. Twenty nine patients with cMPHD were included and diagnosed, treated and followed in our clinic from diagnosis to adult age. Measurements on growth and development were taken by the same medical team. RESULTS: Mean birth weight of 21/29 neonates was 3126 ± 536 g. Mean birth length of 7/29 neonates was 48.7 ± 2 cm. Neuromotor development was normal or slightly delayed. Mean age at referral was 9.5 ± 7 years (m), 6.7 ± 3.5 years (f) (p=0.17). Height (SDS) before treatment was -2.8 ± 1.0 (m), -2.8 ± 1.0 (f) (p=0.99). Mean age at initiation of hGH treatment was 9.9 ± 6.7 years (m), 10.3 ± 4.2 years (f) (p=0.85). Mean age at initiation of sex hormone treatment was 17.0 ± 3.5 years (m), 17.1 ± 2.3 years (f) (p=0.88). Penile and testicular sizes were below normal before and after treatment. Head circumference (SD) was -1.9 ± 0.9 before and -0.6 ± 1.8 at end of treatment (p<0.001). Adult height (SDS) reached -1.1 ± 0.6 (p<0.001) for both males and females. CONCLUSION: Despite the multiple pituitary hormone deficiencies including hGH, children with congenital MPHD present with a better auxological development than children with congenital IGHD or congenital IGF-1 deficiency. These findings may be due to irregular and incomplete hormone deficiencies increasing with progressive age and late initiation of puberty.
