ABSTRACT A case is reported of intermittent hypercalcaemia, hypophosphataemia and severe skeletal rarefaction with cystic changes. An occult calcium malabsorption was found. Fat, triolein and iron absorption and radiological examinations were normal. There was gross intestinal mucosal atrophy. She was shown to be in a state of negative calcium balance and this was reversed by vitamin D. A gluten-free diet also improved calcium absorption. It is postulated that the patient had severe secondary hyperparathyroidism as the skeleton reverted to normal after six months of medical treatment.

Abstract Objectives To investigate whether the perioperatively combined application of dexamethasone and furosemide could alleviate the inflammation in patients undergoing percutaneous nephrolithotomy (PCNL). Patients and methods 147 patients undergoing PCNL between November 2018 and October 2019 were enrolled in the study. 77 patients accepted a single dose of dexamethasone and furosemide administration (EXP group, n = 77), and 70 patients did not (CON group, n = 70). Demographic and perioperative data, inflammatory markers including interleukin-6 (IL-6) and procalcitonin (PCT), and clinical outcomes were compared between the two groups. Results Compared with the CON group, the incidence rate of urosepsis of the EXP group were significantly lower (11.69% vs. 24.29%, p = 0.046). 3 patients developed severe urosepsis in the EXP group, while 5 patients developed severe urosepsis in the CON group. Compared with those in the CON group, the patients with postoperative urosepsis in the EXP group showed lower serum levels of IL-6 at postoperative hour two (p = 0.045) and at postoperative day one (p = 0.031) and lower serum levels of PCT at postoperative day one (p = 0.015). There was a better clinical outcome of a shorter postoperative hospital stay (p = 0.015) in patients with postoperative urosepsis in the EXP group than in those in the CON group. Conclusion The perioperatively combined application of dexamethasone and furosemide was beneficial for alleviating postoperative inflammatory reaction and caused a better clinical outcome of a shorter postoperative hospital stay.

Abstract Background and Aims Acute kidney injury (AKI) occurring after diuretic treatment initiation for acute heart failure (AHF) is a common phenomenon, with an incidence estimated between 20 and 50% of AHF hospitalizations. Previous studies found that persistent AKI is associated with poor prognosis. Treatment-induced hemoconcentration is associated with improved prognosis, but several definitions previously used are not suited for clinical practice. Transient AKI, with or without hemoconcentration, is of unsettled prognosis. We aim to determine the independent prognostic value of transient AKI, persistent AKI and hemoconcentration in the context of AHF hospitalization, using practical definitions. Method Data were obtained from the Greater Paris University Hospitals (GPUH) Clinical Data Warehouse. Patients hospitalized for AHF in various GPUH units were included. AHF hospitalization was defined as hospitalization with at least one AHF ICD-10 code and at least one recorded furosemide administration. Bumetanide is rarely used in GPUH hospitals hence it was not considered. AKI in a period of 14 days following first furosemide administration was defined based on KDIGO guidelines. Hemoconcentration was defined as an increase in serum proteins ≥ 5 g/l during the same period. Multivariate logistic regression was performed to determine which characteristics were predictive of AKI. Cox regression of 100 days all-cause mortality using multiple confounders was performed to determine the prognostic value of transient AKI (< 14 days), persistent AKI (≥ 14 days) and hemoconcentration. Patients with AKI upon hospital entry were excluded from regression analyses. AKI and hemoconcentration were treated as time-dependent covariates to adjust for immortality bias. Results Five hundred seventy nine patients were included. Among them, 529 had no AKI upon hospital entry and 513 had at least one recorded serum proteins and creatinine value following furosemide initiation. Median follow-up was 114 days. AKI in a period of 14 days following furosemide initiation occurred in 234 patients (40.4%). At baseline, patients in the AKI group more frequently suffered from chronic kidney disease or presented with clinical and echocardiographic signs of right heart failure. Independent predictors of AKI were arterial hypertension upon furosemide initiation (adjusted OR 1.86 [1.08 – 3.22]), elevated serum creatinine upon furosemide initiation (adjusted OR 1.07 [1.01 – 1.14] per 10 µmol/l increase) and initial intravenous administration of furosemide (adjusted OR 2.42 [1.39 – 4.29]). Death during follow-up occurred in 35% of patients in the AKI group compared to 21% in the non-AKI group (p < 0.001). In multivariate analysis, persistent AKI was independently associated with increased mortality in a period of 100 days following furosemide initiation (adjusted HR 2.31 [1.07 – 4.99]). Transient AKI was not significantly associated with mortality (adjusted HR 0.64 [0.34 – 1.19]). Hemoconcentration was independently associated with decreased mortality (adjusted HR 0.46 [0.27 – 0.79]). Conclusion After furosemide initiation during hospitalization for AHF, persistent AKI (≥ 14 days) was independently associated with increased 100 days mortality. Hemoconcentration, using a definition suited for clinical practice (≥ 5 g/l increase in serum proteins), was independently associated with decreased 100 days mortality. No significant association was found between mortality and transient AKI (< 14 days). Those findings show that laboratory tests at a limited cost – serum proteins and creatinine – are helpful to evaluate treatment response and mortality risk during AHF. Prospective randomized controlled trials are needed to establish diuretic strategies based on both AKI and hemoconcentration.

Heart Performance

The prevalence of cardiovascular diseases dramatically increases with age, therefore striving to maintain a physiological heart function became particularly important. We aimed to study the voluntary exercise evoked cardioprotective effects in aged male and female rats, from genetic alterations to changes in heart performance. We divided 20-month-old female and male Wistar rats to control and running groups. After the 12-week-long experimental period, echocardiographic measurements were performed. Afterwards, hearts were either removed for biochemical measurements or mounted into a Langendorff-perfusion system to detect infarct size. The following genes and their proteins were analyzed from heart: catechol-O-methyltransferase (Comt), endothelin-1 (Esm1), Purkinje cell protein-4 (Pcp4), and osteoglycin (Ogn). Recreational exercise caused functional improvements; however, changes were more prominent in males. Cardiac expression of Comt and Ogn were reduced as a result of exercise in aged males, while Pcp4 and Esm1 showed a marked overexpression, along with a markedly improved diastolic function. The key result of this study is that exercise enhanced the expression of the Pcp4 gene and protein, a recently described regulator of calcium balance in cardiomyocytes, and suppressed Comt and Ogn gene expression, that has been associated with impaired cardiac function. In addition, as a result of exercise, a significant improvement was observed in the size of infarct elicited by left anterior descending coronary artery occlusion. Our results clearly show that age and sex-dependent changes were both apparent in key proteins linked to cardiovascular physiology. Exercise-moderated fundamental genetic alterations may have contributed to the functional adaptation of the heart.
