Comparison of C-reactive protein and high-sensitivity C-reactive protein levels in patients on hemodialysis.

Chronic inflammation is highly prevalent in patients on hemodialysis (HD), as evidenced by increased levels of C-reactive protein (CRP). We compared CRP to high-sensitivity C-reactive protein (hs-CRP) to determine whether it has any clinical implications and prognostic significance in terms of mortality. CRP was measured using a standard immunoturbidometric assay on the COBAS® INTEGRA system and hs-CRP was measured using the Dade Behring on the Konelab Nephelometer in 50 patients on HD.

[Variations of troponin T in chronic hemodialysis patients: study of 52 cases].

Background: Patients with severe renal dysfunction have unexplained elevated serum concentrations of cardiac troponin T.

Aim: Study the frequency of elevated cTnT in hemodialysis patients and investigated whether cTnT is elevated.

Methods: The patient population consisted of 52 patients on maintenance hemodialysis and 20 healthy subjects.

[Cystine lithiasis: retrospective study about 25 cases].

Introduction: cystinuria is a severe form of renal which is exposed the patient at multiple recurrent.

Objective: Report and identify the clinical and biochemical characteristic of cystinuria in Tunisian region.

Methods: It is a study of 25 cases of cystinuria, concerning at 16 adults and 9 children from 1995 to 2006.

[Biochemical markers of bone remodeling: recent data of their applications in managing postmenopausal osteoporosis].

The recent development of new biochemical markers has considerably improved the non invasive exploration of bone turnover. Currently, the most sensitive markers to access bone formation are osteocalcin, bone alkaline phosphatase and N-terminal propeptide of type I procollagen. Blood or urinary immunoassays of pyridinoline, deoxy-pyridinoline and terminal telopeptides type I of collagen are currently the best indices to evaluate the bone resorption.

[Variation of biochemical parameters of the first morning urine during month of Ramadan].

The purpose of this study is to evaluate the effect of fluid and diet restriction in fasting on biochemical factors of stone formation. Our study concernes 90 patients divided in three groups: healthy fasting patient (GI), healthy non fasting patient (G2) and non fasting patient with calcium lithiasis (G3). The promotors (oxalate, calcium, uric acid, phosphates) and inhibitors (citrate, magnesium) are statistically significant between G1, G2 and G3, G2.
