Olmesartan-induced enteropathy consists a syndrome that mimics celiac disease both clinically and histologically. Cases of this entity have sporadically been reported since 2012 and are usually ...characterized by severe diarrhea and malabsorption, followed by significant weight loss.
Herein, we report an uncommon case of this syndrome, where weight loss preceded several months the onset of gastrointestinal symptoms.
Physicians should be aware of unexplained weight loss in patients taking olmesartan, as prompt discontinuation of the drug may prevent the deleterious consequences of malabsorption.
Familial hypercholesterolemia (FH) carries a high risk of atherosclerotic cardiovascular disease (ASCVD). As the population ages, the age-related influence on clinical characteristics and outcomes ...becomes increasingly pertinent. This cross-sectional analysis from the HELLAS-FH registry aims to explore potential differences in clinical characteristics, treatment, ASCVD, and goal achievement between those younger and older than 65 years with FH.
A total of 2273 adults with heterozygous FH (51.4% males) were studied. Elderly FH patients (
= 349) had a higher prevalence of ASCVD risk factors, such as hypertension (52.1% vs. 20.9%,
< 0.05) and type 2 diabetes (16.9% vs. 6.0%,
< 0.05), compared to younger patients (
= 1924). They also had a higher prevalence of established ASCVD (38.4% vs. 23.1%,
< 0.001), particularly CAD (33.0% vs. 20.2%,
< 0.001), even after adjusting for major ASCVD risk factors. Elderly patients were more frequently and intensively receiving lipid-lowering treatment than younger ones. Although post-treatment LDL-C levels were lower in elderly than younger patients (125 vs. 146 mg/dL,
< 0.05), both groups had similar attainment of the LDL-C target (3.7% vs. 3.0%).
Elderly FH patients have a higher prevalence of ASCVD, particularly CAD. Despite more aggressive treatment, the achievement of LDL-C targets remains very poor. These results emphasize the importance of early FH diagnosis and treatment in reducing ASCVD.
Hyponatremia (serum sodium level less than 134 mmol/L) is a common electrolyte disturbance. Its high prevalence and potential neurologic sequelae make a logical and rigorous differential diagnosis ...mandatory before any therapeutic intervention. A history of concurrent illness and medication use as well as the assessment of extracellular volume status on physical examination may provide useful clues as to the pathogenesis of hyponatremia. Measurement of the effective serum tonicity (serum osmolality less serum urea level) is the first step in the laboratory evaluation. In patients with normal or elevated effective serum osmolality (280 mOsm/kg or greater), pseudohyponatremia should be excluded. In the hypo-osmolar state (serum osmolality less than 280 mOsm/kg), urine osmolality is used to determine whether water excretion is normal or impaired. A urine osmolality value of less than 100 mOsm/kg indicates complete and appropriate suppression of antidiuretic hormone secretion. A urine sodium level less than 20 mmol/L is indicative of hypovolemia, whereas a level greater than 40 mmol/L is suggestive of the syndrome of inappropriate antidiuretic hormone secretion. Levels of hormones (thyroid-stimulating hormone and cortisol) and arterial blood gases should be determined in difficult cases of hyponatremia.

Diabetic patients frequently develop a constellation of electrolyte disorders. These disturbances are particularly common in decompensated diabetics, especially in the context of diabetic ...ketoacidosis or nonketotic hyperglycemic hyperosmolar syndrome. These patients are markedly potassium-, magnesium- and phosphate-depleted. Diabetes mellitus (DM) is linked to both hypo- and hyper-natremia reflecting the coexistence of hyperglycemia-related mechanisms, which tend to change serum sodium to opposite directions. The most important causal factor of chronic hyperkalemia in diabetic individuals is the syndrome of hyporeninemic hypoaldosteronism. Impaired renal function, potassium-sparing drugs, hypertonicity and insulin deficiency are also involved in the development of hyperkalemia. This article provides an overview of the electrolyte disturbances occurring in DM and describes the underlying mechanisms. This insight should pave the way for pathophysiology-directed therapy, thus contributing to the avoidance of the several deleterious effects associated with electrolyte disorders and their treatment.
Metabolic acidosis is a frequently encountered acid-base disturbance in hospitalized patients that occasionally develops in the course of treatment with medications used in everyday clinical ...practice, including propylene glycol-containing drugs (lorazepam, diazepam, etomidate, pentobarbital). Disruption of enterohepatic circulation with activated charcoal is a common practice for several intoxications, including mushroom poisoning. Herein, we present a patient who was hospitalized due to mushroom intoxication and developed severe metabolic acidosis as a treatment side effect rather than from the mushroom poisoning. Τo the best of our knowledge, this is the first report on propylene glycol-containing activated charcoal-induced metabolic acidosis.
Object Electrolyte abnormalities are frequently observed in patients with hyponatremia. The aim of this study was to determine the incidence of various electrolyte abnormalities encountered in ...hyponatremic patients admitted to an internal medicine clinic, as well as to investigate the possible pathogenetic mechanisms responsible for these abnormalities. Patients and Methods We prospectively studied 204 adult patients who either on admission to our clinic or during their hospitalization were found to have hyponatremia. Results Ninety-two patients (45.5%) had at least one additional electrolyte abnormality. Hypophosphatemia was the most frequent electrolyte disorder observed (35 patients, 17%). Hypokalemia was seen in 32 patients (15.8%), hypomagnesemia in 31 patients (15.2%) and hyperkalemia in 12 patients (5.9%). Moreover, 5 patients (2.5%) had hyperphosphatemia, 4 patients (1.9%) exhibited hypermagnesemia, 3 patients (1.4%) had hypercalcemia, and 6 patients (2.9%) had true hypocalcemia. There were no statistically significant differences regarding the incidence of these electrolyte abnormalities (as a whole) between the main subgroups of hyponatremic patients (diuretic-induced, syndrome of inappropriate antidiuretic hormone, hypovolemia-induced and edematous state-related). However, hypokalemia and hypomagnesemia were more frequently observed in patients with diuretic-induced hyponatremia, while hyperkalemia was more frequently seen in edematous state-related hyponatremia. Conclusions Additional electrolyte abnormalities are frequently encountered in patients with hyponatremia of any origin admitted to an internal medicine clinic.
Decreased serum sodium concentration is a rather frequent electrolyte disorder in the elderly population because of the presence of factors contributing to increased antidiuretic hormone, the ...frequent prescription of drugs associated with hyponatremia and also because of other mechanisms such as the "tea and toast" syndrome. The aim of this review is to present certain challenges in the evaluation and treatment of hyponatremia in the elderly population and provide practical solutions. Hyponatremia in elderly subjects is mainly caused by drugs (more frequently thiazides and antidepressants), the syndrome of inappropriate antidiuretic hormone secretion (SIAD) or endocrinopathies; however, hyponatremia is multifactorial in a significant proportion of patients. Special attention is needed in the elderly population to exclude endocrinopathies as a cause of hyponatremia before establishing the diagnosis of SIAD, which then requires a stepped diagnostic approach to reveal its underlying cause. The treatment of hyponatremia depends on the type of hyponatremia. Special attention is also needed to correct serum sodium levels at the appropriate rate, especially in chronic hyponatremia, in order to avoid the osmotic demyelination syndrome. In conclusion, both the evaluation and the treatment of hyponatremia pose many challenges in the elderly population.
Background: Elevated uric acid (UA) is a recognized risk factor for chronic kidney disease (CKD). This study aimed to investigate whether this association exists in dyslipidemic patients receiving ...multifactorial treatment.
Methods: An observational study conducted in Greece including 1,269 dyslipidemic individuals followed-up in a lipid clinic for ≥3 years. Estimated glomerular filtration rate (eGFR) was calculated by CKD-EPI equation and CKD was defined as ≤60 mL/min/1.73 m

. The correlation was assessed between UA levels and the CKD risk after adjusting for potential confounding factors, after defining the following UA quartiles: Q1: < 4, Q2: 4-5, Q3: 5-6, and Q4: > 6 mg/dL.
Results: After excluding patients with baseline eGFR <60 mL/min/1.73 m

, gout and those taking UA-lowering drugs, 1,095 individuals were eligible; of those, 91% and 69% were treated with statins and anti-hypertensive drugs, respectively. During their follow-up (6 years; IQR = 4-10), 11.9% of the subjects developed CKD, whereas the median annual eGFR decline was 0.69 mL/min/1.73 m
2
(IQR = 0.45-2.33). Multivariate analysis showed that baseline UA levels (HR = 1.26; 95% CI = 1.09-1.45, p = .001), female gender (HR = 1.74; 95% CI = 1.14-2.65, p = .01), age (HR = 1.10; 95% CI = 1.07-1.12, p < .001), diabetes (HR = 1.67; 95% CI = 1.05-2.65, p = .03), cardiovascular disease (HR = 1.62; 95% CI = 1.02-2.58, p = .04), decreased baseline renal function (eGFR <90 mL/min/1.73 m
2
) (HR = 2.38; 95% CI = 1.14-4.81, p = .02), and low-density lipoprotein cholesterol reduction (HR = 0.995; 95% CI = 0.991-0.998, p = .01) were associated with incident CKD. Additionally, patients with UA ≥6 mg/dL exhibited a higher risk of incident CKD compared with those in the lowest UA quartile (HR = 2.01; 95% CI = 1.11-3.65, p = .02).
Conclusion: Higher UA levels are correlated with a higher risk of incident CKD in dyslipidemic individuals taking multifactorial treatment.
