Sodium intake affects urinary albumin excretion especially in overweight subjects.
OBJECTIVES: To examine the relationship between sodium intake and urinary albumin excretion, being an established risk marker for later cardiovascular morbidity and mortality. DESIGN: Cross-sectional cohort study using linear regression analysis. Setting. University hospital outpatient clinic. SUBJECTS: A cohort drawn from the general population, consisting of 7850 subjects 28-75 years of age, all inhabitants of the city of Groningen, the Netherlands. The cohort is enriched for the presence of subjects with elevated urinary albumin concentration. RESULTS: The results show a positive relationship between dietary sodium intake and urinary albumin excretion. The association was independent of other cardiovascular risk factors (such as sex, age, blood pressure, body mass index (BMI), waist-to-hip ratio, serum cholesterol, plasma glucose and smoking) and other food constituents (calcium, potassium and protein). The relationship between sodium intake and urinary albumin excretion was steeper in subjects with a higher BMI compared with a lower BMI. CONCLUSIONS: Sodium intake is positively related to urinary albumin excretion. This relation is more pronounced in subjects with a higher BMI. These results suggest that high sodium intake may unfavourably influences cardiovascular prognosis especially in overweight and obese subjects.

The reliability of different formulae to predict creatinine clearance.
OBJECTIVES: Creatinine clearance (CCR) is a commonly used tool to measure glomerular filtration rate (GFR) in clinical practice. This tool requires collection of 24-h urine, which is quite bothersome. Several different formulae have been used to estimate GFR using plasma creatinine and other easy formulae to obtain biometrical data. We examined 10 formulae and compared them with actually measured CCR in a large sample of the general population. DESIGN: Cross-sectional cohort study. SETTING: University hospital outpatient clinic, a population based study. SUBJECTS: A total of 8592 inhabitants of the city of Groningen, 28-75 years of age. The cohort is enriched for microalbuminuria. RESULTS: In general, the formulae did not give an accurate estimation of CCR, particularly not in male and in obese subjects. Six formulae, including the Cockcroft-Gault gave a fairly good estimation of CCR in the overall population and in subgroups of specific gender, body mass index and age. All formulae however, gave an underestimation of the measured CCR in higher ranges of CCR and an overestimation in the lower ranges. Moreover, the age-related decline of CCR is hard to approximate with a formula. CONCLUSIONS: We conclude that formulae to estimate CCR in the general population, although giving a fairly good estimate of mean CCR, do not offer reliable data on CCR in the upper and lower ranges and do not adequately estimate the age-related decline in CCR.

[Signs of miliary tuberculosis: which diagnostic tests and when to treat?].
Three patients, men aged 21, 57 and 53 years, presented with variable non-specific symptoms such as general malaise, weight loss, elevated temperature, abdominal pain, cough, pulmonary crepitations and elevated liver enzymes. Diffuse fine nodular infiltration was seen on chest radiography in the last two cases. The first patient refused to be tentatively treated with tuberculostatics and died. Mycobacterium tuberculosis complex grew on Löwenstein medium a week later. The two other patients received tuberculostatic treatment. The second patient recovered, while the third patient suffered a cerebrovascular accident on top of emaciation and respiratory insufficiency and died. In the Netherlands, currently more than one hundred patients with tuberculosis disease die each year. The disease is mostly seen in people from the high-risk groups for tuberculosis such as asylum seekers and immigrants. Even after extensive diagnostic procedures it can be difficult to obtain rapid bacteriological confirmation. When miliary tuberculosis is suspected it is important to carry out the complete range of tests (Ziehl Neelsen microscopy, PCR, Löwenstein cultivation) and to start therapy immediately and not to await the results of the diagnostic tests. However, in many cases this may still be too late, with an estimated mortality of 20%.

Obesity and target organ damage: the kidney.
Obesity is a risk marker for progressive renal function loss in patients with known renal disease. There is, however, increasing evidence that obesity may also damage the kidney in otherwise healthy subjects. There appears to be an intriguing parallel between the renal effects of obesity and those of diabetes. First, an increased renal blood flow and glomerular filtration rate has been described in obesity and, second, microalbuminuria is found to be related to obesity. These two events are known to predict future loss of renal function in diabetes. The mechanism responsible for the renal damage in obesity has not been established but there is evidence suggesting that this might be related to both hormonal changes as well as low-grade inflammation.

[Tuberculosis of the pancreas in a HIV-seropositive patient].
A 34-year-old man from Nigeria who had resided permanently in the Netherlands for five years had experienced fever, upper abdominal pain and weight loss for several months. He did not give the impression of being ill. A CT scan gave cause to suspect pancreatitis. An HIV test gave a positive result. Puncture of the accumulated fluid around the pancreas led to the diagnosis 'tuberculosis' (infection by Mycobacterium tuberculosis). Once the patient had made a good recovery with antituberculosis therapy, antiretroviral therapy was initiated, whereupon the number of CD4+ cells in the blood increased. Extrapulmonal tuberculosis is not unusual in HIV seropositive patients from countries with a high prevalence of tuberculosis. However, in such patients isolated tuberculosis of the pancreas is unusual and has not previously been described in the Netherlands. The diagnosis can be established following a CT guided puncture; tuberculosis is instantly suspected if the Ziehl-Neelsen stains are positive and the diagnosis can then be confirmed by a polymerase chain reaction (PCR) analysis and by culturing. Anti-retroviral therapy is withheld until response to anti-tuberculosis treatment is satisfactory.
