“…Although drinking coffee prepared and served in lead-glazed ceramic ware is common in Mexico, the association between coffee drinking and increased lead is independent of the effect of use of lead-glazed ceramic ware on PbB, as noted in the multiple regression analyses (Table 3). Caffeine intake is associated with increased calcium excretion in women (32,33), likely due to its effect on renal reabsorption (34). There are no data reported in the literature regarding the effect of caffeine on lead excretion.…”

The first step in modli lead kinetics during pregnancy includes a description of sequential matenal blood lead (PbB) Cross-sectional studies of groups of women at different stages of pregnancy present conflicting results (1-3), and the design is inadequate to study serial changes of lead during pregnancy. Case studies with serial measurements of PbB in pregnant women are interesting (4-6), but these are usually of women suffering frank lead intoxication.The only detailed work prospectively studying PbB in pregnant women is that of Barltrop (7) A priori exclusion criteria for the study were: 1) younger than 15, older than 42; 2) active diabetes, German measles, hepatitis, or toxoplasmosis, as determined by laboratory test, 3) habitual use of alcohol or drugs, 4) use of prescription medications, 5) hypertension controlled with medication, 6) active psychosis. Women not excluded by these criteria were informed of the purpose of the study and the procedures involved. They read, or were read, a statement of informed consent approved by the institutional review board, and signed it.A total of 532 women passed the exclusion criteria and were enrolled in the study. Of this total, 30 never arrived at the project office for their first or following appointments. One case developed hypoglycemia and 27 developed conditions described by the above exclusion criteria during their pregnancy; 22 spontaneously aborted, and 16 were stillbirths. We will report these data elsewhere. The exclusion of these subjects left 436 participants.Some of the remaining women gave birth to babies meeting the following a priori exclusion criteria, and these 22 pregnancies were also removed from the present data set: 1) birth weight under 2000 g, 2) gestation age under 36 weeks, 3) 5-min Apgar score under 6, 4) multiple birth, and 5) major congenital anomaly. An additional 41 babies suffered from hyperbilirubinemia, high lead level [one baby was born with a cord level of 69 pg/dl (3.33 pmol/l); see Rothenberg et al. (6) for description of this case], minor congenital anomaly, severe infection, birth trauma, asphyxia, respiratory difficulty, or early infant death, and these cases were also excluded from the data set. Table 1 summarizes data on 159 patients who were excluded or who dropped out of the study and compares them to 373 patients retained in the study. Excluded patients were significantly older, had more pregnancies and abortions, and gave birth to lower birth-weight and lower

“…The mechanism related to this nephrotoxic effect of caffeine could be ascribed to its capacity to block renal adenosine receptors, which may augment angiotensin II-induced glomerular hypertension [148]. Caffeine was also found to be associated with reduced incidence of kidney stones [149][150][151], even though it induces increased calcium excretion [151,152]. Probably the increased urine output and consequent urine dilution associated with caffeine consumption might contribute to a lower risk of developing kidney stones [151].…”

Abstract:Chronic kidney disease (CKD) affects worldwide 8-16% of the population. In developed countries, the most important risk factors for CKD are diabetes, hypertension and obesity, calling into question the importance of educating and acting on lifestyles and nutrition. A balanced nutrition and supplementation can indeed support the maintenance of a general health status, including preservation of renal function, and help to manage and curb the main risk factors for renal damage. While the concepts of protein and salt restriction in nephrology are historically acknowledged, the role of some nutrients on renal health and the importance of nutrition as a preventative measure for renal care are less known.In this review, we provide an overview of the demonstrated and potential actions of some selected nutrients, nutraceuticals and xenobiotics on renal health and function. The effects on kidney of fibres, proteins, fatty acids, curcumin, steviol glycosides, green tea, coffee, nitrates, nitrites, and alcohol, both direct and indirect, in CKD and non-CKD condition, are reviewed here. In a view of a functional and personalized nutrition, understanding the renal and systemic effects of dietary components is essential since many chronic conditions and CKD are related to systemic dysfunctions such as chronic low-grade inflammation.

“…Saturation of albumin by caffeine or theophylline interferes with plasma magnesium and calcium corrections [95,96] that are related to plasma albumin contents ( Figure 3). Caffeine excess with aging is relevant to magnesium deficiency [97][98][99] and relevant to neuron calcium dyshomeostasis [17,100] that is connected to SCN dysynchrony critical to the maintainance of circadian rhythms [7]. Disturbances in neurons by caffeine involve neuron calcium disturbances that involve the adenosine receptors, synapses and neuron networks [101,102] with detrimental effects on the central nervous system with irreversible T3D [36,37].…”
