A girl presented with small stature, obesity, tapetoretinal degeneration, deafness, psychomotor regression, seizures, acanthosis nigricans, hepatomegaly, and chronic tubulointerstitial nephropathy. She died at age ten with renal insufficiency and uncontrolled seizures. Histochemistry showed lipid storage in hepatocytes, histiocytes, smooth muscles and, to a much lesser extent, kidney tubules and cortical neurons. The liver had increased cholesterol esters (5-fold) and triacylglycerols (8-fold), and decreased phospholipids (50%). Methyllumbelliferyl-oleate, oleylcholestrol, trioleylglycerol, and tripalmitylglycerol lipase activities were markedly reduced in the liver, in the range found in Wolman's disease. In cirrhotic fatty livers these activities ranged from 7-87% of the normal mean. The patient's brain had limited neutral lipid storage and normal methyllumbelliferyl-oleate lipase. Trioleylglycerol lipase activity was 14-60% of controls; tripalmitylglycerol lipase activity 14-25% of controls; and oleylcholestrol lipase activity 12-33% of controls.

The results from the studies on basic values of somatotropic hormone (STH) in 142 patients with diabetes mellitus are reported. No linear dependence was found between blood sugar and STH level in serum in the morning before meals. As compared with the subjects from a control group, STH in serum of diabetics without retinopathy, with retinopathy, with obesity and renal insufficiency resulting from nephropathy was increased with a statistical significance. STH values in serum of patients without microangiopathies were lower than those in patients with manifested retinopathy and higher than those in patients with obesity, the difference being not statistically significant. The serum level of somatotropic hormone in patients with manifested renal insufficiency was higher, with statistical significance, than that of patients without renal insufficiency.

Two growth hormone-binding proteins (GHBPs), one with high and the other with low affinity, have recently been described in the blood of humans and several other species. The high-affinity GHBP represents a circulating fragment of the GH receptor, encompassing its extracellular domain. The molecular nature of the low-affinity GHBP is not known in detail. GHBPs form complexes with circulating GH, prolong its biological half-life, restrict its distribution in the body, and modulate the binding of GH to receptors in tissues. Their net effect in vivo is to enhance GH action. The level of high-affinity GHBP in plasma probably reflects receptor concentrations in tissues. The level/activity of GHBP is linked to GH action, and several congenital or acquired conditions with altered GHBP levels are characterized by parallel changes in GH action (Laron-type dwarfism, pygmy dwarfism, malnutrition, obesity, insulin-dependent diabetes mellitus, liver cirrhosis, renal insufficiency). The GHBP/receptor level is nutritionally regulated, with levels low in undernutrition and high in overnutrition. Regulation of lean body mass anabolism/catabolism at the level of the GHBP/receptor provides a rational explanation for the derangements in the GH axis and their biological consequences (retarded or accelerated somatic growth) observed in nutrition disorders.

This review describes categories of renal function (normal, renal insufficiency, end-stage renal failure), types of treatment modalities (renal insufficiency management, dialysis, transplantation), and corresponding dietary parameters (protein, energy, fiber, sodium, fluid, potassium, phosphorus, calcium, vitamins, minerals). The focus is directed toward general and nonrenal specialty practitioners, who are encountering a growing number of geriatric patients and patients who have undergone renal transplantation or are in early renal failure. The findings indicate that early intervention may delay or prevent rapid progression of renal disease in some patients, that treatment modalities continue to need individualized dietary support to maintain nutritional status, and that transplant goals should include control of obesity and hyperlipidemia to reduce cardiovascular mortality.

Efficacy and acceptability of perindopril (Coversyl) in general practice were evaluated in 23,460 hypertensive patients (52.9% women) during an open six month trial. Patients had essential mild to moderate hypertension (94 mmHg < supine DBP < 115 mmHg) associated or not with obesity (34%), diabetes (12%), hypercholesterolemia (36%), smoking habits (24%). Mean hypertension duration was 6.5 years, 70 p. cent of patients were 50 to 69 years old and 12 p. cent 70 years old or more. Perindopril was started at 4 mg except in older and patients with renal insufficiency (2 mg). If supine DBP remained > 90 mmHg the dose was doubled up to 8 mg/day, then a thiazide diuretic was added. Monotherapy was held in 90 p. cent of cases all along the study, more than 8 over 10 times at 2 or 4 mg/day. Normalized patients (DBP < or = 90 mmHg) were 69.87 and 95 p. cent respectively at the first, third and sixth month. Mean supine SBP and DBP decrease were 27.3 and 18.0 mmHg. Antihypertensive activity was similar in patients taking psychotrope or non steroidal anti-inflammatory agents and in others, as well as in older (> or = 70 years), diabetics and obeses, however with a significantly more frequent bitherapy in these last three sub-groups. Cough, a well known side effect of ACEI led to withdrawal in only 2.6 p. cent of cases. Withdrawals for side-effect were more frequent in older patients (6.1%), in those taking psychotrope (5.3%) or non steroidal anti-inflammatory agents (6.0%) than in diabetics (4.1%) or the others (4.1%).(ABSTRACT TRUNCATED AT 250 WORDS)

Serum lipoprotein(a) [Lp(a)] concentrations in chronic renal failure patients were investigated in relation to the degree of renal insufficiency, treatment by maintenance hemodialysis, and correction of uremia by renal transplantation with or without cyclosporin immunosuppression. Fast serum levels of Lp(a) (mg/100 mL) were determined in 34 chronic renal failure patients not in need of maintenance dialysis (16 with serum creatinine 2.0-4.0 mg/100 mL; 18 with serum creatinine higher than 4.0 mg/100 mL), 40 patients treated by hemodialysis, 55 successful renal transplant recipients (28 under cyclosporin treatment and 27 receiving no cyclosporin), and 34 healthy controls. Age and sex distributions were similar among groups. Pregnant women; non-White individuals; subjects with obesity, diabetes, nephrotic syndrome, and hepatic and thyroid diseases; and those treated with oral contraceptives or lipid-lowering drugs were excluded from the study. Compared to controls, median Lp(a) was increased in nondialyzed renal failure patients (11 vs. 47.5 p < 0.001) and this was the only lipid abnormally observed in the group. There was no significant difference in Lp(a) levels between nondialized renal failure patients with serum creatinine 2.0-4.0 and > 4.0 mg/100 mL (47 vs. 49, NS). Moreover, Pearson correlation coefficient (r = 0.01, NS) showed that Lp(a) values were not related to serum creatinine in nondialyzed patients, In hemodialysis subjects Lp(a) concentrations (median = 29) were intermediate between those observed in nondialyzed patients and controls but the differences were not significant. Lp(a) levels in renal transplant patients treated with cyclosporin (median = 6) and not receiving cyclosporin (median = 13) were similar and did not differ from controls. Serum Lp(a) increases and attains maximum levels with mild/moderate reduction in renal function, and does not seem to change through late renal failure stages or in relation to the introduction of maintenance hemodialysis treatment. Correction of uremia by successful renal transplant caused normalization of Lp(a) levels regardless of the use of cyclosporin. Increased Lp(a) levels may be the earliest and more consistent lipid alteration seen in predialysis renal failure.

The purpose of this study was to determine the characteristics of gouty arthritis in an urban Guatemalan population. We reviewed the medical records of 148 (145 males and 3 females) patients with a diagnosis of acute gouty attack seen at an urban rheumatology clinic in Guatemala City between 1982 and 1993. Mean age at diagnosis was 49 years (range 21-87), mean age of onset was 42 years, mean duration of disease 7.4 years, family history of gout 42 (28%), peak prevalence 5th decade 39 (26%). Seventy-one (48%) had monarticular, 49 (33%) oligoarticular, and 22 (15%) polyarticular attacks, respectively. Podagra was seen in 34 (23%) patients; however, 108 (73%) developed it at any moment of their life. Tophaceous gout was seen in 33 (22%). Mean serum urate concentrations (enzymatic method) were higher than 7.0 mg % in 90 (60%) patients. At follow-up, 44 (30%) patients never returned to our clinic, and a large majority of them [66 (45%)] were seen only during acute attacks. Associated disorders included hypertension (43%), obesity (27%), nephrolithiasis (16%), ischaemic heart disease (7%), renal insufficiency (2%), stroke (0.6%), and diabetes mellitus (0.6%), and two died due to sepsis; high alcoholic intake was found in 58 (39%) patients. In conclusion, our findings indicate that gout is not an unusual disorder in the Guatemalan population. It presents with the same characteristics as those reported in Caucasians, with the possible exception of a lower frequency of diabetes mellitus as an associated disorder.

Treatment with low dose methotrexate in rheumatoid arthritis is associated with serious side effects in about 5 per cent of cases (respiratory, haematological or infectious). The goal of a null risk seems unrealistic because of the idiosyncrasy of some of the risks and our poor understanding of others (enzymatic polymorphisms might be operational, and infectious agents could act as co-factors). However, risk can be greatly reduced by a careful selection of patients. Some contraindications are strict: poor compliance and the possibility of mistake in the timing of the administration; pregnancy or desire for pregnancy; treatment with trimetoprim; haemodialysis; renal insufficiency (clearance < or = 50 ml/min) (and therefore old age), alcoholism. Others remain relative although well established; hypoalbuminaemia, diabetes mellitus, obesity, past infection with hepatitis virus. Others are dubious: starvation, macrocytosis, surgical stress, NSAIDs. An extensive large study of side effects is warranted.

Mutation of the Ob gene, which encodes for leptin, or mutation of the leptin receptor leads to obesity in mice. Humans, for the most part, have a positive correlation of leptin with body fat mass suggesting possible defects in leptin effector mechanisms that may contribute to obesity. As patients on hemodialysis have difficulty with appetite, we investigated whether leptin is cleared by the kidney and is elevated in hemodialysis patients. In patients with intact renal function there was a net renal uptake of 12% of circulating leptin, whereas in patients with renal insufficiency there was no renal uptake of leptin. In a separate cohort of 36 patients with end-stage renal disease (ESRD), peripheral leptin levels factored for body mass index was increased by fourfold as compared to a group of healthy controls (N = 338). The leptin receptor exists in a long and short form, with the long form primarily expressed in the hypothalamus but also in the lungs and kidneys of the mouse. Further studies are necessary to clarify the role of leptin in regulating appetite in patients with ESRD and the role of leptin in directly affecting kidney function via its receptors.

Hyperlipemia is frequent in liver transplanted patients and has been related with the existence of cholestasis, renal insufficiency, obesity, diabetes, and especially with immunosuppressant treatment. Although there are no studies that show a relationship between post-liver transplant hyperlipemia and the development of cardiovascular disease, there are data that indicate that liver transplanted patients should control their cholesterol levels to reduce the incidence of this disease. When post-transplant hyperlipemia is present, hygienic-dietary measures should be established and treatment should be carried out with the minimum dose of cyclosporine needed to maintain the graft stable. Corticoids should be discontinued as soon as possible. Treatment with some statins (Lovastatin and Pravastatin) has shown to be safe and efficacy in the liver transplanted patients with hypercholesterolemia.
