ABSTRACT

La lipodistrofia parcial (LDP) es una alteración poco frecuente en la cual se observa pérdida simétrica de tejidos adiposo subcutáneo que afecta la parte superior o inferior del cuerpo. Ocasionalmente la LD se produce solamente en las extremidades. En todos los casos se manifiesta con acantosis nigricans (AN), resistencia insulínica y alteraciones del metabolismo de lípidos e hidratos de carbono. Sedescribe el caso de una mujer de 49 años portadora de LDP adquirida con la pérdida de tejido adiposo en cara y parte superior del cuerpo. No se observa obesidad en la parte inferior del cuerpo. La paciente presentó adelgazamiento facial a los 8 años, AN a los 11 años y diabetes gestacional durante el cuarto embarazo a los 33 años. No tiene antecedentes familiares. Actualmente se detectan hiperglucemia severas y marcada resistencia insulínica. Presenta hiperlipoproteinemia tipo IV (OMS), C-HDL y Apo A1 disminuídos con C-LDL bajo pero con alta proporción de partículas LDL pequeñas y densas. Los ácidos grasos no esterificados (AGNE) estan elevados. Las actividades de lipoprotein lipasa (LPL) y lipasa hepática (LH) se hallan en el límite inferior y elevada respectivamente. La fracción C3 del complemento está disminuída. No se hallaron mutaciones en los condones 170, 809 y 972 del receptor IRS-1, ni en el condon 276 del gen beta2-adrenérgico.

ABSTRACT

The level of microabuminuria is considered an important marker for the early diagnosis and prediction of prognosis for long-term complications of Diabetes mellitus...The difference observed for the whole population must be ascribed to the female population, since for the male population there were no significant differences in such prevalence. A future and more ample study seems to be necessary in order to interpret if this difference can be realted to risk factors involving the gender profile for de development of microalbuminuria

ABSTRACT

Forty-nine normoalbuminuric diabetic patients were studied: 22 males and 27 females, in whom urinary heparan sulphate (HS), albuminuria, creatininemia, creatininuria, creatinine clearance, HbA1c and arterial pressure (AP) were determined. Two groups were discerned: group 1, Type 1 DM, diabetic cases (n = 16); and group 2, Type 2 DM diabetic cases (n = 33). Patients were compared with 24 healthy controls: 12 men and 12 women, who showed a mean value + SD of 0.36 + 0.18 mg/24 h HS with significant differences between males and females (0.43 + 0.15 versus 0.28 + 0.17, respectively; p = 0.02). The total population of diabetic cases rendered a mean of 0.68 + 0.44 and comparison with controls proved highly significant (p < 0.001). Globally, male patients had a mean of 0.82 + 0.48 and females 0.54 + 0.35, with p < 0.02. Group 1 and 2 values of HS were not significantly different. HS levels falled to correlate either with age, body mass index (BM), time since onset of diabetes, albuminuria, creatininemia, creatininuria, creatinine clearance, HbA1c or arterial hypertension. To conclude: both normal and diabetic males eliminate a greater quantity of HS than females. Normoalbuminuric diabetic patients of both types eliminate a greater quantity of HS regardiess of arterial pressure and time since onset of diabetes.

ABSTRACT

Se presenta una mujer de 33 años con una historia l1 meses de episodios recurrentes de hipoglucemia severa, asociados a anticuerpos anti-insulina y valores variables de peptido-C. Una extracción ácido-alcohólica de suero mostró un nível basal de insulina de 1.600 uU/ml. La insulina caracterizada por HPLC demostró ser insulina humana. Los anticuerpos fueron específicos para la insulina humana con una subpoblación que reaccionaba con insulina bovina y porcina (IgG, cadena liviana k). Al declinar los síntomas, el tratamiento con plasmaféresis negativizó el título con rapidez. Un seguimiento prolongado demostró la ausencia de recidivas.

ABSTRACT

Genetic hepatic lipase (HL) deficiency is associated with low density lipoprotein (LDL) rich in triglycerides (TG), whose affinity for B:E receptors is decreased. In rats, experimental hypoinsulinemia produces HL deficiency. However, the relation between human insulin-dependent Diabetes Mellitus (IDDM), HL activity and the characteristics of LDL have not been studied. The objective of our study is to evaluate the relation between HL activity and the chemical composition of LDL in treated IDDM patients. Subjects were 15 IDDM patients and 15 controls (C), matched for sex and body mass index (BMI). The IDDM patients were classified by the WHO criteria, were free of nephropathy and hypothyroidism, and received no medication except insulin. Controls were clinically healthy and normolipidemic with no family history of diabetes. The IDDM group was divided into two subgroups: subgroup IDDM-A (n = 9) with HL values > 4.3 and IDDM-B (n = 6) with HL < than 4.2 mu-moles glycerol/ml h. The HL in IDDM was lower than in C (p < 0.001). Table 1 shows clinical data. Blood samples were drawn after 12 h fasting. Percentage of HbAlc and plasma concentrations of glucose, total cholesterol, LDL-cholesterol, HDL-cholesterol and TG were assayed. LDL was separated by sequential ultracentrifugation at densities of 1.019-1.063 g/ml and its chemical composition was analyzed. The most relevant results were: plasma TG concentration was higher in IDDM than in C (p < 0.05) (Table 2), although average values DMID not exceed the reference values of 200 mg/dl. The TG-LDL were higher in IDDM than in C: 24.8 +/- 2.7 vs 17.5 +/- 1.1 mg/dl plasma, media +/- SE, (p < 0.02). This difference reflected the values of IDDM-B, whose plasma concentrations of TG-LDL were higher than in C: 32.3 +/- 3.6 vs 17.5 +/- 1.1 mg/dl (p < 0.001), and also higher than in IDDMA (p < 0.02). (Table 3). The chemical composition of LDL in IDDM-B contained a higher percentage of TG than C: 8.5 +/- 0.7 vs 6.8 +/- 0.3 percent (p < 0.05), a lower percentage of cholesterol than IDDM-A: 39.0 +/- 1.7 vs 45.2 +/- 2.2 percent (p < 0.05) and also a larger percentage of proteins than IDDM-A: 28.9 +/- 1.9 vs 20.8 +/- 1.0 percent (p < 0.01). The correlations between TG/cholesterol and HL activity in IDDM were r = -0.53 (p < 0.05) and in IDDM-B, r = -0.81 (p = 0.05). The noteworthy result of this study is the modification of the LDL particle in IDDM, rich in TG in patients with low HL activity. Anomalies in the chemical composition of LDL like those described decrease the uptake of this particle by its physiological B:E receptors. It has recently been demonstrated that LDL is an indissoluble association of lipids and apoproteins, and that both act simultaneously to hold the apoB in a spatial position that expresses normal epitopes. It has been described that particles of LDL rich in TG and poor in cholesterol, shows low affinity for LDL receptors in human fibroblasts. Also in IDDM the interaction of LDL rich in TG with B:E receptors is decreased. This might be one more mechanism contributing to the accelerated atherosclerosis of these patients. Our results suggest that there may be a threshold of HL activity for the complete hydrolysis of the TG of LDL, for the normalization of the TG/cholesterol relation and for the conformation of typical LDL particles.

ABSTRACT

El objetivo de este trabajo fue evaluar la eficacia y la tolerancia del tolrestat en el tratamiento de la neuropatía periférica sintomática o asintomática de corta evolución (menor de dos años), con disminución de la velocidad de conducción nerviosa motora en pacientes con diabetes mellitus insulinodependiente (DMID) y diabetes mellitus no insulinodependiente (DMNID). En treinta y ocho pacientes diabéticos (veinte DMID y dieciocho DMNID), tratados durante doce meses con 200 mg/día de tolrestat, se efectuaron cada cuatro meses exámenesneurológicos, pruebas electrofisiologicas y de la función autonómica a nivel cardiovascular. Simultáneamente se realizaron controles clínicos y de laboratorio. Se observó una disminución significativa de los síntomas motores y sensoriales referidos espontáneamente a partir del segundo y tercer mes de tratamiento, la velocidad promedio de conducción nerviosa motora de los nervios mediano y peroneo mostró un incremento en la última etapa del tratamiento. Resultados semejantes se obtuvieron con la latencia distal. La velocidad de conducción nerviosa del nervio safeno externo se mantuvo constante durante el año de tratamiento. No se registraron modificaciones significativas a nivel del sistema nervioso autonómico cardiovascular. La evolución de los valores enzimáticos mostró un leve aumento dela lacticodeshidrogenasa y de la transaminasa glutamicopiorévica en el grupo DMID, así como de la fosfatasa alcalina en el grupo DMNID.Dichos valores descendieron espontáneamente luego del quinto mes de tratamiento,habiéndose mantenido siempre dentro de los límites normales para los métodos utilizados
