Tsoraeva, Anna; Muñoz del Campo, Jorge Luis
2005-12-01

Resumen en español Se evaluó una prueba rápida, en el diagnóstico de Escherichia coli, en diferentes tipos de muestras infecciosas, así como su comparación con los métodos bioquímicos de identificación tradicionales. Se ha reportado que la enzima glutamato descarboxilasa (GAD) es muy específica (97-99 %) para la identificación de Escherichia coli, sin embargo su empleo en la actualidad es muy limitado. Se analizaron 461 muestras clínicas de diferente origen en un hospital pediát (mas) rico. En general, con mayor frecuencia Escherichia coli fue aislada en muestras de urocultivo, coprocultivo, vaginales y uretrales. La sensibilidad diagnóstica del método fue de 100 %. Todas las cepas enterotoxigénicas y enterohemorrágicas de Escherichia coli aisladas en muestras de heces fecales también dieron los resultados positivos a la prueba rápida. La especificidad diagnóstica resultó ser de 82,8 %, debido a los resultados falsos positivos proporcionados por 34 cepas de Shigella del grupo D aisladas en coprocultivos. Las ventajas de la aplicación de esta prueba, comparadas con otras pruebas convencionales y comerciales, están dadas por su bajo costo, su rapidez y su alta sensibilidad, especificidad y exactitud diagnósticas, lo que permite ahorro de personal, de materiales y del tiempo empleado en la identificación. Resumen en inglés A rapid test was evaluated in the diagnosis of Escherichia coli in different types of infectious samples, and a comparison with the biomedical methods of traditional identification was made. It has been reported that glutamate decarboxylase (GAD) is very specific (97-99 %) for the identification of Escherichia coli; however, its use is very limited nowadays. 461 clinical samples of different origin were analyzed in a children’s hospital. In general, Escherichia coli (mas) , was more frequently isolated from urine, fecal, vaginal and urethral specimens. The diagnostic sensitivity of the method was 100 %. All the enterotoxigenic and enterohemorrhagical strains of Escherichia coli isolated from feces samples were also positive to the rapid test. The diagnostic specificity was 82.8 %, due to the false positive results yielded by 34 strains of Shigella of the group D isolated from feces. The advantages of the application of this test compared with other conventional and commercial tests are its low cost, its celerity and its high diagnostic sensitivity, specificity and accuracy, which allow to save personnel, materials and the time used in the identification.

Resumen en español Se sabe que la diabetes mellitus es un síndrome heterogéneo que tiene como elemento común una hiperglucemia crónica, como consecuencia de una deficiencia de insulina o una insuficiente efectividad de su acción. Nos propusimos en este trabajo describir los aspectos más relevantes de la diabetes autoinmune del adulto (LADA) y exponer el resultado de nuestra experiencia. Se considera que un sujeto la padece cuando es clasificado inicialmente como diabético tipo 2, el (mas) inicio es después de los 34 años, tiene generalmente peso corporal, normal o bajo y en un tiempo relativamente corto necesita tratamiento insulínico para lograr un buen control metabólico y presenta además una mayor asociación con la producción de anticuerpos antiislotes (ICA), antiglutámico descarboxilasa (AGAD65), microsomales tiroideos y antigástricos parietales, con una susceptibilidad genética por la presencia de haplotipos HLA-DR. Al momento del diagnóstico clínico puede presentar o no una insulinodeficiencia. Se ha demostrado que la insulinoterapia es el tratamiento ideal para los individuos con LADA, con el mismo se ha evidenciado una alta tasa de conversión negativa de los ICA con un incremento de los niveles de péptido C en el suero. Por el contrario, el tratamiento con sulfonilureas produce una persistencia de los ICA, los que probablemente sean responsables de una destrucción progresiva de las células b del páncreas. Por tanto, estas observaciones justifican la elección de la insulinoterapia desde el mismo momento del diagnóstico. Resumen en inglés It is known that diabetes mellitus is an heterogeneous syndrome that has as a common element a chronic hyperglycaemia resulting from an insulin deficiency or from an insufficient effectiveness of its action. It is our purpose to describe the most significant aspects of the autoimmune diabetes of the adult and to show the result of our experience. It is considered that subjects suffer from it when they are initially classified as type 2 diabetics, with an onset of the dise (mas) ase after the age of 34. They generally have normal or low body weight and in a relatively short time need insulin treatment to attain a good metabolic control. They also present a greater association with the production of islet cell antibodies (ICA), antiglutamic acid decarboxylase (AGAD65), thyroid microsomial antibodies and parietal antigastric antibodies, with a genetic susceptibility due to the presence of HLA-DR haplotypes. They may have or not insulin deficiency at the time of the clinical diagnosis. It has been proved that insulin therapy is the ideal treatment for individuals with LADA. A high rate of negative conversion of the ICA with an increase of the levels of C-peptide in serum has been evidenced. On the contrary, the sulphonylurea treatment produces a persistence of the ICA, which are probably responsible for the destruction of the b-cells of the pancreas. Therefore, these observations justify the election of insulin therapy at the very moment of the diagnosis.

Resumen en inglés Background: Some adult, obese and diabetic patients, initiate their disease with a severe diabetic ketoacidosis without a precipitating factor and do not require insulin thereafter. These patients are classified as having a "non classical" diabetes mellitus. Aim: To study the clinical, immunological, genetic and metabolic features of patients with non classical diabetes mellitus. Patients and methods: Ten patients (9 men, aged 45±12 years old) with non classical diabetes (mas) mellitus were studied. Anti islet and anti glutamic acid decarboxylase antibodies (ICA and anti GAD), HLA DQ a arginine 52 and non aspartic ß57 were measured. Insulin secretion was measured by C peptide after glucagon injection and with the minimal model of Bergman. The latter model was also used to determine insulin sensitivity. Results: Three patients were immunologically classified as type 1, since they had positive ICA or antiGAD antibodies and type 1 genetics (neutral or susceptible HLA DQ a and ß). They had insulin secretion after glucagon stimulus (C peptide ranging from 2.2 to 7.5 pmol/ml), but an almost absent response to a glucose load. They were also insulin resistant (a sensitivity index ranging from 0.05 to 1.67 x 10-4 min/µU x ml). These three cases could be categorized as latent type 1. The other seven patients were ICA negative and antiGAD negative. Five had a susceptible HLA genotype for type 1 diabetes and two were neutral. All had insulin secretion after glucagon stimulation and a variable response to glucose. Six were insulin resistant (sensitivity index ranging from 0.32 to 1.29 x 10-4 min/µU x ml). One patient was insulin sensitive (sensitivity index of 3.83 x 10-4 min/µU x ml). Therefore all these patients were classified as type two diabetics with an atypical debut. Conclusions: Not all diabetics presenting with a severe diabetic ketoacidosis are type I. Among these, there are subjects with a latent type 1 diabetes or with an atypical type 2 diabetes (Rev Med Chile 2001; 129: 853-60)

Resumen en español La PCT es la más común de las porfirias. Es una fotodermatosis que resulta de la deficiencia de la UPD, enzima perteneciente a la vía de síntesis del hemo. Presentamos la evolución de cinco casos de PCT; cuatro de PCT familiar y uno de PCT esporádica. En dos de los pacientes pertenecientes al grupo de PCT tipo II, encontramos como factor de riesgo, el consumo de alcohol, y en la paciente con PCT tipo I se detectó serología positiva para VHC. Todos los pacientes fu (mas) eron tratados con cloroquina y flebotomías repetidas. Rápidamente se detectó mejoría clínica y bioquímica. Se observó que la porfirinuria continuó en descenso aún luego de suspendida la terapéutica. Tres de los pacientes con PCT familiar persisten en remisión clínica y con ausenciade recaídas tras más de 10 años de seguimiento. Aconsejamos en pacientes que padecen PCT la búsqueda de factores asociados (VHC, HIV, genes de HH) y desencadenantes exógenos (consumo excesivo de alcohol, hierro en la dieta e ingesta de estrógenos) que de ser controlados o evitados, junto con el tratamiento oportuno, contribuyen a un satisfactorio control de la enfermedad. Resumen en inglés The porphyria cutanea tarda is the most frequent porphyria, it is a photodermatosis secondary to uroporphyrinogen decarboxylase deficiency; this enzyme belongs to the haem synthesis pathway. We present on this paper the evolution of five cases of PCT, four of them with familiar type and one of them sporadic type. In two patients belonging to PCT type II, we found alcohol addiction as a serious risk, while on the other patients PCT type I we found HCV positive serology. Al (mas) l patients were treated with chloroquine and phlebotomies. We could observe a good response not only clinical but biochemical. We could also see that the porphyrins urinary level continued descending once the drug was withdrew. Three of the patients with familiar PCT remains in clinical remission without any relapses in ten years of control. We advice all the patients that suffer PCT the detection of associated factors such as HCV, HIV, HH genes and the avoidance of the exogenous triggering factors such as excessive intake of alcohol, dietary iron and estrogen intake. Taking these advices into account, together with the correct treatment every patient can control this disease positively or satisfactorily.

Resumen en inglés Background: Islet cell-specific autoantibodies such as islet cell antibody (ICA), antiinsulin (IAA), anti-glutamic acid decarboxylase (GAD) and anti-tyrosine phosphatase (IA2) can be present in patients with type I diabetes. Breast feeding duration and the early exposure to milk substitutes are environmental factors associated to etiology of type 1 diabetes. Aim To study the frequency of the anti-GAD, anti-IA-2 e ICA antibodies in Chilean type 1 diabetic patients and dete (mas) rmine the possible modulator effect of the breast feeding. Patients and methods: One hundred thirty four type I diabetic patients, aged one to 15 years old, were studied at the moment of their diagnosis. Patients were classified according to the duration of exclusive breast feeding. IA-2 and GAD were determined by radio immuno assay and ICA by means of indirect immunofluorescence. Results: Subjects with three months or less and those with more than three months of breast feeding were positive for ICA in 78.8 and 90.6% of cases respectively, for GAD in 75 and 54.6% of cases respectively (p=0.024) and for IA-2 in 73 and 43.8% of cases respectively (p=0.001). All three antibodies were positive in 53.9 and 21.8% of children with less or more than three months of breast feeding (p=0.001). Conclusion: Both IA-2 and GAD antibodies are less frequently positive in type 1 diabetic patients who have been breast fed for more than three months. These findings suggest a possible attenuating role of exclusive breast feeding on pancreatic aggression events in patients with type 1 diabetes (Rev Méd Chile, 2001; 129: 611-9)

Resumen en español Los autoanticuerpos anti glutamato decarboxilasa y anti insulina/proinsulina (GADA e IAA/PAA) tienen valor predictivo del requerimiento insulínico en pacientes diabéticos con comienzo clínico en edad adulta. En este trabajo se desarrolló un nuevo trazador 35S-Proinsulina y se lo utilizó en un ensayo de unión de radioligando combinado con el trazador 35S-GAD para la determinación simultánea de GADA y PAA (RBA-combi). Se aplicó el ensayo a 85 pacientes infanto-juve (mas) niles con diabetes tipo 1, a 98 pacientes con comienzo clínico en edad adulta y a 53 controles normales. El 100% de los pacientes con diabetes tipo 1 con al menos un marcador positivo, y el 17,7% de los que eran negativos para ambos marcadores, fueron positivos por el RBA-combi (RBA-combi+). El 100% de los pacientes adultos PAA+ (GADA+ o GADA-), el 92,3% de los pacientes GADA+/PAA-, y el 1,3% de los pacientes GADA-/PAA-, fueron RBA-combi+. El 88,9% de los pacientes adultos RBA-combi+ evolucionaron a requerimiento insulínico. En conclusión, el nuevo trazador 35S-Proinsulina fue apto para su utilización en el método radiométrico combinado, permitiendo la detección simultánea de los marcadores GADA y PAA. El RBA-combi es una herramienta valiosa para detectar procesos autoinmunes asociados a un futuro requerimiento insulínico, en pacientes diabéticos adultos. Resumen en inglés The presence of the glutamate decarboxylase and insulin/proinsulin autoantibodies (GADA and IAA/PAA) can have predictive value about the insulin requirement in adult-onset diabetic patients. In this work, we developed a new tracer 35S-Proinsulin and it was employed in a combined radioligand binding assay with 35S-GAD for the simultaneous determination of GADA and PAA (RBA-combi). This novel assay was applied to sera from 85 young type 1 and 98 adult-onset diabetic patient (mas) s, and to 53 normal control. Among type 1 diabetes sera, 100% of those with at least one positive marker by single methods, and 17.7% of those with double negative markers, were positive by RBA-combi (RBA-combi+). Among sera from adult-onset diabetes, 100% of those PAA+ (GADA+ or GADA-), 92.3% of GADA+/PAA-, and 1.3% of GADA-/PAA-, were RBA-combi+. Moreover, 88.9% of adult patients RBA-combi+ evolved to insulin requirement, suggesting a good predictive value for this method. In conclusion, the new tracer 35S-Proinsulin was able to be used in the RBA-combi allowing the simultaneous detection of GADA and PAA markers. Such marker combination is a valuable tool for assessing autoimmune processes associated to future insulin requirement in adult-onset diabetes.

Resumen en inglés Background: Type 1 diabetes is an organ specifc autoimmune disease whose incidence is increasing worldwide. A functional imbalance in cytokine production resulting in dominance of T helper (Th1) over Th2-type response has been suggested to play a critical role in the pathogenesis of type 1 diabetes. Aim: To measure serum concentrations of interleukin (IL)-1ß, IL-2 and IL-4 in children with recently diagnosed type 1 diabetes and to evaluate the autoimmune response measuri (mas) ng glutamic acid decarboxylase (GAD65) and tyrosine phosphatase like (IA-2) autoantibodies. Patients and Methods: 120 diabetic children and 118 age and gender matched control children, were recruited for this study. Circulating levels of IL-1ß, IL-2 and IL-4 were measured by ELISA. GAD65 and IA-2 were measured by RIA. Results: Circulating levels of IL-1ß were elevated in type 1 diabetic children as compared to the control group (9.3±7.3 and 4.9±3.8 pg/ml respectively, p=0,01). Serum concentration of IL-2 was also higher in diabetic patients (19.8±13.1 and 11.3±9.1 pg/ml respectively, p=0,01). No differences in serum IL-4 were observed between diabetics and control. Diabetic children with one or two positive autoantibodies (IA-2 and/or GAD65) had significantly higher levels of IL-1ß and IL-2 and lower levels of IL-4 than diabetic children without positive autoantibodies. High concentrations of IL-1ß were associated with an early onset of the disease. Conclusions: High levels of IL-1ß and IL-2 were found in diabetic children with recent diagnosis of the disease. Diabetics with positive antibodies against GAD65 and IA-2 had higher levels of IL-1ß and IL-2 and lower levels of IL-4 than their counterparts without positive antibodies (Rev Méd Chile 2004; 132: 413-20)

Resumen en inglés Type 1 diabetes (DM1) is caused by an autoimmune process that destroys beta cells of pancreas. Not all carriers of susceptible HLA genes and positive for autoantibodies develop the disease. Environmental factors play a role in triggering the autoimmune process. Aim: To analyze an exceptional case of DM1 in a Mapuche family in the context of genetic, immunological and environmental factors. Subjects and methods: A study of a family with an affected female child was carried (mas) out in a Mapuche community in Southern Chile (VIII region). This is an unique and sporadic DM1 case with Mapuche heritage. Nutritional and viral infections data were collected by interview and clinical records. A genetic analysis by PCR was done to detect class I and II HLA genes by reverse dot blot. Results: The proband, her mother and sister had positive islet cell antibodies (ICA). Her father and brother were negative. All the family was positive for anti glutamic decarboxylase antibodies (GAD65). All subjects had HLA-DRB1 0407/0407 and HLA-DQB1 0302/0302 alleles. The index case and her father were homozygotes for the HLA-A1:A*68012/A*68012 allele. Mean breast feeding lapse was 18 months in all children. No evidences for viral infections such as rubella, mumps or measles were found in this family. Conclusions: There was an altered profile of autoantibodies in the family of the index case. All genotypes were comparable with the European population where the diabetogenic combination DR4/DQB1*0302 is the most prevalent. No environmental factors could be incriminated as triggers of the disease (Rev Méd Chile 2004; 132: 47-50)

Manifestación de porfiria cutánea tardía en pacientes infectados con el virus de la inmunodeficiencia humana/ Porphyria cutanea tarda manifestation in patients infected with human immunodeficiency virus

Resumen en español Las porfirias son consecuencia de una deficiencia parcial y específica de alguna de las enzimas del camino del hemo. En la Porfiria Cutánea Tardía (PCT) la deficiencia en la uroporfirinógeno decarboxilasa (URO-D) conduce a la acumulación de porfirinas altamente carboxiladas en hígado, plasma y orina. La enzima en sangre diferencia dos tipos de PCT: familiar y esporádica. Clínicamente presenta hiperpigmentación, hipertricosis, ampollas y fragilidad cutánea. En su (mas) patogénesis están implicados alcohol, estrógenos, drogas hepatotóxicas, compuestos polihalogenados, sobrecarga de hierro e infecciones con virus de hepatitis (VHC y VHB) y de la inmunodeficiencia humana (VIH). Se presenta una revisión de los pacientes PCT-VIH estudiados entre 1990 y 2004. Se diagnosticaron 91 individuos VIH como pacientes PCT (20 - 50 años), sólo 3 eran mujeres; 48 consumían alcohol y drogas de abuso, 16 consumían sólo alcohol, 10 eran adictos a drogas de abuso y 41 estaban coinfectados con VHC. En 25 pacientes había abuso de alcohol, drogas e infección con VHC. Sólo en 2 la URO-D estuvo disminuída. El tratamiento con bajas dosis de cloroquina y la terapia combinada (S-adenosil-L-metionina y cloroquina) fue bien tolerado con normalización de signos clínicos y bioquímicos. Se concluye que la población VIH positiva debería ser considerada como un grupo de riesgo de desarrollar PCT. Resumen en inglés Porphyrias are metabolic disorders caused by a decreased activity of one of the haem enzymes. Porphyria Cutanea Tarda (PCT) is due to subnormal activity of Uroporphyrinogen Decarboxylase (URO-D), and its value in erythrocytes allows differentiation between familiar and sporadic PCT, leading to increased levels of highly carboxylated porphyrins in liver, plasma and urine. Clinical symptoms include hyperpigmentation, hyperthricosis, blisters, skin photosensitivity and fragi (mas) lity. Factors such as alcohol, estrogens, polyhalogenated compounds, iron overload and infections with hepatitis viruses (HBV and HCV) and human immunodeficiency virus (HIV), have been implicated in its pathogenesis. All Argentine PCT-HIV cases studied from 1990 to 2004 were rewiewed. A group of 91 HIV positive subjects were diagnosed as PCT patients (20 to 50 years). Only 3 were women; 48 alcohol and drug abusers, 16 only heavy drinkers, 10 drug abusers and 41 were also coinfected with HCV. In 25 patients an overlapping of alcohol, drug abuse and HCV infection was found. In only 2 of the PCT-HIV studied URO-D was diminished. Treatment with low doses of chloroquine or the combined therapy (SAMe and chloroquine) is well tolerated, with normalization of clinical and biochemical signs. It can be concluded that HIV infected subjects should be considered a risk group, highly susceptible to developing Porphyria.

One-hundred and three persons with DM2 (negative ICA and AGAD), seen at the Diabetic Care Center, were studied and evaluated according to the following variables: age, sex, smoking, bod (mas) y mass index (BMI); age of onset of diabetes, type of DM treatment, presence of diabetic retinopathy (DR) and blood pressure as well as glucemia at fasting and postprandial. The study determined ICA, AGAD, glycosylated hemoglobin(HbA1), glucemia at fasting and postprandial two hours after breakfast and lunch as well as urinary albumin excretion (UAE) in urine collected for 24 hours. Patients with clinical diabetic nephropathy (UAE ³ 300 mg/L), non-diabetic nephropathy or other causes or conditions leading to increased UAE were excluded. The patients were divided into two groups: normoalbuminuric (UAE £ 20 mg/L) N = 163 and microalbuminuric (incipient DN, UAE >20 a
