“…In the definition of normality criteria, taking age into account has a biological basis and an empirical demonstration, but its implementation is more difficult from a practical point of view. It is also important to consider environmental, nutritional and reproductive behavior and the diversity of the ethnic composition of the population as determining factors for the variations found in the epidemiological profile as suggested by Harris & Pass 23 for the case of CH.…”

“…Even in Ribeirão Preto 18 , where the NBSP uses the same method and cut-off level as NSRC A, incidence was 1:2,595. Frequency has been increasing over recent years in many countries due to genetic, environmental and socio-cultural factors 4,5,23 . Harris & Pass 23 analyzed CH epidemiological behavior in the US over a 25-year-period and observed a continuous and pronounced increase in disease incidence that could be attributed to modifications in diagnostic criteria as well as to environmental factors (iodine intake), ethnic composition and reproductive behavior.…”

Phenylketonuria, congenital hypothyroidism and haemoglobinopathies: public health issues for a Brazilian newborn screening program

2012

In this study, the frequency of detected congenital hypothyroidism, phenylketonuria and haemoglobinopathies in the State of Rio de Janeiro's (Brazil) Newborn Screening Program (NBSP) was analyzed between the years of 2005 and 2007. There were two Newborn Screening Reference Centers (named NSRC A and B) with programmatic differences. In 2007, overall detection coverage reached 80.7%. The increase in the incidence of congenital hypothyroidism (1:1,030 in 2007) was attributed to the reduction of neonatal TSH value limits over time. The incidence discrepancy of phenylketonuria between NSRC A (1:28,427) and B (1:16,522) might be partially explained by the small number of cases. The incidence of sickle cell disease and its traits were uniformly high (1:1,288 and 1:21, respectively). This was coherent with the ethnic composition of the population. The differences in laboratory methods and critical values, in addition to other programmatic issues, may explain the variances in the results and limited analysis of the role of biological and environmental determinants in the occurrence of these diseases.

“…An increasing incidence of CHT has been suggested from an analyses of data including that from New York State [2] and Mexico [3], although no similar increase was shown in a similar study of data from Quebec [4]. Previous studies in the United Kingdom have suggested that CHT is more prevalent in Asian sectors of the population and that prevalence has increased [5].…”

“…El primer programa de tamizaje neonatal para HC fue creado en Canadá en 1974 y posteriormente en EUA en 1975, después del éxito del programa piloto realizado en Pittsburgh (Pennsylvania) (16) . Gracias al inicio del programa de tamizaje neonatal de HC en EUA, la identificación de neonatos con HC en este país se incrementó progresivamente de 1:4094 en 1987, a 1:2372 en el año 2002 (17) .…”

RESUMENEl hipotiroidismo congénito (HC) es la principal causa prevenible de retardo mental. La prevalencia de HC varía de acuerdo con la región geográfica y la población racial. En el hemisferio norte, la incidencia es 1:4000 recién nacidos vivos. En Latinoamérica, la incidencia varía debido a la heterogeneidad racial/étnica y al nivel de desarrollo. En el Perú, un estudio realizado en 1984 describió esta prevalencia como 1:1250. En el 2007, esta prevalencia fue reportada como 1:1638 por el Instituto Nacional Materno Perinatal. Un reciente estudio del Instituto Nacional de Salud del Niño durante 1995-2005, describió la edad promedio de diagnóstico de HC como 5,9 meses +/-5,28. Esta tardía edad de diagnóstico sugiere la poca eficiencia de los actuales programas de tamizaje. Todo niño peruano tiene derecho a recibir diagnóstico oportuno y tratamiento de HC y es el Estado Peruano, el responsable principal de asegurar que esta meta se cumpla.Palabras clave: Hipotiroidismo congénito; Tamizaje neonatal; Niño, Perú (fuente: DeCS BIREME). NATIONAL CONGENITAL HYPOTHYROIDISM SCREENING IN PERU: A BROKEN PROGRAM ABSTRACTCongenital hypothyroidism (CH) is the most important cause of preventable mental retardation. The prevalence of CH varies by geographic region, race and ethnicity. In the countries of the Northern hemisphere, the prevalence has been reported as 1:4,000 live newborns. The prevalence is remarkably different among the countries of Latin America not only because of their different races and ethnicities but also because of the heterogeneous social-economic development. The prevalence of CH in 1984 in Peru was reported as 1:1250. In 2007, the reported incidence by the Instituto Nacional Materno Perinatal was 1:1638. A recent retrospective study performed by the Instituto Nacional de Salud del Niño in Lima, Peru described the average age of diagnosis of CH as 5,9 months +/-5,28. This late age of CH diagnosis certainly suggests the poor efficiency of the current neonatal CH screening programs in Peru. Every Peruvian infant deserves a timely newborn screening and treatment for CH. The Peruvian government is responsible for ensuring this mandatory goal is achieved promptly.
