Incidence of Type 1 diabetes and factors associated with presence and severity of ketoacidosis at onset in children.

BACKGROUND AND AIM: To assess the incidence of Type 1 Diabetes Mellitus (T1DM) during the period 2012-2017, the frequency and severity of ketoacidosis (DKA) at diabetes onset, and the factors associated with DKA in children and adolescents younger than 18 years old in the Abruzzo region, Italy. METHODS: All incident cases of T1DM (0-17 years old) diagnosed between January 2012 and December 2017 were included. Data about the patients were obtained from two independent sources; insulin prescriptions and medical records. Clinical data at diabetes onset, as well as demographic and non-demographic data, including center of first hospitalization, distance to regional reference center and number of pediatricians (per 1000 residents younger than 18 years) were collected and evaluated. RESULTS: During 2012-2017 period, 177 patients were diagnosed with T1DM. In 2012, T1DM incidence was 15.6 per 100,000/year; in 2013, 16.4 per 100,000/year; in 2014, 11.6 per 100,000/year; in 2015, 14.2 per 100,000/year; in 2016, 16.2 per 100,000/year and in 2017, 12.2 per 100,000/year. DKA was present in 29.3% of patients, 6.9% with severe DKA. The DKA presence was correlated to age (p<0.02), ethnicity (p<0.04), being transferred to a specialist center instead of being directly admitted to one (p<0.002) and the number of pediatricians in the population (p<0.01). The DKA severity was associated with the delay of transfer (p<0.04). CONCLUSIONS: Being admitted directly to a specialist center is very important and it could be expression of high alertness of pediatricians. Availability of well-trained pediatricians is necessary for the prevention of DKA. (www.actabiomedica.it).

Update of a colorimetric method for quantitative determination of galactose in blood samples: A simple and rapid method for the early detection of inherited metabolic diseases.

BACKGROUND: A colorimetric microassay for the quantitative determination of galactose in the blood was taken and updated. This method helps in diagnosis and follow-up of several inherited metabolic diseases connected to galactose metabolism deficiency such as galactosemia, glycogenosis, glycosylation, tyrosinemia and citrin deficiency. Galactose assay in the blood presents difficulties due to interference with glucose. In this study, we update a method to get around these difficulties. METHOD: This procedure was based on the incubation of whole blood with orcinol in a strongly acidic solution to form a galactose and glucose complexes able to absorb at two different wavelengths. RESULTS: The standard curve analysis for the individual solutions of these two sugars showed a wide range of linearity from 0 to 200 mg / l. Under optimal experimental conditions, the stirring time of the orcinol is 3 minutes, the heating time of the reaction is 20 minutes at 56 ° C, and the duration of the incubation in the dark is 40 minutes. The analysis is carried out on fresh blood. The maximum absorbance of galactose and glucose is respectively 569 nm and 421 nm. An adapted diagnosis algorithm was developed based on our results. CONCLUSION: this method could help in screening and identifying patients with hypergalactosemia that need further investigations. It could represent a promising method for neonatal screening in countries with limited resources.

A prospective multi-country observational trial to compare the incidences of diabetic ketoacidosis in the month of Ramadan, the preceding month, and the following month (DKAR international).

BACKGROUND: 1.7 billion Muslims worldwide obey divine commands of fasting for a month. This may increase the probability of the acute complications of diabetes during the fasting period. DESIGN AND METHODS: We primarily aimed to compare the incidences and duration of Diabetic ketoacidosis (DKA) admissions during Ramadan compared to the month before (Shaaban) and the month after (Shawal) as well as the average pre-Ramadan six months' admissions. Our secondary objective was to assess the different incidence of DKA between Ramadan and the other months regarding precipitating factors, fasting practices in people admitted with DKA and gender differences. This was a prospective study that included all Muslims who were admitted with DKA to major hospitals in the United Arab Emirates, Sudan, Tunisia and Morocco during the pre-Ramadan month, Ramadan and post-Ramadan month, in addition to the average monthly admissions during the last six months before Ramadan. Demographics, clinical, and laboratory indices were collected and analyzed to assess primary and secondary end points. RESULTS: One hundred seventy patients were admitted during the study duration, 56 were admitted during Ramadan and 63 in Shawal. Six months before Ramadan showed an average admission of 56 + 7 per month. All those admitted during Ramadan were people with type1 diabetes. 29.8 % of those admitted during Ramadan did not receive structured education program on diabetes management in Ramadan. Non-compliance to medications represented the commonest cause for admission in the whole study period. Hospital stay was comparable through different months, but the duration of acidosis was longest during Ramadan month. CONCLUSION: In concordance with DKAR1, DKAR international showed higher rates of DKA during Ramadan when compared to preceding Lunar month (Shaaban). In Shawal, however, the rates of DKA admission were higher than the average monthly DKA admissions. The duration of acidosis was longer in Ramadan group and positively correlated with duration of diabetes. Many patients did not receive structured education about diabetes and fasting Ramadan. Our study calls for formal pre-Ramadan education and enforces the need for advice against fasting in patients who already experienced DKA in the months preceding Ramadan.
