Risk factors for suboptimal glycemic control in pediatrics with type 1 diabetes mellitus: a cross-sectional study.

The objective of this research is to analyze the influence of various factors on glycemic control in pediatrics with type 1 diabetes mellitus (T1DM). The study, a cross-sectional analysis, involved 221 T1DM patients below 18 years old who visited our clinic between 2011 and 2020, predating the COVID-19 outbreak. Out of the initial pool, 204 participants were chosen based on specific criteria. By computing odds ratios and 95% confidence intervals, we determined the correlation between these factors and achieving optimal glycemic control (HbA1c < 7.5%). Of the 204 individuals, 55.9% (113 patients) were female. The average age at diagnosis was 6.93 ± 3.9 years. Mean HbA1c (A1C) level of optimal and suboptimal groups were 6.97, 95% CI 6.84 to 7.1 and 8.86, 95% CI 8.68 to 9.03, respectively (p-value < 0.001). Fifty patients had optimal glycemic control and 154 people experienced suboptimal glycemic control during the follow-up that the prevalence of each of them was 24.51, 95% CI 18.7 to 31 and 75.49, 95% CI 68.99 to 81.22, respectively. In the assessment of risk factors associated with suboptimal glycemic control, patients aged 10-14 years had the highest likelihood of experiencing suboptimal glycemic control (crude odds ratio [COR] 3.12, 95% CI 1.04 to 9.3), followed by duration of diabetes (COR 2.85, 95% CI 1.2 to 6.8), which both were significant. By utilizing multivariable logistic regression analysis, a noteworthy finding emerged. It was revealed that patients aged 10-14 years exhibited a significant association with suboptimal glycemic control, [adjusted odds ratio (AOR) 4.85, 95% CI 1.32 to 17.7]. Additionally, a statistically significant correlation was identified between individuals with a body mass index (BMI) falling within the ≥ 95th percentile category and suboptimal glycemic control, Cramer's V = 0.21, p-value = 0.01. Our research has revealed a significant correlation between patients aged 10-14 years and obese individuals (BMI ≥ 95th) with suboptimal glycemic control. It is crucial to consider these factors as they can offer valuable insights during diagnosis, highlighting the increased risk of long-term suboptimal glycemic control.

Two risk factors for hypozincemia in diabetic ß-thalassemia patients: Hepatitis C and deferasirox.

BACKGROUND AND AIM: Hypozincemia is a prevalent adverse consequence in diabetes mellitus (DM) and ß-Thalassemia patients. We aimed to evaluate the level of serum zinc in ß-thalassemia patients with DM and a risk assessment for hypozincemia. METHODS: The study population included transfusion-dependent thalassemia (TDT) and non-transfusion-dependent thalassemia (NTDT) with overt DM (fasting plasma glucose (FPG) ≥126 mg/dL, and/or 2-h plasma glucose≥200 mg/dL). Serum zinc concentration was measured by the colorimetric method, and the values below 70 µg/dL were defined as hypozincemia. Myocardial and liver T2*-weighted magnetic resonance imaging (MRI T2*, millisecond [ms]) were valued by a free contrast MRI. The demographic, clinical, paraclinical, and laboratory data were also recorded. The data belonged to the period from December 2018 until December 2020. RESULTS: Of 64 diabetic ß-thalassemia patients, 41 cases had zinc data in their medical files (aged 38 ± 9 years, 48.8% female). 78.05% of patients (n = 32) were TDT, and 21.95% were NTDT (n = 9). The mean ± standard deviation of zinc level was 110.2 ± 127.6 µg/dL. The prevalence of hypozincemia was 9.76%, 95% confidence interval [CI] 0.27 to 19.24 (four cases). After controlling age, the odds of hypozincemia for using deferasirox (DFX) was 8.77, 95% CI 0.60 to 127.1. In ß-thalassemia patients, the age-adjusted risk of hypozincemia was calculated at 15.85, 95% CI 0.47 to 529.3 for hepatitis C. The adjusted risk of hypozincemia based on age for antacid use was 6.34, 95% CI 0.39 to 102.7. CONCLUSION: In light of this study, as well as hepatitis C, using DFX and antacids is associated with a high risk of hypozincemia amid diabetic ß-thalassemia cases. However, upward bias should be taken into consideration.

Report of an Iranian child with chronic abdominal pain and constipation diagnosed as glycogen storage disease type IX: a case report.

BACKGROUND: Glycogen storage disease type IX is a rare disorder that can cause a wide variety of symptoms depending on the specific deficiency of the phosphorylase kinase enzyme and the organs it affects. CASE PRESENTATION: A 4-and-a-half-year-old Caucasian girl was referred to our clinic with a liver biopsy report indicating a diagnosis of glycogen storage disease. Prior to being referred to our clinic, the patient had been under the care of pediatric gastroenterologists. The patient's initial symptoms included chronic abdominal pain, constipation, and elevated liver transaminase. With the help of the pediatric gastroenterologists, cholestasis, Wilson disease, and autoimmune hepatitis were ruled out. Given that glycogen storage diseases type I and type III are the most common, we initially managed the patient with frequent feedings and a diet that included complex carbohydrates such as a corn starch supplement and a lactose restriction. Following an unfavorable growth velocity and hepatomegaly during the follow-up period, genetic analysis was conducted, which revealed a novel mutation of the phosphorylase kinase regulatory subunit beta gene- a c.C412T (P.Q138x) mutation. As the diagnosis of glycogen storage disease type IX was confirmed, the treatment regimen was altered to a high protein diet (more than 2 g/kg/day) and a low fat diet. CONCLUSION: Given the mild and varied clinical manifestations of glycogen storage disease type IX, it is possible for the diagnosis to be overlooked. It is important to consider glycogen storage disease type IX in children who present with unexplained hepatomegaly and elevated transaminase levels. Furthermore, due to the distinct management of glycogen storage disease type IX compared with glycogen storage disease type I and glycogen storage disease type III, genetic analysis is essential for an accurate diagnosis.

Ebselen: A promising therapy protecting cardiomyocytes from excess iron in iron-overloaded thalassemia patients.

Iron-overload-associated cardiomyopathy has been one of the primary causes of mortality in thalassemia patients with iron burden. There is growing evidence citing the beneficial effects of ebselen as an antioxidant selectively blocking the divalent metal transporter 1 (DMT-1) to deter iron ingress into cardiomyocytes, raising internets in viewing this component in this population in order to treat and even prevent cardiomyopathy occurring from iron surplus. In this article, we reviewed the potential advantageous effects of ebselen in thalassemia patients who suffer from iron excess, susceptible to cardiomyopathy induced by iron overload. A systematic search in several databases, including PubMed, Scopus, and Web of Science, was conducted to explore the role of ebselen in controlling iron-overload-related cardiomyopathy in thalassemia patients by the keywords of Ebselen AND iron. The inclusion criteria were English-written preclinical and clinical studies investigating the efficacy and side effects of ebselen in an iron-overload context. After searching the databases, 44 articles were found. Next, of 19 published articles, 3 were included in this article. After reviewing the references of the included studies, no articles were added. In conclusion ebselen can be a promising adjuvant therapy in patients with thalassemia alongside the standard treatment with iron chelators, particularly in severe cases with cardiomyopathy, due to falling iron inflow by inhibiting DMT-1 and increasing ferroportin-1 expression and antioxidant properties. However, clinical studies need to be carried out to reach a definite conclusion.

Relationship between medical history and multiple sclerosis: A-case-control study.

This project sought to explore the potential association between medical history and the development of multiple sclerosis (MS) by conducting a retrospective study. This population-based case-control study included 200 MS cases and 2 control groups of 200 patients and healthy individuals each. Data was collected through face-to-face interviews, medical file reviews, and an electronic checklist. Multivariable analysis was used to calculate odds ratios and 95% confidence intervals to estimate the risk of each medical history on MS occurrences. Of 600 participants, 381 (63.5%) individuals were female. The mean age of the participants was 36.5 ±â€…11.9 years. The adjusted risks of MS were 4.40; 95% CI: 1.73 to 11.1 for measles and 4.75; 95% CI: 2.05 to 11 for amoxicillin consumption. The adjusted MS odds for autoimmune disease including 4.63; 95% CI: 0.35 to 60.6 for psoriasis and 7.15; 95% CI: 1.87 to 27.2 for myasthenia gravis. On the other hand, the calculated adjusted odds of MS occurrence were 0.14; 95% CI: 0.03 to 0.69 for seizure and 0.17; 95% CI: 0.02 to 1.49 for epilepsy. This study suggested that individuals with autoimmune diseases should be monitored more closely, as they may be at an increased risk of developing other autoimmune conditions, particularly MS.

An overview of CYP27B1 enzyme mutation and management: A case report and review of the literature.

Vitamin D-dependent rickets type 1 (VDDRIA) is an autosomal recessive disorder caused by mutations in the Cytochrome P450 Family 27 Subfamily B Member 1 (CYP27B1) gene, which encodes for the enzyme 1 alpha-hydroxylase. We report a known case of VDDRIA with hypotonia, growth and developmental disorders and discuss about the mutation and its management.

The effects of colchicine on hospitalized COVID-19 patients: A randomized, double-blind, placebo-controlled clinical trial.

This study was designed to evaluate the effects of colchicine in the improvement of clinical outcomes of hospitalized COVID-19 patients. This prospective, randomized, double-blind, placebo-controlled clinical trial was conducted on adult patients (>18 years) with severe COVID-19. The included patients were randomly (1:1) assigned to the colchicine (2 mg loading dose followed by 0.5 mg twice daily for 7 days) or placebo group. Both groups received remdesivir and interferon beta-1b. The primary outcome of the study was to receive clinical response as ordinal scale of 1 or 2. Secondary outcomes were hospital complications and 28-day mortality. Between February and May 2021, 110 patients were included and 106 of them were analyzed. Baseline clinical characteristics and demographics were not significantly different. According to the ordinal scale, 30 patients in the control group (58.8%) responded to treatment within 7 days, while 35 patients (63.6%) in the colchicine group showed the same response (p = 0.61, odds ratio (OR) = 1.23, 95% CI [0.560-2.68]). On the 14th day, 87.3% of the colchicine group (n = 48) and 82.4% of the control group (n = 42) responded (p = 0.48, OR = 1.47, 95% CI [0.50.3-4.29]. In addition, 28-day mortality, intensive care unit admission, and hospital duration were not different between the groups (p = 0.99, 0.59, 0.06). Diarrhea and nausea were the major side effects dominant in the colchicine group. Colchicine showed no beneficial effects on clinical improvement and hospital complications in patients with COVID-19. Moreover, in case of prescription, the safety concerns of colchicine, specially gastrointestinal side effects, should be taken into account.

Ferritin thresholds for cardiac and liver hemosiderosis in ß-thalassemia patients: a diagnostic accuracy study.

Ferritin is frequently used to screen some dire consequences of iron overload in ß-thalassemia patients. The study aimed to define the best cutoff point of ferritin to screen for cardiac and liver hemosiderosis in these cases. This was a registry-based study on ß-thalassemia patients living throughout Mazandaran province, Iran (n = 1959). In this diagnostic research, the index test was ferritin levels measured by a chemiluminescent immunoassay. As a reference test, T2*-weighted magnetic resonance imaging (T2*-weighted MRI) was applied to determine cardiac and liver hemosiderosis. A cutoff point of 2027 ng/mL for ferritin showed a sensitivity of 50%, specificity 77.4%, PPV 42.1%, and NPV 82.5% for cardiac hemosiderosis (area under curve [AUC] 0.66, 95% CI 0.60-0.71, adjusted odds ratio [OR] 2.05, 95% CI 1.05-4.01). At an optimum cutoff point of 1090 ng/mL, sensitivity 66.7%, specificity 68%, PPV 82.9%, and NPV 46.8% for liver hemosiderosis were estimated (AUC 0.68, 95% CI 0.63-0.73, adjusted OR 3.93, 95% CI 2.02-7.64. The likelihood of cardiac hemosiderosis serum ferritin levels below 2027 ng/mL is 17.5%. Moreover, 82.9% of ß-thalassemia patients with serum ferritin levels above 1090 ng/mL may suffer from liver hemosiderosis, regardless of the grades.

Atazanavir versus lopinavir on Covid-19 infection: A retrospective protease inhibitors comparative study 2020.

Background: Evaluation of protease inhibitors (PIs) is important in terms of prescribing an effective regimen for reducing mortality and hospitalization in Covid-19. Therefore, follow-up of patients better determines the characteristics of existing regimens. Methods: We retrospectively evaluated the demographic, co-morbidities, gastrointestinal (GI) and liver complications of patients at two teaching hospitals from the first of March to the end of July 2020. All patients received one of two recommended regimens including hydroxychloroquine (HCQ) (400 mg BD on the first day and then 200 mg BD) plus atazanavir/ritonavir (ATV) (300/100 mg daily) or HCQ with the same dose plus lopinavir/ritonavir (Kaletra) (400/100 mg BD) for 5-7 days. Results: We chose 170 cases that received 2 different regimens. In group one, 85(57.6% males) patients received Kaletra and HCQ and group two, 85 (55.3% males) patients received ATV and HCQ. The study of hospitalization in both groups showed no difference in more or less than 5 days hospitalization. (P=0.757) Comparison of mortality rates has not shown a significant difference including 19 (22.4%) deaths in group 1 and 15(17.6%) deaths in group 2 (P=0.443). Nausea followed by diarrhea was the most common side effects in group 1. But no side effects were reported in group 2 (P=0.000). Abnormal liver function tests (LFTs) were seen in both groups. Conclusion: Comparison of hospitalization and mortality were not statistically significant. It seems that a respect to similar effect on mortality and hospitalization. ATV regimen is superior to Kaletra especially for better GI tolerance and less daily pills.
