Physical Activity Protects Women with Type 1 Diabetes from Sexual Dysfunctions.

The aim of the study was to evaluate the relationship between physical activity and sexual function in women with type 1 diabetes mellitus (T1DM). The study group consisted of 171 women with T1DM. All the participants voluntarily filled out anonymous questionnaires. Women who were sexually inactive or had some psychological, psychiatric, or endocrine diseases were excluded from the analysis. The scores about sexual function were obtained using a Female Sexual Function Index (FSFI) questionnaire. Results equal to or below 26 points indicate clinically significant sexual dysfunction. Physical activity was measured by the International Physical Activity Questionnaire (IPAQ). Participants were divided into two groups depending on the Metabolic Equivalent of Task (MET-min/week) score with a cutoff point 3000 MET-min/week. Results above 3000 points indicate higher physical activity in woman. There were statistically significant differences in lubrication, orgasm, pain, satisfaction, and total score of FSFI. A positive correlation was revealed between results in total FSFI score and MET-min/week score (Rs = 0.18, p = 0.016). Univariate logistic regression does not show significant associations, but the multivariate logistic regression model shows an association between the MET-min/week and the total FSFI score. The higher the MET-min/week score, the higher the FSI score, and thus better sexual function.

Indirect insulin resistance markers are associated with nonalcoholic fatty liver disease in type 1 diabetes.

INTRODUCTION: Insulin resistance (IR) in type 1 diabetes mellitus (T1DM) is associated with increased insulin dose requirements, poor glycemic control, and elevated risk of chronic complications. IR increases lipid synthesis and hepatic lipid content. Disruption in hepatic lipid accumulation and export leads to liver steatosis resulting in nonalcoholic liver disease (NAFLD). OBJECTIVES: The aim of the study was to explore the relationship between indirect IR markers and NAFLD in T1DM. PATIENTS AND METHODS: We analyzed 151 patients with T1DM (59 men, 92 women), with a median (interquartile range [IQR]) age of 40 (33-47) years and a median (IQR) diabetes duration of 19 (13-21)years. The median (IQR) value of glycated hemoglobin (HbA1c) was 7.5% (6.8%-8.%; 58 [51-66] mmol/mol). The following indirect IR markers were evaluated: estimated glucose distribution rate (eGDR), visceral adiposity index (VAI), and the triglyceride to high­density lipoprotein cholesterol ratio (TG/HDL­C). Fatty infiltration of the liver was quantified using transient elastography. Presence of NAFLD was defined as a controlled attenuation parameter value of 238 dB/m or greater. RESULTS: NAFLD was observed in 65 patients (43%). The participants with NAFLD were less insulin­sensitive (eGDR, 8.93 [6.39-9.97] vs 9.94 [8.09-11.13] mg/kg/min; P = 0.001; VAI, 1.52 [1.2-2.64] vs 1.34 [0.92-1.74]; P = 0.014; TG/HDL­C ratio, 1.35 [0.95-2.11] vs 1.11 [0.77-1.6]; P = 0.02) and were characterized by higher HbA1c values (7.75% [7.2%-8.4%] vs 7.3% [6.5%-8.1%]; 61 [55-68] vs 56 [48-65] mmol/mol; P = 0.02) than the patients without the disease. In a multivariable regression analysis adjusted for sex, diabetes duration, and HbA1c level, indirect IR markers were independently associated with NAFLD (eGDR: odds ratio [OR], 0.86; 95% CI, 0.77-0.97; P = 0.01; VAI: OR, 1.61; 95% CI, 1.05-2.49; P = 0.03, TG/HDL­C ratio: OR, 1.88; 95% CI, 1.11-3.18; P = 0.02). CONCLUSIONS: In T1DM, NAFLD is more likely to be found in individuals with lower insulin sensitivity.

Safety and glycemic outcomes of do-it-yourself AndroidAPS hybrid closed-loop system in adults with type 1 diabetes.

BACKGROUND: The aim of the study was to assess the safety and glycemic outcomes with the use of a Do-It-Yourself (DIY) Hybrid Closed-Loop (HCL) system based on the AndroidAPS application in type 1 diabetes (T1D). METHODS: Single-center clinical trial, with 3-week run-in and 12-week study period. DIY HCL system consisted of the Dana Diabecare RS insulin pump, Dexcom G5 continuous glucose monitoring system and AndroidAPS application. Primary outcome was safety: incidences of severe hypoglycemia, diabetic ketoacidosis, time spent in glycemia <54 mg/dl. Secondary endpoints included percentage of time in range (TIR) 70-180 mg/dl, time below 70 mg/dl, HbA1c, insulin requirements, and body weight. RESULTS: In total 12 subjects (5 men, 7 women) were enrolled, mean age 31.3±6.7, 95%CI(27.7-34.9) years, mean diabetes duration 16.1±5.7, 95%CI(13.0-19.2) years. No episodes of severe hypoglycemia or ketoacidosis were observed. Percentage of time spent in glycemia below 54mg/dl was not increased. Average sensor glycemia was lower in the study period than baseline (141.1 ± 8.4, 95%CI(136.3-145.9) vs. 153.3 ± 17.9, 95%CI(143.2-163.4), mg/dl p<0.001). TIR 70-180 mg/dl was improved by 11.3%, 95%CI(2.8%-19.8%) (from 68.0 ± 12.7 to 79.3 ± 6.4%, p<0.001), without increasing hypoglycemia time. The HbA1c level decreased by -0.5%, 95%CI(-0.9%--0.1%) (from 6.8 ± 0.5 to 6.3 ± 0.4%, p<0.001). Additionally, in the last 4 weeks of the study period participants significantly improved and showed TIR 70-180 mg/dl 82.1 ± 5.6%, 95%CI(78.9-85.3), time <54 mg/dl 0.30 (0.20-0.55)%, median 95%CI(0.1-0.7) and <70 mg/dl 1.90 (1.10-3.05)%, median 95%CI(0.7-3.2). The insulin requirement and body weight did not change in the study. CONCLUSIONS: The study revealed safety of the Do-It-Yourself HCL system AndroidAPS in adults with T1D, limited to well-controlled, highly selected and closely monitored patients. The use of AndroidAPS significantly improved HbA1c, time in range and average sensor glycemia without increasing hypoglycemia. As both patients and their medical team are gaining experience using the system over time, they improve glycemic control. TRIAL REGISTRATION: German Clinical Trials Register: no.

Characteristics of Selected Somatic and Motor Abilities of Youth Soccer Players with Diabetes Type 1 Treated with Insulin Pump Therapy.

Long-term insulin treatment can slow the growth process and decrease physical fitness level in children. In diabetic children, these two developments should be constantly monitored. The aim of the present study was to examine differences in somatic and physical fitness characteristics between soccer-training boys with type 1 diabetes and healthy boys of the same age (reference values based on Polish population norms for somatic and motor parameters). The participants were 94 boys (8-17 years), diagnosed with diabetes, who participated in soccer training on a regular basis and received routine medical care. The study involved (a) anthropometric and body composition measurements, (b) general motor ability assessments, and (c) comparison of those characteristics with the healthy Polish population. The diabetic boys were found to have lower levels of almost all somatic traits and motor abilities as compared with the healthy boys (p ≤ 0.05). Handgrip strength was a variable with the smallest difference between the two groups. The observed differences indicate the necessity to design an appropriate control and assessment system based on simple medical and fitness field tests for diabetic children and adolescents. It will allow optimizing advanced training as well as minimize health risks before, during, or after exercise.

The Influence of Prepubertal Onset of Type 1 Diabetes and Age of Menarche on Polycystic Ovary Syndrome Diagnosis.

CONTEXT: Higher prevalence of polycystic ovary syndrome (PCOS) in women with type 1 diabetes (T1DM) is linked to exogenous insulin, especially when diabetes is diagnosed before puberty. OBJECTIVE: The study evaluates the impact of prepubertal onset of T1DM and insulin therapy on PCOS diagnosis and phenotypic characteristics in women with T1DM. DESIGN, SETTING, AND PATIENTS: We studied 83 women with T1DM (age 26 ± 5 years, BMI 24 ± 3 kg/m2) 36 with premenarchal (PM) onset of T1DM [17 with PCOS diagnosed (PCOS+PM) and 19 without PCOS (noPCOS+PM)] and 47 women with postmenarchal onset of T1DM [24 with PCOS (PCOS-noPM) and 23 without PCOS (noPCOS-noPM)]. OUTCOME MEASUREMENTS: Clinical examination, assessment of serum sex hormones, glycated hemoglobin (HbA1c) and ultrasonographic evaluation of the ovaries were performed in all women. RESULTS: Applying Rotterdam criteria, 49% of women with T1DM were diagnosed with PCOS. There were no differences in hormonal profile and ovarian parameters between PCOS+PM and PCOS-noPM. Women with T1DM+PM had higher insulin dose/24 h and U/kg bw/24 h than T1DM-noPM (P-values = 0.014 and 0.001, respectively). Both PCOS+PM and noPCOS+PM groups had higher insulin dose U/kg bw/24 h in comparison to PCOS-noPM (P-values = 0.004 and = 0.006, respectively). In multivariable logistic regression analysis, age of menarche [odds ratio (OR): 0.672; 95% confidence interval (CI): 0.465-0.971] and HbA1c (OR: 0.569; 95% CI: 0.383-0.846) were associated with the diagnosis of PCOS. CONCLUSIONS: There were no differences in the prevalence of PCOS between T1DM+PM and T1DM-noPM; however, earlier menarche might have an influence on PCOS diagnosis in women with T1DM.

Assessment of changes in blood lactate levels in children and adolescents with type 1 diabetes during a football tournament (GoalDiab Study).

INTRODUCTION: Monitoring physical activity is a very important issue, especially in type 1 diabetes. One of the parameters assessing the intensity of exercise is the concentration of lactate in the blood. Aim of the study We assessed the intensity of PE and changes in lactate levels in children and adolescents with type 1 diabetes (T1D) during a football tournament. MATERIAL AND METHODS: We enrolled 141 participants, the results of 70 of whom were analyzed, playing in two age categories: 10-13 and 14-17 years. Lactate levels were measured in the capillary blood before and after matches. Blood lactate of 4 mmol/l (Onset Blood Lactate Accumulation OBLA) was used as parameter indicating the prevalence of anaerobic metabolic changes. RESULTS: The median lactate level was 1.8 mmol/l before and 4.4 mmol/l after matches (p < 0.001). The increase in lactate levels was higher in the older age category (4.3 vs. 1.8, p = 0.001) and was independent on gender (3.2 vs. 2.1, p = 0.597), personal insulin pump vs insulin pen use (3.0 vs. 1.5, p = 0.145) or training in a sports club (1.4 vs. 3.0, p = 0.084). A positive correlation was noted between increased lactate levels and age (Rs = 0.253, p = 0.034). 61% of the participants exceeded lactate levels ≥ 4 mmol/l. In univariate logistic regression analysis age was a significantly associated with lactate level ≥ 4 mmol/l [OR = 1.45 (1.08-1.95)] independent of HbA1c, gender, treatment method and training in a sports club. CONCLUSIONS: PE intensity levels during football matches were found to be mixed aerobic-anaerobic. Increases in lactate levels were greater in the older subjects independently on the assessed factors.

Insulin Resistance in Adults with Type 1 Diabetes is Associated with Lower Vitamin D Serum Concentration.

AIM: Type 1 diabetes mellitus (T1DM) is a disease characterized by an absolute deficiency of endogenous insulin secretion. Insulin resistance (IR) may develop among patients with T1DM. Vitamin D deficiency was reported to be a risk factor in the development of IR. The aim of the study was to assess the relationship between serum concentrations of 25-hydroxyvitamin D (25(OH)D) and IR among patients with T1DM. METHODS: The test group consisted of 110 adult patients [males=65 (59%)] with T1DM. Participants were recruited in Poland between 1st October and 30th April in 2015/2016 and 2016/2017. VD serum level was assessed by ELISA array. IR was assessed by estimated Glucose Disposal Rate (eGDR). RESULTS: In the study group 21 (19%) patients were recognized as IR according to eGDR cut-offs (<7.5 mg/kg/min), 52 (47.3%) patients had VD deficiency (25(OH)D<20 ng/ml), 16 (14.5%) patients had 25(OH)D<10 ng/ml. Only 6 (5%) participants reported VD supplementation. Patients with IR, according to eGDR cut-off revealed significantly lower 25(OH)D serum level 15.7 (9.2-28.4) vs. 22.1 (13.0-38.4) ng/ml; p=0.04 as compared to patients without IR. R Spearman analysis found a positive relationship between VD and eGDR (Rs=0.27; p<0.01). Logistic regression analysis revealed significant relationship between the presence of IR and VD serum level/presence of 25(OH)D serum level below 10 ng/ml, both models adjusted to sex, age, BMI, LDL and triglycerides, accordingly (OR=0.95, CI: 0.90-0.99; p=0.04) and (OR=4.19, CI: 1.04-16.93; p=0.04). CONCLUSION: The serum concentration of Vitamin D is negatively associated with insulin resistance in patients with T1DM and may have clinical implications.

Nighttime Hypoglycemia in Children with Type 1 Diabetes after one Day of Football Tournament.

The aim of the study was to investigate factors related to the occurrence of nighttime hypoglycemia after a football tournament in children with type 1 diabetes mellitus. The multicenter study (GoalDiab study) included 189 children and adolescents with type 1 diabetes mellitus, from 11 diabetes care centers in Poland. Hypoglycemia was defined according to the International Hypoglycemia Study Group Statement. We analyzed the data of 95 participants with completed protocols with regards to nighttime hypoglycemia (82% male), aged 11.6 (9.8-14.2) years, diabetes duration 5.0 (2.0-8.0) years. There were 47 episodes of nighttime Level 1 hypoglycemia (≤3.9 mmol/L). Occurrence of clinically important Level 2 hypoglycemia (<3.0 mmol/L) during a game period was positively associated with nighttime hypoglycemia (≤3.9 mmol/L) incident (Odds Ratio=10.7; 95% Confidence Interval: 1.1-100.2; p=0.04). Using Continuous Glucose Monitoring was negatively associated with the occurrence of nighttime hypoglycemia (≤3.9 mmol/L) compared with using glucose meters or Flash Glucose Monitoring (Odds Ratio=0.31; 95% Confidence Interval: 0.12-0.83; p=0.02). The occurrence of clinically important hypoglycemia related to physical activity is associated with the occurrence of hypoglycemia during the night. Continuous Glucose Monitoring is negatively associated with nighttime hypoglycemia after a day of competition.

Insulin resistance is associated with impaired olfactory function in adult patients with type 1 diabetes: A cross-sectional study.

AIM: To investigate whether insulin resistance is a predictor for decreased olfactory function in adult type 1 diabetes patients (T1DM). MATERIALS AND METHODS: The following parameters were examined in the group of 113 T1DM participants: body mass index (BMI), waist-hip ratio (WHR), TG/HDL ratio, glycated hemoglobin (HbA1c ), visceral fat (VF) in body bioimpedance, specific calculators (eGDR, VAI). Bilateral olfactory test score (BOTS) was performed using 12-odour-tests from Sniffin' Sticks. Then participants were allocated to one of two groups: normosmia (10-12 odours identified) or hyposmia/anosmia (0-9 odours). The association between BOTS and insulin resistance indicators was analyzed using: Spearman's rank correlation, multivariate linear regression analysis, and receiver operating characteristic (ROC) curve. RESULTS: 49.6% participants were diagnosed with hyposmia/anosmia, median BOTS was 10. BOTS correlated significantly with: WHR, TG, VF index, TG/HDL ratio, VAI, and eGDR. In multivariate linear regression analysis higher WHR turned out to be statistically significant independent predictor of lower BOTS (ß = -0.36; P = .005) after adjustment for age, sex, TG and peripheral neuropathy (R2 = 0.19; P = .0005). The ROC analysis indicated a WHR cut-off of 0.92 [area under the ROC curve (AUC): 0.737; 95% confidence interval (CI): 0.647-0.828, P < .0001] as the best among evaluated factors significantly affecting hyposmia/anosmia occurrence (sensitivity of this cut-off 0.50 and specificity 0.86). CONCLUSIONS: We have provided evidence of an association between lowered insulin sensitivity expressed in bioelectrical impedance analysis, anthropometrical (WHR), laboratory (TG/HDL ratio) measurements, specific calculators (eGDR, VAI) and deteriorated olfactory function.

Novel Biochemical Markers of Neurovascular Complications in Type 1 Diabetes Patients.

Type 1 diabetes mellitus (T1DM) is associated with chronic complications, which are the result of neurovascular changes. There is still a lack of universal biochemical markers of microvascular damage. The present study aimed to investigate whether selected inflammatory proteins are related to the prevalence of microvascular complications in adult T1DM patients. The following markers were determined in a group of 100 T1DM participants: epidermal growth factor (EGF), metalloproteinase 2 (MMP-2), growth/differentiation factor 15 (GDF-15), and interleukin 29 (IL-29). Screening for microvascular complications, such as autonomic and peripheral neuropathy, diabetic kidney disease, and retinopathy, was conducted. The group was divided according to the occurrence of microvascular complications. At least one complication was required for the patient to be included in the microangiopathy group. The median EGF concentration in the microangiopathy group was higher than in the group without microangiopathy (p = 0.03). Increasing EGF concentration was a statistically significant predictor of the presence of microangiopathy in multivariate logistic regression analysis (p < 0.0001). Additionally, a higher GDF-15 level was associated with diabetic kidney disease, peripheral neuropathy, and proliferative retinopathy vs. nonproliferative retinopathy. GDF-15 concentration correlated negatively with estimated glomerular filtration rate (eGFR) (r = -0.28; p = 0.02). To conclude, higher EGF concentration is an independent predictor of the presence of microvascular complications in T1DM patients. Besides the relation between GDF-15 and diabetic kidney disease, it may be also associated with peripheral neuropathy and retinopathy.

An increased skin microvessel density is associated with neurovascular complications in type 1 diabetes mellitus.

The aim of this study was to assess the blood vessel density and maturity in the skin of adults with type 1 diabetes in relation to the presence of late neurovascular complications. We included 148 patients (87 men) with a median (interquartile range) age of 41 (31-49) and median diabetes duration of 21 (17-30) years. Microvessel (CD133, CD34, CD31 and von Willebrand factor) markers were evaluated by indirect immunohistochemistry assay in material from a skin biopsy. Diabetic retinopathy was diagnosed using direct ophthalmoscopy, and diabetic kidney disease was estimated in people with increased albuminuria and a 10-year duration of diabetes or evidence of diabetic retinopathy . Diabetic peripheral neuropathy diagnosis was based on Toronto definition, cardiac autonomic neuropathy on validated ProSciCard III program. Microvessel density, assessed by CD34 and CD133, was significantly higher in patients with cardiac autonomic neuropathy [160 (125-175) vs 121 (100-154)/1 mm2, p = 0.001 and 92 (83-104) vs 79 (63-92)/1 mm2, p = 0.007, respectively] and CD34 in patients with diabetic peripheral neuropathy [135 (106-168) vs 121 (95-145)/1 mm2, p = 0.018], as compared with subjects without complications. In multivariate logistic regression, density of CD34 and CD133 positive vessels was associated with presence of cardiac autonomic neuropathy [odds ratio 1.016 (95% confidence interval: 1.002-1.029), p = 0.019 and odds ratio 1.037 (95% confidence interval: 1.008-1.067), p = 0.011, respectively]. It was independent from age, sex, diabetes duration, smoking status, body mass index and HbA1c value. Density of CD34 positive vessels was also associated with diabetic peripheral neuropathy, independently from sex and diabetes duration [odds ratio 1.009 (95% confidence interval: 1.001-1.020), p = 0.037]. Skin microvessel density is increased in adults with clinical evidence of neurovascular complications of type 1 diabetes. This is associated with predominance of the vessels of low maturity.

Sexual Dysfunction Is a More Common Problem in Young Women with Type 1 Diabetes than in Healthy Women.

The aim of the study was to analyze the relationship between the presence of type 1 diabetes and sexual dysfunction among young women. The study group consisted of 230 women, including 70 healthy and 160 with diabetes mellitus type 1 (DM1). All the participants voluntarily filled anonymous questionnaire. The results regarding sexual function were obtained using a Female Sexual Function Index (FSFI) questionnaire. Statistical analysis was performed for sexually active people. In the study group, 180 women declared sexual activity: 62 healthy (88%) and 118 with DM1 (82.5%). Women with DM1 in comparison with healthy women were older, had higher BMI, weight, and had more pack-years of cigarette smoking. Women with DM1 had lower results in FSFI and more often achieved scores below the clinical cutoff point. In a multiple linear regression model, the presence of diabetes predicted lower FSFI results. DM1 is independently associated with the presence of impaired sexual function. Sexual dysfunctions are more common among young women with DM1 than in healthy controls. The relationship is significant despite of the age, duration of diabetes, body weight, and presence of angiopathy.

Assessment of Safety and Glycemic Control During Football Tournament in Children and Adolescents With Type 1 Diabetes-Results of GoalDiab Study.

PURPOSE: To assess glycemic control and safety of children and adolescents with type 1 diabetes participating in a 2-day football tournament. METHODS: In total, 189 children with type 1 diabetes from 11 diabetes care centers, in Poland, participated in a football tournament in 3 age categories: 7-9 (21.2%), 10-13 (42.9%), and 14-17 (36%) years. Participants were qualified and organized in 23 football teams, played 4 to 6 matches of 30 minutes, and were supervised by a medical team. Data on insulin dose and glycemia were downloaded from personal pumps, glucose meters, continuous glucose monitoring, and flash glucose monitoring systems. RESULTS: The median level of blood glucose before the matches was 6.78 (4.89-9.39) mmol/L, and after the matches, it was 7.39 (5.5-9.87) mmol/L (P = .001). There were no episodes of severe hypoglycemia or ketoacidosis. The number of episodes of low glucose value (blood glucose ≤3.9 mmol/L) was higher during the tournament versus 30 days before: 1.2 (0-1.5) versus 0.7 (0.3-1.1) event/person/day, P < .001. Lactate levels increased during the matches (2.2 [1.6-4.0] mmol/L to 4.4 [2.6-8.5] mmol/L after the matches, P < .001). CONCLUSIONS: Large football tournaments can be organized safely for children with type 1 diabetes. For the majority of children, moderate mixed aerobic-anaerobic effort did not adversely affect glycemic results and metabolic safety.

Dermal microvessel density and maturity is closely associated with atherogenic dyslipidemia and accumulation of advanced glycation end products in adult patients with type 1 diabetes.

In patients with diabetes, functional changes in microcirculation and subclinical vascular pathology precede clinical manifestation of microangiopathic complications. The objective of this study was to evaluate the association between established vascular risk factors and density, maturity, and reactivity of dermal blood vessels in adults with type 1 diabetes (DM1). We included 148 DM1 patients (87 men) with a median (IQR) age of 40.5 (30.5-49) years and a median diabetes duration of 21 (17-29.5) years. The control group consisted of 13 healthy volunteers (6 men) with a median (IQR) age of 36 (31-43). Accumulation of advanced glycation end products (AGEs) was assessed using the AGE-Reader device. In the immunohistochemical (IHC) analyses, anti-CD133, anti-CD34, anti-CD31, and anti-vWF autoantibodies were used. Microvessel density (MVD) in the skin was calculated using the "hot spots technique". Microvascular function was examined by single-point laser-Doppler flowmetry (LDF). Median MVD, calculated for both papillary and reticular dermis, for CD31 antigen expression was 38 (19-56) per 1 mm2. The median CD34+ blood vessel density was 121 (100-155) per 1 mm2, CD133+ was 79 (63-92) per 1 mm2, and vWF+ was 50 (40-69) per 1 mm2. The average CD34/CD31 index was 2.78, the vWF/CD31 ratio was 1.32 and the CD133/CD31 ratio was 1.75. The CD34/CD31 index was positively associated with serum triglyceride concentration (Beta: 0.26, p = 0.012) and negatively associated with serum HDL cholesterol concentration (Beta: -0.22, p = 0.027), both independently from age, sex, diabetes duration, BMI, HbA1c value, presence of hypertension, and eGFR. We found a negative correlation between MVD assessed by CD31 and skin AF (r = -0.21, p = 0.016). In LDF, the area under the blood flow/time curve (AUC) correlated positively with CD31+ MVD (r = 0.21, p = 0.011) and negatively with CD34+ MVD (r = -0.20, p = 0.017). The MVD did not differ between participants with diabetes and healthy controls, and it did not differ according to the presence of retinopathy among the participants with diabetes. Atherogenic dyslipidemia is associated with increased formation of new blood vessels, characterized by high expression of CD34 and low reactivity in LDF. Conversely, chronic hyperglycemia and excessive formation of AGEs may result in decreased vascularity.

Nonadherence to potassium replacement protocol leads to prolonged management of diabetic ketoacidosis.

Introduction Diabetic ketoacidosis is a life-threatening condition that requires prompt management. Objectives We aimed to assess the impact of adherence to potassium replacement protocol according to the guidelines of Diabetes Poland on the duration of diabetic ketoacidosis (DKA) treatment. Patients and methods This retrospective analysis included 242 adults (median age, 27 years; range, 21-38 years). Nonadherence to potassium replacement protocol was assessed, along with the relationship between nonadherence and duration of DKA management. Nonadherence to the protocol was defined as too low or too high doses of potassium compared with the recommended potassium replacement protocol. Results The median duration of DKA treatment was longer in the nonadherent group than in the adherent group: 37 hours (interquartile range [IQR], 27-48) and 30 hours (IQR, 17-43), respectively (P = 0.005). Treatment duration correlated positively with nonadherence to potassium replacement protocol (r = 0.18; P = 0.005) and severity of DKA (r = 0.52; P <0.0001). Stepwise multivariate linear regression analysis indicated nonadherence to the protocol (ß = 0.14; P = 0.02) and severity of DKA (ß = 0.43; P <0.0001) as predictors of treatment duration, after adjustment for body mass index and age (R2 = 0.28; P <0.0001). Conclusions Nonadherence to potassium replacement protocol leads to prolongation of DKA management. Medical staff should be educated about the benefits of potassium replacement and precision in potassium administration and dosing in patients with DKA.
