ABSTRACT
Our Study Aimed: To investigate the effect of laparoscopic sleeve gastrectomy (LSG) on obese T2DM patients, its effect in remission of diabetes and role of gastrointestinal Glucagon like peptide 1(GLP1) and Peptide tyrosine tyrosine (PYY) hormones.Metabolic surgery should be recommended as an option in type 2 diabetic patients (T2DM) with body mass index (BMI) ≥40 Kg/m2, in patients who have BMI ≥35 Kg/m2and in selected patients with BMI < 35 Kg/m2, if not achieving diabetes control with maximum tolerated anti-hyperglycemic treatment. Methods:30 T2DM patients with BMI ≥ 40 kg/m2underwent laparoscopic sleeve gastrectomy after full clinical evaluation, routine blood tests, glucagon like peptide 1, Peptide tyrosine tyrosine (fasting, 0.5-hour post-mixed meal test (MMT) serum levels) and upper GIT endoscopy. Follow-up visits were at 3, 6and 9 months postoperatively to evaluate body weight, BMI and glycated hemoglobin (HbA1C) and at 18thmonth for confirmation of diabetes remission. Gut hormones were measured at 15 days and 9 months postoperatively.Results: (53.3%) of patients had partial remission of T2DM according to HbA1C remission criteria. There was significant increase in fasting and post-MMT levels of peptide tyrosine tyrosine, glucagon like peptide 1 postoperatively. The only independent predictors for remission of T2DM were the baseline serum low density lipoprotein cholesterol (LDL-Ch), duration of diabetes, preoperative post MMT Peptide tyrosine tyrosine plasma level, serum thyroid stimulating hormone (TSH) and age. Conclusions: laparoscopic sleeve gastrectomycan induce partial remission of diabetes in younger patients who had shorter duration of diabetes, higher level of preoperative post-MMT peptide tyrosine tyrosine,lower levels of preoperative serum LDL-Ch and thyroid stimulating hormone
ABSTRACT
Refractory heart failure usually represents the end stage of congestive heart failure in which hypotension and oliguria, lead to progressive generalized edema. The purpose of this study was to assess the efficacy of extracorporeal ultrafilteration [ECUF] as a modality for treatment of patients with refractory congestive heart failure who failed to respond to conventional anti failure measures. The study was carried out at a period for about six months and it included 40 patients, 18 men [45%] and 22 women [55%], they were selected from patients admitted to the intensive care of Internal Medicine Department and cardiology Department of Tanta University Hospital. Selection criteria were NYHA class III and IV heart failure, resting left ventricular ejection fraction [LVEF] <35, normal or mild elevated serum creatinine [patients with chronic renal failure were excluded from the study], lack of satisfactory response to conventional therapeutic regimen. All patients were subjected To ECUF ranged from 3 sessions in 12 patients and 4 sessions in 28 patients [mean 3.7 session/ptn] and between [4-6 hour/session]. It was initated at a rate of 0.5L/h to be readjusted subsequently according to the hemodynamic parameters available. Average amount of ultrafilterate/session ranged from 2.5-3 liters [mean2.6 +/- 0.4]. Both number and repition frequency were decided empirically on the basis of evolution of symptoms and response to drugs. All patients were subjected to the following assessment before and after ECUF: Daily morning checking of body weight [kg], hematocrit value [HTC%], urin output [ml/24h], serum electrolytes [Na[+], K[+]], blood urea and serum creatinine, hemodynamic monitoring including [heart rate, blood pressure and CVP], chest x-ray P-A view for measurment of CTR, E.C.G and transthoracic echocardiography for evaluation of cardiac function. Our results showed that there was significant increase of diuresis from [0.3410.14 to 2.0 +/- 0.7L/day] [p<0.001], significant reduction of mean H.R [120+5.0 to 98 +/- 11.0 beat/min] [p<0.001], significant CVP reduction [28.5 +/- 2.o to 15.5 +/- 7.0 cm water] [p<0.001], decrease of intravenous volume as assessed by significant increase of HCT value from [33.8 +/- 2.3% to 37.6 +/- 2.0%] [p<0.001] after ECUF, significant decrease of S. urea from [105.7 +/- 55.2 to 91.3 +/- 63.o4 mmol/L] and S. creatinine from [1.9 +/- 0.6 to 1.5 +/- 0.9 mmol/L] after ECUF. ECHO repeated after ECUF revealed highly significant reduction in the mean LVEDD from [7.0 +/- 0.2 cm to 6.4 +/- 0.6 cm] [p<0.001], reduction of LVESD from [6.5 +/- 0.4 cm to 5.5 +/- 0.8 cm] [p<0.001], reduction in mean LA dimension from [5.3 +/- 0.3 cm to 4.8 +/- 0.6 cm] [p<0.001], reduction of RV dimension from [4.7 +/- 0.4 cm to 4.0 +/- 0.8 cm] [p<0.001], significant increase of LVEF from [23.8 +/- 4.1 to 31.2 +/- 8.2] [p<0.001]: ECUF offers a reasonable effective and relatively safe method in the treatment of refractory heart failure. The relative ease of the procedure and low incidence of complications denote that this technique is a useful one in selected cases of heart failure, refractory to the conventional therapy with oliguria and fluid overload
