Adverse Neonatal and Obstetric Outcomes in a 20-year Brazilian Retrospective Cohort of Pregnancies after Bariatric Surgery.

PURPOSE: Evaluation of obstetric and neonatal outcomes in a Brazilian retrospective cohort of pregnancies after Roux-en-Y gastric bypass (RYGB), regarding the 2009 Institute of Medicine (IOM) recommendations about gestational weight gain (GWG) and RYGB-conception interval. Additionally, search for intrapopulation risk factors for small gestational age (SGA) offspring and mental health assessments. MATERIAL AND METHODS: Retrospective analysis of 132 singleton pregnancies after RYGB. Obstetric and neonatal outcomes were analyzed with stratification in above, below, or meeting the target regarding GWG guidance, and 0-12, 12-47, and ≥48 months for RYGB-conception interval. SGA risk factors were identified through Poisson regression analysis. RESULTS: GWG below the recommendations was associated with prematurity (p 0.003). Late conceptions (≥48 months) were associated with iron deficiency (p 0.025). Parenteral iron prescription was a protective factor for SGA, with a relative risk of 0.41 (95% CI, 0.20-0.85; p 0.017), and GWG below target was a SGA risk factor, with a relative risk of 4.68 (95% CI, 1.48-14.8; p 0.008). In all, 15.2% of patients had psychopharmacological treatment during pregnancy, and 7.6% received a diagnosis of postpartum depression. Any alcohol and tobacco consumption were reported in 3.8 and 6.8% of patients, respectively. CONCLUSION: The recommendations regarding GWG apply to the RYGB population, and surgery-conception intervals should be individualized. The parenteral iron prescription was a protective factor for SGA, and GWG below the recommendations of the IOM was a risk factor for SGA. Psychological and psychiatric care should be offered to every possible pregnancy after RYGB.

Predictors of Long-Term Remission and Relapse of Type 2 Diabetes Mellitus Following Gastric Bypass in Severely Obese Patients.

BACKGROUND: Diabetes remission is not observed in all obese patients with type 2 diabetes submitted to bariatric surgery. Relapses occur in patients in whom remission is achieved. We investigated the factors associated with long-term (≥3 years) remission and relapse of type 2 diabetes after Roux-en-Y gastric bypass (RYGB) in these patients. METHODS: By a retrospective review, we analyzed data from 254 patients with type 2 diabetes who had undergone RYGB from May 2000 to November 2011 and had at least 3 years of follow-up. The criteria for remission and relapse of type 2 diabetes followed the current American Diabetes Association recommendations. RESULTS: Remission was achieved in almost 82% of participants (69.7% complete, and 12.2% partial remission). Of these, 12% relapsed within a mean follow-up of 5.1 ± 2.0 years after surgery. Predictors of complete remission were younger age, better preoperative glycemic control, and shorter diabetes duration. Preoperative insulin use was associated with a ninefold increase in the relapse hazard (HR = 9.1 (95% CI: 3.3-25.4)). Use of two or more oral anti-diabetic agents increased the relapse hazard sixfold (HR = 6.1 (95% CI: 1.8-20.6)). Eighteen point one percent of patients did not achieve any remission during follow-up. However, they exhibited significant improvements in glycemic control. CONCLUSIONS: These data indicate that RYGB should not be delayed when remission of type 2 diabetes is a therapeutic goal, and also suggest that the best possible metabolic control should be sought in obese patients who may eventually be candidates for RYGB.

Nutritional profile of patients before and after Roux-en-Y gastric bypass: 3-year follow-up.

BACKGROUND: Bariatric surgery is considered the most effective treatment for obesity class II and III. However, postoperative side effects may occur, such as nutritional deficiencies resulting from reduced gastric capacity and alterations in nutrient absorption along the gastrointestinal tract. METHODS: A total of 170 patients (136 women and 34 men) submitted to Roux-en-Y gastric bypass (RYGB) between 2000 and 2005 were retrospectively assessed. Anthropometric and laboratory data were evaluated and the use of vitamin and mineral supplements, before and 1, 6, 12, 24, and 36 months following surgery, was assessed, as well. RESULTS: Mean excess weight loss at 24 and 36 months was 81.5 ± 19.2 and 78.5 ± 20.8 %, respectively. Anemia was present in 6.5 % of subjects prior to the surgery and increased to 33.5 % at 36 months. The levels of total cholesterol, low-density lipoprotein cholesterol, triglycerides, and glycemia were reduced, while high-density lipoprotein cholesterol was increased. Albumin and vitamin B12 levels showed no significant differences at the end of the study compared to the preoperative evaluation. Folic acid levels increased significantly during the follow-up. Almost 6 % of the patients had used standard vitamin and mineral supplements in the preoperative period and 72.4, 85.3, 74.7, 77.1, and 72.4 % at 1, 6, 12, 24, and 36 months following RYGB, respectively. CONCLUSIONS: Bariatric surgery is an effective treatment for long-term weight loss. However, nutritional deficiency is one of its side effects and should be properly diagnosed and handled, aimed at improving the patient's quality of life and preventing severe complications.

Pregnancy after bariatric surgery: 39 pregnancies follow-up in a multidisciplinary team.

BACKGROUND: We investigate the outcomes of pregnancy in women who undergone restrictive-malabsorptive procedure at Centro da Obesidade Mórbida-Hospital São Lucas (COM HSL-PUCRS), Porto Alegre, Brazil. METHODS: All pregnancies started after the bariatric surgery and with estimated due date until June 2008 were eligible for the study. Only the first pregnancy of each patient was included in the data analysis. Data was collected from medical records. RESULTS: Forty seven pregnancies were identified in 41 women. Eight of them were ineligible. There were 30 complete pregnancies and nine miscarriages (23%). Cesarean delivery was performed in 69% of the complete pregnancies. Mature infants occurred in 93.1%. Twelve pregnancies (30.8%) occurred in the first year after surgery. Vitamin B12 was low in 53.4% patients; folic acid in 16.1%, iron in 6.7%, ferritin in 41.7%, calcium in 16.7%, and albumin in 10.3% of the patients. Nineteen women (79.2%) had no complication during the pregnancy and two (8.3%) presented with internal hernia. The average of newborns weight and length on delivery were 3,037 g and 48.07 cm, respectively. Children from pregnancies started in the first year of post operatory had similar outcomes of children from pregnancies started after 1 year of surgery. CONCLUSIONS: Pregnancy after bariatric surgery is safe and has fewer complications than pregnancy in morbidly obese women. However, the recommendation to delay the pregnancy for at least 12-18 months post-operatively should be kept.

Bone mineral density and nutritional profile in morbidly obese women.

BACKGROUND: Morbid obesity may be associated with malnutrition. Because it is important to assess the preoperative nutritional/metabolic status and bone mineral density of these patients, this study was designed aiming to evaluate bone metabolism/mineral density and nutritional profile in morbidly obese women. METHODS: Thirty-three morbidly obese women in preoperative care for obesity surgery were enrolled. Blood samples were drawn to determine nutritional and metabolic status, and dual-energy X-ray absorptiometry (DXA) was performed to evaluate bone mineral density; 24-h recall and food frequency questionnaire (FFQ) were also evaluated. RESULTS: Twenty-seven (81.8%) women were premenopausal and six (18.2%) were postmenopausal. The mean body mass index was 43.2 ± 4.8 kg/m(2), and 91% were Caucasian. Insulin-resistant subjects comprised 81.8% of the sample. The median (25-75 percentile) of the total intake of 24-h recall was 3,081 (2,718-3,737) and for FFQ 2,685 (2,284-4,400) calories. FFQ underestimated total energy value intake. The median of calcium was higher when evaluated by the FFQ as compared with the 24-h recall. Protein and lipid intakes were lower if evaluated by the FFQ as compared to the 24-h recall. Vitamin D levels were low in 18 (81.8%) patients. In one premenopausal woman, bone mineral density was low in the lumbar spine (L1-L4), and in one postmenopausal woman it was low in L1-L4, femoral neck and 1/3 proximal radius. CONCLUSIONS: In this study, the nutritional status of morbidly obese women was good, except for markers of bone metabolism, with no detectable differences between pre- and postmenopausal women.

Hepatic steatosis in patients undergoing bariatric surgery and its relationship to body mass index and co-morbidities.

BACKGROUND: Although non-alcoholic hepatitis usually is asymptomatic and benign, this condition may progress to cirrhosis and hepatic failure. Some findings are similar to alcoholic hepatitis, but there is no history of excessive alcohol consumption. Among the factors associated with non-alcoholic hepatitis, obesity, diabetes and dyslipidemia are the most important. METHODS: 77 consecutive patients undergoing bariatric surgery had their liver biopsy compared to the presence of co-morbidities and BMI. RESULTS: 67 patients (87.1%) had an abnormal liver biopsy, mostly due to steatosis (83.1%), but also steatohepatitis (2.6%) and cirrhosis (1.3%). The degree of liver damage was related to higher BMI scores. Co-morbidities were present in 46.9% of the patients with hepatic steatosis. CONCLUSIONS: The authors suggest that a liver biopsy should be performed in all patients at bariatric surgery, in order to evaluate possible liver damage and to assist postoperative care.
