Cholelithiasis in patients treated with a very-low-calorie diet.

One hundred seventy-nine obese patients (mean body mass index = 36.3) were retrospectively evaluated for the development of cholelithiasis associated with the use of a 2530-kJ/d (605-kcal) very-low-calorie diet (VLCD). Nine percent of patients had preexisting gallstones and 11% of patients developed gallstones either during or within 6 mo of completing the diet. Six percent had subsequent cholecystectomy. Ursodeoxycholic acid administered to one patient resulted in spontaneous stone dissolution whereas spontaneous dissolution occurred in three patients. Surveys of patients at three other programs using the same diet yielded similar incidence of gallstones. We conclude that rapid weight loss associated with the use of VLCD is associated with a significant incidence of gallstone formation. VLCD should be physician supervised because resolution of cholelithiasis spontaneously, with stone passage, or dissolution with ursodeoxycholic acid therapy may reduce the need for cholecystectomy.

Body composition and weight maintenance with a very-low-calorie diet for the treatment of moderate obesity.

We report body composition in 11 moderately obese patients (mean BMI less than 30) treated for 8 wk with a 2530-kJ/d (605-Kcal) diet. Mean weight loss was 9.4 kg. Fat-free mass (FFM) loss of 2.3 kg was 23% of total weight loss and essentially equal to loss of total body water (2.5 L). Body composition was measured by the Futrex-5000 near-infrared technique. We conclude there is no excess loss of FFM in moderately obese patients treated with MNP 70/70, a 70-g protein, 70-g carbohydrate dietary supplement for 8 wk.

Repeated use of the very-low-calorie diet in a structured multidisciplinary weight-management program.

Forty-eight obese patients (mean body mass index = 36.4) were retreated with a very-low-calorie diet (VLCD) at a mean of 104-wk after first VLCD. Mean weight regain was 23 kg or 86% regain of initial loss. Retreatment with VLCD required weekly physician monitoring and indepth psychotherapy group attendance. Five patients (10%) lost an average of 4.55 kg and withdrew within the first 4 wk (group AO. Thirteen patients (27%) lost 13.8 kg over 11.5 wk, an average weight loss of 1.2 kg/wk and enrolled in maintenance (group B). Thirty patients (63%) lost 10.2 kg over 20 wk, an average weight loss of 0.5 kg/wk and did not enroll in the maintenance program (group C). Although weight loss occurs in patients retreated with the VLCD, adherence to the VLCD and commitment to the maintenance program are not optimal.

Cushing's syndrome in pregnancy.

Fertility and childbearing rarely occur in Cushing's syndrome because amenorrhea, oligomenorrhea, infertility, and abortions characterize the disease. Currently, a total of 53 cases of Cushing's syndrome and pregnancy have been reported. When Cushing's syndrome occurs during pregnancy, approximately 56 per cent of the cases are associated with adrenal cortical adenoma or carcinoma. Excluding Cushing's disease, nearly 21 percent of the cases are caused by adrenal carcinoma. The maternal catabolic state of glucocorticoid excess contributes to poor fetal outcome with many of the cases complicated by either fetal wastage or prematurity. However, congenital malformations are not seen more frequently than in normal pregnancy. Pregnancy may or may not influence Cushing's syndrome, but Cushing's syndrome definitely complicates pregnancy.

Deficiency of the insulin, glucose-mediated decrease in serum triglycerides in normolipidemic obese subjects.

The effects of a 6-h insulin, glucose infusion on lipid metabolism were compared in 29 normolipidemic obese and 20 control subjects. Alterations in serum triglycerides (TG), cholesterol, and high-density lipoprotein (HDL) cholesterol were similar within groups when either 40 or 120 mU/m2 per min of regular insulin were infused. Although changes in the HDL cholesterol responses to the insulin, glucose infusions were also similar in obese and control subjects, TG fell more in insulin, glucose-infused controls (35 +/- 4 mg/dl, means +/- s.e.m.) than obese subjects (23 +/- 3) (P less than 0.001). The rate and magnitude of the insulin, glucose-mediated fall in free fatty acids, however, were not different between the two groups. This diminished responsiveness of TG to an insulin, glucose infusion in normotriglyceridemic obese subjects is another manifestation of the insulin resistance of obesity.
