Differences in metabolic and hormonal milieu in diabetic- and alcohol-induced ketoacidosis.

PURPOSE: Diabetic ketoacidosis (DKA) and alcoholic ketoacidosis (AKA) are two medical emergencies characterized by elevated total ketone body concentration. We aimed to determine differences in pathogenesis of ketoacidosis and its metabolic consequences by comparing both at presentation and during treatment, the different metabolic products and hormones involved in the ketoacidotic state. MATERIALS AND METHODS: We studied 12 patients with DKA and 8 patients with AKA. On admission and every 4 hours for 24 hours during treatment, samples were drawn for determination of serum ketone bodies, lactate and pyruvate, insulin, and counterregulatory hormones (glucagon, cortisol, growth hormone, and catecholamines). RESULTS: At presentation, with a similar beta-hydroxybutyrate concentration, patients with DKA had a higher plasma glucose (32 mmol/L vs. 6.6 mmol/L), lower beta-hydroxybutyrate/acetoacetate ratio (3:1 vs. 7:1), and a lower lactate/pyruvate ratio (11:1 vs. 19:1) than patients with AKA (all, P < .01). The mean time to resolve ketoacidosis in patients with AKA (6 +/- 1 hour) was significantly shorter than in patients with DKA (16 +/- 2 hours). At presentation, the mean insulin concentration in patients with DKA and AKA were similarly decreased (7.8 +/- 2 and 10.3 +/- 3 microU/mL, P = not significant [NS]). The mean glucagon level before therapy was 203 +/- 15 pg/mL and 188 +/- pg/mL for patients with DKA and AKA, respectively (P = NS). Levels of cortisol, growth hormone, and epinephrine at presentation and during the first 8 hours of treatment were higher in patients with DKA; however, the difference in these values did not reach statistical significance. During therapy, levels of counterregulatory hormones declined at similar rates and returned to normal values after resolution of ketoacidosis. CONCLUSIONS: Our results indicate that, in addition to a history of diabetes or alcoholism, patients with DKA and AKA differ in their metabolic parameters more than in their hormonal profile. The metabolic profile of DKA is characterized by a higher plasma glucose concentration, and lower beta-hydroxybutyrate to acetoacetate and lactate to pyruvate ratios compared with patients with AKA. The initial hormonal profile in both ketoacidotic states is characterized by similarly decreased insulin levels and elevated levels of counterregulatory hormones.

Bilateral tubo-ovarian abscesses four years after total abdominal hysterectomy.

BACKGROUND: Pelvic inflammatory disease (PID) is a common gynecologic disorder. One known complication of PID is tubo-ovarian abscess (TOA) formation. The predominant theory on TOA formation postulates that an ascending infection from the cervix through the uterus to the fallopian tubes and ovaries results in abscess formation. Other theories include seeding via a hematogenous infection, diverticular disease, and appendicitis. CASE: A 39-year-old female patient with abdominal pain was referred to our institution and was found to have a pelvic mass. After a thorough evaluation, surgical exploration revealed the presence of TOA. No evidence of gastrointestinal disease was present. The patient's history was significant for an uncomplicated total abdominal hysterectomy for benign disease of the uterus four years prior. Abscess cultures grew Streptococcus intermedius. CONCLUSION: This case reports the rare occurrence of TOA in a patient who had undergone an abdominal hysterectomy four years prior to presentation. If the patient reports a surgical history of prior hysterectomy, TOA is often stricken from consideration. Although unlikely, adnexal abscess formation should be considered in the differential diagnosis of a patient with abdominal pain and a pelvic mass, even with a remote history of hysterectomy.
