Hydrosalpinx and IVF outcome: a prospective, randomized multicentre trial in Scandinavia on salpingectomy prior to IVF.

Many retrospective studies have shown that hydrosalpinx is associated with poor in-vitro fertilization (IVF) outcome. The mechanism of the actual cause is not yet fully understood. A clinical practice of performing salpingectomy before IVF has developed, without any evidence from prospective trials. The aim of the present prospective randomized trial was to test if a salpingectomy prior to IVF was effective in terms of increased pregnancy rates. Patients with hydrosalpinx were randomized to either a laparoscopic salpingectomy or no intervention before IVF. A total of 204 patients was available for an intention-to-treat analysis and 192 actually started IVF. Clinical pregnancy rates per included patient were 36.6% in the salpingectomy group and 23.9% in the non-intervention group (not significant, P = 0.067) and the ensuing delivery rates were 28.6% and 16.3% (P = 0.045). The corresponding delivery rates per transfer cycle were 29.5% versus 17. 5% (not significant, P = 0.083). A subgroup analysis revealed significant differences in favour of salpingectomy, in implantation rates in patients with bilateral hydrosalpinges (25.6% versus 12.3%, P = 0.038) and in clinical pregnancy rates (45.7% versus 22.5%, P = 0.029) and delivery rates (40.0% versus 17.5%, P = 0.038) in patients with ultrasound visible hydrosalpinges. The delivery rate was increased 3.5-fold in patients with bilateral hydrosalpinges visible on ultrasound (P = 0.019).

Countrywide epidemics of Chlamydia pneumoniae, strain TWAR, in Scandinavia, 1981-1983.

There was a large increase in incidence of reported cases of ornithosis in Norway, Sweden, and Denmark in 1981-1983. Serologic evidence indicated that the epidemic was caused by the newly described Chlamydia organism, C. pneumoniae, strain TWAR. When serum samples that had been shown to contain Chlamydia complement fixing antibodies were tested by the microimmunofluorescence method with TWAR antigen, 49%-71% showed evidence of current TWAR infection during the epidemic years compared with 10%-20% in nonepidemic years.

Autoimmunity and susceptibility to Hodgkin lymphoma: a population-based case-control study in Scandinavia.

BACKGROUND: Personal history of autoimmune diseases is consistently associated with increased risk of non-Hodgkin lymphoma. In contrast, there are limited data on risk of Hodgkin lymphoma following autoimmune diseases and almost no data addressing whether there is a familial association between the conditions. METHODS: Using population-based linked registry data from Sweden and Denmark, 32 separate autoimmune and related conditions were identified from hospital diagnoses in 7476 case subjects with Hodgkin lymphoma, 18,573 matched control subjects, and more than 86,000 first-degree relatives of case and control subjects. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) as measures of relative risks for each condition using logistic regression and also applied multivariable hierarchical regression models. All P values are two-sided. RESULTS: We found statistically significantly increased risks of Hodgkin lymphoma associated with personal histories of several autoimmune conditions, including rheumatoid arthritis (OR = 2.7, 95% CI = 1.9 to 4.0), systemic lupus erythematosus (OR = 5.8, 95% CI = 2.2 to 15.1), sarcoidosis (OR = 14.1, 95% CI = 5.4 to 36.8), and immune thrombocytopenic purpura (OR = infinity, P = .002). A statistically significant increase in risk of Hodgkin lymphoma was associated with family histories of sarcoidosis (OR = 1.8, 95% CI = 1.01 to 3.1) and ulcerative colitis (OR = 1.6, 95% CI = 1.02 to 2.6). CONCLUSIONS: Personal or family history of certain autoimmune conditions was strongly associated with increased risk of Hodgkin lymphoma. The association between both personal and family histories of sarcoidosis and a statistically significantly increased risk of Hodgkin lymphoma suggests shared susceptibility for these conditions.

Relative influence of insulin resistance versus blood pressure on vascular changes in longstanding hypertension. ICARUS, a LIFE sub study. Insulin Carotids US Scandinavia.

BACKGROUND: Insulin resistance is associated with hypertension. The relative influences of hyperinsulinaemia and high blood pressure on vascular hypertrophy and carotid distensibility is unclear in patients with longstanding hypertension. METHODS: In 88 unmedicated patients with stage II-III hypertension and left ventricular hypertrophy on electrocardiogram we measured blood pressure, minimal forearm vascular resistance (MFVR) using plethysmography, intima-media thickness (IMT) and the wall distensibility of the common carotid arteries using ultrasound, and insulin sensitivity using a 2-h isoglycaemic hyperinsulinaemic clamp. RESULTS: IMT was positively correlated to systolic blood pressure (r= 0.26, P < 0.05), whole body glucose uptake index (M/IG; r= 0.22, P< 0.05), age (r= 0.24, P< 0.05) and negatively correlated to body mass index (r= -0.24, P < 0.05); IMT did not correlate to fasting serum insulin (r= -0.14, NS). In men (n = 64) MFVR was positively correlated to systolic blood pressure (r = 0.30, P < 0.05), but was unrelated to M/G and serum insulin. The distensibility of the common carotid arteries was negatively correlated to systolic blood pressure (r = -0.40, P< 0.001) and in untreated patients (n = 22) positively correlated to M/IG (r = 0.47, P < 0.05). CONCLUSIONS: High systolic blood pressure was related to vascular hypertrophy, whereas hyperinsulinaemia and insulin resistance were not, suggesting that longstanding high blood pressure is a far more important determinant for structural vascular changes than insulin resistance at this stage of the hypertensive disease. However, hyperinsulinaemia and insulin resistance were associated with low distensibility of the common carotid arteries in the subgroup of never treated hypertensive patients.

Ischemic heart disease--major cause of death and graft loss after renal transplantation in Scandinavia.

Causes of graft loss and death were studied in 1347 recipients of primary renal transplants followed for 5 years after transplantation irrespective of graft function. Immunosuppression consisted of high or medium dose CsA and prednisolone or low dose CsA and prednisolone and azathioprine. In recipients of cadaver grafts, death with a functioning transplant was more common than graft rejection after the first posttransplant year, accounting for 49% and 41% of the graft losses, respectively. Of deaths with a functioning graft, 53% were due to ischemic heart disease (IHD) and 10% were due to other vascular disease. In the 55- to 64-year-old age group, the risk of death from IHD was 6.4 times higher in the transplanted nondiabetic patients, 8.6 times higher in the dialysis patients (European Dialysis and Transplant Association figures), and 20.8 times higher in the transplanted diabetic patients than in the general population (national figures). A multivariate Cox regression analysis showed that old age, diabetes mellitus, occurrence of acute rejection, pretransplant transfusions, delayed onset of graft function, and male gender were significant for death in IHD. We conclude that, in comparison to reports from other regions, Scandinavian renal transplant recipients are at high risk of dying of IHD. Future advances in long-term renal graft survival will depend largely on the success of preventing myocardial infarction and death in this patient population.

Drug and alcohol use among patients admitted to a Danish trauma centre: a prospective study from a regional trauma centre in Scandinavia.

OBJECTIVES: The incidence of drug and alcohol use is unknown among Danish trauma patients, and has not been thoroughly investigated in Europe. METHODS: Patients admitted to the regional trauma centre in Aarhus, Denmark, were prospectively screened by blood and urine tests for the presence of alcohol, and legal and illicit drugs. The correlation with the Injury Severity Score, hospitalization time, and mortality after drug or alcohol intake was investigated. RESULTS: A quarter of all patients admitted in 1999 and 2000 had an alcohol level exceeding the national legal driving limit of 50 mg/dl, and one or more drugs were found in one in five patients. The presence of any drug or alcohol correlated positively with the Injury Severity Score, whereas alcohol level, hospitalization time, and mortality did not correlate. CONCLUSION: The rate of trauma patients with a blood serum level of alcohol greater than 100 mg/dl was similar to a previous European study and to US studies. The prevalence of drugs was less, and benzodiazepines were the most used group of drugs in our study. The routine screening of Danish trauma patients in order to implement preventative measures may be beneficial.
