Introduction: Current guidelines recommend the use of anticoagulant therapy in patients with symptomatic splanchnic vein thrombosis (SVT) and suggest no routine anticoagulation in those with incidental SVT.

Methods: We used the RIETE (Registro Informatizado Enfermedad Trombo Embólica) registry to assess the rate and severity of symptomatic venous thromboembolism (VTE) recurrences and major bleeding events appearing during the course of anticoagulation in patients with symptomatic or incidental SVT.

Results: In March 2017, 521 patients with SVT were recruited. Of them, 212 (41%) presented with symptomatic SVT and 309 had incidental SVT. Most (93%) patients received anticoagulant therapy (median, 147 days). During the course of anticoagulation, 20 patients developed symptomatic VTE recurrences (none died) and 26 had major bleeding (fatal bleeding, 5). On multivariable analysis, patients with incidental SVT had a non-significantly higher risk for symptomatic VTE recurrences (adjusted hazard ratio [HR]: 2.04; 95%CI: 0.71-5.88) and a similar risk for major bleeding (HR: 1.12; 95%CI: 0.47-2.63) than those with symptomatic SVT. Active cancer was associated with at increased risk for VTE recurrences (HR: 3.06; 95%CI: 1.14-8.17) and anaemia (HR: 4.11; 95%CI: 1.45-11.6) or abnormal prothrombin time (HR: 4.10; 95%CI: 1.68-10.1) were associated with at increased risk for major bleeding.

Conclusions: The rates of recurrent SVT and major bleeding were similar between patients with incidental or symptomatic SVT. Because the severity of bleeding complications during anticoagulation may outweigh the severity of VTE recurrences in both groups, further studies should identify those SVT patients who benefit from anticoagulant therapy.

All-cause mortality in treated HIV-infected adults with CD4 ≥500/mm3 compared with the general population: evidence from a large European observational cohort collaboration.

Int J Epidemiol 2012 Apr 28;41(2):433-45. Epub 2011 Nov 28.

INSERM, U897, ISPED, Université Bordeaux Segalen, Bordeaux, France.

Background: Using data from a large European collaborative study, we aimed to identify the circumstances in which treated HIV-infected individuals will experience similar mortality rates to those of the general population.

Methods: Adults were eligible if they initiated combination anti-retroviral treatment (cART) between 1998 and 2008 and had one prior CD4 measurement within 6 months. Standardized mortality ratios (SMRs) and excess mortality rates compared with the general population were estimated using Poisson regression. Periods of follow-up were classified according to the current CD4 count.

Results: Of the 80 642 individuals, 70% were men, 16% were injecting drug users (IDUs), the median age was 37 years, median CD4 count 225/mm(3) at cART initiation and median follow-up was 3.5 years. The overall mortality rate was 1.2/100 person-years (PY) (men: 1.3, women: 0.9), 4.2 times as high as that in the general population (SMR for men: 3.8, for women: 7.4). Among 35 316 individuals with a CD4 count ≥500/mm(3), the mortality rate was 0.37/100 PY (SMR 1.5); mortality rates were similar to those of the general population in non-IDU men [SMR 0.9, 95% confidence interval (95% CI) 0.7-1.3] and, after 3 years, in women (SMR 1.1, 95% CI 0.7-1.7). Mortality rates in IDUs remained elevated, though a trend to decrease with longer durations with high CD4 count was seen. A prior AIDS diagnosis was associated with higher mortality.

Conclusions: Mortality patterns in most non-IDU HIV-infected individuals with high CD4 counts on cART are similar to those in the general population. The persistent role of a prior AIDS diagnosis underlines the importance of early diagnosis of HIV infection.

Multiple myeloma and hyperammonemic encephalopathy: review of 27 cases.

Clin Lymphoma Myeloma 2008 Dec;8(6):363-9

Department of Internal Medicine, Hospital Universitario de Bellvitge, c/ Feixa Llarga s/n, L'Hospitalet de Llobregat, Barcelona, Spain.

Hyperammonemic encephalopathy is a rarely reported complication of multiple myeloma (MM). We describe an illustrative case of hyperammonemia in the setting of an immunoglobulin (Ig) D-lambda MM, and perform a systematic review of the English-written literature. Our search yielded 26 more cases. Median age was 64 years, and 54% of patients were male. All presented with progressive impairment of their level of consciousness. Median ammonium concentration was 109 micromol/L (interquartile range, 73-149 micromol/L). Most were IgA type (10 cases), and there were 2 cases of IgD type. Most cases were aggressive or chemotherapy-resistant forms of MM. Eight patients were diagnosed with MM at the same time as the episode of hyperammonemia. Only 1 patient had signs of portal hypertension as a result of concomitant hyperdynamic heart failure. Determination of amino acid in 10 patients showed high levels of glycine, low levels of tyrosine, and a low Fischer ratio. Two patients did not receive chemotherapy and died. Twenty-two out of 25 patients who received chemotherapy against MM showed a decrease in ammonium blood concentration, and of those, 15 survived the episode (68%). Overall mortality was 44%. In conclusion, hyperammonemia is a severe complication of MM, associated with a high mortality. It should be considered in any patient with MM and a low level of consciousness. Chemotherapy directed against MM seems to be the most effective measure in order to achieve normal ammonium levels and clinical improvement.

Sarcoidosis and autoimmune thyroid disease. A case series of ten patients.

Sarcoidosis Vasc Diffuse Lung Dis 2007 Sep;24(2):148-52

Internal Medicine Service, Institut d'Investigació Biomèdica de Bellvitge, Bellvitge University Hospital, University of Barcelona, Spain.

Background: Sarcoidosis coexisting with autoimmune disorders, especially with autoimmune thyroid disease (ATD), has been previously described and a common immunopathogenesis has been proposed. We report a series of ten new cases of this association from a large series of patients with sarcoidosis.

Methods: The clinical records of patients diagnosed with sarcoidosis between 1984 and 2006 in the Bellvitge University Hospital were reviewed, and those who were also diagnosed as having ATD were selected. A review of the literature was performed as well.

Results: Ten out of 348 (2.9%) patients with sarcoidosis were identified as having ATD. Sarcoidosis presented as Löfgren's syndrome in 8 patients. Three patients developed Graves' disease, 6 Hashimoto's thyroiditis with hypothyroidism and one had postpartum thyroiditis. In one case, ATD had developed 15 years before sarcoidosis. In the remaining nine cases, sarcoidosis preceded between 4 months to 17 years the development of ATD. In 3 of these cases, sarcoidosis was active when ATD was diagnosed. In one patient, Graves' disease developed immediately after the administration of potassium iodide to treat erythema nodosum.

Conclusions: Sarcoidosis may be associated with ATD at some time of its evolution, either as hyperthyroidism or hypothyroidism. Usually, ATD does not develop during the period of activity of sarcoidosis. We suggest considering personal and family past history of thyroid disease before administering potassium iodide for erythema nodosum in patients with sarcoidosis, as it could trigger hyperthyroidism, especially in patients with iodine deficiency.
