The influence of extreme body weight on clinical outcome of patients with venous thromboembolism: findings from a prospective registry (RIETE).

BACKGROUND: Data evaluating the safety of using weight-based dosing of low-molecular-weight heparin (LMWH) in either underweight or obese patients with venous thromboembolism (VTE) are limited. Thus, recommendations based on evidence from clinical trials might not be suitable for patients with extreme body weight. PATIENTS AND METHODS: Patients with objectively confirmed, symptomatic acute VTE are consecutively enrolled into the Registro Informatizado de la Enfermedad TromboEmbólica (RIETE) registry. For this analysis, data from patients in the following ranges of body weight were examined: <50, 50-100, and >100 kg. Patient characteristics, underlying conditions, treatment schedules and clinical outcomes during the first 15 days of treatment were compared. RESULTS: As of August 2004, 8845 patients with acute VTE were enrolled from 94 participating centers. Of these, 169 (1.9%) weighed <50 kg, 8382 (95%) weighed 50-100 kg and 294 (3.3%) weighed >100 kg. Patients weighing <50 kg were more commonly females, were taking non-steriodal antiinflammatory drugs (NSAIDs), and had severe underlying diseases more often than patients weighing 50-100 kg. Their incidence of overall bleeding complications was significantly higher than in patients weighing 50-100 kg (odds ratio 2.2; 95% CI: 1.2-4.0). Patients weighing >100 kg were younger, most commonly males, and had cancer less often than those weighing 50-100 kg. Incidences of recurrent VTE, fatal pulmonary embolism or major bleeding complications were similar in both groups. CONCLUSIONS: Patients with VTE weighing <50 kg have a significantly higher rate of bleeding complications. The clinical outcome of patients weighing over 100 kg was not significantly different from that in patients weighing 50-100 kg.

Differential diagnosis between community-acquired pneumonia and non-pneumonia diseases of the chest in the emergency ward.

Background: The differential diagnosis of community-acquired pneumonia and some non-pneumonia diseases involving the chest may sometimes be cumbersome. Adding some objective variables to the diagnostic strategy may be helpful.We evaluated the main objective variables that are usually available in the emergency ward and that may be valuable in this differential diagnosis. Methods: We recorded epidemiological, clinical, and analytical data, as well as that obtained from physical examination, from 284 consecutive patients diagnosed in the emergency ward as having community-acquired pneumonia. The diagnosis was reviewed by the investigators applying pre-set diagnostic criteria. Statistical analysis was then performed comparing data from patients with a definitive diagnosis of community-acquired pneumonia with those with a final diagnosis of non-pneumonia disease excluding acute exacerbations of chronic bronchitis. Results: In the univariate analysis, C-reactive protein (difference of means 93 mg/l; 95% C.I. 47, 140), erythrocyte sedimentation rate (d.m. 19 mm/h; 95% C.I. 3, 35), leukocyte count (d.m. 3.5x10(9)/l; 95% C.I. 0.5, 6.4), and temperature (d.m. 0.5 degrees C; 95% C.I. 0.1, 0.9) discriminated between community-acquired pneumonia and non-pneumonia diseases. In the multivariate analysis, only C-reactive protein remained in the equation. Conclusions: C-reactive protein, erythrocyte sedimentation rate, leukocyte count, and temperature were measurable variables that proved to be useful in the differential diagnosis between community-acquired pneumonia and non-pneumonia diseases. C-reactive protein appears to be the most suitable for this purpose.

Pulmonary amyloidosis and unusual lung involvement in SLE.

The association of systemic lupus erythematosus (SLE) with amyloidosis is exceptional. We present a 37-year-old patient who was diagnosed five months earlier for SLE. She developed an acute episode of chest pain, cough and dyspnoea. Hypoxemia and obstructive changes in respiratory tests were present. The chest X-ray was repeatedly normal. Open lung biopsy revealed lupus pneumonitis with positive stain for immunoglobulins and complement, bronchiolitis obliterans, and pulmonary amyloidosis.

Peripheral neuropathy in essential mixed cryoglobulinemia.

Sixteen patients with essential mixed cryoglobulinemia were studied and followed up clinically and electrophysiologically for 4.2 years. Peripheral neuropathy was diagnosed in seven cases. Five of these patients had distal symmetrical sensorimotor polyneuropathy. Nerve conduction velocities were normal and therefore indicative of pure axonal neuropathy. Sural nerve biopsy showed moderate loss of myelinated axons in two patients and severe loss in one. This patient also had necrotizing arteritis. The remaining two had both clinical and electrophysiologic signs of overlapping mononeuritis multiplex with severe denervation in the territory of the involved nerves, but normal conduction velocities. Sural nerve biopsy in one of these two patients showed marked loss of myelinated fibers and signs of vasculitis. Two types of neuropathy were noted: (1) a mild distal neuropathy with relatively minor neurologic deficit, probably due to vasa nervorum microcirculation occlusion caused by intravascular deposits of cryoglobulins and (2) a severe distal symmetrical sensorimotor neuropathy or overlapping mononeuritis multiplex, associated with necrotizing vasculitis.
