According to the widely accepted myeloma staging system, the bulk of paraprotein is the main determinant of disease stage. However, myelomatous plasma cells differ considerably in their ability to synthesize and secrete monoclonal paraprotein. We determined plasma cell secreting potential (PCSP) as the amount of M-component, divided by the percentage of marrow plasmacytic infiltration, in 240 patients with myeloma, and correlated our results with chain isotype, plasma cell morphology, severity of bone disease, well-recognized prognostic factors, such as serum LDH, CRP, albumin and beta2-microglobulin, treatment response and overall survival. PCSP was higher in IgG than in other myeloma types, and was an almost constant parameter for each individual patient, in 134/166 cases. A > 10% decrease of PCSP in 26 patients was associated with disease aggressiveness and treatment failure. Patients with MGUS had significantly higher PCSP than those with myeloma of the same chain type. Higher PCSP was associated with stage I, absence of Bence-Jones proteinuria and indolent forms of disease with lower proliferating cell nuclear antigen (PCNA) positivity, serum LDH, alpha2-globulins, CRP and beta2-microglobulin and higher albumin levels. Conversely, patients with immature/plasmablastic morphology and those with severe bone disease had lower PCSP. Good responders to treatment had significantly higher PCSP than moderate and poor responders and PCSP was strongly correlated with overall survival in IgG and IgA myeloma. In conclusion, PCSP reflects the maturation status of myelomatous cells and therefore can be used as a prognostic factor, since patients with high secreting potential represent a lower malignancy group, in comparison to those with a low secreting potential.

We investigated changes in various serum cytokines in a case of systemic lupus erythematosus (SLE) accompanied by hemophagocytic syndrome (HPS). The patient, a 15-year-old male, presented in December 1998 with bilateral salivary gland swelling and a history of fever continuing for more than 10 days. After admission, cerebellar ataxia and clouding of consciousness developed. Laboratory examinations revealed leukopenia, thrombocytopenia, high serum LDH and ferritin, hypercytokinemia, and prominent hemophagocytosis in the bone marrow. Given these findings and positive titers of antinuclear antibody, hypocomplementemia, proteinuria and pericarditis, a diagnosis of HPS with associated SLE was made. The patient was treated with high dose methylprednisolone followed by oral prednisolone and cyclosporine. The patient's clinical symptoms, abnormal blood and urine laboratory data consequently improved, and no recurrence of the symptoms has been documented. However, hemophagocytosis in bone marrow recurred with concomitantly increased serum levels of IL-6 and IL-1 beta. This case indicated that aberrant production of these inflammatory cytokines might be involved in HPS in autoimmune disease.

Thrombotic thrombocytopenic purpura and adult hemolytic-uremic syndrome (TTP/HUS) have a substantial mortality rate even with currently available treatments. Although therapeutic plasma exchange is the recommended treatment of TTP/HUS, this cumbersome procedure may not be available for all patients in an emergency. In this context, plasma infusion may represent an alternative first-line therapy. We compared the effectiveness of high-dose plasma infusion (25-30 mL/kg per day) and therapeutic plasma exchange as first-line treatment of adult TTP/HUS at a single center. Two groups of patients with TTP/HUS were identified according to their initial therapy, that is, high-dose plasma infusion (19 patients) and therapeutic plasma exchange (18 patients). Clinical charts and outcomes were retrospectively analyzed. Endpoints for comparison were the duration of platelet counts below 150 x 10 /L and LDH levels above normal values; the volumes of plasma administered and the duration of treatment; complete remission, relapse, and mortality rates; and treatment-related complications. Patients of the 2 groups had comparable clinical and laboratory features on admission. Sixteen patients achieved complete remission in each group. Median times to recovery of platelet counts and LDH levels were comparable between the 2 groups. Eight patients in the high-dose plasma infusion (HD-PI) group were switched to therapeutic plasma exchange because of fluid overload (6 patients), persistent biologic disturbances (1 patient), or unresponsiveness to high-dose plasma infusion treatment (1 patient). This latter patient had severe TTP/HUS that remained refractory to therapeutic plasma exchange and vincristine, and rapidly died. All 7 remaining patients achieved complete remission with therapeutic plasma exchange. Four patients in the HD-PI group and 3 patients in the therapeutic plasma exchange (TPE) group died. In the HD-PI group, 5 patients experienced a transient nephrotic-range proteinuria during treatment. Main complications in the TPE group were collapse (1 patient) and central venous catheter infection (2 patients) or thrombosis (1 patient). Three patients in each group relapsed. High-dose plasma infusion may be an efficient treatment of TTP/HUS in patients who cannot have early plasma exchange. However, the large volumes of plasma required to reach complete remission may result in fluid overload, which may necessitate subsequent therapeutic plasma exchange.

Neurological and skin involvements usually dominate the clinical presentation of intravascular lymphomatosis (IL), while fever is the most frequent general sign. However, an onset only characterized by fever of unknown origin (FUO) has been rarely reported. We would like to describe a further case of IL, which presented a long-lasting FUO before the diagnosis. At admission, physical examination detected hepatosplenomegaly without lymph nodes enlargement or dermatological or neurological abnormalities. Significant laboratory data included severe anemia, leukopenia, thrombocytopenia, and increased serum LDH. Moreover, a chest CT evidenced bilateral multiple pulmonary infiltrates and pleural effusion. After the development of proteinuria, a diagnosis of large B-cell intravascular lymphoma was made with a renal biopsy 10 months after the onset of the clinical manifestations. So far, more than 100 cases of IL have been reported and the diagnosis often turned out to be difficult, as clinical signs did not point to a lymphoproliferative disorder. This report confirms that FUO is not only frequently associated with IL but that it even marks the real onset of the disease. We are then tempted to conclude that undiagnosed fever is not so rare in IL and if we call it FUO, it is only because diagnosis is necessarily elusive and hence time-consuming.

Extramedullary (EM) localizations at diagnosis or during the course of multiple myeloma (MM) are rare. We conducted a large retrospective study to more accurately describe the clinical and laboratory features of this entity, and the outcome of these manifestations. The charts of 19 eligible patients out of 432 patients with MM were retrieved from the hematology department of the Institut Paoli-Calmettes Cancer Center. Median age was 61 (range: 39-79) with a female/male sex ratio of 8/11. Ten patients were found to have EM and extraosseous tumor at the time of MM diagnosis, and nine patients developed EM tumor during the course of the disease. Neither the stage of the disease, the LDH level, or the type of immunoglobulin (Ig) was found to be associated with the development of EM disease. Patients who developed EM tumor during the course of MM had a lower serum Ig and a higher monoclonal Bence-Jones proteinuria at the diagnosis of MM than patients who presented with EM tumor at diagnosis. Multiple sites were usually involved. Resistance to chemotherapy was frequent and response to thalidomide was poor. Eight out of the 19 patients responded to high-dose chemotherapy. The remaining 11 patients progressed while on therapy. With a median follow-up of 13 months (range: 2-65), six patients are alive, four patients are in partial remission and two patients in present progressive disease. In conclusion, EM tumors are a rare manifestation of MM, with a cumulative incidence of 4.6% of MM. Multiple sites are usually involved. The response to chemotherapy is very poor with a very low response rate to thalidomide. The prognosis is very poor, especially when the diagnosis of EM tumor is concurrent with the diagnosis of MM.

Use-result surveillance was conducted to investigate the safety and efficacy of Acetylcysteine Oral Solution 17.6 % "SENJU" having the indication for the antidote to acetaminophen (Paracetamol) overdose. Ninety six cases (patients) were collected for the safety evaluation, and 13 cases (incidence was 13.5 %) showed 29 adverse drug reactions as follows: 4 cases of nausea; 3 cases of vomiting; 2 cases each of liver dysfunction, headache, abdominal pain, diarrhea, blood bilirubin increased; and one case each of CK increased, anaemia, prothrombin time prolonged, gamma-glutamyltransferase increased, LDH increased, body temperature increased, proteinuria, blood potassium decreased, thrombocytopenia, platelet count increased, white blood cell decreased, and blood amylase increased. One case of severe liver dysfunction which was ameliorated later was found. Neither case showing transitional chronic liver dysfunction, nor case of death was observed. Patient background analysis showed that 79.2% of the total patients was female, and that 28.1% was patients with mental disease. Gastrolavage, active charcoal administration, and extracorporeal removal of toxins were performed in cases of 71.9%, 50.0% and 7.3%, respectively. Those concomitant treatments, however, showed no influence for the incidence of adverse drug reaction or the drug effectiveness. Blood acetaminophen assay was performed in only 43.8% of the total cases. This rate indicates that the medical treatment procedure needs more consideration on the clinical standard for the antidote to acetaminophen overdose and on its practical application.

Renal failure (RF) is a common and severe complication of patients with multiple myeloma (MM). The purpose of our study was to assess the incidence of RF in a contemporary series of newly diagnosed patients with MM, its association with specific clinical and laboratory features, and its impact on patients' outcome. Over the last decade, 756 newly diagnosed symptomatic patients with MM were included in our database. Renal failure, defined as a serum creatinine >or= 2 mg/dl at the time of diagnosis, was seen in 21% of patients. Multiple parameters were associated with RF, but logistic regression analysis showed that RF was independently associated only with International Staging System and Bence Jones proteinuria. The presence of RF was associated with a trend for higher early death rate but with a similar response to primary therapy. The median survival of patients with RF was 19.5 months versus 40.4 months for patients without RF (p < 0.001). Several variables were associated with impaired survival by univariate analysis. When multivariate analysis was performed the independent variables were poor performance status, thrombocytopenia, advanced age, high LDH and elevated serum beta2 microglobulin but not high creatinine. When corrected for stage, renal failure had no impact on survival.

Screening for pulmonary hypertension (pHTN) has not yet become routine in sickle cell disease (SCD), despite clinical evidence of its high prevalence and associated mortality. Our objectives are to identify clinical conditions and laboratory findings predictive of/or associated with pHTN. One hundred twenty-five adult outpatients with Hb SS, SC, SOArab, Sbeta(0), or Sbeta(+) thalassemia, who underwent echocardiography and/or right heart catheterization due to cardiorespiratory symptoms, were studied. pHTN was identified in 36% (28/77) of SS/Sbeta(0) and in 25% (12/48) of SC/SOArab/Sbeta(+) patients studied. In SS/Sbeta(0) patients, pHTN was associated with low hemoglobin, low GFR, increasing age, no history of treatment with hydroxyurea and a history of leg ulcers, with trends for associations with higher total bilirubin, LDH levels, systolic systemic blood pressure, history of avascular necrosis, seizures, and cerebrovascular events. Twelve (40%) of the SS/Sbeta(0) patients with pHTN had >or= 1+ proteinuria. (P<0.039). The presence of proteinuria correlated with lower GFR and had a high positive predictive value (0.60) for pHTN in subjects with SS/Sbeta(0). The data also provided evidence that pHTN in this population is associated with right heart failure, with echocardiographic evidence of right ventricle enlargement and pericardial effusion. This study confirmed that even relatively mild elevations in pulmonary pressure are associated with high prospective mortality (hazard ratio: 15.9). We concluded that pHTN has a high prevalence in all Hb S related syndromes and is associated with increased mortality in SS/Sbeta(0). Kidney dysfunction, as indicated by proteinuria or decreased GFR, also represents sufficient reason to screen for pHTN.

Indications in cardiovascular and respiratory procedures, osteoporosis, Diabetes Mellitus and obesity and their specified actions with cardiorespiratory physical activity require parameters which are based on consumption of energy, on effort applied in the biomechanical kinetic activity and kinematics. Using three models of physical activity: 1. Aerobic resistance exercise; 2. Strength-Resistance; 3. Chronic overexertion. The results of neutrophils, proteinuria, LDH, CPK, GOT, GPT and blood iron levels correlate statistically with the results of trace minerals: Zinc and Copper.

We report the case of a 28-year-old nulliparous woman who presented at 36 weeks' gestation with preeclampsia: high blood pressure, proteinuria and edema. Serum test results were normal and platelet count was 155 x 10(3)/mm(3). After 30 h the patient initiated severe epigastric pain and vomits, and lab tests presented a slight increase in liver enzymes. The platelet count remained above 150,000/microL. Cesarean section (CS) was performed. Six hours after CS, she developed a hypovolemic shock and lab tests became increasingly abnormal (liver enzymes increased sharply and hemoglobin and platelet count decreased sharply). Abdominal ultrasound showed suggestive signs of hepatic rupture. The patient was stabilized and exploratory laparotomy was performed. Perihepatic packing was applied. The patient was discharged after 25 days of admission (15 days at the ICU) and three explorative laparotomies. This case highlights the unpredictability of this event based on the changes of liver enzyme values, LDH and platelet count. These changes only occurred when the rupture had already occurred and the patient was in hypovolemic shock.
