In September 1999, a 56-year-old butcher was admitted to the General Hospital in Zadar because of fever, headache, severe pain in the calf muscles and thighs, conjunctivitis, rash, hepatomegaly and jaundice. The initial diagnosis was septic shock, and the patient was admitted to the internal medicine ward. Microscopic agglutination test showed a fourfold rise of antibodies to Leptospira sejroe in the three serum samples. These serologic findings and laboratory findings of leukocytosis, thrombocytopenia, increased serum aminotransferases, blood urea nitrogen and creatinine, proteinuria and leukocyturia indicated that Leptospira sejroe was the etiologic agent of the disease in the patient presented.

A retrospective analysis was performed on 263 consecutive patients aged over 60 with de novo acute myeloid leukemia (AML) diagnosed in a single institution between 1979 and 1998. Eighty-nine patients (33%) received only palliative treatment, while 174 patients (67%) were treated with different intensive chemotherapy regimens. The 5- and 10-year overall survival (OS) for the whole series was 7.7+/-1.2 and 4.3+/-1.6%, respectively. For patients receiving chemotherapy, OS was 10.5+/-2.5 and 7+/-2.6%, while for those patients receiving supportive treatment it was 1.1+/-1.1 and 0%, respectively (P=0.002). Within the group of patients receiving chemotherapy, the complete remission (CR) rate was 46%; treatment failure rate was 54% (36% due to treatment-related mortality and 18% due to resistant disease). Variables influencing CR rate were FAB subtype, CD7 positivity, chemotherapy regimen, creatinine level, hepatomegaly, and period of diagnosis. Median disease-free survival (DFS) duration was 8.4 months with a probability of being disease-free at 10 years of 10+/-5%. There were no significant differences in DFS according to age. According to the period of diagnosis (1979-1986 vs. 1987-1998), improvements in the CR rate (27 vs. 56%, P=0.0002), and OS (10.9 vs. 15.7 months, P=0.0007) were observed. This large single-center study of unselected de novo AML elderly patients substantiates the progressive improvement achieved in the management of elderly patients with AML, probably due to an improvement in supportive care and the administration of conventional induction chemotherapy.

An increase of angiogenesis has been shown in idiopathic myelofibrosis with myeloid metaplasia (MMM) by microvessel density count method but evaluation of circulating angiogenic factors is still incomplete. In 31 patients affected by MMM and in 12 healthy subjects we evaluated the serum levels of VEGF (vascular endothelial growth factor) and correlated VEGF with clinical and laboratory features of disease. We found that MMM patients had circulating VEGF concentrations much higher than controls (Median 1208 ng/ml vs 138 ng/ml, P < 0.0001). No correlation was found between VEGF and Hb, WBC, PLT, LDH, creatinine, bone marrow cellularity, fibrosis, splenomegaly, hepatomegaly, and therapy. However, in the subgroup of patients with a normal or low VEGF concentration, a direct correlation between VEGF and platelet count (r = 0.90, P = 0.002) was detected. Moreover, patients with a platelet count < 300 x 10(9)/l had VEGF serum levels lower than patients with a higher PLT count (median VEGF 864 vs 1557 pg/ml, P = 0.001). In six patients and in eight controls we also had the opportunity to measure VEGF in the plasma and we calculated that VEGF concentration was much higher in platelet-rich than in platelet-poor plasma and that platetets of MMM patients contained four times more VEGF than those of healthy controls. These results indicate that VEGF is overproduced in MMM, thus confirming an increased angiogenic activity. Platelets are probably a major source of VEGF in MMM but not the only one.

Spontaneous amyloidosis was diagnosed in 11 male and 1 female chimpanzees and confirmed histologically and immunohistochemically. The chimpanzees were > or = 15 years of age when first diagnosed and averaged 22.4 years of age. The average survival time after diagnosis of systemic amyloidosis was 1.86 years with a standard deviation of 4.06 years (n = 7). The chimpanzees with amyloidosis were asymptomatic except for hepatomegaly, which became more detectable with age. Significant increases in clinical chemistry values, as compared with referenced normals and established normals, of blood urea nitrogen (BUN), asparate aminotransferase (AST), gamma-glutamyltransferase (GGT), globulin, total protein, creatinine phosphokinase (CPK), sedimentation rate, and triglycerides were found in animals 7 years of age or older with amyloidosis. These serum chemistry values, while increased in chimpanzees with amyloidosis, were generally within normal limits. Immunohistochemistry for both amyloid A protein and amyloid P component-labeled extracellular amyloid in all chimpanzees with amyloidosis was determined. Amyloid was deposited primarily in the liver. Amyloidosis in the chimpanzee is a chronic, intractable, progressive, fatal disease, and appears to be similar to secondary amy loidosis in other species.

Primary plasma cell leukemia (PPCL) is a rare form of disease accounting for 1-2 percent of myelomas. Between September 1990 and November 2000, among 540 patients with myeloma studied, 24 fulfilled the criteria of PPCL (4.4 percent). We found high frequencies of female patients (62 percent), Bence Jones proteinuria (79 percent), anemia (88 percent), bleeding (54 percent), confusional syndrome (42 percent), weight loss (71 percent), hepatomegaly (25 percent), splenomegaly (21 percent), leukocytosis (62 percent), and thrombocytopenia (71 percent). High serum levels of creatinine, calcium, lactate dehydrogenase (LDH), and beta(2)-microglobulin were detected in 50 percent, 37 percent, 58 percent, and 71 percent, respectively. Four patients were treated with vincristine, melphalan, cyclophosphamide, prednisone, and adriamycin (VMCPA), 12 with vincristine, adriamycin, and dexamethasone (VAD), and 8 with M-80 (oral melphalan 80 mg/m(2) plus dexamethasone 40 mg/m(2)). There was a trend toward lower values of Karnofsky score (P=0.07) and higher values of LDH (P=0.2) in the VAD group. Other clinical characteristics were comparable among the three groups. Complete plus partial responses were achieved in one and six patients treated with VMCPA and M-80, respectively. All patients treated with VAD failed to respond to treatment. Patients receiving the M-80 regimen experienced higher platelet toxicity (P=0.05), vomiting (P<0.0003), and mucositis. Also, the need for red blood cell transfusions was higher in the M-80 group. Median overall survival was 60 days. Overall survival was better in patients achieving complete or partial response. In conclusion, our study illustrates that intermediate doses of melphalan plus dexamethasone are an effective chemotherapy regimen for this aggressive disease. Response to treatment is the only prognostic factor for survival in these patients.

A descriptive study was carried out in 104 patients with Plasmodium vivax malaria, from the region of Turbo (Antioquia, Colombia). Clinical features and levels of hemoglobin, glycemia, serum bilirubin, alanine-aminotransferase (ALT), aspartate-aminotransferase (AST), creatinine and complete blood cell profile were established. 65% of the studied individuals were men and their mean age was 23. Of all individuals 59% had lived in the region for > 1 year and 91% were resident in the rural area. 42% were farmers and 35% had a history of malaria. The mean parasitaemia was 5865 parasites/mm3. The evolution of the disease was short (average of 4.0 days). Fever, headache and chills were observed simultaneously in 91% of the cases while the most frequent signs were palmar pallor (46%), jaundice (15%), hepatomegaly (17%), and spleen enlargement (12%). Anemia was found in 39% of the women and in 51% of the men, 8% of individuals had thrombocytopaenia and 41% had hypoglycemia.

Generalized lipodystrophy is characterized by adipose tissue absence, hypoleptinemia, hypertriglyceridemia, insulin resistance, diabetes, hepatomegaly, and nonalcoholic steatohepatitis. In the course of recruiting patients for treatment with recombinant leptin, we were struck by the frequency and severity of proteinuria. We evaluated 25 patients with generalized lipodystrophy. Eighteen were treated with recombinant leptin, and we have followed 15 on leptin for 4-36 months. We followed renal parameters at baseline and during follow-up visits. Renal biopsies were performed as clinically indicated. At baseline, 22 of 25 patients (88%) had elevated urine albumin excretion (>30 mg/24 h), 15 (60%) had macroalbuminuria (>300 mg/24 h), and five (20%) had nephrotic-range proteinuria (>3500 mg/24 h). Twenty-three (92%) had elevated creatinine clearance (>125 ml/min.1.73 m(2)). Eleven of 15 patients (73%) treated with recombinant leptin exhibited reduction in proteinuria, associated with reduction of hyperfiltration. Four patients who did not improve are discussed individually. Renal biopsy findings were remarkable for focal segmental glomerulosclerosis in four patients, membranoproliferative glomerulonephritis in two patients, and diabetic nephropathy in one patient. In conclusion, generalized lipodystrophy is associated with proteinuria and unique renal pathologies, including focal segmental glomerulosclerosis and membranoproliferative glomerulonephritis. The majority treated with recombinant leptin demonstrated reduction in proteinuria and hyperfiltration.

A 73-year-old woman was presented with altered mental status and disorientation. She was diabetic and hypertensive, and she had experienced an ischemic cerebrovascular accident 3 years ago. Physical examination revealed the findings of chronic obstructive pulmonary disease, cor pulmonale and congestive heart failure. Hepatomegaly, splenomegaly and ascites were found and might be associated with postsinusoidal portal hypertension secondary to congestive heart failure. Laboratory tests showed uremia, lymphocytosis and thrombocytopenia. Neurologic findings were related with uremia and hypoxia. Multiple pathologic lymphadenopathies were seen in abdominal ultrasonography and thoracic computed tomography. Bone marrow histology indicated chronic lymphocytic leukaemia (CLL). The reason for acute renal failure was leukaemic infiltration of the kidneys due to CLL that was shown with renal biopsy. Blood urea nitrogen (BUN) and serum creatinine responded well to cyclophosphamide and methyl prednisolone treatment. In CLL, direct renal involvement is frequently seen in autopsy studies especially in advanced disease, however, renal failure due to leukaemic infiltration is extremely rare.

The major pathology in sickle cell anaemia (SCA) is sickling of red cells due to the precipitation of reduced haemoglobin. We report our experience with extract of Cajanus cajan as a possible antisickling agent by determining changes, if any, in clinical and laboratory features of the disease in patients given the extract in a single-blind placebo-controlled study. One hundred patients with steady-state SCA were randomized into treatment and placebo arms. The extract/placebo were administered twice daily to the subjects. Weight, hepatosplenomegaly, blood levels of biliurubin, urea, creatinine, and packed cell volume (PCV) were monitored over a 6-month period. Recall episodes of pain 6 months before enrolment were compared with episodes of pains recorded during the treatment period. Twenty-six cases (55.3 per cent) had hepatomegaly on enrolment. This significantly reduced to 33.3 per cent at 6 months (p = 0.03); but increased in the placebo arm (p > 0.05). The total number of recall painful episodes in cases was 207 (mean 4.4 +/- 10.3 (SD), range 0-60) and fell to 191 (mean 4.2 +/- 4.4 (SD), range 0-16); p = 0.03. Episodes of pain increased from 109 in controls (mean 2.6 +/- 5.0 (SD), range 0-26) to 164 (mean 3.9 +/- 4.3 (SD), range 0-22); p = 0.01. Mean PCV in the cases showed no appreciable changes (p = 0.1) but there was a significant increase in the controls (p = 0.02). In conclusion, the extract may cause a reduction of painful crises and may ameliorate the adverse effects of sickle cell anaemia on the liver. The mechanism of action remains to be determined.

Adefovir is classified as a nucleotide reverse transcriptase inhibitor because it acts by inhibiting hepatitis B virus DNA polymerase (reverse transcriptase) and causing DNA chain termination after its incorporation into the viral DNA. Adefovir dipivoxil is indicated for the treatment of chronic hepatitis B in adults with evidence of active viral replication and either evidence of persistent elevations in serum aminotransferases (alanine [ALT] or aspartate [AST]) or histologically active disease. It is useful in the treatment of patients with either hepatitis B e antigen-positive or -negative chronic hepatitis B. The recommended adefovir dipivoxil dose in the treatment of chronic hepatitis B in patients with adequate renal function is 10 mg once daily. Adefovir dipivoxil therapy can reduce viral load, improve ALT, and produce histologic improvement in patients with chronic hepatitis B. Improvements are generally seen within the first few weeks of therapy and have shown persistence up to at least 3 years with continued therapy. Therapy with adefovir dipivoxil is generally well tolerated. However, nephrotoxicity is a risk with adefovir therapy, especially in patients receiving higher doses (30-120 mg/d). Patients should have their renal function monitored closely throughout therapy and may require an adjustment in dose relative to changes in the creatinine clearance. Lactic acidosis and severe hepatomegaly with steatosis may also occur during therapy.
