Exacerbating factors of tuberculosis were evaluated from the viewpoint of intractability of the disease including the effectiveness of chemotherapy by comparing patients with intractable tuberculosis and those with nonintractable tuberculosis. Of the patients aged 30 years or above admitted to our hospital for the initial episode of tuberculosis, 42 patients with intractable tuberculosis and 247 controls were compared. No difference was observed between the two groups in life-style factors such as smoking, drinking, and living alone or complications such as diabetes mellitus and cerebrospinal diseases. In the refractory group, a poor general condition with fever and body weight losses on admission, massive discharge of tubercle bacillus, and delayed diagnosis and treatment were frequently observed. Also, patients with a lymphocyte count of 500/mm3 or less such as those with anemia, hypoproteinemia/hypoalbuminemia, high LDH and CRP levels, and a low cholinesterase level were significantly more frequent, and resistant bacteria were detected more frequently in this group.

The ability of vitamins C, E and K to inhibit enzymes directly has been investigated. It was found that vitamin E and some analogs and menadione (vitamin K3) inhibited several enzymes irreversibility at concentrations below one millimolar. Ascorbate inhibits rabbit muscle 6-phosphofructokinase (MPFK-1; EC 2.7.1.11), muscle type LDH (EC 1.1.1.27), and muscle AK (EC 2.7.4.3) at low concentrations that do not inhibit equivalent liver isozymes. Ascorbate Ki values for muscle-type LDH and heart-type LDH isozymes are 0.007 and 3 mM, respectively. The ascorbate Ki value for rabbit skeletal muscle PFK-1 is 0.16 mM; liver PFK-I is not inhibited by ascorbate. Dehydroascorbate does not inhibit any enzyme at ascorbate concentrations normally found in cells. All ascorbate inhibitions are completely reactivated or nearly so by L-ascorbate oxidase, CYS, GSH, or DTT. We propose a hypothesis that ascorbate facilitates glycogen storage in muscle by inhibiting glycolysis. The relationship between ascorbate metabolism and diabetes is discussed.

The study was performed on 31 diabetic patients of both sexes, divided in 2 groups: group I--17 patients with insulin-dependent diabetes (IDDM) and group II--14 patients with noninsulin-dependent diabetes (NIDDM) and compared with a control group of 16 non-diabetic subjects. Mixed saliva was sampled without stimulation during 2 periods of the day: 07:30-08:00 before breakfast and 17:30-18:00 before dinner. We determined: salivary flow rate, pH with Merck indicator and, after homogenization, the thiocianat with the FeCl3 method and LDH activity (the Norbert method adapted in our laboratory for saliva). Our study showed the same diurnal changes in flow rate and salivary pH in both diabetic and control groups: minimal values in the morning and maximal ones in the afternoon. In non-smoking diabetic patients the salivary thiocianat had maximal values in the morning and minimal ones in the afternoon; similar behaviour, but less obvious was observed in smoking diabetic patients and in the control group regardless of the smoking habit. LDH activity showed unsignificant diurnal variations in the diabetic patients. In the control group we found a significant decrease of LDH activity in the afternoon. The discussion is about the implication of these salivary parameters in the pathology of oral cavity: gingivitis, periodontitis and caries in diabetic patients.

A total of 180 patients with various haptoglobin (Hp) phenotypes were examined in order to detect specific features of carbohydrate metabolism disorders in pulmonary tuberculosis concomitant with diabetes mellitus. Blood sugar levels, G-6-PDH and LDH, acid-base balance, and 2,3-DPG and HbA1c were evaluated. LDH activity was decreased 1.3-1.7 times in comparison with the norm, G-6-PDH was decreased by 15-45% vs. the norm in 87% patients, acid-base status was imbalanced, HbA1c content was increased 1.5-1.7 times vs. the norm, and 2.3-DPG content was increased 2-3-fold in comparison with the norm in 83% patients. Increased levels of HbA1c and 2,3-DPG in the studied combination of diseases augmented disorders of O2 binding to hemoglobin, which led to hypoxia. The most pronounced shifts in the studied parameters were observed in patients with Hp 2-2 and Hp 1-1. Changes in the studied parameters should be used for the diagnosis of the severity of carbohydrate metabolism disorders in diabetics with pulmonary tuberculosis.

Erythrocytes from diabetic patients exhibit impaired viscoelastic properties when estimated by various methods. We determined erythrocyte filterability through 5-microm pores, in 51 patients with non-insulin-dependent diabetes mellitus, 18 healthy controls, 15 patients with homozygous beta-thalassemia and 15 with beta-thalassemia traits. The filtration measurements were made with a Hemorheometer, which uses the "initial flow rate" principle. To determine the Index of Rigidity (IR) of the red blood cells, we measured the passage time of white blood cell-free erythrocyte suspensions, 8% per volume, through the filter. Diabetic patients had significantly increased IR in comparison to healthy controls and to patients with beta-thalassemia trait, but not at the level found in patients with homozygous beta-thalassemia. In diabetic patients, a strong correlation between IR and the percentage of glycosylated haemoglobin was found (r=0.737, P < 0.0001), and a weaker one with serum unconjugated bilirubin (r=0.363, P=0.0097) and serum total lipids (r=0.321, P=0.0286). Patients with severe retinopathy also had significantly increased IR, in comparison to those with or without mild retinopathy. Anaemic diabetic patients, especially those with the anaemia of chronic disease, also had significantly increased IR in comparison to non-anaemic diabetics. No correlation between IR, MCV, MCH, MCHC, RDW, RBC morphology, serum LDH or the presence of erythrocyte inclusions after incubation with nitrous sodium solution was found. Our findings suggest that glycosylation of skeletal proteins probably contributes significantly to the increased membrane rigidity of diabetic erythrocytes.

Vancomycin hydrochloride (VCM) is widely used for treatment of methicillin-resistant Staphylococcus aureus (MRSA) infections. However, this drug can cause sever adverse reactions, such as red neck syndrome, nephrotoxicity and ototoxicity. Thus, therapeutic drug monitoring (TDM) was bringing into effect for well effectiveness and to prevent side effects. In Kanto Medical Center NTT EC, TDM of VCM has been brought into effect since 1994. The date were accumulated from 200 patients. In this study, the retrospective research was carried out based on 117 cases selected from the above accumulated data, and then several factors such as VCM inducing side effect, a therapeutic effect, and the forecast of pharmacokinetic parameter using laboratory data were examined. Consequently, the high blood concentration trough level, the high value after 1 to 2 hours infusion, and the extension of t1/2 were brought forward as a nephrotoxicity causing factor, and more over each laboratory data (BUN, Cr, GOT, GPT, gamma-GTP, T-BiL, ALP, LDH) was high before infusion of VCM in patients with renal dysfunction. High value T-Bil and lower value TP were brought forward in patients with hepatic dysfunction, and high eosinophils and high blood concentration were brought forward after 1 or 2 hours infusion. In relation to side effects, it was found that the outbreak rate of side effects is high in patients with a complication of hypertension or diabetes. The administration term was considered as a factor which influences the therapeutic effects. The unchanged effect was 10.9 +/- 7.9 days, the improved effect was 14.6 +/- 9.3 days, the remarkably improved effect was 17.7 +/- 14.1 days. As the administration term gets longer, the improvement rate was recognized to be an upward tendency. The difference in significant effects was recognized between unchanged and remarkably unchanged (p < 0.05) effects. As the forecast of pharmacokinetic parameter using the laboratory data, VCMt1/2 showed a significant correlation between Cr and T-BiL, and it was VCMt1/2 = 8.56CR + 2.169T-Bil + 7.1. This result shows that VCMt1/2 can be estimated.

A 58-year-old HIV-negative woman was admitted to our hospital with abdominal distension. She had a 5-year history of hypothyroidism and a 4-year history of diabetes mellitus. Physical examination revealed ascites. There was no lymphadenopathy or splenomegaly. Laboratory examination showed elevated levels of serum LDH and Al-p, polyclonal hypergammaglobulinemia, and was positive for anti-nuclear antibody, several autoantibodies and HCV-RNA. A computed tomographic scan of the abdomen and chest showed massive ascites, but there was no evidence of tumor masses or lymph node enlargement. Cytologic examination of the ascitic fluid revealed numerous abnormal lymphocytes which by flow cytometry demonstrated expression of CD5, CD19, CD20, and CD4. Cytogenetical analysis demonstrated a hyperdiploid karyotype, with numerical abnormalities. Southern blot analysis demonstrated rearranged monoclonal bands in JH and c-mycgenes. Polymerase chain reaction (PCR) analysis failed to detect the genomes of EBV and HHV-8 in the abnormal lymphocytes. A diagnosis of primary effusion lymphoma of B cell lineage was made. Following abdominal paracentesis, the patient remained in complete clinical remission for 7 months and died of an unrelated cause (cerebral bleeding). The present case demonstrated an HIV-, HHV-8-, and EBV-negative, and HCV-positive primary effusion lymphoma of B cell lineage, with a unique clinical course.

Renal proximal tubular epithelial cells (PTEC) are target for LPS during sepsis and renal infections. In the present study, we evaluated whether stimulation of human PTEC by LPS is modulated through the soluble or the membrane form of the LPS receptor CD14. We found that PTEC lacked expression of the membrane form of CD14 and did not release soluble CD14 (sCD14). sCD14 was detected in the urine of normal subjects and it was increased in patients with renal sepsis or with proteinuria. In the presence of sCD14 and LPS binding protein (LBP), PTEC were 10 to 100-fold more sensitive to LPS activation, resulting in cytokine production (IL-6, IL-8 and TNF-alpha) and NO release. We found that sCD14 purified from urine was biologically active on PTEC. Moreover, the presence of sCD14 and LBP was required for cytotoxicity induced by low concentrations of LPS (1-10 ng/ml) in PTEC. Cell death showed the characteristics of both necrosis and apoptosis, as demonstrated by LDH release and by TUNEL and acridine orange staining and caspase-3 activation. Whereas the LPS alone was sufficient to induce necrosis, sCD14 and LBP were required for apoptosis. Our results suggest that sCD14 excreted in urine may participate with endotoxin in the activation and injury of renal proximal tubules. In particular, sCD14 may contribute to the tubulo-interstitial injury in clinical settings characterised by proteinuria and enhanced susceptibility to infections such as in diabetes.

OBJECTIVE: To investigate the correlation between RFCA catheter cumulative energy and autonomic nerve injury. METHODS: Forty-one patients with paroxysmal supraventricular tachycardia were enrolled, Patients were excluded if they had Diabetes, Hypertension, Congestive Heart Failure or other organic heart disease. HRV and biochemical markers were measured before and after the RFCA. RESULTS: Compared with pre-ablation values,there was significantly decrease in post-ablation low frequency (LF) and high frequency (HF). This was noted in both the septal group (AVNRT and septal pathway) and free wall group (free wall accessory pathway).Post-procedure,the sensitivity of cardiac troponin I(cTnI) for myocardial injury detection was 58.3%, AST was 41.7%. This was significantly higher than other markers(CK:4.2%, CK-MB:10.4%, LDH:20.8%). The post-ablation sensitivity of cTnI was 54.2%, 6.3% and 52.1%at 1 hour, 12 hours, and 24 hours respectively. A significant correlation between cumulative energy and delta HF(r=0.688,P=0.01) or delta LF (r=0.462, P<0.05).was noted in free wall group.(delta HF=pre-ablation HF-post-ablation HF/pre-ablation HF x 100%). There was no significant correlation between biochemical markers and either delta HF or delta LF. CONCLUSION: RFCA induced injury on cardiac autonomic nerves related to both cumulative energy and ablation site,but not size of myocardial injury as determined by cTnI measurement. cTnI is an excellent biochemical marker of myocardial injury.

A retrospective survey was performed to establish patient and graft outcome for all 41 patients at our centre receiving sirolimus (SRL) in combination with calcineurin inhibition (CNI) as primary therapy for the 6 years prior to March 2002. Patient mortality [12%; n = 5 (TTP, lymphoma, mucormycosis, and small bowel perforation] was significantly higher at 3 months compared with those not receiving SRL, but not thereafter. 12.8% had delayed graft function and 33% had one or more episodes of rejection in the first 6 months. Mean GFR at 12 months was significantly lower (47.3 mL/min) in the SRL group compared with those not receiving SRL (51.3 mL/min). Twenty-two patients had a 12-month protocol biopsy; CNI toxicity was present in 36%. SRL was associated with significant hyperlipidaemia (serum cholesterol, 5.2 +/- 1.4 at baseline vs 7.3 +/- 1.7 mmol/L at 3 months, P <.001; triglycerides, 2.3 +/- 1.4 at baseline vs 2.7 +/- 1.1 mmol/L at 3 months, P <.05). Mild thrombocytopenia occurred in 23% but was not associated with haemorrhagic events. LDH increased by 62%, remaining elevated out to 2 years post engraftment. Seven patients developed insulin requiring diabetes mellitus, similar to the rate observed in our general transplant population.Thus, in this early experience, SRL in combination with CNI was associated with significant mortality and morbidity including CNI toxicity, presumably a reflection of a heavy burden of immunosuppression. However, 1-year graft survival on SRL was similar to the mean Australia-wide graft survival regardless of immunosuppression. The future use of SRL may center around CNI sparing and avoidance type protocols.
