Circulating ICAM-1, VCAM-1, E-selectin, P-selectin, and TNFalphaRII in patients with coronary artery disease.

OBJECTIVE: To evaluate the relationship between the serum concentration of TNFalphaRII and some adhesion molecules (including ICAM-1, VCAM-1, P-selectin and E-selectin) and coronary artery stenosis. DESIGN AND SETTING: Observational (cross-sectional) study in a university heart hospital in Tehran, Iran. PATIENTS: 81 patients with angiographically proven coronary artery disease were compared with 75 individuals who had undergone coronary angiography with no significant evidence of stenosis (control subjects). METHODS: Soluble adhesion molecules and TNFalphaRII were determined by enzyme-linked immunosorbent assay technique. sICAM-1 and sP-selectin values were significantly higher in patients with coronary artery disease than in control subjects (146 +/- 38 vs. 132 +/- 48 p < 0.04 and 275 +/- 107 vs. 241 +/- 104 ng/ml p < 0.04 respectively). Multiple logistic regression analysis showed sICAM-1 as an independent discriminating risk factor for coronary artery disease (p < 0.03). Prediction models that incorporated sICAM-1 in addition to other established coronary risk factors were significantly better at predicting risk than the models based on the other risk factors alone. Multiple regression analysis indicated that sP-selectin levels were greater in patients with single-vessel disease than in the respective normal (p < 0.01). CONCLUSIONS: Our findings suggest that sICAM-1 has an association with stable coronary artery disease and the evaluation of this marker may improve the coronary risk assessment in Iranian patients.

A safe, effective, herbal antischistosomal therapy derived from myrrh.

Schistosomiasis is a widespread helminthic disease. Treatment of schistosomiasis is based on chemotherapy with praziquantel, which is the drug of choice. Since resistance to praziquantel has been demonstrated, alternative drugs must be considered. Myrrh is an oleo-gum resin from the stem of the plant Commiphora molmol. This study was carried out on 204 patients with schistosomiasis. The drug was given at a dose of 10 mg/kg of body weight/day for three days, and induced a cure rate of 91.7%. Re-treatment of cases who did not respond with a dose of 10 mg/kg of body weight/day for six days gave a cure rate of 76.5%, increasing the overall cure rate to 98.09%. The drug was well tolerated, and side effects were mild and transient. Twenty cases provided biopsy specimens six months after treatment and none of them showed living ova.

Preliminary study of therapeutic efficacy of a new fasciolicidal drug derived from Commiphora molmol (myrrh).

Myrrh (from the stem of the Commiphora molmol tree) is an oleo gum resin that may prove efficacious for the treatment of fascioliasis. We studied 7 patients who were passing Fasciola eggs in their stools and treated them with myrrh. The drug (a formulation consisting of 8 parts of resin and 3.5 parts of volatile oils, all extracted from myrrh) was given in a dose of 12 mg/kg per day for 6 consecutive days in the morning on an empty stomach. Patients were followed for 3 months. The therapy proved to be effective, with pronounced improvement of the general condition and amelioration of all symptoms and signs. A dramatic drop in the egg count was detected at the end of treatment. Eggs were no longer detectable in the feces 3 weeks after treatment and after a follow-up period of 3 months. High eosinophilic counts, elevated liver enzymes, and Fasciola antibody titers returned to nearly normal. No signs of toxicity or adverse effects were observed. We conclude that the formulation of myrrh is safe, well tolerated, and effective for treating fascioliasis.

Phytosterolemia in children with parenteral nutrition-associated cholestatic liver disease.

BACKGROUND: Lipid emulsions used for parenteral nutrition (PN) contain phytosterols. Our hypothesis was that these phytosterols can accumulate and contribute to cholestatic liver disease and other complications of PN, e.g., thrombocytopenia (which occurs in hereditary phytosterolemia). METHODS: Using gas chromatography-mass spectrometry, plasma concentrations of sterols were measured in 29 children aged 2 months to 9 years receiving PN and in 29 age-matched controls. The children receiving PN fell into two subgroups: 5 with severe PN-associated cholestatic liver disease (bilirubin level, > 100 mumol/L; aspartate aminotransferase [AST] level, > 200 U/L) and 24 with a bilirubin level of < 100 mumol/L and/or AST level of < 200 U/L. RESULTS: The 5 children with severe PN-associated liver disease had plasma concentrations of phytosterols and sitostanol that were as high as those seen in patients with hereditary phytosterolemia (total phytosterols 1.3-1.8 mmol/L). All 5 had intermittent thrombocytopenia. A reduction in intake of lipid emulsion to < 50 mL.kg-1.wk-1 was associated with a decrease in plasma phytosterol concentrations and an improvement in liver function tests and platelet counts in two patients. Children with less severe PN-associated liver disease had lower plasma phytosterol concentrations than the 5 with severe disease. CONCLUSIONS: Children receiving PN who have high plasma phytosterol concentrations also have cholestatic liver disease and thrombocytopenia; phytosterolemia might contribute to the pathogenesis of complications of PN.

Blood superoxide dismutase and plasma malondialdehyde among workers exposed to asbestos.

Blood superoxide dismutase (SOD) and plasma malondialdehyde (MDA) (an indicator of lipid peroxidation [LPO]) were determined in 97 randomly selected asbestos exposed workers (age range: 25-60 years, mean duration of exposures 19.8 +/- 8.3 years) and in 42 healthy male controls. MDA, SOD, and MDA/SOD ratio in asbestos exposed workers were significantly higher than in controls. Among both the controls and exposed workers neither age nor smoking was related to SOD or MDA levels. SOD was significantly positively correlated with MDA among the exposed workers. Such correlation was not observed among the controls. SOD but not MDA was significantly positively correlated with the duration of exposure to asbestos. Mean levels of SOD or MDA in exposed workers with radiographic signs of lung fibrosis or pleural thickening did not differ significantly from those without such signs. The results confirm the possible involvement of LPO and development of anti-oxidant mechanism(s) of prolonged exposure to asbestos in humans. However, SOD seems not to be the essential anti-asbestos-induced LPO. Relation between these factors and lung fibrosis is still unclear.

Antiparietal cell antibodies in gastritis associated with chronic liver diseases.

Thirty patients with gastritis associated with chronic liver disease and ten normal controls were the subject of this study. Pathologically about 18 were diagnosed as chronic atrophic gastritis, 10 as chronic superficial gastritis, 1 as gastric atrophy and 1 as hypertrophic gastritis. Parietal cell antibodies (PCA) were detected (IFA) in 2 cases with no significant relation.

Bacterial flora in hepatic encephalopathy in bilharzial and non-bilharzial patients.

In this work 25 of hepatic encephalopathy cases were studied. 15 cases were due to hepatic schistosomiasis and 9 were due to hepatic schistosomiasis and hepatitis B. virus and one due to hepatic schistosomiasis and drug toxicity of tarter emetic. E. coli was the causative organism in 67% of positive cases, bacteroids were the causative organism in about 33% of positive cases. Urinary tract infection is increased in this study as it was found in 32% of cases and the causative organism were E. coli in about 76% of cases.

The epidemiology of human visceral leishmaniasis in El Agamy (Alexandria Governorate), Egypt: serosurvey and case/control study.

In Alexandria Governorate, Egypt, 27 cases of visceral leishmaniasis (VL) were detected from 1982-1985 through active and passive case detection. Twenty-two were located in El Agamy, a resort town of 50,000 residents located 15 km west of the City of Alexandria. To describe the disease focus, eight areas of 100-200 households in El Agamy were mapped and censused. All individuals were examined clinically, and blood was obtained by finger stick to measure leishmanial antibodies by radioimmune assay. Two case/control studies were carried out in the mapped areas. In one study, case households were more often found near open garbage containers than were control households. In a second case/control study, houses with cases of VL or seropositive individuals were found more likely to face open areas. These results demonstrate that characteristics of houses which could increase exposure to reservoir hosts can be associated with VL or leishmanial seropositivity. This suggests that control programmes should improve garbage disposal and should focus on houses located in peripheral areas of the community.

Parenteral antischistosomal therapy: a potential risk factor for hepatitis B infection.

To study the association between hepatitis B and schistosomiasis, 1,234 Egyptian males, ages 18 to 24, were interviewed, examined, and tested for Schistosoma mansoni infection and HBsAg. Sera from 91 (7.4%) of the study subjects were positive for HBsAg, and S. mansoni was found in the stools of 26.3%. There was no correlation between S. mansoni infection, with or without hepatosplenomegaly, or a history of schistosomiasis, and HBsAg. An association was found between HBsAg positivity and a previous history of parenteral antischistosomal therapy (P less than 0.01). The results of the study indicate that parenteral therapy for schistosomiasis may be a risk factor for hepatitis B antigenemia. Further studies are indicated to determine the importance of parenteral therapy in the transmission of hepatitis B.
