Cytokine profile in systemic lupus erythematosus,rheumatoid arthritis,and other rheumatic diseases

We investigated serum levels of interleukin-6 (IL-6), interferon-gamma (IFN-), and tumor necrosis factor alpha (TNF) from patients with systemic lupus erythematosus (SLE) and its various clinical manifestations of disease and from patients with rheumatoid arthritis (RA) and other rheumatic diseases. The serum levels of IL-6 and IFN- were highly elevated from patients with SLE associated with lymphadenopathy (LN) or nephrotic syndrome (NS). On the contrary, the serum levels of TNF were elevated from most patients with SLE associated with thrombocytopenia (TP). However, serum levels of TNF were in the normal range from patients with SLE associated with NS, LN, or central nervous system disease. Of interest, patients with SLE associated with humoral immunodeficiency disorder, hypogammaglobulinemia, had highly elevated levels of serum IL-6. The concanavalin A-stimulated mononuclear cells (MNC) of patients with SLE associated with TP secreted highly elevated levels of TNF compared to other patient groups. We suggest that abnormal production of various cytokines in SLE is an intrinsic defect of MNC and the immune system that may be the key element for a variety of clinical manifestations of this disease.

Online health communities,contributions to caregivers and resilience of older adults

The aim of this paper is twofold. Firstly, to investigate the potential benefits of online health communities (OHCs) for informal caregivers by conducting a systematic literature review. Secondly, to identify the relationship between the potential benefits of OHCs and resilience factors of older adults. Performing a thematic analysis, we identified the potential benefits of OHCs for informal caregivers of older adults, including two salient themes: (a) caregivers sharing and receiving social support and (b) self and moral empowerment of caregivers. Then, we uncovered how these potential benefits can support resilience of older adults. Our findings show that sharing and receiving of social support by informal caregivers, and self and moral empowerment of informal caregivers in OHCs, can support four resilience factors among older adults, including self-care, independence, altruism and external connections. This review enables a better understanding of OHCs and Gerontology, and our outcomes also challenge the way healthcare and aged-care service providers view caregivers and older adults. Furthermore, the identified gap and opportunities would provide avenues for further research in OHCs.     

Human leukocyte interferon-α in cream,for the treatment of genital warts in asian women a placebo-controlled,double-blind study

The purpose of this double-blind, placebo-controlled study was to determine and compare the clinical efficacy and tolerance of human leukocyte -interferon (incorporated 2 × 10⁶ IU/g) in hydrophilic cream to cure genital warts. Preselected Asian female patients (n=150) aged 18–40 years (mean 22.5), with the clinical and biopsy-confirmed diagnosis of genital warts (mean 2.64), predominantly flat vaginal condylomas, were randomly allocated to 3 parallel groups. Each patient was given a coded tube containing 80 g placebo/active preparation with a graduated applicator. Patients were instructed to inject 6 g of the either alloted placebo/active cream deep into the vagina thrice a day for 3 consecutive days (group A) or 4 consecutive days (group B) per week, and if not cured the same treatment was extended to 3 more weeks (maximum 4 weeks active treatment). To assess the clinical efficacy patients were examined on a week-to-week basis. A total clearance of warts (biopsy-confirmed) was evaluated as a complete cure. Patients cured during the treatment were spared further treatment and were requested to visit us after 16 weeks for relapse control. As for the remaining patients, empty tubes were collected, and similarly coded replacement tubes were given for further treatment (in total 588 tubes were used). By the end of the treatment 57.2% lesions (227/397) were eliminated in all the groups: 48% patients in group A, 90% patients in group B, and 10% patients in placebo groups taken as completely cured. Of the 150 patients 128 (85.3%) did not complain of any drug-related adverse symptoms. Transitory increase in body temperature (mean 38.4°C), accompanied by headache (14.6%) and generalized itching (6.6%) were the most frequently reported side effects; however, treatment was well tolerated by all the patients, and there were no dropouts. Our findings indicate that clinical efficacy is dose dependent, that is, the results of group B were significantly superior to that of group A (P < 0.05). Of the 49.3% cured patients (74/150) followed up for 6 months (monthly basis) seven had a relapse, and none had reinfection. It is concluded that clinical efficacy of leukocyte interferon-a to cure genital warts is dose dependent. These results further support the view that leukocyte interferon-a incorporated in hydrophilic cream can be considered a reliable, safe, and home-based treatment to cure vulvar and vaginal warts.Abbreviation HPV human papillomavirus     

Cancer-associated retinopathy

Patients with systemic cancer may have a variety of ocular complaints. Most commonly these are metastases or adverse effects of therapy. Paraneoplastic syndromes, like cancer-associated retinopathy, rarely cause ophthalmic symptoms. We describe a patient with a malignant mixed mullerian tumor and cancer-associated retinopathy who had circulating serum antibodies to recoverin and cells positive for recoverin in the tumor. We discuss the typical clinical symptoms as well as the pathophysiology of this uncommon disorder.     

STRUCTURAL CHARACTERISATION OF AN IMMUNOMODULATING POLYSACCHARIDE ISOLATED FROM AQUEOUS EXTRACT OF PLEUROTUS FLORIDA FRUIT-BODIES

The water-soluble glucan was obtained from Pleurotus florida fruit bodies by hot water extraction, ethanol precipitation, DEAE cellulose dialysis and Sephadex G-75 gel filtration. The structural information of the glucan was achieved by chemical (hydrolysis, methylation, periodate oxidation) and spectroscopic (¹H and ¹³C) analyses, indicated a repeating unit built up of (1→6)-linked D-glucose. The following structure has been determined for the repeating unit: →6)-α-D-Glcp-(1→ This fraction exhibited significant macrophage activity through the release of nitric oxide     

Day-case local anaesthetic radiofrequency thermal ablation of benign prostatic hyperplasia: a four-year follow-up

OBJECTIVE: This study reports long-term (median 4 years) clinical effectiveness, safety and patient acceptance of transurethral ablation prostatectomy (TURAPY) for symptomatic benign prostatic enlargement (BPE) using a radiofrequency technique. MATERIAL AND METHODS: 25 men were treated as day-case procedures under local anaesthesia for 1 h. The age range was 55-88 years (mean age 65.5 years) and all were suffering from symptomatic BPE with urinary flow rates of 12 ml/s or less. The treatment was carried out with a computer-based device using a special heating element mounted on a Foley-like catheter for prostatic ablation and the temperatures were monitored continuously in the prostatic region, sphincteric area and rectum for safety purposes. RESULTS: TURAPY was carried out in all patients with temperatures ranging from 70 to 82 degrees C depending on the tolerance of the patient. The post-treatment mortality was nil and only 19 patients complained of mild dysuria, passing of some debris and/or minor bleeding on voiding which settled spontaneously in 2-3 weeks, except in two patients who had proven urinary infection requiring antibiotic therapy. At 4 years the International Prostate Symptom Score (I-PSS) improved from a mean value of 16.0 to 7.2 (p < 0.01) with quality-of-life score falling from 4 to 1.9 (p < 0.05); mean flow rate increased from 8.5 to 11.7 ml/s and mean residual volume decreased from 185.04 to 52.8 ml (p < 0.05). Post-treatment pressure flow studies in 14 patients showed normal pressure voiding in one, with four being in an equivocal range, but the rest were obstructed. Prostate ultrasound scanning before and after treatment in 15 patients showed a mean reduction of volume of 16.7 ml suggesting cavitation of prostate following TURAPY. CONCLUSIONS: TURAPY provides lasting subjective but modest objective benefits in symptomatic BPE patients. It is worthy of consideration in elderly patients, or in those who are unfit for surgery or who do not wish to undergo surgery. It is a safe procedure with little transient morbidity but no mortality.     

Coupling of acceptor-substituted diazo compounds and tertiary thioamides: synthesis of enamino carbonyl compounds and their pharmacological evaluation

This paper describes the synthesis of enamino carbonyl compounds by the copper(i)-catalyzed coupling of acceptor-substituted diazo compounds and tertiary thioamides. We plan to use this method to synthesize indolizidine (−)-237D analogs to find α6-selective antismoking agents. Therefore, we also performed in silico α6-nAchRs binding studies of selected products. Compounds with low root-mean-square deviation values showed more favorable binding free energies. We also report preliminary pharmacokinetic data on indolizidine (−)-237D and found it to have weak activity at CYP3A4. In addition, as enamino carbonyl compounds are also known for antimicrobial properties, we screened previously reported and new enamino carbonyl compounds for antibacterial, antimicrobial, and antifungal properties. Eleven compounds showed significant antimicrobial activities.
