Inflammatory markers in patients with rheumatoid arthritis

BACKGROUND: Autoimmune diseases such as rheumatoid arthritis (RA) are the consequence of a persistent imbalance between pro- and anti-inflammatory immune mechanisms, leading to chronic inflammation. The objective of this study was to determine whether the high sensitive C-reactive protein (hs-CRP) and cytokines are elevated in RA patients and to investigate the relationship between these markers and disease activity in RA, measured by disease activity score 28 (DAS28). METHODS: We studied 110 RA patients according to American College of Rheumatology revised criteria for RA, and 55 controls matched by age and sex. Serum levels of hs-CRP and cytokines interleukin (IL)-6, IL-10 and tumour necrosis factor- (TNF-) were estimated and correlated with the DAS28. Serum hs-CRP was assayed immunoturbidimetrically and cytokines were analysedby commercially available ELISA kit. RESULTS: We found that RA patients had significantly higher levels of serum hs-CRP (p < 0.001),IL-6 (p < 0.001), TNF- (p < 0.001), and IL-10 (p < 0.01) as compared to healthy controls. hs-CRP, IL-6 and TNF- correlated positively (p < 0.001) and IL-10 correlated negatively (p < 0.01) with DAS28. CONCLUSIONS: These results demonstrate that RA patients have high levels of inflammatory markers, and these levels are correlated with the DAS28. These findings suggest a possible role of these markers in the pathogenesis of RA. Moreover, these biomarkers can be used as markers of disease activity in the diagnosis and treatment of RA

Inflammatory markers in patients with rheumatoid arthritis.

BACKGROUND: Autoimmune diseases such as rheumatoid arthritis (RA) are the consequence of a persistent imbalance between pro- and anti-inflammatory immune mechanisms, leading to chronic inflammation. The objective of this study was to determine whether the high sensitive C-reactive protein (hs-CRP) and cytokines are elevated in RA patients and to investigate the relationship between these markers and disease activity in RA, measured by disease activity score 28 (DAS28). METHODS: We studied 110 RA patients according to American College of Rheumatology revised criteria for RA, and 55 controls matched by age and sex. Serum levels of hs-CRP and cytokines interleukin (IL)-6, IL-10 and tumour necrosis factor-α (TNF-α) were estimated and correlated with the DAS28. Serum hs-CRP was assayed immunoturbidimetrically and cytokines were analysed by commercially available ELISA kit. RESULTS: We found that RA patients had significantly higher levels of serum hs-CRP (p<0.001), IL-6 (p<0.001), TNF-α (p<0.001), and IL-10 (p<0.01) as compared to healthy controls. hs-CRP, IL-6 and TNF-α correlated positively (p<0.001) and IL-10 correlated negatively (p<0.01) with DAS28.

These findings suggest a possible role of these markers in the pathogenesis of RA. Moreover, these biomarkers can be used as markers of disease activity in the diagnosis and treatment of RA.

Hepatitis B, hepatitis C and HIV co-infection at an antiretroviral centre in Delhi.

With an estimated 5.7 million people living with HIV/AIDS, India has the highest HIV/AIDS prevalence in the world, according to UNAIDS. Due to similar routes of transmission, co-infection of HIV with hepatitis B and hepatitis C viruses is a common event with significant clinical implications. The present study was undertaken to highlight the profile of patients of HIV with HBV/HCV co-infection, as literature from India on this topic is sparse. Out of 1953 patients suffering from HIV registered at our centre during the study period, 80 patients were co-infected with HBV/HCV. HBV co-infection was detected in 2.61% of patients and HCV co-infection in 1.69% of subjects. Our study demonstrates low HIV /HCV/HBV co-infection rates in Delhi as compared to most other studies from India, which is partly attributable to low incidence of intravenous drug use and infrequent transfusion-related infections in our study group.

Adolescent behaviour regarding reproductive health.

A cross-sectional household survey was undertaken in rural areas of district Sirmaur, Himachal Pradesh, to assess the knowledge, beliefs and practices of adolescents about reproductive health. Six hundred and forty three unmarried adolescents aged 15-19 years were selected by 30-cluster sampling method from 2400 households. They were interviewed using a semi-structured schedule. Fifty-six per cent were girls. More girls (14%) were illiterate than boys (6%). Most of the boys (88%) and 58% girls knew that a female conceives through sexual intercourse. Seventy seven per cent girls and eighty seven per cent boys were aware of at least one contraceptive method. Majority of the girls (71%) and boys (82.5%) favoured termination of an unwanted pregnancy. About one-fourth respondents considered husband responsible for infertility and for sex of the baby. Boys considered night emission, poor body built and less growth of hair as reproductive health problems, whereas, girls were worried about menstruation and inadequate breast development. Almost 6% boys reported use of a contraceptive method indicating existence of pre-marital sexual activity. Knowledge on reproductive health is low and there is a big gap between actual and desired practices.

Free amino acids in various tissues of a fresh-water teleost, Rasbora daniconius (Ham). I. Qualitative analysis.

Seven different tissues of the fish, Rasbora daniconius are analysed chromatographically for their free amino acid contents. Alanine and Cystine followed by Glycine and Glutamic acid are the most common amino acids found in the tissues. On the basis of sex, no apparent difference in amino acid pattern in various tissues is found. Up to 70% of the amino acids of the pools fall in the range of pH from 4.5-6.5. Thus it appears that the pools have some bearing on the maintenance of the tissue pH.

The testicular cycle of a percoid teleost--Nandus nandus (Ham.).

Small paired testes of Nandus nandus are situated posteriorly in the body cavity. They open posteriorly in a common sperm duct. A urinogenital sinus is present. Each testis consists of a large number of seminiferous tubules extending from the periphery towards the centre. The seminiferous tubules are separated from each other by a layer of interstitial tissue. 6 different stages of spermatogenesis are recognised. On the basis of morphological and histological changes in the testes during different months of the year, the reproduvtice cycle has been divided into post-spawning (October to December), pre-spawning (January to March) and spawning (April to August) periods. The monthly volume of testes is in direct correlation with the monthly changes in water temperature. Statistical observations indicate that the process of spermatogenesis is very active during pre-spawning period. The relative number of spermatozoa is maximum in July (69.89%), suddenly decreases in August (54.28%) and continues to decrease upto October (49.66%) indicating the maximum spawning in July and August.
