Functional status and health-related quality of life of elderly osteoarthritic patients treated with celecoxib

BACKGROUND: This study evaluates the impact of celecoxib on functional status, health-related quality of life (HRQOL), and safety of elderly patients (> or =70 years) with osteoarthritis (OA) of the knee and/or hip. METHODS: Data were pooled from three prospective, randomized, multicenter, double-blind, parallel group trials, each having a 12-week treatment period. Multicenter studies were conducted in the United States and Canada. Data for patients diagnosed with active OA of the knee and/or hip in a flare state who were 70 years of age and older were included in the comparison of therapeutic doses of celecoxib or naproxen versus placebo (N = 768). Elderly patients from each of the three trials who were randomly assigned to groups treated with a placebo. 200 mg/day of celecoxib, 400 mg/ day of celecoxib, or 1000 mg/day of naproxen were included in this analysis. The Western Ontario and McMaster Universities Osteoarthritis Index was used to measure functional status. The Short Form-36 was used as a general measure of HRQOL. Safety was assessed according to the incidence and type of adverse reactions as reported by the patients and the rate of withdrawal due to adverse events. RESULTS: At the end of the treatment period, patients in the celecoxib groups had significant improvement in both functional status and HRQOL in comparison with the placebo group. The effects of total daily doses of 200 mg of celecoxib, 400 mg of celecoxib, and 1000 mg of naproxen on functioning and HRQOL were not found to be significantly different from each other. The incidence of serious adverse events and withdrawal from the studies due to adverse events were similar in the celecoxib groups as they were in the placebo group. Overall, the naproxen group reported a significantly higher incidence of gastrointestinal adverse events than did the placebo and the 200-mg-daily celecoxib groups. CONCLUSIONS: This study showed that celecoxib and naproxen significantly improved functional status and HRQOL in elderly patients compared with those treated with a placebo. Celecoxib-treated patients were also found to experience safety and tolerability similar to that of the placebo-treated patients.     

Giant-cell arteritis in the southern United States. An 11-year retrospective study from the Texas Gulf Coast

Giant-cell arteritis (GCA) and polymyalgia rheumatica are systemic disorders that reportedly affect primarily white women older than age 50 years. We conducted an 11-year chart review to determine the relative occurrence and pattern of demographic involvement of GCA in the Gulf Coast region of the United States. Of 101,239 computer-coded entries for individual patients aged 40 years or older, 60 charts listed GCA as a differential diagnosis. Twenty-seven patients had temporal GCA; 21 temporal artery biopsy specimens were identified. Two patients had associated systemic GCA (one with aortitis). A striking finding was that 13 of the 27 patients were black women (about 50% of the entire study population). The group with GCA and polymyalgia rheumatica (17 patients) had a significantly higher mean erythrocyte sedimentation rate than the group with "pure" GCA. Jaw claudication and blindness were rare. We concluded that temporal GCA seems relatively uncommon in the Gulf Coast region and in the southern United States as a whole. Furthermore, GCA seems rare in Hispanics (only one patient identified). Nonetheless, this is the first report to document a proportionally high occurrence of GCA in black patients in this part of the country.     

The effect of glucosamine and/or chondroitin sulfate on the progression of knee osteoarthritis: a report from the glucosamine/chondroitin arthritis intervention trial

OBJECTIVE: Osteoarthritis (OA) of the knee causes significant morbidity and current medical treatment is limited to symptom relief, while therapies able to slow structural damage remain elusive. This study was undertaken to evaluate the effect of glucosamine and chondroitin sulfate (CS), alone or in combination, as well as celecoxib and placebo on progressive loss of joint space width (JSW) in patients with knee OA. METHODS: A 24-month, double-blind, placebo-controlled study, conducted at 9 sites in the United States as part of the Glucosamine/Chondroitin Arthritis Intervention Trial (GAIT), enrolled 572 patients with knee OA who satisfied radiographic criteria (Kellgren/Lawrence [K/L] grade 2 or grade 3 changes and JSW of at least 2 mm at baseline). Patients with primarily lateral compartment narrowing at any time point were excluded. Patients who had been randomized to 1 of the 5 groups in the GAIT continued to receive glucosamine 500 mg 3 times daily, CS 400 mg 3 times daily, the combination of glucosamine and CS, celecoxib 200 mg daily, or placebo over 24 months. The minimum medial tibiofemoral JSW was measured at baseline, 12 months, and 24 months. The primary outcome measure was the mean change in JSW from baseline. RESULTS: The mean JSW loss at 2 years in knees with OA in the placebo group, adjusted for design and clinical factors, was 0.166 mm. No statistically significant difference in mean JSW loss was observed in any treatment group compared with the placebo group. Treatment effects on K/L grade 2 knees, but not on K/L grade 3 knees, showed a trend toward improvement relative to the placebo group. The power of the study was diminished by the limited sample size, variance of JSW measurement, and a smaller than expected loss in JSW. CONCLUSION: At 2 years, no treatment achieved a predefined threshold of clinically important difference in JSW loss as compared with placebo. However, knees with K/L grade 2 radiographic OA appeared to have the greatest potential for modification by these treatments.     

Cross-sex transmission of infection and increased mortality due to measles

In an urban and a rural area of Guinea-Bissau, the incidence of and mortality due to measles were followed over four years. Significantly higher case-fatality ratios among secondary cases occurred when infection was transmitted across sexes than within the same sex. The case-fatality ratio was highest for girls infected by boys and lowest for girls infected by girls. Published reports of cases of fatal measles indicate a similar tendency. Apparently, no general background factor or difference in social interaction between children can explain this variation in severity of infection. It is therefore hypothesized that cross-sex transmission of measles virus produces infections of greater severity. These observations may suggest that measles virus incorporates host-specific cellular characteristics that interfere with the immune responses of persons infected by a member of the opposite sex.     

Isolation of Mycoplasma pneumoniae from synovial fluid samples in a patient with pneumonia and polyarthritis

A patient with a long history of arthritis developed pneumonia. Two weeks into her hospital course, the patient developed effusions in her knee and wrist that yielded cultures positive for Mycoplasma pneumoniae. To our knowledge, this is the third reported case of M pneumoniae isolation from a joint and the first report of isolation of M pneumoniae from two joints in a patient without hypogammaglobulinemia. The evidence suggests that in individuals with atypical pneumonia and joint effusions, M pneumoniae should be considered as a source of infection.

Thymus size and head circumference at birth and the development of allergic diseases

BACKGROUND: The positive association between a large head circumference at birth and total serum IgE levels has been suggested to be due to negative associations between head circumference at birth and thymus development and between thymus development and total serum IgE levels. OBJECTIVES: To examine the associations between head circumference and thymus size at birth and the development of allergic disease. METHODS: The size of the thymus was assessed by sonography during the first week of life in 149 healthy term infants. Information on birth characteristics and mode of delivery was collected at delivery. The presence of allergic disease was assessed 5 years later by mailed questionnaires, which were returned by 85% of the eligible families. RESULTS: At birth, head circumference was positively associated with thymus size (P < 0.001). In all, 27 (23%) of the children had developed at least one allergic disease. Multivariate analysis revealed that both parental allergy (Prevalence Ratio and 95% CI) = 3.18 (1.49-6.78)) and caesarean delivery (2.62 (1.48-4.64)) were independently correlated with allergic disease, whereas thymus size was not. CONCLUSIONS: Our study does not support that a large head circumference is associated with a small thymus size, nor that a small thymus size is associated with allergic disease. Whether thymus size at birth is related to total serum IgE levels still remains to be elucidated.     

Procollagen type III aminoterminal peptide in serum in idiopathic myelofibrosis and allied conditions: relation to disease activity and effect of chemotherapy

The serum concentration of the aminoterminal propeptide of type III procollagen (PIIINP) was measured serially in patients with idiopathic myelofibrosis and other myeloproliferative syndromes. Two different assays were applied, the RIA-gnost assay (Hoechst, Frankfurt, FRG) and a new equilibrium RIA for the N-terminal propeptide of human type III procollagen (Farmos Diagnostica, Oulu, Finland). A positive correlation was found between the results obtained by the two RIA's (rho = 0.90, P less than 0.001). The highest propeptide levels were recorded in patients with idiopathic myelofibrosis, particularly in those with active disease. Elevated serum PIIINP levels decreased during treatment with various cytotoxic drugs, including intensive chemotherapy. By contrast, serum PIIINP was unchanged or increased in patients undergoing interferon alpha-2b therapy. Gel filtration of sera on Sephacryl S-300 column (Pharmacia, Sweden) showed that smaller PIIINP related peptides dominated in healthy subjects and in osteomyelosclerosis with stable disease. Conversely, the relative proportion of intact propeptide increased in accelerating disease stages and acute myelofibrosis. In conclusion, the present study implicates serum PIIINP as a useful indicator of disease activity in idiopathic myelofibrosis. The propeptide also appears to be a sensitive sero-marker of chemotherapy effect on fibrogenesis related to clonal myeloproliferation. Finally, the propeptide is suggested as an early predictor of relapse during cytotoxic therapy.
