Celecoxib as adjunctive treatment to risperidone in children with autistic disorder: a randomized, double-blind, placebo-controlled trial

Rational

Autism is associated with activation of the inflammatory response system.

Objective

This study aims to assess the efficacy of a cyclooxygenase-2 inhibitor, celecoxib, as adjunctive therapy in the treatment of autism

Methods

In a 10-week randomized double-blind placebo-controlled study, 40 outpatient children with a Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision clinical diagnosis of autism were randomly allocated to celecoxib plus risperidone or placebo plus risperidone. The dose of risperidone and celecoxib were titrated up to 3 and 300 mg/day, respectively. Patients were assessed at baseline and after 2, 4, 6, and 10 weeks of starting medication using the Aberrant Behavior Checklist-Community (ABC-C) Rating Scale. Primary outcome measure was the change in irritability subscale of ABC-C.

Results

Significant time?×?treatment interaction was observed for Irritability (F (1.658, 63.021)?=?13.580, P?<?0.001), Lethargy/Social Withdrawal (F (1.948, 74.032)?=?16.811, P?<?0.001), and Stereotypic Behavior (F(1.742, 66.198)?=?12.104, P?<?0.001), but not for Hyperactivity/Noncompliance (F (2.564, 97.424)?=?1.469, P?=?0.232), and Inappropriate Speech subscales (F (1.607, 61.075)?=?0.173, P?=?0.794). By week 10, patients in the celecoxib group showed significantly greater improvement in the Irritability (P?<?0.001), Lethargy/Social Withdrawal (P?<?0.001), and Stereotypic Behavior (P?<?0.00) but not in Hyperactivity/Noncompliance (P?=?0.202) and Inappropriate Speech (P?=?0.802) subscales than the placebo group. Complete response was achieved by four (20 %) patients in the placebo group and 11 (55 %) patients in the celecoxib group (χ ² (1)?=?5.227, P?=?0.022). Frequency of side effects was similar between the two groups.

Conclusions

Combination of risperidone and celecoxib was superior to risperidone alone in treating irritability, social withdrawal, and stereotypy of children with autism. (Registration, www.irct.ir; IRCT138711091556N2)     

Sensitivity and specificity of a latex agglutination test for detection of calf enterotoxigenic <Emphasis Type="Italic">Escherichia coli</Emphasis> isolates in comparison with PCR

Latex agglutination test is a very fast, accurate, and specific method that is used to diagnose antigens and antibodies which can be carried out in any place without need for any specific devices. In the present study, a single chain (scFv) recombinant monoclonal anti-K99 antibody was used in designing and producing a latex agglutination kit for the detection of enterotoxigenic Escherichia coli of calves colibacillosis. The purpose of this research was to primarily evaluate the sensitivity and specificity of the mentioned latex agglutination kit in the detection of the considered bacteria and to compare it with the results of PCR method. To carry out latex agglutination method, carboxyl latex particles were covered by the recombinant monoclonal antibodies of anti-K99 scFv. Then, these latex particles were mixed with the bacterial suspension purified from the diarrhea samples of the calves on the black cards of kit to observe agglutination. Sensitivity and specificity of the latex agglutination kit in the diagnosis of this colonization factor was evaluated and compared with the results of PCR test. Comparison of the PCR test results with those of the kit indicated that, under the laboratory conditions and on the purified bacteria, sensitivity and specificity levels of the latex agglutination kit were 100 and 96 %, respectively. Primary evaluation showed that the new latex agglutination kit was able to quickly diagnose the K99⁺ bacteria and can be used for the detection of calves colibacillosis.     

Nailfold capillaroscopy changes with disease activity in patients with inflammatory myositis including overlap myositis,pure dermatomyositis,and pure polymyositis

ObjectivesNailfold capillaroscopy (NFC) is useful in the evaluation of connective tissue diseases. There are few capillaroscopy examinations in patients with idiopathic inflammatory myopathies (IIMs) using the 2017 European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) classification. We evaluated the clinical, laboratory, and NFC in patients with IIMs using 2 classifications.Material and methodsIn this cross-sectional study, 150 patients with IIMs were selected based on the EULAR/ACR classification and the Troyanov and Senécal classification. Nailfold capillaroscopy, laboratory tests, clinical manifestations, and disease activity were evaluated.ResultsThe subgroups were as follows: 81 patient with dermatomyositis (DM), 25 with amyopathic dermatomyositis (ADM), 25 with juvenile dermatomyositis (JDM), 19 with polymyositis (PM),53 with pure DM, 11 with pure PM, and 51 with overlap myositis (OM). Eight (42%) patients with PM and 28 (34.5%) patients with DM were categorized as OM. The scleroderma pattern was the dominant capillaroscopy pattern in the DM (72.8%), JDM (72%), ADM (76%), pure DM (75.4%), and OM (78.4%) subgroups, respectively. In the DM, ADM, JDM, and OM subgroups, scleroderma pattern had an association with high skin Visual Analogue Scale (VAS) score (p < 0.05). In OM patients, the association between scleroderma pattern and high global VAS was also detected (p < 0.05).ConclusionsThe scleroderma pattern was the dominant capillaroscopy pattern in all groups except for PM and pure PM. Some of patients with PM could be categorized as OM. In the DM and pure DM subgroups, there was a significant association between global and skin activity and higher NFC score. Adding the NFC to the classification of IIM is probably helpful in more detailed classifications.     

Comparison of the dermatoglyphic characteristics of women with and without breast cancer

Objective

To compare the dermatoglyphic characteristics of women with and without breast cancer.

Study design

Case-control study. One hundred and thirty women = 130 women with histopathologically confirmed breast cancer (case group) were compared with 127 women in the same age group but without breast cancer (control group). Fingerprints of the two groups were compared in terms of whorl, loop and arch patterns.

Results

The loop pattern was most common in both groups [68 women (52.3%) in the case group and 58 women (45.7%) in the control group], followed by the whorl pattern [60 women (46.2%) in the case group and 64 women (50.4%) in the control group]; the difference was not significant (p = 0.337). The number of whorl patterns and the breakdown by classification group did not differ significantly between the two groups. In addition, no significant difference was found in the dermatologlyphic patterns of the women with breast cancer with and without a family history of breast cancer.

Conclusion

No difference was found in the dermatoglyphic characteristics of women with and without breast cancer. As such, this does not appear to be an effective screening method for women at risk for breast cancer.

Prevalence of retinal changes in patients with systemic sclerosis: the association between retinal vascular changes and nailfold capillaroscopic findings

BackgroundSystemic sclerosis (SSc) is a connective tissue disease affecting the skin and multiple organs. Most of the evidence on ocular involvement comes from small studies. We evaluated the retinal vascular changes in patients with SSc and its associations with types, disease duration, skin score, and nailfold capillaroscopy changes.Material and methodsWe evaluated the demographic, clinical and nailfold capillaroscopy data of 52 patients referring to the clinic of scleroderma with SSc according to the 2013 ACR/EULAR SSc criteria. In addition, full ophthalmic examination in 52 patients and fundus photography in 40 patients were done in the ophthalmology clinic.ResultsThere were 52 (49 women and 3 men, 17 diffuse and 35 limited) patients with SSc with mean disease duration of 8 ±5 years and mean age of 40 ±9 years. Retinal changes in the ophthalmologic examination were seen in 30.7% as increased vascular tortuosity. None of the patients had cotton wool spot, hemorrhage or hard exudate. Forty patients underwent fundus photography and 22.5% of them had vascular tortuosity. Only the presence of hemorrhage in the nailfolds was correlated with retinal tortuosity, and the other characteristics of nailfold capillaroscopy did not have any association with retinal changes.ConclusionsRetinal vascular changes were seen in about one third of our patients. There was no correlation between nailfold capillaroscopy, disease duration, type and skin score of SSc patients and retinal vascular changes. These findings suggest that the mechanisms or the quality of changes in the retinal vessels and nailfold vasculature may be different.     

Gemfibrozil,a lipid-lowering drug,improves hepatorenal damages in a mouse model of aging

Gemfibrozil (GFZ) is a medication of the fibrate category with agonistic effects on peroxisome proliferator-activated receptor-α (PPAR-α) and is effective for hypertriglyceridemia and mixed dyslipidemia. This agent also has anti-inflammatory and antioxidant properties. The current study investigated the effects of GFZ on hepatorenal damages in a D-galactose (D-gal)-induced aging model. We used 28 male mice, which were equally and randomly divided into four groups as follows: normal, D-gal (150 mg/kg/day; intraperitoneal [i.p.], for 6 weeks), GFZ (100 mg/kg/day GFZ, orally [p.o.] for 6 weeks), and the combined D-gal + GFZ. Liver and kidney function indices were measured as serum creatinine, blood urine nitrogen, alanine aminotransferase, and aspartate aminotransferase. Oxidative stress in hepatic and renal tissue was evaluated through malondialdehyde, superoxide dismutase, and glutathione peroxidase levels. Finally, the liver and kidney tissues were assessed for histopathological lesions. The results showed that D-gal-induced aging leads to abnormalities in liver and kidney function indices. D-gal also induced significant oxidative stress and histopathological lesions in these organs. GFZ improved function indices and oxidative stress compared to the D-gal-treated animals. Histological evaluations of the liver and kidney also confirmed these results. These data provide evidence for the potential therapeutic of GFZ in clinical practice for mitigating the hepatorenal damages of aging.
