How durable are the effects of cognitive-behavioural therapy‎ in controlling fibromyalgia symptoms? A prospective cohort study

PURPOSE

Cognitive-behavioural therapy (CBT) is widely used for the treatment of fibromyalgia. However, there is no consensus on the durability of its effects on these patients. In this study, we evaluated how durable are the effects of CBT in controlling fibromyalgia symptoms.

METHODS

Forty-eight fibromyalgia patients treated with traditional face-to-face CBT were included. CBT was performed in 20 consecutive group sessions. To evaluate the durability of treatment, the effects of CBT on fibromyalgia symptoms were checked at five time-points: before the CBT, immediately after the CBT, 3 months after the CBT, 6 months after the CBT, and 12 months after the CBT. Outcome measures were the Fibromyalgia impact questionnaire (FIQ) and widespread pain index (WPI).

RESULTS

The mean FIQ score of the patients was 68.3 ± 18.8 before the CBT and 50.5 ± 14.1 1 week after the CBT (p < 0.001). The mean post-CBT FIQ score did not significantly change three and 6 months after the CBT (p = 0.11 and p = 0.09, respectively) while the positive effects of CBT significantly diminished after 12 months (p < 0.001). The mean WPI was 10.4 ± 3.6 before the CBT and 8.6 ± 3.1 1 week after the end of CBT (p < 0.001). The mean WPI of three and 6 months was not statistically different from that immediately after the CBT (p = 0.18 and p = 0.15, respectively), while after 12 months, it significantly worsened (p < 0.001).

CONCLUSION

CBT's beneficial effects for fibromyalgia patients are durable for 6 months. Complementary CBT sessions could be implemented to boost the CBT effect after this period.

Multiple long bone fractures in a man with pycnodysostosis; a case report

Pycnodysostosis is a rare genetic disease that is diagnosed in childhood however in very rare conditions, maybe diagnosed in adulthood. It is presented by dental malformation, short stature and short extremities, multiple fractures with low-pressure forces, and some other manifestations. In this case report, we present a patient with typical pycnodysostosis manifestations including a hard palatine groove, poor hygiene oral situation, dental malformation, and several fractures with a low threshold pressure.

Risk of infection in postmenopausal women with rheumatoid arthritis and osteoporosis taking denosumab and bDMARDS

Background: There is no clear consensus regarding the potential of denosumab for increasing the risk of infection in patients who concurrently receive biologic disease-modifying anti-rheumatic drugs (bDMARDs). In this study, we compared the rate of infection in postmenopausal women with rheumatoid arthritis who received concurrent bDMARDs and denosumab with those who received bDMARDs alone. Methods: In a case-control study, postmenopausal patients with a confirmed diagnosis of rheumatoid arthritis who received concurrent bDMARDs and denosumab for at least one year were identified and included as the case group (n=40). A total of 44 age-matched postmenopausal rheumatoid arthritis women who received bDMARDs alone were included as the control group of the study. Using a chi-squared test, the incidence of bacterial or viral infections was extracted from the patients' profiles and compared between the two study groups. Statistical analyses were performed by SPSS for Windows, version 16 (Chicago, Illinois, USA). A p-value of fewer than 0.05 was regarded as significant. Results: The clinical and demographic characteristics of the patients of the two study groups were not significantly different. In total, four infections were recorded in the present series, two infections in each group. Accordingly, the rate of infection was 4.5% in the bDMARDs alone group and 5% in bDMARDs + denosumab group. This difference was not statistically significant (p=0.655, 95% CI: 0.121-6.742). Three out of four infections were herpes zoster infection. The other one was osteomyelitis of the first metatarsal bone, which occurred in the bDMARDs+denosumab group. None of the infections needed a hospitalization of IV antibiotics. Conclusion: The risk of infection is comparable between postmenopausal osteoporotic women with rheumatoid arthritis who receive bDMARDS alone and those who receive bDMARDS in combination with denosumab.

The Added Value of Trabecular Bone Score in Fracture Risk Assessment of Kidney Transplant Recipients

INTRODUCTION

Trabecular Bone Score (TBS) is an index of bone microarchitecture independent of Bone Mineral Density (BMD). Recently, TBS data has been used to optimize the predictive value of the Fracture Risk Assessment Tool (FRAX). The aim of this study was to evaluate the clinical value of FRAX adjustment with TBS in kidney transplant recipients.

METHODS

Seventy post-transplant Iranian kidney recipients were included in this study. After the evaluation of BMD and TBS, the risk of major osteoporotic fracture (MOF) and hip fracture (HF) was assessed once with and once without TBS adjustment. The proportion of patients who needed a therapeutic intervention was compared before and after TBS adjustment. The association between TBS and BMD data was also evaluated.

RESULTS

The mean age of the patients was 54 ± 8.8 years (range: 40 to 77). The mean TBS of the patients was 1.30 ± 0.12. In multivariate analysis, the TBS was significantly associated with the age (P < .05) and dialysis period (P < .05). A strong correlation was found between the spine BMD and TBS data (r = 0.612, P < .001). A significant correlation was found between the MOF and HF of the patients before and after adjustment for TBS. The proportion of patients needed a therapeutic intervention significantly increased from 17.1% to 25.7% after TBS adjustment of FRAX.

CONCLUSION

Adjustment of FRAX with TBS will reclassify the treatment decision in a considerable number of kidney transplant recipients. This clinical value warrants the adjustment of FRAX data with TBS in future workouts.

The effect of cognitive behavioral therapy on the circulating proinflammatory cytokines of fibromyalgia patients: A pilot controlled clinical trial

OBJECTIVES

There is no consensus over the effect size of cognitive behavioral therapy (CBT) in the treatment of fibromyalgia (FM). This study aims to evaluate the effect of CBT on FM patients, through assessing circulating proinflammatory cytokines.

METHODS

A controlled, single-blind, parallel clinical trial was performed with 21 FM patients in each group. Sixteen FM patients in the intervention group (CBT) and 17 FM patients in the control group (waiting-list) completed the study. For the intervention group, traditional face-to-face CBT was performed for groups of 10 and 11 patients in 20 sessions. Fibromyalgia Impact Questionnaire (FIQ), widespread pain index (WPI), circulating IL-6, IL-8, and TNF-α level were evaluated before and after the intervention using enzyme-linked immunosorbent assay. Intention-to-treat analysis was performed as the primary analysis.

RESULTS

The average changes of factors examined were as follows: FIQ score -0.61 ± 5.5 in the waiting-list group and 10.2 ± 14.9 in the CBT group (p = 0.012); WPI -0.33 ± 1.1 in the waiting-list group and 2.4 ± 3.1 in the CBT group (p = 0.002); serum IL-6 level -0.05 ± 0.86 pg/ml in the waiting-list group and 1.5 ± 2.4 pg/ml in the CBT group (p = 0.002); serum IL-8 level - 0.55 ± 0.2.5 pg/ml in the waiting-list group and 5 ± 5.9 pg/ml in the CBT group (p = 0.002); serum TNF-α level 0.67 ± 1.8 pg/ml in the waiting-list group and 0.7 ± 1.6 pg/ml in the CBT group (p = 0.89).

CONCLUSION

Reductions in proinflammatory cytokines after CBT compared with a waiting-list control group confirm the potential value of these biomarkers as surrogate outcome measures in FM.

Differentiation of Cocaine-Induced Midline Destructive Lesions from ANCA-Associated Vasculitis

INTRODUCTION

Cocaine-induced midline destructive lesions (CIMDL) are complications of regular nasal cocaine inhalation. CIMDL can mimic systemic diseases with positive anti-neutrophil cytoplasmic antibodies (ANCA), such as granulomatosis with polyangiitis (GPA).

CASE REPORT

In this article, we describe the case of a young woman who presented with nasal perforation induced by cocaine, along with positive perinuclear ANCA test (proteinase 3 antigen), misdiagnosed as limited GPA. The patient was treated with immunosuppressive therapy, which partially improved her symptoms. Admittance of cocaine use aided in the diagnosis of CIMDL. This patient was advised to stop cocaine use. Three-month follow-up revealed no further complications.

CONCLUSION

Considering the seropositivity of ANCA in both CIMDL and GPA, early diagnosis of CIMDL and its differentiation from GPA is crucial, and clinicians play an important role in this regard. Lack of distinct histologic characteristics of vasculitis or unresponsiveness to standard therapeutic regimens may favor the diagnosis of CIMDL syndrome. It is crucial to recognize that these conditions may have similar presentations, so that undesired and potentially toxic treatments can be prevented.

Seropositivity of Rheumatoid Arthritis Specific Tests in a Patient With Nephrotic Syndrome: Successful Treatment With Rituximab

Presentation of rheumatoid arthritis (RA) with renal complications is very rare without articular symptoms. We here report a case of a 23-year-old woman, presenting with the edema of the extremities, no relevant previous medical history, and the features of acute tubular injury in her percutaneous kidney biopsy. Following the incidental notification of a positive rheumatoid factor test, other immunologic tests including anticyclic citrullinated peptide and antimutated citrullinated vimentin were performed, the positive results of which favored the diagnosis of RA. Administration of rituximab led to the complete remission of the disease. Six weeks later, along with steroid dose reduction, the symptoms of arthralgia was observed, which was managed with methotrexate. Nephrotic syndrome could be rarely the first manifestation of RA, and screening of specific RA autoantibodies might be considered as part of diagnostic evaluations in nephrotic syndrome workup.

Posterior reversible encephalopathy syndrome in a patient with mixed connective tissue disease: a case report

Background

Posterior reversible encephalopathy is a syndrome highly associated with hypertension and cytotoxic therapy. The syndrome typically presents with headache, visual abnormality, seizures and characteristic vasogenic edema on magnetic resonance imaging. The entity warrants a prompt diagnosis to avoid deteriorating consequences.

Case presentation

In this report, we describe a 15-year-old Iranian boy who was diagnosed with mixed connective tissue disease, and cyclophosphamide pulse therapy was administered. Three days after the second pulse of cyclophosphamide, when he was receiving prednisolone and hydroxycholoroquine, our patient developed generalized tonic-clonic seizures. Magnetic resonance imaging findings showed high signal intensities in the posterior areas of his brain. After 8 days, the brain magnetic resonance imaging abnormalities were resolved following the control of his blood pressure and antiepileptic treatment. These observations have been indicative of posterior reversible encephalopathy syndrome. Nevertheless, our patient developed uncontrollable respiratory distress and eventually died.

Conclusions

To the best of our knowledge, this case is the first report of posterior reversible encephalopathy syndrome in a patient with mixed connective tissue disease. As the patient developed posterior reversible encephalopathy syndrome 3 days after cyclophosphamide pulse therapy to reduce the disease activity, it is hard to accurately determine whether posterior reversible encephalopathy syndrome in this case is a complication of cyclophosphamide or a condition that resulted from the mixed connective tissue disease flare-up.

Longstanding hypoparathyroidism in a fifty-two-year-old woman misdiagnosed as spondyloarthropathy

Introduction:

Hypoparathyroidism might cause various musculoskeletal findings, resembling Spondyloarthropathies.

Case Presentation:

We described a 52-year-old woman, diagnosed as a case of undifferentiated spondyloarthropathy for ten years, who was unresponsive to classic anti-inflammatory therapies. She developed anterior ischemic optic neuropathy and had elevated muscle enzymes during the course of disease. On a routine checkup, marked hypocalcemia and suppressed parathyroid hormone levels were found. Calcium and calcitriol therapy led to clinical and laboratory improvement.

Conclusions:

This case emphasizes the importance of recognizing rheumatic manifestations of hypoparathyroidism to preclude unnecessary treatments. Serum calcium should be included in the diagnostic workup of these patients.

Hypovitaminosis d: are medical students at risk?

BACKGROUND

Vitamin D deficiency is a pandemic problem mostly diagnosed in elderly. Few studies are available exclusively done on the topic among young adults. Specific professions such as medical students may have higher risk for developing hypovitaminosis D. We aimed to assess the vitamin D status in medical students of Iran University of Medical Sciences; and to define a cut-off point for 25-hydroxyvitamin-D (25(OH)D) level based on secondary hyperparathyroidism.

METHODS

This was a cross-sectional study on 100 medical students conducted during October 2012. Serum 25(OH)D, intact parathyroid hormone (iPTH), and calcium were measured. Age, sex, body mass index, daily dietary fish and egg consumption, sun exposure, and sunscreen usage were recorded. The association between serum 25(OH)D and iPTH was assessed. Receiver operating characteristics curve analysis was performed.

RESULTS

25-hydroxyvitamin-D level was <30 ng/ml in 99% of all participants, and <20 ng/ml in 77%. Mean serum 25(OH)D level was 16.8 ± 4.7 ng/ml. iPTH level in the group with 25(OH)D level of <10 ng/ml was significantly higher than in those with serum 25(OH)D level of 10 to <20 ng/ml and 20 to <30 ng/ml (109 ± 47 pg/ml, 47 ± 27 pg/ml and 46 ± 19 pg/ml, respectively; P = 0.0001). There was a significant linear inverse correlation between serum iPTH and 25(OH)D (r = -0.36, P = 0.0001). 25(OH)D level of 15.4 ng/ml was determined as the optimal cut-off point in detecting possible secondary hyperparathyroidism.

CONCLUSIONS

To improve the community vitamin D status, in addition to population-based food fortification programs, educational programs seem essential; not only for general population, but also for the more educated groups.

The effect of quercetin on plasma oxidative status, C-reactive protein and blood pressure in women with rheumatoid arthritis

BACKGROUND

Considering the increased production of free radicals and inflammatory factors in rheumatoid arthritis (RA) and the effects of bioflavonoid quercetin on reducing oxidative stress, inflammation and blood pressure, the present study examined the effects of bioflavonoid quercetin on total antioxidant capacity (TAC) of plasma, lipid peroxidation and blood pressure in women with RA.

METHODS

The current study was a randomized double-blind clinical trial in which 51 women with RA aged 19-70 years, were participated. Patients were assigned into quercetin (500 mg/day) or placebo groups for 8 weeks. Dietary intake was recorded using 24-h dietary recall questionnaire and the physical activity was assessed through an international short questionnaire of physical activity at the beginning and end of the study. Plasma TAC and malondialdehyde (MDA) using colorimetric method, oxidized low density lipoprotein (ox-LDL) and high sensitivity C-reactive protein (hs-CRP) using enzyme-linked immunosorbent assay method and also blood pressure were measured at the beginning and end of intervention.

RESULTS

After 8 weeks there were no significant differences in TAC of plasma, ox-LDL, MDA, hs-CRP, systolic and diastolic blood pressure between quercetin and placebo groups and in each group comparing before and after.

CONCLUSIONS

In this study, quercetin had no effect on oxidative and inflammatory status of plasma and blood pressure in patients with RA. Further studies are needed to ensure the effect of quercetin on oxidative stress and inflammation in human.

Treatment of hypovitaminosis D with pharmacologic doses of cholecalciferol, oral vs intramuscular; an open labeled RCT

OBJECTIVE

Vitamin D deficiency is a worldwide health problem. Usual supplements are inadequate for prevention of hypovitaminosis D, and much higher doses are needed for its treatment. This study was designed to compare the efficacy and practicality of high-dose intramuscular and oral cholecalciferol in treatment of hypovitaminosis D and to evaluate durability of the effect of each remedy.

DESIGN

Ninety-two patients with hypovitaminosis D [serum 25(OH) D level < 75 nmol/l] were enrolled in a randomised clinical trial. Participants were randomly assigned to receive 300 000 IU cholecalciferol, either intramuscularly as a single injection or orally in six divided doses during 3 months period. Serum 25(OH) D level was measured at baseline and at 3 and 6 months.

RESULTS

Both treatment regimens significantly increased the serum 25(OH)D level. Delta change in serum 25(OH) D level from baseline (presented as mean ± SEM) at month 3 was significantly higher in oral than injection group (90 ± 11·2 and 58·8 ± 8·9 nmol/l, respectively, P = 0·03); but was similar at 6th month intervention (52·1 ± 7·6 and 62·2 ± 6·7 nmol/l, respectively, P = 0·32). There was a marginally significant trend in favour of oral group in the proportion of cases attained vitamin D adequacy at 6th month (P = 0·06); but still 15% of all patients remained at < 50 nmol/l.

CONCLUSION

Both regimens were considerably effective, safe and practical in treating hypovitaminosis D. Although we revealed superiority of oral route, at least at early short time, the way of treatment may depend on the patient's choice, compliance and availability of various forms of the drug in any regions.

Coil embolization of persistent sciatic artery pseudoaneurysm presenting as blue toe syndrome, a rare case

In this report, a case of blue toe syndrome related to persistent sciatic artery pseudoaneurysm in a 63-year-old woman, which was diagnosed by selective angiography, is presented. The pseudoaneurysm was successfully treated with coil embolization with good clinical results. A persistent sciatic artery is a rare embryological anomaly that occurs when the sciatic artery fails to regress during fetal development. Therefore, thromboembolisms from persistent sciatic artery aneurysm are rare.
