Severe Raynaud's phenomenon from ethosuximide raised concern over possible onset of systemic vasculitis: a case report.

ABSTRACT:

Background

Ethosuximide and other anti-epileptic drugs have been reported to cause idiosyncratic reactions such as lupus-like syndromes, with elevated antinuclear antibody (ANA) levels. Herein, we present a case of a girl who developed a very severe Raynaud's phenomenon reaction and anti-Scl-70 antibodies related to treatment with ethosuximide, due to juvenile absence epilepsy (JAE).

Case presentation

A 12-year-old girl was diagnosed with JAE and treatment with ethosuximide was initiated. Two and a half months later her fingers, digits II-V bilaterally, began to ache and were discolored, alternatingly white, blue, or normal-colored. Two weeks later, her fingers were bluish-black, aching severely, almost continuously. The family sought medical advice. Ethosuximide was halted and due to the severe symptoms, treatment with both prednisolone and intravenous iloprost was commenced. Laboratory tests revealed high ANA levels with anti-Scl-70 pattern and confirmed anti-Scl-70 antibodies. After a few weeks, she started to improve and the symptoms slowly decreased over five months. Anti-Scl-70 was still detectable four months after onset of symptoms, though she was much improved. After eleven months, repeated ANA analyses were completely negative.

Conclusion

Although extremely rare, it is important to recognize that severe Raynaud's phenomenon, threatening peripheral digital circulation, may occur as an idiosyncratic reaction to ethosuximide, raising concern over possible onset of vasculitis.

Project description:BackgroundMany different drugs have been suggested for the symptomatic treatment of primary Raynaud's phenomenon. Apart from calcium channel blockers, which are considered the drugs of choice, the evidence of the effects of alternative pharmacological treatments is limited. This is an update of a review first published in 2008.ObjectivesTo assess the effects of various drugs with vasodilator actions on primary Raynaud's phenomenon.Search methodsFor this update the Cochrane Peripheral Vascular Diseases Group Trials Search Co-ordinator searched the Specialised Register (last searched 14 May 2012), CENTRAL (Issue 4, 2012) and clinical trials databases. We contacted one pharmaceutical company and one trial author for additional information. In addition, the reference lists of relevant studies were searched for additional citations. There were no language restrictions.Selection criteriaRandomised controlled trials evaluating the effects of oral formulations of any drug with vasodilator effects on subjective symptoms in primary Raynaud's phenomenon. Treatment with, or comparison with, calcium channel blockers was not assessed in this review.Data collection and analysisTwo members of the review team independently assessed the trials for inclusion and their quality and extracted the data. Data extraction included adverse events. We contacted trial authors for missing data.Main resultsEight studies involving 290 participants were included. Two trials examined the effects of captopril, the rest were single trials on single drugs. All comparisons were with placebo. The methodological quality of most trials was poor.Enalapril was associated with a small increase in the frequency of attacks per week (difference in means 0.8; 95% CI 0.43 to 1.17). The difference between the intervention groups on a subjective improvement score was non-significant. There was a significant effect of buflomedil on the frequency of attacks per week (weighted mean difference (WMD) -8.8; 95% CI -17.55 to -0.09), but there was no evidence of effect on the severity score. The proportion with fewer attacks was significantly higher on moxisylyte than on placebo (relative risk (RR) 4.33; 95% CI 1.36 to 13.81). For captopril, beraprost, dazoxiben and ketanserin there was no evidence of an effect on the frequency, severity or duration of attacks. Beraprost and moxisylyte gave significantly more adverse effects than placebo.Authors' conclusionsPoor methodological quality, small sample sizes and the limited data available resulted in low precision of the statistical results and limited value of the overall results .The overall results show that there is no evidence for an effect of vasodilator drugs on primary Raynaud's phenomenon.

Project description:ObjectivesSystemic sclerosis (SSc) is a heterogeneous complex autoimmune connective tissue disease with variable presentation as a consequence of multisystem involvement. One of the key features of SSc is Raynaud's phenomenon along with vascular endothelial dysfunction that leads to digital ulcers (DUs). Raynaud's tends to be triggered by decreasing thermal gradient exposure, while stress and smoking also play a role. DUs arising as a consequence of severe Raynaud's and vasculopathy are a major cause of morbidity and disability in SSc. We set out to determine the relationship between smoking, Raynaud's phenomenon, DUs, and skin thickness in our Waikato Systemic Sclerosis cohort.MethodsThe Waikato Systemic Sclerosis (SSc) database was used to extract data. Variables collected included demographics, age of diagnosis, SSc subtypes, age at first non-Raynaud's phenomenon, medications used for treatment of Raynaud's phenomenon or ulcers, and maximal modified Rodnan skin score (mRSS). Raynaud's phenomenon and finger DUs (severity for each over the past week and since diagnosis) and a Scleroderma Health Assessment Questionnaire (SHAQ) visual analog 10 cm scale were collected. The lead rheumatologist completed a physician's assessment of Raynaud's and the disease severity questionnaire.ResultsOf the cohort of 143 patients, 100 patients were eligible to complete the questionnaires. Seventy-five patients returned completed questionnaires. Of these, the majority were female (88%), 52 (69.3%) had limited cutaneous systemic sclerosis (lcSSc), 17 (22.7%) had diffuse cutaneous systemic sclerosis (dcSSc), and 6 (8%) had an overlap syndrome. Thirty-six (48%) had a smoking history (in the time frame of collection of serial data). Mean ± standard deviation (SD) pack-years smoked were 17.11 ± 15.29 years. Thirty-five participants had a history of DUs, with a median of 4 DU (range 1-20). Of 17 patients with dcSSc, 12 (70.6%) had ulcers in comparison with 17 of 52 (32.7%) patients with lcSSc. There was a significant relationship between SSc subtype and the number with ulcers (X2 = 10.1, P = 0.007). There was also a significant relationship between physician severity of Raynaud's and presence of ulcers (t = 6.1, P < 0.001), which was not evident between patients' severity of Raynaud's and presence of ulcers (t = 1.9, P = 0.06). On the SHAQ score, smokers had significantly worse Raynaud's phenomenon over the prior week (t = 3.08, P = 0.03) and were more likely to note DUs over the preceding week, although the latter was not statistically significant (t = 1.95, P = 0.055). There was no association between smoking and skin thickness as measured by mRSS (r = 0.23, P = 0.19).ConclusionOur study demonstrates that smokers have had worse Raynaud's phenomenon over the past week and they were also more likely to note DUs with a trend toward significance but not statistically significant most likely due to our small sample size. Our study also demonstrated that patients with dcSSc had more ulcers in comparison with lcSSc. This study justifies physicians strongly recommending smoking cessation in patients with SSc.
