Common Neurologic Features of Lyme Disease That May Present to a Rheumatologist.

Lyme disease, caused by Borrelia burgdorferi (Bb) infection, has a broad spectrum of clinical manifestations and severity. Patients with possible Lyme disease may seek out or be referred to rheumatologists. Today, the most common reason to engage a rheumatologist is due to complaints of arthralgia. After skin, neurologic manifestations of Lyme disease are now among the most common. Therefore, it is important for rheumatologists to be aware of clues that suggest neurologic Lyme disease and prompt help from a neurologist experienced with Lyme disease.

Is nasal saline irrigation all it is cracked up to be?

OBJECTIVE: This review examines the literature regarding nasal saline irrigation in the management of sinonasal disease. We explore the various properties of nasal irrigation solutions and their effects on nasal symptoms. DATA SOURCES: English-language studies identified from MEDLINE and the Cochrane Central Register of Controlled Trials through December 2011. STUDY SELECTIONS: Randomized, controlled trials (RCTs), prospective controlled and comparative studies, and observational studies reporting on the indications, efficacy, and safety of nasal saline irrigation. RESULTS: Nasal saline irrigation has often been used as both a solo and an adjunctive treatment in sinonasal diseases, including allergic rhinitis and chronic rhinosinusitis. Nasal saline irrigation has contributed to a reduction of inflammation as well as relief of nasal symptoms. Identifying the optimal technique is hampered by the fact that studies have employed various delivery devices and saline compositions, which subsequently have demonstrated different effects on mucus clearance, ciliary beat activity, and inflammatory mediators. CONCLUSION: Overall, the data appear to demonstrate some small clinical benefit to nasal saline irrigation. Nasal saline irrigation is well tolerated, with minimal side effects. Further definitive studies are needed to optimize efficacy.

COVID-19 Vaccination as a Potential Trigger for New-Onset Systemic Lupus Erythematosus.

Immune hyperactivation has been linked to various vaccines. We present a potential association of new-onset systemic lupus erythematosus (SLE) post-COVID-19 immunization. The patient is a 54-year-old male admitted for evaluation of flu-like symptoms two weeks after receiving the second dose of the COVID-19 vaccine. Physical examination revealed high-grade fever, diffuse bilateral non-tender cervical lymphadenopathy, and erythematous maculopapular palpable purpuric lesions on bilateral feet. Laboratory evaluation showed a significant hypocomplementemia (C3 < 11 mg/dL, C4 < 3 mg/dL, and CH50 < 10 U/mL), high titer antinuclear antibody, anti-dsDNA antibodies, anti-Sjogren's syndrome-related antigen A antibodies, anti-Sjogren's syndrome-related antigen B antibodies, anti-Smith antibodies, anti-ribonucleoprotein antibodies, anti-histone antibodies with a negative malignancy, and infection workup. The patient was treated with a high dose of steroids with a positive response. This case highlights the possibility of SLE, a rare adverse event following COVID-19 vaccination.

Updates in diagnostics, treatments, and correlations between oral and ocular manifestations of Sjogren's syndrome.

Sjogren's syndrome (SS) is characterized as an autoimmune disorder targeting secretory glands, including the lacrimal and salivary glands, causing dry eye and dry mouth predominantly in women over the age of 40. In this review, we summarize recent advancements in SS diagnostics, treatments, and our understanding of correlations between oral and ocular manifestations of SS. Google Scholar and PubMed databases were utilized to search peer-reviewed papers since 2016 on SS diagnosis, treatment, and correlations between oral and ocular manifestations. For diagnostics, we discuss the updated SS classification criteria by the American College of Rheumatology/European League Against Rheumatism (ACR/EULAR), new biomarkers, and compare studies of current diagnostic methods with alternative technologies. For treatments, we discuss topical, systemic, and surgical treatment developments in the management of oral and ocular symptoms of SS as there is still no cure for the disorder. Finally, we report studies that directly suggest correlations between the ocular surface disease and oral disease in SS, as well as shared abnormalities in the microbiome and cytokine expression that may be correlated. We conclude by stating limitations to our review as well as paths moving forward. Elucidating correlations between oral and ocular manifestations may be the key to furthering our understanding of SS pathogenesis as well as defining new standards for diagnosis and treatment.

A Case of Severe Refractory Pemphigus Vulgaris in a Patient With Stable Esophageal Malignancy.

Pemphigus is a broad term that is used to describe a group of bullous autoimmune diseases affecting the skin and mucous membranes; the pathogenesis involves autoantibodies directed against various cell junction desmosomal proteins. In patients with a history of malignancy who present with bullous lesions, the differential diagnosis may include, but is not limited to, paraneoplastic pemphigus (PNP) and pemphigus vulgaris (PV) secondary to a primary autoimmune process, or induced by chemotherapy or radiation therapy. In this report, we present a case of refractory PV in a patient with stable esophageal cancer, five years after undergoing radiation therapy. He was poorly responsive to corticosteroids and intravenous immunoglobulin (IVIG). PNP or PV in a patient with stable esophageal malignancy has not been previously reported. PNP and PV can have overlapping autoantigens [desmoglein types 1 and 3 (DSG1 and DSG3)] as well as similar presentations. Thus, distinguishing between the two may be challenging in a patient with a history of cancer. More research must be done to determine if PNP can be seen in a patient with stable esophageal malignancy and, similarly, if PV can be precipitated by stable esophageal malignancy. Such research would aid in determining whether or not similar presentations are more severe or refractory to standard treatment regimens, thereby contributing to improve treatment strategies.

Arthritis and Diagnostics in Lyme Disease.

The diagnosis of Lyme disease, caused by Borrelia burgdorferi, is clinical but frequently supported by laboratory tests. Lyme arthritis is now less frequently seen than at the time of its discovery. However, it still occurs, and it is important to recognize this, the differential diagnoses, and how laboratory tests can be useful and their limitations. The most frequently used diagnostic tests are antibody based. However, antibody testing still suffers from many drawbacks and is only an indirect measure of exposure. In contrast, evolving direct diagnostic methods can indicate active infection.

Stevens Johnson Syndrome in a Patient with Giant Cell Arteritis During Short Term Tocilizumab Therapy.

This case report represents a rare life-threatening hypersensitivity reaction of tocilizumab drug when it is used to treat giant cell arteritis. An elderly female with history of bilateral giant cell arteritis with anterior ischemic optic neuropathy of the right eye was started on tocilizumab after developing glucocorticoid-related complications. She received one month of the tocilizumab therapy along with the prednisone taper. The patient initially developed sinus and mucosal edema, presented as drooling with mild tongue and lip swelling. It eventually progressed into development of new onset of erythematous macules and flaccid bullae which was biopsy-confirmed Stevens Johnson syndrome. Tocilizumab drug was immediately discontinued and she was treated with supportive care. The goal of this report is to present the first detailed case of presumed tocilizumab-induced Steven Johnson syndrome which emphasizes the importance of post-marketing surveillance and collection of data on adverse events of this drug.

Controversies regarding long-acting ß2-agonists.

PURPOSE OF REVIEW: This review examines the literature regarding the efficacy and safety of long-acting ß2-agonists as add-on therapy to inhaled corticosteroids. RECENT FINDINGS: The Global Initiative for Asthma (GINA) 2009 guidelines and the National Heart, Lung, and Blood Institute (NHLBI) 2007 asthma guidelines recommend adding long-acting ß2-agonists to patients inadequately controlled on inhaled corticosteroids. These recommendations must be balanced against published data which demonstrate a signal of increased morbidity and mortality with use of long-acting ß2-agonists. These conflicting data raise the question of whether or not there may be genotypic or phenotypic discriminators leading to disparate responses to long-acting ß2-agonists. SUMMARY: The combination of long-acting ß2-agonists and inhaled corticosteroids demonstrates improvement in asthma control and exacerbation rates; however, long-acting ß2-agonists are not recommended for use as monotherapy or without optimization of inhaled corticosteroid dose. Although the majority of asthmatic patients appear to benefit from the addition of long-acting ß2-agonists, there are concerns that a small proportion of patients, including steroid-naïve patients and African Americans, may not obtain such benefits. Thus far, studies have not clearly demonstrated genotypic or phenotypic differences explaining the variability in response.

Impact of intracoronary cell therapy on left ventricular function in the setting of acute myocardial infarction: a collaborative systematic review and meta-analysis of controlled clinical trials.

OBJECTIVES: We aimed to perform a meta-analysis of clinical trials on intracoronary cell therapy after acute myocardial infarction (AMI). BACKGROUND: Intracoronary cell therapy continues to be evaluated in the setting of AMI with variable impact on left ventricular ejection fraction (LVEF). METHODS: We searched the CENTRAL, mRCT, and PubMed databases for controlled trials reporting on intracoronary cell therapy performed in patients with a recent AMI (< or =14 days), revascularized percutaneously, with follow-up of > or =3 months. The primary end point was change in LVEF, and secondary end points were changes in infarct size, cardiac dimensions, and dichotomous clinical outcomes. RESULTS: Ten studies were retrieved (698 patients, median follow-up 6 months), and pooling was performed with random effect. Subjects that received intracoronary cell therapy had a significant improvement in LVEF (3.0% increase [95% confidence interval (CI) 1.9 to 4.1]; p < 0.001), as well as a reduction in infarct size (-5.6% [95% CI -8.7 to -2.5]; p < 0.001) and end-systolic volume (-7.4 ml [95% CI -12.2 to -2.7]; p = 0.002), and a trend toward reduced end-diastolic volume (-4.6 ml [95% CI -10.4 to 1.1]; p = 0.11). Intracoronary cell therapy was also associated with a nominally significant reduction in recurrent AMI (p = 0.04) and with trends toward reduced death, rehospitalization for heart failure, and repeat revascularization. Meta-regression suggested the existence of a dose-response association between injected cell volume and LVEF change (p = 0.066). CONCLUSIONS: Intracoronary cell therapy following percutaneous coronary intervention for AMI appears to provide statistically and clinically relevant benefits on cardiac function and remodeling. These data confirm the beneficial impact of this novel therapy and support further multicenter randomized trials targeted to address the impact of intracoronary cell therapy on overall and event-free long-term survival.
