Isolated herpes simplex in the adult larynx as a rare complication of methotrexate-induced immunosuppression

Herpes simplex laryngitis: Comparison between pediatric and adult patients

OBJECTIVES

Infection with herpes simplex virus (HSV) typically causes limited oral and genital symptoms, however HSV can also affect the larynx and result in severe aerodigestive symptoms. Due to the rarity of HSV laryngitis, the symptoms and clinical course of are not well understood. This study aims to more completely characterize HSV laryngitis in order to aid clinicians in understanding and recognition of HSV laryngitis.

METHODS

Comprehensive literature search of MEDLINE, EMBASE, and Cochrane Database of Systematic Reviews to identify articles relating to HSV laryngitis. Patient demographics, presenting signs and symptoms, treatment and clinical course were extracted from the selected manuscripts.

RESULTS

There were 31 studies on HSV laryngitis that identified 36 patients (17 pediatric, 19 adult). The average age for pediatric patients was 11 months (9 M, 8F) and 52 years for adults (11 M, 8F). In the pediatric population, stridor was more common at presentation in comparison to the adult population (p < .01). Adults more commonly presented with dysphagia (p = .03) and dysphonia (p < .01) Adult patients were significantly more likely to undergo tracheotomy than pediatric patients (p = .047). The mean length of inpatient hospital stay was 21.2 days in pediatric patients and 15.8 days for adult patients.

CONCLUSION

HSV laryngitis has a unique presentation in pediatrics and adults, but is nonspecific in both populations leading to delays in diagnosis and treatment. HSV laryngitis is associated with significant morbidity including multi-week hospital stay and risk for needing tracheostomy in both adults and pediatric population which demonstrates need for clinical awareness of this complication of HSV infection.

Disseminated Herpes Simplex Infection Presenting as Acute Supraglottitis in an Adult

Supraglottitis is a life-threatening, predominantly bacterial disease that is rarely caused by viral etiologies. Herpes Simplex Virus (HSV) supraglottitis has been infrequently reported, but its presentation can mimic that of bacterial supraglottitis or pharyngitis which may lead to delayed diagnosis and increased morbidity. We present a case of supraglottitis in an immunocompetent man initially thought to have bacterial epiglottitis. After receiving a tracheostomy due to impending airway compromise and failing to improve on antibiotic therapy, biopsy of the upper airway tissue revealed infection with HSV type 2. The patient improved after multiple weeks of systemic antivirals. HSV supraglottitis remains an unusual but important diagnostic consideration in patients with dysphonia, dysphagia, ulcerative supraglottal lesions, and acute supraglottic inflammation unresponsive to antibiotics.

Intralesional Cidofovir for Treatment of Acyclovir-Resistant Laryngeal Herpes Manifesting as Supraglottic Mass

INTRODUCTION:

Laryngopharyngeal herpes simplex virus infection is rare and presents typically in the supraglottis. Findings on presentation can range from small mucosal lesions to fungating obstructive masses mimicking neoplasm. Laryngopharyngeal herpes is a medically treated disease.

OBJECTIVES:

Identify potential treatment in cases that are refractory to antiviral medications.

METHODS:

Individual case with treatment adapted from other case report.

CASE PRESENTATION:

We report a case of bulky, obstructive supraglottic and glottic herpes virus laryngitis that presented with dysphonia, dysphagia, and airway complaints resistant to acyclovir analogues that was treated effectively with intralesional cidofovir injection.

CONCLUSIONS:

Our promising initial response suggests a potential novel treatment for this unusual condition.

Cancer chemotherapeutics in rheumatoid arthritis: A convoluted connection

Chemotherapy is one of the most popular therapeutic strategies to treat cancer. However, cancer chemotherapeutics have often been associated with impairment of the immune system, which might consequently lead to an augmented risk of autoimmune disorders, such as rheumatoid arthritis. Though the accurate mechanistic facets of rheumatoid arthritis induction have not been interpreted yet, a conglomeration of genetic and environmental factors might promote its etiology. What makes the scenario more challenging is that patients with rheumatoid arthritis are at a significantly elevated risk of developing various types of cancer. It is intriguing to note that diverse cancer chemotherapy drugs are also commonly used to treat symptoms of rheumatoid arthritis. However, a colossal multitude of such cancer therapeutics has demonstrated highly varied results in rheumatoid arthritis patients, including both beneficial and adverse effects. Herein, we attempt to present a holistic account of the variegated modalities of this complex tripartite cross-talk between cancer, rheumatoid arthritis and chemotherapy drugs in order to decode the sinuous correlation between these two appalling pathological conditions.

Herpes Simplex Virus Laryngitis Presenting as Airway Obstruction: A Case Report and Literature Review

OBJECTIVES

Herpes simplex virus (HSV) laryngitis is rare in adults. We add a case report to the literature and perform a literature review to further delineate the clinical presentation, course, and treatment of HSV laryngitis in adults.

METHODS

Case report and literature review using PubMed and Ovid databases.

RESULTS

Ten cases of diagnosed HSV laryngitis in adults were reported in the literature. It is more common in immunocompromised patients. The mean patient age was 51 years with a male to female ratio of 1:1. The clinical presentation and course of HSV laryngitis is variable. Patients may have mild chronic symptoms, such as dysphonia, or a fulminant course with rapid airway compromise. On laryngoscopic exam, the most common findings are a white exudate or ulceration. The most common treatment is with antiviral medication, such as acyclovir, which tends to be highly effective.

CONCLUSIONS

Herpes simplex virus laryngitis is rare. Clinical presentation of HSV laryngitis is variable, and its course may be indolent or fulminant. Treatment with antiviral medication tends to be highly effective.
