Morgellons disease, illuminating an undefined illness: a case series

Sears C, N. Karlin J. Perceived Conjunctival Foreign Material Egress in Morgellons Disease: A Case Study

The purpose of this report is to present a case of a 63-year-old man with orbital Morgellons disease. A 63-year-old man presented reporting 15 years of daily egress of different foreign bodies apparently found in the superior fornices of both eyes, exhibiting a classic manifestation known as the matchbox sign. He described the symptoms starting after a facial trauma. The patient stated that at several points over the 15-year course of his condition, he was so distressed that he had contemplated suicide. On multiple exams by a range of ophthalmic professionals, there was no evidence of foreign body. Further investigation involving MRI and plain radiographs demonstrated similar lack of findings. A trial of gabapentin was performed without improvement in symptoms. He discontinued care 5 months later. Morgellons disease is a poorly understood condition, particularly ophthalmic presentations of the disease. Despite extensive investigation, the exact cause of Morgellons disease remains unclear, and there is no definitive treatment for the condition. We highlight the importance of empathetic listening in building trust, as a means of helping the patient to seek psychological help.

“Doctor, You Must Examine My Creature Collection!”: A Case Report of Delusional Infestation

Delusional infestation--either secondary when attributed to a medical condition (including a bon-a-fide parasite infestation) or a pharmacologic agent (prescribed or illicit) or primary when secondary etiologies have been excluded--is a psychosis in which, for at least one month duration, the patient not only has a delusion that an animate organism or an inanimate pathogen has infested them, but also has abnormal tactile sensation (such as pruritus) of their skin caused by the etiology of their delusion. In patients over the age of 50 years, a delusional infestation is three times more common in women than men; however, delusional infestation in younger patients is often secondary, associated with illicit drug exposure, and equally common in women and men. Primary skin lesions are typically absent in delusional infestation patients; however, secondary skin lesions--resulting from the patient’s efforts to remove the parasite from their skin--can be observed, such as excoriations, prurigo nodules, scars, and ulcers. Delusional infestation patients typically strive to convince the person evaluating them that their infestation is valid and many of these individuals do this by collecting the parasites in a container. Presentation of the pathogen-filled containers is a pathognomonic feature of delusional infestation that has been referred to as either a positive creature collection sign, match box sign, parasite preservation sign, pillbox sign, or specimen sign. Morgellons disease--in which the pathogen being extruded from the skin is a fiber--has several features (including an excellent response to treatment with antipsychotic agents) in common with delusional infestation; therefore, most investigators consider Morgellons disease to be a variant of delusional infestation. Delusional infestation can be associated with numerous diseases, including comorbid psychiatric conditions. Indeed, up to 15 percent of delusional infestation patients have one (folie a deux) or more individuals with similar symptoms. A man with delusional infestation is described who had a positive creature collection sign, a fixed belief that his symptoms were caused by the infesting organism, and refusal to accept that he had a psychiatric disorder. He insisted that the evaluating dermatologist examine the pathogens in the clear plastic container he brought with him to his appointment. He was convinced that the pruritus of his scalp, eyebrows, and eyelashes was associated with a non-existent lice infestation. Secondary delusional infestation was excluded and his concurrent mild seborrheic dermatitis was treated topically; however, his itching did not resolve. He eventually agreed to seek treatment with a psychiatrist. The management of delusional infestation is based on its etiology; resolving the underlying medical condition or discontinuing the causative pharmacologic agent is the treatment approach for secondary delusional infestation, whereas low-dose antipsychotic agents are the intervention of choice for treating primary delusional infestation.

Clinical evaluation of Morgellons disease in a cohort of North American patients

Morgellons disease (MD) is a dermatological condition characterized by aberrant production of keratin and collagen fibers in skin. Although infection with Borrelia burgdorferi, the causative agent of Lyme disease (LD), has been associated with MD, relatively few studies have hitherto provided epidemiological evidence regarding this association. A cohort of 1000 seropositive North American LD patients was evaluated for the presence of MD. Patients were diagnosed with MD based on detection of microscopic fibers in skin lesions or under unbroken skin. Demographic and clinical features of MD patients were analyzed, and laboratory testing for tickborne coinfections and other infectious agents, was performed. Subjective and objective features of MD were analyzed using statistical methods. Of 1000 seropositive LD patients, 60 (6%) were diagnosed with MD. Of these 60 patients, 75% were female and 78% presented in the late disseminated stage of MD. All 60 patients (100%) were seropositive for B. burgdorferi infection. Tickborne coinfections in these patients included Babesia spp (62%), Bartonella and Rickettsia (25% each), Ehrlichia (15%) and Anaplasma (10%). Helicobacter pylori was detected in 12% of MD patients. In all, 77% of MD patients had one or more coinfections. This study confirms recent findings that MD occurs in a limited subset of LD patients. The clinical and genetic determinants of MD in LD patients require further study.

History of Morgellons disease: from delusion to definition

Morgellons disease (MD) is a skin condition characterized by the presence of multicolored filaments that lie under, are embedded in, or project from skin. Although the condition may have a longer history, disease matching the above description was first reported in the US in 2002. Since that time, the condition that we know as MD has become a polemic topic. Because individuals afflicted with the disease may have crawling or stinging sensations and sometimes believe they have an insect or parasite infestation, most medical practitioners consider MD a purely delusional disorder. Clinical studies supporting the hypothesis that MD is exclusively delusional in origin have considerable methodological flaws and often neglect the fact that mental disorders can result from underlying somatic illness. In contrast, rigorous experimental investigations show that this skin affliction results from a physiological response to the presence of an infectious agent. Recent studies from that point of view show an association between MD and spirochetal infection in humans, cattle, and dogs. These investigations have determined that the cutaneous filaments are not implanted textile fibers, but are composed of the cellular proteins keratin and collagen and result from overproduction of these filaments in response to spirochetal infection. Further studies of the genetics, pathogenesis, and treatment of MD are warranted.

Morgellons disease: experiences of an integrated multidisciplinary dermatology team to achieve positive outcomes

BACKGROUND

In recent years, there has been a reported increase in affliction of the skin with small fibres or other particles. The condition has been referred to as Morgellons disease. Patients present with stinging, burning or crawling sensations of the skin, with perceived extrusion of inanimate material alongside fatigue and other systemic symptoms. Sufferers often experience significant morbidity and reduction in quality of life.

OBJECTIVES

We aimed to explore the various clinical presentations, management strategies and outcomes employed to treat this condition in our patients.

METHODS

We conducted a retrospective case notes review of 35 patients referred to our multidisciplinary psycho-dermatology clinic at the Royal London Hospital between January 2004 and January 2017.

RESULTS

The majority of patients were women (25) 71.4%, with a mean age of 54.6 years (26-80 years). Most (26) 74.2% were living alone. The average duration of illness prior to presentation was 3.8 years (4 months-20 years). Many patients had perceived precipitating factors (54.2%) and often self-diagnosed (28.5%). Psychiatric co-morbidities included 42.8% with depressive symptoms and 25.7% with anxiety. Substance misuse was elicited in five patients (14%). Management of patients included both the treatment of skin disease and psychosocial co-morbidities. Out of the 35 patients who attended (14) 40% cleared or showed significant improvement. Sixteen (45.7%) patients were stable and under review. One patient declined treatment and three did not attend review. One patient died from disease unrelated to her skin condition.

CONCLUSIONS

Morgellons disease is a condition, which is widely discussed on the internet and patients often self-diagnose. The course of the disease can be chronic and debilitating. For a positive outcome, it is important that a strong physican-patient relationship is cultivated. As demonstrated in this case series, managing patients holistically in an integrated multidisciplinary dermatology setting helps achieve positive outcomes.

Morgellons disease: a filamentous borrelial dermatitis

Morgellons disease (MD) is a dermopathy characterized by multicolored filaments that lie under, are embedded in, or project from skin. Although MD was initially considered to be a delusional disorder, recent studies have demonstrated that the dermopathy is associated with tickborne infection, that the filaments are composed of keratin and collagen, and that they result from proliferation of keratinocytes and fibroblasts in epithelial tissue. Culture, histopathological and molecular evidence of spirochetal infection associated with MD has been presented in several published studies using a variety of techniques. Spirochetes genetically identified as Borrelia burgdorferi sensu stricto predominate as the infective agent in most of the Morgellons skin specimens studied so far. Other species of Borrelia including Borrelia garinii, Borrelia miyamotoi, and Borrelia hermsii have also been detected in skin specimens taken from MD patients. The optimal treatment for MD remains to be determined.

Information, consent and treatment of patients with Morgellons disease: an ethical perspective

Morgellons is a medically contested diagnosis with foremost dermatological symptoms. Patients experience fibers emerging from the skin, together with a range of other somatic, psychiatric, and neurological complaints. Within the medical community, it is generally held to be a variation of delusional parasitosis/delusional infestation, which is usually treated with antipsychotics. Little attention has been paid in the literature to the ethical aspects of treating patients with Morgellons disease. The communicative strategies suggested in the literature display significant ethical issues, primarily the use of therapeutic privilege, i.e. withholding information from the patient. Since this limits patient autonomy, that approach is ethically problematic. Instead, the physician has an ethical obligation to respect the patient's autonomy, provide full information, and seek consent before initiating a psychiatric referral.

Variable clinical presentations of secondary delusional infestation: an experience of six cases from a psychodermatology clinic

OBJECTIVE

Delusional Infestation (DI) is a relatively rare condition with a fixed belief of being infested with living organisms, despite a lack of medical evidence of such infestation. Although it seems to be a psychiatric disease, patients commonly are admitted to dermatology clinics because of skin findings. Psychiatrists can underestimate its prevalance, whereas dermatologists can miss the diagnosis. It should be managed as a psychodermatological disease. Our aim in the study was to evaluate six patients with different clinical presentations of DI and to emphasize some clinical features.

METHOD

All patients were internalized in the psychodermatology clinic for this study. Medical history and clinical data from dermatologic and psychiatric examinations were noted; Mini International Neuropsychiatric Interview (MINI-Plus) and laboratory investigations including blood and urine analyses, microscopic analysis of so-called pathogens, and skin biopsy if needed, were performed. The diagnosis was made based on detailed history, dermatologic and psychiatric examinations, and laboratory investigations.

RESULTS

All patients had symptoms of itching, burning, or crawling sensations dermatologically and thus were admitted to dermatology clinic. They were all considered secondary DI to another medical condition or to psychiatric illness. Vitamin B12 deficiency, diabetes, and hypothyroidism were the underlying medical conditions. Related psychiatric illnesses were trichotillomania and schizoaffective disorder, schizophrenia, shared pychotic disorder, and brief psychotic disorder. Two patients had delusions of inanimate materials; four patients had partial and complete remissions; and two patients have dropped out.

CONCLUSION

Each patient had different clinical characteristics creating diagnostic challenges. All complaints were related to the infestation of the skin. The presence of different psychiatric comorbidities is remarkable. It seems that both psychiatrists and dermatologists can face diagnostic and therapeutic challenges of this complex disease in clinical settings, particularly if there are unusual clinical features of DI. Therefore, both psychiatrists and dermatologists should be well aware of DI.

Psychosomatic factors in pruritus

Pruritus and psyche are intricately and reciprocally related, with psychophysiological evidence and psychopathological explanations helping us to understand their complex association. Their interaction may be conceptualized and classified into 3 groups: pruritic diseases with psychiatric sequelae, pruritic diseases aggravated by psychosocial factors, and psychiatric disorders causing pruritus. Management of chronic pruritus is directed at treating the underlying causes and adopting a multidisciplinary approach to address the dermatologic, somatosensory, cognitive, and emotional aspects. Pharmcotherapeutic agents that are useful for chronic pruritus with comorbid depression and/or anxiety comprise selective serotonin reuptake inhibitors, mirtazapine, tricyclic antidepressants (amitriptyline and doxepin), and anticonvulsants (gabapentin, pregabalin); the role of neurokinin receptor-1 antagonists awaits verification. Antipsychotics are required for treating itch and formication associated with schizophrenia and delusion of parasitosis (including Morgellons disease).

Characterization and evolution of dermal filaments from patients with Morgellons disease

Morgellons disease is an emerging skin disease characterized by formation of dermal filaments associated with multisystemic symptoms and tick-borne illness. Some clinicians hypothesize that these often colorful dermal filaments are textile fibers, either self-implanted by patients or accidentally adhering to lesions, and conclude that patients with this disease have delusions of infestation. We present histological observations and electron microscopic imaging from representative Morgellons disease samples revealing that dermal filaments in these cases are keratin and collagen in composition and result from proliferation and activation of keratinocytes and fibroblasts in the epidermis. Spirochetes were detected in the dermatological specimens from our study patients, providing evidence that Morgellons disease is associated with an infectious process.

Clinical, epidemiologic, histopathologic and molecular features of an unexplained dermopathy

BACKGROUND

Morgellons is a poorly characterized constellation of symptoms, with the primary manifestations involving the skin. We conducted an investigation of this unexplained dermopathy to characterize the clinical and epidemiologic features and explore potential etiologies.

METHODS

A descriptive study was conducted among persons at least 13 years of age and enrolled in Kaiser Permanente Northern California (KPNC) during 2006-2008. A case was defined as the self-reported emergence of fibers or materials from the skin accompanied by skin lesions and/or disturbing skin sensations. We collected detailed epidemiologic data, performed clinical evaluations and geospatial analyses and analyzed materials collected from participants' skin.

RESULTS

We identified 115 case-patients. The prevalence was 3.65 (95% CI = 2.98, 4.40) cases per 100,000 enrollees. There was no clustering of cases within the 13-county KPNC catchment area (p = .113). Case-patients had a median age of 52 years (range: 17-93) and were primarily female (77%) and Caucasian (77%). Multi-system complaints were common; 70% reported chronic fatigue and 54% rated their overall health as fair or poor with mean Physical Component Scores and Mental Component Scores of 36.63 (SD = 12.9) and 35.45 (SD = 12.89), respectively. Cognitive deficits were detected in 59% of case-patients and 63% had evidence of clinically significant somatic complaints; 50% had drugs detected in hair samples and 78% reported exposure to solvents. Solar elastosis was the most common histopathologic abnormality (51% of biopsies); skin lesions were most consistent with arthropod bites or chronic excoriations. No parasites or mycobacteria were detected. Most materials collected from participants' skin were composed of cellulose, likely of cotton origin.

CONCLUSIONS

This unexplained dermopathy was rare among this population of Northern California residents, but associated with significantly reduced health-related quality of life. No common underlying medical condition or infectious source was identified, similar to more commonly recognized conditions such as delusional infestation.

An oral ulceration associated with Morgellons disease: a case report

Morgellons disease is a psycho-dermatologic condition in which patients report fibers or filaments "growing" out of their skin. This case report highlights an oral ulceration in a young woman associated with Morgellons disease, a condition that has not been previously described in the dental literature. An increasing number of individuals are self-reporting this condition and oral health care providers must be familiar with this disorder.

Morgellons disease and delusions of parasitosis

Morgellons disease is a controversial and poorly defined symptom cluster of skin lesions and somatic symptoms, most notably 'fibers' in the skin. Because of widespread coverage in the media and on the Internet, there are an increasing number of patients presenting to dermatologists. We present three patients who believed that they had fibers in their skin. We offer a discussion of delusions of parasitosis to demonstrate similarities between these conditions. It has been suggested by a limited number of healthcare providers that an unknown infectious agent underlies this symptom complex yet no available evidence supports this assertion. Laboratory values that would be reflective of an infectious process (e.g. elevated white blood cells, sedimentation rate, C reactive protein) are routinely normal and biopsies often reflect only nonspecific findings such as acute and chronic inflammation with erosion or ulceration. Patients with Morgellons disease generally lack insight into their disease and reject the need for psychiatric help. The goal is to build trust and refrain from minimizing what the patient experiences. Attentive examination of the patient's skin and fragments they present is necessary to rule out a true underlying pathologic process and to establish a trusting relationship. A supportive, non-confrontational approach is ideal. The patient is best treated by a team of practitioners of several specialties, including dermatologists, psychiatrists, and counselors.
