A case of factitious aplastic anemia

[Factitious disorder imposed on self and Munchausen syndrome: An update]

Factitious disorder imposed on self (FDIS) is a mental disorder characterized by conscious manipulative behavior from patients with no clearly identifiable external objective. It affects subjects with a wide range of characteristics, only some of whom fit the stereotypical profile of the young female working in the health sector. It can take the form of a variety of symptoms or clinical signs, and is likely to involve all specialties. Munchausen syndrome is a particular form of FDIS, more prevalent in men and marked by its severity. Psychiatric comorbidities are common in patients with FDIS. Death is rare but possible, either as a result of the disease itself, complications of examinations or treatments, or suicide. The diagnostic approach must seek to identify positive arguments in favor of the disorder. Diagnosis by elimination remains possible when no other hypothesis can explain a clinical picture suggestive of FDIS. The prognosis is often poor, at least in the short and medium term. Avoiding unnecessary prescriptions is essential to prevent iatrogenesis. The management of FDIS is poorly codified. In all cases, the practitioner must adopt a non-aggressive, empathetic attitude.

Factitious disorder imposed on self: A retrospective study of 2232 cases from health insurance databases

OBJECTIVE

Patients with factitious disorder imposed on self (FDIS) seek medical care for deliberately falsified problems. Although a large amount of work has been published, the scientific literature lacks robust data on FDIS. The present study aimed to estimate the annual mean of in-hospital FDIS codings in France, describe the sociodemographic characteristics of subjects with FDIS, assess healthcare utilisation and medical nomadism, and describe the pathologies most frequently associated with FDIS.

METHOD

Subjects with at least one coding of FDIS in French health insurance databases between January 1, 2009, and December 31, 2017 were included. Subjects younger than 18 years of age at the time of first coding were excluded from the study. Sociodemographic data of subjects and diagnoses associated with the first coding of FDIS were collected. Healthcare utilisation and medical nomadism were analysed descriptively from one year before to one year after the first FDIS coding.

RESULTS

2232 subjects were included, representing an average of 248 new in-hospital FDIS codings per year. The subjects included were 58.2% female. The mean age at diagnosis was 48.5 years. In the year following the first coding of FDIS, 1268 subjects (56.8%) were re-hospitalised at least once, including 159 (7.1%) with at least one new coding for FDIS. From one year before to one year after the first coding of FDIS, 66% of the subjects included had received at least one prescription for benzodiazepines, 58.3% for antidepressants, and 42.6% for antipsychotics.

CONCLUSIONS

Our findings bring new data working towards a better understanding of FDIS. The consumption of psychotropic drugs is particularly frequent in patients with FDIS.

A Diagnostic Dilemma: Is It Factitious Disorder With Nonepileptic Seizure or Malingering With Nonepileptic Seizure?

In reality, the lines between factitious disorder, functional disorder, and malingering are quite blurred. In factitious disorder and malingering, patients consciously and deliberately create false medical and/or psychiatric symptoms for self-gain, often approaching multiple healthcare facilities to evade detection. Although the factitious disorder is pervasive, and the literature lacks accurate and consistent information, comorbidity with nonepileptic seizure (NES, a component of functional disorder) is quite commonly documented. In our case, the patient feigned multiple symptoms including two seizures and a shoulder dislocation to gain access to opioids. The clinical picture was only significant for alcohol withdrawal, aspiration pneumonia (possibly intubation vs. NES-related), and self-induced shoulder dislocation. Generally, management of these disorders should involve multiple specialties, multiple approaches, and identifying the triggering and comorbid psychological disorders, such as abandonment issues, personality disorders, physical or emotional abuse, anxiety, depression, stress, and substance use. Blindly approaching patients with a factitious disorder or malingering will not lead to any productive outcomes. Perhaps, creating a patient database could help reduce futile efforts while providing patients with the required help. This case report describes the presentation, diagnosis, management, and outcomes related to a patient with NES, engaging the reader to decipher the most appropriate diagnosis.

A Fatal Case of Factitious Aplastic Anemia

We report the case of a 26-year-old female who intentionally ingested busulfan, an oral chemotherapy agent, to induce severe aplastic anemia. The patient was initially thought to be suffering from idiopathic aplastic anemia, before clues suggesting the diagnosis of a factitious disorder were identified. The patient underwent a bone marrow transplant and ultimately died 5 weeks later following a lengthy admission to the intensive care unit. It is unclear whether confrontation about a patient's self-induction of physical illness is beneficial in the treatment of patients with factitious disorder. Cases such as this pose substantial diagnostic challenges, making early recognition of factitious disorder and initiation of treatment difficult. The patient described in this case report had risk factors for a factitious disorder, including age, gender, professional involvement in health care, recent loss and developmental trauma. Factitious disorder, while rare, can have lethal consequences for the patient. This diagnosis must be considered as part of a full diagnostic assessment.

Residual effects of busulfan and irradiation on murine hematopoietic stem and progenitor cells

Exposure of young C57BL/6 (B6) mice to two courses of busulfan (BSF) injections or two rounds of sublethal total-body irradiation (TBI) induced significant damage to the function of hematopoietic stem and progenitor cells (HSPCs). Fifteen weeks after treatment, BSF- and TBI-treated mice had reduced white blood cells without significant change in red blood cells or platelets, indicating that BSF and TBI hematotoxicity was chronic, with leukocytes being the major targets. Hematopoietic damage induced by BSF or TBI persisted long term. Residual adverse effects were reflected by significantly decreased CD45R B cells and reduced recovery of total bone marrow cells, especially HSPCs carrying markers for KSL (Kit⁺Sca-1⁺Lin^-) cells, multipotent progenitor (MPP) cells (KSLCD34⁺CD135⁺), myeloid progenitor (MP) cells (Kit⁺Sca-1^-Lin^-), and common lymphoid progenitor (CLP) cells 62 wk posttreatment. Transplantation of bone marrow (BM) cells from BSF and TBI donors at 49 weeks after treatment into lethally irradiated hosts resulted in decreased engraftment of CD45R B cells in blood and reduced reconstitution of BM HSPCs including KSL cells, short-term hematopoietic stem cells (KSLCD34⁺CD135^-), MPP cells, and MP cell subsets. TBI donor had better reconstitution of CLP cells in recipients posttransplantation than did BSF donor, suggesting an impact of TBI and BSF on B cells at different development stages. In summary, BSF and TBI exposure produced long-lasting adverse effects on hematopoiesis with pronounced effects on mature B cells, immature ST-HSCs, and hematopoietic progenitor cells. Our results may have implications for therapy of human diseases.

Striving to Die: Medical, Legal, and Ethical Dilemmas Behind Factitious Disorder

Factitious disorder (FD) imposed on self is one of the most challenging and controversial problems in medicine. It is characterized by falsified medical or psychiatric symptoms where patients misrepresent, simulate, or cause symptoms of an illness in the absence of obvious tangible gains. Munchausen syndrome accounts for approximately 10% of all factitious illnesses and represents its most malignant form. An unknown number of deaths have likely occurred when considering that most cases go unrecognized and unreported. Here we describe a case in which the patient’s condition remained unrecognized, only being diagnosed months before her death from complications of FD.

Psychiatry was consulted to see a 49-year-old Caucasian female regarding depression, poor oral intake, and her insistence on the placement of a feeding tube. The initial evaluation was negative for findings consistent with psychiatric illness. A review of records in our hospital was significant for one previous psychiatric inpatient stay eight months prior during which a diagnosis of FD imposed on self was made. Collateral information suggested a cycle of deception and simulation of illnesses with the patient’s daughter labeling her actions as “doctor shopping.” At our facility alone, she had accrued roughly 40 inpatient medical admissions and 70 ED visits in four years though only two encounters involving Psychiatry. A detailed chronological analysis of her records showed the only documented concern of deception to be that of an Internal Medicine resident two years prior. Psychiatry was not consulted despite this concern. During the present encounter, psychiatry recommended ethics consult, outpatient psychotherapy, and frequent follow-ups with primary care. A formal ethics consult was not completed before discharge. Within two months, the patient died at another facility. 

FD can lead to diagnostic and therapeutic procedures that result in irreversible morbidity and iatrogenic harm. Physicians in other medical specialties often suspect a patient of consciously deceiving others, though fail to assign psychiatric nomenclature due to lack of familiarity or comfort in making the diagnosis. This further substantiates the role of a multidisciplinary collaboration between medical, surgical, and psychiatry teams. Heightened awareness of, and suspicion for, Munchausen syndrome may improve rates of diagnosis and prognosis of these patients.

Epidemiology and evolution of the diagnostic classification of factitious disorders in DSM-5

A systematic search for all case reports and case series of adult patients with factitious disorders (FD) in the databases MEDLINE, Scopus, and PsycINFO was conducted. FD is a psychiatric disorder in which sufferers intentionally fabricate physical or psychological symptoms in order to assume the role of a patient, without any obvious gain. The clinical and demographic profile of patients with FD has not been sufficiently clear. Thus, the aims of this study were to outline a demographic and clinical profile of a large sample of patients with FD and to study the evolution of the position of FD in the Diagnostic and Statistical Manual of Mental Disorders. One thousand six hundred thirty-six records were obtained based on key search terms, after exclusion of duplicate records. Five hundred seventy-seven articles were identified as potentially eligible for the study, of which 314 studies were retrieved for full-text review. These studies included 514 cases. Variables extracted included age, gender, reported occupation, comorbid psychopathology, clinical presentation, and factors leading to the diagnosis of FD. In the sample, 65.4% of patients were females. Mean age at presentation was 33.5 years. A health care profession was reported most frequently (n=113). Patients were most likely to present in psychiatry, neurology, emergency, and internal medicine departments. The broad survey of sociodemographic profile of the sample has highlighted some important points for early diagnosis and early psychiatric treatment. The study showed that the patients did not meet Diagnostic and Statistical Manual of Mental Disorders-5 diagnostic criteria in 11.3% of cases.

Can factitious disorder reach delusional level? A case study

The paper describes a patient, who has been consulted and hospitalized multiple times, due to dermatological lesions on his face. We will present his medical history and describe circumstances leading to the final diagnosis of factitious disorder. In the theoretical part we will try to answer the question, whether the extreme severity of the factitious disorders can, at some point, reach the level of delusions.

Factitious disorder: a systematic review of 455 cases in the professional literature

OBJECTIVE

Patients with factitious disorder (FD) fabricate illness, injury or impairment for psychological reasons and, as a result, misapply medical resources. The demographic and clinical profile of these patients has yet to be described in a sufficiently large sample, which has prevented clinicians from adopting an evidence-based approach to FD. The present study aimed to address this issue through a systematic review of cases reported in the professional literature.

METHOD

A systematic search for case studies in the MEDLINE, Web of Science and EMBASE databases was conducted. A total of 4092 records were screened and 684 remaining papers were reviewed. A supplementary search was conducted via GoogleScholar, reference lists of eligible articles and key review papers. In total, 372 eligible studies yielded a sample of 455 cases. Information extracted included age, gender, reported occupation, comorbid psychopathology, presenting signs and symptoms, severity and factors leading to the diagnosis of FD.

RESULTS

A total of 66.2% of patients in our sample were female. Mean age at presentation was 34.2 years. A healthcare or laboratory profession was reported most frequently (N=122). A current or past diagnosis of depression was described more frequently than personality disorder in cases reporting psychiatric comorbidity (41.8% versus 16.5%) and more patients elected to self-induce illness or injury (58.7%) than simulate or falsely report it. Patients were most likely to present with endocrinological, cardiological and dermatological problems. Differences among specialties were observed on demographic factors, severity and factors leading to diagnosis of FD.

CONCLUSIONS

Based on the largest sample of patients with FD analyzed to date, our findings offer an important first step toward an evidence-based approach to the disorder. Future guidelines must be sensitive to differing methods used by specialists when diagnosing FD.

Factitious disorder (Munchausen's syndrome) in oncology: case report and literature review

BACKGROUND

Factitious disorder is where patients repeatedly seek medical care for feigned illnesses in the absence of obvious external rewards; 'Munchausen's syndrome' is the historical name for this disorder.

METHOD

We report on a case that was presented to a tertiary oncology center as a suspected rare bone cancer.

RESULTS AND CONCLUSIONS

Psychosocial clinicians working in oncology settings should be aware of the complexities of diagnosing factitious disorder in cancer settings where empathy is prominent and suspicion unusual. Moreover, comorbidity can cloud the diagnosis (in this case substance abuse), and, even when accurately diagnosed, there are no evidence-based management approaches to offer to the patient. What seems to linger most after the patient is discharged, usually in a huff, are strong counter-transference feelings and substantial medical bills. Copyright © 2015 John Wiley & Sons, Ltd.

Haemotoxicity of busulphan, doxorubicin, cisplatin and cyclophosphamide in the female BALB/c mouse using a brief regimen of drug administration

Many anticancer drugs are myelotoxic and cause bone marrow depression; however, generally, the marrow/blood returns to normal after treatment. Nevertheless, after the administration of some anti-neoplastic agents (e.g. busulphan, BU) under conditions as yet undefined, the marrow may begin a return towards normal, but normality may not be achieved, and late-stage/residual marrow injury may be evident. The present studies were conducted to develop a short-term mouse model (a 'screen') to identify late-stage/residual marrow injury using a brief regimen of drug administration. Female BALB/c mice were treated with BU, doxorubicin (DOX), cisplatin (CISPLAT) or cyclophosphamide (CYCLOPHOS) on days 1, 3 and 5. In 'preliminary studies', a maximum tolerated dose (MTD) for each drug was determined for use in 'main studies'. In main studies, mice were treated with vehicle (control), low and high (the MTD) dose levels of each agent. Necropsies were performed, and blood parameters and femoral/humeral nucleated marrow cell counts (FNCC/HNCC) were assessed on six occasions (from days 1 to 60/61 post-dosing). Late-stage/residual changes were apparent in BU-treated mice at day 61 post-dosing: RBC, Hb and haematocrit were reduced, mean cell volume/mean cell haemoglobin were increased and platelet and FNCC counts were decreased. Mice given DOX, CISPLAT and CYCLOPHOS, in general, showed no clear late-stage/residual effects (day 60/61). It was concluded that a brief regimen of drug administration, at an MTD, with assessment at day 60/61 post-dosing was a suitable short-term method/screen in the mouse for detecting late-stage/residual marrow injury for BU, a drug shown to exhibit these effects in man.

Review article: psychological aspects of home parenteral nutrition, abnormal illness behaviour and risk of self-harm in patients with central venous catheters

BACKGROUND

Home parenteral nutrition is established as standard management for patients with chronic severe intestinal failure. Although the treatment is welcomed by many patients, there are psychological consequences of living with a central venous catheter and there are associated restrictions to the lives of patients on home parenteral nutrition. A subgroup of home parenteral nutrition patients may use their central venous catheter for self-harm.

AIMS

To review existing literature relating to abnormal psychological responses to central venous catheters in patients receiving home parenteral nutrition and the psychological meaning of living with a central venous catheter. It also attempts to alert professionals to ways in which patients may self-harm using their central venous catheters.

METHODS

A literature review was performed. Data were obtained both from literature searches and from personal experience at a Psychological Medicine Unit attached to a large home parenteral nutrition centre.

RESULTS

Patients receiving home parenteral nutrition may use their central venous catheter in various ways to self-harm. Motivation may be conscious or unconscious. Sequelae of such self-harm may be life-threatening.

CONCLUSION

This paper concludes with recommendations for best practice with respect to the psychological management of home parenteral nutrition patients in whom central venous catheter abuse is suspected.

Serum FLT-3 ligand in a busulphan-induced model of chronic bone marrow hypoplasia in the female CD-1 mouse

The concentration of the cytokine fms-like tyrosine kinase-3 ligand (FL) is elevated in the plasma of patients treated with chemotherapy or radiotherapy for malignant conditions. In addition, plasma FL is increased in patients with bone marrow failure resulting from stem-cell defects (e.g. aplastic anaemia). Our goal in the present study was to measure the concentration of serum FL in mice treated with the chemotherapeutic agent busulphan (BU) to induce bone marrow depression and relate changes in FL to effects on haemopoiesis. Female CD-1 mice were treated with BU (9.0 mg/kg) or vehicle by intraperitoneal injection on 10 occasions over 21 days. Animals were autopsied on days 1, 23, 72, 119 and 177 postdosing. A full blood count was performed, and serum prepared for FL analysis. Femoral marrow cell suspensions were prepared to assess the total femoral nucleated cell count (FNCC) and the number of committed haemopoietic progenitor cells (CFU-C). On days 1 and 23 postdosing, significant decreases were evident in many peripheral blood parameters; the FNCC and CFU-C were also reduced in BU-treated mice, in conjunction with increases in serum FL levels. On days 72, 119 and 177 postdosing, several peripheral blood and bone marrow parameters remained reduced and the concentration of serum FL continued to be significantly increased. Linear regression analysis demonstrated significant correlations between the concentration of serum FL in BU-treated mice and peripheral blood and bone marrow parameters; this suggests the possible use of serum FL as a potential biomarker for drug-induced bone marrow injury.
