Gamekeeper’s or skier’s thumb is caused by an injury to the ulnar collateral ligament (UCL) of the metacarpophalangeal (MCP) joint of the thumb. The mechanism of injury is forced radial and palmar abduction and hyperextension.

This lesion was initially described in 1955 by Campbell.¹ It occurred in gamekeepers who worked in preserves in Scotland. The UCL was injured because of the way they killed rabbits—hence, gamekeeper’s thumb. Now these injuries are more common in skiers—skier’s thumb. In skiers, the mechanism of injury is the force exerted by the ski pole strap on the thumb during a fall. This injury is also seen in breakdancers.^1,2

Different lesions can result, the most common being that of the UCL. The UCL lesion may be partial, with no joint instability,^3,4 or total, with instability and subdislocation of the proximal phalanx.^5-9 Rupture of the thumb adductor aponeurosis and displacement of the long extensor have been described as the cause of thumb instability.^6-8

UCL rupture can occur in its extension or can cause a fracture-tearing in the proximal phalanx.^9-12 Intra-articular fractures are sometimes found. The essential problem in UCL injuries is the impossibility of spontaneous healing once the rupture is complete, because of the Stener effect. (When the UCL ruptures, its proximal part retracts and runs above the fibrous expansion of the adductor muscle, which is interposed between the 2 parts of the ruptured UCL and prevents healing, even if the thumb is immobilized.) In these cases, only surgery can repair the lesion.²

In any thumb injury, particularly one caused by hyperabduction, a UCL lesion should be considered. The main problem is diagnosing sprain severity, which is evidenced by the degree of joint hypermobility. Radiologic examination should be performed in all cases to rule out fracture with tear, posterior capsular tear, palmar plate tear, and palmar subdislocation of the proximal phalanx, all of which are associated with UCL tearing.^7-9

If the diagnosis is suspected, and radiographs show no fracture, comparative radiographs should be obtained in forced valgus.

Technique

We report on a simple, reliable, reproducible method that allows the patient’s thumbs to be compared, under the same force application conditions, on a single radiograph. This technique reduces the patient’s and examiner’s exposure to x-rays and is well tolerated by the patient. Anesthesia for the thumb is usually not necessary.

In each hand, the patient holds a cylindrical object, such as a drinking glass (standard diameter, 7.5-8.5 cm). We use an elastic crepe bandage roll (diameter, 7.5 cm; width, 10 cm). This roll is common in emergency departments (EDs) and easily accessible. The patient holds the rolls in his or her hands with the thumbs in the posteroanterior position (Figures 1–3) and places himself or herself on a 18×24-cm frame or directly on the radiography table.

Both thumbs are captured on a single functional radiograph for comparison of forced valgus of the MCP joints, as in our example cases. The patients provided written informed consent for print and electronic publication of these case reports.

Case Reports

Control Case

The single functional radiograph of both thumbs showed no evidence of joint laxity on the valgus stress test (Figure 4).

Case 1

A 72-year-old woman landed on her left hand when she fell backward while supporting the hand on a piece of furniture. She presented to the ED with pain in the region of the thumb and thenar eminence. Posteroanterior and lateral radiograph projections showed no significant bone injury (Figure 5). Given the patient’s persistent pain, the traumatologist suspected damage to the thumb UCL, so a simultaneous bilateral functional radiographic projection was obtained. The projection showed joint laxity, implying damage to the thumb UCL. Repair and reinsertion of the UCL were performed using a bone harpoon suture.

Case 2

A 58-year-old man sustained a left hand injury when, using both hands, he tried to catch hold of a falling wooden plank. When he presented to the ED the following week, he was given a diagnosis of thumb contusion and forced hyperabduction and was wearing a metal strap for immobilization. Radiographs showed no bone damage (Figure 6). Thumb UCL injury was suspected on the basis of the physical examination findings and the mechanism of injury. A bilateral simultaneous functional radiographic projection showed significant joint laxity. Surgical treatment with the pull-out technique was performed.

Case 3

A 44-year-old woman experienced forced traction from a dog leash and presented to the ED with pain in the right thumb region. Radiographs showed no bone damage (Figure 7). Thumb UCL injury was suspected. A bilateral simultaneous functional radiographic projection showed slight joint laxity, a sprain was diagnosed, and plaster bandaging was applied. Figures 8A–8D show the accurate thumb positions for performing the functional radiograph in forced valgus. We call the technique J.J.’s thumb radiographic projection.

Discussion

Examination using the stress test to cause joint tilt is crucial in making an accurate diagnosis and deciding on the most appropriate therapeutic approach.¹⁰ Most authors accept that surgical management is required in joint tilts over 30º, as these involve complete UCL rupture.^10-12

The MCP joint must be examined in flexion, when the main fascicle of the UCL is tight, and not in extension, when the main fascicle of the UCL is relaxed. If we examine the thumb in extension, radial deviations may occur that are not caused by joint instability. Tilt here must be compared with that of the healthy side.¹¹

Early diagnosis and adequate management are essential, as unnoticed or undervalued injuries can progress to painful sequelae, associated with stiffness, instability, and osteoarthritis, with evident harm to the grip and pinch functions of the hand. In many cases, clinical evidence of MCP joint instability is difficult. The radiologic diagnosis is usually obtained with comparative radiographs in forced valgus of both thumbs.

The forced valgus maneuver typically is performed by the examiner, who must stay with the patient in the radiography room and wear radiologic protection. Incredibly, some patients must force the valgus themselves.

The maneuver we have described clearly has complications, as it is painful, and some patients are uncooperative. Usually the thumb is anesthetized, and the examiner assumes the exposure to x-rays. The valgus deviation force that can be applied during stability testing may lead to further disruption of a partially torn ligament or displacement of a ruptured ligament if the overforced maneuver is performed.^13,14 That does not occur with our technique. On the other hand, the forces applied to the thumbs must be symmetrical for comparison purposes. The way to prevent these inconveniences is to perform the forced valgus maneuver over both thumbs simultaneously, under the same force application conditions and on a single radiograph, without requiring the examiner to remain with the patient in the radiography room.

Heim¹⁵ designed a system for simultaneous functional radiographs, but an apparatus must be built to adapt it to the frame of the radiography table, and the technique involves hyperpronating both hands and bandaging them to the forearm—which is uncomfortable and bothersome for patients and, in our opinion, has a poor application in high-volume EDs.

The technique of having the patient hold a bandage roll (J.J.’s thumb radiographic projection) offers several advantages:

1.  The thumb can be placed in flexion, tightening the main fascicle of the UCL, which is how the UCL must be examined.

2. Forced valgus is allowed. Holding a water glass involves opening the thumb and the necessary stability of the MCP joint of the thumb (grip function of thumb); this radiographic technique is functional.

3. The examiner need not stay with the patient in the radiography room or be exposed to x-rays.

4. The bandage roll is thick enough to generate forced valgus in a patient with large hands. The nonrigid roll makes the examination more tolerable and avoids overforced valgus, eliminating the need for anesthetic blockade.

5. The technique is accessible and simple. In fact, there is no need to remove the roll from its wrapping.

Pediatric Hospital Medicine 2015's keynote speaker, Rita Mangione-Smith, MD, MPH, reviewed quality measures being developed for medically complex patients by the Center of Excellence on Quality of Care Measures for Children with Complex Needs (COE4CCN). As one of the most challenging groups to not only provide care but to determine if the management provided brings value, the importance of quality measures was emphasized.

Dr. Mangione-Smith, of Seattle Children’s Hospital, reviewed the need for quality measures, as well as the process of developing these measures. Quality measures help to quantify outcomes from care practices, stated Dr. Mangione-Smith, to compare similar settings, and also to set possible benchmarks. The processes range from identifying and prioritizing measures to how they are validated as true value added outcomes. Data sources, sample size, and reliability/validity of the measures are considered important components to ensure that answers or results acquired are applicable and relevant to the population. Another important component is to clearly define a child with medical complexity.

Some reasons why medically complex patients require this focus:

• The low amount of information about their quality of care, investment, and need for coordination;
• Lack of understanding of which care practices make the biggest differences on their outcomes; and
• Their high rate of resource utilization.

The objective was to see which areas of care, such as care coordination, have the highest benefit/improvement on outcomes so as to prioritize resources more effectively. Dr. Mangione-Smith also touched on some obstacles and challenges, such as lack of insurance coverage leading to use of emergency resources as their primary care and its effect on increasing resource utilization.

Measures were determined via a multi-component methodology. Surveys using a binary and linear mean scoring tool were used. This provided multiple types of information such as assessing family’s perception of care, their understanding of medical information and care plans, and their accessibility to medical care services or information about their child.

Currently there is very little evidence on which management methods have the most significant, or any, effect on children with medical complexity. The use of quality measures to help guide which practices may have the highest positive impact on their outcomes greatly adds to the challenging care of this population and can be “used to assess quality of care coordination over time.” TH

Many college students suffer from mental illness (Table 1),¹ which can have a negative impact on academic performance. Although psychotropic medications are an important part of treat­ment for many college students, the potential for misuse always is present. Drug misuse occurs when patients use medications for reasons inconsistent with legal or medical guidelines.² For example, patients may take a medica­tion that has not been prescribed for them or in a manner that is inconsis­tent with the prescriber’s instructions, including administration with other substances.³

Misuse of psychotropic drugs is prevalent among college students. A study of 14,175 students from 26 campuses reported that 14.7% of students taking a psychotropic are doing so without a prescription, including stimu­lants (52.6%), anxiolytics (38.4%), and antidepressants (17.4%).⁴ Another study states that more than one-third of responders reported misuse of >1 class of medication.⁵

Psychotropic misuse is concerning because it increases the risk of adverse events. Nearly one-half of medication errors are associated with writing and dispensing the prescription, which means that prescribers can work to reduce these errors.⁶ However, nonadherence, prescription misuse, and failure to disclose use of over-the-counter drugs, illicit drugs, and herbal products makes preventing most adverse events difficult, if not impossible, for prescribers.^7,8

Psychotropic drug misuse among college students is highly variable and unpredictable. Students misuse medications, including stimulants, ben­zodiazepines, and antidepressants, for a variety of reasons, such as study enhancement, experimentation, intoxication, self-medication, relaxation, and stress management.⁸ One survey reported that >70% of students taking a psychotropic medication took it with alcohol or another illicit drug.⁹

However, <20% of those using a psy­chotropic medication with alcohol or other illicit drugs told their health care provider(s),⁹ making it impossible for cli­nicians to predict a patient’s risk of drug− drug interactions and subsequent adverse events. Additionally, additive effects could occur¹⁰ and changes in a patient’s presenta­tion could be caused by a reaction to a com­bination of medications, rather than a new symptom of mental illness.

This article will examine common issues associated with drug misuse among col­lege-age students and review prevention strategies (Table 2).

Stimulants
Stimulants have the highest rate of diver­sion; 61.7% of college students prescribed stimulants have shared or sold their medi­cation.¹¹ A survey of 115 students from 2 universities reported that the most common reason for stimulant misuse was to enhance academic performance.¹² The same survey showed that some students take stimulants with Cannabis (17%) and alcohol (30%).¹² As a result, in addition to lowering grade point average (GPA) and other academic difficul­ties,¹³ students misusing stimulants are at risk of drug interactions.¹⁴

It is critical to ascertain the route of drug administration, because non-oral routes, including crushing then snorting or inject­ing, are associated with additional health concerns, such as accidental death or blood-borne illnesses.^15,16 Cardiac adverse effects of stimulants include hypertension, vasospasm, tachycardia, and dysrhythmia; psychiatric and other effects include sero­tonin syndrome, hallucinations, anxiety, paranoia, seizures, tics, hyperthermia, and tremor.¹⁷ Health care providers prescrib­ing or caring for people taking a stimulant should monitor for these potential effects.

The risk of switch to mania might not be apparent to those who prescribe stimulants or to young people who take non-prescribed stimulants for academic enhancement or to achieve medication-induced euphoria. Adolescent stimulant use is associated with symptoms of early-onset bipolar disorder in patients who have attention-deficit/ hyperactivity disorder (ADHD) and undi­agnosed bipolarity.¹⁸

The cardiovascular risk associated with stimulant use is debatable. Although sev­eral studies have been conducted,^19-21 meth­odological factors limit their applicability. To minimize potential risks, several precau­tions should be taken before prescribing a stimulant to treat ADHD.

First, obtain a detailed personal and family medical history, asking about pos­sible cardiovascular disease. Second, care­fully scrutinize the patient’s cardiovascular system during the physical exam. Third, consider additional testing, such as an elec­trocardiogram, if the patient’s history or physical exam indicates possible risk.²²

As a prescriber, you should be aware of the prevalence of stimulant use among students with and without ADHD, includ­ing those who could be feigning ADHD symptoms.¹⁵ Diversion could occur through sharing medications or selling them to friends and family.¹¹ It also is possible that these medications may be used with other illicit substances, such as Cannabis, ecstasy, cocaine, and opiates.²³ Students also could misuse stimulants by taking more than the prescribed dosage.²⁴

Risk factors for misuse of stimulants include: heavy alcohol use, previous illicit drug use, white race, fraternity or sorority membership, low GPA, increased hyperac­tivity symptoms, and attendance at a com­petitive college or university.^25-27

Benzodiazepines
Misuse of benzodiazepine is a significant component of prescription drug abuse and often occurs with other medications and alcohol.²⁸ Additional methods of mis­use include increased dosage and non-oral routes of administration.²⁹

A 2001 national survey reported that 7.8% of college students have misused benzodiaz­epines.²³ Common characteristics of benzo­diazepine abusers include young age, male sex, personality characteristics of impulsiv­ity and hopelessness, and abuse of other drugs, including cocaine and methadone.^28,29

Benzodiazepines are prescribed for their anxiolytic and hypnotic properties and stu­dents could use these drugs with other agents to augment the euphoric effects or diminish withdrawal symptoms.³⁰ Patients taking ben­zodiazepines for anxiety might self-medicate with alcohol, which increases sedation and depression, and can contribute to the risk for respiratory depression.¹⁰ Misuse of benzodi­azepines can result in cognitive and psycho­motor impairment and increase the risk of accidents and overdose.^29,31

Although overdose with monotherapy is rare, the risk increases when a benzodiaz­epine is used with alcohol¹⁰ or another respi­ratory depressants, such as opioids, because combination use can produce additive effects.²⁸ You should therefore avoid prescrib­ing benzodiazepines to patients who have a history of significant substance abuse and consider using alternative, non-addictive agents, such as selective serotonin reuptake inhibitors, or non-pharmaceutical treatment when such patients present with an anxiety disorder. The risk of adverse effects of ben­zodiazepines can be reduced by limiting the dosing and the duration of the treatment, and by using longer-acting rather than the more addictive, shorter-acting, agents.

Antidepressants
Health care providers should be aware that, despite the relative absence of physically addictive properties, antidepressants from most classes are abusable agents sought by young people for non-medical use. In particular, the literature highlights mono­amine oxidase inhibitors (MAOIs), tricyclic antidepressants, serotonin-norepinephrine reuptake inhibitors, and bupropion as the antidepressants most likely to be misused for their amphetamine-like euphoric effects or serotonin-induced dissociative effects.³² However, compared with other drug classes discussed in this article, the rate of antide­pressant misuse is relatively low among col­lege students.

Regardless of the antidepressant selected, clinicians should be concerned about alcohol use among college-age patients. Persons with depression are at increased risk of alcohol­ism compared with the general population.³³ This combination can increase depressive symptoms and sedation, and decrease coor­dination, judgment, and reaction time.³³

Excessive alcohol use can increase the risk of seizures in patients taking antidepressants such as buproprion.³⁴ Employ caution when prescribing bupropion to patients who have a predisposing clini­cal factor that increases seizure risk, such as excessive alcohol use and abrupt ces­sation, use of other medications that may lower seizure threshold (eg, theophylline, amphetamines, phenothiazines), and a his­tory of head trauma.³⁴

To minimize the risk of seizures with bupropion, titrate up the dosage slowly. Furthermore, using a low dosage during dual therapy for antidepressant augmenta­tion further decreases the risk of seizure.³⁵ For these reasons, we recommend that you avoid bupropion in patients who are at risk of binge drinking, and give careful consid­eration to providing alternative therapies for them.

Prescribers and patients should also keep in mind that hypertensive crisis could occur if MAOIs are combined with certain types of alcoholic beverages containing tyramine, including some wines and draft beer.³³

How you can identify and prevent misuse
Careful communication between health care provider and patient that is necessary to minimize the risk of adverse drug events with psychotropic medications often is lack­ing. For example, 24% of study college-age participants did not remember if their physi­cian provided a diagnosis and 28.8% could not recall being informed about side effects and, perhaps as a result, many students did not take their medications as prescribed.⁹

Further, prescribers should ask college-age patients who are undergoing stimulant treatment if they believe that they are being adequately treated. They should inquire about how they are taking their medica­tions.¹¹ These questions can lead to discus­sion of the need for these medications and reevaluation of their perceived indication.¹¹

Remind patients to take their medication only as directed.³⁶ Highlight the need to:
   • store medications in a discreet location
   • properly dispose of unused medications
   • keep tabs on the quantity of pills
   • know how to resist requests for diver­sion from peers.

The Substance Abuse and Mental Health Services Administration offers additional useful strategies,³⁷ and pharmacists also can be partners in substance use education and prevention.³⁸ These are examples of how health care providers can take an active role in providing patients with a thorough and detailed understanding of (1) their condi­tions and (2) their prescribed medications to improve efficacy and safety while pre­venting misuse.⁸

A study found that the most common method of obtaining these medications without a prescription is acquiring them from peers; 54% of undergraduate patients with stimulant prescriptions have been approached by peers to give, trade, or sell their drugs.²⁵ Other methods include pur­chasing medications online or faking pre­scriptions.³⁹ Health care providers should remind patients of the legal ramifications of sharing or selling their prescribed medi­cations. Finally, providers must be vigilant for students who may feign symptoms to obtain a prescription:
   • be wary if symptom presentation sounds too “textbook”
   • seek collateral history from family. Adults with ADHD should have shown symptoms during childhood
   • use external verification such as neuropsychological testing for ADHD. A neuropsychologist can detect deception by analyzing the pattern of responses to questions.

Patient assessment is a key step to in pre­venting abuse of psychotropic medications. Gentle inquiry about school-related stress and other risk factors for misuse can help practitioners determine if students are at risk of diversion and if additional screening is necessary.

In response to these issues, Stone and Merlo⁸ have suggested that, in addition to the educational programs held on col­lege campuses on alcohol, illicit drugs, and prescription painkillers, patients should be better informed on the appropriate use of prescription psychiatric medications, instructed to avoid sharing with family and friends, and assessed for abuse risk at regu­lar intervals.

To further protect patients from adverse outcomes during treatment, you can employ conservative and safe prescribing techniques. One strategy might be to keep a personal formulary that lists key medica­tions you use in everyday practice, includ­ing knowledge about each drug’s dosage, potential adverse effects, key warnings, and drug−drug interactions.⁴⁰

Furthermore, maintain healthy caution about newly approved medications and carefully consider how they measure up to existing agents—in other words, prac­tice evidence-based medicine, particu­larly when students request a particular agent.^40,41 Prescribers should evaluate the risk of abuse before prescribing and attempt to prevent misuse by limiting quantities and minimizing polypharmacy.

Last, pharmacists can be key allies for consultation and appropriate medication selection.

 
Bottom Line
Psychotropic medications are necessary to treat the variety of conditions—anxiety, attention-deficit/hyperactivity disorder, depression, and panic disorder—common among college students. However, students are at risk of combining their prescribed medications with other medications, drugs, and alcohol or could sell or share their medication with peers. Proper counseling and identification of risk factors can be important tools for preventing such events.

Many college students suffer from mental illness (Table 1),¹ which can have a negative impact on academic performance. Although psychotropic medications are an important part of treat­ment for many college students, the potential for misuse always is present. Drug misuse occurs when patients use medications for reasons inconsistent with legal or medical guidelines.² For example, patients may take a medica­tion that has not been prescribed for them or in a manner that is inconsis­tent with the prescriber’s instructions, including administration with other substances.³

Misuse of psychotropic drugs is prevalent among college students. A study of 14,175 students from 26 campuses reported that 14.7% of students taking a psychotropic are doing so without a prescription, including stimu­lants (52.6%), anxiolytics (38.4%), and antidepressants (17.4%).⁴ Another study states that more than one-third of responders reported misuse of >1 class of medication.⁵

Psychotropic misuse is concerning because it increases the risk of adverse events. Nearly one-half of medication errors are associated with writing and dispensing the prescription, which means that prescribers can work to reduce these errors.⁶ However, nonadherence, prescription misuse, and failure to disclose use of over-the-counter drugs, illicit drugs, and herbal products makes preventing most adverse events difficult, if not impossible, for prescribers.^7,8

Psychotropic drug misuse among college students is highly variable and unpredictable. Students misuse medications, including stimulants, ben­zodiazepines, and antidepressants, for a variety of reasons, such as study enhancement, experimentation, intoxication, self-medication, relaxation, and stress management.⁸ One survey reported that >70% of students taking a psychotropic medication took it with alcohol or another illicit drug.⁹

However, <20% of those using a psy­chotropic medication with alcohol or other illicit drugs told their health care provider(s),⁹ making it impossible for cli­nicians to predict a patient’s risk of drug− drug interactions and subsequent adverse events. Additionally, additive effects could occur¹⁰ and changes in a patient’s presenta­tion could be caused by a reaction to a com­bination of medications, rather than a new symptom of mental illness.

This article will examine common issues associated with drug misuse among col­lege-age students and review prevention strategies (Table 2).

Stimulants
Stimulants have the highest rate of diver­sion; 61.7% of college students prescribed stimulants have shared or sold their medi­cation.¹¹ A survey of 115 students from 2 universities reported that the most common reason for stimulant misuse was to enhance academic performance.¹² The same survey showed that some students take stimulants with Cannabis (17%) and alcohol (30%).¹² As a result, in addition to lowering grade point average (GPA) and other academic difficul­ties,¹³ students misusing stimulants are at risk of drug interactions.¹⁴

It is critical to ascertain the route of drug administration, because non-oral routes, including crushing then snorting or inject­ing, are associated with additional health concerns, such as accidental death or blood-borne illnesses.^15,16 Cardiac adverse effects of stimulants include hypertension, vasospasm, tachycardia, and dysrhythmia; psychiatric and other effects include sero­tonin syndrome, hallucinations, anxiety, paranoia, seizures, tics, hyperthermia, and tremor.¹⁷ Health care providers prescrib­ing or caring for people taking a stimulant should monitor for these potential effects.

The risk of switch to mania might not be apparent to those who prescribe stimulants or to young people who take non-prescribed stimulants for academic enhancement or to achieve medication-induced euphoria. Adolescent stimulant use is associated with symptoms of early-onset bipolar disorder in patients who have attention-deficit/ hyperactivity disorder (ADHD) and undi­agnosed bipolarity.¹⁸

The cardiovascular risk associated with stimulant use is debatable. Although sev­eral studies have been conducted,^19-21 meth­odological factors limit their applicability. To minimize potential risks, several precau­tions should be taken before prescribing a stimulant to treat ADHD.

First, obtain a detailed personal and family medical history, asking about pos­sible cardiovascular disease. Second, care­fully scrutinize the patient’s cardiovascular system during the physical exam. Third, consider additional testing, such as an elec­trocardiogram, if the patient’s history or physical exam indicates possible risk.²²

As a prescriber, you should be aware of the prevalence of stimulant use among students with and without ADHD, includ­ing those who could be feigning ADHD symptoms.¹⁵ Diversion could occur through sharing medications or selling them to friends and family.¹¹ It also is possible that these medications may be used with other illicit substances, such as Cannabis, ecstasy, cocaine, and opiates.²³ Students also could misuse stimulants by taking more than the prescribed dosage.²⁴

For patients with follicular lymphoma treated with a rituximab-based combination chemotherapy regimen, early disease progression is associated with significantly worse overall survival, suggesting the need for additional interventions, according to results of a multicenter study.

Among 588 patients with stage 2-4 follicular lymphoma treated with first-line R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone) and followed for a median of 7 years in the National LymphoCare Study, overall survival (OS) at 2 years was 68% for those who had disease progression within 2 years, compared with 97% for patients with no disease progression during that time.

Similarly, 5-year overall survival was 50% for patients with early progression of disease, compared with 90% for patients with no early progression, write Dr. Carla Casulo of the University of Rochester (N.Y.) Medical Center and colleagues. The study is in anearly online publication in the Journal of Clinical Oncology.

“Given our findings, early relapse after diagnosis in patients treated with first-line chemoimmunotherapy is a powerful prognostic indicator of outcome and should be used to stratify the risk of patients in studies of relapsed follicular lymphoma,” the authors wrote.

The findings were validated in an independent cohort of patients with follicular lymphoma treated with R-CHOP from the University of Iowa and Mayo Clinical Molecular Epidemiology Resource, and are consistent with findings from other studies of patients treated with different rituximab-based regimens, the investigators reported.

In unadjusted analysis, early disease progression was associated with a hazard ratio (HR) of 7.17 (95% confidence interval [CI] 4.83-10.65); the effect remained after adjustment for the Follicular Lymphoma International Prognostic Index (FLIPI) score (HR 6.44, 95% CI, 4.33-9.58).

Factors associated with early progression included age, Eastern Cooperative Oncology Group performance score, nodal sites, and disease stage.

Early use of aggressive salvage therapies or autologous stem-cell transplantation could improve outcomes in patients with early disease progression, the authors wrote. However, only 8 patients among the 110 with early progression went on to transplant, not a large enough sample for meaningful analysis, they added.

“This newly defined high-risk group of patients represents a distinct population in whom further study is warranted in both directed prospective clinical trials of follicular lymphoma biology and treatment. Moreover, we propose that 2-year progression-free survival may be a practical and meaningful clinical end point for trials involving a chemoimmunotherapy backbone,” they concluded.

For patients with follicular lymphoma treated with a rituximab-based combination chemotherapy regimen, early disease progression is associated with significantly worse overall survival, suggesting the need for additional interventions, according to results of a multicenter study.

Among 588 patients with stage 2-4 follicular lymphoma treated with first-line R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone) and followed for a median of 7 years in the National LymphoCare Study, overall survival (OS) at 2 years was 68% for those who had disease progression within 2 years, compared with 97% for patients with no disease progression during that time.

Similarly, 5-year overall survival was 50% for patients with early progression of disease, compared with 90% for patients with no early progression, write Dr. Carla Casulo of the University of Rochester (N.Y.) Medical Center and colleagues. The study is in anearly online publication in the Journal of Clinical Oncology.

Little is known about people who write to criminals incar­cerated for a violent crime. However, existence of Web sites such as WriteAPrisoner.com, Meet-An-Inmate.com, and PrisonPenPals.com suggests some appetite among the public for corresponding with the incarcerated. Writers of letters might be drawn to the “bad boy” image of prison­ers. Furthermore, much has been written of the willingness of some battered women to remain in an abusive domestic relationship, leading them to correspond with their abusers even after those abusers are incarcerated.^1,2

To our knowledge, no examination of letters written to a mass murderer has been published. Therefore, we catego­rized and analyzed 784 letters sent to a high-profile male mass murderer whose crime was committed during the past decade. Here is a description of the study and what we found, as well as discussion of how our findings might offer utility in a psychiatric practice.

Goals of the study
We hypothesized that a large percentage of those letters could be classified as “Romantic,” given the lay percep­tion that it is women who write to mass murderers. We also sought to evaluate follow-up letters sent by these writers to test the assumption that their individual goals would be con­stant over time.

We performed this study in the hope that the research could assist psychiatric practitioners in treating patients who seek to associate with a violent person (see “Treatment considerations,”). We thought it might be helpful for practitioners to get a better understanding of the nature of people who write to a violent offender or express a desire to do so.

Methods of study
Two authors (R.S.J. and D.P.G.) evaluated 819 letters that had been written by non-incarcerated, non-family adults to 1 mass murderer. The initial letter and follow-up letters written by each unique writer (n = 333) were categorized as follows:
   • state or country from which the letter was sent
   • age
   • sex
   • number of letters sent by each writer
   • whether a photograph was enclosed
   • whether additional items were enclosed (eg, gifts, drawings)
   • whether the letter was rejected by prison authorities
   • the writer’s purpose.

The study was approved by the insti­tutional review board of Baylor College of Medicine.

Letters were assigned to 1 of 5 categories:

Acquaintance letters sought ongoing cor­respondence relationship with the murderer. They focused largely on conveying informa­tion about the writer.

Show of support letters also sought an ongoing correspondence relationship with the murderer, but instead focused on him, not the writer.

Romance letters used words that conveyed romantic or non-platonic affection.

Spiritual letters gave advice to the mur­derer with a religious tone.

Words of wisdom letters offered advice but lacked a religious tone.

Given the nonstandardized nature of categorization and the lack of a formal questionnaire, we were unable to perform an exploratory factor analysis on our cat­egorizations. Inter-rater reliability of letter categorization was 0.79.

Results: Writer profiles, purpose for writing
In all, we reviewed 819 letters:
   • Thirty-five letters were excluded because they were written by family mem­bers, children, or other prisoners
   • Of the remaining 784 letters, there were 333 unique writers
   • Two-hundred sixty letters were writ­ten by women, 61 by men; 2 were co-written by both sexes; sex could not be determined for 10.

Women were more likely than men to write a letter (P = .014) and to write ≥3 letters (P = .001). The age of the writer was deter­mined for 117 (35.1%) letters; mean age was 27.8 (± 8.9) years (range, 18 to 59 years).

The purpose of the letters differed by sex (P < .001) but not by the writer’s age (P = .058). Women were more likely than men to write letters categorized as “Acquaintance,” “Romance,” and “Show of support”; in con­trast, men were more likely than women to write a letter categorized as “Spiritual”  (Table 1). Approximately 95% of let­ters were handwritten. Letters averaged 3 pages (range, 1 to 16 pages).

Two-hundred sixteen writers wrote a single letter; 53 wrote 2 letters; 18 wrote 3 let­ters; 11 wrote 4 letters; 30 wrote 5 to 10 let­ters; and 9 wrote 11 to 43 letters. The purpose of follow-up letters was associated with the age of the writer (P < .001) and with the writ­er’s sex (P < .001). Women were more likely to write “Show of support” and “Romance” follow-up letters; men were more likely to write “Spiritual” follow-up letters (Table 2).

Results suggested that the purpose of the initial letter was a reasonable predictor of the purpose of follow-up letters (P < .001) (Table 3). The murderer never responded to any letters. Letters were most often writ­ten from his state of incarceration; next, from contiguous states; then, from non-contiguous states; and, last, from interna­tional locations (P < .001).

Of the initial letters from writers who wrote ≥10, 60% were categorized as “Acquaintance” and 20% as “Romance.” The writer who wrote the most letters (43) moved during the course of her letter-writing to live in the same state as the murderer; she stated in her letters that she did so to be closer to him and to be able to attend his court hearings. Four other writers, each of whom wrote >5 letters, stated that they had traveled to the murderer’s state of incarcera­tion to attend some of his hearings in person.

Acquaintance. Hi, Steve. I’ve been follow­ing your case and just wanted to write you so that maybe we could be friends or keep in touch since you’re probably pretty bored. I’m a 27-year-old college student studying market­ing and working at Applebee’s as a waitress (for now) until I can land my dream job. I’ve enclosed a picture of me and my dachshund along with a photo of my favorite beach in the world. Write me back if you want. Jenny.

Show of support. Steve: I’ve been really wor­ried about you since first seeing you on TV. You look different lately and I hope they’re treating you OK and feeding you decent food. In case they’re not, I’ve enclosed a little something to buy yourself a treat. Just know that there are many of us that care about you and are really pulling for you to be strong in this tough situ­ation you’re in. Yours truly, Karen.

Romance. Dearest Steven: My mind has been filled with thoughts of you and of us since I last saw you in my dreams! Be strong, because you are going to beat this once they understand that you are not responsible for what happened! Don’t you see, sweetie, the system failed you, and now you’re caught up in something that you will soon overcome. When I think of the day that you get released, and how we’ll be able to settle down some­where together, it gets me incredibly excited. You and I are meant to be together, because I understand you and can help you get better. I love you, Steven! Please write me back so that I know we’re on the same page about our plans for the future. Love, ♥ Your sweetie, Rachel.

Spiritual. Dear Child of God: The Lord has a plan for you. I know that things right now might be confusing, and you’re in a black place, but He is there right beside you. If you need some reading materials to give you com­fort, just let me know and I can get a Bible to you along with some other books to give you solace and strengthen your walk with Him. God forgives you and he loves you so much! Much love in Christ, Mary.

Discussion
Given that the mass murderer in this study was a young man, it is not surpris­ing that 78% of writers of initial letters were women. However, it is interesting that, among women’s initial letters, 44% were “Acquaintance” letters and only 15% were categorized as “Romance.”

Given the severity of the murderer’s crime, it is remarkable that he received only 1 “Hate mail” letter.

Initial “Spiritual” letters were more likely to be followed by letters of the same category than any other category; “Romance” letters were a close second. This demonstrates the consistent efforts of writers in these 2 categories. Highly persis­tent writers (≥10 letters) were most likely to fall into “Acquaintance” and “Romance” categories. The persistence of these writers is remarkable, in view of the fact that none of their letters were answered. We hypoth­esize that the killer did not reply because he had no interest in correspondence.

Similarities to stalking. Given that 9 writ­ers wrote >10 letters each and 2 wrote >20 each, elements of their behavior are not unlike what is seen in stalkers.³ Consistent with the stalking literature and Mullen et al4 stalker typology, many writers in this study appeared to seek intimacy with the perpetrator through “Romance” or “Show of support” letters, and might be akin to Mullen’s so-called intimacy-seeking stalker. Such stalkers’ behavior arises out of loneliness, with a strong desire for a rela­tionship with the target; a significant per­centage of such stalkers suffer a delusional disorder.

Mullen’s so-called incompetent suitor stalker is similar to the intimacy-seeking type but, instead, has an interest in a short-term relationship and is far less persistent in his (her) stalking behavior⁴; this type might apply to the writers in this study who wrote >1 but <10 letters.

Two additional observations also are notable when trying to characterize people who write letters: (1) A high percentage of people who stalk a celebrity suffer a psy­chotic disorder^5,6; (2) 4 letter-writers trav­eled, and 1 relocated, to the murderer’s state of incarceration to attend his hearings and be closer to him.

This study has limitations:
   • categorization of letters is inherently subjective and the categories themselves were created by the researchers
   • the nature and categorization of such letters might vary considerably with the age and sex of the violent criminal; our findings in this case are not generalizable.

Last, researchers who plan to study writers of letters to incarcerated criminals should consider sending a personality test and other questionnaires to those writers to understand this population better.

Treatment considerations
Psychiatrists treating patients who seek a romantic attachment with a violent person should consider psychotherapy as a means of treating possible character pathology. The desire for romance with a violent crimi­nal was greater among repeat writers (20%) than in initial letters (15%), suggesting that people who have a strong inclination to associate with a violent person might benefit from exploring romantic feelings in therapy. Specifically, therapists would be wise to explore with such patients the possibility that they experienced violence or verbal abuse in childhood or adulthood.

To the extent that evidence of prior abuse exists, a diagnosis of posttraumatic stress disorder (PTSD) might be appro­priate; specialized therapy for men and women with a history of abuse might be indicated. It is important to provide vali­dation for patients who are victims when they describe their abuse, and to stress that they did nothing to provoke the violence. Furthermore, investigation of why the patient feels drawn romantically toward a violent criminal is helpful, as well as an examination of how such behavior is self-defeating.

There might be value in having patients keep a journal in lieu of actually sending letters; there is evidence that “journaling” can reduce substance use recidivism.⁷ This work can be performed in conjunction with group or individual psychotherapy that addresses any history of abuse and subse­quent PTSD.

Many patients are reluctant to discuss their romantic feelings toward a violent criminal until the psychiatrist has estab­lished a strong doctor−patient relationship. Last, clinicians should not hesitate to refer these patients to a therapist who specializes in domestic violence.

   • Two-hundred sixty letters were writ­ten by women, 61 by men; 2 were co-written by both sexes; sex could not be determined for 10.

Women were more likely than men to write a letter (P = .014) and to write ≥3 letters (P = .001). The age of the writer was deter­mined for 117 (35.1%) letters; mean age was 27.8 (± 8.9) years (range, 18 to 59 years).

The purpose of the letters differed by sex (P < .001) but not by the writer’s age (P = .058). Women were more likely than men to write letters categorized as “Acquaintance,” “Romance,” and “Show of support”; in con­trast, men were more likely than women to write a letter categorized as “Spiritual”  (Table 1). Approximately 95% of let­ters were handwritten. Letters averaged 3 pages (range, 1 to 16 pages).

Two-hundred sixteen writers wrote a single letter; 53 wrote 2 letters; 18 wrote 3 let­ters; 11 wrote 4 letters; 30 wrote 5 to 10 let­ters; and 9 wrote 11 to 43 letters. The purpose of follow-up letters was associated with the age of the writer (P < .001) and with the writ­er’s sex (P < .001). Women were more likely to write “Show of support” and “Romance” follow-up letters; men were more likely to write “Spiritual” follow-up letters (Table 2).

Results suggested that the purpose of the initial letter was a reasonable predictor of the purpose of follow-up letters (P < .001) (Table 3). The murderer never responded to any letters. Letters were most often writ­ten from his state of incarceration; next, from contiguous states; then, from non-contiguous states; and, last, from interna­tional locations (P < .001).

Of the initial letters from writers who wrote ≥10, 60% were categorized as “Acquaintance” and 20% as “Romance.” The writer who wrote the most letters (43) moved during the course of her letter-writing to live in the same state as the murderer; she stated in her letters that she did so to be closer to him and to be able to attend his court hearings. Four other writers, each of whom wrote >5 letters, stated that they had traveled to the murderer’s state of incarcera­tion to attend some of his hearings in person.

Acquaintance. Hi, Steve. I’ve been follow­ing your case and just wanted to write you so that maybe we could be friends or keep in touch since you’re probably pretty bored. I’m a 27-year-old college student studying market­ing and working at Applebee’s as a waitress (for now) until I can land my dream job. I’ve enclosed a picture of me and my dachshund along with a photo of my favorite beach in the world. Write me back if you want. Jenny.

Show of support. Steve: I’ve been really wor­ried about you since first seeing you on TV. You look different lately and I hope they’re treating you OK and feeding you decent food. In case they’re not, I’ve enclosed a little something to buy yourself a treat. Just know that there are many of us that care about you and are really pulling for you to be strong in this tough situ­ation you’re in. Yours truly, Karen.

Romance. Dearest Steven: My mind has been filled with thoughts of you and of us since I last saw you in my dreams! Be strong, because you are going to beat this once they understand that you are not responsible for what happened! Don’t you see, sweetie, the system failed you, and now you’re caught up in something that you will soon overcome. When I think of the day that you get released, and how we’ll be able to settle down some­where together, it gets me incredibly excited. You and I are meant to be together, because I understand you and can help you get better. I love you, Steven! Please write me back so that I know we’re on the same page about our plans for the future. Love, ♥ Your sweetie, Rachel.

Spiritual. Dear Child of God: The Lord has a plan for you. I know that things right now might be confusing, and you’re in a black place, but He is there right beside you. If you need some reading materials to give you com­fort, just let me know and I can get a Bible to you along with some other books to give you solace and strengthen your walk with Him. God forgives you and he loves you so much! Much love in Christ, Mary.

Discussion
Given that the mass murderer in this study was a young man, it is not surpris­ing that 78% of writers of initial letters were women. However, it is interesting that, among women’s initial letters, 44% were “Acquaintance” letters and only 15% were categorized as “Romance.”

Given the severity of the murderer’s crime, it is remarkable that he received only 1 “Hate mail” letter.

Initial “Spiritual” letters were more likely to be followed by letters of the same category than any other category; “Romance” letters were a close second. This demonstrates the consistent efforts of writers in these 2 categories. Highly persis­tent writers (≥10 letters) were most likely to fall into “Acquaintance” and “Romance” categories. The persistence of these writers is remarkable, in view of the fact that none of their letters were answered. We hypoth­esize that the killer did not reply because he had no interest in correspondence.

Similarities to stalking. Given that 9 writ­ers wrote >10 letters each and 2 wrote >20 each, elements of their behavior are not unlike what is seen in stalkers.³ Consistent with the stalking literature and Mullen et al4 stalker typology, many writers in this study appeared to seek intimacy with the perpetrator through “Romance” or “Show of support” letters, and might be akin to Mullen’s so-called intimacy-seeking stalker. Such stalkers’ behavior arises out of loneliness, with a strong desire for a rela­tionship with the target; a significant per­centage of such stalkers suffer a delusional disorder.

Mullen’s so-called incompetent suitor stalker is similar to the intimacy-seeking type but, instead, has an interest in a short-term relationship and is far less persistent in his (her) stalking behavior⁴; this type might apply to the writers in this study who wrote >1 but <10 letters.

Two additional observations also are notable when trying to characterize people who write letters: (1) A high percentage of people who stalk a celebrity suffer a psy­chotic disorder^5,6; (2) 4 letter-writers trav­eled, and 1 relocated, to the murderer’s state of incarceration to attend his hearings and be closer to him.

This study has limitations:
   • categorization of letters is inherently subjective and the categories themselves were created by the researchers
   • the nature and categorization of such letters might vary considerably with the age and sex of the violent criminal; our findings in this case are not generalizable.

Last, researchers who plan to study writers of letters to incarcerated criminals should consider sending a personality test and other questionnaires to those writers to understand this population better.

Treatment considerations
Psychiatrists treating patients who seek a romantic attachment with a violent person should consider psychotherapy as a means of treating possible character pathology. The desire for romance with a violent crimi­nal was greater among repeat writers (20%) than in initial letters (15%), suggesting that people who have a strong inclination to associate with a violent person might benefit from exploring romantic feelings in therapy. Specifically, therapists would be wise to explore with such patients the possibility that they experienced violence or verbal abuse in childhood or adulthood.

To the extent that evidence of prior abuse exists, a diagnosis of posttraumatic stress disorder (PTSD) might be appro­priate; specialized therapy for men and women with a history of abuse might be indicated. It is important to provide vali­dation for patients who are victims when they describe their abuse, and to stress that they did nothing to provoke the violence. Furthermore, investigation of why the patient feels drawn romantically toward a violent criminal is helpful, as well as an examination of how such behavior is self-defeating.

There might be value in having patients keep a journal in lieu of actually sending letters; there is evidence that “journaling” can reduce substance use recidivism.⁷ This work can be performed in conjunction with group or individual psychotherapy that addresses any history of abuse and subse­quent PTSD.

Many patients are reluctant to discuss their romantic feelings toward a violent criminal until the psychiatrist has estab­lished a strong doctor−patient relationship. Last, clinicians should not hesitate to refer these patients to a therapist who specializes in domestic violence.

The protein tetraspanin3 (Tspan3) plays a critical role in the development and progression of acute myeloid leukemia (AML), according to research published in Cell Stem Cell.

Investigators found that Tspan3, a cell surface molecule, is expressed in hematopoietic stem and progenitor cells as well as in leukemic cells.

Deleting Tspan3 did not affect normal hematopoiesis, but it prevented AML self-renewal and propagation in vitro and in vivo.

Inhibiting Tspan3 in patient samples led to decreased colony formation in vitro and hindered leukemic growth in primary patient-derived xenografts.

“We found that blocking this molecule leads to a very profound inhibition of leukemia growth,” said study author Tannishtha Reya, PhD, of the University of California San Diego in La Jolla.

These findings build on earlier work by Dr Reya and her colleagues, in which they identified the RNA binding protein Musashi 2 (Msi2) as a critical stem cell signal that is hijacked in several hematologic malignancies.

“We had this idea that analysis of the molecular programs controlled by Musashi 2 may identify new genes important for these leukemias,” Dr Reya said.

So the investigators conducted a genome-wide expression analysis of Msi2-deficient cancer stem cells from blast-crisis chronic myelogenous leukemia and AML. This revealed genes commonly regulated by Msi2 in both leukemias.

Tspan3 was one of the core genes controlled by Msi2. The Tspan3 protein is part of a large family of membrane proteins (the tetraspanin family) that are active in diverse cellular processes, including cell adhesion and proliferation, hematopoietic stem cell function, and blood formation.

“We are particularly excited about this work because, to our knowledge, this is the first demonstration of a requirement for Tspan3 in any primary cancer,” Dr Reya said.

To explore the connection further, the investigators generated the first Tspan3 knockout mouse. In testing, the team found that Tspan3 deletion impaired leukemia stem cell self-renewal and disease propagation and markedly improved survival in the mice.

In patient samples, Tspan3 inhibition blocked the growth of AML, which suggests Tspan3 is also important in human disease.

Dr Reya said these findings are particularly important because AML often doesn’t respond to current therapies. And because Tspan3 is a surface molecule, it is of great translational interest as a target for antibody-mediated therapy.

“There’s been great progress in pediatric leukemia research and treatment over the last few years,” Dr Reya said. “But unfortunately, children with acute myeloid leukemia are often poor responders to current treatments. So identifying new approaches to target this disease remains critically important.”

Oncogenesis does not depend only on the accumulation of mutations but on evolutionary pressures acting on cell populations, according to a paper published in PNAS.

The authors say the ecosystem of a healthy tissue landscape lets healthy cells outcompete cells with cancerous mutations.

It is when the tissue ecosystem changes due to aging, smoking, or other stressors that cells with cancerous mutations can suddenly find themselves the most fit.

And this allows the cell population to expand over generations of natural selection.

This model of oncogenesis has profound implications for cancer therapy and drug design, according to the authors.

“We’ve been trying to make drugs that target mutations in cancer cells,” said author James DeGregori, PhD, of University of Colorado School of Medicine in Aurora.

“But if it’s the ecosystem of the body, and not only cancer-causing mutations, that allows the growth of cancer, we should also be prioritizing interventions and lifestyle choices that promote the fitness of healthy cells in order to suppress the emergence of cancer.”

The proposed model helps to answer a long-standing question known as Peto’s Paradox. If cancer is due to random activating mutation, larger animals with more cells should be at greater risk of developing cancer earlier in their lives. Why then do mammals of vastly different sizes and lifespans all seem to develop cancer mostly late in life?

“Blue whales have more than a million times more cells and live about 50 times longer than a mouse, but the whale has no more risk than a mouse of developing cancer over its lifespan,” Dr DeGregori noted.

The answer he and colleague Andrii Rozhok, PhD, propose is that, in addition to activating mutations, cancer may require age-associated changes to the tissue landscape in order for evolution to favor the survival and growth of cancer cells over the competition of healthy cells.

“Healthy cells are optimized for the ecosystem of the healthy body,” Dr DeGregori said. “But when the tissue ecosystem changes, such as with aging or smoking, cancer-causing mutations are often very good at exploiting the conditions of a damaged tissue landscape.”

This model is supported by studies showing that mutations that can cause cancer do not necessarily increase a cell’s fitness.

“In fact, healthy cells are so optimized to the healthy tissue landscape that almost any mutation makes them less fit,” Dr DeGregori said.

For example, some cancer cells mutate in a way that allows them to survive in the oxygen-poor tissue environments found in the center of developing tumors. But this adaptation only confers a fitness benefit in oxygen-poor tissues.

In a healthy, oxygen-rich tissue, this mutation would not confer this advantage. In healthy tissue, cells with this mutation lose the evolutionary race to the healthy cells. Cancer cells are outcompeted and die, or, at least, their population is held in check and remains insignificantly small.

But what happens when the tissue landscape changes?

“When the body changes due to aging, smoking, inherited genetic differences, or other factors, it changes the tissue ecosystem, allowing a new kind of cell to replace the healthy ones,” Dr DeGregori said.

Certainly, cancer development requires mutations and other genetic alterations. But how do these mutations cause cancer?

It may not be that these mutations create accidental “super cells” that immediately run amok. Instead, it may be that oncogenic mutations are often or always present in the body but are kept at bay by selection pressures set against them.

That is, until the tissue ecosystem and its pressures change in ways that make cells with cancerous mutations more likely to survive than healthy cells. Over time, this allows the population of cancer cells to overcome that of healthy cells.

People can avoid some of these tissue changes by lifestyle choices, Dr DeGregori noted, but aging cannot be stopped. Still, there may be features of the tissue landscape that, with new therapies and new understanding, could be reinforced in ways to resist cancer better for longer.

Researchers say they have uncovered a new avenue for therapeutic intervention in thrombotic thrombocytopenic purpura (TTP).

The team discovered how autoimmune antibodies in a TTP patient recognize and bind to ADAMTS13.

They believe this knowledge could help them alter ADAMTS13 to produce a therapeutic enzyme that can elude recognition by autoimmune antibodies yet still retain its ability to cleave von Willebrand factor.

Such an enzyme could be given to TTP patients in the hospital to speed recovery and cut the cost of treatment.

Long Zheng, MD, PhD, of the University of Alabama at Birmingham, and his colleagues described this work in PNAS.

The researchers found that 5 small loops in ADAMTS13’s amino acid sequence are necessary for autoantibodies to bind to ADAMTS13.

Cutting or substituting several amino acids out of any of the 5 loops prevented binding. Small deletions in a loop also left the enzyme unable to cleave von Willebrand factor.

“This was really surprising,” Dr Zheng said. “It’s like a table with 5 legs. If you take 1 away, it should still stand, but, somehow, it collapsed. This suggests that you need the coordinated activity of all 5.”

Thus, it appears that the autoimmune antibodies in TTP patients inhibit the enzyme by physically blocking the recognition site of ADAMTS13 for von Willebrand factor.

Analyses of autoantibodies from 23 more TTP patients revealed that most use the same binding site. This suggests modifying the ADAMTS13 enzyme by protein engineering may be able to help a wide range of TTP patients.

Details of the research

Dr Zheng and his colleagues first isolated messenger RNAs that code single chains of variable regions of monoclonal antibodies from B cells collected from patients with acquired TTP.

The team used phage display to select the messenger RNAs that code specific antibodies that bind and inhibit ADAMTS13. These monoclonal antibodies were then expressed in E coli cells, purified, and biochemically characterized.

Three inhibitory monoclonal antibodies were selected for further study by hydrogen-deuterium exchange coupled with mass spectrometry. This technology uses amine hydrogen exchange with deuterium on each amino acid residue except proline.

After the reaction was stopped, the protein was cut into small pieces (or peptide fragments) and run through high-performance liquid chromatography for separation and mass spectrometry for identification.

Antibody binding sites were detected by their ability to block the hydrogen and deuterium exchange, as compared with ADAMTS13 that was unbound.

One of the 3 high-affinity probes selected by phage display was used for the competition experiments against polyclonal autoimmune antibodies from 23 TTP patients.

The results show that this particular binding epitope is common among patients with acquired autoimmune TTP.

The team used phage display to select the messenger RNAs that code specific antibodies that bind and inhibit ADAMTS13. These monoclonal antibodies were then expressed in E coli cells, purified, and biochemically characterized.

Three inhibitory monoclonal antibodies were selected for further study by hydrogen-deuterium exchange coupled with mass spectrometry. This technology uses amine hydrogen exchange with deuterium on each amino acid residue except proline.

After the reaction was stopped, the protein was cut into small pieces (or peptide fragments) and run through high-performance liquid chromatography for separation and mass spectrometry for identification.

Antibody binding sites were detected by their ability to block the hydrogen and deuterium exchange, as compared with ADAMTS13 that was unbound.

One of the 3 high-affinity probes selected by phage display was used for the competition experiments against polyclonal autoimmune antibodies from 23 TTP patients.

The results show that this particular binding epitope is common among patients with acquired autoimmune TTP.

Charles M. Rubin, MD, an associate professor of pediatrics at the University of Chicago Medicine, has passed away at the age of 62.

Dr Rubin died while at work on July 17.

He had just arrived at the pediatric clinic at the University of Chicago Medicine Comprehensive Cancer Center at Silver Cross Hospital in New Lenox when his heart stopped.

Resuscitation efforts were unsuccessful.

An authority on pediatric cancers, Dr Rubin had a particular interest in brain tumors and cancer occurring in children with genetic syndromes. He combined experience in basic laboratory research on the genetics of cancer with broad clinical expertise.

“I can’t put into words how much I respected him,” said colleague Tara Henderson, MD, associate professor of pediatrics and director of the Childhood Cancer Survivors Center at the University of Chicago’s Comer Children’s Hospital.

“He was amazingly knowledgeable, compassionate, and thoughtful—traits at the core of our program. I take his influence with me as I care for my patients. He could also be funny, with a dry, quiet sense of humor. We never knew when it was coming. We miss him dearly.”

Dr Rubin was born February 10, 1953, in Long Branch, New Jersey. He earned his bachelor’s degree from the University of Pennsylvania in 1975 and his medical degree from Tufts University School of Medicine in 1979.

Dr Rubin completed his pediatric residency at the Children’s Hospital of Philadelphia in 1982, followed by a fellowship in pediatric hematology/oncology at the University of Minnesota in 1985.

He went to the University of Chicago in 1985 as a cytogenetics and molecular biology fellow in the laboratory of Janet Rowley, MD, an internationally recognized pioneer in understanding the genetics of cancer.

Dr Rubin joined the faculty as an assistant professor of pediatrics and medicine and a member of the university’s Cancer Research Center in 1987. In 1991, he and adult oncologist Funmi Olopade, MD, co-founded the university’s Cancer Risk Clinic.

“Chuck Rubin was one of the finest individuals I have ever known,” said Michelle Le Beau, PhD, a former colleague in the Rowley laboratory and now director of the University of Chicago Medicine Comprehensive Cancer Center.

“He was a consummate academician and physician who blended compassion and sensitivity with brilliant clinical acumen. His dedication to his family, his patients, and the University of Chicago was selfless and unparalleled. It was a privilege to work with him and an honor to learn from his example.”

Although Dr Rubin continued to work closely with his basic-science colleagues, contributing to more than 50 original reports in academic journals, his interests increasingly focused on patient care.

At the same time, he took on several administrative roles. He served as course director for pediatric grand rounds and the medical center’s pediatric tumor board.

He directed the pediatric hematology/oncology fellowship for 7 years and the pediatric neuro-oncology program for 10 years. He also volunteered for medical staff positions in various educational and rehabilitative summer camps for children with cancer.

Dr Rubin was a leader in the University of Chicago Medicine’s efforts to take a research-driven approach to pediatric cancer care into the community, serving as director of pediatric hematology/oncology outreach since 2008.

Dr Rubin is survived by his wife, Gretchen; their 4 daughters, Elizabeth, Jane, Lucy, and Claire; brothers Michael, Peter, and Richard; and many nieces and nephews.

Among patients with refractory anemia with ring sideroblasts, the presence of a common mutation in SF3B1 appears to be a marker for an indolent clinical course and favorable outcome compared to patients with wild-type SF3B1, European investigators reported.

The gene SF3B1, which encodes for a splicing factor subunit, is frequently mutated in cases of chronic lymphocytic leukemia and myelodysplastic syndromes.

“SF3B1 mutation is a major determinant of disease phenotype and clinical outcome in MDS [myelodysplastic syndrome] with ring sideroblasts. SF3B1-mutated MDS is characterized by homogeneous hematologic features, favorable prognosis, and restricted patterns of co-mutated genes and clonal evolution. Overall, these results strongly support the recognition of MDS associated with SF3B1 mutation as a distinct MDS subtype. Conversely, SF3B1-negative MDS with ring sideroblasts represents a subset with a high prevalence of TP53 mutations and worse outcome that should be taken into consideration in clinical decision-making,” the study authors conclude.

Dr. Luca Malcovati and his colleagues from the University of Pavia, Italy, and other European centers, conducted a mutational analysis of 293 patients with myeloid neoplasms and 1% or more ring sideroblasts. They found somatic mutations in SF3B1 in 129 of 159 patients with refractory anemia with ring sideroblasts (RARS) or refractory cytopenia with multilineage dysplasia and ring sideroblasts (RCMD-RS). In contrast, there was a significantly lower prevalence of SF3B1 mutations among 50 patients with myelodysplastic/myeloproliferative neoplasm (MDS/MPN), and among 84 additional patients with other myeloid diseases under the World Health Organization classification of disorders of hematopoietic and lymphoid tissues (P < .001).

In multivariable analyses controlling for demographic and disease-related factors, patients with SF3B1 mutations had significantly better overall survival (hazard ratio, 0.37; P = .003), as well as a lower cumulative incidence of disease progression (HR, 0.31; P = .018), compared with patients with wild-type SF3B1 (Blood 2015;126[2]:233-41).

Mutations in SF3B1 were predictive of better outcomes among patients with RARS, RCMD-RS, and in patients with MDS without excess blasts.

When they looked at other mutations, the investigators found that in patients with SF3B1 mutations, the mutations in DNA methylation genes were associated with the presence of multilineage dysplasia, but this association had no significant effect on clinical outcomes.

Among patients with wild-type SB3B1, mutations in TP53 were frequently seen, and these mutations were associated with poor outcomes.
