This report describes a 15 1/2 year old white male with twenty-nail dystrophy who has had recurrent episodes of immune thrombocytopenic purpura, autoimmune hemolytic anemia, and mild depression of immunoglobulin levels. The concurrence of these events suggests that each shares a common pathophysiologic mechanism, possibly an autoimmune process.

Article abstract-Interferon beta (IFNbeta) reduces the relapse rate, disease activity as measured by serial MRI scanning, and disease progression of MS. Therapy with IFNbeta may be associated with a number of adverse reactions. Relatively frequent side effects include flu-like symptoms, transient laboratory abnormalities, menstrual disorders, and increased spasticity. Dermal injection site reactions occur after subcutaneous application of IFNbeta-1b and IFNbeta-1a. Possible side effects of IFNbeta include various autoimmune reactions, capillary leak syndrome, anaphylactic shock, thrombotic-thrombocytopenic purpura, insomnia, headache, alopecia, and depression. We discuss the mechanisms and management of the different side effects of IFNbeta.

Interferons are proteins produced by human blood cells in response to stimulation (viral infection). The natural roles of interferons are host defense and modulation of the immune system. Therapeutic uses are based on these roles. Interferon-alpha has been widely used for malignancies, skin conditions, viral infections, and myeloproliferative disorders. Interferon-beta is a standard treatment for relapsing multiple sclerosis. Interferon-gamma therapy is currently used for chronic granulomatous disease and skin lesions (human papilloma virus related and keloids), but further research is ongoing. Side effects of interferon therapy are common and limit utility. Flulike symptoms are reported by more than 75% and depression by 10-40% of interferon users. Severe adverse effects are less common but may be life threatening, including autoimmune diseases, thrombotic-thrombocytopenic purpura, and acute renal failure. Limited use of interferon therapy during pregnancy has been described, with successful maternal and neonatal outcomes. Use of interferon therapy during early pregnancy is not an indication for termination.

Chagas' disease (American trypanosomiasis) is an endemic parasitic disease in some areas of Latin America. About 16-18 million persons are infected with the aetiological agent of the disease, Trypanosoma cruzi, and more than 100 million are living at risk of infection. There are different modes of infection: (1) via blood sucking vector insects infected with T. cruzi, accounting for 80-90% of transmission of the disease; (2) via blood transfusion or congenital transmission, accounting for 0.5-8% of transmission; (3) other less common forms of infection, eg, from infected food or drinks or via infected organs used in transplants. The acute phase of the disease can last from weeks to months and typically is asymptomatic or associated with fever and other mild nonspecific manifestations. However, life-threatening myocarditis or meningoencephalitis can occur during the acute phase. The death rate for persons in this phase is about 10%. Approximately 10-50% of the survivors develop chronic Chagas' disease, which is characterized by potentially lethal cardiopathy and megacolon or megaoesophagus. There are two drugs available for the aetiological treatment of Chagas' disease: nifurtimox (Nfx) and benznidazole (Bz). Nfx is a nitrofurane and Bz is a nitroimidazole compound. The use of these drugs to treat the acute phase of the disease is widely accepted. However, their use in the treatment of the chronic phase is controversial. The undesirable side effects of both drugs are a major drawback in their use, frequently forcing the physician to stop treatment. The most frequent adverse effects observed in the use of Nfx are: anorexia, loss of weight, psychic alterations, excitability, sleepiness, digestive manifestations such as nausea or vomiting, and occasionally intestinal colic and diarrhoea. In the case of Bz, skin manifestations are the most notorious (e.g., hypersensitivity, dermatitis with cutaneous eruptions, generalized oedema, fever, lymphoadenopathy, articular and muscular pain), with depression of bone marrow, thrombocytopenic purpura and agranulocytosis being the more severe manifestations. Experimental toxicity studies with Nfx evidenced neurotoxicity, testicular damage, ovarian toxicity, and deleterious effects in adrenal, colon, oesophageal and mammary tissue. In the case of Bz, deleterious effects were observed in adrenals, colon and oesophagus. Bz also inhibits the metabolism of several xenobiotics biotransformed by the cytochrome P450 system and its reactive metabolites react with fetal components in vivo. Both drugs exhibited significant mutagenic effects and were shown to be tumorigenic or carcinogenic in some studies. The toxic side effects of both nitroheterocyclic derivatives require enzymatic reduction of their nitro group. Those processes are fundamentally mediated by cytochrome P450 reductase and cytochrome P450. Other enzymes such as xanthine oxidoreductase or aldehyde oxidase may also be involved.

Evaluation and management of patients with suspected thrombotic thrombocytopenic purpura (TTP) continue to be a critical challenge for hematologists. The diagnostic criteria are not precise, often causing uncertainty about whether it is appropriate to initiate plasma exchange (PEX), the essential treatment for TTP. Initiation of PEX remains a clinical decision; severe ADAMTS13 (< 10% activity) deficiency alone is neither sufficiently sensitive nor specific for the diagnosis of TTP. However, patients who do have severe acquired ADAMTS13 deficiency define the characteristic clinical features of TTP, the response to treatment, and the long-term outcomes. Patients with severe acquired ADAMTS13 deficiency are predominantly young women and the relative frequency of blacks is increased. Patients may present with only microangiopathic hemolytic anemia and thrombocytopenia, neurologic and renal abnormalities are often not present, fever rarely occurs; the complete "pentad" of these clinical features almost never occurs in current practice. Response to PEX is typically rapid but may not be sustained when PEX is stopped. Use of corticosteroids and rituximab has decreased the number of PEX treatments required to achieve a remission and has resulted in fewer PEX-related major complications. Relapse (in approximately 40% of patients) may be the most apparent risk after recovery, but long-term health outcomes are also very important. Minor cognitive abnormalities are common, the frequency of depression is increased, and the frequency of hypertension is increased. Careful long-term follow-up of TTP patients is essential.

Thrombotic thrombocytopenic purpura (TTP), immune thrombocytopenia (ITP) and acquired haemophilia are very rare haemorrhagic disorders (1) associated with surgery, hospitalization (2) and death being reported (3). Despite the rapid development of interventional techniques, therapeutic options for patients with these illnesses remain limited. We suppose that depression and anxiety disorders appear more frequently than in the normal population in patients with rare haemorrhagic disorders.

After recovery from an acute episode of acquired thrombotic thrombocytopenic purpura (TTP), patients often describe problems with memory, concentration, and endurance. We have previously reported the occurrence of depression and cognitive impairment in these patients. In this study, we describe the frequency, severity, and clinical course of depression and cognitive impairment. Fifty-two (85%) out of 61 eligible Oklahoma Registry patients who had recovered from TTP, documented by ADAMTS13 activity <10%, have had at least one (median, four) evaluation for depression over 11 years using the Beck Depression Inventory-II; 31 (59%) patients screened positive for depression at least once; in 15 (29%), the results suggested severe depression at least once. Nine of these 15 patients had a psychiatric interview, the definitive diagnostic evaluation; the diagnosis of major depressive disorder was established in eight (89%) patients. In 2014, cognitive ability was evaluated in 33 patients by the Montreal Cognitive Assessment and the Repeatable Battery for Assessment of Neuropsychological Status (RBANS). Both tests detected significant cognitive impairment in the patients as a group. Fifteen out of the 33 patients had been evaluated by extensive cognitive tests in 2006. The 2014 RBANS results were significantly worse than the 2006 results for the overall score and two out of the five RBANS domains (immediate and delayed memory). Neither depression nor cognitive impairment was significantly associated with the occurrence of relapses or ADAMTS13 activity <10% during remission. These observations emphasize the importance of screening evaluations for depression and cognitive impairment after recovery from acquired TTP.

Although risk for relapse may be the greatest concern following recovery from acquired, autoimmune thrombotic thrombocytopenic purpura (TTP), there are multiple other major health issues that must be recognized and appropriately addressed. Depression may be the most common disorder following recovery from TTP and may be the most important issue for the patient's quality of life. Severe or moderate depression has occurred in 44% of Oklahoma Registry patients. Recognition of depression by routine screening evaluations is essential; treatment of depression is effective. Minor cognitive impairment is also common. The recognition that cognitive impairment is related to the preceding TTP can provide substantial emotional support for both the patient and her family. Because TTP commonly occurs in young black women, the frequency of systemic lupus erythematosus, as well as other autoimmune disorders, is increased. Because there is a recognized association of TTP with pregnancy, there is always concern for subsequent pregnancies. In the Oklahoma Registry experience, relapse has occurred in only 2 of 22 pregnancies (2 of 13 women). The frequency of new-onset hypertension is increased. The most striking evidence for the impact of morbidities following recovery from TTP is decreased survival. Among the 77 patients who survived their initial episode of TTP (1995-2017), 16 (21%) have subsequently died, all before their expected age of death (median difference, 22 years; range 4-55 years). The conclusion from these observations is clear. Following recovery from TTP, multiple health problems occur and survival is shortened. Therefore, careful continuing follow-up is essential.
