Sequelae of the initial attack of acute rheumatic fever in children from north India. A prospective 5-year follow-up study.

We determined the outcome of acute rheumatic fever in 85 children from North India who had received regular antistreptococcal prophylaxis after their first attack. By the end of the 5-year follow-up, 33 patients had rheumatic heart disease. Mitral insufficiency, the most common valvular lesion, appeared in 91% of the patients, whereas mitral stenosis developed in only 18%. Initial carditis, congestive heart failure, cardiomegaly or moderate-to-severe mitral insufficiency significantly increased the risk of rheumatic heart disease (p less than 0.001). The recurrence rate of acute rheumatic fever in children who received continuous prophylaxis was 0.006 per patient-year. Most recurrence (92%) mimicked the first attack and produced further cardiac damage in five patients with carditis and in one patient with chorea. Cardiac status during the first attack of rheumatic fever and the continuity of prophylaxis were the major determinants of outcome. Statistical comparisons disclosed that with continuous prophylaxis, the prevalence rate, evolution and clinical spectrum of the sequelae of acute rheumatic fever in children from India do not differ significantly from those in the West.

Prospective 12-year follow-up study of clinical and hemodynamic sequelae after deep vein thrombosis in low-risk patients (Zürich study).

BACKGROUND: No prospective study of the long-term sequelae of more than 10 years after acute deep vein thrombosis exists so far. Therefore, 58 low-risk patients with DVT were included in a prospective study to evaluate the natural history of postthrombotic syndrome. METHODS AND RESULTS: Clinical and hemodynamic examinations were performed at the time of admission; after 3, 6, and 12 months; after the 2nd, 3rd, 4th, 5th years; and finally after the 12th year. All patients received heparin initially and oral anticoagulants subsequently. After 12 years, 64% of the patients exhibited normal findings. Mild skin changes were found in 28%, marked trophic changes in 5%, and only one venous ulcer occurred. Regular use of compression stockings was reported by 54% of the patients with multilevel thrombosis. Although mean maximum venous outflow was significantly reduced from the acute event to 12 years later (P<.003) compared with the contralateral leg, a significant (P<.05) improvement was observed 6 months later. Recanalization of calf vein thrombosis was detected by Doppler sonography after 3 months. Sixty-four percent of the multilevel thromboses were recanalized completely or in part after 1 year; in 69%, valvular incompetence was found. CONCLUSIONS: In contrast to earlier reports, this prospective study up to 12 years after deep vein thrombosis demonstrates a low incidence of postthrombotic syndrome by administration of oral anticoagulants and regular compression therapy. However, the adverse clinical event rate (mortality 14%) and a recurrence rate of 24% show that the prognosis after deep vein thrombosis does not appear favorable even in low-risk patients.

Comparison of microembolism detected by transcranial Doppler and neuropsychological sequelae of carotid surgery and percutaneous transluminal angioplasty.

BACKGROUND AND PURPOSE: Percutaneous transluminal angioplasty (PTA) is currently being assessed for the treatment of carotid stenosis. In comparison with carotid endarterectomy (CEA), there is evidence of an increased risk of cerebral microembolism during the procedure. We have sought evidence of any neuropsychological sequelae of carotid PTA and compared it with CEA to demonstrate the relative safety of the 2 treatment options. METHODS: The neuropsychological outcomes after CEA and PTA were compared in 2 matched groups of patients with severe symptomatic carotid stenosis, 96% of whom had been randomized in the Carotid and Vertebral Artery Transluminal Angioplasty Study (CAVATAS), at a single center. Transcranial Doppler insonation of the middle cerebral artery was used to measure cerebral reactivity in response to carbon dioxide inhalation before treatment and then to detect microembolization of the ipsilateral cerebral hemisphere and measure changes in blood flow velocity during the procedures. The performance on a neuropsychological test battery administered before, 6 weeks after, and 6 months after the procedure was compared in 20 patients undergoing PTA and 26 having CEA. RESULTS: At 6 weeks, 5 patients in each group showed a similar decline in neuropsychological performance; global measures showed no significant difference between the 2 procedures, despite a significantly higher incidence of microemboli during PTA. Both groups showed a marked reduction in anxiety after treatment. CONCLUSIONS: The findings provide some reassurance that PTA is not associated with greater cerebral complications than CEA, despite the higher embolic load recorded by transcranial Doppler ultrasonography during angioplasty.

Effect of clopidogrel premedication in off-pump cardiac surgery: are we forfeiting the benefits of reduced hemorrhagic sequelae?

BACKGROUND: Premedication with clopidogrel has reduced thrombotic complications after percutaneous coronary revascularization procedures. However, because of the enhanced and irreversible platelet inhibition by clopidogrel, patients requiring surgical revascularization have a higher risk of bleeding complications and transfusion requirements. A principal benefit of surgical coronary revascularization without cardiopulmonary bypass is its lower hemorrhagic sequelae. The purpose of this study was to evaluate the effect of preoperative clopidogrel administration in the incidence of hemostatic reexploration, blood product transfusion rates, morbidity, and mortality in patients undergoing off-pump coronary artery bypass graft surgery using a large patient sample and a risk-adjusted approach. METHODS AND RESULTS: Two hundred eighty-one patients (17.9%) did and 1291 (82.1%) did not receive clopidogrel before their surgery, for a total of 1572 patients undergoing isolated off-pump coronary artery bypass graft surgery between January 2000 and June 2002. Risk-adjusted logistic regression analyses and a matched pair analyses by propensity scores were used to assess the association between clopidogrel administration and reoperation as a result of bleeding, intraoperative and postoperative blood transfusions received, and the need for multiple transfusions. Hemorrhage-related preoperative risk factors identified in the literature and those found significant in a univariate model were used. The clopidogrel group had a higher likelihood of hemostatic reoperations (odds ratio [OR], 5.1; 95% confidence interval [CI], 2.47 to 10.47; P<0.01) and an increased need in overall packed red blood cell (OR, 2.6; 95% CI, 1.94 to 3.60; P<0.01), multiple unit (OR, 1.6; 95% CI, 1.07 to 2.48; P=0.02), and platelet (OR, 2.5; 95% CI, 1.77 to 3.66; P<0.01) transfusions. Surgical outcomes and operative mortality (1.4% versus 1.4%; P=1.00) were not statistically different. CONCLUSIONS: Clopidogrel administration in the cardiology suite increases the risk for hemostatic reoperation and the requirements for blood product transfusions during and after off-pump coronary artery bypass graft surgery.

Long-term pulmonary sequelae in children with congenital diaphragmatic hernia.

Neonates with congenital diaphragmatic hernia (CDH) often suffer from respiratory insufficiency due to lung hypoplasia and pulmonary hypertension. Artificial ventilation is frequently required, and this leads to a high incidence of bronchopulmonary dysplasia. Long-term follow-up studies have shown persisting airway obstruction. To evaluate the long-term pulmonary sequelae in CDH, we studied 40 CDH patients of age 7 to 18 yr (median 11.7 yr) and 65 age-matched controls without CDH and lung hypoplasia who underwent similar neonatal treatment. Mild airway obstruction was found in both groups with more peripheral airway obstruction in CDH patients than in control subjects. Both groups had normal TLC and single-breath carbon monoxide diffusion capacity (DLCO). CDH patients had increased residual volume (RV) and RV/TLC compared with controls. Increased airway responsiveness to methacholine (MCH) was common but bronchoconstriction to inhaled metabisulfite (MBS) was rare both in CDH and control subjects. We conclude that this group of CDH patients has minor residual lung function impairment. Mild airway obstruction and increased airway responsiveness to inhaled MCH but not to MBS suggest that structural changes in distal airways are involved and not autonomic nerve dysfunction. Both artificial ventilation in the neonatal period and residual lung hypoplasia seem important determinants of persistent lung function abnormalities in CDH patients.

Neuropsychological sequelae and impaired health status in survivors of severe acute respiratory distress syndrome.

Acute respiratory distress syndrome (ARDS) is a disease of acute respiratory failure manifested by severe hypoxemia with a high mortality rate. Previous outcome studies of ARDS have assessed survival and/or pulmonary function as the primary outcome variables. Cognitive or psychological outcomes following ARDS have not been described, despite the possibility that ARDS patients are at risk for brain injury through hypoxemia or other mechanisms. In the current study 55 consecutive ARDS survivors completed a battery of neuropsychological tests and questionnaires regarding health status, cognitive and psychological outcomes at the time of hospital discharge and 1 yr after onset of ARDS. At hospital discharge, 100% (55 of 55) of survivors exhibited cognitive and affective impairments, as well as problems with health status which affected their quality of life. At 1 yr after ARDS, 17 of 55 (30%) patients still exhibited generalized cognitive decline. Forty-three of 55 (78%) patients had all or at least one of the following: impaired memory, attention, concentration and/or decreased mental processing speed. One year after ARDS a substantial portion of ARDS survivors exhibit impaired health status and cognitive sequelae which may be due to hypoxemia, emboli, inflammation, drug toxicity, and/or other etiologies.

Sequelae of cytomegalovirus pulmonary infections in lung allograft recipients.

Indirect effects of cytomegalovirus (CMV) infections in lung transplant recipients (LTX) have not previously been described in detail. We compared spirometric results, development of chronic rejection, rates of respiratory superinfections, and mortality as long as 2 yr after transplantation, between 62 LTX who never developed CMV (CMV-) and 56 LTX with a history of CMV pulmonary infections (CMV+). Initial spirometric parameters were near identical for both groups, but determinations > or = 6 months after transplantation showed that expiratory flows of the CMV+ were significantly reduced. Actuarial prevalences of chronic allograft rejection (CR) at 2 yr were highest among CMV+ with biopsy-proved pneumonitis (74%) compared with 22% among CMV- (p < 0.038). Bacterial or fungal pneumonias developed in 58.9% of the CMV+, whereas the rate among CMV- was 38.7% (p < 0.05). Only 36% of LTX with CMV pneumonitis lived 2 yr compared with 70% survival for CMV- (p < 0.016). Ganciclovir treatment of CMV infections decreased rates of respiratory superinfections and improved survival of patients, but it did not appear to affect subsequent development of CR. We conclude that CMV pulmonary infections among LTX result in serious late sequelae and that current treatment is ineffectual for prevention of viral-associated CR in these patients.

Sequelae of respiratory syncytial virus infections. A role for intervention studies.

The association between respiratory syncytial virus (RSV) infections in infancy and respiratory abnormalities later in life has been attributed both to a direct effect of the infection itself and to an inherent susceptibility. Observational studies do not allow a rigorous test of these hypotheses. Respiratory syncytial virus infection is universal in the first years of life and no uninfected control group exists. Randomized, controlled trials using new prophylactic agents such as vaccines or specific therapeutic agents will provide a powerful test of the relationship between RSV infection and long-term respiratory sequelae.

Immunological studies of post-streptococcal sequelae. Evidence for presence of streptococcal antigens in circulating immune complexes.

Since elevated levels of circulating complexes have been noted to occur in the sera of patients with post-streptococcal sequelae, the possibility that these complexes contained streptococcal antigens within the complex was investigated. Sera from these patients were precipitated with polyethylene glycol to extract a fraction rich in these complexes, which was then injected into rabbits. The rabbit sera were then reacted with both cellular and extracellular fractions obtained from streptococcal strains associated with either acute post-streptococcal nephritis (APSGN) or acute rheumatic fever (ARF) by using immunoelectrophoresis and ELISA techniques. The data demonstrate that both ARF and APSGN complexes contain streptococcal antigens. However, APSGN complexes react uniquely to certain extracellular antigens present in those strains associated with nephritis, while ARF complexes react specifically to certain streptococcal extracellular antigens excreted by strains associated with rheumatic fever. Neither of the two groups of complexes appear to contain streptococcal antigens related to any cellular antigens derived from the group A streptococcus. Additionally, a rabbit serum immunized with streptococcal extracellular products reacted directly with complexes isolated from nephritis patients. Removal of the gamma globulin by absorption with an anti-human Fc serum resulted in the concomitant loss of reactivity with the anti-streptococcal serum, strongly suggesting an intimate association of the streptococcal antigen with these complexes. The presence of streptococcal antigens within the circulating immune complex of patients with APSGN coupled with their specific presence in those strains associated with post-streptococcal glomerulonephritis argues strongly for a causal role of these antigens in the disease process.

Psychiatric and neurologic sequelae of infectious mononucleosis.

Infectious mononucleosis is usually thought to be a benign disease with occasional neurologic sequelae. Depression, incoordination, a reduction in intellectual ability, and altered EEG patterns were found in two patients; one recovered and the other seemed to have permanent residual effects. The possibility of tranylcypromine as a treatment for the depression and appropriate counselling of patient and family are discussed.

Sexual abuse histories and sequelae in female psychiatric emergency room patients.

The charts of 100 nonpsychotic female patients in a psychiatric emergency room were reviewed to locate references to history of sexual molestation: 50 charts were selected at random from emergency room files, and 50 charts had been written by clinicians asked to query abuse history. A substantially higher rate of sexual abuse was found for patients who had been directly asked about sexual molestation (70%) than for the random sample (6%). Further analysis linked molestation history to suicidality, substance abuse, sexual difficulties, multiple psychiatric diagnoses, and axis II traits or disorders--especially borderline personality. Severe abuse and multiple abusers best predicted psychiatric sequelae.

Sequelae of bereavement resulting from suicide.

Although clinical experience suggests that individuals who have been bereaved as a result of suicide may be especially vulnerable to adverse sequelae, such as unusually severe grief or increased risk of committing suicide themselves, the idea that this type of bereavement is special has received only limited systematic investigation. The authors review the literature on the subject, with special attention to the clinical and research evidence about whether bereavement resulting from suicide is different from bereavement due to other types of death, and make suggestions for further clinical and epidemiological research on this question.

Family sequelae after a child's death due to cancer.

In a small study assessing the psychologic sequelae on disadvantaged families after a child's death from cancer, a high incidence of psychologic problems was found. The implication is that the coping mechanisms failed partially as a result of inadequate anticipatory griefing.

Experience of families with very low birthweight children with neurologic sequelae.

To describe the quality of life for surviving very low birthweight (VLBW, less than 1.5 kg) children and their families, the authors interviewed the parents of 22 neurologically abnormal VLBW children, 3 to 7 years after their birth and compared them to the parents of 15 neurologically normal VLBW children. The infants were born between 1976 and 1979, (mean birthweight, 1.2 kg; mean gestational age, 30 weeks). They included three with spastic quadriplegia, 14 with spastic diplegia, and five with hydrocephalus. Eight children were not walking. Seven families rated their child's neurologic problem as severe, while 15 rated the problem as mild. Neurologically abnormal children tended to display more screaming and crying than the normal children. Cost of ongoing medical care was a problem for families of nine neurologically abnormal as compared with two families of normal children. The abnormal children required a total of 61 postneonatal rehospitalizations versus 11 in the normal group. Families of neurologically abnormal children reported on significant major changes in their personal lives for the care of their child. Both groups of parents reported heightened appreciation of their child. Plans for future children were affected in both. Parents identified an urgent need for better medical information, education of pediatricians regarding preterm development and neurologic sequelae, and better contact and support among parents themselves.

Long-term sequelae of pneumococcal meningitis in children.

The purpose of this study was to assess the long-term effects of pneumococcal meningitis in children. From 1967 to 1988, a total of 90 children were admitted to the Hospital for Infectious Diseases, Thessaloniki, Greece, with the diagnosis of pneumococcal meningitis. Sixteen patients died in the hospital as a direct result of meningitis. Eleven others were excluded from the study (neurologic deficits prior to onset of meningitis, two; death subsequent to hospitalization, two; recurrent meningitis, seven). Of the remaining 63 survivors, we were able to evaluate 47 patients (75%). Evaluation was performed 4 to 23 years (mean 12.3 +/- 5.8 years) after discharge. Forty patients returned to hospital for evaluation, and seven were evaluated by their primary physicians, who sent information by a standardized questionnaire. The following examinations were carried out: history, physical and neurologic examination, ophthalmologic and hearing evaluation, and psychometric testing. Fourteen patients (30%) had at least one neurologic handicap; nine (19%) had mental retardation, eight (17%) hearing loss, seven (15%) seizure disorder, five (11%) motor defects, and one each (2%) behavioral problems and visual impairment. The presence of coma was the strongest predictor of increased morbidity. The high frequency of long-term sequelae observed in our study supports the need of an effective vaccine.

Cognitive, neuropsychological, and academic sequelae in children with leukemia.

The literature concerning the cognitive and neuropsychological sequelae of children in whom leukemia has been diagnosed indicates that these children exhibit deficits in cognitive and neuropsychological functioning and academic achievement in response to the iatrogenic effects of central nervous system (CNS) irradiation. Preliminary studies suggest that similar emanative effects may follow intrathecal chemotherapy, an alternative to CNS irradiation for children given a favorable prognosis. It is concluded that treatment advances have lengthened the life expectancy of many children with leukemia, thereby changing their prognosis to a more favorable one. This has resulted in a recognition of the difficulties accompanying school reentry. In light of their documented neuropsychological, academic, and social adjustment problems, many of these children require special education services.
