[Outcome and tendency of late convalescence in icterohemorrhagic leptospirosis].

To elucidate the time of onset and duration of complications of icterohemorrhagic leptospirosis (IL), a clinical course of early and late convalescence was analysed in 170 patients who were followed up for 1.5-9 years. It was found that affection of hepatobiliary, urinary, cardiovascular and nervous systems persisted for a year after the acute disease in 65.3, 67.6, 31.8 and 13.5% patients, respectively. The organ of vision was affected for 1 year in 7.1% patients. A total of 86% patients retained the above disorders in early convalescence (for a year). In early convalescence the author observed development of such diseases as chronic hepatitis, a latent stage of chronic renal failure, myocardiac myocardiodystrophy. Nervous and ocular complications manifested both in early and late convalescence (4-18 months). The complications combined in 66.0% cases, renal dysfunction + hepatic dysfunction being most frequent. Endogenic infection foci activated within 6 months after IL. In 19.4% patients, the pathological process prolonged up to 1.5 years. In 5.3% patients it can last for several years. It is concluded that IL patients should be followed up for 1.5 years, combined pattern of organ affection typical for IL should be taken into account.

Potential for hepatic and renal dysfunction during influenza B infection, convalescence, and after induction of secondary viremia.

Whether infection with influenza B virus alters hepatic function was examined in the ferret. Also, the possibility that viral-specific antibodies (Ab) could be produced well before their detection in serum was explored. During the febrile period of influenza, reductions in the serum potassium, anion gap, ammonia, albumin and CPK and elevations of the BUN, creatinine and the GGTP levels occurred. With convalescence, the electrolytes, BUN and creatinine normalized, FFA, SGPT and CPK levels rose and the serum GGTP rose even further. Hepatic fatty acid (FA) oxidation, ornithine transcarbamylase (OTC) and carnitine palmitoyltransferase (CPT) activities were minimally altered and liver ATP and total lipid content remained normal. Following experimental secondary viremia, serum FFA continued to rise, TG decreased and CPK remained elevated while SGPT and GGTP levels normalized. In the liver, FA oxidation and OTC rates remained unchanged but CPT activity was inhibited and the liver content of ATP was significantly reduced. Immune complex (IC) protein recovered from postmicrosomal supernatant fractions by polyethylene glycol precipitation was progressively increased in livers from convalescent and viremic animals. While the amount of IC protein recovered in the spleen also increases during convalescence, this is not the case after viremia when the IC formed seem to be processed largely by the liver. By SDS/PAGE, the major proteins identified in the IC were IgM and other viral proteins. However, the viral proteins could not be validated by immunoblot with Ab produced against purified influenza B hemagglutinin (HA) and neuraminidase (NA) most probably due to phagocytic alterations of glycoprotein immunodeterminants. These findings indicate that during influenza, convalescence and post viremia changes in the concentrations of several serum and liver components occur that reflect hepatic involvement. Also, antiviral Ab, largely IgM, appears to be produced early, complexes with Ag and can be found sequestered in both the liver and spleen at a time when Ab is not detectable in the serum.

Convalescent phase of bipolar disorder.

The interepisode interval in bipolar disorder has been relatively unstudied, in part because patients are generally considered to be well during that period. The author proposes that a symptomatic convalescent phase follows acute episodes of mania and depression and precedes the return to the entirely well state. A case is presented of a 15-month convalescence that followed a manic episode. The most prominent features of the convalescence were its long duration, its saw-toothed pattern of remitting and recurring symptoms, and the presence of dysphoria. The fluctuation of dysphoric symptoms was at times associated with and at times independent of life events and was independent of lithium levels. Supportive psychotherapy is apparently a critical element in the management of this phase. Questions about the nature and optimal management of the convalescent period are raised.

Smaller ports result in shorter convalescence after laparoscopic varicocelectomy.

Minimal postoperative pain and a shorter convalescence after laparoscopic surgery are attributable to the small puncture wounds produced to accommodate trocars. We investigated the effects of trocar size on convalescence after 37 laparoscopic varicocelectomies. The initial 21 patients underwent the procedure with 2, 10 mm. ports and 1, 5 mm. port, while the last 16 underwent surgery with 3, 5 mm. ports. Postoperative convalescence was evaluated by a questionnaire. The patients who underwent the 5 mm. port technique achieved complete pain relief, returned to work and could resume work at preoperative levels significantly earlier than those who underwent the 10 mm. port technique (2.4 +/- 1.5 days versus 5.9 +/- 4.8 days, p < 0.03; 8.2 +/- 3.1 days versus 10.0 +/- 2.5 days, p < 0.03, and 10.2 +/- 4.4 days versus 14.3 +/- 6.5 days, p < 0.03, respectively). Our study showed that laparoscopic surgery with smaller ports resulted in less postoperative pain and a shorter convalescence than when larger 10 mm. ports were used.

Drug prescribing for the elderly outpatient and for those confined to convalescent hospitals. How the new OBRA laws will change some established habits.

Families as well as state and federal inspectors have long complained of unnecessary drugs prescribed by physicians, especially antipsychotic drugs, used as chemical restraints in skilled nursing facilities. The US Congress passed the Omnibus Budget Reconciliation Act of 1987 (OBRA), also commonly referred to as the Nursing Home Reform Act, to prevent inappropriate prescribing of medications in long-term care facilities that receive funds from Medicare and Medicaid. The regulations became effective October 1, 1990 and were enforced starting in 1991. Future regulations regarding drug labeling of all prescriptions, including biologics, are being proposed by the Food and Drug Administration for the protection of the elderly from adverse drug reactions in the community. A survey was performed in a 132-bed convalescent hospital in Los Angeles to assess the most frequent types of drugs ordered and the most frequent diseases found in this facility. The study revealed the most frequent diagnosis and drugs ordered on admission to the facility from acute facilities, home, and board and care facilities. The diagnosis differed, and the drugs the patients were taking differed markedly at the time of admission. Attending physicians in the convalescent hospital changed many of the drugs to meet the needs of the convalescent hospitals as well as the new OBRA regulations. Future prescribing habits of physicians will be modified in convalescent hospitals, and the results will need further studies to assess its effect on patient care.

[Ambulatory laparoscopic cholecystectomy. Feasibility and convalescence].

UNLABELLED: The purpose was to describe feasibility of and convalescence after laparoscopic cholecystectomy in a day case set up in this prospective, open, and descriptive study. Fifty consecutive patients referred for elective cholecystectomy participated. An overnight stay was planned for 13 patients, (12 because they lived alone, one because of pulmonary disease ASA III). The operation was in all cases performed under combined epidural-general anaesthesia. The primary issues were duration of hospital stay, reasons for delayed discharge, frequencies of nausea and vomiting, as well as duration of convalescence and reasons for postponement of return to work or recreational activities. Twenty-six patients (of 37 candidates for day case surgery) were discharged on the day of surgery and 16 on the first postoperative day. Eleven patients had nausea, and three vomited during the first three postoperative hours. Pain was the most common contributory reason for overnight stay (17 patients, eight of these being planned day-case patients who stayed overnight). The patients were recommended to resume work and recreational activities after 48 hours, but 35 patients did not observe this recommendation. The median number of days off work or recreational activity was four days (2-8), including the day of surgery. Pain was the most common contributory reason (19 patients). CONCLUSIONS: Laparoscopic cholecystectomy can be performed as an outpatient operation in more than half of all patients, in approximately 70% of patients not living alone, and with only 15% of the patients requiring more than one over-night stay. Postoperative pain is the primary reason for both delayed discharge and prolonged convalescence. Up to one week's duration of convalescence is recommended.

Platelet degranulation and monocyte-platelet complex formation are increased in the acute and convalescent phases after ischaemic stroke or transient ischaemic attack.

Flow cytometric studies suggest that platelets are activated in ischaemic stroke or transient ischaemic attack (TIA). However, few studies have measured circulating leucocyte-platelet complexes in this patient population. Whole blood flow cytometry was used to quantify the expression of CD62P-, CD63-, and PAC1-binding, and the percentages of leucocyte-platelet complexes in acute (1-27 d, n = 79) and convalescent (79-725 d, n = 70) ischaemic cerebrovascular disease (CVD) patients compared with controls without CVD (n = 27). We performed a full blood count, and measured plasma levels of soluble P-selectin, soluble E-selectin, and von Willebrand factor antigen (VWF:Ag) as additional markers of platelet and/or endothelial cell activation. The median percentage CD62P expression and the median percentage monocyte-platelet complexes were higher in both acute and convalescent CVD patients than controls (P </= 0.02). The mean white cell count and mean VWF:Ag levels were significantly elevated in the acute and convalescent phases after ischaemic stroke or TIA (P </= 0.02). Otherwise, there was no significant increase in any other marker of platelet or endothelial activation in CVD patients. There was a positive correlation between the percentage expression of CD62P and the percentages of both neutrophil-platelet and monocyte-platelet complexes in the acute phase, and the percentages of all leucocyte-platelet complexes in the convalescent phase after ischaemic CVD. This study provides evidence for ongoing excessive platelet and/or endothelial activation in ischaemic CVD patients despite treatment with antithrombotic therapy.

[Rehabilitation therapy of convalescents after hemorrhagic fever with renal syndrome in outpatient clinic].

AIM: To assess clinical efficacy of mineral water and perindopril in convalescents after hemorrhagic fever with renal syndrome (HFRS) in outpatient setting. MATERIAL AND METHODS: The study covered 113 HFRS convalescents. HFRS was confirmed serologically. The patients were divided into three groups: group 1 (n = 50) received no rehabilitation care; group 2 (n = 32) drank mineral water "varzi-yatchi"; group 3 (n = 31) drank mineral water and took perindopril (2 mg/day). After-treatment continued for 30-35 days. The effect was assessed by a complex of clinical-laboratory and functional tests for examination of renal functions (Reberg-Tareev, Zimnitsky tests, estimation of uric acid clearance and renal functional reserve, an 18-hour water deprivation test). RESULTS: Mineral water varzi-yatchi and perindopril had a favourable effect on clinical condition and renal functions of HFRS convalescents. Compared to the controls (p < 0.05), they had less severe weakness, lumbar pains, edema of the lower limbs; positive changes in intraglomerular hemodynamics, renal transport of beta 2-microglobulin (MG), uric acid transport. CONCLUSION: It is shown that HFRS convalescents have defective glomerular and tubulointerstitial systems of the kidneys. These disorders demand a differential therapeutic approach. Drinking mineral water improves some tubular functions. The addition of perindopril is necessary in detection of arterial hypertension, impairment of intraglomerular hemodynamics, hyperexcretion of beta 2-MG, osmoregulating renal dysfunction.

[Protective effect of specific antibody in serum of convalescent patient with SARS].

OBJECTIVE: To investigate inhibitory effect of serum severe acute respiratory syndrome (SARS) -specific antibodies from convalescent patients after half an year of onset on SARS-CoV-mediated cytopathic response. METHODS: SARS-CoV immunoglobulin G (IgG) antibody was determined by enzyme linked immunoadsorbent assay (ELISA). Twelve serum samples from convalescent patients, diluted by 1:8 with maintenance medium, were mixed with the three dilution supernatants of SARS-CoV. SARS-CoV were isolated, cultured and identified by the Guangzhou Institute of Respiratory Disease, and cultured with Vero E6 cell suspension. The extent of cytopathic response was observed. RESULTS: The absorbance (A) value of SARS-CoV IgG antibody ranged from 0.81 to 2.06 in patients after half an year of SARS onset, and form 0.79 to 2.01 in patients before half an year of SARS onset. The extent of cytopathic response was decreased by more than 25% in all 12 convalescent patients, as compared with control serum. CONCLUSION: The A value of SARS-CoV IgG antibody in serum of convalescent patients tended to elevate in half an year after SARS onset. SARS-CoV IgG antibody could inhibit SARS-CoV-mediated cytopathic response, indicating it might be one of protective antibodies.

Immunologic comparisons of Pneumocystis carinii strains obtained from rats, ferrets, and mice using convalescent sera from the same sources.

Pneumocystis carinii (Pc) infections were developed in animals immunosuppressed by dexamethasone treatment either from activation of latent infection (ferret) or trans-tracheal inoculation of Pc obtained from infected lungs of the homologous species (rat, mouse). Convalescent antisera were obtained by stopping dexamethasone treatment after 2-4 wk and allowing 5-8 wk for recovery. Parasites from infected lungs were purified by differential filtration, solubilized in loading buffer, subjected to sodium dodecyl sulfate- polyacrylamide gel electrophoresis, and blotted to polyvinylidene fluoride sheets for Western analysis. Antisera from each animal species were reacted on Western blots of antigens from rat, ferret, and mouse. Each combination of antigen and antibody from the same species of animal showed reaction with 5 or more bands of Pc antigen. Convalescent mouse antibody did not react with rat or ferret antigens. Convalescent rat antibody reacted with a mouse antigen at about 66 kDa but not with ferret antigen, and convalescent ferret antibody showed minimal, probably non-specific reactions with both rat and mouse antigens. Variations in reactions indicate antigenic differences in Pc strains infecting these animals.

Widespread Molecular Imprints in the Serum Proteome of COVID-19 Convalescents Uncovering Immune System Sequelae.

Post-COVID-19 sequelae have become an emerging global health issue, but the mechanisms for the sustained susceptibility of convalescents to the sequelae remain poorly understood. Here we report the use of a restricted open-search approach to explore the molecular imprints of SARS-CoV-2 infection left on the proteome of 412 COVID-19 patients and convalescences. A total of 827 non-standard amino acid variations, chemically modified residues as well as post-translational modifications, termed non-coded amino acids (ncAAs), are found spreading over 29,814 sites in patient's serum proteins. Markedly, widespread ncAAs are induced and sustainedly imprinted on the serum proteome predominately perturbing the immunoglobulin-mediated immune response, complement activation and coagulation regulation even 12 months after recovery. Sustained amino acid variations and chemical modifications are found in the complementary‑determining regions (CDRs) of the variable region of immunoglobulin contributing to the interactions between the emerging antibody and antigens; durable chemical amino acid modifications found in the hyper ncAA-modified regions of the constant region of immunoglobulin important for the interaction with the complement and regulatory receptors. In the complement system, inducible ncAAs are memorized in the components essential for the complement activation, amplification cascades and membrane attack processes. Thus, the workflow described in this study can be used to identify the molecular imprints of viral infection at the proteomic scale, particularly the specific antibodies and the immune targets left in COVID-19 patients and convalescents.

Occult lifelong persistence of infectious hepadnavirus and residual liver inflammation in woodchucks convalescent from acute viral hepatitis.

Traces of hepatitis B virus (HBV) genome can persist for years following recovery from hepatitis B. To determine overall duration, molecular characteristics, and pathological implications of this serologically undetectable form of hepadnaviral carriage, we have analyzed the expression of transcriptionally active virus genomes, their infectivity, and examined liver alterations during the natural lifespan of woodchucks convalescent from acute infection with HBV- related woodchuck hepatitis virus (WHV). In this study, we document lifelong persistence of scanty amounts of replicating virus both in the liver and lymphatic system after spontaneous resolution of an episode of experimental hepadnaviral hepatitis. Antibodies to virus nucleocapsid (core) were found to be the most reliable immunovirological marker coexisting with occult infection. In the majority of convalescent woodchucks, serial liver biopsies showed protracted minimal to mild necroinflammation with periods of normal morphology; however, hepatocellular carcinoma (HCC) ultimately developed in 2 of 9 animals studied. Inocula derived from lymphoid cells of convalescent animals induced classical acute hepatitis in virus-naive woodchucks that progressed to chronic hepatitis and HCC in 1 of the animals, demonstrating infectivity and pathogenic competence of the carried virus. Our results reveal that low levels of infectious WHV and residual hepatic inflammation usually continue for life after resolution of hepatitis and that this recovery does not avert HCC development. They also demonstrate that, in addition to the liver, the lymphatic system is the site of the occult lifelong maintenance of replicating hepadnavirus.

The response to an oral glucose load during convalescence from hypoxia in newborn infants.

The ability to tolerate an oral glucose load during convalescence from hypoxia was studied in four term and 11 premature appropriate-for-gestational-age infants by sequential measurements of the changes occurring in blood pH, bicarbonate, plasma lactic acid, and plasma glucose following an oral glucose load. All infants developed metabolic acidosis and lactic acidemia after the oral glucose load. The maximum fall in blood bicarbonate occurred at 30 minutes, and the maximum rise in plasma lactic acid concentration was attained at 60 minutes. The metabolic changes were found to be more severe in infants given the oral glucose load early in their convalescence and in those infants less than 10 days of age. The absorption of glucose was also decreased in these infants, as shown by a reduced rise in blood sugar. These observations indicate that newborn infants, term or premature, tolerate glucose loads poorly during convalescence from hypoxia.

Ventilatory changes in convalescent infants positioned in car seats.

Because premature infants have been shown to be at risk for hypoxia and bradycardia when positioned in standard car seats, this study was done to confirm this finding in a larger sample, to investigate convalescent term infants in the neonatal intensive care unit for respiratory compromise in car seats, and to determine the physiologic mechanism or mechanisms responsible. Extensive multichannel polygraph recordings were obtained and pulmonary function tests were performed on 50 convalescent infants from the neonatal intensive care unit before, during, and after placement in a Cosco-Peterson First Ride car seat. Mean total dynamic compliance, total pulmonary resistance, and work of breathing improved in the car seat. Thirty percent of premature infants experienced hypoxia, bradycardia, or both in a car seat; in this group, tidal volume was lower (p = 0.02). In 11 of 16 infants with abnormal findings, oxygen desaturation was temporally related to episodes of short and mixed apnea. No term convalescent infant experienced respiratory difficulty in a car seat regardless of primary diagnosis. We conclude that premature infants may have respiratory compromise of a multifactorial nature when in car seats. Further development of car seats is necessary if such respiratory problems are to be avoided.

Prospective comparison of short-term convalescence: laparoscopic radical prostatectomy versus open radical retropubic prostatectomy.

OBJECTIVES: To evaluate and compare prospectively the convalescence of patients after laparoscopic radical prostatectomy (LRP) and open radical retropubic prostatectomy (RRP) in a standardized clinical care pathway at a single institution by two surgeons of equal experience and training. METHODS: The study included all 60 patients undergoing LRP and RRP by two fellowship-trained surgeons in their first year of practice. The postoperative care of these patients was uniform and standardized. The medical records were reviewed and convalescence data obtained by an independent urologist and physician's assistant. RESULTS: Of the 60 patients, 24 underwent RRP and 36 underwent attempted LRP; 3 patients were converted from LRP to RRP. The differences in mean age, preoperative prostate-specific antigen level, Gleason score, in-hospital morphine equivalent requirement, time to oral intake, and hospital stay were not statistically significant between the LRP and RRP groups. The operating room time was significantly longer (5.8 +/- 1.2 hours versus 2.8 +/- 0.55 hours, P <0.0001) and the estimated blood loss was significantly lower in the LRP group (533 +/- 212 mL versus 1473 +/- 768 mL, P <0.0001) than in the RRP group. Pain medication use at home was significantly less in the LRP group (9 +/- 13 versus 17 +/- 15 oxycodone tablets, P <0.04), as was the time to complete convalescence (30 +/- 18 days versus 47 +/- 21 days, P <0.002). CONCLUSIONS: Although LRP took almost twice as long to complete as RRP in our initial clinical experience, the patients had a similar hospital course. LRP patients required less pain medication after discharge and had a shorter time to complete recovery than did RRP patients. Additional studies are needed to address long-term cancer control, potency, and continence outcomes to determine the precise role of LRP in the treatment of men with clinically localized prostate cancer.

Baculovirus expressed 2C of foot-and-mouth disease virus has the potential for differentiating convalescent from vaccinated animals.

Determining whether animals have been infected with foot-and-mouth disease virus or vaccinated is important because infected animals frequently become carriers of the virus, shed it intermittently and thus may be the source of new outbreaks of the disease. We had shown previously that the sera of convalescent animals contain antibodies to 2C, a highly conserved non-structural protein, whereas the sera of vaccinated animals do not. This is explained by observation that 2C is retained on the membranes of cells used for growing the virus for vaccine production. In contrast, the non-structural protein 3D, which is released into the medium, is not removed by centrifugation or filtration during vaccine production and therefore stimulates an immune response in both vaccinated and convalescent cattle. In this study we produced 2C and 3D in insect cells infected with recombinant baculoviruses. As demonstrated by serology and electron microscopy, 2C is also retained on the membranes of the insect cells. Both expressed proteins react with sera of convalescent animals, indicating that they are conformationally similar, but the 2C does not react with sera from vaccinated animals. The baculovirus expressed 2C appears to be a suitable antigen for the development of a reliable diagnostic test.

Evaluation of Th1/Th2 ratio and cytokine production profile during acute exacerbation and convalescence in asthmatic children.

BACKGROUND: Th2-type cytokines, such as IL-4 and IL-5, are generally believed to play an important role in the pathogenesis of allergic asthma. In contrast, Th1-type cytokine, especially interferon (IFN)-gamma, is thought to have a downregulatory effect on Th2 immune response cells. Thus, the imbalance of Th1 and Th2 cells may be a key factor in relation to disease severity. OBJECTIVE: The aim of this study is to examine the changes in the Th1/Th2 ratios and cytokine production profiles of asthmatic children at acute attacks and convalescent stages. METHODS: Twelve asthmatic patients were included in this study. The percentages of IFN-gamma- or IL-4-producing cells were determined with a flow-cytometric method of intracellular protein detection. Fresh whole blood obtained from normal controls and patients at two stages was stimulated with brefeldin A, phorbol myristate acetate, and ionomycin for 4 hours. Cells were fixed and stained intracellularly with fluorescein isothiocyanate- or phycoerythrin-conjugated antibody specific to each cytokine in combination with anti-CD4. ELISA assays were applied to measure cytokine concentrations of supernatant from peripheral blood mononuclear cells (PBMC) activated with phorbol myristate acetate and ionomycin for 24 hours. RESULTS: Among CD4+ cells, the percentage of IL-4+ cells decreased significantly from 8.18 +/- 4.77% at acute attacks to 4.18 +/- 1.26% (P < .020) at convalescence. The percentage of IFN-gamma+ cells also decreased from 13.49 +/- 4.21% to 9.03 +/- 5.42% (P < .052). The Th1/Th2 ratios of patients at the two stages were similar, and both were lower than the normal controls. Significantly higher IL-5 and lower IFN-gamma production were detected from activated PBMC of asthmatic patients than normal controls. CONCLUSIONS: The decrease of IFN-gamma+ and IL-4+ cells detected at the single-cell level may explain the potential mechanism of convalescence from acute asthma attacks. High Th1/Th2 ratio and low IL-5 production from the PBMC of normal controls support the idea of a biased Th2 immune response in asthmatic patients.

Risk of subsequent cardiac events in stable convalescing patients after first non-Q-wave and Q-wave myocardial infarction: the limited role of non-invasive testing. The Multicenter Myocardial Ischemia Research Group.

BACKGROUND: Patients recovering from myocardial infarction are frequently evaluated by non-invasive tests for evidence of myocardial ischemia before returning to work or full activity. The purpose of this study was to evaluate the prognostic significance of clinical and non-invasive ischemic test variables assessed in 549 stable, convalescing patients (median 2 months) after their first Q-wave (n = 363) and non-Q-wave (n = 186) myocardial infarction. METHODS: The ischemic tests performed were resting ECG, exercise ECG, ambulatory ECG, and stress thallium scintigraphy. RESULTS: Cardiac events (unstable angina requiring hospitalization, non-fatal reinfarction, or death from cardiac causes) were observed during a mean 23-month follow-up in 57 patients (15.7%) with Q-wave and in 31 of patients (16.7%) with non-Q-wave infarction. In a step-wise Cox regression model, the only significant independent predictors of subsequent cardiac events (P < 0.001) were post-infarction angina and insulin-dependent diabetes mellitus. The type of infarction did not make a significant contribution to the risk of cardiac events (P = 0.29). However, an interaction between infarct type and post-infarction angina was of borderline significance (P = 0.065), with angina associated with more cardiac events in patients with non-Q-wave than in those with Q-wave infarction. None of the ischemic tests contributed significantly to the Cox model in predicting cardiac events in either infarct type. CONCLUSION: Stable convalescing patients who have recovered from first Q-wave and non-Q-wave myocardial infarction have similar long-term prognoses. The occurrence of post-infarction angina is associated with increased risk of cardiac events in patients with both infarct types, with more marked effect in non-Q-wave than Q-wave infarctions. Ischemia detected by non-invasive tests performed in the convalescing phase after myocardial infarction was not prognostically useful in either infarct type.
