RESUMO

INTRODUCTION: In situ reconstruction (ISR) with autologous veins is the preferred method in infectious native aortic aneurysms (INAAs) or vascular (endo)graft infection (VGEI). However, access to biological substitutes can prove difficult and lacks versatility. This study evaluates survival and freedom from reinfection after ISR of INAA/VGEI using the antimicrobial Intergard Synergy graft combining silver and triclosan. METHODS: From February 2014 to April 2020, 86 antimicrobial grafts were implanted for aortic infection. The diagnosis of INAA/VGEI and reinfection was established based on the Management of Aortic Graft Infection Collaboration criteria. Survival was analyzed using the Kaplan-Meier method and log-rank P values. RESULTS: The antimicrobial graft was implanted in 32 cases of INAA, 28 of VGI, and 26 of VEI. The median age was 69.0 (interquartile range: 62.0; 74.0), with a history of coronary artery disease (n = 21; 24.4%), chronic kidney disease (n = 11; 12.8%), cancer (n = 21; 24.4%), and immunosuppression (n = 27; 31.4%). Imaging showed infiltration (n = 14; 16.3%), air (n = 10; 11.6%), and rupture (n = 16; 18.6% including 22 aortoenteric fistulae [AEnF]). Symptoms included fever (n = 37; 43.0%), shock (n = 11; 12.8%), and pain (n = 47; 54.7%). Repair was undertaken through a midline laparotomy in 75 cases (87.2%) and coeliac cross-clamping in 19 (22.1%), suprarenal in 26 (30.2%), plus celiac trunk (n = 3), mesenteric (n = 5), renal (n = 13), or hypogastric (n = 4) artery reconstruction, and omental flap coverage (n = 41; 48.8%). For AEnF, the gastrointestinal tract was repaired using direct suture (n = 14; 16.3%) or resection anastomosis (n = 8; 9.3%). Causative organisms were identified in 74 patients (86.0%), with polymicrobial infection in 32 (37.2%) and fungal coinfection in 7 (8.1%). Thirty-day and in-hospital mortality were 14.0% and 22.1% (n = 12 and 19, respectively, 3 INAA [9.4%], 7 VGI [25.0%], and 9 VEI [34.6%]). Seventy patients (81.4%) had a postoperative complication, 44 (51.2%) of whom returned to the operative room. The 1- and 2-year survival rates were 74.0% (95% confidence interval [CI]: 63.3-82.1) and 69.8% (95% CI: 58.5-78.5), respectively. Survival was significantly better for INAA vs VGEI (P = .01) and worse for AEnF (P = .001). Freedom from reinfection was 97.2% (95% CI: 89.2-99.3) and 95.0% (95% CI: 84.8-98.4) with six reinfections (7.0%) requiring two radiological/six surgical drainage and two graft removals. Primary patency was 88.0% (95% CI: 78.1-93.6) and 79.9% (95% CI: 67.3-88.1) with no significant difference between INAA and VGEI (P = .16). CONCLUSIONS: ISR of INAA or VGEI with the antimicrobial graft showed encouraging early mortality, comparable to the rates found in femoral vein (9%-16%) and arterial allograft (8%-28%) studies, as well as mid-term reinfection. The highest in-hospital mortality was noted for VEI including nearly 50% of AEnF.

RESUMO

Background: This study aimed to systemically explore the risk factors of secondary infection/recurrence after ablation in patients with liver cancer. Methods: Relevant literature in PubMed, EMbase, and Cochrane Library databases were searched with keywords including "liver cancer or carcinoma," "ablation," "infectious or infection or recurrence," and "risk factor or relevant factor or correlative factor or influencing factor." Meta-analyses were performed and forest plots were drawn for risk factors, including the tumor size and location, number of tumor nodules, hepatitis B virus (HBV) DNA levels, serum alpha fetal protein (AFP) levels and serum albumin levels, Child-Pugh Class, and lack of antiviral therapy. A funnel plot was drawn to assess the publication bias. Results: A total of 23 studies were included from the initial 701 potentially relevant articles. Our meta-analyses showed that a large tumor size (odds ratio [OR] = 1.58; 95% confidence interval [CI]: 1.31-1.92); proximity to the colon, large vessels, and large hepatic vein (OR = 4.10; 95% CI: 2.26-7.43); multinodular tumor (OR = 2.10; 95% CI: 1.46-3.03), the higher HBV DNA levels (OR = 1.34; 95% CI: 1.09-0.64); higher serum AFP levels (OR = 1.56; 95% CI: 1.18-2.05), lower serum albumin levels (OR = 1.67; 95% CI: 1.06-2.65); Child-Pugh Class B and Class C (OR = 1.27; 95% CI: 1.05-1.54); and lack of antiviral therapy (OR = 1.75; 95% CI: 0.93-3.28) were associated with an increased risk of post-ablation infection/recurrence in patients with liver cancers. Conclusion: Our results indicated that the tumor size and location, number of tumor nodules, HBV DNA levels, serum AFP levels and serum albumin levels, Child-Pugh Class, and lack of antiviral therapy were the risk factors for post-ablation infection/recurrence in patients with liver cancer. Here, we have provided directions for the clinical prevention of secondary infection/recurrence in patients with liver cancer who underwent ablation therapy.

RESUMO

OBJECTIVE: The optimal revascularization modality following complete resection of aortic graft infection (AGI) without enteric involvement remains unclear. The purpose of this investigation is to determine the revascularization approach associated with the lowest morbidity and mortality using real-world data in patients undergoing complete excision of AGI. METHODS: A retrospective, multi-institutional study of AGI from 2002 to 2014 was performed using a standardized database. Baseline demographics, comorbidities, and perioperative variables were recorded. The primary outcome was infection-free survival. Descriptive statistics, Kaplan-Meier survival analysis, and univariate and multivariable analyses were performed. RESULTS: A total of 241 patients at 34 institutions from seven countries presented with AGI during the study period (median age, 68 years; 75% male). The initial aortic procedures that resulted in AGI were 172 surgical grafts (71%), 66 endografts (27%), and three unknown (2%). Of the patients, 172 (71%) underwent complete excision of infected aortic graft material followed by in situ (in-line) bypass (ISB), including antibiotic-treated prosthetic graft (35%), autogenous femoral vein (neo-aortoiliac surgery) (24%), and cryopreserved allograft (41%). Sixty-nine patients (29%) underwent extra-anatomic bypass (EAB). Overall median Kaplan-Meier estimated survival was 5.8 years. Perioperative mortality was 16%. When stratified by ISB vs EAB, there was a significant difference in Kaplan-Meier estimated infection-free survival (2910 days; interquartile range, 391-3771 days vs 180 days; interquartile range, 27-3750 days; P < .001). There were otherwise no significant differences in presentation, comorbidities, or perioperative variables. Multivariable Cox regression showed lower infection-free survival among patients with EAB (hazard ratio [HR], 2.4; 95% confidence interval [CI], 1.6-3.6; P < .001), polymicrobial infection (HR, 2.2; 95% CI, 1.4-3.5; P = .001), methicillin-resistant Staphylococcus aureus infection (HR, 1.7; 95% CI, 1.1-2.7; P = .02), as well as the protective effect of omental/muscle flap coverage (HR, 0.59; 95% CI, 0.37-0.92; P = .02). CONCLUSIONS: After complete resection of AGI, perioperative mortality is 16% and median overall survival is 5.8 years. EAB is associated with nearly a two and one-half-fold higher reinfection/mortality compared with ISB. Omental and/or muscle flap coverage of the repair appear protective.

RESUMO

BACKGROUND: A simple hysterectomy is considered the definitive treatment modality for cervical intraepithelial neoplasia (CIN). However, it is associated with recurrence of vaginal intraepithelial neoplasia (VAIN) of up to 7.4%. We sought to determine recurrence rates of VAIN, in women living with HIV (WLWH) and non-infected women. METHODS: This was a descriptive retrospective review of patients who received a simple hysterectomy for CIN between January 2015 and December 2017 in Pietermaritzburg. RESULTS: Fifty-eight files were reviewed. Forty-two (72.4%) WLWH were seen; amongst those, 76.2% were virally suppressed. Abnormal vault cytology was only seen in patients with CIN grades 2 and 3. The recurrence rates for high-grade squamous intraepithelial lesion (HSIL) were 6.1% and 5.0% at 6 and 12 months, respectively. Human immunodeficiency virus co-infection was associated with 26.2% versus 13.3% of abnormal vault cytology compared to the HIV-negative counterparts (p = 0.164). Virologically suppressed patients had more abnormal cytology (28.1% vs. 0%) compared to the unsuppressed patients. There was a 17.2% and 65.5% loss- to follow-up rates at 6 and 12 months, respectively. Recurrence of premalignant lesions was noted amongst those who had the abdominal approach. CONCLUSION: The recurrence rates were comparable to the previous literature. A 6-month cytology follow-up showed no added benefit. Human immunodeficiency virus co-infection didn't show a statistical significance on the recurrence rates; however, more structured studies are required to address this. Primary health care-based post operative surveillance can be a solution to address high loss to follow-up.

RESUMO

BACKGROUND: Open wound management in prosthetic joint infection (PJI) patients has been used in problematic dehisced wounds hoping to stimulate granulation tissue and closure. However, infections that start as a monomicrobial PJI can become polymicrobial with resultant worse outcomes following open wound management. This study assessed the relationship between open wound management and the development of polymicrobial periprosthetic joint infections. METHODS: We reviewed patients referred with a synovial cutaneous fistula. Patients with an open wound measuring less than 2 cm and less than two weeks of open wound management were excluded. Variables included original organisms cultured, type and length of open wound management, and organisms cultured at the time of revision infection surgery. RESULTS: Of the 65 patients with a previous monomicrobial infection treated with open wound management, 22/65 (34%) progressed to a polymicrobial infection. Thirty (46%) wounds were packed open with gauze, 20 (31%) were managed with negative pressure wound therapy, and 15 (23%) had surface dressings only. Of the 22 patients who converted to a polymicrobial infection, only 10 (45%) were infection free at follow-up. In contrast, 30 of 43 patients (70%) whose infections remained monomicrobial were infection free at follow-up. CONCLUSION: Open wound management can lead to conversion from a monomicrobial to a polymicrobial PJI, a rate of 34% in this series. Open prosthetic wound management should be discontinued for a fear of converting a monomicrobial infection to a difficult to treat polymicrobial infection. Surgeons must be prudent in the use of open wound management. LEVEL OF EVIDENCE: Level IV, Retrospective Case Series.

RESUMO

Despite the plethora of evidence in support of the use of structural osseous autograft in lumbar spondylodiscitis, attention has recently been turned to the addition of synthetic materials such as polyetheretherketone (PEEK) to restore anterior vertebral column support.From January 2015 to April 2017, 7 patients with lumbar polymicrobial spondylodiscitis were surgically treated with a minimally invasive oblique retroperitoneal approach to the infected focus. The patients underwent a standard lateral minimally invasive oblique retroperitoneal approach using direct lateral interbody fusion system. The PEEK cages were loaded with autologous bone graft. All the patients underwent posterior fixation with percutaneous pedicle screw instrumentation. Lumbar function was measured using Oswestry Disability Index, and pain was measured with visual analog scale. Fusion and subsidence were also recorded.The study included 5 female and 2 male patients. The median age was 58.9 years. The duration of follow-up was 31.8 ±â€Š6.1 months (range: 24-47). All patients recovered from the infection without relapse within 24-month follow-up. Visual analog scale significantly declined from 7.57 ±â€Š0.53 before surgery to 1.57 ±â€Š0.53 at 12-month follow-up. Mean Oswestry Disability Index decreased from 72.14 ±â€Š6.82 before surgery to 22.28 ±â€Š2.13 after surgery. All patients had solid fusion at 2-year follow-up. Fusion occurred at 6 to 15 months (mean 9.8 months).The specific use of PEEK cages in lumbar polymicrobial spondylodiscitis suggests reliable outcome in terms of clinical and imaging outcomes in our limited cases.

RESUMO

INTRODUCTION: Isolated metacarpal tuberculosis is rare in orthopedic surgery. In the case of poor efficacy of traditional treatment methods, such as debridement surgery and anti-tuberculosis treatment, it is necessary to consider whether there is a special type of infection. We describe a case of metacarpal tuberculosis with Nocardia infection in a patient. PATIENT CONCERNS: A 65-year-old male patient who suffered from pain and dysfunction lasted for 6 years. DIAGNOSES: Confirmation of the diagnosis was finally achieved by isolation of M tuberculosis and Nocardia actinomycetes from bone specimens. INTERVENTIONS: The patient underwent debridement surgery, Masquelet technique was used during the operation, and oral antibiotics were combined after surgery. OUTCOMES: Bone graft surgery was performed 6 weeks after the first surgery. We followed up on bone healing at 1 and 3 months postoperatively. CONCLUSION: Tissue-specific necrosis usually occurs in particular types of infections such as tuberculosis, which limits the spread of antibiotics. Masquelet technique seems to bring new options to solve this problem. The performance of Nocardia infection is similar to that of tuberculosis infection, so it is difficult to identify clinically. Therefore, for cases where tuberculosis is suspected, and anti-tuberculosis treatment is ineffective, the possibility of Nocardia infection needs to be considered.

RESUMO

The case is presented of a 62 year-old woman with a rapid, progressive bilateral decrease in visual acuity and panuveitis with orbital cellulitis. She was also in poor general condition, with emesis and fever. Septicaemia due to Klebsiella pneumoniae and bilateral endogenous panophthalmitis were diagnosed. The ocular infection quickly progressed to sclerokeratitis and bilateral perforation despite broad spectrum systemic antibiotic management, and eventually the patient required bilateral enucleation. Microbiological cultures of the surgical pieces identified Klebsiella pneumoniae and Candida magnoliae. To our knowledge, this is the third published case that required bilateral enucleation or evisceration due to endogenous panophthalmitis, and the first case of endogenous ocular infection caused by Candida magnoliae.

RESUMO

BACKGROUND: Polymicrobial hip arthroplasty infections are a subset of periprosthetic joint infection (PJI) with distinct challenges representing 10%-47% of PJI. METHODS: Records were reviewed from all PJIs involving partial or total hip arthroplasty with positive hip cultures between 2005 and 2015 in order to determine baseline characteristics and outcomes including treatment success, surgeries for infection, and days in hospital for infection. Analysis was restricted to patients who had at least 2 years of follow-up after their final surgery or hospitalization for infection. Factors with P-value less than .05 in univariate outcomes analysis were included in multivariable models. RESULTS: After multivariable analysis, 28 of 95 hip arthroplasty PJIs which were polymicrobial were associated with significantly lower treatment success, more surgery, and longer hospitalizations compared to PJIs which were not polymicrobial. Patients diagnosed with polymicrobial infection later in treatment (4 of 28) had the lowest treatment success rate, underwent the most surgery, and spent the longest time in hospital. CONCLUSION: Polymicrobial periprosthetic hip infection is a particularly devastating complication of hip arthroplasty associated with decreased likelihood of treatment success, increased surgery for infection, and greater time in hospital. Patients with late polymicrobial infection had the worst outcomes. This investigation further characterizes the natural history of periprosthetic hip infections with more than one infectious organism. Patients who present with a subsequent polymicrobial infection should be educated that they have a particularly difficult treatment course and treatment success may not be possible.

RESUMO

Morocco is an endemic area for both hydatid cyst and tuberculosis (TB). The co-occurrence of these two diseases in lung is unusual, especially when localized in the same area. We describe the case of a patient with pulmonary hydatid cyst associated with tuberculosis infection where the diagnosis was unknown prior to surgery because TB tests were negative. The surgical resection was very difficult because of inflammation in the surrounding tissue and its fragility. However, the postoperative course was uneventful. The goal of this case report is to keep in mind that such co-infection is possible especially in endemic countries.

RESUMO

BACKGROUND: In this study, we retrospectively analyzed the recurrence of hepatitis B virus (HBV) and hepatitis D virus (HDV) infection after liver transplantation for HBV and HBV+HDV co-infection. METHODS: Data from patients infected with HBV and HBV+HDV who underwent liver transplantation between March 2003 and June 2013 at the Liver Transplantation Institute of Inonu University were analyzed retrospectively. A total of 255 patients were included in the study. Group 1 (n = 127) comprised patients who underwent liver transplantation because of HBV, and group 2 (n = 128) comprised patients who underwent liver transplantation because of HBV+HDV. A positive HDV antibody serologic test result was taken to indicate liver disease caused by HBV+HDV. RESULTS: Thirteen of 255 were positive for the HBs Ag (5.1%). Nine (7.1%) and 4 (3.1%) patients were positive for the HBs Ag in groups 1 and 2, respectively (7.1%); the difference was not significant (P = .150). No HDV recurrence was detected in either group. The average time to HBs Ag seroconversion in 13 patients was 7.8 months after surgery (6.34 months in group 1 and 11.1 months in group 2). CONCLUSIONS: In our study, recurrence rate of HBV after liver transplantation is not statistically different than the recurrence rate of HBV+HDV co-infection. A low recurrence rate was achieved by the prophylaxis protocol in use at our center. There is no standard protocol for prevention of HBV and HDV recurrence; therefore, we need new studies.

RESUMO

We previously reported that progression of liver cirrhosis is quicker and survival is dismal in patients with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) coinfection, especially when acquired in childhood through contaminated blood products. Recently, we performed the first deceased donor liver transplantation (DDLT) for an HIV/HCV-coinfected hemophilic patient in Japan. A 40-year-old man was referred to our hospital for liver transplantation. Regular DDLT was performed using the piggyback technique with a full-sized liver graft. Cold ischemia time was 465 min, and the graft liver weighed 1,590 g. The antiretroviral therapy (ART) was switched from darunavir/ritonavir to raltegravir before the transplant for flexible usage of calcineurin inhibitors postoperatively; tenofovir was used as the baseline treatment. The postoperative course was uneventful, and the patient was discharged home on day 43. He started receiving anti-HCV treatment on day 110 with pegylated interferon, ribavirin, and simeprevir after the DDLT. Herein, we report the first case of DDLT in Japan. Meticulous management of ART and clotting factors could lead to the success of DDLT.

RESUMO

Liver retransplantation is performed in HIV-infected patients, although its outcome is not well known. In an international cohort study (eight countries), 37 (6%; 32 coinfected with hepatitis C virus [HCV] and five with hepatitis B virus [HBV]) of 600 HIV-infected patients who had undergone liver transplant were retransplanted. The main indications for retransplantation were vascular complications (35%), primary graft nonfunction (22%), rejection (19%), and HCV recurrence (13%). Overall, 19 patients (51%) died after retransplantation. Survival at 1, 3, and 5 years was 56%, 51%, and 51%, respectively. Among patients with HCV coinfection, HCV RNA replication status at retransplantation was the only significant prognostic factor. Patients with undetectable versus detectable HCV RNA had a survival probability of 80% versus 39% at 1 year and 80% versus 30% at 3 and 5 years (p = 0.025). Recurrence of hepatitis C was the main cause of death in the latter. Patients with HBV coinfection had survival of 80% at 1, 3, and 5 years after retransplantation. HIV infection was adequately controlled with antiretroviral therapy. In conclusion, liver retransplantation is an acceptable option for HIV-infected patients with HBV or HCV coinfection but undetectable HCV RNA. Retransplantation in patients with HCV replication should be reassessed prospectively in the era of new direct antiviral agents.

RESUMO

Co-infections of cystic echinococcosis (CE) and HIV/AIDS is rare. We report four CE cases that were HIV positive. Three out of the four patients underwent a surgical operation to remove the hydatid cysts in their livers. The operation confirmed that in two of the cases their cysts had ruptured. These patients were given 3 months of albendazole after the operation. Follow-up showed they were remarkably improved in term of their health, although they were still HIV antibody positive 6 months after surgical treatment. Interestingly, the treatment remarkably increased their CD4+ cell population. We showed that surgery is suitable for treating hepatic cystic echinococcosis with HIV/AIDS co-infection.

RESUMO

CONTEXT: Orthotopic liver transplantation (OLT) is the treatment of choice for end-stage liver disease. Cirrhosis due to hepatitis C infection is the leading indication for liver transplantation worldwide. However, patients who are given transplants because of viral liver diseases often present clinical coinfections, including hepatitis B together with hepatitis D. Currently, different strategies exist for patient management before and after liver transplantation, and these are based on different protocols developed by the specialized transplantation centers. CASE REPORT: We present a rare case of a 58-year-old man with chronic hepatitis B, C and D coinfection. The patient developed cirrhosis and hepatocellular carcinoma. His treatment comprised antiviral therapy for the three viruses and OLT. The patient's outcome was satisfactory. CONCLUSION: OLT, in association with antiviral therapy using entecavir, which was administered before and after transplantation, was effective for sustained clearance of the hepatitis B and D viruses. A recurrence of hepatitis C infection after transplantation responded successfully to standard treatment comprising peginterferon alfa-2A and ribavirin.


CONTEXTO: O transplante ortotópico de fígado (TOF) é o tratamento de escolha em pacientes com doença hepática terminal. A cirrose por hepatite C é a principal indicação de transplante hepático no mundo. No entanto, pacientes transplantados por hepatopatias virais frequentemente apresentam coinfecções, como hepatite B associada a hepatite D. Atualmente, existem diferentes estratégias de manejo em pacientes pré e pós-transplantados conforme diferentes protocolos de conduta de serviços especializados em transplante. RELATO DE CASO: Apresentamos o raro caso de um homem de 58 anos diagnosticado com as hepatites crônicas B, C e D. O paciente evoluiu com cirrose e carcinoma hepatocelular. O tratamento consistiu de terapia antiviral para os três vírus e de transplante ortotópico de fígado. O desfecho do paciente foi satisfatório. CONCLUSÃO: O transplante ortotópico de fígado, associado à terapia antiviral com entecavir antes e após o procedimento, foi eficaz na depuração sustentada dos vírus B e D. A recidiva do vírus C após o transplante respondeu com sucesso ao tratamento padrão com alfapeginterferon 2A e ribavirina.

RESUMO

Liver disease is a leading cause of mortality among HIV-infected persons in the highly active anti-retroviral therapy (HAART) era. Hepatitis C Virus (HCV) co-infection is prevalent in, and worsened by HIV; consequently many co-infected persons require liver transplantation (LT). Despite the need, post-LT outcomes are poor in co-infection. We examined predictors of outcomes post-LT. Immunologic biomarkers of immune activation, microbial translocation, and Th1/Th2 skewing were measured pre-LT in participants enrolled in a cohort of HIV infected persons requiring solid organ transplant (HIVTR). Predictive biomarkers were analyzed in Cox-proportional hazards models; multivariate models included known predictors of outcome and biomarkers from univariate analyses. Sixty-nine HIV-HCV co-infected persons with available pre-LT samples were tested: median (IQR) CD4+ T-cell count was 286 (210-429) cells mm-3; 6 (9%) had detectable HIV RNA. Median (IQR) follow-up was 2.1 (0.7-4.0) years, 29 (42%) people died, 35 (51%) had graft loss, 22 (32%) were treated for acute rejection, and 14 (20%) had severe recurrent HCV. In multivariate models, sCD14 levels were significantly lower in persons with graft loss post-LT (HR 0.10 [95%CI 0.02-0.68]). IL-10 levels were higher in persons with rejection (HR 2.10 [95%CI 1.01-4.34]). No markers predicted severe recurrent HCV. Monocyte activation pre-LT may be mechanistically linked to graft health in HIV-HCV co-infection.

RESUMO

Liver transplantation is increasingly performed in selected HIV-infected patients in most developed countries, with excellent results reported in patients with liver diseases unrelated to HCV. In contrast, survival in HCV/HIV-coinfected liver recipients is poorer than in HCV-monoinfected patients, due to more aggressive recurrence of HCV and consequent graft loss and death. Results from American, French, and Spanish cohort studies showed a 5-year survival rate of only 50-55%. Therefore, it is debated whether liver transplantation should be offered to HCV/HIV-coinfected patients. Studies have shown that the variables more consistently associated with poor outcome are: (1) the use of old or HCV-positive donors, (2) dual liver-kidney transplantation, (3) recipients with very low body mass index and (4) less site experience. However, the most effective factor influencing transplantation outcome is the successful treatment of HCV recurrence with anti-HCV. Survival is 80% in patients whose HCV infection resolves. Unfortunately, the rates of sustained virological response with pegylated-interferon plus ribavirin in coinfected recipients are low, particularly for genotype 1 (only 10%). Here we present a non-systematic review of the literature based on our own experience in different liver transplant scenarios. This review covers selection criteria in HIV-infected patients, pre- and post-LT management, donor selection, anti-HCV treatment, drug interactions with antiretrovirals and anti-HCV direct antiviral agents, hepatocellular carcinoma, and liver retransplantation. Recommendations are rated. Finally, we explain how the introduction of new effective and more tolerable direct antiviral agents may improve significantly the outcome of HCV/HIV-coinfected liver recipients.

RESUMO

INTRODUCTION: Co-infected HIV and hepatitis subjects are candidates for a liver transplantation because of progressive liver disease. Chronic liver disease, co-infected or not, requires assessment of respiratory function before liver transplantation. The respiratory evaluation of these 2 groups compared with healthy individuals can define deficits, and this can impair a full recovery after transplant surgery. OBJECTIVE: This study sought to compare the respiratory profile in co-infected patients with chronic liver disease who are candidates for liver transplantation with that of healthy subjects. METHODS: Through respiratory evaluation of flows and lung volumes (spirometry), muscle activity (surface electromyography), and maximum pressure (manovacuometer), 250 people were distributed into 3 groups: 14 patients with HIV and liver disease, 65 healthy subjects, and 171 patients with chronic liver disease. The mean age (years) was respectively 47.5 ± 6.2, 48.3 ± 14.1, and 52.9 ± 8.5. The average body mass index (kg/m(2)) of the groups was 24.6 ± 4.5, 26.0 ± 3.2, and 28.5 ± 5.3, respectively. RESULTS: There was a statistical difference among the groups in the root means square (RMS) rectus abdominis (µV) (P = .0016), RMS diaphragm (µV) (P = .0001), maximal inspiratory pressure (cmH2O) (P = .001), forced exhaled volume at the end of first second (%) (P = .002), and maximal mid expiratory flow 25% to 75% (%) (P = .0001) for the Kruskal-Wallis test. The multivariate analysis among the groups showed that the RMS diaphragm had a tendency to discriminate the co-infected subjects. CONCLUSIONS: The co-infected HIV group showed a muscle deficit of diaphragm and rectus abdominis activity, and the liver disease group showed lower indexes in volumes and respiratory flows.
