RESUMO

The objective of our work was to develop deep learning methods for extracting and normalizing patient-reported free-text side effects in a cancer chemotherapy side effect remote monitoring web application. The F-measure was 0.79 for the medical concept extraction model and 0.85 for the negation extraction model (Bi-LSTM-CRF). The next step was the normalization. Of the 1040 unique concepts in the dataset, 62, 3% scored 1 (corresponding to a perfect match with an UMLS CUI). These methods need to be improved to allow their integration into home telemonitoring devices for automatic notification of the hospital oncologists.

RESUMO

PURPOSE: Numerous studies, including our previous work with lemon juice, have reported that low-pH meals reduce the glycemic response to starchy foods. However, the underlying mechanism is not yet understood. Tea, for its polyphenol content, has also been investigated. The main objective of this research was to concurrently study gastric emptying, appetite perceptions and glycemic responses to bread consumed with water, tea, or lemon juice. METHODS: In this randomized, crossover intervention, ten participants consumed equal portions of bread (100 g) with 250 mL of water, water-diluted lemon juice, or black tea at breakfast. Gastric volumes, blood glucose concentrations and appetite perceptions were alternately assessed over 180 min using magnetic resonance imaging, the finger-prick method and visual analogue scales, respectively. RESULTS: Compared to water, lemon juice led to a 1.5 fold increase of the volume of gastric contents, 30 min after the meal (454.0 ± 18.6 vs. 298.4 ± 19.5 mL, [Formula: see text] ± SEM P < 0.00001). Gastric emptying was also 1.5 times faster (P < 0.01). Conversely, lemon juice elicited a lower glycemic response than water (blood glucose concentrations at t = 55 min were 35% lower, P = 0.039). Tea had no effect. Changes in appetite perceptions and gastric volumes correlated well, but with no significant differences between the meals. CONCLUSIONS: Lemon juice lowered the glycemic response and increased both gastric secretions and emptying rate. The results are compatible with the hypothesis that the reduction of the glycemic response is mainly due to the interruption of starch hydrolysis via the acid-inhibition of salivary α-amylase. TRIAL REGISTRATION NUMBER: NCT03265392, August 29, 2017.

RESUMO

PURPOSE: The inhibition of enzymes that hydrolyze starch during digestion could constitute an opportunity to slow down the release, and ultimately the uptake, of starch-derived glucose. Simple dietary approaches consisting in pairing starch-rich foods with beverages that have the capacity to inhibit such enzymes could be an effective and easily implementable strategy. The objective of this work was to test the impact of black tea and lemon juice on the glycemic response to bread and subsequent energy intake in healthy adults. METHODS: A randomized crossover study was conducted with equal portions of bread (100 g) and 250 ml of water, black tea or lemon juice. Capillary blood glucose concentrations were monitored during 180 min using the finger-prick method. Ad libitum energy intake was assessed 3 h later. RESULTS: Tea had no effect on the glycemic response. Lemon juice significantly lowered the mean blood glucose concentration peak by 30% (p < 0.01) and delayed it more than 35 min (78 vs. 41 min with water, p < 0.0001). None of the tested beverages had an effect on ad libitum energy intake. CONCLUSION: These results are in agreement with previous in vitro studies showing that lowering the pH of a meal can slow down starch digestion through premature inhibition of salivary α-amylase. Furthermore, the effect of lemon juice was similar to what has been repeatedly observed with vinegar and other acidic foods. Including acidic beverages or foods in starchy meals thus appears to be a simple and effective strategy to reduce their glycemic impact.

RESUMO

BACKGROUND: An increased risk of cardiovascular disease (CVD) was reported in patients coinfected with human immunodeficiency virus (HIV) and hepatitis C virus (HCV), without identifying factors associated with atherosclerotic CVD (ASCVD) events. METHODS: HIV-HCV coinfected patients were enrolled in the Agence Nationale de Recherches sur le Sida et les hépatites virales (ANRS) CO13 HEPAVIH nationwide cohort. Primary outcome was total ASCVD events. Secondary outcomes were coronary and/or cerebral ASCVD events, and peripheral artery disease (PAD) ASCVD events. Incidences were estimated using the Aalen-Johansen method. Factors associated with ASCVD were identified using cause-specific Cox proportional hazards models. RESULTS: At baseline, median age of the study population (N = 1213) was 45.4 (interquartile range [IQR] 42.1-49.0) years and 70.3% were men. After a median follow-up of 5.1 (IQR 3.9-7.0) years, the incidence was 6.98 (95% confidence interval [CI], 5.19-9.38) per 1000 person-years for total ASCVD events, 4.01 (2.78-6.00) for coronary and/or cerebral events, and 3.17 (2.05-4.92) for PAD ASCVD events. Aging (hazard ratio [HR] 1.06; 95% CI, 1.01-1.12), prior CVD (HR 8.48; 95% CI, 3.14-22.91), high total cholesterol (HR 1.43; 95% CI, 1.11-1.83), high-density lipoprotein cholesterol (HR 0.22; 95% CI, 0.08-0.63), statin use (HR 3.31; 95% CI, 1.31-8.38), and high alcohol intake (HR 3.18; 95% CI, 1.35-7.52) were independently associated with total ASCVD events, whereas undetectable baseline viral load (HR 0.41, 95% CI, 0.18-0.96) was associated with coronary and/or cerebral events. CONCLUSIONS: HIV-HCV coinfected patients experienced a high incidence of ASCVD events. Some traditional cardiovascular risk factors were the main determinants of ASCVD. Controlling cholesterol abnormalities and maintaining undetectable HIV RNA are essential to control cardiovascular risk.

RESUMO

OBJECTIVE: Chronic hepatitis C virus (HCV) and hepatitis B virus (HBV) infections are associated with increased risks of lymphomas in the non-HIV setting. Their impacts on HIV-associated lymphomas deserved further studies in the modern combined antiretroviral therapy (cART) era. DESIGN: We evaluated the associations between HCV, HBV and HIV-related lymphomas in the Lymphovir-ANRS-CO16 cohort. METHODS: Prevalence of HCV seropositivity and chronic HBV infections were compared with those observed in the French Hospital Database on HIV (FHDH-ANRS-CO4). RESULTS: Between 2008 and 2015, 179 patients with HIV-related lymphomas from 32 French hospitals were enrolled, 69 had Hodgkin's lymphoma (39%), and 110 non-Hodgkin's lymphoma (NHL) (61%). The prevalence of HCV infection was higher in patients with NHL than in the FHDH-ANRS-CO4 [26 versus 14%, odd ratio (OR): 2.15; 95% confidence interval (1.35-3.32)] whereas there was no association between Hodgkin's lymphoma and chronic HCV infection. Chronic HBV infection was not associated with NHL in our cohort with a prevalence of 5 versus 7% in FHDH-ANRS-CO4 but tended to be associated with Hodgkin's lymphoma [prevalence of 14%, OR: 2.16 (0.98-4.27)]. Chronic HCV infection tended to pejoratively impact 2-year overall survival in patients with NHL: 72% [57%, 91%] versus 82% [74%, 91%], hazard ratio: 2.14 [0.95-4.84]. In contrast, chronic HBV infection did not correlate with outcome. CONCLUSION: In the modern cART era, chronic HCV infection is associated with an increased risk of NHL in PLWHIV and tends to pejoratively impact overall survival. HBV infection is not associated with the risk of NHL but with a borderline increase of Hodgkin's lymphoma risk.

RESUMO

The prognostic value of cell of origin (COO) classification and BCL2 expression is not well established in diffuse large B-cell lymphoma (DLBCL) patients with human immunodeficiency virus (HIV) infection in the recent era. Phenotypic patterns were determined by immunohistochemistry (IHC) of pathological samples from patients with HIV-associated DLBCL prospectively enrolled in the French AIDS and Viral Hepatitis CO16 Lymphovir cohort between 2008 and 2015. Molecular subgroup classification into germinal centre B-cell (GCB) and non-GCB subtypes was determined using the Hans algorithm. Among 52 samples of systemic DLBCL subjected to centralized pathological analysis, 25 of the 42 tested for BCL2 expression were positive. Samples were further classified into GCB (n = 19) and non-GCB (n = 16) subtypes and 17 remained unclassified. In multivariable analysis, BCL2 expression was an independent pejorative prognostic biomarker [4-year progression-free survival (PFS): 52% for BCL2+ vs. 88% for BCL2- , P = 0·02] and tended to reduce 4-year overall survival (OS) (63% for BCL2+ vs. 88% for BCL2- , P = 0·06). The difference between CGB and non-GCB subtypes on PFS and OS did not reach significance (4-year PFS: 79% for GCB vs. 53% for non-GCB, P = 0·24 and 4-year OS: 78% for GCB vs. 69% for non-GCB, P = 0·34). BCL2 expression determined by IHC is an independent pejorative prognostic biomarker in HIV-associated DLBCL in the recent era. This supports the investigation of new therapeutic strategies in patients with BCL2 expression.

RESUMO

Barriers to achieve sustained HIV virological suppression on antiretroviral therapy (ART) jeopardize the success of the 90:90:90 UNAIDS initiative which aims to end the HIV/AIDS epidemic. In France, where access to ART is free and universally available, we analyze the way in which social determinants of health (i.e. cultural, environmental) and economic factors might influence virological outcomes. A cross-sectional study was performed in two hospitals located in Paris area. All consecutive people living with HIV (PLHIV) on ART for at least 6 months attending the outpatient clinics between 01/05/2013 and 31/10/2014 answered an individual score of deprivation, EPICES, retrieving information on health insurance status, economic status, family support and leisure activity. This score varies from 0 to 100 with deprivation state defined above 30.17. Factors associated with HIV viral load >50 copies/ml were assessed by logistic regression modeling with a backward stepwise selection to select the final multivariable model. Sensitivity analyses were performed using two other thresholds for virological non-suppression (100 or 200 copies/ml). Overall, 475 PLHIV were included (53% male, median age 47 years, 66% not born in France mainly in a sub-Saharan African country). Half of French natives and 85% of migrants were classified as deprived. Median duration on ART was 9.7 years with virological suppression in 95.2% of non-deprived participants and in 83.5% of deprived ones (p = 0.001). The final multivariable model retained ART tiredness, younger age, a previous AIDS event and social deprivation (adjusted Odds Ratio, 2.9; 95%CI, 1.2-7.0) as determinants of virological non-suppression but not migration in itself. When using separate components of EPICES score, reporting economic difficulties and non-homeownership were associated with virological non-suppression. In addition to interventions focusing on cultural aspects of migration, social interventions are needed to help people with social vulnerability to obtain sustained responses on ART.

RESUMO

OBJECTIVE: Non-Hodgkin's lymphoma (NHL) remains among the most frequent malignancies in persons living with HIV (PLWHIV). Survival among patients with HIV-associated diffuse large B-cell lymphoma (DLBCL), the most frequent NHL subtype, has improved markedly in recent years. We aimed to analyze characteristics and outcomes of DLBCL in HIV-infected patients in the era of modern combined antiretroviral therapy (cART). DESIGN: PLWHIV with lymphoma were prospectively enrolled in the French ANRS-CO16 Lymphovir cohort between 2008 and 2015. We compared the patients treated with R-CHOP) (rituximab, cyclophosphamide, daunorubicin, vin-cristine, prednisolone) with HIV-negative DLBCL patients enrolled simultaneously in the R-CHOP arms of Lymphoma Study Association trials. RESULTS: Among 110 PLWHIV with NHL, 52 (47%) had systemic DLBCL. These 52 cases had frequent extranodal disease (81%), poor performance status (35%) and advanced age-adjusted international prognostic index (aaIPI) (58%), and were mainly treated with R-CHOP (n = 44, 85%). Their median CD4 T-cell count was 233 cells/µl, and 79% of patients were on cART. The 2-year overall and progression-free survival rates were both 75% (95% confidence interval: 64%, 88%). Factors associated with progression or death in univariate analysis were poor performance status [hazard ratio: 3.3 (1.2, 8.9)], more than one extranodal site [hazard ratio: 3.4 (1.1, 10.5)] and an advanced aaIPI [hazard ratio: 3.7 (1.0, 13.1)]. Progression-free survival after R-CHOP therapy did not differ from that of the HIV-negative counterparts (P = 0.11). CONCLUSION: In the recent cART era, despite frequent high-risk features, the 2-year overall survival of HIV-DLBCL patients reaches 75%. Outcomes after R-CHOP therapy are similar to those of HIV-negative patients with similar aaIPI.

RESUMO

BACKGROUND AND AIMS: Few data exist on changes to substance use patterns before and after hepatitis C virus (HCV) treatment. We used longitudinal data of HIV-HCV co-infected individuals to examine whether receiving pegylated interferon (Peg-IFN)-based therapy irrespective of HCV clearance could modify tobacco, cannabis and alcohol use. DESIGN: A prospective cohort of HIV-HCV co-infected individuals was enrolled from 2006. Participants' clinical data were retrieved from medical records and socio-demographic and behavioural characteristics were collected by yearly self-administered questionnaires. SETTING: Data were collected across 17 hospitals in France. PARTICIPANTS: All HIV-HCV co-infected patients who initiated HCV treatment during follow-up and answered items regarding substance use in at least one yearly questionnaire (258 patients, 671 visits). INTERVENTION: HCV treatment consisted of Peg-IFN-based regimens. MEASUREMENTS: Four time-varying outcomes: hazardous alcohol use (Alcohol Use Disorders Identification Test-C > 3/4 for women/men), number of alcohol units/month, binge drinking, cannabis and tobacco use. Mixed models assessed the effect of HCV treatment status (not yet treated, treated and HCV-cleared, treated and HCV-chronic) on each outcome. FINDINGS: A significant decrease (more than 60% reduction) in both hazardous alcohol use and binge drinking and a reduction of 10 alcohol units/month was observed after HCV treatment (irrespective of HCV clearance). No significant effect of HCV treatment status was found on tobacco use and regular cannabis use, but HCV 'clearers' reported less non-regular use of cannabis. CONCLUSIONS: Hepatitis C virus (HCV) treatment appears to help HIV-HCV co-infected patients reduce alcohol use.

RESUMO

Lenalidomide, an oral immunomodulating agent, has shown promising activity in HIV-infected individuals with Kaposi's sarcoma (KS). This single-arm, multicenter, open-label, Gehan's two-stage phase II trial evaluated the efficacy and safety of lenalidomide in HIV-infected patients with progressive KS despite previous chemotherapy (NCT01282047, ANRS 154 Lenakap trial). The primary endpoint was the rate of partial response (PR) or complete response (CR) at week 24, evaluated by both the study investigators and the patients using the Physical Global Assessment (PGA). AIDS Clinical Trials Group (ACTG) criteria for KS treatment evaluation were used as a secondary endpoint. The data and safety monitoring board recommended that enrollments be halted on April 24, 2013, because of lack of responses. We enrolled 12 antiretroviral-treated HIV-infected men with progressive KS despite previous chemotherapy. Their HIV plasma viral load was <50 copies/ml and their median CD4 cell count 444/mm3. One patient stopped taking lenalidomide because of hives at week 1 and a second patient died at week 7. The remaining 10 patients were assessable at week 24, when none had PGA-defined CR or PR and one had ACTG-defined PR. There were no additional PGA responses at week 48, but an additional three patients had ACTG responses, for a total of four patients with ACTG PR at week 48 (40%; 95% confidence interval: 12.2-73.8). Fourteen grade 3-4 adverse events were considered at least possibly related to lenalidomide during a total of 101 cycles. Lenalidomide was well tolerated in antiretroviral experienced patients with progressive KS previously treated with chemotherapy. The ACTG-defined response rate at week 48 was 40%, while it was 0% using PGA criteria.

RESUMO

BACKGROUND: Human immunodeficiency virus (HIV) infection is associated with a high risk of classical Hodgkin's lymphoma (cHL) in the combined antiretroviral therapy (cART) era. METHODS: We analyzed the characteristics and outcome of HIV-associated cHL diagnosed in the modern cART era. The French ANRS-CO16 Lymphovir cohort enrolled 159 HIV-positive patients with lymphoma, including 68 (43%) with cHL. HIV-HL patients were compared with a series of non-HV-infected patients consecutively diagnosed with HL. RESULTS: Most patients (76%) had Ann-Arbor stages III-IV and 96% of patients were treated with ABVD. At diagnosis, median CD4 T-cell count was 387/µL and 94% of patients were treated with cART. All patients received cART after diagnosis. Five patients died from early progression (n = 2), sepsis (1) or after relapse (2). Two additional patients relapsed during follow-up. Two-year overall and progression free survivals (PFS) were 94% [95% CI, 89%, 100%] and 89% [82%, 97%], respectively. The only factor associated with progression or death was age with a relative risk of 8.1 [1.0; 67.0] above 45 years. The PFS of Lymphovir patients appeared similar to PFS of HIV-negative patients, 86% [82%, 90%], but patients with HIV infection displayed higher risk features than HIV-negative patients. CONCLUSIONS: Although high-risk features still predominate in HIV-HL, the prognosis of these patients, treated with cART and mainly ABVD, has markedly improved in the modern cART era and is now similar to non-HIV-infected patients.

RESUMO

In Schnitzler syndrome, which is mostly diagnosed with a low and asymptomatic monoclonal peak, anakinra has always exhibited a complete but only transient control of the auto-inflammatory signs, which are induced by interleukin (IL)-1 auto-activation. We focused on the treatment of a case of Schnitzler syndrome with moderate macroglobulinemia peak. Anakinra failed to improve the severe inflammatory anaemia and the dysglobulinemia, but rituximab-dexamethasone-cyclophosphamide chemotherapy alone allowed a complete response. The correlation between the clinical, pro-inflammatory cytokines and dysglobulinemia complete controls with chemotherapy proves the following: (1) the dual action of this treatment in both the auto-inflammatory and dysglobulinemia components of the syndrome and (2) a different but entangled cytokine network in the pathogenesis of the auto-inflammatory and dysglobulinemia components of the syndrome.

RESUMO

While the International Prognostic Index is commonly used to predict outcomes in immunocompetent patients with aggressive B-cell non-Hodgkin lymphomas, HIV-infection is an important competing risk for death in patients with AIDS-related lymphomas. We investigated whether a newly created prognostic score (AIDS-related lymphoma International Prognostic Index) could better assess risk of death in patients with AIDS-related lymphomas. We randomly divided a dataset of 487 patients newly diagnosed with AIDS-related lymphomas and treated with rituximab-containing chemoimmunotherapy into a training (n=244) and validation (n=243) set. We examined the association of HIV-related and other known risk factors with overall survival in both sets independently. We defined a new score (AIDS-related lymphoma International Prognostic Index) by assigning weights to each significant predictor [age-adjusted International Prognostic Index, extranodal sites, HIV-score (composed of CD4 count, viral load, and prior history of AIDS)] with three risk categories similar to the age-adjusted International Prognostic Index (low, intermediate and high risk). We compared the prognostic value for overall survival between AIDS-related lymphoma International Prognostic Index and age-adjusted International Prognostic Index in the validation set and found that the AIDS-related lymphoma International Prognostic Index performed significantly better in predicting risk of death than the age-adjusted International Prognostic Index (P=0.004) and better discriminated risk of death between each risk category (P=0.015 vs. P=0.13). Twenty-eight percent of patients were defined as low risk by the ARL-IPI and had an estimated 5-year overall survival (OS) of 78% (52% intermediate risk, 5-year OS 60%; 20% high risk, 5-year OS 50%).

RESUMO

The French Hospital Database on HIV (FHDH) is a hospital-based multicentre open cohort with inclusions ongoing since 1989. The research objectives focus mainly on mid- and long-term clinical outcomes and therapeutic strategies, as well as severe AIDS and non-AIDS morbidities, and public health issues relative to HIV infection. FHDH also serves to describe HIV-infected patients receiving hospital care in France. FHDH includes data on more than 120,000 HIV-infected patients from 70 French general or university hospitals distributed throughout France. Patients are eligible for inclusion if they are infected by HIV-1 or HIV-2 and give their written informed consent. Standardized variables are collected at each outpatient visit or hospital admission during which a new clinical manifestation is diagnosed, a new treatment is prescribed or a change in biological markers is noted, and/or at least every 6 months. Since its inception, variables collected in FHDH include demographic characteristics, HIV-related biological markers, the date and type of AIDS and non AIDS-defining events, antiretroviral treatments and the date and causes of death, as reported in the medical records. Since 2005, data have also been collected on: co-infection with hepatitis B or C virus; alcohol and tobacco use; and non HIV-related biomarkers. Anyone can submit a research project by completing a standardized form available on the FHDH website (http://www.ccde.fr/_fold/fl-1385734776-429.pdf) or from the corresponding author, describing the context and objectives of the study. All projects are reviewed by the scientific committee.

RESUMO

Limited comparative data exist for the treatment of HIV-associated non-Hodgkin lymphoma. We analyzed pooled individual patient data for 1546 patients from 19 prospective clinical trials to assess treatment-specific factors (type of chemotherapy, rituximab, and concurrent combination antiretroviral [cART] use) and their influence on the outcomes complete response (CR), progression free survival (PFS), and overall survival (OS). In our analysis, rituximab was associated with a higher CR rate (odds ratio [OR] 2.89; P < .001), improved PFS (hazard ratio [HR] 0.50; P < .001), and OS (HR 0.51; P < .0001). Compared with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP), initial therapy with more dose-intense regimens resulted in better CR rates (ACVBP [doxorubicin, cyclophosphamide, vindesine, bleomycin and prednisolone]: OR 1.70; P < .04), PFS (ACVBP: HR 0.72; P = .049; "intensive regimens": HR 0.35; P < .001) and OS ("intensive regimens": HR 0.54; P < .001). Infusional etoposide, prednisone, infusional vincristine, infusional doxorubicin, and cyclophosphamide (EPOCH) was associated with significantly better OS in diffuse large B-cell lymphoma (HR 0.33; P = .03). Concurrent use of cART was associated with improved CR rates (OR 1.89; P = .005) and trended toward improved OS (HR 0.78; P = .07). These findings provide supporting evidence for current patterns of care where definitive evidence is unavailable.

RESUMO

PURPOSE: Bortezomib has previously demonstrated activity in indolent lymphomas including follicular lymphoma with response rate ranging from 13% to 56%. However, the optimal schedule of bortezomib remains to be investigated in follicular lymphoma. EXPERIMENTAL DESIGN: We conducted a randomised phase II study where patients with follicular lymphoma in relapse or refractory receive either bortezomib 1.5 mg/m(2) biweekly on days 1, 4, 8 and 11 of a 21-day cycle (arm A) or 1.6 mg/m(2) weekly on days 1, 8, 15 and 22 of a 35-day cycle (arm B). An interim analysis was planned after 15 fully evaluable patients randomised in each treatment arm. If only five subjects or fewer respond, the treatment arm was concluded to be ineffective and was closed to inclusion. RESULTS: Eighty-seven patients were included in the trial. Arm B was closed to inclusion after interim analysis. 15/50 patients (30%) in arm A and 8/37 patients (22%) in arm B achieved a response. Median duration of response was 16 and 15 months for arms A and B, respectively. Most drug-related adverse events (AEs) (all grades, all cycles) were mild. CONCLUSION: This study demonstrates tolerability and durable clinical benefit of bortezomib when given at 1.5 mg/m(2) biweekly. Despite a higher response rate in the biweekly arm, no major difference in patient's outcome was observed between the two arms in the final analysis.

RESUMO

We describe the striking and unexpected evolution of 10 patients with de novo multiple myeloma treated with novel-agent based induction therapy, who displayed a dissociated evolution characterised by an apparent good response contrasting with the concomitant development of aggressive non-secreting plasmocytomas immediately before, or just after, autologous stem cell transplantation. Patients did not respond to salvage therapies. Eight of them died from progression less than 12 months after diagnosis. This unusual evolution in the era of novel agents warrants further scrutiny.

RESUMO

OBJECTIVE: To determine whether incident AIDS-defining Kaposi sarcoma or Pneumocystis jiroveci pneumonia (PJP) is associated with combination antiretroviral therapy (cART) initiation. DESIGN: Compare risk for Kaposi sarcoma and PJP by time on cART and CD4 reconstitution. METHODS: : In the FHDH-ANRS CO4 cohort (N = 66 369), Kaposi sarcoma (N = 1811) and PJP (N = 1718) incidence rates were computed by demographic and HIV strata. Crude and adjusted relative risk (RR) with 95% confidence intervals (CIs) following cART initiation were calculated by Poisson regression with untreated patients during 1996-2009 as reference. CD4 cell counts were compared by Wilcoxon rank sum tests. RESULTS: The risk of Kaposi sarcoma was very high during months 1-3 on cART (N = 160, RRCrude 3.94, 95% CI 3.26-4.76), which was incompletely attenuated by adjustment for demographics and contemporaneous CD4 cell count (RRAdj 1.25, 95% CI 1.02-1.53). Corresponding PJP risk was minimally elevated (N = 84, RRCrude 1.80, 95% CI 1.42-2.30) and markedly reduced with adjustment on the same variables and PJP prophylaxis (RRAdj 0.52, CI 0.41-0.67). HIV load had no added effect. Median CD4 cell count at cART initiation was much lower in patients with incident Kaposi sarcoma (82 cells/µl) or PJP (61 cells/µl) within 3 months than in those who did not develop these conditions (>250 cells/µl). Notably, median CD4 cell count change was +44 cells/µl per month with incident Kaposi sarcoma within 3 months of cART initiation versus 0 cells/µl per month with incident PJP (P = 0.0003). CONCLUSION: Failure of CD4 cell count reconstitution during months 1-3 on cART fully accounted for incident PJP. In contrast, there were 1.6 additional Kaposi sarcoma cases per 1000 person-years during months 1-3 on cART, suggesting that immune reconstitution may contribute to the risk for AIDS-defining Kaposi sarcoma.

RESUMO

The risk of Hodgkin lymphoma (HL) is increased in patients infected with HIV-1. We studied the incidence and outcomes of HL, and compared CD4⁺ T-cell trajectories in HL patients and controls matched for duration of combination antiretroviral therapy (cART). A total of 40 168 adult HIV-1-infected patients (median age, 36 years; 70% male; median CD4 cell count, 234 cells/µL) from 16 European cohorts were observed during 159 133 person-years; 78 patients developed HL. The incidence was 49.0 (95% confidence interval [CI], 39.3-61.2) per 100,000 person-years, and similar on cART and not on cART (P = .96). The risk of HL declined as the most recent (time-updated) CD4 count increased: the adjusted hazard ratio comparing more than 350 with less than 50 cells/µL was 0.27 (95% CI, 0.08-0.86). Sixty-one HL cases diagnosed on cART were matched to 1652 controls: during the year before diagnosis, cases lost 98 CD4 cells (95% CI, -159 to -36 cells), whereas controls gained 35 cells (95% CI, 24-46 cells; P < .0001). The incidence of HL is not reduced by cART, and patients whose CD4 cell counts decline despite suppression of HIV-1 replication on cART may harbor HL.
