Corticosteroids as adjunctive therapy in patients with acute/subacute paracoccidioidomycosis presenting a severe paradoxical inflammatory reaction: Two case reports and literature review

While it is well-known that adjunctive corticosteroid use improves the outcome of moderate-to-severe Pneumocystis jirovecii pneumonia (PcP) in patients with human immunodeficiency virus (HIV), there are limited data on its efficacy in non-HIV-infected patients with PcP. Patients undergoing fiber-optic bronchoscopy with bronchoalveolar lavage for suspected PcP from January 2007 through December 2010 were reviewed retrospectively. We compared demographics, clinical characteristics, and outcomes in 88 non-HIV-infected patients with moderate-to-severe PcP with (n = 59) and without (n = 29) adjunctive corticosteroid use. Outcomes of PcP were assessed by respiratory failure and 30-day and 90-day all-cause mortality. Survival curves were analyzed by the Kaplan-Meier method and estimated by the log rank test. All-cause mortality of moderate-to-severe PcP at 90 days was lower in the solid-organ transplant recipients than in all other patients (6/26 [23%] versus 34/62 [55%], respectively; P = 0.006), and mortality at 30 days was lower in patients with hematologic malignancies than in all other patients (4/26 [15%] versus 24/62 [39%], respectively; P = 0.03). The outcomes of PcP were not significantly different in moderate-to-severe PcP patients with and without adjunctive corticosteroid use, regardless of recent corticosteroid use. Survival analysis of PcP patients with and without corticosteroid use by the Kaplan-Meier method also did not reveal any difference (log rank test; P = 0.81). There again was no difference within the subgroup of PcP patients with solid-organ transplants. Adjunctive corticosteroid use may not improve the outcome of moderate-to-severe PcP in non-HIV-infected patients.

To assess the effect of add-on corticosteroids on treatment outcomes in lymph node tuberculosis. After registering the protocol on PROSPERO (CRD420251104064), we systematically searched Cochrane, MEDLINE, Embase and Web of Science for randomised controlled trials on adjunct corticosteroids for lymph node tuberculosis up to 20 October 2025. A random-effects model was applied, with heterogeneity quantified using I2 and between-study variance (τ2) estimated by the Paule-Mandel method. Pooled effects were obtained using inverse-variance weighting, and confidence intervals were calculated with the Hartung-Knapp-Sidik-Jonkman (HKSJ) adjustment. Study quality was assessed using RoB 2, and the certainty of evidence was graded using the GRADE framework. Of a total of 485 articles, removing duplicates and irrelevant articles yielded three articles that fulfilled PICOTS criteria. Adjunctive oral prednisone was used as the intervention in all three trials, and treatment outcomes were compared with standard antitubercular treatment. Pooled estimates indicated no significant benefit from the use of adjunctive corticosteroids for complete resolution at 6 months (RR = 1.61; 95% CI: 0.73, 3.56; very low-quality evidence) or symptomatic relief at 2 months (RR = 1.21; 95% CI: 0.92-1.58; low-quality evidence). Adjunctive corticosteroid therapy reduced complications by 77% during the course of treatment in the primary analysis (RR = 0.23; 95% CI: 0.18-0.29). The three studies were at high risk of bias. The certainty of evidence was rated as very low for the outcome of complete resolution at 6 months, low for symptomatic relief at 2 months, and moderate for complications. Though lymph node tuberculosis contributes to a significant portion of all tuberculosis cases, high-quality research related to the use of adjunctive corticosteroids is limited. There is a need for further studies to investigate this promising possibility.

This article summarizes current knowledge on the epidemiology, clinical presentations, diagnosis, and management of selected fungal infections of the central nervous system (CNS). Key syndromes, differential diagnoses, and therapeutic interventions according to host immune status and exposure are reviewed. Advancements in imaging of the brain and spinal cord, and molecular DNA and antigen-based laboratory diagnostics afford improved sensitivity for CNS mycoses. Newer therapeutic strategies may improve outcomes if provided early and host immunosuppression is abrogated. Adjunctive corticosteroid use for disabling neuroinflammation and cerebral edema in the setting of microbiological control may be considered. In addition, nonspecific presentations and absence of fevers in patients without human immunodeficiency virus suggest that screening for Cryptococcus meningitis be performed in all patients with subcortical dementias using a simple CSF or serum antigen test. CNS fungal infections comprise a wide spectrum of clinical syndromes, including abscesses, meningitis/meningoencephalitis, focal masses, stroke/vasculitides, immune reconstitution inflammatory syndrome (IRIS), and spinal pathologies such as arachnoiditis. The main etiologies include Aspergillus, Cryptococcus, Candida, Mucorales, dematiaceous molds, and dimorphic endemic fungi, with the route of acquisition being respiratory or traumatic inoculation with subsequent spread hematogenously or contiguously. Proper management focuses on early effective antifungal therapy and surgery for large or compressive mass lesions. While adjunctive recombinant cytokine or growth factor use has been supported in certain hosts with refractory infections, IRIS-like reactions may occur, suggesting alternative approaches such as high-dose pulse corticosteroids followed by taper.

BackgroundThe current guidelines recommend 21-day adjunctive corticosteroid therapy for HIV-1-infected pneumocystis pneumonia patients (HIV-PCP) with moderate-to-severe disease. Whether shorter adjunctive corticosteroid therapy is feasible in such patients is unknown.MethodsWe conducted a retrospective study to elucidate the proportion of patients with moderate and severe HIV-PCP who required adjunctive corticosteroid therapy for 21 days. The enrollment criteria included HIV-PCP that fulfilled the current criteria for 21-day corticosteroid therapy; PaO2 on room air of <70mmHg or A-aDO2 ≥35 mmHg.ResultsThe median duration of corticosteroid therapy in the 73 study patients was 13 days (IQR 9–21). Adjunctive corticosteroid therapy was effective and discontinued within 10 and 14 days in 30% and 60% of the patients, respectively. Only 9% of the patients with moderate HIV-PCP (n = 22, A-aDO2 35–45 mmHg) received steroids for >14 days, whereas 35% of the patients with severe HIV-PCP (n = 51, A-aDO2 ≥45 mmHg) required corticosteroid therapy for ≥21 days. Four (13%) of the severe cases died, whereas no patient with moderate disease died. Among patients with severe HIV-PCP, discontinuation of corticosteroid therapy within 14 days correlated significantly with higher baseline CD4 (p = 0.049).ConclusionShorter adjunctive corticosteroid therapy was clinically effective and adjunctive corticosteroid could be discontinued within 14 days in 60% of moderate-to-severe HIV-PCP and 90% of moderate cases.

Use of Adjunctive Corticosteroids in Severe Adult Non-HIV Pneumocystis carinii Pneumonia

Cryptococcal meningitis with atypical paradoxical inflammatory reactions after antifungal treatment in acquired immune deficiency syndrome: A case report

To assess whether corticosteroids, used as adjunctive therapy for pediatric severe sepsis, is associated with improved outcomes. Retrospective cohort study examining the clinical database derived from the RESOLVE (REsearching severe Sepsis and Organ dysfunction in children: a gLobal perspective, F1K-MC-EVBP) trial of activated protein C for pediatric severe sepsis. A total of 104 pediatric centers in 18 countries from which data were originally gathered. Children with severe sepsis (n = 477), requiring both vasoactive-inotropic infusions and mechanical ventilation. Within this cohort, 193 children received corticosteroids during their septic episode and 284 did not. None. Baseline summary characteristics demonstrated that children receiving or not receiving corticosteroids had similar demographics and disease severity as indicated by age, gender, mean Pediatric Risk of Mortality scores, and mean number of organ dysfunctions. Use of adjunctive corticosteroids increased during the F1K-MC-EVBP trial. Indications for corticosteroid prescription were therapeutic (89%, mostly shock) and prophylactic (13%). All cause 28-day mortality among children receiving and not receiving corticosteroids was 15.1% and 18.8%, respectively, p = .30. There was no difference in mean vasoactive-inotropic infusion days between the corticosteroid and no corticosteroid groups, 4.5 days vs. 4.3 days, respectively, p = .59. Similarly there was no difference in mean ventilator days between the corticosteroid and no corticosteroid groups, 8.3 days vs. 7.7 days, respectively, p = .38. Children with severe sepsis who received adjunctive corticosteroid therapy exhibited similar illness severity compared with those who did not. No definitive improvement in outcomes can be attributable to adjunctive corticosteroid therapy in the largest pediatric sepsis trial conducted to date.

The use of adjunctive corticosteroids in the treatment of pericardial, pleural and meningeal tuberculosis: Do they improve outcome?

Optimum timing of antiretroviral therapy for HIV-infected patients with concurrent serious opportunistic infections.

Levetiracetam, the S-enantiomer of alpha-ethyl-2-oxo-1-pyrollidine acetamide, is approved for use as adjunctive therapy in adult patients with partial onset seizures. Oral levetiracetam 1000, 2000 and 3000 mg/day administered as adjunctive therapy for up to 18 weeks significantly increased responder rates and reduced seizure frequency compared with placebo in 3 well designed pivotal trials in adults with treatment-refractory partial seizures with or without secondary generalisation. Levetiracetam 3000 mg/day also significantly increased the number of seizure-free patients, but the effects of levetiracetam 1000 and 2000 mg/day on this end-point were unclear. Effects on seizure severity were not assessed in these trials. Although not yet approved as monotherapy or for use in paediatric patients, efficacy was observed with levetiracetam 3000 mg/day as monotherapy in adult patients with refractory partial seizures with or without secondary generalisation and with the 10 to 40 mg/kg/day dosage as adjunctive therapy in children with refractory partial seizures. However, these data are limited. Oral levetiracetam 1000, 2000 and 3000 mg/day as adjunctive therapy is generally well tolerated with an overall incidence of adverse events similar to that observed with placebo. The most commonly reported events in individual clinical trials were CNS-related and included somnolence, asthenia, headache and dizziness. Levetiracetam administered as adjunctive therapy does not appear to interact with other anticonvulsant drugs, and no clinically relevant interactions were observed between levetiracetam and digoxin, warfarin or probenecid; oral contraceptive protective efficacy was also not affected by levetiracetam. Levetiracetam is a new anticonvulsant agent with a favourable tolerability profile and a low potential for drug interactions. It has shown efficacy as adjunctive therapy in patients with treatment-refractory partial onset seizures with or without secondary generalisation in clinical trials. Direct comparative trials with other anticonvulsant agents are not yet available, but placebo-controlled clinical evidence to date suggests that levetiracetam (1000, 2000 and 3000 mg/day) is a useful option as adjunctive therapy in patients with this subtype of epilepsy.

Introduction: Pneumocystis jirovecii (PJ) is an opportunistic fungal pathogen that can cause severe pneumonia in immunocompromised hosts. Risk factors for Pneumocystis jirovecii pneumonia (PJP) include HIV, organ transplant, malignancy, certain inflammatory or rheumatologic conditions, and associated therapies and conditions that result in cell-mediated immune deficiency. Clinical signs of PJP are nonspecific and definitive diagnosis requires direct detection of the organism in lower respiratory secretions or tissue. First-line therapy for prophylaxis and treatment remains trimethoprim-sulfamethoxazole (TMP-SMX), though intolerance or allergy, and rarely treatment failure, may necessitate alternate therapeutics, such as dapsone, pentamidine, atovaquone, clindamycin, primaquine and most recently, echinocandins as adjunctive therapy. In people living with HIV (PLWH), adjunctive corticosteroid use in treatment has shown a mortality benefit. Areas covered: This review article covers the epidemiology, pathophysiology, diagnosis, microbiology, prophylaxis indications, prophylactic therapies, and treatments. Expert opinion: TMP-SMX has been first-line therapy for treating and preventing pneumocystis for decades. However, its adverse effects are not uncommon, particularly during treatment. Second-line therapies may be better tolerated, but often sacrifice efficacy. Echinocandins show some promise for new combination therapies; however, further studies are needed to define optimal antimicrobial therapy for PJP as well as the role of corticosteroids in those without HIV.

The immune reconstitution inflammatory syndrome (IRIS) is a deregulated inflammatory response to invading microorganisms. It is manifested when there is an abrupt change in host immunity from an anti-inflammatory and immunosuppressive state to a pro-inflammatory state as a result of rapid depletion or removal of factors that promote immune suppression or inhibition of inflammation. The aim of this paper is to discuss and re-interpret the possibility of association of paracoccidioidomycosis (PCM) with IRIS in the central nervous system (CNS) in a case from Brazil published by Silva-Vergara ML. et al. (Mycopathologia 177:137-141, 6). An AIDS patient who was not receiving medical care developed pulmonary PCM successfully treated with itraconazole. The patient developed central nervous system PCM (NPCM) after starting the ARV therapy with recovery of immunity and control of HIV viral load, although it was not interpreted as IRIS by the authors, it fulfills the criteria for CNS IRIS. This could be the first case of NPCM associated with IRIS described. Although not frequent, IRIS must be considered in PCM patients and HIV, from endemic areas or patients that traveled to endemic areas, receiving ARV treatment and with worsening symptoms.

IntroductionWe report outcomes from an open-label, non-randomized, 24-week study of eslicarbazepine acetate (ESL) in adults at earlier and later stages of their treatment history for focal seizures, conducted in a real-world clinical setting. MethodsESL was taken as the first adjunctive therapy to levetiracetam (LEV) or lamotrigine (LTG) monotherapy (Arm 1), or as a later adjunctive therapy in treatment-resistant patients (Arm 2). The primary objective was to evaluate the effectiveness of ESL (by retention rates). Secondary objectives were to evaluate efficacy (seizure frequency), safety, tolerability, behavioral changes, mood, and health-related quality of life (HRQoL) associated with ESL treatment. ResultsThe modified intent-to-treat population included 96 patients (Arm 1: n = 41; Arm 2: n = 55) and the safety population included 102 patients (Arm 1: n = 44; Arm 2: n = 58). Overall, 81.8 % of patients in Arm 1 and 63.8 % of patients in Arm 2 completed the 24-week maintenance period. Median reductions in standardized seizure frequency (SSF) were markedly higher in Arm 1 (72.8 %) than Arm 2 (22.8 %), as were responder rates (≥50 % reduction in SSF; Arm 1: 62.5 %; Arm 2: 38.5 %) and rates of seizure freedom (Arm 1: 25.0 %; Arm 2: 9.6 %). Efficacy outcomes were generally more favorable in patients taking ESL in combination with LEV versus other anti-seizure medications (ASMs). Treatment-emergent adverse events (TEAEs; 81 % vs 73 %) and TEAEs leading to discontinuation (16 % vs 2 %) were reported more frequently in Arm 2 than Arm 1, respectively. Serious adverse events were reported infrequently (Arm 1: 0; Arm 2: 7 %). The most common TEAEs were dizziness, nausea, headache, somnolence, fatigue, nasopharyngitis, vomiting, and anxiety. There were no notable changes in depressive symptoms, mood status, or aggression throughout the study. Health and HRQoL scores were generally high at baseline and did not change throughout the study. However, on average, both clinicians and patients perceived improvement in illness over the course of the study. ConclusionsESL was effective and well tolerated both as the first adjunctive therapy to either of the most prescribed first-line ASMs, LEV or LTG, and as a later adjunctive therapy in treatment-resistant patients.

Background: Studies 016 and SETTLE showed that safinamide was safe and effective as adjunct therapy in patients with advanced Parkinson’s disease (PD) and motor fluctuations. The addition of safinamide to a stable dose of levodopa alone or with other antiparkinsonian medications significantly increased ON time with no/non-troublesome dyskinesia, decreased OFF time and improved Parkinson’s symptoms.Objective: To evaluate the clinical effects of safinamide 100 mg/day on motor fluctuations and cardinal Parkinson’s symptoms in specific patient subgroups using pooled data from Studies 016 and SETTLE.Methods: Both studies were double blind, placebo-controlled, randomized, phase 3 trials which enrolled patients with mid- to late-stage PD experiencing motor fluctuations while receiving optimized and stable doses of levodopa, alone or with other dopaminergic treatments. The present post-hoc analyses assessed the change from baseline in ON time (with no or non-troublesome dyskinesia) and OFF time in subgroups of patients who were receiving only levodopa at baseline, who were classified as “mild fluctuators” (daily OFF time ≤4 h), and who were receiving concomitant dopaminergic therapy, with or without amantadine, and the effects of safinamide versus placebo on individual cardinal PD symptoms during ON time.Results: Safinamide significantly increased mean ON time (with no or non-troublesome dyskinesia) and reduced mean OFF time when used as first adjunct therapy in levodopa-treated patients and patients with mild motor fluctuations. Mean daily ON time (with no or non-troublesome dyskinesia) and OFF time were favorably changed, compared with placebo, to similar extents regardless of whether patients were receiving concomitant dopamine agonists, catechol-O-methyltransferase inhibitors and amantadine. Additionally, safinamide improved bradykinesia, rigidity, tremor and gait.Conclusions: Safinamide was a safe and effective first adjunct therapy in levodopa-treated patients and improved 4/5 cardinal symptoms of PD while providing benefits to mild and non-mild fluctuators and patients receiving other concomitant dopaminergic therapies.
