Abstract
A teenage girl presented with fever and altered mental status. MRI showed diffuse leptomeningeal enhancement of the brain and spine. She was diagnosed by a positive cerebrospinal fluid (CSF) culture with tuberculous (TB) meningitis and was started on anti-TB medications and corticosteroids. Her mental status improved, but she was noted to have proximal weakness of the lower extremities. In the course of tapering corticosteroids at week 11 of anti-TB therapy, she became acutely confused and febrile. MRI demonstrated interval development of tuberculomas in the brain and a mass lesion in the thoracic spine causing cord compression. Given the clinical picture was suggestive of a paradoxical reaction, the dose of corticosteroids was increased. Infliximab was added when repeat MRI revealed enlargement of the mass lesion in the spine with worsening cord compression. She was successfully tapered off of corticosteroids. Over several months, the patient's motor function recovered fully, and she returned to ambulating without assistance.

(Re-)introduction of TNF antagonists and JAK inhibitors in patients with previous tuberculosis: a systematic review. Clin Microbiol Infect 2024:S1198-743X(24)00206-4. [PMID: 38663653 DOI: 10.1016/j.cmi.2024.04.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Revised: 04/14/2024] [Accepted: 04/17/2024] [Indexed: 05/20/2024]
Abstract
BACKGROUND Tuberculosis (TB) is a common complication associated with treatment with tumour necrosis factor (TNF) antagonists and Janus kinase (JAK) inhibitors. However, there is uncertainty about the risk of TB relapse in patients with TB and comorbidities requiring treatment with these agents. OBJECTIVES To assess the risk of TB relapse in patients (re-)started on TNF antagonists or JAK inhibitors. METHODS Systematic review. DATA SOURCES PubMed and Cochrane Library databases until 11 December 2023. STUDY ELIGIBILITY CRITERIA Randomized control trials, prospective and retrospective cohort studies, case reports and case series. PARTICIPANTS Patients with current or previous TB who were (re-)started on TNF antagonists or JAK inhibitors. INTERVENTIONS (Re-)introduction of TNF antagonists and JAK inhibitors. ASSESSMENT OF RISK OF BIAS All studies meeting entry criteria were included regardless of quality. METHODS OF DATA SYNTHESIS Categorical data are presented as frequencies and percentages. For non-normally distributed aggregated data, we calculated the pooled weighted median with 95% CI. For individual patient data, the median and interquartile range (IQR) were calculated. RESULTS Of 5018 articles screened for eligibility, 67 publications reporting on 368 TB patients who (re-)initiated treatment with TNF antagonists for underlying diseases were included. The median age was 42.5 years (95% CI: 40.4-42.5) and the proportion of female patients was 36.6% (n = 74) of patients whose sex was reported. A total of 14 patients (3.8%, 95% CI: 2.1-6.3%) developed TB relapse after a median of 8.5 months (interquartile range, 6.8-14.8 months) following (re-)initiation of anti-TNF treatment. Furthermore, among 251 articles screened for eligibility, 11 reports on TB patients who were (re-)started on JAK inhibitors for underlying diseases were identified. The median age was 62 years (interquartile range, 48.5-68.5 years) and 45.5% (n = 5) were female. Only one patient (9.1%; 95% CI: 0.2-41.3%) had TB reactivation 10 months after starting treatment with ruxolitinib. In addition, 94 patients who were treated with TNF antagonists and two patients temporarily treated with JAK inhibitors for the prevention or treatment of paradoxical reactions were analysed. None of the publications reported microbiological failure or worsening of TB-related symptoms. CONCLUSIONS (Re-)initiation of TNF antagonists and JAK inhibitors may be relatively safe in patients with current or previous TB and the need for further treatment of underlying diseases.

Prolonged paradoxical reaction requiring over 5 years of corticosteroid administration in a patient with severe tuberculous meningitis. J Infect Chemother 2024; 30:357-361.

Abstract
Tuberculous meningitis (TBM) is a rare disease in low-incidence countries like Japan, where general physicians have fewer experience with TBM. Despite its proper treatment and early improvement of the condition, TBM often causes paradoxical reactions (PRs), which can lead to severe complications such as stroke. As PRs in the brain are difficult to detect without regular neuroimaging surveillance and have a later onset than in other organs, delayed treatment can be fatal. We report a case of a 54-year-old, human immunodeficiency virus (HIV)-negative man who presented with TBM and miliary tuberculosis (TB) in an unconscious state. Standard anti-tuberculous therapy with adjunctive systemic high-dose dexamethasone brought rapid clinical and microbiological improvement, which allowed the dexamethasone to be tapered. However, he developed cerebral infarction with left hemiplegia due to a TBM-related PR five months after admission. Therefore, the initial high-dose dexamethasone was again added to the anti-tuberculous drugs, achieving the significant effects on the PR-related lesions. Anti-tuberculous drugs had been administered for 3 years and the dexamethasone was carefully tapered. Nevertheless, enlargement of PR-related lesions in the brain recurred 5 years later. Accordingly, the dose of corticosteroid was again increased, resulting in resolving the lesions. It is important to note that severe TBM may cause prolonged PRs, which require a long-term neuroimaging follow-up and anti-inflammatory drugs for the successful management of the TBM-related PR.

Complicated Surgical Site Infection with Mycobacterium Abscessus After Liposuction and Affections of Corticosteroids in the Treatment Regimen: Three Cases Report and a Systematic Review. Aesthetic Plast Surg 2024; 48:1365-1385. [PMID: 37530819 DOI: 10.1007/s00266-023-03512-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Accepted: 06/30/2023] [Indexed: 08/03/2023]
Abstract
INTRODUCTION Mycobacterium abscessus infection after liposuction/fat grafting is a rare complication that is hard to diagnose and treat. Misdiagnosis could result in treatment failure and prolonged hospital stays. The paradoxical reaction is another complication that rarely occurs in non-HIV patients infected with nontuberculosis mycobacteria. This study reported 3 cases infected with M. abscessus complicated by the paradoxical reaction after liposuction and fat grafting. It highlighted characteristics giving clues of the paradoxical reaction and a successful strategy. Also, a systematic review was conducted to comprehensively provide varied aspects of M. abscessus infection after liposuction and/or fat grafting. METHODS Three cases were retrospectively included reporting data characteristics of patients, cosmetic procedures, and treatment strategy. PubMed, Scopus, Virtual Health Library (VHL), and Global Health Library (GHL) were searched to find and include cases with M. abscessus infection after liposuction and/or fat grafting based on defined selection criteria. Relevant data were extracted and summarized. The risk of bias in included studies was assessed using JBI critical appraisal checklists. RESULTS Twenty-four articles were included in the systematic review. Symptoms often developed approximately 1 month after the cosmetic surgery. Culture, AFB, and PCR were common methods of diagnosis of M. abscessus after liposuction and/or fat grafting. It took about 33 days on average from the presentation to isolate and detect the pathogens. Antibiotics based on susceptibility testing results along with surgical interventions were effective methods of treatment. Our three cases which were complicated by the paradox were addressed by adding methylprednisolone for 2 weeks to the macrolide-based therapy. CONCLUSIONS Awareness of this disease should be widely raised among physicians for early diagnosis and proper treatments. Cultures of specimens and AFB should be repeated many times before excluding the possibility of Mycobacterium spp. A paradoxical reaction should be suspected if the symptoms were worse after the antibiotic therapy based on susceptibility testing results and proper surgical interventions, especially if patients had taken corticosteroids before being admitted.

[Paradoxical tuberculosis reaction]. Rev Med Interne 2024:S0248-8663(24)00028-6.

Abstract
Paradoxical tuberculosis reaction is defined as the aggravation of lesions present at diagnosis or the development of new lesions under anti-tuberculosis treatment, after exclusion of other alternate causes. It affects 5 to 30% of tuberculosis patients, with a variable prevalence depending on the site of infection and the clinical background. The diagnosis of paradoxical reaction is one of elimination, and requires having ruled out therapeutic failure, notably linked to poor compliance and/or to the presence of mycobacterial antibiotic resistance. The severity of paradoxical tuberculosis reaction lies in its neurological impairment. Despite its clinical importance, the mechanisms involved remain poorly understood and its management is not consensual. Corticosteroids are the cornerstone in the medical management. The role of anti-TNF agents, currently proposed in cases of corticodependence or corticoresistance, remains to be properly defined.

Abstract
BACKGROUND Tumor necrosis factor α (TNF) inhibitors are used to treat different inflammatory diseases. Although these biologics have an adequate safety profile, they have been associated with paradoxical reactions. MATERIAL AND METHODS Retrospective review of patients on TNF inhibitor therapy who developed a paradoxical skin reaction and were seen at the dermatology department of Hospital Universitari Parc Taulí in Sabadell, Spain. RESULTS We collected data on 30 patients under treatment with a TNF inhibitor who developed an immune-mediated skin reaction in the form of psoriasis (90%), alopecia (6.7%), or neutrophilic dermatitis (3.3%). The most common drugs involved were adalimumab (56.7%) and infliximab (40%). Psoriasiform reactions mostly manifested as generalized plaques (62.9%) or palmoplantar pustulosis (37%). Thirteen patients (43.3%) continued on the same TNF inhibitor and 12 of them (92.3%) achieved partial or complete resolution of lesions. Five patients were switched to a different TNF inhibitor, but none of them achieved complete resolution. Eight patients were switched to a biologic with a different target, and 5 of them (62.5%) achieved partial or complete resolution. CONCLUSIONS Paradoxical reactions during TNF inhibitor therapy do not always require a change of treatment. In our series, the addition of a topical and/or systemic treatment resolved the skin lesions in more than half of the patients, and switching to a drug with a different target was more effective. A change of strategy should be contemplated in more serious cases.

Abstract
BACKGROUND Patients with tuberculous meningitis may worsen despite being treated adequately with anti-tuberculosis drugs. This worsening may lead to re-hospitalization. The exact frequency and causes of re-hospitalization have not been studied previously. We aimed to study the causes of clinical worsening leading to re-hospitalization and its impact on prognosis. METHODS This was a prospective observational study. Newly diagnosed patients with tuberculous meningitis (N = 150) were enrolled. Baseline clinical evaluation, neuroimaging, and cerebrospinal fluid examination were performed. Anti-tuberculosis drug regimen and corticosteroids were given as per WHO guidelines. Patients were followed for 6 months. Re-hospitalized patients were worked up and clinical evaluation, neuroimaging, and cerebrospinal fluid examination were performed again. Outcome assessment was done at the end of 6 months, and a modified Barthel index of ≤ 12 was considered a poor outcome. RESULTS Twenty-three (15.3%) out of 150 patients needed re-hospitalization. The median time between discharge after the first hospitalization and re-hospitalization was 60 days. The common reasons for re-hospitalization were paradoxical neurological deterioration seen in 19 (82.6%) out of 23 patients, followed by drug toxicities (N = 2) and systemic involvement (N = 2). Paradoxically developed spinal arachnoiditis and opto-chiasmatic arachnoiditis were amongst the predominant reasons for re-hospitalization. At six months, re-hospitalization was an independent predictor of poor outcome (OR = 7.39, 95% CI 2.26-24.19). CONCLUSION Approximately 15% of tuberculous meningitis patients needed re-hospitalization. Paradoxically developed spinal arachnoiditis and opto-chiasmatic arachnoiditis were predominant reasons for re-hospitalization. Re-hospitalization adversely affected the outcome.

Abstract
BACKGROUND We sometimes experience disinhibition during bronchoscopy with sedation. However, the impact of adding pethidine on disinhibition has not yet been investigated. This study aimed to examine the additive impact of pethidine on disinhibition during bronchoscopy with midazolam. METHODS This retrospective study involved consecutive patients who underwent bronchoscopy between November 2019 and December 2020 (sedated with midazolam: Midazolam group) and between December 2020 and December 2021 (sedated with midazolam plus pethidine: Combination group). The severity of disinhibition was defined as follows: moderate, disinhibition that always needed restraints by assistants; and severe, disinhibition that needed antagonization of sedation by flumazenil to continue bronchoscopy. One-to-one propensity score matching was used to match baseline characteristics between both groups. RESULTS After propensity score matching with depression, the type of bronchoscopic procedure, and the dose of midazolam, 142 patients matched in each group. The prevalence of moderate-to-severe disinhibition significantly decreased from 16.2% to 7.8% (P = 0.028) in the Combination group. The Combination group had significantly better scores for sensation after bronchoscopy and feelings toward bronchoscopy duration than did the Midazolam group. Although the minimum SpO2 during bronchoscopy was significantly lower (88.0 ± 6.2 mmHg vs. 86.7 ± 5.0 mmHg, P = 0.047) and the percentage of oxygen supplementation significantly increased (71.1% vs. 86.6%, P = 0.001) in the Combination group, no fatal complications were observed. CONCLUSIONS Adding pethidine could reduce disinhibition occurrence in patients undergoing bronchoscopy with midazolam, with better subjective patient outcomes during and after bronchoscopy. However, whether more patients may need oxygen supplementation and whether hypoxia occurs during bronchoscopy should be considered. CLINICAL TRIAL REGISTRATION UMIN000042635.

The use of TNF-α antagonists in tuberculosis to control severe paradoxical reaction or immune reconstitution inflammatory syndrome: a case series and literature review. Eur J Clin Microbiol Infect Dis 2023; 42:413-422.

Abstract
Paradoxical reaction (PR) and immune reconstitution inflammatory syndrome (IRIS) are common complications of tuberculosis treatment. Corticosteroids are first-line treatment for severe PR or IRIS, particularly neurological. We report four cases of severe PR or IRIS during tuberculosis treatment who required TNF-α antagonists, and identified 20 additional cases through literature review. They were 14 women and 10 men, with a median age of 36 years (interquartile range, 28-52). Twelve were immunocompromised before tuberculosis: untreated HIV infection (n=6), or immunosuppressive treatment (TNF-α antagonists, n=5; tacrolimus, n=1). Tuberculosis was mostly neuromeningeal (n=15), pulmonary (n=10), lymph node (n=6), and miliary (n=6), multi-susceptible in 23 cases. PR or IRIS started after a median time of 6 weeks (IQR, 4-9) following anti-tuberculosis treatment start, and consisted primarily of tuberculomas (n=11), cerebral vasculitis (n=8), and lymphadenitis (n=6). First-line treatment of PR or IRIS was high-dose corticosteroids in 23 cases. TNF-α antagonists were used as salvage treatment in all cases, with infliximab (n=17), thalidomide (n=6), and adalimumab (n=3). All patients improved, but 6 had neurological sequelae, and 4 had TNF-α antagonist-related severe adverse events. TNF-α antagonists are safe and effective as salvage or corticosteroid-sparing therapeutic for severe PR or IRIS during tuberculosis treatment.

Abstract
BACKGROUND Intracranial tuberculomas are infrequent with a lower morbidity and mortality compared to tubercular meningitis. Giant intracranial tuberculomas are rarer but important differentials for intracranial space-occupying lesions causing focal neurological deficits depending on anatomical location and size. METHODS Histopathologically confirmed giant intracranial tuberculomas selected based on institutional size criteria (<12 Years-old: ≥25 mm; 12-18 Years-old: ≥35 mm; ≥18 Years-old: ≥40 mm) were retrospectively reviewed and analyzed for clinical features, radiology, surgical management, and outcomes in patients admitted from 2015 to 2022. RESULTS Ten patients were included (Males:Females = 3:7; Age: 8-68 Years, Average: 30.1 Years). Mean duration of symptoms was 2.84 months. Two patients demonstrated active systemic tuberculosis. Previous tubercular infections included pulmonary involvement in four, meningeal in three, and a cerebellar tuberculoma in one patient. Cerebrospinal fluid analysis in five patients demonstrated no tubercle bacilli. Seven lesions were supratentorial and three infratentorial. Giant tuberculomas demonstrated profound T2 hypointensity, sub-marginal T2 hyperintense crescents, and significant perilesional vasogenic edema. Craniotomy and excision were mainstay except in one case treated only with ventriculoperitoneal shunting. Three additional patients underwent ventriculoperitoneal shunting for hydrocephalus. One patient died from aspiration pneumonia and sepsis following a postoperative seizure. Anti-Tubercular Therapy (ATT) was advised for 18 months. Follow up ranged from 4 to 18 months. One patient was medically managed for ATT-induced hepatitis, hepatic encephalopathy, and coincidental paradoxical reaction. Remainder of patients showed complete resolution of symptomatology and absence of new symptoms till latest follow up. CONCLUSION Clinical course of giant tuberculomas differ from non-giant variants in characteristic radiology, more intensive ATT, and possibility for partial debulking/excision.

Abstract
Cutaneous leishmaniasis is an important cause of nonhealing lesions in those recently immigrated to the United States from endemic areas. The lesions can present with various characteristics such as ulcerations, macules, or papules, and may be painful or painless. Several diagnostic modalities, including polymerase chain reaction testing, should be performed to identify the causative Leishmania species which is important in determining appropriate treatment. We describe a case of cutaneous leishmaniasis caused by Leishmania panamensis in a patient who recently traveled through South and Central America.

Abstract
BACKGROUND Extrapulmonary tuberculosis commonly affects the lymphatic system, nervous system, and gastrointestinal system. Tuberculous infection in the muscle is very rare. Moreover, tuberculous infection in the diaphragm is extremely rare. We herein report a case of tuberculomas in the diaphragm and posterior mediastinum that were successfully diagnosed and treated. CASE PRESENTATION We encountered a 62-year-old woman with a tuberculoma in the diaphragm. The patient presented with mild dyspnea. Computed tomography showed a mass in the left diaphragm, focal thickening of the posterior mediastinum, and multiple nodules in the lungs. Positron emission tomography-computed tomography showed increased uptake in the left diaphragm mass and thickening of the posterior mediastinum; therefore, we considered the masses to be malignant and planned surgical resection. However, the patient was diagnosed with tuberculosis from a sputum culture, and she was treated with anti-tuberculous therapy. The masses in the diaphragm and posterior mediastinum had become enlarged after 6 months of anti-tuberculous therapy; therefore, the patient underwent resection of both masses. Tuberculous infection was histologically confirmed in each lesion. She was pathologically diagnosed with tuberculous abscesses in the diaphragm and posterior mediastinum and began treatment with anti-tuberculosis drugs. CONCLUSIONS Preoperative diagnosis of a tuberculoma in the diaphragm is usually difficult, and surgical intervention is important for both diagnosis and treatment.

RESULTS Among 251 eligible patients who were sedated using midazolam, 36 (14.3%; 95% confidence interval [CI], 10.5%-19.2%), 42 (16.7%; 95% CI, 12.6%-21.8%), and 7 (2.8%; 95% CI, 1.4%-5.6%) experienced mild, moderate, and severe disinhibition, respectively. Depression (odds ratio [OR] 2.77; 95% CI, 1.20-6.41), endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) (OR 10.23; 95% CI, 1.02-103.01, referred to brushing/bronchial washing/observation), and increased administration of midazolam (OR 1.20; 95% CI, 1.02-1.42, per 1-mg increase) were independently associated with moderate-to-severe disinhibition. Patients experiencing moderate disinhibition reported significantly better scores for discomfort during bronchoscopy. Besides the maximum systolic and diastolic blood pressures during bronchoscopy, the changes in hemodynamic and respiratory statuses during bronchoscopy or complications did not significantly differ between patients experiencing moderate-to-severe disinhibition and those experiencing none-to-mild disinhibition. CONCLUSIONS Moderate-to-severe disinhibition occurred in 19.5% of patients during bronchoscopy with midazolam. We should focus on disinhibition when patients have depression or are planning to undergo EBUS-TBNA, and sparing the administration of midazolam might reduce the occurrence of disinhibition.

Propofol Alone versus Propofol in Combination with Midazolam for Sedative Endoscopy in Patients with Paradoxical Reactions to Midazolam. Clin Endosc 2021; 55:234-239. [PMID: 34634857 PMCID: PMC8995981 DOI: 10.5946/ce.2021.126] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Accepted: 05/19/2021] [Indexed: 11/14/2022] Open
Abstract
Background/Aims The efficacy of propofol in gastrointestinal endoscopy for patients with midazolam-induced paradoxical reactions remains unclarified. This study aimed to compare the efficacy and safety of propofol-based sedation in patients who previously experienced paradoxical reactions. Methods This was a prospective, single-blinded, randomized controlled pilot study. Participants with a history of paradoxical reactions to midazolam during a previous esophagogastroduodenoscopy were recruited and randomly assigned to group I (propofol monosedation) or group II (combination of propofol and midazolam). The primary endpoint was the occurrence of a paradoxical reaction. Results A total of 30 participants (mean age, 54.7±12.6 years; male, 19/30) were randomly assigned to group I (n=16) or group II (n=14). There were no paradoxical reactions in group I, but there were two in group II, without a significant difference (p=0.209). The mean dose of propofol was higher in group I than in group II (p=0.002). Meanwhile, the procedure and recovery times did not differ between groups. Conclusions Propofol-based sedation was safe and effective for patients who experienced paradoxical reactions to midazolam. However, caution is needed because few cases of paradoxical reaction again can happen in group II in which midazolam was readministered.

Abstract
Background Previous studies have reported that presence and severity of Buruli ulcer (BU) may reflect the underlying immunosuppression in HIV infected individuals by causing increased incidence of multiple, larger and ulcerated lesions. We report cases of BU-HIV coinfection and the accompanying programmatic challenges encountered in central Ghana. Methods Patients with PCR confirmed BU in central Ghana who were HIV positive were identified and their BU01 forms were retrieved and reviewed in further detail. A combined 16S rRNA reverse transcriptase / IS2404 qPCR assay was used to assess the Mycobacterium ulcerans load. The characteristics of coinfected patients (BU+HIV+) were compared with a group of matched controls. Results The prevalence of HIV in this BU cohort was 2.4% (compared to national HIV prevalence of 1.7%). Eight of 9 BU+HIV+ patients had a single lesion and ulcers were the most common lesion type. The lesions presented were predominantly category II (5/9) followed by category I lesions. The median (IQR) time to healing was 14 (8–28) weeks in the BU+HIV+ compared to 28 (12–33) weeks in the control BU+HIV− group (p = 0.360). Only one BU+HIV+ developed a paradoxical reaction at week 16 but the lesion healed completely at week 20. The median bacterial load (16SrRNA) of BU+HIV+ patients was 750 copies /ml (95% CI 0–398,000) versus 500 copies/ml (95% CI 0–126,855,500) in BU+HIV− group. Similarly, the median count using the IS2404 assay was 500 copies/ml (95% CI 0–500) for BU+HIV+ patients versus 500 copies/ml (95% CI 500–31,000) for BU+HIV− patients. BU+HIV− patients mounted a significantly higher interferon-γ response compared to the BU+HIV+ co-infected patients with respective median (range) responses of [1687(81.11–4399) pg/ml] versus [137.5(4.436–1406) pg/ml, p = 0.03]. There were challenges with the integration of HIV and BU care in this cohort. Conclusion The prevalence of HIV in the BU+ infected population was not significantly increased when compared to the prevalence of HIV in the general population. There was no clear relationship between BU lesion severity and HIV viral load or CD4 counts. Efforts should be made to encourage the integration of care of patients with BU-HIV coinfection.

Mitral valve granulomatosis: A paradoxical reaction complicating etanercept treatment in rheumatoid arthritis. A case report. Joint Bone Spine 2021; 88:105183. [PMID: 33838309 DOI: 10.1016/j.jbspin.2021.105183] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2021] [Accepted: 03/26/2021] [Indexed: 11/20/2022]
Abstract
BACKGROUND "Sarcoidosis-like" paradoxical reactions to Antitumor necrosis factor α (anti-TNFα) treatment have been reported. The clinical presentations are varied, most of the time, with a relatively typical picture of mediastinopulmonary involvement. More rarely, isolated granulomatous locations from various organs are described, leading to difficulties in diagnosis. CASE PRESENTATION We report a granulomatous cardiac valve location complicating etanercept treatment in a 26-years-old caucasian male with rheumatoid arthritis. The patient received leflunomide and low-dose corticosteroids, then etanercept was introduced because of persistent disease activity. He had no history of tuberculosis infection or contact, chest CT-scan was normal. At 3 months, he showed complete remission. After 6 months of etanercept treatment, the patient suddenly complained of headache with scotomas of the right visual field and vertigo, without fever. Cerebral MRI revealed 3 recent infarcts. Cardiac ultrasonography revealed a mobile mass on the posterior mitral leaflet. C-reactive protein level was 8mg/L, and all analyses were negative for an infectious agent. Leflunomide and etanercept were discontinued, and antibiotic therapy was started. Mitral valve resection and plasty were performed 2 days later. Histology of the valve revealed large non-caseating epithelioid granulomas with a suppurative-like necrotic center. After ruling out infectious endocarditis, sarcoidosis, rheumatoid valvulitis or lupus-like reaction induced by anti-TNF therapy, the diagnosis of a paradoxical reaction to etanercept was finally retained. Tocilizumab monotherapy was introduced to treat RA flare, no antibiotic preventive treatment was added. After 2 years, the patient was in remission. CONCLUSION This case raises for the first time the possibility of a paradoxical adverse event with an isolated granulomatous reaction on the heart valve occurring with anti-TNF treatment, namely etanercept.

Abstract
Tuberculous (TB) meningitis (TBM), accounting for 70-80% of cases of neurotuberculosis, is one of the most severe forms of extrapulmonary tuberculosis. Two-thirds of new TB cases come from eight countries. Polymorphisms in toll-interleukin-1 receptor domain and in leukotriene A4 hydrolase (LTA4H) gene, affect the risk of inflammation in TBM. The common site of tuberculoma in children is cerebellum, and they may rarely develop tuberculous encephalopathy which has a high mortality. Young females with a high cerebrospinal fluid (CSF) protein have an increased predisposition to develop optochiasmatic arachnoiditis. Spinal TB meningitis may mimic transverse myelitis or Guillain-Barre syndrome. An extra-neural focus of TB should be sought clinically and radiologically as it may indicate safer and more accessible sites for diagnostic samplings. Cartridge-based nucleic acid amplification test (CBNAAT), also known as Genexpert test, is a polymerase chain reaction (PCR)-based method for detection of TB which also detects rifampicin resistance as it targets the rpob gene of mycobacteria. Line probe assays, based on PCR and reverse hybridization methods, identify mutations associated with drug resistance within a week. TBM being a paucibacillary disease, often evades a definite diagnosis and empirical treatment for a minimum of 9 months is warranted based on clinical judgement. All TBM patients should receive adjunctive corticosteroids, even those with HIV infection. Drug resistance is strongly associated with previous treatment and bedaquiline as well as delamanid have received approvals for multidrug resistant (MDR) TB. The key principle of managing MDR TB is never to add a single drug to a failing regimen. Correct combination and duration of most effective second line drugs in MDR TB require further modifications. Early shunting should be considered in those with hydrocephalus failing medical management. The single most important determinant of outcome is the stage of TBM at which treatment has been started.

Abstract
This study aimed at providing valid estimates for the risk of clinically relevant seizure aggravation by recommended anti-seizure medications in patients with Genetic Generalized Epilepsy (GGE). To this aim, treatment response, side effects and paradoxical reactions to anti-seizure treatment were retrospectively assessed in a near-population based cohort comprising 471 adult GGE patients. A total of 1046 treatment attempts were analyzed (lamotrigine: 351, valproic acid: 295, levetiracetam: 249, primidone/phenobarbital: 94, zonisamide: 57). Under lamotrigine, seizure aggravation was observed in 15 patients (two patients during levetiracetam, one patient during zonisamide, none during phenobarbital and valproic acid). All but two patients with paradoxical reactions to lamotrigine were diagnosed with juvenile myoclonic epilepsy (JME), otherwise, the clinical and electroencephalographic characteristics of patients with paradoxical reactions did not differ. At treatment start, the estimated risk of a paradoxical reaction to lamotrigine was 7.9 % in JME patients (n = 190). For all GGE patients (incl. JME), the estimated risk of clinically relevant seizure aggravation under treatment with lamotrigine was 3.7 % (1.8 % for zonisamide and 0.8 % for levetiracetam). In conclusion, clinical significant aggravation of seizure frequency is common in lamotrigine-treated JME patients but rare in patients with other GGE subsyndromes or under treatment with other recommended anti-seizure medication.

Abstract
A 31-year-old female presented with a 3-week history of fever and headache. CSF Ziehl-Neelsen smear microscopy revealed acid-fast bacilli, and CSF GeneXpert MTB/RIF was positive for Mycobacterium tuberculosis with no mutations of rifampicin resistance. Tuberculous meningitis (TBM) was diagnosed. Baseline contrast-enhanced brain magnetic resonance imaging (MRI) was unremarkable. Eight weeks later the patient developed markedly reduced visual acuity and clinical signs consistent with left 3rd and 6th cranial nerve palsies. Repeat contrast-enhanced brain MRI revealed extensive tuberculous exudate filling the basal cisterns of the brain consistent with a severe paradoxical reaction of TBM. High dose intravenous dexamethasone was administered, with visual acuity returning to near-normal over 3-4 weeks. In TBM paradoxical inflammatory reactions are common yet difficult to predict. When severe, they may result in substantial neurological morbidity and death. Prompt host directed therapies such as corticosteroids may reduce chances of permanent neurological damage.

Plasma interferon-γ-inducible protein 10 (IP-10) levels correlate with disease severity and paradoxical reactions in extrapulmonary tuberculosis. Infection 2020; 49:437-445.

Abstract
BACKGROUND With 1.5 million deaths worldwide in 2018, tuberculosis (TB) remains a major global public health problem. While pulmonary TB (PTB) is the most common manifestation, the proportion of extrapulmonary TB (EPTB) is increasing in low-burden countries. EPTB is a heterogeneous disease entity posing diagnostic and management challenges due to the lack of reliable biomarkers. In this study, we prospectively evaluated clinical data and treatment response which were correlated with different biomarkers. METHODS The study was conducted at the University Hospital of Cologne. 20 patients with EPTB were enrolled. We analyzed plasma interferon-γ-inducible protein 10 (IP-10) levels in plasma by ELISA for up to 12 months of treatment. In addition, the QuantiFERON®-TB Gold Plus (QFT® Plus) test was performed during the course of treatment. Clinical data were assessed prospectively and correlated with QFT® Plus and IP-10 levels. RESULTS Plasma IP-10 levels were found to be significantly increased (p < 0.001) in patients with extensive disease compared to patients with limited disease (cervical lymph node TB) or healthy controls. In patients with clinically confirmed paradoxical reaction (PR), a further increase of IP-10 was noted. IFN-γ measured by the QFT® Plus test did not decrease significantly during the course of treatment. Of note, in four EPTB patients (20%) without radiographic pulmonary involvement, sputum culture was positive for Mycobacterium tuberculosis. CONCLUSION Our data demonstrate that IP-10 may be a valuable biomarker for estimation of disease severity in EPTB and monitoring of the disease course in extensive forms. However, IP-10 may be less suitable for diagnosis and monitoring of EPTB patients with limited disease. The QFT® Plus test does not appear to be a suitable marker for therapy monitoring. Sputum should be examined in EPTB patients even in case of normal diagnostic imaging of the chest.

Abstract
BACKGROUND Tuberculous lymphadenitis is the most common form of extrapulmonary tuberculosis. This study was primarily designed to assess clinical characteristics of Peripheral tubercular lymphadenitis and incidence of Paradoxical reaction. MATERIALS & METHODS It is a prospective observational study for 130 peripheral Lymph node tuberculosis patients diagnosed and treated between 1st Jan 2018 to 31st Dec 2019. All statistical analyses were performed using statistical software SPSS version 20 (SPSS Inc, Chicago, USA). A P value of <0.05 is considered significant. RESULTS Out of 130 study patients, 54 were male, and 76 were female, with a sex ratio of 1:1.4. The mean age of the patients was 28.01 years (±12.41). Almost one-fourth of study patients (25.38%) had symptoms for more than one years before the diagnosis of tubercular lymphadenitis. Of the 130 patients, 62 (47.69%) were classified as having confirmed TB based on AFB positivity in FNAC sample. More than half of study patients (55.38%) received homoeopathic treatment before initiation of anti-tubercular treatment. The most common Lymph node involved was cervical (66.15%). Forty-six (35.38%) patients developed Paradoxical reaction, and most of this occurred in the first two months of the initiation of Anti-tubercular treatment. Fifty-eight patients (44.61%) had a residual Lymph node of size more than one centimetre after six months of treatment. Only 9 patients out of 54 patients had significant reduction in the size of the lymph node with 9 months of treatment. CONCLUSION Significant number of patients had residual lymph node at the end of 6 months of treatment, but extending the treatment to 9 months was not beneficial. More than half of patients had history of homoeopathic treatment that could lead to delayed presentation. The paradoxical reaction is very common but most of it subsided spontaneously.

Abstract
Paradoxical reactions to tuberculosis (TB) treatment are characterized by an initial improvement of the clinical symptoms followed by clinical or radiological deterioration of existing tuberculous lesions, or by development of new lesions. Intestinal perforation in gastrointestinal TB can occur as a paradoxical reaction to antitubercular therapy. A 55-year-old man visited the outpatient department with lower abdominal pain and weight loss. He was diagnosed with intestinal TB and started antitubercular therapy. After 3 months of antitubercular therapy, a colonoscopy revealed improvement of the disease. Three days after the colonoscopy, the patient visited the emergency room complaining of abdominal pain. Abdominal computed tomography revealed extraluminal air-filled spaces in the pelvic cavity. We diagnosed a small bowel perforation and performed an emergency laparotomy and a right hemicolectomy with small bowel resection. This report describes the case of intestinal perforation presenting as a paradoxical reaction to antitubercular and provides a brief literature review.

Characteristics of paradoxical tuberculosis-associated immune reconstitution inflammatory syndrome and its influence on tuberculosis treatment outcomes in persons living with HIV. Int J Infect Dis 2020; 98:261-267.

Abstract
OBJECTIVE The influence of tuberculosis (TB)-immune reconstitution inflammatory syndrome (IRIS) on TB treatment outcomes and its risk factors were investigated among people with human immunodeficiency virus (HIV) and co-infected with TB. METHODS Newly diagnosed, culture-confirmed, pulmonary TB patients with HIV and enrolled in a clinical trial (NCT00933790) were retrospectively analysed for IRIS occurrence. Risk factors and TB outcomes (up to 18 months after initiation of anti-TB treatment [ATT]) were compared between people who experienced IRIS (IRIS group) and those who did not (non-IRIS group). RESULTS TB-IRIS occurred in 82 of 292 (28%) participants. Significant baseline risk factors predisposing to TB-IRIS occurrence in univariate analysis were: lower CD4+ T-cell count, CD4/CD8 ratio, haemoglobin levels, presence of extra-pulmonary TB focus, and higher HIV viral load; the last two retained significance in the multivariate analysis. After 2 months of ATT commencement, sputum smear conversion was documented in 45 of 80 (56.2%) vs. 124 of 194 (63.9%) (p=0.23), culture conversion was in 75 of 80 (93.7%) vs. 178 of 194 (91.7%) (p=0.57) and the median decline in viral load (log10copies/mm3) was 2.7 in the IRIS vs. 1.1 in the non-IRIS groups (p<0.0001), respectively. An unfavourable response to TB therapy was detected in 17 of 82 (20.7%) and 28 of 210 (13.3%) in the IRIS and non-IRIS groups, respectively (p=0.14). CONCLUSIONS TB-IRIS frequently occurred in people with advanced HIV infection and in those who presented with extra-pulmonary TB lesions, without influencing subsequent TB treatment outcomes.

Abstract
Introduction Biologic agents form an indispensable part of modern therapeutic regimens for the treatment of severe inflammatory diseases, especially in the fields of rheumatology, dermatology and gastroenterology. They are favoured by both physicians and patients due to their high effectiveness, good patient tolerance and safety. However, interference in the regulation and dynamics of inflammatory cytokines can on occasion lead to an onset of a dermatological condition also known as paradoxical skin reaction. Here, we present a case of paradoxical skin reaction induced by certolizumab. Case Report A young woman with ankylosing spondylitis developed a severe and complex cutaneous reaction after 6 months of otherwise successful treatment with certolizumab. The diagnosis of a rare paradoxical cutaneous reaction post anti-tumour necrosis factor alpha treatment was based on overlapping features of pyoderma gangrenosum and palmoplantar pustular psoriasis. Alopecia developed and there was also nail involvement. Treatment proved to be challenging as the disease did not remit after the patient ceased treatment with certolizumab. The patient was started on a combination of secukinumab and methotrexate to control the symptoms, with a promising outcome. Conclusion Paradoxical skin reactions are an emerging clinical entity that require further research in order to establish risk factors and best personalized treatment.

Abstract
Background Paradoxical reaction after the initiation of tuberculosis treatment is defined as increased inflammation following effective antimycobacterial treatment. This is a phenomenon that can severely complicate a patient’s recovery, potentially leading to further morbidity and residual deficits. Paradoxical reaction remains poorly understood regarding its pathophysiology and management. Only a limited number of reports look critically at the available therapeutic options, with evidence of the efficacy of prednisolone therapy being primarily limited to extrapulmonary PR only. Case We describe two HIV negative patients who were admitted to our department with pulmonary tuberculosis, presenting with inflammatory patterns attributable to PR and their response to adjunctive steroid therapy. Discussion and Conclusions The presented cases further highlight the need for immunological studies and randomized trials for corticosteroid therapy are needed to better understand this phenomenon as well as provide an evidence-base for anti-inflammatory treatment. Furthermore, by means of this case series, we are also able to highlight the potential variability in the symptomatology of the lesser known PR phenomenon, in which we observed a hypotensive shock-like syndrome not previously described in literature.

Abstract
A paradoxical reaction (PR) is an excessive immune response occurring during antitubercular therapy (ATT), but is rare in patients with miliary tuberculosis. A 78-year-old woman complained of general malaise, loss of appetite, and fever for 10 days. Chest computed tomography (CT) showed diffuse, bilateral, discrete miliary nodules. The patient was treated with ATT for miliary tuberculosis. Nine days after starting the treatment, she developed a spiking fever and worsening malaise. Repeat CT showed new localized ground-glass opacity (GGO) in the right upper lobe. After excluding possible etiologies, she was diagnosed with PR due to ATT. She was successfully managed with oral prednisolone while continuing ATT. The GGO diminished and did not recur after discontinuation of the steroids. We reviewed 28 reported cases of miliary tuberculosis with a PR in patients not infected with human immunodeficiency virus. Those not on immunosuppressive therapy were likely to develop a PR early. This case illustrates that a PR may present as localized GGO in miliary tuberculosis in the lung of patients treated with ATT. In cases of a PR with marked symptoms, steroid therapy may be valuable.

Abstract
Tuberculosis associated Immune reconstitution inflammatory syndrome (IRIS) in a HIV negative patient can present with a multitude of clinic-radiological presentations that are often confused with drug resistance/treatment failure. Being a diagnosis of exclusion, this clinical entity is often prone to under-diagnosis. We present a series of 5 patients who presented with varied but uncommon IRIS manifestations. High index of suspicion coupled with clinical reasoning and judicious use of phenotypic and genotypic culture methods helped in their timely detection and successful treatment.

A surgical case of cerebellar tuberculoma caused by a paradoxical reaction while on therapy for tuberculosis spondylitis. Surg Neurol Int 2019; 10:162. [PMID: 31528497 PMCID: PMC6744749 DOI: 10.25259/sni_318_2019] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2019] [Accepted: 07/04/2019] [Indexed: 12/15/2022] Open
Abstract
Background: A paradoxical reaction (PR) is a phenomenon in which the primary tuberculous lesion worsens or another de novo tuberculous lesion appears while on anti-tuberculosis therapy. Here, we report a rare case of cerebellar tuberculoma caused by a PR during therapy for lumbar tuberculous spondylitis (Pott’s disease). Case Description: A 47-year-old male with human immunodeficiency virus seronegative was diagnosed with lumber tuberculous spondylitis (Pott’s disease) and prescribed anti-tuberculous agents. His lower back pain and inflammatory condition recovered after initiation of anti-tuberculous therapy. Two months later, he complained of headache, nausea, and staggering. Magnetic resonance images revealed a ring-enhanced lesion located at the cerebellar hemisphere extending to the vermis, which caused perifocal edema and bilateral ventriculomegaly. These findings were consistent with his symptoms of hydrocephalus. He did not have preceding clinical findings of meningitis, and a PR was suggested to cause de novo aggregation of cerebellar tuberculoma. A lesionectomy was performed, and the surgical specimen was pathologically diagnosed as a tuberculoma. He recovered well from neurological disorders after the resection. Conclusion: De novo formation of intracranial tuberculoma alone caused by a PR without preceding meningitis is very rare. Lesionectomy is needed for intracranial tuberculoma, which manifests as a mass effect, as well as antituberculous therapy.

Abstract
Paradoxical reactions following initiation of anti-tubercular therapy have been documented most often in extrapulmonary tuberculosis. A combination of factors such as delayed hypersensitivity, decreased suppressor mechanisms, and an increased response to mycobacterial antigens mediated by the host’s immune system have been implicated in the development of these reactions. Similar worsening in patients with ocular tuberculosis while on treatment has been described. It is therefore important for the clinician to be aware of this occurrence, as prompt recognition and timely institution of corticosteroids and immunosuppressants can lead to restoration of vision. In these patients, an alteration or discontinuation of anti-tubercular therapy may not be indicated.

Abstract
BACKGROUND Tuberculous meningitis (TBM) accounts for 1-4% of all tuberculosis (TB) presentations. Paradoxical deterioration in non-HIV patients is a common manifestation of anti-tuberculosis therapy, characterised by clinico-radiological deterioration. We report a case series of TBM admissions to our institution including one case with paradoxical deterioration refractory to corticosteroids who responded to adjuvant cyclosporine. METHODS Retrospective review of 12 HIV-negative patients admitted to Liverpool Hospital, Sydney (2005-2016) with laboratory and/or radiologically confirmed TBM. RESULTS Median patient age was 40 (range 22-81 years), M:F = 7:5. Eleven patients (92%) were of Asia-Pacific origin. Eleven initially presented with central nervous system manifestations and one had preceding miliary TB. Nine patients had extra-cranial TB involvement including eight with past or current pulmonary disease. Cerebrospinal fluid (CSF) TB PCR/culture was positive in 10 patients. Paradoxical deterioration developed in three patients despite concomitant corticosteroids in two. One patient with paradoxical deterioration was refractory to corticosteroids: A 22-year-old Vietnamese male with TBM developed worsening headaches and altered mentation after seven weeks concomitant anti-TB and corticosteroid treatment. Interval MRI brain demonstrated increased size and number of tuberculomas as well as hydrocephalus. Cyclosporine was added with gradual improvement and ultimately good outcome. CONCLUSION Our case series highlights the seriousness of paradoxical deterioration in TBM and the potential role of adjuvant cyclosporine in patients refractory to corticosteroids.

Abstract
Inflammatory bowel disease (IBD) is associated with a number of extraintestinal complications, including skin lesions. Most reports have shown that skin lesions are found in 10-15% of IBD cases, although this depends on the definition of skin lesions. The representative skin lesions in patients with IBD are erythema nodosum, pyoderma gangrenosum, Sweet's syndrome, and so on. These lesions are often associated with IBD progression, and intestinal lesions in particular require appropriate treatment. Recently, another clinical issue regarding skin lesions in patients with IBD, a so-called paradoxical reaction, during the treatment with anti-tumor necrosis factor (TNF)-α agents has emerged. These reactions are termed paradoxical reactions because the skin lesions sometimes resemble psoriasis, although the anti-TNF-α agents have been historically used to treat psoriasis. Paradoxical reactions are reportedly found in approximately 5-10% of patients using anti-TNF-α agents and are no longer rare. Now that the use of biologics is at its culmination, reports regarding paradoxical reactions are predicted to increase in number; thus, we must recognize skin lesions with IBD patients including this type of adverse events and manage them appropriately while consulting with dermatologists.

Abstract
OBJECTIVE The aim of this study was to investigate the occurrence of paradoxical reaction (PR) in HIV-negative tuberculous meningitis (TBM) patients with spinal involvement, as well as its possible risk factors. METHODS Fifty TBM patients with spinal involvement were studied retrospectively and divided into a PR group and a non-PR group according to the presence of PR. Their demographic, clinical, radiological, and laboratory data, and status at follow-up were collected and compared. RESULTS PR developed in 26 patients (52%), with the median time to the development of PR being 30days (range 15-330 days) after the initiation of tuberculosis therapy. At initial diagnosis, age, documented acid-fast bacilli (AFB), and the cerebrospinal fluid protein level were found to differ significantly between the two groups. After multivariate analysis, age, documented AFB, and vertebral involvement were significantly associated with the development of PR. CONCLUSIONS PR was common in TBM patients with spinal involvement. Age, documented AFB, and musculoskeletal involvement may be predictors of PR development.

Abstract
A 75-year-old woman with a history of immunosuppressive treatment for rheumatoid arthritis and non-Hodgkin lymphoma, was referred to our reference centre for treatment of tenosynovitis caused by Mycobacterium malmoense, which had disseminated due to immunosuppressive therapy. This rare diagnosis was made after years of treatment for supposed rheumatoid arthritis. The patient presented with relapsing tenosynovitis with wounds on her right middle finger and wounds on her left lower leg, despite 3 months of adequate therapy (rifampicin+ethambutol+clarithromycin). Therapy was intensified with amikacin, clofazimine, moxifloxacin, and interferon-gamma due to the lack of response. Amputation of the right middle finger was necessary due to advanced disease. Treatment was further complicated by a paradoxical reaction, requiring prednisone treatment, which ultimately led to cure.

Abstract
Biologic drugs, which are molecules designed to act on specific immune system targets, have been shown to be very effective in treating various dermatological, rheumatological, and systemic diseases. As a group, they have an acceptable safety profile, but their use has been associated with the onset of both systemic and organ-specific inflammatory conditions. True paradoxical reactions are immune-mediated disorders that would usually respond to the biologic agent that causes them. There is still debate about whether certain other adverse reactions can be said to be paradoxical. The hypotheses proposed to explain the pathogenesis of such reactions include an imbalance in cytokine production, with an overproduction of IFN-α and altered lymphocyte recruitment and migration (mediated in part by CXCR3), and the production of autoantibodies. Some biologic therapies favor granulomatous reactions. While most of the paradoxical reactions reported have been associated with the use of TNF-α inhibitors, cases associated with more recently introduced biologic therapies -such as ustekinumab, secukinumab, and ixekizumab- are increasingly common. The study of paradoxical adverse events not only favors better management of these reactions in patients receiving biologic therapy, but also improves our knowledge of the pathogenesis of chronic inflammatory diseases and helps to identify potential therapeutic targets.

Abstract
A 26-year-old HIV-negative male from Ghana was treated for cervical, intrathoracic and abdominal lymph node tuberculosis (TB) and tuberculous hepatitis. Penetration of the thoracic trachea by a mediastinal lymph node had caused bronchomucosal TB. Sputum culture grew M. africanum, sensitive to all first-line antituberculous drugs. Four weeks after the beginning of directly observed treatment with isoniazid, rifampin, pyrazinamide and ethambutol, the right cervical lymph node increased in size, liquefied and caused a spontaneous fistula. A biopsy of the necrotized lymph node revealed rare acid-fast bacilli with a positive PCR for Mycobacterium tuberculosis complex. After debridement, vacuum-assisted closure therapy was performed for 6 weeks. Five months after the beginning of antituberculous therapy, a second paradoxical reaction occurred, with painful swelling of two contralateral supraclavicular lymph nodes. Extirpation of one node yielded a positive PCR for M. tuberculosis complex; the culture was negative. Antituberculous treatment was continued, and additional treatment with oral prednisolone 20 mg daily for 1 month tapering over 10 weeks was introduced, resulting in a decrease in lymphadenopathy. Antituberculous treatment was continued for a total of 9 months. The outcome was favorable, no further lymphadenopathy occurred over the following 6 months.

Abstract
Miliary tuberculosis is a severe form of tuberculosis resulting from dissemination of Mycobacterium tuberculosis bacilli. Since symptoms appearing in patients due to miliary TB are diverse and atypical, depending on the site of invasion, early diagnosis and treatment are important. A paradoxical response of tuberculosis is a rare phenomenon and it can be a clinical difficulty to treatment especially when involving the central nervous system. We present a case report with a review of related literature about the patient who developed sudden hearing loss due to tuberculosis infection in vestibulocochlear area.

Abstract
Anti-tumor necrosis factor α (TNF-α) biologic agents are used for treating refractory sarcoidosis. However, sarcoidosis-like epithelioid cell granulomas may develop during anti-TNF-α treatment. A 63-year-old man suffering from rheumatoid arthritis was treated with oral methotrexate and methylprednisolone for 4 years. He subsequently started biweekly subcutaneous injections of certolizumab pegol. Three months later, light red follicular papules developed on his chest and they spread over the trunk and bilateral upper arms. Histopathology of a lesion showed a sharply demarcated noncaseating epithelioid cell granuloma with multi-nucleated giant cells in the upper perifollicular area. The follicular papules subsided following discontinuation of certolizumab pegol. Folliculitis-like lichenoid sarcoidosis should be included among the adverse cutaneous reactions of anti-TNF-α treatment.

Abstract
Background Isolated tuberculosis of the spleen has been described occasionally in literature, mostly in immunosuppressed individuals with various risk factors. Sequestration in the spleen makes such Mycobacterium tuberculosis infection difficult to diagnose. This report describes an extremely rare case of isolated splenic tuberculosis in an immunocompetent individual. Case presentation A 26 year old Kenyan male presented with pyrexia of unknown origin, with negative screening tests for bacterial, fungal and parasitic infections. Ziehl–Neelsen staining and GeneXpert tests were negative for M. tuberculosis. Diagnosis of isolated splenic tuberculosis was made on core biopsy of the spleen. The patient initially worsened upon treatment with antituberculous medication attributable to the ‘Paradoxical Reaction’ phenomenon, before making full recovery. Conclusions This case highlights the need to continuously be on the lookout for tuberculosis especially in unusual presentations, including subsequent paradoxical reaction which may be encountered.

Abstract
BACKGROUND Employing the secondary action or adaptative reaction of the organism as therapeutic response, homeopathy uses the treatment by similitude (similia similibus curentur) administering to sick individuals the medicines that caused similar symptoms in healthy individuals. Such homeostatic or paradoxical reaction of the organism is scientifically explained through the rebound effect of drugs, which cause worsening of symptoms after withdrawal of several palliative treatments. Despite promoting an improvement in psoriasis at the beginning of the treatment, modern biological therapies provoke worsening of the psoriasis (rebound psoriasis) after discontinuation of drugs. METHOD Exploratory qualitative review of the literature on the occurrence of the rebound effect with the use of immunomodulatory drugs [T-cell modulating agents and tumor necrosis factor (TNF) inhibitors drugs] in the treatment of psoriasis. RESULTS Several researches indicate the rebound effect as the mechanism of worsening of psoriasis with the use of efalizumab causing the suspension of its marketing authorization in 2009, in view of some severe cases. Other studies also have demonstrated the occurrence of rebound psoriasis with the use of alefacept, etanercept and infliximab. CONCLUSION As well as studied in other classes of drugs, the rebound effect of biologic agents supports the principle of similitude (primary action of the drugs followed by secondary action and opposite of the organism).

Abstract
INTRODUCTION The features of paradoxical reactions (PR) that occurred in non-HIV infected patients are rare and not well known. CASE REPORT The authors reported the case of a 21years old, non-immunocompromised, and HIV negative patient treated for disseminated tuberculosis. PR occurred after 8months after initiation of antituberculous treatment. PR presented as left cervical lymphadenopathy, pulmonary, pleural, costal and spinal location of the tuberculosis. The antituberculous drugs were prolonged. Patient's clinical symptoms improved initially. However, left inguinal lymphadenopathy appeared after 20months of antituberculous therapy. Inguinal lymph node biopsy revealed tuberculous lymphadenitis. The patient has a good compliance to the treatment. The patient was continued on same antituberculous treatment for a total of 28months. The cervical and inguinal lymphadenopathy disappeared and CT scan showed regression of thoracic, abdominal, costal and spinal lesions. CONCLUSION PR during antituberculous treatment must be considered after exclusion of other causes. No consensus on the therapeutic management of this entity has been developed to date.

Abstract
OBJECTIVES The aims of this study were to determine predictive factors of paradoxical reaction in patients with cervical lymph node tuberculosis (TB) and to discuss the therapeutic management of this condition. MATERIALS AND METHODS A retrospective study was performed of 501 patients managed for cervical lymph node TB over a period of 12 years (from January 2000 to December 2011). Statistical data were analyzed using IBM SPSS Statistics version 20.0. RESULTS Paradoxical reaction occurred in 67 patients (13.4%), with a median delay to onset after starting TB treatment of 7 months. Lymph node size ≥3cm and associated extra-lymph node TB were independently associated with paradoxical reaction. Treatment consisted of surgical excision (71.6%), restarting quadruple therapy (10.4%), reintroduction of ethambutol (23.8%), and addition of ciprofloxacin (20.8%); steroids were given in two cases . All patients recovered after an average treatment duration of 14.91±7.03 months. CONCLUSION The occurrence of paradoxical reaction in cervical lymph node TB seems to be predicted by associated extra-lymph node TB and a swelling size ≥3cm. The treatment of paradoxical reaction remains unclear and more randomized trials are necessary to improve its management.

Abstract
BACKGROUND A paradoxical reaction (PR) during anti-tuberculosis treatment is a phenomenon that is poorly studied in immunocompetent children. It is defined as a clinical or radiological worsening of pre-existing tuberculosis (TB) disease. METHODS A retrospective descriptive study of children younger than 14 years of age was performed; these children developed PR during the years 2009 to 2014, following a diagnosis of TB. Demographic characteristics, microbiological results, treatment and outcome data were collected. RESULTS Of 51 children diagnosed with TB, five (9.8%) developed a PR; four of these children had pulmonary TB and the remaining patient had miliary TB with central nervous system involvement. The PR occurred at a median of 42 days (range 23-53 days) after initiating therapy. Corticosteroids were started when PR was suspected, at a median dose of 1mg/kg/day. Clinical and radiological improvement was noted in all cases, with a median clinical regression time of 10.5 days (range 3-15 days) and a median radiological regression time of 45 days (range 26-105 days). No sequelae were described in any patient. CONCLUSIONS PR in immunocompetent children during anti-tuberculosis treatment is not such an unusual reaction. Treatment with corticosteroids may be useful for the resolution of PR.

Abstract
The coalescence of the HIV-1 and tuberculosis (TB) epidemics in Sub-Saharan Africa has had a significant and negative impact on global health. The availability of effective antimicrobial treatment for both HIV-1 (in the form of highly active antiretroviral therapy (HAART)) and TB (with antimycobacterial agents) has the potential to mitigate the associated morbidity and mortality. However, the use of both HAART and antimycobacterial therapy is associated with the development of inflammatory paradoxical syndromes after commencement of therapy. These include paradoxical reactions (PR) and immune reconstitution inflammatory syndromes (IRIS), conditions that complicate mycobacterial disease in HIV seronegative and seropositive individuals. Here, we discuss case definitions for PR and IRIS, and explore how advances in identifying the risk factors and immunopathogenesis of these conditions informs our understanding of their shared underlying pathogenesis. We propose that both PR and IRIS are characterized by the triggering of exaggerated inflammation in a setting of immunocompromise and antigen loading, via the reversal of immunosuppression by HAART and/or antimycobacterials. Further understanding of the molecular basis of this pathogenesis may pave the way for effective immunotherapies for the treatment of PR and IRIS.
