RESUMEN

ABSTRACT: This case emphasizes the value of meticulous observation and regular follow-up of patients receiving rifampicin therapy. The prognosis for complete improvement in renal function in such cases was excellent, with prompt recognition and discontinuation of rifampicin. Teaching patients about these possible adverse effects and encouraging immediate reporting of signs and symptoms are likely to be beneficial because acute kidney injury can manifest itself very quickly after rifampicin is started. Even if renal failure can happen with any dose of rifampicin, primary physicians must have awareness about patients on intermittent or irregular therapy and those who have previously used this medication. It is challenging to determine the prevalence of adverse reactions to common antibiotics where a state- or country-wide reporting system is absent. Along with withdrawal of the causative agent patients were treated with corticosteroids (0.5-1 mg/kg/day) for an average period of 4-12 weeks showing significant recovery of renal function.

RESUMEN

This study aimed to elucidate the regression process of ostium granulomas under the usage of intranasal steroid after primary endoscopic dacryocystorhinostomy (DCR). The authors retrospectively reviewed 57 patients (a total of 72 ostia) who had ostium granulomas after primary endoscopic DCR between 2011 and 2015. Topical intranasal steroid spray was applied in all the patients since postoperative day 1. Adjunctive intralesional triamcinolone acetonide injections were administered for extensive and large-sized granulomas that caused impending ostium blockage. Sequential regression of the ostium granulomas and success rates of DCR were assessed using endoscopic photos. The granulomas completely disappeared in 69 (95.8%) ostia, and the average time interval from the surgery to the disappearance was 6.9 ± 2.8 months. Anatomical and functional surgical success rates were 90.3% and 84.7%, respectively. Intralesional steroid injections for ostium granulomas did not alter the outcomes compared to topical intranasal steroid usage significantly (p = 0.445). In conclusion, we observed that, by continuing the usage of intranasal steroids, ostium granulomas disappear gradually at postoperative 6 months. The intranasal surgical manipulation of granulomas, which results in more mucosal cicatricial change and impedes patient satisfaction, can be successfully avoided.

RESUMEN

Rationale: Sarcoidosis is a granulomatous disorder of unclear cause notable for abnormal elevation of blood and tissue ACE1 (angiotensin converting enzyme 1) levels and activity. ACE1 regulates the renin-angiotensin-aldosterone system (RAAS), the terminal product of which is aldosterone, which selectively engages mineralocorticoid receptors to promote inflammation. Objectives: We sought to determine whether the RAAS promotes sarcoidosis granuloma formation and related inflammatory responses. Methods: Using an established ex vivo model, we first determined whether aldosterone was produced by sarcoidosis granulomas and verified the presence of CYP11B2, the enzyme required for its production. We then evaluated the effects of selective inhibitors of ACE1 (captopril), angiotensin type 1 receptor (losartan), and mineralocorticoid receptors (spironolactone, eplerenone) on granuloma formation, reflected by computer image analysis-generated granuloma area, and selected cytokines incriminated in sarcoidosis pathogenesis. Measurements and Main Results: Aldosterone was spontaneously produced by sarcoidosis peripheral blood mononuclear cells, and both intra- and extracellular levels steadily increased during granuloma formation. In parallel, peripheral blood mononuclear cells were shown to express more CYP11B2 during granuloma formation. Significant inhibition of sarcoidosis granulomas and related cytokines (TNFα, IL-1ß, IFNγ, IL-10) was observed in response to pretreatments with captopril, losartan, spironolactone, or eplerenone, comparable to that of prednisone. Conclusions: The RAAS is intact in sarcoidosis granulomas and contributes significantly to early granuloma formation and to related inflammatory mediator responses, with important implications for clinical management.

RESUMEN

Sarcoidosis is a systemic granulomatous disease characterized by non-caseating epithelioid cell granulomas. One of its immunological hallmarks is the differentiation of CD4 + naïve T cells into Th1/Th17 cells, accompanied by the release of numerous pro-inflammatory cytokines. The TL1A/DR3 signaling pathway plays a crucial role in activating effector lymphocytes, thereby triggering pro-inflammatory responses. The primary aim of this investigation was to scrutinize the impact of anti-TL1A monoclonal antibody on the dysregulation of Th1/Th17 cells and granuloma formation in sarcoidosis. Initially, the abnormal activation of the TL1A/DR3 signaling pathway in pulmonary tissues of sarcoidosis patients was confirmed using qPCR and immunohistochemistry techniques. Subsequently, employing a murine model of sarcoidosis, the inhibitory effects of anti-TL1A monoclonal antibody on the TL1A/DR3 signaling pathway in sarcoidosis were investigated through qPCR, immunohistochemistry, and Western blot experiments. The influence of anti-TL1A monoclonal antibody on granulomas was assessed through HE staining, while their effects on sarcoidosis Th1/Th17 cells and associated cytokine mRNA levels were evaluated using flow cytometry and qPCR, respectively. Immunofluorescence and Western blot experiments corroborated the inhibitory effects of anti-TL1A monoclonal antibody on the aberrant activation of the PI3K/AKT signaling pathway in sarcoidosis. The findings of this study indicate that the TL1A/DR3 signaling pathway is excessively activated in sarcoidosis. Anti-TL1A monoclonal antibody effectively inhibit this abnormal activation in sarcoidosis, thereby alleviating the dysregulation of Th1/Th17 cells and reducing the formation of pulmonary granulomas. This effect may be associated with the inhibition of the downstream PI3K/AKT signaling pathway. Anti-TL1A monoclonal antibody hold promise as a potential novel therapeutic intervention for sarcoidosis.

RESUMEN

BACKGROUND: Granuloma formation is an uncommon and persistent skin inflammatory condition caused by the injection of dermal fillers. The exact cause of this reaction is not well understood, but it may be associated with irritating components or abnormal immune function. Treating granulomas can be difficult. However, recent research has shown that Janus kinase (JAK) inhibitors hold promise as a potential therapy for refractory granulomatous diseases. OBJECTIVES: The aim was to evaluate the efficacy and safety of tofacitinib as a treatment for granulomas secondary to filler injection and the possible mechanisms were discussed and summarized. METHODS: This study focuses on three cases of patients who experienced granuloma formation after receiving filler injections and were subsequently treated with tofacitinib. The efficacy and safety of the treatment were evaluated using parameters such as photographs and monitoring for any adverse reactions. In addition, a literature review was conducted to explore the underlying mechanisms and potential effects of tofacitinib. RESULTS: All three cases recovered from swelling and nodules without side effects through the off-label use of oral tofacitinib. Existing data review reveals some approaches for cutaneous granulomatous disorders like inhibiting macrophage activation and downregulation of the JAK-STAT pathway. CONCLUSION: This report emphasizes the effectiveness of JAK inhibitors in treating granulomas caused by filler injections. Recent advancements in understanding the underlying mechanisms of granulomatous reactions have paved the way for JAK inhibitors to be regarded as a promising treatment choice. However, further research is necessary to fully assess the safety and long-term effectiveness of using tofacitinib for granuloma treatment.

RESUMEN

Cartilage hypoplasia syndrome is a primary immunodeficiency disease characterized by short stature, hypoplastic hair and a variable degree of immunodeficiency. Noninfectious cutaneous granulomas represent an uncommon yet well-recognized manifestation within the spectrum of primary immunodeficiency diseases. However, cutaneous granulomas as a manifestation of cartilage-hair hypoplasia syndrome, are extremely rare. We present a case of a middle-aged man with cartilage hypoplasia syndrome featuring cutaneous granulomas, manifesting as chronic, extensive and deep cutaneous ulcers. The patient was treated with anti-TNF-alpha adalimumab with partial improvement. Our case underscores the broad spectrum of clinical manifestations associated with cartilage hypoplasia syndrome and adds new evidence to the potential therapeutic efficacy of anti-TNF-alpha drugs in its treatment.

RESUMEN

Candidal granuloma is an uncommon type of deep chronic cutaneous candidiasis. Candida albican is the most common causative pathogen for candidal granuloma. We report herein the original case of a 69-year-old Chinese woman presented with a 3-year of painful cutaneous lesion on the back of left hand. Physical examination revealed a 4 × 5 cm large infiltrative reddish plaque with unclear boundaries. The yellow-white crusts were observed on the uneven surface of plaque. Histopathological examination of biopsy tissue revealed that yeast cells and the horizontal section of hyphae in the dermis by hematoxylin eosin staining and periodic acid-Schiff staining. Finally, the pathogen was identified as Candida parapsilosis by mycological examination and molecular identification. The patient was treated with itraconazole oral 200 mg twice daily combined with topical terbinafine hydrochloride cream for 2 months. The lesions were fully resolved and no recurrence was observed. Since the cutaneous infection caused by C. parasilosis were rarely reported, we also reviewed all 11 cases of cutaneous infection caused by C. parapsilosis in the PubMed. Our study highlighted that chronic unilateral infiltrated plaques or ulcers should be aware of the occurrence of fungal granuloma including candidal granuloma especially in immunocompromised patients.

RESUMEN

BACKGROUND: Mesotherapy is a popular cosmetic procedure for localized delivery of substances. However, due to the lack of standardized processes, there are potential risks of adverse reactions. Granulomas formation is one of the chronic reactions which impose significant physical and mental burdens on patients. OBJECTIVES: The aim of this analysis is to evaluate the safety and feasibility of combining intense pulsed light (IPL) with intralesional corticosteroids for treating noninfectious granulomas after mesotherapy. METHODS: This retrospective observational case series included patients who suffer from noninfectious granulomas after mesotherapy and received combination of IPL and intralesional corticosteroids treatment between October 2021 and December 2022 at Peking University Shenzhen Hospital, Shenzhen, China. The process and effect were analyzed and summarized. RESULTS: Among the seven patients, five expressed extreme satisfaction with the efficacy, while two was slightly satisfied. The physicians believed that all patients had shown significant improvement. No adverse reactions or recurrences were observed during follow-up. CONCLUSION: Based on this analysis, the application of the combined treatment in patients suffering from noninfectious granuloma due to mesotherapy demonstrates good clinical efficacy and safety, making it worth considering as a treatment option.

RESUMEN

A 12-year-old male eclectus parrot (Eclectus roratus) was referred for evaluation of coelomic distention. Computed tomography and blood work revealed coelomic effusion with free coelomic mineral-attenuating material and elevations in the bile acids and aspartate aminotransferase activity, respectively. Coelomic effusion was consistent with macrophagic inflammation with abundant intracellular lipids. Initial treatment with meloxicam resulted in minimal patient improvement. Disseminated xanthogranulomatous inflammation was suspected based on imaging and diagnostic laboratory results, which were consistent with those previously reported. Biopsy samples of liver tissue and intracoelomic masses confirmed this diagnosis. Treatment was initiated with prednisolone 1 mg/kg/d for 6 months, followed by 0.5 mg/kg/d for 3 months. Clinical improvement was assessed based on owner evaluation, plasma bile acid concentrations, and repeated computed tomographic scans. After 2 months of treatment, the owner reported improved behavior and appetite; this persisted throughout treatment and when the bird was reexamined 17 months following the cessation of steroid therapy. Bile acid concentrations were normal 10 months after the prednisolone therapy was discontinued. Diagnostic imaging showed minimal coelomic effusion 10 months after the last prednisolone dose was administered, with improved ventilation of the air sacs and static to improved dystrophic mineral foci. This report describes the antemortem diagnosis and treatment of disseminated coelomic xanthogranulomatous disease in a psittacine species, with an observed measurable therapeutic response.

RESUMEN

BACKGROUND: Idiopathic aseptic facial granuloma (IAFG) is an underrecognized pediatric skin disease, currently considered within the spectrum of rosacea. It usually manifests as a solitary, reddish, asymptomatic nodule on the cheek that resolves spontaneously. METHODS: Retrospective and descriptive observational study of 43 pediatric patients with a clinical diagnosis of IAFG, followed between 2004 and 2022, at two general hospitals in Argentina. RESULTS: IAFG predominated in girls (65%) and the average age of onset was about 6 years. A single asymptomatic nodule was seen in 79% of patients. The most common localization was the cheek (58%) followed by lower eyelids (41%). Family history of rosacea was present in 16% of patients. A concomitant diagnosis of rosacea and periorificial dermatitis was made in 14% and 9% of our population, respectively. Past or present history of chalazia was detected in 42% of the children. IAFG diagnosis was mainly clinical (88% of cases). Oral antibiotics were the most common indicated treatment (84%). Complete healing was achieved by the majority, but 18% of those with eyelid compromise healed with scars. CONCLUSIONS: IAFG is a benign pediatric condition that physicians should recognize in order to manage correctly. We herein refer to a particular morphologic aspect of IAFG lesions affecting the lower eyelids, where nodules adopt a linear distribution and have a higher probability of involute leaving a scar. Also, we consider that the concomitant findings of rosacea, periorificial dermatitis and chalazia in our patients, reinforce the consideration of IAFG within the spectrum of rosacea.

RESUMEN

Schistosomiasis afflicts approximately 120 million individuals globally. The hepatic pathology that occurs due to egg-induced granuloma and fibrosis is commonly attributed to this condition. However, there is currently no efficacious treatment available for either of these conditions.Our study aimed to investigate the potential antifibrotic and antiparasitic properties of different doses of gallic acid (GA) in experimental schistosomiasis mansoni. In addition, we investigated the outcomes of co-administering it with the standard anti-schistosomiasis treatment, praziquantel (PZQ).In experiment I, Schistosoma mansoni-infected mice were administered GA at doses of 10, 20, or 40 mg/kg. Their effectiveness was evaluated through parasitological (worm and egg loads, granuloma number and diameter), pathological (fibrosis percentage and H-score of hepatic stellate cells (HSCs)), and functional (liver enzymes) tests. In experiment II, we investigated the optimal dosage that yielded the best outcomes. This dosage was administered in conjunction with PZQ and was evaluated regarding the parasitological, pathological, functional, and immunological (fibrosis-regulating cytokines) activities.Our findings indicate that the administration of 40 mg/kg GA exhibited the highest level of effectiveness in experiment I. In experiment II, it exhibited lower antiparasitic efficacy in comparison to PZQ. However, it surpassed PZQ in other tests. It showed enhanced outcomes when combined with PZQ.In conclusion, our findings reveal that GA only slightly increased the antischistosomal activity of PZQ. However, it was linked to decreased fibrosis, particularly when administrated with PZQ. Our pilot study identifies GA as a natural antifibrotic agent, which could be administered with PZQ to mitigate the development of fibrosis.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: "Snow-white waterlily" (Nymphaea candida) dried flower possesses various efficacy in Uighur medicine such as reducing fever and nourishing the liver, anti-inflammatory and cough relieving, moistening the throat and quenching thirst. AIM OF THE STUDY: Polyphenols are characteristic component of N. candida as well as its quality markers, and the purpose of this study was to conduct investigations into anti-inflammatory, antitussive, antipyretic, and analgesic activities of the polyphenol-enriched fraction from N. candida (NCTP) in order to validate the traditional efficacy of this plant. MATERIALS AND METHODS: The polyphenols in NCTP were analyzed by HPLC, and an acute oral toxicity study was conducted for NCTP. The anti-inflammatory activities of NCTP were evaluated using xylene induced ear edema, capillary permeability, cotton pellet granuloma, and carrageenan-induced rat paw edema, of which multiple biochemical indices were measured in carrageenan-induced rat paw edema such as prostaglandin E2 (PGE2), cyclooxygenase-2 (COX-2),5-lipoxygenase (5-LOX), interleukin-6 (IL-6), interleukin-1ß (IL-1ß), tumor necrosis factor-α (TNF-α), malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione (GSH) activities; the analgesic activities were investigated using acetic acid writhing, hot plate test, and formalin test; the anti-tussive and antipyretic effects were tested by ammonia induced cough in mice and yeast-induced fever respectively. RESULTS: NCTP with LD50 of 5222 mg/kg was low toxicity and safety. NCTP (200 mg/kg) could significantly reduce ear swelling and capillary permeability by 30.63% and 31.37%, respectively. NCTP revealed 15.76% inhibiting activities in cotton pellet granuloma in mice at a dosage of 200 mg/kg. Furthermore, NCTP (50, 100, and 200 mg/kg) substantially decreased carrageenin-induced paw edema in rats between 1 and 5 h, and NCTP could decrease PGE2, 5-LOX, COX-2 levels as well as IL-6, IL-1ß, TNF-α activities compared with the control group; NCTP could decrease MDA contents in carrageenin-induced rise, and increase SOD and GSH activities. Furthermore, the dose-dependent inhibition effect of NCTP on pain was revealed in the hot plate experiment. In addition to reducing the amount of writhes brought on by acetic acid, NCTP (50, 100, and 200 mg/kg) significantly inhibited pain latency against both stages of the formalin test. Moreover, NCTP (50, 100, 200 mg/kg) showed the better antitussive activities in mice in a dose-dependent manner. In the yeast-induced pyrexia test, dosages of 50, 100, and 200 mg/kg resulted in a statistically significant drop in rectal temperature. CONCLUSION: The experimental results proved the analgesic, anti-inflammatory, anti-tussive and antipyretic activities of the polyphenol-enriched fraction from N. candida, and supported the traditional use of this plant as well.

RESUMEN

Granulomatosis with polyangiitis (GPA) is a pauci-immune small vessel vasculitis characterised by neutrophil-mediated vasculitis and granuloma. The presence of intracranial parenchymal space-occupying lesions is rarely seen in GPA patients. In this manuscript, we report a case of GPA with granuloma of the fourth ventricle accompanied by obstructive hydrocephalus. Treatment with glucocorticoids (GCs) and multiple immunosuppressants cyclophosphamide (CYC), mycophenolate mofetil (MMF), and rituximab (RTX) showed poor efficacy in this case. After removal of the granuloma by craniotomy, GPA relapsed within 3 months. Under the premise of GC and MMF treatment combined with intrathecal injection of dexamethasone (DXM) and methotrexate (MTX), the intracranial granuloma gradually shrank, and the patient's general condition was alleviated, showing that this is an effective treatment method. Key Points • To date, there are few reports of granulomatous vasculitis combined with granuloma of the fourth ventricle, and our case is the second. • In this case, multiple immunosuppressants and rituximab were ineffective treatments, and the intracranial granuloma was effectively controlled by intrathecal injection of dexamethasone (DXM) and methotrexate (MTX). • Based on this report, it can be suggested that intrathecal injection is effective in treating patients with GPA and central nervous system involvement, but large-scale sample studies are needed.
