Long-term results of 10 years of observation of cured cases of pulmonary tuberculosis

Published on: 23rd September, 2022

Aim of the study: Conduct long-term monitoring of recovered patients with pulmonary TB and study the frequency of relapses of pulmonary TB and factors contributing to their development in the Republic of Tajikistan.Material and research methods: Of the total number of patients with pulmonary TB, 820 people in 2010-2011 after successful treatment, were transferred for further dispensary observation to PHC facilities, whose health status we monitored for 10 years (including 2020). Of the 820 patients, we were able to track the health status for 10 years in 622 patients (320 men and 302 women, age groups 19-44 years old - 330 people and 45-69 years old - 292 people). The rest - for various reasons were lost from further dispensary observation. All patients in PHC facilities annually during the period of dispensary observation underwent clinical, instrumental, laboratory, and X-ray examinations to exclude the recurrence of TB. Data for each patient were tracked using the National TB Registry OpenMRS data.Research results: The elimination of preventive anti-relapse measures in people with residual post-tuberculosis changes in the lungs led to an increase in the number of relapses of the disease. The analysis of the conducted studies shows that the incidence of relapses of pulmonary TB does not depend on the regions and the severity of TB burden, they often develop with insufficient follow-up after the end of treatment and inadequate preventive measures in dispensaries patients.The study of the reasons for the development of relapses makes it possible to timely identify a group of patients who need anti-relapse measures and prolongation of dispensary observation.Conclusion: Thus, the results of this observation revealed the occurrence of relapses within 10 years in 19.3% of cases. A retrospective analysis of the initial forms of the disease showed that relapses of pulmonary tuberculosis occurred more often in patients who had had fibrous-cavernous pulmonary tuberculosis, than in patients who had disseminated pulmonary TB, and less often after suffering infiltrative pulmonary TB. Relapses of the disease occurred more often in men aged 19-44 years. The results obtained indicate the development of relapses of pulmonary tuberculosis has a statistically significant dependence on the form of the initial disease, the presence of RPTCL, comorbid diseases such as HIV, diabetes mellitus, COPD, and the regularity of taking anti-TB drugs. At the same time, it turned out that the social status of all patients with relapses corresponds to the level of poverty, which should also be taken into account.

Idiopathic progressive polyneuropathy presented with frequently acute pulmonary oedema: a case report

Published on: 29th September, 2022

Neuropathy is when nerve damage interferes with the functioning of the peripheral nervous system (PNS). When the cause can’t be determined, it’s called idiopathic neuropathy(Idiopathic neuropathy, now designated as chronic idiopathic axonal polyneuropathy (CIAP).There are three kinds of nerves within the PNS. Sensory nerves relay messages from the sense organs to the brain. This allows sensations of temperature and touch. Motor nerves transmit signals from the brain to the muscles. This helps the brain control the muscles. Autonomic nerves control body functions like heart rate, breathing, and digestion.Damage to nerve cells can affect how the PNS communicates with the rest of the body. Symptoms can include numbness, pain, and balance issues.It’s called acute neuropathy when symptoms develop suddenly. Alternately, it’s called chronic neuropathy when symptoms start slowly and increase over time. Diagnosis involves physical examination and review of medical history. Diagnostic testing may include blood tests, nerve testing, and imaging tests.There is no cure for idiopathic neuropathy. Treatments including medication, physical therapy, and lifestyle modifications can help you function and feel better.We report a case of idiopathic polyneuropathy presented with frequent acute pulmonary edema for a year.

Chronic thromboembolic pulmonary hypertension resulting in decompensated right heart failure

Published on: 24th November, 2022

Chronic thromboembolic pulmonary hypertension is a notoriously underdiagnosed cause of severe pulmonary hypertension. It is a form of precapillary pulmonary hypertension (PH) that results from intraluminal thrombus organization and fibrous formation which ultimately results in the complete obliteration of pulmonary arteries, resulting in increased pulmonary vascular resistance which leads to the development of pulmonary hypertension and as a result right heart failure. The mechanism involves the narrowing of the pulmonary artery which increases blood pressure within the lungs and impairs blood flow which increases the workload of the right side of the heart ultimately causing right heart failure. Pulmonary hypertension can also cause arrhythmias, blood clots, and bleeding in the lungs. Even though CTEPH is a deadly condition, among all forms of pulmonary hypertension, CTEPH is the only curable form. Echocardiography is the initial assessment tool for suspected PH. A right heart catheterization may be performed to confirm the presence of pulmonary hypertension. Confirmation of CTEPH requires a V/Q scan. Although ventilation/perfusion scintigraphy has a major role in the evaluation of patients with suspected CTEPH, nowadays CTA chest is being used widely as it produces much better-quality images compared to V/Q scan. Without treatment, the prognosis is very poor. Out of three treatment modalities such as; pulmonary endarterectomy (PEA) surgery, balloon pulmonary angioplasty (BPA), and medical therapy, surgery is the gold standard. The physician must be familiar with the disease entity, early diagnosis, and appropriate treatment to improve survival. Here we present a literature review on this topic.

Pulmonary congenital cystic adenomatoid malformation: a rare congenital abnormality in adults and review of literature

Published on: 25th November, 2022

Congenital cystic adenomatoid malformation of the lung (CCAM) is characterized by an adenomatoid proliferation of bronchiole-like structures and cysts formation. The condition is most commonly found in newborns and children and may be associated with other malformations; rarely, the presentation is delayed until adulthood. We herein report two cases of CCAM in adult patients. 22 years old healthy female with pre-employment health screening chest x-Ray showed a lesion in the upper lobe of the right lung. In another case, a computed tomographic scan of the thorax (CT) confirmed a mass in the upper right lung. A 28-year-old male presented with recurrent respiratory tract infection resistant to antimicrobial therapy. CT scan of the thorax showed a mass in the left lung upper zone. Surgical resection was performed in both cases, and histopathology of the resected specimen showed both cases were consistent with the CCAM.

Pulmonary edema ex vacuo or unilateral shock lung: a case report

Published on: 30th November, -0001

Pulmonary edema is a rare but potentially life-threatening iatrogenic complication after treatment through therapeutic thoracentesis of a collapsed lung due to a hydro- or pneumo-thorax. We present a case of a 25-years male, without any pathological antecedents, who went to our emergency services with dyspnoea, tachypnea, and hypoxemia. The final diagnosis made after a clinical examination and chest X-ray showed a complete collapse of the right lung due to spontaneous pneumothorax [1-3] (Figure 1).

A case of allergic bronchopulmonary aspergillosis complicated by nocardiosis and staphylococcus aureus infection

Published on: 19th December, 2022

Nocardia is a ubiquitous organism and often causes serious fatal infections in immuno-compromised individuals. Staphylococcus aureus infection stimulates an inflammatory response that causes lung damage and facilitates subsequent chronic infection. Patients of allergic bronchopulmonary aspergillosis (ABPA) on steroids and immunosuppressants are particularly at risk of these infections. We present the case of a middle-aged man who was diagnosed to have ABPA by serological and radiographic criteria. He presented with fever, cough, and mucopurulent sputum. Subsequent sputum culture for bacteria and fungus revealed the growth of Staphylococcus aureus and Nocardia spp. respectively.

Coronary artery anomalies, myocardial bridging associated with fistula to pulmonary artery trunk. Case reports

Published on: 31st March, 2023

Between coronary artery anomalies, myocardial bridging means an epicardial coronary artery, mostly left anterior descending artery (LAD), running through an intramyocardial “tunnel” (usually in the middle segment), leading during systolic contraction, flow reduction, through the vessel. When this anomaly is associated with a coronary fistula, which “steals” more from the bloodstream, the symptoms are more pronounced, and the management complex is surgical in particular. Despite the presence from birth remains asymptomatic and it becomes clinically manifest later in the third to fourth decade of life, with a diverse palette of symptoms; angina, arrhythmias, and acute myocardial infarction up to sudden death. Diagnosis and particular management, medical, interventional, and surgical should avoid major cardiac complications and sudden death. We present two adult patients, with coronary artery bridging, one case associated with coronary artery fistula, LAD to pulmonary artery trunk, very symptomatic with surgical management, and the second only myocardial bridging controlled with medication and supervision.

The Predictive Value of Diaphragm Thickness Fraction on Postoperative Pulmonary Complications after Digestive Cancer Curative Surgery

Published on: 14th August, 2023

Background: Postoperative Pulmonary Complications (PPCs) escalate mortality, hospitalization, and costs. This study aimed to predict PPCs after curative digestive cancer surgery using thickness fraction (TFdi) determined by ultrasonography. Methods: A prospective study was conducted over a period of 9 months. Diaphragmatic ultrasound was performed pre-surgery and repeated postoperatively (within 24 hours of ICU admission, then day 3). Right and left hemidiaphragm thickness at end-expiration (TEE) and peak-inspiration (TPI) were measured using ultrasonography. The maximal diaphragm thickening fraction during inspiration (TFdi,max) was calculated: TFdi,max = (TPI–TEE)/TEE. Patients were classified into No-PPCs and PPCs groups. Results: 159 patients participated, 55 (34.6%) developed PPCs. ICU stay was longer in PPCs patients with more deaths. TFdi,max decreased postoperatively and remained lower in PPCs patients [44.83% ± 11.07 vs. 31.54% ± 8.45; p < 0.001]. The receiver operating characteristic curve yielded an area under the curve of 0.83 [95% IC: 0.754 – 0.887]. TFdi,max < 37% had 72.7% sensitivity (95% IC: 59.0% – 83.8%) and 80.8% specificity (95% IC: 71.8% – 87.8%), Positive and negative Likelihood Ratios were 3.7 (95% IC: 2.4 – 5.7) and 0.3 (95% IC:0.2 – 0.5), respectively. In multiple logistic regression, preoperative risk factors for PPCs included TFdi,max < 37% [OR: 7.10; 95% CI: 1.71 – 18.60; p < 0.001] and supramesocolic surgery [OR: 9.94; 95% CI: 3.62 – 27.29; p < 0.001]. Epidural administration was protective [OR: 0.21; 95% CI: 0.052 – 0.87; p = 0.031]. Conclusion: A low preoperative TFdi,max identifies high-risk PPCs patients after digestive cancer surgery, aiding targeted preventive strategies like inspiratory muscle preoperative training.

Cardiac Tamponade as the Cause of Pulmonary Edema: Case Report

Published on: 17th August, 2023

Introduction: Cardiac tamponade is an emergency syndrome that requires fast diagnosis and treatment; otherwise patient follows obstructive shock and cardiac arrest. Case report: A 70-year-old female was brought to the emergency department with hypoxemia. She had a history of progressive dyspnea over the past three weeks. Past medical history includes smoking. On physical examination: tachypnea, hypoxemia (SaO2 89%), jugular venous distention, arterial pressure 220/100 mmHg, heart rate rhythmic of 82 bpm. On pulmonary auscultation: diffuse and bilateral crackles. Lung ultrasound showed a bilateral B line and the echocardiogram demonstrated a pericardial effusion with signs of tamponade. A pericardiocentesis evacuated 620 ml of hemorrhagic fluid and the patient was transferred to the intensive care unit, hemodynamically stable, with SaO2 95%. At the ICU the echocardiogram, showed resolution of the cardiac tamponade and a tumor adhered to the lateral wall of the left ventricle. Chest CT demonstrated: a left lung tumor, infiltrating the pericardial sac. A pericardium biopsy demonstrated undifferentiated carcinoma. Discussion: Cardiac tamponade diagnosis requires a high level of suspicion. Respiratory failure, chest pain, and shock, observed in cardiac tamponade, are also present in different diseases. The most common finding of cardiac tamponade is dyspnea (78% of cases). Our patient had dyspnea due to pulmonary edema, secondary to left ventricle diastolic dysfunction caused by the tamponade. A bedside echocardiogram made the diagnosis of cardiac tamponade and guided the effective pericardiocentesis. Conclusion: Cardiac tamponade must be suspected in all cases of acute dyspnea. Echocardiogram is the method of choice for the diagnosis and for guiding the pericardiocentesis.

Hazardous Effects of Malaria for Patients Residing in Low-probability Malaria Areas: A Case Report and Critiques of the Literature for Cerebral Malaria

Published on: 13th September, 2023

Despite decades of global and country commitments towards eradicating malaria, malaria remains the most hazardous parasitic disease and the most common cause of fever for humans, especially in tropical countries. Plasmodium falciparum causes 90% of malaria cases. Coma [Cerebral Malaria (CM)], acidosis, hypoglycemia, severe anemia, renal dysfunction, and pulmonary edema are the most common complications of malaria caused by Plasmodium falciparum and the most common cause of death related to malaria. People from less prevalent malaria areas are at high risk of developing these complications. A 16-year-old male from a low malaria transmission area was diagnosed with CM. Prior to developing CM, he was treated with Coartem. CM is a medical emergency and one of the forms of severe malaria. CM has high mortality and morbidity rates. Yet, international health-related agencies, funders, and policy-makers are unfamiliar with it. The continuous occurrence of CM validates the considerable need for global investment in malaria control and elimination programs. Early administration of Artesunate to all patients suspected of having severe malaria would reduce global malaria-related mortality and morbidity. Simple tests, such as the determination of malaria parasitic density either with thin or thick blood smears, may influence the proper management of all severe malaria cases. However, in clinical practice, the determination of malaria parasitic density is not routinely done. Further commitments are needed to ensure routine determination of malaria parasitic density for all suspected severe malaria cases. Moreover, further commitments are needed to guarantee the proper management of CM because it is a major cause of reversible encephalopathy in tropical countries.

Stable COPD Picture through Exhaled Breath Condensate, Questionnaires and Tests. A Proof of Concept Study

Published on: 5th December, 2023

Background: Changes in lung structures persist in stable Chronic Obstructive Pulmonary Disease (COPD), but their correlation with the clinical picture remains unclear. The purpose of this study was to assess the stable COPD picture via the relationship between exhaled breath condensate (EBC) particle concentration and the Saint George Respiratory Questionnaire (SGRQ), COPD Assessment Test (CAT), and six-minute walking test (6 MWT). Methods: 12 stable COPD and 12 healthy subjects participated in the study. The EBC was collected with Rtube and analyzed using the Accusizer FxNano. Particle concentration was measured and correlated with the findings of the tools used to assess the health status and functional profile of COPD. The results’ analysis was performed with the Spearman’s test and the Mann-Whitney U - test.Results: The COPD group presented a worse picture of health status and functional profile compared to the healthy group. Correlations were observed between components of the SGRQ and CAT. The two groups presented similar levels of EBC particle concentrations, but the number of small particles was higher in COPD subjects. A correlation of the EBC particle concentration with the activity and total score of the SGRQ was only observed in the healthy group. Conclusion: The total particle number was similar in the COPD and healthy groups. A few correlations between the EBC particles and tools used were also observed. The use of EBC particle concentration to monitor COPD status cannot be claimed with confidence because of the small sample size. Further research is necessary, particularly in large-scale groups.

A Perplexing Case of Genito-urinary Tuberculosis in an 83-Year-Old Woman with Increased Levels of Tumor Markers: A Case Report

Published on: 5th December, 2023

Background: Tuberculosis (TB) is a significant global health problem, and extrapulmonary TB can present with no specific clinical or radiographic findings. Genito-urinary TB is often associated with elevated tumor markers and can be misdiagnosed as ovarian/fallopian tube carcinomas, especially in elderly female patients, as genitourinary TB commonly affects women of reproductive age.Objective: We present a rare case of genito-urinary TB in an elderly female patient who was initially misdiagnosed with ovarian cancer with metastasis.Case presentation: An 83-year-old woman with a medical history of diabetes and hypertension presented with complaints of abdominal distension. Diagnostic imaging revealed lesions in the ovaries and omentum and tumor markers were elevated, leading to a suspicion of ovarian cancer with metastases to the omentum. The patient underwent a diagnostic laparotomy and surgical removal of ovaries, fallopian tubes, and the lesion of the greater omentum. However, no malignancy was found during the morphological evaluation. Further histopathological examination confirmed the final diagnosis of genito-urinary tuberculosis, and the patient received anti-TB drugs. The postoperative period was uneventful, and tumor marker levels decreased.Conclusion: As the clinical presentation of genito-urinary TB can mimic ovarian cancer, a histopathological examination should be performed for differential diagnosis, thereby reducing the possibility of inaccurate treatment. This case report highlights the importance of considering genito-urinary TB as a differential diagnosis in elderly female patients presenting with elevated tumor markers, abdominal distension, and suspected genital malignancy. It is crucial to carefully evaluate these cases and explore the possibility of genital TB as an alternative diagnosis, given the overlapping clinical presentation. This highlights the importance of a comprehensive diagnostic approach that includes considering TB in addition to malignancy, even in the context of elderly female patients.

Delayed Diagnosis of Early-onset Sarcoidosis: A Case Report and Literature Review

Published on: 18th January, 2024

Background: Early-onset sarcoidosis is a rare systemic inflammatory granulomatous disease, distinguished by onset before the age of 4 and notably lacking pulmonary involvement. Unfortunately, the condition often shows clinical features similar to juvenile idiopathic arthritis, resulting in the misdiagnosis of numerous patients. This case report delves into the challenges associated with the delayed diagnosis of early-onset sarcoidosis, with a particular focus on the diagnostic methods employed to address this delayed recognition.Case presentation: A 15-year-old girl presented with a history of recurrent fever since infancy, accompanied by rash, arthritis, and joint deformity. Previously misdiagnosed with juvenile idiopathic arthritis, she underwent management with steroids and methotrexate, yielding no improvement. The diagnosis of early-onset sarcoidosis was made during adolescence based on serial examinations, comprehensive laboratory and radiological evaluations, and subsequent histopathology findings. Presently, the patient is receiving treatment with low-dose steroids and biologic therapy (Tocilizumab) and experiencing no disease progression.Conclusion: This case report underscores the importance of considering early-onset sarcoidosis in the differential diagnosis of pediatric patients exhibiting persistent arthritis from an early age. Early detection and treatment are crucial in averting complications and enhancing the overall quality of life.

Effect of Azithromycin on Lung Function and Pulmonary Exacerbations in Children with Post-infectious Bronchiolitis Obliterans. A Double-blind, Placebo-controlled Trial

Published on: 28th February, 2024

Introduction: Acute lower respiratory infection (ALRI) of viral etiology is a frequent consultation in pediatrics. Post-infectious bronchiolitis obliterans (PIBO) is a rare and potentially severe disorder following ALRI, characterized by partial or complete obstruction of the small airways by inflammatory tissue. There is evidence that macrolides reduce morbidity and mortality in diffuse panbronchiolitis, which may have similar inflammatory and obstructive components.We hypothesized that the effect of azithromycin (AZ) may improve lung function and reduce pulmonary exacerbations in PIBO.MethodsStudy design: A double-blind, randomized, placebo-controlled trial.Patients: We enrolled patients with PIBO followed-up at the Pulmonology department between 5 years to 18 years.Treatment regimen: The patients were randomized to receive active drug or placebo three times a week. Clinical evaluation: Clinical evaluation, pulse oximetry, lung function, and 6-min walk test were performed before and after study initiation and at 1, 3, and 6 months.CT scan and a quality of life questionnaire were performed at the beginning and the end of the Study.Results: 29 patients, 15 in G1 (10 males) and 14 in G2 (7 males) were included.There were no significant differences in FVC, FEV1, TLC, RV, or sGaw between the treatment group and controls. In addition, no significant differences were observed in exacerbations, quality of life questionnaire, or HRCT scan scores.Conclusion: No differences were observed between the groups. Further studies are necessary to allow us to find a better treatment, as azithromycin does not seem to be efficacious.

Why is Pain not Characteristic of Inflammation of the Lung Tissue?

Published on: 7th March, 2024

The article presents materials that make it possible to understand the reason for the absence of one of the classic signs of inflammatory processes in patients with acute pneumonia. The peculiarities of the functional significance of the lungs for the body are the reason that in the case of inflammation in the tissues of the organ, nature has provided for the presence of a more important adaptive mechanism instead of pain as a signal sign. Understanding the causes of the absence of pain in pneumonia in the initial period, which is most responsible for timely and effective care for these patients, allows us to look at the pathogenesis of the disease from a new point of view, which is of fundamental importance for the correction and selection of pathogenetic means of care.

Effect of TAK242 on MCP-1 and TGF-β in COPD Rats

Published on: 13th March, 2024

Objective: To investigate the mechanism of MCP-1 and TGF-β regulation by TAK242 in COPD rats. Methods: Thirty-six SD rats were randomly divided into normal, COPD control, and TAK242 groups. The normal group was freely fed, and the other groups used the method of fumigation plus lipopolysaccharide tracheal drip to establish an experimental animal model of COPD. After successful modeling, each experimental group received 0.9% NaCl solution and corresponding drugs by intraperitoneal injection for 7 d. After drug administration, lung function was examined; pathological changes in lung tissue were observed by light microscopy with hematoxylin-eosin staining; mRNA expression of MCP-1 and TGF-β was detected by q-PCR; and protein expression of MCP-1 and TGF-β in lung tissue was detected by Western blot and IHC, TGF-β protein expression in rat lung tissue. Results: Compared with the normal group, rats in the COPD control group showed signs and symptoms of COPD, decreased lung function, and increased expression of MCP-1 and TGF-β. The TAK242 group showed decreased expression of MCP-1 and TGF-β compared to the COPD control group. Conclusion: MCP-1, and TGF-β played a crucial role in the early stage of COPD fibrosis. TAK242 could ameliorate airway inflammation and inhibit the progression of COPD lung fibrosis in pre-existing rats in COPD model rats.

Longitudinal Risk Phenotyping in Incident Systemic Sclerosis-associated Pulmonary Arterial Hypertension (SSc-PAH): An Unsupervised Cluster Analysis of the PHAROS Registry

Published on: 15th March, 2024

Background: Systemic sclerosis-associated pulmonary arterial hypertension (SSc-PAH) is characterized by pulmonary arterial remodeling resulting in right ventricular failure and death if untreated. Despite therapeutic advances, there is survival variability within the SSc-PAH population. The aim of this study was to delineate high-risk subgroups of SSc-PAH using readily available clinical parameters.Methods: We analyzed data from the PHAROS database, a prospective observational registry of incident SSc-PAH patients. Latent class modeling was performed based on trends in 6MWD over time. We compared survival between the clusters regarding baseline clinical parameters and changes in these parameters over time.Results: We identified four unique groups within 103 patients meeting our inclusion criteria, based on trajectories of 6MWD. Patients in Cluster 4 exhibited a decline in 6MWD over time and had the worst prognosis with a median survival of 3 years. Patients in Cluster 3, with the lowest baseline 6MWD, were associated with lower median survival (5 years) when compared to Clusters 1 and 2 (> 9 and 7 years, respectively), despite an improvement in 6MWD over time. There were no meaningful changes in SF-36 and WHO functional class between the clusters, but BNP trended higher over time in the higher-risk clusters. Conclusion: We identified high-risk subsets of SSc-PAH characterized by significantly worse survival. Incident SSc-PAH patients with a decline in 6MWD over time or low baseline 6MWD had worse survival when compared to SSc-PAH patients who demonstrated relatively stable or mild reduction in 6MWD over time.

Macitentan in Adults with Sickle Cell Disease and Pulmonary Hypertension: A Proof-of-Concept Study

Published on: 22nd April, 2024

Pulmonary hypertension (PH) in sickle cell disease (SCD) is associated with a mortality rate of 37%. There is an upregulation of adhesion molecules which leads to the expression of endothelin-1, a potent vasoconstrictor. A prospective, descriptive study was done to determine the safety and efficacy of macitentan in patients with SCD and PH. Continuous variables were reported as mean ± SEM or percentage where appropriate. We screened 13 patients and recruited five. All five patients were adults. Data were analyzed as appropriate by student t - test. Statistical significance was assumed at p < 0.05. Baseline pulmonary hemodynamics obtained by right heart catheterization and systemic hemodynamics were (± SEM): mean pulmonary artery pressure (MPAP) 32 ± 8 mmHg, right atrial pressure (RAP) 9 ± 4 mmHg, pulmonary vascular resistance (PVR) 257 dynes-sec/cm5 and CI 3·7 ± 0.39 l/m2. Of all parameters, only PVR and 6-min walk distance changed significantly. For the group, MPAP decreased by 15.6%, PVR by 22.5% and RAP by 25.5%. The 6-minute walk distance increased over sixteen weeks except in Patient 4 who had a 3% decrease. The mean walk distance increased in the total distance, from 464 ± 158 meters to 477 ± 190 meters (p .123). In four patients, the adverse events were mild to moderate and did not lead to study drug discontinuation. Significant improvement in pulmonary hemodynamics and exercise capacity in patients with SCD-related pulmonary arterial hypertension. We found that macitentan was safe and well tolerated.

An Interesting Case of COPD Exacerbation Presenting with Mixed Features of Intracranial Hypertension and Hypercapnic Encephalopathy

Published on: 2nd July, 2024

Background: Idiopathic intracranial hypertension (IIH or pseudotumor cerebri) has two major morbidities: papilledema with visual loss and disabling headache. Intracranial Venous Hypertension (IVH) is a fundamental mechanism of IIH. Although traditionally considered limiting to the central nervous system, evidence suggests IIH as a systemic disease associated with cardiorespiratory disorders, which has been far less comprehended. Case Report: A 60-year-old female with Chronic Obstructive Pulmonary Disease (COPD) was admitted for dyspnea and developed a coma with a pH of 7.01 and pCO2 of 158 mmHg. She was intubated and had persistent nuchal rigidity, a brief myoclonus episode with a negative electroencephalogram, and negative CT head studies. A Lumbar Puncture (LP) revealed elevated opening pressure (35 cmH2O) with normal Cerebral Spinal Fluid (CSF) studies. Her nuchal rigidity improved after the removal of 40 mL CSF. The ophthalmology examination the next day after her the large volume LP didn’t show visual loss or papilledema. The patient improved clinically and was extubated two days later. Her echocardiogram showed a dilated right ventricle with pulmonary hypertension. The patient was discharged home.Discussion: IIH is different from hypercapnic encephalopathy and characterized by increased intracranial pressure with papilledema, vision loss, and debilitating headache. Hypercapnia-induced increased intracranial venous flow and pulmonary hypertension-caused elevated central venous pressure with consequent outflow resistance lead to IVH. In hypercapnic encephalopathy, the presentation is mostly cognitive changes. In this case, nuchal rigidity with a negative CT head scan triggered the investigation of IIH. Conclusion: A deep understanding of the relationship between COPD and IIH is vital. There is insufficient evidence to recommend routine eye examinations in COPD patients for papilledema and to conduct a pulmonary function test for a newly diagnosed IIH patient. However, we highly suggest a timely ophthalmology exam prior to performing an LP in COPD patients with suspecting IIH to avoid unnecessary procedures and meanwhile improve clinical outcomes.
