A Case of Metformin-Associated Lactic Acidosis Complicated by Acute Liver Failure, Acute Renal Failure, and Shock.

Metformin is an oral antihyperglycemic agent used for type 2 diabetes mellitus (T2DM) management and is considered to be the first-line treatment for diabetic patients. It works by improving insulin sensitivity, reducing intestinal absorption, and decreasing glucose production in the liver, leading to decreased blood glucose levels. It is generally considered a safe drug; however, it is associated with an uncommon but serious side effect known as metformin-associated lactic acidosis (MALA), a potentially life-threatening condition. Patients with renal failure and liver disease are at high risk of developing MALA; therefore, the medication should be used cautiously in these patients. The diagnosis of MALA requires high suspicion from the physician of this specific entity; otherwise, it may be easily missed. Herein, we report a case of a 63-year-old female with alcoholic liver disease on metformin who was found to have MALA complicated by acute decompensated liver failure, renal failure, and shock.

Transverse Myelitis: An Adverse Reaction to Abatacept.

Immunotherapies are powerful disease-modifying agents in treating autoimmune diseases like rheumatoid arthritis (RA). However, their unique mechanisms of action confer a broad spectrum of immune-related adverse events (irAEs), which tend to be rare but complex, with significant risk for morbidity and mortality. We report a case of transverse myelitis in a patient with RA whose joint disease had been well-controlled with long-term intravenous abatacept. Suspicion of an unusual irAE in this elderly patient, whose neurologic symptomatology was gradual and protracted, prompted the discontinuation of abatacept and the rapid initiation of corticosteroid therapy. These interventions yielded a favorable clinical outcome for the patient. We must draw clinicians' attention to this rare but potentially consequential adverse drug reaction.

Cocaine-Induced Acute Extremity Compartment Syndrome: A Rare Case Report.

There is a dearth of research connecting acute extremities compartment syndrome to cocaine. Here, we present a case of a forty-year-old guy who is actively using cocaine and comes to the emergency room with excruciating right leg pain and swelling. Physical examination revealed substantial tachycardia, lack of dorsalis pedis pulses, stiff and painful calf muscles, and absence of plantar reflexes in the right lower extremities after sleeping on his right leg. A positive urine drug screen for cocaine, severe rhabdomyolysis, and acute renal damage warranted further laboratory testing. A diagnosis of compartment syndrome was established based on the lack of dorsalis pedis pulses in the right lower extremity and radiographic evidence of oedematous alterations in the calf muscles with perimuscular edema. For this case, acute renal injury was done, and treatment with fluid, hemodialysis, and right lower extremity double-compartment fasciotomies have been used. After that, his clinical situation improved, and no other dialysis sessions were required. Cocaine usage has been linked to rhabdomyolysis; nevertheless, compartment syndrome is an extremely uncommon consequence, particularly in the absence of severe damage or extended immobility.

Haemophilus Influenzae Epididymo-Orchitis and Bacteraemia in an Immunocompetent Patient.

Background: Epididymitis is a common cause of scrotal pain in adults, with coliform bacteria being the most common isolated organisms in patients older than 35. Case presentation: A 51-year-old healthy patient presented with scrotal pain and swelling, and was found to have epididymo-orchitis and bacteraemia caused by Haemophilus influenzae, which has not previously been reported as a cause of epididymo-orchitis and bacteraemia in immunocompetent patients. Discussion: Diagnostic studies can help confirm the diagnosis and detect the causative pathogen. In all suspected cases, a urinalysis, urine culture and a urine or urethral swab for nucleic acid amplification tests (NAATs) for Neisseria gonorrhoeae and Chlamydia trachomatis should be performed. Colour Doppler ultrasonography often shows an enlarged thickened epididymis with increased Doppler wave pulsation in epididymitis. H. influenzae are pleomorphic gram-negative rods that commonly colonise the human respiratory tract and are associated with a number of clinical conditions. H. influenzae has been reported as a cause of epididymo-orchitis in prepubertal boys, and in few cases were associated with positive blood cultures. In adults, H. influenzae has been isolated before from urine samples or urethral swabs in patients with epididymitis or epididymo-orchitis. Conclusion: This case highlights the possibility of H. influenzae causing epididymo-orchitis and bacteraemia in immunocompetent patients. Healthcare providers should consider H. influenzae in the differential diagnosis of epididymitis and epididymo-orchitis in both immunocompetent and immunocompromised patients. LEARNING POINTS: H. influenzae can cause epididymo-orchitis and bacteraemia in immunocompetent patients. This has not been previously reported.H. influenzae should be considered in the differential diagnosis of epididymitis and epididymo-orchitis in both immunocompromised and immunocompetent patients.Healthcare providers should be aware of the increasing incidence of epididymitis and epididymo-orchitis caused by non-coliform bacteria in patients older than 35 years, especially in immunocompromised patients.

Baker's Yeast Might not always be Good for Everyone - A Case of Percutaneous Gastrostomy Tube Induced Saccharomyces Cerevisiae Peritonitis in an Immunocompromised Patient.

Peritonitis, the inflammation of the protective membrane surrounding parts of the abdominal organs, is a common clinical pathology with multifactorial aetiologies. While bacterial infections are well-recognised as a cause of peritonitis, fungal infections remain relatively uncommon especially Saccharomyces cerevisiae, which is commonly used for breadmaking and as a nutritional supplement. This fungus has been reported to induce peritonitis in patients on peritoneal dialysis. However, it has never been reported as secondary to percutaneous endoscopic gastrostomy (PEG) tube insertion in immunocompromised patients. We present a 64-year-old female with a history of human immunodeficiency virus (HIV) who developed S. cerevisiae peritonitis following PEG tube insertion. The case highlights the importance of considering rare organisms when treating immunocompromised patients with peritonitis, especially after gastrointestinal tract penetration or peritoneal membrane disruption. LEARNING POINTS: Fungal infection can be a cause of peritonitis especially in an immunocompromised patient.Saccharomyces cerevisiae can be a pathological organism and induce serious infections.Early recognition of the cause of peritonitis and controlling the source is critical to prevent complications.

Unveiling a Critical Subacute Complication: Right Apical Septum Pacemaker Lead Dislodgement Leading to Right Ventricular Perforation and Minimal Pericardial Effusion.

The implantation of cardiac pacing devices, such as pacemakers and implanted cardioverter-defibrillators (ICDs), has significantly improved patient outcomes in the treatment of a range of cardiac arrhythmias. Right ventricular (RV) pacing lead perforation is an uncommon but potentially dangerous complication that can occur despite technical breakthroughs. RV lead perforation, which can result in right ventricular perforation as well as possible pulmonary or vascular harm, is caused by the pacing lead breaking through the myocardial wall. Despite being rare, this complication warrants attention because of the risks for morbidity and mortality that are involved. We present a case of right ventricular perforation caused by a pacemaker lead and examine the nuances of RV lead perforation in this instance, including its prevalence, clinical presentation, diagnostic difficulties, and treatment strategies, illuminating the many factors to be taken into account while properly managing this issue.

Complicated Treatment Course of Severe Asymptomatic Hypertriglyceridemia: A Case Report and Literature Review.

BACKGROUND Close observation, statins, fibrate treatment, and lifestyle changes can safely manage asymptomatic individuals with severe hypertriglyceridemia (HTG) and minimal risk of symptom development. However, the risk of medication-induced liver injury in patients taking statin-fibrate makes management more challenging, and may require hospital admission and close monitoring with follow-up. CASE REPORT We present a rare case of a 43-year-old man with asymptomatic severe HTG exceeding 11.370 mg/dL with mixed hyperlipidemia, managed initially with high-intensity statins and fibrate. However, due to the concurrent use of statin and fibrates, the patient subsequently developed an acute liver injury. Hence, the oral medications had to be stopped, and the patient was admitted to the hospital for an insulin drip. Even during the hospital course, the patient's triglyceride (TG) levels showed resistance to the recommended dose of insulin and he required a higher insulin dose. He was discharged on fenofibrate and subcutaneous insulin to keep the TG level under 500. Fibrate was stopped, and high-intensity statin was used as primary prevention with lifestyle modifications. CONCLUSIONS This instance highlights the necessity of increased cognizance and cooperative endeavors in handling severe asymptomatic HTG. Our results highlight the significance of further research into the management of severe asymptomatic HTG in cases of injury to the liver. This work adds essential knowledge to the ongoing discussion about managing a rare case complicated by acute liver injury.

A Rare Occurrence of Spontaneous Coronary Artery Dissection in Elderly: Diagnostic Challenges and Clinical Implications.

Spontaneous coronary artery dissection (SCAD) is the ripping of the epicardial coronary artery wall without any trauma, coronary procedures, or rupture of atherosclerotic plaque. Intimal rip, intramural hematoma, and false lumen formation are the hallmarks of this disease, which may result in coronary blood flow obstruction and myocardial ischemia. The role of SCAD in acute coronary syndrome (ACS), and sudden death has come to light more and more, particularly in young females and those with few typical atherosclerotic risk factors. This study details a 65-year-old female with a history of hypertension, hyperlipidemia, asthma, and chronic kidney disease who presented with severe chest pain and elevated troponin levels. Upon investigation, spontaneous dissection of the left anterior descending artery (LAD) involving its mid and distal segments was identified. The present case highlights a rare occurrence of spontaneous coronary artery dissection (SCAD) in a demographic typically unaffected by the condition - females aged 65 years and over. The atypical presentation underscores the importance of reporting such cases to prevent oversight. This patient's case is particularly noteworthy as it deviates from the typical predisposing factors associated with SCAD, such as youth, pregnancy, or stressors. Additionally, the case is unique in that it presented both SCAD and imaging findings consistent with takotsubo cardiomyopathy, suggesting a complex cardiac pathology deserving of further study and consideration.

Long-Lasting SARS-CoV-2 Infection With Post-COVID-19 Chronic Interstitial Pneumonia in a Patient With Chronic Lymphocytic Leukemia Treated Successfully With Intravenous Immunoglobulin.

Post-coronavirus disease 2019 (post-COVID-19) condition is a post-acute syndrome characterized by non-specific symptoms that remain for at least two months and typically appear three months after the start of the acute phase. Individuals with chronic lymphocytic leukemia (CLL) are considered to be at high risk of contracting COVID-19. It is also becoming increasingly evident that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine response is frequently lacking or insufficient. We present a 77-year-old male patient with CLL who had multiple hospitalizations for the management of pneumonia related to persistent COVID-19 infection due to hypogammaglobulinemia. He was subsequently treated with intravenous immunoglobulin (IVIG). This case emphasizes the importance of the early detection of hypogammaglobulinemia in patients with CLL and long COVID because of the potential therapeutic benefit of IVIG therapy. We also provide a literature review on COVID-19 infection in CLL patients, focusing mainly on the subset population of patients with hypergammaglobulinemia.

Stercoral Colitis-Induced Ischemia Mimicking acute Mesenteric Ischemia: A case report and Literature Review.

Stercoral colitis is a rare but serious condition characterized by inflammation of the colonic mucosa due to impacted and hardened faecal material. The word "stercoral" means "related to faeces". This condition usually develops due to the accumulation of hard stool masses in the colon, which cause localized inflammation and irritation. These faecalomas can exert persistent pressure on the colonic wall, causing damage and inflammation. Stercoral colitis presenting symptoms that mimic acute mesenteric ischemia is a diagnostic challenge for clinicians due to the overlap in clinical manifestations. Changes in bowel habits, bloating, and excruciating abdominal pain are potential manifestations of both illnesses, making it difficult to distinguish between them using clinical presentation. Diagnostic imaging, such as computed tomography scans, significantly discriminates between stercoral colitis and acute mesenteric ischemia. In cases where stercoral colitis mimics acute mesenteric ischemia, a thorough evaluation is essential to rule out vascular compromise. Timely and accurate diagnosis is crucial, as the management strategies for these two conditions differ significantly. Stercoral colitis often requires bowel evacuation and addressing the underlying faecal impaction. Acute mesenteric ischemia demands prompt vascular intervention to restore blood flow and prevent severe complications like bowel infarction. Given the potential overlap in symptoms and the critical importance of distinguishing between stercoral colitis and acute mesenteric ischemia, a multidisciplinary approach involving radiological imaging, clinical expertise, and timely intervention is essential for optimal patient care. This case highlights the importance of considering stercoral colitis when evaluating a patient with an acute abdomen, especially elderly patients with history of constipation. LEARNING POINTS: Constipation is a common condition that can lead to serious complications, especially in older people, and should be addressed as soon as possible.Early recognition of stercoral colitis and appropriate treatment can prevent critical consequences.Stercoral colitis can induce bowel ischemia, causing acute abdominal pain mimicking acute mesenteric ischemia.

Black Cohosh: An Uncommon Culprit of Bradycardia in Postmenopausal Women.

The use of herbal supplements has become increasingly prevalent, with black cohosh (BC) gaining popularity for managing menopausal symptoms. However, reports of adverse effects associated with BC are limited. We present a case of bradycardia linked to prolonged BC ingestion. A 76-year-old postmenopausal woman who has been taking BC for years has had syncopal attacks multiple times during the past years associated with bradycardia with the heart rate dropping to 30 beats/minute with no identifiable cause. Discontinuation of BC resulted in a gradual resolution of bradycardia, highlighting a plausible association. There were no additional pharmacological or invasive interventions required.

Sculpting the Silent Intricacies: A Rare Triad of Syphilitic Aneurysms Unveiled.

This case report revolves around a 73-year-old male patient who initially sought medical attention due to left lower extremity weakness. Suspicions of a potential vascular etiology arose during the initial clinical examination, prompting further investigation. Unexpectedly, computed tomography (CT) imaging of the abdomen and pelvis revealed the presence of three giant aneurysms. Concurrently, positive syphilis titers were identified. The patient's presentation, marked by focal neurological deficits, unveiled the incidental discovery of a triad of aneurysms involving the distal abdominal aorta, right common iliac, and left common iliac. The neurological symptoms observed in the patient were attributed to the compression within the left common iliac artery, leading to compromised blood flow to the lower extremity. Alternatively, the neurological deficits could be linked to neurosyphilis or a combination of both factors. This case underscores the critical role of considering syphilis in patients presenting with neurological symptoms. The unique discovery of extensive aortic abnormalities through imaging studies, specifically CT angiography, emphasized the importance of such diagnostic tools in unraveling complex and potentially life-threatening vascular pathologies. Recognizing the diverse manifestations of syphilis in patients with vast neurological symptoms is crucial for timely diagnosis and multidisciplinary management. This case emphasizes the need to keep a high index of suspicion for syphilis in individuals who have widespread aortic anomalies together with neurological symptoms, to sum up. The triad of aneurysms discovered incidentally in this 73-year-old patient underscores the intricate interplay between vascular and neurological manifestations. The timely diagnosis and multidisciplinary management of both the neurological and vascular aspects of this unique presentation are essential for ensuring optimal patient outcomes.

Targeted phototherapy using 308 nm Xecl monochromatic excimer laser for psoriasis at difficult to treat sites.

Psoriasis is a chronic inflammatory multisystem disease involving skin and joints affecting 1-3 % of the world population. The 308-nm excimer laser has been recently used in the treatment of psoriasis, especially localized psoriasis of scalp and palm and soles. The objective of the study is to evaluate the therapeutic efficacy and safety of a 308-nm excimer laser for the treatment of scalp and palmoplantar psoriasis. A total of 41 adult patients (25 males and 16 females) were enrolled in this study, of which 26 patients had lesions localized to scalp, and 15 patients had involvement of palm and soles. The mean age was 44.5 years (range 18-73). And, the mean duration of psoriasis in our patients was 15 years. They were treated with a 308-nm excimer laser. The initial dose was based on multiples of a predetermined minimal erythema dose, twice weekly for a maximum 12 weeks. Twenty-two of the 23 patients with scalp psoriasis showed improvement, while one patient showed no change; none experienced worsening of symptoms. The mean minimal erythema dose (MED) was found to be 383 mJ/cm(2) (range 180-650 mJ/cm(2)). The cumulative dose of irradiation was 1,841 mJ/cm(2) (range 600-2,500). The percentage improvement from baseline in PSSI score was 78.57 %. Side effects were seen in 20 patients (86.96 %) mainly in the form of erythema. Four patients developed mild relapse at the end of 6 months after the therapy. In 15 patients with palmoplantar psoriasis, the mean MED was found to be 415 mJ/cm(2) (range 200-950 mJ/cm(2)). The cumulative dose of irradiation was 28.4-115.5 J cm(2) (mean 59.1 J cm(2)). The mean number of treatments to achieve clearance (equal to 90 % reduction of PSI score) was 16. Two patients relapsed at the end of 6 months after the therapy. The 308-nm excimer laser is an effective, safe, easy, and relatively quicker method for the treatment of psoriasis at difficult to treat sites, with good results in a somewhat short time.

A 27-Year-Old Woman with an Exacerbation of Chronic Asthma Due to Influenza A Presenting with Pneumomediastinum, Retropharyngeal Emphysema, and Subcutaneous Emphysema.

BACKGROUND Influenza infection can trigger an asthma exacerbation, which can lead to spontaneous pneumomediastinum. This is a rare condition that typically occurs after a sudden increase in intra-alveolar pressure. Pneumomediastinum is usually a benign condition that can be treated with supportive care, and it can be accompanied by subcutaneous emphysema. However, it can progress to retropharyngeal emphysema, as reported in this case. This report is of a 27-year-old patient with past medical history of well-controlled asthma presenting for acute exacerbation of asthma secondary to influenza A infection who developed pneumomediastinum, subcutaneous emphysema, and retropharyngeal emphysema. To the best of our knowledge, there is only one case in literature that has reported a similar presentation secondary to influenza A infection. CASE REPORT We report a 27-year-old woman with well-controlled asthma who presented with chest pain, shortness of breath, throat pressure, dry cough, and expiratory wheezing as an acute exacerbation of asthma secondary to influenza A infection. On chest imaging, she was found to have spontaneous pneumomediastinum, subcutaneous emphysema, and retropharyngeal emphysema. Her symptoms were resolved with supportive measures and control of asthma symptoms. CONCLUSIONS This case highlights these atypical complications of asthma exacerbations. Although these complications are typically benign and can resolve with supportive measures, severe cases can lead to acute airway compromise, pneumothorax, tension pneumomediastinum, or tension pneumopericardium. This case also shows how important it is to consider chest radiographs in any young patient with an asthma exacerbation who has symptoms or signs suggestive of extra-alveolar air.

Long-term results of split-skin grafting in combination with excimer laser for stable vitiligo.

BACKGROUND: Some cases of focal or segmental vitiligo are refractory to medical treatment, and surgical management is the treatment of choice. Postsurgical exposure to ultraviolet B rays can lead to faster and better cosmetic results. OBJECTIVE: To determine the long-term results of combination therapy with split-skin-thickness grafting and 308-nm excimer laser for the management of stable focal or segmental vitiligo. PATIENTS AND METHODS: Seventeen patients (8 female, 9 male) with stable focal or segmental vitiligo not responding to nonsurgical modalities were treated with split-skin-thickness grafting and postgrafting with 32 sessions of 308-nm excimer laser, beginning 2 weeks after surgery. The patients were followed up every year for evaluation of results. RESULTS: All seventeen (100%) patients showed repigmentation, and overall results were graded as excellent in 12 patients and good in the other five at the end of excimer laser therapy. Final evaluation done at the end of 1 year revealed excellent results in all 17 patients. Two patients developed new vitiligo lesion on other parts of the body during follow-up. None of the patients developed depigmentation of the transplanted skin. CONCLUSION: Combination treatment with split-skin-thickness grafting and postsurgical exposure to 308-nm excimer laser in patients with stable focal or segmental vitiligo can lead to fast, cosmetically good, long-lasting results.

Comparative study on the efficacy, safety, and acceptability of imiquimod 5% cream versus cryotherapy for molluscum contagiosum in children.

To compare the efficacy, safety and acceptability of imiquimod (IMQ) 5% cream with cryotherapy for the treatment of molluscum contagiosum (MC) in children. Prospective, randomized, comparative, observer blinded study. A total of 74 children, with MC were divided randomly to receive treatment with either IMQ 5% cream (group A) 5 days a week or cryotherapy (group B) once a week until clinical cure or up to a maximum of 16 weeks. All the patients were followed up weekly during active treatment. The patients were followed-up for 6 months after clinical cure to look for recurrence. In the IMQ group (group A), the overall complete cure rate was 91.8% (34 of 37), 22 of the 37 patients cleared by the end of 6 weeks and 12 more patients cleared by the end of 12 weeks, while the remaining three patients (8.1%) did not clear even after 16 weeks. Whereas, in the cryotherapy group, all 37 patients achieved complete cure, 26 of 37 (70.27%) patients cleared after 3 weeks, and the remaining 11 (29.72%) cleared by the end of 6 weeks. No statistically significant difference was found between the overall complete cure rate in both groups at the end of maximum treatment period (16 weeks). Pain, bullae formation, pigmentary changes, and superficial scarring were more significantly common in the cryotherapy group compared with the IMQ group. Imiqimod 5% cream seems to be slow acting but an effective agent for the treatment of MC in children. IMQ appears to be practically painless and more cosmetically accepted treatment when compared with cryotherapy, and may be the preferred treatment of MC in children especially with numerous small lesions. Cryotherapy has the advantage of being rapidly effective, and is less expensive than IMQ and may be the preferred treatment for large solitary or few lesions.

A review on maintenance strategies for PV systems.

PV (PhotoVoltaic) systems gained popularity in being eco-friendly power supplies, reducing toxic gas emissions for energy production. Unfortunately it's been seen that efficiency reduction and output deficit are two common scenarios for PV systems when confronted with faulty events: this fact creates the crucially important need of knowing types of different possible faults and be able to detect them according to their ways of striking, timing and density of their leftovers. What comes after is fixing the damages, by preventing them from happening repeatedly and stop them from reaching the surface. Since knowing the fault without correcting it is counterproductive, maintenance strategies can reduce competencies of the system, accelerate operation time, and compensate the system in a way that prevents lowering in efficiency and consequently financial losses. This paper aims to present different schemes used in fault intervention categorized by preventive, corrective, predictive and urgent case faults maintenance methods with corresponding effects on environment. A critical comparison between different strategies is presented as well as an economical assessment of the maintenance costs and energy production increase. Each type is individually clarified to reveal what area of PV faults types it can withstand. With a recommendation on maintenance choice, an informative reference for researchers in the field is established to optimally maintain a sustainable PV system.

Changing demography of leprosy: Kuwait needs to be vigilant.

INTRODUCTION: Leprosy is an ancient, chronic, communicable disease. It is claimed that it has been 'eliminated' as a public health problem at the global level. However, sporadic new cases are increasingly being encountered, even in non-endemic countries such as ours. A more disturbing fact is the increase in the number of cases in the indigenous population. OBJECTIVES: The aim of this study was to analyze the magnitude of the leprosy problem in the region of Farwaniya, in which most of the immigrants in Kuwait live, based on detection and prevalence rates over the last 6 years, in addition to a clinico-pathological analysis of the collected data. PATIENTS AND METHODS: All clinically diagnosed cases of leprosy seen over a period of 6 years, from January 2003 to December 2008, were included in the study. Socio-demographic details and clinical features were recorded on a proforma. The results were compared to similar previous data from Kuwait, and to that from other countries in the region. RESULTS: Forty-six patients (38 male and eight female) aged 22-48 years (average 33.6 years), clinically diagnosed with leprosy, were enrolled. Of the enrolled patients, 89.1% were expatriates, while 10.9% were Kuwaiti citizens. The majority of patients (n=24) were from India, followed by Bangladesh (n=6), Egypt (n=5), Pakistan (n=3), and Indonesia, Philippines and Sri Lanka (n=1 each). The duration of signs and symptoms ranged from 1 to 24 months (average 4.7 months). A total of 58.5% of expatriate patients developed their symptoms 2-5 years after entry into Kuwait. Delayed diagnosis (after 12 weeks) was observed in 70.8%. Thirty-one patients (67.4%) had multibacillary leprosy (borderline lepromatous n=15, borderline type n=7, borderline tuberculoid n=5, and lepromatous leprosy n=4), while 15 patients (32.6%) had the paucibacillary form of leprosy (tuberculoid type n=8, borderline tuberculoid n=7). The detection of lepra bacilli in tissue sections was the most common diagnostic tool (67.4%), while nasal smears showed positive results in 28.3% of cases and the slit skin smear in 17.4%. CONCLUSIONS: This study shows that leprosy in the region of Farwaniya, Kuwait, which has predominantly been a disease of immigrants, has started to infect the Kuwaiti population; such cases may just represent the tip of the iceberg. Careful examination of immigrants on arrival and subsequent periodic regular check-ups are required to prevent the spread of the disease. Furthermore, early referral of suspected cases and screening of contacts, with initiation of treatment as early as possible, are essential to control the spread of leprosy in Kuwait.

Significant bronchospasm during sickle cell painful crises is associated with a lower peripheral eosinophil count.

BACKGROUND: Bronchial hyperresponsiveness and/or bronchospasm are recognized complications of sickle cell disease. OBJECTIVE: The aim of this study was to investigate the presence of bronchospasm during painful crises, using simple spirometry in patients with sickle cell disease. METHODS: A prospective, non-randomized study was undertaken in patients with homozygous sickle cell disease, who presented with increasing pain. A painful crisis was defined as any increase in bodily pains necessitating hospital admission. A 15% increase in FEV(1) following salbutamol nebulization was considered significant. RESULTS: Thirty-nine patients took part in the study. Significant bronchodilator responses were demonstrable in 48.7% of patients during painful crises. Patients with such a response had a significantly lower peripheral blood eosinophil count (mean count 0.17 x 10(9)/L vs. 0.445 x 10(9)/L, P = 0.02, confidence interval for difference between groups, 0.0, 0.39). Furthermore, the magnitudes of the bronchodilator responses were related to the degree of lowering of peripheral blood eosinophil counts (r(s) = -0.344, P = 0.037). CONCLUSION: Significant bronchospasm is demonstrable in a sizeable proportion of patients presenting with painful sickle cell crises. There seems to be a negative correlation between the magnitude of bronchospasm and the peripheral blood eosinophil count. We postulate a possible role for pulmonary sequestration of eosinophils in the pathophysiology of bronchospasm in sickle cell disease patients.
