Common Kidney Diseases and Their Clinical Features

Immunoglobulin A (IgA) Nephropathy, Kimmelstiel Wilson Lesions, Cast Nephropathy, Minimal Change Disease, and Thin Basement Membranes are some of the common kidney diseases that affect people. Each of these diseases has unique clinical features that help in their diagnosis.

IgA Nephropathy, also known as Berger’s disease, is the most common cause of glomerulonephritis worldwide. It is characterized by predominant IgA deposition in the glomerular mesangium. Clinical features range from asymptomatic haematuria to rapidly progressive glomerulonephritis.

Kimmelstiel–Wilson Lesions, also known as nodular glomerulosclerosis, is a complication of diabetes mellitus. It is characterized by the formation of nodules of hyaline material in regions of glomerular capillary loops in the glomerulus.

Cast Nephropathy, also known as myeloma cast nephropathy, is the formation of urinary casts in the renal tubules from free immunoglobulin light chains, causing intratubular obstruction and damage, which leads to renal failure in the context of multiple myeloma.

Minimal Change Disease, also known as lipoid nephrosis or nil disease, arises from a histopathologic lesion in the glomerulus and is characterized by intense proteinuria leading to oedema and intravascular volume depletion.

Thin Basement Membranes is a group of inherited heterogeneous disorders involving the basement membranes of the kidney and frequently affecting the cochlea and eye as well. It is characterized by splitting and lamellation of the glomerular basement membrane.

In conclusion, understanding the clinical features of these common kidney diseases is crucial in their diagnosis and management.

Preventing Contrast-Induced Nephropathy: Strategies and Considerations

Contrast-induced nephropathy (CIN) is a common complication of IV contrast administration, particularly in patients with pre-existing renal impairment. CIN is characterized by a decline in renal function within 48-72 hours of contrast exposure. To prevent CIN, strategies that focus on maintaining intravascular volume expansion are crucial.

Intravenous (IV) saline 0.9% is preferred over 0.45% saline as it enhances intravascular volume expansion and prevents renin-angiotensin activation. Oral fluids are beneficial but not as effective as IV hydration. Volume expansion should begin 6 hours before the procedure and continue for 6-24 hours post-procedure, with post-procedure hydration being more important than pre-procedure hydration.

Diuretics alone are not recommended, but a recent meta-analysis suggests that furosemide with matched hydration may reduce the incidence of CIN in high-risk patients. Fluid restriction is not recommended, and oral fluids should be encouraged.

Dialysis is required in less than 1% of patients with CIN, with a slightly higher incidence in patients with underlying renal impairment and those undergoing primary percutaneous coronary intervention for myocardial infarction. N-Acetylcysteine (NAC) supplementation has been associated with a significant decrease in CIN risk and blood creatinine levels, but it does not reduce mortality or the need for dialysis.

In conclusion, preventing CIN requires a multifaceted approach that includes maintaining intravascular volume expansion, avoiding fluid restriction, and considering NAC supplementation in high-risk patients.

SGLT-2 inhibitors, such as dapaglifozin, have been linked to a severe and rapidly progressing infection called necrotising fasciitis of the genitalia or perineum, also known as Fournier’s gangrene. This condition is caused by bacterial flora and is more common in diabetic and immunocompromised patients. It can lead to multiple organ failure and sepsis, making early surgical debridement and antibiotics crucial for management. It is important to note that Fournier’s gangrene is a serious adverse effect of SGLT-2 inhibitors, while the other options presented in the question are not associated with this condition.

Understanding SGLT-2 Inhibitors

SGLT-2 inhibitors are medications that work by blocking the action of a protein called sodium-glucose co-transporter 2 (SGLT-2) in the kidneys. This results in a decrease in the amount of glucose that is reabsorbed by the body and an increase in the amount of glucose that is excreted in the urine. Examples of SGLT-2 inhibitors include canagliflozin, dapagliflozin, and empagliflozin.

While SGLT-2 inhibitors can be effective in treating type 2 diabetes mellitus, they can also have some important adverse effects. One of the most common side effects is an increased risk of urinary and genital infections, which can occur due to the increased amount of glucose in the urine. Fournier’s gangrene, a rare but serious bacterial infection of the genital area, has also been reported in some cases.

Another potential complication of SGLT-2 inhibitors is normoglycemic ketoacidosis, a condition in which the body produces high levels of ketones even when blood sugar levels are normal. This can be a serious and potentially life-threatening condition if left untreated. Additionally, there is an increased risk of lower-limb amputation in patients taking SGLT-2 inhibitors, so it is important to closely monitor the feet for any signs of injury or infection.

Despite these potential risks, SGLT-2 inhibitors can also have some positive effects on overall health. Many patients taking these medications experience weight loss, which can be beneficial in managing type 2 diabetes mellitus. As with any medication, it is important to discuss the potential benefits and risks of SGLT-2 inhibitors with a healthcare provider before starting treatment.

Relaxation of the bladder outlet and urethra caused by doxazosin can exacerbate stress incontinence symptoms. This medication, classified as an alpha blocker, is commonly prescribed for hypertension and benign prostatic hyperplasia-related urinary retention. Therefore, doxazosin is the appropriate response.

Understanding Urinary Incontinence: Causes, Classification, and Management

Urinary incontinence (UI) is a common condition that affects around 4-5% of the population, with elderly females being more susceptible. Several risk factors contribute to UI, including advancing age, previous pregnancy and childbirth, high body mass index, hysterectomy, and family history. UI can be classified into different types, such as overactive bladder (OAB)/urge incontinence, stress incontinence, mixed incontinence, overflow incontinence, and functional incontinence.

Initial investigation of UI involves completing bladder diaries for at least three days, vaginal examination, urine dipstick and culture, and urodynamic studies. Management of UI depends on the predominant type of incontinence. For urge incontinence, bladder retraining and bladder stabilizing drugs such as antimuscarinics are recommended. For stress incontinence, pelvic floor muscle training and surgical procedures such as retropubic mid-urethral tape procedures may be offered. Duloxetine, a combined noradrenaline and serotonin reuptake inhibitor, may also be used as an alternative to surgery.

In summary, understanding the causes, classification, and management of UI is crucial in providing appropriate care for patients. Early diagnosis and intervention can significantly improve the quality of life for those affected by this condition.

The patient in this vignette meets the criteria for AKI Stage 1, which is characterized by a moderate increase in serum creatinine (1.5-1.9 times the baseline) or reduced urine output (<0.5 mL/kg/hr) for at least 6 hours. The patient has risk factors such as age, diabetes mellitus, and NSAID use for back pain, which can contribute to AKI. It is important to note that AKI is a classification and not a diagnosis. AKI Stage 2 is characterized by a more significant increase in serum creatinine (2-2.9 times the baseline) or reduced urine output for at least 12 hours. The vignette does not show renal function that is severe enough to meet this classification. AKI Stage 3 is the most severe stage, with a serum creatinine increase of 3 times or more from baseline or reduced urine output for at least 24 hours. Again, the patient’s renal function is not severe enough to meet this classification. There is no AKI Stage 4 or 5. Chronic kidney disease is classified from stages 1-5 based on the patient’s estimated glomerular filtration rate (eGFR). A patient with CKD Stage 4 would have an eGFR of 15-29 ml/min/1.73m², while a patient with CKD Stage 5 would have end-stage renal disease with an eGFR <15 ml/min/1.73m² or be receiving renal replacement therapy. The NICE guidelines for acute kidney injury (AKI) identify risk factors such as emergency surgery, CKD, diabetes, and use of nephrotoxic drugs. Diagnostic criteria include a rise in creatinine, fall in urine output, or fall in eGFR. The KDIGO criteria are used to stage AKI, with stage 3 indicating the most severe cases. Referral to a nephrologist is recommended for certain cases, such as AKI with no known cause or inadequate response to treatment. Complications of AKI include CKD, hyperkalaemia, metabolic acidosis, and fluid overload.

Understanding Chronic Kidney Disease Stages and GFR Categories

Chronic kidney disease (CKD) is a condition characterized by a gradual loss of kidney function over time. To assess the severity of CKD, healthcare professionals use a staging system based on the glomerular filtration rate (GFR), which measures how well the kidneys are filtering waste from the blood.

A GFR of >90 without other evidence of kidney disease indicates normal renal function. However, if the GFR falls below this level, the patient may be classified into one of the following stages:

– CKD stage 2: GFR 60-89 ml/min/1.73 m2 (mildly decreased)
– CKD stage 3a: GFR 45-59 ml/min/1.73 m2 (mildly to moderately decreased)
– CKD stage 3b: GFR 30-44 ml/min/1.73 m2 (moderately to severely decreased)
– CKD stage 4: GFR 15-29 ml/min/1.73 m2 (severely decreased)
– CKD stage 5: GFR <15 ml/min/1.73 m2 (kidney failure) To further assess the risk of adverse outcomes, the 2008 NICE guideline on CKD recommends subdividing stage 3 into 3a and 3b and adding the suffix P to denote significant proteinuria at any stage. Significant proteinuria is defined as a urinary albumin:creatinine ratio (ACR) of 30 mg/mmol or higher. Understanding the GFR categories and CKD stages can help healthcare professionals diagnose and manage CKD, as well as educate patients on their kidney function and potential risks.

First-line treatment for benign prostatic hyperplasia involves the use of alpha-1 antagonists.

Benign prostatic hyperplasia (BPH) is a common condition that affects older men, with around 50% of 50-year-old men showing evidence of BPH and 30% experiencing symptoms. The risk of BPH increases with age, with around 80% of 80-year-old men having evidence of the condition. BPH typically presents with lower urinary tract symptoms (LUTS), which can be categorised into voiding symptoms (obstructive) and storage symptoms (irritative). Complications of BPH can include urinary tract infections, retention, and obstructive uropathy.

Assessment of BPH may involve dipstick urine tests, U&Es, and PSA tests. A urinary frequency-volume chart and the International Prostate Symptom Score (IPSS) can also be used to assess the severity of LUTS and their impact on quality of life. Management options for BPH include watchful waiting, alpha-1 antagonists, 5 alpha-reductase inhibitors, combination therapy, and surgery. Alpha-1 antagonists are considered first-line treatment for moderate-to-severe voiding symptoms, while 5 alpha-reductase inhibitors may be indicated for patients with significantly enlarged prostates and a high risk of progression. Combination therapy and antimuscarinic drugs may also be used in certain cases. Surgery, such as transurethral resection of the prostate (TURP), may be necessary in severe cases.

Medical Conditions that Cause Bilateral Oedema: Inferior Vena Cava Obstruction, Hypoalbuminaemia, Deep Venous Thrombosis, Heart Failure, and Hyponatraemia

Bilateral oedema, or swelling in both legs, can be caused by various medical conditions. One of these is inferior vena cava obstruction, which occurs when a renal mass or thrombus compresses the inferior vena cava, preventing venous drainage of the lower limbs. This obstruction can also cause venous engorgement and dilated veins around the umbilicus. Hypoalbuminaemia, on the other hand, causes a generalised oedema that can be seen in the face, upper and lower limbs, and abdomen. Deep venous thrombosis, which presents with painful swelling and erythema in the affected lower limb, can also cause bilateral symptoms if it occurs in the inferior vena cava. Heart failure, which causes bilateral dependent oedema due to fluid overload, is another possible cause of bilateral oedema. Finally, severe hyponatraemia resulting from fluid overload can cause a generalised symmetrical pattern of oedema that affects the upper limbs as well. Treatment for bilateral oedema depends on the underlying cause.

Common Medications and their Association with Acute Tubulointerstitial Nephritis

Acute tubulointerstitial nephritis is a condition characterized by inflammation of the renal tubules and interstitium, often caused by medications. Here are some common medications and their association with acute tubulointerstitial nephritis:

1. Prednisolone: This medication is safe to continue as it is already used as a management option for acute tubulointerstitial nephritis.

2. Allopurinol: This medication should be discontinued as it is known to cause acute tubulointerstitial nephritis.

3. Amoxicillin: This beta-lactam antibiotic is one of the most common drug-related causes of acute tubulointerstitial nephritis and may need to be withdrawn.

4. Diclofenac: Non-steroidal anti-inflammatory drugs, such as diclofenac, are another common cause of tubulointerstitial nephritis and should be stopped in any form of acute kidney injury.

5. Omeprazole: Proton pump inhibitors, such as omeprazole, are known to be a triggering medication for acute tubulointerstitial nephritis and should be withdrawn promptly to allow for renal function recovery.

It is important to be aware of these associations and to monitor patients for symptoms of acute tubulointerstitial nephritis when prescribing these medications.

To prevent future torsion of the other testicle, it is recommended that both testes be fixed during testicular torsion surgery. While manual rotation may be successful in some cases, it is not appropriate once surgery has begun. If a bell clapper deformity is present, both testes should be fixed if they are still viable. Given the short duration of symptoms (only six hours), it is unlikely that surgical removal (orchiectomy) will be necessary.

Testicular Torsion: Causes, Symptoms, and Treatment

Testicular torsion is a medical condition that occurs when the spermatic cord twists, leading to testicular ischaemia and necrosis. This condition is most common in males aged between 10 and 30, with a peak incidence between 13 and 15 years. The symptoms of testicular torsion are sudden and severe pain, which may be referred to the lower abdomen. Nausea and vomiting may also be present. On examination, the affected testis is usually swollen, tender, and retracted upwards, with reddened skin. The cremasteric reflex is lost, and elevation of the testis does not ease the pain (Prehn’s sign).

The treatment for testicular torsion is urgent surgical exploration. If a torted testis is identified, both testes should be fixed, as the condition of bell clapper testis is often bilateral.

Minimal change disease is a condition that typically presents as nephrotic syndrome, with children accounting for 75% of cases and adults accounting for 25%. While most cases are idiopathic, around 10-20% have a known cause, such as certain drugs, Hodgkin’s lymphoma, thymoma, or infectious mononucleosis. The pathophysiology of the disease involves T-cell and cytokine-mediated damage to the glomerular basement membrane, resulting in polyanion loss and reduced electrostatic charge, which increases glomerular permeability to serum albumin. The disease is characterized by nephrotic syndrome, normotension (hypertension is rare), and highly selective proteinuria, with only intermediate-sized proteins such as albumin and transferrin leaking through the glomerulus. Renal biopsy shows normal glomeruli on light microscopy, but electron microscopy reveals fusion of podocytes and effacement of foot processes.

Management of minimal change disease typically involves oral corticosteroids, which are effective in 80% of cases. For steroid-resistant cases, cyclophosphamide is the next step. The prognosis for the disease is generally good, although relapse is common. Approximately one-third of patients have just one episode, one-third have infrequent relapses, and one-third have frequent relapses that stop before adulthood.

Managing a Patient with Suspected Chronic Kidney Disease

When a patient presents with suspected chronic kidney disease (CKD), it is important to perform a thorough examination and urinalysis to confirm the diagnosis. While patients with CKD stages 1-3 may not exhibit symptoms, those in stages 4-5 may experience endocrine/metabolic derangements or disturbances in water or electrolyte balance. Anaemia is often one of the first signs of CKD, but the lack of physical findings on examination does not exclude kidney disease. Initial screening for proteinuria can be done with a standard urine dipstick, and further testing may be necessary if the test is positive. Referral to a nephrology outpatient may be necessary, depending on the severity of the CKD. ACE inhibitors should only be started once the patient’s baseline renal function has been established, and blood tests should be rechecked in 2 weeks. Immediate admission is only necessary for patients with CKD stage 5 who present with acute indications for dialytic therapy.

The symptoms and pain caused by testicular torsion are usually more severe and acute, while a patient with mumps would experience prodromal symptoms and parotitis.

Epididymo-orchitis is a condition where the epididymis and/or testes become infected, leading to pain and swelling. It is commonly caused by infections spreading from the genital tract or bladder, with Chlamydia trachomatis and Neisseria gonorrhoeae being the usual culprits in sexually active younger adults, while E. coli is more commonly seen in older adults with a low-risk sexual history. Symptoms include unilateral testicular pain and swelling, with urethral discharge sometimes present. Testicular torsion, which can cause ischaemia of the testicle, is an important differential diagnosis and needs to be excluded urgently, especially in younger patients with severe pain and an acute onset.

Investigations are guided by the patient’s age, with sexually transmitted infections being assessed in younger adults and a mid-stream urine (MSU) being sent for microscopy and culture in older adults with a low-risk sexual history. Management guidelines from the British Association for Sexual Health and HIV (BASHH) recommend ceftriaxone 500mg intramuscularly as a single dose, plus doxycycline 100mg orally twice daily for 10-14 days if the organism causing the infection is unknown. Further investigations are recommended after treatment to rule out any underlying structural abnormalities.

The eGFR (estimated glomerular filtration rate) is determined by several variables, including CAGE, which stands for Creatinine, Age, Gender, and Ethnicity.

Understanding Chronic Kidney Disease: eGFR and Classification

Chronic kidney disease (CKD) is a condition that affects the kidneys’ ability to filter waste products from the blood. Serum creatinine, a commonly used measure of kidney function, may not provide an accurate estimate due to differences in muscle mass. To address this, formulas such as the Modification of Diet in Renal Disease (MDRD) equation were developed to estimate the glomerular filtration rate (eGFR). The MDRD equation takes into account variables such as serum creatinine, age, gender, and ethnicity.

It is important to note that certain factors may affect the accuracy of eGFR results, such as pregnancy, muscle mass, and recent consumption of red meat. CKD can be classified based on eGFR, with stage 1 indicating a GFR greater than 90 ml/min with some sign of kidney damage on other tests. Stage 2 indicates a GFR of 60-90 ml/min with some sign of kidney damage, while stage 3a and 3b indicate a moderate reduction in kidney function with GFR ranges of 45-59 ml/min and 30-44 ml/min, respectively. Stage 4 indicates a severe reduction in kidney function with a GFR range of 15-29 ml/min, while stage 5 indicates established kidney failure with a GFR less than 15 ml/min, which may require dialysis or a kidney transplant. It is important to note that if all kidney tests are normal, there is no CKD.

Diagnostic Tests for Renal Artery Stenosis

Renal artery stenosis is a condition that can lead to reduced blood flow to the kidneys. There are several diagnostic tests that can be used to assess for this condition.

Intra-arterial renal arteriography is an invasive test that involves passing radio-opaque dye through the renal arteries to assess for normal flow or stenosis. This is considered the gold-standard test for diagnosing renal artery stenosis. It can also be used as a therapeutic modality if stents can be used to increase the lumen of the artery.

Renal ultrasound scan can be used to assess for a shrunken appearance of the affected kidney and reduced vascular flow in the renal artery. Duplex ultrasound can augment this scan.

Peripheral plasma renin activity is no longer considered suitable for initial testing for renovascular disease. Investigations demonstrating the presence of stenosis or occlusion of the renal artery are preferred.

Magnetic resonance imaging (MRI) arteriography can be performed to assess for patent renal arteries or stenosis. However, a plain MRI without contrast would not be as effective as an intra-arterial examination.

A 24-hour urinary protein test may be arranged to assess for other causes of reduced renal function, but it would not be useful in assessing for patent renal arteries.

Overall, a combination of these tests may be used to diagnose renal artery stenosis and determine the best course of treatment.

Treatment Options for Benign Prostatic Hyperplasia (BPH)

Benign prostatic hyperplasia (BPH) is a common condition in men over 40 years old, characterized by non-cancerous growth of the prostate gland. This can lead to lower urinary tract symptoms (LUTS) that affect quality of life, such as obstructive symptoms (difficulty urinating) and irritative symptoms (frequent urination). While prostate cancer can present with similar symptoms, a reassuring biopsy can rule out cancer.

Alpha-blockers, such as tamsulosin and doxazosin, are commonly used to treat moderate to severe symptomatic BPH, regardless of prostate size. These medications work by blocking α-adrenoreceptors in the prostate, prostatic urethra, and bladder neck, leading to decreased muscle tone and reduced bladder obstruction.

Dutasteride and finasteride are both 5-α-reductase inhibitors (5ARIs) that block the production of dihydrotestosterone and reduce prostate volume. While there is no difference in clinical efficacy between the two agents, finasteride takes longer to show its effects. Current guidelines recommend 5ARIs for men with LUTS and a prostate larger than 30 g or a PSA level >1.4 ng/ml who are at high risk of progression. However, alpha-blockers remain the first-line agents for pharmacological treatment.

Testosterone replacement therapy is not indicated for the treatment of BPH, and beta-blockers are not effective in managing BPH/LUTS.

A non-contrast abdomino-pelvic/KUB CT scan is the preferred imaging modality for diagnosing nephrolithiasis in patients with a history of gout. This test has a high sensitivity and specificity and can also detect other pathologies.
Intravenous urography is less sensitive and requires IV contrast material, which can cause allergic reactions or renal failure.
Renal ultrasonography is useful in pregnancy or in combination with a KUB radiograph but is less accurate for diagnosing ureteral stones.
Retrograde ureterography is rarely performed for diagnostic purposes but is essential when surgery is necessary.
Uric acid stones are associated with low urine pH, high purine intake, or malignancy, and can be treated with allopurinol or alkali therapy depending on the patient’s uric acid levels.

Understanding Urinary Tract Infections in Children

Urinary tract infections (UTIs) are common in children and can present with a variety of symptoms. In older children, diarrhoea with or without mucus may be a presenting symptom, especially with E. coli infection. While amoxicillin is a commonly used antibiotic, current guidelines recommend trimethoprim or nitrofurantoin for lower UTIs and co-amoxiclav for upper UTIs.

Anatomical abnormalities of the urinary tract increase a child’s susceptibility to UTIs, but they are not present in the majority of cases. Imaging studies are not necessary for infants and children with a first episode of cystitis or a first febrile UTI who respond well to treatment and have a normal voiding pattern. Ultrasonography is the preferred imaging study for children with UTIs.

Escherichia coli is the most common organism isolated in paediatric UTIs, but other organisms such as fungi and viruses can also cause infection. Poor containment of infection is more common in infants younger than 2 months, and UTIs can spread to the kidneys and bloodstream if left untreated.

Understanding the symptoms and treatment options for UTIs in children is important for prompt diagnosis and management.

Bladder cancer is a prevalent type of urologic cancer that has a high recurrence rate. The most common type is transitional cell carcinoma, which is associated with environmental exposure, particularly smoking and certain occupations. Symptoms include painless gross hematuria, irritative bladder symptoms, and pelvic pain. Diagnosis is made through cystoscopy, which allows for biopsy and resection of papillary tumors. Treatment for non-muscle-invasive bladder cancer involves transurethral resection of the bladder tumor, followed by intravesical chemotherapy, intravesical BCG vaccine, and repeat resection and/or cystectomy in persistent or recurrent high-risk disease. Muscle-invasive bladder cancer is treated surgically, possibly with neoadjuvant chemotherapy.

Chronic urinary tract infections typically present as dysuria or irritative voiding symptoms and are most commonly caused by infection with the original bacterial isolate in young, otherwise healthy women. Women with recurrent symptomatic UTIs can be treated with continuous or post-coital prophylactic antibiotics.

Interstitial cystitis is an ongoing inflammation of the lower urinary tract that is not caused by pathogenic organisms. It affects mainly women over the age of 40 and presents as severe lower abdominal pain and polyuria. It is generally a diagnosis of exclusion.

Analgesic nephropathy is characterized by kidney injury caused by excessive use of analgesic medications such as aspirin and other NSAIDs and paracetamol. This leads to renal papillary necrosis and chronic interstitial nephritis. Most healthy kidneys contain enough physiologic reserve to compensate for this NSAID-induced decrease in blood flow.

Acute interstitial nephritis is a type of hypersensitivity nephropathy that is often drug-associated. Patients present with an abrupt onset of renal dysfunction, fever, and occasionally a rash.

A 68-year-old man presents with hypocalcaemia and a prolonged QT interval, which can increase the risk of cardiac arrhythmias such as Torsades de pointes. Urgent intravenous calcium gluconate is the recommended treatment for severe hypocalcaemia, which can cause symptoms such as hand and foot spasming, tetany, and seizures. Checking the vitamin D level is important for identifying the cause of hypocalcaemia, but it is not the next best step in managing this patient’s acute condition. Oral calcium carbonate supplementation may be useful in some cases, but intravenous calcium is the preferred treatment for severe hypocalcaemia. Levothyroxine is not indicated for this patient, as hypothyroidism has not been diagnosed and urgent IV calcium gluconate should be given.

Understanding Hypocalcaemia: Its Causes and Management

Hypocalcaemia is a medical condition characterized by low levels of calcium in the blood. It can be caused by various factors such as vitamin D deficiency, chronic kidney disease, hypoparathyroidism, pseudohypoparathyroidism, rhabdomyolysis, magnesium deficiency, massive blood transfusion, and acute pancreatitis. In some cases, contamination of blood samples with EDTA may also lead to falsely low calcium levels.

To manage severe hypocalcaemia, which may manifest as carpopedal spasm, tetany, seizures, or prolonged QT interval, intravenous calcium replacement is necessary. The preferred method is through the administration of intravenous calcium gluconate, with a recommended dose of 10ml of 10% solution over 10 minutes. However, it is important to note that intravenous calcium chloride may cause local irritation. ECG monitoring is also recommended during the treatment process. Further management of hypocalcaemia depends on the underlying cause.

In summary, hypocalcaemia is a condition that can be caused by various factors, and its management depends on the severity of the symptoms and the underlying cause. Intravenous calcium replacement is the preferred method for severe cases, and ECG monitoring is recommended during treatment.
